Clip matching balance: Mo ft sin clip in repeated sugar degree rate mmmmM Dandong 518 internal combustion engine parts (Group) Co., Ltd. (Liaoning 118009) Liu Tianjia CNC machine tool has the ability to process complex parts and processing precision, etc., making it It has been widely used in processing and manufacturing in various fields. In addition to the replacement of its functions, only the correct and reasonable operation of the machine tool can really make its use.
Nowadays, many CNC machine tools are in use. Because there is no corresponding high-tech measuring method (such as three-coordinate measuring instrument, etc.), most of them have to manually align and measure the workpiece, especially in the process of some repetitive parts processing. When labor costs, it affects production efficiency. How to improve this situation, only to design a simple and practical auxiliary fixture.
Our CNC machine tools mainly process the mold electrodes, and the electrodes are repaired after each electrical machining. Although the electrode workpiece has a reference line, the use of multiple times is ambiguous, and the artificial error between the electrodes makes it difficult to ensure the accuracy of the processed electrode position, and even wastes. In response to this problem, we have designed a very simple and practical V-shaped iron auxiliary fixture. See, in which the Y-axis surface positioning body of the fixture is embedded in the T-shaped groove of the table. See, the positioning body and the T-shaped groove cooperate with f or (the maximum clearance is not greater than zero is preferred). In order to ensure the positional tolerance of the x, y positioning surface and the mechanical coordinate of the machine tool, the positioning pin should be inserted after the fixed positioning body (that is, the positioning pin can be inserted at the appropriate position on the positioning body, and other fixing methods can also be used), and the X, y positioning surfaces are respectively Finishing, so that the machine tool coordinate position tolerance is guaranteed. In this way, when machining the electrode workpiece, the two positioning surfaces of the workpiece are first processed, and the workpiece is fixed in close contact with the positioning surface of the fixture, the workpiece zero point is set, and the absolute coordinate value is recorded. When the workpiece is repeatedly reworked, clean, position, and fix the workpiece, start the machine to record the coordinate value position, set the zero point to process, or set the origin to join the workpiece program. Modify the 2-axis zero or z-axis tool compensation, you can add T-shaped (20) T-shaped groove width Peng Shuai processing the inner hole on the lathe, especially the ultra-deep inner hole. According to the usual processing method, only the tailstock can be used. The drill sleeve is drilled.
This method has a good centering effect, and generally drills shallow holes. For some deeper holes, it is not so convenient to use the tailstock to drill holes. It is often necessary to drill a deep hole to repeatedly shake the tailstock handle many times. Especially when drilling, the tailstock must be dragged due to the long drilling depth. Drilling relies on manual feeling, it is difficult to remove chips, and it is slightly intentional. The drill bit is easy to get stuck in the inner hole, and the labor intensity of the worker is large and the efficiency is not high. For the difficulty of drilling deep holes, we use the Mohs magazine to be mounted on the tool holder for deep hole drilling. The Mohs elastic body is selected according to the number of the Mohs taper of the drill bit, and the corresponding inner taper sleeve is used. It is a cone sleeve and is a workpiece diagram.
The method of using and installing the clip body is as follows: 1 First, the Mohs clip body positioning surface is level with the tool holder press groove, and the drill bit selected according to the size to be processed is loaded into the Mohs magazine. Inside the cone, press the tool holder pressure groove set screw. 2 When designing the clip body, it is necessary to ensure that the center of the drill bit and the height of the tailstock center of the cone clamp in the Mohs clip are the same. 3 In order to ensure the concentricity requirement of the drilling of the workpiece, when drilling the deep inner hole, generally, a hole is drilled with the tailstock, and then the drill bit of the elastic body is moved in the distance of the sliding plate, or the dial gauge is used to correct the position. Drilling can be done using a magazine body drill mounted on the tool holder. 4 This kind of drill bit drilled on the lathe tool holder can be used for automatic deep feed, which can widen the drilling depth and reduce the labor intensity of the operator. It is very convenient to change and clamp the drill bit. Operation, this deep hole drilling method is stable and reliable, and the deep hole drilled reaches the design and process requirements, which is worthy of the use of the peers.
The amount of work rework. By adding such a simple and convenient auxiliary fixture, the positioning time of the workpiece is eliminated, and the human error is basically eliminated, which improves the production efficiency and the processing quality.
