Description

Technical Field

[0001] The utility model relates to the technical field of the swing shaft of an angle milling head, in particular to a special measuring device for the swing shaft of an angle milling head. Background Technique

[0002] An angle milling head is installed on a milling machine and connected to the main shaft, and is a machine tool accessory used to drive a milling cutter to rotate. It is a main component of machine tool equipment. The rotation accuracy of the swing shaft of the angle milling head is directly related to the machining accuracy during the five-axis linkage of the machine tool. Therefore, during the debugging stage of the machine tool, it is particularly important to perform laser compensation on the rotation accuracy error of the swing shaft on the angle milling head.

[0003] In the Chinese utility model patent application number: CN202021646461.3, a special measuring device for the swing shaft of an angle milling head is disclosed. It is made of aluminum alloy material, with a light overall mass, and hollow grooves for reducing mass are designed on the bottom plate and the side plate. Therefore, when the swing shaft rotates, it will not be deformed by the weight of the tooling rack. It has good reliability during use, and after connecting the calibration device, it can accurately compensate for the error of the rotation accuracy when the angle milling head swings.

[0004] Although the above patent realizes the function of assisting in measuring the swing shaft of the angle milling head, however, the above patent has the following disadvantages in use: the base and the vertical plate of the above special measuring device for the swing shaft of the angle milling head are both installed and fixed with a triangular support plate through multiple groups of bolts. When installing, it is necessary to hold each component firmly before tightening the bolts. The operation steps are cumbersome, and when disassembling and assembling, auxiliary tools such as screwdrivers are required. Without auxiliary tools, disassembly and assembly cannot be carried out, and the applicability is poor and it is not convenient to use. Therefore, we propose a special measuring device for the swing shaft of an angle milling head. Content of the Utility Model

When installing, it is necessary to hold each component firmly before tightening the bolts. The operation steps are cumbersome, and when disassembling and assembling, auxiliary tools such as screwdrivers are required. Without auxiliary tools, disassembly and assembly cannot be carried out, and the applicability is poor.

Mounting blocks 6 are equidistantly and fixedly connected to one side of the base 1 and one side of the vertical plate 3. A fixing groove 9 for cooperating with the connecting block 14 is opened inside the mounting block 6. A connecting shaft 17 is rotatably connected inside the triangular support plate 2. One end of the connecting shaft 17 is fixedly connected with a turntable 15. A convex block 24 is fixedly connected to the top of the turntable 15. A connecting frame 18 is fixedly connected to one side of the sliding frame 19. A transmission groove 23 for cooperating with the convex block 24 is opened inside the connecting frame 18; when laser electric repair is performed on the swing shaft of the angle milling head, the base 1 is connected to the end face of the swing shaft, and the vertical plate 3 is connected to the wireless rotary shaft calibration device, and then a laser interferometer is used to detect the error, so that the compensation of the rotation accuracy error can be accurately realized during the swing of the swing shaft of the angle milling head. The connecting shaft 17 drives the convex block 24 to rotate through the turntable 15, so as to cooperate with the transmission groove 23, so that the convex block 24 squeezes and drives the connecting frame 18 to slide, and then drives the sliding frame 19 to move. The movement of the sliding frame 19 drives the connecting block 14 to move, so that the connecting block 14 moves into the fixing groove 9, thereby locking the position of the mounting block 6, which is convenient for installing and fixing the base 1 and the vertical plate 3 to the triangular support plate 2.

[0027] Further, positioning holes 4 are equidistantly arranged inside the base 1, a process hole 7 is arranged inside the base 1 and on one side of the positioning hole 4, and laser test holes 10 are equidistantly arranged on one side of the vertical plate 3.

The slider 26 is fixedly connected to the plug rod 27. A spring 25 is sleeved on the outside of the plug rod 27 and on one side of the slider 26. The setting of the slider 26 can limit the movement of the plug rod 27. The spring 25 drives the slider 26 to move back to its original position. The position of the knob 12 can be limited and fixed by moving the plug rod 27 into the inside of the slot 13 to prevent accidental touch.

[0032] During use, when laser electric repair is performed on the swing axis of the swing angle milling head, connect the base 1 to the end face of the swing axis, and connect the vertical plate 3 to the wireless rotary axis calibration device. Then, use a laser interferometer to detect the error, so that the rotary precision error can be accurately compensated during the swing of the swing axis of the swing angle milling head. When installing the base 1 and the vertical plate 3 with the triangular support plate 2, place the triangular support plate 2 on the top of the base 1, then push the positioning block 8 into the positioning groove 5, and pull the insertion rod 27 to make the insertion rod 27 move out of the insertion slot 13. Then, the knob 12 can be rotated. The knob 12 drives the second bevel gear 22 to rotate through the rotating shaft 16. The second bevel gear 22 drives the connecting shaft 17 to rotate through the first bevel gear 21. The connecting shaft 17 drives the convex block 24 to rotate through the turntable 15, so as to cooperate with the transmission groove 23, so that the convex block 24 squeezes and drives the connecting frame 18 to slide. The connecting frame 18 drives one of the sliding frames 19 to move. One of the sliding frames 19 drives the other sliding frame 19 to move through the connecting rod 20. The sliding frame 19 drives the connecting block 14 to move into the fixing groove 9, so as to lock the position of the mounting block 6, which is convenient for installing and fixing the base 1, the vertical plate 3 and the triangular support plate 2, and the operation is convenient.
