[0025] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 1-Figure 14 As shown, the auxiliary rotation positioning device of the utility model comprises a base 1, a positioning block 2, a bearing 3, a bottom plate 4, a latch 5, a cover plate 6, and a support body 7.

[0027] The base 1 is a square plate welded on top of another square plate, and the two square plates are in a vertical relationship. There is a large through hole in the middle of the vertical square plate, and there are 4 positioning pin holes and 6 countersunk positioning holes on the horizontal square plate.

[0028] The positioning block 2 is a wheel disc with a protrusion in the middle and threaded holes and pin holes on the protrusion plane, and the protrusion outer diameter is connected to the bearing 3.

[0029] The bearing 3 is a standard deep groove ball bearing 60000 type 6410. The bearing 3 needs to be installed on the base 1 and the positioning plate 2 to play a connecting role and ensure the stable rotation of the positioning block 2.

[0030] The bottom plate 4 is a disc with multiple positioning pin holes, which is connected to the positioning plate 2. The positioning pin holes ensure that the workpiece is stably positioned during clamping.

[0031] The latch 5 is fixed on the bottom plate 4, connecting the positioning block 2 and the bottom plate 4

[0032] The cover plate 6 is composed of a stud, a pressure plate and a nut. The structure of the nut is an external hexagonal structure, which is convenient for disassembly and assembly. There is a hole in the center and a thread on the inside of the hole. The shoulder can increase the contact area with the pressure plate. The pressure plate is a frustum body with an avoidance hole in the center, which contacts the inner arc diameter of the workpiece. The stud is a 130mm long cylinder with M16 external threads on both ends. It is connected to the base plate 4 through the stud. The nut and the stud are screwed together to make the pressure plate move to the left, and the workpiece is clamped firmly by squeezing.

[0033] The support body 7 has two positioning holes and three threaded holes at the bottom to ensure the correct installation position. The bearings are installed symmetrically on both sides. In order to avoid the bearings, grooves with a depth of 20 and a width of 6.5 are opened on both sides. The entire support body 7 is arc-shaped in the middle to avoid the workpiece loading being stuck due to the protrusion in the middle.

[0034] Connection relationship:

[0035] Install the two supports 7 onto the upper plane of the base 1, use cylindrical pins to position and tighten with screws. Put the bearing 3 onto the middle protrusion of the positioning block 2, and put the whole into the middle hole of the vertical plate of the base 1. Connect the concave hole of the base plate 4 with the boss of the positioning block 2, insert the cylindrical pin into the pin hole and use screws to pre-tighten, check the surface of the base plate 4 to observe whether the verticality meets the requirements within 0.02. If qualified, screw in the screws to ensure tightening, and continue to check to ensure verticality; if unqualified, readjust the base plate 4 and continue the above steps. Screw the stud into the center thread of the base plate 4, put the pressure plate on the stud, and screw the nut into the top of the stud. Rotate the positioning block 2 so that the pin 5 can be smoothly installed in the pin holes of the base plate 4 and the base 1.

[0036] The method of using the auxiliary rotary positioning device is as follows: place the whole on the machine tool platform, use the pressure plate to pre-tighten the three notches of the base 1, use the meter to align the whole device, and press the pressure plate. Remove the cover plate 6, place the workpiece on the support body 7, rotate the workpiece so that the positioning pin is aligned with the workpiece positioning hole, screw in the cover plate 6, ensure that the positioning pin enters the workpiece, and tighten the workpiece to separate from the support body 7.

[0037] Rotate the positioning block 2 so that the pin 5 can be smoothly inserted into the pin holes of the bottom plate 4 and the base 1. After processing this angle, the positioning block 2 can be rotated further to insert the pins at the 90° and 120° positions to ensure that the workpiece is rotated to a specific angle. After processing is completed, remove the cover plate 6 and place the workpiece on the support body 7 to prevent the workpiece from falling directly.

[0038] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make several modifications and improvements without departing from the principle of the present invention, and these modifications and improvements should also be considered to belong to the protection scope of the present invention.
