[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example

[0021] Please see Figure 1-3This embodiment provides the following technical solution: a positioning fixture for a main reducer housing, including a base 1, the base 1 being fixedly connected to the workbench of a processing equipment, a support frame 2 being fixedly connected to the base 1, and a plurality of clamping mechanisms being fixedly connected to the support frame 2 for positioning the workpiece. In some embodiments, two clamping mechanisms are provided, and the two clamping mechanisms are fixedly connected side by side to the support frame 2.

[0022] In some embodiments, the support frame 2 includes two mounting plates, which are symmetrically arranged on the base 1 at intervals, and one end of the mounting plate is fixedly connected to the base 1.

[0023] The clamping mechanism includes two support plates 3, which are symmetrically arranged on the support frame 2 at intervals. Each support plate 3 has a positioning groove 4 on one side facing the other. A positioning pin 5 is fixedly connected to one side of the support plate 3 located in the positioning groove 4. Locking pressure plates 6 are provided on both sides of the positioning pin 5. After the workpiece is aligned and positioned by the positioning pin 5 and the locking pressure plates 6, the workpiece can be locked and fixed to ensure that the workpiece is clamped tightly and does not loosen, thereby improving the positioning accuracy, processing effect and production efficiency of the workpiece.

[0024] In some embodiments, locking plates 6 are disposed on the upper and lower sides of the positioning pin 5. After the pin hole on the workpiece corresponds to the positioning pin 5 on the support plate 3, the two locking plates 6 rotate simultaneously in the direction of the positioning pin 5, so that the two locking plates 6 press and fix the workpiece. With the cooperation of the four locking plates 6 on the two support plates 3, the workpiece is pressed and fixed as a whole, ensuring that the workpiece is clamped and does not loosen.

[0025] Multiple positioning blocks 7 are fixedly connected to the support plate 3 on the front side of the positioning groove 4. The multiple positioning blocks 7 are arranged in a ring on the support plate 3 with the positioning groove 4 as the center. The multiple positioning blocks 7 cooperate to form the support surface of the workpiece. After the pin hole on the workpiece is aligned with the positioning pin 5, the workpiece can be pressed tightly against the positioning block 7.

[0026] The locking plate 6 is mounted on the support plate 3 via an adjustment mechanism. The adjustment mechanism includes an adjustment screw 8, one end of which is threaded onto the support plate 3, and the other end of which passes through the locking plate 6 and is threaded onto a locking nut 9. A fixing nut 10 is threaded onto the other end of the adjustment screw 8 located on the locking plate 6. By adjusting the distance of the fixing nut 10 on the adjustment screw 8, the distance between the locking plate 6 and the support plate 3 can be adjusted. After the locking plate 6 has been adjusted, the locking nut 9 can be threaded onto the adjustment screw 8, so that the locking nut 9 and the fixing nut 10 work together to support and fix the locking plate 6.

[0027] The locking plate 6 is provided with an adjustment groove 11 for the adjustment screw 8 to move. In some embodiments, the adjustment groove 11 is provided along the length direction of the locking plate 6. The specific position of the locking plate 6 on the adjustment screw 8 can be adjusted according to the specifications of the workpiece, which is beneficial to make the locking plate 6 press more effectively on the surface of the workpiece.

[0028] A limiting screw 12 is threadedly connected to one side of the adjusting screw 8 on the support plate 3 to limit the locking plate 6. In some embodiments, the two limiting screws 12 are distributed vertically on the support plate 3, while the two adjusting screws are located between the two limiting screws 12. By setting the limiting screws 12, the angle at which the locking plate 6 flips outward can be limited, which is beneficial for dragging the locking plate 6 to press and fix the workpiece.

[0029] The two positioning pins 5 and four positioning blocks 7 on the two support plates 3 cooperate with each other.

[0030] The working principle of this utility model is as follows: When in use, move the workpiece so that the pin hole on the workpiece is aligned with the positioning pin 5 on the support plate 3, and insert the workpiece into the positioning pin 5. At this time, the surface of the workpiece is in close contact with the positioning block 7 on the support plate 3. Then, rotate the locking plate 6 on each adjusting screw 8 so that the four locking plates 6 rotate toward the workpiece at the same time until the locking plates 6 are pressed against the surface of the workpiece. Then, rotate the locking nut 9 to fix the position of the locking plate 6.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
