DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The utility model provides a positioning fixture for automobile parts processing, such as Figure 1-Figure 6 As shown, it includes a workbench 1 and a protective pad 4; a support frame 7 is arranged at the bottom end of the workbench 1, a positioning seat 2 is arranged at the top end of the workbench 1, and a bearing 3 is arranged at the top end of the positioning seat 2; a clamping structure 5 is arranged at the middle position of the positioning seat 2, and auxiliary structures 6 are arranged around the inside of the positioning seat 2.
[0024] Specifically, in this embodiment: when clamping the bearing 3, the bearing 3 is placed on the top of the positioning seat 2 and is sleeved on the outside of the clamping block 501 for pre-positioning. After the sleeve is completed, the bearing 3 is internally clamped by the setting of the clamping structure 5, so that the outer side of the bearing 3 has a better effect during polishing, and the setting of the auxiliary structure 6 can make the clamping block 501 more stable when moving.
[0025] In a further preferred embodiment of the present invention, Figure 1-Figure 6 As shown: the clamping structure 5 includes a clamping block 501, a fixed plate 502, a cylinder 503 and a top column 504, the fixed plate 502 is arranged at the bottom end of the workbench 1, the cylinder 503 is installed on the top of the fixed plate 502, the top column 504 is arranged on the top of the cylinder 503, the clamping block 501 is arranged at the top of the positioning seat 2, and a protective pad 4 is arranged on the outside of the clamping block 501. There are several clamping blocks 501, and the several clamping blocks 501 are distributed in a ring shape at the top of the positioning seat 2.
[0026] Specifically, in this embodiment: when clamping the bearing 3, the bearing 3 is placed on the top of the positioning seat 2. After placing it, the cylinder 503 is started. After starting, the cylinder 503 will drive the top column 504 to move upward. Since the bottom end of one side of the clamping block 501 is provided with a slope at a certain angle, the top column 504 will push the clamping block 501 to move outward when moving upward, thereby performing a positioning internal clamping on the bearing 3, and the protection pad 4 can be provided to protect the inner side of the bearing 3 to prevent the clamping block 501 from causing damage to the inner side of the bearing 3, thereby completing the clamping work.
[0027] In a further preferred embodiment of the present invention, Figure 1-Figure 6 As shown: the auxiliary structure 6 includes a guide groove 601, a return spring 602 and a guide block 603. The guide groove 601 is opened around the inside of the positioning seat 2. The guide block 603 is arranged inside the guide groove 601. The return spring 602 is arranged on one side of the guide block 603. The top of the guide block 603 is connected to the bottom end of the clamping block 501. There are several guide blocks 603, and the guide blocks 603 are symmetrically distributed inside the positioning seat 2. The side cross-sectional area of the guide groove 601 is larger than the side cross-sectional area of the guide block 603. A sliding connection is formed between the guide block 603 and the guide groove 601. The two sides of the return spring 602 are respectively connected to one side of the inside of the guide groove 601 and one side of the guide block 603. A telescopic structure is formed between the return spring 602 and the guide block 603.
