Description

TECHNICAL FIELD

[0001] The utility model relates to stator processing equipment field, especially a novel material grabbing clamping jaw. BACKGROUND

[0002] In the processing equipment of the stator, the clamping and transfer of the stator is one of the key factors of automatic processing. However, some existing stators are small in size, and the clamping jaw adopting the profiling structure often has the problem of inaccuracy in clamping caused by sliding. At the same time, the existing profiling clamping jaw also has the problem of limited applicability.

[0003] For example, Chinese patent CN202323054098.2 mainly adopts an outer clamping structure, thus having limitations and poor applicability. At the same time, with the development of existing stators, the outer peripheral wall is not limited to a circular shape, thus increasing the requirements for the clamping jaw. SUMMARY

[0004] The main purpose of the utility model is to provide a novel material grabbing clamping jaw, aiming to improve the existing clamping jaw structure, realize two clamping modes of internal support and external expansion, replace the clamping rod according to different products, and have simple and compact structure and strong applicability.

[0005] To achieve the above purpose, the utility model provides a novel material grabbing clamping jaw, comprising:

[0006] A driving device is provided with two oppositely arranged driving blocks;

[0007] A clamping rod is detachably installed on the driving block, the clamping rod comprises a clamping section, and the driving device can drive the two clamping rods to move between the position close to each other and the position far away from each other.

[0008] In actual design, when different products are used, even if the driving device is large in size, the clamping rod can also be provided with a smaller diameter, so that the clamping rod can be conveniently inserted into the hollow cavity of the stator and expanded outward, thereby realizing internal clamping. At the same time, through the arrangement of the clamping section, the turns spacing of the outer wall of the stator can be clamped, thereby realizing stable external clamping.

[0009] Thus, the applicability and versatility of the clamping jaw are improved, and the lower limit is that the maximum outer diameter of the two clamping rods close to each other is smaller than the inner diameter of the hollow cavity, so that external expansion can be realized, thereby realizing internal clamping.

[0022] As shown in the figure, a new type of material grabbing clamp jaw comprises: Figs. 1 to 4

[0023] ​The driving device 1 is provided with two driving blocks 10 arranged oppositely;

[0024] The clamping rod 2 is detachably installed on the driving block 10, and the clamping rod 2 comprises a clamping section 2a,

[0025] The driving device 1 can drive the two clamping rods 2 to move between the close position and the far position.

[0026] In actual design, even if the driving device 1 is large in size, the clamping rod 2 can be arranged to be small in diameter when different products are used, so that the clamping rod 2 can be extended into and expanded outward from the hollow cavity of the stator 100, thereby realizing internal clamping; at the same time, the clamping section 2a can clamp the inter-turn spacing of the outer wall of the stator 100, thereby realizing stable external clamping.

[0027] Thus, the applicability and universality of the clamping jaw are improved, and the lower limit is that the maximum outer diameter of the two clamping rods 2 when they are close to each other is smaller than the inner diameter of the hollow cavity, so that the clamping rod 2 can be expanded outward, thereby realizing internal clamping.

[0028] Specifically, the cross section of the clamping section 2a is triangular or quadrangular, and of course the clamping section 2a is not limited to be flat, so that the clamping area can be set according to the actual product, thereby improving the clamping stability.

[0029] In the embodiment of the utility model, the clamping section 2a is provided with at least one edge type part 20 or imitation type part, and according to actual design, the clamping section 2a can also be a non-standard part, for example, a convex edge type part 20 or imitation type part is arranged, which ensures the stability of clamping while not affecting the outer diameter.

[0030] Specifically, the edge type part 20 is 30-90 degrees, so that it can be clamped into the spacing 200 between the two turns.

[0031] In the embodiment of the utility model, the driving block 10 is provided with a slot 31, the clamping rod 2 is provided with a plug rod 32 inserted into the slot 31, and the plug rod can be detachably installed in the slot 31.

[0032] Specifically, the plug rod is provided with a vertical wall 3a (which can make the edge type part face according to the predetermined setting), and the side wall of the driving block 10 is provided with a pin hole 3b provided with a pin, and the end of the pin is in abutment with the vertical wall 3a, so that the position of the clamping rod 2 can be corrected and fixed, and of course specific screw connection, buckle connection and other modes can also be used.

[0033] In the embodiment of the utility model, the upper section of the clamping section 2a is provided with a boss 2b, the outer diameter of the boss 2b is greater than the maximum outer diameter of the clamping section 2a, wherein the boss 2b can play the role of positioning and supporting, for example, when inverted, the position of the boss 2b away from the arc-shaped part can limit the end wall of the stator 100, and can also realize the role of position positioning.

[0034] Specifically, the boss 2b is gradually reduced in diameter from bottom to top, thereby forming an arc-shaped structure, so that when it extends into the hollow cavity, the problem of interference or collision damage can be reduced.

[0035] In the embodiment of the utility model, the wall surface of the boss 2b close to the clamping section 2a is a horizontal wall 21.

[0036] Specifically, the driving device 1 is a bidirectional clamping motor or a bidirectional clamping air cylinder, which can make the structure smaller, wherein the bidirectional clamping device can also be provided with a guide rail and a sliding block, for example, the driving block 10 is installed on the sliding block.
