A manual lubrication assembly is provided within the indexing head body. This assembly comprises a mounting box and a lubricant storage bladder. The mounting box is fixed to the inner wall of the indexing head body, and the lubricant storage bladder is placed within the mounting box. A drain pipe is connected to the end of the lubricant storage bladder, and the port of the drain pipe contacts the central shaft of the pneumatic indexing head. This pneumatic indexing head, through its equipped manual lubrication assembly, can lubricate the spindle to address wear, reducing friction during spindle rotation, ensuring reliable operation of the indexing head, and extending its service life. Furthermore, this manual lubrication assembly is easy to operate, requiring no professional personnel to activate the lubrication function.

[0004] When users use the above-mentioned patent, prolonged operation will cause deviation in the scale indication, affecting the indexing accuracy. The operator is prone to slipping when rotating, making operation laborious and inefficient. Furthermore, the workpiece is prone to slipping during the indexing rotation process, making it impossible to achieve uniform clamping of the workpiece and affecting the processing stability.

[0005] Therefore, a self-clamping indexing head is particularly needed. Utility Model Content

[0006] The purpose of this invention is to provide a self-clamping indexing head to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a self-clamping indexing head, comprising a supporting base assembly, a mating plate fixedly connected to the upper surface of the supporting base assembly, an indexing assembly mounted on the upper surface of the mating plate, and an indexing mechanism mounted on the side surface of the indexing assembly;

[0008] The indexing mechanism includes a scale operator assembly, which is mounted on the side of the indexing assembly.

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a self-clamping indexing head, including a supporting bottom shell assembly 1, a docking plate 2 fixedly connected to the upper surface of the supporting bottom shell assembly 1, an indexing assembly 4 installed on the upper surface of the docking plate 2, and an indexing mechanism 3 installed on the side surface of the indexing assembly 4.

[0025] The indexing mechanism 3 includes a scale operator assembly 301, which is mounted on the side of the indexer assembly 4. An adjusting sleeve 302 is fixedly connected to the side surface of the scale operator assembly 301. An adjusting insert 303 is inserted into the inner ring surface of the adjusting sleeve 302. A rocking handle 305 is fixedly connected to the bottom surface of the adjusting insert 303. A locking block 315 is fixedly connected to the side surface of the adjusting sleeve 302. A nut 316 is locked into the side surface of the locking block 315. A nut 316 is inserted into the inner ring surface of the nut 316. A threaded rod 317 is connected to a support plate 306 fixedly connected to one side of the bearing base assembly 1. A clamping collar 307 is fixedly connected to the upper surface of the support plate 306. A clamping limiting plate 308 is fixedly connected to the inner ring surface of the clamping collar 307. A telescopic rod 309 is inserted into the inner ring surface of the clamping limiting plate 308. A limiting guide rod 311 is inserted into the inner ring surface of the clamping limiting plate 308. A fixing limiting block 312 is fixedly connected to the bottom surface of the limiting guide rod 311. A docking assembly 313 is fixedly connected to one side of the indexer assembly 4.

[0026] Furthermore, a limiting socket 314 is provided on the inner ring surface of the adjusting sleeve 302, and the limiting socket 314 and the adjusting rod 303 are matched in size. The limiting socket 314 can precisely limit the insertion position of the adjusting rod 303, prevent the adjusting rod 303 from radially offset within the adjusting sleeve 302, ensure the stability of the adjusting rod 303 during axial movement, and thus ensure the accuracy during indexing operation, avoiding increased indexing error due to component shaking.

[0027] Furthermore, the bottom surface of the bearing base assembly 1 is provided with mounting openings 5, and there are multiple mounting openings 5. The multiple mounting openings 5 ​​are symmetrically distributed at the four corners of the bottom of the bearing base assembly 1, which facilitates the stable installation of the self-clamping indexing head on the worktable by means of bolts or other connecting parts.

[0028] Furthermore, a clamping plate 310 is fixedly connected to the upper surface of the telescopic rod 309, and the clamping plate 310 is connected to the clamping limit plate 308 through the telescopic rod 309. The clamping plate 310 adopts an arc-shaped structure design, and its surface is covered with anti-slip rubber pads. The arc-shaped structure can better fit the surface of the workpiece to be processed and increase the clamping contact area.

[0029] Furthermore, the nut 316 is connected to the adjusting sleeve rod 302 via the snap-fit ​​block 315, and the snap-fit ​​block 315 is symmetrically arranged vertically with the horizontal dividing line of the nut 316 as the axis of symmetry. The symmetrical snap-fit ​​blocks 315 can securely snap the nut 316 onto the adjusting sleeve rod 302, so that the nut 316 will not rotate when the threaded rod 317 rotates.

[0030] Furthermore, a guide block 304 is fixedly connected to one side of the adjusting rod 303, and the guide block 304 and the adjusting sleeve rod 302 are structurally matched. The guide block 304 cooperates with the guide groove on the inner wall of the adjusting sleeve rod 302, which can guide the movement direction of the adjusting rod 303, prevent the adjusting rod 303 from rotating in the adjusting sleeve rod 302, and ensure that the scale indication of the scale operator assembly 301 is accurate.

[0031] Furthermore, a knob handle 318 is fixedly connected to the side surface of the threaded rod 317, and the knob handle 318 is connected to the threaded rod 317 and the nut 316. The knob handle 318 is wrapped with rubber material and has anti-slip texture on the surface. The rubber material can improve the comfort of grip, and the anti-slip texture can increase the friction between the hand and the knob handle 318.

[0032] Working principle: When the user needs to use a self-clamping indexing head, the entire self-clamping indexing head is securely installed on the processing worktable through multiple mounting openings 5 ​​on the bottom surface of the bearing base assembly 1 using bolts and other connecting parts, ensuring that the equipment will not shift or shake during operation, providing a stable foundation for subsequent operations. The workpiece to be processed is docked with the docking assembly 313 fixedly connected to one side of the indexer assembly 4. The positioning structure of the docking assembly 313 achieves the initial position limitation of the workpiece, ensuring that the workpiece processing reference is aligned with the indexing center of the indexer assembly 4.

[0033] According to the size of the workpiece, adjust the telescopic rod 309, which is inserted into the inner ring of the clamping limit plate 308, so that the clamping plate 310, which is fixedly connected to the upper surface of the telescopic rod 309, fits against the surface of the workpiece. During the movement of the telescopic rod 309, the limiting guide rod 311, which is inserted into the inner ring of the clamping limit plate 308, plays a guiding role. Together with the bottom fixed limit block 312, it limits the position of the limiting guide rod 311, ensuring that the clamping plate 310 moves smoothly and finally achieves a firm clamping of the workpiece. The operator rotates the rocker arm, which is fixedly connected to the bottom surface of the adjusting rod 303. The handle 305 drives the adjusting rod 303 to move in the limiting socket 314 on the inner ring surface of the adjusting sleeve 302. The guide block 304 fixedly connected to one side of the adjusting rod 303 fits into the structure of the adjusting sleeve 302 to prevent the adjusting rod 303 from rotating and ensure that the scale operator assembly 301 can accurately display the scale and adjust the required scale parameter. When the scale parameter is adjusted to the target value, the knob handle 318 fixedly connected to the side surface of the threaded rod 317 is rotated to make the threaded rod 317 rotate on the inner ring surface of the nut 316.

[0034] Because the nut 316 is fixedly engaged by the locking block 315 on the side surface of the adjusting sleeve 302, the nut 316 can only move axially along the threaded rod 317, thereby pushing the adjusting sleeve 302 to drive the scale operator assembly 301 to fit tightly with the indexer assembly 4, thereby locking the indexing position and ensuring stable indexing accuracy during the processing. After the workpiece is processed, the indexing position is unlocked by rotating the knob handle 318 in the opposite direction, and the scale operator assembly 301 is reset by shaking the handle 305. Finally, the telescopic rod 309 is adjusted to loosen the clamping plate 310 from the workpiece, and the processed workpiece is removed, completing one complete processing cycle.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
