Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to a gear processing grabbing fixture. Background Art

[0002] According to the search of China Invention Publication No.: CN218964261U, a gear processing grabbing fixture is disclosed, including a mounting disc, a support plate is fixed to the inner wall of the mounting disc, a motor is installed above the support plate, and an output shaft is arranged in the middle of the motor, a first gear is fixed to the outside of the output shaft, a second gear is arranged on the side of the first gear, and a turntable is fixed to the outside of the second gear, a positioning ring is installed at the bottom of the turntable, and a third gear is fixed to the outside of the turntable, and a fourth gear is arranged on the side of the third gear, and a threaded rod is fixed in the middle of the fourth gear. The utility model facilitates the simultaneous control of multiple clamps to move and clamp the processing gears through the cooperation of parts such as the motor, the first gear and the threaded rod, thereby reducing the difficulty of operating the equipment and increasing the work efficiency. At the same time, the clamp and the mounting plate are fixedly connected by fixing bolts, which facilitates the disassembly and replacement of the clamp and the clamping of gears of different specifications.

[0003] However, when implementing the above technical scheme, the following problems exist: the above scheme can realize the position fixation of gears of different sizes on the surface of the device by the splint and the replacement of the splint, but the movement synchronization and position fixation of the splint in the scheme are difficult to ensure that the surface of the splint is in contact with the protruding surface or concave surface of the gear to achieve fixation in three directions. The surface of the gear has protruding restrictions and recessed grooves, and the two are arranged regularly. The splint needs to contact the three surfaces of the gear at the same time to achieve stable position fixation, but it is difficult to ensure that the splint can contact the protruding or recessed surfaces at the same time. Since the splint can only move synchronously, there may be a single surface or double-sided splint that does not contact the gear surface. At this time, the fixing effect of the gear is poor, and it is necessary to continuously adjust the internal gear adaptation device and conduct multiple tests, which is relatively cumbersome. For this reason, the utility model provides a gear processing grasping fixture. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a gear processing grabbing fixture, which solves the problems that the clamping plate of the gear processing grabbing fixture needs to be synchronously moved in position to contact and fix with the gear surface, the position of the gear to be processed needs to be constantly adjusted to ensure that the clamping plate is in contact with the three surfaces at the same time, and the gear position needs to be constantly tested during clamping to ensure the clamping effect, which is a cumbersome process.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a gear processing gripping fixture, including a gear processing table, an internal rotating clamping block of the gear processing table, a fixing mechanism is arranged between the gear processing table and the clamping block to fix the position of the gear, and the fixing mechanism includes:

The slidable clamping rod inside the clamping block can be moved by the rotation and thread of the action rod. When the action bevel wheel and the synchronous bevel wheel surface are meshed, the three clamping rods will move synchronously toward the center of the clamping block. When the bevel wheel surface is separated, the action rod can be rotated alone to control the position of the clamping rod, so as to ensure that the gear surface within the size range will contact the clamping rods on three sides, thereby ensuring the clamping effect.

[0016] (2) The gear processing grabbing fixture is provided with a cylindrical rotating column on the surface of the clamping block, and a semicircular protruding clamping block is provided on the sliding surface of the gear processing table. The surface of the clamping block is brought into contact with the surface of the rotating column by the movement of the clamping block, and the rotation column is restricted from moving again by an arc, thereby achieving the purpose of limiting the angle of the clamping block relative to the gear processing table. The sliding of the clamping block can be achieved by simply pressing a push rod, which is simple to operate and convenient for quickly controlling the structural position.

[0030] Embodiment 2

[0031] The main difference from the first embodiment is:

[0032] A gear processing grabbing fixture, the moving component 5 includes a moving shaft 51 fixed on the surface of the clamping rod 41, a moving groove 52 is opened inside the clamping block 2, and the surface of the moving shaft 51 is slidably connected to the inner surface of the moving groove 52, the sliding component 6 includes a sliding shaft 61 fixed on the surface of the action cone wheel 43, the surface of the action rod 42 is opened with a sliding groove 62, the surface of the sliding shaft 61 is slidably connected to the inner surface of the sliding groove 62, the thread length on the surface of the action rod 42 is limited, and there is no intersection between the thread position and the sliding groove 62, the operating component 7 includes an operating rod 71 that slides inside the clamping block 2, the surface of the operating rod 71 has a columnar protrusion, the surface of the action cone wheel 43 is opened with an operating groove 72, and the surface of the columnar protrusion on the surface of the operating rod 71 is slidably connected to the inner surface of the operating groove 72, the rotating component 8 includes a card block 81 that slides inside the gear processing table 1, the surface of the clamping block 2 is fixed and rotated The surface of the locking block 81 can contact the surface of the rotating column 82 by sliding.

The pressing assembly 83 includes a pressing rod 831 that slides with the inside of the gear processing table 1. An oblique groove 832 is provided on the surface of the locking block 81. The surface of the pressing rod 831 is slidably connected with the inner surface of the oblique groove 832. A cylindrical rotating column is arranged on the surface of the locking block 81.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0034] When working, first adjust the angle of the clamping block 2 relative to the gear processing table 1 according to the size of the gear to be processed and the distribution of the surface teeth, pull the pressing rod 831 upwards, and then pull the rotating column 82 to drive the clamping block 2 to rotate.

If the positions need to be changed separately, slide the operating rod 71, and the operating rod 71 pulls the action cone wheel 43 to slide on the surface of the action rod 42 through the operating groove 72. The surface of the action cone wheel 43 is separated from the surface of the synchronous cone wheel 44, and a single movement can be achieved. When moving uniformly, start the cylinder 45, and the cylinder 45 pushes the action rod 42 to slide, thereby driving the action rod 42 to rotate.
