Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a jig for machining a worm seat. Background Technique

[0002] A worm seat is a mechanical transmission device, usually used to convert rotational motion into linear motion or change the direction of motion. It mainly consists of a worm wheel and a worm. The worm wheel is a disc similar in shape to a helix, with a thread-like groove on its surface called a spiral curve. The worm is a cylinder similar to a screw rod, and its surface also has spiral protrusions that cooperate with the spiral curve of the worm wheel. When the worm rotates, the worm wheel will move along the spiral curve, thereby achieving the effect of converting rotational motion into linear motion or changing the direction of motion. During processing, a jig is required to fix it.

[0003] After retrieval, the text of the patent number "CN220659975U" mentions that "the utility model discloses a jig for machining a hydraulic valve block, including a support plate, a support rod and an adjustment assembly. The support plate is symmetrically provided with support rods. One group of the support rods is fixedly connected to the support plate, and an adjustment assembly is provided on the other group of support rods; the adjustment assembly includes a connecting shaft, a worm, a first rotating rod, a connecting column and a worm wheel. The connecting shaft is rotatably connected inside the other group of support rods. One end of the connecting shaft is provided with a worm. The connecting shaft is rotatably connected inside the other group of support rods. The connecting column is provided with a worm wheel. Through the provided adjustment assembly, the hydraulic valve block clamped by the clamping block is flipped and adjusted. Rotating the first rotating rod drives the worm to rotate. When the worm rotates, it drives the worm wheel to rotate, drives a group of strip plates to rotate, and cooperates with the rotation of the other group of strip plates to flip and process the clamped hydraulic valve block, which is convenient for processing different parts of the hydraulic valve block." When in use, through the provided adjustment assembly, the hydraulic valve block clamped by the clamping block is flipped and adjusted. Rotating the first rotating rod drives the worm to rotate. When the worm rotates, it drives the worm wheel to rotate, drives a group of strip plates to rotate, and cooperates with the rotation of the other group of strip plates to flip and process the clamped hydraulic valve block, which is convenient for processing different parts of the hydraulic valve block. However, the structure providing support for the components after clamping of this device is less, and the clamping directions provided are fewer. When the components are being processed, there is a situation where the components are deflected by the processing tools, which easily causes a decrease in processing accuracy.

[0025] The clamping mechanism 2 includes a pressure-bearing component 21, an adjusting component 22, an upper pressing component 23, a side pressing component 24, and a control component 25. A pressure-bearing component 21 is installed on one side of the main body 1. An adjusting component 22 is installed at the top of the pressure-bearing component 21.

The lower friction pad 212 is adhesively connected to the surface of the bottom plate 211. The bottom plate 211 provides support for the bottom of the processing element, and the lower friction pad 212 increases friction.

[0027] Further, the adjusting component 22 includes an adjusting screw 221 and a limiting block 222. The adjusting screw 221 is rotatably connected to the top of the bottom plate 211.

When in use, in the first step, connect the mounting plate 42 with the processing device through screws, place the element on the bottom plate 211 and fit it with the lower friction pad 212. In the second step, rotate the adjusting screw 221 to control the upper pressing plate 231 to press down, so that the upper friction pad 232 and the lower friction pad 212 are in contact, clamping the element and increasing the friction force at the same time. The limiting block 222 maintains the displacement direction of the upper pressing plate 231 perpendicular. In the third step, rotate the control gear 253 to drive the transmission gear 251 to rotate through the transmission rod 252, and the engaged front L-shaped toothed rod 241 and rear L-shaped toothed rod 242 follow the displacement to provide side clamping for the element. After clamping, press the control gear 253 to fit with the surface groove on the upper surface of the main body 1 to complete the limit and prevent the clamping from falling off.
