Description

Technical Field

[0001] This utility model relates to the field of gear manufacturing technology, specifically to a gear manufacturing tooling fixture. Background Technology

[0002] Gears are key components in mechanical transmissions used to transmit motion and power, achieving rotational motion or torque transmission through the meshing of gear teeth. Their core structure consists of teeth, tooth grooves, and pitch circles. Based on tooth profile, they can be classified into spur, helical, and herringbone types. Gear drives offer advantages such as high efficiency, precise transmission ratios, and compact structure, and are widely used in automotive transmissions, machine tool spindles, industrial robots, and other fields.

[0003] In gear manufacturing, factors such as cutting force and gravity can cause gears to shift or deform. Especially for high-precision gears, even small shifts or deformations can affect their transmission performance. In order to effectively control these errors, it is necessary to apply a uniform clamping force to the gears using a fixture to improve machining accuracy and stability.

[0004] To address this, a gear manufacturing tooling fixture is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a gear manufacturing tooling fixture to solve the problem of gear deformation caused by displacement during the processing of gears.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A gear manufacturing tooling fixture includes a worktable, with support legs fixedly connected to all four sides of the bottom of the worktable, a fixed frame fixedly connected to the rear top of the worktable, a hydraulic rod inside the fixed frame, a fixed plate fixedly connected to the output end of the hydraulic rod, a clamping rod mirror-arranged on the top of the worktable, a placement block fixedly connected to the output end of the clamping rod, compression springs fixedly connected to the upper and lower ends inside the placement block, a movable plate fixedly connected to the output end of the compression springs, a clamping assembly on the top of the worktable, and a rotating assembly on the top of the worktable.

[0008] Furthermore, the clamping assembly includes a fixed frame disposed on the front side of the fixed plate, a hydraulic rod II fixedly connected to the rear side of the fixed frame, a crossbar fixedly connected to the output end of the hydraulic rod II, movable frames movably connected to the left and right ends of the crossbar, connecting seats fixedly connected to the upper and lower ends of the movable frames, a linkage rod I hinged between the connecting seats and the fixed frame, a rectangular hole opened on the output end of the fixed frame, a sliding plate movably connected inside the rectangular hole, and a linkage rod II hinged between the connecting seat and the sliding plate.

[0009] Furthermore, the shape and volume of the crossbar are adapted to the interior of the movable frame.

[0010] Furthermore, the shape and volume of the slide plate are adapted to the interior of the rectangular hole.

[0011] Furthermore, the rotating assembly includes a rotating shaft movably connected inside the fixed plate, a gear fixedly connected to the rear side of the rotating shaft, a rectangular slot opened on the rear side of the fixed plate, a hydraulic rod three fixedly connected to the left side of the rectangular slot, a connecting rod fixedly connected to the output end of the hydraulic rod three, and a toothed plate fixedly connected to the output end of the connecting rod.

[0012] Furthermore, the top of the workbench is provided with a placement slot, and a dust collection frame is provided inside the placement slot. The left and right sides of the dust collection frame are fixedly connected with fixed seats, and screws are threadedly connected between the fixed seats and the workbench. Hooks are fixedly connected to the top of the fixed seats.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model first uses a clamping assembly to drive the clamping rod to clamp the gear on both sides, so that the gear will not be displaced during the manufacturing process. The tension of the compression spring drives the movable plate to abut against the wall of the gear, so that the movable plate can clamp gears of different thicknesses. The rotating assembly drives the clamping rod to rotate, so that the gear can be processed at multiple angles.

[0015] 2. This utility model, through the setting of the clamping component, activates the hydraulic rod two, which pushes the crossbar forward through its output end. During the movement of the crossbar, the movable frame and the connecting seat move forward. When the connecting seat moves forward, it pushes the linkage rod two to move, causing the linkage rod two to move towards each other with the connecting seat as the center. Then, the linkage rod two drives the slide plate to move inside the rectangular hole. The slide plate moves towards each other, realizing that the slide plate drives the clamping rod and the placement block to clamp the gear, which facilitates the subsequent processing of the gear and avoids the problem of deformation caused by displacement.

[0026] like Figures 1 to 5As shown, a gear manufacturing tooling fixture includes a worktable 1. Support legs 2 are fixedly connected to all four sides of the bottom of the worktable 1. A fixed frame 3 is fixedly connected to the rear top of the worktable 1. A hydraulic rod 301 is installed inside the fixed frame 3. A fixed plate 302 is fixedly connected to the output end of the hydraulic rod 301. A clamping rod 303 is mirror-arranged on the top of the worktable 1. A placement block 304 is fixedly connected to the output end of the clamping rod 303. Compression springs 305 are fixedly connected to the upper and lower ends inside the placement block 304. A movable plate 306 is fixedly connected to the output end of the compression spring 305. A clamping assembly 4 for driving the clamping rod 303 to clamp a gear 502 is installed on the top of the worktable 1. A rotating assembly 5 for driving the clamping rod 303 to rotate is installed on the top of the worktable 1.

[0027] It should be noted that, firstly, the clamping assembly 4 drives the clamping rod 303 to clamp the gear 502 on both sides, so that the gear 502 will not be displaced during the manufacturing process. The tension of the compression spring 305 drives the movable plate 306 to abut against the wall of the gear 502, so that the movable plate 306 can clamp gears 502 of different thicknesses. The rotating assembly 5 drives the clamping rod 303 to rotate, so that the gear 502 can be processed at multiple angles.

[0028] The clamping assembly 4 includes a fixed frame 401 disposed on the front side of the fixed plate 302. A hydraulic rod 402 is fixedly connected to the rear side of the fixed frame 401. A horizontal crossbar 403 is fixedly connected to the output end of the hydraulic rod 402. A movable frame 404 is movably connected to the left and right ends of the crossbar 403. A connecting seat 405 is fixedly connected to the upper and lower ends of the movable frame 404. A linkage rod 406 is hinged between the bottom connecting seat 405 and the fixed frame 401. A rectangular hole 407 is opened on the side of the fixed frame 401 where the output ends are close to each other. A sliding plate 408 is movably connected inside the rectangular hole 407. The output ends of the sliding plate 408 are fixedly connected to the side of the clamping rod 303 that is far away from each other. A linkage rod 409 is hinged between the top connecting seat 405 and the sliding plate 408.

[0029] It should be noted that when hydraulic rod 402 is activated, it pushes crossbar 403 forward through its output end. During the movement of crossbar 403, it drives movable frame 404 and connecting seat 405 forward. When connecting seat 405 moves forward, it pushes linkage rod 409 to move, causing linkage rod 409 to move towards each other with the connecting seat 405 as the center. Then, linkage rod 409 drives slide plate 408 to move inside rectangular hole 407. Slide plate 408 moves towards each other, so that slide plate 408 drives clamping rod 303 and placement block 304 to clamp gear 502, which facilitates subsequent processing of gear 502 and avoids deformation caused by displacement.

[0030] The rotating assembly 5 includes a rotating shaft 501 movably connected inside the fixed plate 302. The front side of the rotating shaft 501 is fixedly connected to the rear side of the fixed frame 401. A gear 502 is fixedly connected to the rear side of the rotating shaft 501. A rectangular groove 503 is provided on the rear side of the fixed plate 302. A hydraulic rod 504 is fixedly connected to the left side of the rectangular groove 503. A connecting rod 505 is fixedly connected to the side wall of the output end of the hydraulic rod 504. A toothed plate 506 is fixedly connected to the output end of the connecting rod 505.

[0031] It should be noted that when the hydraulic rod 504 is started, it drives the connecting rod 505 to move left or right through the output end. During the movement, the connecting rod 505 drives the toothed plate 506 to move left or right at the bottom of the gear 502, which in turn drives the gear 502 to rotate in the forward or reverse direction. This causes the gear 502 to rotate through the rotating shaft 501 and the clamping assembly 4, thereby realizing multi-directional processing of the gear 502.

[0032] The top of the workbench 1 is provided with a placement slot 6, and a dust collection frame 601 is provided inside the placement slot 6. Fixing seats 602 are fixedly connected to the left and right sides of the dust collection frame 601. Screws 603 are threadedly connected between the fixing seats 602 and the workbench 1. Hooks 604 are fixedly connected to the top of the fixing seats 602.

[0033] It should be noted that the debris generated during the manufacturing process of gear 502 falls into the interior of the dust collection frame 601. By rotating the screw 603 in the opposite direction and then using the hook 604, the dust collection frame 601 can be removed from the interior of the placement slot 6, and the debris inside the dust collection frame 601 can be poured out, thereby achieving the cleaning of the debris.

[0034] In summary: First, the clamping assembly 4 drives the clamping rod 303 to clamp the gear 502 on both sides, ensuring that the gear 502 will not shift during manufacturing. The tension of the compression spring 305 drives the movable plate 306 to abut against the wall of the gear 502, allowing the movable plate 306 to clamp gears 502 of different thicknesses. The rotating assembly 5 drives the clamping rod 303 to rotate, enabling multi-angle processing of the gear 502.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
