Description

Technical Field

[0001] This utility model relates to the technical field of gear production, specifically to a gear production support device. Background Technology

[0002] Gears are a very common type of workpiece. In the gear production process, most gear-bearing equipment cannot provide good stability and clamping accuracy, and some of the equipment cannot be well adapted to gears of various specifications. This leads to vibration during gear processing, causing gear displacement and deviation in the processing position, which affects gear quality and production efficiency. Therefore, we urgently need a gear production bearing device to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide a gear production support device that solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a gear production support device includes a base with a placement groove at its center. A drive motor is fixedly connected to the lower surface of the base, and a transmission rod is fixedly connected to the output end of the drive motor. The end of the transmission rod away from the drive motor extends upward into the placement groove. A rotating disk is disposed within the placement groove, and the rotating disk is fixedly connected to the transmission rod, contacting the inner wall of the placement groove. The left and right sides of the upper surface of the base are located outside the rotating disk. A U-shaped frame is fixedly connected to each side, and a second drive motor is fixedly connected to the U-shaped frame. A second transmission rod is provided inside the U-shaped frame, and one end of the second transmission rod is rotatably connected to a bearing in a bearing hole on the U-shaped frame. The other end of the second transmission rod is fixedly connected to the output end of the second drive motor. One end of a connecting rod is fixedly connected to the second transmission rod, and a limit plate is fixedly connected to the other end of the connecting rod. A first gasket is fixedly connected to the limit plate. A first hydraulic cylinder is fixedly connected to the upper surface of the base at the position corresponding to the connecting rod, and the output end of the first hydraulic cylinder is hinged to a connector on the connecting rod.

[0005] The base is fixedly connected to brackets on both the left and right sides, and a limiting adapter mechanism is fixedly connected to the brackets. The limiting adapter mechanism is used to limit the gear and adapt it to gears of different sizes.

[0006] Through the above technical solution, the connecting rod is moved by the drive motor 2. The drive motor 2 does not perform a complete rotation around the axis. With the support and stability provided by the hydraulic cylinder 1, the upper limit plate of the connecting rod initially limits the gear and is used to initially position the gear processing position.

[0007] Preferably, the limiting adapter mechanism includes a placement plate, which is fixedly connected to a bracket. Linear guide rails are fixedly connected to the opposite sides of the two placement plates, and driving blocks are slidably connected to the two linear guide rails. Extension rods are fixedly connected to the opposite sides of the two driving blocks. Straight rods are fixedly connected to the extension rods. A rotating plate is rotatably connected to the center of the bottom end of the straight rod through a bearing in a bearing hole. A rectangular plate is fixedly connected to the rotating plate. A limiting rod is fixedly connected to the bottom end of the rectangular plate. A limiter is fixedly connected to the rotating disk at the position corresponding to the limiting rod, and the limiting rod and the limiter are inserted into each other.

[0008] Through the above technical solution, this application utilizes a drive block on a linear guide rail to move downwards due to inconsistent gear sizes. A straight rod on the drive block moves downwards accordingly. The limiting rod at the bottom of the rectangular plate on the straight rod is inserted into the upper limit switch of the rotating disk for limiting. The straight rod is located at the center of the gear and is also used to position the gear.

[0009] Preferably, the rectangular plate has placement slots on all four sides, a hydraulic cylinder 2 is fixedly connected in the placement slot, and an arc-shaped plate is fixedly connected to the output end of the hydraulic cylinder 2, and a gasket 2 is fixedly connected to the arc-shaped plate.

[0010] Through the above technical solution, the arc plate is extended outward by the hydraulic cylinder 2, and the inner wall of the gear is contacted by the shim 2 to complete the adaptation of the inner diameter of the gear, thereby completing the limiting of the gear.

[0011] Preferably, a long plate is fixedly connected to the rectangular plate, a hydraulic cylinder three is fixedly connected to the lower surface of the long plate, a circular plate is fixedly connected to the output end of the hydraulic cylinder three, and a gasket three is fixedly connected to the circular plate.

[0012] Through the above technical solution, when the circular plate moves downward by the hydraulic cylinder three and comes into contact with the gear surface, the initially positioned limiting plate will be reset, and the circular plate driven by the hydraulic cylinder three will limit the gear.

[0013] Preferably, a mounting bracket is fixedly connected to the straight rod above the rectangular plate, and a vertical rod is hinged to the mounting bracket on the side away from the straight rod. A drive motor three is fixedly connected to the mounting bracket at the position of the vertical rod, and the drive motor three is fixedly connected to the vertical rod through a transmission rod three. A trapezoidal limiter is fixedly connected to the inner side of the vertical rod at the end away from the mounting bracket, and a silicone pad is fixedly connected to the trapezoidal limiter.

[0014] Through the above technical solution, since gear processing requires processing each gear tooth, when the gear teeth are being replaced, a trapezoidal limiter can be used to limit the gear teeth. When rotating, the trapezoidal limiter cancels the limit on the gear teeth. After the rotation stops, it limits the gear again. The silicone pad has a certain elasticity, so it can be adapted to the gear teeth of different sizes.

[0015] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0016] This gear production support device, through the design of a limiting and adapting mechanism, can improve the stability of the gear during the gear production process and enhance the tightness of the gear clamping. It effectively reduces vibrations during gear production and avoids gear misalignment caused by insecure clamping, thereby improving the efficiency and precision of gear production.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a gear production support device, including a base 1, a placement groove 2 at the center of the base 1, a drive motor 3 fixedly connected to the lower surface of the base 1, and a transmission rod 4 fixedly connected to the output end of the drive motor 3. The end of the transmission rod 4 away from the drive motor 3 extends upward into the placement groove 2. A rotating disk 5 is arranged in the placement groove 2, and the rotating disk 5 is fixedly connected to the transmission rod 4 and contacts the inner wall of the placement groove 2. U-shaped frames are fixedly connected to the left and right sides of the upper surface of the base 1 and outside the rotating disk 5. 6. A drive motor 7 is fixedly connected to the U-shaped frame 6. A transmission rod 8 is provided inside the U-shaped frame 6. One end of the transmission rod 8 is rotatably connected to the bearing in the bearing hole on the U-shaped frame 6. The other end of the transmission rod 8 is fixedly connected to the output end of the drive motor 7. One end of the connecting rod 9 is fixedly connected to the transmission rod 8. A limit plate 10 is fixedly connected to the other end of the connecting rod 9. A gasket 11 is fixedly connected to the limit plate 10. A hydraulic cylinder 12 is fixedly connected to the upper surface of the base 1 at the position corresponding to the connecting rod 9. The output end of the hydraulic cylinder 12 is hinged to the connector on the connecting rod 9.

[0028] The base 1 has brackets 13 fixedly connected to both the left and right sides, and a limit adapter mechanism 14 is fixedly connected to the brackets 13. The limit adapter mechanism 14 is used to limit the gear and adapt it to gears of different sizes.

[0029] Driven by the second drive motor 7, the connecting rod 9 is moved. The second drive motor 7 does not perform a complete rotation around the axis. With the support and stability provided by the first hydraulic cylinder 12, the upper limit plate 10 of the connecting rod 9 initially limits the gear 15, which is used to initially position the gear for machining.

[0030] The limiting adapter mechanism 14 includes a placement plate 141, which is fixedly connected to the bracket 13. Linear guide rails 142 are fixedly connected to the opposite sides of the two placement plates 141, and driving blocks 143 are slidably connected to the two linear guide rails 142. Extension rods 144 are fixedly connected to the opposite sides of the two driving blocks 143. Straight rods 145 are fixedly connected to the extension rods 144. A rotating plate 146 is rotatably connected to the center of the bottom end of the straight rod 145 through a bearing in the bearing hole. A rectangular plate 147 is fixedly connected to the rotating plate 146. A limiting rod 148 is fixedly connected to the bottom end of the rectangular plate 147. A limiter 149 is fixedly connected to the rotating disk 5 at the position corresponding to the limiting rod 148, and the limiting rod 148 and the limiter 149 are inserted into each other.

[0031] Because of the inconsistent gear sizes, this application uses a drive block 143 on a linear guide rail 142 to move downwards. A straight rod 145 on the drive block 143 moves downwards accordingly. The limiting rod 148 at the bottom of the rectangular plate 147 on the straight rod 145 is inserted into the upper limit device 149 of the rotating disk 5 for limiting. The straight rod 145 is located at the center of the gear 15 and is also used to position the gear 15.

[0032] The rectangular plate 147 has placement slots 1410 on all four sides. A hydraulic cylinder 1411 is fixedly connected in the placement slot 1410. An arc plate 1412 is fixedly connected to the output end of the hydraulic cylinder 1411. A gasket 1413 is fixedly connected to the arc plate 1412. In this application, the arc plate 1412 is extended outward by the hydraulic cylinder 1411 and contacts the inner wall of the gear 15 through the gasket 1413 to complete the adaptation of the inner diameter of the gear 15, thereby completing the limiting of the gear 15.

[0033] A long plate 1414 is fixedly connected to a rectangular plate 147. A hydraulic cylinder 1415 is fixedly connected to the lower surface of the long plate 1414. A circular plate 1416 is fixedly connected to the output end of the hydraulic cylinder 1415, and a gasket 1417 is fixedly connected to the circular plate 1416. In this application, when the circular plate 1416 moves downward through the hydraulic cylinder 1415 and contacts the surface of the gear 15, the initially positioned limiting plate 10 will be reset. The circular plate 1416 driven by the hydraulic cylinder 1415 limits the gear 15.

[0034] A mounting bracket 1418 is fixedly connected to the straight rod 145 above the rectangular plate 147. A vertical rod 1419 is hinged to the side of the mounting bracket 1418 away from the straight rod 145. A drive motor 1420 is fixedly connected to the mounting bracket 1418 at the position of the vertical rod 1419. The drive motor 1420 is fixedly connected to the vertical rod 1419 via a transmission rod 1421. A trapezoidal limiter 1421 is fixedly connected to the inner side of the end of the vertical rod 1419 away from the mounting bracket 1418. A silicone pad 1422 is fixedly connected to the limiter 1421. In this application, each tooth of the gear 15 needs to be processed. Therefore, when the gear 15 is being processed to replace the tooth, the trapezoidal limiter 1421 can limit the tooth of the gear 15. When rotating, the trapezoidal limiter 1421 cancels the limit on the tooth of the gear 15. After the rotation stops, it limits the gear 15 again. The silicone pad 1422 has a certain elasticity, so it can be adapted to the tooth of gears of different sizes.

[0035] When the gear production support device is in operation, the operator places the gear 15 on the rotating disk 5 on the base 1, and drives the connecting rod 9 on the transmission rod 8 to flip by controlling the output end of the drive motor 7. This causes the shim 11 on the limiting plate 10 to initially limit the position of the gear 15. The linear guide 142 on the mounting plate 141 on the bracket 13 drives the drive block 143 to move downward, so that the limiting rod 148 at the bottom of the rectangular plate 147 on the straight rod 145 connects with the upper limit device 149 on the rotating disk 5. The hydraulic cylinder 1411 on the rectangular plate 147 drives the arc plate 1412 outward and contacts and abuts against the inner wall of the gear 15. After the drive plate 1416 moves downward and contacts the gear 15, the limit plate 10 is reset under the drive of the drive motor 7. When the gear 15 is not rotating under the cooperation of the rotating disk 5 and the drive motor 3, the silicone pad 1422 on the trapezoidal limiter 1421 contacts the gear 5. The trapezoidal limiter 1421 is driven by the drive motor 1420 to complete the movement of the vertical rod 1419. When the gear 15 rotates on the rotating disk 5 and changes the gear teeth, the trapezoidal limiter 1421 cancels the clamping of the current gear teeth. After the gear 15 has finished rotating, the trapezoidal limiter 1421 clamps the new gear teeth after rotation.
