Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, specifically to an inner ring positioning mechanism for gear processing. Background Technology

[0002] Gears are mechanical components with teeth on their rims that can continuously mesh to transmit motion and power. During gear processing, gears need to be positioned and fixed. When dealing with edge burrs and surface treatments, inner ring positioning is used to position them, making them more stable during processing. When the production volume of gears is large, more positioning devices are needed. Currently, the positioning devices for gear inner rings are single-operation devices, with only one device placed for positioning at a time, resulting in reduced processing positioning efficiency. Utility Model Content

[0003] In order to solve the above problems, the purpose of this utility model is to provide an inner ring positioning mechanism for gear machining.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: an inner ring positioning mechanism for gear processing, comprising a placement plate, vertically arranged uprights fixed at the four corners of the lower surface of the placement plate, a horizontally arranged transverse plate fixed between the bottoms of the four uprights, a horizontally arranged movable plate between the transverse plate and the placement plate, vertically arranged positioning columns fixedly installed at the four corners of the upper surface of the movable plate, a connecting plate fixedly arranged between the bottoms of the positioning columns in a row, the top of the positioning column penetrating the placement plate and having a groove inside, a vertically arranged lead screw rotatably arranged in the groove, the two ends of the lead screw having opposite threads, sliders threaded into the two ends of the lead screw, four ring-shaped positioning plates arranged near the groove at the top of the positioning column, the side of the positioning plate facing the positioning column being movably inserted into the groove, and an adjusting rod hinged between the slider and the positioning plate;

[0005] The horizontal plate and the placement plate are connected by two symmetrically arranged screws that rotate together. The bottom of the two screws are connected by a belt that drives the movement. The moving plate is threaded onto the screws. A drive motor is fixedly installed on the lower surface of the horizontal plate near one of the screws. The output end of the drive motor is coaxially fixed on the screw.

[0006] Preferably, a support plate is fixedly provided on the outer wall of the positioning column below the groove, and a through groove corresponding to the support plate is opened on the upper surface of the placement plate.

[0007] Preferably, a rotating shaft is fixedly provided at the bottom of the lead screw, and the bottom of the rotating shaft is rotatably disposed within the connecting plate. A worm gear is fixedly provided at one end of the rotating shaft within the connecting plate, and a worm is meshed on the worm gear. A drive shaft is coaxially fixed among multiple worms, and the end of the drive shaft passes through the connecting plate and is fixedly provided with a rotating wheel.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. By setting multiple spaced positioning posts on the placement plate, workers can place multiple gears to be processed at once; and by simply rotating the rotating wheel at the bottom of the positioning post, the positioning plates at the top of multiple positioning posts can be driven to expand simultaneously, fully positioning the inner walls of multiple gears, avoiding the tediousness of single operation and greatly improving the efficiency of multi-gear positioning.

[0010] 2. During positioning, the worm gear, worm wheel, rotating shaft and lead screw are driven by the rotating wheel to expand and position the positioning plate. After processing, the rotating wheel can be rotated in the opposite direction to move the positioning plate away from the gear and quickly cancel the positioning. The operation is simple and convenient and easy for the staff to master.

[0011] 3. Start the drive motor to rotate the screw, which will cause the moving plate to move the positioning column and support plate down to the bottom of the placement plate, allowing the gear to be directly disengaged from the positioning column. This makes it easy for workers to quickly remove the gear without any additional complicated operations, and facilitates the collection and transportation of the processed gear, improving the convenience of subsequent processing.

[0019] 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.

[0020] Example: Figure 1-5 As shown, this utility model provides an inner ring positioning mechanism for gear processing, including a placement plate 1. Vertically arranged uprights 11 are fixed at the four corners of the lower surface of the placement plate 1. A horizontally arranged horizontal plate 12 is fixed between the bottoms of the four uprights 11. A horizontally arranged movable plate 14 is provided between the horizontal plate 12 and the placement plate 1. Vertically arranged positioning posts 15 are fixedly installed at the four corners of the upper surface of the movable plate 14. A connecting plate 22 is fixed between the bottoms of the positioning posts 15 in a row. The top of the positioning post 15 penetrates the placement plate 1 and has a groove 16 inside. A vertically arranged lead screw 17 is rotatably arranged in the groove 16. The two ends of the lead screw 17 have opposite threads. Slider blocks 18 are threaded into the two ends of the lead screw 17. Four positioning plates 2 are arranged in a ring near the groove 16 at the top of the positioning post 15. The side of the positioning plate 2 facing the positioning post 15 is movably inserted into the groove 16. An adjusting rod 19 is hinged between the slider 18 and the positioning plate 2.

[0021] Two symmetrically arranged screws 3 are provided for the horizontal plate 12 and the placement plate 1 to rotate together. The bottom of the two screws 3 are connected by a belt 31 for transmission. Specifically, a synchronous pulley is installed at the bottom between the two screws 3. The two synchronous pulleys are connected by the belt 31 for transmission. The synchronous pulley and the synchronous belt are toothed to eliminate the lag in the transmission between the two screws 3. The moving plate 14 is threaded into the screw 3. A drive motor 32 is fixedly installed on the lower surface of the horizontal plate 12 near one of the screws 3. The output end of the drive motor 32 is coaxially fixed on the screw 3.

[0022] A support plate 23 is fixedly installed on the outer wall of the positioning post 15 below the groove 16. A through groove 24 corresponding to the support plate 23 is opened on the upper surface of the placement plate 1. The support plate 23 can support the gear to be processed inserted into the positioning post 15, so that its bottom has sufficient support, which can facilitate the positioning operation of the gear in conjunction with the positioning plate 2. At the same time, the through groove 24 makes it convenient for the positioning post 15 to leave the gear directly after it moves down with the moving plate 14, so that the subsequent workers can directly remove the processed gear and improve the operation efficiency.

[0023] Movable rods 21 are fixedly provided at the upper and lower ends of the side of the positioning plate 2 facing the positioning post 15. The movable rods 21 are movably inserted into the groove 16. The movable rods 21 can provide support for the horizontal movement of the positioning plate 2 when the adjusting rod 19 pushes the positioning plate 2 to move, so that it can move stably and prevent deviation.

[0024] A rotating shaft 26 is fixedly installed at the bottom of the lead screw 17. The bottom of the rotating shaft 26 is rotatably mounted inside the connecting plate 22. A worm gear 27 is fixedly installed at one end of the rotating shaft 26 inside the connecting plate 22. A worm 28 is meshed on the worm gear 27. A drive shaft 29 is coaxially fixed among multiple worms 28. The end of the drive shaft 29 passes through the connecting plate 22 and is fixedly mounted with a rotating wheel 291. The rotating wheel 291 can directly drive the worm 28 and the worm gear 27 to rotate simultaneously. This allows multiple rotating shafts 26 to be driven to rotate at the same time, which facilitates the operator to complete the purpose of controlling the positioning plates 2 on multiple positioning columns 15 to perform inner ring positioning of the gears at one time, improving the operating efficiency. Furthermore, the self-locking property of the worm gear 27 and worm 28 is used for driving, which increases the stability after driving.

[0025] Vertically positioned limiting rods 33 are movably inserted at the four corners of the movable plate 14. The upper and lower ends of the limiting rods 33 are fixedly mounted on the placement plate 1 and the horizontal plate 12, respectively. The limiting rods 33 are mainly used to ensure the stable up-and-down movement of the movable plate 14 and to prevent it from shifting when driven by the screw 3, thus affecting the normal up-and-down movement of the movable plate 14.

[0026] Support feet 13 are fixedly installed at the four corners of the lower surface of the horizontal plate 12. Shock-absorbing rubber pads are installed at the bottom of the support feet 13. The support feet 13 and the shock-absorbing rubber pads at the bottom are mainly for providing sufficient support and stability for the device above and reducing the impact of vibration generated during processing.

[0027] Working principle: In use, the operator places the gear to be positioned onto the top of the positioning post 15. Multiple positioning posts 15 are spaced apart on the placement plate 1, allowing the operator to place multiple gears to be processed at once. After the gear is positioned on the top of the positioning post 15 and its bottom abuts against the support plate 23, the operator can rotate the rotating wheel 291 at the bottom of the positioning post 15. The rotating wheel 291 drives the worm gear 28 to rotate, which in turn drives the meshing worm wheel 27. Therefore, the worm wheel 27 drives the fixed rotating shaft 26 to rotate, causing the rotating shaft 26 to drive the top... When the lead screw 17 rotates, the sliders 18 threaded at both ends of the lead screw 17 will move towards each other simultaneously. As a result, the adjusting rod 19, which is hinged between the sliders 18 and the positioning plate 2, will gradually move to a horizontal state. At this time, the adjusting rod 19 will push the positioning plate 2 away from the positioning post 15, causing the positioning plates 2, which are arranged in a ring around the positioning post 15, to expand simultaneously and position the inner wall of the gear. Through the above operation, it is only necessary to drive the rotating wheel 291 to control the expansion of the positioning plates 2 on the top of multiple positioning posts 15 to fully position the gear, which greatly improves the efficiency of positioning multiple gears.

[0028] After the above operations are completed and the positioning is achieved, the processing operation is carried out. After the processing operation is completed, the operator can rotate the rotating wheel 291 in the opposite direction to control the positioning plate 2 away from the gear, thereby directly canceling the positioning of the gear. Then the drive motor 32 starts and drives the screw 3 to rotate, causing the moving plate 14 with the thread inserted on the screw 3 to move down at the same time. At this time, the moving plate 14 will drive the positioning column 15 and the support plate 23 to move below the placement plate 1. At this time, the gear will directly disengage from the positioning column 15, making it convenient for the operator to quickly remove the gear for direct collection and transportation.
