Description

Technical Field

[0001] This utility model belongs to the field of worm gear machining positioning technology, specifically a positioning device for worm gear machining. Background Technology

[0002] A worm gear is a gear with one or more helical teeth that meshes with a worm wheel to form an interlocking gear pair. Its pitch surface can be cylindrical, conical, or toroidal. There are four types: Archimedean worm, involute worm, normal straight profile worm, and conical envelope cylindrical worm. During the production process, the surface of the worm gear needs to be polished and ground.

[0003] Since different worm gears have different sizes and specifications, the single positioning device in the current technology cannot meet the needs of worm gears of various sizes. Therefore, it is necessary to replace the positioning device. However, this process increases the number of steps in worm gear processing, thereby reducing processing efficiency.

[0004] Therefore, this utility model provides a positioning device for worm gear machining. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A positioning device for worm gear machining, comprising a worktable; multiple supports are fixedly connected to the top of the worktable; a top plate is fixedly connected to the top of each support; a guide rail is fixedly connected to the middle of the top plate; a slider is slidably connected to the outer side of the guide rail; a cylinder is fixedly connected to the bottom of the slider; a clamping block is fixedly connected to the bottom of the cylinder; and an adjustment component is provided in the middle of the clamping block. During operation, the relative position between the clamping blocks is adjusted according to the length of the worm gear. First, the guide rail is activated, driving the slider to move, changing the distance between the sliders, and thus adjusting... The distance between the clamping blocks is adjusted, and then the cylinder is activated. The cylinder changes the position of the clamping blocks on the worktable to a height that facilitates the worker's machining of the worm gear. The worm gear is then placed into the clamping blocks, and the adjusting component adjusts the clamping degree of the clamping blocks according to the size of the worm gear to achieve a reinforced clamping effect. The worm gear is then machined. After machining is completed, the worm gear is removed, and after the guide rail and cylinder are activated, the clamping blocks are reset. By setting the guide rail in conjunction with the cylinder, the position of the clamping blocks can be adjusted so that the clamping blocks can be used to clamp and fix worm gears of different lengths in the appropriate position, meeting the needs of various worm gear machining applications and speeding up the worm gear machining process.

[0007] Preferably, the adjustment assembly includes slide rods disposed on both sides of the clamping block. The slide rods are slidably connected to the clamping block. A pressure block is fixedly connected to one end of the slide rod. A spring is sleeved on the outside of the slide rod. One end of the spring is fixedly connected to the pressure block, and the other end of the spring is fixedly connected to the clamping block. A handle is fixedly connected to the other end of the slide rod. During operation, when the worm gear is placed in the middle of the clamping block, the handle is first grasped and pulled outward. The slide rod slides inside the clamping block, causing the spring to compress. The pressure block moves towards the edge of the clamping block, leaving a gap in the middle of the pressure block. Then, the worm gear is placed in the middle of the pressure block. The handle is then released, and the pressure block returns to its original position under the action of the spring, further positioning and fixing the worm gear. By setting the spring to apply elastic force to the pressure block, the pressure block applies pressure to the worm gear, allowing the slide rod to slide inside the clamping block. This expands the adjustment range of the pressure block, enabling the pressure block to further clamp and fix worm gears of different sizes.

[0008] Preferably, the top plate has two air guide pipes on one side, which are fixedly connected to the worktable. The top of the air guide pipe is connected to an external air pipe, and one side of the air guide pipe is connected to multiple air holes. During operation, the external air pipe is connected to an air pump, and the gas is stored in the air guide pipe. After the worm is installed in the clamping block, the external air pipe releases gas to clean the surface of the worm. During the processing, the debris generated during the processing of the worm is cleaned to reduce the debris adhering to the worm for subsequent storage.

[0009] Preferably, a guide plate is provided on the other side of the top plate. The guide plate is inclined and one end is fixedly connected to the workbench. A collection trough is provided on one side of the guide plate. The collection trough is opened on the surface of the workbench. During operation, the debris generated by the worm gear machining is guided by the airflow blown out by the external air pipe to float towards the guide plate. Under the guidance of the guide plate, the debris falls into the collection trough. The collection trough collects the debris for subsequent centralized processing.

[0010] Preferably, a pad is provided in the middle of the pressure block, and the pad is fixedly connected to the pressure block. During operation, the pressure block clamps the worm gear, and the pad increases the friction between the worm gear and the worm gear, reducing the phenomenon of slippage between the worm gear and the pressure block, and reducing the impact on the processing steps.

[0011] Preferably, a baffle is provided on one side of the bracket, one end of the baffle is fixedly connected to the guide plate, and the bottom of the baffle is fixedly connected to the worktable. During operation, the baffle blocks the two sides of the worktable, reducing the amount of debris flying off the worktable surface and making it easier to clean.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The positioning device for worm gear machining described in this utility model, by setting a guide rail and cooperating with a cylinder, realizes the position adjustment of the clamping block so that the clamping block can be used to clamp and fix worm gears of different lengths in a suitable position, meet the use needs of various worm gear machining, and speed up the worm gear machining process.

[0014] 2. The positioning device for worm gear processing described in this utility model uses a spring to apply elastic force to the pressure block, thereby enabling the pressure block to press the worm gear. The slide bar can slide within the clamping block, thus expanding the adjustment range of the pressure block and allowing the pressure block to further clamp and fix worm gears of different sizes.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5As shown in the embodiment of this utility model, a positioning device for worm gear machining includes a worktable 1.

A cylinder 15 is fixedly connected to the bottom of the slider 14. A clamping block 16 is fixedly connected to the bottom of the cylinder 15. An adjustment component is provided in the middle of the clamping block 16. During operation, the relative position between the clamping blocks 16 is adjusted according to the length of the worm gear. First, the guide rail 13 is activated, causing the slider 14 to move, changing the distance between the sliders 14, and thus adjusting the clamping block 16. The distance between 6 is adjusted, and then cylinder 15 is activated. Cylinder 15 changes the position of clamping block 16 on worktable 1 to a height that facilitates the worker's machining of the worm gear. The worm gear is then placed into clamping block 16, and the adjusting component adjusts the clamping degree of clamping block 16 according to the size of the worm gear to achieve a reinforced clamping effect. The worm gear is then machined. After machining is completed, the worm gear is removed, and after the guide rail 13 and cylinder 15 are activated, the clamping block 16 is reset. By setting the guide rail 13 in conjunction with cylinder 15, the position of clamping block 16 can be adjusted so that clamping block 16 can be used to clamp and fix worm gears of different lengths in a suitable position, meeting the needs of various worm gear machining and speeding up the worm gear machining process.

[0024] like Figures 2 to 3 As shown, the adjustment assembly includes slide rods 2 disposed on both sides of the clamping block 16. The slide rods 2 are slidably connected to the clamping block 16. A pressure block 21 is fixedly connected to one end of the slide rod 2. A spring 22 is sleeved on the outside of the slide rod 2. One end of the spring 22 is fixedly connected to the pressure block 21, and the other end of the spring 22 is fixedly connected to the clamping block 16. A handle 23 is fixedly connected to the other end of the slide rod 2. During operation, when the worm gear is placed in the middle of the clamping block 16, the handle 23 is first grasped and pulled outward, causing the slide rod 2 to slide within the clamping block 16. The spring 22 is compressed, and the pressure block 21 moves towards the edge of the clamping block 16, leaving a gap in the middle of the pressure block 21. Then, the worm is placed in the middle of the pressure block 21, and the handle 23 is released. Under the action of the spring 22, the pressure block 21 returns to its original position and further positions and fixes the worm. By setting the spring 22 to apply elastic force to the pressure block 21, the pressure block 21 applies pressure to the worm, and the slide bar 2 can slide within the clamping block 16, thereby expanding the adjustment range of the pressure block 21 and enabling the pressure block 21 to further clamp and fix worms of different sizes.

[0025] like Figures 1 to 4As shown, two air guide pipes 3 are provided on one side of the top plate 12. The air guide pipes 3 are fixedly connected to the worktable 1. An external air pipe 31 is connected to the top of the air guide pipe 3. Multiple air holes 32 are connected to one side of the air guide pipe 3. During operation, the external air pipe 31 is connected to an air pump. The gas is stored in the air guide pipe 3. After the worm is installed in the clamping block 16, the external air pipe 31 releases gas to clean the surface of the worm. During the processing, the debris generated during the processing of the worm is cleaned to reduce the debris adhering to the worm for subsequent storage.

[0026] like Figures 1 to 5 As shown, a guide plate 4 is provided on the other side of the top plate 12. The guide plate 4 is inclined and one end of the guide plate 4 is fixedly connected to the workbench 1. A collection groove 41 is provided on one side of the guide plate 4. The collection groove 41 is opened on the surface of the workbench 1. During operation, the debris generated by the worm gear machining is guided by the airflow blown out by the external air pipe 31 and floats towards the guide plate 4. Under the guidance of the guide plate 4, the debris falls into the collection groove 41. The collection groove 41 collects the debris for subsequent centralized processing.

[0027] like Figure 3 As shown, a pad 5 is provided in the middle of the pressure block 21. The pad 5 is fixedly connected to the pressure block 21. During operation, the pressure block 21 clamps the worm gear. The pad 5 increases the friction between the worm gear and the pressure block 21, reducing the phenomenon of the worm gear sliding with the pressure block 21 and reducing the impact on the processing steps.

[0028] like Figures 1 to 5 As shown, a baffle 6 is provided on one side of the bracket 11. One end of the baffle 6 is fixedly connected to the guide plate 4, and the bottom of the baffle 6 is fixedly connected to the workbench 1. During operation, the baffle 6 blocks the two sides of the workbench 1 to reduce the amount of debris flying off the surface of the workbench 1 and making it inconvenient to clean.

[0029] Working principle: The relative position of the clamping blocks 16 is adjusted according to the length of the worm gear. First, the guide rail 13 is activated, driving the slider 14 to move, changing the distance between the sliders 14, and thus adjusting the distance between the clamping blocks 16. Next, the cylinder 15 is activated, changing the position of the clamping blocks 16 on the worktable 1 to a height suitable for machining the worm gear. The worm gear is then placed into the clamping blocks 16, and the adjusting assembly adjusts the clamping degree of the clamping blocks 16 according to the worm gear's dimensions, achieving a reinforced clamping effect. The worm gear is then machined. After machining, the worm gear is removed, and the guide rail... After the guide rail 13 and cylinder 15 are started, they drive the clamping block 16 to reset. By setting the guide rail 13 in conjunction with the cylinder 15, the position of the clamping block 16 can be adjusted so that the clamping block 16 can be used to clamp and fix worms of different lengths in a suitable position, meeting the needs of various worm machining applications and speeding up the worm machining process. When the worm is placed in the middle of the clamping block 16, first grasp the handle 23 and pull the handle 23 outward. The slide rod 2 slides in the clamping block 16, driving the spring 22 to compress. The pressure block 21 moves towards the edge of the clamping block 16, leaving a gap in the middle of the pressure block 21. Then, the worm is placed in the pressure block 21. Then, release the handle 23. Under the action of the spring 22, the pressure block 21 returns to its original position and further positions and fixes the worm. By setting the spring 22 to apply elastic force to the pressure block 21, the pressure block 21 applies pressure to the worm, and the slide bar 2 can slide within the clamping block 16, thereby expanding the adjustment range of the pressure block 21, so that the pressure block 21 can further clamp and fix worms of different sizes. The external air pipe 31 is connected to the air pump, and the gas is stored in the air guide pipe 3. After the worm is installed in the clamping block 16, the external air pipe 31 releases gas to clean the surface of the worm. During the processing, the worm... The processing debris is cleaned to reduce its adhesion to the worm gear, which would make subsequent storage inconvenient. The debris generated during worm gear processing is guided by the airflow from the external air pipe 31 to the guide plate 4. Under the guidance of the guide plate 4, the debris falls into the collection tank 41, which collects the debris for subsequent centralized processing. The pressure block 21 clamps the worm gear, and the pad block 5 increases the friction between the worm gear and the pressure block 21, reducing the phenomenon of slippage between the worm gear and the pressure block 21 and minimizing the impact on the processing steps. The baffle 6 separates the two sides of the worktable 1, reducing the debris flying off the surface of the worktable 1 and making cleaning inconvenient.
