Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to a gear processing fixture. Background Technology

[0002] Some machined gears need to have holes or slots made in them to meet the needs of special applications. Before making holes in the gears, they need to be fixed in place.

[0003] Existing gear fixing fixtures often use pressure plates and other components to press the gear onto the worktable at the top of the gear. This fixing method requires measuring the gear fixing position first, and then using pressure plates to tighten it. However, during the drilling operation, the pressure plates on both sides can easily interfere with equipment such as drilling machines. Furthermore, if the initial measurement is inaccurate, tightening can easily cause inaccurate drilling later, which has an adverse effect on the convenience of gear processing. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a gear machining fixture.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gear machining fixture includes a fixed platform and a cylinder. The fixed platform is a circular mechanism with a hollow cavity inside. A cylinder is fixedly connected to the center of the top of the fixed platform. Four hollow windows are opened around the top of the cylinder outside the hollow cavity. Each hollow window has a sliding groove symmetrically opened at the top and bottom. A slider is slidably connected in the sliding groove. An arc-shaped top block is fixedly connected between every two opposing sliders. Each arc-shaped top block has an inclined thread on the side near the center of the cylinder. A rotating column is slidably connected to the center of the cylinder. A flat-topped cone located at the top of the hollow window is fixedly connected to the top of the rotating column. A support base is fixedly connected to the center of the bottom of the hollow cavity. The bottom of the rotating column is slidably connected to the center hole of the support base.

[0007] Preferably, the fixed platform is fixedly installed on the base, and a telescopic column is fixedly installed on the top of one side of the base, and a drilling machine is fixedly installed on the top of the telescopic end of the telescopic column.

[0008] Preferably, the top of the fixed platform is provided with several slots that are not connected to the hollow cavity. A processing gear is placed at the top of the slot, and the center of the processing gear is fitted around the outer ring of the cylinder.

[0009] Preferably, a limit block is provided at one end of the slide near the outer ring of the cylinder, and four movable grooves adapted to the slider are opened at the center of the top of the fixed platform.

[0010] Preferably, the outer ring of the flat-top cone has a threaded groove that engages with the inclined thread, and the thickness of the flat-top cone is less than the thickness of the arc-shaped top block.

[0011] Preferably, the outer wall of the bottom of the rotating column is provided with four vertical grooves evenly distributed. A driven gear is rotatably connected to the top of the support base and sleeved on the outer wall of the rotating column. The inner ring of the driven gear is fixedly connected with four fixed blocks that are slidably connected to the four vertical grooves.

[0012] Preferably, a motor is fixedly mounted on the top of the support base via a bracket, and the output shaft of the motor is fixedly connected to a drive gear that meshes with the driven gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model features a fixed platform and a cylinder. The fixed platform is used to place the gear being processed, and the center of the gear is placed on the outside of the cylinder. The slots facilitate drilling operations by a drilling machine, and the gear can be placed directly on the outer ring of the cylinder without the need for manual measurement and fixing.

[0015] This invention integrates the centering and fixing functions of the gear by setting up arc-shaped top blocks and flat-top cones. The four arc-shaped top blocks apply forces synchronously to the inner ring of the gear, and the four arc-shaped top blocks are moved away from or closer to each other by rotating columns and flat-top cones that can be rotated and raised. Compared with the traditional method of fixing the position by manual measurement and pressure plate clamping, the measurement step is eliminated, reducing the problem of inaccurate drilling caused by measurement errors. Furthermore, the method of fixing the inner ring of the gear effectively reduces interference with drilling machines or other processing equipment. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6 A gear processing fixture includes a fixed platform 1 and a cylinder 9. The fixed platform 1 is a circular mechanism with a hollow cavity 7 inside. The cylinder 9 is fixedly connected to the center of the top of the fixed platform 1. Four hollow windows 10 are opened around the top of the cylinder 9 outside the hollow cavity 7. Each hollow window 10 has a sliding groove 11 symmetrically opened at the top and bottom. A slider 12 is slidably connected in the sliding groove 11. An arc-shaped top block 13 is fixedly connected between every two opposing sliders 12. An inclined thread 14 is opened on the side of each arc-shaped top block 13 near the center of the cylinder 9. A rotating column 15 is slidably connected to the center of the cylinder 9. A flat-top cone 16 located at the top of the hollow window 10 is fixedly connected to the top of the rotating column 15. A support base 8 is fixedly connected to the center of the bottom of the hollow cavity 7. The bottom of the rotating column 15 is slidably connected to the center hole of the support base 8. The fixed platform 1 is used to place the gear 6 being processed. The center of the gear 6 is fitted onto the outside of the cylinder 9, and the inner ring of the gear 6 is simultaneously subjected to force by four arc-shaped top blocks 13, thus achieving the functions of centering and fixing the gear 6 in one unit. The four arc-shaped top blocks 13 can be moved away from or closer to each other by a rotating column 15 that can be rotated and raised, and a flat-topped cone 16.

[0025] As a technical optimization of this utility model, the fixed platform 1 is fixedly installed on the base 2, and a telescopic column 3 is fixedly installed on the top of one side of the base 2. A drilling machine 4 is fixedly installed on the top of the telescopic end of the telescopic column 3. The drilling machine 4 is used for drilling the gear 6, and the height of the drilling machine 4 can be adjusted by the telescopic column 3.

[0026] As a technical optimization of this utility model, the top of the fixed platform 1 is evenly provided with several slots 5. The slots 5 are not connected to the hollow cavity 7. A processing gear 6 is placed at the top of the slot 5, and the center of the processing gear 6 is fitted around the outer ring of the cylinder 9. The slots 5 facilitate drilling operations by the drilling machine 4, and the processing gear 6 can be directly placed on the outer ring of the cylinder 9 without the need for manual measurement and fixing.

[0027] As a technical optimization of this utility model, a limiting block is provided at one end of the slide groove 11 near the outer ring of the cylinder 9, and four movable grooves adapted to the slider 12 are opened at the center of the top of the fixed platform 1. The limiting block is used to restrict the movement position of the slider 12, and the movable grooves provide sliding space for the slider 12 when the arc-shaped top block 13 slides out of the hollow window 10 to fix the processing gear 6, so that the arc-shaped top block 13 slides stably and can also ensure the stable fixation of the arc-shaped top block 13 on the processing gear 6.

[0028] As a technical optimization of this utility model, the outer ring of the flat-top cone 16 is provided with a threaded groove that meshes with the inclined thread 14. The thickness of the flat-top cone 16 is less than the thickness of the arc-shaped top block 13. The threaded groove and the inclined thread 14 not only mesh with each other, but also form a rotational connection through the form of an embedded groove. This ensures that while the flat-top cone 16 and the inclined thread 14 rotate relative to each other, it can automatically descend vertically. Furthermore, when the motor 20 reverses, the flat-top cone 16 rises vertically, which can drive the four arc-shaped top blocks 13 to move closer to each other and reset.

[0029] As a technical optimization of this utility model, four vertical grooves 17 are evenly provided on the outer wall of the bottom of the rotating column 15. A driven gear 18, which is rotatably connected to the top of the support base 8, is sleeved on the outer wall of the rotating column 15. Four fixing blocks 19, which are slidably connected to the inner ring of the driven gear 18, are fixedly connected to the four vertical grooves 17. The cooperation between the vertical grooves 17 and the fixing blocks 19 allows the rotating column 15 to be rotated by the driven gear 18, and also allows the rotating column 15 to be raised and lowered through the vertical grooves 17.

[0030] As a technical optimization of this utility model, a motor 20 is fixedly installed on the top of the support base 8 by a bracket. The output shaft of the motor 20 is fixedly connected to a drive gear 21 that meshes with the driven gear 18. The motor 20 is used to drive the drive gear 21 to rotate, thereby driving the driven gear 18 to rotate in both directions to realize the lifting and lowering of the rotating column 15 and the flat-top cone 16.

[0031] In use, the machining gear 6 to be drilled is first placed on the top of the fixed platform 1, and the center of the machining gear 6 is inserted into the top of the cylinder 9. At this time, the control motor 20 rotates, driving the drive gear 21 to rotate, so that the driven gear 18 rotates synchronously. Through the drive of the fixed block 19, the rotating column 15 rotates, and the flat-topped cone 16 also rotates synchronously. At this time, the threaded groove of the flat-topped cone 16 rotates relative to the inclined threads 14 of the four arc-shaped top blocks 13, so that the flat-topped cone 16 moves downward along the inclined threads 14. During this period, the rotating column 15 moves downward and slides along the center hole of the support base 8, while the height position of the driven gear 18 remains unchanged, but the vertical groove 1... As the fixed block 19 descends, the flat-top cone 16 moves downward, and the larger diameter end of the top of the flat-top cone 16 pushes the four arc-shaped top blocks 13 to gradually slide along the slide groove 11 through the slider 12 and move away from each other. Finally, the side walls of the four arc-shaped top blocks 13 abut against the inner ring of the processing gear 6, thus centering and positioning the processing gear 6 simultaneously. After fixing the processing gear 6, the drilling machine 4 is controlled to perform drilling operations. After drilling is completed, the motor 20 reverses, causing the rotating column 15 and the flat-top cone 16 to rotate and rise, driving the four arc-shaped top blocks 13 to reset along the slide groove 11 towards the center of the hollow window 10. The processing gear 6 can then be removed and another processing gear 6 can be replaced, repeating the above fixing and drilling operations.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
