Description

Technical Field

[0001] This utility model relates to the field of spiral bevel gear processing, specifically a fixture for spiral bevel gear processing. Background Technology

[0002] Spiral bevel gears, also known as spiral conical gears, are commonly used for motion and power transmission between two intersecting shafts. The teeth of a bevel gear are distributed on the surface of a cone, with the tooth profile gradually decreasing from the large end to the small end. Spiral bevel gears require clamping during machining.

[0003] Patent application CN202022383648.5 discloses a fixing fixture for the production of stainless steel bevel gears, belonging to the field of fixing fixtures. It includes a base, support columns, a ferrule, a hydraulic rod, a clamping head, upper clamping teeth, lower clamping teeth, and a connecting plate. Support columns are installed at both ends of the base. Several upper clamping teeth are provided on the left and right sides of the support column surface. A ferrule is fitted onto the support column, and pull rings are provided on both the left and right sides of the ferrule's exterior. This invention features a first fixed shaft, a second fixed shaft, and a third fixed shaft to accommodate bevel gears of different bore diameters, expanding its application range and reducing industrial costs. The upper and lower clamping teeth allow the ferrule to move up and down on the support column for easy adjustment.

[0004] However, in practical applications, traditional clamps require the workpiece to be initially positioned before the position of the clamping mechanism can be adjusted to clamp and fix the spiral bevel gear. This makes the clamping and fixing steps numerous and complicated, reduces the convenience of clamping, and affects the overall processing efficiency. For example, when clamping a spiral bevel gear for water intake, it needs to be placed on a fixed shaft. A suitable fixed shaft needs to be selected, and then the position of the clamping mechanism needs to be adjusted so that the clamping mechanism is located on the outside of the spiral bevel gear. This makes the clamping process complicated and reduces the convenience of clamping. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a fixture for machining spiral bevel gears, so as to solve the technical problems of numerous and complicated clamping and fixing steps, which reduce the convenience of clamping and affect the overall processing efficiency.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a fixture for processing spiral bevel gears is designed, including a base plate, an L-shaped frame is uniformly fixed on the top of the base plate, a first mounting plate is fixed on the inner side of the L-shaped frame, a support rod is uniformly fixed on the top of the first mounting plate, a second mounting plate is fixed on the top of the support rod, a clamping mechanism is connected between the first mounting plate and the second mounting plate; a limit mechanism is provided on the top of the base plate.

[0007] In this solution, by setting up a clamping mechanism, the spiral bevel gear is placed on the outside of the L-shaped rod and directly fixed by the clamping mechanism, avoiding the need to adjust the position of the clamping mechanism. The clamping and fixing steps are simple, improving the convenience of clamping and avoiding affecting the overall processing efficiency. By setting up a limit mechanism, the clamping mechanism is limited to prevent loosening and ensure the stability of clamping.

[0008] Preferably, the clamping mechanism includes a screw that rotates through the top center of the first mounting plate, a movable ring screwed to the outer wall of the screw, mounting seats evenly fixed to the outer wall of the movable ring, a connecting rod rotating inside the mounting seat, movable slots evenly opened through the tops of the first mounting plate and the second mounting plate, movable plates connected inside the upper and lower movable slots, an L-shaped rod connected to the top of the movable plates, a connecting seat fixed to the bottom of one side of the movable plates, and a turntable fixed to the bottom end of the screw.

[0009] In practical applications, by fitting the spiral bevel gear onto the outside of the L-shaped rod, rotating the turntable drives the screw to rotate, causing the moving ring to descend, which in turn lowers the mounting base. This causes the connecting rod to deflect horizontally, moving the moving plate and thus the L-shaped rod. This clamps and secures the inner side of the spiral bevel gear, eliminating the need to adjust the clamping position, reducing clamping steps, simplifying the clamping and securing process, improving clamping convenience, and avoiding impacting overall processing efficiency.

[0010] Preferably, the clamping mechanism further includes limiting grooves formed in the middle of both sides of the bottom moving groove, and limiting blocks are fixed at the bottom of both sides of the moving plate.

[0011] In practical applications, when the moving plate moves, the limiting block and the limiting groove are used to limit the moving plate, so that the moving plate moves stably inside the moving groove.

[0012] Preferably, the limiting block slides inside the limiting groove, and the outer sidewall of the limiting block is in contact with the inner sidewall of the limiting groove.

[0013] Preferably, one end of the connecting rod rotates inside the connecting seat, and the two sides of the moving plate are in contact with the two sides of the moving groove.

[0014] In practical applications, when the moving ring descends, the mounting base descends, causing the connecting rod to deflect, which in turn moves the connecting base, thereby moving the moving plate.

[0015] Preferably, the limiting mechanism includes a fastening bolt that is threaded through and screwed to the top edge of the first mounting plate, a mounting ring fixed to the outer side wall of the turntable, limiting teeth evenly fixed to the outer side wall of the mounting ring, a housing fixed to the top edge of the base plate, a locking block sliding inside the housing, a pull rod fixed to the middle of one side of the locking block, and a return spring fixed to one side of the locking block.

[0016] In practical applications, when the turntable rotates, it drives the mounting ring to move, causing the limit teeth to deflect and press against the inclined surface of the clamping block. This compresses the return spring. When the limit teeth separate from the clamping block, the return spring resets the clamping block, thus blocking the limit teeth and preventing the turntable from rotating. Then, the fastening bolt is rotated to press against the turntable, further securing the turntable and preventing it from loosening. This ensures the stability of the clamped workpiece, avoids loosening, and improves processing quality.

[0017] Preferably, one end of the locking block is provided with an inclined surface, one end of the return spring is fixed to one side of the inner cavity of the housing, and the return spring is sleeved on the outside of the pull rod, and the pull rod slides through the middle of one side of the housing.

[0018] In practical applications, when the limit tooth deflects, it facilitates the squeezing of the inclined surface of the locking block, causing the locking block to move and squeezing the return spring. When the limit tooth separates from the locking block, the locking block is reset by the reset spring.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the setting of a clamping mechanism, connects the spiral bevel gear to the outside of the L-shaped rod. Rotating the turntable drives the screw to rotate, causing the moving ring to descend, which in turn lowers the mounting base. This causes the connecting rod to deflect horizontally, moving the moving plate and thus the L-shaped rod. This clamps and fixes the inner side of the spiral bevel gear, avoiding the need to adjust the clamping position, reducing the clamping steps, simplifying the clamping and fixing process, improving the convenience of clamping, and avoiding affecting the overall processing efficiency.

[0020] 2. This utility model, through the setting of a limiting mechanism, drives the mounting ring to move when the turntable rotates, thereby causing the limiting teeth to deflect and squeeze the inclined surface of the clamping block, thus compressing the return spring. When the limiting teeth separate from the clamping block, the clamping block is reset by the reset spring, thereby blocking the limiting teeth and preventing the turntable from rotating. Then, the fastening bolt is rotated to make the fastening bolt press against the turntable, further securing the turntable and preventing it from loosening, ensuring the stability of the clamped workpiece, preventing loosening, and improving the processing quality.

A limiting mechanism 7 is provided on the top of the base plate 1. By setting the clamping mechanism 6, the spiral bevel gear is placed on the outside of the L-shaped rod 607 and directly fixed by the clamping mechanism 6, avoiding the need to adjust the position of the clamping mechanism 6. The clamping and fixing steps are simple, improving the convenience of clamping and avoiding affecting the overall processing efficiency. The limiting mechanism 7 is used to limit the clamping mechanism 6 to prevent loosening and ensure the stability of clamping.

[0024] For details, see Figure 2 and Figure 3The clamping mechanism 6 includes a screw 601 that rotates through the top center of the first mounting plate 3. A movable ring 602 is screwed to the outer wall of the screw 601. Mounting seats 603 are evenly fixed to the outer wall of the movable ring 602. A connecting rod 604 rotates inside the mounting seat 603. Movable slots 605 are evenly opened through the top of the first mounting plate 3 and the second mounting plate 5. Movable plates 606 are connected inside the upper and lower movable slots 605. An L-shaped rod 607 is connected to the top of the movable plate 606. A connecting seat 608 is fixed to the bottom of one side of the movable plate 606. A turntable 609 is fixed to the bottom end of the screw 601. The clamping mechanism 6 also includes limiting slots 610 opened in the middle of both sides of the bottom movable slot 605.

[0025] It is worth noting that, see Figure 4 The limiting mechanism 7 includes a fastening bolt 701 that is threaded through and screwed to the top edge of the first mounting plate 3.

The pull rod 706 passes through the sliding block 704. Located on one side of the middle of the outer casing 704; when the turntable 609 rotates, it drives the mounting ring 702 to move, thereby causing the limiting tooth 703 to deflect and press against the inclined surface of the clamping block 705, thereby compressing the return spring 707. When the limiting tooth 703 separates from the clamping block 705, the return spring 707 resets the clamping block 705, thereby blocking the limiting tooth 703 and preventing the turntable 609 from rotating. Then, the fastening bolt 701 is rotated to press the fastening bolt 701 against the turntable 609, further securing the turntable 609 and preventing it from loosening, ensuring the stability of the clamped workpiece, preventing loosening, and improving the processing quality.
