Description

Technical Field

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

[0002] Gears are common mechanical transmission components widely used in various mechanical devices. A gear is a mechanical part composed of teeth, hub, spokes, and rim, typically mounted on a shaft. It transmits motion and power through meshing teeth, primarily used for transmitting power, changing speed, and direction of motion. After heat treatment, the tooth surface of gears may deform, requiring precision machining to improve tooth profile accuracy and surface quality. To improve corrosion resistance, wear resistance, and appearance, surface treatments such as galvanizing, hard chrome plating, and blackening can be applied. The main purpose of gear blank machining is to provide a precise positioning reference for subsequent tooth profile machining and to machine the gear's outer diameter, inner bore, end face, and other reference surfaces. This typically includes turning and grinding processes, utilizing the relative motion between a hob and the gear blank to cut the tooth profile. The hob is essentially a helical gear with a large helix angle. On a hobbing machine, the rotational motion of the hob maintains a certain transmission ratio with the rotational motion of the gear blank, thereby machining an involute tooth profile. Gear hobbing is a high-efficiency machining process suitable for machining spur gears, helical gears, and other similar gears. It involves using a gear hobbing cutter to perform reciprocating motions and circular feed motions on the gear blank to cut the tooth profile. The gear hobbing cutter is shaped like a gear, with its cutting edges distributed along the tooth profile.

[0003] In the existing technology, during the grinding and polishing process of gears, the gears need to be placed on a processing table and then processed by the processing equipment on the processing table. During the processing of gears, the gears need to be reliably clamped and fixed to ensure processing accuracy and quality, and to prevent the gears from shaking during the processing process, which would lead to a deterioration in the gear processing effect.

[0004] However, existing gear processing clamping devices have certain shortcomings in clamping stability, which leads to increased processing errors, affecting the final quality of the gears. Furthermore, when clamping gears of different sizes and specifications, it is inconvenient to adjust the clamping device, affecting the processing efficiency of gears of different sizes and specifications. Utility Model Content

[0005] The purpose of this invention is to provide a stable gear processing clamping device, which solves the problem in the prior art where it is inconvenient to adjust the gears when processing gears of different sizes, resulting in instability during gear processing and affecting the gear processing effect and efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gear processing clamping device with stable clamping includes a processing table. The top of the processing table has two arc-shaped sliding grooves. Inside the sliding grooves, two mounting plates are provided through a mounting mechanism. The top of the mounting plates has a T-shaped adjustment groove. Inside the adjustment groove, a T-shaped adjustment block is provided through an adjustment mechanism. A clamping rod is fixedly connected to the top of the adjustment block. One end of the clamping rod is fixedly connected to a trapezoidal pressing block. The top of the pressing block has an abutment groove. A screw is threadedly connected inside the abutment groove.

[0008] Preferably, the installation mechanism includes a mounting block fixedly connected to the side of the mounting plate, a plurality of mounting slots are provided at the bottom of the slide, a T-shaped mounting rod is provided at the top of the mounting block, and the bottom of the mounting rod is provided inside the adjacent mounting slot.

[0009] Preferably, the top of the mounting rod is elastically connected to the top of the mounting block via a compression spring.

[0010] Preferably, the adjustment mechanism includes several anti-movement grooves formed on the top of the mounting plate, and L-shaped anti-movement rods are rotatably connected to both sides of the adjustment block, with one end of the anti-movement rod located inside the adjacent anti-movement groove.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-5A gear processing clamping device with stable clamping includes a processing table 1. When a gear needs to be processed, it is placed on the processing table 1, clamped and fixed, and then processed. The top of the processing table 1 has two arc-shaped sliding grooves 2. Inside the sliding grooves 2, two mounting plates 4 are provided via a mounting mechanism 3. When clamping and fixing the gear, the mounting plates 4 can be rotated inside the sliding grooves 2 to adjust the position of a clamping rod 8. After the clamping rod 8 is adjusted, the mounting plate 4 is easily fixed via the mounting mechanism 3, thus fixing the position of the clamping rod 8 on the mounting plate 4. This facilitates the clamping block 9 on the clamping rod 8 to fix the gear, making gear processing more convenient. The top of the mounting plate 4 has a T-shaped adjustment groove 5. Inside the adjustment groove 5, a T-shaped adjustment block 7 is provided via an adjustment mechanism 6. After the position of the clamping rod 8 is adjusted, the adjustment mechanism 6 allows the adjustment block 7 to slide inside the adjustment groove 5, ensuring that the clamping block 9 on the clamping rod 8 can clamp the gear. The gear is pressed and fixed to ensure its stability. A clamping rod 8 is fixedly connected to the top of the adjusting block 7. The clamping rod 8 can easily move the pressing block 9 closer to the gear by moving the adjusting block 7. The pressing block 9 fixes the gear and ensures the stability of the gear during processing. A trapezoidal pressing block 9 is fixedly connected to one end of the clamping rod 8. The trapezoidal pressing block 9 fixes the gear by entering between the teeth of the gear and ensuring the stability of the gear during processing. The top of the pressing block 9 has an abutting groove 10. A screw 11 is threadedly connected inside the abutting groove 10. When the pressing block 9 enters between the two teeth of the gear, the screw 11 inside the abutting groove 10 is rotated so that one end of the screw 11 abuts against the teeth. This ensures that the pressing block 9 and the screw 11 fix the gear, making it easy to fix the gear during processing. When processing gears of different sizes and specifications, it is convenient to fix gears of different sizes and specifications, so that the gears can be fixed quickly and easily during processing, ensuring the efficiency of gear processing.

[0024] Furthermore, the mounting mechanism 3 includes a mounting block 301 fixedly connected to the side of the mounting plate 4. The bottom of the slide 2 is provided with several mounting slots 302. A T-shaped mounting rod 303 is passed through the top of the mounting block 301. The bottom of the mounting rod 303 passes through the interior of the adjacent mounting slots 302. When the mounting plate 4 moves inside the slide 2, the mounting rod 303 on the mounting block 301 can be pulled upward first, and then the mounting plate 4 can be moved. After the mounting plate 4 is in place, the mounting rod 303 is released so that the mounting rod 303 can descend into the interior of the mounting slot 302 by its own gravity, thereby fixing the position of the mounting plate 4. This facilitates the adjustment of the clamping rod 8 and the clamping and fixing of the gear. Before adjusting the position of the mounting plate 4, the mounting rod 303 needs to be pulled upward so that the mounting plate 4 can move freely without restriction. This facilitates both easy changing and easy fixing of the position of the mounting plate 4.

[0025] Furthermore, the top of the mounting rod 303 is elastically connected to the top of the mounting block 301 via a compression spring 304. When the mounting rod 303 needs to enter the mounting groove 302 to fix the position of the mounting plate 4, the elastic force of the compression spring 304 can give the mounting rod 303 a downward force, thereby ensuring that the mounting rod 303 will not easily disengage from the mounting groove 302 and cause the mounting plate 4 to shake, thus ensuring the stability of the mounting rod 303 in fixing the mounting plate 4.

[0026] Furthermore, the adjustment mechanism 6 includes several anti-movement grooves 601 formed on the top of the mounting plate 4. Both sides of the adjustment block 7 are rotatably connected to L-shaped anti-movement rods 602. One end of the anti-movement rod 602 is located inside the adjacent anti-movement groove 601. When the adjustment block 7 is moved to drive the clamping rod 8 to move and clamp and fix the gear, the anti-movement rod 602 can be rotated first so that the anti-movement rod 602 can be disengaged from the anti-movement groove 601. Then the position of the adjustment block 7 is changed. After the position is changed, the anti-movement rod 602 is rotated back into the anti-movement groove 601 so that the position of the adjustment block 7 is fixed, which makes it easy to determine the position of the clamping rod 8, so that the pressing block 9 on the clamping rod 8 can easily enter between the teeth to fix the gear.

[0027] Furthermore, a lever 603 is fixedly connected to the surface of the anti-movement rod 602, and two anti-rotation plates 604 are rotatably connected to the top of the mounting plate 4. When the anti-movement rod 602 enters the anti-movement groove 601, the lever 603 can be used to easily rotate the anti-movement rod 602. Then, the anti-rotation plates 604 are rotated to block the top of the anti-movement groove 601, so that the anti-movement rod 602 will not easily rotate out of the anti-movement groove 601, thus ensuring the stability of the anti-movement rod 602.

[0028] Furthermore, one end of the screw 11 is rotatably connected to a stop block 12. When the screw 11 needs to be rotated so that one end of the screw 11 abuts against the teeth on the gear, the friction can be increased by the stop block 12, so that the screw 11 and the pressing block 9 can better fix the gear and ensure the stability of the gear.

[0029] In summary:

[0030] When machining gears, the gears can first be placed on the machining table 1. Then, according to different gear sizes and specifications, the mounting plate 4 can be moved inside the slide groove 2, allowing the clamping rod 8 on the mounting plate 4 to move to the appropriate position. Next, the mounting rod 303 on the mounting block 301 is lowered. The mounting rod 303 moves downwards into the mounting groove 302 under the force of the compression spring 304, thus fixing the position of the mounting plate 4. Then, the adjusting block 7 is moved inside the adjusting groove 5, causing the clamping rod 8 to adjust its position, facilitating the insertion of the pressing block 9 between the teeth of the gear to clamp and fix it. After the adjusting block 7 is adjusted, the anti-rotation rod 602 can be easily rotated into the anti-rotation groove 601 by the actuating rod 603. Then, the anti-rotation plate 604 is rotated to prevent the anti-rotation rod from rotating. The top of the moving groove 601 is blocked to ensure that the anti-moving rod 602 will not easily disengage from the anti-moving groove 601. Then, the screw 11 that is abutting inside the groove 10 is rotated, so that the abutting block 12 at one end of the screw 11 is driven to engage with the clamping teeth on the gear. The abutting block 12 and the pressing block 9 cooperate to clamp and fix the gear, so that the gear will not shake during the gear processing and become unstable. It can also easily process gears of different sizes and specifications, ensuring that gears of different sizes and specifications can be easily clamped and fixed for processing. With the above structure, when it is necessary to process gears of different sizes and specifications, the pressing block 9 can be easily adjusted to enter the interior of the clamping teeth, and then the screw 11 is rotated, so that the abutting block 12 on the screw 11 cooperates with the pressing block 9 to clamp and fix the gear, ensuring the stability of gears of different sizes and specifications during processing.
