Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding device technology, and in particular to a grinding device for gear production and processing. Background Technology
[0002] In the field of mechanical transmission, gears are core components, and their machining quality directly affects the operating accuracy and service life of mechanical equipment. In the gear machining process, grinding is an indispensable key step, mainly involving removing burrs from the tooth groove end faces to improve surface finish, thereby reducing transmission noise and wear.
[0003] Existing gear grinding devices have some shortcomings in practical applications. On the one hand, traditional devices have a relatively simple method of fixing gears, often using general-purpose fixtures or manual positioning of individual gears. On the other hand, existing devices have poor versatility and cannot be adapted to gears of different specifications. When it is necessary to process gears of different sizes, it is often necessary to change the entire set of fixtures, which is cumbersome, has low processing efficiency, and high production costs. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a grinding device for gear manufacturing and processing, which has the advantages of being able to achieve rapid fixing by utilizing gear meshing relationships and being adjustable, thus solving some of the problems mentioned in the background technology.
[0005] This utility model provides the following technical solution: a grinding device for gear production and processing, including an automatic grinding machine. A processing table is fixedly installed on the upper part of the machine platform of the automatic grinding machine. A fixing component is rotatably installed at the middle of the upper end of the processing table. An internally threaded cylinder is slidably installed in the middle of the interior of the fixing component. An adjusting screw is threadedly connected to the front end of the internally threaded cylinder. A top block is rotatably connected to the front end of the adjusting screw. A clamping component is installed at the front end of the top block. A screw hole is provided in the middle of the interior of the clamping component. A matching hexagonal socket head cap screw passes through the screw hole. The rear end of the hexagonal socket head cap screw is threadedly connected to the interior of the top block. An arc-edged abutment is fixedly connected to the rear end of the internally threaded cylinder. A fastener passes through and is threadedly connected to the upper end of the fixing component. The lower end of the fastener abuts against the upper end of the internally threaded cylinder.
[0006] Furthermore, the processing table is provided with sliding grooves on both the left and right sides of the fixing component. Sliding blocks are slidably connected through the interior of each sliding groove, and top blocks are fixedly installed at the adjacent ends of each sliding block to ensure the rationality of the structural design.
[0007] Furthermore, each of the two top blocks is equipped with a second clamp at one of its adjacent ends. The second clamp is fixedly connected to the top block by an internal hex bolt. That is, the side gear is also limited by the structure of the first clamp to prevent shaking and is detachable and replaceable. At the same time, the meshing between the gears is achieved by the clamping action of the slider.
[0008] Furthermore, a bidirectional screw is rotatably installed at the lower middle of the processing table. Two sets of symmetrically designed limiting seats are threaded onto the bidirectional screw. The upper ends of the limiting seats are fixedly connected to the slider, and the upper ends of the limiting seats are in contact with the processing table to improve structural stability.
[0009] Furthermore, a handwheel is fixedly installed at the right end of the bidirectional screw, and the handwheel is designed to facilitate user operation.
[0010] The advantages of this utility model are as follows:
[0011] 1. By adjusting the screw, the drive clip is engaged in the keyway of the middle gear, and the arc-edge abutment is used to achieve tight positioning of the inner ring. At the same time, the double-sided screw drives the gears on both sides to move towards the middle. The gear meshing relationship completes the relative positioning and fixing of the three sets of gears, so that the gears remain stable during grinding, avoiding uneven grinding caused by positioning deviation, and can simultaneously expose the gear end face so that the grinding head can work quickly, improving grinding efficiency and the consistency of surface quality.
[0012] 2. The extension length of the clamp can be flexibly adjusted by turning the adjusting screw to match the keyway depth of different gear sizes. At the same time, clamp one and clamp two can be disassembled and replaced by internal hex bolts to adapt to different specifications of gear keyways and inner ring structures, improving the adaptability of the device to diverse gear products. This adjustable design not only improves the flexibility of the operator during use, but also makes it more practical. Attached Figure Description

Detailed Implementation
[0018] 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.
[0019] Please see Figures 1-3 A grinding device for gear manufacturing includes an automatic grinding machine 1. A processing table 2 is fixedly mounted on the upper part of the machine platform of the automatic grinding machine 1. A fixing component 3 is rotatably mounted at the middle of the upper end of the processing table 2. An internally threaded cylinder 4 is slidably mounted inside the middle of the fixing component 3. An adjusting screw 5 is threadedly connected to the front end of the internally threaded cylinder 4. A top block 6 is rotatably connected to the front end of the adjusting screw 5. A clamping component 7 is mounted at the front end of the top block 6. A screw hole 8 is provided in the middle of the interior of the clamping component 7. A matching internal hexagon bolt 9 passes through the screw hole 8. The rear end of the internal hexagon bolt 9 is threadedly connected to the interior of the top block 6. An arc-edged abutment 10 is fixedly connected to the rear end of the internally threaded cylinder 4. A fastener 11 is threadedly connected to the upper end of the fixing component 3. The lower end of the fastener 11 abuts against the internally threaded cylinder 4. At the upper end of the groove cylinder 4, the gear with machined teeth and grooves is placed in the middle of the upper end of the processing table 2. By using a wrench or other tools to turn and adjust the extension length of the adjusting screw 5, the locking piece 7 is inserted into the keyway of the gear. At the same time, the arc-edged abutment block 10 is pressed against the other side of the inner ring of the gear, thereby completing the limiting and fixing of the intermediate gear. By unscrewing the internal hex bolt 9 from the inside of the locking piece 7 and the locking piece 15, different sizes of locking pieces 7 and 15 can be replaced to match different sizes of gears and gear keyways. Then, through the above-mentioned tightening and adjustment operations, the fixing of gears of different sizes can be completed, which improves the applicability of this device. This adjustable design not only improves the flexibility of the operator during use, but also makes it more practical.
[0020] Please see Figures 2-4On the machining table 2, there are sliding grooves 12 on both the left and right sides of the fixing part 3. Sliding blocks 13 are slidably connected through the interior of each sliding groove 12. Top blocks 14 are fixedly installed at the adjacent ends of the sliding blocks 13, and clamping parts 15 are installed at the adjacent ends of the top blocks 14. The clamping parts 15 are fixedly connected to the top blocks 14 by hexagonal socket bolts 9. A bidirectional screw 16 is rotatably installed at the lower center of the machining table 2. Two sets of symmetrically designed limiting seats 17 are threaded onto the bidirectional screw 16. The upper ends of the limiting seats 17 are fixedly connected to the sliding blocks 13, and the upper ends of the limiting seats 17 are in contact with the machining table 2. A handwheel 18 is fixedly installed on the right end of the bidirectional screw 16. After aligning the keyways of the other two sets of gears with the clamping parts 15 and placing them on the machining table 2, the bidirectional screw 16 is rotated by turning the handwheel 18. The bidirectional screw 16 rotates, driving the two sets of limiting seats 17 to move relative to each other. This ultimately moves the gears on both sides towards the middle gear. By rotating and adjusting the middle gear, it meshes with the gears on both sides. The limiting relationship between the structures then fixes the three sets of gears. By turning on the automatic grinding machine 1, the grinding head can run and grind the tooth groove end faces of the gears to remove burrs. This device utilizes the meshing relationship between gears to quickly fix the three sets of gears, while also exposing their end faces to the top. This allows the grinding head to quickly polish and grind, improving surface smoothness and ensuring product consistency. It is worth mentioning that when a large number of gears need to be ground, the middle gear can be retained, and only the gears on both sides need to be replaced, thereby improving processing efficiency.
[0021] Working principle: Place the gear with machined teeth and grooves at the upper center of the machining table 2. Use a wrench or other tools to adjust the extension length of the adjusting screw 5, causing the locking piece 7 to engage in the keyway of the gear. Simultaneously, the arc-edged abutment 10 abuts against the other side of the inner ring of the gear and tightens, thus completing the limiting and fixing of the middle gear. Then, align the keyways of the other two sets of gears with the locking piece 15 and place them on the machining table 2. Rotate the handwheel 18 to drive the bidirectional screw 16 to rotate. The rotation of the bidirectional screw 16 drives the two sets of limiting seats 17 to move relative to each other, ultimately driving the gears on both sides towards the center. The intermediate gear moves, and by rotating and adjusting the intermediate gear, it meshes with the gears on both sides. Then, the three sets of gears are fixed through the limiting relationship between the structures. By turning on the automatic grinder 1, the grinder head can be run and the end face of the gear tooth groove can be ground. Furthermore, by unscrewing the internal hex bolt 9 from the inside of the first clip 7 and the second clip 15, clips of different sizes can be replaced with clips of different sizes 7 and 15, so as to match with gears of different sizes and gear keyways. Then, by the above-mentioned tightening and adjustment operations, the gears of different sizes can be fixed.
