Technical Field
[0001] This utility model relates to the field of gear processing and grinding technology, specifically a gear processing and grinding device. Background Technology
[0002] Gears are mechanical components with teeth on their rims that can continuously mesh to transmit motion and power. They consist of teeth, hubs, and other parts, and are classified in different ways according to tooth profile, shape, and function. During operation, they transmit motion and power by meshing with each other's teeth. They are used in various mechanical transmission devices such as automobile transmissions, industrial speed reducers, and watch transmission mechanisms. During production, the surface of the gears needs to be polished by a polishing device to remove burrs.
[0003] The existing announcement number CN219725640U discloses a grinding device for machining reducer gears, including a grinding box. A support frame is fixedly connected to the inner wall of the grinding box. A reducer gear body is placed on the surface of the support frame. A positioning component for limiting the position of the reducer gear body is provided on the top of the support frame. A grinding component is provided on the top of the grinding box. A debris collection component is provided on the inner wall of the grinding box. The positioning component includes a key pin, which is fixedly connected to the top of the support frame. The key pin is adapted to the keyway on the surface of the reducer gear body. The reducer gear body is movably sleeved on the surface of the key pin. In use, this device facilitates rapid grinding of reducer gears, effectively limits the position of the gear during grinding, and can screen and collect the debris generated during grinding, making subsequent debris recycling more convenient.
[0004] Since gears also have burrs on their surface, they need to be polished to ensure the precision and flatness of the finished product. However, the above-mentioned device can only polish the tooth surface of the gear, which means that after polishing, other polishing equipment is needed to polish the surface, which is very troublesome and affects the overall processing efficiency. Therefore, we propose a gear processing polishing device. Utility Model Content
[0005] The purpose of this utility model is to provide a gear processing and grinding device to solve the problem mentioned in the background art that the existing device can only grind the tooth surface of the gear, but cannot grind the surface. This results in the need to use other grinding equipment to grind the surface after the initial grinding, which is very troublesome and affects the overall processing efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a gear processing and grinding device, comprising a housing, a hollow mounting column fixedly connected to the middle of the bottom of the inner cavity wall of the housing, a servo motor fixedly connected to the top of the housing by bolts, the output shaft of the servo motor extending into the inner cavity of the housing and fixedly connected to an L-shaped frame, a vertical groove opened on the inner side wall of the L-shaped frame, a first mounting rod fixedly connected between the top and bottom of the inner cavity wall of the vertical groove, an L-shaped plate slidably connected to the outer side wall of the first mounting rod, a pressing spring sleeved on the outer side wall of the first mounting rod, a horizontal plate fixedly connected to the lower side of the inner side wall of the L-shaped frame, and grinding blocks fixedly connected to the top of the horizontal plate and the end of the L-shaped plate.

A T-shaped mounting groove is opened on the top of the horizontal plate and on the right side of the grinding block below. A steel wire grinding brush is slidably connected to the inner wall of the T-shaped mounting groove. The top of the steel wire grinding brush extends to the outside of the T-shaped mounting groove.
[0009] As a further description of the above technical solution:
[0010] A first screw is screwed onto the upper side of the front wall of the L-shaped frame, and a second screw is screwed onto the front wall of the horizontal plate, and the second screw is screwed onto the steel wire grinding brush.
[0011] As a further description of the above technical solution:
[0012] The front side wall of the box is connected to a door via a hinge, and the inside of the door is made of tempered glass.
[0013] As a further description of the above technical solution:
[0014] The hollow mounting column has slots on the left and right sides of its outer wall. A fixing block is slidably connected to the inner wall of the slot. A second mounting rod is fixedly connected to the upper side between the left and right sides of the inner wall of the hollow mounting column.

[0018] The outer walls of the two fixing blocks are provided with gaskets, and the gaskets are made of polyurethane rubber.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] This gear processing and grinding device uses a servo motor to drive an L-shaped frame to rotate. The rotation of the L-shaped frame drives the horizontal plate and the L-shaped plate to rotate, which in turn drives the upper and lower grinding blocks to grind the burrs on the gear surface. During grinding, the L-shaped plate, through the first mounting rod and the pressing spring, ensures that the grinding blocks can fit tightly against the gear surface, improving the grinding effect. At the same time, the horizontal plate drives the wire grinding brush to grind the burrs in the gear tooth surface. The wire grinding brush, together with the two grinding blocks, performs all-round grinding on the gear, improving the grinding effect. It can easily and quickly grind gears from all angles, thus improving the overall processing efficiency.
[0021] This gear processing and grinding device uses an electric telescopic rod to move an isosceles trapezoidal block. The isosceles trapezoidal block then presses and limits the fixed blocks on both sides. The fixed blocks on both sides cooperate with the isosceles trapezoidal block through a second mounting rod and a mounting slider to quickly fix the gear during grinding. At the same time, it is convenient to remove the gear after grinding. This device allows for convenient and quick disassembly and assembly of the gear during grinding, thereby further improving processing efficiency. Attached Figure Description

Figure 1-6 Including the housing 100;
[0033] Please refer to it again. Figure 1-4A hollow mounting column 200 is fixedly connected to the bottom center of the inner cavity wall of the housing 100. A servo motor 110 is fixedly connected to the top of the housing 100 by bolts. The servo motor 110 is used to drive the L-shaped frame 111 to rotate. The output shaft of the servo motor 110 extends into the inner cavity of the housing 100 and is fixedly connected to the L-shaped frame 111. The L-shaped frame 111 is used to drive the L-shaped plate 114 and the horizontal plate 116 to rotate. A vertical groove 112 is opened on the inner side wall of the L-shaped frame 111. The vertical groove 112 is used to install the first mounting rod 113. The first mounting rod 113 is fixedly connected between the top and bottom of the inner cavity wall of the vertical groove 112. The first mounting rod 113 is used to install the L-shaped plate 114. The L-shaped plate 114 is slidably connected to the outer side wall of the first mounting rod 113. Plate 114 is used to mount the upper grinding block 117 to grind the upper surface of the gear. A pressing spring 115 is sleeved on the outer wall of the first mounting rod 113. The pressing spring 115 is used to ensure that the grinding block 117 can fit tightly against the gear surface. A horizontal plate 116 is fixedly connected to the lower side of the inner wall of the L-shaped frame 111. The horizontal plate 116 is used to mount the lower grinding block 117 to grind the lower surface of the gear. At the same time, it works with the wire grinding brush 121 to grind the tooth surface of the gear. Grinding blocks 117 are fixedly connected to the top of the horizontal plate 116 and the end of the L-shaped plate 114. The grinding blocks 117 are used to grind the gear surface. The L-shaped plate 114 is slidably connected to the inner wall of the vertical groove 112. The pressing spring 115 is located above the L-shaped plate 114. A T-shaped mounting groove 120 is provided on the top and right side of the lower grinding block 117. The T-shaped mounting groove 120 is used to install a wire grinding brush 121. The inner wall of the T-shaped mounting groove 120 is slidably connected to the wire grinding brush 121. The wire grinding brush 121 is used to grind the tooth surface of the gear. The top of the wire grinding brush 121 extends to the outside of the T-shaped mounting groove 120. A first screw 130 is screwed to the upper side of the front side wall of the L-shaped frame 111. The first screw 130 is used to temporarily limit the L-shaped plate 114 when installing and removing the gear. A second screw 131 is screwed to the front side wall of the horizontal plate 116. The second screw 131 is used to fix the wire grinding brush 121, and the second screw 131 is screwed to the wire grinding brush 121. The front side wall of the housing 100 is open. A hinged door 140 is connected to the gear assembly. The door 140, along with its tempered glass interior, allows for easy inspection of the gear grinding process while preventing grinding debris from escaping. The tempered glass interior of the door 140 is used when the servo motor 110 is powered on. The output shaft of the servo motor 110 rotates, driving the L-shaped frame 111 to rotate. This rotation of the L-shaped frame 111 simultaneously drives the L-shaped plate 114 and the horizontal plate 116 to rotate, which in turn rotates the grinding blocks 117 on both sides, grinding the upper and lower surfaces of the gear. During grinding, a pressing spring 115, in conjunction with the first mounting rod 113, ensures that the grinding blocks 117 are tightly fitted against the gear surface. Simultaneously, the rotation of the horizontal plate 116 drives the wire grinding brush 121 to rotate.The steel wire grinding brush 121 rotates to grind the tooth surface of the gear, and the two work together to grind the gear from all angles.
[0034] In summary, this method allows for convenient and quick all-around grinding of gears, thereby improving overall processing efficiency.
[0035] Please refer to it again. Figure 1 , Figure 2 , Figure 5 and Figure 6The hollow mounting post 200 has slots 210 on both the left and right sides of its outer wall. These slots 210 facilitate the entry and exit of the fixing block 211. The fixing block 211 is slidably connected to the inner wall of the slot 210, and is used to fix the gear for subsequent grinding. A second mounting rod 212 is fixedly connected to the upper side between the left and right sides of the inner wall of the hollow mounting post 200. The second mounting rod 212 cooperates with the mounting slider 213 to limit the movement of the fixing block 211. The mounting slider 213 is slidably connected to both sides of the outer wall of the second mounting rod 212, and is used to mount the fixing block 211. The bottom of the mounting slider 213 is fixedly connected to the top of the fixing block 211. The inner walls of both fixing blocks 211 are sloped to facilitate the movement of the isosceles trapezoidal block 221. An electric telescopic rod 220 is fixedly connected to the bottom of the inner wall of the hollow mounting column 200. The electric telescopic rod 220 facilitates the movement of the isosceles trapezoidal block 221. The top of the electric telescopic rod 220 is fixedly connected to the isosceles trapezoidal block 221, which limits and fixes the fixing block 211. The isosceles trapezoidal block 221 is located between the two fixing blocks 211. Gaskets 230 are provided on the outer walls of the two fixing blocks 211. The shim 230 is designed to increase friction between the shim and the gear, thereby improving the fixing effect. The shim 230 is made of polyurethane rubber, which has high hardness, high elasticity, high wear resistance, and good tear resistance. It can withstand significant pressure and tension, providing strong clamping force to ensure the object is firmly fixed. In use, the gear is fitted onto the hollow mounting post 200, and then the power to the electric telescopic rod 220 is turned on. The output end of the electric telescopic rod 220 drives the isosceles trapezoidal block 221 to move upwards. The upward movement of the isosceles trapezoidal block 221 is controlled by the fixing blocks 211 on both sides. The slope of the slope pushes the fixing blocks 211 on both sides outward, causing the fixing blocks 211 on both sides to drive the mounting slider 213 to slide on the second mounting rod 212, thereby moving the fixing blocks 211 to the outside of the slot 210 to contact the gear. As the isosceles trapezoidal block 221 continues to move, it continuously applies pressure to the fixing blocks 211 on both sides, so that the fixing blocks 211 on both sides, together with the shims 230, firmly fix the gear, which is convenient for subsequent grinding. When disassembly is required, simply control the electric telescopic rod 220 to drive the isosceles trapezoidal block 221 to move downward, thereby releasing the fixation of the gear, and then remove the gear from the hollow mounting column 200.
[0036] In summary, this technology allows for convenient and quick disassembly and assembly of gears during grinding, thereby further improving processing efficiency.
[0037] In practical use, those skilled in the art lift the L-shaped plate 114 upwards. Once it reaches the designated position, rotate the first screw 130 to allow it to enter the vertical groove 112, thus limiting the L-shaped plate 114. Simultaneously, rotate the second screw 131 to release the fixation of the wire grinding brush 121, moving the wire grinding brush 121 to one side through the T-shaped mounting groove 120. Next, mount the gear onto the hollow mounting post 200, ensuring the lower surface of the gear contacts the lower grinding block 117. Then, connect the power supply to the electric telescopic rod 220, and the output of the electric telescopic rod 220... The isosceles trapezoidal block 221 moves upward, and the slope of the fixed blocks 211 on both sides pushes the fixed blocks 211 outward, causing the fixed blocks 211 to drive the mounting slider 213 to slide on the second mounting rod 212. This moves the fixed blocks 211 to the outside of the slot 210 and into contact with the gear. As the isosceles trapezoidal block 221 continues to move, it continuously applies pressure to the fixed blocks 211 on both sides, causing the fixed blocks 211 to work with the shims 230 to firmly fix the gear. The steel wire polishing brush 121 is then moved to reset its position against the gear tooth surface. After contact is established and secured by the second screw 131, the first screw 130 is rotated to release the limiting position of the L-shaped plate 114. By slowly releasing the L-shaped plate 114 while holding it, the upper grinding block 117 contacts the upper gear surface. Then, the power supply to the servo motor 110 is turned on. The output shaft of the servo motor 110 rotates, driving the L-shaped frame 111 to rotate. The rotation of the L-shaped frame 111 simultaneously drives the L-shaped plate 114 and the horizontal plate 116 to rotate. The rotation of the L-shaped plate 114 and the horizontal plate 116 drives the grinding blocks 117 on both the upper and lower sides to rotate simultaneously, grinding the upper and lower surfaces of the gear. During grinding, the spring 115 is pressed in conjunction with the first screw 130. An installation rod 113 makes the grinding block 117 fit tightly against the tooth surface. At the same time, when the horizontal plate 116 rotates, it drives the wire grinding brush 121 to rotate. The rotation of the wire grinding brush 121 grinds the tooth surface of the gear. The two work together to grind the gear in all directions. After completion, repeat the operation of the L-shaped plate 114 and the wire grinding brush 121 to disengage the upper grinding block 117 and the wire grinding brush 121 from the gear. Then, control the electric telescopic rod 220 to move the isosceles trapezoidal block 221 downward, thereby releasing the gear from the fixation. Then, the ground gear can be removed from the hollow installation column 200.
