Abstract
Description
Technical Field
[0001] This utility model belongs to the field of gear processing technology, specifically relating to a grinding device for deburring precision gears. Background Technology
[0002] In the field of modern mechanical manufacturing, precision gears, as core transmission components of mechanical equipment, directly affect the operational accuracy and reliability of the entire mechanical system due to their machining quality. The grinding process, as a crucial step in improving the surface finish of precision gears and eliminating burrs and other machining marks, plays a decisive role in the performance and service life of the gears.
[0003] However, traditional precision gear deburring equipment generally relies on manual loading and unloading. Specifically, before grinding begins, operators must manually place the gear to be ground onto the designated station of the grinding equipment. After grinding, the gear must be removed from the equipment, and the next gear to be ground must be placed, repeating this cycle. This manual operation method has many drawbacks: firstly, frequent manual loading and unloading consumes a significant amount of time and labor, severely restricting production efficiency and failing to meet the demands of large-scale, high-efficiency modern production. Secondly, the stability and consistency of manual operation are difficult to guarantee, and operational errors can easily lead to inaccurate gear positioning, thus affecting grinding quality and increasing production costs. Furthermore, manual gear placement requires close proximity, posing a risk of direct contact with dangerous parts of the equipment. Therefore, there is an urgent need to develop a precision gear grinding equipment that can achieve continuous grinding and reduce manual intervention. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to an electrical connection; they can refer to a hydraulic connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0029] See Figure 1-2 As shown, the present invention provides a precision gear deburring and polishing device, including a cabinet 100, an operation panel 101 horizontally mounted on the cabinet 100, a feeding assembly at one end of the operation panel 101, and a gear to be polished placed in the feeding assembly. A clamping and polishing assembly is provided on one side of the feeding assembly, and a positioning and rotating assembly is provided in front of the clamping and polishing assembly. The clamping and polishing assembly can clamp the gear on the feeding assembly and place it in the positioning and rotating assembly for rotational polishing.
[0030] See Figure 3-4As shown, the aforementioned feeding assembly includes a base 102 fixedly mounted on an operation plate 101. A feeding seat 103 is mounted on the base 102, and a rectangular through hole 105 is horizontally formed at the bottom of the feeding seat 103. A rectangular push plate 104 passes through the rectangular through hole 105 of the feeding seat 103. The outer dimensions of the push plate 104 match the rectangular through hole 105 on the feeding seat 103. The push plate 104 is in contact with the upper surface of the base 102 and can move along the rectangular through hole 105. An electric actuator 107 is fixedly mounted on one side of the base 102, and the output end of the electric actuator 107 is fixedly connected to the push plate 104. A circular through hole 106 is vertically formed on the feeding base 103, communicating with a rectangular through hole 105. The central axis of the circular through hole 106 is perpendicular to the length direction of the rectangular through hole 105. Several positioning rods 108 are vertically fixedly installed on the feeding base 103, and the positioning rods 108 are arranged in an array along the circumference of the circular through hole 106. Several gears to be processed are placed in the circular through hole 106 in a stacked manner and are limited by the positioning rods 108. The lowest gear is located at the connection between the circular through hole 106 and the rectangular through hole 105. The height of the rectangular through hole 105 is the same as the thickness of the gear. A push plate 104 can contact the tooth surface of the gear. The top part of the push plate 104 that contacts the gear is designed as an arc surface, which matches the shape of the gear. A first conveyor belt 109 is provided on one side of the feeding base 103, and the rectangular through hole 105 of the feeding base 103 is flush with the surface of the first conveyor belt 109.
[0031] Initially, the electric actuator 107 is retracted. When a gear needs to be conveyed, the electric actuator 107 drives the push plate 104 to move along the rectangular through hole 105, with its top end contacting the lowest gear and pushing it out through the rectangular through hole 105. The pushed gear slides into the first conveyor belt 109 and is conveyed to its end via the first conveyor belt 109. After the gear is pushed out, the electric actuator 107 drives the push plate 104 to retract to its initial position. At this time, the gear above the circular through hole 106 automatically falls into the rectangular through hole 105 due to gravity, waiting for the next push. This process is repeated, realizing continuous and automatic gear feeding. The gear at the end of the first conveyor belt 109 is clamped and polished by the clamping and polishing assembly.
[0032] See Figure 5As shown, the clamping and grinding assembly includes two linearly distributed supports 201. The supports 201 are vertically fixed on the operating plate 101. A mounting plate 202 is horizontally fixed to the top of each support 201. A lead screw 203 and a guide rail 204 are horizontally mounted along the length of the mounting plate 202. A first moving block 205 and a second moving block 206, matching each other, are mounted on the lead screw 203. A first motor 207 is connected to one end of the lead screw 203. A first guide block 208 and a second guide block 209 are slidably mounted on the guide rail 204. The first guide block 208 is fixedly connected to the first moving block 205, and the second guide block 209 is fixedly connected to the second moving block 206. A first translation plate 210 is fixedly mounted on the first guide block 208, and a second translation plate 211 is fixedly mounted on the second guide block 209. When the first motor 207 drives the lead screw 203 to rotate, the first translation plate 210 and the second translation plate 211 can move horizontally along the guide rail 204.
[0033] A first slide rail 212 is vertically mounted on a first translation plate 210. A first slider 213 is slidably mounted on the first slide rail 212. A first lifting plate 214 is mounted on the first slider 213. A first electric cylinder 215 is fixedly mounted on the upper end of the first translation plate 210, and the output end of the first electric cylinder 215 is fixedly connected to the top end of the first lifting plate 214. A dual-axis cylinder 216 is fixedly mounted on the lower end of the first lifting plate 214. Both output shafts of the dual-axis cylinder 216 are connected to gripper seats 217. A gripper 218 is horizontally fixedly mounted on each gripper seat 217. The contact surface between the gripper 218 and the gear is an arc-shaped surface, and its arc-shaped surface is similar to the shape of the gear.
[0034] A second slide rail 219 is vertically mounted on the second translation plate 211. A second slider 220 is slidably mounted on the second slide rail 219. A second lifting plate 221 is mounted on the second slider 220. A second electric cylinder 222 is fixedly mounted on the upper end of the second translation plate 211, and the output end of the second electric cylinder 222 is fixedly connected to the top end of the second lifting plate 221. A concave grinding disc 223 is fixedly mounted on the lower end of the second lifting plate 221. When grinding the gear, the grinding disc 223 is moved so that the gear is located within the concave opening.
[0035] The first motor 207 drives the gripper 218 on the translation plate to move to the end of the first conveyor belt 109, and the first electric cylinder 215 drives the gripper 218 to move downward, so that the gripper 218 contacts the gear. The dual-shaft cylinder 216 drives the gripper 218 to clamp the gear. After clamping, it is fixed on the positioning and rotating assembly, and the grinding disc 223 moves to the gear, so that the gear is locked in the concave opening of the grinding disc 223 for grinding. During grinding, the positioning and rotating assembly can drive the gear to rotate.
[0036] See Figure 6As shown, the positioning rotation assembly includes a support base 301, which is vertically fixedly mounted on the operation plate 101. A plate 302 is fixedly mounted on the top of the support plate, and two bearing seats 303 are vertically mounted along the length of the plate 302, with a certain distance between the two bearing seats 303. A rotating shaft 304 is vertically rotatably mounted on one of the bearing seats 303, and a drive shaft 305 is rotatably mounted on the other bearing seat 303. The drive shaft 305 is located above the rotating shaft 304, and the drive shaft 305 and the rotating shaft 304 are installed opposite each other, with their central axes coinciding. Cylindrical clamps 306 are mounted on the bottom end of the drive shaft 305 and the top end of the rotating shaft 304. The chuck 306 can be locked in the central shaft hole of the gear. A first cylinder 307 is installed on the upper end of the plate 302. The output end of the first cylinder 307 is connected to the drive shaft 305. The first cylinder 307 can drive the drive shaft 305 to approach the rotating shaft 304 and clamp the gear between the drive shaft 305 and the rotating shaft 304.
[0037] A placement plate 308 is vertically fixed on the flat plate 302. A second motor 309 is mounted on the placement plate 308. A main sprocket is mounted on the output shaft of the second motor 309, and a driven sprocket is mounted on the drive shaft 305. A chain 310 connects the main sprocket and the driven sprocket. When the gear is clamped by the drive shaft 305 and the rotating shaft 304, the second motor 309 drives the drive shaft 305 to rotate, which in turn drives the gear to rotate. Before the gear rotates, the grinding disc 223 is moved so that the gear is engaged in the concave opening of the grinding disc 223. Subsequently, the gear contacts the inner wall of the concave opening of the grinding disc 223, and grinding is performed by the rotation of the gear.
[0038] See Figure 2 As shown, a second conveyor belt 401 is provided on one side of the positioning and rotating assembly. The polished gear is clamped by the gripper 218 and placed on the second conveyor belt 401. The gear can be transferred to the next process (such as packaging equipment) via the second conveyor belt 401. In addition, a chip collection box 402 is installed below the polishing disc 223. The chip collection box 402 is fixedly installed in the middle of the cabinet 100 and is located between the first conveyor belt 109 and the second conveyor belt 401. The chip collection box 402 has an upper opening, and an air duct 403 is connected to one side of the chip collection box 402. The air duct 403 is connected to a dust suction device 404. The chips generated during the polishing process can fall into the chip collection box 402 and be absorbed by the dust suction device 404.
[0039] See Figure 7 As shown, it should be noted that the first conveyor belt 109, the second conveyor belt 401, the gripper 218, the grinding disc 223, as well as the drive shaft 305 and the rotating shaft 304 are all in the same vertical plane.
[0040] Example: Several gears to be ground are placed in the feeding seat 103 and limited by several positioning rods 108. When grinding is required, the electric push rod 107 drives the push plate 104 to push the gear out of the feeding seat 103 and slide it into the first conveyor belt 109, where it is conveyed to its end. Subsequently, the first motor 207 drives the first translation plate 210 and the gripper 218 to move to the end of the first conveyor belt 109, and the first electric cylinder 215 drives the gripper 218 to move downward, so that the gripper 218 contacts the gear, and the dual-shaft cylinder 216 drives the gripper 218 to clamp the gear. Then, the clamped gear is moved between the drive shaft 305 and the rotating shaft 304, and the first cylinder 307 drives the drive shaft 305 to move closer to the rotating shaft 304, whereby the drive shaft 305 and the rotating shaft 304 clamp the gear. Then, the first motor 207 drives the second translation plate 211 and the grinding disc 223 to move, so that the gear is locked in the concave opening of the grinding disc 223, and the second motor 309 drives the gear to rotate for grinding. After grinding, the gear is clamped again by the gripper 218 and placed on the second conveyor belt 401 to complete the entire grinding process.
