Description

Technical Field

[0001] The utility model relates to the technical field of polishing machines, in particular to a polishing machine for manufacturing metal tools that can prevent deviation. Background Technique

[0002] A polishing machine is a device used to polish the surface of an object. During operation, the motor drives the polishing disc to rotate at a high speed. Through the friction between the polishing materials (such as polishing paste, sandpaper, polishing cloth, etc.) on the polishing disc and the surface of the object to be polished, surface defects, scratches, oxide layers, etc. are removed, so that the surface of the object becomes smooth, bright, and flat. Polishing machines are widely used in industries such as metal processing, car beauty, jewelry processing, and wood processing. When manufacturing metal tools, for some tools with long handles or brackets, the pipes or grips they hold are mostly tubular and also need to be polished.

[0003] Most of the existing polishing machines fix the pipe and then perform the polishing process through the polishing machine. However, only one end of the pipe is fixed. The vibration generated by the high-speed rotation of the polishing wheel is very likely to cause the pipe to deviate at the clamped part, resulting in inaccurate polishing work. Moreover, it is very inconvenient to disassemble and reinstall the fixture every time the pipe is adjusted or polished pipes with different diameters. Content of the Utility Model

[0004] The purpose of the utility model is to provide a polishing machine for manufacturing metal tools that can prevent deviation, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A polishing machine for manufacturing metal tools that can prevent deviation, including a machine base and a bracket. The inside of the bracket is penetrated and rotatably connected with a connecting frame. The top of the connecting frame is provided with a polishing machine body. When polishing the pipe in the metal tool, insert the pipe into two groups of positioning rings and make the pipe fall on the positioning block directly below. Then start the polishing machine body to make the polishing wheel rotate. Subsequently, slowly push the polishing machine body to make the position where the polishing machine body is rotatably connected with the bracket through the connecting frame rotate. A polishing wheel is arranged inside the polishing machine body, and a positioning part for preventing the metal pipe from deviating during grinding is arranged inside the machine base. The positioning part includes:

[0006] The cam is provided with a plurality of teeth, and the cam is provided with a plurality of teeth, and the teeth are connected to each other with a plurality of teeth, and a plurality of teeth are connected to each other with a plurality of teeth.

[0007] Preferably, the inner wall of the positioning ring is fixedly connected to a fixing plate, and a sliding groove is provided on the surface of the fixing plate. When the turntable rotates, the transmission groove provided on the surface of the turntable will interfere with the sliding rod located in the transmission groove. However, since the sliding rod is fixedly connected to the push rod, and the push rod passes through the sliding groove and is slidably connected, the sliding groove limits the push rod. Further, when the sliding rod is moved by the transmission groove, the push rod can only slide in the sliding groove. The inner side of the sliding groove is penetrated and slidably connected with the push rod.

[0008] Preferably, a sliding rod is fixedly connected to the surface of the push rod, and the sliding rod passes through the transmission groove. When the sliding rod is moved by the transmission groove, the push rod can only slide in the sliding groove, and the push rod will push the positioning block to move toward the axis of the positioning ring.

[0009] Preferably, a slide plate is fixedly connected to the surface of the push rod, a return spring is fixedly connected to the surface of the slide plate, and one end of the return spring away from the slide plate is fixedly connected to the inner wall of the slide groove.

[0010] Preferably, one end of the push rod close to the center of the positioning ring is fixedly connected with a positioning block. When the positioning ring moves, it will resist the arc rod and force the arc rod to shrink toward the inside of the positioning block. At the same time, the arc rod will compress the arc spring 2 through the circular plate. At the same time, the positioning block can also pass through the arc rod passing through it, so that the three groups of positioning blocks and the arc rod can shrink inward in equal proportion in the shape of a circular ring. The positioning blocks that shrink equally in proportion through the two groups of positioning rings can make the axis centers of both ends of the pipe consistent. The number of the positioning blocks is three groups, and the three groups of positioning blocks are arranged in a circular array with the center line of the positioning ring as the axis center.

[0011] Preferably, an arc rod passes through the positioning block and the other two groups of positioning blocks, and the three groups of positioning blocks and the arc rods passing through them are together in a circular ring shape, so that when the positioning blocks are contracted, pipes of different diameters can be fixed, and the positioning blocks can fix the pipes as the polishing machine body is pressed down.

[0012] Preferably, both ends of the arc rod are fixedly connected with a circular plate, and the surface of the circular plate is fixedly connected with an arc spring 2. When the slide rod is moved by the transmission groove, the push rod can only slide in the slide groove, and the push rod will push the positioning block to move toward the axis of the positioning ring. When the positioning ring moves, it will resist the arc rod and force the arc rod to shrink toward the inside of the positioning block. At the same time, the arc rod will compress the arc spring 2 through the circular plate.

[0013] Compared with the prior art, the utility model provides a polishing machine for metal tool manufacturing that can prevent deviation, which has the following beneficial effects:

[0014] 1. The anti-deviating polishing machine for metal tool manufacturing has a sliding rod and a push rod that is fixedly connected to the sliding groove and slidably connected to the push rod, so that the sliding groove limits the push rod. When the sliding rod is moved by the transmission groove, the push rod can only slide in the sliding groove, and the push rod will push the positioning block to move toward the axis of the positioning ring. When the positioning ring moves, it will resist the arc rod and force the arc rod to shrink toward the inside of the positioning block. At the same time, the arc rod will compress the arc spring 2 through the circular plate. At the same time, the positioning block can also realize the inward contraction of the three groups of positioning blocks and the arc rod in the shape of a ring in equal proportion through the arc rod passing therethrough. The positioning blocks that shrink in equal proportion through the two groups of positioning rings can keep the axis centers of both ends of the pipe consistent, so as to avoid the deviation of the axis center of the pipe during polishing and cause the deviation of the polishing work.

[0015] 2. The anti-deviated polishing machine for metal tool manufacturing has three groups of positioning blocks, and the three groups of positioning blocks are arranged in a circular array. At the same time, the three groups of positioning blocks and the arc rods passing through them are in a circular ring shape. Therefore, when the positioning blocks are contracted, pipes of different diameters can be fixed. Moreover, as the polishing machine body is pressed down to fix the pipes, and the polishing machine body is lifted, the arc spring resets the turntable through the toggle plate, that is, contacts the positioning blocks to clamp the pipes, which is convenient and quick, and more convenient for debugging after the pipes are polished.

[0022] As Figures 1 - 5 shown, the present utility model provides a technical solution: a polishing machine for manufacturing metal tools that can prevent deviation, which includes a machine base 1 and a bracket 3. The inner side of the bracket 3 penetrates and is rotatably connected with a connecting frame 4. The top end of the connecting frame 4 is provided with a polishing machine body 5. When polishing the pipe in the metal tool, the pipe is inserted into the two positioning rings 21, and the pipe falls on the positioning block 215 directly below. Then, the polishing machine body 5 is started to make the polishing wheel 6 rotate. Subsequently, the polishing machine body 5 is slowly pushed, so that the position where the polishing machine body 5 is rotatably connected with the bracket 3 through the connecting frame 4 rotates. The inner side of the polishing machine body 5 is provided with a polishing wheel 6. The inner side of the machine base 1 is provided with a positioning part 2 for preventing the metal pipe from deviating during grinding. The positioning part 2 includes: a positioning ring 21, an arc-shaped groove 22, a turntable 23, a transmission groove 24, a poking plate 25, a guide rod 26, a first arc-shaped spring 27, a pressing rod 28, a fixed plate 29, a slide groove 210, a push rod 211, a slide bar 212, a slide plate 213, a return spring 214, a positioning block 215, an arc-shaped rod 216, a circular plate 217, and a second arc-shaped spring 218.

[0023] The positioning ring 21 penetrates through the machine base 1, and the positioning ring 21 is fixedly connected to the machine base 1. An arc-shaped groove 22 is formed on the side surface of the positioning ring 21. A turntable 23 is rotatably connected to the inner side of the positioning ring 21. A transmission groove 24 is formed on the surface of the turntable 23. A toggle plate 25 is fixedly connected to the side surface of the turntable 23. A guide rod 26 is fixedly connected to the inner side of the arc-shaped groove 22. The toggle plate 25 penetrates through the arc-shaped groove 22 and is slidably connected. When the connecting frame 4 rotates, it will first contact the pressing rod 28, thereby forcing the pressing rod 28 to move downward and pressing the toggle plate 25 to slide within the arc-shaped groove 22. When the toggle plate 25 slides within the arc-shaped groove 22, the first arc-shaped spring 27 will be compressed. At the same time, the toggle plate 25 will drive the turntable 23 to rotate. The toggle plate 25 is penetrated by the guide rod 26. A first arc-shaped spring 27 is fixedly connected to the surface of the toggle plate 25. One end of the first arc-shaped spring 27 away from the toggle plate 25 is fixedly connected to the inner side of the arc-shaped groove 22. A pressing rod 28 is fixedly connected to the top surface of the toggle plate 25. A fixing plate 29 is fixedly connected to the inner wall of the positioning ring 21. A sliding groove 210 is formed on the surface of the fixing plate 29. When the turntable 23 rotates, the transmission groove 24 formed on the surface of the turntable 23 will contact the sliding rod 212 located within the transmission groove 24. However, since the sliding rod 212 is fixedly connected to the push rod 211, and the push rod 211 penetrates through the sliding groove 210 and is slidably connected, the sliding groove 210 limits the push rod 211. Thus, when the sliding rod 212 is toggled by the transmission groove 24, the push rod 211 can only slide within the sliding groove 210. The push rod 211 penetrates through and is slidably connected to the inner side of the sliding groove 210.

[0024] The push rod 211 is fixedly connected to a sliding rod 212 on its surface. The sliding rod 212 penetrates the transmission groove 24. When the sliding rod 212 is moved by the transmission groove 24, the push rod 211 can only slide in the slide groove 210, and the push rod 211 will push the positioning block 215 to move toward the axis of the positioning ring 21. The push rod 211 is fixedly connected to a sliding plate 213 on its surface. The sliding plate 213 is fixedly connected to a return spring 214 on its surface. The end of the return spring 214 away from the sliding plate 213 is fixedly connected to the inner wall of the slide groove 210. One end of the push rod 211 close to the center of the positioning ring 21 is fixedly connected with a positioning block 215. When the positioning ring 21 moves, it will resist the arc rod 216 and force the arc rod 216 to shrink into the inside of the positioning block 215. At the same time, the arc rod 216 will compress the arc spring 218 through the circular plate 217. At the same time, the positioning block 215 can also pass through the arc rod 216 passing through it, so that the three groups of positioning blocks 215 and the arc rod 216 are proportionally contracted inward in a circular shape, and the positioning blocks 215 that shrink in equal proportion through the two groups of positioning rings 21 can make the axis centers of both ends of the pipe consistent. The number of positioning blocks 215 is three, and the three groups of positioning blocks 215 are arranged in a circular array with the center line of the positioning ring 21 as the axis center. The positioning block 215 and the other two groups of positioning blocks 215 are all penetrated by arc rods 216. The three groups of positioning blocks 215 and the arc rods 216 penetrated therebetween are in a circular ring shape, so that when the positioning block 215 is contracted, pipes of different diameters can be fixed, and the positioning block 215 can fix the pipes as the polishing machine body 5 is pressed down. The two ends of the arc rod 216 are fixedly connected with circular plates 217, and the surface of the circular plates 217 is fixedly connected with arc springs 218. When the slide bar 212 is moved by the transmission groove 24, the push rod 211 can only slide in the slide groove 210, and the push rod 211 will push the positioning block 215 to move toward the axis of the positioning ring 21. When the positioning ring 21 moves, it will resist the arc rod 216 and force the arc rod 216 to contract toward the inside of the positioning block 215, and the arc rod 216 will compress the arc springs 218 through the circular plates 217.

[0025] Based on the above embodiments, when polishing the pipe in the metal tool, the pipe is inserted into the two groups of positioning rings 21, and the pipe falls on the positioning block 215 directly below. Then, the polishing machine body 5 is started to make the polishing wheel 6 rotate. Subsequently, the polishing machine body 5 is slowly pushed, so that the position where the polishing machine body 5 is rotatably connected to the bracket 3 through the connecting frame 4 rotates. At this time, not only will the polishing wheel 6 slowly approach the pipe, but when the connecting frame 4 rotates, it will first contact the pressure rod 28, thereby forcing the pressure rod 28 to move downward and pressing the toggle plate 25 to slide in the arc-shaped groove 22. When the toggle plate 25 slides in the arc-shaped groove 22, it will compress the first arc-shaped spring 27. At the same time, the toggle plate 25 will drive the turntable 23 to rotate. When the turntable 23 rotates, the transmission groove 24 opened on the surface of the turntable 23 will contact the slide rod 212 located in the transmission groove 24. However, since the slide rod 212 is fixedly connected to the push rod 211, and the push rod 211 passes through the chute 210 and is slidably connected, the chute 210 limits the push rod 211. Therefore, when the slide rod 212 is toggled by the transmission groove 24, the push rod 211 can only slide in the chute 210. The push rod 211 will push the positioning block 215 towards the axis of the positioning ring 21. When the positioning ring 21 moves, it will contact the arc-shaped rod 216 and force the arc-shaped rod 216 to contract towards the inside of the positioning block 215. At the same time, the arc-shaped rod 216 will compress the second arc-shaped spring 218 through the round plate 217. At the same time, the positioning block 215 can also pass through the arc-shaped rod 216 penetrating therebetween, so that the three groups of positioning blocks 215 and the arc-shaped rod 216 contract in an equal proportion in a circular shape. And the positioning blocks 215 that contract in an equal proportion in the two groups of positioning rings 21 can keep the axes of both ends of the pipe consistent, avoiding the deviation of the pipe axis during polishing by the polishing wheel 6, which may lead to the deviation of the polishing work.

[0026] Since the number of the positioning blocks 215 is three groups, and the three groups of positioning blocks 215 are arranged in a circumferential array, and the three groups of positioning blocks 215 and the arc-shaped rod 216 penetrating therebetween together form a circular ring. Therefore, when the positioning blocks 215 contract, they can fix pipes with different diameters. Moreover, as the polishing machine body 5 presses down, the positioning blocks 215 fix the pipe, and when the polishing machine body 5 is lifted, the first arc-shaped spring 27 will reset the turntable 23 through the toggle plate 25, that is, release the clamping of the positioning blocks 215 on the pipe, which is convenient and fast, and more convenient for the debugging after the pipe is polished.

[0027] The above generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
