Description

Technical Field

[0001] The utility model relates to the technical field of polishing machines, and specifically relates to an automatic polishing machine for fastener production. Background Technique

[0002] Due to the irregularity of the surface of the fastener, when polishing it, common grinding and polishing are not used. Instead, a magnetic polishing machine that can completely polish the outer surface of the fastener is used. The magnetic polishing machine is a device that uses the power of a magnetic field to guide abrasive materials (such as magnetic needles) to perform rapid rotational motion, thereby efficiently grinding and polishing the fastener. It can handle problems such as burrs, oxide films, and rust on the surface of the fastener, making the surface of the fastener smooth and bright. The working principle of the magnetic polishing machine mainly relies on the drive of a strong magnetic field on the magnetic needle, causing the magnetic needle to rotate at high speed and rub on the surface of the workpiece, thereby achieving the purpose of polishing. And this kind of magnetic polishing machine that can polish the fastener can be called an automatic polishing machine for fastener production.

[0003] However, when using this automatic polishing machine for magnetic fastener production, it is necessary to pour the magnetic needles and the fasteners to be polished into the inside of the grinding barrel together, and then make the magnetic needles rotate through the magnetic field. After the grinding is completed, since the fasteners and the magnetic needles are mixed together inside the grinding barrel, only the fasteners can be manually picked out one by one from a large number of magnetic needles. The operation is relatively cumbersome and the feeding efficiency is low. Therefore, it does not meet the existing requirements, and for this reason, we propose an automatic polishing machine for fastener production. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automatic polishing machine for fastener production to solve the problems mentioned in the above background technique. When using this automatic polishing machine for magnetic fastener production, it is necessary to pour the magnetic needles and the fasteners to be polished into the inside of the grinding barrel together, and then make the magnetic needles rotate through the magnetic field. After the grinding is completed, since the fasteners and the magnetic needles are mixed together inside the grinding barrel, only the fasteners can be manually picked out one by one from a large number of magnetic needles. The operation is relatively cumbersome and the feeding efficiency is low.

[0005] To achieve the above object, the present utility model provides the following technical solutions: An automatic polishing machine for fastener production, including an electromagnetic polishing machine, on the upper end surface of which a fastener screening mechanism is installed. The fastener screening mechanism includes a polishing tube, a coarse-hole filter screen, two tube caps, two metal limiting tubes and a rotating mechanism. The coarse-hole filter screen is located in the middle of the interior of the polishing tube. The two metal limiting tubes are respectively located above and below the coarse-hole filter screen. The outer surface of the metal limiting tube fits with the inner wall of the polishing tube. The surface of the metal limiting tube facing the coarse-hole filter screen fits with the coarse-hole filter screen. The upper end surface of the metal limiting tube above the coarse-hole filter screen and the lower end surface of the metal limiting tube below the coarse-hole filter screen are both fixedly connected with tube caps fixed to the outer surface of the polishing tube by buckles. Through the rotating mechanism, the polishing tube can be first moved upward and then rotated 180 degrees.

[0006] Preferably, the rotating mechanism includes two single-rod cylinders. The piston rod of the single-rod cylinder is connected with a lifting plate. The surface of the lifting plate facing the polishing tube is connected with a rotating shaft, and the surface of the rotating shaft facing the polishing tube is fixed to the polishing tube.

[0007] Preferably, a rotating motor is fixedly installed on the rear end surface of the second lifting plate from left to right. The output shaft of the rotating motor is connected with a transmission rotating shaft through a coupling, and the front end surface of the transmission rotating shaft is fixed to the rear end surface of the second rotating shaft from left to right.

[0008] Preferably, a bevel positioning groove is provided at the middle position of the upper and lower end surfaces of the rotating shaft. A bevel positioning block is clamped inside the bevel positioning groove, and both sides of the inner wall of the bevel positioning groove and both sides of the outer surface of the bevel positioning block are inclined surfaces.

[0009] Preferably, a receiving groove is provided on the outer side of the bevel positioning block. A positioning spring is provided inside the receiving groove. Both ends of the positioning spring are respectively connected with the inner wall of the receiving groove and the outer surface of the bevel positioning block.

[0010] Preferably, a handle is fixedly installed at the middle position of the upper and lower end surfaces of the coarse-hole filter screen, and the coarse-hole filter screen and the handle are fixed by screws.

[0011] Preferably, a magnet electric coil platform is provided below the fastener screening mechanism. The magnet electric coil platform is fixedly installed on the outer surface of the electromagnetic polishing machine by screws.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] 1. The utility model can uniformly store the polished fasteners on the upper end face of the coarse-hole filter screen through the fastener screening mechanism. When the operator removes the coarse-hole filter screen, the fasteners accumulated on its upper end face will be removed together. Through the above solution, the fasteners can be picked out from the inside of the polishing pipe more conveniently and quickly, increasing the convenience of the equipment.

[0014] 2. When the rotating motor drives the polishing pipe connected to the rotating shaft to rotate through the rotating shaft, the inclined positioning block stuck inside the inclined positioning groove on the outer surface of the rotating shaft will be pushed outwards and press the positioning spring. When the rotating shaft rotates 180 degrees, the two inclined positioning grooves will move to the positions corresponding to the two inclined positioning blocks again. Then, through the reaction force of the compressed positioning spring, the inclined positioning block can be stuck into the inclined positioning groove again to complete the positioning of the rotating shaft and the polishing pipe fixed to the rotating shaft. Through the above technical solution, the accuracy of this fastener screening mechanism is ensured. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] The electromagnetic polishing machine 1 (model number KT-185), rotating motor 9 (model number 51K90GN-YF), and positioning spring 13 (model number JX110) mentioned in the present utility model can be purchased from the market or customized privately.

[0022] Please refer to Figures 1 to 4 Figures 1 to 4 An embodiment provided by the present utility model: An automatic polishing machine for fastener production, including an electromagnetic polishing machine 1, a fastener screening mechanism is installed on the upper end surface of the electromagnetic polishing machine 1. The fastener screening mechanism includes a polishing tube 2, a coarse-hole filter screen 7, two tube caps 3, two metal limiting tubes 8 and a rotating mechanism. The coarse-hole filter screen 7 is located at the middle position inside the polishing tube 2. The two metal limiting tubes 8 are respectively located above and below the coarse-hole filter screen 7. The outer surface of the metal limiting tube 8 is attached to the inner wall of the polishing tube 2. The surface of the metal limiting tube 8 facing the coarse-hole filter screen 7 is attached to the coarse-hole filter screen 7. The upper end surface of the metal limiting tube 8 located above the coarse-hole filter screen 7 and the lower end surface of the metal limiting tube 8 located below the coarse-hole filter screen 7 are both fixedly connected with tube caps 3 fixed to the outer surface of the polishing tube 2 through buckles. Through the rotating mechanism, the polishing tube 2 can be first moved upward and then rotated 180 degrees.

[0023] Below the fastener screening mechanism is provided with a magnetoelectric coil platform 14, and the magnetoelectric coil platform 14 is fixedly installed on the outer surface of the electromagnetic polishing machine 1 through screws; when the equipment needs to be used, move the equipment to the corresponding area and connect the power supply. When the fasteners need to be polished, remove the tube cap 3 installed on the upper end surface of the polishing tube 2, and take down this tube cap 3 and the metal limiting tube 8 fixed to the lower end surface of this tube cap 3 from the polishing tube 2. When the metal limiting tube 8 in contact with the upper end surface of the coarse-hole filter screen 7 is taken down, the coarse-hole filter screen 7 can be taken out from the inside of the polishing tube 2. After the coarse-hole filter screen 7 is taken out, pour the fasteners to be polished and the steel needles into the inside of the polishing tube 2 together. The fasteners and steel needles poured into the inside of the polishing tube 2 will be blocked by the tube cap 3 installed on the lower end surface of the polishing tube 2, so as to stay inside the polishing tube 2. Then install the coarse-hole filter screen 7 and the removed tube cap 3 and metal limiting tube 8 back to their original positions. Then, make the steel needles located inside the polishing tube 2 rotate through the magnetoelectric coil platform 14 to polish the fasteners.

[0024] The rotating mechanism includes two single-rod cylinders 6. The piston rod of the single-rod cylinder 6 is connected with a lifting plate 5. The surface of the lifting plate 5 facing the polishing tube 2 is connected with a rotating shaft 4, and the surface of the rotating shaft 4 facing the polishing tube 2 is fixed to the polishing tube 2; when the polishing of the fasteners is completed, first start the single-rod cylinder 6. Through the single-rod cylinder 6, the lifting plate 5 and the polishing tube 2 connected to the lifting plate 5 through the rotating shaft 4 can be pushed upward until the tube cap 3 installed on the lower end surface of the polishing tube 2 and the magnetoelectric coil platform 14 maintain a distance of more than half of the height of the polishing tube 2, so as to provide space for the rotation of the polishing tube 2 through the above technical solution.

[0025] The rear end face of the second lifting plate 5 counted from left to right is fixedly installed with a rotary motor 9. The output shaft of the rotary motor 9 is connected with a transmission rotating shaft 10 through a coupling, and the front end face of the transmission rotating shaft 10 is fixed to the rear end face of the second rotating shaft 4 counted from left to right; when the polishing pipe 2 is moved to the corresponding height, the rotary motor 9 is started, and the rotary motor 9 can drive the polishing pipe 2 connected thereto through the transmission rotating shaft 10 and the rotating shaft 4 to rotate. When the polishing pipe 2 rotates 180 degrees, the upper and lower ends of the polishing pipe 2 will be swapped accordingly. During the rotation of the polishing pipe 2, the steel needles originally located on the lower side inside the polishing pipe 2 will pass through the coarse-hole filter screen 7, while the fasteners with larger volumes will stay on the outer surface of the coarse-hole filter screen 7. After the upper and lower end faces of the polishing pipe 2 are swapped, the pipe cap 3 moved to the upper end face of the polishing pipe 2 and the metal limit pipe 8 fixed thereto are removed, and then the coarse-hole filter screen 7 with fasteners on the upper end face can be taken out from the inside of the polishing pipe 2. Through the above solution, the fasteners located inside the polishing pipe 2 can be uniformly collected on the outer surface of the coarse-hole filter screen 7 and taken out at one time, so that the fasteners can be more conveniently and quickly taken out from the inside of the polishing pipe 2, increasing the convenience of the equipment.

[0026] At the middle positions of the upper and lower end faces of the rotating shaft 4, there is a bevel positioning groove 11 respectively. A bevel positioning block 12 is clamped inside the bevel positioning groove 11, and both sides of the inner wall of the bevel positioning groove 11 and both sides of the outer surface of the bevel positioning block 12 are inclined surfaces; an accommodation groove 16 is provided on the outer side of the bevel positioning block 12, and a positioning spring 13 is arranged inside the accommodation groove 16. The two ends of the positioning spring 13 are respectively connected to the inner wall of the accommodation groove 16 and the outer surface of the bevel positioning block 12; when the rotary motor 9 drives the polishing pipe 2 connected to the rotating shaft 4 to rotate through the rotating shaft 4, the bevel positioning block 12 clamped inside the bevel positioning groove 11 on the outer surface of the rotating shaft 4 will be pushed outwards and the positioning spring 13 will be compressed. When the rotating shaft 4 rotates 180 degrees, the two bevel positioning grooves 11 will move to the positions corresponding to the two bevel positioning blocks 12 again, and then through the reaction force of the compressed positioning spring 13, the bevel positioning block 12 can be clamped into the bevel positioning groove 11 again to complete the positioning of the rotating shaft 4 and the polishing pipe 2 fixed to the rotating shaft 4. Through the above technical solution, the accuracy of this fastener screening mechanism is ensured.

[0027] At the middle positions of the upper and lower end faces of the coarse-hole filter screen 7, a handle 15 is fixedly installed respectively, and the coarse-hole filter screen 7 and the handle 15 are fixed by screws; through the handle 15, the coarse-hole filter screen 7 can be picked up more conveniently.
