Description

Technical Field

[0001] The invention relates to the technical field of polishing, in particular to a polishing device used for producing solenoid valves. Background Art

[0002] Solenoid valves are industrial equipment controlled by electromagnetics. They are basic automation components used to control fluids. They are actuators and are not limited to hydraulic or pneumatic. They are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, and the accuracy and flexibility of the control can be guaranteed. There are many types of solenoid valves, and different solenoid valves play a role in different positions in the control system. The most commonly used ones are check valves, safety valves, directional control valves, speed regulating valves, etc.

[0004] At present, the internal parts of the solenoid valve need to be strictly polished. When polishing the cross section of a cylindrical workpiece, dust, residue and debris left over from the polishing of the previous workpiece or floating in the air often adhere to the surface of the workpiece to be polished, and a large amount of them are piled up on the workpiece to be polished in the factory. A large amount of residue will also adhere due to processing in the factory, which will affect the polishing accuracy of the polished surface and cause scratches. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a polishing device for use in the production of solenoid valves, thereby achieving the purpose of solving the above-mentioned problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A polishing device for solenoid valve production, comprising a workbench, a fixed seat is fixedly connected to the top of the workbench, a motor is fixedly connected to the outer wall of the fixed seat, an electric lifting rod is fixedly connected to the bottom of the motor, a sanding wheel is fixedly connected to the bottom of the electric lifting rod, and a residue removal mechanism is arranged outside the sanding wheel;

[0007] The residue removal mechanism comprises:

[0008] A fixed plate, which is a circular disc-shaped structure, has an outer wall with a groove, and a telescopic rod A is fixedly connected to the top of the fixed plate, and is used to rise and fall synchronously with the sanding wheel;

[0009] The bearing is a circular ring structure, the inner wall of the bearing is rotatably connected to the outer wall of the sanding wheel, the outer wall of the bearing is fixedly connected to the inner wall of the fixed plate, the top of the sanding wheel is fixedly connected with a fan blade, and the bearing is used to connect the sanding wheel and the fixed plate.

[0010] Preferably, a circular hole is opened on the inner wall of the workbench, a connecting plate is fixedly connected to the inner wall of the circular hole, a circular plate is fixedly connected to one end of the connecting plate, and a polishing material is fixedly installed on the top of the circular plate, so as to perform fixed polishing.

[0011] Preferably, a telescopic rod B is fixedly connected to the inner wall of the circular hole, one end of the telescopic rod B is fixedly connected to a slider, the slider is slidably connected to the inner wall of the long slide groove, the long slide groove is opened on the inner wall of the long board B, and the top of the long board B is slidably connected to the long board A.

[0012] Preferably, a rolling ball is rotatably connected to the top of the long board A, a lifting plate is fixedly connected to the outer wall of the long board B, a fixing rod is slidably connected to the inner wall of the lifting plate, and one end of the fixing rod is fixedly connected to the bottom of the workbench, thereby being connected to each other.

[0013] Preferably, the lifting plate and the lower end of the fixing rod are magnetic, and the magnetism of the lifting plate and the lower end of the fixing rod on the side close to each other is that like poles repel each other, thereby repelling each other and moving away from each other.

[0014] Preferably, the inner wall of the long board A is fixedly connected with bristles, the bristles are elastic and made of rubber material, and the outer wall of the long board B is provided with an expansion mechanism, so as to clean by the bristles.

[0015] Preferably, the expansion mechanism comprises a square plate B, an outer wall of the square plate B is fixedly connected to an outer wall of the long plate B, and the outer wall of the square plate B is fixedly connected to the square plate A.

[0016] Preferably, the outer wall of the square plate A is fixedly connected with a spring, one end of which is fixedly connected to the outer wall of the long plate A, and the outer wall of the square plate A is fixedly connected with a pull rope, one end of which is fixedly connected to the outer wall of the long plate A, thereby being fixedly connected.

[0017] The present invention provides a polishing device for solenoid valve production, which has the following beneficial effects:

[0018] 1. The present invention overcomes the repulsive force of the same poles between the lifting plate and the lower end of the fixed rod by arranging a residue removal mechanism, so that as the long plate A descends, the bristles on the outer wall of the long plate A can be driven to continuously move and wipe the surface of the placed polishing material, completing the pre-cleaning work before polishing the surface of the polishing material, thereby avoiding the presence of residues and dust during polishing of the surface of the polishing material, resulting in a decrease in polishing accuracy and scratches caused by fine sand particles and dust during the polishing process. At the same time, a large number of sparks generated by polishing are blocked by a large number of vertical long plates A to prevent sparks mixed with residues from flying out and causing danger to surrounding staff.

[0019] 2. The present invention provides a residue removal mechanism. When the sanding wheel rotates for grinding, the rotating sanding wheel will also drive the fan blades to rotate synchronously, so that the long plate A and the surface of the bristles are blown by the rapid rotation of the fan blades, thereby completing the real-time self-cleaning of the long plate A and the bristles, avoiding the problem of a large amount of residue adhering to the surface of the polishing material after the bristles have been cleaning the surface of the polishing material for a long time, and reducing the problem of spark residues splashing and adhering to the outer wall of the long plate A. Through self-cleaning, the problem of a large amount of residue accumulation falling onto the next polishing material, resulting in a decrease in polishing accuracy, is reduced.

[0020] 3. The present invention sets an expansion mechanism, which will cause many long plates A and B to rise rapidly, and wrap around the outside of the fixed plate and contact with the fixed plate, so that each bristle on the outer wall of long plate A will pass through the inner wall of the groove opened inside the fixed plate, and be moved by the groove. The elastic force of the bristles themselves will bend from the groove and rebound back to the right position, thereby completing the self-cleaning of the bristles. At the same time, as long plates A and long plates B rebound and rise rapidly, the bristles will be vibrated, and the adhered residue will be further shaken off, thereby ensuring its efficient self-cleaning effect.

[0021] 4. The present invention sets an expansion mechanism. When the fixed plate rises to the top of the ball, the ball loses the force pushed by the fixed plate and comes to the bottom of the fixed plate. As a result, the elastic force of the spring returns the long plate A to its original position and is pulled by the pull rope to limit the position. When the long plate A is reset, real-time lateral vibration is generated, and the bristles on the outer wall of the long plate A are quickly shaken to complete the automatic self-cleaning after polishing and shake off the adhered residue. This can avoid as much as possible the problem of the bristles falling on the surface of the next polishing material due to the fanning and stirring of the fixed plate and the blades for cleaning. This minimizes the situation where the current stains are left on the next polishing material, and also ensures the stability of the polishing precision control of the polishing material and reduces scratches.

DETAILED DESCRIPTION Embodiment 1

[0034] See also Figure 1-3The present invention provides a technical solution: a polishing device for solenoid valve production, comprising a workbench 1, a fixing seat 6 is fixedly connected to the top of the workbench 1, a motor 2 is fixedly connected to the outer wall of the fixing seat 6, an electric lifting rod 5 is fixedly connected to the bottom of the motor 2, a sanding wheel 7 is fixedly connected to the bottom of the electric lifting rod 5, and a residue removal mechanism 3 is arranged outside the sanding wheel 7;

[0035] The residue removal mechanism 3 comprises:

[0036] The fixing plate 302 is a circular disc-shaped structure, the outer wall of the fixing plate 302 is provided with a groove 303, the top of the fixing plate 302 is fixedly connected with a telescopic rod A301, and the fixing plate 302 is used to play the role of synchronous lifting and lowering with the sanding wheel 7;

[0037] The bearing 304 is a circular ring structure. The inner wall of the bearing 304 is rotatably connected to the outer wall of the sanding wheel 7. The outer wall of the bearing 304 is fixedly connected to the inner wall of the fixed plate 302. The top of the sanding wheel 7 is fixedly connected with a fan blade 305. The bearing 304 is used to connect the sanding wheel 7 and the fixed plate 302.

[0038] The motor 2 is started to control the electric lifting rod 5 to rotate. When the electric lifting rod 5 rotates, the sanding wheel 7 is driven to rotate synchronously. At the same time, the electric lifting rod 5 is started to rise and fall, and the sanding wheel 7 is pushed down to the surface of the polishing material 8, so that the surface of the polishing material 8 is polished by the bottom of the fast-rotating sanding wheel 7, and the polishing work of the cross section of the polishing material 8 is completed;

[0039] When the rapidly rotating sanding wheel 7 is lowered to polish the surface of the polishing material 8, the fixed plate 302 on the outer wall of the sanding wheel 7 is fixed by the telescopic rod A301, and the fixed plate 302 is rotatably connected to the sanding wheel 7 by the bearing 304, so the rotating sanding wheel 7 will not affect the fixed plate 302, and the fixed plate 302 is also fixed and maintained by the telescopic rod A301, and when the sanding wheel 7 is raised or lowered, the telescopic rod A301 will also extend or retract itself to ensure that the fixed plate 302 can normally follow the sanding wheel 7 to rise or fall synchronously; Embodiment 2

[0040] See also Figure 1-8 On the basis of the first embodiment, the present invention provides a technical solution: a circular hole is opened on the inner wall of the workbench 1, a connecting plate 307 is fixedly connected to the inner wall of the circular hole, a circular plate 306 is fixedly connected to one end of the connecting plate 307, and a polishing material 8 is fixedly installed on the top of the circular plate 306.

[0041] A telescopic rod B315 is fixedly connected to the inner wall of the circular hole, one end of the telescopic rod B315 is fixedly connected to a slider 314, the slider 314 is slidably connected to the inner wall of the long slide groove 316, the long slide groove 316 is opened on the inner wall of the long board B311, and the long board A309 is slidably connected to the top of the long board B311.

[0042] The top of the long board A309 is rotatably connected to a rolling ball 308, the outer wall of the long board B311 is fixedly connected to a lifting plate 312, the inner wall of the lifting plate 312 is slidably connected to a fixing rod 313, and one end of the fixing rod 313 is fixedly connected to the bottom of the workbench 1.

[0043] The lower ends of the lifting plate 312 and the fixing rod 313 are magnetic, and the magnetism of the lower ends of the lifting plate 312 and the fixing rod 313 that are close to each other is that the same poles repel each other.

[0044] The inner wall of the long board A309 is fixedly connected with bristles 310, the bristles 310 are elastic and made of rubber, and the outer wall of the long board B311 is provided with an expansion mechanism 4;

[0045] The descending fixed plate 302 will touch the rolling ball 308 and push the rolling ball 308, so that the long plate A309 and the long plate B311 descend synchronously, and the long plate B311 slides and descends on the outer wall of the fixed rod 313 through the lifting plate 312, and overcomes the repulsive force of the same poles between the lifting plate 312 and the lower end of the fixed rod 313, so that as the long plate A309 descends, the bristles 310 on the outer wall of the long plate A309 can be driven to continuously move and wipe the surface of the placed polishing material 8, completing the pre-cleaning work before polishing the surface of the polishing material 8, thereby avoiding the residue and dust when polishing the surface of the polishing material 8, resulting in the reduction of polishing accuracy and scratches caused by fine sand particles and dust during the polishing process, and at the same time, a large number of sparks generated by polishing are blocked by many vertical long plates A309 to prevent sparks mixed with residues from flying out and causing danger to surrounding staff;

[0046] When the sanding wheel 7 rotates and grinds, the rotating sanding wheel 7 also drives the fan blades 305 to rotate synchronously, so that the long plate A309 and the surface of the bristles 310 are blown by the rapid rotation of the fan blades 305, thereby completing the real-time self-cleaning of the long plate A309 and the bristles 310, avoiding the problem of a large amount of residue adhering to the surface of the polishing material 8 after the bristles 310 have been cleaning the surface for a long time, and also reducing the problem of spark residues splashing and adhering to the outer wall of the long plate A309. Through its self-cleaning, the problem of a large amount of residues accumulating and falling onto the next polishing material 8, resulting in a decrease in polishing accuracy, is reduced;

[0047] When the fixed plate 302 descends and pushes the rolling ball 308 to synchronously descend with the long plate A309, the long plate B311 and the lifting plate 312, the lifting plate 312 slides and descends on the outer wall of the fixed rod 313, and the lower part of the fixed rod 313 is in an oblique shape, so when the lifting plate 312 slides and descends to the oblique position on the outer wall of the fixed rod 313, it will continue to slide down along the inclined shape under the fixed rod 313, and at this time, the slider 314 in the long slide groove 316 opened on the inner wall of the long plate B311 will be fixed by the telescopic rod B315, so as to limit the long plate B311, prevent the long plate B311 and the long plate A309 from deflecting themselves, maintain the vertical lifting movement of the long plate B311 and the long plate A309, and the length of the telescopic rod B315 can be extended and retracted, so that when the long plate B311 and the lifting plate 312 slide away from the original position on the outer wall of the fixed rod 313, their normal operation can be ensured by the extension and retraction of the telescopic rod B315; Embodiment 3

[0048] See also Figure 1-11 On the basis of the first and second embodiments, the present invention provides a technical solution: the expansion mechanism 4 includes a square plate B403, the outer wall of the square plate B403 is fixedly connected to the outer wall of the long plate B311, and the outer wall of the square plate B403 is fixedly connected to the square plate A402.

[0049] The outer wall of the square plate A402 is fixedly connected with a spring 401, one end of the spring 401 is fixedly connected with the outer wall of the long plate A309, the outer wall of the square plate A402 is fixedly connected with a pull rope 404, one end of the pull rope 404 is fixedly connected with the outer wall of the long plate A309;

[0050] When the lifting plate 312 descends to the bend of the fixed rod 313 and continues to move downward, the lifting plate 312, the long plate B311 and the long plate A309 will start to move away from the center of the sanding wheel 7 and expand outward. At this time, the ball 308 on the long plate A309 will start to roll outward at the bottom of the fixed plate 302 until it is separated from the outer edge of the fixed plate 302. Once separated from the outer edge of the fixed plate 302, the ball 308 loses the downward pressure of the fixed plate 302, so that the repulsive force between the lifting plate 312 and the lower end of the fixed rod 313 will push it up. When the long plate B311 is pushed up, The lifting plate 312 will slide up from the inclined bend of the fixed rod 313 to a vertical position. At this time, the long plate B311 will move closer to the center of the sanding wheel 7 during the process of rising, and the long plate A309 slidably connected to the long plate B311 cannot move closer to the center because it is supported by the fixed plate 302, so that the long plate A309 and the bristles 310 begin to slide against each other. When the long plate B311 drives the square plate B403 to move closer to the center, the long plate A309 will slide obliquely upward on the surface of the square plate B403 and squeeze the spring 401 to deform it. Under normal circumstances, the long plate A309 cannot slide downward because it is pulled by the pull rope 404.

[0051] At this time, many long plates A309 and long plates B311 will rise rapidly, and wrap around the outside of the fixed plate 302, and contact the fixed plate 302, so that each bristle 310 on the outer wall of the long plate A309 will pass through the inner wall of the groove 303 opened inside the fixed plate 302, and thus be moved by the groove 303, and the bristles 310 will be bent from the groove 303 and rebound back to the normal position through their own elastic force, thereby completing the self-cleaning of the bristles 310. At the same time, as the long plates A309 and the long plates B311 rebound and rise rapidly, the bristles 310 will be vibrated, and the adhered residues will be further shaken off, thereby ensuring its efficient self-cleaning effect.

[0052] After the sanding wheel 7 finishes grinding and polishing the surface of the polishing material 8, it rises. As the fixed plate 302 rises to the top of the ball 308, the ball 308 loses the force pushed by the fixed plate 302 and comes to the bottom of the fixed plate 302, so that the elastic force of the spring 401 will return the long plate A309 to its original position and be pulled by the pull rope 404 for limiting. When the long plate A309 is reset, real-time lateral vibration will be generated, and the bristles 310 on the outer wall of the long plate A309 will be quickly shaken to complete the automatic self-cleaning after polishing and shake off the adhered residue. This can avoid as much as possible the problem of the bristles 310 falling on the surface of the next polishing material 8 due to the fanning and stirring of the fixed plate 302 and the fan blades 305 next time, thereby minimizing the situation where the current stains are left on the next polishing material 8, and also ensuring the stability of the polishing accuracy control of the polishing material 8 and reducing scratches.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
