Description

Technical Field

[0001] This application relates to the technical field of magnetic rod processing, and particularly to a magnetic rod grinding device. Background Art

[0002] In the production and manufacturing process of magnetic rods, their two end faces are often troubled by surface defects such as scratches and burrs. These defects not only damage the aesthetic appearance of the products, but may also have an adverse impact on the performance of magnetic rods in high-end applications such as precision instruments, specifically manifested as affecting the accuracy and stability of magnetic field distribution. In order to overcome this problem and improve the overall quality of magnetic rods, the grinding process is particularly important, which can effectively improve the flatness of the two end faces of magnetic rods and ensure that the products meet the qualified quality standards.

[0003] However, currently, most traditional grinding methods are to convey magnetic rods to the grinding station one by one through a belt conveyor, and then manual intervention is required to accurately install the magnetic rods on the fixture and control the grinding equipment to complete the fine grinding operation at both ends. After grinding, manual intervention is required again to take out the finished products from the fixture and enter the next production stage. This series of manual operations is not only cumbersome, time-consuming and laborious, but also greatly limits the automation level and overall processing efficiency of the production line, increasing the production cost.

Detailed implementation manners

[0025] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where like or similar reference numerals denote like or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as limiting the present application.

[0026] The magnetic rod grinding device according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0027] As Figures 1-5 shown, the magnetic rod grinding device according to an embodiment of the present application includes a feeding mechanism 10, a loading and unloading device 20, and two grinding devices 30.

[0028] Among them, the feeding mechanism 10 and the loading and unloading device 20 are arranged side by side. The loading and unloading device 20 may include a support table 21, a workbench 22, a loading and unloading mechanism 23, a first telescopic mechanism 24, a guide block 25, and two transmission mechanisms 26.

[0029] It should be noted that both the workbench 22 and the guide block 25 described in this embodiment are made of non-magnetic materials. For example, they can be made of materials such as stainless steel or aluminum alloy.

[0030] Among them, the workbench 22 is arranged on the support table 21, and a limit groove 201 is provided on the top wall of the workbench 22. The limit groove 201 is used to place the magnetic rod to be ground, and a magnetic metal plate 202 is provided at the bottom of the limit groove 201. Two symmetrically distributed mounting grooves 203 are provided on the side wall of the workbench 22. It should be noted that the magnetic metal plate 202 described in this embodiment can be made of magnetic elements such as iron, nickel, cobalt or their alloys, and can be adsorbed by the magnetic rod, thereby avoiding the magnetic rod from shifting or rotating when grinding the end face of the magnetic rod.

[0031] The loading and unloading mechanism 23 is arranged on the workbench 22 to move up and down. The first telescopic mechanism 24 is arranged on the support table 21, and the output end of the first telescopic mechanism 24 is connected to the loading and unloading mechanism 23. Among them, the first telescopic mechanism 24 is used to drive the loading and unloading mechanism 23 to move up and down.

[0032] It should be noted that the first telescopic mechanism 24 described in this embodiment can be a cylinder, a hydraulic cylinder or an electric telescopic rod.

[0033] The guide block 25 is arranged on the side wall of the workbench 22 close to the feeding mechanism 10. Among them, the top surface of the guide block 25 is an inclined surface sloping downward, so that the magnetic rod can roll down along the inclined surface of the guide block 25 into the limit groove 201.

[0034] Two transmission mechanisms 26 are respectively arranged in the corresponding installation grooves 203, and the two transmission mechanisms 26 are respectively connected to the loading and unloading mechanism 23. Two grinding devices 30 are symmetrically distributed on both sides of the workbench 22 and are slidably connected to the support table 21, and the two grinding devices 30 are respectively connected to the corresponding transmission mechanisms 26. Among them, the grinding device 30 is used for grinding the end faces of the magnetic rods.

[0035] It should be noted that in this embodiment, the initial positions of the two grinding devices 30 are close to both ends of the workbench 22.

[0036] It can be understood that when the loading and unloading mechanism 23 moves upward, the upward moving loading and unloading mechanism 23 drives the transmission mechanism 26 to drive the grinding device 30 to move away from the workbench 22; when the loading and unloading mechanism 23 moves downward, it drives the transmission mechanism 26 to drive the grinding device 30 to move close to the workbench 22 to grind the two end faces of the magnetic rod. It should be particularly noted that when the loading and unloading mechanism 23 moves upward, it can load the magnetic rod to be ground once and unload the ground magnetic rod once. When the loading and unloading mechanism 23 moves downward, it can drive the grinding device 30 to approach the end face of the magnetic rod through the transmission mechanism 26 to grind the end face of the magnetic rod. That is, when the loading and unloading mechanism moves up and down once, it can not only complete loading and unloading, but also drive the grinding device 30 to reciprocate (that is, first move away from the workbench 22 and then move close to the workbench 22) once to grind the end face of the magnetic rod.

[0037] Furthermore, in an embodiment of the present application, as Figure 1 and Figure 2 shown, the feeding mechanism 10 may include a support frame 11, a feeding groove 12 and a baffle 13.

[0038] Among them, the support frame 11 is vertically arranged relative to the ground, the feeding groove 12 is obliquely arranged downward on the support frame 11, and the outlet end of the feeding groove 12 is attached to the side wall of the guide block 25. The baffle 13 is fixedly arranged near the discharge port of the feeding groove 12 on the feeding groove 12. Among them, both the baffle 13 and the feeding groove 12 are made of non-magnetic materials. It should be noted that the non-magnetic materials described in this embodiment may be materials such as stainless steel, aluminum alloy or plastic.

[0039] In the example of the present application, in order to facilitate the conveying of the ground magnetic rods, a discharging groove (not shown in the figure) may also be arranged on the side of the workbench 22 away from the feeding groove 12.

[0040] It should be noted that the distance between the baffle 13 and the guide block 25 described in this embodiment is equal to the diameter of the magnetic rod. It can be understood that when multiple magnetic rods are placed side by side in the feeding trough 12, there will be an adsorption situation between any two adjacent magnetic rods. When the loading and unloading mechanism 23 feeds the magnetic rod adjacent to the guide block 25, it is inevitable that the loaded magnetic rod will drive other magnetic rods to move under the action of its attraction. By setting the baffle 13, when feeding the magnetic rod located at the discharge port of the feeding trough 12, it can block the adjacent magnetic rods and prevent them from moving with the loaded magnetic rod.

[0041] Specifically, before grinding the magnetic rods, relevant staff can first transport multiple magnetic plates to be ground into the feeding trough 12 through a belt conveyor. Since the feeding trough 12 is inclined downward, the multiple magnetic rods entering the feeding trough 12 are arranged side by side in the feeding trough 12 and abut against the side wall of the guide block 25.

[0042] When the two end faces of the magnetic rod need to be ground, the staff can control the output end of the first telescopic mechanism 24 to extend and push the loading and unloading mechanism 23 to move upward, and push the magnetic rod to be ground onto the guide block 25, and roll into the limit groove 201 through the inclined plane at the top of the guide block 25. Since the bottom of the limit groove 201 is provided with a magnetic metal plate 202, the magnetic rod falling into the limit groove 201 is adsorbed on the magnetic metal plate 202 and fixed.

[0043] At the same time, the upward moving loading and unloading mechanism 23 drives the grinding device 30 to move away from the workbench 22 through the transmission mechanism 26. When the first telescopic mechanism 24 drives the loading and unloading mechanism 23 to descend, the descending loading and unloading mechanism 23 drives the grinding device 30 to move closer to the workbench 22 through the transmission mechanism 26. At this time, the staff can control the grinding device 30 to grind the end face of the magnetic rod to be ground.

[0044] When the two end faces of the magnetic rod located in the limit groove 201 are ground, the staff can control the first telescopic mechanism 24 to drive the loading and unloading mechanism 23 to move upward. At this time, the upward moving loading and unloading mechanism 23 pushes the ground magnetic rod out of the limit groove 201 for unloading. At the same time, the ascending loading and unloading mechanism 23 transports the magnetic rod to be ground onto the guide block 25 and rolls down the slope of the guide block 25 into the limit groove 201. By repeating the above steps, until the two end faces of all the magnetic rods in the feeding trough 12 are ground. It can automatically load and unload and grind, without too much manual operation, which not only reduces the burden on workers, but also improves the overall processing efficiency.

[0045] It should be particularly noted that both the first telescopic mechanism 24 and the grinding device 30 can be automatically controlled by a controller.

[0046] In an embodiment of the present application, as Figures 1-4 shown, the loading and unloading mechanism 23 may include a support plate 231, two loading plates 232, and two unloading plates 233.

[0047] Among them, the support plate 231 is arranged on the support table 21 in a lifting and moving manner, and the support plate 231 is detachably connected to the output end of the first telescopic mechanism 24. It can be understood that the first telescopic mechanism 24 described in this embodiment is detachably connected to the support plate 231, which is convenient for the installation and replacement of the first telescopic mechanism 24. For example, the first telescopic mechanism 24 can be connected to the support plate 231 by means of clamping, riveting, or connection with threaded fasteners (screws, bolts, or bolts).

[0048] The two loading plates 232 are arranged side by side and vertically on the support plate 231, and the two loading plates 232 respectively penetrate the bottom of the feeding groove 12. The two unloading plates 233 are arranged side by side and vertically on the support plate 231, and the two unloading plates 233 are distributed side by side with the two loading plates 232. Among them, the two unloading plates 233 are respectively slidably connected to the support table 21, the two unloading plates 233 respectively penetrate the limiting groove 201 and the corresponding installation groove 203, and the top surfaces of the loading plates 232 and the unloading plates 233 are both inclined surfaces slanting downward, so as to facilitate the magnetic rods to roll down along the top slopes thereof. It should be noted that one side of the top end of the loading plate 232 has a thin wall. When the loading plate 232 rises, the thin wall can be inserted between two adjacent magnetic rods, thereby separating the two adjacent magnetic rods.

[0049] It should be noted that both the loading plate 232 and the unloading plate 233 described in this embodiment are made of non-magnetic materials, such as stainless steel, aluminum alloy, or plastic.

[0050] Furthermore, in an embodiment of the present application, as Figures 1-4 shown, the transmission mechanism 26 may include two gears 261, a first rack 262, and a second rack 263.

[0051] Among them, the two gears 261 are coaxially rotatably arranged in the installation groove 203, the first rack 262 is fixedly arranged on the corresponding unloading plate 233, and the first rack 262 meshes with one of the gears 261.

[0052] The second rack 263 is horizontally and movably arranged in the workbench 22, and one end of the second rack 263 penetrates out of the workbench 22. The second rack 263 meshes with the other gear, and the second rack 263 and the first rack 262 are arranged in a cross shape.

[0053] It can be understood that when the output end of the first telescopic mechanism 24 extends and pushes the support plate 231 to drive the loading plate 232 and the unloading plate 233 to rise, the rising unloading plate 233 simultaneously drives the first rack 262 to move upward synchronously. The rising loading plate 232 pushes the magnetic rod to be polished onto the guide block 25, and the magnetic rod to be polished located on the guide block 25 is blocked by the rising unloading plate 233. At the same time, the first rack 262 moving upward drives the two gears 261 to rotate synchronously, and the rotating gears 261 drive the second rack 263 to drive the grinding device 30 to move away from the workbench 22.

[0054] When the output end of the first telescopic mechanism 24 retracts and drives the loading plate 232 and the unloading plate 233 to descend through the support plate 231, the descending unloading plate 233 retracts into the workbench 22 and releases the limit on the magnetic rod to be polished. At this time, the magnetic rod to be polished rolls down along the slope of the guide block 25 into the limit groove 201 and is adsorbed and fixed on the magnetic metal plate 202. At the same time, the descending unloading plate 233 drives the two gears 261 to rotate in the reverse direction through the first rack 262, and the rotating gears 261 drive the second rack 263 to drive the grinding device 30 to approach the end wall of the magnetic rod to be polished to polish the end of the magnetic rod to be polished.

[0055] When the output end of the first telescopic mechanism 24 extends again, the rising unloading plate 233 lifts the polished magnetic rod and separates it from the magnetic metal plate 202. When the top slope of the unloading plate 233 is higher than the workbench 22, the polished magnetic rod rolls down along the slope of the unloading plate 233, thus completing the unloading of the magnetic rod. At the same time, the rising loading plate 232 pushes the magnetic rod to be polished onto the guide block 25 for loading. By repeating the above steps repeatedly until all the magnetic rods to be polished are polished. It can automatically load and unload and grind, without too much manual operation, which not only reduces the burden on workers but also improves the overall processing efficiency.

[0056] In an embodiment of the present application, as Figures 1-3 and Figure 5 shown, the grinding device 30 may include a support base 31, a driving mechanism 32, a spline shaft 33, a spline sleeve 34, a spring 35, and a grinding head 36.

[0057] Among them, the support base 31 is slidably arranged on the support table 21, and the support base 31 is connected to one end of the corresponding second rack 263. The driving mechanism 32 is arranged on the support base 31, and the output end of the driving mechanism 32 is fixedly connected to one end of the spline shaft 33.

[0058] It should be noted that the driving mechanism 32 described in this embodiment may be a driving motor.

[0059] The spline sleeve 34 is sleeved on the spline shaft 33. The spring 35 is arranged inside the spline sleeve 34. One end of the spring 35 is fixedly connected to the end wall of the spline sleeve 34, and the other end of the spring 35 is fixedly connected to the other end of the spline shaft 33. The grinding head 36 is fixedly arranged on the end wall of the spline sleeve 34 away from the driving mechanism 32. It should be noted that the grinding head 36 described in this embodiment can be a polishing wheel.

[0060] It can be understood that by the cooperation of the spline sleeve 34 and the spline shaft 33 to drive the grinding head 36 to rotate, it can play a buffering role when the two grinding heads 36 move towards each other to grind the end wall of the magnet bar to be ground. That is, when the two grinding heads 36 moving towards each other squeeze the magnet bar, at this time, the grinding head 36 can move towards the driving mechanism 32 by compressing the spring 35 through the spline sleeve 34, thereby avoiding hard damage to the end wall of the magnet bar to be ground by the grinding head 36.

[0061] Specifically, when the grinding device 30 approaches the end wall of the magnet bar to be ground, the staff can control the driving mechanism 32 to drive the spline shaft 33 to drive the spline sleeve 34 to rotate. The rotating spline sleeve 34 drives the grinding head 36 to rotate synchronously. When the rotating grinding head 36 contacts the end wall of the magnet bar, the grinding head 36 grinds and polishes the end wall of the magnet bar.

[0062] In another embodiment of the present application, as Figure 6 and Figure 7 shown, the above-mentioned magnet bar grinding equipment may further include a cleaning device 40. The cleaning device 40 may include a support arm 41, a U-shaped frame 42, a second telescopic mechanism 43, two electromagnets 44 and two limiting mechanisms 45.

[0063] Among them, the support arm 41 is erected on the support table 21, and the support arm 41 is located above the workbench 22. The U-shaped frame 42 is arranged to move up and down between the support arm 41 and the workbench 22. The second telescopic mechanism 43 is arranged on the support arm 41, and the output end of the second telescopic mechanism 43 is detachably connected to the U-shaped frame 42. It can be understood that in this embodiment, the output end of the second telescopic mechanism 43 is detachably connected to the U-shaped frame 42, which is convenient for the installation and replacement of the second telescopic mechanism 43. For example, the second telescopic mechanism 43 can be connected to the U-shaped frame 42 by means of clamping, riveting or connecting with threaded fasteners, etc.

[0064] It should be noted that the second telescopic mechanism 43 described in this embodiment can be a cylinder, a hydraulic cylinder or an electric telescopic rod.

[0065] Two electromagnets 44 are respectively arranged at both ends of the U-shaped frame 42, and the two electromagnets 44 are respectively connected to an external power supply. Two limiting mechanisms 45 are arranged side by side on the bottom wall of the U-shaped frame 42. It should be noted that the adsorption strength of the electromagnet 44 described in this embodiment is much greater than that of the magnetic rod.

[0066] To clearly illustrate the previous embodiment, in an embodiment of the present application, as Figure 7 shown, the limiting mechanism 45 may include a support column 451, a sleeve 452 and a tension spring 453.

[0067] Among them, the support column 451 is vertically and fixedly arranged on the bottom wall of the U-shaped frame 42. The sleeve 452 is sleeved on the support column 451. The bottom end of the sleeve 452 extends to the outside of the U-shaped frame 42, and a clamping groove 4501 corresponding to the limiting groove 201 is opened at the bottom end of the sleeve 452. It should be noted that the sleeve 452 described in this embodiment can be made of plastic material.

[0068] The tension spring 453 is arranged in the sleeve 452, and one end of the tension spring 453 is fixedly connected to the end wall of the sleeve 452, and the other end of the tension spring 453 is fixedly connected to the end wall of the support column 451. It should be noted that the tension of the tension spring 453 described in this embodiment is greater than the adsorption force of the electromagnet 44.

[0069] It can be understood that when the grinding head 36 grinds and polishes the end wall of the magnetic rod, the generated magnetic debris or powder is easily adsorbed on the magnetic rod. Therefore, in order to improve the quality of the magnetic rod after grinding, the cleaning device 40 can be used to clean the impurities (debris or powder generated by grinding the magnetic rod) adsorbed on its surface.

[0070] Specifically, when the two end walls of the magnetic rod are ground and polished by the grinding head 36, the staff can control the output end of the second telescopic mechanism 43 to extend and drive the two electromagnets 44 and the two limiting mechanisms 45 to move downward synchronously through the U-shaped frame 42. The downward moving sleeve 452 is clamped on the ground magnetic rod through the clamping groove 4501.

[0071] Then, the staff controls the output end of the first telescopic mechanism 24 to extend and push the support plate 231 to drive the feeding plate 232 and the discharging plate 233 to move upward. The upward moving discharging plate 233 pushes the ground magnetic rod upward. The upward moving magnetic rod pushes the sleeve 452 upward and compresses the tension spring 453 until the two ends of the magnetic rod are opposite to the two electromagnets 44. At this time, the staff can control the electromagnet 44 to be energized and adsorb the impurities adsorbed on the magnetic rod on the electromagnet 44, thereby completing the cleaning of the magnetic rod and effectively improving the overall quality of the magnetic rod after grinding.

[0072] After the polished magnetic rod is cleaned, the staff can control the output end of the second telescopic mechanism 43 to retract and drive the sleeve 452 and the electromagnet 44 to rise and reset through the U-shaped frame 42. During the rising process, the electromagnet 44 first moves away from the cleaned magnetic rod, while the sleeve 452 abuts against the cleaned magnetic rod under the tension of the tension spring 453 until the height of the rising U-shaped frame 42 drives the sleeve 452 to completely disengage from the cleaned magnetic rod. The magnetic rod without the limit of the sleeve 452 then rolls out along the slope of the blanking plate 233, thus completing the blanking.

[0073] As a possible situation, in order to facilitate the collection of impurities adsorbed by the electromagnet 44, an electric telescopic rod (not shown in the figure) can also be provided on the side wall of the feeding trough 12, and a waste collection box (not shown in the figure) is provided on the output end of the electric telescopic rod. The staff can control the output end of the electric telescopic rod to extend and drive the waste collection box to move below the electromagnet 44.
