Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grinding equipment, in particular to an electrode wheel grinding device. Background Art
[0002] In modern hot-dip galvanizing, galvanizing, and aluminum-plating continuous production lines, the tail of a coil of steel plate and the head of the next coil need to be welded by a lap resistance seam welder to ensure continuous production of the production line. In the continuous production process, welding will become more and more frequent. The surface of the electrode wheel, which is in direct contact with the steel plate, will be heated and softened, and a black oxide layer will slowly form. This oxide layer is formed by the rolling oil and iron molecules remaining on the surface of the steel plate being squeezed at high temperature and adhered to the surface of the copper wheel. At this time, it will block the current when the electrode wheel and the steel plate are welded, resulting in loose welding. The plate may break during the production process, affecting normal production and causing economic losses. In order to avoid this situation, on the one hand, after a certain number of welding, the operator will manually grind the electrode wheel surface online to remove the oxide layer. At this time, the copper powder generated during the grinding process is likely to fall onto the welding machine and its surroundings, causing a short circuit and affecting the normal operation of the welding machine. On the other hand, the electrode wheels with oxide layers that are difficult to remove on the surface are directly replaced and taken to other offline machine tools for turning processing. This will accelerate the wear of the electrode wheel, reduce the service life of the electrode wheel, and increase production costs. Utility Model Content

[0031] like Figures 1 to 3 As shown, the utility model discloses an electrode wheel grinding device, comprising:
[0032] Working platform 1;
[0033] A fixed component is arranged on the working platform 1; a rotating device 21 is arranged on the fixed component, and the rotating device 21 drives the electrode wheel to rotate;
[0034] A grinding component, comprising a height adjustment component and a grinding sheet 32, wherein the height adjustment component is located on the working platform 1, and the grinding sheet 32 is mounted on the height adjustment component;
[0035] During grinding, the grinding sheet 32 acts on the surface of the rotating electrode wheel.
[0036] Compared with the prior art, the electrode wheel grinding device provided by the utility model can be applied to electrode wheels of various sizes and specifications, and has high applicability. When the electrode wheel needs to be ground, the electrode wheel is disassembled on the production line and then placed on the electrode wheel grinding device for grinding, and the online grinding is changed to the offline grinding method, which effectively prevents the ground copper powder from being scattered in the welding machine of the production line and affecting the normal operation of the welding machine; when using the electrode wheel grinding device, the electrode wheel is installed on the rotating device 21, and the height of the grinding sheet 32 is adjusted by the height adjustment component, so that the grinding sheet 32 keeps in contact with the surface of the electrode wheel, effectively controlling the depth and quality of the electrode wheel grinding, extending the service life of the electrode wheel, and thus effectively controlling the loss cost of the electrode wheel.
[0037] In one embodiment, the rotating device 21 is a pneumatic motor; the electrode wheel grinding device also includes a manual reversing valve 4, which is installed on the working platform 1, and the manual reversing valve 4 is respectively connected to the external air source and the pneumatic motor, and is used to control the rotation direction of the pneumatic motor. The electrode wheel is ground by the forward and reverse rotation of the pneumatic motor through the manual reversing valve 4, so as to control the quality of the electrode wheel grinding, and also facilitate the user's operation.
[0038] Furthermore, a speed regulating valve is connected to the pneumatic motor to adjust the rotation speed of the pneumatic motor and further adjust the rotation speed of the electrode wheel.
[0039] In one embodiment, the fixing component includes a rotating seat 22 and a fixed seat 23; a rotatable gear shaft 24 is provided on the rotating seat 22; the electrode wheel is fixed on the gear shaft 24; the rotating device 21 is installed on the fixed seat 23, and the driving end of the rotating device 21 is connected to the first gear 25; a second gear 26 is rotatably provided on the outer side of the fixed seat 23, the first gear 25 is meshed with the second gear 26, and the second gear 26 is meshed with the gear shaft 24, and the rotating device 21 drives the gear shaft 24 to rotate through the first gear 25 and the second gear 26, thereby driving the electrode wheel to rotate.
[0040] Furthermore, the diameter of the first gear 25 is smaller than the diameter of the second gear 26; the diameter of the second gear 26 is smaller than the diameter of its gear on the gear shaft 24. Through the cooperation of these three small, medium and large gears, a deceleration effect can be achieved, the torque on the gear shaft 24 can be increased, and the workload of the rotating device 21 can be reduced.
[0041] In one embodiment, the height adjustment assembly includes a support 311 and a pressure rod 312; one end of the pressure rod 312 is rotatably connected to the support 311, and the grinding sheet 32 is mounted on the pressure rod 312. When in use, the user adjusts the height of the grinding sheet 32 by rotating the pressure rod 312, so that the height of the grinding sheet 32 can be flexibly changed, which is suitable for electrode wheels of different sizes, and has simple operation and high applicability.
[0042] Furthermore, the electrode wheel grinding device also includes a pressing component, which is connected to the pressure rod 312; when grinding, the pressing component acts on the pressure rod 312 to keep the grinding sheet 32 in contact with the electrode wheel. During grinding, due to the action of the pressing component, the grinding sheet 32 is always in contact with the electrode wheel, which can free the user's hands and reduce the workload.
[0043] Furthermore, the pressing component includes a spring 8, one end of the spring 8 is hooked on the working platform 1, and the other end is hooked on the pressing rod 312. When the spring 8 is hooked on the working platform 1 and the pressing rod 312 at the same time, the spring 8 is in a stretched state. After the grinding sheet 32 contacts the wheel surface of the electrode wheel 7, the spring 8 is pulled up by hand to hook on the pressing rod 312, and the pressing rod 312 is continuously pressed and polished by using the tension of the spring 8, so that the operator can free his hands and reduce the workload.
[0044] It should be noted that, according to actual conditions, the present invention may not use a pressing component, but may manually press the pressing rod 312 to perform the grinding work.
[0045] Furthermore, the electrode wheel grinding device also includes a guide seat 61, a guide shaft 62 and a rocking shaft 63. The guide seat 61 is installed on the working platform 1. The guide shaft 62 is movably arranged in the guide seat 61 and moves up and down along the guide seat 61. The diameter of the rocking shaft 63 is smaller than the diameter of the guide shaft 62. One end of the rocking shaft 63 is rotatably connected to the guide shaft 62 through a pin shaft 64, and the other end is rotatably connected to the pressure rod 312 through a pin shaft 64. When the pressure rod 312 is pressed down or pulled up, since the swing shaft 63 is rotatably connected to the pressure rod 312, the swing shaft 63 will swing at a certain angle along the length direction of the pressure rod 312, thereby driving the guide shaft 62 located in the guide seat 61 to slide up and down in the guide seat 61; and positioning through this guide shaft 62 can prevent the pressure rod 312 from swinging back and forth significantly along the axial direction of the electrode wheel 7 when the electrode wheel 7 is rotating and grinding, thereby effectively preventing the grinding plate 32 from moving axially and detaching from the electrode wheel 7.
