Description

Technical Field

[0001] This utility model relates to the technical field of zinc oxide resistor sheet equipment, specifically a zinc oxide resistor sheet grinding device. Background Technology

[0002] Zinc oxide resistors are made of zinc oxide material and have high resistance and power capacity. Their resistance value can be selected according to different needs, generally ranging from a few ohms to hundreds of kiloohms. In circuits, zinc oxide resistors can play roles such as regulating current, reducing voltage, voltage division, and current limiting. During the production process, defects on the surface of zinc oxide resistors caused by air and small particles in the air affect the quality of the zinc oxide resistors and require polishing.

[0003] Most zinc oxide resistance sheet grinding devices on the market grind zinc oxide resistance sheets manually. The quality of manual grinding is unstable, and it is easy to over-grind or under-grind, which brings inconvenience to people using zinc oxide resistance sheet grinding devices. Utility Model Content

[0004] The purpose of this invention is to provide a zinc oxide resistor grinding device to solve the problems mentioned in the background art, such as the unstable quality of manual grinding of zinc oxide resistors, which easily leads to over-grinding or under-grinding. To achieve the above objective, this invention provides the following technical solution: a zinc oxide resistor grinding device, including a base, the front of the top of the base being fixedly connected to the back of a rotating mechanism, the outer wall of the bottom of the rotating mechanism being movably engaged with the inner wall of the top of the grinding mechanism, and the bottom of the rotating mechanism being movably abutting against the top of a fixed mechanism.

[0005] The bottom of the fixing mechanism is movably abutted against the top of the clamping mechanism, and the bottom of the fixing mechanism is fixedly connected to the top of the base.

[0006] Preferably, the base includes a base, a grinding base plate, a fixed seat, a column, a lifting connecting rod, and a rotating handle. The top of the base near the front is fixedly connected to the bottom of the grinding base plate, and the top of the grinding base plate is fixedly connected to the bottom of the fixed seat. The top of the back of the base is fixedly connected to the bottom of the column, and one side of the column is rotatably connected to one side of the lifting connecting rod. The outer wall of the lifting connecting rod is fixedly connected to one side of the rotating handle.

[0007] Preferably, the rotating mechanism consists of a crossbeam, a rotating motor, and a rotating rod. The back of the crossbeam is fixedly connected to the front of the top of the column, and the top of the crossbeam is movably engaged with the bottom of the rotating motor. The bottom of the rotating motor is fixedly connected to the top of the rotating rod via a coupling. A crossbeam through hole is provided near the top of the front of the crossbeam, and the inner wall of the crossbeam through hole is rotatably connected to the outer wall of the top of the rotating rod.

[0008] Preferably, the grinding mechanism includes a grinding mounting shaft, a grinding side plate, and a grinding base plate. The inner wall of the top of the grinding mounting shaft is movably engaged with the outer wall of the bottom of the rotating rod, and the inner wall of the bottom of the grinding mounting shaft is movably engaged with the outer wall of the grinding side plate. The bottom of the grinding mounting shaft is movably engaged with the top of the grinding base plate.

[0009] Preferably, the fixing mechanism consists of a movable pressure rod, a fixed mounting block, and a fixed mounting ring. The top of the movable pressure rod is movably abutted against the bottom of the rotating rod, and the outer wall of the movable pressure rod is movably sleeved with the inner wall of the fixed mounting block.

The outer walls of each of the two clamping connecting columns are movably sleeved with the inner walls of the two clamping springs, and the two sides of each clamping spring are movably abutting against the inner sidewall of the movable groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this invention, by starting a rotating motor, the rotation of the motor drives a rotating rod to rotate via a coupling. The rotation of the rotating rod drives a grinding mounting shaft to rotate, which in turn drives a grinding side plate to rotate. The rotation of the grinding mounting shaft drives a grinding base plate to rotate. The rotation of the grinding side plate and the grinding base plate allows for simultaneous grinding of the top and sides of the zinc oxide resistor sheet, precisely eliminating production defects on the surface of the zinc oxide resistor sheet and avoiding over-grinding or under-grinding. This brings convenience to the production of zinc oxide resistor sheets.

[0013] In this invention, rotating the handle causes the crossbeam to move downwards, which in turn causes the motor to move downwards, which in turn causes the rotating rod to move downwards, which in turn causes the movable pressure rod to move downwards. The downward movement of the movable pressure rod, through the limiting mechanism of the inclined surface of the moving inclined plate and the sliding groove, causes the moving inclined plate to move linearly. The linear movement of the moving inclined plate causes the clamping connecting column to move linearly, which clamps the inner wall of the zinc oxide resistor sheet, facilitating subsequent grinding and bringing convenience to people using the zinc oxide resistor sheet grinding device.

[0029] The method of use and advantages of this utility model: The working process of this zinc oxide resistance sheet grinding device is as follows:

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, by starting the rotating motor 202, the rotation of the rotating motor 202 drives the rotating rod 203 to rotate via the coupling. The rotation of the rotating rod 203 drives the grinding mounting shaft 301 to rotate, which in turn drives the grinding side plate 302 to rotate, and the grinding mounting shaft 301 drives the grinding base plate 303 to rotate. The rotation of the grinding side plate 302 and the grinding base plate 303 allows for simultaneous grinding of the top and sides of the zinc oxide resistor sheet, precisely eliminating production defects on the surface of the zinc oxide resistor sheet and avoiding over-grinding or under-grinding. This brings convenience to the production of zinc oxide resistor sheets. (The text repeats itself here, so the translation will only include the first instance.) 06. Rotating handle 106 rotates the crossbeam 201 downwards, which in turn moves the rotating motor 202 downwards. The rotating motor 202 then moves the rotating rod 203 downwards, which in turn moves the movable pressure rod 401 downwards. The downward movement of the movable pressure rod 401, through the limiting action of the inclined surface of the movable inclined plate 501 and the sliding groove, causes the movable inclined plate 501 to move linearly. The linear movement of the movable inclined plate 501 causes the clamping connecting column 502 to move linearly. The linear movement of the clamping connecting column 502 can clamp the inner wall of the zinc oxide resistance sheet, facilitating grinding and bringing convenience to people using the zinc oxide resistance sheet grinding device.
