Description

Technical Field

[0001] This utility model relates to the technical field of filter cavity surface polishing device, and in particular to a filter cavity surface polishing device. Background Technology

[0002] With the continuous development of technology, filters are becoming more and more widely used. A filter is a filtering circuit composed of capacitors, inductors and resistors. During the manufacturing process, the filter housing usually has impurities such as burrs and flash. At this time, a filter cavity surface polishing device is often needed to polish the filter.

[0003] A filter polishing device disclosed in utility model patent application CN217019843U includes a cabinet. The lower end of the cabinet has multiple rollers. One side wall of the cabinet has a placement hole. A transparent fixing plate is hinged to the upper outer side of the cabinet. The lower end of the cabinet has a slag discharge port. Above the slag discharge port is a filter screen connected to the inner wall of the cabinet. A slider is slidably mounted on the upper side of the filter screen. A drive motor is connected to the upper side of the slider. A polishing disc is connected to the output end of the drive motor. Sliding rods penetrating the side walls of the cabinet are hinged to both sides of the slider. Sliding holes matching the sliding rods are provided on both sides of the cabinet. A handle is connected to the other end of each sliding rod. Sliding sleeves are slidably mounted on the outer sides of each sliding rod. A support rod is hinged to one side of each sliding sleeve. The advantages of this invention compared to the prior art are: the waste generated during grinding can be easily collected, and the clamp can firmly fix filters of different sizes that need to be ground. However, when using this device, the filters need to be fixedly installed before grinding. When multiple filters need to be ground, the grinding disc cannot grind the filters during the disassembly and installation process, resulting in relatively low processing efficiency. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a filter cavity surface grinding device, which can solve the technical problem that when using the device, the filter needs to be fixedly installed before grinding. When multiple filters need to be ground, the grinding disc cannot grind the filters during the disassembly and installation process, resulting in relatively low processing efficiency.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a filter cavity surface polishing device, including a worktable, a bracket fixedly connected to the upper end of the worktable, a motor provided at the lower end of the worktable, the output end of the motor passing through the worktable and fixedly connected to a fixed block, and a limit groove provided on the side of the fixed block, a first electric telescopic rod provided at the upper end of the worktable, a limit block fixedly connected to the output end of the first electric telescopic rod, the limit block cooperating with the limit groove, a disc fixedly connected to the upper end of the fixed block, a pair of placement boxes fixedly connected to the upper end of the disc, and a fixing component provided on the placement box, a second electric telescopic rod provided on the bracket, a driving device fixedly connected to the output end of the second electric telescopic rod, and a polishing disc fixedly connected to the output end of the driving device.

[0006] As a preferred technical solution of this utility model, the fixing component is as follows: a crossbar is provided through one side of the placement box, a handle is fixedly connected to one end of the crossbar, a spring is fixedly connected to one side of the placement box, and a clamping plate is fixedly connected to the other end of the crossbar, and an anti-slip buffer pad is provided on one side of the clamping plate.

[0007] As a preferred embodiment of this utility model, the anti-slip buffer pad is made of rubber.

[0008] As a preferred embodiment of this utility model, an industrial vacuum cleaner is provided at the upper end of the bracket, and suction pipes are provided on both sides of the industrial vacuum cleaner, with a cover connected to one end of each suction pipe.

[0009] As a preferred embodiment of this utility model, a control panel is provided at the upper end of the workbench.

[0010] As a preferred embodiment of this utility model, the workbench is fixedly connected to the lower corner of each workbench with a support leg.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] First, start the drive unit, which rotates the grinding disc. Then, start the second electric telescopic rod, which moves the drive unit and the grinding disc downwards until the grinding disc contacts the filter surface and begins grinding. During grinding, the filter to be ground can be fixedly installed into another placement box. After grinding, start the second electric telescopic rod, which indirectly moves the grinding disc upwards a short distance. Simultaneously, start the first electric telescopic rod, which moves the limiting block away from the limiting groove on the fixed block. At the same time, start the motor, which rotates the fixed block, the disc, and the filter in the placement box 180 degrees simultaneously, allowing the filter to be ground to move upwards. The filter to be ground is moved below the grinding disc, and the first electric telescopic rod is activated again. The output end of the first electric telescopic rod drives the limiting block to insert into the limiting groove and limit and fix the fixing block and the disc, thus facilitating the grinding process. At this time, the second electric telescopic rod is activated again. The second electric telescopic rod drives the grinding disc to move downward and grind the filter to be ground. At the same time, the ground filter in the box can be disassembled and installed. With this device, during the grinding process of the filter to be ground, the ground filter can be disassembled and another filter to be ground can be fixedly installed, thereby improving processing efficiency.

[0018] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.

[0019] Example

[0020] Please refer to Figures 1-3 As shown, this utility model provides a filter cavity surface polishing device. The anti-slip buffer pad 17 is made of rubber, which can better fix the filter. An industrial vacuum cleaner 18 is set at the upper end of the bracket 2. Since the industrial vacuum cleaner 18 is an existing mature technology, it is not described in detail. Both sides of the industrial vacuum cleaner 18 are provided with suction pipes 19, and one end of the suction pipe 19 is connected to a cover 20. A control panel 21 is set at the upper end of the workbench 1. Support legs 22 are fixedly connected to the lower corner of the workbench 1. The control panel 21, motor 3, first electric telescopic rod 6, second electric telescopic rod 10 and industrial vacuum cleaner 18 on this device are all electrically connected to an external power source and are all controlled by the control panel 21, thereby ensuring that the device can be used normally.

[0021] During use, the industrial vacuum cleaner 18 can be started via the control panel 21. Under the action of the industrial vacuum cleaner 18, the debris generated during the filter grinding process enters the industrial vacuum cleaner 18 through the cover 20 and the suction pipe 19, thereby avoiding the debris from flying and affecting the workers during the grinding process.

[0022] As a further implementation of this embodiment, such as Figures 1-4As shown, a bracket 2 is fixedly connected to the upper end of the workbench 1, and a motor 3 is installed at the lower end of the workbench 1. The motor 3 in this device is a type of stepper motor 3, which can effectively control the rotation angle. The output end of the motor 3 passes through the workbench 1 and is fixedly connected to the fixed block 4. Limiting grooves 5 are opened on the sides of the fixed block 4. A first electric telescopic rod 6 is installed at the upper end of the workbench 1. A limiting block 7 is fixedly connected to the output end of the first electric telescopic rod 6. The limiting block 7 cooperates with the limiting groove 5. A disc 8 is fixedly connected to the upper end of the fixed block 4. The upper end of the disc 8 is fixedly connected to... A pair of placement boxes 9 are provided, and a fixing component is provided on the placement box 9. A second electric telescopic rod 10 is provided on the bracket 2. A drive device 11 is fixedly connected to the output end of the second electric telescopic rod 10. A grinding disc 12 is fixedly connected to the output end of the drive device 11. The fixing component is as follows: a crossbar 13 is provided on one side of the placement box 9. A handle 14 is fixedly connected to one end of the crossbar 13. A spring 15 is fixedly connected to the handle 14 and one side of the placement box 9. A clamping plate 16 is fixedly connected to the other end of the crossbar 13. An anti-slip buffer pad 17 is provided on one side of the clamping plate 16.

[0023] In use, first start the drive unit 11, which drives the grinding disc 12 to rotate. Then start the second electric telescopic rod 10, which drives the drive unit 11 and the grinding disc 12 to move downwards until the grinding disc 12 contacts the filter surface and performs grinding. During the grinding process, the filter to be ground can be fixedly installed into another placement box 9. After grinding is completed, start the second electric telescopic rod 10, which indirectly drives the grinding disc 12 to move upwards a certain distance. At the same time, start the first electric telescopic rod 6 directly, which drives the limiting block 7 to move away from the limiting groove 5 on the fixing block 4. Simultaneously, start the motor 3, which drives the fixing block 4, the disc 8, and the filter in the placement box 9. Simultaneously rotate 180 degrees to move the filter to be polished below the polishing disc 12, and then activate the first electric telescopic rod 6. The output end of the first electric telescopic rod 6 drives the limiting block 7 to insert into the limiting groove 5 and limit and fix the fixing block 4 and the disc 8, thereby facilitating the polishing process. At this time, activate the second electric telescopic rod 10 again. The second electric telescopic rod 10 drives the polishing disc 12 to move downward and polish the filter to be polished. At the same time, the polished filter in the placement box 9 can be disassembled and installed. With this device, during the polishing process of the filter to be polished, the polished filter can be disassembled and another filter to be polished can be fixedly installed, thereby improving processing efficiency.

[0024] Specific working principle: In use, firstly, the drive device 11 is started, which drives the grinding disc 12 to rotate. Then, the second electric telescopic rod 10 is started, which drives the drive device 11 and the grinding disc 12 to move downwards until the grinding disc 12 contacts the filter surface and performs grinding. During the grinding process, the filter to be ground can be fixedly installed into another placement box 9. (To fix the filter to be ground, simply pull the handle 14 to one side, which moves the handle 14, the crossbar 13, and the clamping plate 16, and places the filter to be ground into the placement box 9. Then, stop pulling the handle 14, and under the elastic force of the spring 15, the clamping plate 16 can be moved to the other side to clamp and fix the filter to be ground.) After grinding is completed, the second electric telescopic rod 10 is started, which indirectly drives the grinding disc 12 to move upwards a certain distance. At the same time, the first electric telescopic rod 6 is directly started, which moves the first electric telescopic rod 10 upwards. The telescopic rod 6 drives the limiting block 7 away from the limiting groove 5 on the fixed block 4. At the same time, the motor 3 is started, which drives the fixed block 4, the disc 8, and the filter in the placement box 9 to rotate 180 degrees simultaneously, so that the filter to be polished moves below the polishing disc 12. Then, the first electric telescopic rod 6 is started again, so that the output end of the first electric telescopic rod 6 drives the limiting block 7 to insert into the limiting groove 5 and limit and fix the fixed block 4 and the disc 8, thereby facilitating the polishing process. At this time, the second electric telescopic rod 10 is started again, which drives the polishing disc 12 to move downward and polish the filter to be polished. At the same time, the polished filter in the placement box 9 can be disassembled and another filter to be polished can be installed. With this device, during the polishing process of the filter to be polished, the polished filter can be disassembled and another filter to be polished can be fixedly installed, thereby improving the processing efficiency of the device.
