Description

TECHNICAL FIELD

[0001] The application relates to the polishing technical field, in particular to a polishing device for the outer bottom arc surface of a packaging tube shell. BACKGROUND

[0002] In the field of electronic packaging, ceramic packaging tube shells are widely used in scenes with high requirements for environmental adaptability and signal stability due to the comprehensive advantages of high temperature resistance, high insulation and excellent mechanical strength, and become the core packaging carrier of high-reliability electronic devices. In the processing flow of the ceramic packaging tube shell, in order to ensure that the smoothness of the outer surface of the tube shell meets the standard (avoiding that surface defects affect the packaging sealing performance, heat dissipation performance and subsequent assembly precision), the outer surface of the tube shell needs to be finely polished by a special polishing device to meet the high-precision process requirements of electronic device packaging.

[0003] In the operation of the existing packaging tube shell polishing device, a sand belt is usually used to polish the tube shell. However, the sand belt is a high-frequency loss part and needs to be replaced regularly to ensure the polishing accuracy. In the traditional device, the sand belt is usually tensioned on the roller way. When replacing the sand belt, the staff needs to manually adjust the roller way spacing to control the tightness of the sand belt. The whole replacement process is complicated and seriously affects the overall operation efficiency of the polishing device. SUMMARY

[0004] The application relates to a polishing device for the outer bottom arc surface of a packaging tube shell, which can automatically reduce the spacing between two polishing shafts when the polishing sand belt is in a non-use state, so that the polishing sand belt is no longer tensioned and positioned, facilitating the disassembly and replacement of the polishing sand belt. Meanwhile, the spacing between the two polishing shafts can be increased before the polishing sand belt is lowered into a use state, so that the polishing sand belt is tensioned before use, facilitating the normal polishing work of the polishing sand belt. In this way, the replacement of the polishing sand belt is not only convenient, but also ensures the use stability of the polishing sand belt. In the device, the tension state of the polishing sand belt is associated with the lifting state of the slide rail, and the clamping mechanism composed of the clamping piece A and the clamping piece B is also associated with the lifting state of the slide rail. The slide rail is lowered to clamp the workpiece by the clamping mechanism, and vice versa. When the slide rail is lifted into a non-use state, the fixing column is withdrawn from the fixing hole, facilitating the disassembly and replacement of the motor by the staff.

[0005] The application discloses a polishing device for the outer bottom arc surface of an encapsulating tube shell.

[0006] Further, the base plate is in T-shaped structure; the top end of the guide groove is in inclined structure; the rear top end of the guide column is fixedly installed with a push cylinder.

[0007] Further, the top front end of the base plate is fixedly installed with a clamping seat A; the clamping seat A is rotatably installed with a clamping piece A; the top center of the base plate is fixedly installed with a clamping seat B; the clamping seat B is slidably installed with a sliding block; the sliding block and the clamping seat B are jointly embedded with a spring.

[0008] Further, the rear end of the sliding block is in inclined structure; the front end of the sliding block is fixedly installed with a connecting head; the outer wall of the connecting head is threadedly connected with a positioning bolt; the front end of the connecting head is rotatably installed with a clamping piece B.

[0009] Further, the clamping piece B and the clamping piece A are on the same horizontal line; the inner end of the positioning bolt abuts against the clamping piece B; the top of the base plate is fixedly installed with a lifting seat.

[0010] Further, the lifting seat is located between the clamping seat A and the clamping seat B; the top of the lifting seat is slidably installed with a lifting plate; the rear side of the sliding rail is fixedly connected with the output shaft of the push cylinder.

[0011] Further, the lifting plate and the lifting seat are jointly embedded with a spring; the top of the lifting plate is placed with a workpiece; the workpiece is located between the clamping piece A and the clamping piece B.

[0012] Further, the fixed column and the tensioning sliding block are in sliding cooperation; the two tensioning sliding blocks are embedded with a spring; the rear end of the sliding column is slidably installed in the inner part of the guide groove.

[0013] Further, the inner part of the installation groove on the right side is slidably installed with a module base; the right side of the module base is provided with a fixed hole; the left side of the module base is fixedly installed with a motor.

[0014] Further, the rear end of the right polishing shaft is connected with the output shaft of the motor through a spline; a pushing block is fixedly installed at the middle position of the bottom of the slide rail; and the bottom end of the pushing block is in an inclined structure.

[0015] The packaging tube outer bottom camber polishing device has the following advantages: (1) The device has an automatic sand belt tightness adjusting function. When the polishing sand belt is in a non-use state with the structure rising, the distance between the two polishing shafts will automatically decrease, so that the polishing sand belt is released from tension positioning, and the staff does not need to manually adjust the roller, and the sand belt can be quickly disassembled and replaced. Before the polishing sand belt enters the use state with the structure descending, the distance between the two polishing shafts will automatically increase, so that the polishing sand belt is pre-tensioned, ensuring that the sand belt is stable and does not slip during subsequent polishing operation. The sand belt replacement process is simplified, and the stability of the polishing process is ensured.

[0016] (2) The device realizes multi-structure linkage control through the lifting state of the slide rail. Not only the tightness of the polishing sand belt is associated with the lifting of the slide rail, but also the working state of the workpiece clamping mechanism composed of the clamping piece A and the clamping piece B is synchronized with the lifting of the slide rail. When the slide rail descends, the clamping mechanism automatically clamps and positions the workpiece, ensuring that the workpiece does not deviate during polishing. When the slide rail rises into a non-use state, the clamping mechanism synchronously releases the clamping of the workpiece, facilitating the taking and placing of the workpiece. At the same time, after the slide rail rises, the fixed column automatically comes out of the fixing hole, so that the motor is released from the fixing limitation, and the staff can easily disassemble, maintain or replace the motor, further improving the overall operation and maintenance efficiency of the device.
