Description

Technical Field

[0001] This utility model relates to the field of PPS sheet processing technology, specifically to a tooling for removing burrs from sheets. Background Technology

[0002] The main material of the needle fixture for probes larger than 70um is PPS engineering plastic. Currently, the only imported PPS available is 6.0mm. However, the actual fixtures used require various sizes such as 0.8, 10, 1.2, 1.5, and 3.0mm. Currently, the industry uses imported PPS from Japan. Imported PPS from Japan has high rigidity and fewer burrs when drilling, but it is more expensive. Generally, the cost of a 250+250*6mm sheet is around 800 yuan.

[0003] Domestically produced PPS has poor rigidity and produces many burrs during drilling, but it is inexpensive, costing only 200 yuan for a 250*250*6mm PPS. Therefore, the main problem to be solved with existing domestically produced PPS is the difficulty in cleaning drilling burrs. Due to the small hole diameter, traditional grinding and polishing processes are very slow and require excessively high precision. Therefore, plasma technology is now widely used for deburring. However, in actual operation, the board needs to be deburred on both sides, requiring a flipping process. Furthermore, for areas where deburring is not complete in the first pass, a second deburring is needed after microscopic observation, requiring multiple passes into and out of the plasma cleaning machine, which is very cumbersome. Therefore, a board burr removal fixture is specifically provided. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tooling for removing burrs from sheet metal, which solves the problems mentioned in the background section.

[0023] The technical effects and advantages of this utility model are as follows:

[0024] This sheet metal deburring fixture works by inserting the workpiece into a workpiece fixture and then moving it via a three-axis drive to position it directly opposite the plasma generator at a suitable height. The plasma generator ionizes the internal argon gas to form a plasma beam that irradiates the workpiece surface, achieving plasma deburring. After one irradiation, the surface is directly observed under a microscope. The three-axis drive then moves the workpiece closer to the plasma generator for secondary deburring. Finally, a flipping drive rotates the workpiece for reverse deburring. This allows for double-sided deburring in one pass inside the plasma chamber without the need for removal, making it more convenient and faster. Furthermore, the plasma chamber does not require multiple vacuuming processes, reducing costs and complexity. Attached Figure Description

At this time, an external vacuum pump is connected through the vacuum pump connector 5 to evacuate the inside of the plasma chamber 1, and then argon gas is introduced through the gas supply connector 4. The plasma generator 2 ionizes the internal argon gas to form a plasma beam that irradiates the surface of the workpiece, thereby achieving the plasma deburring effect. After one irradiation, the workpiece is directly observed through the microscope 3. Then, the three-axis drive 6 is adjusted according to the area that is not cleaned, so that the target area is closer to the plasma generator 2 for secondary deburring. Then, the workpiece is flipped by the flip drive 73 for reverse deburring. In this way, double-sided deburring is completed in one go inside the plasma chamber 1 without the need to remove it in the middle, which is more convenient and faster. The plasma chamber 1 also does not need to be evacuated multiple times, reducing costs and difficulty.
