TW487612B - Fixture capable of clamping multiple workpieces at the same time - Google Patents

Abstract

This invention is related to a fixture capable of clamping multiple workpieces at the same time, comprising: a shaft, at least one expansion tube, and at least one nut. The expansion tube and a retaining tube are engaged over the shaft sequentially. An inner surface of the expansion tube and an outer surface of the shaft form a compartment. After the multiple workpieces are engaged over the expansion tube, the nut is threaded to the shaft for forcing the workpieces to align with one another. Fluid is injected into the compartment to apply pressure continuously, causing expansion of the expansion tube so as to be tightly fitted with the workpieces. The multiple workpieces are affixed to the shaft. The length of the shaft may be adjusted based on the needs, such that this invention is capable of clamping multiple workpieces at the same time.

， Expansion tube between 2 〇 0 without leaking, continue to pressurize the fluid. Because the% expansion tube 200 has a certain elasticity, it will increase in size in the radial direction after compression, resulting in 600 per workpiece. The contact between the inner surface and the outer surface of the expansion tube 2000 is in a tight fit state, so the workpiece 600 is fixed on the shaft 100, and the expansion tube 200 can expand in a radial direction from about The pressure of the fluid injected into the chamber 1 2 3 is preferably from 0. 5 mm to 0 2 mm, preferably from about 500 kg / cm 2 to 250 kg / cm 2. Please refer to the third and fourth figures again. When the workpiece 600 is to be processed, first seal the oil filling port 13 2 to keep the fluid in the chamber 1 2 3 and maintain a certain pressure. The lever 100 is removed from the chuck 5 10 of the machine 500, and the shaft 100 is mounted on a rotating shaft of a processing machine (not shown in the figure) together with a workpiece 600 fixed thereon. And for each piece of 600 machining, the present invention can process most of the workpieces at the same time. To release the workpiece 600 from the shaft 100, it is only necessary to open the oil injection port 1 3 2 to drain the fluid. The radial dimension of the expansion tube 2000 will return to the size before the pressurization, so the workpiece 600 can be released. Although the present invention has been disclosed with preferred embodiments as described, it is not intended to limit the present invention. 'Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of the appended patent application.
