Self-adjustment compressing device

Abstract

The invention discloses a self-adjustment compressing device which comprises a hex nut, a fixture and a stud which is fixed on the fixture. Two sides of a protruding portion of the middle of the stud are cut, and the protruding portion is processed into a flat shape. An eccentric pressing plate is arranged on the stud, a spacer is arranged on the lower end surface of the eccentric pressing plate which is connected with the spacer through a strong spring, and a tapered washer is arranged on the upper end surface of the eccentric pressing plate. A spherical washer is arranged between the hex nut and the tapered washer. According to the self-adjustment compressing device, the operation height of the device can be adjusted by increasing or decreasing the number of the spacers, so that the device has generalities in a certain range; and workpieces can be detached by lifting the eccentric pressing plate under the action of the strong spring after the process, so that the device is convenient and rapid.

Description

technical field [0001] The invention relates to a self-adjusting pressing device, in particular to a self-adjusting pressing device capable of fixing irregular workpieces. Background technique [0002] During the use of tooling fixtures, it is usually necessary to equip some auxiliary tools for auxiliary clamping, such as pressure plates and pads for fixing tooling fixtures, to protect workpieces; in addition, there are some protective accessories, such as preventing workpieces from Flying device during rotation. [0003] At present, pressure plates and bolts are usually used as auxiliary tools for fixtures. After long-term observation and research, the applicant found that the use of pressure plates and bolts for auxiliary fixation or compression has certain limitations. For occasions that need to play an auxiliary pressing role, in order to obtain the best pressing effect, it is usually necessary to repeatedly adjust the height of the bolts so that the pressing plate is ...

AI Technical Summary

Problems solved by technology

For occasions that need to play an auxiliary pressing role, in order to obtain the best pressing effect, it is usually necessary to repeatedly adjust the height of the bolts so that the pressing plate is pressed horizontally on the workpiece, so that the center of gravity of the pressing can be evenly distributed, and the work efficiency is low; while For occasions that require protection, especially in mass production, in order to ensure the continuity of production, it is usually required that the device has the ability to quickly tighten and tighten, and the pressure plate and bolts are used for auxiliary compression. Every time the workpiece is replaced, it needs to be reinstalled Disassembly and compression further reduce work efficiency
