Double-point compressing device

Abstract

The invention discloses a double-point compressing device which comprises a base, an X-direction moving platform mounted on the base and driven by a first power device, a Z-direction moving platform mounted on the X-direction moving platform and driven by a second power device, an X-direction telescopic arm mounted on the Z-direction moving platform, a first positioning and locking piece used for adjusting the retractable length of the X-direction telescopic arm and mounted on the Z-direction moving platform, two Theta-angle rotating arms and a second positioning and locking piece used for adjusting the rotary angles of the Theta-angle rotating arms, compressing elements mounted at the end parts of the two Theta-angle rotating arms, and pressure heads mounted at the bottoms of the elastic down-pressing pieces, wherein each compressing element comprises elastic down-pressing pieces fixed at the end parts of the Theta-angle rotating arms. According to the invention, compressing distance can be conveniently adjusted according to different sizes of the workpieces; double-point compressing is achieved, the distance between the two compressing elements can also be adjusted, and two compressing ways of compressing corners or middle point by workpieces with different sizes can be achieved.

Description

technical field [0001] The invention relates to a pressing device used in the process of workpiece processing and installation. Background technique [0002] The clamping device is an important part in the installation and processing of workpieces. The usual structure of the pressing device in the prior art is: it includes a guide arm driven by a power device that can move horizontally and vertically, and a pressing element is arranged at the end of the guide arm. The compression device with the above structure can only compress the workpiece at one point. If it is necessary to compress the workpiece at two points, for example, it is necessary to compress the workpiece diagonally or the middle of both sides of the workpiece, which cannot be realized by one device; And the pressing device of the above structure can only be pressed along a straight line direction, and cannot realize the pressing that deviates from the telescopic direction of the guide arm. In addition, in or...

Problems solved by technology

The compression device with the above structure can only compress the workpiece at one point. If it is necessary to compress the workpiece at two points, for example, it is necessary to compress the workpiece diagonally or the middle of both sides of the workpiece, which cannot be realized by one device; And the pressing device of the above structure can only be pressed along a straight line direction, and cannot realize the pressing that deviates from the telescopic direction of the guide arm.

In addition, in order to achieve fast operation, the length of the power device driving the guide arm to expand and contract is usually fixed in the pressing device in the prior art. After the workpiece is placed, the guide arm stretches out to compress the workpiece. After the workpiece is
