Description

Quick clamping device for workpiece processing

technical field

The invention belongs to the technological equipment technology of mechanical processing and welding, and mainly relates to a fast pressing device for workpiece processing.

Background technique

Before the workpiece is machined and welded, the workpiece must first be placed in the correct position, that is, the workpiece positioning. In order to maintain the correct position of the workpiece, it is necessary to compress the workpiece. The compaction of the workpiece is an important guarantee to keep the correct position of the workpiece unchanged, and it is very important for the processing and welding process of the workpiece. Quickly pressing the workpiece can reduce the auxiliary time of workpiece processing and welding, improve production efficiency, and reduce the cost of workpiece processing.

Detailed ways

The present invention is described in conjunction with the embodiment that accompanying drawing provides:

As shown in Figures 1 and 2, a fast pressing device for workpiece processing mainly includes a handle 8, a base 7 and a carrier of the pressing mechanism; Hinge connection constitutes a hinged four-bar mechanism; wherein, the carriers of the pressing mechanism are the left and right chuck bodies 3, 4, and the front end is provided with a pressing body that moves up and down with the handle to press the workpiece, and the pressing mechanism The compression body at the front end of the carrier is a combined structure of a nut 2, a compression screw 1 and a pressure block 5, wherein the nut 2 is screwed with the compression screw 1 and is fixedly connected with the carrier of the compression mechanism, and the pressure block 5 is located in the compression The lower end of the screw 1; the specific connection structure of the pressing block 5 and the pressing screw 1 can be: the pressing block (5) is a nut structure, and the pressing screw has an optical axis section, and the lower end of the pressing screw is screwed into the pressing block 5 by threads Inside, make the pressure block 5 and the compression screw 1 form a floating connection. The briquetting block 5 at the lower end of the compression screw 1 exerts pressure directly on the workpiece 9; the rear ends of the left and right chuck bodies 3 and 4 all have upper and lower holes through which the left chuck body 3 and the right chuck body 4 pass. The coaxial hole in the lower part and the corresponding hole on the base 7 are hingedly connected with the base 7, so that the left chuck body 3 and the right chuck body 4 can rotate around the base 7, and the left chuck body 3 and the right chuck body 4 pass through the upper The coaxial hole and the corresponding hole on the handle are hingedly connected with the handle 8 so that they can rotate relative to each other; a connecting piece 6 is provided with two hinged holes, one end of which is hinged with the handle 8 through the hinged hole, and the other end Hinged with the base 7 through the hinge hole, so that the handle 8 is hinged with the base 7 through the connecting piece 6, so that the handle 8 can rotate relative to the base 7; when the handle 8 is pressed down, it rotates relative to the base 7 through the connecting piece 6, and drives the left clip The head body 3 and the right chuck body 4 swing downward relative to the base 7, and then drive the compression screw 1 to move downward, and the lower end pressure block 5 compresses the workpiece 9 to realize the fast compression function.

The self-locking principle of the pressing device of the present invention: in the pressing device, the left and right chuck bodies 3, 4, the base 7, the connecting piece 6 and the handle 8 are all connected with each other by rivets to form a hinge four-bar mechanism. By determining the size between two adjacent holes of the four workpieces, it constitutes a double rocker mechanism in the hinge four-bar mechanism. When the handle 8 is pressed down, the left and right chuck bodies 3 and 4 and the connecting piece 6 are driven to swing to the left around the left and right hole axes of the base respectively. When on a straight line (that is, the axis of the two holes of the handle 8 and the axis of the right hole of the base 7 are on the same straight line), the double rocker mechanism is in a self-locking state (that is, the dead point position), and the pressing mechanism is in a self-locking state at this time, and the workpiece 9 After the workpiece 9 is processed, lift the handle 8 upwards, drive the left and right chuck bodies 3, 4 and the connecting piece 6 to swing to the right around the two left and right holes of the base 7 respectively, and drive the compression screw 1 upwards, Loosen workpiece9. When the fixture is installed, adjust the height of the compression screw 1 so that the mechanism is in a self-locking state (i.e. dead point position) when the workpiece 9 is compressed.
