Abstract

The invention discloses an ejector type pressing plate clamping device, and relates to a clamping device. The device comprises a base, a cam, a rotary handle, two pin shafts, a groove type sliding block and an ejecting cover, wherein the base is hinged with the cam, the cam is attached to the groove type sliding block and welded with the rotary handle, two groove arms of the groove type sliding block are respectively provided with a through hole, the two pin shafts penetrate through the through holes, one end of each pin shaft is connected with the base through a bolt, the other end of each pin shaft is connected with the ejecting cover through a bolt, and reset springs are arranged on two pin shaft sections between the groove type sliding block and the ejecting cover. The device overcomes the defects that the structure of an existing device is complex, clamping of workpieces is difficult and clamping is not firm, and improves machining efficiency.

Description

A kind of roof pressing type pressing plate clamping device
Technical field
The present invention relates to the clamping device technical field, particularly a kind of roof pressing type pressing plate clamping device.
Background technology
At present clamping device a large amount of use in machining, clamping device is that the workpiece of having good positioning is fixed on setting element in whole process reliably, and the occurrence positions mechanism that changes not.Do not allow to destroy the location of workpiece when clamping work pieces, and enough rigidity should be arranged, guarantee necessary clamping force, but should not damage the workpiece machined surface or make workpiece produce distortion, thereby guarantee machining accuracy.Because the outer surface of most of workpiece need to be processed, for the ease of the processing of lathe to workpiece, present clamping device complex structure, and operation is comparatively inconvenient, be difficult to workpiece is clamped, or clamping is firm not, makes the poor effect of its clamping, greatly reduce working (machining) efficiency, larger impact is played in production.
Summary of the invention
The invention provides a kind of simple in structurely, workpiece is easy to clamp, clamp firmly roof pressing type pressing plate clamping device.
in order to solve the problems of the technologies described above, the invention provides following technical scheme: a kind of roof pressing type pressing plate clamping device, comprise pedestal, cam, swing handle, two bearing pins, the fluted body slide block, top cover, described pedestal and cam are hinged, cam and fluted body slide block are fitted, cam and swing handle welding, respectively offer through hole on two groove arms of fluted body slide block, two bearing pins pass described through hole, two bearing pins end separately is bolted on pedestal, the other end is bolted on top cover, two bearing pin sections between fluted body slide block and top cover are provided with back-moving spring.
Beneficial effect: the present invention is driven the slip of fluted body slide block by rotating cam, workpiece is clamped, and is simple in structure, to firm workpiece clamping, and is provided with back-moving spring, can make this clamping device realize automatically reset function, improved operating efficiency.
Description of drawings
Fig. 1 is the schematic diagram of roof pressing type pressing plate clamping device structure embodiment of the present invention.
The specific embodiment
As shown in Fig. 1, roof pressing type pressing plate clamping device of the present invention, comprise pedestal 1, cam 2, swing handle 3, two bearing pins 4, fluted body slide block 5, top cover 6, described pedestal 1 is hinged with cam 2, cam 2 is fitted with fluted body slide block 5, cam 2 and swing handle 3 welding, respectively offer through hole on two groove arms of fluted body slide block 5, two bearing pins 4 pass described through hole, two bearing pins 4 end separately is bolted on pedestal 1, the other end is bolted on top cover 6, and 4 sections of two bearing pins between fluted body slide block 5 and top cover 6 are provided with back-moving spring 7.Workpiece 8 is put into fluted body slide block 5, cam 2 is fitted with the bottom of fluted body slide block 5, by swing handle 3 rotating cams 2, the surface of cam 2 is the circular arc of gradual change, and the clockwise rotation of cam 2 promotes fluted body slide block 5 and moves up, along with moving up of fluted body slide block 5, make also moving up of its workpiece 8, when the top of workpiece 8 heads in the groove of top cover 6, its workpiece 8 is clamped; If in the time of need to taking off workpiece 8, because the back-moving spring 7 on two bearing pins 4 in clamping process is compressed, when loosening swing handle 3, the reaction force that compressed back-moving spring produces promotes fluted body slide block 5 downwards, reverts to initial state.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
