Abstract

The invention relates to a clamping device, and specially relates to a synchronous clamping device for a lever. The device comprises a base and pressing plate with clamping heads, wherein the device is further provided with a connecting arm, a supporting pin and a stud which vertically penetrates the base, the two pressing plates are oppositely arranged above the base, and supporting pins are arranged on the base far away from one ends of the pressing plates; the middle of the two pressing plates and the studs are sleeved in a hollow way, compression springs are arranged between the pressing plates and the base, the lower ends of the two studs are hinged through the connecting arm, the upper end of the stud is hinged with a pressing nut, and the middle of the connecting arm is hinged on the base. The two pressing plates of the clamping device are linked through the connecting arm, so as to guarantee synchronous clamping; and work-pieces can be successfully loosened from the pressing plates by the compression springs.

Description

Lever synchronous clamping device
Technical field
The present invention relates to a kind of clamping device, be specifically related to a kind of lever synchronous clamping device.
Background technology
In machine tooling, conventionally after need to using clamping device that workpiece is fixing, then carry out follow-up processing, so clamping device is widely used in workpiece manufacture field, and existing clamping device shortcoming has at present: 1., while having multiple pressing plate, pressing plate holding workpiece is asynchronous; 2. machine rear fixture and can not automatically unclamp workpiece.
Summary of the invention
The defect existing for above-mentioned prior art, the object of the present invention is to provide a kind of lever synchronous clamping device, this clamping device
For achieving the above object, technical scheme of the present invention is: lever synchronous clamping device, comprise pedestal and the pressing plate with clamping head, wherein, also be provided with link arm, fulcrum post and vertically run through the screw rod of pedestal, described pedestal top is provided with two pressing plates relatively, on the pedestal of two block pressur plates clamping head far away one end, is equipped with fulcrum post; Two block pressur plates middle parts all with described screw rod empty set, between pressing plate and pedestal, be provided with Compress Spring, it is hinged that described link arm is passed through in two screw rod lower ends, screw rod upper end is provided with binding nut, in the middle part of described link arm, is articulated with on pedestal.
While adopting technique scheme, workpiece to be clamped is positioned on the pedestal under two pressing plates, tighten the binding nut on a side guide, this side guide clamping head one end bottom, the supported pin of the other end supports, on the screw rod of this side, move simultaneously, the link arm hinged with this root screw rod rotates, and the screw rod hinged with opposite side moved down, thereby pull the pressing plate clamping head one end bottom being attached thereto, two clamping heads link by link arm, common holding workpiece.Unscrew after binding nut, Compress Spring sheathed on screw rod upwards promotes pressing plate, makes to put on pressing plate clamping head one end, and workpiece is unclamped.Two block pressur plates of the present invention link by link arm, guarantee synchronously clamping; Compress Spring can make pressing plate unclamp smoothly workpiece.
Further, described binding nut is provided with handle, and tightening and unscrew binding nut will be by special instrument, operate more loaded down with trivial details, and handle capable of being Quick fastening and unscrew binding nut.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of lever synchronous clamping device embodiment of the present invention.
The specific embodiment
As shown in Figure 1, a kind of lever synchronous clamping device, comprises pedestal 1 and the pressing plate 2 with clamping head, wherein, also be provided with link arm 4, fulcrum post 6 and vertically run through the screw rod 3 of pedestal 1, pedestal 1 top is relatively provided with on the pedestal 1 of two pressing plates, 2, two block pressur plate 2 clamping head far away one end and is equipped with fulcrum post 6; Two block pressur plate 2 middle parts all with screw rod 3 empty sets, between pressing plate 2 and pedestal 1, be provided with 7, two screw rod 3 lower ends of Compress Spring by link arm 4 hinged, screw rod 3 upper ends are provided with binding nut 5, wherein the binding nut 5 of a side is provided with handle, link arm 4 middle parts are articulated with on pedestal 1.
The concrete flow process of using:
As shown in Figure 1, workpiece to be clamped 8 is positioned on the pedestal 1 under two block pressur plates 2, pull the handle on right side binding nut 5, these side guide 2 clamping head one end bottoms, the supported pin 6 of the other end supports, on the screw rod 3 of this side, move simultaneously, the link arm 4 hinged with this root screw rod 3 rotates counterclockwise around the pin joint at middle part, the screw rod hinged with left side 3 moved down, thereby pull the pressing plate 2 clamping head one end bottoms that are attached thereto, the clamping head of two block pressur plates 2 links by link arm 4, common holding workpiece 8.The reverse handle of pulling on right side binding nut 5, Compress Spring 7 sheathed on screw rod 3 upwards promotes pressing plate 2, makes to put on pressing plate 2 clamping head one end, and workpiece 8 is unclamped.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of 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.
