Abstract
The invention relates to a clamping device, in particular to a lever linkage clamping device. The device comprises a base and pressing plates with clamping heads, wherein the device is further provided with a connecting arm, a supporting pin, a pressing cam and studs which vertically penetrate the base, 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 one stud is hinged with the pressing cam, and the upper end of the other stud is provided with a fixed nut, and the middle of the connecting arm is hinged on the base. When a work-piece is clamped by the clamping device, the cam is self-locked at any position, and continuous application of force is not needed; and in addition, the two pressing plates are linked through the connecting arm, so that synchronous clamping can be guaranteed.
Description
Technical field
The present invention relates to a kind of clamping device, be specifically related to a kind of lever linkage clamp device.
Background technology
In machine tooling, after conventionally 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. during holding workpiece, force side need to continue the application of force; 2., while having a plurality of pressing plate, pressing plate holding workpiece is asynchronous.
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 linkage clamp device, and during this clamping device holding workpiece, cam is self-locking at an arbitrary position, without the lasting application of force; In addition, two block pressur plates link by link arm, guarantee synchronously clamping.
For achieving the above object, technical scheme of the present invention is: lever linkage clamp device, comprise pedestal and with the pressing plate of clamping head, wherein, also be provided with link arm, fulcrum post, compression cam 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, two screw rod lower ends are hinged by described link arm, and a screw rod upper end and described compression cam are hinged, another root screw rod upper end is provided with hold-down nut, and described link arm middle part is articulated with on pedestal.
While adopting technique scheme, workpiece to be clamped is positioned on the pedestal under two pressing plates, pull the handle that compresses cam, cam rotates, the component putting on pressing plate makes this side guide clamping head one end bottom, thereby holding workpiece, the supported pin of the other end supports, move simultaneously with on the hinged screw rod of compression cam, 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.Pull after the handle of pine compression cam, Compress Spring sheathed on screw rod upwards promotes pressing plate, makes to put on pressing plate clamping head one end, and workpiece is unclamped.Compression cam in the present invention, can self-locking when downward clamping platen, so need not continue the application of force; Two block pressur plates link by link arm, guarantee synchronously clamping.
Further, the screw rod between described compression cam and pedestal is provided with packing ring, and while rotating compression cam by handle, compression cam and the friction of pressing plate upper surface are very large, and packing ring can effectively be avoided the wearing and tearing of pressing plate upper surface, and changes packing ring conveniently.
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 linkage clamp device embodiment of the present invention.
The specific embodiment
As shown in Figure 1, a kind of lever linkage clamp device, comprise pedestal 1 and with the pressing plate 2 of clamping head, wherein, also be provided with link arm 4, fulcrum post 6, compress cam 5 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, 1 of pressing plate 2 and pedestal are provided with Compress Spring 7, two screw rod 3 lower ends are hinged by link arm 4, screw rod 3 upper ends are hinged with compression cam 5, the screw rod 3 compressing between cam 5 and pedestal 1 is provided with packing ring, another root screw rod 3 upper ends are provided with hold-down nut, and 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, upwards pull the handle 51 that compresses cam 5, compressing cam 5 rotates counterclockwise, compress cam 5 eccentric sides and go to pressing plate 2 one sides, the component putting on pressing plate 2 makes this side guide 2 clamping head one end bottoms, thereby holding workpiece 8, the supported pin 6 of the other end supports, on the screw rod 3 of this side, move simultaneously, rotate counterclockwise with the pin joint of the hinged link arm 4 of this root screw rod 3 around 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.Pull the handle 51 that compresses cam 5 downwards, 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.
