Abstract

The invention belongs to the technical field of workpiece clamping devices, and particularly relates to a multi-station fixture which comprises a base. An eccentric cam is arranged on the base, a flange of the eccentric cam contacts with a connecting block placed on the base, the side face of the connecting block far away from the eccentric cam is in mortise-tenon connection with two pressing plates, a plurality of concave surfaces are arranged on the inner sides of the pressing plates, the concave surfaces of the two pressing plates are folded to form a workpiece groove containing a workpiece, two inclined surfaces are arranged on the outer sides of the pressing plates, and rollers are arranged at the inclined surfaces on the base. The multi-station fixture is simple in structure and applicable to batch jobs, a plurality of bars can be clamped, and the machining efficiency of a machine tool is improved.

Description

Multi-station clamp
Technical field
The invention belongs to Workpiece clamping device technical field.
Background technology
On the lathes such as existing milling machine, grinding machine, all can workpiece be fixed sectional fixture.Existing bar formula workpiece generally adopts universal fixturing, this universal fixturing comprises pilot sleeve, adjusts clamping plate and piece piece, adjust clamping plate and fixture block and form the clamping part for bar, the shortcoming of such scheme is: can only clamp a bar at every turn, the lathe that is not suitable for operation in enormous quantities, operating efficiency is low.
Summary of the invention
The invention is intended to provide a kind of fixture that clamps many bars, is applicable to operation lathe in enormous quantities.
Object of the present invention can reach by following measures: multi-station clamp, comprise base, base is provided with eccentric cam, and the flange of eccentric cam contacts with the coupling block being placed on base, and coupling block is connected with two pressing plate Tenons away from the side of eccentric cam; The inner side of described pressing plate is provided with multiple concave surfaces, and the workpiece groove of workpiece is held in the involutory rear formation of concave surface of two pressing plates; The outside of pressing plate is with two inclined-planes, and base is provided with roller at this place, inclined-plane.
Technique scheme difference with the prior art is: owing to being provided with the pressing plate that can form multiple workpiece grooves, increased the clamping station of bar workpiece, be applicable to the lathe of operation in enormous quantities; Pull the handle of eccentric cam, when the convex surface of eccentric cam and coupling block push against, coupling block promotes pressing plate and slides, and because the inclined-plane, outside of pressing plate is fixed with roller, two pressing plates are combined to form workpiece groove in sliding process more gradually, thereby by bar clamp.The present invention is simple in structure, can clamp many bars, is applicable to batch jobs, has improved machine tooling efficiency.
Further, coupling block is provided with protruding dovetail away from the side of eccentric cam, adopts dovetail joinery and its construction, makes the more firmly difficult drop-off of connection of pressing plate and coupling block.
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 multi-station clamp embodiment of the present invention.
The specific embodiment
As shown in Figure 1: multi-station clamp, comprises base 1, eccentric cam 2, pressing plate A, pressing plate B, coupling block 3 and four rolling 4.
It is upper that eccentric cam 2 is fixed on 1 of base, on eccentric cam 2, with handle, pulls handle and can make eccentric cam 2 rotate.On 1 of base, be shelved with coupling block 3, this coupling block 3 contacts with the flange of eccentric cam 2.Coupling block 3 is away from the side of eccentric cam 2 flanges with protruding dovetail, and the head end of pressing plate A and pressing plate B is with dovetail tongue-and-groove, and pressing plate A and pressing plate B Tenon are connected on coupling block 3.The side that pressing plate A is relative with pressing plate B is medial surface, all has the concave surface 4 of row's arc on the medial surface of pressing plate A and pressing plate B, pressing plate A and pressing plate B relative formation of concave surface 4 hold the workpiece groove of bar workpiece.The lateral surface of pressing plate A and pressing plate B is relative with the head and the tail position of concave surface 4 in a row respectively with inclined-plane 5,5, two, two inclined-planes, and base 1 is installed a roller 6 in the position on each inclined-plane 5.
The above is only the detailed description of preferred embodiment of the present invention, is not used for limiting the present invention, and the embodiment of all similar variations of doing according to creation spirit of the present invention, all should be contained among the present invention.
