Abstract
The invention discloses a clamp with adjustable clamping size. The problem that an existing clamp can clamp only a workpiece with fixed size, and using is limited is solved. The clamp comprises a base. A thread hole is formed in the middle of the base. Two sliding grooves are formed in the two opposite sides of the thread hole respectively. Each sliding groove is provided with a clamping table which can move along the corresponding sliding groove. A groove is formed in the upper portion of each clamping table. The two grooves are opposite and in a dovetail shape. Each clamping table is connected with a piston rod of a gas cylinder. A locating column is arranged in the thread hole. A flange is arranged at the top end of the locating column. The flange and the groove wall of each groove form a dovetail shape. By changing the distance between the groove walls of the grooves and the flange, the clamp can clamp shaft workpieces with different end face sizes.
Description
Technical field
The present invention relates to Machining Technology, be specifically related to a kind of adjustable fixture of size that clamps.
Background technology
fixture is widely used in the manufacture processing of workpiece, and considers the demand of the processing and manufacturing cost that as far as possible reduces workpiece, and General Requirements clamp structure is simple, convenient operation.At present, often there is following problem in the fixture of general shaft-like workpiece: a fixture can only clamp a kind of workpiece of radii fixus conventionally, all needs corresponding fixture like this for every kind of workpiece, has increased the use amount of fixture, increases cost.
Summary of the invention
The invention provides a kind of adjustable fixture of size that clamps, to solve existing a kind of fixture, can only clamp a kind of fixed dimension workpiece, use limited problem.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
The adjustable fixture of clamping size, comprise pedestal, pedestal middle part is provided with screwed hole, and the relative both sides of screwed hole are respectively equipped with two chutes, and on each chute, being equipped with can be along the grain-clamping table of runner movement, each grain-clamping table top all has groove, two grooves are dovetail shaped relatively, and each grain-clamping table is all connected with the piston rod of cylinder, in described screwed hole, are provided with locating dowel, the top of locating dowel is provided with flange, and the cell wall of flange and each groove all forms dovetail shaped.
This fixture beneficial effect: this fixture drives two grain-clamping table relative motions by cylinder piston rod, is the cell wall of swallow-tailed groove and the common clamping position workpiece of the flange on locating dowel top by each.This fixture grain-clamping table can be positioned at the diverse location of chute, so just can change the clamping size between grain-clamping table groove cell wall and flange, thereby this fixture can clamp the workpiece of different size, a kind of fixture is applicable to the clamping of various workpieces, the quantity that can reduce fixture, reduces costs.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention clamps the adjustable fixture embodiment of size.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
The adjustable fixture of clamping size as shown in Figure 1, comprise pedestal 1, pedestal 1 middle part is provided with screwed hole, the relative both sides of screwed hole are respectively equipped with two chutes 2, on each chute, being equipped with can be along the grain-clamping table 3 of runner movement, each grain-clamping table top all has groove, two grooves are dovetail shaped relatively, the bottom land of each groove is equipped with the locating piece 7 of two workpiece, to prevent that workpiece from overturning when the clamping position, each grain-clamping table is all connected with the piston rod 4 of cylinder, in screwed hole, be provided with locating dowel 5, the top of locating dowel 5 is provided with flange 6, flange 6 all forms dovetail shaped with the cell wall of each groove.
