Abstract
The invention discloses an eccentric clamping fixture, and achieves the effect that an arc edge of a workpiece can be fixed in the prior art. The eccentric clamping fixture is characterized by comprising a machine seat, a sliding block with a horizontal moving degree of freedom, a swing block hinged wit the machine seat, a connecting rod and a claw hinged with the machine seat, wherein a boss is arranged on the sliding block; a clamping claw pressed against two sides of the boss in the moving direction is arranged at the driving end of the swing block; the driven end of the swing block is hinged with the driving end of the connecting rod; the driven end of the connecting rod is hinged with the driving end of the clamping claw; and an eccentric tooth clamping part for clamping the arc edge of the workpiece is arranged at the driven end of the clamping claw. By the technical scheme, the eccentric clamping fixture has the characteristics that the sliding block is used as a force application device, so that the arc edge of the workpiece can be well fixed.
Description
Technical field
The present invention relates to the anchor clamps that use in a kind of machining.
Background technology
Jig is important process indispensable in machinery manufacturing industry equipment, as to punching press, riveted joint, the welding of workpiece, paste or solidify etc. in the process and usually need workpiece to keep correct position relationship.Clamping device can accurately locate workpiece by reference surface or the point of holding workpiece, can guarantee mechanical processing quality, enhances productivity, reduces production costs, reduce labor intensity.
In the process of reality, the shape and structure of workpiece is ever-changing, for heteroid workpiece designs corresponding with it anchor clamps, is mechanical field staff's long-range mission.And being fixedly clamped of workpiece arc-shaped side work in-process is exactly one.
Summary of the invention
The invention is intended to provide a kind of eccentric clamping fixture, to solve the fixation problem of workpiece arc-shaped side in the prior art.
Eccentric clamping fixture in this programme, it is characterized in that: comprise support, possess the free degree of moving horizontally slide block, with the hinged swinging block of support, connecting rod, the jaw hinged with support, slide block is provided with boss, the drive end of swinging block is provided with the claw that offsets with boss direction of motion both sides, the driven end of swinging block and the drive end of connecting rod are hinged, the driven end of connecting rod and the drive end of jaw are hinged, and the driven end of jaw is provided with the eccentric tooth clamping section for the clamping work pieces arc-shaped side.
The characteristics of technique scheme are: slide block can well be fixed the workpiece arc-shaped side as force application apparatus.
Further, described connecting rod is the expansion link that is provided with back-moving spring.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the schematic diagram of the embodiment of the invention.
The specific embodiment
As shown in Figure 1: the eccentric clamping fixture in this enforcement comprise support, the slide block 1 that is connected with the support horizontal slip, with the hinged swinging block 2 of support, connecting rod 3, the jaw 4 hinged with support, slide block is provided with boss 11, the drive end of swinging block is provided with the claw 21 that offsets with boss direction of motion both sides, the driven end of swinging block and the drive end of connecting rod are hinged, connecting rod is telescopic loop bar structure and is provided with back-moving spring, the driven end of connecting rod and the drive end of jaw are hinged, and the driven end of jaw is provided with the eccentric tooth clamping section 41 for the clamping work pieces arc-shaped side.
The working method of present embodiment is: by the move left and right of slide block, the boss on the slide block drives swinging block and rotates, and then the rotation of connecting rod drive jaw, to realize the clamping to workpiece.
Above-described only is embodiments of the invention, and the general knowledge such as known concrete structure and characteristic are not done too much description at this in the scheme.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.
