Abstract
The invention provides a connecting rod jacking clamp which is used for solving the fixed problem of the lower bottom surfaces of workpieces in the prior art. The connecting rod jacking clamp of the scheme is characterized by comprising a rack, a hydraulic cylinder which is used as a force application device, a connecting rod, a crank which is articulated with the rack, a rocker and a sliding block with a vertical motion freedom; and the piston rod of the hydraulic cylinder is articulated with the drive end of a connecting rod, the driven end of the connecting rod is articulated with the free end of the crank, moreover, the free end of the crank is articulated with the drive end of the crank, the driven end of the crank is articulated with the sliding block, and the upper surface of the sliding block is a compression surface. The technical scheme has the characteristic that the connecting rod jacking clamp can well clamp the lower bottom surfaces of the workpieces.
Description
Technical field
The present invention relates to the anchor clamps that use in a kind of machining.
Background technology
Jig is important process equipment indispensable in the machinery manufacturing industry, 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 the clamping of workpiece bottom surface work in-process is exactly one.
Summary of the invention
The invention is intended to provide a kind of connecting rod to hold out against anchor clamps, to solve the fixation problem of workpiece bottom surface in the prior art.
Connecting rod in this programme holds out against anchor clamps, it is characterized in that: comprise frame, the hydraulic cylinder as force application apparatus, connecting rod, with hinged crank, the rocking bar of frame, possess the slide block of the free degree of moving both vertically; The piston rod of hydraulic cylinder and the drive end of connecting rod are hinged, and the driven end of connecting rod and the free end of crank are hinged, and the drive end of the free end of crank and rocking bar is hinged simultaneously, and driven end and the slide block of rocking bar are hinged, and the upper surface of slide block is seal face.
The characteristics of technique scheme are: can well clamp the workpiece bottom surface.
Further, also comprise the auxiliary rocking bar hinged with support, the free end of auxiliary rocking bar and the drive end of connecting rod are hinged, and connecting rod is provided with the first block, and crank is provided with the second block, and slide block is in the limit for height position when the first block and the second block offset.Can limit the mobile height of slide block.
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 connecting rod in this enforcement holds out against anchor clamps and comprises frame, the hydraulic cylinder 2 as force application apparatus, connecting rod 3, crank 4, rocking bar 5, with the chute vertical slide block that be slidingly connected 6 hinged with frame; The piston rod of hydraulic cylinder and the drive end of connecting rod are hinged, and the driven end of connecting rod and the free end of crank are hinged, and the drive end of the free end of crank and rocking bar is hinged simultaneously, and driven end and the slide block of rocking bar are hinged, and the upper surface of slide block is seal face.Comprise in addition the auxiliary rocking bar 7 hinged with support, the free end of auxiliary rocking bar and the drive end of connecting rod are hinged, and connecting rod is provided with the first block 31, and crank is provided with the second block 41, and slide block is in the limit for height position when the first block and the second block offset.
The working method of present embodiment is: the piston rod of hydraulic cylinder is retracted, and drivening rod moves right, and drives free end rotation and the rising of crank, and the rising of rocking bar band movable slider realizes the clamping to the workpiece bottom surface.
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.
