Abstract
A connecting rod jacking fixture aims at solving the problem of fixation of the lower bottom face of a workpiece in the prior art. The connecting rod jacking fixture is characterized by comprising a rack, a hydraulic cylinder, a connecting rod, a crank, a rocking bar and a sliding block, wherein the hydraulic cylinder is used as a force application device, the crank and the rocking bar are hinged with the rack, and the sliding block has perpendicular movement freedom degree. A piston rod of the hydraulic cylinder is hinged with a driving end of the connecting rod, and a driven end of the connecting rod is hinged with a free end of the crank. The free end of the crank is hinged with a driving end of the rocking bar, and a driven end of the rocking bar is hinged with the sliding block. The upper surface of the sliding block is a compaction surface. The connecting rod jacking fixture has the advantages of being capable of well clamping the lower bottom face of the workpiece.
Description
Technical field
The utility model 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.
The utility model content
The utility model 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 first block, and crank is provided with second block, and slide block is in the limit for height position when first block and second block offset.Can limit the mobile height of slide block.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the schematic diagram of the utility model embodiment.
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 the auxiliary rocking bar 7 hinged with support in addition, the free end of auxiliary rocking bar and the drive end of connecting rod are hinged, and connecting rod is provided with first block 31, and crank is provided with second block 41, and slide block is in the limit for height position when first block and second block offset.
The working method of present embodiment is: the piston rod of hydraulic cylinder is withdrawn, and drivening rod moves right, and drives free end rotation and the rising of crank, and the rising of rocking bar drive slide block realizes the clamping to the workpiece bottom surface.
Above-described only is embodiment of the present utility model, and 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 the utility model structure, can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
