Adopt the upper and lower action of a cam mechanism control arm lock to the realization compresses tightly, loosens the action, and simple structure nevertheless moves reliable and stablely, and it is outstanding to compress tightly the effect.
Description
Technical field
The utility model relates to clamping tool, particularly relates to a kind of lever type clamping device, belongs to mechanical manufacturing field.
Background technology
When the major axis of machining crankshafts, minor axis and crank exterior arc surface, outer face, need the major axis or the minor axis that clamp bent axle, it is inaccurate to there is location in the clamping tool adopted the processing of same kind of parts outer round surface at present, thus causes machining tolerance large, the problem that precision is low.Good fixture can ensure crudy, and the top priority of jig ensures machining accuracy, particularly ensures that workpiece to be machined is machined surface and locating surface and surface to be machined positional precision each other.Boost productivity, reduce costs, the utility model can reduce the non-cutting times such as line, centering, and is easy to realize multistation processing.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of easy and simple to handle, lever type clamping device that accurate positioning, clamping effect are outstanding.
The technical scheme in the invention for solving the above technical problem is: lever type clamping device, comprise mount pad, connecting plate, jig arm, handle, briquetting and spring, mount pad is provided with V-type groove, the both sides of V-type groove are provided with installing hole, installing hole both ends open runs through, described jig arm penetrates this installing hole, described jig arm is at least two, the lower end of jig arm is fixedly connected with in common connecting plate, described briquetting through hole position and mount pad rotate to be installed, the axis of described briquetting in position, hole and mount pad rotate to be installed, the turning cylinder of briquetting is set for the eccentric, turning cylinder is fixedly connected with handle, spring one end support and connection plate, the spring other end supports mount pad.
The utility model also comprises thimble, and described thimble and connecting plate fixedly mount, and the corresponding briquetting other end in thimble one end props up spring.
Jig arm described in the utility model is L-shaped, and the pressure surface of L clevis arm is arc-shaped surface.
The utility model compared with prior art, has the following advantages and effect:
1, employing described in the utility model cam mechanism controls the knee-action of jig arm, thus realizes compressing, unclamping action, and structure is simple, but stable and reliable operation, compress superior.
2, the utility model adopts at least two L clevis arm workpiece pressings, compresses stress equalization, and the pressure surface of L clevis arm is that arc-shaped surface can the outer surface of comprehensive engagement shaft series products, avoids single-point unbalance stress, defective work piece.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
See Fig. 1, lever type clamping device described in the utility model, comprise mount pad 1, connecting plate 2, jig arm 3, handle 4, and spring 5, mount pad 1 is provided with V-type groove 11, V-type groove 11 is positions that workpiece G clamps, the both sides of V-type groove 11 are provided with installing hole 12, installing hole 12 is cylindrical holes that a both ends open runs through, described jig arm 3 penetrates this installing hole 12, described jig arm 3 is at least two, the lower end of jig arm 3 is fixedly connected with in common connecting plate 2, position, hole 13 is provided with in described mount pad 1, briquetting 6 through hole position 12 and mount pad 1 rotate to be installed, the axis of described briquetting 6 in position, hole and mount pad 1 rotate to be installed, the axis of position, hole refers to that direction perpendicular with paper is as shown in Figure 1 for axial, the turning cylinder of briquetting 6 is set for the eccentric, turning cylinder is fixedly connected with handle 4, spring 5 one end support and connection plate 2, spring 5 other end supports mount pad 1.
The utility model also comprises thimble 7, and described thimble 7 fixedly mounts with connecting plate 2, and the corresponding briquetting 6 in thimble 7 one end, the other end props up spring 5.
Jig arm 3 described in the utility model is L-shaped, and the pressure surface 31 of L clevis arm is arc-shaped surface.
Running: compress action, pull handle 4 downward, briquetting 6 rotates, and because briquetting 6 is eccentric structure, briquetting 6 outer surface can contact connecting plate 2 or thimble 7, drives jig arm 3 to move down, thus workpiece pressing G; Unclamp action, pull handle 4 upwards, briquetting 6 rotates, and because briquetting 6 is eccentric structure, briquetting 6 outer surface can depart from connecting plate 2 or thimble 7, and connecting plate 2 or thimble 7 are exerted pressure without the external world, under the effect of now spring 5 again, jig arm 3 is moved, thus unclamps workpiece G.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that the ordinary skill of this area just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
