Description
Technical field
The utility model relates to a kind of adjustable pneumatic fraise jig.
Background technology
In mechanical processing process, workpiece can be subject to the effect of cutting force, centrifugal force, inertia force and gravity etc., in order to ensure under these External Force Actings, workpiece still can by setting element determination Working position in fixture, and be unlikely to occur vibration and displacement, therefore, all must arrange certain clamping device in clamp structure workpiece is reliably clipped.
Traditional pneumatic fraise jig, because the moving range of top pressing board is smaller, and workpiece height gap to be processed is comparatively large, so, when processing the product of differing heights, needing to change different fixtures, have impact on operating efficiency.
Utility model content
For the problems referred to above, the utility model provides a kind of adjustable pneumatic fraise jig, conveniently can clamp the workpiece of differing heights, and avoiding affects working (machining) efficiency because changing fixture, increases the scope of application of fixture.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of adjustable pneumatic fraise jig, it is characterized in that, comprise the distributing valve be arranged on clamp body, described distributing valve is by connecting pipe and cylinders, piston is provided with in described cylinder, the end of piston rod is connected with simple chain lever by roller, the other end of described lever is connected with the top pressing board for workpiece pressing surface, back-up block is provided with between the bottom of described roller and clamp body, be provided with gripper shoe between described workpiece and clamp body, be provided with several blind holes bottom described gripper shoe and be fixed on clamp body by several screws.
Preferably, described clamp body is provided with positioning key, described clamp body is connected with the T-slot of milling machine table by positioning key.
Preferably, clamping section is provided with inside described top pressing board.Wherein, clamping section outer surface is provided with abrasive rubber layer.Described clamping section is the hemispherical of projection.
Wherein, the upper surface of workpiece is step surface, add man-hour, fixture is coordinated with milling machine table T-slot by positioning key and is arranged on lathe, workpiece for positioning datum, utilizes the pneumatic shuttle of single effect, when pistons work with bottom surface and side, by simple chain lever pushing top pressing board clamping work pieces, carry out follow-up processing.When processing the workpiece of differing heights, only needing the gripper shoe of replacing differing heights and tightening screw, convenient and quick, add the scope of application of fixture.
The beneficial effects of the utility model are: the workpiece that conveniently can clamp differing heights, and avoiding affects working (machining) efficiency because changing fixture, use relatively more flexible, add the scope of application of fixture.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of adjustable pneumatic fraise jig of the utility model;
The mark implication of accompanying drawing is as follows:
1: workpiece; 2: gripper shoe; 3: distributing valve; 4: connecting pipe; 5: cylinder; 6: piston; 7: piston rod; 8: roller; 9: lever; 10: back-up block; 11: top pressing board; 12: positioning key; 13: blind hole; 14: screw.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, technical solutions of the utility model are described in further detail, to make those skilled in the art better can understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.
A kind of adjustable pneumatic fraise jig, as shown in Figure 1, comprise the distributing valve 3 be arranged on clamp body, described distributing valve 3 is connected with cylinder 5 by connecting pipe 4, cylinder 5 is power set of fixture, be provided with piston 6 in described cylinder 5, the end of piston rod 7 is connected with simple chain lever 9 by roller 8, and the other end of described lever 9 is connected with the top pressing board 11 for workpiece pressing 1 surface.Lever 9 changes over vertical clamping force the active force of level.
Preferably, be provided with clamping section inside described top pressing board 11, such as, described clamping section is the hemispherical of projection, preferably clamping section outer surface is provided with abrasive rubber layer.Abrasive rubber is Heveatex from after gum gathers, through filtration, purification, solidify, dewater, wash, granulation, drying, classification and packaging, the solid block natural rubber obtained, material is good and durable.
Be provided with back-up block 10 between the bottom of described roller 8 and clamp body, wherein, be provided with gripper shoe 2 between described workpiece 1 and clamp body, gripper shoe 2, as buffer board, after avoiding long-time use, causes wearing and tearing uneven to clamp body, affects clamping effect.Be provided with several blind holes 13 bottom gripper shoe 2 and be fixed on clamp body by several screws 14, in Fig. 1, only illustrating 1.
Blind hole 13 inwall is provided with screw thread, and screw 14 runs through the clamp body fixed support plate 2 bottom it.When processing the workpiece 1 of differing heights, only need fix the work of getting final product by the gripper shoe 2 changing differing heights, and whole fixture need not be changed, greatly improve the scope of application of working (machining) efficiency and fixture, preferably, described gripper shoe 2 bottom even is provided with three blind holes 13, and accordingly, the quantity of screw 14 is also three.
In order to increase the use flexibility of fixture, preferably, described clamp body is provided with positioning key 12, described clamp body is connected with the T-slot of milling machine table by positioning key 12.Milling machine is facilitated to change fixture to process different products.
Wherein, the upper surface of workpiece is step surface, add man-hour, fixture is coordinated with milling machine table T-slot by positioning key 12 and is arranged on lathe, workpiece 1 for positioning datum, utilizes the pneumatic shuttle of single effect, when piston 6 is moved to the left with bottom surface and side, promote top pressing board 11 clamping work pieces 1 by simple chain lever 9, carry out follow-up processing.When processing the workpiece of differing heights, only needing the gripper shoe 2 of replacing differing heights and tightening screw 14, convenient and quick, add the scope of application of fixture.
The beneficial effects of the utility model are: the workpiece that conveniently can clamp differing heights, and avoiding affects working (machining) efficiency because changing fixture, use relatively more flexible, add the scope of application of fixture.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in the technical field that other are relevant, be all in like manner included in scope of patent protection of the present utility model.
