Abstract
The invention discloses a pneumatic milling jig. The pneumatic milling jig comprises an air distributing valve arranged on a jig body, wherein the air distributing valve is connected with an air cylinder through a connection pipeline, a piston is arranged in the air cylinder, the tail end of a piston rod is connected with a single hinged lever through a roller, the other end of the lever is connected with an up pressing plate for compacting the surface of a work piece, and a support block is arranged between the bottom of the roller and the jib body. Preferably, a locating key is arranged on the jig body which is connected with a T-shaped groove on a milling machine table through the locating key. The pneumatic milling jig is specially used for clamping the work piece on a step surface, simple in structure, good in clamping effect, and convenient to exchange.
Description
Technical field
The present invention relates to a kind of 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.
The present inventor, according to working experience for many years, designs a kind of pneumatic fraise jig, and be specifically designed to the workpiece of clamping in step surface, structure is simple and clamping effect is good, is convenient for changing.
Summary of the invention
For the problems referred to above, the invention provides a kind of pneumatic fraise jig, be specifically designed to the workpiece of clamping in step surface, structure is simple and clamping effect is good, is convenient for changing.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of 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, and the other end of described lever is connected with the top pressing board for workpiece pressing surface, is provided with back-up block between the bottom of described roller and clamp body.
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.
The invention has the beneficial effects as follows: a kind of pneumatic fraise jig, be specifically designed to the workpiece of clamping in step surface, structure is simple and clamping effect is good, is convenient for changing, uses more flexible.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of pneumatic fraise jig of the present invention;
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.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, technical solution of the present invention is described in further detail, can better understand the present invention to make those skilled in the art and can be implemented, but illustrated embodiment is not as a limitation of the invention.
A kind of 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.
