Description
Technical field
The utility model belongs to the Machining Technology field, relates to a kind of fixture, is specifically related to a kind of eccentric cam self-locking compressing fixture.
Background technology
When parts are carried out machining, at first to position compression to workpiece to be processed, the workpiece mode of stepping up commonly used is to adopt nut bolt to coordinate to be fixed at present, although this mode is simple and convenient, there is following shortcoming in use in the operator: the workpiece pressing time used is long, and production efficiency is low, step up relatively to require great effort in process, labour intensity is high, and automaticity is low, and enterprise is in a disadvantageous position in same industry competition.In common clamp mechanism, the eccentric cam clamp mechanism not only has auto-lock function, also has the enlarging function of power, and has simple in structure and move advantage fast.Therefore, the eccentric cam clamp mechanism has obtained using very widely in fixture.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of eccentric cam self-locking compressing fixture is provided, and it has the reinforcement function, can significantly reduce the driving power of drive unit, have auto-lock function, energy-saving effect is remarkable, reasonable in design, simple in structure, easy to operate, good rigidly, long service life, applied widely, production cost is low, is convenient to promote the use of.
for achieving the above object, the technical solution adopted in the utility model is: a kind of eccentric cam self-locking compressing fixture, comprise drive unit and lever, it is characterized in that: described drive unit end is provided with the boosting piece, described boosting piece middle part is provided with vertical slot, described lever one end is rotatablely equipped with roller, described roller is arranged in vertical slot, the described lever other end is fixedly connected with eccentric cam, described eccentric cam is rotatably installed on fulcrum, described eccentric cam downside is provided with the T-shaped pressure head for workpiece pressing, described T-shaped pressure head downside is provided with back-moving spring.
Above-mentioned eccentric cam self-locking compressing fixture is characterized in that: described drive unit is linear electric motors.
Above-mentioned eccentric cam self-locking compressing fixture, it is characterized in that: described roller is hinged on lever.
Above-mentioned eccentric cam self-locking compressing fixture, it is characterized in that: described eccentric cam is hinged on fulcrum.
The utility model compared with prior art has the following advantages:
(1) this eccentric cam self-locking compressing fixture has the reinforcement function, can significantly reduce the driving power of drive unit.
(2) this eccentric cam self-locking compressing fixture adopts Eccentric earn mechamism to clamp, and has auto-lock function, and drive unit is quit work, and energy-saving effect is remarkable.
(3) this eccentric cam self-locking compressing fixture is reasonable in design, simple in structure, and operating personnel only need workpiece is placed on workbench, and this fixture can be completed clamp operation automatically, uses very easy.
(4) this eccentric cam self-locking compressing fixture good rigidly, long service life, applied widely.
(5) a lot of parts of this eccentric cam self-locking compressing fixture all are convenient to produce, buy very much, thereby its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the utility model is described in further detail.

The specific embodiment
A kind of eccentric cam self-locking compressing fixture as shown in Figure 1, comprise drive unit 1 and lever 3, described drive unit 1 end is provided with boosting piece 2, described boosting piece 2 middle parts are provided with vertical slot 2-1, described lever 3 one ends are rotatablely equipped with roller 8, described roller 8 is arranged in vertical slot 2-1, and roller 8 and vertical slot 2-1 coordinate the problem that has solved well lever 3DOF deficiency.Described lever 3 other ends are fixedly connected with eccentric cam 5, and described eccentric cam 5 is rotatably installed on fulcrum 4, and eccentric cam 5 has auto-lock function, and drive unit 1 is quit work, and energy-saving effect is remarkable.Described eccentric cam 5 downsides are provided with the T-shaped pressure head 6 for workpiece pressing 9, and described T-shaped pressure head 6 downsides are provided with back-moving spring 7, and back-moving spring 7 can make T-shaped pressure head 6 automatically lift, and is convenient to unload the workpiece 9 that machines.
As shown in Figure 1, described drive unit 1 is linear electric motors.
As shown in Figure 1, described roller 8 is hinged on lever 3.
As shown in Figure 1, described eccentric cam 5 is hinged on fulcrum 4
the course of work of the utility model eccentric cam self-locking compressing fixture is: at first this eccentric cam self-locking compressing fixture is arranged on the operating position, workpiece to be processed 9 is placed on processing platform, start drive unit 1, the promotion boosting piece 2 of drive unit 1 moves right, boosting piece 2 drives lever 3 upper ends and moves right, making lever 3 drive eccentric cam 5 clockwise rotates around fulcrum 4, thereby make T-shaped pressure head 6 move down and compress workpiece to be processed 9, after this just can carry out machining to workpiece to be processed 9, because eccentric cam 5 has auto-lock function, thereby drive unit 1 is quit work, energy-saving effect is obvious.
When workpiece 9 is processed complete after, start drive unit 1, and make drive unit 1 antiport, the promotion boosting piece 2 of drive unit 1 is moved to the left, boosting piece 2 drives lever 3 upper ends and is moved to the left, and makes lever 3 drive eccentric cams 5 and rotates counterclockwise around fulcrum 4, thereby eccentric cam 5 and T-shaped pressure head 6 upper ends are broken away from, T-shaped pressure head 6 moves upward under the effect of back-moving spring 7, thereby unclamps the workpiece 9 that has machined.
The above; it is only preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment does, all still belong in the protection domain of technical solutions of the utility model.
