Description
Technical field
The invention belongs to Machining Technology field, relate to a kind of fixture, be specifically related to a kind of eccentric cam self-locking compressing fixture.
Background technology
In the time that parts are carried out to machining, first to position compression to workpiece to be processed, the conventional workpiece mode of stepping up is to adopt nut bolt to coordinate to be fixed at present, although this mode is simple and convenient, there is following shortcoming in operator in use: 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, 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, eccentric cam clamp mechanism has obtained application very widely in fixture.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, a kind of eccentric cam self-locking compressing fixture is provided, it has reinforcement function, the driving power that can significantly reduce drive unit, has auto-lock function, and 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 used in the present invention 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 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, is characterized in that: described roller is hinged on lever.
Above-mentioned eccentric cam self-locking compressing fixture, is characterized in that: described eccentric cam is hinged on fulcrum.
The present invention compared with prior art has the following advantages:
(1) this eccentric cam self-locking compressing fixture has 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, can make when needed drive unit 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 be placed on workpiece on workbench, and this fixture can complete 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 are all 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 present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
Description of reference numerals:
1-drive unit; 2-boosting piece; 2-1-vertical slot;
3-lever; 4-fulcrum; 5-eccentric cam;
6-T type pressure head; 7-back-moving spring; 8-roller;

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 end 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, can make when needed drive unit 1 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 are convenient to the workpiece 9 that unloading 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 eccentric cam self-locking compressing fixture of the present invention is: first this eccentric cam self-locking compressing fixture is arranged on to 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 to move right, make lever 3 drive eccentric cam 5 to clockwise rotate 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 in working angles, can make drive unit 1 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 to be moved to the left, and makes lever 3 drive eccentric cam 5 to rotate counterclockwise around fulcrum 4, thereby eccentric cam 5 and T-shaped pressure head 6 upper ends are departed from, T-shaped pressure head 6 moves upward under the effect of back-moving spring 7, thereby unclamps the workpiece 9 having machined.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every any simple modification, change and equivalent structure transformation of above embodiment being done according to the technology of the present invention essence, all still belongs in the protection domain of technical solution of the present invention.
