The characteristics of the self-locking type wedge compression device are that: through the lever reinforcement mechanism, the drive power of the drive device can be significantly decreased; through a self-locking function, an energy-saving effect is remarkable; and the self-locking type wedge compression device is reasonable in design, is simple in structure, is easy to operate, is good in rigidity, is long in service life, is wide in application range, is low in production cost, and is easy to promote.
Description
Technical field
The invention belongs to Machining Technology field, relate to a kind of fixture, be specifically related to a kind of self-locking wedge hold down gag.
Background technology
When carrying out machining to parts, first compression to be positioned to workpiece to be processed, the workpiece mode of stepping up conventional at present adopts nut bolt to coordinate to be fixed, 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 to compare effort in process, labour intensity is high, and automaticity is low, and enterprise is in a disadvantageous position in same industry competition.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, provide a kind of self-locking wedge hold down gag, it has lever boosting mechanism, significantly can reduce the driving power of drive unit, have auto-lock function, energy-saving effect is remarkable, reasonable in design, structure is simple, 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 self-locking wedge hold down gag, comprising the drive unit for providing driving force, it is characterized in that: also comprising the boosting lever for increasing driving force and the cooperatively interact wedge and wedge pressure head that form self-locking inclined-plane; The clutch end of described drive unit is installed with the boosting block that middle part is provided with vertical slot, described boosting lever one end is arranged in described vertical slot, in the middle part of described boosting lever, upper position is rotatably installed on fulcrum, the described boosting lever other end is arranged in the blind hole in the middle part of wedge, the described wedge pressure head for workpiece pressing is provided with on the downside of described wedge, be provided with back-moving spring on the downside of described wedge pressure head, described drive unit is linear electric motors.
Above-mentioned self-locking wedge hold down gag, is characterized in that: described boosting lever is hinged on fulcrum.
The present invention compared with prior art has the following advantages:
(1) this self-locking wedge hold down gag has lever boosting mechanism, significantly can reduce the driving power of drive unit.
(2) this self-locking wedge hold down gag adopts Wedge mechanism, and have auto-lock function, drive unit can be made when needed to quit work, and energy-saving effect is remarkable.
(3) this self-locking wedge hold down gag is reasonable in design, and structure is simple, and workpiece only need be placed on workbench by operating personnel, and this fixture can complete clamp operation automatically, uses very easy.
(4) this self-locking wedge hold down gag good rigidly, long service life, applied widely.
(5) a lot of parts of this self-locking wedge hold down gag are convenient to produce, buy all very much, and thus 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.

Detailed description of the invention
A kind of self-locking wedge hold down gag as shown in Figure 1, comprises the drive unit 1 for providing driving force, and described drive unit 1 is linear electric motors.Also comprise the boosting lever 3 for increasing driving force and the cooperatively interact wedge 5 and wedge pressure head 6 that form self-locking inclined-plane; The clutch end of described drive unit 1 is installed with the boosting block 2 that middle part is provided with vertical slot 2-1, described boosting lever 3 one end is arranged in described vertical slot 2-1, in the middle part of described boosting lever 3, upper position is hinged on fulcrum 4, described boosting lever 3 other end is arranged in the blind hole 5-1 in the middle part of wedge 5, the described wedge pressure head 6 for workpiece pressing 8 is provided with on the downside of described wedge 5, wedge 5 and wedge pressure head 6 are with the use of having auto-lock function, drive unit 1 can be made when needed to quit work, and energy-saving effect is remarkable.Be provided with back-moving spring 7 on the downside of described wedge pressure head 6, back-moving spring 7 can make wedge pressure head 6 automatically lift, and is convenient to unload the workpiece 8 machined.
The course of work of self-locking wedge hold down gag of the present invention is: first this self-locking wedge hold down gag is arranged on operating position, workpiece to be processed 8 is placed on processing platform, start drive unit 1, the promotion boosting block 2 of drive unit 1 is moved to the left, boosting block 2 drives boosting lever 3 upper end to be moved to the left, boosting lever 3 is rotated counterclockwise around fulcrum 4, boosting lever 3 lower end drives wedge 5 to move right by blind hole 5-1, wedge pressure head 6 moves down under the effect on wedge 5 inclined-plane, thus compress workpiece to be processed 8, after this just machining can be carried out to workpiece to be processed 8, the clamp system formed due to wedge 5 and wedge pressure head 6 has auto-lock function, drive unit 1 can be made in working angles to quit work, energy-saving effect is obvious.
When workpiece 8 is processed complete after, start drive unit 1, and make drive unit 1 antiport, the promotion boosting block 2 of drive unit 1 moves right, and boosting block 2 drives boosting lever 3 upper end to move right, and boosting lever 3 is rotated clockwise around fulcrum 4, boosting lever 3 lower end drives wedge 5 to be moved to the left by blind hole 5-1, wedge 5 and wedge pressure head 6 depart from, and wedge pressure head 6 moves upward under the effect of back-moving spring 7, thus unclamps the workpiece 8 machined.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every above embodiment is done according to the technology of the present invention essence any simple modification, change and equivalent structure transformation, all still belong in the protection domain of technical solution of the present invention.
