Abstract
The invention discloses a manual knock-type compressing clamp. The manual knock-type compressing clamp comprises a support with a vertical mounting hole and a horizontal mounting hole, wherein a slide shaft is arranged in the vertical mounting hole in a sliding manner, an inclined wedge surface is arranged on the side wall of the slide shaft, an inclined wedge pressure head matched with the inclined wedge surface is arranged in the horizontal mounting hole in a sliding manner, the dip angle of the right end surface of the inclined wedge pressure head is the same as the dip angle of the inclined wedge surface and ranges from 7 degrees to 9 degrees, a lever used for levering the slide shaft is mounted on the lower side wall of the support in a rotating manner, and a reset spring used for resetting the inclined wedge pressure head is arranged on the side wall of the support. The manual knock-type compress holder has the following advantages that the clamping force of the manual knock-type compressing clamp is far larger than that of an ordinary manual clamp, the self-locking performance is good, the anti-vibration capability is high, and the manual knock-type compressing clamp is reasonable in design, simple in structure, convenient to operate, small in size, light in weight, convenient to demount and mount, easy to carry, long in service life, wide in application range, low in production cost, and capable of being popularized and used.
Description
Technical field
The invention belongs to Machining Technology field, relate to a kind of fixture, be specifically related to a kind of manually percussive compressing fixture.
Background technology
At present, manual is simple in structure because of it, low production cost, and the advantage such as the manufacturing cycle is short, energy-conserving and environment-protective, is still widely used in modern manufacturing industry.But manual has a fatal shortcoming, due to the force limited of staff, cause its clamping force can not be very large, thereby cannot compare favourably with hydraulic pressure, the motor-driven fixture such as pneumatic.For example, the fixture of high frequencies of operation, General Requirements staff active force is less than 150N; The fixture of low frequency operation, staff active force should be limited in 600N.Otherwise operator's labour intensity is excessive by making.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, a kind of manually percussive compressing fixture is provided, its clamping force is far away higher than common manual fixture, self-locking property is good, and vibration resistance is strong, reasonable in design, simple in structure, easy to operate, volume is small and exquisite, lightweight, easy accessibility, is convenient to carrying, 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 manually percussive compressing fixture, comprise the bearing with vertical installing hole and horizontal installing hole, it is characterized in that: in described vertical installing hole, slide and be provided with slide-bar, described slide-bar sidewall is provided with cammed surface, in described horizontal installing hole, slide and be provided with the wedge pressure head matching with cammed surface, the right side of described wedge pressure head is identical with the inclination angle of cammed surface, the inclination angle scope of the right side of described wedge pressure head and cammed surface is 7 ° ~ 9 °, described bearing lower wall is rotatablely equipped with the lever for prizing slide-bar, described bearing sidewall is provided with the back-moving spring for wedge pressure head is resetted.
Above-mentioned manual percussive compressing fixture, is characterized in that: described back-moving spring is flat spring.
Above-mentioned manual percussive compressing fixture, is characterized in that: described lever is hinged on described bearing.
The present invention compared with prior art has the following advantages:
(1) this manual percussive compressing fixture clamping force, far away higher than common manual fixture, can substitute pneumatic or hydraulically operated fixture within the specific limits.
(2) this manual percussive compressing fixture adopts face contact type wedge self-locking mechanism, and self-locking property is good, and vibration resistance is strong.
(3) this manual percussive compressing fixture is reasonable in design, simple in structure, and the end that operating personnel only need use hammer to knock slide-bar gets final product complete operation, operates very easy.
(4) this manual percussive compressing fixture volume is small and exquisite, lightweight, and easy accessibility is convenient to carrying, and long service life is applied widely.
(5) a lot of parts of this manual percussive 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.
Fig. 2 is the structural representation of bearing of the present invention.
Description of reference numerals:
1-bearing; 1-1-vertical installing hole; 1-2-horizontal installing hole;
2-slide-bar; 2-1-cammed surface; 3-wedge pressure head;

The specific embodiment
The manual percussive compressing fixture of one as depicted in figs. 1 and 2, comprise the bearing 1 with vertical installing hole 1-1 and horizontal installing hole 1-2, in described vertical installing hole 1-1, slide and be provided with slide-bar 2, described slide-bar 2 sidewalls are provided with cammed surface 2-1, in described horizontal installing hole 1-2, slide and be provided with the wedge pressure head 3 matching with cammed surface 2-1, the right side of described wedge pressure head 3 is identical with the inclination angle of cammed surface 2-1, the inclination angle scope of the right side of described wedge pressure head 3 and cammed surface 2-1 is 7 ° ~ 9 °, is preferably 8 °.Described bearing 1 lower wall is hinged with the lever 4 for prizing slide-bar 2, and articulated manner is simple and practical, dependable performance.Described bearing 1 sidewall is provided with the back-moving spring 5 for wedge pressure head 3 is resetted.
As shown in Figure 1, described back-moving spring 5 is flat spring, and flat spring is compared with traditional cylindroid helical-coil compression spring, simple in structure, takes up room less.
The course of work of the manual percussive compressing fixture of the present invention is: as shown in Figure 1, first this manual percussive compressing fixture is fixed on to operating position, workpiece 6 is placed on to wedge pressure head 3 left sides, knock slide-bar 2 upper surfaces with hammer, slide-bar 2 moves down in installing hole, make cammed surface 2-1 compress the right side of wedge pressure head 3, thereby make wedge pressure head 3 be moved to the left workpiece pressing 6, because belonging to Wedge type self-locking with the upper surface of wedge pressure head 3, cammed surface 2-1 coordinates, in the situation that not applying other power, can make the long-time workpiece pressing 6 of wedge pressure head 3.
When workpiece 6 is processed complete after, actuating linkage 4 clockwise rotates, and lever 4 left ends can be by slide-bar 2 jack-up, thereby the right side of cammed surface 2-1 and wedge pressure head 3 is unclamped, wedge pressure head 3 moves right under the effect of back-moving spring 5, thereby takes out the workpiece 6 machining.
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.
