Abstract
The utility model discloses a self-adjusting type pressing device which comprises a hex nut, a tool fixture, and a bolt fixed on the tool fixture. Both sides of a convex part in the middle of the bolt are cut and machined to be flat. An eccentric pressing plate is arranged on the bolt, gaskets are arranged on the lower end face of the eccentric pressing plate, the eccentric pressing plate is connected with the gasket through a strong spring, a cone-face washer is arranged on the upper end face of the eccentric pressing plate 7, and a ball-face washer is arranged between the hex nut and the cone-face washer. The working height of the device can be adjusted by increasing and reducing the gaskets, so that the device is enabled to have university within a certain range. After machining is finished, under the effect of the strong spring, the disassembling of a workpiece can be completed by simply lifting the eccentric plate, and the disassembling is convenient and fast.
Description
Technical field
The utility model relates to a kind of self-interacting type hold down gag, the especially a kind of self-interacting type hold down gag that can fix irregular workpiece.
Background technology
Frock clamp in use needs to be equipped with some accessories usually, is used for the auxiliary clamp effect, such as the pressing plate that the fixing tool anchor clamps are used, and cushion block, protection workpiece; Also have in addition some accessories that shield, as prevent the device that workpiece flies out in rotary course.
At present, usually use pressing plate and bolt as the accessory of frock clamp.The applicant finds through long-term observation and investigation, assists fixing or compression with pressing plate and bolt, has certain limitation.Play the occasion of auxiliary pressuring action for needs, in order to obtain best compression effect, usually need repeatedly adjust the bolt height, the pressing plate level is pressed on the workpiece, thereby make the compression center of gravity can divide equally distribution, inefficiency; And the occasion that shields for needs; particularly in batch production; be the continuity that guarantees to produce; usually claimed apparatus has the ability of quick degree of tightness; and assist compression with pressing plate and bolt; each workpiece of changing all need again be dismantled, compress, and has further reduced operating efficiency.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the applicant has designed a kind of self-interacting type hold down gag through long-term practical exploration.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the utility model adopts is: a kind of self-interacting type hold down gag, comprise hex nut, frock clamp and the double-screw bolt that is fixed on the described frock clamp, described double-screw bolt middle part projection, the two sides cutting, be processed into flat, described double-screw bolt is provided with an eccentric clamp, the lower surface of described eccentric clamp is provided with pad, described eccentric clamp is connected with pad by brute spring, the upper surface of described eccentric clamp 7 is provided with taper faced washer, is provided with spheric washer between described hex nut and the taper faced washer.
Because the effect of spring force when renewal part, need not unclamped the hex nut of compression, manually raise the dismounting that eccentric clamp can be finished workpiece like this.During work, double-screw bolt is fixed in the relevant position of frock clamp, the rotation hex nut compresses the self-regulation of center of gravity by the acting in conjunction finishing device of spheric washer, taper faced washer, eccentric clamp and brute spring.And, by the number of increase and decrease pad, just can regulate the wording depth of this device.
Beneficial effect: the utility model compared with prior art, its beneficial effect is: 1, by the acting in conjunction of spheric washer, taper faced washer, eccentric clamp and brute spring, this device has the effect that automatic adjusting compresses the center; 2, by the number of increase and decrease pad, the working depth of adjustable apparatus makes this device have the interior versatility of certain limit; 3, machine after, under the effect of brute spring, raise eccentric clamp, can finish the dismounting of workpiece, convenient and swift; 4, double-screw bolt middle part projection, the two sides chamfered edge is processed into flat, and the rotation that is easy to like this device is fixed and dismounting, has improved operating efficiency.
Description of drawings
Fig. 1 is a kind of structural representation of self-interacting type hold down gag.
The specific embodiment
Below by a most preferred embodiment, the technical program is elaborated, but protection scope of the present invention is not limited to described embodiment.
As shown in Figure 1, a kind of self-interacting type hold down gag, comprise hex nut 6, frock clamp 5 and be fixed on double-screw bolt 4 on the described frock clamp 5, described double-screw bolt 4 is provided with an eccentric clamp 7, the lower surface of described eccentric clamp 7 is provided with pad 3, described eccentric clamp 7 is connected with pad 3 by brute spring 8, and the upper surface of described eccentric clamp 7 is provided with taper faced washer 2, is provided with spheric washer 1 between described hex nut 6 and the taper faced washer 2.Described double-screw bolt 4 middle part projections, flat is processed in the two sides cutting.
When renewal part, because the effect of brute spring 8 need not unclamped the hex nut 6 of compression, manually raise the dismounting that eccentric clamp 7 can be finished workpiece.During work, double-screw bolt 4 is fixed in the relevant position of frock clamp 5, rotation hex nut 6 is finished the self-regulation that this device compresses center of gravity by the acting in conjunction of spheric washer 1, taper faced washer 2, eccentric clamp 7 and brute spring 8.And, can by the number of increase and decrease pad 3, regulate the wording depth of this device.
