Abstract
The utility model relates to a clamping device, specifically to an automatic clamping device comprising a clamp body, a clamping jaw used for clamping a workpiece, a connecting rod serving as a force-applying device, a slide rod and a slider. The clamping jaw is hinged to the clamp body; the lower end of the clamping jaw is connected fixedly with the left end of the slide rod; the right end of the slide rod and the upper end of the slider are separable inclined surfaces; the right end of the connecting rod is provided with a hole; a strong spring is disposed in the hole; a wedge-shaped groove is disposed in the middle of the connecting rod; the lower end of the slider is disposed in the wedge-shaped groove; and a resetting spring is sleeved on the slide rod. The automatic clamping device is simple in structure, easy to operate and low in cost.
Description
Technical field
The utility model relates to a kind of clamping device, is specifically related to a kind of self-holding device.
Background technology
Generally when machining, part to be processed all will be fixed, and clamping device plays crucial effects when machining.
Though present clamping device is of all kinds, still have following deficiency in the use of reality: 1, a lot of clamping devices adopt cylinder, hydraulic cylinder device to promote, and cause cost higher; 2, a lot of clamping device complex structures are not easy to operate, to operator's requirement height.
The utility model content
The technical problems to be solved in the utility model provides low, simple in structure, the easy to operate automatic clamping device of a kind of cost.
In order to solve the problems of the technologies described above, the utility model provides a kind of automatic clamping device, comprises chuck body, is used for jaw, the connecting rod as force application apparatus, slide bar, the slide block of clamping work pieces; Wherein jaw is hinged on the chuck body, fixedly connected with the slide bar left end in the lower end of jaw, the upper end of slide bar right-hand member and slide block is separable inclined-plane, described connecting rod right-hand member is provided with a hole, be provided with brute spring in the hole, the middle part is provided with wedge-shaped slot, and the lower end of slide block places in the wedge-shaped slot, also is with back-moving spring on the described slide bar.
Adopt the clamping device of technique scheme to have following advantage: 1, because this clamping device is simple in structure, so operate conveniently; 2, because the type of drive that this clamping device adopts is manual drives, so cost is lower.
As preferred version, when considering the brute spring compression, may be because the pressure of spring causes the brute spring bending, so be provided with a shoulder hole that can prevent the brute spring bending at connecting rod.
As preferred version, consider that connecting rod may rotate and cause workpiece slide block when unclamping to withdraw from along with wedge-shaped slot, so the rotation of a spacer pin limiting rod is installed in the lower end of connecting rod.
Description of drawings
Fig. 1 is the utility model embodiment automatic clamping device structural representation.
The specific embodiment
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
As shown in Figure 1, the utility model provides a kind of clamping device, comprises chuck body, is used for jaw 1, the connecting rod 3 as force application apparatus, slide bar 2, the slide block 5 of clamping work pieces; Wherein jaw 1 is hinged on the chuck body, fixedly connected with the left end of slide bar 2 in the lower end of jaw 1, the upper end of the right-hand member of slide bar 2 and slide block 5 is separable inclined-plane, the right-hand member of connecting rod 3 is provided with shoulder hole, is provided with brute spring 4 in the hole, and the middle part of connecting rod 3 is provided with wedge-shaped slot, the lower end of slide block 5 places in the wedge-shaped slot, also be with back-moving spring 6 on the slide bar 2, in addition, below connecting rod 3, also be provided with spacer pin.
Under normal conditions, brute spring 4 automatically springs open, and brute spring 4 promotes connecting rod 3 levels and is moved to the left, slide block 5 is along with wedge-shaped slot moves up, and slide block 5 drives slide bar 2 and is moved to the left, back-moving spring 6 compressions, the lower end of jaw 1 is moved to the left, the upper end of jaw 1 clamping work pieces that moves right; Promote connecting rod 3 to the right, slide block 5 is along with wedge-shaped slot withdraws from, and back-moving spring 6 flicks, and slide bar 2 moves right, and the lower end of jaw 1 moves right, and the upper end of jaw 1 is moved to the left unclamps workpiece.
Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
