The automatic clamping device comprises a clamp body, a left clamping jaw, a right clamping jaw, a push rod with a groove, two ejection rods, and a rolling column, wherein a horizontal blind hole is formed in the lower part of the clamp body; a V-shaped hole is formed above the blind hole, and the lower part of the V-shaped hole is communicated with the blind hole; a horizontal workbench is arranged above the clamp body; the middle parts of both the left clamping jaw and the right clamping jaw are symmetrically hinged on the left and the right edges thereof; the upper parts of the clamping jaws are used for pressing a workpiece, and the lower parts are respectively hinged with the two ejection rods; the two ejection rods are respectively placed in the V-shaped hole; an ejection rod spring is sheathed on the ejection rods for keeping the left and the right clamping jaws in the open state; the push rod is inserted into the blind hole; the rolling column is placed above the groove and butts against the two ejection rods; and a push rod spring is arranged between the push rod and the blind hole and is used for driving the push rod to compress the rolling column and the two ejection rods so as to keep the two clamping jaws in the close state. The automatic clamping device provided by the invention has the characteristics of good clamping effect and automatic clamping.
Description
Technical field
The present invention relates to a kind of device of clamping work pieces, be specifically related to a kind of automatic clamping device.
Background technology
Nowadays clamping device is used to a plurality of fields, comprise machinery, carpenter etc., different clamping devices can be applicable to different process requirements, and clamping device is mainly used in clamping and the location of workpiece, so that workpiece obvious displacement does not occur adding man-hour, thereby improve machining accuracy.
On-the-spot in small-scale workshops, because the restriction of cost, the general ingenious effect of utilizing the combinations such as lever, spring, pulley, cam, handle to reach clamping work pieces of clamping device, although solved to a certain extent the clamping problem in the process, but because the locking process is the manually-operated apparatus, the many human errors that can't avoid so bring.
Summary of the invention
The technical problem to be solved in the present invention provides effective, the self-holding automatic clamping device of a kind of clamping.
In order to solve the problems of the technologies described above, the invention provides a kind of automatic clamping device, comprise chuck body, a left side that is used for the workpiece pressing upper surface, right jaw, the push rod with groove as force application apparatus, two push rods as transmission device, roller, wherein, the chuck body bottom has the blind hole of level, above blind hole, be provided with V shaped hole, the V shaped hole bottom communicates with blind hole, the chuck body top is provided with horizontal table, left, right jaw middle part symmetry is hinged on workbench the right and left, its top driven end is used for workpiece pressing, its underpart drive end is hinged with two push rods respectively, and two push rods place in the V shaped hole respectively, and cover has the left side of maintenance, right jaw is in the push rod spring of the trend of opening, described push rod inserts in the blind hole, roller is placed on the groove top, and offsets with two push rods, is provided with push rod spring between described push rod and blind hole, this push rod spring drives push rod extruding roller and two push rods, makes a left side, right jaw keeps clamping trend.
Adopt the automatic clamping device of technique scheme to have following advantage: 1, owing to adopted the symmetrical clamping of mechanical type, unclamping with the transmission that clamps of left and right jaw all concentrated in the motion of same roller, so therefore the synchronized movement of left and right jaw clamps effective; 2, owing to adopted spring locking, the elastic force of spring has replaced artificial thrust when clamping, so clamping process is Automatic-clamping, has avoided to a great extent human error.
As preferred version, consider that push rod needs to move in the effective exercise scope, avoid it to make the inefficacy that cooperates of groove and roller because of rotation, described push rod is provided with the axial limiting groove, and matches on the chuck body, is used for limiting the spacer pin of pushrod movement scope.
Description of drawings
Fig. 1 is the structural representation of embodiment of the invention automatic clamping device.
The specific embodiment
Below in conjunction with drawings and Examples technical solution of the present invention is further specified:
As shown in Figure 1, the invention provides a kind of automatic clamping device, comprise chuck body 1, a left side that is used for the workpiece pressing upper surface, right jaw 4, the push rod 2 with groove as force application apparatus, two push rods 5 as transmission device, roller 7, wherein, chuck body 1 bottom has the blind hole of level, above blind hole, be provided with V shaped hole, the V shaped hole bottom communicates with blind hole, chuck body 1 top is provided with horizontal table, left, right jaw 4 middle part symmetries are hinged on workbench the right and left, its top driven end is used for workpiece pressing, its underpart drive end is hinged with two push rods 5 respectively, two push rods 5 place respectively in the V shaped hole, and cover has the left side of maintenance, right jaw 4 is in the push rod spring 6 of the trend of opening, push rod 2 inserts in the blind hole, roller 7 is placed on the groove top, and offset with two push rods 5, be provided with push rod spring 3 between push rod 2 and blind hole, this push rod spring 3 drives push rod extruding roller 7 and two push rods 5, make a left side, right jaw 4 keeps clamping trend, be provided with stopper slot on the push rod 2 in addition, chuck body 1 is provided with the spacer pin with its coupling, and it is mobile in effective range to limit push rod 2 with this.
Concrete using method is: under the normality because the effect of push rod spring 3, groove is with roller 7 jack-up upwards, if promote inward push rod 2, roller 7 just falls into inside grooves, two push rods 5 move downward along V shaped hole under 6 effects of push rod spring simultaneously, drive respectively left, right jaw 4 rotations, put into workpiece this moment, then unclamp push rod 2, under the effect of push rod spring 3, push rod 2 outwards moves, thereby driving roller 7 moves upward, two push rods 5 are subject to the extruding of roller 7, so move upward along V shaped hole, drive respectively left, right jaw 4 opposite spins, the Automatic-clamping workpiece, wherein because cooperating of spacer pin and stopper slot defines the range of movement of push rod 2, avoided coming off and self rotation of push rod 2.
Above-described only is preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
