But the plug-type clamping device of existing design easily causes location inaccurate in the process of push-and-pull, and parts can depart from positioning datum.
Summary of the invention
For the problems referred to above, the invention provides a kind of plug-type clamping device, utilize parallelogram lindage motion principle to be clamped by parts, and, in the process of push-and-pull, guarantee that parts can not depart from positioning datum, ensure processing effect.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of plug-type clamping device, it is characterized in that, comprise can with the pull bar of cylinders, be symmetricly set in the first straight rocking bar and the second straight rocking bar of pull bar both sides, described pull bar is provided with the clamping part that can clamp the first straight rocking bar and the second straight rocking bar from top to bottom, the other end of the described first straight rocking bar and the second straight rocking bar is hinged with first connecting rod and second connecting rod respectively, described first connecting rod and second connecting rod are hinged with rocking bar straight with the first first driven clamp parallel with the second straight rocking bar and the second driven clamp respectively, for clamping parts between described first driven clamp and the second driven clamp, first straight rocking bar and the first driven clamp and the first support hinged, second straight rocking bar and the second driven clamp and the second support hinged, described first support and the second support are symmetricly set on pull bar both sides.
Preferably, described clamping part comprises symmetrically arranged upper disk and lower disc.
Preferably, the described first straight rocking bar and the second straight rocking bar are provided with point near the side of pull bar.
When cylinder drives pull bar to move up and down, clamping part drives two straight rocking bars to rotate, and drives the first driven clamp and the second driven clamp to rotate respectively clamped by parts by two connecting rods.The mechanism of pull bar both sides forms parallelogram lindage respectively, and it is symmetrical arranged, size is identical, therefore in the process of push-and-pull, guarantees that parts can not depart from positioning datum, ensures processing effect.
The invention has the beneficial effects as follows: utilize parallelogram lindage motion principle to be clamped by parts, and, in the process of push-and-pull, guarantee that parts can not depart from positioning datum, ensure processing effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of plug-type clamping device of the present invention;
The mark implication of accompanying drawing is as follows:
1: pull bar; 2: the first straight rocking bars; 3: first connecting rod; 4: the first driven clamps; 5: parts; 6: the second driven clamps; 7: second connecting rod; 8: the second straight rocking bars; 9: upper disk; 10: lower disc.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, technical solution of the present invention is described in further detail, can better understand the present invention to make those skilled in the art and can be implemented, but illustrated embodiment is not as a limitation of the invention.
A kind of plug-type clamping device, as shown in Figure 1, comprise the pull bar 1 that can be connected with cylinder (not shown), the first straight rocking bar 2 and the second straight rocking bar 8 being symmetricly set in pull bar 1 both sides, preferably, first straight rocking bar 2 and the second straight rocking bar 8 are provided with point near the side of pull bar 1, as shown in FIG., namely the first straight rocking bar 2 and the second straight rocking bar 8 are less than the other end near one end diameter of pull bar 1, and this kind of structure facilitates drive the first straight rocking bar 2 and the second straight rocking bar 8 in the process of push-and-pull to rotate.
Described pull bar 1 is provided with the clamping part that can clamp the first straight rocking bar 2 and the second straight rocking bar 8 from top to bottom, such as, clamping part can be comprise symmetrically arranged upper disk 9 and lower disc 10, or, symmetrically arranged top board and lower platen.The other end of the described first straight rocking bar 2 and the second straight rocking bar 8 is hinged with first connecting rod 3 and second connecting rod 7 respectively, namely the end of the first straight rocking bar 2 and first connecting rod 3 are articulated with b place, end and the second connecting rod 7 of the second straight rocking bar 8 are articulated with f place, described first connecting rod 3 and second connecting rod 7 be hinged with the first driven clamp 4 respectively at c place and g place and the driven clamp 4 of the second driven clamp 6, first parallel with the second straight rocking bar 8 with the first straight rocking bar 2 with the second driven clamp 6.
For clamping parts 5 between first driven clamp 4 and the second driven clamp 6, in order to ensure clamping effect, at the first driven clamp 4 and the second driven clamp 6, parts 5 side can be provided with clamping part.First straight rocking bar 2 and the first driven clamp 4 and the first support (not shown) hinged, be specially: a place and 2, d place hinged with the first support.Accordingly, the second straight rocking bar 8 and the second driven clamp 6 and the second support (not shown) hinged, be specially: e place and 2, h place hinged with the second support.Described first support and the second support are symmetricly set on pull bar 1 both sides.
Preferably, the first support and the second support are articulated with the center of the first driven clamp 4 and the second driven clamp 6 length direction or the center of the first straight rocking bar 2 and the second straight rocking bar 8 length direction respectively.
For Fig. 1, abcd and efgh of pull bar 1 both sides forms a parallelogram lindage respectively, when cylinder drives pull bar 1 to move up and down, clamping part drives two straight rocking bars to rotate around a place and e place, drives the first driven clamp 4 and the second driven clamp 6 to be clamped by parts 5 around d place and the rotation of h place respectively by two connecting rods.The parallelogram lindage of pull bar 1 both sides, it is symmetrical arranged, size is identical, and therefore in the process of push-and-pull, the first driven clamp 4 is identical with the angle that the second driven clamp 6 rotates, can guarantee that parts 5 can not depart from positioning datum, ensure processing effect.
