Description
[technical field]
The utility model relates to a kind of instrument that vehicle body manufacturing field is welded and uses on the line, relates in particular to a kind of clamping tool.
[background technology]
For general anchor clamps, its basic structure is driven by cylinder 104 as shown in Figure 1, locating piece 102 location, and pressing plate 101 clamps, and stretching out and withdrawing of cylinder 104 makes pressing plate 101 be in the state that clamps and unclamp respectively.Because locating piece 102 tightens together with fork group 103, remains static, then horizontal positioned is answered on the maximum surface of part, could the vertical direction from locating surface withdraw from after welding.Because it is that side direction is placed that many parts are arranged on the vehicle body, so just must increase other motion auxiliary clamp and withdraw from postwelding; Make structure complicated like this, increase location unstability and production cost.
[utility model content]
In order to solve the problems of the prior art, the utility model provides a kind of two-way clamping device, comprise cylinder, drive rod, gripper shoe, sliding shoe, two first connecting rods, two second connecting rods, two locating pieces, described cylinder is connected with described drive rod, described sliding shoe is fixedlyed connected with described drive rod, described sliding shoe and described drive rod are arranged on described gripper shoe inside, described two first connecting rods, two second connecting rods, two locating pieces are symmetrically distributed respectively, the two ends of described first connecting rod respectively with sliding shoe, second connecting rod is hinged, and described locating piece is fixed on the second connecting rod.
As further improvement of the utility model, described gripper shoe center is provided with rectangular channel, and the width of described rectangular channel matches with the width of described sliding shoe, allows described sliding shoe to slide just.
As further improvement of the utility model, described sliding shoe and described drive rod are integral structure.
As further improvement of the utility model, described first connecting rod is a straight-bar.
As further improvement of the utility model, described second connecting rod is the knee that has two corners.
As further improvement of the utility model, described second connecting rod and described locating piece design for integral type.
The utility model is owing to first connecting rod and second connecting rod symmetric arrangement, and from the middle clamping of two side direction, locating piece is opened simultaneously when opening, and dodges the bigger lifting that makes things convenient for part in space.Sliding shoe slides along the rectangular channel at gripper shoe center, can find center line automatically accurately, and error is less, has guaranteed the positioning accuracy to part.This device clamp mechanism is the reinforcement linkage, and this mechanism can obtain bigger clamping force in the same cylinder power output.This equipment mechanism is simple, saves production cost.This device is easy for installation, and it is less to take up room.

[specific embodiment]
Below in conjunction with the description of drawings and the specific embodiment the utility model is further specified.
As shown in Figure 2, for breaking through the restriction of prior art, need make between pressing plate and the locating piece has relative motion, locating piece and pressing plate is drawn close to the center simultaneously, and opened to both sides simultaneously when opening, and avoids the part interference that causes because of lifting.The utility model provides a kind of reinforcement hinge type two-way clamping device for this reason.A kind of two-way clamping device, comprise cylinder 1, drive rod 2, gripper shoe 3, sliding shoe 4, two first connecting rods 5, two second connecting rods 6, two locating pieces 7, described cylinder 1 is connected with described drive rod 2, described sliding shoe 4 is fixedlyed connected with described drive rod 2, described sliding shoe 4 is arranged on described gripper shoe 3 inside with described drive rod 2, described two first connecting rods 5, two second connecting rods 6, two locating pieces 7 are symmetrically distributed respectively, the two ends of described first connecting rod 5 are hinged with sliding shoe 4, second connecting rod 6 respectively, and described locating piece 7 is fixed on the second connecting rod 6.Described gripper shoe 3 centers are provided with rectangular channel, and the width of described rectangular channel matches with the width of described sliding shoe 4, allow described sliding shoe 4 to slide just.
As shown in Figure 3, be this device clamp mechanism schematic diagram.Promote drive rod when clamping cylinder, the sliding shoe that is fixed on the drive rod upwards slides along the rectangular channel at gripper shoe center, drive the pin joint of first connecting rod that is hinged on the sliding shoe simultaneously and turn clockwise, and second connecting rod being fixedly hinged on gripper shoe under the effect of first connecting rod a little is rotated counterclockwise around the second connecting rod bottom; Because first connecting rod and second connecting rod are symmetric arrangement, the locating piece that is fixed on the second connecting rod is realized the location of part is clamped in the relative motion of second connecting rod.Otherwise, clamping cylinder and return, this device is in open mode.
Innovation point:
1, since first connecting rod and second connecting rod symmetric arrangement, sliding shoe along the rectangular channel slip at gripper shoe center, this device can be found center line accurately automatically, error is less, has guaranteed the positioning accuracy to part.
2, from the middle clamping of two side direction, locating piece is opened simultaneously when opening, and dodges the bigger lifting that makes things convenient for part in space.
3, this device clamp mechanism is the reinforcement linkage, and this mechanism can obtain bigger clamping force in the same cylinder power output.This equipment mechanism is simple, saves production cost, and easy for installation, it is less to take up room.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
