Abstract
The invention discloses double-jaw pliers the two movable jaw bodies of which can move independently. The double-jaw pliers comprise a pedestal, wherein the pedestal is provided with a movable plier seat and a fixed jaw seat; the fixed jaw seat is provided with a pair of fixed jaw bodies; the movable plier seat and the fixed jaw seat are respectively provided with avoidance slots which cooperate with each other; one side of the movable plier seat is provided with a pair of clamping oil cylinders; the piston rods of the two clamping oil cylinders are connected with a pair of guide bars in a one-to-one correspondence mode, wherein the guide bars movably penetrate through the movable plier seat; the ends of the guide bars are respectively provided with a movable jaw body; and avoidance clearances, which cooperate with the avoidance slots, are respectively arranged between the movable jaw bodies and between the fixed jaw bodies. No matter how the pliers are worn, the jaws on the two sides can tightly clamp objects; and similarly, the pliers can also tightly clamp irregular objects. The pliers are more suitable for parts with particular appearance shapes, and can keep the clamping force and precision for the products the appearances of which are in a staircase or irregular shape.
Description
Technical field
The present invention relates to a kind of clamp, refer more particularly to a kind of double-jaw pliers.
Background technology
At present, double-jaw pliers is the clamp that single oil cylinder is derived, its structure comprises: base, base is provided with moving clamp seat and decides the jaw seat, decide the jaw seat and be provided with a pair of jaw body of deciding, move the clamp seat and decide to offer respectively on the jaw seat avoiding seam that cooperatively interacts, one side of moving clamp seat is provided with clamping cylinder, the piston rod of clamping cylinder links to each other with a pair of guide post that activity is located in the moving clamp seat, the end of each guide post is provided with a movable clamp port body, between the movable clamp port body, decide that the gap of dodging of matching with avoiding seam is arranged respectively between the jaw body.In actual use, both sides moving, decide the jaw body in various degree wearing and tearing all can be arranged, and wear intensity is impossible identical.Because a pair of movable clamp port body can only same moved further, thereby after using a period of time, will cause two jaws (corresponding a pair of fixed, movable clamp port body forms jaw) of clamp simultaneously object not to be clamped, have influence on machining accuracy.In addition, this clamp is had relatively high expectations to the regularity of object, can not clamp well if run into less regular object.
Summary of the invention
Technical problem to be solved by this invention is: a kind of double-jaw pliers that two movable clamp port bodies are moved separately is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: double-jaw pliers, comprise: base, base is provided with moving clamp seat and decides the jaw seat, decide the jaw seat and be provided with a pair of jaw body of deciding, move the clamp seat and decide to offer respectively on the jaw seat avoiding seam that cooperatively interacts, one side of moving clamp seat is provided with a pair of clamping cylinder, the piston rod of two clamping cylinders is corresponding one by one continuous with a pair of guide post that activity is located in the moving clamp seat, this end to guide post is respectively arranged with the movable clamp port body, between the movable clamp port body, decide to be respectively arranged with between the jaw body gap of dodging of matching with avoiding seam.
Be provided with the screw mandrel adjusting device in the described base, its structure comprises: be movably arranged on the screw mandrel in the base and be opened in gathering sill in the base, the outer end of screw mandrel is provided with regulating handle, and the inboard of screw mandrel is arranged in gathering sill, and is threaded with contiguous block in being slidingly arranged in gathering sill; Described moving clamp seat slides and is movably arranged on the base, and is fixed together with the top of contiguous block.
The invention has the beneficial effects as follows: the present invention links to each other with a movable clamp port body by guide post respectively because two clamping cylinders are housed, and makes two movable clamp port bodies to move separately, promptly itself and corresponding to decide between the jaw body clamp stroke relatively independent.Like this, wearing and tearing in any case, the jaw of both sides can both hold object very tight; Equally, this clamp also can hold the irregularity object very tight.
