Abstract
The invention discloses a clamp with adjustable length, which comprises clamp bodies, a screw rod, a clamp head and a hand lever, and is characterized in that the clamp further comprises a sliding rod; and the number of the clamp bodies is two, and each clamp body is in the shape of L and can slide and be positioned on the sliding rod. The clamp has the beneficial effects that the clamp with the adjustable length can be adjusted according to the length of a clamped workpiece, and one clamp can clamp the workpieces in different sizes, thereby greatly reducing the specification of the clamp, and lowering the manufacturing cost and the using cost. The clamp has the characteristics of simple structure, easiness in operation, wide application range and the like.
Description
Technical field
The present invention relates to a kind of anchor clamps, be specifically related to a kind of length-adjustable anchor clamps, belong to the clamping device technical field.
Background technology
The workpiece that often has some to be uneven in length in factory if the workpiece of every kind of length all designs a kind of anchor clamps, will cause anchor clamps quantity to increase, and increases cost.
Summary of the invention
The invention provides a kind of length-adjustable anchor clamps, it can be adjusted according to the length of workpiece, reduces anchor clamps quantity.
The technical solution adopted for the present invention to solve the technical problems is: a kind of length-adjustable anchor clamps, comprise clamp, screw rod, chuck, hand lever, and it also comprises slide bar; Described clamp has two, and is L-shaped, and the upper end of described L shaped clamp is provided with the slide opening of horizontal direction, and the lower end is provided with boss, is provided with round open-work perpendicular to the side of slide opening; The described slide bar shape that is in line, the centre is provided with the screwed hole of vertical direction, and described slide bar side also is provided with several isometric circle open-works vertically; Described slide bar upper screwed hole is connected with screw flight, and described screw rod lower end is equipped with chuck, and the screw rod upper end is provided with horizontal round open-work, the movable hand lever of placing in the circle open-work; Described L shaped clamp upper end slide opening and slide bar shape of cross section adapt, and described two L shaped clamps are put into slide bar relatively from two ends, and slide opening and slide bar are matched in clearance; Described clamp is the same with circle open-work size on the slide bar perpendicular to the round open-work of slide opening side, and the circle open-work can be corresponding with arbitrary round open-work on the slide bar on the clamp, inserts split pin then and fix.
Further, on the described slide bar side between the circle open-work distance between 10～20mm, change.
Further, the cross section of described slide bar and slide opening is a rectangle.
The invention has the beneficial effects as follows, this length-adjustable anchor clamps, can adjust according to the length of clamping workpiece, but different workpiece of anchor clamps clamping size, thereby reduced the specification of anchor clamps greatly, reduce manufacturing expense and cost of use, had characteristics such as simple in structure, processing ease, adaptation be wide.

The specific embodiment
As shown in Figure 1 and Figure 2, a kind of length-adjustable anchor clamps comprise clamp 5, screw rod 1, chuck 6, hand lever 7, also comprise slide bar 3, described clamp 5 be two L-shaped, the upper end of described L shaped clamp 5 is provided with the slide opening of horizontal direction, the lower end is provided with boss 4, is provided with round open-work perpendicular to the side of slide opening; Described slide bar 3 shape that is in line, the centre is provided with the screwed hole of vertical direction, and described slide bar 3 sides also are provided with several isometric circle open-works vertically; Described slide bar 3 upper screwed holes are threaded with screw rod 1, and described screw rod 1 lower end is equipped with chuck 6, and screw rod 1 upper end is provided with horizontal round open-work, the movable hand lever 7 of placing in the circle open-work; Described L shaped clamp 5 upper end slide openings and slide bar 3 shape of cross sections adapt, and described two L shaped clamps 5 are put into slide bar 3 relatively from two ends, and slide opening and slide bar 3 be matched in clearance, so that clamp 5 move left and right.Described clamp 5 is the same with circle open-work size on the slide bar 3 perpendicular to slide opening side circle open-work, and the circle open-work can be corresponding with arbitrary round open-work on the slide bar 3 on the clamp 5, inserts split pin 2 then and fix.Justify on described slide bar 3 sides between the open-work apart between 10～20mm, changing.The cross section of described slide bar 3 and slide opening is a rectangle.
During work, at first adjust the relative distance of two clamps 5, allow the round open-work on the clamp 5 relative then, insert split pin 2, afterbody is broken into two with one's hands with round open-work on the slide bar 3 according to Workpiece length.The workpiece lower plane is put on two boss 4, and hand lever 7 is rotated on plane on chuck 6 alignment pieces, and screw rod 1 moves down, chuck 6 workpiece pressings, process workpiece after, counter-rotation hand lever 7 unclamps workpiece, and it is unloaded.
