Description
Technical field
The utility model relates to a kind of positioning clamping device.
Background technology
In the prior art, it is CL-MF40-5301 that Carr Lane company discloses a kind of model, be called the positioning clamping device structure (as shown in Figure 1) of pressing folder (Up-ThrustClamps), the regular jaw 21 and the moved jaw 22 of lower end and the cam pressure handle 11 that is used for adjusting and controlling moved jaw grasp opening size that comprise the upper end, should go up the locating surface 211 of pressing clamping to decide jaw 21 and keep certain height, corresponding with this locating surface, the moved jaw 22 of lower end has the jaw clamping area 221 and 222 of two differing heights respectively, screw by rotation, the jaw clamping area 211 of clamping thickness of workpiece or the locating surface 211 of 222 secured in alignment jaws 21 will be fit to, pull members such as the joint bolt 12 of pressing rotating cam pressure handle 11 to drive to interconnect cooperation and nut 13 then, and then the locating shaft 14 that is connected with moved jaw 22 of drive, so that moved jaw 22 can be located up and down is mobile, realize the operation of height up and down of control moved jaw clamping area.Pressed anchor clamps that one highly relatively-stationary regular jaw locating surface 211 (going up pressure surface) is arranged owing to should go up, so it can be used to keep the horizontal location of pressure surface on the workpiece; Example application as shown in Figure 2, it is smooth and the lower end has the location of irregular thickness workpiece 3 to be used for the upper end, select for use two to go up the pressure folder, with the corresponding respectively regular jaw locating surface 211 (promptly going up pressure surface) of pressing folder of going up of facade on these workpiece two ends, select for use suitable moved jaw clamping area 221 and 222 to position respectively according to the difference of workpiece 3 two-end thickness again, after adjustment cam pressure handle 11 clamping and positioning, the last facade of workpiece 3 is bound to keep level.But owing to should go up the press-clamping structure design cooperation of workpiece inside was had relatively high expectations, and it to be positioned in the expensive welding bench locating hole when using,, be unfavorable for promoting the use of so its use cost and supporting cost and processing cost are all higher.
The utility model content
It is lower that technical problem to be solved in the utility model is to provide a kind of simple in structure, with low cost, environment for use to require, and can realize the positioning clamping device of its set function substantially, its technical problem to be solved can be implemented by the following technical programs.
A kind of positioning clamping device, the regular jaw that comprises device body and base thereof and be located at the device body upper end, described regular jaw has a pressure surface last pressure surface down, described positioning clamping device comprises that also one has and the described moved jaw structure that goes up the tight face of the corresponding drought of pressure surface, described moved jaw structure is a lever construction, the fulcrum of described lever construction articulates by rotating shaft and device body, power arm one end of described lever construction is provided with one and screws application of force screw rod, and resistance arm one end of described lever construction is provided with described corresponding clamping area.This positioning clamping device substitutes labyrinth of the prior art by lever construction, thereby has correspondingly reduced production cost under the situation that assurance function is not lost.
Described clamping area can be the presser feet face of a unsteady presser feet.The floating property of presser feet makes effectively have been dissolved because the inconvenience that the lever displacement is brought by floating of presser feet in different clamping process.
As the further improvement of the technical program, can be arranged with the compression spring that resets described screwing on the application of force screw rod.This compression spring helps resetting of under unclamped state lever positions and to the pre-clamping of workpiece.
And on the device body of described positioning clamping device, can offer one group of grafting locating hole with differing heights, this grafting locating hole is used for articulating the pivot shaft of described lever construction, under different needs, assigning in the grafting locating hole of differing heights by pivot shaft with lever, thus realize preferably, clamp or the location more easily.
On described base, be provided with U type mounting groove, be used for finishing this positioning clamping device fixing on table top.
Further, by described clamping area is made as non slip surface,, help clamping to strengthen friction.
In addition, rotary handle can be set, be beneficial to operation at described application of force screw rod one end.
Also,, realize control on the float rotation axle of described unsteady presser feet, prevent under its random swing situation picking and placeing of holding workpiece to be formed interference the presser feet hunting range by the damping unit of restriction presser feet swing degree is set as extra improvement.
Adopt the positioning clamping device of this technical scheme simple in structure, with low cost, and versatility is stronger.
