The installation mode comprises the steps of perforating, arranging bolts for fixing, arranging corresponding installation grooves, and clamping the installation grooves by pneumatic, hydraulic and the like, so that the installation of the clamp is realized. The lower part of the body 1 is extended by two side edges to form a U-shaped groove which is a clamping part, the size of the U-shaped groove can be set according to the specification of a workpiece to be processed, an upper groove 103 and a lower groove 104 are respectively formed in the inner side of the U-shaped groove, the notches of the upper groove 103 and the lower groove 104 are opposite, so that the stress on two sides of the workpiece is uniform, when certain workpieces are processed, the upper groove 103 and the lower groove 104 can be matched and clamped with a lug on the workpiece, and the upper groove 103 and the lower groove 104 can also be used for increasing a non-slip mat made of rubber materials to the workpiece with flat sides, so that the friction force between the workpiece and the body is increased, and the workpiece is not easy to drop. In clamping part, in the U groove promptly, be close to this one side of front panel and locking handle, be equipped with a notch 102 that is used for installing layering 5 in the U groove, be equipped with the through-hole in the notch 102, run through to the upper portion of body 1, the through-hole is equipped with a plurality of, part is used for through bolted connection layering 5, be equipped with the screw thread on layering 5, can be used to the connection of bolt, the through-hole that part is slightly bigger can be used to the setting of knock pin 9, the outside parcel of knock pin 9 sets up the spring, then the top is inconsistent with front panel 2 again, front panel 2 sets up bellying 202 in both sides, such structure makes the middle part can the indent, conveniently form the clearance, the protrusion of second both sides also is convenient to be embedded in the position department that corresponds knock pin 9, easy to assemble, and be used for the spacing of spring. The spring is located the outside of body, and one end is contradicted on the body, and one end offsets with the top of knock pin 9, so makes knock pin 9 pull out in the through-hole to jack-up front panel 2 upwards. Further, the bolts of the front panel 2 are fixedly connected with the pressing bar 5, so that the pressing bar 5 is also retracted upwards into the notch 102, and the state is a non-clamping state of the workpiece. Then, in order to achieve clamping, the front panel 2 should be forced downwards, against the spring force on the ejector pin 9, the bead 5 downwards, which is the clamped state of the workpiece. For the pressing strip 5, the workpiece 8 is clamped by the toothed structure, the toothed structure 501 can be made of plastic, elasticity is improved, and the workpiece 8 is not easy to damage. For the control of the front panel 2 downwards, controlled by the locking handle, the operation and structure are described as follows:

as can be seen from the structure shown in fig. 2 and 3, the middle part of the front panel 2 is provided with a screw mounting hole 201, in the present utility model, a bolt and a screw can be used alternatively, in order to facilitate the selection of a mounting structure and a component for a person skilled in the art, in the embodiment, the screw is used for the connection between the front panel 2 and the fixing block 3, the bottom of the screw is fixed on the body 1, the top of the screw is fixed on the fixing block 3, that is, the fixing hole 301 on the illustrated fixing block 3 is used for fixing the screw, the fixing block 3 and the body 1 are relatively stationary before, no relative position change can occur, the middle part of the screw passes through the screw mounting hole 201 on the front panel 2, the front panel 2 can move, the moving section is provided as a stroke space for extending and retracting the pressing bar 5, and the front panel 2 is used for controlling the protrusion or retraction of the pressing bar 5 in combination with the functions of the ejector pin 9 and the spring.

The fixed block 3, including the side of body clamping part run through a through-hole, for the through-hole 302, be used for the installation of eccentric part 401, combine fig. 3, eccentric part 401 includes rotatory hole 402, rotatory hole 402 and through-hole 302 alignment installation, and the fixed of bolt, then use rotatory hole 402 or through-hole 302 as the pivot, can rotate, rotatory hole 402 is then the non-circular structure all around, realize eccentric action, including gear-like or oval form, also include other eccentric structures known in the art, still handle mounting hole on the eccentric part 401, be used for connecting the handle, eccentric part 401 includes two sets of, set up in the both ends of fixed block 3.

In connection with the above-described construction, it is added that, in the movement control construction of the front panel 2, one end of the spring is also in abutment with the through hole (the through hole in the slot 102 is provided in a non-cylindrical shape, i.e. the diameter at the outside of the body is large, the diameter at the end of the connecting bead 5 is relatively small, how it is possible to achieve that the spring 10 cannot pass through the through hole, but the lateral movement of the spring can be restricted by means of the through hole with a large diameter so that it has a fixed movement position). For the clamp of the utility model, a sloping block 6 can be arranged below the mounting groove 101, the sloping block 6 is fixed on the body, the sloping block 6 can be used for adjusting the stability of the clamp, the sloping block 6 can enable the clamp to bear force on two sides of the protruding part after being mounted through the mounting groove 101, and the lateral force in the workpiece machining process is limited, and in some embodiments, the clamp can also be understood as the function of a wedge.

In combination with fig. 4 and 5, the locking handle is turned upwards at the position shown in fig. 5, and the front panel and the fixed block are relatively separated to move under the action of the deflection component, and the fixed block is fixed with the body under the action of the screw, so that the front panel is stressed to be attached to the side close to the body, the pressing bar in the notch of the clamping part on the body is pressed down in the attaching process, and the pressing bar is protruded, so that the workpiece is rapidly and manually clamped. After the service time is longer, the deflection component is easier to slip relative to the contact part on the front panel, so that the deflection component automatically falls off, a locking mechanism of the locking handle can be arranged for preventing the locking handle from falling off, for example, a lock catch is added to fix the locking handle, and the eccentric component can be changed into a gear-shaped or other structure with obvious stress turning points (the points are not curved and are preferable in a fold line shape).

Finally, the upper end of the body is used for fixing the body on a numerical control machine tool or processing equipment, the rapid clamping of the workpiece during processing is realized through the design of the handle, and the device is more suitable for processing various flexible nonstandard products, including cutting, bending, drilling and the like of plates.
