Abstract

The utility model belongs to the technical field of mechanical clamps, and relates to a hold-down device for rapidly holding down a workpiece. The device comprises an L-shaped press plate, a fixed handle hold-down screw, a support seat, a bolt and a hinge shaft, wherein one end of the L-shaped press plate is hinged with the support seat by the hinge shaft; dowel holes are opened in the L-shaped press plate and the support seat; location can be carried out by the bolt; and the fixed handle hold-down screw is installed at the other end of the L-shaped press plate. The rapid hold-down device disclosed by the utility model is installed together with the hinge shaft, and then the whole device is integrally installed on a cutting die body; rapid hold-down and release for the workpiece which is held down can be realized, thus facilitating the operation of a worker and greatly increasing the working efficiency; high-quality fixation for composite material combined workpieces with irregular shapes such as complex shape surfaces, large radian and the like is realized.

Description

A kind of fast compressing device

Technical field

The invention belongs to mechanical clamp technical field, relate to the hold down gag for fast-holding workpiece.

Background technology

In many types, there are many large-scale composite material elements, out-of-shape, there is inserts centre, so have many positions, irregular hole, deburring can not meet batch requirement of producing by hand, and manual deburring is neat not, accurately, so just must be designed for the frock of Numerical control cutting, so will consider the clamping problem of workpiece, fast fixture in standard component, more applicable for milder workpiece, but larger for radian, the workpiece that difference in height is higher has certain limitation, now dodge for adopting traditional fast compressing device just must carry out partial operation to die body, thereby cause the difficulty of design and die body processing and manufacturing, sometimes because the limited size of die body, can bring more loaded down with trivial details work, even cause the waste of rapidoprint, increase manufacturing cost.So this invention has solved above-mentioned clamping problem.

Summary of the invention

The purpose of this utility model is: a kind of easy to operate, the hold down gag that can realize fast-holding, dismounting is provided.

The technical solution of the utility model is: a kind of fast compressing device, and it comprises L-type pressing plate, fixed handle housing screw, bearing, latch and hinge axis;

L-type pressing plate one end is hinged by hinge axis and bearing, and L-type pressing plate and bearing all have pin hole, can locate by latch, and the L-type pressing plate other end is equipped with fixed handle housing screw.

Described hinge axis termination has a screwed hole, and a Screw, through this screwed hole fixed hinge axle, avoids hinge axis to depart from from bearing.

The utility model has the advantages that: the utility model fast compressing device is installed together by hinge axis, then whole device integral installation is on cutting die body, can realize fast-holding and the loose unloading to workpiece pressing, be convenient to workman's operation and greatly increase work efficiency, having realized the irregular composite combination workpiece of the profile high-quality such as external surface complexity, large radian are fixed.

Detailed description of the invention

Below the utility model is described in further details.

Please be simultaneously referring to Fig. 1, Fig. 3, Fig. 4 and Fig. 5, wherein, Fig. 1 is the view of the utility model fast compressing device on blanking punch; Fig. 3 is 3-D view of the present utility model; Fig. 4 is the detailed front view of the utility model fast compressing device; Fig. 5 is the detailed top view of the utility model fast compressing device.Described compression Quick-disassembling device comprises 1 L-type pressing plate, 1 fixed handle housing screw, 1 bearing, 4 screws, 1 latch and 1 hinge axis.Wherein, hinge axis is made up of a screw and packing ring, in the middle of hinge axis termination, has opened a screwed hole, first places a packing ring in hinge axis termination, then plugs a Screw fixed hinge axle, avoids hinge axis to depart from from bearing.Refer to Fig. 3, it is the 3-D view of the utility model fast compressing device in the time of workpiece pressing.

Using method of the present utility model is: first operating personnel link up L-type pressing plate by hinge axis component and bearing, with four screws respectively handle assembly be fixed on die body, put composite material work piece well, then plug latch, the fixed handle housing screw of screwing on again, be adjusted to the position that workpiece pressing is suitable, complete the clamping work of workpiece, then carry out altogether a series of operation elements that need.

In the time that needs unload workpiece, workman only need to pull out latch, rotates L-type pressing plate, just can take away composite wood workpiece, then changes workpiece, and whole clamping device does not need dismounting, realizes quick continuous productive process, thereby significantly improves dismounting speed, increases work efficiency.
