Abstract

The utility model provides a fixture with a punching function. The fixture comprises a fixture base plate, a clamping mechanism and a punching mechanism, and is characterized in that the fixture base plate is a flat plate; and the clamping mechanism and the punching mechanism are arranged on the fixture base plate. The clamping mechanism and the punching mechanism have same positioning reference, so that higher positioning accuracy among each working procedure can be realized.

Description

A kind of frock clamp with punching function

Technical field

The utility model relates to automobile making and frock clamp field, is specifically related to a kind of frock clamp with punching function.

Background technology

In automobile making, frock clamp general main be auxiliary implementation tool as the vehicle body location, guarantee that the position of each parts in three-dimensional coordinate fix, mould is mainly in order to realize the moulding to stamping parts itself.But in some cases, during for example the welding of vehicle side and top cover is produced, for less hole increases mould, there is cost waste problem, therefore can adopts the fixture with punching function to realize the punching function, reduce costs.

At application number: 200920298409.0 and application number: in 200820217382.3 Chinese utility model patent, thin plate blanking and punching device on the auto welding jig and the sheet metal component punch mechanism of automobile welding and assembling clamp are disclosed respectively, but hole punched device is all only disclosed in two patents, in fact the workpiece that is clamped in these fixtures relates to two operations at least in process, for example welding and punching, need to guarantee that pad, clamping point, three operating point positioning relations of punching point are accurate, the positioning relation problem in how guaranteeing to process is not resolved.

The utility model content

The purpose of this utility model is to provide a kind of frock clamp with punching function, and the clamp mechanism of this fixture and punch mechanism have identical positioning datum to realize having higher positioning accuracy between each operation.

For achieving the above object, the utility model provides following technical scheme:

A kind of frock clamp with punching function comprises:

Fixture substrate;

Clamp mechanism;

Punch mechanism;

It is characterized in that, described fixture substrate is dull and stereotyped, and described clamp mechanism and described punch mechanism are arranged on described fixture substrate.

Preferably, described punch mechanism comprises cylinder, crank mechanism, drift, die and supporting seat, described crank mechanism pin is connected on described supporting seat, and described crank mechanism one end connects the piston rod of described cylinder, the other end connects described drift, and described die is fixed on position corresponding with described drift on described supporting seat.

Preferably, the gauge tap of described cylinder is arranged on described fixture substrate.

Because fixture substrate is dull and stereotyped, clamp mechanism and punch mechanism are arranged on fixture substrate, therefore can be with fixture substrate as common working standard face.The height of clamp mechanism is adjustable, and the position of holding workpiece is also adjustable, and punch mechanism also can be adjusted by cushion block etc., therefore can realize the position relationship accurate positioning of solder joint, clamping point, punching point.

Further, punch mechanism adopts pneumatic form, utilizes crank mechanism the rectilinear motion of the piston rod of cylinder to be converted into the ballistic motion of drift, and simple in structure, cost is low.

Further, the cylinder gauge tap is arranged on fixture substrate, clamping, punch operation conveniently do not need operating personnel to walk up and down.

Description of drawings

Next in connection with accompanying drawing, specific embodiment of the utility model is described in further detail, wherein:

Fig. 1 is the top view of embodiment of the present utility model;

Fig. 2 is the punch mechanism front view of embodiment of the present utility model.

Mark in upper figure: fixture substrate 1, clamp mechanism 2, punch mechanism 3, gauge tap 4, air pipe interface 31, cylinder 32, piston rod 33, supporting seat 34, crank mechanism 35, drift 36, die 37, pulp-collecting box 38.

The specific embodiment

With reference to figure 1, fixture substrate 1 is dull and stereotyped, and clamp mechanism (such as clamp etc.) 2 and punch mechanism 3 are arranged on fixture substrate 1.When the workpiece such as vehicle side or top cover need to clamp rear welding, punching, clamp height take fixture substrate 1 as the benchmark adjustment, make the corresponding welding torch position of weld locations on workpiece, the height of Workpiece clamping position and punch mechanism 3 is adjusted in the left and right take fixture substrate 1 as benchmark again, welds, clamping and punching position meet the requirements simultaneously.

With reference to figure 2, perforating press 3 is pneumatic form, cylinder 32 is fixed on supporting seat 34 tops, crank mechanism 35 pins are connected on supporting seat 34, one end connects the piston rod 33 of cylinder 32, the other end connects drift 36, and die 37 is fixed on position corresponding with drift 36 on supporting seat 34, and when making punching, drift 36 can coordinate with die 37.Below die 37, pulp-collecting box 38 is installed on supporting seat 34, be used for holding the clout under stamping-out.In conjunction with Fig. 1, the gauge tap 4 of cylinder 32 is arranged on fixture substrate 1, and is easy to operate.

After clamp mechanism 2 clamping work pieces and capturing position, operation-control switch 4, compressed air enters cylinder 32 through air pipe interface 31, and pushing piston bar 33 drives crank mechanism 35 rotations, completes punching thereby drift 36 coordinates with die 37.Then, reversal valve is with the counter-rotating of the gas circuit in air pipe interface 31, and piston rod 33 retractions drive crank mechanism 35 counter-rotatings, and drift unclamps.

Although the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and only be subjected to the restriction of claim, those of ordinary skills can easily carry out equivalence to it and replace and modification, but do not leave essence design of the present utility model and scope.
