Description

A processing fixture for punching needles of large printers

Technical field:

The utility model relates to the technical field of processing equipment for punching needles of printers, in particular to a processing fixture for punching needles of large printers.

Background technique:

When the existing printer tines are processed in the machining center, they are generally fixed and clamped on the machining center manually, and there is no special fixture for clamping. The surface layer is easily damaged during clamping, and only one can be clamped and processed at a time. ,low efficiency.

Utility model content:

The purpose of this utility model is to provide a processing fixture for punching needles of large printers in view of the deficiencies of the prior art. It can clamp multiple punching needles at one time for processing, and the surface layer of the punching holes is not easy to be damaged during clamping. .

The technical solutions of the present utility model are as follows:

A processing fixture for punching needles of large printers, including a base, on which a plurality of protrusions are formed, and protrusions are formed in the middle of both sides of the protrusions, and the punching needle is clamped between the two protrusions. The sleeve is inserted into the groove of the punching pin; the pressing plate is fixedly connected to the bump through bolts, and the pressing plate is pressed against the punching pin.

Nine rectangular bumps are molded on the base, and a needle hole is clamped between every two bumps. the

Among the nine bumps, screw holes are formed on every other bump.

Fixing screw holes are formed on the base.

The beneficial effects of the utility model are:

1. It clamps the tine between the two protrusions, and the protrusion is inserted into the groove of the tine to ensure that the surface of the tine will not be damaged when it is clamped.

2. It can clamp multiple tines at one time for processing, which improves the efficiency.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the structural representation of the clamping perforating needle of the present utility model;

Fig. 3 is a structural schematic diagram of the punching needle.

In the figure: 1, base; 11, fixing screw hole; 2, bump; 21, protrusion; 22, screw hole; 3, punch; 31, groove; 4, pressure plate. the

Detailed ways:

Embodiment: As shown in Fig. 1 to Fig. 3, a processing jig for large-scale printer perforating pins includes a base 1 on which a plurality of bumps 2 are formed, and protrusions are formed in the middle of both sides of the bumps 2 21. The perforating needle 3 is clamped between the two protrusions 2, and the protrusion 21 is inserted into the groove 31 of the perforating needle 3; the pressure plate 4 is fixedly connected to the protrusion 2 by bolts, and the pressure plate 4 is pressed against the Tine 3 on.

Nine rectangular bumps 2 are molded on the base 1 , and a needle hole 3 is clamped between every two bumps 2 . the

Among the nine bumps 2 , screw holes 22 are formed on every other bump 2 .

A fixing screw hole 11 is formed on the base 1 .

Working principle: Clamp the tine 3 in the two protrusions 2, the protrusion 21 is inserted into the groove 31 of the tine 3, and then the pressure plate 4 is fixedly connected to the protrusion 2 by bolts, the pressure plate 4 Press against tine 3. Install in sequence, a total of 8 tines 3 can be installed in this fixture, and then this fixture is connected to the workpiece clamping table of the machining center by bolts for processing.
