Description

CNC positioning and processing jig for small pull rod bushing

Technical Field

The utility model belongs to the technical field of the CNC location processing tool, especially, relate to a little pull rod bush CNC location processing tool.

Background

As shown in fig. 2, the small pull rod parts mainly comprise a small shaft section 11 and a large shaft section 12, the small shaft section is a round shaft, the large shaft section is a special-shaped shaft with a plane side wall part, and an inner groove 13 with the same cross-sectional shape as the large shaft section is arranged on the end surface of the large shaft section.

In CNC positioning machining of the small pull rod, a milling machine vice is generally adopted for clamping, wherein each machining time is one, a usage meter is required to be swept flat, and meanwhile, repeated centering is required to be carried out on a workpiece; however, since the workpiece has a small size and a special-shaped shaft structure, it is inconvenient for reference and difficult to clamp, and it is easy to shift during machining, resulting in an out-of-position.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an overcome the not enough of prior art, provide a make things convenient for clamping location, guarantee processingquality's little pull rod bush CNC location processing tool.

In order to realize the purpose, the utility model adopts the following technical scheme: the utility model provides a little pull rod bush CNC location processing tool, include the tool main part with install in the repeated location external member of tool main part bottom, set up a plurality of clamping holes that are used for holding the work piece in the tool main part, the clamping hole is the shoulder hole, and it includes the little shaft section male hole of stepping down and the big shaft section male dysmorphism hole of supplying the work piece, wear to establish the fixed screw spare that is used for fixed work piece on one side pore wall in dysmorphism hole.

Preferably, the clamping holes are symmetrically provided with two rows, and the clamping holes in each row are uniformly arranged at intervals along the length direction of the jig main body.

Preferably, fabrication holes are formed at corners of the side walls of the special-shaped holes.

Preferably, the depth of the profiled bore is less than the height of the major axial section of the workpiece.

Preferably, the relocation kit is comprised of an EROWA relocation kit.

The technical effects of the utility model are that: the machine tool is utilized to simultaneously pre-position and clamp a plurality of workpieces, and the repeated clamping and positioning of the fixed position of the tool is carried out by utilizing the repeated positioning external member, so that the time for machine halt clamping is effectively saved, the clamping efficiency is improved, the clamping error is reduced, the machine utilization rate is improved, and the processing quality of the workpieces is ensured.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is an explosion diagram of the present invention.

The reference numerals of the main technical features in the figure are as follows: 11. a small shaft section; 12. a large shaft section; 13. an inner tank; 2. a jig main body; 3. a repeat location kit; 4. clamping holes; 41. a profiled hole; 42. a fabrication hole; 43. and (4) screws.

Detailed Description

The invention will be further explained by means of the following description and the attached drawings.

As shown in fig. 1 to 2, a CNC positioning and processing jig for a small pull rod bushing comprises a jig main body 2 and a repeated positioning kit 3, wherein the repeated positioning kit 3 is an EROWA repeated positioning kit and is composed of an EROWA positioning sheet, an outer hexagon bolt and a clamping rivet, and the repeated positioning kit 3 can be positioned and installed at the bottom of the jig main body 2 through the outer hexagon bolt and the clamping rivet.

Further, two rows of clamping holes 4 are formed in the jig main body 2, each row of clamping holes 4 is formed along the length direction of the jig main body 2, a plurality of clamping holes are formed in the length direction of the jig main body, the direction of each clamping hole is the same, and the two rows of clamping holes 4 are symmetrically arranged.

Specifically, clamping hole 4 is the shoulder hole, and it includes dysmorphism hole 41 and the hole of stepping down, and the hole of stepping down is seted up in the bottom of dysmorphism hole 41 and for the round hole, dysmorphism hole 41 is for stepping down the hole with the similar class of cross-section appearance of work piece major axis section 12, and its lateral wall comprises plane and cambered surface joint, and the junction of plane and cambered surface has seted up fabrication hole 42, because the volume of little pull rod is less, therefore the aperture in this dysmorphism hole is also less, and the processing that can make things convenient for dysmorphism hole 41 of seting up of this fabrication hole moves back the sword and auxiliary workpiece takes.

Further, the depth of the profiled hole 41 is smaller than the height of the large shaft section 12 of the workpiece.

Further, a screw hole is formed in the arc-shaped side wall of the special-shaped hole 41, and a screw 43 is matched with the inner thread of the screw hole to press the workpiece.

The utility model discloses a concrete implementation process as follows: when the jig clamps a workpiece, the small shaft end of the workpiece is inserted into the abdicating hole, the small shaft end of the workpiece is in transition fit with the special-shaped hole 41, then the workpiece is compressed through the screw 43, and the jig is clamped to a fixed position by utilizing the repeated positioning kit 3 so as to process the workpiece in batches.

The above description is only the specific embodiments of the present invention, but the structural features of the present invention are not limited thereto, the present invention can be used in similar products, and any person skilled in the art can be in the field of the present invention, and all the changes or modifications made are covered in the scope of the present invention.
