Description

A kind of work holder of internal thread spline broaching

Technical field

The utility model relates to a kind of work holder, relates in particular to a kind of work holder of internal thread spline broaching.

Background technology

The internal thread spline workpiece must position and clamp in the broaching process, and existing clamping mode adopts hydraulic compression or hand-operated clamping usually, and a whole set of clamp structure is complicated, takes up room large, and clamping time is long, and inefficiency also easily crushes workpiece.

The utility model content

The utility model is in order to solve defective and the deficiency that exists in above-mentioned prior art, provide a kind of simple in structure, easy to operate, and part replacement is convenient, thereby reduces operator's labour intensity and difficulty, the work holder of the internal thread spline of increasing work efficiency broaching.

The technical solution of the utility model: a kind of work holder of internal thread spline broaching, comprise clamp body, collet and drive unit, be provided with some bearings of rotating shaft and cooperation rotating shaft in described clamp body, geometrical clamp headgear in described rotating shaft, described collet is arranged in the chuck cover, and described drive unit is arranged on the rotating shaft periphery.

Preferably, the quantity of described bearing is two, is respectively clutch shaft bearing and the second bearing.

Preferably, in described collet, broaching tool is set, workpiece is placed between collet and broaching tool.

Preferably, described clamp body inwall is provided with the step that coordinates clutch shaft bearing and the second bearing.

The utlity model has following advantage: reliable to Workpiece clamping, work-handling is convenient and swift, fixture parts disassembling, assembling and replacing fast and easy, and minimizing operator's labour intensity and difficulty are increased work efficiency.

Description of drawings

Fig. 1 is the schematic diagram under the utility model installment state.

1. broaching tool; 2. workpiece; 3. collet; 4. chuck cover; 5. rotating shaft; 6. drive unit; 7. clutch shaft bearing, 8. the second bearing; 9. clamp body.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, a kind of work holder of internal thread spline broaching comprises clamp body 9, collet 3 and drive unit 6, is provided with two bearings of rotating shaft 5 and cooperation rotating shaft 5 in clamp body 9, is respectively clutch shaft bearing 7 and the second bearing 8.Geometrical clamp headgear 4 in rotating shaft 5, collet 3 are arranged in chuck cover 4, and drive unit 6 is arranged on rotating shaft 5 peripheries.The interior broaching tool 1 that arranges of collet 3, workpiece 2 is placed between collet 3 and broaching tool 1.Clamp body 9 inwalls are provided with the step that coordinates clutch shaft bearing 7 and the second bearing 8.

Operation principle of the present utility model:

Workpiece 2 is positioned in collet 3, and is positioned over together in chuck cover 4, chuck cover 4 is fixed in rotating shaft 5.The descending drive workpiece 2 of broaching tool 1 and collet 3 are descending makes collet 3 inwardly hold workpiece tightly with chuck cover 4 by the conical surface, rotating shaft 5 drives 4 rotations of chuck cover by drive unit 6, clutch shaft bearing 7 and the second bearing 8 etc., and then the drive workpiece rotating, complete the broaching of helical spline.

The utility model is reliable to Workpiece clamping, and work-handling is convenient and swift, fixture parts disassembling, assembling and replacing fast and easy, and minimizing operator's labour intensity and difficulty are increased work efficiency.

Above-described is only preferred embodiment of the present utility model; should be understood that; for those of ordinary skill in the art; under the prerequisite that does not break away from core technology feature of the present invention; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
