Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below.

As shown in fig. 1 to 4, a positioning and clamping tool for a peeling machine includes a clamp base 1, a clamp main shaft 10 capable of rotating around the clamp base 1 is provided on the clamp base 1, a mandrel 11 capable of synchronously rotating along with the clamp main shaft 10 is provided inside the clamp main shaft 10, an elastic clamping device is installed on the mandrel 11, and the positioning and clamping tool further includes a push-pull cylinder 7 connected to the clamp base 1 and used for controlling the mandrel 11 to move along its own axis direction. The push-pull cylinder 7 pulls or pushes the mandrel 11 to synchronously drive the elastic clamping device to move along the axial direction of the mandrel 11, so that the switching between the clamping and the loosening actions is realized.

The fixture main shaft 10 is installed on the fixture seat 1 through a tapered roller bearing 2.

The shown elastic clamping means comprise several pairs of jaws 12 mounted on the mandrel 11 at the end remote from the push-pull cylinder 7, between which pairs of jaws 12 springs 14 are connected.

The mandrel 11 is provided with a positioning guide post 15 for guiding the movement of the clamping jaw 12.

The clamp main shaft 10 is provided with a sealing cover 13 for sealing the core shaft 11.

The inner wall of the sealing cover 13 is provided with a wedge-shaped table surface 13a capable of compressing and furling the clamping jaw 12, and the sealing cover 13 is provided with a hole 13b for extending the clamping jaw 12.

The clamping jaw 12 is provided with a sliding groove 12a which is used for sliding fit with the positioning guide post 15.

The output shaft of the push-pull cylinder 7 is provided with a T-shaped slot drawing block 8, and the mandrel 11 is provided with a T-shaped connecting screw rod 9 which is clamped in the T-shaped slot drawing block 8 and can rotate around the T-shaped slot drawing block 8. When the clamp main shaft 10 is driven by external force, the mandrel 11 can be synchronously driven to rotate, and the T-shaped pull groove block 8 and the T-shaped connecting screw rod 9 are matched, so that the push-pull cylinder 7 cannot be influenced in the rotating process of the mandrel 11.

An end-toothed disc positioning block 3 is mounted on the clamp seat 1, a sliding guide post 16 is mounted on the end-toothed disc positioning block 3, an end-toothed disc locking block 4 is mounted on the sliding guide post 16, a support column 5 is mounted on the end-toothed disc locking block 4, and a bearing plate 6 for fixing a push-pull cylinder 7 is mounted on the support column 5.

The push-pull cylinder 7 is a cylinder or an oil cylinder.

The invention can realize the clamping and the loosening of the workpiece by pulling or pushing the mandrel 11 by the aid of the single push-pull cylinder 7 so as to drive the clamping jaws 12.

Before processing, each workpiece to be processed is sequentially arranged on the corresponding fixture main shaft 10, and the elastic force of the spring 14 is utilized to enable the workpiece to be clamped and positioned by the clamping jaw 12, so that peeling processing can be carried out through external equipment.

After the angle positions of all the workpieces are processed, the push-pull cylinder 7 is started to push the mandrel 11, so that the clamping jaws 12 compress the springs 14 inwards under the action of the wedge-shaped table top 13a, the workpieces can be disengaged from the clamping jaws 12, and the workpieces can be conveniently taken down.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
