Description

Can support hand claw of pay-off

Technical Field

The utility model belongs to the technical field of machinery, a can support the hand claw of pay-off is related to, especially relate to a can support the hand claw of pay-off to long shaft class work piece.

Background

The manipulator is an automatic device with the function of grabbing and moving workpieces, which is used in the automatic production process, is a novel device developed in the mechanical and automatic production process, can simulate certain actions of hands and arms of a person, is used for replacing manual heavy labor, and improves the production automation level and the work efficiency.

At present, the loading and unloading modes of long-shaft workpieces mainly comprise two modes: one is a tool for supporting long-shaft workpieces, and the tool is installed in a numerical control lathe, but the tool is easily adhered or wound by scrap iron in the machining process, so that the subsequent positioning of the long-shaft workpieces is influenced; the other mode is that the workpiece is gripped by the paw of the manipulator, the workpiece is propped by the tailstock, and the paw is loosened, however, in the process that the workpiece is propped by the tailstock, the workpiece is gripped by the paw all the time, the axial movement acting force is inevitably applied to the workpiece by the tailstock, and great abrasion is caused to the paw gripping the workpiece, so that the service life of the paw is greatly reduced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the above-mentioned problem that prior art exists, provide a can support the hand claw of pay-off, influence life's problem when having solved current hand claw and carrying long shaft class work piece.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides a can support hand claw of pay-off, includes the hand claw seat, be connected with on the hand claw seat and drive actuating cylinder and be provided with relatively and indicate one and indicate two, its characterized in that, indicate the quantity of one and indicate two the same and be at least two, indicate one and indicate two one-to-one ground and set up relatively, the several point one sets up side by side and all fixes on the hand claw seat, drive actuating cylinder can drive the several point two are close to respectively or keep away from point one, point one orientation point one side of two has recessed support mouth.

When the gripper capable of supporting feeding grabs a long-shaft workpiece, the driving cylinder drives the two fingers to be away from the first finger, the clamping opening is opened, and after the workpiece is placed in the clamping opening, the two fingers are close to the first finger to clamp the workpiece. When the workpiece is moved to the front of the tailstock, the driving cylinder drives the plurality of fingers two to be away from the fingers one again, so that the long-axis workpiece falls into the support ports of the fingers one arranged in parallel to provide support for the long-axis workpiece, then the tailstock is abutted against the workpiece, and the paw is withdrawn. In the process, the claw capable of supporting feeding can achieve the function of grabbing workpieces, and can support long-shaft workpieces by means of the support openings on the fixed fingers after feeding, so that the claw cannot be excessively abraded when the tailstock leans against the tail seat, and the service life of the claw is guaranteed.

In the above-mentioned claw capable of supporting and feeding, the plurality of fingers two are connected into a whole and can be synchronously close to the plurality of fingers one when being driven by the driving cylinder.

In the above-mentioned feed supporting gripper, a side of the second finger facing the first finger has a concave recess.

As another situation, in the above-mentioned gripper capable of supporting feeding, the number of the driving cylinders is the same as that of the second fingers, and the driving cylinders are arranged in a one-to-one correspondence manner.

In the above-mentioned claw capable of supporting and feeding, the driving cylinder, the first finger and the second finger are fixed on the top and the side of the claw seat.

Compared with the prior art, the gripper capable of supporting feeding can achieve the function of grabbing workpieces, and can support long-axis workpieces by means of the support openings on the fixed fingers after feeding, so that the gripper cannot be excessively abraded when the tailstock leans against the tailstock, and the service life of the gripper is guaranteed.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Example one

As shown in figures 1 and 2, the claw capable of supporting and feeding comprises a claw seat 1, wherein a driving cylinder 2 and a first finger 3 and a second finger 4 are oppositely arranged at the top and the side of the claw seat 1. Since the structure of the top connection of the gripper base 1 is the same as the structure of the side connection of the gripper base 1, the structure of the side of the gripper base 1 will be specifically described below as an example.

The number of the first fingers 3 and the number of the second fingers 4 on the side portion of the claw seat 1 are the same and are at least two, the first fingers 3 and the second fingers 4 are arranged oppositely in a one-to-one correspondence mode, the first fingers 3 are arranged in parallel and are all fixed on the claw seat 1, the driving cylinder 2 can drive the second fingers 4 to be close to or far away from the first fingers 3 respectively, and one side, facing the second fingers 4, of the first fingers 3 is provided with a concave supporting opening 5.

In the embodiment, the number of the first finger 3 and the second finger 4 is two, and if necessary, the number can be increased to three or even four; the two fingers two 4 are connected into a whole and can be synchronously close to the two fingers one 3 when driven by the same driving cylinder 2, and one side of the two fingers 4 facing the finger one 3 is also provided with a concave notch 6 so as to be convenient for clamping a workpiece.

When the gripper capable of supporting feeding grabs a long-shaft workpiece, the driving cylinder 2 at the top of the gripper seat 1 drives the two fingers two 4 to be away from the finger one 3 synchronously, a clamping opening is opened, and after the workpiece is placed in the clamping opening, the two fingers two 4 are close to the finger one 3 and clamp the workpiece.

After the workpiece is clamped, the paw seat 1 is turned over, the workpiece clamped at the top of the paw seat 1 is moved to the side part, the workpiece is moved to the front of the tailstock, the driving cylinder 2 drives the two fingers two 4 away from the finger one 3 again, the long-axis workpiece falls into the supporting ports 5 of the two fingers one 3 arranged in parallel under the action of self gravity, the two fingers one 3 arranged in parallel support the long-axis workpiece, and then the tailstock abuts against the workpiece, and the paw can be withdrawn.

In the claw capable of supporting and feeding, the same structure is arranged at the top and the side of the claw seat 1 at the same time, so that the first finger 3 and the second finger 4 at the top are used for clamping a workpiece, and the first finger 3 and the second finger 4 turned to the side are used for feeding the workpiece before being sent to the tailstock.

Example two

The scheme of this embodiment is substantially the same as that of the first embodiment, except that: the number of the driving cylinders 2 is the same as that of the second fingers 4, and the driving cylinders are arranged in a one-to-one corresponding mode.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
