Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.

Referring to the attached drawings 1-3, the equidistant material puller is provided with a positioning rod 1 fixed with a machine tool moving mechanism, one side of the positioning rod 1 is provided with a material pulling block 2, and the material pulling block 2 is internally provided with a clamping device used for clamping a workpiece 100 and enabling the end part of the workpiece 100 to be tightly attached to the side wall of the material pulling block 2. When the material puller is used, the material puller is integrally clamped on a moving mechanism of a machine tool through the positioning rod 1, the material puller is coaxial with the workpiece 100, the moving mechanism of the machine tool drives the material puller to move along the axial direction of the workpiece 100, and the material puller is pulled at equal intervals under the accurate movement control of the moving mechanism on the material puller. The equidistance processing operation to longer work piece is convenient for, has solved the great problem that leads to very easily causes the waste of work piece waste material of artifical material pulling size error. The clamping device has the function of enabling the end part of the workpiece 100 to be tightly attached to the side wall of the material drawing block 2 when clamping the workpiece, so that the problem of movement error caused by sliding of the clamping device on the workpiece 100 during clamping movement is avoided.

Specifically, clamping device includes the articulated clamping rod 3 that just has bow-shaped column structure of upper and lower symmetry of extract block 2, and every clamping rod 3 all includes the clamping part 31 that is located the extract block 2 outside and the inside atress portion 32 of extract block 2, be equipped with the force applying device that is used for clamping part 31 to hug closely work piece 100 centre gripping on the atress portion 32. During clamping, the force applying device applies force to the force receiving portions 32 of the clamping rods 3 on two sides simultaneously, and the clamping rods 3 rotate integrally along with the pulling block 2, so that the corresponding clamping portions 31 approach to each other and cling to the surface of the workpiece 100 to be clamped. As shown in fig. 2, since the clamping rod 3 is of an arch structure, when the force applying device 3 applies an external force to the force receiving portion 32, the clamping rod 3 rotates around the hinge point, the end of the clamping portion 31 moves in an arc toward the material extracting block 2 (as shown by the arrow in fig. 2), and the moving direction has a clamping force for pressing the workpiece 100 and a friction force toward the material extracting block 2, and the friction force can overcome the relative sliding between the workpiece 100 and the clamping portion 31 under the clamping force, so that the end of the workpiece 100 can be tightly attached to the sidewall of the material extracting block 2 in real time, thereby improving the precision of the material extracting length of the material extracting block 100 at equal intervals, and avoiding the waste of the workpiece 100 during processing.

Specifically, the force applying device is an elastic component which is arranged on the inner side wall of the material pulling block 2 and is abutted against the force receiving part 32. The elastic member is preferably a spring 5, and a support block 6 for supporting the spring 5 is provided on an inner side wall of the dial block 2. The spring 5 acts on the force bearing part 32, so that the end part of the clamping part 31 is pressed on the surface of the workpiece 100, and the end part of the workpiece 100 is driven to be tightly attached to the side wall of the pulling block 2.

Further, in order to solve the problem of the sliding between the workpiece 100 and the clamping rod 3, the end of each clamping portion 31 is hinged with a clamping plate 4, the outer bottom surface of each clamping plate 4 is provided with an inclined surface 401 contacting with the workpiece, and the inclined surfaces 401 incline towards the two sides of the material pulling block 2. The clamping cavity formed by the inclined surfaces of the symmetrical clamping plates 4 is of a conical structure, one side of the smaller opening of the clamping cavity is positioned on one side of the sliding direction of the workpiece 100, and one side of the larger opening has larger friction force, so that the friction force of the small opening on the workpiece 100 is increased along with the sliding of the workpiece 100, the sliding of the workpiece 100 is overcome, the end part of the clamping cavity clings to the side wall of the material drawing block 2 under the action of the spring 5, and the drawing precision is improved.

The principle of the utility model is that: the material pulling device is positioned on a machine tool, and moves accurately through the moving mechanism to pull long workpieces at equal intervals and process the long workpieces for multiple times, so that the problem that waste of workpiece waste is easily caused due to large errors of material pulling sizes in manual operation is solved.
