Description

Positioning and clamping mechanism

Technical Field

The utility model relates to a cutting device technical field particularly, relates to a positioning and clamping mechanism.

Background

Because of its wide material source and excellent plasticity, its kind and application range are more and more extensive, and its processing technology is more and more emphasized. In the traditional processing technology, a casting workpiece needs to be cut, polished and the like to form a qualified product.

At present, a common cutting machine is mainly used for cutting in a subsequent cutting section of a workpiece in a factory; the whole set of working sequence is as follows:

1) an operator places the workpiece on the cutting platform and clamps the workpiece manually or by using a pneumatic clamping plate;

2) an operator adjusts the workpiece to a cutting position and starts the cutting machine;

3) and manually controlling a handle of the cutting machine to cut the workpiece.

The following problems mainly exist in the mechanism:

1) the size of the cutting workpiece is limited due to the fact that the cutting workpiece tool is not adjustable.

2) In the cutting process, the workpiece can be damaged due to the error of the clamping mechanism, and the qualification rate is reduced.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model provides a positioning and clamping mechanism, its specific scheme is as follows:

a positioning and clamping mechanism comprises a machine base, an upper clamping plate 1 and a lower clamping plate 5 which are arranged on the machine base, wherein,

the upper and lower clamping plates 5 are fixedly arranged on the base, the upper clamping plate 1 is arranged on a guide rail arranged on the base and can move along the guide rail, and the precision casting die head 3 is clamped between the upper clamping plate 1 and the lower clamping plate 5;

a plurality of bulges 2 are arranged on the outer side of the fine casting die head 3;

the upper clamping plate 1 is provided with a groove 4 corresponding to the bulge 2 for clamping and positioning.

In a preferable scheme, the protrusion 2 and the groove 4 are both in a conical structure.

Further, a groove 4 corresponding to the protrusion 2 is arranged on the lower clamping plate 5 for clamping and positioning. In a preferable scheme, the protrusion 2 and the groove 4 are both in a conical structure.

The utility model has the advantages of that:

the cutting workpiece of the utility model is clamped by the clamping mechanism, the position is adjustable, and the size range of the workpiece is wide; the clamping part adopts a structure of a bulge and a groove, the clamping effect is good, the stability is high, and the service life of the clamping part is long.

Drawings

Fig. 1 is a schematic structural diagram of a positioning and clamping mechanism of the present invention.

Reference numbers in the figures:

the device comprises an upper clamping plate 1, a protrusion 2, a precision casting mold head 3, a groove 4 and a lower clamping plate 5.

Drawings

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the positioning and clamping mechanism comprises a base, an upper clamping plate 1 and a lower clamping plate 5 which are arranged on the base, wherein the upper clamping plate 5 and the lower clamping plate 5 are fixedly arranged on the base, the upper clamping plate 1 is arranged on a guide rail arranged on the base and can move along the guide rail, a precision casting die head 3 is clamped between the upper clamping plate 1 and the lower clamping plate 5, and the precision casting die head 3 is used for cutting a workpiece to be machined after the workpiece is fixed for a certain time.

The utility model discloses an in the innovation establishes, the precision casting mould head 3 outside is provided with a plurality of archs 2, is provided with the recess 4 corresponding with arch 2 on the last grip block 1 for press from both sides tight location.

In an optimal selection scheme, protruding 2, recess 4 are the toper structure, and the toper structure uses the material more sparingly, and the clamping-force degree is big, and stability is high.

In order to further improve the clamping stability, the lower clamping plate 5 is provided with a groove 4 corresponding to the protrusion 2, particularly, the protrusion 2 and the groove 4 are both in a conical structure, so that the clamping effect is good, the stability is high, and the service life of the clamping part is long.
