Description

A row insert fixture

technical field

The utility model relates to a workpiece clamping device, in particular to a row-position insert clamp used for CNC and EDM processing.

Background technique

The row insert is one of the important components of the row. It is located at the front end of the row and is combined with the core and cavity of the mold to form the complex external shape and structure of the product. Therefore, there is a high requirement for the processing accuracy of row inserts, which generally need to be processed by CNC and EDM. At present, when performing CNC and EDM processing on row inserts, it needs to be clamped and positioned twice on the processing machine directly, which affects the processing efficiency, and there may be deviations between the two positionings, which affects the processing accuracy.

Utility model content

The utility model aims at overcoming the disadvantages of the prior art, and provides a row insert fixture, which enables the row insert to be processed by CNC and EDM only once for clamping and positioning.

In order to achieve the above object, the utility model adopts the following technical solutions:

A row insert fixture includes a fixture main body, a connecting plate and a fixing block. The connecting plate is fixedly connected to the upper fixture main body and the lower fixing block respectively by screws, and the fixing block is a standard part.

The clamp body includes a chuck seat, and a right-angled trapezoidal groove is opened on the upper part of the chuck seat. The trapezoidal groove includes a horizontal bottom surface, a vertical side surface and an oblique side surface, and the oblique side surface forms an obtuse angle with the horizontal bottom surface. A row of inserts is placed in the groove, and the row inserts are close to the vertical side. The clamp body also includes a compression block with a right-angled trapezoidal cross section. The oblique side is matched and connected with the clamp seat through two screws, and the clamp body also includes a cuboid spacer, and the spacer is clamped between the row insert and the pressing block.

The pressing block is provided with two elliptical screw grooves, the screws in the elliptical screw grooves are tightened and loosened, and the pressing block can slide up and down along the inclined side of the trapezoidal groove of the chuck seat.

Beneficial effects of the utility model: the utility model is used for CNC and EDM processing row inserts, which can avoid repositioning and clamping row inserts when the two processing methods are replaced, has a high degree of automation, and can reduce clamping deviations. Reduce labor intensity and improve work efficiency. In addition, the utility model has the advantages of simple structure, easy installation and disassembly, and low manufacturing cost.

Description of drawings

Fig. 1 is a schematic diagram of a three-dimensional structure of a preferred embodiment of the present invention.

Detailed ways

A preferred embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, a row position insert fixture includes a fixture body 1, a connecting plate 2 and a fixing block 3, the connecting plate 2 is fixedly connected to the upper fixture body 1 and the lower fixing block 3 by screws respectively, and the fixing block 3 is a standard part, which is used in conjunction with a standard machine tool fixture (not shown) to realize quick clamping of the row insert fixture. The row insert 4 only needs to be positioned on the row fixture once, and the CNC and EDM processing eliminates positioning errors caused by clamping and positioning row inserts 4 before CNC and EDM processing.

The clamp body 1 includes a chuck seat 11, and a right-angled trapezoidal groove 111 is provided on the upper part of the chuck seat 11. The trapezoidal groove 111 includes a horizontal bottom surface, a vertical side surface and an oblique side surface, and the oblique side surface and the horizontal bottom surface form an obtuse angle. The insert 4, the row insert 4 is close to the vertical side, which is used as a positioning reference plane for the row insert 4, and the clamp body 1 also includes a compression block 12 with a right-angled trapezoidal cross section, the compression block The inclined surface of 12 matches the oblique side of the trapezoidal groove 111 and is connected with the clamp seat 11 by two screws. The clamp body 1 also includes a cuboid pad 13, which is clamped between the row insert 4 and the pressing block 12. During the installation process, the spacer 13 and the compression block 12 are placed in the trapezoidal groove 111 in parallel, and the compression block 12 is fixed with screws. , the row position insert 4 is compressed between the right-angle side of the trapezoidal groove 111 and the spacer 13 . Two elliptical screw grooves 121 are provided on the pressing block 12, and the screws in the elliptical screw grooves are tightened and loosened, and the pressing block can slide up and down along the oblique side of the trapezoidal groove 111 of the clamp seat, so that the row The bit insert 4 is pressed between the vertical surface of the trapezoidal groove 111 of the chuck seat and the spacer 13 . The row-position insert fixture of the utility model has a simple structure and is easy to manufacture, and the use of the row-position insert fixture of the utility model improves processing efficiency, reduces labor intensity of workers, and greatly improves product quality.

The above is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent changes or substitutions made within the substantive scope of the utility model may be directly or indirectly applied to other related technologies fields, all belong to the protection category of the utility model patent.
