Description

Special thin-walled workpiece clamp for milling machine

Technical Field

The utility model relates to the field of milling machine fixture design, in particular to a thin-wall part fixture special for a milling machine.

Background

The common fixture structure is adopted in the process of machining the thin-wall part by the milling machine, the fixture for the thin-wall rectangular workpiece cannot be clamped in the machining process, and the problems of deformation, inaccurate machining precision and the like of the thin-wall rectangular workpiece usually occur in the process of clamping the thin-wall rectangular workpiece by the milling machine in the process of machining the part, so that the thin-wall rectangular workpiece is further machined and scrapped, and the production efficiency is low.

Disclosure of Invention

The utility model solves the technical problem of overcoming the defect that the existing milling machine clamps a thin-wall rectangular workpiece, provides the thin-wall workpiece clamp special for the milling machine, has simple structure, is practical and convenient, can solve the problem of clamping the thin-wall rectangular workpiece in the milling machine processing process, and can effectively solve the problem in the background technology.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a special thin wall spare anchor clamps of milling machine, is equipped with the briquetting in, the medial extremity of briquetting is fixed with splint, there is corresponding draw-in groove in the splint, the base left side is equipped with the slide bar, the right-hand member of slide bar is fixed with the ejector pad, the left side of base through branch be fixed with electric telescopic handle with the left end of telescopic link is fixed continuously.

As a preferable scheme of the present invention, a backing plate is fixed on an end surface of an outer side of the pressing block, an accommodating groove is provided at a position corresponding to the backing plate, and a plurality of sets of tension springs are fixed between the backing plate and the base.

As a preferable scheme of the utility model, an inner rod is fixed on the right end face of the base, an extension spring is fixed on the outer side face of the inner rod, and the extension spring is fixedly connected with the inner side end of the pressing block.

As a preferred scheme of the utility model, the push block and the clamping plate are internally provided with corresponding clamping grooves which are matched with the clamping plate in the clamping process, so that the final thin-wall rectangular workpiece is clamped.

Compared with the milling machine fixture for the lower thin-wall part, the milling machine fixture has the beneficial effects that: the thin-wall part clamp special for the milling machine is simple in structure and convenient to control, corresponding matching is carried out through the push block and the clamping plate, foundation support is carried out from the inner side of a workpiece, clamping deformation of a thin-wall rectangular workpiece is avoided, pressure is applied from inside to outside, clamping is more stable, shaking of the thin-wall rectangular workpiece in the machining process is avoided, and machining quality of the thin-wall rectangular workpiece is guaranteed.

Drawings

FIG. 1 is a schematic cross-sectional view of the present invention.

In the figure: 1, an electric telescopic rod; 2, a base; 201 accommodating grooves; 202 an extension spring; 203 is fixed with an inner rod; 3, a sliding rod; 4, pushing a block; 5, briquetting; 501 a backing plate is fixed; 502 sets of extension springs; 6, clamping the plate.

Detailed Description

Referring to fig. 1, the present invention provides a technical solution: a thin-wall part clamp special for a milling machine comprises an inner rod 203 fixed on the right end face of a base 2, an extension spring 202 fixed on the side face of the inner rod, and a pressing block 5 fixedly connected with the outer side of the extension spring 202. The clamp for the thin-wall rectangular workpiece is characterized in that a base plate 501 is fixed on the end face of the outer side of a pressing block 5, a containing groove 201 is formed in the corresponding position of the base plate 501, a plurality of groups of extension springs 502 are fixed between the base plate and the base 2, springs are arranged inside and outside the pressing block 5 for the purpose of longitudinally clamping the clamping plate, a clamping plate 6 is fixed at the inner side end of the pressing block 5, a corresponding clamping groove is formed in the clamping plate 6 for the purpose of facilitating installation and clamping of the thin-wall rectangular workpiece, a sliding rod 3 is arranged on the left side of the base 2, a pushing block 4 is fixed at the right end of the sliding rod 3, an electric telescopic rod 1 is fixed on the left side face of the base 2 through a supporting rod and is fixedly connected with the left end of the sliding rod 4, the electric telescopic rod 1 is connected with a power supply through an external control switch, the sliding rod 3 and the pushing block 4 are controlled to move leftwards or rightwards, the clamp for the thin-wall rectangular workpiece is convenient to install and simple to operate, and clamps the thin-wall rectangular workpiece are controlled by the pushing block 4 and the clamping plate 6, the clamping is more stable, the deformation of the thin-wall rectangular workpiece caused when the thin-wall rectangular workpiece is clamped is avoided, the machining quality is ensured, and meanwhile, the push block 4 and the clamping plate 6 can be adjusted, so that the clamping device is suitable for thin-wall rectangular workpieces of different sizes.

In the using process: firstly, the electric telescopic rod 1 is controlled to push a certain distance leftwards, the thin-wall rectangular workpiece is installed at the position of the clamping plate 6, the clamping plate 6 needs to move the clamping plate 6 on one side towards the pressing block 5, then the thin-wall rectangular workpiece is placed at the clamping groove of the clamping plate 6 to be longitudinally clamped, then the electric telescopic rod 1 is controlled to push rightwards, so that the pushing block 4 is matched and clamped on the left side of the thin-wall rectangular workpiece, and finally whether the thin-wall rectangular workpiece is clamped or not is checked.

The clamping device is simple in structure and convenient to operate, ensures the clamping stress uniformity of the thin-wall rectangular workpiece, avoids the damage of the thin-wall rectangular workpiece, and ensures the processing quality of the thin-wall rectangular workpiece.
