Description

Milling machine fixture

Technical Field

The utility model relates to an anchor clamps especially relate to a milling machine fixture.

Background

With the development of manufacturing industry, higher requirements are placed on the machining efficiency and precision of parts, and in the currently applied milling machine fixture, shaft parts are difficult to clamp, and when other parts are used for milling the whole upper surface, clamping needs to be performed twice, so that a large error is likely to be generated, and the machining precision is obviously reduced.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a milling machine fixture.

In order to achieve the purpose, the technical scheme of the utility model as follows, a milling machine fixture, its characterized in that, left and right sides symmetry sets up, including bottom plate, right clamping piece, dog, left clamping piece, guide rail, ejector pin, bolt, the guide rail is fixed to be set up on the bottom plate, left side clamping piece sets up on the guide rail, the dog welding is in the intermediate position of guide rail side, the left side of left side clamping piece is equipped with one the ejector pin, the rear portion of left side clamping piece and the head of ejector pin all is equipped with a unidimensional through-hole, uses the bolt will left side clamping piece with the ejector pin is connected.

Preferably, the bottom notches of the left and right clamp pieces are shaped to conform to the shape of the guide rail.

The utility model discloses following beneficial effect has:

the utility model provides a pair of milling machine fixture, the range of application is wider, can carry out the clamping to the part of different shape size, for example during clamping ladder axle class part, can realize the clamping of two different diameters departments. When the upper surface is milled, the side surface of the part is clamped, so that the whole upper surface can be milled at one time during milling, and the machining error caused by twice clamping is avoided.

Drawings

In order to clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below.

Fig. 1 is a schematic structural view of a milling machine fixture of the present invention;

FIG. 2 is a schematic view of the position of the stopper according to the present invention;

FIG. 3 is a schematic view of a right clamping member of the present invention;

FIG. 4 is a schematic view of the ejector pin of the present invention;

in the figure: the device comprises a base plate 1, a right clamping piece 2, a stop block 3, a left clamping piece 4, a guide rail 5, a push rod 6 and a bolt 7.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described and discussed below with reference to the drawings in the present invention, and it is obvious that only some examples, not all examples, of the present invention are described here, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

Referring to fig. 1, a milling machine fixture comprises a bottom plate 1, a right clamping piece 2, a stop block 3, a left clamping piece 4, a guide rail 5, a mandril 6 and a bolt 7.

Referring to fig. 2, fig. 2 is a schematic view of the stopper 3 in fig. 1.

The stop 3 is welded at the middle position of the side edge of the guide rail 5, and the main purpose is to ensure that the left clamping piece 4 only moves on the left side of the guide rail 5, and the right clamping piece 2 only moves on the right side of the guide rail 5.

Referring to fig. 3, fig. 3 is a schematic view of the right clamping member 2 of fig. 1.

The left clamp 4 is rearward toward the left, and the right clamp 2 is rearward toward the right. The bottom notches of the left clamping piece 4 and the right clamping piece 2 are in the same shape as the guide rail 5.

Referring to fig. 4, fig. 4 is a schematic view of the operation of the lift pin 6 in fig. 1.

The ejector rod 6 can rotate around the bolt 7, and after the parts are placed, the ejector rod 6 is rotated to enable the tail portion of the ejector rod 6 to be clamped in the bulge in the middle of the guide rail 5, so that the movement of the left clamping piece 4 and the right clamping piece 2 is limited, and the parts are clamped. After the machining is finished, the ejector rod 6 is rotated, the tail portion of the ejector rod is moved out of the bulge, the left clamping piece 4 and the right clamping piece 2 can be moved, and the machined part is taken down.

To sum up, it is visible, the utility model relates to a milling machine fixture can realize the clamping to different shape size parts through the position of chooseing for use different guide rails and control left clamping piece and right clamping piece, and application scope is wider, avoids the secondary clamping, has improved the machining precision.
