Abstract

The utility model relates to a positioning fixture with reference for milling machine, which comprises a base which can be installed on the milling machine workbench, wherein the bottom of the base is provided with a reference key which is matched with the milling machine workbench, and the base is also provided with a reference groove which is vertical to the reference key; and the base is also vertically provided with a screw rod which penetrates out of the reference block and is sleeved with a pressing block and a nut. The utility model discloses anchor clamps pass through the base and the reference block on it, and the machined side that can guarantee the work piece is the vertical state with the milling machine arbor by the reference surface that utilizes this reference block and the side of waiting to process the work piece tightly pastes mutually, ensures that this side is still kept perpendicular rather than adjacent face after being processed, guarantees the machining precision promptly, has just so saved the correction time of processing at every turn to improve production efficiency.

Description

A fixture with reference positioning for milling machine

Technical field:

The utility model belongs to the technical field of mechanical equipment, and relates to a milling machine, in particular to a fixture with reference positioning of a milling machine.

Background technique:

Milling machine is a common mechanical equipment. In the process of mold processing, it is necessary to process the cuboid mold frame, etc. For the cut cuboid material, it is necessary to use a milling machine to process each surface. In the process of processing, it is necessary to position and ensure that the adjacent Perpendicularity between faces. On the traditional milling machine workbench, there are generally only two screw clamps for positioning, and there is no reference positioning device. Every time the positioning of the workpiece needs to be manually adjusted by calibration tools, it is very troublesome and affects production efficiency.

Utility model content:

The purpose of the utility model is to overcome the above-mentioned disadvantages of the prior art, and provide a fixture with reference positioning for a milling machine.

The technical solution adopted by the utility model to achieve its purpose is: a milling machine with reference positioning fixture, the positioning fixture includes a base that can be installed on the milling machine workbench, the bottom of the base is provided with the milling machine workbench. A reference key, and the base is also provided with a reference groove perpendicular to the reference key, a reference block is fixed in the reference groove, the reference plane of the reference block is parallel to the milling machine tool axis and perpendicular to the base; There are screw rods and nuts covered with pressing plates.

The base in the fixture of the utility model is positioned in cooperation with the positioning groove of the milling machine worktable through the bottom reference key, and then a vertically arranged reference block is installed in the reference groove on the base, and the reference surface of the reference block is used to match the workpiece to be processed. One side of the workpiece is tightly attached to ensure that the machined side of the workpiece is perpendicular to the milling machine tool axis, ensuring that the side is still perpendicular to the adjacent surface after being machined, that is, the machining accuracy is guaranteed, which saves each machining time. Correction time, thus improving production efficiency.

Description of drawings:

Fig. 1 is a schematic diagram of the structure of the fixture with reference positioning of the utility model;

Detailed ways:

Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described.

As shown in Figure 1, a milling machine with a benchmark positioning fixture described in the utility model, a milling machine with a benchmark positioning fixture, the positioning fixture includes a base 1 that can be installed on the milling machine workbench, the base 1 The bottom of the base is provided with a reference key 11 that matches with the milling machine table, and a reference groove 12 perpendicular to the reference key 11 is also provided on the base 1, and a reference block 2 is fixed in the reference groove 12, and the reference block 2 The surface 21 is parallel to the cutter axis of the milling machine and perpendicular to the base 1 ; the screw 3 and the nut 32 covered with the pressure plate 31 are mounted on the reference block 2 .

The reference block 2 has a cuboid structure, and after being installed in the reference groove 12, it is in a vertical state with the base 1, so that its reference plane 21 is parallel to the milling machine tool axis; several longitudinal through holes 20 are provided on it, and one of the through holes It is used for threading the screw rod 3, and the other through holes are used for threading bolts to fix the reference block 2 on the base 1. When in use, it is only necessary to close one side of the workpiece 4 to be processed against the datum surface 21 of the datum block 2 , and then lock and fix the pressure block 31 on the screw rod 3 through the nut 32 .

The base 1 in the fixture of the utility model is positioned in cooperation with the positioning groove of the milling machine workbench through the bottom reference key 11, and then a vertical reference block 2 is installed in the reference groove 12 on the base 1, and the reference block 2 is utilized The datum surface 21 is tightly attached to one side of the workpiece 4 to be processed to ensure that the processed side of the workpiece is perpendicular to the milling machine tool axis, and to ensure that the side is still perpendicular to the adjacent surface after being processed, that is, to ensure the machining accuracy , which saves the correction time for each processing, thereby improving production efficiency.
