The tool rest is simple in structure and convenient to use, and the bolt screwing force is visually displayed, so that the positions of the tool rest before and after installation are basically consistent, and the situation that the bolt is difficult to disassemble or the bolt hole is damaged due to overlarge screwing force is avoided.
Description
Technical Field
The utility model relates to the field of machinery, in particular to a detachable tool rest for a machine tool.
Background
In order to facilitate the maintenance, replacement, etc. of the machine tool, many machine tools are provided with a detachable tool holder, such as a detachable tool holder for a numerical control machine disclosed in patent CN 203817412U. But are typically secured by a plurality of bolts when the tool holder is reinstalled after removal. However, the tightening force of each bolt may vary, which may cause deviation and angular deflection when the tool holder is fixed, and also may cause difficulty in detaching the bolt due to too close rotation when the bolt is rotated, or may cause damage to the screw hole, and thus, improvement is required.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a detachable tool rest for a machine tool. The tool rest is simple in structure and convenient to use, and the bolt turning force is visually displayed, so that the positions of the tool rest before and after installation are basically consistent, and the condition that the bolt is difficult to disassemble or the bolt hole is damaged due to overlarge turning force can be avoided.
The purpose of the utility model is realized by the following technical scheme:
a detachable tool rest for a machine tool comprises a base, wherein a vertical plate is fixed on the base and is fixedly connected with a tool rest body through a plurality of first bolts; a long hole matched with the indication mark is formed in the side wall of the annular sleeve, and scales are marked on one side of the long hole; the inner side of the elastic structure is provided with an annular cushion block.
The elastic structure is an elastic sheet with a W-shaped axial section, the elastic sheet is annular, a plane part is formed in the middle of the elastic sheet, and a through hole matched with the first bolt is formed in the plane part; the periphery of the elastic sheet is formed with a plane ring, and the indication mark is connected with the plane ring.
In a further improvement, the outer diameter of the annular cushion block is smaller than the inner diameter of the annular sleeve.
In a further refinement, the indication is identified as a conical block.
In a further improvement, the tool rest body is U-shaped, and a threaded hole matched with the first bolt is formed in one side of the tool rest body.
In a further improvement, a second bolt for fixing a cutter is connected to the other side of the tool rest body in a threaded manner.
The utility model has the beneficial effects that:
the tool rest is simple in structure and convenient to use, and the bolt screwing force is visually displayed, so that the positions of the tool rest before and after installation are basically consistent, and the situation that the bolt is difficult to disassemble or the bolt hole is damaged due to overlarge screwing force is avoided.
Drawings
The utility model is further illustrated by means of the attached drawings, the content of which is not in any way limitative of the utility model.
Fig. 1 is a schematic view of the overall structure of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and examples.
Example 1
The purpose of the utility model as shown in fig. 1 is realized by the following technical scheme:
a detachable tool rest for a machine tool comprises a base 1, wherein a vertical plate 2 is fixed on the base 1, the vertical plate 2 is fixedly connected with a tool rest body 13 through a plurality of first bolts 3, a pressure indicating structure is installed between the first bolts 3 and the vertical plate 2, the pressure indicating structure comprises an annular gasket 4 adjacent to the first bolts 3, an annular sleeve 7 is fixed on the periphery of the annular gasket 4, an elastic structure 5 is installed on the inner side of the annular gasket 4, an indicating mark 6 is connected onto the elastic structure 5, and the elastic structure 5 is located in the annular sleeve 7; a long hole 8 matched with the indication mark 6 is formed in the side wall of the annular sleeve 7, and scales are marked on one side of the long hole 8; inside the elastic structure 5 is mounted an annular cushion 12.
The elastic structure 5 is an elastic sheet with a W-shaped axial section, the elastic sheet is annular as a whole, a plane part 9 is formed in the middle of the elastic sheet, and a through hole 10 matched with the first bolt 3 is formed in the plane part 9; the periphery of the elastic sheet is formed with a plane ring 11, and the indication mark 6 is connected with the plane ring 11.
The outer diameter of the annular spacer 12 is smaller than the inner diameter of the annular sleeve 7.
The indicator 6 is a conical block.
The tool holder body 13 is U-shaped, and a threaded hole 12 matched with the first bolt 3 is formed in one side of the tool holder body 13.
The other side of the tool holder body 13 is connected with a second bolt 14 for fixing the tool in a threaded manner.
In the utility model, when the tool rest body 13 is disassembled, the scales indicated by the corresponding indication marks 6 on the first bolt 3 are recorded. When the tool rest body 13 is installed, the first bolt 3 is rotated, the first bolt 3 compresses the annular gasket 4 inwards, the annular gasket 4 compresses the W-shaped elastic sheet inwards, the indication mark 6 and the long hole 8 on the W-shaped elastic sheet slide until the position before disassembly is reached, and the first bolt 3 stops rotating. The W-shaped elastic sheet is a metal elastic sheet, so that a large elastic force can be provided in a short stroke, and bolt fastening is facilitated.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the protection scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
