Problems solved by technology

[0004]In the prior art, in order to ensure the stability of the tool holder, the hydraulic cylinder is installed in the cavity surrounded by the cutter head, the base and the connecting plate , and the structure of the hydraulic cylinder is not an independent component. Its hydraulic chamber is formed by the cooperation of the cylinder body and the base. In this way, the cylinder body and the base will be disassembled during the disassembly and maintenance of the tool holder, resulting in the leakage of the hydraulic oil. leakage, causing waste and pollution of hydraulic oil, which is not conducive to disassembly and maintenance

Embodiment 1

[0040] Such as figure 1 As shown, the vertical lathe includes a bed 16 with a column on which a carriage assembly is installed, and the carriage assembly is connected with a spindle fixture. A tool holder is fixed on one side of the column on the bed 16, and a chip removal hole is provided on the bed 16 below the tool holder. One side of the knife rest is fixedly connected with the column, and the other side of the knife rest is fixed with a chip guide plate, and a support is fixed on the chip guide plate, and the support is fixed on the bed 16.

[0041] Such as Figure 2-Figure 6 As shown, a knife holder includes a base 1, a rotatable connecting seat 2 is installed on the base 1, and a locking member 3 for locking the two is arranged between the connecting seat 2 and the base 1, and the locking member 3 A hydraulic cylinder 4 capable of driving the locking member 3 to reciprocate in the axial direction is connected thereto. The base 1 is provided with a mounting groove 1 a...

Embodiment 2

[0054] The positioning structure 5 is different from the first embodiment, and other structures are the same as the first embodiment. The positioning structure 5 includes an axially fixed guide pin 5b and a guide hole 5a provided on the fixed toothed plate 12. The guide pin 5b is fixed on the locking member 3, and the guide pin 5b is inserted into the guide hole 5a and can slide. Alternatively, the positioning structure 5 includes an axially fixed guide pin 5b and a guide hole 5a provided on the locking member 3, the guide pin 5b is fixed on the partition wall 1d, and the guide pin 5b is inserted into the guide hole 5a and can slide.

Abstract

The invention provides a tool rest, and belongs to the technical field of machine tools. The technical problem of how to enable the knife rest to be convenient to disassemble, assemble and maintain while ensuring the working stability is solved. The tool rest comprises a base and a tool bar, a rotatable connecting base used for being fixed to the tool bar is installed on the base, a locking piece for locking the connecting base and the base is arranged between the connecting base and the base, a hydraulic cylinder capable of driving the locking piece to reciprocate in the axial direction is connected to the locking piece, and an installation groove for containing the connecting base and the locking piece is formed in the base. A cylinder body of the hydraulic cylinder is detachably and fixedly connected to the base and located outside the mounting groove, a hydraulic cavity of the hydraulic cylinder is independent of the base, and a positioning structure enabling the locking piece to be circumferentially positioned is further arranged in the mounting groove. The knife rest is convenient to disassemble, assemble and maintain while the working stability is ensured.

Description

technical field [0001] The invention belongs to the technical field of machine tools and relates to a tool rest. Background technique [0002] In the vertical lathe, a column is set on the bed, a carriage assembly is installed on the column, a spindle fixture is installed on the carriage assembly, the workpiece is clamped on the spindle fixture, a tool holder is fixed on the side of the column on the bed, and a tool holder is installed on the tool holder. knives. When the workpiece is processed, the tool does not move, the spindle fixture rotates to drive the workpiece to rotate, and the carriage assembly drives the workpiece to move up, down, left, and right. [0003] With the development of automation, in order to improve the processing efficiency, a rotatable cutter head is installed on the tool holder, several knives are fixed on the cutter head, and the tools are automatically switched according to the processing requirements during the processing. For example, a kind...
