Background

The commonly used scribing tool at present on the lathe is a common turning tool, the removal amount is controlled by a numerical control machine, and the turning tool directly scribes on the surface of a workpiece. For some large thin-wall parts, because stress release can occur in the machining process to generate deformation, when the deformed workpiece is required to be scribed, the depth and the width of the scribed line on the workpiece by a common turning tool are influenced by the deformation of the workpiece, the depth and the width of the scribed line are inconsistent, and the scribing requirement cannot be met. There is a great need for a device for scribing a deformable workpiece. Aiming at the characteristic that the workpiece is easy to deform, the scribing device can adjust the removal amount back and forth according to the deformation of the workpiece, and uniform scribing is realized through the rotation of the lathe turntable. The utility model discloses application range is wider, and processingquality is stable, and efficiency is higher.

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

The utility model discloses a groove device, as shown in fig. 1, including handle of a knife 1, elastic cushion 2, slider 3 and groove cutter 5, the terminal surface of 1 one end of handle of a knife has the blind hole, and elastic cushion 2 and slider 3's one end is movably settled in the blind hole in proper order, and the terminal surface of the other end of slider 3 has the mounting hole, groove cutter 5 one end with the mounting hole cooperation is fixed on slider 3.

The utility model discloses an in the embodiment, according to lathe knife rest size, choose for use the suitable bar preparation handle of a knife 1 of size. The blind hole on the end face of one end of the cutter handle 1 is coaxial with the cutter handle 1, and the other end of the cutter handle 1 is butted with a cutter rest of a machine tool. The resilient pad 2 has good resilience, preferably a spring. The elastic cushion block 2 is arranged in the blind hole, and the free length of the elastic cushion block 2 is smaller than the depth of the blind hole, so that the elastic cushion block 2 can be completely accommodated in the blind hole, and the elastic cushion block 2 can be compressed in the blind hole. The slider 3 is the bar-shaped, and the one end of slider 3 can stretch into in the blind hole and can slide in the blind hole to extrusion elastic cushion 2. When the elastic cushion block 2 is in a compressed state, the other end of the sliding block 3 still exposes out of the blind hole of the tool handle 1. The mounting hole on the end face of the sliding block 3 is an inner hole and is coaxial with the sliding block 3. The side wall of the exposed end of the sliding block 3 is provided with two threaded holes communicated with the mounting hole, and preferably, the number of the threaded holes is two, and the sliding block is provided with screws 4 matched with the threaded holes. Turning the screw 4 so that the screw 4 is against the side wall of the reticle tool extending into the mounting hole portion can be used to secure the reticle tool 5 against rotation.

The utility model discloses an in the implementation row, in order to guarantee the stability of groove device in the course of the work, the shape phase-match and the fit clearance of slider 3 and blind hole are between 0.05mm ~ 0.1mm, and the too big axiality that influences whole device in fit clearance can lead to the deviation to appear in the actual position and the theoretical position of groove, and the clearance undersize can influence the flexible performance of spring. The shapes of the scribing cutter 5 and the mounting hole are matched, the fit clearance is between 0.03mm and 0.05mm, and the accuracy of the scribing position is also influenced by the size of the clearance. The knife handle 1 is made of rigid materials, and sufficient hardness is guaranteed, for example, metal materials such as steel and iron. The line cutting tool 5 is made of hard alloy materials, the line cutting tool 5 is provided with a tool tip, and the tool tip is conical and needs to be sharpened so as to be coaxial with the sliding block 3; the diameter of the tool nose is proper, the tool nose is easy to break after being stressed if the diameter is too small, and materials are wasted if the diameter is too large.

The scribing device of the present invention is embodied as follows:

as shown in fig. 1, a shank 1 of the scribing device is clamped to a tool post of a machine tool, a spring 2 and a slide block 3 are assembled in sequence, and a scribing tool 5 is fixed to the slide block 3 by a screw 4.

And fixing the rotary workpiece needing to be scribed on a machine tool main shaft, and moving the machine tool main shaft to enable the part of the rotary workpiece needing to be scribed to be in contact with the tool tip of the scribing tool 5. The axial speed of the machine tool is controlled to be 40-50m/min, the feed amount is reasonably controlled according to the deformation amount of the selected elastic cushion block 2, and at the moment, the cutter head of the scribing cutter 5 extrudes the surface of the rotary workpiece to scribe lines, and the surface of the deformed workpiece can also be continuously scribed due to the flexibility of the elastic cushion block 2.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
