Description

Turning tools with special coupling sleeves

technical field

The utility model relates to the technical field of turning tools, in particular to a turning tool with a special coupling sleeve.

Background technique

A turning tool is a tool for turning that has one cutting portion. Turning tool is one of the most widely used tools in cutting. The working part of the turning tool is the part that generates and processes chips, including the cutting edge, the structure that breaks or rolls up the chips, the space for removing or storing chips, and the passage of cutting fluid. The cutting part of the turning tool is composed of the main Cutting edge, auxiliary cutting edge, rake face, main flank and auxiliary flank, and tool nose angle.

The standard turning tool clamping block of the traditional vertical lathe is large in size, and it is impossible to process parts with smaller apertures on the reverse side, and some parts have high concentricity requirements and need to be clamped on the vertical lathe once to complete the processing. If the tool is changed Or change the clamping method, and the concentricity cannot meet the requirements.

Utility model content

The technical problem to be solved by the utility model is: in order to overcome the large volume of the turning tool clamping block of the standard configuration of the traditional vertical lathe in the prior art, it is impossible to process parts with smaller apertures on the reverse side after the workpiece is clamped, and some parts The concentricity requirement of the machine is relatively high, and it needs to be processed on the vertical lathe in one clamping. If the tool is changed or the clamping method is changed, the concentricity cannot meet the requirements. A turning tool with a special coupling sleeve is provided.

The technical solution adopted by the utility model to solve the technical problem is: a turning tool with a special connecting sleeve, including a handle, a connecting sleeve, a turning tool bar and a turning blade, and a pull nail is fixedly installed above the handle. The lower surface of the tool handle is provided with a blind hole, the coupling sleeve is fixedly installed in the blind hole, the lower end of the coupling sleeve is radially opened with a through hole, the turning tool bar is fixedly installed in the through hole, The blade is fixedly mounted on the end of the turning tool holder.

The fixing of the coupling sleeve and the tool handle and the fixing of the turning tool and the coupling sleeve are all fixed by fastening screws. Since the coupling sleeve can slide in the blind hole to adjust the exposed length of the coupling sleeve, the turning tool bar can also be adjusted in the blind hole. Sliding in the through hole to adjust the size of the machining aperture of the tool, the use of fastening screws is convenient for loosening and fixing.

In order to better fix the turning tool bar, the cross-sectional shape of the through hole is the same as that of the turning tool bar.

The turning tool bar of the utility model can be adjusted and installed on the coupling sleeve, and the position of the turning tool bar in the through hole of the coupling sleeve can be adjusted according to the size of the machining aperture, so that the processed concentricity is higher.

The beneficial effects of the utility model are: the turning tool bar of the utility model can be adjusted and installed on the coupling sleeve, and the position of the turning tool bar in the through hole of the coupling sleeve can be adjusted according to the size of the machining aperture, so that the concentricity processed is relatively high. High, to solve the problem that the standard turning tool clamping block of the traditional vertical lathe is too large to process parts with smaller apertures, and some parts have high concentricity requirements and need to be clamped on the vertical lathe to complete the processing. If the tool is changed or the clamping method is changed, the concentricity cannot meet the requirements.

Description of drawings

Fig. 2 is the assembling schematic diagram of handle of the utility model and connecting sleeve;

Fig. 3 is a sectional view of the handle of the utility model.

Among the figure: 1. knife handle, 2. connecting sleeve, 3. turning tool bar, 4. turning blade, 5. pulling nail, 6. blind hole, 7. through hole, 8. fastening screw.

Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

As shown in Figure 1-3, a turning tool with a special coupling sleeve includes a tool handle 1, a coupling sleeve 2, a turning tool bar 3 and a turning blade 4, and a pull stud 5 is fixedly installed on the top of the tool handle 1. 1 The lower surface is provided with a blind hole 6, the coupling sleeve 2 is fixedly installed in the blind hole 6, the lower end of the coupling sleeve 2 is radially opened with a through hole 7, the turning tool bar 3 is fixedly installed in the through hole 7, and the turning blade 4 is fixedly installed At the end of the turning tool holder 3.

The fixing of coupling sleeve 2 and tool handle 1 and the fixing of turning tool and coupling sleeve 2 are all fixed by fastening screws 8. Since coupling sleeve 2 can slide in blind hole 6 to adjust the exposed length of coupling sleeve 2, turning Tool bar 3 can also slide in the through hole 7 to adjust the size of the tool machining aperture, and the fastening screw 8 is used to facilitate loosening and fixing.

In order to fix the turning tool bar 3 better, the cross-sectional shape of the through hole 7 is the same as that of the turning tool bar 3 .

The turning tool bar 3 of the utility model can be adjusted and installed on the coupling sleeve 2, and the position of the turning tool bar 3 in the through hole 7 of the coupling sleeve 2 can be adjusted according to the size of the machining aperture, so that the processed concentricity is higher.

Inspired by the above ideal embodiment according to the utility model, through the above description content, relevant staff can completely make various changes and modifications within the scope of not deviating from the technical idea of the utility model. The technical scope of this utility model is not limited to the content in the description, but must be determined according to the scope of the claims.
