Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following further describes the technical solution of the present invention with reference to the drawings and the embodiments.

Referring to fig. 1 to 5, a grinding device for turning is shown, which is integrally mounted on a tool rest 10 and contacts a workpiece (as shown by 60) to grind along with the movement of the tool rest 10, and comprises a mounting structure mounted on the tool rest 10, a driving mechanism arranged on the mounting structure, and a grinding wheel 20 arranged at one end of the driving mechanism. After a workpiece (the workpiece structure includes a cylindrical or plate-shaped rotating workpiece clamped on the lathe spindle 40) is turned by the lathe, the turning tool is detached from the tool rest 10, the grinding device is integrally assembled and fastened on the tool rest 10 through the assembling structure, the grinding wheel 20 can be contacted with the surface of the workpiece to adjust the grinding depth along with the position adjustment (such as longitudinal adjustment along the lathe body) and the moving action (moving towards the direction of the lathe spindle 30) of the tool rest, and the grinding wheel 20 is driven to rotate at a high speed under the driving action of the driving mechanism, so that the surface of the turned workpiece is ground. The operation mode avoids the heavy operation of repeatedly clamping the workpiece (particularly the operation process that the workpiece is dismounted from the lathe spindle and then is mounted on the grinding machine again), can solve the problem that the conventional grinding machine is difficult to grind the plate workpiece, reduces the accumulated error of repeatedly clamping the workpiece, combines the turning and grinding operations into an integrated operation mode, optimizes the processing technology, improves the final forming precision of the workpiece, and reduces the manual labor of operators.

Specifically, as shown in fig. 1, the tool holder 10 is a vertically arranged square block, a tool mounting groove 101 is horizontally and annularly arranged at the top of the square block, and fastening bolts 30 penetrating through the tool mounting groove 101 and abutting against a tool are arranged at the top of the square block along the circumferential direction at intervals. As shown in fig. 4, the assembling structure includes an assembling support plate 1, and a square hole 1a for sleeving the assembling support plate 1 in the tool assembling groove 101 is formed in the assembling support plate 1. After the turning process is completed and the turning tool is detached, the assembly support plate 1 is integrally sleeved on the tool rest 10 in a surrounding manner through the annular sleeve matching of the square hole 1a and the tool assembly groove 101, the assembly support plate 1 is tightly pressed at the edge position of the square hole 1a through the fastening bolts 30, the fastening assembly of the support plate and the tool rest 10 is realized, the grinding wheel 20 and the turning tool can be adjusted and moved along with the tool rest 10, and the grinding process of the turned workpiece is realized.

In order to facilitate the assembly and disassembly of the assembly support plate 1 and the tool rest 10, as shown in fig. 4-5, the side edge of the assembly support plate 1 on one side of the square hole 1a is divided into a surrounding plate 11 hinged to the body of the assembly support plate 1, and the surrounding plate 11 forms the square hole 1a with the body of the assembly support plate 1 in a rotating state. During assembly, the surrounding plate 11 is rotated to open the square hole 1a (shown in fig. 5), the assembly supporting plate 1 is horizontally clamped in the tool assembly groove 101, then the surrounding plate 11 is rotated reversely to surround and close the square hole 1a (shown in fig. 4), and finally the fastening bolts 30 on the tool holder 10 are pressed on the assembly supporting plate 1 body and the surrounding plate 11, so that the rapid assembly operation of the assembly supporting plate 1 and the tool holder 10 is realized. When the tool is disassembled, the fastening bolt 30 is loosened, the square hole 1a is rotated and opened around the plate 11, and the assembly supporting plate 1 is disassembled from the tool rest 10.

In order to avoid the problem that the square hole 1a is opened under the action of external force on the surrounding plate 11 in the grinding process, a limiting plate 11a smaller than the thickness of the surrounding plate is extended from the outer end of the surrounding plate 11, a limiting groove 1b matched with the limiting plate 11a to be embedded is formed in the body of the assembling supporting plate 1, and fastening holes 1c are formed in the positions, corresponding to the limiting groove 1b, of the limiting plate 11 a. After the body of the assembly supporting plate 1 is annularly sleeved in the cutter assembly groove 101, the surrounding plate 11 is rotated to surround and seal the square hole 1a, meanwhile, the limiting plate 11a of the surrounding plate 11 is nested in the limiting groove 1b of the cutter holder 10, the limiting plate 11a corresponds to the fastening hole 1c of the limiting groove 1b, and finally, a bolt (shown in figure 50) is preferably loaded into the fastening hole 1c to fix the surrounding plate 11 in a sealed state, so that the defect that the surrounding plate 11 is opened due to the grinding external force is overcome.

In order to further improve the assembly tightness of the assembly support plate 1 and the tool rest 10, fastening blind holes 1d which are pressed by the fastening bolts 30 are formed on the surfaces of the assembly support plate 1 body and the surrounding plate 11. After the square hole 1a is sealed by the surrounding plate 11, the fastening bolts 30 are screwed and pressed in the corresponding fastening blind holes 1d, so that the integral limiting and fastening effect of the assembly supporting plate 1 is realized.

Specifically, the driving mechanism comprises a driving shaft 2 fixed on the assembly supporting plate 1 on one side of the square hole 1a, a driving motor 3 connected with the driving shaft 2 is arranged at one end of the driving shaft 2, and the grinding wheel 20 is fastened to the other end of the driving shaft 2 in a hanging manner. After the assembly supporting plate 1 is assembled and fastened in the above manner, the grinding depth of the grinding wheel 20 is adjusted through the adjusting action of the tool rest 10, and finally the driving motor 3 is started to drive the grinding wheel 20 to rotate at a high speed, and the grinding operation on the workpiece is completed under the automatic moving action of the tool rest 10.
