Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and particularly relates to a turning tool for processing a groove side wall. Background Art

[0002] Manufacturing is the basic guarantee for the country to achieve emerging industrialization. With the rapid development of manufacturing, the requirements for the accuracy and efficiency of mechanical processing are getting higher and higher. Traditional turning tools or milling cutters can no longer meet the needs of modern mechanical processing in some aspects. For example, it is necessary to process arc grooves on the inner walls of circular holes on some specific mechanical parts. If traditional mechanical processing methods are used to process them, only one tool cannot complete the processing of the arc grooves on the inner walls of the circular holes. Multiple tools must be used to process the arc grooves on the inner walls of the circular holes. The replacement of multiple tools and the frequent adjustment of tool processing angles reduce the efficiency of mechanical parts processing and the processing accuracy of parts.

[0021] like Figure 1 , 3 As shown, a clamping groove 3 cooperating with a three-jaw chuck is provided on the notch end surface of the circular groove 2 to ensure that the cutter body 1 rotates synchronously and rapidly with the three-jaw chuck.

[0022] like Figure 1 , 2 As shown in FIG. 3 , the No. 1 blade 6 is mounted on the No. 1 blade holder 5 by means of bolts 13, the No. 2 blade 8 is mounted on the No. 2 blade holder 7 by means of bolts 13, the No. 3 blade 10 is mounted on the No. 3 blade holder 9 by means of bolts 13, and the No. 4 blade 12 is mounted on the No. 4 blade holder 11 by means of bolts 13, so that the No. 1 blade, the No. 2 blade, the No. 3 blade and the No. 4 blade can be disassembled and replaced.

[0026] During the process of clamping the tool, if it is necessary to machine an arc groove 16 on the inner wall of the circular hole 15 of the casting 14, the utility model should be first installed on the three-jaw chuck of the lathe so that the circular groove 2 at one end of the tool body 1 and the clamping groove 3 on the notch end of the circular groove 2 of the tool body 1 form a clamping connection with the three-jaw chuck, and then the clamp for clamping the casting 14 is started to drive the casting 14 to move axially toward the utility model and make the utility model enter the circular hole 15 on the casting 14, and then drive the live center to enter the circular hole 15 of the casting 14 and push into the conical groove 4 at one end of the tool body 1 to complete the clamping of the utility model.

[0027] 2. Cutting and finishing the arc groove 16: Start the lathe spindle, which drives the utility model to rotate through the three-jaw chuck, and then start the fixture for clamping the casting 14. The fixture drives the casting 14 to perform reciprocating radial and axial movements according to the axial width and radial depth of the arc groove 16 to be processed. The No. 2 blade 8, the No. 3 blade 10 and the No. 4 blade 12 on both axial sides of the cutter body 1 cut and finish the two planar end walls 1602 of the arc groove 16, and the No. 1 blade 6 at the radial outer ends of the cutter body 1 cut and finish the arc wall 1601 of the arc groove 16.

[0028] In the process of using the utility model to perform cutting and finishing on the arc groove 16, there is no need to replace the tool and frequently adjust the cutting angle of the tool. The utility model can perform cutting and finishing on the arc wall 1601 of the arc groove 16 and a plane end wall 1602 of the arc groove 16 at one time and complete the finishing of the second plane end wall 1602 of the arc groove 16 and the arc wall 1601 of the arc groove 16 at one time without replacing the tool and adjusting the cutting angle of the tool, thereby having higher machining efficiency and higher machining accuracy.
