Problems solved by technology

[0002] The viscose composite sound-absorbing saw blade base is a high-grade saw blade base with excellent sound-absorbing function that was first created by the applicant company by using an advanced adhesive bonding process method. This kind of saw blade has a soft glue adhesive sandwich structure , Using the single-thick pressure plate clamping method of ordinary vertical lathes to carry out outer circle finish turning can easily cause the problem of sheet structure damage and outer circle burrs too large. It is particularly obvious in the finishing machining of the outer circle of the matrix, which has a great impact on the quality of batch product processing. Therefore, the non-destructive finishing turning method of the outer circle of the viscose compound noise-absorbing saw blade is the most important method in the finishing of this type of saw blade matrix. A major technical difficulty

Embodiment 1

[0017] Such as figure 1 , figure 2 As shown, according to the central hole size D1 of the small viscose composite noise-absorbing saw blade matrix 6 to be subjected to outer circle finishing, select the central shaft 3 with a diameter of D1-0.01mm, and select the centering fine thread connection with the selected central shaft 3 transition sleeve 2, and the transition sleeve 2 is connected with the centering fine thread of the horizontal lathe spindle turntable 1, and the transition sleeve 2 is centered and installed on the horizontal lathe spindle turntable 1, and then the central shaft 3 is centered and installed on the transition On the sleeve 2, the small viscose composite sound-absorbing saw blade base 6 that needs to be fine-turned from D2 to D3 for the inner hole that has been finished is passed through a backing plate 4, multiple inner circular spring steel plates 5.1, and outer circular spring steel plates. 5.2. A pressure plate 7, an end pad 8 and a locking nut 9 a...

Embodiment 2

[0020] In a preferred scheme, the inner circular spring steel plate 5.1 and the outer circular spring steel plate 5.2 are highly elastic steel plates made of materials such as 65Mn, and the selected steel plate has a thickness range of 0.2 mm to 0.35 mm and a flatness of 0.25 mm. The number is the same and not less than five, because practice has proved that the clamping effect of such a number and type of circular spring steel plates is the best.

Embodiment 3

[0022] In a preferred solution, the rotation direction of the spindle turret 1 of the horizontal lathe is opposite to the tightening direction of the transition sleeve 2 and the central shaft 3, so that the central shaft 3 will not loosen during actual operation, effectively ensuring stable machining accuracy sex and safety.

Abstract

The invention relates to a cylindrical nondestructive finish turning machining method for a small-sized viscose composite silencing sawblade matrix. The cylindrical nondestructive finish turning machining method is characterized in that through a cushion plate, round spring steel plates, a pressing plate, an end part cushion block and a locking nut, the small-sized viscose composite silencing sawblade matrix to be subjected to cylindrical turning is centered and clamped on a demountable center shaft fixed by fine threads of a horizontal lathe; after clamping, a main shaft turntable of the horizontal lathe is started to rotate in the direction opposite to the screwing direction of the center shaft, and then a lathe tool does back-and-forth bi-directional motion in the direction parallel to an axis of the center shaft so as to realize cylindrical turning. According to the cylindrical nondestructive finish turning machining method, the operation simplicity of an assembly and disassembly clamp for cylindrical finish turning processing of the small-sized viscose composite silencing sawblade matrix is realized, the monitoring and the detection in the turning process of the small-sized viscose composite silencing sawblade matrix are facilitated, the concentric accuracy stability and the replacement of simplicity of a mandrel are improved, the clamping effect is excellent, the turning burrs of a viscose composite sheet body are effectively reduced, the high-quality non-destructive cylindrical finish machining of the sawblade matrix is realized, and a powerful technical support is provided for the finish machining of the small-sized viscose composite silencing sawblade matrix.
