Embodiment 1

[0035] to combine figure 2 and image 3 , a cutting compensation mechanism for a profiling lathe in this embodiment is mainly composed of a shaft rod 202, an outer sleeve 203, an external compression spring 204, a compression spring retaining core 206, an inner sleeve 208, and an internal compression spring 209, etc., wherein, The inner sleeve 208 is slidingly connected with the outer sleeve 203, and the outer compression spring 204 is sleeved on the outer sleeve 203. One end of the outer compression spring 204 is against the inner sleeve baffle plate 210 on the inner sleeve 208, and the other end of the outer compression spring 204 Against the outer sleeve baffle plate 211 on the outer sleeve 203 , it is used to provide force for the outer sleeve 203 to slide relative to the inner sleeve 208 . The shaft 202 in this embodiment is installed coaxially with the inner sleeve 208, the outer end of the shaft 202 is provided with an adjustment plate 201, and the other end of the sh...

Embodiment 2

[0043] combine Figure 6 , a kind of profiling lathe cutting compensating mechanism of this embodiment, its basic structure is the same as that of Embodiment 1, and its difference is: the compression spring stop core 206 in this embodiment is directly fixed with the end of internal compression spring 209 Even, the compression spring retaining core 206 can still achieve the purpose of switching between the inner sleeve 208 and the outer sleeve 203 .

Embodiment 3

[0045] The basic structure of the cutting compensation mechanism for a profiling lathe in this embodiment is the same as in Embodiment 1, the difference is that in the outer sleeve groove 205 and the inner sleeve groove 207, the compression spring retaining core 206 protrudes to the linear slide The width of the shifting section is 0.25 times of the diameter of the clip spring retaining core 206, and the angle between the inclined section 2071 of the inner groove and the vertical direction is 40°. The longitudinal distance design of the upper left end point of 2071 can also design the inclined section 2051 of the outer groove and the inclined section 2071 of the inner groove to be composed of the first inclined section and the second inclined section, the first inclined section is connected with the linear sliding section, and the second The included angle between the first inclined section and the direction of the straight-line sliding section is smaller than the included angl...

Abstract

The invention discloses a copying lathe cutting compensation mechanism, and belongs to the field of copying machining. The copying lathe cutting compensation mechanism comprises a shaft lever, an outer sleeve, an outer compressed spring, a compressed spring blocking core, an inner sleeve and an inner compressed spring, wherein the inner sleeve is connected with the outer sleeve in a sliding mode, the outer compressed spring is arranged on the outer sleeve in a sleeving mode, one end of the outer compressed spring abuts against an inner sleeve baffle on the inner sleeve, and the other end of the outer compressed spring abuts against an outer sleeve baffle on the outer sleeve; the shaft lever and the inner sleeve are coaxially installed, and an adjusting plate of the outer end of the shaft lever is attached to the outer sleeve baffle; the inner compressed spring is arranged in the inner sleeve, the end, extending into the inner sleeve, of the inner compressed spring is connected with the cylindrical compressed spring blocking core, a clipped object of the compressed spring blocking core is controlled to switch between the inner sleeve and the outer sleeve, and the cutting compensation is achieved. According to the copying lathe cutting compensation mechanism, the outer compressed spring is matched with the inner compressed spring to conduct the copying machining, enough cutting fore is guaranteed, abrasion to a copying mechanism is reduced, the machining accuracy is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of profiling processing, and more specifically, relates to a cutting compensation mechanism of a profiling lathe. Background technique [0002] The cylindrical surface can be easily processed on the workpiece with ordinary lathes and grinders, and the normal of the cylindrical surface is a straight line. However, it is difficult to process curved surfaces on workpieces with ordinary lathes and grinders. Therefore, for workpieces that require curved surface processing, CNC lathes are used to complete curved surface processing. For small and medium-sized enterprises, the price of CNC lathes is high, especially for large-scale shaft parts, it is necessary to purchase large-scale CNC lathes, which is difficult to bear due to the economic strength of small and medium-sized enterprises, resulting in the processing of curved surface shaft parts. [0003] After continuous exploration and research, those skilled in ...
