Embodiment 1

[0035] Combine figure 1 with figure 2 A profiling lathe with a cutting compensation mechanism in this embodiment is mainly composed of a lathe body 1, a pull plate 501, a pallet 502, a tool holder 3, a cutting compensation mechanism 2, and a profiling mechanism. Wherein, the pallet 502 and the lathe body 1 are driven by a screw, so that the pallet 502 slides longitudinally along the lathe body 1, that is, moves along the axial direction of the workpiece 4 to be processed. Such as image 3 As shown, the pallet 502 is provided with a tenon, and the lower part of the pull plate 501 is a tongue and groove structure. The pull plate 501 is slidably connected with the pallet 502 through the cooperation of the tongue and groove and the tenon. The pull plate 501 can slide laterally along the pallet 502 . Fixing the knife holder 3 on the pull plate 501 drives the knife holder 3 to slide while the pull plate 501 slides.

Embodiment 2

[0046] The basic structure of a profiling lathe with a cutting compensation mechanism of this embodiment is the same as that of the first embodiment. The difference is that in the outer sleeve groove 205 and the inner sleeve groove 207, the limit rod 206 protrudes to The width of the linear sliding section is 0.25 times the diameter of the limit rod 206. The outer groove inclined section 2051 and the inner groove inclined section 2071 are composed of a first inclined section and a second inclined section. The first inclined section is connected with the linear sliding section. , And the angle between the first inclined section and the direction of the linear sliding section is smaller than the angle between the second inclined section and the direction of the linear sliding section. The purpose of switching the limit rod 206 can also be achieved through two inclined sections.

Embodiment 3

[0048] The basic structure of a profiling lathe with a cutting compensation mechanism of this embodiment is the same as that of the first embodiment. The difference is that a dust cover 211 is fitted on the outer circumference of the external compression spring 204 to prevent dust from entering the outer sleeve 203 and the inner sleeve 208 affect its slidability. A sliding sleeve 210 is provided on the support plate 502, and the sliding sleeve 210 can prevent the shaft 202 from being worn out and ensure its sliding properties. Since the movement deformation of the external compression spring 204 exceeds 2D / 3, it will be difficult to provide the force required for the concave arc of the profiling surface, so the distance between the engagement section in the outer sleeve groove 205 and the engagement section in the inner sleeve groove 207 It can be set to 2D / 3, and the resistance compensated by the internal compression spring 209 does not exceed the maximum resistance exerted by...

Abstract

The invention discloses a copying lathe provided with a cutting compensation mechanism and belongs to the field of copying lathes. The copying lathe comprises a lathe body, a pull plate, a supporting plate and a tool apron. The supporting plate slides along the lathe body in the longitudinal direction, the pull plate is connected with the supporting plate in a sliding mode, the pull plate is made to slide along the supporting plate in the transverse direction, and the tool apron is fixed to the pull plate. The lathe further comprises the cutting compensation mechanism and a profiling mechanism. The profiling mechanism comprises a profiling depended wheel and a curved surface template. The profiling depended wheel is arranged in adjusting holes in the pull plate through a connection rod, and the cutting compensation mechanism controls the profiling depended wheel to be matched with the profiling face of the curved surface template through the pull plate. According to the copying lathe, the cutting compensation mechanism compensates the cutting force generated in the machining process, sufficient cutting force is guaranteed, abrasion to the profiling mechanism is relieved, machining accuracy is improved, the service life is prolonged, reformation is achieved easily, and the production cost is lowered.

Description

Technical field [0001] The invention relates to the technical field of profiling lathes, and more specifically, to a profiling lathe with a cutting compensation mechanism. Background technique [0002] The cylindrical surface can be easily machined on the workpiece with ordinary lathes and grinders, and the normal of the cylindrical surface is a straight line. However, it is difficult to machine curved surfaces on workpieces with ordinary lathes and grinders. Therefore, for workpieces that require curved surface processing, most of them are processed by CNC lathes. For small and medium-sized enterprises, the price of CNC lathes is relatively high, especially for large-scale shaft parts, and large-scale CNC lathes need to be purchased. The economic strength of small and medium-sized enterprises is unbearable, which leads to the processing problems of curved shaft parts. [0003] After continuous exploration and research, those skilled in the art have developed a method for machinin...
