Embodiment 1

[0024] On the one hand, this embodiment provides a turning tool with adjustable cutting force, see figure 1 , which includes a blade 1, a cutter bar 2 and a cutting force regulating device, wherein:

[0025] The blade 1 is mounted on the first end of the cutter bar 2;

[0026] The cutting force adjustment device includes a controller and a cutting force detection mechanism 3 connected with the controller signal, the controller and a cutting force adjustment mechanism. The cutting force detection mechanism 3 is installed on the cutter bar 2 to detect the reaction force of the blade 1 during cutting. , the cutting force adjustment mechanism includes the cutter bar feed adjustment power unit and the cutter bar fixing frame 4, the cutter bar fixing frame 4 is fixed on the second end of the cutter bar 2, and the knife is driven by the cutter bar 2 feed amount adjusting power unit. The rod fixing frame 4 reciprocates along the axis direction of the cutter rod 2 .

[0027] The cutt...

Embodiment 2

[0030] On the basis of Embodiment 1, the blade 1 is fixed on the first end of the cutter bar 2 , or the blade 1 and the cutter bar 2 are integrally formed. Alternatively, the turning tool is a rotatable turning tool. Which turning tool to choose depends on the actual situation. In order to meet a wider scope of application.

Embodiment 3

[0032] On the basis of Embodiment 1 or 2, one mode of the cutting force detection mechanism 3 is a strain gauge, and the strain gauge is closely attached to the outer surface of the cutter bar 2 or the lower surface of the blade 1 to respectively obtain the cutting force of the cutter bar during cutting. 2. The reaction force of blade 1. The strain gauge technology is mature and easy to promote in the industry.

[0033] One way of adjusting the feed rate of the knife bar is the hydraulic pump 5, the control end of the hydraulic pump 5 is connected with the controller signal, the hydraulic pump 5 is connected with the hydraulic cylinder through the hydraulic pipeline 6, and the cylinder body 7 of the hydraulic cylinder is connected with the knife The rod holder 4 is fixed, and the action end 8 of the hydraulic cylinder is fixed with the knife rod 2 . When it is necessary to reduce the feed rate of the turning tool, the controller sends a working signal to the hydraulic pump 5,...

Abstract

The invention discloses a cutting-force-adjustable turning tool and a turning lathe with the same. The turning tool comprises a blade, a turning tool rod and a cutting force adjusting device. The blade is mounted at the first end of the turning tool rod. The cutting force adjusting device comprises a controller, a cutting force detecting mechanism and a cutting force adjusting mechanism, wherein the cutting force detecting mechanism and the cutting force adjusting mechanism are in signal connection with the controller; the cutting force detecting mechanism is mounted on the turning tool rod soas to detect the counter-acting force of the blade during cutting; the cutting adjusting mechanism comprises a turning tool rod feeding amount adjusting power unit and a turning tool rod fixing rack;the turning tool rod fixing rack is fixed to the second end of the turning tool rod; and the turning tool rod fixing rack reciprocates in the axis direction of the turning tool rod under driving of the turning tool rod feeding amount adjusting power unit. The cutting-force-adjustable turning tool and the turning lathe with the same have the beneficial effects that the stressing condition of the blade and the turning tool rod is detected dynamically in real time, the stress of the blade and the turning tool rod is controlled to be within a certain range, then the damage to the blade and the turning tool rod is avoided, the cost is reduced, and cutting is finished smoothly.

Description

technical field [0001] The invention relates to the technical field of machining equipment, in particular to a turning tool with adjustable cutting force and a lathe including the same. Background technique [0002] The lathe completes the cutting process of the workpiece through the relative movement of the turning tool and the workpiece. When the hardness of the workpiece is high, or there are points with high hardness in the workpiece, in order to prevent damage to the turning tool, the method of reducing the feed rate of the turning tool is usually adopted to prevent the tool bar of the turning tool from being broken. [0003] However, the above method has a certain effect on preventing the breakage of the knife bar, but it cannot completely prevent the knife bar from being broken. Contents of the invention [0004] The object of the present invention is to provide a turning tool with adjustable cutting force and a lathe including the same, so as to solve the existing...
