Description

Technical Field

[0001] This utility model relates to the field of milling equipment technology, and in particular to a milling edge device with material allowance. Background Technology

[0002] The chamfer on the bushing makes it easier to insert into the mounting base and reduces resistance during installation. The chamfering can be achieved by milling the side of the bushing material during its fabrication. For example, Chinese patent CN202022008242.9 discloses a steel socket ring chamfering device, which includes a steel strip unwinding mechanism, a steel strip leveling mechanism, a steel strip positioning mechanism, and a milling and chamfering mechanism. The steel strip leveling mechanism is connected to the steel strip unwinding mechanism, the steel strip positioning mechanism is connected to the steel strip leveling mechanism, and the milling and chamfering mechanism corresponds to the steel strip positioning mechanism. This steel socket ring chamfering device uses longitudinal positioning rollers and longitudinal positioning pressure rollers to longitudinally position the steel strip, and transverse positioning side rollers to transversely position the steel strip. Simultaneously, a milling cutter disc is used to mill the edges of the steel strip, forming a guide slope. The steel strip moves under the traction of the leveling rollers and leveling pressure rollers and is leveled. However, this device cannot adjust the size of the milled chamfer, and the milling accuracy is not efficient. Summary of the Invention

[0015] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0016] like Figure 1 The diagram shows the structure of the milling device with material allowance provided by this utility model. The milling device includes a machine base 10, two milling stabilizing components 20 spaced apart on the machine base 10, a rough milling component 30 disposed on one side of one of the milling stabilizing components 20, and a finish milling component 40 disposed on one side of the other milling stabilizing component 20. It is conceivable that the milling device with material allowance also includes other functional modules, such as a power supply module, a conveying module, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0017] Please refer to the following: Figures 2 to 4The strip milling equipment is used to rough and finish mill a strip 50 to form a strip with chamfers 52 on both sides, which can then be rolled into bushings, bearings, etc. The strip 50 is transported by a conveyor module.

[0018] The machine tool 10 is provided with two funnels 11 corresponding to the positions of the two milling stabilizing components 20. The two funnels 11 are located on the side of the machine tool 10 away from the milling stabilizing components 20, and the machine tool 10 has two openings that are respectively connected to the funnels 11 so that the debris generated during the milling process falls into the funnels 11. It can be imagined that a receiving box (not shown) is provided at the end of the funnel 11 away from the milling stabilizing components 20 to catch the debris falling from the funnel 11.

[0019] The milling stabilizing assembly 20 includes two X-axis lead screws 21 arranged opposite to each other, two X-axis sliders 22 respectively screwed to the two X-axis lead screws 21, two Y-axis lead screws 23 respectively disposed on the two X-axis sliders 22, two Y-axis sliders 24 respectively screwed to the two Y-axis lead screws 23, and two clamping plates 25 respectively disposed on the two Y-axis sliders 24.

[0020] The length directions of the two X-axis lead screws 21 are parallel and coincident. Rotating the two X-axis lead screws 21 controls the sliding of the two X-axis sliders 22 and drives the Y-axis lead screw 23 to move away from or closer to each other. This, in turn, limits the material strip 50 through the two clamping plates 25, thereby improving the stability during milling.

[0021] The two X-axis lead screws 21 are located on both sides of a funnel 11, so that the milled waste can fall accurately into the funnel 11.

[0022] The two Y-axis lead screws 23 are parallel to each other in length direction. Rotating the two Y-axis lead screws 23 controls the sliding of the two Y-axis sliders 24, thereby aligning them with the clamping surfaces of the two clamping plates 25 to enhance the stability of the strip 50 during milling.

[0023] An L-shaped clamping block 26 is provided on the clamping plate 25. One end face of the two L-shaped clamping blocks 26 is arranged opposite each other and makes gap contact with the material strip 50.

[0024] An adjustment knob 27 is provided at one end of the X-axis lead screw 21 and the Y-axis lead screw 23. The adjustment knob 27 is marked with a rotation scale, which can precisely control the relative position of the two clamping plates 25, thereby accurately limiting the material strip 50 to prevent the material strip 50 from shaking during milling.

[0025] On one side of the milling stabilizing assembly 20, located on one side of the precision milling assembly 40, each of the two L-shaped clamping blocks 26 is provided with a limiting block 28, which is located between the L-shaped clamping block 26 and the clamping plate 25. One opposite end face of the two limiting blocks 28 has a limiting groove 29, the width of which matches the width of the strip 50. Thus, when the strip 50 passes through the two limiting grooves 29, its four surfaces (top, bottom, left, and right) can be stably contained within the two limiting grooves 29, thereby further improving the stability of the strip 50 during the precision milling process.

[0026] A pad 310 is provided between the milling stabilizing component 20 located on one side of the fine milling component 40 and the machine table 10 to increase the height of the milling stabilizing component 20, so that the clamping surface on the milling stabilizing component 20 located on one side of the rough milling component 30 matches the two limiting grooves 29.

[0027] The rough milling assembly 30 includes two X-axis milling screws 31 respectively disposed on both sides of the funnel 11, two X-axis milling sliders 32 respectively screwed onto the two X-axis milling screws 31, two Z-axis milling screws 33 respectively disposed on the two X-axis milling sliders 32, two Z-axis milling sliders 34 respectively screwed onto the two Z-axis milling screws 33, two rough milling motors 35 respectively disposed on the two Z-axis milling sliders 34, and two rough milling cutters 36 respectively disposed on the two rough milling motors 35.

[0028] Two X-axis milling screws 31 are located on both sides of the milling stabilizing assembly 20, so that the two rough milling cutters 36 can be positioned one in front of the other on both sides of the milling stabilizing assembly 20, thereby milling the two sides of the strip 50.

[0029] Rotating the two X-axis milling screws 31 controls the sliding of the two X-axis milling sliders 32 and drives the two Z-axis milling screws 33 to move closer or further away from each other, thereby causing the two rough milling cutters 36 to move closer or further away from the sides of the strip 50 for rough milling operations.

[0030] Rotating the two Z-axis milling screws 33 controls the sliding of the two Z-axis milling sliders 34 and drives the two roughing motors 35 to move, thereby controlling the height of the roughing motors 35 and making full use of the roughing cutter 36. That is, when one cutting edge of the roughing cutter 36 is worn, the height of the roughing cutter 36 is raised or lowered so that the other cutting edge of the roughing cutter 36 can perform roughing operations.

[0031] One end of the X-axis milling screw 31 and the Z-axis milling screw 33 are respectively provided with an adjusting valve 37. The adjusting valve 37 is marked with a rotation scale, so as to accurately control the position of the two rough milling cutters 36, thereby performing precise milling on the strip 50 and improving the milling accuracy.

[0032] The roughing motor 35 drives the roughing cutter 36 to rotate for milling operations. The two roughing cutters 36 are inclined to the milling surface of the strip 50, that is, the length direction of the roughing cutter 36 has an inclination angle of 45° or 60° with the side of the strip 50. Thus, after milling the strip 50, the two sides of the strip 50 will form a 45° or 60° inclined surface 51, thereby forming a chamfer 52 in the subsequent finish milling operation.

[0033] The precision milling assembly 40 includes two two-axis moving parts 41 located on both sides of a funnel 11, two precision milling motors 42 respectively disposed at the output ends of the two two-axis moving parts 41, and two precision milling cutters 43 respectively disposed at the output ends of the two precision milling motors 42.

[0034] The structure and function of the two-axis moving component 41 are the same as those of the moving component in the rough milling assembly 30, that is, to control the finish milling cutter 43 to perform milling operations on the strip 50 from two directions.

[0035] The milling motor 42 drives the milling cutter 43 to rotate for milling operations. The length direction of the two milling cutters 43 is parallel to the two sides of the strip 50. After the milling cutter 43 finishes milling the strip 50, a portion of the two inclined surfaces 51 on the strip 50 will form a plane 53, which will serve as the two end faces of the bushing after rolling. The remaining inclined surfaces 51 form the chamfer 52.

[0036] The milling cutter 43 is inclined to the surface of the strip 50, that is, the length direction of the milling cutter 43 has an inclined angle with the upper and lower surfaces of the strip 50. This can improve the milling surface of the milling cutter 43, thereby reducing the wear of the cutting edge and increasing its service life.

[0037] Compared with the prior art, the milling equipment with material allowance provided by this utility model limits the two sides of the strip 50 through the milling stabilizing component 20, and the limiting grooves 29 on the two limiting blocks 28 further limit the four surfaces of the strip 50, thereby enhancing the stability of the strip 50 during milling and improving the milling accuracy. The two roughing cutters 36 are inclined to the milling surface of the strip 50, so that the strip 50 forms bushings or bearings with chamfers after segmented rolling. Moreover, both the roughing cutter 36 and the finishing cutter 43 can be flexibly adjusted to change the degree of milling and control the size of the chamfer. The milling equipment with material allowance has high milling accuracy and strong stability.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
