Technical Field

[0001] The invention relates to a milling cutter assembly and a method, and in particular to a follower milling cutter assembly and a method. Background Art

[0002] A milling cutter is a rotary tool with one or more teeth used for milling. When the milling cutter is working, each tooth cuts off the excess of the workpiece intermittently in sequence. The milling cutter is mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines.

[0003] When the milling cutter performs small-scale processing on a plane, such as milling burrs on the plane or welds between multiple workpieces, the plane to be processed often has an incorrect position tilt when it is fixed, and the existing milling cutter cannot make adaptive follow-up adjustments to the plane with an incorrect position tilt after being set up. This makes the existing milling cutter have a poor processing effect when performing small-scale processing on the plane, and even misses the weld when milling the weld. Summary of the invention

[0010] Furthermore, a fixed plate A with a corresponding position is arranged at the rear of the linear guide rail, and the fixed plate A is fixedly arranged on the adjustment plate; the rear end of the screw rod A passes through the fixed plate A and is matched and connected with a nut A, and the position of the screw rod A is fixed by the matching and locking of the nut A and the screw rod A.

DETAILED DESCRIPTION

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] like Figure 1 As shown, a follower milling cutter assembly includes a milling cutter slide mechanism 1 and a milling cutter mechanism 2. The milling cutter mechanism 2 is arranged on the milling cutter slide mechanism 1, and the milling cutter slide mechanism is used to drive the milling cutter mechanism to move linearly.

[0039] like Figure 2 As shown, the milling cutter mechanism 2 includes a motor 3 and a follower mechanism. The motor 3 is fixedly arranged on a motor fixing seat 4. The output end of the motor 3 is fixedly connected to a milling cutter 6. The motor drives the milling cutter 6 to rotate to perform milling processing on the workpiece to be processed.

[0040] The motor adapter plate 5 is symmetrically arranged on the left and right sides of the motor fixing seat 4. The rod end joint bearing 13 is symmetrically arranged on the left and right sides of the motor fixing seat 4. The rod end joint bearing 13 is located between the motor adapter plate 5 and the motor fixing seat 4. The rear end of the rod end joint bearing 13 is fixedly connected with a screw B14. The left and right sides of the motor fixing seat 4 are both provided with a rotating shaft 20 corresponding to the position of the rod end joint bearing 13. The rotating shaft 20 passes through the inner ring of the rod end joint bearing 13 and is fixedly connected to the motor adapter plate 5.

[0041] like Figure 3 As shown, the milling cutter slide mechanism 1 includes a slide cylinder 15 and a slide cylinder fixing plate A16. The slide cylinder 15 is arranged on the machine tool through the slide cylinder fixing plate A16. A slide cylinder adapter 17 is fixedly arranged above the slide of the slide cylinder 15. The slide cylinder adapter 17 is located behind the motor adapter plate 5. The gap between the slide cylinder adapter 17 and the motor adapter plate 5 along the front-to-back direction can be adjusted according to the actual processing conditions. The gap between the slide cylinder adapter 17 and the motor adapter plate 5 along the front-to-back direction determines the rotation angle of the milling cutter of the milling cutter mechanism in the vertical direction. When there is no gap between the slide cylinder adapter seat 17 and the motor adapter plate 5, the rotation angle of the milling cutter in the vertical direction cannot be adjusted; when there is a gap between the slide cylinder adapter seat 17 and the motor adapter plate 5, the gap provides space for the milling cutter mechanism to rotate around the rotating shaft 20, and the slide cylinder adapter seat 17 limits the rotatable motor adapter plate; when the motor adapter plate 5 rotates around the rotating shaft 20 along with the motor fixing seat, when the motor adapter plate 5 collides with the slide cylinder adapter seat 17, the motor adapter plate 5 stops rotating, and the motor adapter plate 5 is limited, thereby limiting the rotation angle of the milling cutter 6; the existence of the gap between the slide cylinder adapter seat 17 and the motor adapter plate 5 makes the inclination angle of the milling cutter in the vertical plane not fixed, but can be rotated and adjusted, and the rotation angle of the milling cutter is limited by the size of the gap between the slide cylinder adapter seat 17 and the motor adapter plate 5.

[0042] The left inner wall and the right inner wall of the slide cylinder adapter 17 are symmetrically provided with sleeves 18, and the positions of the sleeves 18 and the screw B14 correspond, and the screw B14 passes through the sleeve 18; two nuts are provided on the screw B14, and the two nuts are nut B14 and nut C25 respectively; nut C25 is located on the front side of the sleeve 18, and the rear end of the screw B14 passes through the sleeve 18 and is connected with the nut B19 to realize the connection between the milling cutter mechanism and the milling cutter slide mechanism.

[0043] Because the milling cutter mechanism is fixedly connected to the rotating shaft 20, the outer sleeve of the rotating shaft 20 is provided with a rod end joint bearing 13, and the rotating shaft 20 can rotate relative to the rod end joint bearing 13; a screw B14 is fixedly connected to the rod end joint bearing 13, and the screw B14 is inserted into the sleeve 18 and is locked and fixed by the nut C and the nut B located at the front and rear sides of the sleeve 18. The sleeve 18 is fixedly arranged on the slide cylinder adapter 17, and the slide cylinder adapter 17 is arranged on the slide cylinder fixing plate 16 through the slide cylinder 15. The slide cylinder fixing plate 16 is fixedly arranged on the machine tool. Therefore, the position of the rod end joint bearing 13 relative to the milling cutter slide mechanism 1 and the machine tool in the vertical direction is fixed and will not rotate. Since the rotating shaft 20 inserted in the rod end joint bearing can rotate relative to the rod end joint bearing, the milling cutter mechanism fixedly connected to the rotating shaft 20 can rotate in the vertical direction, so that the vertical rotation angle of the milling cutter 6 can be adjusted, and the milling position of the workpiece to be processed can be adjusted in time.

[0044] When the follower milling cutter assembly of the present invention is working, the screw B is fixed by the cooperation and locking of the nut B, the nut C and the screw B, so that the gap between the slide cylinder adapter seat 17 and the motor adapter plate 5 remains unchanged, and the rotation range of the milling cutter in the vertical plane is limited; when it is necessary to adjust the gap between the slide cylinder adapter seat 17 and the motor adapter plate 5, the nut C and the nut B are loosened, and the user adjusts the front and rear positions of the screw B relative to the sleeve 18, and then locks the nut C and the nut B, so as to adjust the gap between the slide cylinder adapter seat 17 and the motor adapter plate 5, and then adjust the rotation angle range of the milling cutter in the vertical plane, so that the milling cutter can automatically follow the inclination angle of the milling cutter as the surface of the workpiece is processed when the milling cutter is working.

[0045] Therefore, the rotation of the milling cutter mechanism 2 relative to the milling cutter slide mechanism 1 is achieved through the relative rotation of the rotating shaft 20 and the rod end joint bearing 13. Since the slide cylinder fixing plate of the milling cutter slide mechanism 1 is fixedly arranged on the machine tool, the milling cutter mechanism can rotate a certain range relative to the machine tool in the vertical plane.

[0046] The existence of the gap between the slide cylinder adapter seat 17 and the motor adapter plate 5 enables the milling cutter mechanism of the follower milling cutter assembly of the present invention to swing in a vertical plane; the front side wall of the slide cylinder adapter seat 17 limits the swing amplitude of the milling cutter mechanism, and the size of the gap between the slide cylinder adapter seat 17 and the motor adapter plate 5 limits the swing range of the milling cutter mechanism.

[0047] Adjustment plates 21 are symmetrically fixedly arranged on the upper and lower sides of the motor fixing seat 4; there are multiple follow-up mechanisms, which are symmetrically arranged on the adjustment plate with the milling cutter 6 as the center; the follow-up mechanism located above the milling cutter 6 is correspondingly arranged on the adjustment plate located above the milling cutter 6, and the follow-up mechanism located below the milling cutter 6 is correspondingly arranged on the adjustment plate located below the milling cutter 6. A dust cover 24 is arranged above the linear guide 9 located above the milling cutter 6, and the dust cover plays a dustproof role.

[0048] The follower mechanism includes a universal ball bearing 7, a linear guide rail 9, a slide 8, and a screw A10. The slide 8 is fixedly arranged on the adjustment plate 21, and the linear guide rail 9 is matched and arranged in the slide 8; the universal ball bearing 7 is fixedly arranged at the front end of the linear guide rail 9, and the universal ball bearing 7 and the milling cutter 6 are located on the same side;

[0049] The screw rod A10 is disposed behind the linear guide rail 9 , and the front end of the screw rod A10 contacts the rear end of the linear guide rail 9 .

[0050] A fixed plate A12 corresponding to the position is arranged at the rear of the linear guide rail 9, and the fixed plate A12 is fixedly arranged on the adjustment plate 21; the rear end of the screw rod A10 passes through the fixed plate A12 and is matched with a nut A11, which is fixedly arranged on the fixed plate A12, and the position of the screw rod A is fixed by the matching and locking of the nut A and the screw rod A. After the screw rod A10 is fixed, the screw rod A10 supports the rear end of the linear guide rail 9, and the position of the linear guide rail 9 is limited. A fixed plate B22 is fixedly arranged on the adjustment plate 21, and the fixed plate B22 is located at the rear of the fixed plate A12; the fixing of the position of the screw rod A limits and determines the position of the linear guide rail 9, and then determines the position of the universal ball bearing 7. Because the universal ball bearing contacts the processing plane during processing, the position of the universal ball bearing determines the cutting depth of the milling cutter 6 on the processing plane, and the cutting amount of the milling cutter 6 is controlled.

[0051] When the cutting depth of the milling cutter 6 needs to be adjusted according to the actual processing situation, the user rotates the screw A. The rotation of the screw A will change its front and rear position relative to the nut A, thereby changing the position of the front end of the screw A, and then changing the position of the linear guide rail 9 and the universal ball bearing 7, thereby achieving the adjustment of the cutting depth of the milling cutter 6 during processing.

[0052] A tension spring 23 is arranged between the linear guide rail 9 and the fixed plate B22, one end of the tension spring is fixedly connected to the rear end of the linear guide rail 9, and the other end is fixedly connected to the fixed plate B22; when the follower milling cutter assembly of the present invention is working, the tension spring 23 is always in a stretched state, so that the rear end of the linear guide rail is always tightly pressed against the front end of the screw A, which ensures that the cutting depth of the milling cutter 6 remains unchanged when the follower milling cutter assembly of the present invention is working.

[0053] The working method of the follower milling cutter assembly of the present invention is as follows:

[0054] Adjustment of the cutting depth of the milling cutter 6: The cutting depth of the milling cutter 6 is adjusted according to the processing requirements of the workpiece to be processed, and the screw A10 is rotated to adjust the front and rear positions of the screw A10 relative to the adjustment plate 21, thereby adjusting the position of the linear slide rail located in front of the screw A10, thereby adjusting the position of the universal ball bearing 7 fixed to the front end of the linear slide rail 9; when the milling cutter 6 of the milling cutter mechanism 2 processes the plane, the universal ball bearing 7 contacts the processing plane, and then the cutting depth of the milling cutter 6 is determined by the position of the universal ball bearing 7, thereby adjusting the cutting depth of the milling cutter by adjusting the position of the universal ball bearing 7;

[0055] Adjustment of the cutting angle of the milling cutter 6: By adjusting the relative position of the screw rod B19 and the sleeve 18 along the front-back direction, the gap between the slide cylinder adapter 17 and the motor adapter plate 5 is adjusted, and then the cutting angle range of the milling cutter 6 is adjusted;

[0056] When the follower milling cutter assembly is working, the slide cylinder 15 of the milling cutter slide mechanism 1 is started, and the slide of the slide cylinder 15 moves forward, driving the milling cutter mechanism 2 to move forward until the universal ball bearing 7 of the follower mechanism presses against the plane to be processed, and the motor 3 is started to drive the milling cutter 6 to rotate to mill the plane to be processed; when the plane to be processed is uneven and tilted, the milling cutter mechanism will adjust its tilt angle to ensure the milling quality of the milling cutter on the plane to be processed.

[0057] The follow-up milling cutter assembly of the present invention can make adaptive follow-up changes following the plane conditions of the plane to be processed when performing small-scale plane processing, so as to ensure the milling effect and milling quality of the processed plane; the setting of the screw rod A can adjust the cutting depth of the milling cutter according to different processing requirements, so as to ensure that the cutting depth of the milling cutter remains unchanged during the processing; the setting of the screw rod B can adjust the gap between the motor adapter plate and the slide cylinder adapter plate, thereby allowing the milling cutter mechanism to tilt and rotate within a certain angle range. The larger the gap, the greater the rotation angle of the milling cutter in the vertical plane.

[0058] When performing small-scale processing on a plane, such as processing a weld, first make the weld position of the workpiece correspond to the position of the milling cutter and fix the workpiece. The slide cylinder drives the universal ball bearing of the milling cutter mechanism to press the workpiece's surface to be processed. When the surface to be processed is tilted, since the milling cutter mechanism is pressed on the surface to be processed, the universal ball bearing slides up and down along the surface to be processed for follow-up adjustment, so that the angle of the milling cutter can be adaptively adjusted as the surface to be processed changes, thereby ensuring the processing quality of the plane by the milling cutter.

[0059] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the scope of the technical solution of the present invention also belong to the protection scope of the present invention.
