Detailed implementation manners

[0034] In order to make the objectives, technical solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the specific embodiments of the present invention. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Refer to Figure 1-8, an embodiment of the present invention provides a cutting device for a chrome-plated rod, which includes an operating platform 12 and a driving unit installed on the operating platform 12. A cutting seat 11 is installed on one side of the operating platform 12. An assembly table 112 is slidably connected inside the cutting seat 11. An electric push rod 111 is installed on the upper surface of the cutting seat 11, and the telescopic end of the electric push rod 111 passes through the cutting seat 11 and is connected to the assembly table 112. A cutting machine 113 is installed under the assembly table 112. The driving unit can lock the rod body 131 and drive the rod body 131 along the horizontal direction. The driving unit includes a number of driving modules arranged in a circular shape at equal intervals. In this solution, 3 groups of driving modules are installed, and the 3 groups of driving modules are arranged in a circular shape at equal intervals. The center of the 3 groups of driving modules coincides with the center of the rod body 131 locked on the driving unit. Each driving module includes an assembly seat 13 and a number of rubber belt bodies 14. The assembly seat 13 can rotate and can displace outward in a direction perpendicular to the center line of the 3 groups of driving modules. A number of rubber belt bodies 14 are arranged in a circular shape on the assembly seat 13. The outer sides of the number of rubber belt bodies 14 are all concave and curved locking cavities 15 with different sizes. The sizes of the locking cavities 15 on the multiple rubber belt bodies 14 of each driving module can be set to different specifications. Each driving module includes rubber belt bodies 14 with locking cavities 15 of the same size. When locking a rod body 131 of a set size, first place the rod body 131 in the direction of the center line, then rotate the assembly seats 13 of a number of driving modules to make the rubber belt bodies 14 with locking cavities 15 of the same size face the rod body 131, and then move the assembly seats 13 in a direction perpendicular to the center line to bring the number of driving modules closer to each other, achieving a circular locking area that can lock the rod body 131. In this locking area, the rod body 131 can be locked and can be driven to move horizontally under the rotation of the rubber belt bodies 14. Thus, in the case where the layout of the device remains unchanged, it can meet the requirements of rod bodies 131 of various sizes and fully meet the driving displacement requirements of rod bodies 131 of various sizes.

[0036] Two assembly units 16 are installed oppositely on the upper surface of the operating platform 12. The assembly units 16 are arranged in a circular shape. The center of the assembly holes 17 of the assembly units 16 coincides with the center of a number of driving modules. A number of driving modules are installed between the two assembly units 16. The assembly seat 13 can rotate around the center line of a number of driving modules based on the assembly unit 16 and can displace in a direction perpendicular to the center line. Each driving module is connected to the two assembly units 16 through one assembly seat 13. The installation of the assembly seat 13 enables it to maintain a horizontal position with respect to the center lines of a number of driving modules and can rotate.

[0037] The driving module includes an orientation changing part, which is used to change the rotation amplitude of the assembly seat 13 on the assembly unit 16 and change the circumferential orientation of the assembly seat 13 based on the assembly unit 16. The orientation changing part can achieve the purpose of changing the shape of the assembly seat 13.

[0038] The azimuth changing part can displace the mounting seat 13 in the azimuth away from and approaching the rod body 131. During the azimuth displacement of the mounting seat 13 away from the rod body 131, the span between several driving modules can be expanded, enabling each mounting seat 13 to rotate without interfering with each other's movements. During the displacement of the mounting seat 13 approaching the rod body 131, the span of several driving modules can be shortened, thereby using the locking cavity 15 of the rubber belt body 14 of several driving modules to lock the rod body 131.

[0039] The azimuth changing part includes a coupling unit 18, a lead screw 120 and a displacement driving member. The coupling unit 18 is polygonal and is fixedly connected to the mounting seat 13. A constraint section 19 is arranged on the mounting unit 16, and a displacement section 191 and a rotating unit 192 are arranged at both ends of the constraint section 19. The displacement section 191 is arranged close to the center line of several driving modules. The coupling unit 18 can displace between the displacement section 191 and the rotating unit 192. The coupling unit 18 cannot rotate in the displacement section 191 but can rotate in the rotating unit 192; the lead screw 120 is rotatably arranged on the mounting seat 13, and the lead screw 120 is rotatably connected to the mounting seat 13 via a rotating rod 123; the displacement driving member is connected between the mounting unit 16 and the lead screw 120 and is used to drive the mounting seat 13 to displace in an azimuth of 90 degrees with respect to the center line. During the period when the rubber belt body 14 needs to be changed to fit rod bodies 131 of various sizes, the displacement driving member first displaces the coupling unit 18 from the displacement section 191 to the rotating unit 192, so that the coupling unit 18 can rotate in the rotating unit 192. Then, the mounting seat 13 is driven to rotate to the working azimuth via the coupling unit 18. After achieving the azimuth change, the displacement driving member displaces the coupling unit 18 back to the displacement section 191 to restrain the coupling unit 18 and prevent accidental rotation during work.

[0040] The displacement driving member is a slewing bearing 121. The slewing bearing 121 is rotatably connected to the mounting unit 16 via a rotating rod 122 and is threadedly connected to the lead screw 120. During the rotation of the slewing bearing 121, the threaded connection between the slewing bearing 121 and the lead screw 120 is in linkage, thereby driving the lead screw 120 and the mounting seat 13 to displace.

[0041] The assembly base 13 has ends a and b arranged horizontally. The ends a and b of the assembly base 13 are both provided with lead screws 120 and slewing bearings 121. The slewing bearings 121 at both ends of the assembly base 13 cooperate via a linkage unit. The linkage unit includes sprockets 125 installed on the slewing bearings 121 and a chain 126 connected between the two sprockets 125. Such an arrangement can ensure that when the operator rotates the slewing bearing 121, the sprockets 125 on the slewing bearing 121 rotate together, and the rotational movement is transmitted to the sprockets 125 on other slewing bearings 121 via the chain 126, thereby driving the other slewing bearings 121 to rotate together. Since the two slewing bearings 121 rotate together, the two slewing bearings 121 drive both ends of the assembly base 13 together, causing the assembly base 13 to move. And to make it more convenient to rotate the slewing bearing 121, a grip 124 is installed on the slewing bearing 121 at one end of the assembly base 13. Without external power, the operator can change the orientation of the assembly base 13 by himself.

[0042] A connection cavity 127 is arranged on the side of the assembly base 13. Two linkage rollers 129 are rotatably connected in the connection cavity 127. One of the two linkage rollers 129 is driven to move by a motor 128. A rubber belt body 14 is connected between the two linkage rollers 129. During the operation of the motor 128, one of the linkage rollers 129 is driven to rotate, thereby driving the rubber belt body 14 to move. The movement of the rubber belt body 14 can be used to drive the rod body 131.

[0043] To improve the cooperation ability and stability of the rubber belt bodies 14, magnetic attraction members 130 are installed on the rubber belt bodies 14 on both sides of the locking cavity 15. The magnetic attraction members 130 are made of a composite of bonded ferrite magnetic powder and synthetic rubber, and are soft, elastic and distortable magnets made by processes such as extrusion molding, calendering molding, and injection molding. In this solution, the magnetic attraction members 130 are in the shape of thin rods, and the rubber belt bodies 14 close to each other are adsorbed to each other via the magnetic attraction members 130. The magnetic attraction members 130 are arranged along the surface of the rubber belt body 14. When the rubber belt body 14 moves, the rubber belt bodies 14 can be tightly in contact via the magnetic attraction effect of the magnetic attraction members 130, thereby obtaining a stable and continuous locking wall, ensuring that the pressure and contact area borne by the rod body 131 during the stroke are balanced, making the locking more stable, and increasing the displacement friction force borne by the rod body 131.

[0044] The implementation method is specifically as follows: At the beginning, the operator rotates the slewing bearing 121 through the grip 124, causing several driving modules to displace towards a position farther from the center line. In this way, the connecting units 18 at both ends of the mounting seat 13 displace from the displacement section 191 to the rotating unit 192, obtaining sufficient movement range for subsequent rotation actions. According to the size of the rod body 131 to be cut, the operator selects a suitable rubber belt body 14 and rotates the mounting seat 13 to the required position in the rotating unit 192, ensuring that the locking cavity 15 of the rubber belt body 14 that meets the conditions can touch the rod body 131. After achieving the variation purpose, the operator rotates the slewing bearing 121 through the grip 124 again, displaces the connecting unit 18 to the displacement section 191, and restrains it, ensuring the stable position of the mounting seat 13 during subsequent displacement cutting and avoiding accidental rotation. The rod body 131 to be cut sequentially passes through the mounting holes 17 of the two mounting units 16 on the working platform 12, aligning the rod body 131 with the center line. Then, the operator rotates the slewing bearing 121 through the grip 124, causing the rubber belt bodies 14 of several driving modules to firmly lock the rod body 131 through the cooperation of the locking cavities 15 that meet the requirements. The magnetic components 130 on the rubber belt bodies 14 act, and the mutually approaching rubber belt bodies 14 tightly touch through the magnetic attraction effect, thereby obtaining a stable and continuous locking wall to ensure the firm locking of the rod body 131. Start the motor 128 to drive the driving roller 129 to rotate, causing the engagement between the rubber belt body 14 and the driving roller 129 to drive the rubber belt body 14 to move. The movement of the rubber belt body 14 drives the locked rod body 131 to move, thereby achieving the purpose of delivering the rod body 131. During the variation according to rod bodies 131 of other sizes, the operator can conveniently make variations to meet the requirements of rod bodies 131 of other sizes through the above actions to lock, displace, and cut the rod body 131. When the rod body 131 moves below the cutting machine 113, start the electric push rod 111 and the cutting machine 113. The telescopic end of the electric push rod 111 drives the mounting table 112 to move, enabling the cutting machine 113 to cut the rod body 131, and then move upward and reset, waiting for the continuous feeding of the rod body 131 to cut the rod body 131 in segments.
