Description

Technical Field

[0001] The present invention relates to the field of intelligent processing and manufacturing, and particularly relates to an automatic cutting device for processing special-shaped fasteners. Background Art

[0002] Special-shaped fasteners refer to fasteners with special shapes or designs, which are used to meet the engineering requirements in specific applications. Different from ordinary standard fasteners, the design shapes, sizes or functions of special-shaped fasteners may be customized according to specific engineering requirements to ensure the best performance and reliability in special applications. Special-shaped fasteners can have non-standard head shapes, thread designs or overall structures to meet specific installation requirements or space limitations. Therefore, when processing special-shaped fasteners, conventional clamping is difficult to achieve stable clamping. Even if the clamping effect is achieved, there will be looseness due to the shape of the special-shaped fastener itself, resulting in unstable final cutting processing.

[0003] Therefore, an automatic cutting device for processing special-shaped fasteners is now developed to solve the above problems. Summary of the Invention

[0004] In order to overcome the disadvantages that when the existing device processes special-shaped fasteners, conventional clamping is difficult to achieve stable clamping, and even if the clamping effect is achieved, there will be looseness due to the shape of the special-shaped fastener itself, resulting in unstable final cutting processing, the present invention provides an automatic cutting device for processing special-shaped fasteners.

[0005] The technical implementation solution of the present invention is: an automatic cutting device for processing special-shaped fasteners, including a mounting base. Two symmetrically arranged lifting hydraulic cylinders are connected to the upper side of the left part of the mounting base. An installation frame is connected between the telescopic ends of the lifting hydraulic cylinders. A cutting assembly is installed on the installation frame. It further includes: a clamping mechanism, which is arranged on the mounting base and is used for adaptively clamping the special-shaped fastener; a rotating mechanism, which is arranged on the mounting base and is used to drive the clamping mechanism to move, so as to further clamp the special-shaped fastener.

[0006] Furthermore, the clamping mechanism includes an installation frame. Two of the installation frames are rotatably arranged in the middle of the mounting base. Rotating plates are rotatably connected to the installation frames. Twelve sliding members are slidably arranged between the adjacent installation frames and the rotating plates. Clamping members are slidably arranged on the sliding members. First springs are connected between the clamping members and the adjacent sliding members. Driving motors are installed on the lower sides of the installation frames through bolts. The output shafts of the driving motors are all arranged towards the left. Pulley assemblies are connected between the output shafts of the driving motors and the left sides of the adjacent rotating plates.

[0007] Furthermore, the rotation mechanism includes a first driving motor. Two first driving motors are connected to the front part of the mounting seat. Rotating discs are connected to the output shafts of the first driving motors. Defective gears are rotatably connected to the rotating discs. Three second springs are connected between each rotating disc and the adjacent defective gear. Straight gears are connected to the mounting frames, and the straight gears are meshed with the adjacent defective gears.

[0008] Furthermore, a feeding mechanism is further included. The feeding mechanism includes a feeding component. A feeding mechanism for automatically feeding special-shaped fasteners is connected to the upper side of the right part of the mounting seat. A second driving motor is connected to the upper side of the right part of the mounting seat by bolts. The output shaft of the second driving motor is connected to the feeding component. A lifting component is installed on the feeding component, and another feeding component is connected to the top of the lifting component.

[0009] Furthermore, a material ejecting mechanism is further included. The material ejecting mechanism includes a fixing plate. The fixing plate is connected to the mounting frame, and a top frame is connected to the fixing plate.

[0010] Furthermore, a collecting mechanism is further included. The collecting mechanism includes a collecting frame. The collecting frame is connected to the left part inside the mounting seat. Two symmetrically arranged front and rear sleeves are connected to the bottom inside the collecting frame. A buffer seat is slidably connected between the sleeves, and two third springs are connected between the buffer seat and the sleeves.

[0011] Furthermore, a protection mechanism is further included. The protection mechanism includes a first protection frame. The first protection frame is connected to the top of the mounting seat. A second protection frame is connected to the top of the mounting seat, and the second protection frame is located on the left side of the first protection frame.

[0012] Furthermore, the cutting component includes a connecting seat and a cutting wire. Connecting seats are connected to the lower sides of the front and rear parts of the mounting frame, and a cutting wire is connected between the connecting seats.

[0013] Furthermore, the included angle between the sliding members is 30 degrees, and they are evenly distributed in the cylindrical space between the mounting frame and the rotating plate.

[0014] Furthermore, the pulley assembly is composed of a pulley and a transmission belt.

[0015] By adopting the above technical solutions, the present invention has the following advantages:

[0016] 1. The present invention relies on the output shaft of the driving motor to drive the rotating plate to rotate, so that the twenty-four sliding members all slide inwards and approach each other, enabling the clamping members to contact the protrusions or depressions on the special-shaped fasteners, and achieving comprehensive clamping and fixing of the special-shaped fasteners in a small-angle uniform distribution manner, so that the special-shaped fasteners remain stable during cutting processing.

[0017] 2. As the clamping members complete the clamping of the special-shaped fasteners, there may still be an unstable situation at this time. This situation may be due to the mismatch between the clamping members and the special-shaped parts of the special-shaped fasteners. At this time, the first driving motor can be started to control the two mounting frames to rotate towards each other, further strengthening the clamping and fixing effect of the clamping members on the special-shaped fasteners.

[0018] 3. As the lifting hydraulic cylinder drives the mounting frame to move and completes the cutting process of the special-shaped fasteners, there may be an incomplete cutting situation. At this time, the special-shaped fasteners will be adhered. As the lifting hydraulic cylinder drives the mounting frame to move upward and reset, the top frame will move upward synchronously, so as to perform a secondary cutting process on the adhered part of the special-shaped fasteners.

Detailed implementation manners

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0030] An automatic cutting device for processing special-shaped fasteners, as Figure 1 and Figure 2 shown, includes a mounting base 1. Two symmetrically arranged front and rear lifting hydraulic cylinders 2 are connected to the upper side of the left part of the mounting base 1. The telescopic ends of the lifting hydraulic cylinders 2 are all upwardly oriented. A mounting frame 3 is connected between the telescopic ends of the lifting hydraulic cylinders 2. A cutting assembly 4 for cutting the fasteners is mounted on the mounting frame 3. The cutting assembly 4 includes a connecting seat and a cutting wire. Connecting seats are connected to the lower sides of the front and rear parts of the mounting frame 3, and a cutting wire is connected between the connecting seats. It further includes: a clamping mechanism 5, which is arranged on the mounting base 1 and is used for adaptively clamping the special-shaped fasteners; a rotating mechanism 6, which is arranged on the mounting base 1 and is used to drive the clamping mechanism 5 to move, so as to further clamp the special-shaped fasteners.

[0031] It should be noted that when processing special-shaped fasteners, this device can be used for auxiliary operations. Different from conventional fasteners, due to their shape, it is difficult to firmly clamp special-shaped fasteners with conventional clamping methods. When using this device, place the special-shaped fastener in the clamping mechanism 5, then control the operation of the clamping mechanism 5. Through the clamping mechanism 5, perform all-round adaptive clamping on the special-shaped part. After completion, start the rotating mechanism 6 to make the clamping mechanisms 5 rotate towards each other in sequence, further lock and fix the special-shaped fastener, making the placement of the special-shaped fastener more stable and improving the stability of the cutting operation. Then, control the lifting hydraulic cylinder 2 to drive the mounting frame 3 to move, and rely on the cutting assembly 4 to perform cutting processing on the special-shaped fastener.

[0032] As Figure 1 、 Figure 3 and Figure 4 shown, the clamping mechanism 5 includes a mounting frame 51. Two mounting frames 51 are rotatably arranged in the middle of the mounting seat 1. Rotating plates 52 are rotatably connected to the mounting frames 51. Twelve sliding members 53 are slidably arranged between adjacent mounting frames 51 and rotating plates 52. The included angle between the sliding members 53 is 30 degrees and they are evenly distributed in the cylindrical space between the mounting frame 51 and the rotating plate 52. Clamping members 54 for clamping and limiting the special-shaped fastener are slidably arranged on the sliding members 53. First springs 55 are connected between the clamping members 54 and the adjacent sliding members 53. Drive motors 57 are bolted to the lower sides of the mounting frames 51. The output shafts of the drive motors 57 are all oriented to the left. Belt pulley assemblies 56 are connected between the output shafts of the drive motors 57 and the left sides of the adjacent rotating plates 52. The belt pulley assemblies 56 are composed of belt pulleys and transmission belts.

[0033] It should be noted that when cutting the special-shaped fastener, place the special-shaped fastener through the centers of the two mounting frames 51. Then start the drive motor 57. The rotation of the output shaft of the drive motor 57 will drive the pulley assembly 56 to operate. The operation of the pulley assembly 56 will drive the corresponding rotating plate 52 to rotate. As the rotating plates 52 all start to rotate, the corresponding sliding members 53 will all slide inwards and approach each other, so that the inner ends of the clamping members 54 all contact the surface of the special-shaped fastener. Due to the shape characteristics of the special-shaped fastener, the clamping members 54 will all slide to varying degrees due to contact with the special-shaped fastener. Correspondingly, the first springs 55 will all produce varying degrees of compressive deformation, thus achieving the effect of all-round fixed clamping, adapting to each convex or concave part of the special-shaped fastener. After cutting is completed, control the output shaft of the drive motor 57 to rotate in the reverse direction, so that the pulley assembly 56 drives the rotating plate 52 to rotate in the reverse direction, so that the sliding members 53 all slide outwards and return to their original positions, and the clamping members 54 no longer contact the special-shaped fastener, and the first springs 55 all return to their initial states. The operator can push the cut fastener to the left to perform subsequent re-cutting processing, or take out the special-shaped fastener.

[0034] As Figure 1 and Figure 5 As shown, the rotating mechanism 6 includes a first drive motor 61. Two first drive motors 61 are connected to the front part of the mounting seat 1. Rotating disks 62 are connected to the output shafts of the first drive motors 61. Defective gears 63 are rotatably connected to the rotating disks 62. Three second springs 64 are connected between the rotating disks 62 and the adjacent defective gears 63. Straight gears 65 are connected to the mounting frames 51. The straight gears 65 are all meshed with the adjacent defective gears 63.

[0035] It should be noted that as the clamping member 54 completes the clamping of the special-shaped fastener, there may still be an unstable situation at this time. This situation may be due to the inadaptable contact between the clamping member 54 and the special-shaped part of the special-shaped fastener. At this time, the first drive motor 61 can be started to control the two mounting frames 51 to rotate towards each other. The rotation of the output shaft of the first drive motor 61 will drive the rotating disk 62 to rotate, so that the defective gear 63 and the second spring 64 rotate together, and then the straight gear 65 drives the corresponding mounting frame 51 to rotate until the loose clamping member 54 is completely and firmly attached to the special-shaped fastener. At this time, the mounting frame 51 cannot continue to rotate due to the clamping member 54, and the straight gear 65 is in a fixed state. The continuous rotation of the output shaft of the first drive motor 61 will drive the rotating disk 62 to continue to rotate, so that the second springs 64 are all compressed by force, pressing and limiting the position of the defective gear 63, and then making the contact between the defective gear 63 and the straight gear 65 closer, avoiding loosening between the defective gear 63 and the straight gear 65, and further strengthening the clamping and fixing effect of the clamping member 54 on the special-shaped fastener. Embodiment

[0036] Based on Embodiment 1, as Figure 1 and Figure 6 shown, it further includes a feeding mechanism 7. The feeding mechanism 7 includes a feeding component 71. On the upper side of the right part of the mounting base 1, there is a feeding mechanism connected for automatically feeding the special-shaped fasteners. On the upper side of the right part of the mounting base 1, a second driving motor 72 is connected by bolts. The output shaft of the second driving motor 72 is set to face backward. The output shaft of the second driving motor 72 is connected to the feeding component 71. The feeding component 71 is equipped with a lifting component 73, and the top of the lifting component 73 is connected to another feeding component 71.

[0037] It should be noted that when feeding the special-shaped fasteners, the distance between the feeding components 71 can be adjusted by controlling the lifting component 73 according to the specifications of the special-shaped fasteners, so that the special-shaped fasteners can be properly placed. After the placement is completed, the second driving motor 72 is started. The rotation of the output shaft of the second driving motor 72 will drive the lower feeding component 71 to operate, and with the cooperation of the upper feeding component 71, the special-shaped fasteners can be automatically fed.

[0038] As Figure 1 and Figure 7 shown, it further includes a pushing mechanism 8. The pushing mechanism 8 includes a fixing plate 81. The fixing plate 81 is connected to the mounting frame 3, and a pushing frame 82 for pushing and perfecting the cutting of the cut special-shaped fasteners is connected to the fixing plate 81.

[0039] It should be noted that as the lifting hydraulic cylinder 2 drives the mounting frame 3 to move, after the cutting process of the special-shaped fasteners is completed, there may be an incomplete cutting situation. At this time, the special-shaped fasteners may be adhered. As the lifting hydraulic cylinder 2 drives the mounting frame 3 to move upward and reset, the pushing frame 82 will move upward synchronously, thereby performing a secondary cutting process on the adhered part of the special-shaped fasteners.

[0040] As Figure 1 and Figure 8 shown, it further includes a collecting mechanism 9. The collecting mechanism 9 includes a collecting frame 91. The collecting frame 91 is connected to the left part inside the mounting base 1. Two symmetrically arranged sleeves 93 are connected to the bottom inside the collecting frame 91. A buffer seat 92 is slidably connected between the sleeves 93, and two third springs 94 are connected between the buffer seat 92 and the sleeves 93.

[0041] It should be noted that the cut special-shaped fasteners will fall downward onto the buffer seat 92 and impact the buffer seat 92, causing the buffer seat 92 to slide downward along the sleeves 93, and the third springs 94 are all compressed by the force, thereby completing the collection of the special-shaped fasteners and also providing a certain protection for the fasteners.

[0042] AsFigure 1 and Figure 9 As shown in Figure 9 , it further includes a protection mechanism 10. The protection mechanism 10 includes a first protection frame 101. The top of the mounting base 1 is connected to the first protection frame 101. The top of the mounting base 1 is also connected to a second protection frame 102, and the second protection frame 102 is located on the left side of the first protection frame 101.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
