Abstract
Description
Technical Field
[0001] This utility model relates to the field of thread protection sleeves, specifically an anchoring machine for the outer bushing of an external thread protector. Background Technology
[0002] The external thread protector consists of a plastic internal thread cap and a metal outer bushing that is fastened to the outside of the internal thread cap. The metal outer bushing increases the overall structural strength.
[0003] After the outer bushing is attached to the inner threaded cap, the operator needs to use a steel awl and a hammer to tap several indentations into the outer bushing. The deformation caused by the indentations will penetrate into the inner threaded cap, thereby increasing the firmness of the connection between the two.
[0004] All of the above operations are performed manually by the operators, resulting in low work efficiency. Furthermore, when using a hammer to strike the steel cone to anchor the outer bushing, the hammer may not be properly controlled and could easily hit the operator's hand holding the steel cone, posing a certain safety hazard. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing an external thread protector bushing anchoring machine. This machine achieves higher anchoring efficiency through mechanization, and during the anchoring operation, the operator's hands do not come into contact with the equipment or the external thread protector, making it safer and more reliable.
[0006] The technical solution of this utility model is: an external thread protector bushing anchoring machine, including a frame, a rotating shaft rotatably connected to the top of the frame, a rotating drive mechanism and a turntable respectively provided at both ends of the rotating shaft, an eccentric shaft provided on the outer side of the turntable, and a connecting rod rotatably connected through the eccentric shaft, a slide seat provided below the turntable, a guide rod slidably connected vertically on the slide seat, the top of the guide rod rotatably connected to the end of the connecting rod, a support plate provided at the bottom of the guide shaft, and an anchoring needle connected downward to the support plate;
[0007] The frame has a mounting plate in the middle. The outer side of the mounting plate, below the anchor pin, has an arc-shaped support plate and a vertical through groove. The lower end of the mounting plate is vertically slidably connected to a motor base. The mounting plate has an elastic support mechanism for elastically supporting the motor base downwards. The motor base has a first drive motor. The shaft of the first drive motor passes through the vertical through groove and is connected to a friction transmission roller. The outer edge of the friction transmission roller has an outer chamfer.
[0008] Preferably, the rotary drive mechanism includes an inertial flywheel connected to the other end of the rotating shaft, and a second drive motor mounted on the frame. A drive wheel is connected to the output shaft of the second drive motor, and the drive wheel and the inertial flywheel are connected by belt drive.
[0009] Preferably, the elastic support mechanism includes a limiting block fixedly connected to the mounting plate above the motor base, and a set of support springs elastically supported between the limiting block and the motor base.
[0010] Preferably, both the limiting block and the motor base are provided with limiting posts that extend into the end of the support spring.
[0011] Preferably, both sides of the mounting plate are provided with vertically arranged elongated bolt grooves, and the mounting plate is fixed to the frame by bolts inserted into the elongated bolt grooves.
[0012] Compared with the prior art, this utility model has the following advantages: the anchoring efficiency is higher through mechanization, and the operator's hands do not come into contact with the equipment and external thread protector during the anchoring operation, making it safer and more reliable.
[0013] In addition, by driving the inertial flywheel to rotate through the second drive motor, and then driving the guide rod to move up and down in conjunction with the inertial flywheel, turntable and connecting rod, the anchoring force when the guide rod drives the anchoring pin to move down can be increased, and the anchoring effect is better.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1
[0020] like Figures 1 to 4An external thread protector bushing anchoring machine includes a frame 11, with a rotating shaft rotatably connected to the top of the frame 11. A rotating drive mechanism and a turntable 2 are respectively provided at both ends of the rotating shaft.
[0021] The rotary drive mechanism specifically includes an inertial flywheel 1 connected to the end of the rotating shaft, and a second drive motor 15 mounted on the frame 11. A drive wheel 16 is connected to the output shaft of the second drive motor 15, and the drive wheel 16 and the inertial flywheel 1 are connected by a belt 14.
[0022] An eccentric shaft is provided on the outer side of the turntable 2, and one end of the connecting rod 3 is rotatably connected through the eccentric shaft. A slide 5 is provided below the turntable 2, and a guide rod 4 is slidably connected vertically on the slide 5. The top of the guide rod 4 is rotatably connected to the other end of the connecting rod 3. A support plate 6 is provided at the bottom of the guide shaft, and an anchoring pin 7 is connected downward to the support plate 6.
[0023] The frame 11 has a mounting plate 9 in the middle. The outer side of the mounting plate 9 is provided with an arc-shaped support plate 8 and a vertical through groove below the anchor pin 7. The lower end of the mounting plate 9 is vertically slidably connected to a motor base 19. The mounting plate 9 is provided with an elastic support mechanism for elastically supporting the motor base 19 downwards.
[0024] The elastic support mechanism includes a limiting block 17 fixedly connected to the mounting plate 9 above the motor base 19, and a set of support springs 18 elastically supported between the limiting block 17 and the motor base 19. To ensure the assembly stability of the support springs 18, limiting posts extending into the ends of the support springs 18 are provided on both the limiting block 17 and the motor base 19.
[0025] The motor base 19 is equipped with a first drive motor 20. The shaft of the first drive motor 20 passes through the vertical through groove and is connected to the friction transmission roller 10. The outer edge of the friction transmission roller 10 is provided with an outer chamfer to form a conical structure, so that the external thread protector 23 can be fastened to the outside of the friction transmission roller 10.
[0026] Working principle:
[0027] The rotary drive mechanism drives the turntable 2 to rotate, and the eccentric shaft on the turntable 2 drives the guide rod 4 to slide vertically back and forth along the slide block 5 through the connecting rod 3, thereby driving the anchoring needle 7 to move up and down back and forth.
[0028] During operation, the metal outer bushing 21 is first fastened to the outside of the inner thread cover 22 to form an external thread protector 23. Then, the external thread protector 23 is fastened to the arc-shaped support plate 8 and the friction transmission roller 10, so that the upper end of the inner circumferential surface of the external thread protector 23 contacts the arc-shaped support plate 8 and the lower end contacts the bottom of the friction transmission roller 10, thereby driving the external thread protector 23 to rotate through the friction transmission roller 10.
[0029] When the anchoring pin 7 moves downward, it impacts the outer bushing 21, causing the outer bushing 21 to deform and embed into the plastic inner thread cap 22. When the anchoring pin 7 moves upward, the first drive motor 20 and the friction roller drive the outer thread protector 23 to rotate at a certain angle, thereby anchoring the anchoring pin 7 to the next position of the outer thread protector 23 when it moves downward again. The above steps are repeated to anchor the outer bushing 21 for one revolution. The first drive motor 20 is preferably a stepper motor, which makes it easier to control the rotation angle of the outer thread protector 23.
[0030] Mechanized anchoring is more efficient, and the operator's hands do not come into contact with the equipment or the external thread protector 23 during the anchoring operation, making it safer and more reliable.
[0031] In addition, the second drive motor 15 drives the inertial flywheel 1 to rotate, and the inertial flywheel 1, turntable 2 and connecting rod 3 drive the guide rod 4 to move up and down reciprocally, which can increase the anchoring force when the guide rod 4 drives the anchoring needle 7 to move down. Example 2
[0032] This embodiment is a further optimization based on the above embodiments;
[0033] In this embodiment, the mounting plate 9 and the frame 11 are installed using a sliding connection method, specifically:
[0034] Both sides of the mounting plate 9 are provided with vertically arranged elongated bolt grooves 13, and the mounting plate 9 is fixed to the frame 11 by bolts 12 inserted into the elongated bolt grooves 13. The height of the mounting plate 9 can be adjusted by loosening the bolts 12.
[0035] By sliding the mounting plate 9 to the frame 11, the distance between the anchor pin 7 and the arc-shaped support plate 8 can be finely adjusted, thereby adjusting the anchoring depth of the anchor pin 7 impacting the external thread protector 23, making it more reasonable and convenient to use.
[0036] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
