Abstract
Description
Technical Field
[0001] This utility model relates to the field of thread protector processing technology, specifically to an internal thread protector inner bushing anchoring machine. Background Technology
[0002] The internal thread protector consists of a plastic external thread cap and a metal inner sleeve nested inside the inner wall of the thread cap. The metal inner sleeve increases the overall structural strength.
[0003] After the inner liner is embedded into the outer threaded cover, the operator needs to use a steel awl and a hammer to tap several indentations on the inner wall of the inner liner. The deformation produced by the indentations will be inserted into the inner wall of the outer threaded cover, thereby increasing the connection between the two. Then, the outer thread is milled on the outer circumference of the outer threaded cover using a milling machine.
[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 inner 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 invention is to address the shortcomings of existing technologies by providing an internal thread protector bushing anchoring machine. This machine achieves higher anchoring efficiency through mechanization, and ensures greater safety and reliability by keeping the operator's hands away from the anchoring needle during the anchoring operation.
[0006] The technical solution of this utility model is: an internal thread protector inner 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;
[0007] Below the turntable is a slide block, and a guide rod is vertically slidably connected to the slide block. The top of the guide rod is rotatably connected to the end of the connecting rod. A support plate is provided at the bottom of the guide rod, and an anchoring pin is connected downward to the support plate.
[0008] The frame has L-shaped support arms symmetrically connected to both sides of the anchor pin in the middle. The outer edge of the lateral end of each L-shaped support arm is rotatably connected to a friction roller shaft through a connecting block. The two friction roller shafts are arranged in parallel and distributed on both sides below the anchor pin.
[0009] Preferably, the rotary drive mechanism includes an inertial flywheel connected to the other end of the rotating shaft, and a drive motor mounted on the frame for driving the inertial flywheel.
[0010] Preferably, the longitudinal end of the L-shaped support arm is provided with a long strip bolt groove, and the L-shaped support arm is slidably connected to the frame by bolts inserted into the long strip bolt groove.
[0011] Preferably, the outer ends of both friction roller shafts are connected to sprockets via rotating shafts, the two sprockets are connected by chain drive, and a crank is connected to the outer side of one of the sprockets.
[0012] Preferably, the top of the anchor pin is detachably connected to the support plate by bolts.
[0013] Compared with the prior art, this utility model has the following advantages:
[0014] This invention achieves higher anchoring efficiency through mechanization, and the operator's hands are kept away from the anchoring needle during the anchoring operation, making it safer and more reliable.
[0015] By rotating the crank handle, both friction roller shafts can be driven to rotate simultaneously, thereby improving the stability of the friction-driven internal thread protector's rotation. This makes it more flexible and convenient to use, and keeps the user's hands further away from the equipment, further enhancing safety.
[0016] The L-shaped support arm is lockably slidably connected to the frame, and the height of the L-shaped support arm can be adjusted, thereby adjusting the height difference between the friction roller shaft and the bottom of the anchoring pin, and thus adjusting the anchoring depth.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1
[0022] like Figure 1 An internal thread protector inner bushing anchoring machine includes a frame 13. A rotating shaft is rotatably connected to the top of the frame 13. A rotating drive mechanism and a turntable 2 are respectively provided at both ends of the rotating shaft. An eccentric shaft is provided on the outer side of the turntable 2, and a connecting rod 3 is rotatably connected through the eccentric shaft.
[0023] The rotary drive mechanism includes an inertial flywheel 1 connected to the other end of the rotating shaft, and a drive motor 14 mounted on the frame 13 for driving the inertial flywheel 1. A pulley is connected to the output shaft of the drive motor 14, and the pulley drives the inertial flywheel 1 to rotate via a belt.
[0024] Below the turntable 2 is a slide block 5, on which a guide rod 4 is vertically slidably connected. The top of the guide rod 4 is rotatably connected to the end of the connecting rod 3. A support plate 6 is provided at the bottom of the guide rod, and an anchoring pin 7 is connected downward to the support plate 6.
[0025] The frame 13 has L-shaped support arms 10 symmetrically connected to both sides of the anchor pin 7 in the middle. The outer edge of the lateral end 10 of each L-shaped support arm is rotatably connected to a friction roller shaft 12 through a connecting block 11. The two friction roller shafts 12 are arranged in parallel and distributed on both sides below the anchor pin 7.
[0026] Working principle: such as Figure 2 When in use, first fasten the threaded cap embedded in the inner liner to the outside of the support plate 6 and the anchor pin 7, and support it through the two friction roller shafts 12. Then start the drive motor 14 to drive the turntable 2 to rotate. The eccentric shaft on the turntable 2 drives the guide rod 4 to slide vertically along the slide block 5 through the connecting rod 3, thereby driving the anchor pin 7 to move up and down back and forth.
[0027] Meanwhile, as the anchoring pin 7 moves downward, it impacts the inner liner to create a dent, anchoring itself to the inner wall of the external threaded sleeve. When the anchoring pin 7 moves upward, the operator slightly rotates the external threaded sleeve at a certain angle to prepare for anchoring at the next position. This reciprocating operation anchors the inner liner for one revolution, increasing the strength of the connection. The mechanized anchoring method is more efficient, and the operator's hands are kept away from the anchoring pin 7 during the anchoring operation, making it safer and more reliable. Example 2
[0028] This embodiment is a further optimization based on the above embodiment, specifically:
[0029] like Figure 3 The outer ends of the two friction roller shafts 12 are connected to sprockets 16 via rotating shafts. The two sprockets 16 are connected by chain drive, and a crank handle 15 is connected to the outer side of one of the sprockets 16.
[0030] In use, rotating the crank handle 15 can simultaneously drive the two friction roller shafts 12 to rotate, thereby improving the stability of the rotation of the friction drive internal thread protector 18, making it more flexible and convenient to use, and keeping the user's hands further away from the equipment, thus further improving safety. Example 3
[0031] This embodiment is a further optimization based on the above embodiment, specifically:
[0032] like Figure 1 and Figure 2 The longitudinal end 8 of the L-shaped support arm is provided with a long bolt groove 17, and the L-shaped support arm 10 is slidably connected to the frame 13 by bolts inserted into the long bolt groove 17. This design can adjust the height of the L-shaped support arm 10, thereby adjusting the height difference between the friction roller shaft 12 and the bottom of the anchoring pin 7, and thus adjusting the anchoring depth.
[0033] The top of the anchor pin 7 is detachably connected to the support plate 6 by bolts. This design facilitates the disassembly of the anchor pin 7 for grinding or replacement, making maintenance more convenient.
[0034] 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.
