Description

Technical Field

[0001] The utility model relates to the field of screw machines, in particular to a screw machine for a circuit breaker base and a contact seat. Background Art

[0002] In the field of electrical equipment manufacturing, the connection and tightening of the circuit breaker base and the contact seat is an important link. The traditional screw tightening work of the circuit breaker base and the contact seat is usually done manually, which has many shortcomings. The screw machine proposed in Chinese utility model patent application number: CN202120726523.X includes a console, a machine table, and a servo motor. The upper outer surface of the console is provided with a horizontal bubble, the lower outer surface of the console is provided with an adjustment sleeve, the lower end of the adjustment sleeve is provided with an adjustment column, the outer surface of the adjustment column is provided with an adjustment ring, the lower end of the adjustment ring is provided with a support foot, the interior of the support foot is provided with an annular groove, the outer surface of the adjustment column is provided with a connecting ring, the outer surface of the servo motor is provided with a through hole, the inner wall of the servo motor is provided with a mounting shell, and the outer surface of one side of the mounting shell is provided with a heat conducting plate.

[0003] However, the existing screw machines have the following shortcomings during use. First, manual operation is inefficient and it is difficult to meet the requirements of modern production for efficiency. Workers need to tighten the screws one by one. The operation process is cumbersome and consumes a lot of time and energy, resulting in low production efficiency. Secondly, the quality of manually tightened screws is difficult to guarantee. Due to the limitations of manual operation, it is difficult to ensure that each screw is tightened evenly and firmly, and it is easy to have problems such as loose tightening of screws or inaccurate positioning, which affects the quality and performance of the product. Furthermore, manual operation has certain safety risks. Workers are prone to fatigue and negligence during long-term repetitive operations, which can lead to safety accidents such as hand injuries.

[0004] Furthermore, traditional screw machines lack flexibility and adaptability. Manual operation makes it difficult to quickly adjust the tightening position and force for different specifications of circuit breaker bases and contact blocks, making it difficult to meet diverse production needs.

[0005] Traditional screw machines often fail to accurately position the contact base, causing it to deviate during the screw tightening process, impacting product quality. Stability is also insufficient. Without an effective fixing device, the contact base is prone to shaking or shifting during processing, resulting in suboptimal screw tightening or even loosening. Inaccurate positioning and unstable fixation often require rework and adjustments, significantly increasing operation time and reducing production efficiency. Therefore, we have addressed this issue by developing a screw machine for circuit breaker bases and contact bases. Utility Model Content

[0015] In the solution of the present invention: the various mechanisms of the screw machine of the present invention work together to automatically complete the screw tightening work of the circuit breaker base and the contact seat, which greatly improves production efficiency compared to manual operation. The X-axis horizontal movement mechanism and the Y-axis up and down movement mechanism can quickly and accurately move the screw drill bit to the specified position, reducing operation time.

The side positioning rods and positioning hooks can define the position of the contact base from multiple directions, further improving the contact base's positioning accuracy.

[0019] The positioning hook and the L-shaped hook frame below effectively secure the contact base, preventing it from shaking or shifting during processing, thereby ensuring the stability of screw tightening. Accurate positioning and stable fixation can reduce rework and adjustments caused by contact base position deviation, improve screw tightening efficiency, and thus enhance the efficiency of the entire production process.

The outer surface of the X-axis screw rod 702 is covered with an X-axis horizontal movement screw rod sleeve 703. The X-axis horizontal movement screw rod sleeve 703 is connected to the Y-axis housing 603.

[0040] A parts storage cabinet 101 is provided below the screw machine workbench 1 , a support rod 102 is provided below the parts storage cabinet 101 , and a buffer pad 103 is provided below the support rod 102 .

[0041] Working principle of the screw machine for the circuit breaker base and contact base: Screw machine positioning mechanism 3: The contact base is placed on the contact base positioning groove surface 302 of the contact base mounting frame 301. The side positioning rod 303 and positioning hook 304 define the position of the contact base, and the L-shaped hook frame 305 below further secures the contact base, ensuring its stability during processing.

[0042] Drill bit tightening mechanism 4: The drill bit servo motor 403 rotates the drill bit connecting shaft 402, thereby rotating the drill bit 401. Drill bit 401 is used to tighten the screws on the circuit breaker base and contact base. Drill bit Y-axis vertical movement mechanism 6: The Y-axis vertical movement pneumatic cylinder 602 drives the Y-axis vertical movement telescopic rod 601 to move up and down. The outer surface of the telescopic rod is equipped with a Y-axis housing 603 for protection and guidance.

[0043] The drill bit mounting position adjustment structure 5 allows the drill bit 401 to be adjusted within the drill bit mounting sliding slot 501 as needed and secured via the drill bit mounting hole 502. The drill bit X-axis horizontal movement mechanism 7: The X-axis servo motor 701 drives the X-axis screw 702 to rotate, causing the X-axis horizontal movement screw sleeve 703, which is sleeved on the outer surface of the X-axis screw 702, to move horizontally along the X-axis.

[0044] The X-axis horizontal screw shaft sleeve 703 is connected to the Y-axis housing 603, thereby driving the entire screw drill tightening mechanism 4 and the Y-axis up and down moving mechanism to move horizontally in the X-axis direction.

[0045] Overall working process: First, place the circuit breaker base and the contact seat in the screw machine positioning mechanism 3 on the screw machine workbench 1 for fixation and positioning.

[0046] Then, the X-axis horizontal movement mechanism and the Y-axis up-and-down movement mechanism work together to move the screw drill bit 401 to the position where the screw needs to be tightened. Finally, the screw drill bit tightening mechanism 4 is started, and the screw drill bit 401 rotates to tighten the screw on the circuit breaker base and the contact seat.

[0047] Parts storage cabinet 101 and support structure: The parts storage cabinet 101 below the screw machine workbench 1 is used to store screws and other parts for easy access. The support rod 102 below the parts storage cabinet 101 is used to support the entire equipment. The buffer pad 103 below the support rod 102 can reduce the vibration and noise generated by the operation of the equipment.

[0048] Example 2: A screw machine for securing a circuit breaker base and contact base. When tightening the screws between the circuit breaker base and contact base, the contact base is placed within the contact base positioning groove 302 of the contact base mounting frame 301. The contact base positioning groove 302 measures 20 cm long, 10 cm wide, and 5 cm deep, effectively accommodating the contact base. A positioning rod 303 on the side of the contact base positioning groove 302 is 15 cm long and 1 cm in diameter, providing preliminary positioning for the contact base. A positioning hook 304 on the side of the positioning rod 303, measuring 8 cm long and 3 cm wide, and an L-shaped hook 305 below, measuring 10 cm long and 5 cm wide, work together to securely secure the contact base.

[0049] Start the screw machine, the X-axis servo motor 701 has a power of 2kW, driving the X-axis screw rod 702 to rotate. The diameter of the X-axis screw rod 702 is 10mm and the pitch is 5mm. The X-axis horizontal moving screw rod sleeve 703 on the outer surface of the screw rod moves accordingly, thereby driving the Y-axis housing 603 connected to it to move horizontally in the X-axis direction.

[0050] After moving to the designated position, the Y-axis vertical movement pneumatic cylinder 602, operating at a pressure of 5 MPa, pushes the Y-axis vertical movement telescopic rod 601 up and down. The maximum travel of the Y-axis vertical movement telescopic rod 601 is 20 cm. The drill bit 401 is installed in the drill bit mounting slide slot 501 at the lower end of the Y-axis vertical movement telescopic rod 601 and secured via the drill bit mounting hole 502. The drill bit mounting hole 502 has a diameter of 6 mm, and the drill bit 401 has a diameter of 5 mm. The drill bit is connected to the rotating shaft 402, driving the drill bit 401 to rotate, tightening the screws on the circuit breaker base and contact seat. After the operation is completed, the processed parts are placed in the parts storage cabinet 101 below the screw machine workbench 1. The parts storage cabinet 101 is 50 cm long, 40 cm wide, and 30 cm high. The support rod 102 below the parts storage cabinet 101 is 30 cm long and 3 cm in diameter. The buffer pad 103 below the support rod 102 is 10 cm long, 10 cm wide and 2 cm thick, which can play a role in buffering and shock absorption.

[0051] Example 3: A screw machine for securing a circuit breaker base and contact base. The contact base is placed into the contact base positioning groove 302 of the contact base mounting frame 301. The groove 302 is 20 cm long, 10 cm wide, and 5 cm deep, fully meeting the contact base's placement requirements. A positioning rod 303, 15 cm long and 1 cm in diameter, on the side of the groove 302 effectively positions the contact base. A positioning hook 304, 8 cm long and 3 cm wide, on the side of the rod 303, and an L-shaped hook 305, 10 cm long and 5 cm wide, below, ensure the contact base is securely fixed to the mounting frame.

[0052] Then, the screw machine is started. The X-axis servo motor 701 with a power of 2kW begins to rotate, driving the X-axis screw 702 with a diameter of 10mm and a pitch of 5mm. This causes the X-axis horizontal moving screw sleeve 703, which is sleeved on the outer surface of the screw, to move horizontally along the X-axis direction, thereby driving the Y-axis housing 603 connected to the sleeve to move.

[0053] Once the Y-axis housing 603 is positioned appropriately, the 5MPa Y-axis vertical pneumatic cylinder 602 begins operating, pushing the 20cm maximum travel Y-axis telescopic rod 601 up and down. A 5mm diameter drill bit 401 is installed through the 6mm diameter drill bit mounting hole 502 in the 10cm long, 3cm wide screw drill slot 501 at the lower end of the Y-axis telescopic rod 601. The drill bit is then connected to the rotating shaft 402, driving the drill bit 401 in rotation, and the screws are tightened between the circuit breaker base and the contact seat.

[0054] After the tightening operation is completed, the finished parts are stored in a parts storage cabinet 101 below the screw machine workbench 1. The dimensions of the parts storage cabinet 101 are 50 cm long, 40 cm wide, and 30 cm high. The support rod 102 below the parts storage cabinet 101 is 30 cm long and 3 cm in diameter. The cushioning pad 103 below the support rod 102 is 10 cm long, 10 cm wide, and 2 cm thick, which can reduce vibrations generated during operation.

[0055] The working process of the screw machine for the circuit breaker base and contact seat:

[0056] Preparation: Place the circuit breaker base and contact base to be screwed onto the contact base mounting bracket 301 on the screw machine workbench 1. Ensure that the contact base is placed on the contact base positioning groove surface 302. The side positioning rod 303, positioning hook 304, and L-shaped hook bracket 305 below fix and position it to keep it stable during processing.

[0057] Adjusting the position of drill bit 401: The Y-axis vertical motion pneumatic cylinder 602 of the drill bit Y-axis vertical motion mechanism 6 drives the Y-axis vertical motion telescopic rod 601 to adjust the drill bit 401 to the desired height. Using the drill bit mounting position adjustment structure 5, the drill bit 401 is adjusted within the drill bit mounting slide slot 501 and secured through the drill bit mounting hole 502 to ensure that the drill bit 401 is accurately aligned with the screw hole.

[0058] Horizontal Movement Adjustment: Activate the X-axis servo motor 701 of the drill bit's X-axis horizontal movement mechanism 7, rotating the X-axis screw 702 and causing the X-axis horizontal movement sleeve 703, which is mounted on the outer surface of the X-axis screw 702, to move horizontally along the X-axis. The X-axis horizontal movement sleeve 703 drives the Y-axis housing 603, along with the connected drill bit's Y-axis vertical movement mechanism 6 and drill bit tightening mechanism 4, to move along the X-axis, moving the drill bit 401 to the position where the screw is to be tightened.

[0059] Screw tightening operation: The drill servo motor 403 is activated, which drives the drill connecting shaft 402 to rotate, thereby starting the rotation of the screw drill bit 401. The screw drill bit 401 moves downward under the action of the Y-axis vertical movement mechanism, screwing the screw into the screw hole of the circuit breaker base and the contact seat, completing the screw tightening operation.

[0060] Repeat the steps above to tighten the other screw holes on the circuit breaker base and contact holder until all screws are installed.

[0061] Parts Storage and Equipment Support: The parts storage cabinet 101 below the screw machine workbench 1 is used to store screws and other parts for easy access during operation. The support rods 102 and cushions 103 below the parts storage cabinet 101 support the entire equipment and reduce vibration and noise generated during operation.
