Description

Technical Field

[0001] The utility model relates to the field of screw locking, in particular to a screw locking station of circuit breaker housing assembly equipment. Background Art

[0002] In the field of electrical equipment manufacturing, circuit breakers are important protective devices. The assembly quality of the circuit breaker housing directly affects the performance and reliability of the circuit breaker. During the assembly process of the circuit breaker housing, each component must be precisely assembled and tightened with screws to ensure the structural strength and sealing of the housing.

[0003] The screw locking machine proposed in the Chinese utility model patent application No. CN202123171773.0 includes an electric screwdriver and a mounting part. The electric screwdriver includes a main unit fixed on the mounting part and a screwdriver bit driven to rotate by the main unit. The screwdriver bit can be rotatably inserted into the center hole of the holder. The holder can be reciprocated along the axial direction of the screwdriver bit on the mounting part. The holder can be moved to the end of the screwdriver bit and extend to the outside of the holder. An elastic part is provided between the holder and the main unit.

[0004] However, there are some shortcomings in the existing screw locking process that still need to be improved. In the existing technology, there may be a lack of efficient lifting and lowering adjustment and the coordinated work of the screw locking power mechanism, resulting in a slow screw locking operation speed, affecting the overall assembly efficiency. In the absence of lifting and lowering adjustment and stable power transmission, the tightness of the screws may be inconsistent, which may easily lead to assembly quality problems and affect the performance and reliability of the circuit breaker housing. The existing screw locking process has poor buffering and shock absorption effects. During the power transmission process, there is a lack of effective buffering and shock absorption measures. The impact force may cause greater vibration and wear to the equipment, shortening the service life of the equipment. Existing equipment may be difficult to flexibly adjust according to different circuit breaker housing specifications and screw locking positions, which limits its application under various assembly requirements. Therefore, we have made improvements to this and proposed a screw locking station for circuit breaker housing assembly equipment. Utility Model Content

Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0032] Example 1: Please refer to Figures 1-8 A screw locking station for circuit breaker housing assembly equipment includes a screw locking workbench 1, a circuit breaker housing 2 is provided on the screw locking workbench 1, a support frame 3 is provided on the circuit breaker housing 2, an arc-shaped base 301 is provided on the support frame 3, a lifting and adjusting power mechanism 4 is provided on the support frame 3, the lifting and adjusting power mechanism 4 is connected to the lifting and adjusting frame structure 5, a screw locking power mechanism 9 is provided on the lifting and adjusting frame structure 5, the screw locking power mechanism 9 is connected to the screw locking rotating rod 16, and a screw locking head 17 is provided at the end of the screw locking rotating rod 16.

[0033] The lift adjustment mechanism 4 is equipped with a lift adjustment cylinder 401, which is equipped with a lift adjustment telescopic rod 402. The lift adjustment frame structure 5 is equipped with a first lift adjustment plate 501 and a second lift adjustment plate 502, with an adjustment plate connecting rod 503 located between the first and second lift adjustment plates 501 and 502. Sliding sleeves 6 are installed on the first and second lift adjustment plates 501 and 502. An upper limit block 7 is installed above the sliding sleeve 6, and a lower limit block 8 is installed below the sliding sleeve 6. The screw locking mechanism 9 is equipped with a first motor 901 and a second motor 902.

[0034] The first motor 901 and the second motor 902 are each equipped with a rotating shaft 10, which is connected by a hinge 11. The end of the hinge 11 is connected to a power transmission shaft 12, which is sleeved with a spring 13. A buffer groove 14 is defined on the outside of the power transmission shaft 12, and a shift lever 15 is located within the buffer groove 14. The lift adjustment telescopic rod 402 is connected to the first lift adjustment plate 501. The first motor 901 and the second motor 902 are located above the first lift adjustment plate 501.

[0035] The working principle of the screw locking station of the circuit breaker housing 2 assembly equipment is as follows:

[0036] First, place the circuit breaker housing 2 on the screw locking workbench 1. The arc-shaped base 301 on the support frame 3 plays a supporting and fixing role.

[0037] The lift adjustment mechanism 4 is activated, and the lift adjustment cylinder 401 is activated, pushing the lift adjustment telescopic rod 402 to extend and retract. The lift adjustment telescopic rod 402 is connected to the first lift adjustment plate 501, thereby driving the first lift adjustment plate 501 to move upward and downward. The first and second lift adjustment plates 501 and 502 are connected as a whole via the adjustment plate connecting rod 503. They slide up and down on the support frame 3 via the sliding sleeve 6 to ensure stable lifting. The upper limit block 7 above the sliding sleeve 6 and the lower limit block 8 below the sliding sleeve 6 are used to limit the sliding range of the sliding sleeve 6 to prevent excessive lifting.

[0038] When the lifting and adjusting frame structure 5 is adjusted to the appropriate height, the screw locking mechanism 9 begins to operate. The first motor 901 and the second motor 902 are activated, driving the hinge 11 to rotate via the rotating shaft 10. The end of the hinge 11 is connected to the power transmission shaft 12, thereby transmitting power to the power transmission shaft 12. The power transmission shaft 12 drives the screw locking rotating rod 16 to rotate. The screw locking head 17 at the end of the screw locking rotating rod 16 tightens the screws on the circuit breaker housing 2.

[0039] During the power transmission process, the spring 13 on the power transmission shaft 12 and the buffer groove 14 and the gear lever 15 opened on the outside play a role of buffering and shock absorption, reducing the impact force caused by the rotation of the motor and ensuring the stability and accuracy of the screw locking operation.

[0040] Example 2: A screw locking station for circuit breaker housing assembly equipment, which places the circuit breaker housing 2 on the screw locking workbench 1 to stabilize and fix it. Start the lifting and adjusting power mechanism 4, and the lifting and adjusting cylinder 401 pushes the lifting and adjusting telescopic rod 402 to extend under a working pressure of 0.6MPa. The lifting and adjusting telescopic rod 402 drives the first lifting and adjusting plate 501 to rise, and the second lifting and adjusting plate 502 is synchronously raised through the adjusting plate connecting rod 503. The sliding sleeves 6 on the first lifting and adjusting plate 501 and the second lifting and adjusting plate 502 slide smoothly along the support frame 3, and the upper limit block 7 and the lower limit block 8 effectively limit the stroke of the sliding sleeve 6, ensuring that the lifting and adjusting frame structure 5 is lifted and lowered within a safe range. When the lifting and adjusting frame structure 5 rises to a suitable height to meet the requirements of the screw locking operation, the lifting and adjusting cylinder 401 stops working.

[0041] The screw locking power mechanism 9 starts to run. The first motor 901 and the second motor 902 rotate at a speed of 1500r / min, and transmit power to the power transmission shaft 12 through the rotating shaft 10 and the hinge 11. The power transmission shaft 12 drives the screw locking rotating rod 16 to rotate, and the screw locking head 17 at the end of the screw locking rotating rod 16 performs the screw locking operation on the circuit breaker housing 2. During the power transmission process, the spring 13 on the power transmission shaft 12 plays a buffering role, reducing the impact force caused by the rotation of the motor. The cooperation of the buffer groove 14 and the gear lever 15 further enhances the buffering effect and ensures the stability and accuracy of the screw locking operation.

[0042] A lifting and adjusting cylinder 401 for the screw locking station of a circuit breaker housing assembly machine has a working pressure of 0.6 MPa, a stroke of 100 mm, and a cylinder diameter of 50 mm. The lifting and adjusting telescopic rod 402 has a diameter of 20 mm and is made of stainless steel. The first and second lifting and adjusting plates 501 and 502 are 300 mm long, 200 mm wide, and 10 mm thick, and are made of aluminum alloy. The adjusting plate connecting rod 503 has a diameter of 15 mm and a length of 250 mm, and is made of stainless steel. The sliding sleeve 6 has an inner diameter of 25 mm, an outer diameter of 35 mm, and a length of 50 mm, and is made of copper. The upper and lower limit blocks 7 and 8 have a diameter of 40 mm and a thickness of 10 mm, and are made of rubber. The first and second motors 901 and 902 have a power of 500 W and a rotation speed of 1500 r / min. The rotating shaft 10 has a diameter of 10 mm and a length of 100 mm, and is made of No. 45 steel. Hinge 11: 50mm long, 30mm wide, 10mm thick, made of cast iron. Power transmission shaft 12: 12mm diameter, 150mm long, made of 45-gauge steel. Spring 13: 2mm wire diameter, 15mm outer diameter, 50mm free length, made of spring 13 steel. Buffer groove 14: 5mm wide, 3mm deep, 100mm long. Gear lever 15: 3mm diameter, 10mm long, made of stainless steel.

[0043] During the working process of a screw locking station of a circuit breaker housing assembly device, the circuit breaker housing 2 is first placed on a screw locking workbench 1 and its position is ensured to be accurate. The lifting and adjusting power mechanism 4 is started, and the lifting and adjusting cylinder 401 starts to work, pushing the lifting and adjusting telescopic rod 402 to extend.

[0044] The telescopic lift rod 402 is connected to the first lift plate 501, driving it upward. The first lift plate 501 is connected to the second lift plate 502 via the plate connecting rod 503, causing the second lift plate 502 to rise accordingly. The sliding sleeves 6 on the first and second lift plates 501, 502, slide upward on the support frame 3. The upper limit block 7 and lower limit block 8 above and below the sliding sleeves 6 limit their range of movement, ensuring a safe and stable lifting process.

[0045] When the lifting and adjusting frame structure 5 rises to the appropriate height, the lifting and adjusting cylinder 401 is stopped. The screw locking power mechanism 9 is started, and the first motor 901 and the second motor 902 begin to operate. The rotating shaft 10 on the first motor 901 and the second motor 902 drives the power transmission shaft 12 to rotate through the hinge 11. The power transmission shaft 12 drives the screw locking rotating rod 16 to rotate, and the screw locking head 17 at the end of the screw locking rotating rod 16 begins to perform the screw locking operation on the circuit breaker housing 2. During the power transmission process, the spring 13 on the power transmission shaft 12, the buffer groove 14 on the outside, and the gear lever 15 in the groove play a role of buffering and shock absorption, reducing the impact force caused by the rotation of the motor and ensuring the smooth progress of the screw locking operation. After completing one screw locking operation, adjust the height of the lifting and adjusting frame structure 5 as needed, and perform screw locking operations on other positions until all screw locking work on the circuit breaker housing 2 is completed.

[0046] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention are included in the scope of the claims of the present invention.
