Description

Technical Field

[0001] The present disclosure relates to the technical field of shock absorber assembly, and particularly relates to a double-station screwing device for shock absorbers. Background Art

[0002] With the development of the economy and the progress of society, reducing labor intensity and improving product quality have become an inevitable trend in the manufacturing industry; the emergence of various automated devices, with features such as convenient use, space saving, safety and efficiency, quality assurance, and multi-functional capabilities, has made the post-rear shock absorber automated device an essential part of shock absorber assembly. Usually, shock absorber assembly is divided into manual assembly and single-station assembly, which have the disadvantages of single variety, low efficiency, unstable quality, and high labor intensity.

[0003] After retrieval, it can be known that in the prior art, for example, patent CN202320066033.0 discloses a shock absorber assembly device, which is characterized in that: it includes a frame, a support seat, a push rod arranged on the support seat, a clamping device arranged outside the push rod, an oil seal top pressing ring concentric with the push rod, and a fixed part screwing device that can be lifted above the push rod; the oil seal top pressing ring can move axially along the push rod; and to improve work efficiency, two sets of assembly mechanisms can be set on one assembly device to alternately assemble shock absorbers, thereby improving the assembly efficiency. The above shock absorber assembly device still has the following defects in practical applications:

[0004] First, the two sets of assembly mechanisms can only be used alternately, that is, the two sets of assembly mechanisms do not work simultaneously, but alternately assemble shock absorbers at a certain time interval or according to the number of assemblies. This means that when one set of assembly mechanism is performing assembly, the other set of mechanism may be in a standby, maintenance, adjustment, or preparation state for the next assembly cycle. This makes the device unable to assemble two shock absorbers simultaneously, and during the alternating operation of the two sets of assembly mechanisms, there may be some uncertain factors, such as insufficient supply of parts and worker operation errors, which may affect the smooth progress of the alternation.

[0005] Second, this shock absorber assembly device can only perform the assembly of single-tube shock absorbers and cannot be used for the assembly of double-tube shock absorbers, which limits the scope of application and is not suitable for the assembly of multiple product varieties. Summary of the Utility Model

[0006] To solve the problems existing in the above-mentioned prior art, the present disclosure aims to provide a shock absorber double-station screwing device. The shock absorber double-station screwing device having at least two sets of screwing components means that two shock absorber components can be screwed and assembled simultaneously. Compared with single-station devices, the production efficiency is significantly improved, and the cost can be reduced; and this device can handle both the screwing and assembly of single-tube shock absorber components and the screwing and assembly of double-tube shock absorber components. This flexibility enables the device to adapt to the production requirements of shock absorbers of different models and specifications, reducing the time and cost of production line adjustment.

[0031] AsFigure 1 - Figure 2 As shown in and

[0032] , a double-station screwing device for a shock absorber according to the present disclosure includes a frame body 10 and at least two sets of screwing assemblies 20 provided on the frame body 10.

[0032] Each set of screwing assemblies 20 includes a tensioning and rotating mechanism 201, a pressing mechanism 202, a stop block 203, a first driving mechanism, and a second driving mechanism 204. The tensioning and rotating mechanism 201 is rotatably connected to the frame body 10. The pressing mechanism 202 is disposed above the tensioning and rotating mechanism 201 and connected to the frame body 10. The stop block 203 is disposed on one side of the tensioning and rotating mechanism 201 and spaced apart from the tensioning and rotating mechanism 201 by a certain distance. Each set of screwing assemblies 20 has a corresponding driving mechanism, so that when two sets of screwing assemblies 20 are used, the two sets can work simultaneously, that is, perform double-station screwing processing. The tensioning and rotating mechanism 201 can be replaced with a tensioning and rotating mechanism 201 of a corresponding size according to the size of the component to be processed, and the tensioning and rotating mechanisms 201 of the two sets of screwing assemblies 20 can adopt different sizes, that is, the screwing and assembly of shock absorber components of different sizes can be carried out simultaneously.

[0033] The first driving mechanism is rotatably connected to the tensioning and rotating mechanism 201. By driving the first driving mechanism, the tensioning and rotating mechanism 201 rotates in the horizontal direction. The second driving mechanism 204 is connected to the pressing mechanism 202. By driving the second driving mechanism 204, the pressing mechanism 202 moves in the vertical direction. The first driving mechanism is disposed inside the frame body 10. The first driving mechanism can select a rotating motor, and the second driving mechanism can select a pneumatic cylinder.

[0034] The screwing and assembly of the single-tube shock absorber component 40 is realized by the cooperation of the tensioning and rotating mechanism 201 and the pressing mechanism 202. By placing the single-tube shock absorber component 40 on the tensioning and rotating mechanism 201, the pressing mechanism 202 moves in the vertical direction closer to the tensioning and rotating mechanism 201 until it contacts and fixes the top of the single-tube shock absorber component 40. The tensioning and rotating mechanism 201 rotates, driving the part of the single-tube shock absorber component 40 that is not fixed by the pressing mechanism 202 to rotate, thereby completing the screwing and assembly of the single-tube shock absorber component 40.

[0035] The screwing and assembly of the double-tube shock absorber component 50 is realized by the cooperation of the tensioning and rotating mechanism 201 and the stop block 203. By placing the double-tube shock absorber component 50 on the tensioning and rotating mechanism 201, the tensioning and rotating mechanism 201 rotates, driving the double-tube shock absorber component 50 to rotate. One of the tubes of the double-tube shock absorber component 50 abuts against the outer surface of the stop block 203, so that the tube abutting against the outer surface of the stop block 203 cannot rotate, and the other tube rotates, thereby realizing the screwing and assembly of the double-tube shock absorber component 50.

[0036] The above-mentioned presence of at least two sets of screwing components 20 means that screwing assembly can be carried out on two shock absorber components simultaneously. Compared with single-station equipment, the production efficiency is significantly improved, and the cost can be reduced. Moreover, this equipment can not only realize the screwing assembly of the single-tube shock absorber component 40 through the cooperation of the tensioning rotation mechanism and the pressing mechanism, but also realize the screwing assembly of the double-tube shock absorber component 50 through the cooperation of the tensioning rotation mechanism and the stopper. This flexibility enables the equipment to adapt to the production requirements of shock absorbers of different models and specifications, reducing the time and cost of production line adjustment.

[0037] Further, in this embodiment, the pressing mechanism 202 includes an upper pressing plate 2021, a lower pressing plate 2022, and two sliding rods 2023. The two sliding rods 2023 are respectively arranged on both sides of the tensioning rotation mechanism 201. The upper pressing plate 2021 and the lower pressing plate 2022 are slidably connected to the sliding rods 2023 in the vertical direction from top to bottom in sequence, and the upper pressing plate 2021 and the lower pressing plate 2022 slide in the vertical direction along the sliding rods 2023; the upper pressing plate 2021 and the lower pressing plate 2022 can adjust their corresponding initial positions by sliding along the sliding rods 2023.

[0038] Further, in this embodiment, the double-station screwing equipment for shock absorbers further includes a connecting member 30. Both the upper pressing plate 2021 and the lower pressing plate 2022 have through holes adapted to the connecting member 30. One end of the connecting member 30 is connected to the frame body 10, and the other end passes through the upper pressing plate 2021 and the lower pressing plate 2022, and the connecting member 30 is connected to the upper pressing plate 2021;

[0039] The connecting member 30 can be selected as a bolt. One end of the bolt is connected to the frame body 10, and the other end passes through the upper pressing plate 2021, and then is tightened by a nut to fix the upper pressing plate 2021. And the length of the bolt is half of the length of the sliding rod 2023, so that the upper pressing plate 2021 can be adjusted to a suitable initial position and then tightened by a nut.

[0040] Further, in this embodiment, the second driving mechanism 204 is fixedly arranged on the upper pressing plate 2021. The upper pressing plate 2021 has a through hole adapted to the output end of the second driving mechanism 204. The output end of the second driving mechanism 204 passes through the upper pressing plate 2021 and is connected to the lower pressing plate 2022 to drive the lower pressing plate 2022 to move closer to or away from the upper pressing plate 2021 in the vertical direction;

[0041] When the lower pressing plate 2022 moves closer to the upper pressing plate 2021 in the vertical direction, it means moving away from the tensioning rotation mechanism 201;

[0042] When the lower pressing plate 2022 moves away from the upper pressing plate 2021 in the vertical direction, it means moving closer to the tensioning rotation mechanism 201.

[0043] Further, in this embodiment, a fixed end 205 is provided on the side of the lower pressing plate 2022 away from the upper pressing plate 2021. The fixed end 205 is adapted to the end of the single-tube shock absorber component 40 and is used to fix the end of the single-tube shock absorber component 40 during the screwing process.

[0044] The fixed end 205 has a groove adapted to the end of the single-tube shock absorber component 40. When the fixed end 205 contacts the end of the single-tube shock absorber component 40, the end of the single-tube shock absorber component 40 is clamped by the groove, and thus the end of the single-tube shock absorber component 40 can be fixed during the screwing process.

[0045] Further, in this embodiment, the screwing assembly 20 further includes a tension switch button 206. The tension switch button 206 is arranged on the frame 10 and is used to control the start and stop of the tension rotation mechanism 201. By controlling the start and stop of the tension rotation mechanism 201 through the tension switch button 206, the number of groups of the screwing assembly 20 that can be used can be selected according to specific situations, avoiding the idle operation of the unused screwing assembly 20.

[0046] Further, in this embodiment, the frame 10 is provided with a control panel 101 and a control switch assembly 102. A circuit assembly is arranged inside the frame 10. Both the control panel 101 and the control switch assembly 102 are electrically connected to the circuit assembly. The control panel 101 is used to set the working parameters of the equipment, and the control switch assembly 102 is used for operations such as starting, shutting down, and emergency stopping of the whole equipment.

[0047] Further, in this embodiment, an alarm lamp 103 is provided on the top of the frame 10. Each group of screwing assemblies 20 corresponds to an alarm lamp 103. When a corresponding screwing assembly 20 fails, the alarm lamp 103 will light up and give an alarm. At this time, it is convenient for the staff to quickly find out which group of screwing assemblies 20 has problems and carry out repairs.

[0048] Further, in this embodiment, the frame 10 is further provided with a plurality of heat dissipation holes 104. The heat dissipation holes 104 are located on both sides and above the frame 10. The heat dissipation holes 104 are used to dissipate heat from the frame 10 during operation.

[0049] Further, in this embodiment, a storage cabinet 105 is further provided below the frame 10. The storage cabinet 105 can be used to place maintenance parts or processing parts, which is convenient for maintenance and processing.

[0050] The working process of a double-station screwing device for shock absorbers in this embodiment will be fully described below in combination with the above content.

[0051] For the screwing assembly of the single-tube shock absorber component 40, the tensioning and rotating mechanisms 201 of the two groups of screwing assemblies 20 are both placed with the single-tube shock absorber component 40. Then, driven by the second driving mechanism 204, the lower pressing plate 2022 moves away from the upper pressing plate 2021 in the vertical direction, that is, moves closer to the tensioning and rotating mechanism 201 until the fixed end 205 contacts and fixes the top of the single-tube shock absorber component 40. The tensioning and rotating mechanisms 201 of the two groups of screwing assemblies 20 rotate, driving the part of the single-tube shock absorber component 40 that is not fixed by the fixed end 205 to rotate, thereby completing the screwing assembly of the single-tube shock absorber component 40. After the screwing assembly is completed, the second driving mechanism 204 drives the lower pressing plate 2022 to move closer to the upper pressing plate 2021 in the vertical direction, so that the fixed end 205 loosens and disengages from the top of the single-tube shock absorber component 40, realizing the screwing assembly of the single-tube shock absorber component 40 with double workstations.

[0052] For the screwing assembly of the double-tube shock absorber component 50, the tensioning and rotating mechanisms 201 of the two groups of screwing assemblies 20 are both placed with the double-tube shock absorber component 50. The tensioning and rotating mechanisms 201 of the two groups of screwing assemblies 20 rotate, driving the double-tube shock absorber component 50 to rotate. One of the tubes of the double-tube shock absorber component 50 abuts against the outer surface of the stop block 203, so that the tube abutting against the outer surface of the stop block 203 cannot rotate, and the other tube rotates, thereby completing the screwing assembly of the double-tube shock absorber component 50, realizing the screwing assembly of the double-tube shock absorber component 50 with double workstations.
