Description

Technical Field

[0001] This invention relates to the field of gas spring technology, specifically to an integrated intelligent testing and assembly machine for gas springs. Background Technology

[0002] A gas spring is an industrial component that provides support, cushioning, braking, height adjustment, and angle adjustment. It consists of the following parts: a pressure cylinder, piston rod, piston, sealing guide sleeve, filling material (inert gas or an oil-gas mixture), internal and external control elements (referring to the controllable gas spring), and connectors.

[0003] In the existing technology, gas springs need to be compressed for life testing and assembled with straps before leaving the factory. However, the existing compression methods for gas springs are mostly manual compression by workers using simple brackets for life testing and strap assembly. This is inefficient, too labor-intensive for workers, and the testing process is inaccurate, which can no longer meet the usage requirements. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: an integrated intelligent inspection and assembly machine for gas springs, comprising:

[0005] A gas spring compression mechanism, comprising a controller, a drive mechanism for compressing the gas spring according to the controller's instructions, a retractable mechanism for fixing the gas spring, and a pressure sensor.

[0006] The drive end of the drive mechanism is connected to one end of the retractable mechanism, and the other end of the retractable mechanism contacts the pressure sensor.

[0007] The controller controls the drive mechanism to compress one end of the telescopic mechanism, thereby compressing the gas spring and causing the other end of the telescopic mechanism to press against the pressure sensor. The pressure sensor then transmits the pressure data to the display screen for display.

[0008] As a preferred embodiment of the present invention, it further includes a fixing base for fixing the gas spring compression mechanism.

[0009] As a preferred embodiment of the present invention, it further includes an angle adjustment mechanism connected between the fixed base and the gas spring compression mechanism, for adjusting the angle between the gas spring compression mechanism and the ground, wherein the angle range is 0-90 degrees.

[0010] As a preferred embodiment of the present invention, the gas spring compression mechanism includes a test frame and at least one slide rod fixed inside the test frame, and the telescopic mechanism includes a first slide block and a second slide block;

[0011] The fixed end of the drive mechanism is fixed to one end of the test frame, and the pressure sensor is fixed to the other end of the test frame. Slider 1 and Slider 2 are respectively strung on the slide rod. The drive end of the drive mechanism is in contact with one end of Slider 1. The two ends of the gas spring are respectively fixed between the other end of Slider 1 and one end of Slider 2. The other end of Slider 2 is in contact with the pressure sensor.

[0012] As a preferred embodiment of the present invention, a slider three is also provided inside the test frame and is connected in the slide bar, and the pressure sensor is fixed on the slider three.

[0013] As a preferred embodiment of the present invention, at least one limit switch connected to the controller is provided on one side of the test frame. The limit switch stops when the slider slides to the position corresponding to the limit switch. Alternatively, the controller can control the drive mechanism to drive in the opposite direction.

[0014] As a preferred embodiment of the present invention, a counter connected to the controller is provided on one side of the test fixture, and the counter is located next to the limit switch.

[0015] As a preferred embodiment of the present invention, a clutch device is also provided on the slider three, and a pressure sensor is located between the clutch device and the slider two. The clutch device is used to control the contact between the slider two and the pressure sensor.

[0017] As a preferred embodiment of the present invention, positioning pins are provided on slider one and slider two respectively, and the two ends of the gas spring are respectively movably sleeved on the positioning pins. A groove for easy threading of a strap is also provided at the positioning pin of slider one.

[0018] As a preferred technical solution of the present invention, an adjusting screw is provided at one end of the test frame. One end of the adjusting screw is screwed into one end of the test frame by a thread, and the other end is fixedly connected to the slider.

[0019] Compared with the prior art, the present invention provides an integrated intelligent detection and assembly machine for gas springs, which has the following beneficial effects:

[0020] This automated equipment for gas spring life testing and compression assembly, by setting up a gas spring compression mechanism and a fixed base, can automatically compress the gas spring compared to manually compressing the gas spring using a simple support. This saves time and effort, and the assembly and strapping process is faster. At the same time, pressure testing can be performed using a pressure gauge, and the life of the gas spring can also be tested by the reciprocating motion of the drive mechanism. The angle adjustment mechanism can adjust the angle of the gas spring compression mechanism, ensuring the usability of the device and meeting the testing requirements of 0-360 degrees.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-7The intelligent testing and assembly machine for gas springs includes a gas spring compression mechanism 1. The gas spring compression mechanism 1 includes a controller, a drive mechanism 11 for compressing the gas spring according to the controller's instructions, a retractable mechanism 12 for fixing the gas spring, and a pressure sensor 13. The drive end of the drive mechanism 11 is connected to one end of the retractable mechanism 12, and the other end of the retractable mechanism 12 contacts the pressure sensor 13. The drive mechanism 11 can be a cylinder, electric cylinder, hydraulic cylinder, or other power equipment with equivalent effect. Activating the drive mechanism 11 will push the slider 121 to cooperate with the slider 22 to compress the gas spring.

[0031] The controller controls the drive mechanism 11 to compress one end of the telescopic mechanism 12, thereby compressing the gas spring and causing the other end of the telescopic mechanism 12 to press against the pressure sensor 13. The pressure sensor 13 transmits the pressure data to the display screen 4 through the controller for display.

[0032] As a specific technical solution in this embodiment, it also includes a fixing base 2 for fixing the gas spring compression mechanism 1. The fixing base 2 supports the gas spring compression mechanism 1, and a display screen 4, a start switch 5, and a foot pedal control switch 6 are also installed on one side of the fixing base 2, all of which are controlled and coordinated by the controller. The start switch 5 is generally set as an automatic switch, and the foot pedal control switch 6 is controlled as needed. For example, the foot pedal control switch 6 can be used when assembling the gas spring with straps.

[0033] As a specific technical solution in this embodiment, it also includes an angle adjustment mechanism 3 connected between the fixed base 2 and the gas spring compression mechanism 1, used to adjust the angle between the gas spring compression mechanism 1 and the ground, the angle range being 0-90 degrees. (See reference...) Figure 1 The angle adjustment mechanism 3 includes an oil pump installed inside the fixed base 2 and an oil cylinder installed on the oil pump. The oil cylinder is lifted and the air spring compression mechanism 1 rotates the cylinder from 0 to 90 degrees to adapt to the usage habits of different workers and the operational needs of different tests from 0 to 360 degrees.

[0034] As a specific technical solution of this embodiment, the gas spring compression mechanism 1 includes a test frame 14 and at least one slide rod 15 fixed inside the test frame 14. The telescopic mechanism 12 includes a first slide rod 121 and a second slide rod 122. The fixed end of the drive mechanism 11 is fixed to one end of the test frame 14, and the other end of the test frame 14 is fixed to a pressure sensor 13. The first slide rod 121 and the second slide rod 122 are respectively connected to the slide rod 15. The drive end of the drive mechanism 11 is in contact with one end of the first slide rod 121. The two ends of the gas spring are respectively fixed between the other end of the first slide rod 121 and one end of the second slide rod 122. The other end of the second slide rod 122 is in contact with the pressure sensor 13. The arrangement of the slide rod 15 ensures the stability of the drive mechanism 11, the first slide rod 121 and the second slide rod 122. The test frame 14 is hinged to the fixed base 2 to realize the angle adjustment mechanism 3 to adjust the angle of the gas spring compression mechanism 1.

[0035] As a specific technical solution in this embodiment, a slider 16 is also provided in the test frame 14 and is connected in the slide bar 15. The pressure sensor 13 is fixed on the slider 16. The slider 16 is used to install the pressure sensor 13 and the clutch device 18. When the pressure sensor 13 is not used, for example when only the gas spring is installed, the slider 122 will not contact the pressure sensor 13 by moving the clutch device 18.

[0036] As a specific technical solution in this embodiment, at least one limit switch 17 connected to the controller is also provided on one side of the test frame 14. When the slider 121 slides to the position corresponding to the limit switch 17, it stops. Alternatively, the controller can control the drive mechanism 11 to drive in the opposite direction. The limit switch 17 is used to display the movement range of the slider 121. When the slider 121 is triggered by the limit switch 17, the drive mechanism 11 is started to drive the slider 121 to move in the opposite direction to the current movement direction. Two limit switches 17 can be set, located at the starting position and the ending position of the slider 121 respectively, to control the slider 121 to slide between the starting position and the ending position. At this time, the gas spring is compressed back and forth, which can be used to test the life of the gas spring.

[0037] To facilitate setting the position of the limit switch 17, a slide bar 15 can be provided on one side of the test frame 14, and the limit switches 17 are connected in series on the slide bar 15. When it is necessary to adjust the position of the limit switch 17, the limit switch 17 can be moved directly on the slide bar 15.

[0038] As a specific technical solution in this embodiment, a clutch device 18 is also provided on the slider 3 16. The pressure sensor 13 is located between the clutch device 18 and the slider 2 122. The clutch device 18 is used to control the contact between the slider 2 122 and the pressure sensor 13. The clutch device 18 includes a clutch lever and a clutch plate. When the pressure sensor 13 is not needed, such as when only the life test of the gas spring is performed, the pressure sensor 13 is not needed. At this time, the clutch device 18 can be used to switch to protect the life of the pressure sensor 13.

[0039] As a specific technical solution in this embodiment, a return spring 19 is also provided at one end of the slider 121 and the test frame 14 to pull the slider 121 back to the starting position. The return spring 19 is provided so that when the drive mechanism 11 disengages from pushing the slider 121, the return spring 19 can quickly pull the slider 121 back to the starting position.

[0040] As a specific technical solution in this embodiment, positioning pins 123 are respectively provided on slider one 121 and slider two 122. The two ends of the gas spring are respectively movably sleeved on the positioning pins 123. A groove 124 for easy threading of a strap is also provided at the positioning pin 123 of slider one 121. (See reference) Figure 1 The groove 124 makes it easier for staff to install the straps. The two ends of the gas spring are fitted onto the positioning pins 123, making the assembly process simple and quick.

[0041] As a specific technical solution in this embodiment, an adjusting screw is provided at one end of the test frame 14. One end of the adjusting screw is screwed onto one end of the test frame 14 by a thread, and the other end is fixedly connected to the slider 16. The position of the slider 16 and the pressure sensor 13 can be adjusted by adjusting the screw, so that the slider 122 has room to move back to adapt to gas springs of different specifications.

[0042] When using, refer to the figure. Place the two ends of the gas spring to be compressed onto the two positioning pins 123 respectively. Start the drive mechanism 11 to push the slider 121 to cooperate with the slider 2 122 to compress the gas spring. Then the strap can be installed. When it is necessary to measure the pressure of the gas spring, move the clutch device 18 so that the slider 2 122 contacts the pressure sensor 13 for measurement. When testing the life of the gas spring, there is no need to install the strap. Start the drive mechanism 11 to run back and forth. If only the strap needs to be installed, move the clutch device 18 so that the slider 2 122 does not contact the pressure sensor 13. At this time, the pressure sensor 13 is not needed. When it is necessary to change the test angle, start the angle adjustment mechanism 3 to lift the test frame 14 for adjustment from 0 to 90 degrees.

[0043] Additionally, a counter connected to the controller is provided on one side of the test rack 14. The counter is located next to the limit switch 17 or at the position of the pressure sensor 13. It is used to count the number of times the gas spring is tested back and forth. The controller can output the counter value to the display screen 4 for easy viewing of the gas spring's back and forth test count value.

[0044] In summary, this automated equipment for gas spring life testing and compression assembly, by setting up a gas spring compression mechanism 1 and a fixed base 2, can automatically compress the gas spring compared to manually compressing the gas spring using a simple support. This saves time and effort, and the assembly and strapping process is faster. At the same time, pressure testing can be performed using a pressure gauge, and the life of the gas spring can also be tested by the reciprocating motion of the drive mechanism 11. The angle adjustment mechanism 3 can adjust the angle of the gas spring compression mechanism 1, ensuring the usability of the device and the testing requirements of 0-360 degrees.
