Description

Technical Field

[0001] This application relates to the field of shock absorber assembly technology, specifically to an automatic assembly and testing spring machine. Background Technology

[0002] Shock absorbers, commonly used components in automobiles, motorcycles, and other vehicles, have played a crucial role in the development of transportation. With the continuous advancement of the automotive and motorcycle industries, the performance and quality requirements for shock absorbers have also increased. Shock absorbers effectively reduce vibrations caused by uneven road surfaces during vehicle operation, improving ride comfort and enhancing vehicle handling stability and safety, thus positively contributing to the development of the entire transportation industry. In the vehicle manufacturing process, the assembly quality of shock absorbers directly affects the overall performance and quality of the vehicle.

[0003] In the existing shock absorber spring press-fit process, to ensure the spring retains its energy storage state after preload release, it is typically necessary to fit the spring onto the damper, preload the spring, and then screw the lifting ring onto the damper's spring rod. Currently, the industry generally uses manual methods for screwing the lifting ring onto the spring rod. Operators manually align the lifting ring with the spring rod and screw it into place by rotation. This method is particularly common in some small manufacturing enterprises because its equipment investment cost is relatively low. In addition, some companies use simple auxiliary tools to assist manual operation, but essentially, the screwing process still relies on manual operation.

[0004] The existing method of manually screwing on the lifting rings has obvious drawbacks. On the one hand, manual operation is labor-intensive, and long-term repetitive labor can easily lead to operator fatigue, thereby affecting production efficiency. On the other hand, due to the subjectivity and uncertainty of manual operation, the consistency of assembly is poor. There may be differences in the operation between different operators or the same operator at different times, which leads to inconsistent quality of finished products and makes it difficult to guarantee the overall performance and quality of the shock absorber. Utility Model Content

[0005] To overcome the problem of poor finished product quality caused by manual assembly in the prior art, this application provides an automatic assembly and inspection spring machine.

[0006] This application adopts the following technical solution: an automatic assembly and testing spring machine, including a cabinet and a compression mechanism and a clamping mechanism disposed on the upper inner side of the cabinet, wherein the compression mechanism is used to compress the spring and spring rod in the vertical direction, and the clamping mechanism is used to clamp the spring, characterized in that a screw-connecting mechanism is provided on the lower inner side of the cabinet, wherein the screw-connecting mechanism is used to screw-connect the lifting ring and the spring rod;

[0007] The screwing mechanism includes a motor, a hydraulic cylinder, and a tightening sleeve. The lifting ring to be screwed is placed on the tightening sleeve. The lifting ring has a threaded hole, which is coaxial with the spring rod. The motor is used to drive the tightening sleeve to rotate, and the hydraulic cylinder is used to drive the motor and the tightening sleeve to reciprocate in the vertical direction.

[0008] Optionally, the tightening sleeve is connected to the end of the output shaft of the motor, and the tightening sleeve is coaxially arranged with the output shaft of the motor;

[0009] The push rod of the hydraulic cylinder is connected to the bottom of the electric motor, and the push rod of the hydraulic cylinder is coaxially arranged with the output shaft of the electric motor.

[0010] Optionally, the compression mechanism includes an upper clamp, a lower clamp, and a first cylinder. The spring rod is engaged between the upper clamp and the lower clamp. The lower clamp is in a fixed state. The first cylinder is used to drive the upper clamp to reciprocate in the vertical direction.

[0011] Optionally, the clamping mechanism includes a clamping clamp and a second cylinder, the second cylinder being used to drive the clamping clamp to move horizontally and clamp the spring, the spring being able to contract vertically inside the clamping clamp.

[0012] Optionally, the clamping clamp is located between the upper clamp and the lower clamp.

[0013] Optionally, the cabinet is further provided with a dispensing mechanism, which includes a base, a third cylinder and a dispensing head. The top of the base faces the inclined surface of the tightening sleeve. The third cylinder is located on the inclined surface. The dispensing head is fixed on the push rod of the third cylinder. The third cylinder is used to drive the dispensing head to move closer to or away from the tightening sleeve. The dispensing head is used to inject adhesive into the threaded hole.

[0014] Optionally, a baffle is fitted on the outer side of the output shaft of the motor. The baffle is located below the table surface of the cabinet and installed below the tightening clamp. A compression spring is provided between the baffle and the end of the motor to support the baffle.

[0016] The automatic screw-on mechanism connects the lifting ring and spring rod, reducing manual operation and workload.

[0021] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] like Figure 1-3 As shown, an automatic assembly and testing machine for spring 4 includes a cabinet 1, a compression mechanism 2, a clamping mechanism 3, a screw-on mechanism 6, and a dispensing mechanism 8. The compression mechanism 2, clamping mechanism 3, and dispensing mechanism 8 are located on the upper inner side of the cabinet 1, while the screw-on mechanism 6 is located on the lower inner side of the cabinet 1. A table is provided inside the cabinet 1, with the compression mechanism 2 and clamping mechanism 3 located above the table, and the screw-on mechanism 6 located below the table. The compression mechanism 2 is used to compress the spring 4 and spring rod 5 vertically, the clamping mechanism 3 is used to clamp the spring 4, and the screw-on mechanism 6 is used to screw the lifting ring 7 and spring rod 5 together. This allows the lifting ring 7 to be automatically assembled onto the spring rod 5, reducing manual labor intensity and improving assembly consistency and finished product quality.

[0023] The screwing mechanism 6 includes a motor 61, a hydraulic cylinder 62, and a tightening sleeve 63. The motor 61 is connected to the tightening sleeve 63 via a coupling, or the tightening sleeve 63 can be directly fixed to the output shaft of the motor 61. The lifting ring 7 to be screwed is placed on the tightening sleeve 63. The lifting ring 7 has a threaded hole 70, which is coaxially arranged with the spring rod 5. The hydraulic cylinder 62 drives the motor 61 and the tightening sleeve 63 to reciprocate vertically. The push rod of the hydraulic cylinder 62 is connected to the bottom of the motor 61, and the push rod of the hydraulic cylinder 62 is coaxially arranged with the output shaft of the motor. Thus, under the simultaneous action of the motor 61 and the hydraulic cylinder 62, the tightening sleeve 63 can move in a rotating and upward posture, thereby reliably screwing the lifting ring 7 to the spring rod 5.

[0024] The compression mechanism 2 includes an upper clamp 21, a lower clamp 22, and a first cylinder 23. The upper clamp 21 and the lower clamp 22 are components used to fix the spring rod 5. The spring rod 5 is engaged between the upper clamp 21 and the lower clamp 22, with the lower clamp 22 in a fixed state. The first cylinder 23 drives the upper clamp 21 to reciprocate vertically. Furthermore, the lower clamp 22 has a channel at its lower part. When the first cylinder 23 drives the upper clamp 21 to move downward, the lower end of the spring rod 5 can move downward through the channel to below the lower clamp 22, thereby enabling the tightening sleeve 63 to reliably align the lifting ring 7 with the lower end of the spring rod 5 and complete the screw connection.

[0025] The clamping mechanism 3 includes a clamping clamp 31 and a second cylinder 32. The clamping clamp 31 is used to clamp the spring 4. The clamping clamp 31 can be composed of two semi-circular clamping blocks, and its opening and closing action is achieved by driving the second cylinder 32. The second cylinder 32 is used to drive the clamping clamp 31 to move horizontally and clamp the spring 4. The spring 4 can retract vertically inside the clamping clamp 31. The clamping clamp 31 is located between the upper clamp 21 and the lower clamp 22, which allows for better clamping of the spring 4, preventing horizontal displacement of the spring 4 during compression and not affecting the vertical extension and contraction of the spring 4.

[0026] The dispensing mechanism 8 includes a base 81, a third cylinder 82, and a dispensing head. The top of the base 81 faces the inclined surface 810 of the tightening sleeve 63. The third cylinder 82 is located on the inclined surface 810, and the dispensing head is fixed on the push rod of the third cylinder 82. The third cylinder 82 is used to drive the dispensing head to move closer to or away from the tightening sleeve 63. Due to the inclined setting of the inclined surface 810, it is ensured that the dispensing head can accurately inject the adhesive into the threaded hole 70 without colliding with other parts. Specifically, before the lifting ring 7 is screwed onto the spring pull rod 5, the third cylinder 82 is activated to move the dispensing head above the threaded hole 70 of the lifting ring 7, and then the adhesive is injected into the threaded hole 70 through the dispensing head. In this way, after the adhesive solidifies, a strong seal and fastening effect can be formed between the lifting ring 7 and the spring pull rod 5 to prevent the lifting ring 7 from loosening during use.

[0027] A baffle 64 is fitted onto the outer side of the output shaft of the motor 61. The baffle 64 is located below the table surface of the cabinet 1 and below the tightening sleeve 63. A compression spring 65 is provided between the baffle 64 and the end of the motor 61. When the tightening sleeve 63 is screwed onto the lifting ring 7, the baffle 64 can block the waste generated during the tightening process, preventing these debris from entering other components inside the cabinet 1 and affecting the normal operation of the equipment. At the same time, the baffle 64 can block the glue dripping during the dispensing process, preventing the glue from damaging the hydraulic cylinder 62 or the motor 61. The cooperation between the baffle 64 and the compression spring 65 ensures that when the hydraulic cylinder 62 drives the motor 61 and the tightening sleeve 63 to move upward, the baffle 64 can remain stationary under the blocking effect of the table surface, thus reliably providing a shielding function. Furthermore, an infrared sensor is also installed on the table. The infrared sensor is located outside the compression mechanism 2, clamping mechanism 3, screwing mechanism 6 and dispensing mechanism 8. When the spring 4 and spring rod 5 are clamped manually, the infrared sensor will receive a signal. At this time, the motor 61, hydraulic cylinder 62, first cylinder 23, second cylinder 32 and third cylinder 82 will not operate, ensuring operational safety.

[0028] The implementation principle of this embodiment is as follows: When using the automatic assembly and testing spring 4 machine, the spring 4 is first sleeved on the spring rod 5, and then placed between the upper clamp 21 and the lower clamp 22. The first cylinder 23 is activated, driving the upper clamp 21 to move downward, compressing the spring 4 and the spring rod 5. Next, the second cylinder 32 is activated, driving the clamping clamp 31 to clamp the spring 4. The lifting ring 7 to be screwed is placed on the tightening sleeve 63, and the hydraulic cylinder 62 is activated, moving the tightening sleeve 63 and the lifting ring 7 upward to a position aligned with the spring rod 5. The motor 61 is activated, driving the tightening sleeve 63 to rotate, thereby screwing the lifting ring 7 onto the spring rod 5. The entire process is automated, avoiding the problems of high labor intensity and poor assembly consistency associated with manually screwing the lifting ring 7, thus improving production efficiency and finished product quality.

[0029] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
