Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, specifically to an adjustable oil injection device for shock absorber production. Background Technology

[0002] In the production process of shock absorbers, oil injection is a critical step, and the quality of oil injection directly affects the performance and service life of the shock absorbers.

[0003] Currently, existing vacuum oil injection machines for shock absorbers have significant drawbacks: due to the lack of an effective positioning and adjustment structure, they cannot accurately position different models of shock absorbers. Different series of shock absorbers exhibit significant differences in key parameters such as cylinder diameter and piston rod length, and the existing equipment's fixing and clamping mechanisms cannot flexibly adjust according to these parameters. When switching production models, operators often need to spend a significant amount of time on manual calibration, which not only increases labor intensity but also makes it difficult to guarantee positioning accuracy. This can lead to minor issues such as oil injection misalignment and oil overflow, resulting in material waste and environmental pollution; or more serious issues such as insufficient oil injection or seal failure, causing abnormal damping force and oil leakage in subsequent testing, significantly increasing the product defect rate.

[0004] Therefore, it is necessary to design and modify the adjustable oil injection device used in shock absorber production to effectively prevent poor positioning performance. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4As shown, an adjustable oil injection device for shock absorber production includes a base 1. A vacuum oil injection machine body 2 is fixedly connected to the right side of the top of the base 1. A lifting mechanism 3 is fixedly connected to the left side of the top of the base 1. A first drive box 4 is fixedly connected to the surface of the lifting mechanism 3. Slider blocks 5 are slidably connected to both sides inside the first drive box 4. A threaded rod 6 with positive and negative threads is rotatably connected inside the first drive box 4. The threaded rod 6 is threadedly connected to the slider 5. A first motor 7 is fixedly connected to the left side of the first drive box 4. The output end of the first motor 7 is connected to the positive and negative threaded rod 5. A reverse-threaded rod 6 is fixedly connected. A support frame 8 is fixedly connected to the bottom of the slider 5. A lower arc-shaped frame 9 is fixedly connected to the surface of the support frame 8. A sliding groove is provided on the front of the support frame 8, and an upper arc-shaped frame 10 is slidably connected inside the sliding groove. The upper arc-shaped frame 10 and the lower arc-shaped frame 9 work together. A support plate 11 is fixedly connected to the bottom of the first drive box 4. An electric telescopic rod 12 is fixedly connected to the bottom of the support plate 11. A slide rail 13 is fixedly connected to the bottom of the electric telescopic rod 12. A sliding groove is provided at the bottom of the slide rail 13, and the sliding groove is... Both sides are slidably connected to sliding blocks, and the bottom of the sliding blocks is fixedly connected to the top of the upper arc-shaped frame 10. The aforementioned vacuum oil injector body 2 includes a shell, a vacuum pump, vacuum pipelines, an oil storage tank, an oil injection pump, a metering device, and a control system. The vacuum oil injector body 2 is existing common technology and is common knowledge to those skilled in the art, so it will not be described in detail here. Related contents not disclosed in this application, such as the power supply circuits and control mechanisms of various electrical appliances, are common knowledge to those skilled in the art, and will not be described in detail here. In actual use, it can be... A retractable protective sleeve is provided on the surface of the threaded rod 6 and the first threaded rod 15 to prevent debris from adhering to the surface of the screw and affecting its normal operation. The retractable protective sleeve is not shown. The operator adjusts the distance between the two lower arc-shaped frames 9 according to the length of the shock absorber to be oiled. Then the operator puts the shock absorber to be oiled into the lower arc-shaped frame 9. Then the electric telescopic rod 12 extends to drive the slide rail 13 and the upper arc-shaped frame 10 to move down. The upper arc-shaped frame 10 and the lower arc-shaped frame 9 are used to clamp shock absorbers of different diameters.

[0022] refer to Figure 3 The lifting mechanism 3 includes a second drive box 14 fixedly connected to the top of the base 1. A movable column 17 is slidably connected inside the second drive box 14. The bottom of the movable column 17 is fixedly connected to the top of the first drive box 4. A first threaded rod 15 is rotatably connected inside the second drive box 14. The first threaded rod 15 is threadedly connected to the movable column 17. A second motor 16 is fixedly connected to the top of the second drive box 14. The output end of the second motor 16 is fixedly connected to the first threaded rod 15.

[0023] As a technical optimization of this utility model, the second motor 16 in the lifting mechanism 3 drives the first threaded rod 15 to rotate, so that the movable column 17 drives the first drive box 4 to achieve height adjustment, thereby driving the slider 5, support frame 8, lower arc frame 9 and upper arc frame 10 to move up and down, thus adapting to operators of different heights and improving the comfort of the operator.

[0024] refer to Figure 1 Bearings are fixedly connected inside the first drive box 4 and the second drive box 14 respectively, and the outer rings of the bearings are fixedly connected to the first drive box 4 and the second drive box 14 respectively, and the inner rings of the bearings are fixedly connected to the positive and negative thread rods 6 and the first thread rod 15 respectively.

[0025] As a technical optimization of this utility model, the bearing arrangement inside the first drive box 4 and the second drive box 14 effectively reduces the frictional resistance when the positive and negative threaded rods 6 and the first threaded rod 15 rotate, making the adjustment process smoother and reducing energy loss. At the same time, the bearings provide good support and positioning for the threaded rods, preventing them from shifting or shaking due to stress during long-term use, extending the service life of the threaded rods and related components, ensuring the stability of the device's adjustment accuracy, and improving the overall durability of the equipment.

[0026] refer to Figure 4 Rubber pads 18 are fixedly connected to the inner walls of both the upper arc frame 10 and the lower arc frame 9.

[0027] As a technical optimization of this utility model, the rubber pads 18 on the inner walls of the upper arc-shaped frame 10 and the lower arc-shaped frame 9 increase the friction with the surface of the shock absorber, making the clamping more stable and preventing the shock absorber from sliding or rotating during the oil injection process. The soft rubber material avoids hard compression or scratches on the surface of the shock absorber during clamping, protecting the product's appearance and structural integrity. At the same time, the elastic properties of the rubber better conform to the surfaces of shock absorbers of different diameters, improving the adaptability and stability of the clamping and ensuring reliable oil injection.

[0028] refer to Figure 1 The second drive box 14 has a reinforcing frame 20 fixedly connected to both sides, and the reinforcing frame 20 is fixedly connected to the base 1.

[0029] As a technical optimization of this utility model, the reinforcing frames 20 on both sides of the second drive box 14 are fixedly connected to the base 1, which effectively enhances the overall strength and stability of the connection between the second drive box 14 and the base 1. This disperses the force generated by the lifting mechanism 3 during operation and prevents the second drive box 14 from loosening or deforming due to long-term load-bearing or frequent adjustment. This design ensures the durability of the adjustment accuracy of the lifting mechanism 3, maintains the rigidity of the device structure, extends the service life of the equipment, and improves the reliability of the device in high-intensity production environments.

[0030] refer to Figure 1 The top of the base 1 is fixedly connected to a placement pad 19. The top of the placement pad 19 is provided with anti-slip texture. The placement pad 19 is made of silicone material and can temporarily place the shock absorber to be injected with oil.

[0031] As a technical optimization of this utility model, a silicone pad 19 on the top of the base 1 provides a temporary placement space for the shock absorber to be oiled. The silicone material has good elasticity and cushioning properties, preventing the shock absorber from directly contacting the hard base 1 and causing impact damage. The anti-slip texture on the surface prevents the shock absorber from sliding during placement, ensuring operational safety. The silicone material is wear-resistant and aging-resistant, maintaining good performance for a long time, providing operators with a convenient temporary material storage area, reducing accidental damage during material transfer, and improving operational convenience.

[0032] The working principle and usage process of this utility model are as follows: Before use, ensure that all components of the device are in normal condition, check whether the vacuum oil injector body 2 is properly connected to the relevant pipelines, and whether each motor and electric telescopic rod 12 can operate normally. The operator first places the shock absorber to be oiled on the placement pad 19. According to the length of the shock absorber, start the first motor 7. The first motor 7 will drive the threaded rod 6 to rotate. Since the threaded rod 6 is threadedly connected to the slider 5, the slider 5 will slide relative to or towards each other inside the first drive box 4, thereby driving the support frame 8 and the lower arc frame 9 to move. Adjust the distance between the two lower arc frames 9 to match the length of the shock absorber. Then place the shock absorber in the lower arc frame 9. Next, according to the diameter of the shock absorber, operate the electric telescopic rod 12. The extension of the electric telescopic rod 12 will drive the slide rail 13 to move down. The sliding block at the bottom of the slide rail 13 will move with the slide rail 13, thereby driving the upper arc frame 10 to slide down along the slide groove on the front of the support frame 8, thereby clamping the shock absorber.

[0033] After confirming the shock absorber is securely fixed, operate the vacuum oiling machine body 2 to begin oiling the shock absorber. During the oiling process, pay attention to any oil overflow. After oiling is complete, first turn off the vacuum oiling machine body 2, then activate the electric telescopic rod 12 to retract it, causing the upper arc frame 10 to move upward, releasing the clamp on the shock absorber, and remove the oiled shock absorber from the lower arc frame 9. If you need to continue oiling other models of shock absorbers, repeat the above steps of adjusting the spacing of the lower arc frame 9, the height of the upper arc frame 10, and the height of the lifting mechanism 3 to ensure that the device is compatible with the new shock absorber specifications before proceeding with subsequent operations. After use, turn off the power to all motors and the electric telescopic rod 12, and clean the surface of the device, especially the upper arc frame 10, lower arc frame 9, and placement pad 19 to remove any residual oil, keeping the device clean for the next use.
