Description

Technical Field

[0001] This utility model relates to the field of shock absorber processing technology, specifically a cutting device for shock absorber production and processing. Background Technology

[0002] Automotive shock absorbers are used to suppress the oscillations caused by the rebound of springs after absorbing shocks, as well as impacts from the road surface. They are widely used in automobiles to accelerate the attenuation of vibrations in the chassis and body, thereby improving the ride comfort. When driving over uneven roads, although the shock-absorbing springs can filter out road vibrations, the springs themselves still reciprocate; the shock absorber is designed to suppress this spring bounce.

[0003] Previously, when cutting automotive shock absorber sleeves, the sleeves were typically positioned on the cutting machine before cutting. However, the current positioning method for shock absorber sleeves is usually to clamp them from the side or press them from the top. This positioning method can lead to poor sleeve positioning during the cutting process, causing the sleeve to shift and affecting the cutting accuracy, resulting in poor performance. Therefore, it is necessary to redesign and modify the cutting device used for shock absorber production to effectively prevent poor positioning of the shock absorber sleeves. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a cutting device for shock absorber production and processing, which has the advantage of high positioning stability of shock absorber sleeves.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for shock absorber manufacturing and processing, comprising a cutting table, a support frame fixedly connected to the back of the cutting table, sleeves fixedly connected to the surface of the support frame, four sleeves, a movable rod slidably connected inside the sleeves, a cutting component fixedly connected to the bottom of the movable rod, a first electric cylinder fixedly connected to the top of the support frame, the output end of the first electric cylinder fixedly connected to the cutting component, a drive box fixedly connected to both sides of the support frame via brackets, a positive and negative threaded rod rotatably connected inside the drive box, movable plates slidably connected to the front and rear sides inside the drive box, and a fixed top of the drive box... A second electric cylinder is fixedly connected, and a movable frame is fixedly connected to the output end of the second electric cylinder. The movable frame is in contact with the drive box, and a fixed frame is fixedly connected to the surface of the movable frame. Movable columns are slidably connected to the front and rear sides inside the fixed frame. The movable columns are in contact with the movable plate, and a mounting block is fixedly connected to the end of the movable column away from the movable plate. The surface of the mounting block is provided with a mounting groove, and a clamping plate is provided inside the mounting groove. A motor is fixedly connected to the front of the drive box, and the output end of the motor is fixedly connected to a threaded rod. The threaded rod is threadedly connected to the movable plate. A tension spring is fixedly connected to the side of the mounting block away from the clamping plate, and the other end of the tension spring is fixedly connected to the fixed frame.

[0006] As a preferred embodiment of the present invention, both sides of the cutting table are provided with sliding grooves, and an adjustment frame is slidably connected inside the sliding grooves. A first threaded rod is threadedly connected inside the adjustment frame, and a cone block is rotatably connected to the surface of the first threaded rod. A rotating handle is fixedly connected to the end of the first threaded rod away from the cone block.

[0007] As a preferred embodiment of this utility model, both sides of the drive box are fixedly connected to limit frames, and the limit frames are in contact with the movable frame.

[0008] As a preferred embodiment of this utility model, the mounting block is provided with bolts inside, the surface of the clamping plate is provided with locking grooves, and the bolts are threadedly connected to the locking grooves.

[0010] As a preferred embodiment of this utility model, a bearing is fixedly connected inside the drive box, and the outer ring of the bearing is fixedly connected to the drive box, while the inner ring of the bearing is fixedly connected to the threaded rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model adopts a combination design of four sleeves and movable rods, providing a stable vertical sliding track for the cutting component, ensuring no lateral deviation during the cutting process and effectively avoiding product scrapping due to cutting path deviation. The direct drive of the first electric cylinder allows for adjustment of the cutting component's vertical movement. The dual-side drive boxes enable synchronous clamping of the shock absorber sleeve. The application of the positive and negative threaded rods allows the movable plates on both sides to move precisely and synchronously, ensuring uniform force on the sleeve during clamping. The replaceable design of the clamping frame allows the device to adapt to shock absorber sleeves of different shapes and sizes. By changing the corresponding clamping frame, effective clamping of round, square, and even irregularly shaped sleeves can be achieved, expanding the applicability of the equipment, reducing equipment procurement costs for enterprises producing multiple types of shock absorbers, and improving equipment utilization. The motor-driven positive and negative threaded rod method greatly improves operating efficiency compared to traditional manual clamping devices.

[0019] 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.

[0020] like Figures 1 to 4 As shown, a cutting device for manufacturing shock absorbers includes a cutting table 1. A support frame 2 is fixedly connected to the back of the cutting table 1. Sleeves 3 are fixedly connected to the surface of the support frame 2. There are four sleeves 3. A movable rod 4 is slidably connected inside the sleeve 3. A cutting assembly 5 is fixedly connected to the bottom of the movable rod 4. A first electric cylinder 6 is fixedly connected to the top of the support frame 2. The output end of the first electric cylinder 6 is fixedly connected to the cutting assembly 5. A drive box 7 is fixedly connected to both sides of the support frame 2 via brackets. A positive and negative threaded rod is rotatably connected inside the drive box 7. Movable plates 9 are slidably connected to the front and rear sides inside the drive box 7. A second electric cylinder 11 is fixedly connected to the top of the drive box 7. The output of the second electric cylinder 11... A movable frame 10 is fixedly connected to the end of the drive box 7. The movable frame 10 is in contact with the drive box 7. A fixed frame 12 is fixedly connected to the surface of the movable frame 10. Movable columns 13 are slidably connected to the front and rear sides inside the fixed frame 12. The movable columns 13 are in contact with the movable plate 9. A mounting block 14 is fixedly connected to the end of the movable column 13 away from the movable plate 9. The surface of the mounting block 14 is provided with a mounting groove, and a clamping plate 15 is provided inside the mounting groove. A motor 8 is fixedly connected to the front of the drive box 7. The output end of the motor 8 is fixedly connected to a threaded rod. The threaded rod is threadedly connected to the movable plate 9. A tension spring 16 is fixedly connected to the side of the mounting block 14 away from the clamping plate 15. The other end of the tension spring 16 is fixedly connected to the fixed frame 12.

[0021] refer to Figure 3 Both sides of the cutting table 1 are provided with sliding grooves, and an adjustment frame 18 is slidably connected inside the sliding grooves. A first threaded rod 20 is threaded inside the adjustment frame 18. A cone block 19 is rotatably connected to the surface of the first threaded rod 20. A rotating handle is fixedly connected to the end of the first threaded rod 20 away from the cone block 19.

[0022] As a technical optimization of this utility model, the support position can be adjusted according to the height of the sleeve by the cooperation of the sliding groove of the cutting table 1 and the adjusting frame 18, so that the axis of the cone block 19 and the axis of the sleeve are on the same horizontal line. The operator rotates the first threaded rod 20, thereby driving the cone block 19 to move until the cone block 19 is in close contact with both sides of the sleeve, and part of the cone block 19 can be inserted into the sleeve, thereby assisting in clamping and positioning the sleeve.

[0023] refer to Figure 2Both sides of the drive box 7 are fixedly connected to limit frames 21, and the limit frames 21 are in contact with the movable frame 10.

[0024] As a technical optimization of this utility model, the drive box 7 and the limiting frame 21 provide guidance for the vertical movement of the movable frame 10, and the precision-machined mating surface ensures no shaking or deviation, thus extending the service life of the equipment.

[0025] refer to Figure 2 The mounting block 14 has a bolt 17 inside, and the surface of the clamping frame 15 has a locking groove. The bolt 17 is threadedly connected to the locking groove.

[0026] As a technical optimization of this utility model, the bolt 17 connection between the mounting block 14 and the clamping frame 15 provides a convenient and reliable fixing method for replacing the clamping frame 15. Through the threaded engagement of the bolt 17 and the locking groove, a uniformly distributed preload force can be generated, ensuring that the clamping frame 15 will not loosen during clamping. This high-strength connection method ensures the stability of the clamping frame 15 when subjected to large clamping forces. This replaceable clamping frame 15 design allows the equipment to quickly adapt to shock absorber sleeves of different specifications and shapes. When different models of shock absorbers need to be processed, the operator only needs to loosen the bolt 17 and then pull the clamping frame 15 until the clamping frame 15 separates from the mounting groove, thereby completing the disassembly of the clamping frame 15. Then, the corresponding clamping frame 15 can be replaced to complete the adjustment of the equipment. At the same time, the universality of the bolt 17 connection method allows enterprises to customize clamping frames 15 of different materials and shapes according to their own needs, further expanding the applicability of the equipment and improving the production flexibility of enterprises.

[0027] refer to Figure 1 Both sides of the top of the cutting table 1 are fixedly connected to support brackets, and the top of the support brackets is arc-shaped.

[0028] As a technical optimization of this utility model, the support brackets on both sides of the top of the cutting table 1 adopt an arc-shaped design, which can provide a stable support foundation for the shock absorber sleeve. The arc-shaped design of the support brackets also makes it easier for operators to place and remove the shock absorber sleeve, improving the convenience of operation and reducing the labor intensity of operators. The support brackets are made of high-strength, wear-resistant materials, which have good wear resistance and a long service life, and can maintain stable support performance during long-term use, reducing the maintenance cost and replacement frequency of the equipment.

[0029] refer to Figure 2 The drive box 7 has a bearing fixedly connected inside, and the outer ring of the bearing is fixedly connected to the drive box 7, while the inner ring of the bearing is fixedly connected to the threaded rod.

[0030] As a technical optimization of this utility model, the bearing installed inside the drive box 7 provides reliable support and a stable rotational foundation for the threaded rod, ensuring that the threaded rod will not wobble or deviate during rotation. The outer ring of the bearing is fixedly connected to the drive box 7, and the inner ring is fixedly connected to the threaded rod. This structural design can effectively reduce the frictional resistance when the threaded rod rotates, improve power transmission efficiency, and reduce the energy consumption of the motor 8. During the high-speed rotation of the threaded rod, the bearing can withstand large radial and axial loads, ensuring the stable operation of the threaded rod and extending its service life.

[0031] The working principle and usage process of this utility model are as follows: When using this utility model, select a matching clamping plate 15 according to the shape and size of the shock absorber sleeve to be cut. Loosen the bolts 17 on the mounting block 14, remove the original clamping plate 15 from the mounting slot, install the appropriate clamping plate 15 into the mounting slot, and then tighten the bolts 17 to fix the clamping plate 15, ensuring that it will not loosen during clamping. Both ends of the shock absorber sleeve to be cut are open.

[0032] Adjusting the support bracket and adjusting frame 18: Place the shock absorber sleeve on the arc-shaped support brackets on both sides of the top of the cutting table 1. According to the height of the sleeve, slide the adjusting frame 18 in the groove of the cutting table 1 so that the axis of the cone block 19 on the adjusting frame 18 is on the same horizontal line as the axis of the sleeve. Then, rotate the first threaded rod 20 to move the cone block 19 until the cone block 19 is in close contact with both sides of the sleeve, and part of the cone block 19 is inserted into the sleeve, completing the initial auxiliary clamping and positioning of the sleeve.

[0033] Start the second electric cylinder 11: Turn on the power to the equipment and start the second electric cylinder 11 on the top of the drive box 7. The output end of the second electric cylinder 11 drives the movable frame 10 to move vertically downward. Under the guidance of the limit frame 21, the movable frame 10 moves stably up and down, thereby driving the fixed frame 12, movable column 13, mounting block 14 and clamping plate frame 15 to move up and down until the clamping plate frame 15 moves to the front and rear sides of the shock absorber sleeve.

[0034] Then, the threaded rod is driven: the motor 8 on the front of the drive box 7 is started, and the output end of the motor 8 drives the threaded rod to rotate. Because the threaded rod is threadedly connected to the movable plate 9, and due to the special design of the threaded rod, the movable plates 9 on both sides can move synchronously towards the center. During the movement, the movable plate 9 pushes the movable column 13, which in turn pushes the mounting block 14 and the clamping frame 15, thus clamping the shock absorber sleeve. At this time, the tension spring 16 is stretched.

[0035] Adjust the height of the cutting assembly 5: Activate the first electric cylinder 6 at the top of the support frame 2. The output end of the first electric cylinder 6 drives the cutting assembly 5 to move vertically downwards along the movable rod 4 inside the sleeve 3. By observation and adjustment, adjust the cutting assembly 5 to a suitable starting position for cutting, ensuring the cutting path is accurate.

[0036] After confirming that the cutting assembly 5 is properly positioned and the sleeve is securely clamped, the cutting assembly 5 is started to perform the cutting operation. During the cutting process, the four sleeves 3 and the movable rod 4 provide a stable vertical sliding track for the cutting assembly 5, ensuring that the cutting assembly 5 will not shift laterally and ensuring cutting accuracy. The cutting assembly 5, the first electric cylinder 6, the second electric cylinder 11, the motor 8, and the positive and negative thread rod are all existing common technologies and are common knowledge to those skilled in the art, and will not be described in detail in this application.
