Description

Technical Field

[0001] This utility model belongs to the field of automotive suspension spring technology, and in particular relates to a cutting device for the processing and manufacturing of automotive suspension springs. Background Technology

[0002] Automotive suspension springs are an important component of the automotive suspension system. Their main function is to support the weight of the vehicle body, mitigate impacts from the road surface, and ensure the stability and comfort of the vehicle. During vehicle operation, suspension springs can absorb vibrations from the road surface, reduce impacts on the vehicle body, and protect the vehicle structure from damage.

[0003] During the production of automotive suspension springs, in order to change the spring strength, improve suspension performance, and adapt to different load requirements, automotive suspension springs are often cut. A cutting machine is used to cut automotive suspension springs. However, existing cutting machines lack corresponding positioning components, which may cause misalignment during cutting due to deformation of the suspension spring, affecting its use. The problem with this technology is that the automotive suspension spring deforms during cutting, leading to misalignment. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a cutting device for the processing and manufacturing of automobile suspension springs that can overcome the above problems or at least partially solve the above problems.

The output end of the left side of the first cylinder is fixedly connected to the right side of the connecting block.

[0006] The cutting machine is used to cut off automobile suspension springs;

[0007] The positioning component is used to position and fix the vehicle suspension springs.

[0008] To facilitate the installation or removal of automotive suspension springs, preferably, limit blocks are fixedly connected to both the left and right sides of the bottom of the workbench, and the surfaces of the two limit blocks are slidably connected to the bottom of the cutting box. A pressing component is provided on the top of the workbench, and a moving component is provided inside the control box. By moving the workbench forward, the front side of the positioning component moves during the movement of the workbench, causing the positioning component to move out of the cutting box, thereby facilitating the installation or removal of automotive suspension springs.

[0009] To clamp and fix the automotive suspension spring, preferably, the pressing assembly includes a bracket, two pressing springs, and a pressing plate. The bottom of the bracket is fixedly connected to the front side of the top of the worktable. The side of the worktable near the two pressing springs is fixedly connected to the bottom of the two pressing springs. The tops of the two pressing springs are fixedly connected to the left and right sides of the bottom of the pressing plate, respectively. The side of the bracket near the pressing plate is slidably connected to the inside of the pressing plate. By activating the first cylinder, the output end of the first cylinder drives the connecting block to move to the left. During the movement of the connecting block, multiple top blocks move in the opposite direction. During the movement of the multiple top blocks, they make close contact with the inside of the automotive suspension spring. The two pressing springs generate a downward pulling force on the pressing plate. The bracket keeps the pressing plate in a stable position, so that the bottom of the pressing plate makes close contact with the surface of the automotive suspension spring, thereby clamping and fixing the automotive suspension spring.

[0010] To facilitate the cutting of automotive suspension springs, preferably, the moving assembly includes a lead screw motor, a moving plate, and a moving rod.

[0011] To prevent misalignment when the cutting disc cuts the car suspension springs, preferably, a slider is fixedly connected to the left side of the output end of the cutting motor, and a sliding rod is slidably connected inside the slider. The front side of the sliding rod is fixedly connected to the left side of the front side inside the cutting box, and the rear side of the sliding rod is fixedly connected to the left side of the rear side inside the cutting box. During the movement of the cutting motor, the slider slides on the surface of the sliding rod, thereby limiting the position of the output end of the cutting motor, stabilizing the movement of the output end of the cutting motor, preventing the output end of the cutting motor from tilting, and thus keeping the cutting disc stable.

[0012] To keep the worktable stable inside the cutting box, preferably, a fixing spring is fixedly connected to the front side of the top of the worktable, and a protrusion is fixedly connected to the bottom of the fixing spring. The surface of the protrusion is slidably connected to the front side of the worktable, and the bottom of the protrusion is movably connected to the inside of the cutting box. By inserting the protrusion into the inside of the cutting box, the fixing spring plays the role of keeping the protrusion stable and restricting the movement of the worktable, thereby keeping the worktable stable inside the cutting box.

[0013] To prevent the car suspension spring from shifting to the left or right, preferably, a second cylinder is fixedly connected to the left side of the cutting box, a push plate is fixedly connected to the right side of the output end of the second cylinder, and a pressure sensor is fixedly connected to the right side of the push plate.

[0022] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0023] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 5As shown in the figure, the present invention provides a cutting device for processing and manufacturing automotive suspension springs, including a cutting machine 1 and a positioning assembly 2. The cutting machine 1 includes a control box 1a, a cutting box 1b, a cutting motor 1c, a cutting disc 1d, and a worktable 1e. The left side of the control box 1a is fixedly connected to the right side of the cutting box 1b. The cutting motor 1c is installed inside the control box 1a on the left side. The inside of the cutting disc 1d is fixedly connected to the surface of the output end of the cutting motor 1c. The bottom of the worktable 1e is movably connected to the bottom inside the cutting box 1b. The positioning assembly 2 includes a fixed sleeve 2a, multiple top blocks 2b, connecting blocks 2c, two connecting discs 2d, and a first cylinder 2e. The surfaces of the multiple top blocks 2b are all slidably connected to the inside of the fixed sleeve 2a. The internal components of the cutting machine 1 are slidably connected to the surface of the connecting block 2c. The bottom left side of the left connecting plate 2d is fixedly connected to the right side of the worktable 1e. The left side of the left connecting plate 2d is fixedly connected to the right side of the fixing sleeve 2a. The right side of the right connecting plate 2d is fixedly connected to the left side of the first cylinder 2e. The output end of the left side of the first cylinder 2e is fixedly connected to the right side of the connecting block 2c. The cutting machine 1 is used to cut the car suspension spring. The positioning component 2 is used to position and fix the car suspension spring. In order to facilitate the installation or removal of the car suspension spring, the left and right sides of the bottom of the worktable 1e are fixedly connected to the limit blocks 3. The surfaces of the two limit blocks 3 are slidably connected to the bottom of the inside of the cutting box 1b. The top of the worktable 1e is provided with a pressing component 4. The inside of the control box 1a is provided with... A movable component 5 is provided. By moving the worktable 1e forward, the front side of the positioning component 2 moves during the movement of the worktable 1e, causing the positioning component 2 to move out of the interior of the cutting box 1b, thereby facilitating the installation or removal of the automotive suspension spring. In order to clamp and fix the automotive suspension spring, the pressing component 4 includes a bracket 401, two pressing springs 402, and a pressing plate 403. The bottom of the bracket 401 is fixedly connected to the front side of the top of the worktable 1e. The side of the worktable 1e near the two pressing springs 402 is fixedly connected to the bottom of the two pressing springs 402. The top of the two pressing springs 402 is fixedly connected to the left and right sides of the bottom of the pressing plate 403, respectively. The side of the bracket 401 near the pressing plate 403 slides inside the pressing plate 403. The connection is achieved by activating the first cylinder 2e. The output end of the first cylinder 2e drives the connecting block 2c to move to the left. During the movement of the connecting block 2c, multiple top blocks 2b move in the opposite direction. During the movement of the multiple top blocks 2b, they make close contact with the inside of the car suspension spring. The two downward pressure springs 402 generate a downward pulling force on the lower pressure plate 403. The bracket 401 keeps the lower pressure plate 403 in a stable position, so that the bottom of the lower pressure plate 403 makes close contact with the surface of the car suspension spring, thereby clamping and fixing the car suspension spring. In order to facilitate the cutting of the car suspension spring, the moving assembly 5 includes a lead screw motor 501, a moving plate 502, and a moving rod 503. The rear side of the lead screw motor 501 is fixedly connected to the rear side inside the control box 1a.The front side of the output end of the lead screw motor 501 is movably connected to the front side inside the control box 1a. The surface of the output end of the lead screw motor 501 is threadedly connected to the bottom of the moving plate 502. The bottom of the cutting motor 1c is fixedly connected to the top of the moving plate 502. The rear side of the moving rod 503 is fixedly connected to the front side of the lead screw motor 501. The side of the control box 1a near the moving rod 503 is fixedly connected to the front side of the moving rod 503. The surface of the moving rod 503 is slidably connected to the right side inside the moving plate 502. By starting the lead screw motor 501, the output end of the lead screw motor 501 rotates, driving the moving plate 502 forward. The right side of the moving plate 502 slides on the surface of the moving rod 503, keeping the moving plate 502 stable. During the movement of the moving plate 502, the cutting motor 1c moves, which in turn moves the cutting disc 1d, thus cutting the automotive suspension spring. To prevent misalignment when the cutting disc 1d cuts the automotive suspension spring, a slider 6 is fixedly connected to the left side of the output end of the cutting motor 1c. A sliding rod 7 is slidably connected inside the slider 6. The front side of the sliding rod 7 is fixedly connected to the left side of the front of the cutting box 1b, and the rear side of the sliding rod 7 is fixedly connected to the left side of the rear of the cutting box 1b. During the movement of 1c, slider 6 slides on the surface of slider 7, thereby limiting the position of the output end of cutting motor 1c, stabilizing the movement of the output end of cutting motor 1c, preventing the output end of cutting motor 1c from tilting, and thus keeping cutting disc 1d stable. To keep worktable 1e stable inside cutting box 1b, a fixing spring 8 is fixedly connected to the front side of the top of the inside of worktable 1e. A protrusion 9 is fixedly connected to the bottom of fixing spring 8. The surface of protrusion 9 is slidably connected to the front side of the inside of worktable 1e, and the bottom of protrusion 9 is movably connected to the inside of cutting box 1b. The protrusion 9 is inserted into the inside of cutting box 1b to secure the worktable. The fixed spring 8 serves to stabilize the protrusion 9 and restrict the movement of the worktable 1e, thereby keeping the worktable 1e stable inside the cutting box 1b. To prevent the automotive suspension spring from shifting to the left or right, a second cylinder 10 is fixedly connected to the left side of the cutting box 1b. A push plate 11 is fixedly connected to the right side of the output end of the second cylinder 10, and a pressure sensor 12 is fixedly connected to the right side of the push plate 11. By activating the second cylinder 10, the output end of the second cylinder 10 drives the push plate 11 to move to the right. After the pressure sensor 12 contacts the automotive suspension spring, the second cylinder 10 stops operating, thus restricting the movement of the automotive suspension spring.

[0025] The working principle of this utility model:

[0026] When cutting the car suspension spring, pull the protrusion 9 upward. During the movement of the protrusion 9, the fixed spring 8 deforms. After the bottom of the protrusion 9 disengages from the cutting box 1b, the worktable 1e moves forward. After the worktable 1e moves to the front, the lower pressure plate 403 moves upward. During the movement of the lower pressure plate 403, the two lower pressure springs 402 deform, putting the car suspension spring onto the surface of the fixed sleeve 2a, so that the right side of the car suspension spring is in close contact with the left side of the left connecting plate 2d. The first cylinder 2e is activated. The output end of the first cylinder 2e drives the connecting block 2c to move to the left. During the movement of the connecting block 2c, multiple top blocks 2b move in the opposite direction. After the multiple top blocks 2b are in close contact with the inside of the car suspension spring, the first cylinder 2e is closed, the lower pressure plate 403 is released, the two lower pressure springs 402 rebound, and the lower pressure plate 403 moves downward. The bottom of the lower pressure plate 403 is in contact with the top of the car suspension spring. The worktable 1e is moved backward and the fixed spring 8 rebounds, causing the protrusion 9 to insert into the cutting box 1b, thus stabilizing the worktable 1e. The second cylinder 10 is started, and its output end drives the push plate 11 to move to the right. After the pressure sensor 12 contacts the car suspension spring, the second cylinder 10 stops running, thus restricting the movement of the car suspension spring. The cutting motor 1c and the lead screw motor 501 are started. The cutting motor 1c drives the cutting disc 1d to rotate. During the rotation of the output end of the lead screw motor 501, the moving plate 502 moves forward. The right side of the moving plate 502 slides on the surface of the moving rod 503, keeping the moving plate 502 stable. During the movement of the moving plate 502, the cutting motor 1c moves, and the cutting disc 1d moves, thus cutting the car suspension spring.
