[0022] As Figures 1-4As shown in the figure, the utility model provides a technical solution: an anti-slip-off automotive suspension spring compression device, which includes a retraction cylinder 1. The piston of the retraction cylinder 1 is connected to a piston rod 2. A plug 3 is fixed on the upper surface of the piston rod 2. The piston rod 2 passes through a limit block 4 and is slidably connected at the penetration point. The lower surface of the plug 3 is fixedly connected to the upper limit block 4. The limit block 4 is fixed with a clamping mechanism 5 for conveniently clamping the automotive suspension spring. The clamping mechanism 5 is provided with a protection mechanism 6 for preventing the automotive suspension spring from flying out.
[0023] The above-mentioned clamping mechanism 5 includes a limiter 51, a threaded rod 52, a rotating block 53, a connecting rod 54, a driving block 55, a guiding strip 56, a guiding groove 57, a clamping jaw 58 and a groove 59. The limiter 51 is fixedly installed between two groups of limit blocks 4. The threaded rod 52 passes through the limiter 51 and is threadedly connected at the penetration point. Since the limiter 51 is fixed, when the threaded rod 52 rotates, it moves back and forth by itself. The rotating block 53 is fixedly installed at the left end of the threaded rod 52. By rotating the rotating block 53, the rotating block 53 drives the threaded rod 52 to rotate. The right end of the threaded rod 52 rotates a connecting rod 54. When the threaded rod 52 rotates, it pushes the connecting rod 54 to move. One end of the connecting rod 54 away from the threaded rod 52 is fixed with a driving block 55. The movement of the connecting rod 54 drives the driving block 55 to move. A guiding strip 56 is fixed on the side wall of the driving block 55. A guiding groove 57 is opened on the inner wall of the limiter 51. The guiding strip 56 and the guiding groove 57 are slidably connected to a clamping jaw 58. The movement of the driving block 55 drives the clamping jaw 58 to slide along the guiding strip 56 and the guiding groove 57. A groove 59 is opened on the side wall of the clamping jaw 58. The two clamping jaws 58 approach each other, so that the topmost coil of the automotive suspension spring is stuck into the groove 59. The clamping mechanism 5 can drive the clamping jaw 58 to clamp or release by rotating the rotating block 53, and the automotive suspension spring is stuck into the groove 59, making the clamping more stable.
[0024] The above-mentioned protection mechanism 6 includes a linkage rod 61, a left protection plate 62, a right protection plate 63, a first hinge rod 64 and a second hinge rod 65. The linkage rod 61 is fixedly installed on the upper surface of the lower driving block 55. The movement of the driving block 55 drives the linkage rod 61 to move. The left protection plate 62 slides on the upper surface of the lower limiter 51. The right protection plate 63 slides on the upper surface of the lower limiter 51. The front surface of the left protection plate 62 is hinged with a first hinge rod 64. The rotation of the first hinge rod 64 drives the left protection plate 62 to slide. The front surface of the right protection plate 63 is hinged with a second hinge rod 65. The rotation of the second hinge rod 65 drives the right protection plate 63 to slide. The linkage rod 61 passes through the first hinge rod 64 and the second hinge rod 65 and is rotatably connected at the penetration point. The movement of the linkage rod 61 drives the first hinge rod 64 and the second hinge rod 65 to rotate. The protection mechanism 6 can cover the automotive suspension spring on all sides while clamping the automotive suspension spring, avoiding the automotive suspension spring from flying out obliquely due to uneven force during the compression process.
[0025] Working principle: Rotate the rotating block 53, the rotating block 53 drives the threaded rod 52 to rotate, the threaded rod 52 rotates to push the connecting rod 54 to move, the connecting rod 54 moves to drive the driving block 55 to move, the driving block 55 moves to drive the clamping jaw 58 to slide along the guide bar 56 and the guide groove 57, and the two groups of clamping jaws 58 approach each other, so that the topmost coil of the automotive suspension spring is clamped into the groove 59, then the automotive suspension spring can be clamped, and the topmost and bottommost layers of the automotive suspension spring are clamped. Start the contraction cylinder 1 to compress the automotive suspension spring.
[0026] When clamping the bottommost layer of the automotive suspension spring, the driving block 55 drives the linkage rod 61 to move, the linkage rod 61 moves to drive the first hinge rod 64 to rotate, the first hinge rod 64 rotates to drive the left protective plate 62 to slide, and at the same time the linkage rod 61 drives the second hinge rod 65 to rotate, the second hinge rod 65 rotates to drive the right protective plate 63 to slide, and the left protective plate 62 and the right protective plate 63 approach each other to cover the automotive suspension spring.
[0027] The above has generally described the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
