Description

Technical Field

[0001] The invention relates to the technical field of automobile leaf springs, and in particular to an automobile leaf spring shot blasting device. Background Art

[0002] Shot peening includes shot peening cleaning and shot peening strengthening. Shot peening cleaning, as the name implies, is to remove impurities such as surface oxide scale to improve the appearance quality. Shot peening strengthening is to use a high-speed projectile flow to continuously impact the surface of the workpiece to be strengthened, forcing the target surface and surface layer to undergo the following changes during the cyclic deformation process: 1. The microstructure is modified; 2. The non-uniform plastic deformation outer layer introduces residual compressive stress, and the inner surface layer produces residual tensile stress; 3. The outer surface roughness changes.

[0003] Leaf springs are needed for automobile parts, and leaf springs need to be processed by shot blasting machines before use. This process can improve the fatigue fracture resistance of automobile leaf springs, prevent fatigue failure, plastic deformation and brittle fracture, and improve fatigue life. For example, the patent with announcement number CN218534157U discloses an automobile leaf spring shot blasting device; through the arc-shaped electromagnet inside the cylinder of the device, the arc-shaped electromagnet can be used to adsorb the shot, and when it moves to the top of the leaf spring, the arc-shaped electromagnet is closed, so that the shot falls toward the leaf spring, and is adsorbed again by the arc-shaped electromagnet at the bottom. After repeated operations, the cyclic falling of the shot can be realized; and then through the fixing bolts and clamps on the second fixing plate, the clamps can be used to clamp and fix multiple leaf springs, so that multiple leaf springs can be shot blasted at one time.

[0004] However, when this shot blasting method is used to shot blast a plurality of automobile leaf springs, it is often only possible to shot blast the outer side of the automobile leaf spring, while the other side of the automobile leaf spring cannot be well processed.

[0021] Compared with the prior art, the present invention has at least the following advantages:

[0022] 1. In the present invention, each clamping mechanism clamps an automobile leaf spring, so that multiple automobile leaf springs are clamped in the drum along the length direction of the drum, and then the driving mechanism is controlled to move. The driving mechanism drives the automobile leaf spring to rotate through the clamping mechanism, and at the same time, drives the multiple automobile leaf springs to revolve around the axis of the drum; in this way, the multiple clamping mechanisms can be controlled to face the shot blasting mechanism, and each side of each automobile leaf spring can be shot blasted, so as to increase the coverage of the automobile leaf spring shot blasting and improve the effect of the automobile leaf spring shot blasting.

[0023] 2. In the present invention, the sun gear is fixed, and the planet carrier is driven to rotate by the driving member, and the planet carrier drives multiple planetary gears to revolve around the axis of the drum as the center. At the same time, under the meshing of the planetary gear and the sun gear, the sun gear drives the planetary gear to rotate, so that the clamping mechanism on the planetary gear can be driven to revolve and rotate, thereby realizing the revolution and rotation of the automobile leaf spring in the drum, so as to increase the shot blasting area of ​​the automobile leaf spring, and when the multiple planetary gears are in motion, they will drive the ring gear to rotate, and the ring gear drives the drum to rotate, so that the drum can drive the shot blasting mechanism to rotate around the multiple automobile leaf springs, so as to perform shot blasting on the automobile leaf springs at multiple angles, and further improve the shot blasting effect of the automobile leaf springs.

[0024] 3. In the present invention, two clamping mechanisms on opposite sides cooperate to clamp the automobile leaf spring; the two clamping mechanisms correspond one to one to the two head ends of the automobile leaf spring; the head end of the automobile leaf spring is placed on the bottom plate, and the head end of the automobile leaf spring is abutted against the triggering member, and the head end of the automobile leaf spring is located between the bottom plate and the clamping member, and then the telescopic member is controlled to extend, the telescopic member drives the base to slide toward the automobile leaf spring, and the automobile leaf spring pushes the triggering member to slide toward the direction of the telescopic member, so that the triggering member can drive the clamping member to slide toward the bottom plate through the transmission assembly, thereby abutting against the automobile leaf spring, and the head end of the automobile leaf spring is clamped through the cooperation of the clamping member and the bottom plate. fixed; and through the opposite extrusion of the automobile leaf spring by the clamping mechanisms at both ends, it can effectively prevent the arc-shaped automobile leaf spring from rebounding and deforming, which causes the curvature of the automobile leaf spring to increase, so that the two clamping mechanisms that are pressed against each other play a role in fixing the curvature of the automobile leaf spring; in this way, the two clamping mechanisms can be pressed against each other to simultaneously achieve the two functions of clamping the automobile leaf spring and fixing the curvature of the automobile leaf spring; and by rotating the threaded rod, the position between the pressure pad and the clamping piece can be adjusted, so that the clamping piece can clamp automobile leaf springs of different thicknesses and different curvatures through the pressure pad, which can improve the application range of the automobile leaf spring shot blasting device.

[0025] 4. In the present invention, the bidirectional screw is rotated, and the bidirectional screw drives the two toggle members to move closer to each other, thereby toggling the telescopic member to extend, thereby clamping the automobile leaf spring; and when the bidirectional screw is rotated in the opposite direction, the bidirectional screw can drive the two wave members to move away from each other, thereby toggling the telescopic member to shorten, thereby unlocking the automobile leaf spring; in this way, through the setting of the control mechanism, multiple telescopic members can be controlled simultaneously by rotating the bolt, which greatly simplifies the clamping process of the automobile leaf spring.

[0026] 5. In the present invention, the hydraulic cylinder is controlled to shorten so that the sun gear is separated from the multiple planetary gears. In this way, the planetary carrier can be rotated to adjust the position of the revolution and the angle of rotation of the multiple clamping mechanisms so that the bottom plate is parallel to the horizontal plane. In this way, the automobile leaf spring can be placed on the bottom plate more conveniently, and the automobile leaf spring can be clamped and fixed more conveniently. When the planetary carrier is rotated, the gear ring on the drum is slightly fixed to prevent the drum from rotating when the planetary carrier is rotated, so that the automobile leaf spring cannot be sent into the drum; and when the planetary carrier is rotated, the angle of the planetary gear is adjusted, and the position of the slot can also be adjusted so that the slot is aligned with the corresponding insertion rod. After the position of the revolution and the angle of rotation of the multiple clamping mechanisms are adjusted, the hydraulic cylinder is controlled to continue to shorten, and the sun gear and the limiter are controlled to continue to move so that the insertion rod on the limiter is inserted into the slot on the corresponding planetary gear. In this way, the rotation of the planetary gear, the planetary carrier and the gear ring on the drum can be limited, which is convenient for clamping and fixing the automobile leaf spring.

[0027] 6. In the present invention, the gear ring drives the drum to rotate, so that the drum can drive the storage chamber to rotate around multiple automobile leaf springs, and at the same time drive the impeller to rotate through the power part; when the storage chamber moves to the lower half of the drum, the impeller is controlled to rotate slowly, so that the steel balls in the drum enter the storage chamber through the feed port under the action of gravity, and the slowly rotating impeller can push the steel balls inward, so that more steel balls can be stored in the storage chamber; after the storage chamber moves to the upper half of the drum, the impeller is controlled to rotate at a high speed, so that the steel balls in the storage chamber can be thrown out through the discharge port by centrifugal force, thereby realizing shot blasting treatment of the automobile leaf springs; and the thrown steel balls fall back into the lower half of the drum under the action of gravity, thereby realizing secondary utilization of the steel balls.
