Description

Technical Field

[0001] This utility model relates to the field of alloy steel shot centrifugation devices, specifically an alloy steel shot centrifugation device. Background Technology

[0002] Alloy steel shot is pellets made from steel wire. Depending on the type of steel wire, it is divided into stainless alloy steel shot, ordinary high-carbon alloy steel shot, and low-carbon alloy steel shot. Most shot blasting machines require surface pretreatment of alloy steel shot. The main working principle is to use the vibration of the vibrating motor to generate centrifugal force, which drives the steel shot to continuously impact inside the device, thereby treating the surface of the steel shot and gradually increasing its hardness.

[0003] In the prior art, such as in CN219945738U, an alloy steel shot centrifugal device is disclosed. It includes a centrifugal base, a centrifugal cylinder, a vibrating motor, and two first springs. The centrifugal cylinder is located inside the centrifugal base, and the vibrating motor is located on one side of the centrifugal cylinder. One end of each of the two first springs is elastically connected to both sides of the centrifugal cylinder. A feeding pipe is fixedly inserted and connected to the other side of the centrifugal cylinder. A first limiting ring is fitted at one end of the centrifugal cylinder. Multiple support rods are arranged inside the first limiting ring. By setting the first limiting ring, second springs, leak-proof ring, elastic pad, and support rods, when the centrifugal cylinder rotates, the multiple second springs will shake along with it. The alloy steel shot inside the centrifugal cylinder will continuously impact the surface of the elastic pad. The interior is mainly composed of many springs arranged laterally. Gravitational potential energy is converted into kinetic energy, which continues to transmit the force in the opposite direction to the alloy steel shot, thereby making the alloy steel shot bounce over a larger range and improving the efficiency of the centrifugal shot blasting process.

[0004] While the aforementioned patents achieve the effect of increasing the bouncing range of steel shot through the design of structures such as springs and elastic pads, they rely solely on a vibration motor to directly drive the centrifuge drum and transmit vibration through the first springs on both sides. This results in a single and linear vibration mode, limiting the amplitude and direction of the steel shot impact. Furthermore, the passive rebound of the elastic pads and the second transverse springs to achieve steel shot impact relies on the conversion of the steel shot's kinetic energy into the spring's potential energy, leading to significant energy loss and uncontrollable rebound direction. Therefore, to address these issues, an alloy steel shot centrifuge device is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, relying solely on a vibration motor to directly drive the centrifuge drum and transmitting vibration through the first springs on both sides results in a single and linear vibration mode, which limits the amplitude and direction of the steel shot impact. Passive rebound via an elastic pad and a second transverse spring achieves steel shot impact, but energy transfer depends on the conversion of the steel shot's kinetic energy into the spring's potential energy, leading to significant energy loss and uncontrollable rebound direction. This invention proposes an alloy steel shot centrifuge device.

The output end of the servo motor is connected to a drive rod. The drive rod is connected to a driven rod via a transmission belt.

A limiting plate is fixed axially symmetrically on the side of the device plate. A transmission gear rod is slidably connected inside the limiting plate. Two quarter gears mesh on both sides of the transmission gear rod.

[0009] Preferably, the vibrating plate forms a hinged transmission mechanism with the connecting rod and the pull rod, the pull rod generates reciprocating motion through the rotation of the centrifugal plate, and the spring plate forms an elastic support structure along the bottom plate and the side of the vibrating plate.

[0010] Preferably, the driving rod and driven rod of the reciprocating assembly rotate synchronously via a transmission belt, and the tooth surfaces of the two quarter gears alternately mesh with the transmission gear rod to drive it to slide back and forth along the limiting plate.

[0011] Preferably, when the drive motor drives the centrifugal plate to rotate via the rotating rod, the pull rod converts the centrifugal force into the axial vibration of the vibrating plate, and the spring plate adjusts the amplitude of the vibration of the vibrating plate.

[0012] Preferably, when the transmission gear rod of the reciprocating assembly reciprocates within the limiting plate, its end periodically impacts the rebound plate, and the rebound plate forms an elastic impact structure with the can lid through a spring.

[0013] Preferably, the vibrating plate of the vibration assembly and the transmission gear rod of the reciprocating assembly work together to cause the steel shot in the centrifuge tank to generate multi-directional accelerated motion under the centrifugal vibration and the impact of the rebound plate.

[0014] The advantages of this utility model are:

[0015] 1. This utility model uses the centrifugal plate of the vibration component to drive the pull rod to generate reciprocating motion. Combined with the structural design of the elastic support of the spring plate, it realizes the function of multi-dimensional centrifugal vibration of steel shot in the centrifugal tank, solves the problem of small impact amplitude and direction distribution, and improves the uniformity of surface treatment.

[0023] 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 scope of protection of the present utility model.

[0024] Please see Figures 1-4 As shown, an alloy steel shot centrifuge device includes a centrifuge tank 1, a connecting plate 2 fixedly connected to the bottom surface of the centrifuge tank 1 on an axisymmetric basis, a vibration assembly 3 fixedly connected to the bottom surface of the connecting plate 2, a tank cover 4 provided on the top surface of the centrifuge tank 1, springs 5 ​​fixedly connected in a rectangular array on the inner top wall of the tank cover 4, a rebound plate 6 fixedly connected to the bottom surface of the springs 5, and a reciprocating assembly 7 fixedly connected on an axisymmetric basis to the adjacent springs 5 ​​on the inner top wall of the tank cover 4; the vibration assembly 3 includes a vibration plate 31 fixed to the bottom surface of the connecting plate 2, a connecting rod 32 fixedly connected to the side of the vibration plate 31, a pull rod 33 rotatably connected to the surface of the connecting rod 32, a centrifuge plate 34 rotatably connected to the other end of the pull rod 33, a rotating rod 35 fixedly connected to the back of the centrifuge plate 34, a rotating rod 35 connected to the output end of a drive motor 36, a drive motor 36 fixed to a placement plate 37 on the bottom surface of the placement plate 37, a base plate 38 fixed to the bottom surface of the placement plate 37, and a connection between the base plate 38 and the vibration plate 31 via a rectangular array of spring plates 39 on the side;

[0025] During operation, when the drive motor 36 starts, its output end drives the rotating rod 35 and the centrifugal plate 34 to rotate. The centrifugal plate 34 is transmitted through the hinge of the pull rod 33 and the connecting rod 32, which converts the rotational centrifugal force into the axial reciprocating vibration of the vibrating plate 31. The vibrating plate 31 is elastically connected to the bottom plate 38 through the rectangular array of spring plates 39 on the side. During the vibration, the deformation of the spring plates 39 is dynamically adjusted with the rotational speed of the centrifugal plate 34, so that the amplitude of the vibrating plate 31 changes adaptively. The vibration of the vibrating plate 31 is transmitted to the centrifuge tank 1 through the connecting plate 2, which drives the steel shot in the tank to generate multi-directional centrifugal motion. Through the dynamic adjustment of the vibration amplitude and direction, the steel shot forms a high-frequency, multi-dimensional impact between the inner wall of the centrifuge tank 1 and the rebound plate 6.

[0026] Furthermore, the reciprocating assembly 7 includes a device plate 71 fixedly connected to the bottom surface of the rebound plate 6. A servo motor 72 is fixed to the back of the device plate 71. The output end of the servo motor 72 is connected to the drive rod 73. The drive rod 73 is connected to the driven rod 75 through the transmission belt 74. The surfaces of the drive rod 73 and the driven rod 75 penetrate the device plate 71 and are respectively fixed with quarter gears 76. A limiting plate 77 is fixed axially symmetrically on the side of the device plate 71. A transmission gear rod 78 is slidably connected inside the limiting plate 77. Two quarter gears 76 are respectively meshed on both sides of the transmission gear rod 78.

[0027] During operation, the servo motor 72 starts and drives the active rod 73 to rotate. The active rod 73 drives the driven rod 75 to rotate synchronously through the transmission belt 74. The quarter gear 76, fixed to one end of the active rod 73 and the driven rod 75, alternately meshes with the tooth surface of the transmission gear rod 78 as it rotates, forcing the transmission gear rod 78 to slide back and forth in a preset direction within the limiting plate 77. During the sliding process, one end of the transmission gear rod 78 periodically impacts the rebound plate 6. After being impacted, the rebound plate 6 converts the impact force into reverse kinetic energy through the elastic deformation of the spring 5, pushing the steel shot to accelerate away from the inner top wall of the can cover 4. At the same time, the speed of the servo motor 72 is adjustable. By controlling the meshing frequency of the quarter gear 76, the impact intensity and rhythm of the transmission gear rod 78 are precisely controlled, so that the steel shot forms a directional acceleration trajectory under the dual action of centrifugal vibration and active impact.

[0028] Furthermore, the vibrating plate 31 forms a hinged transmission mechanism with the connecting rod 32 and the pull rod 33. The pull rod 33 generates reciprocating motion through the rotation of the centrifugal plate 34. The spring plate 39 forms an elastic support structure along the bottom plate 38 and the side of the vibrating plate 31.

[0029] During operation, when the drive motor 36 drives the rotating rod 35 and the centrifugal plate 34 to rotate, the centrifugal plate 34 converts the centrifugal force into the axial reciprocating motion of the vibrating plate 31 through the hinge transmission between the tie rod 33 and the connecting rod 32. The hinge point between the connecting rod 32 and the tie rod 33 changes with the rotation trajectory of the centrifugal plate 34, forcing the vibrating plate 31 to vibrate along the elastic support direction of the spring plate 39. The rectangular array layout of the spring plate 39 disperses the vibration stress and limits the amplitude range of the vibrating plate 31 through its elastic deformation, avoiding structural fatigue fracture caused by high-frequency vibration. This design, through the stability of the hinge transmission and the elastic adjustment of the spring plate 39, ensures that the vibrating plate 31 transmits multidimensional vibration to the centrifuge tank 1 within a controllable amplitude range, improving the uniformity of steel shot impact and energy utilization.

[0030] Furthermore, the driving rod 73 and driven rod 75 of the reciprocating assembly 7 rotate synchronously through the transmission belt 74, and the tooth surfaces of the two quarter gears 76 alternately mesh with the transmission gear rod 78 to drive it to reciprocate along the limiting plate 77.

[0031] During operation, when the servo motor 72 drives the drive rod 73 to rotate, the transmission belt 74 drives the driven rod 75 to rotate synchronously. The quarter gears 76 at the ends of the drive rod 73 and the driven rod 75 alternately mesh with the tooth surfaces of the transmission gear rod 78 with a phase difference. When one side of the quarter gear 76 disengages, the other side immediately engages, forcing the transmission gear rod 78 to slide in the opposite direction within the limiting plate 77. Through the intermittent meshing design of the quarter gear 76, the reciprocating frequency of the transmission gear rod 78 is linearly related to the rotational speed of the servo motor 72, achieving precise control of the impact rhythm. This synchronous drive structure avoids motion interference caused by continuous meshing of traditional gears, significantly improving the response speed and directional consistency of reciprocating impacts.

[0032] Furthermore, when the drive motor 36 drives the centrifugal plate 34 to rotate via the rotating rod 35, the pull rod 33 converts the centrifugal force into the axial vibration of the vibrating plate 31, and the spring plate 39 adjusts the amplitude of the vibration of the vibrating plate 31.

[0033] During operation, when the drive motor 36 drives the centrifugal plate 34 to rotate at high speed through the rotating rod 35, the eccentric mass of the centrifugal plate 34 generates centrifugal force, which forces the tie rod 33 to pull the vibrating plate 31 axially with the hinge point as the fulcrum. The displacement of the vibrating plate 31 is determined by the rotational speed of the centrifugal plate 34 and the stiffness of the spring plate 39. The spring plate 39 absorbs vibration energy and limits the vibration amplitude through lateral elastic deformation to prevent vibration overload. This design directly converts the rotational centrifugal force into axial vibration energy. Combined with the dynamic adjustment of the spring plate 39, it achieves the matching optimization of vibration frequency and amplitude, so that the steel shot obtains a high-frequency and uniform centrifugal acceleration effect in the centrifuge tank 1.

[0034] Furthermore, when the transmission gear rod 78 of the reciprocating assembly 7 reciprocates within the limiting plate 77, its end periodically impacts the rebound plate 6, and the rebound plate 6 forms an elastic impact structure with the can lid 4 through the spring 5.

[0035] During operation, when the transmission gear rod 78 reciprocates within the limiting plate 77, its end impacts the rebound plate 6 at a preset stroke cycle. After being impacted, the rebound plate 6 buffers the impact force through the elastic deformation of the spring 5 and converts some of the kinetic energy into a reverse elastic force. The rectangular array layout of the spring 5 evenly disperses the impact stress, avoiding excessive local deformation. At the same time, the elastic reset of the rebound plate 6 ensures that it quickly returns to its initial position after each impact. This structure, through the synergistic effect of active impact and elastic rebound, efficiently converts the mechanical energy output by the servo motor 72 into the directional kinetic energy of the steel shot, reducing energy loss and enhancing the controllability of the steel shot's trajectory.

[0036] Working principle: After the drive motor 36 starts, its output end drives the centrifugal plate 34 to rotate at high speed through the rotating rod 35. The eccentric mass of the centrifugal plate 34 generates centrifugal force, which drives the tie rod 33, which is hinged to it, to reciprocate. The tie rod 33 transmits the reciprocating motion to the vibrating plate 31 through the connecting rod 32. The vibrating plate 31 is elastically connected to the bottom plate 38 through the rectangular array of spring plates 39 on the side. Under the centrifugal force and the deformation adjustment of the spring plates 39, multi-directional vibration is formed, and the vibration is transmitted to the centrifuge tank 1 through the connecting plate 2, so that the steel shot in the tank is accelerated along the inner wall in multiple directions under the action of centrifugal vibration. At the same time, the servo motor 72 drives the active rod 73 to rotate, and the reciprocating motion is transmitted through the connecting rod 32 to the centrifuge tank 1. The driven rod 75 is driven to rotate synchronously by the transmission belt 74. The quarter gear 76 at the end of the driving rod 73 and the driven rod 75 alternately meshes with the transmission gear rod 78, forcing the transmission gear rod 78 to slide back and forth in the limiting plate 77 and periodically impact the rebound plate 6. After being impacted, the rebound plate 6 converts the impact force into reverse kinetic energy through the elastic deformation of the spring 5, pushing the steel shot away from the inner top wall of the tank cover 4 and forming a compound motion path with the vibration of the centrifugal tank 1. The multidimensional vibration of the vibration component 3 and the active impact of the reciprocating component 7 work together to make the steel shot impact the tank body at high frequency under multiple accelerations of centrifugation, vibration and rebound impact, so as to achieve a uniform improvement in surface hardness.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
