Description

Technical Field

[0001] This invention relates to the field of shot blasting technology for automotive parts, and more particularly to a shot blasting device and method for automotive parts. Background Technology

[0002] Shot blasting for automotive parts is a specialized equipment that uses high-speed abrasive to impact and grind the surface of automotive parts. Its core function is to remove surface oxide scale, rust, or oil stains.

[0003] Patent CN220533943U relates to a shot blasting device for processing automotive parts, belonging to the field of automotive parts processing technology. It includes a housing with two second motors symmetrically installed on both sides of the outer wall. Before shot blasting, the operator places the parts between two push plates and activates the first electric telescopic rod, causing the two push plates to move closer together until they clamp the parts. During shot blasting, the third motor is activated, causing the first electric telescopic rod and push plates to rotate the parts, resulting in more uniform shot blasting. After shot blasting, the second electric telescopic rod is activated, extending its telescopic ends and pushing two fixed seats to the side of the parts. Then, the fourth motor is activated, causing the second threaded rod to rotate, bringing the two clamping plates closer together until they clamp the parts. The two push plates then move away from the parts, and the second motor is activated again, causing the parts to rotate and continue shot blasting, ensuring that all surfaces of the parts can be shot blasted.

[0004] In the aforementioned patent, two clamping plates are brought close together until they hold the component, and then two push plates are released from the component. The second motor is started, the component rotates, and shot blasting continues, ensuring that all surfaces of the component can be shot blasted. However, the abrasive projection range of the shot blasting equipment is a fixed fan-shaped area. The abrasive density is high in the area of ​​the workpiece close to the shot blasting equipment, while the abrasive density is sparse in the area far away or at the edge, resulting in uneven shot blasting effect. Therefore, it is necessary to design a shot blasting device for automotive parts to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a shot blasting device and method for automotive parts.

The free end of the elastic telescopic rod moves downwards to reset, causing the turntable to move downwards, and the downward movement of the turntable causes the workpiece to move downwards.

[0007] As a preferred embodiment of the present invention, the bottom side of the support frame is set as an arc surface. By setting the bottom side of the support frame as an arc surface, the frictional force when the support frame contacts the connecting plate can be reduced. The workpiece abuts against the support ring. The bottom of the free end of the elastic telescopic plate is set as an inclined surface. The support ring is limited by the unidirectional movement of the elastic telescopic plate and cannot move towards the support frame.

[0008] As a preferred embodiment of the present invention, the free end of the elastic telescopic plate abuts against the limiting hole, the top of the shot blasting frame is provided with a shot blasting port, and the bottom of the shot blasting frame is provided with a servo motor and the output end of the servo motor is fixedly connected to the bottom of the elastic telescopic rod.

[0009] As a preferred embodiment of the present invention, it further includes a separation component and a recovery component. The separation component is used to separate impurities and abrasives, and the recovery component is used to improve the recovery efficiency of impurities. The separation component includes a separation plate, a separation frame, a separation spring, a load-bearing frame, and a load-bearing ring. The separation plate moves up and down to shake the abrasives and impurities on the top of the separation plate. The separation plate is slidably installed on the inner wall of the shot blasting frame, and the separation frame is fixedly installed on the inner wall of the shot blasting frame. The separation spring is disposed between the separation plate and the separation frame, and can support the separation plate through the separation spring. The load-bearing frame is fixedly installed on the top of the separation plate, and the load-bearing ring is fixedly installed on the top of the load-bearing frame. The top of the separation plate has a separation hole.

[0010] As a preferred embodiment of the present invention, the separation assembly further includes a rubber ring and a rubber opening. The rubber ring is disposed between the separation plate and the separation frame, and the rubber opening is opened on the circumferential surface of the rubber ring. The load-bearing ring is in contact with the elastic telescopic rod, and the separation plate is subjected to the reaction force of the rubber ring and the buffering effect of the rubber ring.

[0011] As a preferred embodiment of the present invention, the top of the load-bearing frame is provided with a load-bearing hole, the front side of the load-bearing frame is provided with an inclined surface, and the front and rear sides of the separation frame are provided with connecting holes. When the separation plate moves downward, it will squeeze the rubber ring.

[0012] As a preferred embodiment of the present invention, the recycling assembly includes a disintegration frame, a disintegration plate, a connecting plate, a disintegration spring, a shaking plate, and a shaking block. The disintegration plate moves upward, causing the disintegration frame to move upward. The disintegration frame moves back and forth and rotates to break up falling impurities. The disintegration frame is slidably mounted on the circumferential surface of the elastic telescopic rod. The disintegration plate is fixedly mounted on the bottom of the disintegration frame. The connecting plate is fixedly mounted on the circumferential surface of the elastic telescopic rod. A disintegration spring is provided between the connecting plate and the disintegration plate to support the disintegration frame. The shaking plate is fixedly mounted on the bottom of the separation frame, and the shaking block is fixedly mounted on the circumferential surface of the disintegration frame.

[0013] As a preferred embodiment of the present invention, the shaking plate is elastic, and the elasticity of the shaking plate can drive the shaking block to shake. The disassembly frame abuts against the separation plate, the disassembly frame contacts the shaking plate, and the rotation of the shaking block will strike the shaking plate.

[0014] A shot blasting method using a shot blasting apparatus for automotive parts, comprising the following steps: Step 1: The support ring moves towards the workpiece and contacts it, squeezing and limiting the workpiece. After the workpiece is stable, the servo motor is started to drive the elastic telescopic rod to rotate. Step 2: The rotation of the elastic telescopic rod drives the connecting plate to rotate. The rotating connecting plate contacts the arc surface of the support frame and squeezes the support frame. The connecting plate moves upward due to the reaction force of squeezing the support frame. Step 3: The connecting plate moves upward, causing the free end of the elastic telescopic rod to move upward. The upward movement of the free end of the elastic telescopic rod causes the turntable and the workpiece to move upward. After the connecting plate continues to rotate and disengages from the support frame, the free end of the elastic telescopic rod moves downward to reset under its own elastic force. Step 4: The free end of the elastic telescopic rod moves downward to reset, causing the turntable to move downward. The downward movement of the turntable causes the workpiece to move downward. As the workpiece moves back and forth, the shot blasting equipment is started to perform shot blasting operations.

[0015] The present invention has the following beneficial effects: 1. This invention prevents the workpiece from tilting during shot blasting by unidirectionally limiting the support ring to prevent it from moving towards the support frame. Tilting the workpiece would directly cause its position to shift and its posture to become skewed, blocking the originally preset blasting area. The unidirectional limiting can fix the position of the workpiece, keeping it within the preset blasting range. The downward movement of the turntable causes the workpiece to move downward, making it move and rotate back and forth. The turntable drives the workpiece to rotate and move back and forth, allowing the abrasive to fully impact the workpiece, avoiding oxide scale residue on the workpiece surface, thereby ensuring consistent surface roughness and improving the effect of shot blasting.

[0016] 2. This invention improves the separation effect of abrasive and impurities by moving the separation plate up and down to shake the abrasive and impurities on the top of the separation plate. The efficient separation can reduce the situation of impurities being mistakenly screened out, thereby improving the recycling rate of abrasive, reducing the frequency of abrasive replenishment, and thus indirectly reducing equipment maintenance costs.

[0017] 3. In this invention, the separating plate is subjected to the reaction force of the rubber ring and the buffering effect of the rubber ring. The elastic buffering of the rubber ring can reduce the structural fatigue caused by high-frequency vibration, avoid bending or deformation problems after long-term use, thereby ensuring the flatness of the separating plate, and at the same time reducing the situation where qualified abrasive is mistakenly screened out along with impurities due to the deformation of the separating plate.

[0018] 4. This invention breaks down falling impurities by moving and rotating the shot blasting frame back and forth, thereby preventing oil stains and impurities from sticking together. The back-and-forth rotation of the shot blasting frame breaks down lumpy impurities that are stuck together with oil stains, preventing them from adhering to the inner wall of the shot blasting frame, reducing incomplete cleaning caused by impurities sticking together, and thus improving the continuity of shot blasting operations.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Reference Figure 1-6 One embodiment of the present invention is: a shot blasting device for automotive parts, including a shot blasting frame 1 and a shot blasting device, and further including a movement limiting component. The shot blasting frame 1 has a discharge port 2 on its front side. An elastic telescopic rod 3 rotatably passes through the bottom of the shot blasting frame 1. A support frame 4 is fixedly installed on the inner wall of the shot blasting frame 1. A turntable 5 is fixedly installed on the free end of the elastic telescopic rod 3. A workpiece 11 is disposed on the top of the turntable 5. The shot blasting device is disposed on the top of the shot blasting frame 1. The movement limiting component includes a support frame 6, a support ring 7, a support spring 8, an elastic telescopic plate 9, a limiting hole 10, and a connecting plate 12. The support frame 6 is fixedly installed on the inner wall of the shot blasting frame 1. The support ring 7 is slidably mounted on the top of the turntable 5. The support spring 8 is set between the support frame 6 and the support ring 7. The support ring 7 can be supported by the support spring 8. The elastic telescopic plate 9 is fixedly installed at the bottom of the support ring 7. The limiting hole 10 is opened on the top of the turntable 5. The connecting plate 12 is fixedly installed on the circumferential surface of the free end of the elastic telescopic rod 3. The turntable 5 drives the workpiece 11 to rotate and reciprocate, which can allow the abrasive to fully impact the workpiece 11, avoid oxide scale residue on the surface of the workpiece 11, thereby ensuring consistent surface roughness and improving the effect of shot blasting.

[0023] The bottom side of the support frame 4 is set as an arc surface. By setting the bottom side of the support frame 4 as an arc surface, the friction force when the support frame 4 contacts the connecting plate 12 can be reduced. The workpiece 11 abuts against the support ring 7. The bottom of the free end of the elastic telescopic plate 9 is set as an inclined surface. The support ring 7 is limited by the one-way limit of the elastic telescopic plate 9 and cannot move towards the support frame 6. The one-way limit can fix the position of the workpiece 11 and keep it always within the preset projection range.

[0024] The free end of the elastic telescopic plate 9 abuts against the limiting hole 10. The top of the shot blasting frame 1 is provided with a shot blasting port. The bottom of the shot blasting frame 1 is provided with a servo motor and the output end of the servo motor is fixedly connected to the bottom of the elastic telescopic rod 3.

[0025] A shot blasting method using a shot blasting apparatus for automotive parts, comprising the following steps: Step 1: The support ring 7 moves towards the workpiece 11 and contacts the workpiece 11, squeezing and limiting the workpiece 11. After the workpiece 11 is stable, the servo motor is started to drive the elastic telescopic rod 3 to rotate. Step 2: The elastic telescopic rod 3 rotates, causing the connecting plate 12 to rotate. The connecting plate 12 rotates and contacts the arc surface of the support frame 4, pressing the support frame 4. The connecting plate 12 moves upward due to the reaction force of the pressing support frame 4. Step 3: The connecting plate 12 moves upward, causing the free end of the elastic telescopic rod 3 to move upward. The upward movement of the free end of the elastic telescopic rod 3 causes the turntable 5 and the workpiece 11 to move upward. After the connecting plate 12 continues to rotate and disengages from the support frame 4, the free end of the elastic telescopic rod 3 moves downward and resets under its own elastic force. Step 4: The free end of the elastic telescopic rod 3 moves downward to reset, which drives the turntable 5 to move downward. The downward movement of the turntable 5 drives the workpiece 11 to move downward. The workpiece 11 moves back and forth, and at the same time, the shot blasting equipment is started to perform shot blasting operation.

[0026] During operation: Manually pull the support ring 7 towards the support frame 6. This movement compresses the support spring 8, causing it to deform and store force. Simultaneously, place the workpiece 11 on top of the turntable 5. Once the workpiece 11 is on top, release the support ring 7, allowing it to move towards the workpiece 11 under the elastic force of the support spring 8. The support ring 7 contacts and compresses the workpiece 11, limiting its movement. Simultaneously, the movement of the support ring 7 moves the elastic telescopic plate 9, aligning its free end with the limiting hole 10. After alignment, the free end of the elastic telescopic plate 9 moves downwards under its own elastic force, resetting to contact the inner wall of the limiting hole 10 and providing unidirectional limitation for the support ring 7. The support ring 7 is thus unidirectionally limited by the elastic telescopic plate 9. The workpiece 11 is prevented from moving towards the support frame 6 by a limit switch, thus preventing it from tipping over during shot blasting. After the workpiece 11 is stabilized, a servo motor is installed at the bottom of the shot blasting frame 1, and the output end of the servo motor is fixedly connected to the bottom of the elastic telescopic rod 3. The servo motor is started to drive the elastic telescopic rod 3 to rotate. The rotation of the elastic telescopic rod 3 drives the connecting plate 12 to rotate. The rotating connecting plate 12 contacts the arc surface of the support frame 4 and squeezes the support frame 4. The connecting plate 12 moves upward due to the reaction force of the squeezed support frame 4. The upward movement of the connecting plate 12 drives the free end of the elastic telescopic rod 3 to move upward. The upward movement of the free end of the elastic telescopic rod 3 drives the turntable 5 and the workpiece 11 to move upward. After the connecting plate 12 continues to rotate and disengages from the support frame 4, the free end of the elastic telescopic rod 3 moves downward to reset under its own elastic force. The downward movement of the free end of the elastic telescopic rod 3 drives the turntable 5 to move downward. The downward movement of the turntable 5 drives the workpiece 11 to move downward. The workpiece 11 moves back and forth while the shot blasting equipment is started to perform shot blasting operations.

[0027] Reference Figure 1-7Based on the above embodiments, another embodiment of the present invention further includes a separation component and a recovery component. The separation component is used to separate impurities and abrasives, and the recovery component is used to improve the recovery efficiency of impurities. The separation component includes a separation plate 131, a separation frame 132, a separation spring 133, a support frame 134, and a support ring 135. The separation plate 131 is slidably installed on the inner wall of the shot blasting frame 1, the separation frame 132 is fixedly installed on the inner wall of the shot blasting frame 1, the separation spring 133 is disposed between the separation plate 131 and the separation frame 132, and the separation plate 131 can be supported by the separation spring 133. The support frame 134 is fixedly installed on the top of the separation plate 131, and the support ring 135 is fixedly installed on the top of the support frame 134. The top of the separation plate 131 is provided with a separation hole. Efficient separation can reduce the situation where impurities are mistakenly screened out, thereby improving the abrasive recycling rate, reducing the frequency of abrasive replenishment, and indirectly reducing equipment maintenance costs.

[0028] The separation assembly also includes a rubber ring 136 and a rubber opening 137. The rubber ring 136 is disposed between the separation plate 131 and the separation frame 132. The rubber opening 137 is opened on the circumferential surface of the rubber ring 136. The load-bearing ring 135 is in contact with the elastic telescopic rod 3. The separation plate 131 is subjected to the reaction force of the rubber ring 136 and is buffered by the rubber ring 136. The elastic buffer of the rubber ring 136 can reduce the structural fatigue caused by high-frequency vibration and avoid bending or deformation problems after long-term use, thereby ensuring the flatness of the separation plate 131.

[0029] The top of the load-bearing frame 134 has a load-bearing hole, and the front side of the load-bearing frame 134 is set as an inclined surface. The front and rear sides of the separation frame 132 have connecting holes. When the separation plate 131 moves downward, it will squeeze the rubber ring 136, reducing the situation where qualified abrasive is mistakenly screened out along with impurities due to the deformation of the separation plate 131.

[0030] The recycling assembly includes a disintegration frame 141, a disintegration plate 142, a connecting plate 143, a disintegration spring 144, a shaking plate 145, and a shaking block 146. The disintegration frame 141 is slidably mounted on the circumferential surface of the elastic telescopic rod 3. The disintegration plate 142 is fixedly mounted on the bottom of the disintegration frame 141. The connecting plate 143 is fixedly mounted on the circumferential surface of the elastic telescopic rod 3. A disintegration spring 144 is provided between the connecting plate 143 and the disintegration plate 142, which can support the disintegration frame 141. The shaking plate 145 is fixedly mounted on the bottom of the separation frame 132. The shaking block 146 is fixedly mounted on the circumferential surface of the disintegration frame 141. The disintegration frame 141 rotates back and forth to break up the lumpy impurities that are stuck together with oil stains, which can prevent them from adhering to the inner wall of the shot blasting frame 1, reduce the incomplete cleaning caused by the adhesion of impurities, and thus improve the continuity of shot blasting operations.

[0031] The vibrating plate 145 is elastic, and the vibrating block 146 can be driven to vibrate by the elasticity of the vibrating plate 145. The disassembly frame 141 abuts against the separation plate 131, and the disassembly frame 141 contacts the vibrating plate 145. The rotation of the vibrating block 146 will knock on the vibrating plate 145.

[0032] During operation, the connecting plate 12 moves upward and disengages from the load-bearing ring 135. After the connecting plate 12 disengages from the load-bearing ring 135, the separating plate 131 moves upward under the elastic force of the separating spring 133. When the free end of the elastic telescopic rod 3 moves downward and resets under its own elastic force, it causes the connecting plate 12 to move downward. The connecting plate 12 moves downward and contacts the load-bearing ring 135, pressing it down. The load-bearing ring 135 moves downward under the pressure of the connecting plate 12, causing the load-bearing frame 134 to move downward. 4. Moving downwards causes the separating plate 131 to move downwards. The downward movement of the separating plate 131 compresses the separating spring 133. The separating spring 133 deforms and stores force due to the compression of the separating plate 131. At the same time, the up-and-down movement of the separating plate 131 shakes the abrasive and impurities on the top of the separating plate 131, thereby improving the separation effect of the abrasive and impurities. Meanwhile, the downward movement of the separating plate 131 compresses the rubber ring 136. The rubber ring 136 deforms due to the compression of the separating plate 131 and reacts back to the separating plate 131. The separating plate 131 is subjected to the reaction force of the rubber ring 136 and is buffered by the rubber ring 136.

[0033] When the separating plate 131 moves downward, it contacts and compresses the disassembly frame 141. The downward movement of the disassembly frame 141 causes the disassembly plate 142 to move downward, compressing the disassembly spring 144. The disassembly spring 144 deforms and stores force under the pressure of the disassembly plate 142. When the separating plate 131 moves upward under the elastic force of the separating spring 133, it disengages from the disassembly frame 141. After contact with the separating plate 131, the dispersing plate 142 moves upward under the elastic force of the dispersing spring 144. The upward movement of the dispersing plate 142 drives the dispersing frame 141 to move upward. The dispersing frame 141 moves back and forth and rotates to break up the falling impurities, thereby preventing oil stains and impurities from sticking together. At the same time, the rotation of the dispersing frame 141 will drive the shaking block 146 to rotate. The rotation of the shaking block 146 will knock on the shaking plate 145. The shaking block 146 will vibrate due to the reaction force of knocking on the shaking plate 145.

[0034] It should be noted that this application only illustrates the case of processing a single workpiece. Users can integrate multiple devices into one machine according to actual production needs to complete the processing of multiple workpieces at the same time and improve work efficiency.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
