Description

Technical Field

[0001] This invention belongs to the field of mechanical processing technology, specifically relating to an automatic air blowing device for drilling the piston of the main valve of a shock absorber solenoid valve. Background Technology

[0002] The automatic air blowing equipment for drilling the main valve piston of the shock absorber solenoid valve is a specialized device integrating mechanical structure design, automated control, and pneumatic technology. During the drilling process of the main valve piston of the shock absorber solenoid valve, it automatically triggers a high-pressure airflow through a preset program to remove metal debris, coolant residue, and dust generated during drilling in real time. This ensures processing accuracy and surface quality while preventing equipment jamming or processing errors caused by debris accumulation. The automated air blowing technology improves processing efficiency and product quality while reducing labor intensity and production costs, aligning with the trend of manufacturing transformation towards intelligence and precision. It possesses significant technological innovation and promising market application prospects.

[0003] Before the main valve piston removes metal debris, coolant residue, and dust generated during drilling through high-pressure airflow, it needs to be installed sequentially in the workpiece positioning fixture. In the automated air blowing production line for automotive pistons, traditional equipment uses manual or simple robotic arms to grip the workpiece positioning fixture and transfer it from the preparation area to the processing position. Due to the lack of precise guidance in the gripping action, the fixture is prone to slight displacement during the transfer process, resulting in misalignment between the piston hole position and the air hole axis of the bottom hole positioning block and the main hole positioning block. If the axis is misaligned, the airflow will generate eddies or reflections in the hole, which cannot effectively blow away metal debris, coolant residue, and dust from the bottom and side walls of the hole.

[0004] Therefore, the present invention provides an automatic air blowing device for drilling holes in the main valve piston of a shock absorber solenoid valve. Summary of the Invention

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 4 As shown, the present invention provides a technical solution: an automatic air blowing device for drilling the piston of the main valve of a shock absorber solenoid valve, comprising an electrical cabinet 1, a reciprocating cylinder 4 and a reciprocating cylinder 5 fixedly connected to the top of the electrical cabinet 1, a bottom hole positioning block 2 fixedly connected to the output end of the reciprocating cylinder 4, and a main hole positioning block 3 fixedly connected to the output end of the reciprocating cylinder 5, with multiple air holes provided on the adjacent side of the bottom hole positioning block 2 and the main hole positioning block 3, a pneumatic control valve 7 fixedly installed on the side wall of the electrical cabinet 1, with multiple air pipes 6 fixedly connected to the outer end of the pneumatic control valve 7, and the air pipes 6 fixedly connected to the air holes provided on the bottom hole positioning block 2 and the main hole positioning block 3, respectively, and a positioning sliding assembly provided between the bottom hole positioning block 2 and the main hole positioning block 3, the positioning sliding assembly including a workpiece positioning fixture 13, the workpiece positioning fixture 13 being movable along the bottom hole positioning block 2 and the main hole positioning block 3.

[0023] During operation: Before using the device, the main valve piston workpiece is sequentially installed in the inner hole of the workpiece positioning fixture 13. Then, the workpiece positioning fixture 13 is engaged in the set position of the positioning sliding assembly. The positioning sliding assembly is then activated, and the workpiece positioning fixture 13 moves along a preset path. The piston workpiece installed in the inner hole of the workpiece positioning fixture 13 will pass between the bottom hole positioning block 2 and the main hole positioning block 3. Then, the reciprocating cylinder 4 and the reciprocating cylinder 5 extend synchronously, driving the bottom hole positioning block 2 and the main hole positioning block 3 to move towards each other until the air hole is aligned with the main hole positioning block 3. The bottom hole and main hole of the piston workpiece are aligned. The pneumatic control valve 7 receives the PLC command and opens the corresponding air path according to the preset pressure parameters. High-pressure gas is delivered to the positioning block air holes at the bottom hole positioning block 2 and the main hole positioning block 3 through the air pipe 6. The system activates the solenoid coil of the pneumatic control valve one by one according to the hole processing sequence. The high-pressure airflow is sprayed in the form of short pulses. The pneumatic impact force is used to peel off the aluminum chips, coolant and other debris attached to the hole wall. After the blowing is completed, the pneumatic control valve 7 closes the air path, and the cleaned workpiece positioning fixture 13 is taken out and enters the next production cycle.

[0024] like Figures 5 to 11 As shown, the positioning sliding assembly includes a slide rail 8, with two slide rail blocks 9 slidably connected to the outer wall of the slide rail 8. A rack 12 is fixedly connected to one side of each slide rail block 9. A servo motor 10 is fixedly installed on the top of the electrical cabinet 1. A gear 11 is fixedly connected to the output shaft of the servo motor 10. The teeth of the gear 11 can mesh with the teeth of the rack 12. A material preparation assembly is provided on the top of the electrical cabinet 1. The material preparation assembly includes a placement platform 17, which is used to place and position the workpiece positioning fixture 13 to be processed. A material picking assembly and a material fixing assembly are provided above the slide rail blocks 9. The material picking assembly includes two vertically lifting clamping plates 14, which are located above the slide rail blocks 9. The material fixing assembly enhances the stability of the workpiece positioning fixture 13 after clamping it.

[0025] During operation: The slide rail block 9 is pre-positioned at the end of the slide rail 8, directly below the placement platform 17 of the material preparation assembly. At this time, the workpiece positioning fixture 13 carrying the piston workpiece is placed on the placement platform 17 and enters the standby state. The remaining components of the material preparation assembly position the workpiece positioning fixture 13 at a precise preset position. When it is necessary to clamp the workpiece positioning fixture 13, the material picking assembly is activated, and the two vertically lifting clamping plates 14 rise synchronously. Their inner grooves slide along the sides of the fixture, gradually covering the two sides of the workpiece positioning fixture 13, so that the two sides of the workpiece positioning fixture 13 gradually enter the inner grooves of the two clamping plates 14 respectively. When the workpiece positioning fixture 13 moves upward and the sides are completely inserted into the inner grooves of the clamping plates 14, the material fixing assembly plays its role, tightly locking the current state of the workpiece positioning fixture 13 and the clamping plates 14, forcibly fixing the relative position of the workpiece positioning fixture 13 and the clamping plates 14. This prevents the clamping plate 14 from slipping off the workpiece positioning fixture 13 when it descends and resets, avoiding misalignment of the piston hole with the air holes of the bottom hole positioning block 2 and the main hole positioning block 3 during subsequent processing due to positioning deviation. In addition, the material fixing assembly also ensures that the slide block 9 does not loosen or wobble when moving along the outer wall of the slide rail 8. After clamping the workpiece positioning fixture 13 into the inner groove of the two clamping plates 14, the servo motor 10 is started. Its output shaft drives the rack 12 through the gear 11, causing the slide block 9 to slide along the outer wall of the slide rail 8. With the precise guidance of the slide rail 8 on the slide block 9, the workpiece positioning fixture 13 will move between the bottom hole positioning block 2 and the main hole positioning block 3, thereby gradually completing the entire air blowing processing operation. After the fixture moves to the predetermined position, high pressure is injected directionally through the pre-set air holes to remove debris from the holes. After processing is completed, the fixture is moved to the unloading position to enter the next cycle. Through the above embodiments, the material preparation component provides a pre-stored station for the workpiece positioning fixture 13 carrying the piston workpiece, and accurately fixes the fixture in the preset position to ensure the consistency of the initial state, realize the rapid positioning and standby of the fixture, and provide a benchmark guarantee for subsequent automated material handling; the material preparation component, together with the material handling component, through synchronous upward movement, makes the inner groove of the clamping plate 14 slide along the side of the workpiece positioning fixture 13 and cover the two side edges to complete the clamping and initial fixing of the fixture; through the material fixing component, after the clamping plate 14 completes the clamping of the fixture, it forcibly locks the relative position of the workpiece positioning fixture 13 and the clamping plate 14, and suppresses the shaking of the fixture during the transfer of the slide rail block 9, ensuring that the fixture does not fall off when the clamping plate 14 is reset, and preventing the piston hole position from being misaligned with the air hole of the bottom hole positioning block 2 and the main hole positioning block 3 due to positioning deviation. Through rigid locking or dynamic clamping, the risk of fixture loosening when the slide rail moves 8 is eliminated, ensuring the stability of the air blowing process.

[0026] like Figures 5 to 7As shown, the material preparation assembly also includes a receiving plate seat 22, which is fixedly connected to the top of the electrical cabinet 1. An H-shaped connecting frame is fixedly connected above the receiving plate seat 22. A positioning plate 24 is symmetrically fixedly connected above the H-shaped connecting frame. A positioning block 25 is fixedly connected to one side of the H-shaped connecting frame. Protective plates 26 are symmetrically arranged above the receiving plate seat 22. The inner sides of the two protective plates 26 are respectively attached to the two side walls of the workpiece positioning fixture 13.

[0027] During operation: When the workpiece positioning fixture 13 is placed above the placement table 17, the H-shaped connecting frame above the receiving plate seat 22 forms a lateral limit on the top of the placement table 17 through the two side clamping plates 24, preventing the placement table 17 from overturning or shifting due to external forces; when the clamping plate 14 moves upward, the clamping plate 24 further forms a vertical constraint on the top of the workpiece positioning fixture 13, preventing the fixture from shifting laterally due to the frictional resistance when contacting the inner groove of the clamping plate 14, ensuring that the side of the fixture can be smoothly embedded into the inner groove of the clamping plate 14; at this time, the positioning block 25 on one side of the H-shaped connecting frame precisely fits against the back of the fixture. The clamping plate 14 provides a longitudinal reference for aligning the inner groove with the side of the fixture, ensuring that the two remain coaxial during the upward movement and preventing clamping failure due to misalignment. The two protective plates 26 accurately position the side of the workpiece positioning fixture 13, preventing lateral offset or vibration of the workpiece positioning fixture 13 when it first enters the inner groove of the clamping plate 14 due to the impact force at the moment of contact or the slight dimensional deviation between the inner groove and the side. This would cause the side to scrape or get stuck with the edge of the inner groove, or even cause the fixture to deviate from the preset clamping trajectory. In addition, a feeding device can be set on the other side of the placement table 17. Whenever a workpiece positioning fixture 13 is clamped, the next workpiece to be processed can be added to the top of the placement table 17 in a timely manner. The feeding device is existing technology and will not be described in detail.

[0028] like Figure 11 As shown, a bearing seat 27 is fixedly connected above the receiving plate seat 22, and both ends of the shaft of the bearing seat 27 are fixedly connected to one end of the protective plate 26.

[0029] During operation: When the clamping plate 14 moves upward, its inner wall first contacts the side edge of the workpiece positioning fixture 13 and completes the initial clamping and positioning; as the clamping plate 14 continues to rise, its top gradually presses against the bottom of the protective plate 26, forcing the protective plate 26 to rotate outward with the shaft of the bearing seat 27 as the rotation center; at this time, the protective plate 26 automatically releases the physical limit on the side of the fixture, allowing the clamping plate 14 to completely take over the positioning function, and achieve stable clamping through the deep engagement of the inner groove with the side of the fixture; thus, it not only ensures accurate positioning in the initial stage, but also avoids motion interference between the protective plate 26 and the clamping plate 14, ensuring that the entire clamping process is smooth and efficient.

[0030] like Figure 9 and Figure 11 As shown, an outer plate 28 is symmetrically fixedly connected to the outer wall of the shaft of the bearing housing 27. A torsion spring 29 is fixedly connected to one side of the outer plate 28. A fixed platform 30 is fixedly connected to one side of the bearing housing 27. The end of the torsion spring 29 away from the outer plate 28 is fixedly connected to the top of the fixed platform 30.

[0031] During operation: When the inner groove of the clamping plate 14 is embedded into the side edge of the workpiece positioning fixture 13 and continues to move upward, causing the protective plate 26 to rotate, the protective plate 26 will drive the shaft of the bearing seat 27 to rotate. The outer plate 28 will rotate together with the shaft of the bearing seat 27 and compress the torsion spring 29 to deform. After the clamping plate 14 completes the clamping action and clamps the workpiece positioning fixture 13 and descends to reset, the torsion spring 29 releases the stored elastic force to drive the outer plate 28 to rotate in the opposite direction, thereby driving the protective plate 26 to automatically return to the initial limit state, restoring the side restriction function of the workpiece positioning fixture 13, and providing a reliable guarantee for the continuous positioning of the subsequent fixture.

[0032] like Figures 6 to 8 As shown, the material handling assembly also includes two telescopic rods 16, which are fixedly connected to the top of the slide rail block 9. The top of each telescopic rod 16 is fixedly connected to a side receiving platform 15, which is fixedly connected to one side of the clamping plate 14.

[0033] During operation: When the clamping plate 14 needs to clamp the workpiece positioning fixture 13, the telescopic rod 16 activates its telescopic function, and its top end pushes the clamping plate 14 vertically upward through the side mounting platform 15. During the upward movement, the inner groove of the clamping plate 14 first embeds into the side edge of the workpiece positioning fixture 13 to complete the initial positioning, and then continues to rise to press the bottom of the protective plate 26, triggering the protective plate 26 to rotate outward around the shaft of the bearing seat 27. At this time, the telescopic rod 16 continues to extend to ensure that the clamping plate 14 completely takes over the clamping function of the side of the fixture. After the material is picked up, the telescopic rod 16 retracts to drive the clamping plate 14 to descend vertically and reset. During the descent, the workpiece positioning fixture 13 is relatively fixed to the position of the clamping plate 14 through the fixing component, so that the workpiece positioning fixture 13 and the clamping plate 14 descend together without slippage.

[0034] like Figures 6 to 8 As shown, the solidification assembly includes two lateral displacement blocks 19, which are slidably connected to the surface of the side receiving platform 15. A limit block 18 is fixedly connected to the top of the side receiving platform 15. A lateral displacement component is provided on one side of the lateral displacement block 19, which can drive the lateral displacement block 19 to slide laterally along the surface of the side receiving platform 15.

[0035] During operation: When the clamping plate 14 rises under the drive of the telescopic rod 16, the side platform 15 simultaneously drives the limiting top block 18 to move upward. At the same time, the side shifting component is activated, driving the side shifting block 19 to slide along the surface of the side platform 15 to both sides, so that the limiting top block 18 moves horizontally to a safe distance. This ensures that the limiting top block 18 will not interfere with the side of the workpiece positioning fixture 13 during the rising process, providing unobstructed space for the precise embedding of the inner groove of the clamping plate 14 and the side of the fixture. After the clamping plate 14 has completely clamped the side of the fixture, the side shifting component drives the side shifting block 19 to slide inward in the opposite direction, driving the limiting top block 18 to return to a horizontal position directly above the fixture. At this time, the bottom end of the limiting top block 18 is tightly attached to the top surface of the fixture, forming a vertical constraint. This ensures that after the two clamping plates 14 have completely clamped the workpiece positioning fixture 13, the clamping plates 14 and the workpiece positioning fixture 13 maintain a fixed relative position, and there will be no slippage or shaking during subsequent movements.

[0036] like Figures 7 to 9 As shown, the lateral shifting assembly includes two extrusion blocks 20, which are fixedly connected to one side of the lateral shifting block 19. Each extrusion block 20 has an extrusion column 21 on its upper side. The bottom surface of the extrusion column 21 is inclined. A return spring 31 is fixedly connected to the other side of the lateral shifting block 19. A driving assembly is provided on one side of the extrusion column 21, which can drive the extrusion column 21 to move laterally.

[0037] During operation: When the clamping plate 14 rises under the drive of the telescopic rod 16, the pressing block 20 fixed to one side of the side-moving block 19 moves upward synchronously. At this time, under the initial positioning of the driving assembly, the bottom inclined surface of the pressing column 21 contacts the inclined surface of the pressing block 20. As the pressing block 20 continues to rise, the two inclined surfaces slide relative to each other, converting the vertical displacement into a horizontal thrust, forcing the side-moving block 19 to slide along the surface of the side-mounted platform 15 away from the workpiece positioning fixture 13. During this process, the return spring 31 is stretched and stores energy, and at the same time, the limiting top block 18 moves synchronously with the side-moving block 19. Lateral shift creates a safe misalignment space with the side of the fixture. After the inner groove of the clamping plate 14 is fully engaged with the side of the fixture, the drive assembly starts and moves the extrusion column 21 laterally, causing its straight wall to disengage from the extrusion block 20. At this time, the lateral shift block 19 loses its horizontal constraint, the reset spring 31 releases its elastic potential energy, and drives the lateral shift block 19 to slide in the opposite direction along the side platform 15, causing the limiting top block 18 to accurately reset to directly above the fixture. Finally, the bottom end of the limiting top block 18 is tightly attached to the top surface of the fixture, forming a vertical and horizontal bidirectional constraint with the lateral clamping force of the clamping plate 14, thus completing the stable locking of the workpiece.

[0038] like Figures 9 to 10As shown, the drive assembly includes a telescopic rod 23, which is fixedly connected to the inner wall of the receiving plate seat 22. The output end of the telescopic rod 23 is fixedly connected to one side of the placement platform 17. The outer wall of the placement platform 17 is slidably connected to the inner wall of the receiving plate seat 22. Two extrusion columns 21 are fixedly connected to the side of the placement platform 17 respectively.

[0039] During operation: When the clamping plate 14 rises to completely cover the side of the workpiece positioning fixture 13, the telescopic rod 23 starts and retracts, driving the placement table 17 to slide horizontally along the inner wall of the retracting plate seat 22 and retract. At this time, the placement table 17 disengages from the support surface of the bottom of the workpiece positioning fixture 13, so that the fixture is completely held by the clamping plate 14, so that when the clamping plate 14 descends, it can drive the workpiece positioning fixture 13 to move down together to complete the material picking step. During the retraction of the placement table 17, the two extrusion columns 21 fixed on its side move horizontally synchronously. When the straight wall of the extrusion column 21 completely disengages from the contact with the extrusion block 20, the side-moving block 19 loses the horizontal constraint force. At this time, the reset spring 31 releases the elastic potential energy, driving the side-moving block 19 to slide in the opposite direction along the surface of the side connecting platform 15, driving the limiting top block 18 to accurately reset to the top of the fixture. Finally, the bottom end of the limiting top block 18 is tightly attached to the top surface of the fixture, forming a vertical constraint.

[0040] like Figures 1 to 2 As shown, a pressure gauge 32 is fixedly installed on the top of the electrical cabinet 1. The surface of the pressure gauge 32 is equipped with a touch screen 33, an emergency stop button 34, a start button 35, a stop button 36, and a status indicator light 37.

[0041] During operation: The barometer 32 serves as the monitoring and control center of the air pressure system, displaying the system air pressure value in real time, and providing a parameter setting interface through the touch screen 33. The emergency stop button 34, start button 35, stop button 36 and status indicator light 37 serve as the control center to ensure the stable operation of the equipment.
