Description

Technical Field

[0002] The solenoid valve yoke assembly inner core processing equipment is an automated mechanical device dedicated to the precision processing of the inner core of the solenoid valve yoke assembly. Its core function is to realize the integrated operation of clamping, rotating, positioning and processing of the yoke inner core through the combination of mechanical structure and automatic control technology to meet the solenoid valve's demand for high-precision and high-stability magnetic circuit components.

[0003] Traditional fixtures for machining thinner inner cores of tubular solenoid valve yoke assemblies (such as three-jaw chucks) are prone to cause local stress concentration, exacerbating the deformation of thin-walled parts. When machining thinner inner cores of tubular solenoid valve yoke assemblies, the thinner tubular inner core is prone to elastic or plastic deformation due to clamping force, cutting force or residual stress during machining, resulting in unqualified products. Soft magnetic alloy materials have strong adhesion and poor thermal conductivity, and are prone to built-up edge during turning, exacerbating tool wear, resulting in substandard surface roughness, and even a "snowflake-like" surface, affecting the sealing and performance of the solenoid valve. The heat generated during machining may cause thin-walled parts to thermally expand, shrink and deform after cooling, further exacerbating dimensional deviations. Summary of the Invention

The surface of the movable block 308 is provided with a rubber layer, and the rubber layer provided on the surface of the movable block 308 can play a buffering and anti-slip role, and can also make the movable block 308 better adapt to fit different sizes. The inner core of the solenoid valve yoke assembly, the inward movement of the movable block 308 will drive the clamping block 309 to move inward, and the inward movement of the clamping block 309 will contact the tubular inner core of the solenoid valve yoke assembly and slide into the first sleeve 307; the structure is set, when the servo motor 301 rotates, it will drive the four sliding rods 306 to slide into the first sleeve 307, and the sliding rods 306 slide into the first sleeve 307 and drive the four clamping blocks 309 to clamp the thinner tubular inner core of the solenoid valve yoke assembly.

The inward sliding of the connecting rod 501 will drive the rubber block 503 to slide inward. The inward sliding of the rubber block 503 will compress the compression spring 504. At this time, the water inside the third hollow groove 5021 will pass through the connecting pipe 505 and enter the first nozzle 601. With the set structure, when the clamping block 309 moves inward, it will drive the rubber block 503 away from the third hollow groove 5021. At this time, the water inside the third hollow groove 5021 will pass through the connecting pipe 505 and enter the first nozzle 601.

The fan-shaped coolant sprayed from the several small holes can clean the inner surface of the first sleeve 307. The water inside the fixed block 603 enters the interior of the second nozzle 604. The water sprayed from the interior of the second nozzle 604 will cool the inner core of the tubular solenoid valve yoke assembly.

[0041] Working principle: Working principle: When the present invention is in use, the inner core of the relatively thin tubular solenoid valve yoke assembly is first placed in the first sleeve 307, and cooling water is introduced into the first bellows 201. The cooling water passes through the first bellows 201 and enters the sliding rod 306. The water inside the sliding rod 306 enters the third hollow groove 5021 through the hose inside the movable block 308. The servo motor 301 is started to rotate. The rotation of the servo motor 301 will drive the worm 302 to rotate. The rotation of the worm 302 will drive the worm gear 303 to rotate. The rotation of the worm gear 303 will drive the rotating pin 305 to move inward through the guide groove 304. The inward movement of the rotating pin 305 will drive the sliding rod 306 to move inward. The inward movement of the sliding rod 306 will drive the movable block 308 to move inward. The movable block 308 A rubber layer is provided on the surface. The rubber layer provided on the surface of the movable block 308 can play a buffering and anti-slip role. At the same time, it can also make the movable block 308 better adapt to fit the inner cores of the solenoid valve yoke assemblies of different sizes. The inward movement of the movable block 308 will drive the clamping block 309 to move inward. The clamping block 309 moves inward and contacts the tubular inner core of the solenoid valve yoke assembly and slides into the first sleeve 307. With the structure set up, when the servo motor 301 rotates, it drives the four sliding rods 306 to slide into the first sleeve 307. The sliding rods 306 slide into the first sleeve 307 and drive the four clamping blocks 309 to clamp the thinner tubular inner core of the solenoid valve yoke assembly. Multiple clamping blocks 309 are equidistantly arranged on the inner surface of the movable block 308 to play an anti-slip role.

[0042] When the clamping block 309 slides into the first sleeve 307, the piston 402 will be driven to compress the air inside the second hollow groove 3092, and a negative pressure will be formed inside the second hollow groove 3092. The negative pressure will further fix the thinner tubular solenoid valve yoke assembly inner core through the vacuum adsorption channel 3091. Combined with the clamping block 309, the thinner tubular solenoid valve yoke assembly inner core can be better clamped. After the thinner tubular solenoid valve yoke assembly inner core is clamped, the controller controls the mechanical arm 103 to drive the drill bit 105 to adjust the angle, and the hydraulic cylinder 104 is used to drive the drill bit 105 to drill downwards. The structure is arranged such that when the four clamping blocks 309 clamp the thinner tubular inner core of the solenoid valve yoke assembly, the clamping block 309 will slide into the movable block 308. The sliding of the clamping block 309 into the movable block 308 will compress the compression spring 504. When the clamping block 309 slides into the movable block 308, it will drive the piston 402 to vacuum the vacuum adsorption channel 3091. The vacuum adsorption channel 3091 forms a negative pressure, which will further fix the thinner tubular inner core of the solenoid valve yoke assembly. The flexible clamp and vacuum adsorption are used to fix the thinner tubular inner core of the solenoid valve yoke assembly to reduce clamping deformation.

[0043] When the clamping block 309 moves inward, it will drive the connecting rod 501 to slide into the second sleeve 502. The inward sliding of the connecting rod 501 will drive the rubber block 503 to slide inward. The inward sliding of the rubber block 503 will compress the compression spring 504. At this time, the water inside the third hollow groove 5021 will enter the first nozzle 601 through the connecting pipe 505. With the set structure, when the clamping block 309 moves inward, it will drive the rubber block 503 away from the third hollow groove 5021. At this time, the water inside the third hollow groove 5021 will enter the first nozzle 601 through the connecting pipe 505.

[0044] The water inside the first nozzle 601 will cool the inner core of the tubular solenoid valve yoke assembly, and at the same time, the water inside the first nozzle 601 will clean the debris generated by the machining of the inner core of the tubular solenoid valve yoke assembly. The first nozzle 601 is provided with small holes on the side and the lower end. The coolant sprayed by the first nozzle 601 can not only cool and clean the workpiece evenly, but also clean the inner surface of the movable block 308. The cleaned coolant and debris will fall from the lower end through the first sleeve 307 into the receiving bucket 101 for collection. The receiving bucket 101 is meshed, so the receiving bucket 101 can collect the metal debris generated by the machining. The water inside the first nozzle 601 will also pass through the second bellows. 602 enters the interior of the fixed block 603. Several small holes are provided at the lower end of the fixed block 603. The fan-shaped coolant sprayed from the several small holes can clean the inner surface of the first sleeve 307. The water inside the fixed block 603 enters the interior of the second nozzle 604. The water sprayed from the interior of the second nozzle 604 will cool the inner core of the tubular solenoid valve yoke assembly. Through the set structure, the water inside the first nozzle 601 will cool the inner core of the tubular solenoid valve yoke assembly, and at the same time, the debris generated by the processing of the inner core of the tubular solenoid valve yoke assembly can be washed in time to avoid the debris generated by the processing from adhering to the surface of the first sleeve 307 and the movable block 308, thereby affecting heat dissipation and subsequent processing.
