[0002] The valve core of pilot solenoid valve is the key component in solenoid valve, and its movement state determines the opening and closing state of valve.In pilot solenoid valve, valve core is usually located at the center position of valve body, and is controlled to rise and fall by magnetic force generated by electromagnetic coil, when electromagnetic coil is energized, the magnetic field generated attracts valve core to rise, so that pilot hole is opened, thereby forming pressure difference around main valve core, and finally driving main valve core to move upward, to open main valve port;When electromagnetic coil is de-energized, magnetic field disappears, and under the action of spring force and gravity, valve core resets, pilot hole is closed, main valve core drops, and main valve port is closed, during the processing of pilot solenoid valve valve core, especially after casting, forging, machining and other steps, small protrusions or sharp parts, i.e.so-called burrs, are often formed on the surface, these burrs affect valve core assembly, and can cause scratches, blockage or performance degradation in valve body during use, therefore, deburring is a very important step in valve processing.

DETAILED DESCRIPTION

[0023] In order to have a clearer understanding of the technical features, objects and effects of the present application, the specific embodiments of the present application will be described with reference to the drawings.

[0024] Embodiment 1: The preferred embodiment of the surface deburring equipment for machining the valve core of the pilot electromagnetic valve provided by the present application is as shown in the figure. Figures 1 to 6 As shown: a surface deburring equipment for machining the valve core of the pilot electromagnetic valve, comprising a machining table 1;

[0025] The machining table 1 top surface is provided with a valve core body 2;

[0026] The valve core body 2 is externally provided with a control panel 3;

[0027] And a machining assembly 4 arranged outside the valve core body 2, the machining assembly 4 comprises a polishing assembly 41 arranged outside the valve core body 2, the polishing assembly 41 comprises a mounting plate 411 fixedly installed at the bottom of the machining table 1, a motor 412 fixedly installed at the bottom of the mounting plate 411, a rotating rod 413 fixedly installed at the output end of the motor 412, a gear column 414 fixedly installed at the end of the rotating rod 413, a first threaded rod 415 rotationally connected to the top surface of the machining table 1, a sleeve plate 416 sleeved on the outer wall of the first threaded rod 415, a limiting ring 417 fixedly installed on the outer wall of the sleeve plate 416, a sliding rod 418 arranged outside the limiting ring 417, a limiting ring 419 rotationally connected to the inner side of the limiting ring 417, a cylinder 420 fixedly installed at the end of the limiting ring 419, a gear ring 421 fixedly installed on the outer wall of the cylinder 420, a second threaded rod 422 sleeved in the cylinder 420, an arc plate 423 rotationally connected to the end of the second threaded rod 422, a deburring brush 424 fixedly installed on the side of the arc plate 423 away from the second threaded rod 422, and a limiting rod 425 fixedly installed on the side of the arc plate 423 away from the deburring brush 424.

[0028] When the valve core body 2 needs to be deburred in the embodiment, it is installed on the top surface of the machining table 1 through the adsorption assembly 43. At this time, the second threaded rod 422 is rotated. Since the outer wall of the limiting rod 425 is slidingly arranged inside the cylinder 420, and the end of the second threaded rod 422 is rotatably connected to the outer wall of the arc plate 423, under the limitation thereof, the rotating second threaded rod 422 can push the arc plate 423 connected to the end thereof, so that the arc plate 423 drives the deburring brush 424 to move, so that the deburring brush 424 is in contact with the outer wall of the valve core body 2. At this time, the motor 412 is started, and the rotating rod 413 fixedly installed at the output end thereof is rotated, and the gear column 414 fixedly installed at the end of the rotating rod 413 is rotated. Since the limiting ring 417 is rotatably connected to the inner side of the limiting ring 417 under the support of the first threaded rod 415 and the sliding rod 418, the limiting ring 417 can support the limiting ring 417 and the cylinder 420. Since the gear ring 421 fixedly installed on the outer wall of the cylinder 420 is engaged with the gear column 414, under the limitation thereof, the rotating gear column 414 drives the gear ring 421 to rotate, and the cylinder 420 fixedly installed on the inner side of the gear ring 421 rotates, and the second threaded rod 422 arranged inside the cylinder 420 drives the arc plate 423 and the deburring brush 424 to rotate, so that the deburring brush 424 rotates on the outer wall of the valve core body 2. The deburring brush 424 deburrs the outer wall of the valve core body 2. When different positions of the valve core body 2 need to be deburred, the first threaded rod 415 is rotated. Since the other set of plates 416 is slidingly arranged inside the outer wall of the limiting ring 417, under the limitation thereof, the rotating first threaded rod 415 can drive the sleeve plate 416 to move up and down, so that the sleeve plate 416 drives the limiting ring 417 to move. The limiting ring 417 is rotatably connected to the inner side of the limiting ring 417, and the cylinder 420 is moved as a whole. The cylinder 420, the second threaded rod 422, and the deburring brush 424 are adjusted and moved up and down to deburr different positions of the valve core body 2. The structure can adjust the position of the deburring brush 424 by rotating the second threaded rod 422 to polish the valve core body 2 of different sizes. When the first threaded rod 415 is rotated, the limiting ring 417 is moved, so that the limiting ring 417 drives the cylinder 420 to move up and down to deburr different parts of the valve core body 2. When the gear column 414 is rotated, the gear ring 421 is rotated, so that the deburring brush 424 is in contact with the outer wall of the valve core body 2 and is rotated to deburr, so that the burrs are taken out more uniformly.

[0029] Further, the gear column 414 is engaged with the gear ring 421, and the gear ring 421 is slidingly arranged on the outer wall of the gear column 414. Under the limitation thereof, the rotating gear column 414 can drive the gear ring 421 to rotate. When the first threaded rod 415 is rotated to adjust the position of the limiting ring 417, the limiting ring 417 drives the limiting ring 419, the cylinder 420, and the gear ring 421 to move up and down, so that the gear ring 421 slides on the outer wall of the gear column 414.

[0030] Furthermore, the limiting ring 419 fixedly installed at the end of the cylinder 420 is rotatably connected to the inner side of the limiting ring 417, and the toothed ring 421 is fixedly sleeved on the outer wall of the cylinder 420. Under its restriction, when the toothed ring 421 drives the cylinder 420 to rotate, the limiting ring 419 fixedly installed at the end of the cylinder 420 can rotate inside the limiting ring 417, so that the deburring brush 424 rotates and deburrs the outer wall of the valve core body 2.

[0031] Example 2: Based on Example 1, a preferred embodiment of the surface deburring equipment for processing the valve core of a pilot solenoid valve provided by this utility model is as follows: Figures 1 to 6 As shown: The adsorption assembly 43 includes a suction cup 431 fixedly installed on the top surface of the processing table 1. A suction tube 432 is connected inside the processing table 1. A sealing ring 433 is fixedly installed at the end of the suction tube 432. A retaining ring 434 is fixedly installed on the inner wall of the suction tube 432. A sealing ring 435 is slidably installed inside the suction tube 432. A pull rod 436 is fixedly installed on the side wall of the sealing ring 435. A telescopic rod 437 is fixedly installed at the end of the pull rod 436 away from the sealing ring 435. A bracket 438 is fixedly installed at the end of the telescopic rod 437 away from the pull rod 436.

[0032] In this embodiment, when deburring the valve core body 2 is required, its center is placed concentrically with the inner center of the cylinder 420, so that the bottom of the valve core body 2 contacts the suction cup 431. Under the suction of the suction cup 431, the suction cup 431 can be initially positioned. The bottom of the valve core body 2 contacts the top surface of the sealing ring 433. After the sealing ring 433 contacts the bottom of the valve core body 2, the inside of the sealing ring 433 is in a sealed state. At this time, the telescopic rod 437 is activated, which pulls the pull rod 436 and the sealing ring 435 towards the outer wall of the suction tube 432. Due to the sealing sliding between the outer wall of the sealing ring 435 and the inside of the suction tube 432, its... Under the constraint, the sealing ring 435 draws gas from the inside of the suction tube 432 and the sealing ring 433, causing the sealing ring 433 to be stably adsorbed onto the bottom of the valve core body 2, applying a downward pulling force to the bottom of the valve core body 2 to achieve the effect of fixing the valve core body 2. At this time, the valve core body 2 can be deburred by the grinding component 41. This structure can initially position the valve core body 2. Then, the telescopic rod 437 pulls the pull rod 436 and the sealing ring 435 to draw gas from the inside of the suction tube 432 and the sealing ring 433, applying a downward pulling force to the bottom of the valve core body 2 to quickly fix the valve core body 2.

[0033] Further, the outer wall of the sealing ring 435 is in sealing sliding contact with the inner portion of the suction pipe 432, the sealing ring 433 is of an adhesive material at the end away from the suction pipe 432, under the limitation of the sealing ring 433, the bottom of the valve core body 2 is in contact with the top surface of the sealing ring 433, so that the inner portion of the sealing ring 433 is in a closed state, under the limitation of the downward sliding of the sealing ring 435, the gas in the inner portion of the suction pipe 432 and the sealing ring 433 can be pumped out, so as to achieve the effect of fixing the valve core body 2.

[0034] In addition, the sealing ring 435 is arranged below the blocking ring 434, the pull rod 436 is arranged in sliding contact with the inner portion of the suction pipe 432, under the limitation of the blocking ring 434, the sealing ring 435 can be prevented from sliding out of the inner portion of the suction pipe 432 and the sealing ring 433.

[0035] The above is only a specific embodiment of the present application, and is not used to limit the scope of the present application. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present application shall fall within the scope of the present application. It should be noted that the components of the present application are not limited to the above overall application, and the technical features described in the specification of the present application can be selected for single use or combined use according to actual needs, therefore, the present application naturally covers other combinations and specific applications related to the present application.
