Description

Technical Field

[0001] The invention relates to the technical field of solenoid valve processing, and more specifically to an automatic combined processing device for a solenoid valve core. Background Art

[0002] As a key component in industrial automation control systems, solenoid valves are widely used in hydraulics, pneumatics, fluid control and other fields. The valve core is the core component of the solenoid valve, and its processing quality directly affects the sealing, response speed and service life of the solenoid valve.

[0003] In the process of processing the solenoid valve core, some processes still need to rely on non-automatic methods to complete. For example, the installation of the sealing ring on the straight-rod multi-way solenoid valve core (such as a four-way valve core, the more passages, the more sealing rings are needed) requires a combination of semi-automatic equipment and manual operation. In the manual installation stage, the operator needs to first put a metal tube with multiple sealing rings on the outside of the valve core, and then manually move the sealing rings one by one to the sealing groove position in the middle of the valve core; then, in the semi-automatic equipment processing, the operator needs to manually insert one end of the valve core into the installation hole of the equipment to complete the filling of the end sealing ring, and needs to change the direction of the valve core to repeat the operation. Although this combination of semi-automation and manual operation solves the problem of installing the sealing ring of the straight-rod multi-way solenoid valve core, both semi-automation and manual operation have shortcomings such as cumbersome procedures and large workload, and manual installation is also prone to the situation where the sealing ring is not accurately installed in the sealing groove, which seriously affects production efficiency.

[0013] Compared with the prior art, the advantages of the present invention are: 1. By utilizing the synergistic effect of the first electric push rod and the first motor, while the sealing ring is pushed through the push ring, the driving wheel can orderly push the sealing ring to the corresponding sealing groove on the valve core, and the outer surface of the sleeve is installed with a ball, which significantly reduces the friction between the sealing ring and the sleeve, so that the sealing ring can be easily, quickly and accurately installed in each sealing groove of the valve core. The entire installation process is simple, fast and fully automated, which not only greatly reduces labor costs and operating errors, but also reduces downtime and optimizes the production process, thereby effectively improving the production efficiency of the solenoid valve core processing, while ensuring the consistency and reliability of the product.

[0014] 2. Use appearance inspection equipment to identify whether the sealing ring in each sealing groove is installed in place. When the sealing ring deviates, stop the movement of the valve core immediately, and the second electric push rod and the drive wheel work together to drive the valve core to rotate. At the same time, through the cooperation of the rocker and the guide plate, the deviated sealing ring is accurately guided back to the sealing groove. The design of the guide plate not only reduces the difficulty of inserting the rocker between the sealing ring and the valve core, but also prevents the sealing ring from getting stuck through the cooperation of the slide plate and the first spring, ensuring a smooth and efficient reset process. In addition, the arc structure of the rocker and the ingenious design of the guide plate close to the outer edge of the sealing groove further improve the success rate of the sealing ring reset and avoid the dead angle problem. The entire device has a high degree of automation and can respond quickly and complete the reset when the sealing ring deviates, which significantly improves product quality and production efficiency, while reducing manual intervention and operating errors and reducing production costs.

[0015] 3. When the seesaw guides the sealing ring back to the sealing groove, the movement of the sealing ring drives the lever to move, thereby pushing the pressure rod to slide out of the semi-ring groove and compress the sealing ring. In addition, under the combined effect of the semi-ring groove limiting the movement of the sleeve ring and the pressure rod compressing the sealing ring, the sleeve ring can rotate synchronously with the valve core, so that the pressure rod plays the role of fixing the sealing ring at a fixed point, avoiding the sealing ring that has entered the sealing groove from being separated again when the seesaw pries the sealing ring at other positions, thereby ensuring that the sealing ring will not be separated from the sealing groove again after resetting. Based on the above advantages, not only the efficiency and reliability of the sealing ring resetting are significantly improved, but also the problem of the sealing ring being separated again is avoided, further ensuring the high efficiency of the solenoid valve core processing and the stability of product quality.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] For example, see Figures 1 to 12 As shown, the present invention discloses an automatic combined processing device for a solenoid valve core, comprising a sleeve 11, and a plurality of sealing rings 13 are sequentially installed on the outer side of the sleeve 11; A push ring 23 is sleeved at the beginning of the outer side of the sleeve 11, and one side of the push ring 23 contacts the sealing ring 13. A plurality of driving wheels 25 are symmetrically arranged at the end of the outer side of the sleeve 11, and each driving wheel 25 contacts the sealing ring 13 at the end of the sleeve 11. A valve core 31 is slidably connected inside the sleeve 11 , and a plurality of sealing grooves 32 are provided on the valve core 31 .

[0020] A plurality of balls 12 are equidistantly mounted on the outer side of the sleeve 11 , and each sealing ring 13 abuts against the plurality of balls 12 .

[0021] Two long rods 22 are symmetrically installed on the other side of the push ring 23. Each first electric push rod 21 is also installed near the starting end of the sleeve 11. The output end of each first electric push rod 21 is installed at the end of the corresponding long rod 22. A first motor 24 is provided on one side of each driving wheel 25, and the output end of the first motor 24 is installed on the side of the corresponding driving wheel 25.

[0022] In the assembly processing of the straight rod-shaped multi-way solenoid valve core, the traditional valve core sealing ring installation is to use mechanical equipment to install the sealing ring 13 in the sealing groove 32 at both ends of the valve core, or to manually install multiple sealing rings 13 into each sealing groove 32 on the valve core 31 one by one. The present invention first installs the sealing ring 13 to be installed on the outside of the sleeve 11 in sequence, and the external conveying device pushes the first electric push rod 21 from the beginning of the sleeve 11 and pushes it out from the end of the sleeve 11 in sequence. During this process, the first electric push rod 21 cooperates with the first motor 24, that is, the first electric push rod 21 extends, and the push ring 23 is pushed to slide outside the sleeve 11 through the long rod 22, and the push ring 23 pushes several sealing rings 13 to slide outside the sleeve 11. The push ring 23 is provided with a notch corresponding to the number and position of the several driving wheels 25, and the notch just avoids each driving wheel 25, which can prevent the push ring 23 from colliding with the driving wheel 25 when sliding to the end of the sleeve 11. Since the outer surface of the sleeve 11 is provided with a ball 12, when the sealing ring 13 slides on the surface of the sleeve 11, the friction between the sealing ring 13 and the sleeve 11 drives the ball 12 to roll, which can greatly reduce the friction between the sealing ring 13 and the sleeve 11, so that the push ring 23 can easily push a number of sealing rings 13 to move. The first electric push rod 21 drives the push ring 23 to move the sealing rings 13 through the long rod 22, forming an orderly feeding, and then the first motor 24 drives the driving wheel 25 to rotate, and the sealing ring 13 pushed by the push ring 23 can be just hit by the teeth on the driving wheel 25 (the last sealing ring 13 at the end of the sleeve 11), so that under the force of the driving wheel 25 continuing to rotate, it falls off from the tail end of the sleeve 11 and then enters the corresponding sealing groove 32 on the valve core 31. The first electric push rod 21 and the first motor 24 are both started at intervals, and the conveying device pushes the valve core 31 to slide inside the sleeve 11. When the sealing groove 32 of each section on the valve core 31 reaches the tail end of the sleeve 11, the first electric push rod 21 and the first motor 24 are started. The entire sealing ring installation process is simple and fast, and each sealing groove 32 can be efficiently installed, and the automation effect is achieved, which can reduce costs and effectively improve the production efficiency of the solenoid valve core processing.

[0023] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 12A second electric push rod 41 is installed near the end of the sleeve 11, and a truss 42 is installed at the output end of the second electric push rod 41. A shell 43 is symmetrically installed at both ends of the truss 42. A second motor 44 and a driving wheel 45 are installed on the shell 43. The output end of the second motor 44 is installed on one side of the driving wheel 45, and a propulsion wheel 46 is installed on the other side of the driving wheel 45. The propulsion wheel 46 is rotatably connected to the inside of the shell 43. A storage groove 47 is provided at the bottom end of the shell 43, and an embedded groove 48 is provided in the shell 43 on the side of the storage groove 47. One end of the storage groove 47 passes through the shell 43, and a turning slope 49 is fixed inside one end of the storage groove 47.

[0024] A telescopic column 51 is installed in the storage groove 47, and a plurality of propulsion teeth 52 are equidistantly installed on the surface of the telescopic column 51, and the propulsion wheel 46 is cooperated and connected with the propulsion teeth 52. A convex rod 53 is installed on the side of one end of the telescopic column 51, and the convex rod 53 is slidably connected in the embedded groove 48. A rocker 54 is installed at the other end of the telescopic column 51, and two sliding grooves 55 are penetrated on the rocker 54. A slide plate 56 is slidably connected in the slide groove 55. First springs 57 are symmetrically installed on both sides of the slide groove 55, and the slide plate 56 is elastically connected to the slide groove 55 through the first spring 57. A guide plate 58 is installed at the bottom of the rocker 54, and the bottom of the slide plate 56 penetrates the slide groove 55 and is installed on the top surface of the guide plate 58.

[0025] Although the sealing ring 13 can be automatically and efficiently installed in each sealing groove 32 in the first embodiment, the sealing ring 13 is made of rubber and has a certain elasticity. The sealing ring 13 may deviate under the action of its own elastic force, that is, part of the sealing ring 13 may be installed in the sealing groove 32, and the other part may be sleeved on the surface of the valve core 31, or the sealing ring 13 may be completely separated from the sealing groove 32 (as shown in the attached manual). Fig.12 In some cases shown in the figure), the sealing ring 13 needs to be reset in time to avoid unqualified products.

[0026] First, an appearance inspection device and a second electric push rod 41 are set near the tail end of the sleeve 11. The appearance inspection device is installed below the moving path of the valve core 31, and the second electric push rod 41 is installed above the moving path of the valve core 31, and the appearance inspection device and the second electric push rod 41 are on the same vertical line. When the valve core 31 passes, the appearance inspection device identifies and detects the sealing ring 13 on each sealing groove 32. When the position of the sealing ring 13 is found to be deviated, the conveying device, the first electric push rod 21 and the first motor 24 all stop running, and then the second electric push rod 41 starts (the initial state of the second electric push rod 41 is the extended state), driving the truss 42 to move, and the truss 42 drives the semi-ring shell 61 to approach the valve core 31, and finally the driving wheel 45 contacts the surface of the valve core 31, and the semi-ring shell 61 embraces the valve core 31 (the semi-ring shell 61 is designed as a semi-ring structure). Then, the second motor 44 is started, and the second motor 44 drives the driving wheel 45 to rotate. Since the driving wheel 45 contacts the surface of the valve core 31 , the driving wheel 45 can drive the valve core 31 to rotate synchronously.

[0027] In the initial state, the rocker plate 54 on the side of the housing 43 is located on both sides of the corresponding sealing groove 32 (i.e., the sealing groove 32 where the sealing ring 13 is offset) and is away from the sealing groove 32; the first spring 57 in the slide groove 55 pushes the slide plate 56 under the action of elastic force, so that it is located at one end of the slide groove 55 away from the telescopic column 51, that is, the slide plate 56 drives the guide plate 58 to slide out from the bottom of the rocker plate 54.

[0028] The driving wheel 45 drives the valve core 31 to rotate by friction, and also drives the propulsion wheel 46 inside the housing 43 to rotate. The propulsion wheel 46 cooperates with a plurality of propulsion teeth 52 on the telescopic column 51. When the propulsion wheel 46 rotates, the propulsion teeth 52 drive the telescopic column 51 to slide out of the storage groove 47, and the telescopic column 51 drives the seesaw 54 to approach the sealing groove 32, and drives the protruding rod 53 to slide in the embedded groove 48. When the sealing ring 13 deviates from the outside of the sealing groove 32, the seesaw 54 will be inserted between the surface of the valve core 31 and the sealing ring 13 when approaching the sealing groove 32, until the seesaw 54 hits the protrusions on both sides of the sealing groove 32. When the seesaw 54 approaches the sealing groove 32, the guide plate 58 protruding from the bottom of the seesaw 54 first approaches the sealing groove 32. Therefore, the guide plate 58 is first inserted between the surface of the valve core 31 and the sealing ring 13, thereby slightly lifting the sealing ring 13, making it easier for the seesaw 54 that arrives later to be inserted between the valve core 31 and the sealing ring 13, reducing the difficulty of inserting the seesaw 54 between the surface of the valve core 31 and the sealing ring 13, and improving the success rate. As the seesaw 54 continues to approach the sealing groove 32, the guide plate 58 is affected by the reaction force of the sealing ring 13 or blocked by the protrusion at the edge of the sealing groove 32, and will be retracted to the bottom of the seesaw 54 in the direction close to the telescopic column 51. During the retraction of the guide plate 58, the slide plate 56 is driven to slide to the other end of the slide groove 55 and compress the first spring 57. During the whole process, the slide plate 56 plays a role in blocking the sealing ring 13, preventing the sealing ring 13 from passing over the seesaw 54 when the seesaw 54 is inserted between the surface of the valve core 31 and the sealing ring 13.

[0029] When the seesaw 54 contacts the protrusions on both sides of the sealing groove 32, that is, the telescopic column 51 slides to the maximum distance in the receiving groove 47, at this time, the last propelling tooth 52 on the telescopic column 51 is between the spiral patterns of the propelling wheel 46, and will not be pushed by the continuously rotating propelling wheel 46, so the telescopic column 51 is stationary. When the telescopic column 51 drives the protruding rod 53 to reach the end of the receiving groove 47, the protruding rod 53 slides from the embedded groove 48 onto the turning slope 49, and is acted on by the turning slope 49 to rotate the telescopic column 51, thereby driving the seesaw 54 to deflect, that is, the tail end of the seesaw 54 tilts up to form an inclined surface. Since the seesaw 54 is designed as an arc structure, when one end of the seesaw 54 tilts up and the driving wheel 45 continuously drives the valve core 31 to rotate, the deviated sealing ring 13 will be guided by the seesaw 54 into the sealing groove 32, thereby achieving the reset effect.

[0030] Since the outer side of the protrusions on both sides of the sealing groove 32 is an inclined surface, when one end of the seesaw 54 is tilted, the guide plate 58 loses the obstruction of the two sides of the sealing groove 32, and slides out from the bottom of the seesaw 54 again under the elastic force of the first spring 57, and as the seesaw 54 is tilted, the ends of the guide plate 58 always contact the inclined surfaces on the outside of the two sides of the truss 42, thereby avoiding dead angles and preventing the sealing ring 13 from being stuck in the gap between the seesaw 54 and the outside of the sealing groove 32 during the process of being introduced into the sealing groove 32, thereby improving the success rate of the reset of the sealing ring 13. In addition, when the guide plate 58 slides out from the bottom of the seesaw 54, it drives the slide plate 56 to slide inside the slide groove 55, and the slide plate 56 can also play the role of pushing the sealing ring 13, which not only prevents the sealing ring 13 from being immobile, but also pushes the sealing ring 13 to accelerate the entry of the sealing ring 13 into the sealing groove 32.

[0031] Example 3: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 12 A semi-annular shell 61 is installed at the middle bottom of the truss 42, a semi-annular groove 62 is provided on the inner side of the semi-annular shell 61, a plurality of limiting female teeth 63 are provided on the inner wall of the semi-annular groove 62, a top rod 64 is installed on the inner wall of the lower end of the semi-annular groove 62, two push blocks 65 are staggeredly installed inside the upper end of the semi-annular shell 61, a lever 66 is fixed to the outer end of each push block 65, two second springs 67 are staggeredly installed inside the upper end of the semi-annular shell 61, each push block 65 and the lever 66 are elastically connected to the semi-annular shell 61 through the corresponding second spring 67.

[0032] A third spring 71 is installed inside the upper end of the semi-annular shell 61, and a ring 72 is slidably connected in the semi-annular groove 62. One end of the third spring 71 is installed on the side of the ring 72. Pulleys 73 are rotatably connected on both sides of the ring 72. The pulley 73 is slidably connected in the semi-annular groove 62. A pressure rod 74 is slidably connected in the ring 72. A fourth spring 75 is sleeved on the outer side of the pressure rod 74, and the pressure rod 74 is elastically connected to the ring 72 through the fourth spring 75. A limiting groove 76 is provided on the side of the pressure rod 74, and a wedge-shaped platform 77 is installed on the top of the pressure rod 74. A limiting sub-tooth 78 is fixed on the top surface of the wedge-shaped platform 77, and the limiting sub-tooth 78 is meshed and connected with the limiting mother tooth 63.

[0033] A rotating shaft 81 is rotatably connected inside the side of the ring 72, and a control plate 83 is installed on the rotating shaft 81. Torsion springs 82 are installed on the rotating shaft 81 on both sides of the control plate 83, and the control plate 83 is elastically connected to the ring 72 through the torsion springs 82. A limit block 84 and a fifth spring 85 are installed inside the ring 72, and the limit block 84 is elastically connected to the inside of the ring 72 through the fifth spring 85, and one end of the control plate 83 abuts against the end of the limit block 84.

[0034] In order to ensure that the sealing ring 13 can be efficiently reset, a semi-ring shell 61 is also provided in the middle of the truss 42. When the seesaw 54 guides the sealing ring 13 into the sealing groove 32, the sealing ring 13 under the truss 42 has a convex movement and a transverse movement toward the sealing groove 32. The movement of the sealing ring 13 can drive the lever 66 on the corresponding side to move (see the attached manual). Fig.12 It can be seen that the offset position of the sealing ring 13 will be on the side where the sealing groove 32 does not have the sealing ring 13. In all embodiments, the movement of the seesaw 54 on the side where the sealing groove 32 does not have the sealing ring 13 is meaningless, and the corresponding lever 66 will not move). The lever 66 drives the push block 65 to squeeze the wedge-shaped platform 77 and compresses the second spring 67 at the same time. The wedge-shaped platform 77 is squeezed and moves downward, driving the limiting sub-tooth 78 on its top surface to separate from the limiting mother tooth 63. The wedge-shaped platform 77 drives the pressure rod 74 to slide toward the collar 72, slide out from the semi-ring groove 62, and abut against the surface of the sealing ring 13 entering the inside of the sealing groove 32. When the wedge-shaped platform 77 drives the pressure rod 74 to slide toward the collar 72, it also compresses the fourth spring 75, and makes the limiting groove 76 on the surface of the pressure rod 74 slide into the collar 72, and engages with the fifth spring 85 provided inside the collar 72, so as to limit the movement of the pressure rod 74, so that it keeps sliding out from the semi-ring groove 62 and tightly abutting against the sealing ring 13. Since the limiting sub-teeth 78 are separated from the limiting mother teeth 63, and the pressure rod 74 is pressed against the sealing ring 13, the valve core 31 and the sealing ring 13 will drive the collar 72 to slide in the semi-annular groove 62 through the pressure rod 74 during the synchronous rotation. During the sliding of the collar 72 in the semi-annular groove 62, the pressure rod 74 plays a role in fixing the sealing ring 13 at a fixed point, thereby preventing the sealing ring 13 that has entered the sealing groove 32 from being separated again when the subsequent seesaw 54 pries the sealing ring 13 at other positions, thereby ensuring that the sealing ring 13 can return to the sealing groove 32 efficiently and reliably. When the collar 72 slides in the semi-annular groove 62, the pulleys 73 at both ends of the collar 72 roll in the semi-annular groove 62, which can greatly reduce the friction resistance between the collar 72 and the semi-annular groove 62. Even when the pressure rod 74 is tightly against the sealing ring 13, the collar 72 can still stably follow the sealing ring 13 in a circular motion.

[0035] During the sliding process of the collar 72 in the semi-ring groove 62, the third spring 71 is stretched. When the collar 72 slides to the tail end of the semi-ring groove 62, that is, after the collar 72 follows the sealing ring 13 or the valve core 31 to rotate half a circle, one end of the control plate 83 on the side of the collar 72 contacts the push rod 64 on the side of the tail end of the semi-ring groove 62, and the push rod 64 pushes the control plate 83 to swing, and the control plate 83 drives the rotating shaft 81 to rotate, and the torsion spring 82 accumulates force, and the other end of the control plate 83 swings to the outside of the collar 72, releasing the limit block 84, and the limit block 84 slides into the inside of the collar 72 under the push of the fifth spring 85, thereby separating from the limit groove 76, and then releasing the restriction on the pressure rod 74, and then under the elastic force of the fourth spring 75, the pressure rod 74 and the wedge-shaped platform 77 rise (see the attached manual). Fig.11 The limiting sub-tooth 78 is meshed with the limiting female tooth 63 again, and the pressure rod 74 no longer contacts the sealing ring 13 after rising, and when moving from the end of the semi-annular groove 62 to the head end, the limiting female tooth 63 cannot limit the sliding of the limiting sub-tooth 78. Therefore, the ring 72 without resistance drives the pressure rod 74 and the wedge-shaped platform 77 to return to the head end of the semi-annular groove 62 under the elastic force of the third spring 71.
