Description

Technical Field

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

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

[0003] During the processing of solenoid valve spools, some processes still need to be completed in a non-automatic manner. For example, the installation of seals on a straight rod-shaped multi-way solenoid valve spool (such as a four-way spool, the more passages there are, the more seals are required) requires a combination of semi-automatic equipment and manual operation. In the manual installation stage, the operator first needs to put a metal tube with multiple seals on the outside of the spool, and then manually move each seal to the sealing groove position in the middle of the spool one by one; subsequently, in the semi-automatic equipment processing, the operator needs to manually insert one end of the spool into the installation hole of the equipment to complete the filling of the end seal, and needs to change the orientation of the spool and repeat the operation. Although this semi-automatic and manual combination method solves the problem of seal installation on the straight rod-shaped multi-way solenoid valve spool, both semi-automatic and manual operations have deficiencies such as cumbersome processes and large workloads, and manual installation is also prone to the situation where the seal is not accurately installed in the sealing groove, thus seriously affecting production efficiency. Therefore, it is necessary to propose an automatic combined processing device for a solenoid valve spool to solve the above problems. Summary of the Invention

[0016] Compared with the prior art, the advantages of the present invention are as follows:

[0017] 1. By utilizing the synergistic effect of the first electric push rod and the first motor, while pushing the sealing ring through the push ring, the material driving wheel can orderly send the sealing ring to the corresponding sealing groove on the valve core. Moreover, balls are installed on the outer surface of the sleeve, significantly reducing the friction between the sealing ring and the sleeve, enabling the sealing ring to be easily, quickly, and accurately installed into each sealing groove of the valve core. The entire installation process is simple, fast, and completely automated, not only greatly reducing the labor cost and operation error, but also reducing the downtime, optimizing the production process, thus effectively improving the production efficiency of the solenoid valve core processing, and at the same time ensuring the consistency and reliability of the product.

[0018] 2. By using the appearance detection device to identify whether the sealing ring in each sealing groove is installed in place. When the sealing ring deviates, the movement of the valve core is immediately stopped, and the second electric push rod and the driving 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 into the sealing groove. The design of the guide plate not only reduces the difficulty of the rocker inserting between the sealing ring and the valve core, but also through the cooperation of the sliding plate and the first spring, prevents the sealing ring from getting stuck, ensuring a smooth and efficient reset process. In addition, the arc-shaped structure of the rocker and the ingenious design of the guide plate closely adhering to the inclined surface of the outer edge of the sealing groove further improve the success rate of the sealing ring reset, avoiding dead angle problems. The entire device has a high degree of automation, can quickly respond and complete the reset when the sealing ring deviates, significantly improving the product quality and production efficiency, while reducing manual intervention and operation error, and lowering the production cost.

[0019] 3. When the seesaw guides the sealing ring back into the sealing groove, the movement of the sealing ring drives the lever to move, thereby pushing the pressure rod out of the semi-circular groove and pressing the sealing ring tightly. Moreover, under the combined action of the semi-circular groove restricting the movement of the collar and the pressure rod pressing the sealing ring tightly, the collar can rotate synchronously with the valve core, so that the pressure rod plays a role in fixing the sealing ring at a fixed point, avoiding the sealing ring that has entered the sealing groove from disengaging again when the seesaw pries the sealing ring at other positions later, and further ensuring that the sealing ring will not disengage from the sealing groove again after resetting. Based on the above advantages, it not only significantly improves the efficiency and reliability of the sealing ring reset, but also avoids the problem of the sealing ring disengaging again, further ensuring the high efficiency of the solenoid valve spool processing and the stability of the product quality.

DETAILED DESCRIPTION

[0034] 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.

[0035] 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;

[0036] 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.

[0037] 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 .

[0038] 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 .

[0039] 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.

[0040] In the processing of the multi-way solenoid valve spool combination in a straight rod shape, for the installation of the spool sealing ring in the traditional method, mechanical equipment is used to install the sealing rings 13 in the sealing grooves 32 at both ends of the spool, or multiple sealing rings 13 are manually installed one by one into each sealing groove 32 on the spool 31. In the present invention, the sealing rings 13 to be installed are first sequentially installed outside the sleeve 11, and the external conveying device sequentially pushes the first electric push rod 21 from the starting end of the sleeve 11 and ejects it from the end of the sleeve 11. 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 by the long rod 22 to slide outside the sleeve 11, and the push ring 23 pushes several sealing rings 13 to slide outside the sleeve 11. The push ring 23 is provided with notches corresponding to the number and positions of several driving wheels 25 one by one, and the notches just avoid each driving wheel 25, which can prevent the push ring 23 from colliding with the driving wheels 25 when sliding to the end of the sleeve 11. Since the outer surface of the sleeve 11 is provided with balls 12, when the sealing ring 13 slides on the surface of the sleeve 11, the frictional force between the sealing ring 13 and the sleeve 11 drives the balls 12 to roll, which can greatly reduce the frictional force between the sealing ring 13 and the sleeve 11, thereby achieving the effect that the push ring 23 can easily push several sealing rings 13 to move. The first electric push rod 21 drives the push ring 23 to push the sealing ring 13 to move through the long rod 22, forming an orderly feeding. Subsequently, the first motor 24 drives the driving wheels 25 to rotate, and the sealing ring 13 pushed by the push ring 23 can just be abutted by the teeth on the driving wheels 25 (the last sealing ring 13 at the end of the sleeve 11), so that under the pushing force of the continuous rotation of the driving wheels 25, it falls off from the end of the sleeve 11 and then is sleeved into the corresponding sealing groove 32 on the spool 31. The first electric push rod 21 and the first motor 24 are both started at intervals, and the conveying device pushes the spool 31 to slide inside the sleeve 11. When each sealing groove 32 on the spool 31 reaches the end of the sleeve 11, the first electric push rod 21 and the first motor 24 will be started. The whole process of installing the sealing ring 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 spool processing.

[0041] Embodiment 2. This embodiment is an explanatory description made on the basis of Embodiment 1. Specifically, 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.

[0042] 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.

[0043] 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). Figure 12 In some cases shown in the figure), the sealing ring 13 needs to be reset in time to avoid unqualified products.

[0044] First, an appearance detection device and a second electric push rod 41 are arranged near the tail end of the casing 11. The appearance detection 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 detection device and the second electric push rod 41 are on the same vertical line. When the valve core 31 passes by, the appearance detection device identifies and detects the sealing ring 13 on each sealing groove 32. When it is found that the position of the sealing ring 13 deviates, the conveying device, the first electric push rod 21 and the first motor 24 all stop operating. Then, the second electric push rod 41 is started (the second electric push rod 41 is in the extended state in the initial state), driving the truss 42 to move. The truss 42 drives the semi-circular shell 61 to approach the valve core 31, and finally the driving wheel 45 abuts against the surface of the valve core 31, and the semi-circular shell 61 surrounds the valve core 31 (the semi-circular shell 61 is designed as a semi-circular structure). Subsequently, the second motor 44 is started, and the second motor 44 drives the driving wheel 45 to rotate. Since the driving wheel 45 abuts against the surface of the valve core 31, the driving wheel 45 can drive the valve core 31 to rotate synchronously.

[0045] In the initial state, the rocker 54 on the side of the housing 43 is on both sides of the corresponding sealing groove 32 (i.e., the sealing groove 32 where the sealing ring 13 is displaced), and is far away from this sealing groove 32; the first spring 57 in the chute 55 pushes the slide plate 56 under the action of elastic force, so that it is at one end of the chute 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 54.

[0046] 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.

[0047] 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.

[0048] Since the outer sides of the convex parts on both sides of the sealing groove 32 are inclined surfaces, when one end of the rocker 54 tilts up, the guide plate 58 loses the block on both sides of the sealing groove 32, slides out from the bottom of the rocker 54 again under the elastic force of the first spring 57, and as the rocker 54 tilts up, the end of the guide plate 58 always abuts against the inclined surfaces on the outer sides of both sides of the truss 42, thus avoiding dead corners and preventing the sealing ring 13 from getting stuck in the gap between the rocker 54 and the outside of the sealing groove 32 during the process of being guided into the sealing groove 32, and improving the success rate of the reset of the sealing ring 13. Moreover, during the process of the guide plate 58 sliding out from the bottom of the rocker 54, it drives the sliding plate 56 to slide inside the sliding groove 55, and the sliding plate 56 can also play a role in pushing the sealing ring 13, which not only prevents the sealing ring 13 from not moving, but also can push the sealing ring 13 to accelerate the sealing ring 13 into the sealing groove 32.

[0049] Embodiment 3, this embodiment is an explanatory description made on the basis of Embodiment 1. Specifically, please refer to Figures 1 to 12 , a semi-circular shell 61 is installed at the bottom in the middle of the truss 42. A semi-circular groove 62 is provided inside the semi-circular shell 61. A number of limiting female teeth 63 are provided on the inner wall of the semi-circular groove 62. A ejector rod 64 is installed on the inner wall at the lower end of the semi-circular groove 62. Two push blocks 65 are installed alternately inside the upper end of the semi-circular shell 61. A dial rod 66 is fixed to the outer end of each push block 65. Two second springs 67 are installed alternately inside the upper end of the semi-circular shell 61. Each push block 65 and dial rod 66 are elastically connected to the semi-circular shell 61 through the corresponding second spring 67.

[0050] A third spring 71 is installed inside the upper end of the semi-circular shell 61. A collar 72 is slidably connected inside the semi-circular groove 62. One end of the third spring 71 is installed on the side of the collar 72. Two pulleys 73 are rotatably connected to both sides of the collar 72. The pulleys 73 are slidably connected inside the semi-circular groove 62. A pressure rod 74 is slidably connected inside the collar 72. A fourth spring 75 is sleeved outside the pressure rod 74, and the pressure rod 74 is elastically connected to the collar 72 through the fourth spring 75. A limiting groove 76 is provided on the side of the pressure rod 74. A wedge-shaped platform 77 is installed at 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 female tooth 63.

[0051] A rotating shaft 81 is rotatably connected inside the side of the collar 72. 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 collar 72 through the torsion springs 82. A limiting block 84 and a fifth spring 85 are installed inside the collar 72. The limiting block 84 is elastically connected inside the collar 72 through the fifth spring 85, and one end of the control plate 83 abuts against the end of the limiting block 84.

[0052] In order to ensure the efficient reset of the sealing ring 13, a semi-circular shell 61 is also provided in the middle of the truss 42. During the process of the rocker 54 guiding the sealing ring 13 into the inside of the sealing groove 32, there is a convex and a lateral movement towards the sealing groove 32 for the sealing ring 13 below the truss 42. By using this movement of the sealing ring 13, the corresponding toggle lever 66 on one side can be driven to move (as can be seen from the attached drawings of the specification Figure 12 it is known that the offset position of the sealing ring 13 will be on the side where the sealing groove 32 is absent. In all embodiments, the movement of the rocker 54 on the side of the sealing groove 32 without the sealing ring 13 is meaningless, and the corresponding toggle lever 66 will not move), and while the toggle lever 66 drives the push block 65 to squeeze the wedge-shaped platform 77, the second spring 67 is compressed. The wedge-shaped platform 77 moves downward under the extrusion, driving the limit sub-teeth 78 on its top surface to separate from the limit mother teeth 63. The wedge-shaped platform 77 drives the pressure rod 74 to slide towards the collar 72 and slide out of the semi-circular groove 62, abutting against the surface of the sealing ring 13 that has entered the inside of the sealing groove 32. When the wedge-shaped platform 77 drives the pressure rod 74 to slide towards the collar 72, the fourth spring 75 is also compressed, and the limit groove 76 on the surface of the pressure rod 74 slides into the collar 72 and engages with the fifth spring 85 provided inside the collar 72 to limit the movement of the pressure rod 74 and keep it in the state of sliding out of the semi-circular groove 62 and tightly abutting against the sealing ring 13. Since the limit sub-teeth 78 are separated from the limit mother teeth 63 and the pressure rod 74 is pressed tightly against the sealing ring 13, during the synchronous rotation of the valve core 31 and the sealing ring 13, the collar 72 will be driven to slide in the semi-circular groove 62 through the pressure rod 74. During the sliding process of the collar 72 in the semi-circular groove 62, the pressure rod 74 plays a role in fixing the sealing ring 13 at a fixed point, preventing the sealing ring 13 that has already entered the sealing groove 32 from detaching again when the rocker 54 pries the sealing ring 13 at other positions later, thereby ensuring that the sealing ring 13 can efficiently and reliably return to the sealing groove 32. When the collar 72 slides in the semi-circular groove 62, the pulleys 73 at both ends of the collar 72 roll in the semi-circular groove 62, which can greatly reduce the frictional resistance between the collar 72 and the semi-circular groove 62. Even when the pressure rod 74 tightly abuts against the sealing ring 13, the collar 72 can still stably follow the sealing ring 13 to perform circular motion together.

[0053] During the sliding process of the collar 72 in the semi-circular groove 62, the third spring 71 is stretched. When the collar 72 slides to the end of the semi-circular 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 abuts against the ejector rod 64 on the side of the end of the semi-circular groove 62. The ejector rod 64 pushes the control plate 83 to swing, the control plate 83 drives the rotating shaft 81 to rotate, and the torsion spring 82 is wound up. The other end of the control plate 83 swings towards the outside of the collar 72, releasing the limit block 84. 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 further releasing the restriction on the pressure rod 74. Subsequently, under the elastic force of the fourth spring 75, the pressure rod 74 and the wedge-shaped platform 77 rise (in accordance with the attached drawings of the specificationFigure 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.
