Description

Technical Field

[0001] The present invention relates to the technical field of solenoid valve processing, in particular to automatic processing equipment for a solenoid valve body which is convenient for remodeling. Background Art

[0002] The solenoid valve body requires multiple threaded holes, slots, and air holes for connection. These holes are located on different surfaces of the valve body. The machining process typically includes drilling and tapping, with slots also requiring milling. Current production processes often utilize assembly lines, with each step requiring independent processing equipment. This requires a large number of equipment and operators, resulting in high costs and low overall efficiency.

[0003] Chinese patent authorization announcement number CN107443083B discloses a multi-station automatic processing device for solenoid valve bodies, including a processing table with a turntable at its center. Surrounding the turntable are multiple processing devices, including a loading device, a device for drilling two holes diagonally opposite the front side of the valve body, a device for tapping two holes diagonally opposite the front side of the valve body, and a device for drilling a single hole in the upper left corner of the front side of the valve body. This patent utilizes a dedicated fixture to secure the valve body and coordinates it with a rotating downward pressure cylinder for positioning. However, since all four sides of the valve body must be processed, the contact area between the fixture and the valve body is limited, which can easily cause interference and collision between the fixture and the processing tool. Furthermore, if only the clamping force from above is relied upon, the impact force generated when the tool contacts the valve body during heavy-load drilling operations can cause the valve body to shift, affecting processing accuracy. Furthermore, when replacing different valve bodies, the fixture must be replaced at the same time as the processing device, resulting in low efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application is described in detail below in combination with the drawings and specific embodiments.

[0032] As Figures 1 to 5As shown: An automatic processing equipment for the valve body of an electromagnetic valve that is easy to change, including a turntable 1 and a plurality of processing mechanisms 2 equidistantly distributed around the turntable 1, the turntable 1 is provided with a plurality of clamping seats 15 equidistantly surrounding the axis of the turntable 1; each clamping seat 15 is provided with a rotating component 11 for driving the valve body to rotate and two groups of clamping components 12; each group of clamping components 12 includes two clamping heads 121 that can slide relative to each other; the clamping head 121 has the freedom to move in a direction away from the valve body, and after the rotating component 11 rotates the valve body to a preset processing position, the clamping head 121 located between the processing mechanism 2 and the valve body avoids the processing mechanism 2 by moving, and the avoidance action is synchronized with the start signal of the processing mechanism 2.

[0033] This automatic processing equipment achieves multi-faceted processing of valve bodies through the coordinated action of a turntable 1, a rotating assembly 11, a clamping assembly 12, and a processing mechanism 2. During operation, the turntable 1 moves synchronously along multiple clamping seats 15 equidistantly distributed along the circumference, causing the valve body to pass through multiple processing mechanisms 2 in sequence to complete different processes.

[0034] When the valve body reaches the target processing position, the rotating component 11 will drive the valve body to rotate around its own axis, and accurately adjust the surface to be processed to the preset position facing the processing mechanism 2. Subsequently, the clamping heads 121 of the two sets of clamping components 12 slide relative to each other in the radial direction, thereby applying a clamping force to the four sides of the valve body to ensure that the valve body remains stable during the processing. It should be noted that the two sets of clamping components 12 are not started synchronously when clamping the valve body. Since the valve body has a rectangular structure, the valve body is first clamped by one set of clamping components 12, and then clamped by the other set of clamping components 12, so as to avoid the problem of inadequate clamping due to the different distances between the clamping components 12 and the side of the valve body.

[0035] At this time, after the turntable 1 drives the valve body to move to the processing mechanism 2, the clamping head 121 located between the processing mechanism 2 and the valve body will interfere with the action during processing. The clamping head 121 moves away from the valve body to avoid the processing mechanism 2, and this avoidance action is strictly synchronized with the start signal of the processing mechanism 2 to ensure that there are no obstacles when the processing mechanism 2 is working. It should be noted that the other three clamping heads 121 located on the side of the valve body will not move at this time to ensure the stability of the valve body during processing. After the processing is completed, the clamping head 121 is reset to the initial position, the two sets of clamping components 12 release the valve body at the same time, the rotating component 11 moves again to switch to the next surface to be processed, and the turntable 1 synchronously transports the valve body to the next workstation. The above cycle is repeated until all processing surfaces are processed.

[0036] The cooperation of the rotating assembly 11 and the clamping assembly 12 enables the valve body to switch the surface to be machined by rotation without multiple disassembly and assembly, and the continuous movement of the clamping seat 15 driven by the rotating disc 1 realizes the orderly circulation of multiple machining surfaces between different machining mechanisms 2, reduces the waiting time between processes, and improves the machining continuity. At the same time, the above-mentioned mode enables the equipment to flexibly cope with the machining requirements of rectangular valve bodies of different sizes, and does not need to replace all jigs due to the replacement of the valve body, thereby reducing the changeover time and steps, improving the compatibility of the equipment for multiple valve body models, and enhancing the flexibility and adaptability in the production process.

[0037] By moving the clamping head 121 away from the valve body to avoid interference, and synchronizing with the machining mechanism 2 start signal, the interference between the clamping head 121 and the machining tool 2111 is completely avoided, the complete exposure of the surface to be machined is ensured, the conditions for high-precision machining are provided, and the equipment damage and machining interruption caused by interference are reduced. At the same time, by the clamping mode of the clamping head 121 to the valve body, the top of the valve body can be exposed, thereby facilitating direct machining of the top of the valve body, cooperating with the turnover mechanism, enabling all six surfaces of the valve body to be machined, or by placing the valve body vertically in the clamping seat 15, by rotating the vertical valve body, the machining of the top and bottom of the valve body can also be realized without replacing the jig.

[0038] As shown in Figures 1 to 5 The sliding directions of the clamping heads 121 of the two sets of clamping assemblies 12 are perpendicular to each other, the clamping seat 15 is provided with installation grooves 1211 which are the same as the number of the clamping heads 121 and one-to-one corresponding, each installation groove 1211 is provided with a telescopic shaft 1212 which is parallel to the sliding direction of the clamping head 121, and the clamping head 121 is fixedly connected to one end of the telescopic shaft 1212 close to the center of the clamping seat 15.

[0039] When the valve body is conveyed to the preset position on the clamping seat 15, the telescopic shaft 1212 of one of the clamping assemblies 12 drives the clamping head 121 to move in the sliding direction thereof towards the valve body, until the two clamping heads 121 of the clamping assembly 12 contact and apply initial clamping force to two opposite sides of the valve body, completing the preliminary positioning of the valve body in one direction; then, the telescopic shaft 1212 of the other clamping assembly 12 drives the clamping head 121 thereof to move in the same way, contacts and applies clamping force to the other two opposite sides of the valve body, and since the sliding directions of the two clamping heads 121 are perpendicular to each other, the four sides of the valve body are stably clamped in all directions.

[0040] It should be noted that the driving of the telescopic shaft 1212 is preferably driven by an external air source, and two independent air paths can be provided in the clamping seat 15 to control the corresponding telescopic shaft 1212 of the clamping head 121 of the two clamping assemblies 12.

[0041] The perpendicular sliding directions of the two clamping assemblies 12 ensure a more balanced force distribution when clamping the valve body. Compared to traditional single-direction clamping methods, this significantly improves the stability of the valve body during processing, reduces machining errors caused by uneven force, and improves machining accuracy. Furthermore, the movement of the clamping head 121, driven by the telescopic shaft 1212, allows for flexible adjustment of the clamping position and force based on the size of the valve body, enhancing the device's adaptability to valve bodies of varying specifications.

[0042] like Figures 1 to 5 As shown: the clamping head 121 includes a clamping block 1213 and a positioning pin 1214. The top surface of the clamping block 1213 is flush with the top surface of the clamping seat 15. Each clamping block 1213 is provided with a positioning hole 1215 extending in the vertical direction. The positioning pin 1214 is sleeved in the positioning hole 1215 and elastically connected thereto.

[0043] Before the valve body is transported to the clamping seat 15, since the positioning pin 1214 is elastically connected to the positioning hole 1215, the positioning pin 1214 can be in a lifted state through the elastic member, protruding from the top surface of the clamping block 1213, providing a pre-positioning reference for the placement of the valve body.

[0044] When the valve body reaches the preset position, the clamping heads 121 of the two groups of clamping assemblies 12 slide relative to each other in the horizontal direction, driving the positioning pins 1214 to move synchronously toward the valve body. The positioning pins 1214 first contact the side of the valve body to fix the valve body, thereby achieving stable clamping of the valve body; when processing the side of the valve body, by starting the circuit of the positioning pins 1214 on the clamping block 1213 between the processing mechanism 2 and the valve body, the positioning pins 1214 can overcome the elastic force of the elastic member, so that the positioning pins 1214 can be retracted into the positioning holes 1215. Since the top surface of the clamping block 1213 is flush with the top surface of the clamping seat 15, the processing mechanism 2 can process the valve body without obstacles, avoiding collision with the clamping assembly 12; after the processing is completed, the power supply of the electromagnetic drive unit is disconnected, and the positioning pins 1214 are re-lifted and reset under the action of the elastic member to prepare for the next cycle.

[0045] The locating pin 1214 is naturally maintained in an elevated position by an elastic member, providing a stable pre-positioning reference for the valve body without the need for additional drive. When the valve body is transported to the clamping seat 15, the protruding locating pin 1214 can guide the valve body to quickly fall into the preset position, reducing the alignment adjustment time during manual or robotic placement and improving the convenience and efficiency of clamping. When the two sets of clamping assemblies 12 drive the locating pin 1214 to move toward the valve body, the locating pin 1214 first contacts the side of the valve body to form a fixed position, and then cooperates with the subsequent close fit of the clamping head 121. Through the dual effects of pre-positioning and clamping, the stability of the valve body during the processing is enhanced, the risk of processing offset due to loose clamping is reduced, and it is conducive to improving processing accuracy.

[0046] like Figures 2 to 7 As shown, the rotating assembly 11 includes a rotating cylinder 111 arranged at the bottom of the clamping seat 15, and a rotatable rotating head 112 is arranged in the center of the clamping seat 15. The rotating head 112 is transmission-connected to the rotating cylinder 111.

[0047] If it is necessary to process other sides of the valve body, the rotary cylinder 111 starts and outputs torque, and transmits power to the rotary head 112 located in the center of the clamping seat 15 through a transmission connection, driving the rotary head 112 to rotate around its own axis. Since the valve body is placed on the rotary head 112, the rotation of the rotary head 112 synchronously drives the valve body to rotate, so that the surface of the valve body to be processed is accurately aligned with the processing mechanism 2; when the valve body rotates to the preset processing position, the rotary cylinder 111 stops and locks the position of the rotary head 112 to ensure that the valve body remains stable during the processing, and the valve body is fixed by the two clamping assemblies 12; after the current side processing is completed, if it is necessary to switch to the next processing surface, the clamping assembly 12 releases the clamping and is started again by the rotary cylinder 111, and the above rotation and positioning process is repeated until all sides of the valve body that need to be processed are completed.

[0048] By directly driving the rotary head 112 with the rotary cylinder 111, the multi-faceted machining of the valve body is achieved in a single clamping operation. This avoids the tedious process of multiple disassembly and repositioning of the valve body required in traditional machining methods, significantly shortening the machining cycle and improving production efficiency. The precise control of the rotary cylinder 111 ensures the angular accuracy of each valve body rotation. Combined with the stable clamping of the valve body by the clamping assembly 12, this effectively reduces positioning errors caused by multiple clamping operations and improves the positional accuracy and surface quality of the various machined surfaces of the valve body.

[0049] like Figures 2 to 7 As shown: the rotating cylinder 111 is provided with a transmission shaft 1111 fixedly connected thereto, the rotating head 112 is sleeved on the transmission shaft 1111, and the rotating head 112 is rotatably provided on the clamping seat 15 and elastically connected to the clamping seat 15, a conical transmission block 1121 is provided at the bottom of the rotating head 112, and a slider 113 that can slide in a horizontal direction is provided inside the clamping seat 15, next to the transmission block 1121, and a pulley 1131 is provided on the side of the slider 113 close to the transmission block 1121.

[0050] When the valve body processing completes the current process and the clamping assembly 12 is released, the slider 113 inside the clamping seat 15 moves horizontally toward the transmission block 1121, and the pulley 1131 on the slider 113 first contacts the conical surface of the transmission block 1121. As the slider 113 continues to move, the pulley 1131 rolls along the conical surface and generates an upward thrust, forcing the transmission block 1121 to drive the transmission shaft 1111 to slide upward; since the rotating head 112 is connected to the transmission block 1121 and is sleeved on the transmission shaft 1111, the sliding of the transmission block 1121 drives the rotating head 112 to rise synchronously, and since the rotating head 112 can be rotatably arranged on the clamping seat 15, the rotating head 112 is now The elastic connection between 112 and the clamping seat 15 is compressed, and the rotating head 112 lifts the valve body to the top surface that is separated from the clamping seat 15; then the rotating cylinder 111 is started, and the rotating head 112 and the valve body are driven to rotate together to the preset angle of the next surface to be processed through the transmission shaft 1111, and the pulley 1131 maintains contact with the transmission block 1121 during the rotation process to provide stable support; after being rotated into place, the slider 113 slides in the opposite direction, and the pulley 1131 is separated from the thrust on the transmission block 1121, and the rotating head 112 is reset downward along the transmission shaft 1111 under the action of the elastic connection, and the valve body falls back into the clamping seat 15, and the clamping assembly 12 clamps the valve body again for subsequent processing.

[0051] Since the valve body has a rectangular structure, after the clamping head 121 releases the valve body, when the valve body is driven by the rotating assembly 11, the valve body, due to its rectangular structure, is easily collided with the clamping head 121. Because the slider 113 contacts the tapered surface of the transmission block 1121 via the pulley 1131, the rotating head 112 can drive the valve body to rise, allowing the valve body to effectively avoid the clamping head 121, thereby ensuring the accuracy of the valve body's rotation and preventing damage to the valve body or displacement of its position due to collision with the clamping head 121.

[0052] The setting of the pulley 1131 can convert sliding friction into rolling friction, greatly reducing the wear between components and extending the service life of the equipment. At the same time, it reduces the power required to drive the slider 113, and improves the smoothness and response speed of the movement; the elastic connection between the rotating head 112 and the clamping seat 15 enables the rotating head 112 to automatically reset when there is no external force, without the need for an additional reset mechanism, simplifying the overall structure and reducing the risk of failure; by lifting the valve body to separate it from the top surface of the clamping seat 15 and then rotating it, the friction between the valve body and the clamping seat 15 is avoided, ensuring a smooth and accurate rotation process, and reducing the damage to the valve body surface and positioning errors caused by friction; the cooperation of the pulley 1131 and the conical surface can adapt to the requirements of different lifting heights. When processing valve bodies of different thicknesses, it is only necessary to adjust the moving distance of the slider 113 to achieve adaptation without replacing parts, thereby enhancing the compatibility of the equipment with diverse valve bodies.

[0053] like Figure 1 、 Figure 2 、 Figures 8 to 10 As shown, the processing mechanism 2 includes a mounting frame 21 and a tool holder 211 rotatably arranged on the mounting frame 21 , and a plurality of cutting tools 2111 equidistantly arranged around the rotation axis of the tool holder 211 are arranged on the tool holder 211 .

[0054] After the turntable 1 transports the valve body to the processing position and is stably fixed by the clamping assembly 12, the tool holder 211 on the mounting frame 21 starts to rotate. According to the requirements of the current processing process, the corresponding tool 2111 is rotated to a position facing the surface of the valve body to be processed, so that the surface of the valve body to be processed is subjected to cutting, drilling and other processing operations by the tool 2111; when the process is completed, the tool holder 211 continues to rotate and switches to the tool 2111 adapted to the process. At this time, the turntable 1 may drive the valve body to move to the corresponding processing position or the clamping assembly 12 to adjust the valve body angle, or it may wait at the original position until all processes on the current processing surface are completed and then rotate to the next position to be processed, and repeat the above processing process until all processes of the valve body at the processing mechanism 2 are completed.

[0055] By integrating multiple tools 2111 on the same tool holder 211, multiple processing steps of the valve body can be completed without frequently replacing the tools 2111, reducing the time interval for replacing the tools 2111 and improving processing continuity; the tools 2111 on the tool holder 211 are evenly distributed around the rotation axis of the tool holder 211, so that the rotation angle of the tools 2111 is fixed when switching, which facilitates the precise positioning of the required tools 2111 through the control system, ensuring the accuracy and consistency of tool change; the rotation coordination between the tool holder 211 and the mounting frame 21 can adapt to the diverse requirements of different types of valve bodies for tools 2111. When processing different valve bodies, the corresponding tool 2111 can be switched by simply adjusting the rotation position of the tool holder 211 through the program without disassembling or replacing the tool holder 211, simplifying the model change process and enhancing the adaptability of the equipment to various processing tasks; at the same time, the integrated tool 2111 layout saves installation space, makes the structure of the processing mechanism 2 more compact, and is conducive to forming efficient cooperation with the clamping seat 15 on the turntable 1, further improving the overall processing efficiency.

[0056] like Figure 1 、 Figure 2 、 Figures 8 to 10 As shown, a rotatable conical toothed disc 22 is provided on the mounting frame 21 , and each cutter 2111 is provided with a bevel gear 23 meshingly connected with the conical toothed disc 22 .

[0057] When the tool holder 211 rotates to align the target tool 2111 with the surface of the valve body to be machined, the conical gear disc 22 on the mounting frame 21 begins to rotate, and through the meshing transmission of the conical gear disc 22 and the bevel gear 23 on the tool 2111, all tools 2111 are driven to rotate synchronously, thereby realizing high-speed rotation to perform cutting, drilling and other machining actions; when it is necessary to replace the tool 2111, the tool holder 211 rotates to drive all tools 2111 to revolve around the axis of the mounting frame 21, and the tool 2111 required for the next process is switched to; at this time, the conical gear disc 22 continues to rotate, and the newly switched tool 2111 immediately obtains the rotation power through the meshing of the bevel gear 23 and the gear disc, seamlessly connects the subsequent machining task, and the whole process does not need to interrupt the rotation of the conical gear disc 22. The machining mechanism 2 only needs one power source to drive all tools 2111 to rotate, simplifies the transmission structure, and reduces the equipment cost and maintenance difficulty; the rotation power of the tool 2111 directly comes from the conical gear disc 22 on the mounting frame 21, avoiding the complexity of separately configuring a driving device for each tool 2111 in the traditional multi-tool 2111 system, making the structure of the machining mechanism 2 more compact and reducing the occupied space.

[0058] As shown in Figure 1 , Figure 2 , Figures 8 to 10 : The mounting frame 21 is provided with an annular slide rail 212, and the conical gear disc 22 is located inside the slide rail 212 on the mounting frame 21. Each tool 2111 is provided with a mounting shaft 2112 that can slide along the axial direction thereof, and the mounting shaft 2112 is sleeved with an adjusting frame 2113 that is in sliding cooperation with the slide rail 212. The slide rail 212 includes a driving part 2121 for driving the adjusting frame 2113 to move close to the conical gear disc 22 and a retaining part 2122 for driving the adjusting frame 2113 to move away from the conical gear disc 22.

[0059] When the tool holder 211 drives the tool 2111 to rotate to a specific work station around the mounting frame 21, the adjusting frame 2113 synchronously slides on the slide rail 212 with the tool 2111; when the adjusting frame 2113 enters the driving part 2121 area of the slide rail 212, the curve structure of the driving part 2121 forces the adjusting frame 2113 to move along the axial direction of the mounting shaft 2112 to the conical tooth disc 22, thereby driving the bevel gear 23 on the tool 2111 to gradually mesh with the conical tooth disc 22, at this time the rotation of the conical tooth disc 22 drives the tool 2111 to high-speed rotation through gear transmission, and the valve body is processed; when the process is completed, the tool holder 211 continues to rotate to make the adjusting frame 2113 enter the retaining part 2122 area of the slide rail 212, the structure of the retaining part 2122 guides the adjusting frame 2113 to move away from the conical tooth disc 22 along the axial direction of the mounting shaft 2112, so that the bevel gear 23 and the conical tooth disc 22 are disengaged, and the tool 2111 stops rotating; the tool holder 211 continuously rotates to deliver the tool 2111 required for the next process to the processing position, and the above process of switching the adjusting frame 2113 between the driving part 2121 and the retaining part 2122 is repeated, so that the automatic rotation of different tools 2111 is realized. In the whole process, the ring structure of the slide rail 212 matches the rotation path of the tool holder 211, which ensures that the adjusting frame 2113 can smoothly transition between the driving part 2121 and the retaining part 2122, and the axial sliding degree of freedom of the mounting shaft 2112 ensures the reliable meshing and disengaging of the bevel gear 23 and the conical tooth disc 22.

[0060] The driving part 2121 and the retaining part 2122 of the slide rail 212 automatically control the meshing and disengaging of the tool 2111, realize the full automation of the rotation of the tool 2111, do not need additional power devices or manual intervention, simplify the operation process and improve the processing efficiency; the tool holder 211 rotates to complete the switching of the tool 2111 state synchronously, reduces the waiting time required by the traditional tool changing mechanism, and shortens the single-process processing period.

[0061] As shown in Figures 1 to 3 and Figure 11 : The rotating disc 1 is provided with the same number of slide grooves 13 as the clamping seats 15 and one-to-one correspondence, the slide grooves 13 extend along the radial direction of the rotating disc 1, the clamping seats 15 are slidably arranged on the slide grooves 13, and the central part of the rotating disc 1 is provided with a fixed seat 14, and the fixed seat 14 is provided with the same number of linear drives 141 as the machining mechanisms 2 and one-to-one correspondence, and the linear drives 141 are used to drive the clamping seats 15 to move to the machining mechanisms 2.

[0062] When the turntable 1 drives the clamping seat 15 to rotate to the workstation corresponding to the processing mechanism 2, the linear actuator 141 on the fixed seat 14 corresponding to the processing mechanism 2 is activated, pushing the clamping seat 15 to slide along the slide groove 13 toward the processing mechanism 2, so that the valve body is precisely close to the working range of the processing tool 2111; after the processing mechanism 2 completes the current process, the linear actuator 141 drives the clamping seat 15 to slide back along the slide groove 13 and return to its original position away from the processing mechanism 2; then the turntable 1 continues to rotate, transporting the clamping seat 15 to the next workstation of the processing mechanism 2, at which time the corresponding linear actuator 141 is activated again, repeating the above sliding action until the valve body completes all processing steps. Throughout the entire process, the slide groove 13 guides the sliding of the clamping seat 15, ensuring its stable movement trajectory, and the sliding actions of all clamping seats 15 are independently controlled by their corresponding linear actuators 141 without interfering with each other.

[0063] By pushing the clamping seat 15 to slide radially through the linear drive 141, the distance between the valve body and the processing mechanism 2 can be flexibly adjusted, so that the same equipment can be adapted to valve bodies of different sizes or different processing depth requirements without replacing the turntable 1 or the clamping seat 15, which significantly improves the versatility of the equipment; each processing mechanism 2 corresponds to an independent linear drive 141, so that the sliding action of each workstation can be controlled separately. When it is necessary to adjust the processing distance of a certain process, it is only necessary to adjust the parameters of the corresponding drive, which simplifies the debugging process during the changeover.

[0064] like Figures 3 to 5 As shown: each clamping head 121 is provided with a sensor 1216 for monitoring the clamping pressure.

[0065] The pressure sensor 1216 on each clamping head 121 monitors the pressure exerted by the clamping head 121 on the valve body in real time while the clamping assembly 12 is operating, continuously transmitting the pressure signal to the control system at the back end of the device. As the clamping head 121 begins to move toward the valve body and gradually contacts it, the sensor 1216 detects the gradual increase in pressure. The control system then determines whether the current clamping force is appropriate based on a preset pressure range. If the pressure reaches the standard value for the appropriate valve body model, the control system immediately issues a signal to stop the movement of the clamping head 121, ensuring that the clamping force remains stable within a safe range.

[0066] Real-time monitoring by sensor 1216 enables precise control of the clamping force, avoiding the problem of loose clamping due to improper force in traditional clamping methods. Different pressure parameters can be preset for different types of solenoid valve bodies through the control system. Sensor 1216 cooperates with the system to quickly adapt to the corresponding clamping force, and there is no need to manually adjust the clamping component 12.

[0067] The above embodiments merely represent one or more embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present invention, and such modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the appended claims.
