Description

Technical Field

[0001] The invention relates to the technical field of valve ball production and manufacturing, and in particular to an automatic production device and a production method for a valve ball with integrated deburring. Background Art

[0002] Valves are mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. They can adjust and control the fluid by rotating with a small torque, so they are widely used in various industries. The key component of the valve is the valve ball, which is a sphere with channels inside and grooves on the side wall. It can be opened and closed by rotating to change the connection in different directions.

[0003] During the production process, the valve ball is formed by machining a ball blank, and the outside of the ball blank does not have grooves, which cannot meet the needs of multi-channel use. Further grooving treatment is required before it can be used. However, during the grooving process, especially for stainless steel balls, burrs will be generated after grooving, which requires further grinding to remove the burrs.

[0004] like Figure 1 The structure of the ball blank 100 is shown, and the ball blank 100 comprises a sphere 101, a main channel 102, an inner wall 103, an outer wall 104 and two ridges 107, the main channel 102 is arranged inside the sphere 101 and penetrates the sphere 101, the inner wall 103 and the outer wall 104 form the inner wall and the outer wall of the sphere 101, and the outer wall 104 is surrounded by the outside of the main channel 102, and the two ridges 107 are located at the two ends of the outer wall 104 and near the port of the main channel 102. And the ball blank 100 is a stainless steel material, and further grooves need to be made in the outer wall to meet the demand of the ball valve sphere, and the outer wall 103 and the inner wall 104 are both roughcast states, rusty, and need to be processed and ground to reach the required size and smoothness. Therefore, the ball blank 100 needs further production and processing to meet the various demands of the production ball valve.

[0005] At present, the equipment used to produce valve balls is a single-function equipment. Different equipment is needed to process the inner and outer walls of the valve balls respectively, and a separate slotting machine is needed to slot the valve balls. After slotting, burrs will be generated and the valve balls cannot be used. The burrs need to be removed manually, which takes a long time, resulting in low production efficiency and high cost of valve balls. In addition, different equipment works separately, and each step needs to be manually transferred to the next step, resulting in the inability to unify the production process of valve balls and a large number of defective products. In today's era with high requirements for quality and automation, this single-operation manufacturing process can no longer meet the quality and efficiency requirements of industrial production. Therefore, there is an urgent need for a fully automated equipment to further process and manufacture the ball blanks to meet production needs. Summary of the invention

[0062] In this embodiment, the deburring integrated valve ball automated production equipment includes a loading platform 200, a working device 300, a moving device 400, a processing drive device 500, a mobile drive device 600, a control console 700 and a unloading platform 800, wherein the loading platform 200 is connected to the working device 300, wherein the ball blank 100 is placed on the loading platform 200 and waits for processing, the moving device 400, the processing drive device 500 and the mobile drive device 600 are all arranged on the working device 300, wherein the control console 700 is connected to the working device 300, the loading drive device 500 and the mobile drive device 600 The control console 700 is used for inputting and adjusting processing parameters, and controlling the mobile driving device 600 to drive the mobile device 400 to take out the ball blank 100 from the loading platform 200 and transfer it to the working device 300, and controlling the processing driving device 500 to drive the working device 300 to process the ball blank 100. The mobile driving device 600 is used to drive the mobile device 400 to move the ball blank 100 from the loading platform 200 to each processing platform of the working device 300 for processing into a finished product for use in a ball valve.

[0063] The working device 300 includes a first processing platform 301, a second processing platform 302, a third processing platform 303, a fourth processing platform 304 and a frame 305. The first processing platform 301, the second processing platform 302, the third processing platform 303 and the fourth processing platform 304 are sequentially connected and arranged inside the frame 305, wherein the loading platform 200 is located outside the frame 305 and connected to the first processing platform 301. The ball blank 100 is sequentially moved from the loading platform 200 to the first processing platform 301, the second processing platform 302, the third processing platform 303 and the fourth processing platform 304. The four processing platforms perform their respective functions and cooperate with each other, so that the ball blank 100 is processed by inner wall processing, outer wall processing, groove milling and deburring at the four processing platforms in sequence.

[0064] The processing drive device 500 includes a first processing drive component 501, a second processing drive component 502 and a third processing drive component 503, wherein the first processing drive component 501 is arranged on the first processing platform 301, the second processing drive component 502 is arranged on the second processing platform 302, and the third processing drive component 503 is arranged on the third processing platform 303 and the fourth processing platform 304, wherein the processing drive device 500 can be implemented as a servo drive system to drive the movement of components such as tools and slides in the four processing platforms to process the ball blank 100.

[0065] like Figure 5 As shown, the first processing platform 301 includes a first loading position 3011, a first tool assembly 3012 and a clamping assembly 3013, the clamping assembly 3013 is connected to the first loading position 3011, and the first tool assembly 3012 can grind the inner wall of the ball blank 100 of the first loading position 3011 to complete the processing step by step by rotation. Specifically, the first loading position 3011 is used to receive the ball blank 100 transferred from the loading platform 200 by the moving device 400, and the clamping assembly 3013 clamps and fixes the ball blank 100 in a second axis (i.e., the Y-axis) direction, so that the main channel 102 of the ball blank 100 is placed along the Y-axis direction, so that the tool head of the first tool assembly 3012 is inserted into the main channel 102 of the ball blank 100 and fits against the inner wall 103 of the ball blank 100, and then the first tool assembly 3012 is driven to rotate, and the inner wall 103 of the ball blank 100 is gradually ground to make the entire inner wall 103 in the blank state smooth.

[0066] It is worth mentioning that in the present invention, the first axis is positioned as the X-axis, the second axis is the Y-axis, and the third axis is the Z-axis, wherein the movement along the first axis (i.e., the X-axis) is the left-right movement, the movement along the second axis (i.e., the Y-axis) is the front-back movement, and the movement along the third axis (i.e., the Z-axis) is the vertical up-and-down movement.

[0067] The first tool assembly 3012 and the clamping assembly 3013 are both connected to the first processing drive assembly 501, and the clamping assembly 3013 is opened and closed under the drive of the first processing drive assembly 501. After the clamping assembly 3013 is opened, the mobile device 400 places the ball blank 100 on the clamping assembly 3013, and then the clamping assembly 3013 is closed to fix the ball blank 100. When the ball blank 100 is processed on the first processing platform 301, the clamping assembly 3013 is opened again so that the mobile device 400 can take away the processed product. The cycle is repeated successively, thereby achieving the effect of clamping and fixing the ball blank 100.

[0068] The ball blank 100 is sleeved on the outer side of the first tool assembly 3012, and the first tool assembly 3012 is driven by the first processing drive assembly 501 to perform rotational, axial and radial movements. During the movement and rotation, the inner wall 103 of the ball blank 100 is processed to obtain a smooth inner surface 103A, that is, after the inner wall of the ball blank 100 is processed, a first semi-finished valve ball 100A with a smooth inner wall is formed.

[0069] Reference Figure 7 and attached Fig.13 As shown, the second processing platform 302 includes a second loading position 3021, a second tool assembly 3022, a support shaft 3023 and a chamfering assembly 3024, the second tool assembly 3022, the support shaft 3023 and the chamfering assembly 3024 are all connected to the second loading position 3021, the first semi-finished valve ball 100A is sleeved on the outside of the support shaft 3023 along the Y-axis direction and then supported and fixed, the support shaft 3023 matches the main channel 102 of the first semi-finished valve ball 100A, the second tool assembly 3022 grinds the outer wall 104 of the first semi-finished valve ball 100A on the outside of the first semi-finished valve ball 100A, and the chamfering assembly 3024 is used to chamfer the outer wall 104 of the first semi-finished valve ball 100A and remove burrs generated during the chamfering process to ensure that the outer surface 104B of the first semi-finished valve ball 100A is a smooth arc surface after processing.

[0070] The second tool assembly 3022 is connected to the second machining drive assembly 502, the support shaft 3023 and the chamfering assembly 3024. Driven by the second machining drive assembly 502, the support shaft 3023 clamps and fixes the first semi-finished valve ball 100A, and rotates and moves. The second tool assembly 3022 rotates and cuts the outer wall 104 of the first semi-finished valve ball 100A. The chamfering assembly 3024 can be implemented as a slide, which can move in both horizontal and vertical directions, that is, along the X-axis and Y-axis directions, so as to remove burrs generated during the chamfering process of the second tool assembly 3022 to ensure the smoothness of the outer surface.

[0071] Through the cooperation of the second tool assembly 3022 and the chamfering assembly 3024, the outer wall of the first semi-finished valve ball 100A is processed, and then a second semi-finished valve ball 100B with a smooth outer wall is obtained. The outer surface 104B of the second semi-finished valve ball 100B has become a smooth arc surface, and the ridge 107 has been cut off, that is, at this time, the inner surface 103A and the outer surface 104B are both smooth. Therefore, after the processing of the first processing platform 301 and the second processing platform 302, the inner wall and outer wall of the ball blank 100 and the chamfers on both sides of the channel opening have been processed, and the second semi-finished valve ball 100B with smooth arc surfaces on both inner and outer walls is obtained.

[0072] The third processing platform 303 includes a third loading position 3031, a third tool assembly 3032, a limiting shaft 3033, a fixing assembly 3034 and a slide 3045. The third tool assembly 3032, the limiting shaft 3033, the fixing assembly 3034 and the slide 3045 are all connected to the third loading position 3031. The third loading position 3031 is used for loading the second semi-finished valve ball 100B processed by the second processing platform 302. After loading, it is supported and limited by the limiting shaft 3033, and fixed by the fixing assembly 3034, and then milled and cut by the third tool assembly 3032 to form an outer groove 105C. When installed in a valve stem to form a ball valve, the outer groove 105C matches the valve stem and rotates to form an outer channel.

[0073] The third driving assembly 503 is connected to the third tool assembly 3032, the limit shaft 3033, the fixed assembly 3034 and the slide 3045. Under the drive of the third processing driving assembly 503, the fixed assembly 3034 moves to tighten the second semi-finished valve ball 100B to the area to be ground, the limit shaft 3033 starts to rotate, the third tool assembly 3032 starts to rotate, and the slide 3045 moves forward along the X-axis direction and the Y-axis direction to perform step-by-step milling and cutting, and cuts out the outer groove 105C that meets the application requirements according to the preset data, wherein the size and depth of the outer groove 105C can be set by the console 700 to meet industrial needs. After cutting, a third semi-finished valve ball 100C is obtained, and the outer wall of the third semi-finished valve ball 100C is processed to form the outer groove 105C.

[0074] Since the third processing platform 303 can position the second semi-finished valve ball 100B transferred from the second processing platform 302 and process it according to preset parameters, it can ensure the uniformity of processing position and processing size, and thus, valve balls with uniform specifications can be manufactured.

[0075] Since the product processed in this application is made of stainless steel, burrs will be generated after cutting, and a number of burrs 106C will be formed on the bottom edge of the outer groove 105C of the third semi-finished valve ball 100C, which needs to be further deburred, otherwise it cannot be used.

[0076] Reference Fig.11 As shown, the fourth processing platform 304 includes a grinding element 3041 and two driving cylinders 3042. The grinding element 3041 and the driving cylinder 3042 are connected to the third loading position 3031 and are driven by the third processing drive assembly 503 to grind burrs generated after the third processing platform 303 mills the groove. After grinding, a finished valve ball 100D is obtained. The outer surface of the finished valve ball 100D is smooth, and the smooth outer groove 105D is obtained after deburring.

[0077] Specifically, the grinding element 3041 and the two driving cylinders 3042 are both connected to the third processing drive assembly 503. After the third processing platform 303 completes the milling groove processing, under the drive of the third processing drive assembly 503, the third tool assembly 3032 moves away from the third semi-finished valve ball 100C, so that the third semi-finished valve ball 100C waits for grinding at the milling groove position, and then the grinding element 3041 is started, one of the driving cylinders 3042 extends, and then the other driving cylinder 3042 extends. At this time, under the coordinated action of the two driving cylinders 3042, the grinding element 3041 is aligned with the burr 106C, the driving cylinder 3042 retracts until the grinding is completed, and the slide 3035 retracts to complete the deburring operation, and the finished valve ball 100D is obtained at this time. That is to say, during the process of groove milling and deburring, the processed valve ball is tightened and fixed in the same predetermined position, and the groove milling and deburring operations can be completed by moving forward and backward along the X-axis direction. The burrs can be deburred immediately after groove milling. The precise positioning of the valve ball ensures the accuracy of the deburring position, and only the burr position is polished without damaging other parts of the valve ball.

[0078] The mobile drive device 600 includes a first mobile drive component 601 and a second mobile drive component 602. The first mobile drive component 601 and the second mobile drive component 602 are implemented as pneumatic slides to drive the mobile device 400 to move along the first axis, the second axis and the third axis, so that the ball blank starts from the loading platform 200 and passes through the first processing platform 301, the second processing platform 302, the third processing platform 303, the fourth processing platform 304 and the unloading platform 800 in sequence to complete fully automated processing.

[0079] The mobile device 400 is installed on the top of the frame 305 and extends to the inside of the frame 305 to move the ball blank 100 to each processing platform inside the working device 300, wherein the mobile device 400 includes a first mobile component 401 and a second mobile component 402, which are respectively connected to the first mobile drive component 601 and the second mobile drive component 602, the first mobile component 401 is responsible for the material collection of the loading platform 200, the material collection and collection of the first processing platform 301, and the material collection of the second processing platform 302, and the second mobile component 402 is responsible for the material collection of the second processing platform 302 and the material collection of the third processing 303. Under the driving action of the mobile drive device 600, the first mobile component 401 and the second mobile component 402 can move in the X-axis, Y-axis and Z-axis directions, and the ball blank 100 can automatically move and operate between the first processing platform 301, the second processing platform 302, and the third processing platform 303, so as to realize fully automated processing.

[0080] Reference Figure 6 As shown, the first moving component 401 includes a first moving frame 4011, a first gripper 4012, a second gripper 4013 and a rotating element 4014, the rotating element 4014 is connected to the first moving frame 4011, the first gripper 4012 and the second gripper 4013 are both connected to the rotating element 4014, and are connected to the first moving drive component 601, under the action of the first moving drive component 601, the first gripper 4012 and the second gripper 4013 can be opened and closed to grasp the processing object, and the rotating element 4014 can drive the first gripper 4012 and the second gripper 4013 to rotate to change the orientation through rotation, so as to better complete the material picking, loading and unloading.

[0081] Reference Figure 8 As shown, the second moving component 402 includes a second moving frame 4021 and a third gripper 4022, and the second moving drive component 602 is connected to the second moving frame 4021 and the third gripper 4022 to control the movement of the second moving frame 4021 and the opening and closing of the third gripper 4022 to perform movement, loading and unloading.

[0082] The first movable frame 4011 and the second movable frame 4021 are both connected to the frame 305 and extend above the top of the frame 305, pass through the top of the frame 305 to work inside the working device 300, and move up and down and left and right along the frame 305, that is, move along the Z-axis and X-axis directions, and then pick up materials at the loading table 200 and move them to the first processing platform 301 for loading. After the processing of the first processing platform 301 is completed, the material is picked up and moved to the second processing platform 302 for loading. After the processing of the second processing platform 302 is completed, the material is picked up and moved to the third processing platform 303 for processing.

[0083] In the present invention, the fully automated preparation method (S100) of the ball blank 100 comprises the following steps:

[0084] (S101) The first gripper 4012 grabs the ball blank 100 at the loading platform 200;

[0085] (S102) The ball blank 100 is transferred to the first processing platform 301 for loading;

[0086] (S103) the first tool assembly 3012 processes the inner wall 103 of the ball blank 100;

[0087] (S104) The second gripper 4013 grabs a first semi-finished valve ball 100A formed after processing on the first processing platform 301, and moves it to the second processing platform 302 for loading;

[0088] (S105) The second tool assembly 3022 processes the outer wall and the end surface of the main channel opening of the first semi-finished valve ball 100A, and the chamfering assembly 3024 performs chamfering processing;

[0089] (S106) The third gripper 4022 grabs a second semi-finished valve ball 100B formed after processing on the second processing platform 302, and transfers it to the third processing platform 303;

[0090] (S107) The third processing platform 303 fixes the second semi-finished valve ball 100B and performs milling processing to obtain a third semi-finished valve ball 100C;

[0091] (S108) After the milling groove processing is completed, the grinding element 3041 is started to grind the burrs generated by the milling groove, and the processing is completed to obtain the finished valve ball 100D.

[0092] In the above steps, when the valve ball is being processed, the first movable component 401 and the second movable component 402 are both waiting in the loading or unloading waiting position, so as to quickly transfer after the processing is completed, achieve the best transfer speed, realize continuous processing, and ensure that each processing platform is in working state at the same time, which is conducive to improving work efficiency.

[0093] In the step (S102), the first gripper 4012 vertically grasps the ball blank 100, and before loading it at the first processing platform 301, the ball blank 100 is rotated to a horizontal direction for loading. The clamping assembly 3013 is clamped on the outer surface of the ball blank 100 so that the two channel openings of the main channel 102 are placed in a horizontal direction, that is, along the Y-axis direction, to facilitate the first tool assembly 3012 to be inserted into the main channel 102.

[0094] In the above step (S103), the first tool assembly 3012 fits tightly against the inner surface of the ball blank 100, and through axial and radial movements, the first tool assembly 3012 fits against the inner surface of the ball blank 100 to gradually grind the inner wall 103 of the ball blank 100, so as to ensure that every part of the inner wall 103 is ground and the processing quality is guaranteed.

[0095] In the step (S104), after the second gripper 4013 vertically transfers the first semi-finished valve ball 100A along the X-axis direction to the second loading position 3021 of the second processing platform 302, the second gripper 4013 is rotated under the action of the rotating element 4014 and the second processing drive assembly 502, so that the first semi-finished valve ball 100A changes from vertical to horizontal, and is then able to be sleeved on the outer side of the support shaft 3023 along the Y-axis direction to be supported and clamped, and rotated by the support shaft 3023.

[0096] It is worth mentioning that the outer surface of the ball blank 100 also has an edge line 107, that is, the outer wall 104 of the ball blank 100 is not a smooth arc shape. When the outer wall 104 is processed, the edge line 107 also needs to be processed to make the outer wall 104 become a smooth arc structure. In this way, when the finished valve ball 100D is used, it is easier to rotate under the action of the valve stem, and the connection mode of the channel can be changed with a smaller torque, thereby changing the flow direction of the medium.

[0097] In the step (S105), the second tool assembly 3022 can rotate under the driving action of the second machining drive assembly 502, and the chamfering assembly 3024 moves along the direction of the second axis and the first axis, that is, along the Y-axis and X-axis directions, under the driving action of the second machining drive assembly 502, so as to be used for chamfering processing on both sides of the main channel opening and removing burrs generated during the chamfering process.

[0098] In the process of processing the outer wall 104 of the ball blank 100, the second tool assembly 3022 and the chamfering assembly 3024 can process the outer wall in the original rust state on the one hand, and grind the edge line 107 on the other hand, so that the entire outer wall is in a smooth arc shape. In the processing process, the support shaft 3023 can be rotated according to the preset parameters, the second tool assembly 3022 performs rotary cutting, and the chamfering assembly 3024 can also move forward and backward and left and right to grind the burrs produced by the cutting of the second tool assembly 3022, so that the outer wall of the ball blank 100 becomes smooth by gradually cutting and grinding to meet the production requirements.

[0099] The support shaft 3023 can be implemented as a Hankun spindle head, the chamfering assembly 3024 can be implemented as a chamfering slide, and the second tool assembly 3022 can be implemented as a rotating tool.

[0100] In the above steps, the three grippers can move vertically and horizontally along the frame 305 under the action of the mobile drive device 600, that is, move in the Z-axis, X-axis and Y-axis directions, so as to clamp the valve ball of each processing platform for transportation, and can move in a circular motion to ensure that each processing platform operates at the same time and improve production efficiency.

[0101] In addition, in the above steps, when the first moving component 401 moves to the second loading position 3021 to complete loading, the first moving component 401 returns to the first processing platform 301 to pick up and load materials, and then transfers the products processed by the first processing platform 301 to the second processing platform 302 again. At the same time, the products processed by the second processing platform 302 are transferred to the third processing platform 303 by the second moving component 402, and the operation is cyclically performed in sequence to ensure that each processing platform can operate at the same time. This cyclic mode significantly improves production efficiency.

[0102] In the present invention, the fully automated processing procedure can not only ensure the uniformity of product specifications and improve product quality, but also improve production efficiency, so that the time for processing a valve ball is greatly shortened, which is of great significance for industrial mass production.

[0103] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
