Description

Technical Field

[0001] The invention relates to the technical field of valve ball production and manufacturing, and in particular to a spherical valve component grooving and polishing device. Background Art

[0002] Ball valves usually use a sphere with a circular channel as the opening and closing element. The sphere is a valve that opens and closes as the valve body rotates. The opening and closing element of a ball valve is a valve ball with a through hole in the main body and a groove on the outer wall. It rotates around an axis perpendicular to the channel to open and close the channel and change the flow direction of the medium. Ball valves have been widely used in petroleum, chemical industry, power generation, water heating, water conservancy, shipbuilding, papermaking, atomic energy, aviation, rockets and other fields because of their advantages such as small fluid resistance, simple structure, tight and reliable, easy operation, fast opening and closing, and wide application range.

[0003] During the valve ball manufacturing process, it is necessary to groove the outer wall of the valve ball to form an outer groove that is independent of the through hole. When installed in the ball seat, the outer groove and the through hole are connected to different pipes respectively through the rotation of the ball rod, forming different medium channels, thereby achieving the need to change the flow direction of the medium.

[0004] In the current equipment for producing valve balls, it is necessary to use a slotting machine to make the outer groove first. However, for valve balls made of stainless steel, burrs will be generated at the edge of the slotting position after slotting, and then the burrs must be removed to obtain a finished product with a smooth exterior. At present, one method is to remove the burrs manually, which is inefficient and has high labor costs. In addition, due to the different technical levels of workers and differences in operating methods, the quality of the finished products is not uniform. On the other hand, the entire valve ball is placed in a machine and the burrs are removed by blind punching through rotary grinding. During the blind punching process, there is no target, and the outer wall of the entire valve ball will be rubbed, which will damage the position without burrs, resulting in defective products, and thus making the product yield low. In addition, after blind punching, the entire valve ball needs to be re-polished and cleaned, which has many processes, takes a long time, is costly, and is not environmentally friendly, and cannot meet the needs of industrial production.

Therefore, the deburring position is the position where the burr is generated. The positioning is accurate, which can ensure the quality of the product and improve the product yield.

[0008] Another advantage of the present invention is that it provides a spherical valve component grooving and grinding device. According to another embodiment, after grooving at a grooving position, deburring can be performed directly at the grooving position.

[0051] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0052] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0053] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0054] Stainless steel spherical valve parts need to form a groove on the outer wall before they can be used in industrial production. However, due to the hardness of stainless steel, burrs will be generated in the process of forming the groove. The burr is generated on one side of the groove. If the positioning is inaccurate, other parts of the outer wall of the sphere will be ground off during the grinding process. In addition, different spheres have different damage locations and degrees, resulting in inaccurate sphere sizes and inability to be used. The independent operations of outer grooving and deburring used in the current production process not only have low production efficiency, but also low yield rate. The specifications of the produced spheres are not uniform and cannot meet application requirements.

[0055] The present invention provides a spherical valve component grooving and grinding device for automatically processing a spherical raw material to form a spherical valve component to be used in a ball valve. For example, but not limited to, grooving and grinding processing are performed. A spherical raw material 10 needs to have a groove opened in the outer wall so that it can be used as an opening and closing element in a ball valve. Different channels can be opened by rotation to change the flow direction of the medium to meet production application requirements. In the current production process, it is necessary to open a groove of a predetermined size and shape on the outer wall of the spherical raw material 10 before it can be used. For spherical raw materials made of stainless steel, burrs will be generated after the outer wall is grooved, and manual deburring is required, resulting in low product yield, low production efficiency, and high production cost. The present embodiment combines grooving and deburring into one, and performs grooving and deburring in a fully automated manner.

[0056] Reference Fig.11AAs shown, the ball material 10 includes a ball body 11 and a through hole 12, two orifices 13, an outer surface 14 and an inner surface 15. The through hole 12 passes through both ends of the ball body 11. The orifices 13 are arranged at both ends of the through hole 12 and are connected to the through hole 12 to form a channel for the flow of the medium during the application process. The outer surface 14 is arranged on the outside of the ball body 11, and the inner surface 15 is arranged inside the ball body 11 and surrounded by the outside of the through hole 12, wherein the surfaces of the outer surface 14 and the inner surface 15 are smooth to adapt to the flow of different media.

[0057] However, the ball material 10 has only one through hole 12, and the medium flow cannot be changed in multiple directions during application, which cannot meet the actual application requirements. In actual use, multiple channels need to be formed, so it is necessary to groove the outer wall of the ball material 10. After the grooves are grooved, when it is installed on a ball seat, the grooves formed on the outer wall due to the grooves and the through hole 12 inside can connect different channels, and then the medium flow direction can be easily changed by rotating the valve stem during application.

[0058] Reference Figure 1 To Attachment Fig. 11B As shown, a spherical valve component grooving and grinding device according to a preferred embodiment of the present invention is schematically shown. The spherical valve component grooving and grinding device provided by the present invention can groove the outer wall of the spherical raw material 10, and can grind the burrs generated by the grooves at the same time, integrating the grooving and deburring in one, which not only improves the production efficiency, but also can ensure the accuracy of the deburring, will not damage the outer surface of the spherical raw material 10, and can produce finished products with uniform specifications.

[0059] Reference Figure 1 To Attachment Figure 7 As shown, in this embodiment, the spherical valve component grooving and grinding device includes a manipulator 20, a positioning assembly 30, a grooving assembly 40, a deburring assembly 50, an operating table 60, and a device body 70, wherein the manipulator 20, the positioning assembly 30, the grooving assembly 40, the deburring assembly 50 and the operating table 60 are all installed on the device body 70, and the various components cooperate with each other to process the spherical raw material 10.

[0060] The spherical valve component grooving and grinding device further comprises a raw material storage area 80 and a finished product storage area 90, wherein the raw material storage area 80 and the finished product storage area 90 are respectively arranged on both sides of the device body 70 to store the spherical raw material 10 and the spherical valve component 100 respectively.

[0061] That is to say, the spherical raw material 10 is placed in the raw material storage area 80, grabbed by the manipulator 20, and positioned by the positioning component 30, and then grooved by the groove component 40, and then the deburring component 50 grinds the burrs generated by the grooves. The finished product after grinding is the spherical valve component 100, and the spherical valve component 100 is transported to the finished product storage area 90, wherein the operating table 60 is used to set various process parameters for processing to produce the spherical valve component 100 that meets the application requirements.

[0062] Reference Figure 3 As shown, the manipulator 20 includes a frame 21, a gripping portion 22, a guide rail 23, a connecting belt 24 and a first driving element 25, wherein the guide rail 23 is disposed at the top of the device body 70, the frame 21 is connected to the guide rail 23 and the connecting belt 24, the first driving element 25 is connected to the frame 21 and the connecting belt 24, and the gripping portion 22 is disposed at the end of the frame 21. Under the driving cooperation of the driving element 25 and the connecting belt 24, the frame 21 can move left and right, up and down, and forward and backward along the guide rail 23, that is, horizontal movement in the left and right and forward and backward directions and vertical movement in the up and down directions, so as to transport the ball raw material 10 from the raw material storage area 80 to the positioning assembly 30, so as to facilitate subsequent positioning for grooving and deburring.

[0063] One end of the frame 21 is arranged on the top of the device body 70, and extends through the top of the device body 70 to the inside of the device body 70, so that the grasping part 22 is located inside the device body 70, and under the action of the first driving element 25, the frame 21 can move along the device body 70 to better grasp the spherical raw material 10 for transportation, loading and positioning.

[0064] The grabbing part 22 can be opened and closed under the action of the first driving element 25, so as to better and accurately grab the spherical raw material 10 in a preset manner. In this embodiment, the grabbing part 22 grabs the spherical raw material 10 horizontally, and then transports it to the slotting assembly 40 for loading, and the spherical raw material 10 is loaded according to the horizontal direction of the grabbing, that is, the spherical raw material 10 is fixed through the orifice 13 and the through hole 12, so as to facilitate slotting from the outer surface 14 of the spherical raw material 10.

[0065] Reference Figure 4 As shown, the slotting assembly 40 includes a loading portion 41 , and the loading portion 41 is disposed on the device body 70 to receive the ball raw material 10 transferred by the robot 20 .

[0066] Reference Figure 3 To Attachment Figure 5B As shown, the positioning component 30 includes a supporting element 31, and the size of the head end of the supporting element 31 matches the through hole 12 of the spherical raw material 10, so that after the robot 20 transfers the spherical raw material 10 to the loading part 41, it is supported by the supporting element 31, that is, the head end of the supporting element 31 extends into the through hole 12 of the spherical raw material 10, so that the spherical raw material 10 is received by the supporting element 31 and sleeved on the outside of the supporting element 31, and then supported and fixed by the supporting element 31.

[0067] The positioning assembly 30 also includes a moving element 32 and a third driving element 33. The moving element 32 is connected to the supporting element 31. The third driving element 33 is connected to the moving element 32 and drives the moving element 32 to move. During the movement of the moving element 32, the supporting element 31 is driven to move left and right and forward and backward, that is, to move along the directions of the X-axis and the Y-axis, so as to drive the spherical material 10 sleeved on the supporting element 31 to move accordingly, so as to fix the spherical material 10 to a subsequent first processing position and a second processing position. The first processing position is to remove the spherical material 10. The burr position, the second processing position is the slotting position, under the action of the third driving element 33 driving the moving element 32, the moving element 32 drives the supporting element 31 to switch between the loading position, the first processing position and the second processing position to perform loading, deburring and slotting operations, wherein the spherical raw material 10 is not flipped during the movement between the first processing position and the second processing position, but moves along the X-axis direction while being clamped and fixed, so that the deburring component 50 can accurately grind at the position where the burr is generated to ensure the accuracy of slotting and deburring.

[0068] It is worth mentioning that the present invention defines the first axis as the X-axis direction, that is, the left-right direction, defines the second axis as the Y-axis direction, that is, the front-back direction, and defines the third axis as the Z-axis direction, that is, the vertical direction. The movement along the first axis (X-axis) direction is the left-right movement in the horizontal direction, the movement along the second axis (Y-axis) direction is the front-back movement in the horizontal direction, and the movement along the third axis (Z-axis) direction is the up-and-down movement in the vertical direction.

[0069] The moving element 32 and the third driving element 33 can be implemented as a Hankun slide.

[0070] The slotting component 40 also includes a fixing portion 42, which is arranged on the loading portion 41. The size of the fixing portion 42 matches the size of the spherical raw material 10. When the spherical raw material 10 is transported to the loading portion 41 by the robot 20, it is received by the supporting element 31, and then the moving element 32 moves under the drive of the third driving element 33, driving the supporting element 31 to move toward the fixing portion 42, so that the spherical raw material 10 can be clamped and fixed between the positioning component 30 and the fixing portion 42.

[0071] The slotting assembly 40 further includes a slotting tool 43, a rotating shaft 44 and a second driving element 45. The rotating shaft 44 is connected to the second driving element 45, and the slotting tool 43 is connected to the end of the rotating shaft 44. Under the drive of the second driving element 45, the rotating shaft 44 is suitable for rotating, thereby driving the slotting tool 43 to cut and slot the spherical raw material 10.

[0072] Specifically, the robot 20 transfers the spherical raw material 10 to the loading part 41. After the spherical raw material 10 is clamped and fixed by the supporting element 31 and the fixing part 42, the moving element 32 drives the spherical raw material 10 to move along the X-axis direction, that is, toward the direction of the slotting tool 43, under the drive of the third driving element 33, until the spherical raw material 10 moves to the second processing position of the preset position according to the preset data, and the second driving element 45 drives the rotating shaft 44 to rotate, so that the slotting tool 43 cuts and slots the outer wall of the spherical raw material 10 at the second processing position.

[0073] It is worth mentioning that the slotting tool 43 is a toothed tool, and a plurality of toothed tools are arranged in a circle at intervals, that is, a plurality of toothed tools are arranged in a ring around the rotating shaft 44, arranged with the rotating shaft as the center, and rotate accordingly with the rotation of the rotating shaft, so as to achieve the purpose of slotting while rotating. When rotating to different positions, different tools contact the outer wall of the spherical raw material, so as to be able to cut step by step or in stages.

[0074] For example, first, the first tool is brought into contact with the outer wall of the spherical material 10 to cut off a small part of the outer wall, and then the third driving element 33 drives the moving element 32 to drive the spherical material 10 to move horizontally, that is, to move in the direction of the slotting tool 43, and at the same time, the rotating shaft 44 rotates, driving the slotting tool 43 to rotate so that the next tool contacts the outer surface 14 of the spherical material, further cutting is performed on the basis of the previous cutting step, and then the rotation is continued, and so on, so that more and more material is cut off, and the size of the milled groove becomes larger and larger until it meets the requirements.

[0075] Since the stainless steel ball is relatively hard, the present invention uses multiple cutters to cut gradually. Different cutters are rotated to correspond to the ball material at different times, thereby achieving the purpose of gradual cutting. On the one hand, it can reduce the wear of the cutter, and on the other hand, it can make the specifications of the grooves meet the application requirements, and different cutters can be replaced according to the application requirements to cut out external grooves that meet the required dimensions.

[0076] It is worth mentioning that Fig. 11B The figure shows a schematic diagram of the process of forming a product after slotting in an embodiment of the present invention. In this embodiment, the attached Fig.11A The spherical raw material 10 shown is processed so that an outer groove 16 is formed after the spherical raw material 10 is grooved. The outer groove 16 has a groove 160 and two end walls 161, two side walls 162 and a bottom wall 163. The end walls 161, the side walls 162 and the bottom wall 163 are formed around the groove 160. The shape of the groove cutting tool 43 matches the outer groove 16, and has a front face, a side face and an end face, so that the structural shape of the outer groove 16 can be ground at a preset position on the outer surface of the spherical raw material 10.

[0077] In the actual production process, when the outer groove 16 is formed, burrs 170 are generated at the edge of the bottom of the outer groove 16. Fig. 11B As shown, since the position of the generated burr is fixed, the deburring assembly 50 can be directly started to grind the burr 170 without damaging other parts.

[0078] In addition, those skilled in the art will appreciate that toothed cutters of different sizes and thicknesses may also be used. Fig.10 As shown, the grooving tool 43B has a plurality of toothed tools 430B of different sizes, and the toothed tools 430B are arranged from small to large with the rotating axis as the center. As the rotating axis rotates, the toothed tools 430B cut the outer surface 14 of the spherical raw material 10 in sequence from small to large sizes, thereby achieving the purpose of gradual cutting.

[0079] Specifically, during the rotational cutting process of the toothed cutter 430B, the cutters from small to large sizes gradually contact the spherical raw material 10 in sequence, and then gradually cut from small to large sizes. In this way, during the cutting process, the third driving element 33 does not need to move the spherical raw material 10 toward the slotting cutter 43B after each cutter finishes cutting. In this variant implementation, the spherical raw material 10 can be fixed, and the rotating shaft 44 only needs to rotate to make different cutters correspond to the positions to be cut, thereby achieving the purpose of gradual cutting and slotting through cutting.

[0080] When the robot 20 moves to the loading part 41, the grabbing part 22 opens, the supporting element 31 catches the spherical raw material 10, and then the grabbing part 22 is driven by the first driving element 25 to return to the material picking position and wait for re-picking. Such a cycle is beneficial to improving production efficiency.

[0081] In this embodiment, the deburring assembly 50 includes a deburring element 51, a connecting body 52, a fourth driving element 53 and a fifth driving element 54, wherein the deburring element 51 is connected to the connecting body 52, and the fourth driving element 53 and the fifth driving element 54 are both connected to the connecting body 52. ​​Driven by the fourth driving element 53 and the fifth driving element 54, the deburring element 51 is able to move vertically and horizontally, and can then align the burr position for grinding. The fourth driving element 53 is vertically connected to the deburring element 51 to control the movement of the deburring element 51 along the second axis Y axis, and the fifth driving element 54 is perpendicular to the fourth driving element 53 to control the movement of the deburring element 51 along the third axis Z axis.

[0082] Specifically, after the slotting is completed, the moving element 32 carries the spherical material 10 back to the first processing position. After reaching the preset position, the deburring element 51 is activated, the fourth driving element 53 is extended to the position, and drives the deburring element 51 to move forward to the first processing position. The fifth driving element 54 is extended to the position again, and drives the deburring element 51 to move downward to the first processing position. At this time, under the drive of the fourth driving element 53 and the fifth driving element 54, the deburring element 51 has been aligned with the burr position of the spherical material 10, and the fourth driving element 53 drives the deburring element 51 to move until the burr 170 is polished away. Then the fifth driving element 54 drives the deburring element 51 to retreat upward along the direction of the third axis Z axis, and the fourth driving element 53 drives the deburring element 51 to retreat backward along the direction of the second axis Y axis at the same time, waiting for the next grinding. Then, the moving element 32 retreats to its original position under the action of the third driving element 33 , and the supporting element 31 retracts to wait for the next loading. The processed spherical valve member 100 is transported to the finished product storage area 90 .

[0083] The fourth drive element 53 and the fifth drive element 54 may be implemented as pneumatic cylinders or electric cylinders.

[0084] In the present invention, the spherical valve component grooving and grinding method (S100) comprises the following steps:

[0085] (S10) The spherical raw material 10 is grabbed by the robot 20 and transported to the loading part;

[0086] (S20) The positioning assembly 30 receives and fixes the spherical material 10;

[0087] (S30) The ball raw material 10 is transported to a second processing position, and the slotting assembly 40 starts to rotate to cut and slot the fixed ball raw material 10 at the second processing position;

[0088] (S40) After slotting, the ball raw material 10 is transported to a first processing position, and the deburring assembly 50 moves to the first processing position to grind the burrs 170 generated by slotting at the first processing position.

[0089] In the step (S10), after the spherical material 10 is transported to the loading part 41, the manipulator 20 returns to the loading waiting point and continues to grab another spherical material, and the operation is cyclic. That is, while the spherical material 10 is being cut, the manipulator 20 returns to grab another spherical material, and after the cutting and grinding are completed, the manipulator 20 continues to load another spherical material, so as to achieve the purpose of continuous processing.

[0090] In the step (S20), the positioning component 30 positions the spherical raw material 10 to the loading position, the first processing position and the second processing position by moving along the first axis and the second axis, and after deburring in the step (S40), it returns to the loading waiting point for the next loading.

[0091] It is worth mentioning that, during the process of grooving the spherical material 10, the positioning assembly 30 transports the spherical material 10 to fit with the grooving tool 43 through horizontal movement, so that different tools can perform cutting to achieve step-by-step cutting.

[0092] In the step (S30), the slotting assembly 40 cuts the outer surface 14 of the sphere step by step by rotating, wherein the cutter of the slotting assembly 40 is tooth-shaped, and different cutters are aligned with the position to be cut of the sphere material by rotating.

[0093] In the step (S40), the deburring assembly 50 performs dual motion in vertical and horizontal directions so that the deburring element is aligned with the burr position generated after the slotting for grinding.

[0094] According to another embodiment of the present invention, the first processing position is pre-set by the control console 60, so that the deburring assembly 50 can grind the burrs only by moving up and down along the direction of the third axis Z axis.

[0095] In the present invention, various processing parameters can be pre-set through the control console 60, so that the robot 20, the positioning assembly 30, the grooving assembly 40 and the deburring assembly 50 can move and process according to the preset program parameters, thereby processing the spherical valve component 100 of uniform specifications to meet the application requirements of the ball valve.

[0096] In addition, under the conception of the present invention, those skilled in the art can understand that the spherical material 10 can also be fixed in one position, that is, the first processing position and the second processing position in the above embodiment are combined into one position, a slotting component is set on the side of the spherical material, and a deburring component is set directly above the spherical material, so that the slotting component can be moved horizontally toward the position where the spherical material is fixed to slot, and after slotting, the slotting component retreats, and the deburring component grinds the burrs generated by the slotting vertically downward, that is, slotting and grinding can be achieved at the same position, and the positioning accuracy can also be guaranteed. For details, refer to the second embodiment of the present invention.

[0097] Reference Figure 8 and attached Fig. 9 The structure diagram of the spherical valve member grooving and grinding device according to the second embodiment of the present invention is shown, which improves and deforms the driving aspects of the deburring assembly 50 and the grooving assembly 40 in the above embodiment. In this embodiment, a deburring assembly 50A includes a deburring element 51A, a deburring driving element 52A and an energy supply element 55A, and the deburring driving element 52A is connected to the deburring element 51A and the energy supply element 55A to drive the deburring element 51A to move vertically, so that the deburring element 51A can align with the burrs generated after the spherical material is grooved and grind the burr position.

[0098] That is to say, in this embodiment, when setting the program parameters through the control console, the slotting component 40 can move in the horizontal direction, and can be away from the spherical material after slotting, so that the deburring element 51A is directly above the slotting position, that is, slotting and deburring are in the same position. Since the sizes of the spherical materials 10 are the same, the sizes and speeds of the tools used for slotting are the same, and the slotting positions and slotting sizes of the spherical materials 10 are the same, then the burr positions, shapes and sizes of the burrs generated are the same. When the deburring element 51A is directly above the slotting position, when the deburring element 51A is driven by the deburring drive element 52A, after the deburring element 51A moves downward, it is directly aligned with the burr position for grinding.

[0099] The deburring drive element 52A may be implemented as a pneumatic cylinder or an electric cylinder.

[0100] 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.
