Description

Technical Field

[0001] The present invention relates to the technical field of ball processing equipment, and in particular to a high-efficiency ball stripping machine and a processing technology for ball valve ball cores. Background Art

[0002] Currently, the processing of the ball core within a ball valve typically requires multiple steps, gradually transforming the cylindrical pipe into the ball core. Existing processing techniques typically utilize multiple machines for each process, such as drilling the inner hole, turning the outer diameter, and creating the groove, all performed by separate machines.

[0003] This traditional processing method has many defects:

[0004] 1. High labor costs. Since each device requires at least one operator, the manpower investment is large and the cost remains high.

[0005] 2. It occupies a large area and requires the layout of at least three devices, which requires a large amount of production space and has a high purchase cost for each device.

[0006] 3. Low processing precision. Since manual labor is required to move materials between different equipment for loading and unloading, it is difficult to ensure the accuracy of the loading position each time, resulting in uneven product quality.

[0007] 4. Low production efficiency. Multiple devices operate independently and rely on manual labor to move materials. There is waiting time for process connection. At the same time, manual operation efficiency is limited, making it difficult to achieve continuous and efficient production. The overall processing cycle is long and cannot meet the rapid delivery needs of large-volume orders.

[0008] 5. The spindle speed of existing turning equipment is low, which makes it difficult to drive the material to rotate at high speed. As a result, it is difficult to accurately control the cutting force and accuracy when the turning equipment performs external cylindrical operations on the material. Due to insufficient speed, the flatness of the material surface after turning is poor. Even with the use of fine turning tools, it is impossible to effectively eliminate the surface processing marks and it is difficult to form a mirror effect. In addition, the low speed processing efficiency is low and cannot meet the high-precision and high-quality production requirements.

[0009] 6. In traditional external cylindrical turning operations, multiple devices are required to complete multiple processes in stages: first, the material is turned into a spherical shape by one device, and then the surface is polished by another device to achieve a mirror effect. This model not only requires frequent equipment changes, inconvenient operation, long processing cycles, and low production efficiency, but also positioning errors are prone to occur when the material is transferred between devices, which directly affects the turning accuracy and surface quality. Summary of the Invention

[0010] The purpose of this technical solution is to provide an efficient ball stripping machine and a processing technology for ball valve cores. By integrating multiple processing steps such as drilling inner holes, turning outer circles, and grooving, and realizing sequential loading and unloading through a material transfer device, the material can be accurately and continuously processed between different processes, thereby improving the problems of high labor costs, large equipment footprint, low processing accuracy, and low production efficiency in the processing of ball valve cores.

[0011] The purpose of this technical solution is achieved in this way:

[0012] A high-efficiency ball stripping machine comprises: a frame; a material moving device, which is installed on the frame and is used to transport materials to a set position; a reference setting device, which is installed on the frame and is used to cut the center hole and the lower half of the material transported by the material moving device; a turning device, which is installed on the frame and is located beside the reference setting device, and is used to turn the material transported from the reference setting device to form a spherical structure of the material; a milling device, which is installed on the frame and is located beside the turning device, and is used to mill the side walls of the material transported from the turning device to form grooves on the side walls of the material; the material is sequentially loaded to the reference setting device through the material moving device, moved to the turning device and the milling device, and finally unloaded from the milling device.

[0013] The above technical solution integrates core processes such as drilling the inner hole, turning the outer circle, and grooving of the ball valve core. It works in coordination through the datum setting device, turning device, and milling device on the frame, and the material transfer device completes automatic loading and unloading between processes, reducing manpower input and site occupancy, improving product quality consistency, and realizing efficient, continuous, and precise processing of the ball valve core, effectively ensuring the dual improvement of production efficiency and quality.

[0014] Preferably, the material moving device includes several clamping mechanisms that can move horizontally and vertically on the frame; the clamping assembly of the clamping mechanism has a clamping position for clamping the material; the datum setting device includes a datum setting clamping mechanism and a cutting mechanism, and the datum setting clamping mechanism has a datum setting clamping position; the turning device includes a turning clamping mechanism and a turning mechanism, and the turning clamping mechanism has a turning clamping position; the milling device includes a milling clamping mechanism and a milling mechanism, and the milling clamping mechanism has a milling clamping position; the center of the clamping position is coplanar with the vertical plane where the centers of the datum setting clamping position, the turning clamping position and the milling clamping position are located.

[0015] The above technical solution is designed so that the vertical planes where the center of the clamping position and the corresponding centers of the fixed reference clamping position, the turning clamping position and the milling clamping position are coplanar, so that the material in the clamping position can be moved and placed in the corresponding clamping position, thereby improving the accuracy of the material transported by the material transfer device and ensuring the position accuracy of the material when it is moved to different processing stations, thereby ensuring the accurate and continuous processing of the material between different processes.

[0016] Preferably, several clamping mechanisms are respectively installed above the corresponding fixed reference clamping position, turning clamping position and milling clamping position; the fixed reference clamping mechanism is horizontally installed on the frame, the cutting mechanism is vertically installed on the frame, and the cutting mechanism is located below the fixed reference clamping position; the turning mechanism is horizontally installed on the frame and is located beside the fixed reference clamping mechanism, the turning clamping mechanism is vertically installed on the frame and is located beside the cutting mechanism, and the turning mechanism is located at the rear side of the turning clamping position; the milling clamping mechanism is horizontally installed on the frame and is located beside the turning mechanism, the milling mechanism is vertically installed on the frame and is located beside the turning clamping mechanism, and the milling mechanism is located in front of the milling clamping position.

[0017] The above technical solution installs the clamping mechanism above the corresponding fixed reference clamping position, turning clamping position and milling clamping position, installs the fixed reference clamping mechanism, turning mechanism and milling clamping mechanism horizontally on the frame in sequence, and installs the cutting mechanism, turning clamping mechanism and milling mechanism vertically on the frame in sequence, thereby improving space utilization, increasing the compactness of the installation position of each mechanism, reducing the overall volume, and reducing the space and site occupied.

[0018] Preferably, the cutting mechanism of the reference setting device includes: a cutting assembly, which is slidably arranged on the frame and is used for cutting the material in the reference clamping position of the reference setting device; a cutting moving assembly, which is installed between the frame and the cutting assembly and is used to drive the cutting assembly to slide longitudinally on the frame; the cutting assembly includes a cutting tool, and the cutting tool includes a reaming portion and a plurality of arc portions, and the plurality of arc portions are circumferentially distributed in the lower half of the reaming portion, and the front end of the reaming portion has a reaming blade, and the reaming portion extends into the center hole of the material, and the reaming blade reams the center hole of the material, and the arc portion has an arc blade, and the arc blade cuts the lower end edge of the center hole of the material and the lower end outer wall of the material.

[0019] The cutting tool of the above technical solution includes a reaming part and several arc-shaped parts. The reaming part extends into the center hole of the material. The reaming blade of the reaming part reams the center hole of the material, and the arc-shaped blade cuts the lower edge of the center hole of the material and the lower outer wall of the material. By using the same cutting tool to achieve multiple cutting functions, it is only necessary to drive the cutting tool to rotate to complete multiple cutting processes of reaming, chamfering and milling the outer circle, thereby reducing cutting time, improving production efficiency and ensuring consistency in product processing.

[0020] Preferably, the turning mechanism of the turning device includes: a turning assembly, which is slidably mounted on the frame and is used to perform turning operations on the surface of the material in the turning clamping position of the turning device; a turning moving assembly 2, which is mounted between the frame and the turning assembly and is used to drive the turning assembly to approach or move away from the material in the turning clamping position of the turning device; the turning assembly includes: a swing driving member, which is mounted on the turning moving assembly 2; a swing arm, which is mounted on the driving end of the swing driving member; a turning tool holder, which is mounted on the swing end of the swing arm; a rough turning tool group, which is mounted on the turning tool holder; a fine turning tool, which is mounted on the turning tool holder, and the fine turning tool is located next to the rough turning tool group; the positions of the rough turning tool group and the fine turning tool are switched by the turning moving assembly 2, so that the rough turning tool group and the fine turning tool can perform turning operations on the material in the turning clamping position in turn; the turning clamping rotating assembly of the turning device includes a turning rotating spindle, and the turning rotating spindle is a 10,000-turn spindle.

[0021] The turning rotating spindle adopts a 10,000-rpm spindle, which drives the material to rotate at high speed through high speed, so that the turning component can accurately complete the external circle turning operation; the high speed ensures the turning accuracy of the material surface, and under the action of the fine turning tool, the material surface can achieve a mirror effect; at the same time, the rough turning and fine turning processing can be completed by swinging the swing arm up and down at a time, without the need for an additional fine turning processing mechanism, reducing the size of the machine and saving site space.

[0023] The above technical solution installs the rough turning tool one and the rough turning tool two on the same turning tool holder. The rough turning tool one and the rough turning tool two can turn the material surface in turn by only moving the turning tool holder up once. That is, the rough turning tool two turns the material for the first time, and then the rough turning tool one turns it again, so that the thickness of the material reaches the set thickness, and the material is turned twice. No additional turning mechanism is required to achieve multiple turning of the material, which saves turning time, improves production efficiency, reduces tool wear, and extends the service life of the rough turning tool.

[0025] The above technical solution not only performs the outer circle turning operation on the outside of the material, but also chamfers the upper and lower ends of the center hole of the material through the chamfering mechanism. There is no need to use multiple workstations for separate processing and production, which improves production efficiency, ensures efficient production of products, and reduces the space occupied by equipment.

[0026] Preferably, the turning clamping mechanism of the turning device includes: a turning clamping rotating assembly, which is slidably arranged on the frame, and a turning clamping position is provided on the turning clamping rotating assembly for clamping and rotating the material; a positioning assembly, which is installed on the side of the turning clamping rotating assembly, and the end of the positioning assembly extends into the turning clamping position for abutting the lower end of the material in the turning clamping position; a turning moving assembly 1, which is installed on the frame and connects the turning clamping rotating assembly and the positioning assembly, and is used to drive the turning clamping rotating assembly and the positioning assembly to slide longitudinally on the frame; the positioning assembly includes: a positioning frame, which is installed on the turning moving assembly 1; a positioning piece, which is installed on the positioning frame, and the front end of the positioning piece extends into the turning clamping position for abutting the lower end of the material to limit the longitudinal movement of the material on the turning clamping rotating assembly.

[0027] The above technical solution extends the front end of the positioning part into the turning clamping position, so that the positioning part rests on the lower end of the material, limiting the longitudinal movement of the material on the turning clamping rotating assembly, ensuring the accurate position of the material after loading, thereby ensuring the accuracy of the external cylindrical processing and the accuracy of each material processing.

[0028] Preferably, the high-efficiency ball stripping machine also includes: a drilling device, which is installed on the frame and located between the turning device and the milling device, and is used for drilling the side wall of the material transported by the turning device; the drilling device includes: a drilling clamping mechanism, which is installed on the frame, and the drilling clamping mechanism has a drilling clamping position for clamping the material processed by the turning device; the drilling mechanism is installed on the frame and is used for drilling the side wall of the material at the drilling clamping position; the drilling clamping mechanism includes: a support seat, which is installed on the frame, and the upper end of the support seat has the drilling clamping position; a pressing frame, which is installed on the side end of the support frame; a pressing piece, which is rotatably installed on the upper end of the pressing frame for pressing the material on the upper end of the support frame; a pressing driving piece, which is installed on the upper end of the pressing frame, and the driving end of the pressing driving piece is connected to the pressing piece, for driving the end of the pressing piece to be placed above or away from the drilling clamping position.

[0029] The above technical solution designs a drilling device to drill the side wall of the material, which meets the customer's additional production needs for the product and improves the applicability of the product. It does not require additional separate equipment for drilling operations and reduces space occupancy.

[0030] A process for processing a ball valve core, used in the above-mentioned high-efficiency ball stripping machine, comprises the following steps:

[0031] Step 1: The material transfer device loads the material to the reference setting device, the reference setting clamping mechanism of the reference setting device clamps the material, and the cutting mechanism cuts and expands the lower half of the material;

[0032] Step 2: The material moving device takes out the material in the fixed reference clamping mechanism and loads the material to the turning device. The positioning component of the turning device is against the lower end of the material, the turning clamping rotating component supports and clamps the material, the turning clamping rotating component rotates the material, and the lower chamfering tool is against the lower end of the material to perform chamfering operation on the material. The swing arm drives the turning tool holder to swing upward, so that the rough turning tool can turn the outer circle of the material. At the same time, the rough turning tool can turn the outer circle of the material again. The swing arm drives the turning tool holder to swing downward, and the fine turning tool polishes the outer wall of the material. When the swing arm drives the turning tool holder to swing downward to the set position, the turning tool holder makes the upper chamfering tool against the upper end of the material for chamfering operation;

[0033] Step 3: The material moving device takes out the material in the turning device and loads the material into the drilling device. The material is clamped by the drilling clamping mechanism, and the pressing member drives the pressing member to press the material on the upper end of the support seat. The drilling tool of the drilling mechanism drills the side wall of the material. When the drilling is completed, the pressing member drives the pressing member to leave the upper end of the material.

[0034] Step 4: The material transfer device takes out the material from the upper end of the support seat and loads the material into the milling device. The milling clamping mechanism clamps the material and moves the material toward the milling mechanism. The milling mechanism mills the side wall of the material by rotating the milling cutter. After milling is completed, the milling clamping mechanism moves the material to the bottom of the clamping position of the material transfer device.

[0035] Step 5: The material transfer device takes out the material in the milling clamping mechanism and unloads it.

[0036] Compared with the existing technology, this technical solution has the following outstanding and beneficial technical effects:

[0037] 1. This technical solution is designed to integrate multiple processing steps of ball valve core, such as drilling inner holes, turning outer circles, and grooving, etc., and the corresponding processing steps are processed through the corresponding reference device, turning device, and milling device on the frame. At the same time, a material transfer device is configured to realize the sequential loading and unloading of the corresponding processes, so as to realize the precise and continuous processing of materials between different processes, effectively reduce manpower input and site occupation, improve the consistency of product processing quality, improve the processing efficiency and quality of ball valve core, and ensure the demand for efficient production of ball valve core.

[0038] 2. The turning rotary spindle designed in this technical solution is a 10,000-rpm spindle. The high-speed turning rotary spindle drives the material to rotate at high speed, so that the turning component can accurately control the cutting process and improve the processing accuracy of the external circle turning operation; the high speed combined with the fine turning tool can quickly eliminate the processing marks on the surface of the material and make the surface as smooth as a mirror, which not only improves the appearance quality and performance of the product, but also shortens the processing cycle through high-speed and efficient processing mode, effectively improves production efficiency, and provides reliable guarantee for high-precision and high-quality ball valve ball core processing.

[0039] 3. The center of the clamping position designed in this technical solution is coplanar with the vertical plane where the center of the fixed reference clamping position, turning clamping position and milling clamping position are located, so that the material in the clamping position can be moved and placed in the corresponding clamping position, thereby improving the accuracy of the material transport by the material transfer device and ensuring the position accuracy of the material when it is moved to different processing stations, thereby ensuring the accurate and continuous processing of the material between different processes.

[0040] 4. The cutting tool designed in this technical solution includes a reaming portion and several arc-shaped portions. The reaming portion extends into the center hole of the material. The reaming blade of the reaming portion reams the center hole of the material. The arc-shaped portion has an arc-shaped blade. The arc-shaped blade cuts the lower edge of the center hole of the material and the lower outer wall of the material. By using the same cutting tool to realize multiple cutting processes, the cutting time is reduced, the production efficiency is improved, and the consistency of product processing is ensured.

[0041] 5. The turning device designed in this technical solution includes a turning mechanism and a chamfering mechanism. When turning the outer circle of the material, the upper and lower ends of the center hole of the material are chamfered by the chamfering mechanism at the same time. There is no need to use multiple workstations for separate processing and production, which improves production efficiency, ensures efficient production of products, and reduces the space occupied by equipment.

[0042] 6. This technical solution designs a drilling device to drill holes in the side walls of the material, meeting customers' additional production needs for the product and improving product applicability. It eliminates the need for additional separate equipment for drilling operations and reduces space occupancy.

[0043] 7. This technical solution is designed to install the clamping mechanism above the corresponding fixed reference clamping position, turning clamping position and milling clamping position, and to install the fixed reference clamping mechanism, turning mechanism and milling clamping mechanism horizontally on the frame in sequence, and to install the cutting mechanism, turning clamping mechanism and milling mechanism vertically on the frame in sequence, so as to improve space utilization, increase the compactness of the installation position of each mechanism, reduce the overall volume, and reduce the space and site occupied.

[0106] Step 1: The material moving device 2 loads the material 100 to the reference setting device 3, the reference setting clamping mechanism 31 of the reference setting device 3 clamps the material 100, and the cutting mechanism 32 cuts the lower half of the material 100 into a hemispherical shape and expands the center hole 101, so that the material is Figure 19 The D1 state in the process is processed into the D2 state;

[0107] Step 2: The material moving device 2 takes out the material 100 in the fixed reference clamping mechanism 31 and loads the material 100 to the turning device 4. The positioning component 46 of the turning device 4 is against the lower end of the material 100. The turning clamping rotating component 45 supports and clamps the material 100. The turning clamping rotating component 45 rotates the material 100. The lower chamfering tool 432 is against the lower end of the material 100 to chamfer the lower end opening edge of the center hole 101 of the material 100. The swing arm 482 drives the turning tool holder 483 to swing upward, so that the rough turning tool 4842 can turn the outer circle of the material 100. At the same time, the rough turning tool 4841 can turn the outer circle of the material 100 again, so that the material is Figure 19The D2 state in the process is processed into the D3 state; when the swing arm 482 drives the turning tool holder 483 to swing downward for resetting, the fine turning tool 485 polishes the outer wall of the material 100. When the swing arm 482 drives the turning tool holder 483 to swing downward to the set position, the turning tool holder 483 makes the upper chamfering tool 431 rest against the upper end of the material 100 and performs chamfering operation, so that the material is Figure 19 The D3 state in the process is processed into the D4 state;

[0108] Step 3: The material moving device 2 takes out the material 100 in the turning device 4 and loads the material into the drilling device 6. The material 100 is clamped by the drilling clamping mechanism 61. The pressing driving member 614 drives the pressing member 613 to press the material 100 on the upper end of the support seat 611. The drilling tool of the drilling mechanism 62 approaches and drills the side wall of the material 100, so that a through hole 103 is formed on the side wall of the material, thereby allowing the material to be removed from the material. Figure 19 The D4 state in the process is processed into the D5 state. When the drilling is completed, the pressing member 614 drives the pressing member 613 to leave the upper end of the material 100.

[0109] Step 4: The material moving device 2 takes out the material 100 on the upper end of the support seat 611 and loads the material 100 into the milling device 5. The milling clamping mechanism 51 clamps the material 100 and moves the material 100 toward the direction close to the milling mechanism 52. The milling mechanism 52 performs milling operation on the side wall of the material 100 by rotating the milling cutter 563, so that the material is Figure 19 The D5 state in the process is processed into the D6 state. After the milling is completed, the milling clamping mechanism 51 moves the material 100 to the bottom of the clamping position 24 of the material moving device 2;

[0110] Step 5: The material moving device 2 takes out the material 100 in the milling clamping mechanism 51 and unloads it.

[0111] Example 2:

[0112] The design scheme of this embodiment is basically the same as the design scheme of embodiment 1, with the difference being that: in order to meet different production needs, the drilling device 6 is optional. When there is no need to drill the material 100, the drilling device 6 may not be installed on the frame 1. The milling device 5 is installed on the frame 1 and is located next to the turning device 4, and is used to mill the side wall of the material 100 transported from the turning device 4; that is, the material transfer device 2 takes out the material 100 processed in the turning device 4 and loads the material 100 to the milling device 5.
