Description

Technical Field

[0001] The present invention relates to the technical field of valve body upper cover processing, and more specifically, to a thread processing mechanism of a valve body upper cover processing line. Background Art

[0002] The valve body is a main component in a valve. It serves as the housing for internal components such as the valve stem, valve disc, and valve seat, and is crucial for ensuring the correct operation and sealing of the valve. The valve body can adopt different mechanical manufacturing methods according to the pressure grade, such as casting and forging, to adapt to working environments with medium-low pressure or medium-high pressure. At the same time, the material of the valve body is also selected according to different process media to ensure its durability and sealing performance. A good seal needs to be formed between the upper cover of the valve body and the valve body itself to prevent medium leakage. Through processing, it can ensure that the fitting accuracy and surface roughness between the upper cover and the valve body meet the requirements, thereby achieving reliable sealing.

[0003] Among them, the patent with publication number CN106002275A discloses a thread processing mechanism of a valve body upper cover processing line. The thread processing mechanism of this valve body upper cover processing line includes a thread push-pull cylinder mounting plate. A thread push-pull cylinder is mounted on the upper plane of the thread push-pull cylinder mounting plate through a cylinder fixing seat. Two parallel thread linear guides are mounted at a position in front of the thread push-pull cylinder on the thread push-pull cylinder mounting plate. The thread linear guides are in the same movement direction as the thread push-pull cylinder, and a thread push-pull plate is mounted on the slider of the thread linear guide;

[0004] When this structure is in use, while the tapping lifting motor drives the lead screw nut fixing seat to make the tapping lifting plate slide downward, the tapping motor drives the rotary transmission component to make the first three-jaw connector and the second three-jaw connector rotate, and the drills on the first three-jaw connector and the second three-jaw connector drill holes in the valve body upper cover. However, when this structure is in use, it is difficult to achieve the coherence of workpiece drilling and positioning, resulting in low workpiece processing efficiency. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a thread processing mechanism of a valve body upper cover processing line, aiming to solve the problems proposed in the above background art.

[0006] The present invention provides the following technical solutions: A thread processing mechanism of a valve body upper cover processing line, including a base, and a linkage component is arranged on the base;

[0007] The linkage component includes a limit seat arranged on the base. A sliding rod is slidably connected to the middle of the limit seat. One end of the sliding rod is fixedly provided with a cushion plate, and a tapping machine for processing is arranged on the cushion plate;

[0008] A limiting shaft is provided on one side of the surface of the limiting seat. One end of the limiting shaft is installed with a limiting arc rod through a bolt. One end of the limiting arc rod is fixedly provided with a stopper for lifting the workpiece. The outer side of the limiting shaft is rotationally connected with a rotating sleeve. One side of the surface of the rotating sleeve is fixedly provided with a pressing plate. A limiting pin for limiting is inserted into the surface of the pressing plate. One side of the limiting pin is provided with a deflecting frame. The deflecting frame is rotationally connected with the pressing plate. The deflecting frame is provided with a contact angle extending to one side of the stopper. One side of the surface of the deflecting frame is provided with a spring. One end of the spring is hooked on the limiting seat. The side of the rotating sleeve away from the pressing plate is fixedly provided with an extension rod. One side of the surface of the limiting seat is rotationally connected with a side shaft. A deflecting disc is fixedly provided on the side shaft. The deflecting disc extends to the bottom of the extension rod. One side of the deflecting disc is provided with a separating disc. The separating disc is fixed on the side shaft. The separating disc is fixedly provided with a side extension cover in contact with the extension rod. One side of the separating disc away from the side extension cover is provided with a first gear. The first gear is fixed on the side shaft. The bottom of the first gear is provided with a driving motor installed on the base. The output end of the driving motor is provided with a second gear. The second gear is located at the bottom of the first gear and meshes with the first gear.

[0009] It can be seen that in the above technical solution, the workpiece is blocked by the stopper, and then the driving motor drives the second gear to rotate. When the second gear rotates, it drives the first gear to rotate. When the first gear rotates, it drives the side shaft to rotate, and then the deflecting disc, separating disc, limiting sleeve and arc-edge block on the side shaft rotate. When the deflecting disc rotates, it contacts the extension rod, and then the extension rod can rotate along the axis point of the connection between the rotating sleeve and the limiting shaft through the rotating sleeve, and then the pressing plate approaches the workpiece. When the pressing plate deflects, it can also drive the deflecting frame and the contact angle to displace, which is easy for the contact angle and the pressing plate to extend to the outside of the workpiece to position the workpiece, and then realize the function of clamping the workpiece, which is easy for the workpiece to be placed and ensures the stability when the workpiece is clamped.

[0010] Optionally, in a possible implementation manner, two limiting sleeves are sleeved on one end of the side shaft, and each of the limiting sleeves is installed on the side shaft through a bolt. Arc-edge blocks are installed on both of the limiting sleeves through bolts. A shaft pin seat is installed on one side of the surface of the limiting seat through a bolt. A deflecting plate is rotationally connected to the shaft pin seat. One end of the deflecting plate is provided with a sliding shaft. The sliding shaft is located between the two arc-edge blocks and contacts the arc-edge blocks. The end of the deflecting plate away from the sliding shaft is provided with a limiting ring. The middle of the limiting ring is provided with a contact ring. The contact ring is sleeved on the outside of the sliding rod. One side of the contact ring is provided with a shaft pin frame. The shaft pin frame is located on the sliding rod and is threadedly connected to the sliding rod. A plurality of hinge rods are hinged on the outside of the shaft pin frame, and one end of each of the hinge rods extends to one side of the contact ring;

[0011] It can be seen that in the above technical solution, the deflection frame deflects on the pressing plate, making it easy for the end of the pressing plate and the contact angle to contact the outside of the workpiece. When the side shaft rotates one circle, the side extension cover can press against the top of the extension rod, causing the extension rod, the rotating sleeve, and the pressing plate to rotate, and then enabling the contact angle and the pressing plate to separate from the workpiece, facilitating the removal of the workpiece. At the same time, when the side shaft rotates, it can also drive the limit sleeve and the arc-shaped block to rotate. When the arc-shaped block rotates, it rubs against the sliding shaft, causing the sliding shaft to push the deflection plate to rotate along the center point of the connection between the deflection plate and the pin seat, and then pushing the limit ring and the contact ring to displace outside the sliding rod. When the limit ring and the contact ring displace, they will contact the hinge rod, enabling the sliding rod to drive the cushion plate and the tapping machine to slide within the limit seat, allowing the tapping machine to perform the function of pressing and threading the workpiece, ensuring the processing efficiency. And through the rotation of the side shaft, while driving the pressing plate and the deflection frame to displace to clamp the workpiece, the deflection plate drives the limit ring to displace and contact the drive motor, driving the sliding rod and the tapping machine to press against the workpiece for processing, realizing the functions of positioning, processing, and continuous material taking of the device workpiece during processing, and improving the processing efficiency of the workpiece.

[0012] The technical effects and advantages of the present invention:

[0013] 1. When the turntable rotates in the present invention, it contacts the extension rod, causing the extension rod to rotate along the center point of the connection between the rotating sleeve and the limit shaft through the rotating sleeve, making the pressing plate approach the workpiece. And when the pressing plate deflects, it can also drive the deflection frame and the contact angle to displace, making it easy for the contact angle and the pressing plate to extend to the outside of the workpiece for workpiece positioning, and then realizing the function of clamping the workpiece, facilitating the placement of the workpiece and ensuring the stability when the workpiece is clamped;

[0014] 2. When the pressing plate and the deflection frame deflect in the present invention, it can also pull the spring to extend through the deflection frame, and make one end of the deflection frame contact the limit pin, making it easy for the deflection frame to deflect on the pressing plate, making it easy for the end of the pressing plate and the contact angle to contact the outside of the workpiece. When the side shaft rotates one circle, the side extension cover can press against the top of the extension rod, causing the extension rod, the rotating sleeve, and the pressing plate to rotate, and then enabling the contact angle and the pressing plate to separate from the workpiece, facilitating the removal of the workpiece;

[0015] 3. When the arc-shaped block rotates in the present invention, it rubs against the sliding shaft, causing the sliding shaft to push the deflection plate to rotate along the center point of the connection between the deflection plate and the pin seat, and then pushing the limit ring and the contact ring to displace outside the sliding rod. When the limit ring and the contact ring displace, they will contact the hinge rod, enabling the sliding rod to drive the cushion plate and the tapping machine to slide within the limit seat, allowing the tapping machine to perform the function of pressing and threading the workpiece, ensuring the processing efficiency;

[0016] In summary, through the corresponding cooperation of each structure, in the way of rotating around the side axis, while driving the displacement of the pressure plate and the deflection frame to clamp the workpiece, the deflection plate drives the displacement of the limit ring to contact the driving motor, driving the slide bar and the tapping machine to abut against the workpiece for processing the workpiece, realizing the functions of positioning, processing and material taking continuous operation of the device workpiece during processing, and improving the processing efficiency of the workpiece.

[0028] As shown in the Figures 1-8 thread processing mechanism of the valve body upper cover processing line shown, through the linkage assembly arranged on the base 1, through the corresponding cooperation of each structure, in the way of rotating the side shaft 16, while driving the pressing plate 10 and the deflection frame 12 to displace and clamp the workpiece, the deflection plate 26 drives the limit ring 28 to displace and contact the drive motor 21, driving the sliding rod 3 and the tapping machine 5 to abut against the workpiece to process the workpiece, realizing the functions of positioning, processing and material taking continuous operation of the device workpiece during processing, improving the workpiece processing efficiency, and the specific structure of the assembly is as follows;

On one side of the surface of the rotating sleeve 9, a pressing plate 10 is fixedly provided. A limit pin 11 for limiting is inserted on the surface of the pressing plate 10. On one side of the limit pin 11, a deflection frame 12 is provided. The deflection frame 12 is rotatably connected with the pressing plate 10. On the deflection frame 12, a contact angle 13 extending to one side of the stop block 8 is provided. On one side of the surface of the deflection frame 12, a spring 14 is provided. One end of the spring 14 is hooked on the limit seat 2. On the side of the rotating sleeve 9 away from the pressing plate 10, an extension rod 15 is fixedly provided. On one side of the surface of the limit seat 2, a side shaft 16 is rotatably connected. On the side shaft 16, a deflection disk 17 is fixedly provided. The deflection disk 17 extends to the bottom of the extension rod 15. On one side of the deflection disk 17, a partition disk 18 is provided. The partition disk 18 is fixed on the side shaft 16. On the partition disk 18, a side extension cover 19 in contact with the extension rod 15 is fixedly provided. On the side of the partition disk 18 away from the side extension cover 19, a first gear 20 is provided. The first gear 20 is fixed on the side shaft 16. At the bottom of the first gear 20, a driving motor 21 installed on the base 1 is provided. The output end of the driving motor 21 is provided with a second gear 22. The second gear 22 is located at the bottom of the first gear 20 and meshes with the first gear 20.

[0031] Two limit sleeves 23 are sleeved on one end of the side shaft 16, and each limit sleeve 23 is installed on the side shaft 16 through a bolt. On each of the two limit sleeves 23, an arc-edge block 24 is installed through a bolt. On one side of the surface of the limit seat 2, a shaft pin seat 25 is installed through a bolt. A deflection plate 26 is rotatably connected to the shaft pin seat 25. One end of the deflection plate 26 is provided with a sliding shaft 27. The sliding shaft 27 is located between the two arc-edge blocks 24 and is in contact with the arc-edge blocks 24. One end of the deflection plate 26 away from the sliding shaft 27 is provided with a limit ring 28. In the middle of the limit ring 28, a contact ring 29 is provided. The contact ring 29 is sleeved on the outer side of the sliding rod 3. On one side of the contact ring 29, a shaft pin bracket 30 is provided. The shaft pin bracket 30 is located on the sliding rod 3 and is threadedly connected to the sliding rod 3. A plurality of hinge rods 31 are hinged on the outer side of the shaft pin bracket 30, and one end of each hinge rod 31 extends to one side of the contact ring 29.

[0032] During use according to the above structure, the staff installs the device at a designated position. When processing the workpiece, the workpiece is placed on one side of the stop block 8, and the stop block 8 separates the workpiece. Then, the driving motor 21 drives the second gear 22 to rotate. When the second gear 22 rotates, it drives the first gear 20 to rotate. When the first gear 20 rotates, it drives the side shaft 16 to rotate, and then the deflection disk 17, partition disk 18, limit sleeve 23 and arc-edge block 24 on the side shaft 16 rotate;

[0033] When the deflection turntable 17 rotates, it contacts the extension rod 15, and then the extension rod 15 can rotate along the axis point of the connection between the rotating sleeve 9 and the limit shaft 6 through the rotating sleeve 9. Then the pressing plate 10 approaches the workpiece, and when the pressing plate 10 deflects, it can also drive the deflection frame 12 and the abutting angle 13 to displace. It is easy for the abutting angle 13 and the pressing plate 10 to extend to the outside of the workpiece to position the workpiece, and then the function of clamping the workpiece is realized. It is easy to place the workpiece and ensure the stability when the workpiece is clamped;

[0034] And when the pressing plate 10 and the deflection frame 12 deflect, it can also pull the spring 14 to extend through the deflection frame 12, and make one end of the deflection frame 12 abut against the limit pin 11. It is easy for the deflection frame 12 to deflect on the pressing plate 10, and it is easy for the end of the pressing plate 10 and the abutting angle 13 to abut against the outside of the workpiece. When the side shaft 16 rotates one circle, the side extension cover 19 can press against the top of the extension rod 15, and make the extension rod 15, the rotating sleeve 9 and the pressing plate 10 rotate. Then the abutting angle 13 and the pressing plate 10 can be separated from the workpiece, which is convenient for taking out the workpiece;

[0035] At the same time, when the side shaft 16 rotates, it can also drive the limit sleeve 23 and the arc-edge block 24 to rotate. When the arc-edge block 24 rotates, it rubs against the sliding shaft 27. Then the sliding shaft 27 pushes the deflection plate 26 to rotate along the axis point of the connection between the deflection plate 26 and the pin seat 25, and then pushes the limit ring 28 and the abutting ring 29 to displace on the outside of the sliding rod 3. When the limit ring 28 and the abutting ring 29 displace, they will contact the hinge rod 31. Then the sliding rod 3 can drive the cushion plate 4 and the tapping machine 5 to slide in the limit seat 2, so that the tapping machine 5 can perform the function of pressing and threading the workpiece, ensuring the processing efficiency;

[0036] And through the rotation of the side shaft 16, while driving the pressing plate 10 and the deflection frame 12 to displace to clamp the workpiece, the deflection plate 26 drives the limit ring 28 to displace and contact the drive motor 21 to drive the sliding rod 3 and the tapping machine 5 to abut against the workpiece for processing the workpiece, realizing the function of continuous operation of positioning, processing and material taking of the device workpiece during processing, and improving the processing efficiency of the workpiece.

[0037] Different from the prior art, the present application discloses a threading processing mechanism of a valve body upper cover processing line. Through the corresponding cooperation of each structure, by rotating the side shaft 16, while driving the pressing plate 10 and the deflection frame 12 to displace to clamp the workpiece, the deflection plate 26 drives the limit ring 28 to displace and contact the drive motor 21 to drive the sliding rod 3 and the tapping machine 5 to abut against the workpiece for processing the workpiece, realizing the function of continuous operation of positioning, processing and material taking of the device workpiece during processing, and improving the processing efficiency of the workpiece.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
