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 major component in the valve. It serves as the housing for internal components such as the valve stem, valve disc and valve seat, and is essential to ensure the correct operation and sealing of the valve. The valve body can be manufactured using different mechanical manufacturing methods, such as casting and forging, according to the pressure level to adapt to medium-low pressure or medium-high pressure working environments. At the same time, the material of the valve body will also be 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 to prevent leakage of the medium. Through processing, it can be ensured that the matching 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 announcement number CN106002275A discloses a thread processing mechanism of a valve body upper cover processing line, which includes a thread push-pull cylinder mounting plate, the upper plane of the thread push-pull cylinder mounting plate is mounted with a thread push-pull cylinder through a cylinder fixing seat, and two parallel thread linear guides are installed on the thread push-pull cylinder mounting plate at a position in front of the thread push-pull cylinder, the thread linear guide has the same movement direction as the thread push-pull cylinder, and a thread push-pull plate is installed on the slider of the thread linear guide; When this structure is in use, the tapping lifting motor drives the screw nut fixing seat to make the tapping lifting plate slide downward, and at the same time, the tapping motor drives the rotating transmission assembly to rotate the first three-jaw connector and the second three-jaw connector. The drill bits on the first three-jaw connector and the second three-jaw connector drill holes in the valve body cover. However, this structure is difficult to achieve continuity in drilling and positioning the workpiece when in use, resulting in low workpiece processing efficiency. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a thread processing mechanism for a valve body upper cover processing line, aiming to solve the problems raised in the above-mentioned background technology.

[0005] The present invention provides the following technical solution: a thread processing mechanism of a valve body upper cover processing line comprises a base, and a linkage component is arranged on the base; The linkage assembly comprises a limit seat arranged on the base, a slide rod is slidably connected to the middle of the limit seat, a pad is fixedly arranged at one end of the slide rod, and a tapping machine for processing is arranged on the pad; A limiting shaft is provided on one side of the surface of the limiting seat, a limiting arc rod is installed on one end of the limiting shaft by a bolt, a stop block for lifting the workpiece is fixedly provided on one end of the limiting arc rod, a rotating sleeve is rotatably connected to the outer side of the limiting shaft, a pressure plate is fixedly provided on one side of the surface of the rotating sleeve, a limiting pin for limiting is inserted on the surface of the pressure plate, a deflection frame is provided on one side of the limiting pin, the deflection frame is rotatably connected to the pressure plate, a contact angle extending to one side of the stop block is provided on the deflection frame, a spring is provided on one side of the surface of the deflection frame, one end of the spring is hooked on the limiting seat, and the rotating sleeve is fixed on a side away from the pressure plate. An extension rod is fixedly provided, and one side of the surface of the limit seat is rotatably connected to a side shaft, a deflection plate is fixedly provided on the side shaft, and the deflection plate extends to the bottom of the extension rod, and a separation plate is provided on one side of the deflection plate, and the separation plate is fixed on the side shaft, and a side extension cover in contact with the extension rod is fixedly provided on the separation plate, and a first gear is provided on the side of the separation plate away from the side extension cover, and the first gear is fixed on the side shaft, and a driving motor installed on a base is provided at the bottom of the first gear, and a second gear is provided at the output end of the driving motor, and the second gear is located at the bottom of the first gear and meshes with the first gear.

[0006] It can be seen that in the above technical solution, the workpiece is blocked by the block, and then the second gear is driven to rotate by the driving motor. 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 deflection plate, the separation plate, the limit sleeve and the arc edge block on the side shaft rotate. When the deflection plate rotates, it contacts the extension rod, and then the extension rod is rotated along the axis point of the connection between the rotating sleeve and the limit shaft through the rotating sleeve, and then the pressure plate is moved closer to the workpiece, and when the pressure plate is deflected, it can also drive the deflection frame and the contact angle to move, so that the contact angle and the pressure plate can easily extend to the outside of the workpiece to position the workpiece, and then realize the function of clamping the workpiece, which is easy to place the workpiece and ensure the stability of the workpiece when clamped; Optionally, in a possible implementation manner, one end of the side shaft is sleeved with two limit sleeves, and each of the limit sleeves is installed on the side shaft by bolts, and arc edge blocks are installed on the two limit sleeves by bolts, and an axle pin seat is installed on one side of the surface of the limit seat by bolts, and a deflection plate is rotatably connected to the axle pin seat, and a sliding shaft is provided at one end of the deflection plate, and the sliding shaft is located between the two arc edge blocks and contacts with the arc edge blocks, a limit ring is provided at the end of the deflection plate away from the sliding shaft, and a resistance ring is provided in the middle of the limit ring, and the resistance ring sleeve is arranged on the outer side of the sliding rod, and a shaft pin bracket is provided on one side of the resistance ring, the shaft pin bracket is located on the sliding rod and is threadedly connected to the sliding rod, and a plurality of hinged rods are hinged on the outer side of the shaft pin bracket, and one end of each of the hinged rods extends to one side of the resistance ring; It can be seen that in the above technical solution, the deflection frame deflects on the pressure plate, which makes it easy for the end of the pressure plate and the contact angle to contact the outside of the workpiece. After the side shaft rotates one circle, the side extension cover can press against the top of the extension rod, and make the extension rod, the rotating sleeve and the pressure plate rotate, so that the contact angle and the pressure plate can be separated from the workpiece, which is convenient for the workpiece to be taken out. At the same time, when the side shaft rotates, it can also drive the limit sleeve and the arc edge block to rotate. When the arc edge block rotates, it rubs against the sliding shaft, and then the sliding shaft pushes the deflection plate to rotate along the axis point of the connection between the deflection plate and the shaft pin seat, and then pushes the limit ring and the contact ring on the sliding rod. When the limit ring and the resistance ring are displaced, they will contact the hinged rod, and then the slide rod can drive the pad and the tapping machine to slide in the limit seat, so that the tapping machine can press the workpiece to perform thread processing, thereby ensuring the processing efficiency. In addition, the side shaft rotates to drive the pressure plate and the deflection frame to displace and clamp the workpiece. At the same time, the deflection plate drives the limit ring to displace and contact the drive motor to drive the slide rod and the tapping machine to resist the workpiece to process the workpiece, thereby realizing the functions of continuous positioning, processing and material removal during the processing of the device workpiece, thereby improving the workpiece processing efficiency.

[0007] Technical effects and advantages of the present invention: 1. The present invention makes contact with the extension rod when the deflection disk rotates, so that the extension rod can rotate along the axis point of the connection between the rotating sleeve and the limit shaft through the rotating sleeve, so that the pressing plate approaches the workpiece, and the deflection of the pressing plate can also drive the deflection frame and the contact angle to move, so that the contact angle and the pressing plate can be extended to the outside of the workpiece to position the workpiece, and then the function of clamping the workpiece is realized, which is easy to place the workpiece and ensure the stability of the workpiece when clamping; 2. When the pressing plate and the deflection frame are deflected, the present invention can also extend the spring through the deflection frame, and make one end of the deflection frame contact with the limit pin, so that the deflection frame is easy to deflect on the pressing plate, and the end of the pressing plate and the contact angle are easy 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, and make the extension rod, the rotating sleeve and the pressing plate rotate, so that the contact angle and the pressing plate can be separated from the workpiece, which is convenient for taking out the workpiece; 3. When the arc edge block rotates, it rubs against the sliding shaft, and then the sliding shaft pushes the deflection plate to rotate along the axis point of the connection between the deflection plate and the shaft pin seat, and then pushes the limit ring and the contact ring to move outside the slide rod. When the limit ring and the contact ring move, they will contact the hinge rod, and then the slide rod can drive the pad and the tapping machine to slide in the limit seat, so that the tapping machine can press the workpiece to perform thread processing, ensuring processing efficiency; To sum up, through the corresponding coordinated use of various structures, the side shaft rotates to drive the pressure plate and the deflection frame to move to clamp the workpiece, while the deflection plate drives the limit ring to move and contact with the drive motor to drive the slide rod and the tapping machine to contact the workpiece to process the workpiece, realizing the functions of continuous positioning, processing and material removal during the processing of the workpiece, thereby improving the workpiece processing efficiency.
