Description

Technical Field

[0001] The invention relates to the technical field of valve stem processing, and more specifically, to a valve stem manufacturing and processing system for valve accessories. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. The valve stem is an important component of the valve, used for transmission, connected to the actuator or handle on the top, and directly drives the valve core to move or rotate below to realize the valve switching or regulation function.

[0003] When producing valve stems, the grooved valve stems need to be polished by polishing equipment to ensure the accuracy of the valve stems. In the prior art, two sets of top columns are coaxially abutted against the two ends of the valve stem and can drive it to rotate. The rotating grinding wheel is controlled to move along the length direction of the valve stem at the same time, thereby achieving all-round polishing of the valve stem.

[0004] However, before each grinding, the valve stem and the two sets of top columns need to be coaxially adjusted. There are errors in the process of manual coaxial adjustment, which affects the normal progress of grinding. At the same time, after completing the coaxial adjustment, the position of the valve stem is prone to shift during the rotational grinding process, which reduces the grinding accuracy.

[0037] A side plate 59 is fixed to the end of the arc plate 44; a second rotating motor 60 electrically connected to the output end of the controller 24 is fixedly installed on the side of the side plate 59; a reciprocating screw rod 61 is fixed to the output end of the second rotating motor 60; a through groove 78 is opened on the inner bottom surface of the arc plate 44; a sliding sleeve 62 slidingly matched with the through groove 78 is slidably arranged on the reciprocating screw rod 61; a first pressure sensor 63 electrically connected to the input end of the controller 24 is fixed to one side of the sliding sleeve 62, and a push rod 64 is fixed to the other opposite side thereof; a second pressure sensor 65 electrically connected to the input end of the controller 24 is fixedly installed on the side of a fixed frame 2; a positioning rod 79 is fixed to the side of a fixed frame 2; a baffle 80 coaxial with the push rod 64 is fixed to the end of the positioning rod 79.

[0038] Working principle of the second embodiment: Each group of valve stems 16 to be polished is placed in the storage box 40 from top to bottom. In the initial state, the bottom valve stem 16 is placed inside the semi-ring plate 45. The controller 24 controls the start-up drive motor 23 to drive the corresponding shaft 3 to rotate. Through the mutual engagement of the two groups of gears 22, the shaft 3 below is driven to rotate synchronously in the opposite direction, thereby driving the two groups of pulleys 10 placed on the top and the two groups of pulleys 10 placed on the bottom to rotate synchronously in the opposite direction, realizing the synchronous reverse transmission of the upper and lower groups of belts 14 on the same group of transmission parts 5, and the valve stem 16 is placed in two coaxial arc grooves 15, so as to realize the transportation of the valve stem 16. When the infrared travel switch 21 is blocked by the corresponding shading plate 19, the infrared travel switch 21 transmits a signal to the controller 24, and the controller 24 controls the driving motor 23 to stop working, so as to realize the transportation of the valve stem 16 to the specified position. The position of the valve stem 16 coaxial with the push rod 64 is the feeding position, the position of the valve stem 16 coaxial with the push rod 18 is the grinding position, and the position of the valve stem 16 coaxial with the sleeve 49 is the discharging position.

[0039] After completing the grinding of a group of valve stems 16, the drive motor 23 is controlled to rotate so that the grinded valve stems 16 are transported to the discharge station, and the third electric push rod 48 is controlled to start and extend, and the valve stems 16 at the discharge station are pushed into the discharge part 67 through the sleeve 49 to complete the unloading, thereby preventing the grinding chips generated in the subsequent grinding process from causing secondary contamination to the polished valve stems 16.

[0040] During the extension process of the third electric push rod 48, the ball head 55 at the end of the ear rod 54 is driven to enter the second straight guide groove 53 along the first straight guide groove 52 through the spiral groove 51. After the ball head 55 slides from the first straight guide groove 52 into the spiral groove 51, the rotating rod 50 is driven to rotate. When the ball head 55 slides from the spiral groove 51 into the second straight guide groove 53, the rotating rod 50 stops rotating. In this process, the rotating rod 50 rotates 180°, thereby driving the first sprocket 56 to rotate 180°, and through the transmission of the chain 58, the second sprocket 57 is driven to rotate 180°, thereby driving The semi-ring plate 45 rotates 180 degrees to separate the valve stem 16 at the bottom of the storage box 40 from the second-to-last valve stem 16, and the valve stem 16 at the bottom falls into the arc plate 44. When the end of the third electric push rod 48 extends to abut against the second pressure sensor 65, the second pressure sensor 65 transmits a signal to the controller 24, and the controller 24 controls the third electric push rod 48 to stop. At the same time, the second rotary motor 60 is controlled to start and drive the reciprocating screw 61 to rotate. A slider is provided inside the sliding sleeve 62. The reciprocating screw 61 is a form of a three-dimensional cam pair. The performance is that two thread grooves 66 with the same pitch and opposite rotation direction are connected at both ends by a transition curve. Through the rotation of the reciprocating screw rod 61, the side of the spiral groove 51 pushes the slider placed in the spiral groove 51 to make axial reciprocating motion, thereby driving the push rod 64 to slide in the direction away from the second rotating motor 60, and pushing the valve stem 16 placed in the arc plate 44 into the feeding station. When the end of the valve stem 16 abuts against the side of the baffle 80, the sliding sleeve 62 just moves and changes direction, moving in the direction close to the second rotating motor 60. When the first pressure sensor 63 moves When it is pressed on the end of the arc plate 44, the first pressure sensor 63 transmits a signal to the controller 24, and the controller 24 controls the second rotating motor 60 to stop, completing a cycle of movement and reversal reset of the sleeve 62. At the same time, the third electric push rod 48 is controlled to shrink and reset, so that the ball head 55 passes through the spiral groove 51 along the second straight guide groove 53 and enters the first straight guide groove 52, completing the reverse rotation and reset of the semi-ring plate 45. In the initial state, the second to last valve stem 16 is placed inside the semi-ring plate 45, completing the automatic loading and unloading of the valve stem 16, thereby improving work efficiency.
