The lower side of the mounting plate 3 is rotatably connected with a first connecting shaft 32, the upper end of the first connecting shaft 32 stretches into the accommodating groove 31, a third chain wheel 33 is coaxially fixed at the lower end of the first connecting shaft 32, the third chain wheel 33 is meshed with a chain 64, a first belt wheel 34 is coaxially fixed at the upper end of the first connecting shaft 32, the mounting plate 3 is positioned in the accommodating groove 31 and is fixedly provided with a second connecting shaft 35, a second belt wheel 36 is coaxially fixed on the second connecting shaft 35, a belt 37 is wound on the first belt wheel 34 and the second belt wheel 36, an eccentric rod 361 is fixedly arranged at the lower side of the second belt wheel 36, the eccentric rod 361 and the second belt wheel 36 are eccentrically arranged, the mounting plate 3 is in the accommodating groove 31 and is in lifting sliding movement with a lifting plate 20, the lifting plate 20 is positioned at the lower side of the second belt wheel 36, the mounting plate 3 is in the accommodating groove 31 and is fixedly provided with guide posts 38, the guide posts 38 are vertically arranged, two guide posts 38 are arranged, two ends of the lifting plate 20 are spliced and the two guide posts 38 are in sliding movement fit, the guide posts 38 are sleeved with abutting springs 381, the abutting springs are abutted against the lower sides of the lifting plate 20 and the inner walls of the lifting plate 381 are abutted against the inner walls of the connecting plates 10, and the other ends of the connecting plates are fixedly connected with the lifting plate 381, and the inner ends of the lifting plate 20 are abutted against the connecting rods 10.
Referring to fig. 8 and 9, the driving wheel 30 is rotatably connected to the upper side of the lifting plate 20, an arc groove 301 is formed in the driving wheel 30, the curvature center of the arc groove 301 is located at the center of the driving wheel 30, the bottom wall of the arc groove 301 is wedge-shaped, that is, two ends of the arc groove 301 are respectively the lowest end and the highest end, the eccentric rod 361 extends into the arc groove 301 and is in sliding fit with the arc groove 301, and in an initial state, the eccentric rod 361 is located at the lowest end of the arc groove 301.
When the lower end of the linkage column enters the avoidance groove 82, the driving motor 61 drives the rotation sleeve 5 to rotate along with the rotation sleeve, meanwhile, the third chain wheel 33 rotates, the third chain wheel 33 drives the first belt wheel 34 to rotate, the first belt wheel 34 drives the second belt wheel 36 to rotate through the belt 37, when the second belt wheel 36 rotates, the eccentric rod 361 slides in the arc-shaped groove 301 of the driving wheel 30 and slides from the lowest end to the highest end of the arc-shaped groove 301, then the second belt wheel 36 drives the driving wheel 30 to synchronously rotate, when the eccentric rod 361 slides from the lowest end to the highest end of the arc-shaped groove 301, the driving wheel 30 descends due to the fact that the height difference exists between the lowest end and the highest end, the connecting rod 10 is driven to descend through the lifting plate 20, sliding of the locking block 73 is achieved, the locking block 73 slides and is matched with the locking groove 83, coaxial running fit of the linkage rod 7 and the linkage disc 8 is achieved, and then the drilling rod can be driven to rotate. When the drilling is finished, the driving motor 61 stops rotating, at this time, the abutting spring 381 acts on the lifting plate 20, the lifting plate 20 rises, the eccentric rod 361 is reset to the lowest end of the arc-shaped groove 301, and the driving rod 9 also rises along with the lifting locking block 73 to retract into the linkage rod 7 under the action of the reset spring 74 and is separated from the locking groove 83.
The drilling device for the valve clack of the regulating valve is implemented by placing the valve clack on a base 1 and between three clamping plates 21, driving a disc 22 to rotate to drive the three clamping plates 21 to slide in opposite directions, clamping and fixing the valve clack, starting a driving motor 61, coaxially rotating and matching a linkage rod 7 and a first drill rod 41 at the moment, rotating a rotating sleeve 5 to further realize the rotation of the first drill rod 41, lowering a mounting plate 3 to realize the formation of a first drilling hole of the valve clack, lifting the mounting plate 3 after the formation, stopping the driving motor 61, coaxially rotating and matching the linkage rod 7 and the first drill rod 41, rotating a rotating plate 4, moving a second drill rod 42 to the lower side of the linkage rod 7, starting the driving motor 61, coaxially rotating and matching the linkage rod 7 and the second drill rod 42 at the moment, and lowering the mounting plate 3 to realize the formation of a second drilling hole of the valve clack. Through the drilling device, the first drilling hole and the second drilling hole can be formed at one time, the drilling device is quicker, the valve clack does not need to be transported, the labor intensity is reduced, and the processing efficiency is improved.
The drilling process of the valve clack of the regulating valve adopts the drilling device and comprises the following steps:
s1, placing a valve clack on a base 1, and clamping, fixing and centering the valve clack by three clamping plates 21;
S2, the mounting plate 3 descends, the first drill rod 41 drills the valve clack to form a first drill hole, and then the mounting plate 3 resets;
S3, rotating the rotating plate 4, moving the second drill rod 42 to the upper part of the valve clack, descending the mounting plate 3, and drilling the valve clack by the second drill rod 42 to form a second drilling hole;
s4, detaching the valve clack.
The above embodiments are not intended to limit the scope of the application, so that the equivalent changes of the structure, shape and principle of the application are covered by the scope of the application.
