Examples:
as shown in fig. 1 to 4, the present utility model discloses a valve ball clamping device, which comprises a workbench 1, wherein a mounting wall 11 is arranged on the workbench 1, and a telescopic first clamping arm 21 and a telescopic second clamping arm 22 are arranged on the mounting wall 11. In this structure, the first clamp arm 21 and the second clamp arm 22 are disposed opposite to each other, wherein a square 211 is provided on an end of the first clamp arm 21 near the second clamp arm 22, two chamfers 212 are formed on an end of the square 211 near the second clamp arm 22, and the two chamfers 212 are disposed opposite to each other, and two arcuate fixing strips 221 are provided on an end of the second clamp arm 22 near the first clamp arm 21, the two arcuate strips being disposed symmetrically on both sides of the square 211, and further, a length adjusting mechanism is provided on each of the first clamp arm 21 and the second clamp arm 22.
In this structure, the block 211 and the fixing bar 221 are used to fix the valve ball 5, wherein the block 211 is used to be snapped into the valve stem groove 51 on the valve ball 5, the fixing bar 221 is used to press against the surface of the valve ball 5, when the block 211 is aligned with the valve stem groove 51 and both the block 211 and the fixing bar 221 are pressed against the valve ball 5, the valve ball 5 is fixedly clamped, and the length adjusting mechanism mainly functions as: by varying the length of the first clamping arm 21 and the second clamping arm 22 such that the block 211 and the fixing bar 221 can be moved closer to or further away from each other, the effect of releasing or clamping the valve ball 5 is achieved.
The specific structure of the first clamping arm 21 and the second clamping arm 22 is as follows: the first clamping arm 21 and the second clamping arm 22 both comprise a sliding arm 32 and a fixed arm 31, wherein the fixed arm 31 is fixedly arranged on the mounting wall 11, a connecting rod 311 is fixedly arranged at the end part of the fixed arm 31 far away from the mounting wall 11, a sliding block 312 is fixedly arranged at the end part of the connecting rod 311 far away from the fixed arm 31, the sliding block 312 is slidably arranged inside the sliding arm 32, and a sliding groove 321 for sliding the sliding block 312 is correspondingly formed inside the sliding arm 32.
The length adjusting mechanism comprises a limiting ring 33 and an elastic supporting piece 34. Looking first at the resilient abutment 34: the elastic supporting piece 34 is arranged in the sliding groove 321 and is used for pushing the sliding block 312 outwards, and the elastic supporting piece 34 is preferably a spring; looking again at stop collar 33: the inner side wall of the limit ring 33 and the outer side wall of the connecting rod 311 are provided with threads, and the limit ring 33 is connected to the connecting rod 311 in a threaded manner and is positioned between the sliding arm 32 and the fixed arm 31.
The working principle of the structure is as follows: when the valve ball 5 needs to be clamped, the square 211 and the fixing strip 221 can be firstly spread by hands, then the valve ball 5 is placed between the square 211 and the fixing strip 221, and the valve rod groove 51 on the valve ball 5 is aligned to the square 211, at the moment, the square 211 and the fixing strip 221 are loosened, the spring can automatically push the sliding arm 32 to slide towards the valve ball 5, so that the valve ball 5 is clamped by the square 211 and the fixing strip 221, and if the valve ball 5 only needs to be inspected, no polishing tool applies external force to the valve ball, then the clamping force spring required by the valve ball 5 is enough to provide. If the valve ball 5 needs to be subjected to lip polishing or other polishing work, in order to avoid the valve ball 5 from being extruded between the square 211 and the fixed strip 221 by external force, the limiting ring 33 can be rotated, so that the limiting ring 33 is abutted against the end part of the sliding arm 32, and the square 211 and the sliding arm 32 can be always pressed on the valve ball 5, thus the problem that the valve ball 5 is extruded between the square 211 and the fixed strip 221 in the polishing process can be prevented.
The mounting wall 11 is arranged on the workbench 1 in a closed annular mode in a rotating mode, a first gear 41, a second gear 42 and a motor 43 are further arranged on the workbench 1, wherein the first gear 41 is sleeved on the outer side of the mounting wall 11 and fixedly connected with the mounting wall 11, the second gear 42 is arranged on the workbench 1 in a rotating mode and meshed with the first gear 41, and the motor 43 is fixedly arranged on the workbench 1 and the output end of the motor is connected with the second gear 42.
The working principle of the structure is as follows: when the valve ball 5 needs to rotate during polishing, the motor 43 can drive the mounting wall 11 to rotate through the engagement of the first gear 41 and the second gear 42, and thus the valve ball 5 rotates.
