Description

Technical Field

[0001] The utility model relates to the technical field of valve ball detection, in particular to a valve ball clamp with a double clamping solution. Background Art

[0002] A valve is a control component used to control whether a liquid medium can flow. A ball valve is a type of valve. The working principle of a ball valve is to control the flow of fluid through the angle of the valve ball, thereby achieving control of the fluid.

[0003] The valve ball in the ball valve needs to be inspected before or after drilling to ensure the quality and service life of the ball valve after manufacture. When the valve ball is inspected, it is usually necessary to clamp it. Existing valve ball clamps, such as a valve ball detection clamping device disclosed in application No. 202120587344.2, generally use a double-sided clamping solution for the valve ball. Although this double-sided clamping solution has a greater clamping force, it will cover a larger area of ​​the valve ball surface, affecting the staff's observation of the valve ball surface. In addition, this clamping method is relatively cumbersome. If the valve ball only needs to be tested for simple items such as radial runout, this clamping solution will result in reduced detection efficiency. Utility Model Content

[0030] Reference Figure 1-Figure 4According to an embodiment of a valve ball clamp of a double clamping scheme of the utility model, it includes a detection platform 11, a hinged plate 12 is hinged in the detection platform 11, and a cylinder 13 is fixed on the side of the hinged plate 12, a piston rod 14 extending from the cylinder 13 is connected to a cylinder 15 through a connecting mechanism, because the hinged plate 12 can swing, so that the cylinder 15 can be in a horizontal or vertical state, a No. 1 boss is provided in the end surface of the cylinder 15 away from the piston rod 14, and a No. 1 concave surface 16 is provided in the No. 1 boss, a positioning mechanism 101 for controlling the angle of the hinged plate 12 is provided in the detection platform 11, a fixed plate 17 is also fixed on the upper side of the detection platform 11, a rotating column 18 is provided on the side of the fixed plate 17 facing the hinged plate 12, and a No. 2 boss is provided on the end surface of the rotating column 18, and a No. 2 boss is provided in the No. 2 boss. A No. 2 concave surface 19 is provided;

[0031] When the positioning mechanism 101 controls the cylinder 15 to be in a horizontal state, the piston rod 14 can extend and clamp the valve ball between the second concave surface 19 and the first concave surface 16. When the positioning mechanism 101 controls the cylinder 15 to be in a vertical state, the valve ball can be located in the first concave surface 16. The two methods of clamping the valve ball make it easy for the staff to detect the valve ball.

[0032] In this embodiment, the positioning mechanism 101 includes a baffle 20 slidably connected to the upper side of the detection platform 11, and a groove for accommodating the hinge plate 12 is provided in the baffle 20. The left and right widths of the groove are consistent with the thickness of the baffle 20. When the baffle 20 moves to the frontmost side, the hinge plate 12 can be inserted into the groove. At this time, the hinge plate 12 remains in a vertical state, and the cylinder 15 faces rightward, so as to cooperate with the cylinder 15 to clamp the valve ball.

[0033] A receiving groove 31 is provided in the upper side surface of the detection platform, and the hinge plate 12 is hinged in the receiving groove 31. When the baffle 20 moves to the rearmost side and releases the lock on the hinge plate 12, the left side surface of the hinge plate 12 can be attached to the lower side surface of the receiving groove 31, and the cylinder 15 faces upward.

[0034] In one embodiment of the connecting mechanism, the connecting mechanism includes a rotating shaft 21 rotatably connected to the end of the piston rod 14, the cylinder 15 is fixed to the end of the rotating shaft 21, and the No. 1 concave surface 16 is away from the rotating shaft 21. In addition, a piston chamber 22 is provided in the cylinder 15, and a negative pressure hole penetrating the No. 1 concave surface 16 is provided in the side of the piston chamber 22. A piston 23 is slidably connected to the piston chamber 22 left and right, and a negative pressure mechanism for controlling the position of the piston 23 is provided on the rotating shaft 21. When the cylinder 15 is in a vertical state, the valve ball can be controlled by the negative pressure mechanism and attached to the No. 1 concave surface 16 to avoid shaking or falling out, thereby increasing the clamping force.

[0035] The negative pressure mechanism includes a ring 24 arranged on the end face of the piston 23, the ring 24 passes through the piston cavity 22, and the ring 24 is sleeved on the outside of the rotating shaft 21, a positioning plate 25 is hinged in the ring 24, and a plurality of grooves 26 for accommodating the positioning plate 25 are equidistantly provided on the left and right sides of the side surface of the rotating shaft 21. After placing the valve ball in the No. 1 concave surface 16, the staff drags the ring 24 downward to make the piston 23 move to the left. At this time, negative pressure is generated in the piston cavity 22 and the valve ball is adsorbed. Then the staff embeds the positioning plate 25 into the groove 26 to lock the position of the piston 23.

[0036] In order to facilitate the staff to control the positioning plate 25, the left side of the slot 26 is an inclined surface, a spring plate 28 is provided on the side of the ring 24, and the transverse extension part in the spring plate 28 is connected to the positioning plate 25 through a No. 1 spring. A hook plate 29 is provided on the upper side of the positioning plate 25. The No. 1 spring makes the positioning plate 25 tend to be always in the slot 26. The setting of the inclined surface makes the positioning plate 25 only move to the left without being pulled out. Two symmetrically distributed convex strips 27 are also provided in the side of the ring 24. The piston 23 is connected to the side of the piston chamber 22 through a No. 2 spring to facilitate the reset of the piston 23. (The above-mentioned piston 23 is facing left, and the slots 26 are set at equal distances on the left and right in the rotating shaft, etc. are all in the horizontal state of the cylinder 15).

[0037] The specific operation process is as follows: when the column 15 is in a vertical state, the staff drives the ring 24 downward through the convex strip 27. During this process, the positioning plate 25 will be embedded in the slot 26 under the action of the No. 1 spring. When the ring 24 reaches the position, the staff lets go. At this time, the positioning plate 25 will be restricted and reset by the vertical surface in the slot 26. At this time, the valve ball is adsorbed and fixed in the No. 1 concave surface 16.

[0038] When unlocking is required, the staff pulls the positioning plate 25 through the hook plate 29 to make it leave the clamping groove 26, at which time the piston 23 is reset and the valve ball is no longer adsorbed and fixed.

[0039] When the valve ball to be tested is relatively large, the staff can place the piston rod 14 flat and control the cylinder 13 so that the large valve ball is clamped between the cylinder 15 and the rotating column 18;

[0040] When the valve ball to be tested is small, the staff can place the piston rod 14 in a vertical state, and allow the small valve ball to be adsorbed into the first concave surface 16 by negative pressure.

[0041] The rotatable design of the rotating shaft 21 and the rotating column 18 enables the clamped valve ball to rotate, which is convenient for detection.

[0042] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
