Description

Technical Field

[0001] The invention relates to the technical field of three-way ball valve ball processing, in particular to a clamp for three-way ball valve ball processing. Background Art

[0002] The three-way ball valve is a new type of valve that has been widely used in recent years. Its principle is to automatically open and close the ball by rotating it 90 degrees under the action of fluid. The three-way ball valve not only has a simple structure and good sealing performance, but also opens and closes quickly and reciprocates 90 degrees without friction, which completely solves the problem of traditional angle valves affecting sealing due to mutual friction between sealing surfaces.

[0003] During the processing of the three-way ball valve, it is necessary to punch holes in the horizontal direction and the top of the ball of the three-way ball valve so that the three orthogonal pipes are interconnected. In the prior art, the ball of the three-way ball valve is mostly fixed by a clamp, and then the ball of the three-way ball valve is punched using a punching device. However, since the surface of the ball of the three-way ball valve is relatively smooth, it is difficult to fix and clamp it with the existing clamp. During the process of punching the ball of the three-way ball valve, the position of the hole may deviate due to the insufficient stability of the clamping of the ball of the three-way ball valve, which seriously affects the processing quality of the ball.

[0014] The beneficial effects are:

[0015] 1. The present invention pushes the large limit frame to move upward through the electric push rod, so that the large suction cup moves upward and sucks the three-way ball valve ball, and then clamps the bottom of the three-way ball valve ball. At the same time, the two inclined slide rails move upward to drive the two small suction cups to move, clamping the left and right sides of the three-way ball valve ball, thereby further clamping the three-way ball valve ball, so that the three-way ball valve ball is placed more stably, so as to stably punch a hole in the three-way ball valve ball.

[0016] 2. The present invention drives the push plate to move upward through the electric push rod, and the push plate pushes the piston to move upward, squeezing the hydraulic oil between the small limit frame and the pressure plate, and pushing the pressure plate to move. The movement of the two pressure plates will first contact the left and right sides of the three-way ball valve ball, and squeeze the three-way ball valve ball, increase the friction between the three-way ball valve ball, and then more stably clamp the two sides of the three-way ball valve ball, avoid the three-way ball valve ball from rolling, and enable the three-way ball valve ball to be more stably placed on the curved cylinder, so that the staff can more stably punch the three-way ball valve ball.

[0017] 3. The present invention drives the small annular frame to move upward through the electric push rod, so that the driving movable rod moves in the direction away from the three-way ball valve ball, and then the lateral movable rod moves. The movement of the lateral movable rod will push the three-way ball valve ball to rotate, thereby correcting the position of the three-way ball valve ball, so that the three-way ball valve ball can be placed more correctly, so that the punching equipment can align with the position of the three-way ball valve ball for punching, and the three-way ball valve ball can be punched more accurately.

[0018] 4. The present invention pushes the longitudinal movable rod upward through the electric push rod, so that the pressure block moves upward and contacts with the bottom of the three-way ball valve ball. The longitudinal movable rod continues to move upward to compress the pressure spring. At the same time, under the elastic force of the pressure spring, the pressure block will cling to the bottom of the three-way ball valve ball, increasing the friction between the pressure block and the three-way ball valve ball, thereby more stably clamping the three-way ball valve ball, avoiding inaccurate drilling caused by the movement of the three-way ball valve ball when drilling the three-way ball valve ball, thereby improving the processing quality of the three-way ball valve ball.

[0032] The initial clamping mechanism includes a double slide rail 51, a curved slider 52, a large limit frame 53 and a large suction cup 54. The double slide rail 51 is connected to the inner top of the curved cylinder 2 by bolts. Two curved sliders 52 are slidably connected to the double slide rail 51.

[0036] In actual operation, the staff first places the three-way ball valve ball 21 that needs to be punched on the top of the curved cylinder 2, and then starts the electric push rod 4. The telescopic rod of the electric push rod 4 quickly extends to contact the bottom of the large limit frame 53, and pushes the large limit frame 53 to move upward. The large suction cup 54 moves upward, which drives the two curved sliders 52 to move upward together.

The large limit frame 53 moves upward and drives the two curved sliders 52 to move upward. The inclined slide rail 65 moves upward, and the upward movement of the two inclined slide rails 65 will push the two transverse limit rods 64 to move in a direction close to each other. The movement of the two transverse limit rods 64 will drive the two transverse slide rails 62 to move in a direction close to each other. The movement of the transverse slide rail 62 will drive the small limit frame 63 and the small suction cup 66 to move together. The two small suction cups 66 move in a direction close to each other and contact with the three-way ball valve ball 21, and clamp the left and right sides of the three-way ball valve ball 21, thereby further clamping the three-way ball valve ball 21, so that the three-way ball valve ball 21 is placed more firmly. After the ball 21 is stabilized, the staff can then punch holes in the horizontal direction and the top of the three-way ball valve ball 21; when the three-way ball valve ball 21 is punched, the telescopic rod of the electric push rod 4 will quickly shrink and disengage from the large limit frame 53, and the large limit frame 53, the curved slider 52 and the large suction cup 54 will reset downward together under the action of gravity, and the large suction cup 54 will reset downward and disengage from the three-way ball valve ball 21, and the curved slider 52 will be blocked by the double slide rails 51 when it resets downward and will no longer move downward, and the large limit frame 53 will reset downward to drive the two inclined slide rails 65 is reset downward, and the downward reset of the two inclined slide rails 65 will push the two lateral limit rods 64 to reset in the direction away from each other, and the reset of the lateral limit rod 64 will drive the lateral slide rail 62 to reset, and the reset of the lateral slide rail 62 will drive the small limit frame 63 and the small suction cup 66 to reset together, and the reset of the two small suction cups 66 will be out of contact with the three-way ball valve ball 21, and then the staff will take out the punched three-way ball valve ball 21 from the top of the curved tube 2, and then place a new three-way ball valve ball 21, and repeat this process to quickly punch the three-way ball valve ball 21.

[0037] Example 2

[0038] On the basis of Example 1, Figure 3-Figure 7As shown, it also includes a hydraulic pressurizing mechanism, which is arranged on the electric push rod 4. The hydraulic pressurizing mechanism includes a push plate 71, a connecting ring 72, a hard tube 73, a soft tube 74, a pressure plate 75, a piston 76 and a tension spring 77. The telescopic rod of the electric push rod 4 is connected to two push plates 71 by bolts, and the two push plates 71 are symmetrically arranged. The connecting ring 72 is connected to the outer wall of the large limit frame 53 by bolts. Two hard tubes 73 are fixedly connected to the connecting ring 72. The two hard tubes 73 are symmetrically arranged. The upper ends of the two hard tubes 73 Both are fixedly connected with a soft tube 74, and the hard tube 73 is connected with the soft tube 74, the soft tube 74 is made of soft material, and the two soft tubes 74 pass through the top of the curved cylinder 2, and the other end of the soft tube 74 is connected with the small limit frame 63, and the two small limit frames 63 are slidably connected with a pressure plate 75, and the pressure plate 75 is slidably connected with the small suction cup 66, and the lower end inner wall of the two hard tubes 73 is slidably connected with a piston 76, and the piston 76 is located directly above the push plate 71, and a tension spring 77 is connected between the small limit frame 63 and the pressure plate 75 through a hook.

[0039] Initially, the rigid tube 73 and the flexible tube 74 are both filled with hydraulic oil, and the space between the small limit frame 63 and the pressure plate 75 is also filled with hydraulic oil. When the telescopic rod of the electric push rod 4 is rapidly extended, the two push plates 71 are driven to move upward together. The push plates 71 move upward to contact the piston 76 and push the piston 76 to move upward. At the same time, the movement of the small suction cup 66 drives the pressure plate 75 to move. The upward movement of the piston 76 pushes the hydraulic oil in the rigid tube 73 into the flexible tube 74. The hydraulic oil will flow between the small limit frame 63 and the pressure plate 75, and push the pressure plate 75 to move. When the large limit frame 53 moves upward, it will drive the connecting ring 72 to move upward. The connecting ring 72 moves upward and drives the two rigid tubes 73 to move upward. The two pressure plates 75 move toward each other and will first contact the left and right sides of the three-way ball valve ball 21. When the two small suction cups 66 contact the three-way ball valve ball 21, the three-way ball valve ball 21 will squeeze the two pressure plates 75, and the hydraulic oil will also The pressing plate 75 is pushed so that the pressing plate 75 squeezes the three-way ball valve ball 21, increases the friction between the pressing plate 75 and the three-way ball valve ball 21, and then clamps the two sides of the three-way ball valve ball 21 more stably to prevent the three-way ball valve ball 21 from rolling, so that the three-way ball valve ball 21 can be placed more stably on the curved cylinder 2, so that the staff can punch the three-way ball valve ball 21 more stably; when the telescopic rod of the electric push rod 4 is quickly contracted, it will drive the two push plates 71 to reset downward together, and the push plates The downward reset of 71 will disengage from the piston 76, the downward reset of the large limit frame 53 will drive the connecting ring 72 to reset downward, the upward movement of the connecting ring 72 will drive the two rigid tubes 73 to reset downward, and the reset of the tension spring 77 will drive the reset of the pressure plate 75, the reset of the pressure plate 75 will disengage from the three-way ball valve ball 21, the reset of the pressure plate 75 will squeeze the hydraulic oil back into the flexible tube 74, the hydraulic oil in the flexible tube 74 will flow back into the rigid tube 73, and push the piston 76 to reset downward.

[0040] Example 3

[0041] On the basis of Example 2, Figure 2-Figure 9As shown, a correction mechanism is also included, which is arranged on the electric push rod 4. The correction mechanism includes a small annular frame 81, an inclined straight guide rail 82, a sliding long rod 83, a transverse movable rod 84, a connecting frame 85 and a driving movable rod 86. The small annular frame 81 is connected to the telescopic rod of the electric push rod 4 by bolts, and the small annular frame 81 is located below the two push plates 71. The inclined straight guide rail 82 is connected to the small annular frame 81 by bolts. The sliding long rod 83 is slidably connected to the upper part of the curved cylinder 2. The sliding long rod 83 is horizontally arranged. The transverse movable rod 84 is bolted to the top middle side of the sliding long rod 83. The transverse movable rod 84 contacts the bottom of the three-way ball valve ball 21. The connecting frame 85 is bolted to the bottom of the sliding long rod 83. The connecting frame 85 is vertically arranged. The driving movable rod 86 is bolted to the lower part of the connecting frame 85, and the driving movable rod 86 is slidably connected to the inclined straight guide rail 82.

[0042] Initially, when the three-way ball valve ball 21 is placed on the top of the curved cylinder 2, it will contact the transverse movable rod 84. When the telescopic rod of the electric push rod 4 is quickly extended, the small annular frame 81 will be driven to move upward. The upward movement of the small annular frame 81 will drive the inclined straight guide rail 82 to move upward. The upward movement of the inclined straight guide rail 82 will first push the driving movable rod 86 and the connecting frame 85 to move away from the three-way ball valve ball 21. The movement of the connecting frame 85 will drive the sliding long rod 83 and the transverse movable rod 84 to move away from the three-way ball valve ball 21. The movement of the transverse movable rod 84 will push the three-way ball valve ball 21 to rotate, and the position of the three-way ball valve ball 21 will be adjusted. Correction is performed so that the three-way ball valve ball 21 can be placed more correctly, so that the punching equipment can align with the punching position of the three-way ball valve ball 21, and the three-way ball valve ball 21 can be punched more accurately. The oblique straight guide rail 82 continues to move upward and will no longer push the driving active rod 86 and the connecting frame 85; the rapid contraction of the telescopic rod of the electric push rod 4 will drive the small annular frame 81 to reset downward, and the downward reset of the small annular frame 81 will drive the oblique straight guide rail 82 to reset downward, and the downward reset of the oblique straight guide rail 82 will push the driving active rod 86 and the connecting frame 85 to reset together, and the reset of the connecting frame 85 will drive the sliding long rod 83 and the horizontal active rod 84 to reset together.

[0043] Example 4

[0044] On the basis of Example 3, Figure 6-Figure 7 As shown, a spring pressure mechanism is also included, and the spring pressure mechanism is arranged on the large suction cup 54.

A pressure spring 92 is connected between the pressure block 91 and the longitudinal movable rod 93 by bolts.

[0045] When the telescopic rod of the electric push rod 4 is quickly extended, it will first contact the longitudinal movable rod 93 and push the longitudinal movable rod 93 to move upward. The upward movement of the longitudinal movable rod 93 will drive the pressure block 91 to move upward through the pressure spring 92. The pressure block 91 moves upward and contacts the bottom of the three-way ball valve ball 21 and stops moving upward. The longitudinal movable rod 93 continues to move upward, which will compress the pressure spring 92. When the large suction cup 54 contacts the bottom of the three-way ball valve ball 21, the longitudinal movable rod 93 stops moving upward. Under the elastic force of the pressure spring 92, the pressure block 91 The block 91 will be in close contact with the bottom of the three-way ball valve ball 21, increasing the friction between the block 91 and the three-way ball valve ball 21, thereby clamping the three-way ball valve ball 21 more stably, avoiding the movement of the three-way ball valve ball 21 when punching the three-way ball valve ball 21, resulting in inaccurate punching, thereby improving the processing quality of the three-way ball valve ball 21; when the telescopic rod of the electric push rod 4 is quickly contracted, it will be out of contact with the longitudinal movable rod 93, and the reset of the pressure spring 92 will drive the pressure block 91 to move downward, and then the pressure block 91 and the longitudinal movable rod 93 will be reset downward under the action of gravity.

The three-way ball valve ball 21 is located in the buffer ring 10, and the three-way ball valve ball 21 is in contact with the buffer ring 10.

[0048] The buffer ring 10 can increase the friction between the curved cylinder 2 and the three-way ball valve ball 21, so that the three-way ball valve ball 21 can be placed more stably.
