Description

Technical Field

[0001] This invention relates to the field of valve body clamping, and in particular to a high-pressure water cleaning shell rotary clamping device. Background Technology

[0002] Products made using investment casting will have a shell bonded by sand on their surface after casting. The shell is highly adhered to the valve body, making it very difficult to remove after casting.

[0003] Furthermore, when cleaning and removing the surface shell of the valve body, the shell peels off layer by layer, and the overall shape gradually shrinks, which makes positioning and locking difficult.

[0004] In summary, how to achieve valve body cleaning and continuous valve body positioning has become an urgent problem for researchers in this field. Summary of the Invention

[0005] The technical problem to be solved by this invention is: how to achieve the cleaning of the valve body and the continuous positioning and locking of the valve body during cleaning.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] This invention relates to a high-pressure water cleaning shell rotary clamping device, comprising: a worktable; an electric rotary table rotatably mounted on the worktable; a support assembly mounted on the electric rotary table and adapted to support the bottom of a valve body; a column vertically mounted on the worktable; and a clamping assembly fixedly connected to the column and located above the valve body, adapted to clamp the valve body; the bottom of the valve body is placed on the support assembly, and its top is clamped by the clamping assembly; the electric rotary table rotates, causing the valve body to rotate synchronously.

[0008] In this solution, the bottom of the valve body is supported on a support assembly, which is set on an electric turntable. The clamping assembly is set on the top of the valve body via a column, and the clamping assembly always acts on the top of the valve body. In this way, the valve body is positioned by supporting the top and bottom of the valve body. The electric turntable rotates, which drives the valve body to rotate. Abrasive is added to the high-pressure water, and the valve body on the rotating fixture is cleaned by scanning. Finally, all the shell covering the surface of the product is removed, and the required parts are obtained, thus achieving the cleaning of the valve body.

[0009] Furthermore, in this design, the horizontal section of the column can be adjusted to raise or lower the vertical section, allowing the clamping assembly to be positioned at a suitable height relative to the valve body.

[0010] To illustrate the specific structure of the support assembly, the present invention uses a support assembly comprising: a sliding groove formed on the electric turntable; two sliders slidably disposed within the sliding groove; and a V-shaped support block fixedly connected to the corresponding slider, which is adapted to support the bottom of the valve body.

[0011] Two sliders are slidably set in the sliding groove to accommodate valve bodies of different lengths. The sliders are fixed to the V-shaped support blocks, and the valve body is supported on the two V-shaped support blocks, thus achieving the support of the valve body.

[0012] In order to clean the valve body surface as much as possible, the present invention uses an arc-shaped cross-section for the V-shaped support block;

[0013] This way, the V-shaped support block makes point contact with the valve body, which helps to clean the surface of the valve body and prevents the support from being left uncleaned.

[0014] To illustrate the specific structure of the clamping assembly, the present invention uses a clamping assembly comprising: a cylinder body with an air inlet at the top; a cylinder cover disposed at the bottom of the cylinder body; and a piston rod movably disposed within the cylinder body, with its end abutting against the valve body; gas is introduced into the cylinder body through the air inlet, thereby driving the piston rod to move up and down.

[0015] Gas is introduced into the cylinder through the air inlet, which in turn drives the piston rod to move up and down, pressing the end of the piston rod against the top of the valve body to seal and position the top of the valve body.

[0016] In order to achieve point contact between the piston rod end and the valve body, the present invention uses a ball at the piston rod end, and the ball makes point contact with the top of the valve body;

[0017] The ball makes point contact with the top of the valve body, which facilitates cleaning of the valve body surface.

[0018] To illustrate the specific structure of the cylinder body, the present invention employs a cylinder body with a first stepped hole, a second stepped hole, and a third stepped hole arranged sequentially from top to bottom, each with a gradually increasing cross-section. The piston rod is arranged sequentially from top to bottom with a first piston for sealing the first stepped hole, a second piston for sealing the second stepped hole, and a third piston for sealing the third stepped hole. The first stepped hole and the first piston cooperate to form a first chamber; the second stepped hole and the second piston cooperate to form a second chamber; the second stepped hole and the second piston cooperate to form a third chamber; a second air inlet branching off from the air inlet leads to the second chamber; a third air inlet branching off from the air inlet leads to the third chamber; a second guide locking part vertically arranged on the second piston is suitable for blocking the second air inlet; a third guide locking part vertically arranged on the third piston is suitable for blocking the third air inlet.

[0019] In this design, as the valve body thickness gradually decreases during the cleaning process, the piston rod gradually extends. Specifically, gas enters the first chamber through the inlet and acts on the first piston, causing the piston rod to descend. At this time, the second guide locking part blocks the second inlet, and the third guide locking part blocks the third inlet. When the piston rod descends to a certain position, the second guide locking part no longer blocks the second inlet, allowing gas to enter the second chamber through the second inlet. At this point, the gas acts on both the first and second pistons, enabling the piston rod to provide greater downward pressure. Similarly, when the piston rod requires greater downward pressure, the third inlet is not blocked, allowing gas to enter the third chamber and act on the third piston, increasing the downward pressure on the piston rod.

[0020] In order to achieve the reset after the piston is pressed down, the present invention uses a spring between the third piston and the cylinder head, and a spring is sleeved on the piston rod;

[0021] By incorporating a spring, the piston rod can be reset when no gas is introduced into the cylinder.

[0022] To prevent the piston rod from moving to its limit position and potentially damaging the cylinder, this invention employs a vertically installed limit rod on the cylinder head; when the third piston moves downward to its limit position, the limit rod abuts against the third piston, restricting the third piston from continuing to move downward.

[0023] The vertically installed rigid limit rod restricts the further downward movement of the third piston, thus preventing potential damage to the cylinder.

[0024] To illustrate the specific structure of the second guide locking part and the third locking part, the present invention adopts the same structure for the second guide locking part and the third guide locking part, both including: a column body, which matches the inner diameter of the second air inlet or the third air inlet, and a sealing ring is sleeved on its outer wall; a guide member, which is disposed on the top of the column body and located inside the second air inlet or the third air inlet, and an air passage gap is provided between the guide member and the second air inlet or the third air inlet;

[0025] The second and third guide locking parts have the same structure. The bottom of the second and third guide locking parts is a column, the middle is fitted with a sealing ring, and the top is a guide, which can realize both the guiding function and the function of gas passage.

[0026] Specifically, when the column is located in the corresponding air inlet, the air inlet is sealed and not allowed to pass through mainly by the sealing ring. When the second or third piston moves down, the column moves with it and leaves the corresponding air inlet. At this time, the gas enters the next chamber through the ventilation gap. At this time, the guide is still located in the corresponding air inlet. The function of the guide is to prevent the piston rod from rotating.

[0027] Therefore, the second and third guide locking parts serve both a guiding function and a sealing function.

[0028] The beneficial effects of this invention are as follows: This invention is a high-pressure water cleaning rotary clamping device. The bottom of the valve body is supported on a support assembly, which is set on an electric turntable. A clamping assembly is set on the top of the valve body via a column, and the clamping assembly always acts on the top of the valve body, providing a stable clamping force after overcoming the force of the return spring. In this way, the valve body is positioned and locked by the top and bottom supports. The electric turntable rotates, driving the valve body to rotate. Abrasive is added to the high-pressure water, and the valve body on the rotary clamp is cleaned by scanning. Finally, all the shell covering the surface of the product is removed, and the required parts are obtained, thus achieving the cleaning of the valve body. Attached Figure Description

Detailed Implementation

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0036] like Figure 1As shown, the present invention is a high-pressure water cleaning shell rotating clamping device, comprising: a worktable 1; an electric turntable 2 rotatably mounted on the worktable 1; a support assembly mounted on the electric turntable 2, adapted to support the bottom of a valve body 3; a column 4 vertically mounted on the worktable 1; and a clamping assembly 5 fixedly connected to the column 4, located above the valve body 3, adapted to clamp the valve body 3; the bottom of the valve body 3 is placed on the support assembly, and its top is clamped by the clamping assembly 5; the electric turntable 2 rotates, causing the valve body 3 to rotate synchronously.

[0037] In this solution, the bottom of the valve body is supported on a support assembly, which is set on an electric turntable. The clamping assembly is set on the top of the valve body via a column, and the clamping assembly always acts on the top of the valve body. In this way, the valve body is positioned by supporting the top and bottom of the valve body. The electric turntable rotates, which drives the valve body to rotate. Abrasive is added to the high-pressure water, and the valve body on the rotating fixture is cleaned by scanning. Finally, all the shell covering the surface of the product is removed, and the required parts are obtained, thus achieving the cleaning of the valve body.

[0038] Furthermore, in this design, the horizontal section of the column can be adjusted to raise or lower the vertical section, allowing the clamping assembly to be positioned at a suitable height relative to the valve body.

[0039] like Figure 1-2 As shown, in order to illustrate the specific structure of the support component, the present invention adopts a support component including: a sliding groove 6, which is formed on the electric turntable 2; two sliders 71, which are slidably disposed in the sliding groove 6; and a V-shaped support block 7, which is fixedly connected to the corresponding slider 71 and is adapted to support the bottom of the valve body 3.

[0040] Two sliders are slidably set in the sliding groove to accommodate valve bodies of different lengths. The sliders are fixed to the V-shaped support blocks, and the valve body is supported on the two V-shaped support blocks, thus achieving the support of the valve body.

[0041] like Figure 2 As shown, in order to clean the valve body surface as much as possible, the present invention uses an arc-shaped cross-section for the V-shaped support block 7;

[0042] This way, the V-shaped support block makes point contact with the valve body, which helps to clean the surface of the valve body and prevents the support from being left uncleaned.

[0043] like Figure 3 As shown, to illustrate the specific structure of the clamping assembly, the present invention uses a clamping assembly 5 comprising: a cylinder body 8 with an air inlet 9 at its top; a cylinder cover 10 disposed at the bottom of the cylinder body 8; and a piston rod 11 movably disposed within the cylinder body 8, with its end abutting against the valve body 3; gas is introduced into the cylinder body 8 through the air inlet 9, thereby driving the piston rod 11 to move up and down.

[0044] Gas is introduced into the cylinder through the air inlet, which in turn drives the piston rod to move up and down, pressing the end of the piston rod against the top of the valve body to seal and position the top of the valve body.

[0045] like Figure 3 As shown, in order to achieve point contact between the piston rod end and the valve body, the present invention uses a ball 12 at the end of the piston rod 11, and the ball 12 makes point contact with the top of the valve body 3;

[0046] The ball makes point contact with the top of the valve body, which facilitates cleaning of the valve body surface.

[0047] like Figure 3 As shown, to illustrate the specific structure within the cylinder body, the present invention employs a cylinder body 8 with a first stepped hole, a second stepped hole, and a third stepped hole arranged sequentially from top to bottom, each with a gradually increasing cross-section. The piston rod 11 is arranged sequentially from top to bottom with a first piston 13 for sealing the first stepped hole, a second piston 14 for sealing the second stepped hole, and a third piston 15 for sealing the third stepped hole. The first stepped hole and the first piston 13 cooperate to form a first chamber 16; the second stepped hole and the second piston 14 cooperate to form a second chamber 17; the second stepped hole and the second piston 15 cooperate to form a third chamber 18; a second air inlet 19 branching off from the air inlet 9 leads to the second chamber 17; a third air inlet 20 branching off from the air inlet 9 leads to the third chamber 18; a second guide locking part 21, suitable for blocking the second air inlet 19, is vertically arranged on the second piston 14; a third guide locking part 22, suitable for blocking the third air inlet 20, is vertically arranged on the third piston 15.

[0048] In this design, as the valve body thickness gradually decreases during the cleaning process, the piston rod gradually extends. Specifically, gas enters the first chamber through the inlet and acts on the first piston, causing the piston rod to descend. At this time, the second guide locking part blocks the second inlet, and the third guide locking part blocks the third inlet. When the piston rod descends to a certain position, the second guide locking part no longer blocks the second inlet, allowing gas to enter the second chamber through the second inlet. At this point, the gas acts on both the first and second pistons, enabling the piston rod to provide greater downward pressure. Similarly, when the piston rod requires greater downward pressure, the third inlet is not blocked, allowing gas to enter the third chamber and act on the third piston, increasing the downward pressure on the piston rod.

[0049] like Figure 3 As shown, in order to achieve the reset after the piston is pressed down, the present invention uses the third piston 15 and the cylinder head 10, and a spring 23 is sleeved on the piston rod 11;

[0050] By incorporating a spring, the piston rod can be reset when no gas is introduced into the cylinder.

[0051] like Figure 3 As shown, in order to prevent the piston rod from moving to its limit position and causing damage to the cylinder, the present invention uses a limit rod 24 vertically installed on the cylinder head 10; when the third piston 15 moves downward to its limit position, the limit rod 24 abuts against the third piston 15, restricting the third piston 15 from continuing to move downward.

[0052] The vertically installed rigid limit rod restricts the further downward movement of the third piston, thus preventing potential damage to the cylinder.

[0053] like Figure 4 As shown, in order to illustrate the specific structure of the second guide locking part and the third locking part, the present invention adopts the same structure for the second guide locking part 21 and the third guide locking part 22, both including: a column 25, which matches the inner diameter of the second air inlet 19 or the third air inlet 20, and a sealing ring 26 is sleeved on its outer wall; a guide member 27, which is disposed on the top of the column 25 and located inside the second air inlet 19 or the third air inlet 20, and is provided with an air passage gap 28 between it and the second air inlet 19 or the third air inlet 20;

[0054] The second and third guide locking parts have the same structure. The bottom of the second and third guide locking parts is a column, the middle is fitted with a sealing ring, and the top is a guide, which can realize both the guiding function and the function of gas passage.

[0055] Specifically, when the column is located in the corresponding air inlet, the air inlet is sealed and not allowed to pass through mainly by the sealing ring. When the second or third piston moves down, the column moves with it and leaves the corresponding air inlet. At this time, the gas enters the next chamber through the ventilation gap. At this time, the guide is still located in the corresponding air inlet. The function of the guide is to prevent the piston rod from rotating.

[0056] Therefore, the second and third guide locking parts serve both a guiding function and a sealing function.

[0057] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
