Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing equipment technology, specifically a turning device for valve production. Background Technology

[0002] Valves are control components in fluid transport systems, with functions such as connecting or disconnecting the flow of media, regulating the flow rate, controlling the pressure of media, and changing the direction of media flow. In the valve manufacturing process, after the metal valve body is cast, it needs to be machined. In the existing technology, when processing valves with intelligent manufacturing equipment, the cast valve is transported to the vicinity of the turning device by a conveying device, and a robot arm is used to place the valve on the conveying device onto the fixture inside the turning device and clamp it. In this process, it is necessary to avoid the robot arm colliding with the cutting tool in the turning device during movement.

[0003] Chinese patent CN113231655B discloses a turning device for valve production. This device is equipped with a mold that can be moved outside the equipment housing. The valve body to be turned can be placed directly on the mold outside the housing. As the mold moves into the housing, the bevel plate and the groove approach each other. The bevel plate pushes the pressure plate down to automatically clamp the valve body.

[0004] The aforementioned device, by setting a movable mold, can avoid the complexity of the robot's movement path, making it easier for the robot to pick up the processed valve and place the valve to be processed onto the mold. However, when the valve body is turned, the connecting parts at both ends of the valve body need to be turned. When using the aforementioned device, since the valve body cannot rotate when it is fixed, after one end of the valve body is processed, the mold needs to be controlled to move outward so that the bevel plate and the groove can be disengaged. Only then can the mold be rotated to drive the valve body to change direction. Then, the mold needs to be moved again to bring the bevel plate and the groove closer together before the other end of the valve body can be turned. This results in low processing efficiency. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a turning device for valve production, which has the functions of clamping the valve body outside the housing and directly rotating and reversing the valve body after it is moved into the housing, thus solving the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] A turning apparatus for valve production includes a housing and a turning assembly. The turning assembly for turning valve bodies is installed inside the housing. The turning assembly has three-dimensional movement capabilities. A translation plate and a machining table are provided inside the housing. The translation plate moves linearly inside the housing to move the machining table between a machining position and a loading position. The machining table is rotatably mounted on the translation plate. A clamping mechanism and a translation control assembly are provided on the machining table.

[0010] The clamping mechanism includes a turntable, a sliding block, a rotating plate, and a mounting plate. The turntable is rotatably connected to the processing table, the sliding block is slidably mounted on the processing table, the rotating plate is rotatably connected to both the turntable and the sliding block, and the mounting plate is fixedly mounted on the sliding block. The mounting plate is also fixedly mounted with a valve body clamp that is adapted to the shape of the valve body.

[0011] When the processing table moves to the material loading position, the translation control component drives the turntable to rotate, causing the sliding block to move the mounting plates away from each other. When the processing table moves to the processing position, the translation control component controls the clamping mechanism to drive the turntable to rotate in the opposite direction, causing the sliding block to move the mounting plates closer to each other. When the processing table rotates freely in the processing position, the turntable rotates synchronously with the processing table.

[0012] Preferably, the clamping mechanism further includes a toothed plate, which is disposed on one side of the turntable and is fixedly installed inside the housing. A toothed ring is fixedly installed on the edge of the turntable. The toothed ring is adapted to mesh with the toothed plate. The toothed plate does not contact the toothed ring when the processing table is in the processing position, and the toothed plate is always in contact with the toothed ring when the processing table is away from the processing position.

[0013] Preferably, the translation control assembly includes a driven plate, a lifting plate, a movable stop, a fixed stop, and a telescopic plug. The driven plate is disposed below the processing table, and a connecting rod is fixedly connected between the driven plate and the processing table. The lifting plate is slidably disposed between the driven plate and the turntable. The movable stop is fixedly mounted on the lifting plate, and the fixed stop is fixedly connected to the driven plate. The telescopic plug is fixedly mounted on the turntable, and the movable end of the telescopic plug is inserted between the movable stop and the fixed stop. A drive motor is fixedly mounted on the translation plate, and the drive end of the drive motor is fixedly connected to the driven plate.

[0014] Preferably, the translation control assembly further includes a return spring and a guide rod. The return spring is fixedly installed between the lifting plate and the driven plate. The guide rod is fixedly installed inside the housing and contacts the upper surface of the lifting plate. The guide rod includes a high horizontal section, an inclined transition section, and a low horizontal section, which are connected in sequence. When the lifting plate slides from the high horizontal section to the low horizontal section, the return spring is compressed, causing the movable stop block to separate from one side wall of the movable end of the telescopic plug.

[0015] Preferably, the telescopic plug includes a sliding sleeve, a slider, and a support spring. The sliding sleeve is fixedly installed on the turntable, the slider is slidably installed inside the sliding sleeve, and a spring groove is provided on the slider. The two ends of the support spring are fixedly connected to the bottom of the spring groove and the lower surface of the turntable, respectively.

[0016] Preferably, the movable stop block has a pressing ramp surface at the end away from the fixed stop block, and the slider has a retraction ramp surface that is adapted to slide with the movable stop block; when the slider approaches the movable stop block, the retraction ramp surface contacts the pressing ramp surface, causing the support spring to be compressed, and the slider pushes the movable stop block away and enters between the movable stop block and the fixed stop block. The space between the movable stop block and the fixed stop block is provided with a receiving groove, and the receiving groove is adapted to be inserted into the slider.

[0017] Preferably, a sliding rod is fixedly connected between the driven plate and the fixed stop, and the lifting plate is slidably connected to the sliding rod.

[0018] Preferably, the translation control component further includes a limiting spring, the two ends of which are rotatably connected to the turntable and the processing table, respectively.

[0019] Preferably, the processing table is provided with a sliding hole and a guide hole, the sliding block is slidably connected to the sliding hole, and the mounting plate is slidably connected to the guide hole.

[0020] Preferably, a guide rod and a cylinder are fixedly installed inside the housing, the translation plate is slidably installed on the guide rod, and the driving end of the cylinder is fixedly connected to the translation plate.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, the present invention provides a turning apparatus for valve production, which has the following advantages:

[0023] 1. This turning device, through the setting of a clamping mechanism and translation control components, automatically releases the valve body clamp when the machining table approaches the loading position, making it easy to remove the valve body that has been turned and place the valve body to be turned onto the valve body clamp. When the machining table approaches the machining position, the valve body clamp automatically clamps, without the need for manual control of clamping. Furthermore, the machining table in the machining position can rotate freely, making it easy to directly rotate the other end to approach the turning component after turning one end of the valve body, thereby enabling more convenient intelligent production and processing of valves.

[0024] 2. This turning device, by setting a driven plate, a lifting plate, a movable stop, a fixed stop, and a telescopic block, ensures that during turning operations, the driving end of the telescopic block is clamped in the middle by the movable and fixed stops, so that the rotating plate is relatively fixed to the machining table. The rotation of the machining table will not affect the clamping effect of the valve body fixture. At the same time, when the machining table moves to the material position, the movable stop moves, causing the driving end of the telescopic block to be released, so that the machined valve body can be easily removed from the valve body fixture.

[0025] 3. This turning device, by setting a toothed plate and a toothed ring, when the machining table moves to the material loading position, the toothed plate and the toothed ring fixed on the rotating plate come into contact, thereby driving the rotating plate to rotate relative to the machining table, so that the valve body clamp is automatically released, which further facilitates the removal and placement of the valve body. At the same time, it also limits the rotation angle between the valve body clamp and the machining table, so that the orientation of the two ends of the valve body clamped between the valve body clamps is controlled when the machining table returns to the machining position.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1

[0046] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The present invention provides a turning device for valve production, including a housing 1 and a turning assembly 7. The turning assembly 7 for turning valve bodies is installed inside the housing 1. The turning assembly 7 has a three-dimensional movement function. The housing 1 is provided with a translation plate 2 and a processing table 3. The translation plate 2 moves linearly inside the housing 1 to move the processing table 3 between a processing position and a loading position. The processing table 3 is rotatably mounted on the translation plate 2. The processing table 3 is provided with a clamping mechanism 4 and a translation control assembly 5.

[0047] The clamping mechanism 4 includes a turntable 41, a sliding block 42, a rotating plate 43, and a mounting plate 44. The turntable 41 is rotatably connected to the processing table 3. The sliding block 42 is slidably mounted on the processing table 3. The rotating plate 43 is rotatably connected to both the turntable 41 and the sliding block 42. The mounting plate 44 is fixedly mounted on the sliding block 42, and a valve body clamp that matches the shape of the valve body is fixedly mounted on the mounting plate 44.

[0048] When the translation control component 5 moves the processing table 3 to the material loading position, it drives the turntable 41 to rotate, causing the sliding block 42 to move the mounting plate 44 away from each other. When the processing table 3 moves to the processing position, the translation control component 5 controls the clamping mechanism 4 to drive the turntable 41 to rotate in the opposite direction, causing the sliding block 42 to move the mounting plate 44 closer to each other. When the processing table 3 rotates freely in the processing position, the turntable 41 rotates synchronously with the processing table 3.

[0049] As can be seen from the above, this turning device, by setting a translation plate 2 that can slide inside the housing 1, allows the machining table 3 to be moved to the opening of the equipment for the replacement of the valve body to be turned. By setting a clamping mechanism 4 and a translation control component 5, the valve body clamp automatically releases when the machining table 3 is close to the loading position, making it easy to remove the valve body that has been turned and place the valve body to be turned onto the valve body clamp. When the machining table 3 is close to the machining position, the valve body clamp automatically clamps without the need for manual control of clamping. Furthermore, the machining table 3 in the machining position can rotate freely, making it easy to directly rotate the other end to be close to the turning component 7 after turning one end of the valve body, thereby improving machining efficiency. The turning component 7 with three-dimensional movement function proposed in this application refers to the common turning structure in the prior art that has up-down, left-right, and forward-backward movement functions and can drive the cutting head to rotate.

[0050] Example 2

[0051] like Figure 3 , Figure 7 , Figure 9 and Figure 10 As shown, the difference between this embodiment and the above embodiment is that the clamping mechanism 4 further includes a toothed plate 45. The toothed plate 45 is disposed on one side of the turntable 41 and is fixedly installed inside the housing 1. A toothed ring 46 is fixedly installed on the edge of the turntable 41. The toothed ring 46 is adapted to mesh with the toothed plate 45. The toothed plate 45 does not contact the toothed ring 46 when the processing table 3 is in the processing position, and the toothed plate 45 is always in contact with the toothed ring 46 when the processing table 3 is away from the processing position.

[0052] As can be seen from the above, when the translation plate 2 moves to the outside of the housing 1, the toothed ring 46 gradually approaches the toothed plate 45. When the translation control component 5 does not control the clamping mechanism 4, the sliding block 42 can slide on the processing table 3. Furthermore, in this embodiment, when the translation plate 2 moves to the outside so that the processing table 3 reaches the loading position, the toothed ring 46 and the toothed plate 45 are still in a meshing state, thereby ensuring that the rotation angle of the turntable 41 is controlled.

[0053] Example 3

[0054] like Figure 5 , Figure 7 , Figure 9 and Figure 10 As shown, the difference between this embodiment and the above embodiment is that the translation control component 5 includes a driven plate 51, a lifting plate 52, a movable stop block 53, a fixed stop block 54, and a telescopic plug 55. The driven plate 51 is disposed below the processing table 3, and a connecting rod 31 is fixedly connected between the driven plate 51 and the processing table 3. The lifting plate 52 is slidably disposed between the driven plate 51 and the turntable 41. The movable stop block 53 is fixedly installed on the lifting plate 52. The fixed stop block 54 is fixedly connected to the driven plate 51. The telescopic plug 55 is fixedly installed on the turntable 41, and the movable end of the telescopic plug 55 is inserted between the movable stop block 53 and the fixed stop block 54.

[0055] As can be seen from the above, since a connecting rod 31 is fixedly connected between the driven plate 51 and the processing table 3, and the lifting plate 52 is slidably disposed between the driven plate 51 and the turntable 41, the driven plate 51 and the processing table 3 are fixed, while the lifting plate 52 can move up and down. When the lifting plate 52 is at the upper end, the movable stop 53 can block the movable end of the telescopic insert 55. When the lifting plate 52 is at the lower end, the movable stop 53 will not block the telescopic insert 55. Specifically, one side wall of the movable stop 53 is connected to the telescopic insert 55. When one side wall of the movable end of the telescopic plug 55 is close to the moving end, the movable end of the telescopic plug 55 cannot disengage from between the movable stop 53 and the fixed stop 54, causing the turntable 41 to rotate with the driven plate 51. When the lifting plate 52 moves, the telescopic plug 55 can disengage from between the movable stop 53 and the fixed stop 54 at the position vacated by the movable stop 53, so that the turntable 41 can rotate relative to the processing table 3 and drive the mounting plate 44 away from each other.

[0056] A drive motor 6 is fixedly installed on the translation plate 2, and the drive end of the drive motor 6 is fixedly connected to the driven plate 51.

[0057] As can be seen from the above, by setting up a drive motor 6 to control the rotation of the processing table 3, it is easier to reverse the valve body and improve processing efficiency.

[0058] The translation control assembly 5 also includes a return spring 56 and a guide rod 57. The return spring 56 is fixedly installed between the lifting plate 52 and the driven plate 51. The guide rod 57 is fixedly installed inside the housing 1 and contacts the upper surface of the lifting plate 52. The guide rod 57 includes a high horizontal part, an inclined transition part and a low horizontal part, which are connected in sequence. When the lifting plate 52 slides from the high horizontal part to the low horizontal part, the return spring 56 is squeezed and compressed, causing the movable stop 53 to separate from one side wall of the movable end of the telescopic plug 55.

[0059] As can be seen from the above, by setting the reset spring 56, since the reset spring 56 can support the lifting plate 52, the movable stop 53 can block the movable end of the telescopic plug 55 when there is no external force interference. When the worktable moves to the material position, the lifting plate 52 is squeezed downward by the guide rod 57, so that the movable stop 53 moves down with it and no longer blocks the telescopic plug 55.

[0060] The telescopic plug 55 includes a sliding sleeve 551, a slider 552, and a support spring 553. The sliding sleeve 551 is fixedly installed on the turntable 41, and the slider 552 is slidably installed inside the sliding sleeve 551. A spring groove is provided on the slider 552, and the two ends of the support spring 553 are fixedly connected to the bottom of the spring groove and the lower surface of the turntable 41, respectively.

[0061] As can be seen from the above, when the lower end of the slider 552 is subjected to pressure, it can compress the support spring 553, causing the slider 552 to move upward a certain distance.

[0062] The movable stop 53 is provided with a pressing ramp 531 at the end away from the fixed stop 54, and the slider 552 is provided with a retraction ramp 554 that is adapted to slide with the movable stop 53. When the slider 552 approaches the movable stop 53, the retraction ramp 554 contacts the pressing ramp 531, which compresses the support spring 553. The slider 552 pushes the movable stop 53 away and enters between the movable stop 53 and the fixed stop 54. A receiving groove is provided between the movable stop 53 and the fixed stop 54, and the receiving groove is adapted to be inserted into the slider 552.

[0063] As can be seen from the above, when the retraction ramp 554 and the extrusion ramp 531 are pressed against each other, the slider 552 is subjected to pressure that causes it to move upward, so that the slider 552 can move upward. Thus, when the turntable 41 rotates, the slider 552 can be inserted between the movable stop 53 and the fixed stop 54. The slider 552 inserted between the movable stop 53 and the fixed stop 54 cannot be dislodged from between the movable stop 53 and the fixed stop 54 if the movable stop 53 does not move downward.

[0064] A slide rod 58 is fixedly connected between the driven plate 51 and the fixed stop block 54, and the lifting plate 52 is slidably connected to the slide rod 58.

[0065] As can be seen from the above, by setting the slide bar 58, on the one hand, it is used to connect the driven plate 51 and the fixed block 54, so that both the driven plate 51 and the fixed block 54 are fixed to the processing table 3. At the same time, it can also guide the lifting plate 52, so that the lifting plate 52 can only move up and down and cannot move horizontally, thereby ensuring that the slider 552 between the movable block 53 and the fixed block 54 cannot push the movable block 53 away.

[0066] The translation control assembly 5 also includes a limit spring 59, the two ends of which are rotatably connected to the turntable 41 and the processing table 3, respectively.

[0067] As can be seen from the above, in this application, when the processing table 3 moves from the processing position to the loading position, the lifting plate 52 should first be pressed down by the guide rod 57, so that the movable stop 53 no longer restricts the movement of the slider 552. Then the toothed ring 46 outside the turntable 41 can mesh with the toothed plate 45 to drive the turntable 41 to rotate. There is a gap between these two structures. By setting the limit spring 59, when the movable stop 53 no longer restricts the movement of the slider 552, the slider 552 is in close contact with one side of the fixed stop 54. The turntable 41 only starts to rotate when the toothed ring 45 and the toothed plate 46 are in contact and mesh. This ensures that when the processing table 3 moves from the processing position to the loading position and then back to the processing position, one end of the clamped valve body to be processed can accurately face the turning assembly 7.

[0068] Example 4

[0069] like Figure 9 and Figure 10 As shown, the difference between this embodiment and the above embodiment is that the processing table 3 is provided with a sliding hole 32 and a guide hole 33, the sliding block 42 is slidably connected to the sliding hole 32, and the mounting plate 44 is slidably connected to the guide hole 33.

[0070] As can be seen from the above, by setting the sliding hole 32 and the guide hole 33, the movement of the mounting plate 44 is made more stable.

[0071] Inside the housing 1, a guide rod 21 and a cylinder 22 are fixedly installed. The translation plate 2 is slidably installed on the guide rod 21, and the driving end of the cylinder 22 is fixedly connected to the translation plate 2.

[0072] As can be seen from the above, by setting guide rod 21 and cylinder 22, the processing table 3 is used to control the translation between the processing position and the loading position.

[0073] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
