Description

Technical Field

[0001] This invention belongs to the field of machining table technology, specifically a valve machining table that can be used for both angular positioning and air blowing. Background Technology

[0002] Valves, as key control components in fluid transport systems, have multiple functions such as regulating flow, pressure, direction, and preventing backflow, and are widely used in petroleum, chemical, water conservancy, and power industries. With the continuous improvement of industrial automation, the requirements for valve processing precision and efficiency are increasing. During valve production, angular positioning is typically required to ensure accurate valve body installation angles. Simultaneously, methods such as air blowing are needed to remove residual cutting fluid, debris, or contaminants from the surface to ensure product quality.

[0003] The existing valve processing equipment is of a single type, which leads to the need for frequent transfer of workpieces of different specifications to different processing tables. When changing fixtures on conventional processing tables, a multi-bolt fixing method is used, which requires ensuring that the force of multiple bolts is the same, which is prone to positioning deviation and is cumbersome to operate, affecting processing accuracy.

[0004] In view of this, a valve processing table that can be used for both angular positioning and air blowing is proposed. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] Given the following technical problems in the existing technology: the existing valve processing equipment is of a single type, which leads to the need for frequent transfer of workpieces of different specifications to different processing tables. When changing fixtures on conventional processing tables, a multi-bolt fixing method is used, which requires ensuring that the force of multiple bolts is the same, which is prone to positioning deviation. Moreover, the operation is relatively cumbersome and affects the processing accuracy.

[0007] To solve the above technical problems, the present invention provides the following technical solution: a valve processing table for both angular positioning and air blowing, comprising a temporary platform, an angular positioning frame, and air blowing protective sheet metal;

[0008] The angular positioning frame and the air-blowing protective sheet metal are respectively installed on the top left and right sides of the temporary platform. The bottom of the angular positioning frame is equipped with a motor, and the output end of the motor is connected to a drive shaft.

[0009] The upper surface of the motor is equipped with a connecting platform, and an operating mechanism is installed on the connecting platform. A connecting mechanism is arranged at the middle position between the connecting platform and the operating mechanism.

[0010] The operating mechanism is hinged to a lower plate at the top;

[0011] The upper surface of the temporary platform is equipped with a temporary fixture located in the air blowing protective sheet metal. The function of the air blowing protective sheet metal is to prevent liquid droplets from splashing during air blowing. The temporary fixture is used to place the workpiece. Several bamboo tubes are installed on the air blowing protective sheet metal, and the direction of air blowing can be manually adjusted by the bamboo tubes.

[0012] The inner edge of the connecting platform is provided with a positioning cylinder, the inner edge of the connecting platform is reserved with a positioning groove, and the inner edge of the connecting platform is provided with a directional column.

[0013] The connecting mechanism consists of a connecting cylinder, a thrust-resistant component, and a flexible ring. The connecting cylinder is clamped inside the connecting platform. A directional mechanism is provided on the part of the connecting cylinder near the positioning cylinder. The directional mechanism limits the position of the connecting cylinder and the connecting platform to prevent the connecting cylinder from rotating after it is connected to the connecting platform. There is a space at the docking point of the connecting cylinder and the connecting platform, and the flexible ring is disposed in this space.

[0014] The operating mechanism consists of a rotary table, a linkage column, and a lifting cylinder. The rotary table docks with the part of the connecting cylinder that is offset from the positioning cylinder. The connecting cylinder and the rotary table are movable. The linkage column passes through the connecting cylinder. The part of the linkage column that extends out of the connecting cylinder contacts the flexible ring. The part of the linkage column that is offset from the flexible ring contacts the lifting cylinder on the rotary table. When the rotary table is rotating, the connecting cylinder is stationary. At this time, the linkage column abuts against the flexible ring to prevent the push-pull parts and the positioning groove from docking.

[0015] As a preferred technical solution for a valve processing table that can be used for both angular positioning and air blowing, an upper plate is installed parallel above the lower plate. An angular positioning fixture is mounted on the upper surface of the upper plate, which is used for placing the valve body. A buffer assembly is configured between the lower plate and the upper plate. When processing larger or heavier parts, the buffer assembly can play a buffering role and reduce wear between the mechanisms. A diffuse reflection photoelectric switch is installed on the upper plate, which is used to detect whether there is a workpiece on the angular positioning fixture.

[0016] As a preferred technical solution for a valve processing table that combines angular positioning and air blowing, the thrusting component is located within a positioning groove and contacts a flexible ring. In this solution, the positioning cylinder is combined with a directional mechanism to ensure precise docking of the connecting cylinder and the connecting platform. The positioning groove provides a certain constraint range for the thrusting component. The partial movement of the thrusting component into the positioning groove limits the position of the connecting cylinder and the connecting platform. The shape of the thrusting component can be set according to requirements. The flexible ring is circular, and there are several thrusting components arranged in a circumferential array, allowing the flexible ring to drive the thrusting components to move together, ensuring a stable docking effect.

[0017] As a preferred technical solution for a valve processing table that can be used for both angular positioning and air blowing, the connecting cylinder has a reserved transmission channel, and the linkage column moves in and out of the transmission channel. The linkage column and the transmission channel have a certain range, which makes the operation smoother and provides enough space for the push-pull parts to retract. The number of the transmission channel, the push-pull parts and the linkage column are configured equally to ensure the consistency of the linkage.

[0018] As a preferred technical solution for a valve processing table that can be used for both angular positioning and air blowing, a speed control table is configured on the inner edge of the connecting cylinder. The speed control table is hinged to the lower plate. A directional opening is milled on the bottom of the speed control table. The directional column is fitted into the directional opening to ensure that the speed control table does not rotate due to the influence of the transmission shaft and to provide stable load for the deceleration mechanism. A deceleration mechanism is configured on the inner edge of the speed control table and the surface of the transmission shaft. The deceleration mechanism is used to reduce the speed of the motor and output a larger torque, which facilitates the mechanism to complete angular positioning.

[0019] As a preferred technical solution for a valve processing table that can be used for both angular positioning and air blowing, the lifting cylinder is located on the inner edge of the connecting cylinder. The part of the lifting cylinder facing the operating mechanism is equipped with a driven chamfer block, and the inner edge of the rotary table is equipped with an active chamfer block. Under normal conditions, the driven chamfer block and the active chamfer block are misaligned. When the driven chamfer block and the active chamfer block are facing each other, they can drive the lifting cylinder to perform telescopic movement. The linkage column contacts the middle circumferential surface of the lifting cylinder. When the rotary table rotates, it can drive the lifting cylinder to perform telescopic movement by relying on the driven chamfer block and the active chamfer block.

[0020] As a preferred technical solution for a valve processing table that can be used for both angular positioning and air blowing, the part of the lifting cylinder near the rotary table is a large-size part, and the part of the lifting cylinder near the connecting table is a small-size part. The two parts are transitioned by a notch and a slope. The notch facilitates the restriction of the linkage column in the normal state, and the slope facilitates the extension and retraction of the lifting cylinder and the linkage column.

[0021] As a preferred technical solution for a valve processing table that can be used for both angular positioning and air blowing, the orientation mechanism consists of orientation stop one and orientation stop two. Orientation stop one is disposed on the side of the positioning cylinder facing the operating mechanism, and orientation stop two is disposed on the side of the connecting cylinder facing the connecting table. Orientation stop one and orientation stop two are staggered and fitted together. After orientation stop one and orientation stop two are fitted together, they limit the state of the connecting cylinder and the connecting table.

[0022] As a preferred technical solution for a valve processing table that can be used for both angular positioning and air blowing, the outer contour of the connecting cylinder is equipped with a shell, and the periphery of the shell is milled with several connecting channels. The number of connecting channels is the same as that of the push-stop parts. The connecting channels allow the push-stop parts to extend and retract in certain positions, and also prevent the push-stop parts from extending out completely.

[0023] As a preferred technical solution for a valve processing table that can be used for both angular positioning and air blowing, the rotary table consists of an outer table and an inner table. The inner table is threaded to the outer contour of the connecting cylinder at a position offset from the connecting table. The outer table is movably assembled to the outer contour of the inner table. By relying on the threaded connection between the inner table and the connecting cylinder, the distance that the active chamfering block moves and the driven chamfering block can be set, which is convenient for application in different situations.

[0024] The beneficial effects of this invention are:

[0025] 1. This angular positioning and air blowing dual-purpose valve processing table, through the design of the connecting mechanism and the operating mechanism, can quickly take out and replace the lower plate of different specifications, significantly improving the switching efficiency and adapting to diverse processing needs;

[0026] 2. This angular positioning and air blowing dual-purpose valve processing table, through the combination of positioning cylinder, orientation mechanism and thrusting parts, ensures precise docking between the connecting cylinder and the connecting table, avoids rotational movement, provides stable position limitation, and improves the overall operational reliability.

[0027] 3. This valve processing table combines angular positioning and air blowing functions, making it convenient for placing, positioning, and air blowing of valve body workpieces, thus improving processing efficiency and versatility.

[0028] 4. This angular positioning and air blowing dual-purpose valve processing table is equipped with a diffuse reflection photoelectric switch, which can detect in real time whether there is a workpiece on the angular positioning fixture, thereby improving the level of automation and processing accuracy.

[0041] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0044] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0045] Example, refer to Figure 1 , 2 3, 4 and 9, a valve processing table for both angular positioning and air blowing, including a temporary platform 10, an angular positioning frame 20 and an air blowing protective sheet metal 30;

[0046] Angle positioning frame 20 and air-blowing protective sheet metal 30 are respectively installed on the top left and right sides of the temporary platform 10. A motor 21 is installed at the bottom of the angle positioning frame 20, and the output end of the motor 21 is connected to a drive shaft 22.

[0047] The upper surface of the motor 21 is equipped with a connecting platform 40, and an operating mechanism 70 is installed on the connecting platform 40. A connecting mechanism 60 is arranged in the middle position between the connecting platform 40 and the operating mechanism 70.

[0048] The operating mechanism 70 is hinged to a lower plate 50, and an upper plate 51 is mounted parallel above the lower plate 50. An angular positioning fixture 52 is mounted on the upper surface of the upper plate 51. The angular positioning fixture 52 is used for placing the valve body. A buffer assembly 53 is arranged between the lower plate 50 and the upper plate 51. When processing large or heavy parts, the buffer assembly 53 can play a buffering role and reduce wear between the mechanisms. A diffuse reflection photoelectric switch 54 is installed on the upper plate 51. The diffuse reflection photoelectric switch 54 is used to detect whether there is a workpiece on the angular positioning fixture 52.

[0049] The upper surface of the temporary platform 10 and located in the air blowing protective sheet metal 30 is equipped with a temporary fixture 31. The function of the air blowing protective sheet metal 30 is to prevent liquid droplets from splashing during air blowing. The temporary fixture 31 is used to place the workpiece. Several bamboo tubes 32 are installed on the air blowing protective sheet metal 30, and the direction of air blowing can be manually adjusted by the bamboo tubes 32.

[0050] Reference Figure 5 and 9 The inner edge of the connecting platform 40 is provided with a positioning cylinder 41, the inner edge of the connecting platform 40 is reserved with a positioning groove 42, and the inner edge of the connecting platform 40 is provided with a directional column 43.

[0051] Reference Figure 5 , 8 9. The connecting mechanism 60 consists of a connecting cylinder 61, a thrusting component 63, and a flexible ring 64. The connecting cylinder 61 is clamped inside the connecting platform 40. A directional mechanism 67 is arranged near the positioning cylinder 41 of the connecting cylinder 61. The directional mechanism 67 limits the position of the connecting cylinder 61 and the connecting platform 40 to prevent the connecting cylinder 61 from rotating after it is connected to the connecting platform 40. There is space at the docking point of the connecting cylinder 61 and the connecting platform 40. The flexible ring 64 is arranged in this space. The thrusting component 63 is located in the positioning groove 42 and contacts the flexible ring 64. In this solution, the positioning cylinder 41 is combined with the directional mechanism 67 to ensure accurate docking of the connecting cylinder 61 and the connecting platform 40. The positioning groove 42 provides a certain constraint range for the thrusting component 63. The partial movement of the thrusting component 63 into the positioning groove 42 can limit the position of the connecting cylinder 61 and the connecting platform 40. The shape of the thrusting component 63 can be set according to requirements.

[0052] The connecting cylinder 61 has a reserved transmission channel 62. The linkage column 74 moves in and out of the transmission channel 62. The linkage column 74 and the transmission channel 62 have a certain range, making the operation smoother and providing enough space for the push part 63 to retract.

[0053] The flexible ring 64 is circular, and there are several anti-push parts 63. The several anti-push parts 63 are arranged in a circular array, so that the flexible ring 64 can drive the several anti-push parts 63 to move together, ensuring the stable effect after docking.

[0054] Reference Figure 6 , 78 and 9, the operating mechanism 70 consists of a rotary table 71, a linkage column 74 and a lifting cylinder 75. The rotary table 71 is connected to the part of the connecting cylinder 61 that is offset from the positioning cylinder 41. The connecting cylinder 61 and the rotary table 71 are movable. The linkage column 74 passes through the connecting cylinder 61. The part of the linkage column 74 that extends out of the connecting cylinder 61 touches the flexible ring 64. The part of the linkage column 74 that is offset from the flexible ring 64 touches the lifting cylinder 75 on the rotary table 71. When the rotary table 71 is rotating, the connecting cylinder 61 is stationary. At this time, the linkage column 74 abuts against the flexible ring 64 so that the push-resistant part 63 and the positioning groove 42 are no longer connected.

[0055] The number of transmission channels 62, thrust components 63, and linkage columns 74 are all equal to ensure the consistency of linkage.

[0056] When the lower plate 50 is switched, the rotary table 71 needs to perform a rotation operation. Under the action of the orientation mechanism 67, the connecting cylinder 61 remains stationary during this process.

[0057] Reference Figure 5 The inner edge of the connecting cylinder 61 is equipped with a speed control platform 65. The bottom of the speed control platform 65 is milled with a directional opening 66. The directional column 43 is fitted into the directional opening 66 to ensure that the speed control platform 65 is not affected by the transmission shaft 22 and to provide stable load for the reduction mechanism. The inner edge of the speed control platform 65 and the surface of the transmission shaft 22 are combined with a reduction mechanism, which is used to reduce the speed of the motor 21, output a larger torque, and facilitate the mechanism to complete angular positioning.

[0058] The above content enables the following: When the lower plate 50 switches to docking, the details are as follows: First, the connecting cylinder 61 is docked into the connecting platform 40. Under the action of the inclined side of the opening of the connecting platform 40, the pushing part 63 will move towards the center of the connecting cylinder 61. At this time, it will squeeze the flexible ring 64 and compress the flexible ring 64. When the connecting cylinder 61 reaches the appropriate position in the connecting platform 40, under the action of the orientation mechanism 67, the state of the connecting cylinder 61 and the connecting platform 40 is limited. This state is a rotation state. Furthermore, under the action of the flexible ring 64, the pushing part 63 will partially correspond to the positioning groove 42 and further limit the two.

[0059] When switching between different specifications of the lower plate 50, the operating mechanism 70 is rotated. The rotary table 71 moves in conjunction with the linkage column 74. Since the linkage column 74 is arranged obliquely downward, at this moment the linkage column 74 pushes the flexible ring 64 in the lower position downward. At this moment, the distance between the upper and lower flexible rings 64 increases. At this moment, the resisting part 63 is no longer subject to the force of the flexible ring 64, and the connecting cylinder 61 can be quickly removed from the connecting table 40, thereby improving the efficiency of switching between different specifications of the lower plate 50.

[0060] When the operating mechanism 70 is rotated, the connecting cylinder 61 will not be linked by the directional mechanism 67, thereby improving the smoothness and reliability of the overall operation.

[0061] Reference Figure 6 and 9 The lifting cylinder 75 is located on the inner edge of the connecting cylinder 61. A driven chamfering block 76 is provided on the part of the lifting cylinder 75 facing the operating mechanism 70. An active chamfering block 77 is provided on the inner edge of the rotary table 71. Under normal conditions, the driven chamfering block 76 and the active chamfering block 77 are misaligned. When the driven chamfering block 76 and the active chamfering block 77 are facing each other, they can drive the lifting cylinder 75 to perform telescopic movement.

[0062] The linkage column 74 contacts the middle circumferential surface of the lifting cylinder 75; when the rotary table 71 rotates, it can link the lifting cylinder 75 to perform telescopic movement by relying on the driven chamfer block 76 and the active chamfer block 77.

[0063] When the lifting cylinder 75 is telescopic, since the upper part of the lifting cylinder 75 is larger than the lower part, the linkage column 74 will move towards the position of the flexible ring 64. Since the linkage column 74 is obliquely arranged, the distance between the pair of flexible rings 64 will increase. At this time, the pushing part 63 is no longer restricted and can leave the positioning groove 42.

[0064] A sliding mechanism can be configured at the contact point between the lifting cylinder 75 and the connecting cylinder 61, so that the lifting cylinder 75 can only move in extension and retraction without being linked to the rotary table 71 to rotate, so that the rotary table 71 can stably drive the lifting cylinder 75 to move in extension and retraction when rotating.

[0065] When the rotary table 71 rotates, several linkage columns 74 are synchronously driven to extend and retract, so that the pushing parts 63 have the same effect on each flexible ring 64.

[0066] The specific steps for removing the restriction on the rotary table 71 and the linkage thrust component 63 are as follows: When the rotary table 71 rotates past the active chamfer block 77 and is aligned with the driven chamfer block 76, it can link the lifting cylinder 75 to perform telescopic movement. Since the upper dimension of the lifting cylinder 75 is larger than the lower dimension, it will link the linkage column 74 to move towards the flexible ring 64. Since the linkage column 74 is obliquely arranged, it will drive the distance between the pair of flexible rings 64 to increase. At this time, the thrust component 63 is no longer restricted and can leave the positioning groove 42. At this time, the connecting cylinder 61 can be quickly and easily removed.

[0067] Reference Figure 9The part of the lifting cylinder 75 near the rotary table 71 is the large part, and the part of the lifting cylinder 75 near the connecting table 40 is the small part. The two parts are connected by a notch and a slope. The notch is convenient for restricting the linkage column 74 in the normal state, and the slope is convenient for the lifting cylinder 75 to drive the linkage column 74 to perform telescopic movement.

[0068] Reference Figure 8 The orientation mechanism 67 consists of orientation stop 68 and orientation stop 69. Orientation stop 68 is located on the side of positioning cylinder 41 facing operating mechanism 70, and orientation stop 69 is located on the side of connecting cylinder 61 facing connecting platform 40. Orientation stop 68 and orientation stop 69 are connected in a staggered fit. After the staggered fit, orientation stop 68 and orientation stop 69 limit the state of connecting cylinder 61 and connecting platform 40.

[0069] After the directional stop 68 is misaligned with the directional stop 68, the positioning cylinder 41 drives the flexible ring 64 to tighten, at which point the pushing part 63 can be applied to the positioning groove 42.

[0070] By relying on directional stop 68 and directional stop 69, the state of connecting cylinder 61 and connecting platform 40 is limited, so that when the lower plate 50 is replaced, the rotary table 71 can rotate independently without causing linkage to the connecting cylinder 61.

[0071] Reference Figure 6 , 7 9. The outer contour of the connecting cylinder 61 is provided with a shell 610. The periphery of the shell 610 is milled with a number of connecting channels 611. The number of connecting channels 611 is the same as that of the thrusting parts 63. The connecting channels 611 can allow a part of the thrusting parts 63 to extend and retract, and can also prevent the thrusting parts 63 from extending out completely.

[0072] The thrusting component 63 is placed on the outer contour of the connecting cylinder 61, and the outer shell 610 is connected to the connecting cylinder 61. This connection method is not limited to threaded connection, etc., to ensure that the thrusting component 63 is located on the inner edge of the connecting channel 611.

[0073] Reference Figure 9 The rotary table 71 consists of an outer table 72 and an inner table 73. The inner table 73 is threaded to the outer contour of the part of the connecting cylinder 61 that is offset from the connecting table 40. The outer table 72 is movably assembled to the outer contour of the inner table 73.

[0074] By relying on the threaded connection between the inner platform 73 and the connecting cylinder 61, the distance that the active chamfering block 77 moves to the driven chamfering block 76 can be set, making it convenient to apply in different situations.

[0075] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0076] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
