Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of valve processing, more particularly, it relates to a factory valve assembly processing equipment. BACKGROUND

[0002] After the valve body casting (valve assembly) obtained by using the lost foam casting process, the valve body needs to be finished, first, the surface is polished, then the interface and the orifice on the valve body are turned and chamfered on the machine tool to remove excess burrs, so as to achieve accurate size and shape, and then drilled to facilitate the installation of accessories and the connection with the pipeline.

[0003] Please refer to Figure 11 , two cross-sectional structure diagrams of existing valve bodies are shown, the pipe orifice of the valve body on the left side is vertically arranged with the interface for installing the valve core, and the pipe orifice of the valve body on the right side is relatively inclinedly arranged with the interface.

[0004] When the existing processing equipment is used to cut the interface and the pipe orifice of the valve body, the cutting tool needs to be kept directly cutting, so that the angle needs to be changed during the processing of a valve body to align each port on it with the cutting tool in turn. However, the included angle between the pipe orifice and the interface of the valve body is not constant, and there are vertical and inclined cases. The vertical case is easy to handle, and the angle can be adjusted from the cutting end or the placement end of the valve body. However, for the inclined case, the existing processing equipment has deficiencies in adjustment and adaptation, and it is difficult to accurately adjust and align, which reduces the processing precision. Moreover, when the included angles of the ports of the valve bodies before and after are inconsistent, the existing processing equipment is difficult to quickly adapt and adjust, and it is difficult to achieve continuous production, so it needs to be improved. SUMMARY

[0005] The present application provides a factory valve assembly processing equipment, which solves the technical problem of the related art that the processing equipment cannot accurately switch when cutting the ports of valve bodies with different orientations.

[0006] The present application provides a factory valve assembly processing equipment, which includes a moving module, a processing module, a valve body clamping module, and a posture switching module.

The central shaft of the worm wheel passes through the turntable and is fixedly connected to the first swing arm. The end of the first swing arm is hinged to the second swing arm, and the second swing arm is fixed to the second rotating shaft through the fisheye connector.

[0008] As a further embodiment of the present invention: the positioning component includes a pointer, an arc-shaped plate, a slide groove, a position sensor, a positioning rod, and a nut. A pointer is fixedly installed at one end of the first rotating shaft. An arc-shaped plate is fixedly installed on the base. A slide groove is formed in the arc-shaped plate. A plurality of position sensors are slidably arranged relative to the slide groove. The position sensors cooperate with the pointer and are electrically connected to the motor. A positioning rod is fixedly installed on the back side of the position sensor. One end of the positioning rod that extends out of the slide groove is threaded, and a nut is fitted on the positioning rod.

[0009] As a further aspect of the present invention: the arc-shaped plate includes a straight portion and an arc-shaped portion, the arc-shaped portion being a quarter-circle arc, and the straight portion extending outward from the end of the arc-shaped portion.

[0010] As a further embodiment of the present invention: the damping component includes a sleeve, a spring, a clamp, a ring, and a rack. A sleeve is fixedly disposed on the end of the first rotating shaft, a clamp is slidably disposed in the sleeve, and a spring is connected between the clamp and the first rotating shaft. A ring is fixedly installed on the base, and racks are equidistantly installed on the inner wall of the ring. The clamp and the rack are in clearance fit.

[0011] As a further embodiment of the present invention: the moving module includes a first base, a first guide rail, a first lead screw, a second base, a second guide rail, and a second lead screw. The first guide rail is symmetrically fixed on the first base, the first lead screw is mounted on the first base, the second base is slidably mounted on the first guide rail, and the second base is configured to cooperate with the output end of the first lead screw. Driven by the first lead screw, the second base slides up and down relative to the first guide rail. The second guide rail is symmetrically fixed on the second base, a processing module is slidably mounted on the second guide rail, and the second lead screw is mounted on the second base. The output end of the second lead screw is configured to cooperate with the processing module. Driven by the second lead screw, the processing module slides left and right relative to the second guide rail.

[0012] As a further aspect of the present invention: the machining module includes a cutting host and a cutting tool, wherein the cutting host has the cutting tool fixed on its output end.

[0013] As a further embodiment of the present invention: the valve body clamping module includes a fixed clamp, a slide rail, a movable clamp, an electric actuator, a traction plate, and a connecting rod. The fixed clamp, the slide rail, and the electric actuator are fixedly mounted on the carrier plate. The movable clamp is slidably mounted on the slide rail. The traction plate is fixedly mounted on the output end of the electric actuator. The connecting rod is fixedly mounted between the traction plate and the movable clamp. The connecting rod slides through the fixed clamp.

[0014] As a further aspect of the present invention, the inner side of the movable clamp is configured as an arc-shaped concave shape.

[0015] As a further aspect of the present invention: the height difference between the center of the worm gear and the ground is greater than the length of the first swing arm.

[0016] The beneficial effects of this invention are as follows: This invention provides a processing method that can handle valve bodies of different styles (with different angles between the pipe openings). When it is necessary to change the orientation of the valve body port during the cutting process, the flipping mechanism is activated to push the second rotating shaft, thereby driving the carrier plate to flip around the base with the first rotating shaft as the center until the new port to be processed is aligned with the output end of the processing module. The positioning component can be set in advance according to the style of the valve body, with the flipping angle and the number of flips set beforehand, without having to check and adjust it during the processing.

[0017] In this invention, the positioning component provides angle control assistance for the flipping mechanism. When the pointer follows the first rotating shaft to align with the position sensor, it transmits a signal to the motor side of the flipping mechanism to stop it and maintain the flipping angle of the carrier plate at this time. This allows each port of the valve body to be processed to be aligned with the cutting part in sequence, achieving automatic adjustment without stopping the machine. This is not only convenient and quick to implement, but also highly accurate, avoiding the drawbacks of inaccurate alignment caused by manual adjustment, which can lead to defects in the cutting process.

[0018] The positioning element in this invention enables the factory valve assembly processing equipment to adapt to more complex working conditions. During continuous processing of different types of valve bodies, the editable adjustment of the position sensors allows for the integration of the processing angle measurement process. Traditional processing equipment, when dealing with this situation, needs to first measure the distribution of the included angles between the ports of the new valve body to be processed, and then adjust the processing angle accordingly, resulting in complex operation logic. However, this application, when dealing with this situation, only requires rearranging the number and angles of the position sensors according to the distribution of the included angles between the ports of the valve body to be processed, eliminating the need for simultaneous adjustment and optimization of the adjustment logic.

[0021] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0022] At least one embodiment of the present invention discloses a valve assembly processing equipment for factory use, such as Figure 1 - Figure 10 As shown, the system includes a moving module 1, a processing module 2, a valve body clamping module 3, and a posture switching module 5. The processing module 2 is fixed to the output end of the moving module 1, and the moving module 1 controls the up-down and left-right movement of the processing module 2. The valve body clamping module 3 is fixed to the output end of the posture switching module 5. The valve body 4 to be processed is detachably mounted relative to the valve body clamping module 3. When the valve body 4 to be processed is fixedly mounted on the valve body clamping module 3, under the action of the posture switching module 5, the valve body 4 to be processed can stop and rotate within the range of 0 to 90 degrees.

[0023] The attitude switching module 5 includes a base 51, a first rotating shaft 52, a carrier plate 53, a second rotating shaft 57, a flipping mechanism 54, a positioning component 55, and a damping component 56. The first rotating shaft 52 is rotatably mounted on one side of the top of the base 51, and the carrier plate 53 is fixed on the first rotating shaft 52. The valve body clamping module 3 is mounted on the carrier plate 53, and the second rotating shaft 57 is fixedly disposed at the bottom of the carrier plate 53. The flipping mechanism 54, which cooperates with the second rotating shaft 57, is disposed in the base 51. Under the action of the flipping mechanism 54, the carrier plate 53 flips relative to the base 51. A positioning component 55, which controls the rotation angle of the carrier plate 53, is disposed on one side of the first rotating shaft 52, and a damping component 56 is fitted at the end of the first rotating shaft 52.

[0024] Unlike existing valve assembly processing equipment, this invention provides a processing method that can handle valve bodies of different styles (with varying angles between pipe openings). When the orientation of the valve body port needs to be changed during the cutting process, the flipping mechanism 54 is activated to push the second rotating shaft 57, thereby driving the carrier plate 53 to flip around the base 51 with the first rotating shaft 52 as the center until the new port to be processed is aligned with the output end of the processing module 2. The positioning component 55 can be set in advance according to the style of the valve body, with the flipping angle and number of flips pre-set, without the need for verification and adjustment during processing. Specifically: The flipping mechanism 54 includes a motor 541, a mounting box 542, a turntable 543, a worm gear 544, a worm wheel 545, a first swing arm 546, a second swing arm 547, and a fisheye connector 548. The mounting box 542 is provided on one side of the motor 541. The turntable 543 is fixedly mounted on the mounting box 542. The worm wheel 545 is rotatably mounted on the back side of the turntable 543. The worm gear 544, which cooperates with the worm gear 544, is fixedly mounted on the output end of the motor 541. The central axis of the worm wheel 545 passes through the turntable 543 and is fixedly connected to the first swing arm 546. The end of the first swing arm 546 is hinged to the second swing arm 547. The second swing arm 547 is fixed to the second rotating shaft 57 through the fisheye connector 548.

[0025] In the flipping mechanism 54, the principle of driving the valve body 4 fixedly loaded on the carrier plate 53 to be processed is as follows: the motor 541 drives the worm 544 to rotate, the worm 544 drives the worm wheel 545 to rotate, the worm wheel 545 drives the coaxial first swing arm 546 to rotate, the rotation of the first swing arm 546 generates a traction effect, which is transmitted to the second rotating shaft 57 through the second swing arm 547 and the fisheye joint 548, thereby pulling the carrier plate 53 to rotate.

[0026] The positioning component 55 includes a pointer 551, an arc plate 552, a slide groove 553, a position sensor 554, a positioning rod 555, and a nut 556. The pointer 551 is fixedly installed at one end of the first rotating shaft 52. The arc plate 552 is fixedly installed on the base 51. The slide groove 553 is opened in the arc plate 552. Several position sensors 554 are slidably arranged relative to the slide groove 553. The position sensors 554 cooperate with the pointer 551 and are electrically connected to the motor 541. The positioning rod 555 is fixedly installed on the back side of the position sensor 554. The end of the positioning rod 555 that extends out of the slide groove 553 is threaded, and the nut 556 is fitted on the positioning rod 555.

[0027] The positioning component 55 provides angle control assistance for the flipping mechanism 54. Specifically, the included angles of each port on the valve body 4 to be processed are calculated in advance. Then, the positions of the position sensors 554 on the arc plate 552 are adjusted to correspond to them and tightened. For example, if the valve body 4 to be processed needs to be cut at 3 ports, and the included angle between adjacent ports is 30 degrees, then 3 sets of position sensors 554 are set in the 90-degree arc range of the arc plate 552. The included angles between the 3 sets of position sensors 554 and the first rotating shaft 52 are 9 degrees respectively. At 0 degrees, 60 degrees, and 30 degrees, when the pointer 551 rotates with the first rotating shaft 52 to align with the position sensor 554, it transmits a signal to the motor 541 side of the flipping mechanism 54, causing it to stop and maintaining the flipping angle of the carrier plate 53 at this time. This allows each port of the valve body 4 to be processed to be aligned with the cutting part in sequence, achieving automatic adjustment without stopping the machine. This is not only convenient and quick to implement, but also highly accurate, avoiding the drawbacks of inaccurate alignment and defects in the cutting process caused by manual adjustment.

[0028] Furthermore, the positioning element 55 enables the factory valve assembly processing equipment of the present invention to adapt to more complex working conditions. When continuously processing different styles of valve bodies 4, the position sensor 554 is editable, allowing the processing angle measurement process to be incorporated. Traditional processing equipment, when dealing with this situation, needs to first measure the distribution of the included angle between the ports of the new valve body 4 to be processed, and then adjust the processing angle accordingly, a complex operational logic involving simultaneous adjustment and adjustment. In contrast, the present application, when dealing with this situation, only needs to adjust the position sensor 554 according to the required angle distribution. The distribution of the included angles between the ports of the processing valve body 4 can be rearranged by adjusting the number and included angles of the position sensors 554. This eliminates the need for adjustments and optimizes the logic for adaptive adjustments. For example, if a new valve body 4 has 4 ports that need to be processed, with included angles of 15 degrees, 20 degrees and 15 degrees respectively, then based on the above, it is only necessary to add one position sensor 554 to the 90-degree arc range of the arc plate 552, and set the included angles between the 4 sets of position sensors 554 and the first rotating shaft 52 to 90 degrees, 75 degrees, 55 degrees and 40 degrees respectively.

[0029] The arc-shaped plate 552 includes a straight section and an arc-shaped section. The arc-shaped section is a quarter-circle arc, and the straight section extends outward from the end of the arc-shaped section.

[0030] The straight section provides temporary storage space for the position sensor 554, which can be placed in the straight section if it is not used during the flipping process.

[0031] After the position sensor 554 completes the included angle adjustment, it needs to be tightened. By rotating the nut 556 relative to the positioning rod 555, the nut 556 presses against the arc plate 552, thus achieving the tightening of the position sensor 554.

[0032] It should be noted that controlling the motor 541 to stop through the sensing action of the position sensor 554 is achievable under the current technology, and the underlying mechanism involved will not be elaborated here.

[0033] In the specific implementation process, due to the dynamic adjustment process, relatively high requirements are placed on maintaining the position of the carrier plate 53. Although the transmission form of the worm gear 545 and worm 544 and the linkage support form of the first swing arm 546 and the second swing arm 547 can provide a certain guarantee for the stability of the carrier plate 53 when it stops, the valve body itself is mostly made of steel and is relatively heavy. In order to enhance the stability in the stopped state, the present invention provides a damping element 56 to provide assistance. Specifically: The damping component 56 includes a sleeve 561, a spring 562, a clamp 563, a ring 564, and a rack 565. A sleeve 561 is fixedly installed on the end of the first rotating shaft 52. A clamp 563 is slidably installed in the sleeve 561, and a spring 562 is connected between the clamp 563 and the first rotating shaft 52. A ring 564 is fixedly installed on the base 51. A rack 565 is installed at equal intervals on the inner wall of the ring 564. The clamp 563 and the rack 565 are in clearance fit.

[0034] In the damping component 56, when the first rotating shaft 52 drives the sleeve 561 to rotate, the chuck 563 will continuously slide in and out of the sleeve 561. The spring 562 deforms and presses in and out of the gap with the rack 565. This provides damping when the first rotating shaft 52 rotates. When the adjustment stops, the first rotating shaft 52 stops rotating, the spring 562 releases and presses the chuck 563 into the gap of the rack 565 to form a limit, thereby enhancing the stability of the carrier plate 53 in the flipping posture at this time.

[0035] The mobile module 1 includes a first base 11, a first guide rail 12, a first lead screw 13, a second base 14, a second guide rail 15, and a second lead screw 16. The first guide rail 12 is symmetrically fixed on the first base 11. The first lead screw 13 is mounted on the first base 11. The second base 14 is slidably mounted on the first guide rail 12. The second base 14 is configured to cooperate with the output end of the first lead screw 13. Driven by the first lead screw 13, the second base 14 slides up and down relative to the first guide rail 12. The second guide rail 15 is symmetrically fixed on the second base 14. A processing module is slidably mounted on the second guide rail 15. The second lead screw 16 is mounted on the second base 14. The output end of the second lead screw 16 is configured to cooperate with the processing module 2. Driven by the second lead screw 16, the processing module 2 slides left and right relative to the second guide rail 15.

[0036] After the posture switching module 5 is used to switch the placement posture of the valve body 4 to be processed, the placement position of the valve body 4 to be processed will be offset in the horizontal and vertical directions. The vertical offset has little impact. The main problem is that the horizontal offset causes the processing module 2 and the various ports of the valve body 4 to be processed to no longer be aligned. To eliminate this adverse effect, the second lead screw 16 drives the processing module 2 fixed on the processing module to move left and right to balance the horizontal displacement deviation caused by the posture switching. The first lead screw 13 controls the inner diameter measuring module to move up and down, which is in coordination with the usage of the processing module 2, driving the processing module 2 to press against the various ports of the valve body 4 to be processed for cutting.

[0037] It should be noted that the linear motion control achieved by the first lead screw 13 and the second lead screw 16 is a mature and existing technology, similar to an XY axis moving platform, so its specific structure will not be elaborated here.

[0038] The machining module 2 includes a cutting host 21 and a cutting tool 22. The cutting host 21 has a cutting tool 22 fixed on its output end. The cutting host 21 drives the cutting tool 22 to rotate at high speed and contact the valve body 4 to be machined for cutting.

[0039] The specific implementation of the cutting host 21 described above can be referred to in the existing technology of lathes, and will not be elaborated here.

[0040] The valve body clamping module 3 includes a fixed clamp 31, a slide rail 32, a movable clamp 33, an electric actuator 34, a traction plate 35, and a connecting rod 36. The fixed clamp 31, the slide rail 32, and the electric actuator 34 are fixedly mounted on the carrier plate 53. The movable clamp 33 is slidably mounted on the slide rail 32. The traction plate 35 is fixedly mounted on the output end of the electric actuator 34. The connecting rod 36 is fixedly mounted between the traction plate 35 and the movable clamp 33. The connecting rod 36 slides through the fixed clamp 31.

[0041] When loading the valve body 4 to be processed, the valve body 4 is placed in the gap between the fixed chuck 31 and the movable chuck 33. Then, the movable chuck 33 is driven to slide relative to the slide rail 32 by the electric push rod 34, so that the movable chuck 33 moves closer to the fixed chuck 31, thereby fixing and clamping the valve body 4 to be processed, waiting for cutting.

[0042] Working principle First, the valve body 4 to be processed is placed in the gap between the fixed chuck 31 and the movable chuck 33. Then, the movable chuck 33 is driven to slide relative to the slide rail 32 by the electric actuator 34, so that the movable chuck 33 moves closer to the fixed chuck 31, thereby fixing and clamping the valve body 4 to be processed, waiting for cutting. After aligning the cutting tool 22 with the tube of the valve body 4 to be processed, the cutting host 21 drives the cutting tool 22 to rotate at high speed, contacting the valve body 4 to be processed for cutting. When it is necessary to change the orientation of the valve body port during the cutting process, the flipping mechanism 54 is activated to push the second rotating shaft 57, thereby driving the carrier plate 53 to flip around the base 51 with the first rotating shaft 52 as the center. The rotation continues until the new port to be processed is aligned with the output end of the processing module 2. The positioning component 55 can be set in advance according to the style of the valve body, with the flipping angle and number of flips set beforehand, without the need to check and adjust during processing. In the flipping mechanism 54, the worm gear 544 is driven to rotate by the motor 541, which in turn drives the worm wheel 545 to rotate. The worm wheel 545 drives the coaxial first swing arm 546 to rotate. The rotation of the first swing arm 546 generates a traction effect, which is transmitted to the second rotating shaft 57 through the second swing arm 547 and the fisheye connector 548, thereby pulling the carrier plate 53 to rotate, so that the new port of the valve body 4 to be processed is aligned with the cutting tool 22.

[0043] The embodiments of the present invention have been described above. However, the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make more equivalent embodiments under the guidance of the present embodiments, and all of them are within the protection scope of the present embodiments.
