Description

Technical Field

[0001] The present invention relates to the technical field of check valve processing, and specifically to an auxiliary processing device for machining the valve port of a safety check valve. Background Art

[0002] A check valve is a valve used to control the unidirectional flow of fluid. It allows the fluid to flow freely in one direction while preventing the fluid from flowing in the opposite direction. It mainly relies on the pressure of the fluid and its own structural design to achieve unidirectional flow control. When the fluid flows in the normal flow direction, the pressure of the fluid overcomes the resistance inside the check valve, causing the valve to open and the fluid to pass through smoothly. When the fluid attempts to flow in the reverse direction, the pressure of the fluid acts on the closing component of the valve, causing it to close tightly and prevent the fluid from flowing in the reverse direction.

[0003] In the field of valve manufacturing, as an important fluid control device, the performance and quality of the check valve are directly related to the safety and stability of industrial production and life. The machining of the valve port of the check valve is a key link in the entire manufacturing process, with extremely high requirements for the accuracy, surface quality, and sealing performance of the valve port.

[0004] The prior art with the publication number CN110936190B provides an auxiliary processing device for machining the valve port of a safety check valve, including side plates, a lead screw, a slide rail, a slider, a sliding plate, a mesh, an auxiliary device, a transmission box, a controller, a power cord, a lock, a handwheel, a driving gear, and a driven gear. In the present invention, an auxiliary device is installed on the top of the sliding plate. The auxiliary device can stably fix the valve port before valve port machining to assist in its completion of machining, and can automatically and stably quickly clean the machined valve port after machining, with strong automation performance and good stability, effectively solving the problems that most cleaning is carried out manually, manual cleaning increases the working steps, resulting in an increase in labor costs, and manual cleaning wastes working time, being time-consuming and laborious.

[0005] In the above prior art, although it can assist in valve port machining and perform rapid cleaning, it does not have the function of reversing the clamped valve. When machining the valve port of the valve, three pipe orifices need to be machined, namely the input and output pipe orifices and the valve orifice for installing the wheel disc handle at the top. Since the directions of the top valve orifice and the input and output pipe orifices are not on the same axis, the existing machining process generally involves separately machining, cutting, and drilling the three valve orifices. After one valve orifice is machined, it is removed from the fixture and then the direction is changed, and the equipment is adjusted to continue machining, which is rather troublesome. In addition, after cutting and grinding, the existing equipment cannot detect the machined valve orifice, and data such as circularity and flatness need to be detected by rotating the valve after removing it from the fixture, which is also troublesome in operation.

[0006] It can be seen that an auxiliary processing device for machining the valve orifice of a safety check valve is needed to solve the problems mentioned in the above background technology, that is, the existing device cannot adjust the clamping direction to assist in turning, and the valve orifice of the valve cannot be immediately detected after machining. Summary of the Invention

The rear side of the side bevel gear is connected to a flat gear through a shaft, and the flat gear is engaged with the gear sleeve.

[0013] The bottom end of the arc handle is connected to a bracket, and a protruding shaft is connected to one side of the bracket. A spring is sleeved at the tail end of the protruding shaft, and a convex block is sleeved in the spring.

By adjusting the distance and height, the detection head is located on one side of the valve port to be detected. Then, by starting the rotating motor and adjusting the rotation of the lead screw, the detection head can draw circles of different sizes to detect different grinding surfaces and mounting holes. The device enables the valve port to be immediately detected after grinding. If the detection data is unqualified, grinding can be continued immediately, ensuring the grinding accuracy and eliminating the need to disassemble the valve from the fixture for detection, making the processes more coherent.

[0023] Third, the present invention realizes that the fixture assembly can control the movement of two groups of clamping blocks by starting the cylinder, thereby clamping the middle valve. The operation is convenient and the clamping is more stable. In cooperation with the bottom plate and the circle-drawing detection assembly, the processing and detection processes of the valve port can be carried out more smoothly.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1 - 7, An auxiliary processing device for machining the valve port of a safety check valve, comprising a bottom plate 1. On one side of the top end of the bottom plate 1, a steering assembly 2 is installed. The steering assembly 2 includes a driving motor 201 and an output shaft 202. On the outer side of the output shaft 202, a worm sleeve 203 and a gear sleeve 204 are provided. A movable sleeve 205 is movably arranged on the outer side of the output shaft 202. On both sides of the movable sleeve 205, it is clamped with the worm sleeve 203 through a first bevel sleeve 2051 and with a connecting block 214 through a second bevel sleeve 2052. An arc handle 206 for controlling its movement is connected to the outer side of the movable sleeve 205. On one side of the gear sleeve 204, a circumferential gear 210 is engaged. The circumferential gear 210 is engaged inside an internal gear 211. The circumferential gear 210 is connected to an outer sleeve 212 through a shaft. One end of the outer sleeve 212 is connected to a mounting plate 213. The mounting plate 213 is penetrated by an inner sleeve shaft 215. One end of the inner sleeve shaft 215 is connected to a first bevel gear 216. A second bevel gear 217 is engaged below the first bevel gear 216. The second bevel gear 217 is connected to a fixture assembly 3 through a shaft in the middle.

[0038] In this embodiment, a controller can be installed in the device. The controller is electrically connected to the electronic components in the device, which is convenient for directly controlling the device. A tool for cutting, grinding or drilling is installed on one side of the device for machining the valve port. The tool can be of the types of tools commonly found on existing machine tools. The existing tool mounting disc can also move, lift and drive the tool to rotate on the machine tool. When the tool is machining the valve port, the circle detection assembly 5 will actively move to other places on the plane and will not block the tool machining. In addition, for this device, the installation direction of the tool is not restricted. Due to the existence of the steering assembly 2 of this device, the tool can be adjusted in angle and cooperate with the machining when installed and machined in different directions.

[0039] Specifically, the output end of the driving motor 201 is connected to a reducer, and the output end of the reducer is connected to an output shaft 202. The output shaft 202 includes a blank shaft and a protruding shaft. The blank shaft and the protruding shaft are integrally formed. The worm sleeve 203 and the gear sleeve 204 are located on the outer side of the blank shaft. The movable sleeve 205 is located on the outer side of the protruding shaft. A groove matching the protrusion is opened inside the movable sleeve 205. The movable sleeve 205 moves on the outer side of the protruding shaft.

[0040] In this embodiment, the reducer at the output end of the driving motor 201 can be a worm and worm gear reducer, which can achieve the purpose of preventing reverse rotation. Moving the adjusting handle 209 left and right is only for adjusting the rotation direction and how to rotate. The ultimate driving force is still the driving motor 201. After the driving motor 201 is started, it drives the output shaft 202 to rotate, and then drives the movable sleeve 205 to rotate. The movable sleeve 205 conveys the rotation to the connecting block 214 or the worm sleeve 203, so as to achieve the rotation purpose of the valve 4. The driving motor 201 can be a servo motor.

[0041] Specifically, the worm gear sleeve 203 and the gear sleeve 204 are respectively arranged on the outer side of the blank shaft through bearings. One side of the worm gear sleeve 203 meshes with a turbine 2031. A lower bevel gear 2032 is connected to the lower part of the turbine 2031 through a shaft. One side of the lower bevel gear 2032 meshes with a side bevel gear 2033. A spur gear 2034 is connected to the rear side of the side bevel gear 2033 through a shaft, and the spur gear 2034 meshes with the gear sleeve 204.

[0042] In this embodiment, when the output shaft 202 rotates, the gear sleeve 204 and the worm gear sleeve 203 on the outer side of the blank shaft do not rotate. Only when the first inclined surface sleeve 2051 enters the interior of the worm gear sleeve 203 can it drive the worm gear sleeve 203 to rotate. Therefore, the length of the bearing installed inside the worm gear sleeve 203 cannot be the same as the length inside the worm gear sleeve 203. The bearing is slightly shorter, and a vacant section is used to connect with the first inclined surface sleeve 2051. A slot structure matching the first inclined surface sleeve 2051 can also be designed inside the worm gear sleeve 203 for driving rotation. Similarly, the second inclined surface sleeve 2052 and the inside of the connecting block 214 can also be provided.

[0043] Specifically, the bottom end of the arc handle 206 is connected to a bracket 207. One side of the bracket 207 is connected to a protruding shaft 2071. The tail end of the protruding shaft 2071 is sleeved with a spring 2072, and a convex block is sleeved in the spring 2072. The protruding shaft 2071 is arranged through a triangular plate at the top of the bottom plate 1. A support plate is arranged on the triangular plate, and the support plate is located above the inner sleeve shaft 215. A stop block 208 is arranged below the bracket 207, and an adjusting handle 209 is arranged at one end of the stop block 208.

[0044] In this embodiment, the moving sleeve 205 can move on the outer side of the protruding shaft of the output shaft 202. When the first inclined surface sleeve 2051 enters the interior of the worm gear sleeve 203, the second inclined surface sleeve 2052 and the connecting block 214 are in a separated state. When the second inclined surface sleeve 2052 contacts the connecting block 214, the worm gear sleeve 203 and the first inclined surface sleeve 2051 are in a separated state, and the two do not coexist. By turning the adjusting handle 209 to drive the stop block 208 to rotate, there are protruding round blocks at the front and rear of the bottom of the bracket 207, and four groups of shaft limiting round blocks are arranged on the stop block 208, so that when the adjusting handle 209 rotates, it will drive the bracket 207 and the arc handle 206 to move through the stop block 208. During processing, the staff can rotate and keep their hand in contact with the adjusting handle 209 to keep it rotating in one direction. A self-locking structure can also be set to lock the adjusting handle 209, so that the adjusting handle 209 will not rotate after the staff releases their hand. In addition, the adjusting handle 209 can be rotated manually by pulling, or can also be rotated electrically or in other ways, which is determined according to the on-site needs.

[0045] Specifically, both the first inclined surface sleeve 2051 and the second inclined surface sleeve 2052 are integrally formed with the moving sleeve 205, and the opening of the first inclined surface sleeve 2051 matches the opening of the worm sleeve 203, and the opening of the second inclined surface sleeve 2052 matches the opening of the connecting block 214.

[0046] In this embodiment, when the worm sleeve 203 rotates, the rotation is transmitted to the gear sleeve 204 through the turbine 2031, the lower bevel gear 2032, the side bevel gear 2033 and the flat gear 2034, rather than directly driving. Because the worm and gear can play a self-locking function, that is, the circumferential gear 210 cannot rotate when the output shaft 202 does not rotate, because the turbine 2031 cannot drive the worm sleeve 203 to rotate, which can make the device run more smoothly during use. The shaft extending from the second bevel gear 217 can be in a "7" - shaped structure.

[0047] Please refer to Figures 8 - 9 , an auxiliary processing device for machining the valve port of a safety check valve. The steering assembly 2 clamps the valve 4 through the fixture assembly 3.

[0048] In this embodiment, the clamping block 307, as the part in contact with the side of the valve 4, can have a different structure from the structure in the drawing. For example, it can be an arc structure. After clamping the valve 4 from both sides, the device can be driven to stably perform processing. The valve to be processed may have a relatively special structure, and the water inlet and the water outlet may not be on the same axis. However, due to the large number of adjustable angles of the steering assembly 2 of this device, the clamped valve 4 is not limited to the shape in the drawing.

[0049] Specifically, the fixture assembly 3 includes a mounting frame 301, and a cylinder 302 is installed at the bottom end of the mounting frame 301. The output end of the cylinder 302 is connected to a vertical plate 303, and inclined slots 304 are symmetrically opened on the vertical plate 303. The inclined slots 304 are penetrated by limit blocks 305, and the limit blocks 305 are located above the mounting frame 301. One side of the limit block 305 is connected to a moving block 306, and a clamping block 307 is arranged on one side of the moving block 306.

[0050] In this embodiment, the controller can be connected to the cylinder 302 to directly control the opening and closing of the cylinder 302. Since the output force of the cylinder 302 is large, the clamping force is also large, which can ensure that the valve 4 is firmly clamped.

[0051] Specifically, a partition is arranged inside the mounting frame 301, and the vertical plate 303 moves up and down on one side of the partition. A slot is opened at the top end of the mounting frame 301, and the vertical plate 303 penetrates through the slot and extends to its outside.

[0052] In this embodiment, two groups of inclined grooves 304 are symmetrically arranged, and both groups of inclined grooves 304 are inclined. The directions of inclination of the two groups of inclined grooves 304 are not necessarily the same as those in the drawings. In the drawings, the distance between the two groups of inclined grooves 304 increases from top to bottom. Therefore, by using the downward pulling method, the two limit blocks 305 can be gradually brought closer, and the distance between the two groups of inclined grooves 304 can also gradually decrease from top to bottom. In this way, the two limit blocks 305 can be gradually brought closer by using the upward pushing method to clamp the valve 4.

[0053] Please refer to Figures 10 - 11 , an auxiliary processing device for machining the valve port of a safety check valve. A circle-drawing detection component 5 for detecting the valve port is arranged on one side of the valve 4. The circle-drawing detection component 5 includes a detection head 501, and the telescopic rod 502 at the bottom end of the detection head 501 is hinged to one side of the lead screw 506. The lead screw 506 is installed on the circular plate 507, and a rotary motor 508 is installed on the rear side of the circular plate 507. The middle part of the telescopic rod 502 is connected to the transverse frame 504.

[0054] In this embodiment, the detection head 501 is detachable from the outer bracket, and the detection head 501 can be replaced according to the detection items. For example, when detecting the flatness of the valve grinding, it can be replaced with a distance sensor or a contact sensor. The sensor is connected to a computer, and the flatness of the valve surface after grinding can be clearly and intuitively observed. Since the diameters of the valve surfaces are different, the size of the drawn circle should also conform to the diameter. The lead screw 506 can be rotated to move the moving block 5061, and the position of the hinge block 505 on one side of the circular plate 507 can be changed. The farther away from the center of the circular plate 507, the larger the diameter of the drawn circle, which is suitable for detecting the valve surface with a larger diameter. The closer to the center of the circular plate 507, the smaller the diameter of the drawn circle.

[0055] Specifically, a bracket is arranged on the outer side of the detection head 501, and the telescopic rod 502 is arranged at the bottom end of the bracket. A short sleeve 503 is arranged in the middle part of the telescopic rod 502. A transverse shaft 5041 penetrates through the transverse frame 504, and a transverse sleeve shaft 5042 is connected to the outer side of the transverse shaft 5041. The transverse sleeve shaft 5042 is connected to the short sleeve 503.

[0056] In this embodiment, the transverse sleeve shaft 5042 is sleeved on the outer side of the transverse shaft 5041 and can move horizontally on the outer side of the transverse shaft 5041. The transverse sleeve shaft 5042 drives the short sleeve 503 to move together. The telescopic rod 502 penetrates through the short sleeve 503 and can lift inside the short sleeve 503. The combination of the horizontal movement track and the lifting track constitutes a circle-drawing track.

[0057] Specifically, the bottom end of the telescopic rod 502 is connected to the hinge block 505, and a hinge shaft is connected to the rear side of the hinge block 505. A moving block 5061 is arranged on the outer side of the lead screw 506, and the moving block 5061 is connected to the hinge block 505 through the hinge shaft.

[0058] In this embodiment, the rotary motor 508 drives the circular plate 507 to rotate at the rear side of the circular plate 507. However, the circular plate 507 and the rotary motor 508 also need to move in a plane following the start of the push rod 509. Therefore, a mobile power source can be installed at the top of the base 5071 at the rear side of the rotary motor 508 to provide electrical energy for the rotary motor 508 so that it can be used normally.

[0059] Specifically, the bottom end of the circular plate 507 is connected to a base 5071. A platform is provided on one side of the top end of the bottom plate 1 away from the steering assembly 2, and a push rod 509 is installed on the platform. The output end of the push rod 509 is connected to a rectangular frame 5091. The number of the push rod 509 and the rectangular frame 5091 is two groups, and the two groups of rectangular frames 5091 converge on the outside of the base 5071.

[0060] In this embodiment, the setting of the platform does not block the flipping and rotation of the valve, and the set position reserves space for the rotation and flipping of the valve. The two groups of push rods 509 are respectively arranged in two axial directions to drive the two groups of rectangular frames 5091 to move. The convergence point of the two groups of rectangular frames 5091 changes with the different extension distances of the push rod 509, so that the base 5071 can be moved to any point on the plane, which is convenient for cooperating with valves at different positions for detection.

[0061] During use, it is necessary to connect to an external power supply, which provides electrical energy for the device so that the device can be used normally. First, start the cylinder 302, causing the cylinder 302 to drive the vertical plate 303 to move downward, so that the limit blocks 305 in the inclined groove 304 move along the inclined direction set by the inclined groove 304. The two groups of limit blocks 305 drive a group of moving blocks 306 and clamping blocks 307 to move respectively. The two groups of clamping blocks 307 move closer to each other to clamp the valve 4 in the middle. After the clamping is stable, the cutting tool on one side can be used to cut and polish the nearest valve port. After the nearest valve port is polished, the other valve port can be polished and cut. The adjusting handle 209 can be turned to the left. The adjusting handle 209 drives the stop block 208 and the bracket 207 to rotate to the left. The bracket 207 drives the arc handle 206 to move to the left, causing the moving sleeve 205 to move to the left, so that the first inclined surface sleeve 2051 enters the inside of the worm sleeve 203 to form a clamping engagement, and drives the worm sleeve 203 to rotate by using the frictional force. The drive motor 201 is started to drive the output shaft 202 to rotate. The output shaft 202 drives the outer moving sleeve 205 to rotate. The moving sleeve 205 drives the worm sleeve 203 to rotate through the first inclined surface sleeve 2051. The rotation of the worm sleeve 203 drives the engaged turbine 2031 to rotate. The turbine 2031 drives the lower bevel gear 2032 to rotate, thereby driving the side bevel gear 2033 on one side to rotate. The side bevel gear 2033 drives the spur gear 2034 to rotate. The spur gear 2034 drives the gear sleeve 204 to rotate through meshing, causing the circumferential gear 210 engaged with it to rotate around the gear sleeve 204 as the center point inside the internal gear 211.The rotation of the circumferential gear 210 drives the rotation of the internal gear 211, the outer sleeve 212 and the mounting plate 213, thereby driving the second bevel gear 217 mounted on one side of the mounting plate 213 to rotate around the first bevel gear 216. The second bevel gear 217 drives the fixture assembly 3 and the valve 4 to rotate through the shaft, and can also drive the adjusting handle 209 to rotate to the right, thereby driving the stopper 208, the bracket 207 and the arc handle 206 to move to the right. The arc handle 206 drives the moving sleeve 205 to move to the right, and the corresponding second inclined sleeve 2052 enters the connecting block 214 to form a snap fit. The connecting block 214 can be driven to rotate by the frictional force. The connecting block 214 drives the inner sleeve shaft 215 and the first bevel gear 216 to rotate. The rotation of the first bevel gear 216 drives the second bevel gear 217 meshing with it to rotate, thereby driving the fixture assembly 3 and the valve 4 to rotate. By moving the adjusting handle 209 left and right in cooperation, the direction of the valve port can be changed at multiple angles, which is convenient for processing valve ports in different directions. After processes such as cutting, grinding, and drilling are completed, the processed valve port can be detected. According to different detection items, the detection head 501 is replaced. By starting the two groups of push rods 509, the base 5071 is driven to move to the position of the corresponding valve port on the platform. Then, according to the aperture or valve surface diameter to be detected, the lead screw 506 is adjusted to move the moving block 5061 on the lead screw 506 to different positions, so that the detection head 501 can draw circles with different diameters. The rotation motor 508 is started, and the rotation motor 508 drives the entire circular plate 507 to rotate, thereby driving the entire lead screw 506 to rotate. Through the hinge, the hinge block 505 is driven to perform a certain action. After this action is restricted by the transverse frame 504, it acts on the detection head 501, thereby realizing circle drawing. The clamped valve 4 cannot rotate for detection. The detection head 501 moves on the specified hole or valve surface for detection. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.,
