Description

Technical Field

[0001] The invention relates to the technical field of check valve processing, in particular to auxiliary processing equipment for processing a valve port of a safety check valve. Background Art

[0002] A check valve is a valve used to control the one-way flow of fluid. It allows the fluid to flow freely in one direction, but blocks the flow of fluid in the opposite direction. It mainly relies on the pressure of the fluid and its own structural design to achieve one-way 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 smoothly. When the fluid tries to flow in the opposite direction, the pressure of the fluid acts on the closing part of the valve, causing it to close tightly and preventing the fluid from flowing in the opposite direction.

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

[0004] The prior art publication number is CN110936190B, which provides an auxiliary processing equipment for processing the valve port of a safety check valve, including a side plate, a screw rod, a slide rail, a slider, a sliding plate, a partition net, an auxiliary device, a transmission box, a controller, a power cord, a lock, a hand wheel, a driving gear and a driven gear. The present invention installs an auxiliary device on the top of the sliding plate, and the auxiliary device can stably fix the valve port before the valve port is processed to assist in completing the processing, and can automatically and stably clean the processed valve port quickly after processing. It has strong automation performance and good stability, and effectively solves the problems of mostly manual cleaning, manual cleaning, increased work steps, increased labor costs, and manual cleaning wastes working time and is time-consuming and labor-intensive.

[0005] Although the above-mentioned prior art can assist in valve port processing and perform quick cleaning, it does not have the function of reversing the clamped valve. When processing the valve port, it is necessary to process three pipe ports, the input and output pipe ports, and the valve port with a wheel handle installed on the top. Because the directions of the top valve port and the input and output pipe ports are not on the same axis, all existing processing processes generally involve cutting and drilling the three valve ports separately. After a valve port is processed, it is removed from the fixture and then the direction is changed, and the equipment is adjusted to continue processing. The operation is relatively cumbersome. In addition, after cutting and grinding, the existing equipment cannot detect the processed valve port. The circularity, flatness and other data require the valve to be taken out of the fixture and then rotated for detection, which is cumbersome to operate.

[0006] It can be seen that an auxiliary processing equipment for processing the valve port of a safety check valve is needed to solve the problems mentioned in the above background technology that the existing equipment cannot adjust the clamping direction to assist in turning and the valve port cannot be inspected immediately after processing.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 7A processing device for auxiliary processing of a safety check valve port, comprising a bottom plate 1, a steering assembly 2 is installed on one side of the top of the bottom plate 1, the steering assembly 2 comprises a driving motor 201 and an output shaft 202, and a worm sleeve 203 and a gear sleeve 204 are arranged on the outer side of the output shaft 202, a movable sleeve 205 is movable on the outer side of the output shaft 202, and both sides of the movable sleeve 205 are respectively clamped with the worm sleeve 203 through a first bevel sleeve 2051, and clamped with a connecting block 214 through a second bevel sleeve 2052, and the outer side of the movable sleeve 205 It is connected to an arc handle 206 for controlling its movement, one side of the gear sleeve 204 meshes with the circumferential gear 210, and the circumferential gear 210 meshes inside the internal gear 211, the circumferential gear 210 is connected to the outer sleeve 212 through a shaft, and one end of the outer sleeve 212 is connected to the mounting plate 213, the mounting plate 213 is penetrated by the inner sleeve shaft 215, and one end of the inner sleeve shaft 215 is connected to the first bevel gear 216, the second bevel gear 217 meshes below the first bevel gear 216, and the middle of the second bevel gear 217 is connected to the clamp assembly 3 through a shaft.

[0025] In this embodiment, a controller can be installed in the device, and the controller is electrically connected to the electronic components in the device to facilitate direct control of the device. A tool for cutting, grinding or drilling is installed on one side of the device to process the valve port. The tool can be a common type of tool on existing machine tools. The existing tool mounting plate can also be moved, raised and lowered on the machine tool, and drive the tool to rotate. When the tool processes the valve port, the circle drawing detection component 5 will actively move to other places on the plane and will not block the tool processing. In addition, for this device, the direction of tool installation is not limited. Because of the presence of the steering component 2 of the device, the tool can be installed and processed in different directions, and the angle can be adjusted to cooperate with the processing.

[0026] 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, and the output shaft 202 includes a blank shaft and a raised shaft, the blank shaft and the raised shaft are integrally formed, and the worm sleeve 203 and the gear sleeve 204 are located on the outside of the blank shaft, the movable sleeve 205 is located on the outside of the raised shaft, and a groove matching the raised shaft is provided inside the movable sleeve 205, and the movable sleeve 205 moves on the outside of the raised shaft.

[0027] In this embodiment, the reducer at the output end of the driving motor 201 can be a worm gear reducer, which can prevent reversal. Moving the adjustment handle 209 left and right is only for adjusting the direction of rotation and how to rotate. The final 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 transmits the rotation to the connecting block 214 or the worm sleeve 203, thereby achieving the purpose of rotating the valve 4. The driving motor 201 can be a servo motor.

[0028] Specifically, the worm sleeve 203 and the gear sleeve 204 are respectively arranged on the outside of the blank shaft through bearings, and a turbine 2031 is meshed on one side of the worm sleeve 203, a lower bevel gear 2032 is connected to the lower part of the turbine 2031 through a shaft, and one side of the lower bevel gear 2032 is meshed with a side bevel gear 2033, and a flat gear 2034 is connected to the rear side of the side bevel gear 2033 through a shaft, and the flat gear 2034 is meshed with the gear sleeve 204.

[0029] In this embodiment, when the output shaft 202 rotates, the gear sleeve 204 and the worm sleeve 203 on the outside of the blank shaft will not rotate. Only when the first bevel sleeve 2051 enters the inside of the worm sleeve 203 will the worm sleeve 203 be driven to rotate. Therefore, the length of the bearing installed inside the worm sleeve 203 cannot be the same as the inside of the worm sleeve 203. The bearing is slightly shorter, and the empty section is used to connect with the first bevel sleeve 2051. The interior of the worm sleeve 203 can also be designed with a slot structure that matches the first bevel sleeve 2051 for driving rotation. Similarly, the interior of the second bevel sleeve 2052 and the connecting block 214 can also be set.

[0030] Specifically, the bottom end of the arc handle 206 is connected to a bracket 207, and 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 protrusion is sleeved in the spring 2072, the protruding shaft 2071 passes through a triangular plate arranged 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 adjustment handle 209 is arranged at one end of the stop block 208.

[0031] In this embodiment, the movable sleeve 205 can move outside the raised shaft of the output shaft 202. When the first bevel sleeve 2051 enters the interior of the worm sleeve 203, the second bevel sleeve 2052 and the connecting block 214 are in a disengaged state. When the second bevel sleeve 2052 and the connecting block 214 are in contact, the worm sleeve 203 and the first bevel sleeve 2051 are in a disengaged state, and the two will not coexist. By turning the adjusting handle 209, the stopper 208 is driven to rotate. The bottom of the bracket 207 is provided with protruding round blocks at the front and rear. The stopper 208 is Four sets of axis limiting blocks are provided, so that when the adjusting handle 209 is rotated, the bracket 207 and the arc handle 206 will be driven to move through the block 208. During processing, the staff can rotate the adjusting handle 209 and keep it in contact with the hand to keep it rotating in one direction. A self-locking structure can also be provided to self-lock the adjusting handle 209, so that the adjusting handle 209 will not rotate after the staff lets go. In addition, the adjusting handle 209 can be manually turned, or it can be rotated by electric or other means, depending on the needs on site.

[0032] Specifically, the first bevel sleeve 2051 and the second bevel sleeve 2052 are both integrally formed with the movable sleeve 205 , and the first bevel sleeve 2051 matches with the opening of the worm sleeve 203 , and the second bevel sleeve 2052 matches with the opening of the connecting block 214 .

[0033] 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, and is not directly driven, because the worm and turbine 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 smoother during use. The shaft extending from the second bevel gear 217 can be a "7" shaped structure.

[0034] See also Figure 8-Figure 9 , an auxiliary processing equipment for processing the valve port of a safety check valve, a steering component 2 clamps a valve 4 through a clamp component 3.

[0035] In this embodiment, the clamp block 307, as a part in contact with the side of the valve 4, may be different from the structure shown in the attached figure, for example, it may be an arc structure, and after the valve 4 is clamped from both sides, the device can be driven to perform processing stably. The valve to be processed may be a relatively special structure, and the water inlet and outlet may not be located on the same axis. However, since the steering assembly 2 of the device has many adjustable angles, the clamped valve 4 is not limited to the shape shown in the attached figure.

[0036] Specifically, the clamp 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 the vertical plate 303 is symmetrically provided with inclined grooves 304, the inclined grooves 304 are penetrated by a limit block 305, and the limit block 305 is located above the mounting frame 301, a moving block 306 is connected to one side of the limit block 305, and a clamping block 307 is provided on one side of the moving block 306.

[0037] In this embodiment, the controller can be connected to the cylinder 302 to directly control the opening and closing of the cylinder 302. The output force of the cylinder 302 is large, so the clamping force is also large, which can ensure that the valve 4 is firmly clamped.

[0038] Specifically, a partition is disposed inside the mounting frame 301 , and the vertical plate 303 is raised and lowered on one side of the partition. A slot is provided at the top of the mounting frame 301 , and the vertical plate 303 passes through the slot and extends to the outside thereof.

[0039] In this embodiment, the two groups of inclined grooves 304 are symmetrically arranged, and the two groups of inclined grooves 304 are both inclined. The inclination direction of the two groups of inclined grooves 304 is not necessarily the same as that in the attached drawings. In the attached drawings, the distance between the two groups of inclined grooves 304 increases from top to bottom, so the two groups of limit blocks 305 are gradually approached by pulling down, and the distance between the two groups of inclined grooves 304 can also be gradually reduced from top to bottom. In this way, the two groups of limit blocks 305 can be gradually approached by pushing up to clamp the valve 4.

[0040] See also Figure 10-11 , an auxiliary processing equipment for processing 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 a telescopic rod 502 at the bottom end of the detection head 501 is hinged on one side of a screw rod 506, the screw rod 506 is installed on a circular plate 507, and a rotating motor 508 is installed on the rear side of the circular plate 507, and the middle part of the telescopic rod 502 is connected to the horizontal frame 504.

[0041] In this embodiment, the detection head 501 and the outer bracket are detachable, and the detection head 501 can be replaced according to the detection items. For example, it can be replaced with a distance sensor or a contact sensor to detect the flatness of the valve polishing. The sensor is connected to the computer, and the flatness of the valve surface after polishing can be clearly and intuitively observed. Since the valve surface diameters are different, the size of the circle must also conform to the diameter. The screw rod 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 circle is, which is suitable for the detection of valve surfaces with larger diameters. The closer to the center of the circular plate 507, the smaller the diameter of the circle is.

[0042] Specifically, a bracket is provided on the outside of the detection head 501, and the telescopic rod 502 is provided at the bottom end of the bracket, a short sleeve 503 is provided in the middle part of the telescopic rod 502, a transverse axis 5041 passes through the transverse frame 504, and a transverse sleeve axis 5042 is connected to the outside of the transverse axis 5041, and the transverse sleeve axis 5042 is connected to the short sleeve 503.

[0043] In this embodiment, the transverse sleeve shaft 5042 is sleeved on the outside of the transverse shaft 5041 and can move laterally on the outside of the transverse shaft 5041. The transverse sleeve shaft 5042 drives the short sleeve 503 to move together. The telescopic rod 502 passes through the short sleeve 503 and can be raised and lowered inside the short sleeve 503. The transverse movement trajectory and the lifting trajectory are combined to form a circular trajectory.

[0044] Specifically, the bottom end of the telescopic rod 502 is connected to the articulated block 505 , and the rear side of the articulated block 505 is connected to a hinge shaft, a moving block 5061 is arranged outside the screw rod 506 , and the moving block 5061 is connected to the articulated block 505 via the hinge shaft.

[0045] In this embodiment, the rotating motor 508 drives the circular plate 507 to rotate at the rear side of the circular plate 507, but the circular plate 507 and the rotating motor 508 also need to move in a plane following the start of the push rod 509, so a mobile power supply can be installed at the top of the base 5071 at the rear side of the rotating motor 508 to provide power for the rotating motor 508 so that it can be used normally.

[0046] Specifically, the bottom end of the circular plate 507 is connected to a base 5071, a platform is provided on the top side of the bottom plate 1 away from the steering assembly 2, and a push rod 509 is installed on the platform, and the output end of the push rod 509 is connected to a rectangular frame 5091, and the number of push rods 509 and rectangular frames 5091 are both two groups, and the two groups of rectangular frames 5091 are gathered on the outside of the base 5071.

[0047] In this embodiment, the setting of the platform does not block the flipping and rotation of the valve. The setting position reserves space for the rotation and flipping of the valve. The two groups of push rods 509 are respectively set on two axes, driving the two groups of rectangular frames 5091 to move. The gathering point of the two groups of rectangular frames 5091 changes with the extension distance of the push rods 509, so that the base 5071 can be moved to any point on the plane, which is convenient for detection of valves in different positions.

[0048] When in use, it is necessary to connect an external power supply, which provides electrical energy for the device so that the device can be used normally. First, start the cylinder 302, so that the cylinder 302 drives the vertical plate 303 to move downward, so that the limit block 305 located in the inclined groove 304 moves according to the inclined direction set by the inclined groove 304, and the two groups of limit blocks 305 respectively drive a group of moving blocks 306 and clamping blocks 307 to move. The two groups of clamping blocks 307 are close to each other to clamp the valve 4 located in the middle. After the clamping is firm, the cutting tool on one side can be used to cut and grind the nearest valve port. When the nearest valve port is polished, the other valve ports can be polished and cut. The adjusting handle 209 can be turned to the left, and the adjusting handle 209 drives the stopper 208 and the bracket 207 to rotate to the left. The bracket 207 drives the arc handle 206 to move to the left, so that the moving sleeve 205 moves to the left, so that the first bevel sleeve 2051 enters the worm sleeve 203 The worm sleeve 203 is rotated by friction force, the driving motor 201 is started to drive the output shaft 202 to rotate, the output shaft 202 drives the outer movable sleeve 205 to rotate, the movable sleeve 205 drives the worm sleeve 203 to rotate through the first bevel sleeve 2051, the rotation of the worm sleeve 203 drives the meshing 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 flat gear 2034 to rotate, the flat gear 2034 drives the gear sleeve 204 to rotate through meshing, so that the circumferential gear 210 meshing with it rotates inside the internal gear 211 with the gear sleeve 204 as the center point,The rotation of the circumferential gear 210 drives the internal gear 211, the outer sleeve 212 and the mounting plate 213 to rotate, thereby driving the second bevel gear 217 installed 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 rightward, thereby driving the stopper 208, the bracket 207 and the arc handle 206 to move rightward, and the arc handle 206 drives the movable sleeve 205 to move rightward. The second bevel sleeve 2052 enters the connecting block 214 correspondingly to form a card and the connecting block 214 can be driven to rotate by friction. 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 will drive the second bevel gear 217 meshing therewith to rotate, thereby driving the fixture assembly 3 and the valve 4 to rotate.
