Description

Technical Field

[0001] This invention relates to the field of industrial assembly robot technology, and more specifically, to an assembly mechanism for producing pressure testing connectors. Background Technology

[0002] Pressure test fittings are indispensable components in hydraulic, lubrication, and pneumatic pipelines. They are primarily used to quickly connect pressure gauges or sensors during equipment operation to enable pressure detection, venting, or oil sampling without shutting down the system. Their core function lies in the integrated one-way valve structure, which automatically closes the pipeline when the testing equipment is disconnected, preventing media leakage and contaminant intrusion. A typical pressure test fitting usually consists of several precision components, including a fitting body, a metal valve core, a return spring, a sealing gasket, and a retaining ring. Its compact internal structure and assembly precision directly affect the fitting's sealing pressure resistance and service life.

[0003] The use of assembly machines effectively solves the problem of low efficiency in manual assembly. However, during the assembly process, especially with the return spring, its small size and easy deformation cause unstable guiding accuracy when installing it. This often results in the return spring not being on the same axis as the valve core, leading to unstable assembly accuracy and subsequent spring misalignment. This, in turn, causes the sealing steel ball to not fit tightly against the valve body, resulting in weak rebound and leakage of the pressure test connector during use. In addition, sealing rings need to be installed on both ports of the connector body to ensure a seal. However, the ports of the connector body are threaded, and the sealing rings are easily scratched by the sharp edges of the threads when pushed in, seriously affecting the long-term pressure-holding and sealing effect. Furthermore, the direction of the connector body needs to be reversed during assembly, requiring two steps to install the sealing rings on both ports, resulting in an excessive number of assembly steps. Summary of the Invention

[0004] The purpose of this invention is to provide an assembly mechanism for producing pressure testing connectors, so as to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides an assembly mechanism for producing pressure test connectors, comprising: an assembly table, wherein the assembly table is provided with a gripping robot, a positioning part and a guide part, and a bidirectional assembly is installed on the guide part and the assembly table; The gripping robot grabs and delivers the connectors in the incoming material direction to the positioning unit one by one; The assembly platform has through holes corresponding to the bidirectional fitting assembly. The bidirectional fitting assembly passes through the through holes to fit the sealing ring onto the two ports of the connector body without damage. The positioning part includes a rotating ring seat disposed on the assembly table, a plurality of positioning seats circumferentially mounted on the rotating ring seat, each positioning seat having two back plates and an electromagnetic suction plate attached to the back plate, and each pair of electromagnetic suction plates being arranged at an angle. The side of the connector can be attached to the electromagnetic suction plate, and the electromagnetic suction plate generates a suction force to hold the connector tightly when it is energized.

[0006] Furthermore, the bidirectional kit component includes: The first cylinder is mounted downwards on the bottom surface of the assembly table; A vertical arm, which is connected to the output end of the first cylinder; The two cover rings are respectively connected to the vertical arm and the guide part. The two cover rings are fitted with sealing rings. Under the drive of the guide part and the first cylinder, the two cover rings cover the two ports of the connector body respectively. The second cylinder, two sets of the second cylinder are respectively installed on the vertical arm and the guide part; Sliding push rings, the two sliding push rings respectively fit and slide on the two cover rings; A force guide is provided, which connects the sliding push ring to the output end of the second cylinder. When the two sets of the second cylinders are started, the sliding push ring is pushed along the cover ring through the force guide.

[0007] Furthermore, the sliding ring has a cavity containing lubricating fluid, and the side of the sliding ring that is in contact with the cover ring has an annular opening with a hydrophilic layer at the opening. The hydrophilic layer is in contact with the cover ring and the lubricating fluid in the cavity. The cover ring is threadedly connected to the vertical arm and the guide part.

[0008] Furthermore, the guide assembly includes: A support platform, which is disposed on the assembly platform; A swing cylinder, which is mounted on the support platform; A swing platform, which is connected to the output end of the swing cylinder; A cylindrical arm is vertically slidably mounted on the swing platform. One of the two cover rings is threaded to the end of the cylindrical arm. One of the two sets of second cylinders is assembled on the cylindrical arm. After the swing cylinder is activated, the cylindrical arm is swayed to the side above the return spring feeding assembly located on the assembly platform. The third cylinder is mounted downwards on the swing platform, and its output end is connected to the cylinder arm. When the third cylinder is activated, it can push the cylinder arm down to fasten the cylinder arm to the top of the port of the connector body. At this time, the inner cavity of the connector body is connected to the inner cavity of the cylinder arm. An electric push rod, which is inverted and mounted on the inner top surface of the cylinder arm; A guide rod, which is connected to the output shaft of the electric push rod; The bins are embedded in the guide rod and are of different heights and are staggered. An arc panel is connected to several of the compartments. An arc-shaped electromagnetic absorbing plate is attached to the surface of the arc panel. When the cylinder arm swings to the side above the return spring feeding assembly, the electric push rod can be activated to send the guide rod into the return spring on the return spring feeding assembly. At this time, several arc-shaped electromagnetic absorbing plates are attached to the inside of the return spring.

[0009] Furthermore, the chamber includes a frame embedded in the guide rod, a pusher slidably inserted into the frame, at least one spring installed in the frame, the spring being connected to the bottom of the pusher, and an airbag installed in the frame and located behind the pusher. The airbag is connected to an external air pump via a flexible pipe, and a baffle is provided between the airbag and the spring. The arc panel is connected to the end of the pusher.

[0010] Furthermore, a vertical push rod is provided inside the lower cover ring, and the top of the push rod is spherical; The bottom of the guide rod has a conical recess, and the top rod is aligned with the conical recess at the bottom of the guide rod. The electric push rod is connected to the inner top surface of the barrel arm via a ball head.

[0011] Furthermore, the guide section also includes a sealed steel ball feed pipe that is obliquely connected to the cylinder arm; When the boom is fastened to the top of the port of the connector body, the sealing steel ball feed pipe is close to the port of the connector body.

[0012] Furthermore, the back plate and the positioning seat are hinged and have an interference fit.

[0013] Furthermore, a guide tube is connected to the assembly platform, and a soft padding layer is applied to the inner wall of the guide tube; The rotating ring seat rotates, positioning the connector body directly above the guide tube.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention employs a streamlined assembly process, resulting in high assembly efficiency while simultaneously protecting the finished pressure testing connector. Specifically, the guide section precisely assembles the return spring, directly guiding it into the connector body for secure insertion, rather than throwing or allowing it to fall freely. This ensures accurate positioning along the connector body's axis. After assembling the return spring, the guide section immediately inserts a sealing steel ball, thereby guaranteeing that the assembled return spring and the valve core of the connector body are aligned on the same axis with precise and stable assembly accuracy, preventing the return spring from slipping. To prevent misalignment, ensure the sealing steel ball fits tightly against the inside of the valve body, avoiding weak rebound and leakage during use of the pressure testing connector. Simultaneously, by directly crossing the threads on the connector body port using the bidirectional assembly, the sealing ring can be installed onto the roots of both ports of the connector body in one go or sequentially, completing the sealing ring assembly. This effectively prevents the sealing ring from being scratched by the sharp edges of the threads, affecting the long-term pressure-holding and sealing effect. Furthermore, it eliminates the need to rotate the connector body to assemble the sealing rings at both ends individually, simplifying the process, comprehensively improving assembly accuracy, ensuring the sealing pressure resistance and service life of the connector, and increasing assembly efficiency.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0019] like Figures 1-18 As shown, an assembly mechanism for producing pressure test connectors includes: an assembly table 1, on which a gripping robot 2, a positioning part 3 and a guide part 4 are provided, and a bidirectional assembly 5 is installed on the guide part 4 and the assembly table 1. The gripping robot 2 grips and delivers the connectors 6 in the incoming material direction to the positioning unit 3 one by one; The assembly table 1 has through holes corresponding to the bidirectional assembly 5. The bidirectional assembly 5 passes through the through holes to fit the sealing ring onto the two ports of the connector body 6 without damage. The positioning part 3 includes a rotating ring seat 31 set on the assembly table 1, a plurality of positioning seats 32 circumferentially mounted on the rotating ring seat 31, each positioning seat 32 is equipped with two back plates 33, and an electromagnetic suction plate 34 attached to the back plate 33, and each pair of electromagnetic suction plates 34 are arranged at an angle. The side of the connector body 6 can be attached to the electromagnetic chuck 34. When the electromagnetic chuck 34 is energized, it generates a suction force to hold the connector body 6 tightly. During production, the connector body 6, as the main body, is continuously conveyed by feeding methods such as a vibrating feeding tray. The gripping robot 2 grips the connector bodies 6 one by one, straightens their posture, and sends them to the positioning part 3. Since the middle part of the connector body 6 is polygonal, the gripping robot 2 can attach the side of the connector body 6 between two electromagnetic chucks 34. After the connector body 6 is attached to the electromagnetic chuck 34, the electromagnetic chuck 34 is energized to generate a magnetic force to attract the connector body 6, thereby fixing the connector body 6 stably in a vertical state. Then the rotating ring seat 31 rotates to move the fixed connector body 6 away to accept the assembly of the bidirectional assembly 5 and the guide part 4, and then the next set of electromagnetic chucks 34 is turned over. The gripping robot 2 then attaches another connector body 6 between two electromagnetic chucks 34 to achieve a continuous assembly and ensure assembly efficiency. The guide part 4 is used to specifically assemble the return spring, directly guiding it into the connector body 6, rather than throwing or letting it fall freely into the connector body 6. This ensures that the return spring is accurately guided into place along the axis of the connector body 6. After assembling the return spring, the guide part 4 immediately inserts the sealing steel ball, thus ensuring that the assembled return spring and the valve core of the connector body 6 are on the same axis with precise and stable assembly accuracy. This prevents the return spring from shifting and ensures that the sealing steel ball fits tightly with the inside of the valve body, avoiding weak rebound and leakage during use of the pressure test connector. At the same time, the bidirectional fitting assembly 5 directly crosses the threads on the port of the connector body 6, and the sealing ring is installed at the root of the two ports of the connector body 6 in one go or in sequence, completing the assembly of the sealing ring. This effectively avoids the sealing ring being scratched by the sharp edges of the threads, which would affect the long-term pressure-holding and sealing effect. Moreover, it eliminates the need to rotate the connector body 6 to assemble the sealing rings at both ends one by one, simplifying the process, comprehensively improving assembly accuracy, ensuring the sealing pressure resistance and service life of the connector, and improving assembly efficiency.

[0020] Optional, the two-way kit component 5 includes: The first cylinder 51 is mounted downwards on the bottom surface of the assembly table 1; Vertical arm 52 is connected to the output end of the first cylinder 51; Cover ring 53, two cover rings 53 are respectively connected to vertical arm 52 and guide part 4. Sealing rings are arranged on the two cover rings 53. Under the drive of guide part 4 and first cylinder 51, the two cover rings 53 cover the two ports of connector body 6 respectively. The second cylinder 54, the two sets of second cylinders 54 are respectively installed on the vertical arm 52 and the guide part 4; Sliding push rings 55, two sliding push rings 55 respectively fit into the two cover rings 53; The force guide 56 connects the sliding push ring 55 to the output end of the second cylinder 54. When the two sets of second cylinders 54 are started, the sliding push ring 55 is pushed along the cover ring 53 through the force guide 56. When the rotating ring seat 31 rotates the fixed connector body 6, the first cylinder 51 and the guide part 4 are started, pushing the lower cover ring 53 upward and the upper cover ring 53 downward until the two cover rings 53 cover the two ports of the connector body 6 respectively. At this time, the end face of the cover ring 53 reaches the root of the port of the connector body 6. The cover ring 53 is thicker than the port of the connector body 6, so the sealing rings arranged on the cover ring 53 are slightly stretched. At this time, the two sets of second cylinders 54 are started, and the sliding push ring 55 is pushed along the cover ring 53 through the force guide 56, thereby pushing the sealing rings arranged on the cover ring 53. The sealing ring is pushed as a whole, causing it to move until the foremost sealing ring on the cover ring 53 is pushed off the cover ring 53. Once the sealing ring is off the cover ring 53, it will immediately spring back and retract, and then naturally fit onto the root of the port of the connector body 6. The sealing ring is directly fitted onto the root of the two ports of the connector body 6 in one go or one after another, bypassing the threads on the port of the connector body 6. This completely avoids the threads on the port of the connector body 6, preventing the sealing ring from being scratched by the sharp edges of the threads, which would affect the long-term pressure-holding and sealing effect. Moreover, there is no need to rotate the connector body 6 to assemble the sealing rings at both ends one by one. The assembly of the sealing rings at both ends can be completed in the same position, simplifying the process and comprehensively improving the assembly quality, ensuring the sealing pressure resistance and service life of the connector, and improving the assembly efficiency.

[0021] Optionally, the sliding push ring 55 has a cavity containing lubricating fluid. The side of the sliding push ring 55 that is in contact with the cover ring 53 has an annular opening with a hydrophilic layer at the opening. The hydrophilic layer is in contact with the cover ring 53 and the lubricating fluid in the cavity. The hydrophilic layer allows the lubricating fluid stored in the sliding push ring 55 to slowly seep out, thereby applying the lubricating fluid to the cover ring 53 as the sliding push ring 55 moves along the cover ring 53. This greatly improves the lubrication between the cover ring 53 and the sealing rings arranged on it, ensuring that the sliding push ring 55 smoothly pushes the arranged sealing rings and pushes them off the cover ring 53 one by one. This prevents the arranged sealing rings from drying out and stacking under the forced push of the sliding push ring 55, which would affect the smooth progress of the assembly work. The cover ring 53 is threadedly connected to the vertical arm 52 and the guide part 4. When the sealing rings arranged on the cover ring 53 are exhausted, it can be quickly removed and replaced with a new cover ring 53 with sealing rings, ensuring the replacement speed and minimizing the impact on assembly efficiency. Alternatively, the sealing rings can be rearranged and put back on the removed cover ring 53 manually or by a special ring-fitting machine.

[0022] Optionally, the guide unit 4 includes: Support platform 41 is mounted on assembly platform 1; A swing cylinder 42 is mounted on a support platform 41. The swing table 43 is connected to the output end of the swing cylinder 42; The cylinder arm 44 is vertically slidably mounted on the swing platform 43. One of the two cover rings 53 is threaded to the end of the cylinder arm 44. One of the two sets of second cylinders 54 is assembled on the cylinder arm 44. After the swing cylinder 42 is activated, the cylinder arm 44 is swayed to the side above the reset spring feeding assembly located on the assembly platform 1. The third cylinder 45 is mounted on the swing platform 43 facing downwards, and the output end of the third cylinder 45 is connected to the cylinder arm 44. After the third cylinder 45 is started, the cylinder arm 44 can be pushed down to fasten the cylinder arm 44 to the top of the port of the connector body 6. At this time, the inner cavity of the connector body 6 is connected to the inner cavity of the cylinder arm 44. Electric push rod 46 is inverted and mounted on the inner top surface of the boom 44; Guide rod 47 is connected to the output shaft of electric push rod 46; The compartment 48 is embedded in the guide rod 47. The compartments 48 are of different heights and are staggered. The arc panel 49 is connected to several compartments 48. Arc-shaped electromagnetic absorbing plates are attached to the surface of the arc panel 49. When the cylinder arm 44 swings to the side above the return spring feeding assembly, the electric push rod 46 is activated to send the guide rod 47 into the return spring on the return spring feeding assembly. At this time, several arc-shaped electromagnetic absorbing plates are attached to the return spring inside. The third cylinder 45 is activated to slide the cylinder arm 44 downwards on the swing platform 43, which pushes down the cover ring 53 connected to the cylinder arm 44 to cover the port of the connector body 6. Before covering the two ports of the connector body 6 with the cover ring 53, and before rotating the ring seat 31... During the process of rotating the fixed connector body 6, the swing cylinder 42 is activated to swing the swing platform 43 and the cylinder arm 44 toward the side of the return spring receiving assembly on the assembly table 1, so that the guide rod 47 is aligned with the center of the return spring to be picked up at the front of the return spring delivered by the return spring receiving assembly. Then, the cylinder arm 44 remains stationary, and the electric push rod 46 is activated to push the guide rod 47 down, so that it is exposed from the cylinder arm 44 and the cover ring 53 and enters the interior of the return spring delivered by the return spring receiving assembly. At this time, several arc-shaped electromagnetic suction plates are attached to the inner side of the return spring at different heights and angles inside the return spring. Then, several arc-shaped electromagnetic suction plates are applied to the inner side of the return spring. When the electromagnetic chuck is energized, it generates a magnetic force that instantly and synchronously attracts the corresponding part of the return spring, thus pulling the return spring in. Several arc-shaped electromagnetic chucks simultaneously attract the return spring, ensuring that the return spring and the guide rod 47 remain coaxial. Then, the electric push rod 46 resets, pulling the attracted return spring back into the cylinder arm 44. Subsequently, the swing cylinder 42 swings back, resetting the swing platform 43 and the cylinder arm 44, so that the guide rod 47 is realigned with the axis of the connector body 6. At this time, the third cylinder 45 is activated to push down the cover ring 53 to cover the port of the connector body 6. After the cover ring 53 covers the port of the connector body 6, the operation begins. During the installation of the sealing ring, the electric push rod 46 is activated simultaneously to push the retrieved return spring downward into the inner cavity of the connector body 6. After the return spring is in place, the attraction of several arc-shaped electromagnetic chucks to the return spring is disengaged, allowing the return spring to be naturally placed at the center of the inner cavity of the connector body 6. The return spring is steadily guided into the connector body 6 along its axis throughout the process, rather than being thrown or allowed to fall freely into the connector body 6. This ensures precise placement and guarantees that the assembled return spring and the valve core of the connector body 6 are on the same axis, effectively preventing the return spring from shifting.

[0023] Optionally, the chamber 48 includes a frame 481 embedded in the guide rod 47, a pusher 482 slidably inserted in the frame 481, at least one spring 483 installed in the frame 481, the spring 483 being connected to the bottom of the pusher 482, and an airbag 484 installed in the frame 481 and located behind the pusher 482, the airbag 484 being connected to an external air pump through a flexible pipe, and a baffle being provided between the airbag 484 and the spring 483; The arc panel 49 is connected to the end of the push head 482. Before energizing the several arc-shaped electromagnetic absorbing plates to pick up the return spring, air is pumped into the air bag 484 through an external air pump to inflate it, thereby pushing the push head 482 forward. This causes the arc panel 49 to actively move slightly closer to the return spring, allowing the several arc-shaped electromagnetic absorbing plates to better fit with the return spring. This prevents the return spring from falling off due to insufficient suction, and especially prevents the return spring from tilting due to inconsistent suction between the arc-shaped electromagnetic absorbing plates on one side and the arc-shaped electromagnetic absorbing plates on the other side. This ensures that the return spring is installed straight along the axis of the connector body 6 without any offset. On the other hand, it can accommodate return springs of different sizes, ensuring adaptability. After the return spring is guided into place, the air bag 484 deflates. At this time, under the action of the spring 483's rebound pull, the push head 482 can be pulled back slightly, so that the arc-shaped electromagnetic absorbing plates do not contact the return spring. This prevents the arc-shaped electromagnetic absorbing plates from colliding with the return spring and causing it to shift during the upward reset process of the guide rod 47.

[0024] Optionally, a vertical push rod 7 is provided inside the lower cover ring 53, and the top of the push rod 7 is spherical; The bottom of the guide rod 47 has a tapered recess, and the top rod 7 is aligned with the tapered recess at the bottom of the guide rod 47; The electric push rod 46 is connected to the inner top surface of the barrel arm 44 via a ball head. The selected ball head has a certain frictional force, meaning that the electric push rod 46 will not wobble unnecessarily under normal conditions. It can only be moved under a certain external force. The push rod 7, like the guide rod 47, is aligned with the axis of the connector body 6. When the lower cover ring 53 covers the port of the connector body 6, the push rod 7 is inserted into the inner cavity of the connector body 6. As the guide rod 47 moves down, it guides the return spring, and the push rod 7 will mate with the bottom of the guide rod 47. Because it is the spherical top of the push rod 7 that mates with the guide rod... If the bottom of the conical recess of guide rod 47 is not accurately aligned, during the alignment process, the top of the ball of push rod 7 will still be forced into the conical recess at the bottom of guide rod 47. During this process, the fixed push rod 7 exerts a force on guide rod 47 and transmits it to electric push rod 46. Therefore, with the support of the ball head, electric push rod 46 will be forcibly bent and its position will be swung to make push rod 7 accurately align with guide rod 47. This achieves automatic correction if guide rod 47 is skewed, and further ensures that the return spring is installed straight along the axis of connector body 6 without any deviation.

[0025] Optionally, the guide section 4 may also include a sealed steel ball feed pipe 491 that is obliquely connected to the cylinder arm 44; When the cylinder arm 44 is fastened to the top of the port of the connector body 6, the sealing steel ball feed pipe 491 is close to the port of the connector body 6. After the return spring is guided into place and the guide rod 47 is reset, the sealing steel ball feed pipe 491 discharges a sealing steel ball. The sealing steel ball rolls down along the cylinder arm 44 into the connector body 6 and lands on the return spring that has just been placed. After the return spring is installed, the sealing steel ball is installed immediately afterward to prevent the return spring from shifting during operation. This ensures that the sealing steel ball fits tightly with the inside of the valve body and avoids weak rebound and leakage of the pressure testing connector during use.

[0026] Optionally, the back plate 33 and the positioning seat 32 are hinged and have an interference fit. Force can be applied to bend the back plate 33, thereby adjusting the opening angle between the two back plates 33 to accommodate connectors 6 of different sizes.

[0027] Optionally, the assembly table 1 is connected to a guide tube 8, and the inner wall of the guide tube 8 is lined with a soft padding layer. Rotating ring seat 31 rotates, turning connector body 6 to directly above guide tube 8. When rotating ring seat 31 turns the assembled pressure testing connector above guide tube 8, the corresponding two electromagnetic suction plates 34 are de-energized, and the pressure testing connector falls freely into guide tube 8, rolling down along guide tube 8 to the collection point. The soft padding layer inside guide tube 8 provides protection for the pressure testing connector during its rolling process, preventing it from being bumped or damaged.

[0028] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
