Description

Technical Field

[0001] This invention relates to the field of electronic expansion valves, and more specifically to a valve body welding and feeding fixture for the production of electronic expansion valves. Background Technology

[0002] An automatic feeding mechanism for a welding machine, disclosed in application number CN201210410459.X, is applicable to saw blade welding machines. It includes a mounting base with a rotating material tray inside. The rotating material tray is connected to a drive mechanism that rotates it around the mounting base. The rotating material tray includes a tray body and a horizontally extending rim around its outer periphery to form a material conveying edge. A guide component on the rotating material tray guides the material to the rim. The mounting base mates with the rim and has a discharge port for outputting material from the rim. This invention replaces the traditional vibrating tray automatic feeding mechanism, avoiding the constraints imposed on the material trough's transmission by the vibration of the vibrating element. This automatic feeding mechanism is not only simple in structure but also has stable operating performance, avoiding transmission interference caused by vibration, and has broad application prospects.

[0003] In the existing technology, including the aforementioned patent, the valve body still needs to be manually flipped and placed into the placement slot when it is being fed. This feeding process is inefficient and poses a serious safety hazard because manual feeding involves direct contact between personnel and the equipment.

[0004] Therefore, it is necessary to invent a valve body welding and feeding fixture for the production of electronic expansion valves to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a valve body welding and feeding fixture for the production of electronic expansion valves. By realizing the fully automated operation of the valve body from material supply to welding, no manual intervention is required and workers are prevented from contacting exposed moving parts. This solves the problems of low efficiency, high labor intensity and easy injury from moving parts of equipment in the prior art.

[0010] In a preferred embodiment of the present invention, one end of the frame inside the support bridge is connected to the output end of the drive device, the drive device is disposed on the inner side wall of the support bridge, and the drive device is electrically connected to the trigger component.

[0011] The rotating platform is disc-shaped, and a servo motor is connected to the center of the bottom end of the rotating platform. The bottom end of the servo motor is installed in the inner cavity of the support bridge.

[0012] In a preferred embodiment of the present invention, the adjustment assembly includes a connecting frame, the top end of which is connected to the output ends of the two pneumatic push rods, and the bottom end of which is connected to a connecting plate. A sliding groove is provided on the connecting plate, and a distance adjustment plate is provided in the inner cavity of the sliding groove. Two electric telescopic rods are connected to the side wall of the distance adjustment plate, and one end of the two electric telescopic rods is connected to a connecting rod, and one end of the connecting rod is connected to the side wall of the connecting plate.

[0013] In a preferred embodiment of the present invention, one end of the flip motor is bolted to the distance adjustment plate, an annular groove is provided on the outer side wall of the flip motor, a stabilizing rod is rotatably sleeved in the annular groove, a rotating seat is provided at one end of the stabilizing rod, a rotating rod is rotatably connected to the center of the rotating seat, and one end of the rotating rod is connected to the power output shaft of the flip motor.

[0014] In a preferred embodiment of the present invention, the clamping assembly includes a flip plate, one end of which is connected to a rotating rod, and the other end of which is slidably connected to two clamping rods. A servo motor is provided on the side wall of the flip plate, and the power output end of the servo motor is threadedly connected to the clamping rods via a lead screw.

[0015] As a preferred embodiment of the present invention, the arc-shaped bayonet is provided on one end side wall of the clamping rod, and multiple anti-slip grooves are provided on the side wall of the arc-shaped bayonet.

[0016] As a preferred embodiment of the present invention, a plurality of spring telescopic rods are symmetrically arranged on the clamping rod, and a clamping block is provided at the output end of the plurality of spring telescopic rods. The clamping block is L-shaped, and one end of the L-shaped clamping block has an arc-shaped cut surface.

[0017] As a preferred embodiment of the present invention, the guide frame has two guide grooves, the bottom end of the guide groove is provided with a conveyor belt, and a storage box is connected to one side of the conveyor belt.

[0018] The top of the storage box is open, and the inner cavity of the opening of the storage box is provided with a slope. The bottom end of the slope is provided with a discharge port, which corresponds to the position of the guide groove and the conveyor belt.

[0019] As a preferred embodiment of the present invention, the triggering component includes a signal transmitter, one end of which is provided with two telescopic guide rods, and the output ends of the two telescopic guide rods are provided with trigger plates. The cross-section of the trigger plates is arc-shaped, and one side of the trigger plates abuts against the adjacent valve body.

[0020] Compared with the prior art, the technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0021] 1. This equipment conveys the valve body from the storage bin to the outlet via an inner inclined ramp. The conveyor belt then transports it to the guide groove of the guide frame. Once the valve body reaches the bottom, the trigger assembly determines the orientation and transmits a signal based on the contact state of the trigger plate and the extension / retraction of the spring telescopic rod. The flipping device then adjusts its position to align the clamping assembly with the valve body. After the pneumatic push rod moves down, the clamping rod clamps the valve body. When flipping is required, the flipping motor drives the flipping mechanism. The rotating platform delivers the adjusted valve body to the bottom of the welding equipment. The rotating assembly of the placement table fine-tunes the angle to align with the workstation. All of the above processes require no manual intervention, reducing manual operation time and improving work efficiency. Furthermore, workers do not need to directly contact the drive equipment inside the support bridge or the servo motor of the rotating platform, thus avoiding the risk of accidental injury from moving parts and ensuring worker safety.

[0022] 2. This equipment adjusts the distance between the two tilting motors by sliding the distance adjustment plate within the groove of the connecting plate via the electric telescopic rod of the adjustment component. This allows for the adaptation to valve bodies of different widths. The servo motor of the clamping component drives the clamping rod to slide along the tilting plate via a lead screw drive, controlling the opening and closing amplitude. Combined with the arc-shaped bayonet on the clamping rod that matches the shape of the valve body, and the clamping blocks that automatically extend and retract according to the thickness of the valve body, the equipment can stably clamp valve bodies of different heights and diameters. This eliminates the need for frequent component replacements due to changes in valve body specifications, significantly improving the equipment's versatility and flexibility. It also reduces downtime when changing tooling, effectively lowering production adjustment costs. Attached Figure Description

[0044] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] This invention provides, for example Figures 1-10 The above describes a valve body welding and feeding fixture for the production of an electronic expansion valve, which includes a support bridge 1. The inner cavity of the support bridge 1 is provided with a rotating platform 2. The top of the rotating platform 2 is provided with multiple placement platforms 3 arranged in a ring. Each of the multiple placement platforms 3 is provided with two placement slots for placing valve bodies. A rotating component is provided in the placement slots. The head end of the rotating platform 2 is provided with a welding device 4, and the tail end of the rotating platform 2 is provided with a flipping device 5.

[0046] The support bridge 1 provides stable support, and the rotating platform 2 drives the placement table 3 to rotate in a ring, realizing the continuous conveying of the valve body from the flipping device 5 to the welding equipment 4. Multiple placement tables 3 and placement slots can carry multiple valve bodies at the same time. With the help of the rotating components, the valve body angle can be flexibly adjusted, which greatly improves the continuity and efficiency of feeding and welding.

[0047] The flipping device 5 includes:

[0048] Two pneumatic push rods 51 are provided, and both pneumatic push rods 51 are slidably mounted on the side wall of the support bridge 1. An adjustment component 52 is installed at the output end of the two pneumatic push rods 51. Two flip motors 53 are installed on the adjustment component 52. A clamping component 54 is provided at the output end of the two flip motors 53. One end of the clamping component 54 is provided with two arc-shaped bayonets. Multiple spring telescopic rods 55 are provided at the top of the clamping component 54. A guide frame 56 is provided at the bottom of the clamping component 54. A trigger component 57 is provided on the guide frame 56. The trigger component 57 is electrically connected to the spring telescopic rods 55, the flip motors 53, the adjustment component 52, and the rotation component.

[0049] The flipping device 5 achieves vertical lifting adjustment through the pneumatic push rod 51. The adjustment component 52 can flexibly adjust the position of the flipping motor 53. The flipping motor 53 drives the clamping component 54 to complete the flipping action. The arc-shaped bayonet ensures that the valve body is clamped firmly. The spring telescopic rod 55 assists in fixing the valve body. The guide frame 56 guides the valve body conveying direction. The trigger component 57 realizes automatic judgment and linkage control. All components work together to realize the automatic grasping, flipping and positioning of the valve body, reducing manual operation.

[0050] Furthermore, one end of the frame inside the support bridge 1 is connected to the output end of the drive device, the drive device is located on the inner side wall of the support bridge 1, and the drive device is electrically connected to the trigger component 57.

[0051] The drive device inside the support bridge 1 receives the signal from the trigger component 57 and drives the frame to slide, thereby adjusting the lateral position of the flipping device 5, ensuring that the clamping component 54 accurately aligns with the valve body, and improving the automation response speed and positioning accuracy of the equipment.

[0052] The rotating platform 2 is arranged in a disc shape, and a servo motor is connected to the center of the bottom end of the rotating platform 2. The bottom end of the servo motor is installed in the inner cavity of the support bridge 1.

[0053] The disc-shaped rotating platform 2, in conjunction with the bottom servo motor, can achieve stable circular rotation, ensuring that the valve bodies on the placement platform 3 are transported to the welding equipment 4 in sequence, thus improving the stability and accuracy of the transport.

[0054] Furthermore, the adjustment assembly 52 includes a connecting frame 521, the top of which is connected to the output end of two pneumatic push rods 51, and the bottom of which is connected to a connecting plate 522. A sliding groove is provided on the connecting plate 522, and a distance adjustment plate 523 is provided in the inner cavity of the sliding groove. Two electric telescopic rods 524 are connected to the side wall of the distance adjustment plate 523, and one end of the two electric telescopic rods 524 is connected to a connecting rod 525. One end of the connecting rod 525 is connected to the side wall of the connecting plate 522.

[0055] In the adjustment assembly 52, the connecting frame 521 and the pneumatic push rod 51 work together to achieve overall lifting and lowering. The slide groove of the connecting plate 522 provides a sliding track for the distance adjustment plate 523. The electric telescopic rod 524 drives the distance adjustment plate 523 to move through the connecting rod 525, thereby precisely adjusting the distance between the two flip motors 53 to adapt to the clamping requirements of valve bodies of different specifications and enhance the versatility of the equipment.

[0056] Furthermore, one end of the flip motor 53 is bolted to the distance adjustment plate 523. The outer wall of the flip motor 53 is provided with an annular groove, and a rotatable stabilizer 531 is rotatably sleeved in the annular groove. One end of the stabilizer 531 is provided with a rotating seat 532, and a rotating rod 533 is rotatably connected to the center of the rotating seat 532. One end of the rotating rod 533 is connected to the power output shaft of the flip motor 53.

[0057] The flip motor 53 is bolted for easy disassembly and maintenance. The annular groove cooperates with the stabilizer bar 531 to provide stable support when the rotating rod 533 rotates with the flip motor 53, reducing swaying during the flipping process. The rotating seat 532 further improves the rotational stability of the rotating rod 533, ensuring that the valve body flipping action is precise and smooth.

[0058] Furthermore, the clamping assembly 54 includes a flip plate 541, one end of which is connected to the rotating rod 533, and the other end of which is slidably connected to two clamping rods 542. A servo motor 543 is provided on the side wall of the flip plate 541, and the power output end of the servo motor 543 is threadedly connected to the clamping rods 542 through a lead screw.

[0059] In the clamping assembly 54, the flipping plate 541 flips synchronously with the rotating rod 533. The servo motor 543 drives the two clamping rods 542 to slide along the flipping plate 541 through the lead screw, thereby clamping and releasing the valve body. The adjustment is flexible and the clamping force is controllable, ensuring that the valve body is not easy to fall off during the flipping and conveying process.

[0060] Furthermore, an arc-shaped bayonet is provided on one end of the side wall of the clamping rod 542, and multiple anti-slip grooves are provided on the side wall of the arc-shaped bayonet.

[0061] The arc-shaped notch on the clamping rod 542 is adapted to the shape of the valve body, increasing the contact area. Combined with the anti-slip groove, it can increase the friction force, effectively preventing the valve body from slipping during clamping and improving the stability of clamping.

[0062] Furthermore, multiple spring telescopic rods 55 are symmetrically arranged on the clamping rod 542, and each of the multiple spring telescopic rods 55 has a clamping block at its output end. The clamping block is L-shaped, and one end of the L-shaped clamping block has an arc-shaped cut surface.

[0063] The symmetrically arranged spring telescopic rods 55 can automatically extend and retract according to the valve body size. The arc-shaped cut surface of the L-shaped clamping block fits tightly with the valve body, and assists the clamping assembly 54 in fixing the valve body from the side, preventing the valve body from shifting when flipping, and enhancing the reliability of clamping.

[0064] Furthermore, two guide slots are provided on the guide frame 56, and a conveyor belt 58 is provided at the bottom of the guide slots. A storage box 59 is connected to one side of the conveyor belt 58.

[0065] The two guide slots of the guide frame 56 can guide the conveying of two valve bodies at the same time. Together with the conveyor belt 58 at the bottom, the valve bodies are continuously fed. The storage box 59 provides temporary storage space for the valve bodies, ensuring that the feeding process is uninterrupted and improving the feeding efficiency.

[0066] The top of the storage bin 59 is open, and the inner cavity of the opening of the storage bin 59 is provided with a ramp. The bottom of the ramp is provided with a discharge port, which corresponds to the position of the guide groove and the conveyor belt 58.

[0067] The top opening of the storage box 59 facilitates the addition of the valve body. The inner cavity slope uses gravity to make the valve body slide automatically toward the discharge port. The discharge port corresponds to the guide groove and the position of the conveyor belt 58, ensuring that the valve body enters the conveying track smoothly, reducing the frequency of manual feeding and realizing automated feeding.

[0068] Furthermore, the trigger assembly 57 includes a signal transmitter 571, one end of which is provided with two telescopic guide rods 572, and the output end of the two telescopic guide rods 572 is provided with a trigger plate 573. The cross-section of the trigger plate 573 is arc-shaped, and one side of the trigger plate 573 abuts against the adjacent valve body.

[0069] In the trigger assembly 57, when the arc-shaped trigger piece 573 contacts the valve body, it transmits a signal to the signal transmitter 571 through the telescopic guide rod 572. The signal transmitter 571 quickly links other components to adjust their actions, thereby automatically judging the orientation of the valve body, providing a precise basis for subsequent flipping and positioning, and improving the intelligence level of the equipment.

[0070] Working principle:

[0071] Multiple valve bodies are poured into the storage bin 59. The multiple valve bodies accumulate towards the discharge port through the ramp inside the storage bin 59. At this time, the conveyor belt 58 is started. The operation of the conveyor belt 58 transports the valve bodies in the storage bin 59 to the inner cavity of the guide groove on the guide frame 56.

[0072] When the valve body is delivered to the bottom of the guide groove, when the arc-shaped sidewall of the valve body abuts against the trigger plate 573, it can push the telescopic guide rod 572 to retract and squeeze the telescopic guide rod 572. At this time, after the signal transmitter 571 receives the squeeze signal, the drive device in the support bridge 1 pushes the frame and the pneumatic push rod 51 connected to the frame to slide in the support bridge 1. At the same time, the electric telescopic rod 524 drives the distance adjustment plate 523 to adjust the position of the two flip motors 53. When it corresponds to the position of the two valve bodies, the pneumatic push rod 51 pushes the adjustment component 52 to move to the bottom, so that the two clamping rods 542 are located on both sides of the valve body respectively.

[0073] Next, the servo motor 543 drives the two clamping rods 542 to clamp the valve body. Since the clamping rods 542 are provided with two arc-shaped slots, when the needle end of the valve body faces the trigger assembly 57 and is placed in reverse, the height of the needle is higher than the height of the trigger plate 573. Therefore, the trigger plate 573 cannot be pushed to squeeze the telescopic guide rod 572. As a result, the signal transmitter 571 cannot receive the squeezing signal. Therefore, the device can determine that the needle is facing the trigger assembly 57. After clamping the valve body, the device starts the flip motor 53. The power output of the flip motor 53 drives the clamped valve body to flip. Conversely, when the squeezing signal is received, the needle faces the trigger assembly 57 and is lower than the trigger plate 573. The needle can abut against the trigger plate 573, or the arc surface of the valve body abuts against the trigger plate 573 and pushes the trigger plate 573.

[0074] The valve body is then transported to the welding equipment 4 for welding by rotating the rotating platform 2.

[0075] Both of these methods show that the valve body should face upwards, so there is no need to flip it.

[0076] It should be noted that the specific orientation of the valve body can be determined by the extension and retraction of multiple spring telescopic rods 55. When the valve body pin is facing the trigger assembly 57, the two spring telescopic rods 55 near the trigger assembly 57 are in an extended state, and vice versa. Therefore, the valve body orientation can be further accurately determined by working with the trigger assembly 57.

[0077] And through electrical connection, drive the rotating component inside the placement platform 3 to adjust the rotation of the valve body after it is placed;

[0078] After the above operations are completed, the valve body can be automatically fed without manual flipping and rotating during the feeding process, reducing manual labor and improving processing efficiency.

[0079] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
