Description

Technical Field

[0001] This utility model relates to the field of riveting technology for copper pipe joints of oil inlet valves, specifically, to an oil inlet valve riveting fixture and an oil inlet valve joint assembly. Background Technology

[0002] An inlet valve copper pipe fitting is a connecting component used in liquid or gas pipeline systems, primarily in automotive, machinery, and industrial pipelines. Its main function is to connect copper pipes to other fittings or valves to ensure smooth fluid flow throughout the system.

[0003] Riveting is a method of tightly joining two or more components by using rivets or other fasteners at key points of the joint to secure them together. Riveting fixtures are typically designed to precisely position copper tubing and joints to ensure accuracy.

[0004] The copper tube of the oil inlet valve connector usually needs to be machined into a flared shape to facilitate fixing the copper tube inside the oil inlet valve connector, such as... Figure 2 As shown.

[0005] Therefore, the present invention urgently needs to solve the problem of providing an oil inlet valve riveting clamp and an oil inlet valve connector assembly that can process copper pipes into a trumpet shape so that users can fix copper pipes in the oil inlet valve connector. Utility Model Content

[0006] To address the aforementioned technical problems, the purpose of this utility model is to overcome the fact that in the prior art, the copper tube of the oil inlet valve connector usually needs to be processed into a trumpet shape, thereby facilitating the fixing of the copper tube inside the oil inlet valve connector, such as... Figure 2 As shown, this provides an oil inlet valve riveting clamp and an oil inlet valve connector assembly that can process copper pipes into a trumpet shape to facilitate users fixing copper pipes into the oil inlet valve connector.

[0007] To achieve the above objectives, this utility model provides an oil inlet valve riveting fixture, which includes: two jaws, a first screw, a shaping frame, and a second screw. The two jaws are arranged side by side and aligned, and the first screw is threaded through their respective sides. When the jaws are joined together, they are provided with mutually cooperating shaping holes on one side close to each other. The two shaping holes are flared when joined together. The second screw is vertically threaded onto the shaping frame, and its lower end is provided with a conical shaping head. The two ends of the shaping frame can be detachably set on the opposite sides of the joined jaws.

[0008] Preferably, after the two grippers are joined together, they are provided with a number of shaping holes of different radii at intervals on one side of each other, and the shaping holes of the same radius can be joined together to form a trumpet shape.

[0009] Preferably, the gripper has a plurality of first limiting posts protruding from the side away from the shaping hole, each corresponding to a shaping hole of a different radius, and a corresponding second limiting post is also provided on one side of each first limiting post. The shaping frame has first limiting grooves adapted to the first limiting posts at its two opposite ends, and second limiting grooves adapted to the second limiting posts are provided on its two opposite inner sides.

[0010] Preferably, a handshake is provided at one end of any of the grippers.

[0011] Preferably, a throttle is provided at the end of the first screw that extends out of the gripper.

[0012] Preferably, a rotating head is coaxially provided at the end of the second screw away from the conical shaping head, and the rotating head is surrounded by anti-slip texture.

[0013] Preferably, an oil inlet valve connector assembly is also provided, the oil inlet valve connector assembly comprising: a copper pipe, a first molded part, a first connector, and a second connector. One end of the copper pipe is flared, the first connector is sleeved on the copper pipe, and a first molded part adapted to the flared end of the copper pipe is movably disposed inside the first connector. One end of the second connector is provided with a second molded part adapted to the flared end of the copper pipe. One end of the first connector is provided with a threaded groove coaxially disposed on one end of the first molded part, and a threaded post coaxially disposed on the other end. The second connector can be threadedly assembled into the threaded groove of the first connector.

[0014] According to the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: The two jaws of this application pass through a threaded through hole on opposite sides and are threadedly connected by a first screw. By pressing down on one jaw and rotating the first screw, the distance between the two jaws can be adjusted, thereby clamping the copper tube through the shaping hole. Then, the shaping frame is installed on opposite sides of the two jaws, and the conical shaping head is aligned with the axis of the shaping hole, which becomes trumpet-shaped after merging. Then, the second screw is rotated to drive the conical shaping head closer to the copper tube, thereby cooperating with the shaping hole to shape one end of the copper tube into a trumpet shape. Then, the copper tube is cut to the required length to obtain a section. The copper pipe is flared to facilitate the user's fixation of the copper pipe section inside the oil inlet valve connector. When processing one end of the copper pipe into a flared shape, the first molding part and the first connector need to be fitted onto the copper pipe first. After processing one end of the copper pipe into a flared shape, the first molding part and the first connector are lifted upwards until the first molding part abuts against the flared end of the copper pipe. At this time, the second connector is tightened into the threaded groove of the first connector. The second molding part and the first molding part will be squeezed against the flared end of the copper pipe, thereby riveting the copper pipe inside the first connector and the second connector, ensuring sealing and preventing oil and air leakage. Finally, the part of the copper pipe extending out of the first connector is cut off.

[0026] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0027] Reference Figures 3-5 A riveting fixture for an oil inlet valve includes two jaws 1, a first screw 2, a shaping frame 3, and a second screw 4. The two jaws 1 are arranged side by side and aligned, with the first screw 2 threaded through their respective sides. Each jaw 1, when joined together, has a shaping hole 101 that fits into each other on one side. The two shaping holes 101, when joined together, form a trumpet shape. The second screw 4 is vertically threaded onto the shaping frame 3, and its lower end is provided with a tapered shaping head 401. The two ends of the shaping frame 3 are detachably mounted on the opposite sides of the joined jaws 1.

[0028] The two jaws 1 of this application pass through a threaded through hole on opposite sides and are threadedly connected by a first screw 2. By pressing one jaw 1 and rotating the first screw 2, the distance between the two jaws 1 can be adjusted, thereby clamping the copper tube 501 through the shaping hole 101. Then, the shaping frame 3 is installed on opposite sides of the two jaws 1, and the conical shaping head 401 is aligned with the axis of the shaping hole 101, which is flared after being merged. Then, the second screw 4 is rotated to drive the conical shaping head 401 closer to the copper tube 501, thereby cooperating with the shaping hole 101 to shape one end of the copper tube 501 into a flared shape. Then, the copper tube 501 is cut according to the required length to obtain a section of copper tube 501 with a flared end, so that the user can fix the section of copper tube 501 in the oil inlet valve connector.

[0029] Reference Figure 3 and Figure 4 After the two grippers 1 are combined, they are close to each other on one side and have several shaping holes 101 of different radii. Shaping holes 101 of the same radius can be combined to form a trumpet shape.

[0030] This application improves its applicability by setting multiple shaping holes 101 with different radii, thereby making it suitable for copper tubes 501 with various radii.

[0031] Reference Figure 4 and Figure 5 The gripper 1 has a plurality of first limiting posts 102 protruding from the side away from the shaping hole 101, each corresponding to a different radius of the shaping hole 101. A corresponding second limiting post 103 is also provided on one side of each first limiting post 102. The shaping frame 3 has first limiting grooves 301 at its two opposite ends that are adapted to the first limiting posts 102, and second limiting grooves 302 adapted to the second limiting posts 103 are provided on its two opposite inner sides.

[0032] The gripper 1 of this application has several columnar structures on the side away from the forming hole 101, with the number corresponding to the different radii of the forming holes 101. Assuming there are four different radii of forming holes 101, four first limiting posts 102 are correspondingly provided on the gripper 1. The first limiting posts 102 restrict the lateral movement of the forming frame 3, ensuring that the forming frame 3 remains in the correct position throughout the entire working process. The second limiting posts 103 restrict the rotation of the forming frame 3 around the first limiting posts 102, ensuring that the conical forming head 401 remains coaxial with the forming hole 101 throughout the entire working process, ensuring that one end of the copper tube 501 can be processed into a trumpet shape.

[0033] Reference Figure 4 A handshake 104 is provided at one end of any gripper 1.

[0034] This application provides a handshake 104 on only one gripper 1, so that the user can adjust the distance between the two grippers 1 by pressing one gripper 1 and rotating the first screw 2, thereby improving work efficiency.

[0035] Reference Figure 4 The first screw 2 has a throttle 201 at one end of the claw 1.

[0036] This application provides a throttle 201 so that the user can rotate the first screw 2, thereby adjusting the distance between the two grippers 1.

[0037] Reference Figure 5 The second screw 4 has a rotating head 402 coaxially arranged at the end away from the conical shaping head 401, and the rotating head 402 is surrounded by anti-slip texture.

[0038] This application provides a rotating head 402 with anti-slip texture so that the user can rotate the second screw 4 to adjust the position of the conical shaping head 401, which then cooperates with the shaping hole 101 to shape one end of the copper tube 501 into a trumpet shape.

[0039] Reference Figure 1 and Figure 5 An oil inlet valve connector assembly includes a copper pipe 501, a first molded part 502, a first connector 503, and a second connector 504. One end of the copper pipe 501 is flared. The first connector 503 is sleeved on the copper pipe 501, and the first molded part 502 adapted to the flared end of the copper pipe 501 is movably disposed inside the first molded part 502. One end of the second connector 504 is provided with a second molded part 505 adapted to the flared end of the copper pipe 501. The first connector 503 is provided with a threaded groove coaxially disposed at one end of the first molded part 502 and a threaded post coaxially disposed at the other end. The second connector 504 can be threadedly assembled into the threaded groove of the first connector 503.

[0040] When processing one end of the copper tube 501 into a trumpet shape, the first molding part 502 and the first connector 503 need to be fitted onto the copper tube 501 first. After processing one end of the copper tube 501 into a trumpet shape, the first molding part 502 and the first connector 503 are lifted upwards until the first molding part 502 abuts against the trumpet-shaped end of the copper tube 501. At this time, the second connector 504 is tightened into the threaded groove of the first connector 503. The second molding part 505 and the first molding part 502 will be squeezed against the trumpet-shaped end of the copper tube 501, thereby riveting the copper tube 501 into the inside of the first connector 503 and the second connector 504, ensuring sealing and preventing oil and air leakage. Finally, the part of the copper tube 501 extending out of the first connector 503 is cut off.

[0041] In use, the device provided by this utility model has two clamps 1 passing through a threaded through hole on opposite sides and connected by a first screw 2. By pressing one clamp 1 and rotating the first screw 2, the distance between the two clamps 1 can be adjusted, thereby clamping the copper tube 501 through the shaping hole 101. Then, the shaping frame 3 is installed on opposite sides of the two clamps 1, and the conical shaping head 401 is aligned with the axis of the combined funnel-shaped shaping hole 101. Then, the second screw 4 is rotated to drive the conical shaping head 401 closer to the copper tube 501, thereby cooperating with the shaping hole 101 to shape one end of the copper tube 501 into a funnel shape. Then, the copper tube 501 is cut according to the required length to obtain a section of copper tube 501 with a funnel-shaped end, so that the user can fix the section of copper tube 501 in the oil inlet valve connector. When processing one end of the copper tube 501 into a trumpet shape, the first molding part 502 and the first connector 503 need to be fitted onto the copper tube 501 first. After processing one end of the copper tube 501 into a trumpet shape, the first molding part 502 and the first connector 503 are lifted upwards until the first molding part 502 abuts against the trumpet-shaped end of the copper tube 501. At this time, the second connector 504 is tightened into the threaded groove of the first connector 503. The second molding part 505 and the first molding part 502 will be squeezed against the trumpet-shaped end of the copper tube 501, thereby riveting the copper tube 501 into the inside of the first connector 503 and the second connector 504, ensuring sealing and preventing oil and air leakage. Finally, the part of the copper tube 501 that extends out of the first connector 503 is cut off.
