Description

Technical Field

[0001] This utility model belongs to the field of tee connector manufacturing technology, and more specifically, it relates to a clamping device for tee connector manufacturing. Background Technology

[0002] In the field of pipeline system manufacturing, tee fittings are a key connection component. Generally speaking, plastic tee fittings are usually injection molded, so there is often excess material at the gate, which needs to be ground, or beveling, drilling and other processes depending on its use. Therefore, in order to ensure processing accuracy and efficiency, fixtures are used to provide reliable clamping during the production process.

[0003] Existing clamping methods typically use V-blocks in conjunction with pressure plates, with the clamping point located at the end of the main or branch pipe of the tee. However, since tees come in various specifications, clamping requires changing the clamp model or readjusting the position, resulting in poor versatility. Furthermore, once one pipe end is processed, it cannot be directly replaced for processing another pipe end; it needs to be re-clamped and fixed, leading to low overall applicability.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a clamping device for the production of tee connectors, in order to achieve a more practical purpose. Utility Model Content

[0005] In view of the problems mentioned in the background art above, this utility model provides a clamping device for the production of tee connectors.

[0006] The technical solution adopted by this utility model is as follows: A clamping device for producing tee connectors includes a mounting frame and a clamping seat. A placement seat is rotatably mounted on the mounting frame. The clamping seat is mounted on the mounting frame via a driving mechanism and is located directly above the placement seat. A plurality of clamping members are arranged in an array on the clamping seat, and each clamping member adaptively abuts against the surface of the tee connector via an elastic element. The driving mechanism includes a pressing cylinder and a connecting box. The pressing cylinder is mounted on the mounting frame and its drive shaft is connected to the connecting box. The clamping seat is rotatably connected to the connecting box, and the connecting box is used to mount a motor. The clamping seat is driven by the motor.

[0007] Furthermore, the clamping member includes a clamping post, and the clamping seat has a sliding cavity for inserting the clamping post. Limiting grooves are provided on both sides of the clamping post, and a limiting block matching the limiting groove is provided in the sliding cavity. The elastic element is provided in the sliding cavity for contacting the end of the clamping post.

[0008] Furthermore, the elastic element is a rubber pad filled in the sliding cavity, and the rubber pad does not abut against the end of the clamping post.

[0009] Furthermore, a suction cup is provided at the head end of the clamping column.

[0010] Furthermore, the placement base is provided with an array of several rubber protrusions.

[0011] Furthermore, a limit baffle is provided on the placement seat.

[0012] The beneficial effects of this utility model are:

[0013] 1. The clamping seat is mounted on the mounting frame and located directly above the placement seat via a drive mechanism. The clamping seat and the connecting box are rotatably connected, and the connecting box contains a drive motor. When the drive motor starts, its output shaft can drive the clamping seat to rotate around its own axis, while the downward cylinder drives the entire clamping seat to rise and fall vertically through the connecting box. Since the placement seat can rotate on the mounting frame, after processing one pipe end, there is no need to disassemble the tee connector. The other pipe end to be processed can be adjusted to be directly below the clamping seat by rotating the placement seat with external power or manually, achieving multi-face continuous processing. Secondly, since the clamping seat is equipped with several clamping components, and each clamping component can adaptively abut against the surface of the tee head through an elastic element, each clamping component can adaptively adjust its extension length according to the actual contour of the tee head surface, thereby achieving multi-point uniform contact on irregular or asymmetrical surfaces, realizing adaptive clamping, significantly improving the versatility and clamping reliability of the fixture, and solving the problem of unstable clamping or poor adaptability caused by fixed clamping points in the prior art.

[0014] 2. When the clamping column begins to move downward under the action of gravity or external pressure, its end first slides freely down a certain distance in the sliding cavity until it contacts the rubber pad before compressing the rubber pad. This non-pre-compression design gives the clamping column a "buffer stroke" when it initially contacts the workpiece. That is, at the moment the clamping column contacts the workpiece, the system does not immediately generate elastic reaction force, but allows the clamping column to quickly conform to the workpiece surface without resistance. As the downward pressure continues to increase, the rubber pad is compressed, gradually building up the clamping force. This avoids sudden changes in clamping force caused by the pre-tightening of the elastic element and reduces the risk of impact on the workpiece surface. Secondly, the rubber pad provides a progressive reaction force during compression, so that the clamping force is built up evenly, preventing local stress concentration. The overall structure enhances the stability of the clamping process, protects the surface of the plastic tee connector from scratches or deformation, and absorbs small assembly errors through material deformation, further improving the adaptability and stability of the clamping.

[0021] like Figures 1-3 As shown, a clamping device for producing tee connectors includes a mounting frame 1 and a clamping seat 3. A placement seat 2 is rotatably mounted on the mounting frame 1. The clamping seat 3 is mounted on the mounting frame 1 via a driving mechanism and is located directly above the placement seat 2. A plurality of clamping elements are arranged in an array on the clamping seat 3, and each clamping element adaptively abuts against the surface of the tee connector via an elastic element. The driving mechanism includes a pressing cylinder 11 and a connecting box 12. The pressing cylinder 11 is mounted on the mounting frame 1, and the drive shaft of the pressing cylinder 11 is connected to the connecting box 12. The clamping seat 3 is rotatably connected to the connecting box 12, and the connecting box 12 is used to mount a motor. The clamping seat 3 is driven by the motor.

[0022] Using the above technical solution, the clamping seat 3 is set on the mounting frame 1 and located directly above the placement seat 2 through the drive mechanism, and the clamping seat 3 and the connecting box 12 are rotatably connected, and the connecting box 12 is equipped with a drive motor. When the drive motor starts, its output shaft can drive the clamping seat 3 to rotate around its own axis, while the pressing cylinder 11 drives the entire clamping seat 3 to rise and fall vertically through the connecting box 12. Since the placement seat 2 can rotate on the mounting frame 1, after processing one pipe head, there is no need to disassemble the tee connector. The other pipe head to be processed can be adjusted to the underside of the clamping seat 3 by rotating the placement seat 2 with external power or manually, so as to achieve multi-face continuous processing. Secondly, since the clamping seat 3 is equipped with several clamping parts, and each clamping part can adaptively abut against the surface of the tee head through the elastic element, each clamping part can adaptively adjust its extension length according to the actual contour of the tee head surface, thereby achieving multi-point uniform contact on irregular or asymmetrical surfaces, realizing adaptive clamping, significantly improving the versatility and clamping reliability of the fixture, and solving the problem of unstable clamping or poor adaptability caused by fixed clamping points in the prior art.

[0023] As a preferred embodiment, the clamping member includes a clamping post 4. The clamping seat 3 has a sliding cavity 31 for inserting the clamping post 4. Limiting grooves 41 are formed on both sides of the clamping post 4. A limiting block 32 matching the limiting groove 41 is provided in the sliding cavity 31. The elastic element is disposed in the sliding cavity 31 for contacting the end of the clamping post 4. When the clamping seat 3 is pressed down, the first end of the clamping post 4 contacts the surface of the tee connector. With the continuous action of the downward pressure, the clamping post 4 slides inward in the sliding cavity 31 against the reaction force of the elastic element. Its displacement depends on the local height difference of the tee connector surface. Since multiple clamping posts 4 slide independently, the extension length of each clamping point can be adaptively adjusted according to the actual contour of the tee connector surface, thereby achieving multi-point uniform contact clamping of irregular or asymmetrical surfaces, significantly improving the versatility and clamping reliability of the fixture, and solving the problem of clamping instability or adaptability caused by fixed clamping points in the prior art.

[0024] As a preferred embodiment, the elastic element is a rubber pad 33 filled in the sliding cavity 31, and the rubber pad 33 does not abut against the end of the clamping post 4. When the clamping column 4 begins to move downward under the action of gravity or external pressure, its end first moves freely down a certain distance in the sliding cavity 31 until it contacts the rubber pad 33 before compressing the rubber pad 33. This non-pre-compression design gives the clamping column 4 a "buffer stroke" when it initially contacts the workpiece. That is, at the moment the clamping column 4 contacts the workpiece, the system does not immediately generate elastic reaction force, but allows the clamping column 4 to quickly adhere to the workpiece surface without resistance. As the downward pressure continues to increase, the rubber pad 33 is compressed, gradually building up the clamping force. This avoids sudden changes in clamping force caused by the pre-tightening of the elastic element and reduces the risk of impact on the workpiece surface. Secondly, the rubber pad 33 provides a progressive reaction force during the compression process, so that the clamping force is built up evenly, preventing local stress concentration. The overall structure enhances the stability of the clamping process, protects the surface of the plastic tee connector from scratches or deformation, and absorbs small assembly errors through material deformation, further improving the adaptability and stability of the clamping.

[0025] As a preferred embodiment, the clamping post 4 is provided with a suction cup 42 at its head end. When the clamping post 4 contacts the surface of the tee connector and continues to press down, the edge of the suction cup 42 forms a sealed cavity with the workpiece surface, the internal air is squeezed out, and the external atmospheric pressure presses the suction cup 42 tightly against the workpiece surface, thereby generating an adsorption force. Since the suction cup 42 has a certain degree of flexibility and conformability, even if there are slight unevenness or curvature changes on the workpiece surface, the suction cup 42 can achieve local sealing through deformation and maintain the adsorption effect. Compared with the point contact of the clamping post 4, the suction cup 42 is transformed into a surface contact with the tee connector, which effectively improves the clamping performance while preventing damage to the surface of the tee connector.

[0026] As a preferred embodiment, the placement base 2 is provided with an array of rubber protrusions 21. The surface of the placement base 2 is provided with an array of rubber protrusions 21. When the bottom of the tee connector is placed on the placement base 2, the rubber protrusions 21 form point contact or small-area contact with the bottom surface of the workpiece. Rubber material has a high coefficient of friction and a certain degree of compression resilience. When the clamping seat 3 presses down, the rubber protrusions 21 deform under pressure, increasing the contact area with the workpiece and generating a reaction force. This reaction force and the downward pressure of the clamping seat 3 form a pair of balanced forces, ensuring stable support for the workpiece. Furthermore, the gaps between the rubber protrusions 21 can accommodate any remaining gate material or burrs that may exist at the bottom of the workpiece, preventing the workpiece from tilting or experiencing uneven stress due to localized protrusions.

[0027] As a preferred embodiment, a limiting baffle 22 is provided on the placement seat 2. The limiting baffle 22 is positioned corresponding to the outer end face of one of the pipe ends of the tee connector. When the tee pipe is placed on the placement seat 2, its pipe end face contacts the limiting baffle 22, forming an axial positioning reference. After the clamping seat 3 presses down and completes the clamping, the tee pipe cannot move along the normal direction of the baffle under the constraint of the limiting baffle 22, thus maintaining its position unchanged during subsequent drilling or beveling.
