Description

Technical Field

[0001] This utility model relates to the field of press-fitting technology for radiator water chambers, specifically, to a press-fitting error-proofing tooling for radiator water chambers. Background Technology

[0002] The radiator is an important component of a water-cooled engine. As an important part of the cooling circuit of a water-cooled engine, it can absorb the heat of the cylinder block and prevent the engine from overheating. During the press-fitting process, the sealing gaskets are usually placed on both sides of the radiator core, and then the radiator water chambers are installed on both sides of the radiator core. Finally, it is placed in the press-fitting machine for press-fitting.

[0003] In existing technologies, the water chamber of the radiator is usually installed manually onto the core. Typically, the radiator core is placed vertically, the water chamber is installed at one end of the core, and then it is placed in a press machine to press the water chamber onto one end of the core. Then, the water chamber is installed at the other end of the core and pressed again. This operation results in a large workload for workers and inevitably carries the possibility of errors in the installation of the water chamber. For example, if the worker does not accurately align the water chamber with the two ends of the radiator core, the water chamber will be installed incorrectly, resulting in product defects after pressing. Utility Model Content

[0004] This utility model proposes a press-fit anti-error tooling for radiator water chambers, which solves the problem in the prior art where workers do not accurately align the water chamber with both ends of the radiator core, resulting in incorrect installation position of the water chamber.

[0005] The technical solution of this utility model is as follows: A press-fitting anti-misalignment tooling for a radiator water chamber includes an operating table and a core. The core includes a main body and a main plate. The main plate is provided at both the top and bottom of the main body. The core is I-shaped. It also includes a rotating clamping member, a guiding assembly, and a locking mechanism. The rotating clamping member is provided on the outer side wall of the operating table for clamping and fixing the core. The guiding assembly is provided at both ends of the core and the water chamber for guiding the water chamber to accurately align with the core. The locking mechanism is provided on the outer side wall of the water chamber for locking and fixing the core to the water chamber.

[0006] To vertically fix the core and align the water chambers at both ends of the core, the water chambers are installed in two separate steps, saving time and facilitating operation. The rotating clamping component includes a rotating shaft, a first motor, a fixing frame, and a baffle. One end of the rotating shaft is rotatably connected to the outer wall of the operating table. The first motor is embedded in the operating table and located on one side of the rotating shaft. The output end of the first motor is coaxially and fixedly connected to one end of the rotating shaft. The center of one end of the fixing frame is fixedly connected to the other end of the rotating shaft. A fixing groove that mates with the main body is provided in the fixing frame. The length of the fixing groove is the same as the length of the main body. One end of the baffle passes through one end of the fixing frame. A positioning groove that mates with one end of the baffle is provided on the fixing frame. A fixing space is formed between the baffle and the inner wall of the fixing groove.

[0007] To prevent misalignment between the water chamber and the core, the guide assembly includes two guide seats, a guide rod, and two guide rings. The two guide seats are fixedly connected to both ends of the main plate, one end of the guide rod is fixedly connected to the top end of the guide seat, and the two guide rings are fixedly connected to both ends of the water chamber. The guide rings and the guide rod are in sliding engagement.

[0008] To secure the water chamber and the core together after docking, the locking mechanism includes multiple fixed seats, a guide rod, a slider, a spring, a locking seat, and a locking connector. Multiple fixed seats are fixedly connected to the outer wall of the water chamber. Each fixed seat has a movable groove. The two ends of the guide rod are fixedly connected to the two inner walls of the movable groove, respectively. The slider is disposed within the movable groove, with the guide rod passing through it. The slider slides against the inner wall of the movable groove. The spring is sleeved on the outer side of the guide rod, with one end fixedly connected to the inner wall of the movable groove away from the water chamber and the other end fixedly connected to the slider. The top end of the locking seat is fixedly connected to the bottom end of the slider, and the outer wall of the locking seat fits against the outer wall of the main piece. The top end of the locking connector is fixedly connected to the bottom end of the locking seat.

[0009] To prevent the core from moving left and right in the fixing groove and resulting in poor fixing effect, the width of the fixing space is the same as the width of the main body.

[0010] To increase the friction between the baffle and the fixed frame and prevent the baffle from falling off during the rotation of the fixed frame, the baffle is covered with an anti-slip sleeve.

[0011] In order to move the snap-fit ​​connector to the underside of the main piece and snap it in place, both the bottom end of the snap-fit ​​connector and the top end of the main piece are arc-shaped.

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

[0013] 1. In this utility model, by providing a rotating clamping component, the main body of the core is horizontally inserted into the fixing groove. The upper and lower ends of the fixing frame are attached to one end of the two main pieces, thus keeping the core vertically stable. When one end of the main body is attached to the inner wall of the fixing groove, the baffle and one end of the anti-slip sleeve pass through the outer wall of the fixing frame and are inserted into the positioning groove. One end of the anti-slip sleeve is attached to the other end of the main body, thus fixing the core horizontally. This can maintain the stability of the core. Furthermore, the first motor drives the core to "flip" 180 degrees, which facilitates the docking and installation of the water chamber at the other end of the core. This helps to save time and reduce the number of operation steps for workers.

[0014] 2. In this utility model, through the cooperation of the guide assembly and the locking mechanism, the handheld water chamber drives the two guide rings to insert into the guide rod and move downwards, thus maintaining the accurate docking of the water chamber and the core. During the docking process, one end of the arc shape of multiple snap-fit ​​connectors contacts one end of the arc shape of the main piece, and in subsequent movement, the top of the snap-fit ​​connector and one end of the snap-fit ​​seat press against the main piece. At this time, the bottom end of the water chamber fits against the top end of the main piece, and the "four corners" of the main piece are locked, thus completing the docking installation of the water chamber at one end of the core. This allows the water chamber and the core to be accurately docked and installed, avoiding errors. Attached Figure Description

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] like Figures 1-6 As shown, this embodiment proposes a press-fitting error-proof tooling for radiator water chambers, including an operating table 1 and a core 2. The core 2 includes a main body 3 and a main plate 4. The main plate 4 is provided at both the top and bottom of the main body 3. The core 2 is "I" shaped and also includes a rotating clamping component, a guide assembly, and a locking mechanism.

[0025] like Figure 2 , Figure 5 and Figure 6As shown, a rotating clamping component is installed on the outer wall of the operating table 1 to clamp and fix the core 2. To vertically fix the core 2 and align the water chambers 5 at both ends of the core 2, the water chambers 5 are installed in two stages, which saves time and facilitates operation. The rotating clamping component includes a rotating shaft 6, a first motor 7, a fixing frame 8, and a baffle 9. One end of the rotating shaft 6 is rotatably connected to the outer wall of the operating table 1. The first motor 7 is embedded in the operating table 1 and is located on one side of the rotating shaft 6. The output end of the first motor 7 is connected to the rotating shaft 6. One end of shaft 6 is coaxially fixedly connected. The first motor 7 is a power-off braking motor. When energized, the rotor moves backward due to magnetic force. When the brake is released, the motor can rotate. When de-energized, the rotor moves forward due to the action of spring 19. When the brake is engaged, the motor cannot rotate. The center of one end of the fixed frame 8 is fixedly connected to the other end of the rotating shaft 6. A fixing groove 10 is provided in the fixed frame 8 to cooperate with the main body 3. The length of the fixing groove 10 is the same as the length of the main body 3. One end of the baffle 9 passes through one end of the fixed frame 8 to increase the friction between the baffle 9 and the fixed frame 8. To prevent the baffle 9 from falling off during the rotation of the fixed frame 8, an anti-slip sleeve 22 is provided on the outer sleeve of the baffle 9. A positioning groove 11 is provided on the fixed frame 8 to mate with one end of the baffle 9. A fixing space 12 is formed between the baffle 9 and the inner wall of the fixing groove 10. To prevent the core 2 from moving left and right in the fixing groove 10 and resulting in poor fixing effect, the width of the fixing space 12 is the same as the width of the main body 3. By inserting the main body 3 of the core 2 horizontally into the fixing groove 10, the upper and lower ends of the fixed frame 8 are attached to one end of the two main pieces 4, thus keeping the core 2 in place. When the main body 3 is fixed and stationary, and one end of the main body 3 is attached to the inner wall of the fixing groove 10, the baffle 9 and one end of the anti-slip sleeve 22 are inserted into the positioning groove 11 through the outer wall of the fixing frame 8. One end of the anti-slip sleeve 22 is attached to the other end of the main body 3, thus fixing the core 2 horizontally. By starting the first motor 7, the output end of the first motor 7 rotates and drives the rotating shaft 6 to rotate, which in turn drives the fixing frame 8 to rotate. By rotating 180 degrees, the core 2 is "flipped" to facilitate the docking and installation of the water chamber 5 at the other end of the core 2.

[0026] like Figure 3 and Figure 4 As shown, the guide assembly is set at both ends of the core 2 and the water chamber 5 to guide the water chamber 5 to accurately align with the core 2. To avoid errors in the alignment of the water chamber 5 and the core 2, the guide assembly includes two guide seats 13, a guide rod 14, and two guide rings 15. The two guide seats 13 are fixedly connected to both ends of the main plate 4, one end of the guide rod 14 is fixedly connected to the top end of the guide seat 13, and the two guide rings 15 are fixedly connected to both ends of the water chamber 5. The guide rings 15 and the guide rod 14 are slidably engaged. By holding the water chamber 5, the two guide rings 15 are inserted into the guide rod 14 and moved downwards, thus maintaining the accurate alignment of the water chamber 5 and the core 2.

[0027] like Figure 3 and Figure 4 As shown, the locking mechanism is installed on the outer wall of the water chamber 5 to secure the core 2 to the water chamber 5. To fix the water chamber 5 and core 2 together after docking, the locking mechanism includes multiple fixing seats 16, a smooth rod 17, a slider 18, a spring 19, a locking seat 20, and a locking connector 21. Multiple fixing seats 16 are fixedly connected to the outer wall of the water chamber 5, symmetrically arranged on the outer wall. Each fixing seat 16 has a movable groove, and both ends of the smooth rod 17 are respectively connected to the movable groove. The two inner sidewalls are fixedly connected. The slider 18 is set in the moving groove. The smooth rod 17 passes through the slider 18. The slider 18 slides with the inner sidewall of the moving groove. The spring 19 is sleeved on the outside of the smooth rod 17. One end of the spring 19 is fixedly connected to the inner sidewall of the moving groove away from the water chamber 5, and the other end is fixedly connected to the slider 18. The top end of the snap-fit ​​seat 20 is fixedly connected to the bottom end of the slider 18. The outer sidewall of the snap-fit ​​seat 20 fits against the outer sidewall of the main plate 4. The top end of the snap-fit ​​connector 21 is fixedly connected to the bottom end of the snap-fit ​​seat 20. To move the snap-fit ​​connector 21 to the underside of the main plate 4 and secure it in place, both the bottom end of the snap-fit ​​connector 21 and the top end of the main plate 4 are arc-shaped. The distance between the bottom end of the snap-fit ​​connector 21 and the water chamber 5 is equal to the thickness of the main plate 4. As the water chamber 5 moves vertically downward under the guidance of the guide assembly, one arc-shaped end of multiple snap-fit ​​connectors 21 contacts one arc-shaped end of the main plate 4. The main plate 4 presses the snap-fit ​​connector 21 away from the main plate 4, causing the snap-fit ​​connector 21 to move, which in turn moves the snap-fit ​​seat 20. The snap-fit ​​seat 20 then moves the slider 18 along the guide rod. As the slider 18 moves under the guidance of 17, it compresses the spring 19, causing the spring 19 to contract. During the subsequent downward movement, after the top of the snap-fit ​​connector 21 is below the bottom of the main piece 4, the spring 19 pushes the slider 18 closer to the main piece 4, causing the snap-fit ​​seat 20 and snap-fit ​​connector 21 to move. The top of the snap-fit ​​connector 21 and one end of the snap-fit ​​seat 20 press against the main piece 4. At this time, the bottom of the water chamber 5 is in contact with the top of the main piece 4, and the "four corners" of the main piece 4 are locked. This completes the docking and installation of the water chamber 5 at one end of the core 2.

[0028] Working principle: When installing the water chambers 5 at both ends of the core 2, the main body 3 of the core 2 is inserted laterally into the fixing groove 10. The upper and lower ends of the fixing frame 8 are attached to one end of the two main pieces 4, thus keeping the core 2 vertically stable. When one end of the main body 3 is attached to the inner wall of the fixing groove 10, the baffle 9, along with one end of the anti-slip sleeve 22, is inserted into the positioning groove 11 through the outer wall of the fixing frame 8. One end of the anti-slip sleeve 22 is attached to the other end of the main body 3, thus fixing the core 2 laterally. At this time, the core 2 remains vertical. By holding the water chamber 5, the two guide rings 15 are inserted into the guide rod 14 and moved downwards, thus maintaining the accurate docking of the water chamber 5 and the core 2. During the docking process, the arc-shaped ends of multiple snap-fit ​​connectors 21 contact the arc-shaped ends of the main pieces 4, and subsequently... During the movement, the main piece 4 presses the snap-fit ​​connector 21 away from the main piece 4. The snap-fit ​​connector 21 drives the snap-fit ​​base 20 to move. The snap-fit ​​base 20 drives the slider 18 to move under the guidance of the light rod 17. The slider 18 presses the spring 19, and the spring 19 contracts. When the top of the snap-fit ​​connector 21 is below the bottom of the main piece 4, the spring 19 pushes the slider 18 closer to the main piece 4, driving the snap-fit ​​base 20 and the snap-fit ​​connector 21 to move. The top of the snap-fit ​​connector 21 and one end of the snap-fit ​​base 20 press against the main piece 4. At this time, the bottom of the water chamber 5 is in contact with the top of the main piece 4, and the "four corners" of the main piece 4 are locked. This completes the docking installation of the water chamber 5 at one end of the core 2. Then, the first motor 7 drives the fixed frame 8 to rotate. By rotating 180 degrees, the core 2 is "flipped" to facilitate the docking installation of the water chamber 5 at the other end of the core 2.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
