Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing, and in particular to a connecting tooling for automotive condensers. Background Technology

[0002] In the field of automotive air conditioning system component manufacturing, the automotive condenser is a core heat exchange component. Its assembly process requires the precise docking and fixing of key components such as the condenser body, bracket, and connecting pipes. The automotive condenser connection tooling is a special mechanical equipment designed specifically for this assembly process. It is widely used in the mass production line of automotive condensers and is a key piece of equipment connecting the feeding of condenser components with subsequent precision machining processes such as welding and sealing.

[0003] Existing automotive condenser connection tooling has several problems: First, most existing automotive condenser connection tooling uses a single-station, unseparated or multi-station, dispersed, unintegrated transfer structure. For example, the former does not delineate a dedicated placement space within a single workbench area, relying solely on simple blocks to distinguish the placement positions of the automotive condenser and the bracket. During operation, the condenser must be placed manually first, and then the bracket must be manually moved to the side of the condenser, repeatedly adjusting their positions to align with the connection reference. During this process, the lack of physical separation can easily lead to component collisions and interference, and the manual handling and adjustment steps are cumbersome, easily causing misalignment of the docking reference due to operational errors. The latter, although separating condenser placement and bracket storage into two independent workstations, lacks an integrated automated transfer mechanism between the two workstations. It relies on manual or independent conveyor belts to transfer the bracket. During the transfer process, the bracket is easily deviated from the preset position due to vibration and uneven manual handling force. Furthermore, the positioning and clamping actions of each workstation lack unified electronic control coordination, requiring manual operation of each mechanism separately, resulting in a fragmented workflow, low automation, and difficulty in ensuring the consistency of condenser connections in mass production. Secondly, the positioning mechanism of the condenser often adopts manual bolt locking or pneumatic asynchronous locking structure. Firstly, the manual bolt locking structure requires an ear plate with a slotted hole next to the positioning slider. After the slider is adjusted, a wrench is used to manually tighten the bolt through the slotted hole to fix the slider. This is not only inefficient, but the inconsistent tightening force can easily lead to uneven bolt tightness, causing the slider to easily shift during subsequent vibrations. Secondly, the pneumatic asynchronous locking structure uses a separate pneumatic clamping cylinder. The clamping cylinder is not linked to the positioning slider. After the slider is adjusted, the clamping cylinder needs to be manually moved to align with the side of the slider before clamping. This can easily cause the clamping force application point to deviate due to cylinder position misalignment, resulting in local deformation of the slider or locking failure. Both types of locking structures rely on manual intervention, increasing human error and failing to achieve synchronous coordination between positioning and locking, making it difficult to guarantee the stability of positioning accuracy. Utility Model Content

[0004] This utility model provides an automotive condenser connection fixture that can solve the problem of low station separation efficiency in existing automotive condenser connection fixtures.

[0005] A car condenser connection fixture includes a workbench, a three-axis platform on the workbench, and a controller on the workbench. The area enclosed in the middle of the three-axis platform is divided into two independent areas, namely a first area for placing the car condenser and a hollow second area that runs through the workbench. The second area is the area for placing the condenser bracket. The Y-axis moving platform of the three-axis platform is provided with a first gripper that can grip the condenser bracket. The first area is provided with a positioning mechanism that can position the automotive condenser. The workbench is provided with a gantry frame facing the first area and close to the edge of the workbench. The gantry frame is provided with a clamping mechanism that can grip the pipe. The controller is electrically connected to the positioning mechanism and the clamping mechanism respectively.

[0006] Preferably, the positioning mechanisms are arranged in a cross-shaped symmetrical arrangement within the first area, and each positioning mechanism includes a first slide groove, a first slider, a push plate, and an elastic block. The first slider is slidably disposed in the first groove; The push plate is fixedly installed on the side of the first slider that is close to the car condenser; The elastic block is fixedly installed on the side of the push plate near the car condenser by bolts.

[0007] Preferably, the first slide groove has a hole along its own length, the first slider has a through threaded hole, and a nut is fixedly installed on the side of the first slider near the locking mechanism.

[0008] Preferably, a locking mechanism is provided next to each positioning mechanism, and the locking mechanism includes a second slide groove, a second slider, a stepper motor, and a bolt; The second slider is slidably disposed in the second groove; The stepper motor is fixedly mounted on the second slider; One end of the bolt is fixedly connected to the output end of the stepper motor, and the other end of the bolt is threadedly connected to a nut.

[0009] Preferably, the locking mechanism moves synchronously along its respective slide along the positioning mechanism, and the controller is electrically connected to the locking mechanism.

[0010] Preferably, the gantry frame is provided with a third sliding groove, and a third sliding block that can move along the third sliding groove is provided in the third sliding groove. The pipe clamping mechanism is symmetrically fixed on the third sliding block.

[0011] Preferably, the pipe clamping mechanism includes a cylinder and a second gripper; The cylinder is placed vertically and its bottom is fixedly mounted on the third slider, with the output end of the cylinder aligned with the first area; The bottom of the second gripper is fixedly mounted on the output end of the cylinder.

[0012] Preferably, the first gripper is provided with a first pressure sensor.

[0013] Preferably, the second gripper is provided with a second pressure sensor.

[0014] Preferably, both the first pressure sensor and the second pressure sensor are electrically connected to the controller.

[0015] The beneficial effects of this utility model are as follows: Through the coordinated action of the worktable, the dual areas of the three-axis platform, the first gripper of the Y-axis moving platform, the positioning mechanism of the first area, the clamping mechanism of the gantry, and the controller, the central area of ​​the three-axis platform is divided into a first area specifically for placing the automotive condenser and a condenser bracket placement area through the hollow worktable. The Y-axis moving platform drives the first gripper to accurately pick up and place the bracket from the second area. The positioning mechanism positions the condenser in the first area. The controller coordinates the actions of the positioning mechanism and the clamping mechanism in real time, realizing the physical separation of the automotive condenser and the bracket placement position to avoid mutual interference during the picking and placing process. It eliminates the step of manually transferring the bracket to simplify the operation process, while ensuring the automated operation of the overall tooling and the consistency of the condenser connection.

[0016] By cooperating with the second slide groove, second slider, stepper motor, and bolt of the locking mechanism and the first slider of the positioning mechanism, the locking mechanism is positioned next to the positioning mechanism. This allows the second slider to move synchronously with the first slider along the second slide groove. The stepper motor drives the bolt to connect with the nut of the first slider. This enables the positioning mechanism to be quickly locked after being adjusted to the correct position to prevent displacement due to vibration or external force during operation, ensuring stable positioning accuracy. At the same time, manual locking is not required, reducing human error and further improving the efficiency of tooling positioning and subsequent connection operations. Attached Figure Description

Detailed Implementation

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0020] like Figures 1 to 2 As shown in the figure, an embodiment of the present invention provides an automotive condenser connection fixture, including a workbench 1, a three-axis platform 2 on the workbench 1, and a controller 3 on the workbench 1. The area enclosed in the middle of the three-axis platform 2 is divided into two independent areas, namely a first area 21 for placing the automotive condenser and a hollow second area 22 that penetrates the workbench 1. The second area 22 is the area for placing the condenser bracket. The Y-axis moving platform 23 of the three-axis platform 2 is provided with a first gripper 4 for gripping the condenser bracket. The first area 21 is provided with a positioning mechanism 5 for positioning the automotive condenser. The workbench 1 is provided with a gantry 6 facing the first area 21 and close to the edge of the workbench 1. The gantry 6 is provided with a clamping mechanism 7 for clamping pipes. The controller 3 is electrically connected to the positioning mechanism 5 and the clamping mechanism 7 respectively.

[0021] The workbench 1 provides the installation foundation for the entire tooling. The three-axis platform 2, controller 3, positioning mechanism 5, gantry 6, etc., are all directly or indirectly fixed to the workbench 1, forming a stable overall structure. The middle area of ​​the three-axis platform 2 is divided into a first area 21 and a second area 22, which physically separates the placement of the automotive condenser and the condenser bracket, avoiding interference when they are placed or removed. The second area 22 is designed to be hollow and runs through the workbench 1, facilitating the storage and removal of the condenser bracket while saving surface space on the workbench 1. The connection between the Y-axis moving platform 23 and the first gripper 4 allows the first gripper 4 to move with the machine. The Y-axis moving platform 23 moves along the Y-axis direction to accurately pick up and place the condenser bracket from the second area 22 without manual transfer, reducing operation steps. The positioning mechanism 5 is set in the first area 21 to position the car condenser placed there, ensuring its stable position and providing a reference for subsequent connection operations. The gantry 6 faces the first area 21, and the clamping mechanism 7 on it can accurately clamp the pipes and perform connection operations in accordance with the position of the car condenser. The controller 3 is electrically connected to the positioning mechanism 5 and the clamping mechanism 7, so that the two can work together under the coordination of the controller 3, improving the automation and consistency of the operation.

[0022] like Figures 3 to 5 As shown, the positioning mechanisms 5 are arranged in a cross-shaped symmetrical arrangement within the first region 21, and each positioning mechanism 5 includes a first slide groove 51, a first slider 52, a push plate 53, and an elastic block 54. The first slider 52 is slidably disposed in the first groove 51; The push plate 53 is fixedly installed on the side of the first slider 52 near the car condenser; The elastic block 54 is fixedly installed on the side of the push plate 53 near the car condenser by bolts.

[0023] The positioning mechanism 5 is placed symmetrically in the first area 21 in a cross shape, and can position the car condenser from four vertical directions to ensure that the center position of the condenser is aligned with the preset reference, avoiding offset caused by unidirectional positioning. The first slider 52 is slidably disposed in the first slide groove 51, so that the positioning mechanism 5 can be adjusted along the length of the first slide groove 51 to adapt to car condensers of different sizes and improve the versatility of the tooling. The push plate 53 is fixed on the first slider 52 and serves as a force transmission component, converting the movement of the first slider 52 into a pushing force on the car condenser, ensuring uniform positioning force. The elastic block 54 is fixed to the push plate 53 by bolts. When the push plate 53 pushes the condenser, the elastic block 54 directly contacts the condenser, using its elastic properties to buffer the pushing force and avoid rigid contact that could cause scratches or deformation on the condenser surface. At the same time, the bolt connection method facilitates the replacement of the elastic block 54, and the elastic block 54 can be quickly replaced when it is worn, reducing maintenance costs.

[0024] The first slide groove 51 has a hole along its own length direction, the first slider 52 has a through threaded hole, and a nut 521 is fixedly installed on the side of the first slider 52 near the locking mechanism 8.

[0025] The holes provided along the length of the first slide groove 51 can serve as auxiliary positioning points for adjusting the position of the first slider 52, and can also be used to install limiting components to restrict the sliding range of the first slider 52 and prevent it from falling out of the first slide groove 51. The through threaded hole on the first slider 52 cooperates with the nut 521 to provide a threaded connection basis for the locking mechanism 8.

[0026] Each of the positioning mechanisms 5 is provided with a locking mechanism 8, which includes a second slide groove 81, a second slider 82, a stepper motor 83, and a bolt 84. The second slider 82 is slidably disposed in the second slide groove 81; The stepper motor 83 is fixedly mounted on the second slider 82; One end of the bolt 84 is fixedly connected to the output end of the stepper motor 83, and the other end of the bolt 84 is threadedly connected to the nut 521.

[0027] Each positioning mechanism 5 is equipped with a locking mechanism 8, which can lock the positioning mechanism 5 after it is adjusted to the correct position, ensuring that the positioning mechanism 5 is stable during operation. The second slider 82 is slidably disposed in the second slide groove 81, so that the locking mechanism 8 can adjust its position synchronously with the movement of the positioning mechanism 5, ensuring that the bolt 84 always corresponds to the nut 521, and ensuring that the locking function is effective. The stepper motor 83 is fixed on the second slider 82, providing power for the rotation of the bolt 84. Its output end is fixedly connected to the bolt 84, which can precisely control the screwing depth of the bolt 84. The threaded connection between the bolt 84 and the nut 521, through the friction generated by the thread engagement, fixes the first slider 52 in the preset position of the first slide groove 51, preventing the positioning mechanism 5 from being displaced due to vibration or external force during operation, and improving the positioning accuracy.

[0028] The locking mechanism 8 moves synchronously along its respective slide along the positioning mechanism 5, and the controller 3 is electrically connected to the locking mechanism 8.

[0029] The locking mechanism 8 moves synchronously along its respective slide along the positioning mechanism 5, ensuring that the locking mechanism 8 is always in an effective position that can be locked during the positioning mechanism 5's position adjustment process, thus avoiding locking failure due to misalignment between the two. The controller 3 is electrically connected to the locking mechanism 8, enabling the controller 3 to control the start, stop, and rotation direction of the stepper motor 83 according to the position signal of the positioning mechanism 5, thereby achieving the function of automatic locking after positioning and automatic unlocking when adjustment is required. No manual operation of the locking mechanism 8 is required, reducing human error and improving work efficiency and automation.

[0030] The gantry frame 6 is provided with a third sliding groove 61, and a third sliding block 62 that can move along the third sliding groove 61 is provided in the third sliding groove 61. The pipe clamping mechanism 7 is symmetrically fixed on the third sliding block 62.

[0031] The third slide groove 61 on the gantry 6 provides a moving track for the third slider 62. The third slider 62 can move along the third slide groove 61, driving the pipe clamping mechanism 7 to adjust its position to adapt to the pipe connection position of different models of automotive condensers, thereby improving the versatility of the tooling. The pipe clamping mechanism 7 is symmetrically fixed on the third slider 62, so that the pipe is subjected to uniform force on both sides when it is clamped, avoiding pipe bending or displacement due to uneven force, ensuring the docking accuracy between the pipe and the automotive condenser, and improving the connection quality.

[0032] The pipe clamping mechanism 7 includes a cylinder 71 and a second gripper 72; The cylinder 71 is placed vertically and its bottom is fixedly mounted on the third slider 62. The output end of the cylinder 71 is aligned with the first area 21. The bottom of the second gripper 72 is fixedly mounted on the output end of the cylinder 71.

[0033] The cylinder 71 is placed vertically and fixed on the third slider 62, providing vertical driving force for the second gripper 72. Its output end is aligned with the first area 21, ensuring that the second gripper 72 can accurately align with the car condenser in the first area 21 after clamping the pipe, facilitating the connection between the pipe and the car condenser. The second gripper 72 is fixed on the output end of the cylinder 71 and can move vertically under the drive of the cylinder 71 to realize the clamping and releasing action of the pipe. The structure is simple, the response is fast, and it can stably clamp pipes of different diameters, providing stable support for the connection between the pipe and the car condenser.

[0034] The first gripper 4 is equipped with a first pressure sensor 41.

[0035] The first pressure sensor 41 is installed on the first gripper 4, which can detect the pressure of the first gripper 4 when it clamps the condenser bracket in real time. By detecting the pressure value, it can be determined whether the first gripper 4 is firmly clamping the condenser bracket. If the pressure is too low, the condenser bracket may fall off during the transfer process. If the pressure is too high, the condenser bracket may be damaged. This design can avoid damage or fall off of the condenser bracket due to improper clamping force, and ensure the reliability of the condenser bracket transfer process.

[0036] The second gripper 72 is equipped with a second pressure sensor 721.

[0037] The second pressure sensor 721 is mounted on the second gripper 72 and can detect the pressure of the second gripper 72 when it clamps the pipe in real time. The pipe material is usually fragile. If the clamping pressure is too high, it may cause the pipe to deform or break. If the pressure is too low, the pipe may be displaced during the connection process. By detecting the pressure value, it can be ensured that the clamping force of the second gripper 72 on the pipe is within a suitable range, so as to avoid damage to the pipe and ensure the stability of the pipe position during the connection process, thereby improving the connection quality.

[0038] Both the first pressure sensor 41 and the second pressure sensor 721 are electrically connected to the controller 3.

[0039] The electrical connection between the first pressure sensor 41, the second pressure sensor 721, and the controller 3 enables the pressure signals detected by the sensors to be transmitted to the controller 3 in real time. The controller 3 can receive and process these pressure signals. When the pressure value exceeds the preset range, the controller 3 can issue a command to adjust the clamping force of the first gripper 4 or the second gripper 72, forming a closed-loop control. This design avoids the error of manually judging whether the clamping force is appropriate, making the clamping force control more precise and further improving the stability and reliability of clamping and connection operations.

[0040] In summary, the working principle of the automotive condenser connection fixture provided by this utility model embodiment is as follows: Using the workbench 1 as the installation base, the automotive condenser is first placed in the first area 21 surrounded by the three-axis platform 2. The condenser bracket is placed in the hollow second area 22 that penetrates the workbench 1. The controller 3 first controls the cross-shaped symmetrical positioning mechanism 5 within the first area 21 to move. The first slider 52 slides along the first groove 51, driving the push plate 53 and elastic block 54 to position the automotive condenser from four directions. After positioning, the locking mechanism 8 next to the positioning mechanism 5 moves synchronously to the corresponding position. The controller 3 controls the stepper motor 83 to drive the bolt 84 to connect with the nut 521 on the first slider 52, locking the first slider 52 to maintain stable positioning. Subsequently, the Y-axis of the three-axis platform 2... The axis moving platform 23 drives the first gripper 4 to grip the condenser bracket from the second area 22 and move it to the corresponding connection position of the car condenser in the first area 21. During this process, the first pressure sensor 41 on the first gripper 4 detects the clamping pressure in real time and transmits the signal to the controller 3 to ensure that the clamping force is appropriate. At the same time, the controller 3 controls the third slider 62 on the gantry 6 to move along the third slide groove 61, driving the pipe clamping mechanism 7 to adjust to the position that matches the connection of the car condenser pipe. The cylinder 71 drives the second gripper 72 to clamp the pipe and align it with the car condenser in the first area 21. The second pressure sensor 721 on the second gripper 72 transmits the detected pipe clamping pressure signal to the controller 3. The controller 3 fine-tunes the clamping force according to the pressure signal. Finally, under the coordination of the controller 3, the precise connection operation of the car condenser, condenser bracket and pipe is completed.

[0041] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
