Description

Technical Field

[0001] The invention relates to the technical field of automobile radiator press-assembly, in particular to an automobile radiator press-assembly device and a press-assembly method. Background Art

[0002] It mainly refers to mechanical equipment used to press radiator components onto the radiator body accurately and firmly. This device usually has the characteristics of high precision, high efficiency and high stability to ensure the quality and performance of the radiator during the production process. The press-fitting device of the automobile radiator is mainly used to press the key components in the radiator core.

[0003] In the prior art, when components are press-fitted, the components to be press-fitted are usually placed in a press-fitting area, and then the press-fitted components are press-fitted through a press head. When the components are press-fitted to a set position, the equipment will hold the pressure for a set holding time. After the holding time is over, the press head will automatically return to the starting position. When multiple components need to be press-fitted, the staff is required to adjust the position of the components after each press-fitting is completed to ensure the normal operation of the press-fitting operation.

[0004] During press-fitting, it is usually necessary to press-fit the upper water chamber component, the lower water chamber component and the aluminum core component together. After completing the press-fitting of the upper water chamber component and the aluminum core component, it is often necessary to readjust the distance and alignment between the entire components to ensure that there is no misalignment between the components during the press-fitting process, resulting in press-fitting failure. During the adjustment process, the staff is required to manually adjust the alignment, which not only wastes the entire press-fitting time, but also some subtle angles cannot be detected when the alignment is manually adjusted, resulting in the final press-fitting failure, making the final formed car radiator a defective product that cannot be put into use.

[0012] Preferably, a connecting plate is provided on the fan-shaped plate, and a hydraulic rod is provided on a side of the connecting plate close to the press-fitting seat, and a press-fitting plate is provided on a side of the hydraulic rod away from the connecting plate.

[0014] Preferably, the sliding plate is provided with supporting blocks in a row, and a pushing rod is provided on the supporting blocks, a clamping block is provided at one end of the pushing rod away from the supporting blocks, and a third spring is sleeved on the outside of the pushing rod.

[0015] The present invention also provides a method for using a car radiator press-fitting device, the purpose of which is to take advantage of the prior art in accurately conveying components during the press-fitting process. After completing the press-fitting of one part, the next part of the components can be immediately conveyed to a designated position. At the same time, the components will not be shaken during the conveying process, so that a lot of time can be saved in the entire press-fitting process.

[0016] To achieve the above object, the present invention provides the following technical solution: a press-fitting device and press-fitting method for an automobile radiator, comprising the following steps:

[0017] First, when placing the water chamber component, place the water chamber component on the sliding plate, and limit and clamp the four corners of the water chamber component under the action of the clamping block and the third spring, and then open one of the fan-shaped plates through the handle, so that the staff can place the aluminum core component in the clamping plate;

[0018] After adjusting the position of the aluminum core component, the handle is then turned in the opposite direction to continuously reduce the spacing between the fan-shaped plates. The telescopic plate will be squeezed by the aluminum core component, so that the clamping rod on the telescopic plate and the inclined groove on the clamping plate cooperate to push the clamping plate to continuously approach the side wall of the aluminum core component, and finally form a stable clamping.

[0019] After the clamping is completed, the hydraulic rod is started to press down through the control panel to drive the pressing plate to press down the aluminum core sub-component. After being squeezed by the downward pressure, the aluminum core sub-component can be press-fitted between the upper water chamber component. After the press-fitting is completed, the hydraulic rod is reset. The reset of the hydraulic rod can enable the U-shaped plate to lift the protective bin under the action of the compression spring, so that the clamping plate drives the pressed component to detach from the sliding plate.

[0020] Finally, when the pressed parts are detached from the sliding plate, the servo motor and the starting motor are started simultaneously through the control panel, wherein the servo motor will drive the entire protective bin and the clamping plate to rotate. During the rotation, the locking state between the locking block and the engaging block is released. After the rotation is completed, the engaging block and the locking block are locked again, and the start of the starting motor will drive the transmission belt on the limit shaft to rotate. The rotating transmission belt can swap the positions of the two sliding plates, so that the sliding plate with the lower water chamber component placed can be moved to the bottom of the aluminum core component, and then the hydraulic rod is started to complete the press-fitting between the remaining lower water chamber components and the aluminum core components.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention replaces the cooperation between the two sliding plates and the transmission belt on the assembly. After completing the partial press-fitting, the position between the two sliding plates is replaced by the transmission belt to supplement the components. As a result, after the sliding plates are replaced, the position of the entire component will remain within the area of ​​the current press-fitting position and will not change. At the same time, the position limitation of the component in the entire alignment method will prevent the component from being offset, so that the entire press-fitting process can reduce the generation of defective products.

[0023] 2. At the same time, during the press-fitting process, the U-shaped plate can cooperate with the compression spring to buffer the pressure applied by the press-fitting plate to a certain extent. Under this buffering effect, the initial pressure can be partially relieved, so that there is enough buffer time for the press-fitting between the components. The press-fitted components will not be damaged at the interface between the press-fitted components due to excessive pressure, resulting in the scrapping of the entire product. At the same time, the clamping plate can stably clamp the aluminum core components to prevent the aluminum core components from shaking, which will cause the press-fitted components to be unable to align and make the final formed components unable to be put into use;

[0024] 3. After the press-fitting between some components is completed, the rise of the hydraulic rod can make the compression spring arranged under the U-shaped plate release its stored kinetic energy to push the aluminum core component up, and disengage the sliding plate from the clamping effect of the component. After the disengagement, it is convenient to replace the position between the two sliding plates, so that the replacement between the sliding plates will not fail due to the obstruction of the components. After the U-shaped plate is pushed, it will be able to drive the whole to flip through the set servo motor, so as to facilitate the subsequent press-fitting operation.

[0025] 4. The clamping blocks set on the sliding plate can quickly position the four corners of the components, and can also play a role in straightening the components during the positioning process, avoiding shaking of the components when the transmission belt carries the sliding plate to replace the position, resulting in position deviation. The straightened components can be directly pressed after the sliding plate moves to the predetermined position, without the need for secondary adjustment, saving a lot of time and improving the efficiency of the entire press-fitting.

[0048] A second spring 55 is sleeved on the support rod 54, and the second spring 55 is used to reset the telescopic plate 52. The telescopic plate 52 is symmetrically provided with a locking rod 521, and the clamping plate 53 is symmetrically provided with an inclined groove 531, and the inclined groove 531 and the locking rod 521 are engaged and slidable. The sliding relationship between the locking rod 521 and the inclined groove 531 is used to drive the two clamping plates 53 to move toward each other after the telescopic plate 52 is squeezed by the aluminum core component 8, thereby clamping the aluminum core component 8.

[0049] During use, after one of the fan-shaped plates 12 is opened by the handle 16, it is convenient for the staff to clamp the aluminum core sub-component 8. After the aluminum core sub-component 8 is adjusted to a good position, as the handle 16 is turned in the opposite direction to continuously reduce the spacing between the fan-shaped plates 12, the telescopic plate 52 will be squeezed by the aluminum core sub-component 8, thereby through the cooperation between the locking rod 521 on the telescopic plate 52 and the inclined groove 531 on the clamping plate 53, the clamping plate 53 is pushed to continuously approach the side wall of the aluminum core sub-component 8, and finally a stable clamping is formed. After the clamping is completed, the hydraulic rod 14 is started to drive the pressing plate 141 to apply pressure to the aluminum core sub-component 8 to press the aluminum core sub-component 8 and the upper water chamber component 9 together. After the pressing is completed, the resetting of the hydraulic rod 14 can make the entire pressed component detach from the sliding plate 33, thereby rotating, and pressing the lower water chamber component 10 on the other end of the aluminum core component 8.

[0050] The remaining structures are the same as those of Example 1. Example

[0051] See also Figures 1 to 10 , which is the third embodiment of the present invention. This embodiment is different from the first and second embodiments in that:

[0052] The sliding plate 33 is provided with supporting blocks 331 in a row, and the supporting blocks 331 are provided with pushing rods 332, the pushing rods 332 are used to support the clamping blocks 333, and the pushing rods 332 are provided with clamping blocks 333 at one end away from the supporting blocks 331, the clamping blocks 333 are in an L shape, and the clamping blocks 333 have a certain bending angle, so that the water chamber components can be easily placed therein, and the four corners of the water chamber components are limited by the clamping blocks 333 to prevent the water chamber components from shaking, and the outer sleeve of the pushing rod 332 is provided with a third spring 334, the third spring 334 is used to provide elastic force to facilitate the clamping blocks 333 to clamp the water chamber components firmly.

[0053] During use, when the water chamber component needs to be placed, the water chamber component is placed on the sliding plate 33. When the four corners of the water chamber component are limited and clamped by the clamping block 333, it can be ensured that the water chamber component will not shake. During the entire placement process, when the clamping block 333 limits the four corners of the water chamber component, the position of the water chamber component can also be adjusted. The adjusted water chamber component can complete the press-fitting operation with the aluminum core component 8. After the press-fitting is completed, the rise of the aluminum core component 8 can drive the water chamber component to rise synchronously and disengage from the clamping block 333. During the disengagement process, the opening of the clamping block 333 opens toward the outside of the water chamber component. Therefore, the clamping block 333 will not block the water chamber component during the entire process.

[0054] The remaining structures are the same as those of embodiments 1 and 2. Example

[0055] See also Figures 1 to 4 , which is the fourth embodiment of the present invention, and which provides: a press-fitting device and press-fitting method for an automobile radiator, comprising the following steps:

[0056] S1, when placing the water chamber component, first place the water chamber component on the sliding plate 33, and limit and clamp the four corners of the water chamber component under the action of the clamping block 333 and the third spring 334, and then open one of the fan-shaped plates 12 through the handle 16, so that the staff can place the aluminum core component 8 in the clamping plate 53;

[0057] S2, after adjusting the position of the aluminum core component 8, the handle 16 is then turned in the opposite direction to continuously reduce the spacing between the sector plates 12, and the telescopic plate 52 is squeezed by the aluminum core component 8, so that the clamping rod 521 on the telescopic plate 52 cooperates with the inclined groove 531 on the clamping plate 53, pushing the clamping plate 53 to continuously approach the side wall of the aluminum core component 8, and finally forming a stable clamping;

[0058] S3, after the clamping is completed, the hydraulic rod 14 is started to press down through the control panel 6 to drive the pressing plate 141 to press down the aluminum core sub-component 8. After being pressed down, the aluminum core sub-component 8 can be press-fitted between the upper water chamber component 9. After the press-fitting is completed, the hydraulic rod 14 is reset. The reset of the hydraulic rod 14 can enable the U-shaped plate 43 to lift the protective bin 7 under the action of the compression spring 44, so that the clamping plate 53 drives the pressed component to detach from the sliding plate 33;

[0059] S4. Finally, when the pressed component is detached from the sliding plate 33, the servo motor 73 and the starting motor 38 are started simultaneously through the control panel 6, wherein the servo motor 73 will drive the entire protective bin 7 and the clamping plate 53 to rotate 180 degrees. During the rotation, the locking state between the set locking block 71 and the engaging block 433 is released. After the rotation is completed, the engaging block 433 and the locking block 71 are locked again. The start of the starting motor 38 will drive the transmission belt 36 on the limit shaft 37 to rotate. The rotating transmission belt 36 can swap the positions of the two sliding plates 33, so that the sliding plate 33 with the lower water chamber component 10 placed can be moved to the bottom of the aluminum core component 8, and then the hydraulic rod 14 is started to complete the press-fitting between the remaining lower water chamber components 10 and the aluminum core component 8.
