Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts assembly, in particular to a radiator water chamber press assembly machine. Background Art

[0002] The radiator water chamber is a device used to dissipate heat from the coolant in the car, and is an important part of the cooling system in the car. Figure 6 It is mainly composed of an upper water chamber, a lower water chamber and multiple heat exchange tubes in the middle, wherein the upper water chamber and the lower water chamber are each provided with multiple groups of water inlets for connecting the heat exchange tubes. During installation, in order to ensure the sealing between the heat exchange tubes and the upper and lower water chambers, it is necessary to install rubber sealing sleeves on the upper and lower ends of the heat exchange tubes, and then insert the upper and lower ends of the heat exchange tubes into the multiple groups of water inlets of the upper water chamber and the lower water chamber respectively, and then apply pressure to the upper water chamber and the lower water chamber through a pressing device to press the heat exchange tubes tightly onto the upper water chamber and the lower water chamber.

[0003] In the prior art, a utility model patent with patent application number 201921461994.1 discloses a press-fitting device, which is mainly composed of a servo press, a floating unit, a connecting plate and a pressure head unit. When press-fitting an object to be pressed, the object to be pressed is placed under the pressure head unit, and then the pressure head unit is lowered to apply downward pressure to the object to be pressed. The inventor believes that there are the following problems during use. When press-fitting an object with a longer length, such as a radiator water chamber, it can only apply downward pressure locally on the object to be pressed, which can easily lead to uneven force on various parts of the object to be pressed, which can easily lead to skewed press-fitting and inconvenient use. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a radiator water chamber press machine which can apply pressure to the left and right parts of the upper water chamber at the same time, so that the force on the upper water chamber is more uniform, ensuring the accuracy of the press-fitting process, and is easy to use and highly practical.

[0005] The radiator water chamber press-fitting machine of the utility model includes a bottom plate and a support plate. The support plate is fixedly installed at the upper end of the bottom plate. It further includes a clamping mechanism, a distance adjustment mechanism, and two sets of downward pressure mechanisms. The clamping mechanism is installed at the upper end of the support plate and has the function of clamping and fixing. The two sets of downward pressure mechanisms are installed on the distance adjustment mechanism. The distance adjustment mechanism is used to adjust the distance between the two sets of downward pressure mechanisms. The two sets of downward pressure mechanisms are both located above the clamping mechanism and have the function of applying downward pressure. When assembling the radiator water chamber, first place the lower water chamber on the clamping mechanism for clamping and fixing. Then, insert the lower parts of multiple heat exchange tubes into multiple water ports on the lower water chamber respectively. After that, place the upper water chamber on the upper ends of the multiple heat exchange tubes, so that the upper parts of the multiple heat exchange tubes are inserted into multiple water ports on the upper water chamber respectively. Then, apply downward pressure to the left and right parts of the upper water chamber simultaneously through the two sets of downward pressure mechanisms, so that the upper water chamber applies pressure to the lower water chamber through the heat exchange tubes, and the upper and lower parts of the heat exchange tubes are respectively inserted tightly into multiple groups of water ports on the upper and lower water chambers. When press-fitting the radiator water chamber, it can apply pressure to the left and right parts of the upper water chamber simultaneously, and the force on the upper water chamber is more uniform, ensuring the accuracy during the press-fitting process, being convenient to use and having high practicality.

[0006] Preferably, the clamping mechanism includes a support plate, a lead screw, and two sets of clamping plates. The support plate is fixedly installed at the upper end of the support plate. The lead screw is rotatably installed on the support plate. The left and right parts of the lead screw are respectively provided with external threads with opposite helix directions. The two sets of clamping plates are respectively screwed onto the left and right parts of the lead screw. The two sets of clamping plates are both slidably installed on the support plate in the left-right direction. When assembling the radiator water chamber, first place the upper water chamber between the two sets of clamping plates at the upper end of the support plate. Then, rotate the lead screw. The rotating lead screw drives the two sets of clamping plates to approach each other until the two sets of clamping plates respectively contact the left and right ends of the upper water chamber, and the two sets of clamping plates clamp and fix the upper water chamber. This improves the stability of the upper water chamber during the assembly process.

The support frame is fixedly installed at the upper end of the support plate. The slide rail is fixedly installed on the upper part of the support frame. The servo motor is fixedly installed at the right end of the support frame. The screw rod is rotatably installed on the upper part of the support frame. The left and right parts of the screw rod are respectively provided with external threads with opposite helix directions. The input end of the screw rod is connected to the output end of the servo motor. The two sets of sliding blocks are both slidably installed on the slide rail in the left-right direction. The two sets of sliding blocks are respectively screwed onto the left and right parts of the screw rod. The two sets of downward pressure mechanisms are respectively fixedly installed at the lower ends of the two sets of sliding blocks. When applying pressure to the upper water chamber through the downward pressure mechanism, turn on the servo motor. The servo motor drives the screw rod to rotate. The rotating screw rod adjusts the distance between the two sets of downward pressure mechanisms through the two sets of sliding blocks until the distance between the two sets of downward pressure mechanisms is adapted to the length of the upper water chamber. Since it can adjust the distance between the two sets of downward pressure mechanisms, it can adjust the distance between the two sets of downward pressure mechanisms according to the length of the upper water chamber, being convenient to use and having low limitations.

During the descending process of the pressing plate, it contacts the upper water chamber, and the pressing plate applies a downward pressure to the upper water chamber, which facilitates the press-fitting of the upper water chamber.

[0009] Preferably, it further includes a pressure sensor. The pressure sensor is arranged at the lower end of the push rod. The pressing plate is fixedly installed at the lower end of the pressure sensor. By arranging the pressure sensor at the lower end of the push rod, it facilitates the monitoring of the pressure.

Then, place the upper water chamber 1 on the upper ends of the multiple heat exchange tubes 3, so that the upper parts of the multiple heat exchange tubes 3 are inserted into multiple water ports on the upper water chamber 1 respectively. Then, apply downward pressure to the left and right parts of the upper water chamber 1 simultaneously through the two sets of downward pressing mechanisms, so that the upper water chamber 1 applies pressure to the lower water chamber 2 through the heat exchange tubes 3, and the upper and lower parts of the heat exchange tubes 3 are respectively inserted tightly into multiple groups of water ports on the upper water chamber 1 and the lower water chamber 2.
