[0001] This utility model belongs to the field of press-fitting tooling technology, and specifically relates to a press-fitting indentation control device for water pipes of oil coolers. Background Technology

[0002] Currently, for press-fitting interfaces on irregular surfaces, the general approach is to pre-position and fix the workpiece, and then press the interface to be pressed onto the workpiece interface. Existing press-fitting tools use the method of pressing the workpiece down to the end of the water pipe for installation. However, when the finished product obtained after press-fitting using this method is pulled out for inspection, it is found that the entire circumference of the indentation after the water pipe is pulled out only reaches 50% to 60%, which poses a risk of water leakage and subsequent safety hazards. At the same time, the part to be pressed is heavy, and the negative pressure of the main body of the device is too large during the pressing process, which is prone to wear. Utility Model Content

[0032] To resolve the above issues, please refer to [link / reference]. Figures 1 to 4 This utility model provides a pressure-fitting and indentation control device for water pipes in an oil cooler, comprising a main body 1, a floating device 2, and a positioning and clamping assembly 3. The main body 1 includes a pressure plate 11 and a base plate 12. A floating support 4 is provided between the base plate 12 and the pressure plate 11. The pressure plate 11 moves along the length of the floating support 4 in a direction away from and towards the base plate 12. One end of the floating device 2 is provided with a boss 5 for fitting a water pipe joint. The end of the floating device 2 away from the boss 5 is connected to the surface of the pressure plate 11 facing the base plate 12. The positioning and clamping assembly 3 is disposed on the base plate. Facing the surface of the pressure plate 11, the positioning and clamping assembly 3 includes a positioning support 31 and a clamping part 32. The positioning support 31 and the clamping part 32 are arranged along the length direction of the main body 1 of the device. The clamping part 32 has a movable pressure block 321. The movable pressure block 321 moves toward or away from the positioning support 31 and encloses to form a clamping space. The workpiece to be pressed is positioned on the positioning support 31 and the position of the workpiece to be pressed is restricted. The movable pressure block 321 presses the workpiece to be pressed into the clamping space. The positioning support 31 is in contact with the periphery of the workpiece to be pressed.

[0033] In optional embodiments, such as Figure 1As shown, the positioning support 31 includes a first limiting plate 311, a first support base 312, and a second support base 313. A plurality of contour blocks 314 and a plurality of positioning pins 315 are provided on one surface of the first limiting plate 311. The surface of the first limiting plate 311 with the contour blocks 314 and the positioning pins 315 faces the movable pressure block 321. The first support base 312 and the second support base 313 are disposed between the first limiting plate 311 and the movable pressure block 321. Specifically, the first limiting plate 311, the first support base 312, and the second support base 313 are all vertically arranged with the connecting base 33. The first limiting plate 311 and the first support base 312 are arranged parallel to each other. The contour block 314, the first support base 312, and the second support base 313 all have arc-shaped surfaces that conform to the appearance of the workpiece with the connecting pipe. In this embodiment, there are three contour blocks 314 and two positioning pins 315. The positional distribution of the contour blocks 314 and the positioning pins 315 is consistent with the appearance and hole positions of the workpiece to be pressed. There are two first support bases 312. The two first support bases 312 are parallel and spaced apart. The heights of the two first support bases 312 are different. The height of the first support base 312 closer to the first limiting plate 311 is lower than the height of the other first support base 312. The second support base 313 is located directly below the boss 5.

[0034] In optional embodiments, such as Figure 1 and Figure 2 As shown, the positioning and clamping assembly 3 also includes a connecting base 33, which is connected to the base plate 12 and arranged in parallel, for mounting the positioning support part 31 and the clamping part 32. Specifically, the connecting base 33 is plate-shaped, and a positioning post 122 is provided on the surface of the base plate 12 facing the pressure plate 11. A slot is opened on the corresponding surface of the connecting base 33, and the connecting base 33 is connected to the base plate 12 by engaging the positioning post 122 in the slot. The positioning connection between the connecting base 33 and the base plate 12 improves the accuracy of connecting the workpiece to be pressed and the water pipe to be connected.

[0035] In optional embodiments, such as Figure 2 As shown, a first reinforcing rib 34 is provided between the first limiting plate 311 and the connecting base 33. The first reinforcing rib 34 is connected to the surface of the first limiting plate 311 facing away from the contour block 314. By providing the first reinforcing rib 34, the connection stability between the first limiting plate 311 and the connecting base 33 is improved, preventing the first limiting plate 311 from shaking. At the same time, the connecting base 33 is provided with a limiting post 331, and the first limiting plate 311 is provided with a corresponding groove 316, which limits the installation position 121 of the first limiting plate 311. This further restricts the position of the workpiece to be pressed, and the workpiece to be pressed can be accurately aligned with the water pipe to be connected, realizing accurate connection of the workpiece to be pressed.

[0036] In optional embodiments, such as Figure 2 As shown, the connecting base 33 is also provided with a second limiting plate 35, which is used to install the clamping part 32. A second reinforcing rib 351 is provided between the second limiting plate 35 and the connecting base 33. The second reinforcing rib 351 is provided on the surface of the second limiting plate 35 facing the first limiting plate 311. The second limiting plate 35 is arranged parallel to the first limiting plate 311. The second reinforcing rib 351 improves the stability of the second limiting plate 35, and the position of the second reinforcing rib 351 does not obstruct the setting of the first driving cylinder 322.

[0037] In optional embodiments, such as Figure 2 As shown, the pressing part 32 also includes a first driving cylinder 322. One end of the first driving cylinder 322 is connected to the second limiting plate 35, and its driving end is driven to connect to the movable pressing block 321. Specifically, the second limiting plate 35 has a hole for the peripheral side of the first driving cylinder 322 to be connected to the hole wall, or the end face of the first driving cylinder 322 with the driving end is connected to the surface of the second limiting plate 35 opposite to the first limiting plate 311, and its driving end passes through the hole to connect to the movable pressing block 321. Furthermore, in order to protect the surface of the workpiece to be pressed, a nylon layer 323 is provided on the surface of the movable pressing block 321 to avoid scratches on the workpiece surface.

[0038] In optional embodiments, such as Figure 2 As shown, a magnetic element 51 is provided around the protrusion 5 for magnetically adsorbing the water pipe to be connected. Specifically, the floating device 2 is connected to the pressure plate 11 via a floating connecting plate. The surface of the floating device 2 facing the bottom plate 12 is connected to the pressure head 6 via a flange. The end of the pressure head 6 facing the bottom plate 12 has a gradually tapering diameter. One end of the protrusion 5 is connected to the tapering end of the pressure head 6, and the other end is set towards the bottom plate 12. In practical applications, the end of the water pipe to be connected is provided with a metal part. After the water pipe to be connected is fitted with the protrusion 5 with a clearance, the protrusion 5 is further stably connected to the water pipe to be connected by the magnetic adsorption element, which is a magnet.

[0039] In optional embodiments, such as Figure 1 , Figure 3 and Figure 4As shown, the floating support 4 includes a guide post 41, a spring 42, and a linear bearing 43. One end of the guide post 41 is connected to the base plate 12, and the linear bearing 43 is connected to the pressure plate 11. The linear bearing 43 is sleeved on the periphery of the guide post 41, and the spring 42 is sleeved on the periphery of the guide post 41, with both ends abutting against the linear bearing 43 and the base plate 12 respectively. Specifically, the linear bearing 43 is driven by a second drive cylinder 44, which moves it along the length of the guide post 41, thereby moving the pressure plate 11 and the floating device 2 toward the base plate 12. The water pipe to be installed approaches the workpiece to be pressed and is installed. After installation, the floating device 2 moves away from the base plate 12. Furthermore, the base plate 12 has an installation position 121 for installing the second drive cylinder 44. In this embodiment, two floating support 4s are provided and arranged opposite each other.

[0040] In optional embodiments, such as Figure 1 As shown, a limiting cover 45 is provided at the other end of the guide post 41. The length and width of the limiting cover 45 are both greater than the diameter of the guide post 41, which can limit the range of motion of the linear bearing 43 and prevent the linear bearing 43 from detaching from the guide post 41.

[0041] In optional embodiments, such as Figure 2 As shown, it also includes a control valve body, which is disposed on the surface of the pressure plate 11 facing the base plate 12, and is used to control the operation and speed of the floating device 2. Specifically, the control valve body includes an L-shaped speed regulating valve 7 and a mechanical valve 8. The mechanical valve 8 is connected to the second drive cylinder 44 and controls the operation of the second drive cylinder 44. At the same time, the L-shaped speed regulating valve 7 adjusts the descent speed of the pressure plate 11, so that the water pipe to be connected is connected to the workpiece to be pressed, thereby improving the degree of pressing of the water pipe.

[0042] In use, the control device is installed and fixed on the worktable of the pneumatic press. Simultaneously, the first drive cylinder 322 and the second drive cylinder 44 are connected to an air source via connectors. The water pipe to be connected is then sleeved and adsorbed onto the periphery of the boss 5. The workpiece to be pressed is placed on the first support base 312, the second support base 313, and the first limiting plate 311. The first drive cylinder 322 drives the movable pressing block 321 to move towards the first limiting plate 311, thereby cooperating with the positioning support part 31 to stably clamp the workpiece to be pressed within the enclosed shape. Within the clamping space; then, the second drive cylinder 44 is activated, causing the linear bearing 43 to move along the length of the guide post 41 toward the direction closer to the base plate 12, driving the pressure plate 11 and the floating device 2 to press down. During the descent, the end of the water pipe to be connected is floated and positioned with the hole of the workpiece to be pressed through the floating device 2, so that the end of the water pipe to be connected floats and aligns with the hole of the workpiece to be pressed. The end of the water pipe to be connected is pressed into the workpiece to be pressed, thus completing the pressing of the water pipe to be connected. The pneumatic press is then restored, and the pressure plate 11 moves up to the initial position.

[0043] In summary, this control device features a positioning and clamping assembly 3 on the base plate 12 to limit the installation of the workpiece to be pressed. The positioning and clamping assembly 3 is positioned and installed between itself and the base plate 12. After the workpiece is placed on the positioning support 31, it is clamped by the clamping part 32, ensuring that the boss 5 of the floating device 2 corresponds to the workpiece. During the pressing process, the positioning and clamping assembly 3 restricts the displacement of the workpiece, ensuring that the water pipe to be connected corresponds to the pressing position of the workpiece, thus cooperating with the floating device 2 to perform the pressing work, extending the pressing depth, and improving the pressing effect. The positioning and clamping assembly 3 can quickly position and place the workpiece to be pressed, improving work efficiency.
