The plurality of clamping jaws 42 are provided on one vertical surface of the vertical clamp body 41. The plurality of clamping jaws 42 fix the water-cooling plate B vertically to the vertical clamp body 41 in a clamping state.

[0045] The servo movable fixture carrier 50 includes a servo movable mechanism 51 and a fixture carrier 52. The fixture carrier 52 is disposed at the output end of the upper surface of the servo movable mechanism 51. The servo movable mechanism 51 is specifically an XY two-axis servo movable mechanism. It enables the water cooling plate B to be reliably moved to be arranged directly below the lower convex joint 333 of the lower seat 332 of the floating head 33 when assembling the faucet A.

The center of the top plate 21 is fixed with a vertical cylinder body of a servo cylinder 31. The lower output end of the servo cylinder 31 passes through the top plate 21 and convex downward. The lower output end of the servo cylinder 31 is connected to a horizontal connecting plate 60. Two sets of guide rods 61 and a linear bearing mechanism 62 are provided between the horizontal connecting plate 60 and the top plate 21. The two sets of guide rods 61 and the linear bearing mechanism 62 are arranged on the servo cylinder 31. Arranged on both sides of the cylinder, two sets of guide rods 61 and linear bearing mechanisms 62 ensure reliable and stable vertical lifting of the horizontal connecting plate. A rotation direction adjuster 32 is installed at the lower part of the horizontal connecting plate 60. The lower output end of the rotation direction adjuster 32 is fixedly connected to the upper seat 331 of the floating head 33.

[0052] A method for using a water pipe press-fitting device, see Figure 1-Figure 5 , which includes the following steps:

[0053] S1. Turn on the device, set the pressure parameters and judgment parameters through the human-machine interface 90, switch to the automatic state, the status light 80 turns yellow, and the device is in standby state;

[0054] S2. Place the water-cooling plate B into the vertical fixture body 41 and secure it with the clamping jaws 42;

[0055] S3. Place the water nozzle A1 onto the lower convex joint 333 at the bottom of the floating head 33. Press the double-handed start button 100 to activate the clamping device. The clamping jaws 42 clamp the water cooling plate. The servo movement mechanism 51 drives the clamp carrier 52 and the clamp assembly 40 to move precisely to the bottom of the floating head 33.

[0056] S4: The servo cylinder 31 receives a downward pressure signal, and then automatically drives the floating head 33 to move downward, pressing the nozzle A1 into the corresponding hole of the water cooling plate B within the set pressure range;

[0057] S5. After the water nozzle A1 is pressed in, the servo cylinder 31 drives the floating head 33 to rise;

[0058] S6. The servo moving mechanism 51 moves again, aligning the second hole of the water-cooling plate B with the floating head 33. The water nozzle A2 is placed on the lower convex joint 333 at the bottom of the floating head 33. The press-fitting is continued, and step S4 is repeated to press the water nozzle A2 in.

[0059] S7, the servo cylinder 31 drives the floating head 33 to rise, the servo moving mechanism 51 drives the fixture carrier 52 back to the starting position, the clamping jaws 42 open, and the water cooling plate B with the water nozzle A pressed in is taken out;

[0060] S8. Continue to put down a water-cooling plate B, and repeat steps S3 to S7.

[0061] The servo end of the servo cylinder 31 is externally connected to the judgment module, and the judgment module is built into the processor of the human-machine interface 90. The judgment module outputs the judgment result to the human-machine interface 90. The human-machine interface 90 is also provided with a parameter control module. During the pressing process, the judgment module detects the pressure and stroke curve of the servo cylinder 90. If it is found that it exceeds the set curve range, it will be judged as NG, the pressing will be ended, reset, and the unqualified red light in the pass / fail light 70 will be displayed, and the status light 80 will flash red to give an alarm prompt. On the contrary, if it is OK, the qualified green light in the pass / fail light 70 will be displayed, and the status light 80 will remain unchanged.

[0062] When there is a position error state, see Figure 4 : The lower end of the water nozzle A is close to the hole of the water cooling plate B, and then the lower end of the water nozzle A contacts the cross-sectional surface of the hole. Then the lower seat 332 is translated relative to the upper seat body 331 to correct the position error, and then a reliable press-fitting operation is performed, and the corrected translation deviation is within 2mm.

[0063] When there is an angle error state, see Figure 5 : When there is an angle error, the lower end of the water nozzle A approaches the hole of the water cooling plate B. When the lower end of the water nozzle A reaches one side of the hole, it moves along the chamfered surface of the hole. When the lower end of the water nozzle A reaches the other side of the hole, due to the reaction force, the lower seat 332 deflects the correction angle relative to the upper seat body 331, and then a reliable press-fitting operation is performed, and the correction angle deviation is within 3°.

[0064] The beneficial effects of the utility model are as follows:

[0065] 1) The use of automated assembly technology not only saves a lot of manpower, but also saves a lot of time; it can effectively avoid misjudgment caused by manual work;

[0066] 2) The productivity, quality, precision and efficiency of the utility model are greatly improved, energy consumption is effectively saved, and the process is streamlined; the processing, control and use are simple.

[0067] 3) The water-cooling plate clamping method of this utility model can be equipped with manual or automatic clamping and fastening methods. The pressing process is monitored and pressure-displacement acquisition equipment is used to detect the pressure-displacement curve of the entire pressing process for evaluation. The water pipe and water-cooling plate are positioned by a floating head, so that product processing tolerances and any deviations in the position of the pressure head and the hole can be reliably corrected.

[0068] 4) You can choose according to the specific requirements of the water cooling plate and water pipe: constant pressure pressing, constant distance pressing.
