It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0026] Embodiment 1: An adjustable riveting device, see Figure 1-Figure 3As shown, it includes a support frame 1, a workbench 2, a first fixing frame 3, a cylinder 4, a pressing plate 5, a porous plate 13, an angle plate 14, a fixing sleeve 15, a rivet joint 16 and a driver 17. The support frame 1 is provided with a workbench 2 by bolt connection, the first fixing frame 3 is provided with a bolt connection on the workbench 2, the cylinder 4 is provided with a bolt connection on the top of the first fixing frame 3, the push rod of the cylinder 4 faces downward, the pressing plate 5 is fixedly connected to the push rod of the cylinder 4 by bolt connection, a porous plate 13 is provided on one side of the workbench 2 by bolt connection, the porous plate 13 is plugged with an angle plate 14, and the angle plate 14 can be plugged into the porous plate At different positions of 13, a fixing sleeve 15 is slidably provided on the angle plate 14, and the fixing sleeve 15 slides up and down along the angle plate 14. A driver 17 is installed on the other side of the workbench 2 by bolt connection, and a rivet joint 16 is provided on the driver 17. It also includes a mounting plate 6, a fixing pad 7 and a fixing clamp 8. A mounting plate 6 is installed on the workbench 2 by bolt connection, and two fixing pads 7 are plugged into the mounting plate 6. Two fixing clamps 8 for clamping the piston rod are slidably provided on the two fixing pads 7. Two fixing clamps 8 for clamping the piston rod are also slidably provided on the pressure plate 5. The four fixing clamps 8 all slide horizontally, and the four fixing clamps 8 cooperate to clamp the piston rod.

[0027] See also Figure 3 As shown, there are also two clamping plates 11 slidably arranged on both sides of the second fixing frame 10. The clamping plates 11 slide laterally along the second fixing frame 10. A pressure spring 12 is wound around the clamping plates 11. The pressure spring 12 pushes the clamping plates 11 to engage with the fixing fixture 8. A bidirectional screw 9 is threadedly arranged on the two second fixing frames 10 on the same horizontal plane.

[0028] When it is necessary to rivet the piston rod and the piston cap, place the piston rod on the fixing fixture 8, and make the end with the rivet face the rivet joint 16. According to the length of the piston rod, the angle plate 14 can be inserted into different positions of the porous plate 13, so that the end of the piston rod away from the rivet fits on the fixing sleeve 15, and then the cylinder 4 is started to push the pressure plate 5 downward, and the fixing fixture 8 on the pressure plate 5 cooperates with the two fixing fixtures 8 on the two fixing pads 7 to clamp and fix the piston rod, and then the driver 17 is started to rotate and push out the rivet joint 16. The rivet joint 16 applies pressure to the rivet, embeds the rivet into the piston rod, and rivets the piston cat to the piston rod; when the diameters of the piston rod are different, the upper and lower two-way screws 9 are rotated at the same time to make the upper two fixing fixtures 8 slide laterally along the pressure plate 5, and the lower two fixing fixtures 8 slide laterally along the pressure plate 5. The fixed clamp 8 slides laterally along the two fixing pads 7, thereby adjusting the spacing between the fixing clamps 8. When each fixing clamp 8 clamps the piston rod, the fixing clamp 8 fits the piston rod more closely, making the fixation of the piston rod more stable. The two fixing clamps 8 can also be slid off the two fixing pads 7 and the fixing pads 7 can be replaced to adjust the height of the fixing clamp 8 so that the center of the piston rod can be aligned with the riveted head 16 during riveting. When necessary, the clamps 11 on both sides can be pulled to slide along the second fixing frame 10 toward the side away from each other. At this time, the pressure spring 12 is compressed and deformed by force to disengage the clamp 11 from the clamping connection with the fixing clamp 8. After replacing the new fixing clamp 8, the clamp 11 is loosened, and the pressure spring 12 returns to its original state and pushes the clamp 11 to clamp and fix the fixing clamp 8.

[0029] Example 2: Based on Example 1, refer to Figure 4 and Figure 5 As shown, it also includes a water tank 18 installed at the bottom of the workbench 2 by bolt connection, and a water inlet pipe 22 is connected to and communicated with the water tank 18, and the water inlet pipe 22 penetrates the workbench 2, and a semiconductor refrigeration module 19 is installed at the bottom of the water tank 18 by bolt connection. Two water pipes 21 are connected to and communicated with the water tank 18, and the two water pipes 21 are connected together and communicated with a sleeve 23, and the sleeve 23 is sleeved on the riveted joint 16. The sleeve 23 uses a heat-resistant and highly thermally conductive material, which can absorb the heat generated by the riveted joint 16 and prevent the sleeve 23 from being burned. The sleeve 23 contacts the riveted joint 16 but is not fixedly connected. A micro water pump 20 is installed in the water tank 18 by bolt connection, and the micro water pump 20 is connected to a water pipe 21.

[0030] When the riveted joint 16 works for a long time, a large amount of heat will be generated by the riveted joint 16. At this time, the semiconductor refrigeration module 19 and the micro water pump 20 are started. The semiconductor refrigeration module 19 cools and cools the water in the water tank 18. The micro water pump 20 inputs the water in the water tank 18 into the sleeve 23 through the water pipe 21. The heat on the riveted joint 16 is absorbed by the water in the sleeve 23. The water in the sleeve 23 flows back to the water tank 18 through another water pipe 21. This reciprocating cycle is repeated to continuously cool the riveted joint 16.

[0031] See also Figure 6 As shown, it also includes a support seat 2401 installed on the side of the porous plate 13 by welding, and a fixed screw 24 is rotatably provided on the support seat 2401. A sliding rod 25 is fixedly connected to the fixed sleeve 15 by welding, and the sliding rod 25 is threadedly connected to the fixed screw 24.

[0032] When the diameters of the piston rods to be riveted are different, in order to make the fixed sleeve 15 better fit the center of the piston rod, the sliding rod 25 is rotated so that the sliding rod 25 drives the fixed sleeve 15 to slide up and down along the angle plate 14 so that the fixed sleeve 15 is aligned with the center of the piston rod.

[0033] See also Figure 7 As shown, the trough plate 26 further includes two clamping blocks 27 installed at the bottom of the trough plate 26 by means of bolt connection, and the trough plate 26 is plugged onto the porous plate 13 via the two clamping blocks 27 .

[0034] Since the staff are accustomed to stacking the piston rods on the workbench 2 after riveting the piston rods, so as to check whether the riveting points are qualified at one time, the piston rods can be placed in the grooves of the groove plate 26, so that the arrangement is more neat, the inspection is more detailed and accurate, and it is not easy to miss. Since the groove plate 26 is plugged into the porous plate 13 through the clamping block 27, different groove plates 26 can be quickly replaced to place piston rods of different numbers or different diameters.

[0035] See also Figure 1 and Figure 4 As shown, a dust cover 28 is slidably provided on the water inlet pipe 22, and a protective shell 29 is installed on the top of the first fixing frame 3 by bolt connection, and the protective shell 29 is sleeved on the outside of the cylinder 4. The dust cover 28 can prevent dust and other foreign matter from falling into the water tank 18 from the water inlet pipe 22 to avoid blockage, and the protective shell 29 is used to protect the cylinder 4 to prevent the cylinder 4 from being damaged by bumps.
