The heating tube 70 is located on the rear side of the control box 7.

[0059] Working principle of the present invention: First, use the pedal switch 16 to start the adjustment motor 24, drive the lead screw 23 to rotate, drive the adjustment slider 61 to move forward on the base frame 2, drive the adjustment beam 6 to move forward along the longitudinal guide rail 21 through the adjustment sleeve 60, and when the adjustment beam 6 moves, the support seat 4 is driven to move forward through the support rod 43. The support seat 4 drives the vertical plate 30 and the translation seat 3 through the vertical guide sleeve 42 and the vertical guide rail 32. The translation seat 3 moves forward along the longitudinal guide rail 21 through the longitudinal sleeve 33. The adjustment roller and the translation roller 34 reduce the friction force during movement. In this process, the distance between the adjustment beam 6 and the end beam 20 gradually increases, the inclination angle of the support rod 43 becomes smaller, and the support seat 4 simultaneously descends along the vertical guide rail 32 until the adjustment beam 6 moves. When the end plate 22 is reached, the pedal switch 16 is released, and the regulating motor 24 is turned off. At this time, the supporting seat 4 is in a low position, which is convenient for directly installing the assembly shaft 8, the shaft disc 90 and the impeller bottom plate 91. During installation, the shaft disc 90 and the impeller bottom plate 91 are vertically inserted between the clamping plates 5, and then the assembly shaft 8 is inserted into the shaft disc 90 and passed through the impeller bottom plate 91, and the shaft heads 80 at both ends of the assembly shaft 8 are placed on the supporting position between the two groups of supporting wheels 41 on the bracket 40, and then the position of the impeller bottom plate 91 is adjusted, the rivet holes are aligned, and then the impeller bottom plate 91 is assembled to the shaft disc 90. Under the elastic pressure of the auxiliary spring 45, the sleeves 50 on both sides are squeezed toward the middle along the guide rod 44, so that the clamping plate 5 squeezes the shaft disc 90 and the impeller bottom plate 91 They are pressed together, and pins are used to position and align them in several aligned rivet holes. When the assembly shaft 8 rotates, the mutual rolling of the supporting wheel 41 and the shaft head 80 is used to reduce the friction force on the assembly shaft 8; then the pedal switch 16 is used to control the adjustment motor to rotate in the opposite direction, driving the screw 23 to rotate, and driving the adjustment beam 6 to move backward through the adjustment sleeve 60. During this process, the adjustment beam 6 pushes the support seat 4 to move backward and rise through the support rod 43, thereby moving the shaft disc 90 and the impeller bottom plate 91 to the bottom of the mounting frame 1, and lifting the two to the working position of the riveting machine 10. During this process, the support rod 43 supports the support seat 4 in the front and rear directions through the adjustment beam 6 and the end beam 20, and the support plate 31 supports the vertical plate 30, from The left and right sides support the supporting seat 4 and the assembly shaft 8 supported thereon. When the adjusting beam 6 moves backward to the limit position, the rear positioning groove on the rear side of the translation seat 3 is docked and engaged with the rear positioning block 25, and the front positioning groove on the front side of the translation seat 3 is docked and engaged with the front positioning block 62. The end beam 20, the translation seat 3 and the adjusting beam 6 are combined into one, which greatly enhances the stability of the translation seat 3. Then the adjusting motor 24 is stopped to keep the translation seat 3 and the shaft disc 90 and the impeller bottom plate 91 thereon fixed; then another pedal switch 16 is used to start the supporting motor 14, and the threaded barrel 13 is driven to rotate through the insertion rod 15. During the rotation process, the inner screw sleeve 11 drives the threaded barrel 13 to move through the thread, thereby adjusting the position of the support column 12;When determining the position of the support column 12, the operator must first use a clamp to clamp the rivet, feed the end of the rivet into the heating tube 70 on the control box 7, use a set of pedal switches 16 to control the heating tube 70 for heating, and after the rivet is heated to red and softened, use a clamp to insert the rivet into a set of rivet holes from the left side of the support column 12, rotate the assembly of the shaft disk 90 and the impeller bottom plate 91 to move the rivet to the position of the riveting machine 10, and then adjust the position of the support column 12 so that the support column 12 is against the nail cap of the rivet, and then maintain this position until the riveting process is completed; during riveting, the support column 12 is against the nail cap of the rivet The cap is supported, and the riveting machine 10 is started to press the end of the rivet into shape. Then the operator uses a clamp to take a new rivet from the tool box 17, heats the rivet, and inserts the rivet into the rivet hole adjacent to the riveted rivet. The impeller bottom plate 91 is manually rotated to move the new rivet to the riveting position. During this process, the universal ball 51 can reduce the friction caused by the clamp 5, so that the combination of the shaft disc 90 and the impeller bottom plate 91 can rotate smoothly. The continuous riveting process is carried out according to the above method. After the process is completed, the support seat 4 is controlled to move forward and fall, the assembly shaft 8 is pulled out, and the riveted shaft disc 90 and the impeller bottom plate 91 are removed. ;
