[0020] As Figure 1 shown: A crossbeam riveting clamp table includes a base 1, a slide rail 2, a movable fixture 3, a limit baffle 4, a locking device 5, and a horizontal platform 6; on the top surface of the base 1, two groups of slide rails 2 are symmetrically arranged, and each group of slide rails 2 includes two or more parallel linear tracks. On each group of slide rails 2, a movable fixture 3 is symmetrically slidably arranged. On the top surface of the base 1, between the two groups of slide rails 2, limit baffles 4 are symmetrically fixed. The limit baffles 4 are in movable contact with the movable fixture 3. On both sides of the base 1, two locking devices 5 are symmetrically arranged. The push rod 502 of the locking device 5 is in movable contact with the movable fixture 3. The movable fixture 3 can move along the slide rail 2 between the limit baffle 4 and the locking device 5. On the top surface of the base 1, between the two movable fixtures 3, a horizontal platform 6 is movably arranged up and down. On the movable fixture 3 and the horizontal platform 6, a plurality of positioning holes 7 are opened. The positioning holes 7 correspond to the holes opened on the crossbeam and the connecting parts at both ends, and bolts, positioning pins or fixtures can be inserted into the positioning holes 7 for temporary positioning and fixing.

[0021] As Figure 2As shown in the figure: The movable fixture 3 includes a cross plate 301, a vertical plate 302 and a reinforcing rib 303. The bottom surface of the cross plate 301 is slidably connected to the two linear tracks of each group of slide rails 2 through sliders. On the top surface of the cross plate 301, on one side edge perpendicular to the linear track, a vertical plate 302 is vertically fixed. A plurality of positioning holes 7 are provided on the vertical plate 302. The vertical plate 302 is used to temporarily fix the connecting pieces at both ends of the cross beam. Bolts, positioning pins or fixtures can be used to pre-fix the connecting pieces on the vertical plate 302. A reinforcing rib 303 is fixedly provided between the vertical plate 302 and the cross plate 301. The reinforcing rib 303 is used to prevent the vertical plate 302 from deforming and ensure the assembly accuracy.

[0022] As Figure 3 , Figure 4 shown in the figure: The locking device 5 includes a sliding sleeve 501, a push rod 502, a driving rod 503, a connecting rod 504 and a handle 505. A sliding sleeve 501 parallel to the slide rail 2 is fixedly provided on the top surface of the base 1. A push rod 502 is movably sleeved in the sliding sleeve 501. A top cap 507 is screwed at one end of the push rod 502 in contact with the movable fixture 3. The push rod 502 is in movable contact with the movable fixture 3 through the top cap 507. The top cap 507 is used to adjust the length of the push rod 502. By screwing the top cap 507 in or out as needed, the push rod 502 can just press the movable fixture 3 tightly. The other end of the push rod 502 is hinged to one end of a "C"-shaped connecting rod 504. A transverse groove 506 is provided at the top of the sliding sleeve 501. The connecting rod 504 slides in the transverse groove 506. The tail of the sliding sleeve 501 is hinged to one end of the driving rod 503. The other end of the driving rod 503 is hinged to the other end of the connecting rod 504. A handle 505 is integrally formed perpendicular to the driving rod 503 at the hinge position of the driving rod 503 and the sliding sleeve 501. When locking is required: Around the hinge point of the driving rod 503 and the sliding sleeve 501, push the handle 505 upward. The handle 505 drives the driving rod 503 to rotate around the hinge point at the tail end of the sliding sleeve 501, driving the connecting rod 504 at the other end to slide forward along the transverse groove 506. The push rod 502 hinged to the other end of the connecting rod 504 moves forward, pushing the movable fixture 3 in front to move towards the middle until the movable fixture 3 abuts against the limit baffle 4. At this time, the hinge point of the driving rod 503 and the connecting rod 504 is located above the axis of the push rod 502. Continue to push the handle 505. At this time, the push rod 502 cannot continue to move forward. The "C"-shaped connecting rod 504 is squeezed and gradually generates a certain elastic deformation, so that the hinge point of the driving rod 503 and the connecting rod 504 continues to move downward until it exceeds the axis of the push rod 502 and is placed below the axis. When the hinge point of the driving rod 503 and the connecting rod 504 is stuck on the inner wall of the sliding sleeve 501, the force generated by the elastic deformation of the connecting rod 504 being squeezed locks the driving rod 503 in this position. The push rod 502 presses the movable fixture 3 tightly against the limit baffle 4, playing a locking role. When release is required, pull the handle 505 in the reverse direction, and the push rod 502 can be retracted to release the movable fixture 3.

[0023] As Figure 5 shown: The horizontal platform 6 includes a bearing plate 601, a height-adjusting screw rod 602 and a height-adjusting nut 603; two through holes are provided on the base 1 between the two movable jigs 3, and the height-adjusting screw rods 602 are respectively inserted into the two through holes. The height-adjusting screw rod 602 is externally threaded with a height-adjusting nut 603. The height-adjusting nut 603 is in movable contact with the top surface of the base 1. The tops of the two height-adjusting screw rods 602 are hinged to the bottom surface of the bearing plate 601. A plurality of positioning holes 7 are provided on the bearing plate 601; the bearing plate 601 is used to temporarily fix the positioning cross beam. The two height-adjusting screw rods 602 hinged to the bottom of the bearing plate 601 can adjust the height by rotating the externally screwed height-adjusting nuts 603 on the outside, so that the cross beam is placed at a predetermined position and angle.

[0024] For convenient operation, an ejection device 8 is further provided. The ejection device 8 includes a positioning sleeve 801 and an ejection spring 802. Two positioning sleeves 801 are fixedly provided on one side of the limit baffle 4 in contact with the movable jig 3. An ejection spring 802 is fixedly sleeved in the positioning sleeve 801. The other end of the ejection spring 802 is in movable contact with the movable jig 3. After the locking device 5 is released, the ejection spring 802 pushes the movable jig 3 to both sides to separate the movable jig 3 from the cross beam after riveting, making the operation more convenient and improving work efficiency.

[0025] Working principle: When riveting is required, first place the cross beam on the horizontal platform 6, and fix it through the hole positions on the cross beam and the positioning holes 7. The connecting pieces to be riveted at both ends of the cross beam are temporarily fixed on the movable jig 3 through the positioning holes 7. After the cross beam and the connecting pieces are both fixed, the movable jig 3 is clamped towards the middle by the push rod 502 of the locking device 5 and locked after contacting the limit baffle 4. At this time, the cross beam and the connecting pieces at both ends are placed at the preset positions, and then riveting is fixed by a pneumatic riveting machine. After riveting is completed, remove the temporary fixing bolts in the positioning holes 7 and retract the push rod 502 of the locking device 5 in the reverse direction, and the riveted cross beam can be removed; only one disassembly is required for the entire riveting process, the operation is convenient, the efficiency is high, and the connecting pieces on both sides are riveted at the same time, with small errors and high alignment positioning accuracy.
