The setting of the limit plate 52 can ensure that the second grinding wheel 54 will not be laterally offset during the grinding process, so as to adapt to longitudinal beams of different widths.

[0031] In order to facilitate the grinding of the web of the longitudinal beam without interfering with the normal feeding of the longitudinal beam, Figure 8As shown, the fixed side ventral surface grinding device 6 includes a first ventral surface grinding frame 60, a first lifting cylinder 61 is hingedly installed on the top of the first ventral surface grinding frame 60, a first swing lifting frame 62 is also installed on the first ventral surface grinding frame 60, one end of the first swing lifting frame 62 is hinged on the first ventral surface grinding frame 60, and a horizontally arranged third grinding motor 63 is installed on the other end of the first swing lifting frame 62, a third grinding wheel 64 is installed on the output shaft of the third grinding motor 63, a first connecting shaft 65 is also provided in the first swing lifting frame 62, and the piston rod of the first lifting cylinder 61 is connected to the first connecting shaft 65.

[0032] When the piston rod of the first lifting cylinder 61 is extended and retracted, the third grinding wheel 64 can be driven to perform vertical lifting and swinging through the first swing lifting frame 62, so that the moving reference side of the web of the longitudinal beam can be polished, and the grinding depth can be adaptively adjusted according to the lifting amplitude.

[0033] Furthermore, in order to facilitate adaptive grinding of the belly surfaces of different width types of stringers, e.g. Fig. 9 As shown, the floating flank grinding device 7 includes a second flank grinding frame 70, a second lifting cylinder 71 is hingedly installed on the top of the second flank grinding frame 70, a second swing lifting frame 72 is also installed on the second flank grinding frame 70, one end of the second swing lifting frame 72 is hinged on the second flank grinding frame 70, a horizontally arranged fourth grinding motor 73 is installed on the other end of the second swing lifting frame 72, a fourth grinding wheel 74 is installed on the output shaft of the fourth grinding motor 73, a second connecting shaft 75 is also provided in the second swing lifting frame 72, and the piston rod of the second lifting cylinder 71 is connected to the second connecting shaft 75.

[0035] An adjustment motor 76 and a fourth slide rail 77 are also provided on the base frame 1. A fifth slider 78 matching the fourth slide rail 77 is installed at the bottom of the second belly surface grinding frame 70. A second screw rod 79 is installed on the output shaft of the adjustment motor 76. A second nut 710 matching the second screw rod 79 is provided at the bottom of the second belly surface grinding frame 70. When the adjustment motor 76 is started, it can drive the overall floating side belly surface grinding device 7 to move away from or close to the fixed side belly surface grinding device 6, that is, to adjust the position of the fourth grinding wheel 74 in the width direction of the longitudinal beam, and realize all-round grinding of the longitudinal beam web through the third grinding wheel 64 and the fourth grinding wheel 74.

The diameter of a single wing surface grinding wheel of the first grinding wheel 43 or the second grinding wheel 54 is sufficient to pass through the longitudinal beam with the smallest cross section, and the sum of the diameters of the two wing surface grinding wheels is greater than the inner width of the longitudinal beam with the largest cross section, so that the longitudinal beam can be fed normally while the belly surface and wing surface of the longitudinal beam can be fully ground.

[0038] The longitudinal beam driving device 2 transports the beam to be polished, and the material pressing device 3 prevents the posture of the beam from changing too much during the transportation process. The spacing between the four grinding wheels is adjusted according to the width of the longitudinal beam, so that the left and right wing surfaces and the belly surface can be polished when the longitudinal beam passes. The circumferential surface and the top end surface of the above-mentioned grinding wheel can be made into a brush type.

[0039] The grinding device is used after the U-shaped beam is plasma cut. The operation process of grinding the longitudinal beam using the above-mentioned grinding device is as follows:

[0040] Before grinding, according to the width of the longitudinal beam, the adjustment motor 76 of the floating side and belly surface grinding device 7 drives the base to the appropriate position, the driving cylinders of the fixed side wing surface grinding device 4 and the floating side wing surface grinding device 5 are retracted, and the grinding wheel reaches the grinding position in advance; when the beam passes through the belly surface grinding device, the second driving cylinder 31 of the pressing device 3 extends to press the beam, the floating side wing surface grinding device 5 drives the limit plate 52 to the appropriate position, and the piston rod of the fourth driving cylinder 58 retracts to push the second adjustment plate 51 to the limit plate 52, so that the grinding wheel and the inner wing surface on the right side of the longitudinal beam have a suitable distance. The longitudinal beam is fed in, the grinding wheel rotates, and the belly and wing surface of the longitudinal beam are ground. After the grinding is completed, the driving cylinders at each grinding head position extend to make the grinding wheel separate from the grinding surface, and the longitudinal beam continues to be fed in.

[0041] The grinding device described in the present device can be installed on the longitudinal beam conveying line, and enter the bottom of the gantry 30 of the grinding device and the pressing device 3 from the length direction of the longitudinal beam. Further, in order to be applicable to various material conveying process devices, it is convenient to grab the longitudinal beam and other materials from the upper part of the gantry 30 and put them into the longitudinal beam driving device 2 for grinding operation, such as Figure 11-13As shown, the gantry 30 includes a first column 36 and a second column 37 which are vertically arranged, a movable cross frame 38 is installed between the first column 36 and the second column 37, and the second driving cylinder 31 is installed on the cross frame 38.

[0042] A guide rail 39 is installed at the bottom of the cross frame 38, and a guide sleeve 310 matching the guide rail 39 is installed at the top of the second column 37. The second column 37 and the guide sleeve 310 at the top are strong enough to support the entire cross frame 38. In order to achieve the lateral movement of the cross frame 38, a rack 311 is installed on the side of the cross frame 38, and a lateral movement motor 312 is installed on the second column 37. A gear 313 matching the rack 311 is provided on the output shaft of the lateral movement motor 312. When the lateral movement motor 312 is started, it can drive the cross frame 38 to move along the guide sleeve 310.

[0043] In order to realize the coordinated positioning of the cross frame 38 on the first column 36, a guide wheel 314 and a positioning hole 315 are further provided at the end of the cross frame 38 close to the first column 36. A guide groove 316 cooperating with the guide wheel 314 is provided on the first column 36. A locking cylinder 317 is also installed on the first column 36. The piston rod of the locking cylinder 317 can extend into the positioning hole 315, so as to realize the positioning installation of the cross frame 38 between the first column 36 and the second column 37. After the piston rod of the locking cylinder 317 is retracted and exits the positioning hole 315, as shown in FIG. Fig.14 As shown, the start of the transverse motor 312 can drive the cross frame 38 to move away from the first column 36, leaving necessary space for the longitudinal beam to enter and exit the top of the gantry 30, so that the conveying devices of different processes can vertically convey the longitudinal beam from the top of the grinding device.
