The second commutator is rotatably mounted on the fixed base via a fixed plate. The angle grinding discs are connected to the lower part of the second commutator via a coupling. The two angle grinding discs are driven to rotate by a pulley drive assembly and are driven to deflect synchronously along the X-axis direction by a connecting rod drive assembly.

[0009] Furthermore, the roller assembly has two rollers, which are respectively disposed on both sides of the traveling bracket. The roller assembly includes a connecting plate and two pairs of rollers. The two pairs of rollers are respectively rolled on the top and bottom surfaces of the guide rail beam on the same side.

[0016] The advantages of this invention are as follows: When the welding chamfering machine grinds the weld seam on the table, according to the grinding requirements, the grinding disc is driven to deflect along the X-axis by the connecting rod drive assembly, so that the grinding disc forms a certain angle with the table. The support moves downward, causing the grinding disc to press against the table. The grinding disc is driven to rotate by the pulley drive assembly. The traveling bracket is driven to move by the X-axis drive assembly, and moves the grinding disc along the weld seam to achieve weld grinding. When the grinding disc becomes thinner during the grinding process, the grinding head mechanism moves downward under the action of gravity, so that the grinding disc always maintains a certain working pressure with the table, thereby achieving effective grinding. When the grinding disc needs to be replaced, the Z-axis drive assembly drives the support to move upward, so that the grinding disc is away from the table for replacement. This realizes automated grinding of the weld seam on the table and improves grinding efficiency. Attached Figure Description

The connecting plate 303 is disposed on the side of the guide rail beam 301 away from the traveling bracket 302. The two ends of the rollers 304 are respectively connected to the traveling bracket 302 and the connecting plate 303. The two pairs of rollers of the roller assembly not only realize the movable connection between the traveling bracket 302 and the guide rail beam 301, but also limit the traveling bracket 302 in the Z-axis and Y-axis directions.

[0030] The X-axis drive assembly includes two gear and rack sets and an X-axis drive component 305. The two gear and rack sets are respectively arranged on both sides of the travel bracket 302. The rack 306 of the gear and rack sets is fixedly installed on the guide rail beam 301 on the same side, close to the travel bracket 302. The gear 307 of the same gear and rack set is arranged above the rack 306 and meshes with the rack 306. The racks 306 of the two gear and rack sets are mounted on the travel bracket 302 through the travel spindle 307. The central axis of the travel spindle 307 is horizontally mounted on the travel bracket 302. The gears 307 of the two gear and rack sets are rotatably mounted at both ends of the travel spindle 307.

[0031] The angle grinding head mechanism 4 includes a support 401, a fixed base 402, and two angle grinding discs 403 with parallel central axes.

The Z-axis drive component is mounted on the traveling bracket, and the Z-axis drive component 406 is a cylinder. The telescopic end of the Z-axis drive component 406 is connected to the support 401.

[0032] A pair of caster assemblies 418 are mounted on each side of the support 401 along the X-axis. The two caster assemblies 418 on the same side are located on both sides of the angle grinding plate 403. Each caster assembly 418 includes a caster 4181, a caster mounting base 4182, a guide sleeve 4183, a compression spring 4184, and a guide block 4185. The guide sleeve 4183 is vertically fixed on the support 401 via the central axis of the mounting plate 4186. The caster 4181 is located on the support 401. Below, and rotatably mounted on the bottom of the caster mounting base 4182, the top of the caster mounting base 4182 has a guide shaft 4187, the guide shaft 4187 is movably sleeved inside the guide shaft sleeve 4183, the guide pressure block 4185 is sleeved inside the guide shaft sleeve 4182 and located above the guide shaft 4187, and the compression spring 4184 is set inside the guide shaft sleeve 4183, with both ends of the compression spring 4184 connected to the guide shaft 4187 and the guide pressure block 4185 respectively. With the caster assembly 418 in place, when the angle grinding disc is grinding, the casters of the caster assembly press against the table, effectively supporting the support and keeping the contact pressure between the angle grinding disc and the table basically constant. As the angle grinding disc gradually thins, the angle grinding head mechanism moves downward under the action of gravity, ensuring that the angle grinding disc always maintains a certain working pressure with the table.

[0033] The fixed base 402 is rotatably mounted on the support 401 via a hinge pin 407. The central axis of the hinge pin 407 is rotatably mounted on the support 401 horizontally.

The two angle grinding discs 403 are respectively disposed on both sides of the hinge pin 407 and are rotatably mounted on the fixed base 402 via a second commutator 408. The second commutator 408 is rotatably mounted on the fixed base 402 via a fixing plate 409. The fixed plate 409 is rotatably mounted on the fixed base 402 via bearings. The central axis of the fixed plate 409 is parallel to the Y-axis. The second commutator is fixedly mounted on the fixed base 402.

The two ends of the coupling 410 are drivenly connected to the second commutator 408 and the angle grinding plate 403, respectively.

[0034] Two angle grinding discs 403 are driven to rotate by a pulley drive assembly and to deflect synchronously along the X-axis by a linkage drive assembly. The pulley drive assembly includes a rotary drive component 411 and a V-belt 412. The rotary drive component 411 is a motor and is fixedly mounted on the top of the fixed base 402. A first pulley 413 is mounted on the output end of the rotary drive component 411. Second pulleys 414 are driven and mounted on the side of the two second commutators 408 away from the fixed plate 409. The V-belt 412 is wound around the outside of the first pulley 413 and the two second pulleys 414 to form a triangle. The transmission structure includes a pulley drive assembly that enables the synchronous rotation of the two angle grinding discs. Furthermore, the pulley drive assembly also includes a tension roller 405, which is movably mounted on a fixed base 402. The fixed base 402 has a second oblong hole for horizontal movement of the tension roller 405. The tension roller 405 is movably positioned within the second oblong hole and is fixedly connected to the fixed base by bolts. The tension roller 405 is positioned outside the V-belt 412, which is wound around it. The tension of the V-belt 412 can be adjusted by changing the position of the tension roller 405. The linkage drive assembly includes a linkage 416 and two angle drive components 417 corresponding one-to-one with the fixed plate 409.

The linkage 416 is located above the hinge pin 407, and both ends of the linkage 416 are hinged to the top of the two fixed plates 409 respectively. The linkage drive assembly enables synchronous adjustment of the tilt angle of the two angle grinding plates, so that the central axes of the two angle grinding plates always remain parallel.

[0035] Working principle: When grinding the weld seam of the table plate 1, according to the grinding requirements, the angle grinding disc 403 is driven to deflect along the X-axis by the connecting rod drive assembly, so that the angle grinding disc 403 forms a certain angle with the table plate 1. The support 401 moves downward, causing the angle grinding disc 403 to press on the table plate 1. The angle grinding disc 403 is driven to rotate by the pulley drive assembly. The traveling bracket 302 is driven to move by the X-axis drive assembly, and moves the angle grinding disc 403 along the weld seam to achieve weld seam grinding. When the angle grinding disc 403 becomes thinner during the grinding process, the angle grinding head mechanism moves downward under the action of gravity, so that the angle grinding disc 403 always maintains a certain working pressure with the table plate 1, thereby achieving effective grinding. When it is necessary to replace the angle grinding disc 403, the Z-axis drive assembly drives the support 401 upward, so that the angle grinding disc 403 moves away from the table plate 1 for replacement.
