Technical Field

[0002] As an advanced heavy-duty metal cutting equipment, CNC heavy-duty gantry mobile boring and milling machine is widely used in key industries such as energy, transportation, and shipbuilding. This equipment is known for its powerful processing capabilities and high precision, and can handle various complex and large workpieces. In order to adapt to the processing needs of parts of different heights and ensure good process system rigidity, the gantry mobile boring and milling machine is usually equipped with a crossbeam that can move vertically on the gantry frame.

[0003] The gantry frame is the core structure of the entire equipment, usually composed of columns arranged on the left and right sides and a crossbeam in the middle. This structural design not only provides strong support, but also ensures the stability of the equipment during operation. In order to achieve high-precision processing, the current national standard for inspection conditions of gantry milling machines has put forward strict requirements on the movement accuracy of the crossbeam, including the verticality of the crossbeam in two planes and the angular accuracy of the crossbeam during the operation of the gantry frame.

[0004] In order to meet these high-precision requirements, the coplanarity between the front guide surfaces of the columns on both sides must be guaranteed in advance during the assembly process, which means that the guide surfaces of the columns on both sides must be on the same plane to ensure that the beam will not tilt or deflect during movement. This precise assembly not only helps to improve processing accuracy, but also extends the service life of the equipment and reduces maintenance costs. Summary of the invention

The left wire pulling clamp is designed to be clamped on the outer wall of the left column 3 of the gantry frame. Its function is to fix one end of the steel wire 113 to ensure that the steel wire 113 remains stable and taut during the measurement process. The right wire pulling clamp is clamped on the outer wall of the right column 4 of the gantry frame. It corresponds to the left wire pulling clamp and is responsible for fixing the other end of the steel wire 113 to ensure that the steel wire is straightened between the two columns. The steel wire 113 is a key component connecting the left wire pulling clamp and the right wire pulling clamp. The steel wire 113 has sufficient strength and rigidity to ensure that no obvious deformation or relaxation occurs in the tensioned state; A steel wire 113 is provided between the left wire pulling pliers and the right wire pulling pliers, and weights 11 are provided at both ends of the steel wire 113.

The smooth pressure block 13 is located between the adjustable wrench 12 and the right column 4 of the gantry frame. When the adjustable wrench 12 rotates, the adjusting bolt pushes the smooth pressure block 13 to fit tightly against the right column 4 of the gantry frame, thereby increasing friction and ensuring that the right wire pulling pliers are firmly fixed to the outer wall of the right column 4 of the gantry frame.

Spring washers 111 are provided on both sides of the compression spring 110 to limit the compression spring 110 to prevent it from shifting during work. Two through holes are provided on the opposite side of the movable wrench 12 on the right clip 114, which are a light hole and a threaded hole respectively. An alignment rod 15 is provided in the light hole to ensure the alignment of the left and right wire pulling pliers during installation.

A back cap 18 is provided at the lower end of the pulley 19 to lock the position of the pulley 19 to prevent it from loosening during work. The pulley 19 is a groove pulley, and a steel wire 113 is embedded in its groove. Both ends of the steel wire 113 are connected to weights 11. The steel wire 113 is wound in the groove pulley, and the steel wire 113 is tightened by the weight of the weight 11 to ensure the accuracy of the measurement.
