Description

Beam with high structural strength

Technical Field

The application relates to the technical field of machine tools, in particular to a cross beam with high structural strength.

Background

The beam is an important component of the gantry machine tool, and is required to have high rigidity and high strength as a base part of the machine tool Y-axis because it is required to carry not only the weight of a cutting-related tool but also the cutting force of the machine tool machining. However, on some gantry machine tools with large processing strokes, the structural strength of the cross beam is often insufficient due to large span, and the existing cross beam is provided with a reinforcing structure, but is uniformly dispersed in the cross beam, so that the whole cross beam is reinforced, the unnecessary cross beam weight is increased to cause material redundancy, the manufacturing cost is increased, and the dynamic response performance of the cross beam is reduced.

Disclosure of Invention

The objectives and other advantages of the application may be realized and attained by the structure particularly pointed out in the written description and drawings hereof.

The purpose of this application is overcome above-mentioned not enough, provides a crossbeam with high structural strength, has structural strength height, dispersed stress, non-deformable, stability is good, low in production cost's advantage.

In order to achieve the above purpose, the technical solution of the present application is: a beam with high structural strength comprises a beam body and a reinforcing structure arranged in the beam body. The reinforcing structure comprises an arched reinforcing rib plate and a supporting rib plate, wherein the reinforcing rib plate is transversely arranged in the beam body, the supporting rib plate comprises a first supporting rib plate and a second supporting rib plate which are obliquely arranged, the first supporting rib plate is connected with the reinforcing rib plate and an upper top plate of the beam, and the second supporting rib plate is connected with the reinforcing rib plate and a lower top plate of the beam.

According to the method, the arch reinforcing rib plates are arranged in the cross beam, the arch structure is utilized to transfer the vertical load born by the cross beam to the supporting legs on the two sides, and a reaction force is generated to act inside the arch, so that the stability of the arch structure is enhanced, the cross beam damage caused by stress concentration is avoided, the bending moment generated by the arch structure is small, and the bearing strength of the long cross beam can be ensured while material redundancy is not generated; and the inclined support rib plates are arranged, so that the arched reinforcing rib plates are secondarily reinforced according to the stress characteristics of the arch, and the overall structural strength of the cross beam is improved.

In some embodiments, the reinforcing plate is provided with at least two rounded rectangular holes. The reinforcing rib plate locally reinforces the front and rear side walls of the cross beam, and rectangular holes are formed in the reinforcing rib plate, so that the self weight of the cross beam can be effectively reduced while the reinforcing bearing performance is ensured, and the overall structural stability and dynamic corresponding performance of the machine tool are improved.

In some embodiments, the support gusset is an annular cross-sectional structure. The annular section structure strengthens the circumferential supporting strength inside the cross beam, reduces the increase of unnecessary materials and reduces the manufacturing cost.

In some embodiments, the first and second brace webs are symmetrically distributed about a highest point of the stiffener web. The symmetrical distribution taking the highest point of the reinforcing rib plate as a reference is beneficial to carrying out local symmetrical reinforcement on the middle part without supporting legs at the bottom, and carrying out key reinforcement on the middle position of the beam according to the beam structure and the stress characteristics, and the reinforcement amount gradually decreases towards two sides from the middle point position, so that the key reinforcement of the beam is realized, and the material redundancy is avoided.

In some embodiments, the upper side of the first gusset is a greater horizontal distance from the highest point of the gusset than the lower side of the first gusset. The first support rib plates incline to the two sides of the highest point of the reinforcing rib plates, so that the pressure received by the upper part is dispersed to the middle arched reinforcing rib plates, the aggravation of deformation caused by the concentration of stress generated by overlarge local stress is avoided, and meanwhile, the structure of the middle reinforcing rib plates can be stabilized like a cable-stayed bridge structure in a bridge.

In some embodiments, the upper side of the second gusset is at a horizontal distance from the highest point of the gusset that is less than the horizontal distance from the lower side of the second gusset to the highest point of the gusset. The second support rib plate inclines to the highest point of the reinforcing rib plate, so that acting force born by the reinforcing rib plate can be dispersed to the lower end, and meanwhile, the second support rib plate has the structural advantage of lifting the lower side, deformation caused by stress of the lower Fang Daogui is reduced, and the machining precision of a machine tool is improved effectively.

In some embodiments, the rear side of the beam body is a hollowed-out surface corresponding to the reinforcing structure. And the corresponding hollowed back side is designed according to the shape of the reinforcing structure, so that the heat dissipation inside the cross beam is increased on the premise of ensuring the supporting strength.

In some embodiments, the front side of the beam body is provided with a stress rail, and one side of the rear side of the beam body is inclined forward, so that the side of the beam body is trapezoid. According to the stress characteristics and the reinforcing structure of the cross beam, the trapezoidal cross beam is designed to balance the gravity center on the gravity center line similar to the triangle when in load, so that the bearing capacity and the overall rigidity of the cross beam are improved.

Through adopting foretell technical scheme, the beneficial effect of this application is:

through setting up the supporting rib plate of arch deep floor and slope, dispersion crossbeam load pressure, reinforcing beam structural strength, and then improve the stability of crossbeam, and deep floor and supporting rib plate mid portion set up the fretwork, form annular section structure, can effectively reduce the crossbeam weight under the condition that does not influence processability than the totally enclosed, promote lathe overall structure's stability, still be convenient for cast processing, effectively reduce manufacturing cost and stress concentration.
