Abstract
Description
Technical Field
[0001] This utility model relates to the field of crossbeam technology for gantry machining centers, and in particular to a stable structure for the crossbeam of a gantry five-axis machining center. Background Technology
[0002] A gantry-type five-axis machining center is a high-end CNC machine tool that integrates the high rigidity of a gantry structure with the high precision and flexibility of five-axis linkage. It is widely used in aerospace, automotive mold making, and energy equipment industries. In existing gantry-type machining centers, the crossbeam is one of the main components. As the basic component of the machine tool's Y-axis, the crossbeam not only bears the weight of the saddle and ram components but also the cutting forces during machining. Therefore, the rigidity and strength of the crossbeam directly affect the overall machining performance and accuracy of the machine tool.
[0003] In existing technologies, the fixed crossbeam is bolted to the top of the columns on both sides of the gantry-type five-axis machining center, and the Y-axis slide of the machining center is installed on the crossbeam. However, the structure of this type of crossbeam is relatively simple, and its stability after installation at the columns is limited. During the frequent processing and force application of the machining center, the stability of the crossbeam at the columns cannot be guaranteed. Therefore, we propose a crossbeam stabilization structure for gantry-type five-axis machining centers. Utility Model Content
[0004] The main objective of this invention is to provide a stable beam structure for a gantry-type five-axis machining center. By installing a stabilizing support mechanism on the beam body of the gantry-type five-axis machining center, the convex plate of the stabilizing support mechanism is fitted into the side mounting groove of the beam with a boss and locked with bolts on the side extension plate, forming a dual fixation of lateral limiting and vertical bearing. This prevents the beam body from shifting laterally along the column when under stress. Simultaneously, the U-shaped support, combined with the welded combination of the inclined connecting plate and the vertical frame seat, disperses the weight of the sliding saddle and cutting force borne by the beam body to the vertical frame seat, significantly reducing local stress concentration in the beam and minimizing the risk of bending deformation. Furthermore, the bottom of the vertical frame seat is connected to a T-shaped box pre-embedded in the ground via a base pressure plate, forming rigid support on both sides of the beam body. This effectively counteracts the overturning moment of the beam during machining, preventing the beam from tilting upwards at both ends or sagging downwards in the middle due to frequent stress application. This fundamentally ensures the positional stability of the beam during long-term machining and effectively solves the problems in the prior art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A gantry-type five-axis machining center crossbeam stabilization structure includes a crossbeam body with side mounting slots on both sides. It also includes a stabilizing mechanism comprising a side extension plate, a convex plate, a U-shaped support, an inclined connecting plate, a vertical frame seat, a base pressure plate, and a T-shaped fitting box. A side extension plate is integrally formed on the outer side of the crossbeam body above the side mounting slots, and a convex plate is bolted to the bottom of the side extension plate. The convex plate is inserted into the upper cavity of the side mounting slot, and a vertical frame seat is welded to the lower plate of the convex plate via a U-shaped support. An inclined connecting plate is obliquely welded between the vertical wall of the vertical frame seat and the U-shaped support. A base pressure plate is integrally formed on the base plate of the vertical frame seat, and the base pressure plate is bolted to the top of the T-shaped fitting box. A pouring port is provided between the base pressure plate and the T-shaped fitting box.
[0007] Furthermore, the edge of the convex plate has a protrusion, and the protrusion is inserted into the upper cavity of the side mounting groove.
[0008] By adopting the above technical solution, the convex plate can be fixed in the upper cavity of the side mounting groove to provide support.
[0009] Furthermore, the seat of the vertical frame is a hollow seat, and an inner support rib is integrally formed in the inner cavity of the vertical frame seat;
[0010] By adopting the above technical solution, the hollow seat of the vertical frame can provide stable support for the U-shaped support and the convex plate in conjunction with the internal support bars.
[0011] Furthermore, the lower plate surface of the base plate away from the pouring port is provided with a T-shaped groove for mounting the T-shaped guide strip, and the T-shaped guide strip is integrally formed on the top wall of the T-shaped box.
[0012] By adopting the above technical solution, the base plate can be guided and positioned at the T-shaped guide strip at the top of the T-shaped box using the T-shaped groove.
[0013] Furthermore, the T-shaped box has a hollow body, and the T-shaped box is vertically connected to the pouring port of the base plate;
[0014] By adopting the above technical solution, concrete can be poured from the pouring port of the base plate along the pouring port of the T-shaped box into the further empty box for solidification and counterweight.
[0015] Furthermore, mounting holes for screw bolts are provided between the convex plate and the side extension plate, and mounting holes for screw bolts are provided between the T-shaped fitting box and the base plate.
[0016] By adopting the above technical solution, the mounting holes of the convex plate and the side extension plate can be locked by screwing bolts, and the mounting holes of the T-shaped box and the base plate can also be locked by screwing bolts.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] This utility model sets a stabilizing support mechanism on the crossbeam body of a gantry-type five-axis machining center. The convex plate of the stabilizing support mechanism is clamped to the side mounting groove of the crossbeam with a boss and locked with the side extension plate bolts to form a double fixation of lateral limiting and vertical bearing, which prevents the crossbeam body from shifting laterally along the column when under force. At the same time, the U-shaped support, together with the welded combination of the inclined connecting plate and the vertical frame seat, disperses and transfers the saddle weight and cutting force borne by the crossbeam body to the vertical frame seat, which greatly reduces the local stress concentration of the crossbeam and reduces the risk of bending deformation.
[0019] Furthermore, the bottom of the vertical frame base is connected to the T-shaped box pre-embedded in the ground through the base pressure plate, forming rigid support on both sides of the beam, effectively offsetting the overturning moment of the beam during processing, and preventing the beam from tilting upwards at both ends or drooping downwards in the middle due to frequent force application, thus fundamentally ensuring the positional stability of the beam during long-term processing.

The side extension plate 4 is integrally formed on the outer side of the crossbeam body 1 above the side mounting slots 2, and a convex support plate is bolted to the bottom of the side extension plate 4. Plate 5, the convex plate 5 is inserted into the upper cavity of the side mounting groove 2, and a vertical frame seat 8 is welded to the lower plate of the convex plate 5 through a U-shaped support 6. An inclined connecting plate 7 is welded between the vertical wall of the vertical frame seat 8 and the U-shaped support 6. A base pressure plate 9 is integrally formed at the base plate of the vertical frame seat 8. The base pressure plate 9 is locked to the top of the box body of the T-shaped box 12 by bolts, and a pouring port 13 is opened through between the base pressure plate 9 and the T-shaped box 12.
[0026] The convex plate 5 has protruding bosses on its plate edge, and the bosses are inserted into the upper cavity of the side mounting groove 2.
[0027] By adopting the above technical solution, the protruding plate 5 can be fitted into the upper cavity of the side mounting groove 2 to provide support.
[0028] The vertical frame seat 8 has a hollow seat body, and an inner support rib 14 is integrally formed in the inner cavity of the vertical frame seat 8.
[0029] By adopting the above technical solution, the hollow seat of the vertical frame seat 8 can work with the inner support rib 14 to stably provide support for the U-shaped support 6 and the convex plate 5.
[0030] The base plate 9 has a T-shaped groove 10 on its lower surface away from the pouring port 13 for mounting the T-shaped guide strip 11, and the T-shaped guide strip 11 is integrally formed on the top wall of the T-shaped box 12.
[0031] By adopting the above technical solution, the base plate 9 can be guided and positioned at the T-shaped guide strip 11 at the top of the T-shaped box 12 using the T-shaped groove 10.
[0032] The T-shaped box 12 has a hollow box body, and the T-shaped box 12 is vertically connected to the pouring port 13 of the base plate 9.
[0033] By adopting the above technical solution, concrete can be poured from the pouring port 13 of the base plate 9 into the hollow box of the T-shaped distribution box 12 for solidification and counterweighting.
[0034] Among them, mounting holes for screw bolts are provided between the convex plate 5 and the side extension plate 4, and mounting holes for screw bolts are provided between the T-shaped box 12 and the plate body of the base plate 9.
[0035] By adopting the above technical solution, the mounting holes of the convex plate 5 and the side extension plate 4 can be locked by screwing bolts, and the mounting holes of the T-shaped box 12 and the base plate 9 can be locked by screwing bolts.
[0036] It should be noted that this utility model is a stabilizing structure for the crossbeam of a gantry-type five-axis machining center.

After the crossbeam body 1 is installed at the column of the machining center using bolts, the convex plates 5 of the stabilizing support mechanism 3 are inserted on both sides of the crossbeam body 1. Bolts are then screwed into the convex plates 5 from the side extension plates 4 for locking, allowing the U-shaped support 6 and the vertical frame seat 8 to press against the crossbeam body 1 and the outer side of the column. A foundation pit is then dug in the ground below the base pressure plate 9, and the T-shaped fitting box 12 is inserted into the T-shaped groove 10 of the base pressure plate 9 using T-shaped guide strips 11.

Then, concrete is poured into the box from the pouring port 13 of the base plate 9 and the T-shaped box 12. After the concrete is vibrated evenly with a vibration device, wait for the concrete to solidify and counterweight in the T-shaped box 12. When the crossbeam body 1 of the gantry five-axis machining center is under force, the stabilizing support mechanism 3 on both sides provides ground support to ensure the stability of the crossbeam body 1.
[0037] After the bolts at the side extension plate 4 are unscrewed, the bolts at the base pressure plate 9 are unscrewed. At this time, the convex plate 5 can be pulled out laterally from the side mounting groove 2, and the vertical frame seat 8 is continuously pulled, so that the T-shaped guide strip 11 of the base pressure plate 9 is pulled out from the T-shaped box 12. At this time, the support frame composed of the convex plate 5, U-shaped support 6, vertical frame seat 8 and base pressure plate 9 can be removed.
