Abstract

The invention relates to the technical field of machine tools, in particular to a viaduct type portal machine tool high in rigidity, strength and stability. The machine tool structurally comprises a base, a first bridge base, a second bridge base, a first linear rail, a second linear rail and a Y-axis feeding system, wherein the first bridge base and the second bridge base are arranged on the twosides of the base respectively, the first linear rail is arranged on the first bridge base, the second linear rail is arranged on the second bridge base, and the two ends of the Y-axis feeding systemare connected with the first linear rail and the second linear rail slidingly respectively. The Y-axis feeding system comprises a lead screw base, a first shoulder base, a second shoulder base, a leadscrew and a motor, wherein the first shoulder base and the second shoulder base are connected to the two sides of the lead screw base respectively, the lead screw is arranged on the lead screw base,and the motor is arranged at the rear end of the lead screw base and in driving connection with the lead screw. The first shoulder base is connected with the first linear rail slidingly. The second shoulder base is connected with the second linear rail slidingly. The viaduct type portal machine tool has the advantages of being low in cost and high in running precision. The strength, rigidity and stability of the base, the Y-axis feeding system and the whole machine can be improved, and high-speed machining can be ensured.

Example Embodiment

[0032] The present invention will be described in detail below in conjunction with specific embodiments and drawings.

[0033] A viaduct type gantry machining machine tool with good rigidity and stability in this embodiment, such as figure 1 As shown, it includes a base 1, a first bridge base 2 and a second bridge base 3 respectively disposed on both sides of the base 1, a first linear rail 4 disposed on the first bridge base 2, and a second bridge base 3 The Y-axis feed system 6 slidably connected to the first line rail 4 and the second line rail 5 on both ends of the second linear rail 5; wherein, the Y-axis feed system 6 includes a screw seat 61, which is respectively connected to the screw rod The first shoulder seat 62 and the second shoulder seat 63 on both sides of the seat 61, the threaded rod 64 arranged on the threaded rod seat 61, the motor 65 arranged at the rear end of the threaded rod seat 61 and drivingly connected with the threaded rod 64; A shoulder 62 is slidably connected to the first wire rail 4, and the second shoulder 63 is slidably connected to the second wire rail 5. Compared with the prior art, the Y-axis only uses one set of feed system, thereby reducing costs, and avoiding the use of Y-axis dual-servo synchronous control technology that is difficult to overcome, and can avoid the problem of torsion of the beam, and has the accuracy of the whole machine. High advantages. And it can improve the strength, rigidity and stability of the base 1, the Y-axis feed system 6 and the whole machine, and can ensure high-speed processing.

[0034] In this embodiment, the screw seat 61, the first shoulder seat 62, and the second shoulder seat 63 are integrally formed, which can further improve the strength, rigidity and stability of the Y-axis feeding system 6.

[0035] In this embodiment, the screw seat 61 is provided with an inner cavity 601, and the screw 64 is disposed in the inner cavity 601, thereby facilitating processing.

[0036] In this embodiment, the first shoulder 62 is slidably connected to the first linear rail 4 via the first slider 7 and the second slider 8, thereby facilitating the feeding and processing of the screw 64.

[0037] In this embodiment, the second shoulder 63 is slidably connected to the second linear rail 5 through the third slider 9 and the fourth slider 10, thereby facilitating the feeding and processing of the screw 64.

[0038] In this embodiment, both the first bridge base 2 and the second bridge base 3 are provided with a through hole 11, which can reduce the mass of the first bridge base 2 and the second bridge base 3, thereby improving the stability of the base 1 .

[0039] In this embodiment, the through hole 11 is configured as a triangular through hole 11, and the triangular through hole 11 can ensure the strength of the first bridge seat 2 and the second bridge seat 3.

[0040] In this embodiment, both the first bridge base 2 and the second bridge base 3 are provided with two triangular through holes 11, which can reduce the mass of the first bridge base 2 and the second bridge base 3, thereby improving the stability of the base 1. It can ensure the strength of the first bridge seat 2 and the second bridge seat 3.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those of ordinary skill in the art should understand The technical solution of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solution of the present invention.
