[0032] Embodiment 1
[0033] See also Figure 1 In one embodiment of the present application, a crossbeam structure 100 is provided. The crossbeam structure 100 is used in a five-axis vertical machining center.
[0034] See also Figures 1 to 3The beam structure 100 has a first direction X, a second direction Y and a third direction Z, the first direction X is perpendicular to the second direction Y, and the third direction Z is perpendicular to the first direction X and the second direction Y.
[0035] It is understandable that the above definitions are only for facilitating the understanding of the relative positional relationship of the various parts in the beam structure 100 and should not be construed as a limitation to the present application.
[0036] See also Figures 1 to 3 The crossbeam structure 100 includes a main body 110 and a plurality of first inner ribs 117 .
[0037] Among them, the main body 110 includes a first side panel 111, a second side panel 112, a third side panel 113, a fourth side panel 114, a fifth side panel 115 and a sixth side panel 116, the first side panel 111 and the second side panel 112 are arranged opposite to each other along the first direction X, the third side panel 113 and the fourth side panel 114 are arranged opposite to each other along the second direction Y, the fifth side panel 115 and the sixth side panel 116 are arranged opposite to each other along the third direction Z, and the first side panel 111, the second side panel 112, the third side panel 113, the fourth side panel 114, the fifth side panel 115 and the sixth side panel 116 are enclosed to form an inner cavity.
[0038] Multiple first inner ribs 117 are arranged in the inner cavity at intervals along the second direction Y, and the two ends of the first inner rib 117 along the first direction X are respectively connected to the first side plate 111 and the second side plate 112, and the two ends of the first inner rib 117 along the third direction Z are respectively connected to the fifth side plate 115 and the sixth side plate 116; the first inner rib 117 is provided with a circular weight-reducing hole 1171, and the weight-reducing hole 1171 extends along the first direction X.
[0039] The first inner rib plate 117 can improve the strength of the main body 110; the circular weight-reducing holes 1171 opened on the first inner rib plate 117 can not only reduce the overall weight of the crossbeam structure 100, but also make the gravity of the main body 110 reasonably decompose to the first side panel 111 and the second side panel 112, thereby avoiding the bending and deformation of the fifth side panel 115 and the sixth side panel 116.
[0040] In some embodiments, see Figure 3 , multiple first inner ribs 117 are evenly arranged along the second direction Y in the inner cavity.
[0041] In some embodiments, see Figure 3The crossbeam structure 100 also includes a plurality of second inner ribs 118, which are spaced apart in the inner cavity along the third direction Z, the second inner ribs 118 are passed through the first inner ribs 117, the two ends of the second inner ribs 118 along the first direction X are respectively connected to the first side plate 111 and the second side plate 112, and the two ends of the second inner ribs 118 along the third direction Z are respectively connected to the fifth side plate 115 and the sixth side plate 116.
[0042] The second inner rib 118 can further improve the strength of the body 110 .
[0043] In some embodiments, the second inner ribs 118 are evenly arranged along the third direction Z in the inner cavity.
[0044] In some embodiments, see Figure 1 and Figure 2 The crossbeam structure 100 further includes a first guide rail 120 and a second guide rail 121. The first guide rail 120 and the second guide rail 121 are respectively slidably matched with the first side plate 111. The first guide rail 120 and the second guide rail 121 both extend along the second direction Y.
[0045] The first guide rail 120 and the second guide rail 121 are respectively slidably matched with the first side plate 111 so that the body 110 can move along the second direction Y.
[0046] In some embodiments, a first slide seat 140 and a second slide seat 141 are respectively provided on the first side panel 111; the first slide seat 140 and the first guide rail 120 are slidably matched through a slider, so that the first guide rail 120 and the first side panel 111 can have relative movement; the second slide seat 141 and the second guide rail 121 are slidably matched through a slider, so that the second guide rail 121 and the first side panel 111 can have relative movement.
[0047] In some embodiments, the first side plate 111 has a stepped portion 1111 , and the first sliding seat 140 is disposed on the stepped portion 1111 .
[0048] The step portion 1111 makes the first slide 140 and the second slide 141 arranged in a step manner, so that there is a step difference between the first guide rail 120 and the second guide rail 121, so that during the movement of the machine tool, the center of gravity of the slide is close to the guide rail to increase the rigidity, which is beneficial to improving the stability of machine tool processing and the processing accuracy of parts.
[0049] In some embodiments, see Figure 3The second side panel 112 includes a weight-reducing inclined plate 1121 and a connecting plate 1122 connected to each other, the weight-reducing inclined plate 1121 is connected to the fifth side panel 115 at a side away from the connecting plate 1122, the connecting plate 1122 is perpendicular to the sixth side panel 116, and the connecting plate 1122 is connected to the sixth side panel 116 at one end away from the weight-reducing inclined plate 1121.
[0050] Since the weight-reducing inclined plate 1121 is arranged at an angle, the cross-sectional area of the main body 110 along the third direction Z can be effectively reduced, thereby reducing the weight of the main body 110 and improving the dynamic response characteristics of the beam structure 100 .
[0051] In some embodiments, see Figure 1 The crossbeam structure 100 further includes at least one third guide rail 122 slidably matched with the sixth side plate 116 , and the third guide rail 122 extends along the second direction Y, thereby enabling the body 110 to move along the second direction Y.
[0052] In some embodiments, the beam structure 100 further includes at least one third slide 142, which is disposed on the sixth side plate 116. The third slide 142 slidably cooperates with the third guide rail 122 via a slider, thereby enabling the body 110 to move along the second direction Y.
[0053] In some embodiments, the beam structure 100 includes two third guide rails 122, and two third slide seats 142 are provided at both ends of the sixth side plate 116 along the second direction Y, and the two third slide seats 142 on one end of the sixth side plate 116 along the second direction Y are respectively slidably matched with one of the third guide rails 122.
[0054] In some embodiments, the crossbeam structure 100 further includes two driving members 130 , and the two driving members 130 are respectively disposed on the third side plate 113 and the fourth side plate 114 .
[0055] Furthermore, the two driving members 130 are symmetrically arranged, and the driving members 130 correspond to the center of gravity of the main body 110, so that the driving force is at the center of gravity of the main body 110, avoiding the driving force from generating a subverting torque on the main body 110, reducing the vibration of the five-axis vertical machining center under large acceleration, and thereby improving the machining accuracy of the five-axis vertical machining center.
[0056] Exemplarily, the driving member 130 is a linear motor.
