Description

Technical Field

[0001] This utility model relates to a side column structure, and in particular to a stable shape structure for the side column of a bridge gantry crane. Background Technology

[0002] Compared to conventional machining centers, five-axis machining centers offer more selectable machining axes, thus meeting more diverse and challenging machining needs. Therefore, they are widely used in related processing industries. Taking a gantry machining center as an example, a typical gantry machining center mainly consists of a crossbeam and two columns. The two ends of the crossbeam are connected to the columns, which provide good support for the crossbeam. A machining spindle is mounted on the crossbeam and can move along it to perform machining operations on the workpiece.

[0003] However, since most of these columns are square prisms (the width and thickness of the top and bottom of the column are the same), the overall support of the structure is not stable enough. When the machining spindle is performing cutting operations, the vibration often causes the entire structure to resonate, and long-term vibration can easily lead to structural damage.

[0004] In view of this, based on the author's many years of experience in manufacturing, developing and designing related products, and after detailed design and careful evaluation for the above objectives, the author has finally come up with a practical utility model. Utility Model Content

[0005] The purpose of this utility model is to provide a stable external shape structure for the side columns of a bridge gantry crane. Its structure is simple, operation and maintenance are convenient, and it can effectively overcome the defects of the prior art, improve the overall structural strength, and reduce the generation of resonance.

[0006] To achieve the above objectives, this utility model discloses a side column stabilizing shape structure for a bridge-type gantry crane, characterized by comprising:

[0007] A column body includes a connecting portion and a supporting portion. The connecting portion has a top section and a bottom section arranged opposite to each other along a first direction. The distance between the top section and the bottom section defines a first height. The connecting portion has a first inner surface and a first outer surface arranged opposite to each other along a second direction perpendicular to the first direction. The distance between the first inner surface and the first outer surface defines a first width. The supporting portion is integrally connected to the bottom of the connecting portion. The distance between the bottom surface of the supporting portion along the first direction and the bottom section defines a second height. The first height is greater than the second height. The supporting portion has a second inner surface and a second outer surface arranged opposite to each other along the second direction. The distance between the second inner surface and the second outer surface defines a second width. The second width is greater than the first width. The top edge of the second outer surface extends upward toward the connecting portion with an inclined surface, which connects to the bottom section.

[0008] The joint has a first outer end face at each end along a third direction perpendicular to the first and second directions. The distance between the two first outer end faces is defined as a first length. The bottom edge of each first outer end face extends downward toward each bottom segment to form an inclined surface, and a connecting surface is defined between each inclined surface and the bottom segment. Each inclined surface is connected to each connecting surface. The support has a second outer end face at each end along the third direction. The distance between the two connecting surfaces and the distance between the two second outer end faces together define a second length. The first length is greater than the second length.

[0009] The ratio of the first length to the second length is 1.1:1.

[0010] Wherein, the first direction is the Z-axis direction, the second direction is the X-axis direction, and the third direction is the Y-axis direction.

[0011] The ratio of the first height to the second height is 1.3:1.

[0012] The ratio of the first width to the second width is 1:1.2.

[0013] The top surface of the joint is provided with at least one slide rail, which is used to assemble the end of the crossbeam so that the crossbeam can move relative to the column body.

[0014] With the above structure, the inclined surface of the support part makes the bottom width of the column body wider than the top width, which can improve its overall structural strength. Compared with the columns of existing gantry machining machines, it provides better structural stability and good support effect, and can reduce the generation of resonance.

[0019] Please see Figures 1 to 4 As shown, this utility model discloses a side column stabilizing shape structure for a bridge-type gantry crane, used to connect to a crossbeam 20, which includes:

[0020] A column body 10 includes a connecting portion 11 and a supporting portion 12. The top surface of the connecting portion 11 is provided with at least one slide rail 111, which is used to assemble the end of a crossbeam 20, allowing the crossbeam 20 to move relative to the column body 10. The connecting portion 11 has a top section 114 and a bottom section 115 arranged opposite each other along a first direction. The distance between the top section 114 and the bottom section 115 is defined as a first height H1. The connecting portion 11 extends along a direction perpendicular to the first direction. The first direction and the second direction have a first inner surface 117 and a first outer surface 118 disposed opposite to each other. The distance between the first inner surface 117 and the first outer surface 118 is defined as a first width W1. The joint portion 11 has a first outer end face 112 at each end along a third direction perpendicular to the first direction and the second direction. The distance between the two first outer end faces 112 is defined as a first length L1. The bottom edge of each first outer end face 112 extends downward toward each bottom segment 115. An inclined surface 113 is formed, and a connecting surface 116 is defined between each inclined surface 113 and the bottom section 115. The inclined surface 113 is connected to each connecting surface 116. The support part 12 is integrally connected to the lower part of the joint 11 to provide overall support for the column body 10. The distance between the bottom surface of the support part 12 and the bottom section 115 along the first direction defines a second height H2, and the support part 12 has a second inner surface 121 disposed opposite to it along the second direction. The second outer surface 122 is defined by a second width W2, and the top edge of the second outer surface 122 extends upward toward the joint 11 with a slope 123, which is connected to the bottom section 115. In addition, the support portion 12 has a second outer end face 124 at each end along the third direction, and the distance between the two connecting surfaces 116 and the distance between the two second outer end faces 124 is defined by a second length L2.

[0021] The first height H1 is greater than the second height H2, and the ratio of the first height H1 to the second height H2 is approximately 1.3:1.

[0022] The second width W2 is greater than the first width W1, and the ratio of the first width W1 to the second width W2 is approximately 1:1.2.

[0023] Wherein, the first length L1 is greater than the second length L2, and the ratio of the first length L1 to the second length L2 is approximately 1.1:1.

[0024] Wherein, the first direction system is the Z-axis direction, the second direction system is the X-axis direction, and the third direction system is the Y-axis direction.

[0025] Continue reading Figure 4 and pair Figure 1 As shown, in actual use, the present invention has two column bodies 10. The two ends of the crossbeam 20 are respectively connected to the slide rails 111 via a slider 21, so that the crossbeam 20 can move in the third direction (Y-axis) on the column bodies 10. The crossbeam 20 is equipped with a machining spindle 30, which can move in the second direction (X-axis) on the crossbeam 20. At the same time, the machining spindle 30 can move in the first direction (Z-axis) to improve the flexibility and efficiency of machining.

[0026] Through the above structure, the inclined surface 123 of the support part 12 makes the width of the bottom of the column body 10 greater than the width of the top, thereby improving its overall structural strength. Compared with the columns of existing gantry machining machines, it provides better structural stability and good support effect, and can reduce the generation of resonance.
