Description

Technical Field

[0001] This utility model relates to the field of gantry milling machine technology, and in particular to a gantry milling machine for machining flange end faces. Background Technology

[0002] Flanges, typically disc-shaped or ring-shaped structures with bolt holes, are critical components in pipelines, equipment, or machinery used for connection, sealing, or support. The machining accuracy of their end faces directly affects the sealing performance, load-bearing capacity, and operational safety of the equipment.

[0003] Conventional gantry milling machines often use general-purpose vises or clamping plates to clamp flanges. The uneven distribution of clamping force can easily cause the flange to shift slightly or vibrate under cutting force, resulting in chatter marks on the machined surface, which is difficult to meet the requirements of high-precision machining. Utility Model Content

By using a push-pull cylinder to drive the circular drive disc to rotate, the four arc-shaped clamping plates can be closed together, and the inner wall of the arc-shaped clamping plates can better fit the outer wall of the flange to form a stable clamping of the flange.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0027] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] Please see Figures 1 to 6 The present invention relates to a gantry milling machine for machining flange end faces, comprising a milling machine body 10 and a clamping assembly 20 mounted on the milling machine body 10.

[0030] The milling machine body 10 includes a machining bed 11, a gantry 12 movably connected to the machining bed 11, and a spindle box 13 mounted on the gantry 12; a milling cutter is mounted at the end of the spindle box 13, and the milling cutter is used to cut the end face of the flange.

[0031] The clamping assembly 20 includes a support platform 21 mounted on the machining bed 11, a circular drive disk 22 rotatably mounted on the bottom surface of the support platform 21, a push-pull cylinder 23 connected to one side of the circular drive disk 22, four arc-shaped clamping plates 24 slidably mounted at even intervals on the top surface of the support platform 21, and pads 25 installed between adjacent arc-shaped clamping plates 24. The pads 25 support flanges located between the four arc-shaped clamping plates 24. The four arc-shaped clamping plates 24 are arranged in a circumferential array along the center of the circular drive disk 22, and the direction of movement of the arc-shaped clamping plates 24 is consistent with the radial direction of the circular drive disk 22. The arc-shaped clamping plates 24 slide downwards to connect with the circular drive disk 22, which drives the four arc-shaped clamping plates 24 to move closer together or further apart.

[0032] Specifically, such as Figure 5 and Figure 6 As shown, the circular drive disc 22 has four arc-shaped grooves 220 extending outward from its center at even intervals. Arc-shaped clamping plates 24 are slidably connected to the top surface of the support platform 21 via guide rails. A pulley 240 is connected to the bottom end of each arc-shaped clamping plate 24, and the pulley 240 passes through the support platform 21 and fits into the groove 220. By using a push-pull cylinder 23 to drive the circular drive disc 22 to rotate, the four arc-shaped clamping plates 24 can close together, allowing the inner wall of the arc-shaped clamping plates 24 to better conform to the outer wall of the flange, thus forming a stable clamping effect on the flange.

[0033] In this embodiment, the support platform 21 is provided with four through holes 210 at even intervals. The through holes 210 are arranged one-to-one below the arc-shaped clamping plate 24 and are used for the pulleys 240 to pass through.

[0034] In this embodiment, the clamping assembly 20 further includes a tension sensor 26 connected between the circular drive disk 22 and the push-pull cylinder 23. The tension sensor 26 is used to detect the tension applied by the push-pull cylinder 23 to prevent the push-pull cylinder 23 from pulling too much and causing the arc-shaped clamping plate 24 to over-clamp the flange, resulting in damage to the arc-shaped clamping plate 24.

[0035] In this embodiment, in order to improve the stability of the movement of the circular drive disk 22, the clamping assembly 20 also includes a plurality of track wheels 27 rotatably mounted on the bottom surface of the support platform 21, and the track wheels 27 are evenly spaced and abut against the periphery of the circular drive disk 22.

[0036] The gantry milling machine for machining the flange end face described above has a simple structure and is easy to use. By using the push-pull cylinder 23 to drive the circular drive disk 22 to rotate, the four arc-shaped clamping plates 24 can be closed together, and the inner wall of the arc-shaped clamping plates 24 can better fit the outer wall of the flange to form a stable clamping of the flange.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
