[0001] This utility model relates to a gantry milling machine, and more particularly to a gantry milling machine for CNC machining of metal rods. Background Technology

[0002] Gantry milling machines are suitable for machining large and heavy workpieces, as well as complex parts requiring large-area and multi-faceted machining. They are particularly adept at handling the following types of workpieces: large plate / box-type parts, molds / templates, structural parts / frames, and irregularly shaped parts / complex curved surfaces. Chinese utility model patent application number 202320718632.6 provides a worktable for machining small, tightly packed steel structural members. This patent describes a "movable flange support plate that slides horizontally along a slide rail, working with external precision measuring equipment to ensure accurate flange positioning and machining precision; the bracket can select different support positions according to different member lengths, and the arc-shaped recess and bearing at the top of the bracket further facilitate support for the member." However, this patent has the following shortcomings: First, it relies too heavily on the flange for clamping members, making it difficult to effectively clamp members without flanges; second, it cannot radially clamp members, failing to guarantee stable member positions; third, if applied to milling operations, it is difficult to perform multi-angle circumferential angle adjustments. Utility Model Content

[0003] The purpose of this utility model is to provide a gantry milling machine for CNC machining of metal rods to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A CNC gantry milling machine for machining metal rods includes a CNC gantry milling machine body and a worktable. The worktable is mounted on the CNC gantry milling machine body, and a mounting base is detachably mounted on the worktable. At least two clamping mechanisms and at least two clamping mechanisms are detachably mounted on the mounting base. Each clamping mechanism includes a lower clamping seat, an upper clamping seat, a V-groove, clamping bolts, and clamping nuts. The lower clamping seat is detachably mounted to the mounting base. Detachable and vertical clamping bolts are inserted into the left and right parts of the lower clamping seat, respectively. Clamping nuts are threaded onto the upper part of each clamping bolt. The two clamping bolts on the left and right parts of the lower clamping seat are jointly inserted into the upper clamping seat. V-grooves are provided at the top and bottom of the lower clamping seat, respectively. The V-grooves of the upper and lower clamping seats correspond vertically. The V-grooves of each clamping mechanism... The clamping nuts are aligned front to back and can be tightened against the top of the upper clamping seat. The tightening mechanism includes a tightening seat, a tightening plate, guide cylinders, guide rods, adjusting screws, and adjusting nuts. The tightening seat is detachably installed with the mounting base. The tightening seat is fixed with multiple guide cylinders extending horizontally in the front-back direction. The guide cylinders are axially penetrating through the seat. The end of the tightening plate near the tightening seat is fixed with multiple guide rods extending horizontally in the front-back direction and an adjusting screw. Each guide rod is slidably connected to each guide cylinder in the front-back direction. The adjusting screw is parallel to the guide rods and is inserted into the tightening seat through a gap. The adjusting screw is coaxially threaded with at least two adjusting nuts. The two adjusting nuts on the same adjusting screw are located on the front and back sides of the same tightening seat and tighten the same tightening seat. The tightening plate and the V-groove are aligned front to back.

[0005] Based on the above technical solution, the worktable includes an inverted T-slot, limiting holes, limiting bolts, mounting holes, mounting bolts, and mounting nuts. The worktable has an inverted T-slot extending through its front and rear ends, with the upper part of the inverted T-slot extending to the top of the worktable. Multiple limiting holes are opened at both ends of the worktable, and these limiting holes are equidistantly arranged along the front-rear direction. Multiple limiting bolts are threaded through the left and right sides of the mounting base. The outer wall of the shank of the limiting bolts, away from the head, is smooth and engages with the limiting holes. Multiple mounting nuts extend through the top and bottom of the mounting base. The mounting holes are arranged at equal intervals along the front-to-back direction. Vertical mounting bolts are inserted through the lower clamping seat and the top clamping seat respectively. The head of the mounting bolt is inserted into the inverted T-slot with a gap, and the left and right sides of the head are in contact with the left and right sides of the bottom inner wall of the inverted T-slot. The head of the mounting bolt can tighten the inverted T-slot. The mounting bolt can be inserted through different mounting holes. The shank of the mounting bolt is threaded with a mounting nut, and the mounting nut is tightened against the bottom of the lower clamping seat and the top clamping seat.

[0006] Based on the above technical solution, the CNC machining gantry milling machine for metal rods further includes a circumferential angle mechanism. The circumferential angle mechanism includes a support ring, a through hole, a tightening bolt, and circumferential angle scales. The support ring has a through hole in the middle, which is a regular polygonal prism. The virtual axis of the support ring and the virtual geometric axis of the through hole are horizontally arranged in the front-back direction, and there are at least three tightening bolts connected by circumferentially equal-angle through threads. The tightening bolts are perpendicular to the inner wall of the through hole. The front and rear ends of the support ring are respectively provided with multiple circumferential angle scales at equal angles.

[0007] Compared with the prior art, the present invention has the following advantages: The present invention enables the top clamping plate to lightly clamp the rod, and then the upper clamping seat, clamping bolt and clamping nut are reinstalled, so that the upper clamping seat clamps the rod with the V-groove, and then the adjusting nut is rotated, and the top clamping plate is used to tighten the rod, so that the rod can be effectively clamped. By using the matching of the limiting hole and the limiting bolt, and by tightening the mounting bolt against the inverted T-slot, the mounting base can be well secured, thereby ensuring the stability of the rod's position. The support ring is fitted onto the outside of the rod, and then tightened onto the outer circumferential wall of the rod using the tightening bolt. The circumferential angle of the rod can be adjusted by observing the position of the circumferential angle scale relative to the cutting tool. Attached Figure Description

An adjusting screw 15 is provided, and each of the guide rods 14 is slidably connected to each of the guide cylinders 13. The adjusting screw 15 is parallel to the guide rods 14 and is inserted through the clamping seat 11. The adjusting screw 15 is coaxially threaded with at least two adjusting nuts 16. The two adjusting nuts 16 on the same adjusting screw 15 are located on the front and rear sides of the same clamping seat 11 and clamp the same clamping seat 11. The clamping plate 12 corresponds to the V-groove 8.

[0016] In use, first remove the upper clamping seat 7, clamping bolt 9, and clamping nut 10. Then place the rod on the V-groove 8 of the lower clamping seat 6. Then, use a wrench or other tools to rotate the adjusting nut 16 so that the top clamping plate 12 lightly clamps the rod. Then, reinstall the upper clamping seat 7, clamping bolt 9, and clamping nut 10 so that the upper clamping seat 7 clamps the rod using the V-groove 8. Then, rotate the adjusting nut 16 to tighten the rod using the top clamping plate 12, thus achieving effective clamping of the rod.

[0017] The workbench 2 includes an inverted T-slot 17, limiting holes 18, limiting bolts 19, mounting holes 20, mounting bolts 21, and mounting nuts 22. The inverted T-slot 17 extends through the workbench 2 from front to back, with the upper part of the inverted T-slot 17 extending to the top of the workbench 2. Multiple limiting holes 18 are opened at both ends of the workbench 2, and the limiting holes 18 are arranged at equal intervals along the front-back direction. Multiple limiting bolts 19 are threaded through the left and right sides of the mounting base 3. The outer wall of the rod of the limiting bolt 19 away from the head is smooth and fits into the limiting hole 18. Multiple mounting holes 20 extend through the mounting base 3 from top to bottom. The mounting holes 20 are arranged at equal intervals along the front-to-back direction.

The shank of the mounting bolt 21 is threaded with a mounting nut 22, and the mounting nut 22 is tightened against the bottom of the lower clamping seat 6 and the top clamping seat 11.

[0018] Furthermore, the mounting base 3 can be well secured by the cooperation of the limiting hole 18 and the limiting bolt 19, as well as the tightening of the mounting bolt 21 against the inverted T-slot 17, thereby ensuring the stability of the position of the rod.

[0019] The CNC machining gantry milling machine for metal rods also includes a circumferential angle mechanism, which includes a support ring 23, a through hole 24, a tightening bolt 25, and circumferential angle scales 26.

[0020] Furthermore, the support ring 23 is fitted onto the outside of the rod, and then tightened onto the outer circumferential wall of the rod using the tightening bolt 25. By measuring the distance from the side wall of the through hole 24 to the outer circumferential wall of the rod, the distance is made to be consistent, so that it is coaxial with the rod. By observing the position of the circumferential angle scale 26 relative to the tool, the circumferential angle of the rod can be adjusted.
