Description

Technical Field

[0001] This utility model relates to the field of gantry frame technology, and in particular to a gantry frame for a flip-up gantry milling machine. Background Technology

[0002] A gantry milling machine, also known as a gantry milling machine, is a milling machine with a gantry frame and a horizontal long bed. Multiple milling cutters can be used to process surfaces simultaneously on a gantry milling machine, resulting in high processing accuracy and production efficiency. It is suitable for processing the planes and inclined surfaces of large workpieces in batch and mass production. CNC gantry milling machines can also process spatial curved surfaces and some special-shaped parts. Gantry milling machines require a gantry frame to facilitate subsequent processing operations. A tilting gantry milling machine, disclosed in CN211162875U, includes a gantry body and a support column bottom connecting mechanism. Support columns A and B are symmetrically arranged on the gantry body. A crossbeam is provided between the crossbeam mounting slot A of support column A and the crossbeam mounting slot B of support column B. A milling head mounting slot is provided inside the crossbeam, communicating with a movable slot on the side of the crossbeam. A motor is located near the top of the outer side of support column B, with a threaded rod on the motor shaft. Both support columns A and B have a support column bottom connecting mechanism at their bottoms. Rollers are symmetrically arranged on both sides of the support column bottom connecting mechanism, and a retaining plate is provided at the bottom of the mechanism to firmly fix support columns A and B together. This device is reasonably designed, the gantry structure is stable, and the milling head can be tilted under the indirect drive of the crossbeam.

[0003] However, the existing tilting gantry milling machine has the following drawbacks: The existing technology uses a motor to drive the crossbeam to rotate vertically, thereby changing the tilt angle of the milling head and improving the flexibility of the gantry milling machine. However, in actual use, the above operation does not have a limit function, which makes it easy for the milling head to shift position during processing after adjustment, thus reducing the accuracy of the processing. Summary of the Invention

[0004] The purpose of this utility model is to provide a flip-up gantry milling machine gantry frame to solve the problem mentioned in the background art that the existing flip-up gantry milling machine gantry frames do not have a limiting function during use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a gantry frame for a flip-up gantry milling machine, comprising two gantry frame columns, a moving block, a locking block, rollers, and an adjusting block. The bottom ends of the two gantry frame columns are each welded with a moving block, and the bottom ends of the moving blocks are each fixed with a locking block. Rollers are rotatably connected to both sides of the bottom ends of the locking blocks. An adjusting block is provided at the top of each gantry frame column. Each of the adjusting blocks is equipped with a limit mechanism at its top. An auxiliary disk is rotatably connected to one side of one of the adjusting blocks, and a flipping motor is fixed to one side of the other adjusting block. A flipping shaft is fixed to one side of the flipping motor, and a fixed disk is welded to one end of the flipping shaft. A gantry frame cross plate is welded between the auxiliary disk and the fixed disk, and an adjusting motor is fixed inside the gantry frame cross plate. An adjusting shaft is fixed to one side of the adjusting motor, and a sliding block is sleeved on the outside of the adjusting shaft. A milling head mounting plate is welded to the bottom end of the sliding block, and an adjusting mechanism is provided inside each of the gantry frame columns.

[0006] Furthermore, the adjustment mechanism includes a hydraulic cylinder, which is located inside the gantry column. A push block is fixed to the top of the hydraulic cylinder, and push plates are welded to both sides of the top of the push block. The top of the push plate is fixedly connected to the adjustment block.

[0007] Furthermore, there are two push blocks, which are symmetrically distributed and have rectangular cross-sections. The outer edges of both push blocks slide against the inner wall of the gantry column.

[0008] Furthermore, the pusher plate is provided in two sets, with two pusher plates in each set, and the pusher plates in each set are symmetrically distributed.

[0009] Furthermore, the limiting mechanism includes an electric telescopic rod, which is disposed at the top of the adjusting block. A movable block is welded to one side of the electric telescopic rod, and a limiting rod is fixed to one side of the movable block. A guide block is disposed at the bottom of the movable block, and a guide groove is disposed on the outer side of the guide block, with the guide groove being opened inside the adjusting block.

[0010] Furthermore, there are two limiting rods, and each of the two limiting rods has a limiting groove on its outer side. The limiting grooves are opened inside the auxiliary plate and the fixed plate, and the limiting grooves are distributed in a ring shape.

[0011] Furthermore, there are two guide blocks and two guide grooves, and both guide blocks slide inside the guide grooves. The movable blocks are slidably connected to the adjusting blocks through the guide blocks and guide grooves.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the flip-up gantry milling machine not only has a limiting function, but also an adjustment function; 1. By activating the two electric telescopic rods, the two movable blocks move horizontally under the action of the guide block and guide groove, thereby causing the two limit rods to move horizontally relative to each other. Then, the two limit rods are inserted into the interior of the auxiliary plate and the fixed plate respectively. The above operation facilitates the limitation of the adjusted auxiliary plate and the fixed plate, thereby facilitating the limitation of the gantry cross plate, thus preventing the gantry cross plate from moving during the milling head's processing, and thus improving the processing accuracy. 2. By activating the hydraulic cylinder, the push plate is raised under the action of the push block. At the same time, the adjusting block is raised synchronously. The above operation makes it easy to adjust the height of the gantry cross plate according to the actual use, thereby improving its practicality. 3. By starting the adjusting motor, the position of the milling head mounting plate can be easily adjusted left and right according to the actual usage situation under the action of the adjusting shaft and the sliding block. At the same time, by starting the flipping motor, the fixed plate rotates under the action of the flipping shaft, and the gantry cross plate rotates under the action of the auxiliary plate. Through the above operations, the milling head mounted on the milling head mounting plate can be flipped according to the actual usage situation, thereby improving its flexibility.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please see Figures 1-5 The present invention provides the following technical solution: Example 1

[0018] To address the lack of limit function in existing technologies, the following technical solution is proposed. Please refer to the following for details. Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a tilting gantry milling machine gantry includes two gantry columns 1, a movable block 3, a locking block 4, rollers 5, and an adjusting block 6. Movable blocks 3 are welded to the bottom ends of both gantry columns 1, and locking blocks 4 are fixed to the bottom ends of both movable blocks 3. Rollers 5 are rotatably connected to both sides of the bottom end of the locking blocks 4. Adjusting blocks 6 are provided at the top ends of both gantry columns 1, and limit mechanisms 7 are provided at the top ends of both adjusting blocks 6. The limit mechanism 7 includes an electric telescopic rod 701, which is located at the top end of the adjusting block 6. A movable block 703 is welded to one side of the electric telescopic rod 701. A fixed limit rod 704 is provided. A guide block 705 is provided at the bottom of the movable block 703. A guide groove 702 is provided on the outer side of the guide block 705 and is opened inside the adjusting block 6. Two limit rods 704 are provided. A limit groove is provided on the outer side of each of the two limit rods 704. The limit groove is opened inside the auxiliary plate 8 and the fixed plate 12. The limit groove is distributed in a ring. Two guide blocks 705 and two guide grooves 702 are provided. Both guide blocks 705 slide inside the guide grooves 702. The movable block 703 is slidably connected to the adjusting block 6 through the guide blocks 705 and the guide grooves 702.

[0019] In this embodiment, the milling head is mounted on the milling head mounting plate 15. The adjusting motor 9 is activated, causing the adjusting shaft 16 to rotate. The sliding block 11 causes the milling head mounting plate 15 to move horizontally left and right. This allows for easy adjustment of the milling head's position according to actual usage, facilitating processing of different workpiece positions. Simultaneously, the flipping motor 14 is activated, causing the flipping shaft 13 to rotate. This rotation of the flipping shaft 13 causes the fixed plate 12 to rotate, and the auxiliary plate 8 causes the gantry frame horizontal plate 10 to rotate. This rotation of the gantry frame horizontal plate 10, in turn, drives the milling head mounting plate 15 to rotate. This operation facilitates flipping the milling head mounted on the milling head mounting plate 15, allowing for processing of workpieces at different angles. After processing and adjustment, the two electric telescopic rods 701 are activated, causing the two movable blocks 703 to move horizontally relative to each other. Simultaneously, the movable blocks 703 move, causing the guide block 705 to slide within the guide groove 702. The guide block 705 serves two purposes: firstly, it limits the movement of the movable blocks 703, preventing positional deviation; secondly, it guides the movable blocks 703, improving their stability during movement. Simultaneously, the movement of the movable blocks 703 pushes the limiting rods 704 horizontally, causing the two limiting rods 704 to insert into the auxiliary disk 8 and the fixed disk 12 respectively. This operation facilitates the limiting of the adjusted auxiliary disk 8 and fixed disk 12, preventing positional movement and improving the accuracy of workpiece processing. Example 2

[0020] This embodiment differs from Embodiment 1 in that it also has an adjustment function during use. Therefore, the following technical solution is disclosed. Please refer to it for details. Figure 1 , Figure 5As shown, an auxiliary disk 8 is rotatably connected to one side of an adjusting block 6, and a tilting motor 14 is fixed to one side of another adjusting block 6. A tilting shaft 13 is fixed to one side of the tilting motor 14, and a fixed disk 12 is welded to one end of the tilting shaft 13. A gantry frame cross plate 10 is welded between the auxiliary disk 8 and the fixed disk 12, and an adjusting motor 9 is fixed inside the gantry frame cross plate 10. An adjusting shaft 16 is fixed to one side of the adjusting motor 9, and a sliding block 11 is sleeved on the outside of the adjusting shaft 16. A milling head mounting plate 15 is welded to the bottom end of the sliding block 11. An adjusting mechanism 2 is provided inside each of the gantry frame columns 1. Mechanism 2 includes a hydraulic cylinder 201, which is located inside the gantry column 1. A push block 202 is fixed to the top of the hydraulic cylinder 201, and push plates 203 are welded to both sides of the top of the push block 202. The top of the push plate 203 is fixedly connected to the adjusting block 6. There are two push blocks 202, which are symmetrically distributed and have rectangular cross sections. The outer edges of the two push blocks 202 slide against the inner wall of the gantry column 1. There are two sets of push plates 203, with two push plates 203 in each set, and each set of push plates 203 is symmetrically distributed.

[0021] In this embodiment, the hydraulic cylinder 201 is activated to push the push block 202 to move upward. At the same time, the push block 202 pushes the push plate 203 to move upward synchronously, thereby causing the adjusting block 6 to move upward. While the adjusting block 6 is moving upward, the height of the milling head mounted on the milling head mounting plate 15 can be easily adjusted under the action of the gantry cross plate 10. The above operation makes it easy to adjust the height of the milling head according to the actual use situation, thereby improving its practicality and adapting to different use situations.
