Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a lifting structure for the upper saddle of a machine tool. Background Technology

[0002] Five-axis laser CNC machine tools, as a high-end manufacturing equipment, integrate multi-axis linkage control technology and laser processing technology, giving them an important position in modern manufacturing.

[0003] The bed of the five-axis laser CNC machine tool provides a solid support foundation for the entire machine tool, ensuring that all components can be securely installed on it. In order to enable the laser processing module to move along the Z-axis, the laser processing module is slidably mounted on the upper saddle of the bed. However, since the upper saddle needs to provide a space for the fixture to slide, it must be supported by two columns. To adjust the pitch and tilt of the upper saddle, a shim is placed between the upper saddle and the columns. During the debugging process, the shim needs to be removed and reinstalled multiple times. That is, depending on the installation effect, the shim is removed, adapted, and then reinstalled. However, when removing and reinstalling the shim, the upper saddle needs to be lifted and disassembled at the same time. Since the upper saddle will shake and shift after being lifted, it must be re-aligned and reassembled afterward. The debugging process is tedious and time-consuming.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an upper saddle body lifting structure, which is designed to facilitate the lifting of the upper saddle body when disassembling and assembling the pad.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A machine tool upper saddle lifting structure includes two spaced columns on the machine bed and an upper saddle mounted above the columns. A pad and a support plate are provided between the two legs of the upper saddle and the corresponding columns. In a top view, the support plate extends laterally and its two ends extend outwards from the support legs. Each column has a lifting assembly on its left and right sides. The two lifting assemblies together lift the support plate upwards, so that the upper saddle rises and disengages from the pad.

[0008] As a further improvement to the above technical solution, the lifting assembly includes a fixing block fixed on the side of the column and a lifting screw threadedly connected to the fixing block and pointing vertically upward toward the support plate.

[0009] As a further improvement to the above technical solution, the lifting screw is a hexagonal screw.

[0010] As a further improvement to the above technical solution, the lifting screw is a hand-tightening screw.

[0011] As a further improvement to the above technical solution, the lifting assembly includes a linear driver that is vertically upward toward the support plate and a top head disposed at the output end of the linear driver.

[0012] As a further improvement to the above technical solution, the linear actuator is one of a hydraulic cylinder, an electric cylinder, and a pneumatic cylinder.

[0013] As a further improvement to the above technical solution, the support plate is located at the middle of the bottom surface of the support leg of the upper saddle body, and two pads are provided at the bottom of each support leg of the upper saddle body, with the two pads located on the front and rear sides of the support plate respectively.

[0014] As a further improvement to the above technical solution, the upper saddle body is provided with two vertically downward countersunk holes at the outriggers, each pad is provided with a through hole coaxial with the corresponding countersunk hole, and the top surface of the column is provided with a threaded hole coaxial with the countersunk hole and the through hole. The mounting screw passes through the countersunk hole and the through hole from top to bottom and then connects to the threaded hole.

[0015] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model uses a lifting assembly and a support plate to directly lift the upper saddle body away from the pad plate, which makes it easy to disassemble and assemble the pad plate. This eliminates the need for frequent disassembly and hoisting of the upper saddle body, simplifies the debugging process, reduces labor intensity, and improves work efficiency.

[0020] This utility model provides a lifting structure for the upper saddle of a machine tool. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0021] Please see Figures 1-3This utility model provides a lifting structure for the upper saddle of a machine tool, including two spaced columns 1 on the machine bed and an upper saddle 2 mounted above the columns 1. A pad 3 and a support plate 4 are provided between the two legs 21 of the upper saddle 2 and the corresponding columns 1. In a top view, the support plate 4 extends laterally and its two ends extend outward from the legs 21. Each column 1 has a lifting component 5 on its left and right sides. The two lifting components 5 together lift the support plate 4 upward so that the upper saddle 2 rises and disengages from the pad 3.

[0022] When it is necessary to replace the pad 3 or perform other maintenance operations, the operator manipulates the lifting assembly 5. The two lifting assemblies 5, through the support plate 4, smoothly lift one of the legs of the upper saddle 2 upwards until the leg of the upper saddle 2 is completely detached from the pad 3, creating a gap between the upper saddle 2 and the column 1, allowing the pad 3 to be removed. In this way, the pad 3 can be easily removed to adjust the pitch and tilt of the upper saddle 2 without hoisting or moving the entire upper saddle 2. After the pad 3 is re-processed and adjusted, it is reinstalled between the upper saddle 2 and the column 1. Finally, the lifting assembly 5 controls the upper saddle 2 to lower down, so that its leg contacts the pad 3 again, completing one adjustment cycle.

[0023] Compared with the prior art, this utility model uses the lifting component 5 and the support plate 4 to directly lift the upper saddle body 2 away from the pad plate 3, which makes it easy to disassemble and assemble the pad plate 3. This eliminates the need for frequent disassembly and hoisting of the upper saddle body 2, simplifies the debugging process, reduces labor intensity, and improves work efficiency.

[0024] In one embodiment, the lifting assembly 5 includes a fixing block 51 fixed to the side of the column 1 and a lifting screw 52 threadedly connected to the fixing block 51 and vertically upward toward the support plate 4. The combination of the fixing block 51 and the lifting screw 52 results in a simple structure. After the lifting screw 52 tightens onto the support plate 4, the weight of the upper saddle 2 and the support plate 4 is borne by the lifting screw 52. Tightening the lifting screw 52 controls the raising and lowering of the upper saddle 2. The threaded rotation of the lifting screw 52 allows for precise control of the lifting height, enabling fine-tuning.

[0025] Preferably, the lifting screw 52 is a hexagonal screw. Hexagonal screws, when used with a wrench or other special tools, can be tightened and loosened more easily, and turning hexagonal screws requires less effort.

[0026] Preferably, the lifting screw 52 is a hand-tightening screw, specifically a Torx head hand-tightening screw or a claw head hand-tightening screw. Hand-tightening screws do not require additional tools; operators can directly tighten them by hand, simplifying the operation process and improving work efficiency.

[0027] In another embodiment, the lifting assembly 5 includes a linear actuator pointing vertically upward toward the support plate 4 and a pusher head disposed at the output end of the linear actuator. The linear actuator drives the pusher head to lift the upper saddle body 2 on the support plate 4. The linear actuator is one of a hydraulic cylinder, an electric cylinder, or a pneumatic cylinder. Hydraulic cylinders, electric cylinders, and pneumatic cylinders all have strong driving force and can provide sufficient thrust to lift the upper saddle body 2, ensuring the smooth progress of the lifting process.

[0028] In this embodiment, the support plate 4 is located at the center of the bottom surface of the support leg 21 of the upper saddle body 2. Two pads 3 are provided at the bottom of each support leg 21 of the upper saddle body 2, with the two pads 3 located on the front and rear sides of the support plate 4, respectively. Having one pad 3 on each side allows for independent adjustment of the height of each pad 3, thus enabling more flexible adjustment of the posture of the upper saddle body 2, especially when adjusting pitch and tilt, achieving ideal Z-axis accuracy. Furthermore, it better distributes the weight of the upper saddle body 2, making the force more even and avoiding deformation or damage caused by excessive local pressure.

[0029] After the upper saddle body 2 is adjusted, the upper saddle body 2, the pad 3, and the column 1 need to be fixed together. Therefore, the upper saddle body 2 has two vertically extending countersunk holes 22 at the support leg 21. Each pad 3 has a through hole coaxial with the corresponding countersunk hole 22. The top surface of the column 1 has a threaded hole coaxial with the countersunk hole 22 and the through hole. The mounting screw passes through the countersunk hole 22 and the through hole from top to bottom and then connects to the threaded hole. The upper saddle body 2, the pad 3, and the column 1 are fixed together by the mounting screws to form a stable whole, ensuring processing stability.

[0030] It should be noted that the thickness of the pad 3 is greater than that of the support plate 4. Under normal machine conditions, the support plate 4 will not interfere with the pad 3 supporting the upper saddle body 2.
