Description

Technical Field

[0001] This invention belongs to the field of tooling inventions, and particularly relates to a five-axis tilting head disassembly and assembly device for a CNC gantry machining center and its usage method. Background Technology

[0002] In the machining industry, the five-axis swivel head is a key component of a five-axis machining center, and its accuracy and stability directly affect the quality of the machined products. After prolonged use, the five-axis swivel head inevitably experiences wear and tear on its parts, requiring disassembly, repair, or replacement of components.

[0003] However, existing methods for disassembling and assembling five-axis oscillating heads have many problems. Traditional disassembly methods often rely on manual force, which can easily damage the tightly fitted components of the five-axis oscillating head, affecting its subsequent accuracy and lifespan. Furthermore, manual disassembly is inefficient, increasing labor costs and downtime. During assembly, the lack of assembly fixtures makes the positioning and assembly of parts difficult, making it hard to guarantee assembly accuracy. This can lead to problems such as unstable operation and accuracy deviations after assembly, failing to meet production requirements. Therefore, designing a device that can efficiently and accurately disassemble and assemble five-axis oscillating heads is of significant practical importance. Summary of the Invention

[0004] To address the problems of existing disassembly methods relying on manual force, which easily damages the tightly fitted components of the five-axis swivel head, and the low efficiency of manual disassembly, increasing labor costs and downtime; and the lack of assembly tooling during the assembly process, which makes the positioning and assembly of parts difficult, this invention provides a disassembly and assembly device and its method for a five-axis swivel head of a CNC gantry machining center. The technical solution is as follows:

[0005] In one aspect, a five-axis swivel head disassembly and assembly device for a CNC gantry machining center is provided, comprising: a connector 1, a pressure plate 2, a front bracket 3, a support plate 4, a slider 5, a drive component 7, a first transmission component 6, a second transmission component 8, a bracket 9, and a support rod 10. The bracket 9 is placed on the worktable of the CNC gantry machining center. The second transmission component 8 and the support rod 10 are fixed to the upper plane of the bracket 9. The transmission component 6 is hinged to the slider 5, and the support rod 10 is hinged to the support plate 4. The slider 5 is placed in a slot on the lower plane of the support plate 4. The front bracket 3 is fixed to the support plate 4. To ensure that the fixture is applicable to the disassembly and assembly of five-axis heads of different sizes, the support plate 4 and the front bracket can be fixed by bolt fastening or other methods, ensuring that the front bracket 3 and the support plate 4 can be separated, and that a support plate 4 with a suitable hole diameter can be selected and installed on the front bracket 3 according to the size of the five-axis head.

[0006] By rotating the drive component 7, the first transmission component 6 is driven, and the second transmission component 8 is vertically raised and lowered. The slider 5 then slides within the slot on the lower plane of the support plate 4, causing the support plate 4 to rotate around the top of the support rod 10. This changes the spatial angle and position of the support plate 4 until it is parallel to the stop position of the five-axis head. When fixing the five-axis head 11, the linear axis of the device is moved so that the front end of the A-axis is directly placed against the front of the front bracket 3. Then, a suitable position for the five-axis head is selected. Each side of the support plate 4 has a through-hole. A screw passes through the through-hole and engages with the pressure plate 2, and is then tightened with bolts to clamp and fix the five-axis head.

[0007] Optionally, the bracket 9 is made of high-strength steel, which has sufficient rigidity and strength.

[0008] Optionally, the front bracket 3 is a plate structure with a through circular hole for threaded connection with the bracket 4, facilitating disassembly and replacement.

[0009] Optionally, the support plate 4 has a long groove on one side, in which the slider 5 can move. The support plate 4 has two through-holes, and the screw passes through the long groove to engage with the pressure plate 2 and is fastened with bolts to achieve clamping and fixing of the five-axis head.

[0010] Optionally, the rotating drive component 7 drives the first transmission component 6 and the second transmission component 8 to work. The first transmission component 6 and the second transmission component 8 can be a lead screw and nut structure, a hydraulic lifting mechanism, a pneumatic lifting mechanism, etc.

[0011] Optionally, the support rod 10 is fixed to the bracket 9 by means of threading, welding, gluing, etc.

[0012] Optionally, the support rod 10 is made of high-strength steel, possessing sufficient rigidity and strength. The support rod 10 is connected to the support plate 4 by a hinge.

[0013] Secondly, a method for using a five-axis tilting head disassembly and assembly device for a CNC gantry machining center is provided, including:

[0014] The disassembly process is as follows:

[0015] Place the device on the worktable of the five-axis machining center and fix its bottom to prevent it from tilting.

[0016] Based on the stop position of the five-axis oscillating head, rotate the drive component 7 to drive the first transmission component 6 and the second transmission component 8 to move up and down, and drive the slider 5 to move in the groove on the lower plane of the support plate 4, so that the five-axis head is parallel to the upper plane of the support plate 4.

[0017] The five-axis head of the mobile device X / Y / Z linear axis is placed on the support plate 4. The front end of the five-axis head is close to the front bracket 3. At the center of the five-axis head, the screw is passed through the long holes on both sides of the support plate 4 and combined with the nut to tighten the pressure plate (2) to achieve the clamping and fixing of the five-axis head and achieve the purpose of fixing the five-axis head.

[0018] Use the appropriate tools to disassemble the components of the five-axis oscillating head;

[0019] The assembly process is as follows:

[0020] Place the five-axis head to be assembled in a suitable position on this device, ensuring that the front end of the five-axis head is close to the front bracket. At the center of the five-axis head, pass the screw through the long holes on both sides of the bracket 4 and engage with the nut to tighten the pressure plate 2, thereby clamping and fixing the five-axis head.

[0021] Rotate the drive component 7 to drive the first transmission component 6 and the second transmission component 8 to move up and down, adjusting the five-axis head to the appropriate assembly position and angle;

[0022] Move the X / Y / Z linear axes of the mobile device to the appropriate position of the Z-axis slide of the device for five-axis head installation;

[0023] After installation, loosen components such as pressure plate 2 and front bracket 3, remove the device, and proceed with subsequent debugging and testing.

[0024] The beneficial effects of this application are as follows:

[0025] Compared to traditional manual operation, the use of this device improves the efficiency of disassembling and installing five-axis oscillating heads, reduces collisions and friction between parts, and effectively ensures the tightness of the five-axis oscillating head components. Furthermore, the components of this device can be adjusted and replaced according to different sizes of five-axis oscillating heads, exhibiting strong versatility and being suitable for disassembling and assembling various sizes and specifications of five-axis heads.
