Description

Technical Field

[0001] The invention belongs to the technical field of machine tool shaft head processing equipment and relates to a special installation device for a five-axis head production line. Background Art

[0002] A five-axis head refers to a machine tool accessory that can achieve five degrees of freedom (three linear axes and two rotary axes) linkage in CNC machining. This design enables the five-axis head to perform more complex operations on the workpiece during machining, including but not limited to milling, cutting, etc. The five-axis head usually contains three moving axes of x, y, and z and any two rotary axes (two of A, B, and C). This configuration allows the tool to be positioned and connected in five degrees of freedom, thereby machining complex geometric shapes. Five-axis machining can provide higher accuracy and precision, efficiency and reliability, allowing up to 5 faces to be manufactured in one operation, which is becoming more and more valuable for multiple industries. The five-axis head has become an indispensable part of modern manufacturing because it can provide efficient and precise machining of complex parts, especially in aerospace, mold manufacturing and other fields. my country has made certain progress in the field of five-axis linkage CNC machine tools. Five-axis linkage CNC machine tools have achieved a rapid transformation from research and development trial production to finalized mass production, and have made great progress in technology.

[0003] Since the five-axis head is mainly used for complex and high-precision parts processing, the accuracy needs to be checked during assembly, including the deviation of the distance from the spindle end face to the A-axis rotation center, the deviation of the swing fan of the swing head and the YZ plane, the height difference between the spindle axis and the A-axis axis, etc., to ensure the processing performance and processing quality. In order to reduce the error, a specific fixing mechanism is generally required when assembling the five-axis head. For example, the utility model patent [Patent No. 202220328088.X] published by China discloses a flip fixing device for disassembly and assembly of the five-axis head, including a base, the base is a frame with a workbench structure, a reducer fixing seat is installed on one side of the workbench of the base, a stop handwheel is installed above the reducer fixing seat, a planetary reducer is installed on the left side of the reducer fixing seat, and a drive shaft component is installed at the input end of the planetary reducer. The output end of the planetary reducer is connected to the rotating bracket, and the center of gravity of the rotating bracket is located below the rotation center of the planetary reducer. Two five-axis head installation adjustment plates are placed symmetrically on the rotating bracket. An arc opening is opened on one side of the extended edge of the installation adjustment plate, and several five-axis head installation holes of different sizes are distributed along the arc edge for the installation of various types of five-axis heads. The five-axis head to be disassembled or assembled is fixed on the five-axis head installation adjustment plate.

[0004] However, similar fixing mechanisms to the above require the cooperation of a crane. The crane is required to lift the five-axis head above the fixing mechanism, and then lower it to the limit frame and fix it to the fixing mechanism through bolts. After assembly, it is directly transferred to the inspection station by the crane without a protective frame, and it is easy to bump during the transfer. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a special installation device for a five-axis head production line. During assembly and inspection, the positioning plate is always fixed to the five-axis head. By ensuring that the positioning plate is in a horizontal state, the five-axis head can be in a vertical state, thereby improving the installation precision and detection accuracy.

[0006] The purpose of the present invention can be achieved through the following technical solutions: a special installation device for a five-axis head production line, comprising a vertical plate, a rotation adjustment component, a rotation lifting component, a transfer frame and a positioning plate that can be fixedly installed with the five-axis head, characterized in that the rotation lifting component is located between the two vertical plates, the rotation adjustment component comprises an angle adjustment disk and a mounting plate rotatably connected to the upper end of the vertical plate, the mounting plate is fixed to the inner side of the angle adjustment disk, the mounting plate has a mounting groove for the positioning plate to be inserted, the mounting groove and the positioning plate are both provided with aligned first bolt holes, and a driving angle adjustment disk is fixed to the outer side of one of the vertical plates The first rotating motor, the rotary lifting assembly includes a base, a rotating disk, a lifting cylinder and a second motor. The rotating disk is horizontally connected to the base. A driving gear is fixed on the output shaft of the second motor. A driven gear meshing with the driving gear is fixed on the rotating shaft of the rotating disk. A groove for the lifting cylinder to vertically engage is provided on the upper end surface of the rotating disk. A guide slope is provided at the front end of the base, and a linear guide rail is fixed on the guide slope. The forward extension section of the linear guide rail is a detection station. The transfer frame is arranged on the linear guide rail and can slide along the linear guide rail. The transfer frame has a detection groove for the positioning plate to be embedded.

[0007] Furthermore, the positioning plate is in the shape of a rectangular plate, with a limiting hole in the middle for the five-axis head to pass through, and a plurality of second bolt holes located around the limiting hole are also provided on the positioning plate, and the connecting flange of the five-axis head is fixed to the positioning plate by bolts passing through the second bolt holes.

[0008] Furthermore, the transfer frame includes a base plate, two side plates and a top plate. The base plate is fixedly connected to the top plate through the side plates. The detection groove is opened on the top plate. The base plate has a clearance hole for the lifting cylinder to pass through. The detection groove has a square hole for the five-axis head to pass through. A third bolt hole is opened at the bottom of the detection groove and is aligned with the first bolt hole of the positioning plate.

[0009] Furthermore, the lower end of the transfer rack has four supporting feet, and the supporting feet slide on the linear guide rail.

[0010] Furthermore, a control console for controlling the start and stop of the first motor and the second motor is provided on one side of the vertical plate.

[0011] Furthermore, a plurality of storage compartments are provided on the outer side of the vertical plate. The vertical plate is fixed to the ground by bolts, and the storage compartments can not only store various tools, but also reduce the weight of the vertical plate.

[0012] The five-axis head includes a swing head, a connecting flange and a reducer, and the connecting flange has a circle of connecting holes. The five-axis head passes through the limiting hole of the positioning plate, and the connecting flange abuts against the periphery of the limiting hole, and the connecting flange is fixed to the positioning plate by bolts. The five-axis head to be assembled is placed in the detection groove of the transfer frame together with the positioning plate, and the transfer frame is pushed toward the base along the linear guide rail. The transfer frame is finally transferred to the rotating disk along the guide slope, and the angle and position of the transfer frame are adjusted to align the groove with the clearance hole. Four lifting cylinders are installed in the groove, and the second motor is started to rotate the transfer frame 90°. Since the positioning plate is rectangular, the positioning plate will not contact the mounting plate during the rising process. The lifting cylinder is started to make the positioning plate higher than the mounting groove of the mounting plate, and the five-axis head is higher than the transfer frame. At this time, the transfer frame is withdrawn, and then rotated 90° back to its original position, and the lifting cylinder is driven to lower the positioning plate so that both ends of the positioning plate fall into the mounting groove. The positioning plate is fixed to the mounting plate by bolts passing through the first bolt hole, and the lifting cylinder is removed to make room. The next step is to install the internal parts of the five-axis head, assemble the reducer, gearbox and other parts to the five-axis head. During the transfer process, the first motor can be started to drive the angle adjustment disk to rotate, so that the five-axis head can be in a horizontal state, which is convenient for assembling parts. After all the assemblies are completed, unscrew the bolts, install the lifting cylinder and push the transfer frame back to the rotating disk, start the lifting cylinder, lift the positioning plate and the five-axis head, and then start the second motor to rotate the rotating disk 90°. After the positioning plate falls into the detection slot, the rotating disk rotates 90°, and the bolts are inserted into the third bolt hole to fix the positioning plate and the transfer frame together. The transfer frame is pushed onto the linear guide rail, and the transfer frame slides to the detection station to detect various parameters.

[0013] Compared with the prior art, this five-axis head production line special installation device has the following advantages:

[0014] 1. During assembly and inspection, the positioning plate is always fixed to the five-axis head. Ensuring that the positioning plate is in a horizontal state can keep the five-axis head in a vertical state, thereby improving installation accuracy and inspection accuracy.

[0015] 2. The height of the five-axis head is raised or lowered by the lifting cylinder, and the five-axis head is lifted vertically, so that the positioning plate is placed on the mounting plate or removed from the mounting plate. The five-axis head is not transferred by hanging it with a crane, which reduces the swing and collision during the transfer.

[0016] 3. The five-axis head is flipped by the first motor, and the tilt angle of the five-axis head is controllable, which saves effort and improves assembly efficiency.

[0017] 4. The five-axis head needs to be transferred from the assembly station to the inspection station. The five-axis head is protected by the transfer frame sliding along the linear guide rail. During the transfer, the positioning plate and the transfer frame are locked, the five-axis head will not shake, and the five-axis head is located inside the transfer frame, thus avoiding bumps.
