Description

Technical Field

[0001] This utility model relates to the field of chip removal technology for machining centers, and specifically to a chip removal mechanism for machining centers that prevents chip accumulation. Background Technology

[0002] A machining center is a comprehensive machining operation device that can perform various operations, such as turning, milling, tapping, and drilling. During operation, a large amount of waste chips will accumulate on the table. The accumulation of waste chips and iron filings can affect the operation and the tool head. In severe cases, it may even cause the tool head to break. Therefore, it is necessary to clean the waste chips in a timely manner.

[0003] The existing chip removal operation in machining centers requires external equipment, which is cumbersome to install inside the machining center. For example, Chinese Patent Publication No. CN220312671U discloses a chip removal mechanism for a gantry machining center, which includes a gantry mechanism and a chip removal mechanism; it also includes a tool changing mechanism, a cleaning mechanism, and a support mechanism. The chip removal mechanism is installed on the gantry mechanism, the tool changing mechanism is installed on the upper end of the gantry mechanism, the cleaning mechanism is installed on the upper end of the gantry mechanism, and the support mechanism is installed on the upper end of the gantry mechanism. The gantry mechanism processes the workpiece, the chip removal mechanism discharges the processed iron chips, the tool changing mechanism changes the tool in the gantry mechanism, the cleaning mechanism cleans the iron chips on the support mechanism, and the support mechanism moves the workpiece to a suitable position and fixes it. By setting up the chip removal mechanism and the cleaning mechanism, it can separate iron chips and moisture while better cleaning the iron chips on the worktable, thereby reducing the waste of manpower and improving work efficiency. However, its chip removal mechanism cannot accurately collect and transport waste chips from the worktable.

[0004] Therefore, it is necessary to invent a chip removal mechanism for machining centers that prevents chip accumulation in order to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a chip removal mechanism for machining centers that prevents chip accumulation, thereby solving the problem in the technology where waste chips accumulate on the operating table of machining centers, making it impossible to accurately handle the waste chips inside the operating table.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A chip removal mechanism for a machining center to prevent chip accumulation includes a machining center body, a milling mechanism, a base, an operating table, and a chip collection bin. The milling mechanism is mounted on the machining center body, and the base is located directly below the milling mechanism. An annular positioning seat is fixedly connected to the base, and multiple laterally movable clamps are provided on the outer edge of the positioning seat. The operating table is located at the center of the inner circle of the positioning seat. A chip collection bin is provided on the upper part of the base, and a baffle is slidably connected to the opening of the chip collection bin through a slide groove. Chip removal bins are fixedly installed at both ends of the base, and inclined platforms are provided inside the chip removal bins. The surface of the inclined platforms is coated with a lubricating coating.

[0008] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0009] 1. This utility model has two chip collection bins on the base, which can collect waste chips. When it is not necessary to collect waste chips, the baffle can be slid to the position where it overlaps with the bottom of the operating table, covering the part of the chip collection bin that overlaps with the operating table and keeping the entire table surface neat.

[0010] 2. This utility model utilizes a motor and a lever installed at the bottom of the operating platform. The continuously rotating lever moves the waste chips that do not fall directly into the chip collection bin from the bottom of the operating platform into the chip collection bin. The chips are then continuously transported to the chip discharge bin by the auger plate and then transported outside the chip discharge bin. Attached Figure Description

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] This utility model provides, for example Figures 1-3 The chip removal mechanism for a machining center, which prevents chip accumulation, includes a machining center body 1, a milling mechanism 2, a base 3, an operating table 6, and a chip collection bin 7. The milling mechanism 2 is mounted on the machining center body 1, and the base 3 is located directly below the milling mechanism 2. An annular positioning seat 4 is fixedly connected to the base 3. Multiple clamps 5 that can move laterally relative to the base 3 are provided on the outer edge of the positioning seat 4. The movement of the clamps 5 can be achieved by a screw drive. The operating table 6 is located at the center of the inner circle of the positioning seat 4. A chip collection bin 7 is provided on the upper part of the base 3. A baffle 8 is slidably connected to the opening of the chip collection bin 7 through a slide groove 701. Chip removal bins 9 are fixedly installed at both ends of the base 3. An inclined platform 10 is provided in the chip removal bin 9. The surface of the inclined platform 10 is coated with a lubricating coating. A motor 11 is placed in the chip removal bin 9 through a fixed plate. A auger plate 12 is connected to the motor 11 and extends into the chip collection bin 7.

[0021] Waste chips are collected using two chip collection bins 7 located inside the base 3, and the waste chips are transported out of the inclined platform 10 using a continuously rotating auger plate 12.

[0022] The operating platform 6 is equipped with a second motor 14 that drives the operating platform 6 to rotate relative to the base 3. In actual installation, the second motor 14 can be vertically installed in the base 3 to drive the operating platform 6 to rotate. The transmission shaft on the second motor 14 is connected to a lever 13, which can rotate with the motor shaft. The rotation range of the lever 13 is within the bottom of the positioning seat 4. The operating platform 6 is cylindrical, and there is a gap between the operating platform 6 and the positioning seat 4 in the radial direction. This gap part falls into the chip collection bin 7. The chip collection bin 7 is elongated, and its size matches the size of the auger plate 12. The length of the auger plate 12 is slightly smaller than the length of the chip collection bin 7. There are two chip collection bins 7 symmetrically arranged about the center of the operating platform 6, and each chip collection bin 7 is equipped with an auger plate 12.

[0023] Some of the debris falling from the bottom of the control panel 6 will fall directly into the chip collection bin 7, while some will not fall into the chip collection bin 7. In such cases, the continuously rotating lever 13 is needed to move the debris into the chip collection bin 7.

[0024] The surface of the actuating rod 13 is evenly provided with brushes. When the actuating rod 13 rotates, it is in close contact with the bottom surface of the positioning seat 4 and is in contact with the opening end of the chip collection bin 7 when rotating.

[0025] By using the continuously rotating lever 13, the waste chips are rotated and moved into the chip collection bin 7, and then transported to the outside of the chip discharge bin 9 by the auger plate 12.

[0026] Working principle of this utility model:

[0027] Refer to the instruction manual appendix Figures 1-3 When using this utility model, the workpiece to be milled is first placed in the positioning seat 4 and clamped and fixed by the clamps 5 on both sides. The milling head on the milling mechanism 2 will operate with the center of the operating table 6 as the center to mill the surface and other parts of the workpiece. The waste chips after the operation will fall into the inner circle of the positioning seat 4.

[0028] Refer to the instruction manual appendix Figures 3-6 By starting the motor 14 to drive the rotation of the lever 13, the waste collected at the bottom of the positioning seat 4 is continuously moved into the chip collection bins 7 on both sides (when it is not necessary to collect waste, the baffle 8 can be slid to the bottom of the positioning seat 4 to cover the part of the chip collection bin 7 that overlaps with the positioning seat 4).

[0029] After the waste chips are continuously moved into the chip collection bins 7 on both sides, the auger plate 12 is rotated by the operation of the motor 11, which continuously discharges the waste chips from the chip collection bins 7 into the chip discharge bins 9, and conveys them downward along the inclined platform 10, ensuring that there is no waste chip accumulation in the operating area of ​​the positioning seat 4.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
