Description

Technical Field

[0001] This utility model relates to the field of milling machine equipment technology, and in particular to a small milling machine with protective function. Background Technology

[0002] A milling machine is a machine tool that uses a milling cutter to machine various surfaces of a workpiece. Typically, the milling cutter's rotation is the primary motion, while the movement of the workpiece and the cutter constitutes the feed motion. It can machine planes, grooves, various curved surfaces, gears, etc. A milling machine is a machine tool that uses a milling cutter to perform milling operations on a workpiece. Besides milling planes, grooves, gear teeth, threads, and splined shafts, milling machines can also machine relatively complex profiles. They are more efficient than planers and are widely used in mechanical manufacturing and repair departments. Milling machines are versatile machine tools that can machine planes (horizontal and vertical), grooves (keyways, T-slots, dovetail grooves, etc.), geared parts (gears, splined shafts, sprockets), helical surfaces (threads, helical grooves), and various curved surfaces. During milling, high-speed cutting generates metal or non-metal chips that fly everywhere, potentially injuring operators and damaging surrounding equipment. Furthermore, if the fine dust generated during processing is not effectively controlled, it can be inhaled by operators, and long-term exposure may lead to respiratory diseases or even pneumoconiosis. Existing small milling machines often lack reliable chip protection and dust collection devices, making it difficult to meet occupational health and safety requirements. Furthermore, the protective structures on existing machine tools cannot be adjusted in position to accommodate the shape and size of the workpiece being machined. Therefore, there is a need for a small milling machine with protective functions. Utility Model Content

[0003] The purpose of this invention is to provide a small milling machine with protective functions to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A small milling machine with protective function includes a base and a milling machine body. The milling machine body is mounted on the base and has a first horizontally movable end and a second vertically movable end. The second movable end is mounted on the first movable end and has a milling head. The base has a side-pressure fixing mechanism and a magnetic pole plate. The base has a mounting frame, and the magnetic pole plate is horizontally mounted in the mounting frame. The side-pressure fixing mechanism is slidably engaged with the base. The mounting frame has a protective mechanism and a protective adjustment mechanism that drives the protective mechanism to adjust.

[0006] A further technical solution is provided, wherein the side pressure fixing mechanism includes a side pressure cylinder, a side pressure plate, two slide rods and two support seats. The side pressure cylinder is horizontally mounted on the base, the two support seats are symmetrically mounted on the side wall of the base, the two slide rods are horizontally mounted on the two support seats respectively, and the two ends of the side pressure plate are slidably connected to the two slide rods and the side pressure plate is connected to the telescopic end of the side pressure cylinder.

[0007] A further technical solution is that the top of the side pressure plate is provided with a movable slide module, and the movable slide module is provided with a side pressure fixing plate.

[0008] A further technical solution is provided, wherein the protective mechanism includes a left protective cover, a right protective cover and two slide rails, the two slide rails are respectively mounted on the mounting frame and the side pressure plate, the left protective cover and the right protective cover are slidably connected to the two slide rails respectively, and a left and right corrugated protective pad is provided between the left protective cover and the right protective cover.

[0009] In a further technical solution, the left and right protective covers have the same structure. The left protective cover includes a large protective cover, a small protective cover, and a connecting corrugated protective pad. The large and small protective covers are slidably engaged with two slide rails respectively. The small protective cover is provided with a limiting rod that slidably engages with the large protective cover. The connecting corrugated protective pad is located between the large and small protective covers. The large protective cover is provided with a moving groove for the milling head to move.

[0010] A further technical solution includes a protective adjustment mechanism comprising a support frame, an adjustment motor, a bidirectional adjustment screw, and two adjustment blocks. The support frame is horizontally mounted on the side wall of the base. The bidirectional adjustment screw is rotatably connected to the support frame. The adjustment motor is located on the side wall of the support frame and is drivenly connected to the bidirectional adjustment screw. The two adjustment blocks are threadedly connected to the two bidirectional adjustment screws and slidably engaged with the support frame. The two adjustment blocks are respectively connected to the left protective cover and the right protective cover.

[0011] In a further technical solution, a chip conveyor is provided on the base, and two dust suction fans are provided on both the left and right protective covers, with the dust suction fans connected to the chip conveyor.

[0012] The beneficial effects of this utility model are:

[0013] When the position of the protective mechanism needs to be adjusted, the adjusting motor is energized, driving the adjusting bidirectional lead screw to rotate. Since the two adjusting blocks are threaded onto different threaded sections of the adjusting bidirectional lead screw, when the lead screw rotates, the two adjusting blocks move towards or away from each other along the screw axis, thereby causing the left and right protective covers connected to them to move synchronously. This achieves precise adjustment of the protective mechanism's position, enabling quick and accurate adjustment to suit the processing needs of workpieces of different shapes and sizes, greatly improving the applicability and flexibility of the protective mechanism. The automated adjustment method reduces manual operation, improves production efficiency, and avoids protective loopholes caused by inaccurate manual adjustments, further enhancing the safety of small milling machines.

[0014] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please refer to Figure 1-6 As shown; this utility model provides a technical solution for a small milling machine with protective function: a small milling machine with protective function includes a base 1 and a milling machine body 2. The milling machine body 2 is mounted on the base 1. The milling machine body 2 is provided with a first moving end 21 that moves horizontally and a second moving end 22 that moves vertically. The second moving end 22 is mounted on the first moving end 21 and is provided with a milling head 23. The base 1 is provided with a side pressure fixing mechanism 3 and a magnetic pole plate 8. The base 1 is provided with a mounting frame 11. The magnetic pole plate 8 is horizontally mounted in the mounting frame 11. The side pressure fixing mechanism 3 is slidably engaged with the base 1. The mounting frame 11 is provided with a protective mechanism 4 and a protective adjustment mechanism 5 that drives the protective mechanism 4 to adjust.

[0024] Before processing, the side-pressure fixing mechanism 3 firmly clamps the workpiece, and the magnetic pole plate 8 is energized and adsorbed onto the steel worktable or workpiece surface to ensure the stability of the milling machine. During processing, the protective adjustment mechanism 5 drives the protective mechanism 4 to adjust the protective position according to the shape and size of the workpiece. At the same time, the dust extraction fan 7 works with the chip conveyor 6 to collect chips and dust, ensuring processing safety and environmental cleanliness.

[0025] The magnetic pole plate 8 operates on the principle of magnetic attraction. When the milling machine needs to be fixed to the surface of a steel workpiece for machining, energizing the magnetic pole plate 8 causes the internal electromagnetic coil to generate an electromagnetic effect, which in turn produces a strong magnetic attraction force. This magnetic attraction force causes the magnetic pole plate 8 to adhere to the workpiece surface, acting like an "electromagnetic hand" that firmly grips the workpiece, ensuring the milling machine remains stable and does not wobble during machining. This counteracts the vibrations and cutting forces generated during milling, providing a stable foundation for precise machining. After machining is completed, disconnecting the power to the magnetic pole plate 8 causes the electromagnetic effect to disappear, and the magnetic attraction force to vanish, facilitating the movement and repositioning of the milling machine.

[0026] In this embodiment, refer to Figure 3 and Figure 5 As shown, the side pressure fixing mechanism 3 includes a side pressure cylinder 31, a side pressure plate 32, two slide rods 33, and two support seats 34. The side pressure cylinder 31 is horizontally arranged on the base 1, and the two support seats 34 are symmetrically arranged on the side wall of the base 1. The two slide rods 33 are respectively horizontally arranged on the two support seats 34. The two ends of the side pressure plate 32 are slidably connected to the two slide rods 33, and the side pressure plate 32 is connected to the telescopic end of the side pressure cylinder 31. The top of the side pressure plate 32 is provided with a movable slide module 35, and the movable slide module 35 is provided with a side pressure fixing plate 36.

[0027] The movable slide module 35 can move the position of the side pressure fixing plate 36 along the length of the magnetic pole plate 8, and fix the workpiece placed on the magnetic pole plate 8 at different positions. When fixing, the side pressure cylinder 31 is energized and its telescopic end pushes the side pressure plate 32. Under the guidance of the slide rod 33, the side pressure plate 32 moves horizontally along the slide rod 33, thereby driving the side pressure fixing plate 36 to be side-pressed and fixed, preventing the material from flying away and causing accidents during processing.

[0028] In this embodiment, refer to Figure 3 , Figure 4 and Figure 5 As shown, the protective mechanism 4 includes a left protective cover 40, a right protective cover 41, and two slide rails 42. The two slide rails 42 are respectively mounted on the mounting frame 11 and the side pressure plate 32. The left protective cover 40 and the right protective cover 41 are slidably connected to the two slide rails 42, and left and right corrugated protective pads 43 are provided between the left protective cover 40 and the right protective cover 41. The protective mechanism 4 can flexibly adjust the protection range according to the shape and size of the workpiece, providing effective protection for both small precision parts and larger workpieces, preventing chip splashing and dust diffusion.

[0029] In this embodiment, the protective adjustment mechanism 5 includes a support frame 51, an adjustment motor 52, an adjustment bidirectional lead screw 53, and two adjustment blocks 54. The support frame 51 is horizontally disposed on the side wall of the base 1. The adjustment bidirectional lead screw 53 is rotatably connected to the support frame 51. The adjustment motor 52 is located on the side wall of the support frame 51 and is drivenly connected to the adjustment bidirectional lead screw 53. The two adjustment blocks 54 are respectively threaded to the two adjustment bidirectional lead screws 53 and slide in cooperation with the support frame 51. The two adjustment blocks 54 are respectively connected to the left protective cover 40 and the right protective cover 41.

[0030] When the position of the protective mechanism 4 needs to be adjusted, the adjusting motor 52 is energized, driving the adjusting bidirectional lead screw 53 to rotate. Since the two adjusting blocks 54 are threaded onto different threaded sections of the adjusting bidirectional lead screw 53, when the adjusting bidirectional lead screw 53 rotates, the two adjusting blocks 54 move towards or away from each other along the lead screw axis, thereby driving the left protective cover 40 and right protective cover 41, which are connected to it respectively, to move synchronously. This achieves precise adjustment of the position of the protective mechanism 4, enabling quick and accurate adjustment to suit the processing needs of workpieces of different shapes and sizes, greatly improving the applicability and flexibility of the protective mechanism 4. The automated adjustment method reduces manual operation, improves production efficiency, and also avoids protective loopholes caused by inaccurate manual adjustments, further enhancing the safety of the small milling machine.

[0031] In this embodiment, refer to Figure 6As shown, the left protective cover 40 and the right protective cover 41 have the same structure. The left protective cover 40 includes a large protective cover 44, a small protective cover 45 and a connecting corrugated protective pad 46. The large protective cover 44 and the small protective cover 45 are respectively slidably engaged with two slide rails 42. The small protective cover 45 is provided with a limiting rod 47 that is slidably engaged with the large protective cover 44. The connecting corrugated protective pad 46 is located between the large protective cover 44 and the small protective cover 45. The large protective cover 44 is provided with a moving groove 48 for the milling head 23 to move.

[0032] When the workpiece is side-pressed and fixed, the small protective cover 45 will move on the large protective cover 44 through the limiting rod 47, thereby moving the position of the small protective cover 45. The corrugated protective pad 46 can protect the space between the large protective cover 44 and the small protective cover 45.

[0033] The retractable protective cover design of the left and right corrugated protective pads 43 and the connecting corrugated protective pad 46 ensures both airtight protection and does not affect the normal operation of the milling machine, thus balancing safety and ease of operation.

[0034] In this embodiment, refer to Figure 4 As shown, a chip conveyor 6 is provided on the base 1, and two dust suction fans 7 are provided on both the left protective cover 40 and the right protective cover 41. The dust suction fans 7 are connected to the chip conveyor 6.

[0035] When the first moving end 21 and the second moving end 22 on the milling machine body 2 work to drive the milling head 23, the waste chips generated can be absorbed by the dust extraction fan 7 and put into the chip conveyor 6, and the waste chips are discharged by the chip conveyor 6.
