Description

Technical Field

[0001] This utility model relates to the field of milling machine technology, specifically to a milling cutter height adjustment device for a milling machine. Background Technology

[0002] A milling machine is a machine tool that uses a milling cutter to machine various surfaces of a workpiece. The main motion is the rotation of the milling cutter, 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 mainly composed of a series of components such as milling cutters, fixtures, and adjustment devices. Current adjustment devices primarily adjust the height of the milling cutter. These devices are mainly driven by a motor that rotates a threaded rod, allowing the milling cutter to slide on the surface of the rod. However, most adjustment devices lack a sealing structure, making it difficult to protect the area where the milling cutter moves. Over time, dust from the air easily adheres to the surface of the threaded rod, reducing its lifespan. Utility Model Content

[0003] The purpose of this invention is to provide a milling cutter height adjustment device for a milling machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a milling cutter height adjustment device for a milling machine, comprising a base plate, a vertical plate fixedly connected to one side of the base plate, a movable plate slidably connected to the outside of the vertical plate, an auxiliary block connected to one side of the movable plate, a milling cutter rotatably connected inside the auxiliary block, a driver fixedly connected above the auxiliary block, a motor fixedly connected above the vertical plate, a sealing structure connected to the side of the vertical plate, the sealing structure being connected to the movable plate, a snap-fit ​​structure being provided inside the sealing structure, a threaded rod rotatably connected inside the vertical plate, the sealing structure comprising a sealing plate, a concave plate, a first limiting block, and a second limiting block, two first baffles slidably connected inside the concave plate, a third baffle slidably connected inside the second limiting block, and a second baffle slidably connected inside the first limiting block.

[0005] As a further preferred embodiment of this technical solution, the output shaft of the motor is connected to the threaded rod, and the movable plate is threadedly connected to the outside of the threaded rod.

[0006] As a further preferred embodiment of this technical solution, the concave plate is fixedly connected to the lower side of the upright plate, the first limiting block is fixedly connected to the upper side of the upright plate, the second limiting block is fixedly connected to the upper side of the upright plate, and there is a gap between the first limiting block and the second limiting block.

[0007] As a further preferred embodiment of this technical solution, the third baffle is fixedly connected above the movable plate, the second baffle is fixedly connected above the movable plate, and the two first baffles are fixedly connected below the movable plate.

[0008] As a further preferred embodiment of this technical solution, the sealing plate is snapped into the movable plate, and the sealing plate overlaps the concave plate.

[0009] As a further preferred embodiment of this technical solution, the snap-fit ​​structure includes a guide rod and a bolt. The guide rod is rotatably connected within the second limiting block, and a rotating plate is connected to the outside of the guide rod. The bolt is fixedly connected within the first limiting block.

[0010] As a further preferred embodiment of this technical solution, the rotating plate has a groove inside, the rotating plate is snapped into the sealing plate, the rotating plate is snapped into the limiting block, the bolt is externally threaded to a clamping plate, and the clamping plate overlaps with the rotating plate.

[0011] This utility model provides a milling cutter height adjustment device for a milling machine, which has the following beneficial effects:

[0012] (1) This utility model, by setting a moving plate, a sealing structure, a motor and a threaded rod, adjusts the height of the milling cutter in the auxiliary block by driving the threaded rod to rotate through the motor, while the moving plate slides on the surface of the threaded rod. The moving plate then drives the second baffle to slide within the first limiting block, and the third baffle to slide within the second limiting block. The first baffle slides within the concave plate. By adjusting the positions of the first, second and third baffles, a sealed space can be formed with the sealing plate. Through the cooperation between the first, second and third baffles, the sealing structure can play a certain sealing role on the moving moving plate, preventing dust in the air from entering the vertical plate through the movement of the moving plate, preventing dust from contaminating the surface of the threaded rod, thus ensuring the service life of the threaded rod and improving the flexibility of the adjustment device.

[0013] (2) By setting a snap-fit ​​structure, the sealing plate overlaps the concave plate, and the sealing plate will intersect with the moving plate. The sealing plate will be on the same horizontal line as the first and second limit blocks, which will drive the rotating plate to rotate around the guide rod. When the rotating plate rotates, the groove will intersect with the bolt and the snap-fit ​​plate. When the rotating plate is attached to the first limit block, it will drive the snap-fit ​​plate to rotate. After the snap-fit ​​plate rotates on the surface of the bolt, it will overlap with the rotating plate and form a cross shape, so that the sealing plate and the upright plate can achieve the function of quick assembly. It is convenient to replace or repair the upright plate later, and the threaded rod inside the upright plate can be lubricated and maintained. Attached Figure Description

[0019] 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.

[0020] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown in this embodiment, a milling cutter height adjustment device for a milling machine includes a base plate 1, a vertical plate 2 fixedly connected to one side of the base plate 1, a movable plate 3 slidably connected to the outside of the vertical plate 2, an auxiliary block 4 connected to one side of the movable plate 3, a milling cutter 5 rotatably connected inside the auxiliary block 4, a driver 6 fixedly connected above the auxiliary block 4, a motor 9 fixedly connected above the vertical plate 2, a sealing structure 7 connected to the side of the vertical plate 2, the sealing structure 7 being connected to the movable plate 3, a snap-fit ​​structure 8 provided inside the sealing structure 7, a threaded rod 10 rotatably connected inside the vertical plate 2, and the sealing structure 7 including a sealing plate 701, a concave plate 702, a first limiting block 705, and a second limiting block 706. Two first baffles 703 are slidably connected inside the concave plate 702, a third baffle 707 is slidably connected inside the second limiting block 706, and a second baffle 704 is slidably connected inside the first limiting block 705.

[0021] like Figure 1 and Figure 3As shown, the output shaft of motor 9 is connected to threaded rod 10, movable plate 3 is threaded to the outside of threaded rod 10, concave plate 702 is fixedly connected to the lower side of vertical plate 2, limit block 1 705 is fixedly connected to the upper side of vertical plate 2, limit block 2 706 is fixedly connected to the upper side of vertical plate 2, there is a gap between limit block 1 705 and limit block 2 706, baffle 3 707 is fixedly connected to the upper side of movable plate 3, baffle 2 704 is fixedly connected to the upper side of movable plate 3, two baffles 1 703 are fixedly connected to the lower side of movable plate 3, sealing plate 701 is snapped into movable plate 3, and sealing plate 701 overlaps in concave plate 702.

[0022] By setting baffle 1 703, baffle 2 704 and baffle 3 707, motor 9 drives threaded rod 10 to rotate, and moving plate 3 will slide on its surface. Baffle 2 704 will slide within limit block 1 705, baffle 3 707 will slide within limit block 2 706, and baffle 1 703 will slide within concave plate 702. By adjusting the positions of baffle 1 703, baffle 2 704 and limit block 2 706, a sealed space can be formed with sealing plate 701 to avoid gaps when moving plate 3, and to provide a certain degree of protection for the moving area of ​​moving plate 3.

[0023] like Figure 4 As shown, the snap-fit ​​structure 8 includes a guide rod 801 and a bolt 803. The guide rod 801 is rotatably connected to the second limiting block 706. A rotating plate 802 is connected to the outside of the guide rod 801. The bolt 803 is fixedly connected to the first limiting block 705. A groove 805 is provided in the rotating plate 802.

The clamping plate 804 overlaps with the rotating plate 802.

[0024] By setting the snap-fit ​​structure 8, the sealing plate 701 is overlapped above the concave plate 702, and the sealing plate 701 will intersect with the moving plate 3. The sealing plate 701 will be on the same horizontal line as the first limiting block 705 and the second limiting block 706, which will drive the rotating plate 802 to rotate around the guide rod 801. When the rotating plate 802 rotates, the groove 805 will intersect with the bolt 803 and the clamping plate 804. When the rotating plate 802 is in contact with the first limiting block 705, it will drive the clamping plate 804 to rotate. After the clamping plate 804 rotates on the surface of the bolt 803, it will overlap with the rotating plate 802 and form a cross shape, so that the sealing plate 701 and the upright plate 2 can be quickly assembled. This facilitates the replacement or maintenance of the upright plate 2 and allows for the lubrication and maintenance of the threaded rod 10 inside the upright plate 2.

[0025] This utility model provides a milling cutter height adjustment device for a milling machine, the specific working principle of which is as follows:

[0026] When the adjusting device is in use, the sealing plate 701 can be overlapped above the concave plate 702, and the sealing plate 701 will intersect with the moving plate 3. The sealing plate 701 will be on the same horizontal line as the first limiting block 705 and the second limiting block 706, causing the rotating plate 802 to rotate around the guide rod 801. When the rotating plate 802 rotates, the groove 805 will intersect with the bolt 803 and the clamping plate 804. When the rotating plate 802 is in contact with the first limiting block 705, it will drive the clamping plate 804 to rotate. After the clamping plate 804 rotates on the surface of the bolt 803, it will overlap with the rotating plate 802 and form a cross shape.

[0027] When the adjusting device adjusts the height of the milling cutter 5 in the auxiliary block 4, the motor 9 drives the threaded rod 10 to rotate, and the moving plate 3 slides on the surface of the threaded rod 10. The moving plate 3 then drives the second baffle 704 to slide in the first limiting block 705, the third baffle 707 to slide in the second limiting block 706, and the first baffle 703 to slide in the concave plate 702. By adjusting the positions of the first baffle 703, the second baffle 704 and the second limiting block 706, a sealing space can be formed with the sealing plate 701.
