Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

Example (b):

referring to fig. 1, the present embodiment provides a protection device for a circular sawing machine milling cutter 3, which includes a machine table 1, a cutter shaft 2 disposed on the machine table 1, and a milling cutter 3 mounted on the cutter shaft 2; when the milling machine works, the motor is not shown in the figure and drives the cutter shaft 2 to rotate, and the cutter shaft 2 drives the milling cutter 3 to rotate so as to finish the milling work.

The protection device also comprises a semicircular mounting plate 4 arranged on the machine table 1, wherein the milling cutter 3 is positioned in the middle of the inside of the mounting plate 4; a cylindrical protective cover 5 which covers the milling cutter 3 is detachably connected to the upper wall of the mounting plate 4, wherein a notch 51 for protruding the cutter face of the milling cutter 3 is formed in the side wall of one side of the protective cover 5; a vertically arranged fixed shaft 52 is fixedly connected to the center of the top wall of the shield 5; the outer circumferential wall of the shield 5 is slidably connected with a protective plate 6 which can slide along the circumferential wall of the shield 5 and is in an arc shape, wherein the top of the protective plate is fixedly connected with a fan-shaped plate 61, and the end part of the fan-shaped plate 61 is rotatably connected on the fixed shaft 52.

When the milling operation is needed, the fan-shaped plate 61 is rotated to enable the protection plate 6 to rotate to a position far away from the notch 51, at the moment, the cutter face of the milling cutter 3 is exposed out of the notch 51, and the normal milling operation can be performed by utilizing the cutter face protruding out of the notch 51; at this time, the other faces of the milling cutter 3 are all covered by the protective cover 5, so that the danger that the hands are cut by the other faces of the milling cutter 3 can be prevented.

When the milling cutter 3 does not need to be opened, the fan-shaped plate 61 is only required to be rotated to drive the protection plate 6 to cover the notch 51, so that the whole milling cutter 3 is completely enclosed in the protective cover 5, and even if someone opens the milling cutter 3 carelessly, the milling cutter 3 only rotates in the protective cover 5 and cannot cause injury to people.

Because milling cutter 3 is when milling the work piece, can produce more sweeps, some in these sweeps can be along with milling cutter 3 rotatory entering guard shield 5 in, operating time is longer, the sweeps of accumulation in guard shield 5 just can be more and more, when the sweeps of accumulation in guard shield 5 is too much, then can influence milling cutter 3's normal work, guard shield 5 is demountable installation on mounting panel 4 in this embodiment, so alright when guard shield 5 has accumulated the sweeps too much, dismantle guard shield 5 from mounting panel 4, can clear away the sweeps that accumulates in guard shield 5 and mounting panel 4 inboard after dismantling guard shield 5, after the clearance, install guard shield 5 again can, so just can prevent that the excessive sweeps of accumulation in guard shield 5 from influencing milling cutter 3's normal work.

In order to facilitate the detachment of the shield 5, as shown in fig. 2 and 3, a plurality of positioning columns 7 vertically arranged are fixedly connected to the upper wall of the mounting plate 4 at positions close to the inner side; a positioning hole 53 for inserting the positioning column 7 is formed on the lower wall of the protective cover 5 corresponding to the positioning column 7; the mounting plate 4 is provided with a plurality of locking assemblies 8 for locking the shield 5.

Wherein the locking assembly 8 is specifically: the locking assembly 8 comprises a fixed block 81 which is detachably arranged on the upper wall of the mounting plate 4, and a threaded through hole 811 is formed in the fixed block 81; the threaded through hole 811 is internally threaded with a threaded rod 82; the outer side wall of the shield 5 near the lower end is correspondingly provided with a jack 54 for inserting the inner end of the threaded rod 82.

When installing guard shield 5 like this, only need aim at locating column 7 on the mounting panel 4 with the locating hole 53 of guard shield 5 lower part, insert locating column 7 with guard shield 5 again can, jack 54 on the lower part lateral wall of guard shield 5 this moment just right to the inner of threaded rod 82, and then only need manually rotate threaded rod 82 and make threaded rod 82 move towards jack 54 one side, until the inner of threaded rod 82 insert in jack 54 can, accomplish the installation of guard shield 5, so under the restriction of threaded rod 82 and locating column 7, the skew just can't take place for guard shield 5, accomplish the installation of guard shield 5. When the shield 5 is removed, the shield 5 can be withdrawn from the mounting plate 4 by rotating the threaded rod 82 in the opposite direction to disengage the inner end of the threaded rod 82 from the receptacle 54. It follows that the removal or mounting of the shield 5 can be completed without the aid of any tools during this process. The positioning hole 53 has two functions: one is to prevent the shield 5 from shifting horizontally, but to position the shield 5 to ensure that the receptacle 54 faces the threaded rod 82 during installation, thereby increasing the installation speed.

In order to facilitate the rotation of the threaded rod 82, a hand wheel 83 may be fixedly attached to an outer end portion of the threaded rod 82.

Because the whole circular sawing machine works, the surface of the machine table 1 can generate larger vibration, so that parts on the protective device can be loosened, a layer of buffer cushion 41 is bonded on the lower wall of the mounting plate 4, and the specific buffer cushion 41 can be a rubber cushion; mounting panel 4 and buffer 41 pass through first screw 42 and install on board 1, so buffer 41 just can play certain shock attenuation cushioning effect, reduces the not hard up problem of part on the protector.

Both sides of the fixed block 81 are provided with protrusions 812 extending outward; wherein the protrusion 812 is mounted on the upper wall of the mounting plate 4 by means of a second screw 813. When the threaded rod 82 has the problem of tooth slippage, the whole fixed block 81 can be taken down and replaced by screwing down the second screw 813.

A pulling lug 62 is fixedly connected to the upper wall of the sector plate 61. The provision of the trigger 62 may serve to provide a point of application to facilitate rotation of the sector plate 61.

The above is only the typical example of the utility model, in addition, the utility model can also have other multiple concrete implementation manners, and the technical scheme that all adopt equivalent replacement or equivalent transform to form all falls within the scope of the utility model.
