The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, for the utility model discloses a protective cover of numerical control machining center, including organism 1, guard gate 2 and be used for the bowl 3 of reflected noise. A processing cavity 11 for processing and a processing opening 12 communicated with the processing cavity 11 are formed in the machine body 1. Guard gate 2 is equipped with two and the symmetry locates on organism 1, and guard gate 2 locates the processing mouth 12 department of organism 1 and is used for sealing processing mouth 12, and guard gate 2 is along horizontal direction sliding connection in organism 1. The reflection cover 3 is arranged in the processing cavity 11 and is connected to the machine body 1 in a sliding manner.

When the machining is carried out in the machining cavity 11, the reflecting cover 3 slides to the position right above the machining position, the machining position and the machining opening 12 are separated, when noise generated by machining is transmitted towards the machining opening 12, the noise needs to pass through the reflecting cover 3, sound energy is weakened by the reflecting cover 3 when the noise passes through the reflecting cover 3, part of the noise is reflected continuously in the machining cavity 11 after being reflected by the reflecting cover 3, and when the noise is reflected to the machining opening 12, the noise passes through the protective door 2, the sound energy is further weakened, and therefore the noise is reduced and is transmitted out of the machine body 1.

Referring to fig. 2, the reflective cover 3 is made of hard plastic, and has a transparent and smooth surface. The reflector 3 is arranged along the length direction of the processing cavity 11 and has a semicircular section with an opening facing the processing position.

Referring to fig. 2, the machine body 1 is located on the inner wall of the processing cavity 11 and is provided with a sliding chute 13, and the sliding chute 13 is located at two ends of the reflection cover 3 and is provided with one. The cross section of the sliding chute 13 in the vertical direction is in the shape of an arc with a downward opening, and the central angle subtended by the arc of the sliding chute 13 is 90 degrees. The two ends of the reflection housing 3 are correspondingly provided with the sliding blocks 31, the sliding blocks 31 are positioned on one side of the reflection housing 3 close to the processing opening 12, and when the sliding blocks 31 abut against one end of the sliding chute 13 close to the processing opening 12, the reflection housing 3 is symmetrically positioned above the processing position.

The reflector 3 is provided with a sliding groove 13, and the sliding track of the reflector comprises a covering section and a receiving section. Through the setting of spout 13, make bowl 3 when the cover section with accomodate the section and switch between two sections, must receive external force, make slider 31 overcome gravity and cross spout 13 horizontal position highest point along spout 13, just can accomplish the switching, improved the stability of two states of bowl 3.

When the slide block 31 is in sliding contact with one end of the slide groove 13 close to the processing opening 12, the reflection cover 3 is located at the covering section, and the reflection cover 3 is covered above the processing position and separates the processing position from the processing opening 12. When the slide block 31 is in sliding contact with one end of the slide groove 13 far away from the processing opening 12, the reflection cover 3 is located at the storage section, and the reflection cover 3 is stored at one side of the processing cavity 11 far away from the processing opening 12.

One end of the sliding block 31, which is located in the sliding groove 13, is rotatably connected with a roller 32, the roller 32 is embedded and is connected to the sliding groove 13 in a rolling manner along the opening direction of the sliding groove 13, so that the friction resistance between the sliding block and the sliding groove 13 is reduced while the reflecting cover 3 is guided, and the sliding smoothness of the reflecting cover 3 is improved.

One side of bowl 3 towards processing mouth 12 is fixed and is equipped with bearing block 33, bearing block 33 is the T shape of opening towards bowl 3, the both ends fixed connection of bearing block 33T shape is in 3 periphery walls of bowl, make bowl 3 fix a position when the cover segment, the focus is partial to processing mouth 12 one side, improve bowl 3 in the stability of cover segment, set up bearing block 33 into T shape simultaneously, make bearing block 33 can regard as the handle to use, make things convenient for operating personnel pulling bowl 3.

Referring to fig. 3, a viewing port 21 is formed in the protective door 2, and a soundproof glass 211 is fixed to the viewing port 21. Guard gate 2 is equipped with sound absorbing layer 22 towards one side is fixed in the processing chamber 11, and sound absorbing layer 22 is for inhaling the sound cotton, and sound absorbing layer 22 passes through adhesive bonding in guard gate 2, sets up the mouth of dodging viewing aperture 21 on the sound absorbing layer 22, makes things convenient for operating personnel to observe the processing condition from viewing aperture 21, and sound absorbing layer 22 sets up the noise that makes through bowl 3 when passing through guard gate 2, and sound energy is absorbed by sound absorbing layer 22, further improves noise reduction.

The fixed sealing strip 4 that is equipped with in one side of another protective door 2 of protective door 2 orientation, sealing strip 4 all corresponds for each protective door 2 of rubber strip and is equipped with a sealing strip 4. When the protective door 2 is closed, the gap between the two protective doors 2 is sealed by the sealing strip 4, so that the sealing effect and the noise reduction effect are improved.

The implementation principle of the embodiment is as follows:

when a workpiece is machined in the machining cavity 11, the bearing block 33 sliding to the reflecting cover 3 of the containing section is held through the machining opening 12, a force is applied downwards, the reflecting cover 3 slides to the covering section through the guide of the sliding chute 13, the reflecting cover 3 is covered over the machining position and separates the machining position from the machining opening 12, when noise generated at the machining position is transmitted to the machining opening 12, the noise needs to pass through the reflecting cover 3, sound energy is weakened by the reflecting cover 3 when the noise passes through the reflecting cover 3, part of the noise is reflected by the reflecting cover 3 and then is reflected continuously in the machining cavity 11, when the noise is reflected to the machining opening 12, the noise passes through the protective door 2, the sound energy is further weakened by the sound insulation glass 211 and the sound absorption layer 22 on the protective door 2, and the noise is reduced to be transmitted out of the machine body 1.

When needs operate in the processing chamber 11, open guard gate 2, grip the ascending application of force of bearing block 33, slide the protection casing to the section of accomodating, make the protection casing accomodate in the one side that the processing position is kept away from processing mouth 12, make things convenient for operating personnel to carry out the processing operation from processing mouth 12.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
