DETAILED DESCRIPTION

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0025] Referring to Figure 1 - Figure 6 The utility model provides a technical scheme:

[0026] Embodiment one:

[0028] Transmission mechanism includes the motor 7 of fixed mounting in one side of machine body 2, the output end of motor 7 is fixedly connected with lead screw 8, the surface transmission of lead screw 8 is connected with moving block 9, one side of moving block 9 is fixedly connected with two transmission rods 10, one end of transmission rod 10 penetrates to the inside of machine body 2, and is fixedly connected with transmission frame 11, one side of transmission frame 11 is fixedly connected with one side of cleaning ring 5, the other side of transmission frame 11 is provided with jet mechanism.

[0029] In the embodiment, considering that the numerical control engraving and milling machine is used for a long time, the surface of the guide rail 4 will accumulate debris, which will cause the workbench to be not smooth in transmission. The existing cleaning method is generally to clean bit by bit by using an air gun manually, which is low in work efficiency, thereby reducing the practicability of the machine body 2 casting assembly. Therefore, by setting the transmission mechanism, when the surface of the guide rail 4 accumulates debris, the motor 7 is started to drive the lead screw 8 to rotate. While the lead screw 8 rotates, the moving block 9 is driven to move back and forth along the trajectory of the guide rod 23 and the guide hole 24. The moving block 9 drives the transmission rod 10, the transmission frame 11, and the cleaning ring 5 to move back and forth. While the cleaning ring 5 moves back and forth, the cleaning block 6 removes the debris on the surface of the guide rail 4, thereby improving the transmission of the workbench.

[0030] The problem of reducing the practicability of the machine body 2 casting assembly due to the accumulation of debris on the surface of the guide rail 4, which causes the workbench to be not smooth in transmission, is solved.

[0031] One side of the machine body 2 is fixedly connected with two guide rods 23, and one side of the moving block 9 is provided with a guide hole 24 for cooperating with the guide rods 23.

[0032] In the embodiment, by setting the guide rod 23 and the guide hole 24, when the lead screw 8 rotates to drive the moving block 9, the moving block 9 and other structures are limited to move back and forth along the trajectory of the guide rod 23 and the guide hole 24, which limits the moving trajectory and improves the stability during the moving process.

[0033] Preferably, the material of the cleaning block 6 is cotton fiber.

[0034] In this embodiment, by setting the material of the cleaning block 6 as cotton fiber, the cleaning block 6 can conveniently remove the debris on the guide rail 4 without causing wear to the surface of the guide rail 4.

[0035] Embodiment two:

[0036] On the basis of embodiment one, in this embodiment, the transmission mechanism is considered to move the cleaning block 6 to clean the guide rail 4, but it is considered that some small debris is difficult to remove by the cleaning block 6. Therefore, the air injection mechanism is provided, which comprises a gas collecting box 12 fixedly connected to one side of a transmission frame 11, one side of the gas collecting box 12 is fixedly communicated with an air inlet pipe 13 through a first one-way valve, the top of the gas collecting box 12 is fixedly communicated with a transmission pipe 14 through a second one-way valve, one end of the transmission pipe 14 is fixedly connected with a compression box 15, one side of the compression box 15 is fixedly communicated with two air injection pipes 16 through a one-way pressure valve, the inside of the gas collecting box 12 is provided with a push block 17, the bottom of the push block 17 is fixedly connected with a push rod 18, the bottom of the push rod 18 penetrates to the bottom of the gas collecting box 12, and is fixedly connected with a first extrusion block 19, the inner wall of the machine body 2 is fixedly connected with a second extrusion block 20 used in cooperation with the first extrusion block 19.

[0037] In this embodiment, the transmission mechanism is considered to move the cleaning block 6 to clean the guide rail 4, but it is considered that some small debris is difficult to remove by the cleaning block 6. Therefore, the air injection mechanism is provided, which can move the gas collecting box 12, the first extrusion block 19 and other structures while the transmission frame 11 moves. When the inclined part of the first extrusion block 19 contacts the surface of the second extrusion block 20, the first extrusion block 19, the push rod 18, the push block 17 and the piston 22 are moved upward due to the extrusion, so as to extrude the air in the gas collecting box 12, so that the gas enters the inside of the compression box 15 through the transmission pipe 14. When the first extrusion block 19 moves to not contact the second extrusion block 20, the elastic force of the spring 21 pushes the first extrusion block 19, the push rod 18, the push block 17 and the piston 22 to move downward. At this time, the gas collecting box 12 is under negative pressure, so that the gas enters the inside of the gas collecting box 12 through the air inlet pipe 13, and the cycle is repeated in sequence, so as to intermittently compress the gas in the compression box 15. When the gas in the compression box 15 reaches the limit of the one-way pressure valve, the gas is intermittently injected to the surface of the slide rail through the air injection pipe 16, so as to remove the small debris.

[0038] The problem that the transmission mechanism moves the cleaning block 6 to clean the guide rail 4, but some small debris is difficult to remove by the cleaning block 6 is solved.

[0040] The bottom of the first extrusion block 19 is fixedly connected with a spring 21, and the top of the spring 21 is fixedly connected with the bottom of the gas collecting box 12.

[0041] In the embodiment, when the first extrusion block 19 is not in contact with the second extrusion block 20, the first extrusion block 19 and other structures are pushed downward by the elastic force generated by the spring 21, thereby playing a resetting role.

[0042] The two sides of the first extrusion block 19 are in a slope shape, and the number of the second extrusion blocks 20 is several.

[0043] In the embodiment, when the slope part of the first extrusion block 19 is in contact with the surface of the second extrusion block 20, the first extrusion block 19, the pushing rod 18, the pushing block 17 and the piston 22 are driven to move upward under the influence of extrusion, thereby playing a transmission role, and the plurality of second extrusion blocks 20 can compress the gas in the gas collecting box 12 once every time the first extrusion block 19 and the second extrusion block 20 are in contact, thereby enabling the air jet pipe 16 to intermittently jet air.

[0044] The top of the pushing block 17 is fixedly connected with the piston 22, and the material of the piston 22 is rubber.

[0045] In the embodiment, the piston 22 is arranged to form a sealed cavity inside the gas collecting box 12, and the gas collecting and exhausting are performed when the piston 22 moves up and down.

[0046] Working principle: when the surface of the guide rail 4 is stacked with waste chips, the motor 7 is started to drive the screw rod 8 to rotate, the screw rod 8 rotates to drive the moving block 9 to move back and forth along the track of the guide rod 23 and the guide hole 24, the moving block 9 drives the transmission rod 10, the transmission frame 11 and the cleaning ring 5 to move back and forth, the cleaning ring 5 moves back and forth to drive the cleaning block 6 to remove the waste chips on the surface of the guide rail 4, thereby improving the transmission of the workbench.

[0047] When the transmission frame 11 moves, the gas collecting box 12 and the first extrusion block 19 and other structures are driven to move, when the first extrusion block 19 is in contact with the surface of the second extrusion block 20, the first extrusion block 19, the push rod 18, the push block 17 and the piston 22 are driven to move upward by the extrusion, the air in the gas collecting box 12 is extruded, the gas enters the compression box 15 through the transmission pipe 14, when the first extrusion block 19 is not in contact with the second extrusion block 20, the elastic force of the spring 21 drives the first extrusion block 19, the push rod 18, the push block 17 and the piston 22 to move downward, at this time, the gas collecting box 12 is in negative pressure, the gas enters the gas collecting box 12 through the air inlet pipe 13, and the cycle is repeated, the gas in the compression box 15 is intermittently compressed, when the gas in the compression box 15 reaches the limit of the one-way pressure valve, the gas is intermittently sprayed to the surface of the slide rail through the jet pipe 16, and the fine waste is removed.

[0048] It should be noted that the motor 7 is a device or equipment existing in the prior art or a device or equipment that can be realized in the prior art, and the power supply specific composition and principle of the motor 7 are clear to those skilled in the art, and therefore will not be described in detail.
