[0002] A gantry machining center (Gantry CNC) is a large machining center with the Z-axis of the spindle perpendicular to the worktable. The overall structure is a portal-like frame composed of two columns and a top beam, with a crossbeam between the columns. It is particularly suitable for machining large and complex workpieces. During machining, a protective door is usually closed to prevent flying chips from injuring the user.

The innovation of the utility model is: it starts by starting through three sets of evenly distributed power motors, and then drives the power shaft to start rotating. The device starts to telescopically move through a pneumatic telescopic rod that is symmetrical on the left and right and can move telescopically, and then drives the scraper to move up and down, thereby realizing automatic cleaning of the rear end face of the hardened glass, thereby ensuring that the user can observe the progress and effect of the processing in time.

[0005] In the prior art, a protective door used to prevent waste chips from flying during the machining process of a gantry machining center is generally embedded with a glass window for observing the machining status of the workpiece. When the gantry machining center is machining the workpiece, in order to prevent the tool from being damaged due to overheating, it is usually cooled by spraying coolant. When the coolant contacts the overheated tool, a large amount of water vapor will be generated, which adheres to the glass window, thereby affecting the user's line of sight. Utility Model Content

[0006] The purpose of the present invention is to provide a protective device for a gantry machining center to solve the problems raised in the above background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A gantry machining center protection device includes a gantry machining center and two protection doors, wherein the protection door is connected to one side of the gantry machining center by transmission, a glass window is fixedly embedded on one side of the protection door, and a wiping mechanism for removing water vapor on the glass window is provided on one side of the protection door;

[0009] The wiping mechanism includes an adsorption block movably arranged on one side of the glass window, one side of the adsorption block is fixedly connected to a support block, one side of the support block is fixedly connected to a transmission block, the top of the transmission block is provided with an electric telescopic rod, the electric telescopic rod is fixedly mounted on the surface of the protective door, and the output end of the electric telescopic rod is fixedly connected to the top of the transmission block;

[0010] The extrusion mechanism is fixedly arranged on the support block and can squeeze out the water adsorbed in the adsorption block.

[0011] By setting up a wiping mechanism, when water vapor adheres to the glass window, the electric telescopic rod is activated to drive the transmission block, support block and adsorption block to move downward.

[0018] By setting a spring, when the first abutting block is not in contact with the second abutting block, the elastic force generated by the spring will drive the first piston, the first extrusion rod and the scraper to move upward, playing a role of reset.

[0019] Preferably, two guide rods are fixedly connected to the top of the support block, and guide blocks are sleeved on the surfaces of the guide rods, and one side of the guide blocks is fixedly connected to one side of the scraper.

[0021] Preferably, one side of the scraper is sloped.

[0022] By setting one side of the scraper in a slope shape, it can avoid the scraper from damaging the adsorption block when it contacts the adsorption block. The slope on the side can play a partial buffering role when squeezing water from the adsorption block.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. The utility model is provided with a wiping mechanism. When water vapor adheres to the glass window, the electric telescopic rod is activated to drive the transmission block, the support block and the adsorption block to move downward. The adsorption block will wipe the water vapor on the glass window while passing through the glass window and adsorb it inside the adsorption block, thereby removing the water vapor without affecting the user's vision.

[0027] 2. The utility model is provided with an extrusion mechanism. When the support block and the transmission block are lowered to a certain height, the second abutting block will contact the first abutting block, and cooperate with the extrusion mechanism to move the scraper downward. The scraper contacts the adsorption block and squeezes out the water in the adsorption block, thereby preventing the adsorption block from being in a saturated state and reducing the adsorption function.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figure 1-Figure 5 , this utility model provides a technical solution:

[0038] The first embodiment of the present invention is as follows: the wiping mechanism includes an adsorption block 4 movably arranged on one side of the glass window 3, a support block 5 fixedly connected to one side of the adsorption block 4, a transmission block 6 fixedly connected to one side of the support block 5, an electric telescopic rod 7 is provided on the top of the transmission block 6, the electric telescopic rod 7 is fixedly mounted on the surface of the protective door 2, and the output end of the electric telescopic rod 7 is fixedly connected to the top of the transmission block 6;

[0039] The extrusion mechanism is fixedly arranged on the support block 5 and can squeeze out the water adsorbed in the adsorption block 4.

[0040] In this embodiment, it is taken into consideration that when the gantry machining center 1 is machining a workpiece, in order to prevent the tool from being damaged due to overheating, a coolant is usually sprayed to cool it down. When the coolant contacts the overheated tool, a large amount of water vapor will be generated, which will adhere to the glass window 3 and affect the user's vision. Therefore, a wiping mechanism is provided. When water vapor adheres to the glass window 3, the electric telescopic rod 7 is activated to drive the transmission block 6, the support block 5 and the adsorption block 4 to move downward. When the adsorption block 4 passes through the glass window 3, it will wipe the water vapor on the glass window 3 and adsorb it inside the adsorption block 4, thereby achieving the effect of removing the water vapor without affecting the user's vision.

[0041] The invention solves the problem that when the gantry machining center 1 processes a workpiece, in order to prevent the tool from being damaged due to overheating, it usually cools it down by spraying coolant. When the coolant contacts the overheated tool, a large amount of water vapor will be generated, which will adhere to the glass window 3 and affect the user's vision.

[0042] Preferably, the adsorption block 4 is made of absorbent cotton, which can absorb water vapor.

[0043] In this embodiment, by setting the material of the adsorption block 4 to absorbent cotton, the adsorption block 4 can adsorb the water vapor when wiping the water vapor on the glass window 3, thereby preventing some water formed by the water vapor from remaining on the surface of the glass window 3.

[0044] Example 2:

[0045] On the basis of the first embodiment, the wiping mechanism in this embodiment can remove the water vapor on the glass window 3 by wiping. However, if the adsorption block 4 in the wiping mechanism is adsorbed to a saturated state, the adsorption function will be significantly reduced, which will affect the effect of removing water vapor. The extrusion mechanism includes a scraper 8 movably arranged on the top of the adsorption block 4, the top of the support block 5 is fixedly connected to the limiting frame 9, the top of the limiting frame 9 is fixedly connected to the first cylinder 10, the interior of the first cylinder 10 is provided with a first piston 11, the bottom of the first piston 11 is fixedly connected to the first extrusion rod 12, the bottom of the first extrusion rod 12 passes through the bottom of the limiting frame 9 and is fixedly connected to the top of the scraper 8;

[0046] The top of the first cylinder 10 is fixedly connected to a transmission pipe 13, one end of the transmission pipe 13 is fixedly connected to a second cylinder 14, the top of the second cylinder 14 is fixedly connected to the bottom of the transmission block 6, a second piston 15 is provided inside the second cylinder 14, the bottom of the second piston 15 is fixedly connected to a second extrusion rod 16, the bottom of the second extrusion rod 16 passes through the bottom of the transmission block 6, and is fixedly connected to a first abutting block 17, and one side of the protective door 2 is fixedly connected to a second abutting block 18 which is opposite to the first abutting block 17.

[0047] In this embodiment, it is taken into consideration that if the adsorption block 4 in the wiping mechanism is adsorbed to a saturated state, the adsorption function will be significantly reduced, which will affect the effect of removing water vapor. Therefore, by providing an extrusion mechanism, when the support block 5 and the transmission block 6 are lowered to a certain height, the second abutting block 18 will contact the first abutting block 17. At this time, under the influence of pressure, the first abutting block 17 will move upward, and at the same time drive the second extrusion rod 16 and the second piston 15 to move upward, squeezing the gas inside the second cylinder 14, so that the gas enters the first cylinder 10 from the transmission pipe 13. At the same time, pushed by the gas, the first piston 11 will move downward, and at the same time drive the first extrusion rod 12 and the scraper 8 to move downward. The scraper 8 contacts the adsorption block 4, which will squeeze out the water in the adsorption block 4, thereby preventing the adsorption block 4 from being in a saturated state and the adsorption function from being reduced.

[0048] The invention solves the problem that if the adsorption block 4 in the wiping mechanism is adsorbed to a saturated state, the adsorption function will be significantly reduced, which will affect the effect of removing water vapor.

[0049] Preferably, the first piston 11 and the second piston 15 are made of rubber, and their outer surfaces are in close contact with the first cylinder 10 and the second cylinder 14 respectively.

[0050] In this embodiment, by setting the material of the first piston 11 and the second piston 15 to rubber, the sealing between the first cylinder 10 and the second cylinder 14 can be improved, so that a closed cavity is formed inside to facilitate the transmission of gas.

[0051] Preferably, a spring 19 is sleeved on the surface of the first extrusion rod 12 , the top of the spring 19 is fixedly connected to the bottom of the first piston 11 , and the bottom of the spring 19 is fixedly connected to the inner wall of the first cylinder 10 .

[0052] In this embodiment, by providing a spring 19, when the first abutting block 17 is not in contact with the second abutting block 18, the elastic force generated by the spring 19 will drive the first piston 11, the first extrusion rod 12 and the scraper 8 to move upward, thereby playing a reset role.

[0053] Preferably, two guide rods 20 are fixedly connected to the top of the support block 5 , and a guide block 21 is sleeved on the surface of the guide rod 20 , and one side of the guide block 21 is fixedly connected to one side of the scraper 8 .

[0054] In this embodiment, by providing the guide rod 20 and the guide block 21, the downward trajectory of the scraper 8 can be limited so that it can only move along the guide rod 20 and the guide block 21, while improving the stability during the movement.

[0055] Preferably, one side of the scraper 8 is sloped.

[0056] In this embodiment, one side of the scraper 8 is set to a slope shape, which can prevent the scraper 8 from damaging the adsorption block 4 when it contacts the adsorption block 4. The slope on the side can play a partial buffering role when squeezing water from the adsorption block 4.

[0057] Working principle: When water vapor adheres to the glass window 3, the electric telescopic rod 7 is activated to drive the transmission block 6, the support block 5 and the adsorption block 4 to move downward. When the adsorption block 4 passes through the glass window 3, it will wipe the water vapor on the glass window 3 and adsorb it inside the adsorption block 4, thereby achieving the effect of removing water vapor without affecting the user's vision;

[0058] At the same time, when the support block 5 and the transmission block 6 drop to a certain height, the second abutting block 18 will contact the first abutting block 17. At this time, under the influence of pressure, the first abutting block 17 will move upward, and at the same time drive the second extrusion rod 16 and the second piston 15 to move upward, squeezing the gas inside the second cylinder 14, so that the gas enters the first cylinder 10 from the transmission pipe 13. At the same time, pushed by the gas, the first piston 11 will move downward, and at the same time drive the first extrusion rod 12 and the scraper 8 to move downward. The scraper 8 contacts the adsorption block 4, which will squeeze out the water in the adsorption block 4, thereby preventing the adsorption block 4 from being in a saturated state and reducing the adsorption function.

[0059] It should be noted that the electric telescopic rod 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 specific composition and principle of the power supply of the electric telescopic rod 7 are clear to those skilled in the art, so they are not described in detail.
