Description

Technical Field

[0001] The utility model relates to the technical field of lathes, in particular to a lathe with a protective function. Background Art

[0002] A lathe in which the tool moves along two axes in linkage, also called a two-axis linkage lathe or a two-axis CNC lathe, means that the two axes of the lathe can move synchronously or in coordination, and complex processing of the workpiece can be achieved by precisely controlling the relative position between the tool and the workpiece.

[0003] A Chinese patent discloses a two-axis rail vertical CNC lathe (authorization announcement number CN216680256U), in which the cooling baffle assembly includes a baffle and a universal spherical cooling nozzle; a snap-in groove is provided on the bottom surface of the baffle; the two baffles are respectively snapped onto the top edges of the left side wall and the front side wall of the base through the snap-in groove; the setting of the baffle can prevent waste chips and coolant from splashing everywhere, playing a role of protection and isolation; the baffle is set in a snap-in installation form, which is easy to install and disassemble.

[0004] According to the above reference case, the above device uses a snap-on baffle to prevent waste chips and coolant from splashing everywhere. Since the above baffle needs to be removed as a whole during the removal process, waste chips and coolant are adhered to the inner side of the baffle. At this time, the waste chips and coolant can be easily shaken off from the moving baffle, which can easily pollute the external environment.

[0005] Therefore, a lathe with a protective function is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present invention is to provide a lathe with a protective function in order to solve the above problems, thereby improving the problem that the existing lathe with a protective function in which the tool moves in a two-axis linkage manner easily pollutes the external environment during the loading and unloading of the protective baffle.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a lathe with a protective function, including a two-axis linkage lathe and a protective device, wherein the protective device is installed on the outside of the two-axis linkage lathe; the protective device includes a U-shaped protective baffle slidably connected to the outside of the two-axis linkage lathe, and an electric cylinder is fixedly connected to the outside of the U-shaped protective baffle.

[0008] Preferably, a U-shaped scraper is fixedly connected to the inner side of the two-axis linkage lathe, and the outer side of the U-shaped scraper is in sliding contact with the inner side of the U-shaped protective baffle. When the workpiece is processed, the staff drives the U-shaped protective baffle down to an unobstructed position through an electric cylinder. This does not require the staff to disassemble and use the U-shaped protective baffle, which also reduces the staff's workload. In addition, the U-shaped protective baffle is scraped by the U-shaped scraper during the downward movement. The U-shaped scraper can scrape off the processing debris and coolant adhering to the inner side of the U-shaped protective baffle and guide it back to the base, preventing the processing debris and coolant from contaminating the external environment. At the same time, it can also ensure that the U-shaped protective baffle can be raised and lowered without hindrance.

[0009] Preferably, a piston cavity is provided at the bottom of the U-shaped protective baffle, and a plurality of air guide ports are provided on the inner wall of the U-shaped protective baffle respectively connected to the plurality of piston cavities, the openings of the air guide ports are facing the vertical inner wall of the U-shaped protective baffle, and the protective device further comprises an enhanced cleaning mechanism, which comprises a plurality of piston blocks respectively slidably connected to the interior of the plurality of piston cavities, and the bottom of each of the piston blocks is fixedly connected to a guide rod, the bottom of the guide rod slides through the piston cavity and extends to the outside and is fixedly connected to the bottom outer wall of the two-axis linkage lathe. The enhanced cleaning mechanism can actively squeeze the air inside the piston cavity to sweep the inner wall of the U-shaped protective baffle and the surface of the U-shaped scraper during the downward movement of the U-shaped protective baffle, which can not only improve the cleaning effect of the inner side of the U-shaped protective baffle, but also reduce the machining debris or coolant on the surface of the U-shaped scraper being carried up by the U-shaped protective baffle during the upward movement of the U-shaped protective baffle.

[0010] Preferably, the outer wall of the U-shaped protective baffle is provided with a plurality of air inlets, each of which is in communication with the plurality of piston cavities. A one-way valve is embedded in each of the air guide ports and each air inlet. The one-way valve disposed within the air guide port allows air to flow from the interior of the piston cavity toward the air guide port, while the one-way valve disposed within the air inlet allows air to flow from the air inlet toward the interior of the piston cavity. The two one-way valves restrict external air from entering the piston cavity only through the air inlet, while allowing air within the piston cavity to be discharged only through the air guide port, thereby achieving the purpose of one-way air guidance.

[0011] Preferably, a dust screen is installed on the outer wall of the U-shaped protective baffle at the position corresponding to each air inlet, which can prevent external dust from being carried into the piston cavity by the air, thereby ensuring that the piston block can slide normally inside the piston cavity.

[0012] Preferably, the surface of each guide rod is sheathed with a rubber bellows, the upper and lower ends of which are fixedly connected to the bottom outer wall of the two-axis linkage lathe and the bottom surface of the U-shaped protective baffle. This prevents external dust from adhering to the surface of the guide rod, thereby reducing the relative sliding friction between the guide rod and the piston cavity. Preferably, the top of the U-shaped scraper is recessed downward and forms a slope with an angle of 45 degrees to the horizontal plane. This guides the scraped processing debris and coolant into the base, keeping the processing debris and coolant away from the U-shaped protective baffle.

[0013] Preferably, the number of the electric cylinders is two, and the two electric cylinders are symmetrically distributed on both sides of the U-shaped protective baffle, which can make the lifting of the U-shaped protective baffle more stable.

[0014] The beneficial effects of the utility model are:

[0015] 1. In the present invention, when the workpiece is processed, the worker moves the U-shaped protective baffle down to an unobstructed position through the electric cylinder. This eliminates the need for the worker to disassemble and use the U-shaped protective baffle, thereby reducing the worker's workload. In addition, the U-shaped protective baffle is scraped by the U-shaped scraper during the downward movement. The U-shaped scraper can scrape off the processing debris and coolant adhering to the inner side of the U-shaped protective baffle and guide them back to the base, thereby preventing the processing debris and coolant from contaminating the external environment. At the same time, it can also ensure that the U-shaped protective baffle can be raised and lowered without hindrance.

[0016] 2. The enhanced cleaning mechanism in the present invention can actively squeeze the air inside the piston cavity to blow the inner wall of the U-shaped protective baffle and the surface of the U-shaped scraper during the downward movement of the U-shaped protective baffle. This can not only improve the cleaning effect of the inner side of the U-shaped protective baffle, but also reduce the processing debris or coolant on the surface of the U-shaped scraper being carried up by the U-shaped protective baffle during the upward movement of the U-shaped protective baffle.

[0022] 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.

[0023] When implementing: Figure 1-4 As shown, a lathe with a protective function includes a two-axis linkage lathe 1 and a protective device 2, and the protective device 2 is installed on the outside of the two-axis linkage lathe 1; the two-axis linkage lathe 1 includes a base, a spindle assembly, and a turret assembly. The U-shaped protective baffle 21 is slidably connected to the surface of the base, and the U-shaped scraper 24 is fixedly connected to the surface of the base. Since the above structures are all structures disclosed in the comparative cases, the specific connection methods, usage methods and models of the specific structures themselves are the same as those in the comparative cases, and they will not be repeated here.

[0024] like Figure 2 、 Figure 3 and Figure 4 As shown, the protective device 2 includes a U-shaped protective baffle 21 slidably connected to the outside of the two-axis linkage lathe 1, and the outside of the U-shaped protective baffle 21 is fixedly connected to an electric cylinder 22; the inside of the two-axis linkage lathe 1 is fixedly connected to a U-shaped scraper 24, and the outside of the U-shaped scraper 24 is in sliding contact with the inside of the U-shaped protective baffle 21; the top of the U-shaped scraper 24 is concave downward and forms a slope with an angle of forty-five degrees with the horizontal plane; the number of electric cylinders 22 is two, and the two electric cylinders 22 are symmetrically distributed on both sides of the U-shaped protective baffle 21.

[0025] Before the two-axis linkage lathe 1 processes the workpiece normally, the staff can manually control the extension rod of the electric cylinder 22 to extend, and the extension rod of the electric cylinder 22 drives the U-shaped protective baffle 21 to rise to a preset height. At this time, the base cooperates with the U-shaped protective baffle 21 to surround the workpiece, the spindle assembly and the turret assembly on the inside to prevent processing debris or coolant from splashing to the outside during processing.

[0026] like Figure 3 and Figure 4As shown, a plurality of piston cavities 211 are provided at the bottom of the U-shaped protective baffle 21, and a plurality of air guide ports 212 are provided on the inner side of the U-shaped protective baffle 21, which are respectively connected to the plurality of piston cavities 211. The openings of the air guide ports 212 face the vertical inner wall of the U-shaped protective baffle 21. The protective device 2 also includes an enhanced cleaning mechanism 23. The enhanced cleaning mechanism 23 includes a plurality of piston blocks 231 respectively slidably connected to the interior of the plurality of piston cavities 211. The bottom of each piston block 231 is fixedly connected to a guide rod 232. The bottom of the guide rod 232 slides through the piston cavity 211 and extends to the outside and is fixedly connected to the bottom outer wall of the two-axis linkage lathe 1.

[0027] The outer wall of the U-shaped protective baffle 21 is provided with a plurality of air inlets 213, each of which is connected to the plurality of piston chambers 211. A one-way valve 233 is embedded in each air guide port 212 and each air inlet 213. The one-way valve 233 disposed within the air guide port 212 allows air to flow from the interior of the piston chamber 211 toward the air guide port 212, while the one-way valve 233 disposed within the air inlet 213 allows air to flow from the air inlet 213 toward the interior of the piston chamber 211. A dust screen 234 is installed on the outer wall of the U-shaped protective baffle 21, corresponding to each air inlet 213. A rubber bellows 235 is sheathed on the surface of each guide rod 232. The upper and lower ends of the rubber bellows 235 are fixedly connected to the bottom outer wall of the two-axis linkage lathe 1 and the bottom surface of the U-shaped protective baffle 21, respectively.

[0028] During the downward movement of the U-shaped protective baffle 21, the U-shaped protective baffle 21 synchronously drives the piston chamber 211 to move downward. At this time, the piston block 231 moves toward each other relative to the U-shaped protective baffle 21. At this time, the air inside the piston chamber 211 is quickly squeezed into the air guide port 212. The air guide port 212 guides the air to the inner wall of the U-shaped protective baffle 21. The high-speed airflow can blow away the processing debris and coolant remaining on the inner wall of the U-shaped protective baffle 21 and the surface of the U-shaped scraper 24. This not only improves the cleaning effect of the inner wall of the U-shaped protective baffle 21, but also reduces the processing debris or coolant on the surface of the U-shaped scraper 24 being carried up by the U-shaped protective baffle 21 during the upward movement of the U-shaped protective baffle 21.

[0029] During the upward movement of the U-shaped protective baffle 21, the U-shaped protective baffle 21 simultaneously drives the piston chamber 211 to move upward. At this time, the piston block 231 moves downward inside the piston chamber 211, causing the air pressure inside the piston chamber 211 to decrease. At this time, the outside air is quickly squeezed into the piston chamber 211 through the air inlet 213.

[0030] When the present invention is in use, after the workpiece processing is completed, the staff can manually control the extension rod of the electric cylinder 22 to retract, and the electric cylinder 22 drives the U-shaped protective baffle 21 to move downward. The U-shaped protective baffle 21 is scraped by the U-shaped scraper 24 during the downward movement. The U-shaped scraper 24 can scrape off the processing debris and coolant adhering to the inner wall of the U-shaped protective baffle 21 and guide it back to the base, so as to avoid the processing debris and coolant from polluting the external environment. In addition, the electric cylinder 22 is used to lift the U-shaped protective baffle 21, which does not require the staff to disassemble and use the U-shaped protective baffle 21, and also reduces the workload of the staff.

[0031] It should be noted that the electric cylinder 22 in the above description is a device with relatively mature application of existing technology. The specific model can be selected according to actual needs. At the same time, the electric cylinder 22 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0032] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
