Description

Technical Field

[0001] This utility model belongs to the field of CNC machine tool technology and relates to a workpiece grinding machine tool with a self-cleaning guide rail function. Background Technology

[0002] When machining parts, machine tools spray coolant onto the parts and cutting tools. After machining, lubricating and rust-preventive oil is sprayed onto the guide rail components of the machine tool to maintain it. In environments with a lot of dust, corrosive gases, or coolant splashes, the lubricant needs to be checked and replenished more frequently.

[0003] The existing patent document with authorization publication number CN220145442U discloses an automatic feeding machine tool for centerless grinding, including a feeding table, a platen fixedly disposed on the inner side of the top of the second slide, a feeding cylinder fixedly disposed at the rear end of the feeding table, a rubber gasket fixedly disposed at the rear end of the feeding cylinder, a sleeve plate fixedly disposed at the top of the feeding table, a drive gear plate and an abrasive gear plate rotatably disposed inside the sleeve plate, a collar fixedly disposed on the internal support rod of the abrasive gear plate, a frosting layer fixedly disposed inside the collar, a base plate fixedly disposed at the top of the feeding table, and an abrasive motor fixedly disposed at the front end of the base plate.

[0004] However, the aforementioned existing technologies still have the following problems:

[0005] After the workpiece is processed, the high-temperature metal shavings generated during processing fly into the gaps of the slide rail. As the temperature drops, the metal shavings mix with the lubricating oil in the guide rail and harden, adhering firmly to the gaps of the slide rail, thus forming hard deposits that affect the movement of the slider.

[0006] The patent document with authorization publication number CN221921692U discloses a dustproof shaft support guide rail, which includes a guide rail base, a slider on the guide rail base, and a plurality of first mounting holes on the end face of the slider; it also includes a dustproof sheet, which is detachably connected to the slider; and a dustproof bellows cover is detachably installed on one end of the dustproof sheet.

[0007] However, the aforementioned existing technologies still have the following problems:

[0008] Although the dustproof bellows cover of the above-mentioned prior art can block most of the metal debris from the column, some of the smaller metal debris can still enter the gaps of the guide rail through the dustproof bellows cover and mix with the lubricating oil in the guide rail gaps. Over time, hard deposits that are difficult to clean will gradually form in the guide rail gaps, thus affecting the normal movement of the slider. Utility Model Content

[0009] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a workpiece grinding machine tool with a self-cleaning function for guide rails, so as to solve the problems mentioned in the background technology. This utility model can effectively clean the hard deposits formed after high-temperature metal waste chips fly into the gaps of the guide rails, so as to avoid affecting the movement of the slider.

[0010] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0011] A workpiece grinding machine tool with a self-cleaning guide rail function includes a machine tool. The top of the machine tool is provided with a longitudinal guide rail assembly and a transverse guide rail assembly that are perpendicular to each other. The longitudinal guide rail assembly includes two parallel longitudinal guide rails, and the transverse guide rail assembly includes two parallel transverse guide rails. Its characteristic feature is that:

[0012] Each guide rail is slidably mounted with two sliders, and the top of the four sliders in the same group of guide rail assemblies, which are arranged in a rectangular pattern, is fixed with a slide table.

[0013] Two square pipes are fixedly connected to one end of each slider, and the openings of the square pipes face the gap between the guide rails. Each slider has a cavity inside, which is connected to the two corresponding square pipes through two channels.

[0014] A heating assembly is fixed at the bottom of the slide table. The heating assembly includes a heating box and a fan. The heating box is equipped with an electric heating wire. The fan is connected to the heating box through an air inlet pipe. The heating box is connected to the cavities of the four corresponding sliders through four delivery pipes.

[0015] Furthermore, the machine tool is fixed with several industrial cameras, and each of the several industrial camera groups corresponds one-to-one with a number of guide rail gaps, with each industrial camera located at one end of the corresponding guide rail gap.

[0016] Furthermore, a scraping assembly is detachably mounted on one end of the slider by bolts. The scraping assembly includes two symmetrically arranged mounting seats. A U-shaped scraper is fixed on the side of the mounting seat facing the guide rail, and the outer wall of the scraper is in contact with the inner wall surface of the gap between the guide rail and the slide rail.

[0017] Furthermore, the scraping assembly also includes a U-shaped connecting seat, which spans above the two mounting seats and is fixedly connected to the slider by a first bolt. Each mounting seat has a vertically upward connecting block at its top, and an elastic element is fitted on the connecting block. The bottom of the U-shaped connecting seat has two mounting slots for inserting the elastic element. A second bolt is symmetrically threaded on one side of the U-shaped connecting seat, and one end of the second bolt passes through the connecting block, the elastic element, and the mounting slot.

[0018] Furthermore, the back of the scraper is provided with two parallel guide blocks, and the mounting base is provided with guide grooves that match the guide blocks. The scraper can achieve lateral position adjustment through the sliding cooperation between the guide groove and the guide block. A spring is fixed between the guide block and the inner wall of the guide groove.

[0019] Furthermore, a grinding motor is fixed to the top of the slide table located on the two parallel transverse guide rails, a grinding wheel is fixed to the output end of the grinding motor, and a pneumatic clamp is fixed to the top of the slide table located on the two parallel longitudinal guide rails.

[0020] Furthermore, each guide rail is provided with a collection box on both sides, and the top of the machine tool has a mounting hole for the collection box to be snapped in and fixed. Inside the machine tool, there are two vacuum cleaners that correspond one-to-one with the longitudinal slide rail assembly and the transverse slide rail assembly, respectively. The vacuum cleaners are connected to the four collection boxes of the corresponding slide rail assembly through four suction pipes, and the collection boxes have a collection port at the top.

[0021] The beneficial effects of this utility model are:

[0022] This invention, through the combination of a heating component and a cavity, channel, and directional pipe connected to one end of the slider, utilizes a hot air system that generates high-temperature airflow via an electric heating wire. This effectively softens the hard deposits formed by the mixture of metal scrap and lubricating oil adhering to the guide rail gaps, thus preventing interference with slider movement. Simultaneously, a scraping component with a spring-guided structure (guide block + spring) ensures elastic contact with the guide rail gaps, facilitating the cleaning of metal debris. This effectively solves the technical problem of the inconvenience of cleaning hard deposits formed by the mixture of metal scrap and lubricating oil in the guide rails, thus extending the service life of the guide rails.

[0023] This invention incorporates a collection box and a vacuum cleaner. When the vacuum cleaner is activated, it creates negative pressure through the suction pipe, drawing debris through the collection port and suction pipe. This reduces the likelihood of metal debris adhering to the gaps in the guide rails, improves the cleaning quality of the guide rails, and extends their maintenance cycle.

[0037] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0038] Example 1

[0039] like Figure 1-5As shown, a workpiece grinding machine tool with a self-cleaning guide rail function includes a machine tool 1. The top of the machine tool 1 is provided with a longitudinal slide rail assembly and a transverse slide rail assembly that are perpendicular to each other. The longitudinal slide rail assembly includes two parallel longitudinal guide rails 2, and the transverse slide rail assembly includes two parallel transverse guide rails 2. Each guide rail 2 is slidably mounted with two sliders 3. The top of the four sliders 3 in the same group of slide rail assemblies, which are arranged in a rectangular shape, is fixed with a slide table 4.

[0040] Two square pipes 5 are fixedly connected to one end of each slider 3, and the opening 6 of the square pipes 5 is directly opposite the guide rail gap 32; each slider 3 has a cavity 7 inside, and the cavity 7 is connected to the corresponding two square pipes 5 through two channels 33 respectively.

[0041] A heating assembly is fixed at the bottom of the slide table 4. The heating assembly includes a heating box 8 and a fan 9. The heating box 8 is equipped with an electric heating wire 10. The fan 9 is connected to the heating box 8 through an air inlet pipe 11. The heating box 8 is connected to the cavities 7 of four corresponding sliders 3 through four conveying pipes 12. Several industrial cameras 13 are fixed on the machine tool 1. The industrial cameras 13 are arranged in a one-to-one correspondence with several guide rail gaps 32. The industrial cameras 13 are located at one end of the corresponding guide rail gap 32. The industrial cameras 13 are configured in a one-to-one correspondence with the guide rail gaps 32 to realize real-time visual detection of the cleaning effect. The camera data can be connected to the PLC control system to establish a cleaning effect feedback and adjustment mechanism. A grinding motor 25 is fixed at the top of the slide table 4 located on two parallel transverse guide rails 2. A grinding wheel 26 is fixed at the output end of the grinding motor 25. A pneumatic clamp 27 is fixed at the top of the slide table 4 located on two parallel longitudinal guide rails 2.

[0042] like Figure 3-9 As shown, a scraping assembly is detachably mounted on one end of the slider 3 via bolts. The scraping assembly includes two symmetrically arranged mounting seats 14. A U-shaped scraper block 15 is fixed to the side of the mounting seat 14 facing the guide rail 2. The outer wall of the scraper block 15 is in contact with the inner wall surface of the guide rail gap 32. The scraping assembly also includes a U-shaped connecting seat 16, which spans above the two mounting seats 14 and is fixedly connected to the slider 3 via a first bolt 17. Each mounting seat 14 has a vertically upward connecting block 18 at its top. The connecting block 18 is fitted with an elastic element 19, which is a deformable rubber block. The elastic element 19 has a fixing hole for the connecting block 18 to be embedded. The elastic element 19 is set at the connection between the U-shaped connecting seat 16 and the mounting seat 14 to effectively prevent the vibration generated at the scraper block 15 from affecting the slider 3. The bottom of the U-shaped connecting seat 16 has two mounting grooves 20 for the elastic element 19 to be inserted. The U-shaped connecting seat 16 is symmetrically threaded with a second bolt 21 on one side. One end of the second bolt 21 passes through the connecting block 18, the elastic element 19 and the mounting groove 20.

[0043] The back of the scraper block 15 is provided with two parallel guide blocks 22. The mounting base 14 is provided with a guide groove 23 that matches the guide blocks 22. The scraper block 15 achieves lateral position adjustment through the sliding cooperation between the guide groove 23 and the guide block 22. A spring 24 is fixed between the guide block 22 and the inner wall of the guide groove 23.

[0044] The specific operation method of Embodiment 1 of this utility model is as follows:

[0045] The industrial camera 13 is turned on, and the lens focal length is calibrated to cover the entire length of the guide rail gap 32. At the same time, parameters are set on the external PLC control interface. When large hard particles are detected in the guide rail gap 32, the electric heating wire 10 is started to preheat, and then the fan 9 is started to blow air into the heating box 8 through the air inlet pipe 11. The hot air in the heating box 8 is delivered to the cavities 7 of the four corresponding sliders 3 through the four delivery pipes 12. The hot air in the cavity 7 enters the square pipe 5 through the channel 33. The hot air is sprayed out from the square pipe 5 and sprayed into the guide rail gap 32, which softens the solidified lubricating oil. During the movement of the slide table 4, the scraper 15 scrapes off the residue. The industrial camera 13 acquires images of the guide rail gap 32 in real time and detects the amount of debris residue through the image processing algorithm. When the amount of debris residue in the guide rail gap 32 reaches the standard, the heating component is automatically turned off.

[0046] In this first embodiment of the utility model, the heating component and the cavity 7, channel 33 inside the slider 3 and the directional tube connected to one end of the slider 3 are configured in coordination. The hot air system generates a high-temperature airflow through the electric heating wire 10, which effectively softens the hard deposits that are a mixture of metal scraps and lubricating oil in the guide rail 2 attached to the guide rail gap 32, thereby avoiding affecting the movement of the slider 3. At the same time, by setting up a scraping component, the scraper 15 adopts a spring 24 guiding structure (guide block 22 + spring 24) to achieve elastic contact with the guide rail gap 32, thereby facilitating the cleaning of metal debris in the guide rail gap 32.

[0047] Example 2

[0048] like Figure 10-11 As shown, each guide rail 2 is provided with a collection box 28 on both sides. The top of the machine tool 1 has a mounting hole for the collection box 28 to be snapped in and fixed. There are two vacuum cleaners 29 fixed inside the machine tool 1, which correspond one-to-one with the longitudinal slide rail assembly and the transverse slide rail assembly, respectively. The vacuum cleaners 29 are connected to the four collection boxes 28 of the corresponding slide rail assembly through four suction pipes 30. The collection box 28 has a collection port 31 at the top.

[0049] The specific operation method of this embodiment two is as follows:

[0050] When the vacuum cleaner 29 is turned on, the vacuum cleaner 29 creates negative pressure through the suction pipe 30, which collects the debris through the collection port 31 and the suction pipe 30, thereby reducing the possibility of metal debris adhering to the guide rail gap 32.

[0051] This utility model embodiment 2 uses a collection box 28 and a vacuum cleaner 29 to collect and recycle metal debris, thereby reducing the possibility of metal debris adhering to the guide rail gap 32, improving the cleaning quality of the guide rail 2, and extending the service life of the guide rail 2.

[0052] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
