Technical Field

[0001] This utility model relates to the field of machine tool guard technology, and in particular to a machine tool guard that is convenient for maintenance. Background Technology

[0002] Machine tool guards are key components for protecting machine tools. Their core function is to prevent external impurities (such as iron filings, dust, oil, coolant, etc.) from entering the machine tool, avoiding wear, corrosion, or blockage of precision components such as guide rails, lead screws, and bearings, thereby extending the service life of the machine tool and improving machining accuracy.

[0003] However, existing machine tool guards often have the problem of being inconvenient to install and remove, making them difficult to inspect and maintain on a daily basis.

[0004] Therefore, it is necessary to provide a machine tool cover that is easy to inspect and maintain to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the technical problems of existing machine tool guards being inconvenient to install and disassemble, and difficult to maintain, this utility model provides a machine tool guard that is easy to maintain.

[0006] The machine tool guard provided by this utility model for convenient maintenance includes: an annular housing fixedly sleeved on the machine tool body; a connecting plate fixedly installed on the inner wall of the annular housing; a bidirectional screw rotatably installed on the connecting plate; a slider threaded onto the bidirectional screw; a mounting seat fixedly installed on the slider; a guard body installed on the mounting seat; a positioning mechanism provided on the mounting seat for installing and locking the guard body; and an opening and closing mechanism installed on the inner wall of the annular housing for controlling the opening and closing of the guard body.

[0007] Preferably, a plug is fixedly installed at the bottom of the protective cover body, and the plug has a pin hole.

[0008] Preferably, the mounting base has a slot, and the inner wall of one side of the slot has a mounting groove and a positioning hole. A connecting block is fixedly installed on the inner wall of the mounting groove.

[0009] Preferably, the positioning mechanism includes: a one-way screw rotatably mounted on the connecting block and rotatably connected to the inner wall of the mounting groove; a sliding plate threaded onto the one-way screw; a pin fixedly mounted on the sliding plate and adapted to the pin hole and the positioning hole; and a transmission mechanism mounted on the inner wall of the mounting groove.

[0010] Preferably, the transmission mechanism includes: a worm gear rotatably mounted on the inner wall of the mounting groove, one end of the worm gear extending to the outside of the mounting base; a worm wheel fixedly sleeved on the one-way screw and meshing with the worm gear; and a knob fixedly mounted on one end of the worm gear.

[0011] Preferably, a limiting groove is formed on the bottom inner wall of the annular shell, and a strip-shaped opening is formed on the annular shell. The slider is slidably connected to the inner walls on both sides of the limiting groove and the strip-shaped opening.

[0012] Preferably, the opening and closing mechanism includes: a dual-axis motor fixedly installed on the inner wall of the annular housing; a transmission rod installed on the output shaft of the dual-axis motor via a coupling; a bevel gear installed on one end of the transmission rod and meshing with the bidirectional screw; and a limiting plate fixedly installed on the inner wall of the annular housing and rotatably connected to the transmission rod.

[0013] Compared with related technologies, the machine tool cover provided by this utility model, which facilitates maintenance, has the following beneficial effects: This utility model provides a machine tool guard for convenient maintenance. Two bidirectional screws rotate, driving multiple sliders, multiple mounting seats, multiple inserts, and two guard bodies to move closer or further apart, thereby controlling the opening and closing of the two guard bodies. The two guard bodies protect the machine tool body. A positioning mechanism facilitates both installation and locking of the guard bodies, as well as disassembly and maintenance. An opening and closing mechanism controls the opening and closing of the guard bodies. Inserts with pin holes, in conjunction with the positioning mechanism, facilitate both installation and locking of the guard bodies, as well as disassembly and maintenance. Inserts can be inserted into slots, and the positioning mechanism can be installed in mounting grooves. A knob... The worm gear rotates, which in turn drives the worm wheel to rotate. The worm wheel then drives the one-way screw to rotate, which in turn moves the sliding plate laterally. The sliding plate then moves the pin laterally, thus separating the pin from the pin hole and the positioning hole, thereby releasing the locking state of the insert block. This makes the disassembly and maintenance of the protective cover body more convenient. The limiting groove can guide and limit the slider, and the strip opening allows the slider to extend to the outside of the mounting base. The dual-axis motor drives two transmission rods to rotate, and the two transmission rods drive two bidirectional screws to rotate through multiple bevel gears. The rotation of the two bidirectional screws causes multiple sliders, multiple mounting bases, multiple insert blocks, and two protective cover bodies to move closer or further apart, thereby controlling the opening and closing of the two protective cover bodies.

[0017] Please refer to the following: Figure 1-3 ,in, Figure 1 A schematic diagram of a preferred embodiment of the machine tool cover for convenient maintenance provided by this utility model; Figure 2 for Figure 1 A top-view sectional structural diagram; Figure 3 for Figure 1 The enlarged schematic diagram of part A shown in the figure illustrates a machine tool guard for easy maintenance. The guard includes: an annular housing 2 fixedly fitted onto the machine tool body 1; a connecting plate 3 fixedly installed on the inner wall of the annular housing 2; a bidirectional screw 4 rotatably mounted on the connecting plate 3; a slider 5 threaded onto the bidirectional screw 4; a mounting seat 6 fixedly mounted on the slider 5; a guard body 7 mounted on the mounting seat 6; a positioning mechanism on the mounting seat 6 for locking the guard body 7; and an opening and closing mechanism on the inner wall of the annular housing 2 for controlling the opening and closing of the guard body 7. The two bidirectional screws 4 rotate, causing multiple sliders 5, multiple mounting seats 6, multiple inserts 8, and two guard bodies 7 to move closer or further apart, thereby controlling the opening and closing of the two guard bodies 7. The two guard bodies 7 protect the machine tool body 1. The positioning mechanism facilitates not only the installation and locking of the guard bodies 7 but also their disassembly and maintenance. The opening and closing mechanism controls the opening and closing of the guard bodies 7.

[0018] The bottom of the protective cover body 7 is fixedly installed with a plug 8. The plug 8 has a pin hole 9. The plug 8 with the pin hole 9, together with the positioning mechanism, can not only facilitate the installation and locking of the protective cover body 7, but also facilitate the disassembly and maintenance of the protective cover body 7.

[0019] The mounting base 6 has a slot 10, and a mounting groove 11 and a positioning hole are provided on one inner wall of the slot 10. A connecting block 12 is fixedly installed on the inner wall of the mounting groove 11. The insert block 8 can be inserted through the slot 10, and the positioning mechanism can be installed through the mounting groove 11.

[0020] The positioning mechanism includes: a one-way screw 13 rotatably mounted on the connecting block 12 and rotatably connected to the inner wall of the mounting groove 11; a sliding plate 14 threaded onto the one-way screw 13; a pin 15 fixedly mounted on the sliding plate 14 and adapted to the pin hole 9 and the positioning hole; and a transmission mechanism mounted on the inner wall of the mounting groove 11, which drives the worm gear 16 to rotate via a knob 18, the worm gear 16 rotates and the worm wheel 17 rotates, the worm wheel 17 drives the one-way screw 13 to rotate, the one-way screw 13 rotates and drives the sliding plate 14 to move laterally, the sliding plate 14 drives the pin 15 to move laterally, thereby separating the pin 15 from the pin hole 9 and the positioning hole, thereby releasing the locking state of the insert block 8, thus making the disassembly and maintenance of the protective cover body 7 more convenient.

[0021] The transmission mechanism includes: a worm gear 16 rotatably mounted on the inner wall of the mounting groove 11, one end of which extends to the outside of the mounting base 6; a worm wheel 17 fixedly sleeved on the one-way screw 13 and meshing with the worm gear 16; and a knob 18 fixedly mounted on one end of the worm gear 16. The knob 18 drives the worm gear 16 to rotate, which in turn drives the worm wheel 17 to rotate. The worm wheel 17 drives the one-way screw 13 to rotate, which in turn drives the sliding plate 14 to move laterally. The sliding plate 14 drives the pin 15 to move laterally, thereby separating the pin 15 from the pin hole 9 and the positioning hole, thus releasing the locking state of the insert block 8 and making the disassembly and maintenance of the protective cover body 7 more convenient.

[0022] A limiting groove 19 is provided on the bottom inner wall of the annular housing 2, and a strip opening 20 is provided on the annular housing 2. The slider 5 is slidably connected to the inner walls on both sides of the limiting groove 19 and the strip opening 20. The limiting groove 19 can guide and limit the slider 5, and the strip opening 20 can extend the slider 5 to the outside of the mounting base 6.

[0023] The opening and closing mechanism includes: a dual-axis motor 21 fixedly installed on the inner wall of the annular housing 2, the model of the dual-axis motor 21 being STP-28D300X; a transmission rod 22 installed on the output shaft of the dual-axis motor 21 via a coupling; a bevel gear 23 installed on one end of the transmission rod 22 and meshing with the bidirectional screw 4; and a limiting plate 24 fixedly installed on the inner wall of the annular housing 2 and rotatably connected to the transmission rod 22. The dual-axis motor 21 drives the two transmission rods 22 to rotate, and the two transmission rods 22 drive the two bidirectional screws 4 to rotate via multiple bevel gears 23. The rotation of the two bidirectional screws 4 causes multiple sliders 5, multiple mounting seats 6, multiple inserts 8, and two protective cover bodies 7 to move closer or further apart, thereby controlling the opening and closing of the two protective cover bodies 7.

[0024] The working principle of the machine tool cover that facilitates maintenance provided by this utility model is as follows: The two transmission rods 22 are driven to rotate by the dual-axis motor 21. The two transmission rods 22 drive the two bidirectional screws 4 to rotate through multiple bevel gears 23. The rotation of the two bidirectional screws 4 causes multiple sliders 5, multiple mounting seats 6, multiple inserts 8 and two protective cover bodies 7 to move closer or further apart, thereby controlling the opening and closing of the two protective cover bodies 7. When the protective cover body 7 needs to be disassembled, the worm gear 16 is rotated by the knob 18. The worm gear 16 rotates and the worm wheel 17 rotates. The worm wheel 17 drives the one-way screw 13 to rotate. The rotation of the one-way screw 13 drives the sliding plate 14 to move laterally. The sliding plate 14 drives the pin 15 to move laterally, thereby separating the pin 15 from the pin hole 9 and the positioning hole, thereby releasing the locking state of the insert block 8, making the disassembly and maintenance of the protective cover body 7 more convenient.

[0025] Compared with related technologies, the machine tool cover provided by this utility model, which facilitates maintenance, has the following beneficial effects: This utility model provides a machine tool guard for convenient maintenance. Two bidirectional screws 4 rotate, driving multiple sliders 5, multiple mounting seats 6, multiple inserts 8, and two guard bodies 7 to move closer or further apart, thereby controlling the opening and closing of the two guard bodies 7. The two guard bodies 7 protect the machine tool body 1. A positioning mechanism facilitates both installation and locking of the guard bodies 7, as well as disassembly and maintenance. An opening and closing mechanism controls the opening and closing of the guard bodies 7. Inserts 8 with pin holes 9, in conjunction with the positioning mechanism, facilitate both installation and locking of the guard bodies 7, as well as disassembly and maintenance. Inserts 8 can be inserted into slots 10, and the positioning mechanism can be installed in mounting slots 11. A knob 18 drives a worm gear 16 to rotate. The worm gear 17 rotates, which drives the one-way screw 13 to rotate. The rotation of the one-way screw 13 drives the sliding plate 14 to move laterally. The sliding plate 14 drives the pin 15 to move laterally, thereby separating the pin 15 from the pin hole 9 and the positioning hole, thus releasing the locking state of the insert 8. This makes it easier to disassemble and repair the cover body 7. The slider 5 can be guided and limited by the limiting groove 19. The slider 5 can be extended to the outside of the mounting base 6 by the strip opening 20. The two transmission rods 22 are driven to rotate by the dual-axis motor 21. The two transmission rods 22 drive the two bidirectional screws 4 to rotate through multiple bevel gears 23. The rotation of the two bidirectional screws 4 causes multiple sliders 5, multiple mounting bases 6, multiple inserts 8 and two cover bodies 7 to move closer or further apart, thereby controlling the opening and closing of the two cover bodies 7.
