[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please refer to Figures 1-6 ;

[0024] A modular multi-functional training machine tool includes a machine body 1. A motor 11 and a multi-tooth chuck 12 are provided on one side of the machine body 1. The motor 11 is connected to the multi-tooth chuck 12 for transmission. The multi-tooth chuck 12 is used to fix the workpiece. The transmission connection can be made by using two synchronous pulleys in conjunction with a transmission belt. Specifically, one synchronous pulley is fixed on the output shaft of the motor 11, and the other synchronous pulley is fixed on the multi-tooth chuck 12. In this way, when the motor 11 is running, the power can be effectively transmitted from the motor 11 to the multi-tooth chuck 12 through the cooperation of the synchronous pulley and the transmission belt, thereby driving the workpiece to rotate for processing. A base 2 is also provided on one side of the machine body 1. A first slide rail 3 is provided on the base 2. A first slide block 31 is slidably mounted on the first slide rail 3. A first drive assembly 6 is provided on the base 2 to drive the first slide block 31 to move. A second slide rail 4 is provided on the first slide block 31. A second slide block 41 is slidably mounted on the second slide rail 4. A second drive assembly 7 is provided on the first slide block 31 to drive the second slide block 41 to move. A third slide rail 5 is provided on the second slide block 41. A tool holder 51 is slidably connected on the third slide rail 5. A third drive assembly 8 is provided on the second slide block 41 to drive the tool holder 51 to move. The tool holder 51 is used to install machining tools. By controlling the three drive components, the position of the tool relative to the workpiece can be changed, enabling the tool to process the workpiece. When disassembly or maintenance is required, simply separate the drive components corresponding to the first slide 31, the second slide 41, and the tool holder 51, and the first slide 31, the second slide 41, and the tool holder 51 can slide directly out from the corresponding slide rails, simplifying the disassembly process and improving disassembly and assembly efficiency. The tool holder 51 has a first slide groove 98 on the side away from the multi-tooth chuck 12. A grinding component 9 is slidably connected in the first slide groove 98. The grinding component 9 can slide along the first slide groove 98 to polish the side of the workpiece after processing. A tailstock 33 is also movably installed on the first slide rail 3. The tailstock 33 cooperates with the multi-tooth chuck 12 to clamp longer workpieces, improving stability during processing. The tailstock 33 can slide directly out from the first slide rail 3.

[0025] In this embodiment, the first drive assembly 6 includes a first nut seat 61 fixedly connected to the bottom of the first slide block 31. A first lead screw 62 is inserted inside the first nut seat 61. The length direction of the first lead screw 62 is parallel to the length direction of the machine base 2. One end of the first lead screw 62 is rotatably connected to the side wall of the machine body 1. A support base 21 is fixedly installed at the end of the machine base 2 away from the machine body 1 by screws. The other end of the first lead screw 62 is rotatably connected to the support base 21. The first lead screw 62 extends to the outside of the support base 21 and is fixedly connected to a first feed handwheel 63. The first feed handwheel 63 is fixedly installed together with the first lead screw 62 by screws, which is convenient for disassembly and assembly. When it is necessary to move the first lead screw 62... When moving the slide block 31, simply rotate the first feed handwheel 63 to rotate the first lead screw 62. As the first lead screw 62 rotates, it will drive the first nut seat 61 to move, thereby causing the first slide block 31 to make a corresponding displacement. If it is necessary to disassemble the first slide block 31, rotate the first feed handwheel 63 to drive the first lead screw 62 to move the first nut seat 61 toward the support seat 21 until it is close to the support seat 21. Then, remove the first feed handwheel 63 and the support seat 21 in sequence. This way, the first lead screw 62 can be unscrewed from the first nut seat 61. Finally, slide the first slide block 31 directly out of the first slide rail 3 to complete the disassembly, which greatly simplifies the disassembly steps.

[0026] In this embodiment, the second slide rail 4 is provided with a second slide groove 42, and the first slide block 31 is provided with a fixed seat 32 on the side wall outside the base 2. The second drive assembly 7 includes a second nut seat 71, which is located in the second slide groove 42. A second lead screw 72 passes through the second nut seat 71. The second lead screw 72 and the first lead screw 62 are arranged in a cross shape when viewed from above. One end of the second lead screw 72 extends to the outside of the fixed seat 32 and is equipped with a second feed handwheel 73. The second lead screw 72 is rotatably connected to the fixed seat 32. The cooperation between the fixed seat 32 and the second nut seat 71 ensures that the second lead screw 72 can rotate stably. When it is necessary to move the second slide block 41, the second feed handwheel 73 is rotated to rotate the second lead screw 72. As the second lead screw 72 rotates, it drives the second nut seat 71 to move, thereby causing the second slide block 41 to make a corresponding displacement. When it is necessary to remove the second slide block 41, the second feed handwheel 73 can be turned to move the second nut seat 71 away from the fixed seat 32. When the second nut seat 71 moves a certain distance, it will separate from the second lead screw 72. At this time, the second slide block 41 can be slid out of the second slide rail 4 directly without the use of tools, which greatly improves the efficiency of maintenance and disassembly.

[0027] In this embodiment, the third drive assembly 8 includes a fixed plate 43 disposed on one side of the second slide block 41. A third lead screw 81 is rotatably connected to the fixed plate 43. The third lead screw 81, the third slide rail 5, and the first lead screw 62 are parallel. One end of the third lead screw 81 is threadedly connected to the tool holder 51, and the other end is equipped with a third feed handwheel 82. By rotating the third feed handwheel 82, the third lead screw 81 is rotated, which drives the tool holder 51 to move. When it is necessary to remove the tool holder 51, the tool holder can be moved away from the fixed plate 43 by rotating the third feed handwheel 82. After the tool holder 51 has moved a certain distance, it will separate from the third lead screw 81. At this time, the tool holder 51 can be directly slid off the third slide rail 5 without the use of tools, which greatly improves the efficiency of maintenance and disassembly / reassembly.

[0028] In this embodiment, the grinding component 9 includes a slider 91. One end of the slider 91 located inside the base 2 is provided with a protrusion 92. The protrusion 92 located inside the base 2 has an arc surface that matches the workpiece. The arc surface is used to attach sandpaper. When the workpiece needs to be ground, the slider 91 needs to be pushed towards the workpiece so that the entire arc surface protrudes from the end of the tool, preventing the tool from accidentally touching the workpiece during the grinding process. The sandpaper attached to the arc surface will directly contact the side of the workpiece. As the workpiece rotates, the sandpaper will grind the side of the workpiece. In addition, by controlling the first drive component 6 to move the first slide block 31, the sandpaper can grind different areas of the side of the workpiece.

[0029] In this embodiment, the sliding member 91 has a first locking hole 93 and a second locking hole 94 spaced apart at one end outside the machine base 2. The tool holder 51 has a fixing block 95 at one end outside the machine base 2. The fixing block 95 has a third sliding groove 96, and a locking block 97 is slidably connected in the third sliding groove 96. The locking block 97 is used to insert into the first locking hole 93 or the second locking hole 94 to meet different processing requirements. When performing normal processing operations, the locking block 97 is inserted into the first locking hole 93. At this time, the position of the sliding member 91 ensures that the arc surface does not protrude from the end of the tool, ensuring that it will not affect the processing operation. When grinding is required, first pull the locking block 97 out of the first locking hole 93, then push the sliding member 91 towards the workpiece. When the locking block 97 is aligned with the second locking hole 94, insert the locking block 97 into the second locking hole 94. At this time, the arc surface protrudes from the end of the tool, and the sandpaper attached to the arc surface can contact the side of the workpiece, while the tool will not contact the workpiece. By rotating the workpiece, the side of the workpiece can be effectively ground.
