Abstract

This utility model belongs to the field of drilling and milling machine tools, specifically a drilling and milling integrated machine, including a scrap bin. An X-axis linear module is installed on the top of the scrap bin, a Y-axis linear module is installed on the outer wall of the X-axis linear module, and a Z-axis linear module is installed on the outer wall of the Y-axis linear module. A drive assembly controls two side plates to move closer together, causing two clamping plates to move closer together as well. The two clamping plates slide within the two side plates. At this time, a linkage assembly causes two lower pressure plates to move downwards simultaneously. Thus, while the two clamping plates hold the sides of the workpiece, the two lower pressure plates press down on the top of the workpiece, preventing it from popping up.

Description

Technical Field

[0001] This utility model belongs to the field of drilling and milling machine tools, specifically a drilling and milling integrated machine. Background Technology

[0002] A drilling and milling machine is a machine tool that integrates drilling, milling, boring, and grinding, and is used for processing small and medium-sized parts. It is suitable for processing various small and medium-sized parts, especially non-ferrous metals, plastics, and nylon. It has advantages such as simple structure and flexible operation, and is widely used in single-piece or batch manufacturing. A drilling and milling machine is a small and medium-sized general-purpose metal cutting machine tool; when equipped with an attachment vertical milling head, it can be used for multi-directional milling operations.

[0003] A search revealed a Chinese patent (authorization announcement number CN221560673U) disclosing a coordinate system positioning fixture for a drilling and milling machine. This patented technology includes a red light emitter located between the guide rail and the drilling and milling head. The red light emitter is connected to the guide rail frame via a rotating bracket. When the red light emitter is activated, it projects infrared light onto the workpiece, which is the reference position to be processed by the drilling and milling head, i.e., the center of the drilling and milling head. Adjusting the rotating bracket allows for adjustment of the position of the infrared light. Compared with existing technologies, this invention only requires power to determine the reference position, making operation simple and convenient. Furthermore, the laser positioning is clear and accurate, possessing strong application and promotion value.

[0004] However, existing drilling and milling machine tools have relatively simple workpiece clamping methods, generally only clamping and fixing the workpiece from the side. When a malfunction occurs during drilling and milling, the workpiece is very likely to break off from the operating table, causing accidental injury to surrounding processing personnel. Furthermore, it is not convenient to handle the waste chips after drilling and milling, and the scattered waste chips can easily damage the mechanical parts inside the drilling and milling machine tool. Therefore, this utility model provides a drilling and milling integrated machine. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problem that existing drilling and milling machine tools have a relatively simple workpiece clamping method, generally only clamping and fixing the workpiece from the side, the workpiece is very easy to break off from the operating table when drilling and milling malfunctions, causing accidental injury to surrounding processing personnel, and it is also inconvenient to handle the waste chips after drilling and milling, which can easily damage the mechanical parts inside the drilling and milling machine tool. Therefore, this utility model proposes an integrated drilling and milling machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The present utility model provides a drilling and milling integrated machine, including a scrap bin. An X-axis linear module is provided on the top of the scrap bin. A Y-axis linear module is provided on the outer wall of the X-axis linear module. A Z-axis linear module is provided on the outer wall of the Y-axis linear module. A drilling and milling head is provided on the outer wall of the Z-axis linear module. An operating table is fixedly connected to the top of the scrap bin. A bidirectional lead screw is rotatably connected to the inner wall of the operating table. Two connecting blocks are connected to the outer wall of the bidirectional lead screw through a lead screw and nut pair. The two connecting blocks are symmetrically arranged and slidably connected to the operating table. A drive assembly is provided at the bottom of the operating table. Side plates are fixedly connected to the top of each of the two connecting blocks. Clamping plates are slidably connected to the inner wall of each side plate.

[0007] Preferably, a slider is slidably connected to the inner wall of the side plate, and a tension spring is fixedly connected to the inner wall of the side plate and at the top of the slider. The tension spring is fixedly connected to the side plate. A lower pressure plate is slidably connected to the outer wall of the side plate. One end of the lower pressure plate is fixedly connected to the slider. A linkage component is provided on one side of the clamping plate.

[0008] Preferably, the linkage assembly includes a connecting plate, which is fixedly installed on one side of the clamping plate. Two pull rods are symmetrically fixedly connected to the outer wall of the connecting plate. One end of each pull rod extends into the interior of the side plate. A top rod is fixedly connected between the two pull rods. The outer wall of the slider is provided with an inclined groove for use with the top rod.

[0009] Preferably, one side of the clamping plate and the bottom of the lower pressure plate are both provided with rubber pads.

[0010] Preferably, sealing plates are fixedly connected to both sides of the connecting block, the top of the sealing plate is set as a symmetrical inclined surface, a sealing groove is opened inside the operating table, and the sealing plate fits into the inner wall of the sealing groove.

[0011] Preferably, the drive assembly includes a motor, which is fixedly mounted on the bottom of the operating table. The output end of the motor extends into the interior of the operating table and is fixedly connected to a first bevel gear. A second bevel gear is fixedly connected to the outer wall of the bidirectional lead screw, and the first bevel gear and the second bevel gear are meshed together.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The drilling and milling integrated machine of this utility model controls two side plates to move closer together via a drive assembly, which in turn moves two clamping plates closer together. The two clamping plates clamp and fix the side of the workpiece. As the two side plates continue to move closer together, the two clamping plates slide within the two side plates respectively. At this time, through a set linkage assembly, the two lower pressure plates move downwards simultaneously. Thus, while the two clamping plates clamp the side of the workpiece, the two lower pressure plates press down on the top of the workpiece, preventing the workpiece from popping up. After drilling and milling the workpiece, the two side plates are controlled to move away from each other. Under the action of a tension spring, the lower pressure plates move upwards, thereby resetting the clamping plates. As the two side plates continue to move away from each other, the two clamping plates separate from the workpiece, thus facilitating the removal of the drilled and milled workpiece.

[0014] 2. The drilling and milling integrated machine of this utility model uses a sealing plate to catch the waste chips that fall off the workpiece during drilling and milling. The chips slide down the inclined surface at the top of the sealing plate into the waste bin for collection. As the slider moves, the sealing plates on both sides slide simultaneously in the sealing groove to prevent the waste chips from falling onto the bidirectional lead screw and causing the parts of the drilling and milling machine to jam.

[0026] 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.

[0027] like Figures 1-5 As shown, this utility model provides a technical solution: a drilling and milling integrated machine, including a scrap bin 1. An X-axis linear module 12 is provided on the top of the scrap bin 1. A Y-axis linear module 13 is provided on the outer wall of the X-axis linear module 12. A Z-axis linear module 14 is provided on the outer wall of the Y-axis linear module 13. A drilling and milling head 15 is provided on the outer wall of the Z-axis linear module 14. An operating table 11 is fixedly connected to the top of the scrap bin 1. A bidirectional lead screw 2 is rotatably connected to the inner wall of the operating table 11. Two connecting blocks 21 are connected to the outer wall of the bidirectional lead screw 2 via a lead screw and nut pair. The two connecting blocks 21 are symmetrically arranged and slidably connected to the operating table 11. A drive assembly is provided at the bottom of the operating table 11. Side plates 22 are fixedly connected to the top of each of the two connecting blocks 21. Clamping plates 23 are slidably connected to the inner walls of the side plates 22.

[0028] With the above technical solution, the workpiece is placed on the operating table 11. The two connecting blocks 21 are controlled to move closer to each other by the drive component, which in turn moves the two side plates 22 closer to each other, causing the two clamping plates 23 to move closer to each other. The two clamping plates 23 clamp and fix the side of the workpiece, thus fixing the workpiece on the operating table 11. The drill and milling head 15 is used to perform drilling and milling on the fixed workpiece. The X-axis linear module 12, Y-axis linear module 13, and Z-axis linear module 14 can control the drill and milling head 15 to move in multiple directions, so as to drill and mill different positions of the workpiece.

[0029] Specifically, a slider 31 is slidably connected to the inner wall of the side plate 22, and a tension spring 32 is fixedly connected to the inner wall of the side plate 22 and the top of the slider 31. The tension spring 32 is fixedly connected to the side plate 22, and a lower pressure plate 3 is slidably connected to the outer wall of the side plate 22. One end of the lower pressure plate 3 is fixedly connected to the slider 31, and a linkage component is provided on one side of the clamping plate 23.

[0030] With the above technical solution, when the two side plates 22 approach each other, they drive the two clamping plates 23 to approach each other. When the two clamping plates 23 press against the workpiece, as the two side plates 22 continue to approach each other, the two clamping plates 23 slide within the two side plates 22 respectively. At this time, through the set linkage component, the two lower pressure plates 3 move downwards simultaneously. Thus, while the two clamping plates 23 clamp the sides of the workpiece, the two lower pressure plates 3 press the top of the workpiece, avoiding the phenomenon of the workpiece breaking off.

[0031] Specifically, the linkage assembly includes a connecting plate 24, which is fixedly installed on one side of the clamping plate 23. Two pull rods 34 are symmetrically fixedly connected to the outer wall of the connecting plate 24. One end of each pull rod 34 extends into the interior of the side plate 22. A top rod 35 is fixedly connected between the two pull rods 34. The outer wall of the slider 31 is provided with a slanted groove 33 that cooperates with the top rod 35.

[0032] With the above technical solution, when the clamping plate 23 slides within the side plate 22, it drives the connecting plate 24 to move, causing the two pull rods 34 to slide within the side plate 22, which in turn drives the top rod 35 to move. At this time, the top rod 35 presses against the inclined groove 33 on the outer wall of the slider 31. Under the pressure of the top rod 35, the inclined groove 33 moves downward, causing the slider 31 and the lower pressure plate 3 to move downward, pressing the top of the workpiece. As the slider 31 moves downward, the tension spring 32 is pulled open. After the workpiece is drilled and milled, the two side plates 22 are controlled to move away from each other through the drive assembly. At this time, under the action of the tension spring 32, the slider 31 moves upward, causing the lower pressure plate 3 to move upward, and the clamping plate 23 is reset. As the two side plates 22 continue to move away from each other, the two clamping plates 23 are separated from the workpiece, which facilitates the removal of the workpiece after drilling and milling.

[0033] Specifically, rubber pads 25 are provided on one side of the clamping plate 23 and at the bottom of the lower pressure plate 3.

[0034] The above technical solution increases the friction between the clamping plate 23 and the lower pressure plate 3 on the workpiece by setting the rubber pad 25, resulting in a better fixation effect on the workpiece.

[0035] Specifically, sealing plates 36 are fixedly connected to both sides of the connecting block 21. The top of the sealing plate 36 is set as a symmetrical slope. A sealing groove 37 is opened inside the operating table 11, and the sealing plate 36 fits into the inner wall of the sealing groove 37.

[0036] Through the above technical solution, the waste chips that fall off the workpiece during drilling and milling fall onto the sealing plate 36 and slide down the inclined surface at the top of the sealing plate 36 into the waste bin 1 for collection. As the slider 31 moves, it drives the sealing plates 36 on both sides to slide simultaneously in the sealing groove 37, preventing the waste chips from falling onto the bidirectional lead screw 2 and causing the parts of the drilling and milling machine to jam.

[0037] Specifically, the drive assembly includes a motor 4, which is fixedly installed at the bottom of the operating table 11. The output end of the motor 4 extends into the interior of the operating table 11 and is fixedly connected to a first bevel gear 41. A second bevel gear 42 is fixedly connected to the outer wall of the bidirectional lead screw 2. The first bevel gear 41 and the second bevel gear 42 are meshed together.

[0038] By using the above technical solution, starting the motor 4 can drive the first bevel gear 41 to rotate, causing the second bevel gear 42 to rotate, which in turn drives the bidirectional lead screw 2 to rotate, thereby controlling the clamping of the workpiece.

[0039] In use, the workpiece is placed on the operating table 11, and the motor 4 is started, driving the first bevel gear 41 to rotate, which in turn drives the second bevel gear 42 to rotate, causing the double-acting lead screw 2 to rotate. This brings the two connecting blocks closer together, causing the two side plates 22 to move closer together, and consequently, the two clamping plates 23 to move closer together. Once the two clamping plates 23 are pressed against the workpiece, as the two side plates 22 continue to move closer together, the two clamping plates 23 slide within the two side plates 22 respectively. As the clamping plates 23 slide within the side plates 22, they drive the connecting plate 24 to move, causing the two pull rods 34 to slide within the side plates 22. The push rod 35 moves, pressing against the inclined groove 33 on the outer wall of the slider 31. Under the pressure of the push rod 35, the inclined groove 33 moves downward, causing the slider 31 and the lower pressure plate 3 to move downward, pressing the top of the workpiece. As the slider 31 moves downward, the tension spring 32 is pulled open. Thus, while the two clamping plates 23 hold the sides of the workpiece, the two lower pressure plates 3 press the top of the workpiece, preventing the workpiece from popping up. The rubber pad 25 increases the friction between the clamping plates 23 and the lower pressure plate 3 on the workpiece, resulting in a better fixation effect on the workpiece.

[0040] The drill and milling head 15 is used to drill and mill the fixed workpiece. The X-axis linear module 12, Y-axis linear module 13, and Z-axis linear module 14 can control the multi-directional movement of the drill and milling head 15 to drill and mill different positions of the workpiece. The waste chips that fall off the workpiece during drilling and milling fall onto the sealing plate 36 and slide down the inclined surface at the top of the sealing plate 36 into the waste bin 1 for collection. As the slider 31 moves, it drives the sealing plates 36 on both sides to slide simultaneously in the sealing groove 37 to prevent waste chips from falling onto the bidirectional lead screw 2 and causing the parts of the drilling and milling machine to jam.

[0041] After the workpiece is drilled and milled, the two side plates 22 are moved away from each other by the motor 4. At this time, under the action of the tension spring 32, the slider 31 moves upward, which drives the lower pressure plate 3 to move upward, so that the clamping plate 23 is reset. As the two side plates 22 continue to move away from each other, the two clamping plates 23 are separated from the workpiece, which makes it easier to remove the workpiece after drilling and milling.
