Description

Technical Field

[0001] The present invention relates to the technical field of die steel processing, and specifically to a taper shank type double - head milling machine. Background Technique

[0002] Under the background of the rapid development of modern manufacturing industry, as a key basic material, die steel is an indispensable core element in the high - precision die manufacturing in high - end manufacturing fields such as automobiles, aerospace, and electronic equipment. The precision, quality, and production efficiency of die manufacturing largely depend on the processing technology of die steel, which makes the performance and technical level of die steel processing equipment highly concerned.

[0003] Currently, during the processing of die steel, most traditional milling machines are equipped with a single milling cutter. Its tool installation structure is relatively single. When processing die steel, it mainly processes different parts of the die steel or performs different processes through a single cutter in sequence. When facing the processing tasks of die steel with complex structures, such as simultaneously completing multiple processes such as milling planes, milling grooves, and milling inclined planes, or processing large - area die steel, this single - cutter processing method requires frequent tool changes and adjustment of processing parameters, and can only process one part and one process at a time. Due to the low processing efficiency of a single milling cutter, the processing cycle of die steel is long, making it difficult to meet the increasing demand for mass production. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a taper shank type double - head milling machine, which solves the problem that most traditional milling machines are equipped with a single milling cutter, and due to the low processing efficiency of a single milling cutter, the processing cycle of die steel is long, making it difficult to meet the increasing demand for mass production.

During processing, the moving plate drives the cleaning structure to move, sweeping the chips generated during processing into the two collection boxes, which not only saves labor but also facilitates the recycling of chips, solving the problem that most traditional milling machines are equipped with a single milling cutter, and due to the low processing efficiency of the single milling cutter, the processing cycle of die steel is long, making it difficult to meet the increasing demand for mass production.

[0015] Preferably, the bottom of the base is evenly and fixedly connected with support legs, and the top of the base fits with the bottom of the U-shaped cleaning brush.

[0016] Working principle: When in use, the mold steel to be processed is placed and limited by the moving plate, and the mounting block is driven by the hydraulic cylinder to move vertically up and down above the base, so that the milling cutter moves vertically up and down above the base, and the motor drives the shaft to rotate, drives the taper handle to move in the mounting seat, and makes the milling cutter run to process the mold steel. The rotation of the shaft drives several limit bars and limit rings to rotate with the shaft as the center, and the limit bars limit the gears, so that the gears are driven by the rotation of the shaft and rotate with the shaft as the center, so that the T-shaped slider slides in The electric push rod drives the gear to slide on the rotating shaft and the limit bar, so that the tooth end of the gear can mesh with the tooth end of the rack according to the processing requirements, driving the I-shaped slider to move inside the T-shaped slide, thereby driving the mounting seat and the milling cutter to move horizontally back and forth, and then adjusting the horizontal front and back positions of the two milling cutters according to the processing requirements, and driving the milling cutter to run, and detecting the position of the mounting seat in real time through the displacement sensor, so as to adjust the front and back positions of the two milling cutters according to the processing requirements of the mold steel, and process the mold steel to enhance the processing efficiency.

[0017] The slider is driven by the electric slide to move inside the electric slide, thereby driving the mold steel on the moving plate to move horizontally left and right above the base, so that the left and right position of the mold steel can be adjusted according to the processing requirements of the mold steel, and it is processed by two milling cutters, thereby further enhancing the processing efficiency, and the moving plate is used to drive the two U-shaped mounting blocks to move left and right, so that the U-shaped cleaning brush is used to clean the debris generated by processing on the base, so that it can fall into the second collection box, or fall into the first collection box through the second cavity, and the magnetic parts inside the baffle chips are used to adsorb the splashed debris generated by the processing so that it is adsorbed on the side opposite to the baffle chips, and the U-shaped cleaning brush is used to clean the debris adsorbed on the baffle chips so that it falls on the base, and then is cleaned into the second collection box by the U-shaped cleaning brush, or falls into the first collection box through the second cavity, thereby realizing automatic cleaning and collection of the debris generated when the double-head milling machine processes the mold steel, without the need for manual and time-consuming cleaning of the debris.

[0018] The present invention provides a taper shank double-head milling machine. It has the following beneficial effects: 1. The present invention drives the mounting block to move up and down through a hydraulic cylinder to achieve the adjustment of the milling cutter in the vertical direction. The adjustment structure drives the milling cutter to rotate and move horizontally back and forth. The electric slide rail drives the moving plate and the die steel to move left and right. In cooperation with the multi-directional movement of the milling cutter, the die steel is processed in all directions. Two milling cutters work simultaneously to process the same processes of different workpieces or multiple identical features of the same workpiece in parallel, reducing the processing time and increasing the processing output per unit time. Thus, it solves the problem that most traditional milling machines are equipped with a single milling cutter, and due to the low processing efficiency of the single milling cutter, the processing cycle of the die steel is long, making it difficult to meet the increasing demand for mass production.

[0019] 2. The present invention uses a baffle to block the debris generated during the processing of the die steel, preventing the debris from splashing everywhere. The electric slide rail drives the moving plate to move horizontally left and right above the base, thereby being able to adjust the left and right positions of the die steel. At the same time, it drives the cleaning structure to move horizontally left and right on the base, thus cleaning the debris generated by the processing on the base into the second collection box and the first collection box, realizing the automatic cleaning and collection of the debris generated when the double-headed milling machine processes the die steel. There is no need for manual labor to clean the debris laboriously, which enhances the practicality of this milling machine and is convenient for subsequent re-melting and recycling of the debris, improving the material utilization rate.

[0020] 3. The present invention drives the rotating shaft to rotate through a motor, so that the milling cutter can process the die steel according to the processing requirements of the die steel. At the same time, the gear rotates around the rotating shaft, and the electric push rod drives the gear to slide on the rotating shaft and the limiting strip, so that the gear can mesh with the rack according to the processing requirements to adjust the horizontal front and back positions of the milling cutter.

[0023] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Please refer to the attached Figure 1 - attached Figure 8 , the embodiment of the present invention provides a taper shank type double-headed milling machine, which includes a base 1. One side of the base 1 is fixedly connected with a mounting plate 6. The top of the mounting plate 6 is fixedly provided with a hydraulic cylinder 7. The output end of the hydraulic cylinder 7 is fixedly connected with a mounting block 8. An adjusting structure is symmetrically arranged inside the mounting block 8. One side of the adjusting structure is fixedly connected with a mounting seat 10. A displacement sensor 11 is installed on the opposite side of the mounting seat 10. A taper shank 31 is installed inside the mounting seat 10. One end of the taper shank 31 is installed with a milling cutter 12. One side of the top of the base 1 is symmetrically and fixedly provided with an electric slide rail 29. A slider 30 is arranged inside the electric slide rail 29. The top of the slider 30 is fixedly connected with a moving plate 13. A cleaning structure is symmetrically and fixedly connected to one side of the moving plate 13. A first collection box 3 is installed on one side of the bottom of the base 1. A second collection box 5 is installed on the other side of the base 1. Baffle chips 4 are symmetrically and fixedly connected to the top of the base 1.

[0025] Specifically, the base 1 provides an installation position for each structure. The hydraulic cylinder 7 is installed through the mounting plate 6. Through the operation of the hydraulic cylinder 7, the mounting block 8 is driven to move vertically up and down above the base 1, thereby driving the two adjusting structures inside the mounting block 8 to move up and down, and further driving the mounting seat 10 and the taper shank 31 inside the mounting seat 10 to move up and down, so that the milling cutter 12 moves vertically up and down above the base 1. The milling cutter 12 is installed through the taper shank 31, making the stability of the milling cutter 12 higher.

[0026] By adjusting the operation of the adjustment structure, the taper shank 31 is driven to rotate inside the mounting seat 10, thereby driving the milling cutter 12 to operate through the taper shank 31. Thus, it is possible to conveniently machine die steel according to the processing requirements of die steel. And by adjusting the operation of the adjustment structure, the two mounting seats 10 can be driven to move horizontally forward and backward, approaching or separating from each other on one side of the mounting block 8, thereby driving the two milling cutters 12 to move horizontally forward and backward. Through the operation of the displacement sensor 11, the position of the mounting seat 10 is detected in real time. Thus, the front and rear positions of the two milling cutters 12 can be adjusted respectively according to the processing requirements of die steel to machine die steel, enhancing the processing efficiency.

[0027] The die steel to be processed is placed on the moving plate 13, and the die steel is limited on the moving plate 13 by using corresponding fixtures or positioning pins. Through the operation of the two electric slide rails 29 on one side of the top of the base 1, the slider 30 is driven to move inside the electric slide rail 29, and then the moving plate 13 is driven to move horizontally left and right above the base 1, thereby driving the die steel on the moving plate 13 to move horizontally left and right above the base 1. Thus, the left and right positions of the die steel can be adjusted according to the processing requirements of die steel, and it is processed by the two milling cutters 12, further enhancing the processing efficiency. The two milling cutters 12 can process different workpieces in parallel with the same process, or simultaneously mill multiple identical features of the same workpiece, improving the processing output per unit time, realizing synchronous and efficient milling processing of multiple parts of die steel, and thus solving the problem that most traditional milling machines are equipped with a single milling cutter. Due to the low processing efficiency of a single milling cutter, the processing cycle of die steel is long, making it difficult to meet the increasing demand for mass production.

[0028] The baffle chip 4, the first collection box 3 and the second collection box 5 are respectively installed through the base 1. The baffle chip 4 is on both sides of the base 1 to block the chips generated during the machining of die steel, preventing the chips from splashing everywhere. By the horizontal movement of the moving plate 13, the cleaning structure is driven to move horizontally left and right on the base 1, thereby cleaning the chips generated by the machining on the base 1 into the second collection box 5 and the first collection box 3. Thus, it realizes the automatic cleaning and collection of the chips generated when the double - head milling machine machines die steel, without the need for manual labor to clean the chips laboriously, enhancing the practicability of this milling machine, and facilitating the subsequent remelting and reuse of the chips, improving the material utilization rate.

[0029] Please refer to the appendix Figure 1 - appendix Figure 8, a first cavity 9 is provided in the middle of the mounting block 8, T-shaped chutes 16 are symmetrically provided inside the mounting block 8, and a rack 17 is fixedly connected to the middle of the inner wall of the mounting block 8. The cleaning structure includes a U-shaped mounting block 14, one side of the U-shaped mounting block 14 is fixedly connected to one side of the moving plate 13, and a U-shaped cleaning brush 15 is mounted on the other side of the U-shaped mounting block 14. A magnetic member 28 is provided inside the baffle chip 4, and one side of the baffle chip 4 opposite to each other is attached to one side of the U-shaped cleaning brush 15. A second cavity 27 is provided on the other side of the top of the base 1, and the first collection box 3 communicates with the second cavity 27 of the base 1. Support legs 2 are evenly and fixedly connected to the bottom of the base 1, and the top of the base 1 is attached to the bottom of the U-shaped cleaning brush 15.

[0030] Specifically, through the setting of the first cavity 9 and the T-shaped chute 16 of the mounting block 8, an installation space is provided for the adjustment structure. Through the setting of the rack 17, it can cooperate with the adjustment structure, facilitating the movement of the adjustment structure on one side of the mounting block 8. The moving plate 13 is driven by the slider 30 to move horizontally left and right on the base 1, thereby driving the two U-shaped mounting blocks 14 to move left and right, and further driving the U-shaped cleaning brush 15 to move left and right. Thus, by the movement of the U-shaped cleaning brush 15, the debris generated during processing on the base 1 is swept, enabling it to fall into the second collection box 5 or fall into the first collection box 3 through the second cavity 27. Through the magnetic member 28 inside the baffle chip 4, the flying debris generated during processing is adsorbed, making it adsorbed on the opposite side of the baffle chip 4, and the U-shaped cleaning brush 15 is used to sweep the debris adsorbed on the baffle chip 4, making it fall onto the base 1 and then being swept by the U-shaped cleaning brush 15 into the second collection box 5 or falling into the first collection box 3 through the second cavity 27. Thus, it realizes the automatic cleaning and collection of the debris generated when the double-headed milling machine processes die steel, without the need for laborious cleaning of the debris.

[0031] Please refer to the appendix Figure 1 - appendix Figure 5 , the adjustment structure includes a motor 19, the output end of the motor 19 is fixedly connected to a rotating shaft 20, one end of the rotating shaft 20 is fixedly connected to the other end of the taper shank 31, the circumferential outer wall of the rotating shaft 20 is symmetrically rotatably connected to I-shaped sliders 18, the top and bottom of the I-shaped sliders 18 are slidably connected in the T-shaped chutes 16 of the mounting block 8, one side of the motor 19 is fixedly arranged on one side of one of the I-shaped sliders 18, and one side of the other I-shaped slider 18 is fixedly connected to one side of the mounting seat 10.

[0032] Specifically, the operation of the motor 19 drives the rotation of the rotating shaft 20, thereby driving the taper shank 31 to operate within the mounting seat 10. The rotating shaft 20 is limited by two I-shaped sliders 18, making the rotation of the rotating shaft 20 more stable. Through the sliding connection between the I-shaped sliders 18 and the T-shaped sliding grooves 16 of the mounting block 8, it is convenient for the entire adjustment structure to slide on one side of the mounting block 8. Moreover, through the cooperation between the I-shaped part of the I-shaped slider 18 and the T-shaped part of the T-shaped sliding groove 16, the stability of the movement is enhanced. One of the I-shaped sliders 18 is used to mount the motor 19, and the other I-shaped slider 18 is used to mount the mounting seat 10. Thus, through the operation of the motor 19, the taper shank 31 is driven to operate, enabling the milling cutter 12 to process the die steel according to the processing requirements of the die steel.

[0033] Please refer to the appendix Figure 1 - appendix Figure 5 , a plurality of limiting strips 21 are uniformly and fixedly connected to the outer wall of the rotating shaft 20. Limiting rings 22 are fixedly connected to both ends of the limiting strips 21, and the middle parts of the limiting rings 22 are fixedly connected to the outer wall of the rotating shaft 20. A gear 23 is slidably connected to the outer wall of the limiting strip 21. The middle part of the gear 23 is slidably connected to the outer wall of the rotating shaft 20, and the tooth end of the gear 23 can be meshed with the tooth end of the rack 17. A T-shaped annular sliding groove 24 is formed on one side of the gear 23. A T-shaped slider 26 is slidably connected in the T-shaped annular sliding groove 24 of the gear 23. One side of the T-shaped slider 26 is fixedly connected to an electric push rod 25, and one side of the electric push rod 25 is fixedly connected to the other side of one of the I-shaped sliders 18. Both the gear 23 and the rack 17 are located in the first cavity 9 of the mounting block 8.

[0034] Specifically, by using the rotation of the rotating shaft 20, a plurality of limiting strips 21 are driven to rotate on the rotating shaft 20 with the rotating shaft 20 as the center, and the limiting rings 22 are also driven to rotate. Through the limitation of the gear 23 by the limiting strip 21, the gear 23 is driven by the rotation of the rotating shaft 20 to rotate with the rotating shaft 20 as the center. Moreover, through the sliding connection between the gear 23 and the limiting strip 21 and the rotating shaft 20, the gear 23 can move horizontally left and right on the rotating shaft 20 and the limiting strip 21 and be driven to rotate. Furthermore, the tooth end of the gear 23 can be meshed with the tooth end of the rack 17. Thus, when the tooth end of the gear 23 is meshed with the tooth end of the rack 17, the I-shaped slider 18 is driven to move inside the T-shaped sliding groove 16, thereby driving the mounting seat 10 and the milling cutter 12 to move horizontally back and forth. Furthermore, according to the processing requirements, the positions of the two milling cutters 12 are adjusted, and the milling cutter 12 is driven to operate to process the die steel.

[0035] When the gear 23 is driven to rotate, the T-shaped slider 26 slides within the T-shaped annular chute 24. Thus, through the shape fit between the T-shaped slider 26 and the T-shaped annular chute 24, and through the operation of the electric push rod 25, the T-shaped slider 26 is driven to move horizontally left and right, and further drives the gear 23 to slide on the rotating shaft 20 and the limiting strip 21. Thereby, the gear 23 can mesh with the rack 17 according to the processing requirements to adjust the horizontal front and rear positions of the milling cutter 12.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
