Description

Technical Field

[0001] The invention relates to the technical field of turbine disc processing, in particular to a large-stroke high-speed broaching machine. Background Art

[0002] In the broaching process of aircraft engine turbine disks, the machining accuracy of the tenon and groove is directly related to the overall performance of the engine. Among them, the broaching of the turbine disk tenon and groove is mainly achieved through the movement of the broach. Therefore, how to apply and replace the broach is one of the core issues in the turbine disk machining process.

[0003] The prior art discloses an automated production line for turbine disc mortise and tenon broaching, comprising a loading and unloading unit, a broaching unit, a tool changing unit, and a control system for signal communication with the above units. The loading and unloading unit, the broaching unit, and the tool changing unit of the automated production line can automatically operate according to a preset program under the control of the control system, which not only greatly improves work efficiency and reduces labor intensity, but also avoids human errors introduced by manual operation in the prior art, improves processing accuracy, and reduces the defective rate and scrap rate of the turbine disc.

[0004] In the prior art, a broaching machine generally uses a single broach for broaching. When the broach reaches the end of its service life, it needs to be replaced with a new broach before broaching can continue. However, in actual production applications, in order to have high versatility, the broach box is huge in size and can only be replaced slowly and steadily by mechanical equipment, resulting in a long waiting time, which seriously affects the broaching efficiency. Similarly, once the broach has an abnormality, such as chipping, it is impossible to quickly replace the broach, affecting work efficiency. In addition, in multi-step broaching processes, such as rough drawing, semi-finishing drawing, and finishing drawing, different broaches are often required for coordinated processing, and the time for replacing the broach limits the broaching efficiency of the turbine disc, resulting in an extension of the production cycle and economic losses. Summary of the invention

[0005] In order to solve the problem of long time for replacing broaches in the prior art, the present invention provides a large-stroke high-speed broaching machine with the function of continuously using multiple broaches to improve the broaching efficiency of turbine discs.

At least two groups are installed; when broaching the turbine disk workpiece 802, the main bed 100 of the machine tool drives the two broaching boxes 602 to slide repeatedly along the main linear rail 102 of the machine tool in turn, so that the turbine disk workpiece 802 undergoes plastic flow and forms chips under the pressure of the blade of the broach 6021, and finally forms the required fir-tree-shaped tenon or special-shaped groove; and the two broaches 6021 are broached at the same time, which can effectively improve the work efficiency, and the two broaches 6021 can be replaced at the same time, reducing the number of times the broaches 6021 are replaced, thereby further improving the work efficiency. Embodiment 2:

[0089] This embodiment optimizes the technical solution based on the embodiment 1: the interaction component 101 includes: Figure 4 The driving gear 1011 shown in the figure is arranged on the side of the main transmission rack 903, a servo motor 1012 is arranged above the driving gear 1011, a sliding frame 1013 is arranged on one side of the servo motor 1012, and a sliding frame 1013 is arranged on one side of the sliding frame 1013. Figure 6 The servo cylinder 1014 shown in the figure and the bottom end of the sliding frame 1013 are slidably connected to the limiting guide rail 1015.

[0090] The top of the driving gear 1011 is fixedly connected as Figure 6 The transmission column 10111 shown, the output end of the servo motor 1012 is fixedly connected to the top of the transmission column 10111, and the middle part of the transmission column 10111 is rotatably connected to the sliding frame 1013; the bottom end of the driving gear 1011 is fixedly connected to the rotating column 10112, and the bottom end of the rotating column 10112 is rotatably connected to the sliding frame 1013;

[0091] One side of the servo motor 1012 is fixedly connected to the sliding frame 1013; the bottom of the sliding frame 1013 is fixedly connected to the main bed 100 of the machine tool; the output end of the servo cylinder 1014 is fixedly connected to the sliding frame 1013, and the bottom of the servo cylinder 1014 is fixedly connected to the main bed 100 of the machine tool.

[0092] In this embodiment, at least four groups of interactive components 101 are arranged inside the main bed 100 of the machine tool, and the interval between two interactive components 101 is less than the length of the broaching box 602, so as to ensure that the main transmission rack 903 corresponding to the broaching box 602 can be meshed with any driving gear 1011; when broaching the turbine disc workpiece 802, the worker can control the servo cylinder 1014 to make the driving gear 1011 close to the main transmission rack 903 and mesh with the main transmission rack 903, thereby controlling the servo motor 1 012, drives the main transmission rack 903 to move, thereby making the broach box 602 slide along the main linear rail 102 of the machine tool; when a main transmission rack 903 leaves the periphery of a driving gear 1011, the worker can control the servo cylinder 1014 to retract the driving gear 1011, thereby reducing energy consumption and avoiding conflicts with other components; in addition, since the servo motor 1012 can flexibly control the rotation direction of the driving gear 1011, the worker can design the movement direction and path of each broach box 602.

[0093] Assuming that the two broach boxes 602 on the main bed 100 of the machine tool are regarded as station A and station B respectively, under normal conditions, the broach 6021 on station A first passes through the turbine disk workpiece 802 for broaching, and finally moves to the very end of the main bed 100 of the machine tool, and the broach 6021 on station B follows behind and also passes through the turbine disk workpiece 802 for broaching, and then the broaching is reversed, with station B broaching first and station A broaching again, and then returning to the initial position, completing a double-station synchronous broaching work with high work efficiency; in actual production, since the service life of each broach 6021 is not necessarily the same, if the broach 6021 on station B needs to be replaced but station A does not need to be replaced, the worker can leave station B at the initial position and replace the broach 6021, while station A is still broaching. After the broach 6021 is replaced, the two stations are allowed to broach synchronously again, which greatly reduces the impact of replacing the broach 6021 on station B on work efficiency. Embodiment 3:

[0094] This embodiment optimizes the technical solution based on the embodiment 2: the tool magazine 600 includes the following Figure 8 The storage platform 601 shown in FIG. 6 is disposed on a side of the main bed 100 of the machine tool away from the main slide 900 of the machine tool. A plurality of guide rail bases 6011 are disposed on the side of the storage platform 601. A plurality of guide rail bases 6011 are disposed on the top of the storage platform 601.

[0097] The track plate 6013 is slidably connected to the side away from the guide rail base 6011 as shown in FIG. Fig.16 The rotating slide 6071 shown in FIG. 1 has a detachable connection on one side of the rotating slide 6071. Fig.17 The tool mounting station 607 shown;

[0098] A tool holder 608 is provided below the track plate 6013 , and one side of the tool holder 608 is fixedly connected to the guide rail base 6011 .

[0099] A movable arm 701 is disposed at the top of the front bed 700 of the machine tool, and a movable arm 701 is disposed at one end away from the front bed 700 of the machine tool. Fig. 9 Control panel 702 is shown.

[0100] A plurality of hydraulic clamps 801 are arranged on the side of the turbine disc workpiece 802 , and a lubricating oil distributor 803 is arranged on the side of the turbine disc workpiece 802 close to the main bed 100 of the machine tool.

[0101] The upper part of the broach 6021 is provided with Fig.12 The broach pressing block 6022 shown in the figure has a loading and unloading groove 6024 on one side of the broach box 602 close to the broach pressing block 6022 , and a hydraulic rod 6025 is provided on one side of the broach pressing block 6022 close to the broach box 602 , and the output end of the hydraulic rod 6025 is fixedly connected to the broach pressing block 6022 .

[0102] The top and side of the broach box 602 are fixedly connected with a plurality of lifting columns 6023, the lifting columns 6023 include a lifting base 60233, the lifting base 60233 is fixedly connected to the upper surface of the broach box 602, the top of the lifting base 60233 is fixedly connected with a mandrel 60232, and the top of the mandrel 60232 is fixedly connected with a Fig.15 Lift cap 60231 is shown.

[0103] The bottom end of the broach box 602 is fixedly connected with a docking column 6026 , and the bottom end of the tool mounting platform 607 is provided with a docking groove 6072 , the size of which matches the docking column 6026 , and the inner side of the tool mounting platform 607 is provided with a plurality of slots 6073 .

[0104] In this embodiment, the storage platform 601 can store the broach box 602 and move the broach box 602 through the robot arm 605, which solves the problem that the broach box 602 is large in size and inconvenient to move manually in actual work, and the operation of workers replacing the broach 6021 can be separated by replacing the broach box 602, thereby further improving work efficiency; in addition, the tool holder 6015 is based on related equipment in the prior art and can identify the broach box 602, so different types of broaches 6021 can be stored in advance in actual work; in addition, when the broach 6021 on the A station needs to be replaced, the second suspension guide rail 604 is first moved along the first suspension guide rail 603 to the top of the A station, and the robot arm 605 then moves along the second suspension guide rail 604 to the lifting column at the top of the broach box 602 6023 is aligned, the lifting column 6051 is lowered, and the main slide 900 of the machine tool reserves space for the lifting column 6051 to descend, so that the lifting column 6023 is clamped by the pneumatic clamp 6052, and then the zero-point positioning clamp 902 releases the lifting column 6023 on the side of the broach box 602, and the second suspension guide rail 604 first moves along the first suspension guide rail 603, driving the robot arm 605 to pull the broach box 602 out of the main slide 900 of the machine tool, and then the lifting column 6051 is raised, and the broach box 602 is moved to the storage platform 601 by using the first suspension guide rail 603, the second suspension guide rail 604 and the lifting column 6051, completing the disassembly of the broach box 602, and during this process, the B station can perform broaching work; similarly, the broach box 602 is operated in the opposite direction, and the new broach box 602 can be installed on the A station.

[0105] Furthermore, when the broach 6021 needs to be replaced at workstation B and the broach box 6021 does not need to be replaced at workstation A, since the robot arm 605 only interacts with the initial position of workstation A in order to save production costs, the worker can control the moving path of workstation A, so that workstation A does not return to the initial position during broaching, and at the same time, workstation B moves to the corresponding position, and then use the robot arm 605 to replace the broach box 602 on workstation B without interrupting the broaching work, thereby improving work efficiency.

[0106] In addition, after the broach 6021 on the broach box 602 reaches its service life, the worker must replace it. Therefore, the robot arm 605 can move the broach box 602 to the tool loading platform 607 after removing the broach box 602; the tool loading platform 607 is aligned with the broach box 602 through the docking groove 6072, and limits the movement of the broach box 602 through the slot 6073. When the broach box 602 is placed in the tool loading platform 607, since the tool loading platform 607 is on the back of the machine tool main bed 100 and the robot arm 605 cannot turn the broach box 602, the broach 6021 faces the machine tool main bed 100, which makes it inconvenient for the worker to replace the broach 6021. At this time, the rotating slide 6071 can be used to rotate the tool loading platform 607 so that the broach 6021 faces upward, which is convenient for the worker to replace the broach 6021, and the worker can temporarily store the broach 6021 on the tool holder 608, which further facilitates the worker's operation.

[0107] In addition, in actual work, since the models of the broach box 602 are also diverse, a single tool mounting table 607 may not be able to meet actual needs. Therefore, the rotating slide 6071 can be moved along the track plate 6013 to facilitate the replacement of the tool mounting table 607, and can also adapt to tool mounting tables 607 of different sizes to improve applicability.

[0108] Experimental example:

[0109] like Fig.18 As shown, this experimental example takes a turbine disc processing plant as an example. In this experimental example, when the turbine disc processing plant is processing the turbine disc, it is found that the fifth broaching tool box 602 in the tool magazine 600 needs to be assembled to the A station, recorded as tool No. 5, and the sixth broaching tool box 602 needs to be assembled to the B station, recorded as tool No. 6. This experimental example uses enumeration method to prove that the operation can be completed according to different pre-position states of the broach 6021.

[0110] The T(N)A-UP command indicates that tool N is returned from station A to the tool box position N, and the T(N)B-DOWN command indicates that tool N is loaded from the tool box position N to station B. When N=0, it indicates that no assembly or return operation is performed:

[0111] Both broach boxes 602 are not at the workstations: let the broach box 602 at workstation A be a, and the broach box 602 at workstation B be b, then the operations to be performed are T(a) A-UP, T(5) A-DOWN, T(b) B-UP, and T(6) B-DOWN.

[0112] There is a broach box 602 on the workstation: This situation needs to be further divided into four categories for discussion:

[0113] (1) Tool No. 5 is at station A: Let the broach box 602 at station B be b. The operations to be performed are T(0) A-UP, T(0) A-DOWN, T(b) B-UP, and T(6) B-DOWN.

[0114] (2) Tool No. 5 is at station B: Assume that the broach box 602 at station A is a. The operations to be performed are T(0) A-UP, T(0) A-DOWN, T(5) B-UP, T(6) B-DOWN, T(a) A-UP, T(5) A-DOWN, T(0) B-UP, T(0) B-DOWN.

[0115] (3) Tool No. 6 is at station A: Let the broach box 602 at station B be b. The operations to be performed are T(6) A-UP, T(5) A-DOWN, T(b) B-UP, and T(6) B-DOWN.

[0116] (4) Tool No. 6 is at station B: Let the broach box 602 at station A be a. The operations to be performed are T(a) A-UP, T(5) A-DOWN, T(0) B-UP, and T(0) B-DOWN.

[0117] Both broach boxes 602 are on the workstations: if broach No. 5 is on workstation A and broach No. 6 is on workstation B, the requirements are obviously met at this time.

[0118] When tool No. 5 is at station B and tool No. 6 is at station A, the operations that need to be performed are T(6) A-UP, T(0) A-DOWN, T(5) B-UP, T(6) B-DOWN, T(0) A-UP, T(5) A-DOWN, T(0) B-UP, T(0) B-DOWN.

[0119] In summary, it can be concluded that in any case, the function of assembling tool No. 5 to station A and tool No. 6 to station B can be realized. Due to the arbitrariness of the broaching tool box 602, it can be concluded that the broaching machine can realize the function of assembling any two broaching tool boxes 602 to stations A and B through a series of operations.

[0120] Furthermore, the state of the broach box 602 during the broaching operation can be divided into a start cycle, a working cycle, and an end cycle. The start cycle refers to placing the two broach boxes 602 into the A station and the B station in sequence, the working cycle refers to replacing the broaches 6021 in the order of the A station and the B station assuming that the service life of each broach 6021 is fixed, and the end cycle refers to taking the broach boxes 602 on the A station and the B station back into the tool magazine 600.
