Description

Technical Field

[0001] The present application relates to the technical field of bevel gear processing, and in particular to a spiral bevel gear processing fixture. Background Art

[0002] There are two types of spiral bevel gears. One is the arc bevel gear, in which the axis of the large wheel and the axis of the small wheel intersect; the other is the hypoid spiral bevel gear, in which the axis of the large wheel and the axis of the small wheel have a certain offset. The world-class companies that produce spiral bevel gears are mainly Gleason in the United States and Oerlikon in Switzerland. Spiral bevel gears are widely used in mechanical transmission fields such as automobiles, aviation, and mining due to their large overlap coefficient, strong load-bearing capacity, high transmission ratio, stable transmission, and low noise. Bevel gears and hypoid gears are gear transmission types of intersecting axes and staggered axes respectively. However, there are various classifications based on the characteristics of the tooth length curve, tooth height form, and processing methods. Since the tooth length curve is of great importance to the transmission performance and requires a specific processing method, it is generally classified according to the tooth length curve.

[0003] The existing patent (publication number: CN216028542U) discloses a clamping fixture for processing large-size high-precision spiral bevel gears, which relates to the field of gear processing. In order to solve the problem in the prior art that it is inconvenient to fix large-size high-precision spiral bevel gears when processing them, and it is impossible to adjust and adapt according to different gear shapes and types, a lifting seat is installed above the fixed seat, and a bevel gear to be processed is arranged above the lifting seat, a connecting plate is installed above one side of the base, a lower connecting seat is installed above the connecting plate, an upper connecting seat is installed above the lower connecting seat, a telescopic cylinder and a sliding rod are installed between the upper connecting seat and the lower connecting seat, connecting sleeves are installed on both sides of the outer sides of the upper connecting seat and the lower connecting seat, and limiting clamps are arranged on the front end surfaces of the upper connecting seat and the lower connecting seat, a threaded rod is installed inside the positioning rod, and a connecting rotating cylinder is installed at one end of the threaded rod and the connecting sleeve.

[0004] When the above device is used, different processing operations need to be performed on the gears, and different angles and parts need to be operated. The above device cannot adjust the horizontal and tilt angles of the gears during use. When the gears need to be processed at different angles, the fixture needs to be replaced to work. The scope of application is relatively low. At the same time, the steps in the process of replacing the fixture are relatively cumbersome, resulting in reduced work efficiency. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides a spiral bevel gear processing fixture with advantages such as adjustable angle. It solves the problem that when the above-mentioned device is used, different processing operations need to be performed on the gear at different angles and parts. During use, the above-mentioned device cannot adjust the horizontal and tilt angles of the gear. When the gear needs to be processed at different angles, the fixture needs to be replaced to work, and the scope of application is relatively low. At the same time, the steps in the process of replacing the fixture are relatively cumbersome, resulting in reduced work efficiency.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a spiral bevel gear processing fixture, comprising a base plate, the upper end of the base plate is rotatably connected to an electric turntable mounting plate, the upper end of the electric turntable mounting plate is fixedly connected to an electric turntable, the upper end of the electric turntable is fixedly connected to a workbench, the upper end of the base plate is fixedly connected to an electric cylinder, the telescopic end of the electric cylinder is fixedly connected to a connecting frame, and the lower end of the connecting frame is hinged to the surface of the electric turntable mounting plate.

[0007] The upper end of the workbench is fixedly connected to a module, the upper end of the module is fixedly connected to a first servo motor, the sliding surface inside the module is fixedly connected to an upper fixed plate, both sides of the upper end of the workbench are fixedly connected to bidirectional screw mounting frames, both of the two bidirectional screw mounting frames are rotatably connected with bidirectional screws, and both sides of the upper end of the workbench adjacent to the two bidirectional screw mounting frames are fixedly connected to mounting tables.

[0008] Through the above scheme, an electric turntable mounting plate is rotatably connected to the upper end of the base plate, an electric cylinder is fixedly connected to the upper end of the base plate, and then the telescopic end of the electric cylinder is fixedly connected to a connecting frame, and the lower end of the connecting frame is hinged to the surface of the electric turntable mounting plate. At the same time, an electric turntable is fixedly connected to the upper end of the electric turntable mounting plate, and then the workbench is fixedly connected to the upper end of the electric turntable. When it is necessary to process the gear at different angles, the electric cylinder is started, and the telescopic end of the electric cylinder will drive the connecting frame to move up and down, thereby driving one side of the electric turntable mounting plate to move up and down. At the same time, because the electric turntable mounting plate and the base plate are rotatably connected, the up and down movement of one side of the electric turntable mounting plate will change the structural inclination angle of the electric turntable mounting plate and the upper end of the electric turntable mounting plate. At the same time, the electric turntable is started. Because the upper end of the electric turntable is fixedly connected to the workbench, the electric turntable will drive the workbench to rotate, thereby changing the horizontal angle of the gear fixed at the upper end of the workbench, which can meet the work of processing gears at different angles and has a wide range of applications.

[0009] Furthermore, a second servo motor is fixedly connected to the upper end of the upper fixed plate, and an output end of the second servo motor passes through the upper fixed plate and is fixedly connected to a driving bevel gear.

[0010] Through the above solution, the output end of the second servo motor is fixedly connected to the active bevel gear, so starting the second servo motor will drive the active bevel gear to rotate.

[0011] Furthermore, three threaded column mounting brackets are fixedly connected to the lower end of the upper fixed plate, and threaded columns are rotatably connected inside the three threaded column mounting brackets. One end of the three threaded columns passes through the threaded column mounting brackets and is fixedly connected to driven bevel gears, and the three driven bevel gears are meshed with the active bevel gears.

[0012] Through the above solution, when the active bevel gear rotates, it will drive the three driven bevel gears to rotate, thereby driving the three threaded columns to rotate.

[0013] Furthermore, the outsides of the three threaded columns are all threadedly sleeved with sliding fixing blocks, and the lower ends of the three sliding fixing blocks are all fixedly connected to an upper clamping plate.

[0014] Through the above solution, the rotation of the threaded column will drive the sliding fixed block to move, and then drive the upper clamping plate to move, thereby changing the position between the three upper clamping plates.

[0015] Furthermore, both ends of the two bidirectional screw rods are respectively threadedly sleeved with sliding blocks, and a first lower clamping plate is fixedly connected between two corresponding sliding blocks among the four sliding blocks.

[0016] According to the above solution, since the sliding blocks are threadedly sleeved at both ends of the bidirectional screw rod, the rotation of the bidirectional screw rod will drive the two sliding blocks to move toward or away from each other, thereby changing the distance between the two first lower clamping plates.

[0017] Furthermore, one end of the bidirectional screw rod mounting frame is fixedly connected to a stepper motor, and the output end of the stepper motor extends into the bidirectional screw rod mounting frame and is fixedly connected to one end of the bidirectional screw rod.

[0018] Through the above solution, the bidirectional lead screw is fixedly connected to the output end of the stepper motor, so after the stepper motor is started, the stepper motor will drive the bidirectional lead screw to rotate.

[0019] Furthermore, a threaded rod is threadedly connected to the upper end of the mounting platform, and the threaded rod passes through the mounting platform and is rotatably connected to the second lower clamping plate.

[0020] With the above solution, the threaded rod is rotated during use to move toward the second lower clamping plate. Since the threaded rod and the second lower clamping plate are rotationally connected, the second lower clamping plate will move under the push of the threaded column instead of rotating with the threaded rod.

[0021] Furthermore, two guide columns are slidably connected to the upper end of the mounting platform, and the two guide columns penetrate the mounting platform and are fixedly connected to the surface of the second lower clamping plate.

[0022] Through the above solution, the two guide columns can ensure that the second lower clamping plate always moves at a level during the movement process.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] The spiral bevel gear processing fixture is connected to an electric turntable mounting plate by rotation at the upper end of a base plate, and an electric cylinder is fixedly connected to the upper end of the base plate. Then, the telescopic end of the electric cylinder is fixedly connected to a connecting frame, and the lower end of the connecting frame is fixedly connected to the surface of the electric turntable mounting plate. At the same time, an electric turntable is fixedly connected to the upper end of the electric turntable mounting plate, and then the workbench is fixedly connected to the upper end of the electric turntable. When it is necessary to process the gear at different angles, the electric cylinder is started, and the telescopic end of the electric cylinder will drive the connecting frame to move up and down, thereby driving one side of the electric turntable mounting plate to move up and down. At the same time, because the electric turntable mounting plate and the base plate are rotationally connected, the up and down movement of one side of the electric turntable mounting plate will change the structural inclination angle of the electric turntable mounting plate and the upper end of the electric turntable mounting plate. At the same time, the electric turntable is started. Because the upper end of the electric turntable is fixedly connected to the workbench, the electric turntable will drive the workbench to rotate, thereby changing the horizontal angle of the gear fixed at the upper end of the workbench, which can meet the work of processing gears at different angles and has a wide range of applications.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] See also Figure 2 and Figure 3 The upper end of the upper fixing plate 14 is fixedly connected to a second servo motor 15, the output end of the second servo motor 15 passes through the upper fixing plate 14 and is fixedly connected to the active bevel gear 20, the output end of the second servo motor 15 is fixedly connected to the active bevel gear 20, so starting the second servo motor 15 will drive the active bevel gear 20 to rotate, the lower end of the upper fixing plate 14 is fixedly connected to three threaded column mounting brackets 16, the three threaded column mounting brackets 16 are rotatably connected to the inside of the threaded column 25, and one end of the three threaded columns 25 passes through the threaded column mounting brackets The frame 16 is fixedly connected with a driven bevel gear 19, and the three driven bevel gears 19 are all meshed with the active bevel gear 20. When the active bevel gear 20 rotates, the three driven bevel gears 19 are driven to rotate, thereby driving the three threaded columns 25 to rotate. The outer parts of the three threaded columns 25 are all threadedly sleeved with sliding fixed blocks 17, and the lower ends of the three sliding fixed blocks 17 are fixedly connected with upper clamping plates 18. The rotation of the threaded column 25 will drive the sliding fixed block 17 to move, and then drive the upper clamping plate 18 to move, thereby changing the position between the three upper clamping plates 18.

[0034] See also Figure 1, sliding blocks 10 are respectively threadedly sleeved on both ends of the two bidirectional screw rods 9, and a first lower clamping plate 24 is fixedly connected between two corresponding sliding blocks 10 among the four sliding blocks 10. Because the sliding blocks 10 are threadedly sleeved on both ends of the bidirectional screw rod 9, the rotation of the bidirectional screw rod 9 will drive the two sliding blocks 10 to move toward or oppositely, thereby changing the distance between the two first lower clamping plates 24. A stepper motor 11 is fixedly connected to one end of the bidirectional screw rod mounting frame 8, and the output end of the stepper motor 11 extends into the bidirectional screw rod mounting frame 8 and is fixedly connected to one end of the bidirectional screw rod 9. The bidirectional screw rod 9 is fixedly connected to the output end of the stepper motor 11, so after starting the stepper motor 11, the stepper motor 11 will drive the bidirectional screw rod 9 to rotate.

[0035] See also Figure 1 and Figure 4 The upper end of the mounting platform 7 is threadedly connected with a threaded rod 21, which passes through the mounting platform 7 and is rotatably connected to the second lower clamping plate 23. During use, the threaded rod 21 is rotated to move the threaded rod 21 in the direction of the second lower clamping plate 23. Because the threaded rod 21 and the second lower clamping plate 23 are rotatably connected, the second lower clamping plate 23 will move under the push of the threaded rod 21 instead of rotating with the threaded rod 21. The upper end of the mounting platform 7 is slidably connected with two guide columns 22, which pass through the mounting platform 7 and are fixedly connected to the surface of the second lower clamping plate 23. The two guide columns 22 can ensure that the second lower clamping plate 23 always moves at a level during the movement.

[0036] When the gears are to be machined at different angles, the electric cylinder 5 is started, and the telescopic end of the electric cylinder 5 drives the connecting frame 6 to move up and down, thereby driving one side of the electric turntable mounting plate 2 to move up and down. At the same time, because the electric turntable mounting plate 2 is rotatably connected to the base plate 1, the up and down movement of one side of the electric turntable mounting plate 2 will change the structural inclination angle of the electric turntable mounting plate 2 and the upper end of the electric turntable mounting plate 2. At the same time, the electric turntable 3 is started, because the upper end of the electric turntable 3 is fixedly connected to the workbench 4, the electric turntable 3 will drive the workbench 4 to rotate, thereby changing the horizontal angle of the gear fixed at the upper end of the workbench 4, which can meet the work of machining gears at different angles, and has a wide range of applications.

[0037] It should be noted that the interior of the module 12 is composed of a screw and a slide, so the rotation of the first servo motor 13 will drive the screw inside the module 12 to rotate, thereby driving the slide to move up and down, and then change the position of the upper fixed plate 14.

[0038] The working principle of the above embodiment is:

[0039] First, place the gear on the upper end of the workbench 4, and then start the first servo motor 13. The interior of the module 12 is composed of a screw and a slide, so the rotation of the first servo motor 13 will drive the screw inside the module 12 to rotate, thereby driving the slide to move up and down, and then change the position of the upper fixed plate 14 until the three upper clamping plates 18 move to the outer wall of the upper end of the gear, and then start the second servo motor 15. The second servo motor 15 will drive the active bevel gear 20 to rotate. When the active bevel gear 20 rotates, it will drive the three driven bevel gears 19 to rotate, thereby driving the three threaded columns 25 to rotate. The rotation of the threaded column 25 will Drive the sliding fixed block 17 to move, and then drive the upper clamping plate 18 to move, thereby changing the position between the three upper clamping plates 18 to fix the upper end of the gear, and then start the stepping motor 11. The bidirectional screw rod 9 is fixedly connected to the output end of the stepping motor 11, so after starting the stepping motor 11, the stepping motor 11 will drive the bidirectional screw rod 9 to rotate. Because the sliding block 10 is threadedly sleeved on both ends of the bidirectional screw rod 9, the rotation of the bidirectional screw rod 9 will drive the two sliding blocks 10 to move toward or oppositely, thereby changing the distance between the two first lower clamping plates 24 until the first lower clamping plate 24 is fixed to the lower end of the gear.
