Description

Technical Field

[0001] This utility model relates to the field of radial milling machine technology, specifically to a radial milling machine for producing automobile axles. Background Technology

[0002] The axle is an important component of the automobile chassis and a key transmission component connecting the wheels and the vehicle's suspension system. The axle often needs to be processed by a radial milling machine, which is one of the key processing steps from the blank to the finished product. In existing technology, when using a radial milling machine to fix automotive axles (such as drive shafts and transmission shafts) to components such as gears and flanges via a "key connection", the automotive axle body is designed with 1-2 rectangular keyways. The automotive axle to be processed is fixed to the worktable with a vise. The radial milling machine is started, and the rotation of the spindle drives the milling cutter to rotate. At the same time, the worktable moves in three directions and the radial arm rotates, causing relative motion between the milling cutter and the workpiece, thereby realizing the cutting of the workpiece and processing the keyways of the automotive axle. However, for the processing of automotive axle workpieces, the fixation effect of the vise is not good, resulting in unstable workpiece clamping and errors in the cutting of the keyways. Utility Model Content

[0003] To overcome the above-mentioned defects, the present invention provides a radial arm milling machine for producing automobile axles, which solves the technical problem in the prior art where the workpiece is not well fixed by a flat-jaw vise, resulting in unstable workpiece clamping and errors in the cutting of keyways.

[0004] According to one aspect, at least one embodiment of the present invention provides a radial milling machine for producing automobile axles, comprising a radial milling machine body, the radial milling machine body including a worktable with multiple T-slots formed thereon, and further including a fixed seat, a movable plate and a clamping plate. The bottom end of the fixed seat is fixedly connected to the T-slots, the fixed seat is slidably disposed on the worktable, and the fixed seat is detachably connected to the worktable by bolts. The fixed seat has an arc-shaped groove and a cavity. The movable plate is longitudinally movable within the cavity by a lifting mechanism. Two sets of clamping plates are symmetrically and movably disposed on the movable plate by the movable mechanism, each set of clamping plates including multiple clamping plates.

[0005] Preferably, the lifting mechanism includes a lifting plate, a first threaded rod, a drive shaft, and a first knob. A sliding groove is provided in the fixed base. The lifting plate is slidably disposed in the sliding groove and fixedly connected to the moving plate. The first threaded rod is rotatably disposed in the sliding groove, passes through the lifting plate, and is threadedly connected to the lifting plate.

One end of the drive shaft is coaxially fixedly connected to one end of the first threaded rod, and one end of the first knob is coaxially fixedly connected to the other end of the drive shaft.

[0006] Furthermore, the moving mechanism includes a drive plate, a connecting plate, and a drive assembly. The bottom end of the clamping plate is fixedly connected to the drive plate, and the bottom end of each set of clamping plates is fixedly connected to the connecting plate. The moving plate has two moving slots that cooperate with the connecting plate, and the drive assembly is disposed on the moving plate to drive the two connecting plates to move.

[0007] Furthermore, the drive assembly includes a second threaded rod, a rotating shaft, a rotating rod, and a second knob. The second threaded rod is rotatably disposed within the moving groove. The two second threaded rods are respectively threadedly connected to the two connecting plates. The rotating shaft is rotatably disposed within the moving plate. Both ends of the rotating shaft are coaxially and fixedly connected to one end of each of the two second threaded rods. One end of the rotating rod is coaxially and fixedly connected to the other end of one of the second threaded rods. One end of the second knob is coaxially and fixedly connected to the other end of the rotating rod.

[0010] Based on the aforementioned scheme, in order to drive the two connecting plates to move towards each other during the rotation of the second knob, the threads of the two second threaded rods are rotated in opposite directions.

[0011] Furthermore, in order to enable the movable plate to drive the rotating rod to move longitudinally within the fixed seat, the fixed seat is provided with a slot that cooperates with the rotating rod.

[0012] The beneficial effects of this utility model are as follows: In this utility model, the car axle is placed on the arc-shaped groove by the cooperation of the fixed seat, the movable plate, the lifting mechanism, the clamping plate and the movable mechanism. By rotating the first knob, multiple clamping plates are driven to move longitudinally, so that the height of the clamping plates can be adjusted and car axles of different diameters can be clamped and fixed.

[0022] like Figures 1-5As shown, it illustrates a rocker arm milling machine for producing automobile axles in one embodiment of the present invention, including a rocker arm milling machine body 1, the rocker arm milling machine body 1 including a worktable 2, the worktable 2 having multiple T-shaped slots 3, and also including a fixed seat 4, a moving plate 7 and a clamping plate 9; like Figure 2 As shown, a T-shaped plate 5 is fixedly connected to the bottom end of the fixed seat 4. The fixed seat 4 is slidably disposed on the worktable 2. The fixed seat 4 is detachably connected to the worktable 2 by bolts. An arc-shaped groove 6 is provided on the fixed seat 4. The arc-shaped groove 6 is used to place the automobile axle to be ground. The diameter of the arc-shaped groove 6 is relatively large, so it can hold automobile axles of different diameters. like Figure 4 As shown, the fixed base 4 has a cavity 8. The movable plate 7 is longitudinally movable within the cavity 8 via a lifting mechanism. The lifting mechanism includes a lifting plate 10, a first threaded rod 12, a drive shaft 13, and a first knob 14. The fixed base 4 has a sliding groove 11. The lifting plate 10 is slidably disposed within the sliding groove 11 and fixedly connected to the movable plate 7. The first threaded rod 12 is rotatably disposed within the sliding groove 11, and the first threaded rod 12 passes through the lifting plate 10 and is threaded onto the lifting plate 10. The drive shaft 13 is rotatably mounted in the fixed seat 4. One end of the drive shaft 13 is coaxially fixedly connected to one end of the first threaded rod 12. One end of the first knob 14 is coaxially fixedly connected to the other end of the drive shaft 13. By rotating the first knob 14, the first knob 14 drives the drive shaft 13 to rotate, the drive shaft 13 drives the first threaded rod 12 to rotate, the first threaded rod 12 drives the lifting plate 10 to move longitudinally along the inner wall of the slide groove 11, and the lifting plate drives the moving plate 7 to move longitudinally along the inner side wall of the cavity 8. like Figure 3 and Figure 5As shown, two sets of clamping plates 9 are symmetrically and movably arranged on the movable plate 7 via a moving mechanism. Each set of clamping plates 9 includes multiple clamping plates 9. To securely clamp the car axle, one end of each clamping plate 9 has a V-shaped groove 22. The moving mechanism includes a drive plate 15, a connecting plate 16, and a drive assembly. The bottom end of each clamping plate 9 is fixedly connected to the drive plate 15, and the bottom end of each set of clamping plates 9 is fixedly connected to the connecting plate 16. The movable plate 7 has two moving grooves 17 that cooperate with the connecting plate 16. To ensure that the clamping plates 9 and the connecting plate 16 can be securely clamped, the moving plate 7 provides a V-shaped groove 22 for the car axle. The drive plate 15 moves on the fixed base 4. The fixed base 4 has a through groove 23 that cooperates with the clamping plate 9 and the drive plate 15. The moving groove 17 communicates with the through groove 23. The width of the through groove 23 and the moving groove 17 is the same. By rotating the first knob 14, the moving plate 7 is driven to move longitudinally. The moving plate 7 drives the moving mechanism and multiple clamping plates 9 to move longitudinally. This can adjust the height of the clamping plates 9 so that the center of the V-shaped groove 22 is on the same horizontal line as the axis of the car axle placed on the arc groove 6. This can clamp and fix car axles of different diameters. It should be added that after adjusting the position of the movable plate 7, measuring tools such as calipers can be used to measure whether the clamping plate 9 is accurately aligned with the car axle placed on the arc groove 6; The driving assembly is mounted on the movable plate 7 to drive the two connecting plates 16 to move. The driving assembly includes a second threaded rod 18, a rotating shaft 19, a rotating rod 20, and a second knob 21. The second threaded rod 18 is rotatably disposed within the movable groove 17. The two second threaded rods 18 are threadedly connected to the two connecting plates 16 respectively. To drive the two connecting plates 16 to move towards each other during the rotation of the second knob 21, the threads of the two second threaded rods 18 have opposite directions. The rotating shaft 19 is rotatably disposed within the movable plate 7. Both ends of the rotating shaft 19 are coaxially and fixedly connected to one end of each of the two second threaded rods 18. One end of the rotating rod 20 is coaxially and fixedly connected to the other end of one of the second threaded rods 18. To allow the movable plate 7 to drive the rotating rod 20 to move longitudinally within the fixed seat 4, The fixed base 4 has a slot 24 that mates with the rotating rod 20. One end of the second knob 21 is coaxially fixedly connected to the other end of the rotating rod 20. By rotating the second knob 21, the second knob 21 drives the rotating rod 20 to rotate. The rotation of the rotating rod 20 drives a second threaded rod 18 to rotate. The second threaded rod 18 drives the rotating shaft 19 to rotate. The rotating shaft 19 drives another second threaded rod 18 to rotate. The two second threaded rods 18 rotate simultaneously and drive the two connecting plates 16 to move towards each other. The two connecting plates 16 drive multiple sets of drive plates 15 to move towards each other. The multiple drive plates 15 drive multiple clamping plates 9 to move towards each other. The V-groove 22 on the clamping plate 9 firmly clamps the car axle. The threaded engagement between the threaded rod and the threaded groove has self-locking properties, which can keep the moving plate 7 and the connecting plate 16 stable and prevent displacement during the grinding process. Working principle: When fixing the automobile axle to be ground, the radial milling machine for producing automobile axles places the axle on the arc-shaped groove 6. By rotating the first knob 14, the moving plate 7 is driven to move longitudinally. The moving plate 7 drives the moving mechanism and multiple clamping plates 9 to move longitudinally, thus adjusting the height of the clamping plates 9 so that the center of the V-shaped groove 22 is on the same horizontal line as the axis of the automobile axle placed on the arc-shaped groove 6. Then, the second knob 21 is rotated, which drives the rotating rod 20 to rotate. The rotation of the rotating rod 20 drives a second threaded rod 18 to rotate. 8 drives the rotating shaft 19 to rotate, the rotating shaft 19 drives another second threaded rod 18 to rotate, the two second threaded rods 18 rotate simultaneously and drive the two connecting plates 16 to move towards each other respectively, the two connecting plates 16 drive multiple sets of drive plates 15 to move towards each other respectively, the multiple drive plates 15 drive multiple clamping plates 9 to move towards each other, the V-groove 22 on the clamping plate 9 firmly clamps the car axle, the threaded engagement between the threaded rod and the threaded groove has self-locking property, which can keep the moving plate 7 and the connecting plate 16 stable, avoid displacement during the grinding process, and have a good fixing effect on the car axle; It should be added that when grinding the automobile axle, the grinding is performed on the position of the automobile axle on one side of the fixed seat 4. The operating space of the automobile axle on the fixed seat 4 is too small, making it difficult for the milling cutter to cooperate with the rocker arm to perform the grinding operation.
