Description

Technical Field

[0001] The utility model relates to the field of drilling processing of transmission shafts, and specifically relates to a drilling processing device for transmission shafts. Background Art

[0002] A transmission shaft is a shaft for transmitting kinetic energy. When a transmission shaft is produced and manufactured, it often needs to be drilled, and a drilling device is required.

[0003] Currently, when a drilling device drills a transmission shaft, it will clamp the outer ring of the transmission shaft to facilitate subsequent drilling. After clamping, when the transmission shaft contacts the drill, its surface may slightly shake or rotate, which may cause the position of the drill hole to deviate and reduce the accuracy. Summary of the Utility Model

[0004] In order to solve the above problems, the purpose of the utility model is to provide a drilling processing device for transmission shafts to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model proposes a drilling processing device for transmission shafts, which includes a bottom plate. A base plate is fixedly installed on the top of the bottom plate, and two placing plates are fixedly installed on the top of the base plate. On one side of the top of the two placing plates, a first clamping plate is fixedly installed;

[0006] A clamping mechanism is arranged on the top of the placing plate, and the clamping mechanism includes a U-shaped frame, an arc-shaped clamping plate, a spring column and an inclined plate. Two spring columns are fixedly installed on the top of each of the two placing plates. The top ends of two of the spring columns are fixedly installed with U-shaped frames. An arc-shaped clamping plate is fixedly installed at the bottom of the two U-shaped frames. Inclined plates slidably connected to the placing plates are fixedly installed on both sides of the bottom of the two U-shaped frames.

[0007] In one example, chutes are opened on the other side of the two placing plates, and sliders are slidably connected to the inner walls of the two chutes.

[0008] In one example, second clamping plates are fixedly installed on the tops of the two sliders.

[0009] In one example, electric cylinders are fixedly installed on the inner walls of the two chutes, and the output shafts of the two electric cylinders are fixedly connected to the sliders.

[0010] In one example, a support plate is fixedly installed on the top of the bottom plate, and a mounting plate is fixedly installed on the top of the support plate.

[0011] In one example, two drillers are fixedly installed on the bottom of the mounting plate. The output shafts of the two drillers are inserted through the U-shaped frames, and a limiting plate connected to the U-shaped frame is fixedly installed on the outer circle of the output shafts of the drillers.

[0012] A drilling processing device for a transmission shaft proposed by the present utility model can bring the following beneficial effects:

[0013] 1. For the drilling processing device for a transmission shaft, starting the drill will drive the limiting plate to move downward, thereby squeezing the U-shaped frame downward, and driving the arc-shaped clamping plate to descend, which can clamp the transmission shaft during drilling, avoid the rotation of the transmission shaft during drilling, and thus can firmly clamp it, facilitating subsequent drilling.

[0014] 2. For the drilling processing device for a transmission shaft, starting the electric cylinder drives the slider to move in the chute, which will drive the second clamping plate to move, clamp the side corresponding to the first clamping plate of the transmission shaft, and clamp the transmission shaft, facilitating its stability and subsequent drilling.

[0021] In order to more clearly illustrate the overall concept of the present utility model, the following is a detailed description by way of examples in conjunction with the accompanying drawings of the specification.

[0022] As Figures 1 to 4 shown, an embodiment of the present utility model provides a drilling processing device for a transmission shaft, including a bottom plate 1, a substrate 2 is fixedly installed on the top of the bottom plate 1, two placement plates 3 are fixedly installed on the top of the substrate 2, and a first clamping plate 7 is fixedly installed on one side of the top of the two placement plates 3;

[0023] A clamping mechanism is provided at the top of the placement plate 3, and the clamping mechanism includes a U-shaped frame 4, an arc-shaped clamping plate 5, a spring column 6, and an inclined plate 8. Two spring columns 6 are fixedly installed at the top of each of the two placement plates 3. The top ends of two of the spring columns 6 are fixedly installed with a U-shaped frame 4. The bottom of the two U-shaped frames 4 is fixedly installed with an arc-shaped clamping plate 5. Both sides of the bottom of the two U-shaped frames 4 are fixedly installed with inclined plates 8 that are slidably connected to the placement plate 3.

[0024] Specifically, sliding grooves 15 are provided on the other side of each of the two placement plates 3. Sliders 14 are slidably connected to the inner walls of the two sliding grooves 15. The sliders 14 are slidably connected through the sliding grooves 15, and the sliders 14 fix the second clamping plate 13.

[0025] Specifically, second clamping plates 13 are fixedly installed at the top of the two sliders 14. When drilling a hole in the transmission shaft, the second clamping plates 13 cooperate with the first clamping plate 7 for clamping.

[0026] Specifically, electric cylinders 12 are fixedly installed on the inner walls of the two sliding grooves 15. The output shafts of the two electric cylinders 12 are fixedly connected to the sliders 14. The electric cylinders 12 drive the sliders 14 to move, thereby driving the second clamping plates 13 to move.

[0027] Specifically, a support plate 11 is fixedly installed at the top of the bottom plate 1, and a mounting plate 10 is fixedly installed at the top of the support plate 11. The support plate 11 fixes the mounting plate 10, and the mounting plate 10 fixedly installs a drilling device 9.

[0028] Specifically, two drilling devices 9 are fixedly installed at the bottom of the mounting plate 10. The output shafts of the two drilling devices 9 are inserted through the U-shaped frame 4, and a limiting plate 16 that is connected to the U-shaped frame 4 is fixedly installed on the outer ring of the output shaft of the drilling device 9. The output shaft of the drilling device 9 drills a hole in the transmission shaft, and the limiting plate 16 presses down on the U-shaped frame 4.

[0029] Working principle: Place the transmission shaft on the placement plate 3 and connect it to the first clamping plate 7. At this time, start the electric cylinder 12 to drive the slider 14 to move in the sliding groove 15, drive the second clamping plate 13 to move, clamp the side of the transmission shaft corresponding to the first clamping plate 7, and clamp the transmission shaft. Then start the drilling device 9, which will drive the limiting plate 16 to move downward, and squeeze the U-shaped frame 4 downward, which will drive the arc-shaped clamping plate 5 to descend, enabling clamping during drilling of the transmission shaft, thus facilitating drilling by the drilling device 9. After drilling, the limiting plate 16 is separated from the U-shaped frame 4. At this time, under the potential energy of the spring column 6, the U-shaped frame 4 will be driven to return to its initial position, and the arc-shaped clamping plate 5 will be separated from the transmission shaft, facilitating the removal of the transmission shaft.
