Description

Technical Field

[0001] This utility model relates to the field of automotive drive shaft processing, specifically to a cutting device for automotive drive shaft production. Background Technology

[0002] With economic progress, people's demand for automobiles has gradually increased, so the automobile industry has also developed. In the automobile manufacturing process, it is necessary to manufacture the whole parts separately and then assemble them. Among them, the engine is a major component of the automobile, and the drive shaft is an essential component inside the engine. When producing the automobile drive shaft, cutting equipment is required to cut the automobile drive shaft.

[0003] When the cutting equipment for producing automotive drive shafts is in use, the machine tool clamps the rough blank of the drive shaft, and then drives the clamping assembly to rotate to cut one section. After the cutting of one section is completed, the automated gripper changes the position of the drive shaft that has been machined at one end, and the above steps are repeated to cut the other end.

[0004] However, the cutting equipment used in the production of automotive drive shafts today processes both ends of the drive shaft, requiring the drive shaft to be repositioned, resulting in slower overall production efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, a cutting device for producing automotive drive shafts is provided. This technical solution solves the problem mentioned in the background art that machining both ends of the automotive drive shaft requires repositioning the automotive drive shaft, resulting in slow overall production efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A cutting device for producing automotive drive shafts includes a machining table with a cavity in the middle. Mounting plates are slidably connected to both ends of the top of the machining table. A second rotary motor is mounted on one end of one set of mounting plates. A connecting rod is fixed between the two sets of mounting plates. An outer bushing is fixed to the end of the connecting rod. A clamping cylinder is rotatably connected inside the outer bushing. Bearing rings are rotatably connected to both ends of the outer side of the clamping cylinder. Pneumatic sliders are slidably connected to both ends of the inner wall of the clamping cylinder. A clamping plate is connected to the end of the pneumatic slider. A locking plate is rotatably connected to the top and bottom of the clamping plate. A transmission rod penetrating into the outer bushing is connected to the output end of the second rotary motor. A bevel gear is fixedly connected to the end of the transmission rod. A conical gear ring meshing with the bevel gear is fixedly connected to the outer side of the clamping cylinder and inside the outer bushing.

[0008] Preferably, a first rotary motor is installed on both sides of the top of the processing table, and a sliding groove is provided on the inner wall of both sides of the processing table. The output end of the first rotary motor is connected to a screw that penetrates into the sliding groove. The outer side of the screw is connected to a slider that cooperates with the sliding groove through a threaded connection. A cutting head is fixed on one side of the slider.

[0009] Preferably, there are two sets of cutting heads, and the two sets of cutting heads are detachably fixedly connected to the slider through a flange.

[0010] Preferably, the clamping cylinder has air chambers at both ends, the air chambers are connected to the bearing ring, the air chambers are connected to the pneumatic slider, and the bearing ring has an air inlet at the top.

[0011] Preferably, the number of pneumatic sliders is three sets, and the three sets of pneumatic sliders are symmetrical about the dot.

[0012] Preferably, electric push rods are installed at both ends of the top of the processing table, and the output end of the electric push rods is connected to the mounting plate.

[0013] Preferably, the bottom limiting block of the mounting plate and both ends of the top of the processing table are provided with limiting grooves that cooperate with the limiting block.

[0014] Preferably, there are two sets of clamping plates, and a spring is installed at the rotatable connection between the two sets of clamping plates and the clamping plate.

[0015] Compared with the prior art, this utility model provides a cutting device for producing automotive drive shafts, which has the following advantages: By placing the drive shaft inside the clamping cylinder, and then injecting gas into the air inlet, the pneumatic slider is activated to move inward. The pneumatic slider drives the clamping plate to move inward, and at this time, the clamping plate drives the chuck plate to move inward. The chuck plate gradually contacts the drive shaft while rotating, adapting to drive shafts of different diameters, thus facilitating the clamping of the drive shaft and exposing both ends of the drive shaft. Simultaneously, depending on the shape of the automotive drive shaft, a first set of rotary motors can be started individually or simultaneously. The rotary motor controls the power of two sets of first rotary motors, thereby controlling the downward or upward movement rate of two sets of cutting heads. It can simultaneously cut both ends of the drive shaft, or activate the electric push rod to drive the clamping cylinder to move horizontally, thereby changing the distance between the drive shaft and the cutting head to adapt to the cutting width of the drive shaft. When only one set of first rotary motors is activated, a set of cutting heads can be positioned at the bottom of the cavity, so that the cutting head does not contact the drive shaft, which can achieve the purpose of machining one end of the drive shaft separately. This adapts to the automatic gripper flipping the drive shaft, simplifies the operation steps, and improves efficiency. Attached Figure Description

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Example 1

[0024] Please refer to Figures 1-4 As shown, a cutting device for producing automotive drive shafts includes a machining table 1. A cavity 7 is provided in the middle of the interior of the machining table 1. Mounting plates 9 are slidably connected to both ends of the top of the machining table 1. A second rotary motor 11 is mounted on one end of a set of mounting plates 9. A connecting rod 8 is fixed between the two sets of mounting plates 9. An outer bushing 10 is fixed to the end of the connecting rod 8. A clamping cylinder 15 is rotatably connected inside the outer bushing 10. Bearing rings 16 are rotatably connected to both ends of the outer side of the clamping cylinder 15. Pneumatic sliders 19 are slidably connected to both ends of the inner wall of the clamping cylinder 15. A clamping plate 18 is connected to the end of the pneumatic slider 19. A clamping plate 20 is rotatably connected to the top and bottom ends of the clamping plate 18. A transmission rod 12 that penetrates into the interior of the outer bushing 10 is connected to the output end of the second rotary motor 11. A bevel gear 14 is fixedly connected to the end of the transmission rod 12. A bevel gear ring 13 that meshes with the bevel gear 14 is fixedly connected to the outer side of the clamping cylinder 15 and inside the outer bushing 10.

[0025] In this embodiment, the second rotary motor 11 is started to drive the transmission rod 12 to rotate, the transmission rod drives the bevel gear 14 to rotate, the bevel gear 14 drives the bevel gear ring 13 to rotate, the bevel gear ring 13 drives the clamping cylinder 15 to rotate, and when the clamping cylinder 15 rotates, it cooperates with the cutting head 5 to complete the cutting of the drive shaft.

[0026] Example 2

[0027] Please refer to Figure 1 As shown, a first rotary motor 2 is installed on both sides of the top of the processing table 1. The inner walls of both sides of the processing table 1 are provided with slide grooves 21. The output end of the first rotary motor 2 is connected to a screw 3 that passes through the slide groove 21. The outer side of the screw 3 is connected to a slider 4 that cooperates with the slide groove 21 through a threaded connection. A cutting head 5 is fixed on one side of the slider 4. There are two sets of cutting heads 5. The two sets of cutting heads 5 are detachably fixedly connected to the slider 4 through a flange.

[0028] In this embodiment, the first rotary motor 2 is started to drive the screw 3 to rotate. Under the action of the slider 4 and the slide groove 21, the screw moves, and the slider 4 drives the cutting head 5 to rise and fall, changing the cutting depth of the drive shaft. When the slider 4 drives the cutting head 5 to the lowest end, the cutting head 5 does not contact the drive shaft, thus achieving the purpose of not processing one end of the drive shaft and processing the other end. The first rotary motor 2 can be started at the same time. The rotation speed of the first rotary motor 2 can be controlled by the data operator through programming, so as to achieve the purpose of cutting different depths at both ends of the drive shaft. At the same time, the flange can replace the cutting head, and a suitable cutting head can be selected to adapt to the drive shaft of different lengths.

[0031] In this embodiment, air is introduced through the air inlet 17, and the three sets of pneumatic sliders 19 move inward to clamp the drive shaft. At the same time, when the clamping plate 18 gradually approaches the drive shaft, the clamping plate 20 releases the drive shaft and gradually rotates to clamp the drive shaft. The spring is provided so that the clamping plate 20 will not sag when not subjected to external force, thus preventing the clamping plate 20 from failing to contact the drive shaft.

[0032] Example 4

[0033] Please refer to Figure 1 As shown, electric push rods 6 are installed at both ends of the top of the processing table 1. The output end of the electric push rod 6 is connected to the mounting plate 9. The bottom limit block of the mounting plate 9 and the two ends of the top of the processing table 1 are provided with limit grooves that cooperate with the limit blocks.

[0034] In this embodiment, the electric push rod 6 is activated, causing the limiting block to slide in the limiting groove, thereby changing the position of the mounting plate 9, which in turn changes the position of the clamping cylinder 15, thereby driving the drive shaft to move horizontally, which can change the width of the cutting head 5 cutting the drive shaft.
