Technical Field
[0001] This utility model relates to the field of transmission shaft processing and conveying technology, specifically a chamfering device for transmission shafts. Background Technology
[0002] The drive shaft is a core component of the mechanical transmission system, mainly used to transmit rotational power and torque. The end face of the drive shaft is usually chamfered, so a chamfering device is required. However, the current drive shaft chamfering devices have the following problems: (1) When only one end of the drive shaft needs to be chamfered, only one drive shaft can be chamfered at a time, and it is not possible to chamfer two drive shafts at the same time; when both ends of the drive shaft need to be chamfered, one end is usually chamfered first, and then the other end is chamfered, and it is not possible to chamfer both ends at the same time. (2) When chamfering, water needs to be sprayed onto the chamfered area. Currently, when spraying water, only one end can be sprayed, and it is difficult to adjust the angle and position of the nozzle, making it difficult to adjust the angle and position of the spray. Utility Model Content

The intermediate plate has a positioning mechanism and a water spraying mechanism that simultaneously sprays water to both ends of the positioning mechanism. A water supply mechanism that supplies water to the water spraying mechanism is located on the top of the machine tool. Linear displacement mechanisms are located on both sides of the intermediate plate on the inner back plate of the machine tool, and slides are driven by these linear displacement mechanisms. A first cylinder extending forward is mounted on the slide. The telescopic end of the first cylinder is connected to an L-shaped mounting plate, and a chamfering mechanism is mounted on the mounting plate. The positioning mechanism includes a support platform fixedly connected to the intermediate plate, a positioning cylinder rotatably connected to the support platform via a rotary bearing, a clamping mechanism mounted at both ends of the positioning cylinder, and a drive mechanism mounted on the intermediate plate for driving the positioning cylinder to rotate. The two ends of the positioning cylinder extend to the outer side of the intermediate plate.
[0006] Preferably, the clamping mechanism includes two second cylinders installed on the outer wall of the positioning cylinder opening, and an arc-shaped clamping plate connected to the telescopic ends of the two second cylinders, with the two clamping plates symmetrically arranged inside the positioning cylinder; the driving mechanism includes a first motor installed on the intermediate plate, a first transmission shaft connected to the first motor via a coupling, a first gear fixedly connected to the first transmission shaft, and a second gear fixedly connected to the positioning cylinder, with the first gear meshing with the second gear.
[0007] The above technical solution involves inserting the drive shaft into the positioning cylinder, then controlling the extension of the second cylinder to move the clamping plate to clamp the drive shaft, and then controlling the first motor to work. Through the cooperation of the first gear and the second gear, the positioning cylinder is rotated, thereby driving the drive shaft to rotate.
[0008] Preferably, the water spraying mechanism includes a second motor mounted on the intermediate plate, a rotating shaft rotatably connected to the upper part of the intermediate plate via a rotary bearing, a second drive shaft driven by the second motor, a third gear connected to the second drive shaft, and a fourth gear fixedly connected to the rotating shaft.

A fixing plate is connected to the telescopic end of the fourth cylinder, and a nozzle is mounted on the fixing plate. The water supply mechanism includes a water tank and a water pump mounted on the top of the machine tool.

Through the cooperation of the third and fourth gears, the two third cylinders can rotate simultaneously in opposite directions, thereby adjusting the nozzle angle. The operation of the third cylinders drives the nozzle to move back and forth, thus adjusting its position in the forward and backward direction. The operation of the fourth cylinder drives the nozzle towards the chamfered edge of the drive shaft, bringing it closer to the chamfered edge. The collar design constrains the hose, preventing it from tangling. When water spraying is needed, the control valve is opened, the water pump is started, and water from the tank is delivered to the nozzle through the hose and sprayed out.

The third motor is drivenly connected to one end of the lead screw, the slide is threadedly connected to the lead screw, and the slide is slidably connected to the guide rail.
[0011] The above technical solution controls the operation of the third motor, which drives the lead screw to rotate. During the rotation of the lead screw, the slide moves linearly along the guide rail, thereby adjusting the distance between the chamfering mechanism and the middle plate to adapt to drive shafts of different lengths.
[0012] Preferably, the chamfering mechanism includes a fifth cylinder mounted on a mounting plate, a mounting sleeve connected to the telescopic end of the fifth cylinder, and a blade threadedly connected to the mounting sleeve, the lower end of which is a bevel.
[0013] The above technical solution controls the operation of the fifth cylinder, which drives the blade plate to rise and fall, thereby adjusting the height of the blade plate so that the inclined surface of the blade plate can abut against the end face of the drive shaft to adapt to drive shafts of different diameters.
[0014] Preferably, a control box is provided on one side of the machine tool, and a controller is provided inside the control box. The control box is equipped with a start button, a control button and a display. The first motor, the second motor, the third motor, the first cylinder, the second cylinder, the third cylinder, the fourth cylinder, the fifth cylinder, the water pump, the control valve, the display, the start button and the control button are all electrically connected to the controller.

[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] (1) When it is necessary to chamfer the end faces of two drive shafts, both drive shafts are inserted into the positioning cylinder, with the chamfered portion of the drive shaft located outside the positioning cylinder. Then, the drive shafts are clamped by the clamping mechanism, and the chamfering mechanisms on both sides are used to chamfer the ends of the two drive shafts respectively.
