Technical Field
[0001] This utility model relates to the field of metal drive shaft processing technology, specifically a keyway processing device for metal drive shaft components. Background Technology
[0002] A metal driveshaft is a shaft that connects two rotating objects, primarily used to transmit power and torque. It is widely used in automobiles, aircraft, construction machinery, and ships. It typically consists of a shaft body, a shaft end, a coupling, and supporting components. The shaft body is the main part that transmits power and torque, and is usually cylindrical or rod-shaped. The shaft end is used to connect other equipment or transmission devices.
[0003] Regarding the above and existing related technologies: When producing metal drive shafts, it is necessary to open keyways on the metal drive shafts. This is done by using CNC milling machines. However, the fixing structure of traditional milling machines lacks the ability to fix the drive shafts properly during machining. When the specifications of the machined drive shafts vary greatly, mismatch problems can easily occur. Therefore, to address the above problems, a keyway machining device for metal drive shaft components is proposed. Utility Model Content

A driving part is fixedly connected to the upper surface of the machine body, and a processing part is fixedly connected to the surface of the driving part. A base is slidably connected to the surface of the machine body. A fixing device is provided on the upper surface of the base. The fixing device includes a pad. The bottom end of the pad is fixedly connected to the upper surface of the base. Two top blocks are inserted into the inner surface of the pad. Two fixing blocks are fixedly connected to the upper surface of the pad. A threaded post is provided on the inner wall of the fixing block. The threaded post is located on one side of the top block. Rotating the threaded post allows it to rotate on the inner wall of the fixing block. The threaded post presses against the surface of the transmission shaft, and then the transmission shaft is processed. By setting the pad, top blocks, fixing blocks, and threaded post, the transmission shaft can be fixed.
[0006] Preferably, two connecting blocks are fixedly connected to both sides of the pad. The connecting blocks and the inner wall of the base are threaded with positioning pins. After the pad is placed in a suitable position, the positioning pins are rotated to the inner surfaces of the connecting blocks and the base. The position of the pad can be fixed by setting the positioning pins and connecting blocks.
[0007] Preferably, the inner walls of the pad and the top block are threaded together with a fixing pin. After the top block is inserted into the inner surface of the pad, the fixing pin is rotated to the inner wall of the pad and the top block, and the fixing pin can restrict the position of the top block.
[0008] Preferably, a top plate is fixedly connected to the side wall of the threaded column, and the top plate rests on the surface of the drive shaft, which can reduce the random movement of the drive shaft.
[0009] Preferably, the side plate of the top block is fixedly connected with a locking block. When the drive shaft moves, the drive shaft will fit against the locking block, and the locking block can increase the contact area with the drive shaft.
[0010] Preferably, both sides of the pad are provided with blocking devices. The blocking device includes a locking strip, the side wall of the locking strip is fixedly connected to the side wall of the pad, the surface of the locking strip is fitted with an inclined plate, and the side wall of the inclined plate is fixedly connected with a side plate. The debris will be blocked by the inclined plate and the side plate. By setting the locking strip, the inclined plate and the side plate, the situation of debris flying to other places can be reduced.
[0011] Preferably, a connecting strip is fixedly connected to the side wall of the inclined plate, and a magnetic strip is fixedly connected to the side wall of the connecting strip. The side wall of the magnetic strip and the side wall of the card strip are magnetically attracted to each other, and the magnetic strip is attracted to the surface of the card strip. By setting the connecting strip and the magnetic strip, the inclined plate can be fixed to the surface of the card strip.
[0012] The advantages of this utility model are:
[0013] 1. When processing a metal drive shaft, this utility model involves placing a pad on a suitable position on the base surface, rotating the positioning pin to the inner surface of the connecting block and the base, inserting the top block adapted to the metal drive shaft being processed into the inner surface of the pad, rotating the fixing pin to the inner wall of the pad and the top block, then attaching the drive shaft to the top block, rotating the threaded column to rotate on the inner wall of the fixing block, causing the threaded column to move the top plate, which presses against the surface of the drive shaft, and the drive shaft to fit against the surface of the clamping block. The drive shaft is then processed by the processing unit. By setting up the entire device, the drive shaft can be easily fixed, and it can also accommodate more specifications of drive shafts, reducing the situation where the fixing mechanism is not compatible with the drive shaft.
[0014] 2. When using the pad, the inclined plate is pushed to fit onto the surface of the card strip. When the inclined plate moves, it will drive the side plate and connecting strip to move. The connecting strip will drive the magnetic strip to move. The magnetic strip is magnetically attracted to the side wall of the card strip. During processing, the flying debris will be blocked by the inclined plate and the side plate. By setting the entire device, the flying debris can be blocked, thereby reducing the tediousness of cleaning. Attached Figure Description
