[0002] A transmission shaft is an important component for transmitting power in an automotive transmission system. Its function is to transmit the power of the engine to the wheels together with the gearbox and the drive axle, so as to make the vehicle generate driving force. During the production process of the transmission shaft, boring processing needs to be carried out on the connecting holes at the fork end of the shaft to facilitate the mutual installation of components. When boring the connecting holes, in order to ensure the accuracy of the boring processing, the overall fork needs to be fixed by a fixing device. However, when the existing fixing device is in use, its clamping stability for the fork is poor, and the operation process is time-consuming and laborious, seriously affecting the production and processing efficiency of the fork. Therefore, in order to solve the above problems, it is necessary to develop a fixing device for boring processing of a transmission shaft fork that is convenient to operate and use and has stable and reliable clamping.

[0014] The present utility model will be further described below with reference to the drawings.

[0015] Embodiment: As Figure 1 , Figure 2 , Figure 3As shown in the figure, a fixing device for boring a transmission shaft fork includes a mounting base plate 1, a limiting pressing plate 2, and an electric push rod 3. The mounting base plate 1 is horizontally arranged as a whole. A chute 11 is horizontally arranged at the left end of its upper surface. A middle support plate 4 is vertically and fixedly arranged in the middle of the upper surface. A baffle 5 is vertically and fixedly arranged at the right end of the upper surface. A placing through groove 41 is vertically arranged in the middle of the upper end of the middle support plate 4. A limiting groove 51 is arranged on the left side surface of the baffle 5. A push plate 52 is horizontally slidably arranged inside the limiting groove 51. An elastic member 53 is horizontally and fixedly arranged between the side surface of the push plate 52 and the groove bottom surface of the limiting groove 51. The limiting pressing plate 2 is vertically arranged at the left end of the upper surface of the mounting base plate 1. A slider is fixedly arranged below it and is slidably connected to the chute 11 through the slider. Pressing blocks 21 are fixedly arranged in the middle of the upper end and the middle of the lower end of the right side surface respectively. A V-shaped groove 22 is arranged in the middle of the right side surface of the pressing block 21. There are two electric push rods 3, which are respectively horizontally and fixedly arranged at the front end and the rear end between the middle support plate 4 and the limiting pressing plate 2.

[0016] The elastic member 53 is composed of a guiding telescopic rod and a spring sleeved outside the guiding telescopic rod. Card slots are horizontally arranged at the upper end and the lower end of the inner surface of the limiting groove 51. Clamping blocks that are matched with the card slot structure are fixedly arranged at the upper end and the lower end of the push plate 52 respectively. A reinforcing rod 6 is horizontally and fixedly arranged at the lower end between the middle support plate 4 and the baffle 5. The reinforcing rod 6 can be used to increase the connection stability between the middle support plate 4 and the baffle 5. Mounting holes 12 for connecting to the machine tool workbench are arranged at the four corners of the mounting base plate 1.

[0017] When the utility model is in use, first, horizontally place the shaft fork to be bored on the placing through groove 41. Then, control the electric push rod 3 to contract. By using the pulling force of the electric push rod 3 during contraction on the limit pressing plate 2, and in cooperation with the sliding connection between the slider below the limit pressing plate 2 and the sliding groove 11, when the electric push rod 3 contracts, the limit pressing plate 2 and the pressing block 21 can be driven to move horizontally. Furthermore, through the movement of the pressing block 21, close contact between the fork arms at both ends of the shaft fork and the V-shaped groove 22 can be achieved. During this process, through the close contact between the V-shaped grooves 22 in the two pressing blocks 21 and the two fork arms of the shaft fork respectively, while achieving the overall positioning of the shaft fork, the overall shaft fork can also be driven to move horizontally through the pushing force of the pressing block 21 on the shaft fork, so as to complete the mating socket connection between the shaft tube end of the shaft fork and the limit groove 51. Thus, by using the placing through groove 41 to support and place the shaft fork, the V-shaped groove 22 to position and press the fork arms of the shaft fork, and the limit groove 51 to limit and support the shaft tube end of the shaft fork, the overall clamping and fixing of the shaft fork can be completed. Moreover, by setting the push plate 52 and the elastic member 53, after the boring process is completed, during the process of controlling the electric push rod 3 to expand to drive the limit pressing plate 2 and the pressing block 21 to reset, by using the elastic pushing force of the elastic member 53, the shaft fork can be pushed to move horizontally through the push plate 52, so that the shaft tube end of the shaft fork is disconnected from the limit groove 51. Adopting this structure can increase the convenience of the operation when taking out the shaft fork from the utility model after the boring process of the shaft fork is completed. Generally, the utility model has the advantages of convenient and stable operation and use.
