Description

Technical Field

[0001] The present invention relates to the technical field of drive shaft component assembly, and more particularly to an assembly tooling for a high-speed drive shaft hollow tube and a fixed joint. Background Art

[0002] A drive shaft is an important component for transmitting power in an automotive transmission system. Its function is to transmit the torque and rotational speed output by a transmission (or transfer case) to the main reducer of a drive axle, thereby driving the vehicle to move. Among them, a fixed joint (universal coupling) specifically refers to a component in a two-piece drive shaft. The two-piece drive shaft consists of two front and rear drive arms (hollow tubes) and an intermediate universal joint shaft (movable joint). The fixed joint b is the relatively fixed part of the two-piece drive shaft. It is usually installed at one end of the drive arm and connected to the transmission or the main reducer of the drive axle through connection methods such as flanges or splines. The other end of the drive arm is connected to another drive arm through a universal joint shaft to form a relatively rotatable connection. In production, there is an assembly process for the hollow tube and the fixed joint, that is, the process of pressing the pin shaft on the end face of the hollow tube into the pin sleeve of the fixed joint.

[0003] Traditionally, there are many challenges in the assembly process of the drive shaft hollow tube and the fixed joint: on the one hand, the assembly efficiency between the hollow tube and the fixed joint is low, and the labor cost is high; on the other hand, accuracy loss is likely to occur during the assembly process, that is, there is a positional deviation between the pin shaft and the pin sleeve, which is likely to cause damage to the parts. Therefore, developing an efficient and precise assembly tooling is of great significance for improving the manufacturing quality and production efficiency of drive shafts. Summary of the Invention

The middle column passes through the intersection of the strip-shaped through grooves of the arm plate one and the arm plate two.

[0008] Furthermore, the press-fitting mechanism also includes a fixed side plate and several moving arms. Several rotating shafts are rotationally sleeved on one side of the fixed side plate, and several motor ones are installed on the other side of the fixed side plate. The output ends of the several motor ones are respectively connected with the several rotating shafts. One ends of the several rotating shafts are all fixedly connected with a first threaded rod.

[0018] The following will describe in detail the detailed implementation manners of the present invention with reference to the accompanying drawings

[0019] Referring to Figures 1-4 , the present invention provides a high-speed drive shaft hollow tube and fixed section assembly tooling, including a bottom platform 1 and a press-fitting mechanism 3. A plurality of support plate assemblies 2 are symmetrically arranged at the top of the bottom platform 1 in the horizontal center. Two symmetric support plate assemblies 2 are used to place the hollow tube a for discharging the assembled hollow tube a and fixed section b The press-fitting mechanism 3 has a plurality of press-fitting seats 35 and is respectively aligned with a plurality of symmetric support plate assemblies 2. The press-fitting seats 35 are used to place the fixed section b and apply a pressure towards the support plate assemblies 2 V-shaped placement notches are provided at the tops of the support plate assemblies 2 and the press-fitting seats 35 A conveying mechanism 4 is provided at the gap between a plurality of symmetric support plate assemblies 2

[0020] During use, the hollow tube a is placed on the symmetrically arranged support plate assembly 2, and the fixed section b is placed on the press-fitting seat 35. Since V-shaped placement notches are provided at the tops of both the support plate assembly 2 and the press-fitting seat 35, they can center the hollow tube a and the fixed section b, thereby ensuring the assembly accuracy. Since several support plate assemblies 2 and press-fitting seats 35 are symmetrically arranged, multi-station assembly can be realized to improve work efficiency. After the assembly is completed, the support plate assembly 2 can be used to unload the hollow tube a and the fixed section b from the V-shaped placement notches of the support plate assembly 2 and the press-fitting seat 35. After unloading, the hollow tube a falls onto the top of the conveying mechanism 4, and the assembled hollow tube a and fixed section b are output from the top of the base table 1 through the conveying mechanism 4, enabling the tooling to automatically unload after the assembly work is completed, further improving the efficiency.

[0021] Referring to Figure 5 , the support plate assembly 2 includes a main support plate 21 and a lifting mechanism 25. The top of the main support plate 21 is set as an inclined surface. There is an intermediate layer inside the main support plate 21, and a top plate assembly 22 is arranged in the intermediate layer. The top of the top plate assembly 22 is set as an inclined surface. The bottom of the top plate assembly 22 is fixedly connected with a jacking frame 23. Two positioning connection blocks 24 are arranged on the front and back of the jacking frame 23. Two positioning sliding grooves are formed on the front and back of the main support plate 21. The two positioning connection blocks 24 are docked with the lifting mechanism 25, and the lifting mechanism 25 is used to control the lifting of the jacking frame 23.

[0022] In the initial state, the top plate assembly 22 is located at the bottom of the V-shaped placement notch of the support plate assembly 2. When unloading through the support plate assembly 2, the lifting mechanism 25 operates to drive the jacking frame 23 to jack up, and the jacking frame 23 drives the top plate assembly 22 to rise into the V-shaped placement notch to support the hollow tube a. When the top of the top plate assembly 22 is flush with the top of the main support plate 21, under the influence of the inclined surfaces at the tops of the main support plate 21 and the top plate assembly 22, the hollow tube a rolls and detaches from the top of the support plate assembly 2. Since the hollow tube a is connected to the fixed section b, through the above actions, the fixed section b is driven by the hollow tube a and detaches from the V-shaped placement notch at the top of the press-fitting seat 35.

[0023] Referring to Figures 5-7The top material plate assembly 22 includes two top material side plates 221, and the inner sides of the two top material side plates 221 are fixedly connected with a middle column 222; the top material plate assembly 22 also includes an arm plate 1 223 and an arm plate 224. The front sides of the arm plate 1 223 and the arm plate 224 are both provided with strip-shaped grooves, and the arm plate 224 is provided with an intermediate interlayer. The bottom end of the arm plate 1 223 passes through the intermediate interlayer of the arm plate 224, and the top ends of the arm plates 1 223 and the arm plates 224 are rotatably sleeved in the intermediate layer of the main support plate 21 through knobs, and the top ends of the arm plates 1 223 and the arm plates 224 are located symmetrically on both sides of the V-shaped placement notch of the support plate assembly 2, and the middle column 222 passes through the intersection of the strip-shaped grooves of the arm plates 1 223 and the arm plates 224.

[0024] The V-shaped placement notch shape characteristic of the support plate assembly 2 can play a centering effect on the hollow tube a. However, in production, there are inevitably slight size differences in the hollow tube a. When there is an error in the diameter of the hollow tube a, the V-shaped placement notch on the top of the support plate assembly 2 can only ensure that the hollow tube a is horizontally aligned with the fixed section b, while there is a slight vertical misalignment, which affects the assembly accuracy. Therefore, arm plate 1 223 and arm plate 2 224 are arranged to form a V-shaped arm according to their connection positions, and when the top plate assembly 22 is lifted, a toggle effect can be formed on arm plate 1 223 and arm plate 2 224 (such as Figure 7 As shown: the opening and closing degree of the V-shaped arm formed by the arm plate 1 223 and the arm plate 2 224 is adjusted, that is, the opening and closing degree of the V-shaped placement groove of the support plate assembly 2 is adjusted, so that the vertical accuracy of the hollow tube a can be adjusted to further improve the assembly accuracy).

[0025] Reference Figure 3 The pressing mechanism 3 also includes a fixed side plate 32 and a plurality of movable arms 31. A plurality of rotating shafts 33 are rotatably sleeved on one side of the fixed side plate 32. A plurality of motors 34 are installed on the other side of the fixed side plate 32. The output ends of the plurality of motors 34 are respectively connected to the plurality of rotating shafts 33. One end of the plurality of rotating shafts 33 is fixedly connected to a threaded rod 36. The plurality of movable arms 31 are respectively threadedly sleeved on the side walls of the plurality of threaded rods 36. The plurality of pressing seats 35 are respectively fixedly connected to the tops of the plurality of movable arms 31. The fixed side plate 32 is fixedly connected to the side wall of the base 1. The top height of the fixed side plate 32 is higher than the top height of the support plate assembly 2.

[0026] When the pressing mechanism 3 is running, the motor 34 provides power to drive the rotating shaft 33 to rotate, and the rotating shaft 33 drives the threaded rod 36 to rotate. Under the action of the threaded structure, the movable arm 31 is displaced, and then the pressing seat 35 is moved to apply pressure to the fixed section b. In addition, the height setting of the fixed side plate 32 can play a supporting role on the other end of the hollow tube a, thereby avoiding axial displacement of the hollow tube a during the pressing process.

[0027] Reference Figure 3A plurality of T-shaped slide grooves are provided at the bottom of the base 1, the movable arms 31 are arranged in a T-shape, and the plurality of movable arms 31 are slidably sleeved in the plurality of T-shaped slide grooves respectively.

[0028] This arrangement enables the base 1 to bear the weight of the movable arm 31, thereby preventing the threaded rod 36 from being subjected to a large vertical pressure. At the same time, the movable arm 31 is positioned to prevent the movable arm 31 from rotating with the threaded rod 36 and affecting the displacement effect.

[0029] Reference Figure 3 Two position sensors 5 are arranged on the top of each of the moving arms 31, and the two position sensors 5 are used to detect the alignment state of the hollow tube a and the fixed section b.

[0030] A position sensor 5 is used to detect the distance to the side wall of the pin shaft a1 of the hollow tube a, and another position sensor 5 is used to detect the distance to the side wall of the pin sleeve b1 of the fixed section b. The distance difference detected by the two position sensors 5 and the wall thickness of the pin sleeve b1 are fixed values. When the distance difference detected by the two position sensors 5 does not meet the fixed value, it can be determined that the core tube a and the fixed section b are not aligned, thereby achieving the alignment status detection effect. This method replaces the manual observation and judgment method, and the assembly accuracy can be further improved.

[0031] Reference Figure 4 A V-shaped support frame 351 is fixedly connected in the V-shaped placement grooves of the plurality of press-fit seats 35 .

[0032] Since the fixed joint b is a universal coupling structure, its pin sleeve b1 can be movable, and the V-shaped bracket 351 can be provided to center the pin sleeve b1, ensuring that the pin sleeve b1 can be aligned with the pin shaft a1 of the hollow tube a 4.

[0033] Reference Figure 7 When the arm plate 1 223 and the arm plate 2 224 are in a horizontal state, their top heights are lower than the top heights of the top material side plate 221 .

[0034] To avoid that after the hollow tube a is pushed out of the V-shaped placement groove of the support plate assembly 2 by the ejector plate assembly 22, the arm plate 1 223 and the arm plate 2 224 protrude from the top inclined surface of the ejector plate assembly 22, thereby affecting the rolling of the hollow tube a.

[0035] Reference Figure 8 The lifting mechanism 25 includes two threaded rods 251, a transmission rod 1 252, and a motor 253. Both ends of the two threaded rods 251 are rotatably sleeved with end blocks, and the end blocks are fixedly connected to the outer wall of the main support plate 21. The bottom ends of the two threaded rods 251 are respectively connected to the transmission rod 1 252 through two bevel gear transmission groups 255. The output end of the motor 253 is connected to the transmission rod 1 252 through the bevel gear transmission group 1 254. The two positioning connection blocks 24 are respectively threadedly sleeved on the side walls of the two threaded rods 251.

[0036] The power output by the motor 253 rotates the transmission rod 1 252 under the transmission action of the bevel gear transmission group 1 254, and then the two threaded rods 251 rotate through the transmission action of the two bevel gear transmission groups 255, and the positioning connection block 24 is raised and lowered through the threaded structure, thereby driving the lifting frame 23 to lift.

[0037] Reference Figure 9 The conveying mechanism 4 includes a plurality of conveyor belts 41 and a motor 3 43. The driving wheels and the driven wheels of the plurality of conveyor belts 41 are connected through a transmission rod 2 42. The output end of the motor 3 43 is connected to one end of the transmission rod 2 42. A plurality of box slots are provided on the top of the base 1, and the plurality of conveyor belts 41 are respectively arranged in the plurality of box slots.

[0038] After the several symmetrically arranged support plate assemblies 2 are unloaded, the hollow tube a is placed on the top of the several conveyor belts 41, and the output of the motor 3 43 drives the transmission rod 2 42 to rotate, so that the several conveyor belts 41 run simultaneously to transport the hollow tube a.

The above embodiments and descriptions are only for explaining the principles of the present invention.
