In view of this, the present invention provides a device 1000 for modifying a driving shaft of an automobile. In the drawings of the present specification, fig. 1 is a schematic three-dimensional structure diagram of an automotive drive shaft modifying apparatus 1000 according to an embodiment of the present invention, fig. 2 is a schematic three-dimensional structure diagram of a slide locking device 221 of the automotive drive shaft modifying apparatus 1000 according to fig. 1, fig. 3 is a schematic three-dimensional structure diagram of a partial structure in fig. 2, fig. 4 is a schematic front view structure diagram of a partial structure in fig. 3 in a disassembled state, fig. 5 is a schematic back structure diagram of the automotive drive shaft modifying apparatus 1000 according to an embodiment of the present invention in fig. 1, fig. 6 is a schematic three-dimensional structure diagram of a testing apparatus 600 according to fig. 5, and fig. 7 is a schematic three-dimensional disassembled structure diagram of a partial structure in fig. 6.
Specifically, referring to fig. 1, the driving axle modifying apparatus 1000 for a vehicle includes a mounting base 100, a clamping assembly 200, and a connecting member 300; the clamping assembly 200 comprises a first clamping member 210 and a second clamping member 220 movably arranged on the mounting base 100 along a first direction, the first clamping member 210 and the second clamping member 220 are respectively provided with a clamping hole 213, the clamping hole 213 of the first clamping member 210 is used for clamping a limiting first driving shaft 400, the clamping hole 213 of the second clamping member 220 is used for clamping a limiting second driving shaft 500, the connecting member 300 is used for connecting the butt joint end 450 of the first driving shaft 400 and the butt joint end 450 of the second driving shaft 500, and two ends of the connecting member 300 are respectively connected with the first driving shaft 400 and the second driving shaft 500 to be spliced together. The center axes of the clamping holes 213 of the first and second clamping members 210 and 220 are arranged in a line.
In the technical solution provided by the present invention, the first direction may be along the length direction of the mounting seat 100, and the driving shaft modifying apparatus 1000 for an automobile includes the mounting seat 100, the clamping assembly 200 and the connecting member 300. The clamping assembly 200 includes a first clamping member 210 and a second clamping member 220, and two sets of driving shafts are respectively disposed on the first clamping member 210 and the second clamping member 220 through clamping holes 213. Because the central axes of the clamping holes 213 of the first clamping piece 210 and the second clamping piece 220 are arranged in a collinear manner, the coaxiality between the two groups of driving shafts can be quickly and well ensured in the assembling and remanufacturing process of the two groups of driving shafts. The problem that the coaxiality of two groups of driving shafts cannot be guaranteed in the traditional technology is effectively solved, the working efficiency of driving shaft modification is improved, the production beat is accelerated, and the production benefit is better.
Further, referring to fig. 1, the connecting rail 110 is detachably mounted on the mounting base 100, the first clamping member 210 and the second clamping member 220 are provided with sliding bases 211 matched with the connecting rail 110, and the sliding bases 211 are slidably connected to the connecting rail 110. The first clamping member 210 and the second clamping member 220 can slide on the connecting slide rail 110 through the sliding seat 211, so that the first driving shaft 400 and the second driving shaft 500 can be more conveniently butted against each other. In the docking process, the first driving shaft 400 is first mounted on the first clamping member 210, the second driving shaft 500 is mounted on the second clamping member 220, and then the sliding seat 211 is moved to dock the two members. In the technical scheme provided by the invention, the number of the first clamping pieces 210 is set to be two, and the number of the second clamping pieces 220 is also set to be two correspondingly, which is the most common arrangement mode in the actual splicing process. It should be noted that, on the basis of not departing from the essence of the present invention, the number of the first clamping member 210 and the second clamping member 220 should not be limited, and the two sets of driving shafts can be flexibly arranged according to the actual requirement, so long as the arrangement mode can stabilize the two sets of driving shafts and ensure the two sets of driving shafts to be smoothly butted with each other, and no limitation is made herein.
Further, referring to fig. 2 to 4, in order to improve the clamping effect of the first clamping member 210 and the second clamping member 220, a clamping block 212 is detachably connected to the sliding seat 211, and a clamping hole 213 is formed in the clamping block 212, specifically, the clamping block 212 includes at least two shells that are combined, and the at least two shells surround and form the clamping hole 213. If two shells are provided, one shell plays a role in supporting the driving shaft, the other shell is detachably connected to the top of the previous shell, and the two shells are matched to press the driving shaft. The two shells are correspondingly provided with semicircular grooves, the two semicircular grooves are enclosed to form a clamping hole 213, and the driving shaft is arranged in the clamping hole 213, so that the driving shaft can be stably clamped in the clamping piece, and the normal work in the splicing process is ensured.
As mentioned above, the first clamping member 210 and the second clamping member 220 can slide on the connecting rail 110 through the sliding seat 211. It should be noted that the sliding is to facilitate the butt joint of the first driving shaft 400 and the second driving shaft 500, but after passing through the connecting member 300, the two driving shafts need to be welded together by welding, so that the driving shaft modification process is completed. Therefore, during the tailor welding process, it is necessary to ensure that the sliding seat 211 is stationary relative to the connecting slide rail 110, so that the welding process is more smooth, and the welding quality is ensured. For this purpose, referring to fig. 2 to 4, the first clamping member 210 and the second clamping member 220 further include a sliding locking device 221, and the sliding locking device 221 can lock the sliding seat 211 on the connecting rail 110. Specifically, the sliding locking device 221 includes a mounting plate 222 and a locking screw 224, the mounting plate 222 is disposed on the mounting base 100, a locking groove 223 is formed in the mounting plate 222, the locking screw 224 is slidably connected to the locking groove 223 and is screwed with the clamping member after passing through the locking groove 223, so as to fix the first clamping member 210 and the second clamping member 220 at the set position of the locking groove 223. The set position is a position for facilitating the tailor welding of the first driving shaft 400 and the second driving shaft 500, and can be adjusted according to the actual condition of the size of the two groups of driving shafts which are butted.
It should be noted that, in the automobile trial development stage, the length of the driving shaft is different to adapt to different automobile models. The modified drive shaft is also set according to this length. When measuring the length of the modified drive shaft, pressure is applied to the end of the compression sleeve to make the expansion gap inside the compression sleeve zero. Thus, in the measurement process, the conventional measurement method is to perform the measurement process indirectly by using a complicated end face measurement through a size transfer method. Accordingly, referring to fig. 5 to 7, the driving shaft modifying apparatus 1000 further includes a measuring device detachably mounted on the mounting base 100, and the measuring device is used for measuring the lengths of the first driving shaft 400 and the second driving shaft 500 which are integrally joined together.
Specifically, the measuring device includes a measuring scale 610 fixedly disposed in the first direction, and a measuring pointer 620 movably disposed in the first direction, and the measuring pointer 620 and the measuring scale 610 cooperate to measure the length of the first driving shaft 400 and the second driving shaft 500 spliced together. One end of the first drive shaft 400 is a telescoping sleeve end 410 and one end of the second drive shaft 500 is a universal joint end 510. It should be noted that only one measuring pointer 620 may be provided, the measuring pointer 620 is provided at the end 410 surface of the telescopic sleeve of the first driving shaft 400, when measuring the length, the measuring pointer 620 may move on the measuring scale 610, and finally when the telescopic gap of the telescopic sleeve is zero, the reading of the end 410 surface of the telescopic sleeve may be read, and then the absolute value of the subtraction between the two may be obtained by observing the data of the end 510 surface of the universal joint. Moreover, in order to make reading of the data of the gimbal end 510 more accurate, two measuring pointers 620 may be provided, one of which is disposed on the surface of the telescopic end 410, and the other of which is disposed on the surface of the gimbal end 510, so as to further improve the measuring accuracy.
Further, the measuring pointer 620 includes a rod-shaped body having an indicating end and a connecting end which are oppositely disposed, and the connecting end is formed with a clamping groove for clamping and fixing to the first driving shaft 400 or the second driving shaft 500. It should be noted that the measuring pointer 620 needs to be able to move with the end of the telescope end 410 being compressed, remaining relatively stationary with the end face of the telescope end 410, and on the other hand needs to be indexed on the measuring scale 610, so that the measuring pointer 620 has an indexing end and a connecting end. This provides a better result for the measurement pointer 620. It should be further noted that, this is an embodiment of the measurement pointer 620, and the setting of the measurement pointer 620 may also be as follows: referring to fig. 6 and 7, the measuring pointer 620 includes an indicating pointer 621 and a connecting ring 622 having one end connected to each other, the other end of the indicating pointer 621 extends toward the measuring scale 610, and the other end of the connecting ring 622 is used to overlap the first driving shaft 400 or the second driving shaft 500. This arrangement is advantageous in that the connecting finger ring 622 can be easily replaced to accommodate drive shafts of different diameters.
As mentioned above, the measuring pointer 620 is movably disposed in the first direction. Specifically, referring to fig. 6 and 7, the measuring device includes a measuring slide rail 630 disposed side by side with the connecting slide rail 110, a measuring base 640 slidably mounted and matched with the measuring slide rail 630, a rotating boss shaft 650 disposed on the measuring base 640, a measuring pointer 620 rotatably sleeved on the rotating boss shaft 650, and a measuring scale 610 disposed on a side surface of the measuring slide rail 630. The measuring seat 640 and the rotating boss shaft 650 can make the installation of the measuring pointer 620 more stable and reliable. And, the measuring device includes a fastening nut 660, and the fastening nut 660 is used for screw-fixing the indication pointer 621 and the connection finger ring 622 to the rotation boss shaft 650. The fastening nut 660 is easily removable and the connecting finger ring 622 is easily replaced to accommodate drive shafts of different diameters.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
