Description
Technical Field
The utility model belongs to the technical field of the coalignment, especially, relate to a transmission shaft coalignment.
Background
Some automotive front drive shafts use bearings mounted on the ends of the non-sliding shaft and press-fit flanges. After the flange is pressed and mounted, the jump of the end face of the flange and the inner spigot needs to be detected, the unqualified transmission shaft needs to be straightened, and the bearing seat on the transmission shaft are easily crushed by the current straightening method.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a transmission shaft coalignment that simple to use, alignment are swift.
In order to solve the technical problem, the utility model discloses a technical scheme does: the base is included, a positioning disc is arranged on the front portion of the base, a positioning groove is formed in the top of the positioning disc, the cross section of the positioning groove is in a trapezoid shape with the upper portion being large and the lower portion being small, a spring is arranged below the positioning disc, a straightening seat is arranged in the middle of the base, a straightening groove is formed in the top of the straightening seat, and the cross section of the straightening groove is arc-shaped.
The utility model provides a during the use of transmission shaft coalignment, with the pedestal mounting on the lathe workstation, place the positioning groove department at the positioning disk top with the epaxial support bearing of transmission, it is preceding that the epaxial flange of transmission is located the positioning disk this moment, the non-slip shaft of transmission shaft is located above the alignment seat. At the moment, the spring below the positioning disc plays a role, so that the positioning groove at the top of the positioning disc supports the supporting bearing, and meanwhile, a gap of about two millimeters is kept between the non-sliding shaft of the transmission shaft and the straightening seat. When the end face of the flange and the inner spigot are checked to jump, the transmission shaft rotates around the support bearing, and the non-sliding shaft is not in contact with the straightening seat. When the straightening is needed, the pressure head of the machine tool is gradually pressurized to make the transmission shaft move downwards, the spring is compressed, the non-sliding shaft is contacted with the straightening seat, the supporting force of the transmission shaft is floatingly supported by the spring force of the spring and is converted into rigid support of the non-sliding shaft and the straightening seat, and the straightening operation is started. The utility model provides a transmission shaft coalignment, when the beating of inspection transmission shaft, the transmission shaft is rotatory round the support bearing, and the detected value is exactly the actual value of beating of transmission shaft itself. In the straightening process, the non-sliding shaft is in contact with the straightening seat, so that the bearing and the bearing seat on the transmission shaft are prevented from being crushed in the straightening process, the straightening device is simple to use, and the straightening is quick.

Detailed Description
The following describes the specific structure of the transmission shaft straightening device in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the utility model provides a transmission shaft coalignment includes base 1, and base 1's front portion is provided with positioning disk 2, and 2 tops of positioning disk are equipped with positioning groove 3, and positioning groove 3's cross-section is big-end-up's trapezoidal, is equipped with spring 4 below positioning disk 2, and base 1's middle part is provided with alignment seat 5, and the top of alignment seat 5 is equipped with alignment groove 6, and alignment groove 6's cross-section is convex.
As shown in fig. 3 and 4, a positioning plate 2 is arranged at the front part of a base 1, a spring 4 is arranged below the positioning plate 2, an aligning seat 5 is arranged at the middle part of the base 1, a supporting bearing 8 on a transmission shaft 7 is arranged at a positioning groove 3 at the top of the positioning plate 2, a flange 9 on the transmission shaft 7 is positioned in front of the positioning plate 2, and a non-sliding shaft 10 of the transmission shaft 7 is positioned above the aligning seat 5.
The utility model provides a during the use of transmission shaft coalignment, install base 1 on the lathe workstation, place the positioning groove 3 department at 2 tops of positioning disk with the last support bearing 8 of transmission shaft 7, it is preceding that the last flange 9 of transmission shaft 7 is located positioning disk 2 this moment, and the non-sliding shaft 10 of transmission shaft 7 is located above the straightening seat 5. At this time, the spring 4 under the positioning plate 2 acts to ensure that the non-sliding shaft 10 of the transmission shaft 7 and the straightening seat 5 keep a clearance of about two millimeters while the positioning groove 3 at the top of the positioning plate 2 holds the support bearing 8. When the end face of the inspection flange 9 and the inner spigot jump, the transmission shaft rotates around the support bearing 7 and the support bearing 8, and the non-sliding shaft 10 is not in contact with the straightening seat 5. When the straightening is needed, the pressure head of the machine tool is gradually pressurized, the transmission shaft 7 moves downwards, the spring 4 is compressed, the non-sliding shaft 10 is in contact with the straightening seat 5, the supporting force of the transmission shaft 7 is in floating support by the spring force of the spring 4 and is converted into rigid support of the non-sliding shaft 10 and the straightening seat 5, and the straightening operation starts. The utility model provides a transmission shaft coalignment, when 7 beats of inspection transmission shaft, transmission shaft 7 is rotatory round support bearing 8, and the detected value is exactly the actual value of beating of transmission shaft 7 itself. In the straightening process, the non-sliding shaft 10 is in contact with the straightening seat 5, so that the bearing and the bearing seat on the transmission shaft 7 are prevented from being crushed in the straightening process, the straightening device is simple to use, and the straightening is quick.
The utility model provides a transmission shaft coalignment is not only limited to above-mentioned structure, and the all is in the utility model discloses any modification, equivalent replacement and improvement etc. of doing on the basis all should contain within the scope of protection of the utility model.
