Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts, specifically to a hole position detection device for a bearing housing of an automotive drive shaft. Background Technology
[0002] In the traditional aftermarket, the development and verification cycle of bearing housing products is generally long. The main technical bottleneck is that when determining the position of each mounting hole based on the bearing center, the actual machining dimensions of these holes cannot be directly and accurately measured by conventional means due to structural obstruction and limitations of measuring tools.
[0003] Existing techniques typically require 3D scanning of physical samples, reconstructing a 3D digital model through reverse engineering, and then extracting and measuring the hole coordinates within that model. After model measurement, a secondary check and verification of the hole positions is necessary using specialized gauges. This further increases the development cycle and verification costs. Utility Model Content
[0004] To overcome the shortcomings of the prior art, this utility model provides a hole position detection device for bearing housings of automotive drive shafts, mainly solving the problem that there is currently no hole position detection device for drive shaft bearing housings.
[0005] The technical solution of this utility model is as follows: A hole position detection device for a bearing housing of an automotive driveshaft includes a base plate and a back plate, wherein the back plate is arranged perpendicularly to the base plate; it also includes... A cylindrical bracket, detachably connected to the back plate, is used to be inserted into the large hole of the bearing seat; A skateboard is mounted on the back plate and moves back and forth along the X-axis. A long groove is provided on the slide plate and extends along the Z-axis. A scale layer is provided on the slide plate and is positioned opposite to the long groove; A locating pin, movably mounted in the long slot, which extends along the Y-axis, is used to insert into a small hole in the bearing housing.
[0006] The base plate is mounted on the back plate with adjustable height along the Y-axis direction.
[0007] The back plate is provided with a groove along the Y-axis, and the bottom plate is provided with a slider that cooperates with the groove.
[0008] The slider is provided with a threaded locking member, which is in abutting engagement with the back of the back plate.
[0009] The top end face of the back plate is provided with a second sliding groove, and the bottom of the slide plate is provided with a second slider that cooperates with the second sliding groove.
[0010] The back plate is provided with mounting holes, and the cylindrical bracket is provided with pins that engage with the mounting holes.
[0011] The positioning pin includes a top cover and a pin body. The top cover is located on the upper end face of the slide plate, and the pin body passes through the long groove and its tail end extends into the small hole of the bearing seat.
[0012] The back plate is provided with a second scale layer, which is disposed opposite to the slide groove.
[0013] The beneficial effects of this utility model are: This utility model provides a hole position detection device for bearing housings of automobile drive shafts, which realizes rapid and accurate verification of the hole position of bearing housings based on the unified design principle of bearing housing products with the bearing center as the reference.

[0018] The present invention will be further described below with reference to the accompanying drawings. A hole position detection device for a bearing seat of an automobile drive shaft includes a base plate 1 and a back plate 2, wherein the back plate is arranged perpendicularly to the base plate; it also includes a cylindrical bracket 3, which is detachably connected to the back plate and is used to insert into the large hole of the bearing seat; and a sliding plate 4, which is mounted on the back plate and moves back and forth along the X-axis. A long groove 41 is provided on the slide plate and extends along the Z-axis. A scale layer 42 is provided on the slide plate and is positioned opposite the long groove. A positioning pin 5 is movably installed in the long groove and extends along the Y-axis; it is used to extend into the small hole of the bearing housing. In use, the large hole of the bearing housing is fitted over the cylindrical bracket, with the bottom end face of the bearing housing in contact with the base plate and its rear end face in contact with the back plate. The slide plate and the positioning pin are slid to allow the positioning pin to extend into the small hole. At this time, the reading of the scale layer can be read to obtain the relevant dimensions, which is convenient for use. The cylindrical bracket can be replaced according to the specifications of the bearing in the bearing housing to be measured.
[0019] In this embodiment, as shown in the figure, the base plate is mounted on the back plate with adjustable height along the Y-axis. The height of the base plate is adjusted to accommodate bearing seats with different large bore diameters.
[0020] In this embodiment, as shown in the figure, the back plate is provided with a groove 21 along the Y-axis direction, and the bottom plate is provided with a slider 11 that cooperates with the groove.
[0021] In this embodiment, as shown in the figure, the slider is provided with a threaded locking member 12, which abuts against the back of the back plate. A wing bolt can be used for fixing.
[0022] In this embodiment, as shown in the figure, the top end face of the back plate is provided with a second sliding groove 24, and the bottom of the slide plate is provided with a second slider that cooperates with the second sliding groove. The second sliding groove can be a convex shape or a dovetail groove, etc.
[0023] In this embodiment, as shown in the figure, the back plate is provided with mounting holes 22, and the cylindrical bracket is provided with pins 31 that engage with the mounting holes. Assembly and disassembly are relatively convenient.
[0024] In this embodiment, as shown in the figure, the positioning pin includes a top cover 51 and a pin body 52. The top cover is disposed on the upper end face of the slide plate, and the pin body passes through the elongated groove with its tail end extending into the small hole of the bearing seat. An arrow can be provided on the top cover for easy data reading.
[0025] In this embodiment, as shown in the figure, a second scale layer 25 is provided on the back plate, and the second scale layer is disposed opposite to the slide groove. The surface of the back plate is provided with numerical scales based on the bearing center, which can be accurately read according to the actual moving position of the base plate, thereby directly obtaining the dimension between the center surface of the large hole and the bottom end face of the bearing seat.
