Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field related to half-shaft detection, and specifically relates to a special detection device for the position of a half-shaft end bolt hole. Background Art
[0002] The axle shaft, also known as the drive shaft, is the shaft that connects the differential to the drive wheel. The axle shaft transmits torque between the transmission reducer and the drive wheel. It has a universal joint (U / JOINT) on each end, connected to the reducer gear and the inner ring of the wheel hub bearing via the splines on the universal joint. The outer end of the axle shaft is provided with a flange. Typically, the flange is bolted to the wheel hub. To ensure a good assembly effect, the position of the bolt holes on the axle shaft flange must be ensured. Therefore, the position of the bolt holes on the axle shaft end must be inspected. Currently, the most commonly used method for inspecting the position of the end face holes is the three-coordinate method. This method requires the purchase of dedicated inspection equipment, which has high investment and inspection costs. Therefore, in actual processing, it is difficult to perform three-coordinate inspection on every product. Without an effective method for inspecting the position of the axle shaft end faces, the processing quality of the end face faces cannot be guaranteed.
[0003] In view of this, the present utility model is proposed. Utility Model Content
[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a dedicated detection device for the position of the bolt hole at the end of the half-shaft. In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:
[0005] A special detection device for the position of the bolt hole at the half-shaft end includes a movable support base plate and a half-shaft end detection template. A main support seat is fixedly arranged above the movable support base plate, and an installation cavity is provided in the main support seat. A lifting support seat is slidably installed in the installation cavity. The half-shaft end detection template is rotatably connected and installed on one side of the upper end of the lifting support seat through a bearing seat. A shaft end matching flange is provided on the side of the half-shaft end detection template away from the lifting support seat. A corresponding detection hole is machined on the half-shaft end detection template, and a locking screw is provided on the outer side of the main support seat. The detection device is equipped with a detection column, which is used to cooperate with the half-shaft end detection template for plug-in detection.
[0006] As a further solution of the present invention: the size specifications of the shaft end matching flange match the size specifications of the half-shaft flange, and the inner hole end position of the shaft end matching flange is processed with an inner chamfer to facilitate matching and assembly.
[0007] As a further solution of the present invention: the position, quantity and specifications of the detection corresponding holes correspond to the position, quantity and specifications of the bolt holes at the end of the half-shaft, ensuring that each end hole can be effectively detected.
[0008] As a further solution of the present invention: an observation slot is provided on the lifting support seat to prevent the hole from being blocked and affecting the observation effect, and at the same time, the weight of the detection device can be reduced.
[0009] As a further solution of the present invention: there are two locking screws, and a locking fitting hole is processed on the main support seat, and the locking fitting hole is a threaded hole. A locking pressure plate is provided at the inner end position of the locking screw, and a protective pad is provided on the pressing surface of the locking pressure plate, which can not only enhance the friction force, but also protect the pressing position of the lifting support seat.

[0013] The detection device of the utility model is equipped with a detection column. The specifications of the detection column match the specifications of the detected hole. When the hole position is observed to have a deviation, the detection column is used to perform plug-in verification to ensure the position detection effect. The detection device has a simple structure and low investment cost.

The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.
[0023] like Figures 1 to 4 As shown, a special detection device for the position of the bolt hole at the half-shaft end includes a movable support base plate 1 and a half-shaft end detection template 6. A main support seat 2 is fixedly arranged above the movable support base plate 1, and an installation cavity 12 is arranged in the main support seat 2. A lifting support seat 5 is slidably installed in the installation cavity 12. A half-shaft end detection template 6 is rotatably connected and installed on one side of the upper end of the lifting support seat through a bearing seat 16. A shaft end matching flange 9 is provided on the side of the half-shaft end detection template 6 away from the lifting support seat 5. A corresponding detection hole 7 is processed on the half-shaft end detection template 6, and a locking screw 3 is provided on the outer side of the main support seat 2. The detection device is equipped with a detection column 8, which is used to cooperate with the half-shaft end detection template 6 for plug-in detection.
[0024] The dimensions of the shaft end fitting flange 9 match those of the half shaft flange, and an inner chamfer 10 is machined at the inner hole end of the shaft end fitting flange 9 to facilitate fitting and assembly.
[0025] The position, quantity and specification of the detection corresponding hole 7 correspond to the position, quantity and specification of the bolt hole at the end of the half shaft, ensuring that each end hole can be effectively detected.
[0026] An observation slot 11 is provided on the lifting support base 5 to prevent the hole from being blocked and affecting the observation effect, and also to reduce the weight of the detection device.
[0027] There are two locking screws 3, and a locking fitting hole 13 is processed on the main support seat. The locking fitting hole 13 is a threaded hole. A locking pressure plate 14 is provided at the inner end position of the locking screw 3. A protective pad 15 is provided on the pressing surface of the locking pressure plate 14, which can not only enhance the friction force, but also protect the pressing position of the lifting support seat 5.
[0028] Moving wheels 4 are installed below the movable support base plate 1 to facilitate the movement of the device.
[0029] The working principle of the present invention is as follows: when the position of the bolt hole at the end of the half-shaft is detected, during the production process or the final inspection of the product, the half-shaft is usually placed on a material tray or a shelf, the device is moved to the flange end of the half-shaft, the locking screw 3 is loosened, the height position of the half-shaft shaft end detection template 6 is adjusted up and down, the shaft end matching flange 9 is sleeved on the outer side of the shaft end flange of the half-shaft, the shaft end matching flange 9 is processed with an inner chamfer 10 for easy matching assembly, and then the locking screw 3 is tightened, and the locking pressure plate 14 is driven to rotate by the locking screw 3. , lock and fix the position of the lifting support seat 5, and a protective pad 15 is provided on the pressing surface of the locking pressure plate 14, which can not only enhance the friction force, but also protect the pressing position of the lifting support seat 5; the half-shaft shaft end detection template 6 and the lifting support seat 5 are rotatably connected through the bearing seat 16, and the half-shaft shaft end detection template 6 is rotated to make the position of the detection corresponding hole 7 correspond to the position of the shaft end hole of the half-shaft, and observe whether there is a deviation between the detection corresponding hole 7 and the shaft end hole of the half-shaft. If there is no deviation, it means that the position of the processed end surface hole is qualified;
[0030] If a slight deviation is found between the shaft end hole of the half shaft and the observation and detection corresponding hole 7 during the observation process, the detection column 8 is inserted into the shaft end hole of the half shaft corresponding to each group and the observation and detection corresponding hole 7 to verify whether the slight deviation will affect the assembly. If it does not affect the assembly, it will be transferred to the pending product area and fed back to the technicians for judgment on whether the next process can be carried out. If it affects the assembly, it will be transferred to the unqualified product area. Note that when a slight deviation occurs, it should be fed back to the drilling process in a timely manner to clarify the cause of the hole position deviation and make timely corrections and optimizations.
[0031] Note that when the half-shaft end bolts to be tested are not tapped, the testing column 8 should use a pin that matches its size and specifications. After the half-shaft end bolt holes are tapped, the testing column 8 should use a bolt that matches its specifications to ensure the testing effect.
[0032] The present invention has a novel structure with reasonable design and is easy to install and use. The detection device is provided with a half-shaft end detection template 6 that matches the half-shaft end. The half-shaft end detection template 6 is processed with a detection corresponding hole 7 that matches the accuracy of the half-shaft processing drawing. By comparing the position of the detection corresponding hole 7 with the position of the half-shaft end processing hole, the position of the half-shaft end processing hole can be effectively and intuitively viewed. The detection device is equipped with a detection column 8. The specifications of the detection column 8 match the specifications of the detected hole. When the hole position is observed to have a deviation, the detection column is used for plug-in verification to ensure the position detection effect. The detection device has a simple structure and low investment cost. Both operators and inspectors can operate the detection and can effectively monitor the production process of the half-shaft end bolt hole.
[0033] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above-mentioned technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
