Description

Technical Field

[0001] This utility model relates to the field of flange hole measurement technology, specifically a differential housing flange hole position measurement device. Background Technology

[0002] In automotive transmission systems, the differential housing is the core component enabling differential rotation of the left and right wheels. Its flange bore, as a crucial interface connecting to the drive shaft and reducer, directly impacts the assembly quality and operational stability of the transmission system. For example, a flange bore positional deviation exceeding 0.1mm can cause misalignment between the drive shaft and the differential, leading to abnormal transmission noise, increased vibration, and, with prolonged use, excessive bearing wear, shortening the vehicle's lifespan. In new energy vehicles, precise positioning of the differential flange bore is a critical prerequisite for ensuring efficient power transmission and reducing energy consumption.

[0003] Traditional methods for measuring the position of flange holes in differential housings have many limitations and cannot meet the requirements of high-precision production. Manual measurement relies on tools such as dial indicators and plug gauges, and calculates the deviation value through multi-point sampling. This is not only cumbersome to operate, but also affected by the skill level of the operator. The measurement error can reach more than 0.05mm. For differential housings with densely distributed flange holes, manual measurement is difficult to ensure the positional accuracy of each hole, and is prone to missed detections or misjudgments.

[0004] To address the aforementioned issues, we propose a differential housing flange hole position measurement device. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Example 1: Please refer to Figure 1 - Figure 3 This embodiment of a differential housing flange hole position measuring device includes an operating table 1 and a detection plate 2. A hydraulic cylinder 6 is fixedly connected to one end of the top of the operating table 1. A lifting plate 7 is fixedly connected to the top of the hydraulic cylinder 6. A horizontal plate 8 is fixedly connected to the top of the lifting plate 7. A fixed seat 9 is fixedly connected to one end of the horizontal plate 8. A connecting seat 10 is provided at the bottom of the fixed seat 9. The detection plate 2 is fixedly connected to the bottom of the connecting seat 10. A positioning column 3 is fixedly connected to the bottom of the detection plate 2. Multiple detection columns 4 are fixedly connected to the bottom of the detection plate 2. A prism groove 12 is machined inside the fixed seat 9. A prism block 11 is fixedly connected to the top of the connecting seat 10. The prism block 11 is plugged into the inside of the prism groove 12. A handle 13 is provided on one side of the fixed seat 9. A limit pin 14 is fixedly connected to the inside of the handle 13. One end of the limit pin 14 is plugged into the inside of the prism block 11.

[0022] When it is necessary to measure and inspect the flange holes of the differential housing, the differential housing is first placed on the top of the operating table 1. The inspection plate 2 is the corresponding standard hole position inspection plate. The housing is clamped and fixed by two clamping plates 5. At the same time, the longest positioning pin 3 is aligned with one of the holes of the housing flange. Then, the hydraulic cylinder 6 is started. The hydraulic cylinder 6 will drive the lifting plate 7 to move downward. The lifting plate 7 will drive the horizontal plate 8 to move downward. The horizontal plate 8 will drive the fixed seat 9 to move downward. The fixed seat 9 will drive the connecting seat 10 to move downward. The connecting seat 10 will drive the inspection plate 2 to move downward. The inspection plate 2 will drive the positioning pin 3 and the inspection pin 4 to move downward. Observe whether the positioning pin 3 and the inspection pin 4 are inserted into all the flange holes, so as to determine whether the position of the housing flange hole is qualified.

[0023] When it is necessary to measure the flange holes of different models of housings, pull the handle 13. The handle 13 will drive the limit pin 14 to move outward, thereby disengaging the limit pin 14 from the interior of the prism block 11, and thus disengaging the prism block 11 from the interior of the prism groove 12, so as to facilitate the quick removal of the test disc 2 and the replacement of the new standard disc.

[0024] Furthermore, a limiting hole 15 is machined on one side of the prism block 11, and a limiting pin 14 is plugged into the inside of the limiting hole 15. The limiting pin 14 is movably connected to the inside of the fixed base 9. When the handle 13 is pulled outward, the handle 13 will drive the limiting pin 14 to move, and the limiting pin 14 will disengage from the inside of the limiting hole 15, thereby releasing the limiting of the prism block 11.

[0025] Furthermore, the fixed base 9 has a groove 16 machined inside, and a connecting plate 17 is fixedly connected to one side of the limiting pin 14. The connecting plate 17 is movably connected inside the groove 16. When the handle 13 drives the limiting pin 14 to move outward, the limiting pin 14 will drive the connecting plate 17 to move. The connecting plate 17 will move along the inside of the groove 16, and at the same time, the connecting plate 17 will compress the return spring 18.

[0026] Furthermore, a return spring 18 is provided inside the groove 16. One end of the return spring 18 is fixedly connected to the inner wall of one end of the groove 16, and the other end of the return spring 18 is fixedly connected to one side of the connecting plate 17. With the return spring 18 provided, when the handle 13 is pulled, the connecting plate 17 will drive the return spring 18 to compress. When the handle 13 is released, the return spring 18 will return to its original position and extend. The return spring 18 will drive the connecting plate 17 to move, thereby allowing the limit pin 14 to be inserted into the interior of the limit hole 15.

[0027] Furthermore, a motor 19 is provided on one side of the operating platform 1. One end of the motor 19 is fixedly connected to a bidirectional threaded rod 20. The two ends of the bidirectional threaded rod 20 are threadedly connected to two threaded seats 21. The top of the threaded seats 21 is fixedly connected to a clamping plate 5. The clamping plate 5 is movably connected to the top of the operating platform 1. When it is necessary to clamp and fix the differential housing, the motor 19 is started. The motor 19 will drive the bidirectional threaded rod 20 to rotate. The bidirectional threaded rod 20 will drive the threaded seats 21 to move. The threaded seats 21 will drive the two clamping plates 5 to move closer to each other to clamp and fix the housing.

[0028] Furthermore, the top of the operating table 1 is machined with a movable groove 22, and the threaded seat 21 is movably connected inside the movable groove 22. By setting the movable groove 22, the movable groove 22 will limit the movement of the threaded seat 21, so that the clamping plate 5 remains stable when it moves.

[0029] Furthermore, the top of the operating platform 1 is fixedly connected to two guide rods 23, and the bottom ends of the lifting plate 7 are fixedly connected to two limiting plates 24. The top of the guide rods 23 is movably connected to the inside of the limiting plates 24. When the hydraulic cylinder 6 drives the lifting plate 7 to move upward, the lifting plate 7 will drive the limiting plates 24 to move. The limiting plates 24 will move along the outside of the guide rods 23, thereby limiting the movement of the lifting plate 7.

[0030] Working principle: The housing is clamped and fixed by two clamping plates 5, and the positioning pin 3 is aligned with one of the holes of the housing flange. Then, the hydraulic cylinder 6 is activated. The hydraulic cylinder 6 will drive the lifting plate 7, the horizontal plate 8, the fixed seat 9 and the connecting seat 10 to move downward. The connecting seat 10 will drive the detection plate 2 to move downward. The detection plate 2 will drive the positioning pin 3 and the detection pin 4 to move downward. Observe whether the positioning pin 3 and the detection pin 4 are inserted into all the flange holes, so as to determine whether the position of the housing flange hole is qualified.
