Description

Technical Field

[0001] The invention relates to the technical field of differential detection, in particular to a differential hole position detection tool. Background Art

[0002] The differential is mainly composed of left and right shaft gears, planetary gears and gear racks. The gear rack is used to set the positioning gears. The end faces of the left and right shaft gears are connected to the output shaft. In order to ensure the coaxiality of the output shaft, it is necessary to detect the positions of the shaft holes at both ends of the gear rack during manufacturing to ensure the concentricity of the shaft holes at both ends of the gear rack. In this way, when the output shaft passes through the shaft hole, the coaxiality of the left and right output shafts can be guaranteed due to the limitation of the shaft hole.

[0003] When checking the concentricity of the shaft holes of the gear rack, one of the shaft holes is usually located first, and then a gauge is used. One end of the gauge is placed on the inner wall of the other shaft hole, and then the gear rack is rotated. At this time, the gauge can be observed. The concentricity of the two shaft holes can be determined by the changes in the gauge pointer. However, the current inspection is carried out manually one by one, which not only wastes manpower but also has low efficiency.

[0004] Therefore, we propose a differential hole position inspection fixture to solve the above problems. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention can fix the gear rack and position one of the shaft holes of the gear rack by setting a turntable, a tray, an expansion sleeve and a driving mechanism, and can drive the turntable by setting a driving mechanism to drive the gear rack placed on the turntable to the bottom of the meter control component, so as to detect the gear rack using the meter control component. During the detection, when the driving mechanism drives the turntable to rotate, the rotating turntable drives the tray and the vertical rod and other structures to rotate. After the vertical rod moves to a certain position, one end of the vertical rod is resisted by the inclined guide block and moves upward, and the upward moving vertical rod drives the cone The conical block moves upward, and the upward conical block presses against the inner wall of the expansion sleeve, causing the expansion sleeve to deform, thereby causing the expansion sleeve to support the inner wall of one of the shaft hole sleeves of the gear frame to limit and fix the gear frame.

At this time, the gear frame is rotated and the concentricity of the two axial holes can be judged by observing the leaning table.

[0017] 3. The present invention sets a conical limiting hole, a conical plug and a sleeve for use. The downward moving shell will press the adjusting rod, so that the adjusting rod drives the second piston to move downward.

The moving push rod drives the conical plug to move, so that the conical plug is inserted into the conical limiting hole. The conical plug inserted into the conical limiting hole can limit the turntable, etc., and at the same time can ensure the accuracy of the structural position of the turntable, etc., so as to ensure the accuracy of the device during detection.

During the detection, when the driving mechanism drives the turntable 2 to rotate, the rotating turntable 2 drives the tray 3 and the vertical rod 8 and other structures to rotate. After the vertical rod 8 moves to a certain position, one end of the vertical rod 8 is resisted by the inclined guide block 10 and moves upward, and the upwardly moved vertical rod 8 drives the conical block 7 to move upward, and the upward conical block 7 presses against the inner wall of the expansion sleeve 4, causing the expansion sleeve 4 to deform, thereby causing the expansion sleeve 4 to support the inner wall of one of the shaft hole sleeves of the gear frame to limit and fix the gear frame. This limiting and fixing of the gear frame does not require manual operation, which not only saves manpower but is also convenient and quick. At the same time, the expansion and fixing of the gear frame by the expansion sleeve 4 is carried out by directly reducing the gap between the expansion sleeve 4 and the inner wall of the shaft hole, which can increase the stability and accuracy of the expansion sleeve 4 in positioning one of the shaft holes. The accuracy of the shaft hole positioning can improve the accuracy of detection during detection.

[0031] Furthermore, the driving mechanism includes a motor 11 fixed to the inner wall of the body 1, and the driving end of the motor 11 is fixedly connected to the rotating shaft 12, the lower surface of the turntable 2 is fixedly connected to the second gear 13, the outer wall of the rotating shaft 12 is fixedly sleeved with a first missing gear 14, and one end of the rotating shaft 12 is fixedly connected to the second missing gear 15; by setting up the motor 11, the rotating shaft 12, the first missing gear 14 and the second missing gear 15 for use in combination, the turntable 2 or one of the trays 3 can be driven to rotate.

After the gauge 23 moves down to a certain position, the connecting rod 19 is blocked by the inclined plate 22, so that the connecting rod 19 moves forward, and the forward moving connecting rod 19 drives the gauge 23 to move, so that the gauge 23 touches the other axial hole of the gear frame. At this time, the gear frame is rotated, and the concentricity of the two axial holes can be determined by observing the gauge 23. (The gauge 23 can detect the roundness of the object. After one hole is fixed as a reference, the gauge 23 can detect whether the other hole is circular when rotating with the reference hole as the center of the circle, so as to determine whether the two holes are concentric. If the detected hole is circular, it means that the two holes are concentric, otherwise it is the opposite).

[0033] Further, a conical limiting hole 24 is provided on the side wall of the turntable 2, and a conical plug 25 is provided on one side of one of the conical limiting holes 24. A sleeve 26 is fixedly connected to one side wall of the body 1, and a first piston 27 is slidably connected to the inner wall of the sleeve 26. A push rod 28 is fixedly connected to one side wall of the first piston 27, and a third spring 29 is sleeved on the outer wall of the push rod 28. One end of the push rod 28 passes through the sleeve 26 and is fixedly connected to the conical plug 25. A cavity 30 is provided inside the mounting frame 16. A connecting pipe 31 is connected to one side wall of the sleeve 26, and one end of the connecting pipe 31 is connected to the cavity 30. A second piston 32 is slidably connected to the inner wall of the cavity 30, and an adjusting rod is fixedly connected to the upper surface of the second piston 32. One end of the adjusting rod passes through It passes through the cavity 30 and extends to the bottom of the shell 17; by setting the tapered limiting hole 24, the tapered plug 25 and the sleeve 26, the downwardly moved shell 17 will press the adjusting rod, so that the adjusting rod drives the second piston 32 to move downward, and the downwardly moved second piston 32 presses the medium in the cavity 30 into the sleeve 26, so that the pressure in the sleeve 26 increases, and the increased pressure presses the first piston 27, so that the first piston 27 drives the push rod 28 to move, and the moving push rod 28 drives the tapered plug 25 to move, so that the tapered plug 25 is inserted into the tapered limiting hole 24, and the tapered plug 25 inserted into the tapered limiting hole 24 can limit the turntable 2, etc., and at the same time can also ensure the accuracy of the structural position of the turntable 2, etc., so as to ensure the accuracy of the device during detection.

[0034] Furthermore, the adjusting rod includes a threaded tube 33 fixedly connected to the second piston 32, and the inner wall of the threaded tube 33 is threadedly connected to a threaded rod 34, and the outer wall of the threaded rod 34 is threadedly sleeved with a nut 35; by setting the adjusting rod composed of the threaded tube 33, the threaded rod 34 and the nut 35, the length of the adjusting rod can be adjusted. When adjusting, the nut 35 is loosened and the threaded rod 34 can be rotated to adjust the length.

[0035] Furthermore, a limit groove is provided at the lower end of the vertical rod 8, and a ball 36 is arranged in the limit groove; by providing the ball 36, when the lower end of the vertical rod 8 contacts the inclined guide block 10, the friction between one end of the vertical rod 8 and the inclined guide block 10 can be reduced.

[0036] Furthermore, a plurality of vertical grooves 37 are formed on the upper surface of the expansion sleeve 4 , and the plurality of vertical grooves 37 are evenly distributed on the outer wall of the expansion sleeve 4 ; by providing a plurality of vertical grooves 37 , the deformation of the expansion sleeve 4 can be facilitated.

[0037] In the present invention, when in use, the gear rack to be tested is placed on the tray 3, so that one of the shaft holes of the gear rack is sleeved outside the expansion sleeve 4, and then the motor 11 is started, so that the motor 11 drives the rotating shaft 12 to rotate, and the rotating rotating shaft 12 drives the first missing gear 14 to rotate. After the first missing gear 14 rotates to a certain angle, the first missing gear 14 meshes with the second gear 13. At this time, the first missing gear 14 drives the second gear 13 to rotate, and the rotating second gear 13 drives the turntable 2 to rotate, and the rotating turntable 2 drives the gear rack to move. When the gear rack rotates to the surface Before the gear frame is moved downward, one end of the vertical rod 8 is resisted by the inclined guide block 10 and moves upward. The upward vertical rod 8 drives the tapered block 7 to move upward. The upward tapered block 7 presses against the inner wall of the expansion sleeve 4, causing the expansion sleeve 4 to deform, thereby causing the expansion sleeve 4 to support the inner wall of one of the shaft holes of the gear frame to limit and fix the gear frame. In this way, the gear frame is fixed in position without manual operation, which is convenient and quick. The expansion of the expansion sleeve 4 to fix the gear frame is carried out by directly reducing the gap between the expansion sleeve 4 and the inner wall of the shaft hole, which can increase the stability of the expansion sleeve 4 in positioning one of the shaft holes.

[0038] After the gear rack moves to the bottom of the support table 23, the first missing gear 14 rotates to a position where it is out of mesh with the second gear 13, then the motor 11 is stopped, and the cylinder 18 is started, so that the cylinder 18 pushes the housing 17 downward, and the downwardly moved housing 17 drives the connecting rod 19 and the support table 23 to move downward. After the support table 23 moves downward to a certain position, the connecting rod 19 is blocked by the inclined plate 22, so that the connecting rod 19 moves forward, and the forward moving connecting rod 19 drives the support table 23 to move, so that the support table 23 touches another shaft hole of the gear rack;

[0039] Before the table 23 touches another shaft hole, the downwardly moved housing 17 presses the adjusting rod, so that the adjusting rod drives the second piston 32 to move downward, and the downwardly moved second piston 32 presses the medium in the cavity 30 into the sleeve 26, so that the pressure in the sleeve 26 increases, and the increased pressure presses the first piston 27, so that the first piston 27 drives the push rod 28 to move, and the moving push rod 28 drives the tapered plug 25 to move, so that the tapered plug 25 is inserted into the tapered limiting hole 24, and the tapered plug 25 inserted into the tapered limiting hole 24 can be used for the turntable 2, etc. The position of the rotating disk 2 and the like can be limited, and the accuracy of the position of the rotating disk 2 and the like can be ensured. Then, the motor 11 can be started to drive the rotating shaft 12 and the second missing gear 15 to rotate. After the second missing gear 15 rotates to a certain position, the second missing gear 15 meshes with one of the first gears 6, so that the second missing gear 15 that continues to rotate drives the first gear 6 to rotate. The rotating first gear 6 drives the rotating rod 5, the tray 3 and the gear rack placed on the tray 3 to rotate. At this time, the concentricity of the two shaft holes on the gear rack can be judged by looking at the meter 23.

[0040] After the concentricity detection is completed, the second missing gear 15 rotates to a position where it is disengaged from the first gear 6, and then the motor 11 is stopped, and then the cylinder 18 is started to drive the table 23 to reset. After the table 23 is reset, the third spring 29 pushes the first piston 27, the push rod 28 and the tapered plug 25 to reset, and then the motor 11 is started again, so that the motor 11 drives the rotating shaft 12 to rotate, and the rotating rotating shaft 12 drives the first missing gear 14 to rotate. After the first missing gear 14 rotates to a certain angle, the first missing gear 14 meshes with the second gear 13. When the first gear 14 is closed, the second gear 13 is driven to rotate by the first missing gear 14, and the rotating second gear 13 drives the turntable 2 to rotate, and the rotating turntable 2 drives the gear rack and other structures to move. After the vertical rod 8 moves to a certain position, the vertical rod 8 is separated from the inclined guide block 10. After the vertical rod 8 is separated from the inclined guide block 10, the first spring 9 pushes the vertical rod 8 and the tapered block 7 to reset. After the tapered block 7 is reset, the expansion sleeve 4 loses the support of the tapered block 7, so that the expansion sleeve 4 shrinks and resets. At this time, the gear rack loses its fixation, and the gear rack can be directly removed to facilitate the removal of the gear rack after inspection.
