Description

Technical Field

[0001] The utility model relates to the technical field of differential detection, in particular to a hole position detector for the production of a differential housing. Background Technique

[0002] A differential is the main component of an automotive drive axle. Its function is to allow the two half-axles to rotate at different speeds while transmitting power to the two half-axles, so as to satisfy the unequal-distance driving of the two wheels as purely rolling as possible, and reduce the friction between the tires and the ground.

[0003] For the existing hole position detector of the differential housing, a simple detector is made according to the number and size of the holes on the differential housing. The detector consists of a detection disc and a plurality of positioning pins. When in use, the positioning pins on the detection disc are inserted into the holes of the housing to detect whether the position degrees of the holes on each part are correct. In this way, a detector for detection needs to be made for each size of differential housing detected, which is too wasteful of manpower and material resources and thus causes waste of resources.

The described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figures 1 - 3, A hole position inspection tool for differential housing production, including a bottom plate 2. A circular slide rail 3 is fixed on the upper surface of the bottom plate 2 by bolts. A clamping assembly for fixing the differential housing is provided at a position within the slide rail 3 on the upper surface of the bottom plate 2. The differential housing is clamped and fixed by the clamping assembly, so as to place the differential housing to be detected. A first carriage 4 that moves along the track of the slide rail 3 is provided within the slide rail 3. First chutes 5 are opened on both sides of the first carriage 4. A scale rod 6 is slidably connected within the first chutes 5. The scale of the scale rod 6 extends from the center point of the scale rod 6 to both sides respectively. Two second carriages 12 are slidably connected to the outside of the scale rod 6. A second threaded rod 14 is welded to the bottom of the second carriage 12. A threaded sleeve 15 is threadedly connected to the circumferential outer wall of the second threaded rod 14. A cone 16 is welded to the bottom end of the threaded sleeve 15. A first threaded rod 11 is rotatably connected to the center position at the top of the scale rod 6, and the first threaded rod 11 passes through the first carriage 4 and is threadedly connected to the first carriage 4. By rotating the first threaded rod 11, the first threaded rod 11 will move downward through the threaded engagement with the first carriage 4. The first threaded rod 11 drives the scale rod 6 to move downward along the first chute 5 to move the scale rod 6 to a suitable position. A detection assembly for measuring the hole pitch of the center hole of the differential housing is provided on the outside of the scale rod 6. Then, the second carriage 12 is moved on the scale rod 6. When the second carriage 12 moves to align the cone 16 with the hole on the differential housing, rotate the threaded sleeve 15. The threaded sleeve 15 will drive the cone 16 to move downward through the threaded engagement with the second threaded rod 14, so that the cone 16 is inserted into the hole, thereby detecting the hole position. Since the cone 16 is a conical surface, it can be applied to holes of different sizes, so that the hole positions of different differential housings can be detected, improving the use effect of the hole position inspection tool.

[0024] In the present utility model, the clamping assembly includes two second chutes 9, both of which are opened on the upper surface of the bottom plate 2. Clamping frames 10 are slidably connected within the two second chutes 9. Two fixing blocks 7 are welded to the bottom of the bottom plate 2. A first bidirectional lead screw 8 is rotatably connected between the two fixing blocks 7. The first bidirectional lead screw 8 passes through the two fixing blocks 7 and is threadedly connected to the two fixing blocks 7. A power component for driving the first bidirectional lead screw 8 to rotate is provided on one side of one of the fixing blocks 7. The power component is a motor. The motor is fixed on one side of one of the fixing blocks 7 by bolts. One end of the output shaft of the motor passes through the fixing block 7 and is fixed to the first bidirectional lead screw 8. Both of the two second chutes 9 are located within the slide rail 3. Place the differential housing between the two clamping frames 10, and then drive the first bidirectional lead screw 8 to rotate through the motor. The first bidirectional lead screw 8 will drive the two clamping frames 10 to move towards each other along the second chutes 9, so that the clamping frames 10 clamp and fix the differential housing;

[0025] Particularly, the detection component includes two third sliding brackets 19. Both of the two third sliding brackets 19 are slidably connected to the outside of the scale rod 6. Round rods 18 are welded to the bottoms of the two third sliding brackets 19. A second bidirectional lead screw 17 is provided between the two third sliding brackets 19. The two ends of the second bidirectional lead screw 17 respectively pass through the two third sliding brackets 19, and the second bidirectional lead screw 17 is threadedly connected to the two third sliding brackets 19. By rotating the second bidirectional lead screw 17, the second bidirectional lead screw 17 will cause the third sliding brackets 19 to move along the scale rod 6 through the threaded engagement with the third sliding brackets 19, so that the round rods 18 clamp from inside the central hole. At the same time, the diameter of the central hole can be detected. Pointers 13 are welded inside the two third sliding brackets 19 and the two second sliding brackets 12. A frame body 1 for supporting the bottom plate 2 is fixed to the bottom of the bottom plate 2 by bolts.

[0026] Working principle: When in use, place the differential housing between the two clamping brackets 10, and then drive the first bidirectional lead screw 8 to rotate through the motor. The first bidirectional lead screw 8 will drive the two clamping brackets 10 to move towards each other along the second sliding groove 9, so that the clamping brackets 10 clamp and fix the differential housing. Then rotate the first threaded rod 11. The first threaded rod 11 will move downward through the threaded engagement with the first sliding bracket 4. The first threaded rod 11 drives the scale rod 6 to move downward along the first sliding groove 5. Move the scale rod 6 to a suitable position, and then move the second sliding bracket 12 on the scale rod 6. When the second sliding bracket 12 moves to align the cone 16 with the hole on the differential housing, rotate the threaded sleeve 15. The threaded sleeve 15 will drive the cone 16 to move downward through the threaded engagement with the second threaded rod 14, so that the cone 16 is inserted into the hole, thereby detecting the hole position. Since the cone 16 has a conical surface, it can be applied to holes of different sizes, so that the hole positions of different differential housings can be detected, improving the use effect of the hole position detector.

[0027] In addition, the terms "installation", "setting", "connection", and "socket connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is internal communication between two devices, components, or parts. Those of ordinary skill in the art can understand the specific meanings of the above terms in this application according to specific situations.
