[0028] Example

[0029] like Figure 1-8 As shown, the utility model proposes a tooling fixture for positioning a sensor housing, comprising a base 1 and a clamping mechanism for fixing the sensor housing, and also comprising: an adjusting mechanism for adjusting the sensor housing on the clamping mechanism at multiple angles; and a rotating mechanism arranged in the base 1 for clamping the clamping mechanism after the angle adjustment is completed.

[0030] Further, the adjustment mechanism includes a hemispherical card seat 2 fixedly connected to the base 1, a hemispherical groove 21 is provided on the top of the hemispherical card seat 2, a spherical rotating block 4 is rotatably connected inside the hemispherical groove 21, and a plurality of pulling springs 22 for pulling the spherical rotating block 4 to return to its original position in the hemispherical groove 21 are fixedly connected inside the hemispherical groove 21, and the function of the pulling spring 22 is to make the spherical rotating block 4 automatically return to its original position after being free of control force. Figure 1 state.

[0031] The adjustment mechanism further includes a plurality of clamping holes 41 provided at the bottom of the spherical rotating block 4. The function of the clamping holes 41 is to limit the position of the spherical rotating block 4 after being clamped by the telescopic protrusion 23. Each clamping hole 41 is clamped by the telescopic protrusion 23 to adjust the spherical rotating block 4 to a different position. The base 1 is provided with a rotating groove 11. The inner bottom wall of the hemispherical holder 2 is movably connected to the telescopic protrusion 23 with one end for inserting into the clamping hole 41. The other end of the telescopic protrusion 23 in the rotating groove 11 is fixedly connected with a clamping button 25. The telescopic protrusion 23 is sleeved with a push spring 24 for driving the telescopic protrusion 23 to automatically disengage from the clamping hole 41. The function of the push spring 24 is to push the clamping button 25 to drive the telescopic protrusion 23 to disengage from the clamping hole 41 under normal conditions.

[0032] Secondly, the rotating mechanism includes a fixed pinching rod 15 fixedly connected to the base 1 and corresponding to the rotating groove 11. The fixed pinching rod 15 and the rotating pinching rod 16 are provided with a plurality of linearly arranged anti-skid grooves 19. The anti-skid grooves 19 are generally used to increase the friction force of the surface of an object to prevent it from sliding or shifting under certain conditions. The rotating groove 11 is internally rotatably connected with a rotating stopper 12. The rotating stopper 12 is provided with an inclined stopper 13 for stopping the bottom clamping button 25 of the telescopic protrusion 23 from moving toward the clamping hole 41. The function of the inclined stopper 13 is to make the clamping button 25 being stopped slowly move toward the clamping hole 41. The interior of the rotating groove 11 is fixedly connected with a rotating rod 14 for supporting the rotation of one end of the rotating stop block 12, and the end of the rotating stop block 12 close to the rotating rod 14 is fixedly connected with a rotating pinching rod 16. The inner wall of the rotating groove 11 is fixedly connected with a return spring 17 for pulling the rotating pinching rod 16 to return to its original position. The function of the return spring 17 is to make the rotating pinching rod 16 return to its original position by the thrust of the return spring 17 after the rotating clamp 18 does not clamp the fixed pinching rod 15. Figure 7 In the state shown, the inclined stopper 13 on the rotating stopper 12 does not stop the button 25. The end of the rotating pinching rod 16 that escapes from the rotating groove 11 is rotatably connected to a rotating clamping ring 18 for hanging and fixing the pinching rod 15. The function of the rotating clamping ring 18 is to clamp the telescopic protruding rod 23 to prevent the telescopic protruding rod 23 from escaping from the inserted clamping hole 41.

[0033] Furthermore, the clamping mechanism includes a clamping sleeve 3 fixedly connected to the top of the spherical rotating block 4, and the outer wall of the clamping sleeve 3 is fixedly connected with an adjusting handle 5 for enabling the clamping sleeve 3 to adjust the position of the spherical rotating block 4 in the hemispherical groove 21, and the function of the adjusting handle 5 is to save time and effort in adjusting the position of the spherical rotating block 4 in the hemispherical groove 21. The outer wall of the clamping sleeve 3 is fixedly connected with a spiral support 31, and a spiral rod 32 with one end passing through the clamping sleeve 3 is spirally connected to the spiral support 31, and a rotating handle 33 is fixedly connected to the other end of the spiral rod 32, and a clamping plate 34 is rotatably connected to one end of the spiral rod 32 in the clamping sleeve 3, and the material of the clamping plate 34 is rubber, and its function is to protect the clamped sensor housing and prevent the clamped outer wall of the sensor housing from being damaged.

[0034] In this embodiment, when it is necessary to use a fixture for positioning the sensor housing, such as Figure 1 As shown, the sensor housing is placed inside the clamping sleeve 3, and then the rotating handle 33 is rotated to drive the spiral rod 32 to rotate. Since the spiral rod 32 and the spiral support 31 are spirally connected, one end of the spiral rod 32 in the clamping sleeve 3 pushes the clamping plate 34 to press against the sensor housing in the clamping sleeve 3, thereby completing the clamping and fixing of the sensor housing.

[0035] When it is necessary to align some parts of the sensor housing with other components or equipment for welding, it is only necessary to rotate the adjustment handle 5 to drive the clamping sleeve 3 and the sensor housing fixedly clamped in the clamping sleeve 3 to rotate and adjust, and the spherical rotating block 4 at the bottom of the clamping sleeve 3 is rotated and adjusted in the hemispherical groove 21 at the top of the hemispherical holder 2, so that the sensor housing is adjusted to the specified position. Then pinch the rotating pinching rod 16 in the direction of the fixed pinching rod 15, and the rotating pinching rod 16 drives one end of the rotating block 12 to rotate inside the rotating groove 11 through the rotating rod 14. After the inclined block 13 on the rotating block 12 presses against the clamping button 25, the clamping button 25 drives the telescopic protrusion 23 to move in the direction of the clamping hole 41 until the top of the telescopic protrusion 23 is inserted into the clamping hole 41 at the bottom of the spherical rotating block 4 directly above. Finally, the rotating clamping ring 18 on one end of the rotating pinching rod 16 can be rotated to cover one end of the fixed pinching rod 15. At this time, the rotating abutment block 12 abuts against the bottom end of the button 25, so that the button 25 cannot move downward by the elastic thrust of the push spring 24, so that the top end of the telescopic protrusion 23 can be inserted into the clamping hole 41 at the bottom of the spherical rotating block 4, so that the sensor housing in the clamping sleeve block 3 is fixed at a specified position, which is simple and easy to operate.
