[0021] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.
[0022] like Figures 1 to 2 As shown, in this embodiment, a U-shaped spring AOI jig includes a jig base 1, a fixed support 2, a front-and-rear movable seat 3 and a limit movable seat 4. The fixed support 2 is fixed on the jig base 1, and the front-and-rear movable seat 3 moves on the jig base 1 along the front-and-rear direction. A first opening clamping strip 5 and a second opening clamping strip 6 are fixed on one side of the front-and-rear movable seat 3. A limiting slide groove is provided on the front-and-rear movable seat 3, and an insertion limiting plate 7 is slidably connected to the limiting slide groove. The limit movable seat 4 moves on the jig base 1 along the left and right direction. The limit movable seat 4 and the insertion limiting plate 7 are clamped with each other, and a limit opening clamping strip 8 is fixed on one side of the limit movable seat 4.
[0023] Place the U-shaped spring on the fixed support 2. When the external structure contacts the first opening clamp 5 or the second opening clamp 6, the insertion limiting plate 7 on the front and rear movable seat 3 is inserted into the U-shaped spring opening of the fixed support 2. At this time, the limit movable seat 4 extends and clamps the current position of the insertion limiting plate 7 to ensure that the insertion limiting plate 7 does not excessively stretch the U-shaped spring. When it is necessary to open the jig to remove the U-shaped spring, the external structure contacts the limit opening clamp 8 to pull open the limit movable seat 4. At this time, the insertion limiting plate 7 can be separated from the U-shaped spring along with the front and rear movable seat 3.
[0024] Front and rear slide rails 9 are fixed on the fixture base 1, and front and rear sliders 10 are fixed on the front and rear movable seat 3. The front and rear sliders 10 slide on the front and rear slide rails 9. When the front and rear movable seat 3 moves forward and backward, the movement is smoother by relying on the action of the front and rear sliders 10 and the front and rear slide rails 9.
[0025] A first spring 11 is connected between the front-rear movable seat 3 and the insertion limiting plate 7. When the limit movable seat 4 no longer clamps the insertion limiting plate 7, the insertion limiting plate 7 bounces off the front-rear movable seat 3 under the action of the first spring 11, and the position is no longer fixed.
[0026] A left-right movable seat 12 is provided on the jig base 1, and the left-right movable seat 12 moves on the jig base 1 along the left-right direction. The upper end of the left-right movable seat 12 extends into the fixed support 2. According to the position of the U-shaped spring, the front and rear directions are limited by the insertion limiting plate 7, and the left and right directions are limited by the left-right movable seat 12.
[0027] Left and right slide rails 13 are fixed on the fixture base 1, and left and right sliders are fixed on the left and right movable seat 12. The left and right sliders slide on the left and right slide rails 13. When the left and right movable seat 12 moves left and right, the movement is smoother by relying on the left and right sliders and the left and right slide rails 13.
[0028] A limiting slide rail 14 is fixed on the fixture base 1, and a limiting slider 15 is fixed on the limiting movable seat 4. The limiting slider 15 slides on the limiting slide rail 14. When the limiting movable seat 4 limits the movement of the insertion limiting plate 7, the movement is smoother by relying on the action of the limiting slider 15 and the limiting slide rail 14.
[0029] A second spring 16 is connected between the left and right movable seat 12 and one side of the jig base 1, and a third spring 17 is connected between the limit movable seat 4 and one side of the jig base 1. The second spring 16 and the third spring 17 both press the left and right movable seat 12 and the limit movable seat 4 toward the fixed support 2 in the left and right directions.
[0030] A left and right opening strip 18 is fixed to one side of the left and right movable seat 12. The upper end of the first opening strip 5, the lower end of the second opening strip 6, the lower end of the limit opening strip 8 and the lower ends of the left and right opening strips 18 are all provided with inclined surfaces 19. When a guide wheel is installed externally, the guide wheel rolls on the inclined surface 19, so that the opening strips are unfolded according to the direction of movement.
[0031] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present invention and the technical principles used. Within the technical scope disclosed by the present invention, any changes or replacements that can be easily thought of by technicians familiar with this technical field should be included in the scope of protection of the present invention.
