DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 5 A spline detection device for a gear shaft comprises a base 1, the upper end of the base 1 is detachably connected with an internal spline detection column 3, the outer side of the internal spline detection column 3 is provided with an external spline, and the bottom of the internal spline detection column 3 is fixedly connected with a support platform 2, and the support platform 2 is connected to the base 1 by screws, so that the support platform 2 can be removed from the base 1, thereby facilitating the replacement of the internal spline detection column 3;

[0024] The side wall sliding sleeve of the inner spline detection column 3 is provided with a push plate 4, which can support the gear shaft sleeved on the inner spline detection column 3. The push plate 4 can push the gear shaft upward when it moves upward, so that the gear shaft can be removed. The upper end of the base 1 is symmetrically provided with two pushing components that drive the push plate 4 to move up and down. The pushing component includes a mounting groove 5 opened at the upper end of the base 1, and a mounting block 6 is slidably connected in the mounting groove 5. A connecting rod 7 is hinged between the mounting block 6 and the bottom of the push plate 4. The bottom of the push plate 4 and the upper end of the mounting block 6 are fixedly connected with a connecting block, and the two ends of the connecting rod 7 are rotatably connected to the two connecting blocks respectively, so that when the mounting block 6 slides in the mounting groove 5, the connecting rod 7 can rotate relative to the mounting block 6 and the push plate 4, thereby pushing the push plate 4 to move upward. A spring 10 is connected between the mounting block 6 and the inner side wall of the mounting groove 5. The spring 10 is a tension spring, which can pull the mounting block 6 to move in the direction away from the inner spline detection column 3 in a natural state. An iron block 9 is fixedly connected to the side wall of the mounting block 6. An electromagnet 8 opposite to the iron block 9 is installed on the inner side wall of the mounting groove 5. When the electromagnet 8 is energized, it can generate an attractive force with the iron block 9, so that the mounting block 6 moves toward the inner spline detection column 3. A slide bar 11 is fixedly connected to the inner side wall of the mounting groove 5. The mounting block 6 is sleeved on the slide bar 11 and slidably connected thereto. The slide bar 11 can guide the mounting block 6 so that the mounting block 6 can only move horizontally. The friction between the mounting block 6 and the slide bar 11 can buffer the mounting block 6, so that the mounting block 6 can move stably.

[0025] The upper end of the base 1 is connected to an annular plate 13 through a cylinder 12. An external spline detection plate 14 with slots at both ends is provided inside the annular plate 13. The inner side wall of the external spline detection plate 14 is provided with an internal spline. A fixing component extending into the two slots is provided in the annular plate 13. The fixing component includes two guide grooves 15 respectively provided on the front and rear inner side walls of the annular plate 13. Two cross plates 16 are slidably connected together in the two guide grooves 15. Blocks 17 are fixedly connected to the opposite inner side walls of the two cross plates 16. The two blocks 17 extend into the two grooves respectively, and can stably clamp and fix the external spline detection plate 14. A double-headed screw 18 is rotatably connected to the inner side wall of one of the guide grooves 15. The double-headed screw 18 threads penetrate the two cross plates 16. The double-headed screw 18 is driven by a servo motor 19 installed on the side wall of the annular plate 13. The servo motor 19 drives the double-headed screw 18 to rotate, and the two cross plates 16 can be moved closer to or away from each other under the threaded meshing action of the double-headed screw 18.

[0026] The functional principle of the utility model can be explained through the following operation modes:

[0027] In the utility model, when the spline detection device of the gear shaft is used, the gear shaft sleeve is arranged on the internal spline detection column 3, and the external spline on the internal spline detection column 3 can detect the internal spline on the inner wall of the gear shaft. If the gear shaft can stably slide up and down on the internal spline detection column 3, the internal spline of the gear shaft is qualified, and the push plate 4 can play a supporting role for the gear shaft;

[0028] The cylinder 12 drives the annular plate 13 to move downward, so that the external spline detection plate 14 can be moved downward and sleeved on the gear shaft. The internal splines on the external spline detection plate 14 can detect the external splines of the gear shaft. If the external spline detection plate 14 can stably slide up and down on the gear shaft, the external splines of the gear shaft are qualified.

[0029] After the detection is completed, the cylinder 12 drives the annular plate 13 to move up and reset, so that the electromagnet 8 is energized, and the electromagnet 8 and the iron block 9 generate an attractive force, which can pull the iron block 9 to slide toward the inner spline detection column 3, and the connecting rod 7 can rotate to push the push plate 4 to move upward, and push the gear shaft out of the inner spline detection column 3, so as to facilitate the removal of the gear shaft after the detection;

[0030] By removing the screws on the support platform 2, the support platform 2 can be disassembled from the base 1, and the internal spline detection column 3 can be replaced to adapt to different gear shafts. The servo motor 19 drives the double-headed screw 18 to rotate to make the two cross plates 16 move away from each other, so that the block 17 can be moved out of the slot, and the external spline detection plate 14 can be removed for easy replacement. To adapt to different gear shafts, the external spline detection plate 14 is placed between the two cross plates 16, and the two cross plates 16 are controlled to move closer to each other so that the block 17 extends into the corresponding slot, and the external spline detection plate 14 can be installed and fixed.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
