It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] The utility model provides a spline defect detection device, including a workbench 1, a detection table 2 is fixedly connected to the workbench 1, a base 201 is fixedly connected to the detection table 2, positioning blocks 202 are evenly distributed on the base 201, an external spline measuring block 203 is detachably connected to the positioning block 202, a connecting plate 204 is fixedly connected to the external spline measuring block 203, the connecting plate 204 is detachably connected to the base 201 with a bolt 205, a pressure plate 3 is slidably connected to the top of the detection table 2, mounting seats 4 are evenly distributed on the pressure plate 3, and the mounting seats 4 are movably connected to the internal spline product to be tested Product 401, the workbench 1 is fixedly connected to an oil cylinder 5, a slide rod 501 is slidably connected to the oil cylinder 5, the end of the slide rod 501 is fixedly connected to the pressure plate 3, the internal spline product 401 to be tested is movably connected to the mounting seat 4, the outer wall of the mounting seat 4 is fixedly connected to an air cylinder 402, a push rod 403 is slidably connected to the cylinder 402, the end of the push rod 403 is fixedly connected to a clamping plate 404, the clamping plate 404 abuts against the internal spline product 401 to be tested, so that the internal spline product 401 to be tested between the clamping plate 404 and the mounting seat 4 is clamped relatively stably;

[0018] When the spline defect detection device is actually used, the external spline measuring block 203 that meets the requirements is installed on the base 201 with the connecting plate 204 and the bolt 205. The external spline measuring blocks 203 are installed on the base 201 in multiple groups. Then the internal spline product 401 to be tested is installed in the mounting seat 4. The cylinder 402 on the outer wall of the mounting seat 4 drives the push rod 403 to drive the clamping plate 404 to work, so that the internal spline product 401 to be tested in the mounting seat 4 is clamped and limited. Then the oil cylinder 5 drives the slide rod 501 to drive the pressure plate 3 moves downward, and the guide column 6 at the right position of the pressure plate 3 slides in the guide sleeve 601 during the downward process, and the pressure plate 3 drives the internal spline product 401 to be tested on the mounting seat 4 to move downward until it contacts with the external spline measuring block 203. When there is a mismatch and cannot be assembled, the oil cylinder 5 is driven upward in time, and the driving cylinder 402 works to loosen the clamping plate 404 to remove the unqualified product, and the oil cylinder 5 is continued to be driven downward, and the internal spline product 401 to be tested that meets the requirements is moved downward to test whether the whole is in compliance. The inner spline product 401 to be tested on the mounting seat 4 is tested one by one in a cycle. The testing table 2 structure is set on the workbench 1, and multiple groups of positioning blocks 202 structures are evenly distributed on the testing table 2. The positioning blocks 202 are detachably installed with external spline measuring blocks 203. Then, multiple groups of mounting seats 4 are installed on the pressure plate 3. Then, the cylinder 402 drives the push rod 403 in the mounting seat 4 to drive the clamping plate 404 to mount the inner spline product 401 to be tested. The clamp is limited in the mounting seat 4, and the slide rod 501 is driven by the oil cylinder 5 to drive the pressure plate 3 downward, driving the internal spline product 401 to be tested downward to fit with the external spline measuring block 203 to complete the size detection work. Compared with the conventional method of manual detection by the staff making an external spline measuring block 203, the technical solution adopted by the utility model can realize the detection work of multiple groups of internal spline products 401 to be tested, realize semi-automatic production of size detection, liberate the labor intensity of the staff, and the overall structure is compact and easy for the staff to install and maintain.

[0019] like Figure 1-2 As shown, the mounting seat 4 and the external spline measuring block 203 are both located on the same working axis, multiple groups of the mounting seats 4 correspond one to one with multiple groups of external spline measuring blocks 203, the bottom of the pressing plate 3 is fixedly connected to a guide column 6, a guide sleeve 601 is installed on the workbench 1, the guide column 6 and the guide sleeve 601 are both slidably arranged, an oil filling port 602 is provided on the guide sleeve 601, the guide column 6 and the guide sleeve 601 are arranged on the right side of the testing table 2, and the cross section of the clamping plate 404 is arc-shaped.

[0020] The effect achieved by the entire embodiment 1 is that, during use, the mounting seat 4 and the external spline measuring block 203 are both located on the same working axis, which facilitates the testing of the internal spline product 401. The cross-section of the clamping plate 404 is designed as an arc-shaped structure, so that the internal spline product 401 to be tested can be clamped and limited in the mounting seat 4 relatively stably.

[0021] Working principle: The external spline measuring blocks that meet the requirements are installed on the base with the connecting plates and bolts. The external spline measuring blocks are installed on the base in multiple groups, and then the internal spline products to be tested are installed in the mounting seat. The cylinder on the outer wall of the mounting seat drives the push rod to drive the splint to work, so that the internal spline products to be tested in the mounting seat are clamped and limited. Then the oil cylinder drives the slide rod to drive the pressure plate downward. During the downward process of the pressure plate, the guide column at the right position slides in the guide sleeve to play a guiding role. The downward movement of the pressure plate drives the internal spline products to be tested on the mounting seat to move downward until they contact with the external spline measuring blocks. When there is a mismatch and cannot be assembled, the oil cylinder is driven upward in time, and the drive cylinder works to loosen the splint to remove the unqualified products, and continues to drive the oil cylinder downward, and the internal spline products to be tested that meet the requirements are moved downward to test whether the overall requirements are met. Once a jam occurs, reset it again to remove the unqualified products, and repeat the cycle to test the internal spline products to be tested on the mounting seat one by one.
