[0027] The measuring assembly includes a measuring support plate 18, guide posts 19 are arranged on both sides of the upper surface of the measuring support plate 18, and two upper and lower T-blocks 20 are arranged on the upper outer surface of the measuring support plate 18 between the two guide posts 19. The two T-blocks 20 are connected by spring sheets 21 on the left and right sides, and a pressure block 22 is arranged on the outer surface of the spring sheet 21. Pull nails 23 are arranged on the outer surfaces of the left and right sides of the upper T-block 20. A first reference 24 is arranged on the upper outer surface of the upper T-block 20, a center guide sleeve 26 is arranged on the upper end of the first reference 24, and a second reference 25 is arranged on the lower outer surface of the center guide sleeve 26;

[0028] The up and down driving assembly includes a support 6, a fixed plate 7 is fixedly installed on the upper outer surface of the support 6, a servo motor 8 is fixedly installed on the rear outer surface of the fixed plate 7, a slide rail 10 is fixedly installed on the front side of the fixed plate 7, and a sliding plate 11 is slidably arranged on the outer surface of the slide rail 10;

[0029] The pressing assembly includes a cylinder body 12, a pressing rod 13 is inserted inside the cylinder body 12, a pressing spring 14 is sleeved on the outer surface of the pressing rod 13, a pressing head 15 is fixedly installed on the output end of the pressing rod 13, and a mounting seat 16 is fixedly installed on the upper outer surface of the cylinder body 12;

[0030] The rotating assembly includes a wheel disc 9, a pin assembly 17 is arranged inside the wheel disc 9, a bearing is arranged inside the wheel disc 9, and the bearing is fixed on the upper outer surface of the bottom plate;

[0031] The test product includes an inner tooth plate 28 and an outer tooth plate 29. The inner tooth plate 28 is meshed with the inner wall of the outer tooth plate 29. The outer surface of the lower side of the outer tooth plate 29 is provided with test teeth 30. The wheel 9 is sleeved on the outer surface of the outer tooth plate 29. The test teeth 30 are meshed with the pin assembly 17. The lower side of the outer tooth plate 29 is clamped with the center guide sleeve 26, and the lower side of the inner tooth plate 28 is clamped with the top of the first reference 24.

[0032] Working principle: When using the gear center distance detection mechanism, the staff will place the test product to be tested inside the wheel disc 9 of the rotating assembly on the upper side of the base 1, so that the test teeth 30 of the test product's outer tooth plate 29 are meshed with the pin assembly 17 inside the wheel disc 9, and the lower side of the outer tooth plate 29 is clamped with the outer center guide sleeve 26. The center guide sleeve 26 adopts an elastic expansion sleeve structure, so that the error gap of the workpiece itself can be eliminated after the outer tooth plate 29 is clamped, and the lower side of the inner tooth plate 28 is clamped with the top of the first reference 24. After placement is completed, press the switch. The servo motor 8 is started, driving the sliding plate 11 to slide downward along the outer surface of the slide rail 10. The sliding plate 11 slides downward, which drives the clamping assembly fixed at the lower end of the sliding plate 11 to move downward until the pressure head 15 at the lower end of the clamping assembly is in contact with the upper outer surface of the inner tooth plate 28 of the test product. After the connection, the cylinder drives the pressure head 15 to press down again by 3-5CM for different types of test products, so that the compression spring 14 in the cylinder body 12 has elastic force to fix the test product, so as to prevent the inner tooth plate 28 from rotating during the meshing process. After the fixing is completed, because the inner tooth plate 28 is engaged with the first reference 24, the first reference 24 and the two T-blocks 20 are fixedly connected with the elastic body formed by the spring sheet 21, the pressure block 22 and the rivet 23, and because the rivets 23 arranged on the front and rear outer surfaces of the upper T-block 20 are connected with the rivets 23 arranged on the lower side of the base 1 through the tension spring, the rivets 23 on the lower side of the base 1 are fixed, which will exert a rightward pulling force on the rivets 23 arranged on the front and rear outer surfaces of the upper T-block 20, so that the first reference 24 also carries the inner tooth plate 28 has a rightward pulling force, which makes the inner tooth plate 28 close to the right, and the external transmission motor will drive the rotating component to rotate, so that the product keeps meshing and rotating in the direction of measuring the center distance, and measures its center distance change and tooth jump. The changes generated during the test will be transmitted through the first reference 24 to the elastic body composed of two T-blocks 20 and spring sheets 21, pressure blocks 22, and pull pins 23, and the detection sensor 27 is movably fitted with the right side of the upper T-block 20. If there is any fluctuation in the elastic body, the detection sensor 27 will collect the information and transmit it to the computer 4.

[0033] Compared with the related art, the gear center distance detection mechanism provided by the utility model has the following beneficial effects: through the action of the cylinder, the sensor is automatically and cleverly connected to the test workpiece indirectly through the elastic body, and the center distance, full tooth jump and single tooth jump during gear meshing can be automatically measured, the position of the collection sensor is fixed, and the collected data can be automatically saved by the computer. The equipment is fool-proof and has low requirements on the operator's own quality, which can greatly simplify the operator's workload.
