[0017] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified.

[0018] like Figure 1 As shown, the utility model provides a core adhesive detection device, including a detection table 1, a heating table 2 is fixedly installed in the middle of the detection table 1, a heating resistance wire is arranged in the heating table 2, and a core placement groove 4 is opened on the heating table 2, and the shape of the core placement groove 4 is adapted to the shape of the core to be detected. A driving table 3 is arranged on one side of the heating table 2, and the driving table 3 includes a mounting seat 5 and a telescopic cylinder 8. The top of the mounting seat 5 is rotatably inserted and sleeved with a rotating shaft 6, and the top of the rotating shaft 6 is fixedly connected with a rotating table 7. The rotating table 7 rotates relative to the mounting seat 5 under the action of the rotating shaft 6, so that the telescopic cylinder 8 can rotate. The outside of the telescopic cylinder 8 is symmetrically provided with a fixing device, and the telescopic cylinder 8 is fixedly connected to the top of the rotating table 7 through the fixing device, and a limiting device is arranged at the bottom of the outer wall of the rotating shaft 6.

[0019] When in use, the iron core card is placed in the iron core placement slot 4, and the iron core is heated to the required detection temperature by the heating resistance wire, and the telescopic cylinder 8 is started. The side wall of the iron core is pushed by the telescopic cylinder 8. If the connection strength of the bonding part of the iron core is insufficient, the bonding part of the iron core will debond or even break. The bonding strength of the iron core adhesive is tested through the above process.

[0020] like Figure 2 As shown, the limiting device includes a clamping plate 9, which is located inside the mounting seat 5. The bottom of the outer wall of the rotating shaft 6 is slidably inserted and sleeved with the clamping plate 9. The bottom of the clamping plate 9 is fixedly connected with a rotating shaft sleeve 10. The outer wall of the rotating shaft sleeve 10 is provided with a threaded hole. The inner cavity of the threaded hole is threadedly sleeved with a fastening screw 11. A plurality of limiting threaded holes are arranged in depth at the bottom of the rotating shaft 6. After the rotating platform 7 is rotated, the fastening screw 11 can pass through the rotating shaft sleeve 10 and be fixed with the limiting threaded hole at the bottom of the rotating shaft 6, thereby ensuring the stability of the rotating platform 7 after rotation.

[0021] The bottom of the rotating table 7 and the top of the clamping plate 9 are both rotatably embedded with a plurality of balls 12 in a circular array, and the outer walls of the balls 12 are in contact with the mounting seat 5. The balls 12 can reduce the friction between the rotating table 7 and the clamping plate 9 and the mounting seat 5, thereby facilitating the telescopic cylinder 8 to drive the rotating table 7 to rotate, and enabling the driving table 3 to drive the telescopic cylinder 8 to push different positions of the iron core through the rotation of the rotating table 7 in a fixed position, so that the bonding strength test result is more accurate.

[0022] The fixing device includes a limit block 13, the cross section of which is L-shaped, so that the longitude position of the telescopic cylinder 8 can be limited. Four limit screws 14 further limit the latitude position of the telescopic cylinder 8, so as to ensure the stability of the installation of the telescopic cylinder 8. The limit block 13 is slidably engaged with the outer wall of the telescopic cylinder 8, and two limit screws 14 are slidably inserted and sleeved on one side of the top of the limit block 13. The bottom of the outer wall of the limit screw 14 is threadedly inserted and sleeved with the rotating table 7, and the two limit screws 14 are respectively located on both sides of the telescopic cylinder 8.

[0023] The testing platform 1 is provided with mounting holes 16 in four directions of longitude and latitude of the heating platform 2. Mounting blocks 15 are symmetrically fixedly connected to both sides of the mounting seat 5. Connecting bolts are slidably inserted and sleeved on the mounting blocks 15. The mounting blocks 15 and the connecting bolts can fix the mounting seat 5 on the mounting holes 16 of the testing platform 1, and can apply thrust in different directions to the iron core, so that the bonding strength test result is more accurate.

[0025] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
