[0019] Below, embodiments of the present invention are described in detail with reference to the accompanying drawings. To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying 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.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the present invention for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0021] Example 1

[0022] like Figure 1-Figure 4 As shown, the bushing adhesion detection equipment in this embodiment mainly includes a mounting frame 10, a driving part 20, a positioning part 30 and a detection part 50. The driving part 20 is used to drive the lifting movement of the positioning part 30. The positioning part 30 is used to install the bushing 40 to be detected. The bottom of the mounting frame 10 is provided with the detection part 50. The driving part 20 is arranged at the top of the mounting frame 10 and faces the detection part 50. The positioning part 30 is driven by the driving part 20 and then drives the bushing 40 to enter the detection part 50 for the adhesion effect test.

[0023] Here, the driving unit 20 may be a linear driving mechanism such as an air cylinder, a hydraulic cylinder, or an electric push rod.

[0024] Specifically, the mounting frame 10 includes a bottom plate 11 , a top plate 12 , and a support column 13 disposed between the top plate 12 and the bottom plate 11 .

[0025] In addition, the detection part 50 includes a base 60 and a detection block 70 detachably arranged on the base 60, a first through hole 61 is longitudinally penetrated on the base 60, a second through hole 71 is longitudinally penetrated on the detection block 70, the first through hole 61 is connected to the second through hole 71, the diameter of the second through hole 71 is smaller than the diameter of the first through hole 61, and the second through hole 71 is for the bushing 40 to pass through.

[0026] Among them, one side end surface of the base 60 is recessed inward to form a positioning groove 62, and the detection block 70 is inserted and set in the positioning groove 62 and cannot pass through the positioning groove 62, that is, the detection block 70 is just embedded in the positioning groove 62, and is taken in and placed by plugging and unplugging, and the detection block 70 of the corresponding specification can be replaced.

[0027] Among them, a limiting step 72 is provided inwardly protruding in the second through hole 71, and the limiting step 72 divides the second through hole 71 into a first hole body 73 and a second hole body 74. The diameter of the first hole body 73 is larger than the diameter of the second hole body 74, and the first hole body 73 is located above the second hole body 74.

[0028] Correspondingly, the bushing 40 includes an inner core 41, a rubber sleeve 42 and an outer tube body 43 which are arranged in sequence from the inside to the outside. The outer diameter of the outer tube body 43 matches the first hole body 73, and the outer tube body 43 cannot pass through the limiting step 72 to enter the second hole body 74. Therefore, by pressing down the bushing 40, a separation force can be generated between the outer tube body 43 and the rubber sleeve 42, so that whether the bonding effect between the two meets the standard can be detected by observing whether cracking and debonding occur.

[0029] At the same time, the positioning part 30 includes a connecting rod 31 and a positioning rod 32. The connecting rod 31 is connected to the driving part 20. The positioning rod 32 is used to insert the inner core 41. The positioning rod 32 has protruding and spirally distributed friction protrusions 321. The friction protrusions 321 can improve the tightness of the insertion with the bushing 40 and improve the connection effect.

[0030] Example 2

[0031] In this embodiment, an LED light bar 80 can be attached to the support column 13 and electrically connected to an external power source. The LED light bar 80 is disposed toward the detection portion 50 and can provide lighting to improve manual observation effects.

[0032] When the utility model is in use, debugging blocks of different sizes, shapes and other specifications can be processed to form corresponding test bushing structures. By performing performance tests on bushing structures equipped with different debugging blocks, debugging blocks of optimal specifications can be quickly selected according to the test structures, and batch production can be carried out.

[0033] All the methods described herein can be performed in any suitable order. Any and all examples used, or exemplary language provided herein (such as "for example") are merely to better illustrate the present invention, and are not intended to limit the scope of the present invention, unless the claims are included.
