DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 5The embodiment of the utility model provides a motor comprehensive static detection device, comprising: a detection platform 1, a mounting frame 2, an electrical detection pen 3 for electrically connecting to an external multimeter, a support mechanism 4 for supporting the mounting frame 2, and a limiting mechanism 5, wherein the mounting frame 2 is arranged above the detection platform 1, and the electrical detection pen 3 is installed in the inner cavity of the mounting frame 2. The resistance, DC voltage and capacitance of the motor can be measured by using the multimeter in conjunction with the electrical detection pen 3, and the limiting mechanism 5 is arranged on the supporting mechanism 4; the limiting mechanism 5 comprises a bracket 51 arranged on one side of the supporting mechanism 4, and the inner cavity of the bracket 51 is slidably connected with a limiting block 52 for limiting the local components of the supporting mechanism 4, and one side of the limiting block 52 movably penetrates into the interior of the supporting mechanism 4, and the inner wall surface of the bracket 51 is fixedly connected with a second spring 54, and the other end of the second spring 54 is fixedly connected to one side of the limiting block 52, and a guide member 55 is arranged between the bracket 51 and the limiting block 52.

[0029] There is one support mechanism 4 on each side of the mounting frame 2 , and the two support mechanisms 4 are symmetrically arranged on the top of the testing platform 1 , and the bracket 51 is arranged on the outer surface of one of the support mechanisms 4 .

[0030] Among them, the supporting mechanism 4 includes a pillar 41 fixedly connected to the top of the testing platform 1, a slide groove 42 is opened on the side of the pillar 41 close to the electrical testing pen 3, the inner cavity of the slide groove 42 is slidably connected with a slider 43, one side of the slider 43 is fixedly connected to the mounting frame 2, and the top of the slider 43 is fixedly connected with a first spring 44, the top of the first spring 44 is fixedly connected to the inner wall surface of the pillar 41, and the bracket 51 is fixedly connected to the outer surface of one of the pillars 41. By moving the mounting frame 2, the mounting frame 2 can drive the slider 43 to move up and down in the inner cavity of the slide groove 42, and then can guide the moving direction of the mounting frame 2, which helps to ensure that the mounting frame 2 can move up and down stably. Through the elastic force of the first spring 44, the mounting frame 2 can be automatically reset for the next use.

[0031] Among them, the inner cavity of the slider 43 is movably penetrated by the slider 43, and both ends of the slider 43 are fixedly connected to the inner wall surface of the slide groove 42. The first spring 44 is sleeved on the surface of the guide rod 45. The guide rod 45 can limit the first spring 44, so that the reverse elastic force generated by the first spring 44 during stretching can always be in the same straight line with the direction of the pulling force, thereby avoiding the first spring 44 from being skewed.

[0032] Among them, the top of the limit block 52 contacts the bottom of one of the sliders 43, and a through hole 53 for the limit block 52 to pass through is opened on one of the pillars 41. The limit block 52 can play a limiting and blocking role on the slider 43, effectively preventing the slider 43 from moving downward when not in use.

[0033] Among them, a slope 521 is set at the bottom of the limit block 52, and the horizontal line on the left side of the slope 521 is higher than the horizontal line on the right side. When the slider 43 moves upward, the slider 43 squeezes the limit block 52 through the slope 521, and uses the slope 521 to change the force direction, so as to realize the mutual conversion of the force direction of the limit block 52 from the vertical direction to the horizontal direction, so that the hand does not need to operate the limit block 52 when the slider 43 moves upward, thereby achieving the purpose of quickly limiting the slider 43.

[0034] Among them, both the front and rear sides of the limit block 52 are integrally formed with protrusions 522, and the protrusions 522 are used to facilitate the staff to move the limit block 52.

[0035] Among them, the guide member 55 includes a guide column 551 fixedly connected to the inner wall surface of the bracket 51, and a guide groove 552 is provided on the limit block 52 for the guide column 551 to pass through. The second spring 54 is sleeved on the surface of the guide column 551. Through the coordinated use of the guide groove 552 and the guide groove 552, the limit block 52 can be guided, so that the limit block 52 can stably move along the axial direction of the guide column 551.

[0036] Among them, a sliding hole 553 is opened on one side of the inner cavity of the guide groove 552, and a stopper 554 is slidably connected to the inner cavity of the sliding hole 553. One side of the stopper 554 is fixedly connected to one end of the guide column 551. The diameter of the stopper 554 is larger than the diameter of the guide column 551. Through the coordinated use of the sliding hole 553 and the stopper 554, a blocking effect can be played on the limit block 52, effectively preventing the limit block 52 from slipping off the surface of the guide column 551.

[0037] A clamping mechanism 6 for clamping and fixing the electrode is installed on the top of the detection platform 1 .

[0038] It should be noted that the working principle of the above-mentioned mounting frame 2 is consistent with the movable plate, electric push rod and mounting block in a motor comprehensive performance test and detection equipment disclosed in the existing announcement number CN218675225U, and the working principle of the above-mentioned electrical detection pen 3 and the clamping mechanism 6 is consistent with the electrical detection pen main body and the clamping mechanism in a motor comprehensive performance test and detection equipment disclosed in the existing announcement number CN218675225U, which are all existing technologies and will not be repeated in this technical solution.

[0039] The working principle of the utility model is as follows: the motor placed on the test platform 1 is clamped and fixed by the clamping mechanism 6, and then the convex block 522 is used to toggle the limit block 52, so that the limit block 52 drives the guide groove 552, the sliding hole 553 and the inclined surface 521 to move synchronously, and the limit block 52 slides on the surface of the guide column 551 and the stopper 554, and the limit block 52 also slides in the inner cavity of the through hole 53, and the second spring 54 is compressed until the limit block 52 is separated from the inner cavity of the sliding groove 42, and the corresponding slider 43 can be unlocked. At this time, the mounting bracket 2 can be pressed downward, so that the mounting bracket 2 drives the electrical detection pen 3 and the slider 43 to move downward synchronously, and the slider 43 slides in the inner cavity of the sliding groove 42 and the surface of the guide rod 45, and the first spring 44 is stretched until the electrical detection pen 3 and the slider 43 are separated. The testing pen 3 contacts the motor for testing. After the testing is completed, the mounting frame 2 is released, and the slider 43, the mounting frame 2 and the electrical testing pen 3 can be driven to move upward by the elastic force of the first spring 44. One of the sliders 43 uses the inclined surface 521 to squeeze the limit block 52, and uses the inclined surface 521 to change the force direction, so as to realize the mutual transformation of the force direction of the limit block 52 from the vertical direction to the horizontal direction, so that the limit block 52 automatically moves toward the inner cavity of the bracket 51 until the slider 43 moves to the top of the limit block 52. At this time, the limit block 52 is reset by the elastic force of the second spring 54, so that the limit block 52 is located at the bottom of the slider 43, thereby completing the limiting operation of the mounting frame 2, the electrical testing pen 3 and the corresponding slider 43.
