Example

[0022] The bearing parts need to be fixed by manual clamps, and then the outer ring of the bearing needs to be constantly manually turned during the detection process, so that multiple internal steel balls can rotate, which is convenient for negative clearance detection at multiple points on the outer side of the outer ring. However, this results in high labor intensity of manual labor, especially manual turning, which is very inconvenient.

[0023] To do this, see Figure 1-3 The utility model provides a negative clearance detection steel ball toggle assembly, comprising: a detection platform 1 and a negative clearance detector 2 fixed to the top of the detection platform 1, and a positioning structure 3 for fixing the bearing member is also installed on the top of the detection platform 1;

[0025] It also includes an adjustable toggle structure 4, which is installed on the top of the test bench 1 and connected to the positioning structure 3. The adjustable toggle structure 4 can be linked to the outer side of the bearing part during the process of the positioning structure 3 fixing the bearing part, and is convenient for the subsequent toggle of the bearing part.

[0026] Further Figure 1-3 As shown, it is worth explaining in detail that in order to facilitate the fixing of bearings of different diameters and sizes, a positioning structure 3 is provided, including a concave cavity opened at the top of the testing platform 1, and the inner bottom wall of the concave cavity is rotatably connected to a bevel gear b35 through a rotating shaft, and the upper part of the bevel gear b35 is meshedly connected with three bevel gears a34 arranged in a ring array, and the mounting shaft holes of the bevel gear a34 are all fixedly connected to the outer side of the extension part of one end of the screw rod 33, and the screw rod 33 is threadedly connected to the slider 32, and the slider 32 is slidably connected to the slide groove provided at the top of the testing platform 1, and the top of the slider 32 is fixedly connected with an L-shaped positioning seat 31, and the end of the screw rod 33 in the slide groove vertically arranged with the negative clearance detector 2, away from the concave cavity, extends to the outside of the testing platform 1, and is fixedly connected with a handle 36.

[0027] The L-shaped positioning seat 31 can support the bottom of the inner ring of the bearing, and when the three L-shaped positioning seats 31 move away from the concave cavity at the same time, the bearing can be positioned.

[0028] Further Figure 1-3 As shown, it is worth specifically explaining that, in order to facilitate the use and adjustment of bearings of different sizes, an adjustable toggle structure 4 is provided, including an inverted L-shaped adjusting rod 41, and the inverted L-shaped adjusting rod 41 is parallel to a vertically arranged slide groove of the negative clearance detector 2, and the inverted L-shaped adjusting rod 41 is movably inserted into the L-shaped positioning seat 31 provided at the slide groove, and a hand screw 411 is threadedly connected to one side wall of the L-shaped positioning seat 31 provided at the slide groove, and one end of the hand screw 411 after being locked will be pressed against the outer side of the inverted L-shaped adjusting rod 41, and a moving block 42 with a convex structure in vertical cross section is fixedly connected to the bottom end of the inverted L-shaped adjusting rod 41, and the moving block 42 is slidably connected to the detection table 1, a micro motor 43 is fixedly connected to the inner top wall of the inverted L-shaped adjusting rod 41, the output shaft of the micro motor 43 penetrates the inverted L-shaped adjusting rod 41, and is fixedly connected to a tray 44, a cross-shaped vertical block 45 is fixedly connected to the center of the top of the tray 44, a toggle wheel 46 is provided on the outer movable sleeve of the cross-shaped vertical block 45, a cross-shaped matching groove 47 matching with the cross-shaped vertical block 45 is provided on the toggle wheel 46, a clamping block 48 with an I-shaped structure in vertical section is slid in the I-shaped channel provided at the top protruding part of the cross-shaped vertical block 45, one end of the clamping block 48 is provided with an inclined surface, and the other end is connected to the inner wall of the I-shaped channel through a spring 410, and a push block 49 is fixedly connected to the top of the clamping block 48.

[0029] Among them, by loosening the hand-screw 411, the inverted L-shaped adjustment rod 41 can be movably adjusted on its L-shaped positioning seat 31, so as to adjust the distance between the toggle wheel 46 and the L-shaped positioning seat 31, thereby facilitating the positioning and toggling of bearings of different diameters, greatly improving its scope of application. In addition, by pushing the block 49 to push the clamping block 48 to compress its spring 410, one end of the inclined surface is retracted into the I-shaped channel, thereby facilitating the removal of the toggle wheel 46 for replacement.

[0030] In summary: when using the negative clearance detection steel ball toggle assembly, the inner ring of the bearing can be placed on the three L-shaped positioning seats 31, and the screw 33 is rotated by the handle 36. Then, in conjunction with the setting of the bevel gear a34 and the three bevel gears b35, the three screws 33 are rotated in the same direction, so that the three L-shaped positioning seats 31 move synchronously away from the direction of the concave cavity, and then the three L-shaped positioning seats 31 fix the inner ring of the bearing. In addition, the detachable toggle wheel 46 on the output shaft of the micro motor 43 on the inverted L-shaped adjusting rod 41 is driven to approach and fit the outer side of the outer ring of the bearing. When the micro motor 43 is started, the toggle wheel 46 can be prompted to toggle the outer ring of the bearing, prompting the outer ring to be fixed on the inner ring through multiple steel balls, thereby facilitating the negative clearance detector 2 to detect multiple points on the outer side of the bearing, thereby greatly improving the detection efficiency.
