[0068] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0069] In this article, when it is mentioned that the first component is located on the second component, this may mean that the first component may be directly formed on the second component, or the third component may be interposed between the first component and the second component. In addition, in the drawings, in order to effectively describe the technical content, the thickness of the components may be exaggerated or reduced.

[0070] Herein, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as "at least one of..." modify the entire list of elements when following a list of elements, rather than modifying individual elements in the list.

[0071] The terms used herein are only used to describe specific exemplary configurations and are not intended to be limited. As used herein, the singular articles "one", "an" and "the" may also be intended to include plural forms, unless it is clearly indicated above that this is not the case.

[0073] After research, it was found that the disadvantage of the prior art is that after the valve core is assembled, it is necessary to detect whether the valve core will jump in the radial direction. In the related art, an optical sensor is often used to detect whether the rotating valve core will jump in the radial direction, or a probe is used to contact the outer wall of the valve core to detect whether the valve core will jump in the radial direction.

[0074] However, the above detection methods are all based on the condition that the valve core is not tilted when it is clamped on the detection device. Once it is tilted during clamping, the detection result will inevitably be inaccurate.

[0075] Therefore, how to solve the problem of the valve core tilting during clamping is a technical problem that needs to be solved urgently in this field.

[0076] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0077] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0078] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0079] like Figures 1 to 8 As shown, some embodiments provide a valve core detection device for ASU, including: an operating table 1; a clamping assembly 2, which is arranged on one side of the operating table 1 and is suitable for clamping the sealing disk 34 of the valve core; the clamping assembly 2 includes: a support frame 21, which is arranged on one side of the operating table 1; a vertical moving pair 22, which is arranged on the side wall of the support frame 21; a limit plate 23, which is arranged at the movable end of the vertical moving pair 22, and the end is provided with a groove adapted to the valve core; the limit plate 23 is parallel to the operating table 1 and is arranged above the operating table 1. When the valve core is inserted into the through hole 36, the vertical moving pair 22 drives the limit plate 23 to move downward until the limit plate 23 abuts against the sealing disk 34 of the valve core. The setting of the limit plate 23 avoids axial shaking of the valve core when the driving assembly 3 drives the valve core to rotate circumferentially, thereby improving the detection accuracy. The driving component 3 is arranged at the bottom of the operating table 1 and is suitable for driving the valve core to rotate circumferentially; the detection component 4 is arranged inside the driving component 3 and is suitable for limiting the valve core; wherein, the valve core is inserted into the detection component 4, and the detection component 4 drives the valve core to rotate circumferentially to detect whether the valve core is tilted when inserted; if the valve core is inserted into the detection component 4 in an inclined state, the driving component 3 cannot drive the detection component 4 to rotate. Through the arrangement of the detection component 4, after the valve core is inserted into the detection component 4, the driving component 3 drives the detection component 4 to rotate, and detects whether the valve core is tilted when inserted by detecting whether the detection component 4 can rotate circumferentially relative to the fixed cylinder 33. At the same time, in the process of the detection component 4 rotating circumferentially relative to the fixed cylinder 33, the vertical plate 422 abuts against the outer wall of the positioning ring 38, and the lifting block 43 abuts against the sealing disk 34, which improves the stability of the detection component 4 when it rotates relative to the fixed cylinder 33.

[0080] Reference Figure 1The driving assembly 3 comprises: a driving motor 31, which is arranged below the operating table 1; a transmission disc 32, which is sleeved on the outer wall of the driving shaft and is in transmission connection with the driving motor 31; the driving motor 31 is suitable for driving the transmission disc 32 to rotate circumferentially; the driving shaft is arranged vertically and arranged below the operating table 1; a fixed cylinder 33, which is hollow inside and sleeved on the outer wall of the driving shaft; the driving shaft is suitable for rotating circumferentially relative to the fixed cylinder 33. A sealing disc 34, which covers the upper end of the fixed cylinder 33 and is provided with a through hole 36, and the valve core is suitable for inserting the through hole 36; a positioning disc 35, which is sleeved on the upper end of the driving shaft and is parallel to the sealing disc 34; the positioning disc 35 is rotatably arranged inside the fixed cylinder 33; the detection assembly 4 is arranged at the upper end of the positioning disc 35; and the vertical plate 422 of the detection assembly 4 is suitable for fitting with the inner wall of the positioning cylinder; wherein, when the valve core is inserted into the through hole 36, the detection assembly 4 is suitable for clamping the valve core. The driving motor 31 is suitable for driving the positioning plate 35 to rotate circumferentially, and the positioning plate 35 is suitable for driving the detection assembly 4 to rotate synchronously when rotating. If the valve core is placed vertically, the detection assembly 4 is suitable for driving the valve core to rotate relative to the fixed cylinder 33; while the valve core is placed obliquely, the detection assembly 4 cannot rotate relative to the fixed cylinder 33.

[0081] Reference Figure 4The detection assembly 4 includes: a positioning block 41, which is arranged at the upper end of the positioning disk 35 and extends radially along the positioning disk 35; a gap is provided between the outer end of the positioning block 41 and the inner wall of the fixed cylinder 33; a detection member 42, which passes through the positioning block 41, and the inner end abuts against the outer wall of the valve core; the detection member 42 is suitable for sliding radially along the positioning disk 35 relative to the positioning block 41; preferably, a spring is arranged in the positioning block 41, one end of the spring abuts against the side wall of the detection member 42, and the spring is suitable for pushing the detection member 42 to move toward the axial direction of the positioning disk 35. A lifting block 43 is arranged at the upper end of the positioning block 41 for lifting, and is suitable for abutting against the bottom wall of the sealing disk 34; when the detection member 42 moves outward, it is suitable for pushing the lifting block 43 to move upward until the upper end of the lifting block 43 abuts against the bottom wall of the sealing disk 34. Among them, when the valve core is inserted into the through hole 36, it is suitable for squeezing each detection member 42 to slide outward; the vertical plate 422 of the detection member 42 abuts against the inner wall of the fixed cylinder 33, and the vertical plate 422 is suitable for scraping the grease remaining on the inner wall of the fixed cylinder 33; the lifting block 43 is pushed upward by the detection member 42 to make the grease in the positioning block 41 flow to the outer wall of the valve core; the lifting block 43 abuts against the bottom wall of the sealing disk 34, and when the transmission disk 32 drives the positioning block 41 to rotate circumferentially, the lifting block 43 plays the role of limiting the positioning disk 35, avoiding the shaking of the positioning disk 35 along the axial direction of the driving shaft. The positioning disk 35 rotates circumferentially relative to the fixed cylinder 33 to detect whether the valve core is tilted when inserted into the through hole 36. If the valve core is set at an angle, when the positioning disk 35 rotates circumferentially relative to the fixed cylinder 33, the detection block 423 is suitable for abutting against the limit strip 37 to limit the positioning disk 35 and prevent the positioning disk 35 from rotating.

[0082] Reference Figure 5 The inner bottom wall of the sealing disk 34 is provided with a plurality of limit strips 37 at equal intervals along the circumferential direction. The limit strips 37 are in an arc shape and are arranged between two positioning blocks 41. The limit strips 37 are in an annular shape and a gap is provided between two limit strips 37. The gap is greater than the width of the positioning block 41. If the valve core is inserted into the through hole 36 at an angle, the detection member 42 is adapted to abut against the end wall of the limit strip 37 when the positioning disk 35 rotates circumferentially.

[0083] Furthermore, a positioning ring 38 is provided on the inner bottom wall of the sealing disk 34, and a sliding gap 39 is provided between the inner wall of the positioning ring 38 and the outer wall of the limiting strip 37. The inner diameter of the positioning ring 38 is larger than the outer diameter of the limiting strip 37. The valve core is suitable for pushing the horizontal rod 421 to make the detection block 423 abut against the inner wall of the positioning ring 38, and at this time, the side wall of the vertical plate 422 abuts against the inner wall of the fixed cylinder 33. When the horizontal rod 421 is pushed by the spring to move toward the valve core to clamp the valve core, the vertical plate 422 abuts against the outer wall of the positioning ring 38, and synchronously, the lifting block 43 abuts against the bottom wall of the sealing disk 34.

[0084] Reference Figure 5 The detection member 42 includes: a horizontal rod 421, which is slidably arranged in the positioning block 41, and both ends of the positioning block 41 protrude; a vertical plate 422, which is vertically arranged on the outer end wall of the horizontal rod 421 and slidably arranged between the positioning ring 38 and the fixed cylinder 33; when the horizontal rod 421 slides outward, the vertical plate 422 is suitable for abutting against the inner wall of the fixed cylinder 33, and when the horizontal rod 421 slides inward, the vertical plate 422 is suitable for abutting against the outer wall of the positioning ring 38. A detection block 423 is arranged at the upper end of the horizontal rod 421, and the horizontal height of the upper end is not less than the horizontal height of the bottom wall of the limit strip 37; wherein, the valve core pushes the horizontal rod 421 to slide outward, and the detection block 423 is suitable for sliding into the sliding gap 39 between the positioning ring 38 and the limit strip 37; when the positioning plate 35 rotates circumferentially, the detection block 423 is suitable for sliding in the sliding gap 39 between the positioning ring 38 and the limit strip 37. If the valve core is inserted into the through hole 36 at an angle, at this time, the inner end wall of at least one horizontal rod 421 cannot contact the outer wall of the valve core, or the stroke of the horizontal rod 421 pushed outward by the valve core is smaller than the stroke of the horizontal rod 421 in the normal working state, so that the detection block 423 arranged on the horizontal rod 421 does not slide to the sliding gap 39 between the positioning ring 38 and the limit strip 37. Therefore, when the positioning plate 35 rotates, the detection block 423 abuts against the end wall of the limit strip 37 to limit the rotation of the positioning plate 35.

[0085] Furthermore, the thickness of the detection block 423 is smaller than the sliding gap 39 between the positioning ring 38 and the limiting strip 37 , and the detection block 423 is suitable for sliding between the limiting strip 37 and the positioning ring 38 .

[0086] In order to achieve the effect of greasing the outer wall of the valve core, an oil storage chamber is provided in the positioning block 41, and anti-rust grease is arranged in the oil storage chamber. An oil outlet hole 410 is arranged on the side of the positioning block 41 close to the valve core; the oil outlet hole 410 is connected with the oil storage chamber, and a flow channel is provided on the lifting block 43, and the flow channel is suitable for connecting the oil outlet hole 410 with the oil storage chamber; when the valve core is not inserted into the detection component 4, the lifting block 43 is suitable for closing the oil outlet hole 410; and when the valve core pushes the horizontal rod 421 to move outward, the horizontal rod 421 is suitable for pushing the lifting block 43 to connect the flow channel with the oil storage hole, and the grease in the oil storage chamber is suitable for flowing to the valve core through the oil outlet hole 410. Among them, the lifting block 43 is pushed to move upward until the flow channel is connected with the oil outlet hole 410, and the grease in the oil storage chamber is suitable for flowing to the outer wall of the valve core.

[0087] Furthermore, the inner end wall of the horizontal rod 421 is adapted to the outer wall of the valve core, wherein when the inner end wall of the horizontal rod 421 abuts against the outer wall of the valve core, the inner wall of the vertical plate 422 fits against the outer wall of the positioning ring 38. After the valve core is clamped and limited by the horizontal rod 421, the vertical plate 422 is suitable for abutting against the inner wall of the positioning ring 38. At this time, when the transmission disk 32 rotates circumferentially, the vertical plate 422 abuts against the positioning ring 38, and the lifting block 43 abuts against the bottom wall of the sealing disk 34, preventing the positioning disk 35 from shaking in the axial and radial directions, improving the stability of the transmission disk 32 when rotating, and further improving the detection accuracy of the outer wall of the valve core.

[0088] Optionally, the positioning block 41 has a slide groove in the vertical direction, and the lifting block 43 is lifted and lowered in the slide groove; a compression spring is arranged in the slide groove, one end of the compression spring is arranged on the lifting block 43, and the compression spring is suitable for pushing the lifting block 43 to move downward.

[0089] Some embodiments provide a valve core detection method, including:

[0090] The valve core is vertically inserted into the through hole 36, and the valve core is suitable for squeezing each detection component 4 to make it slide radially outward;

[0091] The limit plate 23 of the clamping assembly 2 moves downward to press the sealing disk 34 of the valve core to prevent the valve core from shaking axially;

[0092] If the valve core is inserted into the through hole 36 in a vertical state, the driving component 3 is suitable for driving the detection component 4 and the valve core to rotate circumferentially;

[0093] If the valve core is inserted into the through hole 36 in a tilted state, the driving component 3 cannot drive the detection component 4 and the valve core to rotate.
