Specific implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 7 , the present utility model provides a technical solution: a detection device for automatic assembly of a spacer sleeve, including a chute base 1, trapezoidal slides 2 are respectively attached to both ends of the inner wall of the chute base 1, a bidirectional roller rod 3 penetrates through the surface of the trapezoidal slide 2, a bearing seat 4 is fixedly connected to the middle of the inner wall of the chute base 1, an inner diameter detection component 6 is fixedly connected to the top of the bearing seat 4, and an outer diameter detection ring 5 is fixedly connected to the top of the trapezoidal slide 2;

[0025] A plurality of measuring tubes 501 are fixedly connected to the inner wall of the outer diameter detection ring 5, a sliding hole 502 is provided on the surface of the measuring tube 501, a scale line 503 is provided on one side of the sliding hole 502, a touch point 504 is attached to the inner wall of the measuring tube 501, an induction spring 505 is fixedly connected to the bottom of the touch point 504, and a pointer 506 is fixedly connected to one end of the surface of the touch point 504.

[0026] In this embodiment, as Figure 1 , Figure 2and Figure 3 As shown in Figure 3 , one end of the surface of the bidirectional roller rod 3 is provided with a forward thread 301, and the other end of the surface of the bidirectional roller rod 3 is provided with a reverse thread 302. One end of the bidirectional roller rod 3 is fixedly connected to a driving motor 303. The middle part of the surface of the bidirectional roller rod 3 is attached to an intermediate bearing 304. The bidirectional roller rod 3 and the bearing seat 4 form a rotating structure through the intermediate bearing 304. The two ends of the bidirectional roller rod 3 are respectively threadedly connected to the trapezoidal slide seat 2 through the forward thread 301 and the reverse thread 302. This structure can make the trapezoidal slide seat 2 approach or move away from each other by the rotation of the bidirectional roller rod 3, so that the two outer diameter detection rings 5 can approach or move away from each other.

[0027] In this embodiment, as Figure 1 , Figure 2 , Figure 6 and Figure 7 shown, at the top of the inner diameter detection component 6 is fixedly connected to a servo motor 601. At the top of the servo motor 601 is fixedly connected to a balance ring 602. On both sides of the surface of the balance ring 602 are respectively fixed with measuring cylinders 603. At the bottom of the inner wall of the measuring cylinder 603 is fixedly connected to a buffer spring 604. One end of the buffer spring 604 is fixedly connected to a contact pin 605. The surface of the measuring cylinder 603 is provided with a through observation window 606. The contact pin 605 and the measuring cylinder 603 form an elastic structure through the buffer spring 604. This structure can judge whether the inner wall of the spacer sleeve meets the standard by the depth of the contact pin 605 entering the measuring cylinder 603.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the measuring tubes 501 are evenly distributed on the inner wall of the outer diameter detection ring 5, and the two groups of measuring tubes 501 are symmetrically arranged with each other. This structure facilitates the contact points 504 to contact all parts of the outer wall of the spacer sleeve.

[0029] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the pointer 506 penetrates the surface of the measuring tube 501, and the pointer 506 and the contact point 504 form an integral structure. When the contact point 504 is squeezed into different depths of the measuring tube 501, this structure can drive the pointer 506 to point to different scale lines 503.

[0030] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the touch point 504 and the measuring tube 501 form an elastic structure through the induction spring 505. This structure enables the touch point 504 to exert different pressures on the induction spring 505 when contacting different positions on the outer wall of the spacer sleeve, thereby causing the touch point 504 to enter the measuring tube 501 to different depths.

[0031] The usage method and advantages of the present utility model: For this detection device for automatic assembly of the spacer sleeve, during use, the working process is as follows:

[0032] As Figures 1 - 7 shown, first, the spacer sleeve to be detected is sleeved on the inner diameter detection component 6. After starting the drive motor 303, when the drive motor 303 rotates, it drives the bidirectional roller rod 3 to rotate together. At this time, the two sets of trapezoidal sliders 2 will move relative to each other along the chute base 1 until the touch point 504 contacts the outer wall of the spacer sleeve to be detected. Through the contact between each touch point 504 and the outer wall of the spacer sleeve, the touch point 504 is inserted into the inner wall of the measuring tube 501 to a certain depth. The value of the scale line 503 pointed to by the pointer 506 can be used to determine whether the outer wall of the spacer sleeve contacted by this touch point 504 is the same as other positions. If the values are different, it means that the thickness of the outer wall of the spacer sleeve at this place is different from other positions and needs to be marked and reprocessed and polished; start the servo motor 601 to make the balance ring 602 drive the measuring cylinder 603 to rotate. At the same time, the contact needle 605 will slide along the inner wall of the spacer sleeve. If there are uneven positions on the inner wall of the spacer sleeve, it can be observed from the observation window 606 that the contact needle 605 is squeezed into the measuring cylinder 603 to different depths, thereby detecting the positions where the inner wall size of the spacer sleeve does not meet the standard or the surface is uneven.

[0033] The above shows and describes the basic principles, main features, and advantages of the present utility model. Technical staff in this industry should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
