Existing technologies struggle to meet these functional requirements. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a clamping and detection mechanism, comprising a fixed base plate, a positioning lever structure, a detection rotation structure, a detection lever structure, and a belt tension adjustment mechanism.

[0029] The positioning lever structure is set on the fixed base plate and is used to support the product.

[0030] The detection rotating structure is mounted on a fixed base plate and is used to contact the product detection position;

[0031] The detection lever structure is mounted on a fixed base plate and is used to measure the change in value when the product rotates one revolution.

[0032] The belt tension adjustment mechanism is mounted on the fixed base plate and is used to adjust the tension of the synchronous belt.

[0033] The shock absorber sleeve is centered and fixed by a positioning lever structure. The contact rotation of the shock absorber sleeve is detected by a detection rotation structure, so that the detection lever structure can determine whether the shock absorber sleeve meets the product tolerance requirements.

[0034] The positioning lever structure includes a lever structure, a positioning guide rod, a first positioning contact, a second positioning contact, a coarse guiding cylinder, and a driving clamp. The telescopic connecting rod end of the driving clamp is connected to one end of the lever structure, and the other end of the lever structure abuts against the lower end of the positioning guide rod. The coarse guiding cylinder is vertically installed on the fixed base plate, and the positioning guide rod is installed to slide up and down within the coarse guiding cylinder. The first positioning contact is arranged at the upper end outside the coarse guiding cylinder, and the second positioning contact is arranged at the lower end outside the coarse guiding cylinder.

[0035] Conical blocks are respectively arranged on the positioning guide rod corresponding to the first positioning contact and the second positioning contact. There are multiple first positioning contacts and second positioning contacts arranged in a circle around the coarse guiding cylinder, and the coarse guiding cylinder is provided with an inverted conical surface corresponding to the conical blocks. When the positioning guide rod moves up and down, it can open or retract corresponding to the first positioning contact and the second positioning contact, so as to center and fix the shock absorption sleeve.

[0036] The detection rotation structure includes a bearing, a first gear, a synchronous belt, a second gear, and a rotation handle. The rotation handle is rotatably installed on the fixed base plate through the bearing. The first gear is installed on the rotating shaft of the rotation handle, and the second gear is installed on the rotating end of the detection lever structure. The first gear and the second gear are connected by a synchronous belt.

[0037] The detection lever structure includes a measuring contact, a mounting block, a measuring lever, a transmission rod, a spring, and a Mitutoyo dial indicator. The Mitutoyo dial indicator and the measuring lever are respectively installed on the fixed base plate. The measuring telescopic rod of the Mitutoyo dial indicator abuts against one end of the measuring lever, and a spring is arranged between this end of the measuring lever and the fixed base plate (add a spring to keep the other end, the transmission rod, always upward). The other end of the measuring lever is arranged corresponding to the positioning guide rod. The transmission rod passes through the center of the positioning guide rod. A second gear is arranged at the lower end of the transmission rod. The lower end surface of the transmission rod abuts against one end of the measuring lever close to the positioning guide rod. The upper end of the transmission rod is connected to the center of the mounting block. The measuring contact is arranged on the upper side of the mounting block.

[0038] The rotation of the transmission rod is driven by the second gear to带动 the measuring contact mounting block and the measuring contact installed on the measuring contact mounting block, and finally实现 the rotation of the measuring contact following the manual rotation of the rotation handle;

[0039] When the measuring contact touches the product, the transmission rod will drive the measuring lever downward to make the other end upward, and the value is obtained through the measuring telescopic rod of the Mitutoyo dial indicator. The manual rotation of the detection rotation structure带动 the rotation of the measuring contact. If the interior of the product is uneven, the measuring contact带动 the up and down movement of the transmission rod, which is反馈 to one end of the measuring lever, and the value of the Mitutoyo dial indicator keeps changing. If it is within the tolerance range, the product is qualified.

[0040] The belt tension adjustment mechanism includes a fixed post and an elastic stop. The fixed post is mounted on a fixed base plate, and one end of the elastic stop is connected to the fixed post. The elastic end of the elastic stop contacts the surface of the synchronous belt. The stop, through spring force, always exerts a force in the direction of the synchronous belt, keeping it in a taut state. This makes manual rotation of the handle smoother.

[0041] This technical solution first uses a positioning lever mechanism to manually push the clamps to open positioning contacts one and two, fixing the product and preventing it from wobbling. In the next step, the rotating structure is inspected. The handle is manually rotated, causing the measuring contacts to rotate inside the product. The measuring contacts then move up and down, transmitting data via the measuring lever to a Mitutoyo dial indicator. The product's quality is determined by observing the values ​​on the dial indicator. This mechanism significantly reduces inspection time and improves production efficiency. The Mitutoyo dial indicator also enhances the accuracy and stability of the inspection.

[0042] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
