[0033] It should be noted that the features in the embodiments of the utility model can be combined with each other without conflict.
[0034] As the background art, in the chain production process, usually a plurality of inspection procedures are carried out to ensure that the accuracy of the pipe part meets the requirements involved. The existing chain plate usually adopts artificial holding gauge for detection, which is inconvenient for positioning and easy to be injured, thereby affecting the service life.
[0035] Please refer to Figures 1-3 The ladder pin hole inspection tool 100 and the chain plate inspection system provided in the embodiments of the utility model can solve the above problems, which will be described in detail.
[0036] In a first aspect, the embodiments of the utility model further provide a ladder pin hole inspection tool 100 for a chain plate inspection system, which comprises a limiting block 110 and a core rod 120.
[0037] The limiting block 110 is used for being installed on the chain plate, the limiting block 110 is provided with a limiting hole 111, the core rod 120 comprises a limiting section 121 and an inspection section 122 arranged coaxially, the limiting section 121 is accommodated in the limiting hole 111, and the inspection section 122 is used for being inserted into the ladder pin hole.
[0038] When the inspection operation is carried out, the limiting block 110 can be installed on the chain plate to improve the positioning accuracy, and the limiting section 121 is accommodated in the limiting hole 111 to ensure the accuracy of the inspection section 122, thereby avoiding injury and improving the service life.
[0039] In the embodiment, the limiting block 110 is in the shape of a cuboid, and the limiting hole 111 is provided at the center of the opposite two faces of the limiting block 110, so that the limiting block 110 will not be skewed due to uneven stress when accommodating and bearing the core rod 120. Of course, in other embodiments of the utility model, the limiting block 110 can be in the shape of a cylinder, a circular truncated cone or a prism, and the specific shape of the limiting block 110 is not limited. In addition, the number of limiting holes 111 on a single limiting block 110 can be two, three, five or eight, and the specific number of limiting holes 111 is not limited.
[0040] In the embodiment, the cross-sectional shape of the limiting hole 111 is circular, and the cross-sectional shape of the corresponding limiting section 121 is also circular; in other embodiments of the utility model, the cross-sectional shape of the limiting hole 111 and the limiting section 121 can also be rectangular, triangular or other shapes.
[0041] It should be noted that, because the cross-sectional shape of the stepped pin hole is usually circular, the inspection section 122 needs to be adapted to the stepped pin hole, and the cross-sectional shape thereof is also circular.
[0042] Reference Figures 1-3 The outer wall of the limiting block 110 forms a limiting boss 112, which is used in cooperation with the chain plate.
[0043] In the embodiment, the limiting boss 112 is in the shape of a cuboid, and the limiting boss 112 can be regarded as being arranged protruding from the bottom surface of the limiting block 110, two side surfaces of the limiting boss 112 are flush with two side surfaces of the limiting block 110, the front surface of the limiting boss 112 is arranged vertically to the bottom surface of the limiting block 110, and the rear surface of the limiting boss 112 is flush with the rear surface of the limiting block 110. By limiting the external shape of the boss, the forming convenience of the limiting boss 112 can be improved.
[0044] It should be noted that the limiting boss 112 can be integrally formed with the limiting block 110, of course, the two can also be welded, bonded or detachably connected, and the specific detachable connection modes include but are not limited to threaded bolt connection, buckle connection, bolt connection and the like.
[0045] In addition, in other embodiments of the utility model, the limiting boss 112 can be in the shape of a truncated cone, and the front surface thereof can be arranged at an angle to the bottom surface of the limiting block 110, which can be an acute angle or an obtuse angle. The specific external shape of the limiting boss 112 is not limited.
[0046] It should be noted that, in order to ensure the relative position stability of the limiting boss 112 and the mandrel 120, the extension direction of the limiting boss 112 can be parallel to the extension direction of the limiting hole 111 for accommodating the mandrel 120.
[0047] Reference Figure 2 And Figure 3 In order to improve the structural stability of the whole mandrel 120, the outer diameter of the limiting section 121 can be greater than the outer diameter of the inspection section 122.
[0048] It is worth noting that, because the stepped pin holes to be inspected usually have different inner diameter sizes, the inspection section 122 can also have multiple outer diameter sizes to match the stepped pin holes. In the case of an integral core rod 120, the entire core rod 120 needs to be replaced synchronously when inspecting stepped pin holes of different inner diameters; while in the case of a detachable split core rod 120, the inspection section 122 only needs to be replaced when inspecting stepped pin holes of different inner diameters, greatly improving the convenience of inspection operations for different stepped pin holes.
[0049] Moreover, the cross-sectional shape of the inspection section 122 and the cross-sectional shape of the limiting section 121 are both circular, that is, from the side of the limiting block 110, the projections of the inspection section 122 and the limiting section 121 on the side of the limiting block 110 are two concentric circles.
[0050] Reference Figures 1-3 In order to avoid the obvious step between the limiting section 121 and the inspection section 122 with different outer diameters from being easily broken, the limiting section 121 and the inspection section 122 can be formed with a transition section 123, and the outer diameter of the transition section 123 gradually decreases in the direction close to the inspection section 122.
[0051] It can be understood that, the outer diameter of one end of the transition section 123 close to the limiting section 121 is the same as that of the limiting section 121, and the outer diameter of one end of the transition section 123 close to the inspection section 122 is the same as that of the inspection section 122, thereby making the inspection section 122 and the limiting section 121 have structural continuity at the connection, which helps to improve the connection strength of the two.
[0052] In this embodiment, the axial cross-section of the transition section 123 is isosceles trapezoidal, that is, the two sides thereof can be approximately regarded as inclined planes, that is, the slope of the outer wall of the transition section 123 in the direction from the limiting section 121 to the inspection section 122 is consistent.
[0053] Of course, in other embodiments of the present application, the two sides of the axial cross-section of the transition section 123 can be arc surfaces, that is, the curvature of the outer wall of the transition section 123 in the direction from the limiting section 121 to the inspection section 122 gradually changes, specifically, the curvature of the outer wall of the transition section 123 in the direction from the limiting section 121 to the inspection section 122 can gradually decrease, or the curvature of the outer wall of the transition section 123 in the direction from the limiting section 121 to the inspection section 122 can gradually increase.
[0054] It is worth noting that, in order to improve the detection efficiency and facilitate inspection operations at both ends of the limiting section 121, the number of inspection sections 122 can be two, and the two inspection sections 122 are connected to the two ends of the limiting section 121 respectively.
[0055] The embodiment of the utility model provides a chain chain plate inspection system, including above-mentioned echelon pin hole inspection tool 100, still include chain chain plate and other inspection tool, specifically include but not limited to lubrication inspection tool, tension force inspection tool and appearance inspection tool. The chain chain plate inspection system includes echelon pin hole inspection tool 100, it has echelon pin hole inspection tool 100's all functions.
[0056] In conclusion, the echelon pin hole inspection tool 100 and chain chain plate inspection system provided by the embodiment of the utility model at least have the following advantages:
[0057] (1), the echelon pin hole inspection tool 100 can be installed in chain chain plate by limiting block 110 to improve positioning accuracy, and the accuracy of the inspection section 122 is ensured by accommodating the limiting section 121 in the limiting hole 111, and further avoid the collision, improve the service life.
[0058] (2), the echelon pin hole inspection tool 100 can be set by setting the transition section 123 between the limiting section 121 and the inspection section 122, and the outer diameter of the transition section 123 gradually decreases along the direction close to the inspection section 122, and the transition section 123 plays a role between the limiting section 121 and the inspection section 122 with different outer diameters, and further avoid the limiting section 121 and the inspection section 122 because of the existence of obvious step because of the difference in outer diameter and easy to break.
[0059] (3), the echelon pin hole inspection tool 100 can be formed by protruding the limiting boss 112 on the bottom surface of the limiting block 110, and the limiting boss 112 is used to cooperate with the chain chain plate, so as to improve the relative position stability of the chain chain plate during the inspection operation.
[0060] The above is only a specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
