Description

Technical Field

[0001] The utility model relates to the technical field of casting production, in particular to a riser sleeve inspection tool. Background Art

[0002] At present, most of the riser sleeves on the market are cylindrical riser sleeves, which can be used for shrinkage compensation, serving as pouring risers, etc. When the riser sleeve is used for shrinkage compensation, it is necessary to place the riser sleeve on the mold plate, and combine the molding sand with the riser sleeve during molding.

[0003] The roundness of the inner and outer circles of the riser sleeve is an important factor affecting the use effect of the riser sleeve. When the roundness of the inner and outer circles of the riser sleeve is poor, the combination of the riser sleeve and the molding sand is unstable, which may cause the riser sleeve to be damaged and lead to bad mold; it may also cause the riser sleeve to separate from the parting surface, causing sand to fall off the mold plate during subsequent pouring, resulting in defects in the casting, causing waste and increasing production costs.

[0004] Many foundries use vernier calipers to detect the diameter of the riser sleeve, which is laborious and not fast enough. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model proposes a riser sleeve inspection tool to solve the technical problem mentioned in the above background technology that the existing riser sleeve roundness inspection mostly uses a vernier caliper which is not convenient enough.

[0009] The outer circle detection mechanism comprises a plurality of outer circle detection rings with decreasing diameters, the outer circle detection rings are sleeved with each other, the bottom surfaces of the outer circle detection rings are coplanar, and the top surfaces of the outer circle detection rings decrease in height from the outside to the inside.

[0010] Furthermore, adjacent inner circle detection circular plates are detachably connected.

[0011] Furthermore, a limit plate is provided on the bottom surface of the inner circle detection circular plate, and a limit groove is provided on the top surface of the inner circle detection circular plate, so that the limit plate on the inner circle detection circular plate can be inserted into the limit groove of another inner circle detection circular plate at the adjacent bottom, and the limit plate can limit the rotation of the inner circle detection circular plate.

[0012] Furthermore, the side surface of the inner circle detection circular plate is a conical surface.

[0013] Furthermore, the thickness of each inner circle detection circular plate is the same.

[0016] Furthermore, the step differences of the outer circle detection rings are the same.

[0017] Furthermore, the inner circle detection circular plate and the outer circle detection ring are made of hard alloy steel.

[0018] Compared with the prior art, the advancement of this application is:

Specifically, when performing the inner circle detection, the riser sleeve is put on the inner circle detection mechanism.

DETAILED DESCRIPTION

[0026] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0027] Please also read Figure 1-Figure 3 , this embodiment provides a riser sleeve inspection tool, including an inner circle inspection mechanism 1 and an outer circle inspection mechanism 2;

[0028] The inner circle detection mechanism 1 includes a plurality of inner circle detection circular plates 11 with different diameters. Another inner circle detection circular plate 11 is provided on the top surface of the inner circle detection circular plate 11. The diameters of the plurality of inner circle detection circular plates 11 decrease successively from the bottom to the top, and the centers of the inner circle detection circular plates 11 are on the same axis. It should be understood that the inner circle detection circular plates 11 together form a pyramid-like cone.

[0029] The outer circle detection mechanism 2 includes a plurality of outer circle detection rings 21 with decreasing diameters, each outer circle detection ring 21 is sleeved with each other, the bottom surfaces of each outer circle detection ring 21 are coplanar, and the top surfaces of each outer circle detection ring 21 decrease in height from the outside to the inside. That is, another outer circle detection ring 21 is closely attached to the inner wall of the outer circle detection ring 21, each outer circle detection ring 21 is coaxial, and there is a height difference between the top surfaces of adjacent outer circle detection rings 21, and the inner circles of each outer circle detection ring 21 can form a cone.

[0030] In the present application, the inner circle and outer circle of the riser sleeve are respectively detected by the inner circle detection mechanism 1 and the outer circle detection mechanism 2. Specifically, when performing the inner circle detection, the riser sleeve is put on the inner circle detection mechanism 1. If the inner circle of the riser sleeve can be just or with a small gap on the specific inner circle detection circular plate 11 on the inner circle detection mechanism 1, it means that the inner circle roundness of the riser sleeve meets the requirements; when performing the outer circle detection, the riser sleeve is inserted into the outer circle detection mechanism 2. If the riser sleeve is just or with a small gap on the outer circle detection ring required for the specific detection, the roundness of the outer circle of the riser sleeve meets the requirements. Therefore, through one set and one insertion, the roundness of the riser sleeve can be detected more quickly, making the detection more convenient.

[0031] In other schemes, adjacent inner circle detection circular plates 11 are detachably connected. By detachably connecting, replacement can be carried out more conveniently, and when corresponding to different riser sleeves, replacement can be carried out in a targeted manner, so that the application range of the device is wider. As one of the implementation schemes, the top surface of the inner circle detection circular plate 11 is provided with a top mounting groove 111, and another inner circle detection circular plate 11 can be inserted therein for installation. Preferably, it is installed by interference fit, and a side-inserted pin can also be used to limit the lifting and lowering. In addition, other detachable methods should also be considered to be implementable, such as screws, bolts, and side-inserted connecting rods 23. And so on.

[0032] In other schemes, the bottom surface of the inner circle detection circular plate 11 is further provided with a limit plate 12, and the top surface of the inner circle detection circular plate 11 is further provided with a limit groove 112, so that the limit plate 12 on the inner circle detection circular plate 11 can be inserted into the limit groove 112 of another inner circle detection circular plate 11 at the adjacent bottom, and the limit plate 12 can limit the rotation of the inner circle detection circular plate 11. In this way, it can be avoided that it rotates accidentally, making the detection more convenient and avoiding the rotation of the riser sleeve when it is inserted. Preferably, the top surface of the limit plate 12 is lower than the top surface of the limit groove 112 or coplanar, that is, the limit plate 12 will not form a boss on the top surface of the adjacent inner circle detection circular plate 11. It should be understood that the limit plate 12 is not provided on the inner circle detection circular plate 11 of the lowest layer.

[0033] In other embodiments, the side surface of the inner circle detection circular plate 11 is a conical surface. That is, the top surface radius of the inner circle detection circular plate 11 is smaller than the bottom surface radius. Thus, it is easier to insert the riser sleeve. Specifically, the draft angle of the inner circle detection circular plate 11 is consistent with the draft angle of the riser.

[0034] In other solutions, the thickness of each inner circle detection circular plate 11 is the same.

[0035] In other embodiments, the diameters of the inner circle detection circular plates 11 form an arithmetic progression.

[0036] In other solutions, the step differences of the outer circle detection rings 21 are the same, that is, the height of the top of each outer circle detection ring 21 is the same.

[0037] In other schemes, each outer circle detection ring 21 is detachably connected. By detachably connecting, it can be replaced more conveniently. When corresponding to different riser sleeves, it can be replaced in a targeted manner, so that the application range of this device is wider. As one of the implementation schemes, the outer circle detection mechanism 2 also includes a fixed base plate 22, and a bottom mounting groove 221 is provided on the fixed base plate 22. A connecting rod 23 is also provided at the bottom of the outer circle detection ring 21. The connecting rod 23 is inserted into the mounting groove to install each outer circle detection ring 21. The mounting groove and the connecting rod 23 correspond one to one, and the mounting groove is arranged along the radial direction of the outer circle detection ring 21. Specifically, the connecting rod 23 and the bottom mounting groove 221 are interference fit.

[0038] In other solutions, the inner circle detection circular plate 11 and the outer circle detection ring 21 are made of hard alloy steel.

[0039] The riser sleeve inspection tool can more quickly inspect the roundness of the riser sleeve, making the inspection more convenient.
