Description

Technical Field

[0001] The utility model belongs to the technical field of support roller detection, and particularly relates to a support roller conical surface measuring device. Background Art

[0002] To facilitate the removal and installation of rolling mill bearings, support rollers utilize tapered oil-film bearings, and the taper of the left and right journals is typically designed to a ratio of 1:5 or 1:5.647058 during machining. This taper design significantly reduces friction and wear, improves rolling accuracy, extends equipment life, and ensures rolling process stability and product quality. Consequently, it has been widely used in industries such as steel and metallurgy, achieving excellent results. Because the support roller journals mate with the tapered bearings, the taper of the journal surface must be precisely controlled. Therefore, the taper of the support roller's tapered surface must be tested during production and before installation.

[0003] The taper template is a common scale for measuring the taper of support rollers (i.e., the taper of the support roller journal). It is usually used in conjunction with a spacer. Specifically, the spacer is fixed to the top of the taper template. During measurement, the free end of the spacer is aligned with the shoulder end of the support roller. Then, one side of the taper template is placed against the tapered surface of the support roller. The parallelism between the other side of the taper template and the tapered surface of the support roller is measured.

[0004] However, in the prior art, the distance rod and the taper template are fixedly connected together to form a measuring component, which means that a measuring component can only be used to measure cones within a specific length. For longer cones, only longer taper templates can be made. Therefore, there are certain limitations in use. Utility Model Content

[0041] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0042] Example:

[0043] The support roller cone surface measuring device provided in this embodiment is as follows: Figure 1-Figure 5 As shown, it includes a taper template 100, a connecting portion 200 and a distance rod 300, wherein:

[0044] The taper template 100 is the same as the prior art, having a cone top and a cone bottom. The connecting part 200 is connected to the cone top of the taper template 100. The distance rod 300 is detachably fixedly installed on the connecting part 200, and the axial direction of the distance rod 300 is parallel to the length direction of the taper template 100. In addition, there are multiple distance rods 300, and the lengths of the multiple distance rods 300 are different. One of the multiple distance rods 300 is installed on the connecting part 200.

[0045] When in use, first determine the appropriate length of the distance rod 300 according to the length of the support roller conical surface. If the length of the support roller conical surface is shorter, install the shorter distance rod 300 on the connecting part 200, and then measure; if the length of the support roller conical surface is longer, first install the shorter distance rod 300 on the connecting part 200, so as to measure a length of the conical surface first, and then remove the shorter distance rod 300 and install the longer distance rod 300, so that the taper template 100 can be made farther away from the free end of the distance rod 300, so that the remaining conical surface can be measured using the device.

[0046] Through the above structure, in the support roller cone surface measuring device provided by this embodiment, the distance rod 300 is detachably mounted on the connecting part 200, and the connecting part 200 is further mounted on the cone top of the cone template 100. Therefore, the distance rod 300 of different lengths can be replaced as needed, so that the measuring device can measure cones with longer lengths, that is, the measuring device can measure cones in a wider range and is more practical. In this way, when measuring a longer cone length, it is only necessary to select a longer distance rod 300, and there is no need to make a large-sized cone template, which makes the measurement of the cone surface more convenient.

[0047] It should be noted that the "conical surface measurement" described in this embodiment refers to measuring the taper at various locations on the support roller's conical surface. Under optimal conditions, the taper at various locations on the support roller's conical surface is the same. When measuring using the taper template 100, the free end face of the distance rod 300 is first placed against the shoulder end face of the support roller. The conical surface of one side of the taper template 100 is then brought into close contact with the conical surface. A micrometer is then used to measure the distance between the conical surface on the other side of the taper template 100 and the other conical surface on the support roller at various locations. If the measured distances at each location are the same, the taper of the conical surface meets the requirements; otherwise, it does not meet the requirements. Of course, this measurement method is prior art, so it will not be described in detail here.

[0048] An optional implementation of this embodiment is as follows: the connecting portion 200 includes a connecting plate 210 and a sleeve 220, wherein:

[0049] The connecting plate 210 is detachably fixedly connected to the top of the taper template 100, and the sleeve is fixedly connected to the connecting plate 210. The distance rod 300 is inserted into the sleeve 220 and locked by a locking assembly, thereby making the distance rod 300 detachably fixedly connected to the connecting portion 200. When the locking assembly is locked, the distance rod 300 is firmly connected to the connecting portion 200. When the locking assembly is unlocked, the distance rod 300 can be removed from the connecting portion 200. Of course, the connecting portion 200 and the distance rod 300 in this embodiment can also be connected together by a fixed connection method such as welding.

[0050] To achieve a removable connection between the taper template 100 and the connecting portion 200, in this embodiment, a connecting piece 110 is integrally formed at the conical top of the taper template 100. Two connecting pieces 210 are provided, and one section of each connecting piece 210 is welded, hot-melt-connected, or adhesively fixed to the outer wall of the sleeve 220. The two connecting pieces 210 are arranged in parallel and on the same side of the sleeve, forming a sandwich between the two connecting pieces 210. The connecting piece 110 is inserted into the sandwich and locked by a fastening assembly. When the fastening assembly is locked, the connecting piece 110 and the fastening assembly securely connect the connecting piece 210 to the taper template 100. When the fastening assembly is unlocked, the connecting piece 110 can be removed from the connecting piece 210. Alternatively, there can be only one connecting piece 210, and the connecting piece 110 and the connecting piece 210 can be stacked and connected via a screw and nut pair.

[0051] Optionally, the fastening assembly includes a bolt 400 and a first nut 500. A through-hole is provided in the connecting plate 210, and a through-hole is provided in the connecting piece 110. The bolt 400 passes through the through-hole and the through-hole and is then threadedly engaged with the first nut 500. Thus, the first nut 500 and the nut cap of the bolt 400 clamp the two connecting plates 210 and the connecting piece 110 therebetween, thereby achieving locking. Alternatively, the fastening assembly in this embodiment may be a stop screw. A threaded through-hole is provided in the connecting plate 210, and the stop screw is threadedly engaged in the threaded through-hole. When tightening, the stop screw presses against the outer wall of the connecting piece 110.

[0052] More preferably, the thickness of the connecting piece 110 in this embodiment is less than the thickness of the tapered template 100, and the connecting piece 110 is fixed at the middle position of the cone top of the tapered template 100 to form a clearance gap 120 between the two plate surfaces of the connecting piece 110 and the two plate surfaces of the tapered template 100. The clearance gap 120 is adapted to the connecting plate 210, and the two connecting plates 210 are respectively accommodated in the two clearance gaps 120, thereby making the structure more compact.

[0053] In order to make the connecting piece 110 more firmly connected between the two connecting plates 210, in this embodiment, the number of the above-mentioned via holes and the above-mentioned through holes is multiple, and the multiple above-mentioned via holes and the multiple above-mentioned through holes correspond one to one to form a plurality of connecting holes, and each of the above-mentioned connecting holes is installed with the above-mentioned fastening component.

[0054] Optionally, in this embodiment, a positioning member is further installed between the connecting piece 110 and the connecting plate 210 so that the connecting piece 110 and the connecting plate 210 can be installed more accurately. Optionally, the positioning member in this embodiment is a positioning pin 600, a first pin hole is provided on the connecting piece 110, and a second pin hole is provided on the connecting plate 210. The positioning pin 600 is pinned to the first pin hole and the second pin hole, and the positioning pin 600 can be disassembled from the first pin hole and the second pin hole. Of course, the positioning member can also be a positioning protrusion provided on the connecting piece 110, a corresponding positioning groove is provided on the connecting plate 210, and the positioning protrusion is inserted into the positioning groove, thereby positioning the position of the connecting piece 110 in the above-mentioned interlayer.

[0055] An optional implementation of this embodiment is as follows: the above-mentioned distance rod 300 is a straight rod body, and the middle part of the distance rod 300 is integrally formed with a protrusion 310 protruding from its outer wall. The two ends of the straight rod body are defined as the first end and the second end respectively. The end face of the first end is a plane. When in use, the end face of the first end is in close contact with the end face of the support roller shoulder. The partial section of the above-mentioned straight rod body between the protrusion 310 and the second end is defined as an insertion section. The insertion section is adapted to the inner hole of the above-mentioned sleeve 220. During installation, the insertion section is inserted into the above-mentioned sleeve 220, and a matching clamping part is installed at the above-mentioned second end. The matching clamping part is used to cooperate with the above-mentioned protrusion 310 to clamp the sleeve 220. In this way, the matching clamping part and the above-mentioned protrusion 310 constitute the above-mentioned locking assembly.

[0056] Specifically, the above-mentioned mating clamping portion includes a stud 320 and a second nut 330. The stud 320 is fixed to the above-mentioned second end of the above-mentioned straight rod body. The above-mentioned stud 320 is coaxially arranged with the above-mentioned straight rod body. The second nut 330 is screwed to the above-mentioned stud 320. The above-mentioned second nut 330 and the above-mentioned protrusion 310 are respectively arranged on both sides of the above-mentioned sleeve 220. When locking, the above-mentioned protrusion 310 and the above-mentioned second nut 330 are respectively tightly attached to the two ends of the above-mentioned sleeve 220. In this way, when the second nut 330 is tightened, the second nut 330 and the protrusion 310 clamp the above-mentioned sleeve 220, thereby locking the distance rod 300 in the sleeve 220. When the second nut 330 is unscrewed, the distance rod 300 can be removed from the sleeve 220.

[0057] Of course, a threaded hole can also be opened at the second end of the above-mentioned distance rod 300. In this case, a screw can be used instead of the above-mentioned second nut 330 and stud 320. Specifically, the screw is screwed into the threaded hole at the second end, and the nut of the nut and the above-mentioned protrusion 310 jointly clamp the sleeve 220.

[0058] An optional implementation of this embodiment is as follows: two distance rods 300 are configured, one with a length of 90 mm and the other with a length of 150 mm. Of course, more distance rods 300 may be configured, such as three, four, five, or more, each with a different length.

[0059] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope of the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
