Description

Technical Field

[0001] The utility model belongs to the technical field of roller detection, and in particular relates to a roller tapered hole measuring device. Background Art

[0002] The most commonly used processing method for processing large rollers is lathe processing. There are two common clamping methods when processing rollers on a lathe. The first is chuck clamping: this clamping method will cause wear on the outer diameter surface of the roller, and because it is not a one-time processing, the axis cannot be guaranteed to be the same as the first clamping during the second clamping, and the precision of the processed roller is difficult to meet the requirements of fine processing. The second is the top hole (taper hole) clamping: the top holes are processed in the recesses at both ends of the roller during rough turning, and the corresponding clamping tooling can be used to clamp at the top holes during fine turning. The entire raceway surface can be processed by clamping once, which can better ensure the precision requirements of fine processing compared to chuck clamping, and will not affect the raceway surface due to processing reasons (such as wear, bumps, and scratches). Therefore, the top hole clamping processing method is selected for fine processing.

[0003] Since the top hole needs to be processed and formed in the rough turning process, the size of the formed top hole needs to be measured after the top hole is processed and formed to ensure the consistency of the top holes in the batch of rollers, and then meet the dimensional accuracy and consistency of the subsequent roller processing. However, there is no device in the prior art that can quickly detect the size of the top hole, or the detection device in the prior art has the problems of complex operation and low efficiency. Therefore, the inventor proposes a measuring device for roller tapered holes to solve the above problems. Utility Model Content

When detecting the tapered hole, the fitting surface of the positioning plate can be brought into contact with the end face of the roller, and the measuring head of the measuring meter can be placed in the tapered hole. Whether the roller tapered hole is qualified can be detected by reading the value of the measuring meter. The utility model has the advantages of a wide range of applications, easy operation and low cost.

[0005] The technical solution adopted by the utility model is: a roller tapered hole measuring device, comprising a measuring table and a positioning plate connected to the measuring table, the positioning plate is a disc-shaped structure, a mounting hole matching the shaft sleeve of the measuring table is opened at the center of the positioning plate, the shaft sleeve of the measuring table is installed at the mounting hole and the measuring table and the positioning plate are fixed by screws, the moving axis of the measuring rod of the measuring table coincides with the center line of the positioning plate, and the measuring head of the measuring table passes through the mounting hole of the positioning plate and extends outward to the other side of the positioning plate.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1-4As shown, a roller tapered hole measuring device includes a measuring gauge 1 and a positioning plate 2 connected to the measuring gauge 1, wherein the measuring gauge 1 is a dial gauge or a micrometer, and the measuring head 103 of the measuring gauge 1 is spherical in shape, and the steel ball can be fixed to the end position of the measuring rod 102 by welding or the like. Compared with the V-shaped measuring head 103 structure of the traditional dial gauge or micrometer, the spherical measuring head 103 can better contact with the inner wall of the tapered hole 301, and there is no problem of sticking, etc., and it can be applied to the measurement of tapered holes 301 of different sizes, and has strong versatility.

[0019] The positioning disk 2 is a disk-shaped structure, and a mounting hole 203 matching the sleeve 101 of the measuring table 1 is opened in the center of the positioning disk 2, wherein the mounting hole 203 and the sleeve 101 of the measuring table 1 are clearance-fitted to ensure that the center line of the sleeve 101 coincides with the center line of the positioning disk 2.

[0020] The shaft sleeve 101 of the measuring meter 1 is installed at the mounting hole 203 and the measuring meter 1 and the positioning plate 2 are fixed by screws. Specifically, a step portion 202 protruding upward is provided at the center of the positioning plate 2, the mounting hole 203 is opened at the center position of the step portion 202, and a plurality of threaded holes 204 connected to the mounting hole 203 are opened in the circumferential direction of the step portion 202. Screws can be inserted into the threaded holes 204, and the measuring meter 1 and the positioning plate 2 are connected and fixed by screws.

[0021] The moving axis of the measuring rod 102 of the measuring scale 1 coincides with the center line of the positioning disk 2, and the measuring head 103 of the measuring scale 1 passes through the mounting hole 203 of the positioning disk 2 and extends outward to the other side of the positioning disk 2. This arrangement allows the measuring head 103 to extend to the external position of the positioning disk 2, leaving sufficient space for subsequent measurement of the size of the tapered hole 301.

[0022] The positioning plate 2 has a fitting surface 201 in contact with the end surface of the roller 3. The fitting surface 201 is perpendicular to the movement direction of the measuring head 103 of the measuring table 1. The fitting surface 201 can be used as a reference surface when measuring the tapered hole 301, which is convenient for positioning the roller 3.

[0023] When this roller tapered hole measuring device is in use, one end of the roller 3 having the tapered hole 301 is placed close to the fitting surface 201 of the positioning plate 2, and the measuring head 103 of the measuring gauge 1 is placed in the tapered hole 301. When the end of the roller 3 contacts the fitting surface 201, the measuring rod 102 of the measuring gauge 1 is compressed back, so that the pointer on the measuring gauge 1 rotates. The operator can judge whether the tapered hole 301 is processed in place by reading the value on the measuring gauge 1.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
