Description

Technical Field

[0001] This utility model relates to the field of tapered sleeve detection technology, and in particular to a tool for measuring the tapered sleeve hole assembly of a pulley. Background Technology

[0002] Tapered bore pulleys are standard products and require a matching tapered sleeve for convenient use on drive shafts of different diameters. Each tapered sleeve has a set of commonly used center bore diameters, which are standard series products. The inner tapered bore of the pulley and the outer tapered surface of the tapered sleeve each have two half-threaded holes and one half-smooth hole, which, along with screws, connect the two together for installation and fixation on the drive shaft. To ensure smooth installation without compromising their respective accuracy, the dimensions and positions of the connecting holes must be accurate, with errors controlled within a certain range.

[0003] Without comprehensive inspection tools, inspectors use general-purpose measuring tools to measure, calculate, and convert data to determine whether the measurement is qualified or not. This process is cumbersome, time-consuming, and labor-intensive, and has a high probability of error. Therefore, this utility model proposes a tool for measuring the taper sleeve hole assembly of a pulley to overcome the shortcomings of the existing technology. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a tool for measuring the hole assembly of a pulley taper sleeve. By setting a positioning key on the top of the positioning mechanism that matches the keyway on the taper sleeve body, the taper sleeve body can be positioned and fixed in the center hole of the positioning template. By using a measuring camera set on the measuring platform that matches the positions of the first half-bright hole, the first half-threaded hole, and the second half-threaded hole, accurate measurement of the fit between the existing half-bright hole and the two half-threaded holes on the taper sleeve body and the first half-bright hole, the first half-threaded hole, and the second half-threaded hole can be achieved. The measuring camera has the advantage of high accuracy and can effectively reduce detection errors.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tool for measuring the hole assembly of a pulley taper sleeve includes a measuring frame, a positioning template, a support frame, and a measuring plate. The positioning template is located on the top of the measuring frame, and a first semi-finished hole, a first semi-threaded hole, and a second semi-threaded hole are located at the center hole of the positioning template. A positioning mechanism is provided on the measuring frame, and a positioning key that matches the keyway on the taper sleeve body is located on the top of the positioning mechanism. A support frame is located on the top of the positioning template, and a measuring plate is movably mounted on the support frame.

A measuring camera is located in the through groove, and a distance measuring sensor is located in the mounting groove at the bottom of the measuring plate.

[0007] A further improvement is that the positioning mechanism includes a support cylinder and a support circular plate. The measuring table is equipped with a support cylinder, and the output end of the support cylinder is equipped with a support circular plate. The support circular plate is concentrically arranged with the center hole of the positioning template, and the positioning key is located on the top of the support circular plate.

[0008] A further improvement is that the support frame includes a top plate and a ring plate, the ring plate is installed with the positioning template through a first connecting column, and the top plate is connected to the top of the ring plate through a second connecting column.

[0009] A further improvement is that the measuring platform is located inside the ring plate, and a movable cylinder is provided on the top plate, with the output end of the movable cylinder connected to the top of the measuring platform.

[0010] A further improvement is that the depth of the center hole of the positioning template is adapted to the height of the cone sleeve body, and the top of the support circular plate is flush with the bottom of the center hole of the positioning template.

[0011] A further improvement is that the surface of the supporting circular plate is provided with anti-slip texture.

The first semi-finished hole, the first semi-threaded hole, and the second semi-threaded hole on the positioning template are adapted to the existing semi-finished hole and two semi-threaded holes on the tapered sleeve body. By setting a positioning key on the top of the positioning mechanism that is adapted to the keyway on the tapered sleeve body, the tapered sleeve body can be positioned and fixed in the center hole of the positioning template by the positioning key. By setting a measuring camera on the measuring platform that is adapted to the positions of the first semi-finished hole, the first semi-threaded hole, and the second semi-threaded hole, the fitting degree between the existing semi-finished hole and the two semi-threaded holes on the tapered sleeve body and the first semi-finished hole, the first semi-threaded hole, and the second semi-threaded hole can be accurately measured.

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1-4 As shown in the figure, this embodiment proposes a tool for measuring the hole assembly of a pulley taper sleeve, including a measuring frame 1, a positioning template 2, a support frame 3, and a measuring plate 4. The measuring frame 1 is provided with a positioning template 2 on its top. The positioning template 2 has a first semi-finished hole 5, a first semi-threaded hole 6, and a second semi-threaded hole 7 at its center hole. The measuring frame 1 is provided with a positioning mechanism. The top of the positioning mechanism is provided with a positioning key 8 that matches the keyway on the taper sleeve body 14. The positioning template 2 is provided with a support frame 3 on its top. The measuring plate 4 is movably mounted on the support frame 3. The bottom of the measuring plate 4 is provided with a through groove that matches the positions of the first semi-finished hole 5, the first semi-threaded hole 6, and the second semi-threaded hole 7. A measuring camera 9 is provided in the through groove. The bottom of the measuring plate 4 is provided with a mounting groove, in which a distance measuring sensor 10 is provided.

[0021] When using the tool for measuring the taper sleeve hole assembly of this utility model, the taper sleeve body 14 is first placed into the center hole of the positioning template 2. During this process, the positioning key 8 on the top of the positioning mechanism is adapted to the keyway on the taper sleeve body 14, allowing the taper sleeve body 14 to complete standard positioning via the positioning key 8. Then, the alignment accuracy between the first semi-optical hole 5 and the semi-optical hole on the taper sleeve body 14 is measured by the measuring camera 9 on the measuring platform 4, and the alignment accuracy between the first semi-threaded hole 6 and the second semi-threaded hole and the two semi-threaded holes on the taper sleeve body 14 is measured. The distance sensor 10 is used to measure the distance between the top of the taper sleeve body 14 and the bottom of the measuring platform 4 to determine whether the height dimension of the taper sleeve body 14 meets the standard.

[0022] The positioning mechanism includes a support cylinder 11 and a support circular plate 12. The measuring stand 1 is equipped with the support cylinder 11, and the output end of the support cylinder 11 is equipped with the support circular plate 12. The support circular plate 12 is concentrically arranged with the center hole of the positioning template 2, and the positioning key 8 is located on the top of the support circular plate 12. The support circular plate 12 of the positioning mechanism of this utility model is used to support the conical sleeve body 14, and after the measurement of the conical sleeve body 14 is completed, it can push the conical sleeve body 14 out of the center hole of the positioning template 2, which facilitates quick disassembly of the conical sleeve body 14.

[0023] The support frame 3 includes a top plate 301 and a ring plate 302. The ring plate 302 is installed with the positioning template 2 via a first connecting column 303, and the top plate 301 is connected to the top of the ring plate 302 via a second connecting column 304. The measuring platform 4 is disposed inside the ring plate 302, and a moving cylinder 13 is provided on the top plate 301. The output end of the moving cylinder 13 is connected to the top of the measuring platform 4. This utility model, by setting the moving cylinder 13 to drive the measuring platform 4 to move, can realize the adjustment of the height of the measuring camera 9 to take pictures and measure, so as to meet the flexible use needs. When the distance sensor 10 measures the distance between the top of the cone sleeve body 14 and the bottom of the measuring platform 4, the moving cylinder 13 can be used to drive the measuring platform 4 to a lower position, so that the measuring platform 4 reaches a position where it can no longer move. The measurement data of the distance sensor 10 is used to determine whether the height dimension of the cone sleeve body 14 is qualified.

[0024] The depth of the center hole of the positioning template 2 is adapted to the height of the conical sleeve body 14, and the top of the supporting circular plate 12 is flush with the bottom of the center hole of the positioning template 2. This arrangement ensures that the size of the center hole is adapted to the size of the conical sleeve body 14.

[0025] The surface of the supporting circular plate 12 is provided with anti-slip texture, which can improve the positioning stability of the cone sleeve body 14.

[0026] This utility model comprises a measuring frame 1, a positioning template 2, a support frame 3, and a measuring plate 4. The first semi-finished hole 5, the first semi-threaded hole 6, and the second semi-threaded hole 7 on the positioning template 2 are adapted to the existing semi-finished hole and two semi-threaded holes on the tapered sleeve body 14. By setting a positioning key 8 on the top of the positioning mechanism that is adapted to the keyway on the tapered sleeve body 14, the tapered sleeve body 14 can be positioned and fixed in the center hole of the positioning template 2 by the positioning key 8. The measuring camera 9 set on the measuring plate 4 and adapted to the positions of the first semi-finished hole 5, the first semi-threaded hole 6, and the second semi-threaded hole 7 can accurately measure the fit between the existing semi-finished hole and two semi-threaded holes on the tapered sleeve body 14 and the first semi-finished hole 5, the first semi-threaded hole 6, and the second semi-threaded hole 7. The measuring camera 9 has the advantage of high accuracy and can effectively reduce the detection error.

[0027] This utility model uses a distance sensor 10 installed in the mounting groove at the bottom of the measuring platform 4 to movably connect the measuring platform 4 and the support frame 3 and drive it with a moving cylinder 13. After the measuring platform 4 is lowered, the distance sensor 10 measures the distance between the measuring platform 4 and the top of the cone sleeve body 14. This allows the tool of this utility model to not only achieve the accuracy of measuring the hole group, but also to measure the height of the cone sleeve body 14, which is highly flexible.
