Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of precision part clamping tooling, and in particular relates to a precision part grinding clamping tooling. Background Art
[0002] As one of the important parts of various equipment such as aircraft engines, the normal operation of precision parts directly affects the performance and indicators of engines and other equipment. When grinding precision parts, they need to be clamped on the grinding bed for grinding the outer cylindrical surface. The clearance of precision parts is accurate to a few thousandths, so it is particularly important to take corresponding protective measures for the products during the grinding process.
[0003] The traditional method of grinding precision parts is to directly clamp the parts through the three-jaw chuck of the grinding machine. When clamped in this way, the force points of the parts should be the three points where the cylindrical surface of the part contacts the three-jaw chuck. However, since precision parts are often not regular cylindrical parts, the force points of the parts cannot reach three points, making it difficult to clamp the parts stably. When grinding at high speed, precision parts are prone to fall off and be damaged, resulting in the scrapping of precision parts. At the same time, the fallen products are also prone to injuring operators. Utility Model Content
[0004] The purpose of the utility model is to solve the technical problem that the existing technology uses a three-jaw chuck of a grinding machine to clamp precision parts, which leads to unstable clamping, making the precision parts easy to be scrapped and easily injuring operators, and to provide a precision part grinding clamping tool. The overall structural design of the utility model is simple and lightweight, abandoning the traditional method of directly clamping precision parts on a traditional grinding machine, which is easy to cause product damage. It is simple to operate, ensures product quality and safety, and improves production efficiency, and has great practical application value.
[0005] To achieve the above purpose, the technical solution provided by the utility model is:
[0006] A precision part grinding clamping tool, which is special in that it includes a clamping rod and a fixing sleeve;
[0007] The clamping rod is cylindrical, and its first end is used to be clamped by the three-jaw chuck of the grinding machine, and its second end is processed with an external thread and has a limiting hole inside, which is used to cooperate with the precision parts to be ground;
[0008] The fixing sleeve is cylindrical, and the first end of the fixing sleeve is processed with an internal thread for threaded connection with the external thread at the second end of the clamping rod. The second end of the fixing sleeve is provided with a matching hole for matching with the precision mating part to fix the precision mating part together with the limiting hole.
[0009] Furthermore, the limiting hole of the clamping rod is a conical hole, and the matching hole of the fixing sleeve is also a conical hole.
[0010] Further, the diameter of the first end of the clamping rod is smaller than the diameter of the second end.
[0011] Further, the diameter of the first end portion of the fixing sleeve is greater than the diameter of the second end portion.
[0012] Furthermore, the clamping rod and the fixing sleeve are both made of hard aluminum alloy.
[0013] The advantages of the utility model are:
[0014] 1. The precision mating part grinding clamping tool of the utility model includes a clamping rod and a fixing sleeve connected by threads. The clamping rod is used to be clamped by the three-jaw chuck of the grinding machine. The limiting hole on the clamping rod and the matching hole on the fixing sleeve jointly fix the precision mating part to be ground. Therefore, when grinding precision mating parts that are not regular cylindrical, the parts are clamped by the three-jaw chuck through the cylindrical clamping rod of the utility model, avoiding the direct clamping of the precision mating parts by the three-jaw chuck. While protecting the precision mating parts, stable and reliable clamping of the precision mating parts is achieved through three clamping positions; in addition, compared with the prior art in which the parts are subjected to no more than three force points when the precision mating parts are ground and clamped, the utility model uses the limiting hole on the clamping rod and the matching hole on the fixing sleeve to wrap the outer peripheral surface of the precision mating parts, thereby supporting the entire circumference of the parts, increasing the rigidity of the parts during processing, and improving the grinding accuracy.
[0015] 2. The limiting hole of the clamping rod and the matching hole of the fixing sleeve are both set as conical holes, which can clamp the conical section of the precision mating parts.
[0016] 3. The clamping rod and the fixed sleeve are designed with one end larger than the other, which is convenient for operators to grasp and can improve the grinding efficiency of precision parts. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be described in detail below with reference to the accompanying drawings by means of exemplary embodiments of the present invention. It should be noted that the following detailed description of the present invention is only for the purpose of illustration, and is not intended to limit the present invention.
[0024] The utility model provides a precision part grinding clamping tool, which is used for clamping the precision part when grinding the precision part, avoiding direct clamping of the precision part by a three-jaw chuck of a grinding bed, and realizing stable and reliable clamping of the part.
[0025] Reference Figures 1 to 3 The precision mating parts grinding clamping tooling as an exemplary embodiment of the utility model comprises a clamping rod 1 and a fixing sleeve 2. The clamping rod 1 is used to be clamped by a three-jaw chuck of a grinding machine. The clamping rod 1 and the fixing sleeve 2 together fix the precision mating parts to be ground.
[0026] Combined with reference Figure 1 and Figure 2 The clamping rod 1 is made of hard aluminum alloy, is cylindrical, and has a first end 11 and a second end 12. The first end 11 of the clamping rod 1 is used to be clamped by the three-jaw chuck of the grinding machine, and the second end 12 of the clamping rod 1 is processed with an external thread (not shown) and is provided with a limiting hole 121 inside, which is used to cooperate with the precision mating part to be ground. It should be understood that the shape of the limiting hole 121 can be designed according to the structure of the precision mating part to be processed and the structure of the part to be clamped, and can be designed to be cylindrical or conical.
[0027] See also Figure 1 and Figure 3The fixing sleeve 2 is made of hard aluminum alloy, is cylindrical, and has a first end 21 and a second end 22. The first end 21 of the fixing sleeve 2 is processed with an internal thread (not shown), which is used to be threadedly connected with the external thread at the second end 12 of the clamping rod 1. The stability of the clamping is ensured by the self-locking property of the thread. A matching hole 221 is provided in the second end 22 of the fixing sleeve 2, which is used to match with the precision mating part to fix the precision mating part together with the limiting hole 121. That is to say, the limiting hole 121 and the matching hole 221 are coaxial, and the precision mating part is clamped at two positions, one at the limiting hole 121 on the second end 12 of the clamping rod 1, and the other at the matching hole 221 on the second end 22 of the fixing sleeve 2. The shapes of the limiting hole 121 and the matching hole 221 can be designed according to the clamping position of the precision mating part. For example, when the cylindrical section of the precision mating part needs to be clamped, both holes are designed to be cylindrical. At this time, according to the requirements, the inner diameter of the second end 12 of the fixing sleeve 2 can be smaller than the inner diameter of the first end 21, instead of Figure 3 When the conical section of the precision mating part needs to be clamped, the limiting hole 121 and the matching hole 221 are both set as conical holes, and the sizes of the two are adapted to the shape and size of the precision mating part. In this way, when the precision mating part is clamped and ground by the tooling of the utility model, the limiting hole and the matching hole circumferentially wrap the outer peripheral surface of the precision mating part, forming support for the entire circumference of the precision mating part, which can improve the processing rigidity of the part.
[0028] The grinding clamping tool of the utility model has strong portability, can stably clamp products for processing, is not limited to a specific workplace, and greatly improves the grinding efficiency. At the same time, the grinding tool has strong reliability, reduces the influence of human factors, fundamentally solves the problem of product damage or scrapping caused by human operation, and saves production costs.
[0029] In order to facilitate the operator to grasp and improve the grinding efficiency of precision parts, in some embodiments of the present invention, the diameter of the first end 11 of the clamping rod 1 is smaller than the diameter of the second end 12. Similarly, the diameter of the first end 21 of the fixing sleeve 2 can be larger than the diameter of the second end 22.
[0030] As described above, the precision mating part grinding clamping tool of the utility model includes a clamping rod and a fixing sleeve connected by threads, the clamping rod is used to be clamped by the three-jaw chuck of the grinding machine, and the limiting hole on the clamping rod and the matching hole on the fixing sleeve jointly fix the precision mating part to be ground. Therefore, when grinding precision mating parts that are not regular cylindrical, the parts are clamped by the three-jaw chuck through the cylindrical clamping rod of the utility model, avoiding the direct clamping of the precision mating parts by the three-jaw chuck, while protecting the precision mating parts, stable and reliable clamping of the precision mating parts is achieved through three clamping positions; in addition, compared with the prior art in which the parts are subjected to no more than three force points when the precision mating parts are ground and clamped, the utility model uses the limiting holes on the clamping rod and the matching holes on the fixing sleeve to wrap the outer peripheral surface of the precision mating parts, thereby supporting the entire circumference of the parts, increasing the rigidity of the parts during processing, and improving the grinding accuracy.
[0031] Finally, it should be noted that the features mentioned and / or shown in the above description of the exemplary embodiments of the utility model can be combined in the same or similar manner into one or more other embodiments, combined with the features in other embodiments or replace the corresponding features in other implementations. The technical solutions obtained by these combinations or replacements should also be deemed to be included in the protection scope of the utility model.
