Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of parts processing, in particular to a tool for processing slotting of tapered parts. Background Art
[0002] In actual production, parts will be processed into conical covers according to usage requirements. If the conical parts need to be further processed on the outer surface, they usually cannot be directly clamped using the fixtures on lathes, milling machines or four-axis lathes due to the taper on their surfaces. Therefore, the fixtures of existing processing equipment cannot meet the needs of conical parts processing.
[0003] Although there are currently different processing devices that can clamp the two ends of a conical part, for example, Chinese utility model patent application number 2232428462.X provides a conical part processing device that clamps a conical tube through a first stopper and a second stopper, and then facilitates grinding of the conical tube.
[0004] However, the existing processing tools for tapered parts cannot meet the requirements of opening U-shaped grooves on tapered parts. Figure 1 As shown, the U-shaped groove is opened on the side wall of the conical part, and the U-shaped groove is arranged along the axial direction of the conical part. There are multiple U-shaped grooves, and the multiple U-shaped grooves are arranged at equal intervals around the axis. The notch of the U-shaped groove is located at the port of the conical part, so that multiple movable blades are formed on the conical part, and a U-shaped groove is formed between two adjacent movable blades on the left and right.
[0005] When the conical parts are clamped by fixing at both ends, the processing accuracy and efficiency of the conical parts will be affected; at the same time, if the U-shaped groove is processed by only fixing at one end, the movable blades will vibrate, increasing the difficulty of processing; therefore, the existing processing tooling for conical parts cannot meet the actual processing needs. Utility Model Content
[0006] The utility model aims to provide a conical part slotting processing tool to solve the technical problem that the current conical part processing tool cannot meet the requirements of conical part U-shaped slot processing.
[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0008] A tool for processing slotting of a conical part, comprising an outer hoop cover sleeved on the outer side of the conical part and an inner top ring arranged on the inner side of the conical part, wherein the inner top ring is arranged coaxially with the conical part;
[0009] A clamping piece is arranged at one end of the outer hoop cover, and the other end of the outer hoop cover extends to the outside of the port of the conical part, and a processing limiting groove is opened between the corresponding two ends of the side wall of the outer hoop cover; a tightening piece is arranged on the inner top ring, and the tightening piece is used to tighten the inner wall of the conical part.
[0010] It is further defined that there are multiple inner top rings, and the multiple inner top rings are arranged at intervals along the axis of the outer hoop cover.
[0011] It is further defined that a first buffer pad is provided at one end of the tightening member, and the other end of the tightening member is detachably connected to the inner top ring.
[0012] It is further defined that the inner wall of the outer hoop cover is provided with a second buffer pad.
[0013] It is further defined that the length of the processing limit groove is greater than the length of the U-shaped groove on the tapered part, and the width of the processing limit groove is greater than the width of the U-shaped groove.
[0014] It is further defined that the number of the processing limit grooves is the same as the number of the U-shaped grooves, and the processing limit grooves and the U-shaped grooves are arranged in a one-to-one correspondence.
[0015] It is further defined that the number of the tightening members on the inner top ring is the same as the number of the U-shaped grooves, and the U-shaped groove is located between two adjacent tightening members on the inner top ring.
[0016] It is further defined that the tightening member is a bolt.
[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0018] 1. The utility model uses an outer hoop cover and an inner top ring to limit the conical part, and uses a clamping piece on the outer hoop cover to connect with a lathe, so as to achieve stable clamping of the conical part; at the same time, a processing limit groove is selected between the two ends of the side wall of the outer hoop cover, so as to facilitate the U-shaped groove processing of the internal conical part along the processing limit groove, and at the same time, the top tightening piece on the outer side of the processing limit groove is contacted with the inner wall of the conical part, and while reserving the U-shaped groove processing space, the movable blade is limited by the top tightening piece to avoid its vibration, further reducing the processing difficulty, improving the processing efficiency, and meeting the actual processing needs.
[0019] 2. The size of the limit groove processed by the utility model is larger than that of the U-shaped groove, which avoids damage to the outer hoop cover during processing and ensures its service life; at the same time, by arranging the first buffer pad and the second buffer pad, the surface of the conical part can be protected to avoid damage to the conical part and ensure the processing quality.

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model is further described in detail in combination with the accompanying drawings and embodiments. The specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model. Specific details such as specific system structures and technologies are proposed in order to more thoroughly understand the embodiments of the utility model. The described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. However, it should be clear to those skilled in the art that the utility model can also be implemented in other embodiments without these specific details. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection disclosed by the present utility model.
[0027] refer to Figure 1 A plurality of U-shaped grooves a are provided on the conical part A. Since the port of the U-shaped groove a is located at the port of the conical part A, the side wall of the conical part A is composed of a plurality of movable blades b. The plurality of movable blades b are arranged at intervals around the axis of the conical part A. Each movable blade b is located between two adjacent U-shaped grooves a. Therefore, when the conical part A is processed, its open end cannot be clamped and fixed. If only the closed end is clamped and fixed, when the U-shaped groove a is processed, the formed movable blades b and the movable blades b gradually formed during the processing will vibrate, affecting the processing, increasing the processing difficulty and reducing the processing accuracy. Therefore, the existing processing tooling cannot meet the use requirements.
[0028] Example 1
[0029] refer to Figure 2 and Figure 3 This embodiment provides a conical part grooving processing tool, including an outer hoop cover 1 and an inner top ring 2; wherein the inner top ring 2 is arranged inside the outer hoop cover 1, and a processing limit groove 4 is opened on the outer hoop cover 1.
[0030] When in use, the outer hoop cover 1 is sleeved on the outer side of the conical part A, so that the inner wall of the outer hoop cover 1 fits with the outer wall of the conical part A, and the conical part A is coaxially arranged with the outer hoop cover 1; then the inner top ring 2 is arranged inside the conical part A, and then the inner top ring 2 tightens the inner wall of the conical part A through the tightening piece 5, so that the conical part A is clamped between the outer hoop cover 1 and the tightening piece 5, thereby achieving stable clamping of the conical part A.
[0031] Specifically, a clamping member 3 is provided at one end of the outer hoop cover 1, and the clamping member 3 is used to connect with the fixture of the processing machine tool. For example, the processing machine tool is a four-axis lathe. During processing, the tool performs U-shaped groove a processing on the clamped conical part A along the processing limit groove 4 to ensure safe and reliable processing.
[0032] The other end of the outer hoop cover 1 is an open end, and the open end of the outer hoop cover 1 preferably extends to the outside of the open end of the conical part A, that is, during processing, the open end of the outer hoop cover 1 is higher than the open end of the conical part A. At this time, the processing limit groove 4 is located between the two ends of the outer hoop cover 1 to avoid the formation of movable blades on the outer wall of the outer hoop cover 1. At this time, it can ensure the stable limitation of the conical part A, and at the same time, the open end of the outer hoop cover 1 can be clamped according to needs to meet different processing needs.
[0033] The inner wall of the outer hoop cover 1 fits the outer wall of the conical part A. Preferably, the side wall thickness of the outer hoop cover 1 is uniform, so that the outer shape of the outer hoop cover 1 is the same as that of the conical part A, which is convenient for selecting the corresponding outer hoop cover 1 according to the shape of the conical part A.
[0034] Preferably, the length and width of the limit groove 4 processed on the outer hoop cover 1 are slightly larger than the length and width of the U-shaped groove a. For example, the length and width of the limit groove 4 are 2mm to 5mm larger than the length and width of the U-shaped groove a, so as to avoid contact and collision between the tool and the outer hoop cover 1 when processing the U-shaped groove a, thereby affecting the processing.
[0035] At the same time, a second buffer pad 7 can be optionally provided on the inner wall of the outer hoop cover 1 to protect the outer wall of the conical part A through the second buffer pad 7 to avoid damage to the outer wall of the conical part A, thereby ensuring reliable processing quality and meeting processing requirements; the second buffer pad 7 can be selected from rubber or a material with a lower hardness than the conical part.
[0036] refer to Figure 4 and Figure 5 , further illustrating, a plurality of tightening members 5 are provided on the inner top ring 2, and the plurality of tightening members 5 are arranged at intervals around the axis of the inner top ring 2, so that the tightening members 5 correspond one-to-one to the movable blades b on the conical part A, and are used to restrict the movable blades b between the outer hoop cover 1 and the ends of the tightening members 5 to prevent them from vibrating during processing; at this time, the number of the tightening members 5 on the inner top ring 2 is the same as the number of the movable blades b, and the tightening members 5 are preferably located in the middle position of the corresponding movable blades b.
[0037] The clamping member 5 can be selected as a block structure or a plate structure with the same width as or slightly smaller than the width of the movable blade b; the clamping member 5 can be selected so that one end contacts the inner wall of the conical part A, and the other end contacts the outer wall of the inner top ring 2.
[0038] In order to reduce the weight of the overall structure and improve the ease of installation, the tightening member 5 is preferably a bolt. During installation, the conical part A can be tightened through the inner top ring 2 by screwing the corresponding bolt. At the same time, the position of the tightening member 5 can be adjusted according to the thickness of the conical part A. The scope of application is wider and the actual processing needs can be further met.
[0039] Further preferably, a first buffer pad 6 is provided at one end of the tightening member 5 to prevent the tightening member 5 from damaging the inner wall of the conical part A when tightening the inner wall thereof, thereby ensuring processing quality; the other end of the tightening member 5 is threadedly connected to the inner top ring 2.
[0040] The number of the inner top rings 2 can be selected to be one, two or more. When the number of the inner top ring 2 is one, the inner top ring 2 is arranged at the port position of the conical part A.
[0041] When there are two inner top rings 2, the two inner top rings 2 are arranged relatively along the axis of the conical part A, one inner top ring 2 is arranged at the port position of the conical part A, and the other inner top ring 2 is arranged at the position close to the end of the U-shaped groove a.
[0042] When there are multiple inner top rings 2, taking three as an example, the three inner top rings 2 are arranged at intervals along the axis of the conical part A, one of the inner top rings 2 is arranged at the port position of the conical part A, and the remaining two inner top rings 2 are respectively tightened against the middle position and the bottom position of the movable blade b to ensure that the definition of the conical part A is stable and reliable.
[0043] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
