Description

Technical Field

[0001] This utility model relates to the field of mechanical assembly technology, and in particular to a gear-shaping tool. Background Technology

[0002] The core of gear machining is the tooth profile machining of the gear ring. The gear shaping process for gear parts is limited by factors such as part size and machine tool travel, and auxiliary tooling is required for smooth machining. However, auxiliary tooling is not universal; different types of gear parts require tooling of different sizes for machining, meaning that tooling must be changed when changing parts. Moreover, changing tooling requires cleaning the worktable surface, clamping, and dial indicator installation, with the clamping and dial indicator installation process taking about ten minutes, resulting in low machining efficiency.

[0003] Therefore, how to provide a gear-shaping tool that can improve processing efficiency and has good versatility is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention provides a gear-shaping tool to solve the problems of poor versatility and low processing efficiency of existing gear-shaping tooling for toothed parts.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A gear-shaping fixture includes a mounting base, a plurality of first fixing components, and a plurality of second fixing components. The mounting base has a first mounting portion and a second mounting portion at its two opposite ends. The first mounting portion is fitted onto a worktable, and the second mounting portion is used to place a workpiece to be processed. The inner wall of the mounting base near the workpiece is stepped. Both the first fixing components and the second fixing components are disposed on the worktable, and the first fixing components and the second fixing components apply a first force and a second force to the mounting base and the workpiece to be processed, respectively. Both the first force and the second force have at least a component in a direction perpendicular to the plane of the worktable.

[0007] Preferably, the first fixing component includes a first force-applying member and a first fixing member. The first force-applying member is arranged parallel to the worktable and has a first mounting hole. One end of the first fixing member can pass through the first mounting hole and be fixed to the worktable, and the other end can abut against the first force-applying member.

[0008] Preferably, the side wall of the mounting base is provided with a plurality of grooves, and the first force-applying member can extend into the grooves. The mounting base is fixed to the worktable by the cooperation of the first force-applying member and the first fixing member.

[0009] Preferably, the second fixing component includes a second force-applying member and a second fixing member. The second force-applying member is arranged parallel to the worktable and has a second mounting hole. One end of the second fixing member can pass through the second mounting hole and be fixed to the worktable, and the other end can abut against the second force-applying member.

[0010] Preferably, one end of the second force-applying member extends toward the axial direction of the mounting base, and the part to be processed is fixed to the mounting base by the cooperation of the second force-applying member and the second fixing member.

[0011] Preferably, both the first mounting hole and the second mounting hole are strip-shaped holes.

[0012] Preferably, both the first fixing member and the second fixing member include a screw and a nut. One end of the screw passes through the first mounting hole / second mounting hole and is fixed to the worktable, while the other end is abutted against the first force-applying member / second force-applying member by the nut.

[0015] The mounting base of this invention has a stepped inner wall at the end facing the workpiece, which can be applied to different toothed parts and has good versatility. At the same time, the mounting base is fixed to the worktable by the first fixing component. Based on this, the mounting base can be fixed to the worktable throughout the entire processing without the need for replacement, and the process of repeatedly using dial gauges when changing parts of different sizes is avoided. In addition, since the workpiece is fixed to the mounting base by the second fixing component, when it is necessary to change the workpiece, it can be done simply by adjusting the second fixing component, which effectively improves work efficiency.

[0020] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] like Figure 1As shown, this utility model provides a gear-shaping fixture, including a mounting base 200, a plurality of first fixing components 400, and a plurality of second fixing components 500; the mounting base 200 has a first mounting portion and a second mounting portion at its two opposite ends, the first mounting portion is fitted onto a worktable 100, and the second mounting portion is used to place a workpiece 300 to be processed, and the inner wall of the mounting base 200 near the workpiece 300 is stepped; wherein, the first fixing components 400 and the second fixing components 500 are both disposed on the worktable 100, and the first fixing components 400 and the second fixing components 500 respectively apply a first force and a second force to the mounting base 200 and the workpiece 300 to be processed, the first force and the second force both having a component force in at least a direction perpendicular to the plane of the worktable.

[0025] Understandably, the inner wall of the mounting base 200 facing the workpiece 300 of this utility model is set in a stepped shape, which can be applied to different toothed parts to be processed, and has good versatility. At the same time, the mounting base 200 is fixed to the worktable 100 by the first fixing component 400. Based on this, the mounting base 200 can always be fixed to the worktable 100 without disassembly or replacement during the entire processing, and avoids the process of repeatedly using dial gauges when changing parts of different sizes, thus improving work efficiency.

[0026] Since the part to be processed 300 is fixed to the mounting base 200 by the second fixing component 500, when the part to be processed 300 needs to be replaced, it can be achieved simply by adjusting the second fixing component 500. In addition, when the tooling is made, the height of the base can be reduced, and only the actual size of the part to be processed 300 needs to be made, thereby reducing the tooling manufacturing cost.

[0027] Furthermore, in this invention, it is only necessary to ensure that both the first and second forces have a component force in at least one direction perpendicular to the plane of the worktable 100. This can be achieved through clamping or magnetic adsorption, without specific limitations, as long as the mounting base 200 can be fixed to the worktable 100 and the workpiece 300 can be fixed to the mounting base 200. It should also be noted that having a component force in at least one direction is not limited to clamping only in the vertical direction; the clamping surface can also be set as an inclined plane, so that the mounting base is subjected to force in both the vertical and horizontal directions, improving stability.

[0028] In some embodiments of this utility model, the first fixing component 400 includes a first force-applying component 410 and a first fixing component 420. The first force-applying component 410 is arranged parallel to the workbench 100 and is provided with a first mounting hole. One end of the first fixing component 420 can pass through the first mounting hole and be fixed to the workbench 100, and the other end can abut against the first force-applying component 410.

[0029] Optionally, the side wall of the mounting base 200 is provided with multiple grooves, and the first force-applying member 410 can extend into the grooves. The mounting base 200 is fixed to the worktable 100 by the cooperation of the first force-applying member 410 and the first fixing member 420.

[0030] Understandably, multiple first fixing components 400 are provided, such as two, three, or more, evenly distributed on the outside of the mounting base 200 to securely fix the mounting base 200 to the worktable 100. Specifically, the first force-applying member 410 can be elongated, with one end wedge-shaped and extending into the groove of the mounting base 200, and the other end having a first mounting hole. After the first fixing member 420 passes through the first mounting hole, both ends are fixed to the worktable 100 and the top of the first force-applying member 410, respectively, to achieve the fixation of the mounting base 200. The structure is simple and the installation and disassembly process is easy to operate.

[0031] In some embodiments of this utility model, the second fixing component 500 includes a second force-applying member 510 and a second fixing member 520. The second force-applying member 510 is arranged parallel to the workbench 100 and is provided with a second mounting hole. One end of the second fixing member 520 can pass through the second mounting hole and be fixed to the workbench 100, and the other end can abut against the second force-applying member 510.

[0032] Optionally, one end of the second force-applying member 510 extends toward the axial direction of the mounting base 200, and the workpiece 300 to be processed is fixed to the mounting base 200 by the cooperation of the second force-applying member 510 and the second fixing member 520.

[0033] Understandably, multiple second fixing components 500 are provided, such as two, three, or more, evenly distributed on the outer side of the workpiece 300 to securely fix the workpiece 300 to the mounting base 200. Specifically, the second force-applying component 510 can be elongated, with one end wedge-shaped and extending to one side of the workpiece 300. If the outer wall of the workpiece 300 has a hole or groove, it can extend into the hole or groove. If the outer wall of the workpiece 300 is a smooth surface, the wedge-shaped end of the second force-applying component 510 is placed on the top surface of the workpiece 300 to provide a downward force. The other end of the second force-applying component 510 has a second mounting hole. After the second fixing component 520 passes through the second mounting hole, both ends are fixed to the worktable 100 and the top of the second force-applying component 510, respectively, to achieve the fixation of the workpiece 300. The structure is simple and the installation and disassembly process is easy to operate.

[0034] In some embodiments of this utility model, the first fixing member 420 and the second fixing member 520 both include a screw and a nut. One end of the screw passes through the first mounting hole / second mounting hole and is fixed to the workbench 100, and the other end is abutted against the first force-applying member 410 / second force-applying member 510 by the nut.

[0035] This invention enables the installation of the mounting base 200 and the workpiece 300 by using common screws and nuts, eliminating the need for manufacturing complex parts. It features a simple structure, easy operation, and low cost.

[0036] In some embodiments of this utility model, the mounting base 200 has a hollow structure, and at least one operating hole 210 is provided at one end of the mounting base 200 facing the workbench 100. When installing or removing the mounting base 200, it is more convenient and easier to operate by means of the operating hole 210.

[0037] The working process of this utility model gear-shaping tool is as follows:

[0038] Before processing, clean the machine tool worktable 100 and mark the surface of the worktable 100. Connect the mounting base 200 to the worktable 100, use the first fixing component 400 to fix the mounting base 200 to the worktable 100, and mark the end face of the mounting base 200. Then, change the part to be processed 300 as needed and fix the part to be processed 300 to the mounting base 200 to meet the gear hobbing processing of parts of different sizes.

[0039] In summary, the gear hobbing fixture provided by this utility model has good versatility and can be applied to different parts to be processed, avoiding the process of repeatedly using dial gauges when changing parts of different sizes, effectively improving work efficiency and reducing processing costs.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
