Description

Technical Field

[0001] This utility model relates to the field of double-tooth technology, specifically a tooling for machining double-tooth joints. Background Technology

[0002] A double gear is a mechanical transmission device composed of two gears. It is mainly used to change the transmission ratio, improve transmission efficiency and stability. By adjusting the number of teeth and the module of the gears, a double gear can achieve different transmission ratio changes, thereby adapting to different working environments and conditions.

[0003] Double gears require a gear at each end for tooth alignment during use to ensure synchronized operation of mating parts during assembly. Current processing methods involve machining the large gear in a batch, clamping it with a chuck, and then machining the small gear. During small gear machining, the large gear needs to be visually inspected, and misalignment is frequent due to varying skill levels among personnel. Finished products also require sorting to select qualified products for customer assembly and disposal of defective ones. This method results in a high scrap rate and significant losses. Utility Model Content

[0004] The purpose of this invention is to provide a tooling for machining double-tooth joints to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling fixture for machining double-tooth teeth, comprising a tooling disc, a mounting ring mounted on the outer surface of the tooling disc, and three positioning components arranged in a ring on the outer surface of the tooling disc, the positioning components being used to position the double-tooth teeth, a circular groove being formed on the top outer surface of the tooling disc, a fixed shaft being connected to the bottom inner wall of the circular groove via a bearing, and a plug-in component being mounted on the top outer surface of the fixed shaft, the plug-in component being plugged into a tooling column via a plug-in end, the tooling column being used to support the double-tooth teeth, and a fixing component being provided inside the circular groove, the fixing component being used to fix the tooling column plug-in component.

[0006] Furthermore, the positioning component includes a mounting block, a positioning block, and a C-shaped limiting plate. The mounting block is fixed on the tooling plate, and a cylinder is mounted on the outer surface of the mounting block. A connecting plate is mounted on one end of the piston rod of the cylinder, and a rotating shaft is rotatably connected to the top of the outer surface of the connecting plate. A threaded head is mounted on one end of the rotating shaft.

[0007] Furthermore, the C-shaped limiting plate is fixed to the top outer surface of the mounting ring, and limiting grooves are provided on both inner walls of the C-shaped limiting plate, and the C-shaped limiting plate is used to limit the positioning block.

[0008] Furthermore, limit blocks are installed on both sides of the positioning block, and the limit blocks and the limit grooves form a sliding fit. One end of the positioning block is provided with a threaded groove, which is screwed to the threaded head.

[0009] Furthermore, the plug-in assembly includes a metal disk, which is fixedly connected to a fixed shaft, and a rectangular plug is mounted on the top surface of the metal disk.

[0010] Furthermore, the bottom surface of the tooling column is provided with a rectangular groove that matches the rectangular insert, and the surface of the tooling column is provided with four arc-shaped grooves distributed in a ring, with anti-slip pads installed inside the arc-shaped grooves.

[0011] Furthermore, the fixing component includes a ring electromagnet, on which four ring-shaped supports are mounted on the bottom outer surface. The supports are fixedly connected to the inner wall of the bottom of the circular groove. The ring electromagnet is used to attract the metal disk.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] A double-tooth machining fixture uses three positioning components to position the large tooth of the double-tooth assembly. Each positioning component uses a cylinder to drive a positioning block to position the large tooth. One end of the positioning block is inserted between the two gears of the large tooth, eliminating the need for manual operation and improving positioning efficiency. The fixture column can also rotate, and after rotation, it uses a ring electromagnet to attract and hold the metal disc of the insertion component, thus positioning the fixture column and meeting different machining requirements.

[0014] Meanwhile, the shape of the positioning block of the positioning component can be changed according to the requirements, and it can be adapted to the positioning of the large teeth of the double teeth of different specifications. Then the tooling column is inserted into the insertion component, and it can also be replaced later, making the entire tooling more flexible to meet different processing needs.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This invention significantly improves processing accuracy and efficiency. Through its automated positioning and flexible adjustment design, it can meet diverse processing needs, not only improving positioning efficiency but also reducing scrap rate and production costs. This makes the processing of double-tooth gears more efficient, accurate, and sustainable. In traditional double-tooth gear processing, the reliance on manual visual inspection for tooth alignment leads to inaccurate positioning and a high scrap rate. This is mainly due to differences in personnel skill levels, making it difficult to guarantee the accuracy of tooth alignment each time. At the same time, manual operation reduces processing efficiency and increases production costs. After introducing the double-tooth gear alignment fixture of this invention, the cylinders of the three positioning components drive the positioning block to automatically engage between the two gears of the large tooth, achieving precise positioning of the double-tooth gears. This automated positioning method not only improves positioning efficiency but also significantly reduces positioning errors caused by human factors.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a double-tooth machining tooling, including a tooling disc 1, a mounting ring 2 installed on the outer surface of the tooling disc 1, and three positioning components 3 arranged in a ring on the outer surface of the tooling disc 1. The positioning components 3 are used to position the double teeth. A circular groove 6 is opened on the top outer surface of the tooling disc 1. A fixed shaft 7 is connected to the bottom inner wall of the circular groove 6 through a bearing. An insertion component is installed on the top outer surface of the fixed shaft 7. A tooling column 4 is inserted into the insertion end of the insertion component. The tooling column 4 is used to support the double teeth. A fixing component is provided inside the circular groove 6, and the fixing component is used to fix the tooling column 4 insertion component.

[0023] It should be noted that the insertion end is a rectangular insertion block 9, and the tooling column 4 is made of metal, but its outer surface is coated with an insulating coating to make it non-magnetic. The double gear is fitted onto the tooling column 4, and then the three positioning components 3 can position the large tooth of the double gear. After the fixing components are released, the tooling column 4 can rotate to drive the double gear to adjust the angle and cooperate with the processing equipment for processing. Once the first double gear passes the inspection and is confirmed to be qualified, it can be confirmed that the two key processing data of the corresponding processing tool, the processing angle and the processing force, are correct. On this basis, the processing tasks of the entire batch of gears can be completed continuously and efficiently, and each product can meet the qualified standard.

[0024] The positioning component 3 includes a mounting block 31, a positioning block 36, and a C-shaped limiting plate 37. The mounting block 31 is fixed on the tooling plate 1. A cylinder 32 is mounted on the outer surface of the mounting block 31. A connecting plate 33 is mounted on one end of the piston rod of the cylinder 32. A rotating shaft 34 is rotatably connected to the top of the outer surface of the connecting plate 33, and a threaded head 35 is mounted on one end of the rotating shaft 34.

[0025] It should be noted that the positioning block 36 is located below the mounting ring 2 and connected to the outer surface of the tooling tray 1, and the connecting plate 33 is a rectangular strip.

[0026] C-shaped limiting plate 37 is fixed on the top outer surface of the mounting ring 2. Limiting grooves are provided on both inner walls of the C-shaped limiting plate 37, and the C-shaped limiting plate 37 is used to limit the positioning block 36.

[0027] It should be noted that the C-shaped limiting plate 37 is fixed to the mounting ring 2 by bolts and can be disassembled and replaced later. The C-shaped limiting plate 37 is used to enhance the stability of the positioning block 36.

[0028] Limiting blocks are installed on both sides of the positioning block 36. The limiting blocks and the limiting groove form a sliding fit. One end of the positioning block 36 is provided with a threaded groove, which is screwed to the threaded head 35.

[0029] It should be noted that the end of the positioning block 36 that contacts the large tooth should be pointed and have a certain curvature, so as to facilitate locking into the large tooth and avoid wear.

[0030] The plug-in assembly includes a metal disk 8, which is fixedly connected to a fixed shaft 7, and a rectangular plug 9 is mounted on the top surface of the metal disk 8.

[0031] It should be noted that the metal disc 8 is located inside the circular groove 6 and forms a rotational fit with the circular groove 6. The rectangular insert 9 is also made of metal.

[0032] The bottom surface of the tooling column 4 is provided with a rectangular groove that matches the rectangular insert 9, and the surface of the tooling column 4 is provided with four arc-shaped grooves distributed in a ring, with anti-slip pads 5 installed inside the arc-shaped grooves.

[0033] It should be noted that the curvature of the outer surface of the anti-slip pad 5 is matched with the outer curvature of the tooling column 4, and the stability after the double tooth sleeve is installed is increased.

[0034] The fixing component includes a ring electromagnet 10, and four ring-shaped support pillars are mounted on the bottom outer surface of the ring electromagnet 10. The support pillars are fixedly connected to the inner wall of the bottom of the circular groove 6. The ring electromagnet 10 is used to attract the metal disk 8.

[0035] It should be noted that after the annular electromagnet 10 is running, it attracts the metal disk 8, thereby giving the metal disk 8 and the rectangular insert 9 magnetic attraction, increasing the stability of the tooling column 4.

[0036] Working principle: The double gear is mounted on the tooling column 4. Then, the cylinders 32 of the three positioning components 3 drive the corresponding positioning blocks 36 to extend from the C-shaped limit plate 37, which can position the large tooth of the double gear, preventing the double gear from rotating, so that the small tooth can be processed. After the annular electromagnet 10 stops running, the tooling column 4 can rotate, thereby driving the double gear to rotate and adjust the angle to cooperate with the processing equipment for processing. Once the first double gear passes the inspection and is confirmed to be qualified, ensuring that one tooth of the large and small teeth are on the same line, it can be accurately indicated that the two key processing data of the corresponding processing tool's processing angle and processing force are correct. On this basis, the processing task of the entire batch of gears can be completed continuously and efficiently, and each product can meet the qualification standard.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
