Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a tooling for inserting inverted bevel gears. Background Technology

[0002] The inverted bevel gear has an inner hole consisting of three involute teeth: a straight tooth in the middle and bevel teeth on both sides. The three teeth must overlap without any deviation. Therefore, during the machining of the three teeth, they are first machined in one go. The two inverted bevel teeth need to be machined with a special tooling and fixed on the worktable of the gear shaper to ensure that the two inverted bevel teeth at both ends and the middle straight tooth are on the same line and do not deviate.

[0003] The existing processing method involves manually adjusting the clamping mechanism to hold the product. First, the three-section teeth are processed in one go. Then, one end is clamped to process the two ends of the reverse conical teeth. When processing the reverse conical teeth, the worktable needs to be slowly moved to the processed tooth groove for processing. This method is prone to tool collision, is greatly affected by human factors, is prone to misalignment, has poor consistency, has very low processing efficiency, and makes it difficult to guarantee product quality requirements. Utility Model Content

[0004] The purpose of this invention is to provide a tooling for inserting inverted bevel gears 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 for inserting inverted bevel gears, comprising a chuck and an annular base plate. The chuck is located inside the annular base plate, and three mounting brackets arranged in a ring are installed on the top outer surface of the annular base plate. The mounting brackets are fixedly connected to the chuck by bolts. The chuck is used to place products, and three positioning holes are provided on the bottom inner wall of the chuck. Positioning components are installed on one side of the three mounting brackets, and the positioning ends of the positioning components are located inside the positioning holes. The positioning components are used to position the products. An annular top cover is provided on the outer surface of the chuck, and four rectangular pressing components are installed on the top outer surface of the annular base plate. The pressing components are used to press the annular top cover.

[0006] Furthermore, the bottom surface of the chuck is equipped with three ring-shaped support pillars, and the bottom surface of the chuck has a circular opening.

[0007] Furthermore, all three positioning components include a first cylinder, which is fixed to the mounting bracket. An L-shaped plate is fixed to one end of the piston rod of the first cylinder, and a positioning post is installed on the top surface of the L-shaped plate.

[0008] Furthermore, the positioning post and the interior of the positioning port form a sliding fit, and the L-shaped plate and the bottom outer surface of the chuck form a sliding fit.

[0009] Furthermore, each of the four pressing components includes a fixed cover, which is fixed to the top outer surface of the annular base plate. A motor is installed inside the fixed cover, and a turntable is installed through the output end of the motor through the fixed cover. A second cylinder is installed on the top outer surface of the turntable, and a pressing plate is installed at the top of the piston rod of the second cylinder.

[0010] Furthermore, an anti-slip pad is installed on the bottom surface of the lower pressure plate, and the anti-slip pad contacts the top surface of the annular top cover, forming a rotational engagement between the turntable and the top surface of the fixed cover.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] A type of inverted bevel gear tooling allows the product to be processed to be placed in a chuck. Three positioning components engage with the product's internal tooth pitch circle, preventing the product from rotating freely and thus completing the positioning. After positioning, an annular top cover is placed on top, and four pressing components press the annular top cover in place, achieving the effect of rapid tooling and enabling rapid mass production.

[0013] Meanwhile, the annular base plate can be fixed to the worktable of the gear hobbing machine with bolts, eliminating the need to move the worktable and reducing scrap caused by inaccurate tool setting due to human factors, ensuring product qualification rate, and reducing the need to re-set the tool for each product, thus solving the problem of low processing efficiency. The chuck is also fixed to the mounting frame with bolts, which facilitates subsequent disassembly and maintenance. The anti-slip pad increases the friction between the pressing component and the annular top cover, and the three support pillars further increase the overall stability. Attached Figure Description

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.

[0020] This utility model provides a bevel gear inserting fixture that enables product positioning and clamping operations, significantly improving production efficiency and product quality, simplifying the operation process, and making the entire production process more efficient and reliable. Traditional bevel gear inserting fixtures often suffer from inaccurate positioning and poor clamping effects, leading to unstable product quality and low production efficiency. This utility model, through three ring-shaped positioning components, each including a first cylinder and an L-shaped plate with positioning posts mounted on the L-shaped plate, achieves multi-point precise positioning of the product. Each pressing component includes a fixed cover, a motor, a second cylinder, and a pressing plate. When the motor operates, it drives the turntable to rotate, while the second cylinder pushes the pressing plate to move and rotate, thus clamping the annular top cover. This design not only simplifies the clamping operation but also improves the clamping effect, ensuring the stability of the product during processing.

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a tooling for inserting inverted bevel gears, including a chuck 1 and an annular base plate 3. The chuck 1 is located inside the annular base plate 3, and three mounting brackets 4 arranged in a ring are installed on the top outer surface of the annular base plate 3. The mounting brackets 4 are fixedly connected to the chuck 1 by bolts. The chuck 1 is used to place products, and three positioning holes 7 are opened on the bottom inner wall of the chuck 1. Positioning components are installed on one side of the three mounting brackets 4, and the positioning ends of the positioning components are located inside the positioning holes 7. The positioning components are used to position the products. An annular top cover 10 is provided on the outer surface of the chuck 1, and four rectangular pressing components are installed on the top outer surface of the annular base plate 3. The pressing components are used to press the annular top cover 10.

[0022] It should be noted that the product is a raw material that has been processed and formed in one go. This tooling is needed for positioning and reversing the conical teeth. The positioning end of the positioning component is the positioning post 8.

[0023] like Figure 1-3 As shown, three ring-shaped support pillars 2 are installed on the bottom surface of the chuck 1, and a circular opening 9 is provided on the bottom surface of the chuck 1.

[0024] It should be noted that the support column 2 is located inside the annular chassis 3, and the three support columns 2 are staggered with the three mounting brackets 4.

[0025] like Figure 2-3 As shown, all three positioning components include a first cylinder 5, and the first cylinder 5 is fixed on the mounting bracket 4. One end of the piston rod of the first cylinder 5 is fixed with an L-shaped plate 6, and a positioning post 8 is installed on the top surface of the L-shaped plate 6.

[0026] It should be noted that the three locating pins 8 extend into the interior of the chuck 1 to engage with the internal pitch circle of the product.

[0027] like Figure 2-3 As shown, the positioning post 8 and the interior of the positioning port 7 form a sliding fit, and the L-shaped plate 6 and the bottom surface of the chuck 1 form a sliding fit.

[0028] It should be noted that the positioning port 7 is elliptical in shape, and the L-shaped plate 6 can be fixed to one end of the piston rod of the first cylinder 5 with bolts. The positioning column 8 can also be connected to the L-shaped plate 6 with bolts, which facilitates subsequent disassembly and replacement.

[0029] like Figure 1-4 As shown, each of the four pressing components includes a fixed cover 11, which is fixed to the top outer surface of the annular base plate 3. A motor 12 is installed inside the fixed cover 11. A turntable is installed through the output end of the motor 12 through the fixed cover 11. A second cylinder 13 is installed on the top outer surface of the turntable. A pressing plate 14 is installed at the top of the piston rod of the second cylinder 13.

[0030] It should be noted that the fixed cover 11 can be assembled and fixed with bolts, which facilitates the subsequent maintenance of the motor 12. The second cylinder 13 can adjust the height of the lower pressure plate 14, and the motor 12 is used to adjust the position of the lower pressure plate 14 to avoid hindering the disassembly and assembly of the annular top cover 10.

[0031] like Figure 4 As shown, an anti-slip pad is installed on the bottom surface of the lower pressure plate 14. The anti-slip pad contacts the top surface of the annular top cover 10, and the turntable forms a rotational engagement with the top surface of the fixed cover 11.

[0032] It should be noted that the anti-slip pad can be attached to the bottom outer surface of the lower pressure plate 14, and the inner diameter of the annular top cover 10 is adapted to the outer diameter of the chuck 1.

[0033] Working principle: The annular base 3 is fixed on the worktable of the gear shaping machine. The product is then placed into the chuck 1. The three first cylinders 5 retract and drive the three positioning pins 8 to clamp the product onto the inner tooth pitch circle, preventing the product from rotating. Then, the annular top cover 10 is engaged. The four motors 12 drive the lower pressure plate 14 to rotate above the annular top cover 10. Then, the four second cylinders 13 retract and drive the anti-slip pad of the lower pressure plate 14 to adhere to the annular top cover 10, thus completing the entire tooling work. The product can then be processed in conjunction with the gear shaping machine.

[0034] 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.
