Description

Technical Field

[0001] The utility model relates to the technical field of spiral bevel gear processing, and particularly relates to a central fixing structure for spiral bevel gear processing. Background Technique

[0002] A spiral bevel gear is a conical gear shaped like an umbrella. It has low noise and smooth transmission during movement. Compared with a belt, it has a smaller use space, better transmission performance, and a longer service life. Therefore, most machinery now uses spiral bevel gears for transmission.

[0003] In the prior art, Chinese Patent No. CN219119747U discloses a spiral bevel gear that is easy to install, including a spiral bevel gear body sleeved at the end of a rotating rod. A limiting plate fixed on the rotating rod abuts against the bottom of the spiral bevel gear body. A pressing plate is arranged above the spiral bevel gear body. A threaded column is fixed on the pressing plate. A threaded hole matching the threaded column is opened at the top end of the rotating rod. An annular baffle fixed on the pressing plate is arranged outside the threaded column. An insertion groove is opened at the top of the spiral bevel gear body. A clamping assembly is arranged at the bottom end of the annular baffle. A clamping groove is arranged on the rotating rod. By setting the limiting plate and the pressing plate, the spiral bevel gear body is prevented from moving up and down on the rotating rod, improving the stability of assembly. By setting the annular baffle, the clamping assembly, the clamping groove and the insertion groove, the spiral bevel gear body is prevented from generating radial runout, and the setting of fine structures is reduced, effectively reducing the processing difficulty.

[0004] During the use of the above device, the spiral bevel gear is clamped by the clamping assembly. However, the clamping assembly uses groove clamping and fixing, which easily causes the spiral bevel gear to fall off during processing, and it is inconvenient to take the spiral bevel gear during processing. Therefore, when the spiral bevel gear is processed, it is easy to fall off and cause defective products. Content of the Utility Model

[0005] The purpose of the utility model is to provide a central fixing structure for spiral bevel gear processing to solve the problem that the spiral bevel gear is easy to fall off during processing as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A central fixing structure for spiral bevel gear processing, including a protective shell and a base, the protective shell is vertically installed on the upper surface of the base, and is characterized in that it further includes:

[0007] A support plate is fixedly installed on the lower surface of the base, a stepping motor is fixedly installed on the lower surface of the support plate, and a rotating mechanism that rotates automatically is arranged between the base and the stepping motor;

[0008] A partition board is rotatably installed on the inner side surface of the base, a rotating column is rotatably installed on the inner side surface of the partition board, and a fixing mechanism for automatic clamping is arranged between the base and the rotating column.

[0009] Furthermore, a rotating shaft is rotatably installed on the inner side surface of the stepping motor, a support plate is fixedly installed on the upper surface of the stepping motor, and a partition board is fixedly installed on the upper surface of the support plate.

[0010] Furthermore, a limiting block is fixedly installed on the upper surface of the rotating shaft, a slot hole is formed in the limiting block, and the outer surface of the rotating shaft is rotatably installed in the slot hole.

[0011] Furthermore, a fixing disk is rotatably installed on the outer surface of the rotating shaft. The rotating structure includes evenly arranged connecting rods fixedly installed on the outer surface of the fixing disk, evenly arranged paddles fixedly installed on the outer surface of the connecting rods, and a rotating structure is formed between the rotating shaft and the fixing disk.

[0012] Furthermore, a discharge baffle is fixedly installed on the outer surface of the base, and a concave card slot is formed in the discharge baffle.

[0013] Furthermore, a fixing shaft is fixedly installed on the inner side surface of the connecting piece. The fixing mechanism includes a fixing piece fixedly installed on the outer surface of the fixing shaft, a fixing cone fixedly installed on the lower surface of the fixing piece, and a clamping structure is formed between the connecting piece and the fixing piece.

[0014] Furthermore, a rotating block is rotatably installed on the outer surface of the rotating column, evenly arranged connecting pieces are fixedly installed on the outer surface of the rotating block, and a fixing sleeve is fixedly installed on the upper surface of the rotating column.

[0015] Compared with the prior art, the beneficial effect of the present utility model is that for the central fixing structure for spiral bevel gear processing, when the stepping motor is started, the rotating mechanism is driven by the stepping motor to rotate. Under the acting force of the rotation of the rotating mechanism, the rotating mechanism drives the fixing mechanism to lift and lower during rotation, and the spiral bevel gear is fixed by the downward pressure of up and down telescoping, so as to achieve the purpose of fixing the spiral bevel gear.

[0016] Furthermore, the rotating mechanism is driven to rotate by the stepping motor. Under the acting force of the rotational force of the stepping motor, the paddle drives the spiral bevel gear to rotate, so that the fixing mechanism presses down to fix the spiral bevel gear. When the spiral bevel gear processing is completed, the fixing mechanism rises to release the spiral bevel gear, and the paddle drives the spiral bevel gear to move, so as to discharge the spiral bevel gear into the discharge baffle, which is convenient for personnel to take.

Specific embodiments

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment 1: Please refer to Figure 1-6 , the present invention provides the following technical solutions: A central fixing structure for spiral bevel gear processing, including a protective case 1 and a base 2. The protective case 1 is vertically installed on the upper surface of the base 2. It is characterized in that a support plate 12 is fixedly installed on the lower surface of the base 2, a step motor 18 is fixedly installed on the lower surface of the support plate 12, and a rotating mechanism for automatic rotation is provided between the base 2 and the step motor 18; a partition plate 13 is rotatably installed on the inner side surface of the base 2, a rotating column 4 is rotatably installed on the inner side surface of the partition plate 13, and a fixing mechanism for automatic clamping is provided between the base 2 and the rotating column 4.

[0026] First, start the stepping motor 18. Drive the automatically rotating rotating structure arranged between the base 2 and the stepping motor 18 to rotate through the stepping motor 18. An automatically rotating rotating structure is arranged between the base 2 and the stepping motor 18, and an automatically clamping fixing mechanism is arranged between the base 2 and the rotating column 4 to fix. Under the acting force of the rotation of the rotating mechanism, the rotating mechanism drives the fixing mechanism to lift and lower during rotation, and uses the downward pressure of the up and down telescoping to fix the spiral bevel gear, thereby fixing the spiral bevel gear and preventing the spiral bevel gear from shaking during processing, resulting in defective products.

[0027] Embodiment 2: On the basis of Embodiment 1, a fixing disk 16 is also disclosed. Its specific structure is as follows: A rotating shaft 11 is rotatably installed on the inner side surface of the stepping motor 18. A support plate 12 is fixedly installed on the upper surface of the stepping motor 18. An isolation plate 13 is fixedly installed on the upper surface of the support plate 12. A limiting block 10 is fixedly installed on the upper surface of the rotating shaft 11. The limiting block 10 is provided with a slot hole, and the outer surface of the rotating shaft 11 is rotatably installed in the slot hole. A fixing disk 16 is rotatably installed on the outer surface of the rotating shaft 11. The rotating structure includes that uniformly arranged connecting rods 15 are fixedly installed on the outer surface of the fixing disk 16. Uniformly arranged paddles 14 are fixedly installed on the outer surface of the connecting rods 15, and a rotating structure is formed between the rotating shaft 11 and the fixing disk 16.

[0028] By starting the stepping motor 18, the stepping motor 18 drives the rotating shaft 11 to rotate. The support plate 12 supports the isolation plate 13. The isolation plate 13 prevents the spiral bevel gear from falling during processing. The rotating shaft 11 drives the limiting block 10 to rotate. The limiting block 10 prevents the rotating shaft 11 from falling off during rotation, and the rotating shaft 11 also drives the fixing disk 16 to rotate. The fixing disk 16 drives the connecting rods 15 to rotate. The connecting rods 15 drive the paddles 14. When the spiral bevel gear is placed through the opening above the protective shell 1, the paddles 14 drive the spiral bevel gear to rotate, thus facilitating the processing of the spiral bevel gear. The processed spiral bevel gear is discharged by the paddles 14, thus facilitating the taking by personnel.

[0029] Embodiment 3: On the basis of Embodiment 1, a fixing cone 9 is also disclosed. Its specific structure is as follows: A discharge baffle 17 is fixedly installed on the outer surface of the base 2. The discharge baffle 17 is provided with a concave card slot.

A fixing sleeve 3 is fixedly installed on the upper surface of the rotating column 4.

[0030] After the spiral bevel gear is placed inside the base 2, the stepping motor 18 drives the paddle 14 to rotate. The paddle 14 drives the spiral bevel gear to rotate. The rotating shaft 11 drives the rotating column 4 to rotate. The fixed sleeve 3 protects the rotating column 4 from falling off during rotation, which may cause the fixed cone 9 to be unable to fix the spiral bevel gear. The rotating column 4 drives the rotating block 5 to move up and down. The rotating block 5 drives the connecting piece 6 to move up and down. The connecting piece 6 drives the fixed shaft 7 to rotate and move up and down. The fixed shaft 7 drives the fixing piece 8 to rotate and move up and down. The fixing piece 8 drives the fixed cone 9 to clamp and fix the spiral bevel gear, thus preventing the spiral bevel gear from shaking and falling off during processing, which may lead to the failure of spiral bevel gear processing and make it a defective product. After the spiral bevel gear is processed, the paddle 14 rotates to drive the spiral bevel gear into the discharge baffle 17, thereby discharging the processed spiral bevel gear, which is convenient for personnel to pick up.
