Description

Technical Field

[0001] This utility model relates to the field of gear clamping technology, and in particular to a clamping fixture for gear production. Background Technology

[0002] A gear is a mechanical component consisting of a series of teeth arranged on a circular rim. These teeth mesh with the teeth of another gear, thereby enabling motion and power transmission between two shafts. Gear design is crucial because it directly affects the efficiency and performance of a mechanical system. Gear teeth can be straight, involute, or other complex shapes, depending on the specific function required and the load conditions. Gears are widely used in various machines and equipment, such as automotive transmissions, bicycle chains, and industrial machinery, where they can change the direction of rotation, speed, and torque.

[0003] In the gear manufacturing process, to ensure the stability of the connection between the gear and the machining platform, fixtures are usually used for limiting and fixing. Most existing gear fixtures use pitch adjustment to clamp gears of different specifications. Although this method of fixing fixtures is simple in structure and easy to operate, it lacks the function of displaying the pitch adjustment value in real time. Operators cannot directly know the specific adjustment value. At the same time, the existing fixture design does not take into account the convenience of disassembling, connecting, or repairing and replacing the clamping parts according to usage needs. This makes it impossible to flexibly change clamping parts of different sizes when dealing with different shapes and specifications of gears.

[0004] Therefore, existing fixtures may lack sufficient adaptability and flexibility in certain specific application scenarios, limiting their application in high-precision or variable production needs. To address this, we propose a fixture for gear production. Utility Model Content

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.

[0029] Example: Refer to Figures 1 to 7This utility model provides an embodiment of a gear production fixture, including a pitch adjustment frame 1. Two sets of gear clamping assemblies 2 are connected to the bottom of the pitch adjustment frame 1. Each gear clamping assembly 2 includes a first guide member 3, a second guide member 4 mounted at the bottom of the first guide member 3, and a gear clamping component 5 at the bottom of the second guide member 4. The gear clamping component 5 includes a connecting disc 6, and a clamping disc 7 is dampedly connected to the bottom of the connecting disc 6.

The gear clamping component 5, through the small arc groove 8, medium arc groove 9, and large arc groove 10 opened on one side of the clamping disc 7, allows the clamping disc 7 to clamp and fix gears of small, medium, and large specifications according to the usage. By adding limiting teeth 11 to the inner wall of the small arc groove 8, medium arc groove 9, and large arc groove 10, the limiting teeth 11 match the tooth shape of the gear, ensuring that the gear will not slip or loosen during the clamping process. Through the interlocking structure between the rotating plate 19 and the rotating jaw 13, the gear clamping component 2 can also quickly disassemble and assemble the clamping disc 7 according to the usage, so that different models of clamping disc 7 can be replaced according to the shape and specifications of the gear.

[0030] A mounting groove 12 is provided on the top of the connecting disc 6. A rotating bayonet 13 is provided around the inner wall of the mounting groove 12.

Different models of clamping discs can be replaced according to the shape and specifications of the gears. 7. A transmission toothed plate 20 is connected to one side of the first guide member 3. A plate groove 21 is opened through the first guide member 3 near the transmission toothed plate 20. The plate groove 21 is structurally matched with the transmission toothed plate 20. The plate groove 21 and the transmission toothed plate 20 are plugged into each other. Indicator plates 22 are installed at both ends of the first guide member 3. Rollers 23 are rotatably connected to both ends of the first guide member 3 near the indicator plates 22. The transmission toothed plate 20 installed on one side of the first guide member 3 can play a transmission role on the top of the clamping disc 7 with adjustable spacing.

[0032] A motor drive box 24 is installed at one end of the top of the spacing adjustment frame 1. A transmission wheel 25 is rotatably connected to the middle of the top of the spacing adjustment frame 1. A transmission belt 26 connects the transmission wheel 25 to the transmission wheel 25. A spacing adjustment groove 27 is opened through one side of the spacing adjustment frame 1. The spacing adjustment groove 27 matches the structure of the first guide member 3 and the second guide member 4. The spacing adjustment groove 27 is in sliding fit with the first guide member 3 and the second guide member 4. Through the structural design of the sliding fit between the spacing adjustment groove 27 and the first guide member 3 and the second guide member 4, the two sets of gear clamping assemblies 2 can be slidably limited to the bottom sides of the spacing adjustment frame 1. A drive gear 28 is connected to one end of the transmission wheel 25. The drive gear 28 and the transmission gear plate 20 are connected to the transmission wheel 25. The structures are matched, with the drive gear 28 and the transmission gear plate 20 meshing together. The drive gear 28 is connected to the middle of the spacing adjustment groove 27. Spacing scale marks 29 are provided on both sides of the spacing adjustment groove 27. The bottom of the spacing adjustment frame 1 is also connected to the guide slide rod 30. The guide slide rod 30 and the guide slide hole 17 are structurally matched and have a sliding fit. Through the meshing connection between the drive gear 28 and the transmission gear plate 20, when the motor drive box 24 is powered on, it can drive the drive gear 28 to rotate, thereby driving the two sets of gear clamping assemblies 2 to make relative or opposite adjustments in the horizontal direction. Thus, the clamping distance between the two sets of clamping discs 7 can be adjusted according to the size of the gears.

[0033] Working principle: This solution uses two sets of gear clamping assemblies 2 added to the bottom of the spacing adjustment frame 1. Each gear clamping assembly 2 consists of a first guide 3, a second guide 4, and a gear clamping component 5. The gear clamping component 5 uses small arc-shaped grooves 8, medium arc-shaped grooves 9, and large arc-shaped grooves 10 opened on one side of the clamping disc 7 to clamp and fix gears of small, medium, and large specifications according to the usage. Limiting teeth 11 are added to the inner walls of the small arc-shaped grooves 8, medium arc-shaped grooves 9, and large arc-shaped grooves 10. The limiting tooth 11 matches the tooth profile of the gear, ensuring that the gear will not slip or loosen during clamping. In conjunction with the matching structure of the mounting plate 18 and the mounting groove 12, and the snap-fit ​​structure between the rotating clamping plate 19 and the rotating jaw 13, the gear clamping assembly 2 can also quickly disassemble and assemble the clamping disc 7 according to the usage situation. This allows for the replacement of different models of clamping discs 7 according to the shape and specifications of the gear, thereby improving the practicality and flexibility of the equipment in the field of gear clamping technology.

[0034] This solution uses a transmission gear plate 20 added to one side of the second guide 4 and a drive gear 28 connected to one end of the transmission wheel 25. Since the drive gear 28 and the transmission gear plate 20 are meshed, when the motor drive box 24 is powered on and drives the drive gear 28 to rotate in the forward or reverse direction, it can drive the two sets of gear clamping assemblies 2 to move and adjust in the horizontal direction relative to or opposite to each other. This allows the gear clamp to adjust the clamping distance between the two sets of clamping discs 7 according to the size of the gear to be fixed. With the indicator plates 22 added to both ends of the first guide 3 and the spacing scale marks 29 set on both sides of the spacing adjustment frame 1, the value of the clamping distance between the two sets of clamping discs 7 after adjustment can be displayed in real time, which is convenient for the staff to record.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
