Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to a special indexing fixture for processing micro gears. Background Art

[0002] A micro gear is a mechanical part that transmits power, changes speed and torque through the meshing of gear teeth. There are many evenly distributed teeth on the rim, which can transmit power from one shaft to another, and can speed up, slow down and change the direction of movement during the transmission process. Because micro gears are simple in structure and practical, they are indispensable in industrial production and daily life. In order to facilitate the fixation of micro gears during the reproduction process, a special indexing fixture for gear processing micro gears is required.

[0003] The micro gear indexing fixture for gear processing is a special fixture used in the gear processing process. It is mainly used in the manufacture of micro gears. Its core function is to accurately control the indexing of the gear blank during the processing process to ensure the processing accuracy and position accuracy of each tooth.

[0004] The special indexing fixture for gear processing micro gears currently on the market moves toward the middle through two clamping plates to clamp the micro gear blank for subsequent production and processing. When the material of some micro gear blanks is too hard, it will produce greater resistance to the chisel for cutting the micro gear blank. The fixation firmness is insufficient when relying solely on the clamping structure to fix the gear during processing. Especially when processing harder materials, it will cause shaking due to the greater force, and the clamping and processing accuracy will be reduced as a result of the shaking, resulting in the micro gears produced being scrapped due to unqualified products, which will cause waste and increase the cost of using the device. Utility Model Content

[0005] In order to make up for the above deficiencies, the present invention provides a special indexing fixture for gear processing micro gears, aiming to improve the problem of insufficient firmness of the indexing fixture on the gears during gear processing in the prior art.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a special indexing fixture for gear processing micro gears, including a mounting plate, a bidirectional motor is fixedly connected to the inner middle part of the mounting plate, one end of the bidirectional motor passes through the mounting plate and is fixedly connected to a threaded rod, the outer side of the threaded rod is threadedly connected to a lifting block, the outer wall of the lifting block is fixedly connected with a U-shaped block, the inner side of the U-shaped block is rotatably connected to a rotating plate, the outer side of the rotating plate is rotatably connected to a moving rod, a plurality of protective pads are arranged around the top of the mounting plate, the outer sides of the plurality of moving rods are respectively fixedly connected to the corresponding protective pads, and a cooling mechanism is provided at the bottom of the mounting plate, which is used to cool and clean the gears.

[0007] As a further description of the above technical solution:

[0008] The cooling mechanism includes a filter, which is fixedly connected to the other end of the bidirectional motor. The bottom of the mounting plate is fixedly connected to a water tank. The front top of the water tank is connected to a water pump. The output end of the water pump is connected to a hose, and the top of the hose is connected to a spray plate.

[0009] As a further description of the above technical solution:

[0010] A telescopic rod is fixedly connected to the top of the outer wall of the moving rod, and the other end of the telescopic rod is fixedly connected to the lifting block.

[0011] As a further description of the above technical solution:

[0012] The inner wall of the lifting block is slidably connected to guide rods all around, and the bottom of the guide rod is fixedly connected to the mounting plate.

[0013] As a further description of the above technical solution:

[0014] Slide grooves are provided around the top of the mounting plate. Slide blocks are slidably connected to the inner sides of the slide grooves. The tops of the slide blocks are fixedly connected to the moving rods.

[0015] As a further description of the above technical solution:

[0016] The left and right sides of the outer wall of the water tank are both fixedly connected with handles, and the outer sides of the handles are fixedly connected with a sheath.

[0017] As a further description of the above technical solution:

[0021] The utility model has the following beneficial effects:

[0022] 1. In the present invention, after the bidirectional motor is started, it can drive the threaded rod to start rotating. During the rotation of the threaded rod, the lifting block is prompted to move in the up and down directions by virtue of the effect of the threaded connection. When the lifting block moves, the U-shaped block connected to it will be displaced synchronously. This displacement will drive the rotating plate to rotate, and then when the rotating plate rotates, it drives the moving rod to move. In this way, it is possible to stabilize the inner side of the larger gear and fix the outer side of the smaller gear.

[0023] 2. In the present invention, the filter screen is synchronously driven to rotate by starting the bidirectional motor, which can effectively prevent the debris generated during the gear processing from adhering to the filter screen surface, and also prevent the debris from entering the water tank. At the same time, when the water pump is started, the water flow will be drawn into the hose. At this time, the operator only needs to hold the hose and use the spray pipe to clean the debris generated during processing, and in this process, the gear processing can be cooled down.
