Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a gear positioning device in a gear processing machine. Background Art

[0002] Gears, as a common transmission component, are an indispensable part of all machines and instruments. Gear processing machines are machine tools for processing the teeth of various cylindrical gears, bevel gears and other toothed parts. Gears can be processed into different tooth shapes by gear processing machines.

[0003] It has been found in actual use that the existing gear processing machines have the following deficiencies in gear positioning:

[0004] When the existing positioning device positions the gear to be processed, the gear needs to be pressed down and clamped on both sides of the gear by a clamping plate. However, the surface of the metal gear is smooth.

[0005] During processing, if the pressing force is small, the gear is easy to slip. If the pressing force is large, the friction between the gear surface and the positioning device and the processing table will produce scratches, which will easily affect the yield rate of gear processing.

[0006] In addition, when the outer side of the gear is cut with this clamping method, the positioning device often affects the tool path, thereby affecting the efficiency of the gear processing;

[0007] Therefore, the present application provides a gear positioning device in a gear processing machine to meet the demand. Utility Model Content

[0008] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a gear positioning device in a gear processing machine.

[0009] The technical problem to be solved by the utility model is to provide a gear positioning device in a gear processing machine to solve the problems of the gear positioning device in the existing gear processing machine.

[0010] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0011] A gear positioning device in a gear processing machine comprises: a machine tool, a machine base, an electric slide, a slider, an electric telescopic rod, a connecting seat, a first clamping block, a second clamping block, a processing table, a support plate, a positioning rod, a fixed sleeve and a limit seat, wherein the machine tool is installed with a machine base at the upper end on the right side, an electric slide is installed horizontally on the side of the machine base, a slider is installed at the inner lower end of the electric slide, an electric telescopic rod is installed vertically at the bottom of the slider, a connecting seat is installed at the other end of the electric telescopic rod, a first clamping block and a second clamping block are installed on the inner side of the connecting seat, a processing table is installed at the middle of the upper end of the machine tool, a support plate is installed at the upper end of the processing table, a positioning rod is installed at the middle of the inner side of the processing table, a fixed sleeve is installed at the outer end of the positioning rod of the processing table, and a limited seat is installed at the outer end of the fixed sleeve.

[0012] Preferably, the connecting seat is disc-shaped, and when the connecting seat is inverted, the first clamping block and the second clamping block extend outward to the outer end of the connecting seat, and the first clamping block and the second clamping block are movably connected to the connecting seat.

[0013] Preferably, the first pressing block and the second pressing block are both in annular shape, and the diameter of the second pressing block is smaller than the diameter of the first pressing block.

[0014] Preferably, the second pressing block is embedded in the inner side of the first pressing block, and the second pressing block is movably connected to the first pressing block.

[0020] 1. Under the downward pressure output by the electric telescopic rod, the gear to be processed is pressed downward by the connecting seat, and the fixed sleeve is compressed downward. The bottom of the semi-spherical fixed sleeve is pressed and collapsed downward along the positioning rod. The upper part of the trumpet-shaped fixed sleeve can fit on the surface of the gear to be processed, increasing the friction between the gear and the fixed sleeve. The negative pressure is formed inside the compressed and collapsed fixed sleeve to adsorb the gear on the upper part of the fixed sleeve, which can avoid slippage during the processing and ensure the processing accuracy and quality of the gear.

[0032] In this embodiment, the connecting seat 6 is disc-shaped. When the connecting seat 6 is hung upside down, the first clamping block 7 and the second clamping block 8 extend outward to the outer end of the connecting seat 6, and the first clamping block 7 and the second clamping block 8 are movably connected to the connecting seat 6. The slider 4 can be moved laterally through the electric slide 3 to adjust the position of the electric telescopic rod 5 and the connecting seat 6, align with the processing table 9 and the positioning rod 11, and the electric telescopic rod 5 extends outward to press the gear to be processed onto the fixed sleeve 12 through the connecting seat 6.

[0033] In this embodiment, the first clamping block 7 and the second clamping block 8 are both in annular shape, and the diameter of the second clamping block 8 is smaller than the diameter of the first clamping block 7. When the connecting seat 6 contacts the gear downward, the diameter of the gear is larger than the diameter of the connecting seat 6. The first clamping block 7 and the second clamping block 8 on the surface of the connecting seat 6 are squeezed and retracted into the connecting seat 6. When the diameter of the gear is smaller than the diameter of the connecting seat 6, the annular first clamping block 7 and the second clamping block 8 are pressed on the gear by their own gravity, so that in the link of cutting the gear to be processed, the gear is fixed from the axial center hole and processed around the periphery of the gear, thereby avoiding interference between the tool and the fixing mechanism when processing the gear teeth. In addition, the setting of the fixing mechanism can fix gear workpieces of different sizes, which is beneficial to improving the practicality of the device.

[0034] In this embodiment, the second clamping block 8 is embedded in the inner side of the first clamping block 7, and the second clamping block 8 and the first clamping block 7 are movably connected. When the diameter of the gear is at different sizes, it can be pressed by the second clamping block 8 and the first clamping block 7 of different diameters.

[0035] In this embodiment, a docking groove 801 is provided in the middle of the second clamping block 8, and the docking groove 801 fits with the positioning rod 11. When the gear is docked and pressed up and down, the docking groove 801 in the middle of the second clamping block 8 can dock with the positioning rod 11, so that the gear is fixed on the positioning rod 11.

[0036] In this embodiment, the fixed sleeve 12 is made of rubber material, and the positioning rod 11 passes through the fixed sleeve 12 and extends vertically outward to the outer ends of the processing table 9 and the support plate 10.

After the bottom of the semi-spherical fixed sleeve 12 is pressed, it shrinks downward along the positioning rod 11, and the upper part of the trumpet-shaped fixed sleeve 12 can fit on the surface of the gear to be processed, thereby increasing the friction between the gear and the fixed sleeve 12. Negative pressure is formed inside the pressed and collapsed fixed sleeve 12 to adsorb the gear to the upper part of the fixed sleeve 12, which can avoid slippage during the processing and ensure the gear processing accuracy and quality.

[0038] In this embodiment, the upper end of the fixed sleeve 12 is supported on the upper end of the support plate 10, and the limit seat 13 is sleeved on the lower end of the fixed sleeve 12, so that when the gear is placed on the support plate 10, it can directly fit on the upper end of the fixed sleeve 12. The gear is supported by the fixed sleeve 12, and the position of the fixed sleeve 12 that is pressed and collapsed can be maintained at the lower part through the limit seat 13. After the pressing force is lost, the bottom of the fixed sleeve 12 naturally stretches and returns to its original position, preparing for the adsorption of the next group of gears.
