Gear drilling fixing device

Technical Field

The utility model discloses the application relates to gear manufacturing installation field, concretely relates to gear drilling fixing device.

Background

The gear is a mechanical element with teeth on a rim capable of continuously meshing and transmitting motion and power, and the use of the gear plays an important role for most mechanical devices. Therefore, the machining and manufacturing of the gear are strict, and after the gear is cast, holes need to be drilled on the end face of the gear, so that lubricating oil and the like can be conveniently injected. During drilling, the gear needs to be clamped. In the prior art, clamping jaws or other clamps are used for clamping the circumference of a gear, so that the gear tooth root is easy to damage on one hand, and different clamps are needed for clamping different types of gears, so that different clamps are needed to be manufactured, and resources are wasted. The clamping of gear now mostly adopts anchor clamps to press from both sides tightly at the gear upper end. However, when the gear is fixed by the conventional clamp, the pressing plate needs to be manually pressed by an inner hexagonal wrench manually, and after the gear is machined, the screw needs to be manually unscrewed to take down the product, so that the consumed time is 20 seconds and the efficiency is low.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a gear drilling fixing device adopts the device can improve the fixed efficiency when gear drilling.

Further, a supporting plate is arranged at one end of the base, and the clamping plate is connected with the supporting plate in a sliding mode. When the gear needs to be clamped, the clamping plate can be slid downwards along the supporting plate, and after drilling is completed, the clamping plate can be slid upwards along the supporting plate.

Furthermore, an electromagnet is arranged at the upper end of the supporting plate, and a press switch for controlling the on-off state of the electromagnet is arranged in the placing groove; and a magnetic part attracted with the electromagnet is arranged in the clamping plate. After the gear is placed in the placing groove, the press switch can be pressed under the pressure of the corner cylinder, and the electromagnet is powered off. After drilling is finished, the output shaft of the corner cylinder moves upwards and rotates, the pressure of the corner cylinder is not applied, the switch is pressed to reset, and the electromagnet is electrified and generates magnetic force. Because the magnetic force of the electromagnet is attracted with the magnetic part, the magnetic part drives the clamping plate to slide upwards along the supporting plate, the clamping plate does not need to be taken and placed manually, and the operation is convenient.

Further, still include the connecting rod, connecting rod one end is connected with the clamp plate, connecting rod other end backup pad sliding connection. The clamping plate can be ensured to be positioned at the upper end of the central shaft of the gear, so that the clamping effect is better.

Furthermore, the supporting plate end face is provided with a sliding groove, the end part of the connecting rod is rotatably connected with a roller, and the roller is positioned in the sliding groove and is in sliding fit with the sliding groove. The sliding fit of the clamping plate and the supporting plate is realized through the matching of the roller and the sliding groove, the structure is simple, and the friction force is reduced.

Furthermore, a pressing block is arranged below the output shaft of the corner cylinder and is in a circular truncated cone shape. The press block is arranged, so that the stress area of the output shaft of the corner cylinder on the clamping plate can be increased, and the fixing effect is better.
