Description

Technical Field

[0001] The utility model relates to the technical field of gear fixtures, in particular to a fixture for turning the inner hole of a spiral bevel gear. Background Art

[0002] Spiral bevel gear is a transmission component that can transmit smoothly and with low noise at a stable transmission ratio. It has different names in different regions, also known as spiral bevel gear, arc bevel gear, arc bevel gear, circular arc bevel gear, spiral bevel gear, etc.

[0003] During the processing of spiral bevel gears, the gears need to be ground and processed, so a fixture is needed to clamp and fix the gears. Current fixtures generally clamp and fix the outer tooth surface of the gear directly. This can easily damage the surface accuracy of the outer tooth surface of the gear during the processing of the inner hole of the gear, making the operation more troublesome. Utility Model Content

[0004] In view of the above situation, in order to remedy the above existing defects, the utility model provides a spiral bevel gear inner hole turning fixture.

[0005] The utility model provides the following technical solutions: the utility model proposes a spiral bevel gear inner hole turning fixture, comprising a support frame, the support frame is provided with a fixed component, the support frame is provided with a multi-purpose component, the multi-purpose components are symmetrically arranged on both sides of the fixed component; the fixed component comprises a telescopic rod, the telescopic rod is arranged under the support frame, the output end of the telescopic rod is arranged in the support frame, the output end of the telescopic rod is connected to a lifting plate, the lifting plate is provided with an inner hole fixing piece, and a fixing block is provided on the side opposite to the telescopic rod in the support frame.

[0006] Furthermore, the inner hole fixing part includes a driving motor, the driving motor is arranged on the lifting plate, the output end of the driving motor is connected to a bidirectional screw, a bidirectional screw pair is symmetrically sleeved under the bidirectional screw, a hinge block is symmetrically arranged on the side of the bidirectional screw pair, a torsion spring is arranged on the hinge block, a hinge rod is hinged on the hinge block, the hinge rod is connected to the torsion spring, the end of the hinge rod away from the hinge block is hinged to a connecting block, the end of the connecting block away from the hinge rod is connected to a fixing plate, the bidirectional screw is symmetrically provided with auxiliary rods, the auxiliary rods are provided with two groups, the auxiliary rods are arranged between the bidirectional screw pairs, the end of the auxiliary rod away from the bidirectional screw is arranged on one side of the hinge rod, a limit plate is arranged on the side of the bidirectional screw pair, the limit plate is arranged on the side of the hinge block away from the auxiliary rod, and the limit plate is away from the bidirectional screw pair One end of is arranged on one side of the hinge rod, so that the inner hole of the gear passes through the fixing assembly and falls on the multi-purpose assembly, and the telescopic rod is started, and the telescopic rod moves with the lifting plate in the direction close to the fixing block, and the lifting plate moves with the inner hole fixing part in the direction close to the fixing block, so that the end of the two-way lead screw away from the driving motor is inserted into the fixing block to increase the stability of the inner hole fixing part during the fixing process, and then the driving motor is started, and the driving motor drives the two-way lead screw to rotate. It is known from the current technology that the two-way lead screw drives the two-way lead screw pair to move toward each other during the rotation process, and the hinge rod changes from an inclined state to a horizontal state under the obstruction of the auxiliary rod, and at the same time, the fixing plate slowly contacts with the inner hole wall of the gear, and finally the inner hole wall of the gear is supported by the hinge rod and the fixing plate, thereby realizing the fixing effect on the gear, and the gear is very convenient for end face processing and tooth surface processing.

[0007] The multi-purpose component comprises an electric wire plate, which is symmetrically arranged on the side of the support frame close to the fixed block, and the electric wire plate is also arranged on the adjacent sides of the support frame and the fixed block and on both sides of the two-way lead screw. The electric wire plate is evenly provided with electric wire coils, and guide rods are connected between the electric wire plates. The guide rods are symmetrically and movably sleeved with magnetic plates, and fixed rods are symmetrically arranged on the side of the magnetic plate close to the two-way lead screw. When the gear is fed, the electric wire coil is energized to generate a magnetic field around the electric wire coil, so that a repulsive force is generated between the magnetic plate close to the driving motor and the electric wire coil. In this way, when the gear is fed, the fixed rod can support the gear, and at the same time, the magnetic plate far away from the driving motor and the electric wire coil generate an attractive force to avoid the gear being obstructed by the fixed rod when feeding. When it is necessary to process the tooth surface of the gear, the two groups of magnetic plates can generate a repulsive force with the electric wire coil at the same time, and the gear end face can be clamped between the fixed rods to assist the fixing component in fixing the gear, thereby further improving the stability of the gear during processing.

[0008] Preferably, the support frame is connected with a connecting piece to facilitate the connection and use of the device with other equipment, thereby increasing the practicability of the device.

[0009] Furthermore, the fixing plate is arranged in an arc-shaped structure, which increases the contact area between the fixing plate and the inner hole wall of the gear, so that the gear is fixed more firmly.

[0010] Wherein, the driving motor is a servo motor, which is convenient for adjusting the moving distance of the bidirectional screw pair according to the size of the inner hole of the gear, and the device can fix gears with different inner hole diameters.

[0011] The spiral bevel gear inner hole turning fixture proposed by the utility model using the above structure has the following beneficial effects:

[0012] 1. The fixing component is used to fix the gear. It is very convenient to process the end face or the tooth surface of the gear. Moreover, the gears with different inner hole diameters can be fixed by adjusting the distance of the two-way lead screw pair.
