Detailed ways

In order to further understand the features, technical means, and specific objectives and functions of the utility model, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 and 2, the utility model discloses a balanced gear processing fixture, a balanced gear processing fixture, including an outer shell 1, an elastic positioning disc 6 is installed on the end surface of the outer shell 1, and the outer shell 1 There are a connecting rod 7, a pull rod 2 and a bumper 9 inside. The claw 3 is installed on the end face of the outer shell 1 on the pull rod 2. One end of the connecting rod 7 is connected with the bumper 9, and the other end of the connecting rod 7 is along the outer shell 1. The axial direction extends outwards and connects with external equipment. The bumper 9 is facing the elastic positioning disc 6. The elastic positioning disc 6 is provided with at least two positioning blocks 8. The tie rod 2 is fixedly connected with the connecting rod 7 through the connecting rod.

Initially, the connecting rod is pushed by the thrust to drive the bumper to hit and withstand the elastic positioning plate, so that the elastic positioning plate is deformed forward. At this time, at least two positioning blocks are lifted up at a certain angle, which is convenient for placing the workpiece. After the workpiece is placed on the elastic positioning disc and clamped in at least two positioning blocks, the connecting rod is pulled back so that the impact block no longer exerts a driving force on the elastic positioning disc, so that the elastic positioning disc resets and drives at least two positioning blocks The abutment presses the outer peripheral surface of the workpiece, so that the workpiece is firmly positioned.

The outer casing 1 is provided with a mounting column 2, and the claw 3 is locked with the mounting column 2 by a screw, so that the claw can be rotated conveniently.

At least one claw is provided, and when there are at least two claws, the two or more claws are evenly distributed on the end surface of the outer casing. In this embodiment, there are three claws and three positioning blocks on the elastic positioning plate, and the claws and the positioning are staggered.

In addition, a positioning pin 4 for abutting against the workpiece 5 is also provided on the end surface of the outer shell 1 at a position corresponding to the claw 3 . The number of positioning pins is consistent with the number of claws. One end surface of the workpiece is pushed against by the positioning pin, and the other symmetrical end surface is clamped by the jaws, so that the front and rear ends of the workpiece are stressed, and the deformation of the workpiece due to the pressure of the jaws is avoided.

The elastic positioning disc is locked on the end surface of the outer casing by screws. The elastic positioning plate is made of spring steel, which has sufficient strength and meets the requirements of elasticity.

The connecting rod is installed and connected to the center of the elastic positioning disc, and can be locked by screws. The positioning block and the elastic positioning plate are integrally formed.

In the utility model, when the workpiece needs to be placed, a thrust is first applied to the connecting rod, so that the connecting rod drives the bumper to push the elastic positioning plate forward, and the elastic positioning plate deforms and bends forward to a certain radian, so that the positioning block tilts up and tilts up at a certain angle At the same time, the connecting rod also drives the pull rod to move forward, so that the snapper protrudes forward, puts the workpiece on the elastic positioning plate, and then pulls the connecting rod downward, so that the impact block no longer exerts a driving force on the elastic positioning plate, and the elastic The positioning plate returns to the vertical state, and the positioning block presses the workpiece downward, and is tightened from the end face of the workpiece. At the same time, the pull rod is also driven to move backward, and the snapper clamps the workpiece from the outer peripheral surface of the workpiece. Therefore, there is pressure from both radial and axial directions at the same time, ensuring the stable clamping of the workpiece and the accuracy of subsequent processing.

It should be noted that the above are only preferred embodiments of the utility model, and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the embodiments, it is still possible for those skilled in the art Modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features, but within the spirit and principles of the present utility model, any modifications, equivalent replacements, improvements, etc., shall be included in the Within the protection scope of the present utility model.
