Description

Technical Field

[0001] The utility model relates to the field of rotor shaft workpiece processing, in particular to a fixing fixture for an automobile rotor shaft workpiece. Background Art

[0002] With the continuous progress of society, the use of automobiles has become one of the indispensable means of transportation. The use of rotor shafts in automobiles is indispensable. When machining rotor shafts, they need to be positioned and clamped to facilitate machining and operation.

[0003] Chinese patent authorization application number: CN201820907900.8 provides a rotor processing jig for automotive transmission. The limit blocks of this solution are used to prevent mistakes in the tooling to prevent scrap caused by human errors. This is an important way to control and improve product efficiency. Improvements are made to the fixture structure. The flat pads reduce the contact range of the product, directly improve the processing quality of the product, and reduce the quality risks in the clamping. The clamping adopts the method of fixing with an expansion sleeve combined with a torque wrench (limited value), which avoids the problem of uneven human force and product damage. This set of jigs can use flat pads to adjust the corresponding hole size and position to process a variety of products of this type, and it has high versatility. This set of combined jigs is simple to make, easy to use, precise in positioning, and highly adaptable. With this structural fixture, slight adjustments can be made to achieve the processing of different types of workpieces.

[0004] The existing automobile rotor shaft workpiece has certain disadvantages when positioning. First, during the clamping process of the automobile rotor shaft workpiece, the fixture structure is relatively simple and can only be clamped at both ends of the automobile rotor shaft workpiece, with low stability. When the automobile rotor shaft workpiece is processed externally, the workpiece cannot be limited more stably, which affects the clamping and positioning effect of the automobile rotor shaft workpiece. For this reason, we propose a fixing fixture for the automobile rotor shaft workpiece. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of the present utility model is to provide a fixing fixture for an automobile rotor shaft workpiece. By setting a sliding rod and a positioning ring, the positioning frame can perform preliminary positioning when the fixture is used, and the adjusting block is adjusted to cause the sliding rod to move and drive the limiting ring. The limiting ring can be adjusted to different lengths and positioned at the outer end of the workpiece again, so that the device has a multiple clamping structure, and the positioning ring can be adjusted in position, which is convenient for positioning and clamping workpieces of different diameters, making the fixing fixture more practical in automobile rotor shaft workpiece processing.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:
