Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-3, an automobile hub clamp comprises a machine table 1, a pressing assembly 2 and a centering chuck 3, the pressing assembly 2 and the centering chuck 3 are installed on the upper end surface of the machine table 1, three the pressing assembly 2 is uniformly distributed on a circumference with the centering chuck 3 as a circle center, the pressing assembly 2 comprises a cylinder 21, a motor 22 and a pressing piece 23, one end of the cylinder 21 is fixedly connected with the machine table 1, the output end of the cylinder 21 is connected with the motor 22, and the output end of the motor 22 is perpendicularly connected with one end of the pressing piece 23. Specifically, in this embodiment, centering chuck 3 and compress tightly subassembly 2 and all be through bolt fixed mounting on the up end of board 1 to three compress tightly subassembly 2 and evenly arrange on the circumference that uses centering chuck 3 as the centre of a circle, be convenient for fix and be cylindric wheel hub. When the staff lay wheel hub (not shown in the figure) on centering chuck 3, centering chuck 3 prevents wheel hub free rotation with the inside wall butt of wheel hub. Further, in order to prevent the hub from jumping due to vibration during machining, the pressing assembly 2 presses the upper end surface of the hub. In order to adapt to hubs of different sizes, the height of the pressure piece 23 in the vertical direction is adjusted by means of the cylinder 21. It can be understood that, when the compressing piece 23 closely butts on the upper end face of the hub under the action of the cylinder 21, the hub can be locked by the centering chuck 3 in cooperation with the compressing assembly 2, the stability is good, and the hub can not generate large displacement and jump even if being vibrated during processing, thereby improving the processing precision. Meanwhile, in order to prevent the pressing piece 23 from blocking workers to take out the hub, the motor 22 is connected with the pressing piece 23, and the position of the pressing piece 23 can be adjusted on the horizontal plane when the motor 22 works, so that the use is more convenient.

As shown in fig. 1 to 3, the centering chuck 3 includes a chuck 31 and a fine adjustment platform 32, and the chuck 31 is connected to the machine table 1 through the fine adjustment platform 32. Specifically, the heights of different hubs are different, and in order to enable the chuck 31 to be tightly abutted to the upper part of the inner side wall of the hub, the fixed chuck 31 is installed by using the fine adjustment platform 32, and the fine adjustment platform 32 adjusts the position of the chuck 31 in the vertical direction.

As shown in fig. 1 to 3, three jaws 311 are movably disposed at one end of the chuck 31 away from the fine adjustment platform 32, and the jaws 311 perform reciprocating linear motion along the radial direction of the chuck 31.
