Problems solved by technology
[0002] A clamping device is needed to fix the workpiece during the processing of the rotary workpiece. The general clamping device is usually manufactured by the enterprise itself. On a fixture body with a guide column, a round iron is used to make a pressure plate, and one end of the pressure plate is pressed on the On the workpiece, the other end is tightened and fixed with a nut, and the round iron (press plate) and the rotary workpiece to be processed are fixed on the fixture body by clearance fit. In the case of relatively high processing requirements, this kind of positioning accuracy cannot meet the requirements of the product. Processing requirements, not only lead to low machining accuracy of the workpiece, but also waste manpower and material resources

Embodiment Construction
[0010] The specific embodiments of the present invention will be further described below in conjunction with the drawings.
[0011] figure 1 It includes a lower pressing plate 1, an O-ring 2, an upper pressing plate 3, a positioning pin 4, a guide column 5, a nut 6, a workpiece 7, a fixture body 8, a positioning pressing plate 9 and so on.
[0012] Such as figure 1 As shown, the present invention is an automatic centering and pressing fixture, including a fixture body 8, a positioning pressing plate 9, on which a guide post 5 is arranged, and the positioning pressing plate 9 is sleeved on the guide post 5, and is tightened and fixed with a nut 6 The positioning and pressing plate 9 includes a lower pressing plate 1 and an upper pressing plate 3 connected by a positioning pin 4, an O-ring 2 is installed between the lower pressing plate 1 and the upper pressing plate 3, and the O-ring 2 is an elastic ring. There are three positioning pins 4, which are evenly arranged along the outer ...

The invention relates to the technical field of a workpiece clamping. Particularly, the invention relates to an automatic centering compressing clamp. The automatic centering compressing clamp comprises a clamp body and a positioning compressing plate; a guide pillar is arranged on the clamp body, the positioning compressing plate is sleeved on the guide pillar, screwed and fixed by a nut; the positioning compressing plate comprises an upper compressing plate and a lower compressing plate which are connected through a positioning pin; an O-type ring is mounted between the lower compressing plate and the upper compressing plate. By using the automatic centering compressing clamp, a workpiece is mounted and revolved, so that the positioning gap existed when the workpiece is mounted can be removed; thereby the precision of processing the workpiece can be guaranteed; the automatic centering compressing clamp is simple and flexible in structure and relatively low in cost.
Description
Technical field [0001] The invention relates to the technical field of workpiece clamping, in particular to an automatic centering and pressing clamp. Background technique [0002] In the process of rotating workpieces, a clamping device is needed to fix the workpiece. The general pressing device is usually manufactured by the company itself. On a fixture body with a guide column, a round iron is used to make a pressing plate, and one end of the pressing plate is pressed against On the workpiece, the other end is tightened and fixed with a nut. The round iron (press plate) and the rotating workpiece to be processed are fixed on the fixture body by a clearance fit. In the case of relatively high processing requirements, this positioning accuracy cannot meet the requirements of the product. Processing requirements not only lead to low workpiece processing accuracy, but also waste manpower and material resources. Summary of the invention [0003] The purpose of the present invention...
