Abstract
The utility model relates to a four-bar linkage centering fixture, which is characterized by comprising a base, a guide way arranged on the base, two fastening V-shaped irons arranged on the guide way, an oil cylinder with two ends respectively connected with the fastening V-shaped irons, and a central shaft fixedly connected with the body of the four-bar linkage centering fixture, wherein the fastening V-shaped iron is connected with a three-hole plated through a connecting rod. The utility model effectively improves the positioning precision, makes the repetitive positioning accuracy less than and equal to 0.01, is easy and convenient to manufacture and process, is easy to popularize, can be widely applied to a mechanical processing machine, a mechanical processing center and any other equipment with the workpieces which can not rotate, and has good use effect.
Description
Technical field
The present invention relates to the centralizer of holding workpiece on a kind of machining apparatus, design a kind of four-bar linkage centralizer especially.
Background technology
In the prior art, centralizer adopts gear ﹠ rack structure or positive and negative threaded screw rod structure usually, realizes sliding the relatively moving of two seats, and its trueness error is very big, and the manufacturing process complexity, and difficulty of processing is big.
Summary of the invention
The purpose of this utility model is exactly in order to solve above-mentioned existing issue, and a kind of four-bar linkage centralizer is provided, its positioning accuracy height, and error is little, and manufacturing process is simple, handled easily.
The technical scheme that the utility model solves the problems of the technologies described above is: a kind of four-bar linkage centralizer, it is characterized in that: its by the guide rail of installing on base, the base, be installed on two securing member v blocks on the guide rail, the oil cylinder of fixedlying connected with v block respectively in two ends, the central shaft of fixedlying connected and form with clamp body, v block is connected with three orifice plates by connecting rod.
The rear portion of above-mentioned two v blocks has riser, gripper shoe to connect.
The beneficial effect of the utility model special milling cutter for helical rotor milling: improved positioning accuracy effectively, make repetitive positioning accuracy≤0.01, easy, the handling ease of manufacturing process, be easy to promote, can extensively be used on the equipment that workpiece such as mechanical processing machine, machining center do not rotate, result of use is good.
Description of drawings
Fig. 1 is the utility model front view.
Fig. 2 is the utility model side view.
Fig. 3 is the utility model vertical view.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described.
As shown in Figure 1, the four-bar linkage centralizer that the utility model relates to, the guide rail of being installed by (1) on base (1), the base (2), be installed on the two securing member v blocks (7) on the guide rail (2), the oil cylinder of fixedlying connected with v block (7) respectively in two ends (8), the central shaft (4) of fixedlying connected with clamp body and form, v block (7) passes through connecting rod (9) and is connected with three orifice plates (3).
The rear portion of two v blocks (7) has riser (6), gripper shoe (5) to connect; Two securing member v blocks (7) are installed on the guide rail (2) and can slide.
As Fig. 1, shown in Figure 3, three orifice plates (3) can rotate around central shaft (4), and connecting rod (9) links together v block (7) and three orifice plates (3), forms hinge.
During work, when oil cylinder shrinks, owing to the rotation of three orifice plates (3), two securing member v blocks (7) can be simultaneously to central slide, and clamping work pieces is realized centering simultaneously.
The above only is a kind of embodiment of the present utility model, is not to be used to limit protection scope of the present invention.
Claims (2)
1, four-bar linkage centralizer, it is characterized in that: its by the guide rail of installing on base, the base, be installed on two securing member v blocks on the guide rail, the oil cylinder of fixedlying connected with v block respectively in two ends, the central shaft of fixedlying connected and form with clamp body, v block is connected with three orifice plates by connecting rod.
2, four-bar linkage centralizer according to claim 1 is characterized in that: the rear portion of above-mentioned two v blocks has riser, gripper shoe to connect.
