Abstract
The invention relates to a fixing fixture, and in particular relates to a spring pressing clamping device. The spring pressing clamping device comprises a base, a pressing rod, a spring, a spring adjusting bolt, a spring cavity, a hinging frame, a hinging arm, a triangular swinging arm and a clamping claw, wherein a pressing rod holder is arranged on the base; the spring cavity is formed by an upper sleeve and a lower sleeve which are matched with each other; the spring is arranged in the spring cavity; the upper part of the spring is fixed on the upper sleeve by the spring adjusting bolt; the lower sleeve is in extruded match with the hinging frame; one end of the hinging arm is blocked into a concave groove in the side edge of the hinging frame while the other end of the hinging arm is hinged to one corner of the triangular swinging arm by a connecting rod; one corner in the middle part of the triangular swinging arm is hinged onto the base while the other corner of the triangular swinging arm is fixedly provided with the clamping claw; and the hinging arm, the connecting rod, the triangular swinging arm and the clamping claw are peripherally and symmetrically arranged into three groups along the hinging frame. The spring pressing clamping device is ingenious and reasonable in arrangement; the degree of force applying of a clamp can be adjusted; and a mode of symmetric clamping is adopted, so that a component can be firmly clamped.
Description
Technical field:
The present invention relates to a kind of stationary fixture, especially a kind of spring presses clamping device.
Background technology:
Anchor clamps and grip device are widely known by the people, and are widely used for manufacturing.Particularly, anchor clamps have various reference surfaces and point, and parts or instrument can accurately be located.In many process, general application anchor clamps are so that these parts can keep correct position relationship in for example punching press, riveted joint, welding, the process of pasting or solidifying.Anchor clamps are considered to requisite parts in the processing industry, and are the vitals of calculating processing cost, also are the vitals that requires in process of production logistics to consider.Most position fixing process all utilize anchor clamps to realize.
The spring that uses now presses clamping device following several shortcoming: 1, the elastic force of spring cannot be regulated, because there is certain difference in the size of workpiece, cause clamping force inadequate, 2, paw is not circumferentially symmetrical so that Workpiece clamping is inharmonious, 3, inconvenient operation so that there is shortcomings in the workpiece that processes, does not reach desirable effect.
Summary of the invention:
The technical problem to be solved in the present invention is: provide a kind of clamping force adjustable, the operation such as conveniently clamp, unclamp and clamp the spring of coordinating and press clamping device.
In order to solve the above problems, the invention provides a kind of spring and press clamping device, comprise pedestal, depression bar, spring, the spring adjusting bolt, spring cavity, body cradle, articulated jib, triangle swing arm and jaw, be provided with the depression bar seat on the described pedestal, described depression bar middle part is hinged on this depression bar seat, and the pressure head of described depression bar is connected to the body cradle below, on the described spring cavity, lower two sleeve mix proportions, described spring is arranged in the spring cavity, spring top is fixed on the upper bush by the spring adjusting bolt, and the extruding of described lower sleeve and body cradle cooperates, and described articulated jib one end is connected in the groove on the body cradle side, the other end is hinged to a jiao of triangle swing arm by connecting rod, one jiao is hinged on the pedestal in the middle part of the triangle swing arm, and another angle of triangle swing arm is fixed with jaw, it is characterized in that: described articulated jib, connecting rod, triangle swing arm and jaw circumferentially are symmetrically arranged with three groups along body cradle.
The spring of use technical solution of the present invention presses clamping device following benefit: 1, because the spring spring is arranged in the spring cavity, spring top is fixed on the upper bush by the spring adjusting bolt, use this structure can make things convenient for the elastic force of regulating spring, clamping with the workpiece that satisfies different materials, 2, be provided with the depression bar seat on the pedestal, the pressure head of described depression bar and body cradle bottom offset, in the time of need to unclamping, can easierly press spring cavity of resorption shell, 3, described articulated jib, connecting rod, triangle swing arm and jaw circumferentially are symmetrically arranged with three groups along body cradle, can allow the clamping work pieces application of force more evenly reach and clamp the purpose of coordinating.
As preferred version, for so that depression bar is preserved balance, be provided with spring between described depression bar and the pedestal.
As preferred version, damage for fear of body cradle, be arranged with three carrying bolts that support body cradle on the described pedestal.
Description of drawings:
Fig. 1 is the structural representation that the present embodiment spring presses clamping device.
The specific embodiment:
Below in conjunction with drawings and Examples technical solution of the present invention is further specified:
As shown in Figure 1: a kind of spring presses clamping device, comprise pedestal 8, depression bar 9, spring 3, spring adjusting bolt 1, spring cavity 2, body cradle 5, articulated jib 10, triangle swing arm 11 and jaw 12 are provided with depression bar seat 13 on the pedestal 8, depression bar 9 middle parts are hinged on the depression bar seat 13, the pressure head of depression bar 9 is connected to body cradle 5 belows, spring cavity 2 is by upper, lower two sleeve mix proportions, spring 3 is arranged in the spring cavity 2, and spring 3 tops are fixed on the upper bush by spring adjusting bolt 1, described lower sleeve cooperates with body cradle 5 extruding, articulated jib 10 1 ends are connected in the groove on body cradle 5 sides, and the other end is hinged to a jiao of triangle swing arm 10 by connecting rod, and one jiao at triangle swing arm 10 middle parts are hinged on the pedestal 8, another angle of triangle swing arm 11 is fixed with jaw 12, articulated jib 10, connecting rod, triangle swing arm 11 and jaw 12 circumferentially are symmetrically arranged with three groups along body cradle 5.
When using spring of the present invention to press clamping device, lever up body cradle 5 by depression bar 9, allow jaw 12 unclamp, put into the workpiece that needs clamping, unclamp depression bar 9, spring 3 restoring forces drive articulated jib 10 rotations, thereby jaw 12 clamp so that triangle rocker arm 11 rotates so that body cradle 5 descends.
For so that depression bar 9 is preserved balance, be provided with returning spring 7 between depression bar 9 and the pedestal 8, damage for fear of body cradle 5, be provided with circumferential three carrying bolts 6 that are used for withstanding body cradle between the bottom of body cradle 5 and the pedestal 8.
Above-described only is preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
