Abstract

The utility model relates to a fixing clamp, in particular to a spring pressing clamping device. The spring pressing clamping device comprises a base, a compression rod, a spring, a spring adjusting bolt, a spring cavity, a hinging frame, a hinging arm, a triangular swinging arm and a clamping jaw. A compression 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 portion of the spring is fixed on the upper sleeve through the spring adjusting bolt. The lower sleeve is matched with the hinging frame in an extruded mode. One end of the hinging arm is clamped into a concave groove in the side edge of the hinging frame and the other end of the hinging arm is hinged to one corner of the triangular swinging arm through a connecting rod. One corner in the middle part of the triangular swinging arm is hinged onto the base and the other corner of the triangular swinging arm is fixedly provided with the clamping jaw. The hinging arm, the connecting rod, the triangular swinging arm and the clamping jaw are peripherally and symmetrically arranged into three groups along the hinging frame. The spring pressing clamping device is ingenious and reasonable in arrangement, clamp force application degrees can be adjusted, and a mode of symmetric clamping enables a workpiece to be firmly clamped.

Description

A kind of spring presses clamping device

Technical field:

The utility model relates to a kind of stationary fixture, and 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 relation 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 logistics to consider in process of production.Most position fixing process all utilize anchor clamps to realize.

The spring that uses presses clamping device now 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 not enough, 2, paw is not circumferentially to be symmetrically distributed to make that the workpiece clamping is inharmonious, 3, inconvenient operation makes the workpiece that processes have many shortcomings, does not reach desirable effect.

The utility model content:

The technical problems to be solved in the utility model is: provide a kind of clamping force adjustable, operation such as conveniently clamp, unclamp and clamp the spring of coordinating and press clamping device.

In order to solve the above problems, the utility model provides a kind of spring to press clamping device, comprise pedestal, depression bar, spring, spring is regulated bolt, spring cavity, body cradle, articulated jib, triangle swing arm and jaw, described pedestal is provided with the depression bar seat, 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, two sleeves cooperate composition down, described spring is arranged in the spring cavity, bolting is regulated to upper bush by spring in spring top, and described lower sleeve pushes with body cradle and 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, triangle swing arm middle part is hinged on the pedestal for one jiao, and fixedly there is jaw at another angle of triangle swing arm, 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 solutions of the utility model presses clamping device following benefit: 1, because the spring spring is arranged in the spring cavity, bolting is regulated to upper bush by spring in spring top, use this structure can make things convenient for the elastic force of regulating spring, clamping with the workpiece that satisfies different materials, 2, pedestal is provided with the depression bar seat, the pressure head of described depression bar and body cradle bottom offset, in the time of need 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, in order to make depression bar preserve 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 solutions of the utility model are further specified:

As shown in Figure 1: a kind of spring presses clamping device, comprise pedestal 8, depression bar 9, spring 3, spring is regulated bolt 1, spring cavity 2, body cradle 5, articulated jib 10, triangle swing arm 11 and jaw 12, pedestal 8 is provided with depression bar seat 13, and 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 last, two sleeves cooperate composition down, and spring 3 is arranged in the spring cavity 2, and spring 3 tops are regulated bolt 1 by spring and are fixed on the upper bush, 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 triangle swing arm 10 middle parts are hinged on the pedestal 8 for one jiao, fixedly there is jaw 12 at another angle of triangle swing arm 11, 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 utility model 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 make body cradle 5 descend, and drive articulated jib 10 rotations, thereby make 11 rotations of triangle rocking arm make jaw 12 clamp.

In order to make depression bar 9 preserve 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 utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
