Abstract

The utility model discloses a single-cylinder two-rocker-arm clamping mechanism, which comprises a support, and a first clamping arm and a second clamping arm, which are arranged on the support in a rotating way as well as a drive air cylinder with a piston rod being hinged with the first clamping arm and a cylinder body being hinged with the second clamping arm, wherein the first clamping arm and the second clamping arm form a jaw structure, and the support is also provided with an upper limiting block and a lower limiting block, which respectively correspond to the first clamping arm and the second clamping arm. The two clamping arms are controlled to move through one air cylinder, so that a large openness can be realized, the single-cylinder two-rocker-arm clamping mechanism is suitable for clamping different specially-shaped parts, the action amplitude and precision of the clamping arms can be improved by utilizing the upper limiting block and the lower limiting block, and the adaptability of the clamping device can be improved through the adjustable design of the upper limiting block and the lower limiting block.

Description

The two rocking arm clamp mechanism of single cylinder

Technical field

The utility model relates to field of mechanical technique, particularly relates to the two rocking arm clamp mechanism of a kind of single cylinder.

Background technology

Automobile component needs to process before dispatching from the factory, the detection of assembling and Performance Detection or machining accuracy, automobile component need to be fixed on checkout gear when processing or detection, a lot of characteristic faces are arranged on automobile component, and the locating surface corresponding with the characteristic face position on automobile component to be detected arranged also on checkout gear, after parts to be assembled or detection automobile component are in place, need to utilize clamp mechanism to clamp and namely fix automobile component to be detected.

In prior art, clamp mechanism generally comprises support, is fixed on the driving cylinder on this support, be fixedly mounted on the first jaw on this support, by rotating shaft and the hinged clamp arm of this support, this clamp arm one end is provided with the second jaw that matches with described the first jaw, and the other end is connected with the piston rod of described driving cylinder.When driving the piston rod movement of cylinder, drive clamp arm and rotate around the shaft, make the second jaw open or clamp with respect to the first jaw.

Compress if be difficult to insert or be difficult to but jaw of some form parts is fixing, need auxiliary fixture, cause larger inconvenience to detection.

Summary of the invention

The purpose of this utility model is for the technological deficiency that exists in prior art, and provides a kind of single cylinder easy to use simple in structure two rocking arm clamp mechanism.

For realizing that the technical scheme that the purpose of this utility model adopts is:

The two rocking arm clamp mechanism of a kind of single cylinder, comprise support, can be rotatably set in the first clamp arm and the second clamp arm on support, and piston rod and the first clamp arm is hinged, cylinder body and the hinged driving cylinder of the second clamp arm, wherein, described the first clamp arm and the second clamp arm consist of jaw structure, also are provided with corresponding with described the first clamp arm and the second clamp arm respectively upper limit and lower limit on described support.

Described the first clamp arm and the second clamp arm be hinged being arranged on support coaxially.

Described upper limit position block, lower position block position, length is adjustable.

Compared with prior art, the beneficial effects of the utility model are:

The utility model utilizes a cylinder to control two clamp arm actions, can realize larger opening, be applicable to the clamp operation of various profiled parts, utilize the up and down limited block can improve movement range and the precision of clamp arm, with the adjustable design of up and down limited block, increased the applicability of this clamping device simultaneously.

Description of drawings

Figure 1 shows that the two rocking arm clamp mechanism perspective view of single cylinder of the present utility model;

Figure 2 shows that side-looking structural representation shown in Figure 1.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

As illustrated in fig. 1 and 2, the two rocking arm clamp mechanism of single cylinder of the present utility model, comprise support 1, can be rotatably set in the first clamp arm 2 and the second clamp arm 3 on support, and piston rod and the first clamp arm 2 is hinged, cylinder body and the hinged driving cylinder 4 of the second clamp arm 3, wherein, described the first clamp arm and the second clamp arm consist of jaw structure, also are provided with corresponding with described the first clamp arm and the second clamp arm respectively upper limit and lower limit on described support.

Specifically, described the first clamp arm and piston rod end are hinged by rotating shaft, the axle ear of described the second clamp arm and cylinder body is hinged by rotating shaft, and the articulated position of the second clamp arm and cylinder body is positioned at cylinder body and closes on tailpiece of the piston rod, to guarantee that cylinder piston rod stretches out smoothly or retracts.

Wherein, described the first clamp arm and the second clamp arm are hinged by rotating shaft and support upper end, the visual parts to be clamped of the shape of described the first clamp arm and the second clamp arm arrange arbitrarily, simultaneously, upper end at clamp arm also can be bolted to connection various fixture blocks, utilizes fixture block further to improve this clamping device to the adaptability of form parts.

As preferred version, described the first clamp arm and the second clamp arm be hinged being arranged on support coaxially, both coaxial settings, and namely the first clamp arm and the second clamp arm rotate around same rotating shaft, make control more stable, clamp effect and further improve.

Described upper and lower spacing rotating shaft above and below that is separately positioned on clamp arm, and respectively with corresponding clamp arm relative set, its locations of structures, length is adjustable, wherein, adjustable mode has a variety of, as above lower position block can adopt the cooperation of bolt and slotted hole to realize that its position is adjustable, realizes that by the piece that holds of different sizes its length is adjustable, specifically no longer describes.

In use, at first cylinder is in the piston rod retracted mode.This moment, two clamping limbs were located by lower limit respectively, after the first clamping limb and the second clamping limb are clamped in the precalculated position, piston rod is stretched out, distance between piston rod end and cylinder body increases, drive that two clamping limbs rotate until spacing by upper limit position block and parts to be held are clamped respectively, after action was completed, piston rod was retracted and is indicated two clamping limbs again spacing by lower position block respectively.

The above is only preferred embodiment of the present utility model; should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
