The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.
如图1所示，本实用新型是一种侧向推靠式夹紧机构，包括侧推缸座1和侧推杆5，该侧推杆5位于侧推缸座1的侧面。As shown in FIG. 1 , the utility model is a side-push type clamping mechanism, which includes a side-push cylinder base 1 and a side push rod 5 . The side push rod 5 is located on the side of the side-push cylinder base 1 .
其中，上述的侧推缸座1的靠近侧推杆5的侧壁设置有自上至下依次分布的上孔洞(未在图中标出)、轴销6以及下孔洞(未在图中标出)，并且上述侧推杆5的中部通过该轴销6进行固定，从而使得侧推杆5以轴销6为支点实现杠杆式结构，即侧推杆5的顶部和底部可以围绕轴销6做一定角度的旋转运动。Wherein, the sidewall of the above-mentioned side thrust cylinder block 1 close to the side push rod 5 is provided with an upper hole (not marked in the figure), a shaft pin 6 and a lower hole (not marked in the figure) distributed sequentially from top to bottom. , and the middle part of the above-mentioned side push rod 5 is fixed by the pivot pin 6, so that the side push rod 5 takes the pivot pin 6 as a fulcrum to realize a lever structure, that is, the top and bottom of the side push rod 5 can be fixed around the pivot pin 6 Angle of rotational movement.
同时，为了强化侧推杆5的往复运动，在侧推缸座1内部的顶部设置有压缩弹簧2和顶销3，该顶销3的一端与压缩弹簧2相连，另一端为光滑的球形端且穿过上孔洞与侧推杆5的顶部相接触，以便利用压缩弹簧2的弹力使侧推杆5恢复初始状态。At the same time, in order to strengthen the reciprocating movement of the side push rod 5, a compression spring 2 and a push pin 3 are arranged on the top of the side push cylinder seat 1, one end of the push pin 3 is connected with the compression spring 2, and the other end is a smooth spherical end And contact with the top of the side push rod 5 through the upper hole, so that the side push rod 5 can be restored to its original state by the elastic force of the compression spring 2 .
优选的，为了提高顶销3运动的稳定性，在顶销3上设置有紧固螺钉4，且在侧推缸座1的表面还设置有条形孔洞(未在图中标出)，并通过将紧固螺钉4的一端固定于顶销3上，而另一端穿过条形孔洞，使得当顶销3运动时，紧固螺钉4仅仅在条形孔洞内滑动，如此便可以达到提高机构稳定性的效果。Preferably, in order to improve the stability of the movement of the ejector pin 3, a fastening screw 4 is provided on the ejector pin 3, and a bar-shaped hole (not marked in the figure) is also provided on the surface of the side thrust cylinder block 1, and through One end of the fastening screw 4 is fixed on the top pin 3, and the other end passes through the strip-shaped hole, so that when the top pin 3 moves, the fastening screw 4 only slides in the strip-shaped hole, so that the stability of the mechanism can be improved sexual effect.
此外，上述的侧推缸座1内部的底部还设置有直线缸7，该直线缸7的一端穿过下孔洞与侧推杆5的底部相接触，以便为侧推杆5的运动提供动力。In addition, a linear cylinder 7 is provided at the bottom of the above-mentioned side thrust cylinder base 1 , and one end of the linear cylinder 7 contacts the bottom of the side push rod 5 through the lower hole, so as to provide power for the movement of the side push rod 5 .

本实用新型中侧向推靠式夹紧机构的工作原理为：当直线缸7工作时，其伸长运动会推动侧推杆5，使得侧推杆5可以围绕轴销6做一定角度的旋转运动；此时侧推杆5的顶部会对顶销3施加压力，并逐渐靠近侧推缸座1的侧壁，从而夹紧工作；The working principle of the lateral pushing type clamping mechanism in the utility model is: when the linear cylinder 7 is working, its elongation motion will push the side push rod 5, so that the side push rod 5 can rotate around the shaft pin 6 at a certain angle ; At this time, the top of the side push rod 5 will exert pressure on the ejector pin 3, and gradually approach the side wall of the side push cylinder block 1, thereby clamping work;
当直线缸7停止工作时，由于顶销3一端的压缩弹簧2的弹力作用，使得顶销3对其另一端的侧推杆5产生一定的推力，并将侧推杆5推回至初始状态，并等待下一次夹紧操作。When the linear cylinder 7 stops working, due to the elastic force of the compression spring 2 at one end of the top pin 3, the top pin 3 generates a certain thrust on the side push rod 5 at the other end, and pushes the side push rod 5 back to the initial state , and wait for the next clamping operation.
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model.
