Description

对敲式反作用力臂机构Counter-knock type reaction arm mechanism 技术领域Technical field
本发明涉及紧固设备技术领域,特别是涉及一种对敲式反作用力臂机构。The present invention relates to the technical field of fastening devices, in particular to a counter-knock type reaction force arm mechanism.
背景技术Background technique
螺栓、螺母配合用于零件之间的紧固连接,员工在进行装配紧固作业时,首先使用风扳进行预紧,之后需要配合使用扳手手动卡紧,以防止螺栓和螺母之间在紧固时由于反作用力的存在而发生共转,在此过程中因为是手动卡紧扳手,员工无法确保做到不产生共转而完全锁止,因此在紧固作业后仍需要进行扭力测试以保证工件锁止到位要求,但是在扭力测试工程中同样也要防止共转,并且需要两人配合才能进行,导致耗时长,作业效率低下,成本较高,而且,操作员工使用风扳,左右手受到的震动力较大,同时扭力岗位员工为了保证工件力矩,所要扭动的圈数多,在大力矩的情况下,其劳动强度较大。Bolts and nuts are used to fasten the connection between the parts. When the employees perform the assembly and tightening operations, they first use the air wrench to pre-tighten, and then need to use the wrench to manually tighten it to prevent the bolts and nuts from being tightened. Co-rotation occurs due to the presence of the reaction force during this process. During this process, because the wrench is manually clamped, employees cannot ensure that the wrench will not be co-rotated and fully locked. Therefore, a torque test is still required to ensure the workpiece after the tightening operation. Locking in place is required, but in the torsion test project, co-rotation should also be prevented, and two people are required to cooperate. This results in time-consuming, low work efficiency and high cost. Moreover, when the operator uses a wind wrench, left and right hands are shaken. At the same time, in order to ensure the torque of the workpiece, employees in the torque position have to twist a large number of turns. In the case of high torque, the labor intensity is greater.

请参见图1,示意性地示出了本发明的对敲式反作用力臂机构,其包括横梁10、力臂杆20以及工具夹持装置30,力臂杆20安装于所述横梁10上并可沿横梁10的长度方向平移,工具夹持装置30固定连接于所述横梁10的一端,且该工具夹持装置30用于固定电动工具100。其中,力臂杆20与横梁10之间连接有处于拉伸状态的弹性件40,力臂杆20的底端连接有用于套接螺母或螺栓的固定套筒21,使用时,将电动工具100安装于工具夹持装置30上,并且在电动工具100的动力输出端101套接上拧紧套筒102,拧紧套筒102的外端用于套接螺栓或螺母,此时,更重要的是,固定套筒21与套接于电动工具动力输出端101上的拧紧套筒102相正对。Please refer to FIG. 1, which schematically shows the knock-on reaction force arm mechanism of the present invention, which includes a beam 10, a moment arm rod 20, and a tool holding device 30. The moment arm rod 20 is mounted on the beam 10 and It can be translated along the length direction of the cross beam 10, the tool clamping device 30 is fixedly connected to one end of the cross beam 10, and the tool clamping device 30 is used for fixing the electric tool 100. Wherein, between the moment arm rod 20 and the cross beam 10 is connected an elastic member 40 in a stretched state, and the bottom end of the moment arm rod 20 is connected with a fixing sleeve 21 for socketing nuts or bolts. When in use, the power tool 100 Installed on the tool clamping device 30, and sleeved a tightening sleeve 102 on the power output end 101 of the electric tool 100, and the outer end of the tightening sleeve 102 is used to sleeve bolts or nuts. At this time, more importantly, The fixing sleeve 21 is directly opposite to the tightening sleeve 102 sleeved on the power output end 101 of the electric tool.
基于上述技术特征的对敲式反作用力臂机构,通过在力臂杆20的底端设置固定套筒21,用于套接需要锁紧的螺母或者螺栓,并且通过工具夹持装置30固定电动工具100,使得固定套筒21与电动工具100的动力输出端101相正对,即使套接于电动工具动力输出端101的拧紧套筒102与该固定套筒21相对设置,拧紧套筒102的外端用于套接螺栓或者螺母,在进入螺栓螺母的紧固工序时,操作人员通过克服弹性件40的弹力,远离工具夹持装置30的方向沿着横梁10拉动力臂杆20,使力臂杆20与电动工具100分开一段距离,以确保固定套筒21与拧紧套筒102之间具有将螺接在一起的螺栓与螺母能放置进入的空间,随后将电动工具动力输出端101上的拧紧套筒102和固定套筒21从两端分别套入对应的螺栓/螺母(或者是螺母/螺栓),套接完成后,放开力臂杆20,在弹性件40弹力的作用下使拧紧套筒102和固定套筒21压紧螺栓、螺母不松开,这种左右打开的夹紧方式,便捷高效,且由弹性件40保证拉紧,使紧固时不松开。由于电动工具100和力臂杆20的位置相对是固定的,力臂杆20的一端作固力臂,工具夹持装置30的一端与电动工具100固定作紧固力臂用,因此操作人员在后续启动电动工具100开始进行预紧或者紧固作业后,螺栓螺母之间由于共转趋势产生的反作用力直接就由电动工具100和力臂杆20组成的反作用力臂机构抵消,由此能够确保螺栓和螺母不会发生共转,使紧固力矩满足设定值要求,从而削减了对应扭力工程,有利于提高工作效率,同时能降低劳动强度。优选地,为增大套筒的扭力紧固效果,固定套筒21和拧紧套筒102的内部均设为内十二角。The counter-knocking reaction force arm mechanism based on the above technical features is provided with a fixing sleeve 21 at the bottom end of the force arm rod 20 for socketing nuts or bolts that need to be locked, and the power tool is fixed by the tool clamping device 30 100, so that the fixed sleeve 21 is directly opposite to the power output end 101 of the electric tool 100, even if the tightening sleeve 102 sleeved on the power output end 101 of the electric tool is opposite to the fixed sleeve 21, the outer side of the sleeve 102 is tightened. The end is used to socket bolts or nuts. When entering the tightening process of bolts and nuts, the operator overcomes the elastic force of the elastic member 40 and pulls the power arm rod 20 along the beam 10 in the direction away from the tool clamping device 30 to make the force arm The rod 20 is separated from the power tool 100 by a certain distance to ensure that there is a space between the fixing sleeve 21 and the tightening sleeve 102 where the bolts and nuts that are screwed together can be placed, and then the power output end 101 of the power tool is tightened The sleeve 102 and the fixed sleeve 21 are respectively sleeved with corresponding bolts/nuts (or nuts/bolts) from both ends. After the sleeve is completed, the lever 20 is released, and the sleeve is tightened under the action of the elastic force of the elastic member 40. The cylinder 102 and the fixed sleeve 21 compress the bolts and nuts without loosening. This clamping method of left and right opening is convenient and efficient, and the elastic member 40 ensures the tension, so that the tightening is not loosened. Since the positions of the electric tool 100 and the moment arm rod 20 are relatively fixed, one end of the moment arm rod 20 is used as a fixed force arm, and one end of the tool clamping device 30 is fixed with the electric tool 100 as a tightening force arm. Therefore, the operator After the power tool 100 is subsequently started for pre-tightening or tightening operations, the reaction force between the bolts and nuts due to the co-rotation trend is directly offset by the reaction force arm mechanism composed of the power tool 100 and the force arm rod 20, thereby ensuring The bolts and nuts will not rotate together, so that the tightening torque meets the set value requirements, thereby reducing the corresponding torsion engineering, which is beneficial to improve work efficiency and reduce labor intensity. Preferably, in order to increase the torque tightening effect of the sleeve, the insides of the fixing sleeve 21 and the tightening sleeve 102 are both set to inner twelve corners.

In this way, the electric tool 100 and the moment arm rod 20 are arranged in a cross manner, which can increase the operating angle of view, and is ergonomic, which is convenient for the operator to perform the bolt or nut The nested pre-alignment improves production efficiency; moreover, the cross-arrangement form is more conducive to counteracting the reaction force, and it mimics the form of using a wrench to clamp to prevent co-rotation.
