在电子产品的生产过程中，一般会利用电动螺丝刀对螺丝进行固定。固定螺丝工艺要求电动螺丝刀垂直于锁附面，保持螺丝垂直锁附，避免螺丝滑牙或断裂。
现有的锁螺丝工艺操作方法都是由操作工手握电动螺丝刀中部，调整手腕的垂直度，用手感去保持电动螺丝刀垂直，不能保证每次都是垂直锁附，容易导致螺丝打滑牙或断裂，并且作业一致性难以持久保持，产品品质难保证。同时，操作工作业疲劳强度高。
申请内容
本申请提供一种固定工装，能够保证作业的一致性，确保电子产品的品质，同时降低操作工的作业强度。
本申请提供一种固定工装，用于固定电动螺丝刀，所述固定工装包括主滑杆、支撑悬臂和活动夹头，所述支撑悬臂与所述主滑杆之间形成活动连接，以使得所述支撑悬臂能够相对于所述主滑杆作水平方向和竖直方向上的自由移动，所述支撑悬臂设有所述活动夹头，以用于固定所述电动螺丝刀并能够将所述电动螺丝刀限定为竖直方向。
其中，还包括套设在所述主滑杆上的弹簧固定件和弹簧，所述弹簧固定件固定在所述主滑杆上，所述弹簧的一端固定到所述弹簧固定件上，所述弹簧的另一端与所述支撑悬臂相连，以使得所述支撑悬臂在竖直方向上弹性连接至弹簧固定件上。
其中，所述弹簧固定件为中空圆柱体，因而所述弹簧固定件能够套设在所述主滑杆上，所述中空圆柱体的侧面上设有径向延伸的螺纹孔，所述弹簧固定件通过与所述螺纹孔配合的螺钉固定在所述主滑杆上。
其中，还包括轴承连接件和套设在所述主滑杆上的轴承，所述轴承连接件套设在所述主滑杆的外围，所述轴承的外壁与所述轴承连接件固定连接，所述轴承的内壁与所述主滑杆间隙配合，所述支撑悬臂包括相对设置的第一端部和第二端部，所述第一端部与所述活动夹头相连，所述第二端部与所述轴承连接件相连。
其中，所述支撑悬臂包括第一悬臂、第二悬臂和第三悬臂，所述第一悬臂包括相对设置的第三端部和第四端部，所述第二悬臂包括相对设置的第五端部和第六端部，所述第三悬臂包括相对设置的第七端部和第八端部，所述第一悬臂的所述第三端部与所述轴承连接件相连，所述第一悬臂的所述第四端部与所述第二悬臂的所述第五端部形成活动连接，所述第二悬臂的所述第六端部与所述第三悬臂的所述第七端部形成活动连接，所述活动夹头设置在所述第三悬臂的所述第八端部。

相较于现有技术，根据本申请的固定工装中，支撑悬臂与主滑杆之间形成活动连接，以使得支撑悬臂能够相对于主滑杆作水平方向和竖直方向上的自由移动，并且支撑悬臂设有活动夹，活动夹头用于固定电动螺丝刀并且将电动螺丝刀限定在竖直方向，因此支撑悬臂和主滑杆的配合能够实现电动螺丝刀的竖直方向和水平方向上的自由移动，因而操作工无需通过手腕来调整电动螺丝刀的垂直度，能够确保作业的一致性，确保电子产品的品质，同时能够降低操作工的劳动强度。
附图说明
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是根据本申请的固定工装的立体示意图；
图2是根据本申请的固定工装的立体分解示意图。
具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
参照图1和图2，示出根据本申请的固定工装，该固定工装用于固定电动螺丝刀，固定工装包括主滑杆1、固定夹2、支撑悬臂3和活动夹头4，其中，主滑杆1通过固定夹2固定到生产线上，具体地，固定夹2的数量为两个，固定夹2包括呈条块状的第一固定部21和第二固定部22拼合而成，第一固定部21和第二固定部22之间通过螺钉连接，第一固定部21设有第一凹槽211，第二固定部22设有第二凹槽221，第一凹槽211和第二凹槽221均呈半圆形，并且第一凹槽211和第二凹槽221的半径等于主滑杆1的半径，因此当第一固定部21和第二固定部22通过螺钉连接时，第一凹槽211和第二凹槽221能够形成允许主滑杆1通过的孔洞，从而能够固定主滑杆1。支撑悬臂3的第一端部与活动夹头4相连，支撑悬臂3的第二端部与轴承连接件5相连，从而与主滑杆1形成活动连接，该活动夹头4用于固定电动螺丝刀并将电动螺丝刀限定为竖直方向，因此，在工作时，电动螺丝刀可以在有效工作范围内进行上下和水平方向上的自由移动，从而能够移动到螺丝位置，并正对螺丝进行锁附，因而操作工无需通过手腕来调整电动螺丝刀的垂直度，能够确保作业的一致性，确保电子产品的品质，同时能够降低操作工的劳动强度。
当然，固定夹2可以为其他形式的固定结构，例如夹钳形式等。
进一步地，该支撑悬臂3包括第一悬臂31、第二悬臂32和第三悬臂33， 第一悬臂31包括相对设置的第三端部311和第四端部312，第二悬臂32包括相对设置的第五端部321和第六端部322，第三悬臂33包括相对设置的第七端部331和第八端部332，第一悬臂31的第三端部311与轴承连接件5通过螺钉连接，当无需用到固定工装时，可以通过将第一悬臂31从轴承连接件5上拆下，便于拆卸。轴承连接件5设有第一通孔51，第一通孔51的直径大于主滑杆1的直径，轴承连接件5通过第一通孔51套设在主滑杆1上，轴承连接件5能够相对于主滑杆1作轴向运动，从而第一悬臂31与主滑杆1之间形成活动连接。第一悬臂31的第四端部312与第二悬臂32的第五端部321通过销钉形成活动连接，而第二悬臂32的第六端部322与第三悬臂33的第七端部331通过销钉形成活动连接，第三悬臂33的第八端部332与活动夹头4相连，该活动夹头4用于固定电动螺丝刀并将电动螺丝刀限定为竖直方向。
当然，支撑悬臂3的第一悬臂31的第三端部311还可以设有通孔，支撑悬臂3通过该通孔与主滑杆1形成活动连接，因此，轴承连接件5可以省略。
此外，根据本申请的固定工装还包括弹簧6，弹簧6的一端通过点焊与弹簧固定件7固定连接，而弹簧6的另一端通过点焊与轴承连接件5固定连接，其中，弹簧固定件7上设有第二通孔71，该第二通孔71的直径亦与主滑杆1的直径相适应，因而弹簧固定件7通过第二通孔71套设在主滑杆1上，并且弹簧固定件7的侧边设有螺纹孔，弹簧固定件7通过螺钉72与该螺纹孔的配合固定至主滑杆1上，弹簧固定件7的位置可调，具体地，弹簧固定件7的位置能够根据电动螺丝刀的有效工作范围进行调整。轴承8套设在主滑杆1上，轴承8的上端面81与轴承连接件5的下端面52贴合，并且轴承8的外壁通过螺钉与轴承连接件7形成固定连接，轴承8的内壁与主滑杆1形成间隙配合，轴承8进一步限定支撑悬臂3的运动，并且当支撑悬臂3和电动螺丝刀作水平方向的运动时，轴承8能减小运动的摩擦力，便于支撑悬臂3和电动螺丝刀的水平运动。支撑悬臂3能够悬挂在弹簧6上，在工作时，支撑悬臂3的部分重量能够由弹簧6承担，并且由于弹簧6的弹性，支撑悬臂3能够在有效工作范围内于竖直方向上自由运动，在确保产品一致性的同时，进一步能够减轻操作工的劳动强度。
优选地，第三悬臂33的长度小于第一悬臂31或第二悬臂32的长度，因 此，在工作时，如果想小范围移动电动螺丝刀，可以相对于第二悬臂32转动第三悬臂33即可，便于操作。
优选地，主滑杆1由不锈钢制成，不锈钢材质有利于提高主滑杆1的使用寿命。
以上所揭露的仅为本申请较佳实施例而已，当然不能以此来限定本申请之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本申请权利要求所作的等同变化，仍属于申请所涵盖的范围。
