Description

一种带自动焊接的汽车传动轴校直机 技术领域
本实用新型涉及一种传动轴校直机，特别涉及一种带自动焊接的汽车传动轴校直机。
背景技术
汽车传动轴在进行后续加工时一般需要进行检测校直处理，以保证传动轴生产使用的精确性与稳定性。但常规传动轴的校直加工一般采用机床上的夹缸对传动轴进行夹持固定，而后通过使用者手工对传动轴进行冲压、锤击等校直处理，这种校直方式不仅增加了生产者对传动轴校直加工的困难性与复杂程度，也无法有效的保证传动轴校直的精确度，极大的影响了后续传动轴加工的产品生产精度与质量。
基于上述问题，我司研发并在先申请了专利号为CN201910832217.1的一种传动轴校直机、以及专利号为CN201910923034.0的一种带缓冲及微顶紧的传动轴校直机，以解决上述问题。
现有的传动轴由前万向节叉、中间体以及后万向节叉组成，且中间体的两端在分别与前万向节叉、后万向节叉装配时需进行焊接。但是，上述校直机均不具备自动焊接功能，使得焊接与校直要在两台不同的装置上完成，进而降低工作效率，因而有待改进。
发明内容
本实用新型的目的是提供一种带自动焊接的汽车传动轴校直机，这种校直机兼具有校直与焊接的功能，使得在一台装置上即可完成两道工序，以提高工作效率。
本实用新型的上述技术目的是通过以下技术方案得以实现的：一种带自动 焊接的汽车传动轴校直机，包括有机架、工作台、主轴头A、主轴头B以及用于监测传动轴圆周跳动的检测机构，所述工作台的上方设置有焊接机构，所述机架上设置有可对焊接机构的空间位置进行调整的驱动机构；在所述驱动机构的作用下，所述焊接机构对汽车传动轴待焊部位进行焊接。
本实用新型的进一步设置为：所述焊接机构为两个，且分别对应于传动轴两端的待焊接部位。
本实用新型的进一步设置为：所述驱动机构包括垂直滑轨以及与垂直滑轨滑动连接的第一滑块，所述垂直滑轨的一端设置有可驱动第一滑块在垂直滑轨上移动的第一驱动件，所述第一滑块的一侧与焊接机构固定连接。

本实用新型的进一步设置为：所述工作台上设置有两段独立的导轨，每段所述导轨均滑动连接有移动板，两个所述移动板分别对主轴头A以及主轴头B进行支撑，每段所述导轨的一端均设置有可驱动移动板进行移动的第三驱动件，两个所述移动板均穿设有同一个用以保护导轨的遮挡件。
本实用新型的进一步设置为：每段所述导轨均由两个相互平行的驱动滑轨组成，每个所述驱动滑轨上均滑动连接有活动块，两个所述活动块的上端面与同一个移动板固定连接，每个所述活动块朝向另一活动块的一侧均设置有可与遮挡件相配合的置物槽。
本实用新型的进一步设置为：所述遮挡件包括有具有凹槽的固定板，所述固定板的两端设置有可与置物槽相配合的折边。
本实用新型的进一步设置为：两个所述移动板上均套设有用以分别保护主轴头A以及主轴头B的保护罩。
本实用新型的进一步设置为：所述检测机构包括与主轴头相连的测架，所述测架的一侧铰接有转动杆，所述转动杆的一端设置有位于传动轴上方的压杆，所述转动轴的另一端与抵接有检测器，所述测架的顶部设置有用以固定检测器的顶板，所述顶板上还设置有挡板，所述挡板与转动杆之间设置有弹簧；在所述弹簧的作用下，位于所述转动板一端压杆与传动轴表面相接触，位于所述传动板的另一端与检测器相接触。
本实用新型的进一步设置为：所述工作台上设置有用以保护检测机构的保护壳，所述保护壳上开设有可供压杆穿出的通槽。
综上所述，本实用新型具有以下有益效果：本申请通过驱动机构调整焊接机构的空间位置，使得焊接机构对汽车传动轴待焊部位进行焊接。由于传动轴在主轴头A的作用下在工作台上发生转动，此时焊接机构与传动轴进行相对转动，进而焊接机构可实现对传动轴的周向焊接。

具体实施方式
以下结合附图对本实用新型作进一步详细说明。
如图1-图7所示，一种带自动焊接的汽车传动轴校直机，包括有机架1、工作台2、主轴头A3、主轴头B4以及用于监测传动轴圆周跳动的检测机构5，主轴头A3与主轴头B4分别将汽车传动轴两端进行固定。
工作台2的上方设置有焊接机构6，机架1上设置有可对焊接机构6的空间位置进行调整的驱动机构7。在驱动机构7的作用下，焊接机构6对汽车传动轴待焊部位进行焊接。
在具体使用时，先将传动轴放置于机架1上，并通过主轴头A3与主轴头B4分别将汽车传动轴两端进行固定，此外主轴头A3还可以带动传动轴进行转动，其校直机的具体工作过程可参阅我司在先申请的专利。
驱动机构7通过调整焊接机构6的空间位置，使得焊接机构6对汽车传动轴待焊部位进行焊接。由于传动轴在主轴头A3的作用下在工作台2上发生转动，此时焊接机构6与传动轴进行相对转动，进而焊接机构6可实现对传动轴的周向焊接。
进一步的，焊接机构6优选为两个，且分别对应于传动轴两端的待焊接部位。
进一步的，驱动机构7包括垂直滑轨8以及与垂直滑轨8滑动连接的第一 滑块9，垂直滑轨8的一端设置有可驱动第一滑块9在垂直滑轨8上移动的第一驱动件10。该第一滑块9的一侧与焊接机构6固定连接。
通过第一驱动件10可调整焊接机构6在垂直方向上的高度，当工作台2上未放置有传动轴，则第一驱动件10驱动焊接机构6向上移动，使得焊接机构6与工作台2之间的间距拉大，以便于传动轴放置于工作台2上；当工作台2上放置有传动轴时，第一驱动件10控制焊接机构6下移，从而实现对传动轴的焊接。需特别说明的是：本申请所述的垂直，是指垂直于工作台2的方向。
进一步的，驱动机构7还包括有与机架1相连接的水平滑轨11，水平滑轨11上滑动连接有第二滑块12，第二滑块12的一侧与垂直滑轨8固定连接，水平滑轨11的一端设置有可驱动第二滑块12在水平滑轨11上移动的第二驱动件13。
通过第二驱动件13的作用下，可调整垂直滑轨8的在水平方向上的移动，进而调整焊接机构6在水平方向上的移动。由于传动轴的规格长度不一，在针对不同传动轴进行焊接时需先调整焊接机构6的水平位置。需特别说明的是：本申请所述的水平，是指沿工作台2长度方向水平设置。
进一步的，工作台2上设置有两段独立的导轨14，每段导轨14均滑动连接有移动板15，两个移动板15分别对主轴头A3以及主轴头B4进行支撑。每段导轨14的一端均设置有可驱动移动板15进行移动的第三驱动件(附图未示出)，两个移动板15均穿设有同一个用以保护导轨14的遮挡件16。
通过第三驱动件，调整主轴头A3以及主轴头B4之间的距离，以适应不同长度的传动轴的夹紧。此外，由于焊接过程中会产生火花或其它碎屑，且导轨14是精密导轨14。为避免焊接过程中的火花或碎屑对导轨14造成损坏，因此需要采用遮挡件16进行遮挡。
进一步的，每段导轨14均由两个相互平行的驱动滑轨组成，每个驱动滑轨上均滑动连接有活动块17，两个活动块17的上端面与同一个移动板15固定连接。每个活动块17朝向另一活动块17的一侧均设置有可与遮挡件16相配合的置物槽18。
进一步的，遮挡件16包括有具有凹槽19的固定板，该凹槽19可用于盛放焊接时所产生的琐屑等杂质。固定板的两端设置有可与置物槽18相配合的折边20。
进一步的，两个移动板15上均套设有用以分别保护主轴头A3以及主轴头B4的保护罩21。通过保护罩21，可实现对保护主轴头A3以及主轴头B4的保护。
此外，由于检测机构5中具有检测器25，为避免焊接过程对检测器25造成损坏。本申请还对检测机构5进行改进，具体如下：
进一步的，检测机构5包括与主轴头相连的测架22，测架22的一侧铰接有转动杆23，转动杆23的一端设置有位于传动轴上方的压杆24，转动轴的另一端与抵接有检测器25。使得压杆24能够贴合在传动轴的表面，并通过检测器25对压杆24所接触的传动轴圆周跳动进行检测，便于让生产者通过检测机构5对传动轴的校直精度进行检测。
测架22的顶部设置有用以固定检测器25的顶板26，顶板26上还设置有用以保护检测器25不受焊接影响的挡板27。挡板27与转动杆23之间设置有弹簧28，在弹簧28的作用下，位于转动板一端压杆24与传动轴表面相接触，位于传动板的另一端与检测器25相接触。
通过弹簧28的设置，可有效提高压杆24与传动轴接触后的贴合牢固性，避免压杆24进行跳动，错位的可能，有效提高压杆24所接触传动轴跳动的精确性。此外，挡板27可有效防护检测器25不受焊接影响。
进一步的，工作台2上设置有用以保护检测机构5的保护壳29，保护壳29上开设有可供压杆24穿出的通槽30。
具体实施例仅仅是对本实用新型的解释，其并不是对本实用新型的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本实用新型的权利要求范围内都受到专利法的保护。
