The invention provides a lathe positioning backrest, including a chuck, a fastening ring, screws, nuts and nuts. The chuck is a cylindrical hollow structure, and a fastening ring is installed in the clamp, the fastening ring is cylindrical hollow and the inner wall has internal thread, and the outer wall of the screw is provided with an external thread and the screw is inserted with the screw. The nut is sheathed on the screw and is attached to the end part of the chuck, and the screw end is matched with a nut. The invention can be adjusted by adjusting the screw rotation length and fastening with the nut, which can meet the requirements of different products' size processing. The screws replace the positioning of the mount and the chuck as a whole. The chuck is relatively stationary in the process of rotation and the backrest is relatively stationary. The backrest becomes shorter and the hardness increases, which improves the stability and wear resistance of the positioning backrest and ensures the stability of the length and size of the parts during the process of processing. The disqualification of workpiece during processing is eliminated, and the pass rate reaches 100%.
【技术实现步骤摘要】
一种车床定位靠山
本专利技术涉及一种车床定位靠山。
技术介绍
我公司机加班现有一台手扳车床,每月要完成近二万件小轴的加工,现有的方案都是采用圆柱状的长杆靠山从设备的尾部塞入,贯穿设备的主轴箱,在设备的尾部将定位靠山紧固;前端悬持在夹头的孔里,它越长,震颤问题越严重。在加工过程中长杆式定位靠山长600MM,在使用中随着主轴旋转时抖动严重、耐磨性差,影响设备在加工零件长度尺寸的稳定性造成月均废品率在7%左右。
技术实现思路
本专利技术提出一种车床定位靠山,通过靠山定位降低主轴旋转时抖动严重,提高耐磨性,从而降低废品率,提高生产效率。本专利技术的技术方案是这样实现的:一种车床定位靠山,包括夹头、紧固衬圈、螺钉、螺母和螺帽,所述夹头为圆柱形中空结构,所述夹头内安装紧固衬圈,所述紧固衬圈为圆柱形中空形且内壁设有内螺纹,所述螺钉外壁设有外螺纹且螺钉配合插入紧固衬圈中;所述螺母套装于所述螺钉上且贴合夹头端部,所述螺钉端部配合装有螺帽。优选地,所述夹头内过盈配合安装紧固衬圈。优选地,所述螺钉旋入紧固衬圈内的长度根据实际产品的尺寸调节。本专利技术产生的有益效果为:本专利技术可以通过调节螺钉的旋入长度,再用螺帽紧固,可适应不同产品的尺寸加工要求。螺钉替代定位靠山且和夹头连为一体,夹头在旋转的过程中和靠山是相对静止的,靠山变短、硬度增加,提高了定位靠山的稳定性和耐磨度,保证了设备在加工过程中零件长度尺寸的稳定性。消除了工件在加工时产生的不合格,合格率达到100%。附图说明为了更清楚地说明本专利技术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 ...
