Description
技术领域 technical field
本发明涉及一种曲轴加工辅助机械，具体地说是一种曲轴轴颈定位夹紧装置。 The invention relates to a crankshaft processing auxiliary machine, in particular to a crankshaft journal positioning and clamping device.
背景技术 Background technique
我们知道，曲轴磨削时需对轴颈进行定位夹紧，若夹紧时的位置不固定，易造成轴颈磨削时圆度不达标的现象，而普通的定位机构，只能靠公差进行定位，夹紧时存在一定误差。采用夹紧力可调节的定位装置可以从根本上解决夹紧位置不固定的问题，排除夹紧时的误差。但迄今为止还未见有夹紧力可调节的曲轴轴颈定位夹紧装置的文献报道。 We know that the journal needs to be positioned and clamped during crankshaft grinding. If the clamping position is not fixed, it is easy to cause the roundness of the journal to fail to meet the standard. However, ordinary positioning mechanisms can only be performed by tolerances. There is a certain error in positioning and clamping. The use of a positioning device with adjustable clamping force can fundamentally solve the problem that the clamping position is not fixed, and eliminate errors during clamping. But so far there is no literature report on a crankshaft journal positioning clamping device with adjustable clamping force.

附图说明 Description of drawings
下面结合附图对本发明作进一步的描述。 The present invention will be further described below in conjunction with the accompanying drawings.
图1是本发明装配状态的结构示意图。 Fig. 1 is a structural schematic diagram of the assembled state of the present invention.
图中的标号是：1.定位块，2.夹紧杆，3.弹簧，4.调节螺母，5.工件。 The labels in the figure are: 1. positioning block, 2. clamping rod, 3. spring, 4. adjusting nut, 5. workpiece.
具体实施方式 detailed description
从图1中可以看出，一种曲轴轴颈定位夹紧装置，其包括定位块1、夹紧杆2、弹簧3、调节螺母4、工件5等。 It can be seen from FIG. 1 that a crankshaft journal positioning and clamping device includes a positioning block 1, a clamping rod 2, a spring 3, an adjusting nut 4, a workpiece 5, and the like.
本发明所述定位块1上部设有一用来放置工件的锥形长槽，便于工件5快速放入。定位块1侧面设有一与锥形长槽相通的圆柱阶梯孔，该圆柱阶梯孔后端部带有内螺纹。所述夹紧杆2为阶梯圆柱结构，其安装在圆柱阶梯孔内，前端与工件5接触，后部圆柱上套有弹簧3。所述弹簧3位于调节螺4母和夹紧杆2上设有的凸台之间。夹紧杆2在圆柱阶梯孔内通过弹簧3来回移动，阶梯圆柱孔起的导向作用。 The upper part of the positioning block 1 of the present invention is provided with a tapered long groove for placing workpieces, which is convenient for the workpieces 5 to be put in quickly. The side of the positioning block 1 is provided with a cylindrical stepped hole communicating with the tapered long groove, and the rear end of the cylindrical stepped hole has an internal thread. The clamping rod 2 is a stepped cylinder, which is installed in the stepped hole of the cylinder, the front end is in contact with the workpiece 5, and the rear cylinder is covered with a spring 3 . The spring 3 is located between the adjusting nut and the boss provided on the clamping rod 2 . The clamping rod 2 moves back and forth in the cylindrical stepped hole through the spring 3, and the stepped cylindrical hole plays a guiding role.
所述调节螺母4设有与定位块1内螺纹配合的外螺纹，转动调节螺母4，调整弹簧3的压缩量，实现夹紧杆2对工件5夹紧力的自动调整，对工件进行夹紧定位。 The adjusting nut 4 is provided with an external thread that cooperates with the internal thread of the positioning block 1, and the adjusting nut 4 is rotated to adjust the compression amount of the spring 3, so as to realize the automatic adjustment of the clamping force of the clamping rod 2 to the workpiece 5, and clamp the workpiece position.
本发明所述夹紧杆2前端为光滑的球头结构。这样，当工件5在重力的作用下落下时，工件5与夹紧杆2前端光滑的球头接触，挤压夹紧杆2后移，压缩弹簧，不妨碍工件的自由放置。自由落下后，压缩的弹3又迫使夹紧杆2对工件5实施定位夹紧。转动调节螺母，调整弹簧的压缩量，进而实现夹紧杆对工件夹紧力的自动调整。夹紧杆后端的圆柱对弹簧起到导向作用。 The front end of the clamping rod 2 in the present invention is a smooth ball head structure. In this way, when the workpiece 5 falls under the action of gravity, the workpiece 5 contacts with the smooth ball head at the front end of the clamping rod 2, and the clamping rod 2 is squeezed to move backward, compressing the spring, without hindering the free placement of the workpiece. After falling freely, the compressed spring 3 forces the clamping rod 2 to perform positioning and clamping on the workpiece 5 again. Turn the adjusting nut to adjust the compression amount of the spring, and then realize the automatic adjustment of the clamping force of the clamping rod to the workpiece. The cylinder at the rear end of the clamping rod guides the spring.
本发明采用上述组成结构，在定位块的一侧设置可移动调整的夹紧杆，对工件进行定位夹紧。其结构简单、合理，操作使用方便，夹紧定位可靠、稳定，夹紧力可调节，是一种理想的的曲轴轴颈定位夹紧装置。 The present invention adopts the above composition structure, and a movable and adjustable clamping rod is arranged on one side of the positioning block to position and clamp the workpiece. The utility model has the advantages of simple and reasonable structure, convenient operation and use, reliable and stable clamping and positioning, and adjustable clamping force, and is an ideal crankshaft journal positioning and clamping device.
