Description
技术领域:Technical field:
本实用新型属于车床配件领域,特别涉及一种安全、安装简便的成组车夹具配重块结构的改良。The utility model belongs to the field of lathe accessories, in particular to the improvement of a safe and easy-to-install group vehicle fixture counterweight structure.
背景技术:Background technique:
在批量车削工件时常用到车夹具,车夹具是随车床的主轴一起旋转的,由于工件的形状以及它的定位、夹紧的需要,夹具的总体结构一般都是不平衡的。生产加工时,由于离心力的作用,不平衡的不良后果就是将造成振动,从而影响了工件的加工精度和表面粗糙度,并加剧机床主轴和轴承的磨损。例如角铁式车床夹具,由于它的定位装置及其它元件总是安装在主轴轴线的一边,不平衡现象最严重,解决车夹具不平衡的方法之一就是设置配重块。如图1,车夹具1和配重块2。Turning fixtures are often used when turning workpieces in batches. The turning fixtures rotate together with the spindle of the lathe. Due to the shape of the workpiece and its positioning and clamping requirements, the overall structure of the fixture is generally unbalanced. During production and processing, due to the action of centrifugal force, the adverse consequence of imbalance is that it will cause vibration, which affects the machining accuracy and surface roughness of the workpiece, and aggravates the wear of the machine tool spindle and bearings. For example, the angle iron lathe fixture, because its positioning device and other components are always installed on one side of the spindle axis, the unbalance phenomenon is the most serious. One of the methods to solve the unbalance of the lathe fixture is to set the counterweight. As shown in Figure 1, the vehicle fixture 1 and the
设置配重块时有两种的形式:如果一个车夹具只是用来加工一种类型的工件,那所设置的配重块可以采用固定的形式;如果这个车夹具需要用来加工成组工件的,由于所加工的工件是成系列的,其形状、重量都有差别,配重块的重量也应当有所不同。通常的解决办法就是设计几块形状相同但厚度不同的配重块,这样可以根据不同工件的要求来增加或减少配重块的数量,从而达到夹具的平衡。There are two forms of setting the counterweight: if a jig is only used to process one type of workpiece, then the set counterweight can be in a fixed form; if the jig needs to be used to process a group of workpieces , because the processed workpieces are in series, and their shapes and weights are different, the weight of the counterweight should also be different. The usual solution is to design several counterweights with the same shape but different thicknesses, so that the number of counterweights can be increased or decreased according to the requirements of different workpieces, so as to achieve the balance of the fixture.
在车夹具上所设置的配重块,在固定时要求安全、简便。特别是设置成组车夹具的配重块时,由于有增加配重块数量的要求,更是要求拆装方便,这就需要对目前常用的配重块结构进行改进设计。目前常见的配重块结构总要有以下几种形式:The counterweight set on the vehicle fixture is required to be safe and easy to fix. Especially when the counterweights of the clamps of the group of vehicles are arranged, due to the requirement of increasing the number of counterweights, it is required to be easy to disassemble, which requires an improved design of the currently commonly used counterweight structure. At present, the common counterweight structure always has the following forms:
(1)如图2所示,配重块2上有两个开口长槽21,固定配重块2时可以把两开口长槽21插进成组车夹具上固定的两根螺杆,然后锁紧螺杆上的六角螺母3。这种结构装拆方便,但它加强了简便性却忽略了更为重要的安全性,在加工时,如果螺杆上的六角螺母松了,在离心力作用下,配重块就可能飞出伤人。(1) As shown in Figure 2, there are two long open slots 21 on the
(2)如图3所示,配重块2上只加工了两个通孔22,固定配重块2时,先把螺杆上的六角螺母3松脱下来,然后把配重块2套进螺杆,再六角螺母3。这种结构有足够的安全性,但是在每一次增减配重块的数量时,都必须把六角螺母3完全取下,失去了它的简便性。(2) As shown in Figure 3, only two through holes 22 are processed on the
(3)如图4所示,配重块2上加工了两个直径不同的孔23,小孔的直径一般比锁紧螺杆直径大0.5-1mm,大孔的直径比六角螺母3的外接圆直径e大2-3mm,固定配重块时,可把大孔对准带六角螺母3的锁紧螺杆套下,再移动配重块2,小孔套紧螺杆,然后锁紧六角螺母3。这种结构也有较好的简便性,但还是存在安全隐患,因为大孔比六角螺母3的外径大,如果六角螺母3松了,配重块还是有脱出的可能。(3) As shown in Figure 4, two
如何克服现有技术的不足,设计一种既满足方便更换,又使用安全的配重块,即成为本实用新型研究的对象。How to overcome the deficiencies in the prior art and design a counterweight that is both convenient to replace and safe to use becomes the object of study of the present invention.
发明内容:Invention content:
本实用新型旨在克服现有配重块之设计缺陷,设计一种槽孔只允许锁固六角螺母特定角度套入的成组车夹具配重块结构。The utility model aims at overcoming the design defect of the existing counterweight, and designs a group of vehicle fixture counterweight structure in which the slot hole only allows locking hex nuts to be inserted at a specific angle.
本实用新型技术方案是这样实现的:一种成组车夹具配重块结构,包括配重块本体和并排开设有的两个槽孔,其特征是槽孔由半圆螺杆孔和方槽孔连体而成,方槽孔的边长介于锁紧六角螺母的内切圆和外切圆直径之间。更换配重块时,只需将两粒六角螺母的方向调节一致,即可取出或者放入,而后再旋紧螺母即可,作业时,即使六角螺母被振松,只要两粒六角螺母不被振动至同一特定角度,即可确保配重块不飞出或脱出。The technical solution of the utility model is realized in the following way: a counterweight structure of a group vehicle fixture, including a counterweight body and two slotted holes arranged side by side, which is characterized in that the slotted holes are connected by a semicircular screw hole and a square slotted hole. It is made of a solid body, and the side length of the square slot hole is between the diameters of the inscribed circle and the circumscribed circle of the locking hexagon nut. When replacing the counterweight, you only need to adjust the direction of the two hexagon nuts to be consistent, then you can take it out or put it in, and then tighten the nuts. During operation, even if the hexagon nuts are loosened by vibration, as long as the two hexagon nuts are not broken Vibrating to the same specific angle ensures that the counterweight does not fly out or fall out.
所述配重块为圆弧结构,槽孔的半圆螺杆孔朝弦一侧,方槽孔朝弧一侧,且两方槽孔相互平行。使得配重块在高速旋转时,其受力点在半圆螺杆孔一侧,配重块在此定位点上,不可能被振飞和振脱。The counterweight has a circular arc structure, the semicircular screw hole of the slot faces the chord side, the square slot faces the arc side, and the two square slots are parallel to each other. When the counterweight rotates at a high speed, its stress point is on one side of the semicircular screw hole, and the counterweight cannot be vibrated or shaken off at this positioning point.
本实用新型具有设计合理、结构简单、装配更换方便、使用安全的特点。采用槽孔与六角螺母的配合,达成既方便更换操作,又确保加工时的安全。The utility model has the characteristics of reasonable design, simple structure, convenient assembly and replacement, and safe use. The combination of the slotted hole and the hex nut not only facilitates the replacement operation, but also ensures the safety during processing.
