Description
技术领域technical field
本实用新型涉及机械加工技术领域，具体的说涉及一种数控铣床装夹监控系统。The utility model relates to the technical field of mechanical processing, in particular to a clamping monitoring system for a numerically controlled milling machine.
背景技术Background technique
在数控铣床加工零件的过程中，工件在实现定位后,由于在加工过程中受到加工力、重力等外力的作用，必须对工件施加夹紧力将其压紧夹牢。然而,如果夹紧力过小，工件处于不稳定状态，在外力作用下发生移动和转动，从而破坏工件在定位过程中获得的正确位置，损坏刀具以及数控铣床，容易甚至导致人身事故。当夹紧力过大，工件-夹具系统又将产生不当变形与表面损伤，最终导致工件位置偏移误差而影响工件的加工质量。In the process of CNC milling machine processing parts, after the workpiece is positioned, due to the processing force, gravity and other external forces in the processing process, a clamping force must be applied to the workpiece to press and clamp it firmly. However, if the clamping force is too small, the workpiece is in an unstable state, and it moves and rotates under the action of external force, thereby destroying the correct position of the workpiece obtained during the positioning process, damaging the tool and the CNC milling machine, and even causing personal accidents. When the clamping force is too large, the workpiece-fixture system will produce improper deformation and surface damage, which will eventually lead to the deviation of the workpiece position and affect the processing quality of the workpiece.
有鉴于此，如何提供一种数控铣床装夹监控系统用于检测夹具与工件之间的夹紧状态，控制夹具与工件之间的夹紧力就成了本领域技术人员亟需解决的技术问题。In view of this, how to provide a CNC milling machine clamping monitoring system for detecting the clamping state between the fixture and the workpiece, and to control the clamping force between the fixture and the workpiece has become a technical problem that those skilled in the art need to solve urgently .
实用新型内容Utility model content
本实用新型要解决的技术问题在于：如何提供一种数控铣床装夹监控系统用于检测夹具与工件之间的夹紧状态，控制夹具与工件之间的夹紧力。The technical problem to be solved by the utility model is: how to provide a CNC milling machine clamping monitoring system for detecting the clamping state between the clamp and the workpiece, and controlling the clamping force between the clamp and the workpiece.
一种数控铣床装夹监控系统，包括平口钳，所述平口钳由固定钳座与活动钳身构成，固定钳座与活动钳身能够相对运动以实现工件夹紧，其特征在于，所述固定钳座两侧设置有顶块或应变片，所述活动钳身两侧正对顶块或应变片设置有应变片或顶块，相互正对的顶块和应变片相互接触时，固定钳座与活动钳身之间留有和工件被夹持部位厚度一致的距离；还包括报警控制电路，所述报警控制电路中设置有PLC处理单元，所述PLC处理单元通过A/D转换器与所述应变片连接，所述报警控制电路中还设置有与所述PLC处理单元连接的警报器。A clamping and monitoring system for a CNC milling machine, comprising a vise, the vise is composed of a fixed clamp base and a movable clamp body, the fixed clamp base and the movable clamp body can move relatively to achieve workpiece clamping, it is characterized in that the fixed clamp Both sides of the clamp base are provided with top blocks or strain gauges, and the two sides of the movable clamp body are provided with strain gauges or top blocks facing the top blocks or strain gauges. When the mutually facing top blocks and strain gauges contact each other, the fixed clamp base A distance consistent with the thickness of the clamped part of the workpiece is left between the movable clamp body; an alarm control circuit is also included, and a PLC processing unit is arranged in the alarm control circuit, and the PLC processing unit communicates with the clamped part through the A/D converter. The strain gauge is connected, and the alarm control circuit is also provided with an alarm connected to the PLC processing unit.
这样，在装夹过程中，当工件与固定钳座和活动钳身同时接触时，顶块与应变片接触，在逐渐夹紧的过程中顶块顶住应变片使之变形量加大，即随着变形量的加大应变片产生一个随夹紧力变化的电信号，电信号通过A/D转换器转变为数字信号。这样在平口钳左右的应变片的形变经过转换均会产生一个数字信号。PLC处理单元通过接受到数字信号，可以判断两个应变片变形量是否一致、是否在允许形变范围内。若不一致则说明则说明工件装夹两边不一致，出现了偏斜或掉落，需要重新装夹。此时PLC处理单元通过警报器发出报警信息，通知操作人员重新装夹。若工件两边装夹一致，则通过PLC处理单元与其中预设值对比判断夹紧力的大小，是否超出允许误差范围。若超出PLC处理单元触发警报器，发出警报。In this way, during the clamping process, when the workpiece is in contact with the fixed clamp seat and the movable clamp body at the same time, the top block is in contact with the strain gauge, and during the gradual clamping process, the top block withstands the strain gauge to increase its deformation, that is, As the amount of deformation increases, the strain gauge produces an electrical signal that changes with the clamping force, and the electrical signal is converted into a digital signal through the A/D converter. In this way, the deformation of the strain gauges on the left and right sides of the vise will generate a digital signal after conversion. The PLC processing unit can judge whether the deformation of the two strain gauges is consistent and within the allowable deformation range by receiving the digital signal. If it is inconsistent, it means that the two sides of the workpiece clamping are inconsistent, and there is a deflection or drop, and it needs to be clamped again. At this time, the PLC processing unit sends out an alarm message through the alarm to notify the operator to reinstall the clamp. If both sides of the workpiece are clamped in the same way, the PLC processing unit is compared with the preset value to judge whether the clamping force exceeds the allowable error range. If the alarm is triggered by the PLC processing unit, an alarm will be issued.
