Problems solved by technology

Therefore, if the pre-positioning oil cylinder drives the workpiece pre-positioning pallet to drop down in place, or if the pre-positioning oil cylinder fails to move, it will cause improper clamping of the workpiece or the workpiece is not clamped. If processing is performed at this time, fixture damage and workpiece damage will occur. Dangerous situations such as falling and flying out of the knife break, there is a great potential safety hazard

Embodiment Construction

[0022] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0023] Such as Figure 1 to Figure 7 As shown, the feedback device 200 for detecting the lowered position of the workpiece pre-positioning tray 300 includes a main body 1 , an action rod 2 , a straight pin 3 , a spring plunger 4 and a gas sensor 101 . in:

[0024] refer to image 3 The main body 1 is fixed on a clamping body 7 through bolts 5, and the main body 1 includes a longitudinal through hole and a transverse air channel connected to each other, preferably vertically staggered, and the transverse air channel is connected by the longitudinal through hole. It is divided into a first airway 8 on the left side and a second airway 9 on the right side. Wherein, the left end of the first airway 8 is connected with the detection airway in the clamp body 7 (a detection airway is arranged inside the clamp body 7, and the detection airway is conn...

Abstract

The invention discloses a feedback device for detecting a descending position of a workpiecepretargeting tray. The feedback device comprises a main body, an action rod, a straight pin, a spring plunger and a gas sensitive element. Interior air passage is communicated and closed through reciprocation from top to bottom of the action rod, an oil cylinder is clamped and then a workpiece is clamped after the result detected by the gas sensitive element is fed back to a numerical control system. According to the feedback device, closed loop feedback of the pretargeting tray is achieved, accident damage of clamps is avoided, and potential safety hazard is eliminated.

Description

technical field [0001] The invention relates to a feedback device for detecting the lowering position of a workpiece pre-positioning pallet. Background technique [0002] The fixtures of the engine production line are generally hydraulic fixtures, and the workpiece pre-positioning tray is arranged on the fixture for the pre-positioning of the workpiece. The workpiece pre-positioning pallet is controlled by a pre-positioning cylinder to move up and down. When the workpiece pre-positioning pallet is lowered to the set position, each clamping cylinder clamps the workpiece on the pallet. [0003] At present, the action control of the above-mentioned pre-positioning oil cylinder is an open-loop control, which is carried out by the numerical control system of the machine tool according to the set program, and lacks effective detection feedback. Therefore, if the pre-positioning oil cylinder drives the workpiece pre-positioning pallet to drop down in place, or if the pre-position...
