Abstract
The utility model relates to the field of spare part assembling, in particular to an automobile engine assembling anti-error device. A motor-driven tightening gun anti-error system comprises a floating rod support, an installment plate, an inducing piece supporting plate, a sensor and sensing piece sets. One end of the installment plate is fixedly installed at the upper end of the floating rod support, and the other end of the installment plate is fixedly connected with a motor-driven tightening gun suspension system. The sensor is totally provided with three axis annular arrays which surround the floating rod support are installed at the lower end of the floating rod support through the installment plate. A plurality of sensing piece sets are arranged, and are successively arranged on the inducing piece supporting plate after being coded. When the motor-driven tightening gun anti-error system works, the inducing piece sets are matched with the sensor so as to ensure that the sensor outputs different signal values when bolts on different positions are tightened, and then the different signal values are identified through a controller, and afterwards the controller sends a signal whether a motor-driven tightening gun operates or not so as to ensure that bolts can only be tightened or loosened on right positions through the motor-driven tightening gun. The motor-driven tightening gun anti-error system is simple in structure, convenient to use, and high in reliability.
Description
Technical field

Background technology
Present Vehicle Engine Structure is very complicated, above bolt a lot, so when assembly and disassembly, be easy to occur twist the operate miss of wrong bolt; In case this type of problem occurs, just may damage engine, cause damage; Existing patent name " fail-safe system that is used for assembly line ", patent publication No.: CN201923633U.This novel patent relates to a kind of fail-safe system, relates in particular to a kind of fail-safe system for assembly line.Comprise control cabinet, described control cabinet is connected with fail-safe system, and described fail-safe system comprises control panel, product selector switch, inductor and the induction indicator lamp that finishes, and described control panel is provided with product selector switch, inductor and the induction indicator lamp that finishes.The fail-safe system that is used for assembly line promotes product quality, avoids accident to take place.This patent mainly be about the design of mistake proofing electric-control system hardware not in conjunction with engineering reality, practicality is relatively poor.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of electric tightening rifle fail-safe system; this system is by the sensing chip signal of three sensor identification diverse locations; guarantee the different signal value of sensor output when tightening the diverse location bolt; identify by controller then; then controller sends the signal that whether operates for the electric tightening rifle; assurance electric tightening rifle can only be tightened in right position or looser a bolt; and the floating lever height adjustment mechanism that is cooperated by rod member groove and holding screw; sensor protection mechanism and aluminium sheet that sensor and nylon baffle cooperate, the induced signal match mechanism that sensing chip is formed.
The utility model is achieved in that a kind of electric tightening rifle fail-safe system, comprise floating lever support, installing plate, sensing chip support plate, sensor and sensing chip group, described installing plate one end is fixedly mounted on the upper end of floating lever support, and the installing plate other end and electric tightening rifle suspension are fixedly linked; Described sensor has three lower ends that are installed in the floating lever support around the axle center of floating lever support annular array by installing plate; Described sensing chip group has some groups, arranges in turn behind the some groups of sensing chip group codings to be arranged on the sensing chip support plate, and the sensing chip group matches with sensor.
Have chute on the described floating lever support, an end of described installing plate is installed on the chute by hold-down screw is fastening.
The protection backing plate is equipped with in the bottom of described installing plate, has the exploration hole that adapts with the sensor sensing head on the described protection backing plate.
On the described floating lever support buffer spring is housed.
The utility model electric tightening rifle fail-safe system is by the sensing chip signal of three sensor identification diverse locations, guarantee the different signal value of sensor output when tightening the diverse location bolt, identify by controller then, then controller sends the signal that whether operates for the electric tightening rifle, and assurance electric tightening rifle can only be tightened in right position or looser a bolt.Simultaneously by the floating lever support that is connected with electric tightening rifle fixed head with tighten the synchronous movement of rifle, can the free adjustment height, also played the effect of protection sensor simultaneously, simple in structure, easy to use, the reliability height.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model statement, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
As shown in Figure 1, 2, 3, a kind of electric tightening rifle fail-safe system, comprise floating lever support 1, installing plate 2, sensing chip support plate 3, sensor 4 and sensing chip group 5, described installing plate 2 one ends are fixedly mounted on the upper end of floating lever support 1, and installing plate 2 other ends and electric tightening rifle suspension are fixedly linked; Described sensor 4 has three lower ends that are installed in floating lever support 1 around the axle center of floating lever support 1 annular array by installing plate 8; Described sensing chip group 5 has some groups, arranges in turn behind some groups of sensing chip groups 5 codings to be arranged on the sensing chip support plate 3, and sensing chip group 5 matches with sensor 4.
When using native system, at first the floating lever support 1 of this electric tightening rifle fail-safe system rifle fixed head of tightening by installing plate 2 usefulness screw threads and electric tightening rifle suspension is coupled together surely; Then be installed at assembly line and tighten or when unscrewing engine and needing each station of many groups bolt of mistake proofing, utilize the fixing hole on the sensing chip support plate 3 sensing chip support plate 3 to be installed on the fixed position of this station engine by bolt; Tighten gun system tighten or looser a bolt the group process in, floating lever support 1 is along with electric tightening rifle suspension is mobile together, by three sensors, the 4 identification sensing chip groups 5 on the floating lever support 1, being tighted a bolt to confirm is to belong to which group, is determining whether to start the electric tightening rifle then.
