Detailed Description

The present invention will be further described with reference to the following embodiments. Wherein the showings are for the purpose of illustration only and are shown by way of illustration only and not in actual form, and are not to be construed as limiting the present patent; for a better understanding of the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

As shown in fig. 1, the error-proofing system of the screw tightening machine with single-axis reaction force arm in the present embodiment includes a tightening machine 2, a clamp 3, a stamper 4 and a controller 5, which are disposed on a tooling table 1, wherein the tightening machine 2 adopts the single-axis reaction force arm to provide a tightening force to a portion of a workpiece (not shown) where a screw needs to be screwed; the fixture 3 has a fixed clamping effect on the workpiece, a plurality of fixtures are arranged according to the shape and size of the workpiece and are reasonably arranged on the tool table, and the clamping driving force of the fixtures adopts a cylinder element; the controller 5 plays a role in controlling the opening and closing of the clamp 3; the stamper 4 plays a role in marking unqualified products; the clamp 3 and the stamper 4 are respectively driven by an air cylinder with an air-operated valve 6, the air-operated valve 6 plays a role in controlling the action of the respective air cylinder, and the air cylinder plays a role in pneumatically controlling the clamp 3 to clamp on the tool table or the stamper 4 to implement stamping action; the controller 5 is electrically connected to the clamp 3, the stamper 4, and the tightening machine 2, respectively, that is, the controller 5 controls the cylinder through the pneumatic valve 6 to control the opening and closing of the corresponding clamp 3 and the stamping of the stamper 4, the controller 5 is provided with a button for opening and closing the clamp 3 and an automatic or manual switching button for automatic or manual control, and the tightening machine 2 is connected through a relay (not shown) disposed in the controller 5 for recording the number of tightening times, and the relay is also in communication connection with the controller 5, and the information output of the tightening machine 2 is fed back to the controller 5 to be linked to the clamp 3 and the stamper 4. By adopting the scheme, the records of the processing hole sites are added in the tightening machine system, the hole sites which do not reach the standard or are not processed can be identified, error-proofing measures are provided for operation, meanwhile, a 'waste product' mark is directly marked when the product is unqualified, and an operator is prevented from mistakenly regarding the unqualified product as a qualified product.

The error proofing system in this embodiment further includes a proximity switch (not shown) disposed on the tooling table for detecting the tightening machine station and electrically connected to the controller 5. The tightening machine 2 is connected with the tool table 1 in a sliding mode through a sliding rail, and the proximity switch plays a role in detecting whether the tightening machine safely returns to the initial position after the tightening machine finishes working or not through the initial position of the sliding rail arranged on the tightening machine.

The mistake proofing system in this embodiment further includes an automatic conveying device 7 disposed in front of and behind the tool table 1, and the automatic conveying device 7 is an adhesive tape machine or a chain plate machine. The automatic feeding device has the functions of conveying workpieces, namely increasing the automatic feeding of workpiece feeding and discharging, facilitating workpiece taking of an operator and forming a production line working mode.

In use, when an operator uses the tightening machine to machine a workpiece, such as a rear bumper beam pulled by a vehicle, the workpiece is conveyed to the front end of the tightening machine through the automatic conveying device 7, the operator places the workpiece on the clamp 3 of the tooling table 1, then manually presses the 'off' button on the controller 5, and the clamp 3 automatically clamps the workpiece and is screwed up by the tightening machine 2. Such as the product: the vehicle pulls back crashproof roof beam and need tighten six screws under standard moment of torsion altogether. If the qualified product is produced normally, the operator has mounted the screw, needs to push the tightening machine 2 back to the safe position of the equipment, i.e. to touch the proximity switch, then manually presses the "open" button on the controller, the clamp 3 is opened, and the operator places the workpiece on the latter automatic conveyor 7 for transport to the next station, where the next piece of processing can be performed subsequently. If unqualified products are produced, if a hole position is missed to be screwed, the number of the unthreading hole positions can be displayed on a display screen of the screwing machine 2 or the controller 5, meanwhile, the clamp 3 cannot be opened, a person in charge must use a key to drive the controller 5 to a manual gear, then an 'opening' button is pressed, a cylinder with a seal device 4 on the tool table 1 can synchronously act, waste products are printed on the surface of a workpiece, then the clamp 3 is opened, the waste workpiece is operated to be placed in a waste frame, and then the next processing can be carried out.

Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the scope of the claims of the present invention.
