Description
Technical Field
The utility model relates to a screw thread quality testing technical field, concretely relates to module is patrolled and examined to automatic screw thread of nut.
Background
The condition that welding slag splashes often can appear in the welding process to the work piece, if the welding slag glues and can not in time get rid of on the screw tooth of nut, can form the defective products because the screw can't be screwed in, cause the unable normal use of customer and influence the public praise, consequently need carry out the screw tooth to the nut of product and patrol and examine, nevertheless adopt artifical manual mode to patrol and examine the screw tooth, its inspection efficiency is low, has influenced production efficiency, and has increased the human cost.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a module is patrolled and examined to automatic screw thread of nut on the nut, its can be automatically patrolled and examined to the screw thread of nut on the work piece, and the inspection is accurate, has improved production efficiency, has reduced the human cost.
The utility model discloses the above-mentioned technical problem that will solve realizes through following technical scheme:
the utility model provides a module is patrolled and examined to automatic thread of nut, includes fixing base, sliding seat, cylinder, servo motor and pivot, the sliding seat about slidable mounting in the fixing base and by the cylinder drive, servo motor be fixed in on the sliding seat, just servo motor's output shaft down, servo motor's output shaft fixed connection in the upper end of pivot, the lower extreme periphery cover of pivot have the sleeve, the sleeve pass through spring fixed connection in the pivot, telescopic periphery be provided with the external screw thread, the sliding seat be fixed with proximity switch, proximity switch be located telescopic one side, proximity switch circuit connection in cylinder and servo motor respectively.
Preferably, a sliding block is arranged behind the sliding seat, a guide rod is vertically fixed on the fixed seat, the sliding block is sleeved on the guide rod, and the sliding block is fixedly connected to a telescopic rod of the cylinder. The cooperation structure of guide arm and sliding block make the slip of sliding seat more stable smooth and easy.
Preferably, the sliding seat is provided with more than two transverse plates, and the rotating shaft penetrates through the transverse plates and is rotatably connected with the transverse plates through bearings. The design of the structural scheme enables the rotation of the rotating shaft to be more stable.
Has the advantages that: after adopting the structure of the utility model, the air cylinder controls the sliding seat to move downwards when in work, when the screw cap to be inspected is detected by approaching the lighting, the cylinder stops moving, the servo motor drives the rotating shaft to rotate, the sleeve elastically connected with the lower end of the rotating shaft gradually enters the nut to carry out inspection, when the sleeve is clamped due to thread damage, the load rate of the servo motor can be gradually increased, when the set load rate is exceeded, the alarm display is poor, thereby realizing automatic inspection of the screw threads of the screw cap on the workpiece, improving the production efficiency, reducing the labor cost, further, the sleeve is elastically connected on the rotating shaft through the spring, therefore, the sleeve can be controlled to move up and down to patrol teeth only by positive and negative rotation of the servo motor without moving the whole rotating shaft to move up and down, the structure is simpler, and the spring can effectively prevent the condition that the sleeve is in contact with the nut and damaged due to the detection error of the proximity switch.
Drawings
Fig. 1 is the structure schematic diagram of the automatic thread inspection module of the nut.
Fig. 2 is a schematic structural view of the present invention at the sleeve position.
Wherein: the device comprises a fixed seat, a sliding seat, a cylinder, a servo motor, a rotating shaft, a sleeve, a guide rod, a sliding block, a transverse plate, a proximity switch and a spring, wherein the fixed seat is 1, the sliding seat is 2, the cylinder is 3, the servo motor is 4, the rotating shaft is 5, the sleeve is 6, the guide rod is 7, the sliding block is 8, the transverse plate is 9, the.
