Description

Automatic nutting bullet top centering body

Technical field

The utility model belongs to machinery production field, refers in particular to a kind of production line centering body.

Background technique

Horizontal position of the automatic nutting majority of production line between manual setting screwdriver bit and bolt at present guarantees center Line is on the same line.As shown in Figure 1, using existing nutting tool, including former extension bar 1 ', former connecting pin 2 ', former batch First 3 ', there are horizontal direction inclination angle a between bolt 5 ' and former screwdriver bit 3 ', when nut 4 ' and bolt 5 ' are screwed to together, carry out hand There are certain risks when dynamic centering adjustment, need repetitive operation, are not able to satisfy torque demand, and manual again after mounting Torque is verified, productive temp is thus affected, increases cost.

Summary of the invention

The utility model provides a kind of automatic nutting bullet top centering body, has wind to solve existing manual centering adjustment The problem of danger, repetitive operation, and be not able to satisfy torque demand affect productive temp, increased costs.

The technical solution of the utility model is: screwdriver bit is fixedly connected by connecting pin with extension bar, and copper sheathing is mounted on bearing In seat, bearing block is fixedly connected by screw with flange seat, and extension bar is fixedly connected by pin with unit is tightened, cylinder installation It is tightening below unit, on extension bar, spring one end is connect spring pocket with bearing block, and the other end has spring stop piece.

Utility model has the advantages that structure novel is compact, principle is simple, and cost performance is high, versatile in production, answers Wide with range, using effect is good, and current this structure has been successfully applied on the production assembly line of turbocharger.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model background technique；

Fig. 2 is the structural schematic diagram of the utility model；

Fig. 3 is the schematic cross-sectional view of the utility model；

Fig. 4 is the use state diagram of the utility model；

In figure, former extension bar 1 ', former screwdriver bit 3 ', nut 4 ', bolt 5 ', extension bar 1, connecting pin 2, is criticized former connecting pin 2 ' First 3, spring stop piece 4, spring 5, bearing block 6, flange seat 7, tighten unit 8, cylinder 9, copper sheathing 10, nut 11, screw 12.

Specific embodiment

Screwdriver bit 3 is fixedly connected by connecting pin 2 with extension bar 1, and copper sheathing 10 is mounted in bearing block 6, and bearing block 6 passes through spiral shell Nail is fixedly connected with flange seat 7, and extension bar 1 is fixedly connected by pin with unit 8 is tightened, and cylinder 9, which is mounted on, to be tightened under unit 8 Side, 5 sets of spring on extension bar 1,5 one end of spring is connect with bearing block 6, and the other end has spring stop piece 4.

The utility model increases flange seat and bearing block, spring are supported as horizontal adjustment, it is ensured that tightens nut 11 Torque is in acceptability limit；Meanwhile extension bar can be ajusted by increasing flange seat and bearing block and tighten between unit the One section of gap, so that extension bar be made to be ajusted；Since screwdriver bit is by, again there are gap, screwdriver bit will between gravity and connecting pin There are certain angles for lateral beat and 12 center line of screw, cause nut 11 that can not ajust when screwing in, and increase spring now and rise To effect is held out against, pressure overcomes gravity, ajusts screwdriver bit from end-acted, and nut 11 smoothly screws in screw 12.This is practical new The extensibility of spring is utilized in type, and when spring is given its external pressure by screwdriver bit, spring provides reaction force, by spring Baffle is held out against, and overcomes the gap between screwdriver bit and connecting pin, and screwdriver bit is ajusted, and nut 114 is screwed in when ajusting.

Claims (1)
