The utility model aims to solve the technical problem that an electronic self-plugging rivet riveting tool at riveting initial position locking rivet is about to provide.

In order to solve the technical problem above, the utility model provides an electronic self-plugging rivet riveting tool of pin rod locking formula, a clamping sleeve is connected to the pull rod, clamping sleeve's hole is a circular cone hole, the rifle head stretches into clamping sleeve's hole, a spring is placed in the step hole of pull rod, a core is placed to the other end of spring, the claw piece of grabbing nail is in between rifle head and the core, the pull rod removes to the afterbody, the claw piece of grabbing nail breaks away from with the rifle head, the core will grab the claw piece and push to clamping sleeve's circular cone hole tip direction under the effect of spring force, make the claw piece of grabbing nail remove towards the axle center and carry the rivet pin pole, riveting tool has just locked the pin pole of rivet when initial position, prevent to drop.

The contact surface of the nail grabbing claw sheet and the gun head is an inclined plane, the top core pushes the nail grabbing claw sheet to the gun head under the action of the spring force, the gun head contact end pushes the nail grabbing claw sheet to the inner wall of the conical hole of the clamping sleeve through the inclined plane, an inscribed circle formed by the nail grabbing claw sheet is larger than the diameter of the rivet rod, and the rivet rod can smoothly pass through the tangent circle.

The pull rod is connected with the driving part through the transmission mechanism, the driving part is connected with the control panel, the control panel is connected with the locking starting module, the locking starting module sends a signal to the control panel, and the control panel controls the driving part to rotate to drive the pull rod to move towards the tail part.

After the rivet rod of the rivet is arranged in the gun head of the riveting tool, only the locking starting module needs to be selected, and the rivet rod is clamped by the rivet grabbing claw pieces, so that the rivet is prevented from falling.

The utility model has the advantages that: the riveting tool has the advantages that the function of locking the rivet is added at the initial position, and the usability and the efficiency of the tool are improved.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 and fig. 2 show the structure schematic diagram of the non-locking nail rod of the embodiment of the present invention, and fig. 3 and fig. 4 show the structure schematic diagram of the locking nail rod of the embodiment of the present invention. As shown in fig. 1-4, the utility model provides an electronic self-plugging rivet riveting tool of nail pole locking formula, a clamping sleeve 4 is connected to pull rod 5, and clamping sleeve 4's hole is a taper hole, and rifle head 2 stretches into clamping sleeve 4's hole, and a spring 12 is located the step hole of pull rod 5, and a top core 11 is placed to the other end of spring 12, and claw piece 3 is in between rifle head 2 and the top core 11.

The selection button 9 selects 'locking', correspondingly, a locking indicator lamp of the function display part 10 is lightened, the start button 8 is clicked, a signal is sent to the control board 7, the control board 7 enables the motor 6 to rotate for N circles in the forward direction, the clamping sleeve 4 moves towards the arrow direction in the figure 3 along with the pull rod 5, the nail grabbing claw piece 3 is separated from the gun head 2, the ejection core 11 pushes the nail grabbing claw piece 3 to the small end direction of the conical hole of the clamping sleeve 4 under the action of spring force, the nail grabbing claw piece 3 moves towards the axis to clamp the nail rod of the rivet 1, the riveting tool locks the nail rod of the rivet at the initial position, and the rivet is prevented from falling. The rivet 1 is plugged into the riveting hole of the workpiece, the start button 8 of the riveting tool is pressed again, a signal is sent to the control board 7, the control board 7 drives the motor 6 to rotate forward again, the clamping sleeve 4 drives the nail grabbing claw piece 3 to continuously move along with the screw rod 5 towards the arrow direction in the drawing 3 until the rivet rod of the rivet 1 is broken to complete riveting.
