Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts, and specifically includes an automobile wheel hub bolt hole coating protection automatic picking claw head. BACKGROUND

[0002] The wheel hub needs to be protected and isolated before spraying to prevent the bolt hole from being polluted by the spraying operation and affecting the assembly precision. Figure 1 Currently, spherical caps or rod caps are mainly used to protect and plug the wheel hub bolt hole, wherein the rod cap is plugged, and the rod body is exposed for manual protection removal.

[0003] During the wheel hub protection automatic picking process, due to mixed line production of the wheel hub, different types of protection are used for different types of wheel hubs, and one claw head cannot pick different shapes of protection at the same time, so the claw head needs to be frequently replaced. UTILITY MODEL CONTENTS

[0004] The utility model solves the technical problem of how to pick different shapes of protection at the same time.

[0005] In view of the above-mentioned problems, the utility model provides an automobile wheel hub bolt hole coating protection picking claw head, which includes a switching rotary part, a spherical protection suction claw head installed on the rotary end of the switching rotary part, and a rod protection clamping claw head.

[0006] The rod protection clamping claw head is a pneumatic three-jaw chuck, and the rod body clamping claw is installed on the jaw of the three-jaw chuck.

[0007] The rod body clamping claw is an L-shaped structure, one end of the rod body clamping claw is installed on the jaw through a fastener, and the other end of the plurality of rod body clamping claws forms a rod body clamping channel.

[0008] The switching rotary part is a rotary air cylinder or a rotary motor.

[0009] The utility model can realize suction and clamping of the spherical cap through the negative pressure suction head, can clamp the rod body of the rod cap through the rod body clamping claw, and realizes transfer of the spherical cap or the rod cap through the mechanical hand, so as to realize automatic removal of the spherical cap or the rod cap, improve the removal efficiency of the spherical cap or the rod cap, and reduce the labor cost and labor intensity. BRIEF DESCRIPTION OF DRAWINGS

[0010] Figure 1 It is the schematic view of the cooperation of the spherical protection, the protection with the rod and the automobile wheel hub.

[0011] Figure 2 It is the axial schematic view of the utility model.

[0012] The numbers in the drawing represent as follows: 1, spherical protection, 2, protection with the rod, 21, rod body, 3, switching rotary piece, 4, spherical protection adsorption claw head, 5, protection with the rod clamping claw head, 6, three-jaw chuck, 7, claw, 8, rod body clamping channel, 9, rotary end installation platform, 10, claw head installation plate. DETAILED DESCRIPTION

[0013] The utility model will be further explained in detail in connection with the embodiment and the drawing as follows:

[0014] As Figure 2 shown, the utility model discloses an automobile wheel hub bolt hole coating protection automatic picking claw head, including switching rotary piece 3 and protection picking mechanism, and the protection picking mechanism includes spherical protection adsorption claw head 4 and protection with the rod clamping claw head 5, and switching rotary piece 3 can adopt rotary cylinder or rotary motor. Spherical protection adsorption claw head 4 includes the negative pressure suction head for adsorbing spherical protection 1, and the head opening of negative pressure suction head is provided with the ball socket that cooperates with spherical protection 1, and negative pressure suction head is connected negative pressure fan and so on negative pressure source, and protection with the rod clamping claw head 5 includes the rod body clamping claw through relative motion to hold the rod body 21 of protection with the rod 2. Thus, through negative pressure suction head can realize the adsorption clamping of spherical protection 1, and through rod body clamping claw 7 can hold the rod body 21 of protection with the rod 2, realizes the automatic taking out of spherical protection 1 or protection with the rod 2, improves the taking out efficiency of spherical protection 1 or protection with the rod 2, reduces the artificial cost and labor intensity.

[0015] In the embodiment, protection with the rod clamping claw head 5 is pneumatic three-jaw chuck 6, and claw 7 is installed on the claw 7 of three-jaw chuck 6, and the interval between claw 7 is 120 degrees, and relative three-jaw chuck 6 center synchronous sliding. And the claw 7 is L-shaped structure, and one end of L-shaped structure is installed on the claw 7 through screw and other fasteners, and the other end of multiple L-shaped structures forms rod body clamping channel 8, so as to realize the clamping or putting down of rod body 21.

[0016] Although the utility model has disclosed as above with preferable embodiments, however, is not used to limit the utility model. Any skilled person in the art, without departing from the utility model technical scheme range, can utilize the above disclosed technical content to make many possible changes and modifications to the utility model technical scheme, or modify as equivalent variation equivalent embodiment.
