Technical Field

[0001] The utility model relates to the technical field of wheel production equipment, in particular to an automatic wheel grabbing device. Background Art

[0002] A wheel is a rigid wheel that secures the inner rim of the tire, supports the tire, and shares loads with the tire. The tire, rim, and spokes combined together are collectively referred to as a wheel. The wheel and tire together form the wheel assembly. During the production and molding process of passenger car wheels, it is often necessary to move the wheels and place them in a designated location for specific operations.

[0003] However, the assembly and movement process of the wheel is still very traditional, mainly relying on manual handling and operation, resulting in low work efficiency and high work intensity. Therefore, there is an urgent need for an automatic wheel grabbing device. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0022] Some embodiments of the present invention are described below with reference to the accompanying drawings.

[0023] Example 1:

[0024] Combine Figure 1-3 As shown, this embodiment provides an automatic wheel gripping device, including: a main body mechanism 100.

[0025] Among them, the main mechanism 100 includes a guide rail 110, a slider 120 symmetrically arranged on the guide rail 110, an arc-shaped clamping plate 130 fixed at the bottom end of the slider 120, a first driving member 140 installed on the guide rail 110 and passing through the slider 120, a rotating seat 150 fixed at the top of the guide rail 110, a bracket 160 rotatably installed on the rotating seat 150, a second driving member 170 fixed on the bracket 160, and a collision detection member 180 installed on one side of the arc-shaped clamping plate 130 and passing through the arc-shaped clamping plate 130.

[0026] The guide rail 110 is used to install the slider 120 and limit the movement of the slider 120. Slide grooves are opened on the opposite inner sides of the guide rail 110, and slide bars 122 are fixed on both sides of the slider 120. The slide bars 122 slide and fit into the slide grooves to ensure the stability of the slider 120 during movement.

[0027] The slider 120 is used to install the arc-shaped splint 130 and drive the arc-shaped splint 130 to move. A threaded hole 121 is opened in the middle of the slider 120. At the same time, the first driving member 140 includes a double-headed screw 141 rotatably installed on the inner side of the guide rail 110 and a first motor 142 fixed to one side of the guide rail 110 and the shaft is fixedly connected to the end of the double-headed screw 141. The double-headed screw 141 passes through the threaded hole 121 and engages with the threaded hole 121. When the first motor 142 is started, it drives the double-headed screw 141 to rotate. The rotation of the double-headed screw 141 drives the sliders 120 on both sides to move toward each other, that is, drives the arc-shaped splint 130 to move toward each other, thereby clamping and fixing the wheel.

[0028] The arc-shaped clamping plate 130 is used to clamp the wheel, and the collision detection member 180 is used to detect whether the arc-shaped clamping plate 130 is in contact with the wheel. It includes a shell 181 fixed to one side of the arc-shaped clamping plate 130, a feeler rod 182 movably arranged in the inner cavity of the shell 181 and with its end extending through the arc-shaped clamping plate 130, a collision sensor 183 installed on the inner bottom wall of the shell 181, and a spring 184 connecting the end of the feeler rod 182 to the inner bottom wall of the shell 181. The shell 181 is used to install other components to notify the limit of the movement of the feeler rod 182. When the arc-shaped clamping plate 130 contacts the outer side of the wheel, the feeler rod 182 can be compressed back into the inner cavity of the shell 181, and its end contacts the collision sensor 183, causing the collision sensor 183 to generate a contact signal, thereby turning off the first motor 142 to prevent the arc-shaped clamping plate 130 from continuing to move and causing damage to the wheel. The spring 184 is used to drive the feeler rod 182 to pop out of the shell 181 again after the wheel is released.

[0029] The rotating seat 150 includes a fixed block 151 symmetrically fixed on the top of the guide rail 110, a fixed shaft 152 arranged relative to the fixed block 151, and a worm gear 153 fixedly sleeved on the fixed shaft 152. The fixed block 151 is used to install the fixed shaft 152, and the fixed shaft 152 is used to install the worm gear 153. The bracket 160 includes a sleeve 162 rotatably sleeved on the fixed shaft 152 and a top plate 161 connecting multiple sleeves 162, so that the movable seat can rotate stably. At the same time, the second driving member 170 includes a second motor 171 fixed to the top of the bracket 160 and the shaft extending through the bracket 160, and a worm 172 fixed on the shaft of the second motor 171. The worm 172 and the worm gear 153 are engaged with each other. When the second motor 171 is started,. The worm 172 is driven to rotate, the worm 172 drives the worm wheel 153 to rotate, the worm wheel 153 drives the fixed shaft 152 to rotate, and the fixed shaft 152 drives the fixed block 151 to rotate, that is, the guide rail 110 and the arc-shaped clamping plate 130 on the guide rail 110 are driven to adjust their directions, making it convenient to clamp the vertical or horizontal wheels.

[0030] The working principle and use process of the present invention are as follows: when in use, the mobile mechanism is fixedly connected to the bracket 160, the second motor 171 is started, and the worm 172 is driven to rotate. The rotation of the worm 172 drives the worm wheel 153 to rotate. The rotation of the worm wheel 153 drives the fixed shaft 152 to rotate. The rotation of the fixed shaft 152 drives the fixed block 151 to rotate, that is, drives the guide rail 110 to rotate, adjusts the direction of the arc-shaped splint 130, and brings the guide rail 110 close to the wheel. The first motor 142 is started, and drives the double-headed screw 141 to rotate. The rotation of the double-headed screw 141 drives the sliders 120 on both sides to move toward each other, that is, drives the arc-shaped splints 130 on both sides to move toward each other. The wheel is clamped and fixed. When the arc-shaped clamping plate 130 contacts the outer side of the vehicle, the feeler rod 182 is compressed back into the inner cavity of the shell 181, and the end thereof comes into contact with the collision sensor 183. The collision sensor 183 detects the collision signal, turns off the first motor 142, and stops the movement of the arc-shaped clamping plate 130, thereby completing the clamping of the wheel. Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention. The scope of the present invention is defined by the claims and their equivalents.
