Description

Technical Field

[0002] Door gripper robotic arms are mainly used in automobile manufacturing and assembly processes and have the following main functions: they can flexibly grasp and manipulate car doors, helping workers to install and debug car doors more easily. There is usually a gripper or clamp device at the end of the robotic arm to firmly grasp the door handle or other parts.

[0003] At present, in order to adapt to the grabbing of various car doors, the car door glass installation seam is used as the focus of grabbing, because the width of the glass installation seam varies in a very small range. However, during the use of the car door mechanical arm grabber in the prior art, the vertical part of the n-type bottom plate set at the bottom of the grabber, which is close to the outer side of the car door, is generally inserted into the glass installation seam of the car door sheet metal, and manual operation is required. Then, the two L-type grabbers are driven by the gear group transmission structure to rotate and lock the inner wall of the car door glass installation seam to achieve the gripping of the car door, and the grabbed car door is manually transported to the frame for manual installation through a movable lifting guide device. However, when the n-type bottom plate and the two L-type grabbers are manually inserted into the glass installation seam at the same time, because it is manually controlled, the speed, angle and strength of the insertion are difficult to control, which causes the n-type bottom plate and the two locking claws to inevitably scratch the paint surface at the edge of the glass installation seam during the insertion process, thereby causing the surface paint surface or the inner lining surface of the car door to be scratched. Therefore, the present application provides a multi-type car door grabber to meet the needs. Summary of the invention

[0028] Among them, the movable groove is not shown in the accompanying drawings. The movable groove is located in the middle of the bottom end of the bottom shell 13, and the width of the movable groove is larger than the cross-sectional width of the two L-shaped grippers 15, which can facilitate the two L-shaped grippers 15 to rotate through the top rotating shaft 14; and the gear group transmission structure adopts electric drive, and the push switch 17 is electrically connected to the control box 12, and the control box 12 is electrically connected to the gear group transmission structure, so that when the push switch 17 is pressed, it can prompt the gear group transmission structure to drive the rotating shaft 14 to drive the two L-shaped grippers 15 to rotate and lock the inner wall of the glass installation seam 21.

The middle part of one end of the guide plug plate 34 away from the first reset spring piece 311 is fixed to the outer wall of the second U-shaped support frame 32 through the second reset spring piece 35. The shape of the second reset spring piece 35 is the same as that of the first reset spring piece 311, and both are "Ω"-shaped structures. The two symmetrically distributed through grooves provided on the lateral baffle plate 33 are both integrally formed with a first adapter spring piece 36, and the two symmetrically distributed through grooves provided on the two side walls of the guide plug plate 34 are also integrally formed with a second adapter spring piece 37.

[0030] The two side walls of the guide plate 34 are provided with two symmetrically distributed movable channels 342. Fig. 9As shown, when the two L-shaped grippers 15 are driven to rotate by the gear transmission structure through the rotating shaft 14, the two L-shaped grippers 15 can be extended from the two movable channels 342 close to the lateral baffle plate 33 respectively, effectively preventing the guide plug plate 34 from being solid and affecting the two L-shaped grippers 15 from grabbing the door sheet metal body 2; the setting of the arc-shaped avoidance portion 331 prompts the lateral baffle plate 33 to follow the guide plug plate 34 to be inserted into the glass installation seam 21, and can actively avoid the edge of the inner surface of the door sheet metal body 2, avoiding the vertical part of the side of the n-shaped bottom plate 16 away from the inverted L-shaped handle 18 from directly hitting the edge of the inner surface of the door sheet metal body 2, playing a good protective role; the guide plug plate 34 cooperates with four second adapter elastic The arrangement of the first and second adapting spring pieces 37 enables the guide plug plate 34 to be adapted to glass installation seams 21 of different widths, and facilitates pre-positioning for glass installation seams 21 of different widths, so that the mechanical gripper body 1 can be adapted to various types of vehicle doors for grabbing, and has a wide range of applications; the four second adapting spring pieces 37 and the two second adapting spring pieces 37 enable the guide plug plate 34 and the side baffle plate 33 to be more firmly mounted on the n-type bottom plate 16, and the arrangement of the first weakening groove 341, in conjunction with the arrangement of the two first reset spring pieces 311, enables the guide plug plate 34 to be designed with two side walls of the guide plug plate 34 being inclined outward before being inserted into the glass installation seam 21, and the side baffle plate 33 is closer to the guide plug plate 34; Figure 5 This is the state after the auxiliary component 3 is inserted into the glass installation gap 21 .

[0031] like Figures 2 to 10As shown, in order to enable the guide plug plate 34 and the lateral baffle plate 33 to be quickly withdrawn from the glass installation gap 21 when the push switch 17 needs to be squeezed, two first reset springs 311 are provided, both ends of which are fixedly connected to the middle of the first transmission column 38, and both ends of the second reset spring 35 are fixedly connected to the middle of the second transmission column 39. The outer side of each first transmission column 38 is movably sleeved with a first V-shaped rod 382, ​​and the first V-shaped rod 382 is fixed to the outer wall of the first U-shaped support frame 31. The first V-shaped rod 382 is provided with a first inclined groove 381 adapted to the diameter of the first transmission column 38, and the outer side of each second transmission column 39 is movably sleeved with a second V-shaped rod 313, and the second V-shaped rod 313 is fixed to the outer wall of the second U-shaped support frame 32, and the second V-shaped rod 313 is provided with a second inclined groove 314 adapted to the diameter of the second transmission column 39, and the outer sides of the two first transmission columns 38 and the second transmission columns 39 on the same side are movably sleeved with the same transmission cross bar 310, and the two transmission cross bars are movably sleeved. The rods 310 are provided with transmission channels 312, which are used to drive the two first transmission columns 38 and the second transmission columns 39 on the same side to move downward synchronously. The bottom ends of the two transmission cross bars 310 are respectively fixed with the first lifting rod 315 and the second lifting rod 316. The first lifting rod 315 is movably inserted on the first U-shaped support frame 31, and the second lifting rod 316 is movably inserted on the second U-shaped support frame 32.

When the finger presses the pressing portion 322, the bottom of the arc-shaped pressing plate 318 will move downward, and with the setting of the avoidance groove 321, it is not easy for the inverted L-shaped handle 18 to block its downward movement. In addition, the setting of the second weakening groove 319 and the two third weakening grooves 320 makes it easy for both ends of the arc-shaped pressing plate 318 to deform, and the inner arc surface of the arc-shaped pressing plate 318 is pressed to straighten, and at the same time, it can press the press switch 17.

[0033] The present invention also provides a method for using multiple types of door grippers, comprising the following steps: Step 1: manually hold the inverted L-shaped handle 18, pull the bottom shell 13 downward, and insert the vertical part of the n-shaped bottom plate 16 close to the inverted L-shaped handle 18 into the glass installation seam 21. With the help of the setting of the auxiliary component 3, the vertical part of the n-shaped bottom plate 16 close to the inverted L-shaped handle 18 and the two L-shaped grippers 15 will not cause impact on the position of the glass installation seam 21 during the process of inserting into the glass installation seam 21; Step 2: When taking out the n-shaped bottom plate 16 and the two L-shaped grippers 15, the inverted L-shaped handle 18 can be held by hand, and the pressing portion 322 thereon can be pressed with fingers. At the same time, with the help of the setting of the auxiliary component 3, the top sides of the guide plug plate 34 can be deformed toward the middle position respectively, and the top of the side baffle 33 can be deformed away from the first U-shaped support frame 31. The above coordinated operation, plus the setting of the auxiliary component 3 to guide the guide plug plate 34 and the side baffle 33 to deform, can make them be taken out from the glass installation seam 21.

[0034] The working principle of the technical solution provided by the present invention is as follows: The operator can hold the inverted L-shaped handle 18 and pull the mechanical gripper body 1 to move downward from the lifting guide rail device, and with the help of the two inclined surfaces set at the bottom of the guide plug plate 34, the guide plug plate 34 and the vertical part of one side of the n-shaped bottom plate 16 close to the inverted L-shaped handle 18 can be quickly and accurately inserted into the glass installation gap 21, and the arc-shaped avoidance part 331 at the bottom of the lateral baffle 33 can actively avoid the inner surface of the door sheet metal body 2, thereby effectively ensuring that the n-shaped bottom plate 16 and the two L-shaped grippers 15 are quickly and accurately inserted into the glass installation gap 21, and are not easy to be The edge of the glass installation seam 21 is hit, which effectively improves the use efficiency of the mechanical gripper body 1 and protects the outer surface paint surface of the door sheet metal body 2 from being damaged. In addition, when the vertical portion of one side of the n-type bottom plate 16 close to the inverted L-shaped handle 18 is inserted into the glass installation seam 21, it can use the elastic effect of the first adapter spring piece 36 and the second adapter spring piece 37 to prompt the n-type bottom plate 16 to be pre-positioned at the glass installation seam 21. After that, the artificial finger extends into the avoidance groove 321 to press the push switch 17, thereby prompting the rotating shaft 14 to drive the two L-shaped grippers 15 as shown in the attached Figure 5The two L-shaped grippers 15 are rotated clockwise as shown in the figure, so that the bottom ends of the two L-shaped grippers 15 are locked on the inner wall of the glass installation seam 21, thereby realizing the grabbing action of the car door. When the car door is lifted to the vehicle frame to be installed by manual movement, the pressing portion 322 can be manually squeezed by fingers to straighten the inner arc surface of the arc-shaped pressing plate 318, and while pressing the pressing switch 17, the bottom of the arc-shaped pressing plate 318 can drive the two inverted L-shaped rods 317 to move downward, and the two L-shaped grippers 15 are rotated to a vertical state at this time. Due to the arrangement of the first lifting rod 315 and the second lifting rod 316, the two transmission cross bars 310 can move downward stably and vertically. In addition, combined with the transmission channel 312 opened on the transmission cross bar 310, the two first transmission columns 38 and the second transmission columns 39 arranged on both sides can be moved simultaneously. However, with the help of the first inclined groove 381 on the first V-shaped rod 382 and the second inclined groove 314 on the second V-shaped rod 313, the middle parts of the two first reset spring pieces 311 are driven to move downward respectively, and move downward in an inclined manner, and the second reset spring piece 35 is also driven to move downward at the same time, and moves downward in an inclined manner, so that the top sides of the guide plug plate 34 can be squeezed and deformed toward the middle direction, and at the same time, the top of the lateral baffle plate 33 is squeezed and deformed in the direction away from the first U-shaped support frame 31, so that the guide plug plate 34 can be quickly pulled out of the glass installation gap 21, and the lateral baffle plate 33 is simultaneously taken away, which greatly improves the effect of the auxiliary component 3 being able to be quickly pulled out of the glass installation gap 21 after use, and avoids the problem of difficulty in pulling out due to excessive pre-positioning force.
