Description

Technical Field

[0001] The present invention relates to the technical field of vehicle door grabbers, and in particular to a multi-type vehicle door grabber and a use method thereof. Background Art

[0002] Door gripper robotic arms are primarily used in automotive manufacturing and assembly processes. They provide the following key functions: They can flexibly grasp and manipulate vehicle doors, making installation and commissioning easier for workers. The arm typically has a gripper or clamp at the end that securely grasps the door handle or other features.

[0003] Currently, in order to accommodate the gripping of various vehicle doors, the vehicle door glass mounting seam is primarily gripped because the width of the glass mounting seam varies very little. However, during use, conventional vehicle door robotic arm grippers generally insert a vertical portion of an N-shaped base plate, located at the bottom of the gripper and close to the outer side of the vehicle door, into the glass mounting seam of the vehicle door sheet metal. This requires manual operation. A gear transmission structure then drives two L-shaped grippers to rotate and lock the inner wall of the vehicle door glass mounting seam, thereby gripping the vehicle door. A movable lifting guide device is then used to manually transport the gripped vehicle door to the vehicle frame for manual installation. However, when the N-shaped base plate and the two L-shaped grippers are simultaneously manually inserted into the glass mounting seam, the manual operation makes it difficult to control the speed, angle, and force of the insertion. This inevitably causes the N-shaped base plate and the two locking claws to scratch the paint surface at the edge of the glass mounting seam during insertion, resulting in scratches on the surface paint or inner lining of the vehicle door. Therefore, the present application provides a multi-type vehicle door gripper to meet this need. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a multi-type vehicle door gripper. By setting an auxiliary component, on the one hand, it can facilitate the rapid and accurate insertion of the vertical portion on one side of the N-shaped base plate close to the outer side surface of the vehicle door into the glass installation seam of the vehicle door sheet metal, while also preventing the vertical portion on one side of the N-shaped base plate close to the outer side surface of the vehicle door and the two L-shaped grippers from causing impact and wear on the glass installation seam during the insertion process. On the other hand, it can enable the vertical portion on one side of the N-shaped base plate close to the outer side surface of the vehicle door to be pre-positioned in the glass installation seam, so as to solve the problem that the speed, angle and force of the N-shaped base plate when inserted into the glass installation seam during use of the existing vehicle door gripper are difficult to control, which causes the N-shaped base plate and the two L-shaped grippers to inevitably scratch the paint surface at the edge of the glass installation seam during the insertion process, thereby causing scratches on the surface paint surface or the inner lining surface of the vehicle door.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

The middle part of one end of the guide plug plate away from the first reset spring plate is fixed to the outer wall of the second U-shaped support frame through a second reset spring plate, and the shape of the second reset spring plate is the same as that of the first reset spring plate, and both are "Ω"-shaped structures.

[0009] Optionally, a first adapting spring piece is integrally formed in the two symmetrically distributed through grooves opened on the side baffle, and a second adapting spring piece is integrally formed in the two symmetrically distributed through grooves opened on both side walls of the guide plug plate. The shape of the first adapting spring piece is the same as that of the second adapting spring piece, and both are arc-shaped bending structures.

[0010] Optionally, the middle parts of both ends of the two first reset springs are fixed with a first transmission column, and the middle parts of both ends of the second reset springs are fixed with a second transmission column. The outer side of each of the first transmission columns is movably provided with a first V-shaped rod, and the first V-shaped rods are fixed to the outer wall of the first U-shaped support frame, and the first V-shaped rods are provided with a first oblique groove that is adapted to the diameter of the first transmission column. The outer side of each of the second transmission columns is movably provided with a second V-shaped rod, and the second V-shaped rods are fixed to the outer wall of the second U-shaped support frame, and the second V-shaped rods are provided with a second oblique groove that is adapted to the diameter of the second transmission column.

[0011] Optionally, the outer movable sleeves of the two first transmission columns and the second transmission columns on the same side are provided with the same transmission cross bar, and transmission channels are opened on the two transmission cross bars, and the transmission channels are used to drive the two first transmission columns and the second transmission columns on the same side to move downward synchronously.

[0012] Optionally, the bottom ends of the two transmission cross bars are respectively fixed with a first lifting rod and a second lifting rod, the first lifting rods are movably inserted on the first U-shaped support frame, and the second lifting rods are movably inserted on the second U-shaped support frame.

[0013] Optionally, the ends of the two transmission cross bars away from the lateral baffles are integrally formed with the same arc-shaped pressing plate through an inverted L-shaped rod, the top of the arc-shaped pressing plate is fixed to the front side wall of the bottom shell by two bolts, and an avoidance groove is opened at the middle position of the bottom of the arc-shaped pressing plate.

[0014] Optionally, a third weakening groove is provided at the connection points at both ends of the bottom of the arc-shaped pressing plate, a second weakening groove is provided at the connection point at the top of the arc-shaped pressing plate, and a pressing portion is provided in the middle of the surface of the arc-shaped pressing plate, and the pressing portion is made of a circular elastic rubber material.

[0015] The present invention also provides a method for using multiple types of vehicle door grips, comprising the following steps:

[0016] Step 1: Manually hold the inverted L-shaped handle and pull the bottom shell downward to insert the vertical portion of the N-shaped bottom plate near the inverted L-shaped handle into the glass installation gap. With the help of the auxiliary component, the vertical portion of the N-shaped bottom plate near the inverted L-shaped handle and the two L-shaped grippers will not cause any impact on the glass installation gap during the insertion process;

[0017] Step 2: When removing the n-shaped base plate and the two L-shaped grippers, you can hold the inverted L-shaped handle and press the pressing part on it with your fingers. At the same time, with the help of the setting of the auxiliary component, the top two sides of the guide plate can be deformed toward the middle position respectively, and the top of the side baffle can be deformed away from the first U-shaped support frame. The above coordinated operations, plus the setting of the auxiliary component to guide the guide plate and the side baffle to deform, can make it possible to remove it from the glass installation seam.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above scheme, by setting an auxiliary component, the guide plate is matched with the setting of four second adapter springs, and the bottom of the guide plate is provided with two symmetrically distributed inclined surfaces, so that the guide plate and the vertical part on one side of the n-shaped bottom plate close to the inverted L-shaped handle can be quickly and accurately inserted into the glass installation gap, and the arc-shaped avoidance part at the bottom of the side baffle actively avoids the inner surface of the door sheet metal body, thereby effectively ensuring that the n-shaped bottom plate and the two L-shaped grippers are quickly and accurately inserted into the glass installation gap, and are not prone to collision with the edge of the glass installation gap, effectively improving the use efficiency of the mechanical gripper body, and protecting the outer surface paint surface of the door sheet metal body from damage.

[0020] By providing the first and second adapting spring pieces, the vertical portion of the n-shaped base plate near the inverted L-shaped handle is inserted into the glass installation gap. At the same time, the n-shaped base plate can be pre-positioned in the glass installation gap by virtue of the elastic action of the first and second adapting spring pieces, thereby preventing the n-shaped base plate from shaking back and forth or left and right when being held, thereby preventing the two L-shaped grippers from locking and fixing the glass installation gap.

[0021] By providing an arc-shaped pressing plate, and the arc-shaped pressing plate is provided with a second weakening groove and two third weakening grooves, the manual squeezing of the pressing part is promoted, and the bottom of the arc-shaped pressing plate can be driven to move the two inverted L-shaped rods downward. Due to the provision of the first lifting rod and the second lifting rod, the two transmission cross bars are stably moved vertically downward. In addition, combined with the transmission channel opened on the transmission cross bar, the two first transmission columns and the second transmission columns provided on both sides can be moved downward synchronously. However, with the help of the first oblique groove opened on the first V-shaped rod and the second oblique groove opened on the second V-shaped rod, the middle parts of the two first reset spring pieces are driven downward respectively, and are moved downward in an inclined manner, and the second reset spring piece is also driven downward at the same time, and is moved downward in an inclined manner, so that the top two sides of the guide plate can be moved downward. The U-shaped support frame is pressed and deformed in the middle direction, and at the same time, the top of the side baffle is pressed and deformed in the direction away from the first U-shaped support frame, so that the guide plug plate can be quickly pulled out of the glass installation gap, and the side baffle is simultaneously taken away, which greatly improves the effect of the auxiliary component being able to be quickly pulled out of the glass installation gap after use, and avoids the problem of difficulty in pulling out due to excessive pre-positioning force. In addition, while manually squeezing the pressing part, combined with the setting of the avoidance groove, the inverted L-shaped handle will not block the arc-shaped pressing plate, so that the bottom of the arc-shaped pressing plate is in the process of moving downward, and its inner side wall can also squeeze the press switch, so that the two L-shaped grippers are driven by the gear group transmission structure to reset to a vertical state, and achieve the effect of being quickly and conveniently pulled out of the glass installation gap.

[0041] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a multi-type vehicle door gripper, including a mechanical gripper body 1, which also includes a support arm 11, and the bottom end of the support arm 11 is fixedly connected to a bottom shell 13 with a convex vertical cross-section. A control box 12 fixed to the outer wall of the support arm 11 is provided above the bottom shell 13. The interior of the bottom shell 13 is rotatably connected to a rotating shaft 14 near its inner bottom wall. The outer side of the rotating shaft 14 is fixedly connected to two symmetrically distributed L-shaped grippers 15, and the bottom ends of the two L-shaped grippers 15 pass through a movable groove opened at the bottom of the bottom shell 13. The middle part of the rotating shaft 14 is also connected to the inner wall of the bottom shell 13 through a gear set transmission structure, and the gear set transmission structure is also installed inside the bottom shell 13. An inverted L-shaped handle 18 is fixed to the middle of the front side wall of the bottom shell 13 near its bottom end, and the bottom end of the bottom shell 13 is away from the middle of the inverted L-shaped handle 18. An n-shaped base plate 16 is fixedly connected to the position, and the n-shaped base plate 16 is located between the two L-shaped grippers 15. A push switch 17 fixed to the middle of the front side wall of the bottom shell 13 is also provided above the inverted L-shaped handle 18. The vertical portion on one side of the n-shaped base plate 16 close to the inverted L-shaped handle 18 is used to insert into the glass mounting seam 21 on the door sheet metal body 2. An auxiliary component 3 is installed at the bottom of the bottom shell 13; the auxiliary component 3 is used to prevent the vertical portion on one side of the n-shaped base plate 16 close to the inverted L-shaped handle 18 and the two L-shaped grippers 15 from causing impact and wear on the glass mounting seam 21 on the door sheet metal body 2 when they are manually inserted into the glass mounting seam 21; secondly, it is used to pre-position the n-shaped base plate 16 at the glass mounting seam 21 to prevent the n-shaped base plate 16 from moving forward and backward or left and right; thirdly, it is used to quickly remove the auxiliary component 3 from the glass mounting seam 21.

[0042] 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 grips 15, which can facilitate the two L-shaped grips 15 to rotate through the top rotating shaft 14; and the gear set 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 set transmission structure, so that when the push switch 17 is pressed, it can prompt the gear set transmission structure to drive the rotating shaft 14 to drive the two L-shaped grips 15 to rotate and lock the inner wall of the glass installation seam 21. When the push switch 17 is pressed again, its gear set transmission structure drives the rotating shaft 14 to drive the two L-shaped grips 15 to reverse and reset to a vertical state. All the above principles are existing technologies and will not be described in detail.

[0043] like Figures 2 to 10As shown, in order to enable the vertical portion on one side of the n-shaped bottom plate 16 close to the inverted L-shaped handle 18 and the two L-shaped grippers 15 to avoid impact and wear on the glass installation seam 21 on the door sheet metal body 2 when manually inserted into the glass installation seam 21, an auxiliary component 3 is provided, including a first U-shaped support frame 31 and a second U-shaped support frame 32. The first U-shaped support frame 31 and the second U-shaped support frame 32 are respectively fixed to the outer wall of the bottom shell 13 by two bolts. The middle of the two side walls of the first U-shaped support frame 31 are respectively integrally formed with a side baffle 33 and a guide plug plate 34 through a first reset spring piece 311. The bottom end of the side baffle 33 is provided with an arc-shaped avoidance portion 331. The vertical section of the guide plug plate 34 is a U-shaped structure. There are two symmetrically distributed inclined surfaces, and two symmetrically distributed first weakened grooves 341 are opened in the guide plug plate 34 near the two inclined surfaces. The middle part of the 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 opened on the side baffle 33 are both integrally formed with a first adapting spring piece 36, and the two symmetrically distributed through-grooves opened on both side walls of the guide plug plate 34 are also integrally formed with a second adapting spring piece 37. The shape of the first adapting spring piece 36 is the same as that of the second adapting spring piece 37, and both are arc-shaped bending structures.

[0044] Among them, two symmetrically distributed movable channels 342 are provided on both side walls of the guide plate 34. Figure 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 side baffles 33 respectively, effectively preventing the guide plug-in 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 side baffle 33 to follow the guide plug-in 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 to directly hit the edge of the inner surface of the door sheet metal body 2, playing a good protective role; the guide plug-in plate 34 cooperates with the four second adapter springs The arrangement of the pieces 37 enables the guide plug plate 34 to adapt to glass installation gaps 21 of different widths and facilitates pre-positioning for glass installation gaps 21 of different widths, so that the mechanical gripper body 1 can adapt to various types of car doors for grabbing action and has a wide range of applications; the four second adapting spring pieces 37 and the two second adapting spring pieces 37 make the guide plug plate 34 and the side baffles 33 more secure when they are installed on the n-shaped 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, makes the guide plug plate 34, before it is inserted into the glass installation gap 21, have its two side walls in an outwardly splayed inclined design, and the side baffles 33 will be 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.

[0045] like Figures 2 to 10As shown, in order to enable the guide plate 34 and the side baffle 33 to be quickly withdrawn from the glass installation gap 21 while the push switch 17 needs to be squeezed, two first reset springs 311 are provided, each of which is fixedly connected to a first transmission column 38 at the middle of both ends, and a second reset spring 35 is fixedly connected to a second transmission column 39 at the middle of both ends. A first V-shaped rod 382 is movably sleeved on the outer side of each first transmission column 38, and the first V-shaped rod 382 is fixedly connected 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, which is fixed to the outer wall of the second U-shaped support frame 32. The second V-shaped rod 313 is provided with a second inclined groove 314 adapted to the diameter of the second transmission column 39. 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. 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 fixed with the first lifting rod 315 and the second lifting rod 316 respectively. 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. The ends of the two transmission cross bars 310 away from the side baffle 33 are connected by the inverted L-shaped rod 3 17 is integrally formed with a same arc-shaped pressing plate 318. The top of the arc-shaped pressing plate 318 is fixed to the front side wall of the bottom shell 13 by two bolts. An avoidance groove 321 is provided in the middle position of the bottom of the arc-shaped pressing plate 318. Third weakening grooves 320 are provided at the connection points of the two ends of the bottom of the arc-shaped pressing plate 318. Second weakening grooves 319 are provided at the connection points of the top of the arc-shaped pressing plate 318. A pressing portion 322 is provided in the middle of the surface of the arc-shaped pressing plate 318. The pressing portion 322 is made of a circular elastic rubber material.

[0046] The widths of the first slanted groove 381, the second slanted groove 314, and the transmission channel 312 all need to be compatible with the diameters of the first transmission column 38 and the second transmission column 39. All components of the auxiliary assembly 3 can be made of ABS plastic, which can reduce manufacturing costs and is integrated into one piece for easy production.

[0047] When the finger presses the pressing portion 322, the bottom of the arc-shaped pressing plate 318 will move downward, and the setting of the avoidance groove 321 will prevent the inverted L-shaped handle 18 from blocking 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 curved surface of the arc-shaped pressing plate 318 is pressed and straightened, and can press the press switch 17 at the same time.

[0048] The present invention also provides a method for using multiple types of vehicle door grips, comprising the following steps:

[0049] Step 1: Manually hold the inverted L-shaped handle 18 and pull the bottom shell 13 downward to insert the vertical portion of the n-shaped bottom plate 16 near the inverted L-shaped handle 18 into the glass installation gap 21. With the help of the setting of the auxiliary component 3, the vertical portion of the n-shaped bottom plate 16 near the inverted L-shaped handle 18 and the two L-shaped grips 15 will not cause any impact on the glass installation gap 21 during the process of insertion;

[0050] Step 2: When removing the n-shaped base plate 16 and the two L-shaped grippers 15, you can hold the inverted L-shaped handle 18 and press the pressing portion 322 thereon with your fingers. At the same time, with the help of the setting of the auxiliary component 3, the top two 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 in a direction away from the first U-shaped support frame 31. The above coordinated operation, coupled with the setting of the auxiliary component 3 to guide the guide plug plate 34 and the side baffle 33 to deform, can make it possible to remove from the glass installation seam 21.

[0051] The working principle of the technical solution provided by the present invention is as follows:

[0052] The operator can hold the inverted L-shaped handle 18 and pull the mechanical gripper body 1 down 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 the 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 side baffle 33 actively avoids 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 without being easily The edge of the glass installation seam 21 is hit, which effectively improves the use efficiency of the mechanical gripper body 1 while protecting the outer surface paint surface of the door sheet metal body 2 from damage. In addition, when the vertical portion of the side of the n-type base plate 16 close to the inverted L-shaped handle 18 is inserted into the glass installation seam 21, it can make use of the elastic action of the first adapter spring 36 and the second adapter spring 37 to prompt the n-type base plate 16 to be pre-positioned at the glass installation seam 21.
