DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figure 1-10 As shown, the present invention provides a technical solution: an automobile component welding device, comprising a shell 1 with a hollow inner cavity and an opening on one side, and a welding robot 2 fixed in the inner cavity of the shell 1 and welding the automobile component. The welding robot 2 is an existing device, so it is not described in detail here. A bottom plate 3 located beside the welding robot 2 is fixed at the bottom of the inner cavity groove of the shell 1, and two supporting guide rails 4 arranged opposite to each other and having a cross-shaped cross-section are fixed on the bottom plate 3. The supporting guide rails 4 are provided with cross-shaped through holes 401, and each supporting guide rail 4 is slidably connected with a transverse slider 5 and a longitudinal slider 6. A transverse support plate 7 and a longitudinal support plate 8 for supporting the automobile component are respectively arranged between the two transverse sliders 5 and between the two longitudinal sliders 6. Adjacent transverse sliders 5 and longitudinal sliders 6 are connected by a connecting assembly 9, and a control assembly 10 for controlling the connecting assembly 9 to rotate to drive the transverse slider 5 and the longitudinal slider 6 to move is provided on the side of each supporting guide rail 4.

[0043] like Figure 1 and Figure 2 The device is placed in the inner cavity of the shell 1 as a whole. The shell 1 protects the staff and reduces the impact of welding sparks on the staff and the working environment. The shell 1 has an opening on one side. The staff disassembles and assembles the automobile parts on the support plate through the opening position, and provides power through the welding robot 2 to weld the automobile parts placed on the support plate. The control component 10 provides power to drive the connecting component 9 to rotate, thereby driving the transverse slider 5 and the longitudinal slider 6 to slide in the support guide rail 4, thereby realizing the position conversion of the transverse support plate 7 and the longitudinal support plate 8. When the longitudinal support plate 8 moves to the middle position of the support guide rail 4, the transverse support plate 7 moves to the position of the support guide rail 4 close to the opening on one side of the shell 1, which is convenient for the staff to disassemble and assemble the automobile parts on the transverse support plate 7. When the transverse support plate 7 moves to the middle position of the support guide rail 4, the longitudinal support plate 8 moves to the top position of the support guide rail 4. At this time, the staff disassembles and assembles the automobile parts on the longitudinal support plate 8, saving the time-consuming disassembly and assembly of automobile parts and improving work efficiency.

[0044] like Figure 1 and Figure 2 and Figure 3 and Figure 7 The connecting assembly 9 includes a connecting rod 901 arranged beside the supporting guide rail 4, and the transverse slider 5 and the longitudinal slider 6 in the supporting guide rail 4 are respectively arranged at both ends of the connecting rod 901 and are rotatably connected to the connecting rod 901. A follower gear 902 is fixed in the middle position of the connecting rod 901. The control assembly 10 includes a supporting seat 1001 fixed on the bottom plate 3 and located beside the supporting guide rail 4.

A short shaft is rotatably connected to the other supporting seat 1001, and the short shaft passes through the supporting seat 1001. One end of the short shaft passing through the supporting seat 1001 is coaxially fixed with the adjacent driving gear 1002, and the two driving gears 1002 are connected through a transmission assembly.

[0045] like Figure 1 and Figure 2 and Figure 3The transmission assembly includes an A synchronous wheel 1004 coaxially fixed to the other output shaft of the double-headed motor 1003, a C synchronous wheel 1008 coaxially fixed to the other end of the short shaft passing through the support seat 1001, and two relatively arranged fixed seats 1005 are fixed on the bottom plate 3, and the fixed seats 1005 are respectively rotatably connected to the B synchronous wheel 1006 adjacent to the A synchronous wheel 1004 and the D synchronous wheel 1007 adjacent to the C synchronous wheel 1008, and the outer sleeves of the A synchronous wheel 1004 and the B synchronous wheel 1006 are provided with the A synchronous wheel 1004 and the B synchronous wheel 1006. A first transmission belt 1009 is adapted to the synchronous wheel 1006, and a second transmission belt 1010 adapted to the C synchronous wheel 1008 and the D synchronous wheel 1007 is provided on the outer cover of the C synchronous wheel 1008 and the D synchronous wheel 1007. A transmission rod 1011 is arranged between the two fixed seats 1005, and both ends of the transmission rod 1011 are respectively passed through adjacent fixed seats 1005 and are rotatably connected with the fixed seats 1005. The end of the transmission rod 1011 passing through the fixed seat 1005 is coaxially fixed to the adjacent B synchronous wheel 1006 and the D synchronous wheel 1007.

[0046] like Figure 1 and Figure 2 and Figure 3 and Figure 7 The double-headed motor 1003 provides power to drive the A synchronous wheel 1004 coaxially fixed to one of the output shafts of the double-headed motor 1003 to rotate. The rotation of the A synchronous wheel 1004 will drive the first transmission belt 1009 sleeved outside the A synchronous wheel 1004 and adapted to the A synchronous wheel 1004 to rotate. The rotation of the first transmission belt 1009 will drive the B synchronous wheel 1006 adapted to the first transmission belt 1009 to rotate. The rotation of the B synchronous wheel 1006 will drive the transmission rod 1011 coaxially fixed to the B synchronous wheel 1006 to rotate. The rotation of the transmission rod 1011 will drive the transmission The D synchronous wheel 1007 coaxially fixed with the rod 1011 rotates, and the rotation of the D synchronous wheel 1007 will drive the second transmission belt 1010 sleeved on the D synchronous wheel 1007 to rotate, and the rotation of the second transmission belt 1010 will drive the C synchronous wheel 1008 adapted to the second transmission belt 1010 to rotate, and the rotation of the C synchronous wheel 1008 will drive the short shaft coaxially fixed with the C synchronous wheel 1008 to rotate, and the rotation of the short shaft will drive the driving gear 1002 coaxially fixed with the short shaft to rotate, and at the same time, the double-headed motor 1003 will drive the driving gear 1002 fixed to its other output shaft to rotate.

[0047] like Figure 1 and Figure 2 and Figure 3 and Figure 7The rotation of the two driving gears 1002 will drive the follower gear 902 meshing with the driving gear 1002 to rotate, and the rotation of the follower gear 902 will drive the connecting rod 901 fixed to the follower gear 902 to rotate, and at the same time drive the transverse slider 5 and the longitudinal slider 6 rotatably connected to the connecting rod 901 to slide in the support guide rail 4. The sliding of the transverse slider 5 and the longitudinal slider 6 in the support guide rail 4 will drive the transverse support plate 7 and the longitudinal support plate 8 to move in the cross guide rail, the transverse support plate 7 moves along the transverse direction of the support guide rail 4, and the longitudinal support plate 8 moves along the longitudinal direction of the support guide rail 4, thereby realizing the position conversion of the transverse support plate 7 and the longitudinal support plate 8.

[0048] like Figure 1 and Figure 2 and Figure 3 and Figure 7 and Figure 8 A longitudinal flipping assembly 11 is provided on the support guide rail 4 for controlling the flipping of the longitudinal support plate 8 to further improve work efficiency. The longitudinal flipping assembly 11 includes a connecting shaft 1101 which is arranged on the longitudinal slider 6 and is rotatably connected to the longitudinal slider 6. The connecting shaft 1101 passes through the support guide rail 4 through a cross-shaped through hole 401. One end of the connecting shaft 1101 passing through the support guide rail 4 is fixedly connected to the longitudinal support plate 8. A rocker arm 1102 with a V-shaped cross section is nested outside the connecting shaft 1101 and is fixed to the connecting shaft 1101 and is located between the support guide rail 4 and the longitudinal support plate 8. Pin rods 1103 are fixed at both ends of the rocker arm 1102. A limiting assembly 12 is provided on the side of the support guide rail 4 for cooperating with the pin rod 1103 to realize the flipping of the support plate.

[0049] like Figure 1 and Figure 2 and Figure 3 and Figure 8 The limiting assembly 12 includes a slide rail 1201 fixed on the base plate 3, and a limiting plate 1202 with a cross-shaped cross section and adapted to the pin rod 1103 is slidably connected to the slide rail 1201. A groove 1203 is provided on the top of the limiting plate 1202, and a limiting block 1204 with a triangular cross section that is adapted to the pin rod 1103 is integrally formed in the middle position of the bottom of the groove of the limiting plate 1202. The cross section of the limiting plate 1202 is cross-shaped so as not to affect the horizontal movement of the transverse support plate 7.

[0050] like Figure 7The longitudinal slider 6 and the connecting rod 901 are passed through the end of the connecting shaft 1101 away from the longitudinal support plate 8, and the connecting shaft 1101 is rotatably connected to the connecting rod 901. A positioning rod 1104 is fixed to the end of the connecting shaft 1101 passing through the connecting rod 901, and the center line of the positioning rod 1104 is perpendicular to the center line of the connecting shaft 1101. A positioning pin 1105 is also fixed on the connecting rod 901, and the end of the positioning rod 1104 away from the connecting shaft 1101 is fixedly connected to the positioning pin 1105 by a spring 1106. Two dead stops 1107 arranged opposite to each other and located below the positioning rod 1104 are fixed on the connecting rod 901, and the dead stop 1107 conflicts with the positioning rod 1104.

[0051] like Figure 1 and Figure 2 and Figure 3 and Figure 7 and Figure 8 and Fig. 9 When the longitudinal slider 6 moves up along the longitudinal direction of the support guide rail 4 as the connecting rod 901 rotates, the pin 1103 moves to contact the limit plate 1202, and the limit plate 1202 presses one of the pins 1103 located on the upper side. At this time, the longitudinal slider 6 continues to move upward, and the rocker arm 1102 rotates, driving the connecting shaft 1101 fixed to the rocker arm 1102 to rotate. The rotation of the connecting shaft 1101 will drive the positioning rod 1104 fixed to the connecting shaft 1101 to rotate, and the power is provided by the spring 1106 to drive the positioning rod 1104 to rotate 180 degrees until the positioning rod 1104 rotates to conflict with another dead stop 1107. At this time, the rotation of the connecting shaft 1101 will drive the support plate fixed to the connecting shaft 1101 to flip 180 degrees.

[0052] like Figure 1 and Figure 2 and Figure 3 and Figure 7 and Figure 8 and Fig. 9 , and then the motor provides power to drive the flipped support plate to move downward along the longitudinal direction on the support guide rail 4. The flipped support plate, the longitudinal slider 6 and the rocker arm 1102 move downward, and the spring 1106 provides power to limit the rocker arm 1102. The rocker arm 1102 will not be displaced during the movement. The rocker arm 1102 moves downward until it contacts the outer wall of the limit block 1204. Since the outer wall of the limit block 1204 is an inclined surface, the downward movement of the rocker arm 1102 will push the limit block 1204 to move, thereby driving the limit plate 1202 fixed to the limit block 1204 to move on the slide rail 1201, so that when the rocker arm 1102 moves up again, it will contact the other side of the limit plate 1202 and continue to flip.

[0053] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 7 A lateral flipping assembly 13 is provided on the support guide rail 4 to control the flipping of the lateral support plate 7 to further improve the working efficiency. The lateral flipping assembly 13 includes a mounting groove 1301 opened at the end of the connecting rod 901 away from the connecting shaft 1101. By setting the mounting groove 1301, the movable rod 1303 and the roller 1304 located in the mounting groove 1301 do not affect the movement of the driving gear 1002 and the follower gear 902. A mounting shaft 1302 is provided in the mounting groove 1301, and the mounting shaft 1302 passes through the connecting rod 901 and the lateral slider 5 and is rotatably connected to the connecting rod 901 and the lateral slider 5. One end of the mounting shaft 1302 passing through the lateral slider 5 is fixedly connected to the lateral support plate 7, and the other end of the mounting shaft 1302 passing through the connecting rod 901 is fixed with a movable rod 1303, and the movable rod 1303 is rotatably connected to the roller 1304 at one end away from the connecting rod 901.

[0054] like Figure 4 A guide plate 1305 is fixed to the end of the support rail 4 away from the welding robot 2 , and a guide groove 1306 adapted to the roller 1304 and slidably connected to the roller 1304 is provided in the guide plate 1305 .

[0055] like Figure 4 and Figure 7 When the transverse slider 5 moves toward the side of the guide plate 1305, the roller 1304 is stuck in the guide groove 1306. As the transverse slider 5 moves, the roller 1304 slides in the guide groove 1306, which will drive the movable rod 1303 movably connected to the roller 1304 to rotate. The rotation of the movable rod 1303 will drive the installation shaft 1302 fixed to the movable rod 1303 to rotate. The rotation of the installation shaft 1302 will drive the transverse support plate 7 fixed to the installation shaft 1302 to flip.

[0056] like Figure 1 and Figure 2 and Figure 3 and Fig.10 A plurality of threaded holes 14 are provided on the transverse support plate 7 and the longitudinal support plate 8. A plurality of quick clamps 15 for fixing automobile parts are fixed on the upper and lower sides of the transverse support plate 7 and the longitudinal support plate 8 by screws, so as to facilitate the fixing of automobile parts of different sizes. The quick clamps 15 are existing equipment, so they will not be described in detail here.

[0057] like Figure 1 and Figure 2 and Figure 3 and Figure 5 A support assembly 16 is fixed at the middle position of the bottom plate 3 to support the transverse support plate 7 or the longitudinal support plate 8 being welded.

[0058] like Figure 5The support assembly 16 includes a fixed frame 1601 fixed at the middle position of the base plate 3 and located between the two support guide rails 4, and two electric push rods 1602 are fixed on the fixed frame 1601. The extended ends of the electric push rods 1602 are fixed with square support frames 1603 adapted to the horizontal support plates 7 and the longitudinal support plates 8. Four telescopic rods that guide the movement of the square support frames 1603 are also fixed at the four end corners of the fixed frame 1601.

[0059] like Figure 5 In the initial state, the square support frame 1603 is in conflict with the upper surface of the fixing frame 1601. When the longitudinal support plate 8 moves to the bottom, it does not conflict with the square support frame 1603. When the longitudinal support plate 8 or the transverse support plate 7 moves to the middle position of the support guide rail 4, the electric push rod 1602 provides power to drive the square support frame 1603 to move upward, and the telescopic rod guides the movement of the square support frame 1603. The square support frame 1603 moves up to a suitable position to support the transverse support plate 7 or the longitudinal support plate 8 without affecting the lower automobile parts of the transverse support plate 7 or the longitudinal support plate 8.

[0060] like Figure 1 and Figure 2 Two inclined cylinders 17 are also fixed in the inner cavity of the shell 1. Baffles 18 are fixed at the extended ends of the two cylinders 17. The baffles 18 are arranged obliquely and are slidably connected to the shell 1. When the transverse support plate 7 or the longitudinal support plate 8 moves to the middle position of the support guide rail 4, the cylinder 17 provides power to drive the baffle 18 to move and make the baffle 18 above the transverse support plate 7 or the longitudinal support plate 8 located in the middle position, which does not affect the welding work of the welding robot 2 and reduces the impact of welding sparks on the staff who disassemble and assemble automobile parts.

[0061] When in use, the power is turned on, the switch is turned on, and the staff selects a suitable number of quick clips 15 according to the size of the automobile parts, and fixes the quick clips 15 to suitable positions on the transverse support plate 7 and the longitudinal support plate 8 by screws, and fixes the automobile parts by the quick clips 15;

[0062] The staff turns on the double-headed motor 1003, and the double-headed motor 1003 provides power to drive the A synchronous wheel 1004 coaxially fixed with one of the output shafts of the double-headed motor 1003 to rotate, and transmits power through the A synchronous wheel 1004, the B synchronous wheel 1006, the first transmission belt 1009, the transmission rod 1011, the D synchronous wheel 1007, the second transmission belt 1010 and the C synchronous wheel 1008, so as to drive the short shaft coaxially fixed with the C synchronous wheel 1008 to rotate, thereby driving the driving gear 1002 coaxially fixed with the short shaft to rotate, and at the same time, the other output shaft of the double-headed motor 1003 also drives the driving gear 1002 coaxially fixed with it to rotate;

[0063] The rotation of the two driving gears 1002 will drive the driven gear 902 meshing with the driving gear 1002 to rotate, and the rotation of the driven gear 902 will drive the connecting rod 901 fixed to the driven gear 902 to rotate, and the rotation of the connecting rod 901 will drive the transverse slider 5 and the longitudinal slider 6 rotatably connected to the connecting rod 901 to move on the supporting guide rail 4;

[0064] The movement of the transverse slider 5 will drive the installation shaft 1302 rotatably connected to the transverse slider 5 to move along the transverse direction of the support rail 4. The movement of the installation shaft 1302 will drive the transverse support plate 7 fixed to the installation shaft 1302 to move along the transverse direction of the support rail 4. The transverse support plate 7 is slidably connected to the limit plate 1202. A connection groove is provided on the side of the limit plate 1202 close to the guide plate 1305, which does not affect the flipping of the transverse support plate 7.

[0065] The movement of the longitudinal slider 6 drives the connecting shaft 1101 rotatably connected to the longitudinal slider 6 to move, thereby driving the longitudinal support plate 8 fixed to the connecting shaft 1101 to move along the longitudinal direction of the support rail 4. Through the action of the spring 1106, the longitudinal support plate 8 will not move in the vertical direction and will not turn over when encountering the baffle 18.

[0066] When the transverse support plate 7 moves to the middle position of the support rail 4, the transverse support plate 7 is located at the top or bottom of the support rail 4, and when the longitudinal support plate 8 moves to the middle position of the support rail 4, the transverse support plate 7 is located at the end of the support rail 4 close to the welding robot 2 or away from the welding robot 2;

[0067] Then, the electric push rod 1602 is turned on, and the square support frame 1603 is driven to move upward by the power provided by the electric push rod 1602. The square support frame 1603 moves upward to below the transverse support plate 7 or the longitudinal support plate 8 located in the middle position and supports the transverse support plate 7 or the longitudinal support plate 8, so as to reduce the possibility of the transverse support plate 7 or the longitudinal support plate 8 turning over during the welding process without affecting the automobile parts under the transverse support plate 7 or the longitudinal support plate 8.

[0068] At this time, the automobile parts on the transverse support plate 7 or the longitudinal support plate 8 located in the middle position are welded by the welding robot 2;

[0069] When the longitudinal support plate 8 is in the middle position, the transverse support plate 7 moves toward the side away from the welding robot 2. When the roller 1304 has not yet been inserted into the guide groove 1306, the double-headed motor 1003 is turned off, and the automobile parts on the transverse support plate 7 are disassembled and assembled. The welded automobile parts are removed and the automobile parts to be welded are installed. The disassembly and assembly can be done manually or by a manipulator. Then the double-headed motor 1003 is turned on, the transverse slider 5 continues to move, and the roller 1304 moves and is inserted into the guide groove 1306. As the transverse slider 5 moves, the roller 1304 slides in the guide groove 1306, which will drive the movable rod 1303 movably connected to the roller 1304 to rotate. The rotation of the movable rod 1303 will drive the installation shaft 1302 fixed to the movable rod 1303 to rotate. The rotation of the installation shaft 1302 will drive the transverse support plate 7 fixed to the installation shaft 1302 to flip 180 degrees, and then the automobile parts on the flipped transverse support plate 7 are disassembled and assembled.

[0070] When the horizontal support plate 7 is in the middle position, the longitudinal support plate 8 moves toward the top of the support rail 4. When the pin rod 1103 on the upper side has not yet contacted the top of the limit plate 1202, the double-headed motor 1003 is turned off, and the staff stands on the ladder to disassemble and assemble the automobile parts on the longitudinal support plate 8;

[0071] Then the double-headed motor 1003 is turned on, and the longitudinal slide block 6 continues to move upward until the pin rod 1103 on the upper side contacts one side of the slot top of the limit plate 1202. The pin rod 1103 on the upper side rotates under the pressure of the limit plate 1202, driving the swing rod 1102 and the connecting shaft 1101 fixed to the swing rod 1102 to rotate 180 degrees, and the positioning rod 1104 is driven to rotate 180 degrees by the spring 1106, until the positioning rod 1104 rotates to contact with another dead stop 1107. At this time, the staff disassembles and assembles the automobile parts on the flipped longitudinal support plate 8;

[0072] When the longitudinal support plate 8 moves down to the bottom of the support rail 4, the pin rod 1103 located on the lower side contacts the inclined surface of the limit block 1204, pushing the limit block 1204 to move, thereby driving the limit plate 1202 fixed to the limit block 1204 to slide on the slide rail 1201, so that the pin rod 1103 located on the upper side contacts the other side of the limit rod when moving up again to achieve flipping;

[0073] When the longitudinal support plate 8 moves upward and has not yet collided with the limit plate 1202, and the transverse support plate 7 moves toward the end away from the welding robot 2 and has not yet collided with the guide plate 1305, the cylinder 17 is opened at this time, and the power is provided by the cylinder 17 to drive the baffle 18 to move and make the baffle 18 move to the transverse support plate 7 or the longitudinal support plate 8 located in the middle position. A ranging sensor is provided on the outer shell. When the baffle 18 moves to a suitable position, the welding robot 2 performs welding work. The baffle 18 does not affect the welding work of the welding robot 2, while reducing the impact of welding sparks on the staff who disassemble and assemble automobile parts. Repeat the above operations. This is the use process of the automobile parts welding equipment. At the same time, the contents not described in detail in this manual belong to the existing technology known to professional and technical personnel in this field.
