Description

Technical Field

[0001] The present invention relates to the technical field of part riveting, and particularly to a riveting nut riveting device for an automobile radiator condenser bracket. Background Art

[0002] During the automobile manufacturing process, the fixation and installation of the automobile radiator condenser are crucial links. To ensure that the automobile radiator condenser maintains a stable position during the operation of the automobile and can withstand the action of various forces, a reliable connection method is required to connect the automobile radiator condenser bracket to other structures. As a commonly used connection method, riveting nuts have the advantages of firm connection, high reliability, and easy installation, so they are widely used in the connection of automobile radiator condenser brackets.

[0003] Traditional riveting devices have certain limitations: When traditional riveting devices convey the automobile radiator condenser bracket, they often adopt simple conveyor belt or roller conveying methods. This conveying method is prone to causing the bracket to shift and shake, affecting the accuracy and quality of riveting. Moreover, during the riveting process, there is no effective limiting measure for the bracket, which is prone to warping, increasing the difficulty and risk of riveting.

[0004] When traditional riveting devices perform the feeding of riveting nuts, they usually adopt manual feeding or simple mechanical feeding methods. This feeding method is inefficient and difficult to meet the requirements of large-scale production. Moreover, problems such as nut dropping and inaccurate position are likely to occur during the feeding process, affecting the quality and efficiency of riveting.

[0005] There is a lack of effective coordination among the various components of traditional riveting devices. Manual coordination and operation are often required, increasing the complexity and difficulty of operation. Moreover, the actions of different components are not synchronized, which is prone to causing problems during the riveting process, affecting production efficiency and quality.

[0006] In summary, with the development of the automobile manufacturing industry, the requirements for production efficiency are getting higher and higher. The traditional manual riveting method is not only inefficient but also difficult to guarantee quality. Therefore, a riveting nut riveting device for an automobile radiator condenser bracket is needed, which can achieve efficient and precise riveting operations, improve production efficiency, and reduce production costs.

[0018] The beneficial effects of the rivet nut riveting device for a car water tank condenser bracket of the present invention are:

[0019] (1) The present invention has a stable conveying and clamping effect: the square steel bracket is placed in the conveying path and supported by the transmission roller, which ensures the stability of the conveying process; at the same time, the operation of the motor 1 causes the screw to rotate, driving the lifting plate to descend, thereby making all the L plates close to the upper surface of the square steel bracket, and the two cross plates are moved close to the front and rear sides of the square steel bracket through the gear cylinder transmission; the L plate contacts the top of the square steel bracket through the roller 1, the cross plate contacts the front and rear sides of the square steel bracket through the roller 2, and the transmission roller contacts and supports the bottom of the square steel bracket, so as to wrap and clamp the square steel bracket;

[0020] The all-round clamping method makes the square steel bracket more stable during transportation and riveting operations, avoiding the problem of inaccurate riveting caused by transportation deviation, and also preventing the square steel bracket from tilting during riveting operations due to the lack of limit.

[0021] (2) The present invention has the functions of automatic feeding and intermittent operation: the feeding mechanism realizes the automatic feeding of the rivet nut through the cooperation of the turntable, the second motor, the rotating shaft and other components. When the front clamping mouth is fed by the external feeding equipment to squeeze the two clamping claw inclined surfaces located in the front, the clamping claw is squeezed open, driving the corresponding arc plate 1 to slide, and the corresponding arc plate 2 to slide under the transmission of the spur gear, so that the two clamping claws at the rear move open, and the rivet nut located above the mounting hole loses its clamping and falls into the mounting hole. The operation of motor 2 moves the turntable, and the front clamp holding a new rivet nut rotates half a circle to above the empty mounting hole, while the clamp and material mouth that have lost the rivet nut rotate half a circle to the front to wait for feeding, thereby realizing cyclic and intermittent continuous operation and improving processing efficiency. In addition, when used in conjunction with the intermittently moved and transported square steel bracket, the mounting hole can be intermittently moved to the bottom of the material mouth and the rivet nut for assembly, and the riveting gun can also rivet the mounting hole with the assembled rivet nut, providing a reliable connection foundation for the subsequent fixation and installation of the automobile radiator condenser in the entire automobile structure.

[0034] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0035] Refer to Figures 1-9, An automobile radiator condenser bracket rivet nut riveting device, including a machine tool 1. There is a conveying channel 2 on the upper surface of the machine tool 1.

A plurality of through grooves 14 are opened at the opposite ends of the two cross plates 13. A plurality of vertical chutes 15 are opened on the upper surface of the machine tool 1. An L-shaped plate 16 is commonly arranged inside the vertical chute 15 and the through groove 14. Four vertical frames 17 are fixed on the lower surface inside the side groove 3. A toothed cylinder 18 is rotatably connected at the top of two adjacent vertical frames 17. A motor one 20 is fixed inside the bottom groove 10. The top end of the output shaft of the motor one 20 is fixed with a lead screw 21. The lead screw 21 is threadedly connected with the interior of the lifting plate 11. During use, the square steel bracket 5 is placed inside the conveying channel 2 and supported by the transmission rollers 4. The motor one 20 operates to rotate the lead screw 21, so that the lifting plate 11 drives all the L-shaped plates 16 to descend and move closer to the upper surface of the square steel bracket 5, and drives the two cross plates 13 to move closer to the front and rear sides of the square steel bracket 5 through the transmission of the toothed cylinder 18;

[0036] A number of rollers one 40 are rotatably connected to one end of the L-shaped plate 16 close to the square steel bracket 5. A number of rollers two 41 are rotatably connected to the opposite ends of the two cross plates 13. The cross plates 13 are in contact and fit with the front and rear sides of the square steel bracket 5 through the rollers two 41. The transmission rollers 4 are in contact and support the bottom of the square steel bracket 5. The L-shaped plate 16 is in contact with the top of the square steel bracket 5 through the rollers one 40 above, so as to realize the wrapping and clamping of the square steel bracket 5, making it more stable during conveying and riveting operations, avoiding conveying deviation, resulting in inaccurate riveting, and also avoiding the situation that the square steel bracket 5 warps during riveting operation due to lack of limit.

[0037] Refer to Figures 2-4 , Below the outer surface of the rotating shaft 27, a helical gear two 28 is fixed. In the middle of the transmission roller 4, a driving roller 22 is fixed. The front end of the driving roller 22 penetrates to the inner surface of the front side groove 3, and a helical gear one 24 is fixed at the front end of the driving roller 22 located behind the rotating shaft 27. The helical gear one 24 is meshed and connected with the helical gear two 28. The rear ends of a number of driving rollers 22 all penetrate to the interior of the side groove 3 located at the rear, and a transmission belt 23 is commonly arranged on the outer surface.

[0038] Refer to Figures 3-5, the number of vertical sliding grooves 15 is the same as that of the through grooves 14. The L-shaped plate 16 is slidably connected to the vertical sliding groove 15, and the toothed cylinder 18 is located below the cross plate 13;

[0039] A number of first toothed grooves 19 are provided on the lower surface of the cross plate 13 and the outer surface of the L-shaped plate 16. The cross plate 13 and the L-shaped plate 16 are both meshed and connected to the toothed cylinder 18 through the first toothed grooves 19, and the cross plate 13 and the L-shaped plate 16 are drivingly connected through the toothed cylinder 18.

[0040] Refer to Figures 6-9 , the feeding mechanism 7 includes a turntable 25. The turntable 25 is rotatably connected to the upper surface of the machine tool 1. A second motor 26 is fixed to the lower surface inside the side groove 3 at the front. The top of the output shaft of the second motor 26 is fixed with a rotating shaft 27. Feeding ports 29 are provided on the front and rear sides of the outer surface of the turntable 25. An annular inner groove 30 is provided inside the turntable 25. The inner groove 30 communicates with the two feeding ports 29. Rotating rods 32 are symmetrically and rotatably connected inside the inner groove 30. A spur gear 31 and a torsion spring 33 are sequentially arranged on the outer surface of the rotating rod 32 from bottom to top. The spur gear 31 is fixedly connected to the rotating rod 32. Two arc plates 34 and two arc plates 35 are slidably connected inside the inner groove 30. The arc plates 34 and the arc plates 35 are respectively located on both sides of the torsion spring 33. A number of second toothed grooves 38 are provided on the opposite sides of the arc plates 34 and the arc plates 35. The arc plates 34 and the arc plates 35 are both meshed and connected to the spur gear 31 through the second toothed grooves 38. Clamping claws 36 are fixed to the opposite ends of the two arc plates 34 and the opposite ends of the two arc plates 35. Clamping openings 37 are commonly provided at the opposite ends of the adjacent two clamping claws 36. The clamping openings 37 are adapted to the cylindrical part of the blind rivet nut 8, and the diameter of the clamping openings 37 is smaller than the diameter of the cap head of the blind rivet nut 8, so that it will not slide off under the limit of the cap head;

[0041] The blind rivet nut 8 is located above the rightmost mounting hole 6, and the blind rivet nut 8 is located inside the clamping opening 37 at the rear;

[0042] The outer sides of the opposite ends of the adjacent two clamping claws 36 are both bevel-shaped structures; when the new blind rivet nut 8 conveyed by the external feeding device presses the bevels of the two clamping claws 36 at the front in the front clamping opening 37, the clamping claws 36 will be squeezed open, driving the corresponding arc plates 34 to slide, and driving the corresponding arc plates 35 to slide under the transmission of the spur gear 31, so that the two clamping claws 36 at the rear move and open, so that the blind rivet nut 8 located above the mounting hole 6 loses its clamping and falls into the mounting hole 6. Under the operation of the second motor 26, the turntable 25 moves, and the new blind rivet nut 8 clamped in the front is rotated half a turn to above the empty mounting hole 6, and the clamping opening 37 and the feeding port 29 that have lost the blind rivet nut 8 are rotated half a turn to the front to wait for feeding, realizing cyclic and intermittent continuous operation, which can improve the processing efficiency;

[0043] When the turntable 25 rotates for feeding, the rotating rotating shaft 27 drives the corresponding transmission roller 22 to rotate through the second bevel gear 28 and the first bevel gear 24. Under the drive of the transmission belt 23, all the transmission rollers 4 move synchronously, enabling the square steel bracket 5 to move intermittently from left to right for transportation. It is used in combination with the feeding mechanism 7 for intermittent feeding, so that the mounting hole 6 can move intermittently to the material port 29 and under the rivet nut 8 for assembly work, and also enables the riveting gun 45 to perform riveting operations on the mounting hole 6 with the rivet nut 8 assembled.

[0044] Refer to Figure 9 , a ring groove 39 is formed at the bottom of the turntable 25. The height inside the ring groove 39 is higher than the height of the cap head of the rivet nut 8. When the rivet nut 8 is placed inside the mounting hole 6, its top cap head will be located on the surface of the square steel bracket 5. The design of the ring groove 39 ensures that the turntable 25 will not contact the cap head when rotating, without affecting subsequent operations.

[0045] Refer to Figures 1-3 , a vertical frame 42 is fixed to the upper right rear of the upper surface of the machine tool 1. A cylinder 43 is fixed inside the vertical frame 42. The top of the piston rod of the cylinder 43 is fixed with a lifting frame 44. A riveting gun 45 is arranged at the front end of the lifting frame 44. After the rivet nut 8 is placed into the mounting hole 6 of the square steel bracket 5 through the feeding mechanism 7 and moves to the lower part of the riveting gun 45 through the transmission roller 4, the cylinder 43 contracts to lower the lifting frame 44 and the riveting gun 45. The riveting head in the riveting gun 45 enters the rivet nut 8 for riveting operation, so that a plurality of rivet nuts 8 are riveted on the surface of the square steel bracket 5 serving as the bracket for the automotive radiator condenser, providing a connection basis for connection with other structures in subsequent processes to achieve the fixation and installation of the automotive radiator condenser in the entire automotive structure.

[0046] The above embodiments only represent several implementation modes of the present invention, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
