Description

Technical Field

[0001] The utility model relates to the technical field of spring preparation, in particular to a material receiving and placing device for a tailgate spring and a spring machine. Background Art

[0002] The spring used in the car tailgate (hereinafter referred to as the tailgate spring) is a long spring with a large aspect ratio (ratio of length to diameter), which has the characteristics of large length and insufficient rigidity. When using a spring machine to prepare a tailgate spring, the following problems usually occur: the tailgate spring just wound out will tilt upward at a certain angle, and as the wound length becomes longer and longer, the tailgate spring has a tendency to droop downward at the end away from the spring machine due to its own gravity and lack of support, causing the tailgate spring to deform.

[0003] A Chinese patent with announcement number CN216176250U discloses a material receiving mechanism for a long spring and a spring machine, and further discloses that the material receiving mechanism for the long spring includes: a bracket, a material receiving trough and a first cylinder, the material receiving trough is hinged at one end of the bracket facing the spring machine body, the first cylinder is connected to the bracket, and the piston rod of the first cylinder is connected to the material receiving trough, the first cylinder is used to drive the material receiving trough to move in a direction not parallel to the horizontal so that the material receiving trough can tilt upward, and the two ends of the material receiving trough are rotatably connected to the support rod through a pin shaft, and the material receiving mechanism for the long spring also includes a second cylinder, the cylinder body of the second cylinder is connected to the support rod, and the piston rod of the second cylinder is used to connect to the material receiving trough to drive the material receiving trough to rotate.

[0004] The above-mentioned material receiving mechanism can solve the problem that the tailgate spring is deformed due to the end away from the spring drooping downward, but each time the material receiving chute rotates to discharge materials, the tailgate spring falls to the same position in the material box. Due to the large length of the tailgate spring, it cannot roll as flexibly to other places in the material box as a short spring. On the contrary, due to its excessive length, it is stuck by other materials during the rolling process. As a result, materials quickly accumulate at the position where the spring falls, and personnel need to frequently clean up the materials at this position. Utility Model Content

[0026] In addition, the terms "first", "second", etc. are only used to distinguish in description and have no special meaning.

[0027] like Figure 1 As shown, the spring machine of this embodiment includes a spring machine body (not shown in the figure) and a material receiving and placing device for the tailgate spring arranged at its output end. The material receiving and placing device for the tailgate spring can receive the tailgate spring formed from the spring machine body and automatically place it in a material box.

[0028] like Figure 1 and Figure 2 As shown, the material receiving and placing device for the tailgate spring of this embodiment mainly includes: a bracket 1, a first material receiving trough 2, a first cylinder 3, a second cylinder 4, a second material receiving trough 5, a linear drive mechanism 6, a third cylinder and a material box. Among them, one end of the first material receiving trough 2 facing the spring machine body is hinged on the bracket 1, and the end of the first material receiving trough 2 away from the spring machine body is connected to the piston rod of the first cylinder 3; the main body of the first cylinder 3 and the main body of the second cylinder 4 are respectively connected to the bracket 1, and the first cylinder 3 is used to drive the end of the first material receiving trough 2 away from the spring machine body to move in the vertical direction, so that the tailgate spring can be supported by the first material receiving trough 2 when it tilts upward to avoid deformation, and the piston rod of the second cylinder 4 is connected to the first material receiving trough 2, and is used to drive the first material receiving trough 2 to rotate to transfer the tailgate spring to the second material receiving trough 5. The linear drive mechanism 6 is connected to the bracket 1, and the linear drive mechanism 6 is used to drive the second material receiving trough 5 connected thereto to move in the horizontal direction. The third cylinder is connected to the linear drive mechanism 6, and is used to drive the second receiving trough 5 to rotate, so that the tailgate spring falls into the material box within the travel range of the second receiving trough 5. The first cylinder 3 of this embodiment is a non-inductive magnetic cylinder.

[0029] Specifically, the material box has a length direction and a width direction, and its length direction is parallel to the axial direction of the tailgate spring, or in other words, the length direction of the material box is parallel to the length direction of the second material receiving trough 5. The linear drive mechanism 6 is used to drive the second material receiving trough 5 to move along the width direction of the material box so that the tailgate spring can fall at different positions in the width direction of the material box to avoid the phenomenon of material piling at a certain position in the width direction of the material box.

[0030] Specifically, Figure 1 As shown, the bracket 1 of this embodiment is generally in the shape of a cuboid, and includes a first side frame 11 and a second side frame 12 arranged opposite to each other. The first material receiving trough 2 is hinged to the first side frame 11, the linear drive mechanism 6 is located on a side of the first material receiving trough 2 close to the second side frame 12, and the material box is located below the linear drive mechanism 6.

[0031] like Figure 3 and Figure 4As shown, the linear drive mechanism 6 of this embodiment includes a first conveyor belt 611, a first gear 621, a second gear 622, a transmission shaft 64, a motor 65, a connection seat 66 and a support rod 67. Among them, one end of the first conveyor belt 611 is connected to the bracket 1 through the first gear 621, and the other end of the first conveyor belt 611 is connected to the transmission shaft 64 through the second gear 622. In order to ensure the stability of the movement of the transmission shaft 64, it is preferred that the transmission shaft 64 can be rotatably connected to the second side frame 12 of the bracket 1. A third gear 63 is provided on the transmission shaft 64, and a fourth gear is connected to the output shaft of the motor 65. The third gear 63 and the fourth gear are connected through the second conveyor belt 612. The support rod 67 is fixedly connected to the first conveyor belt 611 through the connection seat 66, one end of the second receiving trough 5 is hinged to the support rod 67, and the other end is hinged to the output shaft of the third cylinder, and the cylinder body of the third cylinder is fixedly connected to the support rod 67. By adopting the above scheme, when the second material receiving trough 5 receives the tailgate spring from the first material receiving trough 2, the motor 65 drives the first conveyor belt 611 to rotate, thereby driving the support rod 67 and the second material receiving trough 5 thereon to move along the width direction of the material box. After the second material receiving trough 5 moves to the preset position, the third cylinder drives the second material receiving trough 5 to rotate so that the tailgate spring falls into the material box.

[0032] In order to improve the operating stability of the support rod 67 , the number of the first conveyor belts 611 can be multiple, such as 2 or 3, and correspondingly, the number of the first gear 621 and the second gear 622 is also multiple.

[0033] like Figure 3 and Figure 4 As shown, the linear drive mechanism 6 also includes a guide rod 68, both ends of which are connected to the bracket 1, and the guide rod 68 is inserted into the connecting seat 66, and the two are fixedly connected. The guide rod 68 can improve the running accuracy of the support rod 67 and further improve the running stability of the support rod 67.

[0034] like Figure 3 As shown, the linear drive mechanism 6 may further include a linear guide rail 691, a slide seat 692 and a fourth cylinder 693. The linear guide rail 691 is connected to the above-mentioned connection seat 66, the second material receiving trough 5 is slidably connected to the linear guide rail 691 through the slide seat 692, the cylinder body of the fourth cylinder 693 is connected to the linear guide rail 691, and the piston rod of the fourth cylinder 693 is connected to the slide seat 692. With the above solution, the fourth cylinder 693 can drive the second material receiving trough 5 to move along the length direction of the material box to align with the first material receiving trough 2, thereby ensuring that the tailgate spring transferred from the first material receiving trough 2 can completely fall into the second material receiving trough 5.

[0035] The material box is located between the first side frame 11 and the second side frame 12 of the bracket 1 , ensuring that the material box can be located below the linear drive mechanism 6 and within the travel range of the second material receiving trough 5 .

[0036] To sum up, the working process of the spring machine of this embodiment is as follows: the tailgate spring wound out from the spring machine body is received by the first material receiving trough 2. During the forming process of the tailgate spring, the first cylinder 3 drives the first material receiving trough 2 to move upward in the vertical direction so that the upward inclined end of the tailgate spring can be supported by the first material receiving trough 2 to avoid deformation; after the forming of the tailgate spring is completed, the second cylinder 4 drives the first material receiving trough 2 to rotate toward the second material receiving trough 5 so that the tailgate spring falls into the second material receiving trough 5. At the same time, the fourth cylinder 693 drives the second material receiving trough 5 to move along the length direction of the material box to receive the tailgate spring from the first material receiving trough 2; after the second material receiving trough 5 receives the tailgate spring, the piston rod of the fourth cylinder 693 retracts, and the motor 65 drives the first conveyor belt 611 to drive the second material receiving trough 5 to move along the width direction of the material box to a preset position. Then, the third cylinder drives the second material receiving trough 5 to rotate so that the tailgate spring falls into the material box.

The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope.
