Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and particularly relates to a follow-up mechanism for an automobile production line. Background Art

[0002] On the automobile production line, when the vehicle pallet or body passes by, it generates downward pressure on the encoder rubber wheel. When the vehicle or pallet moves in the opposite direction, the force on the encoder will increase, which will reduce the service life of the encoder, increase the failure rate when the synchronization solution is applied, and increase the risk of line stoppage. In order to avoid damage to the encoder, the assembled spring can only be adjusted according to the actual working conditions, but this approach also has the dilemma of limiting the flexibility of the production line and affecting the production efficiency of the production line. Therefore, it is necessary to design a follow-up mechanism for the automobile production line so that the movement direction of the vehicle or pallet no longer affects the service life of the encoder. Summary of the invention

[0003] The utility model provides a follow-up mechanism for an automobile production line to solve the technical problems existing in the known technology. The mechanism can keep the vehicle pallet or body moving forward or backward, and keep the encoder under force when pressed down, so as to avoid excessive force on the encoder when the vehicle moves backward when installed obliquely, thereby reducing the service life.

[0004] The utility model includes the following technical solutions:

[0005] A follow-up mechanism for an automobile production line includes an encoder connecting plate, a rotating shaft and a spring; the encoder is fixedly mounted on one end of the encoder connecting plate, and the other end is hinged to a fixed rotating shaft; a spring is fixedly mounted in the middle of the encoder connecting plate, which is compressed downward when subjected to force. When the encoder is subjected to downward pressure, it drives the encoder connecting plate to rotate around the rotating shaft, and the encoder connecting plate compresses the spring downward; after the vehicle or pallet passes, the elastic force of the spring is greater than the downward pressure, and the spring restores its length in the natural state, driving the encoder connecting plate and the encoder to move upward and reset.

[0006] Furthermore, the spring is sleeved on a guide rod in the middle of the spring guide shaft.

[0007] Furthermore, the upper portion of the spring guide shaft is fixedly mounted on the encoder connecting plate, and the middle portion of the guide rod is movably connected to the fixing member.

[0008] Furthermore, a mounting block is provided on the upper portion of the guide rod, and the mounting block is inserted into the mounting hole in the middle of the encoder connecting plate from one side and is tightened and fixed with bolts from the other side of the encoder connecting plate.

[0009] Furthermore, a limiting bolt is provided at the lower portion of the guide rod, and the limiting bolt is located below the fixing member to prevent the guide rod from being lifted too high when the spring is reset.

[0010] Furthermore, the fixing member is L-shaped, a rotating shaft is fixedly installed on the vertical side of the fixing member, and a guide rod is movably installed on the horizontal side.

[0011] Furthermore, the guide rod is movably mounted in a mounting groove arranged along a horizontal direction on the horizontal edge.

[0012] Furthermore, the width of the mounting groove is greater than or equal to the diameter of the guide rod and smaller than the outer diameter of the spring.

[0013] Furthermore, the fixing member is fixed on the ground via a mounting frame.

[0014] Furthermore, the encoder and the encoder connecting plate are fixedly connected by bolts, and there is no relative movement between the two.

[0015] The utility model has the following advantages and positive effects:

[0016] 1. The utility model provides an encoder connecting plate with a reset structure so that when a vehicle or a pallet generates downward pressure on the rubber wheel connected to the encoder, the encoder can rotate with the encoder connecting plate, thereby preventing the encoder from being subjected to excessive force and shortening the service life of the encoder.

[0017] 2. After using the utility model, the encoder is subjected to uniform force when the vehicle or pallet moves forward or backward in two directions, which reduces the failure rate when applying the synchronization solution, reduces the risk of line stoppage, and improves the overall utilization rate of the equipment.

[0023] In order to further disclose the content, features and effects of the invention, the following examples are given and described in detail with reference to the accompanying drawings.

[0024] Example: See attached Figure 1-4 A follow-up mechanism for an automobile production line includes an encoder connecting plate 2, a rotating shaft 3 and a spring 6; the encoder connecting plate 2 has an encoder 1 fixedly mounted on one end and is hinged to a rotating shaft 3 at a fixed position on the other end; a spring 6 which is compressed downward after being subjected to force is fixedly mounted in the middle of the encoder connecting plate 2. The encoder 1 and the encoder connecting plate 2 are fixedly connected by bolts, and there is no relative movement between the two. The encoder connecting plate 2 is installed between the encoder 1 and the rubber wheel 10.

[0025] The spring 6 is sleeved on the guide rod 501 in the middle of the spring guide shaft 5. The upper part of the spring guide shaft 5 is fixed on the encoder connecting plate 2, and the middle part of the guide rod 501 is movably connected to the fixing member 4. The upper part of the guide rod 501 is provided with a mounting block 502, such as Figure 3 As shown, the mounting block 502 is inserted into the mounting hole in the middle of the encoder connecting plate 2 from one side and is fastened with bolts from the other side of the encoder connecting plate 2. A limit bolt 503 is provided at the lower part of the guide rod 501, and the limit bolt 503 is located below the fixing part to prevent the guide rod 501 from being lifted too high when the spring 6 is reset.

[0026] The fixing member 4 is L-shaped, and the rotating shaft 3 is fixedly installed on the vertical side of the fixing member 4, and the guide rod 501 is movably installed on the horizontal side. In this example, the fixing member 4 is a connection reference member, and non-standard parts can also be used according to the production line conditions. The fixing member 4 is fixed on the ground through the mounting frame 8. The guide rod 501 is movably installed in an oblong mounting groove 401 set in the horizontal direction on the horizontal side. The width of the mounting groove 401 is greater than or equal to the diameter of the guide rod 501, and less than the maximum outer diameter of the spring 6.

[0027] Working principle: When the encoder 1 is subjected to downward pressure, it drives the encoder connecting plate 2 to rotate clockwise around the rotating shaft 3 (as in this example). Figure 2 If it is installed in the same direction, it rotates clockwise; if it is installed in a mirror direction, it rotates counterclockwise). The encoder connecting plate 2 drives the spring guide shaft 5 to move downward to compress the spring 6 downward, and the protruding length of the guide rod 501 under the fixing part 4 increases. While the spring guide shaft 5 moves downward, it also moves horizontally to the left along the installation slot 401; after the vehicle or pallet 7 passes, the elastic force of the spring 6 is greater than the downward pressure, and the spring 6 restores its length in the natural state along the guide rod 501, driving the encoder connecting plate 2 and the encoder 1 to move up and reset. During the reset process, the encoder connecting plate 2 rotates counterclockwise and drives the spring guide shaft 5 back to the initial position.

[0028] Although the preferred embodiments of the utility model are described above, the utility model is not limited to the above specific embodiments, which are merely illustrative and not restrictive. Under the enlightenment of the utility model, ordinary technicians in this field can make many forms without departing from the purpose of the utility model and the scope of protection of the claims. All of these belong to the protection scope of the utility model.
