[0002] The tail frame welding fixture for seeders is an indispensable piece of equipment in the manufacturing process of seeders. It can accurately and quickly position and fix the various components of the tail frame for welding operations. However, most existing tail frame welding fixtures require workers to place the various components of the tail frame onto the welding fixture in sequence and then screw multiple screws into the positioning holes of each component to fix the tail frame to the welding fixture. After welding, the screws must be unscrewed to remove the welded tail frame, which is time-consuming, labor-intensive, and inefficient. Therefore, we propose a tail frame welding fixture for seeders that can effectively solve the above problems. Utility Model Content

Both ends of the threaded rod penetrate the interior of the fixed plate, and the threaded rod and the fixed plate are threadedly connected. The threaded rod and the hole positioning core are positioned correspondingly. A retaining plate is sleeved on the outer side of the opposite ends of the two threaded rods.
[0008] Preferably, reinforcing plates are welded to opposite sides of both of the end three-hole positioning plates, which can improve the structural strength of the end three-hole positioning plates themselves.

[0010] Preferably, the top of the base plate is fixed with an end positioning plate between the two end three-hole positioning plates.
[0011] Compared with the prior art, the beneficial effects of this utility model are: the welding fixture for the tail frame of the seeder adopts a new structural design, the specific contents of which are as follows: (1) the front end of the tail frame of the seeder is placed between two end three-hole positioning plates, and then six cylinders are started at the same time, and the six hole positioning cores are pushed to move at the same time, so that they are inserted into the positioning holes on the tail frame of the seeder, which can fix the front end of the tail frame of the seeder to prevent the tail frame of the seeder from moving or deforming during the welding process; furthermore, the tail end of the tail frame of the seeder is placed between two tail end positioning plates and fixed by multiple screws, thereby completing the fixation of the tail end of the tail frame of the seeder, thereby reducing the workload of the workers and improving work efficiency.
[0012] (2) The staff uses a tool to rotate the screw, so that the threaded rod moves and pushes the hole positioning core to move, so that it is inserted into the positioning hole on the tail frame of the seeder, further improving the firmness of fixing the tail frame of the seeder; furthermore, the front end and the tail end of the seeder tail frame can be positioned by the two end three-hole positioning plates and the two tail end positioning plates, ensuring the accuracy of the relative position between each component.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-5 This utility model provides the following technical solution: welding fixture for the tail frame of a seeder;
[0022] Example 1: To address the problem that existing seeder tail frame welding fixtures mostly require workers to use tools and multiple screws to fix the seeder tail frame, resulting in time-consuming and labor-intensive operations, increased workload, and low work efficiency, the following solution is disclosed. Please refer to the following for details. Figures 1-5As shown, the device includes a square tube frame 1, with a base plate 2 fixedly connected to the top of the square tube frame 1. A tail-end positioning plate 3 is fixed to the right side of the upper surface of the base plate 2, and a three-hole end positioning plate 4 is provided on the left side of the upper surface of the square tube frame 1. A fixing plate 5 is connected above the opposite sides of the two end three-hole positioning plates 4, and a cylinder 8 is installed on the side of the fixing plate 5 away from the end three-hole positioning plate 4. The two fixing plates 5 are fixedly connected to the side of the end three-hole positioning plate 4 by multiple mounting positioning posts 12. Every three cylinders 8 are distributed on the side of one fixing plate 5, and the output end of the cylinder 8 corresponds one-to-one with the position of the hole positioning core 14. Hole positioning cores 14 are provided at equal angles inside the two end three-hole positioning plates 4. Sleeves are fitted onto the outer sides of the opposite ends of the multiple hole positioning cores 14. Two tail-end positioning plates 3 are symmetrically distributed on the top of the base plate 2, and the two tail-end positioning plates 3 are fixedly connected to the tail end of the seeder tail frame by multiple screws. Threaded rods 10 are connected to the inside of the two fixing plates 5.
[0023] Workers place the welding fixture for the seeder tail frame between the two tail-end positioning plates 3 and the two end three-hole positioning plates 4. This positions the end of the seeder tail frame, ensuring the accuracy of the relative positions of each component. Then, workers insert multiple screws into the fixing holes inside the two tail-end positioning plates 3 and tighten them with tools to fix the tail end of the seeder tail frame. Then, six cylinders 8 are started simultaneously, pushing the six cylinders 8 to move the six-hole positioning cores 14 simultaneously, so that they are inserted into the positioning holes on the seeder tail frame. This fixes the front end of the seeder tail frame, preventing the seeder tail frame from moving or deforming during the welding process, thereby reducing the workload of workers and improving work efficiency.
[0024] Example 2: Unlike Example 1, this example utilizes a threaded rod 10 to move the hole positioning core 14, further improving the stability of the seeder tail frame. See details... Figure 4 and Figure 5 As shown, the two ends of the hole positioning core 14 penetrate the interior of the end three-hole positioning plate 4, and the hole positioning core 14 and the end three-hole positioning plate 4 are slidably connected. The two ends of the threaded rod 10 penetrate the interior of the fixing plate 5, and the threaded rod 10 and the fixing plate 5 are threadedly connected. The threaded rod 10 and the hole positioning core 14 are positioned correspondingly. The outer sides of the opposite ends of the two threaded rods 10 are fitted with clamping plates 9. The top of the base plate 2 is fixed between the two end three-hole positioning plates 4 with an end positioning plate 13.
[0025] The workers use tools to rotate the threaded rod 10, causing the threaded rod 10 to move and push the hole positioning core 14 to move, so that it is inserted into the positioning hole on the tail frame of the seeder, further improving the firmness of the tail frame of the seeder. At the same time, the end positioning plate 13 is used to ensure that the tail frame of the seeder is accurately placed on the welding fixture.
[0026] Example 3: Unlike Example 2, this example utilizes a reinforcing plate 11 to enhance the structural strength of the end three-hole positioning plate 4 and improve its service life. See details... Figure 1 , Figure 2 and Figure 4 As shown, reinforcing plates 11 are welded to the opposite sides of the two end three-hole positioning plates 4. The reinforcing plates 11 can improve the structural strength of the end three-hole positioning plates 4. The front and rear ends of the top of the base plate 2 are bolted to the mounting brackets 6, and the top of the mounting brackets 6 is bolted with manual valves 7.
[0027] By setting the manual valve 7, the size of the fluid channel can be controlled, thereby controlling the fluid flow rate into the cylinder 8, achieving precise control of the movement speed and direction of the cylinder 8. Furthermore, the reinforcing plate 11 can enhance the structural strength of the end three-hole positioning plate 4 and improve its service life.
