Description

Technical Field

[0001] The utility model relates to a nut conveying device, and more specifically, mainly relates to an upward nut conveying gun which is easy to adjust. Background Art

[0002] The nut conveying gun is a conveying mechanism used in an automatic welding system. Its purpose is to convey the nuts upward to the welding station in sequence so that the subsequent welding processes can be completed one by one. Therefore, this type of conveying mechanism has high requirements for the stability of nut conveying and the specific conveying direction. If the direction of the nut conveying deviates or even falls during the conveying process, it will affect the welding operation. However, the use of cylinders as power has a large impact force during conveying, which can easily cause the nuts to fall due to inertia. In addition, different welding machines have different specifications and sizes, which also puts higher requirements on the conveying angle of the conveying gun. The conveying angle of the traditional conveying gun is difficult to adjust due to its structural limitations and is not suitable for working with more welding machines. Therefore, it is necessary to further study and improve the structure of the nut conveying gun. Utility Model Content

DETAILED DESCRIPTION

[0015] The utility model will be further described below in conjunction with the accompanying drawings.

[0016] refer to Figure 1As shown, one embodiment of the utility model is an upward nut conveying gun which is easy to adjust, comprising a mounting seat 1, which is a supporting component of the conveying gun, and a conveying cylinder 2 is installed at the rear of the mounting seat 1, and the conveying cylinder 2 is a driving component of the conveying gun. The output end of the conveying cylinder 2 is dynamically connected to a swinging material pocket 5, and the swinging material pocket 5 is a conveying component of the conveying gun. More importantly, the aforementioned swinging material pocket 5 needs to be movably mounted on a material pocket displacement mechanism 3, and its function is to make the swinging material pocket 5 correspond to the discharge port of the conveying pipe 6 in the initial position; then the material pocket displacement mechanism 3 is mounted on the front end of a guide rail 4, and the guide rail 4 is movably mounted on the mounting seat 1, and the conveying cylinder 2 is used to drive the swinging material pocket 5 to move forward along the extension direction of the guide rail 4.

[0017] The above-mentioned conveying pipe 6 is installed on the mounting base 1 through the conveying base 10, and a material blocking rack 7 is also installed on the conveying base 10, and a material blocking cylinder 8 is installed on the material blocking rack 7, and the output direction of the material blocking cylinder 8 corresponds to the discharge port of the conveying pipe 6; a material blocking block (not shown in the figure) is also provided at the lower part of the aforementioned material blocking rack 7, and the function of the material blocking block is to block the first nut in the current conveying pipe 6 so that it is placed on the swinging material pocket 5.

[0018] Preferably, in order to facilitate fine-tuning the conveying angle of the conveying gun, a clamping movable plate 101 can be provided on the mounting seat 1, and the clamping movable plate 101 is clamped and fixed on the crossbeam at the lower end of the fixed column 102, thereby realizing the installation of the mounting seat 1, and the crossbeam rotates in the clamping movable plate 101 to realize the overall fine-tuning of the conveying gun angle. At the same time, in order to avoid excessive vibration when the conveying cylinder 2 drives the swinging material pocket 5 to reset, corresponding buffer blocks 11 can be provided at the ends of the conveying cylinder 2 and the ends of the guide rails 4, and then when the swinging material pocket 5 is reset, the two buffer blocks 11 first contact, thereby playing a role of shock absorption. At the same time, by providing two corresponding buffer blocks 11, a certain limit effect can also be played on the swinging material pocket 5, avoiding deviation between the position of the material outlet of the conveying pipe 6 after its reset.

[0019] In this embodiment, a blocking block is added to the lower part of the blocking rack 7 to block the first nut in the conveying pipe, thereby eliminating a blocking cylinder 2, further simplifying the structure of the upward nut conveying gun and the cylinder control; and the buffer device can also reduce the vibration generated when the conveying cylinder drives the nut tray to reset, thereby preventing position deviation after resetting.

[0020] As Figure 2 As shown, when the upward nut conveying gun of this embodiment is in use, the swinging material pocket 5 is in the same straight line with the discharge port of the conveying pipe 6 at the initial position, and the straight line is parallel to the guide rail 4 in the vertical plane. This ensures that the nuts conveyed in the conveying pipe 6 can fall into the swinging material pocket 5, and the swinging material pocket 5 can also be provided with a groove that matches the nut to prevent the nut from falling during the conveying process.

[0021] Furthermore, to ensure that the delivery gun can cooperate with subsequent welding equipment, a swinging connecting rod 51 is provided at the end of the swinging material pocket 5, and the portion between the swinging connecting rod 51 and the swinging material pocket 5 is movably fixed to the material pocket displacement mechanism 3 through a rotating shaft 9, and the swinging connecting rod 51 is movably connected to the output end of the delivery cylinder 2, and the rotating shaft 9 has a limit buckle, which is used to make the swinging material pocket 5 swing upward to be flush with the horizontal plane under the drive of the delivery cylinder 2. It is preferred here that, in order to enable the swinging material pocket 5 to be reset to the initial state in time after the delivery cylinder 2 is retracted, a reset spring can be added between the material pocket displacement mechanism 3 and the output end of the delivery cylinder, and the elastic force of the reset spring is used to reset the material pocket displacement mechanism 3.

[0022] refer to Figure 1 and Figure 2 As shown, in the actual use of the above preferred embodiment of the utility model, the conveying cylinder 2 and the blocking cylinder 8 are both connected to the external air source, and the initial state of the conveying gun is as follows Figure 2 As shown, at this time, the nuts in the conveying pipe 6 are discharged from the discharge port under the action of the air flow, and the current first nut is blocked by the blocking block at the bottom of the blocking frame 7, and then the blocking cylinder 8 extends the nut behind the original first nut, so that only the first nut can fall below the discharge port, making it fall on the swinging material pocket 5, and then the conveying cylinder 2 extends forward, so that the swinging material pocket 5 moves forward along the extension direction of the guide rail 4. When the guide rail 4 is extended to the right position, the conveying cylinder 2 continues to push the swing connecting rod 51 forward, so that the swinging material pocket 5 flips upward to be flush with the horizontal plane, as shown in the specific example. Figure 1 As shown, it is convenient for subsequent welding equipment to weld the nuts. After the delivery is completed, the output end of the delivery cylinder 2 retracts, drives the swing material pocket 5 to swing downward through the swing connecting rod 51, and then retracts to Figure 2 The initial position shown, at this time, the swing material pocket 5 is placed at the discharge port of the conveying pipe 6, thereby completing one conveying. During operation, in cooperation with the welding machine, the above process is repeated continuously.

[0023] Moreover, the main difference and advantage of the upward conveying method over the traditional method is that the nuts or screws can be conveyed to the upper electrode first and then the workpiece can be placed, thereby reducing the cycle time and improving production efficiency compared to the traditional method of placing the workpiece first and then the nuts or screws. At the same time, some specific workpieces cannot be conveyed by the traditional downward conveying method, and upward conveying can solve this problem.
