Description

Technical Field

[0001] This utility model belongs to the field of mechanical automation conveying, specifically relating to a double-door nut conveying gun, which is suitable for high-speed and precise conveying of nuts in industries such as automobiles and sheet metal. Background Technology

[0002] A nut feeder gun is an automated device used to quickly and accurately feed nuts to a predetermined station for tightening or welding. Traditional nut feeder guns typically use an upward-opening or downward-opening gate on the receiving seat. In practical applications, especially under high-speed conveying conditions, this type of structure has the following drawbacks: 1. Poor centering effect: When the conveying rod (or conveyor bar) is in operation, the nut is prone to deflection in the receiving seat, which causes the threaded holes of the rod and nut to be misaligned, resulting in conveying failure or damage to the threads.

[0003] 2. Uneven force distribution: When a unilaterally opening and closing gate opens and closes, the clamping force on the nut is uneven, affecting the nut's posture stability.

[0004] 3. Severe wear: To ensure clamping force, springs with a large stiffness coefficient are usually required. This not only increases the resistance to the movement of the push rod, but also aggravates the wear of the push rod and the internal parts of the receiving seat, affecting the service life of the equipment.

[0005] Therefore, there is an urgent need for a nut delivery gun structure that can adapt to high-speed conveying, accurate centering, and low wear. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a double-door nut conveying gun, which is accurate in centering, has low wear, long service life, and is particularly suitable for high-speed conveying.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A double-door nut delivery gun includes a delivery cylinder, a delivery pipe support, a gun support, a delivery rod, a material pipe, and a receiving seat. The receiving seat has openable and closable gates on its left and right sides, and the two gates are symmetrically hinged to the left and right sides of the receiving seat via a pivot. The delivery rod passes through the receiving seat, and its front end is provided with a magnetic sleeve for attracting and pushing nuts.

[0008] Preferably, the conveying rod is fitted with a first return spring and a second return spring. The first return spring is supported between the receiving seat and the conveying pipe support, and the second return spring is supported between the conveying pipe support and the conveying cylinder, which together are used to realize the automatic reset of the conveying rod.

[0009] Preferably, the material tube is fixed to the conveying pipe support by a material tube clamp and a material tube clamp cap, and is locked by a first hexagon socket bolt and a second hexagon socket bolt.

[0010] Preferably, the cylinder rod of the conveying cylinder is provided with a cylinder rod sleeve.

[0011] Preferably, the receiving seat has a guide hole that fits with the conveying rod with a clearance, and the conveying rod passes through the guide hole to guide it to maintain a centered position during movement.

[0012] Preferably, both the first and second reset springs are light-load springs, and their spring stiffness is configured such that the conveying rod can automatically reset under no external force, and the inertial force generated when the conveying rod reciprocates at high speed is insufficient to cause it to flutter.

[0013] Preferably, the magnet sheath is detachably mounted on the front end of the conveyor rod.

[0014] Preferably, the rotating shaft mounting hole on the receiving seat is an oblong hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The double-door structure on the left and right sides ensures that the nut is subjected to uniform force during transportation and is more accurately positioned, making it especially suitable for high-speed transportation; 2. The conveyor rod is always aligned under the action of the return spring, reducing uneven wear and extending service life; 3.

[0017] 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.

[0018] Please see Figure 1 The present invention provides the following technical solution: A double-door nut delivery gun includes a delivery cylinder 1, a delivery pipe support 2, a gun support 4, a delivery rod 6, a feed pipe 13, and a receiving seat 14. The receiving seat 14 has openable and closable gates 16 on its left and right sides respectively. Nuts slide into the receiving seat 14 via the feed pipe 13 under gravity. The two gates (left and right gates) are symmetrically hinged to the left and right sides of the receiving seat 14 via pivots 15, forming a double-door structure that opens left and right. The advantage of this left-right opening is that it allows for an additional centering rod (delivery rod) compared to traditional methods. The left and right opening ensures even force distribution during nut extension, resulting in higher accuracy and efficiency in nut delivery. When closed, the inner sides of the two gates together form a cavity for accommodating and positioning the nut, receiving the nut from the feed pipe 13. The delivery rod 6... A magnetic sleeve 7 is provided at the front end of the material receiving seat 14. The conveying cylinder 1 pushes the conveying rod 6 forward, and the magnetic sleeve 7 attracts the nut and pushes it into the material receiving seat 14. The stop gate 16 opens when the nut enters and closes under the action of the return spring after the conveying is completed. Throughout the process, the nut remains concentric with the conveying rod, achieving high-speed and precise conveying and keeping the conveying accuracy at its optimal level.

[0019] To further ensure accuracy, when the reverse flange nut is conveyed, the inner side of the stop gate 16 is provided with a guide boss that protrudes into the receiving seat 14. This guide boss constitutes a straightening platform, which is used to clamp and straighten the position of the nut from both sides when the stop gate 16 is closed, to make fine adjustments and straighten it, and to ensure that the center line of its threaded hole is concentric with the axis of the conveying rod 6.

[0020] A first return spring 11 and a second return spring 12 are fitted onto the conveyor rod 6. The first return spring 11 is supported between the receiving seat 14 and the conveyor pipe support 2, and the second return spring 12 is supported between the conveyor pipe support 2 and the conveyor cylinder 1. Together, they are used to achieve automatic reset of the conveyor rod 6, ensuring that the two stop gates remain closed without external force. The stop gate 16 is kept normally closed by spring force. When the conveyor rod 6 is advanced, the stop gate is pushed open by the conveyor rod or nut, achieving automatic opening and closing. The opening angle of the stop gate 16 is limited so that it forms a guide channel with the conveyor rod 6 when open, ensuring that the nut is subjected to uniform force. Smaller springs can be used to reduce wear on the conveyor rod and extend its service life, while also being adaptable to the user's requirements for the nut delivery state.

[0021] The feed tube 13 is fixed to the conveying tube support 2 by the feed tube clamp 8 and the feed tube clamp cover 10, and is locked by the first internal hex bolt 3 and the second internal hex bolt 9.

[0022] The cylinder rod of the conveying cylinder 1 is provided with a cylinder rod sleeve 5.

[0023] The receiving seat 14 has a guide hole inside that is clearance-fitted with the conveying rod 6. The conveying rod 6 passes through the guide hole to guide it to maintain a centered position during movement.

[0024] The first reset spring 11 and the second reset spring 12 are both light-load springs. Their spring stiffness is configured such that the conveying rod 6 can automatically reset under no external force, and the inertial force generated when the conveying rod 6 reciprocates at high speed is insufficient to cause it to flutter.

[0025] The magnet sleeve 7 is detachably mounted on the front end of the conveyor rod 6 for easy maintenance or replacement.

[0026] The mounting hole for the rotating shaft 15 on the receiving seat 14 is an oblong hole. The receiving seat 14 has a guide structure inside to guide the conveying rod 6 to maintain its centered position during movement and to ensure that the nut and the conveying rod 6 are concentric.

[0027] During operation, the conveying cylinder 1 actuates, pushing the conveying rod 6 forward. The tip of the push rod at the front end of the conveying rod 6 presses against the nut, overcoming the forces of the first return spring 11 and the second return spring 12, and pushes open the left and right stop gates. Because the push is symmetrical from left to right, the nut receives a uniform force during its forward movement, maintaining a stable posture and allowing the conveying rod 6 to accurately insert into the threaded hole of the nut, completing the conveying process.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
