Description

Technical Field

[0001] The present invention relates to the technical field of installation and fixation of automotive parts, and more particularly, to a pusher for automatically pressing and installing a leaf spring nut. Background Art

[0002] In the field of industrial production, especially in industries such as automobile manufacturing, the installation of leaf spring nuts is a common technological process. As an important connecting and fastening element for the engine under guard, rear windshield, and floor under guard, the traditional installation method of leaf spring nuts mainly relies on manual operation, which has problems such as low efficiency, unstable quality, high labor intensity of employees, and high risk of work-related injuries.

[0003] In view of the above problems, in practical applications, due to design defects of existing pushers, such as difficult opening of the "front mouth" of the leaf spring nut, easy failure of the trigger spring, poor loading of the clip magazine, and unreasonable layout of the pneumatic system, the effectiveness of the pushers is severely restricted. Among them, the current design of the pusher fails to fully consider the structural characteristics of the leaf spring nut, resulting in easy impact on the product when attempting to open the "front mouth" of the leaf spring nut, causing installation failure or product damage; there are also problems with the loading of the clip magazine. The clip magazine cannot effectively load the leaf spring nuts, and the spring mechanism of the clip magazine is prone to failure, resulting in frequent jams or inability to operate continuously during the use of the pusher.

[0004] In view of the above technical defects, there is an urgent need to design a new type of pusher to solve the technical bottleneck of the existing pusher in the installation of leaf spring nuts and achieve an efficient, stable, and safe automated installation process. Summary of the Invention

[0005] The purpose of the present invention is to provide a pusher for automatically pressing and installing a leaf spring nut to solve the above technical problems.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0021] In summary, compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. By optimizing the structural design of the pusher clip, the present invention adds a mouth-opening mechanism. Through the precise cooperation of the pressing block assembly and the swinging assembly, it can automatically open when the reed clip is pushed out, ensuring that the reed clip can be accurately and stably installed in the designated position, avoiding hitting the product and improving the installation success rate. At the same time, the design of the mouth-opening part can match the opening for inserting the reed clip to ensure the correct opening of the reed clip. Meanwhile, the accommodating cavity, clip-out channel, clip-out port, and out-warehouse port inside the pusher main body are reasonably designed to ensure the stability and accuracy of the reed clip during the pushing-out process.

[0023] 2. The pusher main body of the present invention adopts the docking design of the left cavity and the right cavity, and the pressing block assembly adopts the design of docking and assembling the left pressing block and the right pressing block that match the pusher main body on the pusher main body, making the overall structure of the pusher clip compact, reducing unnecessary space occupation, and enhancing the overall stability at the same time; a magnetic attraction block is added to the top platform of the pusher main body to position and lock the clip bin on the pusher main body, and a protection component is added outside to play a role in closing and protecting important components of the overall structure.

[0024] 3. The trigger mechanism of the present invention adopts an embedded torsion spring structure, and a trigger spring is made of a material with high strength and high durability. The overall structural optimization design reduces the failure probability of the trigger and improves the overall reliability of the pusher clip. The arc design of the trigger body helps to increase the mechanical stability and durability of the trigger; the design of the whistle-shaped groove provides a stable installation position for the torsion spring, and the installation layout of the torsion spring ensures that the torsion spring can stably provide elastic force during operation. The torsion spring provides a reset force for the trigger, enabling the trigger to quickly return to the initial position after release and be ready for the next operation.

[0025] 4. The clip bin of the present invention is designed with a back-opening type. The reed clip group puts forward specification requirements before design and is arranged in multiple pieces in a group. When filling the reed clips, only multiple pieces in a group need to be put into the clip bin, without adding one by one, improving the overall working efficiency.

[0026] 5. The present invention optimizes the pneumatic layout, sets a stationary handle part under the pusher main body, raises the pusher clip cavity to increase the surrounding space, and the space for the pneumatic switch is larger. The spatial layout of the pneumatic switch and the pusher clip cavity is reasonably adjusted to avoid pressing the air pipe, ensuring the stable operation of the pneumatic system and improving the safety of the operator at the same time.

Detailed implementation manners

[0040] The following will describe in detail the specific embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments given here are only for explaining and interpreting the present invention and cannot be used to limit the present invention.

[0041] It should be noted that many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention may have other embodiments and its variations, and thus the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0042] As Figures 1 to 12 shown, the present invention provides a pusher for automatically pressing and installing a reed nut, which is used for installing a clamping bin 1 and pushing a reed clip 100, and includes a pushing clip main body 2, a pushing mechanism 3, a mouth-opening mechanism 4, and a trigger mechanism 5 for controlling the pushing out of the reed clip 100;

[0043] The stapling body 2 is formed by docking a left cavity 21 and a right cavity 22. An accommodation cavity 20 for installing the pushing mechanism 3 is formed inside the docking of the left cavity 21 and the right cavity 22. The front end of the accommodation cavity 20 is an outlet for staples 200. Below the stapling body 2 away from the outlet for staples 200, there is a stationary handle 23 and a trigger mechanism 5 pivotally connected to the stapling body 2;

[0044] The pushing mechanism 3 includes a push rod 31 and a cylinder assembly 30. The front end of the push rod 31 has a pushing portion 310 opposite to the outlet for staples 200. A section from the pushing portion 310 to the outlet for staples 200 is an outlet channel for staples (not shown in the figure). Arc-shaped wing ends 320 are symmetrically arranged and extend outward on both sides of the push rod 31, and the rear end thereof is connected to the driving end of the cylinder assembly 30;

[0045] The opening mechanism 4 includes a pressing block assembly 41 and a swinging assembly 42. On the stapling body 2 at the outlet channel, there is a top platform 24 for installing the pressing block assembly 41. Extension portions 240 are symmetrically arranged on both sides of the top platform 24. The outer edges of the extension portions 240 and the top platform 24 are provided with a guard plate 241 for transition. The bottom outer edge of the pressing block assembly 41 is matched and connected with the vertical guard plate 241 to form a swinging space 25 for accommodating a pair of the swinging assemblies 42. The swinging assemblies 42 are in a bow shape. The bow openings of a pair of the swinging assemblies 42 face each other and are symmetrically arranged on the corresponding extension portions 240. The pressing block assembly 41 has a clamping cavity 40 for vertically installing the clip magazine 1, and the two lateral ends of the clamping cavity 40 communicate with the outlet channel;

[0046] When the cylinder assembly 30 drives the push rod 31 to perform a linear motion, the pushing portion 310 pushes out the spring clip 100 in the clip magazine 1. The arc-shaped wing ends 320 touch and push one end of the swinging assembly 42 towards the vertical guard plate 241 of the extension portion 240, and the other ends of the pair of the swinging assemblies 42 both extend into the outlet channel and open the spring clip 100.

[0047] In this embodiment, the cooperative effect of the swinging assembly: The swinging assemblies 42 in the opening mechanism 4 work together under the push of the push rod 31, realizing the smooth pushing out and opening of the spring clip 100, and reducing the error during the installation process; The touching mechanism of the arc-shaped wing end: The arc-shaped wing ends 320 touch and push the swinging assembly 42, realizing the effective control of the swinging assembly and ensuring the correct posture of the spring clip 100; The reasonable layout of the swinging space: The swinging space 25 formed by the pressing block assembly 41 and the vertical guard plate 241 provides enough movement range for the swinging assembly 42, ensuring the smooth opening of the spring clip 100.

[0048] During specific implementation, such as Figures 7 to 9As shown, the swing assembly 42 includes an opening rod 421, a fixing pin 422 and an L-shaped movable rod 423, a pin hole 4230 for installing the fixing pin 422 is opened in the middle of the horizontal section 4231 of the L-shaped movable rod 423, the vertical guard plate 241 is divided into a right-angle section 2411 and an extension section 2412, the threaded end of the fixing pin 422 is arranged in the transition zone between the right-angle section 2411 and the extension section 2412, the axial end of the fixing pin 422 is passed through the pin hole 4230, and the first torsion spring 43 and the pressure block are sleeved. The opening rod 421 is connected with the component 41, and the other end of the opening rod 421 is sleeved with the first torsion spring 43 and fixedly connected with the pressure component; one end of the opening rod 421 is provided with a rotating pin 4211 in the vertical direction which is slidably matched with the free end of the horizontal section 4231 of the L-shaped movable rod 423, and the other end is provided with a mouth portion 4212 in the extending direction, the opening rod 421 is tightly attached to the right-angle section 2411 of the vertical guard plate 241 and the mouth portion 4212 is always facing the clamping channel, and the vertical section 4232 of the L-shaped movable rod 423 faces the clamping channel to form a bow structure.

[0049] In the swing assembly, the design of the horizontal section 4231 and the vertical section 4232 of the L-shaped movable rod 423 enables the swing assembly 42 to swing flexibly in the bow structure. The fixing pin 422 passes through the pin hole 4230 and is fixed in the transition zone between the right-angle section 2411 and the extension section 2412 of the vertical guard plate 241, providing a stable fixing point for the swing assembly. The other end of the fixing pin 422 is sleeved with the first torsion spring 43, providing elastic force, so that the opening rod 421 can automatically reset after the spring clip 100 is pushed out. The rotating pin 4211 of the opening rod 421 is slidably matched with the free end of the horizontal section 4231 of the L-shaped movable rod, ensuring the precise guidance of the swing assembly during the swinging process. The opening mouth 4212 of the opening rod 421 is always facing the clamp outlet channel, ensuring that the spring clip 100 can be accurately pushed out and sent to the correct position. The swing assembly 42 of the bow structure can achieve effective swinging in a limited space while maintaining a compact structure. The design of the opening rod 421 close to the right angle section 2411 reduces friction during the swinging process and improves the smoothness of the movement; when the opening mouth 4212 of the opening rod 421 extends into the spring clip 100, it can interact with the spring clip more effectively to improve the pushing efficiency. The design of the right angle section 2411 and the extension section 2412 of the vertical guard plate 241 optimizes the space utilization of the swing component inside the clamp pusher, making the component layout more reasonable.

[0050] The above arrangement enables the openings of the two swinging assemblies to be relatively arranged close to the vertical section to extend and retract, always facing the clamping channel. During the clamping process, the openings can be aligned with the clamping opening of the reed clamp to achieve lateral extension and retraction.

[0051] Preferably, if Figure 9As shown, the open mouth part 4212 has an inclined surface 42120 facing the clip - out channel. The cross - section of the open mouth part 4212 is an isosceles triangle, which has a long base 42123, a bottom hypotenuse 42121, and a side hypotenuse 42122. The acute angle between the long base 42123 and the bottom hypotenuse 42121 forms a blade end (not shown in the figure) along the length direction of the open mouth part 4212, and the long base 42123 forms the inclined surface along the length direction of the open mouth part 4212.

[0052] In this embodiment, the cross - section of the open mouth part 4212 is an isosceles triangle. The long base forms the inclined surface of the open mouth part along the length direction of the open mouth part 4212. The acute - angle range between the long base 42123 and the bottom hypotenuse 42121 is 30 - 60°. The side hypotenuse of the isosceles triangle is parallel to the axis of the rotating pin. The blade end smoothly abuts against the clip - opening of the reed clip under the guiding action of the inclined surface. During the continuous clip - pushing process, the opening of the reed clip is completed.

[0053] The blade end matches the opening of the reed clip 100 when the reed clip 100 is pushed out. The open mouth part can smoothly push the clip - opening of the reed clip while maintaining the correct direction and posture. The inclined surface 42120 has a guiding function to help the reed clip 100 move along a predetermined path, improving the accuracy and reliability of the clip - opening - pushing process. In addition, due to the existence of the inclined surface 42120, the possibility of jamming of the reed clip 100 during the pushing - out process can be reduced. The cross - section of the isosceles triangle and the design of the inclined surface help to optimize the distribution of the pushing - out force, making it easier for the reed clip 100 to open its mouth and thus easier to be pushed into the product.

[0054] During specific implementation, as Figure 6 shown, the outer edge of the arc - shaped wing end 320 successively has a first hypotenuse 321, a straight edge 322, and a second hypotenuse 323 along the clip - out direction. The first hypotenuse 321 forms a 30° angle with the central axis of the clip - pushing body 2, and the second hypotenuse 323 forms a 60° angle with the central axis of the clip - pushing body 2.

[0055] During specific implementation, as Figure 4 shown, the pressing - block assembly 41 is composed of a symmetric left pressing block 411 and a right pressing block 412. The left pressing block 411 and the right pressing block 412 are respectively installed on the top platform 24 formed by the left cavity 21 and the right cavity 22. The clamping cavity 40 formed by the butt - joint of the left pressing block 411 and the right pressing block 412 has a T - shaped cross - section and matches the cross - section of the clip - bin 1. There is a clip - bin installation interface 242 on the top platform 24 directly below the T - shaped head of the clamping cavity 40, and there are counter - bores 243 for installing magnetic - attraction blocks 26 on both sides of the clip - bin installation interface 242.

[0056] Preferably, as Figure 11 and12 As shown, the clip bin 1 is of a back-opening type. A group of spring clip sets arranged in order is provided inside the clip bin 1. The spring clip sets are formed by multiple spring clips 100 to form a group. A bin outlet 10 corresponding to the clip outlet 200 is laterally opened at the bottom end of the clip bin. A connection mechanism 14 that is matingly connected with the card interface 242 is provided at the bottom of the clip bin. The connection mechanism 14 has right-angle pressing pieces 140 that cover the bottom end and the side surface of the clip bin on both sides. The right-angle pressing piece 140 is magnetically attracted by the magnetic attraction block 26 to magnetically fix the clip bin 1 on the top platform 24.

[0057] In this embodiment, the capacity of the clip bin 1 is designed according to production requirements. During normal production, the number specification of a group of spring clips 100 is 30 pieces / group or 50 pieces / group. A group of spring clips 100 is directly added into the back-opening type clip bin 1, which is convenient and fast. In the past, when the front clip bin had an upper opening, the spring clips 100 had to be put in one by one, and it took 3 to 5 minutes to place a group. The design of the back-opening type clip bin 1 allows a group to be directly added, and it only takes 2 - 3 seconds to make the clip bin 1 full, improving production efficiency.

[0058] Specifically, as Figure 12 shown, from the unfolded state of the clip bin 1 of this embodiment, it can be known that the clip bin 1 includes a clip bin upper cover 11 and a clip bin lower cover 12. One end of the clip bin upper cover 11 and the clip bin lower cover 12 is connected by an opening and closing mechanism 13. An opening at one end of the clip bin upper cover 11 away from the opening and closing mechanism 13 forms the bin outlet 10. The connection mechanism 14 is provided at one end of the clip bin lower cover 12 away from the opening and closing mechanism 13. The clip bin lower cover 12 is snap-connected to the snap cavity 40 of the clip pushing main body 2 through the connection mechanism 14. A chute (not shown in the figure) is provided inside the clip bin lower cover 12. Spring clips 100 are installed in the chute. A top clip mechanism 15 is provided at one end of the chute close to the opening and closing mechanism 13. The top clip mechanism 15 can slide back and forth along the chute. When the top clip mechanism 15 slides forward towards the bin outlet, the spring clip 100 can be sent to the bin outlet for positioning; when the top clip mechanism 15 slides backward, the spring clip 100 can be stably clamped and installed in the chute. The above realizes the back-opening type clip bin through the opening and closing mechanism 13, which is convenient for installing the spring clips 100 in the clip bin. By placing the spring clip group according to the length of the chute inside the clip bin lower cover 12, rapid feeding can be achieved, and at the same time, it can be seen whether the front and back placement directions of the spring clips 100 meet the standard requirements.

[0059] During specific implementation, as Figure 1 、 Figure 2 and Figure 4As shown, the top platform 24 located at the clamp outlet 200 is provided with a hanging platform 244 outwardly, and a triangular eave 414 and a stepped platform 413 are respectively extended outwardly above and below the pressing block assembly 41 at the clamp outlet direction end, and the lower side of the stepped platform 413 is matched and overlapped with the hanging platform 244, and the top surface thereof and the lower inclined surface opposite to the triangular eave 414 form a mounting docking port 7, and the included angle of the mounting docking port 7 is 40 to 45°.

[0060] This embodiment provides for the accuracy of push clamping by setting an installation docking interface, while ensuring the stability and alignment of the components during installation, thereby improving the work efficiency of clamping.

[0061] When implementing it, Figure 10 As shown, the trigger mechanism 5 includes a trigger body 51 and a second torsion spring 52. The trigger body 51 is arc-shaped, and a whistle-shaped groove 510 is opened downward on the top. The trigger body 51 on both sides of the top of the whistle-shaped groove 510 is provided with through holes 511. The second torsion spring 52 is mounted on the top of the whistle-shaped groove 510. The trigger body 51 is installed on the push clamp body 2 by passing through the through hole 511 and the torsion spring hole through the latch 53. One end of the second torsion spring 52 has a rotating arm abutting against the bottom end of the whistle-shaped groove 510, and the other end of the rotating arm abuts against the push clamp body 2.

[0062] When implementing it, Figure 4 As shown, the cylinder assembly 30 includes a cylinder 300, a pneumatic switch 301 and a pneumatic joint 303. The pneumatic switch 301 is arranged in the stationary handle 23 below the cylinder 300. The pneumatic switch 301 is connected to the pneumatic joint 303 through an air pipe 302. The trigger mechanism 5 is located at the front end of the stationary handle 23. In this embodiment, the cylinder 300 adopts a single-acting extrusion type cylinder, which performs reciprocating linear motion in one direction. Based on the pneumatic principle, when compressed air enters one side of the cylinder 300, it pushes the piston rod to move outward to achieve the working stroke; when the pneumatic pressure is released, the piston rod returns to the initial position by spring force or external load. Pulling the trigger mechanism 5 triggers the pneumatic switch 301 to open, and the cylinder 300 is ventilated to perform the pushing and clamping work.

[0063] During specific implementation, it also includes a protection component 6, which includes a left cover 61, a right cover 62 and a rear cover 63. The rear cover 63 is provided at the rear end of the left cavity 21 and the right cavity 22 that are away from the clamp outlet 200. The push-clamp body 2 located at the connection between the driving end of the cylinder assembly 30 and the push rod 31 is laterally provided with a large through cavity 27. The left cover 61 and the right cover 62 are respectively matched and installed on the large through cavity 27 of the left cavity 21 and the right cavity 22.

[0064] In this embodiment, the push clip spring clip 100 of the push clip device is installed on the engine under shield, rear baffle or floor bottom shield (collectively referred to as the product below). The materials of these automotive component products are lower in hardness than steel and are prone to deformation. For the installation of products with these materials, the specific working principle of the push clip device is as follows: Before work, first install the clip magazine 1 into the clamping cavity 40 formed by the push clip main body 2 and the pressing block assembly 41. The connecting mechanism 14 of the clip magazine 1 is clamped in place with the clamping port 242. At the same time, the magnetic attraction block 26 plays a role in positioning and locking the clip magazine 1, and the clip magazine 1 is not easily pulled out. Align the clip outlet 200 of the push clip main body 2 with the product position, pull the trigger mechanism 5, touch the pneumatic switch 301, and the air path is connected. The push rod 31 advances towards the clip outlet 200 under the action of the single-acting extrusion type cylinder. Before the spring clip 100 is ejected, first the arc-shaped wing end 320 touches and pushes the vertical section 4232 of the L-shaped movable rod 423 towards the vertical guard plate 241 of the extension part 240. At the same time, the opening rods 421 of a pair of swing assemblies 42 all face the clip outlet channel and horizontally extend into the spring clip 100 to open the front mouth of the spring clip 100. Immediately after the front mouth of the spring clip 100 is opened, the top push part 310 instantly pushes the spring clip 100 from the outlet of the magazine to the position where it catches the product. When the product is completely caught, the cylinder 300 returns, the push rod 31 retracts, the movable rod is released, and the opening rod 421 instantly retracts, completing the installation of one spring clip 100.
