DETAILED DESCRIPTION
[0040] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments given here are only used to illustrate and explain 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 to facilitate a full understanding of the present invention. However, the present invention may also have other implementations and variations thereof. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.
[0042] like Figures 1 to 12 As shown, the present invention provides a clamp pusher for automatically pressing and installing a spring nut, which is used to install a clamp bin 1 and push a spring clamp 100, and includes a clamp pusher body 2, a propulsion mechanism 3, a mouth opening mechanism 4, and a trigger mechanism 5 for controlling the pushing out of the spring clamp 100;
[0043] The push-clip body 2 is formed by connecting a left cavity 21 and a right cavity 22. The left cavity 21 and the right cavity 22 are connected to form a receiving cavity 20 for installing the propulsion mechanism 3. The front end of the receiving cavity 20 is a clamp outlet 200. The lower part of the push-clip body 2 away from the clamp outlet 200 is provided with a stationary handle 23 and the trigger mechanism 5 pivotally connected to the push-clip 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 push portion 310 opposite to the clamp outlet 200. The section from the push portion 310 to the clamp outlet 200 is a clamp outlet channel (not shown). Both sides of the push rod 31 extend outwardly and are symmetrically provided with arc-shaped wing ends 320, and the rear end thereof is connected to the driving end of the cylinder assembly 30.
[0045] The mouth opening mechanism 4 includes a pressing block assembly 41 and a swinging assembly 42. A top platform 24 for installing the pressing block assembly 41 is provided on the clamp pushing body 2 located at the clamp outlet channel. Extensions 240 are symmetrically provided on both sides of the top platform 24. Guard plates 241 are set up at the outer edges of the extensions 240 and the top platform 24 for transition. The bottom outer edge of the pressing block assembly 41 is matched with the vertical guard plate 241 to form a swinging space 25 for accommodating a pair of swinging assemblies 42. The swinging assembly 42 is arched, and the arches of a pair of swinging assemblies 42 are oppositely and symmetrically arranged on the corresponding extensions 240. The pressing block assembly 41 has a clamping cavity 40 for vertically installing the clamping bin 1. The two lateral ends of the clamping cavity 40 are communicated with the clamp outlet channel.
[0046] When the cylinder assembly 30 drives the push rod 31 to move linearly, the pushing portion 310 pushes the spring clip 100 in the clamping bin 1 out, and the arc-shaped wing end 320 touches and pushes one end of the swing assembly 42 toward the vertical guard plate 241 of the extension portion 240, and the other ends of a pair of swing assemblies 42 extend into and open the spring clip 100 toward the clamping channel.
[0047] In this embodiment, the synergistic effect of the swinging components: the swinging component 42 in the mouth opening mechanism 4 works together under the push of the push rod 31, so as to realize the smooth pushing out and opening of the reed clip 100 and reduce the error in the installation process; the touching mechanism of the arc wing end: the arc wing end 320 touches and pushes the swinging component 42, so as to realize the effective control of the swinging component and ensure the correct posture of the reed clip 100; the reasonable layout of the swinging space: the swinging space 25 formed by the pressure block assembly 41 and the vertical guard plate 241 provides sufficient range of motion for the swinging component 42, so as to ensure the smooth opening of the reed clip 100.
[0048] When implementing it, 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 Fig. 9As shown, the open mouth portion 4212 has an inclined surface 42120 facing the clamp outlet channel, and the cross-section of the open mouth portion 4212 is an isosceles triangle. The isosceles triangle has a long base 42123, a bottom hypotenuse 42121 and a side hypotenuse 42122. The long base 42123 and the bottom hypotenuse 42121 form an acute angle, and the acute angle forms a blade end (not shown) along the length direction of the open mouth portion 4212, and the long base 42123 forms the inclined surface along the length direction of the open mouth portion 4212.
[0052] The cross-section of the open mouth 4212 of this embodiment is an isosceles triangle, and the long base forms an inclined surface of the open mouth along the length direction of the open mouth 4212, and the long base 42123 and the bottom hypotenuse 42121 form an acute angle in the range of 30 to 60°. The side hypotenuse of the isosceles triangle is parallel to the axis of the rotating pin, and the guiding action of the blade end on the inclined surface smoothly presses against the clamping jaws of the reed clamp, and the opening of the clamping jaws of the reed clamp is completed during the continued pushing and clamping process.
[0053] The blade end matches the opening of the reed clip 100 when the reed clip 100 is pushed out, and the opening portion can smoothly push the reed clip into the jaws while maintaining the correct direction and posture. The inclined surface 42120 has a guiding function, helping the reed clip 100 to move along a predetermined path, thereby improving the accuracy and reliability of the jaw pushing process. In addition, due to the presence of the inclined surface 42120, the possibility of the reed clip 100 getting stuck during the pushing process can be reduced. The isosceles triangle cross-section and the inclined surface design help to optimize the distribution of the pushing force, making it easier for the reed clip 100 to open its mouth and thus easier to be pushed into the product.
[0054] When implementing it, Figure 6 As shown, the outer edge of the arc-shaped wing end 320 has a first bevel 321, a straight edge 322 and a second bevel 323 in sequence along the clamping direction. The first bevel 321 forms an angle of 30° with the central axis of the push-clamp body 2, and the second bevel 323 forms an angle of 60° with the central axis of the push-clamp body 2.
[0055] When implementing it, Figure 4 As shown, the pressing block assembly 41 is composed of a symmetrical left pressing block 411 and a right pressing block 412, and 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, and the cross-section of the card-connecting cavity 40 formed by the docking of the left pressing block 411 and the right pressing block 412 is T-shaped and matches the cross-section of the clamping bin 1, and a card interface 242 for installing the clamping bin 1 is provided on the top platform 24 just below the T-shaped head of the card-connecting cavity 40, and countersunk holes 243 for installing the magnetic suction block 26 are provided on both sides of the card interface 242.
[0056] Preferably, if Fig.11 and12 As shown, the clamping bin 1 is of the back-opening type, and an arranged reed clip group is arranged in the clamping bin 1, and the reed clip group is formed by a plurality of reed clips 100. An outlet 10 corresponding to the outlet 200 is opened laterally at the bottom end of the clamping bin, and a connecting mechanism 14 matching and connected to the card interface 242 is provided at the bottom of the clamping bin. The connecting mechanism 14 is provided with right-angle pressing pieces 140 on both sides covering the bottom and side of the clamping bin, and the right-angle pressing piece 140 is magnetically fixed to the top platform 24 by the magnetic block 26.
[0057] The capacity of the clamping bin 1 is designed according to production requirements. In conventional production, the number of a group of reed clips 100 is 30 / group or 50 / group. A group of reed clips 100 are directly added to the back-opening clamping bin 1, which is convenient and quick. The front clamping bin is upper-opening and the reed clips 100 need to be put in one by one. It takes 3 to 5 minutes to put a group in. The back-opening clamping bin 1 is designed to be directly added in a group. It only takes 2 to 3 seconds to make the clamping bin 1 full, thereby improving production efficiency.
[0058] Specifically, Fig.12 As shown, in the unfolded state of the clamping compartment 1 of this embodiment, it can be known that the clamping compartment 1 includes a clamping compartment upper cover 11 and a clamping compartment lower cover 12, and the clamping compartment upper cover 11 is connected to one end of the clamping compartment lower cover 12 through an opening and closing mechanism 13, and the end of the clamping compartment upper cover 11 away from the opening and closing mechanism 13 is opened to form a compartment outlet 10, and the end of the clamping compartment lower cover 12 away from the opening and closing mechanism 13 is provided with the connecting mechanism 14, and the clamping compartment lower cover 12 is connected to the clamping cavity of the push-clamp body 2 through the connecting mechanism 14. 40 is clamped, a slide groove (not shown) is provided in the lower cover 12 of the clamping bin, a spring clip 100 is installed in the slide groove, a top clamp mechanism 15 is provided in the slide groove near one end of the opening and closing mechanism 13, the top clamp mechanism 15 can slide back and forth along the slide groove, when the top clamp mechanism 15 slides toward the outlet, the spring clip 100 can be sent to the outlet in place; when the top clamp mechanism 15 slides in the opposite direction, the spring clip 100 can be stably clamped and installed in the slide groove. The above back-opening clamping bin is realized by the opening and closing mechanism 13, which is convenient for the clamping bin to install the spring clip 100, and the spring clip group is placed according to the length of the slide groove in the lower cover 12 of the clamping bin, which can realize fast loading, and at the same time, it can be seen whether the front and back placement directions of the spring clip 100 meet the standard requirements.
[0059] When implementing it, 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, Fig.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.
