A bidirectional floating clamping mechanism

Abstract

A bidirectional floating clamping mechanism comprises an upper die assembly. The upper die assembly comprises an upper die seat, a movable rod, a driving rod, a limiting shaft, a second rotating shaft and a locking piece. The upper die seat is provided with a movable hole and a sliding groove. The driving rod is movably inserted into the sliding groove and passes through the movable rod. The locking piece passes through the groove and has a hook-shaped structure. One end of the locking piece is rotatably arranged on the second rotating shaft, and the other end is rotatably provided with a floating head. When the movable rod is pressed down, the locking piece is rotated with the second rotating shaft as the rotation point, so that the oblique end provided with the floating head moves. The two movements are not required to continue, the movement steps are reduced, and the clamping is faster. Meanwhile, the floating head has a U-shaped structure and is rotatably arranged at one end of the locking piece. After the floating head touches the coil framework, the floating head can be slightly rotated to completely fit the floating head with the coil framework, so as to ensure the stability of the clamping.

Description

Technical Field

[0001] This invention relates to the field of winding machine technology, and in particular to a bidirectional floating clamping mechanism. Background Technology

[0002] A coil typically refers to a loop of wire. The most common applications of coils include motors, inductors, transformers, and loop antennas. During coil winding, the two ends of the coil frame need to be fixed, and then the winding continues by rotation. Existing clamping mechanisms include... Figure 7 As shown, the locking element is pressed down by a crossbar with bearings at both ends, and then pushed to one side to make it fit tightly against the coil frame, thus fixing the coil frame. However, this method requires the locking element to move in two steps: first pressing down to extend it, and then moving horizontally to fit tightly against the coil frame. The steps are cumbersome, and because of the two-step movement, two drive devices are needed to drive the pressing down and the horizontal movement respectively, making the structure relatively complex. Summary of the Invention

[0003] In view of this, the present invention provides a bidirectional floating clamping mechanism to solve the above-mentioned technical problems.

[0004] A bidirectional floating clamping mechanism. The bidirectional floating clamping mechanism includes an upper mold assembly, which includes an upper mold base, a movable rod inserted into the upper mold base, a drive rod inserted into the movable rod, a limiting shaft disposed on the movable rod, a second rotating shaft inserted into the upper mold base, and a locking member rotatably disposed on the second rotating shaft. The upper mold base has a through-hole for accommodating the movement of the movable rod and a sliding groove for accommodating the movement of the drive rod. One end of the movable rod has a limiting block, and the other end has a groove with the limiting shaft inserted into it. Both ends of the drive rod are movably inserted into the sliding groove and pass through the movable rod. The second rotating shaft is located on one side of the sliding hole. The locking member passes through the groove and has a hook-shaped structure. One end of the locking member is rotatably disposed on the second rotating shaft, and the other end has a floating head rotatably disposed thereon. The floating head has a U-shaped structure and is rotatably mounted on one end of the locking member. When the movable rod is pressed down, it will drive the locking member to rotate around the second pivot, causing the end with the floating head to move obliquely.

[0005] Furthermore, the upper mold assembly also includes a first rotating shaft inserted into the upper mold base, an upper fixed seat disposed on the first rotating shaft, and a first spring sleeved on the movable rod.

[0006] Furthermore, the first rotating shaft is located at the bottom end of the upper mold base and is used to set the upper fixed seat. One end of the upper fixed seat is set on the first rotating shaft, and the upper fixed seat is provided with a second fixing port.

[0007] Furthermore, an extension portion extending toward the center of the movable hole is provided on the inner sidewall of the movable hole, and one end of the first spring abuts against the limiting block, and the other end abuts against the extension portion.

[0008] Furthermore, the central axis of the movable hole is parallel to the central axis of the upper mold base, the central axis of the sliding groove is perpendicular to the central axis of the movable hole and extends in a direction parallel to the central axis of the movable hole, and the sliding groove is connected to the movable hole.

[0009] Furthermore, a second spring is provided between the locking member and the movable rod, with one end of the second spring abutting against the bottom end of the groove and the other end abutting against the locking member.

[0010] Furthermore, the bidirectional floating clamping mechanism also includes a lower mold assembly and a wire clamp assembly disposed on the upper mold assembly, wherein the lower mold assembly is provided with a first fixing port facing the upper mold assembly.

[0011] Furthermore, the wire clamp assembly includes a fixed block disposed on the upper mold base, a movable rod movably inserted on the fixed block, and a third spring sleeved on the movable rod. The fixed block has a through hole and a first clamping block disposed at the opening of the through hole. One end of the movable rod is provided with a second clamping block, and the other end is provided with a disc. One end of the third spring abuts against the disc, and the other end abuts against the opening of the through hole.

[0012] Compared with the prior art, the bidirectional floating clamping mechanism provided by the present invention has a limiting block at one end of the movable rod and a groove at the other end with the limiting shaft inserted therein. One end of the first spring abuts against the limiting block, and the other end abuts against the extension. The drive rod is inserted into the movable rod and the sliding groove. The locking member has a hook-shaped structure, with one end rotatably mounted on the second rotating shaft and the other end rotatably mounted with a floating head. When the drive rod is pressed down, it drives the locking member to rotate around the second rotating shaft, causing the end of the locking member with the floating head to press tightly against the coil frame, thus fixing the coil frame. In this way, the movement trajectory of the end of the locking member with the floating head is an oblique movement, eliminating the need for two additional movements, reducing the number of movement steps, and achieving faster and more precise operation. It also reduces the number of external drive devices, requiring only one to achieve the desired result. Meanwhile, to ensure a perfect fit, the floating head has a U-shaped structure and is rotatably mounted at one end of the locking member. After the floating head touches the coil frame, it can rotate slightly to make the floating head fit perfectly with the coil frame, ensuring the stability of the clamping.

[0019] Figure 7 This is a schematic diagram of the clamping mechanism in the prior art. Detailed Implementation

[0020] The following provides a more detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0021] like Figures 1 to 6 The diagram shows a schematic representation of the bidirectional floating clamping mechanism provided by this invention. The bidirectional floating clamping mechanism includes a lower mold assembly 10, an upper mold assembly 20, and a wire clamp assembly 30 disposed on the upper mold assembly 20. It is conceivable that the bidirectional floating clamping mechanism also includes other functional modules, such as connecting components, sensors, and mounting components, etc., which are technologies well known to those skilled in the art and will not be described in detail here.

[0022] The lower mold assembly 10 is connected to an external rotating device and rotates under its drive. The lower mold assembly 10 is provided with a first fixing port 11 facing the upper mold assembly 20. One end of the coil frame is inserted into the first fixing port 11. The coil frame is strip-shaped and rotates after being fixed, thereby winding the wire around the coil frame. The coil frame should be existing technology and will not be described in detail here.

[0023] The upper mold assembly 20 includes an upper mold base 21, a first rotating shaft 22 inserted into the upper mold base 21, an upper fixed seat 23 disposed on the first rotating shaft 22, a movable rod 24 inserted into the upper mold base 21, a drive rod 25 inserted into the movable rod 24, a limiting shaft 26 disposed on the movable rod 24, a second rotating shaft 27 inserted into the upper mold base 21, a locking member 28 rotatably disposed on the second rotating shaft 27, and a first spring 29 sleeved on the movable rod 24.

[0024] The upper mold base 21 is cylindrical and connected to an external rotating device, rotating under its drive. The upper mold base 21 has a through-hole 211 for accommodating the movement of the movable rod 24, and a sliding groove 212 for accommodating the movement of the drive rod 25. The central axis of the movable hole 211 is parallel to the central axis of the upper mold base 21, and an extension 213 extending towards the center of the movable hole 211 is provided on the inner wall of the movable hole 211. The central axis of the sliding groove 212 is perpendicular to the central axis of the movable hole 211 and extends parallel to the central axis of the movable hole 211; the sliding groove 212 communicates with the movable hole 211.

[0025] The first rotating shaft 22 is located at the bottom of the upper mold base 21 and is used to set the upper fixing seat 23. One end of the upper fixing seat 23 is set on the first rotating shaft 22. The upper fixing seat 23 is provided with a second fixing port 231 facing the lower mold assembly 10. The other end of the coil frame is inserted into the second fixing port 231.

[0026] One end of the movable rod 24 is provided with a limiting block 241, and the other end is provided with a groove 242 into which the limiting shaft 26 is inserted. One end of the first spring 29 abuts against the limiting block 241, and the other end abuts against the extension 213, thereby moving the movable rod 24 upward away from the lower mold assembly 10 through the elastic force of the first spring 29.

[0027] The drive rod 25 is movably inserted into the sliding groove 212 at both ends and passes through the movable rod 24. When the external drive device presses down on the drive rod 25, it can cause the drive rod 25 to slide within the sliding groove 212, thereby pressing down on the movable rod 24 and compressing the first spring 29. After the external drive device resets, the spring force causes the movable rod 24 to automatically reset. Bearings are fitted at both ends of the drive rod 25. Since the winding needs to rotate while being pressed down, the bearings reduce friction with the external drive device during rotation.

[0028] The second rotating shaft 27 is positioned to one side of the movable hole 211. The locking member 28 passes through the groove 242 and has a hook-shaped structure. One end of the locking member 28 is rotatably mounted on the second rotating shaft 27, and the other end is rotatably mounted with a floating head 281. When the drive rod 25 is pressed down, it drives the locking member 28 to rotate around the second rotating shaft 27, thereby causing the end of the locking member 28 with the floating head 281 to be tightly attached to the coil frame to fix the coil frame. In this way, the movement trajectory of the end of the locking member 28 with the floating head 281 is an oblique movement, eliminating the need for two additional movements, reducing the number of movement steps, and achieving faster and more precise operation. It also reduces the number of external drive devices required, requiring only one to achieve the desired result.

[0029] The floating head 281 has a U-shaped structure and is rotatably disposed at one end of the locking member 28. Since the movement trajectory of the locking member 28 with the floating head 281 is oblique, it is difficult to completely fit with the coil frame. Therefore, after the floating head 281 touches the coil frame, it can be slightly rotated to make the floating head 281 completely fit with the coil frame, ensuring the stability of clamping.

[0030] A second spring 210 is also provided between the locking member 28 and the movable rod 24. One end of the second spring 210 abuts against the bottom end of the groove 242, and the other end abuts against the locking member 28. When the locking member 28 fixes the coil frame, it is driven by an external driving device, which can easily cause excessive force and damage to the coil frame. The second spring 210 can provide a certain buffering effect when the locking member 28 has already abutted against the coil frame and the movable rod 24 is still applying pressure, thereby reducing the pressure on the locking member 28 and improving stability.

[0031] The wire clamp assembly 30 includes a fixed block 31 disposed on the upper mold base 21, a movable rod 32 movably inserted on the fixed block 31, and a third spring 33 sleeved on the movable rod 32.

[0032] The fixing block 31 is fixed to the upper mold base 21 by fasteners such as screws. The fixing block 31 has a through hole 311 and a first clamping block 312 disposed at the opening of the through hole 311. One end of the moving rod 32 is provided with a second clamping block 321, and the other end is provided with a disc 322. One end of the third spring 33 abuts against the disc 322, and the other end abuts against the opening of the through hole 311. The elastic force of the third spring 33 moves the second clamping block 321 closer to the first clamping block 312, thereby clamping them together to hold the wire. When it is necessary to release the wire, by pushing the end of the moving rod 32 with the disc 322, the second clamping block 321 is moved away from the first clamping block 312, and the third spring 33 is compressed, thus releasing the wire.

[0033] Compared with the prior art, the bidirectional floating clamping mechanism provided by the present invention has a limiting block 241 at one end of the movable rod 24 and a groove 242 at the other end, into which the limiting shaft 26 is inserted. One end of the first spring 29 abuts against the limiting block 241, and the other end abuts against the extension 213. The drive rod 25 is inserted into the movable rod 24 and the sliding groove 212. The locking member 28 has a hook-shaped structure, with one end rotatably mounted on the second rotating shaft 27 and the other end rotatably mounted with a floating head 281. When the drive rod 25 is pressed down, it drives the locking member 28 to rotate around the second rotating shaft 27, causing the end of the locking member 28 with the floating head 281 to press tightly against the coil frame to fix the coil frame. Thus, the movement trajectory of the end of the locking member 28 with the floating head 281 is oblique, eliminating the need for two further movements, reducing movement steps, and achieving faster and more precise operation. It also reduces the number of external drive devices, requiring only one to achieve the desired result. Meanwhile, to ensure a perfect fit, the floating head 281 has a U-shaped structure and is rotatably mounted at one end of the locking member 28. After the floating head 281 touches the coil frame, it can be slightly rotated to make the floating head 281 fit perfectly with the coil frame, ensuring the stability of the clamping.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions or improvements within the spirit of the present invention are covered within the scope of the claims of the present invention.
