Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to a cyclic reciprocating hammering device. Background Art

[0002] The release and hammering action under tension is typically achieved through a linkage, gear mechanism, or a mechanism combining a locking lever and a hook. Linkage mechanisms require transmission through intermediate components, resulting in a long transmission path, large error accumulation, and low mechanical efficiency. During linkage movement, the center of mass of both the connecting rod and the slider undergo variable speed motion, generating inertial forces that are difficult to eliminate using standard balancing methods, increasing the dynamic load on the mechanism. Therefore, linkage mechanisms are not suitable for high-speed motion. Gear mechanisms are relatively compact and more stable than linkages, but they still require higher manufacturing and assembly processes and are not suitable for applications with longer travels. While a mechanism consisting of a locking lever and a rotatable hook is compact, easy to manufacture, and stable, it cannot achieve a repetitive "charge-release" cycle.

[0003] Currently, there are few reciprocating release devices that combine a compact structure, low manufacturing requirements, and a large storage stroke. Most devices can only complete a single release action, or, while they can perform a "charge-release" cycle, they suffer from low mechanical efficiency, poor stability, and high manufacturing requirements.

[0017] Preferably, the second arc surface of the cam is tangent to the abutting cylinder and the abutting surface in sequence.

[0018] (3) Beneficial effects

[0019] Compared with the prior art, the present invention provides a cyclic reciprocating hammering device with the following beneficial effects:

[0020] The cyclic reciprocating hammering device is used in conjunction with the hammer body, return spring, guide rail, hook and driving device. In the ungrasping stage, the hook is located in the empty release groove, the cam rotates clockwise, the second arc surface contacts the top surface, and the cam transmission rod is pushed from right to left. At this time, the hook moves to the left under the push of the cam transmission rod. The hook makes the contact surface contact the upper top surface of the trapezoidal boss through the rounded corner, and restricts the rotation of the hook until the hook is pushed into the empty grasping groove (such as Figure 7 As shown), at this time, the fitting surface is separated from the upper surface of the trapezoidal platform. Since the embedded rod applies pressure to the lower left side of the hook, the hook rotates counterclockwise around the stepped axis at a small angle, causing the embedded rod to fall into the hook groove, completing the capture of the hammer body.

[0021] During the pulling and releasing phase, after the hammer is caught, the cam continues to rotate clockwise, and the second arc surface changes to contact with the abutting cylinder, moving the cam transmission rod from left to right. The contact surface of the hook continues to contact with the upper surface of the trapezoidal boss, preventing the embedded rod from falling out of the hook slot during the pulling process, until the hook is pulled into the empty release slot (such as Figure 8 As shown in the figure, the stepped shaft on the hook moves to the rightmost end of the waist-shaped groove, and the second arc surface rotates approximately 170°. As the second arc surface continues to rotate, it drives the cam transmission rod to the right for a distance. The inserted shaft drives the hook to rotate counterclockwise around the stepped shaft a certain angle, allowing the embedded rod to break free from the hook groove. Because the return spring is compressed during the process of pulling the hammer head to the right, when the embedded rod is released from the hook groove, the return spring returns to its original position, striking the hammer head to the left, thus releasing the hammer. The right side then enters the de-grasping stage, and the cycle repeats.

[0022] As a result, the device occupies a small space, has high device stability, high mechanical efficiency, and low process requirements, making it easy to achieve a cyclic "storage-release" effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figure 1-8, a cyclic reciprocating hammering device, including a guide rail 3, which serves as a support and guiding structure for the entire device, ensuring that all movable parts such as the hammer body 1 and the hook 4 can slide stably and smoothly along a predetermined path. The hammer body 1 is a device used for hammering in the device. The hammer body 1 is slidably set on one side of the guide rail 3, and a return spring 2 is provided between the hammer body 1 and one side of the guide rail 3. The return spring 2 is the power source for the hammer body 1 to hammer. The hook 4 is slidably set on the guide rail 3, and the hook 4 can reciprocate back and forth. The reciprocating movement of the hook 4 is used to grab and release the hammer body 1. When the hook 4 approaches the hammer body 1, the hook 4 grabs the hammer body 1 and drives the hammer body 1 to compress the return spring 2. When the return spring 2 is compressed to the limit, the hook 4 releases the hammer body 1, and the hammer body 1 is ejected by the return spring 2.

[0034] The guide rail 3 includes a side plate 31, which serves as the main body of the guide rail 3 and provides a platform for mounting and supporting other components, such as baffle 1 32, baffle 2 37, and waist groove 35. A baffle 1 32, perpendicular to the side plate 31, and a slide groove 1 321 are provided on baffle 1 32. Slide groove 1 321 is used to mount the hammer rod 12 and restrict and guide the sliding of the hammer rod 12. Baffle 1 32 and hammer head 11 also serve to limit the position of the return spring 2. A baffle 2 37, perpendicular to the side plate 31, is provided in the middle of the side plate 31. Baffle 2 37 is provided on baffle 2 37. Slide groove 2 371 is used to mount the cam transmission rod 5 and restrict and guide the sliding of the cam transmission rod 5. A waist-shaped groove 35 is provided on the side plate 31 between the baffle 1 32 and the baffle 2 37 . The stepped shaft 42 of the hook 4 is installed in the waist-shaped groove 35 . The waist-shaped groove 35 can limit and guide the reciprocating motion of the hook 4 .

[0035] The hammer body 1 includes a hammer head 11, which is the primary component for performing the hammering action. It is typically made of a hard, wear-resistant material to deliver sufficient impact force during the strike. A hammer rod 12 is mounted on the hammer head 11, which slides within a slide groove 321. The hammer rod 12 connects the embedded rod 13 and the hammer head 11. An embedded rod 13 is mounted at the end of the hammer rod 12, one end of which slides within a waist-shaped groove 35. The waist-shaped groove 35 restricts and guides the sliding of the embedded rod 13, ensuring greater stability during the hammering action. Furthermore, the embedded rod 13 facilitates the hook 4's grip. A return spring 2 is positioned between the hammer head 11 and the baffle 32. When the embedded rod 13 is gripped and pulled, the hammer head 11 moves rightward, compressing the return spring 2. When the embedded rod 13 is released, the return spring 2 resets, ejecting the hammer head 11 for the strike.

[0036] Below the waist groove 35 on the side panel 31 is a trapezoidal boss 34. The boss 34 is a raised, trapezoidal portion located below the waist groove 35. Flanking either side of the boss 34 are a first inclined surface 341 and a second inclined surface 342. A hollow gripping groove 33 is formed between the first inclined surface 341 and the first baffle 32, while a hollow release groove 38 is formed between the second inclined surface 342 and the second baffle 37. The first inclined surface 341 and the second inclined surface 342 create hollow gripping grooves 33 and hollow release grooves 38, respectively, between the boss 34 and the first baffle 32 and the second baffle 37. When the hook 4 reaches the hollow gripping groove 33, it needs to rotate counterclockwise a certain angle. The hollow gripping groove 33 provides space and position for the hook 4 to rotate. When the hook 4 reaches the hollow release groove 38, it also needs to rotate counterclockwise a certain angle to release the embedded rod 13. The hollow release groove 38 also provides space and position for the hook 4 to rotate. Secondly, the first inclined surface 341 and the second inclined surface 342 allow the fitting surface 44 at the bottom of the hook body 46 to separate from the upper top surface of the trapezoidal boss 34 when entering the empty grabbing groove 33 and the empty release groove 38, so that the hook body 46 can rotate around the stepped shaft 42 to a certain extent and complete the corresponding rotation action.

[0037] The hook 4 includes a hook body 46, which is the main body of the hook 4 and is equipped with various components. The hook body 46 is provided with a hook groove 41, which is used to hook the embedded rod 13. A stepped shaft 42 is provided on one side of the hook body 46. The stepped shaft 42 has two layers, and the diameter of the inner part is larger than the diameter of the outer part. The inner diameter is also larger than the diameter of the waist-shaped groove 35. During installation, the outer diameter of the stepped shaft 42 is installed in the waist-shaped groove 35, and the inner diameter is pressed against the side plate 31, which plays a role in fixing and limiting the hook 4. The other side of the hook body 46 is provided with a mounting shaft 1 43 corresponding to the stepped shaft 42. The mounting shaft 1 43 is used to be installed on the external shell, completely fixing the entire hook 4 and ensuring its stable sliding. A second mounting hole 47 is also provided on the hook body 46. The second mounting hole 47 is used to install the insertion shaft 52 of the cam transmission rod 5. When the hook 4 moves to the empty grabbing groove 33 and the empty release groove 38, the hook body 46 needs to rotate to a certain extent to realize the grabbing and releasing actions. At this time, the rotation center of the hook body 46 is the stepped shaft 42. When in the empty grabbing groove 33, the pressure of the embedded rod 13 on the left side of the hook body 46 causes the hook body 46 to rotate. When in the empty release groove 38, since the stepped shaft 42 has reached the rightmost side of the waist-shaped groove 35, and as the second arc surface 63 of the cam 6 continues to rotate, the insertion drawer continues to move a distance to the right to drive the hook body 46 to rotate around the stepped shaft 42. A fitting surface 44 is provided at the bottom of the hook body 46. When the hook body 46 is located on the trapezoidal boss 34, the fitting surface 44 is completely fitted on the upper top surface of the trapezoidal boss 34, ensuring the overall posture of the hook 4 so that the embedded rod 13 is restricted in the hook groove 41 and will not fall out.

[0038] A rounded corner 45 is provided on one side of the fitting surface 44. After the hook 4 is located in the empty release groove 38 and the hammer body 1 is released, the hook 4 needs to be pushed back to the empty grabbing groove 33. At this time, the rounded corner 45 is used for transition. In order to ensure that the fitting surface 44 slides smoothly on the upper top surface of the trapezoidal boss 34, the resistance of the hook body 46 when entering the trapezoidal boss 34 is reduced.

[0039] A driving device 7 is provided on the other side of the guide rail 3, and the driving device 7 includes a cam transmission rod 5 and a cam 6. The cam transmission rod 5 is used to drive the hook 4 to move left and right to realize the grabbing and releasing action, and the cam 6 drives the cam transmission rod 5 to move back and forth.

[0040] The cam transmission rod 5 slides in the second slide groove 371, which serves to limit and guide the sliding of the cam transmission rod 5. The cam transmission rod 5 is provided with a third slide groove 51, which is half the length of the cam transmission rod 5 and is used to mount the second mounting shaft 61 on the cam 6. The length of the third slide groove 51 is greater than the diameter of the second arc surface 63. Since the second arc surface 63 of the cam 6 needs to contact the abutting surface 54 and the abutting cylinder 53 in sequence during the rotation of the cam 6, the second arc surface 63 of the cam 6 contacts the abutting cylinder 53 during the pull-to-release process, and the second arc surface 63 of the cam 6 contacts the abutting surface 54 during the release process.

[0041] The side plate 31 is further provided with a mounting hole 36. The mounting hole 36 is used to mount the cam 6, and a motor is further provided on the outside to drive the cam 6 to rotate.

[0042] Cam 6 includes a first arcuate surface 62 and a second arcuate surface 63. The angles of the first and second arcuate surfaces 62 and 63 are both 180°. The diameter of the first arcuate surface 62 is smaller than that of the second arcuate surface 63. Cam 6 also includes a second mounting shaft 61, which is rotatably assembled within the first mounting hole 36 and disposed within the third slide groove 51 of the cam transmission rod 5. The second arcuate surface 63 serves primarily as a support, allowing the cam transmission rod 5 to move left and right.

[0043] Working principle: In the de-grasping stage, the hook 4 is located in the empty release groove 38, the cam 6 rotates clockwise, the second arc surface 63 contacts the top surface 54, and the cam transmission rod 5 is pushed from right to left. At this time, the hook 4 moves to the left under the push of the cam transmission rod 5, and the hook 4 makes the contact surface 44 contact the upper top surface of the trapezoidal boss 34 through the rounded corner 45, and restricts the rotation of the hook 4 until the hook 4 is pushed into the empty grasping groove 33. Figure 7As shown, at this time, the fitting surface 44 is separated from the upper top surface of the trapezoidal platform. Since the embedded rod 13 applies pressure to the lower left side of the hook 4, the hook 4 rotates counterclockwise around the stepped axis 42 by a small angle, so that the embedded rod 13 falls into the hook groove 41, completing the capture of the hammer body 1.

[0044] During the pulling and releasing stage, after the hammer 1 is captured, the cam 6 continues to rotate clockwise, and the second arc surface 63 changes to contact with the abutting cylinder 53, moving the cam transmission rod 5 from the left to the right. The contact surface 44 of the hook 4 continues to contact the upper surface of the trapezoidal boss 34, preventing the embedded rod 13 from falling out of the hook groove 41 during the pulling process, until the hook 4 is pulled into the empty release groove 38. Figure 8 As shown, the stepped shaft 42 on the hook 4 moves to the rightmost end of the waist-shaped groove 35, and the second arc surface 63 rotates approximately 170°. As the second arc surface 63 continues to rotate, it drives the cam transmission rod 5 to the right for a certain distance. The insertion shaft 52 drives the hook 4 to rotate counterclockwise around the stepped shaft 42 by a certain angle, allowing the embedded rod 13 to break free from the restraint of the hook groove 41. Because the return spring 2 is compressed during the process of pulling the hammer head 11 to the right, when the embedded rod 13 is released from the hook groove 41, the return spring 2 recovers, hammering the hammer head 11 to the left, thereby releasing the hammer body 1. The right side then enters the de-grasping stage, and the cycle repeats.

[0045] As a result, the device occupies a small space, has high device stability, high mechanical efficiency, and low process requirements, making it easy to achieve a cyclic "storage-release" effect.
