Abstract
Description
Technical Field
[0001] This specification relates to the field of hammering device technology, and more specifically, to a quick clamping device for hammerheads of hammer pins. Background Art
[0002] The method of dismantling and assembling derricks by manually swinging a sledgehammer is not only prone to causing physical strain on the workers, but also poses a risk of falls during the hammer-swinging process, and may even result in injury or death.
[0003] Considering the significant threat to personnel posed by the aforementioned disassembly and assembly methods, electric hammers can currently be used for derrick disassembly and assembly. However, the hammerheads of electric hammers are mostly connected by threads, which are easily damaged during hammering, causing the hammerhead to lose its secure fastening force. Moreover, hammerhead replacement is cumbersome, reducing work efficiency. Utility Model Content
[0004] The purpose of this specification is to provide a quick clamping device for hammerheads of hammer pins, which can overcome the defects of existing hammerhead installation methods.
[0005] The embodiments described in this specification are implemented as follows:
[0006] A quick clamping device for hammerheads of a hammer pinner includes a locking nut, a hammerhead, a rubber clamp, and an impact rod.
[0007] The hammerhead has a user end and a connecting end that are arranged opposite to each other. The user end of the hammerhead is used for hammering operations. The locking nut is connected to the connecting end of the hammerhead.
[0008] The two ends of the rubber clamp are respectively disposed at the opposite ends of the locking nut and the connecting end, and the rubber clamp is in a compressed deformation state when the locking nut and the connecting end are connected;
[0009] The impact rod is sleeved inside the rubber clamp along the direction from the locking nut to the hammer head, and the impact rod is in an interference fit with the rubber clamp through the squeezing action of the locking nut on the rubber clamp.
[0010] The embodiments described in this specification have at least the following advantages or beneficial effects:
[0011] Compared with existing technologies, when using the hammer head for hammering operations, the force exerted by the impact rod towards the hammer head can further increase the elastic compression deformation of the rubber clamp, resulting in a better connection between the impact rod and the hammer head. Therefore, the above-mentioned design can effectively prevent the hammer head from falling off due to impact force. Attached Figure Description

[0024] Please refer to Figures 1 to 2 The quick clamping device for hammer head of the hammer pin provided in one embodiment of this specification mainly includes a locking nut 1, a hammer head 2, a rubber clamp 3, and an impact rod 4.
[0025] The hammer head 2 has a user end 22 and a connecting end 21 arranged opposite to each other. The user end 22 of the hammer head 2 is used for hammering operations. The locking nut 1 is connected to the connecting end 21 of the hammer head 2.
[0026] The two ends of the rubber clamp 3 are respectively disposed at the opposite ends of the locking nut 1 and the connecting end 21, and the rubber clamp 3 is in a compressed deformation state when the locking nut 1 is connected to the connecting end 21;
[0027] The impact rod 4 is sleeved inside the rubber clamp 3 along the direction from the locking nut 1 to the hammer head 2, and the impact rod 4 is in an interference fit with the rubber clamp 3 through the squeezing action of the locking nut 1 on the rubber clamp 3.
[0028] In this embodiment, the rubber chuck 3 has a first inclined surface 31 and a second inclined surface 32. The first inclined surface 31 is inclined upward from the locking nut 1 toward the connecting end 21, and the second inclined surface 32 is inclined downward from the locking nut 1 toward the connecting end 21. The first inclined surface 31 abuts against the side of the locking nut 1 near the connecting end 21, and the second inclined surface 32 is embedded in the side of the connecting end 21 near the locking nut 1. The rubber chuck 3 is subjected to the squeezing force of the locking nut 1 on the first inclined surface 31 and is interference-fitted with the impact rod 4.
[0029] In this embodiment, through the connection between the locking nut 1 and the connecting end 21, the rubber clamp 3 disposed between the locking nut 1 and the hammer head 2 is compressed. At this time, the rubber clamp 3 is in an elastic compression state. When the rubber clamp 3 is in a compressed state, it can compress the impact rod 4 sleeved on its inner side, so that the impact rod 4 and the rubber clamp 3 are in an interference fit. The cooperation between the locking nut 1 and the connecting end 21 can limit the rubber clamp 3, thereby making the impact rod 4 and the hammer head 2 maintain a stable connection state.
[0030] Specifically, when using the end 22 of the hammer head 2 for hammering operations, the force exerted by the impact rod 4 on the hammer head 2 can further increase the elastic compression deformation of the rubber clamp 3, making the connection between the impact rod 4 and the hammer head 2 better. It can be seen that the above setting can effectively prevent the hammer head 2 from falling off due to the impact force.
[0031] In this embodiment, the inclination of the first inclined surface 31 is greater than or equal to the inclination of the second inclined surface 32. Specifically, this method allows the locking nut 1 to exert a stronger compressive force on the rubber clamp 3.
[0032] In this embodiment, the locking nut 1 is threadedly connected to the connecting end 21; the locking nut 1 has a tapered hole 11 along the direction from the connecting end 21 to the use end 22, and the connecting end 21 has a tapered groove 23. The groove opening of the tapered groove 23 communicates with the tapered hole 11. The groove channel direction of the tapered groove 23 and the hole channel direction of the tapered hole 11 are both from the connecting end 21 to the use end 22; the hole wall of the tapered hole 11 abuts against the first inclined surface 31, and the groove sidewall of the tapered groove 23 abuts against the second inclined surface 32.
[0033] In this embodiment, the connection position between the locking nut 1 and the connecting end 21 can be determined based on the preset extrusion pressure or the elastic deformation compression of the rubber chuck 3 (or the setting depth of the connecting end 21 in the locking nut 1).
[0034] In this embodiment, a scale can also be set on the connecting end 21 to clearly indicate the connection position between the locking nut 1 and the connecting end 21, making it easier for workers to adapt and adjust the device, thus enhancing its practicality and flexibility.
[0035] In this embodiment, the tapered hole 11 and tapered groove 23 are provided to match the above-mentioned threaded connection, so as to adjust the elastic deformation of the rubber chuck 3 by tightening the locking nut 1.
[0036] In other embodiments, the locking nut 1 can also be connected to the connecting end 21 by a snap-fit, and the first inclined surface 31 can also abut against the side wall of the prism hole (position corresponding to the conical hole 11), and the second inclined surface 32 can also abut against the prism groove (position corresponding to the conical groove 23) to achieve the effect of the locking nut 1 pressing against the first inclined surface 31.
[0037] In this embodiment, the locking nut 1 has a connecting groove 12, which is adapted to the connecting end 21. The connecting groove 12 is connected to the outer wall of the connecting end 21 by a thread. The bottom of the connecting groove 12 communicates with the tapered hole 11, and the second inclined surface 32 of the rubber clamp 3 can pass through the bottom of the connecting groove 12.
[0038] In this embodiment, the groove opening of the connecting groove 12 faces the location of the connecting end 21, and the bottom wall of the connecting groove 12 is provided with a hole. The connecting groove 12 communicates with the tapered hole 11 through the hole, and the hole can pass through the second inclined surface 32 and abut against the position with the highest slope of the second inclined surface 32.
[0039] In this way, when disassembling the hammer head 2, simply ensure that the locking nut 1 and the connecting end 21 are not connected to remove the hammer head 2 for easy replacement or storage.
[0040] In this embodiment, an annular groove 33 is provided at the connection position of the first inclined surface 31 and the second inclined surface 32, and a positioning platform 13 is provided between the bottom wall of the connecting groove 12 and the tapered hole 11, and the position of the positioning platform 13 corresponds to the position of the annular groove 33.
[0041] During installation, the installation accuracy of the above-mentioned device can be effectively improved by determining the positions of the positioning platform 13 and the annular groove 33.
[0042] In this embodiment, the rubber chuck 3 has a mounting through hole along its central axis. One end of the impact rod 4 can pass through the mounting through hole and abut against the bottom wall of the tapered groove 23. The rubber chuck 3 and the impact rod 4 are interference-fitted through the mounting through hole. Specifically, the wall of the mounting through hole abuts against the outer wall of the impact rod 4, and one end of the impact rod 4 abuts against the bottom wall of the tapered groove 23 through the mounting through hole, which further enhances the interference fit and prevents the hammer head 2 from falling off.
[0043] In this embodiment, the position of the second inclined surface 32 away from the first inclined surface 31 within the hammer head 2 is set according to the size of the hammer head 2.
[0044] In this embodiment, the dimensions of the hammer head 2 can be the size or weight of the hammer head 2.
[0045] In this embodiment, the locking nut 1, the rubber clamp 3, the hammer head 2, and the impact rod 4 have the same central axis or rotation axis.
[0046] In this embodiment, the outer diameter of the locking nut 1 is the same as the outer diameter of the working end 22 of the hammer head 2. This design ensures the overall consistency of the device, facilitating storage and placement. Furthermore, by standardizing the size of the locking nut 1, it is suitable for various types of hammer heads 2.
[0047] The above are merely preferred embodiments of this specification and are not intended to limit this specification. Various modifications and variations can be made to this specification by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this specification should be included within the scope of protection of this specification.
