Abstract
Description
Technical Field
[0001] This invention relates to the field of hammer-driven sleeve technology, specifically a universal guided hammer-driven sleeve. Background Technology
[0002] An impact hammer, also known as a force hammer, consists of a hammer body and a dynamic force sensor. It is another commonly used excitation device in modal testing, besides the vibrator. Its advantage is that it is not connected to the specimen, does not add any mass to the structure, and therefore does not affect the dynamic characteristics of the specimen. The energy level and frequency range of the excitation force depend on the magnitude of the operator's force, the mass of the hammer, the hardness of the hammerhead, and the plasticity of the impact point on the structure. Impact hammers are particularly suitable for lightweight, relatively rigid structures (such as compressor blades, sheet metal parts, printed circuit boards, etc.). The heavy weight of the hammer body and the softness of the hammer head result in a longer contact time, which can excite a lower frequency. In extreme cases, the hammering method can excite heavy structures with very low resonant frequencies, such as buildings, trains, ships, foundations, and bridges. The hammering sleeve is a type of impact hammer accessory. A search revealed that a typical sleeve in the prior art is an impact sleeve published in CN113524089A, which includes: a first cylinder and a second cylinder connected to each other. The first cylinder has a nut connection hole along the axial direction for connecting with a nut to be removed. The diameter of the nut connection hole gradually decreases from the outside to the inside. At least one shearing part with a triangular cross-section is formed on the nut connection hole, and the cross-section of the shearing part gradually increases from the outside to the inside. The second cylinder includes a limiting platform, a hexagonal prism, and an impact head connected in sequence. The limiting platform is connected to the first cylinder. The diameter of the limiting platform is larger than the diameter of the first cylinder and larger than the diameter of the circumcircle of the hexagonal prism. The diameter of the impact head is smaller than the diameter of the circumcircle of the hexagonal prism. Its main feature is that by clamping the nut with a socket, applying impact force, and rotating it with tools such as a wrench, the damaged nut can be removed.
[0003] In summary, the current impact hammer tool sleeve cannot meet the requirements for installing / removing stepped pins embedded in deep holes. In the past, the manual assembly and removal of such parts in the industry was quite cumbersome. In other words, the efficiency of continuous assembly industry is constrained by process bottlenecks, resulting in resource waste. To address the above issues, it is necessary to improve the existing equipment. Summary of the Invention
[0004] The purpose of this invention is to provide a universal guided hammer sleeve to solve the problem that the current impact hammer tool sleeves mentioned in the background art cannot meet the requirements for installing / removing stepped pins embedded in deep holes. In the past, the manual assembly and removal of such accessories in the industry was quite troublesome.

At the same time, the sleeve assembly body is connected to the impact hammer assembly.

[0010] Preferably, both the first support frame and the second support frame are semi-circular rings, and the inner walls of the first support frame and the second support frame are attached to the parts of the impact hammer body connected to the impact hammer assembly.
[0011] Preferably, the first support frame and the second support frame have slots on their side walls, and the slots are distributed in a rectangular array.
[0012] Preferably, an auxiliary handle is threadedly connected to one end face of the first support frame and the second support frame, and the auxiliary handle is positioned above the main body of the impact hammer.
[0013] Preferably, the auxiliary blowing mechanism includes a movable ring, a forked rod, a fixed disc, a telescopic airbag, a one-way exhaust valve, a one-way intake valve, a pad, and a locking block. The movable ring is connected to the fixed disc via the forked rod, and the forked rod and the fixed disc are fixedly connected to the pad via the telescopic airbag. The forked rod is distributed in a ring array on the movable ring.

[0017] Compared with the prior art, the beneficial effects of the present invention are: this universal guided hammering sleeve,
[0018] (1) This invention effectively solves the problem that current impact hammer tool sleeves cannot meet the requirements for installing / removing embedded deep-hole stepped pins by using a sleeve assembly body, a storage spring, a secondary impact hammer, and an embedded concealed punch rod in combination. Previously, the manual assembly and removal of such parts was cumbersome, resulting in efficiency bottlenecks in continuous assembly processes and wasting resources. When the impact hammer body drives the impact hammer assembly for impact operations, the storage spring inside the sleeve assembly body connected to it transmits force to the embedded concealed punch rod via the secondary impact hammer for driven hammering operations. This utilizes a mechanical secondary... The transmission of secondary force, through the amplitude hammer, solves the problem of assembling and removing deep-hole stepped pins under relatively simple and stable mechanism principle conditions. At the same time, the simple amplitude hammer combination meets the function of assembling and removing deep-hole stepped pins of different sizes. Thus, it overcomes the gap in the market where there is no breakthrough mechanism component that is simple and stable, such as the lack of a "universal guided hammer sleeve" combination tool. In addition, its design feature of being able to be used alone or in multiple combinations is not limited by the installation size and has good versatility. That is, it can effectively solve the problem of automated assembly time, reduce the trouble of manual assembly, and is relatively convenient to operate.
[0019] (2) The present invention can effectively solve the problem that most existing impact hammers are supported on one side, i.e., the control handle is held with one hand, and the force surface is singular, making operation inconvenient. The operator can use the limiting component to fix the first support frame and the second support frame on the impact hammer body near the impact hammer assembly. Then, the auxiliary handle is threaded to one side of the first support frame and the second support frame. Thus, when performing impact operation, the other hand that is not holding the control handle can hold the auxiliary handle for support. That is, the force of double-sided support is used to replace the force of single-sided support, thereby optimizing the structure of the device, reducing the difficulty of operation, and avoiding occupational hand diseases caused by trying single-handed operation.
[0020] (3) The present invention can effectively solve the problem that the existing impact hammer body is prone to dust or debris falling due to high-frequency impact during impact operation, which can cause damage to the operator's eyes and pose a great construction safety hazard, namely, falling from height, accidental contact with live electricity, and sharp objects. The worker can insert the moving ring through the sleeve assembly body from right to left and lock it onto the end face of the impact hammer assembly. Then, the locking block on the pad is threaded into the slot. Thus, when the impact hammer assembly is performing impact operation, the moving ring can be moved synchronously. When the moving ring moves, it will drive the fixed disc to reciprocate to compress and stretch the telescopic airbag through the forked rod. The gas inside the compressed telescopic airbag will be discharged to the work point, i.e. the work position where the hidden impact rod is embedded, through the one-way exhaust valve. Thus, the airflow can be used to blow away the pollutants generated at the work point, preventing them from entering the operator's eyes and thus enriching the functionality of the device and improving the safety during operation.
