Description

Technical Field

[0001] This utility model relates to the field of hammer technology, specifically a lightweight, high-strength, shock-resistant assembly hammer. Background Technology

[0002] In modern industrial production and various assembly operations, the assembly hammer is a basic and critical tool. Its performance directly affects work efficiency, product quality, and the work experience and health of operators. As the manufacturing industry continues to move towards high precision, high efficiency, and high reliability, more stringent requirements are being placed on the performance of the assembly hammer.

[0003] A patent with the existing authorization announcement number "CN214924104U" discloses a combined shock-absorbing hammer. The shock-absorbing hammer includes a hammer handle, a bushing, a first striking body, and a second striking body. The bushing is welded to the hammer handle, and a disc spring is placed inside the bushing hole. The first and second striking bodies are placed at both ends of the bushing, and their smaller ends are hollow cavities containing cylindrical nylon blocks. The two are connected by rivets. This patent connects the two striking bodies through the disc spring and the nylon body, which can improve the striking intensity and absorb the impact, reduce the impact force on the hand, and the striking bodies can be replaced after wear, reducing the cost of use.

[0004] However, this device has the following shortcomings:

[0005] The aforementioned traditional hand hammers often have a simple structure and lack effective shock absorption design. When striking, the strong vibrations generated will be transmitted to the operator's hand through the handle without any buffering. Long-term use may cause occupational diseases such as hand joint damage and muscle fatigue.

[0006] During the assembly of precision components in electronic devices, excessive vibration can not only injure operators, but may also be transmitted to the components being assembled, causing damage to the components or affecting the assembly accuracy. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 The present invention provides an embodiment of a lightweight, high-strength, shock-resistant assembly hammer, comprising a hammer handle assembly 1, a hammer head assembly 2 disposed on the top of the hammer handle assembly 1, and a buffer head assembly 3 disposed on one side of the hammer head assembly 2.

[0028] The hammer handle assembly 1 includes a hammer handle 11, a buffer groove 12, a buffer pad 13, and a socket 14. Limiting blocks are provided on both sides of the hammer handle 11 to limit the length of the hammer handle 11 inserted into the mounting groove 22, making it easy to align the through hole 24 with the socket 14. A buffer groove 12 is provided on the inner side of the hammer handle 11, and a buffer pad 13 is provided on the inner side of the buffer groove 12. A socket 14 is provided on the top of one side of the hammer handle 11. A handle is provided on the bottom of the outer side of the hammer handle 11, and the handle is made of polyurethane material, which improves the comfort of holding the hand and can also buffer the vibration of the hand.

[0029] The hammer head assembly 2 includes a hammer body 21, a mounting groove 22, a fixing groove 23, and a through hole 24. The hammer body 21 is located at the top of the hammer handle assembly 1. The mounting groove 22 is provided on the inner side of the hammer body 21. The hammer handle 11 is sleeved inside the mounting groove 22. The fixing groove 23 is provided on one side of the hammer body 21. A gasket is provided on one side of the inner side of the fixing groove 23 to buffer the sleeve 31 and improve the installation stability. A through hole 24 communicating with the mounting groove 22 is provided on one side of the fixing groove 23.

[0030] The buffer head assembly 3 includes a sleeve 31, a rod 32, a hammer head 33, a piston 34, a spring 35, and an air hole 36. The sleeve 31 is threaded to the inside of the fixing groove 23. The inside of the fixing groove 23 is provided with an internal thread, and the outside of the sleeve 31 is provided with an external thread that matches the internal thread, which facilitates assembly and connection. One side of the sleeve 31 is provided with a rod 32 that mates with the insertion hole 14, and the other side of the sleeve 31 is fitted with a hammer head 33. The hammer handle 11, the hammer body 21, and the hammer head 33 are all made of aluminum alloy. Aluminum alloy has low density and light weight, while also having a certain strength and corrosion resistance. One side of the hammer head 33 is provided with a piston 34 that matches the sleeve 31, and one side of the piston 34 is provided with a spring 35. An air hole 36 is opened on one side of the inside of the sleeve 31 to buffer the vibration generated during hammering.

[0031] Example:

[0032] The hammer assembly 2 has a hexagonal nut slot 4 on the side away from the fixing slot 23. The hollow design of the hexagonal nut slot 4 not only allows for the assembly and disassembly of the hexagonal nut using a hammer, but also reduces the amount of material used without affecting its functionality and strength, thereby achieving the goal of lightweighting.

[0033] Working principle: When assembling this hammer, first insert the hammer handle 11 into the mounting groove 22, and then connect the sleeve 31 to the internal thread on the inner side of the fixing groove 23 through its external thread. At this time, the insertion rod 32 can pass through the through hole 24 and be inserted into the insertion hole 14 to fix the hammer handle 11. After fixing, the assembly of the hammer is completed.

[0034] When using the hammer, the user can hold the handle and strike the object with the hammer head 33. When striking, the impact generated by the strike can drive the hammer head 33 to push the piston 34 to one side. At this time, the piston 34 can push the spring 35 to compress and buffer the impact on the hammer head 33. At the same time, it can drive the airflow in the sleeve 31 to be discharged from the air hole 36. Since the diameter of the air hole 36 is small, the airflow is obstructed, which can slow down the movement speed of the hammer head 33 and achieve a damping effect. This can absorb the vibration when the hammer strikes and improve the anti-vibration performance of the hammer.

[0035] Meanwhile, the buffer pad 13 provided on the inner side of the hammer handle 11 can compress the buffer pad 13 to buffer the vibration transmitted to the handle when the hammer handle 11 is subjected to hammering vibration, thereby improving the anti-vibration effect of the hammer.
