Description

Technical Field

[0001] The invention relates to the technical field of rare earth oxide production, and in particular to a portable pneumatic breaker with adjustable hammering force. Background Art

[0002] Rare earths are precious metals. Rare earth metals are often refined at high temperatures. When they come out of the furnace, they are still in liquid form. Currently, liquid rare earths are taken out of the rare earth electrolytic furnace by means of robotic gripping or siphoning. Regardless of whether a robotic arm or a siphon is used, the liquid rare earths are often easily attached to the arm of the robotic arm or the siphon pipe. If used for a long time, a thick metal adhesive layer will form on the robotic arm, and the siphon pipe will be blocked. Rare earths are precious metals, and the metal attached to the pipe also generates a lot of energy waste.

[0003] If manual hammering is used, the environment of rare earth molten salt electrolysis is often more complex, harsh, and dangerous. In addition, manual hammering often has problems in controlling the force of the blow, which often leads to fractures in the welds and damages to the robotic arm or siphon pipe, seriously damaging its service life. Manual hammering is also very dangerous. Summary of the invention

DETAILED DESCRIPTION

[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] See also Figure 1 The present invention provides a portable pneumatic breaker with adjustable hammering force, comprising a left clamp 1, a right clamp 2, an impact cylinder 3, a pneumatic valve switch device 4 and a breaker hammer 5, wherein the left clamp 1 and the right clamp 2 are connected by a pin, the impact cylinder 3 is arranged at the clamp head position of the left clamp 1, the breaker hammer 5 is movably connected with the impact cylinder 3 and is located at one side of the output end of the impact cylinder 3, the pneumatic valve switch device 4 is installed in the middle of the clamp handle of the left clamp 1, the clamp handle is a hollow round steel, and the air pipe 6 is connected to the air inlet of the impact cylinder 3 through the end of the hollow round steel;

[0021] The clamp head of the left clamp 1 is provided with an upper baffle 11 and a lower baffle 12, and the upper baffle 11 and the lower baffle 12 are arranged relatively parallel, and the upper baffle 11 and the lower baffle 12 are fixedly connected through the clamp body on the right side, and a circular through hole 13 is opened in the middle of the clamp body on the right side, and the impact cylinder 3 is arranged between the upper baffle 11 and the lower baffle 12, and one end of the breaker 5 passes through the circular through hole 13 and is movably connected with the impact cylinder 3.

[0022] The left clamp 1 is further provided with a clamping baffle 14, and the clamping baffle 14 is fixedly connected to the upper baffle 11 and the lower baffle 12 respectively by bolts.

[0023] A top bolt 21 is disposed on the top of the clamp head of the right clamp 2 , one end of the top bolt 21 is fixed to the right clamp 2 by threads, and the other end of the top bolt 21 abuts against the upper baffle 11 .

[0024] The right clamp 2 is provided with a right baffle plate 22 , which is arranged opposite to the breaker hammer 5 , and a side of the right baffle plate 22 facing the breaker hammer 5 is arranged in a sawtooth shape.

[0025] The portable pneumatic breaker with adjustable hammering force further comprises a shoulder strap 7, and two ends of the shoulder strap 7 are fixedly connected to the left clamp 1 and the right clamp 2 respectively.

[0026] The driving pressure of the impact cylinder 3 is not less than 3KG.

[0027] In this specific embodiment, the inflation pipe 6 in the hollow round steel is connected to the air inlet of the impact cylinder 3 through the end of the round steel. Providing a pressure greater than 3kg is sufficient to drive the impact cylinder 3. When the external air pump is turned on, it does not need to be turned off throughout the process. The pneumatic valve switch device 4 is controlled to determine the on-off of the air source, and the hammering and stopping actions of the breaker are achieved by controlling the on-off of the air source.

[0028] Specifically, the impact cylinder 3 is installed at the left clamp 1, and the breaker 5 is installed on the impact cylinder 3 at the circular through hole 13 of the left clamp 1. The left clamp 1 fixes the impact cylinder 3 through the clamping baffle 14. The upper baffle 11 and the lower baffle 12 are respectively connected and fixed to the clamping baffle 14 by bolts. The middle of the jaws of the right clamp 2 is the right baffle 22, which is serrated. The purpose of the serrated shape of the right baffle 22 is to reduce the contact area and prevent metal from adhering to the baffle during repeated hammering. The purpose of the top bolt 21 at the top of the right clamp 2 is to play a clamping role. The mechanical arm that needs to be attached with rare earth metals and electrolytes is inserted. At this time, the top bolt 21 can support the upper baffle 11, which plays a role in fixing the position of the mechanical arm that needs to be broken. After the breaker 5 is in the working position, the impact cylinder 3 is inflated through the inflation pipe 6 at the right end, and the impact cylinder 3 controls the breaker 5 to produce reciprocating motion.

[0029] During crushing, the flow rate of the air inlet can be adjusted to control the hammering force of the breaker 5 according to the actual adhesion of the attached objects, effectively avoiding the uneven force of the manipulator due to manual knocking, which leads to the breakage of the weld interface at the connection part of the manipulator arm. The present invention mainly causes the attached objects to fall off by clamping vibration, rather than the direct impact of the hammer used by workers.

[0030] Furthermore, the portable pneumatic breaker with adjustable hammering force is also provided with a shoulder strap 7. When operating, the worker carries the pneumatic breaker on his back through the shoulder strap 7, which is convenient for operation and saves the worker's effort. When the worker carries it on his back, it is more convenient to control. The role of the shoulder strap 7 greatly improves the worker's safety protection ability and control ability during operation. Secondly, the shoulder strap 7 can also make the equipment easy to carry.

[0031] In summary, the present invention has the following benefits:

[0032] 1. The attachments on the pipe are broken by inserting, which can be applied to various complex scenes such as manipulators and siphon pipes, and has strong adaptability;

[0033] 2. It can be driven by a pressure of more than 3kg, the air pressure used is small and the structure is simple;

[0034] 3. It can be carried on the body with a shoulder strap, which is convenient for use during work;

[0035] 4. The duration and strength of the impact can be manually controlled at will, which can protect the robotic arm or siphon pipe with high efficiency;

[0036] 5. The transition from manual to automatic has been completed, greatly enhancing the safety of workers in their operations.

[0037] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
