Description

Technical Field

[0001] The invention relates to the technical field of reamer, in particular to a quick-change adjustable welding reamer. Background Art

[0002] Welding a reamer generally refers to the process of repairing, reinforcing or customizing a reamer. A reamer is a mechanical part used for connection and motion control, commonly found in doors, windows, furniture and mechanical equipment, used to connect two parts and allow them to rotate relative to each other. Welding may be required when a reamer is worn, damaged during use or requires a specific shape or size.

[0003] Quick-change adjustable welding reamer Because the reamer can be quickly replaced or adjusted, workers can adapt to different workpiece requirements more quickly, saving adjustment time and improving production efficiency. The quick-change design makes operation easier, reduces the skills and time costs required by the operator, and also reduces the risk of misoperation.

[0004] However, most welding reamers do not have a quick-disassembly structure during use. Screws are usually used to fix the reamers inside the tool holder for use. During the cutting process, the screws may rust or bend due to factors such as coolant or cooling water, making it difficult to disassemble and replace them. Summary of the invention

[0013] Preferably, the outer wall of the inner support clamp is slidably connected to a knife body, the outer wall of the knife body is provided with a welding groove, the outer wall of the knife body is provided with a blade, and the outer wall of the blade is fixedly connected to the inner wall of the welding groove.

[0014] Preferably, an adjusting ring is fixedly connected to the inner wall of the cutter body, a bolt is threadedly connected to the inner wall of the adjusting ring, and an outer wall of the bolt is threadedly connected to the inner wall of the fixing plate.

[0015] Preferably, an oil hole is provided on the inner wall of the bolt, and a mounting ring is opened on the inner wall of the bolt.

[0017] Working principle: when the reamer is needed, the collar is inserted into the inner wall of the fixed ring through the tool handle, the gear is driven to rotate on the inner wall of the fixed ring through the motor, the gear drives the gear ring to rotate on the inner wall of the fixed ring through the gear, the gear drives the gear rack to slide on the inner wall of the fixed ring through the gear ring, and the gear ring drives other gears inside the fixed ring to rotate during movement. The fixed ring can achieve synchronization, thereby avoiding the problem of gaps in the middle caused by the offset and asynchronism of multiple fixed plug plates during movement. During use, the fixed plug plate is driven by the rack to insert into the inner wall of the fixed groove to quickly fix the tool handle, and the shape of the fixed groove is the same as that of the fixed plug plate, which is convenient for the fixed plug plate to be inserted and fixed during use. The tool body is sleeved on the outer wall of the tool handle, the electric push rod drives the support rod to move upward or downward, and the connecting sleeve drives the first connecting plate to drive the inner supporting card plate to open outward, which can achieve the effect of quickly supporting and fixing the tool body, and the position where the inner supporting card plate is opened is provided with a card groove the same as the inner supporting card plate on the inner wall of the tool body during use, which can avoid the problem of slipping during high-speed rotation for cutting, thereby achieving the effect of quick installation and fixing, and the multi-stage installation method can quickly disassemble the tool body during cutting, thereby achieving a variety of drilling effects, and during use, the cooling oil is transported forward to the inside of the tool handle through the inside of the tool holder, and the oil is transported to the fixed plate and the inner wall through the cooling oil pipe during use. The middle part of the adjusting ring is screwed into the adjusting ring and the fixing plate during installation to further fix the cutter body, and also has the effect of adjusting the tightness of the cutter body. It can be adjusted according to the process used during use. During use, the cooling oil is transported to the inside of the spray shell through the oil hole, and is temporarily stored in the spray shell and sprayed out through the cooling nozzle. During use, when the cutter body rotates at high speed for cutting, it can not only cool the blade, but also has the effect of spraying coolant on the cut object to cool it down to prevent deformation caused by excessive temperature. In the process of high-speed rotation, the coolant is sprayed in a spiral state, which can flush out the residual cutting debris inside during drilling. The effect of avoiding wear and damage to the blade caused by debris can be avoided. During use, when the blade is sleeved on the outer wall of the limiting ring and the positioning rod, the positioning rod and the limiting ring further fix the blade. During the installation process, the positioning rod can position and install the blade. Not only can the slot where the inner support clamp is opened and fixed during installation be further determined, but it can also prevent shaking after being sleeved, so that it can be more accurate after installation. The welding groove outside the blade body can position the blade when welding the blade. While ensuring the welding position during welding, it also prevents the blade from shaking and falling off when placed on the top of the blade body, which may cause the blade to fall off during welding and reduce the difficulty of welding.

[0018] The present invention provides a quick-change adjustable welding reamer. It has the following beneficial effects:

[0019] 1. The present invention drives the sleeve ring to be inserted into the inner wall of the fixed ring through the tool handle, drives the gear to drive the gear ring to move through the motor, drives other gears to rotate through the gear ring during use, drives the rack to slide on the inner wall of the fixed ring through the gear, and drives the fixed plug plate to slide into the inner wall of the fixed groove through the rack. During use, the tool handle can be quickly installed and disassembled, and the tool handle or other cutting tools can be quickly replaced according to production conditions.

[0020] 2. The present invention drives the connecting sleeve to move up and down through the electric push rod, and drives the first connecting plate through the connecting sleeve to drive the inner supporting card to open on the inner wall of the knife body, so that the inner supporting card can be clamped on the inner wall of the knife body to quickly fix the knife body. The inner supporting card can be limited by the second connecting plate to achieve the effect of positioning and centering, and can maintain better stability when supporting the knife body. During use, the knife body can be quickly replaced through the inner supporting card. During use, the knife body can be replaced according to the degree of wear of the knife body, or when welding the blade, the blade can be conveniently welded by removing the knife body.

[0021] 3. The present invention delivers cooling oil to the cavity of the tool handle through the tool holder, intercepts the cooling oil through the connecting seat and delivers the cooling oil to the cavity between the fixed plate and the adjusting ring through the cooling oil pipe, and delivers the cooling oil to the inside of the spray shell through the oil hole set by the bolt. During the cutting process, the cooling oil is used to cool the blade to prevent deformation and extend the service life. When the cooling oil is sprayed from the cooling nozzle by the tool holder driving the rotation, the cut chips can be flushed out of the drill hole during the cutting process, thereby avoiding the additional wear of the blade by the chips during use.
