Description

Technical Field

[0001] This utility model relates to the field of hole machining technology, specifically a composite tool holder for hole machining. Background Technology

[0002] Hole machining is a crucial process in manufacturing, referring to the drilling or machining of holes in materials. Hole machining can utilize various tools and techniques, with the specific method depending on the type and size of the hole and the properties of the material being machined. Composite tool holders used for hole machining combine multiple materials and technologies to enhance cutting performance and wear resistance. These tool holders are typically made of high-strength cemented carbide or ceramic materials and may be coated with high-performance coatings to improve wear resistance and oxidation resistance.

[0003] Existing composite tool holders for hole machining typically have an outer sleeve for supporting the tool body. The power input end of the tool body is fixed to a drive motor to perform drilling operations. The outer sleeve is usually fixed to the support frame of the drilling equipment using multiple bolts to support the tool holder. However, the use of multiple bolts for fastening means that the tool holder needs to be disassembled and replaced, requiring repeated tightening with tools. This makes the disassembly and replacement of the tool holder cumbersome, inconvenient, time-consuming, and labor-intensive. Therefore, we propose a composite tool holder for hole machining. Utility Model Content

[0004] The purpose of this invention is to provide a composite tool holder for hole machining, so as to solve the problem of the cumbersome and inconvenient disassembly operation of the tool holder mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite tool holder for hole machining, comprising a mounting base, an outer casing fixedly connected to the side wall of the mounting base, a central block fixedly connected inside the outer casing, a connecting block fitted to the side wall of the mounting base, a snap-fit ​​block fixedly connected to the left side wall of the connecting block, a sleeve fixedly connected to the right side wall of the connecting block, a rod body disposed inside the sleeve, a tool head fixedly connected to the top of the rod body, a locking element disposed at the top of the outer casing, and a fixing ring disposed on the front side wall of the locking element.

[0006] Preferably, the outer wall of the fixing ring is provided with external threads, and a cover is fitted over the outside of the fixing ring.

[0007] Preferably, a rubber ring is fixed to the side wall of the cover, and a moisture-absorbing cotton sheet is provided inside the cover.

[0008] Preferably, the absorbent cotton sheet has a short spring on its sidewall, and the short spring has a top plate on its sidewall.

[0009] Preferably, a locking knob is provided inside the fixing ring, and the locking knob is engaged with the outer wall of the locking member.

[0010] Preferably, the side wall of the snap-fit ​​block is fixedly provided with a protrusion, and the side wall of the middle block is provided with an anti-slip strip that cooperates with the snap-fit ​​block.

[0011] Preferably, a stop bar is fixedly connected to the side wall of the locking member, and the stop bar cooperates with the side wall of the connecting block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model provides a connecting block with a snap-fit ​​block on the sleeve side wall outside the tool holder, and an outer casing and a middle block on the tool holder mounting base. The connecting block can be slidably connected with the mounting base, and the locking piece can be sleeved on the top of the mounting base. Then, the locking knob is turned to lock it. At this time, the snap-fit ​​block is pressed against the side wall of the middle block, and the locking piece covers the top of the outer casing of the mounting base, thereby realizing the quick connection of the tool holder, eliminating the trouble of using tools to tighten bolts, facilitating the quick disassembly and replacement of the tool holder, and increasing the convenience of using the composite tool holder.

[0014] 2. After the locking knob is locked, the cover is turned to cover the outside of the fixing ring. At this time, the short spring of the cover and the top piece press against the side wall of the locking knob. The cover can be used to seal the fixing ring, reducing the amount of external moisture entering the inside of the fixing ring and causing corrosion of the locking knob. At the same time, it can reduce the risk of the locking knob coming out of the fixing ring. Attached Figure Description

A connecting block 110 is fitted to the side wall of the mounting base 100. A snap-fit ​​block 111 is tightly welded to the left side wall of the connecting block 110. A sleeve 120 is tightly welded to the right side wall of the connecting block 110. A rod 121 is rotatably connected inside the sleeve 120. The rod 121 is made of hard alloy, ceramic and coating materials. A drive motor fixed to the support frame is provided at the power input end of the rod 121. A tool head 122 is tightly welded to the top of the rod 121. A locking member 130 is provided at the top of the outer casing 101. A fixing ring 140 is provided on the front side wall of the locking member 130.

[0023] Specifically, the outer wall of the fixing ring 140 is provided with an external thread 141, and a cover 150 is fitted on the outside of the fixing ring 140. The cover 150 is made of stainless steel commonly found on the market.

[0024] Furthermore, the sidewall of the cover 150 is bonded with a rubber ring 151 using common adhesive, and the inside of the cover 150 is provided with a moisture-absorbing cotton sheet 152, which is made of highly absorbent fibers.

[0025] Furthermore, the moisture-absorbing cotton sheet 152 has a short spring 153 on its side wall, and a top plate 154 is provided on the side wall of the short spring 153. The top plate 154 is a stainless steel sheet.

[0026] Furthermore, a locking knob 132 is provided inside the fixing ring 140. The locking knob 132 is made entirely of stainless steel and fits into the outer wall of the locking member 130.

[0027] It is worth noting that the side wall of the snap-fit ​​block 111 is tightly welded with a protrusion 112, and the side wall of the middle block 102 is provided with an anti-slip strip 103 that matches the snap-fit ​​block 111. The side wall of the snap-fit ​​block 111 is provided with an anti-slip texture that matches the anti-slip strip 103. When the locking knob 132 is tightened, the snap-fit ​​block 111 can be pressed tightly against the side wall of the middle block 102.
