Description

Technical Field

[0001] This utility model relates to the field of composite cutting tool technology for CNC machine tools, specifically a composite cutting tool for CNC machine tools. Background Technology

[0002] CNC machine tools are automated machining devices that utilize a computer numerical control system. They are widely used in metalworking, woodworking, and other material processing. They can process complex parts according to preset program instructions, featuring high precision, high efficiency, and high flexibility. CNC machine tools can perform various machining operations such as turning, milling, and drilling, and can quickly switch between different machining programs to adapt to diverse production needs. Composite cutting tools are high-efficiency tools that integrate multiple cutting functions and are widely used in the machining and manufacturing industries. They typically combine turning, milling, and drilling functions, enabling multiple machining operations to be completed in a single setup.

[0003] Existing composite cutting tools for CNC machine tools typically involve directly inserting the tool holder into the end of the transmission rod during installation, and then manually sliding the tool holder to adjust the tool position. This sliding adjustment makes it difficult to accurately control the position, which can easily lead to low tool adjustment precision and consequently affect the processing of materials. Therefore, we propose a composite cutting tool for CNC machine tools. Utility Model Content

[0004] The purpose of this invention is to provide a composite cutting tool for CNC machine tools to solve the problem mentioned in the background art that it is not convenient to accurately control the position of the cutting tool during adjustment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite cutting tool for CNC machine tools, comprising a transmission rod, a sliding opening on the side wall of the transmission rod, a tool holder embedded in the side wall of the transmission rod, a tool head fixedly connected to the rear side of the tool holder, a locking groove on the outer wall of the tool holder, a fixing member fixedly connected to the outer circumference of the transmission rod, an adjusting screw penetrating through the side wall of the fixing member, a turning wheel provided inside the fixing member, a locking member cooperating with the adjusting screw on the side wall of the sliding opening, a limiting post cooperating with the adjusting screw fixedly connected inside the locking member, a locking block fixedly connected to the bottom of the locking member, and a fastening knob provided at the rear side of the adjusting screw.

[0006] Preferably, the top of the transmission rod has an embedded tube extending through it, and the input end of the embedded tube is fixedly connected to a connector.

[0007] Preferably, the output end of the embedded tube is fixedly connected to an internal tube, one end of the internal tube is fixedly connected to an exhaust head, and the other end is fixedly connected to an exhaust pipe.

[0008] Preferably, the outer circumferential wall of the exhaust pipe is provided with an air hole, and the inside of the transmission rod is provided with a through hole that matches the air hole.

[0009] Preferably, the fastening knob is fitted to the side wall of the locking member, and the side wall of the locking member has a cavity that fits into the limiting post.

[0010] Preferably, the outer wall of the transmission rod is provided with a locking bolt, and the exhaust head is fitted to the rear side of the transmission rod.

[0011] Preferably, the transmission rod has a sliding hole inside that matches the tool holder, and the tool holder has a cuboid structure.

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

[0013] 1. This utility model involves inserting the tool bar into the transmission rod, pressing the locking member to displace it further into the transmission rod, and then engaging the tool bar with a locking block in the locking groove. Tightening the locking knob connects the tool bar to the adjusting screw. Manually turning the dial allows the adjusting screw to make a slight displacement, which, through the locking member, moves the tool bar within the transmission rod, thus achieving precise adjustment of the composite tool's tip. This results in a simple structure, convenient operation, and easy maintenance.

[0014] 2. After the cutter bar is used, the connector can be connected to an external air pump. After the air pump supplies air into the embedded tube, the airflow can be discharged from the exhaust head through the internal tube. The airflow can be used to clean the cutter head. At the same time, the airflow can be discharged from the air hole of the exhaust pipe into the interior of the transmission rod, and then the airflow can be discharged from the sliding port. This realizes the air blowing cleaning of the interior of the transmission rod and the structure near the sliding port, solving the trouble of inconvenient cleaning of the interior of the transmission rod and the structure near the sliding port, and saving manpower.

Detailed Implementation

[0020] 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.

[0021] Example

[0022] Please see Figures 1-4 The figure shows a composite cutting tool for a CNC machine tool, including a transmission rod 100, a sliding opening 101 on the side wall of the transmission rod 100, a tool holder 110 embedded in the side wall of the transmission rod 100, a tool head 111 tightly welded to the rear side of the tool holder 110, a snap-fit ​​groove 112 on the outer wall of the tool holder 110 that mates with a snap-fit ​​block 132, a fixing member 120 tightly welded to the outer circumference of the transmission rod 100, an adjusting screw 122 penetrating through the side wall of the fixing member 120, and a turning wheel 121 rotatably connected inside the fixing member 120. The outer surface of 121 has anti-slip texture. The side wall of the sliding port 101 is provided with a locking member 130 that cooperates with the adjusting screw 122. The length of the sliding port 101 extends to the rear side of the fixing member 120, which can ensure that the locking member 130 drives the tool bar 110 to move. The locking member 130 has a limiting post 131 that cooperates with the adjusting screw 122 tightly welded inside. The bottom of the locking member 130 has a snap block 132 tightly welded. The rear side of the adjusting screw 122 is provided with a fastening knob 123, which is a bolt that can be directly turned.

[0023] Specifically, the top of the transmission rod 100 is penetrated by an embedded tube 140, and the input end of the embedded tube 140 is tightly welded with a connector 141. The connector 141 is connected to a commercially available external air pump through a common rubber pipe.

[0024] Furthermore, an internal tube 142 is fixedly connected to the output end of the embedded tube 140. An exhaust head 143 is fixedly connected to one end of the internal tube 142. The exhaust head 143 is made of soft plastic tube and has a stainless steel strip embedded in its outer wall. The bendable exhaust head 143 allows the exhaust direction of the exhaust head 143 to face the cutting head 111 of the tool. An exhaust pipe 150 is fixedly connected to the other end.

[0025] Furthermore, the exhaust pipe 150 has an air hole 151 on its outer circumference, and the transmission rod 100 has a through hole 152 that matches the air hole 151.

[0026] Furthermore, the fastening knob 123 is fitted to the side wall of the locking member 130, and the side wall of the locking member 130 has a cavity that fits into the limiting post 131. A spring is fitted on the outside of the limiting post 131, and the limiting post 131 can be limited when the locking member 130 slides.

[0027] It is worth noting that the outer wall of the transmission rod 100 is provided with multiple locking bolts that cooperate with the tool bar 110. When the adjustment of the tool bar 110 is completed, the locking bolts can be tightened to lock and fix the tool bar 110. The exhaust head 143 is fitted to the rear side of the transmission rod 100.

[0028] It is worth noting that the transmission rod 100 has a sliding hole inside that matches the tool holder 110, and the tool holder 110 has a cuboid structure.

[0029] Working principle: After inserting the tool holder 110 into the transmission rod 100, pressing the locking member 130 causes it to move inward into the transmission rod 100. The locking member 130 then engages with the locking slot 112 via the locking block 132, thus locking the tool holder 110 in place. Tightening the locking knob 123 connects the tool holder 110 to the adjusting screw 122. Manually turning the dial wheel 121 causes a slight displacement of the adjusting screw 122, which, through the locking member 130, moves the tool holder 110 within the transmission rod 100. This achieves a slight adjustment of the position of the composite tool's cutting head 111, allowing for precise adjustment of the composite tool's position. It is more precise and time-saving, with a simple structure, convenient operation, and easy maintenance. After the tool holder 110 is used, the connector 141 can be connected to an external air pump. After the air pump supplies air into the embedded tube 140, the airflow can be discharged from the exhaust head 143 through the internal tube 142. The airflow can be used to clean the tool head 111. At the same time, the airflow can be discharged from the air hole 151 of the exhaust pipe 150 into the interior of the transmission rod 100, and then the airflow can be discharged from the sliding port 101. This realizes the air blowing cleaning of the interior of the transmission rod 100 and the structure near the sliding port 101, solving the trouble of inconvenient cleaning of the interior of the transmission rod 100 and the structure near the sliding port 101, and saving manpower.
