Description
Technical Field
[0001] This utility model relates to the field of tool holder technology, specifically a CNC vertical lathe tool holder for wind power flanges. Background Technology
[0002] The CNC vertical lathe tool holder is a component used on the spindle of a CNC lathe or a conventional lathe. It uses the elastic principle of a spring collet to clamp workpieces with small diameters and high precision.
[0003] Currently, vertical lathe tool holders mainly consist of a straight shank, a pressure cap, and a spring clip, and are fixed to the spindle by a pull rod or pull stud. The rotating spindle drives the tool holder to descend at a constant speed, allowing drilling operations to be performed on the wind turbine flange. This type of tool holder releases coolant from the inside out, but this coolant release method can only cool the inside of large flange holes. Since the tool holder needs to descend at a constant speed along the upper surface of the flange, it is difficult to effectively cool the upper surface of the flange and the area around the hole. In severe cases, this can cause deformation of the upper surface of the flange, the hole, and the surrounding area.
[0004] In view of this, a CNC vertical lathe tool holder for wind turbine flanges was designed to solve the above problems. Utility Model Content
[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0006] Therefore, the technical solution adopted by this utility model is as follows: A CNC vertical lathe tool holder for wind turbine flanges includes a tool head adapter mechanism and a turning mechanism mounted on the tool head adapter mechanism. The tool head adapter mechanism includes a cap clamp with a groove at its bottom. Four evenly distributed flow guides are arranged in the groove. Four symmetrically distributed pressure boosters are fixedly installed inside the four flow guides. A spray net is fixedly installed at the bottom of each pressure booster. A flow guide cavity is formed inside each flow guide and is connected to the pressure booster. The turning mechanism includes a tool movably mounted inside the four flow guides. A guide tube is formed inside the tool. A turning head is fixedly installed at the bottom end of the guide tube. A tapered cavity is formed inside the turning head. Multiple cooling holes are formed on the outer wall of the turning head. Four flow diversion slots are formed on the top section of the tool and are connected to the flow guide cavity.
[0007] In a preferred embodiment, the present invention can be further configured as follows: four screw holes are provided on the bottom of the inner side of the cap clip; two buckle plates are movably installed on the bottom of the inner side of the cap clip; two locking bolts are inserted into the grooves on the top of the buckle plates; washers are provided on the outside of the locking bolts; and the threaded section of the locking bolts is adapted to be installed in the screw holes.
[0008] In a preferred embodiment, the present invention can be further configured such that: a plug is fixedly installed on the top of the air guide, and a slot adapted to the plug is provided at the bottom of the cap clip.
[0009] In a preferred embodiment, the present invention can be further configured such that: a limiting groove is formed on the inner wall of the flow guide, two tension springs symmetrically distributed are fixedly installed on the inner side of the limiting groove, and plugs are fixedly installed on the outer ends of the two tension springs.
[0010] In a preferred embodiment, the present invention can be further configured such that: an annular groove is provided on the rod segment through which the cutter penetrates into the cap clamp, and two buckles are engaged in the annular groove; and an injection tube is inserted into the top of the cutter.
[0011] In a preferred embodiment, the present invention can be further configured such that: a vertical hole is provided in the middle of the cutting tool, a guide tube is installed inside the vertical hole, and the guide tube is fixedly installed at the top of the turning head.
[0012] In a preferred embodiment, the present invention can be further configured such that the outer wall of the turning head has multiple evenly distributed oblique grooves.
[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. This utility model sets the existing integral tool holder structure as a spliced tool head adapter mechanism and a turning mechanism. When the turning mechanism is pressed and squeezed into the interior of the wind power flange, the mainstream coolant will spray directly into the flange hole through the internal passage of the turning mechanism. The diverted coolant will cool the flange upper surface holes and its surrounding parts through the top pressure shroud and spray net. While improving the structural problems during flange drilling, the progressive liquid flow can actively discharge the turning waste.
[0014] 2. By adding a turning head to the bottom of the cutting tool, after the cutting tool and turning head have been used for a long time and have worn out, only the individual cutting tool and turning head need to be replaced. The subsequent assembled cutting tool and turning head do not need to be recalibrated with the spindle and can be put into use quickly. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0018] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0019] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a CNC vertical lathe tool holder for wind power flanges.
[0020] Example 1: Combination Figures 1 to 5 As shown, the present invention provides a CNC vertical lathe tool holder for wind turbine flanges, including a tool head conversion mechanism 100 and a turning mechanism 200 mounted on the tool head conversion mechanism 100. The tool head conversion mechanism 100 is fixed to the spindle and provides a conversion platform for the turning mechanism 200. The turning mechanism 200 is used to drill holes in the wind turbine flange.
[0021] The cutter head adapter mechanism 100 includes a cap clip 110. The bottom of the cap clip 110 has a groove, and four evenly distributed flow guides 140 are arranged in the groove. Four symmetrically distributed pressure boosters 150 are fixedly installed in the four flow guides 140. A spray net 1501 is fixedly installed at the bottom of the pressure booster 150. A flow guide cavity 1402 is opened inside the flow guide 140 and is connected to the pressure booster 150. Four screw holes are opened on the bottom inner side of the cap clip 110. Two buckle plates 120 are movably installed on the bottom inner side of the cap clip 110. Two locking bolts 130 are inserted into the groove at the top of the buckle plate 120. Washers 1301 are provided on the outside of the locking bolts 130, and the threaded section of the locking bolts 130 is adapted to be installed in the screw hole. The turning mechanism 200 includes a cutting tool 210 movably installed in four guide shrouds 140. The cutting tool 210 has a guide tube 230 inside. A turning head 240 is fixedly installed at the bottom end of the guide tube 230. The turning head 240 has a tapered cavity 2401 inside. The outer wall of the turning head 240 has multiple cooling holes 2402. The top section of the cutting tool 210 has four flow-diverting slots 2102, and the flow-diverting slots 2102 are connected to the guide cavity 1402.
[0022] The assembled cap clamp 110 is fixed to the bottom section of the spindle using a tie rod. As the machine tool spindle rotates and drives the tool head transfer mechanism 100 and the turning mechanism 200, the turning head 240 and the cutting tool 210 will drill downwards along the upper surface of the wind turbine flange. As the spindle continues to descend, the turning head 240 will squeeze into the interior of the flange, while the cutting tool 210 will precisely drill into the interior of the flange. Meanwhile, as the coolant is injected into the vertical hole 2101 through the injection pipe 220, the instantaneously dropping coolant will be transferred from the guide pipe 230 to the conical cavity 2401, and finally sprayed downwards from multiple cooling holes 2402. The coolant sprayed from the multiple cooling holes 2402 will cool the holes inside the flange. As the hydraulic pressure increases, the coolant will be output from the four diversion slots 2102 and push the four plugs 1404 outwards. The coolant will be transferred to the guide cavity 1402. Finally, the coolant that is diverted to the inner cavity of the pressure shroud 150 will be sprayed from the spray net 1501, and the sprayed coolant will cool the upper surface of the wind power flange. At the same time, the thrust generated at the confluence of the two water streams will quickly discharge the machining waste.
[0023] Example 2: Combination Figure 2 and Figure 4 As shown, based on Embodiment 1, a plug 1401 is fixedly installed on the top of the flow guide 140, and a slot 1101 adapted to the plug 1401 is provided at the bottom of the cap clip 110. The inner wall of the flow guide 140 has a limiting groove 1403. Two tension springs 1405 are fixedly installed on the inner side of the limiting groove 1403, and plugs 1404 are fixedly installed on the outer ends of the two tension springs 1405.
[0024] Preferably, the outer wall of the flow guide shroud 140 is provided with a fan-shaped slot, and a sealing gasket is provided in the gap between two adjacent flow guide shrouds 140. As the coolant is output from the diversion slot 2102, the coolant will push open the plug 1404. At this time, the diversion slot 2102 and the flow guide cavity 1402 will be in a connected state. As the coolant is continuously input into the flow guide cavity 1402, the coolant under sufficient pressure can be transferred to the inner cavity of the pressure booster shroud 150 and finally sprayed directly downward from the spray net 1501, thereby improving the stability of the upper surface structure of the wind power flange.
[0025] Example 3: Combination Figures 2 to 4 As shown, in the above embodiment, the rod segment of the cutter 210 that penetrates into the cap clip 110 has an annular groove, and two buckles 120 are snapped into the annular groove. An injection tube 220 is inserted into the top of the cutter 210. The cutting tool 210 has a vertical hole 2101 in the middle, and a guide tube 230 is installed inside the vertical hole 2101. The guide tube 230 is fixedly installed on the top of the turning head 240. The outer wall of the turning head 240 has multiple evenly distributed inclined grooves 2403.
[0026] Preferably, the turning head 240 has an overall conical structure, and the guide tube 230 is welded to the turning head 240. The turning head 240 is also welded to the bottom of the tool 210. When the machine tool spindle descends, the turning head 240 will pre-drill holes on the upper surface of the wind power flange. The subsequently rotating and descending tool 210 will further drill holes in the pre-drilled areas. The coolant sprayed from the cooling hole 2402 will squeeze the waste debris in the hole upwards, and the coolant sprayed downwards from the multiple spray nets 1501 will discharge the squeezed waste debris outwards.
[0027] The working principle and usage process of this utility model are as follows: First, four pressure shrouds 150 and four flow guide shrouds 140 are welded together. Then, the top of the four flow guide shrouds 140 is inserted into the hole at the bottom of the cap clip 110 until the insert block 1401 is properly inserted into the inside of the slot 1101. Then, the rod section at the top of the cutter 210 is inserted into the inside of the four flow guide shrouds 140 until the rod section at the top of the cutter 210 penetrates to the inside of the cap clip 110. Then, two buckle plates 120 are snapped into the annular groove of the rod section at the top of the cutter 210, and the two buckle plates 120 are fixedly installed at the bottom of the inside of the cap clip 110 using four washers 1301 and four locking bolts 130. Then, the cap clip 110 is fixed to the machine tool spindle using the pull rod. At this time, the liquid injection pipe 220 installed at the top of the tool 210 will connect with the water supply pipe of the spindle inside the machine tool. As the machine tool spindle rotates and drives the tool head adapter mechanism 100 and the turning mechanism 200 to rotate in linkage, when the spindle descends, the bottom-positioned turning head 240 is pressed into the upper surface of the wind power flange rough material. As the spindle continues to descend, the turning head 240 and the cutting tool 210 will quickly drill holes in the wind power flange. Meanwhile, the coolant enters the tapered cavity 2401 through the turning head 240 and the guide tube 230. Finally, the coolant will be sprayed into the holes of the wind power flange from multiple cooling holes 2402. When the turning head 240 is completely inside the wind power flange, the excessive hydraulic pressure will cause the four plugs 1404 to extend into the guide cavity 1402. The diversion slot 2102 and the guide cavity 1402 are in a connected state, and some coolant will be sprayed vertically downwards through the four pressure shrouds 150 and the spray net 1501 to ensure effective temperature control during drilling of the upper surface of the wind power flange.
