Description

Technical Field

[0001] This utility model relates to the field of coolant circulation guide devices for threaded cutting tools, and in particular to a high-precision coolant circulation guide device for threaded cutting tools. Background Technology

[0002] The coolant circulation guide device for threaded cutting tools consists of a support frame, a coolant circulation guide device, a liquid pool, an inlet pipe, a connecting pipe, a rotating device, a fixing ring, a clamping device, a threaded cutting tool body, and a spraying device. It is a high-precision coolant circulation guide device for threaded cutting tools mainly used for machining internal threads and is quite common in existing technologies.

[0003] Existing technologies, such as the utility model patent with publication number CN209256682U, disclose a coolant circulation and filtration system for a tap and thread grinding machine. This patent employs a delivery pump, a spray pipe, a liquid pool, and a waste liquid collection structure, and also includes a filtration device. The tap and thread grinding machine includes a frame and a grinding disc. The spray pipe is fixed relative to the frame with its outlet facing the grinding position of the grinding disc. The liquid pool is located below the frame. The delivery pump pumps the coolant from the liquid pool to the spray pipe through a pipe. The waste liquid collection structure is located on the upper surface of the frame. The filtration device is located between the waste liquid collection structure and the liquid pool and connected by a pipe. When the delivery pump is started, it pumps the coolant from the liquid pool to the spray pipe, which sprays it onto the grinding disc and workpiece of the grinding machine for cooling. Used coolant, mixed with debris, enters the waste liquid collection structure. The filtration device removes large metal debris particles, and the coolant with less impurity flows back to the liquid pool, achieving the effect of coolant recycling.

[0004] The inventors discovered in their daily work that the existing method of connecting the pipe to the inlet pipe involves using multiple bolts, and requiring the use of wrenches and other tools to secure the pipe. This cumbersome method leads to low work efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the existing technology uses multiple bolts to connect the connecting pipe to the liquid inlet pipe, and personnel need to use wrenches and other tools to fix the connecting pipe firmly during the connection and installation process. This connection and installation method is very cumbersome and leads to low work efficiency. Therefore, a high-precision threaded cutting tool coolant circulation guide device is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides a high-precision thread cutting tool coolant circulation guide device, comprising: a support frame, a liquid pool, and a docking structure. A rotating device, a fixing ring, and a clamping device are mounted on the upper surface of the support frame. The thread cutting tool body is installed inside the rotating device. A spraying device is installed inside the fixing ring. The coolant circulation guide device body is mounted on the lower surface of the fixing ring. An inlet pipe is installed inside the liquid pool. A connecting pipe is installed at the end of the inlet pipe away from the liquid pool via the docking structure. The arc surface of the inlet pipe is provided with the docking structure, which includes a positioning... The system comprises a positioning tube and a positioning ring. The positioning tube is fixedly connected to the inlet tube, and the positioning ring is fixedly connected to the connecting tube. Two positioning holes are provided on the inner wall of the positioning ring. Two fixing plates are fixedly connected to the arc surface of the positioning tube. A moving plate is slidably connected to the surface of the fixing plate. A connecting plate is fixedly connected to the upper surface of the fixing plate. A spring is fitted on the surface of the fixing plate. The two ends of the spring are fixedly connected to the moving plate and the connecting plate, respectively. A locking block is fixedly connected to the side of the two moving plates that are close to each other. Two limiting rods are fixedly connected to the side of the positioning tube that is close to the positioning ring. The limiting rods are slidably connected to the positioning holes.

[0007] The effect achieved by the above components is that when personnel need to connect and install the connecting pipe onto the inlet pipe, they can move the connecting pipe to make the two limiting rods slide into the inner wall of the positioning hole until the connecting pipe slides into the interior of the positioning pipe and abuts against the inlet pipe. At this time, the two locking blocks just move to the side of the positioning ring away from the positioning pipe, thereby improving the efficiency of personnel connection and installation.

[0008] Preferably, each of the two movable plates is fixedly connected to a handle on the side away from each other, and the handle is U-shaped.

[0009] The effect achieved by the above components is that the handle makes it easier for personnel to move the movable plate, thereby improving the ease of operation for personnel.

[0010] Preferably, an anti-slip sleeve is fixedly connected to the arc surface of the grip, and the cross-section of the anti-slip sleeve is a hollow circle.

[0011] The effect achieved by the above components is that the anti-slip sleeve can increase the friction between the person's hand and the handle, and can prevent the person from slipping when moving the handle.

[0012] Preferably, a guide block is fixedly connected to the end of the limiting rod away from the positioning tube.

[0013] The effect achieved by the above components is that the guide block can limit the position of the limiting rod, making it convenient for personnel to slide the limiting rod into the inner wall of the positioning hole.

[0014] Preferably, the movable plate is a stainless steel plate.

[0015] The effect achieved by the above components is that the stainless steel plate has high strength and good wear resistance, which can prevent the moving plate from deforming during short-term use.

[0016] Preferably, the arc surface of the clamping device is provided with an auxiliary structure, which includes a connecting plate and a mounting ring. The mounting ring is fixedly connected to the clamping device, the connecting plate is fixedly connected to a fixed ring, and the connecting plate is rotatably connected to the threaded cutting edge body. Two mounting rods are fixedly connected to the side of the mounting ring near the fixed ring. The arc surfaces of the two mounting rods are slidably connected to a moving ring, which is slidably connected to the clamping device. A compression spring is sleeved on the arc surface of the mounting rod, and the two ends of the compression spring are fixedly connected to the moving ring and the mounting ring, respectively.

[0017] The effect achieved by the above components is that when using coolant to cool the threaded cutting edge body and parts, the sprayed coolant can be blocked by the connecting plate and the moving ring, preventing the coolant from splashing outside the fixed ring.

[0018] Preferably, a sealing gasket is fixedly connected to the side of the movable ring away from the mounting ring.

[0019] The effect achieved by the above components is that the sealing gasket can increase the sealing between the moving ring and the fixed ring, and can prevent coolant from flowing out between the moving ring and the fixed ring.

[0030] 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 the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figure 1 This utility model provides a high-precision thread cutting tool coolant circulation guide device, comprising: a support frame 1, a liquid pool 5, and a docking structure 3. A rotating device 8, a fixing ring 9, and a clamping device 10 are installed on the upper surface of the support frame 1. A thread cutting tool body 11 is installed inside the rotating device 8. A spraying device 12 is installed inside the fixing ring 9. A coolant circulation guide device body 2 is installed on the lower surface of the fixing ring 9. An inlet pipe 6 is installed inside the liquid pool 5. A connecting pipe 7 is installed at the end of the inlet pipe 6 away from the liquid pool 5 via the docking structure 3. The arc surface of the inlet pipe 6 is provided with the docking structure 3. The arc surface of the clamping device 10 is provided with an auxiliary structure 4.

[0033] In the embodiments of this utility model, please refer to Figures 2 to 4 The docking structure 3 includes a positioning tube 301 and a positioning ring 302. The positioning tube 301 is fixedly connected to the liquid inlet pipe 6, and the positioning ring 302 is fixedly connected to the connecting pipe 7. Two positioning holes 303 are opened on the inner wall of the positioning ring 302. Two fixing plates 306 are fixedly connected to the arc surface of the positioning tube 301. A moving plate 309 is slidably connected to the surface of the fixing plate 306. A connecting plate 307 is fixedly connected to the upper surface of the fixing plate 306. A spring 308 is sleeved on the surface of the fixing plate 306. The two ends of the spring 308 are fixedly connected to the moving plate 309 and the connecting plate 307 respectively. A locking block 310 is fixedly connected to the side of the two moving plates 309 that are close to each other. Two limiting rods 304 are fixedly connected to the side of the positioning tube 301 that is close to the positioning ring 302. The limiting rods 304 are slidably connected to the positioning holes 303. When personnel need to connect and install the connecting pipe 7 onto the inlet pipe 6, they can move the connecting pipe 7 to slide the two limiting rods 304 into the inner wall of the positioning hole 303 until the connecting pipe 7 slides into the interior of the positioning tube 301 and abuts against the inlet pipe 6. At this time, the two locking blocks 310 move to the side of the positioning ring 302 away from the positioning tube 301, thereby improving the efficiency of the connection and installation. Each of the two moving plates 309 is fixedly connected to a handle 311 on the side away from each other. The handle 311 is U-shaped. The handle 311 facilitates the movement of the moving plates 309 and improves the ease of operation. The arc surface of the handle 311 is fixedly connected to an anti-slip sleeve 312, which has a hollow circular cross-section. The anti-slip sleeve 312 increases the friction between the user's hand and the handle 311, preventing slippage during movement. A guide block 305 is fixedly connected to the end of the limiting rod 304 furthest from the positioning tube 301. The guide block 305 limits the limiting rod 304, allowing it to slide easily into the inner wall of the positioning hole 303. The moving plate 309 is made of stainless steel. Stainless steel has high strength and good wear resistance, preventing deformation of the moving plate 309 during short-term use.

[0034] In the embodiments of this utility model, please refer to Figure 5 and Figure 6The auxiliary structure 4 includes a connecting plate 46 and a mounting ring 41. The mounting ring 41 is fixedly connected to the clamping device 10, the connecting plate 46 is fixedly connected to the fixed ring 9, and the connecting plate 46 is rotatably connected to the thread cutting edge body 11. Two mounting rods 42 are fixedly connected to the side of the mounting ring 41 near the fixed ring 9. A movable ring 44 is slidably connected to the arc surface of the two mounting rods 42. The movable ring 44 is slidably connected to the clamping device 10. A compression spring 43 is sleeved on the arc surface of the mounting rods 42. The two ends of the compression spring 43 are fixedly connected to the movable ring 44 and the mounting ring 41, respectively. This achieves the effect that when using coolant to cool the thread cutting edge body 11 and the parts, the sprayed coolant can be blocked by the connecting plate 46 and the movable ring 44, preventing coolant from splashing outside the fixed ring 9. A sealing gasket 45 is fixedly connected to the side of the movable ring 44 away from the mounting ring 41. The sealing gasket 45 can increase the sealing between the movable ring 44 and the fixed ring 9, preventing coolant from flowing out from between the movable ring 44 and the fixed ring 9.

[0035] The working principle of the high-precision thread cutting tool coolant circulation guide device provided by this utility model is as follows: When a person needs to use the thread cutting tool body 11 to work on a part, the person first fixes the part on the clamping device 10, and then moves the clamping device 10 to bring the part closer to the thread cutting tool body 11, so that the thread cutting tool and the part are simultaneously located inside the fixing ring 9. Then, the person starts the rotating device 8 to make the thread cutting tool body 11 process the part. During the processing, the coolant can be sprayed onto the thread cutting tool body 11 and the part through the spraying device 12. The coolant will then pass through the inside of the fixing ring 9 and enter the cooling system. The liquid circulation guide device body 2 finally undergoes sedimentation treatment inside the liquid pool 5. When the amount of coolant in the liquid pool 5 decreases and new coolant needs to be added, personnel can first move the connecting pipe 7 towards the liquid inlet pipe 6. The connecting pipe 7 drives the positioning ring 302 towards the positioning pipe 301 until the connecting pipe 7 slides into the interior of the positioning pipe 301. During the sliding process of the connecting pipe 7 inside the positioning pipe 301, the guide block 305 and part of it will slide into the inner wall of the positioning hole 303. The guide block 305 can limit the limit rod 304, which can facilitate personnel. Slide the limiting rod 304 into the inner wall of the positioning hole 303 until the positioning ring 302 abuts against the two locking blocks 310. The positioning ring 302 will drive the two locking blocks 310 to move away from each other. The locking blocks 310 will drive the moving plate 309 to move away from the positioning ring 302. The moving plate 309 will drive the handle 311 to move away from the positioning ring 302. The handle 311 facilitates the movement of the moving plate 309, improving the ease of operation. Then, the moving plate 309 will also drive the spring 308 to retract, and the handle 311 will drive the anti-slip sleeve 312 to move away from the positioning ring 302. The movement proceeds in the direction specified in the original text. The anti-slip sleeve 312 increases the friction between the user's hand and the handle 311, preventing slippage during movement. The movement continues until the connecting pipe 7 and the inlet pipe 6 come into contact. At this point, the two locking blocks 310 are just offset from the positioning ring 302. The spring 308 then rebounds, causing the locking blocks 310 to move closer to the positioning ring 302 until the moving plate 309 comes into contact with the positioning ring 302. The moving plate 309 is made of stainless steel, which has high strength and good wear resistance, preventing deformation of the moving plate 309 during short-term use.

[0036] Additionally, when the clamping device 10 is activated to move the part closer to the fixed ring 9, the clamping device 10 will drive the mounting ring 41 to move closer to the fixed ring 9. The mounting ring 41 will drive the two limit rods 304 and the two compression springs 43 to move closer to the fixed ring 9. The two compression springs 43 will drive the moving ring 44 to move closer to the fixed ring 9. The moving ring 44 will drive the sealing gasket 45 to move closer to the fixed ring 9 until the sealing gasket 45 abuts against the fixed ring 9. At this time, the mounting ring 41 will move closer to the moving ring 44. The mounting ring 41 will drive the two compression springs 43 to rewind. The sealing gasket 45 can increase the sealing between the moving ring 44 and the fixed ring 9 and prevent coolant from flowing out between the moving ring 44 and the fixed ring 9.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
