Description

Technical Field

[0001] This utility model belongs to the field of spinneret polishing technology, and in particular relates to a multi-bladed hollow-hole spinneret polishing device. Background Technology

[0002] The multi-leaf hollow spinneret polishing device is a special equipment for high-precision processing of spinnerets, which usually requires uniform polishing of the outer edge and complex curved surfaces of the spinneret.

[0003] Traditional grinding equipment typically uses a multi-axis robotic arm to drive a grinding head to grind the spinneret. However, the friction generated during the grinding process can cause the grinding head and spinneret to overheat, resulting in severe wear on both. Although workers may spray some coolant on the spinneret before grinding to cool it down, a small amount of coolant is insufficient to meet the cooling requirements. Prolonged grinding can still cause the grinding head and spinneret to overheat, easily leading to damage to both. Utility Model Content

[0004] The purpose of this invention is to provide a multi-leaf hollow spinneret grinding device. By setting up a spray assembly, specifically during the grinding process, a water pump is started to draw coolant into the delivery pipe and deliver it to the annular pipe, and then spray it out from the nozzle. The continuous spraying of coolant can cool and lubricate during the grinding process. Moreover, the annular pipe moves synchronously with the trajectory of the grinding head, thus maintaining uniform cooling and temperature reduction. This reduces the wear and damage to the grinding head and spinneret. It solves the problem that workers spray some coolant on the spinneret before grinding to cool it down, but a small amount of coolant is not enough to meet the cooling requirements. Prolonged grinding can still cause the grinding head and spinneret to overheat, easily leading to damage to both.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a grinding device for multi-leaf hollow spinnerets, comprising a worktable, a grinding robotic arm mounted on the top right side of the worktable, a power head at the left drive end of the grinding robotic arm, and a grinding head mounted on the motor output end of the power head via bolts, and further comprising:

[0007] A lubrication and cooling mechanism is provided on the left side of the grinding robot arm. The lubrication and cooling mechanism is used to spray coolant to assist grinding during grinding.

[0008] The grinding robotic arm is multi-axis and is used to drive the grinding head to rotate at high speed.

[0009] Furthermore, the lubrication and cooling mechanism includes a liquid storage tank installed on the top left side of the workbench, and a vacuum suction cup is installed at the center of the liquid storage tank. The vacuum suction cup is connected to a vacuum pump via a pipe.

[0010] A spraying assembly, located at the left drive end of the grinding robot arm, is used to spray liquid during grinding; and

[0011] A filter assembly is disposed inside the liquid storage tank and is used to filter the sprayed coolant.

[0012] The filter assembly is detachable and is used to separate grinding debris from coolant.

[0013] Furthermore, the spraying assembly includes an annular tube disposed on the outside of the grinding head, a support base fixedly connected to the top of the annular tube, the side of the support base facing the grinding robot arm being fixedly connected to the power head surface of the left drive end of the grinding robot arm, a delivery pipe fixedly connected to the back of the annular tube, and several nozzles installed at the bottom of the annular tube.

[0014] The annular tube is used to distribute the coolant to several nozzles, and the annular tube moves along the same trajectory as the grinding head.

[0015] Furthermore, two brackets are fixedly connected to the top of the liquid storage tank, and a drag bar is fixedly connected to the top of the brackets. A water pump is fixedly connected to the back of the liquid storage tank, and a drain pipe is fixedly connected to the left side of the liquid storage tank.

[0016] The water pump's bottom inlet is connected to a storage tank via a pipe, and the water pump's top outlet is fixedly connected to the bottom of a delivery pipe.

[0018] The inner ring protrudes from the bottom of the filter box, which is used to intercept debris.

[0019] Furthermore, after the filter box is installed inside the liquid storage tank, the bottom of the support rod contacts the bottom of the liquid storage tank, forming a storage space between the filter box and the liquid storage tank, and the inner ring of the sealing ring contacts the outer ring surface of the vacuum suction cup.

[0020] Furthermore, the delivery pipe is in contact with the towing rod, which is used to lift the delivery pipe and deliver coolant into the annular pipe.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model, by setting up a spray assembly, specifically, during the grinding process, starts a water pump to draw coolant into the delivery pipe and delivers it into the annular pipe, and then sprays it out from the nozzle. By continuously spraying coolant, cooling and lubrication can be achieved during the grinding process. Moreover, the annular pipe moves synchronously with the trajectory of the grinding head, thus maintaining uniform cooling and temperature reduction, thereby reducing the wear and damage to the grinding head and spinneret.

[0032] 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 scope of protection of the present utility model.

[0033] Please see Figures 1-4 As shown, this utility model is a multi-leaf hollow spinneret grinding device, including a worktable 1, a grinding robotic arm 11 installed on the top right side of the worktable 1, a power head set at the left drive end of the grinding robotic arm 11, and a grinding head 111 installed on the motor output end of the power head by bolts, and also includes:

[0034] Lubrication and cooling mechanism 2 is located on the left side of the grinding robot arm 11. The lubrication and cooling mechanism 2 is used to spray coolant to assist grinding during grinding.

[0035] Among them, the grinding robotic arm 11 is multi-axis and is used to drive the grinding head 111 to rotate at high speed.

[0036] The lubrication and cooling mechanism 2 includes a liquid storage tank 21 installed on the top left side of the workbench 1, and a vacuum suction cup 22 installed at the center of the liquid storage tank 21. The vacuum suction cup 22 is connected to a vacuum pump through a pipe.

[0037] The spraying assembly 23 is located at the left drive end of the grinding robot arm 11 and is used for spraying during grinding; and

[0038] Filter assembly 24 is disposed inside the liquid storage tank 21 and is used to filter the sprayed coolant.

[0039] The filter assembly 24 is detachable and is used to separate the grinding debris and coolant.

[0040] The spraying assembly 23 includes an annular tube 231 disposed on the outside of the grinding head 111. A support base 232 is fixedly connected to the top of the annular tube 231. The side of the support base 232 facing the grinding robot arm 11 is fixedly connected to the surface of the power head at the left drive end of the grinding robot arm 11. A conveying pipe 233 is fixedly connected to the back of the annular tube 231. Several nozzles 234 are installed at the bottom of the annular tube 231. During the grinding process, the water pump 213 is started to draw coolant into the conveying pipe 233 and deliver it into the annular tube 231. Then it is sprayed out from the nozzles 234. By continuously spraying coolant, cooling and lubrication can be achieved during the grinding process. The annular tube 231 moves synchronously with the trajectory of the grinding head 111, so it can maintain uniform cooling and temperature reduction, thereby reducing the wear and damage to the grinding head 111 and the spinneret.

[0041] The annular pipe 231 is used to distribute the coolant to several nozzles 234, and the annular pipe 231 and the grinding head 111 move along the same trajectory.

[0042] Two brackets 211 are fixedly connected to the top of the liquid storage tank 21, and a drag bar 212 is fixedly connected to the top of the brackets 211. A water pump 213 is fixedly connected to the back of the liquid storage tank 21, and a drain pipe 214 is fixedly connected to the left side of the liquid storage tank 21. A valve is installed on the drain pipe 214 to open and close the drain pipe 214, so as to facilitate the discharge of coolant from the liquid storage tank 21.

[0043] The bottom inlet of the water pump 213 is connected to the storage tank 21 via a pipe, and the top outlet of the water pump 213 is fixedly connected to the bottom of the delivery pipe 233.

[0044] The filter assembly 24 includes a filter box 241 positioned inside the liquid storage tank 21. An inner ring 242 is fixedly connected to the center of the filter box 241, and a sealing ring 243 is fitted inside the inner ring 242. A filter groove 244 is opened at the bottom of the filter box 241. Handles 245 are fixedly connected to the four corners of the inner side of the filter box 241, and support rods 246 are fixedly connected to the four corners of the bottom of the filter box 241. The sprayed coolant will flow into the filter box 241 along with debris. The coolant is filtered through the filter groove 244, leaving the debris on the filter box 241. The filtered coolant can then be reused, achieving the purpose of circulation. By pulling the handle 245, the filter box 241 can be lifted upwards, and the inner ring 242 will disengage from the outside of the vacuum suction cup 22, allowing the filter box 241 to be quickly disassembled and the debris on the filter box 241 to be easily cleaned.

[0045] The inner ring 242 protrudes from the bottom of the filter box 241, which is used to intercept debris.

[0046] After the filter box 241 is installed in the liquid storage tank 21, the bottom of the support rod 246 contacts the bottom of the liquid storage tank 21, so that a storage space is formed between the filter box 241 and the liquid storage tank 21. The inner ring of the sealing ring 243 contacts the outer ring surface of the vacuum suction cup 22; the sealing ring 243 inside the inner ring 242 contacts the outer side of the vacuum suction cup 22 to seal the connection.

[0047] The delivery pipe 233 is in contact with the towing rod 212, which is used to lift the delivery pipe 233. The delivery pipe 233 is used to deliver coolant into the annular pipe 231.

[0048] One specific application of this embodiment is:

[0049] In use, first pour coolant into the reservoir 21 to store coolant. Place the spinneret on the vacuum suction cup 22, and then use the internal vacuum pump to extract gas to adsorb and fix the spinneret on the vacuum suction cup 22. Then, start the power head on the grinding robot arm 11, which drives the grinding head 111 through the motor. The grinding head 111 rotates at high speed (50,000-100,000 rpm) and feeds along the spiral or radial trajectory of the hole to ensure uniform wear. A pressure sensor is installed on the grinding robot arm 11, which adjusts the feed pressure of the grinding head 111 in real time (usually controlled at 0.1-1N). 11. The grinding head 111 can be moved to the spinneret to start the grinding work. During the grinding process, the water pump 213 is started to draw coolant into the delivery pipe 233 and deliver it to the annular pipe 231. Then it is sprayed out from the nozzle 234. The continuous spraying of coolant can cool and lubricate during the grinding process. The annular pipe 231 moves synchronously with the trajectory of the grinding head 111, so it can maintain uniform cooling and temperature drop. When the grinding robot arm 11 drives the grinding head 111 to move, the delivery pipe 233 will slide on the drag bar 212. The drag bar 212 is used to support and limit the delivery pipe 233 to prevent the delivery pipe 233 from getting tangled.

[0050] Since the spinneret is installed inside the liquid storage tank 21, during the grinding process, the coolant will splash onto the inner wall of the liquid storage tank 21, with only a small amount of liquid splashing onto the outside of the liquid storage tank 21, reducing coolant waste. The sprayed coolant, along with the debris, will flow into the filter box 241 and be filtered through the filter groove 244, leaving the debris on the filter box 241. The filtered coolant can then be reused, achieving the purpose of circulation. Finally, after the grinding is completed, the grinding robot arm 11 drives the grinding head 111 to move and reset, and then the spinneret on the vacuum suction cup 22 can be removed.

[0051] When it is necessary to clean the debris on the filter box 241, pull the handle 245 to lift the filter box 241 upwards. The inner ring 242 will then disengage from the outside of the vacuum suction cup 22, allowing the filter box 241 to be quickly disassembled. Then, clean the debris on the filter box 241. After cleaning, insert the filter box 241 into the liquid storage tank 21. The inner ring 242 will then be inserted into the vacuum suction cup 22, and the sealing ring 243 inside the inner ring 242 will contact the outside of the vacuum suction cup 22 to seal the connection. When the bottom of the support rod 246 contacts the bottom of the liquid storage tank 21, the filter box 241 can be placed. The top of the inner ring 242 protrudes from the bottom of the filter box 241, which can effectively keep the debris inside the filter box 241.
