Description

Technical Field

[0001] This utility model belongs to the field of precision machining technology for structural components, and in particular relates to a precision machining device for irregularly shaped structural components based on multi-axis linkage. Background Technology

[0002] Among related technologies, a high-precision machining device for irregularly shaped structural parts, with announcement number CN217668190U, is disclosed. During precision machining, the irregularly shaped structure is placed in an electric push rod, at which point a dial indicator operates to perform standard measurements. During measurement, the push rod and force block process the structure. Once the measurement is complete, the machining is finished. The precision is standardized according to the dial indicator specifications, reducing inaccuracies in structural parts and minimizing repetitive work, thus greatly improving the efficiency of manufacturing irregularly shaped structural parts. When wastewater is generated during processing, it is collected in a sump and then transported by water pipes to a collection tank. After being filtered through a screen in the collection tank, the wastewater is converted into clean water. This clean water is then transported to the top via water pipes for secondary circulation, reducing water waste and increasing processing convenience.

[0003] However, this utility model is not convenient for clamping irregularly shaped structural parts during use, requiring workers to spend a lot of time on its installation, which increases the workload of workers and thus seriously affects work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a precision machining device for irregularly shaped structural parts based on multi-axis linkage. By setting up a clamping mechanism, the device solves the problem that it is inconvenient to clamp irregularly shaped structural parts during use, requiring workers to spend a lot of time on their installation, which increases the workload of workers and seriously affects work efficiency.

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

[0006] This utility model is a precision machining device for irregularly shaped structural parts based on multi-axis linkage, including a multi-axis machine tool, wherein the multi-axis machine tool is provided with a clamping mechanism and a separation mechanism;

[0007] The clamping mechanism includes a rotating assembly and several gripper assemblies. The rotating assembly includes a bracket one fixedly connected to the inner wall of the rear side of the multi-axis machine tool. A worm gear is rotatably connected to the inner wall of the bracket one, and a rotating shaft is rotatably connected to the inner wall of the bracket one. The gripper assembly includes a bracket two fixedly connected to the top of the bracket one. The separation mechanism includes a bracket three fixedly connected to the inner wall of the left side of the multi-axis machine tool.

[0008] Furthermore, a worm gear is rotatably connected to the outer wall of the rotating shaft, the worm gear meshes with the worm, a bevel gear is fixedly connected to the outer wall of the rotating shaft, a limit block is fixedly connected to the front side of the worm, a threaded sleeve is rotatably connected to the inner wall of the bracket, and a threaded rod is threadedly connected to the inner wall of the threaded sleeve, the threaded rod passing through the threaded sleeve.

[0009] Furthermore, a second bevel gear is fixedly connected to the outer wall of the threaded sleeve, the second bevel gear meshing with the first bevel gear, a clamping plate is fixedly connected to the side of the threaded rod near the rotating shaft, the bottom of the clamping plate is in contact with the first bracket, and a second limit block is fixedly connected to the side of the threaded rod away from the rotating shaft.

[0010] Furthermore, a filter plate is fixedly connected to the right side of the bracket three, and two brackets four are fixedly connected to the inner wall of the multi-axis machine tool. A partition net is provided on the two brackets four. A slider is slidably connected to the inner wall of the multi-axis machine tool. The bottom of the slider is in contact with the filter plate. A sliding groove is provided on the slider. The outer wall of the partition net is in contact with the sliding groove.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting up a clamping mechanism, the structural parts to be processed can be placed between several jaw assemblies at the top of the bracket during clamping. Then, the limiting block can be rotated by a wrench or other tools, which will drive the worm gear to rotate. Under the action of the worm gear, the first bevel gear will rotate through the shaft. The rotation of the first bevel gear will drive the threaded sleeve to rotate through the second bevel gear. In turn, the threaded rod will drive the clamping plate to clamp the structural parts. This makes it easier to clamp irregular structural parts that need to be processed, without requiring workers to spend a lot of time on fixing and clamping them, thereby reducing the workload of workers and increasing work efficiency.

[0013] 2. By setting up a separation mechanism, a large amount of metal chips and coolant mixture will fall from the clamping mechanism during processing. At this time, large pieces of metal will slowly fall onto the filter plate under the buffer of the mesh. Then, the coolant in the mixture will flow back into the multi-axis machine tool through the filter plate, while the metal chips will accumulate between the filter plate and the mesh. After processing, the slider can be pulled to the right to hang the metal chips between the filter plate and the mesh on the right side of the multi-axis machine tool. Then, the side door can be opened to remove the metal chips. Then, the slider can be reset to collect the cut metal chips and separate them from the coolant. This not only allows the coolant to circulate better, but also facilitates the recycling of metal chips after processing.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] Please see Figure 1-7 As shown, this utility model is a precision machining device for irregularly shaped structural parts based on multi-axis linkage, including a multi-axis machine tool 1. The multi-axis machine tool 1 is equipped with a clamping mechanism 2 and a separation mechanism 3. The clamping mechanism 2 includes a rotating assembly 21 and several jaw assemblies 22. The rotating assembly 21 includes a bracket 211 fixedly connected to the inner wall of the rear side of the multi-axis machine tool 1. A worm gear 212 is rotatably connected to the inner wall of the bracket 211. A rotating shaft 213 is rotatably connected to the inner wall of the bracket 211. The jaw assembly 22 includes a bracket 221 fixedly connected to the top of the bracket 211. A worm wheel 214 is rotatably connected to the outer wall of the rotating shaft 213. The worm wheel 214 meshes with the worm gear 212. A bevel gear 215 is fixedly connected to the outer wall of the rotating shaft 213. A limit block 216 is fixedly connected to the front side of the worm gear 212. A threaded sleeve 222 is rotatably connected to the inner wall of the second frame 221. A threaded rod 223 is threadedly connected to the inner wall of the threaded sleeve 222, and the threaded rod 223 passes through the threaded sleeve 222. A bevel gear 224 is fixedly connected to the outer wall of the threaded sleeve 222, and the bevel gear 224 meshes with the first bevel gear 215. A clamping plate 225 is fixedly connected to the side of the threaded rod 223 near the rotating shaft 213. The bottom of the clamping plate 225 contacts the first bracket 211. A limit block 226 is fixedly connected to the side of the threaded rod 223 away from the rotating shaft 213. By setting up the clamping mechanism 2, it is possible to more conveniently clamp the irregular structural parts that need to be processed, without requiring the staff to spend a lot of time on fixing and clamping them, thereby reducing the workload of the staff and increasing work efficiency.

[0027] The separation mechanism 3 includes a bracket 301 fixedly connected to the inner wall of the left side of the multi-axis machine tool 1. A filter plate 302 is fixedly connected to the right side of the bracket 301. Two brackets 403 are fixedly connected to the inner wall of the multi-axis machine tool 1. A partition net 304 is provided on the two brackets 403. A slider 305 is slidably connected to the inner wall of the multi-axis machine tool 1. The bottom of the slider 305 is in contact with the filter plate 302. A groove 306 is provided on the slider 305. The outer wall of the partition net 304 is in contact with the groove 306. By setting the separation mechanism 3, the metal chips cut off can be collected and separated from the coolant.

[0028] A specific application of this embodiment is as follows: During use, the structural component to be processed can be placed between several gripper assemblies 22 on the top of the support 211. Then, the limiting block 216 can be rotated using a wrench or other tools, causing the worm gear 212 to rotate. Under the action of the worm wheel 214, the bevel gear 215 rotates via the rotating shaft 213. The rotation of the bevel gear 215, in turn, drives the threaded sleeve 222 to rotate via the bevel gear 224. This, in turn, drives the clamping plate 225 to clamp the structural component via the threaded rod 223. At this point, the hatch of the multi-axis machine tool 1 can be closed, and the multi-axis machine tool 1 can be operated to process the structural component. The multi-axis machine tool 1 is a DMU50 five-axis lathe, which is based on CNC technology principles. The control system receives the part processing program and converts it into pulses. The impulse signal controls the servo system of each axis, drives the movement of machine tool parts, and realizes the relative movement of the tool and the workpiece. At the same time, the automatic tool changer cooperates to complete multi-process machining, realizing high-precision and automated milling. During machining, a large amount of metal chips and coolant mixture will fall from the clamping mechanism 2. At this time, the large pieces of metal will slowly fall onto the filter plate 302 under the buffer of the mesh 304. Then the coolant in the mixture will flow back into the multi-axis machine tool 1 through the filter plate 302, while the metal chips will gather between the filter plate 302 and the mesh 304. After machining is completed, the slider 305 can be pulled to the right to hang the metal chips between the filter plate 302 and the mesh 304 on the right side of the multi-axis machine tool 1. Then the side door is opened to remove the metal chips, and then the slider 305 is reset.
