Abstract
Description
Technical Field
[0001] This utility model relates to the field of machine tool chuck technology, and in particular to a machine tool chuck mounting structure. Background Technology
[0002] Machine tool chucks are machine tool accessories used to clamp workpieces or cutting tools. They are usually mounted on a chuck and come in two-jaw, three-jaw, and four-jaw types. Three-jaw chucks (self-centering type) are suitable for quick clamping of round workpieces; four-jaw chucks (independently adjustable type) can clamp irregularly shaped or eccentric workpieces. The jaws are mostly made of alloy steel or hardened steel, and some use soft jaws (which can be machined to fit the shape of the workpiece).
[0003] When machine tool chucks need to be fixed to a machine tool, mounting holes need to be drilled on the machine tool, aligned with the threaded holes on the chuck, and then bolts are used to fix them to the machine tool.
[0004] When the machine tool chuck needs to adjust its clamping position on the machine tool, the machine tool chuck fixed with bolts needs to be removed, and then a second mounting hole aligned with the chuck needs to be drilled on the machine tool. This operation is cumbersome, the machine tool chuck cannot be quickly installed in different positions on the machine tool, and the effect is not good. Therefore, based on actual usage, we have improved the above-mentioned existing technology. Utility Model Content

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0030] Example 1
[0031] Reference Figure 1-4 This is the first embodiment of the present utility model. This embodiment provides a machine tool chuck mounting structure, including a machine tool chuck body 1, a mounting assembly 2 for mounting the machine tool chuck body 1 on the machine tool, and three sets of threaded holes 101 opened at the bottom of the machine tool chuck body 1.
[0032] Mounting component 2 includes two sets of slide rails 200 welded to the machine tool. Slide seats 202 are slidably connected to the two sets of slide rails 200. A support plate 203 is provided on the top of the slide seat 202. Three sets of ear plates 205 are installed on the outer wall of the support plate 203. Each set of ear plates 205 is provided with a fixing bolt 206 for fixing threaded holes 101. Multiple sets of positioning holes 201 are opened on the side walls of the two sets of slide rails 200. A fixing box 207 is provided at the bottom of the slide seat 202. Positioning rods 210 connected to the positioning holes 201 are slidably connected to both sides of the fixing box 207. A disassembly and assembly component 3 is provided between the slide seat 202 and the support plate 203.
[0033] The slide block 202 is fixedly connected to the support plate 203 and the fixing box 207. The two sets of positioning rods 210 inside the fixing box 207 can move in opposite or relative directions. When the slide block 202 needs to adjust its position on the slide rail 200, adjacent positioning rods 210 slide in opposite directions. At this time, the positioning rods 210 are not connected to the positioning holes 201 on the slide rail 200, allowing the slide block 202 to drive the support plate 203 to slide on the slide rail 200. After determining the position of the slide block 202, adjacent positioning rods 210 move in opposite directions, so that the positioning rods 210 are aligned with their corresponding... The positioning hole 201 is connected, which fixes the position of the slide 202 and the support plate 203. The machine tool chuck body 1 is placed on the support plate 203. The three sets of ear plates 205 are aligned with the threaded holes 101 opened at the bottom of the machine tool chuck body 1. By rotating the three sets of fixing bolts 206, they are threaded into the threaded holes 101, thus completing the fixing of the machine tool chuck body 1. The machine tool chuck can be quickly installed in different positions on the machine tool without having to open corresponding installation holes on the machine tool each time. The machine tool chuck is easy to install and the position of the machine tool chuck is easy to adjust, which improves its practicality.
[0034] Specifically, the bottom of the machine tool chuck body 1 is provided with a groove 100, and a protrusion 204 connected to the groove 100 is installed on the support plate 203; the support plate 203 and the protrusion 204 are fixedly connected, and the connection between the groove 100 and the protrusion 204 plays a limiting role in the installation of the machine tool chuck body 1.
[0035] Furthermore, two sets of sliding plates 208 are slidably connected to the inner cavity of the fixing box 207, and a compression spring 209 is installed between adjacent sliding plates 208. The outer sides of the two sets of sliding plates 208 are respectively connected to two sets of positioning rods 210. A through groove 211 is provided on the bottom wall of the fixing box 207. Two sets of moving parts 212 are slidably connected in the through groove 211. The tops of the two sets of moving parts 212 are respectively connected to the bottoms of the two sets of sliding plates 208.
[0036] The movable component 212 is fixedly connected to the slide plate 208, and the slide plate 208 is fixedly connected to the slider 213. When the slide block 202 needs to slide on the slide rail 200, the two sets of movable components 212 slide in opposite directions in the through groove 211. At this time, the compression spring 209 is compressed, and the two sets of positioning rods 210 move in opposite directions and are stored on both sides of the inner cavity of the fixed box 207. After the position of the slide block 202 is determined, the positioning rods 210 are aligned with the corresponding positioning holes 201 on the slide rail 200. The two sets of movable rods 212 are released, and the compressed spring 209 automatically returns to its original position. The two sets of slide plates 208 and positioning rods 210 move in opposite directions, so that the positioning rods 210 are connected in the corresponding positioning holes 201, thus completing the fixation of the position of the slide block 202 and the support plate 203.
[0037] Furthermore, a guide groove 214 is provided on the top wall of the inner cavity of the fixing box 207. Two sets of sliders 213 are slidably connected in the guide groove 214. The bottom of the two sets of sliders 213 are respectively connected to the top of the two sets of slide plates 208. The sliders 213 and the slide plates 208 are fixedly connected. Through the sliding connection between the sliders 213 and the slide plates 208, the movement of the slide plates 208 and the positioning rod 210 is guided and limited.
[0038] Example 2
[0039] Reference Figure 5 and Figure 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The disassembly component 3 includes a threaded connector 301 installed on the slide 202, and a threaded interface 302 adapted to the threaded connector 301 is opened in the support plate 203.
[0040] Specifically, the length of the threaded connector 301 is equal to the depth of the threaded interface 302, and the diameter of the threaded connector 301 is equal to the inner diameter of the threaded interface 302.
[0041] Furthermore, the threaded connector 301 is fixedly connected to the top of the slide 202. Through the threaded connection between the threaded connector 301 and the threaded interface 302, the slide 202 and the support plate 203 can be quickly disassembled and assembled. The size of the support plate 302 can be easily replaced to match the machine tool chuck, and it can be used for the installation of chucks of different models of machine tools with little limitation in use.
[0042] Working principle: When using this machine tool chuck structure, firstly, the two sets of slide rails 200 on the mounting component 2 are welded to the corresponding positions on the machine tool. Then, the threaded joint 201 on the slide 202 is connected to the threaded interface 302 on the support plate 203, realizing the quick assembly and disassembly of the slide 202 and the support plate 203. The size of the support plate 302 can be easily replaced to match the machine tool chuck, and it can be used for the installation of chucks of different models of machine tools with little limitation in use.
[0043] When the slide block 202 needs to slide on the slide rail 200, the two sets of moving parts 212 slide in opposite directions within the through groove 211. At this time, the compression spring 209 is compressed, and the two sets of positioning rods 210 move in opposite directions and are housed on both sides of the inner cavity of the fixing box 207. After the position of the fixing box 207 is unrestricted, the slide block 202 can slide on the two sets of slide rails 200. After determining the position of the slide block 202, align the positioning rods 210 with the corresponding positioning holes 201 on the slide rail 200, release the two sets of moving rods 212, and allow the compressed compression spring 209 to automatically return to its original position. The two sets of sliding plates 208 and positioning rods 210 move in opposite directions. Moving in the opposite direction, the positioning rod 210 is connected to the corresponding positioning hole 201, thus fixing the positions of the slide 202 and the support plate 203. Then, the machine tool chuck body 1 is placed on the support plate 203, and the three sets of ear plates 205 are aligned with the threaded holes 101 opened at the bottom of the machine tool chuck body 1. By rotating the three sets of fixing bolts 206, they are threaded into the threaded holes 101, thus fixing the machine tool chuck body 1. The machine tool chuck can be quickly installed in different positions on the machine tool without having to open corresponding installation holes on the machine tool each time. The machine tool chuck is easy to install and the position of the machine tool chuck is easy to adjust, which improves its practicality.
