Technical Field

[0001] The utility model relates to the technical field of machine tool production, in particular to a special fixture plate for guide rail debugging. Background Technique

[0002] In the fields of machining and machine tools, the precise debugging of guide rails plays a crucial role in ensuring the machining accuracy of machine tools. The guide rails of common machine tools are divided into inlaid steel guide rails and linear guide rails. Linear guide rails generally have a higher rated load than linear bearings, and can also bear a certain torque, and can achieve high-precision linear motion under high load. Linear guide rails are installed on many ultra-high-speed CNC machine tools.

[0003] The invention patent with the publication number of CN101648342B discloses an installation method for a machine tool guide rail. This invention directly prepares an installation surface on the machine tool bed body by scraping, eliminating the dependence on the reference surface of the bed body during the installation of the guide rail, thus greatly reducing the requirements for the machining accuracy of the machine tool bed body, not only reducing costs, but also changing the previous installation method, reducing the installation difficulty, solving the double problems brought by the machining and installation of the bed body, and having practical positive significance.

[0004] With the iteration of technology, during the current machine tool assembly process, it is often necessary to install the linear guide rail at a certain inclination angle of the guide rail seat. This makes the adjustment work during the installation of the linear guide rail difficult. During adjustment, the linear guide rail has no restraint or device for fixation, resulting in low efficiency during adjustment, and the operation steps during adjustment are extremely complex.

Detailed implementation manners

[0018] In order to make the purpose, technical solutions and advantages of the present 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 only used to explain the present utility model and are not used to limit the present utility model.

[0019] As Figures 1 to 4 shown, a special fixture plate for guide rail debugging includes a linear guide 101 and a telescopic rod 102. Both ends of the telescopic rod 102 are provided with mobile ends. Support plates 202 are respectively and fixedly installed on the two mobile ends of the telescopic rod 102. The support plates 202 are symmetrically arranged on the telescopic rod 102. A pulling handle 201 is fixedly installed on the support plate 202. Both ends of the pulling handle 201 are respectively fixed on two different support plates 202. A folding mechanism is arranged on the pulling handle 201 to enable the pulling handle 201 to move along with the support plate 202. A limiting chute is arranged on the support plate 202. An intermediate worm 214 is rotatably installed on the support plate 202. One end of the intermediate worm 214 is fixedly installed with a rotating handle 215. The other end of the intermediate worm 214 is provided with a rotating worm. An intermediate worm gear 213 is meshingly installed on the rotating worm. A telescopic shaft 212 is fixedly installed on the intermediate worm gear 213. The telescopic shaft 212 is rotatably connected to the support plate 202. Both ends of the telescopic shaft 212 are mobile ends. Telescopic worms 211 are also fixedly installed on the two mobile ends of the telescopic shaft 212.

[0020] As Figures 4 to 6As shown, a side bracket 204 is rotatably installed on the telescopic worm 211. The side bracket 204 is also slidably connected to the support plate 202. The side bracket 204 is arranged in the limit chute. An expansion frame 203 is also arranged between the symmetrically arranged side brackets 204. The expansion frame 203 is used to connect the symmetrically arranged side brackets 204. The expansion frame 203 is slidably connected to the side brackets 204 on both sides. One end of the side bracket 204 away from the support plate 202 is also fixedly installed with an outer soft magnet 205. A plurality of inner soft magnets 206 are fixedly installed in the outer soft magnet 205. The plurality of inner soft magnets 206 are symmetrically arranged in the outer soft magnet 205. A fixed magnetic pole 208 is fixedly installed between the two inner soft magnets 206. A rotating shaft 209 is also rotatably installed on the outer soft magnet 205. The rotating shaft 209, one end of the rotating shaft 209 is fixedly installed with a rotating shaft worm gear 210. The rotating shaft worm gear 210 meshes with the telescopic worm 211. One end of the rotating shaft 209 is fixedly installed with a rotating magnetic pole 207. The rotating magnetic pole 207 is arranged between the inner soft magnets 206. The two sides of the rotating magnetic pole 207 are in contact with the inner soft magnets 206 in the initial state. The materials of the fixed magnetic pole 208 and the rotating magnetic pole 207 are both strong magnetic materials. The two ends of the rotating magnetic pole 207 in contact with the inner soft magnets 206 are the two magnetic poles on the rotating magnetic pole 207. In the initial state, the fixed magnetic pole 208 and the rotating magnetic pole 207 are in a parallel state. The magnetic poles of the fixed magnetic pole 208 and the rotating magnetic pole 207 are in the same direction in the initial state. As Figure 5 shown in the magnetic pole directions of the rotating magnetic pole 207 and the fixed magnetic pole 208 in the initial state. At this time, the magnetic pole directions of the rotating magnetic pole 207 and the fixed magnetic pole 208 are opposite. Then a large magnetic field will be formed between the fixed magnetic pole 208 and the rotating magnetic pole 207. The magnetic field passes through the S pole of the fixed magnetic pole 208 through the inner soft magnet 206 to the N pole of the rotating magnetic pole 207. Then the S pole of the rotating magnetic pole 207 passes through the inner soft magnet 206 on the other side and then reaches the N pole of the fixed magnetic pole 208. In this way, a closed loop is formed through the rotating magnetic pole 207, the fixed magnetic pole 208, and the inner soft magnet 206. Then the magnetism of the inner soft magnet 206 will not expand outside the outer soft magnet 205. Then the outer soft magnet 205 will not magnetically attract the object in contact with the outer soft magnet 205. When the rotating magnetic pole 207 is rotated and the rotating magnetic pole 207 is rotated by 180 degrees, at this time, the fixed magnetic pole 208 and the rotating magnetic pole 207 will be separated from a large overall magnetic field into two small magnetic fields. At this time, the rotating magnetic pole 207 can drive the inner soft magnet 206 to form a small magnetic field to magnetically adsorb the object outside the outer soft magnet 205.

[0021] Working principle: When this device is in use, the user can use it by holding the pulling handle 201 with the hand, or by connecting the hoisting device to the pulling handle 201. Then, make the outer soft magnet 205 contact the surface of the linear guide 101. After that, manually rotate the rotating handle 215. The rotating handle 215 will drive the telescopic worm 211 to rotate through the intermediate worm gear 213 and the telescopic shaft 212. The telescopic worm 211 will continue to drive the rotating shaft worm gear 210 to rotate. The rotating shaft worm gear 210 will then drive the rotating magnetic pole 207 to rotate 180 degrees through the rotating shaft 209. At this time, after the rotating magnetic pole 207 rotates, it will form two small magnetic fields with the fixed magnetic pole 208 respectively. In this way, one end of the inner soft magnet 206 close to the rotating magnetic pole 207 and the rotating magnetic pole 207 can form a magnetic field together. The linear guide 101 in contact with the outer soft magnet 205 will be adsorbed by this magnetic field, so that the outer soft magnet 205 and the linear guide 101 can be fixed to complete the clamping process of this device on the linear guide 101.

[0022] And then, the device can be manually pulled for movement or transfer. At this time, the distance between the support plate 202 and the linear guide 101 can be adjusted by manually pulling the support plate 202. The telescopic frame 203 and the telescopic rod 102 will both expand and contract, so that the span of this device can be adjusted after adjusting the span of this device. The stability between the spans is stabilized by the friction between the telescopic rod 102 and the slider of the telescopic frame 203. When not driven by external force, the telescopic rod 102 and the telescopic frame 203 will not contract. In this way, the device can be more conveniently installed on the inclined guide rail. Then, the linear guide 101 can be installed on the machine tool guide rail seat through bolts.

[0023] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
