Description

Technical Field

[0001] The present invention relates to the technical field of spindle shaft detection, and in particular to a spindle shaft testing device for a static pressure spindle. Background Art

[0002] Hydrostatic spindles are widely used in mechanical processing, especially in situations that require high precision, high stability and long life. For example, in ultra-precision processing, high-speed cutting, grinding and other fields, hydrostatic spindles play an important role. As a key component in mechanical processing, the precision of the hydrostatic spindle directly affects the quality of the workpiece. Through testing, it can be verified whether the hydrostatic spindle meets the precision requirements, thereby ensuring safe use during the working process. Therefore, a spindle shaft testing device for hydrostatic spindles is needed.

[0003] After the main shaft body of the hydrostatic spindle is processed or used for a period of time, it is usually necessary to test the shaft body. During the test, the shaft body will remain in a horizontal state, which can facilitate the inspection of the two sides and the top surface of the shaft body. Since the bottom of the shaft body needs to be supported, it is difficult to inspect the bottom surface of the shaft body at the same time. Even if the bottom surface is turned over and then tested, errors may occur in the test position or results. In addition, the shaft body is easily affected by external forces, resulting in depressions on the outer surface. The location of some depressions is small and difficult to test. In addition, when the shaft body works for a long time, the outer surface may also be worn. The test results are difficult to display intuitively during the wear test. For this reason, a spindle shaft testing device for a hydrostatic spindle is proposed. Summary of the invention

A positioning nut 314 is threadedly connected to the top of the positioning rod to clamp the linkage rod 313 to prevent loosening. A sleeve rod is connected to a spring at one end of the linkage rod 313 to always keep the magnetic rod 312 in horizontal movement and then magnetically connected to the electromagnetic block 311. The magnetic rod 312 is fixedly installed on the top surface of the sleeve rod Electromagnetic blocks 311 are symmetrically installed on both sides of the magnetic rod 312, and the electromagnetic blocks 311 are fixedly installed on the adjusting disk 31. The moving rod 315 is installed on the other end of the linkage rod 313. The bottom rotating ring 32 and the adjusting handle 333 are correspondingly provided with threaded holes and plug-in holes. The bottom end of the moving rod 315 is threadedly connected in the threaded hole to facilitate pushing the bottom rotating ring 32 to rotate, thereby pushing the cleaning rod 322 forward. The top end of the moving rod 315 is plugged into the plug-in hole, and the top end is also threadedly connected with an external nut 316 to fix the moving rod 315 and the adjusting handle 333, so as to achieve the effect of stably pushing the inner rotating disk 332.

[0061] Working principle: before testing the main shaft body, first place the arc clamping piece 26 in the arc placement frame 24, and then control the third motor to rotate. The rotation of the third motor will drive the clamping screw 234 to rotate. The rotation of the clamping screw 234 drives the movable rod 232 to descend, and the insertion rod 233 will be inserted into the connecting block 261. At this time, the arc clamping piece 26 is fixed in the arc placement frame 24, and the shaft body is placed in the arc clamping piece 26. Then, the other half of the arc clamping piece 26 is placed on the top surface of the shaft body, and the two arc clamping pieces 26 are screwed together. The shaft body will be firmly clamped, and then the right-angle bending rod is inserted into the extension rod 25 and then the core body 251 is inserted between the extension rod 25 and the right-angle bending rod, and the positioning shell 252 is used to limit the position of the core body 251. At this time, the winding motor 141 is controlled to rotate, and the winding roller 14 will pull the pull rope 15 upward. When the shaft body rotates to a vertical state, it is wound up. The motor 141 stops, and the connecting frame 22 is also in a vertical state. Then the supporting shells 21 on both sides of the bottom rod 231 are disassembled. After the disassembly is completed, the second motor 17 is controlled to rotate, thereby driving the rotating seat 112 to rotate, and the winding motor 141 is controlled to rotate at the same time. The pull rope 15 will be slowly lowered. Due to the loss of the support of the supporting shell 21, the entire fixing frame 23 will move downward, and the bottom end of the shaft body will gradually approach the rotating seat 112 and be threadedly connected in the connecting groove 115. When the bottom end of the shaft body is completely connected in the connecting groove 115, the winding motor 141 and the second motor 17 are controlled to stop moving at the same time, and then the third motor is controlled to rotate again, the movable rod 232 will move upward, the plug rod 233 will be separated from the connecting block 261, and then the winding motor 141 is controlled to rotate again, the fixing frame 23 is put back to the horizontal state, and then the arc-shaped clamping pieces 26 on both sides are disassembled. At this time, the shaft body is in a vertical state;

[0062] When the outer surface of the shaft needs to be inspected:

[0063] The first motor 111 is controlled to rotate, and the lifting screw rods 16 on both sides of the device frame 1 will start to rotate, and the adjusting disk 31 will gradually move downward. When it moves to the specified position, one end of the moving rod 315 is threadedly connected to the bottom rotating ring 32, and then the magnetic rod 312 is pushed to the other side, and the other end of the linkage rod 313 will push the bottom rotating ring 32 forward. At this time, the magnetic rod 312 will be attached to the electromagnetic block 311 on the other side, and the electromagnetic block 311 is controlled to be energized, and the magnetic rod 312 will be firmly adsorbed, and then the positioning nut 314 is used to fix the position of the linkage rod 313, so as to firmly support the bottom rotating ring 32 to prevent it from loosening. In the process of pushing the bottom rotating ring 32 forward, the arc groove 3 23 will move, the cleaning rod 322 will move along the arc groove 323, so as to achieve the effect of extending forward, the wiping strip is installed on the cleaning rod 322 in advance, and the wiping strip will contact the outer surface of the shaft body when the cleaning rod 322 is extended, and the second motor 17 is controlled to start rotating, and the wiping strip will wipe the circumference of the shaft body, and at the same time, the lifting screw rod 16 is controlled to rotate slowly, and the adjustment disk 31 will start to move upward at a uniform speed, so as to clean the outer surface of the shaft body. After reaching the designated position on the upper side, the lifting screw rod 16 is controlled to reverse and perform secondary cleaning again. If the shaft body has been used for a period of time, the wiping strip can be replaced with a peeling strip to clean the impurities corroded on the outer surface;

[0064] After the cleaning is completed, the electromagnetic block 311 is controlled to lose power, and the positioning nut 314 is loosened, the linkage rod 313 is rotated back to its original position, the moving rod 315 is rotated upward and inserted into the adjusting handle 333. After it is fully inserted, the outer nut 316 is connected to the top of the moving rod 315 to completely fix the adjusting handle 333, and then the above operation is repeated to push the adjusting handle 333 forward. The electromagnetic block 311 on one side fixes the magnetic rod 312 again, so that the positioning nut 314 clamps the linkage rod 313. During the process of pushing the adjusting handle 333 forward, the synchronization block 343 will move along the slide groove, and the test piece 34 will move forward, so that one end of the test touch rod 341 contacts the outer surface of the shaft body and continues to move forward. At this time, the test touch rod 341 will compress the spring at the tail end. After being compressed for a certain distance, one end of the metal touch rod 346 will be connected to the conductive groove of the conductive contact ring 344. At this time, the current at both ends can pass smoothly, and the corresponding indicator light 345 at the tail end will light up. When all the indicator lights 345 are on, the test can be started. The second motor 17 is controlled to rotate again, and the shaft body will slowly rotate. At this time, the test piece 34 will test the annular surface of the shaft body. If there is a recessed position, the test touch rod 341 will be connected to the recessed position under the action of the spring. At this time, the end of the metal touch rod 346 will move out of the conductive groove. At this time, the current will be broken and the indicator light 345 at the corresponding position will go out. Under continuous rotation, every time the test touch rod 341 at the corresponding position moves to the recessed groove, the corresponding indicator light 345 will go out, indicating that there is a problem at this position. Then the lifting screw 16 is controlled to rotate again, and the test piece 34 will slowly detect the outer surface of the shaft body. If only a single short indicator light 345 goes out, it means that a small-scale recess or protrusion appears in the area. If multiple indicator lights 345 go out at the same time, it means that a large-scale recess or protrusion appears in the area and needs to be processed in time. If there is no problem throughout the process, it means that the quality is intact.

[0065] This embodiment 2:

[0066] Reference Figure 21-23 , based on Example 1, the following technical solution is also provided:

[0067] A plurality of electrically-controlled lifting legs 41 are installed on the outer side of the supporting bottom block 13 to facilitate the height adjustment of the lifting base frame 42 so as to lift the shaft body. The lifting base frame 42 is installed on the telescopic end of the electrically-controlled lifting legs 41. The top ends of both sides of the lifting base frame 42 are provided with electrically-controlled rollers 43 to drive the shaft body to rotate. A plurality of disassembly frames are installed on the bottom surface of the test top frame 44. The outer sides of the disassembly frames are provided with plugs, which are connected to the lifting base frame 42 to act on the positioning of the test top frame 44. A resistance block 47 is fixedly installed on the bottom surface of the test top frame 44. The resistance block 47 is a rubber block. The bottom end of the resistance block 47 is connected to the top surface of the shaft body. A paper roll 45 of a test paper 48 is provided on the outer surface of one of the rotating rollers 46. One end of the paper roll 45 bypasses the bottom end of the resistance block 47 and is rolled on the outer surface of another rotating roller 46 to facilitate the collection of the test paper 48.

[0068] Working principle: After the above test is completed, the adjustment test mechanism 3 is lifted back to the top of the device frame 1, and then the arc-shaped clamping piece 26 is fixed to the outside of the shaft body, and the second winding motor 141 is controlled to rotate. The pull rope 15 thereon will pull the fixing frame 23 on the other side, and then make the arc-shaped placement frame 24 fit with the arc-shaped clamping piece 26, and then control the insertion rod 233 to move to position the arc-shaped clamping piece 26. After positioning is completed, the second motor 17 is controlled to rotate. Since the shaft body is clamped, the rotating seat 112 rotates while the pull rope 15 lifts the fixing frame 23 upwards, and the shaft body separates from the rotating seat 112, and then the second motor 17 stops rotating. After the shaft body is detached, the support The support shell 21 is installed on the bottom rod 231, and then the pull rope 15 is continuously released to place the fixed frame 23 into the support bottom block 13. After completion, the arc clamping piece 26 is removed, and then the electric-controlled lifting leg 41 is controlled to start to extend, and the lifting base frame 42 will be extended upward. The electric-controlled rollers 43 at both ends will lift the shaft body a certain distance, and then the test top frame 44 is installed on the lifting base frame 42. At this time, the test paper 48 will contact the top surface of the shaft body, and the electric-controlled rollers 43 are controlled to rotate, and the shaft body will rotate. During the rotation, it continues to contact with the test paper 48. If there are scratches on the outer surface of the shaft body, the rough area will scratch the test paper 48, which can intuitively reflect whether the shaft body is worn.
