Detailed Description
As shown in fig. 1 to 4, the utility model discloses a high accuracy long distance adjustment measuring contrast measuring tool, including mobile jib 1, fixed block 2 on the mobile jib is located to the preface cover, first clamping jaw 3, fine setting subassembly 4 and second clamping jaw 5, wherein fixed block 2 and first clamping jaw 3 are located the one end of mobile jib 1, fine setting subassembly 4 and second clamping jaw 5 are located the other end of mobile jib 1, first clamping jaw 3, fine setting subassembly 4 and second clamping jaw 5 all can be followed mobile jib 1 and slide and pass through bolt 6b separately, 6c, 6d is fixed in on the mobile jib 1, be equipped with amesdial 10 on the first clamping jaw 3, the bullet needle 101 of amesdial 10 contacts fixed block 2 along the direction of the axis that is on a parallel with mobile jib 1, the direction pin joint along the axis of mobile jib 1 on the fine setting subassembly 4 has adjusting bolt 41, adjusting bolt 41's terminal threaded connection is on second clamping jaw 5. When the time is zero, the fixed block 2 and the first clamping jaw 3 are fixed by bolts 6a and 6b, and the dial indicator 10 is positioned at the zero point; then clamping a standard value block between the first clamping jaw 3 and the second clamping jaw 5, enabling the first clamping jaw and the second clamping jaw to just clamp the standard value block through the fine adjustment assembly 4, determining the standard length, and then removing the standard value block; then the second clamping jaw 5 and the fine adjustment assembly 4 are fixed in position by bolts 6c and 6d, the bolt 6c of the first clamping jaw 3 is loosened, then the workpiece to be measured is clamped between the first clamping jaw 3 and the second clamping jaw 5, because the position of the second clamping jaw 5 is unchanged, if the workpiece is longer than a standard value, the first clamping jaw 3 moves towards one side of the fixed block 2, and under the reaction force of the fixed block 2 to the elastic needle 101, the dial indicator 10 displays the reading of the deviation to achieve the high precision of 0.001 mm. In practical application, the length of the main rod 1 can be 700-1000 mm. When aiming at workpieces with larger size difference, the fine adjustment assembly 4 and the second clamping jaw 5 can slide along the main rod 1 relatively far so as to complete a relatively zero procedure. The measuring tool can measure the workpiece being processed on the machine table, the workpiece being used on the equipment and the processed workpiece after being compared with zero, and is flexible to use.
As shown in fig. 3, the adjusting bolt 41 is further provided with a fixing nut 42 for abutting against the second jaw 5. When the clamping force is zero, the fixing nut 42 needs to be loosened in a direction away from the second clamping jaw 5, so that the adjusting bolt 41 has an adjusting space; after zeroing, the second jaw 5 is abutted by the adjusting bolt 41, so that the detection accuracy can be prevented from being affected by slight rotation of the two.
As shown in fig. 1 and 2, the fixing block 2 is also adjustably fixed to the main rod 1 by a bolt 6 a. Thus, the assembly and fixation of the fixing block 2 are facilitated.
As shown in fig. 4, the main rod 1 has a hollow structure. Therefore, the main rod 1 is light in weight and convenient to use.
As shown in fig. 1 to 4, end caps 9a, 9b having an outer diameter larger than that of the main lever 1 are screwed to both ends of the main lever 1. The end caps 9a, 9b prevent parts sliding on the main lever 1 from falling out of both ends of the main lever 1.
As shown in fig. 2 and 4, the main rod 1 is provided with a limiting groove 11 at a side close to the first clamping jaw 3, and the first clamping jaw 3 is provided with a limiting screw 7 penetrating into the limiting groove 11. The limiting screw 7 can ensure that the first clamping jaw 3 can only move along the axial direction of the main rod 1 and can not rotate, so that the elastic needle 101 of the dial indicator 10 can be supported at the same position of the fixed block 2, and the reading is accurate.
As shown in fig. 2 and 4, the first jaw 3 further has a through hole 31 for allowing the limiting groove 31 to open to the atmosphere. The through hole 31 can avoid the problem that the first clamping jaw 3 is not smooth in movement due to air trapping inside the limiting groove 31, and inaccurate measurement is avoided.
As shown in fig. 1 to 4, the top of the first jaw 2 and the second jaw 4 are each provided with an insert 8a, 8b of higher strength than the material of the first jaw 2 and the second jaw 4. The inserts 8a and 8b can ensure that the first clamping jaw 2 and the second clamping jaw 4 have smaller elastic deformation when clamping a workpiece, avoid the deformation from bringing too high measurement errors, and ensure the high precision of the measuring tool.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
