Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-6, the fast adjustable clamping device for the precision instrument in the embodiment comprises a base 1, wherein the base 1 is made of medium carbon steel No. 45 steel, the surface of the base is ARCOR PC2, and the thickness of a compound layer is 12-20 um. Referring to fig. 1-3, the base 1 is provided with a fixing hole 21 for installing the base 1 on a measuring machine. The base 1 is provided with a sliding groove 2, and the sliding groove 2 is formed by downwards recessing the upper surface of the base 1. And a bidirectional threaded rotating shaft 3 is arranged in the sliding groove 2, and the length direction of the bidirectional threaded rotating shaft 3 is the same as that of the sliding groove 2. One end of the bidirectional threaded rotating shaft 3 extends out of the outer side of the base 1 and is connected with the holding piece 4, and the bidirectional threaded rotating shaft 3 can be rotated by rotating the holding piece 4. Here, the grip 4 is a hand wheel. The bidirectional threaded rotating shaft 3 is provided with a first threaded section 5 and a second threaded section 6, and the thread directions of the first threaded section 5 and the second threaded section 6 are opposite.
Two jaw seats 7 are arranged above the base 1, wherein the lower ends of the two jaw seats 7 are jointed with the upper surface of the base 1, and the two jaw seats 7 can slide along the upper surface of the base 1. Referring to fig. 4, the opposite sides of the jaw seats 7 are provided with jaws 8.
Sliding blocks 9 are respectively arranged below the jaw seats 7, the sliding blocks 9 are respectively sleeved on the first thread section 5 and the second thread section 6, and the sliding blocks 9 are respectively in threaded connection with the first thread section 5 and the second thread section 6. Namely, one jaw seat 7 is disposed on the first thread section 5 through a slide block 9 therebelow, and the other jaw seat 7 is disposed on the second thread section 6 through a slide block 9 therebelow. Thus, when the bidirectional threaded rotating shaft 3 rotates, since the sliding block 9 is located in the sliding groove 2 and is limited by the sliding groove 2 and cannot rotate along with the bidirectional threaded rotating shaft 3, the sliding block 9 can move along the length direction of the bidirectional threaded rotating shaft 3, and the sliding block 9 can move along the length direction of the sliding groove 2. Due to the fact that the thread directions of the threads of the first thread section 5 and the second thread section 6 are opposite, the two sliding blocks 9 slide in opposite directions, and therefore the two jaw seats 7 slide in opposite directions.
Two ends of the jaw seat 7 are respectively provided with a supporting block 10, and the supporting blocks 10 at two sides are respectively positioned at two sides of the base 1. The supporting block 10 is connected with the end part of the jaw seat 7 through an adjusting bolt 11, and the position of the supporting block 10 can be adjusted through the adjusting bolt 11, so that the position of the jaw seat 7 is adjusted. In this embodiment, the adjusting bolt 11 is a butterfly bolt; two butterfly bolts are arranged on each supporting block 10. Here, two butterfly bolts on each support block 10 are arranged up and down, and the two butterfly bolts are not on the same vertical line; i.e. the upper thumb bolt is located obliquely above the lower thumb bolt. Referring to fig. 4 and 5, the adjusting screw holes for installing the butterfly bolts on the jaw seat 7 and the supporting block 10 are also vertically arranged, and the upper adjusting screw hole is positioned obliquely above the lower adjusting screw hole.
The jaw seat 7 and the supporting blocks 10 at the two ends form a portal frame which is erected on the base 1. The lower end of the supporting block 10 is provided with a sliding part 12, and the sliding part 12 is attached to the side wall of the base 1. When the jaw seat 7 slides along the sliding block 9, the supporting block 10 slides along the sliding block, and the sliding piece 12 can improve the smoothness of sliding between the supporting block 10 and the base 1.
In this embodiment, the sliding member 12 is a deep groove ball bearing. Referring to fig. 5 and 6, a bearing groove 13 is provided at a lower end of the support block 10, the bearing groove 13 penetrating the support block 10 in a lateral direction; the bottom end of the supporting block 10 is provided with an upwardly recessed pin hole 14, and the pin hole 14 penetrates through the bearing groove 13. The deep groove ball bearing is arranged in the bearing groove 13, a supporting pin 15 is arranged in the pin hole 14, and the supporting pin 15 penetrates through the center of the deep groove ball bearing. Namely, the deep groove ball bearing is fixed on the supporting block 10 by the supporting pin 15, and the supporting pin 15 is in interference fit with the deep groove ball bearing. In this embodiment, the lower end of each support block 10 is provided with two deep groove ball bearings, and the two deep groove ball bearings are arranged at the same height. The sliding stability can be improved by arranging the two deep groove ball bearings.
In this embodiment, a limiting sliding groove 16 is arranged at the lower end of the base 1, and the limiting sliding groove 16 is recessed upwards from the lower surface of the base 1; the limiting sliding groove 16 is communicated with the sliding groove 2. The length of the limit runner 16 is the same as the length of the slide groove 2, but the width of the limit runner 16 is larger than the width of the slide groove 2. The lower extreme of sliding block 9 is provided with limiting plate 17, the width of limiting plate 17 is greater than the width of sliding block 9, and the both ends of limiting plate 17 are stretched out from the both ends of sliding block 9 promptly. The limiting plate 17 is slidably disposed in the limiting chute 16, and the upper end of the limiting plate 17 abuts against the top of the limiting chute 16. In this embodiment, the sliding block 9 and the limiting plate 17 are made of brass and are integrally formed into a brass block structure, and the brass block is fixed to the lower end of the jaw seat 7 by an inner hexagonal socket head cap screw 18.
In this embodiment, the two ends of the sliding groove 2 are respectively connected with an extending groove 19, and the two ends of the bidirectional threaded rotating shaft 3 respectively extend out of the extending grooves 19 on the two sides to the outside of the base 1. A closed ring 20 is arranged at one end of the bidirectional threaded rotating shaft 3 which is not connected with the holding piece 4; the closed ring 20 can limit the end of the bidirectional threaded rotating shaft 3, and the bidirectional threaded rotating shaft 3 is prevented from being drawn out.
In this embodiment, after the assembly is completed, in the case of rotating the handwheel, the four butterfly bolts at the two ends of each jaw seat 7 are tightened little by little in a diagonal opposite order until the two jaws 8 are combined without a gap and the handwheel is rotated smoothly.
When the double-thread wrench is used, the hand wheel is rotated to drive the double-thread rotating shaft 3 to rotate, so that the two jaw seats 7 are driven to move oppositely or backwards, and the two jaws 8 are clamped and loosened. After a period of use, when discovering that there is unsmooth sensation when rotating the hand wheel, or when discovering that there is a clearance when keeping silent 8 closed, adjust this embodiment. Firstly, the hand wheel is rotated to close the jaw 8, and then the eight butterfly bolts at the two sides of the two jaws 8 are all unscrewed. The hand wheel is then rotated in the direction of the screw closing the two jaws 8, while the other hand pinches the two jaws 8 towards each other, bringing the two jaws 8 together without play. Then, the four butterfly bolts at the two ends of each jaw 8 seat are finely adjusted and tightened point by point according to the opposite order of the diagonals until the two jaws 8 are combined without a gap and the hand wheel is rotated smoothly. After the clamping device is used for a period of time, the clamping device can be conveniently adjusted, so that the clamping device always keeps high precision; therefore, cost investment and time investment caused by replacing the clamping device are saved, and the accuracy and the efficiency of measurement can be kept.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
