Quick adjustable clamping device for precision instrument

Abstract

The invention provides a quick adjustable clamping device for a precision instrument, and relates to the technical field of precision instrument manufacturing equipment. A base is provided with a sliding groove, a bidirectional threaded rotating shaft is arranged in the base, and one end of the bidirectional threaded rotating shaft extends out of the outer side of the base and is connected with aholding piece; a first thread section and a second thread section which are opposite in thread rotation direction are arranged on the bidirectional threaded rotating shaft; two jaw seats are arrangedabove the base, and jaws are arranged on opposite sides of the two jaw seats; sliding blocks are respectively arranged below the two jaw seats, the two sliding blocks are respectively arranged on thefirst thread section and the second thread section in a sleeving mode, and the two sliding blocks are respectively in threaded connection with the first thread section and the second thread section; two ends of each jaw seat are respectively provided with supporting blocks, and the supporting blocks are connected with the end parts of the jaw seats through adjusting bolts; and a sliding piece is arranged at the lower end of each supporting block and is attached to the side wall of the base. 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 measurement accuracy and measurement efficiency can be maintained.

Description

Technical field [0001] The invention relates to the technical field of precision instrument manufacturing equipment, in particular to a fast adjustable clamping device for precision instruments. Background technique [0002] In the field of precision instrument manufacturing, it is often necessary to use a clamping device to clamp the parts before measuring. The stability of the clamping device directly affects the accuracy and uncertainty of the measurement results. However, for ordinary clamping devices, the gap gradually increases after a period of use, and cannot be adjusted but replaced. If the clamping device is not replaced, the accuracy of the measurement result will be affected. However, if the clamping device is replaced, it will increase the cost, and it will take a longer time to replace the clamping device, which affects production and reduces production efficiency. Summary of the invention [0003] The present invention provides a fast adjustable clamping device fo...
