Detailed Description

The structure of the present utility model will be further described by way of examples with reference to the accompanying drawings. It should be noted that the present embodiments are illustrative and not restrictive.

Referring to fig. 1 to 5, the utility model relates to a micro-cylinder fixing device on a multifunctional calibrator, which comprises the following components: comprises a fixed vertical seat 2, a clamping action sleeve 3, an expanding sleeve screw 1 and a fastening screw 4.

The fixed vertical seat is composed of a bottom plate part and a vertical plate part vertically arranged at the upper end of the bottom plate. The middle part of the lower end of the bottom plate is provided with a positioning table, and the positioning table is clamped and fixed in a positioning groove at the upper end of the multifunctional calibrator platform 5, so that the fixed mounting of the fixed stand on the multifunctional calibrator platform is realized. The middle part of the vertical plate part is provided with a mounting through hole, and the top and at least one side of the mounting through hole are respectively provided with a radial threaded hole for mounting the expansion sleeve screw and the fastening screw. Further, ribs extending along the axial direction are uniformly distributed on the wall surface of the hole of the mounting through hole along the circumferential direction, so that friction is increased and positioning matching effect is improved with the matching piece.

The clamping sleeve is an opening sleeve with a slit 3.1 axially formed on the side wall. The middle part of the slotting is provided with a radial expansion action hole 3.2 in the radial direction, and the outer end of the radial expansion action hole is a taper hole with a large inner end and a small inner end. Grooves 3.3 extending along the axial direction of the clamping sleeve are uniformly distributed on the outer surface of the clamping sleeve along the circumferential direction, and the clamping sleeve also plays roles of increasing friction with a matching piece and improving positioning matching. According to the method, three different steels including manganese silicon steel, tungsten chromium steel and nickel chromium steel are tested aiming at the material selection of the clamping sleeve, and through steel type test analysis, the nickel chromium steel is finally adopted as the material of the die assembly, so that the die assembly has the advantages of strong corrosion resistance, difficult oxidation and low cost, has certain toughness, and is suitable for laboratory use environments with high humidity.

The expansion sleeve screw consists of an external thread section 1.1 positioned at the upper part and a conical head 1.2 positioned at the lower part, and the taper of the conical head is consistent with that of a conical hole on the clamping sleeve. The diameter of the upper large end of the conical head is larger than the diameter of the large end of the tensioning action hole, and the diameter of the lower small end of the conical head is smaller than the diameter of the large end of the tensioning action hole.

The clamping sleeve is inserted into the mounting through hole on the fixed vertical seat, and in the natural state of not expanding, the outer diameter of the clamping sleeve is smaller than the aperture of the mounting through hole on the fixed vertical seat, so that a fit clearance for the clamping sleeve to expand by a certain size along the radial direction is formed between the clamping sleeve and the mounting through hole. The slit of the clamping sleeve is positioned right above the fixing seat, so that the conical hole is aligned with the top radial threaded hole on the fixing seat. The sleeve expanding screw is in threaded connection with the radial threaded hole at the top of the fixed vertical seat through the external thread section, and the conical head of the sleeve expanding screw is inserted and assembled with the conical hole on the clamping action sleeve, so that the inner hole of the clamping action sleeve expands to a size consistent with the mounting shaft part of the differential cylinder 6, and after the mounting shaft part of the differential cylinder is inserted, the differential cylinder is fastened and mounted. The fastening screw is arranged in a radial threaded hole on the side part of the fixed vertical seat, and the inner end of the fastening screw is tightly pressed on the outer wall surface of the clamping action sleeve, so that the clamping action sleeve is tightly pressed and positioned in the installation through hole of the fixed vertical seat.

The clamping sleeve in the fixing device is suitable for mounting and fixing micro-cylinders within a certain size range. If the specification and size differences of the matched and installed micro-cylinders are large, two or more clamping action sleeves with corresponding sizes can be matched to meet the installation and use of the micro-cylinders in a larger range.
