Embodiment 1

[0038] A floating pressing mechanism in this embodiment includes a support frame for supporting the whole mechanism. The upper and lower end surfaces of the support frame are horizontal planes parallel to each other, and the upper end is provided with a convex edge extending to one side. A cylinder is provided, the cylinder rod of the cylinder is vertically downward, the bottom end of the cylinder rod is detachably connected with a vertical connecting rod, and a connecting sleeve is slidably connected to the bottom end of the connecting rod, and a connecting sleeve is provided outside the connecting sleeve. Compression spring, the compression spring is sleeved outside the connecting rod and its inner ring is in clearance fit with the outer ring of the connecting sleeve. The bottom end of the connecting sleeve is fixedly connected with a compression block, and the four can rotate freely. The pressing wheels are symmetrically arranged on the left and right sides of the bottom sur...

Embodiment 2

[0043] On the basis of the first embodiment above, as a preference, the specific structure of the support frame is: including a vertical plate and a cylinder seat plate, the vertical plate is vertically arranged, and the parallelism between the bottom surface and the top surface is required to be 0.01mm, And its bottom surface and top surface are provided with connecting screw holes; the cylinder seat plate is used to carry the cylinder, and is horizontally arranged on the top surface of the vertical plate, and one end of the top surface of the cylinder seat plate near the edge is opened for Through hole through the cylinder rod.

[0044] Preferably, the connecting rod is a threaded rod, and one end connected to the cylinder is locked by a nut to limit the axial direction, and the other end is provided with a through hole in the radial direction for passing through the limit pin. The shape of the longitudinal section of the hole is a circle with the same diameter as the width ...

Embodiment 3

[0049] On the basis of the second embodiment above, as a preference, the specific structure of the connecting sleeve is a flange structure, the small-diameter section of the flange faces upward, and strip-shaped passages are symmetrically opened along the radial direction of the small-diameter section. hole, and the small-diameter section is a hollow tubular structure, the two ends of the limit pin are located in the strip-shaped through-hole and can freely slide up and down in the strip-shaped through-hole without falling off; There is a stepped through hole in the center of the large diameter section of the flange, which can pass through the connecting screw and limit the axial direction. There is an annular array of through holes around the stepped through hole, which is used to pass the fastener to connect the connecting sleeve to the described The compression block secures the connection.

[0050] As a preference, a V-shaped groove is opened in the center of the bottom su...

Abstract

The invention discloses a floating pressing mechanism and a using method thereof. The floating pressing mechanism comprises a supporting frame, an air cylinder, a connecting rod, a compression spring,a connecting sleeve, a pressing block and pressing wheels; and the supporting frame is used to support the entire mechanism, the air cylinder is vertically arranged on the supporting frame, the connecting rod is vertically arranged, the top end of the connecting rod is detachably connected with the bottom end of an air cylinder rod of the air cylinder, the bottom end thereof is slidably connectedin the connecting sleeve, the compression spring is arranged outside the connecting rod in a sleeving mode, the inner ring of the compression spring is in clearance fit with the outer ring of the connecting sleeve, the pressing block is fixedly connected to the bottom end of the connecting sleeve, and the four pressing wheels are symmetrically arranged on the left side and the right side of the bottom surface of the pressing block, and the bottom surfaces of the pressing wheels are beyond the bottom surface of the pressing block. The floating pressing mechanism can be used as a detection andpositioning auxiliary device of an elongated shaft type and pipe type workpiece, and the rotation follow-up and adjustable pressure requirements of the workpiece are met; and meanwhile, the floating pressing function is also achieved, the workpiece is always in a free state in the rotation process, and introduction of large errors is avoided.

Description

technical field [0001] The invention relates to the technical field of mechanical design, in particular to a floating pressing mechanism and a use method thereof. Background technique [0002] In mechanical processing, for the processing or inspection of shaft and pipe workpieces, especially the inspection of workpieces whose outer circle is used as the reference, it is usually necessary to locate the workpiece. [0003] In the prior art, V-shaped grooves are generally used for positioning, but when it is necessary to apply a compressive force to the workpiece in the radial direction, and at the same time keep the workpiece in a rotating state for detection, there is often no suitable clamping mechanism. [0004] Therefore, it is urgent to design a pressing mechanism that can apply a variable pressing force to the workpiece without affecting the rotation of the workpiece, so as to meet the detection requirements for shaft and pipe workpieces.
