Description

Spring pipe surface roughness lifting device

Technical Field

The utility model relates to the technical field of spring tubes, in particular to a device for improving the surface roughness of a spring tube.

Background

The spring tube is also called a Bowden tube, and is an elastic sensitive element for measuring pressure by utilizing bending change or torsional deformation of the tube, one end of the spring tube is fixed, the other end of the spring tube is movable, the cross section of the spring tube is elliptical or flat, the tube with a non-circular cross section gradually expands into a circular shape under the action of the internal pressure of the tube, and at the moment, the movable end generates displacement with a certain relation with the pressure; the movable end drives the pointer to indicate the pressure. The most commonly used bourdon tube is of the C-type, and in addition, there are spiral, C-type combinations, and the like. The spring tube is made of copper-based or iron-based alloy, is commonly used for measuring larger pressure, and is often used in combination with other elastic elements.

In order to improve the life of spring pipe, need carry out the smearing of damping oil to the spring pipe, but because the spring pipe surface is comparatively smooth, damping oil's oil hanging ability is weaker, generally need polish the surface of spring pipe, promotes its roughness, and the efficiency of manual work polishing is lower among the prior art, and roughness promotes the effect non-uniformly, and the in-process of polishing still can cause the rejection of spring pipe.

Disclosure of Invention

In order to solve the problems in the prior art, the utility model provides a device for improving the surface roughness of a spring tube.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

the surface roughness lifting equipment for the spring tube comprises a base, wherein an elastic piece is arranged on the upper end surface of the base; the top end of the elastic piece is welded and fixed with the lower end face of the workbench, a groove is formed in the upper end face of the workbench, a through hole is formed in the workbench, a push rod is arranged in the through hole, and the bottom end of the push rod is welded and fixed on the upper end face of the base; the left and right sides of workstation is provided with the mounting bracket, mounting bracket top bolt fastening has the slide bar, slidable mounting has the polishing head about on the slide bar.

Further, the elastic piece comprises a sliding rod, a sleeve and a spring, wherein the sliding rod is installed in the sleeve in a vertical sliding mode, and the spring is sleeved outside the sliding rod.

Furthermore, a protection pad is adhered to the top end of the ejector rod.

Furthermore, the protection pad is made of sponge materials.

Compared with the prior art, the utility model has the beneficial effects that:

the spring tube clamp that will wait to polish is fixed in the type groove, then polishes the surface of type groove through polishing head, adjusts the promotion degree that polishing head can control the roughness to the type groove, and operating personnel only need push down the workstation after polishing is accomplished, and the ejector pin can upwards be ejecting the spring tube in the type groove this moment, conveniently takes out the spring tube. The utility model can adjust the lifting degree of the roughness of the outer surface of the spring tube, and is convenient and quick to take and put the spring tube in the polishing process, and has strong practicability.
