Description

Technical Field

[0001] This utility model belongs to the field of metal cylinder liner technology, and in particular relates to a tooling for measuring the dimensions of metal cylinder liners. Background Technology

[0002] Metal cylinder liners are key components in industrial equipment (such as mud pumps and engines) used to support the reciprocating motion of pistons or plungers. Their core feature is that they are made of metal materials (or metal-based composite materials) and have characteristics such as high strength, wear resistance, and high temperature resistance.

[0003] During the production process of metal cylinder liners, dimensional inspection is required. The problem with the above-mentioned technology is that, in the existing technology, the dimensional inspection of metal cylinder liners is generally carried out by measuring rulers. However, the measuring rulers are too simple and cannot measure the length and diameter of the metal cylinder liners at the same time, thus reducing the practicality of the measuring rulers. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a tooling for measuring the dimensions of metal cylinder liners that can overcome or at least partially solve the above problems.

[0005] This utility model is implemented as follows: a tooling for measuring the size of a metal cylinder liner, comprising a base, a support leg, and a placement groove, characterized in that: the bottom of the base is fixedly installed on the top of the support leg; the bottom of the placement groove is fixedly installed on the middle of the top of the base; a diameter measuring mechanism is installed on the rear side of the top of the base; a support mechanism is installed on the front side of the top of the base; a moving mechanism is installed on the front side of the top of the base; a rotating mechanism is installed on the right side of the top of the base; and a baffle is installed on the rear side of the placement groove, the bottom of which is fixedly installed on the rear side of the top of the base.

[0006] To facilitate the measurement of the diameter of the metal cylinder liner, preferably, the diameter measuring mechanism includes a support frame, a moving rod, and a measuring plate. The bottom of the support frame is fixedly installed on the rear side of the top of the base, the surface of the moving rod is movably installed in the middle of the support frame, the top of the measuring plate is fixedly installed on the bottom of the moving rod, a scale line is installed on the front side of the moving rod, and a tension spring is installed on the top of the measuring plate. By moving the moving rod, the measuring plate is moved to the surface of the metal cylinder liner, and the diameter of the metal cylinder liner can be viewed through the scale line.

[0007] To facilitate support of the moving mechanism, preferably, the support mechanism includes a first support plate, a second support plate, and a connecting rod. The bottom of the first support plate is fixedly installed on the top of the base, and the bottom of the second support plate is fixedly installed on the top of the base. The second support plate is located behind the first support plate, and the rear side of the first support plate and the front side of the second support plate are fixedly connected by the connecting rod. The moving mechanism can be mounted on the connecting rod, which is then mounted on the first and second support plates, thereby supporting the moving mechanism.

[0008] To facilitate the fixing of the metal cylinder liner, preferably, the moving mechanism includes a vertical plate, a moving frame, and a lead screw. The bottom of the vertical plate is fixedly installed on the top of the base, the surface of the lead screw is movably installed on the middle of the vertical plate, the middle of the left side of the moving frame is movably installed on the surface of the connecting rod, and the middle of the right side of the moving frame is movably installed on the surface of the lead screw. The surface of the lead screw and the middle of the right side of the moving frame are connected by threads. By rotating the lead screw, the lead screw drives the moving frame to move through the threaded connection, and the moving frame fixes the metal cylinder liner.

[0009] To improve the rotation of the lead screw, preferably, the rotation mechanism includes a servo motor, a gear, and a toothed belt. The rear side of the left gear is fixedly installed on the front side of the lead screw, and the rear side of the right gear is fixedly installed on the output end of the servo motor. The left gear and the right gear are movably connected by a toothed belt. The bottom of the servo motor is fixedly installed on the top of the base. The servo motor can rotate, and the servo motor drives the left gear to rotate, which in turn drives the lead screw to rotate.

[0010] To facilitate the measurement of the length of the metal cylinder liner, preferably, a scale is installed on the left side of the top of the base, and the bottom left side of the movable frame is movably installed on the top of the scale. The length of the metal cylinder liner can be measured by the cooperation of the movable frame and the scale.

[0011] To facilitate the movement of the measuring plate, preferably, one end of the tension spring is fixedly installed on the top of the measuring plate, and the other end of the tension spring is fixedly installed on the top of the inner cavity of the support frame. The measuring plate can be mounted on the tension spring, and the tension spring can be mounted on the support frame, thereby driving the measuring plate to move.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, by setting up a base, support legs, a placement slot, a diameter measuring mechanism, a support mechanism, a moving mechanism, a rotating mechanism, and a baffle, first places the metal cylinder liner on the placement slot, then opens the rotating mechanism, causing the servo motor to rotate. The servo motor drives the left gear to rotate, which in turn drives the lead screw to rotate. The lead screw, through a threaded connection, moves the moving frame onto the metal cylinder liner. By cooperating with the scale, the length of the metal cylinder liner can be viewed. Then, moving the moving rod causes the vertical plate to move the measuring plate onto the metal cylinder liner, where the diameter of the metal cylinder liner can be viewed through the scale lines. This invention solves the problem in existing technologies where metal cylinder liners are typically measured using a measuring ruler, but the ruler is too simple and cannot simultaneously measure the length and diameter of the metal cylinder liner, thus reducing its practicality.
