Abstract
Description
Technical Field
[0001] The utility model relates to a tool for detecting a hard rail column and a main spindle box axis of a vertical machining center, belonging to the technical field of machining center detection. Background Art
[0002] The hard rail column and spindle box of the VMC1300B vertical machining center are both one of the five key components of the machine tool. After the hard rail column and the spindle box are combined, the positive and lateral accuracy of the spindle axis are both within 0.01mm.
[0003] Currently, this data cannot be directly measured at the assembly site. Instead, the spindle box must be mounted on a column, and a 6T pneumatic cylinder installed beneath it. This cylinder pulls the rear end of the spindle box to set it in motion. A check rod is installed at the front end of the spindle box, and a bracket is placed outside the spindle box, with a micrometer indicator mounted on top. While the spindle box moves, one person controls the cylinder while another manually tightens the side of the spindle box while looking up at the micrometer indicator. While this technically required data can be obtained, this operation is extremely laborious and time-consuming, significantly impacting on-site production efficiency. Summary of the Invention
[0004] The technical problem to be solved by the utility model is to provide a vertical machining center hard rail column and spindle box axis detection tooling, which can move in accordance with the column guide rail, replacing the original hard rail column movement, thereby improving the detection efficiency.
[0005] To solve the above problems, the specific technical solution of the utility model is as follows: a vertical machining center hard rail column and spindle box axis detection tooling, including a connecting rod, a base and a rolling limit device; wherein the base is provided with limiting edges on the front and rear of the bottom surface, the inner surface of the left limiting edge is the base surface, and is in contact with one side of the hard rail for limiting; the right limiting edge is connected to the rolling limit device, and the rolling limit device is in rolling cooperation with the other side of the hard rail; a vertical connecting rod is connected to the top of the base, and a micrometer used for detection is connected to the connecting rod through the gauge rod.
[0006] The rolling limit device includes a core shaft, a bearing, a vertical bolt and a transverse bolt; two parallel long holes are provided on the upper surface of the base near the right limiting edge, and the length direction of the long holes is perpendicular to the moving direction of the base; two threaded holes are provided on the right limiting edge, and their center lines are located in the same vertical plane as the center lines of the corresponding long holes; the upper and lower interference fit bearings of the core shaft, the bottom of the vertical bolt passes through the long hole and is threadedly connected to the top of the core shaft; a socket is provided on the side end of the core shaft, and after the transverse bolt is threadedly connected to the threaded hole, the inner end is inserted into the socket.
[0007] The lower surface of the base is provided with a plastic surface, and the plastic surface is seated on the upper surface of the hard rail.
[0008] The vertical machining center hard rail column and spindle box axis detection tooling of the present application adopts the above-mentioned structure, which not only ensures that the base and the hard rail are completely positioned and improves the detection accuracy, but also the base volume and gravity are much smaller than the weight of the hard rail column, making it more convenient to move, thereby improving the detection efficiency.
