Description

Centering instrument for machine tool

Technical Field

The utility model relates to the technical field of centering equipment, in particular to a centering instrument for a machine tool.

Background

When the rocker arm old machine tool is used, a workpiece is placed on a workbench, then a tool bit on the vertical shaft of the machine tool is controlled to be aligned with the workpiece on the workbench, drilling or cutting machining is carried out, and in order to align the tool bit with the workbench, the workbench on the guide rail is required to be moved to be centered before machining, so that the workpiece clamped at the center of the workbench and the tool bit are located on the same vertical line. Most of the existing centering modes adopt visual centering, are easy to detect inaccuracy, or a laser alignment instrument is arranged on a vertical shaft, but when the tool bit works, larger vibration can be generated, and the laser alignment instrument is easy to misplace for a long time.

Disclosure of Invention

In view of the above, it is necessary to provide a centering instrument for a machine tool.

The utility model provides a centering instrument for lathe, includes centering instrument body, anchor clamps and measuring bar, anchor clamps include base and riser, the L type is constituteed with the riser perpendicular connection to the base, the base is the type of falling U, the base inboard is provided with two rows of relative gyro wheels, the measuring bar set up on the base up end, and with the direction of rolling of gyro wheel is unanimous, centering instrument body installs on the riser.

Preferably, the vertical plate is provided with a steel column, and the centering instrument body is inserted on the steel column.

The utility model has the advantages that: utilize the base card on the guide rail of lathe, gyro wheel and guide rail limit laminating to use the workstation butt on measuring beam and the lathe, when displacement workstation is constructed through the lead screw, the centering appearance body is along the synchronous displacement of guide rail, is used for centering with the centering appearance transmitter of fixing on the lathe, and the survey is more accurate, and very convenient to use.

Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below.

It will be understood that when an element is referred to as being "fixed" or "disposed" on another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only and are not meant to be the only embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-2, a centering instrument for a machine tool comprises a centering instrument body 1, a clamp 2 and a measuring rod 3, wherein the clamp 2 comprises a base 21 and a vertical plate 22, the base 21 and the vertical plate 22 are vertically connected to form an L-shaped structure, the base 21 is of an inverted U-shaped structure, two rows of opposite rollers 211 are arranged on the inner side of the base 21, the measuring rod 3 is arranged on the upper end surface of the base 21, the extending direction of the measuring rod 3 is consistent with the rolling direction of the rollers 211, and the centering instrument body 1 is arranged on the vertical plate 22. Specifically, during the use, a centering instrument transmitter is installed on the mesa of lathe (not shown in the figure), and centering instrument body 1 in this application passes through anchor clamps 2 to be installed on the guide rail (not shown in the figure) of lathe to utilize measuring rod 3 to be connected with the workstation on the lathe, it can be known that the workstation on the lathe is movable mounting on the guide rail, and utilizes lead screw or electric putter etc. to drive the workstation and make the work piece of centre gripping on the workstation move to the tool bit below of lathe vertical scroll along the guide rail back and forth displacement, carry out drilling or cutting operation. When the workbench is displaced along the guide rail, the clamp 2 connected with the workbench can be synchronously displaced along the guide rail, the rollers 211 are arranged on the base 21 at the bottom of the clamp 2, the two rows of rollers 211 are arranged side by side and are respectively arranged on two sides of the guide rail and are abutted to the outer sides of the guide rail, and when the clamp 2 is displaced, the rollers 211 and the outer side walls of the guide rail are in rolling friction, so that the friction coefficient between the base 21 and the guide rail is greatly reduced, and the displacement is smoother. Optionally, the centering instrument body 1 fixed on the vertical plate 22 may be a transmitter or a receiver, and correspondingly, the centering instrument body 1 fixed on the machine table surface is a receiver or a transmitter, when the fixture 2 drives the centering instrument body 1 to be positioned on the same straight line with the centering instrument body fixed on the machine table surface, a signal can be sent, and a user can know that the workbench has moved to a specified position, namely, the position right below the vertical shaft tool bit can be locked, and the operation is started. When the edge of the workpiece is required to be machined or eccentric machining is carried out, the measuring rod 3 with different lengths is only required to be replaced according to the eccentric distance, and the measuring rod is very convenient to use.

As shown in fig. 1-2, the vertical plate 22 is provided with a steel column 221, the centering instrument body 1 is inserted into the steel column 221, the steel column 221 is provided with threads, and the centering instrument body 1 can be locked on the steel column 221 by using nuts, so that the centering instrument is convenient to assemble and disassemble.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model.
