Description

Tool ruler for mechanical design

technical field

The utility model relates to the field of mechanical tools, in particular to a tool ruler for mechanical design.

Background technique

At present, in my country's machining industry, verticality error measurement for product quality control, workpiece measurement, and tooling equipment adjustment, in addition to using large-scale detection instruments such as three-coordinates, is basically measured by using a square ruler with a feeler gauge. The perpendicularity error is approximated by the feeler gauge, and the square ruler has high requirements on the accuracy of the reference plane and the measured surface, which is very inconvenient. Especially in the process of coordinate size measurement of the workpiece, it is necessary to adjust the perpendicularity between the workpiece and the reference plane, and it is necessary to have an accurate verticality value, which requires a tool ruler for mechanical design that can be directly read. In order to measure accurately, some enterprises have introduced advanced measuring instruments such as three coordinates, but the cost is relatively expensive, and some special workpieces cannot be measured, which is inconvenient to use.

Utility model content

In order to solve the above problems, the utility model provides a tool ruler for mechanical design, which is accurate in measurement and easy to use, and is suitable for the tool ruler for mechanical design of some special workpieces.

In order to achieve the above object, the technical scheme that the utility model takes is:

A tool ruler for mechanical design, including a base and a column, the column is vertically movably connected to the base, one end of the column is connected to a hydraulic cylinder, the hydraulic cylinder is embedded in the base, and one end of the hydraulic cylinder is provided with a telescopic rod , the column is connected with the telescopic rod through threads, a suction cup is provided at the bottom of the base, a slidable sliding sleeve is set on the column, and the sliding sleeve is connected with a horizontally placed indicator through a connecting device , the connecting device includes a watch frame, fastening bolts, fastening sleeves and screws, the watch frame to which it belongs is a hollow cubic structure, and the front and rear sides of the watch frame are provided with pull-out plates, and one end of the watch frame is connected to the The sliding sleeves are fastened together, and the other end fixes the indicator horizontally through the fastening sleeve and the internal fastening bolt.

Preferably, the column is provided with a receiving groove.

Preferably, an LED lamp is connected to the storage tank through a metal hose.

The utility model uses two readings of the indicator to record the verticality result, which is very convenient to use. The indicator can use a dial indicator or a dial indicator to achieve different accuracy, and the measurement is more accurate; it has strong practicability, as long as it can be placed on the base This mechanical design can be used anywhere to measure with a tool ruler, which solves the problem that some special workpieces cannot be measured, and has stronger applicability. The height of the column can be adjusted according to needs, and the measured object can be supported by the drawing plate , more convenient to use, and can be used in dark environments.

Detailed ways

In order to make the purpose and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Referring to Fig. 1, the present specific embodiment adopts the following technical solutions: a tool ruler for mechanical design, including a base 1 and a column 2, and the column 2 is vertically movably connected to the base 1, and one end of the column 1 is connected with a hydraulic cylinder 12, and the The hydraulic cylinder 12 is embedded in the base 1, and one end of the hydraulic cylinder 12 is provided with a telescopic rod, and the column 1 is connected with the telescopic rod through threads, and the bottom end of the base 1 is provided with a suction cup 11, and the column 2 is covered with a slidable sliding sleeve 3, and the sliding sleeve 3 is connected with the horizontally placed indicator 8 through a connecting device. The connecting device includes a table frame 5, a fastening bolt 6, a fastening sleeve 7 and screws 9. The table frame 5 to which it belongs is a hollow cubic structure, and the front and rear sides of the table frame 5 are provided with pull-out plates 4. One end of the table frame 5 is fastened together with the sliding sleeve 3 through a screw 9, and the other end is fastened by a The fixed sleeve 7 and the internal fastening bolt 6 fix the indicator 8 horizontally.

The column 2 is provided with a receiving groove 10 .

An LED lamp is connected to the storage tank 10 through a metal hose.

Wherein, a storage battery is provided in the LED lamp, a control switch is provided on the LED lamp, and several clips are provided on the column for holding the book for recording, and the storage slot 10 can also be used for It is practical to place tools such as pens.

This specific implementation uses two readings of the indicator to record the verticality results, which is very convenient to use. The indicator can use a dial indicator or a dial indicator to achieve different accuracy, and the measurement is more accurate; it is practical, as long as it can be placed on the base This mechanical design can be used anywhere to measure with a tool ruler, which solves the problem that some special workpieces cannot be measured, and has stronger applicability.
