Abstract
The utility model discloses a measuring instrument for the axial force of a machine tool center, and is used for solving the problems of inaccurate measurement, easy leakage of hydraulic oil and impossibility of being connected with a modern digital control system which exist in the measurement for the axial force of the existing machine tool. The utility model comprises a tailstock, a center, a measuring element and an end cover, wherein the tail of the tailstock is fixed with the end cover, and the center is arranged in the tailstock; the tail of the center is provided with the measuring element, and the measuring element is a weighting sensor; a sensor bracket is arranged outside the weighting sensor, and the weighting sensor is connected with a measuring meter arranged outside the tailstock. The utility model uses the weighting sensor, the bracket and the corresponding measuring meter, and can carry out accurate measurement on the size of the stress of a machine tool center; by using the method to measure the pressure of the center, the installation and the maintenance are both very easy, stable and reliable, and the utility model completely satisfies the requirement of controlling signals of a modern digital control machine tool; the utility model is suitable for various machine tools which have certain requirements for axial forces of processed work pieces.
Description
Technical field:
The utility model relates to a kind of device that the top stressed size of lathe is measured.
Background technology:
When the long workpiece of machine tooling, need the other end of the top fixation workpiece of tailstock tool, the great power in top top can be calculated according to the situation of workpiece.Power top in the practical operation need be measured.
Domestic each machine tool plant generally adopts oil-filled copper chamber matrix gaging pressure at present.Method is: copper chamber matrix is installed in top afterbody, and the top axial force that is subjected to, the hydraulic oil in the matrix of copper chamber also is subjected to same pressure, measures top power indirectly by tensimeter again.This method exist measure inaccurate, hydraulic oil easy to leak, can't with problems such as modern digital control system is connected.
Summary of the invention
The purpose of this utility model provides a kind of lathe tail spindle to force measuring instrument, and the measurement that the top axial force of existing lathe exists in measuring is inaccurate to solve, hydraulic oil easy to leak, the problem that can't be connected with modern digital control system.
The utility model comprises tailstock, top, measuring sensor and end cap, and the afterbody of tailstock is fixed with end cap, is provided with top, top afterbody in the tailstock and is provided with measuring sensor; Described measuring sensor is a LOAD CELLS, and the measurement instrument outside LOAD CELLS is outside equipped with sensor stand, LOAD CELLS and is located at tailstock links to each other.
The utility model utilizes LOAD CELLS and support and corresponding measurement instrument, and the stressed size that lathe is top is measured accurately.Measure top pressure with this form, installation and maintenance all are very easy to, and be stable, reliable, and satisfy the control signal requirement of modern numerically-controlled machine fully.It is applicable to various axial forces to the workpiece to be machined lathe that has certain requirements.
The utility model is described in further detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model lathe tail spindle is to force measuring instrument, comprises tailstock 1, top 2, measuring sensor and end cap 5, and the afterbody of tailstock 1 is fixed with end cap 5, is provided with move forward and backward top 2 in the tailstock 1 within it, and top 2 afterbody is provided with measuring sensor; Measuring sensor is a LOAD CELLS 3, and the measurement instrument 6 outside LOAD CELLS 3 is outside equipped with sensor stand 4, LOAD CELLS 3 and is located at tailstock 1 links to each other.LOAD CELLS 3 can be 1-6, is preferably 1-3.
As shown in the figure, top 2 of tailstock tool can be at the intrinsic displacement of tailstock 1 after being subjected to thrust, make the stressed and variation that produces electric signal of LOAD CELLS 3 in the sensor stand 4, the electric signal that LOAD CELLS 3 records is transformed to reading and control signal by measurement instrument 6, for showing and control is used.Sensor stand 4 should guarantee that LOAD CELLS 3 has sufficient intensity, and is stressed in the right direction, satisfies the requirement of the maximum top axial force of lathe.LOAD CELLS 3 all can have been bought on market with measurement instrument 6.
