Abstract
The utility model provides a shaft work piece outer surface machining error detection teaching aid. A sliding table cushion block, a ball screw sliding table mechanism, a center cushion block, a center mechanism and a motor are installed on a plastic machine base. A belt wheel of the center mechanism is connected with a belt wheel of the motor through a belt for transmission. The ball screw sliding table mechanism is provided with a screw sliding table center. A ball screw cross sliding table is installed on the plastic machine base. Another motor is connected with a ball screw of the ball screw cross sliding table through a coupler. A KTR miniature linear self-recovery sensor is installed on the ball screw cross sliding table. An electric appliance control box is installed on the machine base. A handle is arranged at one end of the screw sliding table center. Through teaching demonstration of geometric sense errors, the teaching aid enables students to understand the basic concepts of many geometric sense tolerances. The teaching aid can show the measurement result of a single work piece directly and allow the students to see the result clearly, thereby deepening the understanding for various tolerance items.
Description
Technical field
The utility model is that a kind of shaft-like workpiece outside surface mismachining tolerance detects teaching aid, belongs to teaching appliance field.
Background technology
Existing shaft-like workpiece outside surface mismachining tolerance detects teaching aid and is mostly the pointer utensils such as dial gauge, clock gauge, although precision is also comparatively accurate, but operate relative complex, and its maximum drawback is to react by the reading of pointer the mismachining tolerance of outside surface, surveyed data cannot be generated to figure, do not see the fluctuation range of practical work piece outside surface mismachining tolerance, and then cannot allow student have a visual in image understanding for the knowledge of relevant tolerance.
Summary of the invention
The purpose of this utility model is, solves above-mentioned existing existing problem, and a kind of simple to operate and electromechanical integration feature that has is provided, and for the detection of error and the shaft-like workpiece outside surface mismachining tolerance of geometric sense tolerance classroom instruction, detects teaching aid.
The utility model is achieved in that on slide unit cushion block, ball-screw slipway mechanism installation plastics support, top cushion block, tip mechanism, the first motor are installed on plastics support; The belt wheel of tip mechanism is by the belt wheel connection for transmission of belt and motor; Clip is arranged on tip mechanism, and it is top that ball-screw slipway mechanism is provided with leading screw slide unit; Ball-screw cross slid platform is installed on plastics support, and the second motor is connected with the ball-screw of ball-screw cross slid platform by shaft coupling, and gyration is converted into rectilinear motion, and the miniature straight line self-recovering type of KTR installation of sensors is on ball-screw cross slid platform.The 3rd motor is connected with ball-screw cross slid platform by shaft coupling; Electric appliance control box is installed on plastics support, and handle is arranged on the top end of leading screw slide unit.
The utility model has the advantages that, one of them motor drives tail spindle to rotate by belt wheel in the mode with transmission, clamping like this workpiece just can rotate together with top, second motor is connected with ball-screw by shaft coupling, the gyration of motor is converted into rectilinear motion, so just can realize the radial feed of sensor, realize sensor and contact with workpiece and safe card engaging workpiece.Sensor can be realized the axially-movable of sensor under the drive of axial leading screw.When just can comprise some geometric sense errors such as linearity, total run-out in measurement, can realize axial measurement.Its control section is single-chip microcomputer, by mcu programming, can realize the designated movement of each motor, pass in addition by the measured real time data of sensor and can be recorded in real time on VB interface by host computer technology, by VB, programme and data can be plotted to figure in addition.Student just can understand the testing result of geometric sense error more visual in imagely like this, understands better the concept about geometric sense tolerance.
By the teaching demonstration for geometric sense error, not only can allow student recognize the key concept of a lot of geometric sense tolerances, more can reflect intuitively the measurement result of single workpiece, make student very clear, deepen the understanding to all kinds of tolerance projects.The thought of electromechanical integration is fully demonstrated on classroom, and this teaching aid can be used for electromechanical integration classroom simultaneously, also will produce better effect.

Embodiment
Below in conjunction with accompanying drawing, describe in detail: as shown in the figure, slide unit cushion block 5, ball-screw slipway mechanism 4 are installed on plastics support 1, top cushion block 8, tip mechanism 9, the first motor 13 are installed on plastics support 1; The belt wheel 10 of tip mechanism 9 is belt wheel 12 connection for transmissions with motor 13 by belt 11; Clip 7 is arranged on tip mechanism 9, and ball-screw slipway mechanism 4 is provided with leading screw slide unit top 6; Ball-screw cross slid platform 2 is installed on plastics support 1, the second motor 14 is connected with the ball-screw of ball-screw cross slid platform 2 by shaft coupling 15, gyration is converted into rectilinear motion, so just can realize the radial feed of sensor, realize sensor and contact with workpiece and safe card engaging workpiece.The miniature straight line self-recovering type of KTR sensor 3 is arranged on ball-screw cross slid platform 2, can make sensor 3 at the uniform velocity and move by intended trajectory, can Measurement accuracy.The 3rd motor 17 is connected with ball-screw cross slid platform 2 by shaft coupling 16; Electric appliance control box 18 is installed on plastics support 1, and handle 19 is arranged on the end of leading screw slide unit top 6.
Leading screw slide unit top 6 with tip mechanism 9 on same straight line and with axial cross slide unit lead screw shaft line parallel, testee is by top and clip 7 location clampings, leading screw slide unit top 6 can be adjusted axial distance by handle 19, so that card engaging workpiece, the belt wheel 10 of opposite side tip mechanism 9 is connected and is able to uniform rotation with the belt wheel 12 of motor 13, clamping like this workpiece just can rotate together with top, and it is more accurate to make to measure.
During operation, electric appliance control box 18 is handled the second motor 14 and is driven ball-screw cross slid platform 2 uniform motion to assigned address, make sensor on it can Measurement accuracy to tested part error change value, handling the first motor 13 also moves with uniform velocity by the drive of band wheel mechanism is top, handling the 3rd motor 17 can be to sensor radial feed, thereby the realization of electromechanical integration detects, finally by sensor, realize that linearity, circle are beated, the measurement of total run-out equal error.
