Description

A kind of pick-up unit of multinomial morpheme error

Technical field

The utility model relates to the technical field that component of machine detects, specifically a kind of device that detects multinomial morpheme error.

Background technology

The quality of engineering goods and component of machine is determined by manufacturing technology level.In the numerous factors that influence engineering goods and component of machine quality, the detection means imperfection is one of principal element.

For middle-size and small-size machining factory, owing to be subjected to the restriction of objective condition such as product specification is many, little, circulating capital is few in batches, so lack some special-purpose measurement instruments.Detect for some simple length, width, diameter equidimension, conventional measurement instrument just can be competent at.But when requiring multinomial morpheme error detected, it is powerless just to seem.

Even big machinery processing enterprise is when carrying out the detection of morpheme error, in the face of problems such as the restriction of specially-used measuring instrument service condition, high acquisition expenses and equipment are idle for a long time, also very awkward sometimes.

Summary of the invention

The purpose of this utility model is the pick-up unit that is to provide a kind of multinomial morpheme error, it can satisfy the detection needs of machining enterprise to the form and position tolerance project of component of machine routine, have simultaneously simple in structure, be convenient to make, characteristics that detection that precision can satisfy general parts requires.

The technical solution of the utility model is to achieve these goals: the pick-up unit of this multinomial morpheme error, it mainly comprises pedestal, sliding seat, balance weight iron, handwheel, driving wheel, engaged wheel, it is characterized in that: sliding seat links to each other with balance weight iron, handwheel is connected with sliding seat by driving wheel, engaged wheel, flexible nylon stay cord, lever indicator is installed on the sliding seat, sliding seat can slide up and down along column, and pedestal can move on platform.

The beneficial effects of the utility model are: according to the requirement of test item, the utility model has different use-patterns.During detection of vertical degree error,, sliding seat is moved up and down, utilize the lever indicator that is installed on the sliding seat to detect by rotating handwheel; When detecting other project, the position of locking sliding seat, translation base, make the lever indicator gauge outfit contact the outline element of detected component of machine, thereby detect the morpheme error of detected mechanical component, the utility model in use can satisfy the conventional sense accuracy requirement of general parts, and is not high to operator's technical requirement, can use at processing site, detect stable performance, repeatability and reproduction shape are good, simple in structure, easy to manufacture, low cost of manufacture.

Fig. 2 is a kind of A-A cut-open view of pick-up unit of multinomial morpheme error;

Fig. 3 is that a kind of B of pick-up unit of multinomial morpheme error is to view.

In above-mentioned accompanying drawing, 1. installing plate, 2. nylon withdrawal line, 3. balance weight iron, 4. copper sheathing, 5. sliding seat, 6. lock-screw, 7. lever indicator, 8. column, 9. dog screw, 10. pedestal, 11. handwheel, 12. bearing assemblies, 13. driving wheels, 14. engaged wheels, 15. lock-screws.

Embodiment

Fig. 1 is the disclosed embodiment of the utility model, this device comprises a pedestal 10, column 8 and engaged wheel 14 are installed on the pedestal 10, pedestal 10, engaged wheel 14 form this device main body with upper mounting plate 1,

column

8,4 columns 8 are installed between pedestal 10 and the installing plate 1, engaged wheel 14 is installed on the pedestal 10, handwheel 11, bearing assembly 12 and driving wheel 13 are installed above the installing plate 1, sliding seat 5 is installed on the column 8 by copper sheathing 4.Driving wheel 13 is connected with engaged wheel 14, balance weight iron 3 and sliding seat 5 by flexible nylon stay cord 2.One end of sliding seat 5 has dog screw 9 other ends that lever indicator 7 is installed, lock-screw 15 can adjust lever indicator angle, balance weight iron 3 is connected with sliding seat 5 by flexible nylon withdrawal line 2.

During detection, at first the detection according to tested component of machine requires this device is placed on the detection platform, and tested component of machine is placed on the platform correct position; Adjust the angle (level or vertical) of lever indicator 7 then according to the specific requirement of test item, guarantee the contact contact measured workpiece of lever indicator 7, and fastening with lock-screw 15.

The following concrete enforcement that specifies this device according to different test items.

When measuring vertical degree error, the orientation of adjusting lever indicator 7 is a level orientation, guarantees that contact contacts tested position; Then rotate handwheel 11, sliding seat 5 is moved up and down along column 8.Because sliding seat 5 is connected by nylon rope 2 with balance weight iron 3, and between sliding seat 5 and the column 8 copper sheathing 3 has been installed, thereby guarantee that lever indicator 7 operates steadily, can freely be parked in any position simultaneously; The numerical value change of the gauge outfit demonstration of the lever indicator 7 on the slide 10 is exactly the error of perpendicularity of measured workpiece to platform plane at this moment.

When measurement plane degree, the depth of parallelism, straightness error, the angle of adjusting lever indicator 7 is 90 °, guarantees lever indicator contact contact measured workpiece, and is fastening with lock-screw 15, and tightens the dog screw 9 on the sliding seat; With hand translation base 10, the numerical value change of lever indicator 7 demonstrations this moment is exactly flatness, the depth of parallelism, the straightness error of measured workpiece to platform plane.

Circle is beated when measuring, when total run-out, right alignment, cylindricity, deviation from circular from, specific requirement according to test item, measured workpiece is placed on the aiding supports such as V-block, axle, the angle of adjusting lever indicator 7 is 90 °, guarantee the contact contact measured workpiece of lever indicator 7, fastening with lock-screw 15, and tighten dog screw 9 on the sliding seat; The rotation measured workpiece, the numerical value change of lever indicator 7 demonstrations this moment is exactly the error of measured workpiece to reference center's line or reference plane.
