Abstract

The utility model aims to provide a clamping system with a flexible loading function, which comprises a servo motor, a coupler, a key on a servo motor shaft, a key on a screw, a bearing, a frame, the screw, balls, a nut, a spring, a spring guide sleeve, a pressure sensor and the like. The servo motor drives the screw to rotate through the coupler, the spring is extruded by a ball-screw-nut pair to generate pre-tightening force, and the force is transferred to a workpiece by the aid of the spring guide sleeve. The pressure sensor mounted on the spring guide sleeve is capable of measuring pressure and feeding the measured pressure back to the servo motor. The servo motor is adjusted to reach a preset pressure value finally by a program, so that the workpiece is clamped. The flexible clamping system is simple in mechanism and outstanding in clamping effect.

Description

Flexible Fixturing mechanism

Technical field

This patent relates to a kind of flexible clamp system that loads, and is particularly useful for the clamping of surperficial coated workpiece.

Background technology

Frictional wear experiment for surperficial texture; The experiment test specimen often has coating; If adopt conventional rigidity clamp system to clamp; The unevenness of power will be reflected on the border, causes on the border skewness of acting force even uncertain, and this brings very big difficulty for regularity of analytical test result.More serious words possibly cause breaking or coming off of test specimen top layer coating material, directly test findings are caused very big interference.The characteristics of coating material have determined the traditional clamp device of very difficult usefulness to study the rubbing wear character of surperficial texture, and this just needs to adopt new test unit, and the boundary force in guaranteeing to test is uniform.Adopt this mechanism can realize that axial flexibility loads, test specimen pressure in the process of friction texturizing and destruction remains unchanged.This is to the effective high-quality crucial meaning that has of warranty test result.

Summary of the invention

The purpose of the utility model is to disclose a kind of clamp system with flexible loading effect.The utility model is made up of the key on servomotor, shaft coupling, the servo motor shaft, 12 parts such as key, bearing, frame, leading screw, ball, nut, spring, spring guide, pressure transducer on the leading screw.Servomotor is connected through the key on the servo motor shaft with shaft coupling, and shaft coupling is connected through the key on the leading screw with leading screw; During work, servomotor drives the leading screw rotation through shaft coupling, and leading screw, ball and nut constitute ball guide screw nat and form relative motion, and the nut extrusion spring produces pretightning force, spring be pressed on the spring guide and the most at last power be delivered on the test specimen; Pressure transducer is installed on the spring guide institute's measuring pressure is fed back to servomotor; Leading screw one end is connected to frame through bearing, and secondly servomotor also is fixed on the frame, finally fixes Flexible Fixturing mechanism.Nut extrusion spring and then afterburning to spring guide wherein is that the rotation of the ball guide screw nat through nut and leading screw obtains.Its mechanism is simple, clamping is remarkably productive.

Description of drawings

Fig. 1 is the utility model Flexible Fixturing mechanism structure figure

Among the figure: the 1-servomotor; 2-1-shaft coupling left-half; The 2-2-upper stud; Double-screw bolt under the 2-3-; 2-4-shaft coupling right half part; Key on the 3-servo motor shaft; Key on the 4-leading screw; The 5-bearing; The 6-frame; The 7-leading screw; The 8-ball; The 9-nut; The 10-spring; The 11-spring guide; The 12-pressure transducer; The 13-test specimen.

Embodiment

Below in conjunction with accompanying drawing the utility model Flexible Fixturing mechanism is further specified:

A kind of Flexible Fixturing as shown in Figure 1 mechanism mainly is made up of the key 3 on servomotor 1, shaft coupling 2, the servo motor shaft, the key 4 on the leading screw, bearing 5, frame 6, leading screw 7, ball 8, nut 9, spring 10, spring guide 11, pressure transducer 12.Servomotor 1 is fixed on the frame 6 with leading screw 7, and servomotor 1 links together through shaft coupling 2 with leading screw 7.Leading screw 7, ball 8 constitute ball guide screw nat with nut 9; When servomotor 1 drives leading screw 7 rotations; Relative motion takes place with leading screw 7 in nut 9; Nut 9 extrusion springs 10, spring 10 passes to spring guide 11 with power again, and spring guide 11 passes to test specimen 13 with pretightning force at last and realizes the function that clamps.Pressure transducer 12 is installed on the spring guide 11; Pressure transducer 12 can be measured the pretightning force that is carried on the test specimen 13; Pressure transducer 12 is with result back servomotor 1, and servomotor 1 carries out self adjustment according to feedback result, thereby makes the pretightning force that is carried on the test specimen 13 reach setting value; Realization loads the flexibility of test specimen 13, and then has guaranteed the accuracy of his-and-hers watches plane texture friction-wear test.
