The state detection assembly 1 is used for obtaining elastic state change data of the sofa cloth through the change of stress of the state detection assembly 1 when the linear driving assembly 4 drives the movable clamping assembly 2 to move close to or away from the fixed clamping assembly 3.
Further, in the present invention, there is provided an embodiment of the linear driving assembly 4, wherein the linear driving assembly 4 includes linear seats 41 disposed at both sides of the clamping position, guide slots 42 along the length direction of the linear seats 41 are disposed on the side surfaces of the linear seats 41 facing the clamping position, driving screw rods 43 are mounted in the guide slots 42, and nut pairs 44 are cooperatively mounted on the driving screw rods 43. The end of the movable clamping assembly 2 passes through the guiding slot 42 to be connected with the nut pair 44, and the nut pair 44 drives the movable clamping assembly 2 to move along the length direction of the guiding slot 42 under the driving of the driving screw 43.
The fixed clamping assembly 3 is disposed at the end of the linear seat 41 remote from the movable clamping assembly 2.
The purpose of the movable clamping assembly 2 in the present invention is to realize one-side clamping of a sofa cloth, and there are many structures that can be realized in the prior art, but in order to more clearly illustrate the working principle of the present invention, a specific embodiment of the movable clamping assembly 2 and the fixed clamping assembly 3 is provided, specifically:
the movable clamping assembly 2 comprises a beam frame 5, the beam frame 5 and the fixed clamping assembly 3 are respectively connected with a first clamping piece 6 through the state detection assembly 1, and the first clamping piece 6 is used for clamping sofa cloth.
Further, in order to change the clamping position of the first clamping piece 6 on the beam frame 5 while changing the unidirectional traction elasticity of the sofa fabric, the change can be synchronous (the first clamping pieces 6 in the fixed clamping assembly 3 are positioned at the same height) or asynchronous (the positions of the first clamping pieces 6 on the movable clamping assembly 2 are adjustable), the side wall of the beam frame 5 of the movable clamping assembly 2 is provided with a height adjusting groove 7 along the width direction of the beam frame 5, a sliding block 8 is arranged in the height adjusting groove 7, the first clamping pieces 6 are connected to the sliding block 8 through the state detecting assembly 1, a height adjusting piece 9 is arranged at the top of the height adjusting groove 7, one end of the height adjusting piece 9 is connected to the sliding block 8, and the height adjusting piece 9 is used for adjusting the position of the sliding block 8 in the height adjusting groove 7. The state detection assembly 1 is in spherical hinge connection with the sliding block 8, so that the angle change of the state detection assembly 1 relative to the sofa cloth after the height of the sliding block 8 is changed can be realized.
In the invention, in order to realize the elastic change detection of the sofa cloth in a state that a plurality of directions are fixed in one direction and synchronously stretched, the side edge of the sofa cloth is required to be provided with a clamping structure and can synchronously move along with the driving screw 43, and the position change control of a plurality of clamping points is also included in the moving process, so that the aim of multi-angle multi-direction clamping is fulfilled. And thus also includes a plurality of side clamping assemblies 10, the plurality of side clamping assemblies 10 being mounted on the linear seat 41 through the width-adjustable guide grooves 11 provided in the length direction of the linear seat 41.
The side clamping assembly 10 comprises a base 101 in threaded connection with the driving screw 43, a movable seat 102 is arranged on the base 101, the movable seat 102 is connected with a second clamping piece 103 through the state detection assembly 1, and the second clamping piece 103 clamps the side edge of the sofa cloth. A rolling wheel 104 is provided on top of the movable seat 102, and the rolling wheel 104 is installed in the width-adjustable guide groove 11.
Wherein, the driving screw 43 drives the base 101 to move along the length direction of the driving screw 43, so that the rolling wheel 104 moves along the length direction of the width-adjustable guide groove 11.
Because in the clamping process, if the second clamping piece 103 is directly and rigidly connected to the side edge of the sofa, when the clamping point of the side edge of the sofa is fixed, the first fixed clamping point will generate a force in the opposite direction to the movable clamping component 2, so that the clamping point is easy to break, and thus an error of elastic detection is easy to generate, and therefore, the force applied to the sofa after the position of a certain clamping point is fixed is adapted and buffered. The movable seat 102 and the base 101 can be relatively displaced without disengagement, that is, the movable seat 102 and the base 101 can be connected by a spring in the longitudinal direction (the longitudinal direction of the driving screw 43).
The diameters of the rolling wheels 104 of the plurality of side clamping assemblies 10 are set to be equal difference in the length direction of the width-adjustable guide groove 11, so that the aim is to sequentially fix the clamping points of the plurality of second clamping pieces 103 on the side edge of sofa cloth and sequentially fix the positions of the moving rolling wheels 104 of the movable clamping assembly 2 driven by the following driving screw 43 under the limitation of the width-adjustable guide groove 11.
It is of course necessary here for the final width of the width-adjustable guide groove 11 to be adapted to the diameter variations of the plurality of rolling wheels 104.
In the above, the linear motion relationship between the width-adjustable guide groove 11 and the rolling wheel 104 is the length direction of the width-adjustable guide groove 11, and in a practical structure, the upper and lower parts of the width-adjustable guide groove 11 need to be capable of supporting the upper and lower surfaces of the rolling wheel 104, and the rolling wheel 104 is not separated from the width-adjustable guide groove 11 all the time.
The width-adjustable guide groove 11 according to the present invention specifically includes a rectangular groove 16 disposed on the upper surface of a straight seat 41, a groove body 15 is disposed on both sides of the rectangular groove 16 in the length direction, one end of the groove body 15 is hinged to the rectangular groove 16, and the other end of the groove body 15 can be movably rotated, which of course has the main purpose of changing the shape formed between the two groove bodies 15 between a rectangular shape and an isosceles trapezoid shape, and of course has the purpose of controlling the positions of a plurality of rolling wheels 104 having diameters disposed in an equi-differential manner.
For example, the structure of the width-adjustable guide groove 11 is rectangular, so that the width and the diameter of the rolling wheel with the largest diameter are the same, at this time, the rolling wheel with the largest diameter is clamped by the width-adjustable guide groove 11 and is fixed, while the rolling wheels 104 with other diameters are driven by the driving screw 43, and the connection unit of the base 101 and the movable seat 102 is driven to move along the width-adjustable guide groove 11, so that a plurality of rolling wheels 104 are arranged at equal intervals in an ideal condition.
When the structure of the width-adjustable guide groove 11 is trapezoid, in an initial state, the top width of the width-adjustable guide groove 11 is smaller than the diameter of the smallest rolling wheel 104, the bottom width of the width-adjustable guide groove 11 is larger than the diameter of the largest rolling wheel 104, the rolling wheels 104 which are in an equal difference under the driving of the driving screw 43 are sequentially clamped at the same position as the width of the width-adjustable guide groove 11, so that force application traction sofa cloth is carried out on the side edges, and the state of the sofa cloth when the side edges are subjected to force traction is simulated.
In the experimental process, the invention needs parameter control of multi-angle extension (embodied in the above description) and single-direction extension (namely, only the extension direction under the clamping action of the movable clamping component 2 driven by the driving screw 43) of the comprehensive sofa cloth, so that the side clamping component 10 can selectively move synchronously or asynchronously with the movable clamping component 2, deformation of unidirectional clamping is realized by sofa cloth during synchronous movement, and elasticity detection under multi-direction multi-angle clamping is realized during asynchronous movement.
The multi-angle extension of the sofa cloth simulates the elastic change condition of the large-area multi-angle stress of the sofa cloth in the actual process.
For this purpose, the bottom of the base 101 is provided with a fitting groove 105 having a U-shaped longitudinal section, and the curved bottom of the fitting groove 105 is provided with a screw surface for fitting the drive screw 43. The rolling wheel 104 is rotatably mounted on the movable seat 102 by a clutch screw 106, and the clutch screw 106 is used for adjusting the overall height of the connection between the base 101 and the movable seat 102 so that the threaded surface is disconnected from the driving screw 43. The clutch screw 106 comprises a rotating sleeve 107 for fixedly connecting the rolling wheel 104, and an adjusting screw 108 is axially and threadedly connected with the inner part of the rotating sleeve 107. Wherein the rolling wheel 104 is rotatably sleeved outside the rotating sleeve 107.
Of course, in combination with the above multi-directional multi-angle clamping, the present invention can also selectively perform the arrangement of the side clamping points of the sofa fabric and the elasticity test of the sofa fabric in this case by performing the operation of the clutch screws 106 of the side clamping assemblies 10.
That is, the rolling wheel 104 is always limited to the width-adjustable guide groove 11 by the restriction of the width-adjustable guide groove 11, and at this time, the adjusting screw 108 is manually rotated to adjust the overall height of the connection between the adjusting base 101 and the movable base 102. The top of the adjusting screw 108 protrudes out of the adjustable width guide groove 11.
Further, in order to perform the sofa fabric elasticity test of coupling and multidirectional stress variation, mainly because the stress of the sofa fabric is uneven and irregular when the sofa fabric finally becomes the sofa surface, the horizontal elasticity of the sofa fabric represents the extensibility test of the sofa fabric, so that the coupling vertical direction test process is used for satisfying the elastic coupling stress variation when the sofa fabric is subjected to downward pressure when the sofa fabric is horizontally extended, the surface force application detection assembly 17 is arranged at the upper part of the clamping position, and the surface force application detection assembly 17 is used for applying pressure to the upper surface of the sofa fabric in the clamping position and detecting pressure variation data, and of course, the first clamping piece 6 correspondingly generates tension variation in the process, so that comprehensive judgment of sofa fabric elasticity of various data is formed.
That is, the main purpose of the surface-applied-force detecting assembly 17 is to perform surface application and detect elastic changes when the sofa cloth is horizontally extended or not, and various technical structures can be implemented in the prior art, and to more clearly describe the working mode of the present invention, the present invention specifically provides an embodiment of the surface-applied-force detecting assembly 17:
the pressure sensing contact head 13 is vertically arranged in the middle of the upper part of the transverse bracket 12 positioned at the clamping position.
The pressure sensing contact 13 is mounted on the transverse bracket 12 through a linear displacement adjusting seat 14, the linear displacement adjusting seat 14 is used for adjusting the position of the pressure sensing contact 13 in the longitudinal direction, the pressure applied to the sofa cloth is changed, the linear displacement adjusting seat 14 can be specifically any one of a linear motor, a hydraulic cylinder and a pneumatic cylinder or a steering engine, and the purpose of the linear displacement adjusting seat is to achieve longitudinal displacement of the pressure sensing contact 13, and the linear displacement adjusting seat is better achieved in the prior art.
Of course, when the moment of the sofa cloth needs to be considered to be the parameter of the moment of the force elastic change or the parameter of the moment of the force elastic change, the linear displacement adjustment seat 14 needs to have the capability of losing the driving force instantaneously and being fully subjected to the reaction force of the sofa cloth, so the linear displacement adjustment seat 14 is preferably a linear motor. Of course, when the sofa cloth surface elasticity when the sofa cloth is overlapped and horizontally extends is changed (the contact between the pressure sensing contact head 13 and the sofa cloth is not stressed, and the contact is stressed), the opposite acting force of the sofa cloth to the pressure sensing contact head 13 needs to be synchronously detected.
Further illustratively, the status detecting assembly 1 of the present invention includes, but is not limited to, a tension sensor, a pressure sensor, and an angle sensor. That is, the stress body generated after the first clamping member 6 and the second clamping member 103 are contacted with the sofa cloth is the state detecting assembly 1.
The above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
