Detailed Description

In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.

Example 1:

referring to fig. 1 to 5, the present embodiment provides an assembling and positioning device for a carbon fiber truss for an airship, including: a chord support bracket group for supporting the chord 1 from the bottom of the chord 1, and a chord clamp plate group for limiting from the side upper part of the chord 1 to clamp the chord 1 in the chord support bracket group.

In detail, the chord brace set comprises a transverse support rod 101 and a longitudinal support rod 102 which are vertically connected, a pair of first support grooves 104 for supporting the chord 1 are symmetrically arranged on the side end face of the transverse support rod 101 connected with the longitudinal support rod 102, and a second support groove 103 for supporting the chord 1 is arranged at the top end of the longitudinal support rod 102. It should be noted here that the specific carbon fiber truss structural member includes three chords 1 having cross sections suitable for forming a triangular structure, taking an equilateral triangular structure as an example, here, a pair of first supporting grooves 104 respectively correspond to two bottom corners of the equilateral triangle, while a second supporting groove 103 corresponds to a top corner of the equilateral triangle, and further, taking the bottom side of the equilateral triangular structure as a horizontal line, the notches of the pair of first supporting grooves 104 and the second supporting groove 103 face upward from the horizontal line.

Taking the example that the cross section of three chords 1 of an alternative carbon fiber truss structural member is an equilateral triangle structure, the longitudinal support rod 102 in this case is fixedly connected with the middle position of the transverse support rod 101, and a pair of first support grooves 104 on the transverse support rod 101 are connected with the vertical distance from the longitudinal support rod 102; the portions of the pair of catch plates 111 that are respectively hinged to the lateral support bars 101 are at the same vertical distance from the longitudinal support bars 102.

In an alternative embodiment, the first support groove 104 and the second support groove 103 each include a pair of L-shaped flaps 106, the pair of L-shaped flaps 106 being disposed opposite each other and forming a receiving section 107 for receiving the chord 1 between the pair of L-shaped flaps 106; the openings of the first and second card slots 112, 114 are each adapted to face the chord 1 received in the receiving section 107. In consideration of the variety of standard specifications of the chord 1, in order to improve the adaptability of the first supporting groove 104 and the second supporting groove 103 of the embodiment to chords 1 with different standard specifications, a pair of L-shaped folding plates 106 of the first supporting groove 104 can be fastened and positioned with the transverse supporting rod 101 through screws 108, and a plurality of threaded holes 109 suitable for being connected with the L-shaped folding plates 106 are formed in the transverse supporting rod 101, so that when the L-shaped folding plates 106 are selected to be correspondingly connected with different threaded holes 109 of the transverse supporting rod 101, the sizes of accommodating sections 107 formed between the pair of L-shaped folding plates 106 are different, and the adaptability to chords 1 with different standard specifications is realized.

The chord card board group comprises a pair of card boards 111 respectively hinged with the transverse supporting rod 101, the pair of card boards 111 are suitable for forming a structure with a triangular cross section together with the transverse supporting rod, the pair of card boards 111 can be hinged with the end part of the transverse supporting rod 101 near the width direction, so that the card boards 111 can adjust the difference of the included angle formed relative to the transverse supporting rod 101, at the moment, the larger the included angle formed by the card boards 111 relative to the transverse supporting rod 101 corresponds to the trend that the card boards 111 gradually open relative to the chord 1 placed in the first supporting groove 104 or the second supporting groove 103, and conversely, the smaller the included angle formed by the card boards 111 relative to the transverse supporting rod 101 corresponds to the trend that the card boards 111 gradually close relative to the chord 1 placed in the first supporting groove 104 or the second supporting groove 103. In addition, for the hinge joint of the clamping plate 111 and the transverse supporting rod 101 in the embodiment, after the chord 1 is placed in the first supporting groove 104 of the transverse supporting rod 101, so that the clamping plate 111 is clamped with the chord 1, the side wall of the clamping plate 111 abuts against the side wall of the first supporting groove 104, or a slight gap exists between the side wall of the clamping plate 111 and the side wall of the first supporting groove 104; after the chord 1 is placed in the second supporting groove 103 of the longitudinal supporting rod 102, and the clamping plate 111 is clamped with the chord 1, the side wall of the clamping plate 111 abuts against the side wall of the second supporting groove 103, or a slight gap exists between the side wall of the clamping plate 111 and the side wall of the second supporting groove 103.

Specifically, the clamping plates 111 clamp the chord 1 by opening a first clamping groove 112 corresponding to the first supporting groove 104 and a second clamping groove 114 corresponding to the second supporting groove 103 on opposite side end faces of the pair of clamping plates 111. After the chord 1 is placed in the first supporting groove 104, the first engaging groove 112 of the engaging plate 111 engages the chord 1 from the side upper side of the chord 1 (for "side upper", it is to be additionally described that the side and upper side of the part are included), and similarly, when the chord 1 is placed in the second supporting groove 103, the second engaging groove 114 of the engaging plate 111 engages the chord 1 from the side upper side of the chord 1. For the first and second engaging grooves 112 and 114, the size of the notch is larger than the outer diameter of the chord 1 to be clamped, so that the clamping plates 111 have good adaptability to chords 1 of different standards, because the clamping limiting effect on the chord 1 is generated by pressing down the chord 1 above the side of the chord 1 for the first and second engaging grooves 112 and 114.

It should be noted that, for the first support groove 104 and the second support groove 103 of the present embodiment, the accommodation section 107 formed by the pair of L-shaped flaps 106 constituting the first support groove 104 and the second support groove 103 mainly accommodates the chord 1, so that, in order to facilitate the chord 1 to be placed into the first support groove 104 or the second support groove 103 and to be transferred out of the first support groove 104 and the second support groove 103, the pair of L-shaped flaps 106 of either the first support groove 104 or the second support groove 103 do not form an absolute clamp for the chord 1, and mainly play a role of supporting the chord 1 from the bottom of the chord 1.

In consideration of the adjustment of the hinge angle of the clamping plate 111 relative to the transverse support rod 101, according to the prefabricated chords 1 with different standards, the effective clamping force of the clamping plate 111 relative to the chords 1 is different, so as to facilitate the classified accurate control of the chords 1 with different standards and avoid errors in the manual adjustment process, the assembly positioning device for the carbon fiber truss for the airship of the embodiment further comprises a driving mechanism of the clamping plate 111, wherein the driving mechanism is used for driving the first clamping groove 112 and the second clamping groove 114 of the clamping plate 111 to control the opening and closing angles of the clamping plate 111 relative to the chords 1.

In more detail, the catch plate 111 driving mechanism includes a first push rod 113 hingedly connected to the catch plate 111, and a first electric cylinder 115 connected to the push rod to drive the push rod to move linearly. The linear motion of the first pusher arm 113 is driven by the first electric cylinder 115 to cause the first pusher arm 113 to push the catch plate 111 at an angle that becomes larger or smaller with respect to the lateral support bar 101, that is, to correspondingly achieve an opening or closing tendency with respect to the chord 1 placed in the first support groove 104 of the lateral support bar 101.

In addition, considering that the stroke of the first pushing rod 113 is different for the compression of the chords 1 of different standards, in order to accurately control the stroke of the first pushing rod 113, the driving mechanism of the catch plate 111 of the present embodiment further includes a displacement sensor 117 provided outside the first electric cylinder 115 or inside the first electric cylinder 115 and adapted to collect displacement data of the first pushing rod 113. The displacement data of the first push rod 113 is accurately grasped through the displacement sensor 117, so that the pushing acting force of the first push rod 113 on the clamping plate 111 is accurately grasped, namely the included angle of the clamping plate 111 relative to the transverse supporting rod 101 is accurately controlled under the action of the first push rod 113, and the opening and closing states of the clamping plate 111 on the chord 1 placed in the first supporting groove 104 of the transverse supporting rod 101 are accurately and correspondingly adjusted and controlled through the adjustment and control of the included angle of the clamping plate 111 relative to the transverse supporting rod 101.

Wherein, when the first electric cylinder 115 is internally provided with the displacement sensor 117 suitable for acquiring the displacement data of the first push rod 113, the electric cylinder with the built-in displacement sensor 117 and the precise ball screw disclosed in the patent with the publication number of CN208369386U can be selected, the electric cylinder comprises a motor, a coupler, a shell, a high-precision screw rod, a high-precision screw nut, a force output shaft, a guide rod, a linear guide rail, the displacement sensor 117, a bidirectional thrust bearing and a paired angular contact bearing, the force output shaft is connected with the top of the guide rod, when the guide rod performs linear motion, because the fixed end of the displacement sensor 117 is connected with the casing of the electric cylinder, the motion end is connected with the screw nut, thus the displacement of the screw nut in the linear direction can be acquired and monitored by the displacement sensor 117 in the whole course, and then the displacement sensor 117 transmits the displacement to a controller or an acquisition system to realize, in this process, the displacement of the spindle nut is equivalent to the displacement of the guide bar, and the displacement of the guide bar is equivalent to the displacement of the output shaft. Wherein the output shaft is equivalent to the first push lever 113 in the present embodiment.

And when the displacement sensor 117 suitable for acquiring displacement data of the first push rod 113 is arranged outside the first electric cylinder 115, at this time, the displacement sensor 117 may be arranged at an end of the first electric cylinder 115 away from the first push rod 113, and the displacement sensor 117 may be sleeved on the first push rod 113 in the first electric cylinder 11, and the displacement sensor at this time adopts the linear displacement sensor 117, and when the first electric cylinder 115 drives the first push rod 113 to make linear motion, the displacement sensor 117 is used for recording displacement data of the first push rod 113.

It should be noted that, 5 meters of carbon fiber trusses, 10 meters of carbon fiber trusses, and even longer carbon fiber trusses are all formed by assembling a plurality of standard 1 meter long carbon fiber truss structural members, and in the assembling process, the 1 meter long carbon fiber truss structural members are sequentially connected, the assembling and positioning device of the carbon fiber truss for the airship of this embodiment mainly functions to clamp and position the fiber truss structural member located at the front position in the sequentially connected 1 meter long carbon fibers, so that the carbon fiber truss structural member located at the rear position and 1 meter long carbon fiber truss structural member located at the front position can be accurately assembled, for example, for the 5 meters of carbon fiber truss, the chord member 1 located at the first meter carbon fiber truss structural member in the 5 meters of carbon fiber truss is firstly clamped and positioned, then the chord member 1 of the second meter carbon fiber truss structural member is connected with the chord member 1 of the first meter carbon fiber truss structural member, at this time, when the chord member 1 of the third carbon fiber truss structural member is connected with the chord member 1 of the second carbon fiber truss structural member, due to the clamping and limiting effect of the assembly and positioning device of the carbon fiber truss for the airship on the chord member 1 of the first carbon fiber truss structural member, the assembly precision between the chord member 1 of the third carbon fiber truss structural member and the chord member 1 of the second carbon fiber truss structural member can be effectively ensured under the condition that the chord member 1 of the first carbon fiber truss structural member is clamped and limited when the chord member 1 of the third carbon fiber truss structural member is connected with the chord member 1 of the second carbon fiber truss structural member, but when the chord member 1 of the fourth carbon fiber truss structural member is assembled with the chord member 1 of the third carbon fiber truss structural member, under the better condition, the assembly and positioning device of the carbon fiber truss for the airship needs to move to the chord member 1 of the second carbon fiber truss structural member or the chord member 1 of the third carbon fiber truss structural member The assembly precision between chord member 1 of the fourth meter carbon fiber truss structure and chord member 1 of the third meter carbon fiber truss structure can be effectively guaranteed during chord member 1, and the analogy is repeated, along with the change of the whole length of the carbon fiber truss, the assembly positioning device of the carbon fiber truss for the airship also needs to update chord member 1 of the carbon fiber truss structure which is clamped and limited tightly, so that the precision in the assembly process of the whole carbon fiber truss can be effectively guaranteed. Of course, there is an alternative embodiment, where a plurality of assembling and positioning devices of carbon fiber trusses for airship are used, for example, for a 5 m carbon fiber truss, 2 assembling and positioning devices of carbon fiber trusses for airship may be used, and these two assembling and positioning devices of carbon fiber trusses for airship may be respectively clamped and limited with the chord 1 of the first carbon fiber truss structural member for airship and clamped and limited with the chord 1 of the third carbon fiber truss structural member for airship, and for a 10 m carbon fiber truss, 4 assembling and positioning devices of carbon fiber trusses for airship may be used.

Based on the consideration to the above problem, the assembly positioning device of carbon fiber truss for airship of this embodiment only adopts when one just needs to realize that the chord member 1 of the carbon fiber truss structure that corresponds different positions through removing presss from both sides tight spacing, or when adopting the assembly positioning device of a plurality of carbon fiber truss for airship, also need to transfer the position between the assembly positioning device of a plurality of carbon fiber truss for airship, and artificial removal mode or artificial calibration mode, may cause the skew of the position of the assembly positioning device of carbon fiber truss for airship, or need constantly to adjust the degree of accuracy of the cooperation position between the assembly positioning device of carbon fiber truss for airship and chord member 1, and is time-consuming and laborious, still can't effectively guarantee the degree of accuracy of manual operation. Therefore, it is necessary to design a structure capable of mechanically adjusting the position of the assembly positioning device of the carbon fiber truss for the airship relative to the chord 1, and in this process, it is also necessary to consider that the chord 1 of the carbon fiber truss is not the straight chord 1 but the chord 1 in a certain arc shape as the whole carbon fiber truss for the airship. In view of the above problems, the assembling and positioning device for the carbon fiber truss for the airship of the embodiment further comprises a pair of supporting legs 118 arranged at the bottom ends of the transverse supporting rods 101, sliding wheels 119 arranged at the ends of the supporting legs 118, which are far away from the transverse supporting rods 101, and a supporting base 3 matched with the sliding wheels 119; the end surface of the supporting base 3 facing the sliding wheel 119 is provided with an arc-shaped track 121 for matching with the sliding wheel 119, and it should be particularly noted that, for the arc-shaped track 121 here, the arc-shaped opening of the arc-shaped track 121 faces the sliding wheel 119, that is, taking the supporting base 3 with a rectangular structure as an example, the arc-shaped track 121 is in a concave shape from both ends of the supporting base 3 in the width direction to the central position of the supporting base 3, and such a concave tendency is matched with the arc-shaped chord 1.

In an alternative embodiment, at least one of the sliding wheels 119 of the pair of supporting legs 118 is connected to a power assembly for driving the sliding wheel 119 to slide along the arc-shaped track 121; and a locking plate 122 suitable for stopping the sliding wheel 119 from sliding relative to the arc-shaped track 121 is also arranged on the supporting leg 118, and here, the sliding wheels 119 corresponding to the pair of supporting legs 118 are respectively connected with a power assembly. The locking plate 122 is hinged to the supporting leg 118, so that the sliding wheel 119 can be stopped by adjusting the angle between the locking plate 122 and the supporting leg 118, when the locking plate 122 is not in contact with the sliding wheel 119, the locking plate 122 does not have a stopping effect on the movement of the sliding wheel 119, and when the locking plate 122 is in contact with the sliding wheel 119, the locking plate 122 has a stopping effect, namely the rotation of the sliding wheel 119. Certainly, the power for the sliding wheels 119 to slide along the arc-shaped rails 121 may also be power for manually pushing the assembling and positioning device of the carbon fiber truss for the airship to move, the sliding track of the sliding wheels 119 is limited by the arc-shaped rails 121, and the accuracy of the position of the assembling and positioning device of the carbon fiber truss for the airship in the moving process of the arc-shaped rails 121 can be effectively ensured only by manually providing a driving force.

In this embodiment, taking an alternative power assembly structure as an example, the power assembly includes a power shaft 123 fixedly connected to the sliding wheel 119, a rotating wheel 124 fixedly connected to the power shaft 123, a driving wheel 126 connected to the rotating wheel 124 through a timing belt 125, and a servo motor 128 connected to the drive wheel 126 to drive the drive wheel 126 to rotate, in the process, when the servo motor 128 drives the transmission wheel 126 to rotate, the rotating wheel 124 also rotates under the action of the timing belt 125, the rotating wheel 124 realizes the rotation of the sliding wheel 119 through the synchronization action of the power shaft 123, and when the sliding wheel 119 rotates, the support legs 118 can move along the arc-shaped rails 121, when the support legs 118 move along the arc-shaped rails 121, the carbon fiber truss assembly positioning device for the airship moves along the arc-shaped rails 121, therefore, the assembly positioning device of the carbon fiber truss for the airship can be adjusted to clamp and limit the chord members 1 of the carbon fiber truss structural members at different positions.

Example 2:

on the basis of the assembling and positioning device of the carbon fiber truss for the airship of embodiment 1, the assembling and positioning device of the carbon fiber truss for the airship further includes an abutting mechanism which is arranged on the clamping plate 111 and close to the second clamping groove 114 and is suitable for abutting against the chord 1 from the side lower part of the chord 1.

The pair of locking plates 111 respectively correspond to the pair of first supporting grooves 104 on the lateral supporting rod 101 to realize the locking and limiting of the chord 1 in the first supporting groove 104, while the pair of locking plates 111 simultaneously realize the locking and limiting of the second supporting groove 103 with the second supporting groove 103 on the longitudinal supporting rod 102. In the case of the first support groove 104, after the chord 1 is placed in the first support groove 104 and the first engaging groove 112 of the engaging plate 111 is engaged with the chord 1, in the process of engaging the engaging plate 111 with the side upper side of the chord 1, not only the downward pressing on the side upper side of the chord 1 is achieved, but also the pressure on the side of the chord 1 by the engaging plate 111 causes the chord 1 to abut against the L-shaped flap 106 on the side close to the longitudinal support rod 102 of the pair of L-shaped flaps 106 of the first support groove 104, so that the chord 1 placed in the first support groove 104 is opposed to the lateral support rod 101 between the pair of L-shaped flaps 106, the L-shaped flap 106 on the side close to the longitudinal support rod 102, and the engaging plate 111 together form a pressing limit for the bottom, both sides and top of the chord 1. While, for the second support groove 103, the pair of catch plates 111 are pressed simultaneously against the chord 1 placed in the second support groove 103 and are urged from both sides of the chord 1, and the range of urging of the catch plates 111 to the chord 1 in this case is also above the side of the chord 1. However, in the case of the chord 1 placed in the second support groove 103, the chord 1 cannot be clamped by one of the pair of L-shaped flaps 106 of the first support groove 104 in combination with the clip 111, as in the case of the chord 1 in the first support groove 104, but the chord 1 is limited in the accommodating section 107 formed by the pair of L-shaped flaps 106 by the pair of clips 111, so that the chord 1 cannot abut against any of the pair of L-shaped flaps 106, in such a case, because the side walls of the pair of clips 111 abut against the side walls of the second support groove 103 under the forces above the two sides respectively formed by the pair of clips 111 on the chord 1, or a slight gap exists between the side walls of the clip 111 and the side walls of the second support groove 103, there may be a case that the chord 1 is pressed over the two sides formed by the pair of clips 111 on the chord 1 to cause the chord 1 to tilt around the fulcrum of the second support groove 103 in the lateral direction of the support groove 101, such a tilting condition is defined herein as "down-tilting".

In view of the above-described concern about the tilting of the chord 1 in the second supporting groove 103, the assembling and positioning device for a carbon fiber truss for an airship according to the present embodiment is designed with an abutting mechanism adapted to abut against the chord 1 from the side lower side of the chord 1, provided on the snap plate 111 and near the second snap groove 114. The abutting mechanism mainly has the function that when the pair of clamping plates 111 press the chord 1 from the upper sides of the two sides of the chord 1 placed in the second supporting groove 103, the top supporting function of the chord 1 is realized from the bottom of the chord 1, and the situation that the chord 1 is warped downwards under the pressing function of the pair of clamping plates 111 is avoided.

In detail, the abutting mechanism of the present embodiment includes an abutting block 131 adapted to abut against a lateral lower portion of the chord 1, a second pushing rod 132 connected to the abutting block 131 to drive the abutting block 131 to move away from and toward the chord 1, and a second electric cylinder 133 connected to the second pushing rod 132 to drive the second pushing rod 132 to move linearly; wherein the abutting block 131 is slidably coupled with a slide rail 135 fixed on the clamping plate 111. Under the action of the second electric cylinder 133, the second pushing rod 132 generates a pushing force to the abutting block 131, so that the abutting block 131 slides along the slide rail 135 to gradually move from a position far away from the chord 1 to a position close to the chord 1, and finally, a contact and abutting effect to the chord 1 is achieved. Here, the abutting blocks 131 respectively provided on the pair of clamping plates 111 may form a V-shaped support structure for the lower portions of both sides of the chord 1.

Considering that the jacking forces to be applied by the chords 1 of different standards and specifications are different, therefore, considering that the jacking force of the second pushing rod 132 to the chord 1 is convenient to accurately grasp, in the embodiment, the pressure sensor 136 is sleeved on the second pushing rod 132, and the load applied to the chord 1 is acquired by the pressure sensor 136 (here, the second electric cylinder 133 converts the rotary motion of the servo motor 128 into the linear reciprocating motion of the second electric cylinder 133 through the combined action of the servo motor 128 and the ball screw, the speed of the linear reciprocating motion is controlled through the rotating speed of the servo motor 128, the stroke is determined through the number of rotating turns of the servo motor 128, the current pressure is fed back to the controller, and the controller automatically corrects data through a program to achieve the assembling purpose of accurate positioning).
