Description of the embodiments
For the purpose of making apparent the objects, technical solutions and advantages of the present invention, the present invention will be further described in detail with reference to the following examples and the accompanying drawings, wherein the exemplary embodiments of the present invention and the descriptions thereof are for illustrating the present invention only and are not to be construed as limiting the present invention.
As shown in fig. 1-3, the present embodiment provides an adjustable self-adaptive clamp for grasping material bags, which comprises a connecting component 1, a clamping component 2 connected to the lower side of the connecting component 1, and a clamping jaw component 3 connected to the lower side of the clamping component 2; the clamping jaw assembly 3 comprises a mounting seat 4, a driving assembly 5 arranged on the mounting seat 4 and a plurality of clamping jaws 6 with adjustable intervals arranged on the driving assembly 5, wherein the clamping jaws 6 can synchronously move under the driving of the driving assembly 5 to puncture a material bag so as to grab or withdraw the material bag to realize separation; at least one or both ends of the jaws 6 may be disengaged from the drive assembly 5 in a driving relationship to release the gripping or separating action of the bag.
The connecting component 1 can be connected with external equipment such as a multi-axis robot so as to drive the whole self-adaptive clamp to act, the clamping jaw component 3 can be clamped with the clamping component 2 through the mounting seat 4 so as to be firmly connected to the connecting component 1, when the self-adaptive clamp is applied, the distance between the clamping jaws 6 can be adjusted according to the length of a material bag, the clamping jaws 6 can be used for uniformly grabbing the material bag, in addition, the redundant clamping jaws 6 can be separated from the material bag with small specification when the material bag is grabbed through the design of the clamping jaws 6 which can be separated from the driving component 5, further, the material bag can be prevented from acting when the material bag forms a stack to puncture other material bags, after the clamping jaws 6 are adjusted, the clamping jaws 6 can be driven to synchronously move through the driving component 5 so as to realize grabbing the material bag or withdraw the material bag after unloading is completed, and the actions of the self-adaptive clamp on grabbing the material bag and automatic unloading the material bag can be realized.
According to the embodiment, based on the structure, the clamping jaw 6 with adjustable intervals can adapt to the grabbing of material bags with different length specifications, and when grabbing material bags with shorter sizes, the clamping jaw located at one end or two end parts of the clamping jaws can be separated from a driving relation with the driving component, so that the clamping jaw is not involved in the actions of the rest clamping jaw 6, the rest material bags can be staggered to avoid the material bags from being grabbed or damaged, particularly, the material bags with orderly stacking can be grabbed by one bag, accurate material grabbing is realized, the stability after material grabbing is ensured, meanwhile, the material bags are grabbed by the mode that the clamping jaw 6 pierces the material bags, the material bags can be firmly supported by the whole body of the material bags, meanwhile, the subsequent material bags are also facilitated to be broken, the leakage area of the broken bags is increased, and the material residues are reduced.
Because the material bag is placed, the material bag cannot be determined to be in a state of expected requirements, the situation that the material bag is up-and-down fluctuant or has different actual thickness can possibly occur, at the moment, if the material bag cannot be adapted according to the form of a specific material bag during grabbing, the material bag cannot be uniformly supported after grabbing due to improper grabbing positions, and further the transportation stability of the material bag after grabbing and the integrity of the material bag are affected due to overlarge local gravity.
Based on this, the connection assembly 1 and the clamping assembly 2 are connected in a swingable manner by means of a universal joint connection 7. Through universal joint connection structure 7, coupling assembling 1 and clamping assembly 2 are after connecting, can carry out the swing of a small margin based on universal joint connection structure 7, and then the two can carry out adaptive relative position adjustment, when clamping jaw 6 needs snatch the material bag, can move down clamping jaw subassembly 3 until contact with the material bag, laminate through going towards with the general of material bag for clamping jaw subassembly 3 can better match the state of putting of material bag, and then make clamping jaw 6 can more adapt to putting of material bag when snatching, improve the degree of uniformity that snatchs, the material bag atress is even after snatching, the transportation is steady, also can not damage because of the local atress is too big.
When specifically using, the universal joint connection structure 7 includes two universal joint connectors 8 of the same structure, and universal joint connector 8 all is provided with cardan shaft 9, and one of them universal joint connector 8 is connected with coupling assembling 1, and remaining one universal joint connector 8 is connected with clamping assembly 2, and two universal joint connectors 8 are connected through being crisscross matched cardan shaft 9 formation, and then form universal joint connection structure 7. Specifically, the universal joint connector 8 comprises bottom plate and two curb plates, and two curb plate intervals set up relatively, and cardan shaft 9 then connects between two curb plates, and during the connection, the space between cardan shaft 9 and the bottom plate then carries out cardan shaft 9 installation and rotation as the installation and the rotation space of another cardan shaft 9 to after connecting cardan joint connector 8 each other can exist the universal regulation of a small circle after connecting, in order to adapt to putting of material bag.
When the material bag is grabbed and transported, stability of the material bag needs to be kept as much as possible, the material bag can shake due to movement in the subsequent transportation process, and after the universal joint connecting structure 7 is added, the stability of the material bag after grabbing can be ensured, but the stability of the material bag during transportation after grabbing can not be well ensured, so that the material bag is easy to shake along with the swinging of the clamping assembly 2, and grabbing of the material bag or leakage of materials can not be ensured even after shaking.
For this reason, as shown in fig. 3-8, the adaptive clamp of the present embodiment further includes a swing restraint assembly; the swing restraint assembly comprises a rotation restraint piece arranged on the connecting assembly 1 and a fixed restraint piece 10 arranged on the clamping assembly 2; the rotation restraint comprises a restraint power source 11 which is connected to the connecting component 1 in a swinging way, a rotating arm 12 which is connected with the power end of the restraint power source 11 in a rotating way, a driven shaft 13 which is fixedly connected with the rotating arm 12 and is connected to the connecting component 1 in a rotating way, and a restraint body 14 which is fixed on the driven shaft 13; the restraint power source 11 can drive the driven shaft 13 and the restraint body 14 to synchronously rotate through the rotating arm 12, so as to drive the restraint body 14 to rotate so as to be opposite to or staggered with the fixed restraint member 10 to form mutual blocking or unblocking.
In this swing restraint subassembly, after restraint power supply 11 starts, it can drive driven shaft 13 through the rotation arm 12 and rotate, and then drive the synchronous rotation of restraint body 14 on driven shaft 13, and when restraint body 14 rotates, it can rotate to blockking each other with fixed restraint 10, and then through the mutual blocking of fixed restraint 10 and restraint body 14, the relative motion of connecting assembly 1 and clamping assembly 2 that both are connected respectively is blocked, and then eliminate universal adjustment function of universal joint connection structure 7, and when needs, then accessible restraint body 14 rotates and is separated with fixed restraint 10 and unblock, and then do not influence universal adjustment function of universal joint connection structure 7 when snatching, and then realized adjustable self-adaptation anchor clamps swing restraint effect.
In specific application, in order to ensure the stability of constraint, two groups of swing constraint components are uniformly distributed on the outer side of the connecting component 1; in each set of the swing restraint assembly, two sets of the restraint body 14 and the fixed restraint 10 are correspondingly arranged. Based on this, four total fixed restraint pieces 10 set up in the coupling assembling 1 outside two by two, and then when restraint, four directions evenly receive the constraint force, also can ensure the vertical state of clamping assembly 2 when guaranteeing the restraint, ensure that the material bag can be according to snatching the steady transportation of state.
Specifically, the restraint body 14 is a cylindrical structure, and the fixed restraint 10 is vertically disposed. Further, the constraining body 14 is fixed on the driven shaft 13, and in each group of the swing constraining assemblies, two groups of constraining bodies 14 and two groups of fixed constraining pieces 10 are correspondingly arranged, and the two constraining bodies 14 are arranged on the driven shaft 13 at intervals. Further, the fixing restraint 10 is also of a cylindrical structure.
Specifically, the restraining power source 11 is a cylinder. Further, the front end of the air cylinder can be connected with the connecting component 1 through the shaft body, and then in the executing process, the air cylinder can swing around the shaft body, so that the track requirement in the moving process of the rotating arm 12 is ensured.
In order to ensure that the restraint body 14 rotates to block or unblock the fixed restraint 10, in this embodiment, when the restraint body 14 rotates to block the fixed restraint 10, a space of 0.5-1 mm is formed between the restraint body 14 and the fixed restraint 10, and even though there is a certain gap between the restraint body and the fixed restraint 10 during blocking, the connecting component 1 and the clamping component 2 still have slight shake, but can be ignored, and meanwhile, enough space is provided for separating the restraint body and the fixed restraint 10 when unblocking is needed.
Based on the above, when hindering each other, restraint body 14 rotates to fixed restraint 10 top and set up relatively, and then when coupling assembling 1 and clamping assembly 2 rock, restraint body 14 and fixed restraint 10 can hinder each other, and then prevent coupling assembling 1 and clamping assembly 2 relative swing, form the hindrance, and when restraint body 14 rotates to the fixed restraint 10 outside rather than staggering, coupling assembling 1 and clamping assembly 2 rock, restraint body 14 and fixed restraint 10 can not contact each other, and then can not influence coupling assembling 1 and clamping assembly 2 relative swing, remove the hindrance, can adapt to the material bag at this moment and put the state and carry out fine adaptation.
Because the restraint body 14 and the fixed restraint member 10 are arranged relatively to form a barrier, the contact positions of the restraint body 14 and the fixed restraint member 10 collide with each other and are stressed, wear can be formed in the past for a long time, and if the clearance between the restraint body 14 and the fixed restraint member 10 is too large due to excessive wear of the restraint body and the fixed restraint member, the restraint effect of the restraint body 14 and the fixed restraint member 10 can be influenced. The wear-resistant member 15 can be detachably connected by means of adhesion, screw connection or the like, so that the wear-resistant member is convenient to replace after subsequent wear while having a wear-resistant effect. In particular, the wear member 15 may be made of an alloy steel such as nichrome.
Furthermore, the outer side of the connecting component 1 is also connected with an annular platform 16, and the constraint power source 11 and the driven shaft 13 are both connected to the annular platform 16. The annular platform 16 is annular and is arranged outside the connecting component 1, so that stability of the connecting component 1 can be balanced, meanwhile, the annular platform can be used as an accessory and accessory mounting platform for mounting required accessories, accessories and the like, and can be also used as a supporting platform for circuits such as circuit lines and gas circuit pipes required by the self-adaptive clamp so as to meet the movement requirement of the self-adaptive clamp and external equipment.
As shown in fig. 8-11, the clamping assembly 2 comprises a connecting seat 17 connected with the connecting assembly 1, and a clamping seat 18 connected with the clamping jaw assembly 3 is arranged at the lower end of the connecting seat 17; the connecting seat 17 is also provided with a hanging piece 19, and the clamping jaw 6 can be hung on the hanging piece 19 after being separated from the driving relation with the driving assembly 5.

In particular, the hanging member 19 is a horizontal rod structure that is detachably connected. Specifically, the hanging piece 19 is a cylinder in threaded connection with the connection seat 17.
Because the specifications of the material bags are different, the weight of the materials in the material bags with certain specifications is heavier, when the clamping jaw 6 is used for grabbing, if the clamping jaw 6 is unreasonable in design or uneven in grabbing position, the materials can not be grabbed and conveyed normally,
based on this, in this embodiment, two sets of clamping seats 18 are disposed at opposite intervals at the lower end of the connecting seat 17, and each set of clamping seat 18 is connected with a set of clamping jaw assembly 3; the clamping jaws 6 of the two groups of clamping jaw assemblies 3 can be driven by the respective driving assemblies 5 to rotate relatively so as to grab the material bag between the clamping jaws or separate the material bag from the clamping jaws. According to the embodiment, two groups of oppositely arranged clamping jaw assemblies 3 are utilized to correspondingly grab the material bags at the relative positions of the material bags in the outer side directions of the material bags, so that the material bags are grabbed between the two groups of clamping jaw assemblies 3, the material bags are evenly punctured by the clamping jaws 6 at the two sides, uneven stress of the material bags can be avoided, the material bags are further torn at the puncturing positions of the clamping jaws 6, the overall postures of the material bags can be better stably grabbed and kept, the stability is improved, and the integrity and the reliability of grabbing and conveying of the material bags are further improved.
On this basis, two clamping seats 18 are arranged at intervals in each group, and each group of two clamping seats 18 are arranged opposite to the other group of two clamping seats 18 and are adjustable in horizontal position.
When the material bag is applied, the width of the material bag is also greatly changed except for the length change due to the specification change, so that the self-adaptive clamp can be more suitable for grabbing material bags with multiple specifications, the two groups of clamping seats 18 of the embodiment are designed to be oppositely arranged relative to one another, each group of the two clamping seats 18 are oppositely arranged with the two clamping seats 18 of the other group, the horizontal position of the two clamping seats is adjustable, when the clamping seats 18 are correspondingly arranged for different material bags, the corresponding clamping jaw assemblies 3 can be adjusted according to the width of the material bag, then the material bag is used for grabbing after being matched, and therefore, the material bag can be better matched with the clamping jaw assemblies 3 in length and width by combining with the adjustment of the spacing of the clamping jaws 6, and the grabbing effect is improved.
