The internally-supporting jig (100) according to the embodiment of the present application will be described in detail with reference to fig. 1 to 3 and 8. It should be noted that the following examples are only for explaining the present application and do not constitute a limitation to the present application.
In an embodiment of the present application, as shown in fig. 1 to 3, the internally-supporting jig (100) may include a supporting member (1) and an elastic member (2). The elastic part (2) can be hermetically connected with the support part (1) in a manner of covering the lower support part (11) of the support part (1), so that the elastic part (2) can expand and contract under the action of the inflation and deflation device, when the elastic part (2) can enter the object to be clamped in a contracted state, as shown in fig. 8, the elastic part which enters the inside of the object to be clamped can internally support the object to be clamped in an expanded state, so as to clamp the object to be clamped. The elastic part (2) can be hollow and provided with an opening to form a structure similar to a balloon, and the opening can be used for inflating the interior of the elastic part under the action of an inflation and deflation device so as to expand the inner wall of the elastic part outwards. In some embodiments, the largest diameter of the elastic element (2) in the contracted state is less than 9 mm. The internal supporting type clamp (100) can clamp small articles with small inner diameter. In some embodiments, the manner in which the resilient member (2) wraps around the lower support portion (11) of the support member (1) may include the lower support portion (11) being completely wrapped by the resilient member (2) and located within the hollow interior of the resilient member (2).
In order to ensure that the elastic part (2) and the support part (1) are connected in a sealing mode more firmly and are not easy to fall off from the support part (1) after the elastic part (2) is inflated, in some embodiments, the lower support part (11) can comprise a clamping connection part. Specifically, a barb structure (16) can be formed on the outer side of the lower supporting part (11) of the supporting part (1), the elastic part (2) is sleeved on the supporting part (1) in a manner of covering the barb structure (16) on the outer side of the lower supporting part (11), the surface of the barb structure (16) is completely attached to the inner surface of the elastic part (2), when the elastic part (2) is filled with gas smaller than a preset pressure threshold value, the elastic part (2) expands, and the upper surface of the barb structure (16) can generate resistance opposite to the expansion direction of the elastic part (2) so that the elastic part (2) is attached to the upper surface of the barb structure (16) more tightly, so that the elastic part (2) and the lower supporting part (11) can be in a sealing state, and the elastic part (2) does not fall off from the lower supporting part (11). In some embodiments, the preset pressure threshold may be a pressure value obtained in advance through a large number of experiments. Specifically, when the elastic part (2) is filled with gas smaller than a preset pressure threshold value, the upper surface of the barb structure (16) on the outer side of the supporting part (11) generates resistance opposite to the expansion direction of the elastic part (2), so that the elastic part (2) is not separated from the supporting part (11); when the elastic part (2) is filled with gas larger than a preset pressure threshold value, the elastic part (2) can be separated from the supporting part (11). Whether the elastic part (2) falls off is tested by filling gas with different pressure values for multiple times, and the maximum pressure value which enables the elastic part (2) not to be separated can be obtained, namely the maximum pressure value is the preset pressure threshold value. In some embodiments, the support (1) may further comprise a crimping portion (13), and the crimping portion (13) may be circumferentially fitted over the elastic member (2). In the installation state, the press-connection part (13) can press the elastic piece (2) on the lower support part (11) so as to ensure the sealing performance between the elastic piece (2) and the lower support part (11). In some embodiments, the crimp (13) may comprise a hoop, elastic rubber band, wire, flexible rope, or the like.
In some embodiments, the support (1) may further comprise an upper support (12) for connection with the outside. Specifically, the upper supporting part (12) can further comprise an air supply interface (15) used for being connected with the outside, and the air supply interface (15) is positioned at the top of the upper supporting part (12); the support piece (1) can be communicated with the air charging and discharging device through the air supply interface (15), and the air charging and discharging device can charge and discharge air into the elastic piece (2) through the air supply interface (15), so that the elastic piece (2) expands or contracts. In some embodiments, the air supply interface (15) can be a threaded connection or a snap connection, and the air supply interface (15) and the air charging and discharging device can be in threaded connection or snap connection. In some embodiments, the inflation and deflation device may be an electric inflation and deflation device, a cyclic inflation and deflation device, a gas pumping and deflation device, a gas generator or a gas storage tank, and the like.
In some embodiments, an air channel (14) may be provided within the support (1); the elastic piece (2) can be communicated with the inflation and deflation device through an air passage (14). In some embodiments, the hollow airway (14) of the support (1) may comprise a hollow cylindrical shape or a hollow polygonal prism shape. For example, a hollow triangular prism shape, a hollow quadrangular prism shape, a hollow pentagonal prism shape, or the like. The inflation and deflation device is connected with the support part (1) through the air supply interface (15), the elastic part (2) is a closed cavity which is hermetically connected with the lower support part (11), and the inflation and deflation device can inflate or deflate the elastic part (2) which is hermetically connected with the lower support part (11) through the hollow air passage (14) of the support part (1). In some embodiments, the upper support portion (12) and the lower support portion (11) of the support (1) may be integrally formed, or may be fixedly connected (e.g., welded, screwed, etc.).
In some embodiments, the elastic member (2) may be a cylindrical elastic member formed in an integrally molded manner or in a curled manner by an elastic sheet. The elastic member (2) can be formed into an airbag-like structure at the lower part of the support member (1) by sealingly connecting the cylindrical elastic member to the support member (1) in such a manner as to cover at least the lower support part (11) of the support member (1). In the installation or use state, the elastic part (2) is communicated with the air inflation and deflation device through the support part (1), so that air can be inflated into the hollow interior of the elastic part (2) to expand the elastic part (2) outwards and the air in the hollow interior of the elastic part (2) is exhausted to contract the elastic part (2). When the elastic part (2) is in an uninflated or air-extracted state, the internal-support type clamp can stretch into an object to be clamped, then the air is filled into the hollow interior of the elastic part (2) through the air filling and discharging device to enable the elastic part (2) to expand outwards until the elastic part (2) can form a proper clamping force for the object to be clamped in the object to be clamped, and the object to be clamped can be clamped from the interior; accomplish to press from both sides and get the back, the inside gas of elastic component (2) cavity of discharging makes elastic component (2) shrink, can take out in waiting to press from both sides the article with the internal stay formula anchor clamps of this application. Because the air pressure in the hollow part of the elastic part (2) can be set and adjusted according to the requirements, the force of the inner support can be adjusted, and the thin-wall or easily damaged workpieces can be safely picked up.
In some embodiments, the elastic element (2) can also be directly used as a balloon. Similarly, the air bag is connected with the support (1) in a sealing mode in a mode of covering the lower support part (11) of the support (1), in the installation or use state, the air bag is communicated with the air inflation and deflation device, so that air can be inflated into the air bag to expand the air bag outwards, the air in the air bag is exhausted to contract the elastic piece (2), and the object to be clamped can be clamped from the inside.
In some embodiments, in the expanded state, the elastic element (2) can be matched with the inner area of the clamped object in shape, so that the surface of the elastic element (2) can be better matched with the surface of the clamped object. Correspondingly, in some embodiments, the shape of the elastic part (2) can be customized and designed to be consistent with the shape of the inner accommodating space of the clamped object. In some embodiments, the outer wall of the elastic member may be textured to increase the friction between the elastic member and the object being clamped. Correspondingly, in some embodiments, the texture on the outer wall of the elastic member (2) may be designed to match the texture of the surface of the inner volume of the clamped object. In some embodiments, by designing the characteristics or texture of the surface of the elastic member (2), the direction in which the elastic member (2) expands can be restricted, and the frictional force can be increased.
In some embodiments, the material of the elastic member (2) may be a high elastic material. The elasticity of the high-elasticity material is very good, the deformation of the elastic part (2) made of the high-elasticity material can be realized by the pressure of gas, and the deformation speed of the elastic part (2) made of the high-elasticity material is high, so that the high-elasticity material is suitable for industrial application.
In some embodiments, the elastic member (2) may be made of silicone. For example, a heat-vulcanized solid silicone rubber, a fluorosilicone rubber, a liquid silicone rubber, and the like. Compared with the conventional organic elastomer, the silica gel is particularly easy to process and manufacture, can be molded, calendered and extruded under the condition of lower energy consumption, and has high production efficiency. Tensile strength refers to the force per unit of area required to cause a sample of silicone material to tear. The tensile strength range of the hot vulcanization type solid organic silica gel is between 4.0 and 12.5 MPa; the tensile strength range of the fluorosilicone gel is between 8.7 and 12.1 MPa; the tensile strength of the liquid silica gel ranges from 3.6 MPa to 11.0 MPa. Elongation refers to the "ultimate elongation at break" or the percentage increase relative to the original length when the sample breaks. Typical elongations of hot-vulcanised solid silica gels range from 90 to 1120%; the general elongation of the fluorine-silicon rubber is between 159 and 699 percent; liquid silicone gels generally have elongations between 220 and 900%. The selection of different processing methods, hardeners and temperatures can vary the elongation of the sample to a large extent.
Select for silica gel through the material with elastic component (2), when the medial surface of waiting to press from both sides the thing is complicated profile, because silica gel can produce the characteristic of very big deformation to can effectively laminate with the medial surface of target object, consequently need not carry out complicated design in advance to elastic component (2) and just can realize pressing from both sides and get. Therefore, the internal support type clamp based on the high-elasticity air bag can be suitable for objects to be clamped with complex inner contours, has strong universality, is low in production cost and high in efficiency, and is suitable for industrial scenes and life scenes.
In some embodiments, the elastic member (2) may be made of rubber. For example, natural rubber, styrene-butadiene rubber, isoprene rubber, etc. In some embodiments, the elastic element (2) may also be made of thermoplastic elastomer or elastic composite material. For example, the elastic member (2) may be a styrene-based TPE thermoplastic elastomer (e.g., SBS, SEBS, SEPS, EPDM/styrene, BR/styrene, CI-IIR/styrene, NP/styrene, etc.), an olefin-based TPE thermoplastic elastomer (e.g., a dynamically vulcanized TPO), a diene-based TPE thermoplastic elastomer, etc. For another example, POE elastic composite material or the like can be used as the elastic member (2).
In some embodiments, a reinforcing structure (21) may be provided on the outer wall (22) and/or the inner wall (23) of the elastic member (2), the outer wall (22) of the elastic member (2) being in contact with the clamped object when inflated. In some embodiments, the reinforcing structure (21) may comprise reinforcing ribs formed on the resilient member (2). In some embodiments, the reinforcing ribs are one or more of strip-shaped protrusions, wave-shaped protrusions, and saw-tooth-shaped protrusions. For example, the reinforcing rib can be an annular convex structure which extends along the circumference of the outer wall (22) of the elastic part (2) and is formed by protruding outwards along the radial direction. For another example, the reinforcing ribs may be rib structures which are arranged in the axial direction on the outer wall (22) of the elastic member (2) and are formed to protrude outward in the radial direction. In some embodiments, the number of ribs may be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 or more. When the number of the reinforcing ribs is multiple, the plurality of reinforcing ribs can be uniformly arranged on the outer wall (22) of the elastic part (2); can also be arranged on the outer wall (22) of the elastic element (2) in different ways according to requirements.
The reinforcing ribs are arranged on the outer wall (22) of the elastic part (2), so that on one hand, the friction coefficient of the surface of the elastic part (2) can be increased, the friction force with the inner side surface of the object to be clamped can be increased in the using process, and the internal support type clamp (100) can clamp the object to be clamped more stably; on the other hand, the reinforcing ribs can reinforce the elastic part (2), so that the strength, the local rigidity and the service life of the air bag are improved. In addition, the shape of the elastic part (2) in an expansion state can be adjusted by adjusting the number, the size and/or the arrangement mode of the reinforcing ribs. For example, when it is desired that the elastic member (2) as a whole expands radially outward, one or more ribs may be uniformly provided on the outer wall of the elastic member (2), and the ribs may be set to be small in size so that the elastic member (2) as a whole expands radially outward when inflated. For another example, when a plurality of sections of expansion parts with different lengths and/or different diameters are required to be formed when the elastic member (2) is expanded, a plurality of reinforcing ribs can be arranged according to the required interval length, and the size of the reinforcing ribs is set to be larger, so that the plurality of sections of expansion parts with different lengths and/or different diameters can be formed when the elastic member (2) is expanded, for example, the elastic member (2) is expanded to form a structure with a small lower diameter and a large upper diameter.
In some embodiments, a reinforcing structure may also be formed on the inner wall (23) of the elastic member (2). A reinforcing structure formed on the inner wall (23) of the elastic part (2) can be matched with the reinforcing structure (21) on the outer wall of the elastic part (2) to reinforce the elastic part (2), so that the strength, the local rigidity and the service life of the air bag are increased; in addition, the shape of the elastic member (2) in the expanded state can be adjusted.
In some embodiments, the reinforcing structure (21) may further comprise a roughened surface formed on the resilient element (2). In some embodiments, the roughened surface may be formed by a plurality of ridges and/or micro-bumps provided on the resilient member (2). For example, a plurality of spherical crown-shaped protrusions and/or textures may be provided on the surface of the elastic member (2) in a uniform or non-uniform manner, so that the outer wall (22) and/or inner wall (23) surface of the elastic member (2) is formed as a rough surface. The surface of the elastic part (2) is provided with the rough surface, so that the friction coefficient of the surface of the elastic part (2) can be increased, the friction force of the inner side surface of the object to be clamped can be increased in the using process, and the object to be clamped can be clamped more stably by the aid of the internal-support type clamp (100).
In some embodiments, an abrasion-resistant layer, a scratch-resistant layer, an oil-resistant layer and/or an antistatic layer may be provided on the outer wall (22) of the elastic member (2); wherein the outer wall (22) of the elastic element (2) is contacted with the clamped object when being inflated. In some embodiments, other materials (for example, a film made of other materials is added by spraying or soaking) may be added to the outer wall (22) of the elastic member (2), so that functions of wear resistance, no mark, oil resistance, static electricity resistance and the like can be realized. For example, the wear-resistant coating (e.g., KN17 polymer ceramic coating, KN7051 silicon carbide ceramic coating, etc.) may be applied to the outer wall of the elastic member (2) by spraying. For example, an oil repellent layer can be formed on the outer wall of the elastic member (2) by immersing an oil repellent agent (e.g., an organic fluorine compound such as a chromium complex of perfluorocarboxylic acid, an acrylic fluorocarbon resin, or an acrylic fluorocarbon sulfonamide ethyl ester). For example, an antistatic layer may be formed on the outer wall of the elastic member (2) by spraying or dipping an antistatic material (e.g., an antistatic carbon-based paint, an antistatic metal oxide-based paint, an antistatic paint such as an alkyd type, an acrylic type, an epoxy type, or a polyurethane type); alternatively, an antistatic film made of a metal oxide-based filling type antistatic material or the like may be provided on the outer wall of the elastic member (2). Also for example, an anti-indentation layer may be formed on the outer wall of the elastic member (2) by spraying or dipping an anti-fingerprint coating agent or the like; or, a pressure-proof film is arranged on the outer wall of the elastic member (2), so that a pressure-proof layer is formed.
Fig. 4 is a schematic structural view of an internal support type clamp with a telescoping mechanism (3) according to some embodiments of the present application. Fig. 5 is a schematic structural diagram of an internal support type clamp with a telescopic mechanism (3) according to another embodiment of the application.
In some embodiments, the internal bracing type clamp (100) may further include a telescopic mechanism (3), the support member (1) may be connected to the telescopic mechanism (3) directly or through a connecting component, so that the support member (1) can move along with the telescopic mechanism (3), and the elastic component (2) is fixedly connected to the support member (1) and can also move along with the movement of the support member (1). In some embodiments, the connecting member may be a bolt, a snap, a latch, or the like.
In some embodiments, as shown in fig. 4, the telescopic mechanism (3) may be a telescopic rod (e.g., an electric telescopic rod, a hydraulic telescopic rod, a pneumatic telescopic rod, etc.), the support member (1) is connected to the telescopic end of the telescopic rod through a threaded connection structure, so that the support member (1) can move along with the extension and retraction of the telescopic mechanism (3), and the elastic member (2) is connected to the support member (1) in a sealing manner, so as to also move along with the movement of the support member (1).
In some embodiments, as shown in fig. 5, the telescoping mechanism (3) may further comprise a spring (31) and a pull member (32) (e.g., a pull wire, a pull rope, a pull rod, etc.); the supporting piece (1) is connected with the spring (31) and the traction piece (32) through a connecting part, and the traction piece (32) drives the supporting piece (1) to move up and down, so that the supporting piece (1) can stretch and retract along with the stretching of the spring (31) under the traction of the traction piece (32). In some embodiments, the telescoping mechanism (3) can be controlled to telescope by a control device. Specifically, the control device can drive the traction piece (32) to move up and down to drive the support piece (1) to move up and down, so that the elastic piece (2) is driven to stretch into the inner part of the object to be clamped to clamp the object to be clamped, and then the clamping process is completed. Through setting up internal stay formula anchor clamps into the telescopic form, can realize that the article under the special scene are got and are got. For example, when the objects to be clamped are densely stacked and part of the objects are lower than the height of the objects around the objects (such as densely stacked test tubes), the objects are not suitable for being directly clamped from the outside through the clamp because of insufficient space, and the objects at the middle part are lower in height, the objects at the middle part cannot be clamped in batch by adopting the internal support type clamp without the telescopic mechanism, and the internal support type clamp can be stretched by arranging the telescopic mechanism (3), so that the batch clamping of the densely stacked objects is completed under the condition.
By setting the inner supporting type clamp (100) into a telescopic form, the object clamping in a special scene can be realized. For example, when the objects to be clamped are densely stacked and part of the objects are lower than the height of the objects around the objects (such as densely stacked bottled objects), the objects are not suitable for being directly clamped from the outside through the external clamping type clamp because of insufficient space, and the middle part of the objects cannot be clamped when the internal supporting type clamp is used for batch clamping because the height of the middle part of the objects is low, and the internal supporting type clamp (100) can be stretched through the arrangement of the stretching mechanism (3), so that the batch clamping of the densely stacked objects is completed under the condition.
Fig. 6 is a schematic structural view of an internally-supported clamp with a cushioning structure (4) according to some embodiments of the present application.
In some embodiments, the internally-braced clamp (100) may further include a cushioning structure (4). The buffer structure (4) can be sleeved on the support piece (1). When the clamp is acted by external force, the buffer structure (4) can play a role of buffering so as to protect the clamp and the object to be clamped. For example, when the internal bracing type clamp (100) is ready to clamp an object to be clamped, the elastic part (2) collides with the object to be clamped due to inaccurate positioning, and the buffer structure (4) can play a role in buffering so as to protect the clamp and the object to be clamped. In some embodiments, the cushioning structure (4) may be a bumper, a cushion pad, a cushion sheet, a cushion spring, or the like. The buffer can also be a buffer capable of being automatically adjusted, and when the elastic piece (2) collides with the object to be clamped and the stress exceeds a preset threshold value, the buffer can be automatically contracted. In some alternative embodiments, the cushioning structure (4) may further comprise a telescoping component, a pressure sensor, and a controller; the telescopic component can be connected with the controller through the pressure sensor, the telescopic component can be sleeved on the support piece (1), and the pressure sensor can be arranged at the joint of the support piece (1) and the telescopic component. In some embodiments, the telescoping member may be an electric telescoping rod, a hydraulic telescoping rod, a pneumatic telescoping rod, or the like. When the elastic piece (2) collides with the object to be clamped and the stress exceeds a preset threshold value, the telescopic component automatically contracts.
In some cases (e.g., batch picking), if the internal stay clamp does not extend accurately into the inside of the object to be picked, damage may be caused to the object. Through setting up buffer structure (like the spring, also can be other reasonable structures such as telescopic link etc.), can make the passive shrink of internal stay formula anchor clamps, alright withdraw when touching article to reduce the possible harm to article. In addition, when an object is gripped in a batch (e.g., a matrix type of gripping work) there may be a case where the work guide is not entered. For example, there may be 59 items that can be gripped by the gripper, but 1 that is not gripped. In this way, 59 gripped workpieces can be removed by the buffer structure without damaging the workpiece that is not gripped. In addition, the elastic piece (2) can be protected by arranging the buffer structure. Specifically, when the elastic member (2) extends to the object to be gripped, if the elastic member (2) encounters a relatively large resistance due to inaccurate positioning or too deep extension, the resistance is not buffered, and the elastic member (2) is damaged due to increased friction of the elastic member (2).
Fig. 7 is a schematic structural view of an internally-supported clip with an auxiliary disengaging device (5) according to some embodiments of the present application.
In some embodiments, the internally-braced clamp (100) may further include an auxiliary disengagement device (5). When the inner supporting type clamp is expected to be separated from an article, the inner supporting type clamp can not be separated in time due to reasons such as electrostatic adsorption, and the auxiliary separating device (5) is arranged outside the inner supporting type clamp, so that when the inner supporting type clamp is required to be separated, the auxiliary separating device (5) can be used for assisting the article to be separated.
In some embodiments, the auxiliary disengaging means (5) may be an air-jet arrangement. The air injection structure is arranged on the internal support type clamp (100), and is connected with the air inflation and deflation device in the use state. For example, the air injection structure can be an air injection nozzle arranged outside the internal support type clamp (100), and the air injection nozzle is connected with the air charging and discharging device in the installation or use state. Specifically, the air injection structure can be a nozzle with an annular structure, and the nozzle is provided with air injection holes distributed annularly. Under the installation state, the shower nozzle can fixed connection on interior formula anchor clamps (100) that prop to the shower nozzle that is the loop configuration and the coaxial setting of interior formula anchor clamps (100) that prop, make the fumarole that is annular distribution along the central axial evenly distributed of support piece (1) and towards the surface of elastic component (2). After the articles are sucked up, the air bag is contracted, if the articles do not fall down, the air can be blown to the middle position and/or the side position through the air jet nozzle, so that the articles are disturbed, and the articles fall off. Through set up air injection structure on internal stay formula anchor clamps, when needs break away from, utilize air injection structure to blow towards article and the absorption department of anchor clamps to supplementary article break away from.
In some alternative embodiments, the auxiliary disengaging means may be a retractable push rod disposed on the internally-supported clamp (100). For example, the telescopic push rod can be a pneumatic telescopic rod which can be installed on the internal support type clamp (100) or formed into an integrated structure with the internal support type clamp (100), when the article is sucked up, the air bag is contracted, but the article does not fall down, and the telescopic push rod can be extended out to touch the article, so that the article can fall off.
In some alternative embodiments, the auxiliary disengaging device may also be a vibrating device. The internal support type clamp (100) is arranged on the vibrating device. For example, a micro-vibration device may be installed on the inner supporting type clamp (100), and when the article is sucked up, the air bag is contracted, but the article does not fall down, and the micro-vibration device may vibrate or shake the inner supporting type clamp (100) to drop the article. For example, the vibration device may be a cell phone vibrator or similar mechanism or device in an existing cell phone.
The internal bracing fixture disclosed in the present application may bring beneficial effects including but not limited to:
the internal support type clamp has the advantages of small volume, light weight, simple structure and low manufacturing cost, and can clamp objects with different sizes and similar shapes in a certain range due to the soft property of the silica gel air bag, and does not damage the clamped objects; can quickly and stably clamp ring-shaped and bottle-shaped fragile and soft objects without damaging the surfaces of the objects. After the elastic piece of the internal support type clamp is sleeved inside an object, the elastic piece expands and is attached to the inner surface of the object, and the object to be clamped can be clamped from the inside; furthermore, the first elastic piece can be the same as the shape of the inner side of the clamped object, so that local stress concentration is not generated, and the inner surface of the object is not easy to damage. Furthermore, the air pressure in the air bag is adjustable, namely the force of the inner support can be adjusted, and thin-walled or easily damaged workpieces can be safely picked up; further, even if the pneumatic system is overloaded or the pneumatic system is not accurately positioned and collides, the articles cannot be damaged; further, when waiting to press from both sides and getting object medial surface for complicated profile, benefit from the characteristic that silica gel can produce very big deformation, need not carry out complicated design in advance, also can effectively laminate, realize pressing from both sides and get.
