Description

Technical Field

[0001] This invention belongs to the field of production equipment, specifically a universal conformal fixing device. Background Technology

[0002] In daily life or industrial production, cylindrical items require special supports for securing them during transportation to prevent them from rolling off and damaging equipment or parts, or even falling off the transport vehicle and causing injury or death. In addition, some oddly shaped items, equipment or parts need to be stored according to their shape to avoid deformation.

[0003] In the two cases mentioned above, the shapes of the items that need to be fixed are different, and the shapes of the fixing devices used to store them are also different. Different types of fixing devices need to be made according to the shape of the items, which leads to increased costs and extended production cycles. Summary of the Invention

[0004] To address the aforementioned shortcomings in the existing technology, the present invention aims to provide a universal conformal fixing device, thereby enabling the present invention to fix objects of different shapes.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a universal conformal fixing device, comprising a base, wherein a plurality of support units are provided on the base, wherein each of the plurality of support units includes a piston rod for supporting the fixed object, and an elastic body is provided between the piston rod and the base.

[0006] As a limitation of the present invention: the elastomer is disposed in the sleeve.

[0007] As a limitation of the present invention: the sleeve includes an inner sleeve and an outer sleeve, an elastomer is disposed in the inner sleeve, the inner sleeve is disposed in the outer sleeve, the outer diameter of the inner sleeve is smaller than the inner diameter of the outer sleeve, so that a medium cavity is formed between the inner sleeve and the outer sleeve, the medium cavity is connected to a variable volume medium storage tank through a connecting pipe, and the medium cavity and the medium storage tank contain the medium.

[0008] As a limitation of the present invention: the medium storage box includes a medium box and an exhaust box, the medium box and the exhaust box are separated by a medium partition that is slidably disposed inside the medium storage box; the medium box is connected to the medium cavity of the support unit, the exhaust box is provided with an elastic body along the sliding direction of the medium partition, the exhaust box wall is provided with an exhaust hole communicating with the outside, and the medium is disposed in the medium box.

[0009] As a limitation of the present invention: a solenoid valve is provided on the connecting pipe.

[0010] As a limitation of the present invention: the piston rod has a contact body at the end facing the object being fixed.

[0011] As a limitation of the present invention: a lower cover plate is provided at the end of the sleeve away from the ground, and the piston rods of the plurality of support units are all provided through the lower cover plate.

[0012] As a limitation of the present invention: a guide plate parallel to the lower cover plate is provided on the side away from the ground, and the piston rods of several support units are all provided through the guide plate. The inner diameter of the hole on the guide plate for the piston rod to pass through is larger than the outer diameter of the piston rod. The guide plate is connected to a reciprocating motion mechanism for making it reciprocate relative to the lower cover plate.

[0013] As a limitation of the present invention: the reciprocating motion mechanism includes a push bar arranged parallel to one side of the guide plate, the side of the push bar that contacts the guide plate having one or more guide protrusions, the guide protrusions having inclined surfaces, the side of the guide plate that contacts the guide protrusions having guide grooves adapted to the shape of the guide protrusions, and the end of the push bar having a push mechanism for moving it along the inclined surface of the guide protrusions; the reciprocating motion mechanism also includes a return spring arranged on the other side of the guide plate.

[0014] As a limitation of the present invention: the guide plate is provided with an upper cover plate on the side away from the ground, and the piston rods of several support units are all provided through the upper cover plate. One or more guide ribs are provided on the guide plate along the reciprocating motion direction of the guide plate. Guide rib tracks are provided on the upper cover plate and the lower cover plate at positions that match the guide ribs.

[0015] By adopting the above technical solution, the beneficial effects achieved by the present invention compared with the prior art are as follows:

[0016] (1) The present invention sets up several support units that are supported by elastic bodies to support and fix objects. Under the action of the object's gravity, the elastic body of the support unit in contact with the support unit is compressed and the piston rod moves down. The piston rod of the support unit that is not in contact with the object remains in a supported state under the action of the elastic body. The object can be surrounded by the piston rod in the supported state to form a fixed structure. The same fixing device can fix objects of any shape, which has a strong adaptability. Furthermore, the elastic body is set in the sleeve, and the sleeve provides guidance for the movement of the piston rod, making the structure more stable.

[0017] (2) The sleeve of the support unit of the present invention contains a medium, which is connected to a medium storage tank with variable volume. When the piston rod moves down under the gravity of the object, the medium cavity is compressed and the medium flows from the sleeve to the medium storage tank. The presence of the medium can help maintain the downward movement of the piston rod, making the state of the object placed by the present invention more stable. Furthermore, the medium cavity is connected to the medium storage tank through a connecting pipe. A solenoid valve is provided on the connecting pipe. The solenoid valve can further maintain the flow state of the medium, thereby more stably assisting in maintaining the downward movement of the piston rod.

[0018] (3) The present invention is also provided with an upper cover plate, a lower cover plate, and a guide plate. The guide plate is disposed between the upper cover plate and the lower cover plate and can reciprocate within the space formed by the upper cover plate and the lower cover plate. When the present invention places an object, the piston rod is pressed down and the lower cover plate is pushed out. The piston rod is clamped under the action of the three-layer plate, which further fixes the downward position of the piston rod. In addition, if the medium leaks during use, the piston rod can still maintain its position due to the action of the three-layer plate, making the state after the object is placed more stable.

[0019] In summary, this invention, by setting up several piston rods to form a shape adapted to the object being placed, can fix objects of any shape using the same fixing device. It has extremely strong adaptability and a stable structure, making it suitable for all scenarios that require the placement or fixing of objects. Attached Figure Description

Detailed Implementation

[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the general-purpose fixing device described herein is a preferred embodiment and is only used for illustration and explanation of the present invention, and does not constitute a limitation thereof.

[0032] The directional terms or positional relationships used in this invention, such as "up," "down," "left," and "right," are based on the positional relationships in the accompanying drawings of this specification. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this invention.

[0033] General Fixing Device for Examples

[0034] This implementation example Figures 1-9 As shown, a general-purpose fixing device includes several support units 3 arranged in an array. Each support unit 3 can be individually retracted under the action of force. It also includes a lower cover plate 5, a guide plate 7, and an upper cover plate 8 that clamp the support units 3 to fix the retracted state. The support units 3 are connected to a media storage tank 4 with variable volume.

[0035] like Figure 1As shown, in this embodiment, the support unit 3 is arranged in 13 rows and 8 columns. The number of support units 3 can be adjusted according to actual needs. The support unit 3 is set on the base 1. In this embodiment, the base 1 is a square box structure. The support unit 3 is fixedly set on the bottom surface inside the box by the clamping plate 2. The support unit 3 includes a piston rod 36 for supporting the fixed object. A contact body 31 is fixed at the end of the piston rod 36 away from the base 1. The contact body 31 can increase the friction between this embodiment and the fixed device. The material of the contact body 31 can be determined according to the fixed object, such as wood, rubber, polyurethane, metal, etc. An elastic body 32 is provided between the piston rod 36 and the base 1. When an object is placed on this embodiment, through the elastic deformation of the elastic body 32, the piston rod 36 in contact with the placed object is pressed down under the action of gravity, so that the arrayed support units 3 form a shape adapted to the placed object, thereby placing or fixing the placed object. Furthermore, the elastic body 32 can be any object that undergoes elastic deformation when subjected to external force, such as a spring, latex, etc. In this embodiment, the elastic body 32 is a spring.

[0036] Furthermore, the elastic body 32 is disposed in the sleeve, and the lower end of the piston rod 36 is connected to the elastic body 32. The sleeve provides space and guidance for the elastic deformation of the elastic body 32, allowing the piston rod 36 to move in the vertical direction shown in the figure. In this embodiment, the sleeve includes an inner sleeve 33 and an outer sleeve 34. The elastic body 32 is disposed in the inner sleeve 33, and the inner sleeve 33 is disposed in the outer sleeve 34. The outer diameter of the inner sleeve 33 is smaller than the inner diameter of the outer sleeve 34, so that the outer sleeve 34 surrounds the inner sleeve 33, forming a medium cavity 35 between the inner sleeve 33 and the outer sleeve 34. The outer sleeve 34 is fixedly disposed on the bottom surface inside the base 1 box structure by a clamping plate 2. The piston rod 36 is connected to the base 1 through the elastic body 32, the inner sleeve 33, and the outer sleeve 34. The piston rod 36 and the inner sleeve 33 are sealed, while the inner sleeve 33 and the outer sleeve 34 are connected, so that when the piston rod 36 is pressed down, the space of the medium cavity 35 is compressed.

[0037] The medium cavity 35 is connected to the variable-volume medium storage tank 4 via a connecting pipe (the structure of the connecting pipe is omitted in the attached drawing to avoid confusion), and the medium cavity 35 and the medium storage tank 4 contain the medium. Since several support units 3 are arranged in an array, the medium cavities 35 of multiple support units 3 can be connected to the medium storage tank 4 via the same connecting pipe. In this embodiment, the support units 3 are arranged in 13 rows and 8 columns, so that support units 3 in the same column are connected to the medium storage tank 4 via the same connecting pipe. Therefore, this embodiment has 13 connecting pipes, and correspondingly, the medium storage tank 4 has 13 connecting holes 45 for connecting to the connecting pipes. The medium can be a liquid such as water or oil, or a gas. It should be noted that when using a gaseous medium, because gas is compressible, an external pressure gauge and pressure-holding device are required to ensure the stability of the piston rod 36.

[0038] Furthermore, in this embodiment, the media storage box 4 is a rectangular box disposed inside the box structure of the base 1, located at one end along the length direction of the box structure of the base 1 (i.e., along the row direction of the array of support units 3). A media partition 41 is slidably disposed inside the media storage box 4, dividing the media storage box 4 into a media box 42 and an exhaust box 43. The media box 42 is connected to the media cavity 35 of the support unit 3. In this embodiment, the media partition 41 is disposed horizontally inside the media storage box 4, such that the lower half of the media storage box forms the media box 42 for containing the media, and the upper half forms the exhaust box 43 for changing the volume of the media box 42. An elastic body 32 is disposed inside the exhaust box 43 along the sliding direction of the media partition 41, and an exhaust hole 44 communicating with the outside is disposed on the wall of the exhaust box 43. When the piston rod 36 is pressed down, the space of the medium cavity 35 in the support unit 3 is compressed, the medium flows to the medium tank 42, the medium partition 41 moves upward under this action, the elastic body 32 is compressed, and the gas in the exhaust tank 43 is discharged through the exhaust port 44. The elastic body 32 here can be any object that undergoes elastic deformation after being subjected to external force, such as a spring, latex, etc. In this embodiment, the elastic body 32 here is a spring. In order to ensure that the stroke of the medium partition 41 is sufficient, the exhaust port 44 in this embodiment is located on the upper side of the exhaust tank 43, while the connecting pipe is located on the lower side of the medium tank 42. In addition to the structure described in this embodiment, the medium storage tank 4 can be replaced by other structures with variable volume, such as a balloon.

[0039] Furthermore, a solenoid valve is installed on the connecting pipe to effectively prevent automatic backflow of the medium. When this embodiment is unloaded, the solenoid valve is de-energized, the valve is closed, the connecting pipe is in a closed state, the springs are all in a free state, and the piston rod 36 is pushed out to its highest height. When an object is placed on this embodiment, the solenoid valve is energized first, the valve opens, the connecting pipe is unobstructed, and after placement, the height of the piston rod 36 of the support unit 3 decreases, the space of the medium cavity 35 is compressed, and the medium flows into the medium storage tank 4. When the object is placed stably, the solenoid valve is de-energized, the valve closes, the connecting pipe returns to a closed state, the medium will not backflow, and the position of the piston rod 36 is stabilized.

[0040] To ensure the stability of the piston rod 36 and the stability of the object after placement, a lower cover plate 5 is provided at the end of the sleeve away from the ground, i.e., above the sleeve. In this embodiment, the lower cover plate 5 is a plate-shaped structure whose size is adapted to the base 1, and the piston rods 36 of several support units 3 are all installed through the lower cover plate 5. Inside the box structure formed by the lower cover plate 5 and the base 1, support legs 6 are also provided to support the lower cover plate 5. The support legs 6 are distributed in the gaps formed by several support units 3, and the number of them can be adjusted according to the size of the lower cover plate 5.

[0041] Furthermore, a guide plate 7 parallel to the lower cover plate 5 is provided on the side of the lower cover plate 5 away from the ground, i.e., above the lower cover plate 5, and an upper cover plate 8 parallel to the guide plate 7 is provided on the side of the guide plate 7 away from the ground, i.e., above the guide plate 7. A cavity for accommodating the guide plate 7 is formed between the upper cover plate 8 and the lower cover plate 5. The width dimension of the guide plate 7 (i.e., the column direction along which the support unit 3 is arrayed) is adapted to the cavity, and the length dimension of the guide plate 7 (i.e., the row direction along which the support unit 3 is arrayed) is smaller than the cavity, so that the guide plate 7 can reciprocate along its length direction in the cavity.

[0042] The piston rods 36 of several support units 3 are arranged to pass through the lower cover plate 5, the guide plate 7, and the upper cover plate 8 from bottom to top. Since the upper cover plate 8 and the lower cover plate 5 are fixedly arranged, the diameter of the through holes on the upper cover plate 8 and the lower cover plate 5 for the piston rods 36 to pass through is adapted to the piston rods 36. Since the guide plate 7 needs to reciprocate along its length, the inner diameter of the through hole on the guide plate 7 for the piston rods 36 to pass through must be larger than the outer diameter of the piston rods 36. In this embodiment, the hole on the guide plate 7 for the piston rods 36 to pass through is an oblong hole, including two semicircular parts and a long part. The diameter of the semicircular part is adapted to the piston rods 36, and the length of the long part is adapted to the stroke of the reciprocating motion of the guide plate 7.

[0043] The guide plate 7 is connected to a reciprocating motion mechanism for reciprocating relative to the lower cover plate 5. In this embodiment, the reciprocating motion mechanism is disposed in the cavity formed between the upper cover plate 8 and the lower cover plate 5 for accommodating the guide plate 7, and includes a pusher 9 arranged parallel to one side of the guide plate 7. In this embodiment, the pusher 9 is arranged along the length of the guide plate 7 on the side close to the media storage tank 4. One or more guide protrusions 10 are provided on the side of the pusher 9 that contacts the guide plate 7, i.e., the side facing the guide plate 7. In this embodiment, there are 5 guide protrusions 10. The guide protrusions 10 include inclined surfaces with a slope. The side of the guide plate 7 that contacts the guide protrusions 10 is provided with guide grooves that are adapted to the shape of the guide protrusions 10. When the pusher 9 is pushed forward in the direction of the inclined surface of the guide protrusion 10 ( Figure 8 (in the direction of the arrow), the inclined surface of the guide slide protrusion 10 and the inclined surface of the guide slide groove move alternately, causing the guide slide plate 7 to move along its length direction ( Figure 8 (The arrow in the image is pointing in the direction of the arrow). The setting of the guide slide protrusion 10 and the guide slide groove allows the push bar 9, which moves along the width direction of the guide slide 7, to drive the guide slide 7 to move along the length direction, so that the motion is transmitted vertically.

[0044] The end of the push bar 9 is provided with a push mechanism 11 for moving it along the inclined surface of the guide slide protrusion 10. In this embodiment, the push mechanism 11 includes a power-off self-locking motor located at the end of the push bar 9. The power-off self-locking motor is connected to the push bar 9 via a lead screw, and the power-off self-locking motor can push the push bar 9 out by rotating itself. Of course, the push bar 9 can also be pushed out using other structures, such as a paddle structure in the direction of movement of the push bar 9, with the paddle extending to the outside of the base 1 housing structure. The push bar 9 can be moved by manually moving the paddle, and the position of the paddle can be fixed by setting a limiting device. At the same time, in order to ensure that the guide plate 7 can return smoothly in the non-working state, a return spring 12 (shown as a cylinder in the figure) is provided on the side of the guide plate 7 away from the push bar 9, along the return direction of the guide plate 7. The return spring 12 can be replaced by any component that can play a return role, such as a nitrogen cylinder.

[0045] Because the support unit 3 and the storage box contain springs, this embodiment can be stored and used at any angle, greatly improving its applicability.

[0046] Furthermore, to make the structure more stable, a support seat 13 is provided between the upper cover plate 8 and the lower cover plate 5, penetrating the guide plate 7 to support the upper cover plate 8. In this embodiment, the support seat 13 is set on the upper cover plate 8, but the support seat 13 can also be set on the lower cover plate 5. The number and setting position of the support seats 13 can be adjusted as needed. Correspondingly, a support seat through hole 14 is provided on the guide plate 7. Since the support seat 13 needs to reciprocate, in this embodiment, the support seat through hole 14 is an elongated hole, including two semicircular parts and a long part. The diameter of the semicircular parts is adapted to the support seat 13, and the length of the long part is adapted to the stroke of the reciprocating motion of the guide plate 7.

[0047] To make the movement of the guide plate 7 more stable, one or more guide ribs 15 are provided on the guide plate 7 along the reciprocating direction of the guide plate 7, and guide rib tracks 16 are provided on the upper cover plate 8 and the lower cover plate 5 at positions matching the guide ribs 15. In this embodiment, three guide ribs 15 are provided on both the upper and lower surfaces of the guide plate 7, and correspondingly, three guide rib tracks 16 are also provided on the upper cover plate 8 and the lower cover plate 5.

[0048] To make the movement of the push bar 9 more stable, push bar 9 is provided with push bar ribs 17 arranged along the movement direction of push bar 9 on the surface of push bar 9 facing the upper cover plate 8 and the lower cover plate 5, and push bar rib 17 tracks are provided on the upper cover plate 8 and the lower cover plate 5 at positions matching the push bar ribs 17.

[0049] In this embodiment, when no object is placed, all circuits are disconnected, the solenoid valve is closed, the springs are in a free state, and the piston rod 36 is fully extended to its highest height. The motor pulls the push bar 9 back, and the guide plate 7 returns to its return state under the action of the return spring 12. When an object is placed, the solenoid valve is energized, the connecting pipe is unobstructed, and the support unit 3 in contact with the object is compressed, allowing the medium to flow back into the storage tank through the connecting pipe. After the object is placed stably, the solenoid valve is de-energized, the valve closes, the medium does not flow back, and the piston rod 36 is stabilized in its extended position. (If the medium is gas, due to the compressibility of gas, an external pressure device is required to ensure the stability of the piston rod 36 position through automatic adjustment.) At this time, the self-locking motor is also energized, pushing out the push bar 9, which in turn pushes out the guide plate 7. Under the action of the three-layer plate, the piston rod 36 is locked, further ensuring the stability of the extended position. When it is necessary to remove the object, the reverse operation is repeated.
