Mounting structure of an electric trolley

Abstract

This application provides an installation structure for an electric actuator. The operator places one end of the electric cylinder to be installed into the mounting cavity formed by a fixed housing and a movable housing, while the other end extends through a through slot in the fixed housing. During installation, since the fixed housing and the movable housing are respectively equipped with a first magnetic attractor and a second magnetic attractor, these magnetic attractors automatically attract each other after the electric cylinder is placed in, thereby driving the movable housing to slide closer to the fixed housing. Under the action of magnetic force, the movable housing and the fixed housing will respectively abut against the two ends of the electric cylinder, thus forming a clamping and positioning structure, constraining and fixing the two ends of the electric cylinder in the device. The operator only needs to push or pull the movable housing to complete the installation or release, without the need for tools, significantly shortening the replacement time and benefiting production continuity.

Description

Technical Field

[0001] This application relates to the field of composite material molding, and more particularly to a mounting structure for an electric actuator. Background Technology

[0002] In the field of composite material molding, in order to achieve precise control over the opening and closing of vacuum pipes or resin injection pipes, it is usually necessary to use a pipe switching device to open or close the pipes.

[0003] Especially in the molding process of large composite material structures, due to the huge size of the parts and the huge molding space requirements, the existing pipeline switching system is often composed of multiple hydraulic cylinders, hydraulic pumps, vacuum distributors, electric cylinders and solenoid valve arrays, and is generally installed and fixed in a planar layout.

[0004] The electric cylinder is secured with screws at both ends, ensuring it remains stationary during operation. A fixed outer casing protects the cylinder from external impacts. However, if the electric cylinder malfunctions or needs replacement, the outer casing must first be removed using screws or bolts. Then, the screws or bolts at the cylinder's end must be loosened for proper installation. In composite material molding, replacing the electric cylinder can be extremely time-consuming, making rapid replacement difficult. This delay can allow resin to enter the vacuum pipe or become difficult to cut off, exacerbating the problem. If the machine is stopped immediately, the resin injected later will not be consistent with the resin injected earlier, affecting the final molding quality. Utility Model Content

[0005] In view of this, it is necessary to provide a mounting structure for an electric linear actuator to solve the above problems.

[0006] Embodiments of this application provide a mounting structure for an electric linear actuator, comprising:

[0007] Mounting base with mounting surface;

[0012] An electric cylinder has one end housed in the mounting cavity and the other end extending to the outside through the through groove. The first magnetic attractor attracts the second magnetic attractor, causing the movable housing to move towards the fixed housing. Ultimately, the fixed housing and the movable housing abut against the two ends of the electric cylinder to fix the electric cylinder.

[0013] In at least one embodiment of this application, a slide rail is provided protruding from the mounting surface of the mounting base;

[0014] The movable housing includes:

[0015] The shielding member forms the mounting cavity between itself and the fixed housing;

[0016] The connector has a sliding groove, the shield is fixedly connected to the connector, and the sliding groove is slidably connected to the slide rail.

[0017] In at least one embodiment of this application, the slide rail is provided with a limiting groove, and a plurality of limiting blocks are equidistantly arranged on the slide rail. The limiting blocks are located in the limiting groove, and the connector is provided with an abutting block. The abutting block is located in the limiting groove and abuts against one of the limiting blocks to fix the movable housing.

[0018] In at least one embodiment of this application, the slide rail is provided with a movable groove communicating with the limiting groove, the movable groove is disposed away from the mounting surface, and there is a gap between the fixed housing and the movable housing;

[0019] The movable housing is moved in a direction away from the mounting surface so that the abutment block is received in the movable groove, thereby releasing the movable housing.

[0020] In at least one embodiment of this application, the movable housing further includes:

[0021] A first connecting plate is installed at the end of the connector near the electric cylinder;

[0022] The second connecting plate is installed at one end of the connector near the electric cylinder and is arranged parallel to the first connecting plate;

[0023] A locking rod passes sequentially through the first connecting plate, one end of the electric cylinder, and the second connecting plate;

[0025] In at least one embodiment of this application, the length of the slide rail is set along the length direction of the electric cylinder.

[0026] In at least one embodiment of this application, the mounting structure of the electric actuator further includes:

[0027] A clamping block is located at the end of the electric cylinder away from the movable housing;

[0028] A fixing plate is disposed on the mounting surface, and a clamping groove is formed between the fixing plate and the clamping block.

[0029] In at least one embodiment of this application, the clamping block protrudes outward on the side near the fixing plate to form a first abutting arc surface, and the fixing plate protrudes outward on the side near the clamping block to form a second abutting arc surface, with the first abutting arc surface and the second abutting arc surface being disposed opposite to each other;

[0030] The electric cylinder moves to drive the clamping block closer to or away from the fixed plate, so that the first abutting arc surface moves closer to or away from the second abutting arc surface, thereby closing or opening the pipeline.

[0031] In at least one embodiment of this application, the mounting structure of the electric actuator further includes:

[0032] Guide plates are disposed on both sides of the clamping block and form guide grooves. The clamping block is located in the guide grooves, and both sides of the clamping block are respectively attached to the two guide plates.

[0033] In at least one embodiment of this application, the mounting structure of the electric actuator further includes:

[0034] A retaining ring is provided on the mounting surface.

[0035] The mounting structure of the electric linear actuator implemented in this embodiment will have at least the following beneficial effects:

[0036] The aforementioned electric actuator mounting structure allows the operator to place one end of the electric cylinder to be installed into the mounting cavity formed by the fixed housing and the movable housing, while the other end protrudes through the through slot in the fixed housing. During installation, since the fixed housing and the movable housing are respectively equipped with a first magnetic attraction component and a second magnetic attraction component, these components automatically attract each other after the electric cylinder is placed in, thereby driving the movable housing to slide closer to the fixed housing. Under the action of magnetic force, the movable housing and the fixed housing will respectively abut against the two ends of the electric cylinder, thus forming a clamping and positioning structure, constraining and fixing the two ends of the electric cylinder in the device. The operator only needs to push or pull the movable housing to complete the installation or release, without the need for tools, significantly shortening the replacement time and facilitating production continuity. This electric actuator mounting structure allows for the disassembly of the electric cylinder in the shortest possible time, avoiding quality problems such as inconsistent resin injection before and after the machine stops, and improving the stability of the molding process and the consistency of the finished product.

[0054] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0055] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0056] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0057] Embodiments of this application provide a mounting structure 100 for an electric linear actuator, comprising:

[0058] Mounting base 110 has mounting surface 110a;

[0059] A fixed housing 120 is mounted on the mounting surface 110a, and the fixed housing 120 is provided with a through groove 120a;

[0060] The movable housing 130 is slidably connected to the mounting base 110, and a mounting cavity 130a is formed between the fixed housing 120 and the movable housing 130;

[0061] The first magnetic suction element 140 is disposed on the fixed housing 120;

[0062] The second magnetic suction element 150 is disposed on the movable housing 130;

[0063] The electric cylinder 160 has one end housed in the mounting cavity 130a and the other end extending to the outside through the through groove 120a. The first magnetic attractor 140 attracts the second magnetic attractor 150, causing the movable housing 130 to move towards the fixed housing 120. Finally, the fixed housing 120 and the movable housing 130 abut against the two ends of the electric cylinder 160 to fix the electric cylinder 160.

[0064] Please refer to Figures 1-6 In this embodiment, the operator places one end of the electric cylinder 160 to be installed into the mounting cavity 130a formed by the fixed housing 120 and the movable housing 130, while the other end extends out through the through groove 120a of the fixed housing 120.

[0065] During installation, since the fixed housing 120 and the movable housing 130 are respectively provided with a first magnetic 140 and a second magnetic 150, when the electric cylinder 160 is placed in, the first magnetic 140 and the second magnetic 150 will automatically attract each other, thereby driving the movable housing 130 to slide closer to the fixed housing 120.

[0066] The movable housing 130 and the fixed housing 120 will abut against the two ends of the electric cylinder 160 under the action of magnetic force, thereby forming a clamping and positioning structure, so that the two ends of the electric cylinder 160 are constrained and fixed in the device.

[0067] Operators can simply push or pull the movable housing 130 to complete the installation or release without tools, which greatly shortens the replacement time and is beneficial to production continuity.

[0068] The mounting structure 100 of this electric actuator allows for the disassembly of the electric cylinder 160 in the shortest possible time, avoiding quality problems such as inconsistent resin injection before and after the machine stops, and improving the stability of the molding process and the consistency of the finished product.

[0069] The magnetic structure enables automatic alignment and fixation, reducing human installation errors and improving the positioning accuracy of the electric cylinder 160 in the equipment.

[0070] Ensuring that the electric cylinder 160 is subjected to symmetrical forces at both ends and is installed in a consistent manner helps to maximize its motion performance and extend its lifespan.

[0071] It should be noted that the mounting base 110 is roughly a rectangular plate, the mounting surface 110a is a plane on one side of the mounting base 110, the fixed housing 120 is roughly semi-circular with a through groove 120a at one end and an open space cover at the other end, the through groove 120a is roughly a rectangular through channel, and the movable housing 130 is roughly a semi-circular cover with a hollow internal structure.

[0072] Both the first magnetic attractor 140 and the second magnetic attractor 150 are magnets, and both the first magnetic attractor 140 and the second magnetic attractor 150 are cylindrical neodymium magnets.

[0073] The electric cylinder 160 consists of an electric motor and a telescopic cylinder.

[0074] In at least one embodiment of this application, a slide rail 111 is provided protruding on the mounting surface 110a of the mounting base 110;

[0075] The movable housing 130 includes:

[0076] The shielding member 131 forms the mounting cavity 130a between itself and the fixed housing 120;

[0077] The connector 132 has a sliding groove, the shield 131 is fixedly connected to the connector 132, and the sliding groove is slidably connected to the slide rail 111.

[0078] Please refer to Figures 1-6 In this embodiment, a long strip slide rail 111 is formed on the mounting surface 110a of the mounting base 110, and there are two slide rails 111. The connecting member 132 of the movable housing 130 is provided with a sliding groove, which is slidably connected to the slide rail 111, so that the movable housing 130 can slide smoothly in a set direction (usually the axial direction of the electric cylinder 160) under the guidance of the slide rail 111, and is not easy to deviate or tilt.

[0079] The shield 131, as part of the movable housing 130, forms a side mounting cavity 130a with the fixed housing 120 to accommodate the electric cylinder 160. When the electric cylinder 160 is installed, it can be placed into the mounting cavity 130a formed by the shield 131 and the fixed housing 120.

[0080] The movable housing 130 slides along the slide rail 111 via the slide groove and moves closer to the fixed housing 120 under the magnetic attraction, thereby clamping and fixing the electric cylinder 160. Reverse sliding can release the clamping and achieve quick disassembly of the electric cylinder 160.

[0081] The design of the slide rail 111 and the slide groove effectively guides the movement direction of the movable housing 130, preventing the movable housing 130 from deviating, jamming or mis-displaced during movement, and ensuring that the electric cylinder 160 is installed in an accurate and reliable position.

[0082] The movable housing 130 can slide out directly, releasing the mounting cavity 130a, allowing the electric cylinder 160 to be quickly removed or inserted, enabling tool-free quick replacement and significantly reducing downtime.

[0083] In at least one embodiment of this application, the slide rail 111 is provided with a limiting groove 111a, and a plurality of limiting blocks 112 are equidistantly arranged on the slide rail 111. The limiting blocks 112 are located in the limiting groove 111a, and the connector 132 is provided with an abutting block 133. The abutting block 133 is located in the limiting groove 111a and abuts against one of the limiting blocks 112 to fix the movable housing 130.

[0084] Please refer to Figures 1-6 In this embodiment, the limiting groove 111a is arranged along the length direction of the slide rail 111 (i.e. the sliding direction of the movable housing 130) to form an internal channel. Multiple limiting blocks 112 on the slide rail 111 are arranged at equal intervals inside the limiting groove 111a as "anchor points" for fixing the position.

[0085] The connector 132 is part of the movable housing 130. The connector 132 has an abutment block 133 inside. The abutment block 133 is located in the limiting groove 111a. During the sliding process of the movable housing 130, the abutment block 133 will move along the limiting groove 111a. When it moves to align with a certain limiting block 112, the two will mechanically abut, thereby accurately positioning and holding the movable housing 130 in that position.

[0086] Since the limiting blocks 112 are arranged at equal intervals, the operator can slide the movable housing 130 to make the abutting block 133 engage with different limiting blocks 112, so as to achieve controllable positioning and fixation at multiple positions. If release is required, the fixed state can be released by simply disengaging the abutting block 133 from the limiting block 112 (such as lifting it up), so as to move or disassemble the movable housing 130.

[0087] It is beneficial to adapt to electric cylinders of different specifications or stroke lengths 160, thereby improving the system's adaptability and adjustment flexibility.

[0088] The mechanical contact between the blocks makes the fixing force more secure, ensuring that the movable housing 130 does not loosen or shift during operation or impact, thus improving the stability of the equipment operation.

[0089] In at least one embodiment of this application, the slide rail 111 is provided with a movable groove 111b that communicates with the limiting groove 111a. The movable groove 111b is disposed away from the mounting surface 110a, and there is a gap between the fixed housing 120 and the movable housing 130.

[0090] The movable housing 130 is moved in a direction away from the mounting surface 110a so that the abutment block 133 is received in the movable groove 111b, thereby releasing the movable housing 130.

[0091] Please refer to Figures 1-6 In this embodiment, a movable groove 111b communicating with a limiting groove 111a is provided on the slide rail 111, and the movable groove 111b is located away from the mounting surface 110a (usually the upper part or the outer side of the slide rail 111). The movable housing 130 is connected to the slide rail 111 through the sliding groove of the connector 132, and is provided with an abutting block 133. Under normal circumstances, the abutting block 133 is located in the limiting groove 111a and abuts against a certain limiting block 112 to achieve positioning and fixation.

[0092] A gap is provided between the fixed housing 120 and the movable housing 130 to allow the movable housing 130 to move (i.e., lift) in a direction perpendicular to the mounting surface 110a. When the movable housing 130 needs to be released, the operator only needs to slightly lift the movable housing 130 in a direction away from the mounting surface 110a to disengage the abutment block 133 from the original locking limit block 112 and enter the movable groove 111b.

[0093] After the abutment block 133 enters the movable groove 111b, it does not engage with the limit block 112. The movable housing 130 can then slide freely on the slide rail 111 or be completely disassembled, enabling the rapid release of the electric cylinder 160, which facilitates maintenance, replacement, or reinstallation.

[0094] The movable housing 130 can be released, slid, or disassembled without the need to tighten screws or use tools, greatly improving maintenance efficiency.

[0095] The movable housing 130 can be unlocked and the electric cylinder 160 can be pulled out within seconds, greatly reducing downtime and preventing material scrap caused by vacuum interruption or resin retention.

[0096] In at least one embodiment of this application, the movable housing 130 further includes:

[0097] The first connecting plate 170 is installed at the end of the connector 132 near the electric cylinder 160;

[0098] The second connecting plate 171 is installed at one end of the connector 132 near the electric cylinder 160 and is arranged parallel to the first connecting plate 170.

[0099] The locking rod 173 passes sequentially through the first connecting plate 170, one end of the electric cylinder 160, and the second connecting plate 171;

[0100] The locking block 174 engages with one end of the locking rod 173 and abuts against the side of the second connecting plate 171 away from the first connecting plate 170, while the other end of the locking rod 173 abuts against the first connecting plate 170.

[0101] Please refer to Figures 1-6 In this embodiment, the first connecting plate 170 and the second connecting plate 171 are respectively disposed on the connecting member 132 of the movable housing 130 and are arranged in parallel to each other, and are located at one end of the electric cylinder 160 (the telescopic end of the electric cylinder 160).

[0102] The locking rod 173 is roughly semi-circular at one end and round at the other. It abuts against the first connecting plate 170 from one side, then passes sequentially through the first connecting plate 170, the mounting hole (or threaded hole) at the tail of the electric cylinder 160, and the second connecting plate 171 until its end. A locking block 174 is located at the end of the locking rod 173 (the end protruding from the second connecting plate 171) and abuts against the side of the second connecting plate 171 away from it, serving a locking and limiting function. The other end of the locking rod 173 is abutted against the first connecting plate 170. The locking block 174 is roughly a retaining ring.

[0103] When installing the electric cylinder 160, the locking rod 173 is inserted from one side of the first connecting plate 170, passes through the electric cylinder 160 and the second connecting plate 171, and the locking block 174 engages with the end of the locking rod 173 to form a clamp with the second connecting plate 171. Since the locking rod 173 is held against the first connecting plate 170 and the other end is locked by the locking block 174, a rigid closed ring is formed to clamp the tail of the electric cylinder 160. When disassembling, the locking rod 173 can be pulled out from one side simply by releasing the locking block 174, thus quickly releasing the tail of the electric cylinder 160.

[0104] The through-type locking rod 173 and clamping plate structure provide a fixing method of surface contact and rigid abutment, which effectively improves the installation stability of the electric cylinder 160 during operation and prevents loosening or displacement caused by push-pull load.

[0105] The parallel arrangement of the first connecting plate 170, the second connecting plate 171, and the through locking rod 173 forms a stable and symmetrical clamping mechanism, ensuring that the axis of the electric cylinder 160 is coaxial with the housing structure, which is beneficial to improving the linear accuracy and motion consistency of the electric cylinder 160 during operation.

[0106] The locking block 174 is located at the end of the locking rod 173 and abuts against the outer side of the second connecting plate 171. It forms a reverse limit in the direction of the electric cylinder 160's operating thrust, which can effectively prevent the locking rod 173 from accidentally slipping out due to tension or vibration, and has good resistance to working conditions and impact.

[0107] In at least one embodiment of this application, the length of the slide rail 111 is arranged along the length direction of the electric cylinder 160.

[0108] Please refer to Figures 1-6In this embodiment, the electric cylinder 160 has a linear structure, and its pushing and pulling action extends along its own length direction. The slide rail 111 is also arranged in the same direction, so that the sliding direction of the movable housing 130 when installing, adjusting or releasing the electric cylinder 160 is consistent with the movement direction of the electric cylinder 160 itself. The same-direction layout allows the electric cylinder 160 to be pushed in or pulled out along its own axial direction during installation, without the need for lateral or rotational adjustment. The operation is intuitive and convenient. At the same time, it helps other components (such as the clamping block 180 and the locking mechanism) to cooperate in the same direction, improving the overall coordination and stability of the structure.

[0109] Since the slide rail 111 is aligned with the electric cylinder 160, the movable housing 130 can slide along the natural installation direction of the electric cylinder 160, avoiding angular deviations or interference during disassembly and assembly. Operators can more intuitively and linearly advance or pull out the electric cylinder 160, significantly reducing positioning time and error rate.

[0110] The slide rails 111 arranged in the same direction can provide a stable and consistent linear guide reference for the movable housing 130, avoid lateral offset or vibration, ensure that the electric cylinder 160 is evenly stressed and accurately positioned at both ends during installation, and improve the mechanical precision and dynamic stability of the overall system.

[0111] In at least one embodiment of this application, the mounting structure 100 of the electric actuator further includes:

[0112] A clamping block 180 is disposed at the end of the electric cylinder 160 away from the movable housing 130;

[0113] A fixing plate 181 is disposed on the mounting surface 110a, and a clamping groove is formed between the fixing plate 181 and the clamping block 180.

[0114] Please refer to Figures 1-6 In this embodiment, when the electric cylinder 160 pushes, the clamping block 180 moves linearly along with the electric cylinder 160 body and gradually approaches the fixing plate 181 on the mounting surface 110a. The clamping block 180 is approximately U-shaped. The clamping block 180 gradually embeds into or adheres to the fixing plate 181, forming a clamping groove structure between the two, clamping the vacuum pipe or glue injection pipe within the clamping groove for closure.

[0115] In at least one embodiment of this application, the clamping block 180 protrudes outward on the side near the fixing plate 181 to form a first abutting arc surface 180a, and the fixing plate 181 protrudes outward on the side near the clamping block 180 to form a second abutting arc surface 181a, with the first abutting arc surface 180a and the second abutting arc surface 181a being disposed opposite to each other.

[0116] The electric cylinder 160 moves to drive the clamping block 180 to move closer to or away from the fixed plate 181, so that the first abutting arc surface 180a moves closer to or away from the second abutting arc surface 181a, thereby closing or opening the pipeline.

[0117] Please refer to Figures 1-6 In this embodiment, the first abutting arc surface 180a is disposed on the side of the clamping block 180 near the fixing plate 181, and is an outwardly protruding curved surface. The second abutting arc surface 181a is disposed on the side of the fixing plate 181 near the clamping block 180, and is also an outwardly protruding curved surface.

[0118] When the electric cylinder 160 advances, it drives the clamping block 180 to move forward, so that the first arc surface gradually approaches the second arc surface. When the electric cylinder 160 retracts, the clamping block 180 moves backward, and the first arc surface gradually moves away from the second arc surface.

[0119] When the two curved surfaces are close together, they can clamp or close the pipe in the clamping groove, such as a vacuum pipe or a resin injection pipe. When the curved surfaces move away from each other, the clamping effect is released, and the pipe is in an open or unobstructed state.

[0120] Compared to flat contact, the arc-shaped structure has the characteristics of self-alignment and automatic self-centering, which can adapt to small tolerances in the outer diameter of the pipe, increase the contact area, prevent clamping offset or missing clamping, enhance the uniform distribution of clamping force, and improve sealing and reliability.

[0121] In at least one embodiment of this application, the mounting structure 100 of the electric actuator further includes:

[0122] Guide plates 182 are disposed on both sides of the clamping block 180 and form guide grooves 182a. The clamping block 180 is located in the guide grooves 182a, and the two sides of the clamping block 180 are respectively attached to the two guide plates 182.

[0123] Please refer to Figures 1-6 In this embodiment, a guide plate 182 is provided at the far end of the electric cylinder 160, and a guide plate 182 is provided on the left and right sides of the clamping block 180 respectively. A gap is left between the two guide plates 182 to form a guide groove 182a.

[0124] The clamping block 180 is placed inside the guide groove 182a, and its two sides are in contact with the left and right guide plates 182. When the electric cylinder 160 pushes the clamping block 180 to move back and forth, it can only move back and forth along a set linear trajectory under the restriction of the guide groove 182a.

[0125] The guide groove 182a serves to limit direction and constrain lateral movement, preventing the clamping block 180 from shifting left or right, tilting or rotating during operation, and ensuring that the arc surface at the front end of the clamping block 180 (used for pipe clamping) is always accurately aligned with the fixing plate 181.

[0126] The clamping block 180 is clamped by the guide plates 182 on both sides, so that it moves precisely along a fixed trajectory in the guide groove 182a, ensuring that the clamping surface is aligned and fits the clamped pipe, which greatly improves the clamping efficiency and effect.

[0127] In at least one embodiment of this application, the mounting structure 100 of the electric actuator further includes:

[0128] A retaining ring 190 is disposed on the mounting surface 110a.
