A containerized shelter for additive and subtractive manufacturing equipment and method of installation

Abstract

This invention provides a containerized modular building (MMB) for additive and subtractive manufacturing equipment and its installation method. The MMB includes an external load-bearing frame, an internal load-bearing frame, three reference supports, three support fine-tuning seats, and at least one set of transport locking assemblies. The three reference supports remain in contact and bear vertical loads in both transport and operational states. In operational state, the transport locking assemblies retract from the internal load-bearing frame, forming a working retraction gap, ensuring that the rigid positioning of the internal load-bearing frame relative to the external load-bearing frame is provided solely by the three reference supports. The three reference supports of this invention remain in contact and bear vertical loads in both transport and operational states. During transport, the transport locking assemblies restrict horizontal displacement and upward movement; during operation, the three reference supports bear the working load and provide positioning, which improves the structural stability of the MMB equipment installation reference and provides stable reference conditions for machining accuracy.

Description

Technical Field

[0001] This invention relates to the field of additive and subtractive manufacturing equipment technology, and more specifically, to a containerized container for additive and subtractive manufacturing equipment and its installation method. Background Technology

[0002] Additive-subtractive manufacturing technology integrates additive manufacturing and subtractive machining processes, enabling on-site repair and remanufacturing of damaged parts. It has significant application value in scenarios such as emergency field repair and shipboard repair at sea. Integrating additive-subtractive manufacturing equipment into a modular container allows for the overall hoisting, transportation, and on-site deployment of the entire processing equipment, overcoming the limitations of traditional additive-subtractive equipment that can only operate in fixed factory locations.

[0003] Existing mobile additive-subtractive manufacturing (ADI) modular container technology has been researched. For example, Chinese patent CN112705955A provides a modular container device for mobile ADI composite manufacturing, which integrates a complete set of ADI equipment such as lasers, powder feeders, and milling and turning composite machines into the main body of the container. The container can be mounted on a container transport vehicle to achieve mobile operation that can be started and stopped at any time. The bottom of the container is equipped with an automatic leveling device to ensure that the container platform is level in uneven ground conditions. The container is equipped with a slide rail-slider structure to allow the various functional equipment to be slidably assembled and disassembled, and is equipped with a lifting device to complete the equipment entry and exit from the container. This solves the problem of mobile operation of ADI equipment in the field to a certain extent. However, in this scheme, the outer frame of the container will undergo elastic deformation during hoisting, road impact, and uneven ground settlement. If the equipment base and various media pipelines are rigidly connected to the outer frame in multiple places, the deformation stress of the frame will be directly transmitted to the precision additive and subtractive manufacturing equipment, introducing deviations in the processing benchmark. Its leveling mechanism only solves the overall attitude leveling of the container and does not isolate the disturbance of the outer frame deformation to the processing benchmark of the inner frame. In addition, the positioning constraints of the transportation working condition and the processing working condition are not decoupled. The equipment needs to be reliably locked and limited during transportation, and additional constraints need to be released during processing. The existing scheme lacks a clear switching structure for transportation locking and working release. If the transportation limiting component remains in contact during processing, it will introduce additional constraints to the inner frame and destroy the stability of the equipment benchmark.

[0004] Chinese patent CN211969672U discloses a marine adaptive additive manufacturing container, which adopts a leveling scheme with telescopic cylinders arranged at the four corners. It relies on tilt sensors to feed back the ship's deck sway signal and drives the cylinders to extend and retract in real time to maintain the container's level, adapting to the swaying conditions of ships at sea. However, this scheme only compensates for the overall attitude of the container and does not consider the elastic deformation of the container frame caused by loads, which restricts the processing accuracy and long-term operational reliability of the precision additive and subtractive manufacturing equipment inside the container. Summary of the Invention

[0005] The problem solved by this invention is that, under conditions of hoisting, transportation, and ground deformation, the deformation of the outer frame of existing mobile modular containers easily transmits disturbances inward to the precision machining reference, making it difficult to simultaneously ensure reliable locking during transportation and high precision stability of the equipment reference during machining.

[0006] To address the aforementioned problems, the present invention provides a container for additive and subtractive manufacturing equipment, comprising an external load-bearing frame, an internal load-bearing frame, three reference supports, three support fine-tuning seats, and at least one set of transport locking components;

[0007] The external load-bearing frame has hoisting nodes and a continuous load-bearing path;

[0008] The built-in load-bearing frame is used to fix and install the additive and subtractive materials equipment, and is spaced apart from the side wall enclosure structure of the external load-bearing frame;

[0009] The three reference supports are arranged in a triangle in the horizontal plane and are respectively set between the three reference nodes of the built-in load-bearing frame and the bottom of the external load-bearing frame; each reference support includes a spherical positioning element fixed to the reference node and a positioning seat set on one side of the external load-bearing frame; the three reference supports remain in contact and bear vertical loads in both the transportation and working states.

[0010] The three support fine-tuning seats respectively support the positioning seats of the three reference supports, and each support fine-tuning seat has a height adjustment mechanism and a locking mechanism;

[0011] In the transport state, the transport locking assembly horizontally presses, upperally presses, and horizontally stops the built-in load-bearing frame relative to the external load-bearing frame, and does not provide a vertical top support below the built-in load-bearing frame; in the working state, the transport locking assembly retracts from the built-in load-bearing frame and forms a working retraction gap, so that the rigid positioning of the built-in load-bearing frame relative to the external load-bearing frame is provided only by the three reference supports.

[0012] Preferably, the external load-bearing frame includes a bottom main beam, a top beam, four corner columns, and lifting corner pieces fixed to the nodes of the four corner columns. The bottom main beam, the top beam, and the four corner columns are connected to form a continuous load-bearing system. The lifting corner pieces are used to connect the lifting slings and bear the lifting load and transportation load.

[0013] Preferably, the positioning seat of the first reference support is a conical positioning seat, the positioning seat of the second reference support is a V-shaped positioning groove with its groove axis arranged along the line connecting the first reference support and the second reference support, and the positioning seat of the third reference support is a planar positioning seat; when the three spherical positioning elements are in contact with their respective positioning seats, the first reference support, the second reference support, and the third reference support provide three, two, and one independent constraints, respectively. The second reference support allows slight sliding along the groove axis of the V-shaped positioning groove, and the third reference support allows slight sliding along the planar direction of the planar positioning seat.

[0014] Preferably, the projection of the combined center of gravity of the additive / subtractive material device and the built-in load-bearing frame under each working condition is located within the support triangle formed by the three reference supports.

[0015] Preferably, the transport locking assembly includes a transport locking seat fixed to the bottom main beam of the external load-bearing frame, a horizontal pressing member installed on the transport locking seat and capable of horizontal movement, a mating locking block fixed to the built-in load-bearing frame, an upper pressing member, and a horizontal stop member; in the transport state, the horizontal pressing member abuts against the side of the mating locking block to provide horizontal pressing, the upper pressing member presses against the upper surface of the mating locking block, the horizontal stop member restricts the horizontal displacement of the built-in load-bearing frame, and the transport locking assembly does not push against the built-in load-bearing frame from below.

[0016] Preferably, the horizontal clamping component is a locking wedge, the wedge angle of the locking wedge is arranged in the horizontal section and its contact surface extends in the vertical direction, and the locking wedge is driven by a lead screw or a manual adjustment component; the working retraction clearance is 2mm~5mm.

[0017] Preferably, the transport locking assembly further includes an anti-return retention structure, which includes a backstop pin, a pawl, a friction locking element, or a self-locking threaded pair, for preventing the horizontal clamping element, the upper clamping element, and the horizontal stop from retracting and thus preventing them from automatically returning to a position in contact with the built-in support frame.

[0018] Preferably, the system further includes a status detection component and a controller; the status detection component is used to detect the retraction status of the horizontal clamping component, the upper clamping component, and the horizontal stop component, as well as the contact or bearing status of the three reference supports and the locking status of the support fine-tuning seat; the controller is signal-connected to the status detection component and is configured to prohibit the output of a machining enable signal when the transport locking assembly is not retracted, the three reference supports are not in contact, or the support fine-tuning seat is not locked.

[0019] Preferably, it further includes a leveling support leg, which is connected to the bottom main beam of the external load-bearing frame and is provided with a height adjustment mechanism and a stabilizing foot for coarse adjustment after the external load-bearing frame is in place; the support fine-tuning seat is used for fine adjustment of the built-in load-bearing frame when the transport locking assembly is completely retracted and the material addition and subtraction equipment stops processing.

[0020] Preferably, the device further includes a reference verification component, which comprises three non-collinear standard spheres fixed to the built-in support frame, the three standard spheres maintaining a defined geometric relationship with the device mounting surface.

[0021] The present invention also provides an installation method for a containerized modular building for additive and subtractive manufacturing equipment, the containerized modular building for additive and subtractive manufacturing equipment described above, comprising:

[0022] Step S1: Position the external load-bearing frame, and have the leveling outriggers take over the load of the cabin and complete the overall coarse adjustment of the external load-bearing frame.

[0023] Step S2: Release the upper clamping member, retract the horizontal clamping member and the horizontal stop member to the working position, and confirm that the working retraction gap is formed between the transport locking assembly and the built-in bearing frame;

[0024] Step S3: Under the condition that all the transport locking components have been retracted and the material addition and subtraction equipment has stopped processing, the three support fine-tuning seats are adjusted alternately in small amounts to adjust the level of the built-in bearing frame, and the height of the support fine-tuning seat is locked after the adjustment is completed.

[0025] Step S4: Check the contact state, preload state, and working clearance of the three reference supports;

[0026] Step S5: The probe of the additive and subtractive material equipment measures the center coordinates of the three non-collinear standard spheres fixed to the built-in bearing frame and compares them with the records during the first assembly. After rigid body registration, the overall offset, residual of each sphere and change in distance between spheres are checked. If qualified, the machining enable signal is output.

[0027] It is prohibited to adjust the three reference supports before the transport locking assembly has been disengaged.

[0028] Preferably, if the inspection result of step S5 exceeds the allowable range, first check the contamination of the positioning surface, the residual contact of the transport locking assembly, and if the container is equipped with a through-cabin interface box and cross-frame pipeline, check the tension of the cross-frame pipeline, and then adjust the support fine-tuning seat or perform machine tool calibration on the additive and subtractive material equipment.

[0029] Compared with the prior art, the container and installation method for additive and subtractive manufacturing equipment described in this embodiment of the invention have the following beneficial effects:

[0030] 1) The three reference supports are arranged in a triangle, maintaining contact and bearing vertical loads in both transport and working states; during transport, the transport locking assembly restricts horizontal displacement and upward movement, while during operation, the three reference supports bear the working load and form a positioning system, which helps to improve the structural stability of the installation reference of the container equipment.

[0031] 2) The transport locking component achieves decoupling of constraints between transport and working conditions: during transport, the built-in load-bearing frame is horizontally pressed, top pressed, and horizontally stopped; in the working state, it is disengaged from the built-in load-bearing frame and forms a working retraction gap, so that the rigid positioning of the built-in load-bearing frame is provided only by three reference supports, avoiding or reducing the introduction of additional rigid constraints by the transport locking component in the working state.

[0032] 3) The external load-bearing frame is coarsely adjusted by using leveling legs, and the internal load-bearing frame is finely adjusted by using the support fine-adjustment seat in combination with three reference supports arranged in a triangle. Under the condition that the fine-adjustment seat is locked and the three points are in contact, it is beneficial to maintain the horizontal installation reference of the material addition and subtraction equipment, and the directional micro-slip of the second and third reference supports reduces the over-constraint caused by the deformation of the outer frame bottom frame, providing stable reference conditions for processing accuracy.

[0033] 4) Configure a status detection component and controller interlocking mechanism to prohibit the output of processing enable when the transport locking component is not retracted, the three reference supports are not in contact, or the support fine-tuning seat is not locked, thereby reducing the risk of the equipment starting processing in a non-standard positioning state.

Detailed Implementation

[0046] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Without conflict, the technical features of the embodiments of the present invention can be combined with each other.

[0047] Example 1

[0048] like Figure 1-10 As shown, this embodiment provides a containerized modular unit for additive and subtractive manufacturing equipment, suitable for overall hoisting, transportation and relocation, and on-site deployment and processing, including:

[0049] The external load-bearing frame 1, the internal load-bearing frame 2, three reference supports 3, 4, and 5, three support fine-tuning seats 10, and at least one set of transport locking components;

[0050] The external load-bearing frame 1 has hoisting nodes and a continuous load-bearing path;

[0051] The built-in load-bearing frame 2 is used to fix and install the additive and subtractive materials equipment, and is spaced apart from the side wall enclosure structure of the external load-bearing frame 1.

[0052] The three reference supports 3, 4, and 5 are arranged in a triangle in the horizontal plane and are respectively set between the three reference nodes of the built-in load-bearing frame 2 and the bottom of the external load-bearing frame 1; each reference support includes a spherical positioning component fixed to the reference node and a positioning seat set on one side of the external load-bearing frame 1; the three reference supports 3, 4, and 5 maintain contact and bear vertical loads in both the transportation and working states;

[0053] The three support fine-tuning seats 10 respectively support the positioning seats of the three reference supports 3, 4, and 5, and each support fine-tuning seat 10 has a height adjustment mechanism and a locking mechanism;

[0054] In the transport state, the transport locking assembly horizontally presses, upperally presses, and horizontally stops the built-in load-bearing frame 2 relative to the external load-bearing frame 1, without providing a vertical top support below the built-in load-bearing frame 2; in the working state, the transport locking assembly retracts from the built-in load-bearing frame 2 to form a working retraction gap, so that the rigid positioning of the built-in load-bearing frame 2 relative to the external load-bearing frame 1 is provided only by the three reference supports 3, 4, and 5.

[0055] This invention arranges three reference supports 3, 4, and 5 in a triangle, maintaining contact and bearing vertical loads in both transport and working states. During transport, the transport locking assembly restricts horizontal displacement and upward movement; during working states, the three reference supports 3, 4, and 5 bear the working load and provide positioning, which helps improve the structural stability of the container equipment installation reference. The transport locking assembly achieves decoupling of constraints between transport and working states: during transport, it horizontally presses, presses, and horizontally stops the built-in load-bearing frame 2; during working states, it disengages from the built-in load-bearing frame 2 and forms a working retraction gap, so that the rigid positioning of the built-in load-bearing frame 2 is provided only by the three reference supports 3, 4, and 5, avoiding or reducing the introduction of additional rigid constraints by the transport locking component during working states.

[0056] As an example, the external load-bearing frame 1 includes a continuous bottom main beam and a top beam, and four corner columns located between the bottom main beam and the top beam. The four corner columns are connected to the bottom main beam and the top beam through welding or structural connectors to form a closed frame. Lifting corner fittings are fixed to the corner column nodes. As the main load-bearing base of the shelter, the external load-bearing frame 1 forms a continuous load-bearing path, bearing the load of the shelter after lifting, transportation, and landing. The internal load-bearing frame 2 does not participate in maintaining the shape of the shelter, thereby reducing the transfer of deformation of the external frame to the internal frame and helping to maintain the stability of the equipment installation benchmark. The lifting slings are only connected to the designated lifting nodes. The equipment bed and the internal load-bearing frame 2 do not act as structural tie rods connecting the lifting points on both sides, the side walls, or the top frame.

[0057] As an example, a circumferential gap δ is reserved between the built-in load-bearing frame 2 and the side wall enclosure and the top enclosure. δ is determined by the sum of the maximum elastic deformation of the outer frame under the impact conditions of lifting and transportation and the assembly tolerance. No rigid parts connecting the inner frame and the enclosure structure are set in the gap area, and it is permissible to set limit parts that only function under transportation conditions and retract with the transportation locking components under working conditions.

[0058] As an example, the built-in load-bearing frame 2 is used to fix and install the additive / subtractive equipment, and is spaced apart from the side wall enclosure structure of the external load-bearing frame 1. That is, the built-in load-bearing frame 2 maintains a gap with the side and top walls of the cabin. The weight of the equipment itself is transferred to the bottom frame of the external load-bearing frame 1 via the bottom reference support. The built-in load-bearing frame 2 does not act as a load-bearing component to maintain the shape of the external load-bearing frame 1. This arrangement avoids a rigid connection between the enclosure panel and the built-in load-bearing frame 2, reducing deformation of the external load-bearing frame 1 and its transfer to the built-in load-bearing frame 2 through the enclosure structure. During hoisting, the weight of the equipment and the built-in load-bearing frame 2 remains a load on the external load-bearing frame 1, but the built-in load-bearing frame 2 does not participate in maintaining the shape of the external cabin. Preferably, the transport locking seat 6 is arranged at the node of the main beam or reinforcing beam of the bottom frame, which helps to distribute concentrated loads and avoid excessive local stress on the thin enclosure panel.

[0059] As a preferred example, the built-in load-bearing frame 2 adopts a box beam or a welded frame with stress relief treatment. Its equipment mounting surface and three reference nodes are machined. The three nodes are arranged in a triangle on the plane. The projection of the combined center of gravity of the added / subtracted equipment and the built-in load-bearing frame 2 under various normal working conditions is located within the support triangle formed by the three reference supports. This setting is beneficial to improving support stability and reducing the risk of overturning. The support spacing and the cross section of the reference nodes are determined according to the equipment mass, center of gravity and machining torque.

[0060] The preload of the three reference supports is provided by the weight of the additive / subtractive material equipment and the built-in load-bearing frame 2. If necessary, preload elements without introducing additional positioning constraints are added. Under transportation conditions, the vertical reaction force of each support is calculated by multiplying the equipment's weight by the transportation impact coefficient, ensuring that each support remains in compressed contact and does not detach under the most unfavorable conditions. The vertical load is always borne by the three reference supports, while the horizontal impact load is borne by the transportation locking assembly; therefore, the locking action does not change the three-point contact relationship. As an example, the first reference support 3 consists of a spherical positioning component of the built-in load-bearing frame 2 and a tapered positioning seat on the bottom frame side of the external load-bearing frame 1; the second reference support 4 consists of a spherical positioning component and a V-shaped positioning groove, with the axis of the V-shaped positioning groove set along the line connecting the nodes of the first reference support 3 and the second reference support 4; the third reference support 5 consists of a spherical positioning component and a planar positioning seat. With all contact surfaces maintaining contact, the first reference support 3, the second reference support 4, and the third reference support 5 provide 3, 2, and 1 independent constraints, respectively, jointly constraining the six rigid body degrees of freedom of the built-in load-bearing frame 2. The second reference support 4 allows for slight sliding along the axis of the V-shaped positioning groove, and the third reference support 5 allows for slight sliding along the plane of the planar positioning seat. This arrangement allows the conical seat, the V-shaped groove, and the planar seat to jointly constrain the six rigid body degrees of freedom. At the same time, the second reference support 4 and the third reference support 5 allow for slight directional sliding, which avoids over-constraint and reduces the additional stress on the built-in load-bearing frame 2 caused by deformation or thermal displacement of the external frame.

[0061] As an example, the cone half-angle of the conical positioning seat is 45° to 60°, the groove half-angle of the V-shaped positioning groove is 45° to 60°, and the spherical radius is determined according to the allowable value of contact stress; the spherical positioning component of the reference support adopts a replaceable hardened wear-resistant component, and the spherical radius, contact stress, positioning seat body strength and preload are calculated based on the weight of the material addition and subtraction equipment, processing load and transportation load.

[0062] As a preferred example, the positioning seats of the three reference supports are respectively installed on the support fine-tuning seat 10. The support fine-tuning seat 10 has a height adjustment mechanism and a locking mechanism, and can be equipped with a bearing wedge block and an adjusting screw structure. After the support fine-tuning seat 10 is adjusted, what is locked is the height of the support fine-tuning seat itself, and will not lock the slight slippage allowed by the second reference support 4 and the third reference support 5. In the working state, the three support fine-tuning seats 10 can only be adjusted in small amounts alternately after the transport locking components have been completely retracted and the material addition and subtraction equipment has stopped processing, so as to adjust the levelness of the built-in bearing frame 2. After the adjustment is completed, check the contact state, preload state and locking state of the three reference supports and the support fine-tuning seat 10.

[0063] This setting allows the support fine-tuning seat 10 to finely adjust the built-in bearing frame 2 and lock its own height after adjustment, without locking the slight sliding degrees of freedom of the second reference support 4 and the third reference support 5, thereby maintaining a reasonable constraint state of the three-point support while achieving level adjustment.

[0064] As an example, the transport locking assembly is configured in multiple sets, arranged on adjacent sides or diagonally opposite positions of the built-in load-bearing frame 2. Each set of transport locking assemblies includes a transport locking seat 6 fixed to the bottom frame of the external load-bearing frame 1, a horizontal clamping member 7 that moves in and out along the horizontal guide groove, a mating locking block 8 fixed to the built-in load-bearing frame 2, an upper clamping member, and a horizontal stop member 9. This arrangement can limit the horizontal displacement and upward movement of the built-in load-bearing frame 2 without exerting a pushing effect on it or changing the contact relationship of the three-point support.

[0065] Preferably, the horizontal clamping member 7 is a locking wedge, with its wedge angle arranged within a horizontal section and its contact surface extending vertically. After the horizontal clamping member 7 is pushed forward, it presses against the side of the mating locking block 8 to achieve horizontal clamping. The upper clamping member presses against the upper surface of the mating locking block 8, and the horizontal stop member 9 is used to limit the horizontal displacement of the built-in load-bearing frame 2 during transportation. The three reference supports continuously bear the vertical load, and the transportation locking assembly does not push the built-in load-bearing frame 2 from below. The transportation locking action does not change the contact relationship between the three reference supports. As an example, the wedge ratio is 1:10 to 1:20 with an adjusting screw, the adjustment stroke is not less than ±3mm, and the resolution meets the requirements for fine adjustment of the horizontality. The locking mechanism is a locking nut with an anti-loosening washer or a clamping screw. After locking, only the position of the wedge block, i.e., the height of the support point, is fixed. The contact pair between the spherical part and the V-groove and the flat seat is not forced, so the slight directional slippage is not locked.

[0066] As an example, the horizontal clamping component 7 is driven by a lead screw or manual adjustment mechanism and is equipped with a mechanical anti-loosening or anti-reverse structure. This configuration allows the horizontal clamping component 7 to maintain the locking force purely mechanically, making it less prone to loosening under bumpy transportation conditions and eliminating reliance on motors or hydraulic systems for continuous pressure maintenance. After retracting from the working position, the anti-reverse retention structure prevents the horizontal clamping component 7, the upper clamping component, and the horizontal stop component 9 from rebounding and contacting the internal load-bearing frame due to vibration, avoiding the introduction of additional constraints to the internal load-bearing frame 2, ensuring the unique datum status of the three reference supports, and improving the reliability of container deployment and processing.

[0067] As an example, the transport locking assembly is also equipped with an anti-return retention structure, which can be a stop pin, pawl, friction lock, or self-locking thread pair, used to prevent the aforementioned components from automatically resetting and contacting the built-in bearing frame 2 after the horizontal clamping member 7, the upper clamping member, and the horizontal stop member 9 have been retracted. When it is a stop pin, it is inserted into the pin hole between the horizontal clamping member 7 and the transport locking seat 6 after retraction; when it is a pawl or friction lock, it is located on the screw or guide groove side of the horizontal clamping member 7; when it is a self-locking thread pair, a self-locking thread with a helix angle smaller than the friction angle is used.

[0068] As an example, during transport, the first reference support 3, the second reference support 4, and the third reference support 5 maintain contact and bear the weight of the equipment and the vertical transport load; the transport locking assembly restricts the horizontal displacement and upward movement of the built-in load-bearing frame 2. The positioning components, pre-tensioning components, transport locking seat 6, and horizontal stop 9 are all checked according to actual transport conditions; the distribution of horizontal load between the reference supports and the transport stop should take into account the fit clearance and connection rigidity. The transport locking assembly relies on the mechanical structure to maintain the locking state, without solely relying on the drive motor or hydraulic system to continuously output locking force.

[0069] During transportation, the three reference supports 3, 4, and 5 continuously bear the vertical load, and the transportation locking assembly restricts horizontal displacement and upward movement, forming a reliable transportation fixation; the locking state is maintained by the mechanical structure, which can avoid the loss of locking force due to the failure of the drive motor or hydraulic system, thus improving transportation safety.

[0070] As an example, when deploying the modular shelter on-site, the upper clamping components should be released first, provided that the external load-bearing frame 1 has been leveled and stably supported by the outriggers 13. Then, the horizontal clamping components 7 and the horizontal stop components 9 should be moved back to the working position to confirm that all transport locking components are disengaged from the built-in load-bearing frame 2, forming a working retraction gap.

[0071] The working retraction clearance h is determined by the working fine-tuning displacement Δ1, thermal displacement Δ2, vibration displacement Δ3, and assembly deviation Δ4, i.e., h ≥ Δ1 + Δ2 + Δ3 + Δ4, and is taken as 2mm to 5mm. After deployment, it is measured at the three transport locking nodes using a feeler gauge or displacement detection piece. This clearance needs to cover the combined displacement envelope of the working fine-tuning displacement, thermal displacement, vibration displacement, and assembly deviation. After confirming the retraction of the locking assembly, adjust the three support fine-tuning seats 10 as needed; after adjustment, recheck the contact state of the three reference supports, the locking state of the support fine-tuning seats 10, and the working retraction clearance. In the working state, the transport locking assembly retracts from the built-in load-bearing frame 2 and forms the working retraction clearance, so that the rigid positioning of the built-in load-bearing frame 2 relative to the external load-bearing frame 1 is provided only by the three reference supports.

[0072] This configuration allows the transport locking assembly to fully retract and form a working retraction gap in the working state, making the three reference supports 3, 4, and 5 the sole source of rigid positioning for the inner frame, thus avoiding the introduction of additional constraints by the transport locking components. The retraction gap covers working fine-tuning, thermal displacement, vibration, and assembly deviations, which helps to ensure that the inner frame is not interfered with by the transport locking components in the working state.

[0073] As an example, the status detection component 12 detects the retraction status of the horizontal clamping component 7, the upper clamping component, and the horizontal stop component 9, and simultaneously detects the contact or bearing status of the three reference supports, as well as the locking status of the support fine-tuning seat 10. The controller receives the signal from the status detection component 12. When the transport locking assembly is not fully retracted, the three reference supports are not kept in contact, or the support fine-tuning seat 10 is not locked, the controller prohibits the output of the processing enable signal.

[0074] As an example, the status detection element 12 includes a proximity switch or limit switch for detecting the retraction of the horizontal clamping element 7, the upper clamping element, and the horizontal stop 9 into place; a force measuring element, pressure / strain element, or contact displacement element for detecting the contact or load-bearing state of the three reference supports; and a locking displacement switch or torque detection element for detecting the locking state of the fine-tuning seat.

[0075] As an example, the leveling outrigger 13 is connected to the bottom main beam of the external load-bearing frame 1 via a hinge or fixed seat; the leveling outrigger 13 has a height adjustment mechanism in the form of a screw or hydraulic cylinder and a stabilizing foot, used for the overall coarse adjustment of the external load-bearing frame 1 after the container is placed; the support fine-tuning seat 10 is used for the fine adjustment of the internal load-bearing frame 2; this setup uses the leveling outrigger 13 to perform the overall coarse adjustment of the external load-bearing frame 1, and the support fine-tuning seat 10 to perform the fine adjustment of the internal load-bearing frame 2, with coarse and fine adjustments performed in layers to avoid mutual interference; it is forbidden to adjust the three-point reference when the transport lock is not removed, which can prevent forced adjustment from causing structural deformation or positioning inaccuracy.

[0076] As an example, a reference verification element 14 is provided on the built-in support frame 2. The reference verification element 14 includes three non-collinear standard spheres fixed to the built-in support frame 2, and the three standard spheres maintain a defined geometric relationship with the equipment mounting surface. This setup uses the reference verification element 14 to provide a measurable reference after transfer. By comparing the coordinates of the standard spheres and the distance between the spheres, the relative relationship between the equipment measurement system and the inner frame reference can be verified, providing a basis for whether to correct the workpiece positioning offset.

[0077] During the initial assembly phase, the coordinates of the centers of the three standard spheres and the distance between them are recorded, along with the geometric inspection results of the equipment, forming a deployment verification benchmark. After the modular shelter is transported and positioned, once the equipment reaches the verification conditions in its thermal state, the center coordinates of the three standard spheres are collected using the built-in probes of the subtractive material equipment. The measured data is then compared with the initial assembly records. This measurement result characterizes the relative position of the equipment's measurement system with respect to the built-in load-bearing frame 2 benchmark component. However, it cannot detect the absolute attitude of the entire modular shelter relative to the ground. If it is necessary to measure the overall attitude of the modular shelter relative to the ground, an independent external benchmark or tilt sensor needs to be added.

[0078] As an example, rigid body registration calculations are performed on the standard spherical coordinate differences to check the overall offset, residuals of each sphere, and changes in the distance between spheres. Only when all non-rigid body residual indicators and necessary geometric inspections of the equipment are qualified is it permissible to correct the workpiece positioning offset according to the CNC system support method. Coordinate offset correction cannot replace the whole-machine calibration of machine tool guideway straightness, inter-axis perpendicularity, and spindle status. Through rigid body registration and residual checks, the overall offset and non-rigid body deformation can be distinguished, avoiding the misuse of coordinate offset compensation to replace machine tool geometric accuracy calibration. When deviations are found, the positioning surface, residual contact of transport locking components, and pipeline tension should be checked in sequence, which is conducive to quickly locating the source of the problem. When the test results are out of tolerance, priority should be given to checking the positioning surface contamination and residual contact of transport locking components. If the container cabin is also equipped with a through-cabin interface box 26 and cross-frame pipelines, the reaction force at the end of the flexible connection section 28 and the joint leakage status should also be checked. Then, the support fine-tuning seat 10 should be adjusted or the whole-machine tool calibration of the equipment with added or subtracted materials should be carried out.

[0079] The present invention also provides a method for installing a containerized modular unit for additive and subtractive manufacturing equipment, comprising:

[0080] Step S1: Position the external load-bearing frame 1, and have the leveling outrigger 13 take over the load of the cabin and complete the overall coarse adjustment of the external load-bearing frame 1.

[0081] Specifically, the leveling leg 13 is connected to the bottom main beam of the external load-bearing frame 1 by a hinge or fixed seat, and the external load-bearing frame 1 is made to reach the specified level by using a height adjustment mechanism in the form of a screw or hydraulic cylinder and a stabilizing leg.

[0082] Step S2: Release the upper clamping component, and retract the horizontal clamping component 7 and the horizontal stop component 9 to the working position, confirming that a working retraction gap is formed between the transport locking assembly and the built-in bearing frame 2;

[0083] Step S3: With all the transport locking components removed and the material addition / subtraction equipment stopped processing, the three support fine-tuning seats 10 are adjusted alternately in small amounts to adjust the level of the built-in bearing frame 2, and the height of the support fine-tuning seats 10 is locked after the adjustment is completed.

[0084] During the adjustment process, the three reference supports remain in contact. The second reference support 4 is allowed to slide slightly along the axis of the V-shaped positioning groove, and the third reference support 5 is allowed to slide slightly along the plane of the planar positioning seat.

[0085] Step S4: Check the contact status, preload status, and working clearance of the three reference supports. The contact or load-bearing status of the three reference supports, the locking status of the support fine-tuning seat 10, and the disengagement status of the transport locking assembly can be detected by the status detection component 12.

[0086] Step S5: The probe of the additive / subtractive material equipment measures the center coordinates of the three non-collinear standard spheres fixed to the built-in bearing frame 2 and compares them with the records during the first assembly. After rigid body registration, the overall offset, residuals of each sphere and changes in the distance between the spheres are checked. After passing the check, the processing enable is output.

[0087] Specifically, it is prohibited to adjust the three reference supports before the transport locking components have been retracted. The controller only grants the support fine-tuning seat 10 adjustment permission after the status detection component 12 confirms that all transport locking components have been retracted and the measured working retraction clearance is qualified; this permission is separate from the processing enable, preventing adjustment before retraction from a control perspective.

[0088] As an example, if the inspection results of step S5 exceed the allowable range, first check for contamination of the positioning surface and residual contact of the transport locking components; if the container cabin is also equipped with a through-cabin interface box 26 and cross-frame pipelines, the end reaction force of the flexible connection section 28 and the joint leakage status should also be checked; then adjust the support fine-tuning seat 10 or perform machine tool calibration on the additive and subtractive equipment.

[0089] As an example, load detection or contact detection devices are temporarily placed at the three reference support nodes to confirm that the three reference supports maintain contact before and after transport locking; the contact and anti-loosening status of the horizontal clamping component 7, the upper clamping component, and the horizontal stop component 9 are checked during transport operation; the working condition is checked to ensure that all transport locking components are retracted into place, and the working retraction clearance is measured. After releasing the transport locking components, the fine-tuning seat 10 of the operating support is used for fine adjustment, and the levelness, three-point support contact, and locking status before and after adjustment are recorded; simply checking that the drive mechanism has reached the required stroke does not equate to actual support contact and clearance being qualified.

[0090] Under the premise that the equipment load, placement conditions and thermal state of the equipment remain consistent, record the coordinates of the center of the standard sphere, the distance between the spheres, and the rigid body registration residual before and after the transport of the container, and record the time taken from placement to meeting the conditions for processing permission; the reset error is judged based on the accuracy index of the corresponding material addition and subtraction equipment itself, without preset fixed micron-level accuracy thresholds or fixed time.

[0091] Example 2

[0092] Based on Example 1, an environmental protection structure can be added as an optional additional implementation method. This additional implementation method does not affect the positioning reference relationship described in Example 1.

[0093] Specifically, in Embodiment 1, the external load-bearing frame 1 is internally divided into a processing compartment and a service compartment by partitions. The internal load-bearing frame 2 and the additive / subtractive material equipment are located in the processing compartment. The air handling unit 15 is installed in the service compartment and is connected to the pressure equalization air supply chamber 16 at the top or upper side of the processing compartment via air supply ducts. Thermal bridge partitions 17 are installed in the door frame or corner column lining, local heating elements 18 are installed on the inner metal surface of the thermal bridge partitions 17, temperature sensors 19 are installed on easily condensing surfaces, and humidity sensors 20 are installed at the air supply and return positions of the processing compartment. A process trap hood 21 is installed in the processing area, and independent filter units 22 and process exhaust fans 23 are sequentially installed on the process exhaust path. A treatment air supply assembly 24 is installed on the air supply path, and its outlet is connected to the air handling unit 15 or the clean side of the processing compartment. Differential pressure sensors 25 are respectively installed between the processing compartment and the outside of the compartment, and between the process trap hood 21 and the processing compartment. The trans-chamber interface box 26 is fixed to the external load-bearing frame 1. The two ends of the cross-frame pipeline are fixed by the outer fixing clip 27 and the inner fixing clip 29 respectively, and a flexible connection section 28 is set in the middle. The air duct is provided with a flexible duct compensation section 30. The water receiving tray 31 is respectively set in the air handling unit 15 and / or the trans-chamber interface box 26.

[0094] This setup integrates environmental protection structures such as air handling, anti-condensation, process exhaust, and flexible inter-cabin connections into the container of Embodiment 1. It can provide a stable temperature and humidity environment and clean process exhaust conditions for the additive and subtractive equipment, while reducing the additional constraints of pipelines on the built-in load-bearing frame 2 through flexible connections.

[0095] As an example, the air handling unit 15 is installed in the service compartment area of ​​the cabin and includes a filter section, cooling and dehumidifying coils, a water tray 31 and drain pipes, a reheat section, a blower, and matching regulating valves. Return air from the processing compartment and pre-treated makeup air are connected to the air handling unit 15; the air is dehumidified by the cooling and dehumidifying coils, and then sent to the equalizing air supply chamber 16 after the supply air temperature is adjusted by the reheat section. Through cooling, dehumidification, and reheating, the supply air temperature and humidity can be regulated to meet the constant temperature and humidity requirements of the processing compartment. In dry conditions where a lower humidity limit needs to be maintained, a controlled humidification section can be added. When the humidity conditions are met, the humidification section does not operate, adapting to the requirement of maintaining the lower humidity limit under dry conditions.

[0096] As an example, the pressure equalization air supply chamber 16 is located in the upper or upper side of the processing chamber, and the air outlet is equipped with a flow equalization plate and a diffuser plate; the return air outlet is located in the clean return air area outside the equipment enclosure, independent of the process collection air outlet. The water collection tray 31 is equipped with a drainage slope and drainage structure, and the drain outlet is equipped with a water seal adapted to the pressure difference and an anti-backflow structure; condensate is discharged outwards and does not flow into the processing chamber. The pressure equalization air supply chamber 16 facilitates uniform air supply, and separating the return air outlet from the process collection air outlet can prevent dust-laden airflow from entering the environmental circulation; the water collection tray 31 and the drainage structure can centrally discharge condensate and prevent condensate from entering the processing chamber. The cooling dehumidification coil and water collection tray 31 are areas where condensation is permissible and are not included in the assessment of the minimum surface temperature of the enclosure and equipment.

[0097] As an example, temperature sensors 19 are arranged on condensation-prone surfaces such as the inner side of the door frame, the inner lining of the corner posts, and the inner side of the inter-cabin interface box 26; local heating elements 18 can be attached or clamped onto the inner metal surface of the thermal bridge partition 17. By arranging temperature sensors 19 on condensation-prone surfaces and setting local heating elements 18, local anti-condensation measures can be implemented for thermal bridge nodes; independent temperature limiting and over-temperature protection can improve heating safety.

[0098] As an example, the local heating element 18 can be a PTC heating element or an electric heating strip, which is in contact with the controlled metal surface through a thermal pad, and is insulated on the outside. It is equipped with independent temperature limit and over-temperature protection, and it is prohibited to rely on heating the low-temperature process medium to replace the enclosure insulation and vapor barrier.

[0099] As an example, humidity sensor 20 is arranged at representative measuring points in the supply and return air of the processing chamber; the controller collects signals from temperature sensor 19 and humidity sensor 20 to calculate the highest dew point T. d max The lowest surface temperature T was obtained from each temperature sensor 19. s min When T s min - T d max If the temperature falls below the preset safety margin, the controller prioritizes dehumidification and simultaneously activates the local heating element 18 at the corresponding thermal bridge node, adjusting reheat and air supply conditions as needed. Control based on dew point margin allows for timely dehumidification and local heating when the surface temperature approaches the dew point, reducing the risk of condensation. It also considers both make-up air volume and pressure differential to prevent the processing chamber from losing its predetermined pressure differential due to anti-condensation measures.

[0100] As an example, the environmental circulation air route consists of the clean return air from the processing chamber, the air handling unit 15, the pressure equalization air supply chamber 16, and the processing chamber forming a closed loop; the process exhaust air route consists of the process trap hood 21, the independent filter unit 22, the process exhaust fan 23, and the external exhaust port; the dust-laden process exhaust air does not flow back into the air handling unit 15 and does not share the filter chamber with the environmental return air. The process trap hood 21 can utilize the existing outer cover of the equipment to form a semi-enclosed hood, or it can be equipped with additional enclosures, baffles, and directional trapping ports; the air supply to the trap hood is taken from the clean area of ​​the processing chamber, and the suction direction avoids the protective gas nozzle and the powder delivery bundle. The independent filter unit 22 is selected according to the physical properties of the smoke and dust; the process exhaust fan 23 is arranged downstream of the filter, so that the trapping pipeline and the section before the filter are under negative pressure relative to the processing chamber; the filter is equipped with differential pressure detection, and the effectiveness of trapping is verified by airflow and hood opening status, and cannot be judged solely by the fan operation signal. This arrangement separates the environmental circulation air path from the process exhaust air path, which can prevent dust-laden exhaust air from entering the air handling unit 15; the process exhaust fan 23 is arranged downstream of the filter, which helps to keep the collection pipeline and the front section of the filter under negative pressure, reducing dust leakage.

[0101] As an example, the differential pressure sensor 25 is equipped with two sets of pressure tapping channels: one set measures the pressure difference between the processing chamber and the outside, and the other set measures the pressure difference between the process trap hood 21 and the processing chamber; the working objective is the positive pressure p inside the chamber relative to the outside. 舱 -p 外 >0, the negative pressure p of the capture hood relative to the processing chamber 罩 -p 舱 <0. By controlling the positive pressure of the processing chamber and the negative pressure of the collection hood through two sets of differential pressure sensors 25, the positive pressure of the processing chamber can be maintained while the relative negative pressure of the collection hood is ensured; the feedforward adjustment of the air supply and the closed-loop regulation are conducive to maintaining a stable differential pressure when the exhaust air changes.

[0102] The differential pressure tap must be kept away from the supply air jet, and the external pressure tap must be equipped with a rainproof and windproof cover. The make-up air assembly 24 includes a filter, an adjustable fan or damper, and a pretreatment unit. The make-up air output is adjusted forward according to the process exhaust air volume, and then corrected in a closed loop according to the pressure difference inside the chamber. The ambient air volume is used for the uniformity of temperature and humidity inside the chamber and does not include the clean fresh air for compensating for the exhaust air. The steady-state flow balance of the system comprehensively considers the fresh air input, process gas release, process exhaust air, and chamber leakage, and maintains the pressure difference by relying on the actual measurement feedback of the differential pressure sensor 25.

[0103] As an example, the transom interface box 26 is fixed to the external load-bearing frame 1 or its associated secondary enclosure structure; there is no through rigid mounting base between the transom interface box 26 and the internal load-bearing frame 2. This arrangement separates the wet medium from the electrical area, reducing leakage and electrical safety risks; the absence of a through rigid mounting base reduces the transmission of deformation of the external load-bearing frame 1 to the internal load-bearing frame 2 through the transom interface box 26. The transom interface box 26 is equipped with a rainproof eave, sealing plate, and drip bend on the outside, and an insulating lining and a drip tray 31 on the inside.

[0104] As an example, each cross-frame pipeline includes an outer fixing clamp 27, a flexible connection section 28, and an inner fixing clamp 29. The outer fixing clamp 27 is fixed to the outer load-bearing frame 1, and the inner fixing clamp 29 is fixed to the inner load-bearing frame 2 or the main body of the additive / subtractive material equipment. The flexible connection section 28 is located between the two sets of fixing clamps. This arrangement can change the bending shape when the inner load-bearing frame 2 is fine-tuned or thermally displaced relative to the outer load-bearing frame 1, avoiding the pipeline being straightened and forming additional rigid constraints. The U-shaped arrangement and bending radius requirements are beneficial to extending the hose life. During the release of the transport locking assembly and the fine-tuning of the inner load-bearing frame 2, the U-shaped flexible connection section 28 can change the bending shape and will not be straightened to form rigid tie rod constraints. After the hose is pressurized, a joint reaction force will be generated. This reaction force needs to be evaluated during the design phase. The flexible connection can only weaken the additional constraints and cannot completely eliminate the joint force.

[0105] As an example, cables are equipped with independent slack bends, stress-relief clamps at both ends, and sealing caps at the compartment penetration points; tightening cables and using cable ties to bridge the inner and outer frames are prohibited. Cables, grounding conductors, and ducts are all equipped with displacement margins and flexible sections to reduce the additional constraints on the inner frame from cross-frame connections; the water collection pan 31 monitors for leaks and triggers the cutting off of the medium and cancellation of processing capabilities, improving operational safety. Equipment protective grounding uses flexible grounding conductors with displacement margins and cannot rely on three reference support contact surfaces as the sole grounding path. The flexible compensation section 30 of the duct adapts to the medium and temperature conditions, and the rigid ducts on both sides of the flexible compensation section 30 are equipped with independent supports. The low-temperature pipeline insulation vapor barrier continuously covers the U-shaped flexible connection section 28; the compartment insulation sleeve and enclosure insulation overlap and seal; temperature sensors 19 are arranged on the outer surface of the insulation as needed. The water collection pan 31 monitors internal water leakage; in the event of leakage, the corresponding medium branch is cut off, and processing capabilities are cancelled. The dimensions of the flexible pipeline need to be checked in conjunction with the working clearance to avoid the pipeline still exerting rigid constraints on the built-in load-bearing frame 2 after locking and retraction.

[0106] As a preferred example, the processing chamber temperature is 22±2℃, relative humidity is 40%-50%, external pressure difference is 5-15Pa, dew point safety margin is 3℃, hysteresis when exiting anti-condensation mode is 1℃, and the continuous qualified time for the indicators is 10min. The above parameters are for illustrative purposes only and do not replace actual engineering testing and verification.

[0107] As an example, data from temperature sensor 19, humidity sensor 20, and differential pressure sensor 25 are collected simultaneously to record surface temperature, dew point margin, and two sets of differential pressures. The system recovery capability is observed by simulating the conditions of hatch opening, exhaust ventilation changes, and cooling water commissioning. The environmental protection effect is evaluated using stability indicators, node dew point margin, and system recovery time.

[0108] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
