Description

Technical Field

[0001] This invention relates to the field of cladding head technology, and in particular to a multi-channel coaxial powder feeding laser cladding head device. Background Technology

[0002] Multi-channel coaxial powder-feeding laser cladding heads are typically used in laser cladding, laser additive manufacturing, or repair processes. They deliver powder to the laser-affected area via multiple powder feeding channels, where it converges with the laser beam at a predetermined location to form a cladding layer. The cladding head generally integrates powder feeding channels, protective gas channels, cooling channels, and a light-emitting structure. Therefore, the installation position of the cladding head cylinder directly affects powder distribution, laser apposition, and processing stability.

[0003] In the prior art, Chinese Patent No. CN117123800A discloses a high-quality laser cladding equipment and method. It discloses a laser cladding equipment including a cladding head and a powder feeding mechanism. By setting up a powder feeding cylinder, an outer cylinder, an inner cylinder and multiple powder outlet channels, it realizes the conveying and uniform supply of metal powder, so as to improve the powder utilization rate and cladding quality in the laser cladding process.

[0004] Existing multi-channel coaxial powder-feeding laser cladding head devices typically employ mounting sleeves, brackets, threaded clamping components, pressure blocks, or locking components to support and secure the cladding head cylinder during installation. During installation, the operator generally inserts the cladding head cylinder into the mounting sleeve and locks it in place by tightening the clamping components or pushing the sleeve. Some devices also include a tapered guide structure at the end of the cylinder to guide it into the mounting sleeve, assisting in positioning and reducing insertion difficulty. While these structures effectively secure the cladding head cylinder, confirmation of proper installation often relies on manual observation or a feeling of the overall condition after clamping.

[0005] However, if the cladding head cylinder is not perfectly centered or has localized circumferential misalignment, subsequent clamping actions may fix this misalignment, causing the powder feeding channel and laser emission position to shift, affecting the cladding layer forming quality. Localized misalignment can also lead to uneven powder distribution and unstable cladding area, requiring readjustment of the clamping structure after the deviation is detected, reducing assembly efficiency. Existing devices typically lack a multi-point alignment confirmation mechanism before clamping, making it difficult to promptly identify localized cylinder misalignment, thus posing a risk of inaccurate installation.

[0006] Therefore, we propose a multi-channel coaxial powder feeding laser cladding head device. Summary of the Invention

[0007] The purpose of this invention is to provide a multi-channel coaxial powder feeding laser cladding head device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a multi-channel coaxial powder feeding laser cladding head device, comprising a cladding head cylinder, and further comprising:

[0009] The mounting sleeve is fitted onto the outside of the cladding head cylinder;

[0010] The inspection verification component is disposed on the bottom side of the mounting sleeve and arranged at intervals along the circumference;

[0011] Side pressure members are disposed on the middle side of the mounting sleeve and are arranged at intervals along the circumference;

[0012] An extrusion component, wherein the extrusion component is sleeved on the outside of the mounting sleeve;

[0013] A clearance linkage component is provided between the extrusion component and the side pressure component;

[0014] A spinning member, which is rotatably connected to the top of an extrusion member;

[0015] When the cladding head cylinder enters the mounting sleeve, the inspection and verification parts extend radially outward. When any inspection and verification part is not fully extended, the clearance linkage keeps the spinning part in motion. After all inspection and verification parts are fully extended, the clearance linkage releases the restriction, and the spinning part moves axially along the mounting sleeve, causing the side pressure part to press the cladding head cylinder.

[0016] Preferably, the verification component includes:

[0017] A top-shifting rod, which passes through the mounting sleeve;

[0018] The abutting end is located at one end of the top moving rod facing the cladding head cylinder;

[0019] A return elastic element is provided between the top moving rod and the mounting sleeve;

[0020] When the abutting end is pushed against the outer periphery of the molten cladding cylinder, the top moving rod moves outward relative to the mounting sleeve; when the pushing is released, the return elastic element drives the top moving rod back.

[0021] Preferably, the side pressure member includes:

[0022] A movable rod, which passes through the middle of the mounting sleeve;

[0023] A locking block, which is connected to one end of the movable rod;

[0024] A return spring, which is sleeved on the outer surface of the movable rod;

[0025] A pressure block is located at the end of the movable rod away from the mounting sleeve;

[0026] The movable rod responds to the outward position of the top moving rod, and the pressure block can be squeezed relative to the mounting sleeve when the movable rod moves axially, so as to push the locking block toward the cladding head cylinder.

[0027] Preferably, the extrusion member comprises:

[0028] A movable sleeve, which is fitted onto the outside of the mounting sleeve;

[0029] The extrusion block is fixedly connected to the inner wall of the movable sleeve, and the side of the extrusion block near the pressure block is inclined to match the outer contour of the pressure block.

[0030] Preferably, the clearance linkage includes:

[0031] A clearance block, which is fixedly connected to one end of the top shift rod that passes through the mounting sleeve;

[0032] A relief groove is formed at the bottom of the extrusion.

[0033] Preferably, the spun part includes:

[0034] An outer sleeve, which is fixedly connected to the top of the mounting sleeve;

[0035] The push sleeve is threaded to the outer surface of the outer sleeve, and a transfer transmission component is provided between the push sleeve and the extrusion component.

[0036] Preferably, the adapter transmission component includes:

[0037] A retaining ring is fixedly connected to both the outer surface of one end of the extruder and the outer surface of one end of the push sleeve.

[0038] A connecting sleeve, which is fitted between two fixed rings.

[0039] Preferably, an outer conical ring is fixedly connected to the outer surface of the top of the cladding head cylinder, and a fixed bracket is fixedly connected to the top of the mounting sleeve.

[0040] Preferably, the mounting sleeve includes:

[0041] A reference sleeve, which is fixedly connected to the end of a fixed bracket;

[0042] The first sleeve is fixedly connected to the bottom of the reference sleeve, and the side pressure member is located in the middle of the first sleeve;

[0043] The second sleeve is fixedly connected to the bottom of the first sleeve, and the detection and verification component is located in the middle of the second sleeve.

[0044] Preferably, the outer contour dimensions of the outer conical ring are adapted to the inner contour dimensions of the reference sleeve, and the inner contours of the first sleeve and the second sleeve are both stepped.

[0045] The technical effects and advantages of this invention are as follows:

[0046] 1. This invention provides multiple detection and verification components along the circumferential direction on the bottom side of the mounting sleeve. When the cladding head cylinder enters the mounting sleeve, the detection and verification components at different circumferential positions can be pushed outwards, thereby forming a multi-point circumferential verification before side pressure fixing. Compared with the method of judging the installation status by manual observation or single-point contact, this invention can reflect whether there is a local deviation or insufficient entry of the cladding head cylinder based on the extension status of multiple detection and verification components, providing a clear circumferential position basis for subsequent adjustments.

[0047] 2. This invention establishes a mechanical constraint relationship between the extended state of the detection and verification component and the movement of the spinning component through a clearance linkage. When either detection and verification component is not fully extended, the clearance linkage restricts the movement of the spinning component, preventing the extrusion component from prematurely pushing the side pressure component to side-press and fix the cladding head cylinder. This avoids the cladding head cylinder being directly pressed and fixed when it is tilted or partially in place, reducing the need for subsequent loosening, adjustment, and re-tightening, and improving the continuity and reliability of the installation process.

[0048] 3. In this invention, after all the verification parts have fully extended, the clearance linkage releases the restriction on the spinning part, allowing the spinning part to drive the extrusion part to move axially along the mounting sleeve. The axial movement is then converted into a pressing action on the side of the cladding head cylinder through the cooperation of the extrusion part and the side pressing part. This structure creates a continuous mechanical process of "insertion guidance, circumferential verification, restriction release, and lateral pressing," which helps maintain the relative positional relationship between the cladding head cylinder and the mounting sleeve, reducing the risk of powder feeding channel and laser action position displacement due to installation misalignment.

[0049] 4. The technical challenge of this invention lies in how to reliably identify whether the circumferential deviation of the cladding head cylinder is present during insertion, and how to establish a forced mechanical linkage between the detection status and subsequent spinning and side-pressing actions to prevent premature locking before it is fully in place. Its beneficial effect is that through multi-point detection verification and a clearance linkage structure, a mechanical interlock control of "side-pressing only after detection is in place" is achieved. Deviation judgment and sequence control can be completed without additional sensors, thereby improving installation accuracy and stability. This invention solves this problem, achieving unexpected technical results. Attached Figure Description

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] This invention provides, for example Figures 1-7 The image shows a multi-channel coaxial powder feeding laser cladding head device.

[0062] Example 1: Includes a cladding head cylinder 1 and an mounting sleeve 2. The mounting sleeve 2 is fitted on the outside of the cladding head cylinder 1. The inspection and verification component 3 is set on the bottom side of the mounting sleeve 2 and is arranged at intervals along the circumference. The side pressure component 4 is set on the middle side of the mounting sleeve 2 and is arranged at intervals along the circumference. The extrusion component 5 is fitted on the outside of the mounting sleeve 2. The clearance linkage component 6 is set between the extrusion component 5 and the side pressure component 4. The spinning component 7 is rotatably connected to the top of the extrusion component 5.

[0063] When the cladding head cylinder 1 enters the mounting sleeve 2, the inspection verification component 3 extends radially outward. When any inspection verification component 3 is not fully extended, the clearance linkage component 6 keeps the spinning component 7 in motion. After all inspection verification components 3 are fully extended, the clearance linkage component 6 is released from its restriction, and the spinning component 7 moves axially along the mounting sleeve 2, causing the side pressure component 4 to press the cladding head cylinder 1.

[0064] First, align the cladding head cylinder 1 with the mounting sleeve 2 and insert the cladding head cylinder 1 into the mounting sleeve 2. During the insertion process, the outer circumference of the cladding head cylinder 1 gradually contacts the multiple detection verification elements 3 located on the bottom side of the mounting sleeve 2. Since the multiple detection verification elements 3 are arranged at intervals along the circumference of the mounting sleeve 2, the insertion state of the cladding head cylinder 1 at different circumferential positions can act on the detection verification elements 3 at the corresponding positions. When the cladding head cylinder 1 is inserted into the mounting sleeve 2 and the circumferential position is relatively balanced, the outer circumference of the cladding head cylinder 1 can simultaneously push the multiple detection verification elements 3 to extend radially outward; when the cladding head cylinder 1 has a local deviation, at least one detection verification element 3 cannot extend completely outward, or the extension state of the multiple detection verification elements 3 is inconsistent.

[0065] When any of the verification components 3 is not fully extended, the positioning linkage 6 remains in the position that restricts the movement of the spinning component 7. At this time, even if the operator attempts to rotate the spinning component 7, the spinning component 7 cannot effectively drive the extrusion component 5 to move axially along the mounting sleeve 2, and the side pressure component 4 will not prematurely press and fix the cladding head cylinder 1. In this way, the cladding head cylinder 1 will not be directly pressed and fixed by the side pressure component 4 when it is not fully in place or when there is circumferential deviation, so that the deviation installation state can be retained as an adjustable state before pressing, instead of being locked in the initial deviation state.

[0066] Once all the inspection verification pieces 3 have been pushed to their fully extended positions by the cladding head cylinder 1, the clearance linkage 6 releases the restriction on the spinning piece 7. At this point, the operator rotates the spinning piece 7, which moves axially along the mounting sleeve 2, causing the extrusion piece 5 to move relative to the mounting sleeve 2. During its movement, the extrusion piece 5 acts on the side pressure piece 4, causing it to move radially closer to the cladding head cylinder 1 and press and fix it from the side of the cladding head cylinder 1. Thus, the pressing action of the cladding head cylinder 1 occurs after all the inspection verification pieces 3 have completed their extension, creating a mechanical linkage between the installation verification action and the spinning fixing action.

[0067] The verification component 3 is not only used for single-point contact confirmation, but also participates in the installation verification through multiple circumferential positions. Only when all multiple verification components 3 are fully extended will the clearance linkage 6 release the restriction on the spinning component 7; if any verification component 3 is not fully extended, the spinning action of the spinning component 7 will still be restricted. This structure ensures that the clamping action of the cladding head cylinder 1 is constrained by the combined circumferential multi-point positioning, reducing the possibility of clamping based solely on manual observation or single-point contact.

[0068] Through the above structure and operation process, after the cladding head cylinder 1 is inserted into the mounting sleeve 2, its circumferential positioning is first checked by multiple detection and verification components 3. Then, the clearance linkage component 6 determines whether the spinning component 7 can move. Finally, the spinning component 7 drives the extrusion component 5 to push the side pressure component 4 to complete the lateral fixation. This process makes "insertion, verification, release of restriction, and lateral pressure fixation" a continuous mechanical flow. When the cladding head cylinder 1 is not centered or partially not in place, the side pressure component 4 cannot apply pressure in advance, which can reduce the possibility of being directly fixed in an skewed state. After the cladding head cylinder 1 is in place, the spinning component 7 is allowed to drive the side pressure component 4 to press the cladding head cylinder 1 laterally, which helps to maintain the installation position relationship between the cladding head cylinder 1 and the mounting sleeve 2.

[0069] Furthermore, since the verification components 3 are arranged at circumferential intervals, when there is a local deviation in the cladding head cylinder 1, the verification components 3 at different positions will exhibit different outward extension states. The operator can determine the direction of deviation of the cladding head cylinder 1 relative to the mounting sleeve 2 based on the position of the incompletely extended verification component 3, and adjust the cladding head cylinder 1 before the spinning component 7 releases its restriction. In this way, the device not only structurally restricts the spinning and fixing action when not in place, but also provides a clear circumferential positional basis for subsequent position adjustments, making the installation verification and fixing process of the cladding head cylinder 1 more coherent.

[0070] Furthermore, the inspection and verification component 3 includes a top-moving rod 301, which passes through the mounting sleeve 2. The abutting end 302 is located at the end of the top-moving rod 301 facing the cladding head cylinder 1, and the return elastic element 303 is located between the top-moving rod 301 and the mounting sleeve 2.

[0071] When the contact end 302 is pushed against the outer periphery of the cladding head cylinder 1, the top moving rod 301 moves outward relative to the mounting sleeve 2; when the pushing is released, the return elastic element 303 drives the top moving rod 301 back.

[0072] When the cladding head cylinder 1 enters the mounting sleeve 2, its outer periphery contacts multiple abutment ends 302, pushing the corresponding top-moving rods 301 to move outward relative to the mounting sleeve 2. If the cladding head cylinder 1 is in a centered state, the outward movement of the multiple top-moving rods 301 tends to be consistent; if the cladding head cylinder 1 is tilted, the top-moving rods 301 closer to the tilted side will move outward more, while the top-moving rods 301 farther from the tilted side will move outward less. Thus, the tilt direction of the cladding head cylinder 1 can be reflected by the difference in the outward movement of the multiple detection verification parts 3.

[0073] When the cladding head cylinder 1 exits the mounting sleeve 2 or ceases to push against the contact end 302, the return elastic element 303 drives the top displacement rod 301 to return, restoring the detection verification element 3 to its initial position. Thus, the detection verification element 3 can form a circumferential multi-point verification before the cladding head cylinder 1 is laterally pressed and fixed, allowing the operator to determine the skew position based on the outward displacement at different locations, and providing a mechanical basis for the subsequent clearance linkage element 6 to restrict or release the action of the spinning element 7.

[0074] Furthermore, the side pressure member 4 includes a movable rod 401, which passes through the middle of the mounting sleeve 2. A locking block 402 is connected to one end of the movable rod 401. A return spring 403 is sleeved on the outer surface of the movable rod 401. A pressure block 404 is located at the end of the movable rod 401 away from the mounting sleeve 2.

[0075] When all the inspection and verification parts 3 are fully extended and the clearance linkage part 6 is released from the restriction on the spinning part 7, the spinning part 7 can drive the extrusion part 5 to move axially along the mounting sleeve 2; when the extrusion part 5 acts on the pressure block 404, the pressure block 404 drives the movable rod 401 to move radially along the mounting sleeve 2, so that the locking block 402 moves towards the side of the cladding head cylinder 1.

[0076] During the operation of the side-pressing component 4, the pressure block 404, acting as the force-bearing part between the extrusion component 5 and the movable rod 401, receives the pushing force of the extrusion component 5 and transmits this pushing force to the movable rod 401 and the locking block 402, causing the locking block 402 to laterally press against the cladding head cylinder 1. The return spring 403 is used to drive the movable rod 401 back to its original position after the extrusion component 5 releases its pushing force on the pressure block 404, causing the locking block 402 to exit the side-pressing position on the cladding head cylinder 1.

[0077] Therefore, the lateral pressing action of the side pressing component 4 is not directly driven by the detection and verification component 3, but is jointly triggered by the spinning component 7 and the extrusion component 5 after the detection and verification component 3 completes the circumferential verification and the clearance linkage component 6 is released from the restriction. This action sequence can prevent the cladding head cylinder 1 from being prematurely fixed by the side pressing component 4 when it is tilted or has not fully entered the mounting sleeve 2 in some areas.

[0078] Furthermore, the extrusion member 5 includes a movable sleeve 501, which is sleeved on the outside of the mounting sleeve 2. The extrusion block 502 is fixedly connected to the inner wall of the movable sleeve 501, and the side of the extrusion block 502 near the pressure block 404 is inclined to match the outer contour of the pressure block 404.

[0079] When all the inspection and verification parts 3 are fully extended and the clearance linkage 6 releases the restriction on the spinning part 7, the spinning part 7 rotates and generates axial feed, driving the extrusion part 5 to move axially along the mounting sleeve 2. The moving sleeve 501 moves synchronously with the extrusion part 5, and the extrusion block 502 moves with the moving sleeve 501 closer to the pressure block 404 of the side pressure part 4.

[0080] During the movement of the extruder 5, the inclined side of the extrusion block 502 abuts against the pressure block 404, causing the pressure block 404 to be subjected to a component force toward the side of the cladding head cylinder 1, which in turn drives the movable rod 401 and the locking block 402 to move radially toward the cladding head cylinder 1. Through this inclined surface engagement, the axial feed action of the spinning member 7 is converted into the radial side pressing action of the side pressing member 4.

[0081] The above structure causes the axial movement of the extrusion member 5 to be constrained by the release state of the clearance linkage member 6. Only after multiple inspection and verification members 3 have completed the extension verification can the extrusion member 5 push the side pressure member 4 to perform the side pressure action, thereby reducing the possibility that the cladding head cylinder 1 will be prematurely side-pressed and fixed in an inclined state.

[0082] Furthermore, the clearance linkage 6 includes a clearance block 601, which is fixedly connected to one end of the top shift rod 301 that passes through the mounting sleeve 2, and a clearance groove 602 is opened at the bottom of the extrusion member 5.

[0083] During the process of the cladding head cylinder 1 entering the mounting sleeve 2, the outer periphery of the cladding head cylinder 1 pushes against the contact end 302, causing the top shift rod 301 to drive the relief block 601 to move. When the inspection and verification part 3 is not fully pushed, the relief block 601 is still in the relief groove 602. At this time, the movement of the extrusion part 5 and the spinning part 7 is restricted, and the spinning part 7 cannot drive the extrusion part 5 to enter the side pressing action.

[0084] After the cladding head cylinder 1 fully pushes against the multiple inspection and verification parts 3, each top shifting rod 301 drives the corresponding relief block 601 to exit from the relief groove 602, thereby releasing the relief linkage 6 from restricting the spinning part 7 and the extrusion part 5. At this time, the spinning part 7 can continue to operate and drive the extrusion part 5 to act on the side pressure part 4, which then side-pressures and fixes the cladding head cylinder 1.

[0085] Through the above structure, the displacement linkage 6 links the displacement state of the detection verification component 3 with the action state of the spinning component 7. When any detection verification component 3 is not fully extended, the corresponding displacement block 601 has not yet exited the displacement groove 602, and the spinning component 7 is restricted; after multiple detection verification components 3 have fully extended, the displacement block 601 exits the displacement groove 602, and the action restriction of the spinning component 7 is released. Thus, the side-pressing fixing action can be performed after the cladding head cylinder 1 has completed circumferential verification, reducing the possibility of the skewed state being prematurely pressed and fixed, and allowing the operator to determine the skewed side or insufficiently entered position of the cladding head cylinder 1 based on the position of the displacement block 601 that has not exited the displacement groove 602.

[0086] Furthermore, the spinning component 7 includes an outer sleeve 701, which is fixedly connected to the top of the mounting sleeve 2. The push sleeve 702 is threadedly connected to the outer surface of the outer sleeve 701, and a transfer transmission component 8 is provided between the push sleeve 702 and the extruder 5.

[0087] After the cladding head cylinder 1 enters the mounting sleeve 2 and all the inspection and verification components 3 have extended outwards, the clearance linkage 6 releases the restriction on the spinning component 7. At this time, the operator can rotate the push sleeve 702, which rotates relative to the outer sleeve 701 and generates a feeding action through the threaded engagement. Since a transfer transmission component 8 is provided between the push sleeve 702 and the extrusion component 5, the feeding action of the push sleeve 702 can be transmitted to the extrusion component 5, allowing the extrusion component 5 to continue acting on the side pressure component 4.

[0088] When the repositioning linkage 6 is not released from its restriction, the rotation of the push sleeve 702 is restricted, and the extrusion member 5 cannot push the side pressure member 4 to side-press and fix the cladding head cylinder 1 in advance. After the repositioning linkage 6 is released from its restriction, the push sleeve 702 can drive the extrusion member 5 to move through the transfer transmission member 8. Thus, the movement of the spinning member 7 is incorporated into the pre-restriction relationship formed by the detection verification member 3 and the repositioning linkage 6, so that the spinning fixing action will not deviate from the circumferential verification state of the cladding head cylinder 1.

[0089] Through the above structure, the spinning member 7 transforms the operator's spinning operation into the feeding action of the extrusion member 5, and this action can only be effectively executed after the clearance linkage member 6 releases its restriction. This reduces the possibility that the cladding head cylinder 1 may be prematurely clamped and fixed when it is tilted or partially not fully inserted into the mounting sleeve 2.

[0090] Furthermore, the transfer transmission component 8 includes a fixing ring 801. The outer surface of one end of the extrusion component 5 and the outer surface of one end of the push sleeve 702 are both fixedly connected to the fixing ring 801, and the connecting sleeve 802 is sleeved between the two fixing rings 801.

[0091] After the release of the restriction on the spinning member 7 by the repositioning linkage 6, the push sleeve 702 can rotate relative to the outer sleeve 701 and generate a feeding action. When the push sleeve 702 moves, the feeding action of the push sleeve 702 is transmitted to the squeezing member 5 through the fixing ring 801 on one end of its outer surface, the fixing ring 801 on one end of the squeezing member 5, and the connecting sleeve 802 sleeved between the two fixing rings 801, so that the squeezing member 5 continues to act on the side pressure member 4.

[0092] By setting the connecting sleeve 802 between the two fixed rings 801, the push sleeve 702 and the extrusion member 5 can maintain a connection relationship, and the movement of the push sleeve 702 is transmitted to the extrusion member 5, thereby forming a continuous mechanical transmission between the spinning member 7, the extrusion member 5 and the side pressing member 4.

[0093] Furthermore, an outer conical ring 9 is fixedly connected to the outer surface of the top of the cladding head cylinder 1, and a fixed bracket 10 is fixedly connected to the top of the mounting sleeve 2.

[0094] Furthermore, the mounting sleeve 2 includes a reference sleeve 201, which is fixedly connected to the end of the fixed bracket 10. The first sleeve 202 is fixedly connected to the bottom of the reference sleeve 201, and the side pressure member 4 is located in the middle of the first sleeve 202. The second sleeve 203 is fixedly connected to the bottom of the first sleeve 202, and the detection verification member 3 is located in the middle of the second sleeve 203. The outer contour dimension of the outer cone ring 9 is adapted to the inner contour dimension of the reference sleeve 201. The inner contour of the first sleeve 202 and the inner contour of the second sleeve 203 are both stepped.

[0095] During the process of the cladding head cylinder 1 entering the mounting sleeve 2, the outer conical ring 9 first engages with the reference sleeve 201. The external contour dimensions of the outer conical ring 9 are adapted to the internal contour dimensions of the reference sleeve 201, so that when the cladding head cylinder 1 enters the mounting sleeve 2, it can first form an introductory engagement with the reference sleeve 201 through the outer conical ring 9, reducing the possibility of significant wobble when the cladding head cylinder 1 initially enters the mounting sleeve 2. After the outer conical ring 9 completes the introductory engagement, the cladding head cylinder 1 continues to enter the area where the first sleeve 202 and the second sleeve 203 are located, and sequentially aligns with the side pressure component 4 and the inspection and verification component 3.

[0096] The internal contours of the first sleeve 202 and the second sleeve 203 are both stepped, so that the first sleeve 202 can provide corresponding space for the arrangement and movement of the side pressure member 4, and the second sleeve 203 can provide corresponding space for the arrangement and extension movement of the inspection and verification member 3. Thus, the reference sleeve 201, the first sleeve 202 and the second sleeve 203 correspond to the introduction position, the side pressure position and the inspection and verification position of the cladding head cylinder 1, respectively. After the cladding head cylinder 1 enters the mounting sleeve 2, it first forms an introduction with the reference sleeve 201 through the outer cone ring 9, then the inspection and verification member 3 verifies the circumferential tilt state of the cladding head cylinder 1, and finally the side pressure member 4 fixes the cladding head cylinder 1 by side pressure after the clearance linkage member 6 releases the restriction.

[0097] With the above structure, the outer conical ring 9 and the reference sleeve 201 are mainly used for the initial insertion and engagement of the cladding head cylinder 1 into the mounting sleeve 2. The first sleeve 202 and the second sleeve 203 respectively support the arrangement positions of the side pressure component 4 and the detection and verification component 3, so that the insertion, verification, and side pressure fixing are completed continuously within the same mounting sleeve 2. This structure enables the cladding head cylinder 1 to obtain a relatively stable entry posture before side pressure fixing, and positions the detection and verification component 3 and the side pressure component 4 in positions suitable for their operation, thereby forming a more complete installation verification and side pressure fixing process in conjunction with the aforementioned clearance linkage component 6.

[0098] The overall outer contour of the pressure block 404 is set as a wedge shape, which makes it easy to match the inclined surface of the extrusion block 502, so as to facilitate being extruded and moved. At the same time, the cross-sectional contour of the abutment end 302 is set as a triangle, which makes it easy to be extruded and moved by the outer cone ring 9, and avoids motion interference with the outer cone ring 9.

[0099] A non-slip pad is fixedly connected to the side of the locking block 402 near the cladding head cylinder 1 to prevent the cladding head cylinder 1 from moving easily after being fixed. An interface 11 is provided on the outside of the cladding head cylinder 1 to facilitate connection with the powder supply pipe. Multiple interfaces 11 are provided to connect with multiple powder supply pipes to achieve multi-channel powder supply. At the same time, the bottom of the cladding head cylinder 1 is the laser ejection port, which facilitates the coaxial output of laser and powder.

[0100] Example 2: Building upon Example 1, Example 2 further discloses that the outer side of the cladding head cylinder 1 is provided with multiple interfaces 11 for connecting to corresponding powder supply pipes, thereby achieving multi-channel powder supply. Each interface 11 is connected to a powder supply pipe, enabling the powder to be uniformly delivered to the corresponding channel inside the cladding head cylinder 1, achieving multi-channel coaxial powder feeding. Simultaneously, a laser ejection port is provided at the bottom of the cladding head cylinder 1, allowing the laser beam to be output along the same axis as the powder, thus achieving synchronous action between the powder and the laser during the laser cladding process.

[0101] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
