Description

Technical Field

[0001] This invention relates to the field of torque converter repair, and more particularly to an integrated repair device for torque converter laser welding and dynamic balancing. Background Technology

[0002] As a core power transmission component in automotive automatic transmission systems, the high-speed rotational stability of the rotor assembly of the hydraulic torque converter directly affects the NVH (noise, vibration, and harshness) performance of the entire vehicle. Dynamic balancing of the torque converter is required during production. Currently, the industry-standard method for this is to laser-weld a balance block to the outer edge of the pump impeller side face of the torque converter.

[0003] Existing torque converter balancing repair processes mainly involve the following technical solutions, but all of them have limitations to varying degrees: Traditional mainstream processes employ a separate operation mode for dynamic balancing testing and welding correction. This involves first detecting the imbalance and phase angle on a dedicated dynamic balancing machine, recording the data, disassembling the workpiece, and then manually or robotically transferring it to the welding station for re-clamping and welding. This often requires multiple cycles of testing, welding, and retesting to meet the acceptable standard, which severely reduces production efficiency, and the accumulated errors affect the final balancing accuracy.

[0004] To address the aforementioned efficiency issues, some devices integrating dynamic balancing and welding functions on a single platform have emerged in the market. However, the pump-end housing of torque converters is typically a thin-walled structure (thickness mostly between 1.5mm and 3mm). During the laser welding of the balance block, localized high-temperature heat input can easily cause thermal warping deformation of the housing. This microscopic deformation alters the rotor's center of mass distribution, resulting in a new imbalance after welding the balance block, even though the initial imbalance is eliminated. This secondary imbalance is a key bottleneck affecting the first-pass yield of repairs. Therefore, there is an urgent need to develop an integrated laser welding and dynamic balancing repair device for torque converters that can eliminate repeated clamping errors, has a clamping mechanism that actively avoids the repair area, and provides adaptive internal support and efficient heat dissipation during the welding process. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated repair device for torque converter laser welding and dynamic balancing to solve the above-mentioned problems. The specific technical solution is as follows: A torque converter laser welding and dynamic balancing integrated repair equipment, applied to torque converter pump end repair, includes: platform; A dynamic balancing testing mechanism, set on the platform, is used to detect the imbalance and phase at the pump end of the torque converter; A balance block welding mechanism is provided on the platform for welding balance blocks to the outer edge of the outer end of the torque converter pump end. A clamping mechanism is disposed on the platform and located between the dynamic balancing detection mechanism and the balance block welding mechanism, and is used to clamp and transfer the torque converter pump end; The control unit is connected to the dynamic balancing detection mechanism, the balance block welding mechanism, and the clamping mechanism via signals, respectively. The clamping mechanism includes a clamping component and a telescopic component. The clamping component is used to clamp the positioning area of ​​the torque converter pump end, and the positioning area avoids the repair area on the torque converter pump end determined by the dynamic balance detection mechanism. The telescopic component is disposed on the side of the clamping component, and the telescopic component includes a plurality of telescopic rods arranged side by side and a flexible heat-conducting sheet connected to the end of the telescopic rods; Several of the telescopic rods are configured to extend and retract to adapt to the curvature of the inner side of the outer end edge of the torque converter pump end, such that when the clamping assembly clamps the torque converter pump end, a portion of the telescopic rods are squeezed back by the inner side of the outer end edge, and the flexible heat-conducting sheet deforms and abuts against the inner side of the outer end edge of the torque converter pump end to provide support and conduct heat from the inside during welding by the balance block welding mechanism.

[0006] As an improvement to the above technical solution, the telescopic rod includes a rod body, a sliding sleeve slidably sleeved outside the rod body, and an elastic reset member disposed between the rod body and the sliding sleeve. The flexible heat-conducting sheet is installed at the end of the sliding sleeve, and the elastic reset member is configured to provide an elastic force that causes the sliding sleeve to extend outward.

[0007] As an improvement to the above technical solution, the flexible heat-conducting sheet is made of one or more composite materials selected from copper foil, graphite sheet or indium foil, and the thickness of the flexible heat-conducting sheet is 0.05mm-0.2mm.

[0008] As an improvement to the above technical solution, the clamping assembly includes at least two opposing jaws, and a wear-resistant layer is detachably connected to the clamping surface of the jaws.

[0009] As an improvement to the above technical solution, the clamping mechanism further includes a motion drive module, which is signal-connected to the control unit and is used to drive the clamping assembly to move linearly or rotate between the dynamic balance detection mechanism and the balance block welding mechanism.

[0010] As an improvement to the above technical solution, the dynamic balancing detection mechanism includes a spindle unit, a drive unit, and a vibration sensor. The spindle unit is configured to be connected to the mounting bolt hole of the torque converter pump end through a conformal flange. The vibration sensor is configured to collect the vibration signal when the spindle unit rotates and transmit it to the control unit.

[0011] As an improvement to the above technical solution, the balance block welding mechanism includes a laser generator, a galvanometer scanning head, and a wire feeding assembly. The galvanometer scanning head is configured to focus the laser beam at a specified phase angle position on the outer side of the outer edge of the torque converter pump end according to the coordinate information sent by the control unit.

[0012] As an improvement to the above technical solution, the surface of the flexible heat-conducting sheet is plated with a nickel-phosphorus alloy layer or coated with a high-temperature resistant and oxidation-resistant coating.

[0013] As one of the improvements to the above technical solution, a safety protective cover is also included. The safety protective cover is installed outside the dynamic balancing detection mechanism, the balance block welding mechanism and the clamping mechanism. The safety protective cover is provided with a safety door and an observation window that are interlocked with the control unit.

[0014] The beneficial effects of this invention are as follows: by directly transferring the workpiece between the dynamic balancing detection mechanism and the balance block welding mechanism through the clamping mechanism, the integrated process of detection, transfer and welding is realized, avoiding the positioning reference error caused by secondary clamping in the traditional split process, and significantly improving the first-pass yield of dynamic balancing repair.

[0015] Secondly, the clamping assembly dynamically adjusts the clamping position based on the dynamic balance test results, actively avoiding the repair area. This solves the problem that traditional clamps easily obstruct welding points, eliminating the need to loosen the workpiece and readjust the angle, thus ensuring the accuracy of the welding position.

[0016] Furthermore, the telescopic assembly floats independently through several parallel telescopic rods, enabling it to adapt to changes in the curvature of the inner side of the pump end of different torque converter models, achieving a tight fit with the inner wall of the workpiece. Combined with flexible heat-conducting sheets, it provides effective rigid support on the back of the welding area, preventing denting deformation during the welding of thin-walled shells.

[0017] In addition, the flexible heat-conducting sheet and the telescopic rod form an efficient heat dissipation channel, which can quickly dissipate the heat generated by laser welding, reduce the range of the heat-affected zone and the degree of thermal warping of the shell, effectively avoid new imbalance caused by welding thermal deformation, and ensure the stability of dynamic balance performance after repair.

[0018] Finally, the contour-fitting mechanism of the telescopic component allows the same clamping mechanism to adapt to torque converter pump ends with different diameters and radii of curvature, eliminating the need for frequent replacement of special clamps and improving the equipment's versatility and production flexibility.

Of course, implementing any product or method of this application does not necessarily require achieving all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below. 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.

[0028] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] Please see Figures 1-5In this embodiment of the invention, a torque converter laser welding and dynamic balancing integrated repair equipment is applied to the repair of the pump end of the torque converter. It mainly includes a platform 1, a dynamic balancing detection mechanism 2, a balance block welding mechanism 3, a clamping mechanism 4, and a control unit.

[0030] Platform 1 serves as the basic load-bearing structure of the equipment, preferably a rigid frame structure, on which an mounting surface is provided. The dynamic balancing testing mechanism 2, the balance block welding mechanism 3, and the clamping mechanism 4 are all mounted on platform 1.

[0031] The dynamic balancing detection mechanism 2 is located at the first station of platform 1 and is used to detect the imbalance and phase of the torque converter pump end. Specifically, the dynamic balancing detection mechanism 2 includes a spindle assembly for supporting the torque converter, a drive component for rotating the spindle assembly, and a sensor for collecting vibration signals. When the torque converter pump end is clamped on the spindle assembly and rotates, the sensor collects the vibration signal and transmits it to the control unit. The control unit runs a dynamic balancing calculation program to calculate the magnitude of the unbalanced mass at the torque converter pump end and the phase angle of the unbalance, thereby determining the repair area on the torque converter pump end where a balance block needs to be welded, i.e., the target welding position.

[0032] The balance block welding mechanism 3 is located at the second station of platform 1 and is used to weld balance blocks on the outer edge of the outer end of the torque converter pump. The balance block welding mechanism 3 includes a laser source, a beam transmission and focusing assembly, and a wire feeding or block feeding assembly. This mechanism is signal-connected to the control unit, receives the repair area coordinate information sent by the control unit, and precisely focuses the laser beam at a specified phase angle position on the outer edge of the outer end of the torque converter pump to complete the fusion welding and fixing of the balance block.

[0033] The clamping mechanism 4 is mounted on the platform 1 and located between the dynamic balancing detection mechanism 2 and the balance block welding mechanism 3. It is used to clamp and transfer the torque converter pump end. The clamping mechanism 4 is connected to the control unit via signals to achieve automated operation and coordinated action.

[0034] The clamping assembly 41 is used to clamp the positioning area of ​​the torque converter pump end. In this embodiment, the clamping assembly 41 is preferably a multi-jaw chuck structure or a linkage-type jaw 411 structure. Crucially, the positioning area avoids the repair area on the torque converter pump end determined by the dynamic balancing detection mechanism 2. Specifically, after obtaining the phase angle of the repair area, the control unit controls the clamping assembly 41 to adjust the clamping angle or position, ensuring that the clamping point of the clamping assembly 41 falls within a safe range outside the repair area, thus preventing the clamping assembly 41 from obstructing the laser welding path or interfering with the welding position of the balance block.

[0035] The telescopic assembly 42 is disposed on the side of the clamping assembly 41. The telescopic assembly 42 includes several telescopic rods 421 arranged side by side and a flexible heat-conducting plate 422 connected to the end of the telescopic rods 421. The several telescopic rods 421 are independently and slidably disposed on the base of the clamping mechanism 4, configured to adapt to the curvature of the inner side of the outer edge of the torque converter pump end for telescopic extension and retraction. Preferably, the material of the telescopic rods 421 has a better thermal conductivity.

[0036] In operation, when the clamping assembly 41 clamps the torque converter pump end, the telescopic assembly 42 moves synchronously, extending into the inner cavity of the torque converter pump end. Since the outer edge of the torque converter pump end is typically circular or arc-shaped, its inner surface has a certain curvature. As the clamping action progresses, the telescopic rods 421 located at different radial positions in the telescopic assembly 42 will contact the inner side of the outer edge of the torque converter pump end. The telescopic rod 421 that contacts earlier or experiences greater resistance will be squeezed back by the inner side of the outer edge, while the telescopic rod 421 that contacts later or is in a gap will remain extended or retract only slightly. Through this multi-rod independent floating telescopic mechanism, the end profile of the telescopic assembly 42 can automatically conform to the actual curved surface of the inner side of the torque converter pump end.

[0037] At this time, the flexible heat-conducting sheet 422 connected to the end of the telescopic rod 421 deforms and abuts against the inner side of the outer edge of the torque converter pump end. The flexible heat-conducting sheet 422 is preferably a sheet material with high thermal conductivity and certain flexibility, which can fill the microscopic gap between the end face of the telescopic rod 421 and the inner wall of the torque converter, forming a large area of ​​thermal contact surface.

[0038] When the balance block welding mechanism 3 performs welding, the laser acts on the outer edge of the outer end of the torque converter pump end, i.e., the repair area, while the flexible heat-conducting plate 422 is located on the inner side of the back of this repair area. The flexible heat-conducting plate 422 plays a dual role in this process: first, it provides rigid support to prevent the thin-walled shell from denting or warping under the action of welding stress and the gravity of the molten pool; second, it utilizes its high thermal conductivity to quickly conduct the local high-temperature heat generated by welding along the telescopic rod 421, reducing the heat-affected zone and preventing secondary imbalance caused by thermal deformation.

[0039] The control unit is connected to the dynamic balancing detection mechanism 2, the balance block welding mechanism 3, and the clamping mechanism 4 via signals. The control unit is responsible for coordinating the working sequence of each mechanism: first, controlling the dynamic balancing detection mechanism 2 to complete the detection and calculate the repair area; second, controlling the clamping mechanism 4 to adjust the clamping position to avoid the repair area and drive the telescopic component 42 to fit against the inner wall; then, controlling the clamping mechanism 4 to transfer the workpiece to the welding station; and finally, controlling the balance block welding mechanism 3 to perform the welding operation.

[0040] First, by directly transferring the workpiece between the dynamic balancing detection mechanism 2 and the balance block welding mechanism 3 through the clamping mechanism 4, the integrated process of detection, transfer and welding is realized, avoiding the positioning reference error caused by secondary clamping in the traditional split process, and significantly improving the first-pass yield of dynamic balancing repair.

[0041] Secondly, it actively avoids the repair area to ensure welding accessibility. The clamping assembly 41 dynamically adjusts the clamping position based on the dynamic balance test results, actively avoiding the repair area. This solves the problem that traditional clamps easily obstruct welding points, eliminating the need to loosen the workpiece and readjust the angle, thus ensuring the accuracy of the welding position.

[0042] Furthermore, adaptive internal support suppresses welding deformation. The telescopic assembly 42 floats independently through several parallel telescopic rods 421, enabling it to adapt to the curvature changes of the inner side of the pump end of different torque converter models, achieving a tight fit with the inner wall of the workpiece. Combined with the flexible heat-conducting sheet 422, effective rigid support is provided on the back side of the welding area, preventing denting deformation during the welding of thin-walled shells.

[0043] In addition, it features efficient heat dissipation management to avoid secondary imbalances. The flexible heat-conducting sheet 422 and the telescopic rod 421 form an efficient heat dissipation channel, which can quickly dissipate the heat generated by laser welding, reduce the range of the heat-affected zone and the degree of thermal warping of the shell, effectively avoid new imbalances caused by welding thermal deformation, and ensure the stability of dynamic balance performance after repair.

[0044] Finally, it boasts high flexibility and strong adaptability. The contour-following fitting mechanism of the telescopic component 42 allows the same clamping mechanism 4 to adapt to torque converter pump ends with different diameters and radii of curvature, eliminating the need for frequent replacement of dedicated clamps and improving the equipment's versatility and production flexibility.

[0045] In some embodiments, the telescopic rod 421 includes a rod body 4211, a sliding sleeve 4212 slidably sleeved outside the rod body 4211, and an elastic reset member 4213 disposed between the rod body 4211 and the sliding sleeve 4212. Specifically, the rod body 4211 serves as a supporting frame and is fixedly mounted on the base of the clamping mechanism 4, maintaining a relatively stationary position. The sliding sleeve 4212 is sleeved outside the rod body 4211 and can slide freely along the axial direction of the rod body 4211, forming a telescopic kinematic pair. The elastic reset member 4213 is preferably a compression spring, sleeved outside the rod body 4211 and located inside the sliding sleeve 4212, or disposed in a closed cavity between the rod body 4211 and the sliding sleeve 4212, with its two ends respectively abutting against the limiting step of the rod body 4211 and the inner limiting end face of the sliding sleeve 4212.

[0046] The elastic reset member 4213 is configured to provide an elastic force that extends the sliding sleeve 4212 outward; that is, in its natural state, the sliding sleeve 4212 is in its maximum extended position under the push of the elastic reset member 4213. A flexible heat-conducting plate 422 is mounted at the end of the sliding sleeve 4212, i.e., on the side away from the fixed end of the rod 4211. The flexible heat-conducting plate 422 and the end of the sliding sleeve 4212 can be fixed by high-temperature adhesive bonding or mechanical pressing to ensure the continuity of the heat conduction path.

[0047] Regarding the flexible heat-conducting sheet 422, it is made of one or more composite materials selected from copper foil, graphite sheet, or indium foil. The thickness of the flexible heat-conducting sheet 422 is 0.05mm-0.2mm. Specifically, copper foil has excellent thermal conductivity and certain mechanical strength, enabling rapid heat conduction without easy breakage; graphite sheet has extremely high planar thermal conductivity and excellent flexibility, adapting to complex curved surface changes; indium foil has excellent softness and conformability, filling microscopic gaps. In practical applications, depending on the specific heat dissipation requirements of the torque converter material and welding process, a single material or multiple materials can be selected for composite lamination. For example, copper foil can be used as a skeleton to enhance strength, with graphite sheet composited on the surface to improve thermal conductivity, or indium foil composited to enhance interface adhesion. In this embodiment, the thickness is strictly controlled between 0.05mm and 0.2mm. Specifically, if the thickness is less than 0.05mm, the mechanical strength of the heat-conducting sheet is too low, and it is prone to tearing or perforation under the repeated extension and retraction of the telescopic rod 421 and the high temperature impact of welding, resulting in a shortened service life and insufficient heat capacity, with limited instantaneous heat absorption capacity. If the thickness is greater than 0.2mm, although the mechanical strength increases, the flexibility of the material decreases significantly, making it difficult to deform sufficiently under the clamping force of the elastic reset member 4213 to tightly fit the micro-curved surface inside the pump end of the torque converter, easily forming an air insulation layer, increasing the contact thermal resistance, and weakening the heat dissipation effect. A thickness of 0.05mm to 0.2mm can ensure that the heat-conducting sheet has sufficient flexibility to conform to the shape, and can also provide the necessary structural integrity to withstand the thermal stress during the welding process. Preferably, a nickel-phosphorus alloy layer or a high-temperature resistant and anti-oxidation coating can be plated on the surface of the flexible heat-conducting sheet 422.

[0048] In some embodiments, the clamping assembly 41 includes at least two opposing grippers 411, with a wear-resistant layer 412 detachably connected to the gripping surface of the grippers 411. The clamping mechanism 4 also includes a motion drive module 43, which is signal-connected to the control unit and is used to drive the clamping assembly 41 to move linearly or rotate between the dynamic balance detection mechanism 2 and the balance block welding mechanism 3.

[0049] Regarding the dynamic balancing detection mechanism 2 and the balance block welding mechanism 3, the dynamic balancing detection mechanism 2 includes a spindle unit, a drive unit, and a vibration sensor. The spindle unit is configured to connect to the mounting bolt holes of the torque converter pump end through a conformal flange. The vibration sensor is configured to collect vibration signals when the spindle unit rotates and transmit them to the control unit. The balance block welding mechanism 3 includes a laser generator, a galvanometer scanning head, and a wire feeding assembly. The galvanometer scanning head is configured to focus the laser beam at a specified phase angle position on the outer side of the outer edge of the torque converter pump end according to the coordinate information sent by the control unit. Since both the dynamic balancing detection mechanism 2 and the balance block welding mechanism 3 are well known to those skilled in the art (not shown in the figure),

[0050] In some embodiments, a safety cover 5 is also included, which covers the outside of the dynamic balancing testing mechanism 2, the balance block welding mechanism 3 and the clamping mechanism 4. The safety cover 5 is provided with a safety door and an observation window that are interlocked with the control unit.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
