Description

Technical Field

[0001] The present invention relates to the technical field of hot-dip tinning devices for metal parts, and in particular to a hot-dip tinning device for aviation alloy metal parts and a method thereof. Background Art

[0002] As a key conductive component, aircraft engine connectors need to use hot-dip tinning process to improve their high-temperature oxidation resistance and electrical contact reliability.

[0003] However, traditional tinning baths often use rigid fixtures to secure the workpiece at single or multiple points. During the immersion plating process, these fixtures can create dead zones for the tin solution, leading to thin or missing coatings. This is particularly true for porous and curved aerospace alloy parts. Existing clamping methods cannot avoid this obstruction, requiring repeated adjustments to the immersion angle, severely impacting process efficiency. Summary of the Invention

[0004] The object of the present invention is to provide a hot-dip tinning device and method for aviation alloy metal parts to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a hot-dip tinning device for aviation alloy metal parts, comprising:

[0006] a tinning tank into which molten tin is poured;

[0007] The drum is rotatably installed in the tinning tank and is driven by a driving motor through gear transmission to rotate continuously;

[0008] The composite clamp includes a symmetrically arranged fixed seat, a first pressing block, a movable seat, and a second pressing block. The fixed seat and the movable seat are respectively linked to the base through a first driven component and a second driven component. The base is driven by the linkage component to perform radial reciprocating motion, so that the first pressing block and the second pressing block alternately clamp the metal part, avoiding the formation of dead corners for tin liquid flow at the clamping position;

[0009] The linkage assembly includes a portal frame, cylindrical pins, cylindrical cams and driven bevel gears. The cylindrical cams are driven by the rotating shaft of the main drive device, converting the rotary motion into synchronous radial reciprocating motion of the base, thus realizing dynamic switching of the clamping point.

[0010] A lateral pushing assembly is driven by an adjusting motor to control the synchronous horizontal displacement of multiple moving seats to adjust the positioning of the second pressing block on the metal part;

[0011] Among them, the continuous rotation of the drum and the reciprocating motion of the base work together to enable the metal parts to dynamically adjust the contact position during the immersion plating process to ensure the uniformity of the coating.

[0012] Preferably, the linkage assembly further comprises a driving bevel gear, a rotary motor and a rotary shaft, wherein the driving bevel gear is fixed on the rotary shaft and meshes with the driven bevel gear;

[0013] The cylindrical cam is coaxially connected to the driven bevel gear, and its wheel groove cooperates with the cylindrical pin of the portal frame to convert the continuous rotation of the rotating shaft into the synchronous linear reciprocating motion of the base.

[0014] Preferably, the first driven assembly includes a No. 1 clamping column and a No. 1 push bar, and the No. 1 push bar is fixed to the bottom bracket and connected to the first pressing block;

[0015] The first driving groove consists of an upper oblique groove and a lower linear groove. When the bottom bracket moves downward, the first pressing block extends outward to clamp the metal part; when the bottom bracket moves upward, the first pressing block remains stationary and then retracts.

[0016] Preferably, the second driven assembly includes a second clamping column and a second push bar, and the second push bar is slidably inserted into the matching sleeve and connected to the second pressing block;

[0017] The second driving groove consists of a straight groove and an oblique groove. When the bottom bracket moves downward, the second pressing block remains stationary and then retracts; when the bottom bracket moves upward, the second pressing block extends outward to clamp the metal piece.

[0018] Preferably, the lateral pushing assembly includes a vertical screw and a spur gear, and the regulating motor drives the lateral screw to drive the driven rack, driving the spur gear to rotate and make the vertical screw rise and fall;

[0019] The toggle rod slides along the oblique groove, forcing the moving seat to move horizontally to position the metal part.

[0020] Preferably, there are no less than six mounting platforms distributed in a circular array on the surface of the drum, and a plurality of base supports are provided on each mounting platform;

[0021] The linkage components of adjacent bases are centrally controlled by the same main drive device to ensure synchronous dipping and dynamic clamping of multi-station metal parts.

[0022] Preferably, the fixed seat and the movable seat of the composite clamp are respectively provided with a limit plate and a rectangular long slide groove;

[0023] The limiting block of the limiting plate cooperates with the rectangular long slide groove to constrain the horizontal motion trajectory of the moving seat, prevent deviation and improve assembly accuracy.

[0024] Preferably, L-shaped support brackets are symmetrically arranged on both sides of the tin plating tank, and the support brackets are driven to rise and fall by a hydraulic cylinder to drive the rotating drum to immerse in or remove from the molten tin liquid;

[0025] The drum keeps rotating continuously during the immersion plating process, and combined with the reciprocating motion of the base, it eliminates the dead angle of tin liquid flow and ensures the uniformity of the plating layer.

[0026] Preferably, the rotary motor and linkage assembly of the main drive device are integrated inside the drum, reducing the external transmission structure.

[0027] A method for using a hot-dip tinning device for aviation alloy metal parts, the method comprising the following steps:

[0028] S1: Place the metal part on the mounting table of the rotating drum, adjust the motor to drive the horizontal screw, so that the toggle rod of the horizontal pushing assembly slides along the oblique groove of the moving seat, forcing the moving seat to move horizontally, and adjust the second pressure block to position the metal part;

[0029] S2: Start the hydraulic cylinder to drive the support bracket to descend, so that the rotating drum and metal parts are immersed in the molten tin liquid in the tin plating tank;

[0030] S3: Turn on the driving motor to drive the driving gear to rotate, drive the drum to rotate continuously, and at the same time start the rotating motor to drive the rotating shaft and the driving bevel gear, and drive the cylindrical cam to rotate through the driven bevel gear;

[0031] S4: The wheel groove of the cylindrical cam cooperates with the cylindrical pin of the portal frame to convert the rotational motion into the radial reciprocating motion of the base, driving the first and second driven assemblies to move alternately;

[0032] S5: When the bottom bracket moves downward, the first pressing block extends outward through the oblique groove of the first driving groove to clamp the metal part, and the second pressing block retracts and releases through the oblique groove of the second driving groove; when the bottom bracket moves upward, the second pressing block extends outward through the linear groove to clamp, and the first pressing block retracts and releases through the linear groove, forming an alternating clamping.

[0033] S6: Through the continuous rotation of the drum and the reciprocating motion of the base, the contact position of the metal parts is dynamically adjusted to eliminate the dead angle of tin liquid flow and ensure uniform coating coverage;

[0034] S7: After the immersion plating is completed, the hydraulic cylinder drives the support frame to rise and take out the metal parts.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. This invention achieves alternating clamping of metal parts through the collaborative design of a composite clamp and linkage components. Dynamic switching of clamping points avoids continuous obstruction of molten tin flow by a single fixed position, making it particularly suitable for porous and curved aviation alloy parts. Furthermore, the continuous rotation of the drum keeps the metal part in a dynamic adjustment state during the immersion plating process, further eliminating dead zones in the molten tin flow.

[0037] 2. Through the linkage assembly consisting of a portal frame, cylindrical pins, cylindrical cams and driven bevel gears, the continuous rotational motion of the rotating shaft can be converted into the synchronous radial reciprocating motion of multiple bases, so that the bases are away from or in contact with the metal parts. The advantage of this arrangement is that the reciprocating bases can not only meet the bottom support of the metal parts during assembly, but also avoid the formation of dead angles in the flow of tin liquid at the bottom contact parts of the metal parts.

[0038] 3. In the present invention, the alternating action of the first pressing block and the second pressing block is automatically triggered by mechanical linkage, without the need for manual intervention, thus avoiding the tedious process of repeated adjustments in traditional processes.

[0039] 4. The lateral push assembly of this invention achieves synchronized horizontal motion control of multiple moving seats by rotating a lateral lead screw driven by an adjustable motor. This design simplifies and swifts the positioning and assembly of metal parts on the mounting table, improving production efficiency. Furthermore, the multiple lateral push assemblies, consisting of vertical push bars, toggle rods, nut plates, vertical lead screws, and spur gears, are all driven by a single adjustable motor, achieving centralized power control and distribution, reducing energy consumption and manufacturing costs.

DETAILED DESCRIPTION

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0053] See also Figures 1 to 11 The present invention provides a technical solution: a hot-dip tinning device for aviation alloy metal parts, comprising a tinning tank, in which molten tin liquid is injected, two groups of L-shaped support brackets are symmetrically arranged on the tinning tank, and a hydraulic cylinder is provided on the tinning tank for pushing the support brackets to move up and down; a rotating drum is installed between the two groups of support brackets for limiting rotation, such as Figure 3 As shown, the left end of the drum extends into the left support bracket and is fixedly sleeved with a driven gear, which is internally meshed with the driving gear. The driving gear is driven to rotate by the driving motor, thereby driving the drum to perform continuous rotational motion in the tinning tank.

[0054] like Figure 4-Figure 7As shown, a plurality of mounting platforms distributed in a circular array are protruding from the rotating drum, and the number of mounting platforms is set to be no less than six; a plurality of linearly distributed base supports are provided on each mounting platform, and each base support is driven by a group of linkage components to perform radial reciprocating motion, and the multiple groups of linkage components are driven by a group of main drive devices to provide driving force; the linkage component includes a portal frame, a cylindrical cam and a driven bevel gear, the driven bevel gear is limited to be rotated and installed in the rotating drum and connected to the main drive device, the portal frame is limited to be slidably installed in the mounting platform, one end of the base support contacts the metal part, and the other end of the base support extends into the mounting platform and is fixedly connected to the portal frame, the inner side of the end of the portal frame away from the base support is fixedly connected with a cylindrical pin, the cylindrical pin is inserted in the wheel groove of the cylindrical cam, and the end of the cylindrical cam away from the portal frame is coaxially fixedly connected to the driven bevel gear; the main drive device includes a driving bevel gear, a rotating shaft and a rotating motor, the driven bevel gear is meshed and connected to the driving bevel gear, the driving bevel gear is fixedly sleeved on the rotating shaft, the rotating shaft is limited to be rotated and installed in the rotating drum and fixedly connected to the output shaft of the rotating motor.

[0055] Furthermore, through the linkage assembly composed of the portal frame, cylindrical pin, cylindrical cam and driven bevel gear, the continuous rotational motion of the rotating shaft can be converted into the synchronous radial reciprocating motion of multiple bases, so that the bases are away from or in contact with the metal parts. The advantage of this arrangement is that the reciprocating bases can not only meet the bottom support of the metal parts during assembly, but also avoid the formation of dead corners in the flow of tin liquid at the bottom contact part of the metal parts.

[0056] like Figure 5 、 Figure 7-Figure 8 As shown, the composite clamp includes two groups of fixed seats, a first pressure block, two groups of movable seats and a second pressure block. The two groups of fixed seats are symmetrically arranged at the horizontal ends of the base bracket, and each group of fixed seats is provided with two first pressure blocks for limited sliding installation. The first pressure blocks are driven by the first driven assembly and press or release the metal parts; the two groups of movable seats are symmetrically arranged at the front and rear ends of the base bracket, and each group of movable seats is provided with two second pressure blocks for limited sliding installation. The second pressure blocks are driven by the second driven assembly and press or release the metal parts; the first driven assembly and the second driven assembly are both powered by the base bracket; when the base bracket moves up, the first pressure block releases the metal part and the second pressure block clamps the metal part; when the base bracket moves down, the second pressure block releases the metal part and the first pressure block clamps the metal part; the first pressure block and the second pressure block alternately press the metal part, which can not only stably clamp the metal part, but also avoid the formation of a dead angle for the flow of tin liquid at the contact part of the side wall of the metal part.

[0057] like Figure 7-Figure 8As shown, the first driven assembly includes a No. 1 card column and a No. 1 push strip, one end of the No. 1 push strip is fixedly connected to the bottom bracket, and the other end of the No. 1 push strip extends into the fixed seat and is fixedly connected to the No. 1 card column, and a first driving groove for accommodating the No. 1 card column is opened on the first pressing block; the first driving groove is composed of an upper oblique groove and a lower straight groove, when the No. 1 push strip drives the No. 1 card column downward along with the bottom bracket, the first pressing block first extends outward to press the metal part and then remains stationary; when the No. 1 push strip moves upward along with the bottom bracket, the first pressing block first remains stationary and then retracts inward to release the metal part;

[0058] like Figure 7-Figure 8 As shown, the second driven assembly includes a No. 2 clamping column, a No. 2 push strip and a matching sleeve, the matching sleeve is fixedly connected to the bottom bracket, one end of the No. 2 push strip is limitedly slidably inserted in the matching sleeve, the other end of the No. 2 push strip extends into the moving seat and is fixedly connected to the No. 2 clamping column, a second driving groove is provided through the second pressure block, and a matching sliding groove is provided on the upper surface of the mounting table to accommodate the free sliding of the No. 2 push strip; the second driving groove is composed of a straight groove at the upper end and an oblique groove at the lower end. When the No. 2 push strip drives the No. 2 clamping column downward along with the bottom bracket, the second pressure block first remains stationary and then retracts inward to loosen the metal part. When the No. 2 push strip drives the No. 2 clamping column upward along with the bottom bracket, the second pressure block first extends outward to clamp the metal part, and then remains stationary.

[0059] like Figures 9-11 As shown, the two adjacent groups of moving seats move horizontally toward each other under the drive of the lateral pushing assembly, which can adjust the original position of the second pressure block, making it convenient to place and position the metal parts; two groups of limit plates are symmetrically arranged on the outside of each group of moving seats, the bottom of the limit plate is fixedly connected to the mounting table, and a limit block is protruding from the side of the limit plate close to the moving seat, and a rectangular long slide groove for accommodating the limit block is opened on the side wall of the moving seat, thereby achieving a lateral limit effect on the moving seat;

[0060] The horizontal pushing assembly includes a vertical push bar, a toggle rod, a nut plate, a vertical screw and a spur gear. One end of the vertical push bar is fixedly connected to the nut plate, and the other end of the vertical push bar passes through the limit plate and is fixedly connected to the cover plate, and no less than three toggle rods are fixedly connected to the side wall of the vertical push bar. An oblique groove for accommodating the toggle rod is provided on the outer wall of the movable seat. The nut plate is limited and slidably installed in the mounting platform. An inner screw hole for accommodating the vertical screw is provided through the middle part of the nut plate. One end of the vertical screw is limited and rotatably installed in the mounting platform through a rotating member, and the other end of the vertical screw passes through the inner screw hole and is coaxially fixedly connected to the spur gear. Multiple spur gears in the same mounting platform are fixedly connected to the driven rack, and the end of the driven rack away from the driven gear is fixedly connected to the active plate. A horizontal lead screw is inserted into the active plate. The horizontal lead screw is limited and rotatably installed in the mounting platform and the positive and negative rotation is controlled by the adjusting motor.

[0061] Furthermore, multiple horizontal pushing assemblies consisting of vertical push bars, toggle rods, nut plates, vertical screws and spur gears are driven by a set of adjusting motors, so that multiple moving seats on the same mounting platform can move synchronously, thereby improving the assembly efficiency of metal parts.

[0062] When using this device: first, the metal parts to be processed are placed one by one in multiple composite clamps on the mounting table. After placement, the regulating motor is turned on to drive the horizontal screw to rotate. Under the rotational action of the internal and external threads, the active plate is forced to drive the driven rack to move horizontally. The driven rack acts on multiple spur gears, so that each spur gear drives a vertical screw to rotate. Similarly, under the rotational action of the internal and external threads, the nut plate is forced to drive the vertical push bar downward. At this time, the moving seat is squeezed by the toggle rod due to the oblique groove on its upper side, so that it moves toward the direction of the metal part, and the cover plate just fits against the limit plate and the upper end surface of the moving seat. As the displacement of the moving seat changes, the second pressing block clamps the metal part.

[0063] Then, the hydraulic cylinder is turned on to push the support bracket downward, so that the drum and the metal parts assembled on it are immersed in the tinning tank together. At the same time, the driving motor is turned on to drive the driving gear to rotate. The driving gear acts on the driven gear, so that the drum rotates continuously in the tinning tank. In this process, the rotating motor is turned on to make its rotating shaft drive multiple driving bevel gears to rotate, and the driving bevel gear acts on multiple driven bevel gears, so that the driven bevel gear drives the cylindrical cam to rotate continuously. The wheel groove of the cylindrical cam acts on the cylindrical pin, so that the cylindrical pin drives the cylindrical pin to rotate continuously. The movable door frame and the base perform radial reciprocating motion. When the base moves downward, the first pressure block clamps the metal part under the action of the first driven component and the second driven component, and then the second pressure block releases the metal part; when the base moves upward, the second pressure block clamps the metal part under the action of the first driven component and the second driven component, and then the first pressure block releases the metal part; this is repeated, so that the first pressure block and the second pressure block alternately press the metal part, which can not only stably clamp the metal part, but also avoid the formation of a dead angle of tin liquid flow at the contact part of the side wall of the metal part.

[0064] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
