[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When the present invention is used, the rotational motion of the motor is converted into the linear reciprocating motion of the clamping arm assembly through the rigid connection between the servo motor A and the driving gear. The vertical meshing structure of the driving gear and the bevel gear B utilizes the high transmission efficiency and precise transmission ratio characteristics of the gear transmission to ensure the synchronization and repeatability of the opening and closing of the clamping arm. The reinforced support member adopts I-section steel. Through the upper and lower limit designs in the longitudinal groove, the clamping force is evenly transmitted to the overall frame of the clamping arm mechanism, avoiding the distortion and deformation caused by the traditional cantilever structure when subjected to force, so that the fitting error between the clamping part and the outer edge of the hub is controlled within 0.1mm. The servo motor B drives the meshing transmission of the stepping gear and the guide gear assembly, utilizing the linear motion of the gear rack. Characteristics, converting the angular displacement of the motor into the axial displacement of the support mechanism, the dovetail-shaped matching structure of the guide assembly and the guide groove eliminates the clearance problem existing in the traditional sliding pair through the four-way limit of up, down, left and right, so that the backlash error of the wheel angle adjustment is less than 0.05°. Through the precise design of the mechanical transmission chain, this mechanism realizes precise control of the whole process from clamping force output to angle fine-tuning, and solves the problems of skewed wheel placement and uneven airflow in the heat treatment furnace caused by uneven force and angle deviation during manual operation, ensuring that the aluminum alloy wheels are heat treated in the furnace in the optimal posture, avoiding local overburning or underheating caused by position deviation, and improving the stability of the heat treatment process from the mechanical structure level.

[0020] 2. When the present invention is used, the adjusting push rod adopts an electric push rod structure, and the motor drives the screw nut pair to realize linear motion. Its stroke can be accurately controlled by the encoder. The slider assembly of the moving mechanism adopts the rolling cooperation of ball bearings and T-shaped guide grooves to convert traditional sliding friction into rolling friction, which reduces the movement resistance by more than 60%. At the same time, the slider structure is symmetrically arranged on both sides to balance the lateral force during the movement and avoid the mechanism from being stuck due to unilateral force. The main lifting rope and the auxiliary lifting rope of the ring mechanism form a triangular lifting structure, which uses the flexible characteristics of the wire rope to absorb the impact load during the driving process. At the same time, the quick shackle structure of the lifting ring assembly is used to achieve seamless switching between the lifting state and the track load state. The I-shaped steel beam design of the component, through the double-layer track layout of the top guide groove and the bottom slide groove, enables the moving mechanism and the clamping arm mechanism to move independently or collaboratively, adapting to different furnace mouth positions while meeting the production needs of parallel loading of multiple stations. The U-shaped guide plate of the guide component and the sliding cooperation of the guide component forcibly constrain the moving trajectory through mechanical limits, eliminating the offset of the traditional free moving mechanism caused by inertia or external force interference, and ensuring that the straightness error of the wheel transfer path is less than 0.3mm. The system solves the problems of poor adaptability of traditional single-track equipment to the furnace layout and susceptibility of the lifting process to external interference through the combination of dual-track independent drive and flexible lifting, and realizes rapid deployment and precise positioning of the device in different production scenarios.

[0021] 3. When the present invention is used, the arc-shaped clamping part of the clamping arm assembly and the clamping arm mechanism adopts a detachable design. By replacing modules with different curvatures, it can adapt to the outer edge contour of the aluminum alloy wheel hub with a diameter of 12-24 inches. The side panel assembly can adjust the spacing within the range of 50-150mm through the combined structure of the transverse slide rail and the positioning pin to meet the side limit requirements of wheels of different widths. The split splicing structure of the hub part is connected by bolts with the upper half ring and the lower half ring, and the positioning rings with different inner diameters can be quickly disassembled and replaced to ensure precise matching with the inner ring of the wheel. The cylindrical body of the support mechanism forms a clearance match with the through groove of the drive guide, allowing the hub part to maintain contact with the inner ring of the wheel during axial movement, while at the same time through the guide The lateral limitation of the component prevents the wheel from circumferential rotation during the transfer process. The anti-slip tooth pattern design of the clamping part improves the clamping reliability of heavy wheels by increasing the friction coefficient of the contact surface. The flange structure of the hub component limits the axial movement of the wheel through a mechanical stop, forming a three-dimensional constraint system of radial clamping, axial limitation, and circumferential fixation. This design, through the combination of parametric design of modular components and mechanical limitation structure, can achieve rapid changeover of wheels of different specifications without modifying the main structure of the equipment, solving the problem that traditional special equipment is difficult to adapt to product iteration, significantly improving the production line's responsiveness to multi-variety and small-batch orders, and realizing the needs of flexible production from the mechanical structure level.

DETAILED DESCRIPTION

[0031] 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 implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] For example 1, please refer to Figures 1-8 As shown, the present invention provides a technical solution: an automatic loading device for an aluminum alloy wheel heat treatment furnace, comprising a support mechanism 1, a guide rail assembly 101 is fixedly connected to the bottom end surface of the support mechanism 1, and the guide rail assembly 101 is arranged horizontally;

[0033] The guide rail assembly 101 is internally installed with a clamping arm mechanism 4, and a longitudinal groove is provided inside the clamping arm mechanism 4. The bottom end of the longitudinal groove is fixedly connected to a reinforcing support member 401. The reinforcing support member 401 is longitudinally arranged, and there are two reinforcing support members 401. The two reinforcing support members 401 are arranged in a linear array, and a side plate assembly 4011 is fixedly connected to the front end surface of the clamping arm mechanism 4. The side plate assembly 4011 and the front end surface of the clamping arm mechanism 4 are perpendicularly arranged, and a servo motor A4012 is installed at the top of the side plate assembly 4011. The bottom end of the servo motor A4012 is provided with an output shaft, and a driving gear 4013 is installed on the output shaft. A connecting arm 5 is installed inside the clamping arm mechanism 4. The connecting arm 5 is an L-shaped structure, and the inner A rotating shaft assembly 501 is installed on the part, and the front end of the rotating shaft assembly 501 is fixedly connected to a bevel gear 5011, which meshes with the driving gear 4013 for transmission, and a driving guide 5012 is fixedly connected to the side of the connecting arm 5 away from the clamping arm mechanism 4, and a through groove is provided inside the driving guide 5012, and a bracket assembly 5013 is fixedly connected to the outside of the driving guide 5012. There are two bracket assemblies 5013, and the two bracket assemblies 5013 are fixedly connected to the front and rear side positions of the driving guide 5012 in opposite directions, and a servo motor B5014 is installed on the top surface of the bracket assembly 5013, and an output shaft is provided at the bottom end of the servo motor B5014, and a stepping gear 5015 is installed on the output shaft.

[0034] In this embodiment, when in use, the servo motor A4012 drives the mechanical linkage of the clamping arm to open and close: the servo motor A4012 is vertically installed on the top of the side plate assembly 4011, and its output shaft extends downward and is fixed to the drive gear 4013. The drive gear 4013 has a cylindrical straight tooth structure and forms a vertical meshing with the bevel gear 5011 inside the clamping arm mechanism 4. When the servo motor A4012 is powered on and rotated, the drive gear 4013 drives the bevel gear 5011 to rotate synchronously. The bevel gear 5011 is fixed to the front end shaft section of the rotating shaft assembly 501 through a key connection, thereby driving the rotating shaft assembly 501 to connect. The connecting arm 5 rotates in the bearing hole. The connecting arm 5 is L-shaped, with the end of its horizontal section hinged to the clamping arm assembly 3012, and the vertical section is installed in the longitudinal groove of the clamping arm mechanism 4 through the bearing seat. As the rotating shaft assembly 501 rotates, the horizontal section of the connecting arm 5 swings with the vertical section as the fulcrum, pushing the clamping arm assembly 3012 to open and close along the longitudinal groove of the clamping arm mechanism 4. The arc-shaped clamping portion 3013 on the inner side of the clamping arm assembly 3012 adopts a rubber covering structure. When the clamping arm is closed, the rubber covering tightly fits the outer edge of the aluminum alloy wheel hub, and stable clamping is achieved through the combined action of friction and mechanical clamping force;

[0035] The side plate assembly 4011 is a rectangular steel plate, which is fixed vertically to the front end of the clamping arm mechanism 4 by bolts. Its bottom end is welded to the reinforcement support member 401. The two reinforcement support members 401 are arranged vertically and parallel, and are made of I-section steel. The top end is embedded in the top limit groove of the longitudinal groove of the clamping arm mechanism 4, and the bottom end is fixed to the bottom base plate of the clamping arm mechanism 4 by anchor bolts. This structure forms a rigid support for the front and rear sides of the clamping arm mechanism 4, suppressing the lateral deformation caused by the opening and closing of the clamping arm, and ensuring the stable transmission of the clamping force;

[0036] The driving guide 5012 is a hollow cylindrical structure, and the diameter of its internal through groove is in clearance with the outer diameter of the cylindrical main body of the support mechanism 6. The middle part of the outer side of the support mechanism 6 is fixedly connected to the guide component 601. The guide component 601 is a horizontally protruding rectangular guide plate, and its two ends are embedded in the horizontal sliding groove of the inner wall of the driving guide 5012 to form an axially movable and radially limited sliding pair. The servo motor B5014 is installed on the top of the bracket component 5013. The bracket component 5013 is an L-shaped angle steel. Its vertical section is fixed to the outside of the driving guide 5012 by bolts, and the horizontal section carries the servo motor B5014. The output shaft of motor B5014 extends downward and is fixed to the stepping gear 5015. The stepping gear 5015 engages with the guide gear assembly 6011 inside the guide assembly 601. When the servo motor B5014 rotates, the stepping gear 5015 drives the guide gear assembly 6011 to move along the transverse groove, thereby driving the support mechanism 6 to perform axial feed movement in the through groove of the driving guide 5012. Due to the matching restrictions of the guide assembly 601 and the guide groove 3015, the support mechanism 6 cannot rotate around its own axis during the movement, thereby realizing precise angle adjustment of the aluminum alloy wheel around the central axis of the driving guide 5012.

[0037] Example 2, as Figure 1-Figure 5 As shown, the interior of the driving guide 5012 is plugged with a support mechanism 6, the main body of the support mechanism 6 is a cylindrical structure, and the outer side of the support mechanism 6 is fixedly connected with a guide component 601, the guide component 601 is arranged horizontally, and the guide component 601 is a structure protruding from the support mechanism 6, and there are two guide components 601, which are respectively fixedly connected to the front and rear side positions of the support mechanism 6, and a transverse groove is provided inside the guide component 601, and a guide gear component 6011 is fixedly connected to the interior of the transverse groove, and the guide gear component 6011 and the guide component 601 together constitute a guide structure for the support mechanism 6, and the guide gear component 6011 is engaged with the stepping gear 5015 for transmission.

[0038] In this embodiment, when in use, a slider assembly 3011 is provided on each of the left and right sides of the moving mechanism 3. The slider assembly 3011 consists of a rectangular slider and an embedded ball bearing. The ball bearing rolls along the T-shaped guide groove on the top surface of the guide rail assembly 101. The guide rail assembly 101 is an I-shaped steel beam, which is laterally fixed to the bottom end surface of the support mechanism 1. Its top guide groove and bottom slide groove are used to carry the moving mechanism 3 and the clamping arm mechanism 4 respectively. The adjusting push rod 1013 is an electric push rod, which is provided at two locations, and is arranged laterally along the left and right sides of the support mechanism 1. The left adjusting push rod 1 The fixed end of 013 is hinged to the left side of the support mechanism 1, and the movable end is hinged to the left side of the mobile mechanism 3 through the connecting ear plate; the fixed end of the right adjustment push rod 1013 is hinged to the right side of the support mechanism 1, and the movable end is hinged to the right side of the clamping arm mechanism 4. When the left adjustment push rod 1013 is extended or retracted, it pushes the mobile mechanism 3 to slide laterally along the guide groove on the top surface of the guide rail assembly 101; when the right adjustment push rod 1013 is extended or retracted, it drives the clamping arm mechanism 4 to move synchronously or asynchronously along the sliding groove on the bottom surface of the guide rail assembly 101, thereby adjusting the relative distance between the mobile mechanism 3 and the clamping arm mechanism 4;

[0039] The collar mechanism 2 is a circular steel part, which passes through the connection hole 1012 of the connecting plate 1011 on the top surface of the support mechanism 1. The main lifting rope 201 is a multi-strand steel wire rope, one end of which is fixed to the center of the top surface of the collar mechanism 2, and the other end is connected to the external crane hook. The auxiliary lifting rope 2011 is two steel wire ropes of equal length, symmetrically hinged to the middle of the main lifting rope 201, and the ends thereof are respectively fixed to the lifting ring assembly 2012. The lifting ring assembly 2012 is a shackle with a locking structure, which is detachably connected to the connecting assembly 301 at the top of the mobile mechanism 3 and the clamping arm mechanism 4 with a lifting ear structure. Next, in the initial state, the eye assembly 2012 is locked with the connecting assembly 301, and the moving mechanism 3 and the clamping arm mechanism 4 are suspended below the traveling crane through the collar mechanism 2. When the clamping arm assembly 3012 completes the clamping of the aluminum alloy wheel, the traveling crane slightly lifts the main lifting rope 201 to disengage the eye assembly 2012 and the connecting assembly 301. At this time, the moving mechanism 3 and the clamping arm mechanism 4 are supported by the guide rail assembly 101 and switched to lateral movement driven by the adjusting push rod 1013, thereby avoiding the influence of the flexible deformation of the lifting wire rope on the positioning accuracy.

[0040] The stepping member 3014 at the bottom end of the moving mechanism 3 is a U-shaped guide plate, and its internal guide groove 3015 slides with the guide component 601 on the outside of the support mechanism 6. The guide groove 3015 is dovetail-shaped, and the cross-section of the guide component 601 matches it to form a sliding pair with four-way limit of up, down, left and right. This structure ensures that the moving mechanism 3 is always aligned with the support mechanism 6 as the central axis during the lateral movement process, avoiding deviation caused by installation error of the guide rail component 101 or external force interference, and ensuring the straightness of the aluminum alloy wheel transfer trajectory.

[0041] Example 3, as Figure 2-Figure 8As shown, the outer side of the pillar mechanism 6 is sleeved with a hub part 6012, and the clamping arm mechanism 4, the clamping arm assembly 3012 and the pillar mechanism 6 together constitute a load-bearing and limiting structure for the hub part 6012. A connecting plate part 1011 is fixedly connected to the top surface of the support mechanism 1, and a connecting hole 1012 is opened inside the connecting plate part 1011, and a transversely arranged adjusting push rod 1013 is fixedly connected to the inner side of the guide rail assembly 101. There are two adjusting push rods 1013. The two adjusting push rods 1013 are fixedly connected to the left and right side positions of the support mechanism 1 in opposite directions, and the outer sides of the two adjusting push rods 1013 are respectively fixedly connected to the moving mechanism 3 and the clamping arm mechanism 4, and the inside of the connecting hole 1012 is passed through a ring mechanism 2, and the top of the outer peripheral surface of the ring mechanism 2 is fixedly connected to the main lifting rope 201, and the outer side of the main lifting rope 201 It is fixedly connected with an auxiliary lifting rope 2011, and there are two auxiliary lifting ropes 2011 in total. The two auxiliary lifting ropes 2011 are fixedly connected to the left and right sides of the main lifting rope 201 in opposite directions. The side of the two auxiliary lifting ropes 2011 away from the main lifting rope 201 is fixedly connected with a lifting ring assembly 2012. The top ends of the moving mechanism 3 and the clamping arm mechanism 4 are fixedly connected with a connecting assembly 301 connected to the lifting ring assembly 2012. Two slider assemblies 3011 are fixedly connected to the outside of the moving mechanism 3 in opposite directions. A clamping arm assembly 3012 is fixed on the top surface of the moving mechanism 3. The inner sides of the clamping arm assembly 3012 and the clamping arm mechanism 4 are also fixedly connected with a clamping portion 3013 with an arc-shaped structure. The bottom end of the clamping arm assembly 3012 is fixedly connected with a stepping member 3014 for guiding the support mechanism 6, and a guide groove 3015 is provided inside the stepping member 3014.

[0042] When the wheel is mounted on the support mechanism 6, the top flange contacts the upper surface of the wheel inner ring, and the bottom flange contacts the top surface of the clamping arm 4, thereby forming a two-way limit for the axial movement of the wheel.

[0043] A guide gear assembly 6011 is fixedly installed in the transverse groove of the guide assembly 601. The guide gear assembly 6011 is a rack structure and precisely meshes with the involute tooth profile of the stepping gear 5015. The stepping gear 5015 is fixed to the output shaft of the servo motor B5014 through a key connection. The servo motor B5014 is fixed to the outside of the driving guide 5012 through the bracket assembly 5013. When the servo motor B5014 rotates at a set number of pulses, the stepping gear 5015 drives the guide gear assembly 6011 to move a specific distance, thereby driving the support mechanism 6 to move axially along the driving guide 5012. Due to the rigid connection between the guide gear assembly 6011 and the guide assembly 601, the movement distance of the support mechanism 6 can be precisely controlled by the pulse signal of the servo motor B5014, achieving a positioning effect with an angle adjustment accuracy of 0.1°;

[0044] Quick-replacement structure of modular components: the clamping part 3013 is detachably mounted on the inner side of the clamping arm assembly 3012 and the clamping arm mechanism 4 by bolts. For wheels of different sizes, the clamping module with the corresponding curvature can be replaced. The side panel assembly 4011 is connected to the front end face of the clamping arm mechanism 4 through a transverse slide rail. The slide rail is provided with a plurality of positioning holes. By adjusting the position of the side panel assembly 4011 on the slide rail and inserting the positioning pins, the transverse spacing of the side panel assembly 4011 can be quickly changed to adapt to wheels of different widths.
