Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of actuator motor processing, specifically is a clamping jaw structure for actuator motor wiring terminal welding machine. BACKGROUND
[0002] In the automotive field, the actuator motor is a kind of core component that converts electric energy or hydraulic energy into mechanical energy to realize the conversion of electronic control command to mechanical action. It drives the key components such as engine, transmission and brake system by receiving the signal of electronic control unit (ECU), directly affecting the power output, fuel efficiency, emission level and driving safety of the vehicle. The actuator motor receives the electric signal of ECU through electromagnetic coil, motor or hydraulic device, and converts it into physical motion (such as valve opening and closing, oil pressure adjustment). For example: fuel injector, electronic throttle valve and automatic transmission shift solenoid, etc. The micro motor system (including multiple micro actuators) in modern vehicles has been widely used in electric tailgate, electric seat adjustment and other scenes, significantly improving user experience. In the future, with the popularization of technologies such as drive-by-wire chassis and automatic driving, the actuator motor will play a more critical role in vehicle dynamic control.
[0003] In the field of automatic welding of actuator motor wiring terminal, the welding process puts strict requirements on the precision and reliability of the clamping jaw. For example, in the precision manufacturing scene of automotive electronic components and industrial motors, the arc temperature during welding can reach 800-1200℃, and the high-temperature welding slag splashes on the surface of the clamping jaw, causing the thermal expansion coefficient of the clamping jaw body material to rise and causing local thermal deformation.
[0004] The existing welding clamping jaw is made of high-temperature resistant alloy (such as chromium-molybdenum steel) or ceramic coating for heat insulation. The traditional coating can only slow down heat conduction, but cannot actively dissipate heat. The material performance degrades significantly in long-term high-temperature environment, and even causes deformation to affect the clamping effect. The subsequent maintenance and replacement frequency is high, which is not convenient for enterprises to carry out efficient operation. In addition, the secondary loop current during welding may flow through the clamping jaw body to the transmission structure, causing damage to the transmission components inside the shell, which is not convenient for long-term stable use.

DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0026] In the process of implementation, it is worth pointing out that the shell 1 as the main support part of the whole clamp structure is made of high-strength and high-temperature-resistant metal material, such as aluminum alloy, which has good mechanical properties and heat dissipation performance, can withstand the heat and stress generated during welding, and can ensure the stability of the structure. The welding head 2 is the core component of the welding operation, and the material is generally selected from tungsten, which has high melting point and high hardness, and can maintain stable performance at high temperature to realize accurate welding operation. The transmission block 3 moves towards or away from the driving of the transmission structure inside the shell 1, which can drive the clamp 5 to clamp and loosen the motor terminal of the actuator. The connection between the transmission block 3 and the transmission structure usually adopts high-precision transmission pair, such as ball screw pair, to ensure the stability and accuracy of the movement. The base 4 is used to connect the shell 1 with the actuator motor processing equipment. The clamping jaw 5 composed of multiple clamping pieces 6 can provide convenient conditions for the processing personnel to process the serpentine air duct 7 inside the clamp 5. The design of multiple clamping pieces makes it more flexible to plan the path and layout of the serpentine air duct 7 during processing, ensuring that the air duct can be evenly distributed inside the clamp 5 to achieve the best heat dissipation effect. The clamping piece 6 is made of high-temperature-resistant alloy (such as chromium-molybdenum steel), and the surface close to the welding head 2 is provided with a ceramic heat insulation coating, which can cooperate with the air flow to make the clamp 5 have enough mechanical strength, so that the clamp 5 will not be broken or deformed excessively when bearing a large clamping force and welding stress, and maintain a stable clamping state. The soft sleeve 9 is made of high-temperature-resistant fluororubber material. The serpentine air duct 7, the elbow pipe 10, the hose 11 and the air outlet of the air fan 14 are in communication with each other. The inside of the cavity plate 13 and the air outlet of the air fan 14 and the hose 11 are in communication with each other. The length of the hose 11 is sufficient to meet the needs of the left and right movement of the clamp. The power line of the air fan 14 is electrically connected with the power supply component of the actuator motor processing equipment, which can provide the required electric energy for the air fan 14.
[0027] Further, the edge of the abutting surface between the multiple clamping pieces 6 is provided with a chamfer 23, and the chamfer 23 is welded to form a weld 24. The multiple clamping pieces 6 are fixedly connected through the weld 24.
[0028] In the process of implementation, it is worth pointing out that the chamfer 23 facilitates better filling of the solder during welding, improves the welding quality, and enhances the connection strength between the clamping pieces 6. The formation of the weld 24 requires precise control of welding process parameters such as welding current and welding speed to ensure the uniformity and density of the weld 24, so as to ensure that the multiple clamping pieces 6 can be firmly connected together to form a clamp 5 structure with high overall strength and good heat dissipation performance.
[0029] Further, the clamping jaw 5 is connected with the transmission block 3 through a protection unit, the protection unit comprises: a pair of insulating blocks 15, the insulating blocks 15 are respectively fixedly connected at the bottom ends of the pair of transmission blocks 3, a pair of threaded holes 16 are formed in the lower surfaces of the insulating blocks 15, the bottom end of the clamping jaw 5 is inserted with a pair of bolts 17, the bolts 17 penetrate the clamping jaw 5 and are respectively threadedly connected with the threaded holes 16, and sealing rings 18 are embedded at the bottom ends of the insulating blocks 15 and abut against the top end of the clamping jaw 5.
[0030] In the specific implementation process, it is worth pointing out that the material of the insulating block 15 is selected from hard engineering plastics with excellent insulation performance, such as polytetrafluoroethylene or other hard engineering plastics with excellent insulation performance, which has good insulation, high temperature resistance and corrosion resistance, can effectively isolate the secondary circuit current that may be generated during welding, prevent the current from flowing to the transmission structure in the shell 1, protect the transmission assembly from damage, and the cooperation of the threaded hole 16 and the bolt 17 realizes the reliable connection between the clamping jaw 5 and the insulating block 15, and the connection strength needs to meet the requirements of the clamping force and the welding stress borne by the clamping jaw 5 during welding, and the sealing ring 18 prevents dust, welding slag and other impurities from entering the connection part between the clamping jaw 5 and the insulating block 15, and ensures the sealing and stability of the connection.
[0031] Further, the end of the other side elbow pipe 10 away from the soft sleeve 9 is provided with an auxiliary unit, the auxiliary unit comprises: a circular sheet 22, the circular sheet 22 is located at the end of the other side elbow pipe 10 away from the soft sleeve 9, the contact surface of the circular sheet 22 abuts against the insulating block 15, and a plurality of filter holes 21 are uniformly formed in the front surface of the circular sheet 22.
[0032] In the specific implementation process, it is worth pointing out that the material of the circular sheet 22 is selected from metal materials, such as stainless steel, so as to ensure that it has certain strength and durability, the filter holes 21 can prevent larger impurities from entering the inside of the serpentine air duct 7, the size and distribution of the filter holes 21 need to be reasonably designed according to the actual use environment and air flow requirements, that is, to ensure sufficient filtering effect and to minimize the obstruction to air flow, and the abutting connection between the circular sheet 22 and the insulating block 15 can be realized by arranging elastic washers or the like on the contact surface, so as to ensure the tightness and stability of the connection.
[0033] Further, a plurality of lugs 19 are fixedly connected to the outer wall of the circular sheet 22, screws 20 are inserted into the front surfaces of the lugs 19, and the screws 20 penetrate the lugs 19 and are threadedly connected with the insulating block 15.
[0034] In the implementation process, it is worth noting that the lug 19 and the disc 22 are integrally formed, and the screw 20 can be used to install the disc 22 on the surface of the insulating block 15. The screw 20 is made of high-strength metal material, such as carbon steel, and needs to be surface treated, such as galvanizing, to improve its corrosion resistance. When installing the screw 20, the tightening torque needs to be controlled to ensure that the screw 20 can firmly fix the disc 22 on the insulating block 15, while avoiding damage to the parts due to excessive tightening force.
[0035] Working principle:
[0036] Overall cooperative working principle:
[0037] First, when the motor terminal of the actuator to be welded is transmitted between the two clamping jaws 5, the external equipment control center sends instructions to the transmission structure inside the shell 1. After receiving the instructions, the transmission structure drives a pair of transmission blocks 3 to move towards each other, thereby driving a pair of clamping jaws 5 to precisely clamp the motor terminal of the actuator, preparing for the subsequent welding operation. At this time, the welding head 2 starts to work and welds the clamped motor terminal of the actuator. After welding is completed, the transmission block 3 receives instructions again to drive a pair of clamping jaws 5 to move away from each other, thereby completing the welding operation of the motor terminal of the actuator. This cooperative working mode ensures the automation, efficiency and precision of the welding process.
[0038] Active heat dissipation working principle:
[0039] In this welding operation process, in order to solve the problem of high temperature of the clamping jaw 5 caused by welding, a special heat dissipation device is provided. The operator powers on the air supply fan 14 to make it run. After the air supply fan 14 starts, it sucks in external air and injects it into the internal part of the serpentine air duct 7 through the cavity plate 13, the joint 12, the hose 11 and the one-side elbow pipe 10. The serpentine air duct 7 is cleverly distributed inside the clamping jaw 5. The injected air flow flows in the serpentine air duct 7 and can fully contact with each part of the clamping jaw 5 to absorb the heat generated during the welding process. Then, the air flow after absorbing heat is discharged to the outside through the other side elbow pipe 10, forming a complete air flow circulation. The continuously flowing air flow can directly act on the clamping jaw 5 to effectively remove heat, greatly reducing the probability of high temperature of the clamping jaw 5 during welding operation. During long-term operation, the clamping jaw 5 is not prone to performance degradation and deformation due to high temperature, so it can long and properly hold the motor terminal of the actuator, reducing the frequency of maintenance and replacement of the clamping jaw 5, and providing strong guarantee for the efficient operation of the enterprise.
[0040] Clamping jaw structure and air duct processing principle:
[0041] The clamping jaw 5 adopts a special structure welded by multiple layers of clamping pieces 6, which has many advantages. The clamping jaw 5 composed of multiple layers of clamping pieces 6 provides convenient conditions for the processing personnel to process and set the serpentine air duct 7 inside the clamping jaw 5. The design of multiple layers of clamping pieces makes it possible to plan the path and layout of the serpentine air duct 7 more flexibly during processing, ensuring that the air duct can be evenly distributed inside the clamping jaw 5 to achieve the best heat dissipation effect. At the same time, this structure also ensures the overall strength and stability of the clamping jaw 5, which can withstand a large clamping force and welding stress during welding, ensuring the smooth progress of the welding operation.
[0042] Insulation installation and current protection principle:
[0043] During the installation of the clamping jaw 5 to the transmission block 3, sufficient consideration is given to the electrical safety problem during welding. The insulating block 15 fixedly connected between the clamping jaw 5 and the bottom end of the transmission block 3 closely fits, and the insulating block 15 plays a key role in insulation and isolation. During installation, first, align the through hole at the bottom end of the clamping jaw 5 with the threaded hole 16, then use the bolt 17 to penetrate the clamping jaw 5 and threadedly connect with the threaded hole 16, and complete the installation operation between the clamping jaw 5 and the transmission block 3. Since the insulating block 15 has excellent insulation performance, it can effectively prevent the secondary circuit current from flowing through the clamping jaw 5 to the transmission structure in the housing 1 during welding. In this way, the current can be prevented from damaging the transmission components inside the housing 1, ensuring that the equipment remains in a stable and reliable operating state during long-term use, prolonging the service life of the equipment and reducing the maintenance cost of the enterprise.
[0044] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
