Description

Technical Field

[0001] The invention relates to the technical field of electronic throttle valve welding, in particular to a welding tool assembly used for processing electronic throttle valves. Background Art

[0002] Electronic throttle valves are mainly used in automobile engines. When working, they play a role in accurately controlling the intake volume. When accelerating, the throttle opening is increased accordingly according to the degree to which the driver presses the accelerator pedal, so that more air enters the engine to meet the combustion requirements and achieve power output. At the same time, they also have the functions of optimizing fuel economy, improving emission performance and improving driving performance. During the processing of the electronic throttle valve, it is necessary to weld it, and then the welding tooling components for electronic throttle valve processing need to be used. During the welding process of the electronic throttle valve, a large amount of welding slag will be generated. These welding slags need to be collected by the staff after the work is completed. If the welding slag cannot be collected well, the subsequent workload of the staff will increase and the work efficiency of the staff will be reduced. In order to overcome the above defects, prior art 1 (application number is 202411067770.8, application date is 2024-08-06 Chinese patent application) A welding fixture for electronic throttle processing and its working method, when working, it is provided with a material receiving frame, and the falling position of the welding slag is limited by the material feeding frame, and the material receiving frame is in a shaking state, so as to facilitate the rapid discharge of the welding slag. There is also prior art 2 (application number 202410313898.1, application date 2024-03-19 Chinese patent application) A laser welding tooling for electronic throttle fan gear, when working, the air pump uses a tightening ring to vacuum the surface of the laser welder and the electronic throttle to prevent excessive dust from adhering to the surface of the laser welder and the surface of the electronic throttle and affecting the welding quality, and the bottom surface of the dustproof circular plate is slid and scraped after the top arc piece contacts, so as to prevent a large amount of dust from being attached to the bottom surface of the dustproof circular plate by suction and causing blockage and affecting the suction efficiency, thereby reducing the workload of the staff for subsequent cleaning.

[0003] When the welding tool clamps the workpiece and starts welding, not only welding slag will be generated, but also harmful gases will be generated. These harmful gases will affect the operating environment and have a negative impact on the staff. The welding fixture tool in the above application does not have a structure to assist in exhaust gas treatment, which is not conducive to the long-term work of the staff. It not only reduces the work efficiency of the factory, but also affects the health of the staff. Therefore, we propose a welding tool assembly for electronic throttle processing to solve the above-mentioned problems. Summary of the invention

The waste gas treatment component includes a device block which is sleeved and connected to the surface of the connecting rod, and a suction head is fixedly connected to the surface of the device block, and the device block is in a swinging state when working.

[0006] Preferably, the vertical plates are symmetrically distributed on both sides of the working plate, and a motor is bolted to the outer wall of the right vertical plate, and the output end of the motor is fixedly connected to the connecting shaft, and the connecting shaft and the movable plate are threadedly connected.

[0007] Preferably, a limiting shaft is fixedly connected to the inner wall of the vertical plate, and the limiting shaft passes through the interior of the movable plate, and the limiting shaft and the movable plate are slidably connected, and the threads on the left and right sides of the connecting shaft have opposite rotation directions.

[0008] Preferably, the material receiving assembly further comprises a cross bar fixedly connected to the inner wall of the limiting frame, and a protrusion is fixedly connected to the upper surface of the cross bar, and the end of the protrusion is spherical.

[0009] Preferably, the limit plate is viewed from the front as an inverted "L" structure, and a connecting spring having an elastic reset function is fixedly connected to the inner wall of the limit plate, and the other side of the connecting spring is fixedly connected to the lower surface of the limit frame.

[0010] Preferably, the limit frame is a structure that is wide at the top and narrow at the bottom, the protrusions are distributed at equal intervals on the upper surface of the cross bar, and the upper surface of the cross bar is an arc-shaped structure.

[0011] Preferably, the exhaust gas treatment component further comprises an outer convex plate fixedly connected to the outer wall of the vertical plate, and an auxiliary plate is sleeved and connected to the surface of the outer convex plate, and a bottom plate is fixedly connected to the lower surface of the outer convex plate.

[0012] Preferably, the connecting shaft passes through the interior of the vertical plate, and a cam corresponding to the bottom plate is fixedly connected to the surface of the connecting shaft. The auxiliary plate is viewed from the front as an inverted "L" structure, and a column is fixedly connected to the inner wall of the auxiliary plate, and the column passes through the interior of the outer convex plate.

[0013] Preferably, the lower surface of the auxiliary plate is fixedly connected with a lower magnet, both sides of the connecting rod are convex, the upper surface of the equipment block is fixedly connected with a fixed magnet, and the magnetic poles of the upper surface of the fixed magnet are opposite to the magnetic poles of the lower surface of the lower magnet.

[0014] Preferably, a positioning block corresponding to the equipment block is fixedly connected to the outer wall of the vertical plate, and a delivery pipe is fixedly connected to the surface of the equipment block, and the delivery pipe is connected to the input end of the external flue gas treatment device through an external hose.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: a new structural design is adopted. When working, the motor is started, and the motor drives the connecting shaft to rotate, and then the connecting shaft and the limit shaft cooperate to quickly clamp the workpiece through the movable plate and the clamping rod. During the welding process, the limit frame limits the falling position of the debris welding slag, which is convenient for the subsequent cleaning of the staff. At the same time, the adsorption head absorbs the harmful fumes during the welding process to ensure the working environment. In addition, after the welding is completed, when the motor rotates, the limit frame vibrates in the vertical direction under the action of the material receiving assembly, which is convenient for the welding slag to be quickly discharged without leaving any welding slag. At the same time, the adsorption head swings around the connecting rod under the action of the exhaust gas treatment assembly, thereby expanding the adsorption treatment range, which can better absorb and treat the fumes and ensure the working environment. The specific contents are as follows: (1) When the welding tooling assembly for processing the electronic throttle valve is working, the motor is started, and the motor drives the connecting shaft to rotate, and then the movable plates and the clamping rods on the left and right sides are moved closer to each other under the action of the connecting shaft and the limit shaft, and finally the clamping rod clamps the workpiece and fixes it. During the welding process, the limit frame limits the falling position of the welding slag, and the welding slag will not be scattered, which is convenient for the staff to clean the welding slag after the welding is completed, thereby improving the work efficiency.

[0016] Furthermore, the upper surface of the work plate is provided with a position for docking a welding device, which can be docked with a welding robot arm. In addition, the staff can also complete the welding work by manual welding.

[0017] (2) In the welding tooling assembly used for processing the electronic throttle, during the movement of the movable plate and the clamping rod, the movable plate will intermittently contact the protrusion, and then the protrusion, the cross bar and the limit frame will be intermittently pushed and pressed by the movable plate. At this time, the limit frame will make reciprocating linear motion in the vertical direction under the action of the thrust, the limit plate and the connecting spring, and then the limit frame is in a swinging state. At this time, the limit frame can not only limit the falling position of the welding slag, but also prevent debris and welding slag from remaining on its inner wall, thereby improving work efficiency.

[0018] Furthermore, the limit frame itself has a structure that is wide at the top and narrow at the bottom, which facilitates the rapid sliding of welding slag. At the same time, the protrusions are evenly distributed on the upper surface of the cross bar, which speeds up the movement frequency of the limit frame, optimizes the shaking effect, and further optimizes the anti-residue effect.

[0019] (3) During the welding process, the adsorption head of the welding tooling assembly used for processing the electronic throttle valve also works to absorb harmful fumes during the welding process, thereby optimizing the working environment of the staff.

[0020] Furthermore, when the connecting shaft rotates, the connecting shaft will intermittently push the bottom plate through the cam. At this time, the bottom plate and the auxiliary plate make reciprocating linear motion in the vertical direction under the action of the cam thrust, their own gravity, the outer convex plate and the column. Then, the lower magnet on the lower surface of the auxiliary plate will intermittently approach the fixed magnet on the upper surface of the equipment block. Then, the equipment block and the adsorption head rotate around the connecting rod under the action of mutual magnetic force and their own gravity, thereby expanding the working range of the adsorption head and better treating the flue gas.

[0021] Furthermore, when the equipment block and the adsorption head are working, the sucked harmful gases are transported to the flue gas treatment device through the delivery pipe. During the rotation of the equipment block, the positioning block serves to limit the rotation angle of the equipment block, and excessive rotation of the equipment block and the adsorption head will not occur, thereby ensuring the stability of the adsorption head operation.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0025] The present invention provides the following technical solution: a welding tool assembly for processing an electronic throttle.

[0026] Embodiment 1: By setting the movable plate 6 and the clamping rod 7 which can be moved quickly, the workpiece can be clamped and fixed quickly, the working process is simple and fast, and the working efficiency is high. Figure 1-Figure 5 As shown, it includes a working plate 1, a bracket is fixedly connected to the lower surface of the working plate 1, and a vertical plate 2 is fixedly connected to the upper surface of the working plate 1, and a connecting shaft 4 is rotatably arranged inside the vertical plate 2; a movable plate 6 is slidably connected to the surface of the connecting shaft 4, and clamping rods 7 are fixedly connected to the surface of the movable plate 6 at equal intervals; The vertical plates 2 are symmetrically distributed on both sides of the working plate 1, and a motor 3 is bolted to the outer wall of the right vertical plate 2, and the output end of the motor 3 is fixedly connected to a connecting shaft 4, and the connecting shaft 4 and the movable plate 6 are threadedly connected, and a limiting shaft 5 is fixedly connected to the inner wall of the vertical plate 2, and the limiting shaft 5 passes through the interior of the movable plate 6, and the limiting shaft 5 and the movable plate 6 are slidably connected, and the threads on the left and right sides of the connecting shaft 4 have opposite rotation directions.

[0027] During operation, the motor 3 on the surface of the vertical plate 2 is started, and the motor 3 drives the connecting shaft 4 to rotate, and then the movable plates 6 and the clamping rods 7 on the left and right sides are close to each other under the action of the connecting shaft 4 and the limit shaft 5, and finally the clamping rods 7 clamp the workpiece and fix it. The clamping process is simple and convenient, and a position for docking the welding device is provided on the upper surface of the working plate 1, which can dock the welding robot arm. In addition, the staff can also complete the welding work by manual welding.

[0028] Embodiment 2: Different from Embodiment 1, the limit frame 9 is provided to make the welding slag in the welding process easier to collect. In addition, the material receiving assembly is provided to make the limit frame 9 in a shaking state, so that the welding slag is quickly discharged and no welding slag residue will occur. Figure 3 , Figure 5-Figure 6 As shown, the surface of the vertical plate 2 is fixedly connected to the limit plate 8, and a material receiving assembly is provided between the limit plate 8 and the movable plate 6. The material receiving assembly includes a limit frame 9 sleeved and connected to the surface of the limit plate 8. The limit frame 9 moves in the vertical direction when working; The material receiving assembly also includes a cross bar 10 fixedly connected to the inner wall of the limit frame 9, and a protrusion 11 is fixedly connected to the upper surface of the cross bar 10, and the end of the protrusion 11 is spherical. The front view of the limit plate 8 is an inverted "L" structure, and a connecting spring 12 that plays an elastic reset role is fixedly connected to the inner wall of the limit plate 8, and the other side of the connecting spring 12 is fixedly connected to the lower surface of the limit frame 9. The limit frame 9 is a structure that is wide at the top and narrow at the bottom. The protrusions 11 are evenly spaced on the upper surface of the cross bar 10, and the upper surface of the cross bar 10 is an arc-shaped structure.

[0029] During the welding process, the welding slag will directly fall into the interior of the limit frame 9, and the limit frame 9 has a structure that is wide at the top and narrow at the bottom, so the welding slag can be quickly discharged, and during the movement of the movable plate 6, the movable plate 6 will intermittently push the protrusion 11 on the upper surface of the cross bar 10, and when the protrusion 11 is pushed, the limit frame 9 descends under the action of the thrust (the limit plate 8 makes the limit frame 9 move only in the vertical direction), and then the connecting spring 12 is squeezed, and when the movable plate 6 continues to move until it does not push the protrusion 11, the limit frame 9 rises under the action of the connecting spring 12, and the above process is repeated. The limit frame 9 shakes in the vertical direction, and then the limit frame 9 can quickly discharge the welding slag on its inner wall, thereby improving work efficiency.

[0030] Embodiment 3: Different from Embodiment 2, the adsorption head 16 can quickly absorb the harmful gas generated during welding away from the welding site, ensuring the working environment of the staff. At the same time, the equipment block 15 and the adsorption head 16 are in a swinging state when working, with a wider working range and higher working efficiency. Figure 7-10As shown, a connecting rod 14 is fixedly connected to the inner wall of the vertical plate 2, and an exhaust gas treatment component is arranged on the surface of the connecting rod 14. The exhaust gas treatment component includes an equipment block 15 which is sleeved on the surface of the connecting rod 14, and an adsorption head 16 is fixedly connected to the surface of the equipment block 15, and the equipment block 15 is in a swinging state when working. The exhaust gas treatment component also includes an outer convex plate 19 fixedly connected to the outer wall of the vertical plate 2, and an auxiliary plate 20 is sleeved on the surface of the outer convex plate 19, and a bottom plate 21 is fixedly connected to the lower surface of the outer convex plate 19.

[0031] The connecting shaft 4 passes through the interior of the vertical plate 2, and the surface of the connecting shaft 4 is fixedly connected with a cam 13 corresponding to the bottom plate 21. The front view of the auxiliary plate 20 is an inverted "L" structure, and a column 22 is fixedly connected to the inner wall of the auxiliary plate 20, and the column 22 passes through the interior of the outer convex plate 19. The lower surface of the auxiliary plate 20 is fixedly connected with a lower magnet 23, and both sides of the connecting rod 14 are convex. The upper surface of the equipment block 15 is fixedly connected with a fixed magnet 18, and the magnetic poles on the upper surface of the fixed magnet 18 are opposite to the magnetic poles on the lower surface of the lower magnet 23. A positioning block 24 corresponding to the equipment block 15 is fixedly connected to the outer wall of the vertical plate 2, and a delivery pipe 17 is fixedly connected to the surface of the equipment block 15, and the delivery pipe 17 is connected to the input end of the external flue gas treatment device through an external hose.

[0032] During the welding process, the adsorption head 16 is started to absorb the harmful gas in the welding process. During the rotation of the connecting shaft 4, the connecting shaft 4 will drive the cam 13 to rotate synchronously. When the cam 13 rotates, it will intermittently push the bottom plate 21. When the bottom plate 21 is pushed, it will drive the auxiliary plate 20 to rise. When the auxiliary plate 20 rises, the lower magnet 23 will move away from the fixed magnet 18. When the cam 13 continues to rotate away from the bottom plate 21, the bottom plate 21 and the auxiliary plate 20 fall under the action of their own gravity (the outer convex plate 19 makes the auxiliary plate 20 and the bottom plate 21 move only in the vertical direction) At this time, the lower magnet 23 will be close to the fixed magnet 18, and the above process will be repeated. The lower magnet 23 will intermittently approach the fixed magnet 18. At this time, the equipment block 15 and the adsorption head 16 will swing around the connecting rod 14 under the action of mutual magnetic force and their own gravity. At this time, the working range of the adsorption head 16 is increased, the working efficiency is higher, and the flue gas can be better treated. When the equipment block 15 rotates, the positioning block 24 limits the rotation angle of the equipment block 15, and the equipment block 15 and the adsorption head 16 will not rotate excessively, thereby ensuring the working stability of the adsorption head 16.

[0033] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
