Automobile exhaust pipe painting tool

Abstract

The present invention discloses a vehicle exhaust pipe painting tool, which relates to the technical field of vehicle exhaust pipe processing equipment. The tool comprises a base plate, a fixing plate welded to the top of the base plate, and evenly distributed bases fixedly sleeved on the bottom of the base plate. The vehicle exhaust pipe painting tool, through the coordinated use of an air pump, a connecting pipe, an air guide cavity, and a guide rod, enables the vehicle exhaust pipe to be painted to be sleeved on the outside of a set of tooling clamps during operation. The air pump is then started to inject air into the air guide cavity inside the tooling clamps through the connecting pipe, thereby increasing the air pressure in the air guide cavity. Under the action of the air pressure, the two tooling clamps separate toward both sides of the limit column and slide along the guide rod until they contact the inner wall of the vehicle exhaust pipe, thereby clamping and fixing the exhaust pipe on the inner side of the vehicle exhaust pipe and avoiding contact with the outer surface of the vehicle exhaust pipe.

Description

Technical Field

[0001] The invention relates to the technical field of automobile exhaust pipe processing equipment, in particular to an automobile exhaust pipe painting tool. Background Art

[0002] Cars are a common means of transportation in today's society. They are powered by power and are non-track-borne vehicles with four or more wheels. They are mainly used to carry people and (or) goods. The automobile exhaust pipe is one of the important accessories in the car, also known as the automobile exhaust pipe hose. It is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler, making the entire exhaust system flexibly connected, thereby playing a role in reducing vibration and noise, facilitating installation and extending the life of the exhaust and muffler system. It is mainly used in light vehicles, micro vehicles and buses. Its structure is a double-layer corrugated pipe covered with a steel wire mesh sleeve, with straight-edge sections at both ends covered with clips. In order to achieve better muffler effect, the bellows can be equipped with an expansion joint or mesh sleeve. The main material is stainless steel SUS304, and the ferrule and pipe can be made of stainless steel or aluminum-plated steel.

[0003] The role of the car exhaust pipe on the car body is to reduce vibration and noise, and extend the life of the exhaust silencer system. The main material of the exhaust pipe is stainless steel. For ordinary cars, since the exhaust gas of the car is under great pressure when leaving the engine, the noise it produces may make people feel crazy. At this time, the main role of silencer is played by the exhaust pipe of the car. Installing a muffler inside it greatly reduces the noise of the car. Its main working principle is to divert the airflow through multiple channels. These diversions rub and collide with each other, causing the flow rate of the airflow to gradually decrease. This cycle is repeated, and eventually the exhaust gas is discharged through the exhaust pipe of the car, reducing the noise.

[0004] After the automobile exhaust pipe is completed, it needs to be painted on the outside to form a coating and improve the physical properties of the automobile exhaust pipe. During the painting process, the pipe needs to be clamped and fixed. At this time, painting work is needed to assist the work. However, the existing painting tooling still has certain shortcomings in actual use. First, the existing painting tooling actually implements the fixing method of the automobile exhaust pipe mainly by clamping and fixing. The clamping mechanism is clamped on the outside of the exhaust pipe, which is convenient for the staff to paint the outer surface of the pipe. However, this type of painting tooling will cause some areas on the outside of the exhaust pipe to be covered by the clamping mechanism, resulting in the inability to fully carry out the painting work, affecting the painting effect. Secondly, during the painting process of the automobile exhaust pipe, the exhaust pipe needs to be flipped over to facilitate all-round painting of its outside. However, when painting multiple groups of exhaust pipes at the same time, it is difficult to ensure that all automobile exhaust pipes are flipped synchronously, affecting the painting efficiency. For this reason, we designed an automobile exhaust pipe painting tooling to solve the above problems. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a painting tool for automobile exhaust pipes, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a car exhaust pipe painting tool, comprising a base plate, a fixed plate welded on the top of the base plate, and a fixed sleeve on the bottom of the base plate is provided with a uniformly distributed base, a uniformly distributed deflection axis is movably sleeved on the fixed plate, and the outer fixed sleeve of the deflection axis is provided with a socket, two symmetrically distributed tooling splints are movably sleeved in the socket, and an air pump is fixedly installed on the top of the socket, the two tooling splints form a group, and the tooling splints and the air pump are connected by a connecting pipe, the two tooling splints are movably connected with a uniformly distributed socket pipe and a limit column, and an air guide cavity is opened on the inner side of the tooling splint, and a spring is fixedly connected between the limit column and the tooling splint.

[0007] Furthermore, a movable cavity matching the tooling plate is provided in the socket, the left end of the tooling plate is fixedly connected to evenly distributed guide rods, and the outer surface of the tooling plate matches the inner wall of the automobile exhaust pipe.

[0008] Furthermore, the guide rod is located inside the movable cavity, and is slidably connected to the sleeve seat. The end of the guide rod extends to the outside of the sleeve seat and is fixedly sleeved on the limit plate.

[0009] Furthermore, the sleeves are grouped in two, and the two sleeves are symmetrically slidably sleeved on both ends of the limiting column, one end of the sleeve is fixedly connected to the tooling clamping plate, and the spring is sleeved on the inner side of the sleeve.

[0010] Furthermore, the left end of the deflection shaft extends to the outside of the fixed plate and is fixedly sleeved with a synchronous wheel, and a synchronous belt is sleeved between the synchronous wheels.

[0011] Furthermore, a servo motor is fixedly mounted on the left end of the base plate, a bevel gear is fixedly mounted on the outside of the driving shaft of the servo motor, and a bevel gear is mounted on the end of the deflection shaft in the middle, and the two bevel gears are meshed with each other.

[0012] Furthermore, an electric heating plate is fixedly mounted on the bottom plate, and the position of the electric heating plate corresponds to the position of the tooling clamping plate.

[0013] Furthermore, a controller is fixedly installed on the outside of the base plate and the fixed plate, and the controller is electrically connected to the air pump, the servo motor, and the heating plate.

[0014] The present invention provides a painting tool for automobile exhaust pipes, which has the following beneficial effects:

[0015] 1. The automobile exhaust pipe painting tool, through the coordinated use of the air pump and the connecting pipe as well as the air guide cavity and the guide rod, enables the automobile exhaust pipe painting tool to be sleeved on the outside of a set of tooling plywood during operation, and then start the air pump, and the air pump injects air into the air guide cavity inside the tooling plywood through the connecting pipe to increase the air pressure in the air guide cavity. Under the action of the air pressure, the two tooling plywood separate to both sides of the limit column and slide along the guide of the guide rod until they contact the inner wall of the automobile exhaust pipe, thereby achieving clamping and fixing of the exhaust pipe on the inner side of the automobile exhaust pipe, avoiding contact with the outer surface of the automobile exhaust pipe, thereby facilitating the subsequent comprehensive painting of the exterior of the automobile exhaust pipe and improving the painting quality.

[0016] 2. The automobile exhaust pipe painting tool, through the coordinated use of the sleeve tube, the limit column and the spring, makes the automobile exhaust pipe painting tool set with a sleeve tube and the limit column between a group of tooling plywood. The two sleeve tubes are movably sleeved on the outside of the limit column. The limit column and the tooling plywood are fixedly connected with a spring. When the tooling plywood is clamped under the action of the air pump, the tooling plywood drives the sleeve tube to move toward the two ends of the limit column and stretches the spring at the same time. After completing the clamping and painting work, the air pump discharges the air in the air guide cavity inside the tooling plywood, and the tooling plywood and the sleeve tube are reset under the action of the spring elastic force, releasing the clamping and fixation of the automobile exhaust pipe, making the operation of the automobile exhaust pipe painting tool for disassembling the automobile exhaust pipe simple and convenient.

[0017] 3. The automobile exhaust pipe painting tooling uses a servo motor and a bevel gear as well as a synchronous wheel and a synchronous belt in coordination. When the automobile exhaust pipe painting tooling is performing batch painting, the automobile exhaust pipe is sleeved on the outside of the tooling clamping plate, the servo motor is started and drives the bevel gear on the outside of its output shaft to rotate, and then drives the middle deflection shaft and the synchronous wheel to rotate through the engagement between the two sets of bevel gears. During the rotation of the synchronous wheel, all the deflection shafts are driven to deflect together through the synchronous belt, thereby realizing the rotation of the sleeve seat and the external structure of the sleeve seat, realizing the adjustment of the paint spraying position of the automobile exhaust pipe during the painting process, ensuring that when multiple groups of exhaust pipes are sprayed synchronously, all automobile exhaust pipes can be flipped synchronously, facilitating batch processing and improving painting efficiency.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] See also Figures 1 to 5 The present invention provides a technical solution: a car exhaust pipe painting tool, comprising a base plate 1, a fixing plate 2 welded to the top of the base plate 1, the base plate 1 and the fixing plate 2 are used to assist in the fixation of other mechanisms, and can be made of iron metal with strong load-bearing capacity, and the bottom fixed sleeve of the base plate 1 is provided with a uniformly distributed base 13, the base 13 is used to make the tool as a whole, and can be made of hard rubber to improve a certain degree of seismic resistance, a uniformly distributed deflection shaft 15 is movably sleeved on the fixing plate 2, and the outer fixed sleeve of the deflection shaft 15 is provided with a socket 10, and an active cavity 14 matching the tooling splint 3 is opened in the socket 10, and the active cavity 14 opened in the socket 10 can facilitate the movement of the tooling splint 3, providing a certain activity space for the tooling splint 3.

[0028] The left end of the tooling splint 3 is fixedly connected with an evenly distributed guide rod 11, which can assist in guiding the tooling splint 3 during its movement, and the outer surface of the tooling splint 3 matches the inner wall of the automobile exhaust pipe. The tooling splint 3 fixes the exhaust pipe on the inner wall of the automobile exhaust pipe, so the outer surface of the tooling splint 3 needs to match the inner wall of the automobile exhaust pipe. The guide rod 11 is located on the inner side of the movable cavity 14, and the guide rod 11 is slidingly connected to the socket 10. The guide rod 11 provides guidance for the movement process of the tooling splint 3. The end of the guide rod 11 extends to the outside of the socket 10 and is fixedly mounted with a limit plate. The limit plate at the end of the guide rod 11 can assist in limiting the range of movement of the tooling splint 3.

[0029] See also Figures 3 to 7 , the sleeve seat 10 is equipped with two symmetrically distributed tooling plates 3, and an air pump 4 is fixedly installed on the top of the sleeve seat 10. The two tooling plates 3 are a group, and the tooling plates 3 and the air pump 4 are connected through a connecting pipe 16. When the air pump 4 is started, the air pump 4 can inject air into the air guide cavity 18 inside the tooling plates 3 through the connecting pipe 16. The two tooling plates 3 are movably connected with evenly distributed sleeve pipes 17 and limit columns 19 to enhance the air pressure in the air guide cavity 18 , the two tooling splints 3 are separated to both sides of the limit column 19 under the action of air pressure. The principle and use process of this 4 are the same as the existing technology and will not be repeated here. An air guide cavity 18 is opened on the inner side of the tooling splint 3, and two sleeve tubes 17 are a group of two, and the two sleeve tubes 17 are symmetrically slidably connected to the two ends of the limit column 19. When the tooling splint 3 is clamped under the action of the air pump 4, the tooling splint 3 can drive the sleeve tube 17 to move to the two ends of the limit column 19, while stretching the spring 20.

[0030] One end of the sleeve tube 17 is fixedly connected to the tooling splint 3, and the spring 20 is sleeved on the inner side of the sleeve tube 17. After completing the clamping and painting work, the air pump 4 discharges the air in the air guide cavity 18 inside the tooling splint 3, and the tooling splint 3 and the sleeve tube 17 are reset under the action of the spring 20. The spring 20 is fixedly connected between the limit column 19 and the tooling splint 3. The left end of the deflection shaft 15 extends to the outside of the fixed plate 2 and is fixedly sleeved with a synchronous wheel 5. A synchronous belt 8 is sleeved between the synchronous wheels 5. The sleeve seat 10 can deflect around the deflection shaft 15 on the outside of the fixed plate 2. The synchronous wheel 5 and the synchronous belt 8 are docked through teeth and grooves. When the two rotate, they can drive all the deflection shafts 15 to rotate, thereby realizing the deflection adjustment of the automobile exhaust pipe.

[0031] See also Figures 1 to 4The left end of the base plate 1 is fixedly fitted with a servo motor 6, and the outside of the drive shaft of the servo motor 6 is fixedly fitted with a bevel gear 7. The servo motor 6 starts and drives the bevel gear 7 outside its output shaft to rotate, and then drives the middle deflection shaft 15 and the synchronous wheel 5 to rotate through the engagement between the two sets of bevel gears 7. The end of the middle deflection shaft 15 is fitted with a bevel gear 7, and the two bevel gears 7 are engaged with each other. During the rotation of the synchronous wheel 5, all the deflection shafts 15 are driven to deflect together through the synchronous belt 8. An electric heating plate 12 is fixedly installed on the base plate 1, and the electric heating plate 12 can emit high temperature above it when working.

[0032] The position of the electric heating plate 12 corresponds to the position of the tooling clamp 3, and the outside of the automobile exhaust pipe that is deflected after the painting process is completed is dried to promote the rapid shaping of the coating. The controller 9 is fixedly installed on the outside of the base plate 1 and the fixed plate 2. The controller 9 can control the operation and stop of each device in the entire device, so that the air pump 4, servo motor 6, and electric heating plate 12 can cooperate with each other to complete the work. The controller 9 is electrically connected to the air pump 4, servo motor 6, and electric heating plate 12 to ensure the intelligence of the automobile exhaust pipe painting tooling during use. The principle and use process of this controller 9 are the same as those in the prior art and will not be repeated here.

[0033] In summary, when the automobile exhaust pipe painting tool is used, the automobile exhaust pipe to be painted is sleeved on the outside of the tooling splint 3, the controller 9 is operated to control the overall operation of the device, and the air pump 4 is started. The air pump 4 injects air into the air guide cavity 18 on the inner side of the tooling splint 3 through the connecting pipe 16 to increase the air pressure in the air guide cavity 18. The two tooling splints 3 are separated to the two sides of the limit column 19 under the action of the air pressure, and slide along the guide rod 11 in the movable cavity 14 inside the socket 10 until they contact the inner wall of the automobile exhaust pipe, thereby fixing the automobile exhaust pipe. When the tooling splint 3 is clamped under the action of the air pump 4, the tooling splint 3 drives the sleeve pipe 17 to move toward the two ends of the limit column 19, and at the same time stretches the spring 20. After the automobile exhaust pipe is fixed, the outside of the exhaust pipe is sprayed with paint. During the painting process, the servo motor The machine 6 starts and drives the bevel gear 7 outside its output shaft to rotate, and then drives the deflection shaft 15 and the synchronous wheel 5 in the middle to rotate through the meshing between the two sets of bevel gears 7. During the rotation of the synchronous wheel 5, all the deflection shafts 15 are driven to deflect together through the synchronous belt 8, thereby realizing the rotation of the socket 10 and the external structure of the socket 10, thereby realizing the adjustment of the paint spraying position of the automobile exhaust pipe during the painting process. At the same time, the electric heating plate 12 dries the outside of the deflected automobile exhaust pipe to promote rapid shaping of the coating. After completing the clamping and painting work, the air pump 4 discharges the air in the air guide cavity 18 inside the tooling splint 3, and the tooling splint 3 and the sleeve pipe 17 are reset under the action of the elastic force of the spring 20, thereby releasing the clamping and fixation of the automobile exhaust pipe, and directly removing the processed automobile exhaust pipe, completing the use process of the entire automobile exhaust pipe painting tooling.
