A translation mechanism

Abstract

The present invention provides a translation mechanism, belonging to the technical field of welding torches. The translation mechanism includes a connecting plate and a lead screw arranged on the connecting plate. A guide rod is further arranged on the lead screw. An installation component is slidably connected to the guide rod. There is a frictional force between the installation component and the guide rod through a friction component. A sliding component that slides horizontally is arranged inside the installation component. The lead screw is threadedly connected to the installation component and the sliding component; when the installation component moves, first, the lead screw rotates to drive the sliding component to move. Due to the frictional force between the installation component and the guide rod through the friction component, when the sliding component moves, the elastic component can buffer the movement of the sliding component driving the installation component. When the lead screw stops rotating, the elastic component will push the installation component to move a short distance, thereby preventing the loosening of the welding torch on the installation component caused by the instant start and stop of the installation component.

Driving components are installed at both ends of the lead screw, the lead screw is installed on the frame, the lead screw nut is installed on the lead screw, the lead screw nut is connected to the moving plate, and mechanisms for the vertical movement and rotational movement of the welding torch are installed on the moving plate. The moving plate guide rail is fixed on the frame. During operation, according to the process requirements, the driving component is actuated to make the lead screw nut move on the lead screw. The lead screw nut drives the moving plate, causing the moving plate to move along the guide rail to a specified position for welding operation.

[0003] However, when the existing translation mechanism starts or stops, the driving component will instantaneously drive the welding torch to move or stop. The welding torch will vibrate on the mounting component due to inertia. Over time, the welding torch will become loose on the mounting component, and in addition, it will also affect the accuracy of the welding torch. Summary of the Invention

[0004] The purpose of the present invention is to provide a translation mechanism, aiming to solve the problems in the prior art that the welding torch does not have a buffering effect when moving or stopping, the welding torch will become loose on the mounting component over time, and in addition, it will also affect the accuracy of the welding torch.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A translation mechanism, comprising: a connecting plate and a lead screw arranged on the connecting plate. A guide rod is further arranged on the lead screw. A mounting component is slidably connected to the guide rod. There is a frictional force between the mounting component and the guide rod through a friction component. A sliding component that slides horizontally is arranged inside the mounting component. The lead screw is threadedly connected to the mounting component and the sliding component. An elastic member that pushes the sliding component to the middle of the mounting component is arranged inside the mounting component.

[0006] In order to enable the translation mechanism to have the effect of having a frictional force between the mounting component and the guide rod, as a preferred embodiment of the present invention, the friction component includes a connecting rod that rotates on the sliding component. One end of the connecting rod away from the sliding component is rotatably connected to a top plate that abuts against the guide rod. The top plate slides up and down inside the mounting component.

[0007] In order to enable the translation mechanism to have the effect of keeping the sliding component off-center, as a preferred embodiment of the present invention, a telescopic cylinder connected to the mounting component is arranged on the sliding component. Vent holes are arranged on the telescopic cylinder. A blowing component is arranged on the sliding component. The lead screw drives the blowing component to operate through a transmission component.

[0008] In order to enable this translation mechanism to have a blowing function, as a preferred embodiment of the present invention, the blowing component includes a fan disposed inside two telescopic cylinders, and the two fans are coaxially connected by a connecting shaft.

[0009] In order to enable this translation mechanism to have a function of driving the blowing component, as a preferred embodiment of the present invention, the transmission component includes a rotating shaft rotatably disposed on the sliding component, the rotating shaft and the connecting shaft are connected by a belt, a gear is disposed on the rotating shaft, and a tooth groove adapted to the gear is provided along the axial direction of the lead screw.

[0016] 1. For this translation mechanism, when the installation component moves, first, the lead screw rotates to drive the sliding component to move. Since there is a frictional force between the installation component and the guide rod through the friction component, when the sliding component moves, the elastic member can buffer the movement of the installation component driven by the sliding component. When the lead screw stops rotating, the elastic member will push the installation component to move a short distance, thereby preventing the instant start and stop of the installation component from causing the welding torch on the installation component to become loose.

[0017] 2. For this translation mechanism, by sliding the sliding component inside the installation component, the friction component can be moved downward, reducing the frictional force between the installation component and the guide rod, thereby reducing the power of the driving device and the power consumption of the driving device.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-3, the present invention provides the following technical solution: A translation mechanism, comprising: a connecting plate 1 and a lead screw 2 disposed on the connecting plate 1. The connecting plate 1 can be connected to the body of the device. A guide rod 3 is also disposed on the lead screw 2. The lead screw 2 and the guide rod 3 are arranged in the same axial direction. An installation component 4 is slidably connected to the guide rod 3. The installation component 4 can be used to install a welding torch head. There is a frictional force between the installation component 4 and the guide rod 3 through a frictional component 7. The frictional component 7 is disposed inside the installation component 4. A sliding component 5 that slides horizontally is disposed inside the installation component 4. There is a chamber inside the installation component 4. The sliding component 4 slides inside the chamber, and the side wall of the sliding component 4 is limited by the side wall of the chamber, so that the sliding component 4 can only slide horizontally inside the installation component 4. The lead screw 2 is threadedly connected to the installation component 4 and the sliding component 5. When the lead screw 2 rotates, it can drive the sliding component 5 to move. An elastic member 6 that pushes the sliding component 5 to be located in the middle of the installation component 4 is disposed inside the installation component 4. Through the elastic member 6, the sliding component 5 can be reset, so that the sliding component 5 is reset to the middle of the installation component 4.

[0028] In a specific embodiment of the present invention, when the installation component 4 moves, first, the lead screw 2 rotates to drive the sliding component 5 to move. Since there is a frictional force between the installation component 4 and the guide rod 3 through the frictional component 7, when the sliding component 5 moves, the elastic member 6 can buffer the movement of the installation component 4 driven by the sliding component 5. When the lead screw 2 stops rotating, the elastic member 6 will push the installation component 4 to move a short distance, thereby preventing the welding torch from loosening on the installation component 4 due to the instantaneous start and stop of the installation component 4.

[0029] Specifically, please refer to Figure 3 , the frictional component 7 includes a connecting rod 71 that rotates on the sliding component 5. One end of the connecting rod 71 away from the sliding component 5 is rotatably connected to a top plate 72 that abuts against the guide rod 3. The top plate 72 slides up and down inside the installation component 4. When the sliding component 5 moves inside the installation component 4, the top plate 72 can be pulled downwards through the connecting rod 71, so that the top plate 72 does not contact the guide rod 3. When the sliding component 5 is located in the middle of the installation component 4, the connecting rod 71 pushes the top plate 72 to contact the guide rod 3, thereby increasing the frictional force between the installation component 4 and the guide rod 3.

[0030] Specifically, please refer to Figures 3-4, a telescopic cylinder 8 connected to the mounting member 4 is provided on the sliding member 5. The inside of the telescopic cylinder 8 is hollow. An air vent 81 is provided on the telescopic cylinder 8. When the telescopic cylinder 8 expands and contracts, air can enter and exit through the air vent 81. A blowing member 9 is provided on the sliding member 5, and the exhaust volume of the blowing member 9 is greater than the ventilation volume of the air vent 81. The blowing member 9 can form a negative pressure state or a positive pressure state inside the telescopic cylinder 8. Thus, when one end of the elastic member 6 is in an energy storage state, the blowing member 9 can extract the air inside the telescopic cylinder 8, causing the telescopic cylinder 8 to contract, so that the elastic member can be kept in a compressed state. The lead screw 2 drives the blowing member 9 to operate through the transmission member 10. When the lead screw 2 rotates, it can drive the blowing member 9 to operate. The direction in which the lead screw 2 drives the sliding member 5 to move is consistent with the position of the telescopic cylinder 8 to be telescoped. The operation of the blowing member 9 can cause the relative telescopic cylinder 8 to expand and contract, keeping the elastic member 6 in a compressed state, causing the sliding member 5 to be in a state deviated from the center of the mounting member 4. Furthermore, the friction member 7 is in a state of being disengaged from the contact with the guide rod 3, and the friction between the mounting member 4 and the guide rod 3 is reduced, thereby reducing the power of the driving member and the power consumption of the driving member. When the lead screw stops operating, the blowing member 9 stops operating, and the elastic member pushes the telescopic cylinder 8 to reset. At the same time, the ventilation cylinder 81 intakes or exhausts air, and the sliding member 5 also resets through the elastic member 6.

[0031] Specifically, please refer to Figure 5 , the blowing member 9 includes fans 91 provided inside two telescopic cylinders 8. The two fans 91 are coaxially connected by a connecting shaft 92. When the connecting shaft 92 rotates, it can drive the two fans 91 to rotate simultaneously.

[0032] Specifically, please refer to Figure 4 , the transmission member 10 includes a rotating shaft 101 rotatably mounted on the sliding member 5. The rotating shaft 101 and the connecting shaft 92 are connected by a belt 102. A gear 103 is provided on the rotating shaft 101. The lead screw 2 is provided with a tooth groove 104 adapted to the gear 103 along the axial direction. Through the cooperation between the gear 103 and the tooth groove 104, the rotation of the lead screw 2 can drive the gear 103 to rotate. The gear 103 can drive the rotating shaft 101 to rotate. The rotating shaft 101 can drive the connecting shaft 92 to rotate through the belt 102, thereby driving the fan 91 to rotate.

[0033] Furthermore, a rubber pad is provided on the top plate 72 and the guide rod 3. By providing the rubber pad, the friction with the guide rod 3 can be increased.

[0034] Furthermore, a driving device 11 for driving the lead screw 2 to rotate is provided on one side of the connecting plate 1. The operation of the driving device 11 can drive the lead screw 2 to rotate.

[0035] Preferably, the driving device 11 is a motor.

[0036] Preferably, the elastic member 6 is a compression spring.

[0037] Furthermore, an installation disc is provided at the top of the installation component 4, and the installation disc can be used to install a welding torch head.
