DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution, design method and advantages of the present invention clearer, the present invention is further described in detail by specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] Example 1

[0038] like Figure 1 and Figure 2 As shown, the present invention provides an electronic assembly welding table, including a table 1, a clamping component is arranged on the top of the table 1 for clamping a workpiece, and an adjusting component is arranged at the bottom of the table 1 for adjusting the position of the clamping component; the clamping component includes two hollow grooves opened on the table 1 and symmetrical along the center of the table 1, and limit plates 4 are arranged on the tops of the two hollow grooves, and the two limit plates 4 are respectively slidably connected to the table 1, and the two limit plates 4 move toward each other to complete the clamping of the workpiece; the adjusting component includes a stopper arranged at the center of the bottom of the table 1 A protective box 11, wherein a gear group is arranged inside the protective box, and racks 6 are meshedly connected on both sides of the gear group, and the ends of the two racks 6 extend to the outside of the protective box and are slidably connected to the protective box 11, and the ends of the racks 6 are transmission-connected to the limit plate 4 through a connecting piece, so as to drive the limit plate 4 to move; an adjusting rod 12 is also arranged inside the protective box 11, and one end of the adjusting rod 12 is meshed with the gear group, so as to drive the gear group to rotate, and the other end of the adjusting rod 12 extends to the outside of the table 1 and is provided with a handwheel.

[0039] In the above, a support block 2 is provided on one side of each hollow groove close to the edge of the table top 1, and a movable rod 3 is penetrated in the support block 2. The movable rod 3 is slidably connected to the support block 2, and one end of the movable rod 3 close to the limit plate 4 is connected to the limit plate 4, and the top of the connecting piece passes through the hollow groove and is connected to the movable rod 3.

[0040] like Figure 3 and Figure 4 As shown, the gear set includes a movable shaft 8, a gear 7 and a worm wheel 9; the two ends of the movable shaft 8 are rotatably connected to the top and bottom of the protective box 11 through bearings respectively, and the gear 7 and the worm wheel 9 are both sleeved on the movable shaft 8 and have an interference fit with the movable shaft 8; one end of the adjusting rod 12 located in the protective box 11 is a worm 10 and is rotatably connected to the inner wall of the protective box 11 through a bearing, the worm 10 is meshed with the worm wheel 9, and the gear 7 is meshed with the two racks 6 respectively.

[0041] The existing welding table is not convenient to operate, and it is impossible to quickly clamp and separate the workpiece, which affects the processing efficiency. In this embodiment, the workpiece to be welded is placed at the center of the table 1, and then the adjusting rod 12 is rotated to drive the worm 10 to rotate, and then the movable shaft 8 is driven to rotate through the meshing transmission with the worm wheel 9, and then the gear 7 is driven to rotate. Through the meshing transmission between the gear 7 and the rack 6, the two movable rods 3 can be driven to move in opposite directions through the two connecting parts. When the two movable rods 3 are close to each other, the workpiece can be clamped by the limit plate 4 to ensure the stability of the workpiece during processing. Since the worm 10 and the worm wheel 9 are self-locking, the workpiece will not move easily after being limited.

[0042] Example 2

[0043] On the basis of Example 1, in order to avoid smoke pollution generated during welding, a blind hole is provided at one end of the movable rod 3 near the limit plate 4. The connecting piece in Example 1 includes a connecting pipe 5 and a cross bar. One end of the connecting pipe 5 is connected to the end of the rack 6 through the cross bar, and the other end of the connecting pipe 5 passes through the hollow groove and is connected to the blind hole. The interior of the limit plate 4 is a hollow area 18, and a plurality of smoking holes 17 are provided on the top of the limit plate 4, and the smoking holes 17 are connected to the hollow area 18. The blind hole is connected to the hollow area 18, so that the connecting pipe 5 is connected to the hollow area 18 through the blind hole. A suction fan 13 is provided at the bottom of the table 1, and the suction fan 13 is connected to the connecting pipe 5 through the gas pipe 14. The negative pressure gas generated by the operation of the suction fan 13 can be transmitted to the limit plate 4, and the welding smoke is adsorbed through the smoking holes 17 to avoid harm to the environment and the staff. In order to further improve the adsorption effect, a suction hood 20 is provided outside the suction fan 13 . In the present embodiment, the suction hood 20 is a closed hood, and the air supply pipe 14 is connected to the suction hood 20 .

[0044] like Figure 5 and Figure 6 As shown, in order to prevent dust from entering the inside of the limit plate 4 through the smoking hole 17 when the welding table is not clamped, so that dust accumulates on the bottom side of the limit plate 4, which may affect the subsequent smoking operation, in this embodiment, a connecting plate 16 is provided inside the limit plate 4, and the connecting plate 16 is an inverted L-shaped structure, which is used to block the smoking hole 17; a through hole is opened on one side of the limit plate 4 close to the center of the table 1, and a support rod 15 is provided in the through hole, one end of the support rod 15 is fixedly connected to the connecting plate 16 and the support rod 15 is slidably connected to the through hole; a spring 19 is provided on the side of the connecting plate 16 away from the support rod 15, one end of the spring 19 is connected to the connecting plate 16, and the other end of the spring 19 is connected to the inner wall of the hollow area 18. The connecting plate 16 is fitted with the side wall of the hollow area 18 under the action of the spring 19, and the connecting plate 16 is fitted with the top of the hollow area 18 under the action of the support rod 15.

[0045] After the workpiece is clamped, the side of the workpiece can contact the support rod 15, thereby pushing the support rod 15 to slide in the limit plate 4, pushing the connecting plate 16 to move in the limit plate 4, and releasing the blockage of the smoking hole 17. In this way, during the processing, the suction force can be transmitted to the position of the smoking hole 17 through the operation of the suction fan 13, and the welding smoke is sucked into the limit plate 4 from the smoking hole 17, and then transmitted to the connecting pipe 5 through the blind hole in the movable rod 3, and finally discharged through the air supply pipe 14. This can improve the cleanliness of the processing environment and avoid affecting the welding operation. When the limit plate 4 releases the clamping of the workpiece, the spring resilience can drive the connecting plate to move in the opposite direction and re-block the smoking hole 17. At this time, the connecting plate 16 can block the smoking hole 17 in the non-clamped state, reducing the possibility that dust enters the inside of the limit plate 4 through the smoking hole 17 when the device is not in use, thereby causing dust to accumulate on the bottom side of the limit plate 4, affecting the subsequent smoking operation.

[0046] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or technical improvements in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
