[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1 to 3 This utility model provides a welding fixture for facilitating the positioning of cable tray support arms. It includes a welding table 1, with two vertical plates 3 connected to the top of the welding table 1. The vertical plates 3 are vertically arranged and connected to two baffles 6, which are perpendicular to the vertical plates 3. A base 5 is placed between two clamping plates 12, and the support arm body 4 is placed inside the two baffles 6 and fitted against the vertical plates 3, achieving initial positioning of the support arm body 4 and facilitating precise pressing of the pressure plate 7 into the support arm body 4. The welding table 1 is connected to a positioning mechanism for positioning the support arm body 4. The positioning mechanism includes two pressure plates 7, a toothed plate 15, and a cylinder 21. The cylinder 21 drives the toothed plate 15 to reciprocate. The pressure plates 7 are connected to the toothed plate 15 and match the groove inside the support arm body 4. The toothed plate 15 is connected to a clamping mechanism for clamping the base 5.
[0021] The main body 4 of the support arm is a C-shaped steel with an a-side inside. When the main body 4 of the support arm is in the positioning state, the pressure plate 7 presses against the a-side to keep the main body 4 of the support arm vertical.
[0022] After the support arm body 4 and base 5 are placed, cylinder 21 drives toothed plate 15 to move forward, simultaneously moving moving plate 9, connecting plate 8, and two pressure plates 7 forward. At the same time, the forward movement of toothed plate 15 drives gear 16 to rotate, thereby rotating stud 20, causing the two corresponding sliding blocks 18 to move closer to each other. Sliding blocks 18 drive push plate 11 to move, push plate 11 drives clamping plate 12 to move, and the two clamping plates 12 clamp onto base 5. Pressure plates 7 press against the inside of support arm body 4, achieving complete locking and fixing of the two support arms, improving the stability of the support arms, increasing efficiency, and saving time and effort in operation.
[0023] The positioning mechanism also includes a connecting plate 8, a movable plate 9, and a fixed seat 22. The two ends of the connecting plate 8 are connected to the pressure plate 7, the two ends of the movable plate 9 are connected to the toothed plate 15 and the connecting plate 8, the fixed seat 22 is fixed to the bottom of the welding table 1, the cylinder 21 is fixed to the fixed seat 22, and the power output end of the cylinder 21 is connected to the toothed plate 15.
[0024] The movable plate 9 and the toothed plate 15 are slidably connected to the welding table 1, which improves the stability of the reciprocating movement of the movable plate 9 and the toothed plate 15, and thus guides the connecting plate 8 and the two pressure plates 7.
[0025] The clamping mechanism includes two bearing seats 17, four sliding blocks 18, studs 20, gears 16, four push plates 11, four clamping plates 12, multiple springs 13, and multiple guide posts 14. The bearing seats 17 are used to guide the studs 20. The studs 20 are used to drive the corresponding two sliding blocks 18 to move closer or further away from each other. The gears 16 are fixedly connected to the studs 20 and connected to the gear plate 15. The sliding blocks 18 are fixed to the ends of the push plates 11. One end of the guide post 14 is connected to the clamping plate 12 and the guide post 14 passes through the push plate 11. The springs 13 are sleeved on the guide posts 14 and both ends of the springs 13 are connected to the other ends of the push plates 11 and the guide posts 14.
[0026] When the two clamping plates 12 are connected to the base 5, the pressure plate 7 is inserted into the support arm body 4, but does not contact the inner side of the support arm body 4. The cylinder 21 continues to drive the toothed plate 15 forward, so that the two clamping plates 12 are gradually pressed against the base 5, and the spring 13 is gradually compressed until the pressure plate 7 is pressed against the inner side (a side) of the support arm body 4, and the two clamping plates 12 are clamped against the base 5, realizing the complete locking and fixing of the support arm, which facilitates subsequent welding operations.
[0027] The bearing housing 17 is connected to the bottom of the welding table 1, and the end of the stud 20 is rotatably connected to the bearing housing 17, which improves the stability of the stud 20 rotation, makes the gear 16 rotate steadily, and ensures the effectiveness of the transmission between the gear 16 and the gear plate 15.
[0028] Gear 16 meshes with toothed plate 15, resulting in high transmission efficiency and ensuring a constant instantaneous transmission ratio.
[0029] The stud 20 is threadedly connected to the two corresponding sliding blocks 18, and the internal threads of the two sliding blocks 18 are in opposite directions.
[0030] The welding table 1 is provided with a sliding hole 10, and a sliding block 18 is slidably connected to the sliding hole 10. The sliding block 18 slides within the sliding hole 10, which improves the stability of the push plate 11 movement.
[0031] The clamping plate 12 has a V-shaped structure. The two clamping plates 12 are gradually pressed onto the base 5 to facilitate the adjustment of the position of the base 5 so that the base 5 is in a suitable position. At this time, the position refers to the relative position of the base 5 and the support arm body 4.
[0032] The top of the welding table 1 is connected to two L-shaped seats 2, and the vertical plate 3 is fixed to the end of the L-shaped seats 2.
[0033] Working principle: The base 5 is placed between two clamping plates 12, and the support arm body 4 is placed inside two baffles 6, connected to the top of the base 5 and the front end of the vertical plate 3. The cylinder 21 drives the toothed plate 15 to move forward, simultaneously driving the moving plate 9, connecting plate 8, and two pressure plates 7 to move forward. At the same time, the forward movement of the toothed plate 15 drives the gear 16 to rotate, and the gear 16 simultaneously drives the stud 20 to rotate, causing the corresponding two sliding blocks 18 to move closer to each other. The sliding blocks 18 drive the push plate 11 to move, realizing the movement of the clamping plate 12. When the clamping plate 12 clamps the base 5, the spring 13 is in a compressed state, and the pressure plate 7 is pressed against surface a, realizing the complete locking and fixing of the support arm, which is highly efficient and facilitates welding operations at the connection between the support arm body 4 and the base 5. After welding is completed, cylinder 21 drives toothed plate 15 to move backward, causing moving plate 9, connecting plate 8 and two pressure plates 7 to move backward. Pressure plate 7 separates from baffle 6. The backward movement of toothed plate 15 drives gear 16 and stud 20 to rotate, causing the corresponding two sliding blocks 18 to move away from each other, that is, the corresponding two push plates 11 to move away from each other. Clamping plate 12 separates from base 5, thereby loosening the support arm. Then the support arm can be moved out.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
