Description

Technical Field

[0001] The invention relates to the technical field of industrial manufacturing equipment, and in particular to a turning device for welding. Background Art

[0002] During the welding process, due to the existence of dead angles at the welding points of some parts, the parts need to be rotated during welding. Generally, the parts are fixed on the loading platform by fixtures. When it is necessary to weld the dead angles of the parts, the parts need to be removed from the original fixtures, and then fixed with other fixtures before welding. At the same time, when welding parts, different welding angles will lead to different welding effects. To obtain the best welding effect, the parts to be welded must first be adjusted to the best angle. In the prior art, in order to solve the welding dead angles and welding effects, multiple sets of fixtures need to be prepared during the welding process of some parts, and welding operations at different positions of the parts are performed on different fixtures. When the fixture needs to be replaced, the parts are constantly disassembled and installed on the fixtures, which invisibly increases the workload of workers and reduces the welding efficiency of parts.

[0017] Furthermore, a reinforcing rib is provided between the fixing base and the second fixing ear.

[0018] The beneficial effects of the present invention are:

[0019] 1) In this device, the worker manually turns the handle, and the handle drives the loading platform to rotate through the main shaft, and the parts to be welded are fixed on the loading platform to form a whole. The rotation of the loading platform directly drives the parts to be welded, and the rotation angle is arbitrary, so it can be adjusted directly according to the welding requirements, which facilitates the workers' welding operations, improves the welding efficiency, and effectively ensures the quality of welded parts.

[0020] 2) The device is provided with a brake disc, a locking assembly and a force-applying assembly. When the loading platform does not need to rotate, the brake disc is directly clamped by the two friction plates on the locking assembly. The clamped brake disc will not rotate, and the loading platform will not rotate either. When the brake disc needs to be loosened, the worker only needs to act on the force-applying assembly with his foot, and the force-applying assembly will drive the two friction plates of the locking assembly to loosen the brake disc. After the brake disc is loosened, the handle can be rotated until the loading platform is in the required position. When the foot relaxes the force-applying assembly, the locking assembly, under the action of the reset spring, causes the two friction plates to re-clamp the brake disc. The whole process is simple to operate, which facilitates the rapid rotation and clamping of the loading platform and saves the time of the loading platform flipping process.

[0021] 3) A limit block and a limit pin are set on the limit support component, so that some welding parts can be rotated to the predetermined position at one time. Because some parts are in the best welding position only after being rotated to a specific position, a limit pin is set at this specific position. When the limit pin contacts the limit block, the loading table is rotated to the best angle, and the parts to be welded on the loading table are also in the best welding position. In this way, workers do not need to find the best position again when welding, which effectively saves a lot of adjustment time for parts welded in batches.

[0022] 4) In this device, a reinforcing rib is provided between the fixed base and the second fixed ear. When the worker's foot acts on the force-applying assembly, the reset spring on the locking assembly will give a reaction force to the second fixed ear. At the same time, the elastic force on the reset spring is transmitted to the friction plate, so that the friction plate can clamp the brake disc. If the second fixed ear falls off from the fixed base, the entire locking assembly will lose its function. Therefore, the reinforcing rib can effectively ensure the stability of the connection between the fixed base and the second fixed ear.

[0023] 5) A limit plate is provided in the force-applying component, and a limit groove cooperating with the pedal rod is provided on the limit plate. When the worker acts on the pedal with his foot, the pedal rod will only move up and down in the limit groove and will not swing left and right. This can protect the worker's legs and prevent the pedal from swinging left and right and causing accidental injury to the worker's legs. BRIEF DESCRIPTION OF THE DRAWINGS

When the handle 5 is rotated, the main rotating shaft 2 connected to the handle 5 will rotate synchronously, and the brake disc 4 and the first adjustment plate 3 arranged on the main rotating shaft 2 will also rotate synchronously, and the first adjustment plate 3 will drive the mounting platform member to rotate synchronously.

[0035] Preferably, two bearing members 6 are arranged on the first support column 1, and both bearing members 6 cooperate with a sleeve 52 arranged on the main rotating shaft 2. The bearing member 6 includes a deep groove ball bearing and a bearing seat, and the bearing seat is fixed on the first support column 1 after adjusting the pad 47. The deep groove ball bearing is arranged in the bearing seat, and a sleeve 52 is arranged on the outside of the main rotating shaft 2. The sleeve 52 is connected to the deep groove ball bearing. The sleeve 52 is arranged to protect the main rotating shaft 2. The deep groove ball bearing can reduce the friction during rotation, and the bearing seat plays a fixing role. Two bearing members 6 are arranged on the first support column 1. The two bearing members 6 strengthen the main rotating shaft 2 during rotation, and the main rotating shaft 2 is more stable during rotation. The two sleeves 52 contacting the two bearing members 6 are coaxially arranged. A first housing 54 is arranged on the first support column 1, and the first housing 54 prevents dust generated during welding from entering the bearing member 6.

[0036] The locking assembly includes a friction plate 7, a fixed base 8, a first connector 9 and a second connector 10. The fixed base 8 is fixedly arranged on the first support column 1, and a first fixing ear 11 and a second fixing ear 12 are arranged on the fixed base 8. The first fixing ear 11 is close to the main shaft 2 and is hinged to the middle of the first connecting rod 13.

The first connecting rod 13 and the second connecting rod 14 both work on the principle of a lever and can rotate around a first axis 23 arranged on the first fixing ear 11. The return spring 20 is always in a compressed state. Under the action of the return spring 20, the first connecting head 9 is subjected to an upward force, and the first connecting head 9 transmits the force to the first connecting rod 13 through the fourth connecting rod 16 and to the second connecting rod 14 through the fifth connecting rod 17, so that the end of the first connecting rod 13 close to the fourth connecting rod 16 and the end of the second connecting rod 14 close to the fifth connecting rod 17 move to both sides, and the first connecting rod 13 and the second connecting rod 14 are both fixed at the first axis 23, so the friction plates 7 arranged on the first connecting rod 13 and the second connecting rod 14 are close to each other, which plays a role in pressing the brake disc 4. The force-applying assembly is connected to the second connecting head 10, and the second connecting head 10 is connected to the first connecting head 9 as a whole through the sliding rod 18. When the force-applying assembly acts, the second connecting head 10 moves downward, which drives the first connecting head 9 to move downward. At this time, the return spring 20 is further compressed, and at the same time, the end of the first connecting rod 13 close to the fourth connecting rod 16 and the end of the second connecting rod 14 close to the fifth connecting rod 17 are close to each other. The first connecting rod 13 and the second connecting rod 14 are both fixed at the first shaft 23, so the friction plates 7 arranged on the first connecting rod 13 and the second connecting rod 14 are away from each other, so as to achieve the purpose of loosening the brake disc 4. A second housing 55 is arranged on the outside of the locking assembly, and the second housing 55 plays a role in protecting the locking assembly to prevent welding shavings from affecting the locking assembly.

A plurality of grooves are provided so that the plurality of connecting rods are subjected to balanced forces during the force-bearing process, and the balanced forces make the respective connecting rods less prone to wear, thereby ensuring that the working process of the locking assembly is carried out smoothly. The first shaft 23 , the second shaft 25 , the third shaft 26 and the fourth shaft 28 are all bolts, and there are no threads at the joints with the connecting rods.

[0038] The force-applying assembly includes a sixth connecting rod 29, a foot pedal 30, a foot pedal rod 31 and a limit plate 32.

When the limit pin 41 contacts the limit block 40, the loading platform 44 is rotated to the best angle, and the parts to be welded on the loading platform 44 are also in the best welding position. In this way, workers do not need to find the best position again when welding, which effectively saves a lot of adjustment time for parts welded in batches. The number and position of the limit pins 41 are adjusted according to the needs of the welding parts. Generally, two limit pins 41 are provided.

Among them, the seventh connecting rod 34 and the limiting plate 32 are both fixedly arranged on the first short moving rod 19.

[0042] Preferably, a reinforcing rib 53 is provided between the fixed base 8 and the second fixed ear 12. A reinforcing rib 53 is provided between the fixed base and the second fixed ear. When the worker's foot acts on the force-applying assembly, the reset spring 20 on the locking assembly will give a reaction force to the second fixed ear 12. At the same time, the elastic force on the reset spring 20 is transmitted to the friction plate 7, so that the friction plate 7 can clamp the brake disc 4.
