Description

Technical Field

[0001] The invention belongs to the technical field of guide rail processing, in particular to a turning device for guide rail welding. Background Art

[0002] Guide rails are key components in mechanical systems that support and guide moving parts along specific paths for linear or curved motion. They are widely used in industrial automation, robotics, transportation, and precision machinery. The accuracy, stiffness, and wear resistance of guide rails have an important impact on the operating stability and service life of the system. With the advancement of science and technology, the design and manufacturing technology of guide rails are constantly optimized to meet the growing accuracy requirements and complex application scenarios.

[0003] In the guide rail welding operation, the traditional flipping device has many problems that need to be solved. First, for the welding of large or heavy guide rails, the existing flipping device cannot simultaneously flip two guide rails at the same time, and when the two sections of the guide rails are not aligned, flip one guide rail separately to adjust the welding surface, which makes the two sections of the guide rails need to be flipped synchronously to ensure the alignment of the welding surface. The operation is complicated and time-consuming, which seriously affects the welding efficiency. At the same time, when there is a slight deviation in the alignment of the guide rail welding surface, the traditional device often cannot provide fine-tuning function, resulting in difficulty in ensuring welding accuracy. In addition, during the flipping process, the guide rail may cause the rotating ring to rotate due to the unstable center of gravity, thereby increasing the burden on the internal tooth groove and the transmission gear, which is easy to cause damage. At the same time, when the drive shaft is subjected to a large torque, it may also produce excessive pressure on the output shaft of the AC motor, affecting the stability and durability of the motor.

At the same time, the No. 2 brake lock assembly, under the linkage of the No. 1 brake lock assembly, locks the drive shaft, reduces the pressure on the output shaft of the AC motor from the source, provides additional locking for the drive shaft, and further improves safety and durability.

DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1:

[0036] See also Figure 1-Figure 7The present application provides a flipping device for guide rail welding, comprising a base plate 1, a frame body 2 is fixedly connected to the base plate 1, and a flipping unit 3 is arranged on the frame body 2; the flipping unit 3 comprises a support plate 33, and a differential assembly 34 is arranged on the support plate 33, and the differential assembly 34 comprises a rotatable driven gear 343, which can drive two drive shafts 36 to rotate simultaneously, so as to facilitate the simultaneous flipping of two sections of guide rails, and a connecting plate 345 is eccentrically arranged on both sides of the driven gear 343, and each of the connecting plates 345 is connected to a first bevel gear 347 through a second rotating shaft 346, and the rotation of the first bevel gear 347 can not be affected in the rotation process of a single section of the driving shaft 36, and the first bevel gear 347 is meshedly connected with a second bevel gear 348, and the flipping unit 3 also comprises a rotatable driving shaft 36, a supporting frame is fixedly connected to the frame 2, and the driving shaft 36 is rotatably connected to the supporting frame for providing support to the driving shaft 36, and the frame 2 An AC motor 38 is connected through the No. 2 motor frame 37, and two AC motors 38 are provided. The output end of each AC motor 38 is fixedly connected to the corresponding driving shaft 36 for driving the driving shaft 36 to rotate. Each No. 2 bevel gear 348 is fixedly connected to the corresponding driving shaft 36. The flip unit 3 also includes a driving motor 32 connected to the frame body 2 through the No. 1 motor frame 31. The output end of the driving motor 32 is fixedly connected to the No. 1 rotating shaft 341. The No. 1 rotating shaft 341 is fixedly connected with a driving gear 342 for driving the driven gear 343 to rotate. A support plate 33 is fixedly connected to the frame body 2. The driven gear 343 is provided with a No. 1 annular groove 344, and the lower end of the support plate 33 is slidably connected to the inside of the No. 1 annular groove 344. It should be noted that the purpose of providing the support plate 33 and the No. 1 annular groove 344 is to provide support for the driven gear 343 while ensuring the rotation of the driven gear 343.

[0037] In this embodiment, the flipping unit 3 also includes two groups of flipping components 39; each group of the flipping components 39 includes an arc-shaped support platform 391 fixedly connected to the base plate 1, which plays a supporting role, and a No. 2 annular groove 392 is arranged on the arc-shaped support platform 391, and a rotating ring 393 is slidably connected inside the No. 2 annular groove 392, which can drive the guide rail to flip, and an inner tooth groove 394 is arranged on the inner wall of the rotating ring 393; each of the driving shafts 36 is provided with a No. 1 transmission gear 395 respectively meshing with the inner tooth groove 394, which is used to drive the rotating ring 393 to slide and rotate inside the No. 2 annular groove 392.

[0038] In this embodiment, each of the rotating rings 393 is provided with a clamping claw 396 for clamping the fixed guide rail to ensure its stability during the welding process.

[0039] Specifically, by starting the driving motor 32, the No. 1 rotating shaft 341 can be driven to rotate, and the No. 1 rotating shaft 341 drives the driving gear 342 to rotate, thereby causing the driven gear 343 to rotate, and the driven gear 343 drives the connecting plates 345 on both sides thereof to rotate, and each connecting plate 345 drives the No. 1 bevel gear 347 to rotate around the No. 2 bevel gear 348 through the No. 2 rotating shaft 346, thereby respectively driving the two No. 2 bevel gears 348 to rotate, and the No. 2 bevel gear 348 drives the driving shaft 36 to rotate, thereby realizing that the flip assembly 39 equipped with two sections of guide rails drives the guide rails to rotate at the same time, and a separate AC motor 38 can be driven to drive the driving shaft 36 at its output end to rotate, thereby driving the flip assembly 39 equipped with two sections of guide rails to rotate. The flipping assembly 39 rotates a certain section of the guide rail, thereby being able to flip and adjust the single section of the guide rail that needs to be welded separately, so that when two sections of the guide rail are installed and the welding surfaces of the two sections of the guide rail are not aligned, they can be adjusted separately, and the two sections of the guide rail can be flipped synchronously at the same time during the welding process, effectively avoiding the inefficient process of repeated disassembly and multiple repositioning of traditional flipping devices when installing the guide rails. At the same time, the dual-section synchronous flipping capability can complete the operation of multiple welding surfaces at one time while ensuring the stable alignment of the two sections of the guide rails, which not only greatly shortens the welding cycle, but also reduces the stress concentration and deformation risk during the welding process through synchronous flipping, thereby ensuring the welding quality and structural strength.

[0040] Embodiment 2:

[0041] On the basis of the first embodiment, the flip unit 3 further includes two groups of No. 1 locking brake assemblies 312 arranged on the frame body 2, each group of the No. 1 locking brake assemblies 312 includes a No. 2 transmission gear 3122 rotatably connected to the frame body 2, and the two sides of the No. 2 transmission gear 3122 are respectively meshed and connected with a rack 3123, and each of the racks 3123 is fixedly connected with a connecting slider 3121. It should be noted that the frame body 2 is provided with a groove for the connecting slider 3121 to slide, and each of the connecting sliders 3121 The lower end of each of the frames 2 is fixedly connected to a caliper 3124. It should be noted that the contact surface between the caliper 3124 and the brake pad 310 can be made of a material with a large friction coefficient to achieve a better locking effect, and the present scheme does not impose any restrictions on the material. The two calipers 3124 are symmetrically arranged to clamp the brake pad 310 to stop it from rotating, and an electric push rod 311 is provided on the frame 2. The output end of the electric push rod 311 is fixedly connected to one of the connecting sliders 3121 to drive it to slide along the groove located on the frame 2.

[0042] In the above example, a brake pad 310 is disposed on the outer wall of each rotating ring 393 , and each brake pad 310 is disposed between two calipers 3124 .

[0043] In this embodiment, the two drive shafts 36 are connected via a sleeve 35 . It should be noted that the drive shaft 36 is rotatably connected inside the sleeve 35 to connect the two sections of the drive shaft 36 together, and the sleeve 35 is fixedly connected to the driven gear 343 .

[0044] In this embodiment, each set of the No. 1 locking brake assembly 312 also includes a No. 1 connecting rod 3125 slidably connected to two symmetrically arranged calipers 3124, and the outer side of the No. 1 connecting rod 3125 is provided with a No. 1 spring 3126 arranged between the two calipers 3124. The No. 1 spring 3126 is used to push the two connecting sliders 3121 to reset, reduce the power output by the electric push rod 311, and facilitate the reset of the connecting slider 3121.

[0045] Specifically, the two electric push rods 311 can be driven simultaneously or separately, which is convenient for locking the two groups of flip assemblies 39 at the same time, and one group can be controlled to be locked separately. When the electric push rod 311 pushes one of the connecting sliders 3121 to slide in the groove located on the upper frame 2, it drives the rack 3123 connected to it to slide, and then the No. 2 transmission gear 3122 rotates to drive the other rack 3123 to rotate in the opposite direction, that is, drives the caliper 3124 to fit and clamp the brake pad 310, and the clamping force can be adjusted to limit the rotation speed of the brake pad 310, thereby ensuring the stability of the brake pad 310 during rotation and preventing welding dislocation or safety hazards caused by excessive rotation. At the same time, it can cooperate with the above-mentioned flip assembly 39 to allow one of the drive shafts 36 to rotate alone and lock it at the same time to ensure its stability.

[0046] Embodiment three:

[0047] On the basis of the second embodiment, the caliper 3124 is fixedly connected to a connecting frame 313, and a No. 2 brake lock assembly 315 is arranged on the connecting frame 313; the No. 2 brake lock assembly 315 includes a sleeve 3151 slidably connected to the drive shaft 36, the sleeve 3151 is connected to the caliper 3124 through the connecting frame 313, and a ring-shaped push block 3152 is fixedly connected to the sleeve 3151, and the opening size of the end of the ring-shaped push block 3152 close to the rubber block 3157 is larger than the opening size of the end away from the rubber block 3157, and the No. 2 brake lock assembly 315 also includes a circular plate 3155 fixedly connected to the frame body 2 through the fixing frame 314 to provide support, and the drive shaft 36 passes through the circular plate 3155 and can rotate with the circular plate 3155, and the circular plate 3155 is provided with grooves arranged in a ring array for installation Sliding shaft 3158, each of the grooves is fixedly connected to a sliding shaft 3158, and each of the sliding shafts 3158 is slidably connected to a sliding rod 3156, and each of the sliding rods 3156 is fixedly connected to a rubber block 3157 at one end away from the sliding shaft 3158, and the rubber block 3157 is an arc-shaped block, and is also made of a material with a large friction coefficient, which is used to lock the drive shaft 36, and multiple rubber blocks 3157 form a ring shape, which is sleeved on the outside of the drive shaft 36, and the rubber block 3157 can be set with a smooth arc surface at the contact point with the annular table-shaped push block 3152, thereby reducing the friction coefficient of the annular table-shaped push block 3152 in the process of pushing the rubber block 3157, and each of the sliding shafts 3158 is sleeved on the outside with a No. 2 spring 3159, and the No. 2 spring 3159 is set between the sliding rod 3156 and the circular plate 3155, so as to facilitate the resetting of the sliding rod 3156.

[0048] In this embodiment, a second connecting rod 3154 is fixedly connected to the circular plate 3155, and a ring frame 3153 is fixedly connected to the second connecting rod 3154 to play a role of limiting.

[0049] Specifically, when the caliper 3124 clamps the brake pad 310, it can drive the connecting frame 313 to move, and the connecting frame 313 drives the sliding sleeve 3151 to slide on the driving shaft 36. The sliding sleeve 3151 drives the annular table-shaped pushing block 3152 to push multiple rubber blocks 3157 to gather and clamp the driving shaft 36. In this process, the sliding rod 3156 slides along the sliding shaft 3158, and the No. 2 spring 3159 is stretched. When the locked state is released, it can be driven to reset under the action of the pulling force of the No. 2 spring 3159. At this point, when the caliper 3124 clamps the brake While the plate 310 ensures that the rotating ring 393 stops rotating, the drive shaft 36 can be locked by multiple rubber blocks 3157, providing double protection to prevent the welded guide rail from having an uneven distribution of the center of gravity, which causes the brake pad 310 to have a tendency to rotate. The locking of the brake pad 310 by the caliper 3124 can reduce the force on the inner tooth groove 394 and the No. 1 transmission gear 395 to prevent the No. 1 transmission gear 395 and the inner tooth groove 394 from being damaged. At the same time, the drive shaft 36 is locked by the rubber block 3157 to protect the AC motor 38 from being damaged.

[0050] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
