Description

Technical Field

[0001] The invention relates to the technical field of ring processing, and in particular to a ring side wall hole processing device. Background Art

[0002] When processing thin-walled rings with large diameters, a universal rocker drill is usually used for processing. However, due to the arm length and rotation angle of the universal rocker drill, the working range of the universal rocker drill is often limited. When the diameter of the ring to be processed is very large (such as a diameter of more than 3 meters, etc.), the workbench needs to be moved or rotated to meet the processing requirements.

[0003] In order to solve the above problems, the prior art generally adopts the form of setting a workbench. The existing workbench structures currently include a workbench structure using three or four groups of support piers to support the workpiece, a single diameter support workbench structure, and a concentric variable diameter workbench structure. However, the existing workbench still has the following problems, among which:

[0004] The workbench structure that uses three or four groups of support piers to support the workpiece is difficult to maintain its flatness after long-term use due to the wear problem of the workbench. In addition, it requires a large amount of labor and the cooperation of the crane to meet the position adjustment of the ring, so it also has the disadvantages of long processing cycle and low work efficiency.

[0005] Single-diameter workbench, due to the limited arm length and rotation angle of the rocker universal drill, can only meet the processing of rings within a single diameter range. When processing different rings with different diameters, multiple workbenches need to be set up, increasing cost investment;

[0006] Although the concentric variable diameter workbench can meet the processing needs of rings with different diameters, it is necessary to repeatedly move the machine tool during the processing of outer diameter holes and inner diameter holes at different positions, making it difficult to ensure that the radial hole points to the axis of the ring. Summary of the invention

[0011] Optionally, a sliding groove for installing a positioning roller is further provided on the mounting structure, and the ring is clamped or loosened by adjusting the relative position of the positioning roller in the sliding groove.

[0029] The drilling structure 2 is preferably configured as a rocker universal drilling machine, and the rocker universal drilling machine is preferably provided with two pieces arranged oppositely, and the two rocker universal drilling machines are respectively arranged on the inner and outer sides of the ring 3; when processing the side wall hole on the outer wall of the ring 3, the rocker universal drilling machine located on the inner side of the ring 3 limits and fixes the ring 3 to prevent the rocker universal drilling machine located on the outer side of the ring 3 from causing the ring 3 to deviate when processing the side wall hole; when processing the side wall hole on the inner wall of the ring 3, the rocker universal drilling machine located on the outer side of the ring 3 limits and fixes the ring 3 to prevent the rocker universal drilling machine located on the inner side of the ring 3 from causing the ring 3 to deviate when processing the side wall hole. It is preferred here that: the drilling structure 2 is preferably arranged oppositely to the second slide assembly 1.2.

[0030] Optionally, in order to make the ring side wall hole processing device adaptable to the side wall hole processing of rings 3 with different diameters, the structures of the first slide assembly 1.1, the second slide assembly 1.2 and the third slide assembly 1.3 are all consistent; taking the first slide assembly 1.1 as an example, it includes a slide body 1.1.1, a ball screw 1.1.2 arranged on the slide body 1.1.1, a screw nut 1.1.3 cooperating with the ball screw 1.1.2, and a first driving member connected to the screw in the ball screw 1.1.2; the clamping assembly 1.4 is interconnected with the screw nut 1.1.3 in the ball screw 1.1.2, so as to drive the clamping assembly 1.4 to move through the drive of the ball screw 1.1.2, so as to achieve clamping of rings 3 with different diameters by adjusting the relative positions of the clamping assemblies 1.4 located on the first slide assembly 1.1, the second slide assembly 1.2 and the third slide assembly 1.3.

[0031] Optionally, in order to achieve precise clamping of rings 3 of different diameters, scale lines 1.1.5 are provided on the outer side surface of the slide along the displacement direction of the screw nut 1.1.3 in the ball screw 1.1.2, and a pointer 1.1.4 is provided on the screw nut 1.1.3 of the ball screw 1.1.2. The pointer 1.1.4 is displaced along the scale line 1.1.5 by the ball screw 1.1.2, so that the position of the screw nut 1.1.3 on the slide can be precisely adjusted according to the clamping requirements of rings 3 of different diameters.

[0032] Optionally, in order to realize the processing requirements of the side wall holes at different positions of the ring 3, a single clamping assembly 1.4 includes a connecting block 1.4.1, a first fixed block 1.4.2, a second fixed block 1.4.3, a supporting roller 1.4.4, a positioning roller 1.4.5 and a second driving member; the connecting block 1.4.1 is fixedly connected to the screw nut 1.1.3 of the ball screw 1.1.2, and is displaced by the drive of the ball screw 1.1.2; the first fixed block 1.4.2 and the second fixed block 1.4.3 are spaced apart from each other, and the two ends of the supporting roller 1.4.4 are respectively connected to the first fixed block 1.4.2 and the second fixed block 1.4.3 through bearings The two fixed blocks 1.4.3 are rotationally connected, and one end of the supporting roller 1.4.4 is also connected to a second driving member, and is driven to rotate by the second driving member; one end of the positioning roller 1.4.5 is interconnected with the first fixed block 1.4.2, and the central axis of the positioning roller 1.4.5 and the central axis of the supporting roller 1.4.4 are arranged perpendicular to each other; the lower end surface of the ring 3 is placed on the supporting roller 1.4.4, and the ring 3 is driven to rotate by the second driving member, and the outer wall of the ring 3 is in rolling contact with the positioning roller 1.4.5, thereby realizing both the positioning of the outer wall of the ring 3 and the flexible rotation of the ring 3.

[0033] Optionally, in order to facilitate the precise positioning of the positioning roller 1.4.5 on the outer wall of the ring 3, a sliding groove A for installing the positioning roller 1.4.5 is also provided on the first fixed block 1.4.2 for installing the positioning roller 1.4.5. Before the ring 3 is positioned and installed, the positioning roller 1.4.5 is in an initial state (that is, the positioning roller 1.4.5 is arranged on the end of the sliding groove A away from the supporting roller 1.4.4, so that a gap is provided between the positioning roller 1.4.5 and the supporting roller 1.4.4, so that the ring 3 can be easily installed between the three groups of clamping assemblies 1.4); when the ring 3 is placed on the supporting roller 1.4.4, the positioning roller 1.4.5 is adjusted to move in a direction close to the supporting roller 1.4.4, so that the positioning roller 1.4.5 and the ring 3 are in contact with each other, so as to achieve precise positioning of the ring 3. It is preferred here: in order to reduce the adjustment of the positioning roller 1.4.5 and ensure the precise positioning of the ring 3, among the three groups of clamping assemblies 1.4, only one group of the clamping assemblies 1.4 may be provided with a sliding groove A on the first fixed block 1.4.2, so that the positioning roller 1.4.5 of one of the three groups of clamping assemblies 1.4 is set to an adjustable structure while the positioning rollers 1.4.5 of the other two groups of clamping assemblies 1.4 are set to a fixed structure.

[0034] Optionally, in order to reduce the friction between the support roller 1.4.4 and the ring 3, the outer surface of the support roller 1.4.4 is preferably set to a conical structure, so that the support roller 1.4.4 and the ring 3 are connected in a pure rolling contact manner, which can reduce the possibility of the support roller 1.4.4 scratching the surface of the ring 3 and extend the service life of the support roller 1.4.4. Preferably, the end of the support roller 1.4.4 with a larger outer diameter is arranged close to the positioning roller 1.4.5.

[0035] In addition to the above structure, in order to ensure that the end faces of the first slide assembly 1.1, the second slide assembly 1.2 and the third slide assembly 1.3 for installing the ring 3 are on the same horizontal plane, at least one height adjustment assembly 1.5 is also provided on the first slide assembly 1.1, the second slide assembly 1.2 and the third slide assembly 1.3.

The height adjustment of the first slide assembly 1.1, the second slide assembly 1.2 and the third slide assembly 1.3 is achieved by adjusting the relative distance between the locking nut 1.5.3 and the base 1.5.1.

[0036] The process of using the above-mentioned ring side wall hole processing device to process the outer side wall hole of the ring is as follows:

[0037] Step 1: Install the ring side wall hole processing device described above, and adjust the relative positions of the three groups of clamping components according to the diameter of the ring to be processed;

[0038] Step 2: transport the ring to the three groups of support rollers, and ensure that the outer wall of the ring is in rolling contact with two groups of positioning rollers of the fixed structure; adjust the positioning roller of the adjustable structure toward the direction of the ring so that it is in rolling contact with the outer wall of the ring, and complete the loading of the ring;

[0039] Step 3, start the second driving member, so that the ring is driven by the supporting roller to rotate the side wall hole processing position of the ring and place it between the two rocker arm universal drilling machines. When processing the side wall hole on the inner wall of the ring, drive the rocker arm universal drilling machine placed at the outer wall of the ring to contact with the outer wall of the ring to limit the ring, and then drive the rocker arm universal drilling machine placed at the inner wall of the ring to achieve drilling operation; when processing the side wall hole on the outer wall of the ring, drive the rocker arm universal drilling machine placed at the inner wall of the ring to contact with the inner wall of the ring to limit the ring, and then drive the rocker arm universal drilling machine placed at the outer wall of the ring to achieve drilling operation;

[0040] Step 4: Repeat step 3 until all the side wall holes required to be processed on the ring are processed;

[0041] Step 6: The positioning roller of the adjustable structure is adjusted in a direction away from the ring member so that the positioning roller is separated from the ring member; and then the ring member is transported to a designated position to realize unloading of the ring member.
