Description

Technical Field

[0001] This invention belongs to the field of winged rotary drum processing, specifically relating to a processing fixture and processing method for a winged rotary drum. Background Technology

[0002] Rotary drum with wing (specifically as follows) Figure 1 As shown, the blank materials for this type of cylinder are mostly cast aluminum alloy or aluminum alloy forgings. Their complex shape and poor rigidity at the wing plates make efficient and high-precision machining difficult. In particular, the winged rotary cylinder requires separate machining of the internal cavity and external wall, further increasing the complexity of its processing.

[0003] The main problem in the current processing is due to the complexity of the winged rotary cylinder itself. Because the rigidity of its wing plate is poor and there is no reliable support at the wing plate, it is difficult to clamp and position it effectively. This makes it easy for deformation to occur due to uncontrollable stress, which in turn greatly reduces the processing efficiency and makes it impossible to guarantee the processing accuracy and surface roughness requirements.

[0005] This invention proposes a machining fixture and method for a rotary cylindrical shell with wing. By setting up corresponding machining fixtures and matching them with corresponding machining process routes for the machining of the inner cavity and outer wall, the problem of difficult clamping and machining of this type of shell can be effectively solved. This reduces the cost of blanks while effectively ensuring the accuracy of the machining dimensions and surface roughness requirements of each feature, and improves the machining efficiency of the wing plate and the outer shape of the cylindrical shell.

[0042] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention may be combined with other embodiments without conflict.

[0043] A machining fixture for a winged rotary cylinder includes a turning fixture for machining the inner cavity of the winged rotary cylinder and a milling fixture for machining the outer wall of the winged rotary cylinder.

[0044] The turning fixture includes:

[0045] A pair of clamping rings 3 are provided at both ends of the wing plate 2 in the winged rotary drum. Each clamping ring 3 is provided with a through hole for the turning device to extend into the inner cavity of the winged rotary drum and a bolt hole 4 for positioning and connecting with the outer end of the wing plate 2 in the winged rotary drum.

[0046] Specifically, the clamping ring 3 is not limited to using, for example Figure 3 The annular structure shown can also be a regular polygonal structure or other structural forms, as long as it can be fixedly connected to the wing plate 2 and there is enough space for the turning tools to enter the inner cavity of the winged rotary cylinder. When machining with the above structure, the winged rotary cylinder to be machined must have connecting blocks 5 at both ends of its wing plate 2, and corresponding connecting bolt holes should be opened on the connecting blocks 5 for fixed connection. The connecting blocks 5 are not retained in the later stage and can be directly removed by milling in subsequent machining.

[0047] The milling fixture includes:

[0048] The upper core plate 6 and the lower core plate 7 respectively abut against the two ends of the inner cylinder 1 of the winged rotary cylinder;

[0049] The wing plate lower support device 9 is provided on the upper core plate 6 and the lower core plate 7, and the wing plate lower support device 9 abuts against the inner side of the wing plate 2 extending to the outside of the cylinder 1.

[0050] The wingplate side support device 15 abuts against the side of the wingplate 2;

[0051] A locking device is provided between the upper core plate 6 and the lower core plate 7 and applies opposing axial locking forces to both.

[0052] The upper core plate 6 and the lower core plate 7 are respectively engaged and connected to both ends of the inner cylinder 1 of the winged rotary drum. Specifically, corresponding stops can be set to ensure accurate connection and alignment. The upper core plate 6 and the lower core plate 7 are locked together by a locking device to apply opposing axial locking forces to ensure that the upper core plate 6, the winged rotary drum, and the lower core plate 7 form a fixed connection structure, which facilitates subsequent processing. At the same time, the lower support device 9 of the wing plate and the side support device 15 of the wing plate provide corresponding support forces for the wing plate 2 to ensure the reliability and accuracy when processing the wing plate 2.

[0053] In some embodiments, the wingplate side support device 15 is a detachable wingplate support baffle, and is abutted between adjacent wingplates 2. Figure 5As shown, there are 4 wing plates 2, which divide the whole into 4 processing surfaces. The front and back processing surfaces are not equipped with wing plate support baffles, while the left and right processing surfaces are equipped with wing plate support baffles. With the above-mentioned interval setting, the front and back can be processed first. During processing, there are no obstructing structural parts on the front and back, so the processing surfaces (including the outer end face of the cylinder 1 and the inner end faces of the two wing plates 2) can be processed quickly. When the left and right sides need to be processed, the wing plate support baffles can be removed and the positions changed.

[0054] Specifically, to ensure the structural stability and reliability of the support, the wing plate support baffle has an arc-shaped structure. The inner end face of the arc-shaped structure is adapted to and abuts against the outer end face of the cylinder 1, and the two ends of the arc-shaped structure abut against the adjacent wing plate 2.

[0055] Specifically, adhesive is provided at the junction of the wing plate side support device 15 with the cylinder 1 and the wing plate 2; adhesive is also provided at the junction of the wing plate lower support device 9 with the wing plate 2. The adhesive is used to further improve the support stability, and subsequent steps of removing the adhesive and polishing can be implemented.

[0056] In some embodiments, the underwing support device 9 includes:

[0057] Mounting block 8 is slidably installed along the axial direction of the winged rotary cylinder via longitudinal sliding groove 10;

[0058] A support plate is provided on the mounting block 8, and the outer end face of the support plate is in contact with the inner side of the wing plate 2 that extends to the outside of the cylinder 1.

[0059] The mounting block 8, installed on the upper core plate 6 and the lower core plate 7, will not affect the main structure of the winged rotary drum. The axial sliding setting allows the support plate to fit better with the wing plate 2, and also has a certain degree of adjustability, increasing the applicability of the equipment.

[0060] In some embodiments, the wingplate side support device 15 is a wingplate sliding baffle, which is laterally slidable on the mounting block 8 via a lateral sliding groove.

[0061] In this embodiment, another method is proposed to clamp and support the wing plate 2. Specifically, a wing plate sliding baffle is set on the mounting block 8 to clamp and support the two ends of the wing plate 2. This structural design is also relatively simple. The specific difference between this and the wing plate support baffle is that the clamping and supporting position of the wing plate 2 is different. Of course, the two structures mentioned above can be used at the same time to improve reliability, but it will be relatively cumbersome.

[0062] In some embodiments, it also includes:

[0063] The adjusting core disk 11 is located at the upper and / or lower end of the winged rotary cylinder and is engaged with the stop through a locking mechanism.

[0064] The main function of the adjusting core disk 11 is to adjust the axial position distance to achieve high-precision matching between various components. The adjusting core disk 11 can be directly fixed to the upper core disk 6 and the lower core disk 7 by bolt fastening. The adjusting core disk 11 and the winged rotary drum are connected by a stop-locking method, which will not affect the winged rotary drum body.

[0065] In some embodiments, the locking device includes:

[0066] The top cover 12 is engaged with the lower core disk 7;

[0067] The base 13 is fixedly connected to the upper core plate 6;

[0068] A screw 14 is installed inside the winged rotary cylinder. One end of the screw 14 extends to the outside of the top cover 12 and is provided with a fastening nut. The other end of the screw 14 extends to the outside of the base 13.

[0069] With the above setup, the entire device can be connected and fixed to the milling machine table to achieve spatial positioning of the entire device, thereby ensuring the effect of subsequent processing.

[0070] In some embodiments, the bolt hole 4 includes a threaded connection hole and a locating pin hole. The threaded connection hole is used for fixed connection, and the locating pin hole is used for quick positioning.

[0071] A method for manufacturing a rotary drum with winglets, comprising:

[0072] The two ends of the wing plate 2 of the winged rotary cylinder are provided with integrally cast connecting blocks 5;

[0073] During the machining of the inner cavity of the winged rotary cylinder, a pair of clamping rings 3 are fixedly connected to the connecting block 5 on the wing plate 2 through the bolt hole 4 on the clamping rings 3, so that the pair of clamping rings 3 are installed at both ends of the wing plate 2 in the winged rotary cylinder to form a connection support and fixation. Then, the turning device is inserted into the inner cavity of the winged rotary cylinder through the through hole on the clamping ring 3 to complete the machining of the inner cavity of the winged rotary cylinder.

[0074] During the machining of the outer wall of the winged rotary cylinder, the upper core plate 6 and the lower core plate 7 are abutted against the two ends of the inner cylinder 1 of the winged rotary cylinder, and the position of the wing plate lower support device 9 installed on the upper core plate 6 and the lower core plate 7 is adjusted so that the wing plate lower support device 9 and the inner side of the wing plate 2 extending to the outside of the cylinder 1 form an abutment state; the upper core plate 6 and the lower core plate 7 are clamped by the locking device, specifically by rotating the fastening nut to squeeze the top cover 12 so that the various structures are tightly connected and fixed; then any machining surface formed between the inner ends of the two wing plates 2 is selected, the machining surface includes the outer end face of the cylinder 1 between the inner ends of the two wing plates 2 and the inner end face of the two wing plates 2; wing plate side support devices 15 are set at the outer ends of the wing plates 2 on both sides of the machining surface for support; the machining surface is milled by the milling device, and the corresponding connecting block 5 is milled and removed, and so on until the milling of all machining surfaces and the milling of connecting blocks 5 are completed, and all wing plate side support devices 15 are removed to complete the machining of the outer wall of the winged rotary cylinder.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
