Description

Technical Field

[0001] The invention relates to the field of processing and manufacturing of sleeve flange welded parts, and in particular to a processing tool for sleeve flange welded parts. Background Art

[0002] Sleeve flange welded parts are used to assemble precision parts such as bearings and oil seals, and have high requirements on the diameter and coaxiality of the mounting holes. Therefore, it is necessary to design and process tooling to clamp the sleeve flange welded parts to be processed and complete all processing content on the tooling at one time.

[0003] The prior art tooling for processing sleeve flange welded parts fixes the sleeve flange welded parts through two fixing seats. However, due to the inevitable dimensional error between the fixing seats and the flange ends at both ends of the sleeve flange welded parts, the fixing seats and the flange ends cannot be in full contact, resulting in no axial support during the processing of the flange ends. During cutting, due to the axial force and vibration during the processing, the dimensional consistency is poor, which has a serious impact on the processing quality of the parts to be processed.

[0004] Therefore, how to provide a solution to solve the above-mentioned defects is still a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] For convenience, the relevant terms in this embodiment are defined as follows:

[0030] In this article, the side walls opposite to the two flange ends in the sleeve flange weldment 01 are inner side walls; the direction close to the two fixing parts 1 is "inside", and the opposite direction is "outside".

[0031] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of the casing flange welded parts to be processed.

[0032] The sleeve flange weldment processing tooling of the present invention is used to clamp and position the sleeve flange weldment 01 to be processed. The sleeve flange weldment 01 includes a sleeve 011 and a flange end 012 located at one end of the sleeve 011 and another flange end 013. The shapes and structures of the two flange ends are not consistent. The flange end has a mounting hole near the outer edge. In this embodiment, the mounting hole is used as the positioning hole 012a.

[0033] After understanding the structure of the sleeve flange welded part 01, the specific structure of the sleeve flange welded part processing tooling of the present invention will be described in detail.

[0034] Please refer to Figures 2 to 4 , Figure 2 It is a structural schematic diagram of a specific embodiment of a processing tool for sleeve flange welding parts of the present invention; Figure 3 for Figure 2 A schematic diagram of the structure of the casing flange welding parts processing tooling from another angle; Figure 4 for Figure 2 Schematic diagram of the split structure of the elastic clamping part in the processing tooling of the sleeve flange welding parts.

[0035] The present invention provides a sleeve flange weldment processing tool, comprising two fixing parts 1, with a predetermined distance between the two fixing parts 1, and the outer side walls of the fixing parts 1 are provided with supporting parts, wherein the distance between the outer end surface of at least one supporting part and the outer side wall of the corresponding fixing part 1 is adjustable, and when the sleeve flange weldment 01 to be processed is installed on the sleeve flange weldment processing tool, the inner side walls of the flange ends at both ends of the sleeve flange weldment 01 can respectively abut against the outer side walls of the two supporting parts.

[0036] The processing tooling of the sleeve flange weldment of the present invention is provided with a support portion on the outer side wall of the fixing portion 1, and the outer end face of at least one support portion 3 is at an adjustable distance from the outer side wall of the corresponding fixing portion 1. When the sleeve flange weldment 01 to be processed is installed on the processing tooling, first, it is ensured that the inner side wall of one flange end 012 of the sleeve flange weldment 01 is abutted against a support portion 2, and then the other support portion 3 is adjusted to ensure that the outer end portion of the support portion 3 is abutted against the inner side wall of the other flange end 013. When processing the sleeve flange weldment 01, such as cutting and boring the outer side wall of the flange end, the two support portions can provide axial support force for the sleeve flange weldment 01. On the one hand, the flexibility of the tooling is improved to meet the processing requirements of sleeve flange weldments 01 of different sizes; on the other hand, the dimensional consistency of the sleeve flange weldment 01 to be processed is ensured during processing, and the axial position of the sleeve flange weldment 01 to be processed is avoided from being offset during processing, thereby ensuring the processing quality of the sleeve flange weldment 01 to be processed.

[0037] In the present invention, one of the supporting parts 2 is fixedly connected to the corresponding fixing part 1, and the specific connection method is not limited, for example, it can be fixed by welding, threaded connection, etc.; specifically in the embodiment of the accompanying drawings, a connecting hole that penetrates inside and outside is set at a predetermined position of the fixing part 1, and the supporting part 2 includes a large diameter section and a small diameter section. The small diameter section of the supporting part 2 is inserted into the connecting hole from outside to inside, and the end face of the large diameter section is in contact with the outer side wall of the fixing part 1. The side wall of the small diameter section is provided with a thread, and the fixing nut of the small diameter section is set to achieve the fixing of the supporting part 2 and the fixing part 1.

[0038] Furthermore, the distance between the outer end face of another supporting portion 3 and the outer side wall of the corresponding fixing portion 1 is adjustable. Specifically, in the implementation of this embodiment, the corresponding fixing portion 1 is provided with a mounting hole that penetrates inside and outside, and the supporting portion 3 is inserted into the mounting hole from inside to outside, and can move along the axial direction of the mounting hole, so that the outer end face of the supporting portion 3 passes through the fixing portion 1 by a predetermined distance and abuts against the inner end face of the flange end. Of course, in practical applications, the supporting portion 3 can also adopt other implementations to achieve the above-mentioned adjustment function, such as fixing a screw extending in the inner and outer directions on the outer side wall of the fixing portion 1, and a nut is fitted on the screw through a knob, so that the outer end face of the nut can abut against the inner end face of the flange end.

[0039] Please refer to Figure 2 and Figure 4 The inner side wall of the fixing part 1 is also provided with a mounting sleeve 4 connected with the mounting hole, and the side wall of the mounting sleeve 4 is provided with a through-limiting hole 42. The support part 3 is inserted into the mounting sleeve 4, and a clamping surface 31 is provided at a predetermined position of the side wall of the support part 3. It also includes a clamping bolt 5, which can be screwed into or out of the limiting hole 42 to clamp or loosen the clamping surface 31. Specifically, when it is necessary to adjust the position of the support part 3, the clamping bolt 5 can be screwed out along the limiting hole 42 to loosen the clamping surface 31 of the support part 3; when the outer end of the support part 3 abuts against the inner side wall of the flange end 013 of the sleeve flange weldment 01, the clamping bolt 5 is screwed into the limiting hole 42 and the clamping surface 31 of the support part 3 is clamped to fix the support part 3 at the current position.

[0040] In this embodiment, the support part 3 is fixed by providing a clamping bolt 5 to clamp the clamping surface 31 of the support part 3. In practical applications, the support part 3 can also be fixed by other methods, such as not providing the mounting sleeve 4, but providing an internal thread on the side wall of the mounting hole for inserting the support part 3, and providing a matching external thread on the side wall of the support part 3, and adjusting the distance that the outer end surface of the support part 3 passes through the fixing part 1 by rotating the support part 3 inwardly or outwardly.

[0041] Furthermore, in the present embodiment, the inner end side wall of the mounting sleeve 4 is relatively provided with two limit grooves 41 which are opened at the inner ends and extend outward, and the inner end side wall of the support portion 3 is relatively provided with two limit rods 32, and also includes an elastic component. The support portion 3 can rotate inside the mounting sleeve 4 so that the limit rods 32 are against the inner end surface of the mounting sleeve 4. At this time, the elastic component is in an energy storage state; or, the limit rods 32 are clamped in the limit grooves 41, and the support portion 3 moves outward along the axial direction of the mounting sleeve 4, and the outer end surface of the support portion 3 passes through the fixing portion 1 by a predetermined distance. With this arrangement, when the sleeve flange welded part 01 to be processed needs to be installed, or the sleeve flange welded part 01 that has been processed needs to be disassembled, the support part 3 can be pulled inward, and the limiting rod 32 of the support part 3 can be abutted against the inner end face of the installation sleeve 4, so that the outer end face of the support part 3 is retracted to the inner side of the fixing part 1 to avoid interference with the flange end of the sleeve flange welded part 01; when the installation is completed, the support part 3 can move outward by itself under the action of the restoring force of the elastic component to abut against the flange end 013 of the sleeve flange welded part 01, the operation is simple, and the practicability of the sleeve flange welded part processing tooling of the present invention is effectively improved.

[0042] Of course, there is no limitation on the number of limiting grooves 41 provided on the mounting sleeve 4 and the number of limiting rods 32 provided on the supporting portion 3 . The mounting sleeve 4 can be provided with at least one limiting groove 41 , and the supporting portion 3 can be provided with at least one limiting rod 32 .

[0043] In addition, the elastic component can be a spring, a tension rope, an elastic ball, or other elastic elements of various styles, as long as they can achieve the above-mentioned end effect. In the embodiment of the accompanying drawings, the elastic component is a spring 6, which is mounted on the support portion 3. One end of the spring 6 can interact with the support portion 3, and the other end can interact with the mounting sleeve 4. The specific interaction position can be provided with a boss, a shoulder, or other structures to provide a support position and / or a connection position for the spring 6.

[0044] During the process of the support portion 3 contracting inward, the elastic component can gradually store energy, so that the subsequent support portion 3 can move outward by itself under the restoring force of the elastic component to counteract the flange end 013 of the sleeve flange weldment 01. This energy storage can be compression energy storage or tension energy storage, which is related to the installation location, type, etc. of the elastic component and is not limited here. It should be noted that when the elastic component adopts the tension energy storage scheme, the two ends of the elastic component need to be fixedly connected with the corresponding mounting sleeve 4 and support portion 3 so that the elastic component can generate a tensile force. The specific fixing method can be welding, clamping, bonding, etc., which is not limited here. Specifically, in the embodiment of the accompanying drawings, the energy storage process of the elastic component is a compression process. At this time, its two ends do not need to be fixed, and the structure can be relatively simple.

[0045] In this embodiment, the axial direction of the limiting rod 32 is perpendicular to the normal direction of the clamping surface 31, and the limiting groove 41 and the clamping bolt 5 are correspondingly arranged on the mutually perpendicular side walls of the mounting sleeve 4. When the limiting rod 32 is clamped in the limiting groove 41, the clamping surface 31 is just opposite to the clamping bolt 5. In practical applications, the clamping bolt 5 can also be arranged on the same side wall of the mounting sleeve 4 as one of the limiting grooves 41. In this case, the axial direction of the limiting rod 32 is perpendicular to the clamping surface 31 arranged on the side wall of the support portion 3.

[0046] Please continue to refer to Figure 2 In the present invention, the fixing part 1 includes a fixing seat 11 and a fixing pressure plate 12 which are arranged relatively to each other. The fixing seat 11 and the fixing pressure plate 12 can be relatively close to or far away from each other. When the fixing seat 11 and the fixing pressure plate 12 are relatively close to each other, they can enclose and form a mounting groove. When the sleeve flange weldment 01 is installed on the fixing part 1, the sleeve 011 of the sleeve flange weldment 01 is inserted into the mounting groove to ensure the installation stability of the sleeve flange weldment 01.

[0047] Specifically, in this embodiment, a connecting bolt for connecting the fixed pressure plate 12, namely a first bolt 13 and a second bolt 14, is respectively provided at both ends of the fixing seat 11. The first bolt 13 and the second bolt 14 both include a head and a screw portion. The heads of the first bolt 13 and the second bolt 14 are hinged to the fixing seat 11. A connecting hole is provided at one end of the fixed pressure plate 12, and the screw portion of the first bolt 13 is fitted through the connecting hole. The screw portion of the first bolt 13 is also fitted with two connecting nuts 15, and the two connecting nuts 15 are located on both sides of the fixed pressure plate 12, and are used to fix the fixed pressure plate 12 to the predetermined position of the screw portion. The first bolt 13 can drive the fixed pressure plate 12 to rotate around the hinge with the fixed seat 11, so that the other end of the fixed pressure plate 12 is close to or away from the fixed seat 11; the other end of the fixed pressure plate 12 is provided with a connecting groove 121 matching the second bolt 14. When the fixed pressure plate 12 is close to the fixed seat 11, that is, supported on the top of the fixed seat 11, the second bolt 14 can rotate around the hinge with the fixed seat 11 and be inserted into the connecting groove 121 of the fixed pressure plate 12. A fixing nut 16 is also mounted on the end of the second bolt 14 for locking the relative position of the fixed pressure plate 12 and the fixed seat 11.

[0048] During actual use, first support the sleeve flange weldment 01 to be processed on the fixed seat 11, rotate the fixed pressure plate 12, and support the fixed pressure plate 12 on the top of the fixed seat 11. At this time, the sleeve 011 of the sleeve flange weldment 01 is clamped in the installation groove formed by the fixed pressure plate 12 and the fixed seat 11; then rotate the second bolt 14 around the hinge, insert the second bolt 14 into the connecting groove 121 of the fixed pressure plate 12, twist the fixing nut 16 of the second bolt 14, and lock the fixed pressure plate 12 and the fixed seat 11.

[0049] If the size of the part to be processed is large or small, and it is impossible to lock the fixed pressure plate 12 and the fixed seat 11 or lock the part to be processed, the two connecting nuts 15 of the first bolt 13 can be turned to adjust the fixed position of the fixed pressure plate 12 relative to the first bolt 13 to adapt to the clamping requirements of the sleeve flange weldment 01 of parts to be processed of different sizes, and ensure that when the sleeve flange weldment 01 is installed on the processing tooling, the fixed pressure plate 12 can just lock the position of the sleeve 011 to prevent the position of the sleeve flange weldment 01 from shifting during the processing. On the one hand, the positioning accuracy of the sleeve flange weldment processing tooling of the present invention is improved; on the other hand, the processing requirements of sleeve flange weldments 01 of different sizes are met, and the scope of application of the sleeve flange weldment processing tooling of the present invention is improved.

[0050] In addition, in the present embodiment, one end of the fixed pressure plate 12 is hinged to the fixed seat 11 by the first bolt 13, and can rotate around the hinge so that the other end of the fixed pressure plate 12 is close to or away from the fixed seat 11; in practical applications, a connecting bolt extending vertically upward can also be fixed at both ends of the fixed seat 11, and two connecting bolts are always installed at both ends of the fixed pressure plate 12. When the sleeve flange welded part 01 needs to be installed, the fixed pressure plate 12 can be lifted in the vertical direction so that there is enough space between the fixed pressure plate 12 and the fixed seat 11, and the sleeve flange welded part 01 to be processed is installed between the fixed pressure plate 12 and the fixed seat 11, and then the fixed pressure plate 12 is lowered along the connecting bolt so that the fixed pressure plate 12 is against the sleeve 011 of the sleeve flange welded part 01. At this time, the fixed pressure plate 12 is locked by the connecting nut of the connecting bolt to ensure the installation accuracy of the sleeve flange welded part 01 and avoid the sleeve flange welded part 01 from being offset during the processing.

[0051] Please continue to refer to Figure 2 A positioning hole penetrating inside and outside is also provided at a predetermined position of any fixing part 1, and also includes an angular positioning pin 7 inserted into the positioning hole from the inside to the outside. The angular positioning pin 7 can move along the axial direction of the mounting hole and pass through the fixing part 1 by a predetermined distance. When the sleeve flange welded part 01 to be processed is installed on the processing tooling, the angular positioning pin 7 can be inserted into the positioning hole 012a of the flange end 012 and contact the inner end peripheral wall of the positioning hole 012a.

[0052] By providing an angular positioning pin 7, which cooperates with any positioning hole 012a of the flange end, the angular positioning of the sleeve flange weldment 01 is achieved, the sleeve flange weldment 01 is prevented from rotating during processing, and the clamping accuracy of the sleeve flange weldment 01 of the present invention is improved. In addition, in practical applications, it is necessary to limit the length of the angular positioning pin 7 inserted into the positioning hole 012a of the flange end, that is, it only needs to contact the inner end peripheral wall of the positioning hole 012a, so as to avoid the angular positioning pin 7 interfering with the processing process when cutting the outer side wall of the flange end 012.

[0053] In addition, in this embodiment, an anti-error block 8 is also provided on the outer wall of one of the fixed seats 11. The shape of the anti-error block 8 is roughly U-shaped and matches the shape of one of the flange ends 012 in the sleeve flange welded part 01, and the anti-error block 8 is detachably connected to the fixed seat 11.

[0054] Since the shapes of the flange ends at both ends of the sleeve flange weldment 01 to be processed are inconsistent, an anti-error block 8 is provided on the outer wall of one of the fixing seats 11. When installing the parts to be processed, the flange end 012 matching the shape of the anti-error block 8 can be installed on the same side to avoid installing the sleeve flange weldment 01 upside down.

[0055] In addition, the anti-error block 8 is detachably connected to the fixing seat 11. When the size and shape of the sleeve flange welded part 01 to be processed changes, the anti-error block 8 matching the shape and size of the flange end can be replaced, thereby improving the flexibility and applicability of the sleeve flange welded part processing tooling of the present invention.

[0056] In this embodiment, the anti-error block 8 is installed on the outer wall of one of the fixed seats 11. In actual applications, the anti-error block 8 can also be installed on the other fixed seat 11, or the anti-error blocks can be installed on the outer walls of both fixed seats 11. At this time, the anti-error block 8 on one side matches the flange end 012 at one end of the sleeve flange welded part 01 to be processed, and the anti-error block on the other side matches the flange end 013 at the other end of the part to be processed.

[0057] For further information, please refer to Figure 2 The sleeve flange welding parts processing tooling of the present invention also includes a base 9, which is provided with a slide rail 101. The bottoms of the two fixed seats 11 are provided with sliders 102 matching the slide rails 101. The fixed seats 11 are installed on the slide rails 101 through the sliders 102 and can move along the slide rails 101 so that the two fixed seats 11 maintain a predetermined distance.

[0058] The sleeve flange weldment processing tooling of the present invention sets a slide rail and slider transmission unit so that the two fixing seats 11 can be maintained at a required distance, thereby meeting the clamping requirements of sleeve flange weldments 01 with different sleeve 011 lengths. Specifically, the sleeve flange weldment processing tooling of the present invention can clamp the sleeve flange weldment 01 in a size range that meets the distance between the inner end faces of the two flange ends of 280mm to 700mm, thereby improving the application scope of the sleeve flange weldment processing tooling of the present invention.

[0059] In this embodiment, the base 9 is provided with two coaxial slide rails 101, and one fixed seat 11 is installed on one slide rail 101. In actual application, only one slide rail 101 extending along the length direction of the base 9 is provided, and two fixed seats 11 are installed on one slide rail 101 at the same time, which is also a feasible solution.

[0060] In this embodiment, the slider 102 and the slide rail 101 are respectively arranged in the middle of the bottom wall of the fixed seat 11 and the middle of the base 9. A guide block is also provided at both ends of the bottom wall of the fixed seat 11. The base 9 is also provided with a guide groove 91 parallel to the slide rail 101 on both sides of the slide rail 101. The guide block is installed in the guide groove 91 on the same side and can move axially along the guide groove 91 to play a guiding role, thereby ensuring the stability of the fixed seat 11 during the movement, improving the clamping accuracy of the sleeve flange weldment processing tooling of the present invention, and thereby improving the processing accuracy of the sleeve flange weldment 01 to be processed.

[0061] Of course, in practical applications, the positions of the guide components (guide groove 91 and guide block) and the sliding components (slider 102 and slide rail 101) are not strictly limited, as long as they can play the role of guidance and transmission.

[0062] In addition, both ends of the fixing seat 11 are provided with a threaded positioning hole 111 on both the inner and outer sides, respectively, and also include positioning bolts inserted into the threaded positioning hole 111, the positioning bolts can be screwed into or out of the threaded positioning hole 111, and can be abutted against the base 9 to fix the fixing seat 11 at a predetermined position of the base 9. This arrangement enables the fixing seat 11 to be stabilized at a predetermined position during the processing, thereby ensuring the clamping accuracy of the sleeve flange welded part 01 to be processed.

[0063] In this embodiment, the position of the threaded positioning hole 111 corresponds to the position of the guide groove 91, and the positioning bolt abuts against the bottom wall of the guide groove 91 to fix the relative position of the base 9 and the fixing seat 11. In actual applications, the position and number of the threaded positioning holes 111 are not limited, as long as they can play the role of fixing the relative position of the base 9 and the fixing seat 11.

[0064] In addition, four lifting parts 103 are provided around the top of the base 9. The lifting parts 103 can specifically be lifting components in the form of lifting rings, etc., for lifting the base 9. The lifting parts 103 can be installed on the base 9 by various means such as welding and threaded connection.

[0065] The working process of the casing flange weldment processing tool of the present invention when installing the casing flange weldment 01 is as follows:

[0066] First, the distance between the two fixing seats 11 is adjusted according to the size of the sleeve flange welded part 01 to be processed. When the two fixing seats 11 are at a predetermined distance, the fixing seats 11 are locked on the base 9 by positioning bolts.

[0067] Secondly, support the sleeve flange weldment 01 to be processed on the top of the fixed seat 11. Specifically, first support one end of the sleeve flange weldment 01 on the top of one of the fixed seats 11, and make the inner wall of the flange end 012 on this side abut against the support part 2 on the same side, then support the flange end 013 of the sleeve flange weldment 01 on the top of the other fixed seat 11, turn the support part 3 on this side, and adjust the support part 3 to move outward so that the outer end of the support part 3 abuts against the inner wall of the flange end 013 on this side; at the same time, insert the angular positioning pin 7 into the positioning hole 012a of the flange end 012 to limit the rotation of the sleeve flange weldment 01.

[0068] Then, rotate the two fixed pressure plates 12 around the hinge so that they are supported on the top of the fixed seat 11, and lock the position of the fixed pressure plate 12 and the fixed seat 11 through the second bolt 14 and the fixing nut 16 that is fitted on the second bolt 14; at this time, if the size of the sleeve 011 of the sleeve flange weldment 01 is too large or too small, and the fixed pressure plate 12 and the fixed seat 11 cannot be locked or tightened, the fixed pressure plate 12 can be adjusted to be fixed to the position of the first bolt 13.

[0069] Finally, the sleeve flange welded part 01 is processed. After the processed sleeve flange welded part 01 is disassembled, the above steps are repeated to process other sleeve flange welded parts 01 to be processed.

[0070] The above is a detailed introduction to a sleeve flange welding tooling provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, the present invention can also be improved and modified without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
