Description

Technical Field

[0001] This utility model relates to the field of flange processing, specifically to flange processing fixtures. Background Technology

[0002] A flange, also known as a flange, is a general term that usually refers to a metal disc with multiple sets of openings around its perimeter for fixing. These openings are used to connect other things. Due to its versatility, it is widely used in mechanical devices. When processing flanges, fixing devices are needed to fix the position of the flanges.

[0003] Chinese Patent No. CN202320552727.5 discloses a flange processing fixture, including a column. A clamping device is provided on one side of the column, and a limiting device is provided on the top of the column. The clamping device includes two first rectangular slots symmetrically opened on the column. A first circular hole is opened on one side of the column. A second circular hole is opened on the inner wall of the first rectangular slot. A bidirectional threaded rod is provided inside the first circular hole. The thread shape of the bidirectional threaded rod is arranged in opposite symmetrical arrangement. The bidirectional threaded rod is disposed inside the two first rectangular slots and the second circular hole. One end of the bidirectional threaded rod is rotatably connected to the inner wall of the other first rectangular slot. Two threaded hole rods are symmetrically threaded on the surface of the bidirectional threaded rod. The surfaces of the two threaded hole rods are slidably connected to the inner walls of the two first rectangular slots respectively. An arc-shaped clamping plate is fixedly connected to one side of each of the two threaded hole rods.

[0004] As can be seen from the above, by setting up a clamping device, the bidirectional threaded rod can drive the two threaded hole rods to move in opposite directions, thereby allowing the two arc-shaped clamping plates to press and fix the flange, reducing the situation where the flange rotates during processing and affecting the processing, and improving the stability of the flange processing process. However, this case still has the following shortcomings: when performing flange fixing work, the existing technology does not allow the flange to move during fixing, which leads to disassembly and fixing again when processing the other side of the flange, which is more complicated in operation and thus reduces the efficiency of flange processing.

[0005] Therefore, a flange machining fixture is proposed to address the above issues. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and address the issue of fixed flanges that cannot move, this utility model proposes a flange processing fixture.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The flange processing fixture of this utility model includes a base and a movable fixing device; the movable fixing device is equipped with a servo motor, and a first sprocket is fixedly installed at the output end of the servo motor. A chain is driven to one side of the first sprocket, and a second sprocket is driven to the other side of the chain. A rotating block is fixedly installed on one side of the second sprocket, and a connecting seat is movably installed through one side of the rotating block.

[0008] Preferably, the base is equipped with a fixing frame, and a working platform is fixedly installed on the top of the fixing frame.

[0009] Preferably, a machining flange is movably connected to one side of the rotating block, a limit block is movably connected to the other end of the machining flange, a bearing is movably installed on the other side of the limit block, and one side of the bearing is fixedly installed to the output end of the first hydraulic cylinder.

[0010] Preferably, a mounting base is fixedly installed on the top of the working platform, a connecting base is fixedly installed on the top of the working platform, a support base is fixedly installed on the top of the working platform, and a first hydraulic cylinder is fixedly installed through one side of the support base.

[0011] Preferably, a connecting plate is fixedly installed on the top of the working platform, and a second hydraulic cylinder is movably installed on one side of the connecting plate, with a plunger movably installed at the output end of the second hydraulic cylinder.

[0012] Preferably, the top of the plunger is hinged to a movable arm, the bottom of the movable arm is hinged to a mounting base, and a roller is movably mounted on one end of the movable arm.

[0013] The advantages of this utility model are:

[0014] This utility model, through the structural design of a movable fixing device, drives a servo motor, with the first sprocket driving the second sprocket to rotate via a chain. One side of the second sprocket is fixed to the rotating block, thereby causing the rotating block to rotate. One end of the rotating block drives the processing flange to rotate relative to it, realizing the function of flange rotation adjustment. This solves the problem of the flange being unable to move when fixed, and improves the limitations in use. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1-5 As shown, the flange processing fixture includes a base 1 and a movable fixing device 2. The movable fixing device 2 is equipped with a servo motor 21. A first sprocket 22 is fixedly installed at the output end of the servo motor 21. A chain 23 is driven to one side of the first sprocket 22, and a second sprocket 24 is driven to the other side of the chain 23. A rotating block 26 is fixedly installed on one side of the second sprocket 24, and a connecting seat 25 is movably installed through one side of the rotating block 26.

[0024] During operation, power is provided by servo motor 21, which drives the first sprocket 22 to rotate. The rotational power is transmitted to the rotating block 26 through the cooperation of the first sprocket 22, chain 23 and second sprocket 24.

[0025] Furthermore, a fixing frame 11 is installed on the base 1, and a working platform 12 is fixedly installed on the top of the fixing frame 11;

[0026] During operation, the fixed frame 11 provides appropriate support for the entire structure, ensuring that the work platform 12 has sufficient stability.

[0027] Furthermore, a machining flange 27 is movably connected to one side of the rotating block 26, and a limit block 28 is movably connected to the other end of the machining flange 27. A bearing 29 is movably installed on the other side of the limit block 28, and one side of the bearing 29 is fixedly installed at the output end of the first hydraulic cylinder 31.

[0028] During operation, a gap is created between the rotating block 26 and the limiting block 28. When the first hydraulic cylinder 31 is controlled, the bearing 29 drives the limiting block 28 to move to one side, adjusting the gap between the rotating block 26 and the limiting block 28, which is beneficial for limiting the machining flange 27.

[0029] Furthermore, a mounting base 37 is fixedly installed on the top of the working platform 12, a connecting base 25 is fixedly installed on the top of the working platform 12, a support base 32 is fixedly installed on the top of the working platform 12, and a first hydraulic cylinder 31 is fixedly installed through one side of the support base 32.

[0030] During operation, the connecting seat 25 and the support seat 32 are fixed by the work platform 12. When the processing flange 27 is limited, it ensures that other components have sufficient support, making the processing flange 27 more secure during processing.

[0031] Furthermore, a connecting plate 33 is fixedly installed on the top of the working platform 12, a second hydraulic cylinder 34 is movably installed on one side of the connecting plate 33, and a plunger 35 is movably installed at the output end of the second hydraulic cylinder 34.

[0032] During operation, the connecting plate 33 is installed on the working platform 12, so that the connecting plate 33 connects the second hydraulic cylinder 34. During operation, the second hydraulic cylinder 34 can rotate around the connection point of the connecting plate 33 as an axis.

[0033] Furthermore, the top of the plunger 35 is hinged to a movable arm 36, the bottom of the movable arm 36 is hinged to a mounting base 37, and a roller 38 is movably mounted on one end of the movable arm 36.

[0034] During operation, the plunger 35 moves in conjunction with the movable arm 36, causing it to rotate around the hinge of the mounting base 37. The installation of the roller 38 ensures that the machining flange 27 is limited without affecting its rotation.

[0035] Working principle: By placing the processing flange 27 between the rotating block 26 and the limiting block 28, the first hydraulic cylinder 31 is driven to move the output end of the bearing 29 and the limiting block 28 to one side, so that the rotating block 26 and the limiting block 28 limit both ends of the processing flange 27. Then, the second hydraulic cylinder 34 is driven to generate hydraulic energy to drive the plunger 35 to move outward, so that the plunger 35 links with the movable arm 36. At this time, the movable arm 36 moves in a circle around the hinge of the mounting base 37. When the roller 38 contacts one side of the processing flange 27, the drive of the second hydraulic cylinder 34 stops, so that the top of the processing flange 27 is limited by the roller 38 to prevent the processing flange 27 from falling off and flying upward during processing. During processing, the servo motor 21 can be driven to rotate the first sprocket 22, and the chain 23 drives the second sprocket 24 to rotate. The second sprocket 24 fixes the rotating block 26, so that one end of the rotating block 26 drives the processing flange 27 to rotate relative to it.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
