Description

Technical Field

[0001] This utility model belongs to the field of flange processing technology, and in particular relates to a flange processing circular cutting fixture. Background Technology

[0002] A flange, also known as a disc, is a disc-shaped metal body with several holes around its perimeter for fixing and connecting other components. During the production and processing of flanges, the holes need to be rounded, chamfered, and deburred.

[0003] According to prior art, application (announcement) number CN220762158U discloses a flange processing device, which "includes a machine base, the upper surface of the machine base is provided with a rotating component for changing the processing position of a flange, the upper surface of the machine base is provided with a circular cutting component for processing the flange, and the outer side of the rotating component is provided with a number of clamping components for clamping and fixing the flange in a ring". It has the technical effect that "by using the rotating component and the circular cutting component together, flanges of different specifications and sizes can be processed. In the circular cutting component, the position of the grinding part is changed by the drive screw 2 of motor 3. Then, in the rotating component, the rotating plate is rotated by the meshing transmission of bevel gear 1 and bevel gear 2 of motor 2, which can drive the flange to rotate, so that the grinding part can better perform circular cutting processing on the several holes arranged in a ring on the surface of the flange".

[0004] Firstly, the clamping plates in this device are all of the same model. When the flange size changes, the clamping plates need to be disassembled and replaced with suitable clamping plates, which is troublesome and not conducive to small-batch production of multiple models. Moreover, there are only 2 clamping plates, which makes it difficult to ensure stable clamping of the flange during processing, resulting in flange displacement, affecting quality, and also posing certain safety hazards.

[0005] To address the aforementioned issues, this application proposes a flange machining circular cutting fixture. Utility Model Content

[0006] The purpose of this utility model is to provide a flange processing circular cutting fixture, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a flange processing circular cutting fixture, comprising a rotating seat and a turntable rotatably connected to the rotating seat.

[0028] 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 protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] Please see Figure 1 - Figure 5 As shown, this utility model is a flange processing circular cutting fixture, including a rotating seat 1 and a turntable 2 rotatably connected to the rotating seat 1. The rotating seat 1 is fixed to the circular cutting device through a fixed sleeve 11. The turntable 2 is connected to the circular cutting device through a transmission shaft 21. A sliding slider 3 is provided on the turntable 2 in the radial direction. At least three sliders 3 are also provided along the circumference of the turntable 2. An adapter sleeve 6 is fixed on one side of the slider 3. A rotating sleeve 7 is movably connected to the outside of the adapter sleeve 6. Several clamping plates 72 arranged in the circumferential direction are fixed on the rotating sleeve 7 through a connecting rod 71. In this embodiment, the clamping plates 72 are arc-shaped structures. The length of each connecting rod 71 is different. When the clamping plates 72 of the same model are rotated to the clamping position, the annular space formed by the inner side of the multiple clamping plates 72 is adapted to the size of the flange being clamped. There is no need to adjust the position of the clamping plates 72 on the connecting rod 71 according to the different flange sizes.

[0031] Specifically, in order to enable quick rotation and switching between different models of clamping plates 72, the adapter sleeve 6 has an adjustment groove 62 circumferentially opened on its outer side, and a locking groove 63 with the same number as the clamping plate 72 is opened radially on its outer side. The locking groove 63 and the adjustment groove 62 are interconnected. A sliding screw 74 is connected to the rotating sleeve 7 through a threaded hole 73. The front end of the threaded hole 73 slides in the adjustment groove 62 and the locking groove 63. In this embodiment, the sliding screw 74 can rotate freely in the adjustment groove 62 to adjust the position of different models of clamping plates 72. After the sliding screw 74 enters the locking groove 63, it cannot rotate, which serves the purpose of convenient locking. Moreover, the way to slide the sliding screw 74 from the locking groove 63 to the adjustment groove 62 is by pulling, which is opposite to the direction of the thrust generated by machining, ensuring locking stability.

[0032] More specifically, such as Figure 1As shown, during machining, the machining equipment is located on the left side. The equipment will generate a certain forward thrust during machining. The rotating sleeve 7 and the transition sleeve 6 under the direction of this thrust are in a completely opposing state and cannot be driven to produce radial relative displacement.

[0033] Specifically, in order to enable the rotating sleeve 7 to flexibly cooperate with the adapter sleeve 6, the adapter sleeve 6 is provided with a spring groove 61 on the side near the slider 3, and a polygonal hole communicating with the spring groove 61 is also provided through the adapter sleeve 6. A polygonal rod 8 is provided in the polygonal hole along the axial direction. The cooperation between the polygonal rod 8 and the polygonal hole prevents the polygonal rod 8 from rotating synchronously when the rotating sleeve 7 rotates.

[0034] A locking spring 9 is fitted outside the polygonal rod 8 located in the spring groove 61. A first screw 81 is fixed to one end of the polygonal rod 8 near the slider 3, and the other end of the polygonal rod 8 abuts against the inner side of the rotating sleeve 7. A second screw 82 is fixed to one side of the polygonal rod 8 near the rotating sleeve 7. In this embodiment, the locking spring 9 abuts between the first screw 81 and the inside of the spring groove 61. The rebound force of the locking spring 9 can drive the rotating sleeve 7 to move outward of the adapter sleeve 6, which is used to automatically lock the slider screw 74 and the locking groove 63.

[0035] Assembly of slider 3, adapter sleeve 6, rotating sleeve 7, polygonal rod 8, and locking spring 9: The polygonal rod 8 passes through the polygonal hole in the adapter sleeve 6 from one end of the spring groove 61. The locking spring 9 is sleeved on the outside of the polygonal rod 8 and placed in the spring groove 61. The first screw 81 is screwed and fixed to one end of the polygonal rod 8 and can slide inside the spring groove 61. The rotating sleeve 7 is sleeved on the outside of the adapter sleeve 6. The second screw 82 is screwed and pressed against the other end of the polygonal rod 8 from the outside of the rotating sleeve 7. It should be noted that after the second screw 82 is screwed, it is pressed against the polygonal rod 8. At this time, a rotation space for the rotating sleeve 7 is formed between the second screw 82 and the polygonal rod 8. Then, the sliding rod screw 74 is screwed into the threaded hole 73 in sequence. The smooth part at the front end of the sliding rod screw 74 is located in the adjustment groove 62 or the locking groove 63. The assembly is completed.

[0036] Furthermore, in order to ensure the radial movement stability of the slider 3, a groove 24 is provided on the turntable 2 to slide and connect with the slider 3. In order to facilitate the assembly and maintenance of the slider 3, the upper end of the groove 24 is open. A side cover plate 25 for the groove 24 is fixed on the side of the turntable 2, and the opening on the groove 24 is blocked by the side cover plate 25.

[0037] Furthermore, in order to move multiple sliders 3 synchronously on the turntable 2, a groove 22 is provided at one end of the turntable 2. A front cover plate 23 is installed in the groove 22, and a rotating conical gear disk 5 is provided in the groove 22. A threaded screw 4 is passed through the slider 3. A conical transmission gear 41 is fixed at one end of the screw 4 and meshes with the conical gear disk 5. The conical transmission gears 41 on the three screws 4 mesh with the conical gear disk 5 at the same time. The other end of one of the screws 4 is fixed with a screw wheel 10 located outside the turntable 2. The linkage mechanism in this embodiment enables all sliders 3 to move synchronously and in the same direction, so that the flange can be clamped at multiple points at the same time under the action of the connecting rod 71, ensuring clamping accuracy.

[0038] Furthermore, to ensure smooth adjustment of the clamping plate 72, the slide screw 74 is provided with a threaded part and a smooth part. The diameter of the smooth part is smaller than that of the threaded part. The threaded part is threadedly connected to the threaded hole 73, and the smooth part slides in the adjustment groove 62 and the locking groove 63. The smooth part is used for sliding engagement, so that the rotating sleeve 7 can move smoothly outside the adapter sleeve 6 and avoid jamming.

[0039] Furthermore, in order to increase the fitting length between the slide screw 74 and the locking groove 63, the locking groove 63 is chamfered at one end near the adjusting groove 62. That is to say, when the slide screw 74 is in the chamfered position, it can automatically be inserted into the locking groove 63 under the action of the locking spring 9, without the need for precise alignment, making the operation more convenient.

[0040] It is understood that this utility model achieves rapid switching through the rotating sleeve and multiple different types of clamping plates at its upper end, which can flexibly adapt to the processing requirements of flanges of different sizes; at the same time, at least 3 clamping plates of each type are set, which, combined with the transmission mechanism of the lead screw and bevel gear disk, ensure clamping stability and synchronization accuracy, and improve processing efficiency and reliability.

[0041] One specific application of this embodiment is that the fixed sleeve 11 is fixedly installed with the device, and the turntable 2 is rotatably connected to the equipment through the transmission shaft 21.

[0042] Flange clamping: Place the flange within the clamping range of the connecting rod 71. The flange is supported between the two connecting rods 71 ​​at the lower end. At this time, rotate the lead screw 4 through the screw wheel 10. The lead screw 4 is driven to rotate synchronously through the bevel gear disk 5. The lead screw 4 drives all the connecting rods 71 ​​to move towards the axis through the screw of the slider 3. Finally, the flange is clamped between the three connecting rods 71. Tighten the screw wheel 10 again to strengthen the clamping stability.

[0043] In this state, the drive mechanism on the device, in cooperation with the transmission shaft 21, can drive the turntable 2 to rotate on the rotating seat 1 to perform circular cutting processing.

[0044] Switching of link 71: such as Figure 4As shown, the rotating sleeve 7 is pulled outward along the axis of the adapter sleeve 6, the locking spring 9 is compressed, and the slide screw 74 moves from the locking groove 63 to the adjusting groove 62. The rotating sleeve 7 is rotated outside the adapter sleeve 6 and the polygonal rod 8, changing the position of the connecting rod 71. The required connecting rod 71 is adjusted to correspond to the axis of the turntable 2. The rotating sleeve 7 is released, and under the action of the locking spring 9, the slide screw 74 is moved from the adjusting groove 62 to the locking groove 63, thus completing the automatic locking after the connecting rod 71 is switched.
