Description

A positioning fixture for flange machining Technical Field

[0001] This utility model relates to the field of flange processing and positioning technology, and more specifically, to a positioning fixture for flange processing. Background Technology

[0002] A flange, also called a flange disc or flange, is commonly used for connections between shafts, pipe ends, or equipment. Generally speaking, a flange refers to a part or structure used for connection in the mechanical field. Flange machining lathes require flange machining positioning fixtures for assistance when in use.

[0003] Announcement No. CN222037635U proposes a positioning fixture for flange processing, which can achieve positioning during flange processing; however, both positioning and depositioning of the flange require manual operation, thus the ease of use of the positioning fixture needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a positioning fixture for flange processing.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A positioning fixture for flange processing includes a frame, a placement tray, a first telescopic component, a disc, a positioning roller, a cylindrical shell, a through hole, an automatic clamping assembly, a first circular hole, and a second circular hole.

[0007] The placement tray is fixed to the frame;

[0008] The four first circular holes are distributed around the circumference of the placement plate, and the second circular holes are opened at the center of the placement plate;

[0009] The first telescopic component is symmetrically fixed on the frame, and the first telescopic component is connected to a disc located below the placement tray.

[0010] The positioning rollers are distributed around the circumference of the disk, and the positioning rollers are directly aligned with the first circular holes and are sized to fit each other.

[0011] The cylindrical shell is fixed on the disk, and the cylindrical shell is directly opposite the second circular hole and the size is compatible.

[0012] The through holes are symmetrically arranged on the cylindrical shell;

[0013] The automatic clamping components are symmetrically fixed inside the cylindrical shell and move synchronously towards or away from each other along the through hole.

[0014] Furthermore, the automatic clamping assembly includes a mounting plate, a second telescopic member, and an arc-shaped plate.

[0015] The mounting plate is fixed inside the cylindrical shell;

[0016] The second expansion joint is symmetrically fixed on the mounting plate, and the second expansion joint is connected to an arc-shaped plate that fits against the inner wall of the flange center hole.

[0017] Furthermore, the surface of the positioning roller is covered with an anti-slip sleeve.

[0018] Furthermore, a rubber layer is fixed to the surface of the arc-shaped plate.

[0019] In the above solution, the anti-slip sleeve and rubber layer can protect the flange surface from wear during clamping.

[0020] Furthermore, a distance sensor is provided on the disk.

[0021] The above solution can more accurately limit the rising and falling range of the positioning roller and the cylindrical shell by using a distance sensor, avoiding large errors that could affect the automatic positioning effect of the flange.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] Compared to existing technologies, this device only requires placing the flange between four positioning rollers to automatically and efficiently clamp and position the flange, improving automation and making it more convenient. At the same time, it can automatically release the fixing after the flange processing is completed, making material removal convenient and the positioning tooling more user-friendly.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0031] As shown in Figures 1 and 2, a positioning fixture for flange processing includes a frame 1, a placement plate 2, a first telescopic component 3, a disc 4, a positioning roller 5, a cylindrical shell 6, a through hole 7, an automatic clamping assembly, a first circular hole 8, and a second circular hole 9.

[0032] The placement tray 2 is fixed on the frame 1;

[0033] Four first circular holes 8 are distributed around the circumference of the placement plate 2, and the second circular holes 9 are opened in the center of the placement plate 2;

[0034] The first telescopic component 3 is symmetrically fixed on the frame 1, and the first telescopic component 3 is connected to the disc 4 located below the placement disc 2;

[0035] The positioning rollers 5 are distributed around the circumference of the disk 4 and are directly aligned with the first circular holes 8 and are sized to fit each other.

[0036] The cylindrical shell 6 is fixed on the disk 4, and the cylindrical shell 6 is directly opposite the second circular hole 9 and the size is compatible.

[0037] Through holes 7 are symmetrically formed on the cylindrical shell 6;

[0038] The automatic clamping components are symmetrically fixed inside the cylindrical shell 6 and move synchronously towards or away from each other along the through hole 7.

[0039] As shown in Figure 1, the automatic clamping assembly includes a mounting plate 10, a second telescopic member 11, and an arc-shaped plate 12.

[0040] Mounting plate 10 is fixed inside cylindrical shell 6;

[0041] The second expansion joint 11 is symmetrically fixed on the mounting plate 10, and the second expansion joint 11 is connected to an arc-shaped plate 12 that fits against the inner wall of the flange center hole.

[0042] In a further refinement of the embodiment of this utility model, the surface of the positioning roller 5 is fitted with an anti-slip sleeve (not shown in the figure), and the surface of the arc plate 12 is fixed with a rubber layer (not shown in the figure). The anti-slip sleeve and the rubber layer can protect the flange surface from wear during the clamping process.

[0043] It should be noted that both the first telescopic component 3 and the second telescopic component 11 are electrically connected to the controller, which is not labeled in the figure.

[0044] The working process of this utility model is as follows:

[0045] The initial position of the positioning roller 5 is shown in Figure 1 of the instruction manual. At this time, the flange of the fixed specification can be placed directly between the four positioning rollers 5 to achieve accurate and rapid positioning (i.e., the outer wall of the flange is in contact with the four positioning rollers 5). At the same time, the cylindrical shell 6 can pass through the center hole of the flange and be concentric with the center hole of the flange. Then, the controller controls the second telescopic component 11 to operate synchronously, which drives the two arc plates 12 to pass through the through hole 7 and move outward synchronously and fit against the inner wall of the center hole of the flange to press against the external support. Then, under the limitation of the arc plate 12 and the positioning roller 5, the flange can be effectively positioned on the placement plate 2. Then, the surface of the flange can be processed by the processing equipment. The flange will not shift during the processing.

[0046] After the flange processing is completed, the controller controls the movement of the second telescopic component 11 to release the clamping and positioning of the inner wall of the flange center hole and store it inside the cylindrical shell 6. Then, the controller controls the movement of the first telescopic component 3 so that the upper surface of the positioning roller 5 and the upper surface of the cylindrical shell 6 are flush with the surface of the placement plate 2. This is to facilitate the cleaning of debris or other foreign objects on the surface of the placement plate 2. After cleaning is completed, the positioning roller 5 and the cylindrical shell 6 are reset and a new round of flange positioning processing can begin.

[0047] Compared to existing technologies, this device only requires placing the flange between four positioning rollers 5 to automatically and efficiently clamp and position the flange, improving automation and making it more convenient. At the same time, it can automatically release the fixing after the flange processing is completed, making material removal convenient and the positioning tooling more user-friendly.

[0048] In some embodiments, as shown in FIG3, a distance sensor 13 is provided on the disc 4; in this embodiment, the distance sensor 13 measures the distance between the bottom surfaces of the placement disc 2 in real time, thereby more accurately limiting the rising and falling range of the positioning roller 5 and the cylindrical shell 6, avoiding large errors that affect the automatic positioning effect of the flange.

[0049] 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 descriptions of the above embodiments and specifications 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 protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
