Description

Technical Field

[0001] The utility model relates to the technical field of equipment for processing rubber sealing rings, in particular to a fixing fixture for processing rubber sealing rings. Background Art

[0002] The rubber seal is an annular cover composed of one or more parts, fixed on a ring or washer of the bearing and in contact with another ring or washer or forming a narrow labyrinth gap to prevent lubricating oil leakage and foreign objects from intruding. During the production and processing of rubber seals, it is necessary to use a fixing fixture to clamp and fix the rubber seal.

[0003] At present, the existing equipment for clamping and fixing rubber sealing rings is generally a three-jaw chuck. Although it can effectively clamp and fix the rubber sealing ring, when clamping and fixing, it causes wear to the rubber sealing ring due to certain edges and corners on the clamping jaws, and even the edges and corners will scratch the rubber sealing ring, affecting the final product quality of the rubber sealing ring. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a fixing fixture for processing a rubber sealing ring, which is not easy to cause wear to the rubber sealing ring when clamping and fixing the rubber sealing ring.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0006] A fixing fixture for processing a rubber sealing ring comprises a mounting seat, a base plate, a rotating shaft, a rotating positioning structure, a connecting rod 1, a connecting rod 2, a sliding block and a cylindrical clamping block; the base plate is a disc structure and is rotatably connected to a rotating shaft at the center, a mounting seat is fixed to the rear side, the rotating shaft is driven to rotate by a rotating positioning structure arranged on the mounting seat, and is fixed by the rotating positioning structure after rotation, a plurality of connecting rods 1 evenly distributed along the circumferential direction are hinged on the side wall of the rotating shaft, the other end of the connecting rod 1 is hinged to a connecting rod 2, the other end of the connecting rod 2 is rotatably connected to a sliding block, the sliding block is connected to the base plate along a radial sliding direction of the base plate and passes through the base plate, and a clamping block is fixed to the front side of the sliding block.

[0007] As an improvement, the slider is an I-shaped plate structure, and a long strip of limiting through holes is opened on the base plate corresponding to each slider. After the middle plate of the slider passes through the limiting through holes, the two side plates are movably connected to the front and rear sides of the base plate.

[0008] As an improvement, the mounting seat is a U-shaped plate structure, and both ends are fixedly connected to the base plate respectively;

[0009] The rotary positioning structure includes a worm wheel and a worm with hand wheels fixed at both ends; the worm is rotatably connected to the two side plates of the mounting seat near the two ends, and a worm wheel matching the worm is sleeved and fixed on the rotating shaft, which is used to conveniently control the sliding blocks to slide synchronously along the strip-shaped through holes.

[0010] It is worth mentioning that the technical solution realizes the installation and fixation of the fixing fixture by installing and fixing the mounting seat to the rubber sealing ring processing tooling.

[0011] The advantages of the utility model compared with the prior art are:

[0012] 1. When the new type is in use, the sliders can be driven to slide synchronously along the corresponding strip-shaped through holes by rotating the hand wheel, thereby driving the clamping blocks to move synchronously toward the center of the substrate, or to the periphery of the substrate, to implement the action of clamping the rubber sealing ring, which is easy to operate.

[0013] 2. When the new type is in use, the clamping blocks are all cylindrical structures, which are not easy to cause wear to the rubber sealing ring when clamping and fixing it, effectively ensuring the final product quality of the rubber sealing ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In the description of the present utility model, it should be understood that the terms "center", "lateral", "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more. In addition, the term "including" and any variation thereof are intended to cover non-exclusive inclusions.

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] A fixing fixture for processing a rubber sealing ring, comprising:

[0022] Base plate 2, rotating shaft 3, connecting rod 1 4, connecting rod 2 5, slider 6 and cylindrical clamping block 7; Figure 1 , 3 As shown in 4, the base plate 2 is a disc structure, and a rotating shaft 3 is rotatably connected at the center. Six connecting rods 1 4 evenly distributed along the circumferential direction are hinged on the side wall of the rotating shaft 3. The other end of the connecting rod 1 4 is hinged to the connecting rod 2 5, and the other end of the connecting rod 2 5 is rotatably connected to the slider 6. The slider 6 is an I-shaped plate structure. Long strip-shaped limiting through holes 8 are respectively opened on the base plate 2 corresponding to each slider 6. After the middle plate body of the slider 6 passes through the limiting through hole 8, the two side plates are respectively movably connected to the front and rear side surfaces of the base plate 2. A clamping block 7 is fixed to the front side of the slider 6, and the side surface of the clamping block 7 is a rough surface;

[0023] Mounting seat 1 and rotation positioning structure; Figure 2 As shown, the mounting base 1 is a U-shaped plate structure, and its two ends are respectively fixedly connected to the base plate 2. The rotation positioning structure includes a worm wheel 9 and a worm 11 with hand wheels 10 fixed at both ends; the worm 11 is rotatably connected to the two side plates of the mounting base 1 near the two ends, and the worm wheel 9 matching the worm 11 is sleeved and fixed on the rotating shaft 3.

[0024] In the specific implementation of this embodiment:

[0025] Rotating any hand wheel 10 clockwise can drive each slider 6 to move synchronously toward the center of the substrate 2, and rotating any hand wheel 10 counterclockwise can drive each slider 6 to move synchronously toward the surrounding direction of the substrate 2, so that the rubber sealing ring can be clamped and fixed.

[0026] Since the cooperation between the worm wheel 9 and the worm 11 has a self-locking function, after the rubber sealing ring is clamped and fixed, the fixing fixture will always maintain the state of "clamping and fixing the rubber sealing ring" unless the hand wheel 10 is rotated to change it.

[0027] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
