Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, and in particular to a shovel platform fixture. Background Technology

[0002] Scraping is a high-precision metal surface repair and mating technique. It involves manually removing high points from the workpiece surface using a scraper, achieving a specific contact point density (e.g., 20-30 points per square inch) between the workpiece and a reference plane. During this process, the workpiece must be stably and precisely supported on a horizontal reference surface to ensure scraping accuracy. Traditional methods typically use a fixed platform or shims, manually adjusting the shims beneath the workpiece repeatedly to achieve levelness. This method is inefficient, the adjustment accuracy is highly dependent on the operator's experience, and it is difficult to maintain stability during operation, directly affecting scraping quality and efficiency. Therefore, a scraping platform fixture capable of precisely adjusting the workpiece level and stably fixing it is needed. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to solve the problem of low workpiece adjustment accuracy and low efficiency in the prior art, this utility model provides a scraping platform fixture.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a scraping platform fixture, including a bottom base, a three-jaw leveling platform, a workpiece bearing platform and a movable connecting mechanism; at least four three-jaw leveling platforms are provided, which are connected to the upper end of the bottom base through the movable connecting mechanism; the workpiece bearing platform is set on the three-jaw leveling platform, and a locking mechanism is provided between the workpiece bearing platform and the three-jaw leveling platform.

[0005] Furthermore, the movable connection mechanism includes a first axis, a second axis, a third axis, a fourth axis, and a fifth axis; the first axis, the second axis, the third axis, the fourth axis, and the fifth axis connect the three-jaw leveling platform and the bottom base.

[0006] Furthermore, the locking mechanism includes a locking bolt with an external hexagonal head at the end, which passes through the bottom base or the three-jaw leveling platform. The locking bolt is tightened or loosened by turning it to achieve fine-tuning and locking functions.

[0007] Furthermore, the bottom base is symmetrically provided with bracket adjustment mechanisms on both sides along its length. The bracket adjustment mechanism includes a fixed support, a rotating support, and a fixing bolt; the fixed support is fixedly connected to the bottom base.

[0008] Furthermore, the rotating bracket is rotatably connected to the fixed support, and the rotating bracket is provided with an arc-shaped waist hole, through which the fixing bolt passes and is threadedly connected to the fixed support.

[0009] Furthermore, the workpiece carrying platform is a scraping platform used to directly place the workpiece to be scraped.

[0010] The beneficial effects of this utility model are: The scraping platform fixture described in this utility model uses four three-jaw platforms with movable joints to achieve rapid initial leveling by utilizing the workpiece's own weight, greatly reducing the time required for traditional manual leveling. Combined with automatic leveling and manual fine-tuning, it can achieve extremely high horizontal accuracy, and the locking bolts ensure stability during operation, guaranteeing the quality of scraping.

[0013] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0014] In the description of this utility model, it should be understood that the terms "upper", "lower", "horizontal", "top", "inner", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] like Figure 1-3 As shown, a scraping platform fixture includes a bottom base 1, a three-jaw leveling platform 2, a workpiece bearing platform 3, and a movable connecting mechanism 4; at least four three-jaw leveling platforms 2 are provided, which are connected to the upper end of the bottom base 1 through the movable connecting mechanism 4; the workpiece bearing platform 3 is set on the three-jaw leveling platform 2, and a locking mechanism 5 is provided between the workpiece bearing platform and the three-jaw leveling platform 2.

[0017] The movable connection mechanism 4 includes a first axis 41, a second axis 42, a third axis 43, a fourth axis 44, and a fifth axis 45; the first axis 41, the second axis 42, the third axis 43, the fourth axis 44, and the fifth axis 45 connect the three-jaw leveling platform 2 and the bottom base 1. The locking mechanism 5 includes a locking bolt 51, the end of which has an external hexagonal head that passes through the bottom base 1 or the three-jaw leveling platform 2. By tightening the locking bolt 51, the workpiece bearing platform 3 is tightened or loosened to achieve fine-tuning leveling and locking functions.

[0018] The bottom base 1 is symmetrically equipped with bracket adjustment mechanisms 61 on both sides along its length. Each bracket adjustment mechanism 61 includes a fixed support 61, a rotating support 62, and fixing bolts 63. The fixed support 61 is fixedly connected to the bottom base 1. The rotating support 62 is rotatably connected to the fixed support 61. The rotating support 62 has an arc-shaped waist hole 64, through which the fixing bolts 63 are threadedly connected to the fixed support 61. The workpiece bearing platform 3 is a scraping platform used to directly place the workpiece to be scraped.

[0019] When performing scraping operations, first place the workpiece support platform 3 (or simply the standard scraping platform) on the four three-jaw leveling platforms 2. Then, hoist the workpiece to be processed onto the workpiece support platform 3. Under the weight of the workpiece, the movable joints of the four three-jaw leveling platforms 2 will automatically adjust their angles, so that the workpiece support platform 3 reaches a preliminary level state.

[0020] After initial leveling, the operator uses tools to tighten the locking bolts 51 distributed around the platform. These bolts have hexagonal heads at the ends for easy operation. By finely adjusting the screw depth of each bolt, the levelness of the workpiece bearing platform 3 can be precisely corrected. Once the levelness meets the process requirements, all locking bolts 51 are thoroughly tightened, thereby firmly fixing the workpiece bearing platform 3 and the workpiece on it, forming a stable and accurate scraping reference surface.

[0021] In this specification, the illustrative expressions of the terms do not necessarily refer to the same embodiments. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments.

[0022] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
