Description

Technical Field

[0001] The utility model belongs to the technical field of workpiece processing, and in particular relates to a positioning tool for deburring which is easy to clean. Background Art

[0002] Burrs are the burrs and flash that occur during all machining processes, including casting, forging, sintering, welding, gasification, blanking, cutting, grinding, electroplating, painting, and insulation coating. These burrs and flash appear on the surface or at the edges of the machined part, creating protrusions that deviate from the designed shape and are undesirable in terms of both part performance and appearance. Mechanical deburring is the oldest and most widely used method, primarily including manual deburring, tumbling, brushing, and high-pressure water jetting. Currently, brush deburring is widely used in industrial production for deburring medium- and large-sized plate-shaped workpieces due to its low cost and minimal ongoing maintenance. Brush deburring technology uses a specially designed brush, driven by power (or manual) rotation, to effectively grind and deburr the workpiece surface while simultaneously performing multiple functions, including chamfering, micro-finishing, and polishing. Its flexibility allows the brush to adapt to complex workpiece shapes and effectively remove burrs from edges. However, in actual operation, the workpiece needs to be manually flipped for clamping and fixing, which not only reduces work efficiency, but also easily splashes the residue generated during the cleaning process into the surrounding area, causing inconvenience in subsequent cleanup. To this end, the present utility model designs a positioning fixture for deburring that is easy to clean. It aims to achieve automatic flipping of plate-shaped workpieces, thereby improving the efficiency of deburring operations, improving work efficiency during the workpiece flipping process, reducing the labor intensity of operators, and at the same time, reducing the burden of subsequent cleanup work.

[0003] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] Example

[0017] See also Figure 1-2 The present invention provides the following technical solution: a positioning fixture for deburring that facilitates cleaning, comprising a grid work table 1 with a clearance groove 2 defined on the top surface of the grid work table 1 to accommodate a flip frame 3 and prevent the flip frame 3 from interfering with the grid work table 1 during flipping. Clamps are installed on both sides of the flip frame 3 to ensure the stability of the plate-shaped workpiece during processing. Connecting shafts 14 are fixed to each end of the flip frame 3, while bearing blocks 4 are mounted on both ends of the clearance groove 2 of the grid work table 1. The coupling between the connecting shafts 14 and the bearing blocks 4 enables a flexible and stable rotational connection between the flip frame 3 and the grid work table 1. Furthermore, the connecting shaft 14 at one end of the flip frame 3 is equipped with a drive assembly for driving the flip frame 3 to flip, enabling rapid and automatic workpiece flipping. To effectively collect and dispose of waste and burrs generated during processing, a slag hopper 5 is welded to the bottom of the grid work table 1. The slag hopper 5 is connected to the slag box 7 via a discharge pipe 6, forming a complete waste collection structure. On one side of the discharge pipe 6, an air duct 8 is cleverly connected. A filter is installed inside the air duct 8 to prevent waste from entering the fan 9 and affecting its normal operation. The fan 9 is connected to the discharge pipe 6 through the air duct 8, using wind power to assist in the rapid discharge and collection of waste.

[0018] In order to facilitate the quick operation of fixing the workpiece, in this embodiment, as an optimal technical solution of the utility model, the clamp includes a hand-tightening bolt 10, the threaded section of the hand-tightening bolt 10 is threadedly connected to the edge of the flip frame 3, and the end of the hand-tightening bolt 10 is rotatably connected to a clamping part 11, and the inner wall of the clamping part 11 is evenly provided with anti-slip grooves.

[0019] In order to improve the stability of the flip frame 3 during the deburring process and facilitate the fixation of the flip frame 3, in this embodiment, as a preferred technical solution of the present invention, the driving component includes a self-locking motor 12, and the output end of the self-locking motor 12 is installed with a reduction gear box 13, and the output end of the reduction gear box 13 is connected to the connecting shaft 14 at one end of the flip frame 3.

[0020] In order to prevent the debris from damaging the fan 9 and prevent the debris from overflowing, in this embodiment, as a preferred technical solution of the utility model, the filter includes a box body 15, a filter element 16 is installed inside the box body 15, and the connection between the two ends of the box body 15 and the air duct 8 is a detachable structure.

[0021] In order to support the whole, in this embodiment, as a preferred technical solution of the present utility model, support plates 17 are fixed on both sides of the slag receiving hopper 5 at the bottom of the grid workbench 1.

[0022] In order to facilitate the centralized processing of the debris entering the slag receiving box 7 , in this embodiment, as a preferred technical solution of the present invention, the interior of the slag receiving box 7 is connected to an aggregate box 18 by plugging.

[0023] In summary, according to the technical solution of the present invention, the specific operation is as follows: the plate-shaped workpiece to be processed is placed inside the turning frame 3. Then, by rotating the hand-tightening bolts 10 installed on the edge of the turning frame 3, the clamping members 11 are screwed inward until they firmly abut the edge of the plate-shaped workpiece. This process effectively utilizes the clamping members 11 on both sides of the turning frame 3 to securely secure the plate-shaped workpiece. Next, the workpiece surface is treated with a brush, while the fan 9 system is activated. The fan 9, through the synergistic effect of the air duct 8 and the slag hopper 5, generates a strong suction force in the area of ​​the grid workbench 1. This suction force quickly absorbs impurities such as burrs, slag, and debris generated by the brush during the workpiece surface treatment process and directs them into the slag hopper 5. Larger debris is directly collected through the discharge pipe 6 into the collection box 18 of the slag box 7. Smaller debris, on the other hand, is filtered and isolated through the air duct 8 and enters the filter for subsequent unified disposal. After the surface treatment of one side of the workpiece is completed, the output power of the self-locking motor 12 is transmitted through the reduction gear box 13, and finally driven by the connecting shaft 14 to realize the synchronous flipping of the flip frame 3 together with the workpiece, thereby facilitating the surface burr treatment of the other side of the workpiece.

[0024] Finally, it should be noted that in the present invention, unless otherwise clearly stipulated and limited, terms such as "installation", "setting", "connection", "fixation", and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated 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; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0025] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
