Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a workpiece placement and fixing device for machining. Background Technology

[0002] like Figure 3 The diagram shows a three-dimensional structural view of a workpiece used in electrical distribution equipment. The workpiece includes a rectangular column 9 with a circular groove 90 formed along its length. Several through holes 91 are formed through the two opposite side walls of the column 9. The circular grooves 90 and through holes 91 are machined using a machine tool. After machining, the inner wall has many burrs and other defects. Conventional methods include fine grinding, but this increases the cost of machining the workpiece. Furthermore, the workpiece has relatively low requirements for the roughness of the inner walls of the circular grooves 90 and through holes 91; therefore, manual deburring is currently commonly used, which is faster. However, due to the large size of the workpiece, it is inconvenient for operators to hold and remove burrs. It is often placed on a workbench, and the inability to adjust the workpiece's posture further complicates burr removal. Utility Model Content

[0003] This utility model provides a workpiece placement and fixing device to solve the shortcomings of the prior art, such as the inconvenience of adjusting the workpiece posture during burr removal, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A workpiece placement and fixing fixture includes a base plate with a pair of side plates welded to both sides. A rotating shaft is rotatably mounted at one end of each side plate, and a rotating recess is welded to the inner end of the rotating shaft, located between the side plates. A pair of vertical rods are welded to the transverse section of the rotating recess, and a connecting plate is welded to each vertical rod. An inner plate is welded to the inner end of the connecting plate, and end plates are welded to both ends of the inner plate. A pair of transverse holes are provided on the end plates, and movable screws are movably mounted within these holes. One end of each movable screw on the same side is threadedly connected to a clamping side plate, and the other end of the clamping side plate is bent inwardly with a constraint strip. The other end of each movable screw on the same side is threadedly connected to a... An inner movable plate is connected to a movable rod via a thread. A movable protruding plate is fitted onto the lower end of the vertical rod. A concave plate is welded to the inner end of the movable protruding plate. A limit lower plate is welded to the horizontal section of the concave plate. A rectangular plate is formed at the upper end of the vertical section of the concave plate. An oblique hole is opened on the rectangular plate. The movable rod passes through the oblique hole. The upper end of the oblique hole extends inward at an incline. A spring is fitted onto the lower end of the vertical rod. The spring is located between the rotating concave seat and the movable protruding plate. A pair of limit nuts are connected to the upper end of the vertical rod via a thread. A limit upper plate is fitted onto the upper end of the vertical rod. An oblong hole is opened on the limit upper plate. The upper end of the vertical rod passes through the oblong hole. The limit nuts are located on the upper and lower sides of the limit upper plate.

[0005] Furthermore, an outer nut is threaded onto the outer end of the shaft, and the outer nut is located on the outer side of the side plate.

[0006] Furthermore, an inner protruding rod is welded to the inner wall of the side plate, which is used to limit the rotation of the rotating recess.

[0007] Furthermore, a constraint nut is threadedly connected to the outer end of the moving rod, and the constraint nut is located on the outer side of the rectangular plate.

[0008] The advantages of the above technical solution are: This utility model indirectly places and fixes the workpiece on a rotating recess, which facilitates the rotation of the workpiece. During rotation, the inner protrusion rod limits the rotation, allowing the workpiece to be tilted. This makes it easier for the operator to clean the inner wall of the circular groove. At the same time, rotating the workpiece as a whole facilitates the deburring of the perforation.

[0009] This invention provides stable constraint on a workpiece. The two ends of the workpiece are limited by a lower limiting plate and an upper limiting plate, respectively, while the front and rear sides are limited by constraint strips and an inner plate. The left and right sides are limited by clamping side plates. Furthermore, the constraint does not obstruct the openings of the perforations and grooves, facilitating burr removal. Additionally, the spring force enhances the stability of the constraint during fixing. Attached Figure Description

[0013] Figure 3 A three-dimensional structural diagram of the workpiece is shown. Detailed Implementation

[0014] like Figures 1-3As shown, a workpiece placement and fixing device includes a base plate 1. A pair of side plates 10 are welded to both sides of the base plate 1. A rotating shaft 11 is rotatably mounted at one end of each side plate 10. A rotating recess 12 is welded to the inner end of the rotating shaft 11. An outer nut is threaded to the outer end of the rotating shaft 11, located outside the side plates 10. The rotating recess 12 is located between the side plates 10. An inner protruding rod 13 is welded to the inner wall of each side plate 10, serving as a rotation limiter for the rotating recess 12. A pair of vertical rods 14 are welded to the transverse section of the seat 12. A connecting plate 2 is welded to the vertical rods 14. An inner plate 20 is welded to the inner end of the connecting plate 2. End plates 21 are welded to both ends of the inner plate 20. A pair of transverse holes 22 are provided on the end plates 21. Movable screws 23 are movably installed in the transverse holes 22. One end of the movable screws 23 on the same side is threaded to a clamping side plate 32. The other end of the clamping side plate 32 is bent inward and has a constraint strip 33. The other end is connected to an inner movable plate 24 via a thread. A moving rod 25 is connected to the inner movable plate 24 via a thread. A movable protruding plate 30 is fitted onto the lower end of the vertical rod 14. A concave plate 28 is welded to the inner end of the movable protruding plate 30. A limit lower plate 29 is welded to the horizontal section of the concave plate 28. A rectangular plate 26 is formed at the upper end of the vertical section of the concave plate 28. An oblique hole 27 is opened on the rectangular plate 26. The moving rod 25 passes through the oblique hole 27. A constraint nut is connected to the outer end of the moving rod 25 via a thread. The constraint nut is located on the outside of the rectangular plate 26. The upper end of the inclined hole 27 extends inward at an inclination. The lower end of the vertical rod 14 is fitted with a spring 31. The spring 31 is located between the rotating recess 12 and the moving convex plate 30. The upper end of the vertical rod 14 is connected to a pair of limit nuts 34 by threads. The upper end of the vertical rod 14 is fitted with a limit plate 35. The limit plate 35 has an oblong hole 36. The upper end of the vertical rod 14 passes through the oblong hole 36. The limit nuts 34 are located on the upper and lower sides of the limit plate 35.

[0015] In this embodiment, the operator places the workpiece on the lower limiting plate 29, ensuring that the opening of the circular groove 90 faces upwards and the back of the workpiece abuts against the inner wall of the inner plate 20. Then, the operator presses the workpiece downwards, causing the lower limiting plate 29 and the movable protrusion 30 to move downwards. When the movable protrusion 30 moves downwards, the spring 31 is compressed, and the rectangular plate 26 moves downwards. As the rectangular plate 26 moves, it acts on the moving rod 25 through the oblique hole 27, thereby causing the inner movable plate 24 and the clamping side... The plate 32 moves inward, causing the inner wall of the clamping side plate 32 to abut against both sides of the workpiece until the workpiece can no longer move downward. Then, the upper limiting plate 35 is moved to limit and constrain the upper end of the workpiece. After that, the operator rotates the workpiece around the rotating shaft 11, so that the circular groove 90 of the workpiece faces the operator. At the same time, the inner protrusion 13 limits the rotation of the rotating recess 12. Then, the operator performs deburring. Since the workpiece is tilted, it is convenient for the operator to perform deburring.

Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
