[0002] Tooling fixtures are devices used in the mechanical manufacturing process to fix the workpiece in the correct position for construction or inspection. In a broad sense, any device used to quickly, conveniently and safely install a workpiece in any step of the process can be called a tooling fixture, such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc.

[0003] Utility model patent CN215391648U discloses a tooling for manufacturing rounded corners, including a fixed base and a rotating part limiting component. A rotatable shaft is engaged at the center of the upper surface of the fixed base. A rotating part limiting component for processing sheet metal is fixedly connected to one side of the upper surface of the fixed base. A collar that can slide along the outside of the shaft is sleeved on the outside of the shaft. A push rod is fixedly connected to the side of the collar. A sleeve rod that can slide along the push rod is sleeved on the outside of the push rod. A bracket is fixedly connected to the side of the sleeve rod. A round rod is fixedly connected to the side of the bracket. An extrusion component for extruding sheet metal is engaged at the bottom end of the round rod. When manufacturing curved sheet metal, the extrusion component extrudes at the front end. After the workpiece at the rear end is bent and loses its restraint, it may warp due to the lack of restraint, leading to defects when extruding curved sheet metal. Therefore, further improvement of the rounded corner manufacturing tooling is necessary. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tooling for manufacturing radius (R) angles includes a fixed base, a rotating shaft rotatably disposed at the center of the upper surface of the fixed base, and a rotating part limiting member fixed to one side of the upper surface of the fixed base. It also includes a vertical rod and a pressing member fixed to the lower end of the vertical rod. The vertical rod is connected to the rotating shaft via a first connecting rod located above the rotating part limiting member. A limiting block located on one side of the rotating part limiting member is fixed to the upper surface of the fixed base. A plate positioning block is disposed between the limiting block and the rotating part limiting member, with the plate positioning block facing the rotating part. One side of the limiting member is provided with a plate positioning hole, which is used to press one end of the plate against one side of the rotating limiting member through the plate positioning hole; the extrusion member is located between the plate positioning block and the rotating limiting member, and the extrusion member is connected to the plate positioning block in a transmission manner. When the extrusion member rotates from one side of the rotating limiting member to the other side, it can drive the plate positioning block to press against one side of the rotating limiting member; when the extrusion member rotates towards the limiting block, it can drive the plate positioning block to disengage from one side of the rotating limiting member and abut against the limiting block.

[0007] As a preferred technical solution of this utility model, an arc-shaped rack is provided on the outside of the fixed base with the rotating shaft as the central axis. One end of the arc-shaped rack is fixedly connected to the vertical rod, and the other end of the arc-shaped rack is connected to the rotating shaft through the second connecting rod. An arc-shaped limiting hole is provided in the plate positioning block. A gear is rotatably connected to one side of the arc-shaped limiting hole. The arc-shaped rack passes through the arc-shaped limiting hole, and the inner side of the arc-shaped rack is matched and meshed with the gear. The outer side of the arc-shaped rack is slidably engaged with the other side of the arc-shaped limiting hole.

[0008] As a preferred technical solution of this utility model, the plate positioning block includes an upper positioning block and a lower positioning block connected by a first bolt, an arc-shaped limiting hole is located between the upper positioning block and the lower positioning block, and a gear receiving groove is provided on one side of the arc-shaped limiting hole, and the gear is rotatably connected in the gear receiving groove.

[0009] As a preferred technical solution of this utility model, the upper surface of the fixed base is provided with an arc-shaped slide rail located between the limiting block and the rotating part limiting part, and the lower end of the plate positioning block is provided with an arc-shaped slide groove, which slides in cooperation with the arc-shaped slide rail.

[0010] In a preferred embodiment of this invention, the extrusion component is a ball bearing, and the inner ring of the extrusion component is connected to the lower end of the vertical rod.

[0011] As a preferred technical solution of this utility model, the lower end of the vertical rod is provided with a vertical limiting groove, and the inner ring of the extrusion part is provided with a vertical limiting block. The vertical limiting block slides within the vertical limiting groove. The lower end of the vertical rod is threaded with a positioning bolt, and the nut of the positioning bolt abuts against the inner ring of the extrusion part. The side of the plate positioning opening used to press the plate is provided with an arc-shaped sliding groove, and an arc-shaped pad is slidably connected within the arc-shaped sliding groove.

[0012] As a preferred technical solution of this utility model, a positioning bearing is installed on the outside of the rotating shaft, the inner ring of the positioning bearing is fixedly connected to the rotating shaft, and the outer ring of the positioning bearing is in contact with the surface of the rotating part limiting part.

[0013] As a preferred technical solution of this utility model, an operating rod extending away from the rotation axis is fixedly connected to the vertical rod.

[0014] Beneficial effects: When this utility model is in operation, it only requires controlling the extruder to start extruding the plate from one side of the rotating limiter. The plate positioning block located behind the extruder can press one end of the already extruded plate against one side of the rotating limiter as the extruder moves, thus ensuring that one end of the plate will not lift up. Then, as the extruder continues to move and extrude the plate, it ensures the stability of the entire plate and guarantees the quality of the plate after extrusion. When the extrusion is completed, the extruder moves in the opposite direction, which can drive the plate positioning block to disengage from one side of the rotating limiter without affecting the removal of the plate. It is simple and practical. Attached Figure Description

Detailed Implementation

[0020] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0021] Example:

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides a tooling for manufacturing R-angles, including a fixed base 1, a rotating shaft 2 rotatably disposed at the center of the upper surface of the fixed base 1, and a rotating part limiting member 3 fixed to one side of the upper surface of the fixed base 1. It also includes a vertical rod 4 and an extrusion member 5 fixed to the lower end of the vertical rod 4. The vertical rod 4 is connected to the rotating shaft 2 via a first connecting rod 6 located above the rotating part limiting member 3. The above structure is the same as the prior art, both having an arc-shaped extrusion surface on the outside of the rotating part limiting member 3, which is extruded... Part 5 presses the plate 9 onto the arc-shaped extrusion surface to create the R-angle of the plate 9. Based on this, a limiting block 7 located on one side of the rotating limiting member 3 is fixed to the upper surface of the fixed base 1. A plate positioning block 8 is provided between the limiting block 7 and the rotating limiting member 3, allowing the plate positioning block 8 to move between them. The side of the plate positioning block 8 facing the rotating limiting member 3 has a plate positioning opening, used to press one end of the plate 9 tightly against one side of the rotating limiting member 3 through the plate positioning opening. Figure 1 As shown, when the plate positioning opening abuts against the rotating part limiting member 3, one side of the plate positioning opening can fit against one side of the rotating part limiting member 3, ensuring the stability of the plate positioning block 8. The other side of the plate positioning opening can press against one end of the already extruded plate 9, pressing it against the rotating part limiting member 3 by fitting against one end of the plate 9, preventing it from tilting up. The extrusion member 5 is located between the plate positioning block 8 and the rotating part limiting member 3, so that during preparation, it does not affect the placement of one end of the plate 9 on the arc-shaped extrusion surface of one side of the rotating part limiting member 3, and the extrusion member... 5 is connected to the plate positioning block 8 in a transmission manner. When the extruder 5 rotates from one side of the rotating limiter 3 to the other side, it can drive the plate positioning block 8 to press against one side of the rotating limiter 3. As the extruder 5 extrudes the plate 9, it can ensure the stability of the plate 9 behind the extruder 5. When the extruder 5 rotates towards the limiter block 7, it can drive the plate positioning block 8 to disengage from one side of the rotating limiter 3 and abut against the limiter block 7. This ensures that after the work is completed, the plate positioning block 8 can disengage from one side of the rotating limiter 3 without affecting the removal of the plate 9.

[0023] In operation, this invention only requires controlling the extruder 5 to start extruding the plate 9 from one side of the rotating limiter 3. The plate positioning block 8 located behind the extruder 5 can press one end of the extruded plate 9 against the rotating limiter 3 as the extruder 5 moves, thus ensuring that one end of the plate 9 will not lift up. Then, as the extruder 5 continues to move and extrude the plate 9, it ensures the stability of the entire plate 9 and guarantees the quality of the plate 9 after extrusion. When the extrusion is completed, the extruder 5 moves in the opposite direction, which can drive the plate positioning block 8 to disengage from the rotating limiter 3 without affecting the removal of the plate 9. It is simple and practical.

[0024] As a preferred embodiment of this example, it should be further explained that an arc-shaped rack 10 with the rotating shaft 2 as its central axis is provided outside the fixed base 1. One end of the arc-shaped rack 10 is fixedly connected to the vertical rod 4, and the other end of the arc-shaped rack 10 is connected to the rotating shaft 2 through the second connecting rod 11 to ensure the stability of the arc-shaped rack 10. An arc-shaped limiting hole is provided in the plate positioning block 8. A gear 12 is rotatably connected to one side of the arc-shaped limiting hole. The arc-shaped rack 10 passes through the arc-shaped limiting hole, and the inner side of the arc-shaped rack 10 meshes with the gear 12. The outer side of the arc-shaped rack 10 slides with the other side of the arc-shaped limiting hole. Preferably, the resistance of the gear 12 when rotating on one side of the arc-shaped limiting hole is relatively large (compared to...). If the central shaft of gear 12 is a damped rotating shaft (damped rotation occurs within the plate positioning block 8), then gear 12 can be moved by the arc-shaped rack 10. Gear 12 then moves the entire plate positioning block 8. Gear 12 only starts to rotate when the plate positioning block 8 abuts against the side of the rotating part limiter 3. The arc-shaped rack 10 then begins to slide along the arc-shaped limiter hole, without affecting the extruder 5 from continuing to extrude the plate 9. When the extruder 5 moves in the opposite direction, the effect is the same. The arc-shaped rack 10 moves gear 12, and gear 12 moves the entire plate positioning block 8 to abut against the limiter block 7. Then gear 12 starts to rotate, and the arc-shaped rack 10 begins to slide along the arc-shaped limiter hole, without affecting the reset of the extruder 5.

[0025] It should be noted that, in practice, a winding wheel can also be installed inside or on the surface of the plate positioning block 8. The winding wheel is mounted on the plate positioning block 8 via a coil spring, and a connecting line is wound on the winding wheel. The connecting line is connected to the vertical rod 4. In this way, when the vertical rod 4 moves to the other side of the rotating part limiting part 3, it can also drive the plate positioning block 8 to press the plate 9. When the vertical rod 4 is reset, the connecting line can also be automatically wound up under the action of the coil spring, thus providing different technical solutions for the transmission control of the plate positioning block 8.

[0026] As a preferred embodiment of this example, it should be further explained that the plate positioning block 8 includes an upper positioning block and a lower positioning block connected by a first bolt. An arc-shaped limiting hole is located between the upper positioning block and the lower positioning block. A gear receiving groove is provided on one side of the arc-shaped limiting hole. The gear 12 is rotatably connected in the gear receiving groove, which facilitates the assembly of the plate positioning block 8.

[0027] As a preferred embodiment of this example, it should be further explained that the upper surface of the fixed base 1 is provided with an arc-shaped slide rail located between the limiting block 7 and the rotating part limiting part 3, and the lower end of the plate positioning block 8 is provided with an arc-shaped slide groove. The arc-shaped slide groove slides in cooperation with the arc-shaped slide rail, which makes the plate positioning block 8 more stable. The inner wall of the arc-shaped slide groove is preferably provided with ball bearings. By using the ball bearings to cooperate with the arc-shaped slide rail, the friction can be reduced.

[0028] As a preferred embodiment of this example, it should be further explained that the extrusion member 5 is a ball bearing, and the inner ring of the extrusion member 5 is connected to the lower end of the vertical rod 4. In this way, when the extrusion member 5 extrudes the plate 9, the outer ring of the ball bearing is rolled on the surface of the plate 9, which can reduce the friction when the extrusion member 5 moves, making the operation of this R-angle manufacturing tool easier.

[0029] As a preferred embodiment of this invention, it should be further explained that the lower end of the vertical rod 4 is provided with a vertical limiting groove, and the inner ring of the extrusion piece 5 is provided with a vertical limiting block. The vertical limiting block slides within the vertical limiting groove. The lower end of the vertical rod 4 is threadedly connected with a positioning bolt. The nut of the positioning bolt abuts against the inner ring of the extrusion piece 5 and presses the vertical limiting block against the vertical limiting groove, ensuring the stability of the extrusion piece 5. This allows for the replacement of the extrusion piece 5, thereby adjusting the distance between the extrusion piece 5 and the rotating part limiting part 3, facilitating adaptive adjustments for different models of plate pieces 9. The side of the plate positioning port used to press the plate piece 9 is provided with an arc-shaped sliding groove, and an arc-shaped pad is slidably connected within the arc-shaped sliding groove. This allows the arc-shaped pad to press the plate piece 9 when pressing it at the plate positioning port, also facilitating adaptive adjustments for different models of plate pieces 9.

[0030] As a preferred embodiment of this invention, it should be further explained that a positioning bearing 13 is installed on the outside of the rotating shaft 2. The inner ring of the positioning bearing 13 is fixedly connected to the rotating shaft 2, and the outer ring of the positioning bearing 13 is in contact with the rotating part limiting member 3. This can more quickly and accurately ensure that the arc-shaped extrusion surface of the rotating part limiting member 3 is coaxially set with the rotating shaft 2.

[0031] As a preferred embodiment of this invention, it should be further explained that an operating rod 14 extending away from the rotating shaft 2 is fixedly connected to the vertical rod 4, which facilitates the operation of the vertical rod 4 to rotate around the rotating shaft 2, thereby realizing the extrusion molding of the plate 9.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
