Detailed Implementation
[0022] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.
[0023] Please see Figures 1 to 5This application provides a bidirectional clamping device for tooling fixtures, including a base plate 1. A support 2 and a positioning block 5 are fixedly connected to the top surface of the base plate 1. Both the support 2 and the positioning block 5 are fixed to the base plate 1 by fixing screws 3 and washers 4. A flipping pressure plate 7 is rotatably connected to the support 2. The positioning block 5 has a workpiece placement area 51 and a vertically arranged blocking part 52. During positioning, the workpiece 6 is placed in the workpiece placement area 51, with one side surface abutting against the blocking part 52. The pressing surface of the flipping pressure plate 7 presses against the surface of the workpiece 6, thereby limiting the vertical movement of the workpiece 6. The positioning block 5 and the flipping pressure plate 7 cooperate to position the workpiece 6 in both the horizontal and vertical directions.
[0024] Specifically, the support 2 has two parallel pillars, a flipping pressure plate 7 is installed between the two pillars, and a rotating shaft 8 connects the flipping pressure plate 7 to the support 2. The flipping pressure plate 7 rotates relative to the axis of the rotating shaft 8, thereby flipping the pressure plate 7. The rotating shaft 8 and the support 2 are interference-fitted to improve the firmness of their connection.
[0025] Furthermore, the rotating shaft 8 and the light hole on the flipping pressure plate 7 are in clearance fit, allowing the flipping pressure plate 7 to rotate freely clockwise and counterclockwise around the rotating shaft 8. To ensure that the flipping pressure plate 8 can rotate freely around the rotating shaft 8, there is a gap between the flipping pressure plate 7 and the two pillars of the support 2. Figure 2 As shown, the workpiece 6 needs to be positioned by the positioning block 5, and the workpiece 6 is clamped vertically and horizontally by the flipping pressure plate 7 and the clamping screw 9. The operation is simple and the clamping effect is stable.
[0026] The flipping pressure plate 7 includes a vertical plate 71 and an inclined plate 72 connected thereto. The bottom surface of the inclined plate 72 has a convex arc surface that contacts the top surface of the workpiece 6. A threaded hole 711 is provided at a lower position on the vertical plate 71. A clamping screw 9 passes through the threaded hole 711 and points towards the workpiece 6, applying a horizontal clamping force to the workpiece 6. In the unused state, the bottom surface of the vertical plate 71 forms an angle with the horizontal plane, and the inclined plate 72 is tilted towards the positioning block 5. In use, the inclined plate 72 rotates upward, placing the workpiece 6 under it, so that the convex arc surface contacts the top surface of the workpiece 6. The flipping pressure plate 7 is adjusted so that the bottom surface of the vertical plate 71 coincides with the horizontal plane. The clamping screw 9 passes through the threaded hole 711 and horizontally clamps the workpiece 6, which can both clamp the workpiece 6 and limit the flipping pressure plate 7 to prevent it from rotating and affecting the positioning effect.
[0027] A lever 10 is provided at one end of the clamping screw 9 to facilitate rotation of the clamping screw 9.
[0028] The working principle of this utility model is as follows:
[0029] First, the workpiece 6 is positioned by the positioning block 5. The flipping pressure plate 7 rotates around the rotating shaft 8, and the convex arc surface of the flipping pressure plate 7 presses against the upper surface of the workpiece. Then, the clamping screw 9 is inserted into the threaded hole 711 opened at the lower position of the flipping pressure plate 7. The clamping screw 9 is turned by the lever 10, thereby generating a horizontal clamping force to press the workpiece against the blocking part 52 of the positioning block 5. The workpiece is subjected to horizontal friction and vertical clamping force. The vertical clamping force presses the workpiece against the horizontal positioning surface. After the workpiece is processed, the clamping screw 9 is turned in the opposite direction to release the horizontal clamping force and disengage from the flipping pressure plate 7. The flipping pressure plate 7 rotates in the opposite direction around the rotating shaft 8, away from the workpiece, and the vertical clamping force on the workpiece is removed, and the workpiece is taken out.
[0030] The above are preferred embodiments of the present utility model. Those skilled in the art can make various changes or improvements based on this. Without departing from the overall concept of the present utility model, these changes or improvements should all fall within the scope of protection claimed by the present utility model.
