Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to a tooling and fixture for machining precision mechanical parts that is easy to adjust. Background Technology

[0002] Tooling fixtures are tools and devices used in industrial production to assist production, ensure product quality, and improve production efficiency. They are widely used in manufacturing for the rapid positioning of parts before machining. The bench vise, as a major tooling fixture in the machining of precision mechanical parts, needs to clamp both sides of the workpiece during use. However, when the corresponding inclined surfaces need to be ground during the machining process, in order to ensure operational accuracy and convenience, the machining surface needs to be rotated to a horizontal position. At this time, the bench vise needs to be operated again to re-clamp the workpiece. This process requires multiple parts to be picked up and clamped, increasing the number of operation steps, consuming too much machining time, and reducing machining efficiency.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a tooling fixture for machining precision mechanical parts that is easy to adjust.

[0024] This utility model provides, for example Figure 1-4 The tooling fixture for machining precision mechanical parts, which is easy to adjust, includes a vise base 1 and a sliding seat 2 that is slidably sleeved on the upper outer side of the vise base 1. A first support shaft 3 and a second support shaft 4 are respectively rotatably inserted through the upper side of the vise base 1 and the sliding seat 2. A clamping plate 5 is fixedly installed at the close side of the first support shaft 3 and the second support shaft 4. Multiple anti-slip grooves 16 are opened at intervals on the close side of the two clamping plates 5. A damping sleeve 15 is rotatably sleeved on the shaft wall of the second support shaft 4. The damping sleeve 15 is fixedly inserted inside the sliding seat 2. A drive screw 6 is rotatably inserted through the lower inner end of the vise base 1. The drive screw 6 is threaded inside the sliding seat 2. An operating handle 7 is fixedly installed at the end of the drive screw 6. A corrugated telescopic tube 17 is fixedly installed between the lower inner wall of the vise base 1 and the sliding seat 2. The corrugated telescopic tube 17 is sleeved on the outside of the drive screw 6.

[0025] The top of the vise base 1 is provided with a rotating groove 18, and the shaft wall of the first support shaft 3 is fixedly fitted with a rotating plate 8, which is located in the rotating groove 18.

[0026] Before precision machining of the part, the part is placed between two clamping plates 5. Then, the operating handle 7 is pushed, causing the operating handle 7 to drive the drive screw 6 to rotate. At this time, the sliding seat 2 slides along the vise base 1, causing the two clamping plates 5 to move closer to each other and stably clamp the workpiece. The workpiece can be stably clamped and processed. When it is necessary to process the inclined surface of the workpiece, the rotating plate 8 can be pushed, causing the rotating plate 8 to drive the first support shaft 3 to rotate. At this time, with the rotation cooperation of the second support shaft 14, the part can be rotated, making it easier to rotate the inclined surface of the part to a horizontal position, thus improving the convenience of processing.

[0027] In order to determine the position of the rotating plate 8 after the rotating plate 8 drives the part to rotate, such as Figure 1-3As shown, the outer wall of the rotating plate 8 is provided with multiple positioning grooves 9 arranged symmetrically around it. The top of the inner wall of each positioning groove 9 is engraved with angle scale lines 14. The positioning groove 9 is provided with a quick-insertion positioning mechanism, which includes a clamping plate 10. The upper end of the vise base 1 is fixedly provided with two symmetrically arranged mounting plates 11. The two mounting plates 11 are located on both sides of the clamping plate 10, and a crossbar 12 is rotatably passed through them. The crossbar 12 is fixedly located inside the clamping plate 10. Both ends of the crossbar 12 are fitted with torsion springs 13, and the two ends of the torsion springs 13 are fixedly connected to the mounting plate 11 and the crossbar 12, respectively.

[0028] Before rotating the part, one end of the clamping plate 10 can be pressed longitudinally. At this time, with the rotational cooperation of the crossbar 12 and the mounting plate 11, the clamping plate 10 starts to rotate under the support of the crossbar 12 and moves away from the positioning groove 9. At this time, the torsion spring 13 is twisted, and then the rotating plate 8 can be rotated. The rotation angle of the part is determined under the indication of multiple angle scale lines 14. When the rotation is finished, the clamping plate 10 is released. Under the torque recovery of the torsion spring 13, the clamping plate 10 can drive the crossbar 12 to rotate back to its original position and continue to be inserted into the positioning groove 9, thereby completing the position fixation of the rotating plate 8 and the part, ensuring the stability of subsequent part processing.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
