Description

Technical Field

[0001] This utility model relates to the field of machining tooling technology, and in particular to a tooling for batch machining hexagonal nut locking holes. Background Technology

[0002] In the field of mechanical manufacturing, hexagonal nuts, as a basic and important standard component, are widely used in the connection and fastening of various equipment and components. With the acceleration of industrialization, the demand for hexagonal nuts is increasing, especially placing higher demands on the processing efficiency and precision of their locking holes. In existing methods of machining hexagonal nut locking holes, bolts are used to limit their movement to prevent them from falling out and to ensure processing stability. This results in the nut being tightly stuck inside the hole groove due to the bolt's tightening force. When the locking hole is completed and the nut needs to be removed, it becomes inconvenient, thus reducing work efficiency. Therefore, this utility model proposes a tooling for batch processing hexagonal nut locking holes. Utility Model Content

[0003] The purpose of this utility model is to address the problem in the background art where, during the processing of hexagonal nut locking holes, bolts are needed to limit the nuts to prevent them from falling off and to ensure processing stability. This results in the nuts being tightly stuck inside the slot due to the tightening force of the bolts during placement. When the locking hole processing is completed and the nuts need to be removed, it is inconvenient to remove the nuts, thus reducing work efficiency. The present invention proposes a tooling for batch processing hexagonal nut locking holes.

[0004] The technical solution of this utility model is as follows: a tooling for batch processing hexagonal nut locking holes, comprising: a fixing block, wherein multiple placement slots are respectively opened on both sides of the fixing block, and grooves are respectively opened inside the placement slots; a processing nut for processing is disposed inside the placement slot, and a locking screw is threadedly sleeved on the processing nut; an internally threaded cylinder is fixedly disposed inside the groove, the internally threaded cylinder is threadedly sleeved with the locking screw, and an ejection component for pushing the processing nut is sleeved on the outer wall of the internally threaded cylinder.

[0005] Optionally, the ejection assembly includes an ejection spring sleeved on the outer wall of the internal threaded cylinder. One end of the ejection spring is fixedly connected to the inner wall of the groove, and the other end of the ejection spring is fixedly connected to an ejection ring, which is movably sleeved with the internal threaded cylinder.

[0006] Optionally, the inner wall of the groove is provided with a plurality of air holes.

[0007] Optionally, the fixing block is configured with a "T" shaped structure.

[0008] Optionally, the diameter of the pores is 2mm-4mm.

[0009] Optionally, the outer wall of the locking screw is provided with anti-slip texture.

[0010] In summary, this application includes at least one of the following beneficial technical effects:

[0011] This utility model, by setting a structure in which the internal threaded cylinder and the locking screw are threadedly connected, avoids the situation where the nut is stuck in the hole groove due to the bolt tightening force. At the same time, the ejection spring and ejection ring in the ejection assembly cooperate to automatically eject the processed nut from the placement groove after the locking hole is processed, which greatly simplifies the nut picking and putting operation, significantly improves the nut loading and unloading efficiency, and optimizes the overall processing flow.

[0012] Furthermore, this utility model achieves batch clamping and processing of hexagonal nuts through the design of multiple placement slots. With the addition of air holes, it can effectively discharge the debris and heat generated during the processing, reduce the impact of debris on processing accuracy and the workpiece deformation caused by heat, prevent the processed nuts from getting stuck inside the placement slots, and ensure stable processing quality.

[0027] Example

[0028] like Figures 1 to 5 As shown, the present invention proposes a tooling for batch processing of hexagonal nut locking holes, comprising: a fixing block 1, the fixing block 1 having a "T" shaped structure, which facilitates clamping the fixing block 1 with the machine tool, thereby preventing displacement during processing and ensuring processing stability; multiple placement grooves 2 are respectively opened on both sides of the fixing block 1, and the placement grooves 2 have a hexagonal structure, which can stably limit the processing of the nut 4 and prevent displacement during processing; grooves 3 are respectively opened inside the placement grooves 2, and the grooves 3 are connected to the placement grooves 2.

[0029] Furthermore, the interior of the placement groove 2 is provided with a machining nut 4 for machining. The machining nut 4 is a hexagonal nut that can be matched with the placement groove 2 to stabilize and limit its position. A locking screw 5 is threaded onto the machining nut 4. The outer wall of the locking screw 5 is provided with anti-slip texture 9, which makes it easy to manually rotate the locking screw 5 to stabilize and limit the machining nut 4 inside the placement groove 2.

[0030] Secondly, the internally threaded cylinder 6 is fixedly installed inside the groove 3. The internally threaded cylinder 6 is threadedly connected to the locking screw 5, which enables the locking screw 5 to stably limit the movement of the machined nut 4.

[0031] like Figure 2 As shown, the outer wall of the internal threaded cylinder 6 is fitted with an ejector assembly 7 for pushing the processed nut 4. The ejector assembly 7 includes an ejector spring 71 fitted on the outer wall of the internal threaded cylinder 6. One end of the ejector spring 71 is fixedly connected to the inner wall of the groove 3, and the other end of the ejector spring 71 is fixedly connected to an ejector ring 72. The ejector spring 71 can push the ejector ring 72 to push the processed nut 4 out of the placement groove 2 for easy removal. The ejector ring 72 is movably fitted with the internal threaded cylinder 6, which can stably guide the ejector ring 72, thereby ensuring the stability of pushing out the processed nut 4.

[0032] Furthermore, the inner wall of the groove 3 is provided with multiple air holes 8, the diameter of which is 2mm-4mm. This effectively discharges the debris and heat generated during the processing, reduces the impact of debris on processing accuracy and the workpiece deformation caused by heat, and prevents the processing nut from getting stuck inside the placement groove.

[0033] In this embodiment, multiple processed nuts 4 are respectively placed in the placement grooves 2 on both sides of the fixing block 1, so that the processed nuts 4 are adapted to the placement grooves 2.

[0034] The locking screw 5 is threaded through the machining nut 4 and threaded into the internally threaded cylinder 6 fixed in the groove 3. The locking screw 5 is then tightened to fix the machining nut 4. The fixture is then fixed to the machine tool in a suitable manner using the "T"-shaped fixing block 1.

[0035] Start the machine tool and process the locking holes of multiple machining nuts 4 in the placement slot 2.

[0036] After processing, the locking screw 5 is rotated in the opposite direction to separate it from the internal threaded cylinder 6. The ejector spring 71 pushes the ejector ring 72 to eject the processed nut 4 from the placement groove 2. The air holes 8 on the inner wall of the groove 3 help balance the air pressure to ensure smooth ejection.

[0037] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
