Description

Technical Field

[0001] The utility model relates to the technical field of hole group chamfering, in particular to a self-centering twelve-hole group chamfering. Background Art

[0002] Twelve-hole group chamfering is a processing technology that can chamfer twelve positions of the workpiece at the same time through a specially designed tool with twelve chamfering blades. This process is suitable for situations where a large amount of chamfering is required, which can improve processing efficiency and reduce production costs. Twelve-hole group chamfering is usually used in metal processing, plastic processing, glass processing and other fields, and is suitable for workpieces of different shapes such as outer circle chamfering, inner hole chamfering, and plane chamfering. This process requires the chamfering tool to have high precision, high wear resistance and stability to ensure the quality and efficiency of chamfering. When performing twelve-hole group chamfering, the following points should be noted: 1. Workpiece fixation: Ensure that the workpiece is firmly fixed during the processing to avoid vibration and displacement, which affects the accuracy of chamfering. 2. Tool selection: Select a suitable twelve-hole group chamfering tool, and determine the tool's blade material, blade angle and other parameters according to the workpiece material and processing requirements. 3. Processing parameters: Set appropriate processing parameters, including cutting speed, feed speed, cutting depth, etc., to ensure the stability and efficiency of chamfering. 4. Check the quality: After the processing is completed, check the quality and size of the chamfer in time to ensure that it meets the requirements, and make adjustments if necessary. Through the above precautions, the chamfering of the twelve-hole group can be effectively realized, the processing efficiency can be improved, the processing quality can be optimized, and the chamfering processing requirements of different workpieces can be met. In actual operation, it is necessary to flexibly adjust and optimize the processing process according to the specific situation to ensure that the processing effect meets the expected requirements.

The positioning process is relatively troublesome and the work efficiency is low. In order to improve the work efficiency, a self-centering twelve-hole group chamfering device is urgently needed.

This self-centering twelve-hole group chamfering has a self-centering effect through the settings of a PLC controller, an electric rotating table, a third slider, an electric telescopic rod, a positioning pin, a positioning hole, a trigger block and a micro switch. When in use, the workpiece to be chamfered is installed on the clamping seat. When installing, first place the workpiece between two clamping blocks, and drive the bidirectional screw rod to rotate through the first servo motor, so that the two first sliders threadedly connected on the surface of the bidirectional screw rod move inward synchronously in the first slide groove. When the first slider moves, it drives the clamping block to move together, and the workpiece is clamped in the V by two clamping blocks close to each other. The workpiece is fixed in a position concentric with the clamping seat by setting the V-groove, and then the distance from the center of the locating hole on the surface of the workpiece to the outer circle is obtained according to the drawing of the workpiece, and then the distance from the locating hole to the upper surface of the worktable is obtained according to the distance from the electric rotating table to the upper surface of the worktable, and then the telescopic end of the electric telescopic rod is controlled to extend outward to move the locating pin on the surface of the fixed block to the same height as the locating hole. At this time, the third servo motor is controlled to work, and the third lead screw is driven to rotate by the third servo motor, so that the third slider threaded on the surface of the third lead screw moves to the left in the third slide groove. At this time, the positions of the locating pin and the locating hole are not Without comparison, the left end face of the locating pin contacts the surface of the workpiece. As the third slider moves to the left, the locating pin is squeezed into the groove, causing the trigger block to contact the microswitch. At this time, the microswitch is in the detection state, and then the electric rotary table is controlled to work, and the clamping seat is driven to rotate as a whole through the electric rotary table. When the locating hole rotates to the lowest point, the locating pin is completely compared with the locating hole. Under the action of the spring, the locating pin is ejected outward, so that the locating pin enters the locating hole. At this time, the trigger block is separated from the microswitch, and the microswitch contacts the detection state and feeds back the information to the PLC controller. At this time, the positioning of the workpiece is completed and the control is completed. The third slider moves to the right in the third slide groove, and at the same time, the telescopic end of the electric telescopic rod is contracted to complete the reset. Finally, the second servo motor drives the second lead screw to rotate, so that the second slider threaded on the surface of the second lead screw moves to the left in the second slide groove. The second slider drives the second mounting seat, the drill group seat, the drive motor and the chamfering drill to approach to the left, so that the chamfering drill moves to the position of the through hole. The chamfering drill is driven to rotate by the drive motor. As the second mounting seat moves to the left, the chamfering of the through hole is completed. The control process of the device is controlled by a PLC controller, which plays a role of rapid centering and achieves the purpose of improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
