Description

Technical Field

[0001] This utility model belongs to the field of mechanical tapping technology, specifically relating to a workpiece tapping error prevention device. Background Technology

[0002] In the field of mechanical manufacturing, threading is a common process. Currently, dedicated tapping machines for workpieces typically consist of a rocker arm, a positioning fixture, and a servo tapping head. The worker places the workpiece on the positioning fixture and clamps it, then uses the servo tapping head fixed to the rocker arm to tap the holes sequentially. However, this type of workpiece tapping process has the following drawbacks: 1. High worker dependence: It relies entirely on the operator's attention and experience to judge the integrity of the process. When there are many holes or the hole distribution is complex, it is very easy to miss holes. 2. Significant quality risks: If a workpiece with unfinished tapping flows into the next process, it will lead to serious quality problems; 3. Inspection lag: After the workpiece is tapped, it is usually inspected manually by visual inspection, which cannot achieve real-time inspection during the processing. Therefore, we propose a workpiece tapping error prevention device. Utility Model Content

[0015] Please see Figures 1-4 The workpiece tapping error prevention device provided by this utility model includes: Processing table 1, on which a radial tapping machine 2 is installed; The positioning support assembly 3 includes two symmetrically arranged on the machining table 1, with the workpiece 4 to be tapped positioned between the two positioning support assemblies 3.

The positioning support assembly 3 also includes three limiting blocks 304, which are alternately arranged on the machining table 1 on both sides of the workpiece 4 to be tapped. Two pneumatic clamping assemblies 5 are symmetrically arranged on the processing table 1 to clamp the workpiece 4 to be tapped placed between two positioning support assemblies 3. Each pneumatic clamping assembly 5 includes a clamping table 501, a clamping cylinder 502, a bracket 503, a movable rod 504, and a clamping block 505. The clamping table 501 is positioned on the processing table 1 corresponding to the bottom of the workpiece 4 to be tapped. The clamping cylinder 502 is positioned on the processing table 1 behind the clamping table 501. The bracket 503 is positioned on the clamping table 501 near one end of the clamping cylinder 502. The output end of the clamping cylinder 502 is movably connected to one end of the movable rod 504. The movable rod 504 and... The bracket 503 is movably connected, and the clamping block 505 is set at the other end of the movable rod 504 corresponding to the position of the workpiece 4 to be tapped. The pneumatic clamping assembly 5 also includes an electric push button switch 506 and an electromagnetic pneumatic valve 507. The electromagnetic pneumatic valve 507 is a two-position five-way electromagnetic pneumatic valve. Both the electric push button switch 506 and the electromagnetic pneumatic valve 507 are set on the processing table 1. The electric push button switch 506 and the electromagnetic pneumatic valve 507 are connected. The electromagnetic pneumatic valve 507 is connected to the clamping cylinder 502, and the electromagnetic pneumatic valve 507 is connected to an external air supply system (the air supply system is existing technology and is used to supply air to the clamping cylinder 502. It is well known to those skilled in the art and will not be described in detail here). This utility model is provided with a positioning support assembly 3 and a pneumatic clamping assembly 5. In use, the workpiece 4 to be tapped is placed between the positioning blocks 302 on the two support blocks 301, and the two sides of the workpiece 4 to be tapped are limited and fixed by the three limit blocks 304. Then, the electric button switch 506 is pressed, the electromagnetic pneumatic valve 507 is started, and air is supplied to the clamping cylinder 502 through the external air supply system, so that the clamping cylinder 502 is extended. At this time, the movable rod 504 rotates on the bracket 503, so that the clamping block 505 at the other end of the movable rod 504 moves toward the workpiece 4 to be tapped, thereby clamping the workpiece 4 to be tapped. This can effectively fix and clamp the workpiece 4 to be tapped, avoid the workpiece 4 to be tapped from shifting during the tapping process, and ensure the accuracy and stability of the tapping process of the workpiece 4 to be tapped. Error-proofing detection component 6 is installed on the processing table 1 to detect the tapping status of the workpiece 4 to be tapped and to control the clamping and loosening of the pneumatic clamping component 5. Error-proofing detection component 6 includes detection sensor 601, indicator light 602 and electrical control box 603. Detection sensor 601 is installed on support block 301 and extends into threaded hole 303. Indicator light 602 and electrical control box 603 are both installed on processing table 1. Detection sensor 601, indicator light 602, electrical control box 603, electromagnetic pneumatic valve 507 and electric push button switch 506 are connected to each other. Detection sensor 601 is an NPN type proximity switch. This utility model is equipped with a fault-prevention detection component 6. During the tapping process of the workpiece 4, the tap of the rocker arm tapping machine 2 drills into the threaded hole 303 on the support block 301. At this time, the detection sensor 601 will sense the tap and transmit the signal to the electrical control box 603. The electrical control box 603 controls the indicator light 602 corresponding to the detection sensor 601 in the threaded hole 303 to light up. After all the indicator lights 602 are lit, it means that the tapping of the workpiece 4 is completed. Then, the electrical button switch 506 is pressed. This causes the clamping cylinder 502 to retract, causing the clamping block 505 to release the workpiece 4 to be tapped, and the workpiece 4 to be tapped is removed. At this time, the control indicator light 602 of the electrical control box 603 turns off, and the tapping process is completed. It can detect the processing status of each hole in real time, accurately identify the missed holes, and prevent the unfinished workpiece 4 to be tapped from being removed through an electrical locking mechanism. It also reduces the workload of operators by providing intuitive indicator light status indications, and is compatible with existing tapping machine equipment with low modification costs. It is suitable for various tapping processing environments.

[0016] like Figure 5The diagram shown is a circuit schematic of this utility model, which is well known to those skilled in the art and will not be described in detail here (the connection and control between the detection sensor 601, indicator light 602, electrical control box 603, electromagnetic pneumatic valve 507 and electrical push button switch 506 are existing technologies, and their control programs are also existing technologies, which are well known to those skilled in the art and will not be described in detail here).

[0017] In summary, the method of using the workpiece tapping error prevention device provided in this embodiment is as follows: During use, the workpiece 4 to be tapped is placed between the positioning blocks 302 on the two support blocks 301, and the workpiece 4 is fixed and limited on both sides by the three limiting blocks 304. Then, the electrical button switch 506 is pressed, the electromagnetic pneumatic valve 507 is activated, and air is supplied to the clamping cylinder 502 through the external air supply system, causing the clamping cylinder 502 to extend. At this time, the movable rod 504 rotates on the bracket 503, causing the clamping block 505 at the other end of the movable rod 504 to move towards the workpiece 4 to be tapped, thereby clamping the workpiece 4. During the tapping process of the workpiece 4... When the tap bit of the radial arm tapping machine 2 drills into the threaded hole 303 on the support block 301, the detection sensor 601 will sense the tap bit and transmit the signal to the electrical control box 603. The electrical control box 603 will control the indicator light 602 corresponding to the detection sensor 601 in the threaded hole 303 to light up. After all the indicator lights 602 are lit up, it means that the tapping of the workpiece 4 is completed. Then, press the electrical button switch 506 to retract the clamping cylinder 502, causing the clamping block 505 to release the workpiece 4 to be tapped and take out the workpiece 4. At this time, the electrical control box 603 controls the indicator light 602 to turn off, and the tapping is completed.
