Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, and in particular to a component positioning tooling. Background Technology

[0002] Component positioning fixtures are important equipment in industrial production that assist in the processing and assembly of parts. They are widely used in machinery manufacturing, automotive parts production, and electronic component assembly. Their core design revolves around precise positioning and convenient operation to adapt to the processing needs of parts of different specifications. In actual use, the fixture can quickly fix the parts to be processed or assembled in the preset position through preset positioning pins, clamping structures, and limit blocks, ensuring that the parts maintain a stable posture during drilling, welding, and splicing processes, and avoiding the impact of positional deviation on processing accuracy.

[0003] Meanwhile, the structure of the tooling can be adapted to the shape and size of the parts, thus being compatible with various specifications of parts and reducing the frequency of equipment replacement. In terms of operation, workers only need to complete the clamping and positioning of parts in a simple process. In addition, traditional positioning tooling usually uses mechanical clamping and hydraulic drive. Mechanical clamps rely on manual adjustment, which is difficult to meet the needs of high-precision parts. At the same time, positioning tooling lacks real-time status monitoring, and clamping failure can easily lead to workpiece displacement and equipment collision damage, affecting the efficiency of equipment use. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see the appendix Figure 1 - Appendix Figure 2An embodiment of this utility model is provided: a component positioning fixture, including a mounting plate 1, a guide shaft 2 is provided on the top left and right sides of the mounting plate 1, a support plate 3 is fixedly connected to the top of the guide shaft 2, a positioning wheel 4 is provided on the top left and right sides of the support plate 3, a clamping arm 5 is provided on the bottom left and right sides of the support plate 3, a pneumatic gripper 6 is provided in the top middle of the mounting plate 1, and a magnetic sensor 7 is provided on the rear side of the pneumatic gripper 6.

[0022] Specifically, the top of the guide shaft 2 is fixedly connected to the support plate 3 through a reliable connection method. The support plate 3 is in a horizontal state, providing a stable installation platform. Positioning wheels 4 are respectively set on the top left and right sides of the support plate 3. The positioning wheels 4 can roll flexibly to ensure the accuracy of the position of the entire device during operation. Clamping arms 5 are respectively set on the bottom left and right sides of the support plate 3. The clamping arms 5 can open and close according to the control signal. At the top center of the mounting plate 1, a pneumatic gripper 6 is set. The pneumatic gripper 6 has a strong gripping ability and can quickly and accurately grasp and place items. A magnetic sensor 7 is also set on the rear side of the pneumatic gripper 6. The magnetic sensor 7 can sense the working status of the pneumatic gripper 6 and the changes in the surrounding magnetic environment in real time, so as to accurately control and adjust the entire device.

[0023] Please see the appendix Figure 1 - Appendix Figure 2 The top of the magnetic sensor 7 is rotatably connected to a baffle 10, the top and rear sides of the support plate 3 are fixedly connected to elongated blocks 9, the bottom of the mounting plate 1 is fixedly connected to support legs 8, and the bottoms of multiple baffles 10 are fixedly connected to the same horizontal height.

[0024] Specifically, the baffle 10 can be flexibly rotated to adjust its angle according to actual working needs, so as to better perform functions such as protection, blocking and triggering specific actions. The outrigger 8 firmly supports the entire mounting plate 1 and the many components it carries on top of it, keeping the bottom of the baffle 10 at the same level, which can ensure the coordination and consistency of the actions of each part of the device during operation.

[0025] Working principle: By placing the workpiece between the positioning wheel 4 and the support plate 3, the pneumatic gripper 6 closes under pneumatic drive, driving the two sets of clamping arms 5 to move synchronously. The positioning wheel 4 flexibly clamps the workpiece, while the guide shaft 2 ensures the accuracy of linear motion. At this time, the magnetic sensor 7 monitors the clamping position signal in real time. After high-precision positioning is completed, the workpiece enters the predetermined process. The use of four sets of high-precision guide shafts 2 results in higher accuracy than traditional slide rails. A flexible clamping device is used, where the pneumatic gripper 6 drives the clamping arms 5 with adjustable clamping force. The end uses ultra-high molecular weight polyethylene positioning wheels 4, reducing manual intervention and eliminating the need for frequent replacements. The low coefficient of friction prevents scratching the workpiece. The magnetic position sensor 7 provides real-time feedback signals to prevent under-clamping and overload. It can be connected to a PLC device to realize automated production interlocking control.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
