Contents of the invention

The purpose of the utility model is to provide an automatic feeding mechanism for small workpieces. After adopting the automatic feeding system, the production efficiency and safety are greatly improved.

The utility model is achieved through the following technical solutions:

An automatic feeding mechanism for small workpieces, including a base, a sliding frame, and a claw frame; the sliding frame is arranged on the base with a horizontal propulsion cylinder between them, and the sliding frame can be horizontally moved on the base under the action of the horizontal propelling cylinder. Sliding, the claw frame is arranged on the sliding frame and a vertical propulsion cylinder is arranged therebetween, the claw frame can slide vertically on the sliding frame under the action of the vertical propulsion cylinder, and a feeding claw is provided on the claw frame.

After the jaws of the utility model clamp the small workpieces, they can move horizontally and vertically in order to accurately place the small workpieces in the chuck of the processing machine tool. The specific process is: after the jaws clamp the small workpieces , push the cylinder horizontally to push the sliding frame horizontally, push the cylinder vertically and then push the claw frame vertically downward, and retract the cylinder horizontally so that the small workpiece can be put into the chuck and be clamped by the chuck for processing, and the claw frame will return to the next step It can be seen from this that the utility model can accurately send small-scale work to the chuck for processing through horizontal and vertical movement, avoiding inaccuracy and potential safety hazards during manual operation.

Further structure of the present utility model is:

A guide device is provided between the base and the sliding frame, and between the sliding frame and the claw frame. When the jaws feed small workpieces to the chuck, the workpiece needs to be pressed into the chuck to ensure that the workpiece is in place. At the same time, during the multiple operations of the mechanism, wear and deformation will occur, which will affect the accuracy of the feeding position. Set With the guide device, the accuracy of the horizontal sliding of the sliding frame and the vertical sliding of the claw frame can be guaranteed, and deviations can be avoided. On the device, it can be seen that after the guide device is provided, the strength of the mechanism is improved.

The guide device is a slide rail and a slide block matched with the slide rail. During the working process, the slider slides on the slide rail, and the slide rail guides the slider to prevent the slider from shifting, or the guide device is a guide hole and is arranged in the guide hole and can slide relative to it guide rod. During the working process, the guide rod slides in the guide hole. After the guide device is installed, the accuracy of the work feeding and the strength of the mechanism are improved. In order to further improve the guiding effect, there are at least two guide devices. Two guiding devices are arranged in parallel.

A jacking cylinder is arranged on the claw frame, and a plug is arranged on the jacking cylinder, and the plug is aligned with the clamping position of the feeding claw. When the jaws send the small work to the side of the chuck, the small workpiece cannot be accurately sent into the chuck. At this time, it is necessary to open the jacking cylinder and push the small workpiece into the chuck through the jack.

The base is provided with a horizontal limiter capable of limiting the sliding frame, and the sliding frame is provided with a vertical limiter capable of limiting the claw frame. When the sliding frame slides horizontally, the horizontal limiter acts as a limiter for the sliding frame; when the claw frame slides vertically, the vertical limiter acts as a vertical limiter for the claw frame, preventing the sliding frame, The claw frame collides during the sliding process to damage the mechanism, and also restricts the accurate positioning of the mechanism during the sliding process.

The horizontal limiting member is threaded on the base, or the vertical limiting member is threaded on the sliding frame. The horizontal limit piece or the vertical limit piece is connected by thread, and the position of the limit piece may be adjusted by rotating the adjusting screw, thereby adjusting the limit position of the sliding frame or the claw frame.

A discharge claw is also connected to the base. After the small workpiece is processed on the machine tool, the small workpiece is unloaded from the chuck of the machine tool through the discharge jaw.

The feeding system also includes a discharge propelling cylinder and a rotary cylinder, and the discharge claw is connected to the base through the discharge propelling cylinder and the rotary cylinder. When unloading, the unloading propulsion cylinder moves to unload the workpiece from the chuck of the machine tool, the rotary cylinder rotates, the unloading jaws swing downward, and the next job enters the chuck of the machine tool for processing. After the processing is completed, the rotary cylinder swings upward , the jaws clamp the workpiece, and the unloading push cylinder moves to unload the workpiece from the chuck of the machine tool, and so on.

Detailed ways

As shown in Figures 1 and 2, a small workpiece automatic feeding mechanism includes a base 1, a sliding frame 2, and a claw frame 4; The frame 2 can slide horizontally on the base 1 under the action of the horizontal propelling cylinder 3. The claw frame 4 is arranged on the sliding frame 2 and a vertical propelling cylinder 5 is arranged therebetween. The claw frame 4 plays a role in the vertical propelling cylinder 5 The bottom can slide vertically on the sliding frame 2, and the feeding claw 6 is provided on the claw frame 4; there are guiding devices between the base 1 and the sliding frame 2, between the sliding frame 2 and the claw frame 4 .

Wherein, the guiding device between the base 1 and the sliding frame 2 is two slide rails 7 arranged on the base 1 and two sliders 8 arranged on the sliding frame 2 and cooperating with the slide rails 7, the sliding frame 2 The guiding device between the claw frame 4 is two guide holes 10 provided on the sliding frame 2 and a guide rod 9 which is arranged in the guide hole 10 and can slide relative thereto; The cylinder 11 is provided with a plug 12 on the jacking cylinder 11, and the plug 12 is aligned with the clamping part of the feeding claw 6; the base 1 is provided with a horizontal limiter 13 that can limit the sliding frame 2, The sliding frame 2 is threadedly connected with a vertical stop 14 that can limit the claw frame 4; the base 1 is connected with a cantilever 18, and the discharge claw 15 pushes the cylinder 16 and the rotary cylinder 17 through the discharge.
