Description

Automatic feeding machine tool for electric fittings with replaceable hopper

technical field

The invention belongs to the technical field of machine tool structure design, be specifically related to a kind of special automatic feeding machine tool for electric power fittings of a replaceable hopper.

Background technique

Existing machine tool, its automatic feeding device generally comprises the hopper that is fixedly arranged on the machine tool body, and this hopper has a fixed discharge port, and in the work, the workpiece in the hopper falls in the preset position successively from the discharge port, thereby Process each workpiece. Since the hopper cannot be disassembled, and there is only a single hopper, when the hopper is deformed due to bumping, the main workpiece is likely to be stuck, and the disassembly and maintenance are relatively complicated; in addition, this single fixed hopper is difficult to realize industrialized automatic loading and unloading of materials.

[0003] The structure of the current power fittings is becoming more and more complicated, and it is often necessary to carry out finishing processing again after casting. Because the power fittings are mostly mass-produced, if continuous processing can be adopted, the production cost can be effectively reduced.

(Embodiment 1)

1 to 7 show a specific embodiment of the present invention, wherein, FIG. 1 is a schematic diagram of a three-dimensional structure of the present invention; FIG. 2 is a schematic diagram of a three-dimensional structure after the machine tool shown in FIG. 1 removes the hopper; Fig. 3 is a partial enlarged view of the place A in Fig. 2; Fig. 4 is a schematic view of a three-dimensional structure of the hopper in the machine tool shown in Fig. 1; Fig. 5 is a top view of the hopper shown in Fig. 4; A schematic cross-sectional structure diagram of the shown hopper; FIG. 7 is a schematic structural diagram of the hopper shown in FIG. 4 resting on the hopper support.

The present embodiment is a special automatic feeding machine tool for electric power fittings, as shown in Fig. 1 to Fig. 7, comprising a machine tool body 1, a hopper 2, and a hopper support 3 arranged on the machine tool body. The workpiece 100 to be processed is placed in the hopper, and the hopper is detachably arranged on the hopper support.

Hopper is provided with hooking part 21, front baffle 22, rear baffle 23, two side plates 24, bottom plate 25 and reset mechanism 26; Back baffle, two side plates and bottom plate are fixedly connected; Reset mechanism It includes a limiter 261, a positioning member 262, a sliding column 263 and a return spring 264; the limiter is fixedly arranged on the outer wall of each side plate, the upper end of the limiter is provided with an upper stop 2611, and the lower end is provided with a lower stop 2612; The upper and lower ends of the sliding column are respectively fixed on the upper stop and the lower stop; the positioning piece is sleeved on the sliding column and is fixedly connected with the front baffle; the return spring is located between the upper stop and the top wall of the positioning piece, The positioning member moves back and forth along the sliding column under the external force and the reset elastic force of the reset spring, and synchronously drives the front baffle to move back and forth; in the free state, the front baffle, the rear baffle, the two side plates and the bottom plate are combined to form a lower part The closed storage trough 27; the hopper bracket is provided with a door-opening pusher 31, when the hopper is placed on the hopper bracket, the door-opening pusher is abutted on the positioning member, thereby overcoming the restoring force of the spring, so that the positioning member and the front The baffle moves up a certain distance. When the positioning piece is forced to move upwards and drives the front baffle to move up, an opening is formed between the bottom of the front baffle and the front of the bottom plate, and the opening is used as the discharge port of the hopper. This structure makes the hopper have no outlet when the hopper is not resting on the hopper bracket, and the workpiece will not fall from the hopper. When the hopper rests on the hopper support, the positioning piece and the front baffle will move up to open the discharge port, so that the workpieces can automatically slide out from the storage trough in sequence.

The hopper also includes two adjustment plates 28 located in the two side plates, each side plate is provided with a screw hole 241 and an adjustment stud 242 located in the screw hole, and the inner end of the adjustment stud is rotated and arranged adjacent to the On one of the adjusting plates, rotating the adjusting stud can drive the adjusting plate to move back and forth. The advantage of this structure is that there may be differences in the length of the workpieces 100 processed in each batch. For example, the length of the workpiece in the previous batch is 30 cm, and the length of the workpiece in this batch is 20 cm. If a hopper with a spacing width of 30 cm is used to It is said that when a workpiece with a length of 20 cm is placed in it, when it slides freely, it will cause the workpiece to deflect, or even get stuck in the hopper; the structure of this embodiment can adapt to the adjustment of the distance between the two adjustment plates. A variety of workpieces with different lengths are available to ensure that the workpieces can slide down from the hopper outlet in an orderly manner.

Machine tool body comprises base 11, milling head 12, the clamping chamber, feed positioning plate 13 and pneumatic pusher mechanism 14 that run through the milling head; It is set at the place between the pneumatic pusher and the milling head. The workpiece slips from the discharge port in the hopper and just falls on the feeding positioning plate 13. After the pneumatic pushing mechanism receives the signal, it pushes the workpiece from the feeding positioning plate 13 into the clamping cavity of the milling head. Clamp the workpiece and process it with the tool head.

[0013] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those of ordinary skill in the art, changes or modifications in other different forms can also be made on the basis of the above description. There is no need and cannot be exhaustive of all implementations here. And these obvious changes or changes derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
