[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for discharging a residual material cut out by machining a machine tool.

[0002]

2. Description of the Related Art For example, when processing a pump seat of a cylinder head of an engine, in order to discharge a residual material generated when the processing is completed, conventionally, a receiving portion of a residual material receiving device installed diagonally below a processing portion is conventionally used. The air cylinder is used to stretch to the machined part, the separated material is received at the receiving part, the air cylinder is retracted, the receiving part is retracted, the remaining material is dropped on the shooter, and the conveyer transports it to the residual material collection box. .

Japanese Utility Model Laid-Open Publication No. 63-13924 discloses a cylinder mounted almost vertically to a moving mechanism for moving in a horizontal plane, an electromagnetic adsorber attached to a tip of a rod of the cylinder, and extending the rod of the cylinder to form a pallet. There is described a material supply device that sucks a material inside, moves a moving device horizontally by shortening a rod of a cylinder, and conveys the material to a hopper. Japanese Utility Model Application Laid-Open No. 62-133584 discloses that a lever that moves vertically and longitudinally includes
There is described a work suction and transfer device in which a support plate to which two electromagnets are fixed is swingably mounted.

[0004]

In the above-mentioned conventional residual material receiving device, the receiving portion of the residual material receiving device installed diagonally below the processing part is extended to the processing part by an air cylinder, and the separated residual material falls. The receiving part must be installed near the processing area, and the chips and cuttings must be placed on the air cylinder of the remaining material receiving device and the transport device installed near it. Fluid spills, causing more failures. Once broken, the installation location of the remnant receiving device is restricted to a narrow place, so it is difficult to adjust and repair,
Productivity decreases. In both of the publications described above, the components are sucked and held by an electromagnet and are transported to a predetermined position, but in each case, the components are sucked and held by an electromagnet from above. Therefore, it is not suitable for reliably receiving a member that is cut off from the workpiece when the processing is completed, such as a residual material after processing.

In the present invention, the residual material separated from the work is sucked and held when the machining is completed, and is extruded from the work while maintaining its posture. It is an object of the present invention to provide a processing residue discharge device which has a small number of pieces and has good security.

[0006]

SUMMARY OF THE INVENTION The present invention is directed to a work remaining material.
The remaining member of the work is attached to the end of the shaft, which is slidable a predetermined distance in the horizontal direction with a spring
An electromagnet fixed to adsorb that site, as well as installing a cylinder for advancing and retracting the support member, established a pusher which is interposed a spring for pressing the portion to be the remainder of the work to the cutter, the strength of the spring In this case, the residual material is larger than the strength of the spring interposed in the supporting member.

[0007]

When the machining of the work is started by the cutter, the air cylinder is actuated to press the electromagnet against the portion of the work which is to be the remaining material, and the electromagnet is energized to be excited. The electromagnet is attracted to the remaining portion of the workpiece while the spring in the support member is slightly compressed. When the cutter advances to the processing position, the pushing member disposed at the center of the cutter hits the work and compresses the spring in the pushing member. When the remaining material is cut off from the work as the workpiece is being processed by the cutter, the remaining material is attracted by the electromagnet, so the spring of the pushing member compresses the spring of the electromagnet with the strong elasticity of the pushing member while maintaining its posture. The remaining material is extruded from the work. When the air cylinder is retracted to demagnetize the electromagnet, the remaining material adsorbed and held by the electromagnet falls from that position and is transported to the collection box.

FIG. 1 is an enlarged front view of a part of an embodiment of the present invention, partly in section, and FIG. 2 is an explanatory view of the operating state of the embodiment. In the figure, reference numeral 1 denotes an electromagnet, which is fixed to the tip of a slide shaft 4 fitted in a support cylinder 3 attached to a mounting plate 2 at an angle α, and the slide shaft 4 has a bottom portion of the support cylinder 3. The sliding shaft 4 is capable of linearly moving in the axial direction by a predetermined distance by a concave groove and a pin engaged with the concave groove. Two pieces are installed in the vertical direction as shown. Mounting plate 2
As shown in FIG. 2, is mounted on a cylinder rod 7 of an air cylinder 6 and is guided by two guide rods 8 to linearly advance and retreat. The base 9 to which the guide block of the air cylinder 6 and the guide rod 8 is attached is
At an offset angle α with the horizontal direction.
In the center of the cutter 11, a spring 1 is provided between the cutter 11 and the bottom of the cutter.
3 and the groove 14 and the pin engaged with the groove 14
The pushing shaft 12 is installed so as to be linearly movable in the axial direction by a predetermined distance, and the elasticity of the spring 13 is set to be stronger than the elasticity of the two springs 5 pressing the shaft 4 to which the electromagnet 1 is fixed. A shooter 16 is installed below the original position (retracted position) of the electromagnet 1,
The collection box 17 is placed below the lower end of the shooter 16.

[0009] Next, the operation of the apparatus for discharging the residual machining material will be described. When the processing of the work W is started by the cutter 11, the air cylinder 6 is actuated to move the mounting plate 2 forward, and the electromagnet 1 is pressed against a portion of the work W which is to be processed as shown by the broken line in FIG. Then, the electromagnet 1 is energized to be excited. The two electromagnets 1 are vertically attracted to the remaining portion of the work with the spring 5 slightly shortened. On the other hand, at a position where the cutter 11 advances and processes the work W, the pushing shaft 12 provided at the center of the cutter 11 hits the work W, and the spring 13 is compressed. Processing of the workpiece W by the cutter 11 proceeds,
When the disc-shaped residual material w is cut off, the residual material w tends to be blown off by the cutting edge of the cutter 11, but is attracted by the electromagnet 1, so that the spring 13 of the pushing shaft 12 has a strong elasticity to spring the electromagnet. 5 is compressed and extruded while being attracted to the electromagnet as shown in FIG.

When the electromagnet 1 is demagnetized by retracting the air cylinder 6 to the original position shown by the solid line in FIG.
It falls down and enters the collection box 17. When the collection box 17 needs to be set far away, the shooter 16 and the collection box 17
A conveyor can be installed between them.

A long stroke air cylinder 6 is used, and the air cylinder 6 has an offset angle α from the horizontal direction.
By attaching the air cylinder 6, the air cylinder 6 can be installed away from the processing position in a place having good security, and the attracting surface of the electromagnet 1 can be abutted at right angles to the remaining material portion. Can be reliably transported to the position. The number of electromagnets is not limited to two, and can be appropriately selected according to the size and weight of the remaining material, and a hydraulic cylinder can be used instead of an air cylinder.

[0012]

[Effects of the Invention] The present invention does not damage the cutter due to the collision of the remaining material with the blade edge of the cutter when the remaining material is separated, and also can reliably transport the remaining material to the discharge position, thereby causing a failure. It is possible to obtain a processing residue discharge device which is small and has good security.
