Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a chip suction device used for removing and cleaning chips generated during cutting work on a machine tool or the like.

[0002]

[Prior Art]

 FIG. 5 shows a conventional chip blower device. The air compressed by the large compressor-4 is sent through the feed pipe 1. The feed pipe 1 is composed of a main pipe 2 and a branch pipe 3 separated from the main pipe 2. The number of branch pipes 3 is determined according to the required number of places of use. A working tool 5 for controlling the blowing and stopping of the compressed air sent from the compressor-4 is attached to the end of each branch pipe 3. This work implement 5 is called a blower gun or the like. This blower gun comprises a blowing part 6 and a grip part 7. The insides of the blowing portion 6 and the grip portion 7 serve as a passage for compressed air. At the lower part of the grip portion 7 is a mounting portion 8 for mounting the end portion of the branch pipe 3. The attachment portion 8 and the outlet 9 communicate with each other. Then, by pulling the trigger 10 provided on the upper portion of the grip portion 7, the compressed air sent from the compressor is blown out from the blowout port 9. Further, the blowing can be stopped by separating the trigger unit 10.

The compressed air of the blower gun blows off the chips generated during the cutting operation of the machine tool to clean the machine tool and the workpiece.

[0004]

[Problems to be solved by the device]

 Since the conventional device blows off the chips with compressed air, there is a problem that the blown chips adhere to the sliding surface of the machine and damage the machine, or soil the floor of the workplace. There was also the danger that the blown chips could get into the eyes of workers.

An object of the present invention is to provide a chip suction device for a machine tool or the like that allows a suction device body to safely and cleanly suck chips and the like by a simple operation of a suction work tool.

[0006]

[Means for Solving the Problems]

 In this invention, in a chip suction device such as a machine tool in which a suction work tool for suction work is provided at the end of a feed pipe mounted on the suction device body, in the chip suction device, the operation lever provided on the suction work tool and the operation described above. The piston rod and piston interlocking with the lever are moved to the piston storage part in the work implement and the suction passage is opened to control the suction work and stop.

[0007]

[Action]

 As a result of the configuration described above, the chips generated during the work on the machine tool are sucked by the suction work tool operated by the operation lever and collected in the suction device body through the feed pipe. For this reason, the cutting chips do not scatter anywhere and do not damage the machine tool or workpiece.

【Example】

 1 to 4 show an embodiment of the present invention. The same reference numerals are used for the same components as in the conventional example, and detailed description thereof is omitted.

1 to 3 show a first embodiment. The main pipe 2 of the feed pipe 1 attached to the suction device body 11 is provided with as many branch pipes 3 as necessary. A suction work tool 12 is attached to each of the ends of the branch pipes 3. The suction work instrument 12 includes a suction portion 13 and a grip portion 14. The suction portion 13 is a U-shaped pipe, and includes a suction passage portion 15 which is one of the U-shaped straight portions and a cylinder portion 16 which is the other straight portion. The tip of the suction passage portion 15 is open. The cutting dust is sucked from the opening 17, but at that time, a rubber protection pipe 18 is attached to the outer periphery of the opening 17 so as not to damage the workpiece or the machine. A piston 19 and a piston rod 20 are housed in the cylinder portion 16. Both ends of the piston rod 20 are threaded so that they penetrate the piston 19 and are fixed with nuts 21. A closing member 22 is fitted on the end of the cylinder portion 16 to close the cylinder portion 16.

An annular groove 23 is provided in the piston 19 housed in the cylinder portion 16. The O-ring 24 is mounted in the annular groove 23, and at this time, the O-ring 24 is held by the wiper 25 so as to be sandwiched in the annular groove 23. Since the wiper 25 protects the O-ring 24 from the chips sucked, the O-ring 24 can maintain the sealing function between the piston 19 and the cylinder portion 16. Further, the end of the piston rod 20 on the side opposite to the side fixed to the piston 19 penetrates the closing member 22 and projects to the outside of the cylinder portion 16. In the cylinder portion 16, a spring 26 is provided between the piston 19 and the closing member 22 around the piston rod 20 as an axis.

An operation lever 27 for starting and stopping the suction work is attached to the back of the grip 14. The operating lever 27 has a dogleg shape, and includes an operating portion 28 and an operating portion 29. A hole 30 for attaching to the grip portion 14 is provided at the fulcrum portion of the dogleg. The hole 30 and the hole 31 of the attachment portion 36 of the operation lever 27 provided behind the grip portion 14 are aligned with each other, and the pin 32 is inserted and fixed. At this time, the pin 32 is inserted so that the operation lever 27 can swing around the pin 32. Further, a hole 33 for receiving the piston rod 20 projecting through the closing member 22 of the cylinder portion 16 is formed in the operating portion 29 of the operation lever 27. One end of the piston rod 20 protruding from the closing member 22 is passed through the hole 33, and the operating portion 29 side is stopped by a nut 34. Since the operation lever 27 and the piston rod 20 are mounted in this manner, the piston 19 is also moved in association with the movement of the operation lever 27.

In the suction working instrument 12 configured as described above, the operation lever 27 is normally located as shown in FIG. At this time, the piston 19 connected to the operation lever 27 via the piston rod 20 is pushed toward the opening 17 by the spring 26. The position of the piston 19 in this state is a position where the passage 35 in the grip portion 14 communicating with the cylinder portion 16 and the suction passage 37 in the suction passage portion 15 are blocked. Therefore, even if the suction force from the branch pipe 3 connected to the grip portion 14 acts on the suction work instrument, the suction force is blocked by the piston 19 and does not reach the opening 17. When the operating portion 28 of the operating lever 27 is gripped, the operating portion 29 of the operating lever 27 is pulled toward the piston rod 20 closing member 22 side. As a result, the piston 19 is also pulled toward the closing member 22, and the suction passage 37 and the passage 35 of the grip portion 14 are communicated with each other. -Since it does not touch the seal part, the sealing property does not deteriorate. In this state, the suction force from the branch pipe 3 acts on the opening 17 to suck the cutting chips.

The second embodiment shown in FIG. 5 is different from the first embodiment in that the suction portion 13 is changed from the U-shape of the first embodiment to the linear shape. The reason why the suction portion 13 is U-shaped in the first embodiment is that the suction lever 13 is operated by pulling it with a fingertip when the operation lever 27 is grasped, and the suction portion 13 is linear in the second embodiment. The mold is used to operate the suction work instrument 12 by pushing it with the palm when the operation lever 27 is gripped. Except for the difference in the suction part 13, all other configurations are the same as in the first and second embodiments.

[0014]

【effect】

 When the suction work implement is moved closer to the machine tool or work piece and the operating lever of the suction work implement is gripped, the piston linked with the operating lever opens the suction passage. As a result, the suction force from the suction device body is transmitted to the suction work tool via the feed pipe, and the chips generated during the cutting work of the machine tool are sucked. At this time, since the piston is housed in the piston housing portion, for example, it is possible to prevent the sealing function from being deteriorated by damaging the seal portion of the piston by the sucked chips and the like. And, if it is sucked in this way, the chips will not scatter and adhere to the machine tool or the work piece or be damaged. In addition, it is effective for various kinds of damage caused by scattering of cutting chips, for example, for the safety and health management of workers such as when the chips enter the eyes of the workers and inhale the oil blown off with the chips. It also has the effect of keeping the main body of the machine, the interior and the floor of the workplace clean.
