DETAILED DESCRIPTION

[0022] The present invention will be described in detail below in conjunction with the embodiments shown in the accompanying drawings. However, the embodiments do not limit the protection scope of the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on the embodiments are all within the protection scope of the present invention.

[0023] The utility model discloses a chip removal device for a machine tool workbench, such as Figure 1-Figure 4 As shown, it includes a reduction unit 17 and a curved pipe 15. The reduction unit 17 is an existing component composed of a gear reduction box and a motor, and the curved pipe 15 is in an Ω shape as a whole. The reduction unit 17 is installed at one end of the curved pipe 15 and is used to reciprocate the curved pipe 15.

[0024] The bent pipe 15 is fixedly installed with a base plate 7, and a driving motor 1 is fixedly installed with the base plate 7. A transmission shaft 5 is rotatably installed with the base plate 7 through a bearing seat. The transmission shaft 5 is connected to the output end of the driving motor 1, and the transmission shaft 5 can be rotated clockwise or counterclockwise by the driving motor 1; the transmission shaft 5 is provided with a pair of small pitch thread segments 3 and a pair of large pitch thread segments 2, the small pitch thread segments 3 are located between the large pitch thread segments 2, the small pitch thread segments 3 are all screwed with a slow slider 4, and the large pitch thread segments 2 are all screwed with a fast slider 8, and the rotating transmission shaft 5 can synchronously drive the slow slider 4 and the fast slider 8 via the small pitch thread segments 3 and the large pitch thread segments 2.

[0025] The side walls of the slow slider 4 are rotatably installed with a connecting fork 13 through a rotating seat, and the interior of the connecting fork 13 is fixedly installed with a delivery pipe 11, and the delivery pipe 11 is evenly connected with a nozzle 12, and the delivery pipe 11 is connected and assembled with the elbow 15 through a hose 14, and the delivery pipe 11 is connected and assembled with the fast slider 8 through a transmission component; when the slow slider 4 and the fast slider 8 are in motion, the transmission component and the two ends of the connecting fork 13 are rotated, and the direction of the nozzle 12 can be changed while the connecting fork 13 is relatively moved (toward or away from each other), so that the medium (water or air) transported in the elbow 15 can be sprayed evenly and comprehensively on the machine tool workbench.

[0026] Specifically, Figure 2As shown, the transmission assembly includes a transmission rod 10 and a roller 6. The roller 6 is rotatably installed on the side of the fast slider 8 away from the base plate 7. The transmission rod 10 is provided with a long hole 9. One end of the transmission rod 10 is fixedly assembled with the conveying tube 11, and the roller 6 is slidably arranged inside the long hole 9; when the connecting fork 13 and the conveying tube 11 move in opposite directions with the slow slider 4, the roller 6 moves in opposite directions with the fast slider 8, and at the same time, the roller 6 moves along the long hole 9, thereby realizing the action of swinging the conveying tube 11 with the rotating seat as the center.

[0027] Specifically, the thread rotation directions of the two small-pitch thread segments 3 are opposite, the thread rotation directions of the two large-pitch thread segments 2 are opposite, and the thread rotation directions of the small-pitch thread segment 3 and the large-pitch thread segment 2 located at the same end are opposite; to ensure that the two slow sliders 4 can move in opposite directions, the two fast sliders 8 can move in opposite directions, and the moving directions of the slow slider 4 and the fast slider 8 at the same end are also opposite.

[0028] Because the pitch of the small pitch thread segment 3 is smaller than the pitch of the large pitch thread segment 2, the length of the small pitch thread segment 3 must be smaller than the large pitch thread segment 2 to ensure that the time it takes for the slow slider 4 to travel along the small pitch thread segment 3 is the same as the time it takes for the fast slider 8 to travel along the large pitch thread segment 2.

[0029] Specifically, the base plate 7 is fixedly mounted with a guide rod 20, and the slow slider 4 and the fast slider 8 are both provided with guide grooves, which are slidably assembled with the guide rod 20; when the slow slider 4 and the fast slider 8 translate, the guide grooves also move along the guide rod 20, thereby improving the smoothness and accuracy of the movement.

[0030] Specifically, Figure 1 As shown, the base plate 7 is installed with a cover 19 for protecting the internal components from corrosion by the external environment; at the same time, the cover 19 is provided with an avoidance groove 18 for passing the roller 6 and the connecting fork 13 without affecting the reciprocating movement of the roller 6 and the connecting fork 13.

[0031] When installing the device, bearings 16 are installed at both ends of the elbow 15. The bearings 16 are installed on the side wall of the machine tool chassis to reduce the resistance of the swing of the elbow 15. The speed reducer unit 17 is also fixedly installed on the side wall of the machine tool chassis.

[0032] The reduction gear unit 17 and the drive motor 1 are electrically connected to the control button on the machine tool control panel through the guide. The elbow 15 is closed at one end and open at the other end. When the conveying medium in the elbow 15 is water, the open end of the elbow 15 is connected to an external water tank with a conveying pump; when the conveying medium in the elbow 15 is air, the open end of the elbow 15 is connected to an air pump.

[0033] Now Figure 2 The working method of this embodiment is introduced based on the direction of rotation of the thread:

[0034] In the initial state, the reduction gear unit 17 swings the elbow 15 and the components thereon to a horizontal position and is located at the rear side of the machine tool worktable without affecting the normal processing of the machine tool. The nozzles 12 on both sides are tilted toward a central position for standby use.

[0035] During operation, the reduction unit 17 first swings the elbow 15 until the nozzle 12 is directly above the workbench, and then the high-pressure medium is introduced into the elbow 15. The medium sprayed from the nozzles 12 on both sides first cleans the middle of the workbench and blows the debris away from the workbench; then the motor 1 is driven to rotate clockwise, and the two small-pitch thread segments 3 can slowly move the slow slider 4 away from each other, gradually increasing the spacing between the conveying pipes 11, and at the same time, the two fast sliders 8 move quickly towards each other, so that the roller 6 moves along the long strip hole 9, thereby lifting the transmission rod 10, and swinging the conveying pipe 11 away from each other with the rotating seat as the center, so as to flush the debris on the workbench from the middle to both sides, which is beneficial to the removal of the debris. At this time, the elbow 15 can also be swung to adjust the flushing angle for more detailed cleaning. After completion, it is reset for standby use.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0037] In addition, it should be understood that although the present specification is described according to embodiments, not every embodiment contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that those skilled in the art can understand.
