A three-color warning light for a numerical control machine tool

Abstract

The present invention discloses a three-color warning light for a numerical control machine tool, which includes a base. An annular expansion airbag is fixedly adhered to the outside of the middle column. An elastic bushing is positioned and installed at the outer side end of the annular expansion airbag. More than one arc-shaped positioning cavity is formed in a circle around the outer wall surface of the elastic bushing, and a warning light rod is arranged in each arc-shaped positioning cavity. For the three-color warning light of the present invention, when in the red alarm state, the elastic bushing makes an expanding and shrinking breathing motion, and the warning light rod realizes a motion state of rotating and moving at the same time. During this process, omnidirectional light projection can be achieved, and a better warning effect can be obtained. When the whole warning light rod is pushed out to the limit position, the outer diameter of the whole warning light and the warning light rod can be made larger and more eye-catching. Moreover, the structure of rotating and moving at the same time can enable the three-color lamp cover to remain clean for a long time, preventing the problem of reduced brightness caused by dust adhesion.

Description

Technical Field

[0001] The present invention relates to a warning light, and more particularly to a three-color warning light for a numerically controlled machine tool. Background Art

[0002] Machine tool warning lights generally have three states. The green light represents normal operation, the yellow light represents the standby state, and the red light represents a malfunction. Therefore, when in use, different colors will be displayed in different states. However, since the volume of such warning lights is fixed, when a malfunction occurs, because the state is relatively important, if the red warning light is not noticed in time, more serious accidents will occur. For the warning light in the red alarm state, if it is just a fixed display state, it is easy for the staff to be distracted by other things, resulting in the failure to observe the malfunction warning light in time and causing serious economic losses.

[0003] In addition, since the three-color light is exposed to the working environment for a long time, in the machining environment of the machine tool, the entire working environment has a large amount of dust. After a long time, it is easy to cover the outside of the three-color light with dust. The covered dust will cause the display brightness of the three-color lamp cover to decrease and is not easy to attract attention. Therefore, it needs to be cleaned regularly, which is very troublesome. Summary of the Invention

[0004] The technical problem to be solved by the present invention is a three-color warning light for a numerically controlled machine tool, which can achieve a moving and rotating motion state, realize the projection of light at different angles, and use the light to be projected in different directions, so that the operator can be more easily attracted by the light, and thus better master the operating state of the machine tool. And this motion mode can expand the volume of the entire three-color light, and at the same time, the moving state is more likely to attract people's attention. Moreover, this motion mode can also automatically clean the lamp cover, prevent dust adhesion, effectively reduce the number of manual cleanings, keep the light transmittance of the three-color lamp cover for a long time, and effectively solve the deficiencies in the prior art.

[0005] The present invention is achieved through the following technical solutions: A three-color warning light for a numerically controlled machine tool includes a base. A middle column is fixedly arranged at the center of the upper end of the base. An annular expansion airbag is fixedly adhered to the outside of the middle column. An elastic bushing is positioned and installed at the outer side end of the annular expansion airbag. One or more arc-shaped positioning cavities are formed around the outer wall surface of the elastic bushing in a circle. A warning light rod is arranged in each arc-shaped positioning cavity. A warning light board is arranged in the warning light rod. Three-color lamp beads are arranged in zones from top to bottom on the warning light board. The bottom of each warning light rod is slidably arranged on the guiding slide rod at the upper end of the base. After the annular expansion airbag is inflated and expanded, it pushes out the elastic bushing, and makes the warning light rod rotate and slide along the guiding slide rod.

[0006] As a preferred technical solution, the warning lamp post includes a three-color lamp shade, a lamp board mounting rod, and a slider. The slider is installed at the bottom of the lamp board mounting rod. The slider is slidably assembled with a guiding slide rod. The three-color lamp shade is installed outside the lamp board mounting rod. The bottom of the lamp board mounting rod passes through the three-color lamp shade and extends to the bottom of the three-color lamp shade. The lamp board mounting rod is rotatably connected to the three-color lamp shade through a bearing. A part of the three-color lamp shade is buckled into an arc-shaped positioning cavity, and the bottom of the three-color lamp shade extends to the lower end surface of the elastic bushing.

[0007] As a preferred technical solution, a driving wheel is arranged at the position where the three-color lamp shade extends to the bottom of the elastic bushing. A driving rod is arranged on one side of the driving wheel. The driving rod is arranged on one side of the guiding slide rod, and one side surface of the driving rod is in rolling engagement with the driving wheel.

[0008] As a preferred technical solution, the driving rod includes a C-shaped bracket. A driving strip is embedded on the side of the bracket opposite to the driving wheel. Transmission teeth are arranged on the surface of the driving strip. Transmission tooth grooves are arranged on the driving wheel. The transmission teeth are engaged with the transmission tooth grooves. The three-color lamp shade rotates relative to the lamp board mounting rod through a bearing.

[0009] As a preferred technical solution, the elastic bushing is made of an elastic rubber material with elastic deformation recovery ability. A cleaning cotton layer is arranged on the arc-shaped surface of the arc-shaped positioning cavity, and contacts the outer wall surface of the three-color lamp shade through the cleaning cotton layer.

[0010] As a preferred technical solution, the elastic bushing is annular, and the contact ends of its inner side surface and the outer wall surface of the expansion airbag are connected and positioned through connecting screws.

[0011] As a preferred technical solution, a control main board and an air pump are fixedly installed in the base. The output end of the air pump is connected and communicated with the expansion airbag through a connecting pipe. An exhaust pipe is further arranged at the output end of the expansion airbag. An electromagnetic valve is installed on the exhaust pipe. The opening and closing of the electromagnetic valve are controlled by the control main board. The control main board is connected to the servo system of the data machine tool.

[0012] As a preferred technical solution, corresponding reflective coatings are arranged on the elastic bushing from top to bottom corresponding to the three-color lamp beads.

[0013] As a preferred technical solution, a plurality of prism bars protruding inwards are arranged on the inner side surface of the three-color lamp shade.

[0014] The beneficial effects of the present invention are as follows: 1. The present invention divides the entire lamp body structure into a plurality of warning lamp poles. When a red alarm occurs, an air pump inflates the expansion airbag, so that the expansion airbag expands after being inflated to expand the elastic bushing, and the expanded elastic bushing is used to drive the warning lamp pole to move toward the far end. During this process, the entire warning light becomes in motion, and an object in motion is more likely to attract people's attention, and the warning effect is better. In addition, the fully inflated expansion airbag can increase the volume of the entire warning light, making it more obvious.

[0015] Second, in the present invention, since the driving wheel at the bottom of the entire three-color lampshade contacts the driving rod when the elastic bushing expands, when the entire warning lamp pole moves along the guide slide bar, it is in a state of moving and rotating. In this way, the rotating three-color lampshade cooperates with the structure of the prism bar to realize the projection of light at different angles and directions, and can use the light irradiated from different angles to attract the attention of the operator, so as to obtain a better warning effect;

[0016] Third, because the warning light pole of the present invention is in a moving and rotating state when it is in the expanded and stretched state, when the three-color lampshade rotates relative to the cleaning cotton layer, the rotating structure can be used to clean the dust on the surface to prevent the adhesion of dust, thereby effectively ensuring the clarity of the three-color lampshade.

[0023] All features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any way.

[0024] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically described, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically described, each feature is only an example of a series of equivalent or similar features.

[0025] As Figure 1 and Figure 2 shown, a three-color warning light for a numerical control machine tool according to the present invention includes a base 1. A middle column 9 is fixedly arranged at the center of the upper end of the base 1. An annular expansion airbag 11 is fixedly adhered to the outside of the middle column 9. An elastic bushing 2 is positioned and installed at the outer side end of the annular expansion airbag 11. More than one arc-shaped positioning cavity 4 is formed in a circle around the outer wall surface of the elastic bushing 2. A warning light rod is arranged in each arc-shaped positioning cavity 4. A warning light board 8 is arranged in the warning light rod. Tri-color lamp beads are arranged in zones from top to bottom on the warning light board 8. The bottom of each warning light rod is slidably arranged on a guide slide rod 5 at the upper end of the base 1. After the annular expansion airbag 11 is inflated and expanded, it pushes out the elastic bushing 2, and makes the warning light rod rotate and slide along the guide slide rod 5.

[0026] As Figures 3 - 5 shown, the warning light rod includes a three-color lamp cover 6, a lamp board mounting rod 7, and a slider 13. The slider 13 is installed at the bottom of the lamp board mounting rod 7. The slider 13 is slidably assembled with the guide slide rod 5. The three-color lamp cover 6 is installed outside the lamp board mounting rod 7. The bottom of the lamp board mounting rod 7 passes through the three-color lamp cover 6 and extends to the bottom of the three-color lamp cover 6. The lamp board mounting rod 7 is rotatably connected to the three-color lamp cover 6 through a bearing 19. A part of the three-color lamp cover 6 is buckled into the arc-shaped positioning cavity 4. The bottom of the three-color lamp cover 6 extends to the lower end surface of the elastic bushing 2.

[0027] As Figure 4 and Figure 5As shown in the figure, a driving wheel 14 is provided at the bottom position where the three-color lamp shade 6 extends to the bottom of the elastic bushing 2. A driving rod 3 is provided on one side of the driving wheel 14. The driving rod 3 is arranged on one side of the guiding slide rod 5, and one side surface of the driving rod 3 is in rolling engagement with the driving wheel 14. The driving rod 3 includes a C-shaped bracket 31. A driving strip 32 is embedded on the side of the bracket opposite to the driving wheel. Transmission teeth are provided on the surface of the driving strip 32, and transmission tooth grooves are provided on the driving wheel 14. The transmission teeth are engaged with the transmission tooth grooves. The three-color lamp shade 6 rotates relative to the lamp panel mounting rod 7 through a bearing 19. When the elastic bushing 2 is inflated and expanded by the inflated expansion airbag 11, the elastic bushing 2 expands, and then pushes the corresponding warning lamp rod to move along the guiding slide rod 5. During the movement, the slider 13 slides along the guiding slide rod 5. Since the three-color lamp shade 6 is rotationally connected to the lamp panel mounting rod 7 through a bearing 19, and the slider 13 is arranged at the bottom of the lamp panel mounting rod 7, the lamp panel mounting rod 7 only translates and does not rotate during the movement. However, the driving wheel on one side of the three-color lamp shade is engaged with the driving rod, so the moving three-color lamp shade will be driven to rotate. At this time, the entire three-color lamp shade is continuously in a rotating state, achieving the purpose of rotating while moving. When the elastic bushing shrinks, the three-color lamp shade rotates in the reverse direction.

[0028] In this embodiment, the elastic bushing 2 is made of an elastic rubber material with elastic deformation recovery ability. A cleaning cotton layer 18 is provided on the arc surface of the arc-shaped positioning cavity 4. By contacting the outer wall surface of the three-color lamp shade with the cleaning cotton layer 18, when the three-color lamp shade rotates relative to the cleaning cotton layer, the cleaning cotton layer can be used to clean the outside of the three-color lamp shade, preventing the accumulation of dust and affecting the light transmittance of the three-color lamp shade.

[0029] As Figure 1 and Figure 3 shown, the elastic bushing 2 is annular, and the contact ends of its inner side surface with the outer wall surface of the expansion airbag 11 are connected and positioned through connecting screws 12. Therefore, the entire elastic bushing 12 is suspended and supported through the connecting screws 12, enabling the elastic bushing and the expansion airbag to move synchronously.

[0030] Among them, a control main board 16 and an air pump 17 are fixedly installed in the base. The output end of the air pump 17 is connected and conducted with the expansion airbag 11 through a connecting pipe. An exhaust pipe is also provided at the output end of the expansion airbag 11, and an electromagnetic valve is installed on the exhaust pipe. The opening and closing of the electromagnetic valve are controlled by the control main board. The control main board is connected to the servo system of the data machine tool. When the red fault lamp lights up, a control instruction is sent from the servo system to the control main board, and the control main board controls the air pump to inflate, realizing the expansion of the expansion airbag, and then realizing the expansion action of the elastic bushing, achieving the purpose of automatic control.

[0031] Among them, the elastic bushing 2 is provided with corresponding reflective coatings corresponding to the three-color lamp beads from top to bottom, and the reflective coatings are used to increase the brightness when the three-color lamp lights up.

[0032] In this embodiment, the inner side of the three-color lampshade 6 is provided with a plurality of prism strips convex inwardly, so when the prism strips rotate with the three-color lampshade, the light of the three-color lampshade can be dispersed, and then the light can be projected at different angles to achieve the light projection in the space, so as to achieve a better attraction purpose and enhance the warning effect, such as Figure 3 shown.

[0033] The beneficial effects of the present invention are as follows: 1. The present invention divides the entire lamp body structure into a plurality of warning lamp poles. When a red alarm occurs, an air pump inflates the expansion airbag, so that the expansion airbag expands after being inflated to expand the elastic bushing, and the expanded elastic bushing is used to drive the warning lamp pole to move toward the far end. During this process, the entire warning light becomes in motion, and an object in motion is more likely to attract people's attention, and the warning effect is better. In addition, the fully inflated expansion airbag can increase the volume of the entire warning light, making it more obvious.

[0034] Second, in the present invention, since the driving wheel at the bottom of the entire three-color lampshade contacts the driving rod when the elastic bushing expands, when the entire warning lamp pole moves along the guide slide bar, it is in a state of moving and rotating. In this way, the rotating three-color lampshade cooperates with the structure of the prism bar to realize the projection of light at different angles and directions, and can use the light irradiated from different angles to attract the attention of the operator, so as to obtain a better warning effect;

[0035] Third, because the warning light pole of the present invention is in a moving and rotating state when it is in the expanded and stretched state, when the three-color lampshade rotates relative to the cleaning cotton layer, the rotating structure can be used to clean the dust on the surface to prevent the adhesion of dust, thereby effectively ensuring the clarity of the three-color lampshade.

[0036] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
