Description
Technical Field
[0001] The utility model relates to the technical field of numerical control machining supporting facilities, and specifically relates to a tool rest for a numerical control lathe. Background Technique
[0002] The numerical control lathe is one of the most widely used numerical control machine tools. It is mainly used for the cutting machining of the inner and outer cylindrical surfaces of shaft parts or disc parts, the inner and outer conical surfaces with any cone angle, the complex revolving inner and outer curved surfaces, and cylindrical and conical threads, etc., and can perform grooving, drilling, reaming, boring and other operations; there are various types of tools for the numerical control lathe, mainly selecting different shaped tools or tools with different materials according to different situations. Since there are many types of tools, if the numerical control lathe is not equipped with a tool magazine for automatic tool change, then at most about four tools can be installed on the numerical control lathe, and the extra tools need to be stored in containers such as tool rests and tool boxes.
[0003] After the existing tool rest for the numerical control lathe places the tool, the tool tip part is usually exposed outside. First, the displacement, shaking and vibration of the tool rest are very likely to cause the tool tip to collide with or rub against the tool rest, thereby causing wear of the structure and reducing the service life of the tool. Second, when the staff rummages for the required tool, it is very easy to be scratched by the tool tip, which has a certain potential safety hazard. Content of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide a tool rest for a numerical control lathe to solve the technical problems mentioned in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A tool rest for a numerical control lathe, including a counterweight base. Both sides of the top of the counterweight base are fixed with brackets, and a first limiting plate and a second limiting plate are respectively fixed between the two brackets. Buffer pads are connected to the bottoms of the first limiting plate and the second limiting plate. One side of the bracket is connected with an adjusting plate through a torsion spring shaft, and a placing cylinder is fixed on the outer surface of the adjusting plate. A viewing window is connected to the outer surface of the placing cylinder. A buffer ring and a buffer sleeve are respectively connected inside the placing cylinder, and drain ports are opened at the bottom of the buffer sleeve and the placing cylinder.
[0006] By adopting the above technical solution, turn the adjusting plate downward to tilt the placing cylinder. Then, the tool head can be turned downward to place the tool into the placing cylinder. After that, release the rotating adjusting plate, and drive the adjusting plate to reset through the torsion spring shaft, making the placing cylinder abut against the second limiting plate, so that the adjusting plate and the placing cylinder return to the vertical state. At this time, the first limiting plate or the second limiting plate blocks the upper part of the placing cylinder to prevent the tool from falling upward; multiple placing cylinders place multiple tools separately, and there will be no contact with other tools during picking and placing, and the tool head is downward at the lower part inside the placing cylinder. When picking and placing, the handle of the tool is grasped, so it is avoided that the worker's hand is scratched by the tool head; during storage, through the settings of the buffer pad, buffer ring and buffer sleeve, it is avoided that the tool is damaged due to displacement resulting in friction and collision; when it is necessary to take out later, the shape of the tool head can be viewed through the window, so as to facilitate the identification of the type of tool and avoid taking the wrong one. Since the tool head is placed downward, the cutting fluid remaining on the surface of the tool head can flow into the drain port, and then the cutting fluid passes through the drain port and drops on the top of the second limiting plate, and the cutting fluid is guided away through the slope on the top of the second limiting plate to prevent the cutting fluid from dripping into the placing cylinder below.
[0007] Further, the top of the second limiting plate is in a slope shape, and the placing cylinder abuts against the second limiting plate.
[0008] By adopting the above technical solution, the torsion spring shaft drives the adjusting plate to reset, making the placing cylinder abut against the second limiting plate, so that the adjusting plate and the placing cylinder return to the vertical state. Since the tool head is placed downward, the cutting fluid remaining on the surface of the tool head can flow into the drain port, and then the cutting fluid passes through the drain port and drops on the top of the second limiting plate, and the cutting fluid is guided away through the slope on the top of the second limiting plate to prevent the cutting fluid from dripping into the placing cylinder below.
[0009] Further, the buffer pad, buffer ring and buffer sleeve are all made of silicone material.
[0010] By adopting the above technical solution, during storage, through the settings of the buffer pad, buffer ring and buffer sleeve, it is avoided that the tool is damaged due to displacement resulting in friction and collision.
[0011] Further, the window is made of acrylic material.
[0012] By adopting the above technical solution, when it is necessary to take out later, the worker can view the shape of the tool head through the window, so as to facilitate the identification of the type of tool and avoid taking the wrong one.
[0013] Further, the adjusting plate is rotatably connected to the bracket through a torsion spring shaft.
[0014] By adopting the above technical solution, the worker turns the adjusting plate downward to tilt the placing cylinder. Then, the worker can turn the tool head downward to place the tool into the placing cylinder. After that, the worker releases the rotating adjusting plate, and the torsion spring shaft drives the adjusting plate to reset.
[0015] Further, a roller is connected to the middle of the top of the counterweight base, and a collection box is placed on the top of the roller, and a baffle is fixed to the back of the counterweight base.
[0016] By adopting the above technical solution, the drained cutting fluid falls into the collection box. When it is necessary to clean the collection box, the staff only needs to grasp the collection box and pull it out in the direction of the outer surface of the counterweight base. At the same time, the rolling of the roller reduces the frictional resistance between the collection box and the counterweight base, so as to facilitate the staff to take and place. After pouring, the staff pushes the collection box back above the counterweight base, and at the same time, the baffle limits the collection box to prevent the collection box from falling off the back of the counterweight base.
[0017] Further, the collection box abuts against the baffle.
[0018] By adopting the above technical solution, after pouring, the staff pushes the collection box back above the counterweight base, and at the same time, the baffle limits the collection box to prevent the collection box from falling off the back of the counterweight base.
[0019] Further, a plurality of rollers are provided, and the plurality of rollers are equidistantly distributed.
[0020] By adopting the above technical solution, the collection box can be grasped and pulled out in the direction of the outer surface of the counterweight base. At the same time, the rolling of the roller reduces the frictional resistance between the collection box and the counterweight base, so as to facilitate the staff to take and place.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as limiting the present utility model.
[0030] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.
[0031] Embodiment 1:
[0032] A tool rest for a numerical control lathe, as Figures 1-4As shown in the figure, it includes a counterweight base 1. On both sides of the top of the counterweight base 1, brackets 2 are fixedly installed. Between the two brackets 2, a first limiting plate 7 and a second limiting plate 8 are respectively fixedly installed. The first limiting plate 7 or the second limiting plate 8 blocks the upper part of the placing cylinder 5 to prevent the tool from falling off upward. One side of the bracket 2 is connected to an adjusting plate 3 through a torsion spring shaft 4. The adjusting plate 3 is rotationally connected to the bracket 2 through the torsion spring shaft 4. The staff rotates the adjusting plate 3 downward to tilt the placing cylinder 5. Then the staff can place the tool with the tool head facing down into the placing cylinder 5. After that, the staff releases the rotation of the adjusting plate 3, and the torsion spring shaft 4 drives the adjusting plate 3 to reset so that the placing cylinder 5 abuts against the second limiting plate 8. There are multiple adjusting plates 3, second limiting plates 8 and buffer pads 9. The multiple adjusting plates 3, second limiting plates 8 and buffer pads 9 are evenly distributed at equal intervals. The outer surface of the adjusting plate 3 is fixedly installed with a placing cylinder 5, which is convenient for placing tools separately. The placing cylinder 5 abuts against the second limiting plate 8. A viewing window 6 is connected to the outer surface of the placing cylinder 5. The viewing window 6 is made of acrylic material. When it needs to be taken out later, the staff can view the shape of the tool head through the viewing window 6, so as to facilitate the identification of the type of tool and avoid taking the wrong one. Buffer pads 9 are connected to the bottoms of both the first limiting plate 7 and the second limiting plate 8. A buffer ring 10 and a buffer sleeve 11 are respectively connected inside the placing cylinder 5. There are multiple placing cylinders 5, viewing windows 6, buffer rings 10 and buffer sleeves 11. The multiple placing cylinders 5, viewing windows 6, buffer rings 10 and buffer sleeves 11 are arranged in a rectangular array. The buffer pads 9, buffer rings 10 and buffer sleeves 11 are all made of silicone material. Through the settings of the buffer pads 9, buffer rings 10 and buffer sleeves 11, it is avoided that the displacement of the tool causes friction and collision damage.
[0033] Refer to Figure 2 and Figure 4 In the above-mentioned embodiment, drain ports 12 are provided at the bottoms of both the buffer sleeve 11 and the placing cylinder 5. Since the tool head is placed facing down, the cutting fluid remaining on the surface of the tool head can flow into the drain port 12, and then the cutting fluid passes through the drain port 12 and drops onto the top of the second limiting plate 8. The top of the second limiting plate 8 is in a slope shape, and the cutting fluid is guided away through the slope at the top of the second limiting plate 8 to prevent the cutting fluid from dripping into the lower placing cylinder 5.
[0034] Embodiment Two:
[0035] On the basis of the above-mentioned Embodiment One, in order to prevent the cutting fluid from flowing randomly and soiling the ground, the following settings are made now.
[0036] Refer to Figure 1 and Figure 2, in the above embodiments, a roller 14 is connected to the middle of the top of the counterweight base 1. A plurality of rollers 14 are provided, and the plurality of rollers 14 are equidistantly distributed. The rolling of the rollers 14 reduces the frictional resistance between the collection box 13 and the counterweight base 1, thereby facilitating the staff to pick up and place; a collection box 13 is placed on the top of the roller 14, and the drained cutting fluid falls into the collection box 13; a baffle 15 is fixed to the back of the counterweight base 1, and the collection box 13 abuts against the baffle 15. The collection box 13 is limited by the baffle 15 to prevent the collection box 13 from falling off the back of the counterweight base 1.
[0037] The implementation principle of the present utility model is as follows: First, the staff rotates the adjusting plate 3 downward to tilt the placing cylinder 5. Then, the staff can place the tool with the tool head facing down into the placing cylinder 5. After that, the staff releases the rotating adjusting plate 3, and the torsion spring shaft 4 drives the adjusting plate 3 to reset, so that the placing cylinder 5 abuts against the second limiting plate 8, thereby restoring the adjusting plate 3 and the placing cylinder 5 to a vertical state. At this time, the first limiting plate 7 or the second limiting plate 8 blocks the upper part of the placing cylinder 5 to prevent the tool from falling upward. During storage, due to the settings of the buffer pad 9, the buffer ring 10 and the buffer sleeve 11, it is avoided that the tool is damaged due to friction and collision caused by tool displacement. And because the tool head is placed facing down, the cutting fluid remaining on the surface of the tool head can flow into the drain port 12. Then, the cutting fluid passes through the drain port 12 and drops onto the top of the second limiting plate 8. The cutting fluid is drained away through the slope on the top of the second limiting plate 8 to prevent the cutting fluid from dripping into the placing cylinder 5 below. The drained cutting fluid falls into the collection box 13;
[0038] When it is necessary to clean the collection box 13, the staff only needs to grasp the collection box 13 and pull it out towards the outer surface of the counterweight base 1. At the same time, the rolling of the rollers 14 reduces the frictional resistance between the collection box 13 and the counterweight base 1, thereby facilitating the staff to pick up and place. After dumping, the staff pushes the collection box 13 back above the counterweight base 1, and at the same time, the collection box 13 is limited by the baffle 15 to prevent the collection box 13 from falling off the back of the counterweight base 1;
[0039] When it is necessary to take out the tool later, the staff can view the shape of the tool head through the window 6, so as to facilitate the identification of the type of the tool and avoid taking the wrong one. Then, the staff rotates the adjusting plate 3 downward again to clean the placing cylinder 5. The plurality of placing cylinders 5 respectively place the plurality of tools. When picking up and placing, they will not contact other tools, and the tool head is facing down and located below the placing cylinder 5. When the staff picks up and places, they hold the handle of the tool. Therefore, it is avoided that the staff's hand is scratched by the tool head when taking the tool.
[0040] Although embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and are not limitations thereof. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions, and variations that do not make creative contributions to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
