Description

Technical Field

[0001] The utility model relates to the technical field of tool carriers, and more specifically, to a numerical control rotary tool carrier. Background Art

[0002] As an auxiliary device widely used in numerical control lathes, the numerical control tool carrier can complete diversified or even all machining processes under the condition of single clamping of the workpiece. This effectively shortens the machining auxiliary time and significantly reduces the errors caused by multiple clamping of the workpiece, thereby improving the machining efficiency and accuracy of the machine tool.

[0003] Chinese Patent CN113751737B discloses a numerical control rotary tool carrier. The fixed top cover adopts a circular structure design. When the turning tool is closely attached and firmly installed on the top cover, if it encounters a large cutting force or external force, the circular top cover is prone to a small position shift due to lack of sufficient stability support, which will affect the positioning accuracy of the tool and the quality of the machined surface, and ultimately have an adverse impact on the overall machining effect. Summary of the Utility Model

The lower plate is connected with the upper plate through the central support block. The top of the lower plate is provided with a lower insertion slot, and the bottom of the upper plate is provided with an upper insertion slot. The upper insertion slot is matched with the lower insertion slot, and a limit slot for inserting a turning tool is formed between the upper insertion slot and the lower insertion slot. A number of locking bolts are threadedly connected to the upper plate, and the locking bolts are directly above the upper insertion slot.

[0007] Furthermore, a number of threaded holes are provided on the upper plate, which penetrate the upper plate, and locking bolts are threadedly connected in the threaded holes.

[0008] Furthermore, an adjusting mechanism is provided between the upper plate and the lower plate.

[0009] Furthermore, the adjusting mechanism includes a fixing plate, on which a number of through holes are provided. Screws are inserted into the through holes. One end of the screw close to the central support block is provided with a left adjusting plate, and a fastening nut is installed on the screw.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. The present utility model will be further described in conjunction with the accompanying drawings and embodiments:

[0019] First Embodiment

[0020] As Figure 1As shown in the figure, a numerically controlled rotary tool rest includes a bottom plate, on which a hollow rotary platform 1 is installed. One side of the hollow rotary platform is connected to a driving motor 2. Both the hollow rotary platform and the driving motor can be purchased externally. For example, the hollow rotary platform can be the model RR80-192W hollow rotary platform of Shenzhen Xinpingtai Transmission Equipment Co., Ltd.

[0021] Above the hollow rotary platform is provided a square tool rest 3, which includes a lower plate 31, a central support block 32 and an upper plate 33. The lower plate is connected to the upper plate through the central support block. At the top of the lower plate is provided a lower insertion slot 311, and at the bottom of the upper plate is provided an upper insertion slot 331. The upper insertion slot cooperates with the lower insertion slot, and a limiting slot for accommodating the turning tool to insert is formed between the upper insertion slot and the lower insertion slot. A number of locking bolts 34 are threadedly connected to the upper plate, and the locking bolts are directly above the upper insertion slot.

[0022] By using the externally purchased hollow rotary platform, the automatic angle adjustment of the square tool rest can be realized. While the cost is controllable, the design of the limiting slot can effectively prevent the turning tool from suffering from large cutting forces or external forces and causing slight position offsets.

[0023] Further, a number of threaded holes are provided on the upper plate, the threaded holes penetrate through the upper plate, and locking bolts are threadedly connected in the threaded holes.

[0024] Working method: Install the numerically controlled rotary tool rest at a suitable position on the machine tool to ensure the stability of the bottom plate. Connect the driving motor 2 to the hollow rotary platform 1 and ensure that all connecting parts are firmly fastened. According to the need, select a suitable turning tool and prepare to install it on the square tool rest 3. Loosen the locking bolts 34 on the upper plate 33, insert the turning tool into the limiting slot, and ensure that the turning tool is stable and in the correct position. Tighten the locking bolts 34 to firmly lock the turning tool on the square tool rest 3. Control the rotation of the hollow rotary platform 1 through the driving motor 2, so as to adjust the square tool rest 3 and the turning tool on it to the required angle. According to the processing requirements, the rotation angle can be precisely adjusted to meet different cutting requirements.

[0025] Second Embodiment

[0026] In some actual working conditions, the shape of the turning tool may not match the shape of the limiting slot. The most appropriate way is naturally to replace the matching square tool rest.

[0027] Another is to set up an adjustment mechanism to compensate for its shape defect.

[0028] As Figure 2 and Figure 3 shown, an adjustment mechanism is provided between the upper plate and the lower plate.

[0029] The adjusting mechanism includes a fixing plate 41, and a plurality of through holes are provided on the fixing plate. A screw rod 43 is inserted into the through holes. A left adjusting plate 42 is provided at one end of the screw rod close to the central support block. A fastening nut 44 is installed on the screw rod. A right adjusting plate 45 is fixedly connected to the central support block through a first bolt 46. By replacing the left and right adjusting plates with different thicknesses, the turning tool can be clamped between the two plates.

[0030] Further, the fastening nut and the left adjusting plate are respectively located on both sides of the fixing plate.

[0031] Further, a countersunk head hole 451 is provided on the left side of the right adjusting plate, and a threaded hole 321 is provided on the central support block at a position matching the countersunk head hole.

[0032] Further, the end of the first bolt passes through the countersunk head hole and is threadedly connected to the threaded hole. At this time, the end of the first bolt is hidden in the countersunk head hole to avoid interference with the clamping of the turning tool.

[0033] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of protection required by the present invention.
