Description

Technical Field

[0001] The utility model relates to the technical field of tool supports for numerical control machine tools, and particularly relates to an auxiliary support device for a tool of a numerical control machine tool. Background Technique

[0002] The numerically controlled lathe is one of the numerically controlled machine tools that are widely used. It is mainly used for the cutting processing 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 the cylindrical and conical threads, etc., and can perform grooving, drilling, reaming, boring, etc. When installing a tool on a numerically controlled machine tool, the tool is usually pressed against the tool rest by means of bolts.

[0003] At present, when a tool of a numerically controlled machine tool is pressed and installed at the tool rest by bolts, the clamping area of some long-shank tools by the bolts is small. When these long-shank tools are sent to the workpiece for processing at the tool rest, the tools are prone to vibrate when stressed, and even some unclamped tools are prone to fall off and fly out when stressed, thus affecting the safe processing of the numerically controlled machine tool. For this reason, we propose an auxiliary support device for a tool of a numerically controlled machine tool. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an auxiliary support device for a tool of a numerically controlled machine tool. A support mechanism is arranged at the tool rest body for fixing the tool of the numerically controlled machine tool and its original upper pressure plate. The support mechanism can form a structure for laterally spinning and pressing the rear shank of the tool outside the upper pressure plate. When the tool of the numerically controlled machine tool is pressed between the upper pressure plate and the tool rest body, the support mechanism can provide lateral support to ensure that the long-shank tool of the numerically controlled machine tool is firmly pressed and installed at the tool rest body for stable numerical control processing. The U-shaped structure of the support mechanism also restricts the tool to ensure that the tool is not easily directly ejected outward after loosening, so that the tool of the numerically controlled machine tool is not easily vibrated and fallen off. And the support mechanism also provides a structure for supporting the tail shank of the tool of the numerically controlled machine tool at the rear, so that there is rear support when the tool of the numerically controlled machine tool is linearly stressed, effectively ensuring that the tool of the numerically controlled machine tool will not loosen backward when contacting the workpiece for processing, and ensuring the stable installation of the tool of the numerically controlled machine tool, and can effectively solve the problems in the background technique.

[0005] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] A tool auxiliary support device for a numerically controlled machine tool, comprising a tool rest body and an upper pressing plate. The upper pressing plate is fixed to the top of the tool rest body, and screw holes are formed on the surface of the upper pressing plate. It further includes a support mechanism. The support mechanism includes a U-shaped clamping plate, a U-shaped convex plate, a side support plate, a rotating support cylinder, a tail abutting plate, a tail rotating cylinder, a rotating column, a abutting disc and a nut. The U-shaped clamping plate is clamped on the surface of the upper pressing plate, and a bolt hole vertically communicating with the screw hole is formed on the long plate body surface of the U-shaped clamping plate. A U-shaped fixed cutting edge is formed through the vertical plate body surface of the U-shaped clamping plate, and a U-shaped convex plate communicating with the U-shaped fixed cutting edge protrudes from the outer surface of the vertical plate body of the U-shaped clamping plate away from the upper pressing plate. A side support plate pressing against the side surface of the upper pressing plate is welded to the side surface of the long plate body of the U-shaped clamping plate, and a rotating support cylinder protrudes outward from the plate body surface of the side support plate. A side rotating hole is formed between the rotating support cylinder and the side support plate. A tail abutting plate is welded to the outer surface of one vertical plate body of the U-shaped clamping plate, and a tail rotating cylinder protrudes outward from the outer surface of the vertical plate body of the tail abutting plate away from the U-shaped clamping plate. A rotating column is rotatably connected between the tail rotating cylinder and the vertical plate body of the tail abutting plate, and an abutting disc for abutting against the tool is welded to one end of the rotating column facing the U-shaped clamping plate.

[0007] Further, a pressing ring is fixed to one end surface of the nut, and a convex rib surface is provided on the outer ring surface of the pressing ring;

[0008] By adopting the above technical solution, the nut with the pressing ring provided with the convex rib surface can be rotatably connected behind the rotating column and pressed against the outside of the tail abutting plate, reducing the force for the rotating column to loosen backward.

[0009] Further, the cylinder body and the plate body of the rotating support cylinder and the side support plate are penetrated by the side rotating hole, and the cavity of the side rotating hole is a threaded hole cavity;

[0010] By adopting the above technical solution, bolts can be rotatably connected at the side rotating holes of the rotating support cylinder and the side support plate, thereby laterally pressing the tool handle pressed and installed between the upper pressing plate and the tool rest body, ensuring that the tool handle is pressed and supported between the upper pressing plate and the tool rest body.

[0011] Further, a threaded tail hole for rotatably connecting the rotating column is formed between the plate bodies of the tail rotating cylinder and the tail abutting plate;

[0012] By adopting the above technical solution, the rotating column can be screwed into the threaded tail hole of the tail rotating cylinder and the tail abutting plate for connection.

[0013] Further, the cavity opening size of the U-shaped fixed cutting edge is the same as the inner plate opening size of the U-shaped convex plate;

[0014] By adopting the above technical solution, the tool handle of the numerically controlled machine tool can be clamped between the U-shaped fixed cutting edge and the U-shaped convex plate, and is not easily ejected outward when the tool is loose, being restricted by the U-shaped fixed cutting edge and the U-shaped convex plate.

[0015] Further, the long plate body of the U-shaped clamping plate presses on the upper plate surface of the upper pressing plate, and the vertical plate bodies of the U-shaped clamping plate are symmetrically clamped outside the vertical plate surfaces of the upper pressing plate;

[0016] By adopting the above technical solution, the U-shaped clamping plate can be better clamped outside the upper pressing plate. Then, the bolt for pressing the tool holder can pass through the bolt hole of the U-shaped clamping plate and then be screwed downward along the screw hole into the tool holder in the tool rest body, and the bolt can also firmly screw the U-shaped clamping plate onto the upper pressing plate.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model is provided with a support mechanism at the tool rest body for fixing the tool of the numerical control machine tool and its original upper pressing plate. The support mechanism can form a structure for laterally spinning and pressing the rear handle body of the tool outside the upper pressing plate. When the tool of the numerical control machine tool is pressed between the upper pressing plate and the tool rest body, the support mechanism can provide lateral support to ensure that the long-shank tool of the numerical control machine tool is firmly pressed and installed at the tool rest body for stable numerical control machining, so that the tool of the numerical control machine tool is not prone to vibration and falling off;

[0019] And the support mechanism also provides a structure for supporting the tail handle of the tool of the numerical control machine tool at the rear, so that there is rear support when the tool of the numerical control machine tool is linearly stressed, effectively ensuring that the tool of the numerical control machine tool will not loosen backward when contacting the workpiece for machining, and ensuring the stable installation of the tool of the numerical control machine tool.

[0025] Such as Figures 1-3As shown in the figure, a tool auxiliary support device for a numerically controlled machine tool includes a tool rest body 1 and an upper pressing plate 2. The upper pressing plate 2 is fixed to the top of the tool rest body 1, and screw holes 3 are provided on the surface of the upper pressing plate 2. It further includes a support mechanism 4.

The U-shaped clamping plate 5 is clamped on the surface of the upper pressing plate 2, and bolt through holes 6 vertically communicating with the screw holes 3 are provided on the long plate body surface of the U-shaped clamping plate 5. A U-shaped fixed cutting edge 7 is penetrated through the vertical plate body surface of the U-shaped clamping plate 5, and a U-shaped convex plate 8 communicating with the U-shaped fixed cutting edge 7 protrudes from the outer surface of the vertical plate body of the U-shaped clamping plate 5 away from the upper pressing plate 2. A side support plate 9 pressing against the side surface of the upper pressing plate 2 is welded to the side of the long plate body of the U-shaped clamping plate 5, and a rotating support cylinder 10 protrudes outward from the plate body surface of the side support plate 9. A side rotation hole is provided between the rotating support cylinder 10 and the side support plate 9. A tail abutting plate 11 is welded to the outer surface of one vertical plate body of the U-shaped clamping plate 5, and a tail rotating cylinder 12 protrudes outward from the outer surface of the vertical plate body of the tail abutting plate 11 away from the U-shaped clamping plate 5. A rotating column 13 is rotatably connected between the tail rotating cylinder 12 and the vertical plate body of the tail abutting plate 11, and a pressing disc 14 for abutting against the tool is welded to one end of the rotating column 13 facing the U-shaped clamping plate 5. A nut 15 is rotatably connected to the outer column of the rotating column 13 away from the pressing disc 14 and the tail abutting plate 11.

[0026] Wherein, a pressing ring 16 is fixed to one end surface of the nut 15, and a convex rib surface is provided on the outer ring surface of the pressing ring 16;

[0027] By adopting the above technical solution, the nut 15 with the pressing ring 16 provided with a convex rib surface can be rotatably connected behind the rotating column 13 and pressed against the outside of the tail abutting plate 11 to slow down the force for the rotating column 13 to loosen backward.

[0028] Wherein, the cylinder body and the plate body of the rotating support cylinder 10 and the side support plate 9 are penetrated by the side rotation hole, and the cavity of the side rotation hole is a threaded hole cavity;

[0029] By adopting the above technical solution, bolts can be rotatably connected at the side rotation holes of the rotating support cylinder 10 and the side support plate 9, so as to laterally press the tool handle pressed between the upper pressing plate 2 and the tool rest body 1 to ensure that the tool handle is pressed and supported between the upper pressing plate 2 and the tool rest body 1.

[0030] Wherein, a threaded tail hole for rotatably connecting the rotating column 13 is provided between the plate bodies of the tail rotating cylinder 12 and the tail abutting plate 11;

[0031] By adopting the above technical solution, the rotating column 13 can be screwed into the threaded tail hole of the tail rotating cylinder 12 and the tail abutting plate 11 for connection.

[0032] Wherein, the cavity size of the U-shaped fixed cutting edge 7 is the same as the inner plate opening size of the U-shaped convex plate 8;

[0033] By adopting the above technical solution, the handle of the CNC machine tool cutter can be clamped between the U-shaped fixed cutting edge 7 and the U-shaped convex plate 8, and when the cutter is loose, it is restricted by the U-shaped fixed cutting edge 7 and the U-shaped convex plate 8 and is not likely to fly outwards.

[0034] Among them, the long plate body of the U-shaped clamping plate 5 presses on the upper plate surface of the upper pressing plate 2, and the vertical plate bodies of the U-shaped clamping plate 5 are symmetrically clamped outside the vertical plate surfaces of the upper pressing plate 2;

[0035] By adopting the above technical solution, the U-shaped clamping plate 5 can be better clamped outside the upper pressing plate 2. Then, the bolt for pressing the cutter handle can pass through the bolt hole 6 of the U-shaped clamping plate 5 and then be screwed down along the screw hole 3 to press the cutter handle in the tool rest body 1, and the bolt can also firmly press the U-shaped clamping plate 5 at the upper pressing plate 2.

[0036] It should be noted that the present utility model is an auxiliary support device for a CNC machine tool cutter. A support mechanism 4 is provided at the tool rest body 1 for fixing the CNC machine tool cutter and its original upper pressing plate 2. The U-shaped clamping plate 5 of the support mechanism 4 can be better clamped outside the upper pressing plate 2. Then, the worker inserts the cutter handle of the cutter along the U-shaped fixed cutting edge 7 from inside the U-shaped convex plate 8 between the upper pressing plate 2 and the tool rest body 1, and the rear handle rod of the cutter handle can extend backward from another group of U-shaped convex plates 8. Then, the bolt for pressing the cutter handle can pass through the bolt hole 6 of the U-shaped clamping plate 5 and then be screwed down along the screw hole 3 to press the cutter handle in the tool rest body 1. At the same time, the bolt can also firmly press the U-shaped clamping plate 5 at the upper pressing plate 2. Then, rotate the rotating column 13 at the tail rotating cylinder 12 of the tail abutting plate 11, so that the rotating column 13 drives the abutting disc 14 to contact the tail of the cutter handle to provide support. Then, the nut 15 drives the pressing ring 16 to rotate and abut against the tail abutting plate 11 at the rotating column 13, so that the pressing ring 16 tightly abuts against the outer surface of the tail abutting plate 11. When the CNC machine tool cutter moves forward for workpiece processing and is stressed, the tail of the long cutter handle of the cutter is abutted by the abutting disc 14 and is not likely to vibrate, and the side of the long cutter handle of the cutter is laterally abutted, ensuring that the CNC machine tool cutter is stably installed at the tool rest body 1. Unscrew the bolt at the side support plate 9 and the rotating support cylinder 10, and then rotate the nut 15 backward to rotate the rotating column 13 away from the cutter handle. Then, screw out the bolt above the U-shaped clamping plate 5 outward. At this time, the cutter can be removed from the tool rest body 1.
