Description

Technical Field

[0001] This utility model relates to the field of turret tool holder technology, and in particular to a turret tool holder with an adjustable angle. Background Technology

[0002] A twin-spindle, twin-turret mill-turning compound is a high-performance machining equipment that incorporates twin-spindle and twin-turret technology. A twin-spindle compound is equipped with two spindles arranged opposite each other, which can process two workpieces simultaneously. A twin-turret compound is usually a powered turret, which has multiple tool holder mounting positions to accommodate various tools for different machining needs.

[0003] In traditional power turrets, once the tool holder is fixed to the turret with bolts, the installation angle of the tool holder is fixed. It can only be adapted to cutting operations at a specific angle of the tool body on the tool holder, and it is not convenient to adapt to cutting requirements at multiple angles, resulting in low machining flexibility of the tool body on the tool holder. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a turret tool holder with easily adjustable angles to solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A turret tool holder with adjustable angle, mounted on a turret plate, the turret plate having an end face; the turret tool holder includes:

[0007] The first tool holder is detachably mounted on the end face of the turret plate;

[0008] The second tool holder is connected to the first tool holder via a deflection transmission assembly, allowing the second tool holder on one side of the first tool holder to deflect at a certain angle.

[0009] The rotation transmission component is located inside the first tool holder. By cooperating with the deflection transmission component, the second tool holder can be adjusted to a certain deflection angle.

[0010] Preferably, the first tool holder has a circular cavity and two deflection cavities.

[0011] Preferably, the deflection transmission assembly includes:

[0012] Two deflection plates are rotatably installed in corresponding deflection cavities, and one end of the two deflection plates extending outside the first tool holder is fixedly installed with one side of the second tool holder.

[0013] The connecting rod is rotatably mounted in the first tool holder, and its two ends are respectively fixedly mounted on the side of the two deflection plates that are close to each other;

[0014] The worm gear is fixedly installed in the middle of the connecting rod, and the worm gear is located inside the circular cavity.

[0015] Preferably, the first tool holder has a cylindrical cavity, the cylindrical cavity is connected to another cylindrical cavity, the top sidewall of the cylindrical cavity has a threaded hole, and the bottom sidewall of the cylindrical cavity has a bottom cavity.

[0016] Preferably, the rotational transmission assembly includes:

[0017] The worm has protrusions at both ends, and the protrusions at both ends of the worm are rotatably mounted in a cylindrical cavity; the worm has a rod cavity and the inner wall of the rod cavity has four guide grooves;

[0018] The rotating rod has four rectangular protrusions and one threaded protrusion. The four rectangular protrusions on the rotating rod are slidably installed in the corresponding guide grooves of the worm gear cavity. The threaded protrusion on the rotating rod is threaded into the threaded hole. The top of the rotating rod has a wrench hole.

[0019] Preferably, the second tool holder has multiple seat holes.

[0020] Preferably, the first tool holder has four mounting holes.

[0021] This application utilizes a wrench with a hexagonal protrusion inserted into the wrench hole at the top of a rotating rod to adjust its rotation. This causes the threaded protrusion on the rotating rod to feed into the threaded hole, and the four rectangular protrusions on the rotating rod to rotate and slide upwards or downwards within the corresponding guide grooves of the worm gear. This, in turn, drives the worm gear to rotate within the cylindrical cavity. Under the meshing transmission of the worm wheel and worm gear, the worm wheel and two deflection plates on the connecting rod are driven to rotate, which in turn drives the second tool holder to rotate. This allows for adjustment of the deflection angle of the tool installed in the second tool holder, facilitating the adaptation of the tool installed on the second tool holder to multi-directional cutting requirements, thereby improving the machining flexibility of the tool on the second tool holder.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] To address the issue that traditional power turrets, where the tool holder is bolted to the turret and its fixed angle limits its adaptability to cutting operations at specific angles of the tool body, making it unsuitable for multi-angle cutting and resulting in low machining flexibility for the tool body, this embodiment discloses a turret tool holder with adjustable angle, mounted on the turret plate 100. Figure 1 The first tool holder 200 and the second tool holder 300 shown; and as shown Figure 2 The deflection drive assembly 400 and the rotation drive assembly 500 are shown.

[0032] like Figure 6 As shown, the dual-spindle dual-turret milling and turning compound is equipped with a turret disk 100, which has multiple end faces 101. The first tool holder 200 has four mounting holes 206, which facilitates the use of four bolts to pass through the corresponding mounting holes 206 to fix the first tool holder 200 on the end face 101 of the turret disk 100.

[0033] like Figure 4As shown, the second tool holder 300 is connected to the first tool holder 200 via a deflection transmission assembly 400, allowing the second tool holder 300 on one side of the first tool holder 200 to deflect at a certain angle. For mounting the deflection transmission assembly 400, the first tool holder 200 has a circular cavity 201 and two deflection cavities 202. The deflection transmission assembly 400 is disposed within the circular cavity 201 and the two deflection cavities 202 of the first tool holder 200. The deflection transmission assembly 400 includes two deflection plates 40... 1. Connecting rod 402 and worm gear 403; two deflecting plates 401 are rotatably installed in corresponding deflecting cavities 202, and one end of the two deflecting plates 401 extending outside the first tool holder 200 is fixedly installed with one side of the second tool holder 300; the connecting rod 402 is rotatably installed in the first tool holder 200, and its two ends are fixedly installed on the side of the two deflecting plates 401 that are close to each other; the worm gear 403 is fixedly installed in the middle position of the connecting rod 402, and the worm gear 403 is located in the circular cavity 201.

[0034] like Figure 3 As shown, one side of the second tool holder 300 has multiple seat holes 301, which facilitates the use of multiple bolts to fix the corresponding tool in the second tool holder 300.

[0035] like Figure 4-5As shown, in order for the deflection transmission assembly 400 to adjust the deflection of the second tool holder 300, the first tool holder 200 has a cylindrical cavity 203, which is connected to the cylindrical cavity 201. The top sidewall of the cylindrical cavity 203 has a threaded hole 204, and the bottom sidewall of the cylindrical cavity 203 has a bottom cavity 205. The rotation transmission assembly 500 is disposed in the cylindrical cavity 203 of the first tool holder 200. The rotation transmission assembly 500 includes a worm gear 501 and a rotating rod 502. Both ends of the worm gear 501 have protrusions 5011, and the protrusions 5011 at both ends of the worm gear 501 are rotatably mounted in the cylindrical cavity 203. The worm gear 501 has a rod cavity, and the inner wall of the rod cavity has four guide grooves 5012. The rotating rod 502 has four rectangular protrusions 5021 and one threaded protrusion 5022. The four rectangular protrusions 5021 on the rotating rod 502 are slidably mounted on the worm gear 501. Within the guide groove 5012 corresponding to the upper rod cavity, the threaded protrusion 5022 on the rotating rod 502 is threaded into the threaded hole 204. The top of the rotating rod 502 has a wrench hole 5023. The wrench hole 5023 can be a hexagonal concave hole, which facilitates the insertion of a wrench with a hexagonal protrusion into the wrench hole 5023, allowing the rotating rod 502 to be rotated and adjusted. This causes the threaded protrusion 5022 on the rotating rod 502 to be threaded into the threaded hole 204, causing the four rectangular protrusions 5021 on the rotating rod 502 to rotate and slide upward or downward within the corresponding guide groove 5012 in the worm gear 501. This, in turn, drives the worm gear 501 to rotate within the cylindrical cavity 203, thereby driving the worm wheel 403 and the two deflection plates 401 on the connecting rod 402 to rotate. This, in turn, drives the second tool holder 300 to rotate, thus enabling the adjustment of the deflection angle of the tool installed in the second tool holder 300.

[0036] This application utilizes a wrench with a hexagonal protrusion inserted into the wrench hole 5023 at the top of the rotating rod 502 to rotate and adjust the rotating rod 502. This causes the threaded protrusion 5022 on the rotating rod 502 to feed into the threaded hole 204, and the four rectangular protrusions 5021 on the rotating rod 502 to rotate and slide upward or downward in the corresponding guide grooves 5012 in the worm gear 501. This, in turn, drives the worm gear 501 to rotate in the cylindrical cavity 203. Under the meshing transmission action of the worm wheel 403 and the worm gear 501, the worm wheel 403 and the two deflection plates 401 on the connecting rod 402 are driven to rotate, which in turn drives the second tool holder 300 to rotate. This allows for adjustment of the deflection angle of the tool installed in the second tool holder 300, making it easier for the tool installed on the second tool holder 300 to adapt to multi-directional cutting requirements, thereby improving the flexibility of tool processing on the second tool holder 300.
