It can also perform grooving, drilling, reaming, reaming and boring, etc.

[0003] The tool holder device is the most common auxiliary device of CNC lathes. It allows the CNC lathe to complete multiple or even all processing procedures in one clamping of the workpiece, so as to shorten the auxiliary processing time and reduce the errors caused by multiple installations of the workpiece during the processing, thereby improving the processing efficiency and processing accuracy of the machine tool. According to the purpose of use, the tool holder device of the CNC lathe can be divided into two types: storage and processing.

[0004] However, in the prior art, most of the turning tools used in CNC lathes are directly placed on the storage type tool holder device, which not only easily causes the turning tools to collide with each other, causing damage to the turning tools, but also makes the turning tools placed in a messy manner, making it difficult to quickly find the required turning tools, thereby affecting the use effect of the storage type tool holder device. Utility Model Content

[0005] The utility model aims to provide a tool holder device for a numerically controlled lathe to solve the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tool holder device of a CNC lathe, comprising a tool holder body and a guide assembly; wherein the tool holder body comprises a U-shaped frame and a placement plate; a plurality of the placement plates are connected to the U-shaped frame in a linear array through a guide assembly; wherein the guide assembly comprises a placement hole, a guide block and a guide groove; a plurality of placement holes are evenly provided on the placement plate; at least two guide blocks are symmetrically fixed on both sides of the placement plate; at least two guide grooves are symmetrically provided on both sides of the inner wall of the U-shaped frame; wherein the guide block and the guide groove are slidably matched.

[0007] As a preferred embodiment, it further comprises an adjusting mechanism; the adjusting mechanism is arranged on the placing plate.

[0008] As a preferred embodiment, the adjustment mechanism includes a limiting component and a fixing component; wherein the fixing component is arranged on the limiting component.

[0009] As a preferred embodiment, the limiting assembly includes a sliding groove, a sliding block, a spring and a limiting groove; at least two sliding grooves are symmetrically opened on both sides of the placement plate; the sliding block is slidably arranged in the sliding groove, and the end of the sliding block extends to the outside through the sliding groove and the guide block; the two ends of the spring are respectively fixedly connected to the inner wall of the sliding groove and the sliding block; a plurality of limiting grooves are opened in a linear array in the guide groove; wherein, the sliding block is plugged into and matched with the limiting groove.

[0010] As a preferred embodiment, the fixing assembly includes a wedge groove, a screw and an extrusion; a wedge groove is opened on the sliding block; the screw is passed through the placement plate, and the end of the screw extends into the sliding groove; wherein the screw is threadedly connected to the placement plate; and the extrusion is fixedly connected to the end of the screw.

[0011] As a preferred embodiment, the wedge-shaped groove is in a right-angled trapezoidal structure, the dimension of the wedge-shaped groove close to the extrusion piece is smaller than the dimension of the wedge-shaped groove away from the extrusion piece, and the inclined surface of the wedge-shaped groove is arranged away from the spring direction.

[0012] As a preferred embodiment, the extrusion piece is a hemispherical structure, the diameter of the extrusion piece is larger than the diameter of the screw, and the spherical surface of the extrusion piece is in sliding contact with the inclined surface of the wedge groove.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] The tool holder device of the CNC lathe is provided with a guide component. When placing the turning tool for the CNC lathe, the placement plate is first moved according to the size of the turning tool, so that the placement plate is moved and the guide block slides in the guide groove until the placement plate moves to a suitable position. At this time, the turning tool can be placed on the placement hole. Not only can the turning tools for the CNC lathe be placed separately to avoid collision between the turning tools and damage to the turning tools, but the position of the placement plate can also be adjusted according to the length of the turning tool so as to place turning tools of different sizes, thereby greatly improving the applicability of the utility model.

[0015] The tool holder device of the CNC lathe is provided with a sliding groove, a sliding block, a spring and a limit groove. The spring is no longer stressed by a fixing component and begins to shrink, so that the sliding block slides in the sliding groove until the sliding block is out of cooperation with the limit groove. Then, the placement plate is moved until the placement plate is moved to a suitable position. The sliding block is then made to slide in the sliding groove in the opposite direction by the fixing component, so that the spring is stretched by stress until the sliding block is plugged into the limit groove. At this time, the spring returns to its original shape to facilitate fixing the position of the placement plate on the U-shaped frame body, so that the position of the turning tool placed on the placement hole is more stable.

[0016] The tool holder device of the CNC lathe is provided with a wedge-shaped groove, a screw and an extrusion. When it is necessary to adjust the position of the placement plate, the screw is threadedly connected to the placement plate by turning the knob on the screw, and the screw is moved away from the placement plate, so that the spherical surface of the extrusion no longer squeezes the inclined surface of the wedge groove. At this time, the spring is no longer stressed and begins to shrink, causing the sliding block to slide in the sliding groove until the sliding block is disengaged from the limiting groove. When it is necessary to fix the position of the placement plate, the knob on the screw is turned in the opposite direction until the sliding block is plugged into the limiting groove, so that the sliding block can be disengaged from or plugged into the limiting groove through the contact relationship between the spherical surface of the extrusion and the inclined surface of the wedge groove, thereby realizing the adjustment of the position of the placement plate.
