Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a tool clamp device for machine tools. Background Art

[0002] A machine tool refers to a machine used to manufacture machines, also known as a machine tool or machine tool. It is usually referred to as a machine tool. It is generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools. The turning tool is installed on the machine tool. In order to achieve precise processing, the position of the turning tool needs to be adjusted subsequently.

[0003] Some existing equipment on the market generally uses a screw to adjust the height of the placement table in a controllable manner, and then the placement table can be adjusted to a suitable height with the help of a scale, so that the turning tool can be installed at a suitable height, and the adjustment is more accurate and fast. The placement table can be made more stable during movement and adjustment through the vertical rod, and at the same time, the placement table can more stably support and clamp the turning tool.

[0004] However, in actual use, when installing some shorter turning tools on the above-mentioned equipment, the tail end of the turning tool cannot be tightly pressed, which can easily cause the entire turning tool to tilt, resulting in the inability to guarantee the accuracy of the produced parts. In view of this, we propose a tool clamp device for machine tools. Utility Model Content

[0005] The purpose of the present utility model is to provide a tool holder device for a machine tool to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a tool holder device for a machine tool, comprising a mounting seat, a through hole is provided on the upper surface of the mounting seat, a turning tool is provided on the upper surface of the mounting seat, a threaded column is sleeved inside the through hole, a nut is sleeved on the arcuate surface of the threaded column, a tightening device is provided on one side of the mounting seat, the tightening device includes a mounting piece, a mounting piece is provided on one side of the mounting seat, a screw rod is rotatably connected to one side of the mounting piece, and a threaded column is rotatably connected to the upper surface of the mounting piece. The bottom of the mounting piece is rotatably connected to a threaded column three, the arc surface of the threaded column two is sleeved with a spring one, the arc surface of the threaded column two is sleeved with an upper clamping piece, the arc surface of the threaded column two is sleeved with a nut two, the arc surface of the threaded column three is sleeved with a spring two, the arc surface of the threaded column three is sleeved with a lower clamping piece, and the arc surface of the threaded column three is sleeved with a nut three. One end of the screw rod is fixedly connected to a rotating block, and the other end of the screw rod is rotatably connected to a pressing block. The setting of the pressing block can keep one side of the turning tool stable.

[0007] Preferably, a slot is provided on the lower surface of the upper clamping member, and the slot is adapted to the shape of one side of the mounting seat. The upper clamping member is positioned between nut 2 and spring 1, which allows nut 2 to better adjust the upper clamping member.

[0008] Preferably, a slot is provided on the upper surface of the lower clamping member, and the slot is adapted to the slot provided on the bottom of the upper clamping member. The position of the lower clamping member is between nut three and spring two, which enables nut three to better adjust the lower clamping member.

[0009] Preferably, there are two mounting seats, which are symmetrically arranged at the center of the threaded column. The size of the mounting seats is adapted to the size of the upper clamping member, the mounting member and the lower clamping member, which allows the upper clamping member, the mounting member and the lower clamping member to be better used.

[0010] Preferably, a groove is provided on the upper surface of the mounting seat, and an anti-slip layer is provided on one side of the inner wall of the groove, which can prevent the turning tool from sliding easily.

[0011] Preferably, a turning tool is provided inside the groove, and the size of the groove is adapted to the size of the turning tool, which can enable the turning tool to be better positioned.

[0012] Compared with the prior art, the present invention provides a tool holder device for a machine tool, which has the following beneficial effects:

[0013] 1. The tool clamp device for a machine tool is provided with an upper clamping part, a mounting part, a lower clamping part, a second threaded column, a second nut, a first spring, a second spring, a third threaded column, a third nut, a screw rod, a rotating block and a pressing block in order to prevent the entire turning tool from being skewed when installing some shorter turning tools. This can enable the rotating block to rotate the screw rod when installing some shorter turning tools, so that the pressing block can be moved forward and pressed against the shorter turning tool, so that the turning tool can be kept stable during installation.

[0014] 2. The tool holder device for the machine tool can prevent the turning tool from being difficult to install and position during installation by providing a groove and an anti-slip layer so that the turning tool can be placed inside the groove. The anti-slip layer is provided on the inner wall of the groove, and the anti-slip layer is provided in a rack shape, so that the anti-slip layer can increase the friction when contacting with both sides of the turning tool, so that the turning tool can be positioned and installed more conveniently during installation and the turning tool is not easy to slip when in use.
