Description

Technical Field

[0001] This utility model relates to the field of power tool holder technology, specifically a power tool holder fixing structure. Background Technology

[0002] A powered tool holder refers to a tool holder that is mounted on a powered tool turret and can be driven by a servo motor. This type of tool holder is generally used on mill-turn machines, and a few can also be used on machining centers with powered tool turrets.

[0003] For example, the Chinese authorized patent (Power Tool Holder) with publication number CN206047189U includes a tool holder body, a motor, and a milling cutter disc. The tool holder body has a power transmission end and a pivot connection end. The power transmission end is connected to the motor, and the pivot connection end moves synchronously with the power transmission end. The milling cutter disc is mounted on the end face of the pivot connection end and has several milling cutter mounting positions distributed along a circular trajectory. The rotation axis of the pivot connection end passes through the center of the circular trajectory. This power tool holder can simultaneously mount multiple milling cutters. During thread or helical machining, the pivot connection end can simultaneously drive multiple milling cutters to move synchronously, thereby significantly improving the efficiency of part machining and shortening the machining time.

[0004] However, most existing power tool holders use a single bolt to fix the connecting seat and base. Over time, the bolt is prone to loosening due to vibration, which affects the stability of use. Therefore, this does not meet the current requirements. To address this, we propose a power tool holder fixing structure. Utility Model Content

[0005] The purpose of this utility model is to provide a power tool holder fixing structure to solve the problem mentioned in the background art that most of the existing power tool holders are fixed by a single bolt. After long-term use, the bolt is prone to loosening due to vibration, which affects the stability of use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power tool holder fixing structure, comprising: a connecting seat, a connecting plate at the lower end of the connecting seat, a base at the lower end of the connecting plate, safety grooves at the corners of the base, a second fixing bolt inserted into the safety groove, and one end of the second fixing bolt passing through the safety groove and threadedly connected to the connecting plate, and reinforcement components on both sides of the connecting plate.

[0007] Preferably, the reinforcement component includes a mounting base, and a pressing seat is provided on one side surface of the top of the mounting base. The pressing seat is welded and fixed to the mounting base. The lower surface of the pressing seat presses on the upper surface of the connecting plate, and the lower surface of the mounting base presses on the upper surface of the base.

[0008] Preferably, the reinforcement component further includes a triangular limiting plate, which is located at the upper end of the mounting base. A first bolt groove is provided on the upper surface of one end of the triangular limiting plate and the upper surface of the mounting base. A second bolt groove is provided on the upper surface of the bent part of the triangular limiting plate and the upper surface of the lower pressure seat. The first bolt groove passes through the triangular limiting plate and the mounting base, and the second bolt groove passes through the triangular limiting plate and the lower pressure seat.

[0009] Preferably, a first hexagonal bolt is inserted into the first bolt slot, and one end of the first hexagonal bolt passes through the triangular limiting plate and the mounting seat and is threaded to the base. A second hexagonal bolt is inserted into the second bolt slot, and one end of the second hexagonal bolt passes through the triangular limiting plate and the lower pressure seat and is threaded to the connecting plate.

[0010] Preferably, the other two ends of the triangular limiting plate are respectively provided with a first through hole and a second through hole, and the first through hole and the second through hole have the same structure. The first through hole and the second through hole both penetrate the triangular limiting plate, and the other two ends of the triangular limiting plate are sleeved on the outside of the two second fixing bolts through the first through hole and the second through hole.

[0011] Preferably, a fixing nut is provided at the lower end of both the first through hole and the second through hole, and the fixing nut is threadedly connected to the second fixing bolt.

[0012] Preferably, an adjustment groove is provided on one side of the safety groove, a first fixing bolt is inserted into the adjustment groove, and one end of the first fixing bolt passes through the adjustment groove and is threadedly connected to the connecting plate.

[0013] Preferably, the first fixing bolt moves along the adjusting groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) This utility model provides reinforcement components on both sides of the connecting plate. When installing the reinforcement components, the two mounting seats and the pressure seat are placed on both sides of the connection between the connecting plate and the base. The fixing nut is threaded to the second fixing bolt, which stabilizes the second fixing bolt. Then, the triangular limiting plate is placed on the upper end of the mounting seat, and the other two ends of the triangular limiting plate are sleeved on the outside of the two second fixing bolts through the first through hole and the second through hole, which presses down on the fixing nut. The triangular limiting plate is fixed by the first hexagonal bolt and the second hexagonal bolt, which also presses down on the fixing nut to prevent vibration from loosening. This also prevents the second fixing bolt from loosening, improves the stability of the connection plate and the base, and solves the problem that most of the existing power tool holders are fixed by a single bolt. After long-term use, the bolt is easy to loosen due to vibration, which affects the stability of use.

[0016] (2) By setting an adjustment groove on one side of the safety groove, one end of the first fixing bolt passes through the adjustment groove and is threaded to the connecting plate, and then one end of the second fixing bolt passes through the safety groove and is threaded to the connecting plate. The connection between the connecting plate and the base is fixed by the first fixing bolt and the second fixing bolt, thereby improving stability and safety. Attached Figure Description
