Background technique

The turret tool post is usually used in the existing CNC turning process. Although more tools can be installed to meet the needs of complex parts processing, the tool post must be moved to a tool change point far away from the processed part when changing the tool. The middle turret moves in an empty stroke and cannot be processed, and it takes a certain amount of time to change and lock the turret turret, which is not conducive to improving the efficiency of CNC machining, saving processing time, and reducing manufacturing costs. At the same time, due to its tool change The structure and process are fixed. No matter how simple the parts are processed, such a complicated program is required, which has poor adaptability and further increases the cost of use.

In view of the above problems, it is necessary to propose a tool holder with a new structure, which has the advantages of simple structure, quick tool change, convenient assembly, improved processing efficiency and reduced manufacturing cost.

Contents of the invention

In view of this, the purpose of this utility model is to provide a movable combined tool holder to solve the problem of high manufacturing cost due to low tool change efficiency in the prior art, and insufficient adaptability and cost of use due to fixed tool holder structure and tool change process. high question.

In order to achieve the above object, the utility model provides the following technical solutions:

A movable combined tool holder, comprising a bottom plate and at least one movable knife seat detachably fixed on the bottom plate, the movable knife seat is provided with a plurality of tool fixing positions and is arranged at the tool fixing positions for A clamping device for clamping and fixing the tool.

Further, the tool fixing position is a plurality of square grooves penetrating through the movable tool seat.

Further, the movable knife seat is a square cylinder, and two square grooves are provided in parallel on any corresponding side of the square cylinder.

Further, the square groove has a tool loading opening extending outward along the movable tool seat.

Further, the pressing device is a bolt or a screw screwed on the movable tool seat.

Further, both the base plate and the movable knife seat are provided with a knife relief position.

The beneficial effects of the utility model are:

The utility model can be freely combined on the bottom plate according to the processing needs through the bottom plate and the movable tool seat that can fix multiple tool seats, so as to realize different processing requirements and improve its adaptability; at the same time, after each tool is set, it can be Direct tool change processing, less tool idle travel distance, no tool holder turret tool change and locking process, saving processing time, improving processing efficiency, and reducing manufacturing costs to a certain extent.

Other advantages, objectives and features of the present utility model will be set forth in the following description to some extent, and to some extent, based on the investigation and research below, it will be obvious to those skilled in the art, or can be Get teaching from the practice of the utility model. The objectives and other advantages of the utility model can be realized and obtained through the following description.

In order to make the purpose, technical solutions and beneficial effects of the utility model clearer, the utility model provides the following drawings for illustration:

Fig. 1 is the structural representation of the utility model first embodiment;

Fig. 2 is the structural representation of the second embodiment of the utility model;

Fig. 3 is a schematic structural diagram of a third embodiment of the present invention.

detailed description

The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

first embodiment

As shown in Fig. 1, a kind of movable combination tool holder in the present embodiment comprises base plate 1, is provided with a plurality of threaded hole groups on the base plate, can fix a plurality of movable tool holders 2, at the same time, on the movable tool holder 2 A plurality of tool fixing positions 3 are provided, and a pressing device for clamping and fixing the tool 6 is arranged at the tool fixing positions 3. In this embodiment, a movable tool holder 1 is installed, which is suitable for processing simple parts. Tightening device can be various prior art, as hydraulic cylinder, air cylinder or electric push rod, and present embodiment is bolt or screw 4, and it is simple, and cost is low, and the tool fixing position 3 of present embodiment is a plurality of penetratingly arranged on movable The square groove on the knife seat, the bolt or screw 4 is fixed on the movable knife seat 2 through the threaded hole above the square groove on the movable knife seat. When the tool is installed, tighten the bolt or screw 4 to lock the tool. , the present embodiment is also provided with a tool relief position 5 on the bottom plate and the movable tool seat. The tool relief position of this embodiment is a gap located at one end of the square groove. Making full use of the gap can avoid interference between the tool and the part during the processing process, affecting the processing quality and cause security problems.

When in use, the tool rest is directly fixed on the lathe base, the tool is installed according to the processing needs, and the processing operation can be performed after the tool setting is completed. The structure is simple and the operation is convenient.

As an improvement of this embodiment, the movable knife seat is a square cylinder, and two square grooves are arranged in parallel on any corresponding side of the square cylinder. Since they are arranged in parallel on a pair of side surfaces, the length of the movable tool seat can be fully utilized to avoid machining interference, which is beneficial to reducing the length of the movable tool seat, reducing material waste and use cost.

As an improvement of this embodiment, the square groove has a tool loading opening 7 extending outward along the movable tool seat, through which the tool can be loaded from its cross-sectional direction instead of from its axial direction. , so that the loading is quick and convenient, which is beneficial to shorten the operation time.

second embodiment

As shown in Figure 2, it is a schematic structural diagram of the second embodiment. The difference from the first embodiment is that two movable tool seats are arranged side by side on the side of the bottom plate 1, which can increase the number of tools and improve its processing adaptability.

third embodiment

As shown in Figure 3, it is a schematic structural diagram of the third embodiment. The difference from the second embodiment is that the other side of the bottom plate 1 is also provided with a movable knife seat 2, and the movable knife seat 2 on this side is rotated by 90 degrees to allow internal The boring process of the hole further increases the number of tools and processing procedures, and improves its processing adaptability. At the same time, it only needs to move horizontally to realize tool change on the same side or different sides.

Since multiple movable tool holders can be fixed on the bottom plate, according to different processing parts, the corresponding number of movable tool holders can be installed to meet different processing needs and improve its adaptability; at the same time, after each tool is set, it can be directly replaced. Tool processing, the tool has less empty travel distance, no tool holder turret tool change and locking process, saves processing time, improves processing efficiency, reduces manufacturing costs to a certain extent, and improves competitiveness.

Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that it can be described in the form Various changes can be made in the above and in the details without departing from the scope defined by the claims of the present invention.
