According to the flap-type workbench of the machine tool, it is characterized in that: there are four vertical positioning devices for the flap-type workbench provided on the flap-type worktable, which are respectively arranged on both sides of the upper and lower parts of the flap-type worktable; There are 4 rotating clamps, which are respectively installed corresponding to the vertical positioning device of the flap workbench; the number of safety bolts is 2, which are respectively corresponding to the vertical positioning device of the flap workbench installed on the upper part of the flap workbench Install.

According to the above-mentioned turnover table of the machine tool, it is characterized in that: the end of the screw is provided with a buffer disc spring.

The turnover table of the machine tool of the utility model can be turned from a horizontal state to a vertical state and accurately positioned. The workpiece can be positioned and clamped in a horizontal state, and then turned to a vertical state by power such as a screw or a hydraulic cylinder. The unique positioning and clamping mechanism fixes the workbench and completes parts processing in the vertical position. This kind of workbench is combined with the horizontal machining center with the layout of the horizontal spindle to form a horizontal machining center with flaps, which is especially suitable for high-speed and high-efficiency milling machine tools. The secondary thermal deformation and secondary cutting can improve the service life of the tool, and at the same time, it is easy to realize the fully enclosed design of the cutting processing work area, which improves the protection level of equipment and personnel. The utility model takes into account the advantages of convenient clamping of vertical processing parts and convenient chip removal for horizontal processing, and improves work efficiency.

In the attached drawings: 1. Support frame of the flap workbench; 2. Safety bolt; 3. Rotary clamp; 4. Lead screw nut pair; 5. Turnover workbench; , The vertical positioning device of the flap table; 8, the safety bolt cylinder; 9, the buffer disc spring.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:

As shown in Figure 1, Figure 2, Figure 3, Figure 4, Figure 5 and Figure 6, the utility model machine tool turnover table is mainly composed of a support frame 1, a safety bolt 2, a rotary clamp 3, a wire Bar nut pair 4, flap workbench 5, flap workbench overturn support rotating shaft 6, flap workbench vertical positioning device 7, safety bolt cylinder 8, buffer disc spring 9 etc. form.

The support frame 1 of the turnover table is fixed on the foundation, and the support shaft 6 of the turnover table 5 is rotatably installed on the support frame 1 of the turnover table through the flipping work table; The support frame 1 and the flap workbench 5 are connected, and the flap workbench 5 is driven by the lead screw nut pair 4, the nut rotates, and the lead screw moves; On the support frame 1 of the panel workbench, a rotary clamp 3 and a safety bolt 2 are installed corresponding to the vertical positioning device 7 of the turnover panel workbench. The safety bolt 2 is connected with the safety bolt cylinder 8. On the table support frame 1.

There are 4 vertical positioning devices 7 for the turnover table 5 arranged on the top and bottom sides of the top and bottom of the turnover table 5; Plate workbench vertical positioning device 7 is correspondingly installed; Described safety bolt 2 is 2, is installed in the turnover plate workbench vertical positioning device 7 corresponding installation of flap workbench 5 tops respectively. The end of the lead screw is provided with a buffer disc spring 9 .

The turnover table 5 of the utility model is driven by the screw nut pair (the nut rotates, the screw moves), and the conversion between the horizontal state and the vertical state is realized. The turnover of the turnover table of the utility model is mainly driven synchronously by double screws, Its power transmission mode is: servo motor drive, planetary gear train, gear pair, rotary screw pair.

In the vertical state, the rotating shaft 6 and the vertical positioning device 7 of the turnover table are precisely positioned by turning over the turnover table, and the rotary clamp 3 is clamped; the safety bolt 2 is locked and disengaged through the safety bolt cylinder 8 ( See Figure 3); while the rotary clamp 3 moves axially, it can realize 90° rotation to realize the clamping and loosening of the turnover table (see Figure 5); the safety bolt 2 prevents the turnover table 5 from accidentally turning over; The rotary clamp is clamped, and the safety bolt is closed by the safety bolt cylinder 8, at this time, the parts can be processed. Before turning the flap table from the vertical position to the horizontal position, the safety bolt 2 needs to be opened by the safety bolt cylinder 8, and the rotating clamp 3 is loosened. Only then can the flap table be turned from the vertical position to the horizontal position. Carry out overturning, after overturning to the horizontal position, carry out the loading and unloading of parts. When the flap table is in the horizontal position, the buffer disc spring 9 at the end of the screw is compressed to the maximum value, and released when it is in the vertical position, so as to avoid mechanical damage caused by the continued movement of the screw after the flap table is flipped in place.

The above-mentioned embodiment is only to describe the preferred implementation of the present utility model, not to limit the design and protection scope of the present utility model. Various modifications and improvements made in the technical solution of the utility model shall fall within the scope of protection of the utility model.
