[0041] See also Figure 1-6 , a device for adding two high-speed spindles to a machining center, comprising a mounting frame 1, the mounting frame 1 comprising:

[0042] A pressure adjustment mechanism 5 is arranged on the back of the mounting frame 1;

[0043] A crimping arm 2 mounted on the pressure adjustment mechanism 5; and

[0044] An additional spindle 3 is installed between the mounting frame 1 and the crimping arm 2;

[0045] A pulley 4 is sleeved on a mounting main shaft 3 which is mounted on the mounting frame 1 and passes through the top of the crimping arm 2;

[0046] Wherein, the original spindle 6 located in front of the mounting frame 1 is installed on the machining center; and

[0047] The mounting frame 1 which is drivingly connected to the original spindle 6 is installed on the machining center.

[0048] Among them, the mounting frame 1 includes: a frame body 11 installed on the machining center; a sliding adjustment groove 13 opened on the back of the frame body 11 and accommodating the pressure adjustment mechanism 5 inside; a shaft mounting hole 14 opened on the side of the frame body 11 and accommodating the installation of the spindle 3 through it; a mounting hole 12 opened on the top of the frame body 11 and installed with the machining center through bolts; and a groove 15 opened on the bottom of the frame body 11. The mounting frame 1 is installed on the machining center and is set on the side of the original spindle 6 to cooperate with the operation of the original spindle 6, so that the single-spindle machining center can have the effect of a multi-spindle machining center and improve the machining efficiency of the workpiece.

[0049] Among them, the pressing and adjusting mechanism 5 is slidably connected with the inner wall of the sliding adjustment groove 13, and the sliding adjustment groove 13 is used to limit the sliding condition of the pressing and adjusting mechanism 5. Then, through the sliding ability of the pressing and adjusting mechanism 5, the pressing and adjusting mechanism 5 can drive the crimping arm 2 to press down, and cooperate with the mounting frame 1 to stably install the additional main shaft 3.

[0050] Among them, the pressure adjustment mechanism 5 includes: a slider 51 installed on the crimping arm 2; a screw 52 integrally arranged on the slider 51 and passing through the crimping arm 2; an internal screw hole 53 opened at the bottom of the slider 51; a fixing bolt 54 screwed in the internal screw hole 53; and a strap 55 rotatably sleeved on the fixing bolt 54 and overlapped with the bottom of the mounting frame 1. By setting the screw 52, ​​the crimping arm 2 can be firmly installed on the pressure adjustment mechanism 5 and have sufficient stability. At the same time, the strap 55 is stuck in the strap groove 15 on the mounting frame 1, and the rotation of the fixing bolt 54 is used to pull the slider 51, so that the crimping arm 2 installed on the slider 51 moves downward and cooperates with the mounting frame 1 to clamp and install the main shaft 3.

[0051] Among them, the crimping arm 2 includes: a mounting plate 21 installed on the pressure adjustment mechanism 5; a support arm 22 welded at both ends of the mounting plate 21; and a top shaft hole 23 that is bent and arranged at the top of the support arm 22 and allows the top of the additional spindle 3 to pass through. The crimping arm 2 is provided to support the top position of the additional spindle 3, and cooperates with the mounting frame 1 to keep the additional spindle 3 in a vertical state, and run synchronously with the original spindle 6, thereby achieving the effect of a multi-spindle machining center.

[0052] Among them, the structures on both sides of the mounting frame 1 are symmetrically arranged, and an arc-shaped groove for accommodating part of the original spindle 6 is formed in the middle of the mounting frame 1. The groove in the middle of the mounting frame 1 is fitted with the original spindle 6, so that the added spindles 3 on both sides of the mounting frame 1 form a fixed angle with the original spindle 6, thereby corresponding to the requirements of the workpiece to be processed, completing the processing of three positions at one time, and improving the processing efficiency. At the same time, different models of mounting frames 1 can be changed according to different requirements of the workpiece.

[0053] Working principle: when it is necessary to add a spindle to a single-spindle machining center, first, install the mounting frame 1 on the machining center and make it correspond to the position of the original spindle 6, then slide the pressure adjustment mechanism 5 into the back of the mounting frame 1, and then install the crimping arm 2. After the crimping arm 2 is firmly installed, use the ability of the crimping arm 2 to slide along the pressure adjustment mechanism 5 and the mounting frame 1 to place the additional spindle 3 into the installation position on the mounting frame 1 and the crimping arm 2, and then use the pressure adjustment mechanism 5 to drive the crimping arm 2 to move, so that the additional spindle 3 is firmly installed, and then install the pulley 4 on the top of the additional spindle 3, and provide power for the additional spindle 3 by setting a belt transmission with the original spindle 6.
