[0029] Such as Figures 1-4As shown in the figure, an embodiment of a machine tool for machining the inner side of a groove according to the present utility model includes a machine table 1. One end of the machine table 1 is embedded with a first servo motor 2, the first servo motor 2 is connected to a first ball screw 3, a workpiece fixture 14 is arranged on the first ball screw 3, the other end of the first ball screw 3 is fixed on a first bearing block 13, and a spindle box 5 cooperating with the workpiece fixture 14 is arranged at the other end of the machine table 1. Among them, the spindle box 5 is fixedly installed on the machine table 1 through a locking screw 51;

[0030] See details Figure 1 and 2 On the machine table 1, there is a workpiece fixture 14 that can reciprocate left and right. The workpiece fixture 14 includes a moving seat 144 arranged on the first ball screw 3. A moving platform 145 that can move back and forth is arranged on the moving seat 144. A clamping block 146 is arranged on the moving platform 145. An adjusting screw 147 is inserted through the clamping block 146. The workpiece to be processed is adjusted by the adjusting screw 147 to control its clamping degree in the clamping block 146. A second servo motor 141 is embedded and installed inside one end of the moving seat 144. One end of the second servo motor 141 is connected to a second ball screw 142. Through the cooperation of the second servo motor 141 and the second ball screw 142, the moving seat 144 is driven to move. The moving platform 145 is installed on the second ball screw 142, and the other end of the second ball screw 142 is installed in a second bearing block 143 of the moving seat 144;

[0031] When in use, the workpiece fixture 14 clamps the workpiece to be processed and controls its forward and backward movement or positioning. The workpiece fixture 14 cooperates with at least two or more sets of combined cutter heads on the spindle box 5. Two grinding blades 112 are arranged on each set of combined cutter heads, and the accuracies of the grinding blades 112 in different groups are different. In order to better explain the principle, two sets of combined cutter heads are provided in this solution. Specifically: Two sets of combined cutter heads are arranged on the spindle box 5. The two sets of combined cutter heads include a first combined cutter head 11 for rough machining and a second combined cutter head 12 for finish machining. The structure of the second combined cutter head 12 is the same as that of the first combined cutter head 11. The first combined cutter head 11 includes a connecting disk 111. Grinding blades 112 are arranged on both the front and back sides of the connecting disk 111. The distance between the two grinding blades 112 on the first combined cutter head 11 is the distance between two opposite machining surfaces on the inner side of the groove of the workpiece to be processed. The two grinding blades 112 are coaxially arranged, and a mating gear 113 for driving the two grinding blades 112 to rotate is arranged in the middle. In the machining process, the machining sequence is from rough to fine. Therefore, the workpiece to be processed on the workpiece fixture 14 is first ground by the two grinding blades 112 on the first combined cutter head 11 and then ground by the two grinding blades 112 on the second combined cutter head 12;

[0032] To achieve the rotation of the grinding blade 112, a driving motor 4 is provided at the bottom of the main spindle box 5. The driving motor 4 has a first pulley externally connected to it, and the first pulley is connected to a second pulley 6 on the main spindle box 5. A first gear 8 is provided on a first rotating shaft 7 where the second pulley 6 is located, and the first gear 8 meshes with a mating gear 113 coaxial with the grinding blade 112. In addition, to achieve multi-stage cooperation and make the rotation more precise, a second rotating shaft 9 is further provided on the main spindle box 5. The second rotating shaft 9 is arranged inside the first rotating shaft 7 where it is located. A second gear 10 is installed on the second rotating shaft 9. The second gear 10 is arranged between the first gear 8 and the combined cutter head. The second gear 10 meshes with the first gear 8 and the mating gear 113 coaxial with the grinding blade 112 respectively, realizing the step-by-step transmission of rotation. And it is not limited to only two-stage linkage transmission. Multiple gears for meshing can also be set, such as a third gear, a fourth gear, etc. (not shown in the figure), so as to finally achieve the precise rotation of the grinding blade 112.

[0033] When the present utility model is in use, the first servo motor drives the first ball screw to rotate. The rotation of the first ball screw drives the moving seat to approach or move away from the main spindle box. First, the workpiece to be processed is installed on the clamping block, and the adjusting screw on the clamping block is used to tightly fix the workpiece to be processed. Then, the first servo motor is started to drive the moving seat to move. At this time, the main spindle box is also started synchronously. The driving motor below the main spindle box drives the pulley to rotate. The rotation between the two pulleys drives the first rotating shaft to rotate. The first gear on the first rotating shaft meshes with the second gear on the second rotating shaft. The second gear on the second rotating shaft meshes with the mating gear on the first combined cutter head, thereby driving the rotating shaft of the mating gear to rotate. The two grinding blades coaxial with the mating gear rotate accordingly. The two grinding blades respectively grind one side surface, so as to simultaneously machine both sides inside the groove of the workpiece sent. When the rough machining of this surface is completed, the first servo motor is adjusted to drive the moving seat to move outwards. Then, the second servo motor is adjusted to drive the moving platform to move backwards to change the machining area. Finally, the first servo motor is adjusted to drive the moving seat to move inwards to cooperate with the second combined cutter head to achieve the effect of double-sided finish machining inside the groove. Such an operation method can avoid repeatedly disassembling and assembling the workpiece, making the machining more coherent and reducing the quality problems caused by repositioning.
