[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the utility model provides a technical solution: a milling machine for automobile inspection tool processing, comprising a base 1 and a moving assembly 2, a milling mechanism 11 and a support seat 12 are installed on the top of the base 1, and a connecting platform 13 is installed on the top of the supporting seat 12, a workbench 14 is slidably installed on the top of the connecting platform 13 through the moving assembly 2, the moving assembly 2 comprises two groups of mounting grooves 21 and a motor 23, the two groups of mounting grooves 21 are respectively opened on both sides of the top of the connecting platform 13, one side of the two groups of mounting grooves 21 are rotatably installed with gears 22, the gears 22 are installed at a position close to the side end opening of the mounting groove 21, the motor 23 is installed on the outer wall of the connecting platform 13, the output end of the motor 23 is connected to one of the groups of gears 22, and the two groups of gears 2 2 are meshed with racks 24, and the racks 24 are fixedly connected to the bottom of the workbench 14, the racks 24 slide in the mounting groove 21, and a connecting rod 25 is connected between the two sets of gears 22. This structure allows the workbench 14 to be moved, so that when placing and removing the workpiece, it can be kept away from the engraving and milling mechanism 11, reducing the possibility of danger caused by the worker's head hitting the engraving and milling mechanism 11. A T-slot 15 is opened in the middle position of the top of the connecting table 13, and a T-bar 16 is fixedly connected to the middle position of the bottom of the workbench 14, and the T-bar 16 is slidably inserted in the T-slot 15, so that the workbench 14 moves more stably at the top of the connecting table 13, and at the same time, it can support the workbench 14 moved to one side of the connecting table 13.

[0023] As an implementation method in this embodiment, Figure 3 , Figure 4 and Figure 5 As shown, a fixing mechanism for fixing the workpiece is installed on the upper side of the workbench 14, and the fixing mechanism includes a clamping assembly 3 for clamping the workpiece and a pressing assembly 4 for pressing the workpiece. The clamping assembly 3 includes a movable groove 31 and a motor 2 32. The movable groove 31 is opened on one side of the top of the workbench 14, so that the movable groove 31 can avoid the middle position of the top of the workbench 14, so that the workpiece can be better engraved and milled. The motor 2 32 is installed at the side end of the workbench 14, and the output end of the motor 2 32 extends to the movable groove 31 and is connected to a bidirectional screw 33, and the surface of the bidirectional screw 33 Both sides of the device are threaded with screw sleeves 34, and the tops of the two groups of screw sleeves 34 are fixedly connected with clamping plates 35. The pressing assembly 4 is installed on the top of the clamping plate 35. This structure makes it possible to clamp the workpiece placed on the top of the workbench 14, making the processing placement more stable, greatly increasing the practicality of the device, and a sliding groove 36 is provided on the side of the top of the workbench 14 away from the movable groove 31. The bottom ends of the two groups of clamping plates 35 are connected to the side away from the screw sleeves 34. Slide blocks 37 are connected to the two groups of slide blocks 37 in the sliding grooves 36, so that the movement of the clamping plate 35 is more stable and the clamping is also more secure.

[0024] As an implementation method in this embodiment, Figure 4 and Figure 5 As shown, the pressing assembly 4 includes an L-shaped plate 41, which is fixedly mounted on the top of the clamping plate 35, and an electric telescopic rod 42 is mounted on the bottom end of the L-shaped plate 41, and a mounting plate 43 is mounted on the bottom end of the electric telescopic rod 42. A plurality of adjustment assemblies 5 are equidistantly mounted on the surface of the mounting plate 43. This structure enables the adjustment assembly 5 to press down the workpiece, so that the workpiece can be fixed more firmly, greatly increasing the stability of the device. The adjustment assembly 5 includes a slide bar 51, and the slide bar 51 is slidably mounted in a through hole opened on the surface of the mounting plate 43. The bottom end of the slide bar 51 is connected with a pressing block 52, and a spring 53 is sleeved on one side of the slide bar 51 surface close to the pressing block 52. This structure allows adjustment according to the flatness of the workpiece surface, so that multiple positions of the workpiece with different flatness can be fixed. In addition, the operation is simple and there is no need for manual adjustment one by one, which greatly increases the convenience of the device. A rubber pad 54 is glued to the bottom end of the pressing block 52, so that the pressing block 52 can reduce the wear of the workpiece on the workpiece when pressing the workpiece, greatly reducing the possibility of the workpiece being worn.

[0025] Working principle: If the accessories of the inspection fixture need to be processed, it is only necessary to start the motor 1 23 to drive the gear 22 to rotate. Through the connecting rod 25, the two sets of gears 22 rotate at the same time. Through meshing, the gear 22 drives the rack 24 to slide in the installation groove 21, and the rack 24 can drive the workbench 14 to move until the workbench 14 is moved to one side of the connecting table 13, away from the engraving and milling mechanism 11. At this time, the workbench 14 will also drive the T-bar 16 to slide in the T-slot 15, and then the workpiece can be placed on the top of the workbench 14, between the two sets of clamping plates 35, and then start the motor 2 32 to drive the bidirectional screw 33 to rotate. Through the rotation of the thread, the bidirectional screw 33 drives the two sets of screw sleeves 34 to move closer to each other, and the screw sleeve 34 drives the screw sleeve 34 to move. At this time, the clamping plate 35 will also drive the slider 37 to slide in the slide groove 36 until the two sets of clamping plates 35 clamp the workpiece;

[0026] In addition, the clamping plate 35 will also drive the L-shaped plate 41, the electric telescopic rod 42, the mounting plate 43 and the adjusting assembly 5 to move at the same time. When the clamping plate 35 abuts against the workpiece, the electric telescopic rod 42 can be started to drive the mounting plate 43 to move downward, and the mounting plate 43 drives a plurality of groups of sliding rods 51 to move downward, and a plurality of groups of sliding rods 51 drive a plurality of groups of pressing blocks 52 to move downward until the plurality of groups of pressing blocks 52 are driven to press down and fix the workpiece. At this time, the plurality of groups of pressing blocks 52 can slide and adjust the height of the pressing blocks 52 according to the different positions and flatness of the pressed workpiece, and compress the springs 53 to different degrees, so that the restoring force of the springs 53 can be used to push the pressing blocks 52 to press the workpiece, so as to realize pressing down and fixing the positions of the workpiece with different flatness, so that the workpiece is fixed more firmly, which greatly increases the practicality of the device.

[0027] Finally, after the workpiece is fixed, the motor 23 can be started again to drive the two sets of gears 22 to rotate in the opposite direction. The gear 22 can drive the workbench 14 to move back through the rack 24 until the workbench 14 is reset, so that the workpiece is located directly under the engraving and milling mechanism 11. The engraving and milling mechanism 11 can then be started to engrave and mill the workpiece to complete the processing.

[0028] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
