[0009] Preferably, an air nozzle is fixedly mounted on the fixing platform, and the air nozzle is arranged toward the upper surface of the bearing block.

[0010] By adopting the above technical solution, each time the vertical bearing seat is removed, the air nozzle blows air to the upper surface of the bearing block, so that the waste chips left on the bearing block can be blown away, so as to place the vertical bearing seat next time.

[0011] Preferably, in order to improve the clamping effect, the number of the lever cylinders is set to two, the two lever cylinders are symmetrically arranged on both sides of the bearing block, and the lever pressure arms of the lever cylinders can be pressed on the vertical bearing seat.

[0012] A hand-cranked wheel is fixed on the top of the screw rod.

[0018] The following is combined with Figure 2 This application is described in further detail.

[0019] The present application embodiment discloses a fixture for boring a vertical bearing seat, referring to Figure 2, including a fixed platform 1, a clamping mechanism is arranged on the side of the fixed platform 1, the clamping mechanism includes a bearing block 2, a top pressure block 3, a screw rod 4, a threaded seat 5, a guide rail 6 and a lever cylinder 7, the bearing block 2, the threaded seat 5, the guide rail 6 and the lever cylinder 7 are all fixedly connected to the side of the fixed platform 1, the lever cylinder 7 is arranged on the side of the bearing block 2, and is used to press the vertical bearing seat. In order to improve the pressing effect, the number of the lever cylinders 7 is set to two, and the two lever cylinders 7 are symmetrically arranged on both sides of the bearing block 2, and the lever pressure arms of the lever cylinders 7 can be pressed on the vertical bearing seat, the threaded seat 5 is arranged on the top of the bearing block 2, the screw rod 4 is threadedly connected in the threaded seat 5, the top pressure block 3 is rotatably connected to the bottom end of the screw rod 4, in order to facilitate the rotation of the screw rod 4, a hand-cranked wheel 8 is fixed on the top of the screw rod 4, guide rails 6 are symmetrically arranged on both sides of the top pressure block 3, the top pressure block 3 can slide up and down between the guide rails 6 on both sides, and a V-shaped positioning groove 31 with an opening facing downward is opened in the middle of the top pressure block 3;

[0020] In order to leave space for the boring tool, a clearance hole 11 is opened on the surface of the fixing platform 1.

[0021] In order to facilitate the placement of the vertical bearing seat, the side of the bearing block 2 away from the fixing platform 1 has an upwardly tilted flange 21, and the surface of the bearing block 2 is a smooth surface.

[0022] Reference Figure 2 An air nozzle 9 is also fixedly mounted on the fixing platform 1 , and the air nozzle 9 is arranged toward the upper surface of the bearing block 2 .
