Embodiment 1

[0020] The invention discloses an axial limiter suitable for a transmission box of a CNC floor boring and milling machine, comprising two semicircular limit blocks 4 sleeved on the outer circle of a nut 1 in the transmission box. The block 4 is provided with a protruding step 3, and the step 3 cooperates with the limit groove provided on the outer circle of the nut 1. The semicircular limit block 4 is covered with a locking sleeve 6, and the locking sleeve 6 is Ejection screw holes 5 are provided.

Embodiment 2

[0022] A preferred embodiment of the present invention: with reference to the description attached figure 1 and 2 , the present invention is composed of two semicircular limit blocks 4 that have a cooperative relationship with the outer circle of the nut 1 . The semicircular limit block 4 has a step 3, the width of the step 3 is determined according to the size of the limit groove of the nut 1 and the size of the axial force, and cooperates with it to ensure accurate axial limit; the semicircle A locking sleeve 6 with two ejected screw holes 5 is placed on the outer surface of the shape limiting block 4, and the locking sleeve 6 locks the semicircular limiting block 4 during work, and the locking sleeve is fixed with the retaining ring 7 6 position to ensure reliable operation of the shaft end limiter. During maintenance, two screws are screwed into two ejection screw holes 5 to withstand the end face of the nut sleeve 2 and the lock sleeve 6 can be ejected from the outer su...

Abstract

The invention discloses an axial limiter suitable for a transmission case of a numerical control floor type boring and milling machine. The axial limiter comprises two semicircular limit blocks sleeved on the outer circle of a nut in the transmission case. A protruded step is arranged on the semicircular limit blocks and is matched with a limit groove reserved on the outer circle of the nut; and a locking sleeve is sleeved out of the semicircular limit blocks and is provided with an ejecting screw hole. The axial limiter can bear a larger axial force and ensure axial pressing so as to ensure axial precision.

Description

technical field [0001] The invention relates to the technical field of structural improvement related to the transmission box of a CNC floor boring and milling machine, and specifically relates to an axial limiter. Background technique [0002] The nuts in the gearbox of the CNC floor boring and milling machine bear a large bidirectional axial load, and the requirements for axial positioning accuracy are also very high. The nut flange can only make the nut sleeve bear force in one direction, and due to structural limitations, the screw is pulled in the opposite direction to bear the axial load in the other direction. The screw is easily deformed under the action of large load and tensile stress for a long time, which affects the axial precision. [0003] The publication number is CN2058869, and the publication date is July 4, 1990. The Chinese patent document discloses a three-jaw self-centering chuck bevel gear limiter, which is used to install and limit the bevel gear wit...
