Embodiment Construction
[0016] Loosen all the screws on the brake disc 21, use the inner hexagonal wrench to rotate the outer hexagonal shaft end of the worm 5, and drive the movable tool holder 2 to rotate through the worm wheel 23, and check the angle value indicated by the dial 24 at the same time. According to the taper value of the workpiece taper hole, adjust the deflection angle of the movable tool holder 2 to the required position, and use the constant torque wrench to tighten the screws at the brake disc 21 symmetrically to lock the movable tool holder 2 position. The position adjustment method of the boring head 20 is shown in the appendix Figure 5 , when the opening of the processed taper hole faces to the right, first adjust the orientation of the boring head 20 to ensure that the boring edge faces upwards; Figure 5 The position of the middle O point is determined by the initial position of the horizontal rotary plate sliding plate 6 of the ordinary boring machine and the adjustment ang...

The invention discloses an assisting device for boring and processing a tapered hole, and belongs to the technical field of machining. The device comprises a fixed tool seat, a movable tool seat, a guide key, a first pressing cover, a worm, a slide plate, a tapered roller bearing, a thrust roller bearing, a deep groove ball bearing, a Mohs hardness handle, a movable tool handle shaft, a slide block, a second pressing cover, a boring tool rod, a boring tool head, a tight braking plate, a first supporting shaft, a dial, a worm gear, a positioning plate, a second supporting shaft and an angular contact ball bearing. According to the device, the a deflection angle of the movable tool seat is adjusted through the worm gear and the worm; the worm is rotated according to the scale number as displayed by the dial; therefore, the movable tool seat can be adjusted to reach the angle position as requirement; then a screw on the tight braking plate can be pinched, so as to lock the movable tool seat through the tight braking plate; the torque for cutting of the boring rod is transmitted through the guide key; the feeding force is transmitted through a slide block assembly at the tail part of a tool rod. The device is assembled into the common boring machine, can achieve high-precision boring processing of the tapered hole, and is wide in size range of the processed tapered hole, and high in adaptability.
Description
[0001] Technical field: [0002] The invention belongs to the technical field of machining, and in particular relates to an auxiliary device for taper hole boring processing, which can bore and process high-precision taper holes whose diameter and taper are within a certain range. [0003] Background technique: [0004] The surface of box parts often needs to be processed with various taper holes. If a lathe is used to process taper holes, it is difficult to locate and align the holes, and the positional accuracy between hole systems is not easy to guarantee. It is a more suitable processing method to use ordinary boring machine to machine taper hole. At present, the boring and processing of taper holes on ordinary boring machines is generally performed by installing a set of professional tooling for boring taper holes. Although there are many types of tooling for boring taper holes, they can basically only realize the boring process of fixed taper holes, and the diameter rang...
