Embodiment 1

[0020] Such as figure 1 with figure 2 , an internal thread processing mechanism, including a workbench 1, on which a fixing plate 6 for hub fixing is arranged, the upper surface of the workbench 1 is a horizontal plane, and an axial drill 5 and a radial drill 2. Both the axial drill 5 and the radial drill 2 are fixed with a wire cutter, the axis of the wire cutter on the axial drill 5 is parallel to the horizontal plane, and the axis of the wire cutter on the radial drill 2 is inclined relative to the horizontal plane;

[0021] Both the axial drill 5 and the radial drill 2 are fixed on the workbench 1, the axial drill 5 brakes the rotation of the corresponding wire cutter and reciprocates along the axial direction of the wire cutter 78, and the radial drill 5 2 The braking corresponds to the rotation of the wire cutter and the reciprocating movement along the axial direction of the wire cutter 78.

[0022] Specifically, in the present invention, the set fixing plate 6 is us...

Embodiment 2

[0024] Such as figure 1 with figure 2 , this embodiment is further defined on the basis of Embodiment 1: as a structural form that can efficiently complete the tapping process, facilitate the reduction of the volume of the present invention, and avoid the mutual influence of the axial drills 5 on the same side of the fixed plate 6 , there are two axial drills 5 located on different sides of the fixing plate 6, and one radial drill 2.

[0025] As a radial drill 2 fixing structure that is beneficial to ensure that the thread cutter on the radial drill 2 is located in the radial direction of the hub, it also includes a column 3, the column 3 is perpendicular to the upper surface of the workbench 1, and the column 3 is provided with a position at The column 3 is axially adjustable with a shaft sleeve 4 , a connecting rod 8 is fixed on the shaft sleeve 4 , and the radial drill 2 is fixed on the connecting rod 8 .

[0026] In order to facilitate the adjustment of the coaxiality b...

Embodiment 3

[0028] Such as figure 1 with figure 2 , this embodiment further defines the present invention on the basis of any one of the above embodiments, as a structural form of a radial drill 2 and an axial drill 5 that facilitate the realization of a brake wire cutter, the radial drill 2 and the shaft The drills 5 are all composed of the following parts: installation cylinder 71, bearing bush 72, motor 73, contact slider 74, cylinder 75, wire cutter clip 77, the installation cylinder 71 is tubular, and the bearing bush 72 is fixed on the inner wall surface of the installation cylinder 71 Above, the cylinder 75 is fixed on any one end of the installation cylinder 71, the motor 73 is fixed on the piston rod of the cylinder 75, the thread cutter clip 77 is fixed on the rotor 76 of the motor 73, the piston rod of the cylinder 75, the installation cylinder 71, the rotor 76 three The axes of those are collinear, the contact slider 74 is fixed on the shell of the motor 73, the contact slid...

Abstract

The invention discloses an internal screw thread processing mechanism, which comprises a work table, wherein a fixing plate used for wheel hub fixation is arranged on the work table, the upper surface of the work table is a horizontal plane, the internal screw thread processing mechanism also comprises an axial drill and a radial drill, screwdrivers are respectively and fixedly arranged on the axial drill and the radial drill, the axial line of the screwdriver arranged on the axial drill is parallel to the horizontal plane, the axial line of the screwdriver arranged on the radial drill is inclined relative to the horizontal plane, the axial drill and the radial drill are respectively and fixedly arranged on the work table, the axial drill braking corresponds to the screwdriver rotation and the reciprocating movement along the axial direction of the screwdriver, and the radial drill braking corresponds to the screwdriver rotation and the reciprocating movement along the axial direction of the screwdriver. The internal screw thread processing mechanism has the advantages that the structure is simple, and the wheel hub thread tapping processing efficiency can be favorably improved.

Description

technical field [0001] The invention relates to the field of automobile hub manufacturing equipment, in particular to an internal thread processing mechanism. Background technique [0002] The wheel hub of automobile in the prior art can be divided into steel wheel hub and alloy wheel hub two big classes according to material. The main advantage of steel wheels is that the manufacturing process is simple, the cost is relatively low, and the ability to resist metal fatigue is very strong, which is what we commonly call cheap and strong. However, the disadvantages of steel wheels are also relatively prominent, that is, ugly appearance, heavy weight, large inertial resistance, poor heat dissipation, and very easy to rust. Relatively speaking, alloy wheels can just make up for such problems. The weight and inertial resistance are small, the manufacturing precision is high, the deformation at high speed rotation is small, and the inertial resistance is small, which is beneficial...
