Problems solved by technology

[0002] There is a circular transmission shaft, the two ends of which are provided with symmetrical through-holes that run through the shaft body in the radial direction. The traditional processing method is to use a bench drill to drill one end and then drill the other end. The disadvantage of this processing method is that : First, two processes are required, and second, when processing the other end, in order to make the two holes symmetrical, accurate positioning is required, which greatly increases the difficulty of the process
In addition, there is no automatic feeding and discharging mechanism in the traditional processing method, resulting in slow processing efficiency

Embodiment 1）

[0023] Figure 1 to Figure 3 One specific embodiment of the invention is shown.

[0024] Present embodiment is a kind of double drill mechanism, see Figure 1 to Figure 3 As shown, the double drill mechanism 3 includes a mounting plate 4, a main shaft 31 that is rotatably arranged at the center of the mounting plate, a drive wheel 32 fixed on the main shaft, a first transmission shaft 33 that is rotatably disposed on the mounting plate, and is fixedly arranged on the second The first driven wheel 34 on the upper end of a transmission shaft, the first drill bit 35 arranged on the lower end of the first transmission shaft, the second transmission shaft 36 that is rotated on the mounting plate, and the second driven wheel fixed on the upper end of the second transmission shaft 37 and the second drill bit 38 that is arranged on the second drive shaft lower end; The first drill bit and the second drill bit rotate.

[0025] The main shaft, the first transmission shaft and the sec...

specific Embodiment approach

[0086] This application example is basically the same as application example 1, the difference is: see Figure 13 to Figure 16 As shown, the shape of the trough in this application example is U-shaped; the material delivery wheel in this application example is provided with a first slider 51 and a first guide rail 52 adapted to the first slide rail, which is used to drive the second A material clamping cylinder 53 for reciprocating sliding of a slider, a second slider 54, a second guide rail 55 adapted to the second slider, and a discharge cylinder 56 for driving the second slider to reciprocate and slide.

[0087] When the trough is located directly below the through hole on the blocking member, the first guide rail 52 is set along the horizontal direction, and the material clamping cylinder can drive the first slider to move back and forth along the horizontal direction, and clamp or loosen the workpiece during the moving process ; The second guide rail is set along the vert...

Abstract

The invention discloses a double-drill mechanism for a bench drill. The double-drill mechanism comprises a mounting plate, a main shaft, a driving wheel, a first transmission shaft, a first driven wheel, a first drill, a second transmission shaft, a second driven wheel and a second drill, wherein the main shaft synchronously drives the first drill and the second drill to rotate; a first bearing for the main shaft, an upper bearing for the main shaft and a lower bearing for the main shaft are sequentially arranged on the main shaft from top to bottom; an upper bearing for the first transmission shaft and a lower bearing for the first transmission shaft are sequentially arranged on the first transmission shaft from top to bottom, and a first driving wheel is arranged below the lower bearing for the first transmission shaft; an upper bearing for the second transmission shaft and a lower bearing for the second transmission shaft are sequentially arranged on the second transmission shaft from top to bottom, and a second driving wheel is arranged above the upper bearing for the second transmission shaft; the driving wheel, the first driven wheel and the second driven wheel are arranged in the mounting plate. The double-drill mechanism can simultaneously perform drilling operation at the two ends of a shaft body.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a double-drill mechanism for bench drills. Background technique [0002] There is a circular transmission shaft, the two ends of which are provided with symmetrical through holes radially penetrating through the shaft body. The traditional processing method is to use a bench drill to drill one end and then drill the other end. The disadvantage of this processing method is that : The first requires two procedures, and the second is to make the two holes symmetrical in order to make the two holes symmetrical, and accurate positioning is required, which greatly increases the difficulty of the process. In addition, there is no automatic feeding and discharging mechanism in the traditional processing method, resulting in slow processing efficiency. Contents of the invention [0003] The object of the present invention is to provide a double-drilling mech...
