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 9 One specific embodiment of the invention is shown.

[0024] This embodiment is a kind of automatic feeding double drill bench drill, see Figure 1 to Figure 9 As shown, the bench drill includes a bench drill body 1 and a feeding mechanism 2 .

[0025] The bench drill body 1 includes a double drill mechanism 3 and a lifting mechanism (not shown in the figure) for driving the double drill mechanism 3 to move up and down.

[0026] See Figure 1 to Figure 4 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 driving wheel 32 that is fixed on the main shaft, a first transmission shaft 33 that is rotatably disposed on the mounting plate, and is fixedly arranged on the first The first driven wheel 34 at the upper end of the transmission shaft, the first drill bit 35 arranged at the lower end of the first transmission shaft, the second transmission shaft 36...

Embodiment 2）

[0060] Figure 10 to Figure 12 A second specific application embodiment of the invention is shown.

[0061] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 10 to Figure 12 As shown, this embodiment no longer sets the cylinder and the pin shaft, but directly uses a geared motor (not shown in the figure) to drive the reciprocating rotation of the feed wheel; specifically, the geared motor can be used to directly drive the shaft of the feed wheel to rotate In addition, a plurality of travel switches can be provided on the frame body, and a plurality of triggers for triggering a corresponding travel switch can be set on the material transfer wheel, so that the position of the transfer wheel can be judged by the trigger status of each travel switch. Position, to automatically control the operation of the geared motor, that is, to realize the automatic operation of the control material transfer wheel; through this structure, ordinary motors can...

specific Embodiment approach

[0064] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 13 to Figure 16 As shown, the shape of the trough in this embodiment is U-shaped; the material transfer wheel in this embodiment is provided with a first slide block 51 and a first guide rail 52 adapted to the first slide rail for driving the first slide rail. 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.

[0065] 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 vertical direction, and the discharg...

Abstract

The invention discloses a double-drill-bit bench drill with an automatic feeding mechanism. The double-drill-bit bench drill comprises a bench drill body and the automatic feeding mechanism; the bench drill body comprises a double-drill-bit mechanism and a lifting mechanism; the double-drill-bit mechanism comprises an installation disc, a main shaft rotationally arranged in the center of the installation disc, a driving wheel fixed to the main shaft, a first transmission shaft rotationally arranged on the installation disc, a first driven wheel fixedly arranged at the upper end of the first transmission shaft, a first drill bit arranged at the lower end of the first transmission shaft, a second transmission shaft rotationally arranged on the installation disc, a second driven wheel fixedly arranged at the upper end of the second transmission shaft and a second drill bit arranged at the lower end of the second transmission shaft; the main shaft, the first transmission shaft and the second transmission shaft are arranged in the plumb line direction; and the main shaft synchronously drives the first driven wheel and the second driven wheel to rotate through the driving wheel and further synchronously drives the first drill bit and the second drill bit to rotate. By means of the double-drill-bit bench drill, hole drilling operation can be carried out at the two ends of a shaft body at the same time, the machining efficiency is effectively improved, and the process difficulty is effectively reduced. The distance between the two drill bits can be adjusted in the manner that a third plate or a fifth plate is replaced.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a double-head bench drill with an automatic feeding mechanism. 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 ...
