Abstract

The utility model relates to a two-sided hole-punching machine for a valve. A supporting bracket is fixedly arranged in the middle of the upper end of a rack; a cylinder downward vertically is arranged on the supporting bracket; the supporting bracket below the cylinder is internally fixedly provided with a tooling seat; horizontally-arranged parallel guide rails are fixedly arranged on the rack at two horizontal sides of the tooling seat; cutter seats are arranged in a guide and sliding mode on the parallel guide rails at two sides; a transmission gear box is vertically and fixedly arranged on the cutter seat; a driving motor is fixedly arranged on the cutter seat outside the transmission gear box; four coaxial drill bits are uniformly and horizontally arranged on one side wall, facing the tooling seat, of the transmission gear box; and the four drill bits are driven by the driving motor for synchronous rotation. The two-sided hole-punching machine for a valve has the advantages that the structure is simple, the design is reasonable, the processing effects are good, drilling positions are standard and unified, time can be effectively saved, the labor intensity of workers is lessened, and the working efficiency is improved.

Description

The two-sided puncher of valve

Technical field

The utility model belongs to valve field, the two-sided puncher of especially a kind of valve.

Background technology

Use at engineering pipeline transportation art valve is very extensive, valve need to connect by flange, at present, flange mounting hole need to punch and make successively, the positional precision of installing hole, repeatedly installs workpiece and easily causes position skew, is difficult to guarantee the precision of bore position, and labor strength is large, wastes time and energy.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of reasonable in design, simple in structure, easy to operate, safe and reliable valve two-sided puncher.

The utility model solves its technical problem and takes following technical scheme to realize:

The two-sided puncher of a kind of valve, it is characterized in that: comprise frame, bracing frame, cylinder, workseat, closed slide, the base of tool, uni-drive gear box, drive motors, drill bit, guiding leading screw and guide motor, frame upper center is fixed with a bracing frame, one cylinder is straight down installed on this bracing frame, in the bracing frame of this cylinder below, be fixed with a workseat, in the frame of this workseat both lateral sides, be all fixed with the closed slide that horizontal cross arranges, on the closed slide of these both sides, all guiding is slidably fitted with a base of tool, on this base of tool, be vertically fixed with a uni-drive gear box, on the base of tool in uni-drive gear box outside, be fixed with a drive motors, uni-drive gear box is horizontal uniform four the homoaxial drill bits that are provided with on a sidewall of workseat, these four drill bits drive synchronous rotary by drive motors.

And, on described toolframe, radial equipartition is provided with four drill bits, the end of these four drill bits is all installed with a driven gear in toolframe, and these four driven gears all mesh with a center main moving gear, and this center main moving gear is arranged on the output shaft of drive motors.

And described frame two middle side parts are all symmetrically installed with a guiding leading screw, the nut that this guiding leading screw engagement base of tool lower end is fixedly mounted with also drives base of tool horizontal cross to move back and forth, and leading screw outer end all connects a guide motor by the belt transmission of a correspondence.

Advantage of the present utility model and good effect are:

The utility model is simple in structure, reasonable in design, simple operation, and processing effect is good, and bore position standard is unified, and effectively saves time, and alleviates labor strength, promotes operating efficiency.

Accompanying drawing explanation

Fig. 1 is structural front view of the present utility model;

Fig. 2 be in Fig. 1 A-A to cross-sectional view.

The specific embodiment

Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.

The two-sided puncher of a kind of valve, comprise frame 12, bracing frame 7, cylinder 6, workseat 11, closed slide 8, the base of tool 2, uni-drive gear box 4, drive motors 1, drill bit 5, guiding leading screw 14 and guide motor 10, frame upper center is fixed with a bracing frame, one cylinder is straight down installed on this bracing frame, in the bracing frame of this cylinder below, be fixed with a workseat, in the frame of this workseat both lateral sides, be all fixed with the closed slide that horizontal cross arranges, on the closed slide of these both sides, all guiding is slidably fitted with a base of tool, on this base of tool, be vertically fixed with a uni-drive gear box, on the base of tool in uni-drive gear box outside, be fixed with a drive motors, uni-drive gear box is horizontal uniform four the homoaxial drill bits that are provided with on a sidewall of workseat, these four drill bits drive synchronous rotary by drive motors.

Gear box structure as shown in Figure 2, on toolframe, radial equipartition is provided with four drill bits, the end of these four drill bits is all installed with a driven gear 16 in toolframe, these four driven gears all mesh with a center main moving gear 15, and this center main moving gear is arranged on the output shaft 3 of drive motors.

In order to control drill bit horizontal cross, move, described frame two middle side parts are all symmetrically installed with a guiding leading screw, the nut 13 that this guiding leading screw engagement base of tool lower end is fixedly mounted with also drives base of tool horizontal cross to move back and forth, and leading screw outer end is the guide motor that is in transmission connection of the belt 9 by a correspondence all.

Add man-hour, the workpiece of giving to be processed is installed on workseat, and start cylinder-pressing fixation workpiece, the guide motor of both sides drives respectively the base of tool of this side to move to middle part, the drive motors of both sides drives respectively four bits simultaneously, can synchronous processing, also can drive respectively processing.

Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: within not departing from the spirit and scope of the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
