Description

Technical Field

[0001] The utility model relates to the technical field of drilling and tapping machines, in particular to a positioning device for drilling and tapping machines. Background Art

[0002] Drilling and tapping machines are common equipment in metal processing. Their main purpose is to perform operations such as drilling and tapping. During the processing, high precision and high processing efficiency are required, so they are widely used in the processing and manufacturing of various parts.

[0003] In the prior art, when a drilling machine is drilling a hole in an object, the object itself does not have a positioning function, which causes the object to slide during the drilling process, affecting the drilling quality. Therefore, it is necessary to position the object through a clamping plate to prevent the object from sliding during the drilling process. However, the existing positioning mechanism can only position objects with regular shapes. When processing cylindrical workpieces, the positioning effect of the positioning mechanism is not high, resulting in the cylindrical workpiece still sliding during the drilling process, reducing its yield rate. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a drilling and tapping machine positioning device.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a drilling and tapping machine positioning device, comprising a body, an X-axis slide seat is slidably connected to the top of the body, a Z-axis slide seat is slidably connected to the surface of the X-axis slide seat, a Y-axis slide seat is slidably connected to the bottom of the Y-axis slide seat, a drill bit is rotatably connected to the bottom of the Y-axis slide seat, and the drill bit is driven by an external motor, a coolant tank is provided inside the Y-axis slide seat, and a cooling nozzle is connected to the inside of the coolant tank, a workbench is fixed on the top of the body, a cross groove is provided on the surface of the workbench, sliders are slidably connected to the inside of the cross groove, and the sliders are distributed in a circular array, shock absorbing springs are elastically connected between the two sides of the slider and the side walls of the cross groove, a connecting rod is rotatably connected to the bottom of the slider, a lifting seat is rotatably connected to the bottom of the connecting rod, a screw rod is threadedly connected to the inside of the lifting seat, and both ends of the screw rod are connected to the inner wall bearing of the workbench, a spur bevel gear is fixed to the bottom end of the screw rod, a side bevel gear is meshed with the surface of the spur bevel gear, and the side bevel gear is driven by a gear rotation motor, and a positioning plate is provided on the top of the slider.

[0006] Preferably, the positioning plate is detachably connected to the slider. According to the number of positioning plates that can be freely rotated for processing workpieces, the applicable scope of the positioning mechanism is improved.

[0007] Preferably, a reflux box is provided on both sides of the workbench, the reflux box is connected to a reflux pipe, the other end of the reflux pipe is connected to a water pump, and the water pump is arranged inside the Y-axis slide. When the existing drilling and tapping machine is processing, it is necessary to continuously spray coolant on the workpiece to cool it down, but a large amount of coolant cannot be recycled, resulting in waste. To address this problem, the utility model adopts a circulation mechanism, the coolant is recovered into the reflux box, and the coolant is pumped from the reflux pipe into the coolant tank through a water pump for recycling, thereby reducing costs.

[0008] Preferably, a filter is fixed on the top of the reflux box. A large amount of waste chips will be generated when drilling holes, which is easy to block the water inlet of the reflux pipe. In this regard, the utility model fixes a filter on the top of the reflux box to filter the waste chips and prevent them from blocking the water inlet of the reflux pipe.

[0009] Preferably, a rubber sleeve is bonded to the surface of the positioning plate, and the rubber sleeve plays a protective role to prevent the positioning plate from scratching the surface of the workpiece when clamping the workpiece.

[0010] Preferably, the top surface of the reflux box is configured as an inclined surface to facilitate the coolant to enter the reflux pipe.

[0011] Preferably, the return pipe is a hose to prevent the Y-axis slide from breaking at the return pipe interface when the Y-axis slide moves.

[0012] Beneficial Effects

[0013] In the prior art, when a drilling machine is drilling a hole in an object, since the object itself does not have a positioning function, the object is prone to sliding during the drilling process, which affects the drilling quality. Therefore, it is necessary to position the object through a clamping plate to prevent the object from sliding during the drilling process. However, the existing positioning mechanism can only position objects with regular shapes. When processing a cylindrical workpiece, the positioning effect of the positioning mechanism is not high, which causes the cylindrical workpiece to still slide during the drilling process, thereby reducing its yield rate. To address this problem, the utility model adopts a four-corner positioning mechanism, places the cylindrical workpiece on the top of the workbench, turns on the gear rotation motor to drive the side bevel gear to rotate, and the side bevel gear drives the spur bevel gear to rotate, thereby driving the screw to rotate, driving the lifting seat to move downward, thereby driving the slider to gather inward, fixing the cylindrical workpiece on all sides, preventing the object from sliding during the drilling process, and improving the yield rate of the workpiece.
