Description

Technical Field

[0001] The invention relates to the technical field of brush handle drilling, in particular to a brush handle drilling device with a debris cleaning function. Background Art

[0002] Drilling equipment is widely used in various industries, covering fields such as electronic manufacturing, construction engineering, furniture manufacturing and decoration technology.

[0003] In recent years, with the increasing demand for use, various types of brushes have begun to appear on the market. However, conventional drilling equipment cannot meet the diverse drilling needs of brush handles. When drilling, ordinary drills mainly rely on the discharge grooves on the drill to guide the debris. The debris that has left the chip discharge groove will move in the circumferential direction under the action of centrifugal force, which will not only cause friction damage to the equipment, but also threaten the safety of the operator.

[0004] In addition, the debris is mostly scattered in disordered motion and easily adheres to the fixture, affecting the positioning accuracy during continuous processing. Summary of the invention

[0005] The object of the present invention is to provide a brush handle drilling device with a debris cleaning function to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions: A brush handle drilling device with a debris cleaning function, the drilling device is used to drill holes in the brush handle, the drilling device includes a frame, a power device, a flow guide device and a clamping device, the power device is connected to the frame, the clamping device is connected to the frame, the clamping device is used to clamp the brush handle, the flow guide device is tightly connected to the frame, and the flow guide device is used to clean debris from the part of the brush handle to be drilled.

[0007] The frame serves as the main installation base and is used to install and fix other devices. When drilling a hole in the brush handle, first fix the brush handle through a clamping device. After fixation, drill through a power device. During the drilling process, local air circulation is performed on the part of the brush handle to be drilled through a flow guide device, which not only cools the drilling area, but also automatically collects the generated debris through local air circulation to prevent impurities from accumulating and affecting the drilling accuracy.

[0008] Furthermore, the clamping device includes a turntable, the turntable is rotatably connected to the frame, a plurality of clamps are provided on the turntable along the circumference, the clamps are used to clamp the brush handle, the power device includes a power motor, a transmission rod and a drill bit, the power motor is tightly connected to the frame, the transmission rod is rotatably connected to the frame, and a drill bit is provided at the lower end of the transmission rod; The flow guide device includes a ring seat and a high-pressure air pipe. The ring seat and the frame are tightly connected. A working chamber is arranged on the ring seat. A plurality of air outlets are arranged around the working chamber. The high-pressure air pipe is connected with the air outlet inlet, and the air outlet faces the contact part between the drill bit and the brush handle.

[0009] Several sets of clamps are set on the upper surface of the turntable. The clamps adopt a movable structure and are used to clamp brush handles of different specifications to prevent the brush handles from shaking during drilling, which affects the drilling quality. The power motor is fixed on the frame to output torque to drive the transmission rod to rotate. The transmission rod is used to drive the drill bit below to rotate, so as to drill the brush handle. During the drilling process, high-pressure airflow is sprayed through the high-pressure air pipe. This high-pressure airflow can be used to cool the drill bit. At the same time, it can blow away the debris from the drilling to prevent the debris from local deposition and affect the continuous drilling efficiency.

[0010] Furthermore, the flow guide device also includes a negative pressure pipe, a plurality of return channels are provided on the ring seat, the return channels are connected to the working chamber, the return channels are connected to the negative pressure pipe pipeline, and the lower surface of the ring seat and the upper surface of the fixture are at the same height; The outlet of the air outlet is arranged obliquely, and the air outlet faces the tangent direction of the chip flute of the drill.

[0011] Since the drill bit is generally spiral-shaped, the spiral groove on it is a chip discharge groove, which is used to discharge the debris generated by drilling. The outlet of the air outlet is arranged obliquely and tangentially toward the drill bit to impact the debris under the centrifugal action. Through two opposing forces, the airflow generated by the upper air outlet is tilted downward to impact the debris, forming an air film layer to reduce the speed of the debris and prevent the debris from escaping from the working chamber. At the same time, a negative pressure is created in the return channel through the negative pressure pipe, so that a pressure difference is formed at the inlet and outlet of the return channel. The debris that is stalled upward by the airflow impact flows under the action of the pressure difference and tilts downward to the return channel, thereby automatically collecting the drilling debris to prevent the debris from depositing and affecting the positioning accuracy of the subsequent fixture.

[0012] Furthermore, a screening flow channel is provided on the ring seat, the screening flow channel is arranged in a spiral, and the spiral diameter of the screening flow channel is gradually reduced along the flow direction of the internal medium.

[0013] By setting up a screening flow channel, when the impure airflow enters the return channel and finally enters the screening flow channel, the spiral diameter is gradually changed. When the impure airflow flows forward along the screening flow channel, as the spiral diameter gradually decreases, the centrifugal force on the debris in the impure airflow increases, and under the action of the centrifugal force, the debris flows along the outer wall of the screening flow channel, thereby performing automatic screening.

[0014] Furthermore, the flow guide device also includes a waste pipe, the negative pressure pipe is connected to the return channel through the screening channel, the negative pressure pipe is connected to the inner layer of the screening channel, and the waste pipe is connected to the outer layer of the screening channel.

[0015] By setting up a waste pipe, when the negative pressure pipe creates negative pressure, it induces the impurity-containing air flow to enter the screening channel and completes the screening, and then flows to the end of the screening channel. Due to the mass difference, the debris is located in the outer layer of the screening channel and the gas is located in the inner layer of the screening channel, and they flow in layers. Under the action of inertia, the debris enters the waste pipe, and the gas is led out through the negative pressure pipe, thereby automatically screening and collecting the debris.

[0016] Furthermore, two turntables are provided, a manipulator is provided between the two turntables, and the position of the clamp located directly below the part of the brush handle to be drilled is hollowed out.

[0017] Two turntables are set up to facilitate double-station drilling. A manipulator is set up to transfer the brush handle between the two stations. The bottom of the fixture is hollowed out to prevent material interference with the drilling. When the brush handle needs to drill two holes, the negative pressure suction of the negative pressure tube is increased when drilling the second hole, so that the airflow passing through the first drill hole below will also carry the debris into the return channel, improving the quality of debris cleaning.

[0018] As an optimization, the clamping device also includes a rotary motor, the rotary motor is tightly connected to the frame, and the output end of the rotary motor is transmission-connected to the turntable. The rotary motor is fixed to the frame, and drives the turntable to rotate through the output torque, thereby transferring the brush handle to the bottom of the drill bit.

[0019] As an optimization, the power device also includes a downward pressure cylinder, a guide rod and a mounting seat. The downward pressure cylinder is tightly connected to the frame. Two guide rods are set at the output end of the downward pressure cylinder. The output end of the downward pressure cylinder is connected to the mounting seat through the two guide rods, and the mounting seat is connected to the transmission rod. By setting a downward pressure cylinder, fixed on the frame, the output displacement drives the guide rod to move downward, thereby linking the mounting seat, driving the transmission rod downward, and assisting in drilling. By setting two guide rods, sliding guidance is performed to improve the smoothness of sliding.

[0020] Furthermore, the transmission rod includes a base rod, a movable rod and a swivel seat. The base rod is rotatably connected to the frame, a pulley is mounted on the base rod, the power motor and the pulley are driven by a belt, a key slot is set on the movable rod, the lower end of the base rod is inserted into the key slot, the base rod and the movable rod are slidably connected, a swivel seat is mounted on the outer ring of the lower end of the movable rod, a swivel groove is provided on the mounting seat, the swivel seat is inserted into the swivel groove, and the mounting seat is transmission-connected to the swivel seat through the swivel groove.

[0021] The base rod is supported on the frame through bearings, a keyway is arranged on the movable rod, and the lower end of the base rod is inserted into the keyway. The power motor drives the pulley to rotate through the belt transmission, thereby driving the base rod to rotate. The keyway transmission enables the base rod to drive the movable rod to rotate, and at the same time, the lower end of the base rod can slide in the keyway in the vertical direction. That is, when drilling, the drill bit is driven to rotate through the movable rod, and the mounting seat guides the swivel seat for rotation without limiting the rotation of the swivel seat. At the same time, the swivel seat can be driven to move downward, and the transmission is sequentially transmitted through the downward pressure cylinder, the guide rod, the mounting seat and the swivel seat, so as to drive the drill bit to keep downward during the rotation to perform the drilling operation.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: the outlet of the air outlet is arranged obliquely and flows tangentially toward the drill bit to impact the debris under the centrifugal action. Through two opposing forces, the airflow generated by the upper air outlet is tilted downward to impact the debris, forming an air film layer, slowing down the debris and preventing the debris from escaping from the working chamber. At the same time, negative pressure is created in the return channel through the negative pressure pipe, so that a pressure difference is formed at the inlet and outlet of the return channel. The debris that is stalled upward by the airflow impact flows under the action of the pressure difference and flows obliquely downward toward the return channel, thereby self-extraction of the drilling debris. Automatic collection prevents debris from depositing and affecting the positioning accuracy of subsequent fixtures; through the gradual change of the spiral diameter, when the impurity-containing airflow flows forward along the screening channel, as the spiral diameter gradually decreases, the centrifugal force on the debris in the impurity-containing airflow increases, and under the action of centrifugal force, the debris flows along the outer wall of the screening channel, thereby automatically screening; due to the difference in mass, the debris is located in the outer layer of the screening channel, and the gas is located in the inner layer of the screening channel, and stratified flow is carried out. Under the action of inertia, the debris enters the waste pipe, and the gas is led out through the negative pressure pipe, thereby automatically screening and collecting the debris.

The power motor 21 is fixed on the frame 1 to output torque to drive the transmission rod 22 to rotate. The transmission rod 22 is used to drive the drill bit 26 below to rotate, thereby drilling the brush handle. During the drilling process, a high-pressure airflow is sprayed through the high-pressure air pipe 32. This high-pressure airflow can be used to cool the drill bit 26. At the same time, it can blow away the debris from the drilling to prevent the debris from local deposition and affecting the continuous drilling efficiency.

[0032] Since the drill bit 26 is generally spiral-shaped, the spiral groove on it is a chip removal groove for discharging the debris generated by drilling. The outlet of the air outlet 311 is arranged obliquely and tangentially toward the drill bit 26 to impact the debris under the centrifugal action. Through two opposite forces, the airflow generated by the upper air outlet 311 is tilted downward to impact the debris, forming an air film layer, slowing down the debris and preventing the debris from escaping from the working chamber 312.

[0034] By setting up the screening channel 314, when the impure airflow enters the return channel 313 and finally enters the screening channel 314, the spiral diameter is gradually changed. When the impure airflow flows forward along the screening channel 314, as the spiral diameter gradually decreases, the centrifugal force on the debris in the impure airflow increases, and under the action of the centrifugal force, the debris flows along the outer wall of the screening channel 314, thereby performing automatic screening.

Under the action of inertia, the debris enters the waste pipe 34, and the gas is led out through the negative pressure pipe 33, so that the debris is automatically screened and collected.

[0037] Furthermore, two turntables 41 are provided, a manipulator is provided between the two turntables 41, and the position of the clamp 43 located directly below the part of the brush handle to be drilled is hollowed out.

[0038] Two turntables 41 are provided to facilitate double-station drilling. A manipulator is provided to transfer the brush handle between the two stations. The bottom of the clamp 43 is hollowed out to prevent material interference with the drilling. When the brush handle needs to drill two holes, the negative pressure suction of the negative pressure tube 33 is increased when drilling the second hole, so that the airflow passing through the first drilled hole below will also carry the debris into the return channel 313, thereby improving the debris cleaning quality.

Through two opposing forces, the airflow generated by the upper air outlet 311 is tilted downward to impact the debris, forming an air film layer to reduce the speed of the debris and prevent the debris from escaping from the working chamber 312. At the same time, a negative pressure is created in the return channel 313 through the negative pressure pipe 33, so that a pressure difference is formed between the inlet and outlet of the return channel 313. The debris that is stalled upward by the airflow impact flows under the action of the pressure difference and tilts downward to the return channel 313, thereby automatically collecting the drilling debris. , to prevent debris from depositing and affecting the positioning accuracy of the subsequent fixture 43; through the gradual change of the spiral diameter, when the impurity-containing airflow flows forward along the screening channel 314, as the spiral diameter gradually decreases, the centrifugal force on the debris in the impurity-containing airflow increases, and under the action of centrifugal force, the debris flows along the outer wall of the screening channel 314, thereby automatically screening; due to the mass difference, the debris is located in the outer layer of the screening channel 314, and the gas is located in the inner layer of the screening channel 314, and a layered flow is performed. Under the action of inertia, the debris enters the waste pipe 34, and the gas is led out through the negative pressure pipe 33, thereby automatically screening and collecting the debris.
