Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of guide rail drilling, in particular to a full-automatic multi-axis linkage linear guide rail drilling equipment. BACKGROUND

[0002] Linear guide rail is a component used to support and guide movement, which is mainly used in high-precision or high-speed linear reciprocating motion occasions. In the production process of linear guide rail, it needs to be drilled. For long-stroke linear guide rails, multiple uniformly spaced holes need to be arranged along the movement direction of the guide rail. However, the existing linear guide rail drilling equipment has some defects and cannot meet the use requirements.

[0003] Conventional linear guide rail drilling equipment usually needs manual assistance and has low automation, which greatly restricts the drilling efficiency of linear guide rails. Some equipment chooses automatic processing mode. Automatic drilling can exert greater pressure to improve drilling speed, but correspondingly, the temperature of the drill bit will also rise significantly in a short time. Conventional heat dissipation methods lack effective means to deal with the large amount of heat output in a short time. On the other hand, the automatic equipment cannot handle the rapid temperature rise caused by abnormal conditions during the drilling process.

[0004] After drilling the linear guide rail, burrs and debris will be left inside the hole. The conventional debris recycling device can only collect the debris that has fallen off. The debris still attached to the surface of the hole and the burrs with very small force area do not have a positive collection effect. These debris are easy to fall off during the transportation process and then remain in the external working environment, affecting the cleanliness of the external environment.

Since the linear guide rail takes a short time to drill a single hole and a large number of holes, a certain time of transfer process will occur during the drilling process.

When abnormal temperature accumulation occurs during the drilling process, the heat dissipation capacity cannot meet the demand, at this time, the temperature is out of limit, in the case that the temperature is out of limit, the detection gas in the detection channel expands out of limit, which pushes the detection plate to move through the position sensor, the position sensor outputs a signal, the advancing module is controlled to retreat, after the temperature drops, the detection spring pushes the detection plate to pass through the position sensor again, the position sensor outputs a signal again, the advancing module is extended again after a set delay, and the drilling head continues to work.

[0010] Further, the fixed frame is internally provided with an upper cavity, a lower cavity and an extension slot, the upper end of the fixed frame is provided with a protruding block, the upper cavity is arranged above the lower cavity, one end of the extension slot is communicated with the upper cavity, the other end of the extension slot is communicated with the upper surface of the fixed frame, the protruding block is arranged at the center of the upper side of the fixed frame, the protruding block is tightly connected with the fixed frame, the collecting assembly comprises a lifting strip, a lifting cylinder, a spiral pipe, a separation sleeve, an extension rod, a threaded column, an automatic door and a covering sleeve, the lifting strip is slidingly connected with the extension slot, the upper end of the lifting strip is provided with a collecting port, the collecting port faces one side of the protruding block, the lifting cylinder is tightly connected with the bottom of the upper cavity, the output shaft of the lifting cylinder is tightly connected with the lifting strip, the spiral pipe is tightly connected with the upper cavity, the collecting port is connected with the spiral pipe through a pipeline, one end of the spiral pipe away from the collecting port is connected with the separation sleeve, the separation sleeve is arranged in the covering sleeve, the covering sleeve is tightly connected with the upper cavity, the bottom of the covering sleeve is communicated with the lower cavity, a screening net is arranged on the upper side of the separation sleeve, the automatic door is arranged at the bottom of the separation sleeve, the automatic door can seal the separation sleeve, a temporary storage slot is arranged in the protruding block, the extension rod is tightly connected with the side wall end face of the temporary storage slot, one side of the extension rod away from the side wall end face of the temporary storage slot is tightly connected with the threaded column, the extension rod is internally provided with an extension mechanism, the top of the separation sleeve is communicated with the extension slot through a pipeline, grinding particles are arranged on the inner wall of the spiral pipe, and an annular thread groove is arranged on the surface of the threaded column.

After the guide rail is punched, the lifting cylinder pushes the lifting strip to extend, the extension rod pushes the threaded column to extend into the punched hole on the guide rail, the extension mechanism in the extension rod is a conventional technical means in the field, and the specific structure is not described. The micro air flow pump starts to operate, and the air flow direction is set to draw air flow from the collecting port and output gas from the temporary storage slot.The debris is input synchronously with the airflow at the collection port, and the input debris enters the spiral pipe. During the movement of the spiral pipe, the debris slides along the outer side of the inner wall of the spiral pipe. When the debris in different states and the friction particles contact, the friction forces are different. The debris tends to be dispersed due to the friction force difference. The debris is polished by the friction particles in the spiral pipe, and the spikes on the surface of the debris are relatively smooth. The debris with fewer spikes is polished faster and is discharged from the spiral pipe first, while the debris with more spikes is polished relatively slowly and the discharge speed lags behind. The concentrated debris is dispersed in a relatively long output range after passing through the spiral pipe, and the spikes are also polished to be relatively smooth. The polished debris enters the separation sleeve. The debris is selected by the screening net, and the debris with large particles is intercepted. The small-particle debris polished by the polishing process is input into the gap between the drill hole and the threaded column. The airflow is guided in the annular flow direction when passing through the annular threaded channel, and the airflow rotates. The centrifugal force generated by the rotating airflow makes the small-particle debris polished after passing through the drill hole slide along the inner wall of the drill hole. The burrs remaining on the inner wall of the drill hole fall off under the impact of the small-particle debris. The roots of part of the remaining debris are gradually loosened under the impact of the small-particle debris, and finally fall off. After the drill hole is cleaned, two groups of micro air pumps input the airflow at the same time, the automatic door is opened, and the debris is concentrated and discharged into the lower cavity along with the airflow. The collection assembly of the present application processes the drill hole in a debris circulation mode, and improves the smoothness of the drill hole position.

The lifting mechanism is a conventional technical means in the field, and the specific structure is not described. Under the action of the lifting mechanism, the first lifting frame and the second lifting frame can freely ascend and descend. The translation module drives the translation plate to move horizontally. When the translation plate moves above the feeding table, the first lifting frame descends under the drive of the lifting mechanism, the fixed jaw clamps the linear guide rail, the lifting mechanism drives the first lifting frame to ascend, the translation module drives the translation plate to move to the reset position, the translation plate reaches above the fixed frame, the first lifting frame descends, the linear guide rail is placed on the fixed frame, at this time, the first lifting frame ascends, the second lifting frame descends, and the pushing cylinder synchronously pushes the linear guide rail at multiple positions to ensure that the linear guide rail and the protruding block are completely attached. The pushing cylinder is a double-head cylinder, which can be used to push the protruding block on both sides.

[0013] Further, the fixed frame is further provided with a setting hole, a mounting cavity, and a clamping pin, the mounting cavity is embedded with an ejection cylinder at the bottom, the output shaft of the ejection cylinder is provided with a flush plate, the clamping pin is fixedly connected with the flush plate, the clamping pin is provided in multiple roots, and the multiple roots of the clamping pin are uniformly distributed along the flush plate, one end of the setting hole is communicated with the mounting cavity, the other end of the setting hole extends to the upper surface of the fixed frame, and the clamping pin is slidingly connected with the setting hole. When the guide rail is placed on the fixed frame, the pushing cylinder pushes the guide rail to translate, one side of the guide rail is pushed against the protruding block, at this time, the ejection cylinder drives the flush plate to ascend, the flush plate drives the clamping pin to extend along the setting hole, the position of the setting hole is located on the side of the guide rail away from the protruding block, and the setting hole and the guide rail have a partially overlapping area. When the clamping pin extends, the guide rail is limited from the other side of the guide rail, the tip of the clamping pin is tapered, and a hard rubber sleeve is arranged on the surface of the clamping pin. In the process of extending the clamping pin, the side of the clamping pin close to the guide rail will gradually generate a pressing force on the guide rail. Under the action of the pressing force, the hard rubber sleeve on the surface of the clamping pin is flattened, the guide rail is pressed, the resistance of the guide rail to horizontal and vertical movement is increased, and the stability of the guide rail is further improved.

[0014] Compared with the prior art, the drilling station of the present application converts the heat accumulated in the single drilling process into the energy of liquid evaporation, and transfers the evaporation gas flow, so that the heat at the drilling position is quickly transferred, avoiding the accumulation of local heat. After the drilling is completed, the drilling station is maintained by a stable moving distance, so that the evaporation gas flow can be fully heat-exchanged with the external gas flow, and the evaporation gas flow can be liquefied faster. The drilling station separates the heat absorption and heat dissipation for the drilling process and the transfer process, extends the heat circulation in the short drilling process to the entire operation process of the drilling station, reduces the heat dissipation pressure during drilling, and provides protection for the operation of the drilling equipment. The collection assembly of the present application processes the drilling by means of debris circulation, improves the smoothness of the drilling position, and disperses the debris in a longer output range under the processing of the spiral pipe. On the other hand, the sharp spikes are also relatively smooth. The polishing and falling of large debris increases the total amount of small particle debris, and the distribution of debris avoids the concentrated impact of debris on the drilling position, but rather continuously processes the drilling with a small number of debris, avoiding damage to the drilling position. The processing of the debris also improves the safety of subsequent collection, avoiding sharp debris scratching the rest of the equipment. BRIEF DESCRIPTION OF DRAWINGS

[0028] As shown in the drawings, Figure 8As shown, the drilling station 434 includes a reducer 4341, a cover 4342, a drill bit 4343, a dispersion exhaust pipe 4344, an extrusion plate 4345, an extrusion spring 4346, a connecting channel 4347, a fixed disc 4348, the reducer 4341 is fixedly connected with the rotating motor 433 at one end, the reducer 4341 is fixedly connected with the cover 4342 at the other end, the input end of the reducer 4341 is fixedly connected with the output shaft of the rotating motor 433, the output end of the reducer 4341 is fixedly connected with the drill bit 4343, the dispersion exhaust pipe 4344 is fixed inside the cover 4342, the bottom of the cover 4342 is provided with heat dissipation fins, the heat conduction surface of the heat dissipation fins is connected with the dispersion exhaust pipe 4344, the dispersion exhaust pipe 4344 is connected with the connecting channel 4347, the connecting channel 4347 is connected with the fixed disc 4348, the fixed disc 4348 is fixedly connected with the cover 4342, the fixed disc 4348 is rotatably connected with the drill bit 4343, the drill bit 4343 is rotatably connected with the cover 4342, the drill bit 4343 is provided with a U-shaped tube inside, the U-shaped tube is arranged on the side of the drill bit 4343 away from the reducer 4341, the two ends of the U-shaped tube are communicated with the fixed disc 4348, the extrusion plate 4345 is slidably connected with the dispersion exhaust pipe 4344, one end of the extrusion spring 4346 is fixedly connected with the inner wall end surface of the dispersion exhaust pipe 4344, the other end of the extrusion spring 4346 is fixedly connected with the extrusion plate 4345. The rotating motor 433 drives the reducer 4341 to rotate, the reducer 4341 drives the drill bit 4343 to rotate, the drill bit 4343 drills holes in the linear guide rail, the U-shaped tube is filled with a liquid with a relatively low boiling point, and the specific type of the liquid is selected according to the working temperature of the drill bit, and it is required to ensure that the temperature inside the U-shaped tube is higher than the boiling point of the liquid during the working process of the drill bit 4343. The selection of the type of the liquid belongs to the conventional technical means of those skilled in the art, and is not limited here. During the drilling process, the temperature of the liquid rises, part of the liquid evaporates, the evaporated gas pushes the extrusion plate 4345 inside the dispersion exhaust pipe 4344, the extrusion plate 4345 pushes the extrusion spring 4346 to contract, the evaporated gas enters the dispersion exhaust pipe 4344, the dispersion exhaust pipe 4344 is arranged to have a volume much larger than that of the U-shaped tube, and the concentrated heat output during the drilling process is converted into the internal energy of the gas and stored in the dispersion exhaust pipe 4344. Since the linear guide rail takes a short time to drill a single hole and a large number of holes, a certain time of transfer process will occur during the drilling process. The present application sets the drilling sequence as follows: the first hole is drilled at one end of the linear guide rail, the second hole is drilled at the middle position of the linear guide rail, the third hole is drilled at the extension position of the first hole to the second hole, the fourth hole is drilled at the extension position of the second hole to the end of the linear guide rail away from the first hole, and the subsequent drilling process repeats the step. The drilling sequence makes the moving distance of the drilling station 434 relatively long after each drilling, and the moving distance is the same each time.The heat dissipation fins and the external airflow are in full contact during the movement of the drilling station 434, which disperses and timely removes the heat inside the exhaust pipe 4344. The setting direction of the heat dissipation fins is the same as the moving direction of the drilling station 434, which is more conducive to the flow of the airflow. After the evaporation airflow is cooled, it is liquefied again and flows back to the U-shaped pipe under the pushing of the extrusion plate 4345. The drilling station 434 of the present application converts the accumulated heat in the single drilling process into the energy of the liquid evaporation, and transfers the evaporation airflow. The heat at the drilling position is quickly transferred, avoiding the accumulation of local heat. After the drilling is completed, the drilling station maintains a stable moving distance, so that the evaporation airflow can be fully heat-exchanged with the external airflow, and the evaporation airflow can be liquefied faster. The drilling station 434 separates the heat absorption and heat dissipation according to the drilling process and the transfer process, and extends the heat circulation in the short drilling process to the entire operation process of the drilling station 434, thereby reducing the heat dissipation pressure during drilling and providing protection for the operation of the drilling equipment.

[0029] As shown in Figure 8 , the drilling head 4343 is also provided with a detection channel 43431 inside. The detection channel 43431 is provided with a detection plate 43432 and a detection spring 43433 inside. The detection plate 43432 and the detection channel 43431 are in sliding connection. One end of the detection spring 43433 is in fastening connection with the detection plate 43432, and the other end of the detection spring 43433 is in fastening connection with the inner wall end face of the detection channel 43431. One end of the detection channel 43431 away from the speed reducer 4341 is filled with detection gas, and the other end of the detection channel 43431 close to the speed reducer 4341 is provided with a position sensor. When abnormal temperature accumulation occurs during the drilling process, the heat dissipation capacity cannot meet the demand. At this time, the temperature is out of limit. In the case of temperature out of limit, the detection gas inside the detection channel expands out of limit, which pushes the detection plate to move past the position sensor. The position sensor outputs a signal, and the propulsion module 431 retreats. After the temperature drops, the detection spring 43431 pushes the detection plate 43432 to pass the position sensor again. The position sensor outputs a signal again, and the propulsion module 431 extends again after a set delay, and the drilling head 4343 continues to work.

A micro air flow pump is arranged on the pipeline between the separation sleeve 54 and the spiral pipe 53, and another group of micro air flow pumps are arranged on the pipeline between the separation sleeve 54 and the temporary storage slot. After the guide rail is punched, the lifting cylinder body 52 pushes the lifting strip 51 to extend, the telescopic rod 55 pushes the threaded column 56 to extend into the punched hole on the guide rail, the telescopic mechanism in the telescopic rod 55 is a conventional technical means in the field, and the specific structure is not described. The micro air flow pump starts to operate, and the air flow direction is set to draw air flow from the collecting opening and output gas from the temporary storage slot.The debris is input synchronously with the airflow at the collection port, and the input debris enters the spiral pipe 53. During the movement of the debris in the spiral pipe 53, the debris slides forward along the outer side of the inner wall of the spiral pipe 53. When the debris in different states and the friction particles are in contact, the friction forces are different. The debris tends to be in a dispersed state due to the friction force difference. The debris is polished by the friction particles in the spiral pipe 53, and the spikes on the surface of the debris are relatively smooth. The debris with fewer spikes is polished faster and is discharged from the spiral pipe 53 first, while the debris with more spikes is polished relatively slowly and the discharge speed lags behind. The concentrated debris is dispersed in a relatively long output range after passing through the spiral pipe, and the spikes are also polished to be relatively smooth. The polished debris enters the separation sleeve. The debris is selected by the screening net, and the debris with large particles is intercepted. The small-particle debris polished is input into the gap between the drill hole and the threaded column 56. When the airflow passes through the annular threaded channel, the airflow is guided in the annular flow direction, and the airflow rotates. The centrifugal force generated by the rotating airflow makes the small-particle debris polished slide along the inner wall of the drill hole. The burrs remaining on the inner wall of the drill hole are detached under the impact of the small-particle debris. The roots of part of the remaining debris are also gradually loosened under the impact of the small-particle debris, and finally fall off. After the drill hole is cleaned, two groups of micro air pumps input the airflow simultaneously, the automatic door is opened, and the debris is concentrated and discharged into the lower cavity along with the airflow. The collection assembly 5 of the present application processes the drill hole in a debris circulation manner, and improves the smoothness of the drill hole position.

[0031] As shown in Figure 1 , Figure 7 , the collection assembly 5 further includes a conveyor belt 58 and a collection bin 59. The conveyor belt 58 is arranged at the bottom of the lower cavity 32 and is tightly connected with the lower cavity 32. The bottom of the covering sleeve is directed to the center position of the conveyor belt 58. The collection bin 59 is arranged on one side of the main machine box 2 and is tightly connected with the ground. One end of the conveyor belt 58 extends into the collection bin 59. The debris entering the lower cavity 32 falls on the conveyor belt 58. The conveyor belt 58 operates to move the debris and output the debris to the collection bin 59 for storage. The collection bin 59 is regularly cleaned.

[0032] As shown in Figure 5As shown, the carrying assembly 6 includes a support truss 61, a translation module 62, a translation plate 63, a first lifting frame 64, a second lifting frame 65, a fixed clamping jaw 66, and a pushing cylinder 67. One end of the support truss 61 is fixedly connected to the ground, and the other end is fixedly connected to the main box 2. The translation module 62 is fixedly connected to the support truss 61. The translation plate 63 is fixedly connected to the movable end of the translation module 62. The first lifting frame 64 and the second lifting frame 65 are slidingly connected to the translation plate 63. The first lifting frame 64 and the second lifting frame 65 are respectively located on both sides of the translation plate 63. The translation plate 63 and the first lifting frame 64 are provided with a lifting mechanism. The translation plate 63 and the second lifting frame 65 are provided with a lifting mechanism.

The pushing cylinder 67 is fixedly connected to the bottom of the second lifting frame 65. The pushing cylinder 67 is provided with multiple groups, which are evenly distributed along the bottom of the second lifting frame 65.

[0033] As Figure 6As shown, the fixed frame 3 is also provided with a setting hole 35, a mounting cavity 36, a clamping pin 37, the bottom of the mounting cavity is embedded with an ejection cylinder 38, the output shaft of the ejection cylinder 38 is provided with a flush plate, the clamping pin 37 and the flush plate are tightly connected, the clamping pin 37 is provided with a plurality of clamping pins 37, the plurality of clamping pins 37 are uniformly distributed along the flush plate, one end of the setting hole 35 is communicated with the mounting cavity 36, the other end of the setting hole 35 extends to the upper surface of the fixed frame 3, the clamping pin 37 and the setting hole 35 are slidingly connected. When the guide rail is placed on the fixed frame 3, the push cylinder 67 pushes the guide rail to translate, one side of the guide rail is pushed against the protruding block 34, at this time the ejection cylinder 38 drives the flush plate to move upwards, the flush plate drives the clamping pin 37 to extend along the setting hole 35, the position of the setting hole 35 is located on the side of the guide rail away from the protruding block 34, and the setting hole 35 and the guide rail have a partially overlapping area. When the clamping pin 37 extends, the guide rail is limited from the other side, the tip of the clamping pin 37 is tapered, and a hard rubber sleeve is arranged on the surface of the clamping pin 37. In the process of extending the clamping pin 37, the side of the clamping pin 37 close to the guide rail will gradually generate extrusion force on the guide rail. Under the action of the extrusion force, the hard rubber sleeve on the surface of the clamping pin 37 is crushed, the guide rail is subjected to pressure, the resistance of the guide rail to horizontal and vertical movement is increased, and the stability of the guide rail is further improved.

[0034] The working principle of the present application is as follows: the translation module 62 drives the translation plate 63 to move horizontally, when the translation plate 63 moves above the feeding table 1, the first lifting frame 64 moves downward under the drive of the lifting mechanism, the fixed clamping jaw 66 clamps the linear guide rail, the lifting mechanism drives the first lifting frame 64 to move upward again, the translation module 62 drives the translation plate 63 to move back to the original position, and the translation plate 63 reaches above the fixed frame, and the first lifting frame 64 moves downward to place the linear guide rail on the fixed frame 3. The first moving module 41 drives the moving table 42 to translate, the moving table 42 drives the advancing module 431 to translate, and the advancing module 431 drives the drilling table 434 to drill holes in the guide rail. The drill bit 4343 drills holes in the linear guide rail, the liquid temperature rises, part of the liquid evaporates, the evaporated gas pushes the extrusion plate 4345 inside the dispersion exhaust pipe 4344, the extrusion plate 4345 pushes the extrusion spring 4346 to contract, and the evaporated gas enters the dispersion exhaust pipe 4344. After drilling, the drilling table moves, and the heat dissipation fins and the external airflow are in full contact during the movement of the drilling table 434, so that the heat in the dispersion exhaust pipe 4344 is promptly removed, and the evaporated gas is liquefied again under the push of the extrusion plate 4345 and flows back to the U-shaped pipe. After the drilling of the guide rail is completed, the lifting cylinder 52 drives the lifting strip 51 to extend, and the telescopic rod 55 drives the threaded column 56 to extend into the drilled hole of the guide rail, so as to clean and collect the debris at the drilling position. The collected debris enters the lower layer 32, and then falls onto the conveyor belt 58. The conveyor belt 58 operates to drive the debris to move, so that the debris is concentrated and output to the collection bin 59 for storage. After the debris is collected, the guide rail is moved by the conveying assembly 6 and output to the feeding table 1.
