Description
Technical Field
[0001] The invention relates to the technical field of hole drilling equipment, in particular to a hole drilling equipment for a housing of a car heater. Background Art
[0002] In actual use, the housing of the car heater needs to be connected and fixed to many parts of the heater, such as the motor, fan, air duct and body structure. In order to ensure that the heater can work stably during the operation of the car and will not be displaced or loosened due to factors such as vibration, which will affect the normal operation of the heater and even cause safety hazards, connection holes are usually drilled on the edge of the heater housing to facilitate the subsequent assembly of the heater itself and the connection with other parts of the car.
[0003] However, existing drilling equipment has some prominent problems when drilling holes in heater housings. Due to high-speed drilling friction between the drill bit and the housing during the drilling process, a certain amount of debris will inevitably be generated. These debris will fly around during drilling. On the one hand, it is very likely to have a serious impact on the accuracy of subsequent workpiece drilling. If the situation is more serious, it will also cause damage to the drilling equipment itself, reduce the service life of the equipment, and increase maintenance costs. On the other hand, the flying debris will also pollute the processing environment, affect the cleanliness of the workshop, increase the difficulty of cleaning, and may even pose a potential threat to the health of operators.
[0004] In addition, the large amount of heat generated by high-speed friction during the drilling process cannot be ignored. This heat will be transferred to the inside of the workpiece, affecting the internal stress distribution of the workpiece, causing the workpiece to deform after processing, reducing product quality, failing to meet strict assembly requirements, and having a negative impact on the reliability of the entire car heater system. Therefore, those skilled in the art have proposed a drilling processing device for the housing of a car heater to solve the above-mentioned technical problems. Summary of the invention

Heating wires are arranged on the annular rods. A slot is formed in the middle part of the rear side of the collection box, and a lifting seat is slidably connected in the slot.
[0014] Working principle: When drilling the automobile heater housing, the fixed immersion mechanism is started first. The operator first flips and opens the rotating pressing plate on the fixed plate, and then places the workpiece of the automobile heater housing to be processed into the fixing hole. The outer processing part of the workpiece is fixed through the positioning groove on the fixed plate. Through the combined use of the fixing hole and the positioning groove, the preliminary fixing before processing the heater housing workpiece is completed. After the operator finishes placing the heater housing workpiece, the operator rotates and resets the rotating pressing plate on the fixed plate. After the rotating pressing plate is reset, the rubber pad at its bottom fits with the surface of the workpiece in the positioning groove and deforms under the influence of the pressure on the upper part of the rotating pressing plate, so as to fill and fix the gap between the workpiece in the positioning groove and its inner wall, thus completing the secondary fixing before processing the heater housing workpiece. After multiple fixing processes, the through holes at various positions on the positioning groove, the rubber pad and the positioning fitting groove are in an overlapping state. Then, the operator controls the electric cylinders at various positions on the base to start through the control device. When the electric cylinders start, the rods on them contract. While the rods of the electric cylinders contract, they drive the fixed plate and the fixed workpiece on them to slowly immerse into the water in the liquid storage cavity. After the bottom of the fixed plate contacts the top of the bottom support seat in the liquid storage cavity, the rods on the electric cylinders stop contracting, so that the heater housing workpiece on the fixed plate is completely immersed in the water in the liquid storage cavity, thus completing the multiple fixing and immersion processes before drilling the heater housing workpiece;Then the drilling displacement mechanism is activated. The staff controls the extension arm equipped with a multi-head drill on the displacement adjustment seat to move downward through the control device. While the extension arm moves downward, the multi-head drill on it moves downward synchronously, and the multiple drill bits on the multi-head drill enter the corresponding through holes respectively. When the multiple drill bits enter the through holes, the drilling work on the heater fan housing is completed. And when the multi-head drill moves downward, when the multi-head drill enters the positioning fitting groove on the rotating pressing plate, the drilling process of the workpiece stops. After the drilling process of the workpiece is completed, the staff controls the extension arm on one side and the multi-head drill on it to move upward and reset through the control device. Then the stepping motor in the base is activated. While the rotating shaft of the stepping motor rotates, it drives the rotating seat on it to rotate synchronously. While the rotating seat rotates, it drives the extension arm and the pneumatic suction cup on it to transfer to the upper position of the fixing plate. At this time, the staff controls the rod of the electric cylinder to be pushed out through the control device. While the rod of the electric cylinder is pushed out, it drives the fixing plate and the heater fan housing workpiece after drilling on it to move upward synchronously, so that the workpiece after drilling moves out of the water surface in the liquid storage cavity. Then the staff flips and opens the rotating pressing plate on the fixing plate. After that, the staff controls the extension arm and the pneumatic suction cup at the corresponding position on the displacement adjustment seat to move downward, and adsorbs and fixes the workpiece in the fixing hole through the pneumatic suction cup. After the adsorption and fixation are completed, the extension arm and the pneumatic suction cup at the corresponding position move upward and reset. While the pneumatic suction cup moves upward and resets, it drives the workpiece adsorbed and fixed at its bottom to reset synchronously. After that, the stepping motor in the base is started again. While the rotating shaft of the stepping motor rotates, it drives the rotating seat, the displacement adjustment seat, the extension arm and the workpiece on the pneumatic suction cup to move to the position of the collection box. When the workpiece after drilling moves to the upper part of the collection box, the pneumatic suction cup releases the fixation of the workpiece, so that the workpiece falls into the collection box, thus completing the drilling of the heater fan housing and the displacement process after drilling;Meanwhile, the simultaneous cyclic dandruff removal mechanism is activated. During the process of drilling the workpiece of the heater housing, the air pump on the liquid storage tank is started. The air pump injects gas into the bottom of the liquid storage cavity of the liquid storage tank through the connecting pipe, so that the water in the liquid storage cavity becomes a state of simulated boiling, which enables the deposited debris at the bottom of the liquid storage cavity to flow along with the water flow and not deposit at the bottom of the liquid storage cavity. Then, the transfer pump on the liquid storage tank is started. The transfer pump pumps the water in the liquid storage cavity through the connecting pipe and discharges it into the installation box. The water entering the installation box first buffers the impact force of the water flow through the filter iron screen inside it and simultaneously filters some larger-sized debris in the water. Then, the water filtered through the filter iron screen is further filtered multiple times through the filter cotton board, so as to completely filter out the debris in the water. Finally, the water after multiple treatments falls to the bottom of the installation box and returns to the liquid storage cavity for reuse, thereby completing the cyclic and multiple filtration treatment of the debris generated during drilling in the water. Meanwhile, the drying treatment mechanism is activated. After the pneumatic suction cup releases the fixation of the workpiece after the drilling treatment, the workpiece adsorbed at the bottom of the pneumatic suction cup drops. After the workpiece drops into the collection box, the limit guiding rods on the mounting disc seat are respectively inserted into the corresponding drill holes of the workpiece. During the dropping process of the workpiece, the sponge layer on the limit guiding rod rubs against the inner wall position of the drill hole of the workpiece, so as to remove the metal burrs remaining at the drill hole position of the workpiece. After a certain number of workpieces accumulate in the collection box, the drive motor in the collection box is started. While the rotating shaft of the drive motor rotates, it drives the mounting disc seat thereon to rotate synchronously. While the mounting disc seat rotates, it drives the limit guiding rods and the fixed workpieces thereon to rotate synchronously, so as to separate the liquid remaining on the surface of the workpiece. The heating wire on the annular rod is electrified to generate heat, and the heat is conducted to the workpieces in the collection box, so as to evaporate and dry the moisture remaining on the surface of the workpieces in the collection box. After the drying treatment of the workpieces in the collection box is completed, the operator pulls the lifting seat in the slot, so that the lifting seat moves upward in the slot. While the lifting seat moves upward, it withdraws the workpieces processed in the collection box, thereby completing the drying treatment of the heater housing after the drilling treatment.;
[0015] The present invention provides a drilling processing device for an automobile heater housing. It has the following beneficial effects: 1. The present invention greatly improves the quality and efficiency of drilling processing of automobile heater housing by adding and setting a fixed immersion mechanism. Before the drilling operation, the mechanism adopts multiple fixing methods to firmly stabilize the heater housing, greatly enhancing the stability of the workpiece during the processing process, and providing a strong guarantee for accurate drilling. At the same time, the mechanism innovatively immerses the workpiece in water for drilling, which has multiple advantages. On the one hand, it effectively avoids the splashing of debris, prevents damage to the processing equipment, prolongs the service life of the equipment, maintains the cleanliness of the processing environment, and reduces the cleaning cost. On the other hand, the cooling effect of water can significantly reduce the heat generated by friction during drilling, reduce the impact on the internal stress of the workpiece, avoid deformation of the workpiece after processing, and improve the product qualification rate.
[0016] 2. The present invention increases and sets a drilling shifting mechanism. When drilling holes on the automobile heater housing, the mechanism can carry out drilling operations on multiple positions of the heater housing at the same time due to its unique design, which greatly shortens the processing time of a single workpiece, greatly improves the drilling efficiency, and meets the needs of large-scale production. After the drilling is completed, the mechanism can automatically shift the processed products. This processing method not only reduces the labor intensity of the staff in carrying the workpiece and saves labor costs, but also minimizes the risk of damage to the workpiece due to bumps, drops and other factors during manual transportation, thereby improving the integrity and qualified rate of the product.
[0017] 3. The present invention adds and sets a circulating chip removal mechanism. When drilling a hole in the car heater housing, gas is injected into the water with the help of an air pump, so that the water in the liquid storage chamber is in a simulated boiling state, which effectively prevents debris from settling on the bottom of the water, provides convenience for subsequent circulation treatment, and avoids debris accumulation affecting equipment operation. At the same time, the mechanism can circulate and filter the debris generated by drilling. This treatment method can not only remove the debris in the water in time to prevent its residue from affecting the drilling accuracy of subsequent workpieces and reduce the defective rate, but also avoid the wear of the equipment by the debris, extend the service life of the equipment, and ensure the efficient and stable drilling operation.
[0018] 4. The present invention adds and sets a drying treatment mechanism. After the drilling process of the automobile heater housing is completed, the mechanism can not only remove the metal burrs remaining in the drilled hole during the falling process of the workpiece, thereby improving the accuracy of the heater housing during assembly, but also remove the residual liquid on the surface of the workpiece through a multi-process coordination method to prevent the residual liquid on the surface of the workpiece from affecting it, thereby significantly improving the quality stability of the product and effectively reducing the after-sales maintenance cost.

Detailed implementation manners
[0021] Next, in combination with the specification drawings of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to the attached Figure 1 -attached Figure 2 , the embodiment of the present invention provides a drilling processing device for an automobile heater housing, including a base 1, which is used as the basic component of the overall device and is used for assembling and carrying each processing mechanism and its subordinate structural components; Please refer to the attached Figure 3 -attached Figure 4 , a fixed immersion mechanism, which is arranged on the top of the base 1 and is used for fixing the automobile heater housing to be drilled and immersing it in a liquid for processing; The fixed immersion mechanism includes a fixed plate 5. In the middle of the top end of the base 1, there is a fixed plate 5. In the middle of the top end of the fixed plate 5, there is a positioning groove 25. In the middle of the bottom end of the positioning groove 25, there is a fixing hole 23. On both sides of the middle of the top end of the fixed plate 5, there are rotatably connected rotating pressing plates 4. On one side of the middle of the top end of each rotating pressing plate 4, there is a positioning fitting groove 21. On one side of the middle of the bottom end of each rotating pressing plate 4, there is a rubber pad 24. Through holes 22 are opened at the corners of the positioning groove 25, the rubber pad 24, and the positioning fitting groove 21. At the four corners of the top end of the base 1, there are electric cylinders 14. The top ends of the rod bodies of the electric cylinders 14 are respectively connected to the four corners of the bottom end of the fixed plate 5.
[0023] When the fixed immersion mechanism is started, the staff first flips and opens the rotating pressing plate 4 on the fixed plate 5, and then the staff places the automotive heater housing workpiece to be processed into the fixing hole 23. The external processing part of the workpiece is fixed through the positioning groove 25 on the fixed plate 5. Through the combined use of the fixing hole 23 and the positioning groove 25, the preliminary fixing treatment before processing the heater housing workpiece is completed.
[0024] After the staff finishes placing the heater housing workpiece, the staff rotates the rotating pressing plate 4 on the fixed plate 5 to reset it. After the rotating pressing plate 4 is reset, the rubber pad 24 at its bottom fits with the surface of the workpiece in the positioning groove 25 and deforms under the influence of the pressure on the upper part of the rotating pressing plate 4, so as to fill and fix the gap between the workpiece inside the positioning groove 25 and its inner wall, thereby completing the re-fixing treatment before processing the heater housing workpiece. After multiple fixing treatments, the through holes 22 at various positions on the positioning groove 25, the rubber pad 24, and the positioning fitting groove 21 are in an overlapping state.
[0025] The fixed immersion mechanism further includes a liquid storage tank 13. In the middle of the top end of the base 1, there is a liquid storage tank 13. In the middle of the inner side of the liquid storage tank 13, there is a liquid storage cavity 20, and the liquid storage cavity 20 is filled with water. On both sides of the middle of the bottom end of the liquid storage cavity 20, there are fixedly connected bottom support seats 36. On both sides of the middle of the top end of each bottom support seat 36, there are extension holes 34. On both sides of the middle of the outer wall of each bottom support seat 36, there are equidistantly arranged a plurality of inclined discharge grooves 35, and the inclined discharge grooves 35 are respectively communicated with the inside of the corresponding extension holes 34 on the same side.
[0026] After that, the staff controls the electric cylinders 14 at various positions on the base 1 to start through the control device. While the electric cylinders 14 are starting, the rod bodies thereon contract. While the rod bodies of the electric cylinders 14 contract, the fixing plates 5 thereon and the workpieces after fixation are driven to slowly immerse into the water in the liquid storage cavity 20. After the bottom of the fixing plate 5 contacts the top of the bottom support seat 36 in the liquid storage cavity 20, the rod bodies on the electric cylinders 14 stop contracting, so that the heater housing workpieces on the fixing plates 5 are completely immersed in the water within the liquid storage cavity 20, thereby completing the multiple fixing and immersion treatment before drilling the heater housing workpieces.
[0027] Please refer to the attached Figure 5 - attached Figure 6 , the drilling and displacement mechanism, which is arranged at the rear of the base 1 and is used for drilling the automotive heater housing after being processed by the fixing and immersion mechanism and for displacement treatment after drilling; The drilling and displacement mechanism includes a base 12. The middle part of the rear side of the base 1 is provided with a base 12. The middle part of the top end of the base 12 is rotatably connected with a rotating seat 19. The middle part of the inner side of the base 12 is provided with a stepping motor 26, and the output end of the stepping motor 26 is connected with the middle part of the rotating seat 19. The middle part of the top end of the rotating seat 19 is fixedly connected with a displacement adjustment seat 7. The middle parts on both sides of the displacement adjustment seat 7 are provided with extendable arms 8 that can move up and down. One end of an extendable arm 8 away from the displacement adjustment seat 7 is provided with a multi-head drill 6, and the other end of the other extendable arm 8 away from the displacement adjustment seat 7 is provided with a pneumatic suction cup 9.
[0028] When the drilling and displacement mechanism is started, the staff controls the extendable arm 8 with the multi-head drill 6 installed on the displacement adjustment seat 7 to move down through the control device. While the extendable arm 8 is moving down, the multi-head drill 6 thereon moves down synchronously, and the multiple drill bits on the multi-head drill 6 respectively enter into the corresponding through holes 22. While the multiple drill bits enter into the through holes 22, the drilling work of the heater housing is completed. And when the multi-head drill 6 moves down, when the multi-head drill 6 enters into the positioning fitting groove 21 on the rotating pressing plate 4, the drilling treatment of the workpiece is stopped.
[0029] During the drilling process, since the fixing plate 5 and the workpiece thereon are both in the water in the liquid storage cavity 20, part of the debris generated during the drilling process is dispersed in the water in the liquid storage cavity 20 and mixed with it, and the other part of the debris enters into the extension holes 34 in the bottom support seat 36 through the action of the drill bits. Along with the continuous flow of the water in the liquid storage cavity 20, the debris in the bottom support seat 36 is discharged through the inclined discharge grooves 35 on both sides of it and enters into the liquid storage cavity 20 to be mixed with the water. Moreover, during the drilling process, the heat generated by the friction between the drill bits and the workpiece is conducted into the water for heat dispersion treatment.
[0030] After the drilling process of the workpiece is completed, the staff controls the extension arm 8 on one side and the multi-head drill 6 thereon to move up and reset through the control device. Then, the stepping motor 26 inside the base 12 is started. While the rotating shaft of the stepping motor 26 rotates, it drives the rotating seat 19 thereon to rotate synchronously. While the rotating seat 19 rotates, it drives the extension arm 8 and the pneumatic suction cup 9 thereon to move to the upper position of the fixing plate 5. At this time, the staff controls the rod on the electric cylinder 14 to push out. While the rod on the electric cylinder 14 pushes out, it drives the fixing plate 5 and the heater fan housing workpiece after drilling thereon to move up synchronously, so that the workpiece after drilling moves out of the water surface in the liquid storage cavity 20. Then, the staff flips and opens the rotating pressing plate 4 on the fixing plate 5. After that, the staff controls the extension arm 8 and the pneumatic suction cup 9 at the corresponding position on the displacement adjustment seat 7 to move down, and adsorbs and fixes the workpiece in the fixing hole 23 through the pneumatic suction cup 9.
[0031] After the adsorption and fixation are completed, the extension arm 8 and the pneumatic suction cup 9 at the corresponding position move up and reset. While the pneumatic suction cup 9 moves up and resets, it drives the workpiece adsorbed and fixed at its bottom to reset synchronously. Then, the stepping motor 26 inside the base 12 is started again. While the rotating shaft of the stepping motor 26 rotates, it drives the rotating seat 19, the displacement adjustment seat 7, the extension arm 8 and the workpiece on the pneumatic suction cup 9 to move to the position of the collection box 11. When the workpiece after drilling moves to the upper part of the collection box 11, the pneumatic suction cup 9 releases the fixation of the workpiece, so that the workpiece falls into the collection box 11, thereby completing the drilling of the heater fan housing and the displacement process after drilling.
[0032] Please refer to the attached Figure 2 -attached Figure 3 and attached Figure 7 and, a circulating chip removal mechanism, which is arranged on the upper part of the base 1 and is used for circulating filtration treatment of the chips generated during the drilling process of the automotive heater fan housing; The circulating chip removal mechanism includes an air pump 16. The air pump 16 is arranged at the lower middle part at the rear side of the liquid storage tank 13. One end of the exhaust port of the air pump 16 is connected to one end of a connecting pipe, and the other end of the connecting pipe penetrates through the liquid storage tank 13 and extends to the bottom of the liquid storage cavity 20.
[0033] When the circulating chip removal mechanism is started, during the drilling process of the heater fan housing workpiece, the air pump 16 on the liquid storage tank 13 is started. The air pump 16 injects gas into the bottom of the liquid storage cavity 20 of the liquid storage tank 13 through the connecting pipe, so that the water in the liquid storage cavity 20 becomes a state of simulated boiling, and the deposited chips at the bottom of the liquid storage cavity 20 can follow the water flow and do not deposit at the bottom of the liquid storage cavity 20.
[0034] The circulating anti-dandruff mechanism further includes an installation box 2. The upper middle part of one side of the front end of the liquid storage tank 13 is provided with the installation box 2. The top of the installation box 2 is provided with a closed cover 3. The upper middle part of the inner side of the installation box 2 is provided with a filtering iron screen 28. A plurality of filtering cotton plates 27 are equidistantly arranged in the lower middle part of the inner side of the installation box 2. The lower middle part of the installation box 2 is communicated with the inside of the liquid storage cavity 20. One side of the lower middle part of the front end of the liquid storage tank 13 is provided with a delivery pump 15. The liquid inlet of the delivery pump 15 is communicated with the bottom side of the liquid storage cavity 20 through a connecting pipe. The liquid outlet of the delivery pump 15 is communicated with the upper middle part of one side of the installation box 2 through a connecting pipe.
[0035] Then, the delivery pump 15 on the liquid storage tank 13 is started. The delivery pump 15 pumps the water in the liquid storage cavity 20 through the connecting pipe and discharges it into the installation box 2. The water entering the installation box 2 first buffers the impact force of the water flow through the filtering iron screen 28 inside it, and synchronously filters some debris with larger particle sizes in the water. Then, the water filtered by the filtering iron screen 28 is further filtered multiple times by the filtering cotton plates 27, so as to completely filter out the debris in the water. Finally, the water after multiple treatments falls to the bottom of the installation box 2 and returns to the liquid storage cavity 20 for reuse, thereby completing the circulation and multiple filtering treatment of the debris generated by drilling in the water.
[0036] Please refer to the appendix Figure 8 , a drying mechanism, which is arranged at the rear of the base 1 and is used for drying the heater housing after drilling treatment.
[0037] The drying mechanism includes a collection box 11. The collection box 11 is arranged at the rear side of the base 12. The middle part of the inner bottom end of the collection box 11 is rotatably connected with an installation disc seat 30. The top of the installation disc seat 30 is fixedly connected with a plurality of limit guiding rods 10 at equal intervals. Sponge layers 32 are arranged on the outer walls of the limit guiding rods 10. The middle part of the inner bottom end of the collection box 11 is provided with a driving motor 29, and the output end of the driving motor 29 is connected with the middle part of the installation disc seat 30.
[0038] The drying treatment mechanism is activated. After the pneumatic suction cup 9 releases the fixation of the workpiece after drilling treatment, the workpiece adsorbed at the bottom of the pneumatic suction cup 9 drops. After the workpiece drops into the collection box 11, the limit guiding rods 10 on the mounting disc base 30 are respectively inserted into the corresponding drilled holes of the workpiece. During the dropping process of the workpiece, the sponge layer 32 on the limit guiding rod 10 rubs against the inner wall position of the drilled hole of the workpiece, thereby removing the metal burrs remaining at the drilled hole position of the workpiece. After a certain number of workpieces accumulate in the collection box 11, the drive motor 29 in the collection box 11 is activated. While the rotating shaft of the drive motor 29 rotates, it drives the mounting disc base 30 thereon to rotate synchronously. While the mounting disc base 30 rotates, it drives the limit guiding rods 10 and the fixed workpiece thereon to rotate synchronously, thereby separating the liquid remaining on the surface of the workpiece.
[0039] The drying treatment mechanism further includes an annular rod 31. A plurality of annular rods 31 are equidistantly arranged in the middle of the inner side of the collection box 11. Heating wires 33 are arranged on the annular rods 31. A slot 17 is opened in the middle of the rear side of the collection box 11, and a lifting seat 18 is slidably connected in the slot 17.
[0040] The heating wires 33 on the same annular rod 31 are electrified to generate heat, and the heat is conducted to the workpieces in the collection box 11, thereby evaporating and drying the moisture remaining on the surfaces of the workpieces in the collection box 11. After the drying treatment of the workpieces in the collection box 11 is completed, the staff pulls the lifting seat 18 in the slot 17, so that the lifting seat 18 moves upward in the slot 17. While the lifting seat 18 moves upward, it withdraws the workpieces that have been processed in the collection box 11, thereby completing the drying treatment of the blower housing after drilling treatment.
