Description

Technical Field

[0001] This utility model belongs to the field of shaft diameter drilling technology, specifically a device for radial drilling of motor shafts. Background Technology

[0002] Motor shafts are generally long and slender items. When machining motor shafts, especially when machining the outer circumference of the entire motor shaft, they are usually machined on a lathe. During machining, a rotary center is used to position the motor shaft. The center needs to be positioned with the help of a center hole. This requires drilling holes at both ends of the motor shaft. Drilling is generally done with a drilling machine. The workpiece is fixed on a fixture. The fixture is movable. First, a scriber is used to scribble a line on one end face of the motor shaft to determine the center point. Then, the drill bit of the drilling machine is aligned with the center point to drill a hole.

[0003] A patent with publication number CN106926017A discloses a radially adjustable circular workpiece drilling device, including a support, a workpiece clamping device, and a drilling device. The workpiece clamping device is rotatably mounted on the support via a rotating shaft, which is connected to a first drive motor via a transmission device. The drilling device includes a horizontal slide rail, a support arm slidably mounted on the horizontal slide rail, a first drive device for driving the support arm to slide along the horizontal slide rail, a vertical slide rail fixedly mounted on the support arm, a carrier plate slidably mounted on the vertical slide rail, a second drive device for driving the carrier plate to slide along the vertical slide rail, and a drilling machine fixedly mounted on the carrier plate. A drilling method using this device is also disclosed. The advantages of this invention are: the radial position of the drilling hole on the workpiece is adjusted via the horizontal guide rail; the workpiece clamping device, rotatably mounted on the support via a rotating shaft, enables drilling at different circumferential positions on the workpiece; the structure is simple and easy to operate.

[0004] In existing technologies, radial drilling devices for motor shaft machining can perform fixed drilling on motor shafts of different lengths. During operation, these devices generate a large amount of debris of varying sizes. However, the airflow from the fan used to blow away the debris remains constant. The debris generated when the drill first contacts the workpiece is very fine and light. Under the force of the powerful fan, this fine debris is thrown further and over a wider area, making it difficult to collect later. In particular, when fine debris splashes into the equipment, it can easily cause jamming and wear in precision equipment. This makes it difficult for the fan to increase its airflow as the drilling depth increases.

[0005] Therefore, a radial drilling device for motor shaft is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and solve the above-mentioned problems, a radial drilling device for motor shafts is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The radial drilling device for a motor shaft of this utility model includes a processing table and a chip blowing box fixedly installed on the inner wall of one side of the processing table. A limiting rod two is movably sleeved on the outer surface of the chip blowing box. A pressing block is fixedly connected to the outer surface of the top of the limiting rod two. Multiple sets of downward inclined air guides are fixedly connected to the outer surface of the chip blowing box. The outer surface of the limiting rod two is movably sleeved on the outer surface of the downward inclined air guides. Multiple sets of limiting support rods are fixedly connected to the inner walls on both sides of the chip blowing box. A closing plate fixedly connected to the outer surface of the limiting support rod is movably sleeved on the outer surface of the limiting support rod. A hydraulic rod is fixedly connected to the inner wall of the top of the processing table. A radial drill is fixedly connected to the output end of the hydraulic rod. A limiting sliding sleeve that movably overlaps the top surface of the pressing block is provided on the outer surface of the radial drill.

[0008] Preferably, an elastic buffer wire 2 is movably sleeved on the outer surface of the limiting support rod and disposed on the bottom surface of the closing plate, and the outer surface of the closing plate is movably fitted to the inlet edge of the downward inclined air guide.

[0009] Preferably, an air pump is fixedly installed on the outer surface of the processing table, and a chip collection box is fixedly installed on the inner wall of the processing table, which is disposed on the bottom surface of the chip blowing box.

[0010] Preferably, a mounting plate is provided on the top surface of the chip collection box and at the bottom edge of the radial drill, and a flared opening is provided on the top surface of the chip collection box and at one side edge of the mounting plate.

[0011] Preferably, a limiting rod is fixedly connected to the top surface of the chip collection box and at the back edge where the fixing plate is placed, and the inner wall of the limiting sleeve is movably sleeved on the outer surface of the limiting rod.

[0012] Preferably, an elastic buffer wire is movably sleeved on the outer surface of the limiting rod and disposed on the bottom surface of the limiting slide sleeve, and a closing door is provided on the front of the processing table.

[0013] Preferably, a sealing ring is provided on the back of the chip blowing box, and the output end of the air pump extends to the inner wall of the sealing ring.

[0014] Preferably, the front of the chip blowing box is provided with limit blocks at the upper and lower edges, and the outer surface of the second limit rod is movably sleeved on the inner wall of the limit block.

[0015] The beneficial effects of this utility model are:

[0016] This utility model provides a radial drilling device for a motor shaft. When the output end of the radial drill contacts the workpiece, the radial drill will press down the lower block, causing the limiting rod on the outer surface of the lower block to move the closing plate down on the surface of the limiting support rod. This causes the closing plate to unfold alternately from the inlet of the downward-sloping air guide. As the gap between the downward-sloping air guide and the closing plate continues to open, the gas filled inside the chip blowing box will diffuse out through the gap and impact the contact surface between the output end of the radial drill and the workpiece, thereby impacting the grinding debris to one side. As the radial drill penetrates deeper into the workpiece, the gap of the closing plate will become larger and larger, and the air force will become stronger and stronger, thus impacting the larger debris. This achieves the effect of using the radial drill to gradually increase and strengthen the air force to effectively blow away larger debris through the continuous processing between the radial drill and the workpiece.

[0017] This utility model provides a radial drilling device for a motor shaft. As the wind force increases, the debris will slide to one side under the wind. At this time, with the long flared mouth and high inlet space, the impacting debris can be guided and collected, and the debris is guided into the inside of the debris collection box. At the same time, as the drill rod of the radial drill continues to penetrate into the workpiece, the friction between the two will gradually increase, resulting in excessive heat. At this time, the gradually increasing wind force will blow at the friction point between the workpiece and the radial drill bit. The fast-flowing wind will carry away the heat source, thereby effectively reducing the heat source of the workpiece and the drill bit. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figure 1 - Figure 5 This utility model provides a radial drilling device for a motor shaft, including a processing table 11 and a chip blowing box 12 fixedly installed on the inner wall of one side of the processing table 11. A limit rod 123 is movably sleeved on the outer surface of the chip blowing box 12. A pressing block 124 is fixedly connected to the outer surface of the top end of the limit rod 123. Multiple sets of downward inclined air guides 125 are fixedly connected to the outer surface of the chip blowing box 12. The outer surface of the limit rod 123 is movably sleeved on the outer surface of the downward inclined air guides 125 to blow away chips. Multiple sets of limiting support rods 127 are fixedly connected to the inner walls on both sides of the box 12. A closing plate 126 fixedly connected to the outer surface of the limiting support rod 123 is movably sleeved on the outer surface of the limiting support rod 127. A hydraulic rod 115 is fixedly connected to the inner wall of the top of the processing table 11. A radial drill 116 is fixedly connected to the output end of the hydraulic rod 115. A limiting sliding sleeve 119 is provided on the outer surface of the radial drill 116 and movably overlaps the top surface of the lower pressure block 124.

[0028] During operation, the workpiece is placed on the surface of the fixing plate 13 and fixed. At this time, when the radial drill 116 is lowered using the hydraulic rod 115, and the output end of the radial drill 116 contacts the workpiece, the limiting sleeve 119 on the outer surface of the radial drill 116 presses down on the surface of the lower pressure block 124. This causes the limiting rod 123 on the outer surface of the lower pressure block 124 to move the closing plate 126 downwards on the surface of the limiting support rod 127. Consequently, the closing plate 126 unfolds alternately from the inlet of the downward-sloping air guide 125. The downward-sloping air guide 125 and... As the gap between the closed plates 126 expands, the gas filling the chip blowing box 12 diffuses out through the gap and impacts the contact surface between the output end of the radial drill 116 and the workpiece, thus pushing the grinding debris to one side. As the radial drill 116 penetrates deeper into the workpiece, the gap between the closed plates 126 becomes larger and the airflow becomes stronger, thereby impacting larger and larger debris. This achieves the effect of gradually increasing and strengthening the airflow to effectively blow away larger debris by utilizing the continuous penetration of the radial drill 116 into the workpiece.

[0029] Furthermore, such as Figures 1 to 5 As shown, an air pump 114 is fixedly installed on the outer surface of the processing table 11, and a chip collection box 111 is fixedly installed on the inner wall of the processing table 11, which is located on the bottom surface of the chip blowing box 12. A placement and fixing plate 13 is provided on the top surface of the chip collection box 111 and at the bottom edge of the radial drill 116. A flared mouth 113 is provided on the top surface of the chip collection box 111 and at one side edge of the placement and fixing plate 13. An elastic buffer wire 118 is movably sleeved on the outer surface of the limiting rod 117 and located on the bottom surface of the limiting sleeve 119. A closing door 112 is provided on the front of the processing table 11.

[0030] As the wind force increases, the debris will slide to one side under the wind. At this time, with the long and high inlet space of the horn 113, the impacting debris can be guided and collected, and the debris is guided into the inside of the chip collection box 111. Meanwhile, as the drill rod of the radial drill 116 continues to penetrate into the workpiece, the friction between the two will gradually increase, resulting in excessive heat. At this time, the gradually increasing wind force will blow at the friction point between the workpiece and the radial drill 116 drill bit. The fast-flowing wind will carry away the heat source, thereby effectively reducing the heat source of the workpiece and drill bit.

[0031] Furthermore, such as Figures 1 to 5As shown, an elastic buffer wire 128 is movably sleeved on the outer surface of the limiting support rod 127 and is provided on the bottom surface of the closing plate 126. The outer surface of the closing plate 126 is movably fitted to the inlet edge of the downward inclined air guide 125. A limiting rod 117 is fixedly connected to the top surface of the chip collection box 111 and located at the back edge of the fixed plate 13. The inner wall of the limiting sleeve 119 is movably sleeved on the outer surface of the limiting rod 117. A sealing ring 121 is provided on the back of the chip blowing box 12. The output end of the air pump 114 extends to the inner wall of the sealing ring 121. A limiting block 122 is provided on the front of the chip blowing box 12 and located at the upper and lower edges. The outer surface of the limiting rod 123 is movably sleeved on the inner wall of the limiting block 122.

[0032] After the radial drill 116 finishes processing, it will rise continuously under the pullback of the hydraulic rod 115. At this time, in conjunction with the reverse pushing force of the elastic buffer wire 128 on the outer surface of the limit support rod 127, the closing plate 126 is lifted, and the closing plate 126 gradually seals the entrance of the downward inclined air guide 125. The closure of the exhaust port ensures that when the employee opens the closing door 112 to take out the workpiece, some residual debris inside the processing table 11 will not be spread out by the air source. This achieves the effect of self-blowing, cooling and shutting off the air source when the workpiece is being processed.

[0033] Working principle: The workpiece is placed on the surface of the fixing plate 13 and fixed. When the radial drill 116 is lowered using the hydraulic rod 115, and the output end of the radial drill 116 contacts the workpiece, the limiting sleeve 119 on the outer surface of the radial drill 116 presses down on the surface of the lower pressure block 124. This causes the limiting rod 123 on the outer surface of the lower pressure block 124 to move the closing plate 126 downwards on the surface of the limiting support rod 127. Consequently, the closing plate 126 unfolds alternately from the inlet of the downward-sloping air guide 125. The downward-sloping air guide 125 and... As the gap between the closed plates 126 expands, the gas filling the chip blowing box 12 diffuses out through the gap and impacts the contact surface between the output end of the radial drill 116 and the workpiece, thereby pushing the grinding debris to one side. As the radial drill 116 penetrates deeper into the workpiece, the gap between the closed plates 126 becomes larger and the airflow becomes stronger, thus impacting the larger debris. This achieves the effect of gradually increasing and strengthening the airflow to effectively blow away larger debris by utilizing the continuous penetration of the radial drill 116 into the workpiece.

[0034] As the wind force increases, the debris will slide to one side under the wind. At this time, with the long and high inlet space of the horn 113, the impacting debris can be guided and collected, and the debris is guided into the inside of the chip collection box 111. Meanwhile, as the drill rod of the radial drill 116 continues to penetrate into the workpiece, the friction between the two will gradually increase, resulting in excessive heat. At this time, the gradually increasing wind force will blow at the friction point between the workpiece and the radial drill 116 drill bit. The fast-flowing wind will carry away the heat source, thereby effectively reducing the heat source of the workpiece and the drill bit.

[0035] After the radial drill 116 finishes processing, it will rise continuously under the pullback of the hydraulic rod 115. At this time, in conjunction with the reverse pushing force of the elastic buffer wire 128 on the outer surface of the limit support rod 127, the closing plate 126 is lifted, and the closing plate 126 gradually seals the entrance of the downward inclined air guide 125. The closure of the exhaust port ensures that when the employee opens the closing door 112 to take out the workpiece, some residual debris inside the processing table 11 will not be spread out by the air source. This achieves the effect of self-blowing, cooling and shutting off the air source when the workpiece is being processed.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
