Description

Technical Field

[0001] This utility model relates to the field of conduit processing equipment technology, and in particular to a conduit drilling machine. Background Technology

[0002] Medical catheters are made of relatively soft materials. When some catheters need to be punched in specific locations, the catheter is usually punched by pressing directly with a punching tool. However, the quality of the hole formed on the catheter is relatively uneven, and the punching tool needs to be pressed vertically from top to bottom to apply pressure, which is inconvenient. Utility Model Content

[0003] The purpose of this utility model is to provide a catheter drilling machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: a catheter drilling machine, comprising: a shell; an inner cylinder, vertically slidably disposed in the shell, the inner cylinder being equipped with a vertically disposed rack; a drilling shaft, rotatably disposed in the inner cylinder, the drilling shaft being equipped with a drilling tool; a drive assembly for driving the drilling shaft to rotate; a drive shaft, rotatably disposed in the shell, the drive shaft being equipped with a gear meshing with the rack; rotating the drive shaft can drive the drilling shaft to slide and drill holes through the gear and the rack.

[0005] The technical solution has at least the following beneficial effects: the driving component drives the drilling shaft to rotate, which in turn drives the drilling tool to rotate. By rotating the driving shaft, the drilling shaft moves vertically, which in turn drives the drilling tool to press against the guide tube, performing a rotary downward drilling operation on the guide tube. This makes the hole structure formed on the guide tube more uniform and of stable quality. Moreover, the downward drilling operation can be achieved by rotating the driving shaft on one side only. The operating point is low, which is convenient for manual operation and force control.

[0006] As a further improvement to the above technical solution, the drive assembly includes a drive wheel rotatably mounted on the housing and a drive sub-component for driving the drive wheel to rotate. The drive wheel has a through hole through which the punching shaft passes. The inner wall of the through hole is provided with a protrusion, and the outer side of the punching shaft is provided with a groove for the protrusion to be inserted and slid.

[0007] As a further improvement to the above technical solution, multiple protrusions are provided and distributed around the inner wall of the through hole, and multiple grooves are provided around the outer side of the drive shaft.

[0008] As a further improvement to the above technical solution, the drive component includes a motor mounted on the housing and a drive wheel mounted on the output end of the motor, and the drive wheel and the drive wheel are jointly fitted with a transmission belt.

[0009] As a further improvement to the above technical solution, a support rod is provided in the middle of the outer shell, and a base is installed at the bottom of the support rod.

[0010] As a further improvement to the above technical solution, the support rod is slidably connected to the outer shell, and the outer shell is slidably provided with a first fixing block and a second fixing block. The first fixing block and the second fixing block are threaded together with a fixing screw. The fixing screw is set in the opposite direction to the threads connecting the first fixing block and the second fixing block. Rotating the fixing screw can drive the first fixing block and the second fixing block to move closer to each other and clamp the support rod.

[0011] As a further improvement to the above technical solution, both the first fixing block and the second fixing block are provided with inclined arc surfaces that can be adapted to and press against the support rod on the side that is close to each other.

[0012] As a further improvement to the above technical solution, the base is equipped with a clamp, the clamp has a material hole, and the clamp has a positioning hole that communicates with the material hole and corresponds to the punching tool.

[0013] As a further improvement to the above technical solution, the outer shell is equipped with a first limiting block, the drive shaft is equipped with a second limiting block, and when the drilling shaft rotates to a preset position, the second limiting block abuts against the first limiting block.

[0014] As a further improvement to the above technical solution, a worm gear is rotatably mounted on the drive shaft, a worm is rotatably mounted on the housing and meshes with the worm gear, and the first limiting block is mounted on the worm gear. Attached Figure Description

[0026] Reference Figure 1-5 The conduit punching machine includes a housing 100, an inner cylinder 200, a punching shaft 300, a drive shaft 400, and a drive assembly.

[0027] A support rod 700 is inserted through the middle of the outer casing 100, and a base 710 is installed at the bottom of the support rod 700. When the base 710 is placed on the workbench, the outer casing 100 can be stably supported to a certain height to facilitate drilling operations.

[0028] The support rod 700 can slide vertically relative to the housing 100. The housing 100 is equipped with a fixing component for fixing the support rod 700. A fixing groove 110 is horizontally provided on the housing 100 near the support rod 700, and the fixing groove 110 is connected to the hole in the housing 100 through which the support rod 700 passes.

[0029] The fixing assembly includes a first fixing block 800, a second fixing block 810, and a fixing screw 820. The first fixing block 800 and the second fixing block 810 are slidably disposed in the fixing groove 110 in the horizontal direction, and the fixing screw 820 is sequentially inserted through the first fixing block 800 and the second fixing block 810, with one end of the fixing screw 820 protruding out of the outer shell 100 and forming a disc handle.

[0030] The first fixing block 800 and the second fixing block 810 are both threadedly connected to the fixing screw 820, and the threaded structures of the fixing screw 820 and the first fixing block 800 and the second fixing block 810 are respectively arranged in opposite directions, so that when the fixing screw 820 is rotated, the first fixing block 800 and the second fixing block 810 can be moved closer or further apart.

[0031] When the first fixing block 800 and the second fixing block 810 are close to each other, they can clamp the support rod 700, thereby restricting the sliding of the support rod 700 relative to the outer shell 100 and fixing the support rod 700 and the outer shell 100 relative to each other, so as to adjust the height position of the outer shell 100 on the support rod 700 and facilitate the assembly and connection of the outer shell 100 and the support rod 700.

[0032] Furthermore, both the first fixing block 800 and the second fixing block 810 have inclined arc surfaces 811 at their adjacent ends, which are adapted to and abut against the support rod 700. During the process of the first fixing block 800 and the second fixing block 810 approaching each other, the inclined arc surfaces 811 corresponding to the first fixing block 800 and the second fixing block 810 abut against and adhere to the outer wall of the support rod 700, thereby firmly clamping the support rod 700 and ensuring the stability of the outer shell 100 relative to the support rod 700. During processing, the adjacent ends of the first fixing block 800 and the second fixing block 810 can be made tapered.

[0033] The inner cylinder 200 is slidably disposed at one end of the outer shell 100 in a vertical direction. An embedded groove is provided on one side of the inner cylinder 200, and a rack 210 is embedded in the embedded groove. Mounting screws are provided at both ends of the rack 210, and the mounting screws are screwed into the bottom wall of the embedded groove of the inner cylinder 200 to facilitate the assembly of the rack 210.

[0034] A punching shaft 300 is inserted inside the inner cylinder 200, and both ends of the punching shaft 300 are rotatably mounted in the inner cylinder 200 via bearings. A punching tool 310 is detachably mounted on the bottom of the punching shaft 300. The punching tool 310 is a tool with a circular cross-section.

[0035] The drive assembly includes a drive wheel 500 and a drive sub-component. A flange ring 530 is detachably mounted on the top of the housing 100 via bolts. The drive wheel 500 is rotatably mounted within the flange ring 530 via two bearings, allowing the drive wheel 500 to rotate stably relative to the housing 100. The top of the drilling shaft 300 extends beyond the top of the drive wheel 500. An internal gear block 540 is bolted to the middle of the drive wheel 500. A through hole 501 is formed in the middle of the internal gear block 540, through which the drilling shaft 300 passes. Multiple protrusions 510 are evenly arranged in a ring around the inner wall of the through hole 501, and multiple grooves 520 are evenly arranged in a ring around the outer periphery of the drilling shaft 300. The number of protrusions 510 is the same as the number of grooves 520 and they are distributed in a one-to-one correspondence, so that the protrusions 510 are embedded in the grooves 520. When the inner cylinder 200 drives the drilling shaft 300 to slide up and down, the protrusion 510 can slide vertically in the groove 520. When the driving component drives the driving wheel 500 to rotate, the driving wheel 500 can drive the drilling shaft 300 to rotate under the embedded cooperation of the protrusion 510 and the groove 520, thereby realizing the rotary drilling operation and improving the circumferential uniformity of drilling.

[0036] The drive component includes a motor 600, a drive pulley 610, and a transmission belt 620. The motor 600 is mounted at the other end of the housing 100, and the drive pulley 610 is mounted at the output end of the motor 600; that is, the support rod 700 is positioned between the drive pulley 610 and the drive wheel 500. Both the drive pulley 610 and the drive wheel 500 have annular belt grooves on their outer circumferences. The transmission belt 620 is fitted over the drive pulley 610 and the drive wheel 500 and embedded in the belt grooves, thereby connecting the drive pulley 610 and the drive wheel 500 for transmission. Teeth can be provided on the outer circumferences of the drive pulley 610 and the drive wheel 500, and corresponding teeth are also provided on the inner side of the transmission belt 620. Both the drive pulley 610 and the drive wheel 500 are engaged with the transmission belt 620 for transmission.

[0037] In other embodiments, the driving wheel 610 and the drive wheel 500 can be directly connected by meshing teeth on their outer circumferences, or they can be connected by meshing gears in the middle. In other embodiments, the drive component can also be a drive motor, with its output end connected to the drive wheel 500, so that the drive motor directly drives the drive wheel 500 to rotate.

[0038] The drive shaft 400 is rotatably mounted in the housing 100, and the rotation center line of the drive shaft 400 is horizontal. The drive shaft 400 is equipped with a gear 410, which meshes with the rack 210. By rotating the drive shaft 400, the gear 410 can be driven to rotate, thereby pushing the rack 210 to slide, so that the inner cylinder 200 slides vertically within the housing 100 along with the rack 210. The inner cylinder 200 drives the punching tool 310 at the bottom of the punching shaft 300 to slide up and down, thereby performing a downward punching operation on the guide tube.

[0039] One end of the drive shaft 400 extends through one side of the housing 100 and is equipped with a pressing knob for easy gripping to rotate the drive shaft 400. The other end of the drive shaft 400 extends through the other side of the housing 100 and is equipped with a dial. The dial has circumferentially distributed first scale lines, and the housing 100 has a first comparison line near the dial. By comparing the first scale line with the first comparison line, the falling position of the drilling tool 310 can be indicated, so as to facilitate the operator's control over the drilling depth.

[0040] A clamp 720 is bolted to the top of the base 710. The clamp 720 has a horizontally positioned material hole 721 through which the conduit to be processed can be inserted. A positioning hole 722 is provided on the top of the clamp 720, communicating with the material hole 721 and positioned directly below the punching tool 310. The conduit to be processed is inserted into the material hole 721. The motor 600 drives the punching shaft 300 to rotate, while the drive shaft 400 is manually rotated to press down the punching shaft 300, thereby driving the punching tool 310 to pass through the positioning hole 722 and punch the conduit. This facilitates operation and ensures the circumferential quality of the hole structure, as well as the stability and reliability of the hole quality.

[0041] Furthermore, a worm gear 920 is fitted onto the drive shaft 400, and the worm gear 920 can rotate relative to the drive shaft 400. A worm 930 is rotatably mounted on the housing 100, and the worm 930 is meshed with the worm gear 920. One end of the worm 930 extends out of the housing 100 and is provided with an adjustment knob, so that people can grasp the adjustment knob to rotate the worm 930.

[0042] A first limiting block 900 is mounted on the outer periphery of the worm gear 920. A limiting wheel 420 is mounted on the drive shaft 400, and a second limiting block 910 is mounted on the outer periphery of the limiting wheel 420. When the drive shaft 400 rotates relative to the housing 100, it drives the second limiting block 910 to rotate. When the drive shaft 400 rotates to a preset position, the second limiting block 910 abuts against the first limiting block 900, thereby limiting the rotation angle of the drive shaft 400 and thus limiting the falling position of the drilling tool 310, thereby limiting the drilling depth. Furthermore, by rotating the worm 930, the worm gear 920 is driven to rotate, causing the circumferential position of the first limiting block 900 to change, thereby adjusting the limiting position on the drive shaft 400 and thus adjusting the drilling depth. The adjustment knob is also provided with a second scale line distributed in a circle, and the outer casing 100 is provided with a second comparison line near the scale. By comparing the second scale line with the second comparison line, the drilling depth of the drilling tool 310 can be indicated, so that the operator can control the drilling depth.

[0043] In other embodiments, the worm gear 920 and worm 930 may not be provided, and the first limiting block 900 may be installed inside the housing 100. When the drive shaft 400 is rotated and the drilling tool 310 falls, the second limiting block 910 on the drive shaft 400 abuts against the first limiting block 900 to achieve the maximum drilling depth.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
