Description

Technical Field

[0001] The invention relates to the technical field of water pump production equipment, in particular to a water pump casing drilling tool. Background Art

[0002] A water pump is a pumping machine that uses the centrifugal motion of water. It consists of a pump casing, an impeller, a pump shaft and an electric motor. The impeller is installed in the impeller cavity of the pump casing. The motor drives the impeller to rotate and at the same time drives the water in the pump casing to rotate at high speed. The water moves centrifugally, is thrown outward and is pressed into the outlet pipe. In the process of processing the water pump, it is often necessary to drill holes in its casing.

[0003] The existing Chinese patent (publication number: CN117358979A) is a synchronous drilling machine for threaded holes in water pump housings, comprising: a bed, a tool holder, a tool holder for installing tools is fixedly installed on the bed, 12 chucks are rotatably installed on the tool holder, a fixed rod is installed on the bed, the chucks are fixedly installed on the fixed rod, a rotating shaft is installed on the tool holder, the chucks are divided into 6 groups, and an adjustment unit is provided on the rotating shaft. The adjustment unit is used to control the rolling of each group of chucks on the tool holder separately, or drive the chucks to rotate. The chucks automatically fix the tools through the rotation of the tool holder. A fixing unit is provided on the bed, and the fixing unit locks the movement of the fixing rod after the adjustment unit completes the spacing adjustment of each group of chucks. The present invention can adjust the angles between the various tools on the synchronous drilling machine without disassembling the tool holder, thereby improving the processing efficiency of the synchronous machine, saving the time required for replacing calibration and tool holders, and improving experimental efficiency;

[0004] During the process of drilling holes in the water pump casing, the above-mentioned drilling device can drill holes on the water pump casing by synchronously moving multiple cutter heads. However, during the drilling process, since the multiple cutter heads are fixedly connected and synchronously adjusted, during the drilling process, it is often only possible to drill holes with the same spacing, while in the actual drilling process, it may be necessary to drill holes with different spacings. Therefore, it may be necessary to install or remove some of the cutter heads, and disassembling the drill bits takes a certain amount of time to complete. This method will undoubtedly affect the efficiency of drilling holes in the water pump. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a water pump casing drilling tool, including a workbench and a drill bit for drilling arranged on the workbench, including a hole spacing adjustment component, which is arranged above the workbench, including a rotatably connected transmission gear ring, a plurality of connecting gears meshingly connected to the transmission gear ring, and a transmission rack meshingly connected to the connecting gears to drive the drill bit to adjust the drilling spacing; a sub-control component is arranged in the hole spacing adjustment component, including a plurality of magnetic plates, the magnetic plates are connected to the connecting gears, the magnetic plates are connected to a connecting spring, and the other end of the connecting spring is connected to an electromagnet.

[0008] Furthermore, the workbench is also provided with a first positioning component, which includes an installation frame connected to the workbench, a rotating plate rotatably connected in the installation frame, a plurality of connecting plates rotatably connected on the rotating plate, a slide plate rotatably connected at the other end of the connecting plate, a first limit block connected to the slide plate, and the first limit block is slidably connected to the top of the installation frame.

[0009] Furthermore, a second limit assembly is also provided on the mounting frame, and the second limit assembly includes a mounting tube connected to the mounting frame and a mounting shaft connected to the rotating plate, a plurality of fixed plates are slidably connected in the mounting tube, a sliding block is connected to one side of the fixed plate, one end of the sliding block extends to the outside of the mounting tube and is connected to a second limit block, and a plurality of interference blocks are connected to the mounting shaft, and the positions of the interference blocks correspond to the fixed plates. As the interference blocks rotate, they can gradually interfere with the fixed plates to make the sliding block slide away from the center of the mounting shaft.

[0010] Furthermore, at least two compression springs are connected to the fixing plate, the two compression springs are symmetrical to each other, and the other ends of the compression springs are connected to the inner wall of the mounting tube.

[0011] Furthermore, a servo motor for driving the rotating plate to rotate is connected to the bottom of the workbench, a connecting shaft is connected to the driving end of the servo motor, a driven gear is provided on the connecting shaft, one side of the driven gear is meshed with a driving gear, and one side of the driving gear is meshed with a fixed frame to drive the fixed frame to rotate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. By selectively starting the sub-control component to control the meshing state of the connecting gear and the transmission rack, the spacing between multiple drill bits can be accurately adjusted, so that the user can only make some drill bits work according to actual needs, while keeping other drill bits still, to meet different drilling requirements. This setting can conveniently adjust the spacing between drill bits and realize drilling of holes with different spacings; 2. The first positioning assembly and the second limiting assembly are used in cooperation, the connecting plate is driven to rotate by the rotating plate, and then the sliding plate and the first limiting block are driven to slide, so that the first limiting block moves toward the center of the circle and fixes the outer surface of the water pump housing, and the resistance block is driven to rotate by the mounting shaft, so that the resistance block contacts the fixing plate and pushes the slider to slide outward, so that the second limiting block conflicts with the inner wall of the water pump housing, and the first positioning assembly and the second limiting assembly work together to achieve comprehensive fixation of the water pump housing. This arrangement improves the positioning stability and facilitates the synchronous driving of related components, thereby effectively fixing the water pump housing; 3.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-9 The present invention provides a technical solution: comprising a workbench 1, a drill bit 2 for drilling arranged on the workbench 1, a hole spacing adjustment component 300 for adjusting the drilling spacing, a sub-control component 400 for adjusting the number of drilling holes, a first positioning component 500 for fixing the outer side of the water pump housing, and a second limiting component 600 for fixing the inner side of the water pump housing.

[0019] In the present invention, a driving motor is connected to the drill bit 2, and the driving motor can drive the drill bit 2 to rotate to perform drilling operations, but the above-mentioned equipment is irrelevant to the technical problem to be solved by the present invention, and therefore is not drawn; Preferably, an electric telescopic rod 15 may be connected above the drill bit 2 to adjust the depth and position of the drilling; The first positioning assembly 500 and the second limiting assembly 600 can be used in conjunction to synchronously fix the outer side and the inner side of the water pump housing, thereby improving the stability of the water pump housing during drilling. The sub-control assembly 400 is convenient for adjusting the number of drill bits 2 to better meet actual needs. The hole spacing adjustment assembly 300 can be used to adjust the drilling spacing between multiple drill bits 2. In order to facilitate the adjustment of the spacing of the drilled holes, further disclosure of the structure of the hole spacing adjustment component 300 is required. Please refer to Figures 1 to 3 The hole spacing adjustment component 300 is arranged above the workbench 1, and includes a rotatably connected transmission gear ring 302, a plurality of connecting gears 303 meshingly connected to the transmission gear ring 302, and a transmission rack 304 meshingly connected to the connecting gear 303 to drive the drill bit 2 to adjust the drilling hole spacing. The hole spacing adjustment component 300 also includes a fixed frame 301 connected to the workbench 1, the transmission gear ring 302 and the connecting gear 303 are both rotatably connected in the fixed frame 301, and the plurality of connecting gears 303 are evenly spaced and distributed in a circular array with the central axis of the fixed frame 301 as the center; During specific implementation, the rotating transmission gear ring 302 can drive multiple connecting gears 303 to rotate synchronously. During the rotation process, the connecting gear 303 can drive multiple transmission racks 304 to move toward a position close to the center of the transmission gear ring 302. At this time, the drill bit 2 is adjusted synchronously with the transmission rack 304, thereby adjusting the spacing between the multiple drill bits 2 to facilitate adaptation to different drilling requirements.

[0020] In order to adjust the number of drill bits 2 according to actual needs, it is necessary to further disclose and explain the structure of the sub-control component 400. Figure 4 and Fig. 9 The sub-control component 400 is arranged in the hole spacing adjustment component 300, and includes multiple magnetic plates 401. The magnetic plate 401 is connected to the connecting gear 303. The magnetic plate 401 is connected to a connecting spring 402. The other end of the connecting spring 402 is connected to an electromagnet 403. The electromagnet 403 is rotatably connected in the fixed frame 301.

[0021] During specific implementation, the sub-control component 400 is started to generate magnetism to drive the magnetic plate 401 to move in the direction close to the electromagnet 403. The magnetic plate 401 can synchronously drive the connecting gear 303 to move during the movement. The connecting gear 303 is no longer meshed with the transmission rack 304 during the movement. When the connecting gear 303 is no longer meshed with the transmission rack 304, the drill bits 2 connected to the upper transmission rack 304 will no longer be affected by the rotation of the connecting gear 303 and the spacing will be adjusted, and the remaining unaffected drill bits 2 can adjust the spacing again. In the actual production process, assuming that eight drill bits 2 are provided and only six drill bits 2 are required to work at the same time, the electromagnets 403 on the corresponding six connecting gears 303 are closed, so that the six connecting gears 303 can drive the corresponding transmission racks 304 to move synchronously; at the same time, the corresponding electromagnets 403 on the remaining two connecting gears 303 are opened to keep the two transmission racks 304 stationary. In this way, the spacing between the multiple drill bits 2 can be adjusted as needed, thereby facilitating drilling holes with different spacings.

[0022] To prevent the pump housing from shaking during drilling, the pump housing needs to be fixed. Figures 5 to 7 The workbench 1 is also provided with a first positioning assembly 500, which includes a mounting frame 501 connected to the workbench 1, a rotating plate 502 is rotatably connected to the mounting frame 501, a plurality of connecting plates 503 are rotatably connected to the rotating plate 502, a slide plate 504 is rotatably connected to the other end of the connecting plate 503, a first limiting block 505 is connected to the slide plate 504, and the first limiting block 505 is slidably connected to the top of the mounting frame 501; During specific implementation, the rotating plate 502 can drive the connecting plate 503 to rotate. During the rotation, the connecting plate 503 can drive the sliding plate 504 to slide synchronously. As the sliding plate 504 slides, the first limit block 505 can be driven to slide synchronously toward the center of the rotating plate 502. At this time, the outer surface of the water pump housing can be fixed.

[0023] To further improve the fixing effect of the water pump housing, please refer to Figure 8 , a second limiting assembly 600 is also provided on the mounting frame 501, and the second limiting assembly 600 includes a mounting tube 602 connected to the mounting frame 501 and a mounting shaft 601 connected to the rotating plate 502, a plurality of fixed plates 603 are slidably connected in the mounting tube 602, a slider 604 is connected to one side of the fixed plate 603, one end of the slider 604 extends to the outside of the mounting tube 602 and is connected to a second limiting block 605, and a plurality of abutting blocks 606 are connected to the mounting shaft 601, and the positions of the abutting blocks 606 correspond to the fixed plates 603, and as the abutting blocks 606 rotate, they can gradually abut the fixed plates 603 to make the slider 604 slide away from the center of the mounting shaft 601; During specific implementation, the installation shaft 601 can drive the resistance block 606 to rotate synchronously. During the rotation, the resistance block 606 can gradually resist the fixed plate 603 and drive the slider 604 to slide to a position away from the center of the installation shaft 601. At this time, the second limit block 605 connected to the slider 604 can move synchronously and gradually resist the inner wall of the water pump housing, thereby cooperating with the first positioning component 500 to complete the fixation of the water pump housing. The set installation shaft 601 facilitates the synchronous movement of the components in the first positioning component 500 and the second limit component 600, thereby improving the positioning stability.

[0024] For details, please refer to Figure 8 At least two compression springs 7 are connected to the fixed plate 603, and the two compression springs 7 are symmetrical to each other. The other end of the compression spring 7 is connected to the inner wall of the mounting tube 602; the compression spring 7 is arranged to facilitate driving the slider 604 to rebound and return to the initial state when the resistance block 606 does not conflict with the fixed plate 603.

[0025] For details, please refer to Figure 6 The bottom of the workbench 1 is connected to a servo motor 11 for driving the rotating plate 502 to rotate, the driving end of the servo motor 11 is connected to a connecting shaft 10, a driven gear 9 is provided on the connecting shaft 10, one side of the driven gear 9 is meshed with a driving gear 8, and one side of the driving gear 8 is meshed with the fixed frame 301 to drive the fixed frame 301 to rotate; It should be noted that the driven gear 9 is sleeved on the connecting shaft 10, and the servo motor 11 can be selected to drive the components in the hole spacing adjustment component 300 to adjust the use position of the drill bit 2 according to the needs, or the servo motor 11 is not used to drive the components in the hole spacing adjustment component 300. Since in the actual working process, the spacing of the drill holes has no direct relationship with the diameter of the water pump housing, the servo motor 11 can be selected as the driving source of the hole spacing adjustment component 300 according to the needs in the actual production process, or other driving sources can be used; The servo motor 11 can be used as a driving source to drive the components in the first positioning assembly 500 to work, and the connecting shaft 10 can drive the driven gear 9 to rotate, so that the driven gear 9 drives the driving gear 8 and the transmission gear ring 302 to rotate synchronously; For details, please continue to refer to Figure 6 The driving end of the servo motor 11 is also connected to a first synchronous wheel 12, one end of the mounting shaft 601 extends into the workbench 1 and is connected to a second synchronous wheel 13, and a synchronous belt 14 is connected between the first synchronous wheel 12 and the second synchronous wheel 13; During specific implementation, the first synchronous wheel 12, the second synchronous wheel 13 and the synchronous belt 14 can be used in conjunction with each other to enable the first positioning assembly 500 and the second limiting assembly 600 to be positioned synchronously, thereby improving the stability of positioning.

[0026] The second limit block 605 and the first limit block 505 are both arc-shaped in design, and the outer surface of the second limit block 605 and the inner surface of the first limit block 505 are integrally formed with anti-slip patterns; this arrangement improves the stability of positioning the water pump housing.

[0027] Working principle: When drilling is required: The rotating transmission gear ring 302 can drive the multiple connecting gears 303 to rotate synchronously. The connecting gears 303 can drive the multiple transmission racks 304 to move to a position close to the center of the transmission gear ring 302 during the rotation. At this time, the drill bit 2 is adjusted synchronously with the transmission rack 304, so as to adjust the spacing between the multiple drill bits 2 and thus facilitate adaptation to different drilling requirements; The sub-control component 400 set when started can generate magnetism to drive the magnetic plate 401 to move in the direction close to the electromagnet 403. The magnetic plate 401 can synchronously drive the connecting gear 303 to move during the movement. The connecting gear 303 is no longer meshed with the transmission rack 304 during the movement. When the connecting gear 303 is no longer meshed with the transmission rack 304, the drill bits 2 connected to the upper transmission rack 304 will no longer be affected by the rotation of the connecting gear 303 and the spacing will be adjusted, and the remaining unaffected drill bits 2 can adjust the spacing again. In the actual production process, assuming that eight drill bits 2 are provided and only six drill bits 2 are required to work at the same time, the electromagnets 403 on the corresponding six connecting gears 303 are closed, so that the six connecting gears 303 can drive the corresponding transmission racks 304 to move synchronously; at the same time, the corresponding electromagnets 403 on the remaining two connecting gears 303 are opened to keep the two transmission racks 304 stationary, so that the spacing between the multiple drill bits 2 can be adjusted as needed, thereby facilitating the drilling of holes with different spacings. The rotating plate 502 is arranged to drive the connecting plate 503 to rotate, and the connecting plate 503 can drive the sliding plate 504 to slide synchronously during the rotation process. As the sliding plate 504 slides, the first limiting block 505 can be driven to slide synchronously toward the position of the center of the rotating plate 502. At this time, the outer surface of the water pump housing can be fixed, and the mounting shaft 601 can drive the resistance block 606 to rotate synchronously. The resistance block 606 can gradually resist the fixed plate 603 during the rotation process and drive the sliding block 604 to slide to a position away from the center of the mounting shaft 601. At this time, the second limiting block 605 connected to the sliding block 604 can move synchronously and gradually resist the inner wall of the water pump housing, thereby cooperating with the first positioning component 500 to complete the fixation of the water pump housing. The mounting shaft 601 is convenient for driving the components in the first positioning component 500 and the second limiting component 600 to move synchronously, thereby improving the positioning stability.
