TECHNICAL FIELD
[0001] The utility model relates to the track panel processing and manufacturing technical field, and particularly relates to a threaded hole processing device. BACKGROUND
[0002] In the rail transit industry in China, the medium and low speed maglev technology is not only environmental protection, high safety, but also has many advantages such as strong climbing ability, small turning radius, low construction cost, etc., so in the new rail transit construction planning of all places, the medium and low speed maglev technology has become the preferred scheme. The track panel of medium and low speed maglev is composed of steel rails with F-shaped cross section, and each rail needs to be radially configured with bolt mounting holes for grounding wires at both ends. In the manufacturing of medium and low speed maglev track panel, the processing quality of bolt mounting holes directly determines the safety of line maintenance personnel and trackside equipment.
[0003] For the processing of maglev track panel threaded holes, the traditional way is manual operation, that is, first use a hand drill with a drill jig to drill a bottom hole of the threaded hole, then remove the drill jig and use a hand tapping or tapping machine to tap threads. However, the left and right tracks of medium and low speed maglev and the forms and specifications of track joints are various, and there are tens of thousands of tracks on a maglev line, which requires processing of hundreds of thousands of threaded holes. Therefore, in the processing of maglev track panel threaded holes, on the one hand, this traditional processing method is manually operated by workers, which has the problems of high labor intensity and low work efficiency, and cannot meet the needs of mass production of threaded holes. At the same time, when drilling with a hand drill, the torque of the hand drill is too large, making it difficult for workers to keep the hand drill stable, resulting in that the diameter and perpendicularity of the processed threaded holes cannot be guaranteed, the processing quality is poor, and the drill bit is easily broken and the hole is damaged, increasing the difficulty of cost control. On the other hand, this traditional processing method uses a drilling and tapping separation process, and the production mode of frequent disassembly and assembly of drill jig and manual tapping will result in slow processing speed and low efficiency of threaded holes, which cannot meet the quality and efficiency of maglev track panel assembly.

DETAILED DESCRIPTION
[0035] The embodiments of the utility model are explained in detail below in combination with the drawings, but the utility model can be implemented in various different ways limited and covered by the following.
[0036] As shown in Figure 1 , Figure 2 and Figure 3 , the magnetic levitation track row is composed of steel rails with F-shaped cross section, and the two ends of each rail need to be radially configured with bolt mounting holes for ground wire use, the threaded hole processing device of the embodiment is used for processing the ground wire hole, and is especially suitable for the ground wire hole on the medium-low speed magnetic levitation track row. Specifically, the threaded hole processing device comprises a main frame 200, a drilling machine mechanism 300 and a drill sleeve mechanism 400, the main frame 200 can adapt to the left and right rails of the magnetic levitation track row and different rail joint forms, so that the positioning connection with the workpiece 100 to be processed can be realized through the main frame 200, the stability in the threaded hole processing process is ensured, and at the same time, the main frame 200 can reserve the machining position of the pre-machining threaded hole position of the workpiece 100 to be processed, so as to realize the accurate and rapid positioning of the hole position to be processed, and ensure the processing precision and speed.
[0037] The drilling machine mechanism 300 is installed on the main frame 200 and is used for drilling and tapping the pre-machining threaded hole position on the workpiece 100 to be processed to form a threaded hole. The drilling machine mechanism 300 can realize drilling and tapping, so that a set of the device can realize the machining of the radial threaded hole of the magnetic levitation track, which is simple, convenient and high in working efficiency. Preferably, in the embodiment, the drilling machine mechanism 300 is detachably installed on the main frame 200 through magnetic attraction and can slide on the main frame 200 in the height direction to adjust the height position of the drilling machine mechanism 300, so that the drilling machine mechanism 300 can be adjusted in the height direction to correspond to the axial direction of the pre-machining threaded hole position, improve the flexibility and on-site adaptability of the device, and enhance the practicability. Alternatively, the drilling machine mechanism 300 can also be movably connected with the main frame 200. Alternatively, the drilling machine mechanism 300 can also be fixed on the main frame 200 at a position corresponding to the pre-machining threaded hole position, so as to avoid repeated adjustment and save processing time.
[0038] The drill bushing mechanism 400 is movably mounted on the main frame 200 and arranged radially along the hole to be machined. Preferably, in this embodiment, the drill bushing mechanism 400 is slidably mounted on the main frame 200 in the horizontal direction. Thus, through the movable cooperation between the drill bushing mechanism 400 and the main frame 200, when the drilling mechanism 300 performs drilling operations, the drill bushing mechanism 400 can be slid to the axially corresponding position of the pre-machined threaded hole to guide the drilling, ensuring the coaxiality of the drilling mechanism 300 and the hole to be machined, preventing the drilling mechanism 300 from shifting during drilling, avoiding damage to the drilling mechanism 300 or the hole to be machined, improving drilling accuracy, and ensuring the processing quality of the threaded hole. Furthermore, when the drilling mechanism 300 performs tapping operations, the drill jig mechanism can be slid away to the position of the preset threaded hole to avoid affecting the tapping operation of the drilling mechanism 300. Compared with the prior art, switching between drilling and tapping does not require disassembling the drill jig mechanism, greatly reducing labor intensity, improving work efficiency, and meeting the needs of processing large batches of threaded holes.
[0039] like Figure 1 , Figure 2 and Figure 4As shown, the main frame 200 includes a flat plate 201, a vertical plate 202 perpendicular to the flat plate 201 and fixed to the end of the flat plate 201, a reinforcing plate 203 installed at the corner connection between the flat plate 201 and the vertical plate 202, and a positioning clamping member connected to the flat plate 201. The positioning clamping member is used to pass through the workpiece to be processed and position and clamp the workpiece to be processed onto the flat plate. Specifically, the positioning clamping member passes through the flat plate 201 and the workpiece to be processed 100 in sequence to position and lock the workpiece to be processed 100 and the flat plate 201. The reinforcing plate 203 is fixedly connected to both the flat plate 201 and the vertical plate 202 to enhance the structural strength of the main frame 200 and improve its load-bearing capacity. The drilling mechanism 300 and the drill sleeve mechanism 400 are both installed on the side of the vertical plate 202 away from the flat plate 201. Therefore, the positioning connection between the main frame 200 and the workpiece 100 ensures the stability of the drilling mechanism 300 and the drill sleeve mechanism 400, making the threaded hole machining process stable, reliable, and highly safe. Furthermore, it allows for the positioning of the drilling mechanism 300 and the drill sleeve mechanism 400, ensuring precise alignment with the pre-machined threaded hole positions and guaranteeing machining quality. The main frame 200 also includes a drilling positioning plate 204, which is positioned below the drilling mechanism 300 and slidably mounted on the vertical plate 202 along the height direction. This positioning plate is used to position the drilling mechanism 300 so that it axially aligns with the pre-machined threaded hole positions on the workpiece 100. Specifically, the drilling positioning plate 204 has oblong holes arranged along the height direction. Bolts are passed sequentially through the oblong holes and the vertical plate 202 to mount the drilling positioning plate 204 on the vertical plate 202, allowing for vertical adjustment of the drilling positioning plate 204 on the vertical plate 202. Optionally, the oblong hole can be replaced with a sliding groove. Optionally, the drilling rig positioning plate 204 can be directly fixed to the main frame 200; optionally, the drilling rig positioning plate 204 can be directly connected to the drilling mechanism 300.
[0040] like Figure 2 and Figure 4As shown, the positioning and clamping component includes a positioning pin 2014 and a clamping bolt 2013. The plate 201 has a positioning hole 2011 and a fastening groove 2012. The positioning hole 2011 and the fastening groove 2012 are both corresponding to the workpiece 100 to be processed. In use, the positioning pin 2014 is sequentially inserted into the positioning hole 2014 of the workpiece 100 to be processed and the plate 201 to be processed for positioning. The clamping bolt 2013 is placed in the fastening groove 2012 and locked with a nut on the end face of the workpiece 100 and / or the plate 201. Thus, through the cooperation of the positioning pin 2014 with the positioning hole 2011 and the cooperation of the clamping bolt 2013 with the fastening groove 2012, the main frame 200 and the workpiece 100 to be processed are positioned and clamped. Specifically, the positioning holes 2011 are symmetrically arranged on both sides of the fastening groove 2012, and both the positioning holes 2011 and the fastening groove 2012 are symmetrically arranged along the maglev track to adapt to the left and right tracks of the maglev track and different track joint types. This allows the flat plate 201 to be positioned and connected to any left or right track of the maglev track through the positioning holes 2011 and the fastening groove 2012. In use, one positioning hole 2011 and one fastening groove 2012 are selected according to the different joint types and drilling positions of the track. The clamping bolts 2013 are then passed through the positioning hole 2011 and the corresponding drilled hole on the track in sequence, and then through the fastening groove 2012 and the corresponding groove on the track in sequence, to lock the main frame 200 to the track. The connection speed is fast and the applicability is wide.
[0041] like Figure 4As shown, a first mounting groove 2021 and a second mounting groove 2022 are provided on the side of the upright plate 202 away from the flat plate 201. The first mounting groove 2021 and the second mounting groove 2022 are arranged sequentially along the height direction. The first mounting groove 2021 is located above the second mounting groove 2022. The drilling mechanism 300 and the drilling positioning plate 204 are installed in the first mounting groove 2021, and the drilling positioning plate 204 is located below the drilling mechanism 300. Thus, the drilling mechanism 300 can be limited on both sides through the first mounting groove 2021. The first mounting groove 2021 guides the vertical movement of the drilling mechanism 300, preventing misalignment during position adjustment and avoiding excessive time required for positioning with pre-machined threaded holes. In this embodiment, the drilling mechanism 300 is magnetically attached to the first mounting groove 2021 of the vertical plate 202. The opening of the first mounting groove 2021 faces upward, allowing the drilling mechanism 300 to slide out through it, facilitating installation and removal, high flexibility, and easy reuse. The drilling positioning plate 204 is installed in the first mounting groove 2021 of the vertical plate 202 through the engagement of a slotted hole and bolts to limit the lower section of the drilling mechanism 300, thus achieving vertical positioning of the drilling mechanism 300. The second mounting groove 2022 is horizontally oriented with its opening facing the side of the vertical plate 202. The drill sleeve mechanism 400 is slidably mounted horizontally within the second mounting groove 2022. Preferably, the second mounting groove 2022 is a T-slot, allowing the vertical plate 202 and the drill sleeve mechanism 400 to engage and cooperate through the T-slot. The second mounting groove 2022 guides and limits the drill sleeve mechanism 400, preventing it from dislodging from the vertical plate 202. When the drilling mechanism 300 has been positioned and drilling of the pre-machined threaded hole is required, the drill sleeve mechanism 400 is moved horizontally to a position corresponding to the axial direction of the pre-machined threaded hole to guide the drilling of the drilling mechanism 300, preventing drilling deviation and improving drilling quality and machining accuracy. When the drilling mechanism 300 needs to tap the pre-machined threaded hole, the drill sleeve mechanism 400 is moved horizontally out of the pre-machined threaded hole to avoid interference with tapping of larger diameter taps. Therefore, switching between drilling and tapping does not require removing the drill bushing mechanism 400, greatly improving processing efficiency.
[0042] like Figure 4As shown, the vertical plate 202 is also provided with a drill sleeve positioning hole 2023 in the second mounting groove 2022. The drill sleeve positioning hole 2023 is set to correspond to the pre-processed threaded hole of the workpiece 100, so that the drill sleeve mechanism 400 can be axially inserted to position the drill sleeve mechanism 400 at a position corresponding to the axial position of the pre-processed threaded hole of the workpiece 100. Specifically, the diameter of the drill bushing mechanism 400 is matched with the diameter of the hole to be machined to guide the drilling operation and ensure drilling accuracy. The diameter of the drill bushing positioning hole 2023 is larger than the diameter of the hole to be machined. Therefore, before the drilling machine mechanism 300 performs drilling operations on the preset threaded hole, the drill bushing mechanism 400 is moved to the pre-machined threaded hole position, aligning it with the axes of the hole to be machined and the drill bushing positioning hole 2023. Then, the drill bushing mechanism 400 is inserted into the drill bushing positioning hole 2023 and reaches the end face of the workpiece 100 to form a guide channel, achieving precise guidance for the drilling operation of the drilling machine mechanism 300. Since the diameter of the tap is larger than the diameter of the hole to be machined, the diameter of the drill bushing positioning hole 2023 must be larger than the diameter of the tap used for tapping, to prevent the drilling machine mechanism 300 from having difficulty entering the drilled hole for tapping during the tapping operation, ensuring smooth tapping.
[0043] like Figure 6 As shown, a slot 2024 is provided on the side of the upright plate 202 near the flat plate 201. The slot 2024 is arranged horizontally on the side of the flat plate 201 away from the reinforcing plate 203, and is used to engage with the side end of the workpiece 100. Thus, the engagement of the slot 2024 of the upright plate 202 with the workpiece 100 enhances the stability of the connection between the main frame 200 and the workpiece 100, ensuring a stable and reliable structure and preventing shaking during the machining of threaded holes. Simultaneously, it improves the accuracy and speed of positioning the main frame 200 and the workpiece 100, allowing the main frame 200 to be quickly and accurately positioned at the machining position of the workpiece 100, resulting in high efficiency.
[0044] Preferably, a chip removal groove is provided at the location of the drill bushing positioning hole 2023. The chip removal groove is opened on the side of the vertical plate 202 near the flat plate 201, and is arranged in the slot 2024 of the vertical plate 202 and communicates with the drill bushing positioning hole 2023 to collect the waste chips generated during the machining of the threaded hole. After the vertical plate 202 is engaged with the side end of the workpiece 100 through the slot 2024, the chip removal groove is covered on the side end of the workpiece 100. Thus, during the machining of the threaded hole, the chip removal groove can effectively prevent the waste chips at the location of the drill bushing positioning hole 2023 from splashing into the external environment, avoiding environmental pollution, and at the same time preventing the waste chips from splashing and causing injury to personnel, thereby improving the safety of the device.
[0045] like Figure 1 and Figure 5As shown, the drilling mechanism 300 includes a base 301, a frame 302 fixed on the base 301, and a power assembly 303 and a control assembly 304 mounted on the frame 302. The base 301 is slidably mounted in the first mounting groove 2021 along the height direction, so as to adjust the power assembly 303 to a height corresponding to the axial direction of the pre-machined threaded hole position of the workpiece 100. Preferably, the base 301 is a magnetic base 301 with an internal electromagnetic coil, which is attracted to the upright plate 202 of the main frame 200 by electromagnetic force, which facilitates the position adjustment of the drilling mechanism 300, is easy to install and disassemble, has high flexibility, and can be reused. Optionally, the base 301 and the main frame 200 can also be movably snapped together or fixedly connected.
[0046] The power assembly 303 is slidably mounted on the frame 302 in a horizontal direction for drilling and tapping pre-machined threaded holes. The control assembly 304 is engaged with the power assembly 303 to control the movement of the power assembly 303 toward and / or away from the pre-machined threaded hole. The control assembly 304 can adjust the horizontal position of the power assembly 303 and control the retraction of its output end. Specifically, when a drill bit is mounted on the power assembly 303 for drilling, the control mechanism moves the power assembly 303 horizontally on the frame 302, moving the entire power assembly 303 to the pre-machined threaded hole and aligning the drill bit with it. The power assembly 303 is then activated to begin drilling. After drilling, the drill bit is replaced with a tap and mounted on the power assembly 303. The power assembly 303 is then activated for tapping. After forward tapping is completed, the control assembly 304 retracts the tap to complete reverse tapping.
[0047] like Figure 5 As shown, the power assembly 303 includes a connecting block 3031 for sliding connection with the frame 302, a clamping member 3032 for holding a drill bit or tap, and a drive motor 3033 for providing power for the rotation and axial movement of the drill bit or tap. The drive motor 3033 is fixed to the connecting block 3031, and the clamping member 3032 is fixed to the output end of the drive motor 3033. Therefore, turning on the drive motor 3033 controls the drill bit for drilling and the tap for tapping. Drilling and tapping can be performed by simply replacing the drill bit or tap on the clamping member 3032, effectively improving work efficiency.
[0048] The power assembly 303 also includes an ultrasonic power component 3034 for assisting the drill bit in drilling. The ultrasonic power component 3034 includes an ultrasonic power supply electrically connected to the drive motor 3033 and a transducer mounted on the drive motor 3033. The ultrasonic power supply and the power supply of the drive motor 3033 are integrated inside the frame 302. The transducer is connected to the output end of the drive motor 3033 to convert the electrical energy of the ultrasonic power supply into ultrasonic energy. The high-frequency vibration of the ultrasonic waves can give the drill bit on the clamping member 3032 a very large impact acceleration, thereby greatly enhancing the drilling efficiency. Compared with the drilling method of direct cutting in the prior art, this device can significantly reduce the cutting force of drilling through the ultrasonic power component 3034, effectively improving the drilling quality. Specifically, a drill bit is installed on the clamping member 3032. When the drive motor 3033 is turned on to drill, the ultrasonic power unit 3034 is activated. The ultrasonic power unit 3034 converts electrical energy into ultrasonic energy through a transducer and acts on the drill bit to perform efficient and high-quality drilling. After drilling is completed, the ultrasonic power unit 3034 is turned off so that the power unit 303 can perform tapping operations subsequently.
[0049] like Figure 5 As shown, the control assembly 304 includes a handle wheel 3041 for controlling the movement of the drive motor 3033 relative to the frame 302, and a control button 3042 for controlling the movement of the clamping member 3032 relative to the drive motor 3033. The handle wheel 3041 is engaged with the connecting block 3031 and mounted on the frame 302. The control button 3042 is electrically connected to the drive motor 3033 and mounted on the handle wheel 3041. Specifically, a slot is provided on the frame 302. The connecting block 3031 slides through the slot and is engaged with the handle wheel 3041 within the frame 302. The handle wheel 3041 is mounted on the outside of the frame 302. By rotating the handle wheel 3041, the connecting block 3031 can be controlled to move the drive motor 3033 horizontally toward or away from the pre-machined threaded hole. The control button 3042 is installed at the end of the handle wheel 3041. When the power assembly 303 has completed the forward tapping, pressing the control button 3042 will reverse the drive motor 3033 and cause the tap to retract.
[0050] like Figure 6 and Figure 7As shown, the drill bushing mechanism 400 includes a slider 401 and a drill bushing 402. The slider 401 is movably engaged in the second mounting groove 2022 in the horizontal direction. The drill bushing 402 is installed in the slider 401 to axially guide the drill bit or tap. Specifically, the inner diameter of the drill bushing 402 is adapted to the diameter of the hole to be machined. The slider 401 has a mounting hole for mounting the drill bushing 402. The drill bushing 402 includes a threaded section 4021 and a smooth section 4022. The drill bushing 402 passes through the mounting hole of the slider 401 and is threadedly connected to the mounting hole through the threaded section 4021. Preferably, the length of the drill bushing 402 is greater than the length of the mounting hole, so that the smooth section 4022 of the drill bushing 402 can extend from the mounting hole into the drill bushing positioning hole 2023 for positioning, and the smooth section 4022 of the drill bushing 402 can extend to the end face of the workpiece 100 to accurately guide the drilling operation and improve the quality of the threaded hole machining. Preferably, a groove is provided on the end face of the threaded section 4021 of the drill bushing 402 away from the smooth section 4022, so as to facilitate screwing with the equipment.
[0051] like Figure 6 As shown, the drill sleeve mechanism 400 also includes a pull rod 403 and a limiting block 404. The limiting block 404 is arranged at the opening of the second mounting groove 2022 of the vertical plate 202 and fixed to the side end of the vertical plate 202 to limit the slider 401 in the second mounting groove 2022 and prevent it from coming out of the second mounting groove 2022. One end of the pull rod 403 is fixed to the slider 401, and the other end extends out of the limiting block 404 and is movably engaged with the limiting block 404, so that the slider 401 can be pulled to slide in the second mounting groove 2022 by the pull rod 403. In use, when the drilling mechanism 300 needs to drill, push the pull rod 403 to move the slider 401 to the position corresponding to the pre-machined threaded hole. Then, screw the threaded section 4021 of the drill sleeve 402 so that the smooth section 4022 of the drill sleeve 402 extends into the drill sleeve positioning hole 2023 on the vertical plate 202 and extends to the end face of the workpiece 100 to form a guide channel for the drill bit, thereby enabling the drilling mechanism 300 to perform drilling operations. When the drilling mechanism 300 has completed drilling and needs to be replaced with a tap for tapping operations, screw the drill sleeve 402 so that the smooth section 4022 of the drill sleeve 402 disengages from the drill sleeve positioning hole 2023 on the vertical plate 202. Pull the pull rod 403 to move the slider 401 to the outside of the drill sleeve positioning hole 2023, thereby enabling the drilling mechanism 300 to perform tapping operations.
