Description

Technical Field

[0001] This invention belongs to the technical field of broaching equipment, and particularly relates to a broaching equipment for the end connecting groove of a metal compensator. Background Technology

[0002] Metal compensators, as important connecting components in pipeline systems used to compensate for axial displacement, absorb vibration, and adapt to thermal expansion and contraction, usually require further machining at their ends according to actual connection and assembly needs. One method is to use a horizontal broaching machine to drive a broach along the inner hole of the end of the metal compensator to perform linear broaching, forming a connecting groove with a certain depth and width on the inner wall of the end, so as to meet the needs of subsequent connection, positioning, and assembly. During the broaching process, the broach gradually removes metal material by relying on the continuously set cutting parts, which can stably complete the forming of the connecting groove. Therefore, it is suitable for machining the connecting groove at the end of metal compensators.

[0003] However, after existing horizontal broaching equipment completes the broaching of the connecting groove at the end of the metal compensator, there may still be certain machining marks, burrs, and local unevenness on the groove wall and groove opening. Therefore, it is usually necessary to further finish the broached connecting groove. In the current processing method, when performing subsequent finishing, it is usually necessary to transfer the broached workpiece to other processing stations, or stop the equipment, disassemble and replace the corresponding finishing tool, and then readjust the position between the tool and the machined connecting groove. This not only increases the operation steps of workpiece transfer, tool disassembly and repositioning, but also easily causes positional deviation between the finishing tool and the original connecting groove during the readjustment process. This is not conducive to maintaining the positional consistency between broaching and subsequent finishing processing, and also affects the efficiency of continuous processing of the connecting groove at the end of the metal compensator.

[0004] Based on this, the present invention designs a metal compensator end connecting groove broaching processing equipment to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the problem that existing machining methods typically require transferring the broached workpiece to other machining stations or stopping the equipment to disassemble and replace the corresponding finishing tool, and then readjusting the position between the tool and the machined connecting groove. This not only increases the number of steps involved in workpiece transfer, tool disassembly and repositioning, but also easily causes positional deviations between the finishing tool and the original connecting groove during the readjustment process. Therefore, this invention proposes a broaching machining device for the connecting groove at the end of a metal compensator.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A broaching machine for the connecting groove at the end of a metal compensator includes a horizontal machining table and a broach body. A broaching drive mechanism and a broaching moving mechanism are mounted above the horizontal machining table. A switching device is installed at the output end of the broaching moving mechanism. A tool holder is mounted on one side of the switching device, and the broach body is installed inside the tool holder. The switching device is used to rotate the tool holder and the broach body, switching the finishing tool to the machining position, thereby finishing the connecting groove formed by broaching at the end of the metal compensator. A cleaning device is installed below the switching device to clean the debris adhering to the surface of the broach body after machining. A scraping device is installed outside the cleaning device to scrape the cleaned debris to a designated position. A fixing device is installed on one side of the horizontal machining table to clamp the metal compensator and allow the metal compensator to rotate to a designated angle without being removed when machining multiple connecting grooves.

[0008] As a further description of the above technical solution:

[0009] The switching device includes a support plate, which is fixedly connected to the lower part of the broaching moving mechanism. An electric telescopic rod is installed above the support plate. A toothed plate is installed at the output end of the electric telescopic rod. A gear is meshed on the toothed plate. The gear is fixedly sleeved on the outside of the rotating rod. The rotating rod is rotatably connected to one side of the broaching moving mechanism. One end of the rotating rod is fixedly connected to one side of the tool holder.

[0010] As a further description of the above technical solution:

[0011] The switching device also includes a horizontal plate, a limit switch, a roller, a finishing cutter, and an extrusion block. The horizontal plate is fixedly connected inside the horizontal machining table. A limit switch is installed on the horizontal plate. The trigger end of the limit switch is rotatably connected to the roller. The finishing cutter is fixedly connected to the lower surface of the broach body. An extrusion block is installed below the finishing cutter. The position of the extrusion block corresponds to that of the roller.

[0012] As a further description of the above technical solution:

[0013] The switching device also includes two through-beam photoelectric sensors, which are symmetrically installed on the inner walls of both sides of the horizontal machining table. The detection ends of the two through-beam photoelectric sensors are arranged opposite each other to form a detection area. The moving path of the broach body passes through the detection area between the two through-beam photoelectric sensors.

[0014] As a further description of the above technical solution:

[0015] The cleaning device includes a push rod, a rack, and a drive rod. The push rod is fixedly connected to the bottom of the support plate. A rack is installed on one side of the push rod. The drive rod is rotatably connected to the horizontal machining table through a bearing. The outer surface of the drive rod has a toothed groove that matches the rack. The rack meshes with the toothed groove on the outer surface of the drive rod.

[0016] As a further description of the above technical solution:

[0017] A circular plate is installed above the drive rod, and two sliding rods are slidably connected inside the circular plate. The same mounting plate is installed above the two sliding rods, and a compression spring is sleeved on the outside of each of the two sliding rods. One end of the compression spring is fixedly connected to the bottom of the mounting plate, and the other end of the compression spring is fixedly connected to the top of the circular plate. A cleaning brush is installed on the top of the mounting plate by bolts.

[0018] As a further description of the above technical solution:

[0019] The scraping device includes a scraper, an arc-shaped plate, and a discharge chute. The scraper is fixedly sleeved on the outside of the drive rod, the arc-shaped plate is fixedly connected inside the horizontal processing table, the scraper is positioned above the arc-shaped plate, and the discharge chute is located on one side of the horizontal processing table. One end of the arc-shaped plate corresponds to the position of the discharge chute.

[0020] As a further description of the above technical solution:

[0021] The fixing device includes a three-jaw chuck, an adjusting plate, and a mounting shell. The adjusting plate is fixedly connected to one side of the three-jaw chuck, and the adjusting plate is rotatably connected to one side of the mounting shell. The mounting shell is fixedly connected to one side of the horizontal machining table.

[0022] As a further description of the above technical solution:

[0023] The outer surface of the mounting shell is provided with scale lines, and an arc-shaped groove is provided inside the mounting shell. Two clamping plates are symmetrically rotatably connected to one side of the adjusting plate. One end of each clamping plate is slidably connected in the arc-shaped groove. A handle is installed on one side of each clamping plate. The clamping plate is cam-shaped. Rotating the handle drives the clamping plate to rotate relative to the adjusting plate, so that the clamping plate abuts against the inner wall of the arc-shaped groove, thereby fixing the rotation angle of the adjusting plate relative to the mounting shell.

[0024] As a further description of the above technical solution:

[0025] A receiving box is installed on one side of the horizontal machining table, and a control cabinet is installed on the front of the horizontal machining table. The electric telescopic rod, limit switch and two through-beam photoelectric sensors are all electrically connected to the control cabinet.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In this invention, by setting a switching device, after the broach body completes the broaching of the connecting groove and retracts, the extrusion block triggers the limit switch, causing the control cabinet to start the electric telescopic rod. The electric telescopic rod drives the tool holder and the broach body to rotate 180 degrees through the toothed plate, gear and rotating rod, so that the finishing tool is switched to the processing position to perform finishing processing on the already formed connecting groove, thereby reducing the manual operation of changing tools and repositioning, and improving the continuity of broaching and finishing processing.

[0028] 2. In this invention, by setting up a cleaning device, when the broach body continues to move after flipping, the push rod drives the rack to move, and the rack drives the drive rod to rotate through the tooth groove, so that the cleaning brush rotates synchronously and cleans the debris on the surface of the broach body. At the same time, the compression spring keeps the cleaning brush in contact with the broach body, reducing the impact of debris residue on subsequent processing.

[0029] 3. In this invention, by setting up a scraping device, the scraper is driven to rotate at the same time as the cleaning brush is driven by the drive rod. The scraper scrapes the debris along the arc plate and discharges it into the receiving box through the discharge chute, thereby reducing the accumulation of debris inside the horizontal processing table and facilitating the centralized collection and processing of debris.

[0030] 4. In this invention, by setting a fixing device, after completing the processing of a connecting groove, the worker can release the fixing between the clamping plate and the arc groove by using the handle, then rotate the three-jaw chuck to drive the workpiece to rotate, and determine the next processing angle by the scale line, and then use the clamping plate to fix it again. Thus, the angle adjustment between multiple connecting grooves can be completed without removing the workpiece, reducing the operation of repeated clamping and realigning.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figures 1-8This invention provides a technical solution: a broaching processing device for the connecting groove at the end of a metal compensator, comprising a horizontal processing table 1 and a broach body 4. A broaching drive mechanism 2 and a broaching moving mechanism 3 are installed above the horizontal processing table 1. A switching device 5 is installed at the output end of the broaching moving mechanism 3. A tool holder 6 is installed on one side of the switching device 5. The broach body 4 is installed inside the tool holder 6. The switching device 5 is used to drive the tool holder 6 and the broach body 4 to rotate, so that the finishing tool 509 is switched to the processing position, thereby performing finishing processing on the connecting groove formed by broaching at the end of the metal compensator. A cleaning device 7 is installed below the switching device 5 to clean the debris attached to the surface of the broach body 4 after processing. A scraping device 8 is installed outside the cleaning device 7 to scrape the cleaned debris to a designated position. A fixing device 9 is installed on one side of the horizontal processing table 1 to clamp the metal compensator and to rotate the metal compensator to a designated angle without removing it when multiple connecting grooves need to be processed.

[0043] Specifically, such as Figures 2-5 As shown, the switching device 5 includes a support plate 501, which is fixedly connected to the lower part of the broaching moving mechanism 3. An electric telescopic rod 502 is installed above the support plate 501. A toothed plate 503 is installed at the output end of the electric telescopic rod 502. A gear 504 is externally meshed with the toothed plate 503. The gear 504 is fixedly sleeved on the outside of the rotating rod 505. The rotating rod 505 is rotatably connected to one side of the broaching moving mechanism 3. One end of the rotating rod 505 is fixedly connected to one side of the tool holder 6. The switching device 5 also includes a horizontal plate 506, a limit switch 507, a roller 508, a finishing tool 509, and an extrusion block 510. The horizontal plate 506 is fixedly connected to the horizontal machining center. Inside the workbench 1, a limit switch 507 is installed on the horizontal plate 506. The trigger end of the limit switch 507 is rotatably connected to a roller 508. The finishing cutter 509 is fixedly connected to the lower surface of the broach body 4. A pressing block 510 is installed below the finishing cutter 509. The pressing block 510 is positioned corresponding to the roller 508. The switching device 5 also includes two through-beam photoelectric sensors 511. The two through-beam photoelectric sensors 511 are symmetrically installed on the inner walls of both sides of the horizontal machining table 1. The detection ends of the two through-beam photoelectric sensors 511 are set opposite each other and form a detection area. The moving path of the broach body 4 passes through the detection area between the two through-beam photoelectric sensors 511.

[0044] It should be noted that, through the cooperation between the toothed plate 503 and the gear 504, when the toothed plate 503 moves linearly, it can drive the gear 504 to rotate through the meshing action between the toothed plate 503 and the gear 504, thereby converting the linear motion of the toothed plate 503 into the rotational motion of the gear 504. By controlling the travel of the toothed plate 503, the gear 504 can be rotated to a specified angle, providing a transmission basis for the 180-degree rotation of the tool holder 6.

[0045] With the cooperation of the pressing block 510 and the roller 508, when the broach body 4 completes the broaching and gradually retracts to the designated position, the pressing block 510 can move synchronously with the finishing tool 509 and gradually contact the roller 508. The pressing block 510 applies a pressing force to the roller 508, causing the roller 508 to roll during the contact process, thereby reducing the direct sliding friction between the pressing block 510 and the trigger position, and achieving stable triggering of the limit switch 507.

[0046] With the cooperation of the through-beam photoelectric sensor 511 and the broach body 4, the broach body 4 can block the detection light path when it is located between the two through-beam photoelectric sensors 511. After the broach body 4 completes the finishing process and retracts away from the detection area, the light path between the two through-beam photoelectric sensors 511 is reconnected, thereby detecting the exit state of the broach body 4, which facilitates the control of the tool holder 6 to reverse and return to the next broaching process state.

[0047] Specifically, such as Figures 6-7 As shown, the cleaning device 7 includes a push rod 701, a rack 702, and a drive rod 703. The push rod 701 is fixedly connected to the bottom of the support plate 501. The rack 702 is installed on one side of the push rod 701. The drive rod 703 is rotatably connected to the horizontal processing table 1 through a bearing. The outer surface of the drive rod 703 has a toothed groove that matches the rack 702. The rack 702 meshes with the toothed groove on the outer surface of the drive rod 703. A circular plate 704 is installed above the drive rod 703. Two slide rods 705 are slidably connected inside the circular plate 704. The same mounting plate 707 is installed above the two slide rods 705. A compression spring 706 is sleeved on the outside of each of the two slide rods 705. One end of the compression spring 706 is fixedly connected to the bottom of the mounting plate 707, and the other end of the compression spring 706 is fixedly connected to the top of the circular plate 704. A cleaning brush 708 is installed on the top of the mounting plate 707 by bolts.

[0048] It should be noted that, through the cooperation of push rod 701 and rack 702, when support plate 501 moves with broaching moving mechanism 3, it can synchronously drive push rod 701 to move. Push rod 701 further drives rack 702 to produce linear displacement, thereby using the original moving process of broaching moving mechanism 3 to provide power to the rotation of cleaning brush 708, so that the moving process of the tool can be used to drive the operation of cleaning structure at the same time.

[0049] Through the cooperation of the slide rod 705 and the compression spring 706, when the cleaning brush 708 is squeezed by the broach body 4 and drives the mounting plate 707 to move downward, the slide rod 705 slides along the circular plate 704 and compresses the compression spring 706. The compression spring 706 continuously pushes the mounting plate 707 toward the broach body 4 through its own elastic force, so that the cleaning brush 708 can maintain an elastic fit with the surface of the broach body 4, reducing the possibility of the cleaning brush 708 detaching from the broach body 4 due to slight deviations in processing dimensions and installation position.

[0050] Specifically, such as Figure 7 As shown, the scraping device 8 includes a scraper 801, an arc plate 802, and a discharge trough 803. The scraper 801 is fixedly sleeved on the outside of the drive rod 703. The arc plate 802 is fixedly connected inside the horizontal processing table 1. The scraper 801 is located above the arc plate 802. The discharge trough 803 is opened on one side of the horizontal processing table 1. One end of the arc plate 802 corresponds to the position of the discharge trough 803.

[0051] It should be noted that, through the cooperation of scraper 801 and arc plate 802, the debris cleaned by cleaning brush 708 can fall onto arc plate 802. When scraper 801 rotates with drive rod 703, it pushes the debris along the surface of arc plate 802, while arc plate 802 can restrict the movement direction of debris, so that the scattered debris gradually moves in the same direction.

[0052] Specifically, such as Figure 8 As shown, the fixing device 9 includes a three-jaw chuck 901, an adjusting plate 902, and a mounting shell 903. The adjusting plate 902 is fixedly connected to one side of the three-jaw chuck 901, and the adjusting plate 902 is rotatably connected to one side of the mounting shell 903. The mounting shell 903 is fixedly connected to one side of the horizontal machining table 1. The outer surface of the mounting shell 903 is provided with scale lines 904, and an arc-shaped groove 905 is opened inside the mounting shell 903. Two clamping plates 906 are symmetrically rotatably connected to one side of the adjusting plate 902, and one end of each clamping plate 906 is slidably connected in the arc-shaped groove 905. Each of the two clamping plates 906 has a handle 907 installed on one side. The clamping plates 906 are cam-shaped. Rotating the handle 907 causes the clamping plates 906 to rotate relative to the adjusting plate 902, so that the clamping plates 906 press against the inner wall of the arc groove 905, thereby fixing the rotation angle of the adjusting plate 902 relative to the mounting shell 903. A receiving box 10 is installed on one side of the horizontal processing table 1, and a control cabinet 11 is installed on the front of the horizontal processing table 1. The electric telescopic rod 502, the limit switch 507, and the two photoelectric sensors 511 are all electrically connected to the control cabinet 11.

[0053] It should be noted that, through the cooperation of the clamping plate 906 and the arc groove 905, when the adjusting plate 902 rotates, it can drive the clamping plate 906 to move along the arc groove 905 inside the mounting shell 903, so that the arc groove 905 restricts the movement trajectory of the clamping plate 906; when the clamping plate 906 rotates to abut against the inner wall of the arc groove 905, the abutting action between the two can be used to restrict the adjusting plate 902 from continuing to rotate, thereby fixing the adjusted angle of the three-jaw chuck 901;

[0054] With the cooperation of handle 907 and clamping plate 906, when the operator turns handle 907, the cam-shaped clamping plate 906 can be directly driven to rotate relative to the adjusting plate 902, so that the clamping plate 906 can be in a clamping state or a clamping state in the arc groove 905. This makes it easy for the operator to release the fixation before the workpiece angle is adjusted and to re-fix it after the angle adjustment is completed.

[0055] With the cooperation of the scale line 904 and the adjusting plate 902, when the operator rotates the adjusting plate 902 and drives the three-jaw chuck 901 and the metal compensator to rotate, the rotation angle of the adjusting plate 902 can be observed by using the scale line 904 on the outer surface of the mounting shell 903. This makes it easier to determine the required angular position between adjacent connecting slots of the workpiece and reduces the positional deviation caused by relying entirely on manual visual adjustment.

[0056] Working principle and usage: First, the metal compensator to be processed is installed in the three-jaw chuck. The three-jaw chuck clamps and fixes the metal compensator. The workpiece angle is adjusted according to the initial processing position of the connecting groove. Then, the cam-shaped chuck is rotated by the handle, so that the chuck is pressed against the inner wall of the arc groove, fixing the current position of the adjusting plate and the three-jaw chuck. During processing, the broaching drive mechanism and broaching moving mechanism are started by the control cabinet. The broaching moving mechanism drives the tool holder and broach body to move linearly along the horizontal processing table. The broach body enters the inner hole at the end of the metal compensator and broaches the inner wall, thereby forming the connecting groove. When the broaching of the connecting groove is completed, the broaching moving mechanism drives the broach body to gradually retract to the end of its stroke. The extrusion block installed below the finishing cutter moves synchronously with the broach body and contacts the roller. The extrusion block applies extrusion force to the roller and triggers the limit switch. The limit switch transmits a signal to the control cabinet, which activates the electric telescopic rod, causing the electric telescopic rod to push the toothed plate to move linearly. The toothed plate meshes with the gear, causing the gear to rotate. The gear further drives the rotating rod to rotate, causing the rotating rod to drive the tool holder and the broach body to rotate synchronously. When the electric telescopic rod reaches the set stroke, the tool holder and the broach body complete a 180-degree rotation, causing the finishing cutter to rotate to the position corresponding to the machined connecting groove. Then, the broaching moving mechanism pushes the tool holder to move again, causing the finishing cutter to enter the connecting groove that has been broached, and to finish and deburr the groove wall and groove opening. Meanwhile, after the broach body rotates 180 degrees and faces the cleaning device, as the broaching moving mechanism continues to push the tool holder to move, the push rod fixed below the support plate moves synchronously, driving the rack to move along the horizontal machining table. The rack drives the drive rod to rotate by meshing with the tooth groove on the outer surface of the drive rod. The drive rod drives the circular plate to rotate synchronously. The circular plate drives the cleaning brush to rotate through the slide rod and the mounting plate, so that the cleaning brush brushes and cleans the debris attached to the surface of the broach body and between the teeth. During the cleaning process, the compression spring continuously applies an elastic force to the mounting plate, so that the cleaning brush can maintain contact with the broach body. At the same time as the drive rod rotates, it drives the scraper to rotate synchronously, so that the debris cleaned by the cleaning brush falls onto the arc plate. Under the push of the scraper and the guidance of the arc plate, it gradually moves towards the discharge chute and is discharged into the receiving box for centralized collection.After finishing, the broaching moving mechanism retracts the tool holder and finishing tool. Once the photoelectric sensor detects that the broach body has exited the detection area, it transmits a signal to the control cabinet. The control cabinet then controls the electric telescopic rod to retract, causing the gear plate to move in the opposite direction. This movement, along with the gears and rotating rod, causes the tool holder and broach body to rotate 180 degrees in the opposite direction, returning the broach body to the broaching position. When it's time to continue machining the next connecting slot, the operator rotates the handle to release the clamping plate from the adjusting plate. Then, the three-jaw chuck is rotated, causing the metal compensator to rotate synchronously. The workpiece rotation angle is observed through the scale lines on the outer surface of the mounting housing. Once the workpiece reaches the required machining angle for the next connecting slot, the handle is rotated in the opposite direction to re-clamp the clamping plate against the inner wall of the arc-shaped slot. The broaching, switching, finishing, and cleaning processes are then repeated to complete the continuous machining of multiple connecting slots at the end of the metal compensator.
