Description

Technical Field

[0001] This utility model is specifically a device for machining the stepped surface of a valve block in an automotive brake system, belonging to the field of automotive brake system valve block machining technology. Background Technology

[0002] Brake valves, including pneumatic and hydraulic brake valves, are crucial for vehicle parking. Their proper functioning provides technical support for smooth braking, and the development of this technology is of paramount importance to automobile manufacturing and road safety. The brake valve block is a vital component of the brake valve. The end face of the brake valve's orifice often features stepped holes, which are typically machined using a milling cutter. In the existing technology, in the machining process of the end face stepped hole, it is usually necessary to select the milling cutter of the corresponding diameter according to the size requirements of different parts of the stepped hole. This requires changing the milling cutter of different diameters for machining. Since the connection between the milling cutter and the machining equipment is relatively complex, the replacement is complicated, time-consuming, and reduces the machining efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a machining device for the stepped surface of a valve block in an automotive brake system, in order to solve the above-mentioned problems. This device addresses the issue that the connection between the milling cutter and the machining equipment in the prior art is complex, leading to complicated and time-consuming replacements and reduced machining efficiency.

[0004] This utility model is achieved through the following technical solution: a processing device for the stepped surface of a valve block in an automotive brake system, comprising a worktable, support columns fixed at the four corners of the bottom of the worktable, a fixed frame fixed at the top of the worktable, an electric telescopic rod symmetrically and through the top of the fixed frame, a connecting plate fixed at the output shaft end of the electric telescopic rod, a drive motor fixed through the top of the connecting plate, a mounting plate fixed at the output shaft end of the drive motor, a milling cutter connected to the bottom of the mounting plate, and a disassembly and assembly mechanism connected to the bottom center of the mounting plate; a fixing mechanism is connected to the top of the worktable.

[0005] Preferably, the disassembly and assembly mechanism includes a connecting column connected to the bottom center of the mounting plate, slide rods symmetrically fixed between the two sides of the inner cavity of the connecting column, a slide plate symmetrically sliding on the outer side of the slide rod, a locking block fixed in the center of one side of the slide plate, a connecting seat fixed in the center of the top of the slide plate, a connecting rod rotating inside the connecting seat, a return spring symmetrically fixed in the top of the inner cavity of the connecting column, a moving plate fixed at the bottom of the return spring, a mounting seat symmetrically fixed at the bottom of the moving plate, a connecting sleeve fixed at the top of the milling cutter, and symmetrical slots formed on the inner sidewall of the connecting sleeve.

[0006] Preferably, a through slot is provided through the top center of the fixing frame, and the drive motor is opposite to the through slot, so as to avoid the fixing frame affecting the movement of the drive motor when the drive motor rises.

[0007] Preferably, the locking block extends through the outside of the connecting post, facilitating its removal from the outside of the connecting post. Both sides of the locking block and both sides of the slot are provided with inclined surfaces to allow the locking block to engage with the slot.

[0008] Preferably, one end of the connecting rod rotates inside the mounting base, and the mounting base and the connecting base are linked by the connecting rod. The outer side wall of the moving plate is in contact with the inner side wall of the connecting column to ensure stable movement of the moving plate. The inner diameter of the connecting sleeve is equal to the diameter of the connecting column, so that the connecting sleeve is stably fitted on the outside of the connecting column.

[0009] Preferably, the fixing mechanism includes symmetrically through-grooves extending from the top of the workbench, a limiting rod fixed between the two sides of the groove, a slider sliding on the outer side of the limiting rod, an L-shaped plate fixed to the top of the slider, a clamping plate fixed to one side of the L-shaped plate, a connecting shaft fixed to the bottom center of the slider, symmetrically fixed plates fixed to the bottom of the workbench, connecting rods symmetrically fixed to the opposite sides of the two fixed plates, a moving block sliding on the outer side of the connecting rod, a symmetrically through-grooved groove at the bottom of the moving block, a bearing embedded in the center of one side of the moving block, and a screw threaded through the center of one side of the fixed plate, with a turntable fixed to one end of the screw.

[0010] Preferably, the slider is located inside the groove, and the two sides of the slider are in contact with the two sides of the groove, so that the slider slides stably outside the limiting rod.

[0011] Preferably, one end of the screw is fixed to the inner ring sidewall of the bearing. When the screw rotates, the bearing is used to avoid motion interference between the screw and the moving block. The connecting shaft is located inside the inclined groove. By moving the inclined groove, the connecting shaft moves inside the inclined groove, so that the connecting shafts move closer to each other.

[0012] This utility model provides a device for machining the stepped surface of a valve block in an automotive brake system, which has the following beneficial effects: 1. This application, through the design of a disassembly and assembly mechanism, allows for direct pulling of the connecting sleeve during milling cutter replacement. This causes the inclined surface of the slot to press against the inclined surface of the clamping block, resulting in the clamping block retracting into the inner cavity of the connecting column, allowing the milling cutter to be disassembled. Milling cutters of different diameters can then be installed, with the connecting sleeve fitted onto the outside of the connecting column. This pressing against the inclined surface of the clamping block causes the sliding plate to move the connecting seat, thereby causing the connecting rod to deflect vertically. This raises the moving plate, compressing the return spring and rotating the connecting sleeve. When the clamping block aligns with the slot, the return spring resets the clamping block, embedding it into the slot and completing the replacement. This makes replacement simpler and more convenient, saving time, improving replacement efficiency, and enhancing overall processing efficiency.

[0013] 2. This application uses a fixing mechanism to place the valve block on the worktable. Rotating the turntable drives the screw to rotate, which in turn moves the screw on a fixed plate, causing the moving block to move, which in turn moves the inclined groove. This causes the connecting shaft to move inside the inclined groove, and the two connecting shafts drive the sliders to move closer to each other. This causes the L-shaped plate to drive the clamping plate to move closer to each other, thus fixing the valve block and ensuring its stability during processing. This prevents the valve block from shaking and avoids affecting the processing quality of the valve block. Attached Figure Description

[0016] This utility model provides a device for machining the stepped surface of a valve block in an automotive brake system. Example 1

[0017] A device for machining the stepped surface of a valve block in an automotive brake system includes a worktable 1. Support columns 2 are fixed at the four corners of the bottom of the worktable 1. A fixed frame 3 is fixed at the top of the worktable 1. An electric telescopic rod 301 is symmetrically fixed through the top of the fixed frame 3. A connecting plate 302 is fixed at the end of the output shaft of the electric telescopic rod 301. A drive motor 4 is fixed through the top of the connecting plate 302. A mounting plate 401 is fixed at the end of the output shaft of the drive motor 4. A milling cutter 402 is connected to the bottom of the mounting plate 401. A disassembly and assembly mechanism 5 is connected to the middle of the bottom of the mounting plate 401.

[0018] Please refer to it again. Figure 2 and Figure 3The disassembly and assembly mechanism 5 includes a connecting post 501 connected to the center of the bottom of the mounting plate 401. Slide rods 502 are symmetrically fixed between the two sides of the inner cavity of the connecting post 501. A sliding plate 503 slides symmetrically on the outer side of the slide rods 502. A locking block 504 is fixed to the center of one side of the sliding plate 503. A connecting seat 505 is fixed to the center of the top of the sliding plate 503. A connecting rod 506 rotates inside the connecting seat 505. Return springs 507 are symmetrically fixed to the top of the inner cavity of the connecting post 501. The bottom of the return spring 507... A movable plate 508 is fixed at one end, and a mounting base 509 is symmetrically fixed at the bottom of the movable plate 508. A connecting sleeve 510 is fixed at the top of the milling cutter 402, and slots 511 are symmetrically opened on the inner side wall of the connecting sleeve 510. A through slot is opened through the middle of the top of the fixing frame 3, and the drive motor 4 is opposite to the through slot. A locking block 504 passes through the outside of the connecting column 501, and inclined surfaces are provided on both sides of the locking block 504 and both sides of the slot 511. One end of the connecting rod 506 rotates inside the mounting base 509, moving... The outer wall of the moving plate 508 fits against the inner wall of the connecting post 501, and the inner diameter of the connecting sleeve 510 is equal to the diameter of the connecting post 501. Through the disassembly and assembly mechanism 5, when replacing the milling cutter 402, the connecting sleeve 510 is directly pulled, causing the inclined surface of the slot 511 to press against the inclined surface of the retaining block 504, thereby causing the retaining block 504 to retract into the inner cavity of the connecting post 501, disassembling the milling cutter 402. Then, milling cutters 402 of different diameters are installed, allowing the connecting sleeve 510 to fit onto the connecting post 501. On the outside, the inclined surface of the locking block 504 is pressed, causing the sliding plate 503 to move the connecting seat 505, thereby causing the connecting rod 506 to deflect in the vertical direction, causing the moving plate 508 to rise and press the return spring 507, rotating the connecting sleeve 510. When the locking block 504 is aligned with the slot 511, the return spring 507 resets the locking block 504 into the slot 511, completing the replacement. This makes the replacement simpler and more convenient, saves time, improves the efficiency of replacement, and improves the overall processing efficiency. Example 2

[0019] Please refer to it again. Figure 4 and Figure 5The top of the workbench 1 is connected to a fixing mechanism 6. The fixing mechanism 6 includes a symmetrically through-cut groove 601 on the top of the workbench 1. A limit rod 602 is fixed between the two sides of the groove 601. A slider 603 slides on the outer side of the limit rod 602. An L-shaped plate 604 is fixed on the top of the slider 603. A clamping plate 605 is fixed on one side of the L-shaped plate 604. A connecting shaft 606 is fixed in the middle of the bottom of the slider 603. Fixing plates 607 are symmetrically fixed on the bottom of the workbench 1. Connecting rods 608 are symmetrically fixed on opposite sides of the two fixing plates 607. A moving block 609 slides on the outer side of the connecting rod 608. A symmetrically through-cut inclined groove 610 is provided on the bottom of the moving block 609. A bearing 611 is embedded in the middle of one side of the moving block 609. A screw 612 is threaded through the middle of one side of a fixing plate 607. One end of the 2 is fixed with a turntable 613; the slider 603 is located inside the slide groove 601, and the two sides of the slider 603 are in contact with the two sides of the slide groove 601; one end of the screw 612 is fixed to the inner ring side wall of the bearing 611, and the connecting shaft 606 is located inside the inclined groove 610; by setting the fixing mechanism 6, the valve block is placed on the worktable 1, the turntable 613 is rotated, the screw 612 is driven to rotate, so that the screw 612 moves on a fixed plate 607, drives the moving block 609 to move, so that the inclined groove 610 moves, and the connecting shaft 606 moves inside the inclined groove 610, so that the two connecting shafts 606 drive the slider 603 to move closer to each other, so that the L-shaped plate 604 drives the clamping plate 605 to move closer to each other, and fixes the valve block to ensure the stability of the valve block during processing, avoids the valve block shaking, and prevents the valve block processing quality from being affected.

[0020] When using this utility model: Working principle: Connect the electrical components to an external power supply and control switch. Then, place the valve block on the worktable 1. Rotate the turntable 613, which drives the screw 612 to rotate. This causes the screw 612 to move on a fixed plate 607, which in turn moves the moving block 609. This moves the inclined groove 610, causing the connecting shaft 606 to move inside the inclined groove 610. This causes the two connecting shafts 606 to move the slider 603 closer together, which in turn causes the L-shaped plate 604 to move the clamping plate 605 closer together, thus fixing the valve block. When machining the stepped surface of the hole, start the drive motor 4 to rotate the milling cutter 402. Then, lower the electric telescopic rod 301, which in turn lowers the milling cutter 402 to mill the valve block. Afterward, retract the electric telescopic rod 301, turn off the power, replace the large-diameter milling cutter 402, and pull the connecting sleeve 510 to open the slot. The inclined surface of 511 presses against the inclined surface of the locking block 504, causing the locking block 504 to retract into the inner cavity of the connecting post 501. The milling cutter 402 is then removed, and milling cutters 402 of different diameters are installed. The connecting sleeve 510 is fitted onto the outside of the connecting post 501, pressing against the inclined surface of the locking block 504. This causes the sliding plate 503 to move the connecting seat 505, thereby causing the connecting rod 506 to deflect vertically, raising the moving plate 508 and pressing against the return spring 507. The connecting sleeve 510 is rotated, and when the locking block 504 is aligned with the slot 511, the return spring 507 resets the locking block 504, allowing it to be embedded in the slot 511, completing the replacement. The drive motor 4 is restarted to rotate the milling cutter 402, and the electric telescopic rod 301 is activated to lower the milling cutter 402, milling the top of the previously machined hole, thus completing the step surface machining.
