Description

Technical Field

[0001] This utility model relates to a grinding device, specifically a grinding device for valve block channels in an automotive brake system, belonging to the field of automotive brake system valve block processing technology. Background Technology

[0002] The valve block of an automotive brake system is a key control component in the brake system. It is a metal block with multiple channels and mounting interfaces. The internal channels are interconnected to provide flow channels for brake fluid. Various valves, sensors and other components can be installed on the outside. It is the core carrier of hydraulic control in the brake system. The channels of the valve block need to be ground during processing.

[0003] Chinese Patent Publication No. CN221111029U discloses a grinding device for the inner hole of a metal part. The grinding device includes a worktable, on which a placement plate is vertically fixedly installed. A motor is fixedly installed on the placement plate, and the output shaft of the motor is threadedly connected to the mounting plate. A baffle is also fixedly installed on the worktable, and the baffle is symmetrically installed on both sides of the mounting plate. This utility model is provided with a collection box, which is slidably mounted on a top block. The top block is mounted on a spring. When the amount of powder accumulated in the collection box is the largest, the spring is compressed to the highest degree, causing the extension rod connected to the top block to press down on one end of the extension rod that cooperates with the swing rod. The extension rod then rotates, causing the other end to rise. At this time, this end of the extension rod rises until it no longer abuts against the push plate.

[0004] However, the inventor of the above device believes that there are certain defects. The above device uses conventional fixed-size grinding blocks, which are not convenient to adapt to channels with different diameters (such as the multi-stage diameter of ABS valve blocks). Frequent replacement of the corresponding grinding blocks reduces grinding efficiency. Therefore, this utility model provides a grinding device for valve block channels of automotive brake systems. Summary of the Invention

[0005] (a) Technical problems to be solved The purpose of this invention is to provide a grinding device for valve block channels in automotive brake systems to solve the above-mentioned problems, thereby addressing the issues in the prior art where it is inconvenient to adapt to channels of different diameters, requiring frequent replacement of the corresponding grinding blocks and reducing grinding efficiency.

[0006] (II) Technical Solution This utility model is achieved through the following technical solution: a grinding device for valve block channels in an automotive brake system, comprising a base, a lifting seat, and a grinding mechanism. The grinding mechanism includes a connecting cylinder rotating on the lifting seat. An upper mounting plate and a lower mounting plate are fixedly connected to the outer surface of the connecting cylinder. Multiple arc-shaped grinding blocks in a circumferential array are slidably connected between the upper mounting plate and the lower mounting plate. A connecting frame is fixedly connected to the inner sidewall of each arc-shaped grinding block. An inner sliding groove is provided on the connecting frame. A through sliding groove is provided on the outer surface of the connecting cylinder. Two extrusion frames are slidably connected inside the connecting cylinder. A connecting slide rod is fixedly connected to each of the four ends of each extrusion frame. The two ends of the connecting slide rod slide inside the two sets of inner sliding grooves respectively. A bidirectional screw is rotatably connected inside the connecting cylinder. Both extrusion frames are threadedly connected to the bidirectional screw. A limiting mechanism is provided at one end of the bidirectional screw to restrict its rotation.

[0007] Preferably, a support frame is fixedly connected to the top of the base, and a first slide rod is fixedly connected inside the support frame. One end of the lifting seat is slidably connected to the first slide rod, and the support frame and the first slide rod support the support frame to slide up and down directly above the base.

[0008] Preferably, a lifting screw is rotatably connected inside the support frame, one end of the lifting seat is threaded to the lifting screw, and a first motor that drives the lifting screw to rotate is fixedly connected to the top of the support frame. By starting the first motor, the lifting screw is controlled to rotate, thereby driving the lifting seat to adjust its height.

[0009] Preferably, a drive box is fixedly connected to one end of the lifting seat, the connecting drum extends into the interior of the drive box, a worm wheel is fixedly connected to the outer surface of the connecting drum, a worm is rotatably connected inside the lifting seat, the worm meshes with the worm wheel, and a second motor is fixedly connected to the lifting seat to drive the worm to rotate. By starting the second motor, the worm is driven to rotate, and the connecting drum is driven to rotate under the meshing action of the worm and the worm wheel.

[0010] Preferably, the limiting mechanism includes a first locking block fixed to the outer surface of one end of the connecting drum, a second locking block adapted to the first locking block fixedly connected to the outer surface of the bidirectional screw, and a sliding sleeve sliding on one end of the bidirectional screw. By driving the sliding sleeve to slide downward at one end of the bidirectional screw, the first locking block slides into the groove on the inner side wall of the sliding sleeve, thereby limiting the individual rotation of the bidirectional screw.

[0011] Preferably, the top of the base is fixedly connected to two fixed seats, and each of the two fixed seats has a clamping plate slidably connected to one side that is close to the other, so that the valve block is clamped and fixed by the two clamping plates.

[0012] Preferably, one side of the fixed base is threaded with an adjusting screw, and the clamping plate is rotatably connected to one end of the adjusting screw. By rotating the adjusting screw, the clamping plate is pushed to slide closer to the center of the base.

[0013] Preferably, a cover is installed at one end of the drive box. The cover is detachably connected to one end of the drive box by bolts. By removing the cover at one end of the drive box, it is convenient to perform maintenance and repair on its interior.

[0014] This utility model provides a device for grinding valve block channels in automotive brake systems, which has the following beneficial effects: 1. This device controls the lowering of the lifting seat, allowing one end of the grinding mechanism to extend into the channel of the valve block. By driving the bidirectional screw to rotate, the two extrusion frames slide away from each other. Under the action of the connecting slide rod, inner slide groove, and connecting frame, multiple arc-shaped grinding blocks are pushed outward to slide, making the arc-shaped grinding blocks in close contact with the inner wall of the channel. This drives the connecting drum to rotate and grind the channel. By controlling the sliding distance of the arc-shaped grinding blocks, it can meet the grinding operation of channels of different sizes, and has good adaptability.

[0015] 2. This device controls the sliding sleeve to slide downwards at one end of the bidirectional screw, causing the second locking block to slide into the groove on the inner wall of the sliding sleeve, thereby limiting the individual rotation of the bidirectional screw and restricting its rotation inside the connecting drum. This improves the stability of the arc-shaped grinding block after adjustment. By driving the two clamping plates to move closer to each other, the valve block can be quickly clamped and fixed.

T-shaped sliders are fixedly connected to both ends of the arc-shaped grinding blocks 5. The T-shaped sliders slide inside the T-shaped grooves, and the inner wall of the channel is ground by the arc-shaped grinding blocks 5.

[0020] Please refer to it again. Figure 1 , Figure 2 and Figure 3 A connecting frame 6 is fixedly connected to the inner wall of the arc-shaped grinding block 5. The connecting frame 6 has an inner sliding groove 61. The two sets of inner sliding grooves 61 are arranged in a V shape. The cross-section of the connecting frame 6 is U-shaped. A through sliding groove 43 is opened on the outer surface of the connecting drum 4. Two extrusion frames 7 are slidably connected inside the connecting drum 4. Each extrusion frame 7 has a connecting slide rod 71 fixedly connected to its four ends. The extrusion frame 7 is cross-shaped. The four ends of the extrusion frame 7 extend to the outside of the drum 4 through the through sliding groove 43. The two ends of the connecting slide rod 71 slide inside the two sets of inner sliding grooves 61 respectively. A bidirectional screw 8 is rotatably connected inside the connecting drum 4. Both extrusion frames 7 are threadedly connected to the bidirectional screw 8. The bidirectional screw 8 is a screw with two external threads. The two external threads are in opposite directions. By rotating the bidirectional screw 8, the two extrusion frames 7 can slide closer to each other or further away from each other. By pressing the inner sliding groove 61 with the connecting slide rod 71, the arc-shaped grinding block 5 is pushed to slide outward or retract inward. Example 2

[0021] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 5 A support frame 2 is fixedly connected to the top of the base 1. A first slide rod is fixedly connected inside the support frame 2. One end of the lifting seat 3 is slidably connected to the first slide rod. A lifting screw 21 is rotatably connected inside the support frame 2. One end of the lifting seat 3 is threadedly connected to the lifting screw 21. A first motor 22 that drives the lifting screw 21 to rotate is fixedly connected to the top of the support frame 2. The first motor 22 is started to drive the lifting screw 21 to rotate, thereby driving the lifting seat 3 to move up and down and slide as a whole.

[0022] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 5 One end of the lifting seat 3 is fixedly connected to a drive box 31. The connecting drum 4 extends into the drive box 31. A worm wheel 32 is fixedly connected to the outer surface of the connecting drum 4. A worm 34 is rotatably connected inside the lifting seat 3. The worm 34 meshes with the worm wheel 32. A second motor 35 is fixedly connected to the lifting seat 3 to drive the worm 34 to rotate. The second motor 35 is started to drive the worm 34 to rotate. The meshing action of the worm 34 and the worm wheel 32 drives the connecting drum 4 to rotate.

A cover is installed at one end of the drive box 31. The cover is detachably connected to one end of the drive box 31 by bolts. By removing the bolts on the cover, one end of the lifting seat 3 can be opened to perform maintenance and repair on the inside of the lifting seat 3. Example 3

[0023] Please refer to it again. Figure 1 , Figure 4 and Figure 6 One end of the bidirectional screw 8 is provided with a limiting mechanism to restrict the rotation of the bidirectional screw 8. The limiting mechanism includes a first locking block 44 fixed to the outer surface of one end of the connecting drum 4.

A sliding sleeve 9 slides on one end of the bidirectional screw 8. The interior of the sliding sleeve 9 is provided with a circular groove and a rectangular groove around the circular groove. After adjustment, the second locking block 81 is aligned with the first locking block 44, and then the sliding sleeve 9 is driven to slide down to connect one end of the bidirectional screw 8 to the connecting drum 4, thereby restricting the rotation of the bidirectional screw 8 during the rotation of the connecting drum 4.

[0024] Please refer to it again. Figure 1 , Figure 4 and Figure 6The top of the base 1 is fixedly connected to two fixed seats 11. Each fixed seat 11 has a clamping plate 12 slidably connected to one side of its close proximity. An adjusting screw 13 is threadedly connected to one side of the fixed seat 11. The clamping plate 12 is rotatably connected to one end of the adjusting screw 13. Rubber pads are provided on the close sides of the two clamping plates 12. By rotating the adjusting screw 13, the clamping plate 12 is pushed to slide closer to the center of the base 1. The valve block is clamped and fixed by the two clamping plates 12. A second sliding rod is fixedly connected to one side of the clamping plate 12. The second sliding rod slides on the fixed seat 11.

[0025] Working principle: Install the device in a suitable location and connect it to the municipal power supply. Place the valve block on top of the base 1, so that the hole to be ground is directly below the grinding mechanism. Start the first motor 22 to drive the lifting screw 21 to rotate, causing the grinding mechanism to descend, so that one end of the connecting drum 4 extends into the hole. Rotate the bidirectional screw 8 to drive the two extrusion frames 7 to slide away from each other. The connecting slide rod 71 extrudes the inner slide groove 61, pushing multiple arc-shaped grinding blocks 5 to slide outward, so that the arc-shaped grinding blocks 5 are in contact with the hole. After the inner wall of the channel is in close contact and the adjustment is completed, the second locking block 81 is aligned with the first locking block 44. Then, the sliding sleeve 9 is driven to slide down to connect one end of the bidirectional screw 8 to the connecting drum 4. By rotating the adjusting screw 13, the clamping plate 12 is pushed to slide towards the valve block. The valve block is clamped and fixed by the two clamping plates 12. The second motor 35 is started to drive the worm 34 to rotate. Under the meshing action of the worm 34 and the worm wheel 32, the connecting drum 4 is driven to rotate as a whole to polish the valve block channel.
