Description

Technical Field

[0001] This invention relates to the field of honing equipment technology, specifically to a cylinder bore honing device for brake caliper machining. Background Technology

[0002] The automotive braking system is a core component ensuring vehicle safety. As a key actuator in the braking system, the machining accuracy, surface roughness, and dimensional tolerances of the brake caliper's cylinder bore directly determine its sealing performance, operational reliability, and ultimately, the overall braking safety of the vehicle. Honing is a core process for the precision machining of the inner surface of the brake caliper cylinder bore and is widely used in the industrial mass production of brake calipers. The operational stability, machining accuracy, and production efficiency of honing equipment directly determine the manufacturing cost and product quality of brake calipers. As the automotive industry continues to demand higher performance consistency and production efficiency for braking components, the industry is placing even more stringent requirements on the operational reliability, protective performance, and continuous production capacity of brake caliper cylinder bore honing equipment.

[0003] Existing honing equipment for brake caliper cylinder bores mostly employs a multi-axis linkage workpiece feeding structure combined with a honing mechanism to achieve precision machining of the cylinder bores. It also includes a cooling system and chip collection structure to handle cooling, lubrication, and chip collection during the machining process. However, this type of equipment has a long transmission chain and numerous moving pairs in its multi-axis feeding structure. Metal chips generated during honing are easily scattered and fall into the clearances of the equipment's transmission structure. Long-term use can cause guide rail wear and transmission jamming, continuously reducing the equipment's feeding and positioning accuracy, significantly shortening its lifespan, and increasing maintenance costs and unplanned downtime. Furthermore, existing cooling and chip collection structures cannot coordinate effectively with the workpiece feeding and machining actions, leading to continuous chip accumulation in the machining area. This requires frequent manual shutdowns for cleaning, making it difficult to achieve long-term continuous mass production. It also fails to provide continuous and effective protection for the core transmission structure, making it unsuitable for the high-precision, high-stability, and high-efficiency industrial mass production requirements of automotive brake components.

[0004] Therefore, there is an urgent need to develop a dedicated honing machine adapted for machining brake caliper cylinder bores to solve the above problems. Summary of the Invention

[0012] When the above technical solution is adopted, the U-shaped sheet metal protective frame achieves complete shielding of splashing debris in the honing area through the closed right side and front and rear side panels. Its opening facing the temporary storage tank is precisely aligned with the opening of the temporary storage tank, so that the coolant mixed with debris falls directly into the temporary storage tank without obstruction. It has the advantages of good anti-splash effect and smooth flow of debris.

[0013] Preferably, the scraper is a scraper made of wear-resistant polyurethane material. The bottom of the scraper is slidably attached to the inner bottom surface of the temporary storage tank, and the front and rear sides of the scraper are slidably attached to the inner sidewall of the temporary storage tank. The inner wall of the chute is provided with a wear-resistant bushing, which slides and fits against both sides of the baffle. The length of the baffle is greater than the effective stroke of the guide rail frame.

[0014] When the above technical solution is adopted, the wear-resistant polyurethane scraper slides and fits against the inner wall of the temporary storage tank, realizing the comprehensive scraping and cleaning of debris in the temporary storage tank during the movement of the slider. It has the advantages of good wear resistance and thorough debris removal. The wear-resistant bushing on the inner wall of the slide reduces the wear of the slider during movement. The baffle with a length greater than the effective stroke of the guide rail frame realizes the protection of the transmission screw without dead angles throughout the entire stroke of the slider, which has the advantages of long-lasting protection and long service life of the equipment.

[0015] Preferably, the driving component is a servo motor, and the transmission screw is a ball screw; The guide rail frame is a closed linear guide rail structure.

The workpiece positioning component consists of at least four positioning rods, the arrangement of which corresponds one-to-one with the standard mounting holes of the caliper to be processed, and the top of each positioning rod is provided with a guide chamfer.

[0016] When the above technical solution is adopted, the servo motor and ball screw realize the high-precision and high-response feeding and positioning of the slider.

[0017] Preferably, holes are provided on both sides of the top of the loading frame and insert pipes are embedded therein, and a hole is provided on the top of the loading frame between the two insert pipes and an installation groove is embedded therein; The inner bottom surface of the temporary storage tank is provided with an inclined angle to accelerate chip removal towards the waste discharge hole.

[0018] When the above technical solution is adopted, the plug pipe on the loading frame provides stable installation and positioning for the coolant delivery pipeline, and the mounting groove provides a precise installation reference for the honing mechanism, realizing the integrated installation of various functional components; the inclination angle of the bottom surface of the inner side of the temporary storage tank accelerates the flow of coolant mixed with debris toward the waste discharge hole, realizing the rapid discharge of debris, and has the advantages of high chip removal efficiency and no debris retention.

[0019] Preferably, the honing mechanism includes a drive motor, a transmission pulley set, a lifting cylinder, a honing spindle, and a sizing honing head. The drive motor is fixed to the top of the loading frame via a bracket, and the output end of the drive motor is connected to the honing spindle via the transmission pulley set. The lifting cylinder is fixed in the mounting groove of the loading frame, and the piston rod end of the lifting cylinder is fixedly connected to the bearing seat of the honing spindle. The sizing honing head is fixed to the lower end of the honing spindle, and a honing oilstone is fixedly installed on the outer wall of the sizing honing head.

[0020] When the above technical solution is adopted, the honing mechanism drives the honing spindle to rotate through a drive motor and a transmission pulley set. The honing spindle and the sizing honing head are vertically fed through a lifting cylinder, realizing the sizing honing of the brake caliper cylinder bore. This eliminates the traditional radial expansion tool structure and has the advantages of simple structure, stable machining action, and suitability for blind hole cylinder body machining. The honing stone on the outer wall of the sizing honing head realizes high-precision finishing of the inner wall of the cylinder bore, which has the advantages of high machining accuracy and good product consistency.

[0021] Preferably, the coolant delivery mechanism includes a circulation pump and a delivery pipeline. The circulation pump is connected to the flange of the liquid storage chamber at the bottom of the frame body. The delivery pipeline includes a main pipeline and two branch pipelines. The two branch pipelines are respectively inserted into the insertion pipes on both sides of the loading frame. The liquid outlet of the branch pipeline faces the cylinder bore opening of the caliper to be processed. A throttle valve is provided on the branch pipeline. The inner side of the insertion pipe is provided with a sealing bushing, and the sealing bushing is interference-fitted with the outer wall of the delivery pipeline.

[0022] When the above technical solution is adopted, the circulating pump of the coolant delivery mechanism, together with the delivery pipeline, realizes the continuous circulation supply of coolant in the honing area.

It has the advantages of strong processing adaptability and convenient process adjustment.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention simplifies the overall structure of the equipment and improves operational stability by setting up a single-degree-of-freedom horizontal conveying mechanism.

[0026] This solution abandons the multi-axis linkage workpiece feeding structure of existing honing equipment. It only uses a single-degree-of-freedom horizontal conveying mechanism composed of a guide rail frame, drive component, slider, and transmission screw to complete the feeding and positioning of the caliper to be processed. This significantly shortens the equipment transmission chain, reduces the number of moving pairs, fundamentally simplifies the equipment structure, and reduces the probability of equipment failure. The workpiece positioning component set on the slider can realize the rapid and accurate positioning of the caliper to be processed, further improving the efficiency and accuracy of feeding and positioning. It realizes the core advantages of simplified and stable structure and effectively solves the problems of long transmission chains and complex structures in the multi-axis feeding structure of existing honing equipment.

[0027] This invention achieves reliable protection for the core transmission components of the equipment throughout their entire stroke by setting up baffles, slides, and protective frames.

[0028] A vertically fixed baffle on the bearing mechanism passes through a groove on the front of the slider, providing continuous protection for the transmission screw throughout the slider's entire stroke. This structurally prevents metal chips generated during honing from entering the clearance of the transmission screw, avoiding problems such as guide rail wear and transmission jamming. At the same time, the protective frame fixed on the outside of the slider can shield and restrain splashing chips in the processing area, further reducing the spread of chips to the transmission components. This achieves the advantage of reliable transmission protection and effectively solves the problem of existing honing equipment where chips easily enter the transmission pair, causing component wear and short equipment life.

[0029] This invention achieves a highly efficient coordination between chip removal and feeding processes by setting a chip collection groove directly opposite the protective frame and a chip scraper that moves synchronously with the slider.

[0030] The top and one side of the protective frame are open structures, and the openings are directly opposite the openings of the chip collection groove on the supporting mechanism. The coolant from the mixed chips generated during honing can fall directly into the chip collection groove, achieving directional collection of chips. At the same time, the scraper fixed to the side of the slider facing the chip collection groove is adapted to the inner cavity of the chip collection groove. As the slider moves forward with the horizontal conveyor mechanism to reset, it can simultaneously drive the scraper to clean the chips in the chip collection groove. No additional drive components are required, and there is no need for frequent manual stops for cleaning. This achieves pure mechanical coordination between chip removal and processing actions, which can ensure long-term continuous batch production of the equipment and effectively solve the problem of existing honing equipment where chip removal and processing actions are disconnected and frequent manual stops for cleaning are required.

[0031] This invention achieves the effect of further simplifying processing operations and improving chip removal efficiency by setting a honing mechanism fixed to the bearing mechanism and a coolant delivery mechanism with the liquid outlet facing the processing area.

[0032] The honing head of the honing mechanism is matched with the inner diameter of the cylinder bore to be machined in the caliper. The cylinder bore can be machined by simply feeding vertically downwards, without the need for additional horizontal displacement adjustment, which further simplifies the equipment's operating structure. At the same time, it makes the chip discharge path generated by honing stable and controllable. With the directional chip flushing of the coolant delivery mechanism, the chips generated during processing can be flushed into the chip collection groove in a timely manner, which further improves the processing stability and chip removal efficiency of the equipment.

The loading frame 23 is detachably installed at the rear end of the upper end face of the working platform 21. The connector 23 is installed by inserting holes on both sides of the top of the loading frame 23. The top of the loading frame 23 between the two connectors 232 is opened and the installation groove 231 is installed. The end of the conveying pipe 51 away from the circulating pump 52 passes through the connector 232 and extends into the frame body 1 for injecting liquid into the processing area. A baffle 24 is vertically installed on the front of the loading frame 23. The horizontal conveying mechanism 3 includes a guide rail frame 31, a servo motor 32, a slider 33, a protective frame 331, a positioning rod 332, a scraper 333, and a chute 334. The guide rail frame 31 is fixedly installed in the middle of the upper end face of the work platform 21. A servo motor 32 is installed at one end of the guide rail frame 31, and a slider 33 is slidably installed on the guide rail frame 31. The slider 33 is connected to the output end of the servo motor 32 via a ball screw. A protective frame 331 is fixedly installed on the outside of the slider 33. The top and left side of the protective frame 331 are open, with the left side opening directly opposite the opening of the temporary storage tank 22, allowing the coolant mixed with debris to fall into the temporary storage tank 22. The slider is located inside the protective frame 331. A positioning rod 332 is fixedly installed on the slider 33. The positioning rod 332 passes through the mounting hole on the caliper 6 to be processed and is used to limit the position of the caliper 6 to be processed on the slider 33. A scraper 333 is fixedly installed on the side of the slider 33 facing the temporary storage groove 22. The size of the scraper 333 matches the inner cavity size of the temporary storage groove 22 and is used to scrape the debris and coolant in the temporary storage groove 22 to the waste discharge hole 221 at the front end. A through-type slide groove 334 is opened on the front of the slider 33. A baffle 24 passes through the slide groove 334 and is fixed relative to the position of the frame body 1. When the slider 33 slides along the guide rail frame 31, the baffle 24 provides continuous shielding protection for the ball screw. The honing mechanism 4 is fixedly installed on the loading frame 23. The outer diameter of the honing head of the honing mechanism 4 matches the inner diameter of the cylinder bore to be processed in the caliper 6. The honing mechanism 4 drives the honing head to feed vertically downward, and the honing and finishing of the cylinder bore is completed by the rotation of the honing head.

[0037] Specifically, the horizontal conveying mechanism 3 in this embodiment is a single-degree-of-freedom feeding structure, which completes the feeding and positioning of the caliper 6 to be processed only through the guide rail frame 31, servo motor 32, slider 33 and ball screw; The honing head of the honing mechanism 4 is a fixed-sizing structure with no radial expansion adjustment action, and the cylinder bore honing is completed only by vertical feed; The baffle 24 cooperates with the slide groove 334 of the slider 33 to block the ball screw during the full stroke of the slider 33. The opening of the protective frame 331 is directly opposite the temporary storage tank 22. The scraper 333 moves synchronously with the slider 33, and the debris in the temporary storage tank 22 is cleaned during the movement of the slider 33.

[0038] Example 2: To limit the installation position of the caliper to be processed, to shield against processing debris, and to protect the transmission components, such as... Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment, the guide rail frame 31 of the horizontal conveying mechanism 3 adopts a closed linear guide rail structure. Dustproof grooves are provided on both sides of the guide rail frame 31. A dustproof scraper is provided at the bottom of the slider 33 corresponding to the dustproof groove. The dustproof scraper slides and fits in contact with the inner wall of the dustproof groove. The dustproof scraper is made of wear-resistant nylon material. It slides and adheres to the inner wall of the dustproof groove during the movement of the slider 33 to clean the debris in the dustproof groove.

[0039] At least four positioning rods 332 are provided on the slider 33, and the arrangement of the positioning rods 332 corresponds one-to-one with the standard mounting hole positions of the caliper 6 to be processed. The top of the positioning rods 332 is provided with a guide chamfer. After the slider 33 moves backward to the processing position, the position of the cylinder hole to be processed of the caliper 6 to be processed corresponds coaxially with the honing head axis of the honing mechanism 4.

[0040] The protective frame 331 adopts a U-shaped sheet metal structure. The bottom of the protective frame 331 is bolted to the slider 33. The right side, front and rear sides of the protective frame 331 are closed panels, while the top and left side are open structures. The bottom edge of the left open is flush with the upper edge of the opening of the temporary storage tank 22, and the width of the left open covers the opening width of the temporary storage tank 22. The top opening of the protective frame 331 allows the honing head of the honing mechanism 4 to pass through without interference, and the height of the front and rear side plates of the protective frame 331 is higher than the cylinder bore opening end face of the caliper 6 to be processed.

[0041] The scraper 333 on the side of the slider 33 facing the temporary storage tank 22 is made of wear-resistant polyurethane. The bottom of the scraper 333 slides against the inner bottom surface of the temporary storage tank 22, and the front and rear sides of the scraper 333 slide against the inner wall of the temporary storage tank 22. When the slider 33 moves back and forth along the guide rail frame 31, it synchronously drives the scraper 333 to perform reciprocating scraping motion in the temporary storage tank 22. When the slider 33 moves forward to reset after processing, the scraper 333 scrapes the debris and coolant in the temporary storage tank 22 to the waste discharge hole 221 at the front end. The inner wall of the groove 334 on the front of the slider 33 is provided with a wear-resistant bushing. The wear-resistant bushing slides and fits against both sides of the baffle 24. The length of the baffle 24 is greater than the effective stroke of the guide rail frame 31.

[0042] Specifically, the positioning rod 332 passes through the mounting hole of the caliper 6 to be processed, thus completing the positioning of the caliper 6 on the slider 33; The closed plate of the U-shaped protective frame 331 blocks the debris that splashes during honing, while the left side opening allows the coolant mixed with debris to flow into the temporary storage tank 22. The scraper 333 moves synchronously with the reset action of the slider 33, scraping the debris and coolant in the temporary storage tank 22 into the waste discharge hole 221; During the full stroke of the slider 33, the baffle 24 continuously blocks the ball screw.

Figure 1 , Figure 2 , Figure 4 , Figure 8 and Figure 9 As shown, in this embodiment, the coolant delivery mechanism 5's delivery pipeline 51 includes a main pipeline and two branch pipelines. The two branch pipelines pass through the insertion pipes 232 on both sides of the loading frame 23. The outlet end of the branch pipeline faces the cylinder bore opening of the caliper 6 to be processed. During honing, the coolant is sprayed through the branch pipelines to the mating area between the cylinder bore opening and the honing head, flushing the debris brought out by the honing head from the cylinder bore. The flushed coolant mixed with the debris falls into the temporary storage tank 22 through the left opening of the protective frame 331.

[0044] The bottom inner side of the temporary storage tank 22 of the bearing mechanism 2 is provided with an inclination angle of 1° to 3° towards the waste discharge hole 221 at the front end; The bottom of the waste discharge hole 221 corresponds to the top opening of the filter frame 12. The filter frame 12 adopts a drawer-type structure and can be pulled out from the bottom open slot on the front of the housing 11. The inner side of the filter frame 12 is provided with multiple layers of stainless steel filter screens for graded filtration of metal debris in the coolant. The filtered coolant falls into the liquid storage chamber at the bottom of the inner side of the housing 11. The liquid storage chamber is connected to the inlet of the circulation pump 52 through a pipe to form a closed-loop circulation system of coolant. The mesh size of the multi-layer stainless steel filter increases progressively along the flow direction of the coolant, thus classifying and intercepting metal debris of different sizes.

[0045] A sealing bushing is provided on the inner side of the insertion pipe 232 on the loading frame 23, and the sealing bushing is interference-fitted with the outer wall of the conveying pipe 51. A throttle valve is installed on a branch pipe of the delivery pipeline 51 to regulate the injection flow rate and pressure of the coolant; The balance feet 13 at the bottom of the frame body 1 adopt a height-adjustable structure, and the support height can be adjusted by thread; The bottom of the balance foot support 13 is equipped with an anti-slip rubber pad to reduce vibration during equipment operation.

[0046] Specifically, the two branch pipes of the delivery pipe 51 simultaneously spray coolant from both sides of the cylinder bore opening to flush away the debris generated during processing. The inclined bottom surface of the temporary storage tank 22 guides the coolant and debris to flow towards the waste discharge hole 221; The filter frame 12 filters out debris from the coolant, and the filtered clean coolant flows back to the storage chamber and is then pumped back to the processing area by the circulation pump 52, forming a circulation path.

[0047] Example 4: To achieve honing of the brake caliper cylinder bore, such as... Figure 1 , Figure 3 and Figure 8 As shown, in this embodiment, the honing mechanism 4 includes a drive motor, a transmission pulley set, a lifting cylinder, a honing spindle, and a sizing honing head; The drive motor is fixedly mounted on the top of the loading frame 23 by a bracket. The output end of the drive motor is connected to the honing spindle through a transmission belt pulley set to drive the honing spindle to rotate the sizing honing head. The lifting cylinder is fixedly installed in the mounting slot 231 of the loading frame 23. The piston rod end of the lifting cylinder is fixedly connected to the bearing seat of the honing spindle. It is used to drive the honing spindle and the sizing honing head to be vertically lifted and fed as a whole. The overall position of the honing mechanism 4 is fixed, and the vertical feeding action of the honing head is achieved only through the lifting cylinder. A protective cover needs to be installed on the outside of the transmission belt pulley assembly to shield the transmission components.

[0048] A honing stone is fixedly installed on the outer wall of the sizing honing head. The outer diameter of the honing stone is perfectly matched with the inner diameter of the cylinder bore of the caliper 6 to be processed. The length of the sizing honing head is adapted to the depth of the cylinder bore to be processed. The front end of the sizing honing head is provided with a guide radius.

[0049] The stroke of the lifting cylinder is matched with the depth of the cylinder bore to be processed. The air inlet of the lifting cylinder is equipped with a speed regulating valve to adjust the feed speed of the honing head. The drive motor is a variable frequency speed control motor, which can adjust the rotation speed of the honing spindle.

[0050] Specifically, the drive motor drives the honing spindle and the sizing honing head to rotate through the transmission belt pulley set. The lifting cylinder drives the rotating sizing honing head to feed vertically downward and extend into the cylinder hole of the caliper 6 to complete the honing process. During the honing process, the sizing honing head engages with the inner wall of the cylinder bore to carry away the honing debris from the opening end of the cylinder bore.

[0051] When using this invention, first place the equipment at the processing station, and adjust the balance feet 13 at the bottom of the frame body 1 to keep the entire equipment level. Confirm that the delivery pipe 51 of the coolant delivery mechanism 5 is securely connected, and that the inlet end of the circulation pump 52 is connected to the storage chamber at the bottom of the housing 11. Add honing-specific coolant to the storage chamber. The filter screen frame 12 is fitted inside the housing 11, and the opening of the filter screen frame 12 corresponds vertically to the waste discharge hole 221 at the front end of the temporary storage tank 22. Confirm that the slider 33 of the horizontal conveying mechanism 3 is in the front material loading / unloading position, the lifting cylinder of the honing mechanism 4 is in the reset state, the sizing honing head is in the highest position, and there is no movement interference. Confirm that the baffle 24 passes through the groove 334 of the slider 33, and the scraper 333 extends into the temporary storage groove 22 and fits against the bottom of the groove.

[0052] When loading the workpiece, align the mounting hole of the caliper 6 to be processed with the positioning rod 332 on the slider 33, place the caliper 6 to be processed on the slider 33, and the positioning rod 332 passes through the mounting hole of the caliper 6 to be processed to complete the workpiece positioning.

[0053] When the equipment is started, the servo motor 32 operates, driving the slider 33 to move backward along the guide rail 31 via the ball screw. This transports the caliper 6 to be processed from the pick-and-place position to the processing station directly below the honing mechanism 4. Once in position, the servo motor 32 stops, completing the workpiece feeding and positioning. During the backward movement of the slider 33, the baffle 24 continuously blocks the ball screw through the groove 334.

[0054] After the workpiece is positioned, the drive motor of the honing mechanism 4 starts, driving the honing spindle and the sizing honing head to rotate via the transmission pulley set. At the same time, the lifting cylinder drives the honing spindle and the sizing honing head to feed vertically downwards, so that the sizing honing head extends into the cylinder bore of the caliper 6 to be processed, completing the honing finish of the cylinder bore. During the processing, the circulation pump 52 of the coolant delivery mechanism 5 runs continuously, delivering the coolant in the storage chamber to the processing area through the delivery pipeline 51, and spraying it from the outlet end of the branch pipeline to the mating area between the cylinder bore opening and the honing head, flushing away the metal chips brought out by the honing head from the cylinder bore. The coolant mixed with debris falls into the temporary storage tank 22 through the opening on the left side of the protective frame 331.

[0055] After processing is completed, the lifting cylinder drives the honing spindle and the sizing honing head to return to their vertical position, and the drive motor stops running; The servo motor 32 rotates in reverse, driving the slider 33 to move forward along the guide rail frame 31, conveying the processed brake caliper back to the material pick-up and drop-off position. During the forward reset process of the slider 33, the scraper 333 on its side slides forward along the temporary storage groove 22, scraping and pushing the debris and coolant in the temporary storage groove 22 forward to the front waste discharge hole 221, so that it falls into the filter screen frame 12 through the waste discharge hole 221. After being filtered through multiple layers of filter screens in filter frame 12, the clean coolant flows back to the storage chamber.

[0056] The operator removes the finished brake caliper from the slider 33, replaces it with a new caliper 6 to be processed, and begins the next processing cycle. When cleaning the equipment, the drawer-type filter screen frame 12 is pulled out from the housing 11, the metal debris collected by the filter is cleaned, and then the filter screen frame 12 is put back into the housing 11.
