Description

Technical Field

[0001] This invention relates to the field of milling technology, and more particularly to a disc brake seat machining device. Background Technology

[0002] Disc brake systems are widely used in bicycles, motorcycles, cars, and even semi-trailers due to their excellent braking performance. As a key component of the disc brake system, the quality and precision of the disc brake mount directly affect the reliability and safety of the entire braking system. With the continuous development of the transportation industry, the requirements for the quality and performance of disc brake mounts are becoming increasingly stringent. They not only need to possess high strength and high wear resistance, but also ensure dimensional accuracy and surface quality to meet the demands of complex and ever-changing braking conditions.

[0003] Traditional disc brake mount manufacturing typically employs a step-by-step process, where die casting, milling, and finishing are performed sequentially on different equipment. This method has several drawbacks: firstly, transferring the workpiece between different machines consumes significant time and manpower, leading to low production efficiency; secondly, repeated clamping and positioning can easily cause cumulative errors and deformations in the workpiece, affecting its machining accuracy and consistency. Furthermore, during processing, metal shavings and cutting fluid splashes not only pollute the machining environment but can also damage equipment and other components, increasing production costs and maintenance complexity.

[0004] Therefore, a disc brake seat processing device is proposed to solve the problem of workpiece deformation caused by frequent clamping. Summary of the Invention

[0005] The purpose of this invention is to solve the problem of workpiece deformation caused by frequent clamping in existing disc brake seat processing equipment, and to propose a disc brake seat processing device.

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

[0007] A disc brake seat processing device includes a base, on which an annular guide rail is provided, and a plurality of lower mold seats are slidably disposed within the annular guide rail;

[0008] The base is equipped with a die-casting assembly, a milling assembly, and a finishing assembly located on the rotation path of the lower mold base; thus, the disc brake seat completes the entire process from die-casting to preliminary processing and then to fine processing in sequence;

[0009] The milling assembly includes a second bracket, which is located on both sides of the annular guide rail. A second cylinder is fixed to the top of the second bracket, and a support plate is fixed to the output end of the second cylinder facing the annular guide rail. A mounting plate is slidably connected below the support plate, and a milling cutter support seat is fixed to one side of the mounting plate. A milling cutter is installed below the milling cutter support seat for rough machining of the die-cast disc brake seat.

[0010] A cylinder three is connected to the other side of the mounting plate. A sliding groove one is opened on the side of the bracket two near the cylinder three. A sliding block two is slidably connected in the sliding groove one. A cylinder three is fixed on the side of the sliding block two away from the mounting plate. The output end of the cylinder three passes through the sliding block two and is connected to the mounting plate.

[0011] A limiting plate is provided below the mounting plate. The outer wall of the limiting plate is slidably connected to the inner wall of the bracket. A sliding groove is longitudinally provided on the bracket. A sliding wheel is slidably connected in the sliding groove and is fixed to the outer wall of the limiting plate.

[0012] Preferably, a sealing ring is provided below the sliding path of the limiting plate. The outer wall of the sealing ring is fixed to the inner wall of the bracket. An annular groove is provided at the top of the sealing ring. A cylinder is fixed at the bottom of the annular groove. A sliding ring is fixed at the output end of the cylinder.

[0013] Preferably, a limiting groove is formed through the center of the limiting plate, and the two ends of the limiting groove are reserved with a space equivalent to the radius of the milling cutter. This design can effectively prevent the milling cutter from hitting the bracket two during movement and limit the position of the milling cutter.

[0014] Preferably, the die-casting assembly includes a bracket, which is located on both sides of the annular guide rail. A cylinder is fixed to the top of the bracket, and an upper mold base is fixed to the output end of the cylinder facing the annular guide rail. The upper mold base is adapted to the lower mold base and located on its sliding path.

[0015] The bracket has four sliding grooves on both sides of its sidewalls. The four sliding grooves are located between the upper mold base and the lower mold base. A sliding wheel is slidably connected in the four sliding grooves. The sliding wheel is fixed to the sidewall of the upper mold base by a connecting rod.

[0016] Preferably, a sealing ring three is slidably connected to the outer wall of the upper mold base. The end of the sealing ring three facing the annular guide rail is in clearance fit with the top of the lower mold base. The outer wall of the sealing ring three is fixed to the bracket. A liquid passage hole is opened through the outer wall of the sealing ring three through the bracket. The liquid passage hole is used to introduce molten metal for disc brake seat processing, so that the molten metal is accurately injected into the cavity formed by the upper mold base and the lower mold base.

[0017] Preferably, the finishing component includes a bracket three, which is located on both sides of the annular guide rail. A cylinder five is fixed to the top of the bracket three, and a clamping seat is fixed to the output end of the cylinder five facing the annular guide rail. The clamping seat is used to clamp the finishing tool, and the finishing tool is used to finish the disc brake seat.

[0018] The outer wall of the bracket three is provided with a sliding groove three, and a sliding wheel three is slidably connected in the sliding groove three, and the sliding wheel three is fixed to the clamping seat.

[0019] Preferably, a second sealing ring is provided below the sliding path of the finishing tool. The second sealing ring has the same structure as the first sealing ring. The second sealing ring extends out and contacts the bottom of the clamping seat. At the same time, the second sealing ring fits against the lower mold base to form a sealed environment.

[0020] Preferably, the inner walls of the sealing ring one and the sealing ring two are respectively opened through the bracket two and the bracket three. One channel is used to introduce cutting fluid to provide cooling and lubrication for the finishing tool during the finishing process, so as to ensure the machining accuracy and tool life. The other channel is used to draw in waste liquid and small particles through an air pump.

[0021] Preferably, a sliding block is fixed at the bottom of the lower mold base, the sliding block slides within the annular guide rail, an installation groove is provided inside the lower mold base, a plurality of cylinders are fixed at the bottom of the installation groove, a fixing plate is fixed at the output end of the cylinders, a positioning rod is fixed above the fixing plate, and the positioning rod passes through the top of the lower mold base.

[0022] Preferably, 4-6 cylinders are evenly distributed on the mounting plate to improve the stability of the moving mounting plate.

[0023] The beneficial effects of this invention are:

[0024] The device does not use any clamps. By setting a positioning rod, its position and size are perfectly matched with the positioning holes required for the disc brake seat during processing, ensuring the precise positioning of the disc brake seat during processing. At the same time, the sealing ring and the lower mold base form a sealed environment, avoiding errors caused by external factors during processing, effectively improving the dimensional accuracy and surface quality of the disc brake seat, and ensuring product consistency and stability.

[0025] This disc brake seat machining device adopts a ring guide rail design, integrating the die-casting, milling, and finishing components into one unit. The lower mold base passes sequentially through each machining component along the ring guide rail, enabling continuous processing of the disc brake seat from die-casting to preliminary machining and then to fine machining. This eliminates the need to transfer workpieces between different devices, reducing the number of clamping and positioning operations, shortening the production cycle, and minimizing the chance of cumulative errors and deformation in the workpiece.

Detailed Implementation

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Reference Figures 1-9 A disc brake seat processing device includes a base 1, on which an annular guide rail 101 is provided. A plurality of lower mold seats 102 are slidably arranged in the annular guide rail 101, and the plurality of lower mold seats 102 are used to receive molten metal for disc brake seat processing.

[0038] The base 1 is provided with a die-casting component 2, a milling component 3 and a finishing component 4 located on the rotation path of the lower mold base 102, which sequentially complete the entire process of the disc brake seat from die-casting to preliminary processing and then to fine processing.

[0039] The die-casting assembly 2 includes a bracket 201 located on both sides of the annular guide rail 101. A cylinder 202 is fixed to the top of the bracket 201. An upper mold base 203 is fixed to the output end of the cylinder 202 facing the annular guide rail 101. The upper mold base 203 is adapted to the lower mold base 102 and located on its sliding path. When the cylinder 202 drives the upper mold base 203 to move downward, it can cooperate with the lower mold base 102 to complete the die-casting action.

[0040] The bracket 201 has sliding grooves 204 on both side walls. The sliding grooves 204 are located between the upper mold base 203 and the lower mold base 102. A sliding wheel 205 is slidably connected in the sliding grooves 204. The sliding wheel 205 is fixed to the side wall of the upper mold base 203 by a connecting rod to ensure that the upper mold base 203 moves stably in the vertical direction, avoids deviation during the die casting process, and ensures the quality of die casting.

[0041] Furthermore, a sealing ring 206 is slidably connected to the outer wall of the upper mold base 203. The end of the sealing ring 206 facing the annular guide rail 101 is clearance-fitted with the top of the lower mold base 102. The outer wall of the sealing ring 206 is fixed to the bracket 201. A liquid passage hole 2061 is opened through the bracket 201 on the outer wall of the sealing ring 206. The liquid passage hole 2061 is used to introduce molten metal for disc brake seat processing, so that the molten metal is accurately injected into the cavity formed by the upper mold base 203 and the lower mold base 102.

[0042] When the lower mold base 102 moves directly below the die-casting assembly 2, the bottom of the sealing ring 206 forms a seal with the top of the lower mold base 102. At this time, molten metal is injected into the cavity through the liquid passage 2061, and the cylinder 202 drives the upper mold base 203 to move downward, tightly engaging with the lower mold base 102, completing the die-casting of the disc brake seat in a sealed environment. After die-casting is completed, the lower mold base 102 continues to move along the annular guide rail 101, passing sequentially through the milling assembly 3 and the finishing assembly 4 for subsequent processing.

[0043] The milling assembly 3 includes a second bracket 301 located on both sides of the annular guide rail 101. A second cylinder 302 is fixed to the top of the second bracket 301. A support plate 303 is fixed to the output end of the second cylinder 302 facing the annular guide rail 101. A mounting plate 304 is slidably connected below the support plate 303. A milling cutter support seat 305 is fixed to one side of the mounting plate 304. A milling cutter 3051 is installed below the milling cutter support seat 305. The milling cutter 3051 is used for rough machining of the die-cast disc brake seat.

[0044] A cylinder 306 is connected to the other side of the mounting plate 304. The cylinder 306 drives the mounting plate 304 to move laterally through its extension and retraction, thereby adjusting the position of the milling cutter 3051 in the horizontal direction to meet the needs of different machining positions.

[0045] The bracket 2 301 has a sliding groove 3061 on the side near the cylinder 306. A sliding block 2 3062 is slidably connected in the sliding groove 3061. The cylinder 306 is fixed on the side of the sliding block 2 3062 away from the mounting plate 304. The output end of the cylinder 306 passes through the sliding block 2 3062 and is connected to the mounting plate 304.

[0046] A limiting plate 307 is provided below the mounting plate 304. The outer wall of the limiting plate 307 is slidably connected to the inner wall of the bracket 301. A sliding groove 309 is longitudinally provided on the bracket 301. A sliding wheel 310 is slidably connected in the sliding groove 309. The sliding wheel 310 is fixed to the outer wall of the limiting plate 307. Through the cooperation of the sliding groove 309 and the sliding wheel 310, the limiting plate 307 can move stably up and down in the bracket 301, providing a basis for subsequent sealing and limiting operations.

[0047] When it is necessary to mill the surface of the primary workpiece after die casting, the lower mold base 102 containing the primary workpiece is rotated by starting the annular guide rail 101. When it rotates to the position of the milling component 3, the annular guide rail 101 is closed.

[0048] When cylinder 4 313 is started, its output end drives the sliding ring 314 to extend and contact the bottom of the limiting plate 307. At this time, the sealing ring 311 fits against the lower mold base 102 to form a sealed environment and prevent the flying of chips generated during the milling process.

[0049] A sealing ring 311 is provided below the sliding path of the limiting plate 307. The outer wall of the sealing ring 311 is fixed to the inner wall of the bracket 301. An annular groove 312 is provided at the top of the sealing ring 311. A cylinder 313 is fixed at the bottom of the annular groove 312. A sliding ring 314 is fixed at the output end of the cylinder 313.

[0050] During processing, the sliding ring 314 is driven by cylinder 313 to extend and contact the bottom of the limiting plate 307. At the same time, the sealing ring 311 fits against the lower mold base 102 to form a sealed environment, preventing the flying of chips generated during milling and ensuring a clean and safe processing environment.

[0051] The center of the limiting plate 307 has a limiting groove 308. Both ends of the limiting groove 308 have a space equivalent to the radius of the milling cutter 3051. This design can effectively prevent the milling cutter 3051 from hitting the bracket 301 during movement, and play a precise limiting role in the position of the milling cutter 3051, ensuring the safety and stability of the machining process.

[0052] The finishing component 4 includes a bracket 3 401, which is located on both sides of the annular guide rail 101. A cylinder 5 402 is fixed on the top of the bracket 3 401. A clamping seat 403 is fixed to the output end of the cylinder 5 402 facing the annular guide rail 101. The clamping seat 403 is used to clamp the finishing tool 404, which is used to finish the disc brake seat.

[0053] The outer wall of the bracket 401 is provided with a sliding groove 405, and a sliding wheel 406 is slidably connected in the sliding groove 405. The sliding wheel 406 is fixed to the clamping seat 403.

[0054] A second sealing ring 407 is provided below the sliding path of the finishing tool 404. The second sealing ring 407 has the same structure as the first sealing ring 311. The second sealing ring 407 extends out and contacts the bottom of the clamping seat 403. At the same time, the second sealing ring 407 fits against the lower die seat 102 to form a sealed environment, preventing the splashing of tiny particles and cutting fluid generated during the finishing process, keeping the machining area clean, reducing contamination to equipment and other components, and also helping to improve machining quality.

[0055] When the lower mold base 102 moves directly below the finishing component 4, cylinder 5 402 drives the clamping seat 403 to move downwards, bringing the finishing tool 404 closer to the disc brake seat, and performing finishing on the disc brake seat in a sealed environment. After the machining is completed, the lower mold base 102 continues to move along the annular guide rail 101 to complete the entire machining process of the disc brake seat.

[0056] Furthermore, the inner walls of the sealing ring 311 and the sealing ring 407 respectively have two channels penetrating the bracket 301 and the bracket 401. One channel is used to introduce cutting fluid to provide cooling and lubrication for the finishing tool 404 during the finishing process, ensuring machining accuracy and tool life. The other channel uses an air pump to draw in waste liquid and small particles, promptly discharging the waste liquid and small particles generated during machining from the sealed environment, further improving the cleanliness of the machining area.

[0057] Furthermore, a sliding block 1021 is rotatably connected to the bottom of the lower mold base 102 via a rotary drive. The sliding block 1021 slides within the annular guide rail 101. An installation groove 1022 is provided inside the lower mold base 102. Several cylinders 1023 are fixed at the bottom of the installation groove 1022. A fixing plate 1024 is fixed at the output end of each cylinder 1023. A positioning rod 1025 is fixed above the fixing plate 1024. The positioning rod 1025 passes through the top of the lower mold base 102, and its position and size are perfectly matched with the positioning holes required for the disc brake seat during processing, so as to ensure the precise position of the disc brake seat during processing.

[0058] Furthermore, a robotic arm 5 is fixed on the base 1. The main function of the robotic arm 5 is to clamp the lower mold base 102, remove the disc brake seat, which has been die-cast by the die-casting assembly 2 and is still at a high temperature, from the die-casting position, and accurately place it into the cooling device for cooling treatment. After the disc brake seat has cooled to a suitable temperature, the robotic arm 5 will clamp it again and place it back into the designated position on the annular guide rail 101 for subsequent milling operations, thereby completing the complete processing flow of the disc brake seat.

[0059] Furthermore, preferably 4-6 cylinders 306 are evenly distributed on the mounting plate 304 to improve the stability of the movement of the mounting plate 304.

[0060] Working principle: When the disc brake seat needs to be processed, the lower mold base 102 is rotated by starting the annular guide rail 101. When the lower mold base 102 rotates to the position of the die casting component 2, the annular guide rail 101 is closed and the lower mold base 102 comes to a stop.

[0061] At this time, the top edge of the lower mold base 102 contacts the sealing ring 206. By starting the cylinder 202, its output end drives the upper mold base 203 to move downward. When the bottom surface of the upper mold base 203 is inside the sealing ring 206 and above the liquid passage hole 2061, the cylinder 202 stops.

[0062] Molten metal for disc brake seat processing is injected into the cavity formed by the upper mold base 203 and the lower mold base 102 through the liquid passage 2061.

[0063] again start up Cylinder 202, with its output end driving the upper mold base 203 to move downwards, tightly engaging with the lower mold base 102, applies pressure to the molten metal inside the cavity in a sealed environment, completing the die-casting of the disc brake seat. At this time, the disc brake seat is in a high-temperature die-casting state, with its shape initially determined but its surface relatively rough.

[0064] After die casting is completed, the robotic arm 5 is activated, clamping the lower mold base 102 and the disc brake seat inside it, which has been die-cast and is still in a high temperature state, and placing it into an external cooling device for cooling. The robotic arm 5 is activated again, and clamps the cooled disc brake seat and the lower mold base 102, and places them back into the designated position on the annular guide rail 101. At this time, the lower mold base 102 continues to slide along the annular guide rail 101, ready to enter the milling process.

[0065] When the milling assembly 3 is rotated to its position, the annular guide rail 101 is closed.

[0066] When cylinder 4 313 is started, its output end drives the sliding ring 314 to extend and contact the bottom of the limiting plate 307. At this time, the sealing ring 311 fits against the lower mold base 102 to form a sealed environment and prevent the flying of chips generated during the milling process.

[0067] By activating cylinder 302, its output end drives the support plate 303 to move downward, which in turn drives the mounting plate 304, the milling cutter support 305, and the milling cutter 3051 to move downward toward the disc brake seat.

[0068] By activating cylinder six 1023, the fixed plate 1024 and the positioning rod 1025 are driven to slide downward, preventing the positioning rod 1025 from colliding with the milling cutter 3051 during the milling process.

[0069] The cylinder 306 is activated, and its extension and retraction motion drives the mounting plate 304 to move laterally, adjusting the position of the milling cutter 3051 in the horizontal direction to meet the needs of different machining positions. The limiting groove 308, which runs through the center of the limiting plate 307, has space reserved at both ends that is equivalent to the radius of the milling cutter 3051, which plays a precise limiting role in the position of the milling cutter 3051.

[0070] After adjusting the position of the milling cutter 3051, the milling cutter 3051 is started to perform surface milling on the die-cast disc brake seat, so that the shape and size of the disc brake seat are closer to the final requirements. During the milling process, the upper surface of the disc brake seat is milled evenly by rotating the lower mold base 102.

[0071] After milling is completed, the annular guide rail 101 is activated to slide the lower mold base 102 to the position of the finishing component 4. The second sealing ring 407 extends out and contacts the bottom of the clamping seat 403. At the same time, the second sealing ring 407 fits against the lower mold base 102 to form a sealed environment.

[0072] The cylinder 1023 is activated, and its output drives the clamping seat 403 to move downwards, bringing the finishing tool 404 closer to the disc brake seat. In a sealed environment, the finishing tool 404 aligns with the positioning rod 1025 to perform finishing on the through-hole of the disc brake seat, further improving the dimensional accuracy and surface quality of the disc brake seat. During the feeding process of the finishing tool 404, the fixing plate 1024 and the positioning rod 1025 slide downwards, preventing the disc brake seat from shifting while also preventing the positioning rod 1025 from colliding with the finishing tool 404.

[0073] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
