Description

Technical Field

[0001] This utility model relates to the field of brake processing technology, and in particular to a grinding mechanism for brake processing. Background Technology

[0002] Traditional brake grinding equipment typically employs a fixed workpiece clamping structure combined with manual grinding wheel operation. Operators must use handheld power tools to grind the workpiece surface point by point, or rely on a fixed grinding wheel table to manually adjust the workpiece angle. This method has significant technical problems: uneven pressure is applied when manually controlling the contact, resulting in inconsistent grinding depth, fluctuating surface roughness, and poor adaptability to curved workpieces; at the same time, manual operation is inefficient, dust exposure harms the operator's health, and prolonged operation can easily lead to fatigue errors. These problems are particularly prominent in mass production scenarios, restricting product quality and capacity improvement.

[0003] The existing improvement solution is a guide rail-driven semi-automatic grinding mechanism: by setting a linear slide rail on the worktable, the grinding wheel device is installed on a base that can slide along the guide rail. The base is driven by a motor to move at a uniform speed. The workpiece is fixed to the worktable by a vise or pressure plate. During the grinding process, the grinding wheel is automatically fed along a predetermined trajectory to achieve mechanical contact. This technology replaces manual pushing with guide rail guidance, and the uniform speed motion driven by the motor ensures stable contact pressure between the grinding wheel and the workpiece, thereby solving the problem of uneven pressure. For example, some shaft grinding equipment adopts this structure.

[0004] Although the above technologies solve the pressure stability problem, their fixed workpiece clamping mode leads to two new defects: incompatibility with rotating workpiece machining—the flange end face commonly found in brake discs requires uniform circumferential grinding, and the fixed workpiece structure in the above technologies cannot achieve workpiece rotation, relying only on the linear movement of the grinding wheel at a single point, resulting in incomplete grinding of irregular contours and low efficiency in circumferential surface machining; inability to switch between rotating and stationary modes—when machining brake components that require stationary positioning (such as local bosses on brake caliper housings), and because the rotating grinding wheel structure in the above technologies lacks a rigid locking function, the workpiece rotating mechanism is affected by vibration during stationary grinding, causing slight oscillations and resulting in excessive positioning accuracy. The root cause lies in the structural mutual exclusion between the rotating motion mechanism and the fixed clamping function: rotating components need to retain rotational clearance, while stationary locking needs to eliminate clearance, and traditional single-mode mechanisms cannot meet the rigidity requirements of both. Utility Model Content

[0005] The purpose of this utility model is to provide a grinding mechanism for brake processing, which solves the technical contradictions of traditional translational grinding equipment, which has poor adaptability to rotary processing and insufficient rigidity for static grinding due to the single workpiece clamping mode. Specifically, it overcomes the dual defects of the fixed workpiece structure being unable to meet the requirement of uniform grinding of the brake disc circumference, and the excessive vibration caused by structural gaps in the rotating mechanism during static operation.

[0006] To achieve the above objectives, this utility model provides a grinding mechanism for brake processing, including a support platform and a sliding frame. An assembly plate is bolted to the top of the support platform, a support plate is provided on one side of the assembly plate, and a connecting plate is provided at the top of the support plate. Diagonal bracing plates are provided at the connection points of the support plate, the assembly plate, and the connecting plate to form a triangular support. A first motor is bolted to the bottom of the connecting plate, and the output end of the first motor passes through the connecting plate and connects to a rotating disk. A fixing hole is provided on the rotating disk for bolts to pass through and fix the clamp. The fixing hole can be bolted through to fix the rotating disk to the connecting plate, thereby achieving the fastening of the rotating disk.

[0007] The sliding frame has slide rails fixedly installed on both sides of its top end by bolts, and sliding blocks are slidably provided on the outer side of the slide rails. Internal threaded blocks are fixedly installed between the sliding blocks.

[0008] The internal threaded block is located inside the sliding frame and is threadedly engaged with the threaded rod. Both ends of the threaded rod are mounted on the inner wall of the sliding frame via bearings.

[0009] One end of the threaded rod extends outside the sliding frame and is connected to the output end of the second motor. The second motor is installed on the side of the sliding frame corresponding to the threaded rod by bolts.

[0010] The internal threaded block has a support plate bolted to its top, and a vertical plate is fixedly installed on one side of the top of the support plate. An inclined plate is provided on one side of the connection between the vertical plate and the support plate to form a triangular support.

[0011] The vertical plate is located above the inclined plate and a third motor is installed on one side by bolts. The output end of the third motor passes through the vertical plate and the protective cover via a shaft and is connected to the grinding wheel. The grinding wheel is rotatably located inside the protective cover. A suction connector is provided on one side of the protective cover.

[0012] This utility model discloses a grinding mechanism for brake processing, addressing the core deficiency of traditional equipment in its single workpiece processing mode. A base mounting surface is constructed by an assembly plate bolted to the top of a support platform. A support plate on one side of the assembly plate extends upwards to form a connecting plate, creating the main frame. Diagonal braces are installed at the connection nodes of the support plate, assembly plate, and connecting plate to form a triangular support structure, providing the overall frame with a rigid foundation resistant to dynamic deformation. A first motor is bolted upside down to the bottom of the connecting plate, with its output end penetrating upwards through the connecting plate to drive a rotating disk to rotate horizontally. Fixing holes on the rotating disk allow for bolting of workpiece fixtures and provide a crucial dual-mode switching capability—when an additional bolt passes through the fixing hole and locks to the connecting plate, the rotating disk transitions from a rotating state to absolute stillness, completely resolving the inherent contradiction that rotating mechanisms cannot meet the requirements of precision static grinding.

[0013] The top two sides of the independently set sliding frame are fixed with parallel slide rails by bolts. The sliding blocks slide along the slide rails to form a guide pair. An internal threaded block is fixed between the two sliding blocks. The internal threaded block and the threaded rod that runs through the sliding frame form a precision helical transmission. The two ends of the threaded rod are supported by bearings on the side wall of the sliding frame. One end extends to the outside of the frame and is directly connected to the output shaft of the second motor. The forward and reverse rotation of the motor controls the internal threaded block to drive the upper component to move forward and backward precisely. The top of the internal threaded block is vertically installed with a support plate by bolts. A vertical plate is vertically fixed on one side of the support plate, and an inclined plate is set at the connection between the two to form a triangular support against bending and torsion. A third motor is installed on the outside of the vertical plate by bolts. Its output shaft runs horizontally through the vertical plate and the protective cover to drive the internal grinding wheel to rotate at high speed. The side wall of the protective cover integrates a suction connector to connect to an external dust removal system to capture dust at the source in the grinding area.

[0014] This structure enables seamless switching between rotating and stationary processing modes: when the first motor drives the rotating disk to rotate, it adapts to the continuous grinding requirements of the brake disc end face; when the rotating disk is locked, it meets the processing requirements of high-precision static parts such as brake calipers. Multiple sets of triangular support chains (slanted braces, inclined plates) and the slide rail guide system work together to suppress the vibration caused by the centrifugal force of the workpiece rotation and the impact force of the grinding wheel. The threaded rod propulsion system ensures zero deviation of the grinding wheel feed trajectory, simultaneously achieving a triple breakthrough in expanding equipment applicability, leaping in processing accuracy, and improving the working environment.

[0023] This utility model provides a grinding mechanism for brake processing, comprising a support platform 101, on which an assembly plate 103 is bolted to the top to expand the mounting plane. A support plate 104 is vertically connected to one side of the assembly plate 103, and a connecting plate 105 is provided at the top of the support plate 104. Diagonal bracing plates 106 are respectively provided at the connection points between the support plate 104 and the assembly plate 103 and the connecting plate 105, thereby forming a stable triangular support structure, which greatly improves the deformation resistance and overall rigidity of the fixed frame. A first motor 107 is bolted to the bottom of the connecting plate 105. The output axis of the first motor 107 passes through the connecting plate 105 and is fixedly connected to the center of the rotating disk 108. The fixing hole 109 opened on the rotating disk 108 allows bolts to pass through to fix the clamp.Crucially, the fixing hole 109 can also be further penetrated by bolts and locked to the connecting plate 105, giving the rotating disk 108 a lockable dual-mode function; the sliding frame 102 is independently located on one side of the support platform 101, and two slide rails 111 are fixed parallel to each other on both sides of its top end by bolts. Each slide rail 111 is slidably fitted with a sliding block 112, and an internal threaded block 113 is horizontally fixed between the two sliding blocks 112; the internal threaded block 113 is located in the internal cavity of the sliding frame 102 and forms a precise threaded engagement with the horizontally arranged threaded rod 114; the two ends of the threaded rod 114 are respectively The bearing supports the sliding frame 102 on its side wall to reduce friction. One end of the bearing extends to the outside of the sliding frame 102 and is directly connected to the output end of the second motor 115, which is bolted to the outer wall of the sliding frame 102. A support plate 116 is vertically mounted on the top of the internal thread block 113 by bolts. A vertical plate 117 is fixed to one side of the top of the support plate 116, and an inclined plate 118 is set on one side of the connection between the vertical plate 117 and the support plate 116 to form a key triangular support, which greatly enhances the bending and torsional resistance of the base of the vertical plate 117. The area above the vertical plate 117 near the inclined plate 118 is bolted to... A third motor 119 is installed, the output end of which passes through the vertical plate 117 and the side wall of the protective cover 120 via a shaft, driving the grinding wheel 121 inside the protective cover 120 to rotate at high speed. The protective cover 120 detachably seals and covers the working area of ​​the grinding wheel 121, and a suction connector 122 on one side is used to connect to an external negative pressure system to capture grinding dust. The support platform 101, assembly plate 103, support plate 104, connecting plate 105, and diagonal brace 106 constitute an anti-torsional frame. The rotating disk 108 and its dual-mode locking structure provide rotation / The stationary workpiece is clamped; the sliding frame 102, slide rail 111, and sliding block 112 constitute a precision guiding system; the threaded rod 114 and the internal threaded block 113 are converted into linear feed under the drive of the second motor 115; the support plate 116, vertical plate 117, and inclined plate 118 form a vibration-resistant grinding head support; the third motor 119 drives the grinding wheel 121 to rotate via the shaft; the protective cover 120 and the suction connector 122 complete the dust sealing control; this integrated structure, through multiple triangular supports and threaded guide design, ensures high stability and positioning accuracy during the rotational or stationary grinding of brake parts.

[0024] Working principle: The operator first places the brake workpiece to be ground on the rotating disk 108, and uses bolts through the fixing hole 109 and a clamp to firmly hold and fix the workpiece. The fixing hole 109 can also be bolted through and locked to the connecting plate 105. When the first motor 107 is started, its output drives the rotating disk 108 and the workpiece to rotate at a constant speed around the axis, providing rotational grinding for brake disc workpieces. When the fixing hole 109 is locked to the connecting plate 105 by bolts, the rotating disk 108 remains stationary, which can meet the needs of workpieces that require fixed posture grinding. The frame structure formed by the support plate 104, the assembly plate 103 and the connecting plate 105, together with the diagonal brace 106 set at the connection, forms a triangular support, which effectively enhances the overall rigidity of the workpiece rotation / stationary system. Stability is ensured to prevent vibration and offset during processing, guaranteeing the accuracy of the processing datum. Simultaneously, the second motor 115 drives the threaded rod 114 to rotate. Since the internal threaded block 113 and the threaded rod 114 form a threaded engagement, the rotation of the threaded rod 114 is converted into linear motion of the internal threaded block 113 along its axial direction. The movement of the internal threaded block 113 drives the support plate 116, bolted to its top, to move synchronously. The sliding blocks 112 on both sides of the support plate 116 slide on the slide rail 111 fixed to the top of the sliding frame 102, providing precise guidance and stable support for the movement of the internal threaded block 113 and the support plate 116, effectively overcoming lateral forces, ensuring the straightness of the movement trajectory, and improving feed accuracy. The vertical plate 117 fixedly installed at the top of the support plate 116 and its… The inclined plate 118 at the connection point forms a triangular support structure, significantly improving the bending and torsional stiffness of the vertical plate 117 and its components, providing a solid support foundation for the grinding operation. When the support plate 116 moves the vertical plate 117 to the required grinding position, the third motor 119 mounted on the vertical plate 117 is activated. The output end of the third motor 119 passes through the shaft of the vertical plate 117 and the protective cover 120, driving the grinding wheel 121 located inside the protective cover 120 to rotate at high speed. The high-speed rotating grinding wheel 121 grinds specific surfaces of the brake workpiece whether the workpiece is rotating or stationary. The protective cover 120 effectively encloses the grinding area, and the suction connector 122 on its side can be connected to external dust removal equipment to suction the dust generated during grinding in real time. The reduction of dust and debris significantly improves the working environment, ensures the health and safety of operators, and reduces the impact of dust on equipment precision. The entire process is controlled by the first motor 107 to control the workpiece's motion (rotation / stationary), the second motor 115 to control the grinding wheel's feed position, and the third motor 119 to control the grinding wheel's rotation. The three axes work together to achieve efficient, stable, and controllable automated grinding of workpieces with different brake structures. The overall structure, through multiple triangular supports (diagonal brace 106, inclined plate 118) and guide rail 111, ensures the system's high rigidity and smooth movement under dynamic loads. The dual-mode free switching design significantly broadens the processing adaptability, ultimately achieving the technical effect of improving grinding precision, surface quality, processing efficiency, and process flexibility.
