Description

Technical Field

[0001] This utility model relates to the technical field of grinding devices, specifically a surface grinding device for brake disc production. Background Technology

[0002] During use, brake discs may become uneven or bumpy due to friction and wear, which can affect the vehicle's braking performance and driving safety. Regularly grinding the brake discs can remove the uneven parts on the surface and restore their original flatness, thereby improving the vehicle's braking effect and driving safety. Grinding the brake discs can also remove surface corrosion and deposits, reduce wear caused by foreign objects or corrosion, and thus extend their service life.

[0003] For example, the disc brake disc surface polishing and grinding device disclosed in the authorization announcement number CN219542685U includes a worktable, a support frame, a control component, a grinding wheel, a support ring, and a clamping component; an adjustment component is installed at the output end of the clamping component, and the output end of the adjustment component abuts against the outer wall of the disc brake disc; a limit group is also fixedly installed on the worktable.

[0004] Although it features an adjustment component that can adjust the contact position with the disc brake disc, allowing for flexible adjustment based on the disc brake disc's thickness, preventing the adjustment component's output from interfering with the grinding wheel, it uses a limit cylinder to move the limit rod and limit plate downwards to press against the disc brake disc. This, combined with a support ring, keeps the disc brake disc level. The clamping component then clamps it, effectively ensuring the disc brake disc's horizontal position and preventing tilting. A handle on the limit plate facilitates easy removal, and the position of the screw can be adjusted by rotating it on the screw sleeve, preventing interference between the screw and the grinding wheel.

[0005] However, this does not solve the problem that existing grinding devices of this type are generally not conducive to the simultaneous operation of multiple grinding heads, are not convenient for center positioning and clamping of the brake disc, and are not convenient for multi-stage rotation of the rotating disc for grinding, which greatly affects the grinding range and the convenience of multi-stage rotation of the grinding device for grinding the rotating disc. Utility Model Content

[0006] The purpose of this utility model is to provide a surface grinding device for brake disc production, so as to solve the problems mentioned in the background art, such as the inconvenience of multiple grinding heads working simultaneously for grinding, the inconvenience of center positioning and clamping the brake disc, and the inconvenience of multi-stage rotation for grinding the rotating disc, which affect the grinding range and the convenience of multi-stage rotation of the grinding device for grinding the rotating disc.

[0007] To address the technical problems mentioned in the background section, some embodiments of this application provide a surface grinding device for brake disc production, including a support frame and a U-shaped frame. The U-shaped frame is externally mounted on the support frame, and a rotating disk is externally mounted on the U-shaped frame. A connecting plate is mounted on the side wall of the support frame, and an L-shaped plate is externally mounted on the connecting plate. An electric push rod is mounted on the side wall of the connecting plate, and the output end of the electric push rod is connected to the L-shaped plate. A servo motor is mounted on the top of the L-shaped plate, and two sets of synchronous pulley assemblies are externally mounted on the L-shaped plate. The output end of the servo motor is connected to the synchronous pulley assemblies. Support columns are symmetrically mounted on the bottom of the L-shaped plate, and rotating columns are movably mounted inside each support column. The rotating columns extend through the support columns and the L-shaped plate to their exterior. The ends of the synchronous pulley assemblies furthest from the servo motor are all connected to the rotating columns.

[0008] Furthermore, a grinding head body is installed at the bottom of each of the rotating columns, and four sets of equally spaced sliders are installed on the side wall of the L-shaped plate.

[0009] Furthermore, guide rails are symmetrically installed on the side wall of the support frame below the connecting plate, and the slider is slidably connected to the guide rails.

[0010] Furthermore, four sets of stepper motors with equal spacing are installed on the side wall of the rotating disk. The output end of each stepper motor is equipped with a threaded rod, which extends into the interior of the rotating disk and is movably connected to it.

[0011] Furthermore, threaded blocks are fitted onto the surface of the threaded rod, the threaded rod is threadedly connected to the threaded blocks, a clamp is installed at the top of each threaded block, and a power motor is installed on the side wall of the U-shaped frame.

[0012] Furthermore, a rotating shaft is installed at the output end of the power motor, the rotating shaft extends through the U-shaped frame to its outside, a second small gear is fitted on the surface of the rotating shaft inside the U-shaped frame, and support seats are symmetrically installed at the top of the U-shaped frame.

[0013] Furthermore, each of the support bases has an auxiliary shaft movably installed inside, and the auxiliary shafts extend to the outside of the support base, with a set of auxiliary shafts having a sector gear fitted on their surface.

[0014] Furthermore, the sector gear meshes with the second pinion, a support block is provided inside the U-shaped frame, the support block is connected to the auxiliary shaft, and a variable frequency motor is installed on the side wall of the support block.

[0015] Furthermore, a first pinion is installed at the output end of the variable frequency motor, and a rotating shaft is movably installed at the center of the support block, extending to the outside of the support block.

[0016] Furthermore, a first large gear is fitted onto the surface of the external rotating shaft of the support block, and the first small gear meshes with the first large gear. The side of the rotating shaft away from the support block is connected to the rotating disk.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the grinding device not only realizes that multiple grinding heads of the grinding device can work simultaneously to grind, which facilitates the center positioning and clamping of the brake disc, but also facilitates multi-stage rotation to grind the rotating disc, increases the grinding range, and improves the convenience of multi-stage rotation of the grinding device to grind the rotating disc.

[0018] An electric push rod drives an L-shaped plate to move up and down. The L-shaped plate then moves the support column, rotating column, and grinding head body up and down to the surface of the brake disc. A servo motor drives two sets of synchronous pulley assemblies to rotate. Supported by the support column, the two sets of synchronous pulley assemblies drive two sets of rotating columns to rotate. The two sets of rotating columns drive two sets of grinding head bodies to rotate, which facilitates the simultaneous operation of multiple grinding heads. This improves the efficiency of the grinding device in grinding the brake disc.

[0019] Four stepper motors are turned on, driving the threaded rod to rotate. The threaded rod drives the threaded block to rotate, and the threaded block drives the clamping plate to move in opposite directions, thus centering and clamping the brake disc. This facilitates convenient centering and clamping of the brake disc, improving the ease of centering and clamping of the brake disc by the grinding device.

[0020] The power motor drives the rotating shaft to rotate, which in turn drives the second pinion to rotate. The second pinion drives the sector gear to rotate, which in turn drives the auxiliary shaft, support block, rotating disk, and brake disk to rotate at a certain angle. The frequency converter motor drives the first pinion to rotate, which in turn drives the first large gear to rotate. The first large gear drives the rotating shaft, rotating disk, and brake disk to rotate. This enables the grinding device to perform convenient multi-stage rotation grinding on the rotating disk, increasing the grinding range and improving the convenience of multi-stage rotation grinding on the rotating disk.
