Description

Technical Field

[0001] This invention relates to the field of disc brake pad production technology, specifically to a grinding and rust removal device for disc brake pad production. Background Technology

[0002] Disc brakes consist of a brake disc connected to the wheel and brake calipers on the edge of the disc. When braking, high-pressure brake fluid pushes the brake pads to clamp the brake disc, thus producing a braking effect. They use metal discs instead of drums. There are flat brake shoes on both sides of the brake disc. When the oil pressure from the master cylinder is sent to the slave cylinder, the brake shoes clamp onto the brake disc to achieve a braking effect. They are now commonly used on the front wheels, and some high-end cars are equipped with four-wheel disc brakes. Their advantages are that they are sensitive, have good heat dissipation, do not require adjustment of brake clearance, and are easy to maintain.

[0003] During the production of disc brake pads, the surface needs to be polished and rust removed. However, the shape of disc brake pads is not a common regular shape. Existing polishing equipment cannot quickly fix the disc brake pads in place during the polishing process, and the disc brake pads may shift during polishing, affecting the polishing effect. In addition, there are some gaps and holes on the surface of the disc brake pads, and the polishing pads cannot clean these gaps completely during polishing. In order to solve the above problems, we propose a polishing and rust removal device for disc brake pad production. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a grinding and rust removal device for disc brake pad production, comprising a base, a housing fixedly connected to the top of the base, a telescopic rod fixedly installed at the top of the inner cavity of the housing, a connecting plate fixedly connected to the bottom of the telescopic rod, a motor fixedly installed on the top side of the connecting plate away from the telescopic rod, the output end of the motor passing through the connecting plate and fixedly connected to a grinding device, a circular plate fixedly connected to the center of the top of the base, the circular plate being directly below the grinding device, a support column fixedly connected to the top of the circular plate, a clamping plate fixedly connected to the top of the support column, a collection port opened at the top of the circular plate, a filter fixedly connected to the top of the inner cavity of the base, the filter being directly below the collection port, the disc brake pad being clamped by the clamping plate, and after the disc brake pad is fixed, the surface of the disc brake pad is ground, thus cleaning the surface of the disc brake pad using this device.

[0005] Preferably, the clamping plate includes a clamping seat, a crossbar is fixedly connected to the center of the bottom of the clamping seat, a sliding block is slidably connected to the outer surface of the crossbar, a clamping head is fixedly connected to the top of the sliding block, an inclined block is slidably connected to the outer surface of the sliding block, and the outer surface of the inclined block is slidably connected to the inner surface of the clamping seat. An electromagnet is fixedly connected to the inner surface of the clamping seat. The disc brake pad is fixed by the clamping plate, so that the disc brake pad is firmly fixed.

[0006] Preferably, the clamping head includes a fixing plate, which is fixedly connected to the top of the sliding block. An arc-shaped plate is rotatably connected to the side of the fixing plate away from the sliding block, and a straight plate is fixedly connected to the bottom of the arc-shaped plate. The clamping head can fix irregular disc brake pads and fix disc brake pads of various specifications.

[0007] Preferably, the filter includes a cuboid, the top of which is fixedly connected to the top of the inner cavity of the base, a guide plate is fixedly connected to the top of the cuboid, a straight column is fixedly connected to the bottom of the guide plate, and a diverter plate is fixedly connected to the bottom of the straight column, so that the filter filters the water flow.

[0008] Preferably, a corrugated screen plate is fixedly connected to the bottom of the cube, and a filter hole is provided on the top of the corrugated screen plate, which makes the filter less likely to be clogged by dirt.

[0009] Preferably, the polishing device includes a vertical column, a cylinder slidably connected to the inner surface of the vertical column, a polishing disc fixedly connected to the outer surface of the cylinder, a movable column fixedly connected to the top of the inner cavity of the cylinder, and the bottom of the movable column slidably connected to the bottom of the cylinder. The polishing device can polish the gaps of the disc brake pads.

[0010] Preferably, a column is fixedly connected to the top of the cylinder, a horizontal plate is fixedly connected to the outer surface of the column, an elastic plate is slidably connected to the top of the horizontal plate, and the outer surface of the elastic plate is fixedly connected to the inner surface of the vertical column. The horizontal plate and the elastic plate work together to protect the disc brake pads.

[0011] Preferably, the movable column includes a cylinder, a spring is fixedly connected to the top of the inner cavity of the cylinder, a sliding column is fixedly connected to the bottom end of the spring, a stop is fixedly connected to the outer surface of the sliding column, and the outer surface of the stop is slidably connected to the bottom of the cylinder. The movable column can apply rust remover to the surface of the disc brake pad during the polishing process.

[0012] This invention provides a grinding and rust removal device for disc brake pad production. It has the following beneficial effects: 1. The grinding and rust removal device for disc brake pad production uses an inclined block to squeeze the sliding block, causing the clamping head to move inward under force. By rotating, the surface of the arc plate and the surface of the disc brake pad can come into contact with each other. The arc plate clamps the disc brake pad under force, and the disc brake pad is fixed in place. The straight plate can prevent the disc brake pad from moving downward under force during the grinding process.

[0013] II. The grinding and rust removal device for disc brake pad production grinds and removes rust from the surface of the disc brake pad. The motor drives the grinding device to grind the surface of the disc brake pad. During the grinding process, the bottom of the grinding pad contacts the surface of the disc brake pad, and the movable column moves upward under force. The rust removal liquid inside the cylinder flows out, so that the grinding device does not require manual application of rust removal liquid during the grinding process. Moreover, when the movable column encounters a gap, it can hold against the bottom of the gap and grind the gap.

[0014] 3. The grinding and rust removal device used in the production of disc brake pads protects the disc brake pads through a horizontal plate and an elastic plate. During the grinding process, if the grinding pad is subjected to excessive force, the disc brake pad may be damaged due to excessive force. The outer surfaces of the horizontal plate and the elastic plate are in contact with each other. When the grinding pad is pressed down, the elastic plate begins to bend due to the force from the horizontal plate. When the elastic plate bends to a certain extent, the horizontal plate slides over the surface of the elastic plate and no longer contacts the lower surface of the elastic plate. The grinding pad is no longer subjected to force and stops friction with the surface of the disc brake pad.

[0015] IV. The grinding and rust removal device used in the production of disc brake pads filters the water flow through a filter. After grinding, the water flow washes away the stains on the surface of the disc brake pads. The water flow enters the filter through the collection port. The shape of the corrugated screen plate allows the stains that are filtered out after the water flow passes through the screen plate to slide to the bottom of the corrugated screen plate, which facilitates the collection of stains and makes it less likely for the screen plate to be blocked by stains.

The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] Example 1: As Figures 1-4 As shown, the present invention provides a technical solution: a grinding and rust removal device for disc brake pad production, comprising a base 1, a housing 2 fixedly connected to the top of the base 1, a telescopic rod 3 fixedly installed on the top of the inner cavity of the housing 2, a connecting plate 4 fixedly connected to the bottom of the telescopic rod 3, a motor 5 fixedly installed on the top side of the connecting plate 4 away from the telescopic rod 3, the output end of the motor 5 passing through the connecting plate 4 and fixedly connected to a grinding device 6, and a circular plate 7 fixedly connected to the center of the top of the base 1, the circular plate 7 being located directly below the grinding device 6, the top of the circular plate 7 being fixedly... A support column 8 is fixedly connected, and a clamping plate 9 is fixedly connected to the top of the support column 8. A collection port 10 is opened on the top of the circular plate 7. A filter 11 is fixedly connected to the top of the inner cavity of the base 1. The filter 11 is located directly below the collection port 10. The disc brake pad is clamped by the clamping plate 9. After the disc brake pad is fixed, the telescopic rod 3 drives the connecting plate 4 to move downward. The connecting plate 4 drives the grinding device 6 to move downward. The motor 5 drives the grinding device 6 to rotate. The grinding device 6 grinds the surface of the disc brake pad. The surface of the disc brake pad is cleaned by this device.

[0020] The clamping plate 9 includes a clamping seat 91. A crossbar 92 is fixedly connected to the center of the bottom of the clamping seat 91. A sliding block 93 is slidably connected to the outer surface of the crossbar 92. A clamping head 94 is fixedly connected to the top of the sliding block 93. An inclined block 95 is slidably connected to the outer surface of the sliding block 93. The outer surface of the inclined block 95 is slidably connected to the inner surface of the clamping seat 91. An electromagnet 96 is fixedly connected to the inner surface of the clamping seat 91. The electromagnet 96 pushes the inclined block 95 to slide. The inclined block 95 pushes the sliding block 93 to slide upward. The sliding block 93 drives the clamping head 94 to clamp the outer surface of the disc brake pad. The clamping plate 9 fixes the disc brake pad, making the disc brake pad firmly fixed.

[0021] The clamping head 94 includes a fixing plate 941, which is fixedly connected to the top of the sliding block 93. An arc-shaped plate 942 is rotatably connected to the side of the fixing plate 941 away from the sliding block 93. A straight plate 943 is fixedly connected to the bottom of the arc-shaped plate 942. The sliding block 93 drives the arc-shaped plate 942 to move inward. The arc-shaped plate 942 rotates under force and sticks to the surface of the disc brake pad, fixing the outer surface of the disc brake pad. The bottom of the disc brake pad sticks to the top of the straight plate 943. The clamping head 94 can fix irregular disc brake pads and fix disc brake pads of various specifications.

[0022] In use, the electromagnet 96 pushes the inclined block 95 to slide, the inclined block 95 pushes the sliding block 93 to slide upward, the sliding block 93 drives the arc plate 942 to move inward, the arc plate 942 rotates under force and sticks to the surface of the disc brake pad, which can fix the irregular disc brake pad. The bottom of the disc brake pad sticks to the top of the straight plate 943 to prevent the disc brake pad from moving downward under force during the grinding process.

[0023] Example 2: As Figures 5-9 As shown, the filter 11 includes a cuboid 111. The top of the cuboid 111 is fixedly connected to the top of the inner cavity of the base 1. A guide plate 112 is fixedly connected to the top of the cuboid 111. A straight column 113 is fixedly connected to the bottom of the guide plate 112. A diverter plate 114 is fixedly connected to the bottom of the straight column 113. The filter 11 can filter water flow. The water flow flows into the interior of the cuboid 111 along the guide plate 112 and flows to the surroundings along the diverter plate 114, making the water flow more dispersed when it enters the cuboid 111, thus avoiding the need for the same point of the corrugated screen plate 115 to filter a large amount of water flow in a short period of time.

[0024] A corrugated screen plate 115 is fixedly connected to the bottom of the cube 111. A filter hole 116 is opened on the top of the corrugated screen plate 115. After the water flows through the corrugated screen plate 115, the filtered dirt will slide to the bottom of the corrugated screen plate 115, which is convenient for the collection of dirt. The filter hole 116 is not easily blocked by dirt. The corrugated screen plate 115 makes the filter 11 less likely to be blocked by dirt.

[0025] The grinding device 6 includes a vertical column 61, a cylinder 62 slidably connected to the inner surface of the vertical column 61, a grinding disc 63 fixedly connected to the outer surface of the cylinder 62, a movable column 64 fixedly connected to the top of the inner cavity of the cylinder 62, and the bottom of the movable column 64 slidably connected to the bottom of the cylinder 62. The motor 5 drives the vertical column 61 to rotate, the vertical column 61 drives the cylinder 62 to rotate, and the cylinder 62 drives the grinding disc 63 and the movable column 64 to rotate. The grinding disc 63 grinds the surface of the disc brake pad, and when the movable column 64 encounters a gap, it can press against the bottom of the gap to grind the gap. The grinding device 6 can grind the gaps of the disc brake pad.

[0026] A column 65 is fixedly connected to the top of the cylinder 62. A horizontal plate 66 is fixedly connected to the outer surface of the column 65. An elastic plate 67 is slidably connected to the top of the horizontal plate 66. The outer surface of the elastic plate 67 is fixedly connected to the inner surface of the vertical column 61. The outer surfaces of the horizontal plate 66 and the elastic plate 67 are in contact with each other. When the vertical column 61 is pressed down, the elastic plate 67 drives the horizontal plate 66 to move downward. When the grinding disc 63 contacts the disc brake pad, the elastic plate 67 begins to bend due to the force from the horizontal plate 66. When the elastic plate 67 bends to a certain extent, the horizontal plate 66 slides over the surface of the elastic plate 67 and no longer contacts the lower surface of the elastic plate 67. The grinding disc 63 stops rubbing against the surface of the disc brake pad. The horizontal plate 66 and the elastic plate 67 work together to protect the disc brake pad.

[0027] The movable column 64 includes a cylinder 641. A spring 642 is fixedly connected to the top of the inner cavity of the cylinder 641. A sliding column 643 is fixedly connected to the bottom of the spring 642. A stop block 644 is fixedly connected to the outer surface of the sliding column 643. The outer surface of the stop block 644 is slidably connected to the bottom of the cylinder 62. When the grinding device 6 is grinding, the stop block 644 is forced to slide upward. The stop block 644 drives the sliding column 643 to slide upward. The sliding column 643 drives the spring 642 to compress. The stop block 644 moves upward and releases the bottom of the cylinder 641. The rust remover inside the cylinder 641 flows out. The movable column 64 can apply the rust remover to the surface of the disc brake pad during the grinding process.

[0028] In use, the motor 5 drives the vertical column 61 to rotate, which in turn drives the cylindrical column 62 to rotate. The cylindrical column 62 drives the grinding disc 63 and the movable column 64 to rotate. The grinding disc 63 grinds the surface of the disc brake pad. When the movable column 64 encounters a gap, it can press against the bottom of the gap to grind the gap. The grinding device 6 can grind the gaps in the disc brake pad. During grinding, the stop block 644 is forced to slide upward, which drives the sliding column 643 to slide upward. The stop block 644 moves upward and releases the bottom of the cylinder 641. The rust removal liquid inside the cylinder 641 flows out and, together with the grinding disc 63, grinds the surface of the disc brake pad. After grinding, the surface of the disc brake pad is rinsed by water flow. The water flows along the guide plate 112 into the interior of the cube 111 and flows around along the diverter plate 114. The water flows to the corrugated screen plate 115 for filtration.
