Description

Technical Field

[0001] This utility model relates to the technical field of mounting hole processing equipment, and in particular to a brake disc mounting hole processing device. Background Technology

[0002] Brakes are components in a braking system that generate braking force to impede the movement or tendency of a vehicle. Brake discs are the friction pairs of disc brakes. In addition to having the strength and rigidity required as components, they should also have the highest possible and most stable coefficient of friction, as well as appropriate wear resistance, heat resistance, heat dissipation and heat capacity. Since brake discs have many slots and holes, brake disc mounting hole machining equipment is essential for brake disc production.

[0003] Existing brake disc mounting hole machining equipment involves placing the brake disc on a platform, then starting a motor to drive the drill bit at high speed using gears and a chain drive. Simultaneously, a hydraulic rod moves the machine body up and down, causing the machine body to bring the drill bit to a position where it contacts the surface of the brake disc, generating high-speed friction with the surface. The drill bit then slowly feeds in and forms a hole, thus machining the mounting hole for the brake disc.

[0004] However, the drill bit generates dust when drilling holes in the brake disc, which then falls onto the worktable or floats in the air, making the machine dirty and easily inhaled by personnel, thus affecting the working environment and personnel health. Utility Model Content

[0005] The technical problem this invention aims to solve is that when the drill bit drills a hole in the brake disc, it generates dust that falls onto the worktable or floats in the air, making the machine dirty and easily inhaled by personnel, thus affecting the working environment and personnel health.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a brake disc mounting hole processing device, comprising: a machine body, which is placed on a table via a platform; a hydraulic rod, which is disposed between the platform and the machine body and is used to drive the machine body to move up and down; a drill bit, which is disposed on the machine body and is driven by a motor on one side of the machine body in conjunction with gears and a toothed chain; and a dust collection component, which is disposed on the side of the machine body near the drill bit and surrounds the drill bit to collect the dust generated during drilling.

[0007] Preferably, the dust collection assembly includes: a round hole rod fixedly connected to the side of the machine body near the drill bit; a dust collection ring slidably mounted on the round hole rod via a spring rod, wherein the other end of the spring rod is fixedly connected to the round hole rod; a rectangular cylinder fixedly connected to the machine body, wherein a fan is fixedly connected to one side of the rectangular cylinder, and a flexible hose is fixedly connected between the output end of the fan and the dust collection ring; and a collection box, the surface of which is slidably connected to the inner wall of the rectangular cylinder.

[0008] The effect achieved by the above components is as follows: By setting up the dust collection component, the spring rod, under the reaction force of the spring, pushes the dust collection ring towards the base plate. Under the push of the spring rod, the dust collection ring always remains in contact with or close to the surface of the brake disc. At this time, the fan is started, and the fan provides suction to the inside of the dust collection ring through the hose. The dust collection ring sucks the dust generated during the drilling process into the collection box inside the rectangular cylinder for storage. This achieves rapid collection and treatment of dust, reducing the dust generated during drilling from scattering on the platform or floating in the air, causing the machine to be dirty and easily inhaled by personnel, affecting the working environment and personnel health, and improving the convenience of dust cleaning.

[0009] Preferably, the dust collection assembly further includes: a ejector pin, wherein the ejector pin is uniformly fixed to the dust collection ring, and the surface of the ejector pin is higher than the dust collection ring.

[0010] The effect achieved by the above components is as follows: by setting the ejector pin, the ejector pin can be moved to a position that fits against the surface of the brake disc, separating the dust collection ring from the brake disc, so that a certain gap is always maintained between the two, thereby improving the dust collection effect of the dust collection ring.

[0011] Preferably, the dust collection assembly further includes a reinforcing block, wherein the reinforcing block is fixed between the round hole rod and the body.

[0012] The effect achieved by the above components is that by setting the reinforcing block, the connection strength between the round hole rod and the machine body can be increased, reducing the possibility of the round hole rod separating from the machine body during use.

[0013] Preferably, a viewing hole is provided on one side of the collection box, and a transparent plate is fixedly connected to the inner wall of the viewing hole.

[0014] The effect achieved by the above components is that by setting up viewing holes and transparent plates, personnel can observe the storage conditions inside the collection box through the viewing holes and transparent plates, which facilitates the rapid handling of dust by personnel.

[0015] Preferably, the vacuuming assembly further includes a collar, wherein the collar is fixed to the rectangular tube, and wherein the collar sleeves the hose inside.

[0016] The effect achieved by the above-mentioned components is that by setting a collar, the collar can be placed in the middle of the hose to limit its movement, thereby reducing the large-scale shaking of the hose during use.

[0017] Preferably, it further includes: a fixing component, the fixing component including: a chuck, the chuck being fixed to the platform, wherein the interior of the chuck has multiple circular grooves of different sizes, wherein the multiple circular grooves inside the chuck are arranged in a stepped manner; and auxiliary grooves, wherein the auxiliary grooves are opened on both sides of the chuck to assist personnel in removing the brake disc from the chuck.

[0018] The effect achieved by the above components is as follows: by setting the fixing components, the brake disc is first moved manually. When the brake disc moves to the position where it is inserted into the chuck, the brake disc is embedded in any circular groove in the chuck that matches its size. The chuck wraps around the brake disc and limits its position, thereby achieving rapid positioning of the brake disc. This reduces the shaking or sliding of the brake disc when it is placed on the table for processing, which affects the drilling quality and improves the stability and positioning convenience of the brake disc during the drilling process.

[0019] Preferably, the fixing component further includes: a rubber bump, wherein the rubber bump is uniformly fixed to the inner side of the chuck.

[0020] The effect achieved by the above components is that by setting rubber protrusions, the friction between the inner wall of the chuck and the surface of the brake disc can be increased, reducing the occurrence of brake disc rotation.

[0021] The beneficial effects of this utility model are:

[0022] By incorporating a dust extraction component, the dust generated during drilling can be quickly processed, reducing the amount of dust scattered on the worktable or floating in the air, which can cause the machine to become dirty and easily inhaled by personnel, affecting the working environment and personnel health, and improving the convenience of dust removal.

[0030] Figure 1-3 The device for machining brake disc mounting holes includes: a body 1, which is placed on a table via a platform 2; a hydraulic rod 3, which is disposed between the platform 2 and the body 1 and is used to drive the body 1 to move up and down; a drill bit 4, which is disposed on the body 1 and is driven by a motor on one side of the body 1 in conjunction with gears and a toothed chain; and a dust collection assembly 5, which is disposed on the side of the body 1 near the drill bit 4 and surrounds the drill bit 4 to collect the dust generated during drilling.

[0031] Figure 2The vacuuming assembly 5 shown includes: a round-hole rod 51, which is fixedly connected to the side of the machine body 1 near the drill bit 4; a vacuum ring 53, which is slidably mounted on the round-hole rod 51 via a spring rod 52, wherein the other end of the spring of the spring rod 52 is fixedly connected to the round-hole rod 51; a rectangular cylinder 54, which is fixedly connected to the machine body 1, wherein a fan 57 is fixedly connected to one side of the rectangular cylinder 54, and a flexible hose 56 is fixedly connected between the output end of the fan 57 and the vacuum ring 53; and a collection box 55, the surface of which is slidably connected to the inner wall of the rectangular cylinder 54. By setting the vacuuming assembly 5, the spring rod 52 is first pushed by the reaction force of the spring in the spring rod 52 to vacuum. The ring 53 moves closer to the base plate, so that the suction ring 53 is always in contact with or close to the surface of the brake disc under the push of the spring rod 52. At this time, the fan 57 is started, so that the fan 57 provides suction to the inside of the suction ring 53 through the hose 56, so that the suction ring 53 sucks the dust generated during the drilling process of the drill bit 4 into the collection box 55 inside the rectangular cylinder 54 for storage. This achieves rapid collection and treatment of dust, reduces the dust generated during drilling from scattering on the table 2 or floating in the air, causing the machine body 1 to be dirty and easily inhaled by personnel, affecting the working environment and personnel health, and improving the convenience of dust cleaning.

[0032] Figure 2 The dust collection assembly 5 shown also includes: a ejector pin 511, wherein the ejector pin 511 is uniformly fixed to the dust collection ring 53, wherein the surface of the ejector pin 511 is higher than the dust collection ring 53. By setting the ejector pin 511, the ejector pin 511 can be moved to a position that fits against the surface of the brake disc to separate the dust collection ring 53 from the brake disc, so that a certain gap is always maintained between the two, thereby improving the dust collection effect of the dust collection ring 53. The dust collection assembly 5 also includes: a reinforcing block 510, wherein the reinforcing block 510 is fixed between the round hole rod 51 and the body 1. By setting the reinforcing block 510, the connection strength between the round hole rod 51 and the body 1 can be increased, reducing the possibility of the round hole rod 51 separating from the body 1 during use.

[0033] Figure 2 The collection box 55 shown has a viewing hole 58 on one side, and a transparent plate is fixedly connected to the inner wall of the viewing hole 58. By setting the viewing hole 58 and the transparent plate, personnel can observe the storage situation inside the collection box 55 through the viewing hole 58 and the transparent plate, which facilitates the rapid handling of dust by personnel. The dust collection assembly 5 also includes a collar 59, which is fixed to the rectangular cylinder 54. The collar 59 covers the hose 56. By setting the collar 59, the collar 59 can be placed in the middle of the hose 56 to limit its movement and reduce the large-scale shaking of the hose 56 during use.

[0034] Figure 3The device also includes: a fixing component 6, which includes: a chuck 61 fixed to the table 2, wherein the interior of the chuck 61 has multiple circular grooves of different sizes, and the multiple circular grooves inside the chuck 61 are arranged in a stepped manner; and an auxiliary groove 62, wherein the auxiliary groove 62 is opened on both sides of the chuck 61 to assist the operator in removing the brake disc from the chuck 61. By setting the fixing component 6, the brake disc is first manually moved. When the brake disc moves to the position where it is inserted into the chuck 61, the brake disc is embedded in any circular groove in the chuck 61 that matches its size. This allows the chuck 61 to wrap around and limit the brake disc, thereby achieving rapid positioning of the brake disc. This reduces the possibility of the brake disc shaking or sliding when placed on the table 2 for processing, which affects the drilling quality and improves the stability and positioning convenience of the brake disc during the drilling process.

[0035] Figure 3 The fixing component 6 shown also includes a rubber protrusion 63, wherein the rubber protrusion 63 is uniformly fixed to the inner side of the chuck 61. By setting the rubber protrusion 63, the friction between the inner wall of the chuck 61 and the surface of the brake disc can be increased, reducing the occurrence of rotation of the brake disc.

[0036] Working principle: First, under the reaction force of the spring in the spring rod 52, the spring rod 52 pushes the dust suction ring 53 to move closer to the bottom plate, causing the dust suction ring 53 to drive the ejector pin 511 to move. Under the push of the spring rod 52, the ejector pin 511 always maintains a position in contact with the surface of the brake disc, so that the dust suction ring 53 and the brake disc always maintain a certain distance. At this time, the fan 57 is started, so that the fan 57 provides suction to the inside of the dust suction ring 53 through the hose 56, so that the dust suction ring 53 sucks the dust generated during the drilling process of the drill bit 4 into the collection box 55 inside the rectangular cylinder 54 for storage, thereby achieving rapid collection and treatment of dust.

[0037] First, manually move the brake disc. When the brake disc moves to the position where it is inserted into the chuck 61, it will be embedded in any of the circular grooves in the chuck 61 that are compatible with its size. The chuck 61 will then wrap around the brake disc and limit its movement, thus achieving rapid positioning of the brake disc. At this time, start the motor on one side of the machine body 1, which will work with gears and chains to drive the drill bit 4 to rotate at high speed. At the same time, the hydraulic rod 3 will drive the machine body 1 to move up and down, so that the machine body 1 will move the drill bit 4 to a position where it is in contact with the surface of the brake disc, generating high-speed friction with the surface. Then the drill bit 4 will slowly feed in and form a hole, thus machining the mounting hole of the brake disc.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
