Description

Technical Field

[0001] This utility model belongs to the field of surface treatment equipment for parts, and specifically relates to an anti-splash structure for processing and polishing automotive parts. Background Technology

[0002] When processing the sheet metal surfaces of automobiles, grinding devices are usually used to grind and finish the surface of the sheet metal formwork or sheet metal raw materials. A grinding wheel grinder with patent application number CN220660234U includes a base plate, a friction layer covering the upper surface of the lower end of the base plate, a support plate connected to the upper end of one side of the base plate, a grinding wheel rotatably connected to the inner wall of the support plate, a protective shell provided for the outer side of the grinding wheel, a groove opened on the upper end of the base plate corresponding to the position of the grinding wheel, a water storage box installed on the upper end of the protective shell, a support plate set on the base plate at the position of the grinding wheel, and an adjustment mechanism between the support plate and the base plate to adjust the height of the support plate. During the use of this utility model, the protective shell can block the iron filings generated during grinding, preventing them from splashing into the external environment and causing damage. At the same time, the water seepage hole can wet the entire grinding wheel, thereby cooling down the heat generated during grinding and preventing the workpiece from being affected by excessive heat.

[0003] However, this device has the following drawbacks in use. When grinding parts, although the protective shell can block the grinding debris, it only acts as a barrier and does not have a collection function. This means that after being blocked, the debris will still fill the vicinity of the automotive sheet metal parts, affecting the grinding environment or filling the gaps in the sheet metal parts, causing quality problems (such as the aluminum powder spraying incident in the air vents of a certain car company). It may even affect the observation of the grinding progress. At the same time, the relative position between the protective shell and the grinding wheel is fixed, and the protective shell cannot be adaptively adjusted according to the grinding depth. This means that the protective effect of the protective shell may become unstable due to changes in the grinding depth. Utility Model Content

[0004] The purpose of this invention is to provide an anti-splash structure for machining and polishing automotive parts, in order to solve the technical problems in the background art mentioned above, such as the inability to collect debris and the inability to adjust the position of the protective shell.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An anti-splash structure for grinding automotive parts includes: a fixed frame, side plates, and a grinding wheel; the side plates are two sets of parallel plate-like structures, fixed on both sides of the fixed frame; the main body of the grinding wheel is a roller shaft rotatably fitted between the two sets of side plates, and the roller shaft is provided with uniformly distributed grinding material; a power motor is fixed on one of the side plates, and the output shaft of the power motor and the roller shaft of the grinding wheel are concentrically fixed; a chip baffle that can move up and down is provided below the side of the fixed frame away from the grinding wheel, and a chip collecting cover is provided at the top of the chip baffle, which is connected to a negative pressure chip collecting device.

[0007] Furthermore: In order to facilitate the collection of chips after grinding by the chip collecting cover, the channel connecting the chip baffle and the chip collecting cover is a chip discharge port. In order to guide the grinding chips to the chip discharge port under the action of inertia, the lower end of the chip baffle on the side away from the grinding wheel is set with an inner arc angle to guide the transverse or near transverse flying chips to the chip discharge port.

[0008] Furthermore, in order to prevent the chip guard from scratching the workpiece when blocking chips, each side of the chip guard is equipped with an auxiliary wheel that rotates.

[0009] Furthermore: In order to further guide the turbulent flow of flying chips to the chip discharge port, an inclined guide plate is provided on each side of the chip discharge port inside the chip baffle. One side of the guide plate is fixed to the inner wall of the chip baffle, and the other side is fixed to the side opening of the chip discharge port.

[0010] Furthermore: In order to enable the position of the chip shield to be adaptively adjusted according to the grinding depth, the fixing frame is provided with at least one set of sliding sleeves directly above the grinding wheel. Each set of sliding sleeves is slidably fitted with a rod-shaped sliding rod. The lower part of the sliding rod is fixed to the upper top surface of the chip shield. A spring is provided between the top surface of the chip shield and the fixing frame, which is concentrically embedded in the sliding rod. The length of the spring must meet the following requirement: when the spring is in its normal state, the bottom of the auxiliary wheel and the bottom of the grinding wheel are located on the same horizontal plane.

[0011] Furthermore, to prevent the slide rod from detaching from the sleeve due to external force, a limiting head is provided at the top of the slide rod to prevent it from detaching from the sleeve.

[0012] Furthermore: In order to adjust the grinding depth of the grinding wheel in real time, a depth adjustment mechanism is provided above the fixed frame. The main body of the depth adjustment mechanism is a bracket structure mounting frame. A guide frame with a vertical frame structure is clamped in the middle of the mounting frame. At least three sets of pulleys in a circumferential array are provided at the upper and lower ends of the guide frame and the mounting frame, respectively. All pulleys are limited and rolled together by a rod-shaped sliding rod. The sliding rod is provided with a slide rail for the pulleys to roll together. The sliding rod can only slide up and down along the guide frame under the rolling engagement of the pulleys. The bottom of the sliding rod is fixedly connected to the fixed frame by a connecting frame. A rack parallel to its axis is provided on the sliding rod. A reduction motor is fixed on the mounting frame. A gear is fixed on the output shaft of the reduction motor. The gear and the rack mesh with each other.

[0013] Furthermore: In order to facilitate the connection of the floating chip collection hood to the negative pressure device, the chip collection hood is connected to the negative pressure device using a steel wire hose.

[0014] In summary, this utility model has the following beneficial effects:

[0015] ① It has a chip collection function. With the chip baffle and chip collection hood, the flying chips from the grinding wheel will be blocked by the chip baffle. The inner arc angle and guide plate on the chip baffle will guide the flying chips to the chip discharge port. Because the chip collection hood is connected to the negative pressure equipment, the chip discharge port connected to the chip collection hood will suck up and collect the flying chips, and then enter the steel wire hose through the chip collection hood. The flying chips will then enter the negative pressure equipment through the steel wire hose for collection.

[0016] ② The position of the chip shield can be adaptively adjusted according to the grinding depth to ensure that it is always in the direction of the chip flow: this is achieved through the establishment of a floating component; when a greater grinding depth is required, similarly, an external controller drives a geared motor, which in turn moves the fixed frame and grinding wheel downwards. At this time, the sliding sleeve on the fixed frame moves downwards along with the fixed frame, while the chip shield is limited to the surface of the automotive sheet metal by the auxiliary wheel. Therefore, the chip shield, auxiliary wheel, and sliding rod will maintain their original state, and the spring between the fixed frame and the chip shield is compressed to store elastic potential. Yes; the chip shield can still effectively block and collect the flying chips generated by the grinding wheel. When the grinding depth decreases, the same principle applies. The external controller drives the geared motor, which in turn moves the fixed frame and grinding wheel upward. At this time, the sliding sleeve on the fixed frame moves upward with the fixed frame, and the compressed spring releases its elastic potential energy, pressing the auxiliary wheel on the chip shield against the surface of the automotive sheet metal. Therefore, the chip shield and auxiliary wheel will maintain their original state, and the chip shield can still effectively block and collect the flying chips generated by the grinding wheel.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Example:

[0025] Please see Figures 1-5 The present invention provides the following technical solution:

[0026] An anti-splash structure for grinding automotive parts includes: a fixed frame 1, side plates 2, and a grinding wheel 3; the side plates 2 are two sets of parallel plate-like structures, fixed on both sides of the fixed frame 1; the main body of the grinding wheel 3 is a roller shaft rotatably fitted between the two sets of side plates 2, and the roller shaft is provided with uniformly distributed grinding material (the grinding material can be one of brush bristles, felt, sandpaper, or grinding wheel); a power motor 4 is fixed on one of the side plates 2, and the output shaft of the power motor 4 is concentrically fixed with the roller shaft of the grinding wheel 3; a chip baffle 5 that can move up and down is provided below the side of the fixed frame 1 away from the grinding wheel 3, and a chip collecting cover 8 is provided at the top of the chip baffle 5, which is connected to a negative pressure chip collecting device.

[0027] In order to facilitate the collection of chips after grinding by the chip collecting cover 8, the channel connecting the chip baffle 5 and the chip collecting cover 8 is a chip discharge port 52. In order to guide the grinding chips to the chip discharge port 52 under the action of inertia, the lower end of the chip baffle 5 on the side away from the grinding wheel 3 is provided with an inner arc angle 51 to guide the transverse or near transverse flying chips to the chip discharge port 52.

[0028] In order to prevent the chip shield 5 from scratching the workpiece when blocking chips, each side of the chip shield 5 is equipped with an auxiliary wheel 6.

[0029] In order to further guide the turbulent flow of flying chips to the chip discharge port 52, an inclined guide plate 53 is provided on each side of the chip discharge port 52 inside the chip baffle 5. One side of the guide plate 53 is fixed to the inner wall of the chip baffle 5, and the other side is fixed to the side opening of the chip discharge port 52.

[0030] In order to enable the position of the chip shield 5 to be adaptively adjusted according to the grinding depth, the fixing frame 1 is provided with at least one set of sliding sleeves 71 directly above the grinding wheel 3. Each set of sliding sleeves 71 is slidably fitted with a rod-shaped sliding rod 72. The lower part of the sliding rod 72 is fixed to the upper top surface of the chip shield 5. A spring 73 is provided between the top surface of the chip shield 5 and the fixing frame 1, which is concentrically embedded in the sliding rod 72. The length of the spring 73 should meet the following requirement: when the spring 73 is in its normal state, the bottom of the auxiliary wheel 6 and the bottom of the grinding wheel 3 are located on the same horizontal plane.

[0031] To prevent the slide rod 72 from detaching from the slide sleeve 71 due to external force, the top of the slide rod 72 is provided with a limiting head 74 to prevent it from detaching from the slide sleeve 71.

[0032] To enable real-time adjustment of the grinding depth of the grinding wheel 3, a depth adjustment mechanism 9 is provided above the fixed frame 1. The main body of the depth adjustment mechanism 9 is a bracket structure mounting frame 91. A vertical frame structure guide frame 98 is clamped in the middle of the mounting frame 91. At least three sets of pulleys 94 arranged in a circular array are provided at the upper and lower ends of the guide frame 98 and the mounting frame 91, respectively. All pulleys 94 are limited and rolled together by a rod-shaped sliding rod 92. The sliding rod 92 is provided with a slide rail 93 for the pulleys 94 to roll together. The sliding rod 92 can only slide up and down along the guide frame 98 under the rolling engagement of the pulleys 94. The bottom of the sliding rod 92 is fixedly connected to the fixed frame 1 by a connecting frame 10. The sliding rod 92 is provided with a rack 95 parallel to its axis. A geared motor 96 (the geared motor 96 is a servo motor with a reducer) is fixed on the mounting frame 91. A gear 97 is fixed on the output shaft of the geared motor 96. The gear 97 and the rack 95 mesh with each other.

[0033] To facilitate the connection of the floating chip collection hood 8 to the negative pressure device, the chip collection hood 8 is connected to the negative pressure device using a steel wire hose.

[0034] Brief description of usage:

[0035] When in use, the mounting bracket 91 can be fixedly installed according to the actual grinding requirements, or the mounting bracket 91 can be installed on the moving end of the robotic arm.

[0036] The chip collection hood 8 and the negative pressure equipment are connected by a steel wire hose, which provides an external power source for the power motor 4. The power motor 4 is powered and drives the grinding wheel 3 to work.

[0037] The automotive sheet metal surface 11 is positioned below the grinding wheel 3. It serves as an external power source and controller for the geared motor 96. When the geared motor 96 rotates, it drives the rack 95 to move up and down via the gear 97 on its drive shaft. The controller can then control the up and down movement of the rack 95 and the slide bar 92. Based on the above principle, the controller controls the geared motor 96 to drive the rack 95 and the slide bar 92 to move down as a whole. The slide bar 92 drives the fixed frame 1 to move down via the connecting frame 10. Consequently, the grinding wheel 3 connected to the side plate 2 on the fixed frame 1 moves down as well. When the rotating grinding wheel 3 moves down, it grinds or polishes the automotive sheet metal surface 11.

[0038] like Figure 5 As shown, the dust stream 12 from the grinding wheel 3 is blocked by the dust baffle 5. The inner arc angle 51 and the guide plate 53 on the dust baffle 5 will guide the dust stream 12 to the dust discharge port 52. Because the dust collection hood 8 is connected to the negative pressure equipment, the dust discharge port 52 connected to the dust collection hood 8 will suck up and collect the dust, and enter the steel wire hose through the dust collection hood 8. Then the dust enters the negative pressure equipment through the steel wire hose for collection.

[0039] When a greater grinding depth is required, similarly, the geared motor 96 is driven by an external controller. The geared motor 96 drives the fixed frame 1 and the grinding wheel 3 to move downwards. At this time, the sliding sleeve 71 on the fixed frame 1 moves downwards along with the fixed frame 1, while the chip shield 5 is limited to the surface of the automotive sheet metal 11 by the auxiliary wheel 6. Therefore, the chip shield 5, the auxiliary wheel 6, and the sliding rod 72 will maintain their original state. The spring between the fixed frame 1 and the chip shield 5 is compressed and stores elastic potential energy. The chip shield 5 is always located in the direction of the flying chip flow, and can still effectively block and collect the flying chip flow 12 generated by the grinding wheel 3.

[0040] When the grinding depth decreases, similarly to the above, the geared motor 96 is driven by an external controller. The geared motor 96 drives the fixed frame 1 and the grinding wheel 3 to move upward. At this time, the sliding sleeve 71 on the fixed frame 1 moves upward with the fixed frame 1. The compressed spring 73 releases its elastic potential energy and presses the auxiliary wheel 6 on the chip baffle 5 against the surface of the automotive sheet metal 11. Therefore, the chip baffle 5 and the auxiliary wheel 6 will maintain their original state (close to the automotive sheet metal 11). The chip baffle 5 is always located in the direction of the flying chip flow, and can still effectively block and collect the flying chip flow 12 generated by the grinding wheel 3.

[0041] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
