Description

Technical Field

[0001] The utility model relates to the field of automobile component processing, in particular to a grinding device for processing and clamping automobile flanges. Background Art

[0002] Automobile flange processing and clamping grinding device, that is, flange grinding device with clamping function. The automobile flange processed by it is the standard interface part used to connect pipes, valves and other equipment in the automobile piping system. They usually have a circular shape with bolt holes on the edge for connection with other flanges or accessories. In the processing of automobile flanges, grinding is an important step. It is usually used to remove burrs, flash or surface defects generated during casting, forging or cutting.

[0003] During the outer edge grinding process of automotive flanges, since both the upper and lower edges need to be processed, the flange must be flipped during the grinding operation, which increases the complexity and time required for the operation. At the same time, each flip increases the chance of the operator's hand coming into contact with the grinding tool, which in turn increases the risk of contact between the grinding tool and the hand.

[0004] Therefore, in order to solve the above-mentioned problem that when grinding the upper and lower edges of the automobile flange, flipping the flange increases the complexity of the operation, increases the time required for the operation, and increases the possibility of contact between the grinding tool and the hand, a grinding device for clamping automobile flange processing can be designed to solve the above-mentioned problem. Utility Model Content

[0005] In order to overcome the problem that during the grinding process of the outer edge of the automobile flange, both the upper and lower edges need to be processed, the flange must be turned over during the grinding operation, which increases the complexity and time required for the operation, and also increases the possibility of contact between the grinding tool and the hand.

[0007] Preferably, in normal state, the positioning clamp blocks the rear end of the lower hexagonal sleeve, and the gear plate at the lower end also meshes with the gear mounted on the second rotary cylinder, so that the positioning clamp blocks and the gear can jointly prevent the lower mounting plate from rotating when the bolt is tightened. In addition, when the lower mounting plate or the upper mounting plate is placed in the limit groove, the gear plate is located at the lower end of the limit groove. When in use, after the flange is placed on the lower mounting plate, the slide and the support arm are lowered by the double-screw slide rail to allow the upper mounting plate to dock and press on the lower mounting plate and the flange, and then the lower mounting plate, flange and The upper mounting plate is tightened together, and then, according to the size of the flange, the motor and the grinding plate are actively displaced backward through the electric slider and the electric slide rail to contact the flange. The above device is suitable for flanges of different sizes. Because the rear end of the rear tilt plate is higher than the front end, the angle of the motor and the grinding plate will also be tilted, so that the grinding plate driven by the motor can grind the edge below the flange. Then, the second rotary cylinder rotates the gear to make the lower mounting plate, flange and upper mounting plate rotate together at a uniform speed for one circle through the gear plate at the lower end, and then rotate and reset to make the flange The lower edge can be polished when it is in contact with the polishing disc, and then the slide and the support arm are raised by the double-screw slide rail to lift the lower mounting plate, the flange and the upper mounting plate, and then the support arm, the lower mounting plate, the flange and the upper mounting plate are flipped over by the first rotary cylinder, and the upper mounting plate is placed in the limit groove by the double-screw slide rail, and then the lower mounting plate, the flange and the upper mounting plate are rotated together at a uniform speed for one circle again by the second rotary cylinder, the gear and the gear plate, so that the upper edge of the flange can also be polished when it is in contact with the polishing disc, thereby quickly completing the flipping step and reducing the cost. Low time consumption and error probability. Under normal circumstances, the motor and grinding disc will be retracted to the bottom of the limit slot by the lifting cylinder, but when the bolt is tightened downward, the lower end of the bolt will contact and press the switch, and when the upper mounting plate is flipped over and placed in the limit slot, the upper end of the bolt will also contact and press the switch. When the press switch is pressed, the lifting cylinder will push the tilt plate to push the motor and grinding disc out to the top of the limit slot, so that the grinding disc can protrude during grinding and be retracted when the operator moves the flange, thereby reducing the risk of safety accidents.

[0008] Preferably, the limiting groove, the lower mounting plate and the upper mounting plate are divided into two layers, and the thickness of each layer and the total thickness of the three are the same. The lower mounting plate is docked with the upper mounting plate, and the groove on the inner side of the positioning clamp can engage with the lower hexagonal sleeve.

[0009] Preferably, the protective assembly includes a base installed at the rear end of the horizontal push cylinder, a push switch is installed on the base, and the push switch is located at the lower end of the lower hexagonal sleeve.

[0010] Preferably, a second rotary cylinder is provided at the front end of the push switch, and the second rotary cylinder is installed on the base.

[0011] Preferably, a gear is installed on the upper end of the second rotary cylinder, and the gear is engaged with the gear plate, and a lifting cylinder is installed at the front end of the pad table.

[0012] Preferably, a tilting plate is mounted on the upper end of the lifting cylinder, a motor is mounted on the upper end of the tilting plate, and a grinding disc is mounted on the rear end of the motor.

[0013] Preferably, two electric sliders are installed on both sides of the lower end of the pad table, the lower ends of the electric sliders are electrically connected to electric slide rails, and the two electric slide rails on the same side are fixedly connected to each other.

[0014] Beneficial effects of the utility model:

The rear end of the slide 308 is installed with a first rotary cylinder 309, and the first rotary cylinder 309 is fixed to the support arm 307. The slide 308 is loosely matched with a double-screw slide rail 310, and the rear end of the lower hexagonal sleeve 304 is provided with a positioning clamp 311, and the rear end of the positioning clamp 311 is installed with a horizontal push cylinder 312. Two electric sliders 5 are installed on both sides of the lower end of the pad table 1, and the lower ends of the electric sliders 5 are electrically connected to the electric slide rails 6, and the two electric slide rails 6 on the same side are fixed to each other.

[0025] See also Figure 3 and Figure 6In this embodiment, the limiting groove 2, the lower mounting plate 301 and the upper mounting plate 302 are divided into two layers, and the thickness of each layer and the total thickness of the three are the same. The lower mounting plate 301 is docked with the upper mounting plate 302, and the groove on the inner side of the positioning clamp 311 can be engaged with the lower hexagonal sleeve 304. The protective component includes a base 401 installed at the rear end of the horizontal push cylinder 312. A press switch 402 is installed on the base 401, and the press switch 402 is located at the lower end of the lower hexagonal sleeve 304. Pressing the switch A second rotary cylinder 403 is provided at the front end of the switch 402, and the second rotary cylinder 403 is installed on the base 401. A gear 404 is installed at the upper end of the second rotary cylinder 403, and the gear 404 is engaged with the gear disc 303. A lifting cylinder 405 is installed at the front end of the pad table 1, and a rear tilting plate 406 is installed at the upper end of the lifting cylinder 405, and the rear end of the rear tilting plate 406 is higher than the front end. A motor 407 is installed at the upper end of the rear tilting plate 406, and a grinding disc 408 is installed at the rear end of the motor 407.

[0026] In normal operation, the positioning clamp 311 clamps the rear end of the lower hexagonal sleeve 304, and the gear plate 303 at the lower end also meshes with the gear 404 mounted on the second rotary cylinder 403, so that the positioning clamp 311 and the gear 404 can jointly prevent the lower mounting plate 301 from rotating when the bolt 306 is tightened. In addition, when the lower mounting plate 301 or the upper mounting plate 302 is placed in the limiting groove 2, the gear plate 303 is located at the lower end of the limiting groove 2;

[0027] During use, after placing the flange on the lower mounting plate 301, the slide 308 and the support arm 307 are lowered by the double-screw slide rail 310, so that the upper mounting plate 302 is docked and pressed against the lower mounting plate 301 and the flange, and then the lower mounting plate 301, the flange and the upper mounting plate 302 are tightened together by the bolts 306;

[0028] Then, according to the size of the flange, the motor 407 and the grinding disc 408 are actively displaced backwards by the electric slider 5 and the electric slide rail 6 to contact the flange. The above device is applicable to flanges of different sizes. Because the rear end of the rear tilt plate 406 is higher than the front end, the angles of the motor 407 and the grinding disc 408 are also tilted, so that the grinding disc 408 driven by the motor 407 can grind the edge below the flange.
