Description

Technical Field

[0001] The present application relates to the technical field of mechanical parts processing, and in particular to a device for removing burrs from the surface of mechanical parts. Background Art

[0002] Deburring the surface of mechanical parts refers to the process of removing or trimming the burrs generated after machining mechanical parts. During the machining process, due to cutting, stamping, casting and other process operations, some irregular protrusions or burrs may appear on the surface of the parts. These burrs may affect the appearance, quality and performance of the parts. Therefore, in order to improve the quality and precision of the parts, it is often necessary to deburr the surface of the parts;

[0003] In the utility model with the Chinese patent authorization announcement number "CN211163222U", "a device for removing burrs from the surface of mechanical parts is disclosed, including a box body and a grinding unit; the box body: the interior of the box body is hollow, and an electric push rod is provided on the right side of the bottom of the box body, and the upper end of the electric push rod is fixedly connected to the middle part of the lower surface of the support plate, and a rotating motor is provided on the right side of the lower surface of the box body, and the output shaft of the rotating motor passes through the lower surface of the box body and is fixedly connected to the lower end of the electric push rod; the grinding unit includes a grinding motor, a grinding roller, a telescopic rod, a mounting seat and a spring, and the left end of the telescopic rod is fixedly connected to the middle part of the left side wall of the box body, and the right end of the telescopic rod is fixedly connected to the middle part of the left side surface of the mounting seat." Through the grinding unit, the grinding roller can be closely attached to the surface of the part for grinding and deburring, avoiding uneven grinding, making the size of the mechanical part after deburring within the error range, reducing the scrap rate of the part, and the cylindrical part can be fixed on the supporting plate through the fixing unit to prevent the part from shaking during grinding;

[0004] With respect to the above-mentioned related technologies, the inventor believes that in the above-mentioned utility model, it is necessary to manually rotate the screw in the fixing unit to drive the support block to move, support the inner wall of the cylindrical part, and fix it. Therefore, each time the parts are fixed and disassembled, they need to be manually performed, and the number of turns and strength of each rotation need to be observed by the staff based on their work experience and naked eyes. Therefore, due to more or less turns, the clamping force may be too large to cause deformation of the parts, or the force may be too small to completely fix the parts, so that when grinding and deburring, the parts may fall off and deviate, etc., affecting the processing quality. Moreover, the above-mentioned grinding roller is relatively long. Although the grinding roller can be driven by the telescopic rod to approach the parts for grinding, some parts may have grooves on their surfaces. When the grinding roller is moved, it may be blocked by the outside of the parts, so that the grinding roller may not be convenient to move close to the groove position of the parts to grind and remove the burrs in the grooves, which will also affect the overall processing quality.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

Since the fixing part is arranged in the slide groove 16, the fixing part is limited, so that the fixing part can be driven to move by using several groups of push-pull rods 14 on the surface of the fixing plate 13 at the bottom of the cylinder 12, so as to support and fix the inner wall of the cylindrical part. After being fixed, the first motor 3 can be used for output, so as to drive the fixing frame 2 And the fixed parts rotate, so as to facilitate the grinding and deburring of different positions on the surface of the parts, and the output is provided by the second motor 5, so as to drive the screw 6 in the sliding frame 4 to rotate, so that the linear actuator 8 and the grinding piece at the bottom thereof can be driven to move left and right through the threaded sleeve 7, so as to facilitate the grinding piece to be moved close to the surface of the parts and to the groove position of the parts, and at the same time, the height of the grinding piece can be adjusted by utilizing the extension and retraction of the linear actuator 8, so as to perform grinding and deburring on different height positions of the parts.

[0024] By adopting the above technical scheme, when multiple groups of push-pull rods 14 move, the multiple groups of slide grooves 16 have a limiting effect on the slider 15, so that the push-pull rods 14 can drive the slider 15 to move linearly in the slide groove 16, thereby driving multiple groups of fixed plates 17 to move, so as to facilitate the fixation of its parts for disassembly, and through the elastic anti-slip pads 18, not only can the stability of the support and fixation of the inner wall of the parts be improved, but also excessive support force can be avoided, causing wear of the inner wall of the parts, etc., and through the output of the third motor 10, the fixed rod 19 can be driven to rotate, thereby driving the grinding wheel 11 provided in the grinding frame 9 to rotate, and the rapid rotation of the grinding wheel 11 can be used to grind the burrs on the surface of the parts to remove the burrs.

[0025] The implementation principle of a deburring device for the surface of a mechanical part in the embodiment of the present application is as follows: a relatively sealed environment can be provided for the deburring of the parts through the processing box 1, so that the burrs and debris produced by the grinding process are prevented from splashing everywhere, and the output is telescopically provided through the cylinder 12, and the limiting effect of the slider 15 is exerted on the slider 15 through the multiple groups of slide grooves 16, so that the slider 15 can be driven to move linearly in the slide groove 16 through the multiple groups of push-pull rods 14 on the surface of the fixed plate 13, thereby driving the multiple groups of fixed plates 17 to move, so as to facilitate the fixing of the parts for disassembly, and the elastic anti-skid pad 18 can not only improve the stability of the support and fixation of the inner wall of the parts, but also avoid excessive support force causing wear on the inner wall of the parts, etc. After fixation, the output can be provided through the first motor 3, so as to drive the fixed frame 2 and the fixed parts to rotate, so as to facilitate the removal of the parts.

At the same time, the height of the grinding piece can be adjusted by utilizing the extension and retraction of the linear actuator 8, so that the grinding and deburring treatment is performed on different height positions of the part. After adjusting the position of the grinding piece, the output can be performed through the third motor 10, which can drive the fixed rod 19 to rotate, thereby driving the grinding wheel 11 in the grinding frame 9 to rotate, and utilizing the rapid rotation of the grinding wheel 11 to grind the burrs on the surface of the part and remove the burrs. The first motor 3, the second motor 5 and the third motor 10 mentioned above can all be NEMA 17 stepper motor, NEMA 17 stepper motor is a synchronous motor, which controls the movement of the rotor by applying a pulse signal. The rotation angle of the stepper motor is usually controlled by controlling the number of input pulses. Each time a pulse signal is received, the stepper motor will rotate a fixed angle, which is called the step angle. The rotation direction of the stepper motor is determined by the sequence of the input pulse signals and the direction of the current. The forward and reverse rotation of the motor can be achieved by controlling the pulse sequence and the direction of the current. The above-mentioned linear actuator 8 can use a linear actuator 8 with a self-locking function, the model is Warner Linear K2G20-12v-BR-04, and the linear actuator contains an electric motor, which is connected to the screw through a gear box to drive the screw to rotate. When the screw rotates, the push rod connected to the screw will move linearly to achieve the extension and retraction of the actuator.The whole process does not involve rotational movement of any parts. When the motor stops working, the friction between the screw and the nut and the design of the gear box ensure that the push rod will not move due to external forces, thereby realizing the self-locking function. The above-mentioned cylinder 12 can select DSNU-32-50-PA type cylinder 12. The cylinder 12 is a double-acting cylinder 12, which means that the cylinder 12 can control the intake and exhaust respectively through two different pipelines to realize push-pull action. When the cylinder 12 is inflated, the cylinder 12 piston will push outward, and when the air is exhausted, the cylinder piston will retract inward. By controlling the on and off of the air source, the workpiece can be fixed and disassembled and loosened. The overall operation is simple and easy to use, which can further improve the processing quality of its parts.
