Description

Technical Field

[0001] This invention relates to the field of mechanical grinding technology, and in particular to a general-purpose grinding device for machining. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Its main function is to generate driving torque. As a power source for electrical appliances or various machines, its main function is to convert mechanical energy into electrical energy. The casing is an indispensable part of the motor, and a grinding device is needed when processing the casing.

[0003] Patent CN117140219B discloses a motor housing processing device with a grinding function, including a base, a mounting base, and a first servo motor. The mounting base is connected to the upper right side of the base, and the first servo motor is connected to the upper middle part of the mounting base. This invention utilizes the rotation of the first servo motor to drive the internal gear ring to rotate, thereby moving the lifting frame. The rotation of the lifting frame causes the sliding seat to move, causing the sliding seat to drive the outer wall grinding wheel to rotate in opposite directions with the motor housing. The outer wall grinding wheel then grinds the outer wall of the motor housing, achieving automatic grinding of the motor housing's outer wall and improving the grinding efficiency of the motor housing.

[0004] However, the above-mentioned invention patent still has some shortcomings in actual use: it cannot achieve synchronous grinding of the inner and outer walls. When clamping the outer wall of the motor housing, only the inner wall can be ground, and when clamping the inner wall of the motor housing, only the outer wall can be ground. It is very monotonous and inefficient. Moreover, the corresponding molds need to be changed multiple times for grinding the inner and outer walls. Therefore, this invention is proposed to solve the above-mentioned problems. Summary of the Invention

The bottom surface reinforcement grinding mechanism is mounted on the sliding frame three. In addition, an inner side reinforcing polishing mechanism is provided, which works in conjunction with the bottom surface reinforcing polishing mechanism to enhance the polishing effect of the motor housing on the inner wall. The inner side reinforcing polishing mechanism is mounted on the first mounting bracket.

[0007] Preferably, the outer wall of the third mounting bracket is fixedly connected to a bottom grinding disc, and the inner walls of the sliding bracket three and the two sliding brackets two are rotatably connected to positioning wheels.

[0009] Preferably, the clamping mechanism includes a first shaft, a first motor, a threaded groove, a first slide rod, a mounting rod, and a transmission gear. The first motor is fixedly connected to the base, the first shaft is fixedly connected to the output shaft of the first motor, the transmission gear is fixedly connected to the end of the first shaft, the first shaft is fixedly connected to the transmission gear, the threaded groove is formed on the rotating column, the first slide rod is slidably connected to the rotating column through the threaded groove, and the mounting rod is rotatably connected to the first slide rod.

[0010] Preferably, the mounting rod one is slidably connected to the fourth mounting bracket, the fourth mounting bracket is fixedly connected to the first mounting bracket, the inner wall of the mounting rod one is slidably connected to the mounting block one, two evenly distributed springs three are fixedly connected between the mounting block one and the mounting rod one, the bottom outer wall of the mounting block one is fixedly connected to the inner side wall grinding rod, and the outer wall of the inner side wall grinding rod is fixedly connected to the bottom grinding rod.

[0011] Preferably, the bottom surface strengthening and grinding mechanism includes a positioning rod, an upper limit plate, and a spring.

[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention uses a clamping mechanism to ensure that the outer wall grinding rod, positioning wheel, and two rotating wheels all abut against the outer wall of the motor housing. As the mounting rod moves downwards, the pressure rod contacts the upper limit plate, causing the upper limit plate to press against the motor housing. This forces the outer wall of the motor housing to remain in close contact with the bottom grinding disc, thus enhancing the bottom grinding effect. The pressure rod presses against the inner wall grinding rod, causing it to adhere tightly to the inner wall of the motor housing, thereby enhancing the internal grinding effect. The linked outer reinforcing grinding mechanism causes the transmission gear two to drive the outer wall grinding rod to rotate in the opposite direction, further enhancing the grinding effect of the outer wall grinding rod on the outer wall of the motor. This allows for simultaneous grinding of the inner wall, bottom, and outer wall of the clamped motor housing using a single rotation, resulting in extremely high efficiency and eliminating the need to switch between multiple grinding tools.

Figure 1 and Figure 2 As shown: When the first motor 12 rotates once, it drives the first shaft 11, the transmission gear 46, and the rotating column 10 to rotate once, causing the first slide rod 14 to move down along the threaded groove 13. The first slide rod 14 drives the mounting rod 15 and the mounting block 16 to move down. The mounting block 16 drives the inner side wall grinding rod 18 and the bottom grinding rod 9 to move down and extend into the inner wall of the motor housing.

[0022] Among them, the inner walls of the two sliding frames 45 are rotatably connected to rotating wheels 23, and the bottom outer walls of the two rotating wheels 23 are fixedly connected to third shafts 36.

[0023] The clamping mechanism 101 includes a first shaft 11, a first motor 12, a threaded groove 13, a first slide rod 14, a mounting rod 15, and a transmission gear 46.

[0024] In this implementation plan, such as Figure 2 , Figure 3 and Figure 6 As shown: Simultaneously, the transmission gear 5 46 rotates, driving the external gear ring 7 to rotate. The sliding frame 3 6, the sliding frame 1 20, and the two sliding frames 2 45 all slide along the corrugated ring 8, so that the sliding frame 3 6, the sliding frame 1 20, and the two sliding frames 2 45 all slide to the four protrusions of the corrugated ring 8, so that the outer wall grinding rod 19, the positioning wheel 22, and the two rotating wheels 23 all abut against the outer wall of the motor housing.

[0025] Among them, mounting rod 15 is slidably connected to the fourth mounting bracket 21, the fourth mounting bracket 21 is fixedly connected to the first mounting bracket 2, mounting block 16 is slidably connected to the inner wall of mounting rod 15, two evenly distributed springs 43 are fixedly connected between mounting block 16 and mounting rod 15, inner side wall grinding rod 18 is fixedly connected to the bottom outer wall of mounting block 16, and bottom grinding rod 9 is fixedly connected to the outer wall of inner side wall grinding rod 18.

[0026] The bottom surface strengthening and grinding mechanism 303 includes a positioning rod 44, an upper limit plate 38, and a spring 39. The upper limit plate 38 is slidably connected to the limit frame 35, and the spring 39 is fixedly connected between the upper limit plate 38 and the limit frame 35. The upper limit plate 38 is fixedly connected to the positioning rod 44. There are two bottom surface strengthening and grinding mechanisms 303.

[0027] In this implementation plan, simultaneously, Figure 7 and Figure 8As shown: During the downward movement of the mounting rod 15, the positioning rod 44 passes through the round hole at the end of the pressure rod 17, causing the positioning rod 44 to press and push the sliding plate 40, causing the sliding plate 40 to move in the direction of the pressing rod 41. The pressure rod 17 abuts against the upper limit plate 38, thereby causing the upper limit plate 38 to press the motor housing, forcing the outer wall of the motor housing to always be in close contact with the bottom grinding disc 25, thereby enhancing the grinding effect.

[0028] The inner strengthening grinding mechanism 404 includes a second spring 42, two pressure rods 17, two push slides 40, and two extrusion rods 41. The two pressure rods 17 are symmetrically distributed and are fixedly connected to the first mounting rod 15. The two push slides 40 are slidably connected to the two pressure rods 17 respectively. The two extrusion rods 41 are fixedly connected to the two push slides 40 respectively. Both ends of the second spring 42 are fixedly connected to the two extrusion rods 41.

[0029] In this implementation plan, such as Figure 9 As shown: At the same time, the extrusion rod 41 extrudes the inner wall grinding rod 18, so that the inner wall grinding rod 18 is in close contact with the inner wall of the motor housing, so that the inner wall grinding rod 18 and the bottom grinding rod 9 are in better contact with the inner wall of the motor housing.

[0031] like Figures 4-6 The rotation of the second motor 28 causes the drive gear 27 to drive the double-sided gear ring 26 to rotate. The double-sided gear ring 26 drives the two gears 24 to rotate, which in turn drives the two rotating wheels 23 to rotate via the third shaft 36. The two rotating wheels 23 drive the motor housing to rotate. At the same time, the transmission gear 33 meshes with the double-sided gear ring 26. The transmission gear 33 drives the transmission gear 31 to rotate via the second shaft 32. This causes the transmission gear 30 to drive the outer wall grinding rod 19 to rotate in the opposite direction, thus enhancing the grinding effect of the outer wall grinding rod 19 on the outer wall of the motor.

[0032] The working principle and usage of this invention are explained in detail below: In use, the motor housing is placed on the bottom grinding disc 25, as follows: Figure 1 and Figure 2As shown: When the first motor 12 rotates once, it drives the first shaft 11, the transmission gear 46, and the rotating column 10 to rotate once, causing the first slide rod 14 to move down along the threaded groove 13. The first slide rod 14 drives the mounting rod 15 and the mounting block 16 to move down. The mounting block 16 drives the inner side wall grinding rod 18 and the bottom grinding rod 9 to move down and extend into the inner wall of the motor housing.

[0033] like Figure 2 , Figure 3 and Figure 6 As shown: Simultaneously, the transmission gear 5 46 rotates, driving the external gear ring 7 to rotate. The sliding frame 3 6, the sliding frame 1 20, and the two sliding frames 2 45 all slide along the corrugated ring 8, so that the sliding frame 3 6, the sliding frame 1 20, and the two sliding frames 2 45 all slide to the four protrusions of the corrugated ring 8, so that the outer wall grinding rod 19, the positioning wheel 22, and the two rotating wheels 23 all abut against the outer wall of the motor housing.

[0034] At the same time, such as Figure 7 and Figure 8 As shown: During the downward movement of the mounting rod 15, the positioning rod 44 passes through the round hole at the end of the pressure rod 17, causing the positioning rod 44 to press and push the sliding plate 40, causing the sliding plate 40 to move in the direction of the pressing rod 41. The pressure rod 17 abuts against the upper limit plate 38, thereby causing the upper limit plate 38 to press the motor housing, forcing the outer wall of the motor housing to always be in close contact with the bottom grinding disc 25, thereby enhancing the grinding effect.

[0035] like Figure 9 As shown: At the same time, the extrusion rod 41 extrudes the inner wall grinding rod 18, so that the inner wall grinding rod 18 is in close contact with the inner wall of the motor housing, so that the inner wall grinding rod 18 and the bottom grinding rod 9 are in better contact with the inner wall of the motor housing.

[0036] like Figures 4-6 As shown: The rotation of the second motor 28 causes the drive gear 27 to drive the double-sided gear ring 26 to rotate. The double-sided gear ring 26 drives the two gears 24 to rotate, so that the gears 24 drive the two rotating wheels 23 to rotate through the third shaft 36. The two rotating wheels 23 drive the motor housing to rotate. At the same time, the transmission gear 33 meshes with the double-sided gear ring 26. The transmission gear 33 drives the transmission gear 31 to rotate through the second shaft 32, so that the transmission gear 30 drives the outer wall grinding rod 19 to rotate in the opposite direction, thereby enhancing the grinding effect of the outer wall grinding rod 19 on the outer wall of the motor.

[0037] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
