Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, and more specifically, to an automobile parts grinding device with high protection performance. Background Art

[0002] Auto parts are the foundation of every component of a car, including the engine, transmission, suspension system, brake system, and electronic control unit. Each part has a specific function to ensure the normal operation and driving safety of the car. The production of auto parts usually involves a large number of tubular workpieces. Injection molding is often used in the production of metal tubes (especially in metal and plastic composite applications) to improve production efficiency and the accuracy and consistency of the workpieces.

[0003] However, there are still some problems in the subsequent processing. For example, for long metal tubes that are injection molded, workers usually cut them into short tubes in a certain quantity according to the needs, which will cause the end face of the tube to be rough. Therefore, the end face of the tube needs to be polished to remove surface burrs. However, during the polishing process, the high-speed rotating polishing head is connected to the surface of the tube. While removing the burrs, the metal particles and powder generated will adhere to the surface of the polishing head and splash outward as it rotates, causing adverse effects on the processing environment and personnel health. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides an automobile parts grinding device with high protective performance to solve the problem in the prior art that during the grinding process, when the high-speed rotating grinding head contacts the surface of the pipe, metal particle chips will be generated. These chips will adhere to the grinding head and fly as it rotates, thereby causing adverse effects on the processing environment and the health of the workers.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a high-protection automobile parts grinding device, comprising

[0006] A base, the top of which is provided with a protective component, a manipulator, and a clamping component in sequence;

[0007] The protective assembly includes a cover box, a U-shaped frame, and a movable block. A visual window is provided on one side of the cover box, and the other end is mounted with side bolts of the movable block. The bottom of the U-shaped frame is fixedly mounted on the top of the base. A servo motor is provided on the top of the U-shaped frame, and a reciprocating screw is fixedly sleeved on the output end of the servo motor. The outer surfaces of both ends of the reciprocating screw are rotatably mounted on the inner surfaces of both ends of the U-shaped frame, and the outer surface of the reciprocating screw is rotatably mounted on the inner surface of the movable block. An I-shaped column is fixedly mounted on the middle part of the U-shaped frame, and the outer surface of the I-shaped column is slidably mounted on the inner surface of the movable block.

[0008] It also includes a driving motor and a grinding wheel. The top of the driving motor is fixedly installed with the end of the manipulator, and the middle of the grinding wheel is fixedly installed with the output end of the driving motor.

[0009] Among them, the clamping assembly includes a vertical plate, an electric push rod, and a screw. The bottom of the vertical plate is fixedly installed on the top surface of the base. The electric push rod is arranged inside the base, and the top end of the electric push rod is fixedly connected to a rack. The end of the screw is movably connected to the inner surface of the vertical plate. The outer surface of the end of the screw is fixedly installed with a gear. The gear and the rack are engaged with each other. The end of the screw away from the gear is fixedly installed with a top plate. The outer surface of the screw is threadedly connected to a sleeve, and a clamp mechanism is provided on the outside of the sleeve.

[0010] Among them, the clamping assembly also includes a ring and a limiting rod. The side of the ring is fixedly installed on the side end of the sleeve near the gear, the middle part of the ring is threadedly connected to the outer surface of the screw, the end of the limiting rod is fixedly installed on the surface of the vertical plate, and the outer surface of the limiting rod is slidably installed on the inner surface of the ring.

[0011] In which, the clamp mechanism includes a connecting bar, a connecting rod, a trapezoidal plate, and a spring. The side of the connecting bar is fixedly installed on the outer wall of the sleeve. There are four connecting rods. One end of the four connecting rods is movably connected to the surface of the connecting bar, and the other end is movably connected to the surface of the trapezoidal plate. A rubber splint is fixedly installed on the side of the trapezoidal plate away from the connecting rod. One end of the spring is fixedly connected to the surface of the connecting bar, and the other end is fixedly connected to the surface of the bottom of the trapezoidal plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] In the above scheme, a protective component is set up. After the pipe is fixed by the clamping component, the staff controls the servo motor to start, and the reciprocating screw connected to the output end of the servo motor rotates, so that the movable block connected with the external thread moves downward along the outer surface of the reciprocating screw and the outer surface of the I-shaped column, driving the cover box installed with the side bolts to move downward and cover the outside of the clamping component, the pipe clamped by the clamping component, the manipulator and other structures. Then, the end face of the pipe is polished by the manipulator, the drive motor and the grinding wheel to remove burrs. The above structure can avoid the generation of metal particle chips when the high-speed rotating grinding wheel contacts the surface of the pipe during the grinding process. These chips will adhere to the grinding wheel and splash as it rotates, thereby causing adverse effects on the processing environment and the health of the staff.

[0014] In the above scheme, by setting up a clamping assembly, the staff puts the pipe fitting on the outside of the clamp mechanism, and then controls the electric push rod to extend, pushing the connected rack upward while driving the meshing gear to rotate, so that the connected screw rotates, driving the threaded sleeve and the external clamp mechanism to move along the outer surface of the screw in the direction close to the top plate. During the movement, the trapezoidal plate will move in line with the side edge of the top plate, and due to its slope design, the trapezoidal plate drives the connecting rod to expand outward, driving the connected rubber splint to finally resist the inner wall of the pipe fitting, thereby achieving the fixation of the pipe fitting. By controlling the extension and retraction of the electric push rod, the rapid fixation and disassembly of the pipe fitting can be controlled, and it can adapt to the fixation of pipe fittings with different inner diameters.

[0021] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0022] As attached Figure 1 To the attached Figure 4 The embodiment of the utility model provides a high-protection automobile parts grinding device, comprising

[0023] Base 1, the top of the base 1 is provided with a protective component 2, a manipulator 3, and a clamping component 6 in sequence;

[0024] The protective assembly 2 includes a cover box 20, a U-shaped frame 22, and a movable block 25. A visual window 21 is provided on one side of the cover box 20, and the other end is bolted to the side of the movable block 25. The bottom of the U-shaped frame 22 is fixedly installed on the top of the base 1. A servo motor 23 is provided on the top of the U-shaped frame 22. The output end of the servo motor 23 is fixedly sleeved with a reciprocating screw 24. The outer surfaces of both ends of the reciprocating screw 24 are rotatably installed with the inner surfaces of both ends of the U-shaped frame 22. The outer surface of the reciprocating screw 24 is rotatably installed with the inner surface of the movable block 25. An I-shaped column 26 is fixedly installed in the middle of the U-shaped frame 22, and the outer surface of the I-shaped column 26 is slidably installed with the inner surface of the movable block 25.

[0025] It also includes a driving motor 4 and a grinding wheel 5 . The top of the driving motor 4 is fixedly mounted to the end of the manipulator 3 , and the middle of the grinding wheel 5 is fixedly mounted to the output end of the driving motor 4 .

[0026] Among them, the clamping assembly 6 includes a vertical plate 60, an electric push rod 61, and a screw 64. The bottom of the vertical plate 60 is fixedly installed on the top surface of the base 1. The electric push rod 61 is arranged inside the base 1, and the top of the electric push rod 61 is fixedly connected to the rack 62. The end of the screw 64 is movably connected to the inner surface of the vertical plate 60. The outer surface of the end of the screw 64 is fixedly installed with a gear 63. The gear 63 and the rack 62 are engaged with each other. The end of the screw 64 away from the gear 63 is fixedly installed with a top plate 65. The outer surface of the screw 64 is threadedly connected to the sleeve 66, and the outside of the sleeve 66 is provided with a clamp mechanism 67.

[0027] The clamping assembly 6 further includes a collar 68 and a limiting rod 69. The side of the collar 68 is fixedly mounted to the side end of the sleeve 66 near the gear 63. The middle portion of the collar 68 is threadedly connected to the outer surface of the screw 64. The end of the limiting rod 69 is fixedly mounted to the surface of the vertical plate 60. The outer surface of the limiting rod 69 is slidably mounted to the inner surface of the collar 68.

[0028] By setting the collar 68 and the limiting rod 69, when the sleeve 66 moves along the outer surface of the screw 64, the collar 68 at its side end will slide along the outer surface of the limiting rod 69, so that when the sleeve 66 moves, it will not be driven by the screw 64 and will produce idle rotation, providing a limiting effect.

[0029] The clamp mechanism 67 includes a connecting bar 670, a connecting rod 671, a trapezoidal plate 672, and a spring 674. The side of the connecting bar 670 is fixedly mounted to the outer wall of the sleeve 66. Four connecting rods 671 are provided. One end of the four connecting rods 671 is movably connected to the surface of the connecting bar 670, and the other end is movably connected to the surface of the trapezoidal plate 672. A rubber clamp 673 is fixedly mounted on the side of the trapezoidal plate 672 away from the connecting rod 671. One end of the spring 674 is fixedly connected to the surface of the connecting bar 670, and the other end is fixedly connected to the surface of the bottom of the trapezoidal plate 672.

[0030] By setting the spring 674, when the control sleeve 66 moves along the screw 64 toward the vertical plate 60 and the pipe fitting is relaxed, the spring 674 is reset by its own contraction, so that the trapezoidal plate 672 connected to the rubber splint 673 is retracted toward the connecting bar 670, assisting the recovery operation of the clamp mechanism 67.

[0031] The working process of this utility model is as follows:

[0032] First, the staff puts the pipe fitting on the outside of the clamp mechanism 67, and then controls the electric push rod 61 to extend, pushing the connected rack 62 to move upward while driving the meshing gear 63 to rotate, so that the connected screw 64 rotates, driving the threaded sleeve 66 and the external clamp mechanism 67 to move along the outer surface of the screw 64 in the direction close to the top plate 65. During the movement, the trapezoidal plate 672 will move along the side edge of the top plate 65. Due to the design of its slope, the trapezoidal plate 672 drives the connecting rod 671 to expand outward, driving the connected rubber splint 673 to finally abut against the inner wall of the pipe fitting, thereby achieving the fixation of the pipe fitting. By controlling the extension and retraction of the electric push rod 61, the rapid fixation and removal of the pipe fitting can be controlled, and it can adapt to the fixation of pipe fittings with different inner diameters.

[0033] After the pipe fitting is fixed by the clamping assembly 6, the staff controls the servo motor 23 to start, and the reciprocating screw 24 connected to the output end of the servo motor 23 rotates, so that the movable block 25 connected with the external thread moves downward along the outer surface of the reciprocating screw 24 and the outer surface of the I-shaped column 26, driving the cover box 20 installed with the side bolts to move downward, and cover the outside of the clamping assembly 6, the pipe fitting clamped by the clamping assembly 6, the manipulator 3 and other structures. Then, the end face of the pipe fitting is polished by the manipulator 3, the drive motor 4 and the grinding wheel 5 to remove burrs. The above structure can avoid the generation of metal particle chips when the high-speed rotating grinding wheel 5 contacts the surface of the pipe fitting during the grinding process. These chips will adhere to the grinding wheel 5 and splash as it rotates, thereby causing adverse effects on the processing environment and the health of the staff.
