[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] Example 1: A throttle body shaft edge grinding and positioning fixture: including a loading platform 1, a base 2, an electric turntable 3, a side frame 5, and a shaft seat burr pressing and grinding unit. An electric drive shaft 21 is installed on the top of the base 2. The loading platform 1 is installed on the rotating end of the electric drive shaft 21. The electric turntable 3 is embedded in the surface of the loading platform 1. The shaft seat grinding and pressing loading unit is provided on the surface of the electric turntable 3. The side frame 5 is installed on one side of the bottom of the loading platform 1. The shaft seat burr pressing and grinding unit is located on the top of the side frame 5.

[0025] The bearing grinding and pressurizing loading unit includes a bracket 4, which is mounted on the rotating end of the electric turntable 3. A limit plate 43 is also mounted on the rotating end of the electric turntable 3. A slide 42 is slidably mounted on the surface of the limit plate 43. A clamping platform 44 is mounted on one end of the slide 42. A clamping platform 45 is mounted on the top of the clamping platform 44. A cylinder 41 is mounted on the top of the bracket 4. The movable end of the cylinder 41 is fixed to one side of the surface of the clamping platform 44.

[0026] The inner wall of clamping platform 2 45 is set in an arc shape, and the inner wall of clamping platform 2 45 is vertically arranged with rubber ring 1 451, rubber ring 2 452 and rubber ring 3 453 in sequence.

[0027] The bearing burr pressing and polishing unit includes a polishing part 1, which includes a fixing frame 6. The fixing frame 6 is installed on the top of the side frame 5. A polishing frame 8 is installed on the outside of the fixing frame 6. A stepper motor 81 is embedded in one end of the polishing frame 8. A rotating seat 82 is installed on the rotating end of the stepper motor 81. The rotating seat 82 is set in an arc shape. Grinding rollers 83 are arranged in an arc shape on the surface of the rotating seat 82.

[0028] The bearing burr pressing and polishing unit also includes a polishing section two, which includes a polishing frame two 9. The polishing frame two 9 is installed at the bottom of the fixed frame 6. A stepper motor two 91 is embedded in the surface of the polishing frame two 9. A rotating seat two 92 is installed on the rotating end of the stepper motor two 91. The rotating seat two 92 is also arc-shaped. Grinding rollers two 93 are arranged in an arc on the surface of the rotating seat two 92.

[0029] In this embodiment, by driving stepper motor 81 and stepper motor 91, stepper motor 81 drives the rotating seat 82 to flip up in reverse. During the reverse flipping process of rotating seat 82, the grinding roller 83 installed on rotating seat 82 will come into contact with the rough edge area on the surface of the door hinge. Simultaneously, stepper motor 91 drives rotating seat 92 to flip down in the forward direction. The grinding roller 93 installed on the surface of rotating seat 92 will insert and fit into the rough edge area of ​​the inner cavity of the door hinge. Then, by driving electric turntable 3 to drive the door hinge workpiece to rotate, grinding roller 83 and grinding roller 93 will realize the grinding steps of the outer surface and inner cavity surface of the door hinge workpiece, ensuring the grinding effect of the door hinge workpiece.

[0030] Example 2:

[0031] Based on Embodiment 1, this embodiment takes into account that if the surface of the aluminum can is dried by external gas circulation contact drying, the part of the aluminum can that first comes into contact with the gas will be dried first, which will also cause the internal energy of the gas in that area to decrease and the flow rate to decrease, thereby affecting the drying effect on other areas of the aluminum can surface. Therefore, this embodiment is provided with a guide part to avoid the above problems.

[0032] The bearing burr pressing and polishing unit also includes a dust removal section, which includes a filter air chamber 7. The filter air chamber 7 is installed on the side of the fixed frame 6 away from the polishing frame 9. An air intake pipe 71 is installed on one side of the filter air chamber 7. One end of the air intake pipe 71 passes through the fixed frame 6 and faces the polishing frame 9.

[0033] In this embodiment, the air pump outside the filter chamber 7 continuously draws air from inside the filter chamber 7. One end of the suction pipe 71 connected to the outside of the filter chamber 7 faces the area of ​​the first grinding roller 83 and the second grinding roller 93. When the first grinding roller 83 and the second grinding roller 93 are grinding, the grinding dust generated will be promptly drawn out by the suction pipe 71 and injected into the filter chamber 7 for effective filtration, ensuring the grinding conditions of the first grinding roller 83 and the second grinding roller 93.

[0034] Working principle: The operator places the door hinge parts to be ground in batches on the electric turntable 3 on the top of the loading platform 1. The electric turntable 3 is equipped with clamping platform 1 44 and clamping platform 2 45 for positioning and installing the door hinge parts. Clamping platform 1 44 is used to clamp and position the lower part of the door hinge part, and clamping platform 2 45 is used to clamp and position the top part of the door hinge part. The interior of clamping platform 2 45 is arc-shaped. The arc-shaped inner cavity of clamping platform 2 45 has rubber rings 1 451, 2 452 and 3 453 vertically distributed. This reduces the wear of rigid clamping of the door hinge part when clamping the upper part of the door hinge part, and also reduces the slippage of the workpiece when grinding the edge of the door hinge part, ensuring the effective performance of the grinding step.

[0035] During the calibration and installation of the door hinge components, the adjacent clamping platforms 44 can be pushed closer together by the drive cylinder 41. When the clamping platforms 44 move, the slide 42 located at the bottom of the clamping platforms 44 will slide along the surface of the limiting plate 43. The limiting plate 43 can restrict the sliding area of ​​the slide 42 to avoid excessive clamping damage to the door hinge components. After the door hinge components are positioned and installed, the burrs on the inner and outer surfaces of the door hinge components can be removed. At this time, stepper motors 81 and 91 can be driven. Stepper motor 81 drives the rotating base 1. Part 82 flips up in reverse. During the reverse flipping process of rotating seat 82, the grinding roller 83 installed on rotating seat 82 will come into contact with the rough edge area on the surface of the door hinge. The synchronous drive stepper motor 91 will drive rotating seat 92 to flip down in the forward direction. The grinding roller 93 installed on the surface of rotating seat 92 will insert and fit into the rough edge area of ​​the inner cavity of the door hinge. Then, the door hinge workpiece will be rotated by driving electric turntable 3. The grinding roller 83 and the grinding roller 93 will realize the grinding steps of the outer surface and inner cavity surface of the door hinge workpiece, ensuring the grinding effect of the door hinge workpiece.

[0036] When grinding roller 1 (83) and grinding roller 2 (93) are grinding the door hinge workpiece, in order to avoid dust splashing during grinding, an air pump external to the filter air chamber 7 can continuously draw air from inside the filter air chamber 7. One end of the suction pipe 71 connected to the outside of the filter air chamber 7 faces the area of ​​grinding roller 1 (83) and grinding roller 2 (93). When grinding roller 1 (83) and grinding roller 2 (93) are grinding, the grinding dust generated will be promptly drawn out by the suction pipe 71 and injected into the filter air chamber 7 for effective filtration, ensuring the grinding conditions of grinding roller 1 (83) and grinding roller 2 (93).

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
