Description

Technical Field

[0001] The invention relates to the technical field of flange processing, in particular to a positioning grinder structure. Background Art

[0002] Flange, also known as flange or flange, is a part that connects shafts to each other and is also used to connect pipe ends. The flange processing process usually includes raw material preparation, forging (casting), rough machining, fine machining, grinding, inspection and packaging. Among them, grinding is an indispensable step in flange processing. The main purpose is to remove burrs, oxide scales, stains, etc. on the flange surface to improve the surface quality and aesthetics of the flange, and also help improve the sealing performance of the flange.

[0003] During the grinding process, workers usually use various grinding tools, such as grinding wheels, sandpaper, grinding heads, etc., to perform fine processing on the flange surface. However, workers need to have high operating skills and experience to hold the grinding tools, otherwise it is difficult to ensure the uniformity and consistency of grinding, resulting in uneven surface quality of the flange. Due to the lack of effective positioning devices, it is easy to accidentally touch other areas during the grinding process, causing unnecessary damage. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art and to propose a positioning grinder structure to solve the problems of poor grinding effect, uneven surface after grinding and high difficulty coefficient of manual operation in the above technical scheme.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a positioning grinder structure, including a pneumatic or electric file tool, a fixing clamp ring is installed on the pneumatic or electric file tool, a locking nut is installed on the pneumatic or electric file tool, a rocker arm is installed on one side of the pneumatic or electric file tool, a fixing rod is installed on the fixing clamp ring, an M nut is installed on the outer side of the fixing rod, a positioning core is fixedly connected to the other side of the fixing rod, a vibration disk is installed at the bottom of the rocker arm, a mounting nut is installed on the top of the vibration disk, a brushed chassis is fixedly connected to the bottom of the vibration disk, and sandpaper is installed at the bottom of the brushed chassis; An adjusting component is arranged inside the positioning core, and the adjusting component is used for positioning a flange whose flange hole diameter is larger than the positioning core diameter.

[0006] As a preferred implementation, the fixing clamp is fixed to the pneumatic or electric file tool via a locking nut, and one side of the pneumatic or electric file tool is connected to the rocker arm via an M nut.

[0007] The beneficial effect of adopting the above-mentioned further scheme is that the fixing clamp is firmly fixed to the pneumatic or electric file tool by the locking nut, thereby ensuring the stability and durability of the structure. At the same time, the pneumatic or electric file tool is connected to the rocker arm by the M nut. This connection method is simple and firm, which is convenient for maintenance and replacement of parts, and improves the reliability and practicality of the overall structure.

[0008] As a preferred embodiment, two M nuts are installed on the outer side of the fixing rod, and the two M nuts are tightly fitted with the two side surfaces of the fixing clamp respectively.

[0009] The beneficial effect of adopting the above further scheme is: two M nuts are installed on the outside of the fixing rod, which are tightly fitted with the two side surfaces of the fixing clamp respectively. This design enhances the connection strength between the fixing rod and the fixing clamp, prevents loosening or falling off due to vibration or external force during use, and further improves the stability and safety of the overall structure.

[0010] As a preferred embodiment, the number of the mounting nuts is four and they are centrally symmetrically distributed on the rocker arm, the vibration plate is connected to the rocker arm via four mounting nuts, and the positioning core passes through the vibration plate, the brushed chassis and the sandpaper in sequence.

[0011] The beneficial effect of adopting the above-mentioned further scheme is: by distributing four mounting nuts symmetrically on the rocker arm in a central manner, the vibration plate is firmly connected to the rocker arm. This design not only improves the stability of the vibration plate, but also enables the vibration plate to transmit vibration energy more effectively, thereby improving the grinding efficiency. At the same time, the positioning core passes through the vibration plate, brushed chassis and sandpaper in sequence, thereby ensuring the accuracy and consistency of the grinding operation.

[0012] As a preferred embodiment, the adjustment component includes a chamber, an inner top wall of the chamber is fixedly connected to a micro servo motor, an output shaft of the micro servo motor is fixedly connected to a main gear, an internal rotation of the chamber is connected to a rotating rod, an outer side of the rotating rod is fixedly connected to a sub gear, an inner bottom wall of the chamber is fixedly connected to a limit frame, an internal sliding connection of the limit frame is connected to a slider, a transmission rod is fixedly connected to the top of the slider, and a positioning block is fixedly connected to the side of the slider away from the rotating rod.

[0013] The beneficial effect of adopting the above further scheme is that the adjustment component includes components such as a micro servo motor, a main gear, a sub gear, a limit frame, a slider, a transmission rod and a positioning block. This design enables the positioning core to adjust the diameter as needed to position flanges with different flange hole diameters. The precise control of the micro servo motor ensures the accuracy and stability of the adjustment, thereby improving the flexibility and applicability of the grinder.

[0014] As a preferred embodiment, the chamber is opened inside the positioning core, the chamber is located below the sandpaper, the output shaft of the micro servo motor is rotatably connected to the inner bottom wall of the chamber, and the main gear is meshed with the sub gear.

[0015] The beneficial effect of adopting the above-mentioned further scheme is that the chamber is opened inside the positioning core, below the sandpaper. This design not only saves space, but also enables the adjustment component to act more directly on the flange surface that needs to be polished. The output shaft of the micro servo motor is rotatably connected to the inner bottom wall of the chamber, ensuring the stable operation of the motor. The meshing transmission method of the main gear and the sub-gear is simple and efficient, and can respond quickly to adjustment instructions.

[0016] As a preferred embodiment, the number of the limit frames is three and they are symmetrically distributed on the outside of the rotating rod, the transmission rod passes through the sub-gear, the sub-gear is provided with an arc-shaped through hole adapted to the moving trajectory of the transmission rod, and the top of the transmission rod is fixedly connected with a limit block that fits the surface of the sub-gear, and the diameter of the limit block is slightly larger than the diameter of the transmission rod.

[0017] The beneficial effect of adopting the above-mentioned further scheme is that there are three limit frames and they are distributed symmetrically on the outside of the rotating rod. This design enhances the stability of the rotating rod and prevents deflection or shaking caused by vibration or external force. The transmission rod passes through the sub-gear and is provided with a limit block. This design not only ensures the stable movement of the transmission rod, but also prevents the transmission rod from detaching from the sub-gear during movement.

[0018] As a preferred embodiment, the limit frame is provided with a strip-shaped through hole compatible with the moving trajectory of the transmission rod, the positioning block is designed to be arc-shaped, the side surface of the positioning block away from the slider is designed to be anti-slip, and the positioning core is provided with an avoidance hole compatible with the positioning block.

[0019] The beneficial effects of adopting the above-mentioned further scheme are: the opening of the strip-shaped through hole provides space for the movement of the transmission rod in the limit frame, the positioning block is designed in an arc shape and has a non-slip surface. This design increases the friction between the positioning block and the flange, and prevents errors caused by sliding during the grinding process. At the same time, the avoidance hole opened on the positioning core enables the positioning block to be moved and adjusted more flexibly.

[0020] Compared with the prior art, the advantages and positive effects of the present invention are: First, the present invention achieves the positioning of the flange surface by accurately inserting the positioning core into the flange hole, and then uses a pneumatic or electric file tool in conjunction with a vibration plate and sandpaper to accurately grind the flange. The fixing ring, fixing rod, M nut, locking nut and other components ensure the stability and accuracy of the grinding tool. The rocker arm can be used to assist in adjusting the grinding angle, ultimately improving the grinding accuracy.

[0021] Second, when it is necessary to grind a flange whose flange hole diameter is larger than the positioning core diameter, the present invention starts the micro servo motor to drive the main gear to rotate forward, so that the sub-gear meshing with it rotates, and under the action of the arc-shaped through hole, the three transmission rods are pushed to rotate outward along the arc-shaped through hole, thereby driving the slider and the positioning block to move to the outside of the positioning core, which can be used to fix flanges with larger flange hole diameters, so that the positioning core can position flanges of different specifications, thereby improving the flexibility of the entire device.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the present invention provides a technical solution: a positioning grinder structure, comprising a pneumatic or electric file tool 1, a fixing clamp 2 is installed on the pneumatic or electric file tool 1, a locking nut 3 is installed on the pneumatic or electric file tool 1, a rocker arm 4 is installed on one side of the pneumatic or electric file tool 1, a fixing rod 5 is installed on the fixing clamp 2, an M5 nut 6 is installed on the outer side of the fixing rod 5, a positioning core 7 is fixedly connected to the other side of the fixing rod 5, a vibration plate 8 is installed at the bottom of the rocker arm 4, a mounting nut 9 is installed on the top of the vibration plate 8, a brushed chassis 10 is fixedly connected to the bottom of the vibration plate 8, and sandpaper 11 is installed at the bottom of the brushed chassis 10; An adjusting component 12 is disposed inside the positioning core 7 , and the adjusting component 12 is used for positioning a flange whose flange hole diameter is larger than the diameter of the positioning core 7 .

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the fixing clamp 2 is fixed to the pneumatic or electric file tool 1 through a locking nut 3, and one side of the pneumatic or electric file tool 1 is connected to the rocker arm 4 through an M5 nut 6; Two M5 nuts 6 are installed on the outer side of the fixing rod 5, and the two M5 nuts 6 are tightly fitted with the two side surfaces of the fixing clamp 2 respectively; There are four mounting nuts 9 which are centrally symmetrically distributed on the rocker arm 4. The vibration plate 8 is connected to the rocker arm 4 through the four mounting nuts 9. The positioning core 7 passes through the vibration plate 8, the brushed bottom plate 10 and the sandpaper 11 in sequence. The fixing method between the brushed chassis 10 and the sandpaper 11 mainly depends on the type of sandpaper 11, including but not limited to the following two types: the back of the sandpaper 11 is coated with self-adhesive glue, which can be directly pasted on the brushed chassis 10. During the pasting process, it is necessary to flatten the sandpaper 11 to avoid wavy shapes to ensure stability and effect during sanding; there are small discs or velvet structures on the back of the sandpaper 11, and these structures on the back of the sandpaper 11 can be directly fixed together with the flocking on the surface of the brushed chassis 10. This method can usually be used repeatedly.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the adjustment component 12 includes a chamber 121, the inner top wall of the chamber 121 is fixedly connected to a micro servo motor 122, the output shaft of the micro servo motor 122 is fixedly connected to a main gear 123, the interior of the chamber 121 is rotatably connected to a rotating rod 124, the outer side of the rotating rod 124 is fixedly connected to a sub gear 125, the inner bottom wall of the chamber 121 is fixedly connected to a limit frame 126, the interior of the limit frame 126 is slidably connected to a slider 127, the top of the slider 127 is fixedly connected to a transmission rod 128, and the side of the slider 127 away from the rotating rod 124 is fixedly connected to a positioning block 129.

[0028] like Figure 5 and Figure 6 As shown, the chamber 121 is opened inside the positioning core 7, and the chamber 121 is located below the sandpaper 11. The output shaft of the micro servo motor 122 is rotatably connected to the inner bottom wall of the chamber 121, and the output shaft of the micro servo motor 122 is rotatably connected to the inner bottom wall of the chamber 121, which ensures the stable operation of the micro servo motor 122 and the stability of the main gear 123 when rotating. The micro servo motor 122 is Constar 08 series, specifically model 0816N5M10-90-3.0, with a diameter of 8mm and a length in the range of 31-51mm. The main gear 123 is meshed with the sub gear 125, and the meshing transmission mode of the main gear 123 and the sub gear 125 is simple and efficient, and can quickly respond to the adjustment instructions issued by the micro servo motor 122.

[0029] like Figure 5 , Figure 6 and Figure 7 As shown, there are three limit frames 126 and they are symmetrically distributed on the outside of the rotating rod 124. The transmission rod 128 passes through the sub-gear 125. The sub-gear 125 is provided with an arc-shaped through hole adapted to the moving trajectory of the transmission rod 128. The top of the transmission rod 128 is fixedly connected with a limit block that fits the surface of the sub-gear 125. The diameter of the limit block is slightly larger than the diameter of the transmission rod 128. The opening of the arc-shaped through hole provides space for the movement of the transmission rod 128. Since the limit block fits the surface of the sub-gear 125 and the diameter of the limit block is slightly larger than the diameter of the transmission rod 128, the transmission rod 128 will not detach from the sub-gear 125 when moving, thereby ensuring the stability of the movement of the transmission rod 128.

[0030] like Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a strip through hole compatible with the moving trajectory of the transmission rod 128 is provided on the limit frame 126, and the provision of the strip through hole provides space for the transmission rod 128 to move, thereby preventing movement restriction between the limit frame 126 and the transmission rod 128, and ensuring the flexible movement of the transmission rod 128 and the slider 127. The positioning block 129 is designed in an arc shape, and the arc-shaped positioning block 129 can better fit the inner surface of the flange hole. The side surface of the positioning block 129 away from the slider 127 is designed to be anti-slip. The positioning block 129 with an anti-slip design can increase the friction between the positioning block 129 and the surface of the flange hole, thereby preventing the flange from accidentally slipping during the grinding process, thereby causing errors in grinding, and realizing precise grinding of the flange. An avoidance hole compatible with the positioning block 129 is provided on the positioning core 7, and the provision of the avoidance hole enables the positioning block 129 to flexibly enter and exit the positioning core 7, so as to facilitate the positioning and grinding of flanges with different flange hole diameters.

[0031] Working principle: By accurately inserting the positioning core 7 into the flange hole, the flange surface is positioned, and then the flange is accurately polished using a pneumatic or electric file tool 1 in conjunction with a vibration plate 8 and sandpaper 11. The fixing ring 2, fixing rod 5, M5 nut 6, locking nut 3 and other components ensure the stability and accuracy of the polishing tool. When it is necessary to polish the flange whose flange hole diameter is larger than the diameter of the positioning core 7, the micro servo motor 122 is started to drive the main gear 123 to rotate forward, so that the sub-gear 125 meshing with it rotates, and under the action of the arc through hole, the three transmission rods 128 are pushed to rotate outward along the arc through hole, thereby driving the slider 127 and The positioning block 129 moves to the outside of the positioning core 7 until the anti-slip surface of the positioning block 129 is in close contact with the flange hole, which can firmly position the flange to prevent the flange from sliding during the grinding process, thereby improving the accuracy of flange grinding. After the flange grinding is completed, the micro servo motor 122 is started to drive the main gear 123 to reverse, and under the drive of the sub-gear 125, the three transmission rods 128 are driven along the arc-shaped through hole to approach the side of the rotating rod 124. Driven by the transmission rod 128 and the slider 127, the three positioning blocks 129 move to one side of the positioning core 7, thereby releasing the positioning effect of the positioning block 129 on the flange, and the ground flange can be removed to complete the entire grinding process.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
