[0036] This embodiment takes the polishing of the concave area of ​​the steel section as a specific embodiment for explanation. The equipment platform 11 is the supporting foundation of the entire polishing equipment and is made of high-strength steel to ensure the stability and durability of the equipment during operation. The polishing chamber 13 is the core area of ​​the polishing operation and can be made of transparent or translucent materials to facilitate the operator to observe the polishing process and adjust the polishing parameters in time.

[0037] The guide positioning frame 12 is used to assist in introducing the parts to be polished toward the polishing chamber 13, and at the same time assist in positioning the non-working area of ​​the parts during polishing. The longitudinal positioning component 23 and the transverse positioning component 22 are responsible for the longitudinal and transverse positioning of the parts respectively, ensuring the stability and consistency of the parts during the polishing process.

[0038] The inner chamber bottom frame 25 serves as a supporting structure inside the polishing chamber 13 to ensure the stability and load-bearing capacity of the polishing chamber 13, and the guide carrier plate 24 is used to carry the parts to smoothly transition from the guide positioning frame 12 to the inside of the polishing chamber 13. The end support frame 26 further assists in positioning the parts, thereby maintaining the stability of the polishing operation, and the end positioning frame 27 on the end support frame 26 is used to fix the end of the parts to prevent deviation during the polishing process.

[0039] The main body of the component is mounted on the guide carrier 24, with the side of the area to be polished exposed, facing the side wing polishing bracket 28. The side wing polishing bracket 28 is connected to the polishing area. The polishing machine 29 is adjustable and slides along the side wing polishing bracket 28, so that the area to be polished of the component can be polished over a large area.

[0040] This embodiment ensures the stability and consistency of parts during the polishing process through the precise guide positioning frame 12 and the stable inner chassis 25, thereby improving the polishing efficiency; the design of the end support frame 26 and the side wing polishing bracket 28 realizes the rapid polishing of parts and improves the polishing quality. The overall design of the equipment is reasonable and easy to operate. This polishing equipment has significant advantages in improving polishing efficiency, improving polishing quality, improving working environment, and being easy to operate and maintain. It is suitable for polishing processing of concave areas of large-volume profile parts such as steel.

[0041] In one embodiment, see Figure 1 and Figure 3 As a further optimization of the above embodiment, the present embodiment is designed as follows for the specific implementation structure of the guide positioning frame 12 on the basis of the above embodiment:

[0042] The positioning frame body 21 includes a supporting frame 31, a supporting top frame 32 mounted on the top of the supporting frame 31, and a supporting bottom frame 33 arranged at the bottom of the supporting frame 31; the longitudinal positioning assembly 23 includes a fixed machine roller 36 and an adjusting machine roller 30, and both ends of the supporting bottom frame 33 are fixedly installed with fixed shaft seats 34, and a fixed roller shaft 35 is arranged on the cylinder of the fixed machine roller 36, and the shaft end of the fixed roller shaft 35 is installed in the corresponding fixed shaft seat 34; sliding lifting rails 37 are arranged on both sides of the supporting frame 31, and an adjusting shaft seat 38 is installed on the sliding lifting rails 37, and an adjusting roller shaft 39 is arranged on the cylinder of the adjusting machine roller 30, and the adjusting roller shaft 39 is installed on the adjusting shaft seat 38.

[0043] The lateral positioning assembly 22 includes a swing clamping frame 42, a vertical clamping shaft 43 arranged on the swing clamping frame 42, and a vertical clamping roller 44 installed on the vertical clamping shaft 43. The swing clamping frame 42 is provided with two and is respectively located at the left and right positions on the feeding side of the support frame 31. The upper and lower ends of the swing clamping frame 42 are respectively installed on the support top frame 32 and the support bottom frame 33 through the steering mechanism 41.

[0044] The main body of the positioning frame body 21 is composed of a support frame 31, a support top frame 32 and a support bottom frame 33. The support frame 31 is used as the main structure to provide sufficient rigidity and stability; the support top frame 32 and the support bottom frame 33 are located at the top and bottom of the support frame 31 respectively. The longitudinal positioning assembly 23 includes a fixed machine roller 36 and an adjusting machine roller 30, which are used to position the parts in the longitudinal direction. Among them, a driving device such as a cylinder or an electric push rod is set on the top of the support top frame 32 to drive the adjusting shaft seat 38 to slide up and down along the sliding lifting rail 37, and adjust the height of the adjusting machine roller 30 to adapt to parts of different thicknesses; in the part introduction stage, the fixed machine roller 36 at the bottom plays an auxiliary role in bearing the force of the parts, and assists in introducing the parts to the guide carrier 24 on the rear side. In the polishing preparation stage, the adjusting machine roller 30 moves down along the sliding lifting rail 37, and the fixed machine roller 36 and the adjusting machine roller 30 cooperate with each other to clamp and position the parts. The guide carrier 24 is composed of swing clamping frames 42 on both sides. The swing clamping frame 42 is installed through the steering mechanism 41. The driving end of the steering mechanism 41 can be connected to a driving tool such as a hydraulic cylinder, a pneumatic cylinder or an electric push rod to drive the swing clamping frame 42 to move. The vertical clamping roller 44 is installed on the vertical clamping shaft 43 to clamp the side of the component to complete the positioning of the side area.

[0045] This embodiment ensures the stability and accuracy of the parts during the polishing process, thereby improving the polishing accuracy. The height of the adjusting roller 30 is adjustable, and the clamping spacing of the swing clamping frames 42 on both sides is also adjustable, so that the polishing equipment can adapt to parts of different sizes and shapes, improving the versatility and flexibility of the equipment.

[0046] In one embodiment, see Figure 2 and Figure 4 As a further optimization of the above embodiment, the present embodiment is designed as follows for the specific implementation structure of the guide positioning frame 12 on the basis of the above embodiment:

[0047] The end support frame 26 includes a support base 111 mounted on the equipment machine 11, a support frame 112 installed on the support base 111, and a vertical substrate 114 arranged on the support frame 112, the support frame 112 is provided with a horizontal fine-tuning module 113, and the vertical substrate 114 is slidably installed on the horizontal fine-tuning module 113; the end positioning frame 27 includes a pressing frame 116 and a pressing substrate 117 installed at the bottom of the pressing frame 116; the vertical substrate 114 is installed with a vertical fine-tuning module 115, and the pressing frame 116 is slidably installed on the vertical fine-tuning module 115.

[0048] The support base 111 is firmly mounted on the equipment platform 11 as the basic structure of the end support frame 26. The horizontal fine-tuning module 113 is set on the support frame 112, usually composed of a precision lead screw, a guide rail and a drive motor, etc., which can achieve a small adjustment of the vertical substrate 114 in the horizontal direction. The vertical fine-tuning module 115 is installed on the vertical substrate 114 to achieve a small adjustment of the pressing frame 116 in the vertical direction to ensure the precise position of the parts during the polishing process. During the polishing positioning process, the parameters of the horizontal fine-tuning module 113 and the vertical fine-tuning module 115 can be adjusted as needed to achieve the best polishing effect.

[0049] In one case of this embodiment, see Figure 4 and Figure 5 , for the press-fit positioning method of parts such as steel sections, this embodiment is designed as follows;

[0050] Positioning cylinders 51 are installed at the four corners of the pressing substrate 117, and a pressing suction cup 52 is provided at the bottom of the positioning cylinder 51; a telescopic support rod 54 is provided at the bottom end of the pressing frame 116, a contact head 55 is provided at one end of the telescopic support rod 54, and a pressure sensor 53 is externally installed at the other end of the telescopic support rod 54.

[0051] The positioning cylinder 51 is a pneumatic component, which usually includes a cylinder body and a piston rod. The extension and retraction of the piston rod are achieved by the drive of compressed air. In the present invention, the positioning cylinder 51 is installed at the four corners of the pressing substrate 117 to ensure all-round support and positioning of the ends of the components. The pressing suction cup 52 is arranged at the bottom of the positioning cylinder 51, which is a device that uses the negative pressure principle to adsorb objects. When the piston rod of the positioning cylinder 51 is extended, the pressing suction cup 52 is in close contact with the end of the component, and generates suction through the internal negative pressure system to firmly adsorb the component on the pressing substrate 117, thereby achieving precise positioning and stable support of the component.

[0052] The contact head 55 is used to monitor the position of the parts, and the pressure sensor 53 is externally installed at the other end of the telescopic support rod 54, and is used to monitor the contact pressure between the contact head 55 and the parts in real time. After the parts come into contact with the contact head 55, the pressure sensor 53 senses the pressure change and immediately sends out a relevant signal to stop driving the transmission movement of the parts, and immediately drives the pressing frame 116 to move downward to complete the positioning of the parts by pressing the substrate 117, thereby ensuring the accuracy of the positioning of the parts.

[0053] In one embodiment, see Figure 2 , Figure 6 , Figure 7 and Figure 8As a further optimization of the above embodiment, the present embodiment is designed as follows for the specific implementation structure of the guide positioning frame 12 on the basis of the above embodiment:

[0054] The flank polishing bracket 28 includes a polishing transmission platform 61 and a polishing motion track 62 arranged on the polishing transmission platform 61. The polishing transmission platform 61 is mounted on both sides of the inner compartment of the polishing compartment 13. The polishing machine 29 is slidably mounted on the polishing motion track 62. The polishing machine 29 includes a polishing member base plate 71 mounted on the slide rail of the polishing motion track 62, a support frame plate 72 mounted on the polishing member base plate 71, and a polishing brush 73 arranged on the support frame plate 72. The polishing machine 29 also includes a solvent spraying member 74 and a support frame 75. The solvent spraying member 74 and the support frame 75 are respectively provided with the upper and lower parts of the polishing brush 73. The polishing brush 73 includes a mounting end 81 mounted on the support frame plate 72, a polishing base plate 82 mounted on the mounting end 81, and a polishing surface 83 arranged on the polishing base plate 82.

[0055] The polishing transmission platform 61 is firmly mounted on both sides of the inner chamber of the polishing chamber 13 , and the polishing motion track 62 extends along the length direction of the polishing transmission platform 61 , ensuring that the polishing machine 29 can slide smoothly along a predetermined path.

[0056] The polishing machine 29 is the core component of the entire polishing equipment, which is responsible for directly polishing the machine tool parts. The polishing member base plate 71 is the basic component of the polishing machine 29, which is connected to the polishing motion track 62 through a slide rail, and the support frame plate 72 is installed on the polishing member base plate 71 to support and fix the polishing brush 73. The polishing brush 73 is a direct working tool, and its polishing surface 83 is embedded in the concave area of ​​the part, and the surface defects are removed by friction to achieve the purpose of polishing.

[0057] In one case of this embodiment, see Fig. 9 The support base frame 75 includes a side edge support plate 92 and a mounting plate 91 arranged on the side edge support plate 92. The mounting plate 91 is installed on the bottom edge of the support frame plate 72 through a locking bolt 93. There is a gap between the side edge support plate 92 and the support frame plate 72. A plurality of edge frames 94 are also arranged on the side edge support plate 92, and gaskets 95 are arranged on the edge frames 94.

[0058] In the further design of the polishing equipment, the support frame 75 is mainly composed of a side support plate 92 and a mounting plate 91, and the mounting plate 91 firmly mounts the side support plate 92 to the bottom edge of the support frame plate 72 through a locking bolt 93. The side support plate 92 is supported on the bottom edge of the component, and its shape and size are designed according to the specific requirements of the machine tool components, and has sufficient strength and rigidity to withstand various forces and vibrations generated during the polishing process.

[0059] A plurality of edge brackets 94 are also provided on the side edge support plate 92, and gaskets 95 are provided on the edge brackets 94. The gaskets 95 are usually made of wear-resistant and corrosion-resistant materials to increase the friction and stability between the edge brackets 94 and the machine tool parts. At the same time, the gaskets 95 can also play a buffering role, reducing the direct contact between the machine tool parts and the edge brackets 94, thereby extending the service life of the equipment.

[0060] In one case of this embodiment, see Figure 1 , Fig.10 and Fig.11 The solvent spraying mechanism 74 includes a head-up plate 101 mounted on the polishing substrate 71 and a plurality of liquid injectors 102 arranged on the head-up plate 101. A liquid through port 103 is arranged on the top of the liquid injector 102, and a spreading head 104 is arranged on the bottom of the liquid injector 102. A liquid guide step 105 is also arranged on the head-up plate 101. The liquid guide step 105 is arranged obliquely above the polishing substrate 82, and a plurality of liquid guide grooves 84 are arranged on the polishing surface 83.

[0061] As a key component in the polishing equipment, the solvent spraying mechanism 74 is designed to ensure that the polishing solvent can be sprayed evenly and accurately onto the polishing surface 83 and the surface of the machine tool parts, thereby optimizing the polishing effect.

[0062] The head plate 101 is fixedly mounted on the polishing substrate 71 by appropriate connection methods (such as bolts, welding, etc.) to ensure the stability and reliability of the solvent spraying mechanism 74 during the polishing process. The solution access device 14 is provided with a liquid storage container and a delivery pipeline, and the injectors 102 are evenly distributed on the head plate 101, which are used to extract the polishing solvent from the liquid storage container and spray it onto the polishing surface 83 and the surface of the machine tool parts. The top of each injector 102 is provided with a liquid port 103 for connecting the liquid storage container and the delivery pipeline, and the bottom of the injector 102 is provided with a spreading head 104. In order to further improve the uniformity and accuracy of the solvent spraying, a liquid guide step 105 is also provided on the head plate 101. The liquid guide step 105 is located obliquely above the polishing substrate 82, and its shape and height are accurately calculated to ensure that the polishing solvent sprayed from the injector 102 can flow smoothly to the polishing surface 83 along the liquid guide step 105. The design of the liquid guiding step 105 not only helps to reduce the waste and splashing of solvent, but also improves the utilization rate of solvent and the polishing effect.

[0063] In addition, a number of liquid guide grooves 84 are provided on the polishing surface 83. The liquid guide grooves 84 are tiny grooves used to guide and collect the polishing solvent. They are evenly distributed on the polishing surface 83 and cooperate with the liquid guide steps 105 to ensure that the polishing solvent can evenly cover the entire polishing surface 83. The design of the liquid guide grooves 84 helps to reduce the accumulation and retention of the solvent on the polishing surface 83. The solvent flows along the liquid guide steps 105 and the liquid guide grooves 84, and fully contacts the polishing surface 83 and the surface of the machine tool parts, which plays a role in lubricating the polishing surface 83, accelerating the polishing process and reducing the heat generated by friction. At the same time, the uniform coverage of the solvent also helps to improve the uniformity and consistency of the polishing effect, and reduce polishing errors and rework rates.

[0064] In addition, there is a certain gap between the side edge support plate 92 and the support bracket plate 72. The gap is located directly below the polishing surface 83. Together with the downward flow of the polishing solvent, it can help take away heat and polishing debris, thereby avoiding unnecessary damage to parts caused by excessive friction heat and polishing vibrations, thereby extending the operating quality of the parts and improving the service life of the polishing surface 83.

[0065] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

[0066] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
