Description

Technical Field

[0001] This utility model relates to the field of grinding machinery technology, specifically a semi-automatic polymer cylindrical rubber fine grinding device. Background Technology

[0002] Currently, traditional industries use grinding wheels for grinding the outer diameter of polymer cylindrical rubber. This method has the drawbacks of grinding elastic materials. During traditional grinding, the elastic deformation of the rubber causes uneven contact between the grinding wheel and the product, resulting in vibration patterns on the surface, excessive local pressure, and material tearing or burning. It also lacks compatibility, requiring the entire grinding wheel to be replaced when changing workpieces with different precision requirements, which is costly, causes long downtime, requires multiple machines for rough grinding / fine grinding, and results in low production line space utilization. Furthermore, the grinding wheel cannot be adjusted in real time after local wear, leading to an increased scrap rate. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, this utility model provides a semi-automatic polymer cylindrical rubber fine grinding device, which solves the problem that the existing rubber elasticity causes grinding patterns and cannot perform high-precision grinding.

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.

[0014] like Figure 1 and Figure 4 As shown A semi-automatic polymer cylindrical rubber fine grinding device includes a fixed base 1, an X-axis moving platform 2 fixedly mounted on the upper side of the fixed base 1, a clamp 3 mounted on the X-axis moving platform 2, a clamping cylinder 4 mounted on the clamp 3, a spindle servo motor 5 mounted on the clamp 3, and a Y-axis moving platform 6 mounted on the fixed base 1 and located on one side of the X-axis moving platform 2. The device is characterized in that: a sanding belt adjusting clamping mechanism 7 is mounted on the side of the Y-axis moving platform 6 closest to the X-axis moving platform 2, and a sanding belt 8 is fixedly mounted on one side of the sanding belt adjusting clamping mechanism 7; both the X-axis moving platform 2 and the Y-axis moving platform 6 are guided by high-precision hard steel rails and driven by high-precision ball screws to achieve micron-level displacement.

[0015] The sanding belt adjusting and clamping mechanism 7 includes a sliding seat 71 mounted on the Y-axis moving platform 6. An adjusting screw 72, a high-precision ball screw, is threadedly connected to the side of the sliding seat 71 closest to the X-axis moving platform 2. An adjusting moving block 73 is threadedly connected to the adjusting screw 72. A moving guide rail 74, a HIWIN precision linear guide rail, is fixedly mounted on the moving guide rail 74. A fixed sanding belt clamp 75 and a moving sanding belt clamp 76 are respectively mounted on the moving guide rail 74. The sanding belt 8 is fixedly positioned between the fixed sanding belt clamp 75 and the moving sanding belt clamp 76. A tension spring 77 is fixedly mounted between the moving sanding belt clamp 76 and the end of the moving guide rail 74. The adjusting screw 72 pushes the moving block 73, changing the contact position of the sanding belt 8 to avoid single-point wear. The tension spring 77 automatically maintains the sanding belt tension.

[0016] The X-axis moving platform 2 has an X-axis transverse servo motor 21 at one end, and the Y-axis moving platform 6 has a Y-axis longitudinal servo motor 61 at one end; both are Mitsubishi servo motors. The X-axis moving platform 2 and the Y-axis moving platform 6 are based on the structure of a grinding machine. Modifications can be made to the existing grinding machine structure.

[0020] The X-axis horizontal servo motor 21, Y-axis vertical servo motor 61, clamping cylinder 4, and spindle servo motor 5 are controlled by a PLC. The Mitsubishi PLC coordinates the clamping cylinder 4, spindle servo motor 5, X-axis horizontal servo motor 21, and Y-axis vertical servo motor 61, which are positioned via magnetic induction switches to ensure the accuracy of the grinding path.

[0021] This invention achieves flexible grinding through an adjustable abrasive belt mechanism 7, solving the problem of insufficient surface finish caused by the elasticity of rubber. It reuses the existing high-precision hardened steel rails and servo system of the grinding machine to ensure micron-level feed, and does not require changes to the original grinding wheel structure; the original grinding wheel assembly 10 can still be retained, making modifications easy. Changing the abrasive belt 8 to different mesh sizes can adapt to various precision requirements.

[0022] The workflow of this utility model is as follows: 1. Manual feeding and clamping Place the cylindrical rubber product into clamp 3; Press the control button → clamping cylinder 4 activates → securely fixes the product.

[0023] 2. Sanding belt installation and tensioning Insert the sanding belt 8 into both ends respectively: Fixed sanding belt clamp 75 (non-movable end); Mobile sanding belt clamp 76 (elastic end); Tensioning spring 77 (MISUMI high elasticity spring) automatically tightens the abrasive belt → ensures stable grinding tension.

[0024] 3. Adjusting the position of the sanding belt Manually rotate the adjustment handwheel 78 to drive the adjustment screw 72 (high-precision ball screw); The adjusting moving block 73 is driven to slide along the moving guide rail 74 (HIWIN linear guide rail); The position of the movable sanding belt clamp 76 is changed → the contact area between the sanding belt 8 and the product is adjusted; Objective: To avoid repeated grinding in the same area (to solve the problem of localized wear of the abrasive belt).

[0025] 4. Start automatic grinding Launch from Control Panel: Spindle servo motor 5 → drives the product to rotate at high speed; Automatic grinding mode → Mitsubishi PLC issues command; Critical servo system linkage: X-axis transverse servo motor 21 → controls the transverse feed of the product; Y-axis longitudinal servo motor 61 → controls the longitudinal feed of the sanding belt; Displacement accuracy guaranteed: Rigid steel rail guide (originally component No. 10); Micron-level feed (the grinding machine comes with a precision ball screw).

[0026] 5. Core actions in the grinding process The abrasive belt 8 grinds the outer diameter of a rotating rubber product using a flexible contact method; X / Y axis platform coordinated motion → product rotates and translates simultaneously → achieves uniform grinding of the entire outer circle; Control system monitoring: Magnetic induction switch for real-time positioning; PLC dynamically adjusts the servo motor feed rate.

[0027] 6. Complete fine grinding PLC determines grinding is complete → automatically stops all motors; Manual unloading → Achieving a high-gloss surface.
