DETAILED DESCRIPTION

[0016] The technical schemes in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application (for the convenience of description and understanding, the embodiments in the present application are described below as follows Figure 2above is described). All other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of the present application.

[0017] Please refer to Figures 1-3 The application provides a technical scheme: a piston rod rapid polishing device of a heavy-duty bidirectional buffer, which comprises a base support frame 6, the upper end of the base support frame 6 is provided with a workbench 14, the upper surface of the workbench 14 is provided with a clamping group and a rotary drive group at both ends, the clamping group and the rotary drive group are correspondingly arranged, and a piston rod to be processed is arranged between the clamping group and the rotary drive group.

[0018] The base support frame 6 provides a firm support platform, which ensures that the components thereon can stably operate.

[0019] The upper surface of the workbench 14 is flat and firm, which provides mounting positions for the clamping group, the rotary drive group and other auxiliary components, and ensures that the above-mentioned components can be accurately aligned and operated on the same horizontal plane.

[0020] The clamping group is located at one end of the workbench 14 and is mainly used for fixing the piston rod to be processed, so as to ensure that the piston rod can be stably installed.

[0021] The rotary drive group corresponds to the clamping group and is used for driving the piston rod to rotate, so that the piston rod can uniformly rotate in the polishing process, the abrasive belt can cover the entire circumferential surface, and comprehensive polishing is realized.

[0022] The upper surface of the workbench 14 is further provided with a moving group, the moving group is slidably connected with a mounting bracket 2, and the mounting bracket 2 is provided with an abrasive belt driving group.

[0023] The moving group is a component for realizing the movement of the abrasive belt driving group along the length direction of the piston rod, which ensures that the abrasive belt driving group can stably and accurately move along the set path.

[0024] The abrasive belt driving group comprises a telescopic air cylinder 1, an extension rod 7, a polishing abrasive belt 8 and an abrasive belt connecting frame 12, the telescopic end of the telescopic air cylinder 1 is connected with the extension rod 7, the end of the extension rod 7 is connected with the abrasive belt connecting frame 12, and the polishing abrasive belt 8 for covering the piston rod to be processed is arranged between the abrasive belt connecting frames 12.

[0025] The abrasive belt driving group is composed of the telescopic air cylinder 1, the extension rod 7, the polishing abrasive belt 8 and the abrasive belt connecting frame 12, and the components work cooperatively to realize effective polishing of the piston rod.

[0026] The telescopic air cylinder 1 is the power source for adjusting the contact pressure between the polishing belt 8 and the piston rod. By precisely controlling the telescopic amount of the telescopic air cylinder 1, it can ensure that the polishing belt 8 applies appropriate pressure during polishing, neither damaging the workpiece surface due to excessive pressure, nor resulting in poor polishing effect due to insufficient pressure.

[0027] The sand belt connecting frame 12 is used to support and guide the polishing belt 8, and is installed at both ends of the lengthened rod 7 to maintain the appropriate tension of the sand belt. The sand belt connecting frame 12 is clamped in place, which facilitates the operator to replace the worn-out sand belt regularly during polishing.

[0028] Further, the clamping group includes a connecting bracket seat 10, a jacking cylinder 15 and a jacking end, the jacking cylinder 15 is installed on the connecting bracket seat 10, and the jacking end is installed at the end of the jacking cylinder 15.

[0029] The clamping group is used to fix the piston rod to be processed, ensuring that the piston rod can remain stable during polishing and is not affected by external forces. The connecting bracket seat 10 is the basic structure of the clamping group, which provides a stable mounting platform, and the jacking cylinder 15 is the power source of the clamping group. The jacking cylinder 15 provides the necessary clamping force to firmly fix the piston rod in place, and the jacking end directly acts on the end of the piston rod. In order to protect the workpiece and avoid damage during clamping, the jacking end is usually wrapped with a soft material (such as rubber or polyurethane) around a metal core, which can provide sufficient friction to fix the piston rod without scratching its surface. The connecting bracket seat 10 provides a fixed mounting position for the jacking cylinder 15, ensuring that the cylinder can generate stable thrust in the predetermined direction. The jacking cylinder 15 converts the power from compressed air into mechanical force through its telescopic movement, pushing the jacking end closer to the piston rod, and the jacking end directly contacts the piston rod. Under the clamping force provided by the cylinder, the piston rod remains stationary during the entire polishing process.

[0030] In use, the jacking cylinder 15 pushes the jacking end to move forward until it tightly fits one end of the piston rod; at this time, the piston rod is firmly fixed between the rotary drive group and the clamping group, and the polishing operation begins.

[0031] Further, the rotary drive group includes a connecting bracket seat 10, a rotary drive 9 and an axle top seat, the rotary drive 9 is arranged at the upper end of the connecting bracket seat 10, and the axle top seat is connected to the output end of the rotary drive 9.

[0032] The rotary drive group is used to drive the piston rod to rotate, ensuring that the piston rod can rotate uniformly during polishing, thereby achieving comprehensive and consistent surface treatment.

[0033] The connecting bracket base 10 provides a stable mounting platform to withstand the torque generated during rotation.

[0034] The shaft top seat is located at the output end of the rotary drive 9, directly contacting and supporting one end of the piston rod; ensuring that the piston rod maintains concentricity during rotation, avoiding uneven polishing due to eccentricity.

[0035] The shaft top seat is directly in contact with one end of the piston rod, driven by the torque provided by the rotary drive 9 to rotate the piston rod.

[0036] Further, the lower end of the connecting bracket base 10 is connected with a telescopic adjusting structure, which includes a lifting cylinder 11 and a base support plate, the telescopic end of the lifting cylinder 11 is connected with the base support plate, and the base support plate is connected with the connecting bracket base 10.

[0037] The lifting cylinder 11 provides linear motion in the vertical direction to meet the processing of piston rods of different diameters.

[0038] In use, the telescopic end of the lifting cylinder 11 is connected with the base support plate, and the up and down movement of the base support plate and the connecting bracket base 10 connected thereto is realized through a pneumatic control system.

[0039] Further, the workbench 14 is provided with a guide rod 16, and the guide rod 16 passes through the base support plate.

[0040] The guide rod 16 is used to ensure that the base support plate maintains vertical motion during lifting; preventing it from tilting or deviating during movement, ensuring that the clamping group and the rotary drive group can adjust the height stably and accurately.

[0041] Further, the moving group includes a displacement adjusting cylinder 5, a sliding rail 3 and a sliding block 13, the sliding rail 3 and the sliding block 13 are slidingly connected, the bottom plate of the mounting bracket 2 is connected with the sliding block 13, and the telescopic end of the displacement adjusting cylinder 5 is connected with one side of the mounting bracket 2.

[0042] The sliding rail 3 provides a stable guide path for the sliding block 13, ensuring that the mounting bracket 2 can move smoothly on the sliding rail, and the bottom plate of the mounting bracket 2 is firmly combined with the sliding block 13 through mechanical connection (such as bolts), so that the mounting bracket 2 can move along the sliding rail 3 together with the sliding block 13, and the telescopic end of the displacement adjusting cylinder 5 is connected with one side of the mounting bracket 2 through a connecting piece, and the advancing and retreating action of the mounting bracket 2 is realized through a pneumatic control system.

[0043] Further, the upper surface of the workbench 14 is provided with a cylinder mounting seat 4, and the cylinder mounting seat 4 is connected with the displacement adjusting cylinder 5.

[0044] In use: Place the piston rod to be processed horizontally between the clamping assembly and the rotary drive assembly, ensuring that one end is close to the clamping assembly and the other end is in contact with the shaft top seat in the rotary drive assembly. At this time, the clamping cylinder 15 operates, pushing the clamping end forward until it tightly fits against one end of the piston rod and securely fixes it. The piston rod is now firmly clamped between the clamping assembly and the rotary drive assembly. If it is necessary to accommodate piston rods of different diameters, activate the lifting cylinder 11 and set the appropriate height value through the control system. The base support plate will rise or fall smoothly under the guidance of the guide rod 16 until the required processing height is reached. Activate the rotary drive component 9 in the rotary drive assembly and set the appropriate speed as needed. The torque provided by the rotary drive component will be transmitted to the piston rod through the shaft top seat, causing it to begin rotating evenly. Control the displacement adjusting cylinder 5 to move the mounting bracket 2 and the sanding belt drive assembly on it along the slide rail 3 to the starting position. The telescopic cylinder 1 adjusts the appropriate grinding pressure to ensure that the grinding belt 8 fits tightly against the piston rod surface. As the piston rod continues to rotate and the grinding belt drive group moves along the slide rail 3, the entire piston rod surface will be uniformly ground.
