Description

Technical Field

[0001] This utility model relates to the field of polishing technology, and in particular to a polishing machine for the inner hole of a hydraulic cylinder. Background Technology

[0002] A hydraulic cylinder inner bore polishing machine is a device specifically designed for polishing the inner walls of hydraulic cylinders.

[0003] Traditional polishing equipment consists of a motor, a connecting rod, and a polishing wheel. The connecting rod connects the motor and the polishing wheel, keeping the polishing wheel away from the motor to prevent it from being unable to insert into the cylinder's inner bore. When polishing the cylinder's inner bore, the cylinder is first moved to one side of the polishing wheel, allowing the polishing wheel to penetrate the cylinder. The polishing wheel then polishes the inner bore. However, during the process of moving the cylinder in and out of the polishing chamber, there is a possibility of the cylinder colliding with the polishing wheel. If the polishing wheel is subjected to prolonged collisions, the connecting rod may bend to one side. Therefore, this solution proposes a cylinder inner bore polishing machine to address the above problems. Utility Model Content

[0035] 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.

[0036] This utility model provides, for example Figure 1-4 Shown:

[0037] Example 1:

[0038] A hydraulic cylinder inner bore polishing machine, comprising:

[0039] Processing table 1;

[0040] A polishing assembly for polishing the inner bore of a hydraulic cylinder, the polishing assembly including a connecting rod 3 disposed on the top of the processing table 1;

[0041] Support component 5 includes a mounting base 501 set on one side of the processing table 1. A support arm 502 for supporting the connecting rod 3 is fixedly connected to one side of the mounting base 501. A positioning clamp 503 for limiting the swaying of the connecting rod 3 is set at the top of the support arm 502.

[0042] The connecting component 6 is located at the connection between the support arm 502 and the positioning clamp 503, and is used to fix the support arm 502 and the positioning clamp 503.

[0043] It should be noted that the mounting base 501 is fixedly connected to the processing table 1 by multiple bolts, and the support arm 502 is fixedly connected to one side of the mounting base 501 by welding. An arc-shaped groove is opened at the top of the support arm 502, and the connecting rod 3 is inserted into the inside of the arc-shaped groove. The distance between the connecting rod 3 and the support arm 502 is 0.3 to 0.4 cm. The distance between the positioning clamp 503 and the connecting rod 3 is the same as the distance between the connecting rod 3 and the arc-shaped groove, so as to avoid friction between the connecting rod 3 and the support arm 502 and the positioning clamp 503 when the connecting rod 3 rotates. In use, the mounting base 501 is used to fix the support arm 502 to the processing table 1, so that the connecting rod 3 is inserted into the top of the support arm 502. The connecting assembly 6 is used to fix the positioning clamp 503 to the support arm 502, and the positioning clamp 503 and the support arm 502 restrict the connection, so that one end of the connecting rod 3 cannot be bent.

[0044] Specifically, the polishing components also include:

[0045] Motor 2 is fixedly connected to the top of the processing table 1, and connecting rod 3 is fixedly connected to the output end of motor 2;

[0046] Polishing wheel 4 is located at the end of connecting rod 3 away from motor 2.

[0047] It should be noted that the motor 2 is an existing servo motor. When in use, the oil cylinder is first moved to one side of the polishing wheel 4 and the motor 2 is turned on. The motor 2 drives the connecting rod 3 and the polishing wheel 4 to rotate. Finally, the oil cylinder is moved so that the polishing wheel 4 passes into the inner hole of the oil cylinder. The inner hole of the oil cylinder is polished by the rotating polishing wheel 4.

[0048] Specifically, connection component 6 includes:

[0049] The first connecting ear 601 is fixedly connected to the top of the support arm 502;

[0050] The second connecting ear 602 is fixedly connected to the bottom of the positioning clamp 503;

[0051] A connecting block 605 is fixedly connected to the top of the first connecting ear 601. A connecting groove 606 is provided at the bottom of the second connecting ear 602, and the connecting block 605 is inserted into the inside of the connecting groove 606.

[0052] A limiting component is provided at the connection between the connecting block 605 and the connecting groove 606. The limiting component is used to restrict the movement of the limiting block 604.

[0053] It should be noted that there are two first connecting ears 601 and two second connecting ears 602, which are fixedly connected to the front and back of the support arm 502 and the positioning clamp 503, respectively. A connecting groove 606 is provided to fit the connecting block 605. When it is necessary to fix the support arm 502 and the positioning clamp 503, first move the positioning clamp 503 to the top of the support arm 502, align the connecting block 605 on the first connecting ear 601 with the connecting groove 606 on the second connecting ear 602, and then move the positioning clamp 503 so that the second connecting ear 602 is fitted onto the connecting block 605 through the connecting groove 606. The connecting block 605 is then fixed inside the connecting groove 606 by the limiting member.

[0054] Specifically, the limiting components include:

[0055] A limiting hole 603 is provided in the middle of the connecting block 605;

[0056] The limiting block 604 is inserted into the inner wall of one side of the connecting groove 606 and is inserted into the interior of the limiting hole 603. A moving part 7 for moving the position of the limiting block 604 is provided on one side of the limiting block 604.

[0057] It should be noted that the limiting hole 603 is adapted to the limiting block 604, so that the limiting block 604 can pass through the interior of the limiting hole 603. When the connecting block 605 is fixed inside the connecting groove 606, the limiting block 604 is inserted into the interior of the limiting hole 603 on the connecting block 605, and at the same time, the limiting block 604 is inserted into the inner wall on one side of the connecting groove 606. The limiting block 604 restricts the direction of movement, thereby restricting the connecting block 605 from moving out of the connecting groove 606.

[0058] Example 2:

[0059] The moving part 7 is applied to the polishing machine in Embodiment 1;

[0060] Specifically, the mobile unit 7 includes:

[0061] Drive block 701, which is fixedly connected to one end of limiting block 604;

[0062] Spring 705 is located on one side of drive block 701.

[0063] It should be noted that the spring 705 is located on the side of the driving block 701 away from the limiting block 604. The spring 705 pushes the driving block 701 toward the limiting block 604. Thus, when the limiting block 604 and the driving block 701 move away from the limiting hole 603 due to the vibration of the polishing machine, the spring 705 pushes the driving block 701 and the limiting block 604 to prevent the limiting block 604 from moving out of the limiting hole 603.

[0064] Specifically, the mobile unit 7 also includes:

[0065] The through-hole block 703 is fixedly connected to the top of the drive block 701;

[0066] Push block 704 is fixedly connected to the top of the through block 703.

[0067] Specifically, a cavity 706 is provided in the middle of the second connecting ear 602, and the driving block 701 and the spring 705 are both inserted and connected inside the cavity 706. A through hole 702 is provided on the inner wall of the top of the cavity 706, and the through block 703 is inserted and connected inside the through hole 702.

[0068] It should be noted that the cavity 706 is adapted to the drive block 701, allowing the drive block 701 to slide inside the cavity 706. The through hole 702 and the through block 703 are used to connect the drive block 701 inside the cavity 706 and the push block 704 outside the cavity 706. When the position of the limiting block 604 needs to be moved, the push block 704 directly drives the through block 703 and the drive block 701 to move, and the drive block 701 drives the limiting block 604 to move.

[0069] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
