Description

Technical Field

[0001] This utility model relates to the field of polishing, and in particular to an inner wall polishing device for hydraulic cylinder processing. Background Technology

[0002] In the machining of hydraulic cylinders, internal wall polishing is a critical process, and its quality directly affects the performance and service life of the hydraulic cylinder. The internal wall polishing device, as the core equipment for realizing this process, plays a vital role in the entire machining process.

[0003] Currently, in actual production, existing hydraulic cylinder inner wall polishing devices usually adopt relatively simple positioning and polishing methods. During positioning, they mostly rely on manual operation or simple clamps to roughly fix the hydraulic cylinder in the processing position.

[0004] However, during slow polishing, the hydraulic cylinder is prone to shaking, which prevents the polishing tool from making full and uniform contact with the inner wall. This results in inconsistent surface roughness of the polished inner wall, which seriously affects the sealing performance and overall quality of the hydraulic cylinder. To address this issue, an inner wall polishing device for hydraulic cylinder processing is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an inner wall polishing device for hydraulic cylinder processing, which aims to solve the problem that the existing technology cannot make full and uniform contact with the inner wall.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an inner wall polishing device for hydraulic cylinder processing, comprising a base plate, a processing table fixedly connected to the top of the base plate, a fixing plate fixedly connected to the outer wall of the top of the base plate, a linear motor fixedly connected to the top of the fixing plate, a first movable plate slidably connected to the outer wall of the fixing plate, the output end of the linear motor fixedly connected to the top of the first movable plate, a grinding machine fixedly connected to the outer wall of the first movable plate, a polishing tool fixedly connected to the output end of the grinding machine, and a positioning mechanism provided on the top of the base plate;

[0007] The positioning mechanism includes a threaded plate, the bottom of which is slidably connected to the top of the base plate. A first clamping plate is fixedly connected to the outer wall of the threaded plate. A vertical plate is fixedly connected to the top of the processing table. A gear is rotatably connected to the outer wall of the vertical plate. A second screw is threadedly connected to the inner ring of the gear. A second clamping plate is fixedly connected to one end of the second screw.

[0008] As a further description of the above technical solution: a dual-head motor is fixedly connected to the outer wall of the top of the base plate, and the output end of the dual-head motor is fixedly connected to a first screw through a coupling. The outer wall of the first screw is threadedly connected to the inner wall of the threaded plate.

[0009] As a further description of the above technical solution: a connecting rod is fixedly connected to the outer wall of the threaded plate, and a toothed plate is fixedly connected to the outer wall of the connecting rod, with the outer wall of the toothed plate meshing with the outer wall of the gear.

[0010] As a further description of the above technical solution: the connecting rod has an irregular shape.

[0011] As a further description of the above technical solution: a limiting component is provided above the processing table. The limiting component includes a limiting plate and a limiting rod. The limiting plate is fixedly connected to the other end of the second screw. The outer wall of the limiting plate is fixedly connected to the limiting rod. The outer wall of the limiting rod is slidably connected to the inner wall of the vertical plate.

[0012] As a further description of the above technical solution: the clamping surfaces of the first clamping plate and the second clamping plate are both flexible.

[0013] As a further description of the above technical solution: the top of the polishing tool is provided with an auxiliary mechanism, the auxiliary mechanism including a second movable plate, the bottom of the second movable plate being slidably connected to the top of the polishing tool, the top of the second movable plate being hinged to a hinge plate, the hinge plate being hinged to a cleaning plate, and the outer wall of the cleaning plate being slidably connected to the outer wall of the polishing tool.

[0014] As a further description of the above technical solution: a control plate is fixedly connected to the top of the second movable plate, and an electric cylinder is fixedly connected to the top of the polishing tool. The output end of the electric cylinder is fixedly connected to the outer wall of the control plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, a double-headed motor drives the first screw, which in turn moves the threaded plate and causes the first clamping plate to move. At the same time, the threaded plate drives the connecting rod and the toothed plate, and the toothed plate drives the gear to rotate, which in turn drives the second screw to move the second clamping plate. This achieves positioning and stable clamping of the hydraulic cylinder. During slow polishing, it can effectively prevent the hydraulic cylinder from shaking and ensure that the polishing tool has full and uniform contact with the inner wall.

[0017] 2. In this utility model, the auxiliary mechanism can be started at any time during the polishing process. The second movable plate is controlled by an electric cylinder, which drives the hinge plate and the cleaning plate to move. This can clean up the debris in time during the polishing process, ensuring that the polishing tool always works on a clean surface and reducing the number of times polishing is interrupted due to cleaning.

[0024] 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.

[0025] Reference Figure 1 - Figure 3This utility model provides an embodiment of an inner wall polishing device for hydraulic cylinder processing, comprising a base plate 1, a processing table 2 fixedly connected to the top of the base plate 1 for placing the hydraulic cylinder, a fixing plate 3 fixedly connected to the outer wall of the top of the base plate 1, a linear motor 4 fixedly connected to the top of the fixing plate 3 for mounting the linear motor 4, a first movable plate 5 slidably connected to the outer wall of the fixing plate 3, the output end of the linear motor 4 fixedly connected to the top of the first movable plate 5, the operation of the linear motor 4 driving the first movable plate 5 to rise and fall, a grinding machine 6 fixedly connected to the outer wall of the first movable plate 5, a polishing tool 9 fixedly connected to the output end of the grinding machine 6, the grinding machine 6 for controlling the polishing tool 9 to perform full-speed grinding on the inner wall of the hydraulic cylinder, and a positioning mechanism 7 provided on the top of the base plate 1, the positioning mechanism 7 including a threaded plate 703, the bottom of the threaded plate 703... A sliding connection is made to the top of the base plate 1. A first clamping plate is fixedly connected to the outer wall of the threaded plate 703. The displacement of the two threaded plates 703 can drive the displacement of their respective first clamping plates. The displacement of the two first clamping plates is either moving closer to each other or moving away from each other. When they move closer to each other, they have a clamping effect on the hydraulic cylinder. When they move away from each other, they have a releasing effect on the clamping. A vertical plate 706 is fixedly connected to the top of the processing table 2. A gear 707 is rotatably connected to the outer wall of the vertical plate 706. The vertical plate 706 has a limiting effect on the gear 707, restricting the gear 707 to rotate in place. A second screw 708 is threadedly connected to the inner ring of the gear 707. The rotation of the gear 707 can drive the movement of the second screw 708. A second clamping plate 709 is fixedly connected to one end of the second screw 708. The movement of the second screw 708 drives the movement of the second clamping plate 709, which has a clamping effect.

[0026] Reference Figure 1 - Figure 3A dual-head motor 701 is fixedly connected to the outer wall of the top of the base plate 1. The output end of the dual-head motor 701 is fixedly connected to a first screw 702 via a coupling. The operation of the dual-head motor 701 drives the first screw 702 to rotate. The outer wall of the first screw 702 is threadedly connected to the inner wall of the threaded plate 703. The first screw 702 drives the threaded plate 703 to move. A connecting rod 704 is fixedly connected to the outer wall of the threaded plate 703. The displacement of the threaded plate 703 can drive the connecting rod 704 to move accordingly. A toothed plate 705 is fixedly connected to the outer wall of the connecting rod 704. The displacement of the connecting rod 704 can drive the toothed plate 705 to move. The outer wall of the toothed plate 705 is connected to the gear 705. The outer wall of the 705 is engaged with the gear 707. The gear plate 705 drives the gear 707 to rotate under displacement. The connecting rod 704 has an irregular shape, which serves as a connection. A limit component 710 is provided above the processing table 2. The limit component 710 includes a limit plate and a limit rod. The limit plate is fixedly connected to the other end of the second screw 708. The outer wall of the limit plate is fixedly connected to the limit rod. The outer wall of the limit rod is slidably connected to the inner wall of the vertical plate 706. The limit component 710 limits the second screw 708 to prevent it from rotating during use, thereby controlling the second clamping plate 709 to move linearly. The clamping surfaces of the first clamping plate and the second clamping plate 709 are both flexible. Flexible clamping avoids damage.

[0027] Reference Figure 2 - Figure 4 The polishing tool 9 has an auxiliary mechanism 8 on its top. The auxiliary mechanism 8 includes a second movable plate 802, the bottom of which is slidably connected to the top of the polishing tool 9. A hinge plate 804 is hinged to the top of the second movable plate 802. The displacement of the second movable plate 802 can drive the hinge plate 804 to move. A cleaning plate 805 is hinged to the hinge plate 804. The displacement of the second movable plate 802 controls the two cleaning plates 805 on both sides to move away from each other through the hinge plate 804, thereby allowing the outermost edges of the two cleaning plates 805 to extend out of the polishing tool. The outer wall of the polishing tool 9 allows the cleaning plate 805 to directly contact the inner wall of the hydraulic cylinder, achieving a brushing cleaning effect. The outer wall of the cleaning plate 805 is slidably connected to the outer wall of the polishing tool 9. The top of the second movable plate 802 is fixedly connected to the control plate 803, and the top of the polishing tool 9 is fixedly connected to the electric cylinder 801. The output end of the electric cylinder 801 is fixedly connected to the outer wall of the control plate 803. The operation of the electric cylinder 801 can drive the control plate 803 to move through the extension and retraction of the output end, which in turn can drive the second movable plate 802 to move.

[0028] Working principle: By controlling the start of the dual-head motor 701, the first screw 702 is rotated, which in turn causes the threaded plate 703 to move and the connecting rod 704 to move. The connecting rod 704 then causes the toothed plate 705 to move. The toothed plate 705 meshes with the gear 707, causing the gear 707 to rotate on the outer wall of the vertical plate 706. When the gear 707 rotates, the second screw 708, which is threaded to its inner ring, will move. Because the limiting plate of the limiting component 710 is fixed to the other end of the second screw 708, and the limiting rod is slidably connected to the inner wall of the vertical plate 706, the rotation of the second screw 708 is restricted, so that it can only make linear motion. This causes the second clamping plate 709 to move linearly. The displacement of the two threaded plates 703 will cause their respective first clamping plates to move closer or further apart, cooperating with the second clamping plate 709 to achieve clamping and releasing of the hydraulic cylinder. The flexible clamping surface can avoid damage to the hydraulic cylinder.

[0029] Then, by controlling the linear motor 4 to start, the first movable plate 5 is driven to rise and fall on the outer wall of the fixed plate 3. The grinding machine 6 fixed on the first movable plate 5 moves accordingly. After the polishing tool 9 at the output end of the grinding machine 6 reaches the appropriate position, the grinding machine 6 is started again to drive the polishing tool 9 to perform full-speed grinding and polishing on the inner wall of the hydraulic cylinder placed on the processing table 2. The height of the polishing tool 9 can be adjusted by the linear motor 4 to adapt to the polishing of hydraulic cylinders of different heights.

[0030] When it is necessary to clean up debris and other impurities generated during the polishing process, the electric cylinder 801 is activated. The output end of the electric cylinder 801 extends and retracts, causing the control plate 803 to move. The control plate 803 is fixed on the top of the second movable plate 802, so that the second movable plate 802 slides on the top of the polishing tool 9. When the second movable plate 802 moves, it drives the cleaning plate 805 to move through the hinge plate 804, so that the two cleaning plates 805 move away from each other. The outermost one extends out of the outer wall of the polishing tool 9 and contacts the inner wall of the hydraulic cylinder to brush and clean the inner wall, removing debris and other impurities generated during polishing. After cleaning is completed, the electric cylinder 801 reverses its operation, causing the cleaning plate 805 to return to its initial position.

[0031] 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.
