Description

Technical Field

[0001] This utility model pertains to hydraulic cylinder body processing devices, specifically a hydraulic cylinder body end face processing device. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or oscillating motion). The hydraulic cylinder body is a part of the hydraulic cylinder. When the hydraulic cylinder body is processed, it needs to be ground. During the grinding process, not only the outer side of the hydraulic cylinder body is ground, but also the inner wall of the hydraulic cylinder body, including the inner wall of the end face of the hydraulic cylinder body.

[0003] The existing grinding method involves using a rotary grinder to grind the inner wall of the hydraulic cylinder from top to bottom. However, this method results in poor grinding quality because debris accumulates inside the hydraulic cylinder. Utility Model Content

[0004] This invention provides a hydraulic cylinder end face machining device to overcome the defects in the prior art.

[0005] This utility model is achieved through the following technical solution:

[0006] A hydraulic cylinder end face processing device includes a base plate, the bottom surface of which is fixed and supported by a column. Clamping devices that prevent the hydraulic cylinder from rotating are provided on both sides of the top surface of the base plate. A through hole is vertically opened on the base plate at the center of the connection line between the two clamping devices. A rotating tube with both ends passing through the through hole is rotatably connected to the through hole through a bearing. The rotating tube is driven by a rotating mechanism to rotate along its axis. A rotating plate is detachably and coaxially fixedly connected to the upper end of the rotating tube. A groove communicating with the rotating tube is opened on the top surface of the rotating plate. The groove is closed by a grinding wheel fixedly set on the rotating plate. The grinding wheel has a group of arc-shaped feed grooves located on corresponding concentric circles. The arc-shaped feed grooves on adjacent groups are connected by a connecting groove. A clamping device that can continuously press down and clamp the hydraulic cylinder is provided above the base plate.

[0007] In use, the hydraulic cylinder body is first placed upside down with the opening facing downwards, so that the grinding wheel contacts the inner wall of the cylinder body end face. The side of the hydraulic cylinder body is clamped using a clamping device, and then the hydraulic cylinder body is pressed down using a pressing device. The rotating mechanism is then started, and the rotation of the rotating mechanism drives the rotation of the rotating tube, which in turn drives the rotation of the rotating plate. The rotation of the rotating plate drives the rotation of the grinding wheel, thereby achieving grinding of the inner wall of the hydraulic cylinder body end face. The grinding debris is fed into the groove of the rotating plate through the corresponding arc-shaped feed groove and connecting groove, and the rotating tube falls down, thus preventing debris from accumulating on the inner wall of the hydraulic cylinder body end face and ensuring a better grinding effect.

[0008] Preferably, the rotating mechanism includes a drive motor fixedly mounted below the base plate, with a drive gear coaxially fixedly connected to the drive motor shaft, and a driven gear meshing with the drive gear sleeved on the rotating tube. The rotation of the drive motor shaft drives the rotation of the drive gear, which in turn drives the rotation of the driven gear, thereby driving the rotation of the rotating tube.

[0009] Preferably, the clamping device includes an inner clamping plate vertically mounted on the base plate, a fixing plate fixedly mounted on the outer side of the inner clamping plate, a screw hole on the fixing plate, a screw threaded into the screw hole, and an outer clamping plate rotatably connected to the inner end of the screw via a bearing. Both the inner and outer clamping plates are arc-shaped plates, and rectangular grooves are provided on the opposite surfaces of the inner and outer clamping plates. A horizontal shaft is fixedly mounted in the rectangular groove, and a wheel rotating along the horizontal shaft is fitted on the horizontal shaft. The wheel has an anti-slip surface. Rotating the screw causes the outer clamping plate to move towards the inner clamping plate, thereby clamping the side wall of the hydraulic cylinder body between the outer and inner clamping plates and the wheel, preventing the hydraulic cylinder body from rotating along its axis. However, when the hydraulic cylinder body is continuously pressed down and moves slightly downward, the wheel can rotate without affecting its downward movement.

[0010] Preferably, the clamping device includes a pressure plate, with support rods vertically connected to both sides of the base plate. The upper ends of the support rods are vertically connected to a top plate, and an electric telescopic rod is vertically connected to the top plate. The movable end of the electric telescopic rod is vertically connected to the pressure plate, and an elastic rubber pad is fixedly installed on the bottom surface of the pressure plate. The continuous downward movement of the electric telescopic rod can drive the pressure plate to move downward, thereby ensuring that a certain pressure is always applied during continuous grinding of the inner wall of the hydraulic cylinder end face.

[0011] Preferably, the top surface of the base plate has an annular groove, the outer diameter of which is the same as the outer diameter of the end of the hydraulic cylinder, and the annular path of the groove is located between the corresponding inner and outer clamping plates. The annular groove increases the downward movement space of the hydraulic cylinder, ensuring better grinding.

[0012] Preferably, the lower end of the rotating tube is vertically and rotatably connected to the horizontal tube via a bearing. The horizontal tube communicates with the rotating tube, with one end closed and the other end connected to the vacuum cleaner's feed inlet. The vacuum cleaner can suck debris into the vacuum cleaner through the rotating tube, thereby preventing debris from splashing when it falls from the rotating tube.

[0013] The beneficial effects of this utility model are as follows: By using this application, the hydraulic cylinder body can be inverted and the grinding wheel can be used for grinding. At the same time, an arc-shaped feed groove is opened on the grinding wheel to ensure that the grinding debris is fed into the groove of the rotating plate through the corresponding arc-shaped feed groove and connecting groove and the rotating tube falls down, thereby avoiding the accumulation of debris on the inner wall of the hydraulic cylinder body end and ensuring a better grinding effect.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] A hydraulic cylinder end face machining device, such as Figures 1-4As shown. It includes a base plate 1, the bottom surface of which is fixed and supported by columns. Clamping devices are provided on both sides of the top surface of the base plate 1 to prevent the hydraulic cylinder from rotating. A through hole is vertically opened on the base plate 1 at the center of the connection line between the two clamping devices. A rotating tube 2 with both ends passing through the through hole is rotatably connected to the through hole through bearings. The rotating tube 2 is driven by a rotating mechanism to rotate along its axis. A rotating plate 3 is detachably fixedly connected to the upper end of the rotating tube 2. A groove communicating with the rotating tube 2 is opened on the top surface of the rotating plate 3. The groove is closed by a grinding wheel 4 fixedly set on the rotating plate 3. The grinding wheel 4 has a group of arc-shaped feed grooves 5 located on corresponding concentric circles. The arc-shaped feed grooves 5 on adjacent groups are connected by connecting grooves. A clamping device is provided above the base plate 1 to continuously press down and clamp the hydraulic cylinder.

[0023] The rotating mechanism includes a drive motor 6 fixedly installed below the base plate 1. The rotating shaft of the drive motor 6 is coaxially fixedly connected to a drive gear 7, and a driven gear 8 that meshes with the drive gear 7 is sleeved on the rotating tube 2.

[0024] The clamping device includes a pressure plate 13. Support rods are vertically connected to both sides of the base plate 1. The upper ends of the support rods are vertically connected to the top plate. An electric telescopic rod 14 is vertically connected to the top plate. The movable end of the electric telescopic rod 14 is vertically connected to the pressure plate 13. An elastic rubber pad is fixedly installed on the bottom surface of the pressure plate 13.

[0025] The clamping device includes an inner clamping plate 10 vertically mounted on a base plate 1. A fixing plate is fixedly mounted on the outer side of the inner clamping plate 10. A screw hole is provided on the fixing plate, and a screw rod 9 is threaded into the screw hole. The inner end of the screw rod 9 is rotatably connected to an outer clamping plate 11 through a bearing. Both the inner clamping plate 10 and the outer clamping plate 11 are arc-shaped plates. A rectangular groove 18 is provided on the opposite surfaces of the inner clamping plate 10 and the outer clamping plate 11. A horizontal shaft is fixedly mounted in the rectangular groove 18. A wheel 12 that rotates along the horizontal shaft is mounted on the horizontal shaft. The wheel 12 is provided with an anti-slip surface.

[0026] In use, the hydraulic cylinder body is first placed upside down with the opening facing downwards, so that the grinding wheel 4 contacts and engages with the inner wall of the cylinder body end face. The side of the hydraulic cylinder body is clamped using a clamping device, and then the hydraulic cylinder body is pressed using a pressing device. The pressing method is as follows: rotating the screw 9 causes the outer clamping plate 11 to move towards the inner clamping plate 10, thereby clamping the side wall of the hydraulic cylinder body with the wheels 12 on the outer clamping plate 11 and the inner clamping plate 10, preventing the hydraulic cylinder body from rotating along its axis. However, when the hydraulic cylinder body is continuously pressed down and moves slightly downwards, the wheels 12 can rotate without affecting its downward movement.

[0027] Then, the rotating mechanism is activated: the drive motor 6 is started, and the rotation of the drive motor 6 shaft drives the rotation of the drive gear 7, which in turn drives the rotation of the driven gear 8, thereby driving the rotation of the rotating tube 2. The rotation of the rotating tube 2 drives the rotation of the rotating plate 3, and the rotation of the rotating plate 3 drives the rotation of the grinding wheel 4, thus achieving the grinding of the inner wall of the hydraulic cylinder end face. The grinding debris is fed into the groove of the rotating plate 3 through the corresponding arc-shaped feed groove 5 and connecting groove, and falls into the rotating tube 2, thereby preventing debris from accumulating on the inner wall of the hydraulic cylinder end face and ensuring a better grinding effect.

[0028] During grinding, the continuous downward movement of the electric telescopic rod 14 can drive the pressure plate 13 to move downward, thereby ensuring that a certain pressure is always applied when grinding the inner wall of the hydraulic cylinder end face.

[0029] The bottom plate 1 has an annular groove 15 on its top surface. The outer diameter of the annular groove 15 is the same as the outer diameter of the end of the hydraulic cylinder, and the annular path of the annular groove 15 is located between the corresponding inner clamping plate 10 and outer clamping plate 11. The annular groove 15 can increase the downward movement space of the hydraulic cylinder, ensuring better grinding.

[0030] The lower end of the rotating tube 2 is vertically and rotatably connected to the horizontal tube 16 via a bearing. The horizontal tube is fixedly mounted on the column, and the drive motor 6 is fixedly mounted on the horizontal tube 16. The horizontal tube 16 communicates with the rotating tube 2, with one end closed and the other end connected to the feed inlet of the vacuum cleaner 17. The vacuum cleaner 17 can suck debris into the vacuum cleaner 17 through the rotating tube 2, thereby preventing debris from splashing when it falls from the rotating tube 2.

[0031] The use of this application allows for grinding by inverting the hydraulic cylinder body and using a grinding wheel 4. At the same time, an arc-shaped feed groove 5 is provided on the grinding wheel 4 to ensure that the grinding debris passes through the corresponding arc-shaped feed groove 5 and connecting groove into the groove of the rotating plate 3 and the rotating tube 2 falls down, thereby avoiding the accumulation of debris on the inner wall of the hydraulic cylinder body end and ensuring a better grinding effect.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
