Technical Field

[0001] This utility model relates to the field of hydraulic cylinder barrel production technology, and more specifically, to a surface treatment device for hydraulic cylinder barrel production. Background Technology

[0002] The cylinder barrel of a hydraulic cylinder is a core component of a hydraulic system, undertaking the important functions of transmitting power and bearing hydraulic pressure. Its production process involves multiple stages, including material selection, precision machining, surface treatment, and quality inspection, which directly affect the life and reliability of the hydraulic cylinder. Surface treatment includes using equipment to grind its inner wall to improve the machining accuracy, surface quality, and overall performance of the cylinder barrel. However, existing technologies have some problems: existing devices can usually only grind hydraulic cylinder barrels of fixed specifications. Different equipment needs to be replaced for cylinder barrels of different specifications. The device has poor compatibility and high changeover costs. Therefore, we propose a surface treatment device for hydraulic cylinder barrel production. Utility Model Content

[0018] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0019] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0020] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0021] like Figure 1-6 As shown, a surface treatment device for the production of hydraulic cylinder barrels includes a base 1. The base 1 is made of stainless steel and its main function is to support the entire device and ensure that the device remains stable during operation.

[0022] Furthermore, a movable platform 2 is movably connected to the base 1. A slide rail is provided on the base 1, and the movable platform 2 is slidably connected in the slide rail. A first hydraulic rod 16 is fixedly connected to the base 1, and the movable platform 2 is fixedly connected to the movable end of the first hydraulic rod 16. The movable platform 2 can be driven to slide in the slide rail of the base 1 by extending or retracting the first hydraulic rod 16.

[0023] Furthermore, a fixed base 3 is fixedly connected to the mobile platform 2, a turntable 4 is rotatably connected to the fixed base 3, a first motor 5 is fixedly connected to one side of the fixed base 3, the turntable 4 is fixedly connected to the output end of the first motor 5, and a clamping component 6 is provided on the turntable 4.

[0024] Specifically, the clamping assembly 6 includes two sets of fixed clamps 61. An adjustment groove is provided on the turntable 4. Both sets of fixed clamps 61 are slidably connected in the adjustment groove. A bidirectional lead screw 62 is rotatably connected in the adjustment groove. The two sets of fixed clamps 61 are respectively threaded to both ends of the bidirectional lead screw 62.

[0025] Furthermore, a throttle 63 is fixedly connected to one end of the bidirectional lead screw 62, and a threaded head 64 is fixedly connected to the other end of the bidirectional lead screw 62. A fastening nut 65 is threaded onto the threaded head 64, and the fastening nut 65 is used to fix the bidirectional lead screw 62.

[0026] Specifically, when fixing the hydraulic cylinder, the fastening nut 65 is loosened, and then the handle 63 is turned to drive the double-acting screw 62 to rotate, so that the two sets of fixing clamps 61 slide along the adjustment groove of the turntable 4 under the thread engagement, thereby changing the distance between the two sets of fixing clamps 61. After clamping the hydraulic cylinder, the fastening nut 65 is tightened to fix the hydraulic cylinder.

[0027] Furthermore, the mobile platform 2 is provided with a sliding groove, and a support platform 7 is slidably connected in the sliding groove. A threaded rod 11 is rotatably connected in the sliding groove of the mobile platform 2. A third motor 12 is fixedly connected in the mobile platform 2. The threaded rod 11 is fixedly connected to the output end of the third motor 12. The support platform 7 is threadedly connected to the threaded rod 11. A second hydraulic rod 13 is fixedly connected to the support platform 7. A support seat 14 is fixedly connected to the movable end of the second hydraulic rod 13. A roller 15 is rotatably connected to the support seat 14.

[0028] Specifically, by starting the third motor 12, the threaded rod 11 is driven to rotate. After the threaded rod 11 rotates, it will slide in the groove of the moving platform 2 under the threaded engagement with the support table 7, so that the support seat 14 on the support table 7 moves to one end of the hydraulic cylinder to support it. At the same time, the roller 15 rotatably connected on the support seat 14 reduces the friction between the hydraulic cylinder and the support seat 14, and avoids the support seat 14 affecting the rotation of the hydraulic cylinder.

[0029] Furthermore, a second motor 9 is fixedly connected to the base 1, and a rotating shaft 10 is fixedly connected to the output end of the second motor 9. A grinding component 8 is provided at one end of the rotating shaft 10.

[0030] Specifically, the grinding assembly 8 includes a grinding head 81, which is fixedly connected to the rotating shaft 10. A guide groove is provided inside the grinding head 81, and a connecting rod 82 is slidably connected inside the guide groove. A grinding disc 83 is fixedly connected to one end of the connecting rod 82.

[0031] Furthermore, a disc 84 is rotatably connected inside the grinding head 81. A guide hole is provided on the disc 84, and a connecting rod 82 is slidably connected in the guide hole. A drive rod 85 is fixedly connected to one side of the disc 84, and a fixing screw 86 is threadedly connected to the grinding head 81. The fixing screw 86 is used to fix the drive rod 85.

[0032] Specifically, by loosening the fixing screw 86, the drive rod 85 is rotated to drive the disc 84 to rotate. After the disc 84 rotates, the connecting rod 82 slides in the guide hole, thereby driving the connecting rod 82 to slide in the guide groove of the grinding head 81, which in turn causes the grinding disc 83 to expand or contract to match the diameter of the hydraulic cylinder. Then the fixing screw 86 is tightened. The grinding assembly 8 enables the device to grind hydraulic cylinders of different diameters.

[0033] The aforementioned surface treatment device for hydraulic cylinder barrel production uses a clamping assembly 6 to fix hydraulic cylinders of different diameters. The device is also equipped with an adjustable support platform 7 and a support base 14, which allows it to support hydraulic cylinders of different lengths, thereby improving the applicability of the device. In addition, the clamping assembly 6 can be rotated by the first motor 5, which in turn drives the cylinder barrel to rotate. This, in conjunction with the rotating grinding assembly 8, accelerates the grinding efficiency.

[0034] This utility model is equipped with a grinding component 8. By loosening the fixing screw 86, the drive rod 85 is rotated to drive the disc 84 to rotate. After the disc 84 rotates, the connecting rod 82 slides in the guide hole, thereby driving the connecting rod 82 to slide in the guide groove of the grinding head 81, which in turn causes the grinding disc 83 to expand or contract to match the diameter of the hydraulic cylinder. Then the fixing screw 86 is tightened. The grinding component 8 enables the device to grind hydraulic cylinders of different diameters.
