Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder manufacturing technology, specifically to a cutting device for manufacturing and processing hydraulic cylinder end cap accessories. Background Technology

[0002] Hydraulic cylinders are a commonly used component in the machinery manufacturing industry. A hydraulic cylinder is basically composed of a cylinder barrel and end caps, a piston and piston rod, a sealing device, a buffer device, and an exhaust device. Among them, the end caps play the roles of support, sealing, power transmission, and movement, and are an essential and important part of the hydraulic cylinder. As a key sealing and connecting component of the hydraulic cylinder, the machining accuracy of the hydraulic cylinder end caps directly affects the overall performance of the hydraulic cylinder. In the production and processing of hydraulic cylinder end caps, cutting is the core process to ensure its dimensional accuracy and surface quality, and it requires a special cutting device to complete.

[0003] In the existing hydraulic cylinder end cap cutting device, most of them use chucks or positioning seats of fixed specifications. When machining hydraulic cylinder end caps of different diameter specifications, it is necessary to change the fixture, which is cumbersome and time-consuming, reducing production efficiency. In addition, during the cutting process, one cutting edge is often used for cutting, and the other side is not supported or the cutting edge is not matched, which can easily affect the cutting accuracy. Therefore, it is necessary to make improvements. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a cutting device for the production and processing of hydraulic cylinder end cap accessories to solve the above problems.

[0005] The purpose of this utility model is achieved as follows: A cutting device for manufacturing and processing hydraulic cylinder end cap accessories includes a worktable, a support plate fixedly connected to the upper end of the worktable, a rotating disk rotatably connected to the side of the support plate, a positioning shaft for fitting an end cap blank on the side of the rotating disk, a slot on the upper surface of the worktable, a bearing seat in the slot, a bidirectional lead screw rotatably mounted on the bearing seat, a movable block at the thread of the bidirectional lead screw, the side wall of the movable block fitting against the side wall of the slot, and a cutting component at the upper end of the movable block.

[0006] Preferably, the cutting assembly includes a mounting rod disposed on the upper end of the movable block, the mounting rod having a mounting plate on its side, and the mounting plate having a cutting edge.

[0007] Preferably, the workbench is provided with a baffle, which is located above the slot.

[0008] Preferably, the upper end of the slot is provided with an installation groove, and the side wall of the baffle is placed in the installation groove.

[0009] Preferably, the baffle has inclined plates integrally formed at both ends.

[0010] Preferably, a support beam is inclinedly provided between the side of the support plate and the upper surface of the workbench.

[0011] This utility model has the following beneficial effects: 1. This cutting device for manufacturing hydraulic cylinder end cap parts uses a cylindrical end cap blank to be mounted on a positioning shaft. The blank is coaxially fixed by a rotating disc. Rotating the bidirectional lead screw causes relative displacement of the two movable blocks on either side due to its reverse thread design and contact with the sidewall. The cutting components move synchronously towards or away from the slotted sidewall. After the cutting components are adjusted to the appropriate working position, the rotating disc drives the end cap blank to rotate at a uniform speed, bringing the cutting components into contact with the blank surface and completing the cutting process. This device eliminates the need to change fixtures. By adjusting the spacing of the movable blocks using the bidirectional lead screw, it can accommodate end cap blanks of different diameters, solving the problem of cumbersome and time-consuming fixture changes in existing technologies, improving production efficiency. Furthermore, it enables symmetrical cutting or dual-sided collaborative processing, avoiding uneven force and displacement of the blank caused by unilateral cutting, and overcoming the low precision of unilateral cutting in existing technologies.

[0012] 2. A baffle is provided on the workbench, located above the slot. The baffle prevents debris from splashing directly to the connection between the bearing seat and the double-acting screw inside the slot through physical shielding, thus extending the service life. An installation groove is provided at the upper end of the slot, and the side wall of the baffle is placed in the installation groove. The installation groove restricts the lateral and longitudinal displacement of the baffle, preventing the baffle from shifting due to cutting vibration and ensuring the shielding effect.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0016] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0017] Example 1: A cutting device for manufacturing hydraulic cylinder end cap parts includes a worktable 1, a support plate 2 fixedly connected to the upper end of the worktable 1, a rotating disk 3 rotatably connected to the side of the support plate 2, the rotating disk 3 can be driven to rotate by an external power source such as a motor, a positioning shaft 4 for fitting end cap blank 5 on the side of the rotating disk 3, a slot 6 on the upper surface of the worktable 1, a bearing seat 7 in the slot 6, a double-acting lead screw 8 rotatably mounted on the bearing seat 7, a movable block 9 at the thread of the double-acting lead screw 8, the side wall of the movable block 9 fitting against the side wall of the slot 6, and a cutting component 10 at the upper end of the movable block 9.

[0018] When using this device, the cylindrical end cap blank 5 is fitted onto the positioning shaft 4. The blank is coaxially fixed by the positioning action of the rotating disk 3. The bidirectional lead screw 8 is rotated. The bidirectional lead screw 8 can be driven manually by a handwheel or by an external stepper motor. Mature existing technologies can be used. Due to the positive and negative thread design of the bidirectional lead screw 8 and its contact with the side wall, the two movable blocks 9 on both sides will undergo relative displacement, that is, they will move closer or further away from each other synchronously along the side wall of the slot 6. After the cutting component 10 is adjusted to the appropriate working position with the movable block 9, the end cap blank 5 is driven to rotate at a uniform speed by the rotating disk 3, so that the cutting component 10 contacts the surface of the blank and completes the cutting process. This device eliminates the need to change fixtures. By adjusting the spacing of the movable blocks 9 via the bidirectional lead screw 8, it can adapt to end cap blanks 5 of different diameters. This solves the problem of cumbersome and time-consuming fixture changes in existing technologies, improves production efficiency, and enables symmetrical cutting or double-sided collaborative processing. It avoids uneven force and displacement of the blank caused by unilateral cutting, thus solving the defect of low precision in unilateral cutting in existing technologies.

[0019] In this embodiment, the cutting assembly 10 includes a mounting rod 101 disposed on the upper end of the movable block 9. A mounting plate 102 is provided on the side of the mounting rod 101. The mounting plate 102 is provided with a cutting edge 103. The cutting edge 103 is made of YT15 cemented carbide and is fixed to the cutting surface of the mounting plate 102 by two M6×12 bolts. The mounting rod 101 is vertically fixed to the upper end of the movable block 9. The mounting plate 102 is connected to the mounting rod 101 by bolts or welding. The cutting edge 103 is assembled on the machining surface of the mounting plate 102, and material removal is achieved by the sharp edge of the cutting edge 103.

[0020] In this embodiment, a baffle 11 is provided on the workbench 1. The baffle 11 is located above the slot 6. The baffle 11 prevents debris from splashing directly to the connection between the bearing seat 7 and the double-acting screw 8 inside the slot 6 by physical shielding, thus extending the service life.

[0021] In this embodiment, the upper end of the slot 6 is provided with a mounting groove 12, and the side wall of the baffle 11 is placed in the mounting groove 12. The mounting groove 12 restricts the lateral and longitudinal displacement of the baffle 11, avoids the baffle 11 from shifting due to cutting vibration, and ensures the shielding effect.

[0022] In this embodiment, inclined plates 13 are integrally formed at both ends of the baffle 11. The inclined plates 13 widen the shielding range of the baffle 11 and further block debris from splashing in both directions.

[0023] In this embodiment, a support beam 14 is inclinedly arranged between the side of the support plate 2 and the upper surface of the workbench 1. When the rotating disk 3 drives the end cover blank 5 to rotate at high speed, radial torque and vibration will be generated. The support beam 14 offsets part of the torque and vibration through oblique tension and support force, thereby enhancing the deformation resistance of the support plate 2.

[0024] The working principle of this utility model is as follows: This cutting device for the production and processing of hydraulic cylinder end cap accessories involves placing a cylindrical end cap blank 5 on the positioning shaft 4. The blank is coaxially fixed by the positioning action of the rotating disk 3. Rotating the bidirectional lead screw 8 causes relative displacement of the two movable blocks 9 on both sides due to the positive and negative thread design of the lead screw 8 and its contact with the side wall. That is, they move synchronously closer or further away along the side wall of the slot 6. After the cutting component 10 follows the movable blocks 9 to the appropriate working position, the rotating disk 3 drives the end cap blank 5 to rotate at a uniform speed, causing the cutting component 10 to contact the surface of the blank and complete the cutting process. This device eliminates the need to change fixtures. By adjusting the distance between the movable blocks 9 using the bidirectional lead screw 8, it can accommodate end cap blanks 5 of different diameters, solving the problem of cumbersome and time-consuming fixture changes in existing technologies, improving production efficiency, and enabling symmetrical cutting or double-sided collaborative processing. This avoids uneven force and displacement of the blank caused by unilateral cutting, and solves the defect of low precision in unilateral cutting in existing technologies.

[0025] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be divided into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model. The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
