Description

Technical Field

[0001] This utility model relates to the technical field of slant bed clamps, specifically to a 45° slant bed hydraulic clamp. Background Technology

[0002] As the carrier of machined parts, CNC machine tools have strict requirements for the precision of the machine tool itself (such as flatness, coaxiality, perpendicularity, etc.). Only when the machine tool has high precision can the machined products be qualified, and only then can the precision of the assembled machine tool be qualified. Therefore, to solve the precision problem of CNC machine tools, the precision of the machine tool parts must meet specific requirements. To make the machine tool parts meet specific requirements, it is necessary to design hydraulic fixtures (tooling) that can meet the processing conditions.

[0003] For example, the LTR-8 CNC lathe has a 45° bed. The workpiece itself is inclined at 45°, which has certain special characteristics. The machining accuracy (flatness, perpendicularity, parallelism) of the linear guide surface, bearing surface, and spindle box mounting surface is strictly required. Without tooling, the machining is difficult. Ordinary welding tooling is prone to errors of varying degrees during the welding process. When using tooling, a large number of tooling accessories need to be prepared, such as drawbars, pressure plates, and pressure plate supports, which increases the preparation time and the workload of the operator. Therefore, there is an urgent need to design a hydraulic fixture that can quickly meet the machining conditions. Utility Model Content

[0004] To address the aforementioned problem—namely, designing a fixture capable of quickly clamping a slant bed—this invention proposes a 45° slant bed hydraulic fixture. The fixture includes a mounting base plate, on which a base is mounted. Several inclined slides are mounted on the base, with the slides equidistantly spaced. An adjustable support is provided between any two slides, and this adjustable support is extendable. A V-shaped plate is also mounted on the mounting base plate, with its inclined surface perpendicular to the slides and forming a V-shape with the slides. A hydraulic locking element is mounted on the inclined surface of the V-shaped plate for locking the workpiece on the bed.

[0005] A further feature of this invention is that two V-shaped plates are provided, and the two V-shaped plates are equidistant from each other.

[0006] A further feature of this invention is that two hydraulic locking components are provided on the inclined surface of each V-shaped plate, and the two hydraulic locking components are equidistant from each other.

[0007] A further feature of this invention is that a device plate is also installed on the inclined surface of the V-shaped plate corresponding to each of the hydraulic locking components, for supporting the bed workpiece.

[0008] A further feature of this invention is that the hydraulic locking component includes a cylinder body, a retractable piston rod is sleeved inside the cylinder body, one end of the piston rod extends out of the cylinder body, a pressure block is rotatably connected to one end of the piston rod outside the cylinder body, a connecting rod is rotatably connected to the middle of the pressure block, and the end of the connecting rod away from the pressure block is rotatably connected to the cylinder body.

[0009] A further feature of this invention is that each of the slide tracks is equipped with a plurality of rollers, the rollers are rotatably connected to the slide tracks, and the axis of the rollers is perpendicular to the slide tracks.

[0010] A further feature of this invention is that a limiting block is installed at one end of the base, the limiting block being used to limit the axial movement of the workpiece on the bed, and an adjustable side top is also installed on the mounting base plate, the adjustable side top being located on the side of the base away from the limiting block, and the adjustable side top being located at the middle position between the V-shaped plate and the slide rail.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. Through the cooperation of V-blocks and hydraulic locking components, the machine bed can quickly support, clamp, and release workpieces while ensuring accurate positioning. Furthermore, the clamping is reliable, convenient, quick, and simple to operate, making it suitable for mass production.

[0013] 2. The structure of this utility model is more compatible with the slant bed, and can withstand greater cutting stress during rough machining. The clamping force is adjustable and the force is evenly distributed, avoiding the problem of workpiece deformation caused by different forces due to manual clamping. Attached Figure Description

[0019] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0020] This utility model proposes a 45° slant bed hydraulic clamp, including a mounting base plate 1, a base 2 connected to the mounting base plate 1 by bolts, and three slide rails 3 fixedly connected to the base 2 by bolts. The slide rails 3 are inclined, forming a 45° angle with the mounting base plate 1, and the three slide rails 3 are equidistant. An adjustable support 4 is also provided between any two slide rails 3. The adjustable support 4 is a hydraulic telescopic device, and is connected to the base 2 by a fixing block. The fixing block is pulled down and connected to the base 2 by screws. The surface of the fixing block on which the adjustable support 4 is mounted is set as an inclined plane with an angle of 45°.

[0021] A V-shaped plate 5 is also bolted to the mounting base plate 1. The cross-section of the V-shaped plate 5 is an isosceles right triangle, with one right-angled face connected to the mounting base plate 1 by bolts. The inclined surface of the V-shaped plate 5 faces the slide rail 3, and the inclined surface of the V-shaped plate 5 forms a 45° angle with the mounting base plate 1. That is, the inclined surface of the V-shaped plate 5 is perpendicular to the slide rail, and the two are arranged in a V-shape.

[0022] A hydraulic locking component 6 is installed on the inclined surface of the V-shaped plate 5. The hydraulic locking component 6 is used to lock the workpiece 9 of the bed.

[0023] Two V-shaped plates 5 are provided, and the two V-shaped plates 5 are equidistant from each other. Two hydraulic locking components 6 are fixedly connected to each V-shaped plate 5, and the two hydraulic locking components 6 are also equidistant from each other. A device plate 51 is also connected to the inclined surface of the V-shaped plate 5 through countersunk holes and screws. The device plate 51 is set corresponding to the hydraulic locking components 6, that is, there is a device plate 51 below each hydraulic locking component 6. During operation, the machining surface of the workpiece 9 on the bed will be directly supported on the device plate 51 and will not directly contact the inclined surface of the V-shaped plate 5.

[0024] The hydraulic locking component 6 includes a cylinder body 61, within which a piston rod 62 is coaxially sleeved. The piston rod 62 can extend and retract within the cylinder body 61; that is, the extension and retraction of the piston rod 62 is controlled by the hydraulic oil within the cylinder body 61 through a hydraulic system. The piston rod 62 is positioned perpendicular to the inclined surface of the V-shaped plate 5. One end of the piston rod 62 extends out of the cylinder body 61 and is rotatably connected to a pressure block 63. One end of the pressure block 63 is rotatably connected to the piston rod 62, and a connecting rod 64 is rotatably connected to the middle of the pressure block 63. The end of the connecting rod 64 facing away from the pressure block 63 is rotatably connected to the cylinder body 61. Thus, the angle of the pressure block 63 can be adjusted through the combined action of the piston rod 62 and the connecting rod 64. (Reference) Figure 1 This indicates that the piston rod 62 is retracted and the pressure block 63 is relaxed. (Refer to...) Figure 3 Then, the piston rod 62 extends and the pressure block 63 presses down to clamp the workpiece 9 on the bed.

[0025] It should be noted that the hydraulic locking component 6 needs to be set to correspond to the weight reduction groove on the workpiece 9 of the bed. When clamping, the hydraulic locking component 6 needs to be clamped into the weight reduction groove.

[0026] Each slide rail 3 is equipped with five rollers 31. The five rollers 31 are arranged at equal intervals along the length of the slide rail and extend out of the slide rail 3. The rollers 31 are rotatably connected to the slide rail 3. The axis of the rollers 31 is perpendicular to the slide rail 3. When the bed workpiece 9 is installed, one side of the bed workpiece 9 will abut against the rollers 31, which makes it easier for the bed workpiece 9 to be installed in the fixture.

[0027] A limiting block 21 is also fixedly connected to the upper surface of the base 2. The limiting block 21 is used to restrict the axial movement of the bed workpiece 9. That is, during operation, one end of the bed workpiece 9 abuts against the limiting block 21. An adjustable side top 7 is also bolted to the mounting base plate 1. The adjustable side top 7 is located on the side of the base 2 away from the limiting block 21, and the position of the adjustable side top 7 is at the middle position between the V-shaped plate 5 and the slide groove.

[0028] The adjustable side top 7 includes an adjustment seat 71, which is bolted to the base 2. A top column 72 is threaded onto the adjustment seat 71. The two ends of the top column 72 are respectively located on both sides of the adjustment seat 71. The end of the top column 72 closer to the base 2 is used to abut against the workpiece 9 of the bed. A handwheel 73 is fixedly connected to the end of the top column 72 away from the base 2. By rotating the handwheel 73, the top column 72 can be moved along its axial direction, thereby tightening and loosening the workpiece 9 of the bed. In conjunction with the limiting block 21, it can achieve axial positioning of the workpiece 9 of the bed.

[0029] It should be noted that the reference Figure 1An auxiliary support block 8 is also installed on the mounting base plate 1. The auxiliary support block 8 is located below the slide groove. The end of the auxiliary support block 8 near the V-shaped plate 5 is set as a 45° inclined surface. Its inclined surface is on the same horizontal plane as the slide 3. During operation, the auxiliary support block 8 can provide auxiliary support for the workpiece 9 of the bed, making it more stable.

[0030] In summary, this invention, through the cooperation of the V-block and the hydraulic locking component 6, enables rapid support, clamping, and release of the workpiece 9 on the machine bed, ensuring accurate positioning. Furthermore, it offers reliable clamping, convenient and quick use, and simple operation, making it suitable for mass production. The structure of this invention is better suited to slant bed machines, allowing it to withstand greater cutting stress during rough machining. The clamping force is adjustable and evenly distributed, avoiding the workpiece deformation problems caused by uneven force distribution in manual clamping systems.
