Description

Technical Field

[0001] This utility model relates to the field of pressure head technology, and in particular to a spherical universal pressure head. Background Technology

[0002] In the machining process, power components, such as hydraulic presses or cylinders, are often used to fix mechanical parts and then perform targeted processing. The output end of a hydraulic press or cylinder is usually connected to a pressure head, which contacts the workpiece to achieve the fixing effect.

[0003] The movement trajectory of hydraulic presses or cylinders is always a straight line. Therefore, when processing parts, the movement trajectory of the press head is also a straight line. However, some special parts, such as sheet metal on automobiles, have curved surfaces. In this case, a press head that can automatically adjust its angle is needed to achieve a complete fit between the press head and the surface of the part.

[0004] However, the existing pressure heads that can automatically adjust the angle according to the surface of the part have overly complex structures, short lifespans, and cannot work stably for a long time. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that the existing technologies have overly complex structures, and to propose a spherical universal pressure head.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A spherical universal pressure head includes a spherical seat and a pressure block, wherein the bottom of the spherical seat can fit against the top of the pressure block; a connecting ring is fixedly connected to the top of the pressure block, and the spherical seat is snapped into the connecting ring; an adjustment gap is provided between the spherical seat and the connecting ring.

[0008] Preferably, a connecting plate is fixedly connected to the top of the spherical seat.

[0009] Preferably, it further includes a connecting rod; both the spherical seat and the pressure block are provided with through holes, the connecting rod passes through the through holes, and there is a gap between the connecting rod and the through holes; the bottom of the connecting rod is threadedly connected to the pressure block; the connecting rod is provided with an adjusting plate, and the bottom of the adjusting plate is provided with a spring.

[0010] Preferably, the adjusting plate is slidably connected to the connecting rod; a nut is threaded onto the top of the connecting rod, and the nut is in contact with the upper surface of the adjusting plate.

[0011] Preferably, the bottom of the spherical seat is provided with an oil groove, and the pressure block is provided with an oil filling hole; the oil filling hole and the oil groove are interconnected.

[0012] Preferably, a protective cover is connected between the spherical seat and the pressure block; the connecting ring is located inside the protective cover.

[0013] Preferably, the connecting plate is provided with a connecting hole.

[0014] Compared with the prior art, this utility model provides a spherical universal pressure head, which has the following beneficial effects:

[0015] 1. This spherical universal pressure head features a design where the spherical seat and the pressure block fit together, and is limited by a connecting ring. The structure is simple, and when adjusting the angle in any direction, only the pressure block needs to rotate relative to the spherical seat. This greatly improves the stability of the work, extends the service life, and ensures long-term operation.

[0016] 2. When the ball-shaped universal pressure head is not in contact with the parts, the spring force can make the ball seat and the pressure block fit together, preventing the pressure block from shaking due to the existence of adjustment gap. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example:

[0026] like Figures 1-5 A spherical universal pressure head includes a spherical seat 2 and a pressure block 201, wherein the bottom of the spherical seat 2 can fit against the top of the pressure block 201, such as... Figure 2 , Figure 4 , Figure 5 The bottom of the spherical seat 2 is spherical, and the top of the pressure block 201 is also a matching spherical concave design.

[0027] A connecting ring 202 is fixedly connected to the top of the pressure block 201. The connecting ring 202 is fixedly connected to the pressure block 201 by screws, and the ball seat 2 is snapped into the connecting ring 202; Figure 2 and Figure 3 An adjustment gap 4 is provided between the spherical seat 2 and the connecting ring 202.

[0028] The ball seat 2 is snapped into the connecting ring 202, and can rotate freely and have its angle adjusted freely by adjusting the gap 4.

[0029] During operation, the top of the ball seat 2 is connected to a power component, such as a cylinder or hydraulic cylinder, which drives the ball seat 2 to move toward the part that needs to be fixed.

[0030] When the pressure block 201 contacts the surface of the part, the spherical design at the bottom of the spherical seat 2 allows the pressure block 201 to rotate relative to the spherical seat 2 according to the angle of the part surface, automatically adjusting the angle to adapt to different shaped parts surfaces, so that the pressure block 201 can fit perfectly against the part surface and achieve the purpose of fixing.

[0031] When the pressure block 201 is adjusted at an angle, it moves the connecting ring 202 together. By adjusting the gap 4, interference between the connecting ring 202 and the ball seat 2 is avoided.

[0032] Adjust the gap 4 width to 1-3cm so that the pressure block 201 can rotate between 0-20° at any angle.

[0033] Considering stability, such as automotive sheet metal, the surface of the parts will not undergo significant tilting changes. The pressure block 201 can rotate to any angle, up to 20°, which is sufficient for the application scenarios.

[0034] With the design of the ball seat 2 and the pressure block 201 fitting together, and the limiting by the connecting ring 202, the structure is simple. When adjusting the angle in any direction, only the pressure block 201 needs to rotate relative to the ball seat 2, which greatly improves the stability of the work, extends the service life, and ensures long-term operation.

[0035] A connecting plate 1 is fixedly connected to the top of the ball seat 2. The connecting plate 1 is fixedly connected to the ball seat 2 by screws. The connecting plate 1 is provided with a connecting hole 101.

[0036] The spherical universal pressure head connects the connecting plate 1 to the power component through the connecting hole 101.

[0037] like Figure 1 , Figure 2 , Figure 4 The spherical universal pressure head disclosed in this embodiment also includes a connecting rod 3; both the spherical seat 2 and the pressure block 201 are provided with through holes, and both the connecting plate 1 and the spherical seat 2 are rotating parts, with the through holes located at the axis of rotation of the connecting plate 1 and the spherical seat 2.

[0038] The connecting rod 3 passes through the through hole, and there is a gap between the connecting rod 3 and the through hole; the bottom of the connecting rod 3 is threadedly connected to the pressure block 201; the connecting rod 3 is provided with an adjusting plate 301, and the bottom of the adjusting plate 301 is provided with a spring 302. The top of the spring 302 abuts against the adjusting plate 301, and the top of the spring 302 can abut against the connecting plate 1, or it can pass through the connecting plate 1 and abut against the ball seat 2.

[0039] like Figure 2 The connecting rod 3 has an external thread on its side wall, and the pressure block 201 also has a threaded hole at the center of its top spherical concave shape. The bottom of the connecting rod 3 is threadedly connected to the threaded hole.

[0040] During periods when there is no contact with the parts, the elastic force of the spring 302 can keep the ball seat 2 and the pressure block 201 in contact with each other, preventing the pressure block 201 from shaking due to the existence of the adjustment gap 4.

[0041] The adjusting plate 301 is slidably connected to the connecting rod 3; a nut 303 is threadedly connected to the top of the connecting rod 3, and the nut 303 is in contact with the upper surface of the adjusting plate 301.

[0042] By rotating the nut 303 and adjusting the position of the plate 301, the reverse force applied by the spring 302 can be flexibly adjusted; when the spring 302 experiences metal fatigue and its elasticity decreases after long-term operation, it is also convenient to replace the spring 302.

[0043] like Figure 2 and Figure 5The bottom of the spherical seat 2 is provided with an oil groove 5. The oil groove 5 is distributed along the warp and weft directions at the bottom of the spherical seat 2 and is interconnected. The pressure block 201 is provided with an oil filling hole 501. The oil filling hole 501 is interconnected with the oil groove 5.

[0044] The oil tank 5 is in contact with the top of the pressure block 201.

[0045] Lubricating oil is added to the oil trough 501 through the oil filling hole to prevent excessive frictional resistance between the pressure block 201 and the ball seat 2 when the pressure block 201 rotates.

[0046] The side wall of the pressure block 201 is also fixed with an oil seal cap by screws. After adding lubricating oil, the oil filling hole 501 is blocked by the oil seal cap.

[0047] A protective cover 6 is connected between the ball seat 2 and the pressure block 201; the connecting ring 202 is located inside the protective cover 6; the protective cover 6 is made of rubber, has elasticity, and has a corrugated tube shape.

[0048] The protective cover 6 effectively prevents dust from entering the adjustment gap 4, thus improving stability.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
