INDUSTRIAL APPLICABILITY The present invention is capable of smoothly feeding and precisely feeding on a friction surface by supplying grease, which is a lubricant, to a slide feeder of an adjusting part for fine precision control in industrial machinery and photographing equipment. And a control unit lubricant hydraulic supply device for a photographic device.

Conventional rotation control devices for adjusting the opening and closing of various valves, such as fastening, repositioning, etc. in industrial machinery, fastening / release for fastening the ball head in the camera, and various valves, Usually connected directly to the rotating handle and the shaft fastened to the handle, or by using a bush or a bearing on the shaft fastened to the adjusting part, or by horizontally conveying the feeding screw fastened to the shaft of the adjusting part, By moving the interlocking bar integrally, the conveying member coupled to the interlocking bar moves to a predetermined position.

In this transfer configuration, the nut of the handle part and the feed screw are screwed together, and the interlocking rod is inserted into the body part, so that friction is generated together with the slides at their joints, and rotation is suppressed during transfer according to the processing irregularities formed on the close contact surface. Due to the jamming and the like can not achieve a precise transfer has been a lot of problems in the ultra-precision equipment.

In addition, there is a closed end that the control knob of the control unit is not in the correct position when used, and the position of the control unit is changed even in the minute vibration.

Accordingly, the friction surface is finely machined to reduce the frictional force, and grease lubricant is supplied to the friction portion.

The micro-processing of the friction surface has a problem that it is extremely difficult to meet the desired stability due to wear and wear due to friction between the metal material and wear due to its limitation.

Accordingly, grease (lubrication) is supplied to help lubrication, and these greases are semi-solid or solid lubricants at room temperature so that they can be smoothly transferred from the lubrication parts of various machines, especially screwing and bearings. The additives contribute to the longevity of the machine with anti-oxidation, anti-rust, anti-corrosion and anti-wear agents.

However, the grease supplied is filled around the coupling part while the feed rod penetrated through the screw connection part and the guide hole is slide-bonded, so that grease flows into the contact part of the screw thread and the screw and lubricant can be supplied to the friction surface. If the initial application state is lost, no lubrication can be performed.

That is, the threaded rod, the feed rod fitted to the guide hole, etc. are precisely processed for the reasons of their bondability and stability, so that they do not form a space for the grease to flow into the joining portion. It is not possible to enter the friction surface.

In order to improve this problem, there is a configuration in which a lubricant injection hole is injected into the coupling part, that is, the nut part and the screw are in close contact with each other in the mechanical configuration.

The above configuration is to provide a very fine supply to the coupling portion in which the lubricant supplied to the injection hole is in close contact with the slide effect is very small, and some of them are pushed out to the outside due to the close contact causes a problem that the effect does not last long.

Therefore, in machine tools and the like, an oil supply flow path is formed in the metal, and the oil is supplied to the supply flow path and the injection hole drilled outward to improve the degree of oil filled in the space formed on the metal on the surface of the rotating shaft.

However, the configuration in which the supply flow path is formed cannot be formed in the entire friction part and is formed at a predetermined position, so that the friction surface that the oil supply cannot reach has high wear rate, cannot achieve smooth transfer and rotation, and noise due to friction increases. Due to the relatively different wear rate between the frictional wear part and the oil-supplied part, it is a cause of failure of the device.

According to such uneven wear, a lot of problems occur, such as cause of shortening the life of the equipment when excessive force is applied, and leads to accidents due to cracks are broken.

In addition, as frictional wear increases, screwing becomes loose and slides are not generated uniformly, so precise feeding cannot be performed, which reduces reliability in precision devices.

In particular, in the close structure composed of male and female, even if the lubricant cannot be supplied to the close coupling surface has not been provided with a separate configuration for forced supply.

Therefore, the lubricant supplied around the moving member is not supplied to the combined friction surface and is merely accumulated in the surroundings, so that the above problems cannot be improved.

The present invention has been made in view of the above-described situation, and particularly, when the female and female members are coupled and the female and male members are transported, the lubricant filled with the transfer force is forcibly forced into the combined friction surface of the female and female members. It is an object to supply sufficient lubricant to the friction surface by forcibly supplying a lubricant.

The present invention is simple in construction and easy to manufacture, and features a trouble-free feature and the forced lubrication of the filled lubricant so that the lubricant is supplied to the friction surface of the micro-gap, so that the slide of the transfer member in the friction surface is easy to fine control and precise The aim is to prevent the failure by significantly adjusting the wear rate and to reduce the wear rate, and to add a hydraulic pressure to the components to achieve a stable use effect.

The present invention for achieving the above object is a female member and a male member to achieve a stable and fine movement of the conveying member in the adjustment device for achieving tightening and disengagement and change of position, opening and closing, etc. Lubricant is supplied to the friction surface of the liver to force the lubricant to achieve a smooth slide.

An embodiment of the present invention will be described as an example the ball head adjusting device of the camera.

That is, the ball head adjusting device of the embodiment is to adjust the direction angle with the object by fixing or rotating the camera to a stable fixed and precise angle on a tripod.

In the first embodiment of the ball head of the camera, when rotating the handle which is the female member, the male member screw, which is fastened to the nut in the handle, is horizontally moved and screwed to the male member according to the rotation of the female member. As the conveying rod, which is the conveying member, moves linearly, the pressing member or the opening / closing member fastened to the conveying rod is moved to perform a predetermined press / release or open / close action.

At this time, the nut screw portion of the female member and a screw which is a male member fastened thereto are screwed together, and the transfer rod, which is a transfer member, is slide-transmitted in close contact with the guide hole of the body.

The screw coupling rotation and the coupling portion in the slide transfer is due to the friction between the processing irregularities and the metal material is difficult to precisely rotate or the transfer is hampered by shortage of durability and wear play occurs because the transfer is hindered.

The present invention constitutes a space stepping chamber in which the male member is movable to the female member, thereby supplying a sufficient amount of lubricant to the stepping chamber, and the screw of the male member forms a lubricant moving channel through which the supplied lubricant can move back and forth.

With this configuration, when the screw of the male member fastened to the nut is moved back and forth by rotating the female member, the lubricant filled in the pressure chamber in the female member compresses the lubricant in the pressure chamber in the moving direction by the movement of the male member. Lubricant is forcedly supplied to the micro-gap between the screw joint and the guide hole, thereby forcibly supplying the lubricant to the friction surface of the micro-gap.

At this time, when pressure is added above a predetermined pressure, a plurality of flow paths in which the lubricant is movable in the male member is formed in a predetermined size to achieve lubricant supply to the rear portion of the male member in order to prevent a phenomenon in which the male member is difficult to move or reversely move. The lubricant is transferred to the other side through the flow path at a predetermined pressure or more to maintain a constant pressure.

In the unwinding action, the screw to which the transferred lubricant is returned is moved to reduce the pressure in the pressure chamber to compress the lubricant in the pressure chamber so that the forced supply of the lubricant into the gap is possible.

When the lubricant 41 is injected into the pressure chamber 40 of the present invention and the female member 20 is fastened to the nut part 11 by rotating the female member 10 in the injected state, the pressure chamber of the forward portion ( 40) The area is reduced and the lubricant 41 filled by the pressure generated at this time is forcibly supplied to the screw engagement gap, which is a fine gap, and the slide surface gap of the guide hole 51, thereby sufficiently supplying the lubricant to the friction surface to reduce the wear rate. At the same time, a stable conveyance can be achieved, and at a predetermined pressure or more, the lubricant 41 moves to the moving flow path 23 formed through the screw 21 of the male member 20 to move to the step-down chamber 40 at the reverse position of the other side. To keep the pressure moderate.

In addition, when the arm member 10 is rotated in the unwinding direction, the screw is moved in the reverse direction, thereby compressing the lubricant 41 in the pressure chamber 40 again to forcibly supply the lubricant 41 to each gap.

Embodiment 2 of the present invention is an operation explanatory diagram for advancing the male member for tightening in the cross-sectional view of the second embodiment of the present invention of Figure 4 (a) and (b) is shown in the operation diagram for reversing the tightened male member As shown in FIG. 1, the nut part 11 is formed on the inner circumferential surface of the arm member 10 and is cut off from the outside to form the pressure chamber 40 and the rotating member 33 fixed to the arm member 10 is not shown.
