Description

A DELICATE OPERAIING TOOL ASSEMBLY The present invention relates to a delicate operating tool assembly suitable for a user to inlay a diamond or install fine parts.

Delicate precious jewelry such as a diamond ring, diamond bracelet, diamond watch, etc. is preferably manufactured manually to show its noble value. However, the manual manufacturing procedure is quite complicated. Particularly, as shown in Fig. 30, it is difficult to install a small diamond or fine parts and much time is wasted in such a procedure. In a conventional procedure, an article to be inlaid with a diamond is first drilled with a hole for the diamond.

Then the operator blows away the small particles or dust in the hole with the mouth. Thereafter, the operator uses a pair of forceps to pick up fine parts and lay the same into the hole. Such a movement is difficult to carry out, In the case where the diamond is misplaced, the diamond will have to be removed again, and it is difficult to do so with conventional forceps.

Therefore, an easily operable tool for accomplishing the above task is indeed desirable Moreover, conventional diamond inlaying working frames can be divided into two types. The first type works in such a manner that the article to be inlaid is attached to a lead ball with a handle. The second type works in such a manner that the article to be inlaid is fitted with a bamboo section pipe which is fixed to a working stand with an extending plate so that the operator can lean against the extending plate and hold the inlaying seat to inlay the diamond. Many drawbacks exist in such working frames. For example, if the article to be inlaid is placed on a bamboo section pipe, the inlaying angle will be greatly limited.When the diamond is desired to be inlaid at a lower inclined angle, if the operator leans against the extending plate the inlaying seat is apt to slip away and cause injury of the operator's hand. Furthermore, when inlaying a diamond on a conventional working stand, the left hand is used to hold the handle, and the right hand is used to pick up the diamond and place the same into the inlaying hole. Then the right hand is used to hold a sharp tool to work on the diamond. grh a procedure is quite labor- intensive and time-wasting and is verv dangerous. In addition, the sizes of the bamboo section pipes are different from one another so that different feelings occur in different operatiors. As a result, the work quality is greatly affected. Therefore, a safe, conveniently operable and labor-saving working frame is still required.

It is considered advantageous in the present invention provide a delicate operating tool assembly employing a specifically designed vacuum pump to provide sucking/blowing force, which is transmitted to a handheld sucking/blowing operating tool via a hose for clearing off small particles or sucking fine parts for installation.

It is further advantageous to provide the above operating tool assembly which can perform the functions of picking, placing and blowing without replacing different tools so that operating time is greatly reduced.

It is still further advantageous to provide the above operating tool assembly with a switch valve enabling the user to easily control the sucking and blowing functions of the nozzle.

It is still further advantageous to provide the above operating tool assembly with a pressing needle located beside the nozzle so that if a fine part is blocked, the pressing needle can pick out the fine part for relocation. The present invention further has a universal working frame, permitting the user to install the fine parts in multiple directions.

Please first refer to Fig. 1. The present invention includes an operating tool 1, a double hose 2, a vacuum pump 3 and a universal working frame 4, wherein the vacuum pump 3 has a suction opening and a discharge opening, which are connected to the operating tool 1 via the double hose 2.

Referring to Figs. 2, 3, and 4, the operating tool 1 includes an upper handle 11, a blowing/sucking switch valve 12 and a lower nozzle 13, wherein the handle 11 is arch-shaped for a user to hold and formed with a tunnel 111. A bearing 113 is disposed at upper end of the handle 11 and a sleeve 114 is rotatably fitted in the bearing 113. The sleeve 114 has a flange 1141 clamped by a clevis 112 and a pipe portion 1142 protruding beyond the upper end of the handle 11 to fit with an outer hose 21 of the double hose 2 connected to the suction and discharge openings of the vacuum pump 3.

An inner hose 22 of the double hose 2 goes through a central hole 1143 of the sleeve 114 into the tunnel 111 of the handle 11. The lower end of the handle 11 is formed with a thread portion 115 suitable to joint with the switch valve 12.

The blowing/sucking switch valve 12 includes a connecting member 121 having an upper inner thread 1211 suitable to screw on the thread portion 115 of the handle 11. A sealing ring 122 is located therebetween to prevent leaking. A through hole 1212 is formed on the middle portion of the connecting member 121. A switch pin 123 and a restoring spring 1235 are placed in the through hole 1212. As shown in Figs. 4, 5, the upper edge of the switch pin 123 is formed with three holes 1231, 1232, 1233. The left hole 1231 has an upper slot-like opening 12311 whereby an insert pin 1215 can axially extend from the inner thread 1211 thereinto for guiding the switch pin 123 and preventing the same from rotating. The left hole 1231 has a lower opening 12312.

The middle hole 1232 of the switch pin 123 extends forward to communicate with a transverse groove 1234.

The right hole 1233 is a straight through hole. The lower portion of the connecting member 121 is formed with an inner thread 1213 to joint with a nozzle 13. A T-shaped pipe 124 is disposed in the upper inner thread 1211. A lower ring 1241 of the T-shaped pipe 124 has a recess 1243 so that the insert pin 1214 can go therethrough and a first orifice 12511 is in an open state, as shown in Fig. 8. The stem portion 1242 of the T-shaped pipe 124 is fitted with the end of the inner hose 22 and communicated with a second orifice 1252. A third orifice 1253 is formed at the end of the through hole 1212 of the connecting member 121 to communicate with the middle hole 1232 of the switch pin 123 and with the groove 1234. The first and second orifices 1251 and 1252 penetrate through the walls above the middle hole 1232.

The nozzle 13 has a main body 131 formed with an upper thread pipe 1311 to screw in the inner thread 1213 of the connecting member 121 of the switch valve 12.

The central portion of the main body 131 is formed with an upper chamber 1312 with larger diameter for receiving a filter net 132. The lower portion of the main body 131 is formed with an outer thread pipe 1313 to screw in an inner thread pipe 1331 of an injection pipe 133. A pressing needle 134 is disposed at the conjunction between the inner thread pipe 1331 and the injection pipe 133 for the convenience of working.

When operating, the end of the outer hose 21 of the double hose 2 is connected to the discharge opening of the vacuum pump 3 and the inner hose 22 is connected to the suction opening thereof. Therefore, as shown in Fig. 6, when the switch pin 123 is not pressed in, the right hole 1233 thereof is connected between the upper chamber 1312 of the nozzle and the second orifice 1252 so that the sucked air flow can go through the nozzle 13, enabling the injection pipe 133 to suck fine parts. While a discharged air flow goes through the outer hose 21 and passes from the first orifice 1251 through the middle hole 1232 and groove 1234 toward the third orifice 1253 to be discharged therefrom.

Moreover, as shown in Fig. 7, when the switch pin 123 Is axially pushed (as indicated by arrow in Fig. 7) to compress the spring 1235, the switch pin 123 will be guided via the insert pin 1214 and the slot-like opening 12311 of the left hole 1231 to move inward. At this time, the discharged air flow goes from the outer hose 21 through first orifice 1251, through hole 12312 and the upper and lower chambers 1312 1313 to discharge from the injection pipe 133, enabling the injection pipe 133 to blow away small particles. Simultaneously, a sucking force is created in the stem portion 1242 of the Tshaped pipe and the air is sucked into the third orifice 1253 to pass through the groove 1234 and second orifice 1252 into the stem portion 1242.

When used, the switch pin 123 is first pressed to enable the injection pipe 133 to blow out an air flow so as to clear off small particles in a drill hole of a diamond. Then the switch pin 123 is released to enable the injection pipe 133 to suck air in so as to pick up fine parts for installation. After the fine parts are installed, the switch pin 123 can be slightly pressed to eliminate the sucking force of the injection pipe 133, permitting the fine parts to fall in place. Thus, the installation of a fine part is completed.

The pressing needle 134 disposed at the conjunction between the inner threadedpipe 1331 and the injection pipe 133 is used to press the fine part into a fixed position and facilitate the installation. A second sealing ring 1221 is disposed between the lower ring 1241 of the T-shaped pipe 124 and the lower end of the handle 11 to prevent leaking.

The diameter of the injection pipe 133 can be varied in accordance with different work pieces.

Please now refer to Figs. 9, 10 and 11. The vacuum pump 3 of this invention includes an in-coming room 311, an out-going room 312, a rcdd# arm 313 with a magnet 3131, an expanding member 314, a membrane 315, a diaphragm 316 and other necessary members. As shown in Fig. 9, a coil 317 is used to produce a magnetic force to push and pull the magnets 3131 and make the rock arms 313 swing left and right. As a result, the expanding member 314 will continuously suck air through an inlet 3112 into the in-coming room 311 and discharge air from the out-going room 213 outside an outlet 3122.

As shown in Figs. 12 and 13, on the wall 3111 of each of the in-coming room 311 and out-going room 312 is formed with four membrane fixing seats al, a2, a3 and a4, which are arranged into an upper and a lower pairs each of which are located inside and outside the wall 3111. The upper pair of fixing seats a3, a4 have a mutual opening pl while the lower pair of fixing seats a3, a4 have a mutual opening p2. A fixing block 3151 presses and fixes the membrane 315 in the fixing seat, as shown in Fig. 10, making a movable portion of the membrane 315 cover the opening.

Moreover, the diaphragm 316 is designed to downward extend toward the lower fixing seat a3 and formed with an air hole 3161 in alignment with the second opening p2 for air to flow therethrough.

Further referring to Fig. 14, after assembled, the membrane 315 is disposed on the upper fixing seat a2 outside the in-coming room 311 to cover the outer side of the first opening pl. Also, another membrane 315 is disposed on the lower fixing seat a3 to cover the inner side of the second opening p2. A membrane 315 is disposed on the upper fixing seat al inside the outgoing room 312 to cover the inner side of the first opening pl and another membrane 315 is disposed on the lower fixing seat a4 to cover the outer side of the second opening p2. Therefore, as indicated by the arrows in Fig. 14, when the coil 317 is powered on, the right rock arm 313 first pulls the expanding member 314 left, making air sucked into the inlet 3112 of the incoming room open the membrane 315 on the fixing seat a2. The air then flows through the first opening pl of the in-coming room. Then the right rocking arm 313 moves left, making the air in the in-coming room 311 flow out from the second opening p2 and pass through the air hole 3161 of the diaphragm 316 into the out-going room 312.

Then the left rocking arm 313 moves left to open the membrane located on the fixing seat a4, and air flows into the second opening. Then the left rocking arm 313 moves right, making the air pass through the first opening pl of the out-going room 312 and discharge from the outlet 3122 to complete a close air circulation.

It should be noted that the walls of the inlet and outle 3112, 3122 are symmetrically semicircularly shaped so that they can co-operate with each other to form a cylindric pipe as shown in Fig. 11 to connect with the double hose 2 (as shown in Fig. 14).

Moreover, the in-coming room and out going room 311, 312 are specifically designed and are the same in appearance for easy manufacture. Furthermore, since the air circulation is a closed loop, the suction/discharge force is greatly raised.

A universal working frame is necessary for the operation of the above assembly. Referring to Figs. 15 and 16. The working frame includes a fixing base 47 mounted on a working stand 9. The fixing base 47 includes a bent fixing plate 471 and a connecting plate 472 formed with multiple thread holes 4721. The bent fixing plate 471 is secured on the working stand 9 by screws 4711 and the connecting plate 472 is fastened to the bent fixing plate 471 by means of a dovetail and screws 4722 to achieve more firm connection.

The frame body 41 at least includes a one-way fixing rod 411, one-way rotary rod 412, universal connecting rod 413 and a universal rotary fixing rod 414 for fixing an inlay seat, wherein the one-way fixing rod 411 has a thread portion 4111 for securing the frame body 41 to the thread hole 4721 of the connecting plate 472. The one-way rotary rod 412 is pivoted to the oneway fixing rod 41 in such a manner that a bolt 4121 goes through a bolt seat 4122 to associate with a hole seat 4112 of the fixing rod 411 so that the rotary rod 412 can rotate in one direction relative to the fixing rod 411. The assembly thereof is shown in Fig. 13. The one-way rotary rod 412 is connected to the universal connecting rod 413 by means of a thread rod 4123 screwing in an inner thread hole 4131 of the connecting rod 413.The universal connecting rod 413 has a ball seat 4132 fitting with a ball member 4141 of the fixing rod 414, as shown in Fig. 18, so that the fixing rod 414 can universally rotate relative to universal connecting rod 413. A ring seat 4142 is formed at the front end of the fixing rod 414 so that a handle 42 mounted with the piece to be inlaid can be placed therein, as shown in Fig. 19.

It should be noted that in the frame body, a second one-way rotary rod 412 can be additionally disposed between the one-way fixing rod 411 and one-way rotary rod 412 so that the frame body can rotate in a horizontal plane and a vertical plane. As shown in Fig.

19, a handle 42 mounted with a ring to be inlaid is located, while as shown in Fig. 20, a general piece to be inlaid is located.

Please refer to Figs. 21 through 23, which show the application of two frame bodies, wherein the frame body 41 is without second one-way rotary rod 412 while frame body 41' is with the second one-way rotary rod 412. Therefore, when used, the two frame bodies 41, 41' can be disposed in parallel (as shown in Fig. 21) or in cross pattern (as shown in Fig. 22) or in a double cross pattern as shown in Fig. 23. Therefore, the working can be performed in multiple directions. Particularly, when performing diamond inlaying, the operator only needs to exert a downward force and the frame body will bear all the force so that a great deal of labor is saved.

Please refer to Figs. 25 through 28, which show an example of the fixing base 47, wherein the fixing base 47 includes a bent fixing plate 4711 and a connecting plate 4712 formed with multiple thread holes. As shown in Figs. 25, 26, the bent fixing plate 4711 is secured on the edge 91 of the working stand 9 by screws 4711 going through the circular holes 47113 of the horizontal portion 47112. A dovetail 47115 and thread holes 47116, 47117, 47118 are formed on the vertical portion of the bent fixing plate 4711, wherein the thread hole 47117 is formed on the central portion of the dovetail 47115. The connecting plate 4712 is formed with a dovetail groove 47129 corresponding to the dovetail 47115 and several thread holes 47121 are formed on the upper half portion of the connecting plate 4712 for connecting with the frame body.Three through holes 47122, 47123, 47124 are formed on the lower portion of the connecting plate 4712, wherein the through hole 47123 is upward elongated to form a slot 47123. By means of the dovetail and screws 47125 going through the through holes 47122, 47123, 47124 to screw in the thread holes 47116, 47117, 47118 the connecting plate 4712 is firmly fastened to the bent fixing plate 4711.

To meet the various requirements of different operators, a screw 47125 can go through the slot 47123 to screw in the central thread hole 47117 of the dovetail 47115 of the fixing plate 471, permitting the connecting plate 472 to move relative to the fixing plate 471 to adjust the height of the connecting plate 4711.

In addition, the switch valve of the operating tool 1 can be removed as shown in Fig. 29. A sleeve 511 is disposed at the upper end thereof to fit with the double hose 2. The main body 512 of the sucking/discharging device :is hollow so that air flow can easily flow in and flow out. A bearing 513 is disposed between the sleeve 511 and main body 512 so that the main body 512 can rotate relative to the sleeve 511. A sharp nozzle head 514 is formed at the lower end of the main body so as to create a narrow neck effect for reinforcing the sucking/discharging force provided by the double hose 2.

When operating, the rubber membranes of the vacuum pump 3 can be arranged into double pattern to connect the double hose 2 to the sucking/discharging device 51.

If two sucking/discharging devices 51 are respectively connected to the inlet 31 and outlet 32 of the vacuum pump 3, then the two devices can be operated simultaneously by two operators, wherein one operator can first perform blowing operation to clear off small particles and then the other operator can perform sucking operation to complete inlaying of the diamond.

This procedure is quite simple and the manufacturing time is reduced.

The present invention can be variously modified without departing from the scope thereof.
