Description of the invention (1) [Field of the invention] The present invention relates to a hydraulic inflammation head installed on a processing machine, and particularly to a person who can prolong the service life and avoid the high temperature phenomenon of the chuck from heating up. . [Description of Knowing Skills] "Chuck" is indispensable for clamping the workpiece in the industry to facilitate the processing process of the workpiece; therefore, the chuck is widely used. For example, production line equipment, assembly line equipment, work machine and automation equipment These devices will be used, so in recent years, with the continuous development of production technology, the chucks have also diversified, and a large number of manufacturing has become an accessory of various equipment and work machine. As shown in the first figure, a hydraulic chuck disclosed in U.S. Patent No. 3,073,612 mainly uses the hydraulic pressure to enter the front and rear sides of a piston, and pushes the piston 11 to generate an axial It moves back and forth, and when the piston is moved toward the front side, its front end pushes a thrust bearing, which is displaced, and the thrust bearing 12 abuts on the collet 13 inside the collet, so it can be linked The collet 13 is shifted 'and the jaws 14 on the front side of the collet 1 3 are contracted to sandwich the workpiece for cutting processing. Also, when the piston 11 is shifted to the rear side, the rear end of the piston will push a corresponding The thrust bearing 15 is shifted, and the thrust bearing 15 will push the collet 1 3 ′ again to cause the collet 13 to release the workpiece by releasing the clamping jaw 14. Up to clamp the workpiece for cutting purposes, but there are still defects in practical use that cannot be overcome, that is, the clamping jaw 4 is relatively formed to clamp and loose the workpiece by the displacement of the collet 13 State, and the displacement of the tube cool 1 3 needs to rely on the two thrust bearings 丨 2, 丨 5 as the displacement push page 3 Degree Applicable Towel Closer Standard (CNS) A4 Specification One '... ....., 玎 ...... margin (please read the precautions on the back before writing this page) 557239 A7 B7 V. Description of the invention (2 (Please Read the precautions on the back before filling this page), so the two thrust bearings 1 2, 1 5 will quickly wear with the collet 13 when the hydraulic chuck is constantly operated to clamp the workpiece, so it is quite easy If the damage occurs, the service life of the hydraulic chuck cannot be long. Moreover, the hydraulic chuck that separates the rotating part and the fixed part with thrust bearings 12, 15 is limited to a low speed for the rotation speed that can be driven (about only provides To 100RPM), for today, the processing of precision components is almost impossible to implement, so this type of hydraulic chuck can no longer meet the needs of consumers. As shown in the second figure, US Patent No. 6,1 A hydraulic chuck disclosed in the case No. 73,971 also enters the front and rear sides of a piston 21 by oil pressure to push the piston 21 to generate an axial forward and backward displacement, and when the piston 21 is displaced toward the front side A push block 2 2 on the front end of the piston 21 pushes a bearing 2 3 to shift forward, a push block 24 on the rear end pushes another bearing 25 to shift rearward, and the bearing 23, 25 is abutted on the rotating shaft 26 and a second collet 27 inside the collet, and the rotating shaft 26 is connected to the first collet 28, so the forward displacement of the piston 21 will make the first barrel The clamp 28 and the second collet 27 are indirectly driven to close and clamp the workpiece. Conversely, when the piston 2 丨 is displaced rearward by being driven by oil pressure, the first and second collets 28 and 27 will be indirectly driven and Loose the workpiece, so that the purpose of clamping the workpiece for cutting can be achieved, but this type of hydraulic chuck can control the first and second collets 28, 27 to clamp the workpiece at the same time, and it can be implemented during use Double-sided processing, but it uses the bearings 23, 25 as the first and second collets 28, 27 to shift the push button is a very bad design, the bearings 23, 25 under the lateral thrust, the speed of wear It will be quite fast, and it is prone to eccentric load and burned at high speed, or it may happen under high speed rotation. The service life is not long, and it is very difficult to implement Page 5 557239 A7 "Five, hair" ^ ~-still processing, in addition, the two bearings 23, 25 are provided on the two sides of the piston 21: so the piston 21 and The second collet 27 needs to be provided with a second shaft ㈣ to provide a separation between the rotating part and the fixed part. Therefore, the thickness (shaft length) of the entire hydraulic collet due to the installation of the bearings 23 25 and 29 becomes For a long time, it would be impossible to perform double-sided processing on short workpieces, so that the function of providing double-sided workpieces could not be perfected. As shown in the third figure, a hydraulic chuck, which is commercially available, includes a machine base 31, and a fixed seat 32, a rotating shaft 33, and a detent seat 34 which are pivotally placed in the machine seat 31 in this order. , A clamp slide 35 and a collet ", the rotating shaft" is provided with a number of bearings 33 between its peripheral side and the fixed seat 32, and the fixed seat 32 is identified on the J surface with an oil inlet 3 21, and the rotating shaft 3 3 An oil passage 332 is provided opposite to the oil inlet hole 3 21 and communicates with the side of the detent base 34. When oil pressure flows through the oil inlet hole 321 of the fixed seat 32 and reaches the oil passage 332 of the rotating shaft 33, it can be pushed The detent seat 34 drives the clamp slide seat 35 to shift, thereby inducing the collet% to be in a closed state. In this way, the workpiece can be positioned between the collets 36 to achieve the purpose of clamping and positioning. However, the hydraulic chuck described above Although it has the function of clamping the workpiece to perform the machining operation, but it displaces the driving seat 34 by hydraulic pressure, and the hydraulic pressure will penetrate between the rotating shaft 3 3 and the fixed seat 3 2 and the bearings 3 3 1 It is lubricated inside, but when the collet 36 is clamped, the oil pressure still needs to maintain high pressure to push the stopper 34, so it penetrates into the rotating shaft 33 and the fixed seat. The oil pressure between 32 is still quite high, and it will be disturbed by the bearing 331 to form an oil film 300 between the fixed seat 32 and the rotating shaft 33. When the hydraulic chuck performs processing under the clamped workpiece, the rotating shaft is used. 33 rotation drives the workpiece, so the oil film 300 will be continuously pressed by the friction between the shaft 33 and the fixed seat 32 to generate high heat, and the high-temperature oil viscosity is not the same.

It is impossible to achieve the effect of lubrication, but it will conduct high heat to the components of the hydraulic chuck, so that the service life of the abrasive components such as bearings 33 丨 is shortened. Niu'an even caused the collet 36 to have a high temperature phenomenon, and it was impossible to process some components such as plastics and chain products, which is a major shortcoming in practice. Order-As shown in the fourth figure, 'an improved hydraulic chuck for the occurrence of the high temperature of the collet, mainly through an A oil channel to send oil into the shaft 41 to push a piston 42 in the opposite direction, Then, the collet 43 is driven by the piston 42 to be in a loose state. In addition, the oil is fed into the rotating shaft 41 through a B oil path to push the piston 42 so that the collet 43 can be pushed into a closed clamping state. The collet 43 can be practically extended to extend the length of the body away from the oil pressure into the position between the rotating shaft 41 and the piston 42. When the oil film 400 between the rotating shaft 41 and the piston 42 forms-, it will not be too It can be quickly transmitted to the collet 43, which can reduce the rapid heating condition of the collet 43. However, the friction of the oil film 400 can not be properly solved in this mode, and the high temperature of the oil film 400 is still not reached after use. It will be transmitted to the components of the hydraulic chuck, so components such as bearings (not shown) will also be subject to high heat and quickly wear out. As for the collet 43, shortly after use, the components will be subjected to heat conduction to form high heat. Improve oil film 400 high temperature for processing Impact. SUMMARY OF THE INVENTION Therefore, a first object of the present invention is to provide an oil pressure loss head which does not need to use a bearing as a push button element and can avoid high temperature in the processing state to affect the processing. A second object of the present invention is to provide an oil pressure chuck provided with a cold air unit to cool the oil pressure temperature.

Description of the invention (8) Both sides of the rotating portion 53 have guide slopes 611 and 621 corresponding to the slope 571 of the two-axis cover 57 for driving the detent 56 with oil pressure. It is in a closed state by sliding the guide slopes 611 and 621. When in use, the hydraulic chuck of the present invention is easy to handle. When clamping the workpiece, the oil pressure is first fed through the oil inlet 5 2 2 of the fixed seat 5 2, and then enters the oil chamber 551 of the oil path control valve seat 55 through the oil groove 541 of the sleeve 5 4. Then, with its pressure, the stop ball 5 5 5 blocking the oil inlet valve 5 5 2 is pushed out, and then flows into the oil passage 533 of the rotating seat 53 through the oil outlet groove 542 of the sleeve 54 to push the The detent seat 5 6 is displaced. In this way, the shaft cover 57 fixed on the detent seat 5 6 can be synchronously displaced, and then the inclined surface 571 of the shaft cover 57 is used to relatively drive the first collet 61 to be displaced. The first collet 61 can be closed to hold the workpiece. After the workpiece is clamped by the first collet 61, the oil pressure will be controlled by the circuit board to stop supplying the oil inlet 522. At this time, the stop ball 555 will be moved by the compression spring 554 and the return effect of the oil pressure The oil inlet valve 5 5 2 ′ is sealed, so that the oil in the oil passage 5 3 3 can continue to push the engine base 5 6 at a high pressure. In contrast, the first collet 61 can continue to clamp the workpiece. The oil pressure from the oil inlet 522 to the oil inlet valve 552 is gradually released from the annular gap 5 4 3 between the sleeve 54 and the fixed seat 5 2 into the bearing 5 31 and flows into the bearing 5 31 The oil in the tank will be collected by the oil collecting channel 5 2 4 of the fixed seat 5 2 to the oil collecting chamber 51 3 for recycling. Therefore, when the hydraulic chuck of the present invention is used to process a workpiece, the fixed seat 5 2 and the sleeve 54 do not have a high i pressure, so the temperature rise under the squeeze effect can be relatively reduced. The bearing 5 31 and other abrasion-resistant components will not be quickly damaged by high temperature, and the first and second collets 61 and 62 will not occur.
