Description

Technical Field

[0001] The invention relates to the technical field of power chucks, and in particular to a planetary gear fast-pressing power chuck and a machining machine tool thereof. Background Art

[0002] In general lathe processing, hydraulically clamped power chucks are often used to process parts. These power chucks include two-jaw, three-jaw, four-jaw and other automatic centering chucks. These power chucks can quickly clamp the workpiece and automatically center the workpiece, which greatly reduces the labor intensity of the operator and improves the processing efficiency of parts.

[0003] The Chinese patent discloses "a planetary gear surface double pressure grip positioning fixture" with application number 201810835931.1. The fixture consists of an axial positioning structure and an axially symmetrical locking structure. The axial positioning structure consists of a coaxially connected flange connection plate, a chuck transition plate, a chuck cover plate, a connecting rod, a hinge seat, a chuck inner sleeve, a hinge seat, a positioning pin, and a connecting screw; the axially symmetrical locking structure is a linkage lever mechanism arranged in the axial positioning structure, and the axially symmetrical locking structure consists of pull rods A and B, a pressure claw, a hinge plate, and a retaining spring pin; the connecting screw is an axial motion component, which cooperates with the connecting rod to introduce power, and the pull rod B is connected to the pressure claw through a hinge and forms a linkage body with the pull rod, which is connected and transmitted through the hinge. The axial movement of the pull rod A drives the pull rod B and the pressure claw to axially lock or release the positioning workpiece.

[0004] When the device is processing gears or some mechanical parts, the double pressure claws will automatically and evenly clamp the gears or other mechanical parts. However, when processing the workpiece, it is often necessary to mill or cut the top or the circumference, which will cause obstruction due to the presence of the manipulator, so that the workpiece needs to be fixed in different directions by replacing the chuck during processing to avoid obstruction of the processing part, which greatly reduces the working efficiency.

[0005] Moreover, the temperature of the workpiece itself often rises rapidly during processing. The existing cooling method is to install a nozzle on the milling tool holder, and connect an infusion tube to the nozzle. When the milling cutter operates at a single place, the nozzle discharges liquid to cool that place. This cooling method is local cooling. Since the workpiece has good thermal conductivity, the temperature of its surroundings often rises rapidly during processing. If the surroundings cannot be cooled directly, the cooling rate will be reduced and the consumption of coolant will also increase. Summary of the invention

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See attached Figure 1-Figure 5A planetary gear rapid clamping power chuck and a processing machine tool thereof, comprising a disc body 1, a positioning seat 4 for placing a workpiece is installed on the disc body 1, a plurality of first clamping mechanisms 2 and second clamping mechanisms 3 are respectively arranged on the top and the surrounding side of the positioning seat 4 and are equidistantly distributed, a pull rod 100 is arranged in the disc body 1, and the first clamping mechanism 2 includes a first clamping head 25 located above the positioning seat 4 for clamping the top of the workpiece.

[0031] The first clamping mechanism 2 includes a first pulling rod 21 inserted into the disc body 1, and also includes a connecting rod 22 fixedly connected between the first pulling rod 21 and the pulling rod 100, a mounting seat 23 is fixed on the top of the disc body 1, the first pulling rod 21 passes through the mounting seat 23, and mounting plates 26 are respectively fixed on both sides of the mounting seat 23, and the first clamping mechanism 2 also includes a first clamping block 24, the end of the first clamping block 24 is hinged to the first pulling rod 21, the front end of the first clamping block 24 is hinged between the two mounting plates 26, and the first clamping block 24 includes a first clamping head 25;

[0032] like Figure 2 As shown, it should be noted that the figure shows the state of the pull rod 100 being pushed upward, and the first clamping head 25 in the figure is in the state of clamping the top of the workpiece. Specifically, by pushing the pull rod 100 upward, the pull rod 100 will drive the connecting rod 22 to move upward, thereby pushing the first pulling rod 21 to move upward, so that the end of the first clamping block 24 will be pushed, and then the first clamping block 24 is supported by the mounting plate 26, so that the first clamping block 24 is tilted as a whole. At this time, the first clamping head 25 of the first clamping block 24 will clamp the top of the workpiece.

[0033] The second clamping mechanism 3 includes a mounting plate 31 located in the disk body 1 and fixed on the pull rod 100, and also includes a second clamping block 35 located on the side of the positioning seat 4. The second clamping mechanism 3 also includes a movable block 33, one end of the movable block 33 is a trapezoidal head 300, and the trapezoidal head 300 is movably installed in the mounting plate 31. The end of the movable block 33 is hinged with one end of a second pulling rod 34, and the other end of the second pulling rod 34 is hinged to the end of the second clamping block 35. A mounting frame 37 is fixed on the top of the disk body 1, and the end of the second clamping block 35 is located in the mounting frame 37. The front end of the second clamping block 35 is hinged to the mounting frame 37, and a second clamping head 36 is fixedly installed on the second clamping block 35. A stabilizing component 5 is fixedly installed in the disk body 1, and the end of the second pulling rod 34 is hinged to the stabilizing component 5. A circular movable groove 32 is opened in the mounting plate 31, and the trapezoidal head 300 is located in the circular movable groove 32.

[0034] like Figure 2As shown in the figure, the second clamping head 36 is in an open state without clamping the side wall of the workpiece. It can be seen from the state in the figure that when the pull rod 100 is pushed upward, the first clamping mechanism 2 is in an operating state and the second clamping mechanism 3 is in a non-operating state, so that the operating states of the two are opposite.

[0035] When the second clamping mechanism 3 is operating, the pull rod 100 is pulled downward, so that the mounting plate 31 will drive the trapezoidal head 300 of the movable block 33 to tilt downward, and the end of the movable block 33 will tilt upward, so that the movable block 33 will drive the second pulling rod 34 to move upward, so that the second pulling rod 34 will cause the second clamping block 35 to tilt, so that the second clamping head 36 clamps the side wall of the workpiece.

[0036] The positioning of the workpiece is designed in a diversified manner. The first clamping mechanism 2 and the second clamping mechanism 3 can be operated alternately by moving the pull rod 100, so that the top and the surrounding side of the workpiece can be clamped and fixed separately, so that the top and the surrounding side of the workpiece can be processed separately, avoiding the replacement of different chucks.

[0037] In this embodiment, a pull rod cavity 14 is opened in the disk body 1, and the pull rod cavity 14 includes a movable cavity 9. A guide sleeve 400 is fixed in the disk body 1, and the pull rod 100 passes through the guide sleeve 400 and is located in the pull rod cavity 14. A side cavity 11 located on the peripheral side of the movable cavity 9 is also opened in the disk body 1, and the side cavity 11 is connected with the movable cavity 9. The connecting rod 22 is located in the side cavity 11. A first pulling cavity 10 located next to the side cavity 11 is also opened in the disk body 1, and the first pulling rod 21 is located in the first pulling cavity 10. A circular cavity 8 is also provided in the disk body 1 below the guide sleeve 400, and the mounting plate 31 and the movable block 33 are located in the circular cavity 8. A stabilizing cavity 13 located on the peripheral side of the circular cavity 8 is opened in the disk body 1, and the stabilizing assembly 5 is located in the stabilizing cavity 13. The disk body 1 also has a second pull rod cavity 12 connected with the circular cavity 8, and the second pull rod 34 is located in the second pull rod cavity 12.

[0038] It should also be noted that the stabilizing assembly 5 includes a circular frame 51 fixed in the stabilizing cavity 13, the circular frame 51 is provided with an opening 52, a stabilizing annular rod 53 is fixed in the opening 52, a stabilizing wall 54 is fixed to the end of the movable block 33, and the stabilizing wall 54 and the stabilizing annular rod 53 are hinged, thereby ensuring the stability of the movable block 33 when it moves.

[0039] The second pressing head 36 is provided with a cooling device 500, which includes a nozzle 501 penetrating the second pressing head 36, and also includes a liquid storage chamber 502 located in the second pressing head 36 and connected to the nozzle 501. The cooling device 500 also includes a water retaining assembly for adjusting the water output of the nozzle 501, and the water retaining assembly includes a baffle 504 located at the water inlet end of the nozzle 501 and fixed in position, and the water retaining assembly also includes a movable port 503 opened on the second pressing head 36, and the mounting frame 37 A fixing frame 507 is fixedly installed on the upper surface, a blocking rod 505 penetrating the movable opening 503 is fixed between the baffle plate 504 and the fixing frame 507, a rubber sealing sleeve 506 is provided at the movable opening 503, the second pressing head 36 is provided with a notch 600, the water outlet end of the nozzle 501 is located in the notch 600, an annular water tank 508 is provided at the bottom of the disc body 1, a hose 509 is fixed and connected between the liquid storage chamber 502 and the annular water tank 508, and a micro water pump connected to the hose 509 is provided in the annular water tank 508.

[0040] By moving the nozzle 501 with the movable belt of the second clamping head 36, the top and the surrounding sides of the workpiece can be cooled, the scope of the cooling operation is increased, and the liquid output in different operating areas can be automatically adjusted, thereby improving the utilization rate of the coolant and reducing the amount of coolant used.

[0041] During operation, the pull rod 100 will move in the movable cavity 9, and the guide sleeve 400 will guide the pull rod. When the pull rod 100 is pushed upward, the connecting rod 22 will move in the side cavity 11, the first pull rod 21 will move in the first pull cavity 10, the mounting plate 31 and the movable block 33 will move in the circular cavity 8, and the second pull rod 34 will move in the second pull rod cavity 12.

[0042] Furthermore, by inputting coolant into the annular water tank 508 and starting the micro water pump, the coolant can be input into the liquid storage chamber 502 through the hose 509, and the coolant will be sprayed out through the nozzle 501 to cool the workpiece. When the second pressing head 36 is in operation, Figure 7 As shown, at this time, the nozzle 501 will directly face the peripheral side of the workpiece, thereby cooling the peripheral side of the workpiece. Because the distance between this place and the workpiece is relatively close, in order to prevent the coolant from hitting the peripheral side of the workpiece and causing splashing and waste, at this time, the baffle 504 will block most of the nozzle 501, so that the amount of liquid entering the nozzle 501 per unit time is reduced, and the amount of liquid discharged from the nozzle 501 is reduced, as shown in FIG. Figure 8As shown, at this time, the nozzle 501 will tilt as the second clamping head 36 tilts, and the liquid will directly fall on the top of the workpiece when it is discharged, thereby cooling the top of the workpiece, and the distance between the two becomes farther. Therefore, at this time, the baffle 504 will block a small part of the nozzle 501, so that the liquid intake of the nozzle 501 per unit time becomes larger, and the liquid output of the nozzle 501 increases, which is more suitable for cooling the top of the workpiece.

[0043] In addition, the present invention also discloses a processing machine tool, which is used to install the above-mentioned planetary gear quick clamping power chuck, including a machine tool frame 6, a base 7 is fixedly installed on the machine tool frame 6, a disk body 1 is threadedly installed on the base 7, and a pull rod 100 passes through the base 7 and is fixed to the output end of an external power device. In this embodiment, the power device is a hydraulic cylinder, and an annular water tank 508 is fixedly installed on the base 7.
