[0031] Example 1
[0032] like Figures 1-6As shown, the embodiment discloses a rotatable telescopic clamp mold, which comprises a first cylinder body 100 with a first cavity, an oil pressure base 200 with a second cavity, and a clamp mold assembly. The bottom end of the first cylinder body 100 is connected with the oil pressure base 200, and the first cavity and the second cavity are in communication with each other. The end of the first cylinder body 100 away from the oil pressure base 200 is provided with a first gas channel 120 (the first gas channel 120 is arranged on the top side wall of the first cylinder body 100) communicating with the first cavity and the outside, and the oil pressure base 200 is provided with an oil pressure channel 220 communicating with the second cavity and the outside. The clamp mold assembly comprises a transmission unit and a clamp mold 300. The transmission unit is arranged in the first cavity and the second cavity, and comprises a lead screw 310 and a lead screw seat 320 screwed on the lead screw 310. The first end of the clamp mold 300 is connected with the lead screw 310, and the second end extends to the outside after passing through the first cavity and the second cavity. The first gas channel 120 introduces gas to drive the transmission unit to move, thereby driving the clamp mold 300 to extend to the maximum length. The gas introduced by the first gas channel 120 continues to drive the lead screw seat 320 to slide downward relative to the lead screw 310, thereby driving the lead screw 310 and the clamp mold 300 to rotate forward. The oil pressure channel 220 introduces hydraulic oil to provide a force acting on the clamp mold 300 in the direction of the first cylinder body 100, thereby clamping the workpiece 500.
[0033] As shown, Figure 2 The first cylinder body 100 is also provided with a second gas channel 130 near the end (bottom side wall) close to the oil pressure base 200. The second gas channel 130 is in communication with the first cavity. When it is needed to rotate and retract the clamp mold 300, gas is introduced through the second gas channel 130 to drive the transmission unit to move upward, drive the lead screw seat 320 to slide upward relative to the lead screw 310, thereby driving the lead screw 310 and the clamp mold 300 to rotate reversely, and then drive the clamp mold assembly to move upward, and finally drive the clamp mold 300 to retract to the shortest length.
[0034] As shown, Figure 3 The rotatable telescopic clamp mold further comprises a first rod 330, and the transmission unit comprises a connecting seat 340. The connecting end of the first rod 330 is located in the first cavity, the positioning end 331 of the first rod 330 extends out of the first cylinder body from the end of the first cylinder body away from the oil pressure base 200, and the connecting end of the first rod 330 is fixed to the upper end of the connecting seat 340. The lead screw 310 is fixed to the lower end of the connecting seat 340. The first rod 330 is used for positioning the position of the clamp mold 300.
[0035] As shown, Figure 3As shown, specifically, the first rod member 330 moves synchronously with the transmission unit, a first sensor 332 and a second sensor 333 are arranged on the movement path of the positioning end 331 of the first rod member 330, the first sensor 332 is arranged at the starting point (the highest point) of the movement path of the first rod member 330, and the second sensor 333 is arranged at the ending point (the lowest point) of the movement path of the first rod member 330. When the first sensor 332 senses the positioning end 331 of the first rod member 330, the clamping module 300 is inwards retracted to the shortest length. When the second sensor 333 senses the positioning end 331 of the first rod member 330, the clamping module 300 is outwards extended to the maximum length.
[0036] As shown in the figure, Figure 4 The transmission unit further includes a first push block 350 and a second push block 360, the first push block 350 is sleeved outside the connecting seat 340 and movably connected with the connecting seat 340, the second push block 360 is sleeved outside the first push block 350 and movably connected with the first push block 350, and the first push block 350 and the second push block 360 are both located below the outlet of the first gas channel 120.
[0037] Specifically, the outer diameter of the second push block 360 is the same as the inner diameter of the first cavity, so as to ensure that the outer wall of the second push block 360 abuts against the inner wall of the first cavity, thereby ensuring the stability of the second push block 360 when sliding, and the side of the second push block 360 close to the first push block 350 is provided with a vertical groove, the cross-sectional shape of the first push block 350 is inverted L-shaped, the vertical section of the first push block 350 is inserted into the groove of the second push block 360, the horizontal section of the first push block 350 is overlapped on the top of the connecting seat 340, and the top planes of the first push block 350 and the second push block 360 are flush, thereby increasing the contact area with the gas from the first gas channel 120, and thereby increasing the pushing efficiency.
[0038] Specifically, when the first gas channel 120 introduces the gas, the first push block 350 and the second push block 360 are pushed to move downwards, thereby driving the connecting seat 340, the first push rod, the lead screw 310, the lead screw seat 320 and the third push block 370 to move downwards synchronously. In this process, the lead screw seat 320 does not move relative to the lead screw 310.
[0039] As shown in the figure, Figure 1 , 4 The clamping module 300 includes a moving rod 301 and a clamping block 302, the first end of the moving rod 301 is connected with the bottom end of the lead screw 310, the second end extends to the outside after passing through the oil cylinder seat, and the clamping block 302 is fixed on the second end of the moving rod 301.
[0040] As shown in the figure, Figure 4As shown, further, the first end of the moving rod 301 is sleeved with a pushing bearing 303 and a cylinder piston 304. The cylinder piston 304 is located below the pushing bearing 303 and above the outlet of the oil pressure channel 220. A limiting block 230 is arranged on the inner wall of the second cavity. The pushing bearing 303 is located above the limiting block 230, and the maximum outer diameter of the pushing bearing 303 is greater than the inner diameter of the limiting block 230. When the clamp module 300 is extended outward from the retracted state, gas is introduced through the first gas channel 120. The gas drives the transmission unit, the moving rod 301 and the pushing bearing 303 to move downward synchronously. In this process, the screw rod 310 does not move relative to the screw rod seat 320, and the moving rod 301 does not rotate, until the pushing bearing 303 contacts the upper end of the limiting block 230, and the moving rod 301 reaches the maximum extension length. At this time, the gas from the first gas channel 120 continues to push the second pushing block 360 to move downward, thereby driving the screw rod seat 320 to move downward relative to the screw rod 310, and further driving the screw rod 310 to rotate. The rotation of the screw rod 310 drives the moving rod 301 and the clamping block 302 to rotate. The clamping block 302 rotates 90° in the forward direction, and the clamping block 302 rotates from the state of being parallel to the workpiece 500 to the state of being perpendicular to the workpiece 500.
[0041] When the moving rod 301 reaches the maximum extension length and the clamping block 302 is perpendicular to the workpiece 500, hydraulic oil is introduced from the oil pressure channel 220, thereby driving the cylinder piston 304 and the pushing bearing 303 to move upward, and further driving the moving rod 301 to retract upward. When the cylinder piston 304 abuts against the lower end of the limiting block 230, the clamping block 302 clamps the workpiece 500.
[0042] As shown in Figure 3 The rotatable telescopic clamp module further includes a second cylinder body 400 and two guide rods 410. The second cylinder body 400 is fixedly installed at the end of the first cylinder body 100 away from the oil pressure seat 200, and the second cylinder body 400 is provided with two tracks 420. One end of the guide rod 410 is arranged in the track 420 of the second cylinder body 400 (two guide rods 410 are arranged in two tracks 420 respectively), and the other end extends into the first cavity of the first cylinder and is fixedly connected with the second pushing block 360. That is, when the second pushing block 360 moves linearly, the guide rod 410 also moves linearly synchronously. The arrangement of the guide rod 410 can further increase the stability of the sliding of the second pushing block 360.
[0043] As shown in Figure 4 The rotatable telescopic clamp module further includes a third pushing block 370. The third pushing block 370 is sleeved outside the screw rod seat 320 and movably connected with the screw rod seat 320. The third pushing block 370 is located above the outlet of the second gas channel 130, and the bottom of the third pushing block 370 is a flat surface. When gas is introduced through the second gas channel 130, the third pushing block 370 abuts against the bottom of the screw rod seat 320, thereby driving the screw rod seat 320 to move.
[0044] As shown in Figure 5 the figure shows the mobile rod 301 extended to the longest state, and at this time the clamping block 302 is perpendicular to the workpiece 500, and the clamping block 302 clamps the workpiece 500. Specifically, the clamp is arranged inside the workbench 600, and the workbench 600 is provided with a channel for the mobile rod 301 to extend or retract. When it is necessary to clamp the workpiece 500, gas is introduced through the first gas channel 120, thereby driving the mobile rod 301 to extend and rotate, and then hydraulic oil is introduced through the oil pressure channel 220, which provides the clamping block 302 with a force towards the workbench 600, thereby clamping the workpiece 500.
[0045] As shown in Figure 6 the figure shows the mobile rod 301 extended to the longest state, and at this time the clamping block 302 is perpendicular to the workpiece 500, and the clamping block 302 clamps the workpiece 500. Specifically, the clamp is arranged inside the workbench 600, and the workbench 600 is provided with a channel for the mobile rod 301 to extend or retract. When it is necessary to clamp the workpiece 500, gas is introduced through the first gas channel 120, thereby driving the mobile rod 301 to extend and rotate, and then hydraulic oil is introduced through the oil pressure channel 220, which provides the clamping block 302 with a force towards the workbench 600, thereby clamping the workpiece 500.
[0046] The working process of the rotatable telescopic clamp in this embodiment is as follows:
[0047] When the mobile rod 301 is from the fully retracted state to the fully extended state, gas is introduced from the first gas channel 120, which drives the first push block 350 and the second push block 360 to move downward, thereby driving the connecting seat 340, the first rod 330, the lead screw 310, the lead screw seat 320, the third push block 370, the push bearing 303, the mobile rod 301, the clamping block 302 and the guide rod 410 to move downward synchronously until the push bearing 303 abuts against the top of the limiting block 230, at this time, the mobile rod 301 reaches the longest extended state,
[0048] The gas in the first gas channel 120 continues to drive the second push block 360 to move downward, which drives the lead screw seat 320 to move downward relative to the lead screw 310, thereby driving the lead screw 310, the mobile rod 301 and the clamping block 302 to rotate 90° forward, and the clamping block 302 is perpendicular to the workpiece 500,
[0049] Then hydraulic oil is introduced through the oil pressure channel 220, the pressure of the hydraulic oil drives the oil cylinder piston 304 to move upward, thereby driving the push bearing 303 and the mobile rod 301 to move upward until the oil cylinder piston 304 abuts against the bottom of the limiting block 230, and the oil cylinder piston 304 cannot continue to move upward, the hydraulic oil provides the clamping block 302 with a force towards the workbench 600, thereby clamping the workpiece 500.
[0050] When the moving rod 301 is from the extended state to the fully retracted state, the gas in the second gas channel 130 drives the third push block 370 and the screw rod base 320 to move upward, thereby driving the screw rod 310 and the moving rod 301, the clamping block 302 to rotate reversely by 90°, and the clamping block 302 is parallel to the workpiece 500. In this process, the second push block 360 is inserted into the first push block 350 from bottom to top,
[0051] The gas in the second gas channel 130 continues to drive the third push block 370, the screw rod base 320, the screw rod 310, the first push block 350, the second push block 360, the first rod 330, the second push block 360, the push bearing 303, the moving rod 301, and the clamping block 302 to move upward synchronously until the first push block is sensed by the second sensor 333. At this time, the gas is stopped.
[0052] The clamping module 300 in the embodiment can rotate to clamp or loosen the workpiece 500, and also has the telescopic function. When the workpiece 500 does not need to be clamped, the clamping module 300 can be retracted below the workbench 600, so that the workpiece 500 can be moved on the workbench 600. In addition, the hydraulic oil in the oil pressure channel 220 can provide a force to the clamping module 300 in the direction of the first cylinder body 100, so as to clamp the workpiece 500 on the workbench 600. Then, the guide rod 410 can slide along the track 420 of the second cylinder body 400, and the guide rod 410 is fixed with the second push block 360, which can effectively ensure the stability of the second push block 360 in the sliding process.
[0053] It can be understood that the above embodiments are only exemplary embodiments adopted for illustrating the principles of the present application, and the present application is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present application, and these modifications and improvements are also regarded as the protection scope of the present application.
