Description

Technical Field

[0001] This utility model relates to the field of centering and clamping technology, specifically a cylindrical product clamping device. Background Technology

[0002] When processing products, they need to be centered and clamped. Usually, clamping is done from the outer walls of both sides of the product. Since the outer wall of the columnar part is arc-shaped, clamping from only the two sides is not stable enough. Multi-point clamping is usually used. Although the current clamping device can provide a good clamping effect for the columnar part, it cannot be moved after clamping. When it is necessary to adjust the processing surface of the columnar part during processing, the columnar part needs to be loosened, its position adjusted and then clamped again, which is quite troublesome.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-8 The present invention provides a cylindrical product clamping device, comprising: a cylinder 1 and a mounting plate 2 installed on the inner wall of the cylinder 1, and further comprising: an adjustment component 3 rotatably installed on the top outer wall of the mounting plate 2, a motor 4 installed on the bottom outer wall of the mounting plate 2, and the top of the output shaft of the motor 4 being connected to the bottom of the adjustment component 3, a plurality of equally spaced sliding openings 5 ​​on the top outer wall of the cylinder 1, and a circular block 6 slidably connected to the inner wall of the sliding openings 5, a spring rod 7 movably inserted in the middle of the top outer wall of the cylinder 1, and a placement platform 8 installed on the top of the spring rod 7, the bottom of the spring rod 7 being connected to the adjustment component 3, and arc-shaped grooves 9 at both ends of the top outer wall of the circular block 6, auxiliary components 10 installed on the inner walls of the two arc-shaped grooves 9, and a clamping component 11 installed on the top of the circular block 6.

[0023] It should be noted here that the device can be installed inside the processing equipment 13;

[0024] The columnar component 12 can be placed on the placement platform 8. The motor 4 drives the adjustment component 3, which in turn moves multiple circular blocks 6 towards the columnar component 12 simultaneously. Simultaneously, the adjustment component 3 lowers the spring rod 7, which in turn lowers the placement platform 8, pressing it against the top of the cylinder 1. Multiple clamping components 11 then center and clamp the columnar component 12. When the clamping components 11 are attached to the outer wall of the columnar component 12, the auxiliary components 10 on both sides of the clamping components 11 can adaptively attach to the outer wall of the columnar component 12, further improving clamping stability and ensuring the columnar component 12... The centering and clamping are convenient and quick. When it is necessary to adjust the machining surface of the columnar part 12, multiple clamping components 11 can rotate in the same direction, thereby driving the columnar part 12 to rotate, which makes it easy to adjust its machining surface. There is no need to repeatedly loosen the columnar part 12, adjust its position and then clamp it again, which is more convenient. After the columnar part 12 is machined, the motor 4 drives the adjustment component 3 to drive multiple round blocks 6 to reset, loosening the clamping of the columnar part 12. At the same time, it drives the spring rod 7 and the placement table 8 to rise to a certain height, making it easy to remove the columnar part 12 from the placement table 8.

[0025] In a preferred embodiment, the adjusting assembly 3 includes a threaded rod 301, a nut 302 screwed onto the threaded rod 301, and a plurality of equidistant connecting rods 303 rotatably mounted on the outer wall of the nut 302, with one top end of the connecting rod 303 rotatably connected to the bottom of the corresponding circular block 6.

[0026] It should be noted that: the motor 4 can drive the threaded rod 301 to rotate, which in turn drives the nut 302 to descend, and then pulls multiple round blocks 6 closer to each other through multiple connecting rods 303.

[0027] In a preferred embodiment, the elastic rod 7 includes a sleeve 701, a movable rod 702 slidably connected to the inner wall of the sleeve 701, a first spring 703 sleeved on the outside of the movable rod 702, and a connecting frame 704 installed at the bottom of the movable rod 702; the bottom of the connecting frame 704 is connected to the top of the nut 302.

[0028] It should be noted that: the nut 302 descends by driving the movable rod 702 down through the connecting frame 704, which in turn drives the first spring 703, the sleeve 701 and the placement platform 8 down. The placement platform 8 descends and presses against the top of the cylinder 1. At this time, the multiple clamping components 11 are close to each other but have not yet contacted the outer wall of the column 12. The nut 302 continues to descend, driving the movable rod 702 down and squeezing the first spring 703. The sleeve 701 and the placement platform 8 remain in place.

[0029] In a preferred embodiment, the auxiliary component 10 includes an arc-shaped rod 1001, a slider 1002 sleeved on the outside of the arc-shaped rod 1001, a second spring 1003, and an auxiliary roller 1004 mounted on the top of the slider 1002; the clamping component 11 includes a bending plate 1101, a rotating roller 1102 rotatably mounted on the bottom outer wall of the bending plate 1101, an electric rotary table 1103 mounted on the top of the bending plate 1101, and a rubber sleeve 1104 mounted on the outer wall of the rotating roller 1102, wherein the rotating part of the electric rotary table 1103 is connected to the top of the rotating roller 1102.

[0030] It should be noted that: multiple circular blocks 6 approach each other, thereby driving multiple rotating rollers 1102 to approach and press against the outer wall of the columnar member 12, clamping the columnar member 12. The auxiliary rollers 1004 on both sides of the rotating rollers 1102 also press against the outer wall of the columnar member 12, and drive the corresponding sliders 1002 to move, squeezing the second spring 1003. The reaction force of the second spring 1003 is used to press the auxiliary rollers 1004 against the outer wall of the columnar member 12, further improving the clamping stability. When it is necessary to adjust the processing surface of the columnar member 12, multiple electric rotary tables can simultaneously drive the corresponding rotating rollers 1102 to rotate in the same direction, thereby driving the columnar member 12 to rotate, which facilitates the adjustment of its processing surface.

[0031] Working principle: The columnar part 12 can be placed on the placement platform 8. The motor 4 can drive the threaded rod 301 to rotate, which in turn drives the nut 302 to descend. Then, through multiple connecting rods 303, multiple round blocks 6 are pulled closer to each other, which in turn drives multiple rotating rollers 1102 to press against the outer wall of the columnar part 12, clamping the columnar part 12. The nut 302 descends through the connecting frame 704, which drives the movable rod 702 to descend, which in turn drives the first spring 703, the sleeve 701 and the placement platform 8 to descend. The placement platform 8 descends and presses against the top of the cylinder 1. At this time, the multiple rotating rollers 1102 are close to each other but have not yet contacted the outer wall of the columnar part 12. The nut 302 continues to descend, driving the movable rod 702 to descend and squeeze the first spring 703. The sleeve 701 and the placement platform 8 remain in place.

[0032] Multiple rotating rollers 1102 press against the outer wall of the columnar member 12 to clamp the columnar member 12. The auxiliary rollers 1004 on both sides of the rotating rollers 1102 also press against the outer wall of the columnar member 12 and drive the corresponding sliders 1002 to move, squeezing the second spring 1003. The reaction force of the second spring 1003 is used to press the auxiliary rollers 1004 against the outer wall of the columnar member 12, further improving the clamping stability. When it is necessary to adjust the processing surface of the columnar member 12, multiple electric rotary tables can simultaneously drive the corresponding rotating rollers 1102 to rotate in the same direction, thereby driving the columnar member 12 to rotate, which makes it convenient to adjust its processing surface. There is no need to repeatedly loosen the columnar member 12, adjust its position and then clamp it again, which is more convenient.

[0033] After the columnar part 12 is processed, the motor 4 drives the threaded rod 301 to rotate in the reverse direction, which in turn drives the nut 302 to rise, which in turn drives the multiple round blocks 6 to reset, loosening the clamp on the columnar part 12. At the same time, it drives the movable rod 702 to rise, which in turn drives the sleeve 701 and the placement table 8 to rise to a certain height, so that the columnar part 12 can be taken off the placement table 8.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
