[0042] In this embodiment, the mounting seat is the upper cover 150 of the clamping device, and the upper cover 150 is cross-shaped. Of course, in other embodiments of the present invention, the upper cover may also be square, Round and other shapes. In this embodiment, the upper cover 150 has four upper arms 151 extending around, and the 4 upper arms 151 are evenly distributed within a range of 360°, and the angle between adjacent upper arms 151 is 90 degrees. In addition, in other embodiments of the present invention, the number of the upper support arms may also be other numbers, such as 2, 6, and so on. In addition, in other embodiments of the present invention, the mounting seat may also be the bottom cover of the clamping device.
[0043] In this example, see Figure 5-Figure 11 A plurality of the sliding bodies 120 are formed on a mounting seat, where "upper" means above. In fact, the mounting seat is above the plurality of sliding bodies 120. In this embodiment, the number of the plurality of sliding bodies 120 is four, and the number of the sliding bodies 120 is the same as the number of the upper support arms 151, and each of the four upper support arms 151 A sliding body 120 is fixed on the 151, and the extending direction of the sliding body 120 is consistent with the extending direction of the upper arm 151, and the four sliding bodies 120 are evenly distributed in the range of 360 degrees. In this embodiment, the sliding body 120 includes a sliding rail 121, and the sliding body 120 is in an inverted T shape. In addition, in other embodiments of the present invention, the sliding body includes a sliding groove. In addition, in other embodiments of the present invention, the number of the sliding bodies is not limited to four, and may also be other numbers, such as two, six, etc. In this embodiment, the central axes of two opposite sliding bodies 120 are located on the same straight line. In addition, in another embodiment of the present invention, the two relative sliding bodies can be connected as one body.
[0044] In this embodiment, a plurality of clamping members 200 are respectively mounted on different sliding bodies 120. In this embodiment, one sliding body 120 is provided with a clamping member 200, and the number of the clamping members 200 is 4. Each of the clamping members 200 can slide on the corresponding sliding body 120, specifically sliding on the corresponding sliding rail 121. In this embodiment, the clamping member 200 can slide along the outside of the sliding body 120 to the inside of the sliding body 120, of course, the reverse is also possible. In this embodiment, when the size of the piece to be clamped is small, a plurality of the clamping members 200 can respectively slide to the vicinity of the inner end of the sliding body 120 to jointly clamp the piece to be clamped, and the joint force can be When the size of the piece to be clamped is large, the plurality of clamping members 200 can respectively slide to the vicinity of the outer end of the sliding body 120 to clamp the piece to be clamped together. The common force It can be either outward or inward; when the size of the piece to be clamped is in the middle size, a plurality of the clamping members 200 may be respectively located between the outer end and the inner end of the sliding body 120 to jointly clamp the piece to be clamped. Clip. Therefore, the clamping device of the embodiment of the present invention can clamp parts to be clamped of different sizes. In this embodiment, the part to be clamped may be an inner container, a pot, a tire, a kettle, a cup, etc. The shape of the part to be clamped is not limited, and may be a circle, a square, a polygon, etc., such as When the part to be clamped is an inner liner, when the size of the inner liner is an intermediate size, the four clamping elements 200 can act on the outer wall of the liner to clamp the inner liner (the force is inward at this time), Or the four clamping members 200 can also act on the inner wall of the inner liner to clamp the inner liner (in this case, the force is outward).
[0045] In order to make the different clamping parts 200 slide on the different sliding bodies 120 in linkage to clamp the parts to be clamped quickly, see Figure 6-Figure 9 In this embodiment, the linkage cable 130 is respectively linked to the clamping member 200, where the linkage connection means that when the linkage cable 130 slides, the clamping member 200 also slides along with the linkage cable 130, so The linkage cable 130 drives the clamping member 200 to slide on the respective sliding body 120. In this embodiment, the linkage cable 130 is connected end to end, that is, the linkage cable 130 is closed. Therefore, when the linkage cable 130 moves at one point, the linkage cable 130 will move as a whole, and the linkage cable 130 will drive all the clamping members 200 to slide, thereby adjusting the size of the clamping members 200 The size of the area, which can be suitable for clamping pieces to be clamped of different sizes. In addition, when one of the clamping members 200 moves, the clamping member 200 can also drive the linkage cable 130 to move, thereby driving the other clamping members 200 to move, and it is also possible to adjust a plurality of the clamping members 200 to form The size of the area. In this embodiment, the linkage cable 130 drives the four clamping members 200 to slide outward or slide inward as a whole.
[0046] In order to make the plurality of clamping members 200 slide outward or slide inward as a whole, the linkage cable 130 needs to slide along a predetermined path. In this example, see Figure 5-Figure 9 , The clamping device further includes a plurality of limiting members 140, the plurality of limiting members 140 are installed on the mounting seat, and the linkage cable 130 is wound on the plurality of limiting members 140 to make the The linkage cable 130 slides along a predetermined path. In this embodiment, the portion of the linkage cable 130 that is wound on the limiting member 140 is U-shaped. In this embodiment, the number of the limiting members 140 is 12, and three limiting members 140 are arranged near each sliding body 120. Of course, in other embodiments of the present invention, the number of the limiting members may also be other numbers, and the number of the limiting members arranged near each sliding body may also be other numbers. In this embodiment, the limiting member 140 is a fixed pulley, a bearing or a shaft sleeve, etc., and the manner in which the limiting member 140 is positioned on the mounting seat is a common technical knowledge in the art, and will not be repeated here. In this embodiment, the linkage cable 130 is wound on a fixed pulley, a bearing or a shaft sleeve. When the linkage cable 130 moves, the linkage cable 130 will drive the fixed pulley, the bearing or the shaft sleeve to rotate. In addition, in other embodiments of the present invention, the limit member may also be a limit post, the limit post is fixed on the mounting seat, and the linkage cable is wound on the limit post. When the linkage cable moves, the linkage cable slides on the limit post, and the limit post itself does not rotate.
[0047] In order to smoothly enable the linkage cable 130 to drive the clamping member 200 to slide on the respective sliding body 120, and to reduce the resistance of the clamping member 200 when sliding. In this example, see Figure 7 with Figure 8 Among the three limiting members 140 adjacent to each sliding body 120, two of the limiting members 140 are located at both ends of the corresponding sliding body 120, specifically located at the inner and outer ends of the sliding body 120, which are called adjacent sliding The limiting member 140 at the outer end of the main body 120 is called the outer limiting member 141, the limiting member 140 adjacent to the inner end of the sliding body 120 is called the inner limiting member 142, and the clamping member 200 on the sliding body 120 is located at the inner limiting member The part of the linkage cable 130 between 142 and the outer limiter 141 and between the two limiters 140 is parallel to the central axis of the sliding body 120, specifically in this embodiment is the sliding rail of the sliding body 120 The central axis of 121 is parallel, that is, parallel to the straight line formed by the sliding path of the clamping member 200 on the sliding body 120, and the part of the linkage cable 130 between the inner and outer limit members 140 and the sliding body 120 The clamping member 200 is fixedly connected, where the two are connected together by screws to make the linkage cable 130 and the clamping member 200 move together. Therefore, since the part of the linkage cable 130 between the inner and outer limit members 140 is parallel to the central axis of the sliding body 120, when the linkage cable 130 moves, the pulling force of the clamping member 200 on the sliding body 120 is similar to that of the sliding body. The directions of the central axes of the 120 are parallel, so that the clamping member 200 receives less resistance when sliding on the sliding body 120, so that the resistance received when the linkage cable 130 moves can be reduced. In this embodiment, the outer limiting member 141 and the inner limiting member 142 can define the maximum distance that the clamping member 200 slides outward and inward. In addition, in this embodiment, the other one of the three limiting members 140 adjacent to the sliding body 120 functions to guide the steering of the linkage cable 130 so that the linkage cable 130 moves in a predetermined direction and path. , The outer limit member 141 and the inner limit member 142 also have the function of guiding the linkage cable 130. In addition, in other embodiments of the present invention, the number of stoppers adjacent to each sliding body may also be 2, 4 or more.
[0048] In order to make the clamping member 200 slide on the sliding body 120, see Figure 7 , Figure 9-11 In this embodiment, the sliding body 120 is in an inverted T shape, and the clamping member 200 is provided with a corresponding concave groove 211, and the concave groove 211 cooperates with the sliding body 120 to make the The clamping member 200 slides on the sliding body 120. In this example, see Figure 1-Figure 11 The clamping member 200 includes a sliding block 210 and a clamping jaw 220. The upper surface of the sliding block 210 is provided with the concave groove 211, and the sliding block 210 is slidably connected to the corresponding sliding body 120. In this embodiment, the concave groove 211 of the slider 210 wraps up the sliding body 120 from below, and the clamping jaw 220 is directly or indirectly fixed on the slider 210. In addition, in other embodiments of the present invention, the sliding body does not include a sliding rail, but includes a sliding groove, and the sliding block slides in the sliding groove.
[0049] In this embodiment, in order to make the front (upper surface) of the clamping device more beautiful, the clamping member 200 further includes an intermediate piece 230, and the bottom of the intermediate piece 230 and the slider 210 are screwed together. Fixed connection (see figure 2 , Figure 5 ), the clamping jaw 220 and the upper surface of the intermediate piece 230 are fixedly connected by screws. Therefore, when the sliding block 210 slides on the sliding body 120, the sliding block 210 drives the intermediate piece 230 to move synchronously through the screw, and the intermediate piece 230 drives the clamping jaw 220 to move synchronously, thereby realizing clamping The inside and outside of the claw 220 are moved so as to realize that the clamping claw 220 is located at different positions. When the clamping claw 220 is located at different positions, it can clamp parts to be clamped of different sizes and sizes. In this embodiment, the clamping jaw 220 may be L-shaped, cylindrical, or the like, and the shape of the contact portion of the clamping jaw 220 with the part to be clamped matches the shape of the part to be clamped.
[0050] In this example, see figure 2 , Figure 5 , Image 6 The clamping device further includes a bottom cover 110, the bottom cover 110 is fixedly connected to the upper cover 150, and the bottom cover 110 covers the mounting seat (upper cover 150) from below. In this embodiment, the bottom cover 110 is also cross-shaped. Similarly, the bottom cover 110 has four lower arms 111. In this embodiment, the lower arm 111 and the upper arm 151 both pass through the corresponding square-shaped middle piece 230, so that the clamping jaw 220 is located on the middle piece 230, and the upper The upper surface of the cover 150 does not need to be digged to affect the appearance.
[0051] In order to achieve a fixed connection between the intermediate piece 230 and the slider 210, in this embodiment, the lower support arm 111 is provided with a strip hole 112, and in this embodiment, each lower support arm 111 is The number of the strip-shaped holes 112 is 2 or other numbers, the middle piece 230 is fixedly connected to the slider 210 by screws, and the screws are fixed to the slider 210 through the strip-shaped holes 112 Thus, the middle piece 230 is fixedly connected to the slider 210 from the bottom by screws. In addition, in this embodiment, the strip hole 112 on the lower arm 111 can limit the maximum distance that the clamping member 200 slides outward and inward through screws.
[0052] In this example, see Figure 6-Figure 8 The linkage cable 130 may be a steel wire, a steel wire rope, a nylon rope, etc. The number of the linkage cable 130 including a steel wire, a steel wire rope, and a nylon rope may be one or multiple, and in this embodiment, there are two. The use of the linkage cable 130 can greatly reduce the cost of the clamping device. Moreover, because the linkage cable 130 can be designed to be very long, the pieces to be clamped can be relatively large, that is, the clamping device has a wide range of application scenarios; moreover, the linkage cable The 130 itself is relatively light and smooth to use, and it does not require much effort to adjust the position of the clamp 200. In addition, in this embodiment, the head and tail ends of the linkage cable 130 are connected. At this time, the linkage cable 130 is fully utilized, no additional space is required, no additional linkage cable 130 length is required, and adjustment and clamping are achieved. The location of the piece 200 is relatively flexible and simple. In addition, in other embodiments of the present invention, the linkage cable may not be connected at the end.
[0053] In this embodiment, according to the shape of the piece to be clamped, the position of the clamping piece 200 on the linkage cable 130 can be calculated. In this embodiment, please refer to Figure 4 , When the piece to be clamped is circular, at this time, a plurality of the clamping pieces 200 are arranged on the circumference of the circle, that is, the clamping piece 200 slides in a position of the sliding body 120 through the linkage cable 130 When the four clamping members 200 are on the same circle at this time, when the clamping member 200 slides to another position of the sliding body 120 through the linkage cable 130, the four clamping members 200 are The piece 200 is on the circumference of another same circle. A plurality of the clamping members 200 are evenly arranged. In the present embodiment, the number of the clamping members 200 is four. At this time, the distance between two adjacent clamping members 200 is equal, and each is separated by 1/4 The arc length. In addition, when the shape of the piece to be clamped is square, at this time, multiple clamping pieces are on the same square circumference.
[0054] In order to adjust the position of the clamping member 200 on the sliding body 120, in this embodiment, the user can manually move one of the clamping members 200 to move, so that the clamping member 200 drives the other clamping members through the linkage cable 130. The member 200 moves to adjust the size of the area enclosed by the plurality of clamping members 200. However, the present invention is not limited to this. In other embodiments of the present invention, the clamping device further includes a driving member, for example, a motor, and the driving member can drive one of the clamping members on the corresponding sliding body. Upward movement, such as outward movement or inward movement, when the driving member drives one clamping member to move, the driven clamping member drives other clamping members to move through the linkage cable, thereby automatically adjusting the area enclosed by the clamping member Therefore, it is possible to clamp parts to be clamped of different sizes, which is beneficial to the automation of the clamping device.
[0055] In addition, in this embodiment, the clamping device further includes a mounting post 160 that is fixed at the bottom of the mounting base (bottom cover 110), and the mounting post 160 mounts the mounting base to Other platforms, such as spraying platforms.
[0056] In addition, an embodiment of the present invention also provides a clamping system. The clamping system includes a piece to be clamped and a clamping device. The clamping device is the above-mentioned clamping device, and the clamping device clamps the waiting device. Clip. In this embodiment, the clamping member 200 of the clamping device can press against the outer wall or the inner wall of the member to be clamped to position the member to be clamped.

Example

[0057] Second embodiment
[0058] Picture 12 Is a schematic diagram of a clamping device in the second embodiment of the present invention, Picture 12 Schematic diagram with figure 1 The schematic diagrams are similar, so the same component symbols represent the same components. The main difference between this embodiment and the first embodiment is the shape and structure of the clamping device.
[0059] See Figure 12-15 In this embodiment, the clamping device is circular as a whole, specifically the upper cover 350 and the bottom cover 310 are both circular. In this embodiment, the mounting seat is the bottom cover 310 of the clamping device, and four sliding bodies 320 are provided above the bottom cover 310. Of course, in other embodiments of the present invention, the sliding The number of bodies can also be other numbers, such as 2, 6, etc. In this embodiment, the four sliding bodies 320 are T-shaped, and the four sliding bodies 320 are evenly distributed on the bottom cover 310. In this embodiment, the sliding body 320 includes a sliding rail 321.
[0060] In this embodiment, a plurality of the clamping members 400 are assembled on different sliding bodies 320 respectively. In this embodiment, the clamping member 400 includes a sliding block 410 and a clamping jaw 420. The sliding block 410 is provided with a concave groove 411, and the concave groove 411 cooperates with the sliding body 320 to realize The sliding block 410 slides on the sliding body 320. In this embodiment, the sliding block 410 is located on the sliding rail 321 of the sliding body 320. The clamping jaw 420 is fixedly mounted on the sliding block 410, so that when the sliding block 410 slides, the clamping jaw 420 also moves. In this embodiment, the clamping jaw 420 is cylindrical.
[0061] In this embodiment, the upper cover 350 covers the mounting seat (bottom cover 310) to form an inner cavity with the mounting seat, and the inner cavity is used to house the sliding body 320 and the linkage cable 130 , Limiting piece 140, etc. The upper cover 350 is provided with U-shaped holes 351. In this embodiment, the number of U-shaped holes 351 is four. The open end of the U-shaped holes 351 corresponds to the outer end of the upper cover 350. The claw 420 protrudes from the U-shaped hole 351. Therefore, in this embodiment, the sliding block 410 and the clamping jaw 420 are connected without the intermediate piece 230, thereby saving cost.
[0062] In order to prevent the piece to be clamped from directly abutting on the upper cover 350, in this embodiment, the clamping piece 400 further includes a gasket 440, the gasket 440 is circular, and the gasket 440 is fixed on On the clamping jaw 420, there is a certain distance between the washer 440 and the upper surface of the upper cover 350. The washer 440 is used to raise the part to be clamped to prevent the The upper surface of 350 touches to destroy the appearance of the upper surface of the clamping device.
[0063] In this embodiment, for a piece to be clamped of a specific size, after adjusting the position of the clamping piece 400, at this time, if the clamping device vibrates slightly, the clamping piece 400 is The position may change. Since all the clamping members 400 are linked by the linkage cable 130, the position of each clamping member 400 is changed, resulting in a poor clamping effect of the clamping device on the member to be clamped. To improve this problem, please see Figure 13 , Figure 15 In this embodiment, the clamping device further includes a positioning member 370 which is connected to at least one clamping member 400. In this embodiment, the number of the positioning member 370 is one. The positioning member 370 is connected to the sliding block 410 of a clamping member 400. When the clamping member 400 reaches a predetermined position, the positioning member 370 positions the clamping member 400 at this time to prevent the clamping member 400 Slide on the sliding body 320. Specifically, in this embodiment, the positioning member 370 is a thumb screw, the bottom cover 310 is provided with a strip-shaped opening 312, and the extending direction of the strip-shaped opening 312 is the same as that of the sliding body 320. The extension direction is the same, the thumb screw passes through the bar-shaped opening 312 of the mounting seat and is screwed to the slider 410. When the clamping member 400 reaches a predetermined position, the thumb screw is tightened at this time, That is, the nut part of the thumb screw abuts against the lower surface of the bottom cover 310, thereby preventing the slider 410 from continuing to slide; when sliding is required, only the thumb screw needs to be loosened at this time, and the clamping member 400 can slide on the sliding body 320. In this embodiment, the strip-shaped opening 312 can be used to limit the position where the clamping member 400 slides back and forth by a thumb screw.
