A clip 100 according to an embodiment of the present invention is described below with reference to fig. 1 and 2.

The clamp 100 according to the first embodiment of the present invention is used for clamping a material 500, an outer contour surface of the material 500 is cylindrical, and the clamp 100 includes a bearing portion 110, a pressing portion 120 and a driving portion.

The bearing part 110 includes a first body 111 and at least two bearing wheels 112, the bearing wheels 112 are connected to the first body 111, and a space is formed between two adjacent bearing wheels 112. The pressing part 120 includes a second body 121 and a pressing wheel 122, the pressing wheel 122 is connected to the second body 121, and the axle direction of the pressing wheel 122 is the same as the axle direction of the bearing wheel 112. The driving part comprises a first driving piece 131, an output end of the first driving piece 131 is fixed on the second body 121, and the first driving piece 131 is used for enabling the pressing wheel 122 to clamp the material 500 between the pressing wheel 122 and the bearing wheel 112.

In practical use, the material 500 with a cylindrical outer contour is first placed on at least two of the bearing wheels 112, and at this time, the curved side of the material 500 contacts with the bearing wheels 112, so that the material 500 receives radial support force from the bearing wheels 112. Then, the first driving element 131 starts to operate, and drives the second body 121 to move towards the direction of the bearing wheel 112, and finally the pressing wheel 122 on the second body 121 presses the side of the material 500 away from the bearing wheel 112, and at this time, the pressing wheel 122 also applies a radial force to the material 500. It can be understood that the clamping operation of the material 500 is completed under the combined action of the bearing wheels 112 and the pressing wheels 122.

When the material needs to be unloaded, the first driving member 131 drives the second body 121 to move in a direction away from the first body 111, and then the material 500 is unloaded from the bearing wheel 112.

Specifically, as shown in fig. 1 and fig. 2, the bearing portion 110 includes a first body 111 and at least two bearing wheels 112, the bearing wheels 112 are cylindrical and are connected to the first body 111 through fasteners or in a manner of being fastened by a fastening slot, at this time, the bearing wheels 112 can rotate around a fixed axis relative to the first body 111 or cannot move relative to the first body 111, and a spacing distance is provided between two adjacent bearing wheels 112. The carrier wheel 112 may be functionally divided into two types of limit wheels 113 and auxiliary wheels (not shown), wherein two limit wheels 113 are disposed at the same height of the first body 111. The limiting wheels 113 are used for bearing the pressure caused by the gravity of the material 500 and applying a radial acting force to the material 500, and it can be understood that the distance between the two limiting wheels 113 determines the diameter of the material 500 which can be clamped by the clamp 100, that is, the clamp 100 can be used for clamping only when the diameter of the material 500 is larger than the distance between the two adjacent bearing wheels 112 and when the material 500 is placed on the bearing wheels 112, the lower end of the material 500 does not touch the first main body 111.

For the convenience of distinction, the two limiting wheels 113 are hereinafter named as a first limiting wheel 113 and a second limiting wheel 113.

The auxiliary wheel is arranged between the first limiting wheel 113 and the second limiting wheel 113, so that the lower end of the material 500 is prevented from contacting with the first main body 111 due to the fact that the material 500 with the diameter being too small is placed; or the first limiting wheel 113 and the second limiting wheel 113 are arranged on the side of the first limiting wheel 113 far away from the second limiting wheel 113 and the side of the second limiting wheel 113 far away from the first limiting wheel 113, so as to limit the maximum diameter of the material 500 which can be clamped by the clamp 100.

The pressing portion 120 includes a second body 121 and at least one pressing wheel 122, the pressing wheel 122 is also cylindrical and is connected to the second body 121 through a fastener or a slot fastener, and at this time, the pressing wheel 122 may rotate around a fixed axis relative to the second body 121 or may not move relative to the second body 121. The driving part includes a first driving member 131, the first driving member 131 may be an air cylinder or a hydraulic cylinder, etc., and an output end of the first driving member 131 is fixed on the second body 121 and can drive the second body 121 to approach or separate from the first body 111. It can be understood that, when the material 500 needs to be clamped, the first driving member 131 drives the second body 121 to move toward the first body 111, and the pressing wheel 122 presses the material 500; when the material needs to be unloaded, the first driving member 131 drives the second body 121 to move in a direction away from the first body 111.

The number of the pinch rollers 122 determines the direction of the force applied by the pinch rollers 122 to the material 500, and the axle of the pinch rollers 122 is parallel to the axle of each of the load bearing wheels 112. When the material 500 is clamped, if the number of the pressing wheels 122 is one, a connecting line between the pressing wheel 122 and the first limiting wheel 113 and the second limiting wheel 113 is in an isosceles triangle shape; if the number of the pinch rollers 122 is even, the pinch rollers 122 arranged on one side of the limit wheel 113 and the pinch rollers 122 arranged on the second side of the limit wheel 113 are symmetrically distributed; if the number of the pressing wheels 122 is an odd number greater than one, a connecting line between one pressing wheel 122 and the first and second limiting wheels 113 and 113 is in an isosceles triangle shape, and the distribution mode of the remaining pressing wheels 122 is the same as that of the even pressing wheels 122, which is not described herein again. It can be understood that the material 500 placed on the bearing wheel 112 will always be subjected to the radial force of at least one pressing wheel 122, and if the number of the pressing wheels 122 is greater than two, the number of the pressing wheels 122 applying the radial force to the material 500 will vary according to the diameter of the material 500. The design is such that when the pressing wheel 122 exerts a radial force on the material 500, the forces exerted on the material 500 by the pressing wheel 122 and the bearing wheel 112 can be balanced, so that the material 500 cannot move under the clamping of the pressing wheel 122 and the bearing wheel 112.

Through the design, the diameter of the material 500 is only larger than the interval between two adjacent bearing wheels 112, and when the material 500 is placed on the bearing wheels 112, the lower end of the material 500 does not touch the first main body 111, so that the clamp 100 can be applied to the material 500 with any size in the range, and the cost is effectively reduced.

It should be understood that the first body 111 and the first driving member 131 can be fixed to the same support frame at the same time, that is, when the carrying portion 110 moves, the pressing portion 120 also moves at the same time; or the second body 121 is fixed to a support frame that does not move, and the first body 111 is fixed to another moving device, so that the carrying part 110 can move relative to the pressing part 120. The latter design enables the same compression part 120 to be adapted to a plurality of load bearing parts 110.

In some embodiments of the present invention, the bearing wheel 112 can rotate with respect to the first body 111, the pressing wheel 122 can rotate with respect to the second body 121, the driving portion further includes a second driving member 132, the bearing wheel 112 includes a driving wheel 114, an output end of the second driving member 132 is fixed to the driving wheel 114, and the second driving member 132 is configured to enable the driving wheel 114 to drive the material 500 to rotate.

Specifically, as shown in fig. 1, the axle of the carrying wheel 112 is connected to the first body 111 through a bearing, and when the carrying wheel 112 is subjected to a tangential force, the carrying wheel rotates relative to the first body 111. Accordingly, the axle of the pressure wheel 122 is connected to the second body 121 through a bearing, and when the pressure wheel 122 is subjected to a tangential force, the pressure wheel rotates relative to the second body 121.

At least one of the two limit wheels 113 of the carrier wheel 112 is a driving wheel 114. The driving portion further includes a second driving member 132, and the second driving member 132 may be a dc brushless motor, or a dc brush motor, and can convert electric energy into rotational kinetic energy of the driving wheel 114. The driving wheel 114 is driven by the second driving member 132 to rotate in a fixed axis.

When the material 500 is clamped between the pressing wheel 122 and the carrying wheel 112, a larger static friction force exists between the driving wheel 114 and the curved side surface of the material 500, so that the driving wheel 114 is rotated by the second driving member 132, and the driving wheel 114 drives the material 500 to move. It will be appreciated that because the radial forces experienced by the material 500 from the pinch roller 122 and the load wheel 112 balance each other, the material 500 cannot translate but rather only rotate about its central axis.

It can be understood that, when the fixture 100 is used in a laser cleaning device, a high-pressure water gun jet cleaning device, or the like, and there is a device whose moving range is limited to operate on the material 500, the material 500 can rotate by itself, so that the limited device can complete the operation on the side of the material 500 facing the device.

In some embodiments of the present invention, the carrying wheels 112 are detachably coupled to the first body 111, and the distance between the carrying wheels 112 is adjustable.

Specifically, a plurality of positioning holes are disposed on the first body 111 along the direction in which the limiting wheels 113 are disposed, and the positioning holes are symmetrically disposed on both sides of the first body 111, that is, the positioning holes are disposed opposite to each other. The bearing wheel 112 is used for bearing the pressure caused by the gravity of the material 500 and applying a radial acting force to the material 500, the axle of the limiting wheel 113 passes through a pair of oppositely arranged positioning holes, two ends of the axle of the limiting wheel 113 are respectively tapped, and the bearing wheel 112 can be positioned at the positioning holes by a positioning nut matched with the axle.

When the diameter of the first limiting wheel 113 is smaller than the distance between the second limiting wheel 113 and the first limiting wheel 113, the axle of the first limiting wheel 113 and the positioning hole into which the axle of the second limiting wheel 113 is inserted can be changed to change the positions of the first limiting wheel 113 and the second limiting wheel 113 connected to the first main body 111, so that the purpose of reducing the distance between the first limiting wheel 113 and the second limiting wheel 113 is achieved. It will be appreciated that such a design further extends the range of applicability of the clamp 100.

In some embodiments of the present invention, the adjusting portion 140 is further included, the adjusting portion 140 includes a first adjusting member 141 and a second adjusting member 142, the driving portion further includes a third driving member 133 and a fourth driving member 134, an output end of the third driving member 133 is fixed to the first adjusting member 141, the third driving member 133 is configured to enable the first adjusting member 141 to approach or separate from the material 500, an output end of the fourth driving member 134 is fixed to the second adjusting member 142, the fourth driving member 134 is configured to enable the second adjusting member 142 to approach or separate from the material 500, and the first adjusting member 141 and the second adjusting member 142 are configured to adjust a degree of an included angle between the material 500 and the carrier wheel 112.

In the actual use process, firstly, the material 500 is placed on the bearing wheel 112, and then the first aligning member 141 moves towards the direction of the material 500 under the action of the third driving member 133 and abuts against the material 500; at the same time, or later, the second aligning member 142 moves toward the material 500 under the action of the fourth driving member 134, and also abuts against the material 500. At this time, the central axis of the material 500 is parallel to the axle of the bearing wheel 112 and the axle of the pressing wheel 122 under the combined action of the first aligning member 141 and the second aligning member 142. It should be understood that the parallel relationship here refers to a positional relationship that satisfies the requirement of parallelism between the central axis of the material 500 and the axles of the bearing wheels 112 and the axles of the pressing wheels 122 when the material 500 is clamped.

After the material 500 is compressed between the pinch roller 122 and the carrier roller 112 by the pinch roller 122, the third driving element 133 drives the first aligning member 141 to return to the initial position, and the fourth driving element 134 drives the second aligning member 142 to return to the initial position, so as to avoid interference on subsequent processes.

Specifically, as shown in fig. 1 and fig. 2, the first aligning member 141 and the second aligning member 142 are both plate-shaped, the first aligning member 141 abuts against a plane on the material 500, and the first aligning member 141 and the second aligning member 142 abut against a plane on the material 500, and are parallel to each other when abutting against the material 500, and widths and lengths of the first aligning member 141 and the second aligning member 142 can be correspondingly adjusted according to actual requirements, so that the first aligning member 141 and the second aligning member 142 can adjust an angle between the material 500 and a wheel axle of the carrier wheel 112.

The third driving member 133 and the fourth driving member 134 may be linear cylinders, hydraulic cylinders, etc., or swing cylinders, swing hydraulic cylinders, etc. Under the action of the third driving element 133 and the fourth driving element 134, when the first aligning element 141 and the second aligning element 142 abut against the material 500, acting forces in opposite directions can be applied to the material 500, so that the first aligning element 141 and the second aligning element 142 can complete the adjustment of the material 500. It can be understood that, by such a design, when the material 500 is pressed on the bearing wheel 112 by the pressing wheel 122, the radial acting force applied to the material 500 by the pressing wheel 122 can pass through the center of gravity of the material 500, or the moment between the center of gravity and the radial acting force is small, thereby effectively avoiding accidents in the pressing process of the pressing wheel 122 caused by the inclined placement of the material 500.

In some embodiments of the present invention, the third driving member 133 is used for making the first aligning member 141 move linearly, and the fourth driving member 134 is used for making the second aligning member 142 rotate.

Specifically, as shown in fig. 2, the third driving element 133 may be a linear cylinder, a linear hydraulic cylinder, or a crank and rocker structure driven by a motor, and the like, and can drive the first aligning member 141 to make a linear motion toward the material 500, and during the moving process of the first aligning member 141, the side of the first aligning member 141 facing the material 500 is always perpendicular to the axle of the carrier wheel 112. The fourth driving member 134 may be a swing cylinder, a swing hydraulic cylinder, or a motor-driven rotating shaft structure, and at this time, a rotating shaft is inevitably provided in the fourth driving member 134, and the output end of the fourth driving member 134 performs a circular motion around the rotating shaft, so that the second aligning member 142 can perform a circular motion around the rotating shaft of the fourth driving member 134 under the driving of the fourth driving member 134.

It can be understood that, the fourth driving component 134 cannot make the second adjusting component 142 apply a large acting force to the material 500 due to the laborious leverage, so that the second adjusting component 142 plays a role in limiting the position during the process of adjusting the inclination angle of the material 500; the first aligning member 141 opposite to the first aligning member can apply a large acting force to the material 500 under the driving of the third driving member 133, so as to cooperate with the second aligning member 142 to complete the aligning task of the material 500. Under such a design, the fourth driving element 134 does not need to occupy too much lateral space, and can be matched with the third driving element 133 to achieve the purpose of the first adjusting element 141 and the second adjusting element 142, thereby effectively saving the space occupied by the clamp 100.

A laser cleaning apparatus according to an embodiment of the present invention is described below with reference to fig. 3 and 4.

The laser cleaning device according to the second aspect embodiment of the present invention comprises a laser device 200 and the fixture 100 according to the above first aspect embodiment of the present invention, the laser device 200 comprises a bracket 210 and a laser head 220, the laser head 220 is connected to the bracket 210, and the laser head 220 is used for emitting laser to the material 500 between the pressing wheels 122 and the bearing wheels 112.

Specifically, the laser device comprises a support 210 and a laser head 220, the laser head 220 is connected to the support 210, and when the laser device works, the laser head 220 emits laser towards the material 500, and the material 500 is cleaned through the laser. In the process, the laser head 220 can deflect at a certain angle, so that the cleaning of different positions of the material 500 is completed, the laser head 220 can not deflect, and the displacement of the laser head 220 is realized by moving the shaft, so that the cleaning of different positions of the material 500 is completed.

Further, as shown in fig. 3, the laser head 220 is mounted on a three-axis moving structure 211, the three-axis moving structure 211 is fixed on the bracket 210 by a slot fastener, or a fastener, and the laser head 220 can move along the X-axis, Y-axis and Z-axis directions by the three-axis moving structure 211. In practical use, when the material 500 is clamped on the fixture 100, the laser head 220 is driven by the three-axis moving structure 211 to move in the direction of the material 500 along the X-axis direction, and when the distance between the laser head 220 and the material 500 is the preset cleaning distance, the laser head 220 starts to emit laser.

At this time, if the driving wheel 114 is arranged in the bearing wheel 112, the material 500 can synchronously rotate under the driving of the driving wheel 114, and in the process, the laser head 220 only needs to move along the Y axis or the Z axis after the material 500 rotates for one circle; if the bearing wheel 112 only plays a supporting role and cannot drive the material 500 to rotate, the laser head 220 is driven by the three-axis moving structure 211 to move uninterruptedly along the Y axis and the Z axis until the side surface of the material 500 is cleaned.

By adopting the clamp 100, the laser cleaning equipment can perform laser cleaning on materials 500 with more sizes, and the cleaning cost is effectively reduced.

In some embodiments of the present invention, the laser head further includes a light shielding portion 300, the light shielding portion 300 includes a light shielding main body 310, a receiving cavity 311 is disposed in the light shielding main body 310, a bearing wheel 112 and a pressing wheel 122 are disposed in the receiving cavity 311, a cleaning hole 312 is disposed on the light shielding main body 310, the cleaning hole 312 is communicated with the receiving cavity 311, and the cleaning hole 312 is used for enabling the laser head 220 to be inserted into the receiving cavity 311.

Specifically, as shown in fig. 3 and 4, the light shielding portion 300 includes a light shielding main body 310, the light shielding main body 310 is a box structure formed by welding sheet metal parts, a space inside the light shielding main body 310 is an accommodating cavity 311, and the fixture 100 holding the material 500 to be cleaned is placed inside the accommodating cavity. The side of the light shielding main body 310 facing the laser device 200 is provided with a through hole communicated with the accommodating cavity 311, the through hole is a cleaning hole 312, and the shape and size of the cleaning hole 312 only need to meet the requirement that the laser head 220 and a rod fixed with the laser head 220 can be inserted into the accommodating cavity 311.

During the in-service use, the staff through setting up the door on shading main part 310, with material 500 clamping in the anchor clamps 100 in holding chamber 311, or the anchor clamps 100 that the centre gripping has material 500, under drive structure's drive, the door department through automatic opening and shutting enters into holding chamber 311, realizes treating the replacement of cleaning material 500.
