[0028] Embodiment 1

[0029] Refer to Figures 1 to 5, A clamping structure, including a support part, a pressing part, and a positioning part. The support part includes at least two support bodies 1. The support body 1 has a support end face 11. The support body 1 extends integrally in the up and down direction, and the support end face 11 is the upper end face of the support body 1. With two support bodies 1, the support part can effectively support the parts by means of the areas of the support end faces 11 of the two support bodies 1. To achieve a better support effect, in this embodiment, each clamping structure is provided with three support bodies 1 to achieve three-point positioning support. The pressing part includes at least one pressing body 2. In this embodiment, the pressing body 2 is a rod extending in the left and right directions, specifically a stainless steel rod. Then, the pressing bodies 2 in multiple clamping structures can share a common rod. The slight movement of a rod can simultaneously drive multiple parts to move to a predetermined installation position. The pressing part includes two pressing bodies 2. The distances from the two pressing bodies 2 to the support part have a first difference, which is shown as H in Figure 5 The first difference enables the pressing part to generate a component force in the up and down direction and the horizontal direction on the parts. When the pressing part presses down, it can push the parts into place in the up and down direction and the horizontal direction, and effectively clamp the parts, preventing the parts from shifting in the horizontal direction and preventing the micro-vibrations caused by cleaning, etc., from causing the parts to shift. A first storage gap is formed between the pressing body 2 and the support end face 11, that is, there is a space in the up and down direction. The positioning part includes at least two positioning bodies 3. The positioning body 3 has a positioning side face 31. A second storage gap is formed between the positioning side faces 31. The second storage gap and the first storage gap form a storage space for placing the parts. In this embodiment, the positioning body 3 is integrally cylindrical and extends in the up and down direction, and the positioning side face 31 is the opposite side faces of the two positioning bodies 3 in the left and right directions. To better clamp large parts, two positioning bodies 3 can be arranged on the left and right sides of the storage space respectively. In addition, the distance between the positioning side faces 31 can be set to gradually increase along the direction from the support part to the pressing part, that is, the positioning side face 31 is an inclined surface. This inclined surface can be formed by machining or by setting the axis line of the positioning body 3 to be inclined, so as to better guide the parts to be installed in place in the up and down direction.

[0030] A connecting body 4 is provided between the pressing bodies 2. The two ends of the connecting body 4 are respectively fixedly connected to the two pressing bodies 2. The connecting body 4 can be fixedly connected to the two pressing bodies 2 by welding, and its welding seams are protected by forming a passivation layer through pickling. The setting of the connecting body 4 can effectively prevent the two pressing bodies 2 from being pushed apart and deformed when the two pressing bodies 2 receive the horizontal reaction force from the parts, avoid the effective height of the pressing bodies 2 in the up and down direction from decreasing, and ensure the pressing function of the pressing bodies 2.

[0031] Both the support body 1 and the positioning body 3 include a column body 12 and a protective sleeve 13 sleeved on the end of the column body 12. When cleaning parts, such as by jet cleaning, it usually causes the parts to vibrate. Then, the protective sleeve 13 at the end of the column body 12 can effectively prevent the parts from vibrating and being bruised by collision. The column body 12 is threadedly connected to the protective sleeve 13 and / or the protective sleeve 13 is made of PTFE material. When the parts are overly pressed, the position of the protective sleeve 13 can be adjusted by threaded connection to be appropriately loosened, or the protective sleeve 13 made of PTFE material can provide buffering, or both loosening and buffering can be achieved simultaneously to better protect the surface quality of the parts. When the parts are insufficiently pressed, the position of the protective sleeve 13 can also be adjusted by threaded connection to be appropriately tightened, or the elastic-plasticity of the protective sleeve 13 made of PTFE material can provide a pressing force. In addition, the protective sleeve 13 made of PTFE material can also effectively prevent corrosion by substances such as cleaning liquid, improving the service life of the clamping structure and the clamping device.

[0032] A clamping device includes the above clamping structure, including a first clamping layer 5 and a second clamping layer 6, and the first clamping layer 5 is detachably connected to the second clamping layer 6. In this embodiment, the clamping device includes three clamping bodies arranged in sequence along a predetermined direction. Any two adjacent clamping bodies are respectively set as the first clamping layer 5 and the second clamping layer 6. Among them, the middle clamping body serves as both the first clamping layer 5 of the upper clamping body and the clamping layer 6 of the lower clamping body, effectively improving the space utilization rate of the device and providing good installation convenience. An installation structure is provided between the first clamping layer 5 and the second clamping layer 6. The installation structure includes a first installation end face 51 provided on the first clamping layer 5 and a first installation side face 52 provided on the first clamping layer 5. The installation structure also includes a second installation end face 62 provided on the second clamping layer 6 and a second installation side face 61 provided on the second clamping layer 6. The first installation end face 51 abuts against the second installation end face 62, and the first installation side face 52 abuts against the second installation side face 61. The first clamping layer 5 is set as a first frame 53, and the second clamping layer 6 is set as a second frame 63. The second frame 63 includes a first frame body 631 and a second frame body 632. The second installation side face 61 is provided on the outside of the first frame body 631, and the second installation end face 62 is provided on the end face of the second frame body 632. The second installation side face 61 and the second installation end face 62 form a stepped surface. Among them, the first frame body 631 and the second frame body 632 are both stainless steel bars in this embodiment. Therefore, the second installation end face 62 and the second installation side face 61 are arc surfaces. The second frame 63 further includes a frame bar 634, and the frame bar 634 is fixedly connected to the first frame body 631 and / or the second frame body 632. The pressing body 2 is provided on the frame body. At least two support bodies 1 are both provided on the first clamping layer 5, at least one pressing body 2 is both provided on the second clamping layer 6, and at least two positioning bodies 3 are provided on the first clamping layer 5 and / or the second clamping layer 6.

[0033] As described above, it is only the preferred embodiment of the present invention, and there is no restriction in any form on the present invention. Therefore, any modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
