Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0029] Embodiment 1

A second clamping cylinder 12 is rotatably connected to one side of the second vertical plate 10. Both ends of the output ends of the first clamping cylinder 3 and the second clamping cylinder 12 are fixedly connected with sliding clamping plates 11. One end of the sliding clamping plate 11 is movably connected with a clamping block 13. A mounting component 9 is arranged inside the sliding clamping plate 11 at one end of the clamping block 13.

[0031] The adjusting assembly 2 includes an adjusting groove 201 which is opened on one side inside the connecting frame 1. One side of the back surface of the connecting frame 1 is movably connected with an adjusting knob 205. One end of the adjusting knob 205 is fixedly connected with an adjusting bolt 206 extending into the adjusting groove 201. An adjusting plate 202 is movably connected inside the adjusting groove 201. On both sides of the back surface of the adjusting plate 202, bolt holes 203 which are threadedly matched with the adjusting bolt 206 are equidistantly opened. By rotating the adjusting knob 205, the adjusting plate 202 is slid to a proper position inside the adjusting groove 201, and then the adjusting bolt 206 is threadedly engaged with the proper bolt hole 203 to realize the limit fixation after the sliding of the connecting frame 1, thereby the overall length between the first clamping cylinder 3 and the second clamping cylinder 12 can be changed to meet the processing of products with different lengths.

[0032] In this embodiment, a sliding structure is formed between the adjusting plate 202 and the inside of the adjusting groove 201, and the shapes of the side views of the adjusting groove 201 and the adjusting plate 202 are in the shape of a Chinese character 'gong'.

[0035] On the basis of Embodiment 1, a preferred embodiment of the cylinder clamping and rotating mechanism provided by the present utility model is as Figures 1 to 5 shown: The mounting assembly 9 includes a fixing groove 906 which is opened on both sides inside the sliding clamping plate 11. Clamping grooves 902 are opened at both ends of the sliding clamping plate 11 on one side of the limiting block 905. A positioning frame 908 extending into the clamping grooves 902 is movably connected inside the fixing groove 906. One side of the positioning frame 908 is fixedly connected with a sliding rod 909 extending outside the sliding clamping plate 11. One end of the sliding rod 909 is fixedly connected with a sliding frame 903. A return spring 907 is wound around the surface of the sliding rod 909 on one side of the positioning frame 908. One end of the return spring 907 is fixedly connected with the inner wall of the fixing groove 906. One side of the clamping block 13 is fixedly connected with a clamping plate 901. Positioning holes 910 are opened at the upper and lower ends on one side of the clamping plate 901. By using the sliding clamping engagement of the clamping plate 901 inside the clamping grooves 902 and the elastic force of the return spring 907, the positioning frame 908 is slid and clamped into the positioning holes 910, thereby the disassembly and replacement actions between the clamping block 13 and the sliding clamping plate 11 can be realized.

[0036] In this embodiment, a clamping structure is formed between the inside of the clamping plate 901 and the clamping groove 902, and the shapes of the top views of the clamping plate 901 and the clamping groove 902 are convex. By using the sliding engagement between the convex clamping plate 901 and the inside of the clamping groove 902, the firm stability of the initial clamping and installation between the clamping block 13 and the sliding clamping plate 11 is improved.

[0037] In this embodiment, a limiting groove 904 is provided on the inner wall of the fixing groove 906, and limiting blocks 905 that are slidably engaged with the inside of the limiting groove 904 are fixedly connected to both ends of the positioning frame 908. By using the sliding of the limiting blocks 905 inside the limiting groove 904, the back-and-forth sliding of the positioning frame 908 becomes more stable.

[0038] In this embodiment, a clamping structure is formed between one side of the positioning frame 908 and the inside of the positioning hole 910, and the shape of the side view of the positioning frame 908 is C-shaped. By using the clamping between the C-shaped positioning frame 908 and the inside of the positioning hole 910, the limiting and locking between the clamping plate 901 and the inside of the clamping groove 902 are realized.

[0039] Furthermore, strengthening blocks 6 are fixedly connected to both ends of one side of the top of the bottom plate 7, and one side of each strengthening block 6 is fixedly connected to the lower ends of one side of the first vertical plate 4 and the second vertical plate 10 respectively. By using the L-shaped strengthening blocks 6, the firm stability of the installation between the bottom plate 7 and the first vertical plate 4 and the second vertical plate 10 can be improved.

[0040] Furthermore, through grooves 8 are provided on both sides of the top of the bottom plate 7, and the through grooves 8 are distributed in a triangular shape on the top of the bottom plate 7. By using the triangularly distributed through grooves 8, it is convenient to install and fix the bottom plate 7 at a suitable position through external bolts.

[0041] In addition, anti-slip lines 14 are provided on one side of the clamping block 13, and the cross-sectional shape of the anti-slip lines 14 is wavy. By using the wavy anti-slip lines 14, the clamping friction between the clamping block 13 and the product is increased, thereby improving the clamping stability of the product.

[0042] The working principle and usage process of the present utility model: First, adjust the distance between the first clamping cylinder 3 and the second clamping cylinder 12 according to products of different lengths. At this time, by rotating the adjustment knob 205, using the arc-shaped anti-slip protrusions 204, the contact friction between the user's finger and the adjustment knob 205 is increased, so that the adjustment bolt 206 rotates more smoothly until it completely disengages from the inside of the bolt hole 203. Then, pull the connecting frame 1 so that the adjustment plate 202 slides inside the adjustment groove 201 to a suitable position, and then rotate the adjustment knob 205 in the reverse direction so that the adjustment bolt 206 is screwed into a suitable bolt hole 203, realizing the limiting fixation after the sliding of the connecting frame 1. Furthermore, the overall length between the first clamping cylinder 3 and the second clamping cylinder 12 can be changed, enabling it to meet the processing of products of different lengths and improving its applicability;

[0043] Afterwards, the bottom plate 7 is installed and fixed in place through external bolts and the through groove 8. Then, the product is placed between the sliding clamping plates 11. After that, the first clamping cylinder 3 and the second clamping cylinder 12 work to drive the sliding clamping plates 11 to move towards the product, and the wavy anti-slip lines 14 are used to increase the frictional force between the clamping block 13 and the product, thereby realizing the clamping and fixing of the product by the clamping block 13. At the same time, the rotary cylinder 5 can be started to make the first clamping cylinder 3 rotate, and thus the product can be rotated to realize the clamping and rotating processing action;

[0044] Meanwhile, when the clamping block 13 is worn or damaged, or different-shaped clamping blocks 13 are selected for cylindrical or other-shaped products, the sliding frame 903 can be pulled to drive the sliding rod 909 to slide, so that the positioning frame 908 slides and compresses the return spring 907 until it completely disengages from the inside of the positioning hole 910. Then, the clamping block 13 is pushed forcefully to make the clamping plate 901 completely slide out of the inside of the clamping groove 902, realizing the disassembly of the clamping block 13. When installing the clamping block 13, first pull the sliding frame 903 to drive the positioning frame 908 to slide into the inside of the fixing groove 906. Then, slide the clamping plate 901 into the inside of the clamping groove 902. Then, release the sliding frame 903. Using the elastic force of the return spring 907, the positioning frame 908 slides into the inside of the positioning hole 910, realizing the sliding engagement between the clamping plate 901 and the inside of the clamping groove 902, and thus the disassembly and replacement action between the clamping block 13 and the sliding clamping plate 11 can be realized.

[0045] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
