[0002] Cylinders, such as the spacers on rotors, are common components used in a wide range of mechanical devices. With the increasing number of large-scale mechanical devices, the outer diameter of cylinders has gradually increased, and the wall thickness of the cylinders has become relatively thin, resulting in a thin-walled cylinder structure. Thin-walled cylinders have low rigidity, and during machining, the cylinder wall thickness decreases as the machining device's jaws apply a preload to the cylinder. This makes the cylinder more susceptible to deformation under the existing preload, resulting in poor surface quality after machining. Utility Model Content

DETAILED DESCRIPTION

[0036] In order to better understand the above technical solution, the technical solution of the embodiment of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiment of the present application and the specific features in the embodiment are detailed descriptions of the technical solution of the embodiment of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiment of the present application and the technical features in the embodiment can be combined with each other.

[0037] The embodiment of the present application provides a cylinder clamping device 10, such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, the cylinder clamping device 10 includes: at least two sliders 100, a pressure plate 200, and a connecting assembly 300. A clamping space 110 is formed between the two sliders 100. The clamping space 110 is used to accommodate the cylinder 20. The pressure plate 200 is provided with a slide groove 210. The slide groove 210 extends along the radial direction of the cylinder 20. One end of the slider 100 cooperates with the slide groove 210, and the other end of the slider 100 is used to connect to the end of the cylinder 20. The slider 100 is arranged along the circumference of the cylinder 20. The connecting assembly 300 connects the sliders 100 located at both ends of the clamping space 110.

[0038] In this embodiment, the cylinder 20 is accommodated in a clamping space 110 formed between two sliders 100 , and the two sliders 100 are respectively located at two ends of the cylinder 20 . Figure 2 and Figure 10 The arrow at the X in the middle points to the radial direction of the cylinder 20. The slide groove 210 on the pressure plate 200 extends along the radial direction of the cylinder 20. One end of the slider 100 cooperates with the slide groove 210 and can slide along the slide groove 210, so that the slider 100 can approach or move away from the inner wall of the cylinder 20 along the radial direction of the cylinder 20, and the other end of the slider 100 abuts against the end of the cylinder 20.

[0039] For example, the chute 210 extends to the end surface of the pressure plate 200. The chute 210 is an I-shaped groove or a dovetail groove. The I-shaped groove or dovetail groove can lock the pressure plate 200 and the slider 100 in the vertical direction, thereby improving the stability of the connection between the pressure plate 200 and the slider 100. The end of the slider 100 can be connected to the cylinder 20 through a stop.

[0040] Multiple sliders 100 are provided at both ends of the cylinder 20. For example, the number of sliders 100 at each end can be three, four, or five. The sliders 100 are distributed circumferentially around the cylinder 20, enabling the sliders 100 to secure the ends of the cylinder 20 circumferentially. The sliders 100 at both ends of the clamping space 110 are positioned opposite each other and connected by a connecting assembly 300.

[0041] The present application avoids the need to clamp the circular sidewall of the cylinder 20. The sliders 100 at both ends of the cylinder 20 are connected by a connecting assembly 300, and a pre-tightening force is provided to the sliders 100 at both ends, so that the sliders 100 at both ends provide a clamping force on the cylinder 20. The ends of the cylinder 20 form a circumferential support through the sliders 100 and the pressure plate 200, thereby improving the structural strength and rigidity of the cylinder 20 during clamping, reducing the deformation of the cylinder 20, especially the thin-walled cylinder 20, during processing, and improving the processing quality of the cylinder 20. In addition, the sliders 100 can move radially along the cylinder 20 through the slide grooves 210 to extend to the end face position of the cylinder 20 and abut against cylinders 20 of different diameters, thereby enabling the cylinder clamping device 10 to clamp cylinders 20 of different sizes, thereby improving the adaptability and scope of use of the product.

[0042] In some embodiments provided in this application, Figure 2 、 Figure 10 、 Figure 15 、 Figure 16 and Figure 17As shown, optionally, there are multiple sliders 100, and the multiple sliders 100 are divided into multiple slider groups, each of which includes a first slider 120 and a second slider 130. The first slider 120 and the second slider 130 are respectively located at two ends of the clamping space 110 and can abut against the inner wall of the cylinder 20. There are two pressing plates 200, namely a first pressing plate 220 and a second pressing plate 230, which are respectively connected to the first slider 120 and the second slider 130. The cylinder clamping device 10 also includes a driving member 400. The driving member 400 is disposed in the slide groove 210 of the second pressing plate 230 and is used to drive the second slider 130 to move along the extension direction of the slide groove 210.

[0043] In this embodiment, multiple sliders 100 are divided into multiple slider groups, each slider group includes a first slider 120 and a second slider 130, the first slider 120 abuts against the top end of the inner wall of the cylinder 20, and the second slider 130 abuts against the bottom end of the inner wall of the cylinder 20, and the first slider 120 and the second slider 130 are connected by a connecting assembly 300.

[0044] The first pressing plate 220 is located at the top of the cylinder 20, and the chute 210 of the first pressing plate 220 is connected to the first slider 120. The second pressing plate 230 is located at the bottom of the cylinder 20, and the chute 210 of the second pressing plate 230 is connected to the second slider 130. A driving member 400 is provided in the chute 210 of the second pressing plate 230. The second slider 130 cooperates with the second pressing plate 230 via the driving member 400. The driving member 400 can drive the second slider 130 to move along the extension direction of the chute 210, that is, along the radial direction of the cylinder 20 toward or away from the inner wall of the cylinder 20, thereby enabling the first slider 120 and the second slider 130 to apply a preload force to the inner wall of the cylinder 20. The driving member 400 can adjust the pre-tightening force applied by the slider 100 to the cylinder 20, so that when the outer wall of the cylinder 20 is processed, the pre-tightening force of the tool can offset the pre-tightening force applied by the claws of the processing device, and reduce the deformation of the cylinder 20 caused by the cutting force of the tool, thereby improving the surface quality and processing accuracy of the cylinder 20.

[0045] For example, the processing device can be a lathe. When the outer diameter of the cylinder 20 is within a first threshold range, the second slider 130 is directly connected to the chute 210 of the second pressure plate 230. When the outer diameter of the cylinder 20 is within a second threshold range, the second slider 130 is connected to the chute 210 of the second pressure plate 230 via the driving member 400. The first threshold range is 400 mm to 600 mm, and the second threshold range is 600 mm to 800 mm.

[0046] In some embodiments provided in this application, Figure 15As shown, optionally, the driving member 400 includes a screw, and a contraction portion 410 is provided at both ends of the screw. The contraction portion 410 is rotatably connected to the slide groove 210 of the second pressure plate 230, and the outer periphery of the contraction portion 410 contracts along the radial direction of the screw.

[0047] In this embodiment, the driving member 400 may be a lead screw, which cooperates with the second slider 130 so that the driving member 400 can drive the second slider 130 to move by rotation. The axial direction of the lead screw is the same as the extension direction of the slide groove 210, and the shape of the slide groove 210 is adapted to the outer shape of the lead screw. The lead screw is rotatably connected to the slide groove 210 of the second pressure plate 230. It should be noted that because the upper end of the lead screw cooperates with the second slider 130, the pressure exerted by the lead screw on the lower slide groove 210 is reduced, allowing the lead screw to rotate smoothly within the slide groove 210 to drive the second slider 130. In addition, the contraction portions 410 at both ends of the lead screw contract inwardly along the radial direction of the lead screw, improving the smoothness of the lead screw's rotation within the slide groove 210.

[0048] For example, an operating portion is provided at the end of the driving member 400 , and an operator holds the operating portion with a tool to move the driving member 400 . The operating portion may be a hexagonal groove or an operating handle.

[0049] In another possible embodiment, the driving member 400 includes a gear, and the second slider 130 is provided with a rack. The gear and the rack cooperate with each other, so that the driving member 400 drives the second slider 130 to move.

[0050] In some embodiments provided in this application, Figure 2 、 Figure 5 、 Figure 6 and Figure 10 As shown, optionally, a long hole 140 is provided on the slider 100 , and the long hole 140 and the extending direction of the sliding groove 210 are the same, and the connecting component 300 passes through the long hole 140 .

[0051] In this embodiment, a long hole 140 is provided on the slider 100 along the radial direction of the cylinder 20, and the long hole 140 has the same extension direction as the slide groove 210. The connecting component 300 can change the position through the long hole 140, and then adjust the connection position with the sliders 100 at both ends along the radial direction of the cylinder 20. The connecting component 300 provides structural support for the appropriate position of the slider 100 according to the size of the cylinder 20, so that the cylinder clamping device 10 can clamp cylinders 20 of different sizes, thereby improving the adaptability and scope of use of the product.

[0052] In some embodiments provided in this application, Figure 10 and Figure 15As shown, optionally, a long hole 140 is provided on the first slider 120, and a plurality of adjustment holes 131 are provided on the second slider 130. The plurality of adjustment holes 131 are arranged at intervals along the extension direction of the long hole 140. One end of the connecting component 300 extends into the long hole 140, and the other end of the connecting component 300 cooperates with the adjustment hole 131.

[0053] In this embodiment, the long hole 140 is provided on the first slider 120, and the distribution direction of the multiple adjustment holes 131 on the second slider 130 is the same as the extension direction of the long hole 140. The two ends of the connecting component 300 respectively cooperate with the long hole 140 and the adjustment hole 131. Specifically, the upper end of the connecting component 300 can adjust the connection position with the first slider 120 through the long hole 140, and the lower end of the connecting component 300 can adjust the connection position with the second slider 130 through the adjustment hole 131, so that the connecting component 300 can adjust the connection position with the first slider 120 and the second slider 130 respectively along the radial direction of the cylinder 20, and then provide structural support for the appropriate position of the slider 100 according to the size of the cylinder 20, so that the cylinder clamping device 10 can clamp cylinders 20 of different sizes, thereby improving the adaptability and usage range of the product.

[0054] Exemplarily, both ends of the connecting assembly 300 are provided with threads, the adjustment hole 131 is a threaded hole, and the upper end of the connecting assembly 300 is connected to the first slider 120 through a nut.

[0055] In some embodiments provided in this application, Figure 3 As shown, optionally, the pressing plate 200 includes: a supporting portion 240 and a plurality of connecting portions 250 , wherein the plurality of connecting portions 250 are respectively connected to the supporting portion 240 along the circumferential direction, and the sliding groove 210 is provided in the connecting portion 250 .

[0056] In this embodiment, the support portion 240 is located in the middle of the pressure plate 200, and multiple connecting portions 250 are evenly distributed on the periphery of the support portion 240. The slider 100 cooperates with the slide groove 210 on the connecting portion 250, and the pressure plate 200 forms an outward-diverging shape, which ensures the structural strength of the pressure plate 200 while reducing the material used for the pressure plate 200 and saving the cost of the cylinder clamping device 10.

[0057] Exemplarily, the number of the connecting portions 250 is the same as the number of the sliders 100 at either end, and the connection positions between the supporting portions 240 and the connecting portions 250 are provided with rounded corners to reduce stress at the connection positions.

[0058] In some embodiments provided in this application, Figure 2 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 14As shown, optionally, the connecting assembly 300 includes: a first connecting rod 310 and a second connecting rod 320, the first connecting rod 310 connects the support parts 240 located at both ends of the clamping space 110, and the second connecting rod 320 connects the sliders 100 located at both ends of the clamping space 110.

[0059] In this embodiment, the support parts 240 on the first pressure plate 220 and the second pressure plate 230 are respectively connected to the first connecting rod 310, so that the first connecting rod 310 is connected to the middle position of the pressure plate 200. The first connecting rod 310 locks the center position, thereby improving the stability of the clamping.

[0060] The first slider 120 and the second slider 130 are respectively connected to the second connecting rod 320. Through the first connecting rod 310 and the second connecting rod 320, the pressure plate 200 and the slider 100 are connected, thereby improving the structural strength of the cylinder clamping device 10 in the middle and outer edge positions, thereby improving the force uniformity and stability when the cylinder 20 is clamped.

[0061] For example, the outer diameter of the first connecting rod 310 is greater than the outer diameter of the second connecting rod 320. The first connecting rod 310 and the second connecting rod 320 are both screws, and both ends of the first connecting member are connected to the support portion 240 via nuts. The outer diameter of the screw of the first connecting rod 310 can be M48, and the outer diameter of the screw of the second connecting rod 320 can be M12.

[0062] For example, Figure 11 In the figure, L1 is the length of the first connecting rod 310, Figure 13 In the figure, L2 is the length of the first connecting rod 310. The length of the first connecting rod 310 is greater than the length of the second connecting rod 320, that is, L1 is greater than L2. The lengths of the first connecting rod 310 and the second connecting rod 320 are divided into multiple groups based on the length of the cylinder 20. This facilitates the cylinder clamping device 10 to clamp cylinders 20 of different heights, thereby improving the adaptability and range of use of the product. Specifically, the first connecting rod 310 and the second connecting rod 320 are divided into three groups based on length, with L1 being 550mm, 650mm, and 750mm, respectively, and L2 being 385mm, 485mm, and 585mm, respectively. The corresponding cylinder 20 lengths are 250mm to 350mm, 350mm to 450mm, and 450mm to 550mm, respectively.

[0063] In some embodiments provided in this application, Figure 2 、 Figure 10 and Figure 17 As shown, optionally, the cylinder clamping device 10 further includes a support plate 500, which is connected to the end of the first connecting rod 310, and the support plate 500 extends radially from the first connecting rod 310, and the support plate 500 is used to connect to the processing device.

[0064] In this embodiment, a support plate 500 is provided at the lower end of the first connecting rod 310, and the support plate 500 extends outward radially along the first connecting rod 310. After the bottom end of the first connecting rod 310 passes through the processing device, the support plate 500 at the bottom can be engaged with the processing device through a stopper, thereby improving the stability of the bottom of the cylinder clamping device 10 and preventing the cylinder clamping device 10 from tipping over.

[0065] In some embodiments provided in this application, Figure 11 、 Figure 12 、 Figure 13 and Figure 14 As shown, optionally, the connection assembly 300 further includes a polygonal column 330 , which is connected to the ends of the first connection rod 310 and / or the second connection rod 320 .

[0066] In this embodiment, a polygonal column 330 is provided at the end of the first connecting rod 310 and / or the second connecting rod 320, and the cross-section of the polygonal column 330 is polygonal. When the connecting assembly 300 is connected to the pressure plate 200 or the slider 100, the first connecting rod 310 and / or the second connecting rod 320 can be fixed during assembly by clamping the polygonal column 330, thereby preventing the first connecting rod 310 and / or the second connecting rod 320 from rotating, thereby improving the convenience of assembly.

[0067] Exemplarily, the polygonal column 330 may be a square structure. Figure 11 and Figure 13 , P is the length of the polygonal column 330 , and P may be 20 mm to 25 mm.

[0068] In some embodiments provided in this application, Figure 2 、 Figure 10 and Figure 17 As shown, optionally, the cylinder clamping device 10 also includes an adjusting member 600 and / or a lifting eye screw 700, one end of the adjusting member 600 extends into the bottom of the pressure plate 200 and can adjust the insertion depth, the other end of the adjusting member 600 is used to connect with the processing device, and the lifting eye screw 700 is arranged at the end of the connecting assembly 300.

[0069] In this embodiment, a mating hole is provided at the bottom of the pressure plate 200. One end of the adjusting member 600 is mated with the mating hole. The adjusting member 600 can adjust the depth of insertion into the mating hole. The other end of the adjusting member 600 can abut against the processing device. After clamping, the cylinder 20 becomes one with the cylinder clamping device 10. When the cylinder 20 is aligned by dialing, the adjusting member 600 adjusts the support height of the pressure plate 200, thereby adjusting the position of the cylinder 20 and aligning the cylinder 20. This improves the alignment speed and the overall rigidity of the cylinder 20. This avoids the deformation of the cylinder 20 caused by the use of a jack on the cylinder 20 in the related art.

[0070] Exemplarily, there are multiple adjusting members 600 , and the multiple adjusting members 600 are evenly distributed along the circumference of the second pressing plate 230 .

[0071] For example, the matching hole can be a threaded hole, and the adjusting member 600 can be a stud. Alternatively, the matching hole and the adjusting member 600 can be interference-fitted, and the adjusting member 600 can be provided with a knocking plate, and the insertion depth of the adjusting member 600 can be adjusted by knocking the knocking plate.

[0072] An eye screw 700 is provided at the end of the connecting assembly 300. Specifically, the eye screw 700 is connected to the polygonal column 330 of the first connecting rod 310, so as to facilitate lifting and moving the clamped cylinder 20.

[0073] In a specific embodiment, a special tooling for a spacer lathe (i.e., a cylinder clamping device 10) meets the processing requirements of the spacer (i.e., the cylinder 20). Solution 1 is designed for a spacer outer diameter of 400mm to 600mm, and uses upper and lower pressing of the spacer to improve rigidity and meet the cutting force requirements during processing. Solution 2 is designed for a spacer outer diameter of 600mm to 800mm. The large outer diameter of the spacer leads to poor rigidity itself, so in Solution 2, in addition to using upper and lower pressing of the spacer to improve rigidity, a pre-tightening force is applied from the inside to the outside to improve rigidity. The tooling is split into multiple independent modules and flexibly assembled to achieve multifunctional purposes. The tooling is serialized according to the outer diameter and height of the spacer, which can realize the universality of the tooling and meet the clamping requirements of the spacer during the processing.

[0074] The slider 100 slides within the T-slot of the pressure plate 200. The slider's position relative to the pressure plate 200 is adjusted based on the outer diameter of the spacer, enabling compression of spacers with outer diameters ranging from 400mm to 600mm. The T-slot structure allows for both left-right adjustment and vertical locking of the tooling.

[0075] The spacer is clamped using a fixture, which locks the center and tail ends of the fixture's pressure plate 200. Attaching the fixture to the spacer improves its overall rigidity. The spacer, along with the fixture, is then mounted on the lathe table and clamped using the machine's jaws. This fixture enhances the spacer's rigidity, preventing deformation caused by the jaws. It also further offsets deformation caused by the tool's cutting forces during machining, improving the spacer's surface quality and machining accuracy.

[0076] First, place the locking screw (i.e., the driving member 400) into the slide groove 210 of the second pressure plate 230, and then place the second slider 130 into the slide groove 210 opening of the second pressure plate 230, and drive the second slider 130 to be embedded in the second pressure plate 230 by rotating the screw. When the spacer is assembled with the tooling, the rotating screw can allow the second slider 130 to apply a pre-tightening force to the inner wall of the spacer. The locking screw and the locking slider 100 apply a pre-tightening force to the inner wall of the spacer. As the outer diameter of the spacer is larger, the rigidity of the spacer decreases more as the wall thickness decreases when machining the outer circle, resulting in poor roundness and surface quality of the outer circle of the spacer. Since the spacer can adjust the tightening force applied by the second slider 130 during tooling, the pre-tightening force applied by the machine jaws is offset by the tooling during the outer circle machining of the spacer, and at the same time, the deformation of the spacer caused by the cutting force of the lathe tool can be reduced, thereby improving the surface quality and machining accuracy of the spacer.

[0077] A jack is typically used to align workpieces on a lathe. However, since the spacer is a thin-walled component, using a jack to press against it during alignment can cause deformation. In this design, the spacer is clamped in a fixture, integrating the two components. During alignment, the spacer is aligned by fine-tuning the alignment screw (i.e., adjustment element 600).
