Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe production technology, specifically to a corrugated pipe positioning structure for a corrugated pipe cutting device. Background Technology

[0002] A bellows is a tubular elastic sensing element made of foldable corrugated sheets connected along the folding and stretching direction. Bellows are widely used in instrumentation, primarily as measuring elements in pressure gauges, converting pressure into displacement or force. Bellows have thin walls and high sensitivity, with a measurement range from tens of Pascals to tens of megapascals. However, bellows require precise positioning during cutting to prevent displacement, which could lead to product quality issues.

[0003] Chinese Utility Model Patent Publication No. CN215549111U discloses a corrugated pipe production positioning and cutting device. The specification of this device reveals that a clamping assembly is provided on a support base. Rotating the cylinder moves the arc-shaped clamping plate downwards, making it easier to clamp the corrugated pipe. An arc-shaped rubber is provided on the arc-shaped support plate to prevent rotation of the corrugated pipe during cutting, thus improving the practicality of the device. However, this device lacks a multi-directional limiting structure, making it prone to displacement of the corrugated pipe during cutting. Furthermore, it lacks an adjustment structure, making it difficult to adjust the distance between the moving and fixed positioning assemblies according to the length of the corrugated pipe, resulting in poor overall practicality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a corrugated pipe positioning structure for a corrugated pipe cutting device. It can effectively solve the problems in the prior art, which are that the existing technology does not have a multi-directional limiting structure, which makes it easy for the corrugated pipe to shift during the cutting process, and it does not have an adjustment structure, which makes it inconvenient to adjust the distance between the moving positioning component and the fixed positioning component according to the length of the corrugated pipe, resulting in poor overall practicality.

[0005] The technical solution adopted by this utility model is: a corrugated pipe positioning structure for a corrugated pipe cutting device, including a conveying frame and a moving positioning component. A fixing plate two is fixedly installed on the inner edge of the conveying frame. A transmission motor and a slide table are fixedly installed on the end of the fixing plate two away from the conveying frame. A slider two is slidably connected to the end of the slide table away from the fixing plate two. A fixing positioning component is fixedly installed on the end of the slider two away from the slide table. A fixing positioning component is fixedly installed on the inner edge of the conveying frame. The mobile positioning component includes a positioning plate and a fixing frame. A vertical limiting cylinder and a guide sleeve are fixedly installed at the end of the fixing frame away from the positioning plate. A limiting strip is fixedly installed on the output end of the vertical limiting cylinder. A limiting groove is formed through one end of the limiting strip. The fixed positioning component includes a positioning plate 2 and a fixing frame 2. A vertical limiting cylinder 2 is fixedly installed at the end of the fixing frame 2 away from the positioning plate 2. A limiting strip 2 is fixedly installed at the output end of the vertical limiting cylinder 2. A limiting groove 2 is formed through one end of the limiting strip 2.

[0006] Preferably, a guide post is fixedly installed at the end of the limiting strip away from the positioning plate, and the guide post and the guide sleeve are slidably connected.

[0007] With the above technical solution, when the vertical limiting cylinder pushes the limiting strip to move up and down, the guide post can slide inside the guide sleeve, which can play a limiting role. During the cutting and moving process, the limiting strip is displaced, which affects the product quality.

[0008] Preferably, a guide frame is fixedly installed at the end of the fixed frame away from the positioning plate, and an adjusting plate is slidably connected to the inner edge of the guide frame. A connecting plate and a slider three are fixedly installed at the end of the positioning plate away from the fixed frame, and the slider three and the slider two are fixedly installed.

[0009] Through the above technical solution, the drive motor drives the slide table, which in turn moves the slider and the fixed moving positioning component as a whole. The distance between the moving positioning component and the fixed positioning component can be adjusted according to the length of the corrugated pipe, which can easily adapt to corrugated pipes of various lengths without replacing the positioning structure, thus improving the versatility of the overall positioning structure.

[0010] Preferably, a guide post 2 is fixedly installed at one end of the limiting strip 2 near the vertical limiting cylinder 2, and a guide sleeve 2 is fixedly installed at one end of the fixing frame 2 away from the positioning plate 2, and the guide post 2 and the guide sleeve 2 are slidably connected.

[0011] Through the above technical solution, the guide post 2 slides along the guide sleeve 2 to provide vertical guidance for the limit strip 2 driven by the vertical limit cylinder 2. In coordination with the guide structure of the moving positioning component, the two ends of the corrugated pipe to be cut can be positioned in the same way.

[0012] Preferably, both the first limiting groove and the second limiting groove have a semi-circular cross-section, and both the first limiting groove and the second limiting groove are provided in multiple identical portions and are distributed at equal intervals. The first limiting strip and the second limiting strip are provided in two identical portions and have the same structure.

[0013] The above technical solution increases the contact area by matching the curvature of the semi-circular groove with the outer circle of the corrugated pipe, which can reduce the deformation of the corrugated pipe caused by local pressure. In addition, multiple sets of equally spaced limiting grooves can be used to accommodate corrugated pipes of different diameters, thereby improving their processing efficiency.

[0014] Preferably, a protective frame is fixedly installed at one end of the conveyor frame near the fixed positioning component. Both ends of the protective frame are provided with through slots. A fixing plate is fixedly installed at the end of the protective frame away from the conveyor frame. A flip cover is rotatably installed at the end of the fixing plate away from the conveyor frame. A transparent plate is fixedly installed at the end of the flip cover away from the conveyor frame.

[0015] The above technical solution uses a protective frame to block metal shavings from flying during cutting, preventing injury. The through-slot is only large enough for a corrugated pipe to pass through, facilitating loading and unloading. The flip cover can be opened by flipping it over, and the internal positioning status can be observed through a transparent plate when closed.

[0016] Preferably, a mounting bracket is fixedly installed at one end of the fixed positioning component near the conveyor frame, a side limiting cylinder is fixedly installed on both the moving positioning component and the fixed positioning component, a limiting plate is fixedly installed at the output end of the side limiting cylinder, and a side baffle is fixedly installed at the other end of the moving positioning component and the fixed positioning component away from the limiting plate.

[0017] The above technical solution uses a side-limiting cylinder to push the limiting plate towards the side baffle, thereby clamping the corrugated pipe laterally. Through multi-dimensional positioning, displacement during corrugated pipe cutting can be avoided, ensuring the perpendicularity and dimensional accuracy of the cutting port.

[0018] Compared with the prior art, the present invention provides a corrugated pipe positioning structure for a corrugated pipe cutting device, which has the following advantages: 1. The corrugated pipe cutting device uses a corrugated pipe positioning structure. The drive motor drives the slide table, which in turn moves the slider and the fixed moving positioning component as a whole. The distance between the moving positioning component and the fixed positioning component can be adjusted according to the length of the corrugated pipe. It can easily adapt to corrugated pipes of various lengths and specifications without the need to replace the positioning structure, thus improving the versatility of the overall positioning structure. 2. The corrugated pipe cutting device uses a corrugated pipe positioning structure. By matching the arc of the semi-circular groove with the outer circle of the corrugated pipe, the contact area is increased, which can reduce the deformation of the corrugated pipe caused by local pressure. In addition, multiple sets of equally spaced limiting grooves can correspond to corrugated pipes of different diameters, improving their processing efficiency. Furthermore, the side limiting cylinder pushes the limiting plate to move towards the side baffle, clamping the corrugated pipe laterally. Through multi-dimensional positioning, displacement during corrugated pipe cutting can be avoided. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: As Figure 1-8As shown, the present invention provides a corrugated pipe positioning structure for a corrugated pipe cutting device, including a conveying frame 1 and a moving positioning component 11. A fixing plate 2 7 is fixedly installed on the inner edge of the conveying frame 1. A drive motor 8 and a slide table 9 are fixedly installed on the end of the fixing plate 2 7 away from the conveying frame 1. A slider 2 10 is slidably connected to the end of the slide table 9 away from the fixing plate 2 7. A fixing positioning component 15 is fixedly installed on the end of the slider 2 10 away from the slide table 9. The fixing positioning component 15 is fixedly installed on the inner edge of the conveying frame 1. The mobile positioning component 11 includes a positioning plate 1101 and a fixing frame 1104. A vertical limiting cylinder 1105 and a guide sleeve 1109 are fixedly installed at one end of the fixing frame 1104 away from the positioning plate 1101. A limiting strip 1106 is fixedly installed on the output end of the vertical limiting cylinder 1105. A limiting groove 1107 is opened through one end of the limiting strip 1106. The fixed positioning component 15 includes a positioning plate 2 1501 and a fixing frame 2 1502. A vertical limiting cylinder 2 1504 is fixedly installed at one end of the fixing frame 2 1502 away from the positioning plate 2 1501. A limiting strip 2 1505 is fixedly installed at the output end of the vertical limiting cylinder 2 1504. A limiting groove 2 1506 is opened through one end of the limiting strip 2 1505.

[0023] Specifically, a guide post 1108 is fixedly installed at the end of the limiting strip 1106 away from the positioning plate 1101. The guide post 1108 and the guide sleeve 1109 are slidably connected. The advantage is that when the limiting strip 1106 is pushed up and down by the vertical limiting cylinder 1105, the guide post 1108 can slide inside the guide sleeve 1109, which can play a limiting role. During the cutting and moving process, the limiting strip 1106 will be displaced, thus affecting the product quality.

[0024] Specifically, a guide frame 1110 is fixedly installed at the end of the fixed frame 1104 away from the positioning plate 1101. An adjusting plate 1111 is slidably connected to the inner edge of the guide frame 1110. A connecting plate 1102 and a slider 1103 are fixedly installed at the end of the positioning plate 1101 away from the fixed frame 1104. The slider 1103 and the slider 10 are fixedly installed. The advantage is that the drive motor 8 drives the slide table 9, which drives the slider 10 and the fixed moving positioning component 11 to move as a whole. The distance between the moving positioning component 11 and the fixed positioning component 15 can be adjusted according to the length of the corrugated pipe. It can be easily adapted to corrugated pipes of various lengths and specifications. There is no need to replace the positioning structure, which can improve the versatility of the overall positioning structure.

[0025] Specifically, a guide post 1503 is fixedly installed at one end of the limiting strip 1505 near the vertical limiting cylinder 1504, and a guide sleeve 1507 is fixedly installed at the end of the fixing frame 1502 away from the positioning plate 1501. The guide post 1503 and the guide sleeve 1507 are slidably connected. The advantage is that by sliding the guide post 1503 along the guide sleeve 1507, the limiting strip 1505 driven by the vertical limiting cylinder 1504 is provided with vertical guidance. In coordination with the guide structure of the moving positioning component 11, the two ends of the corrugated pipe to be cut can be positioned in the same way.

[0026] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0027] Specifically, both the first limiting groove 1107 and the second limiting groove 1506 have a semi-circular cross-section. There are multiple identical limiting grooves 1107 and 1506, and they are evenly spaced. There are two identical limiting strips 1106 and 1505, and they have the same structure. The advantage is that by matching the curvature of the semi-circular groove with the outer circle of the corrugated pipe, the contact area is increased, which can reduce the deformation of the corrugated pipe caused by local pressure. In addition, multiple sets of equally spaced limiting grooves can correspond to corrugated pipes of different diameters, thereby improving the processing efficiency.

[0028] Specifically, a protective frame 2 is fixedly installed at one end of the conveyor frame 1 near the fixed positioning component 15. Both ends of the protective frame 2 are provided with through slots 3. A fixing plate 4 is fixedly installed at the end of the protective frame 2 away from the conveyor frame 1. A flip cover 5 is rotatably installed at the end of the fixing plate 4 away from the conveyor frame 1. A transparent plate 6 is fixedly installed at the end of the flip cover 5 away from the conveyor frame 1. The advantage is that the protective frame 2 blocks the splashing of metal chips generated during cutting, avoiding injury. The through slot 3 is only sized to allow the corrugated pipe to pass through, which facilitates loading and unloading. The flip cover 5 can be flipped open, and the internal positioning status can be observed through the transparent plate 6 when closed.

[0029] Specifically, a mounting bracket 12 is fixedly installed at one end of the fixed positioning component 15 near the conveyor frame 1. Side limiting cylinders 13 are fixedly installed on both the moving positioning component 11 and the fixed positioning component 15. A limiting plate 14 is fixedly installed at the output end of the side limiting cylinder 13. A side baffle 16 is fixedly installed at the other end of the moving positioning component 11 and the fixed positioning component 15 away from the limiting plate 14. The advantage is that by pushing the limiting plate 14 towards the side baffle 16 through the side limiting cylinder 13, the corrugated pipe is clamped laterally. Through multi-dimensional positioning, displacement during corrugated pipe cutting can be avoided, ensuring the perpendicularity and dimensional accuracy of the cutting port.

[0030] Working Principle: During use, when the vertical limiting cylinder 1105 pushes the limiting strip 1106 up and down, the guide post 1108 slides within the guide sleeve 1109, thus providing a limiting function. During the cutting and moving process, the limiting strip 1106 may shift, affecting product quality. The drive motor 8 drives the slide table 9, which in turn moves the slider 10 and the fixed moving positioning component 11 as a whole. The distance between the moving positioning component 11 and the fixed positioning component 15 can be adjusted according to the length of the corrugated pipe, making it easy to adapt to corrugated pipes of various lengths without requiring replacement of the positioning structure, thus improving the versatility of the overall positioning structure. The guide post 1503 slides along the guide sleeve 1507, providing a guide for the limiting strip 1505 driven by the vertical limiting cylinder 1504. Vertical guidance, in coordination with the guiding structure of the moving positioning component 11, ensures that both ends of the corrugated pipe to be cut are positioned consistently. By matching the arc of the semi-circular groove with the outer circle of the corrugated pipe, the contact area is increased, which can reduce the deformation of the corrugated pipe caused by local pressure. In addition, multiple sets of equally spaced limiting grooves can correspond to corrugated pipes of different diameters, improving their processing efficiency. The protective frame 2 blocks the splashing of metal chips generated during cutting, preventing injury. The through groove 3 is sized to allow only the corrugated pipe to pass through, which facilitates loading and unloading. The flip cover 5 can be flipped open, and when closed, the internal positioning status can be observed through the transparent plate 6. The side limiting cylinder 13 pushes the limiting plate 14 to move towards the side baffle 16, clamping the corrugated pipe laterally. Through multi-dimensional positioning, displacement of the corrugated pipe during cutting can be avoided, ensuring the verticality and dimensional accuracy of the cutting end.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
