Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, specifically to a positioning and cutting device for gray cast iron production. Background Technology

[0002] Gray cast iron, with its excellent casting performance, shock absorption, wear resistance, and cost advantages, is widely used in machinery manufacturing, construction engineering, pipe fittings, and many other fields, and is one of the most widely used cast iron materials in industrial production. After gray cast iron is used to produce pipes or plates, it needs to be cut and processed according to requirements to produce fixed lengths. Traditional cutting devices often have fixed clamping distances or limited adjustment ranges, making it difficult to flexibly adapt to gray cast iron workpieces of different widths (such as plates, profiles, and casting blanks). Although some handheld portable devices are flexible in operation and can adapt to different work scenarios, they rely on manual control of the movement trajectory during the cutting process, which can easily lead to uneven cutting surfaces and excessive dimensional deviations due to operational vibrations. Fixed workbench-type devices have better cutting stability, but their movement is limited, making it impossible to meet the cutting needs of irregular workpieces or special positions. Moreover, the movement of the cutting unit mostly relies on the sliding of guide rails, and debris entering the rails causes wear, affecting the service life. Summary of the Invention

[0013] Preferably, the tightening screw is screwed onto the clamp to engage with the teeth of the second toothed seat, ensuring the clamp is properly engaged.

[0014] The positioning and cutting device for gray cast iron production proposed in this invention has the following advantages:

[0015] 1. This device uses a first motor in the main structure to drive the first gear to mesh with the first gear seat, thereby achieving flexible adjustment of the clamping distance. This allows for precise fitting of gray cast iron workpieces (such as plates, profiles, and casting blanks) and worktables of different widths and specifications. Combined with the modular series design of the third gear seat in the adjustable distance structure (extended by combining docking blocks and interfaces), the cutting range adjustment boundary is further expanded. At the same time, the device has both handheld and table-fixed operation modes, which can meet diverse needs such as batch cutting of regular workpieces, irregular workpiece cutting, and fixed-point cutting in special locations. This solves the pain points of limited movement of traditional fixed devices and poor adaptability of handheld devices.

[0016] 2. The locking unit uses a camera to capture the position of the first toothed seat teeth in real time, and in conjunction with the electric push rod, precisely adjusts the positioning of the first pressure plate. Then, the first hydraulic cylinder powerfully locks the plate, ensuring that the main structure does not shift after being clamped. The second motor drives the second gear to cooperate with the interlocking second toothed seat, and the T-shaped second slide groove guides and limits the slide, making the movement trajectory of the cutting machine body smooth and avoiding uneven cutting surfaces and dimensional deviations caused by manual operation. The distance adjustment structure uses a third motor to drive the third gear, which enables precise quantitative adjustment of the cutting range. Combined with the limiting function of the clamp, it can achieve equidistant and fixed-length cutting, greatly improving the consistency of product dimensions.

[0017] 3. The main structure enhances clamping stability through the concave design of the clamp and the synergy of the tightening screw. Combined with the bidirectional force locking of the locking unit, it ensures that there is no loosening or deviation during the cutting process. At the same time, the device does not have a complex electrical or hydraulic system, so there are fewer points of failure. Moreover, the modular assembly of each component allows it to operate stably in harsh environments such as industrial dust and vibration, which significantly reduces the failure rate and downtime maintenance costs.

[0018] 4. The overall structure of the device is simple, and the symmetrical arrangement of the handles facilitates force application and control during handheld operation. The drive logic of each motor and hydraulic cylinder is clear, and no professional or complicated training is required to get started. The cutting unit, the distance adjustment structure, and the locking unit are all independent modular components, which are easy to disassemble and assemble. Damaged parts can be replaced specifically during subsequent maintenance without overall overhaul, which greatly reduces maintenance difficulty and parts costs. In addition, the staggered fit design of the second gear seat ensures continuous gear meshing when the cutting unit moves, without the need for additional calibration, further improving operational flexibility and work efficiency.

[0019] 4. The third toothed seat of the adjustable spacing structure is fixed in series with bolts, and the number of units can be flexibly increased or decreased according to the cutting range requirements. The applicable scenarios can be expanded without replacing the whole equipment. The device is suitable for batch production in small processing plants, and can also meet the temporary cutting needs of large-scale engineering sites. Its versatility far exceeds that of traditional single-function cutting equipment. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-9 This invention provides a technical solution: a positioning and cutting device for gray cast iron production, comprising a main structure 1, a locking unit 2, a cutting unit 3, and an adjusting structure 4; the locking unit 2 is fixedly mounted on the main structure 1, the cutting unit 3 is movably mounted on the main structure 1, and the adjusting structure 4 is fixedly mounted on the main structure 1; the main structure 1 is used for clamping and limiting, and the main structure 1 can be used for hand-held construction or clamping a workbench; the locking unit 2 is used for positioning the main structure 1 after it fits different widths; the cutting unit 3 is used for moving and cutting; and the adjusting structure 4 is used to adjust the cutting range.

[0032] As a preferred embodiment, the main structure 1 further includes a first clamping seat 11, a first gear seat 12, a second clamping seat 13, a first motor 14, a first gear 15, a pair of second gear seats 16, a pair of handrails 17, a pair of clamping brackets 18, and several tightening screws 19; the first clamping seat 11 is concave, and both ends of the first clamping seat 11 have first sliding grooves 51 on opposite sidewalls; the rear sidewall of the first clamping seat 11 has a T-shaped second sliding groove 52; the front sidewall of the first clamping seat 11 has a third sliding groove 53; the left end of the first clamping seat 11 has a through mounting opening 61, and the right side of the mounting opening 61 has a locking slot; the first gear seat 12 is movably inserted into the first... The first sliding groove 51 is located within the clamp 11, and the first gear seat 12 can move along the first clamp 11. A meshing opening 62 is provided on the right side of the first gear seat 12 near its rear end. Several teeth are provided on the upper wall of the first gear seat 12. The second clamp 13 is fixedly located at the left end of the first clamp 11 and corresponds to the first clamp 11. The rear side wall of the second clamp 13 has a second sliding groove 52 identical to the rear side wall of the first clamp 11. The first motor 14 is fixedly located within the mounting opening 61. The first gear 15 is fixedly located on the drive end of the first motor 14 and meshes with the first gear seat 12. One of the second gear seats 16... Fixedly mounted on the upper wall of the first clamp 11 and near the rear end, one end of the other second toothed seat 16 is fixedly mounted on the upper wall of the second clamp 13. The pair of second toothed seats 16 are staggered and relatively close together. When the first toothed seat 12 moves, the teeth of the second toothed seats 16 always remain opposite, for the cutting unit 3 to move along the second toothed seats 16. A pair of handles 17 are symmetrically arranged on the front side wall of the first clamp 11. One end of a pair of clamps 18 is symmetrically arranged on the right side wall of the first clamp 11 and the left side wall of the second clamp 13, respectively, and the clamps 18 correspond to the mating openings 62 of the first toothed seats 12. The other ends of the pair of clamps 18 are both relatively concave structures. Several top The tightening screw 19 is movably screwed onto the upper wall and side wall of the other end of the clamp 18, and is installed through the clamp. The first motor 14 drives the first gear 15 to rotate, causing the first gear 15 to mesh with the first gear seat 12, and causing the first gear seat 12 to move on the first clamp 11, thereby adjusting the distance between the second clamp 13 and the clamp 18 on the first clamp 11. It can be used to fix it on the table or on the plate. The distance between the clamps 18 is adjusted by the first motor 14 driving the first gear seat 12 to move within the first clamp 11, so as to fit and clamp different widths. The tightening screw 19 is screwed onto the clamp 18 to fit the teeth of the second gear seat 16 to ensure the clamp 18 is locked.

[0033] More specifically, the main structure 1 is the core foundation for the device to achieve clamping and limiting and adapt to multiple scenarios. The first motor 14 is fixed in the mounting port 61, and the drive end is connected to the first gear 15. The first gear 15 meshes with the first gear seat 12 that is movably inserted in the first slide groove 51. By driving the first gear 15 to rotate through the first motor 14, the first gear seat 12 can be driven to move along the first clamping seat 11, thereby adjusting the distance between the pair of clamping frames 18 on the first clamping seat 11 and the second clamping seat 13, so as to achieve fitting clamping of workpieces or tables of different widths. With the clamping frame 18 and the tightening screw 19, the device can switch between two modes: handheld construction and fixed use with clamping table.

[0034] As a preferred embodiment, the locking unit 2 further includes a force-bearing frame 21, a connecting rod 22, an electric push rod 23, a first hydraulic cylinder 24, a first pressure plate 25, and a pair of cameras 26. One end of the force-bearing frame 21 is movably inserted into the third sliding groove 53, and the other end of the force-bearing frame 21 is attached to the upper wall of the first clamping seat 11. The locking port passes through the middle of the force-bearing frame 21. The other end of the connecting rod 22 is fixedly connected to the other end of the force-bearing frame 21. The electric push rod 23 is fixedly installed on the upper left wall of the first clamping seat 11, and the telescopic end of the electric push rod 23 is opposite to the locking port. The telescopic end of the electric push rod 23 is fixedly connected to the other end of the connecting rod 22. One end of the first hydraulic cylinder 24 is fixedly installed in the middle of the force-bearing frame 21. The first hydraulic cylinder 24 is located inside the lock, and the first pressure plate 25 is fixedly installed on the first hydraulic cylinder 24. The first pressure plate 25 can fit with the first tooth seat 12. A pair of cameras 26 are symmetrically arranged on the lower walls of the left and right sides of the first pressure plate 25, and the cameras 26 are opposite to the first tooth seat 12. The force frame 21 is connected to the third slide groove 53 to realize the reverse force of the first hydraulic cylinder 24 to keep it stable. Thus, the first pressure plate 25 is driven down by the first hydraulic cylinder 24 to apply force to limit and lock the first tooth seat 12. The lower wall of the first pressure plate 25 can be provided with a single tooth, so that the camera 26 can be used to determine the position and adjust the extension and retraction of the electric push rod 23 to fit with the tooth of the first tooth seat 12.

[0035] More specifically, the locking unit 2 is the core component that ensures the accuracy and stability of the clamping and positioning of the main structure 1. One end of the force-bearing frame 21 is movably inserted into the third slide groove 53 of the first clamping seat 11, and the other end is attached to the upper wall of the first clamping seat 11 with a locking port through the middle. It provides a stable mounting carrier for the first hydraulic cylinder 24 and achieves reverse force application through cooperation with the third slide groove 53, ensuring the structural stability of the locking process. One end of the adapter rod 22 is fixedly connected to the force-bearing frame 21, and the other end is connected to the telescopic end of the electric push rod 23, forming a power transmission bridge. A pair of cameras 26 Symmetrically positioned on the lower walls of the left and right sides of the first pressure plate 25, opposite to the first tooth seat 12, the electric push rod 23 is fixed to the upper left wall of the first clamp 11. Its telescopic end drives the force-bearing frame 21 to move along the third slide groove 53 through the adapter rod 22, thereby adjusting the corresponding position of the first pressure plate 25 and the first tooth seat 12, ensuring precise alignment of the locking parts. With the position locking of the electric push rod 23, a strong limiting and locking of the first tooth seat 12 is achieved, preventing the main structure 1 from shifting during the cutting process.

[0036] As a preferred embodiment, the cutting unit 3 further includes a slide 31, a cutting machine body 32, a second motor 33, and a second gear 34. One end of the slide 31 is movably inserted into the second slide groove 52, and the slide 31 is located behind the first clamping seat 11. The slide 31 can pass through the second slide groove 52 of the second clamping seat 13. The cutting machine body 32 is fixedly mounted on the right end of the slide 31. The second motor 33 is fixedly mounted on the upper wall of the slide 31 and close to the cutting machine body 32. The second gear 34 is fixedly mounted on the driving end of the second motor 33. The second gear 34 can mesh with the staggered second gear seats 16 respectively. The second motor 33 drives the second gear 34 to rotate, causing the second gear 34 to mesh with the second gear seats 16. The slide 31 moves within the second slide groove 52 of the first clamping seat 11, and the slide 31 can enter the second slide groove 52 of the second clamping seat 13, thereby realizing moving and cutting along the first clamping seat 11 and the second clamping seat 13.

[0037] More specifically, the cutting unit 3 is the core execution component for achieving stable moving cutting of gray cast iron plates. Through the coordinated design of guidance, power, and execution, it ensures that the cutting process is smooth, accurate, and without jamming. One end of the slide 31 is movably inserted into the T-shaped second slide groove 52 on the rear side of the first clamp 11, and can pass through the same second slide groove 52 on the second clamp 13 to form a continuous and stable moving track, providing precise guidance for the translation of the cutting machine body 32 and avoiding deviation during the movement; at the same time, the slide 31 serves as a load-bearing carrier, providing stable installation support for the cutting machine body 32 and the second motor 33.

[0038] As a preferred embodiment, the adjustable structure 4 further includes a support frame 41, a third motor 42, a third gear 43, a third gear seat 44, a second hydraulic cylinder 45, a second pressure plate 46, and a clamping bracket 47. The support frame 41 is fixedly installed in the middle of the upper wall of the first clamping seat 11. A telescopic opening 63 is provided in the middle of the other end of the support frame 41. The third motor 42 is fixedly installed in the telescopic opening 63. The third gear 43 is fixedly installed on the drive end of the third motor 42. The third gear seat 44 movably passes through the telescopic opening 63, and teeth are equidistantly arranged on the lower wall of the third gear seat 44. The third gear seat 44 meshes with the third gear 43. A mating interface 7 is symmetrically arranged on the left side wall of the third gear seat 44, and a mating block 8 that fits with the mating interface 7 is provided on the right side wall of the third gear seat 44. The three-tooth seat 44 can be inserted into the interface 7 through the docking block 8 and fixed in series with bolts. The second hydraulic cylinder 45 is fixedly set in the middle of the side wall of the support frame 41, and the extension end of the second hydraulic cylinder 45 is opposite to the third tooth seat 44. The second pressure plate 46 is fixedly set on the extension end of the second hydraulic cylinder 45, and the second pressure plate 46 is in contact with the third tooth seat 44. The card holder 47 is a door frame structure, and the middle part of the card holder 47 is engaged with the left end of the third tooth seat 44. The middle part of the card holder 47 is detachably placed on the engaging block at the right end of the third tooth seat 44. The third motor 42 drives the third gear 43 to rotate, and the third gear 43 transmits power to the third tooth seat 44, so that the third tooth seat 44 is subjected to force and moves in the limited state of the support frame 41, thereby adjusting the position of the card holder 47 to control the cutting distance.

[0039] More specifically, the adjustable length structure 4 is the core component for achieving precise control of the cutting range and range expansion. The support frame 41 is fixed to the middle of the upper wall of the first clamp 11, and the other end of the support frame 41 is provided with a telescopic opening 63, which provides a stable installation space for the third motor 42 and a limit guide for the translation of the third gear seat 44, ensuring structural stability during the adjustable length process and avoiding deviation. The third motor 42 is fixed inside the telescopic opening 63, and the drive end is connected to the third gear 43, which meshes with the third gear seat 44 that moves through the telescopic opening 63. The third motor 42 drives the third gear 43 to rotate, transmitting power to the third gear seat 44, causing the third gear seat 44 to move smoothly under the limiting action of the support frame 41, thereby driving the clamp 47 to move synchronously and achieving precise control of the cutting length.

[0040] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0041] First, the device drives the first motor 14 in the main structure 1, which drives the first gear 15 to rotate. The first gear 15 passes through the mounting port 61 and meshes with the first gear seat 12, which in turn drives the first gear seat 12 to move along the first slide groove 51 of the first clamping seat 11. This adjusts the distance between the clamping bracket 18 on the left side wall of the second clamping seat 13 and the clamping bracket 18 on the right side wall of the first clamping seat 11, thereby adjusting the clamping distance of the main structure 1. This allows it to be used to clamp and fix tabletops of different widths, or to clamp and fix them to the board with the help of the handrail 17.

[0042] Then, the first hydraulic cylinder 24 in the locking unit 2 is activated. The first hydraulic cylinder 24 drives the first pressure plate 25 to descend and fit against the first tooth seat 12 for downward pressure and limit. If the lower wall of the first pressure plate 25 is provided with a single tooth, it can be judged and corrected by the image of the camera 26, and extended and retracted by the first electric push rod 23, thereby driving the force frame 21 to move along the third slide groove 53 through the adapter rod 22, adjusting the position of the first pressure plate 25 to promote tooth correction.

[0043] Since the other end of the clamp 18 is concave, after the table is clamped by the other end of the clamp 18, the clamping and positioning are assisted by the tightening screw 19 according to actual needs, so that the teeth of the second tooth seat 16 on the second clamp 13 and the second tooth seat 16 on the first clamp 11 can always remain opposite.

[0044] Then, the third motor 42 located in the telescopic opening 63 of the adjusting structure 4 is started, driving the third gear 43 to rotate. Through the meshing transmission between the third gear 43 and the third tooth seat 44, the third tooth seat 44 is driven to move along the telescopic opening 63 of the support frame 41, thereby adjusting the side stop distance of the clamp 47, that is, adjusting the cutting width; and through the second hydraulic cylinder 45, the second pressure plate 46 is raised to press against the third tooth seat 44 and lock it in place.

[0045] The plate is passed through the clamps 47, and the cut end of the plate passes through the cutting unit 3 and is attached to the upper limit of the clamps 47. The second motor 33 in the cutting unit 3 can then be started. The second motor 33 drives the second gear 34 to rotate. With the rotation of the second gear 34 and its meshing with the second gear seat 16, and the movable installation of the slide 31 in the second slide groove 52, the slide 31 is moved along the second slide groove 52 by force, thereby realizing the movement of the cutting machine body 32. The slide 31 can enter the second slide groove 52 of the second clamp 13 from the second slide groove 52 of the first clamp 11 and dock, realizing a large range of movement of the cutting machine body 32 for cutting.

[0046] The equipment can also be used for cutting by hand holding the handle 17, or by using the concave clamp at the other end of the clamp 18 to hold pipes of a certain size for cutting. With the help of the shielding of the clamp 47, equidistant cutting can be achieved.

[0047] The main body 32 of the cutting machine can be selected according to actual needs, and the applicable cutting range can be set according to the actual processing requirements. The lengths of the first clamp 11, the first toothed seat 12, and the second toothed seat 16 can be adjusted. The range of the cutting width can also be extended by connecting the interface 7 on the side wall of the third toothed seat 44 with the docking block 8, thereby improving the applicable range.

[0048] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
