Description

Technical Field

[0001] This utility model relates to the field of wood processing equipment technology, and in particular to a cutting machine with positioning function. Background Technology

[0002] Currently, precise length cutting of strip timber is a crucial step in the timber processing industry. Traditional timber cutting equipment generally suffers from low positioning accuracy when cutting strip timber. Specifically, existing cutting machines often lack a precise positioning structure, requiring operators to rely primarily on visual inspection or simple rulers for rough positioning. This makes it difficult to accurately control the cutting length, resulting in significant dimensional errors in the cut timber. Consequently, the cut timber is of inconsistent length, severely impacting the precision and efficiency of timber processing and failing to meet the stringent precision requirements of modern industrial production. Furthermore, the lack of an effective clamping and positioning mechanism during cutting allows the timber to easily shift under the cutting force, further reducing cutting accuracy and potentially leading to scrap and material waste. Therefore, existing technologies urgently need improvement to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cutting machine with positioning function.

By rotating the rotating handle, the positioning block can be driven to slide along the sliding groove, and the position of the positioning block is indicated by the pointer and the scale line, so as to adjust the position of the positioning block according to the length of the strip of wood that needs to be cut.

[0008] Preferably, the cutting component includes two vertical slide rods and a baffle. The two vertical slide rods are fixedly connected to the top of the cutting table. A fixing plate is fixedly connected to the top of the two vertical slide rods. An electric cylinder is fixedly connected to the top of the fixing plate.

The lifting frame is slidably mounted on the vertical slide rods. A motor is fixedly installed on the lifting frame. A cutting blade is fixedly connected to the end of the output shaft of the motor. The baffle is fixed on the lifting frame and located above the cutting blade.

[0009] Preferably, the clamping and positioning component includes a fixing rod, which is fixedly connected to the side wall of the lifting frame. Two vertical columns are provided through the top of the fixing rod, and a horizontal bar is fixedly connected to the top of the two vertical columns. A clamping plate is fixedly connected to the bottom of the two vertical columns. A spring is sleeved on each vertical column, and the two ends of the spring are fixedly connected to the bottom of the fixing rod and the top of the clamping plate, respectively.

[0010] Preferably, the cutting table is provided with a clearance groove, which is located directly below the cutting blade and is used to avoid the cutting blade.

[0017] Compared with existing technologies, this invention has the following advantages: By setting a measuring and positioning component, the position of the positioning block can be precisely adjusted, thereby accurately controlling the cutting length of the strip wood. This effectively solves the technical problem mentioned in the background art, where traditional cutting machines lack a precise positioning structure, leading to large errors in the cutting length of the wood. Specifically, the measuring and positioning component utilizes the ingenious cooperation of a rotating handle, scale lines, positioning blocks, sliding grooves, pointers, and horizontal threaded rods to achieve precise sliding and positioning of the positioning block within the sliding groove.

[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] Application Scenario: In the field of wood processing technology, precise length cutting of strip timber is crucial. However, traditional cutting equipment has long suffered from significant limitations in precise positioning. Early cutting operations relied heavily on manual visual inspection and experience, making errors in cutting dimensions unavoidable, especially in mass production scenarios with high precision requirements, where traditional methods proved inadequate. To improve cutting accuracy, some cutting equipment with simple positioning structures has been developed, but these structures are often rudimentary in design, offering limited improvement in accuracy and failing to fundamentally solve the problem. To address the issue of low precision in strip timber cutting, this application proposes a cutting machine with positioning functionality, aiming to overcome the shortcomings of existing technologies and achieve high-precision cutting of strip timber. This cutting machine cleverly integrates a measuring positioning component 5 and a clamping positioning component 4, ensuring cutting accuracy while also improving the stability of the cutting process, providing the wood processing industry with an efficient and precise cutting solution.

[0028] like Figures 1 to 7 The cutting machine shown includes a cutting table 2, and further includes:

[0029] Cutting component 3 is positioned above cutting table 2;

[0030] Two clamping and positioning components 4 are symmetrically arranged below the cutting component 3 to clamp and position the strip of wood during cutting;

[0031] The measuring and positioning component 5 includes a rotating handle 501, a scale line 502, a positioning block 503, a sliding groove 504, a pointer 505, and a horizontal threaded rod 506. The sliding groove 504 is disposed on the cutting table 2. The positioning block 503 is disposed in the sliding groove 504 and can slide along the sliding groove 504. The horizontal threaded rod 506 is rotatably disposed on the inner wall of the sliding groove 504. The positioning block 503 is threadedly connected to the horizontal threaded rod 506. The rotating handle 501 is fixedly connected to one end of the horizontal threaded rod 506. The pointer 505 is fixed on the positioning block 503. The scale line 502 is disposed on the top of the cutting table 2 and located below the pointer 505. By rotating the rotating handle 501, the positioning block 503 can be driven to slide along the sliding groove 504. The position of the positioning block 503 is indicated by the pointer 505 and the scale line 502, so as to adjust the position of the positioning block 503 according to the length of the strip of wood that needs to be cut.

[0032] In practical implementation, the strip of wood is first placed on the cutting table 2, with one end resting against the positioning block 503. Then, the cutting component 3 is activated, driving the cutting blade downwards to begin cutting the wood. Before the cutting blade contacts the wood, the clamping positioning component 4 clamps and fixes the wood to ensure it does not shift during cutting. As cutting progresses, the cutting blade gradually cuts through the wood, ultimately completing the cutting operation. Through the synergistic effect of the measuring positioning component 5 and the clamping positioning component 4, the cutting machine of this application can achieve high-precision and stable cutting of strips of wood, effectively solving the problems of low cutting accuracy and unstable quality in the prior art.

[0033] Compared with existing technologies, the cutting machine with positioning function of this application has significant advantages. Traditional wood cutting machines rely mainly on manual visual inspection or simple mechanical baffles for positioning during length cutting, resulting in low positioning accuracy and large cutting errors, making it difficult to meet the requirements of high-precision cutting. This application, through its innovative measuring and positioning component 5, achieves precise adjustment and visualization of the cutting length, significantly improving positioning accuracy and reducing cutting errors. Furthermore, in existing cutting machines, the wood is prone to displacement during the cutting process, leading to a decline in cutting quality. This application, by setting up a clamping positioning component 4, pre-clamps the wood before cutting, effectively preventing wood displacement, improving cutting stability, and ensuring cutting quality. Therefore, the cutting machine with positioning function of this application significantly improves both cutting accuracy and cutting quality compared to existing technologies, meeting the demands of the modern wood processing industry for high-precision, high-quality cutting.

[0034] In one embodiment of this utility model, the cutting component 3 includes two vertical slide rods 305 and a baffle 303. The two vertical slide rods 305 are fixedly connected to the top of the cutting table 2. A fixing plate 301 is fixedly connected to the top of the two vertical slide rods 305. An electric cylinder 302 is fixedly connected to the top of the fixing plate 301. The telescopic end of the electric cylinder 302 passes through the fixing plate 301 and extends downward to be fixedly connected to a lifting frame 304. The lifting frame 304 is slidably mounted on the vertical slide rods 305. A motor 307 is fixedly installed on the lifting frame 304. A cutting blade 306 is fixedly connected to the end of the output shaft of the motor 307. The baffle 303 is fixed on the lifting frame 304 and located above the cutting blade 306.

[0035] In practical implementation, the cutting component 3 adopts a double vertical slide bar 305 structure. The two vertical slide bars 305 are fixedly connected to the top of the cutting table 2, serving as guide supports for the lifting mechanism. The specific fixing method for the vertical slide bars 305 can be varied, such as by bolts, welding, or snap-fitting, as long as the stability of the vertical slide bars 305 is ensured. To further enhance the overall strength of the structure, the tops of the two vertical slide bars 305 are connected by a fixing plate 301. The fixing plate 301 can be made of materials with sufficient strength, such as steel or aluminum plates, with its two ends fixedly connected to the tops of the two vertical slide bars 305 respectively, and the middle part used to install the drive mechanism. The electric cylinder 302, as the power source for the cutting component 3, is fixed to the top of the fixing plate 301. The telescopic end of the electric cylinder 302 passes downward through the fixing plate 301 and is fixedly connected to the lifting frame 304. The lifting frame 304 is slidably mounted on the vertical slide bars 305 and can move up and down along the length of the vertical slide bars 305. Motor 307 is fixedly mounted on lifting frame 304, serving as the drive device for cutting blade 306. Cutting blade 306 is fixedly connected to the output shaft end of motor 307, rotating at high speed with the operation of motor 307 to achieve the cutting function. Guard 303 is fixed on lifting frame 304 and located above cutting blade 306; its function is to block flying sawdust and debris during cutting, improving operational safety.

[0036] In one embodiment of this utility model, the clamping and positioning component 4 includes a fixing rod 405, which is fixedly connected to the side wall of the lifting frame 304. Two vertical columns 402 are provided through the top of the fixing rod 405. A horizontal bar 404 is fixedly connected to the top of the two vertical columns 402. A clamping plate 401 is fixedly connected to the bottom of the two vertical columns 402. A spring 403 is sleeved on each vertical column 402. The two ends of the spring 403 are fixedly connected to the bottom of the fixing rod 405 and the top of the clamping plate 401, respectively.

[0037] In practical implementation, the fixing rod 405 is fixedly connected to the side wall of the lifting frame 304, serving as the mounting base for the clamping and positioning component 4. It is understood that the fixing method between the fixing rod 405 and the lifting frame 304 can be bolted, welded, or integrally formed, ensuring a firm and reliable connection. Two vertical columns 402 are provided through the top of the fixing rod 405, and the vertical columns 402 can slide along the vertical direction of the fixing rod 405. To limit the sliding range of the vertical columns 402, a horizontal bar 404 is fixedly connected to the top of both vertical columns 402. The horizontal bar 404 can be made of metal or other materials with sufficient strength, and its two ends are fixedly connected to the tops of the two vertical columns 402 respectively, forming a stable frame structure. A clamping plate 401 is fixedly connected to the bottom of the two vertical columns 402. The clamping plate 401 is the component that directly contacts the strip of wood, and its bottom surface can be provided with anti-slip textures or a soft material layer to increase friction with the wood and improve the clamping effect. Each vertical column 402 is fitted with a spring 403, which is compressed between the bottom of the fixing rod 405 and the top of the clamping plate 401. Understandably, the spring constant of the spring 403 can be selected according to the actual clamping requirements to ensure appropriate clamping force.

[0038] The design of spring 403 is crucial to the clamping and positioning component 4. The elastic force provided by spring 403 allows the clamping plate 401 to consistently apply a gentle and continuous pressure to the wood. Even when there are certain deviations in wood thickness, the clamping plate 401 can adaptively adjust through the extension and contraction of spring 403, ensuring the stability of the clamping effect and avoiding problems such as insufficient or excessive clamping due to uneven wood thickness. The cooperation of vertical column 402 and horizontal bar 404 provides guidance for the movement of clamping plate 401, ensuring the stability and straightness of clamping plate 401 during the clamping process.

[0039] Therefore, by employing the elastic clamping design of spring 403, the clamping and positioning component 4 can better adapt to wood of different thicknesses, ensuring a stable and reliable clamping effect. Compared to a simpler clamping mechanism, this clamping and positioning component 4 can provide a more uniform and stable clamping force, thereby further improving the stability and cutting quality of the cutting process and providing a more reliable guarantee for achieving high-precision wood cutting.

[0040] As one embodiment of this utility model, the cutting table 2 is provided with a clearance groove 8, which is located directly below the cutting blade 306 and is used to avoid the cutting blade 306.

[0041] In practical implementation, the shape and size of the clearance groove 8 can be adapted to the shape and size of the cutting blade 306. For example, if the cutting blade 306 is a circular saw blade, the clearance groove 8 can be designed as a strip groove or an arc groove, as long as it ensures that when the cutting blade 306 descends to its lowest position, the lower end of the cutting blade 306 can be accommodated in the clearance groove 8 without colliding with the surface of the cutting table 2. The depth of the clearance groove 8 also needs to be reasonably set according to the maximum cutting depth of the cutting blade 306 to ensure that after the cutting action is completed, the lower end of the cutting blade 306 is completely inserted into the clearance groove 8, avoiding interference with the cutting table 2. The lateral width of the clearance groove 8 should be slightly greater than the thickness of the cutting blade 306 to avoid friction between the cutting blade 306 and the side wall of the clearance groove 8 during the cutting process.

[0042] The structure of setting the clearance groove 8 on the cutting table 2, although simple, effectively solves the problem of potential interference between the cutting blade 306 and the cutting table 2, ensuring smooth cutting and extending the service life of the cutting blade 306. Compared with a cutting machine without the clearance groove 8, this cutting machine with the clearance groove 8 has significant advantages in cutting reliability and blade protection, providing further assurance for achieving stable and reliable wood cutting.

[0043] As one embodiment of this utility model, the cutting table 2 is also provided with a collecting hopper 6, which is located inside the clearance groove 8 and is used to collect the debris generated during the cutting process.

[0044] In its implementation, the design of the collection hopper 6 fully considers the cleanliness issues during the use of the cutting machine. During wood cutting, a large amount of sawdust, dust, and other debris is inevitably generated. If this debris is scattered on the workbench or floor, it not only affects the cleanliness of the working environment but may also pose a potential health hazard to the operators. By installing the collection hopper 6 on the cutting table 2, the debris generated during the cutting process can be effectively collected, preventing it from splashing and spreading, maintaining a clean and hygienic working environment, and providing operators with a cleaner and healthier working environment.

[0045] As one embodiment of this utility model, the collecting bucket 6 is provided with a notch 7, which is used to avoid strips of wood; by providing a notch 7 on the collecting bucket 6, strips of wood can be cleverly avoided, so that the collecting bucket 6 can effectively collect debris without hindering the normal cutting process.

[0046] As one embodiment of this utility model, a support leg 1 is fixedly connected to the bottom of the cutting table 2. The support leg 1 is used to support the cutting table 2; it can provide stable and reliable support for the cutting machine, prevent it from tipping over or shaking during use, and improve the safety and reliability of operation.

[0047] In one embodiment of this utility model, the sliding groove 504 is a T-shaped sliding groove, and the positioning block 503 is a T-shaped positioning block. The T-shaped positioning block is slidably disposed in the T-shaped sliding groove. By using the cooperation of the T-shaped sliding groove 504 and the T-shaped positioning block 503, the stability of the positioning block 503 during the sliding process can be effectively improved, and it can be prevented from shaking or tilting, thereby ensuring the positioning accuracy.

[0048] As one embodiment of this utility model, the scale line 502 on the top of the cutting table 2 is located on one side of the sliding groove 504; this allows the operator to more conveniently observe the relative position of the scale line 502 and the pointer 505 during operation, improving the convenience and accuracy of reading.

[0049] As one embodiment of this utility model, scale values ​​are provided on the scale line 502.

[0050] To further enhance the practicality and intuitiveness of the scale line 502, this application also sets scale values ​​on the scale line 502. By setting scale values ​​on the scale line 502, operators can more intuitively read the position information of the positioning block 503, quickly and accurately adjust the position of the positioning block 503, and further improve the positioning accuracy and operational efficiency.

[0051] Working principle of this utility model:

[0052] In use, the support leg 1 supports the cutting table 2. The fixing plate 301 is fixed to the top of the vertical sliding rod 305. The strip of wood to be cut is placed on the cutting table 2. The position of the positioning block 503 is adjusted according to the length of the wood to be cut. By rotating the handle 501 in the measuring positioning component 5, the horizontal threaded rod 506 is rotated. The rotation of the horizontal threaded rod 506 causes the positioning block 503 to slide along the sliding groove 504. During the movement of the positioning block 503, the pointer 505 moves synchronously. The pointer 505 points to the scale line 502. By observing the scale value on the scale line 502, when the pointer 505 points to the scale line 502... When the scale value on the cutting tool matches the length of the wood to be cut, the cutting tool stops. Then, one end of the wood is brought into contact with the positioning block 503. Next, the electric cylinder 302 and motor 307 in the cutting component 3 are activated. The telescopic end of the electric cylinder 302 extends downwards, causing the lifting frame 304 to slide downwards along the vertical slide bar 305. Simultaneously, the lifting frame 304 moves downwards, driving the clamping and positioning component 4 and the cutting blade 306 to move downwards in sync. As the clamping and positioning component 4 moves downwards, the clamping plate 401 first presses against the top of the wood, and the clamping plate 401 begins to clamp the wood. The electric cylinder 302 continues to drive the lifting frame 304 downwards, and the motor 307... The cutting blade 306 rotates to cut the wood. As the cutting blade 306 moves downwards, the clamping plate 401 remains pressed against the top of the wood. After the clamping plate 401 is blocked by the wood, the lifting frame 304 drives the fixing rod 405 to continue moving downwards. The fixing rod 405 slides downwards along the vertical column 402. At this time, the spring 403 is elastically compressed. When the resistance disappears, the elastic potential energy of the spring 403 is released, which can reset the clamping plate 401. During the cutting process, the clamping plate 401 first presses the wood on both sides of the cutting blade 306, improving the stability of the cutting process and ensuring that even after the wood is cut... It will not easily shift, improving cutting accuracy and preventing skewed cutting due to wood displacement. The crossbar 404 is fixed to the top of the two vertical columns 402, improving the stability of the connection between the vertical columns 402. The clearance groove 8 is used to avoid the cutting blade 306, and the collection hopper 6 is installed inside the clearance groove 8. The notch 7 is used to avoid the wood. Through the enclosure of the collection hopper 6 and the baffle 303, most of the debris thrown out along the tangential direction of the cutting blade 306 during the cutting process is blocked and falls into the collection hopper 6. A collection box is placed below the collection hopper 6 for collection, thereby reducing the pollution of the ground caused by the debris.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
