Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to a spray structure for a cutting saw. Background Technology

[0002] Cutting machines are widely used in construction decoration and stone processing, suitable for cutting brittle silicate non-metallic materials such as terrazzo, marble, granite, glass, and slabs made from liquid clay. Their advantages include high-efficiency cutting, excellent processing quality, ease of operation, and reduced labor intensity. When cutting hard materials like stone, cooling the saw blade is crucial to ensure its longevity. Currently, most cutting machines on the market achieve cooling by mounting spray heads on the blade guard; however, these spray heads generally suffer from insufficient sealing and complex, cumbersome installation processes. Therefore, it is necessary to design a new sealed installation structure for the cutting machine's spray head and develop a cutting machine incorporating this structure.

[0003] The prior art publication number "CN215039130U" mentions a sealing installation structure for a cutting machine spray head and a cutting machine containing this structure. The sealing installation structure includes a blade guard, a spray head, and an adapter. The blade guard has a connecting through hole on its side wall; the spray head has a connecting rod with a clamping block at one end and a spray nozzle at the other end; the adapter has at least one pipe joint, and the adapter has a through-flow liquid storage chamber inside, with the flow channel opening of the at least one pipe joint communicating with the liquid storage chamber; wherein, the end of the connecting rod with the spray nozzle passes through the liquid storage chamber and is threadedly connected to the connecting through hole; the clamping block seals one end opening of the liquid storage chamber, and the side wall seals the other end opening of the liquid storage chamber; the spray nozzle communicates with the liquid storage chamber to achieve the function of cooling the cutting machine. However, the sealing installation structure of the spray head in the above structure is too complex, especially the connecting rod, which requires additional secondary processing. Utility Model Content

[0004] The purpose of this invention is to provide a spray structure for a cutting saw, which uses standard screws to achieve a sealed installation between the adapter and the cutting blade cover, thereby simplifying processing and saving costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a spray structure for a cutting saw, the cutting saw including a cutting blade cover, a spray nozzle on the side wall, a connecting part on the outer surface of the side wall, the spray nozzle being located outside the connecting part, the spray structure including an adapter and fasteners, the adapter including at least one pipe joint, the adapter including an adapter sleeve sleeved outside the spray nozzle, the adapter sleeve forming a liquid storage cavity connecting the pipe joint and the spray nozzle inside, the bottom wall of the liquid storage cavity having a perforation and a first sealing part surrounding the perforation, the fastener passing through the perforation and locking with the connecting part, so that the first sealing part and the connecting part achieve an annular seal to isolate the liquid storage cavity and the fastener, and to achieve an annular seal between the adapter sleeve and the side wall.

[0006] After adopting the above technical solution, the present invention has the following advantages: The cutting blade cover is provided with a spray nozzle, which is connected to the liquid storage chamber of the adapter. Coolant is introduced into the liquid storage chamber through the pipe joint on the adapter and then flows out from the spray nozzle. The adapter is fixedly installed on the cutting blade cover by fasteners. The fasteners are generally standardized structures, so they are more applicable and do not need to be produced separately, saving production costs. At the same time, the installation is simpler and the installation difficulty is reduced. The adapter is also provided with an adapter sleeve for forming the liquid storage chamber. When the fastener passes through the through hole of the adapter sleeve and is fixed to the cutting blade cover, the first sealing part abuts against the connecting part, so that the liquid storage chamber and the fastener are isolated, and the seal between the two is more stable, ensuring that the coolant will not leak.

[0007] Furthermore, the fastener is a screw, and the connecting part is provided with a threaded hole that mates with the screw thread.

[0008] Furthermore, the first sealing part is a support member protruding above the bottom wall of the liquid storage cavity. The support member has an installation through hole for the screw to pass through. The tail of the screw passes through the installation through hole and is threaded into the threaded hole. The head of the screw abuts against one end of the adapter to fix the adapter head and the cutting blade cover.

[0009] Using the aforementioned technical solution, the tail of the screw passes through the mounting through hole of the support and is threaded into the corresponding threaded hole on the cutting disc cover. As the screw is tightened, the head of the screw abuts against one end of the adapter, causing the support to abut against the connecting part, thus fixing the adapter and the cutting disc cover. This connection method is not only simple and convenient, but also increases the connection strength between the two.

[0010] Furthermore, the outer end face of the connecting part forms a first sealing surface, and the end face of the support member forms a second sealing surface. The second sealing surface abuts against the first sealing surface to form a seal.

[0011] By adopting the aforementioned technical solution, the tight contact between the first sealing surface and the second sealing surface forms an effective seal between the inner side of the adapter and the cutting blade cover, reducing the risk of coolant leaking into the screw.

[0012] Furthermore, the second sealing surface is provided with a first annular sealing boss protruding towards the first sealing surface. The first annular sealing boss circumferentially surrounds the outside of the mounting through hole and abuts against the first sealing surface to achieve a seal between the first sealing surface and the second sealing surface.

[0013] Using the aforementioned technical solution, when the screw passes through the mounting through hole of the support and is threaded into the threaded hole, the first annular sealing boss will press against the first sealing surface, ensuring the sealing effect between the first sealing surface and the second sealing surface.

[0014] Furthermore, the end face of the adapter sleeve forms a third sealing surface, which abuts against the outer side of the cutting blade cover to form an annular seal. The third sealing surface is provided with a second annular sealing boss protruding towards the cutting blade cover. The second annular sealing boss surrounds the outside of the liquid storage cavity and abuts against the cutting blade cover.

[0015] Using the aforementioned technical solution, the third sealing surface presses against the cutting disc cover, forming an effective seal between the outer side of the adapter sleeve and the cutting disc cover, preventing coolant from leaking to the outer side of the adapter sleeve. When the screw passes through the mounting through hole of the support and is threaded into the threaded hole, the second annular sealing boss presses against the third sealing surface, ensuring the sealing effect between the third sealing surface and the cutting disc cover.

[0016] Furthermore, the spray structure includes a water pipe, and a sealing ring is provided on the outer wall of the pipe joint. The pipe joint extends into the water pipe so that the sealing ring is interference-fitted with the inner wall of the water pipe.

[0017] Using the aforementioned technical solution, the pipe joint is equipped with a sealing ring that is interference-fitted with the water pipe to achieve a sealing purpose, which effectively prevents coolant from leaking from the gap between the pipe joint and the water pipe. At the same time, this sealing method does not require the addition of other sealing structures, simplifying the installation steps and reducing installation costs.

[0018] Furthermore, the adapter has at least one limiting part on its side wall, and the cutting blade cover has a limiting groove that matches the limiting part. The limiting part is connected to the corresponding limiting groove to restrict the adapter from rotating relative to the cutting blade cover.

[0019] By adopting the aforementioned technical solution, the matching connection between the limiting part and the limiting groove ensures that the adapter cannot rotate relative to the cutting blade cover after installation, preventing problems such as loose connection and coolant leakage inside the adapter due to accidental rotation of the adapter. At the same time, the setting of the limiting groove ensures that the installation position of the adapter on the cutting blade cover is unique, thereby improving installation efficiency.

[0020] Furthermore, a cutting saw has the aforementioned spray structure.

[0021] Furthermore, the adapter includes a first adapter and a second adapter. The first adapter is installed on one side of the cutting blade cover, and the second adapter is installed on the other side of the cutting blade cover. The first adapter has two pipe connectors, and the second adapter has one pipe connector. The water pipe includes an inlet pipe and a connecting pipe. One pipe connector on the first adapter is connected to the inlet pipe, and the other pipe connector is connected to the pipe connector of the second adapter through the connecting pipe.

[0022] Using the aforementioned technical solution, the two ends of the cutting blade cover are respectively equipped with a first adapter and a second adapter. The first adapter has two pipe joints, one of which is connected to the water inlet pipe and the other is connected to the connecting water pipe. The pipe joint of the second adapter is connected to the other end of the connecting water pipe to achieve communication between the coolant in the first adapter and the second adapter. This installation method facilitates the circulation of coolant. At the same time, only one end needs to be connected to the cooling water source to achieve cooling at both ends simultaneously, reducing space occupation and making the equipment lighter and easier to install.

[0030] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0031] like Figures 1 to 4 As shown, this utility model provides a spray structure for a cutting saw 1. The cutting saw 1 includes a cutting blade cover 11. A spray nozzle 111 is provided on the side wall of the cutting blade cover 11. A connecting part 115 is provided on the outer surface of the side wall of the cutting blade cover 11. The spray nozzle 111 is located outside the connecting part 115. The spray structure includes an adapter 2 and fasteners. The adapter 2 has at least one pipe joint. The adapter 2 includes an adapter sleeve 28 sleeved on the outside of the spray nozzle 111. A liquid storage chamber 23 is formed inside the adapter sleeve 28, which connects the pipe joint and the spray nozzle 111. The bottom wall of the liquid storage chamber 23 is provided with a perforation and a first sealing part arranged around the perforation. The fastener passes through the perforation and locks with the connecting part 115, so that the first sealing part and the connecting part 115 achieve an annular seal to isolate the liquid storage chamber 23 and the fastener, and to achieve an annular seal between the adapter sleeve 28 and the side wall of the cutting blade cover 11.

[0032] Understandably, the cutting blade cover 11 is provided with a spray nozzle 111, which is connected to the liquid storage chamber 23 of the adapter 2. Coolant is introduced into the liquid storage chamber 23 through the pipe joint on the adapter 2 and then flows out from the spray nozzle 111. The adapter 2 is fixedly installed on the cutting blade cover 11 by fasteners. The fasteners are generally standardized structures, so they are more applicable and do not need to be produced separately, saving production costs. At the same time, the installation is simpler and the installation difficulty is reduced. The adapter 2 is also provided with an adapter sleeve 28 for forming the liquid storage chamber 23. When the fastener passes through the through hole of the adapter sleeve 28 and is fixed to the cutting blade cover 11, it abuts against the connecting part 115 through the first sealing part, so that the liquid storage chamber 23 and the fastener are isolated, and the seal between the two is more stable, ensuring that the coolant will not leak.

[0033] It should be noted that the cutting saw 1 includes a cutting blade guard 11 and a blade 12. The cutting blade guard 11 partially encloses the blade 12. Each of the opposite sides of the side wall of the cutting blade guard 11 is provided with a spray nozzle 111. The spray structure includes an adapter 2 and fasteners. In this embodiment, the fastener is a screw. The connecting part 115 is provided with a threaded hole that engages with the screw thread. In other embodiments, the fastener can also be a bolt and nut or a screw and adapter sleeve snap-fit ​​engagement.

[0034] According to the above, in one embodiment, the outer end face of the connecting portion 115 is flush with the outer side of the cutting blade cover 11, and the first sealing portion extends toward the cutting blade cover 11 to the outer end face of the connecting portion 115 and forms an annular seal therewith to isolate the liquid storage chamber 23 and the fastener.

[0035] In another embodiment, the bottom surface of the liquid storage cavity 23 forms a first sealing portion, and the connecting portion 115 extends toward the bottom surface of the liquid storage cavity 23 to form an annular seal thereon to isolate the liquid storage cavity 23 and the fastener.

[0036] In another embodiment, a cutting saw 1 is mentioned, which also has the above-described spray structure. The adapter 2 includes a first adapter 21 and a second adapter 22. The first adapter 21 is installed on one side of the cutting blade guard 11, and the second adapter 22 is installed on the other side of the cutting blade guard 11. The first adapter 21 is provided with two pipe joints, and the second adapter 22 is provided with one pipe joint. The water pipe 4 includes an inlet pipe 41 and a connecting water pipe 42. One pipe joint on the first adapter 21 is connected to the inlet pipe 41, and the other pipe joint is connected to the pipe joint of the second adapter 22 through the connecting water pipe 42.

[0037] Specifically, the two ends of the cutting blade cover 11 are respectively provided with a first adapter 21 and a second adapter 22. The first adapter 21 is provided with two pipe joints, one of which is connected to the water inlet pipe 41 and the other is connected to the connecting water pipe 42. The pipe joint of the second adapter 22 is connected to the other end of the connecting water pipe 42 to realize the communication between the coolant in the first adapter 21 and the second adapter 22. This installation method facilitates the circulation of coolant. At the same time, only one end needs to be connected to the cooling water source to achieve cooling at both ends at the same time, reducing space occupation and making the equipment lighter and easier to install.

[0038] For example, in a cutting saw 1, the adapter 2 includes a first adapter 21 and a second adapter 22. The first adapter 21 is installed on one side of the cutting blade guard 11, and the second adapter 22 is installed on the other side of the cutting blade guard 11. The first adapter 21 is provided with a first pipe interface 211 and a second pipe interface 212. The first pipe interface 211 and the second pipe interface 212 are located on the same straight line, and both the first pipe interface 211 and the second pipe interface 212 are connected to the liquid storage chamber 23. The water pipe 4 includes a water inlet pipe 41 and a connecting water pipe 42. The first pipe interface 211 is connected to the water inlet pipe 41, and the second pipe interface 212 is connected to one end of the connecting water pipe 42. The second adapter 22 includes a third pipe interface 221, which is connected to the other end of the connecting water pipe 42 to connect to the second pipe interface 212.

[0039] As can be seen from the above, the two ends of the cutting blade cover 11 are respectively provided with a first adapter 21 and a second adapter 22. The first adapter 21 is provided with a first pipe interface 211 and a second pipe interface 212, both of which are connected to the liquid storage chamber 23. The second adapter 22 is provided with a third pipe interface 221. The second pipe interface 212 and the third pipe interface 221 are connected by a water pipe 42. The coolant flows from the water pipe 4 through the first pipe interface 211 into the liquid storage chamber 23 and then from the liquid storage chamber 23 to the second pipe interface 212.

[0040] Specifically, the adapter 2 has at least one limiting part 25 on its side wall, and the cutting blade cover 11 has a limiting groove 112 that matches the limiting part 25. The limiting part 25 is connected to the corresponding limiting groove 112 to restrict the adapter 2 from rotating relative to the cutting blade cover 11. The matching connection between the limiting part 25 and the limiting groove 112 ensures that the adapter 2 cannot rotate relative to the cutting blade cover 11 after installation, preventing problems such as loose connection and coolant leakage in the adapter 2 caused by accidental rotation of the adapter 2. At the same time, the setting of the limiting groove 112 makes the installation position of the adapter 2 on the cutting blade cover 11 unique, improving the installation efficiency.

[0041] Preferably, in this embodiment, both the first adapter 21 and the second adapter 22 are provided with two limiting parts 25, which are respectively placed on opposite sides of the first adapter 21 and the second adapter 22.

[0042] When the screw 3 passes through the hole of the adapter sleeve 28, an annular liquid storage cavity 23 is formed inside the adapter sleeve 28. The annular liquid storage cavity 23 and the screw 3 are coaxially arranged.

[0043] The screw 3 passes through the through hole of the adapter sleeve 28 to fix the adapter 2 to the cutting blade cover 11. The first sealing part is a support member 24 protruding above the bottom wall of the liquid storage chamber 23. The support member 24 has a mounting through hole 241 for the screw 3 to pass through. In this embodiment, the through hole of the adapter sleeve 28 and the mounting through hole 241 have the same structure. The tail of the screw 3 passes through the mounting through hole 241 and is threaded to the threaded hole 113. The head of the screw 3 abuts against one end of the adapter 2 to fix the adapter to the cutting blade cover 11. The tail of the screw 3 passes through the mounting through hole 241 of the support member 24 and is threaded to the threaded hole 113 at the corresponding position on the cutting blade cover 11. As the screw 3 is tightened, the head of the screw 3 abuts against one end of the adapter 2, so that the support member 24 abuts against the connecting part 115, thereby fixing the adapter 2 to the cutting blade cover 11. This connection method is not only simple and convenient, but also increases the connection strength between the two.

[0044] Specifically, the outer end face of the connecting part 115 forms a first sealing surface 114, and the end face of the support member 24 forms a second sealing surface 242. The second sealing surface 242 abuts against the first sealing surface 114 to form a seal. The tight abutment between the first sealing surface 114 and the second sealing surface 242 forms an effective seal between the inner side of the adapter 2 and the cutting blade cover 11, reducing the risk of coolant leaking into the screw 3.

[0045] Preferably, the second sealing surface 242 is provided with a first annular sealing boss 243 protruding towards the first sealing surface 114. The first annular sealing boss 243 surrounds the outside of the mounting through hole 241. The first annular sealing boss 243 abuts against the first sealing surface 114 to achieve a seal between the first sealing surface 114 and the second sealing surface 242. When the screw 3 passes through the mounting through hole 241 of the support member 24 and is threadedly connected to the threaded hole 113, the first annular sealing boss 243 will abut against the first sealing surface 114, ensuring the sealing effect between the first sealing surface 114 and the second sealing surface 242.

[0046] Specifically, the end face of the adapter sleeve 28 forms a third sealing surface 26, which abuts against the outer side of the cutting blade cover 11 to form an annular seal, thereby forming an effective seal between the outer side of the adapter 2 and the cutting blade cover 11, preventing coolant from leaking to the outer side of the adapter 2.

[0047] Preferably, the third sealing surface 26 is provided with a second annular sealing boss 261 protruding towards the cutting blade cover 11. The second annular sealing boss 261 circumferentially surrounds the outside of the liquid storage cavity 23 and abuts against the cutting blade cover 11. When the screw 3 passes through the mounting through hole 241 of the support member 24 and is threadedly connected to the threaded hole 113, the second annular sealing boss 261 will abut against the third sealing surface 26, ensuring the sealing effect between the third sealing surface 26 and the cutting blade cover 11.

[0048] Specifically, the spray structure includes a water pipe 4, and a sealing ring 27 is provided on the outer wall of the pipe joint. The pipe joint extends into the water pipe 4 so that the sealing ring 27 is press-fitted with the inner wall of the water pipe 4. The pipe joint is provided with a sealing ring 27 that press-fits with the water pipe 4 to achieve the purpose of sealing, which effectively prevents coolant from leaking from the gap between the pipe joint and the water pipe 4. At the same time, this sealing method does not require the addition of other sealing structures, simplifies the installation steps, and reduces the installation cost.

[0049] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
