Description

Technical Field

[0001] This utility model belongs to the field of caliper cutting technology, and in particular relates to a caliper cutting tool with a cooling structure. Background Technology

[0002] Caliper cutting tools are tools used in machining to perform cutting, milling, boring, and other operations on calipers. These tools typically include non-standard milling cutters, boring tools, reamers, etc., and are specifically designed to machine various features of calipers, such as bushings, piston holes, and sealing grooves.

[0003] Patent CN222243866U discloses a metal cutting tool with coolant supply, including a connecting shaft and a cutting tool body fixed to the bottom of the connecting shaft. The surface of the cutting tool body has a drain hole. A cooling mechanism is connected to the surface of the connecting shaft, a connecting rod is connected to the surface of the cooling mechanism, and a liquid inlet is connected to the surface of the cooling mechanism. The cooling mechanism includes a fixed block, a connecting block, and a rotating block. This invention, through the connection between the through-slot and the drain hole, allows coolant to flow easily from the drain hole to the surface of the cutting tool body, thereby cooling the cutting tool body. It also prevents coolant residue from remaining in the through-slot and hindering its flow. Furthermore, the filters inside the connecting pipe and the flow pipe facilitate the filtration of the coolant, preventing sediment from flowing onto the surface of the cutting tool body and causing scratches when the cutting tool body cuts the workpiece.

[0004] However, in implementing the relevant technology, the above-mentioned solutions have the following problems: uneven cooling effect, the coolant cannot effectively cover the outer surface of the milling cutter, resulting in the heat generated during the cutting process not being dissipated in time, thus affecting the surface finish and machining quality. At the same time, the temperature of the cutting tool teeth may rise, thereby accelerating tool wear and shortening the service life of the milling cutter. Therefore, a caliper cutting tool with a cooling structure is proposed to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0033] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0034] Please see Figure 1-5 This utility model is a caliper cutting tool with a cooling structure, including a tool body 100 and a cooling assembly 200. The cooling assembly 200 includes a channel mechanism 201 and a flow guiding mechanism 202. The channel mechanism 201 is formed on the tool body 100, and the flow guiding mechanism 202 is disposed on the outer side wall of the tool body 100. The channel mechanism 201 includes a heat dissipation channel 2011, multiple water inlets 2012, a flow guiding groove 2013 and multiple rows of drain outlets 2014. The flow guiding mechanism 202 includes a flow guiding shell 2021 and two hand-tightening screws 2022.

[0035] Specifically, the heat dissipation channel 2011 is located at the center of the tool body 100, the flow guide groove 2013 is located on the outside of the tool body 100, multiple water inlets 2012 are arranged in a circular array on the outside of the tool body 100, and the water inlets 2012 are located inside the flow guide mechanism 202. The two ends of the water inlets 2012 are connected to the heat dissipation channel 2011 and the flow guide groove 2013 respectively. Multiple rows of drain outlets 2014 are arranged in a circular array on the tool head of the tool body 100. The flow guide shell 2021 is sleeved on the outer wall of the tool body 100, and the flow guide shell 2021 is located outside the water inlets 2012. Two hand-tightened screws 2022 are threaded onto the flow guide shell 2021, and the screw end of the flow guide shell 2021 abuts against the tool body 100.

[0036] The operation process of this embodiment is as follows: In use, the guide shell 2021 is manually fitted onto the tool body 100, and then the hand screw 2022 is turned so that its screw end tightly contacts the tool body 100, thereby allowing the guide shell 2021 to be stably fixed on the tool body 100. Then, when the coolant enters the guide groove 2013, it flows through the water inlet 2012, allowing the coolant in the guide groove 2013 to flow simultaneously to the heat dissipation channel 2011 and the outside of the tool body 100. Then, with the cooperation of the guide mechanism 202, the coolant flowing to the outside of the tool body 100 can be blocked, ensuring that the coolant flowing to the outside of the tool body 100 can flow to the outer surface of the tool body 100 under the guidance of the guide shell 2021. This achieves the combination of internal and external cooling, improves the overall cooling effect, and also forms a lubricating film between the tool and the workpiece, reducing friction, inhibiting adhesive wear, and further extending the service life of the tool body 100.

Multiple T-shaped grooves are sequentially formed on the T-shaped sleeve 401 in a circular array. The first splash shield 402 is fitted onto the outer side of the T-shaped sleeve 401. Multiple T-shaped plates 403 are sequentially fixedly installed on the inner side of the first splash shield 402 in a circular array, and the T-shaped plates 403 are interlocked with the T-shaped grooves. The second splash shield 404 is fitted onto the outer side of the first splash shield 402. Multiple limiting blocks 405 are sequentially fixedly installed on the inner side of the second splash shield 404 in a circular array. Multiple strip grooves 406 are sequentially formed on the outer wall of the first splash shield 402 in a circular array, and the limiting blocks 405 are interlocked with the strip grooves 406.

[0039] The operation process of this embodiment is as follows: the first splash guard 402 on the outside of the T-shaped sleeve 401 and the second splash guard 404 on the outside of the first splash guard 402 can effectively block the splashes of debris, coolant and other materials generated during the processing, thereby protecting the operator from potential injury and improving workplace safety. At the same time, the T-shaped sleeve 401 and the second splash guard 404 can extend and retract under the action of the T-groove, the T-plate 403, the limiting block 405 and the strip groove 406, thereby avoiding any impact on the use of the tool body 100.

Multiple water outlets 3013 are sequentially opened in a circular array at the bottom of the conveying shell 3011, and the water outlets 3013 are connected to the guide groove 2013. The annular sleeve 3021 is threadedly connected to the conveying shell 3011. Two annular frames 3022 are fixedly installed on the inner top wall of the annular sleeve 3021. The two annular frames 3022 are of different sizes. The smaller annular frame 3022 is located inside the larger annular frame 3022. The annular filter screen 3023 is fixedly installed in the middle of the two annular frames 3022. The bottom of the annular filter screen 3023 passes through the annular opening on the conveying shell 3011 and is located inside the conveying shell 3011. Two sealing gaskets 3024 are fixedly installed at the bottom of the two annular frames 3022 respectively.

[0042] The operation process of this embodiment is as follows: When in use, the water inlet pipe 3012 is connected to the external liquid supply pipe, so that the coolant can enter the delivery shell 3011 from the water inlet pipe 3012. Then, the coolant in the delivery shell 3011 is filtered by the annular filter screen 3023 and then enters the guide groove 2013 through the outlet 3013, so that the coolant can cool the tool body 100. At the same time, the sealing gasket 3024 at the bottom of the annular frame 3022 can prevent the coolant in the delivery shell 3011 from flowing out between the annular frame 3022 and the delivery shell 3011.
