Description

Technical Field

[0001] The utility model relates to the technical field of oil injection devices, in particular to a low-temperature roller oil injection device. Background Art

[0002] A gear processing tool with teeth arranged in a spiral line along a cylinder or cone, used to process cylindrical gears, worm gears and other cylindrical toothed workpieces by the development method (see gear processing, gears). Depending on the purpose, hobs are divided into gear hobs, worm hobs, non-involute development hobs and fixed hobs.

[0003] For example, the patent with application number: 201921194693.7 discloses an oil injection and cooling device for gear processing tools, including an oil supply pipe and an oil distribution pipe, one end of the oil supply pipe is connected to an external oil pump, and the other end is connected to the middle part of the oil distribution pipe and communicated with the oil distribution pipe, both ends of the oil distribution pipe are closed, and a plurality of oil injection holes corresponding to the gear hob blades are formed at the bottom of the oil distribution pipe. The gear hob blade is cooled at a fixed point through the oil injection holes, thereby improving the uniformity of the temperature of different hob blades and extending the service life of the hob.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the above-mentioned structure opens a plurality of oil filling holes on the oil distribution pipe corresponding to the blade of the roller cutter, and transports cooling oil to the oil distribution pipe through the oil supply pipe connected in the middle part of the oil distribution pipe, and the oil drips from the oil filling holes onto the roller cutter for cooling. However, the middle part of the oil supply pipe is designed to transport oil to the oil distribution pipe, so that the delivery pressure of the oil filling holes in the middle part of the oil distribution pipe is large, while the delivery pressure at the two ends is small, which results in uneven amount of cooling oil dripping from the oil filling holes in the middle and end parts of the oil distribution pipe, resulting in inconsistent cooling effect on the roller cutter blade, affecting the service life. Therefore, a low-temperature roller cutter oiling device is proposed. Utility Model Content

[0023] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0024] Embodiment 1:

[0025] See also Figure 1-5 The utility model provides a low-temperature roller oiling device, comprising an internally hollow oil delivery seat 1 and an oil distribution pipe 2, wherein a plurality of oil delivery pipes 11 are installed on the oil delivery seat 1, and the oil delivery pipes 11 are placed close to the inner wall of the oil delivery seat 1, one end of the oil delivery pipe 11 is connected to the oil tank, and the other end of the oil delivery pipe 11 is connected to the oil distribution pipe 2, and the middle part and the end of the oil distribution pipe 2 are connected to the oil delivery pipe 11, so that the oil delivery pipe 11 evenly delivers cooling oil to the inside of the oil distribution pipe 2, ensuring that the plurality of oil delivery holes on the oil distribution pipe 2 22 can drip evenly, a plurality of oil delivery holes 22 are opened at the bottom of the oil distribution pipe 2, a connecting shaft 12 is rotatably installed in the oil delivery seat 1, and a plurality of rollers 13 are rotatably connected to the outer periphery of the connecting shaft 12 through a support rod, and the rollers 13 are tightly attached to the inner wall of the oil delivery seat 1, and the rollers 13 rotate and squeeze the oil delivery pipe 11 to deform, so that negative pressure is generated in the oil delivery pipe 11, thereby pushing the oil to move in the oil delivery pipe 11 and transport it to the oil distribution pipe 2, and a motor for driving the connecting shaft 12 to rotate is also installed at the outer end of the oil delivery seat 1.

[0026] Please pay attention to Figure 1 , Figure 4 , Figure 5 The oil pipeline 11 is a silicone hose, which has high tensile strength and extrusion strength, excellent wear resistance and anti-aging properties, and can extend the service life of the oil pipeline 11 under long-term extrusion use.

[0027] Please pay attention to Figure 4 A limit strip 15 for preventing the oil pipe 11 from shifting is installed at the position of the inner wall of the oil delivery seat 1 corresponding to the oil pipe 11. The limit strip 15 is arranged on both sides of the oil pipe 11. The cross-sectional shape of the limit strip 15 is semicircular. The limit strip 15 limits the oil pipe 11 to prevent the oil pipe 11 from shifting when squeezed and affecting normal oil delivery. The semicircular limit strip 15 avoids scratching the oil pipe 11.

[0028] Please pay attention to Figure 5 A layer of rubber pad is fixed on the outer wall of the roller 13, and the rubber pad is in contact with the oil pipeline 11. The contact between the rubber pad and the oil pipeline 11 protects the oil pipeline 11 and reduces the noise generated when the roller 13 rotates.

[0029] Please pay attention to Figure 3 The oil delivery hole 22 is arranged at the bottom of the oil delivery seat 1 along the length direction of the oil delivery seat 1. The position of the oil delivery hole 22 corresponds to the position of the blade of the roller. Through this design, the oil delivery hole 22 is aligned with the position of the roller blade to accurately drip cooling oil for cooling, thereby ensuring that the overall temperature of the roller is evenly reduced and cooled.

[0030] Please pay attention to Figure 4 An axial hole 14 is provided in the oil delivery seat 1, and the end of the connecting shaft 12 away from the motor is rotatably installed in the axial hole 14. The connecting shaft 12 is supported and limited by the axial hole 14 to ensure that the connecting shaft 12 rotates stably, thereby driving the roller 13 to stably squeeze the oil delivery pipe 11.

[0031] Please pay attention to Figure 1-2 A pipe joint 21 is installed in the middle and both ends of the oil delivery seat 1. One end of the pipe joint 21 is connected to the inside of the oil delivery seat 1, and the other end of the pipe joint 21 is plugged into the oil delivery pipe 11. A convex ring 211 is also installed on the outer wall of the pipe joint 21. The pipe joint 21 is used to facilitate disassembly and assembly of the oil delivery pipe 11 for cleaning. At the same time, the design of the convex ring 211 increases the sealing performance of the connection between the pipe joint 21 and the oil delivery pipe 11 to avoid oil leakage.

[0032] Please pay attention to Figure 1 The motor is a reduction motor 16, which is fixedly mounted on the side end of the oil delivery seat 1. The output shaft of the reduction motor 16 is fixedly connected to the connecting shaft 12. The connecting shaft 12 is driven to rotate by the rotation of the output shaft of the reduction motor 16. The rotation accuracy of the reduction motor 16 is high. The oil delivery amount can be accurately controlled by controlling the rotation speed of the output shaft of the reduction motor 16. The high torque load of the reduction motor 16 is large, which ensures that the connecting shaft 12 stably drives the roller 13 to squeeze the oil delivery pipe 11.

[0033] The working principle of the first embodiment of the utility model is as follows:

[0034] When in use, the reduction motor 16 is started, and the output shaft of the reduction motor 16 rotates to drive the connecting shaft 12 to rotate counterclockwise. The rotation of the connecting shaft 12 drives the roller 13 to rotate around the inner wall of the oil delivery seat 1. The roller 13 rolls closely against the inner wall of the oil delivery seat 1 and squeezes the oil delivery pipe 11 at the same time. The delivery pipe recovers its original shape after being squeezed by the roller 13, thereby forming a negative pressure vacuum, sucking the oil at the rear of the oil delivery pipe 11, and thus pumping the oil into the oil delivery pipe 11. At the same time, multiple rollers 13 roll and squeeze the oil delivery pipe 11 in turn. When multiple rollers 13 roll, at least one roller 13 is kept in contact with the oil delivery pipe 11 to squeeze it. The oil in the oil delivery pipe 11 is squeezed to the pipe joint 21 and enters the oil distribution pipe 2, and the oil is simultaneously delivered to the pipe joints 21 at the middle and both ends of the oil distribution pipe 2, and the delivered oil amount is consistent, so that the middle and both ends of the oil distribution pipe 2 are evenly input with oil, so that the oil delivery hole 22 at the bottom of the oil distribution pipe 2 drips the oil evenly, and the oil drips onto the blade of the roller for cooling. The even dripping of oil from the oil delivery hole 22 can ensure the uniformity of the overall cooling of the roller and extend the service life of the roller. The oil delivery amount can be controlled by controlling the speed of the output shaft of the reduction motor 16, which is practical.

[0035] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
