Description

Technical Field

[0001] The utility model relates to the technical field of pulley processing, in particular to a cutting device for making pulleys. Background Technique

[0002] The pulley belongs to the disk hub parts, generally with relatively large dimensions. Pulleys are mainly used in occasions where power is transmitted over a long distance, such as the power output of small diesel engines, agricultural vehicles, tractors, automobiles, mining machinery, machining equipment, etc. It should be noted that gasoline must be used for the last cleaning before assembling the pulley to ensure that all components are clean and dry, so as to ensure that the mating surfaces fit tightly and are free of oil stains, with sufficient friction. During the production and manufacturing of pulleys, in order to prevent the belt from running off, it is often necessary to use external equipment to open a ring groove. However, there are some problems with the existing cutting devices during use:

[0003] 1. Poor heat dissipation effect. During the cutting process, the cutting tool tip continuously contacts and rubs against the original material of the pulley for processing, thus generating a large amount of heat. However, during the processing of the existing cutting device, its simple flushing heat dissipation effect is not good, which will cause a large amount of heat to accumulate on the cutting tool. Therefore, long-term processing will affect the service life of the cutting tool.

[0004] 2. Poor recycling effect. During the cutting process, in order to achieve rapid cooling, it is necessary to continuously spray cold water for cooling. However, the existing spraying device directly sprays cold water, and the warmed warm water is directly discharged, which not only causes waste of water resources, but also directly discharges the metal chips mixed inside, which will also be wasted and cannot be recycled. Content of the Utility Model

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a cutting device for making pulleys.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A cutting device for making pulley, including a processing bottom shell, wherein the bottom inner wall of the processing bottom shell is provided with an inclined groove, and a support pedestal is welded on the inner wall at one end of the inclined groove, and a fixed bracket is welded on the inner wall at the other end of the inclined groove, and a cutting tool is arranged on the fixed bracket. A regulating screw rod is screwed in the middle of the support pedestal, and one end of the regulating screw rod is rotatably connected with a rotating connecting rod. A C-shaped clamping groove is formed at the end of the rotating connecting rod away from the regulating screw rod. The middle of the outer wall of one side of the processing bottom shell is fixed with a telescopic adjusting rod by screws, and an arc-shaped connecting pipe is arranged at the top of the telescopic adjusting rod. A communicating pipe is communicated with the inner wall of the arc-shaped connecting pipe, and a spherical inner shell is welded at the end of the communicating pipe. A spherical outer shell is sleeved on the outer wall of the spherical inner shell, and a spray head is welded on the inner wall of one side of the spherical outer shell. A connecting hose is fixed at one side pipe orifice of the arc-shaped connecting pipe by a hoop, and a micro-lifting pump is arranged at the other end of the connecting hose. The micro-lifting pump is communicated with a water collecting shell, and a protective outer shell is clamped and fixed on the top of the processing bottom shell.

[0008] As a further scheme of the utility model: A limiting sleeve is arranged on the outer wall of the rotating connecting rod, and limiting sliding grooves are formed on the inner walls of both sides of the limiting sleeve.

[0009] As a further scheme of the utility model: Limiting sliding blocks are welded on the outer walls of both sides of the end of the rotating connecting rod, and the limiting sliding blocks form a sliding fit with the limiting sliding grooves.

[0010] As a further scheme of the utility model: A T-shaped clamping block is clamped and arranged on the inner wall of the C-shaped clamping groove, and a conical pressing plug is welded on the outer wall of the T-shaped clamping block.

[0014] As a further scheme of the utility model: The cutting tool and the spray head are located in the same vertical plane, and the spray head is located at the lower left of the cutting tool.

[0015] Compared with the prior art, the utility model provides a cutting device for making pulley, which has the following beneficial effects:

[0016] 1. The pulley cutting device of this design can effectively improve the cooling effect by arranging three groups of spray nozzles on the side of the cutting tool to spray cold water. And the three groups of spray nozzles adopt an interference fit design and can be rotated at will, so as to meet the spraying and cooling at multiple angles, greatly improving the practicability of the device.

[0017] 2.

A regulating screw rod 6 is screwed in the middle of the support pedestal 3, and one end of the regulating screw rod 6 is rotatably connected to a rotating connecting rod 7. A C-shaped clamping groove 8 is opened at the end of the rotating connecting rod 7 away from the regulating screw rod 6. A telescopic adjusting rod 14 is fixed to the middle of the outer wall of one side of the processing bottom shell 1 by screws, and an arc-shaped connecting pipe 15 is arranged at the top of the telescopic adjusting rod 14. A communicating pipe 16 is communicated with the inner wall of the arc-shaped connecting pipe 15, and a spherical inner shell 17 is welded to the end of the communicating pipe 16. A spherical outer shell 18 is sleeved on the outer wall of the spherical inner shell 17, and a spray head 19 is welded to the inner wall of one side of the spherical outer shell 18. A connecting hose 20 is fixed to one side pipe orifice of the arc-shaped connecting pipe 15 by a hoop, and a micro lift pump 21 is arranged at the other end of the connecting hose 20. The micro lift pump 21 is communicated with a water collecting shell 22. A protective outer shell 23 is clamped and fixed on the top of the processing bottom shell 1;

[0028] By arranging three groups of spray heads 19 on the side of the cutting tool 5 to spray cold water, the cooling effect can be effectively improved. And the three groups of spray heads 19 adopt an interference fit design and can be rotated at will, so as to meet the spraying and cooling at multiple angles, greatly improving the practicability of the device.

[0029] A limiting sleeve 9 is arranged on the outer wall of the rotating connecting rod 7, and limiting sliding grooves 10 are opened on the inner walls of both sides of the limiting sleeve 9. Limiting sliding blocks 11 are welded to the outer walls of both ends of the rotating connecting rod 7, and the limiting sliding blocks 11 form a sliding fit with the limiting sliding grooves 10;

[0030] A T-shaped clamping block 12 is clamped and arranged on the inner wall of the C-shaped clamping groove 8, and a conical pressing plug 13 is welded to the outer wall of the T-shaped clamping block 12.

[0031] The outer wall size of the spherical inner shell 17 is adapted to the inner wall size of the spherical outer shell 18, and the spherical inner shell 17 and the spherical outer shell 18 form an interference fit;

[0032] After spraying cold water to cool down, the inclined groove 2 structure arranged at the bottom can quickly gather the warm water and discharge it from the bottom.

After fixing, start the cutting tool 5 at the top to process the pulley by cutting. When processing, start the micro lift pump 21 at the bottom to continuously pump out the cold water and spray it through the nozzle 19 to spray cold water to cool down the cutting tool 5. According to the processing path and size, the nozzle 19 can be rotated at will for angle adjustment, so as to realize rapid and effective cooling. The metal chips generated during the cutting process will gather from the inclined groove 2 at the bottom and be discharged from the chip discharge pipe 24 at the bottom. The metal chips mixed in the warm water will be concentrated inside the cylindrical filter housing 27 at the bottom, and the warm water will be discharged into the water collecting housing 22 at the bottom.
