[0048] Machine body, feeding table, storage table and receiving box

[0049] This embodiment provides a motor shaft knurling device, comprising: a body 1, on which a knurling wheel set 2 is provided;

[0050] The machine also includes: a feeding table 3, which is arranged on the machine body 1 and located on one side of the knurling wheel group 2, and the top surface of the feeding table 3 is inclined; a blocking block group 4, which is arranged on the lower side of the top surface of the feeding table 3; a storage table 5, which is arranged on the left side of the feeding table 3, and the storage table 5 can sequentially transport materials to the feeding table 3; a material receiving box 6, which is arranged on the right side of the feeding table 3, and the material receiving box 6 is used to store knurled materials; a pushing piece 7, which has two pushing pieces and is respectively arranged on the front side of the feeding table 3 and the rear side of the knurling wheel group 2;

[0051] A V-shaped material trough is formed between the material blocking block group 4 and the top surface of the feeding platform 3 , and the material blocking block group 4 can be rotated to release the material trough.

[0052] The material storage platform 5 further includes: a lifting cylinder 19, which is arranged on the left side of the feeding platform 3, and a lifting platform 20 is arranged on the driving end of the lifting cylinder 19;

[0053] The lifting platform 20 is located between the material storage platform 5 and the material feeding platform 3 , and the lifting platform 20 can transport the materials on the material storage platform 5 to the material feeding platform 3 in sequence.

[0054] The machine body 1 is a machine body 1 of conventional structure. The top surface of the feeding platform 3 is inclined toward the direction of the receiving box 6. The blocking block group 4 is composed of a plurality of blocking block groups 4. The left surface of the blocking block is an inclined surface, and its inclination direction is opposite to that of the top surface of the feeding platform 3. A plurality of blocking blocks are evenly distributed along the front and rear directions of the feeding platform 3. A groove for the blocking block to move is provided on the top surface of the feeding platform 3. A plurality of blocking blocks are connected to each other by a rotating shaft, and the rotating shaft can be driven to rotate by a conventional rotating motor, thereby driving the blocking block group 4 to rotate. As the blocking block rotates, one side surface of the blocking block can be completely the same as the inclination of the top surface of the feeding platform 3 and parallel to the top surface of the feeding platform 3. The storage platform 5 is also inclined. The platform 5 is fixedly mounted on the machine body 1, and the inclination direction of the material storage platform 5 is toward the feeding platform 3. The lower side of the material storage platform 5 is lower than the high side of the feeding platform 3. There is a gap between the material storage platform 5 and the feeding platform 3, and the lifting platform 20 is located in the gap. The lifting platform 20 has a downwardly extending baffle on the side close to the material storage platform 5. The driving end of the lifting cylinder 19 is vertically upward and connected to the bottom of the lifting platform 20. A material blocking rod can also be installed on the material storage platform 5 along the front and rear directions. The gap between the material blocking rod and the surface of the material storage platform 5 can allow a motor shaft to pass through. The pushing piece 7 is a conventional pushing cylinder, and a turntable can also be installed at the end of the driving end of the pushing piece 7, so that the motor shaft is clamped by the two pushing pieces 7.

[0055] When the motor shaft is knurled, the motor shaft is stored on the storage table 5, and the motor shaft on the storage table 5 is transported to the feeding table 3 in turn. After the motor shaft is transported to the feeding table 3, the pushing piece 7 on the front side of the feeding table 3 pushes the motor shaft to the knurling wheel group 2 for knurling. After the knurling is completed, the pushing piece 7 on the rear side of the knurling wheel group 2 pushes the motor shaft back to the feeding table 3, and then the blocking block group 4 rotates to release the material trough, and the motor shaft falls into the receiving box 6 along the inclined top surface of the feeding table 3. Compared with the prior art, the utility model does not require workers to hold the shaft for loading and unloading, which effectively improves work efficiency.

[0056] Lubrication and cooling

[0057] The present embodiment also includes a lubricant spraying device 8, which is arranged above the knurling wheel group 2; a lubricant collecting tank 9, which is arranged in the machine body 1 and below the knurling wheel group 2; and a recovery pipe 10, which is arranged in the machine body 1.

[0058] The lubricating coolant spraying device 8 and the lubricating coolant collecting tank 9 are connected to each other through a recovery pipe 10 .

[0059] The recovery pipe 10 further includes: an outer pipe 11, which is connected to the lubricating coolant collection tank 9; an inner pipe 12, which is arranged in the outer pipe 11, and a plurality of liquid inlets 13 are evenly distributed on the surface of the inner pipe 12, and the inner pipe 12 is connected to the lubricating coolant spraying device 8; a filter belt 14, which is arranged in the inner pipe 12, and the filter belt 14 extends along the length direction of the inner pipe 12, and the filter belt 14 is radially arranged around;

[0060] The inner diameter of the liquid inlet 13 gradually decreases from the outside to the inside.

[0061] The lubricating coolant spraying device 8 is an existing conventional structure. The spraying head of the lubricating coolant spraying device 8 extends downward to the top of the knurled wheel group 2. The lubricating coolant spraying device 8 is connected to the inner tube 12 of the recovery tube 10 through a reflux pipe. A cavity for installing the recovery tube 10 is opened in the body 1. A movable door is installed on the side wall on the left side of the body 1. The left ends of the inner tube 12 and the outer tube 11 are both provided with detachable sealing covers, and the left end of the filter belt 14 is connected to the sealing cover.

[0062] During the knurling process of the motor shaft, the lubricating coolant spraying device 8 sprays the lubricating coolant on the knurling processing area, thereby effectively reducing the temperature of the motor shaft during knurling, preventing the motor shaft from being deformed, and improving the quality of the finished product of the motor shaft. The excess lubricating coolant can fall downward into the lubricating coolant collecting pool 9. The lubricating coolant in the lubricating coolant collecting pool 9 enters the outer tube 11 of the recovery pipe 10 during recovery, and then enters the inner tube 12 through a plurality of liquid inlets 13. Since the inner diameter of the liquid inlet 13 gradually decreases, the flow rate of the lubricating coolant when entering can be increased, and it is filtered on the filter belt 14. The filter belt 14 is radially arranged around to increase the contact area between the lubricating coolant and the filter belt 14, thereby increasing the filtering effect. When the lubricating coolant enters the inner tube 12 through a plurality of liquid inlets 13, turbulence can be generated, which increases the filtering stroke of the lubricating coolant, thereby further improving the filtering effect of the lubricating coolant, and then improving the recovery effect of the lubricating coolant, effectively recycling and reducing production costs.

[0063] Air Cooling

[0064] The present embodiment also includes: a fan housing 15, the fan housing 15 is arranged above the knurled wheel assembly 2, and an air inlet is arranged on the top of the fan housing 15; an air duct 16, the air duct 16 is arranged in the fan housing 15; a turbine fan 17, the turbine fan 17 is arranged in the fan housing 15; an air outlet slot 18, the air outlet slot 18 is arranged at the bottom of the fan housing 15 and communicates with the air duct 16;

[0065] The air inlet end of the turbo fan 17 is connected to the air inlet, the air outlet end of the turbo fan 17 is connected to the air duct 16 , and there are a plurality of air outlet slots 18 evenly distributed at the bottom of the fan housing 15 .

[0066] During the knurling process of the motor shaft, the operation of the turbine fan 17 drives the air flow into the air duct 16 of the fan housing 15. After entering the air duct 16, the air flow flows along the air duct 16 and finally flows toward the knurling wheel group 2 through the air outlet slot 18. The setting of the air outlet slot 18 can effectively increase the ejection speed of the air flow, thereby increasing the air flow velocity in the knurling wheel group 2 area, and quickly taking away the heat generated during the knurling process of the motor shaft. At the same time, the air flow can also be compressed in the process of flowing through the air outlet slot 18, thereby reducing the temperature of the air flow, further reducing the temperature of the motor shaft during the knurling process, and preventing the motor shaft from deformation.

[0067] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
