Description

Technical Field

[0001] This utility model relates to the field of honing rods, and in particular to a honing rod main structure with a spiral cooling channel. Background Technology

[0002] Honing is a high-precision internal hole machining method widely used in the automotive, aerospace and other fields. During the honing process, a large amount of heat is generated between the honing rod and the workpiece. If this heat is not dissipated in time, it will cause thermal deformation of the honing rod and the workpiece, affecting the machining accuracy and surface quality.

[0003] Traditional honing rod cooling systems mostly employ straight-through cooling channels, which have limited cooling effect and uneven coolant distribution, making it difficult to meet the requirements of high-precision honing. Therefore, a new cooling structure is needed to improve cooling efficiency and uniformity.

[0004] Therefore, it is necessary to propose a honing rod main body structure with a spiral cooling channel to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a honing rod main body structure with a spiral cooling channel, to solve the problem that traditional honing rod cooling systems mostly use straight-through cooling channels, which have limited cooling effect and uneven coolant distribution, making it difficult to meet the requirements of high-precision honing. Therefore, a new cooling structure is needed to improve cooling efficiency and uniformity.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a honing rod main body structure with a spiral cooling channel, comprising: a honing rod body;

[0007] A honing head, which is movably mounted on a honing rod and receives the honing force transmitted by the honing rod;

[0008] The honing head includes a connecting cylinder, a heat dissipation layer is provided on the outside of the connecting cylinder, and a fixing layer is provided on the outside of the heat dissipation layer;

[0009] The heat dissipation layer has spiral heat dissipation grooves along the height direction for coolant to pass through;

[0010] An oilstone is provided on the outer side of the fixed layer.

[0011] Preferably, the honing head is provided with a liquid inlet at the top and a liquid outlet at the bottom.

[0012] The liquid inlet and liquid outlet are connected to the top and bottom of the spiral heat dissipation groove, respectively.

[0013] Preferably, the connecting cylinder has an inner cavity, and the bottom end of the honing rod is connected to an extrusion head, which is extended and retracted within the inner cavity.

[0014] Telescopic rods are telescopically installed on both sides of the inner cavity. One end of the telescopic rod extends into the inner cavity, and the other end extends out of the outer side of the fixed layer. A connecting end is fixed to the extended end, and the oilstone is installed on the connecting end.

[0015] Preferably, a fixing block is installed at the bottom of the inner cavity, and a buffer pad for buffering the squeezing head is fixed at the top of the fixing block.

[0016] Preferably, the extrusion head is cone-shaped, with the tip of the cone facing downwards.

[0017] Preferably, multiple oilstones are provided, and the multiple oilstones are distributed at equal intervals around the outside of the fixing layer.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. The coolant enters the spiral heat dissipation groove through the inlet and flows away the heat generated during honing. The design of the spiral heat dissipation groove allows the coolant to flow evenly along the length of the honing rod body, carrying away more heat and significantly improving cooling efficiency. When the honing stone retracts, it can carry away the heat generated by the honing stone and also dissipate the frictional heat of the extrusion head inside the connecting cylinder. Furthermore, the gaps in the spiral heat dissipation groove can reduce the expansion rate generated when the metal is heated.

[0020] 2. The coolant is evenly distributed in the spiral channel, avoiding local overheating and improving the machining accuracy and surface quality of the honing rod and the workpiece. The spiral heat dissipation groove can be customized according to the specific size of the honing rod, which has good adaptability and flexibility. By effectively controlling the temperature during the honing process, the machining error caused by thermal deformation is reduced, and the machining efficiency and surface quality are improved.

[0025] This utility model provides, for example Figures 1-3 The honing rod body structure shown includes:

[0026] Honing rod 1;

[0027] The honing head is movably mounted on the honing rod 1 and receives the honing force transmitted by the honing rod 1.

[0028] The honing head includes a connecting cylinder 2, and a heat dissipation layer 3 is provided on the outside of the connecting cylinder 2 to conduct and dissipate the heat generated during the honing process.

[0029] To address the limitations of traditional honing rod cooling systems, which often employ straight-through cooling channels resulting in limited cooling efficiency and uneven coolant distribution, failing to meet the requirements of high-precision honing, a novel cooling structure is needed to improve cooling efficiency and uniformity. Therefore, a fixing layer 4 is installed outside the heat dissipation layer 3, and an oilstone 6 is extended and retracted outside the fixing layer 4. The fixing layer 4 increases the diameter of the honing head, enhancing structural stability and strength, and ensuring stable honing operation.

[0030] The connecting cylinder 2 has an inner cavity 12. The bottom end of the honing rod 1 is connected to the extrusion head 11. The extrusion head 11 is installed inside the inner cavity 12 with vertical extension. Telescopic rods 10 are installed on both sides of the inner cavity 12 with extension. One end of the telescopic rod 10 extends into the inner cavity 12, and the other end of the telescopic rod 10 extends out of the outer side of the fixing layer 4. The extended end is fixed with a connecting end 5. The oilstone 6 is installed on the connecting end 5.

[0031] The extrusion head 11 is set in a conical shape with the tip of the conical structure facing downward. It should be noted that the upper surface of the extension end of the telescopic rod 10 is provided with an inclined groove corresponding to the conical structure, so that when the extrusion head 11 moves downward, it can extrude the telescopic rod 10.

[0032] In the actual operation of this utility model, when the honing rod 1 drives the extrusion head 11 to move up and down reciprocally, the extrusion head 11 will squeeze the telescopic rod 10 to extend and retract outward, thereby driving the honing stone 6 to extend and retract, thus completing the honing work.

[0033] The heat dissipation layer 3 has a spiral heat dissipation groove 9 along the height direction for coolant to pass through. The top of the honing head is provided with a liquid inlet 7 and the bottom of the honing head is provided with a liquid outlet 8. The coolant enters the spiral heat dissipation groove 9 through the liquid inlet 7 and flows away the heat generated during honing. The design of the spiral heat dissipation groove 9 allows the coolant to flow evenly along the length of the honing rod body, carrying away more heat and significantly improving the cooling efficiency. When the honing stone 6 retracts, it can carry away the heat generated by the honing of the honing stone 6, and at the same time, it can also dissipate the frictional heat of the extrusion head 11 inside the connecting cylinder 2.

[0034] The coolant is evenly distributed in the spiral channel, avoiding local overheating and improving the machining accuracy and surface quality of the honing rod and the workpiece. The spiral heat dissipation groove 9 can be customized according to the specific size of the honing rod, which has good adaptability and flexibility. By effectively controlling the temperature during the honing process, the machining error caused by thermal deformation is reduced, and the machining efficiency and surface quality are improved.

[0035] The inlet 7 and outlet 8 are connected to the top and bottom of the spiral heat dissipation groove 9, respectively, and the outlet 8 is used to discharge the coolant.

[0036] A fixing block 13 is installed at the bottom of the inner cavity 12. A buffer pad 14 for buffering the extrusion head 11 is fixed at the top of the fixing block 13. Multiple oilstones 6 are provided, and the multiple oilstones 6 are distributed at equal distances around the outside of the fixing layer 4.
