Description

Technical Field

[0001] This utility model relates to the field of static pressure guide sleeve technology for gear hobbing machines, specifically a static pressure guide sleeve device for gear hobbing machines. Background Technology

[0002] Currently, most gear shaper machines, both domestically and internationally, have mechanical tool holders. These typically use wear-resistant tin bronze guide sleeves, with the outer diameter of the tool shaft for positioning and the inserts for guidance, enabling the indexing movement of the gear shaper tool. In actual production, the clearance between the guide sleeve and the tool shaft is extremely critical. Excessive clearance can cause instability in the tool shaft's rotation, affecting machining accuracy. Insufficient clearance prevents lubricating oil from entering the guide sleeve, leading to tool shaft overheating and deformation, impacting the overall structural stability. Under current processing conditions, stable production is difficult to achieve, resulting in high scrap rates and incalculable economic losses. Furthermore, machining the tool shaft inserts is also challenging, requiring constant scraping to adjust the clearance with the guide sleeve, which is time-consuming and difficult to repair after wear. To improve the efficiency of gear shaper machines, a hydrostatic guide sleeve is needed. However, existing hydrostatic guide sleeves for gear shaper machines still have the following shortcomings:

[0003] When using existing hydrostatic guide sleeves for gear shapers, the stability of the use of these sleeves is easily affected because most of them are dependent on the processing equipment and the gap between the guide sleeve and the cutter shaft is not easy to adjust. This increases production costs and reduces economic benefits, resulting in a decrease in the practicality and efficiency of the hydrostatic guide sleeves for gear shapers.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a static pressure guide sleeve device for gear hobbing machines. Utility Model Content

[0005] The purpose of this utility model is to provide a hydrostatic guide sleeve device for a gear hobbing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydrostatic guide sleeve device for a gear hobbing machine, comprising a hydrostatic spline guide rail body, an injection-molded hydrostatic cavity body, and a hydrostatic guide sleeve body. The hydrostatic spline guide rail body has a limiting mounting groove inside, and a limiting mounting block is connected inside the limiting mounting groove. The injection-molded hydrostatic cavity body is located outside the limiting mounting block. Simultaneously, an oil cavity mounting groove is provided inside the injection-molded hydrostatic cavity body. An oil cavity through hole is provided at the middle of the oil cavity mounting groove, and an oil cavity block is provided inside the oil cavity mounting groove. The hydrostatic guide sleeve body is connected outside the injection-molded hydrostatic cavity body, and an injection through hole is provided inside the hydrostatic guide sleeve body.

[0007] Furthermore, the internal dimensions of the limiting mounting groove are adapted to the external dimensions of the limiting mounting block, and the limiting mounting block is slidably connected to the static pressure spline guide rail body through the limiting mounting groove.

[0008] Furthermore, the internal dimensions of the injection molding static pressure cavity body are adapted to the external dimensions of the static pressure spline guide rail body, and the outer side of the static pressure spline guide rail body is tightly fitted to the inner wall of the injection molding static pressure cavity body.

[0009] Furthermore, the internal dimensions of the oil cavity mounting groove are adapted to the external dimensions of the oil cavity block, and the oil cavity block is connected to the injection molding static pressure cavity body through the oil cavity mounting groove.

[0010] Furthermore, the number of oil chamber blocks is set to eight, and the eight oil chamber blocks are symmetrically arranged on both sides of the outside of the hydrostatic spline guide body with respect to the side center axis of the hydrostatic spline guide body.

[0011] Furthermore, the external dimensions of the injection molding static pressure cavity body are adapted to the internal dimensions of the static pressure guide sleeve body, and the outer side of the injection molding static pressure cavity body is tightly fitted to the inner side of the static pressure guide sleeve body.

[0012] Furthermore, the number of injection holes is set to eight, and the eight injection holes are equidistantly distributed inside the hydrostatic guide sleeve body.

[0013] Furthermore, the outer side of the injection through hole and the outer side of the oil cavity through hole are horizontally distributed, and the injection through hole and the oil cavity through hole are on the same horizontal plane.

[0014] This utility model provides a hydrostatic guide sleeve device for a gear hobbing machine, which has the following advantages:

[0015] 1. This utility model, through the setting of the injection-molded hydrostatic cavity body, enables the production of eight oil cavity blocks according to the size of the oil cavity mounting groove when the hydrostatic guide sleeve device of the gear hobbing machine is used. The eight oil cavity blocks are then evenly glued to the outside of the hydrostatic spline guide body by adhesive bonding. The hydrostatic guide sleeve body, together with the oil cavity blocks, is slidably installed on the outside of the hydrostatic spline guide body, thereby quickly completing the positioning of the hydrostatic guide sleeve body on the outside of the hydrostatic spline guide body and improving the overall processing efficiency of the subsequent hydrostatic guide sleeve.

[0016] 2. This utility model, through the design of the hydrostatic guide sleeve body, allows for the injection of a mixed liquid into the space between the hydrostatic guide sleeve body and the hydrostatic spline guide rail body via an injection through-hole inside the hydrostatic guide sleeve body during the use of the gear shaping machine hydrostatic guide sleeve device. This forms an injection-molded hydrostatic cavity body. The pre-set oil cavity block creates an oil cavity mounting groove inside the injection-molded hydrostatic cavity body, with an oil cavity through-hole located at the center of the groove. The prepared injection-molded hydrostatic cavity body makes the subsequent use of the hydrostatic guide sleeve body more stable, thereby reducing processing difficulty, increasing machine tool processing efficiency, and further improving the overall practicality and efficiency of the gear shaping machine hydrostatic guide sleeve.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1 to 4As shown, a hydrostatic guide sleeve device for a gear hobbing machine includes a hydrostatic spline guide rail body 1, an injection-molded hydrostatic cavity body 4, and a hydrostatic guide sleeve body 8. The hydrostatic spline guide rail body 1 has a limiting mounting groove 2 inside, and a limiting mounting block 3 is connected inside the limiting mounting groove 2. The injection-molded hydrostatic cavity body 4 is disposed outside the limiting mounting block 3. The internal dimensions of the limiting mounting groove 2 are adapted to the external dimensions of the limiting mounting block 3, and the limiting mounting block 3 is slidably connected to the hydrostatic spline guide rail body 1 through the limiting mounting groove 2. The internal dimensions of the injection-molded hydrostatic cavity body 4 are adapted to the external dimensions of the hydrostatic guide sleeve body 8. The external dimensions of the spline guide rail body 1 are adapted to the static pressure spline guide rail body 1, and the outer side of the static pressure guide rail body 1 is tightly fitted to the inner wall of the injection-molded static pressure cavity body 4. Eight oil cavity blocks 7 are made according to the dimensions of the oil cavity mounting groove 5, and the eight oil cavity blocks 7 are evenly pasted on the outside of the static pressure spline guide rail body 1 by adhesive bonding. The static pressure guide sleeve body 8 is slidably installed on the outside of the static pressure spline guide rail body 1 in conjunction with the oil cavity blocks 7, thereby quickly completing the positioning of the static pressure guide sleeve body 8 on the outside of the static pressure spline guide rail body 1 and improving the overall processing efficiency of the subsequent static pressure guide sleeve.

[0024] like Figures 1 to 4 As shown, the injection molding static pressure cavity body 4 has an oil cavity mounting groove 5 inside, and an oil cavity through hole 6 is opened in the middle of the oil cavity mounting groove 5. An oil cavity block 7 is installed inside the oil cavity mounting groove 5. A static pressure guide sleeve body 8 is connected to the outside of the injection molding static pressure cavity body 4. An injection through hole 9 is opened inside the static pressure guide sleeve body 8. The internal dimensions of the oil cavity mounting groove 5 are adapted to the external dimensions of the oil cavity block 7. The oil cavity block 7 is connected to the injection molding static pressure cavity body 4 through the oil cavity mounting groove 5. There are eight oil cavity blocks 7, which are symmetrically arranged on both sides of the static pressure spline guide rail body 1 along the side center axis. The external dimensions of the injection molding static pressure cavity body 4 are adapted to the internal dimensions of the static pressure guide sleeve body 8. The outer side of the injection molding static pressure cavity body 4 is tightly fitted to the inner side of the static pressure guide sleeve body 8. There are eight injection through holes 9, and each of the eight injection through holes is for injection. Through holes 9 are evenly distributed inside the hydrostatic guide sleeve body 8. The outer side of the injection through holes 9 and the outer side of the oil cavity through holes 6 are horizontally distributed, and the injection through holes 9 and the oil cavity through holes 6 are on the same horizontal plane. The wear-resistant coating and the curing agent are mixed in proportion and stirred evenly. The mixture is injected into the space between the hydrostatic guide sleeve body 8 and the hydrostatic spline guide rail body 1 through the injection through holes 9 inside the hydrostatic guide sleeve body 8, thereby forming the injection-molded hydrostatic cavity body 4. The oil cavity block 7 is set in advance so that the oil cavity mounting groove 5 is opened inside the injection-molded hydrostatic cavity body 4, and the oil cavity through hole 6 is opened in the middle of the oil cavity mounting groove 5. The injection-molded hydrostatic cavity body 4 makes the subsequent use of the hydrostatic guide sleeve body 8 more stable, thereby reducing the processing difficulty, increasing the processing efficiency of the machine tool, and further improving the overall practicality and efficiency of the gear shaping machine hydrostatic guide sleeve.

[0025] In summary, the hydrostatic guide sleeve device for this gear hobbing machine is used by first fabricating eight oil cavity blocks 7 to fit the dimensions of the oil cavity mounting groove 5. These eight blocks 7 are then evenly bonded to the outside of the hydrostatic spline guide rail body 1. The hydrostatic guide sleeve body 8, in conjunction with the oil cavity blocks 7, is then slidably installed on the outside of the hydrostatic spline guide rail body 1, thus quickly positioning the hydrostatic guide sleeve body 8 on the outside of the hydrostatic spline guide rail body 1. Next, the wear-resistant coating and curing agent are mixed in a specific ratio and stirred thoroughly. The mixture is then injected into the space between the hydrostatic guide sleeve body 8 and the hydrostatic spline guide rail body 1 through the injection port 9 inside the hydrostatic guide sleeve body 8, thereby forming an injection-molded hydrostatic cavity. The main body 4, through the pre-setting of the oil cavity block 7, allows the oil cavity mounting groove 5 to be opened inside the injection molding static pressure cavity main body 4, and an oil cavity through hole 6 is opened in the middle of the oil cavity mounting groove 5, which facilitates the use of the subsequent static pressure guide sleeve main body 8. The injection molding static pressure cavity main body 4 makes the use of the subsequent static pressure guide sleeve main body 8 more stable. At the same time, the limiting mounting block 3 formed by the injection molding static pressure cavity main body 4 during the manufacturing process can slide and connect with the limiting mounting groove 2 opened inside the subsequent gear hobbing machine, thereby improving the utilization efficiency of the static pressure guide sleeve, reducing the processing difficulty, increasing the processing efficiency of the machine tool, and further improving the overall practicality and utilization efficiency of the gear hobbing machine static pressure guide sleeve.
