Description

Technical Field

[0001] The present invention relates to the technical field of inner spherical surface machining tools, in particular to an integrated differential housing machining tool and a machining method thereof. Background Art

[0002] The differential is a mechanism that enables the left and right (or front and rear) drive wheels to rotate at different speeds. It is mainly composed of left and right half-shaft gears, two planetary gears and a gear rack. The processing of the differential housing is particularly important. In the field of mechanical processing, the differential housing is a typical difficult-to-process part. Its processing accuracy and efficiency are crucial to the performance of the entire vehicle. The existing processing method usually adopts step-by-step processing, that is, first processing the spherical surface and then processing the end face. When processing the inner spherical surface of the differential housing, a gooseneck knife is often used for processing. The gooseneck knife is precisely designed and suitable for processing complex curved surfaces. It can ensure the processing accuracy of key parts such as the inner spherical surface of the differential housing. The gooseneck knife adopts multi-axis linkage processing and can process multiple areas of the inner spherical surface of the differential.

[0003] During the machining of the differential case, the gooseneck knife enters the inner cavity through the hole on the right end face of the differential case, and then performs turning. During this process, the machine tool needs to perform three-axis linkage of X-axis, Z-axis and B-axis to ensure the stability and accuracy of the machining process. In the process of the gooseneck knife entering the inner spherical surface of the differential case, the machine tool parameters need to be strictly designed to avoid collision between the gooseneck knife and the hole in the differential case. However, in the actual machining process, the gooseneck knife can only machine the inner spherical surface of the differential case. When the end face needs to be machined, the gooseneck knife needs to be removed from the inside of the differential case first, and the "turning knife" suitable for end face machining needs to be replaced to process the end face. This machining method requires the machine tool to frequently change parameters due to tool changes, which not only increases machining costs, but also reduces machining efficiency. For this reason, we propose an integrated differential case machining tool and a machining method thereof. Summary of the Invention

[0006] The rotating unit includes an arc-shaped sealing plate frame installed inside the steel sleeve and sliding within the steel sleeve. A steel shaft body is also installed on one side of the arc-shaped sealing plate frame, wherein the arc-shaped sealing plate frame and the inner wall of the steel sleeve are provided with springs. A positioning shaft body is also symmetrically installed on the arc-shaped sealing plate frame. The inner wall of the steel sleeve is provided with a limiting groove body corresponding to the positioning shaft body one by one. Each of the limiting groove bodies includes a straight groove body, an arc-shaped groove body connected to the straight groove body, and a positioning groove body connected to the arc-shaped groove body.

[0007] Preferably, one end of the steel shaft passes through the end of the steel sleeve and extends to the outside thereof.

[0008] Preferably, a ball is installed at the end of the positioning shaft, and the end of the positioning shaft and the ball can slide within the limiting groove.

[0009] Preferably, the tool body, the steel frame and the steel sleeve are all provided with liquid outlets that are interconnected, and the liquid outlet in the tool body is connected to the second injection channel.

[0010] Preferably, when the coolant is not introduced into the injection channel 2, the positioning shaft on the arc-shaped sealing plate frame is located in the straight groove body. When the coolant is introduced into the injection channel 2, the positioning shaft and the ball at its end enter the arc-shaped groove body along the trajectory of the straight groove body, and finally move into the positioning groove body along the trajectory of the arc-shaped groove body.

[0011] Preferably, a steel slider is symmetrically installed on one end of the steel shaft located outside the steel sleeve, and a fixed sleeve is fixedly installed on the annular frame. The fixed sleeve is symmetrically provided with sliding grooves, and the steel slider slides in a limited position in the sliding grooves.

[0012] Preferably, the cutting part includes a fixed frame body fixedly mounted on the annular frame, and a steel plate frame is fixedly mounted on one side of the fixed frame body by bolts, and a cutting tool is also fixedly mounted on the steel plate frame, and a processing blade 2 is mounted on the cutting tool.

[0013] Preferably, shock-absorbing rubber is embedded between the fixed frame and the steel plate frame.

[0014] Preferably, the steel sleeve and the cutting tool are both equipped with liquid outlet sleeves, and the two liquid outlet sleeves are connected by a hose.

[0015] A method for machining an integrated differential housing machining tool comprises the following steps:

[0016] S1: The tool body enters the interior of the differential housing and adjusts its position, then processes the inner spherical surface of the differential housing. During the processing, coolant is injected into channel 1 to cool and lubricate the processing area of ​​the processing blade 1. After the inner spherical surface of the differential housing is processed, the inner end surface is processed;

[0017] S2: Coolant is injected into the second injection channel. The coolant enters the steel sleeve through the liquid outlet. The coolant flowing out of the liquid outlet acts on the arc-shaped sealing plate frame, causing the arc-shaped sealing plate frame to move within the steel sleeve. During the movement, the arc-shaped sealing plate frame compresses the spring in contact with it. The positioning shaft on the arc-shaped sealing plate frame and the ball bearing at its end enter the arc-shaped groove along the straight groove track. When moving along the track of the arc-shaped groove, the arc-shaped sealing plate frame will adjust its angle;

[0018] S3: The steel shaft on one side of the arc-shaped sealing plate frame drives the steel slider to apply force to the slide groove in the fixed sleeve, causing the fixed sleeve to drive the annular frame to rotate. The annular frame drives the cutting tool and the second processing blade on it to adjust the angle through the fixed frame. When the positioning shaft on the arc-shaped sealing plate frame is located at the end of the positioning groove, the second processing blade is parallel to the first processing blade, and then the inner end surface of the differential case is processed;

[0019] S4: After the inner end surface of the differential housing is machined, coolant is no longer introduced into the injection channel 2, i.e., the arc-shaped sealing plate frame performs a reset motion under the action of the spring, and the positioning shaft and the ball bearings at its end enter the arc-shaped groove along the positioning groove and finally enter the straight groove. During this process, the steel shaft exerts a force on the sliding groove in the fixed sleeve through the steel slider, causing the fixed sleeve to drive the annular frame to rotate in the opposite direction. As a result, under the action of the fixed frame, the steel plate frame drives the cutting tool and the second processing blade thereon to reset;

[0020] S5: The tool body leaves the differential housing.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention utilizes a cutting tool and a second machining blade to machine the inner end surface of the differential housing, and limits the positioning shaft and the ball bearing on the arc-shaped sealing plate frame through a limiting groove body, so that the arc-shaped sealing plate frame can adjust its angle during movement in the steel sleeve, thereby enabling the steel shaft and the steel slider on the arc-shaped sealing plate frame to apply force to the slide groove in the fixed sleeve, and then the annular frame drives the fixed frame body to adjust its angle, and utilizes the fixed frame body to enable the steel plate frame to drive the cutting tool and the second machining blade thereon to rotate, so that the second machining blade enters the differential housing to machine the inner end surface. The structural design of the present invention can effectively machine the inner end surface of the differential housing without the need for frequent changes of the tool, thereby achieving the purpose of improving work efficiency.

[0023] The present invention utilizes two injection channels to transport coolant, allowing the coolant to enter the interior of the steel sleeve through the liquid outlet, and utilizes the injection of coolant to adjust the position of the arc-shaped sealing plate frame within the steel sleeve. Thus, the present invention can effectively adjust the position of the arc-shaped sealing plate frame according to the injection condition of the coolant, thereby effectively changing the angle of the cutting tool according to the position adjustment of the arc-shaped sealing plate frame, thereby realizing the angle control of the cutting tool by utilizing the injection of coolant, so that the cutting tool utilizes the two processing blades to process the inner end surface of the differential housing.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1-10 The present invention provides a technical solution: an integrated differential housing machining tool. The present invention makes corresponding improvements to the technical problems in the background technology, and combines the attached Figure 2 As shown, it includes a tool body 1 that is designed as an integral unit and processes the differential housing 12 and the inner end face 121. The interior of the differential housing 12 includes an inner spherical surface and an inner end face 121. Since the differential housing 12 is a prior art component, the present invention does not describe it in detail. The end of the tool body 1 is designed in a gooseneck shape and is equipped with a processing blade 2. It is further explained that in the actual process, the tool body 1 with a gooseneck design at the end enters the inner spherical surface of the differential housing 12 through CNC programming control, that is, combined with the multi-axis linkage function of the machine tool, the tool body 1 enters the inner spherical surface of the differential housing 12. Since the tool body 1 (gooseneck knife) with a gooseneck design at the end enters the inner spherical surface of the differential housing 12 is a prior art, the present invention does not describe it in detail. Figure 1As shown, a slot 3 is further provided on the tool body 1, and a steel frame 4 is fixedly installed at the slot 3. The steel frame 4 is fixed in the slot 3 by bolts, and the steel frame 4 has an opening downwardly provided. A steel sleeve 5 is fixedly installed in the steel frame 4, and an annular frame 51 rotatably connected to the outer wall of the steel sleeve 5 is installed on the steel sleeve 5, and a cutting portion 6 is provided on the annular frame 51. The cutting portion 6 is used to process the inner end surface 121 of the differential housing 12. When the tool body 1 enters the differential housing 12 and processes the inner spherical surface, the cutting portion 6 is located in the steel frame 4.

[0037] Combined with attachment Figure 5 As shown, as a further limitation of the present invention, the cutting portion 6 includes a fixed frame 61 fixedly mounted on the annular frame 51, and a steel plate frame 62 is fixedly mounted on one side of the fixed frame 61 by bolts, wherein a shock-absorbing rubber 65 is embedded between the fixed frame 61 and the steel plate frame 62. During the processing, the vibration force generated will be absorbed by the shock-absorbing rubber 65, and a cutting tool 63 is also fixedly mounted on the steel plate frame 62, and a processing blade 2 64 is installed on the cutting tool 63. A liquid outlet sleeve 11 is fixedly mounted on both the steel sleeve 5 and the cutting tool 63, and a communication channel is formed between the two liquid outlet sleeves 11. It is connected by a hose 111, and the hose 111 is adapted to the following angle adjustment, wherein one end of the tool body 1 is further provided with an injection channel 1 7 and an injection channel 2 8 for conveying coolant, the injection channel 1 7 is used to convey the coolant to the processing blade 1 2, the tool body 1, the steel frame 4 and the steel sleeve 5 are all provided with liquid outlets 10 that are interconnected, and the liquid outlet 10 in the tool body 1 is connected to the injection channel 2 8, and a rotating unit 9 for controlling the rotation of the annular frame 51 is provided in the steel sleeve 5, and the rotating unit 9 controls the angle adjustment of the annular frame 51 by injecting the coolant in the channel 2 8.

[0038] Furthermore, the present invention improves the technical problems in the background technology. The tool body 1 with a gooseneck end enters the differential housing 12 under the action of the machine tool. During this process, the cutting tool 63 and the processing blade 2 64 at the end are located in the steel frame 4. At this time, the cutting tool 63 will not affect the tool body 1 from entering the differential housing 12. Then the tool body 1 and the processing blade 1 2 at its end process the spherical surface inside the differential housing 12. During the processing, the coolant is transported to the processing blade 1 2 by using the injection channel 1 7 to play a cooling and lubricating role. When the inner After the spherical surface processing is completed, the inner end surface 121 needs to be processed; the inner end surface 121 of the differential housing 12 is located at both ends of the hole, and then the two inner end surfaces 121 of the differential housing 12 need to be processed, wherein the tool body 1 can process the end surface farther from the entry port, while the end surface closer to the entry port cannot be processed. It should be noted that the "entry port" refers to the hole in the differential housing 12 where the tool body 1 enters. The reason why the end surface closer to the entry port cannot be processed is mainly: since the end of the tool body 1 is gooseneck-shaped and has a certain curvature, when the tool body 1 When processing the end face closer to the entrance, the gooseneck-shaped tool body 1 will collide with the inner wall of the differential housing 12 (entrance). In the present invention, a cutting tool 63 and a processing blade 2 64 at its end are used to process the inner end face 121 of the differential housing 12. When processing is required, coolant is injected into the injection channel 2 8, and the coolant is used to control the rotation unit 9 to adjust the angle of the annular frame 51. That is, in the present invention, the angle adjustment value of the annular frame 51 is 90°, and the annular frame 51 drives the cutting tool through the fixed frame 61 and the steel plate frame 62. 63 and the processing blade 2 64 at its end are synchronously adjusted in angle. After the angle adjustment is completed, the tool body 1 can be controlled by the machine tool to perform directional movement. In actual use, it can be designed accordingly according to the size of the differential housing 12, so that the processing blade 1 2 and the processing blade 2 64 can simultaneously process the two inner end faces 121. If the processing blade 1 2 and the processing blade 2 64 cannot be processed at the same time when processing part of the inner end face 121 of the differential housing 12, the processing blade 1 2 and the processing blade 2 64 can be controlled by the machine tool to process the two inner end faces 121 respectively.

[0039] As a further limitation of the present invention, the rotating unit 9 includes an arc-shaped sealing plate frame 91 installed inside the steel sleeve 5 and sliding within it. A steel shaft 92 is also installed on one side of the arc-shaped sealing plate frame 91, and one end of the steel shaft 92 passes through the end of the steel sleeve 5 and extends to the outside thereof, wherein the arc-shaped sealing plate frame 91 and the inner wall of the steel sleeve 5 are provided with a spring 93, and the end of the spring 93 is in contact with the arc-shaped sealing plate frame 91. A positioning shaft 94 is also symmetrically installed on the arc-shaped sealing plate frame 91, and a ball 95 is installed at the end of the positioning shaft 94. The inner wall of the sleeve 5 is provided with a limiting groove 96 corresponding to the positioning shaft 94. The end of the positioning shaft 94 and the ball 95 can slide in the limiting groove 96. Each limiting groove 96 includes a straight groove 961, an arc groove 962 connected to the straight groove 961, and a positioning groove 963 connected to the arc groove 962. When the coolant is not introduced into the injection channel 28, the positioning shaft 94 on the arc sealing plate frame 91 is located in the straight groove 961. When the coolant is introduced into the injection channel 28, the positioning shaft 94 and the ball 95 at its end are moved along the straight groove. The track of the groove body 961 enters the arc groove body 962, and finally moves to the positioning groove body 963 along the track of the arc groove body 962. When the positioning shaft body 94 on the arc sealing plate frame 91 is located in the straight groove body 961 and the arc groove body 962, the feed end of the liquid outlet sleeve 11 on the steel sleeve 5 will be blocked by the arc sealing plate frame 91. At this time, the coolant cannot enter the feed end of the liquid outlet sleeve. When the positioning shaft body 94 on the arc sealing plate frame 91 is located at the end of the positioning groove body 963, the feed end of the liquid outlet sleeve will not be blocked by the arc sealing plate frame 9 1 and is located on the flow trajectory of the coolant, and then the coolant will enter the liquid outlet sleeve 11 of the cutting tool 63 through the hose 111, and along the cooling channel built into the cutting tool 63 (not shown in the figure) to cool and lubricate the processing blade 2 64 during the processing. The steel shaft 92 is located at one end outside the steel sleeve 5 and is symmetrically mounted with a steel slider 97. A fixed sleeve 52 is fixedly mounted on the annular frame 51, and a slide groove 53 is symmetrically opened on the fixed sleeve 52, and the steel slider 97 slides within the slide groove 53 within a limited position.

[0040] Specifically, in actual use, the tool body 1 with a gooseneck-shaped end is inserted into the differential housing 12 under the action of the machine tool and adjusted to a position, and then the inner spherical surface of the differential housing 12 is processed. During the processing, the coolant is injected through the injection channel 17 to cool and lubricate the processing part of the processing blade 12. When the inner spherical surface of the differential housing 12 is processed and the inner end face 121 needs to be processed, the coolant is injected into the injection channel 28, and the coolant enters the steel sleeve through the liquid outlet 10. In the cylinder 5, since the liquid outlet sleeve 11 on the steel sleeve 5 is blocked by the arc-shaped sealing plate frame 91, the coolant flowing out of the liquid outlet 10 will act on the arc-shaped sealing plate frame 91, so that the arc-shaped sealing plate frame 91 moves in a limited manner in the steel sleeve 5. It should be noted that the surface of the arc-shaped sealing plate frame 91 is smoothed to reduce the friction between the arc-shaped sealing plate frame 91 and the inner wall of the steel sleeve 5. The arc-shaped sealing plate frame 91 compresses the spring 93 in contact with it during the movement, and the coolant is passed through the arc-shaped sealing plate frame 91. The arc-shaped sealing plate frame 91 is continuously input into the steel sleeve 5, and the arc-shaped sealing plate frame 91 performs a limited movement in the steel sleeve 5, that is, the positioning shaft 94 on the arc-shaped sealing plate frame 91 and the ball 95 at its end enter the arc-shaped groove 962 along the track of the straight groove 961. When moving along the track of the arc-shaped groove 962, the arc-shaped sealing plate frame 91 will adjust the angle. In the invention, the angle adjustment value of the arc-shaped sealing plate frame 91 is 90°. During the angle adjustment process, one side of the arc-shaped sealing plate frame 91 The steel shaft 92 will move synchronously with it, that is, the steel slider 97 on the steel shaft 92 will exert a force on the slide groove 53 in the fixed sleeve 52, so that the fixed sleeve 52 drives the annular frame 51 to rotate, so that the annular frame 51 drives the steel plate frame 62 to drive the cutting tool 63 and the processing blade 64 thereon through the fixed frame 61 to adjust the angle. When the positioning shaft 94 on the arc-shaped sealing plate frame 91 is located at the end of the positioning groove 963, the cutting tool 63 is as shown in the attached Figure 4As shown, the feed end of the liquid outlet sleeve will not be blocked by the arc-shaped sealing plate frame 91, that is, it is located on the flow trajectory of the coolant, and then the coolant will enter the liquid outlet sleeve 11 of the cutting tool 63 through the hose 111, and along the cooling channel built into the cutting tool 63 (not shown in the figure) to cool and lubricate the processing blade 2 64 during the processing. When the inner end face 121 of the differential housing 12 is processed, it is necessary to ensure that the output pressure of the coolant is constant to avoid the output pressure floating. Then, under the structural design of the present invention, the inner end face 121 of the differential housing 12 can be effectively processed without frequent changes of the tool, and the machine tool only needs to adjust the parameters according to the size of the differential housing 12. That is, in order to achieve the purpose of improving work efficiency, when the inner end surface 121 of the differential housing 12 is processed, the injection channel 8 no longer flows into the coolant, that is, the arc-shaped sealing plate frame 91 performs a reset movement under the action of the spring 93, that is, the positioning shaft 94 and the ball 95 at its end will enter the arc-shaped groove 962 along the positioning groove 963 and finally enter the straight groove 961. During this process, the steel shaft 92 applies a force to the slide groove 53 in the fixed sleeve 52 through the steel slider 97, so that the fixed sleeve 52 drives the annular frame 51 to rotate in the opposite direction, so that under the action of the fixed frame 61, the steel plate frame 62 drives the cutting tool 63 and the processing blade 2 64 thereon to reset, that is, as shown in the attached figure. Figure 3 As shown, the tool body 1 can be removed from the differential housing 12 under the action of the machine tool.

[0041] A method for machining an integrated differential housing machining tool comprises the following steps:

[0042] S1: The tool body 1 enters the interior of the differential housing 12 and adjusts its position, then processes the inner spherical surface of the differential housing 12. During the processing, coolant is injected through the channel 17 to cool and lubricate the processing area of ​​the processing blade 12. After the inner spherical surface of the differential housing 12 is processed, the inner end surface 121 is processed;

[0043] S2: Coolant is injected into the second injection channel 8. The coolant enters the steel sleeve 5 through the liquid outlet 10. The coolant flowing out of the liquid outlet 10 acts on the arc-shaped sealing plate frame 91, causing the arc-shaped sealing plate frame 91 to move within the steel sleeve 5. During the movement, the arc-shaped sealing plate frame 91 compresses the spring 93 in contact with it. The positioning shaft 94 on the arc-shaped sealing plate frame 91 and the ball 95 at its end enter the arc-shaped groove 962 along the trajectory of the straight groove 961. When moving along the trajectory of the arc-shaped groove 962, the arc-shaped sealing plate frame 91 will adjust its angle.

[0044] S3: The steel shaft 92 on one side of the arc-shaped sealing plate frame 91 drives the steel slider 97 to apply force to the slide groove 53 in the fixed sleeve 52, so that the fixed sleeve 52 drives the annular frame 51 to rotate. The annular frame 51 drives the steel plate frame 62 to drive the cutting tool 63 and the second processing blade 64 thereon to adjust the angle through the fixed frame 61. When the positioning shaft 94 on the arc-shaped sealing plate frame 91 is located at the end of the positioning groove 963, the second processing blade is parallel to the first processing blade, and then the inner end surface 121 of the differential case 12 is processed;

[0045] S4: After the inner end surface 121 of the differential housing 12 is machined, the coolant is no longer introduced into the injection channel 8. That is, the arcuate sealing plate frame 91 is reset under the action of the spring 93. The positioning shaft 94 and the ball 95 at its end enter the arcuate groove 962 along the positioning groove 963 and finally enter the straight groove 961. During this process, the steel shaft 92 applies a force to the slide groove 53 in the fixed sleeve 52 through the steel slider 97, so that the fixed sleeve 52 drives the annular frame 51 to rotate in the opposite direction. As a result, under the action of the fixed frame 61, the steel plate frame 62 drives the cutting tool 63 and the second processing blade 64 thereon to reset.

[0046] S5 : The tool body 1 moves away from the differential case 12 .
