Description

Technical Field

[0001] The present invention relates to the technical field of vehicle transmission shafts, and in particular to a transmission shaft fork processing system. Background Art

[0002] In the transmission system of an automobile, the drive shaft fork is an important component. The drive shaft fork is a component on the drive shaft used to connect, support or transmit power. It may appear in the form of a sliding fork, a lug fork, a universal joint fork, etc. When processing the drive shaft fork, due to its special shape, a general clamping device such as a vise cannot be used, and a special clamping device needs to be designed separately. In addition, in order to ensure the processing accuracy of the through holes at the two forks of the drive shaft fork during the processing, the design requirements for the positioning components on the clamping device are high. A common design is to place the part to be processed on a V-shaped pad on the base, use the inner positioning block for symmetry positioning, insert the inner hole on the inner positioning block on the positioning core shaft of the inner positioning block, use the inner positioning block to drive the spring support to form an upward thrust, and use the positioning core shaft to fix the nut for axial positioning.

[0003] In practice, however, the inner locating block is positioned on the top arc of the fork. The spring under the block is short and has a limited travel. As the inner gap of the blank increases, drilling can hit the inner locating block, weakening it and making it impossible to position the inner edge. Furthermore, when the part is placed into the mold, the two fork arcs contact the flat surface of the V-shaped pad for axial positioning. Without a lateral positioning surface, it easily tips over, rendering the part ineffective. Therefore, designing an effective clamping device is crucial. Summary of the Invention

[0029] The drive shaft yoke is a crucial component in a vehicle's transmission system. Due to its unique shape, its machining requires specialized fixtures. Conventional fixture designs struggle to maintain the yoke's positioning, and are prone to lateral or axial play or loosening, potentially leading to unexpected machining issues.

[0030] This embodiment discloses a transmission shaft fork processing system, such as Figure 1 and Figure 2 As shown, the fork assembly 01 may include a fixing assembly 01, a shaft fork assembly 02, and a processing assembly 03. The shaft fork assembly 02 may include a shaft fork body 21, a first fork portion 22, and a second fork portion 23. The first fork portion 22 may be fixedly connected to one end of the shaft fork body 21, and the second fork portion 23 may be fixedly connected to an end of the shaft fork body 21 away from the first fork portion 22. The first fork portion 22 and the second fork portion 23 may be spaced apart and disposed on the same central axis.

[0031] The fixing assembly 01 may include a supporting unit 11, a pad unit 12, a positioning unit 13 and an elastic unit 14. The supporting unit 11 may include a base 111, and a cavity with an open end is formed in the base 111. The pad unit 12 may include a first pad 121 and a second pad 122, and the first pad 121 and the second pad 122 are detachably connected to the two sides of the open end of the cavity of the base 111 respectively, and the detachable connection method may be a threaded locking connection or a snap-fit ​​connection. This connection method allows for quick replacement of parts, thereby improving work efficiency and reducing costs. Figure 5 As shown, the positioning unit 13 may include a positioning seat 131, a clamping module 132, an abutting module 133 and a positioning shaft 135. The clamping module 132 may include a first clamping portion 1321, which may be spaced apart at one end of the positioning seat 131, and the first clamping portion 1321 is fixedly connected to the positioning seat 131. The abutting module 133 may include a first abutting portion 1331 and a second abutting portion 1332, which may be fixedly connected to both ends of the positioning seat 131, respectively. Figure 3 and Figure 4 As shown, one end of the positioning shaft 135 can be slidably connected to the positioning seat 131, and the other end can be detachably connected to the base 111. The elastic unit 14 can be sleeved on the positioning shaft 135, and one end of the elastic unit 14 can be detachably connected to the positioning seat 131, and the other end can abut against the base 111.

[0032] like Figure 1 As shown, the machining assembly 03 may include a first tool 31, a second tool 32, and a drive unit 33. The drive unit 33 may be drivably connected to the first tool 31, and the drive unit 33 may be drivably connected to the second tool 32. When the drive unit 33 is in operation, both the first tool 31 and the second tool 32 start to operate to machine the part.

[0033] like Figure 1 and Figure 2As shown, the transmission shaft fork processing system can also include a processing state. The processing state can include one side of the first fork portion 22 and the second fork portion 23 abutting against the first pad 121, and the other side of the first fork portion 22 and the second fork portion 23 abutting against the second pad 122. The first pad 121 and the second pad 122 are placed obliquely on the base 111, respectively abutting against the curved surfaces of the first fork portion 22 and the second fork portion 23 to stably support the shaft fork assembly 02. In another embodiment, the abutting surfaces of the pad unit 12 and the shaft fork assembly 02 can be arc-shaped, so that the abutting surfaces have consistent shapes and the fit is more stable. The first clamping portion 1321 can abut against both sides of the first fork portion 22 or the second fork portion 23 to prevent the shaft fork assembly 02 from tipping toward the first pad 121 or the second pad 122 during processing, thereby making the clamping of the shaft fork assembly 02 more stable. The first abutment portion 1331 can abut against the end of the first fork 22 adjacent to the second fork 23, and the second abutment portion 1332 can abut against the end of the second fork 23 adjacent to the first fork 22, thereby limiting the sliding of the shaft fork assembly 02 along the processing direction of the first tool 31 or the second tool 32, avoiding the position deviation of the shaft fork assembly 02 during processing, and making the clamping of the shaft fork assembly 02 more stable. The elastic unit 14 can be compressed and deformed. According to the height of the matching groove between the shaft fork assembly 02 and the positioning unit 13, the positioning seat 131 can slide up and down along the axis on the positioning shaft 135 as the spring expands and contracts, so that the shaft fork assembly 02 is subjected to an upward thrust and is axially positioned. In another embodiment, the upper end of the shaft fork assembly 02 can have a pressure block that uses a cylinder to press the parts. The first tool 31 can move along the central axis of the first fork 22 toward the first fork 22, and the second tool 32 can move along the central axis of the second fork 23 toward the second fork 23. The first tool 31 and the second tool 32 can perform simultaneous machining. The distance between the contact points of two adjacent first clamping portions 1321 can be greater than the distance between the contact points of the first pad 121 and the second pad 122.

[0034] In some embodiments, as Figure 5 As shown, the clamping module 132 may further include a second clamping portion 1322. The second clamping portion 1322 may be spaced apart at one end of the positioning seat 131 away from the first clamping portion 1321. The second clamping portion 1322 may be fixedly connected to the positioning seat 131. The processing state may also include the second clamping portion 1322 abutting against both sides of the first fork portion 22 or the second fork portion 23. Therefore, in the processing state, the first clamping portion 1321 and the second clamping portion 1322 abut against both sides of the first fork portion 22 and the second fork portion 23, respectively, thereby avoiding an accident in which the shaft fork assembly 02 tips over toward the first pad 121 or the second pad 122 during processing, and making the clamping of the shaft fork assembly 02 more stable.

[0035] In some embodiments, as Figure 5As shown, the abutment module 133 may further include a third abutment portion 1333 and a fourth abutment portion 1334. The third abutment portion 1333 and the first abutment portion 1331 may be spaced apart at one end of the positioning seat 131, and the fourth abutment portion 1334 and the second abutment portion 1332 may be spaced apart at the other end of the positioning seat 131. The processing state may further include the third abutment portion 1333 abutting against the end of the first fork portion 22 adjacent to the second fork portion 23, and the fourth abutment portion 1334 abutting against the end of the second fork portion 23 adjacent to the first fork portion 22. In addition to the first abutment portion 1331 and the second abutment portion 1332, an abutment surface on the other side of the shaft fork assembly 02 is added, thereby limiting the sliding of the shaft fork assembly 02 along the processing direction of the first tool 31 or the second tool 32, avoiding the position deviation of the shaft fork assembly 02 during processing, and making the clamping of the shaft fork assembly 02 more stable.

[0036] In some embodiments, as Figure 6 and Figure 1 As shown, the cross-sectional area of ​​the abutment module 133 on the side closest to the shaft fork body 21 can gradually decrease toward the other side. The space between the first abutment portion 1331 and the third abutment portion 1333, and the space between the second abutment portion 1332 and the fourth abutment portion 1334, located on the same side of the positioning unit 13, are both increased. This can avoid the portions of the first and second cutting tools 31 and 32 that extend during processing, thereby preventing collisions that could damage the abutment module 133 or break the first and second cutting tools 31 and 32. In addition, the abutment surface between the abutment module 133 and the shaft fork body 21 is the portion with the largest cross-sectional area on the side closest to the shaft fork body 21, which is equivalent to extending the contact line between the abutment module 133 and the first and second fork portions 22 and 23, making the support of the shaft fork unit by the abutment module 133 more stable.

[0037] In some embodiments, as Figure 5 and Figure 1 As shown, the positioning unit 13 may further include an avoidance module 134. The avoidance module 134 may include a first avoidance portion 1341 and a second avoidance portion 1342. The first avoidance portion 1341 and the second avoidance portion 1342 may be respectively arranged at both ends of the positioning seat 131 to avoid the first tool 31 and the second tool 32 at both ends. The first avoidance portion 1341 and the second avoidance portion 1342 may be respectively recessed in the direction of approaching each other. The axial projection of the first tool 31 or the second tool 32 is within the recessed area of ​​the first avoidance portion 1341, and the axial projection of the first tool 31 or the second tool 32 is within the recessed area of ​​the second avoidance portion 1342. The recessed area can prevent the part of the tool extending during machining from contacting the positioning unit 13, causing damage to the abutment module 133 or breakage of the first tool 31 and the second tool 32.

[0038] In some embodiments, as Figure 1As shown, the supporting unit 11 may further include a chip removal module 112. The chip removal module 112 may include a first chip removal channel 1121, a second chip removal channel 1122, and a third chip removal channel 1123. One end of the first chip removal channel 1121 may be connected to the opening end of the cavity in the base 111, and the other end may be connected to the second chip removal channel 1122 and the third chip removal channel 1123, respectively. During machining, the shaft fork assembly 02 is located at the opening end of the cavity of the base 111, and the chips generated during machining may fall into the first chip removal channel 1121, and then be discharged into the connected second chip removal channel 1122 and the third chip removal channel 1123 through the first chip removal channel 1121. The end of the second chip removal channel 1122 away from the first chip removal channel 1121 may pass through the base 111 to communicate with the external space, and the second chip removal channel 1122 extends obliquely in a direction away from the opening end of the cavity in the base 111. The end of the third chip removal channel 1123 away from the first chip removal channel 1121 can pass through the base 111 and communicate with the external space. The third chip removal channel 1123 extends obliquely in a direction away from the cavity opening end within the base 111. Thus, chips generated during machining can be discharged into the second chip removal channel 1122 and the third chip removal channel 1123 and then discharged to the external space along the channels toward the cavity opening end of the base 111. The third chip removal channel 1123 and the second chip removal channel 1122 can be arranged symmetrically. The elastic unit 14 can be disposed in the first chip removal channel 1121.

[0039] In some embodiments, as Figure 1 and Figure 4 As shown, the support unit 11 may further include an axial hole 114, which may be connected to the first chip removal channel 1121. The end of the positioning shaft 135, distal from the positioning seat 131, may sequentially pass through the first chip removal channel 1121 and the elastic unit 14, extending into the axial hole 114 and forming an interference fit therewith. The cooperation between the axial hole 114 and the positioning shaft 135 allows the fixed assembly 01, including the support unit 11, the positioning unit 13, and the elastic unit 14, to be positioned properly, thereby enabling the normal clamping and processing of the shaft fork assembly 02.

[0040] In some embodiments, as Figure 1As shown, the supporting unit 11 may further include a mounting module 113. The mounting module 113 may include a first mounting groove 1131, a second mounting groove 1132 and a third mounting groove 1133. The first mounting groove 1131 and the second mounting groove 1132 may be respectively arranged on both sides of the opening end of the cavity in the base 111, the first mounting groove 1131 may be detachably connected to the first pad 121, and the second mounting groove 1132 may be detachably connected to the second pad 122. Through the first mounting groove 1131 and the second mounting groove 1132, the first pad 121 and the second pad 122 may be simply and conveniently positioned, and the detachable connection design facilitates the installation and replacement of the pad unit 12. The third mounting groove 1133 may be arranged at one end of the cavity in the base 111 away from the opening end, the third mounting groove 1133 is connected to the first chip removal channel 1121, and the elastic unit 14 abuts against the third mounting groove 1133. On the one hand, the third mounting groove 1133 provides support for the elastic unit 14 so that the elastic unit 14 can stably expand and contract. On the other hand, it expands the volume of the first chip removal channel 1121 to facilitate chip discharge.

[0041] In some embodiments, as Figure 5 and Figure 1 As shown, the positioning seat 131 can include a seat body 1311 and a sleeve body 1312. The clamping module 132 and the abutment module 133 can both be arranged on the seat body 1311. One end of the sleeve body 1312 can be fixedly connected to the seat body 1311, and the other end can extend toward the elastic unit 14. The extended end of the sleeve body 1312 is detachably connected to the elastic unit 14. When the shaft fork assembly 02 is installed, the elastic unit 14 can undergo elastic deformation to give the clamping module 132 an upward thrust, so that the clamping module 132 always clamps the shaft fork assembly 02. The sleeve body 1312 can be slidably connected to the positioning shaft 135, so that it slides up and down along the axis of the positioning shaft 135 as the elastic unit 14 expands and contracts. The outer contour dimensions of the sleeve body 1312 can match the outer contour dimensions of the first chip removal channel 1121 to enhance the stability of the sleeve body 1312 and prevent the sleeve body 1312 from shaking. The cross-sectional area of ​​the sleeve portion 1312 adjacent to its extended end can gradually decrease toward the extended end to form a chamfer. When multiple shaft fork assemblies 02 need to be processed and the next shaft fork assembly 02 is installed, the chamfered area can be combined with the compression deformation of the elastic unit 14 to squeeze downward to discharge chips accumulated in the first chip removal channel 1121 and the third installation groove 1133.

[0042] In some embodiments, as Figure 4 and Figure 1As shown, the pad unit 12 may further include a chip groove 123. The chip groove 123 may be provided on the first pad 121 and the second pad 122, respectively. The side of the first pad 121 close to the first chip channel 1121 may be recessed in a direction away from the first chip channel 1121 to form the chip groove 123, and the side of the second pad 122 close to the first chip channel 1121 may be recessed in a direction away from the first chip channel 1121 to form the chip groove 123. The notch of the chip groove 123 may be connected to the first chip channel 1121, and the chips generated during processing may fall into the chip groove 123 and be discharged through the first chip channel 1121 to the second chip channel 1122 or the third chip channel 1123 and then discharged to the external space.

[0043] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and that in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present disclosure.
