Description

Technical Field

[0002] The secondary sun shaft baffle is a component installed at the end cover of the intermediate speed stage of the gearbox. It is generally made of metal and primarily serves to fix, seal, and support the gearbox during high-speed operation, as well as providing positioning and protection within the gearbox structure. Disassembling the secondary sun shaft baffle during gearbox maintenance is often quite cumbersome. Because the baffle dimensions are not entirely uniform, existing disassembly tools require operators to replace all components on the tooling according to the baffle's dimensions, resulting in high manufacturing and usage costs.

[0052] The disassembly fixture for the secondary sun shaft baffle of a gearbox disclosed in this application has the following advantages compared with the prior art:

[0053] The gearbox secondary sun shaft baffle disassembly fixture provided in this embodiment includes a clamping assembly, a first pull plate assembly, a first screw, a second pull plate assembly, and a second screw. The clamping assembly is detachably connected to the baffle.

[0071] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0072] like Figure 1 As shown in the embodiment of this application, a disassembly fixture for a gearbox secondary sun shaft baffle is proposed, comprising: a clamping assembly 1, a first pull plate assembly 2, a first screw 3, a second pull plate assembly 4, and a second screw 5; the clamping assembly 1 clamps the baffle circumferentially on the outside of the baffle, and the clamping assembly 1 is detachably connected to the baffle; the first pull plate assembly 2 is arranged radially on the outside of the clamping assembly 1; the first screw 3 is arranged parallel to the axial direction of the baffle, the first end of the first screw 3 is detachably connected to the clamping assembly 1, and the second end of the first screw 3 is slidably connected to the first pull plate assembly 2; the second pull plate assembly 4 is arranged radially on the side of the baffle opposite to the first pull plate assembly 2, and the second pull plate assembly 4 is perpendicular to the first pull plate assembly 2; the second screw 5 is arranged parallel to the axial direction of the baffle, the first end of the second screw 5 is detachably connected to the baffle, and the second end of the second screw 5 is slidably connected to the second pull plate assembly 4.

[0073] The disassembly fixture for the secondary sun shaft baffle of the gearbox provided in this embodiment includes a clamping assembly 1, a first pull plate assembly 2, a first screw 3, a second pull plate assembly 4, and a second screw 5. The clamping assembly 1 is detachably connected to the baffle. The first pull plate assembly 2 is detachably connected to the baffle via the first screw 3, and the second pull plate assembly 4 is detachably connected to the baffle via the second screw 5. When it is necessary to remove the baffle, the clamping assembly 1 is used to clamp the baffle, and then the fixture is assembled. The baffle can be removed from the sun shaft by pulling the first pull plate assembly 2 and the second pull plate assembly 4. The arrangement of the first pull plate assembly 2 and the second pull plate assembly 4 makes it easier for the operator to apply force, and the first pull plate assembly 2 and the second pull plate assembly 4 are vertically arranged. By simultaneously pulling the first pull plate assembly 2 and the second pull plate assembly 4, the uniformity of the force on the baffle is improved, and severe deformation of the baffle after being subjected to force is avoided. When it is necessary to remove baffles of different sizes, it is only necessary to separate the first screw 3 from the clamping assembly 1, slide and adjust the position of the first screw 3 on the first pull plate assembly 2 according to the baffle size, slide and adjust the position of the second screw 5 on the second pull plate assembly 4, and then reassemble the clamping assembly 1 and the first screw 3 that are adapted to the baffle. This allows the tooling to be adapted to baffles of different sizes. When removing baffles of different sizes, it is not necessary to replace all the parts on the tooling, reducing the manufacturing and use costs of the tooling and making the tooling more adaptable and practical.

[0074] Furthermore, the first screw 3 is perpendicular to the first pull plate assembly 2 and the clamping assembly 1. By pulling the first pull plate assembly 2, the first screw 3 applies a pulling force parallel to the baffle axis to the clamping assembly 1. The second screw 5 is perpendicular to the second pull plate assembly 4 and the baffle. By pulling the second pull plate assembly 4, the second screw 5 applies a pulling force parallel to the baffle axis to the baffle. This ensures that no radial force is generated when removing the baffle, making the removal of the baffle easier.

[0075] Furthermore, the second pull plate assembly 4 is perpendicular to the first pull plate assembly 2, which makes the baffle more evenly stressed when the tooling is pulled, thereby avoiding the problem of severe baffle deformation caused by uneven stress.

[0076] like Figure 2 As shown, in one feasible embodiment, the clamping assembly 1 includes: two clamping plates 11, two bolts 12, and two fasteners 13; the clamping plates 11 are arranged circumferentially along the baffle, the two clamping plates 11 surround a clamping cavity, the baffle is embedded in the clamping cavity, and the side wall of the baffle is in contact with the inner wall of the clamping plate 11; the bolts 12 pass through the two clamping plates 11 in sequence, and the two bolts 12 are respectively located at both ends of the clamping plate 11; the fasteners 13 are threadedly connected to the bolts 12, the fasteners 13 and bolts 12 correspond one-to-one, and the fasteners 13 are in contact with the outer wall of the clamping plate 11; wherein, there are two first screws 3, and the first screws 3 correspond one-to-one with the bolts 12.

[0077] In this technical solution, two clamping plates 11 surround and clamp the baffle from the circumference of the baffle to increase the contact friction between the clamping plates 11 and the baffle, thereby improving the stability of the clamping plates 11 installed on the baffle. A bolt 12 is provided at one end of each clamping plate 11. After the two clamping plates 11 are joined together and form a clamping cavity, they are positioned by the bolt 12 at the end. Then, the two clamping plates 11 are pressed and fixed by fasteners 13 threadedly connected to the bolts 12, thereby ensuring that the two clamping plates 11 apply sufficient clamping force to the baffle from the circumference of the baffle, and ensuring the structural stability and reliability of the clamping assembly 1 after it is connected to the baffle. The first screw 3 corresponds one-to-one with the bolt 12. The two first screws 3 apply tension to the two bolts 12 respectively. The tension is transmitted by the bolts 12, so that the tension can be evenly applied to the two clamping plates 11, improving the synchronicity of the movement of the two clamping plates 11, thereby preventing the two clamping plates 11 from being misaligned, and further ensuring the stability of the connection between the clamping assembly 1 and the baffle.

[0078] Furthermore, the two bolts 12 are positioned symmetrically on the clamping plate 11, which helps to improve the uniformity of the clamping force distribution of the clamping plate 11 on the baffle. By sliding and adjusting the first screw 3, the first screw 3 is made perpendicular to the bolt 12 and the first pull plate assembly 2, so that when the first pull plate assembly 2 is pulled, the pulling force is perpendicular to the clamping plate 11 and the baffle, preventing the baffle from being subjected to other directional forces, making removal easier. As a preferred embodiment, the plane where the axes of the two first screws 3 are located passes through the first radial line of the baffle.

[0079] like Figure 2 As shown, in one feasible embodiment, the clamp 11 includes: a contact portion 111 and two connecting portions 112; the contact portion 111 is arranged along the circumference of the baffle, and the side wall of the baffle is in contact with the inner wall of the contact portion 111; the connecting portions 112 are arranged perpendicular to the axis of the baffle, and the two connecting portions 112 are respectively arranged at both ends of the contact portion 111.

[0080] In this technical solution, the shape of the contact portion 111 is adapted to the baffle. A connecting portion 112 is provided at the end of the contact portion 111 to facilitate the installation of the bolt 12. By making the connecting portion 112 perpendicular to the axis of the baffle, the fastener 13 can be completely fitted with the connecting portion 112 after being screwed on, thereby ensuring that the pressure of the fastener 13 on the connecting portion 112 is perpendicular to the axis of the baffle, thus ensuring the stability of the fastener 13 pressing the clamping plate 11. Specifically, the radial cross-section of the baffle is circular, the inner wall of the contact portion 111 is arc-shaped, and the shape of the inner wall of the contact portion 111 is adapted to the shape of the outer wall of the baffle.

[0081] like Figure 1As shown, in one feasible embodiment, the disassembly fixture for the secondary sun shaft baffle of the gearbox further includes: a connecting ring 6 and a first nut 7; the connecting ring 6 is disposed at the first end of the first screw 3, the connecting ring 6 is fitted on the outside of the bolt 12, and the connecting ring 6 is located between the two clamping plates 11; the first nut 7 is fitted on the outside of the first screw 3, the first nut 7 is threadedly connected to the first screw 3, the first nut 7 is in contact with the side of the first pull plate assembly 2 away from the baffle, and the first nut 7 corresponds one-to-one with the first screw 3.

[0082] In this technical solution, the connecting ring 6 is fixed on the first screw 3, and the connecting ring 6 is detachably connected to the bolt 12. The connecting ring 6 is limited by two clamping plates 11. When the two clamping plates 11 are separated, the connecting ring 6 can be removed from the bolt 12, so that the first screw 3 is separated from the clamping assembly 1. The first nut 7 is threadedly connected to the first screw 3, and the first nut 7 is attached to the side of the first pull plate assembly 2 away from the baffle. When the first pull plate assembly 2 is pulled, the first nut 7 limits the first pull plate assembly 2, ensuring the synchronous movement of the first screw 3 and the first pull plate assembly 2, thereby applying a pulling force to the clamping assembly 1 through the first screw 3.

[0083] like Figure 1 As shown, in one feasible embodiment, the baffle is provided with two mounting screw holes, the first end of the second screw 5 is embedded in the mounting screw hole, and the second screw 5 is threadedly connected to the mounting screw hole; wherein, there are two second screws 5, and the second screw 5 corresponds one-to-one with the mounting screw hole; the disassembly tooling for the gearbox secondary sun shaft baffle also includes: a second nut 8; the second nut 8 is fitted on the outside of the second screw 5, the second nut 8 is threadedly connected to the second screw 5, the second nut 8 is in contact with the side of the second pull plate assembly 4 away from the baffle, and the second nut 8 corresponds one-to-one with the second screw 5.

[0084] In this technical solution, the second screw 5 is threadedly connected to the baffle through a mounting screw hole. When the second pull plate assembly 4 is pulled, the pulling force is directly applied to the baffle through the second screw 5, avoiding the leakage of force caused by relative sliding between the clamping assembly 1 and the baffle, thereby ensuring the removal efficiency of the baffle. The second nut 8 is threadedly connected to the second screw 5, and the second nut 8 is in contact with the side of the second pull plate assembly 4 away from the baffle. When the second pull plate assembly 4 is pulled, the second nut 8 limits the second pull plate assembly 4, ensuring the synchronous movement of the second screw 5 and the second pull plate assembly 4, thereby applying a pulling force to the baffle through the second screw 5.

[0085] Furthermore, the line connecting the centers of the two mounting screw holes passes through the second radial line of the baffle, and the second radial line is perpendicular to the first radial line. This improves the uniformity of the force on the baffle in the circumferential direction when removing the baffle. By sliding and adjusting the second screw 5, the second screw 5 is made perpendicular to the baffle and the second pull plate assembly 4, so that the pulling force when pulling the second pull plate assembly 4 is perpendicular to the baffle, preventing the baffle from being subjected to other directional forces, making removal easier.

[0086] It should be noted that the tooling can also be used to install the auxiliary baffle. When installing the baffle, a third nut needs to be added to the first screw 3 and positioned on the side of the first pull plate assembly 2 closest to the baffle; a fourth nut needs to be added to the second screw 5 and positioned on the side of the second pull plate assembly 4 closest to the baffle. By pushing the first pull plate assembly 2 and the second pull plate assembly 4 in the direction of the baffle, the third nut limits the first pull plate assembly 2 and the fourth nut limits the second pull plate assembly 4, so that the first pull plate assembly 2 abuts against the clamping assembly 1 and the second pull plate assembly 4 abuts against the baffle, the baffle can be installed on the sun shaft, further improving the practicality of the tooling.

[0087] like Figure 1 As shown, in one feasible embodiment, the disassembly fixture for the secondary sun shaft baffle of the gearbox further includes: a slide rod 9 and a limiting plate 10; the slide rod 9 is arranged along the axis of the baffle, the first end of the slide rod 9 is connected to the second pull plate assembly 4, the slide rod 9 passes through the first pull plate assembly 2, and the slide rod 9 is slidably connected to the first pull plate assembly 2; the limiting plate 10 is arranged on the slide rod 9, and the limiting plate 10 is located at the end of the slide rod 9 away from the baffle.

[0088] In this technical solution, the slide rod 9 is fixed on the second pull plate assembly 4, and the slide rod 9 passes through the first pull plate assembly 2. The first pull plate assembly 2 can slide relative to the slide rod 9. By setting a limiting plate 10 at the end of the slide rod 9 away from the baffle, the first pull plate assembly 2 is prevented from separating from the slide rod 9. When assembling the tooling, by making the first pull plate assembly 2 fit with the limiting plate 10 and the second pull plate assembly 4 fit with the first pull plate assembly 2, the first pull plate assembly 2 and the second pull plate assembly 4 can move synchronously when the operator pulls the second pull plate assembly 4. This allows the first screw 3 and the second screw 5 to pull and clamp the assembly 1 and the baffle simultaneously, improving the uniformity of force during the baffle removal process, helping to reduce the difficulty of removing the baffle, and improving the removal efficiency of the baffle.

[0089] Furthermore, the cross-section of the slide rod 9 is polygonal to prevent the second pull plate assembly 4 from rotating relative to the slide rod 9, thereby ensuring that the angle between the first pull plate assembly 2 and the second pull plate assembly 4 remains unchanged. As a preferred embodiment, the angle between the first pull plate assembly 2 and the second pull plate assembly 4 is 90 degrees.

[0090] like Figure 3As shown, in one feasible embodiment, the first pull plate assembly 2 further includes: a first plate body 21, two first guide grooves 22, two first connecting sleeves 23, two first adjusting hole assemblies 24, and two first mounting plate assemblies 25; the first plate body 21 is arranged radially along the baffle; the first guide grooves 22 are arranged at both ends of the first plate body 21 along the length direction of the first plate body 21; the first connecting sleeves 23 are embedded in the first guide grooves 22, the first connecting sleeves 23 are slidably connected to the first plate body 21, and the first connecting sleeves 23 correspond one-to-one with the first guide grooves 22; the first connecting sleeves 23 are fitted on the outside of the first screw 3, the first connecting sleeves 23 are slidably connected to the first screw 3, and... The first connecting sleeve 23 corresponds one-to-one with the first screw 3; the first adjusting hole assembly 24 includes a plurality of first adjusting holes, which are arranged on the first plate 21 along the length direction of the first plate 21, and the first adjusting hole assembly 24 corresponds one-to-one with the first guide groove 22; the first mounting plate assembly 25 is slidably connected to the outside of the first plate 21, and the first mounting plate assembly 25 covers the first adjusting hole assembly 24, and the first mounting plate assembly 25 corresponds one-to-one with the first adjusting hole assembly 24; after the first mounting plate assembly 25 passes through one of the first adjusting holes, the first mounting plate assembly 25 engages with the corresponding first connecting sleeve 23 to position the first connecting sleeve 23.

[0091] In this technical solution, there are two first screws 3. The number of first guide grooves 22, first connecting sleeves 23, first adjusting hole assemblies 24, and first mounting plate assemblies 25 are all consistent with the number of first screws 3. The first guide grooves 22 are disposed on the first plate 21, and the first connecting sleeves 23 slide within the first guide grooves 22 to limit and guide the sliding of the first connecting sleeves 23. The first screws 3 are slidably connected to the first connecting sleeves 23. By sliding the first connecting sleeves 23, the position of the first screws 3 in the length direction of the first plate 21 is adjusted, thereby ensuring... With the first screw 3 perpendicular to the first plate 21, the first screw 3 can be adapted to clamping components 1 of different sizes; the first mounting plate assembly 25 is slidably connected to the first plate 21, the first mounting plate assembly 25 passes through the first adjustment hole and is embedded in the first connecting sleeve 23. Through the cooperation between the first mounting plate assembly 25 and the first adjustment hole, the first connecting sleeve 23 is positioned, thereby fixing the position of the first screw 3 relative to the first plate 21. Based on the slidable connection between the first pull plate assembly 2 and the first screw 3, the stability of the connection between the first screw 3 and the first pull plate assembly 2 is improved.

[0092] like Figure 4As shown, in one feasible embodiment, the first mounting plate assembly 25 includes: a first mounting plate 251, a first insert rod 252, a first gripping plate 253, and a first elastic member 254; the first mounting plate 251 is disposed on the outer side of the first plate body 21, and the first mounting plate 251 is slidably connected to the first plate body 21; the first insert rod 252 passes through the first mounting plate 251 and one of the first adjustment holes in sequence, and then is embedded in the first connecting sleeve 23; the first gripping plate 253 is disposed at the end of the first insert rod 252 away from the first mounting plate 251, and the cross-sectional area of ​​the first gripping plate 253 is larger than the cross-sectional area of ​​the first insert rod 252; the first elastic member 254 is disposed between the first mounting plate 251 and the first gripping plate 253, the first end of the first elastic member 254 is connected to the first mounting plate 251, the second end of the first elastic member 254 is connected to the first gripping plate 253, and the first elastic member 254 provides tension to the first gripping plate 253.

[0093] In this technical solution, after the first insertion rod 252 passes through the first mounting plate 251 and the first adjustment hole in sequence, the first insertion rod 252 is embedded in the first connecting sleeve 23, so as to fix the position of the first connecting sleeve 23 on the first plate 21 by the first insertion rod 252, and then fix the position of the first screw 3 on the first plate 21 in the length direction by the first connecting sleeve 23; a first gripping plate 253 is fixedly connected to the first insertion rod 252, and the cross-sectional area of ​​the first gripping plate 253 is larger than the cross-sectional area of ​​the first insertion rod 252, thereby facilitating operation. The operator holds the first grip plate 253 to control the movement of the first insertion rod 252, which is convenient to use. By setting the first elastic element 254 between the first mounting plate 251 and the first grip plate 253, the first elastic element 254 provides a pulling force to the first grip plate 253 to elastically connect the first insertion rod 252 to the first mounting plate 251, thereby ensuring that the first insertion rod 252 is stably embedded in the first connecting sleeve 23, preventing the first insertion rod 252 from falling out of the first connecting sleeve 23, and ensuring that the first insertion rod 252 is effectively and reliably positioned in the first connecting sleeve 23.

[0094] As a preferred embodiment, the first elastic element 254 is a linear spring, and the first elastic element 254 is fitted onto the outside of the first insert 252.

[0095] like Figure 3As shown, in one feasible embodiment, the second pull plate assembly 4 further includes: a second plate body 41, two second guide grooves 42, two second connecting sleeves 43, two second adjusting hole assemblies 44, and two second mounting plate assemblies 45; the second plate body 41 is arranged radially along the baffle; the second guide grooves 42 are arranged at both ends of the second plate body 41 along the length direction of the second plate body 41; the second connecting sleeves 43 are embedded in the second guide grooves 42, the second connecting sleeves 43 are slidably connected to the second plate body 41, and the second connecting sleeves 43 correspond one-to-one with the second guide grooves 42; the second connecting sleeves 43 are fitted on the outside of the second screw 5, the second connecting sleeves 43 are slidably connected to the second screw 5, and... The second connecting sleeve 43 corresponds one-to-one with the second screw 5; the second adjusting hole assembly 44 includes a plurality of second adjusting holes, which are arranged on the second plate 41 along the length direction of the second plate 41, and the second adjusting hole assembly 44 corresponds one-to-one with the second guide groove 42; the second mounting plate assembly 45 is slidably connected to the outside of the second plate 41, and the second mounting plate assembly 45 covers the second adjusting hole assembly 44, and the second mounting plate assembly 45 corresponds one-to-one with the second adjusting hole assembly 44; after the second mounting plate assembly 45 passes through one of the second adjusting holes, the second mounting plate assembly 45 engages with the corresponding second connecting sleeve 43 to position the second connecting sleeve 43.

[0096] In this technical solution, there are two second screws 5. The number of second guide grooves 42, second connecting sleeves 43, second adjusting hole assemblies 44, and second mounting plate assemblies 45 are consistent with the number of second screws 5. The second guide grooves 42 are disposed on the second plate 41, and the second connecting sleeves 43 slide within the second guide grooves 42 to limit and guide the sliding of the second connecting sleeves 43. The second screws 5 are slidably connected to the second connecting sleeves 43. By sliding the second connecting sleeves 43, the position of the second screws 5 in the length direction of the second plate 41 is adjusted, thereby ensuring... With the second screw 5 perpendicular to the second plate 41, the second screw 5 can be adapted to clamping components 1 of different sizes; the second mounting plate assembly 45 is slidably connected to the second plate 41, the second mounting plate assembly 45 passes through the second adjustment hole and is embedded in the second connecting sleeve 43. Through the cooperation between the second mounting plate assembly 45 and the second adjustment hole, the second connecting sleeve 43 is positioned, thereby fixing the position of the second screw 5 relative to the second plate 41. Based on the slidable connection between the second pull plate assembly 4 and the second screw 5, the stability of the connection between the second screw 5 and the second pull plate assembly 4 is improved.

[0097] like Figure 5As shown, in one feasible embodiment, the second mounting plate assembly 45 includes: a second mounting plate 451, a second insert rod 452, a second gripping plate 453, and a second elastic member 454; the second mounting plate 451 is disposed on the outer side of the second plate body 41, and the second mounting plate 451 is slidably connected to the second plate body 41; the second insert rod 452 passes through the second mounting plate 451 and one of the second adjustment holes in sequence, and then is embedded in the second connecting sleeve 43; the second gripping plate 453 is disposed at the end of the second insert rod 452 away from the second mounting plate 451, and the cross-sectional area of ​​the second gripping plate 453 is larger than the cross-sectional area of ​​the second insert rod 452; the second elastic member 454 is disposed between the second mounting plate 451 and the second gripping plate 453, the second end of the second elastic member 454 is connected to the second mounting plate 451, and the second end of the second elastic member 454 is connected to the second gripping plate 453, and the second elastic member 454 provides tension to the second gripping plate 453.

[0098] In this technical solution, after the second insertion rod 452 passes through the second mounting plate 451 and the second adjustment hole in sequence, the second insertion rod 452 is embedded in the second connecting sleeve 43, so as to fix the position of the second connecting sleeve 43 on the second plate 41 through the second insertion rod 452, and then fix the position of the second screw 5 on the second plate 41 in the length direction through the second connecting sleeve 43; a second gripping plate 453 is fixedly connected to the second insertion rod 452, and the cross-sectional area of ​​the second gripping plate 453 is larger than the cross-sectional area of ​​the second insertion rod 452, thereby facilitating operation. The operator holds the second grip plate 453 to control the movement of the second insertion rod 452, which is convenient to use; by setting a second elastic element 454 between the second mounting plate 451 and the second grip plate 453, the second elastic element 454 provides a pulling force to the second grip plate 453 to elastically connect the second insertion rod 452 to the second mounting plate 451, thereby ensuring that the second insertion rod 452 is stably embedded in the second connecting sleeve 43, preventing the second insertion rod 452 from falling out of the second connecting sleeve 43, and ensuring that the second insertion rod 452 is effectively and reliably positioned in the second connecting sleeve 43.

[0099] As a preferred embodiment, the second elastic element 454 is a linear spring, and the second elastic element 454 is fitted onto the outside of the second insert 452.

[0100] Working principle:

[0101] When the operator needs to disassemble the secondary sun shaft baffle of the gearbox, the operator can first put the two clamping plates 11 on the outside of the baffle, then push the first screw 3 to drive the connecting ring 6 to move, move the connecting ring 6 between the two contact parts 111 at the same end of the clamping plate 11, then use the bolt 12 to pass through the contact parts 111 and the connecting ring 6, and install the fastener 13 on the bolt 12, thereby fixing the clamping assembly 1 on the baffle.

[0102] The operator moves the second screw 5 to the corresponding mounting screw hole on the baffle and screws the second screw 5 into the mounting screw hole; then, the operator screws the first nut 7 and the second nut 8 so that the first nut 7 abuts against the first connecting sleeve 23 and the second nut 8 abuts against the second connecting sleeve 43.

[0103] At this time, the operator pulls the first plate 21 away from the baffle. The first plate 21 drives the slide rod 9 and the second plate 41 to move through the limiting plate 10. The movement of the first plate 21 drives the first nut 7 to move through the first connecting sleeve 23. Then, through the cooperation of the first nut 7, the first screw 3 and the connecting ring 6, the bolt 12 is pulled, thereby driving the clamping plate 11 to move. Similarly, the movement of the second plate 41 drives the second nut 8 to move through the second connecting sleeve 43. The movement of the second nut 8 can drive the second screw 5 and the baffle to move, thereby removing the secondary sun shaft baffle of the gearbox.

[0104] When the dimensions of the gearbox secondary sun shaft baffle that needs to be removed change, the operator only needs to replace the clamping plate 11 that matches the baffle, and then pull the first gripping plate 253. The first gripping plate 253 drives the first insert rod 252 to move and stretches the first elastic member 254, thereby pulling the first insert rod 252 out of one of the first adjustment holes, releasing the positioning of the first mounting plate 251 and the first connecting sleeve 23. Then, move the first connecting sleeve 23 located in the first guide groove 22 and adjust the position of the first connecting sleeve 23. When the first connecting sleeve 23 moves to the designated position, release the first gripping plate 253, the first elastic member 254 retracts, and the first elastic member 254 pulls the first gripping plate 253 and the first insert rod 252 towards the first mounting plate 251 until the first insert rod 252 is inserted into the corresponding first adjustment hole, so as to simultaneously position the first mounting plate 251 and the first connecting sleeve 23. Similarly, the position of the second connecting sleeve 43 in the length direction of the second plate 41 is achieved by adjusting the second mounting plate assembly 45. Then, insert the first screw 3 into the inside of the first connecting sleeve 23 and fix the first nut 7, insert the second screw 5 into the second connecting sleeve 43 and fix the second nut 8 to complete the adjustment and assembly of the tooling. This allows it to be used for gearbox secondary sun shaft baffles with size changes without having to replace all parts of the tooling, thus reducing the manufacturing and use costs of the tooling.
