[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1

[0028] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a machining fixture for a gearbox housing. The machining fixture for a gearbox housing includes a main body component 100 and a clamping component 200. The two components work together to adaptively clamp gearbox housings of different shapes.

[0029] The main component 100 includes a processing table 101, a tapping machine 102, and a support frame 103. The support frame 103 is fixed to the top of the processing table 101, and the tapping machine 102 is located on one side of the support frame 103.

[0030] The machining table 101 provides a stable placement and support platform for the gearbox housing, ensuring that the housing remains in a fixed position during machining without shaking or shifting, thus guaranteeing machining accuracy. The tapping machine 102 is used to machine internal threads on the gearbox housing. It drills threaded holes in the housing using a rotating tap, facilitating the subsequent installation of bolts and other fasteners to connect and secure the components. The support frame 103 supports the tapping machine 102, preventing it from shifting. The tapping machine 102 is existing technology and will not be described in detail.

[0031] The clamping assembly 200 is disposed on the processing table 101 and includes a clamping member 201, a driving member 202 and a limiting member 203. The clamping member 201 is disposed on the top of the processing table 101, the driving member 202 is disposed on the clamping member 201, and the limiting member 203 is located on the driving member 202.

[0032] There are two sets of clamping members 201, both located on the top of the processing table 101. The clamping members 201 can adaptively clamp the gearbox housing according to its shape, facilitating subsequent processing of the gearbox housing. There are also two sets of driving members 202, both located on the clamping members 201. The movement of the driving members 202 can drive the clamping members 201 to move, allowing the clamping members 201 to clamp the gearbox housing. After clamping the gearbox housing, in order to prevent the driving members 202 from being accidentally moved, the limiting member 203 can limit the driving members 202, thereby preventing them from being accidentally moved.

[0033] Example 2

[0034] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, the clamping component 201 includes a clamping plate 201a and a roller 201b. The clamping plate 201a is disposed on the top of the processing table 101, and the roller 201b is movably connected to one side of the clamping plate 201a.

[0036] When the gearbox housing needs to be processed, the gearbox housing is first placed on the processing table 101, and then the two clamping plates 201a are moved towards each other. The movement of the clamping plates 201a causes the rollers 201b to move to contact one side of the gearbox housing, thereby fixing the gearbox housing.

[0037] Specifically, the clamping member 201 also includes a movable plate 201c and a movable rod 201d. The movable plate 201c is hinged to one side of the clamping plate 201a, and the movable rod 201d is fixed to one side of the movable plate 201c.

[0038] The movement of the movable plate 201c will drive the clamping plate 201a to move. When it is necessary to clamp an irregularly shaped gearbox housing, the clamping plate 201a can rotate according to the shape of the gearbox housing when the roller 201b contacts one side of the gearbox housing. This allows the rollers 201b on both sides of the clamping plate 201a to contact one side of the gearbox housing, thereby completing the clamping of the gearbox housing. The movement of the movable rod 201d can drive the movable plate 201c to move.

[0039] Specifically, the clamping member 201 also includes a rotating shaft 201e and a first torsion spring 201f. The rotating shaft 201e is inserted into the top of the moving plate 201c, and one end of the first torsion spring 201f is fixed to the top of the moving plate 201c, and the other end is fixed to the bottom of the clamping plate 201a.

[0040] The clamping plate 201a is sleeved on the outside of the rotating shaft 201e. The clamping plate 201a is movably connected to the rotating shaft 201e. The rotating shaft 201e is used to support the clamping plate 201a and prevent the clamping plate 201a from shifting when rotating. When the clamping plate 201a rotates, it can apply a torsional force to the first torsion spring 201f. When the clamping plate 201a is moved to the side of the gearbox housing, the force of the first torsion spring 201f can drive the clamping plate 201a back to its original position for the next use.

[0041] Specifically, the clamping component 201 also includes a support sleeve 201g and a base 201h. The support sleeve 201g is sleeved on the outside of the moving rod 201d and is movably connected to the moving rod 201d. The base 201h is fixed to the bottom of the support sleeve 201g.

[0042] The support sleeve 201g is used to support the moving rod 201d to prevent the moving rod 201d from shifting during movement. The base 201h is fixed to the top of the processing table 101. The base 201h can support the support sleeve 201g to prevent the support sleeve 201g from shifting.

[0043] Specifically, the driving component 202 includes a driving rod 202a, a positioning shaft 202b, and a second torsion spring 202c. The driving rod 202a is hinged to one end of the moving rod 201d. The positioning shaft 202b is fixed to the bottom of the driving rod 202a. One end of the second torsion spring 202c is fixed to the bottom of the driving rod 202a, and the other end is fixed to the top of the processing table 101.

[0044] When it is necessary to move the moving rod 201d, the driving rod 202a is moved so that one end of the driving rod 202a can press against the moving rod 201d, thereby moving the moving rod 201d. The positioning shaft 202b is movably connected to the top of the processing table 101. When the driving rod 202a moves, it can drive the positioning shaft 202b to rotate. The rotation of the positioning shaft 202b can apply a torsional force to the second torsion spring 202c. When it is necessary to release the pressure of the driving rod 202a on the moving rod 201d, the force of the rotation of the second torsion spring 202c can drive the driving rod 202a back to its original position, thereby releasing the pressure on the moving rod 201d.

[0045] Specifically, the drive component 202 also includes a movable rod 202d and a rack 202e. The movable rod 202d is fixed to one end of the drive rod 202a, and the rack 202e is fixed to the bottom of the movable rod 202d.

[0046] The movement of rack 202e can drive the movable rod 202d to move, and the movement of movable rod 202d can drive the drive rod 202a to move, so that one end of drive rod 202a can squeeze the movable rod 201d.

[0047] Example 3

[0048] Reference Figures 2-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0049] Specifically, the drive unit 202 also includes a gear 202f, a protective cover 202g, and a handle 203h. The gear 202f is located at the bottom of the rack 202e and meshes with the rack 202e. The protective cover 202g is fixed to one side of the processing table 101, and the handle 203h is fixed to one side of the gear 202f.

[0050] Gear 202f is located between two racks 202e and meshes with them. When gear 202f rotates, it can simultaneously drive the two racks 202e to move in opposite directions. The movement of the racks 202e can drive the movable rod 202d to move. A sliding groove is provided on the protective cover 202g, and the movable rod 202d slides in the groove. The protective cover 202g is used to protect gear 202f from being hit by external debris and damaged. Handle 203h is inserted into one side of the protective cover 202g and is movably connected to the protective cover 202g. The handle 203h facilitates the user to rotate gear 202f.

[0051] Specifically, the limiting component 203 includes a limiting sleeve 203a and a limiting block 203b. The limiting sleeve 203a is sleeved on the outside of the handle 203h, and the limiting block 203b is located on top of the limiting sleeve 203a.

[0052] A limiting groove corresponding to the limiting block 203b is provided on the limiting sleeve 203a. The bottom of the limiting block 203b is set as an inclined surface. When the handle 203h is rotated, it will drive the limiting sleeve 203a to rotate. When the handle 203h rotates to clamp the gearbox housing, the limiting block 203b will not limit the limiting sleeve 203a. After clamping the gearbox housing, the limiting sleeve 203a can be limited by the engagement of the limiting block 203b and the limiting groove, thus preventing the handle 203h from reversing.

[0053] Specifically, the limiting component 203 also includes a connecting shaft 203c and a third torsion spring 203d. The connecting shaft 203c is fixed to one side of the limiting block 203b, and one end of the third torsion spring 203d is fixed to one side of the limiting block 203b, while the other end is fixed to one side of the processing table 101.

[0054] The connecting shaft 203c is movably connected to one side of the processing table 101. When it is necessary to reverse the handle 203h to release it from the clamping of the gearbox housing, the limiting block 203b is moved. When the limiting block 203b moves, it can drive the connecting shaft 203c to rotate. When the connecting shaft 203c rotates, it can apply a torsional force to the third torsion spring 203d. The limiting block 203b moves and separates from the limiting sleeve 203a, thereby releasing the limiting of the handle 203h. This allows the handle 203h to reverse and release the clamping of the gearbox housing. Then the limiting block 203b is released. At this time, the force of the rotation of the third torsion spring 203d can drive the limiting block 203b to engage with the limiting sleeve 203a, and limit the handle 203h in one direction again for the next use.

[0055] In use, when machining the gearbox housing, the gearbox housing is first placed on the machining table 101. The gearbox housing needs to be clamped. Rotating the handle 203h drives the gear 202f to rotate. When the gear 202f rotates, it simultaneously drives the two racks 202e to move towards each other. The movement of the racks 202e drives the movable rod 202d to move, which in turn drives the drive rod 202a to move. This allows one end of the drive rod 202a to press against the movable rod 201d, causing it to move. The movement of the drive rod 202a drives the positioning shaft 202b to rotate. The rotation of the positioning shaft 202b applies a torsional force to the second torsion spring 202c. The movable rod 201d... The movement of plate 1d can move the moving plate 201c, which in turn moves the clamping plate 201a. The two clamping plates 201a move towards each other, causing the rollers 201b to move to contact one side of the gearbox housing, thus fixing the gearbox housing. When dealing with irregularly shaped gearbox housings, the contact between the rollers 201b and one side of the gearbox housing allows the clamping plate 201a to rotate according to the shape of the gearbox housing, so that both rollers 201b on both sides of the clamping plate 201a are in contact with one side of the gearbox housing. When the clamping plate 201a rotates, it can apply a torsional force to the first torsion spring 201f, thereby clamping the gearbox housing. Then, the gearbox housing can be processed by the tapping machine 102.

[0056] After the gearbox housing is machined, it needs to be removed. First, the limiting position on the handle 203h needs to be released. This is done by moving the limiting block 203b. When the limiting block 203b moves, it drives the connecting shaft 203c to rotate. The rotation of the connecting shaft 203c applies a torsional force to the third torsion spring 203d. The movement of the limiting block 203b separates it from the limiting sleeve 203a, thus releasing the limiting position on the handle 203h. This allows the handle 203h to reverse and release its grip on the gearbox housing. The reverse rotation of the handle 203h also causes the drive rod 202a to release its pressure on the moving rod 201d. The pressure, through the force of the second torsion spring 202c rotating, can drive the drive rod 202a back to its original position, thereby relieving the pressure on the moving rod 201d. The return of the drive rod 202a to its original position allows the clamping plate 201a to move to the side of the gearbox housing and separate. The force of the first torsion spring 201f rotating can drive the clamping plate 201a back to its original position, thereby allowing the gearbox housing to be removed. Then, the limiting block 203b is released. At this time, the force of the third torsion spring 203d rotating can drive the limiting block 203b to engage with the limiting sleeve 203a, and limit the handle 203h in one direction again for the next use.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
