Description

Technical Field

[0001] The utility model relates to the technical field of gearbox tooling, and particularly relates to a gearbox processing tooling with a positioning mechanism. Background Art

[0002] In the mechanical processing industry, tooling refers to devices used for positioning, clamping, supporting, and detecting workpieces, and these tooling devices are crucial for the mechanical processing process. A gearbox is an important mechanical transmission device, and its main function is to convert the rotational speed and torque of the input shaft into different rotational speeds and torques of the output shaft. The gearbox tooling adapted to the gearbox refers to an auxiliary device used to ensure the stability and accuracy of the workpiece during grinding, processing, or assembly in the gearbox processing process.

[0003] The utility model patent with the publication number of CN207138920U discloses a gearbox drilling tooling. At least two gearboxes can be placed on the support of this utility model at the same time, and the lower part presses and fixes the gearboxes through a pressing mechanism, achieving the purpose of machining two gearboxes simultaneously in one clamping, reducing the auxiliary processing time and the labor intensity of workers, and improving the processing efficiency.

[0004] The above tooling fixes the gearbox by clamping. Since the size of its clamping plate is large, it will cause a large area of covering on the surface of the gearbox, and it is impossible to machine four surfaces at the same time. There is also a possibility of interfering with the movement of the processing equipment. Moreover, after the gearbox is clamped in it, it cannot be rotated to adjust the processing angle. When multiple surfaces or multiple angles need to be machined during use, the gearbox needs to be frequently disassembled and assembled, which is rather inconvenient. Therefore, in view of the above problems, a gearbox processing tooling with a positioning mechanism is proposed now. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a gearbox processing tooling with a positioning mechanism. This gearbox tooling can install the gearbox housing on the positioning mounting frame through bolts, playing a role of positioning and mounting. Since the positioning mounting frame is only connected to both ends of the gearbox, it will not cover a large area of the gearbox, facilitating the machining of multiple surfaces of the gearbox. In addition, the driving mechanism can drive the positioning mounting frame to rotate, thereby driving the gearbox mounted on it to rotate, facilitating the rapid replacement of the machining surface during processing and fixing the gearbox at a specified angle, meeting different processing requirements, and eliminating the need for frequent disassembly and assembly of the gearbox. It solves the technical problems that the clamping mechanism in the prior art will cause a large area of covering on the surface of the gearbox and cannot rotate to adjust the processing angle. When multiple surfaces or multiple angles need to be machined during use, the gearbox needs to be frequently disassembled and assembled, thus affecting the processing efficiency.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problems is:

[0007] A gearbox processing tooling with a positioning mechanism includes a base plate provided with a guide rail thereon, a fixed support plate fixedly arranged at one end of the base plate, and a movable support plate slidably arranged in the guide rail. Among them, rotating shaft seats are provided at the tops of both the fixed support plate and the movable support plate, and a positioning mounting frame is connected to the rotating shaft seats. A driving mechanism is provided on the base plate for driving the rotating shaft seat on the fixed support plate to rotate.

[0008] With the above structural form, the gearbox housing can be installed on the positioning mounting frame with bolts, which has the function of positioning and installation. Since the positioning mounting frame is only connected to both ends of the gearbox, it will not cover a large area of the gearbox, facilitating the machining of multiple surfaces of the gearbox. In addition, the driving mechanism can drive the positioning mounting frame to rotate, thereby driving the gearbox mounted thereon to rotate, facilitating the rapid replacement of the machining surface during machining and fixing the gearbox at a specified angle to meet different machining requirements without frequent disassembly and assembly of the gearbox.

[0009] In a possible implementation manner, the positioning mounting frame includes an L-shaped support plate, and a positioning plate is detachably installed on the L-shaped support plate. Threaded holes are provided on the positioning plate that fit the gearbox housing to be fixed.

[0010] With the above structural form, the L-shaped support plate can play a role in fixedly supporting both ends of the gearbox, while the detachable positioning plate serves as a connection medium, enabling the replacement of the positioning plate with corresponding dimensions according to the gearbox with different hole-opening conditions to ensure a reliable connection between the L-shaped support plate and different gearboxes.

[0011] In a possible implementation manner, a plug shaft is fixedly arranged on the lower end surface of the positioning plate, a through hole matching the plug shaft is provided on the L-shaped support plate, and a fastening nut is threadedly connected to the bottom end of the plug shaft.

[0012] With the above structural form, the detachable connection between the positioning plate and the L-shaped support plate can be realized by inserting the plug shaft into the through hole of the positioning plate, facilitating the replacement of the corresponding positioning plate according to the specific situation of the gearbox.

[0013] In a possible implementation manner, the movable support plate includes a sliding table slidably arranged between the guide rails, a support plate body is fixedly connected to the sliding table, locking shafts are provided on both sides of the sliding table in the guide rail grooves, and locking wheels are threadedly connected to the locking shafts.

[0014] With the above structural form, the sliding connection between the movable support plate and the bottom plate can be realized in the way that the sliding table slides along the guide rail, which is convenient for changing the distance between the fixed support plate and the movable support plate, so as to meet the installation requirements of gearboxes of different sizes. And when it is necessary to fix the position of the sliding table, tighten the locking wheel, and the position of the sliding table can be fixed by relying on the friction between the locking wheel and the guide rail.

[0015] In a possible implementation manner, a guide groove is formed on the bottom plate, a guide bar is fixedly arranged on the lower end surface of the sliding table, and the cross-sectional shape of the guide bar fits the cross-sectional shape of the guide groove.

[0016] With the above structural form, the sliding of the sliding table is restricted and guided in the way that the guide bar slides in the guide groove, avoiding the deviation of the sliding table during the sliding process.

[0017] In a possible implementation manner, the rotating shaft seat includes a connecting outer cylinder and a transmission shaft. Two mounting bearings are fixedly arranged in the connecting outer cylinder, and the transmission shaft is fixedly connected to the inner ring of the mounting bearing.

[0018] With the above structural form, since the transmission shaft can rotate freely, the positioning mounting frame connected thereto can also rotate freely, providing a necessary structural basis for adjusting the machining angle of the gearbox.

[0019] In a possible implementation manner, the driving mechanism includes a mounting vertical plate, and a driving motor and a speed reducer are sequentially mounted on the mounting vertical plate from top to bottom.

[0020] With the above structural form, the mounting vertical plate can provide a necessary structural basis for the installation, fixation and operation of the driving motor and the speed reducer.

[0021] In a possible implementation manner, the output shaft of the speed reducer is fixedly connected to the transmission shaft, and the input shaft of the speed reducer is fixedly connected to the output shaft of the driving motor.

[0022] With the above structural form, the torque output by the driving motor can be transmitted to the transmission shaft through the speed reducer, and the self-locking function of the speed reducer can also ensure that when the driving motor does not work, the transmission shaft cannot drive the speed reducer to rotate, realizing the fixation of the rotation angle of the gearbox mounted on the positioning mounting frame.

[0023] In summary, the present utility model includes the following beneficial technical effects:

[0024] The gearbox housing can be installed on the positioning mounting frame with bolts, which has the function of positioning and mounting. Since the positioning mounting frame is only connected to both ends of the gearbox, it will not cover a large area of the gearbox, facilitating the machining of multiple surfaces of the gearbox. In addition, the driving mechanism can drive the positioning mounting frame to rotate, thereby driving the gearbox mounted on it to rotate, facilitating the rapid replacement of the machining surface during machining and fixing the gearbox at a specified angle to meet different machining requirements without frequent disassembly and assembly of the gearbox.

Detailed Description of the Embodiment

[0031] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0032] As Figure 1 - Figure 2As shown in the figure, a gearbox processing tooling with a positioning mechanism provided in this embodiment includes a bottom plate 1, on which a guide rail 11 is provided, a fixed support plate 2 fixedly arranged at one end of the bottom plate 1, and a movable support plate 3 slidably arranged in the guide rail 11. Among them, rotating shaft seats 4 are provided at the tops of both the fixed support plate 2 and the movable support plate 3, and a positioning mounting frame 5 is connected to the rotating shaft seats 4. A driving mechanism 6 is provided on the bottom plate 1, which is used to drive the rotating shaft seat 4 on the fixed support plate 2 to rotate. Through the above structural form, the gearbox housing can be installed on the positioning mounting frame 5 with bolts, which has the function of positioning and installation. Since the positioning mounting frame 5 is only connected to both ends of the gearbox, it will not cover a large area of the gearbox, and it is convenient to machine multiple surfaces of the gearbox. In addition, the driving mechanism 6 can drive the positioning mounting frame 5 to rotate, thereby driving the gearbox installed on it to rotate, which is convenient to quickly change the machining surface during machining and fix the gearbox at a specified angle, meeting different machining requirements without frequent disassembly and assembly of the gearbox.

[0033] As Figure 3 shown, the positioning mounting frame 5 includes an L-shaped support plate 51, and a positioning plate 52 is detachably installed on the L-shaped support plate 51. Thread holes are provided on the positioning plate 52 to fit the gearbox housing to be fixed. Through the above structural form, the L-shaped support plate 51 can play a role in fixedly supporting both ends of the gearbox, and the detachable positioning plate 52 plays the role of a connection medium, and the positioning plate 52 with corresponding dimensions can be replaced according to the gearbox with different hole-opening situations to ensure that a reliable connection can be generated between the L-shaped support plate 51 and different gearboxes.

[0034] Among them, a plug-in shaft 53 is fixedly arranged on the lower end surface of the positioning plate 52, a through hole matching the plug-in shaft 53 is provided on the L-shaped support plate 51, and a fastening nut 54 is threadedly connected to the bottom end of the plug-in shaft 53. The detachable connection between the positioning plate 52 and the L-shaped support plate 51 can be realized by inserting the plug-in shaft 53 into the through hole of the positioning plate 52, which is convenient to replace the corresponding positioning plate 52 according to the specific situation of the gearbox.

[0035] As Figure 2 shown, the movable support plate 3 includes a sliding table 31 slidably arranged between the guide rails 11, a support plate body 32 is fixedly connected to the sliding table 31, locking shafts 33 are provided on both sides of the sliding table 31 in the grooves of the guide rail 11, and locking wheels 34 are threadedly connected to the locking shafts 33. Through the above structural form, the sliding connection between the movable support plate 3 and the bottom plate 1 can be realized by sliding the sliding table 31 along the guide rail 11, which is convenient to change the distance between the fixed support plate 2 and the movable support plate 3, and thus meet the installation requirements of gearboxes with different sizes. And when it is necessary to fix the position of the sliding table 31, by tightening the locking wheel 34, the position of the sliding table 31 can be fixed by relying on the friction between the locking wheel 34 and the guide rail 11.

[0036] Among them, a guide groove 12 is formed on the bottom plate 1. A guide bar 35 is fixedly arranged on the lower end surface of the sliding table 31, and the cross-sectional shape of the guide bar 35 fits the cross-sectional shape of the guide groove 12. Through the above structural form, in the way that the guide bar 35 slides in the guide groove 12, it plays a role in restricting and guiding the sliding of the sliding table 31, avoiding the deviation of the sliding table 31 during the sliding process.

[0037] As Figure 4 shown, the rotating shaft seat 4 includes a connecting outer cylinder 41 and a transmission shaft 43. Two mounting bearings 42 are fixedly arranged inside the connecting outer cylinder 41, and the transmission shaft 43 is fixedly connected to the inner ring of the mounting bearing 42. Through the above structural form, since the transmission shaft 43 can rotate freely, the positioning mounting frame 5 connected thereto can also rotate freely, providing a necessary structural basis for adjusting the processing angle of the gearbox.

[0038] As Figure 3 shown, the driving mechanism 6 includes a mounting vertical plate 61. A driving motor 62 and a speed reducer 63 are successively mounted on the mounting vertical plate 61 from top to bottom. Through the above structural form, it can provide a necessary structural basis for the mounting and fixing and operation of the driving motor 62 and the speed reducer 63 with the mounting vertical plate 61.

[0039] Among them, the output shaft of the speed reducer 63 is fixedly connected to the transmission shaft 43, and the input shaft of the speed reducer 63 is fixedly connected to the output shaft of the driving motor 62. Through the above structural form, the torque output by the driving motor 62 can be transmitted to the transmission shaft 43 through the speed reducer 63, and the self-locking function of the speed reducer 63 can also ensure that when the driving motor 62 does not work, the transmission shaft 43 cannot drive the speed reducer 63 to rotate, realizing the fixation of the rotation angle of the gearbox mounted on the positioning mounting frame 5.

[0040] The working principle and process of the present utility model:

[0041] The gearbox housing can be installed on the positioning mounting frame 5 with bolts, which has the function of positioning and installation. Since the positioning mounting frame 5 is only connected to both ends of the gearbox, it will not cover a large area of the gearbox, facilitating the processing of multiple surfaces of the gearbox. In addition, the driving mechanism 6 can drive the positioning mounting frame 5 to rotate, thereby driving the gearbox mounted thereon to rotate, facilitating the rapid replacement of the processing surface during processing and fixing the gearbox at a specified angle, meeting different processing requirements without frequent disassembly and assembly of the gearbox.

[0042] In the above structure, the positioning mounting frame 5 plays a role in fixedly supporting both ends of the gearbox with the L-shaped support plate 51, while the detachable positioning plate 52 plays the role of a connection medium, and can replace the positioning plate 52 with corresponding dimensions according to the gearboxes with different opening conditions, ensuring a reliable connection between the L-shaped support plate 51 and different gearboxes.

[0043] In addition, the sliding connection between the movable support plate 3 and the bottom plate 1 can be realized in such a way that the sliding table 31 slides along the guide rail 11, which is convenient for changing the distance between the fixed support plate 2 and the movable support plate 3, so as to meet the installation requirements of gearboxes of different sizes. And when the position of the sliding table 31 needs to be fixed, by tightening the locking wheel 34, the position of the sliding table 31 can be fixed by relying on the friction between the locking wheel 34 and the guide rail 11.

[0044] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
