Description

Technical Field

[0001] This utility model belongs to the field of gearbox processing technology, and in particular relates to a fixture for processing reducer gearboxes. Background Technology

[0002] A speed reducer is an independent component consisting of gear transmission, worm transmission, or gear and worm transmission enclosed in a rigid housing. It is used as a speed reduction transmission device between the prime mover and the working machine. Its main function is to convert high-speed, low-torque power into low-speed, high-torque power, achieving a match between speed and torque. This makes speed reducers widely used in industries such as metallurgy, mining, hoisting, construction, food, and light industry, and they can adapt to the low-speed, high-torque requirements of different equipment.

[0003] During the machining of gearboxes, some gearboxes have irregular outer surfaces, resulting in a small contact area between the gearbox and the traditional clamping fixture. This makes it difficult to clamp and fix the gearbox housing, which can affect subsequent machining. To solve this problem, there is an urgent need for a new type of clamping fixture for machining gearboxes. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the contact area between the traditional clamp and the gearbox is small due to the irregular shape of the outer wall of some gearboxes, which makes it inconvenient to fix them. Therefore, a clamp for processing reducer gearboxes is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fixture for processing a reducer gearbox, comprising a base, wherein a rack is fixedly installed on the inner wall of a groove opened on the top surface of the base, and a bidirectional threaded rod is provided on the top surface of the base; a clamping assembly, wherein two clamping assemblies are provided and are respectively located on both sides of the base; and a support assembly, wherein the support assembly is disposed on the top surface of the base and is located between the clamping assemblies.

[0006] The clamping assembly includes a fixing plate with a spring pin in a groove on one side. Multiple spring pins are provided. A mounting sleeve is fixedly installed on one side of the fixing plate. A support rod is slidably mounted on the mounting sleeve through a groove. A threaded rod is threadedly connected to the support rod through a threaded hole. A gear is fixedly mounted at the bottom end of the threaded rod. A support is fixedly installed on one side of the fixing plate. An mounting rod is slidably mounted on the outer wall of the support rod. A fixing rod is fixedly mounted on one side of the mounting rod. A sliding rod is slidably mounted on the fixing rod through a through hole. A pressure plate is fixedly mounted at the bottom end of the sliding rod. A spring is provided on the outer wall of the sliding rod. A fixing buckle is provided on the mounting rod through a groove on one side. The mounting rod can contact the outer wall of the gearbox through the spring pins, ensuring sufficient contact area with the gearbox. Simultaneously, the pressure plate applies pressure to the top surface of the gearbox, further ensuring its fixation.

[0007] As a further description of the above technical solution:

[0008] The fixing buckle engages with the support rod through a groove on one side, and the support rod has multiple grooves on one side.

[0009] As a further description of the above technical solution:

[0010] The threaded rod is rotatably connected to the support through a through hole, and the fixed plate is slidably connected to the base through a groove on the top surface of the base.

[0011] As a further description of the above technical solution:

[0012] The bidirectional threaded rod is threadedly connected to the fixed plate through a threaded hole, and one side of the gear is meshed with the rack.

[0013] As a further description of the above technical solution:

[0014] The support assembly includes a support base, a limit block is fixedly installed on the top surface of the support base, a movable frame is slidably installed on the support base through a groove opened on its top surface, and a rotating shaft is rotatably installed on the movable frame through a through hole opened inside it.

[0015] As a further description of the above technical solution:

[0016] An electric push rod is fixedly installed on the outer wall of the rotating shaft. A hinge joint is fixedly installed on the telescopic end of the electric push rod. A connecting column is rotatably installed on the movable frame through a through hole. The electric push rod drives the support plate to rotate and make the support plate contact the inclined surface at one end of the gearbox, thereby providing auxiliary support for the gearbox and preventing it from tilting.

[0017] As a further description of the above technical solution:

[0018] A support plate is fixedly installed on one side of the connecting column, and a hinge seat is fixedly installed on the bottom surface of the support plate. The hinge seat is hinged to the hinge joint, and the bottom surface of the support seat is fixedly connected to the base.

[0019] As a further description of the above technical solution:

[0020] The bidirectional threaded rod is rotatably connected to the support base through a through hole. The support base is slidably mounted with a fixing pin through a through hole. The fixing pin is slidably connected to the movable frame through through holes on both sides.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] In this invention, a clamping assembly is provided inside. This design enables the gearbox to be clamped and fixed by a spring pin on one side of the fixing plate, ensuring that the clamp can fully contact both sides of the gearbox and thus guaranteeing the fixing effect. Furthermore, during the movement of the fixing plate, the rack drives the gear to rotate, which in turn drives the threaded rod to rotate and causes the pressure plate to move with the downward movement of the support rod. This pressure plate presses down on the top surface of the gearbox, further fixing the gearbox and ensuring the stability of the gearbox fixation.

[0023] In this invention, a support assembly is provided inside. This design allows the support plate to rotate via an electric push rod during gearbox processing, causing the support plate to contact the inclined surface at one end of the gearbox. The electric push rod and the support plate then support one end of the gearbox, preventing the gearbox from tilting due to a shift in its center of gravity and ensuring the top of the gearbox is level. This facilitates the worker's processing of the gearbox's interior. Before support is applied, the moving frame can be moved to a suitable position and secured with a fixing pin, thus ensuring the support effect of the support plate and the electric push rod.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] In its specific implementation, such as Figures 1-5 This utility model provides a technical solution: a fixture for processing a reducer gearbox, including a base 1, a rack 2 fixedly installed on the inner wall of a groove opened on the top surface of the base 1, and a bidirectional threaded rod 5 provided on the top surface of the base 1; a clamping assembly 4, two clamping assemblies 4 are provided and are respectively located on both sides of the base 1; and a support assembly 3, the support assembly 3 is disposed on the top surface of the base 1 and is located between the clamping assemblies 4.

[0033] The clamping assembly 4 includes a fixing plate 42. A spring pin 41 is provided in a groove on one side of the fixing plate 42, and multiple spring pins 41 are provided. An mounting sleeve 413 is fixedly installed on one side of the fixing plate 42. A support rod 44 is slidably mounted on the mounting sleeve 413 through a groove therein. A threaded rod 49 is threadedly connected to the support rod 44 through a threaded hole therein. A gear 410 is fixedly installed at the bottom end of the threaded rod 49. A support 412 is fixedly installed on one side of the fixing plate 42. An mounting rod 43 is slidably mounted on the outer wall of the support rod 44. A fixing rod 45 is fixedly installed on one side of the mounting rod 43. The fixing rod 45 is connected via… A sliding rod 46 is slidably installed in the through hole. A pressure plate 48 is fixedly installed at the bottom end of the sliding rod 46. A spring 47 is provided on the outer wall of the sliding rod 46. A fixing buckle 411 is provided through a groove on one side of the mounting rod 43. The fixing buckle 411 is engaged with the support rod 44 through a groove on one side. The support rod 44 has multiple grooves on one side. The threaded rod 49 is rotatably connected to the support 412 through a through hole. The fixing plate 42 is slidably connected to the base 1 through a groove on the top surface. The bidirectional threaded rod 5 is threadedly connected to the fixing plate 42 through a threaded hole. One side of the gear 410 is meshed with the rack 2.

[0034] During the processing of the gearbox, it is placed on the surface of the support assembly 3. Then, by rotating the double-threaded rod 5, the fixing plate 42 is moved, causing the fixing plates 42 on both sides of the base 1 to move towards the center. When the fixing plate 42 approaches the gearbox, the gearbox will compress the spring pin 41, causing part of the spring pin 41 on one side of the fixing plate 42 to gradually retract into the fixing plate 42 after being compressed by the gearbox. During the movement of the fixing plate 42, it can drive the gear 410 to move, thereby driving the gear 410 through the rack 2 during the movement. The rotating gear 410 drives the threaded rod 49 to rotate, which in turn drives the support rod 44 and the mounting rod 43 to move downwards, thereby driving the fixing rod 45 and the pressure plate 48 to move downwards. At the same time, after the pressure plate 48 is released from the gearbox, if the fixing plate 42 continues to move, the spring 47 can be gradually compressed, thereby further fixing the gearbox. Before clamping, the fixing buckle 411 can be pulled out and the mounting rod 43 can be slid to move it to a suitable height and then the fixing buckle 411 can be reconnected to the support rod 44, thereby ensuring that the pressure plate 48 is at a suitable height.

[0035] like Figure 3As shown, the support assembly 3 includes a support base 32. A limit block 31 is fixedly installed on the top surface of the support base 32. A movable frame 310 is slidably installed on the support base 32 through a groove on its top surface. A rotating shaft 37 is rotatably installed on the movable frame 310 through a through hole. An electric push rod 38 is fixedly installed on the outer wall of the rotating shaft 37. A hinge joint 39 is fixedly installed at the telescopic end of the electric push rod 38. A connecting column 33 is rotatably installed on the movable frame 310 through a through hole. A support plate 35 is fixedly installed on one side of the connecting column 33. A hinge seat 36 is fixedly installed on the bottom surface of the support plate 35. The hinge seat 36 is hinged to the hinge joint 39. The bottom surface of the support base 32 is fixedly connected to the base 1. A bidirectional threaded rod 5 is rotatably connected to the support base 32 through a through hole. A fixing pin 34 is slidably installed on the support base 32 through a through hole. The fixing pin 34 is slidably connected to the movable frame 310 through through holes on both sides.

[0036] When machining the gearbox, the fixing pin 34 is pulled out and the moving frame 310 is slid to move it to the appropriate position. Then, the fixing pin 34 is reinserted into the moving frame 310 and the support base 32 to fix the moving frame 310. The gearbox is then placed on the surface of the support base 32 and one side of it contacts the limiting block 31. The electric push rod 38 is then activated to extend its telescopic end. This causes the support plate 35 to rotate around the connecting column 33 through the hinge joint 39 and the hinge base 36, and the rotating shaft 37 to rotate. This causes the support plate 35 to contact the inclined surface at one end of the gearbox and to be supported by the electric push rod 38 and the support plate 35, thus ensuring that the top surface of the gearbox remains horizontal, which facilitates machining by the worker.

[0037] Working principle: When machining the gearbox, the fixing pin 34 is pulled out and the sliding frame 310 is moved to a suitable position. The fixing pin 34 is then reinserted into the moving frame 310 and support base 32 to fix the moving frame 310. The gearbox is then placed on the surface of the support base 32 with one side in contact with the limiting block 31. The electric push rod 38 is activated to extend its telescopic end, causing the support plate 35 to rotate around the connecting column 33 via the hinge joint 39 and hinge base 36. This rotation of the rotating shaft 37 brings the support plate 35 into contact with the inclined surface at one end of the gearbox, where it is supported by the electric push rod 38 and the support plate 35, ensuring the top surface of the gearbox remains level for easy machining. The bidirectional threaded rod 5 is then rotated to move the fixing plate 42, causing the fixing plates 42 on both sides of the base 1 to move towards the center. When plate 42 approaches the gearbox, the gearbox will compress the spring pin 41, causing part of the spring pin 41 on one side of the fixed plate 42 to gradually retract into the fixed plate 42 after being compressed by the gearbox. During the movement of the fixed plate 42, it can drive the gear 410 to move, thereby driving the gear 410 to rotate through the rack 2, which in turn drives the threaded rod 49 to rotate, and drives the support rod 44 and the mounting rod 43 to move downward, thereby driving the fixed rod 45 and the pressure plate 48 to move downward. At the same time, when the pressure plate 48 is released from the gearbox, if the fixed plate 42 continues to move, the spring 47 can be gradually compressed, thereby further fixing the gearbox. Before clamping, the fixing buckle 411 can be pulled out and the mounting rod 43 can be slid to move it to a suitable height and then the fixing buckle 411 can be reconnected to the support rod 44 to ensure that the pressure plate 48 is at a suitable height.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
