Description

Technical Field

[0001] This utility model relates to the field of installation fixture technology, specifically a variable speed gearbox installation fixture. Background Technology

[0002] Currently, in the automotive manufacturing industry, the transmission gearbox is one of the core transmission components. The transmission gearbox achieves changes in torque and speed through the meshing of gears with different numbers of teeth. When the ratio of the number of teeth between the gears changes, the speed and torque will also change accordingly, thereby achieving a balance between the speed and torque of the motor. When installing the transmission gearbox, it needs to be transported to the required location. During the processing and installation of the transmission gearbox, clamps are required for fixation before installation.

[0003] For example, Chinese patent CN220637678U discloses a gearbox mounting fixture, including a base, a clamping body fitted on the top of the base, a clamping plate on the top of the clamping body, two adjusting rods fixedly inserted on the outer sides of the clamping plate, a central hole at the top center of the clamping plate, and several positioning holes evenly distributed around the central hole. A rotating rod is rotatably connected to one side of the outer surface of the clamping body via a rotating sleeve, and a rotating arm is fixedly connected to the end of the rotating rod. The rotating arm is located inside the clamping body, and one end of the rotating arm penetrates the clamping body and is fixedly clamped to the outer wall of the clamping body by a fixing bolt. A sleeve is provided at the bottom of the clamping plate. This utility model effectively improves the vibration damping performance of the gearbox during processing and installation, prevents vibration damage to the gearbox, improves the clamping stability of the gearbox, and greatly improves the installation efficiency of the gearbox.

[0004] While the aforementioned patent improves clamping stability and greatly enhances installation efficiency, the central hole of the patent is surrounded by several positioning holes arranged in a rectangular pattern, which makes it inconvenient to fix gearboxes of different sizes and reduces practicality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a gearbox mounting fixture that facilitates the fixing of gearboxes of different sizes. It solves the problem that the rectangular distribution of several positioning holes around the central hole makes it difficult to fix gearboxes of different sizes, thus reducing practicality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a variable speed gearbox mounting fixture, comprising a fixed frame and a fixed base, wherein mounting plates are provided on both the left and right sides of the fixed frame, and mounting holes are provided through the front and rear sides of the upper surface of the mounting plates, a fixing mechanism is provided on the upper surface of the fixed base, and an adjustment mechanism is provided inside the fixed frame;

[0007] The fixing mechanism includes a fixing groove, a first motor, a fixing plate, a rotating rod, a clamping plate, a connecting groove, and a connecting assembly. The fixing groove is formed on the upper surface of the fixing base. The first motor is disposed on the bottom wall of the inner cavity of the fixing groove. The fixing plate is disposed inside the fixing groove. The rotating rod is rotatably connected to the inside of the fixing plate through a bearing. The outer side of the output shaft of the first motor is fixedly connected to the bottom end of the rotating rod. The top end of the rotating rod is fixedly connected to the lower surface of the clamping plate. The connecting groove is formed on the upper surface of the clamping plate.

[0008] The connecting assembly includes four first positioning threaded holes, two second positioning threaded holes, three third positioning threaded holes, and four fourth positioning threaded holes. The four first positioning threaded holes are all formed on the upper surface of the clamping plate and are arranged in a rectangular pattern. The four second positioning threaded holes are all formed on the upper surface of the clamping plate and are arranged in a rectangular pattern. The four third positioning threaded holes are all formed on the upper surface of the clamping plate and are arranged in a rectangular pattern. The four fourth positioning threaded holes are all formed on the upper surface of the clamping plate and are arranged in a rectangular pattern.

[0009] This technical solution facilitates the fixing of gearboxes of different sizes.

[0010] Furthermore, ball bearings are rotatably connected to both sides of the lower surface of the clamping disc, and the lower surface of the ball bearings is in contact with the upper surface of the fixing base.

[0011] By adopting this technical solution, the stability of the clamping disc during left and right rotation can be improved through the left and right side ball bearings.

[0012] Furthermore, the adjustment mechanism includes a threaded rod, two limiting slide rods, a second motor, a moving block, and a connecting plate. The threaded rod is rotatably connected to the inside of the fixed frame via bearings. The two limiting slide rods are both located on the front and rear sides inside the fixed frame. The second motor is located on the left side of the fixed frame. The left side of the threaded rod rotatably passes through the fixed frame and is fixedly connected to the outside of the output shaft of the second motor.

[0013] By adopting this technical solution, the position of the left and right sides of the clamping disc can be adjusted through the adjustment mechanism.

[0014] Furthermore, the movable block is threaded to the outside of the threaded rod, the front and rear limiting slide rods are slidably connected to the inside of the movable block, the movable block is slidably connected to the inside of the fixed frame, the connecting plate is disposed on the upper surface of the movable block, and the fixed seat is fixed to the upper surface of the connecting plate by bolts.

[0015] By adopting this technical solution, the fixing seat can be removed from the upper surface of the connecting plate by twisting the bolts on the left and right sides of the lower surface of the connecting plate.

[0016] Furthermore, the movable block moves linearly left and right outside the front and rear limiting slide bars, and the gap between the limiting slide bars and the movable block is matched.

[0017] By adopting this technical solution, the moving block can be limited by the limiting slide bars on the front and rear sides to prevent rotation.

[0018] Furthermore, the mounting plates on the left and right sides are symmetrically distributed on the left and right sides of the longitudinal central axis of the fixed frame.

[0019] This technical solution improves the stability of the fixed frame during fixation.

[0020] Furthermore, the moving block moves linearly left and right inside the fixed frame.

[0021] By adopting this technical solution, the moving block can drive the clamping disk to move left and right when it moves left and right.

[0022] Furthermore, the gap between the movable block and the fixed frame is matched.

[0023] By adopting this technical solution, the stability of the moving block when moving left and right within the fixed frame is improved.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] 1. The gearbox mounting fixture can fix gearboxes of different sizes to be installed through four first positioning threaded holes, four second positioning threaded holes, four third positioning threaded holes and four fourth positioning threaded holes respectively.
