Description

Technical Field

[0001] This utility model relates to the field of assembly platform technology, specifically an adjustable speed reducer assembly platform. Background Technology

[0002] Currently, in the assembly process of speed reducers, the accuracy and efficiency of component positioning and adjustment directly affect assembly quality and production efficiency. Traditional assembly platforms mostly use fixed tooling or simple linear adjustment mechanisms, which have the problem of limited positioning methods: for speed reducer components of different specifications and shapes (such as housings, gear sets, etc.), special fixtures need to be changed frequently, resulting in high tooling costs and long changeover times, making it difficult to adapt to the flexible production needs of small batches and multiple varieties; at the same time, their adjustment mechanisms are mostly limited to linear reciprocating motion and lack full circumferential positioning capabilities. For components that need to be machined or assembled at multiple angles (such as multi-faceted mounting holes and annular welding positions), manual handling and adjustment of the workstations are required multiple times, which is not only inefficient but also makes it difficult to ensure positioning consistency, leading to accuracy deviations in key processes (such as hole machining and component docking), which seriously affects the assembly quality and production efficiency of speed reducers. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an adjustable speed reducer assembly platform, which has the advantage of adjusting the positioning mechanism to fix the position of components, and solves the problem that the adjusting mechanism is mostly limited to linear reciprocating motion and lacks full-circumferential positioning capability.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] An adjustable reducer assembly platform includes a workbench with a table surface. The workbench is equipped with a positioning mechanism for fixing components and an adjustment mechanism for adjusting the positioning position. The positioning mechanism includes brackets on both sides of the workbench, with a screw rotatably mounted on the brackets. A threaded sleeve is threaded onto the screw, and a frame that is slidably connected to the bottom end of the threaded sleeve is fixed to the frame. The frame is equipped with positioning claws and a transmission component for fixing components on the side.

[0006] Preferably, the transmission assembly includes a spring fixed to the inner side wall of the frame, a positioning claw slidably connected to the frame via a slide groove, the positioning claw being connected to the spring, a slide rod fixed to the positioning claw and slidably connected to the frame, a transmission plate rotatably mounted on the end of the slide rod, a slot being provided on the transmission plate, and a limiting strip corresponding to the slot being fixed to the frame.

[0007] Preferably, the adjustment mechanism includes gear rings fixedly connected to two supports respectively, two motors fixedly mounted on the worktable, and spur gears that mesh with the corresponding gear rings fixedly connected to the output ends of the motors. An annular groove is provided on the worktable, and the support is located in the annular groove and slidably connected to it.

[0008] Preferably, a handwheel is fixed to the top of the screw, and the screw is mounted on the frame via a nut seat.

[0009] Preferably, the inner surface of the positioning claw is provided with a removable wear-resistant pad, which is made of alloy steel.

[0010] Preferably, a control panel is installed on the workbench for controlling the operation of the drive motor.

[0011] By employing the above technical solution, this utility model provides an adjustable speed reducer assembly platform, which has at least the following beneficial effects:

[0012] 1. This adjustable reducer assembly platform can position components from above and below, or clamp components from both sides, adapting to components of different shapes. Combined with the transmission component, the positioning claws on both sides clamp towards the middle synchronously, forming a three-dimensional fixation, which can adapt to components of different shapes; the screw and sleeve transmission realizes high-precision stepless adjustment and self-locking.

[0013] 2. This adjustable reducer assembly platform allows the frame to move with the gear ring until it reaches the position of the corresponding component and stops. The positioning claw can then fix the component, and the position of the component can be adjusted. The motor drives the spur gear to rigidly mesh with the gear ring, causing the bracket to slide freely 360° along the annular groove. The rotation angle and position can be precisely controlled by the program, and it can quickly switch to any preset positioning point without manual intervention, significantly improving the positioning efficiency of multi-specification components or complex processes.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The adjustable speed reducer assembly platform provided by some embodiments of this utility model is described below with reference to the accompanying drawings.

[0025] Example 1:

[0026] Combination Figures 1-3 As shown, the adjustable reducer assembly platform provided by this utility model includes a worktable 100, a table surface 101 on the worktable 100, and a positioning mechanism 200 for fixing components on the worktable 100 to prevent components from shifting due to vibration or external force during processing and assembly, and to ensure the processing accuracy of key positions such as holes and edges. The worktable 100 is also provided with an adjustment mechanism 300 for adjusting the positioning position, which can adjust the positioning position to adapt to the positioning requirements under different working conditions and improve the processing quality of components.

[0027] The positioning mechanism 200 includes brackets 201 located on both sides of the worktable 100. A screw 202 is rotatably mounted on the brackets 201, and a threaded sleeve 203 is threadedly connected to the screw 202. A frame 205, which is slidably connected to the brackets 201, is fixed to the bottom end of the threaded sleeve 203. A positioning claw 206 is provided on the frame 205. When the screw 202 is rotated, the screw 202 rotates and drives the frame 205 on the threaded sleeve 203 to move downward. The positioning claw 206 moves with the frame 205, and then the positioning claw 206 fixes the component from top to bottom. The frame 205 is also provided with a transmission component for fixing the component from the side, so that the two positioning claws 206 can move from both sides to the middle to fix the component, which can adapt to components of different shapes. Combined with the transmission component, the positioning claws 206 on both sides clamp towards the middle at the same time to form a three-dimensional fixation, which can adapt to components of different shapes. The screw 202 and threaded sleeve 203 transmission realizes high-precision stepless adjustment and self-locking.

[0028] Specifically, the transmission assembly includes a spring 207 fixed to the inner wall of the frame 205, a positioning claw 206 slidably connected to the frame 205 via a sliding groove, the positioning claw 206 being connected to the spring 207, a sliding rod 208 fixedly connected to the positioning claw 206 and slidably connected to the frame 205, a transmission plate 209 rotatably mounted at the end of the sliding rod 208, a slot 210 provided on the transmission plate 209, and a limiting strip 211 corresponding to the slot 210 fixedly connected to the frame 205. Pulling the transmission plate 209 causes it to move from the limiting strip 211. Then rotate the transmission plate 209 to offset it from the limit bar 211, and then gradually release the transmission plate 209. The spring 207 pushes the positioning claw 206 to move towards the middle. The positioning claws 206 on both sides can clamp the component and fix it, which is convenient for subsequent processing of the component. After pulling the transmission plate 209 away from the limit bar 211, rotating it to offset it will release the tension of the spring 207, so that the positioning claws 206 on both sides can simultaneously and elastically clamp the component towards the middle under the action of the spring 207, which also has the function of elastic self-adaptive fit to the workpiece.

[0029] Furthermore, a handwheel 204 is fixedly connected to the top of the screw 202. The screw 202 is mounted on the frame through a nut seat. Turning the handwheel 204 can drive the screw 202 to rotate, which is convenient for the operator to operate.

[0030] The inner surface of the positioning claw 206 is provided with a removable wear-resistant liner, which is made of alloy steel.

[0031] A control panel is installed on the workbench 100 to control the operation of the drive motor 301.

[0032] As can be seen from the embodiments, the component can be positioned from top to bottom, and the component can be clamped from both sides, which can adapt to the processing of the component in different environments.

[0033] Example 2:

[0034] Combination Figure 1 and Figure 4As shown, based on Embodiment 1, the adjustment mechanism 300 includes gear rings 302 respectively fixed to two supports 201. Two motors 301 are fixedly mounted on the worktable 100. The output end of the motor 301 is fixedly connected to a spur gear 303 that meshes with the corresponding gear ring 302. An annular groove is provided on the worktable 100. The support 201 is located in the annular groove and slidably connected to it. When the motor 301 starts, it drives the spur gear 303 to rotate. The rotation of the spur gear 303 drives the gear ring 302 to rotate. The frame moves with the gear ring 302 and stops moving when it reaches the position of the corresponding part. Then the positioning claw 206 can fix the part. The position of fixing the part can be adjusted. The motor 301 drives the spur gear 303 to rigidly mesh with the gear ring 302, driving the support 201 to slide freely 360° along the annular groove. The rotation angle and position can be precisely controlled by the program. It can quickly switch to any preset positioning point without manual intervention, which significantly improves the positioning efficiency of multi-specification parts or complex processes.

[0035] The dual motors 301 independently drive the dual brackets 201, supporting synchronous or asynchronous adjustment (such as adjusting the angle between the two positioning claws 206), and are compatible with asymmetrical components such as triangles and trapezoids, solving the problem of high tooling costs for traditional platforms with "one machine, one type".

[0036] As can be seen from the above embodiments: First, according to the positional requirements of the component to be assembled, the motor 301 of the adjustment mechanism 300 is started via the control panel. The spur gear 303 at the output end of the motor 301 rotates and meshes to drive the gear ring 302 fixed to the bracket 201, causing the bracket 201 to slide along the annular groove on the worktable 100 to the corresponding position and then stop. Next, the handwheel 204 at the top of the screw 202 is rotated, and the rotation of the screw 202 drives the threaded sleeve 203 to move downward. The bottom end of the sleeve 203 is fixed to the frame. The body 205 moves down, and the positioning claws 206 on the frame 205 contact and fix the component. If it is necessary to fix the component from both sides, the transmission plate 209 needs to be pulled to disengage it from the limiting strip 211 of the frame 205. After the transmission plate 209 is rotated to disengage from the limiting strip 211, it is released. The spring 207 on the inner wall of the frame 205 pushes the positioning claws 206 connected to the slide rod 208 to move along the slide groove towards the middle. The positioning claws 206 on both sides clamp the component from the side to achieve fixation and provide stable clamping.
