A new energy reducer housing leveling mechanism

Abstract

This utility model discloses a leveling mechanism for the housing of a new energy reducer, relating to the field of testing equipment. The mechanism includes a base plate with a clearance groove in the middle. A top support frame is fixed to the top surface of the base plate, and three lifting devices are mounted on the top support frame. Each lifting device has a contouring component at its moving end. This mechanism can determine whether the top surface of the housing is level with the horizontal detection block by measuring changes in air pressure, thus effectively detecting the levelness of the housing's top surface. Furthermore, by combining this with a corresponding clamp to drive the top surface of the housing to tightly press against the bottom surface of the horizontal detection block, the clamping pressure is reasonably controlled, avoiding situations where the clamping is too loose, resulting in insufficient contact, or too tight, causing damage to the housing. This improves the stability and accuracy of the testing.

Description

Technical Field

[0001] This utility model relates to the field of testing equipment, and in particular to a mechanism for inspecting and leveling the housing of a new energy reducer. Background Technology

[0002] In the field of flatness inspection of new energy reducer housings, traditional inspection methods have certain limitations: positioning relies heavily on the outer contour, which is difficult to match precisely with the internal structure of the housing, often resulting in inspection errors due to inaccurate positioning; during clamping, poor control of contact pressure either results in the housing not fitting tightly to the inspection reference surface due to excessively loose clamping, or damage to the housing due to excessively tight clamping; when judging flatness, manual visual observation lacks objective basis, resulting in low accuracy and reliability, which seriously affects the quality and efficiency of inspection and makes it difficult to meet the needs of large-scale production. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a new energy reducer housing leveling mechanism, which solves the problems of inaccurate positioning, uncontrolled clamping pressure, and low reliability of manual judgment in traditional testing.

[0004] To address the problems in the existing technology, the technical solution of this utility model is as follows: A new energy reducer housing leveling mechanism includes a base plate, a clearance groove in the middle of the base plate, a top support frame fixed on the top surface of the base plate, and multiple lifting devices on the top support frame. Each lifting device has a contouring part at its moving end, which is a component that simulates a part installed inside the reducer housing. The base plate is provided with multiple horizontal detection blocks surrounding the clearance groove. The bottom surface of the horizontal detection blocks is provided with a horizontal detection component to detect the horizontality of the top surface of the reducer housing. The base plate is provided with multiple clamps, each clamp facing a horizontal detection block.

[0005] Optionally, the lifting device has three parts, and the three contouring parts respectively simulate the input shaft, intermediate shaft and differential installed in the reducer housing. The reducer housing has mounting positions that match the three contouring parts one by one. The relative positions of the contouring parts and the reducer housing are respectively matched with the positions of the input shaft, intermediate shaft and differential simulated by the contouring parts installed in the reducer housing.

[0006] Optionally, the horizontal detection component includes an air extraction port on the bottom surface of the horizontal detection block, the bottom surface of the horizontal detection block is planar, and the side wall of the horizontal detection block is provided with an air nozzle communicating with the air extraction port.

[0007] Optionally, the clamp includes a cylinder fixed to the base plate, the cylinder is vertically downward, and a clamping bar is rotatably connected to the end of the piston rod of the cylinder. The clamping bar is directly opposite the corresponding horizontal detection block. Two connecting rods are symmetrically rotatably connected to the end of the clamping bar near the horizontal detection block. The upper ends of the two connecting rods are rotatably connected to the base plate.

[0008] Optionally, a positioning port is provided on the top surface of the clamping strip near the horizontal detection block. A pin is inserted into the positioning port, and a hard rubber block is formed on the top of the pin. The pin and the hard rubber block are integrally constructed. A threaded hole is provided at the end of the clamping strip away from the cylinder. A bolt is threaded into the threaded hole, and the end of the bolt extends into the positioning port and abuts against the outer wall of the pin.

[0009] Compared with the prior art, the advantages of this utility model are as follows: 1. This utility model achieves precise positioning of the reducer housing by arranging three lifting devices and contouring parts on the top support frame. The contouring parts mimic the internal components of the reducer and match their relative positions with the reducer housing, thus solving the problem of inaccurate positioning relying on the outer contour in traditional testing. At the same time, multiple horizontal detection blocks are arranged around the clearance groove. With the arrangement of air nozzles, negative pressure pumps, and air pressure gauges, changes in air pressure can be used to determine whether the top surface of the housing is level with the horizontal detection blocks, thus achieving effective detection of the levelness of the top surface of the housing. Furthermore, the corresponding clamps drive the top surface of the housing to tightly press against the bottom surface of the horizontal detection blocks, reasonably controlling the clamping pressure and avoiding situations where the clamping is too loose, resulting in an incomplete fit, or too tight, causing damage to the housing, thereby improving the stability and accuracy of the test. 2. This utility model uses the arrangement of connecting all air nozzles to a negative pressure pump and installing air pressure gauges on the connecting pipelines to determine whether the top surface of the reducer housing is flat by using air pressure changes. This replaces the traditional manual visual observation and achieves an objective and accurate judgment of the flatness of the top surface of the housing, greatly improving the accuracy and efficiency of the test and better meeting the needs of large-scale production.

[0010] 3. This utility model inserts a pin with a hard rubber block into the positioning hole of the clamping strip, and fixes the arrangement of the pin with bolts. The hard rubber block directly contacts the reducer housing, avoiding hard contact between the clamping strip and the outer wall of the housing, thus effectively protecting the reducer housing. At the same time, this structural design makes it easy to replace the hard rubber block after it wears out, ensuring the reliability and clamping effect of the fixture for long-term use.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1 to 5 This embodiment provides a new energy reducer housing leveling mechanism, including a base plate 1, a clearance groove 101 in the middle of the base plate 1, a top support frame 2 fixed on the top surface of the base plate 1, and three lifting devices 3 on the top support frame 2. Each lifting device 3 has a contouring part 4 at its moving end. The lifting device 3 can be a cylinder 7 or a linear push rod or other linear lifting motion standard parts. The contouring part 4 imitates the internal parts of the reducer, and the relative position of the contouring part 4 and the reducer housing matches the position of the internal parts of the reducer housing installed inside the reducer housing.

[0019] Three contouring parts 4 correspond to the input shaft, intermediate shaft, and differential, respectively, which are installed inside the reducer housing. The reducer housing has pre-set mounting positions (such as input shaft bearing holes, intermediate shaft shoulder locating surfaces, and differential mounting cavities) that match each of these components. The shape and dimensions of each contouring part 4 are identical to the corresponding input shaft, intermediate shaft, and differential, and their relative positions to the reducer housing perfectly match the actual positions of the input shaft, intermediate shaft, and differential when installed inside the reducer housing. During testing, the three contouring parts 4 are inserted into their corresponding mounting positions within the reducer housing, and the precise fit between them and their corresponding mounting positions achieves the correct positioning of the reducer housing.

[0020] Multiple horizontal detection blocks 5 are arranged around the clearance groove 101 on the base plate 1. The bottom surface of the horizontal detection block 5 is flat and has an air extraction port 501. An air nozzle 6 is provided on the side wall of the horizontal detection block 5 and is connected to the air extraction port 501. A clamp is provided on the base plate 1 directly opposite each horizontal detection block 5. The reducer housing is placed below the base plate 1, and three contour pieces 4 are inserted into the reducer housing at the corresponding positions to position the reducer housing. The top surface of the reducer housing abuts against the bottom surface of the multiple horizontal detection blocks 5. Then, all the clamps are driven to work, clamping the reducer housing so that its top surface is pressed against the bottom surface of the horizontal detection block 5.

[0021] All air nozzles 6 are connected to a negative pressure pump for suction, and a pressure gauge is installed on the connecting pipe between the negative pressure pump and the air nozzle 6. If the part of the reducer housing that touches the horizontal detection block 5 is horizontal, no external air will enter the air extraction port, and the pressure gauge will show the set normal value. Otherwise, the pressure gauge will show a non-set normal value, indicating that there is a non-horizontal position on the top surface of the reducer housing. By observing the value displayed on the pressure gauge, it can be determined whether the top surface of the reducer housing at the horizontal detection block 5 is flat.

[0022] The clamp includes a cylinder 7 fixed on the base plate 1, with the cylinder 7 facing vertically downwards. The end of the piston rod 701 of the cylinder 7 is rotatably connected to a clamping strip 8 via a pivot pin. The clamping strip 8 is directly opposite a horizontal detection block 5. The end of the clamping strip 8 near the horizontal detection block 5 is symmetrically connected to two connecting rods 9 via pivot pins. The upper ends of the two connecting rods 9 are rotatably connected to the base plate 1 via pivot pins. When the reducer housing is removed, the cylinder 7 retracts, pulling the clamping strip 8 to flip, so that the clamping strip 8 moves away from the horizontal detection block 5. Then the reducer housing can be removed or the reducer housing can be put down. When the reducer housing is positioned and clamped against multiple horizontal detection blocks 5, the cylinder 7 extends, pushing the clamping strip 8 close to the horizontal detection block 5 to clamp the reducer housing against the bottom surface of the horizontal detection block 5.

[0023] A positioning port 801 is provided on the top surface of the clamping strip 8 near the horizontal detection block 5. A pin part 1001 is inserted into the positioning port 801. A flat hard rubber block 10 is formed on the top of the pin part 1001. The pin part 1001 and the hard rubber block 10 are integrally constructed. The bottom surface of the hard rubber block 10 is in contact with the top surface of the clamping strip 8. A threaded hole 11 is provided at the end of the clamping strip 8 away from the cylinder 7. The axis of the threaded hole 11 is perpendicular to the longitudinal side wall of the pin part 1001. A bolt 12 is threaded into the threaded hole 11. The end of the bolt 12 extends into the positioning port 801 and abuts against the outer wall of the pin part 1001. In this way, when clamping the reducer housing, the clamping strip 8 can avoid hard contact with its outer wall, protecting the reducer housing and facilitating the replacement of the hard rubber block 10.
