Description

Technical Field

[0001] This utility model relates to the field of equipment technology for processing gearbox housings, and in particular to an assembly platform that facilitates the assembly of gearbox housings. Background Technology

[0002] The gearbox housing is mainly used to support and fix the shaft assembly, ensuring the operating accuracy, lubrication, and sealing performance of the transmission system. Its structural design directly affects the gearbox's working performance, production cost, and manufacturing difficulty. The housing is commonly made of gray cast iron, which has excellent vibration damping performance and casting adaptability. For heavy-load or impact conditions, cast steel can be used, and it can also be welded from steel plates for single-piece production. Gearbox housings come in various types, such as split, combined, and integral types. Split gearbox housings consist of a lower housing and an upper housing. The lower housing, as the basic load-bearing part, is usually an integrally cast or welded structure. It has a mounting base at the bottom (for fixing to the equipment frame) and internally machined bearing seats for shaft support, lubricating oil grooves / sumps (for gear and bearing lubrication), and locating pins. Holes and connecting bolt holes; Upper housing: As the cover, it cooperates with the lower housing to form a closed space. The interior is also machined with bearing seat holes (coaxial with the holes in the lower housing to jointly support the shaft system), observation window (for checking the internal transmission), vent holes (to balance the air pressure in the housing), etc. The top may be equipped with lifting rings (for easy hoisting). When assembling the reducer, the bearings, gears, retaining rings and other components must first be pre-assembled with the shaft system (input shaft, intermediate shaft, output shaft), then the shaft system (input shaft, intermediate shaft, output shaft) is installed in the lower housing, and finally the upper housing is placed on the lower housing to complete the installation of the entire reducer.

[0003] However, in the existing technology, when assembling the upper and lower boxes, it is necessary to manually control the crane (or hoisting tool) to lift the upper box smoothly, adjust its height to a position above the lower box, ensure that the split surface of the upper box is parallel to the lower box, and then control the upper box to move down to the surface of the lower box. This increases the workload of the workers and reduces the efficiency of assembly, which needs to be further improved. Utility Model Content

[0031] The following is in conjunction with the appendix Figure 1-7 The present invention will provide a more detailed description of an assembly platform for facilitating the assembly of a reducer housing.

[0032] An assembly platform that facilitates the assembly of gearbox housings, such as Figure 1 , 2 As shown, the system includes a support component 1, which comprises two elongated plates 11. A fixing plate 12 is horizontally installed between the two elongated plates 11. The two elongated plates 11 and the fixing plate 12 are integrally formed. The length of the two elongated plates 11 is greater than the length of the fixing plate 12. The lower box is placed on the top surface of the fixing plate 12. Support blocks 13 are vertically installed at the bottom corners of the two elongated plates 11. The four support blocks 13 provide support for the support component 1. When using the assembly platform, the support component 1 is pre-installed in a pre-set position.

[0033] In this embodiment, a first clamping block 3 is installed on the top surface of the fixing plate 12. There are three first clamping blocks 3. The lower box is placed between the three first clamping blocks 3. The three first clamping blocks 3 have the function of limiting and positioning the lower box, ensuring that the lower box is in a pre-set position.

[0034] In this embodiment, a sliding frame 2 is slidably connected along the length of the top surface of two long strips 11. The sliding frame 2 is U-shaped. A first drive assembly 5 is provided on the bottom surface of one of the long strips 11. The first drive assembly 5 drives the sliding frame 2 to move horizontally in an electric manner. The first drive assembly 5 includes a first servo motor 54, which is horizontally mounted inside one of the support blocks 13. A lead screw 52 is mounted on the output shaft of the first servo motor 54 through a coupling 55. The other end of the lead screw 52 is rotatably connected to the support block 13 opposite to the first servo motor 54. A drive guide block 53 is threadedly connected to the lead screw 52. The top surface of the drive guide block 53 is fixed to the sliding frame 2. A first strip-shaped hole 110 is provided on the top surface of the long strip 11 for the drive guide block 53 to slide. When the first servo motor 54 is started, the output shaft of the first servo motor 54 drives the lead screw 52 to rotate. The lead screw 52 drives the drive guide block 53 to move linearly. The drive guide block 53 drives the sliding frame 2 to move linearly.

[0035] In this embodiment, reference is made to Figures 6-7 A first guide rod 113 is horizontally installed between the other two support blocks 13. The guide rod is parallel to the lead screw 52. A first guide block 114 is slidably connected to the first guide rod 113. The first guide block 114 slides along the length of the first guide rod 113. A second strip hole 115 is opened horizontally on the top surface of the long plate 11 for the guide block to slide. The first strip hole 110 and the second strip hole 115 are symmetrically arranged. The top surfaces of the first guide rod 113 and the drive guide block 53 are fixed to the sliding frame 2. The first guide rod 113 drives the sliding frame 2 to slide along the axial direction of the first guide rod 113. The first guide block 114 guides the linear movement of the sliding frame 2.

[0036] In this embodiment, two movable frames 7 are slidably connected to the bottom surface of the sliding frame 2 in a vertical direction. A second drive assembly 6 for driving the two movable frames 7 to move vertically is provided on the top surface of the sliding frame 2. The second drive assembly 6 includes a reducer 61, which is horizontally mounted on the top surface of the sliding frame 2. A second servo motor 62 is mounted on the input shaft of the reducer 61. Both sides of the second servo motor 62 are fixed to the sliding frame 2 by fixing strips. Two rotating shafts 63 are rotatably arranged on the sliding frame 2. The inner ends of the two rotating shafts 63 are respectively fixed to the two output shafts of the reducer 61. Two bearing seats are symmetrically mounted on the top surface of the sliding frame 2. The reducer 61 is located between the two bearing seats. Bearings are installed in both bearing seats. The two rotating shafts 63 are respectively installed in the two bearings. A winding wheel 64 is installed at the outer end of each of the two rotating shafts 63. (Refer to...) Figure 3 Two wire holes 20 are symmetrically opened on the top surface of the sliding frame 2. The reducer 61 is located between the two wire holes 20. A wire rope 65 is installed in each of the two wire holes 20, with one end fixed to the winding wheel 64 and the other end fixed to the moving frame 7.

[0037] The second servo motor 62 is started. The output shaft of the second servo motor 62 drives the input shaft of the reducer 61 to rotate. The two output shafts of the reducer 61 drive the two rotating shafts 63 to rotate. The two rotating shafts 63 drive the take-up reel 64 to rotate. When the take-up reel 64 rotates in the forward direction, the wire rope 65 is wound on the take-up reel 64. The wire rope 65 drives the moving frame 7 to move upward. When the take-up reel 64 rotates in the reverse direction, the wire rope 65 drives the moving frame 7 to move downward. The moving frame 7 is driven vertically by electric means, without the need for manual intervention by the staff, which saves time and effort.

[0038] Among them, reference Figure 4 A second guide rod 21 is vertically installed on each of the two inner side walls of the sliding frame 2. A second guide block 22 is slidably connected to each of the two second guide rods 21. The two second guide blocks 22 are fixed to the two movable frames 7 respectively. The second guide blocks 22 drive the movable frame 7 to slide along the length direction of the second guide rod 21. The two second guide blocks 22 have a guiding effect on the vertical movement of the movable frame 7.

[0039] In this embodiment, two hooks 8 are hinged to each of the two movable frames 7. The hooks 8 can be hooks. The vertical movement of the movable frame 7 drives the hooks to move vertically.

[0040] When assembling the upper and lower boxes, the worker first places the lower box between the three first clamping blocks 3, which position the lower box. Then, the upper box is placed between the two long strips 11. The first servo motor 54 is started, and the sliding frame 2 automatically slides to the top of the upper box. Then, the second servo motor 62 is started, and the moving frame 7 moves vertically close to the surface of the upper box. The worker hooks the four hooks 8 onto the lifting rings and repeats the above actions to complete the assembly of the upper and lower boxes electrically. This eliminates the need for manual operation and alignment of the upper and lower boxes, reducing the workload of the workers.

[0041] In this embodiment, reference is made to Figure 5 There are two movable frames 7, which are symmetrically arranged along the length of the sliding frame. Each movable frame 7 includes a first long column 71, which is horizontally arranged. A second long column 72 is vertically installed on the top surface of the first long column 71. The top of the second long column 72 is fixed to the bottom of the wire rope 65. The wire rope 65 drives the second long column 72 to move vertically, and the second long column 72 drives the first long column 71 to move vertically.

[0042] Among them, a reinforcing rod 73 is installed at an angle on the top surface of the first long column 71, with one end fixed to the second long column 72. The reinforcing rod 73 will improve the load-bearing capacity of the entire mobile frame 7.

[0043] In this embodiment, two proximity switches 9 are provided on one side of one of the long strips 11. The two proximity switches 9 are symmetrically arranged along the length of the long strips 11. Both proximity switches 9 are electrically connected to the first servo motor 54. When the proximity switch 9 detects the sliding frame 2, the sliding frame 2 stops moving.

[0044] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
