For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Example 1

[0027] See also Figure 1-4 A pre-assembled workbench for an air compressor comprises a workbench plate 1, on which two groups of fixing components are symmetrically arranged, and the fixing components comprise a moving seat 2 and two relatively arranged fixing clamps 3, the moving seat 2 is connected to the workbench plate 1 through a transverse translation component, and two fixing clamps 3 are relatively provided with V-shaped fixing grooves, and the fixing clamps 3 are connected to the moving seat 2 through a longitudinal translation component.

[0028] The two groups of fixing components are respectively used to fix the two ends of the air compressor. When in use, first adjust the distance between the two groups of fixing components through the lateral translation component according to the lateral size (axis length) of the air compressor, and then adjust the distance between the two fixing clamps 3 in each group of fixing components through the longitudinal translation component according to the longitudinal size (outer diameter) of the air compressor, so that the fixing clamps 3 clamp the air compressor.

[0029] It should be noted that before fixing the air compressor, the air compressor can be moved between the two fixing clamps of the fixing assembly in advance, and supported by pads or the like, or hoisted by a hoist; when fixing the air compressor, pay attention to the relative position of the fixing clamp 3 and the air compressor, and reserve the pre-installation position of the air compressor to facilitate the pre-installation operation.

[0030] The transverse translation assembly includes a transverse threaded rod 4 and a transverse guide rod 5. The transverse threaded rod 4 is rotatably connected to the work table 1. The transverse threaded rod 4 is symmetrically provided with two opposite external threads and is connected to a transverse translation motor. The transverse guide rod 5 is fixed to the work table 1. The moving seat 2 is provided with an internal threaded hole and a guide hole that slides with the guide rod. The internal threaded holes of the two moving seats 2 are respectively matched with the two external threaded holes on the transverse threaded rod 4.

[0031] The lateral translation motor drives the lateral threaded rod 4 to rotate forward and reversely, and can drive the two moving seats 2 to move toward or away from each other, thereby realizing the lateral translation of the fixed component; the lateral guide rod 5 is used to provide guidance for the lateral translation of the fixed component.

[0032] The movable seat 2 is provided with a slide groove extending in the longitudinal direction, and the fixed clamping block is connected to a slider 6 that slides with the slide groove, and the slider 6 is provided with two internal threaded holes. The longitudinal translation assembly includes a longitudinal threaded rod 7 and a driving rod 8. The longitudinal threaded rod 7 is rotatably connected in the slide groove, and the longitudinal threaded rod 7 is symmetrically provided with two opposite external threads and connected with a transmission worm gear 9. The two internal threaded holes on the two sliders 6 respectively match the two external threads on the longitudinal threaded rod 7. The driving rod 8 is parallel to the transverse threaded rod 4 and is connected with a longitudinal translation motor. The driving rod is provided with a key groove extending along its axial direction. The driving rod 8 is connected with a transmission worm 10 corresponding to the transmission worm gear 9 of each movable seat 2, and the transmission worm 10 is meshed with the transmission worm gear 9 and sleeved on the driving rod 8. The transmission worm gear 9 is provided with a connecting key 11 that matches the key groove. Limiting plates 12 are provided on both sides of the transmission worm 10, and the limiting plates 12 are provided with through holes for the driving rod 8 to pass through, and the limiting plates are connected to the movable seat 2.

[0033] The longitudinal translation motor drives the driving rod 8 to rotate forward and reversely. The transmission worm 10 rotates synchronously with the driving rod 8 under the action of the connecting key 1, and drives the longitudinal threaded rod 7 to rotate through the transmission worm wheel 9, thereby realizing the longitudinal translation of the fixed clamp block.

[0034] When the movable seat 2 is translated laterally, the movable seat 2 drives the transmission worm 10 to move synchronously along the axial direction of the driving rod 8 through the limit plate 12, so that the transmission worm wheel 9 and the transmission worm 10 always maintain a meshing state, which will not affect the transmission between the driving rod 8 and the longitudinal threaded rod 7.

[0035] This embodiment realizes the simultaneous clamping and fixing of the air compressor by two fixing components by setting a driving rod, which not only simplifies the structure but also ensures the consistency of the clamping force of the two fixing components.

[0036] Example 2

[0037] See also Figure 5-6 The difference between this embodiment and embodiment 1 is that: the workbench is connected to the frame through an angle adjustment component, and the angle adjustment component includes a drive shaft 13, a horizontal shaft 14, and a vertical shaft 15. The drive shaft 13 is rotatably connected to the frame and is connected to an angle adjustment motor. The drive shaft 13 is connected to a bevel gear 1, and the horizontal shaft 14 is rotatably connected to a U-shaped frame 16 and is connected to a bevel gear 2 meshing with the bevel gear 1. The workbench is connected to the horizontal shaft 14 through a connecting ear plate 17, and the U-shaped frame 16 is connected to the vertical shaft 15. The vertical shaft 15 is hollow and coaxially arranged on the outside of the drive shaft 13. The vertical shaft 15 is rotatably connected to the frame, and a clutch assembly is provided between the vertical shaft 15 and the drive shaft 13.

[0038] In this embodiment, the driving shaft 13 passes through the vertical rotating shaft 15 and is connected to the U-shaped frame 16 .

[0039] The angle of the worktable can be adjusted around the horizontal rotating shaft 14 or the vertical rotating shaft 15 through the angle adjustment component, so that the pre-installed position of the air compressor can be rotated to a direction convenient for the staff to operate, so as to reduce the walking of the staff and improve the convenience of operation.

[0040] The clutch assembly is used to achieve the clutch between the vertical rotating shaft 15 and the driving shaft 13, and to switch whether the vertical rotating shaft 15 rotates synchronously with the driving shaft 13, so as to cooperate with other components to realize the angle adjustment of the working table and the air compressor around the horizontal rotating shaft 14 or the vertical rotating shaft. The specific working principle is: when the vertical rotating shaft 15 and the driving shaft 13 rotate asynchronously, the angle adjustment motor drives the driving shaft 13 to rotate, and under the meshing action of bevel gear one and bevel gear two, the horizontal rotating shaft 14 rotates, thereby adjusting the angle of the fixed table and the air compressor around the horizontal rotating shaft 14; when the vertical rotating shaft 15 and the driving shaft 13 rotate synchronously, the U-shaped frame 16, the horizontal rotating shaft 14, the bevel gear one, and the bevel gear two all rotate synchronously with the driving shaft 13, and the bevel gear one and the bevel gear two do not mesh. Therefore, at this time, the horizontal rotating shaft does not rotate by itself, and the angle of the working table and the air compressor around the vertical rotating shaft 15 can be adjusted.

[0041] One end face of the vertical shaft is provided with meshing teeth arranged in an annular manner, and the drive shaft 13 is provided with keyways extending along its axial direction. The clutch assembly includes a clutch sleeve 18 and a lifting ring 19. The clutch sleeve 18 is sleeved on the outside of the drive shaft, and one end face of the clutch sleeve 18 is provided with meshing teeth arranged in an annular manner and meshing with the meshing teeth one. The inner wall of the clutch sleeve 18 is provided with connecting keys 20 matching the keyways two. The clutch sleeve 18 is provided with two limit stops 21 in the vertical direction. The lifting ring 19 is sleeved on the outside of the clutch sleeve and is located between the two limit stops 21. The lifting ring 19 is connected to the frame through a lifting and telescopic device 22.

[0042] The lifting and telescopic equipment can use an electric telescopic rod in the prior art.

[0043] When the lifting and telescopic device is started, the lifting ring 19 can be lifted and lowered. The lifting ring 19 drives the clutch sleeve 18 to lift and lower synchronously through the limit stopper 21, so that the clutch sleeve 18 can be switched between high and low positions, thereby realizing the clutch switching of the vertical shaft 15 and the drive shaft 13. Specifically, when the clutch sleeve 18 is in a high position, the meshing teeth 2 thereon mesh with the meshing teeth 1 on the vertical shaft 15. When the drive shaft 13 rotates, the clutch sleeve 18 is driven to rotate synchronously through the connecting key 2, and the vertical shaft 15 rotates with the clutch sleeve 18; when the clutch sleeve 18 is in a low position, the meshing teeth 2 thereon do not mesh with the meshing teeth 1 on the vertical shaft 15. When the drive shaft 13 rotates, the clutch sleeve 18 rotates, and the vertical shaft 15 no longer rotates.

[0044] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
