DETAILED DESCRIPTION

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0026] Reference Figures 1 to 4 The utility model discloses a car gearbox disassembly and assembly workbench, which comprises a table top 1 supported by table legs. The table top 1 is divided into a lifting area 10, a disassembly and assembly area 11 and a parts storage area 12 in sequence along the length direction.

[0027] Among them, the lifting area 10 is used for assembling or disassembling the gearbox body 30 and the box cover 31, referring to Figure 1 The hoisting area 10 is provided with a hoisting mechanism 2, and the hoisting mechanism 20 includes a frame 20 erected on the table 1, and a winch 22 is installed on the top of the frame 20.

[0028] Reference Figure 1 A hanger 21 that can slide up and down is provided on the frame 20. The top of the hanger 21 is connected to the wire rope of the winch 22. The winch 22 can drive the hanger 21 to rise and fall on the frame 20; the lower end of the hanger 21 is connected to the box cover 31 through a number of suspension rods 210.

[0029] Specifically, in fact, there is a lifting hole on each of the left and right sides of the top of the box cover 30, and four groups of lifting rods 210 are provided at the bottom of the hanger 21. The upper ends of the four groups of lifting rods 210 pass through the hanger 21, and the upper end of the hanger 21 is provided with a locking plate 211 threadedly connected to the upper end of the lifting rod 210, so that the upper end of the lifting rod 210 can be fixed on the hanger 21, and a pin 212 is provided between the two groups of lifting rods 210 on the same side, and the pin 212 is passed through the lifting hole at the top of the box cover 31; due to the sliding fit relationship between the frame 20 and the hanger 21, after the gearbox body 30 is placed at the specified position of the lifting area 10, the box cover 31 can be accurately aligned with the gearbox body 30 up and down.

[0030] Correspondingly, the table surface 1 of the hoisting area 10 has corresponding positioning protrusions to align the gearbox body 30 and the box cover 31 vertically.

[0031] Reference Figure 1 After the box cover 31 is lifted, in order to avoid long-term strain on the winch 22, support plates 23 are slidably provided on both sides of the frame 20. The support plates 23 can move horizontally and support the bottom of the lifted box cover 31. When lifting, it is only necessary to pull the support plates 23 away from the bottom of the box cover 31.

[0032] In addition, refer to Figure 2 The hoisting area 10 and the disassembly area 11 are connected by a slide 4. The gearbox body 30 is slidably set on the slide 4. Under the push of external force, the gearbox body 30 can be moved to the disassembly area 11 after the box cover 31 is removed. The table 1 of the disassembly area 11 is wider than that of the hoisting area 10, which is conducive to the disassembly and assembly of the gears inside the gearbox body 10.

[0033] Among them, reference Figure 2 In this embodiment, the slide 4 includes a slide 41 protruding from the table 1, a sliding plate 40 is slidably provided on the slide 41, and the lower end of the gearbox body 30 is fixed to the sliding plate 40 by bolts.

[0034] In order to facilitate students to disassemble and observe the gear transmission structure inside the gearbox body 30, a group of circular support positions are provided in the middle of the slide 41 on the disassembly and assembly area 11, and a group of turntables 5 are provided in the support positions. When the gearbox body 30 moves to the disassembly and assembly area 11, the turntable 5 is lifted up by the lifting mechanism 6, so that the lower end of the sliding plate 40 is separated from the slide 41, and the gearbox body 30 can be easily rotated, which is convenient for disassembly and observation and learning.

[0035] As for the arrangement of the lifting mechanism 6 , it is well known to those skilled in the art that a hydraulic cylinder, a pneumatic cylinder or an electric cylinder can be used to drive the lifting.

[0036] In one embodiment, referring to Figure 3 and Figure 4A lifting mechanism 6 is provided below the disassembly and assembly area 11 , and the upper end of the lifting mechanism 6 is rotatably connected to the turntable 5 .

[0037] Among them, the jacking mechanism 6 includes a group of bidirectional screw pairs and a support plate 64. The bidirectional screw pair includes a bidirectional screw 60 horizontally arranged below the table 1. The two ends of the bidirectional screw 60 are rotatably connected to the connecting seat 62 located on the bottom of the table 1. The threads at both ends of the bidirectional screw 60 rotate in opposite directions, and two groups of sliders 61 are threadedly connected to the bidirectional screw 60. The sliders 61 can be horizontally slidably embedded in the lower end surface of the table 1. By rotating the bidirectional screw 60, the two groups of sliders 61 can be driven to expand or gather.

[0038] Reference Figure 3 and Figure 4 The opposite surfaces of the two sets of sliders 61 both have wedge-shaped surfaces 610. The bottom of the support plate 64 is in sliding contact with the two sets of sliders 61. The upper end of the support plate 64 is rotatably connected to the bottom of the turntable 5. By rotating the bidirectional screw rod 60, the support plate 64 can be driven to rise and fall.

[0039] In addition, one end of the bidirectional screw rod 60 extends to the outside of the table 1, and a hand wheel 63 or a force rod is provided at the end to facilitate manual driving of the turntable 5 to rise and fall.

[0040] In addition, in some embodiments, the table top 1 also has a parts storage area 12 for storing gears. Several vertical plates are linearly arranged in the parts storage area 12. There is a gap 121 for storing gears between any two adjacent groups of vertical plates, and arc grooves 120 for supporting the gear shaft are relatively opened on the vertical plates on both sides of the gap 121.

[0041] The working principle of this utility model is as follows:

[0042] When disassembling the box cover 31 , it is only necessary to remove the bolts between the box cover 31 and the gearbox body 30 , lift the box cover 31 using the winch 22 and the hanger 21 , and then push the support plate 23 to support the bottom of the box cover 31 .

[0043] When disassembling the gearbox body 30, the gearbox body 30 is pushed to the disassembly area 11. If the gearbox body 30 needs to be rotated, the turntable 5 only needs to be lifted up by the lifting mechanism 6. The gearbox body 30 is supported by the turntable 5 and can be easily rotated.

[0044] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
