DETAILED DESCRIPTION

[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the preferred embodiments of the present invention, rather than all the embodiments. It should be understood by those skilled in the art that these implementation methods are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0023] Example 1: Please refer to Figure 1-3 ;

[0024] The utility model provides the following technical solutions: a motor spindle transfer device, comprising a square box 1 with four sides, front, back, left and right, wherein a detachable box cover 2 is provided at the upper open end of the square box 1; further comprising two screws 3, respectively located on the outer sides of the left and right side walls of the square box 1; the screws 3 are rotatably connected to the square box 1; a pair of sliding sleeves 4 are sleeved on each of the screws 3; a plug 41 is provided on one side of the sliding sleeve 4, and the plug 41 is inserted into a preset sliding groove 11 on the outer wall of the square box 1, and is used to drive a pair of the sliding sleeves 4 to close or open when the screw 3 rotates; the upper end of the sliding sleeve 4 is hinged to the lower end of the connecting rod 5, and the two corresponding ones of the pair of sliding sleeves 4 are The upper end of the connecting rod 5 is coaxially hinged on the round rod 51, and the upper end of the hanging basket 6 that can be inserted into the square box 1 is hung on the round rod 51, which is used to drive the hanging basket 6 to rise or fall from the square box 1 when a pair of the sliding sleeves 4 are closed or opened; the driving shaft 7 is located on the outer side of the front side wall of the square box 1 in a horizontal posture, and is rotatably connected to the square box 1, and worm sections 71 are provided at both ends of the worm section 71. The worm section 71 is meshed and connected with the worm wheel 31 fixed at the end of the screw 3, and is used to drive the two screws 3 to rotate synchronously when the driving shaft 7 rotates; screwing heads 72 are fixed at both ends of the driving shaft 7, which are used to connect a screwing tool to drive the driving shaft 7 to rotate.

[0025] The working principle includes that there is only a hanging basket 6 inside the square box 1, without too many moving parts, and its side wall is not nailed or perforated, and it is a closed container, and sealing oil is injected into the square box 1. When the hanging basket 6 falls into the square box 1, the space occupied in the square box 1 forces the oil level to rise, and the motor main shaft in the square box 1 is sealed. The principle of the driving mechanism is that when the driving shaft 7 rotates, the worm segments 71 at both ends rotate, driving the worm wheel 31 to rotate, the worm wheel 31 drives the screw 3 to rotate, the screw 3 drives a pair of sliding sleeves 4 to translate, and the pair of sliding sleeves 4 drives a pair of connecting rods 5. When the two pairs of sliding sleeves 4 are closed at the same time, the top ends of the two pairs of connecting rods 5 rise, driving the hanging basket 6 to rise. Thereby, the motor main shaft in the hanging basket 6 is kept away from the oil level. At this time, since the screw 3 and the sliding sleeve 4, as well as the worm wheel 31 and the worm have the function of self-locking the thread, the hanging basket 6 can be suspended at the upper end of the square box 1 without the help of external power, thereby playing the role of draining the sealing oil in the hanging basket 6, so the device has an automatic draining function.

[0026] The hanging basket 6 can be made of steel wire braiding, which is permeable and convenient for the sealing oil to enter and exit. At least, dense through holes 61 are provided on the bottom plate of the hanging basket 6. Of course, the side wall of the hanging basket 6 can also be densely covered with through holes 61.

[0027] It can be seen that the pair of the sliding sleeves 4 are provided with screw holes with opposite spiral directions, and the screw rod 3 passes through the two screw holes, which are used to drive the pair of the sliding sleeves 4 to close or open when the screw rod 3 rotates. The screw holes are threadedly connected with the screw rod 3 to form a screw slider mechanism, wherein the plug 41 of the sliding sleeve 4 is inserted into the sliding groove 11, which can limit the radial freedom of the sliding sleeve 4 and only retain its axial sliding ability.

[0028] In order to allow the hanging basket 6 to completely fall into the box 1, the upper ends of the left and right side walls of the box 1 are provided with first notches 12, which correspond to the positions of the round rods 51 and are used to prevent the round rods 51 from interfering with the side walls of the box 1 when the hanging basket 6 completely falls into the box 1. It can be seen that when the hanging basket 6 falls into the box 1, the oil level rises, the sealing parts, and the notches do not need to be sealed.

[0029] In order to prevent dust accumulation, the left and right side walls of the box cover 2 are provided with second notches 21, which correspond to the positions of the round rods 51, and are used to prevent the round rods 51 from interfering with the side walls of the box cover 2 when the box cover 2 is buckled on the upper end of the square box 1. It can be seen that after the hanging basket 6 falls into the square box 1, the box cover 2 can also be covered, which has better sealing performance and prevents dust from falling.

[0030] In order to more conveniently grasp the box cover 2 , a handle 22 is fixedly provided on the upper end of the box cover 2 .

[0031] A better option is to Figure 3As shown, the lower part of the opposite side walls of the square box 1 is provided with an oil pipe joint 13 for filling and discharging sealing oil into the square box 1. At this time, a plurality of square boxes 1 can be connected in series by a connecting pipe 14, and the oil pipe joint 13 of one of the square boxes 1 is connected to a refueling device 15. By using the communicating vessel principle, the oil level height of each square box 1 is the same, and sealing oil can be filled and discharged into a plurality of square boxes 1 at the same time, thereby improving efficiency.

[0032] When in use, first, the box cover 2 is in a dismantled state, and a screwing tool, such as an electric wrench, is used to drive the drive shaft 7 to rotate by connecting the screw head 72, thereby driving the screw 3 to rotate, and the screw 3 drives the sliding sleeve 4 to close, and the connecting rod 5 lifts the hanging basket 6. At this time, the motor spindles can be placed in the hanging basket 6 one by one. When the hanging basket 6 is full of motor spindles, the drive shaft 7 is reversed, and the hanging basket 6 falls into the square box 1. The oil level rises to isolate the air, thereby preventing the motor spindle from rusting after processing. Then, the box cover 2 is covered, and it is transferred to a designated location together with the square box 1. It can be stored for a long time with oil seal storage and will not rust. When the motor spindle needs to be taken, the box cover 2 is opened, the drive shaft 7 is reversed, and the hanging basket 6 is driven to rise and away from the oil level. By using the self-locking thread, the hanging basket 6 can be suspended at the upper end of the square box 1 without the help of external power, thereby draining the sealing oil in the hanging basket 6. Then, the motor spindle is taken out for processing in the next process. The advantages of this embodiment are that, compared with the prior art:

[0033] (1) The box cover 2 is removable to prevent dust accumulation, and the hanging basket 6 can be raised and lowered to facilitate the storage and access of the motor spindle.

[0034] (2) Through the self-locking of the threads, the hanging basket 6 can be suspended above the square box 1, thereby automatically draining the sealing oil in the hanging basket 6, which is convenient to use.

[0035] (3) The hanging basket 6 filled with the motor main shaft occupies a relatively small volume, so there is no need to inject too much sealing oil into the square box 1, saving costs.

[0036] (4) The device and the sealing oil can be reused, and the cost of use is low.

[0037] In summary, this embodiment utilizes oil immersion to isolate the air, can be stored for a long time, overcomes the problem that the motor shaft is prone to rust, and is easy to store and access and can be reused.
