Description

Technical Field

[0001] The utility model relates to a machine pump auxiliary installation device, in particular to a clamping structure based on automatic alignment and a machine pump auxiliary installation device. Background Technique

[0002] A pump is a machine that transports fluids or increases the pressure of fluids. It transmits the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. Pumps are mainly used to transport liquids such as water, oil, acid-base solutions, emulsions, suspension liquids, and liquid metals, and can also transport liquid-gas mixtures and liquids containing suspended solids.

[0003] The pump needs to be stably connected to a suitable power source for safe use, such as a rotating power source like an electric motor. When installing the pump body and the power source, it is necessary to ensure that the rotating shafts of the two are on the same straight line and are in close contact with each other. Usually, measuring tools such as a spirit level are required to assist in the installation.

[0004] When using a spirit level to assist in the installation, since the spirit level can only detect whether the axis of the rotating shaft of the pump body and the axis of the rotating shaft of the power source are in the same plane and cannot measure whether they are on the same straight line; if a spirit level is used for measurement, it is very likely that the pump body and the power source will be misaligned during installation, resulting in a reduction in the working efficiency of the pump body and even damage to the pump body.

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0052] Please refer to Figures 1 to 8 , as an embodiment of the present invention, the clamping structure based on automatic alignment includes a panel 11;

[0053] A guide and clamping mechanism is provided on the panel 11, and two symmetrically arranged clamping rings 23 are connected to the guide and clamping mechanism, and the guide and clamping mechanism can drive the clamping rings 23 to approach or move away from each other.

[0054] In this embodiment, the guiding and clamping mechanism first drives the two clamping rings 23 away from each other. After the pump body to be butt - installed is placed on the panel 11, the guiding and clamping mechanism then drives the two clamping rings 23 closer to each other until the clamping rings 23 firmly clamp the rotating shaft of the pump body. At this time, the axis of the rotating shaft is in the same vertical plane as the center line of the panel 11 and parallel to each other. The center line of the panel 11 and the rotating shaft of the output end of the power source are also in the same vertical plane and parallel to each other, so that the rotating shaft of the pump body and the rotating shaft of the power source are in different positions in the same vertical plane and parallel to each other.

[0055] As a further solution of the present utility model, the guiding and clamping mechanism includes a stop rod 22 fixedly installed on the panel 11. A clamping sleeve 2201 is fixedly installed on the stop rod 22. A clamping column 2301 fixedly connected to the clamping ring 23 is slidably fitted in the clamping sleeve 2201, and a clamping spring 24 is fixedly installed in the clamping sleeve 2201.

[0056] In this embodiment, by an external force, the clamping ring 23 is gradually moved closer to the stop rod 22. The clamping ring 23 drives the clamping column 2301 to slide in the clamping sleeve 2201, and at this time the clamping spring 24 is compressed. When the pump body is placed on the panel 11, the external force is removed. Under the elastic force of the clamping spring 24, the clamping column 2301 drives the clamping ring 23 to gradually move away from the stop rod 22. After the two clamping rings 23 contact the rotating shaft of the pump body, the rotating shaft of the pump body is squeezed, so that the axis of the pump body is squeezed and aligned with the center line of the panel 11 in the same vertical plane and parallel to each other.

[0057] A machine - pump auxiliary installation device includes a base 1. A positioning frame 21 is provided at one end of the base 1, and a positioning ring 20 is fixedly installed on the positioning frame 21;

[0058] A displacement mechanism and a lifting mechanism for connecting with the panel 11 are provided on the base 1. The displacement mechanism can drive the panel 11 to approach the positioning ring 20 in the horizontal direction, and while the displacement mechanism operates, the lifting mechanism can drive the panel 11 to approach the positioning ring 20 in the vertical direction;

[0059] A positioning mechanism connected to the positioning frame 21 is also provided on the base 1. The positioning mechanism can control the stroke end point of the lifting mechanism.

[0060] In this embodiment, the positioning frame 21 is moved by the positioning mechanism to drive the positioning ring 20 to abut against the rotating shaft of the power source. After the positioning ring 20 abuts against the rotating shaft of the power source, the positioning mechanism will keep this position unchanged until the pump body and the power source are connected to each other. The positioning mechanism will determine the strokes of the subsequent lifting mechanism and the displacement mechanism, and the end of the stroke is the correct position for the butt - joint of the pump body and the power source.

[0061] After the guiding and clamping mechanism stably clamps, through the mutual cooperation of the displacement mechanism and the lifting mechanism, the panel 11 is driven to gradually approach the positioning ring 20 both in the horizontal and vertical directions, thereby driving the pump body to gradually approach the power source. Under the intervention of the positioning mechanism, the end of the stroke of the displacement mechanism and the lifting mechanism is the optimal position for connecting the pump body and the power source.

[0062] Under the action of the guiding and clamping mechanism, the axis of the rotating shaft of the pump body will be at different positions in the same vertical plane and parallel to the axis of the rotating shaft of the power source. Under the mutual cooperation of the lifting mechanism, the displacement mechanism and the positioning mechanism, the axis of the rotating shaft of the pump body will finally be on the same straight line as the axis of the rotating shaft of the power source, which can ensure the optimal installation position of the pump body and the power source, and avoid the reduction of the working efficiency of the pump body or even damage caused by misalignment installation.

[0063] As a further solution of the present utility model, the displacement mechanism includes a motor 2 fixedly installed on the base 1. A rotating shaft 3 is fixedly connected to the output end of the motor 2. A thread protrusion 301 is fixedly connected to the rotating shaft 3. An internally threaded slider 4 is threadedly connected to the thread protrusion 301.

[0064] The displacement mechanism further includes a guiding rod 7 rotatably installed on the base 1. The guiding rod 7 is connected to the rotating shaft 3 by a belt. A limiting groove 701 is provided on the guiding rod 7. A sliding sleeve 6 is slidably installed on the guiding rod 7. A protrusion 601 fixedly installed on the sliding sleeve 6 is slidably fitted into the limiting groove 701. A connecting block 5 rotatably installed on the sliding sleeve 6 is fixedly connected to the internally threaded slider 4. A connecting rod 8 is fixedly installed on the connecting block 5. A lead screw column 9 is rotatably installed on the connecting rod 8. An internally threaded sleeve 10 fixedly connected to the panel 11 is threadedly connected to the lead screw column 9.

[0065] In this embodiment, when the motor 2 is started, it will drive the rotating shaft 3 to rotate, and drive the internally threaded slider 4 to displace through the threaded connection between the thread protrusion 301 and the internally threaded slider 4. And when the rotating shaft 3 rotates, it will drive the guiding rod 7 to rotate through the belt. When the internally threaded slider 4 moves, it will drive the connecting rod 8 to move synchronously through the connecting block 5, thereby driving the panel 11 to move synchronously through the lead screw column 9. During the movement of the connecting block 5, the sliding sleeve 6 will move synchronously on the guiding rod 7 through the sliding fit between the protrusion 601 and the limiting groove 701, and the rotating guiding rod 7 will drive the sliding sleeve 6 to rotate synchronously through the cooperation between the protrusion 601 and the limiting groove 701. The threaded cooperation between the thread protrusion 301 and the internally threaded slider 4 can drive the pump body to move more labor-savingly in the horizontal direction.

[0066] As a further solution of the utility model, the lifting mechanism includes a follower shaft 16 rotatably installed on the connecting rod 8, and the follower shaft 16 is connected to the sliding sleeve 6 through a bevel gear set; a baffle 12 is fixedly installed on the follower shaft 16, and a driving ring 14 is slidably fitted on the follower shaft 16, and a trigger spring 13 is fixedly installed between the driving ring 14 and the baffle 12; a driven ring 901 capable of meshing with the driving ring 14 is fixedly installed at one end of the lead screw column 9 close to the driving ring 14.

[0067] In this embodiment, when the displacement mechanism acts, the sliding sleeve 6 will rotate synchronously with the guide rod 7; through the bevel gear set, the follower shaft 16 will also rotate synchronously with the guide rod 7, thereby driving the driving ring 14 to rotate synchronously. In the initial position, the tooth blocks on the driving ring 14 and the driven ring 901 will mesh with each other, so the driven ring 901 will also rotate with the rotation of the driving ring 14, thereby driving the lead screw column 9 to rotate. Through the threaded cooperation between the lead screw column 9 and the internal thread sleeve 10, the internal thread sleeve 10 can drive the panel 11 to gradually approach the positioning ring 20 in the vertical direction. Therefore, when the displacement mechanism acts, the connecting rod 8 will drive the follower shaft 16, the driving ring 14, the driven ring 901 and the panel 11 to displace horizontally synchronously, and the lifting mechanism will drive the panel 11 to displace upward.

[0068] As a further solution of the utility model, the positioning mechanism includes a positioning sleeve 17 fixedly installed on the base 1, a positioning column 19 fixedly connected to the positioning frame 21 is slidably fitted in the positioning sleeve 17, and a positioning spring 18 abutted against the positioning column 19 is also fixedly installed in the positioning sleeve 17; a positioning plate 1901 cooperating with the driving ring 14 is fixedly installed on the positioning column 19.

[0069] In this embodiment, first, an external force is used to drive the positioning frame 21 to displace downward to drive the positioning column 19 to slide inward in the positioning sleeve 17, so that the positioning spring 18 is compressed. When the center of the positioning ring 20 is directly below the axis of the power source rotating shaft, the external force is released. Under the elastic force of the positioning spring 18, the positioning column 19 will slide outward in the positioning sleeve 17, thereby driving the positioning ring 20 to displace upward through the positioning frame 21. During this process, the positioning plate 1901 will also displace upward. When the positioning ring 20 abuts against the power source rotating shaft, the positioning plate 1901 stops displacing and remains in place under the elastic force of the positioning spring 18.

[0070] One side of the positioning plate 1901 close to the driving ring 14 is arranged as an inclined surface. When the displacement mechanism drives the driving ring 14 to displace until it contacts the positioning ring 20, the feature of the inclined surface of the positioning plate 1901 will cause the driving ring 14 to displace downward on the follower shaft 16, so that the driving ring 14 disengages from the driven ring 901, thereby causing the lead screw column 9 to stop rotating, that is, the lifting mechanism will not drive the panel 11 to continue to displace upward when the driving ring 14 contacts the positioning plate 1901, and the panel 11 will remain in this position unchanged. At this time, the axes of the rotating shafts of the pump body and the power source on the panel 11 are on the same straight line. If there is still a large gap between the rotating shaft of the pump body and the rotating shaft of the power source at this time, the displacement mechanism will continue to drive the panel 11 to gradually approach the positioning ring 20 in the horizontal direction until the rotating shafts of the pump body and the power source are in close contact.

[0071] As a further solution of the present invention, a support frame 15 is fixedly installed on the base 1, and a plurality of groups of installation openings are provided on the support frame 15.

[0072] In this embodiment, when the positioning ring 20 still cannot contact the rotating shaft of the power source when it is in the maximum displacement state, a larger support frame 15 is replaced to make the rotating shaft of the positioning ring 20 contact.

[0073] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of the present invention, all technical solutions that can implement the present invention in other specific forms are included in the present invention.
