Description

Technical Field

[0001] This utility model relates to the field of twin-screw pump assembly technology, and in particular to a twin-screw pump housing disassembly and assembly device. Background Technology

[0002] In the manufacturing process of twin-screw pumps, especially during the installation of the housing, the middle housing has left-handed and right-handed external threads on both sides, with the left-handed housing having left-handed internal threads and the right-handed housing having right-handed internal threads. During assembly, the middle housing must be rotated while the two side housings remain stationary, and the side housings must be engaged and moved towards the middle housing to achieve a locking mechanism. However, existing installation tools cannot meet these requirements, resulting in low installation accuracy of the twin-screw pump housing, friction between the internal screws and the housing, and affecting the overall lifespan of the twin-screw pump. Therefore, proposing a twin-screw pump housing disassembly and assembly device is of great significance. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, this utility model provides a device for disassembling and assembling a twin-screw pump housing.

[0004] This utility model is achieved by adopting the following technical solution.

[0005] A twin-screw pump housing disassembly and assembly device includes a guide mechanism, clamping mechanisms on both sides above the guide mechanism, and a rotating mechanism between the two clamping mechanisms. The guide mechanism includes a guide rail with two sliders connected to the sliders. The clamping mechanism includes an outer ring and an inner ring, with a plurality of set screws penetrating the inner ring around its circumference. The rotating mechanism includes an outer ring with a plurality of push rods penetrating it around its circumference. The edge of the outer ring meshes with a bevel gear shaft, which is connected to a motor via a coupling.

[0006] Furthermore, a support groove is formed on the support block to match the shape of the left-handed or right-handed shell.

[0007] Furthermore, the two sides of the outer ring of the clamping mechanism are fixed to the ground by anchor bolts and nuts.

[0008] Furthermore, the inner wall of the outer ring of the clamping mechanism is provided with a number of guide grooves, and the outer wall of the inner ring of the clamping mechanism is provided with a number of guide keys, and the guide grooves and guide keys are matched.

[0009] Furthermore, the outer ring of the rotating mechanism is also provided with a hydraulic channel and a hydraulic hole, and the push rod is placed in the hydraulic channel, so that the centripetal or centrifugal motion of the push rod is controlled by hydraulic pressure.

[0010] This application has the following beneficial effects.

[0011] This utility model device can lock the housing by rotating the middle housing, so that the left-hand and right-hand housings can be engaged simultaneously without rotation, and move axially toward the middle housing. This ensures axial installation accuracy while improving the efficiency of on-site housing assembly. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1-4 As shown, a twin-screw pump housing disassembly and assembly device includes a rotating mechanism 1, a clamping mechanism, and a guiding mechanism. The guiding mechanism is installed on the ground, and two clamping mechanisms are provided, which are installed on the ground by anchor bolts and distributed on both sides above the guiding mechanism. The rotating mechanism is located in the middle of the two clamping mechanisms.

[0019] The guiding mechanism includes a guide rail 7, a first slider 8, a second slider 9, a first support block 10, and a second support block 11. The guide rail 7 is connected to the ground by bolts. The first slider 8 and the second slider 9 are inserted into the guide rail 7 through guide grooves on the guide rail 7. Under the guidance of the guide grooves, the first slider 8 and the second slider 9 can move linearly along the guide rail 7. The first support block 10 and the second support block 11 are connected to the first slider 8 and the second slider 9 by bolts respectively. They can move linearly along the guide rail 7 with the sliders. The support blocks are provided with support grooves that match the shape of the left and right rotating shells to support the left and right rotating shells and prevent deflection deformation caused by gravity.

[0020] The clamping mechanism includes an outer ring 16, an inner ring 17, set screws 18, anchor bolts 12, and nuts 13. The outer ring 16 has six guide grooves evenly distributed inside. Two fixing holes are provided on the outer side of the outer ring 16. The anchor bolts 12 pass through the fixing holes, and two nuts 13 are provided on both sides of the fixing holes. The anchor bolts 12 can fix the outer ring 16 to the ground, and the two nuts 13 can adjust the height of the outer ring 16. The outer side of the inner ring 17 has six guide keys (not shown). These six guide keys can engage with the six guide grooves on the inner side of the outer ring 16 and slide within the guide grooves. The inner ring 17 has six threaded holes evenly distributed circumferentially. Six set screws 18 are connected to the inner ring 17 through these threaded holes. When a housing is inserted into the inner ring 17, it can be fixed by the set screws 18, and rotation is prevented by the guide keys.

[0021] Taking the left-handed housing 4 as an example, place the left-handed housing 4 into the inner ring 17 of the clamping mechanism and lock it with the six circumferential set screws 18. Then insert the inner ring 17 of the clamping mechanism along the track of the outer ring 16 of the clamping mechanism, ensuring that the inner ring 17 of the clamping mechanism can only move linearly relative to the outer ring 16 of the clamping mechanism and cannot rotate. In the same way, install the right-handed housing 6 into the clamping mechanism 3.

[0022] The rotating mechanism includes an outer ring 21, push rods 20, a motor, and a bevel gear shaft 19. The outer ring 21 has a hydraulic channel, a first hydraulic hole 14, and a second hydraulic hole 15. Six push rods 20 are evenly distributed circumferentially around the outer ring 21. The push rods 20 are placed within the hydraulic channel. Using a hydraulic system, hydraulic oil enters through the first hydraulic hole 14 and exits through the second hydraulic hole 15, allowing control of the push rods 20 to move centrifugally or centrifugally, thereby tightening or loosening the intermediate housing 5 located in the middle of the rotating mechanism 1. The edge of the outer ring 21 meshes with the bevel gear shaft 19, which is connected to the motor via a coupling. The rotating mechanism 1 of the clamping intermediate housing 5 is placed between the clamping mechanism 1 2 and the clamping mechanism 2 3. The bevel gear shaft 19 is driven by a motor to rotate, thereby rotating the rotating mechanism 1, which in turn rotates the intermediate housing 5. While the intermediate housing 5 is rotating, the left-hand housing 4 and the right-hand housing 6 on both sides move axially toward the intermediate housing 5 and are gradually tightened, thereby achieving the effect of the left-hand housing 4 and the right-hand housing 6 engaging synchronously, moving but not rotating.

[0023] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
