[0022] For the convenience of understanding the present application, the following will describe the present application in more detail with reference to the drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more intermediate elements therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element, or there can be one or more intermediate elements therebetween. The terms "vertical", "horizontal", "left", "right", "inner", "outer" and similar expressions used in this specification are only for the purpose of illustration.

[0023] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terms used in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0024] In the description of this specification, unless otherwise clearly specified and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific situations.

[0025] In addition, the technical features involved in different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0026] Please refer to Figure 1 , the protector A of the submersible screw pump includes a housing A1, a first joint A2, and a second joint A3. The housing A1 is generally cylindrical. The inner walls at both ends of the housing A1 are respectively provided with a first internal thread (not shown in the figure) and a second internal thread (not shown in the figure). The outer wall of one end of the first joint A2 is provided with a first external thread A21, and the outer wall of one end of the second joint A3 is provided with a second external thread A31. The first external thread A21 is matched with the first internal thread so that the first joint A2 is screwed and fixed to one end of the housing A1, and the second external thread A31 is matched with the second internal thread so that the second joint A3 is screwed and fixed to the other end of the housing A1. Currently, during the assembly process of the protector A, the first joint A2 and the second joint A3 are usually tightened onto the housing A1 by manual screwing. Since the protector A is relatively heavy, and the thread travel required to meet the assembly requirements between the first internal thread and the first external thread A21 and between the second internal thread and the second external thread A31 is relatively large, relying solely on manpower to complete the entire assembly process consumes a large amount of physical strength of the operator and has a high operation difficulty, thereby resulting in low production efficiency.

[0027] Please refer to Figures 2 - 4, To solve the above problems, an embodiment of the present application provides a thread tightening tooling 1000 for tightening a first component and a second component with a thread fit. The thread tightening tooling 1000 includes a base 1, a rotating member 2, a clamping assembly 3, and a driving assembly 4. The base 1 is used for mounting the first component. The rotating member 2 is rotatably mounted on the base 1. The clamping assembly 3 is connected to the rotating member 2, and the clamping assembly 3 is used for mounting the second component. The driving assembly 4 is connected to the rotating member 2, and the driving assembly 4 can drive the rotating member 2 to rotate relative to the base 1. When the first component is mounted on the base 1 and the second component is mounted on the rotating member 2, when the driving assembly 4 drives the rotating member 2 to rotate relative to the base 1, the rotating member 2 drives the clamping assembly 3 mounted with the second component to rotate, so that the second component rotates relative to the first component, and thus the second component with a thread fit and the first component can be tightened.

[0028] When the thread tightening tooling 1000 of the embodiment of the present application is used for the installation of the protector A of the submersible screw pump, at this time, the housing A1 of the protector A can be used as the second component, the first joint A2 of the protector A can be used as the first component, and further, the second joint A3 of the protector A can be used as the second component, and the housing A1 of the protector A can be used as the first component. By the above method, the driving assembly 4 is used to replace manual labor to tighten and fix the first joint A2 and the second joint A3 of the protector A to the housing A1 of the protector A respectively, thereby improving the production efficiency during the assembly of the protector A.

[0029] In some embodiments, the base 1 includes a bottom plate 11 and a first limiting ring 12. The first limiting ring 12 is provided on one side of the bottom plate 11. The bottom plate 11 is provided with a through hole a for the second component to pass through. The first limiting ring 12 is coaxially arranged with the through hole a. The rotating member 2 is rotatably sleeved outside the first limiting ring 12. The first limiting ring 12 is coaxially arranged with the through hole a, so that the rotation axis of the rotating member 2 relative to the first limiting ring 12 coincides with the axis a1 of the through hole a.

[0030] In some embodiments, the inner wall of the first limiting ring 12 is used to limit the outer peripheral wall of the second component, so that the central axis of the thread of the second component coincides with the rotation axis of the rotating member 2 relative to the first limiting ring 12. By making the central axis of the thread of the second component coincide with the rotation axis of the rotating member 2 relative to the first limiting ring 12, the problem of thread jamming caused by the non-concentricity between the thread of the second component and the thread of the first component when the second component rotates driven by the rotating member 2 can be reduced.

[0031] In some embodiments, the inner wall of the through hole a is used to limit the outer peripheral wall of the second component, so that the central axis of the thread of the second component coincides with the rotation axis of the rotating member 2 relative to the first limiting ring 12. When the second component passes through the first limiting ring 12 and enters the through hole a, the inner wall of the through hole a limits the second component. It can be understood that the inner wall of the first limiting ring 12 and the inner wall of the through hole a can separately limit the second component, or cooperate with each other to limit the second component.

[0032] In some embodiments, the base 1 further includes a second limiting ring 13. The second limiting ring 13 is disposed on the other side of the bottom plate 11 facing away from the first limiting ring 12. The second limiting ring 13 is coaxially arranged with the through hole a, and the second limiting ring 13 is for the second component to pass through.

[0033] In some embodiments, the inner wall of the second limiting ring 13 is used to limit the outer peripheral wall of the second component, so that the central axis of the thread of the second component coincides with the rotation axis of the rotating member 2 relative to the first limiting ring 12.

[0034] In some embodiments, the base 1 includes a handle 14. The handle 14 is connected to the bottom plate 11. The handle is for an operator to hold, so as to prevent the base 1 from rotating together with the rotating member 2.

[0035] In some embodiments, the handle 14 is disposed on the side of the bottom plate 11 facing away from the first limiting ring 12.

[0036] In some embodiments, the rotating member 2 includes a driven gear. The driven gear is rotatably sleeved outside the first limiting ring 12. The driving assembly 4 includes a driving gear 41 and a rotation driving member 42. The driving gear 41 meshes with the driven gear, and the rotation driving member 42 is connected to the driving gear 41. The rotation driving member 42 can drive the driving gear 41 to rotate, so as to drive the driven gear to rotate.

[0037] In some embodiments, the rotating member 2 further includes a plurality of rolling elements (not shown in the figure). The outer peripheral wall of the first limiting ring 12 is provided with a first annular groove (not shown in the figure), and the inner peripheral wall of the driven gear is provided with a second annular groove (not shown in the figure). The inner walls of the first annular groove and the second annular groove together enclose an annular channel (not shown in the figure), and a plurality of rolling elements are disposed in the annular channel. Compared with the driven gear rotating relative to the first limiting ring 12 by sliding, the rolling elements roll in the annular channel, greatly reducing the friction force.

[0038] In some embodiments, the rotating member 2 further includes a plurality of cages (not shown in the figure). A cage is disposed between two adjacent rolling elements. The cage evenly spaces the rolling elements apart. The cage can prevent the rolling elements from directly contacting each other, thereby reducing friction and wear, and guiding the rolling elements to ensure their smooth operation in the annular channel.

[0039] In some embodiments, the driving assembly 4 further includes a transmission shaft 43. One end of the transmission shaft 43 is connected to the driving gear 41, and the other end of the transmission shaft 43 is connected to the output shaft of the rotary driving member 42.

[0040] In some embodiments, the transmission shaft passes through the bottom plate 11. The driving gear 41 is disposed on the surface of the bottom plate 11 where the first limiting ring 12 is provided. The central axis of the driving gear 41 is parallel to the central axis of the driven gear. The rotary driving member 42 is located on the side of the bottom plate 11 facing away from the first limiting ring 12.

[0041] Please refer to Figure 3 and Figure 4 , in some embodiments, a coupling groove e is provided at one end of the transmission shaft 43 away from the driving gear 41. The coupling groove e is used to connect with the driving head of an electric torque wrench. When the electric torque wrench serves as the rotary driving member 42, after inserting the driving head of the electric torque wrench into the coupling groove e, starting the electric torque wrench can drive the transmission shaft 43 to rotate.

[0042] It should be understood that the present application does not specifically limit the type and structure of the driving assembly 4. For example, in other embodiments of the present application, the driving assembly 4 can use a belt and a pulley to transmit motion and power, or use a chain and a sprocket to transmit motion and power, etc. The rotary driving member 42 can be an electric motor, a pneumatic motor, a hydraulic motor, etc., which will not be elaborated one by one here.

[0043] In some embodiments, the clamping assembly 3 includes a first clamping jaw 31, a second clamping jaw 32, a first fixing block 33, and a first adjusting rod 34. The first clamping jaw 31 and the second clamping jaw 32 are oppositely arranged, and the first clamping jaw 31 and the second clamping jaw 32 are used to jointly clamp the second component. The first fixing block 33 is fixedly connected to the rotating member 2. One end of the first adjusting rod 34 passes through the first fixing block 33 and is connected to the first clamping jaw 31. The first adjusting rod 34 can drive the first clamping jaw 31 to approach or move away from the second clamping jaw 32. When installing the second component, the first adjusting rod 34 drives the first clamping jaw 31 to move in the direction towards the second clamping jaw 32, thereby clamping and fixing the second component between the first clamping jaw 31 and the second clamping jaw 32. When the second component needs to be removed from the first component after being tightened, the first adjusting rod 34 drives the first clamping jaw 31 to move in the direction away from the second clamping jaw 32, so that the first clamping jaw 31 and the second clamping jaw 32 loosen the second component.

[0044] In some embodiments, the first fixing block 33 is provided with a first threaded hole (not shown in the figure), and the first adjusting rod 34 is provided with a third external thread (not shown in the figure). Along the direction from the first fixing block 33 towards the second clamping jaw 32, the first adjusting rod 34 is screwed into the first threaded hole through the third external thread. By turning the first adjusting rod 34, the rotational motion of the third external thread is converted into the linear motion of the first adjusting rod 34, and thus the first clamping jaw 31 can be driven to approach or move away from the second clamping jaw 32.

[0045] It can be understood that the first adjusting rod 34 is not limited to driving the movement of the first clamping jaw 31 in the above-mentioned way of thread engagement. In some other embodiments, the first adjusting rod 34 can also use devices such as motors and cylinders as power sources to drive the movement of the first clamping jaw 31.

[0046] In some embodiments, the clamping assembly 3 further includes a second fixing block, and the second fixing block is fixedly connected to the rotating member 2, and the second clamping jaw 32 is fixedly connected to the second fixing block.

[0047] In some embodiments, the clamping assembly 3 further includes a second fixing block (not shown in the figure) and a second adjusting rod (not shown in the figure). The second fixing block is fixedly connected to the rotating member 2, one end of the second adjusting rod passes through the second fixing block and is connected to the second clamping jaw 32, and the second adjusting rod can drive the second clamping jaw 32 to approach or move away from the first clamping jaw 31. The first adjusting rod 34 drives the first clamping jaw 31 to approach the second clamping jaw 32, and the second adjusting rod drives the second clamping jaw 32 to approach the first clamping jaw 31. The first clamping jaw 31 and the second clamping jaw 32 can move towards each other to jointly clamp and fix the second component.

[0048] In some embodiments, the second fixing block is provided with a second threaded hole (not shown in the figure), and the second adjusting rod is provided with a fourth external thread (not shown in the figure). Along the direction from the second fixing block towards the first clamping jaw 31, the second adjusting rod is screwed into the second threaded hole through the fourth external thread. By turning the second adjusting rod, the rotational motion of the fourth external thread is converted into the linear motion of the second adjusting rod, and thus the second clamping jaw 32 can be driven to approach or move away from the first clamping jaw 31.

[0049] It can be understood that the second adjusting rod is not limited to driving the movement of the second clamping jaw 32 in the above-mentioned way of screwing in or out. In some other embodiments, the second adjusting rod can also use devices such as motors and cylinders as power sources to drive the movement of the second clamping jaw 32.

[0050] It can also be understood that the clamping assembly 3 is not limited to the above-described structure including the first jaw 31, the second jaw 32, the first fixing block 33, and the first adjusting rod 34. In some other embodiments, the clamping assembly 3 can also be any other form of fixture, as long as it can clamp and fix the first component to the first limiting ring 12. For example, the clamping assembly 3 can also be a fixture that provides a pre-tightening force through a spring.

[0051] In some embodiments, the thread tightening tooling 1000 further includes a fixed bracket 6, and the fixed bracket 6 is used to support the base 1 and fix the first component.

[0052] In some embodiments, the fixed bracket 6 includes a fixed seat 61 and a locking member 62, and the locking member 62 is used to lock the first component to the fixed seat 61.

[0053] Please refer to Figure 1 、 Figure 4 and Figure 5 , in some embodiments, the locking member 62 is a fixing bolt. The fixed seat 61 is provided with a receiving hole (not shown in the figure), and at least two third threaded holes (not shown in the figure) are provided around the receiving hole. The number of the locking members 62 is the same as the number of the third threaded holes. An outer peripheral wall of an end of the first joint A2 of the protector A away from the housing A1 is provided with an annular mounting seat A22, and the annular mounting seat A22 is provided with bolt holes (not shown in the figure) corresponding to the third threaded holes one by one. Insert the end of the first joint A2 away from the housing A1 into the receiving hole, make the annular mounting seat A22 abut against the fixed seat 61 along the direction in which the first joint A2 is inserted into the receiving hole, align the third threaded holes with the bolt holes one by one, and a locking member 62 passes through a third threaded hole and is screwed and fixed to a threaded hole, so as to fix the first joint A2 to the fixed seat 61.

[0054] It can be understood that the specific structure of the fixed seat 61 can be correspondingly set according to the structure of the actual first component, as long as the first component can be kept fixed and does not rotate together with the second component when the second component is rotated by the thread tightening tooling 1000. For example, in the aforementioned application to the protector A, since one end of the first joint A2 of the protector A is provided with an annular mounting seat A22 having bolt holes, the fixed seat 61 can be configured to have third threaded holes corresponding to the bolt holes, and the first joint A2 is fixed by the locking member 62. When the second component itself does not have a fixed structure that can be utilized, the second component can also be fixed by setting a fixture on the fixed seat 61 in a clamping and fixing manner. When the second component is not a cylindrical tube, for example, when the second component is in a cuboid shape, the second component can also be fixed by setting a limiting groove on the fixed seat 61 that matches the shape of the second component and inserting the second component into the limiting groove.

[0055] In some embodiments, the fixing bracket 6 includes a fixing base 61, a column 63, a cantilever 64, and a balancer 65. The two ends of the column 63 are respectively connected to the fixing base 61 and the cantilever 64. One end of the balancer 65 facing away from the fixing base 61 is connected to the cantilever 64, and the other end of the balancer 65 is connected to the base 1. By providing the balancer 65 to suspend the base 1 on the column 63, the effort can be saved to facilitate the adjustment of the height of the base 1 during the operation. The balancer 65 can be selected as a spring balancer, a pneumatic balancer, an electric balancer, etc. according to the actual situation. The fixing base 61 is also used to fix the first component, and the way of fixing the first component by the fixing base 61 can refer to the above embodiments, which will not be elaborated here one by one.

[0056] In some embodiments, the number of balancers 65 is two, and the opposite ends of the base 1 are respectively suspended on the cantilever 64 through the two balancers 65.

[0057] Please refer to Figures 2 - 4 , in some embodiments, first connection holes c and second connection holes d are respectively provided at the opposite ends of the bottom plate 11. The first connection hole c is used for the suspension cable 651 of a balancer 65 to be connected to the base 1, and the second connection hole d is used for the suspension cable 652 of the other balancer 65 to be connected to the base 1.

[0058] For the convenience of the reader to understand the present utility model, the working process of applying the thread tightening tooling 1000 in this embodiment to a protector A of a submersible screw pump will be fully described below:

[0059] The operation process of screwing and fixing the housing A1 of the protector A as the second component to the first joint A2 as the first component:

[0060] First, fix and install the first joint A2 of the protector A on the fixing base 61 through the locking member 62;

[0061] Then screw the first internal thread of the housing A1 onto the first external thread A21 of the first joint A2 so that a certain stroke is engaged between the first internal thread and the first external thread A21;

[0062] Next, sleuth the first limiting ring 12 and the base 1 suspended by the balancer 65 on the outer peripheral wall of the housing A1. The first limiting ring 12 and the inner wall of the through hole a play a limiting role on the housing A1, so that the central axis z2 of the housing A1 coincides with the central axis b1 of the first limiting ring 12. Furthermore, the central axis of the first internal thread of the housing A1 coincides with the rotation axis of the driven gear rotating relative to the first limiting ring 12. Adjust the first adjusting rod 34 so that the first clamping jaw 31 and the second clamping jaw 32 jointly clamp the housing A1 tightly;

[0063] Finally, hold the handle 13 and start the rotary drive 42 to cause the driving gear 41 to drive the driven gear to rotate, thereby driving the housing A1 to rotate relative to the first joint A2. The engagement stroke between the first internal thread of the housing A1 and the first external thread A21 of the first joint A2 increases until the housing A1 is screwed and fixed to the first joint A2. Thus, the threaded connection between the housing A1 as the second component and the first joint A2 as the first component is completed.

[0064] After the housing A1 of the protector A is screwed and fixed to the first joint A2, the operation process of further screwing and fixing the second joint A3 of the protector A as the second component to the housing A1 as the first component. At this time, the housing A1 is indirectly fixed to the fixed seat 61 through the first joint A2:

[0065] First, manually screw the second external thread A31 of the second joint A3 onto the internal thread of the housing A1 so that a certain engagement stroke is formed between the second external thread A31 and the internal thread of the housing A1;

[0066] Then, adjust the height of the base 1 so that the first limit ring 12 and the through hole a move to be sleeved on the outer peripheral wall of the second joint A3. The inner walls of the first limit ring 12 and the through hole a limit the second joint A3, making the central axis z3 of the second joint A3 coincide with the central axis of the first limit ring 12. Furthermore, the central axis of the second external thread A31 coincides with the rotation axis of the driven gear relative to the first limit ring 12. Adjust the first adjusting rod 34 so that the first jaw 31 and the second jaw 32 jointly clamp the second joint A3. Among them, since the base 1 is suspended on the cantilever 64 by the balancer 65, the balancer 65 can make the base 1 in a weightless state, and the locking function of the balancer 65 can keep the base 1 at a preset height, thus greatly reducing the labor intensity of the operator;

[0067] Finally, hold the handle 13 and start the rotary drive 42 to cause the driving gear 41 to drive the driven gear to rotate, thereby driving the second joint A3 to rotate relative to the housing A1. The engagement stroke between the second internal thread of the second joint A3 and the second external thread A31 increases until the second joint A3 is screwed and fixed to the housing A1. Thus, the threaded connection between the second joint A3 as the second component and the housing A1 as the first component is completed.

[0068] The above are only the embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present application.
