Description

Technical Field

[0001] The present invention relates to the field of auxiliary installation equipment, and in particular to a spindle installation tool. Based on this, the present invention also relates to a spindle installation method using the spindle installation tool. Background Art

[0002] In the industrial fields of mechanical processing and equipment manufacturing, all equipment needs to be installed and connected before the industrial process begins. As a commonly used component, the spindle needs to be accurately installed in place to ensure the smooth operation of the entire industrial process. In the existing spindle installation operations, conventional lifting and manual assisted positioning methods are usually adopted. For example, the spindle is lifted to the vicinity of the installation site by a crane or a simple hanger, and then the installation interface of the spindle and the installed component is gradually approached and docked by mechanical push or the inertia of the crane movement.

[0003] The traditional installation method can complete the installation well when the spindle is installed on a solid device. However, when the spindle installed by the traditional installation method is installed in place, it will generate impact loads on the installed equipment. For high-precision equipment, such as planetary gearboxes with sliding bearings, slight impact loads can also cause damage to the internal structure. Therefore, impact loads are completely prohibited for such equipment. In order to avoid impact loads, a crane is usually used to lift the spindle with multiple slings, and then the crane is slowly moved. The crane is used to move slightly back and forth, and the inertia of the spindle is used to make the spindle stuck in the installation position, and then locked by the locking device. Although the existing installation process can avoid the impact load generated during installation, the entire installation process is extremely time-consuming and requires the use of a crane throughout the process. It is inefficient and also affects the installation of other components.

[0004] Therefore, there is an urgent need for a spindle installation tool that can efficiently install the spindle without generating impact loads on the equipment to which the spindle is installed. Summary of the invention

[0005] The purpose of the present invention is to overcome the following technical problem existing in the prior art: how to provide a mounting device capable of efficiently mounting a main shaft without generating impact load on the device to which it is mounted.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a spindle installation tool, which includes a support module and a locking module. The support module includes a support member and a support seat, the support member includes a bracket placed vertically on the ground and a support plate supported by the bracket, a through hole is provided in the support seat to allow the spindle to pass through drivably so as to limit the spindle, and the top of the support plate is configured to be able to contact with the bottom of the spindle to support the support seat, thereby supporting the spindle. The locking module includes a pull rod, the pull rod is configured to be able to pass through the spindle in the axial direction, and one end of the pull rod is fixedly provided with a baffle that can be blocked by the spindle and stuck at the end of the spindle, and the other end is movably provided with an end cover that can be blocked by a receiving device and stuck outside the receiving device, and on the side of the end cover away from the baffle, a locking nut is threadedly connected to the pull rod to allow the spindle to be pulled toward the end cover by turning the locking nut.

[0007] Preferably, the support member includes at least one lifting member disposed above the bracket, and the support plate is disposed above the lifting member so as to be supported by the lifting member and driven to rise or fall.

[0008] Preferably, the support module further comprises a control panel, and the lifting member is arranged to be controlled by the control panel to be adjusted to different lifting heights.

[0009] Preferably, the lifting member is an electric cylinder.

[0010] Preferably, the supporting module further comprises a ball head rotatably arranged above the lifting member, and the ball head is rotatably connected to the supporting plate to support the supporting plate.

[0011] Preferably, a bearing allowing the main shaft to pass through is fixedly provided in the support seat to limit the main shaft.

[0012] Preferably, the end of the main shaft used to block the baffle is provided with a driving interface connected to the driving device, and the driving interface is provided with a through hole allowing the pull rod to pass through.

[0013] Preferably, the pull rod comprises a plurality of rods detachably connected end to end, so that the length of the pull rod can be adjusted.

[0014] Preferably, one end of the pull rod provided with the baffle is provided with a scale line extending from the end along the axis of the pull rod.

[0015] A second aspect of the present invention provides a spindle installation method, which uses the above-mentioned spindle installation tool, comprising the following steps: S1: Use a lifting device to lift the main shaft and extend it into the accommodating device until the main shaft penetrates into a predetermined position in the mounting through hole of the accommodating device, and then stop the lifting device; S2: Install the locking module so that the pull rod passes through the main shaft, and one end of the pull rod is abutted against the end of the main shaft by the baffle, and the other end of the pull rod is abutted against the receiving device by the end cover, and the locking nut is screwed to drive the main shaft to the installation position by the locking module; S3: Install the support module, measure the coaxiality between the main shaft and the installation through hole, adjust the height of the support seat until the coaxiality reaches the predetermined range, and then remove the lifting equipment.

[0016] Preferably, in step S3, support members with different heights are selected to adjust the coaxiality between the main shaft and the mounting through hole and to support the main shaft.

[0017] The main shaft installation tool provided by the present invention can efficiently install the main shaft without causing impact to the accommodating device through the cooperation of the supporting module and the locking module.

[0018] In the actual installation process, the main shaft is first lifted by the crane, and under the premise of keeping the main shaft stable, the insertion end of the main shaft is quickly moved to a preparatory position close enough to the installation position. The distance between the preparatory position and the installation position can ensure that the crane can move quickly before installation, without worrying about the inertia of the main shaft causing the main shaft to hit the accommodating device, and can also ensure that the pull rod in the locking module can pass through one end of the main shaft and pass through the installation through hole of the insertion end of the main shaft and the accommodating device, so that the main shaft can be pushed to the installation position and locked by the locking module. The pull rod in the locking module can pass through the main shaft and abut against one end of the main shaft with a baffle at one end, and the other end extends out of the installation through hole on the accommodating device. An end cap is first sleeved on the end extending out of the installation through hole, and then a locking nut is sleeved. The locking nut is screwed with the thread set on the pull rod so that it can move in the axial direction of the pull rod by being rotated, so that the end cap can be pushed to move toward the accommodating device by rotating the locking nut. When the end cover is pushed to get stuck on the mounting hole of the accommodating device, continue to rotate the locking nut. At this time, the baffle at the other end of the pull rod is stressed and drives the spindle to move to the installation position until the spindle is installed. Then install the support members in the support module. After ensuring that the support members fully support the support seat, the support seat fully supports the spindle, and the coaxiality of the spindle and the gearbox falls within the predetermined range, the crane can be removed and the locking process of the gearbox locking sleeve is carried out until the installation is completed. In each step of the installation process, especially in the process of the locking nut driving the spindle into the accommodating device, it is necessary to test the coaxiality of the spindle regularly to ensure that the coaxiality of the spindle can fall within the predetermined range. When the crane is withdrawn, the support module should be able to keep the height of the spindle and the angle relative to the mounting hole of the accommodating device consistent with that before the crane is withdrawn, to ensure that the coaxiality of the spindle falls within the predetermined range.

[0019] Through the locking nut, the operator can control the process of the spindle being installed in place, for example, by rotating the locking nut at a slower speed, ensuring that the speed when the spindle contacts the receiving device is slow enough to avoid impact loads. The use of the locking module is fast and does not require careful and slow operation of the crane, thereby improving the efficiency of the spindle installation and allowing the crane to be rotated to other processes that require the crane more quickly after the quick installation, thereby speeding up the efficiency of the entire assembly line.

[0029] In order to achieve the above-mentioned object, the present invention provides a spindle installation tool, such as Figure 1 , Figure 2 and Figure 4 As shown, it includes: The support module 1 includes a support member 11 and a support seat 12. The support member 11 includes a bracket 111 placed perpendicular to the ground and a support plate 114 supported by the bracket 111. The support seat 12 is provided with a through hole allowing the main shaft to rotatably pass through to limit the main shaft 3. The top of the support plate 114 is configured to be able to contact the bottom of the support seat 12 to support the support seat 12, thereby supporting the main shaft 3.

[0030] The locking module 2 includes a pull rod 21, which is configured to penetrate the main shaft 3 axially, and one end of the pull rod 21 is fixedly provided with a baffle 22 that can be blocked by the main shaft 3 and stuck at the end of the main shaft 3, and the other end is movably provided with an end cover 23 that can be blocked by the accommodating device 4 and stuck outside the accommodating device 4. On the side of the end cover 23 facing away from the baffle 22, a locking nut 24 is threadedly connected to the pull rod 21 to allow the main shaft 3 to be pulled toward the end cover 23 by screwing the locking nut 24.

[0031] The main shaft 3 refers to the shaft that rotates and transmits in the mechanical structure, and it plays the main role of rotation processing or transmission in the mechanical structure with multiple shafts. However, those skilled in the art can use the technical solution of the present invention to install other shafts, including but not limited to secondary shafts and other shaft components that have the conditions for using the main shaft installation tooling in addition to the main shaft 3, through simple transformation. The accommodating device 4 can be any device that accommodates the main shaft 3 and is connected to the main shaft 3 for operation, especially a high-precision device that cannot withstand the impact load of the axial direction of the main shaft 3, for example, a planetary gearbox using a sliding bearing. The support plate 114 can be any shape that can contact with the main shaft 3 to stably support the main shaft 3.

[0032] During the actual installation process, the main shaft 3 is first lifted by the crane, and under the premise of keeping the main shaft 3 stable, the insertion end of the main shaft 3 is quickly moved to a preparatory position that is close enough to the installation position. The distance between the preparatory position and the installation position can ensure that the crane can move quickly before installation, without worrying about the inertia of the main shaft 3 causing the main shaft 3 to hit the accommodating device 4, and can also ensure that the pull rod 21 in the locking module 2 can pass through one end of the main shaft 3 and pass through the installation through hole of the insertion end of the main shaft 3 and the accommodating device 4, so that the main shaft 3 can be pushed to the installation position and locked by the locking module 2. The pull rod 21 in the locking module 2 can pass through the main shaft 3 and abut against one end of the main shaft 3 with the baffle 22 at one end, and the other end extends out of the installation through hole on the accommodating device 4. The end cover 23 is first sleeved on the end extending out of the installation through hole, and then the locking nut 24 is sleeved. The locking nut 24 is threadedly connected with the thread set on the pull rod 21 so that it can move in the axial direction of the pull rod 21 by being rotated, so that the end cover 23 can be pushed to move toward the accommodating device 4 by rotating the locking nut 24. When the end cover 23 is pushed to be stuck on the installation through hole of the accommodating device 4, the locking nut 24 is continued to be rotated. At this time, the baffle 22 at the other end of the pull rod 21 is stressed and drives the main shaft 3 to move to the installation position until the main shaft 3 is installed in place. Then install the support member 11 in the support module 1. After ensuring that the support member 11 fully supports the main shaft 3 and the coaxiality of the main shaft and the gear box falls within the predetermined range, the crane can be moved away until the locking nut 24 is fully locked and the installation of the main shaft 3 is completed. At this time, since the spindle 3 is already in the installed position, the locking module 2 can be taken out of the spindle 3 without affecting the spindle 3 and the accommodating device 4, and used for the installation of the next spindle 3. In each step of the installation process, especially in the process of the locking nut driving the spindle into the accommodating device, the coaxiality of the spindle needs to be tested regularly to ensure that the coaxiality of the spindle can fall within the predetermined range. The requirements for coaxiality here should be determined by the staff according to the various parameters of the accommodating device 4 and the spindle 3. When the crane is withdrawn, the support module 1 should be able to keep the height of the spindle 3 and the angle of the installation through hole relative to the accommodating device 4 consistent with that before the crane is withdrawn, so as to ensure that the coaxiality of the spindle 3 falls within the predetermined range. Through the locking nut 24, the operator can control the process of the spindle 3 being installed in place, for example, through a slower rotation speed, to ensure that the speed when the spindle 3 contacts the accommodating device 4 is slow enough so as not to generate impact loads. The locking module 2 is used for fast operation and does not require careful and slow operation of the crane, thereby improving the efficiency of the installation of the spindle 3 and enabling the crane to be rotated more quickly to other process flows requiring the crane after the rapid installation, thereby speeding up the efficiency of the entire assembly line.

[0033] Through the support seat 12, the support module 1 can provide radial constraints on the main shaft 3, thereby ensuring the coaxiality of the main shaft 3 during operation. The support seat can increase the support points on the main shaft 3 through one or more support seats 12, so that the support module 1 can support the main shaft 3 of various lengths, avoiding too few support points in the support module 1, and small support area, which will cause the main shaft 3 to be deformed or even broken by shear force. The operator can take various measures on the through hole in the support seat 12 so that the main shaft 3 can still rotate normally under the limit of the support seat 12.

[0034] The multiple support members 11 can not only distribute the load of the support seat 12 over a larger area to prevent deformation caused by stress concentration, but also adjust the angle and height of the support member relative to the horizontal plane by arranging multiple support members 11 with slightly different heights under a support seat 12, thereby adjusting the coaxiality of the main shaft 3 through the support seat 12 and making it conform to the predetermined range, thereby ensuring the normal operation of the main shaft 3.

[0035] Preferably, if Figure 1 and Figure 3 As shown, the support member 11 includes at least one lifting member 112 disposed above the bracket 111, and the support plate 114 is disposed above the lifting member 112 so as to be supported by the lifting member 112 and driven to rise or fall. When the support module 1 is installed below the spindle 3 to support the spindle 3, the height of the support plate 114 can be adjusted by the lifting member 112 in the support member 11, so that the spindle 3 can be stably supported, thereby ensuring that the coaxiality of the spindle 3 and the accommodating device 4 can be maintained within a predetermined range after the support module 3 is installed. The bracket 111 using the lifting member 112 can adapt to the assembly requirements of various devices and the spindle 3 by adjusting the height of the lifting member 112, so that it can be flexibly applied to a variety of devices. The lifting member 112 can be any component that can drive the support plate 114 to rise and fall, for example, a lifting motor provided with a push rod that can reciprocate in the vertical direction.

[0036] Preferably, the support module 1 further comprises a control panel, and the lifting member 112 is arranged to be controlled by the control panel to be adjusted to different lifting heights, and the staff operates the lifting and lowering of the lifting member 112 through the control panel. Through the control panel, the staff can operate away from the main shaft 3, which saves manpower and ensures safety.

[0037] Preferably, the lifting member 112 can be an electric cylinder. The electric cylinder can be connected to an external control panel and can be finely controlled through program settings, so that when the support module 1 is installed and the crane is removed, it can drive the spindle 3 to rise and fall, and fine-tune the height of the spindle 3 so that the coaxiality of the spindle 3 and the mounting through hole of the accommodating device 4 reaches a predetermined range, and can operate normally. At the same time, the electric cylinder can withstand a large load, so that it can carry a spindle 3 of heavy weight, and adjust the height of the spindle 3 to adjust the coaxiality. It should be noted that in order to adapt to spindles 3 of different sizes and weights, the staff can set a plurality of lifting members 112 supporting the support plate 114 and select a suitable type of lifting member 112, such as a suitable type of electric cylinder, to ensure that the support module 1 can support the spindle 3.

[0038] Preferably, the control panel is pre-loaded with a pre-set program, which can automatically calculate and adjust the lifting range of the lifting member 112 according to the center height of the installation through hole of the accommodating device 4 and the angle between the main shaft 3 and the horizontal plane measured by the staff, and make the coaxiality of the main shaft 3 meet the requirements. By controlling the lifting member 112 through the pre-set program, the accuracy of adjusting the coaxiality of the main shaft 3 is further improved, and errors caused by manual adjustment are prevented.

[0039] Preferably, if Figure 1 and Figure 3 As shown, the support module 1 also includes a ball head 113 rotatably arranged above the lifting member 112, and the ball head 113 is rotatably connected to the support plate 114 to support the support plate 114. When the support member 11 in the support module 1 is installed below the spindle 3, the support plate 114 can be adjusted to the angle with the largest contact area with the spindle 3 when it contacts the spindle 3 through the ball head 113 arranged above the lifting member 112, so as to support the spindle 3 more stably. At the same time, the ball head 113 enables the support plate 114 to be tilted relative to the horizontal plane, and the spindle 3 is supported by the tilted surface, so that the support member 11 can adjust the angle of the spindle 3 relative to the horizontal plane, thereby expanding the adjustment range of the coaxiality of the support member 11 to the spindle 3, and ensuring the coaxiality of the equipment. The ball head 113 has the property of being able to rotate in all directions under load to change the support angle. The ball head 113 is a flexible connector, so it can absorb the slight displacement and vibration during the installation process and operation process, and can better ensure the stable operation of the spindle 3 compared with other connectors.

[0040] By adjusting the lifting member 112 and the ball head 113, the single support member 11 can be moved in the vertical direction, and the support plate 114 can have various angles relative to the horizontal plane to support the support seat 12 from various angles, thereby adjusting the height of the support seat 12 and its angle relative to the horizontal plane to ensure the coaxiality of the main shaft 3.

[0041] Preferably, a bearing that allows the spindle 3 to pass through is fixedly arranged in the support seat 12 to limit the spindle 3. Through the bearing arranged in the support seat 12, the support seat 12 can stably limit the spindle 3 when it rotates to ensure the coaxiality of the spindle 3. The bearing arranged in the support seat 12 can be any bearing that can achieve the limiting effect on the spindle 3, and its specific model and parameters are determined according to various operating parameters of the spindle 3.

[0042] Preferably, if Figure 1 and Figure 2 As shown, the support module 1 includes two support members 11 and a support seat 12. A single support member 11 includes a bracket 111 and two lifting members 112 supported by the bracket 111. The two lifting members 112 are respectively connected to the support plate 114 through a ball head 113 to support the support plate 114. The two support members 11 are respectively arranged at both ends of the support seat 12. The connecting line between the two lifting members 112 in the single support member 11 is parallel to the axis of the main shaft 3. The support module 1 configured in this way can adjust the angle of the support seat 12 on the horizontal plane by adjusting the lifting members 112 respectively, so that a certain corner or a certain side of the support seat 12 is raised or lowered. The height of the support seat 12 can also be adjusted by raising or lowering four lifting members 112 at the same time. Through the above adjustment method, the support seat 12 can be fine-tuned in all directions, so that it can adjust and limit the coaxiality of the main shaft 3 to ensure the normal operation of the main shaft 3.

[0043] Preferably, if Figure 1 and Figure 2 As shown, the end of the spindle 3 used to block the baffle 22 is provided with a drive interface connected to the drive device, and the drive interface is provided with a through hole allowing the pull rod 21 to pass through. The baffle 22 is set to any shape that can be stuck on the end of the spindle 3 without affecting the connection between the drive interface and the drive device. When the spindle 3 is installed, the drive device is connected to the spindle 3 through the drive interface and drives the spindle 3 to move. The baffle 22 that does not affect the connection of the drive device ensures that the spindle installation tool can be used when the spindle 3 is running.

[0044] Preferably, if Figure 2 As shown, the baffle 22 and the end cover 23 can be arranged in a shape symmetrical about the center of the main shaft 3, such as a tic-tac-toe shape or a circle, so that the weight of the main shaft 3 can be evenly distributed around when the main shaft 3 rotates, thereby preventing deflection and wear of the main shaft 3 caused by weight imbalance.

[0045] Preferably, if Figure 4As shown, the tie rod 21 is composed of a plurality of rods that are detachably connected end to end so that the length of the tie rod 21 can be adjusted. The connection method of the rods can be any method with sufficient connection strength, such as threaded connection. Through the tie rod 21 with adjustable length, the main shaft installation tool can be suitable for main shafts 3 of different lengths. By disassembling the tie rod 21 into a plurality of rods, the space required for storing the tie rod 21 is saved. By producing a plurality of rods of the same specification and selecting the number of splicing according to the required length, a large number of tie rods 21 can be produced, and the production cost of the tie rod 21 is reduced through mass production.

[0046] A second aspect of the present invention provides a spindle installation method, which uses the above-mentioned spindle installation tool, comprising the following steps: S1: Use a lifting device to lift the main shaft 3 and extend it into the accommodating device 4 until the main shaft 3 penetrates into a predetermined position in the installation through hole of the accommodating device 4, and then stop the lifting device; S2: Install the locking module 2 so that the pull rod 21 passes through the main shaft 3, and is abutted against the end of the main shaft 3 by the baffle 22 at one end, and abutted against the accommodating device 4 by the end cover 23 at the other end, and the locking nut 24 is screwed so that the locking module 2 drives the main shaft 3 to the installation position; S3: Install the support module 1, measure the coaxiality between the main shaft 3 and the installation through hole, adjust the height of the support seat 12 until the coaxiality reaches a predetermined range, and remove the lifting equipment.

[0047] Preferably, in step S3 , support members 11 with different heights are selected to adjust the coaxiality between the main shaft 3 and the mounting through hole and to support the main shaft 3 .

[0048] Specifically, the spindle installation method comprises the following steps: First, draw a straight line from the end of the spindle 3 away from the insertion end along the axial direction of the spindle 3 to the insertion end. Lift the spindle 3 by the crane, and under the premise of keeping the spindle 3 stable, quickly move the insertion end of the spindle 3 to a preparation position that is close enough to the installation position. The distance between the preparation position and the installation position can ensure that the crane can move quickly before installation without worrying about the spindle 3 hitting the accommodating device 4 due to the inertia, and can also ensure that the pull rod 21 in the locking module 2 can pass through one end of the spindle 3 and pass through the installation through hole of the insertion end of the spindle 3 and the accommodating device 4, so that the spindle 3 can be pushed to the installation position and locked by the locking module 2.

[0049] Then install the locking module 2, wherein the pull rod 21 passes through the spindle 3 and is abutted against one end of the spindle 3 by the baffle 22 at one end, and the other end extends out of the mounting through hole on the accommodating device 4. The end cover 23 is first sleeved on the end extending out of the mounting through hole, and then the locking nut 24 is sleeved. The locking nut 24 is threadedly connected with the thread set on the pull rod 21 so that it can move in the axial direction of the pull rod 21 by being rotated, so that the end cover 23 can be pushed to move toward the accommodating device 4 by rotating the locking nut 24. When the end cover 23 is pushed to be stuck on the mounting through hole of the accommodating device 4, the locking nut 24 is continuously rotated. At this time, the baffle 22 at the other end of the pull rod 21 is stressed and drives the spindle 3 to move to the installed position until the spindle 3 is installed in place. The coaxiality of the installed spindle 3 is tested, and the spindle 3 is adjusted by observing the straight line previously drawn on the spindle 3 to ensure that the axis of the spindle 3 and the mounting through hole of the accommodating device 4 coincide in the horizontal plane.

[0050] Finally, install the support module 1, sleeve the support seat 12 in the support module 1 on the main shaft 3, and use the support member 11 to support the support seat 12. When the support module 1 is fully installed, the crane can be withdrawn. At this time, the main shaft 3 is in the installed position, and the lock 2 can be taken out from the main shaft 3 without affecting the coaxiality of the main shaft 3 and the accommodating device 4, so that the locking module 2 can be used for the installation of the next main shaft 3. The staff measures the angle between the main shaft 3 and the horizontal plane and the height of the center of the mounting through hole in the accommodating device, and inputs them into the control panel. The control panel calculates the lifting amplitude of the lifting member 112 in each support member 11 and drives each lifting member 112 to adjust the coaxiality and height of the main shaft 3 to the parameters required by the main shaft 3.

[0051] Through the locking nut 24 in the locking module 2, the operator can control the process of installing the spindle 3 in place, for example, through a slower rotation speed, to ensure that the speed when the spindle 3 contacts the receiving device 4 is slow enough so as not to generate impact loads. The use of the locking module 2 is fast in operation, and there is no need to carefully operate the crane at a slow speed, which can avoid the impact load generated during installation. Through the lifting member 112 and the control panel in the support module, the coaxiality and height of the spindle 3 can be quickly and accurately adjusted, thereby improving the efficiency of the installation of the spindle 3, and allowing the crane to be rotated more quickly to other process flows that require the crane after the rapid installation is completed, thereby speeding up the efficiency of the entire assembly line. The support module 1 can work together with the locking module 2 and speed up the efficiency of the spindle installation project.
