Description

Technical Field

[0001] The invention relates to the technical field of component assembly, and in particular to a seal installation tool and method for a bearing cover frame of a straightening machine. Background Art

[0002] The support roller assembly is the core component of the straightening machine. Its assembly accuracy and working state directly affect the operating state of the working roller and the overall accuracy of the straightening machine. A straightening machine has a large number of support rollers. The installation of the bearing cover frame seal directly affects the lubrication effect of the support roller bearing in the later stage. If the frame seal is damaged and cannot guarantee the pressure, the damaged frame seal needs to be removed and a new frame seal needs to be installed. In order to ensure the sealing effect, the frame seal and the bearing cover groove are generally transition fit or interference fit, so the installation is difficult.

[0003] When installing the skeleton seal of the bearing cover of the straightening machine in the prior art, a 1 / 6 arc piece is found and the skeleton seal is pressed into the bearing cover by hammering back and forth. This method has low working efficiency, and the skeleton of the skeleton seal is very susceptible to uneven hammering force, which affects the sealing effect and may even cause it to be scrapped and unusable. Summary of the invention

[0004] In order to solve the technical problems existing in the above-mentioned prior art, the present invention provides a seal installation tool and method for the bearing cover frame of a straightening machine. The specific technical solution is as follows:

[0005] In the first aspect, a tool for installing a skeleton seal of a bearing cover of a straightening machine is provided, the tool comprising: a base, a support frame, a positioning guide sleeve, a pressure cover and a pressing mechanism; the positioning guide sleeve is used to be mounted on the stop of the bearing cover to position the skeleton seal; the support frame is arranged on the base, the pressing mechanism is arranged on the support frame, the pressing mechanism is connected to the pressure cover, and is used to drive the pressure cover to move along the mid-vertical direction of the pressure cover; the bottom surface of the pressure cover is provided with a protrusion that is compatible with the groove on the skeleton oil seal, and there is a storage space between the bottom surface of the pressure cover and the bottom surface of the base for accommodating the bearing cover.

[0006] In a possible design, the base is provided with a plurality of adjustment mechanisms evenly distributed along the circumferential direction for adjusting the position of the bearing cover.

[0007] In a possible design, the adjustment mechanism includes: a base plate and a top screw; the base plate is vertically connected to the base, and a threaded hole matching the top screw is provided on the base plate, and the top screw passes through the threaded hole and one end is opposite to the bearing cover.

[0008] In a possible design, the adjustment mechanism further includes a locking nut sleeved on the top screw, for locking the top screw after the top screw moves to a preset position.

[0009] In a possible design, the pressing mechanism includes: a first connecting rod, a second connecting rod, a handle, a pressure rod and a limiting sleeve; one end of the first connecting rod is hinged to the support frame, and the other end is hinged to one end of the handle; one end of the second connecting rod is hinged to the handle, and the other end is hinged to the top end of the pressure rod; the limiting sleeve is arranged on the support frame, and the limiting sleeve is aligned with the pressure cover; the pressure rod passes through the limiting sleeve, and the bottom end is connected to the pressure cover.

[0010] In a possible design, an observation hole is provided on the gland.

[0011] In a second aspect, a method for installing a seal of a straightening machine bearing cover frame is provided, the method comprising:

[0012] Put the positioning guide sleeve on the stop of the bearing cover;

[0017] In a possible design, after the bearing cover is pushed into the receiving space between the base and the pressure cover, the top screw is turned to adjust the position of the bearing cover so that the bearing cover and the pressure cover are aligned.

[0018] In one possible design, after the bearing cover is pushed into the storage space between the base and the pressure cover, the position of the bearing cover is visually adjusted to allow the bearing cover and the pressure cover to be initially aligned. The pressing mechanism is then actuated to press the pressure cover into the groove of the skeleton seal. The position of the bearing cover is then fine-tuned by rotating the top screw to allow the bearing cover and the pressure cover to be completely aligned. The pressing mechanism then drives the pressure cover to continue pressing down to press the skeleton seal into the bearing cover.

[0019] In one possible design, after turning the top screw to adjust the position of the bearing cover so that the bearing cover and the pressure cover are centered, turn the locking nut until it is close to the base plate.

[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] The technical solution provided by the embodiments of the present invention is described in detail below with reference to the accompanying drawings.

[0030] In a first aspect, an embodiment of the present invention provides a seal installation tool for a bearing cover frame of a straightening machine, as shown in the attached Figure 1-3As shown, the tooling includes: a base 1, a support frame 2, a positioning guide sleeve 3, a pressure cover 4 and a pressing mechanism 5; the positioning guide sleeve 3 is used to be sleeved on the stop of the bearing cover X to position the skeleton seal Y; the support frame 2 is arranged on the base 1, and the pressing mechanism 5 is arranged on the support frame 2. The pressing mechanism 5 is connected to the pressure cover 4 and is used to drive the pressure cover 4 to move along the mid-vertical line direction of the pressure cover 4; the bottom surface of the pressure cover 4 is provided with a protrusion that is compatible with the groove on the skeleton oil seal, and there is a storage space for accommodating the bearing cover X between the bottom surface of the pressure cover 4 and the bottom surface of the base 1.

[0031] The following is a description of the method for using the seal installation tool for the bearing cover frame of the straightening machine provided in the embodiment of the present invention:

[0032] First, put the positioning guide sleeve 3 on the stopper of the bearing cover X to ensure that the end faces fit. Place the skeleton seal Y on the bearing cover X and in the positioning guide sleeve 3. The positioning guide sleeve 3 serves as a positioning guide for the skeleton seal Y. Simply place the skeleton seal Y in the positioning guide sleeve 3 to determine the relative position of the skeleton seal Y and the bearing cover X and install them in place. At this point, the assembly of the positioning guide sleeve 3, the skeleton seal Y and the bearing cover X is completed. Then push the bearing cover X into the storage space between the base 1 and the pressure cover 4, and align the bearing cover X with the pressure cover 4 (that is, the central axis of the bearing cover X is in line with the central axis of the pressure cover 4, and the meaning of centering is the same below). The pressing mechanism 5 moves to press the pressure cover 4 into the groove of the skeleton seal Y. The pressing mechanism 5 drives the pressure cover 4 to continue pressing down to press the skeleton seal Y into the bearing cover X.

[0033] It can be seen that the installation tool for the skeleton seal of the bearing cover of the straightening machine provided by the embodiment of the present invention assists in positioning the skeleton seal Y through the positioning guide sleeve 3, ensuring that the skeleton seal Y is in the proper position on the bearing cover X before installation, and avoiding installation damage caused by misalignment. The pressing mechanism 5 drives the pressure cover 4 to move and evenly applies force to the entire surface of the skeleton seal Y, so that the skeleton seal Y is pressed into the bearing cover X, and the force is evenly applied to avoid deformation. The installation of the skeleton seal Y is completed by a single action of the pressing mechanism 5, which is simple and fast, with high installation efficiency, and saves labor consumption.

[0034] Furthermore, in the installation tool provided in the embodiment of the present invention, a plurality of adjustment mechanisms 6 evenly distributed along the circumferential direction are provided on the base 1 for adjusting the position of the bearing cap X. By providing the adjustment mechanism 6 to adjust the position of the bearing cap X, the bearing cap X and the pressure cap 4 can be accurately aligned.

[0035] As for the structure of the adjustment mechanism 6, an example is given below:

[0036] As attached Figure 1As shown, the adjustment mechanism 6 includes: a base plate 61 and a top screw 62; the base plate 61 is vertically connected to the base 1, and a threaded hole adapted to the top screw 62 is provided on the base plate 61, and the top screw 62 passes through the threaded hole and one end thereof is opposite to the bearing cover X. In this arrangement, through the threaded connection between the top screw 62 and the base, the length of the top screw 62 extending into the receiving space varies when the top screw 62 rotates, and one end of the top screw 62 abuts against the bearing cover X to adjust the position of the bearing cover X.

[0037] Furthermore, the adjustment mechanism 6 may also include a locking nut 63 mounted on the top screw 62, which is used to lock the top screw 62 after the top screw 62 moves to a preset position. With such a configuration, when the top screw 62 is rotated to adjust the position, the locking nut 63 needs to be rotated outward first to keep a certain distance between the locking nut 63 and the base, and reserve a travel for the top screw 62 to move. After the top screw 62 is rotated to adjust the bearing cover X to a preset position, the locking nut 63 is rotated to be close to the base, and the top screw 62 cannot be further screwed inward. By setting the locking nut 63 to lock the position of the top screw 62, when installing the skeleton seal Y of the bearing cover X of the same specification, there is no need to repeatedly adjust the position of the top screw 62. It is only necessary to contact the end of the bearing cover X with the top screw 62 to determine that the bearing cover X and the pressure cover 4 are aligned and subsequent pressing operations can be performed.

[0038] In the embodiment of the present invention, the pressing mechanism 5 is used to drive the pressure cover 4 to move downward. The pressing mechanism 5 needs to be able to provide a large pressure and the force application process is relatively gentle. Based on the above requirements, an example of a pressing mechanism 5 that meets the use requirements is given below:

[0039] As attached Figure 1-3 As shown, the pressing mechanism 5 includes: a first connecting rod, a second connecting rod, a handle 51, a pressing rod 52 and a limiting sleeve 53; one end of the first connecting rod is hinged on the support frame 2, and the other end is hinged to one end of the handle 51, one end of the second connecting rod is hinged to the handle 51, and the other end is hinged to the top end of the pressing rod 52; the limiting sleeve 53 is arranged on the support frame 2, and the limiting sleeve 53 is aligned with the pressing cover 4; the pressing rod 52 passes through the limiting sleeve 53, and the bottom end is connected to the pressing cover 4.

[0040] The limit sleeve 53 is used to limit the pressing rod 52 to ensure the vertical movement of the pressing rod 52. By setting the handle 51, a lever mechanism is formed, and the worker can complete the pressing operation with less force, reducing the difficulty of the operation. Furthermore, the pressing mechanism 5 is constructed as a crank slider mechanism (four-bar linkage mechanism) as described above. By calculating and determining the movement trajectory of the handle 51, it can be ensured that the force state during the pressing process is better, and the stroke and the like can meet the assembly requirements.

[0041] Optionally, the gland 4 and the bottom end of the pressure rod 52 are detachably connected to facilitate replacement of the specifications of the gland 4. By adjusting the specifications of the positioning guide sleeve 3, it can adapt to the installation of skeleton seals Y of different specifications, with a wide range of applications and strong versatility.

[0042] Optionally, in order to facilitate observation of the assembly process, an observation hole 7 is provided on the gland 4. With this arrangement, the staff can determine the installation state below the gland 4 through the observation hole 7, so as to be able to learn about the fault in time and stop work for maintenance.

[0043] In a second aspect, an embodiment of the present invention provides a method for installing a seal of a straightening machine bearing cover frame, the method comprising:

[0044] Put the positioning guide sleeve 3 on the stopper of the bearing cover X;

[0045] Place the skeleton seal Y on the bearing cover X and in the positioning guide sleeve 3;

[0046] Push the bearing cover X into the storage space between the base 1 and the pressure cover 4, and align the bearing cover X with the pressure cover 4;

[0047] The pressing mechanism 5 is actuated to press the gland 4 into the groove of the skeleton seal Y;

[0048] The pressing mechanism 5 drives the pressure cover 4 to continue pressing down to press the skeleton seal Y into the bearing cover X.

[0049] The method for installing the skeleton seal of the bearing cover of the straightening machine provided by the embodiment of the present invention assists in positioning the skeleton seal Y through the positioning guide sleeve 3, ensuring that the skeleton seal Y is in the proper position on the bearing cover X before installation, and avoiding installation damage caused by misalignment. The pressing mechanism 5 drives the pressing cover 4 to move and uniformly applies force to the entire surface of the skeleton seal Y, so that the skeleton seal Y is pressed into the bearing cover X, and the force is uniformly applied to avoid deformation. The installation of the skeleton seal Y is completed by a single action of the pressing mechanism 5, which is simple and fast, with high installation efficiency, and saves labor consumption.

[0050] After the bearing cover X is pushed into the receiving space between the base 1 and the gland 4, the top screw 62 is rotated to adjust the position of the bearing cover X so that the bearing cover X is aligned with the gland 4. With this arrangement, the installation process of the skeleton seal Y can be completed with a subsequent pressing operation.

[0051] Alternatively, after the bearing cover X is pushed into the storage space between the base 1 and the gland 4, the position of the bearing cover X is visually adjusted so that the bearing cover X and the gland 4 are initially aligned, and then the pressing mechanism 5 is operated to press the gland 4 into the groove of the skeleton seal Y, and then the top screw 62 is rotated to fine-tune the position of the bearing cover X so that the bearing cover X and the gland 4 are completely aligned, and then the pressing mechanism 5 drives the gland 4 to continue to press down to press the skeleton seal Y into the bearing cover X. Due to the fact that the connection accuracy and force between the gland 4 and the skeleton seal Y are both small, the bearing cover X is moved by the lateral force generated when the gland 4 and the skeleton seal Y are matched to correct the position of the bearing cover X. The top screw 62 is only responsible for subsequent fine-tuning, and the adjustment range of the top screw 62 can be narrowed, and then a top screw 62 with higher accuracy can be set to further improve the centering effect.

[0052] Regardless of which centering method is used, after rotating the top screw 62 to adjust the position of the bearing cover X so that the bearing cover X and the gland 4 are aligned, the locking nut 63 is rotated to be close to the base plate 61. When the skeleton seal Y of the bearing cover X with the same specification is subsequently installed, the bearing cover X and the gland 4 can be aligned by ensuring that the bearing cover X is in contact with the top screw 62. In this way, the efficiency of the subsequent installation of the skeleton seal Y of the bearing cover X with the same specification is significantly improved.

[0053] In summary, the straightening machine bearing cover skeleton seal installation tooling and method provided in the embodiments of the present invention fill the gap in skeleton seal Y assembly tooling, and have a universal cavity. By adjusting the specifications of the positioning guide sleeve 3 and the pressure cover 4, it can adapt to the installation of all commonly used skeleton seals Y; the clamping force is uniform, avoiding the risk of deformation of the skeleton seal Y; the operation is simple, the practicability is strong, the efficiency is high, the cost is low, and the precision is high.
