Description

Technical Field

[0001] The invention discloses a speed reducer shaft head repair auxiliary device, and relates to the technical field of transmission shaft repair. Background Art

[0002] The existing steps for repairing the shaft head are: first remove other components on the shaft to expose the worn repair part of the reducer shaft head, and wipe off the oil; measure the worn surface and confirm the amount of wear; use oxygen acetylene to perform surface oil baking treatment; use a lathe to perform rough turning until the surface is rough; manually use a brush dipped in alcohol to brush the repair part of the shaft head to clean the surface; mix the Sore carbon nanopolymer material in proportion and apply the material; after the material is cured, turn it to the required size; reinstall the parts and the repair is completed.

[0003] 1. The stability and uniformity of the manual oiling treatment are poor: when using oxygen acetylene oiling treatment, the oiling treatment is generally carried out by manually holding a baking gun. In this process, the manual holding method lacks support and auxiliary devices, and it is impossible to ensure that the flame of the baking gun and the shaft head repair part are always at a constant distance. If the flame is too close to the shaft head repair part, the temperature is too high, which will cause thermal stress changes in the shaft head, and easily cause unnecessary local heat-affected zones in the shaft head part, thereby affecting the rigidity of the shaft head. At the same time, in the prior art, the manual hand-held baking gun oiling method cannot ensure that the flame of the baking gun is in uniform contact with the shaft head repair part, and it is completely dependent on human operation, which is easy to cause irreversible damage to the repaired transmission shaft head; 2. The manual cleaning of the outer wall of the shaft head is not portable and has poor cleaning effect: pouring anhydrous ethanol manually and wiping with cotton cloth cannot fully ensure that the anhydrous ethanol contacts the stains on the outer wall of the shaft head, which can easily lead to residual stains on the outer wall of the shaft head, affecting subsequent repair work; 3. The thickness and uniformity of the coating cannot be reasonably controlled during the manual application of the repair material: In the prior art, the repair material is generally placed manually on the repair part of the shaft head, and then the repair material is applied to the repair part using an extrusion cabin. In this process, the thickness of the repair material coating cannot be easily and effectively controlled by humans, and is always greater than the thickness of the wear amount of the shaft head. If this requirement is not met, the uneven application of the repair material will lead to poor quality of the shaft head repair.

[0004] Therefore, the present invention proposes a reducer shaft head repair auxiliary device to make up for and improve the deficiencies of the prior art. Summary of the invention

[0016] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: The reducer shaft head repair auxiliary device, through the slotted ring and the annular groove 1, when the staff holds the example baking gun to carry out oiling treatment on the shaft head, the flame-spraying end of the example baking gun is indirectly fixed to the stabilizing slide plate and the stabilizing ring through the stabilizing plate, thereby ensuring the stability and safety of the shaft head oiling link of the example baking gun, and at the same time, the example baking gun can not only make a circular motion along the annular groove 1 with the help of the stabilizing slide plate to evenly carry out oiling treatment on the shaft head repair part, but also the example baking gun can also move in the horizontal direction with the T-shaped groove 1 as the motion trajectory, so as to further ensure the uniformity of the shaft head oiling by the staff holding the example baking gun. Compared with the method of simply manually holding the example baking gun to oil in the prior art, the shaft head repair device can provide the staff with a relatively more stable and convenient operating space, thereby ensuring the effectiveness and uniformity of the staff holding the example baking gun to oil the shaft head; The staff takes the position of the shaft head to be repaired as a reference and adjusts the distance between the bottom of the flame spray end of the example baking gun and the shaft head to be repaired to ensure that the two are within a suitable baking oil distance, thereby ensuring that the vertical distance between the flame and the shaft head to be repaired is relatively constant during the baking oil process of the example baking gun, avoiding the situation in which the flame and the outer wall of the shaft head are too close during the baking oil process, resulting in damage to the example transmission shaft due to excessive temperature; By means of the provided cotton cloth and cavity spray ring, the staff can reciprocate and horizontally push the cotton cloth, and cooperate with the cavity spray ring to evenly spray anhydrous ethanol on the repaired part of the example transmission shaft. Compared with the method of simply manually pouring anhydrous ethanol and manually wiping the repaired part of the example transmission shaft in the prior art, when the auxiliary device is used, the staff does not need to manually pour anhydrous ethanol and manually contact the cotton cloth to wipe the clean shaft head. The cotton cloth can be made to fit the repaired part of the example transmission shaft by pushing the movable plate, and reciprocate and horizontally move to fully wipe and clean the repaired part, thereby improving the efficiency of the shaft head cleaning link. At the same time, compared with the method of manually pouring anhydrous ethanol, this method can make the anhydrous ethanol contact with the repaired part of the example transmission shaft more evenly, and promote the anhydrous ethanol to fully react and contact with the stains on the repaired part, thereby improving the cleaning effect of the staff on the repaired part of the shaft head, and facilitating subsequent repair work; By cooperating with the limit grooved ring, the perforated plate, the extrusion chamber, the rod pressure plate and the adjusting bolt, when the staff is coating the repair material to the repair part of the shaft head, the adjusting bolt is used to ensure that the coating thickness of the repair material is always greater than the wear amount of the shaft head when the extrusion chamber coats the repair material along the repair part. At the same time, the stability of the circular motion of the extrusion chamber is ensured under the sliding cooperation of the limit grooved ring and the perforated plate. At the same time, compared with the prior art, the method of manually placing the repair material directly on the repair part is adopted. This method uses the extrusion chamber to accommodate the repair material, thereby reducing the accidental falling of the repair material during the coating process, thereby reducing the waste of the repair material. At the same time, the uniformity of the repair material coating process is ensured by the annular groove 2, avoiding the situation of uneven thickness, thereby ensuring the effectiveness of the shaft head repair work. The staff uses the adjustment hole and the spring lock column at the bottom of the cross bar to adjust the distance between the cross bar and the outer wall of the example transmission shaft to ensure that there is always a gap between the extrusion chamber and the outer wall of the example transmission shaft to ensure the thickness of the repair material coating. This improves the applicability of the repair auxiliary device within a certain size range and enables the coating guide limit mechanism to have the flexibility to adapt and adjust.

A threaded hole is also opened at the bottom of the adjustment plate 11 where it is inserted into the support base 1, and fastening is achieved through bolts and two threaded holes to achieve stability of the insertion part of the adjustment plate 11 and the support base 1.

[0023] Furthermore, a roasting oil guiding and stabilizing mechanism is provided above the support base 1. The roasting oil guiding and stabilizing mechanism includes a linkage bar 21 symmetrically fixedly connected to the outer wall of the bottom of the adjustment plate 11. The end of the linkage bar 21 away from the adjustment plate 11 is fixedly connected to a slotted plate 22. The slotted plate 22 is slidably connected to a vertical bar 23 through a T-shaped groove 1 provided inside. The T-shaped groove 1 is used to ensure that when the vertical bar 23 slides in the T-shaped groove 1, the vertical bar 23 will not fall off the T-shaped groove 1. The upper end of the vertical bar 23 is commonly fixedly connected to a slotted ring 24. The slotted ring 24 is slidably connected to a stabilizing slide plate 25 through an annular groove 1 provided inside. The cross section of the annular groove 1 is T-shaped, which is used to ensure that the stabilizing slide plate 25 will not fall off when sliding in the annular groove 1. The end of the stabilizing slide plate 25 away from the slotted ring 24 is fixedly connected to a stabilizing ring 28. The inside of both sides of the stabilizing ring 28 are symmetrically provided with fastening bolts 29.

The positioning pin 26 passes through the stabilizing slide plate 25 and is inserted into the interior of the pin hole plate 27. The cooperation between the two is used to locate the initial position of related components on the stabilizing slide plate 25. At the same time, when a person pulls out the positioning pin 26, the positioning pin 26 is pulled by a rope, which also facilitates subsequent personnel to insert the positioning pin 26 back into the pin hole plate 27.

[0026] Specifically, the inner surface of the stabilizing plate 210 is provided with anti-slip grooves, and the outer surface of the stabilizing plate 210 is symmetrically fixedly connected with round rods, and the round rods are slidably matched with the inner parts on both sides of the stabilizing ring 28. The fastening bolt 29 is threadedly connected to the inner parts on both sides of the stabilizing ring 28. By rotating the fastening bolt 29, under the limiting action of the round rod, the stabilizing plate 210 is driven to move horizontally toward each other, so as to clamp the outer wall of the flame-spraying end of the example roasting gun 13.

[0027] Embodiment 2 of the present invention refer to Figure 1 , Figure 2 as well as Figures 5 to 7 As shown, a cleaning auxiliary processing mechanism is arranged above the support base 1, and the cleaning auxiliary processing mechanism includes a central grooved plate 31 fixedly connected to the upper surface of the slotted plate 22, a T-shaped groove 2 is provided inside the central grooved plate 31, and a vertical plate 32 is slidably connected to the end of the T-shaped groove 2 far from the slotted plate 22, and the upper end of the vertical plate 32 is rotatably connected to a movable plate 33 through an axle body, and the part where the movable plate 33 is rotatably connected to the vertical plate 32 through the axle body is tightly matched, that is, when no external force is applied, the movable plate 33 can stably maintain the position after rotation. The lower end of the movable plate 33 is fixedly connected to a follower ring 34, and the follower ring 34 and the vertical plate 32 are fulcrums with the axle body. After rotating upward by 90 degrees, the follower ring 34 is on the same axis. The ring surface of the follower ring 34 is evenly inserted with a rod piece 37, which is composed of an arc plate and a rod body fixedly connected to the outer wall of the arc plate, and the outer wall of the rod body is sleeved with a spring 1 38, one end of the spring 1 38 is fixedly connected to the outer wall of the rod body, and the other end of the spring 1 38 is fixedly connected to the inner ring surface of the follower ring 34. Through the cooperation of the rod piece 37 and the spring 1 38, it is used to automatically adapt to the example transmission shaft 12 within a certain diameter range. Velcro is provided on the surface of the arc plate away from the rod body, and cotton cloth 39 is adhered to the Velcro. When in use, the cotton cloth 39 can be quickly replaced through the Velcro, and the cotton cloth 39 is annular, and the cotton cloth 39 is attached to the outer wall of the shaft head to effectively wipe and clean the outer wall of the repaired part of the example transmission shaft 12.

[0028] Specifically, the outer surface of the follower ring 34 close to the vertical plate 32 is fixedly connected to the cavity spray ring 35, and the outer ring surface of one side of the cavity spray ring 35 is provided with an external pipe joint 36 for connecting an external hose. The outer surface above the support base 1 is fixedly connected to a support plate, and the top surface of the support plate is fixedly connected to a liquid storage barrel 310. The upper part of the liquid storage barrel 310 is threadedly connected with a sealing cover, and the liquid storage barrel 310 is filled with anhydrous ethanol liquid. The staff can replenish anhydrous ethanol to the liquid storage barrel 310 in time by unscrewing the sealing cover. A water pump 311 is fixedly installed on the top surface of the support plate on one side of the liquid storage barrel 310. The positions of the liquid storage barrel 310 and the water pump 311 will not hinder the circular motion of the example roasting gun 13. The water inlet of the water pump 311 is connected to the bottom of the liquid storage barrel 310, and the water outlet of the water pump 311 is used for an external hose. Before use, the above-mentioned external pipe joint 36 has been connected to the water outlet of the water pump 311 by the staff through an external hose.

[0029] Specifically, the cavity spray ring 35 and the follower ring 34 are coaxially arranged, and the inner ring surface of the cavity spray ring 35 is evenly provided with nozzles for spraying anhydrous ethanol. The cavity spray ring 35 can move synchronously with the follower ring 34 and evenly spray anhydrous ethanol onto the repair part of the example transmission shaft 12 through the nozzle.

[0030] Embodiment 3 of the present invention refer to Figure 1 , Figure 2 as well as Figures 8 to 12As shown, a smearing guide limiting mechanism is arranged above the support base 1, and the smearing guide limiting mechanism includes a limiting grooved ring 41 fixedly connected to the upper surface of the vertical bar 23, and an annular groove 2 is opened inside the limiting grooved ring 41 near the vertical bar 23. A perforated plate 42 is slidably connected inside the annular groove 2, and a cross bar 43 is inserted into the inside of the perforated plate 42 away from the side of the annular groove 2, and an L-shaped rod 44 is inserted into the inside of the cross bar 43 near one end of the perforated plate 42, and the end of the cross bar 43 near the L-shaped rod 44 is a telescopic structure, specifically, the end connected with the L-shaped rod 44 is a telescopic movable rod, and the end not connected with the L-shaped rod 44 is a fixed sleeve rod, and the telescopic movable rod is movably inserted in the fixed sleeve rod, and the telescopic movable rod and the fixed sleeve rod are connected through an inner The lower end of the L-shaped rod 44 is provided with a spring 2 4401, one end of the spring 2 4401 is fixedly connected to the outer wall of the cross bar 43, and the other end of the spring 2 4401 is fixedly connected to the outer wall of the L-shaped rod 44. The outer wall of the L-shaped rod 44 away from one end of the cross bar 43 is rotatably connected with an extrusion chamber 45, and a rod pressure plate 4501 is inserted into the interior of the extrusion chamber 45. The bottom of the rod pressure plate 4501 is provided with an opening, and the side of the extrusion chamber 45 is provided with a rectangular hole for adding repair materials. When in use, the rectangular hole needs to be plugged with a sealing cover that matches the rectangular hole, and the repair material is "Sole carbon nanopolymer material". The extrusion chamber 45 and the rod pressure plate 4501 are both made of smooth silicone rubber to reduce the adhesion of the repair material. The bottom of the extrusion chamber 45 is provided with an opening for the repair material to flow out toward the outer wall of the repaired part of the example transmission shaft 12. The outer walls on both sides of the extrusion chamber 45 are symmetrically threadedly connected with adjustment bolts 46, and the bottom surfaces of the adjustment bolts 46 are all smooth planes, which are used to reduce the wear when they contact the repaired part of the exemplary transmission shaft 12.

[0031] Specifically, the cross section of the perforated plate 42 is T-shaped to ensure that the perforated plate 42 will not fall off when sliding in the annular groove 2. The part where the annular groove 2 and the perforated plate 42 are initially slidably connected are magnetically connected to each other through opposite magnetism, and the initial position and the position after use are always in this position through the magnetic connection.

[0032] Specifically, adjustment holes are evenly opened on the bottom of the cross bar 43 near the perforated plate 42, and a perforated plate 47 is fixedly connected to the bottom surface of the perforated plate 42 near the cross bar 43. A sleeve spring lock column 48 is inserted into the interior of the perforated plate 47 through a sleeve spring, and the sleeve spring lock column 48 is plugged into the adjustment hole. When in use, the staff pulls the sleeve spring lock column 48 downward and stretches the sleeve spring to make the upper end of the sleeve spring lock column 48 disengage from the adjustment hole downward, so that the cross bar 43 can move horizontally inside the perforated plate 42, and when it moves to a suitable position, the staff loosens the sleeve spring lock column 48, and under the action of the rebound force of the sleeve spring, it is automatically inserted into one of the adjustment holes, thereby ensuring that the cross bar 43 will not be easily displaced during use.

[0033] The complete working principle of the above embodiment: When using the baking oil guide stabilization mechanism, refer to Figures 1 to 4 as well as Fig.11 As shown: First, the staff moves the shaft head repair auxiliary device to the front side of the shaft head to be repaired, that is, the front side of the example transmission shaft 12, so that the slotted ring 24 is located on the periphery of the side of the shaft body to be repaired, and the center of the stabilizing ring 28 corresponds to the upper and lower part of the shaft head to be repaired. Then, according to the position of the shaft head, the staff rotates the bolts at the plug-in part of the support base 1 and the adjustment plate 11 to withdraw the threaded holes connecting the bolts and the adjustment plate 11, and then manually adjusts the upper and lower heights of the adjustment plate 11, using the slotted ring 24 as a reference, and tries to ensure that the shaft head and the slotted ring 24 are on the same horizontal axis, and then reverses the bolts to tighten the adjustment plate 11 and the support base 1.

[0034] Then, staff can follow Fig.11 As shown, by holding the example roasting gun 13, the flame-spraying end of the example roasting gun 13 is extended downward into the center of the stabilizing ring 28. At this time, the staff uses the position of the shaft head to be repaired as a reference to adaptively adjust the distance between the bottom of the flame-spraying end of the example roasting gun 13 and the shaft head to be repaired, so as to ensure that the two are within the appropriate roasting oil distance, thereby ensuring that the vertical distance between the flame and the shaft head to be repaired in the roasting oil link of the example roasting gun 13 is in a relatively constant state, avoiding the situation in which the flame and the outer wall of the shaft head are too close in the roasting oil link, and the example transmission shaft 12 is damaged due to excessive temperature. Then the staff rotates the fastening bolts 29 inside the two sides of the stabilizing ring 28 to enable the stabilizing plate 210 to move toward each other under the limiting action of the round rod, until the stabilizing plate 210 is completely attached to the outer wall of the flame-spraying end of the example roasting gun 13, and then stops rotating the fastening bolts 29, and uses the threaded connection between the fastening bolts 29 and the two sides of the stabilizing ring 28 to ensure the stability of the stabilizing plate 210 attached to the outer wall of the flame-spraying end of the example roasting gun 13; Then, if Figure 3As shown, the staff manually pulls out the positioning pin 26 upwards to make it exit the stabilizing slide plate 25 and the pin hole plate 27, and the stabilizing slide plate 25 will not be limited by the positioning pin 26 and the pin hole plate 27. Then, the staff can start the example baking gun 13 to perform oiling treatment on the repaired part of the example transmission shaft 12, and in the process of the staff holding the example baking gun 13 to perform oiling, the staff can use the example baking gun 13 that fits tightly with the stabilizing plate 210 to drive the stabilizing slide plate 25 to gradually make a circular motion along the track of the annular groove 1, so as to fully perform oiling treatment on the repaired part of the shaft head of the example transmission shaft 12.

[0035] In addition, when the staff holds the example baking gun 13 for oil baking, they can also use the example baking gun 13 to drive the slotted ring 24 and the vertical bar 23 to adjust the horizontal displacement with the T-slot 1 provided on the slotted plate 22 as the moving trajectory, so as to ensure that the flame ejected from the flame end of the example baking gun 13 can fully bake and oil the part of the shaft head of the example transmission shaft 12 to be repaired.

[0036] The effect different from the prior art in the above process is as follows: the reducer shaft head repair auxiliary device, through the slotted ring 24 and the annular groove 1, when the staff holds the example baking gun 13 to perform oil baking on the shaft head, the stabilizing plate 210 is used to indirectly fix the flame-spraying end of the example baking gun 13 to the stabilizing slide plate 25 and the stabilizing ring 28, thereby ensuring the stability and safety of the shaft head baking link of the example baking gun 13, and at the same time, the example baking gun 13 can not only make a circular motion along the annular groove 1 with the help of the stabilizing slide plate 25 to evenly perform oil baking on the shaft head repair part, but the example baking gun 13 can also move in the horizontal direction with the T-shaped groove 1 as the motion trajectory, so as to further ensure the uniformity of the shaft head baking by the staff holding the example baking gun 13. Compared with the method of simply manually holding the example baking gun 13 to bake oil in the prior art, the shaft head repair device can provide the staff with a relatively more stable and convenient operating space, thereby ensuring the effectiveness and uniformity of the staff's baking operation of holding the example baking gun 13.

[0037] When using cleaning auxiliary treatment institutions, refer to Figure 1 , Figure 2 , Fig.11 as well as Figures 5 to 7 As shown: After the staff has finished the above-mentioned oiling treatment on the repaired part of the transmission shaft 12, the staff will turn the movable plate 33 upward by 90 degrees to Fig.11As shown, the staff then applies an external force toward the repairing part of the example transmission shaft 12 by holding the movable plate 33, so that the vertical plate 32, the movable plate 33 and the rod plate 37 move along the T-slot 2 provided on the central grooved plate 31 as the movement trajectory, and synchronously move horizontally to the end face of the shaft head of the example transmission shaft 12. At this time, the staff selects a ring-shaped cotton cloth 39 of a corresponding size according to the outer diameter of the example transmission shaft 12 to be repaired. If the diameter of the shaft head to be repaired is slightly larger than Fig.11 As shown in the figure, the diameter of the example transmission shaft 12, then after the staff sticks the cotton cloth 39 on the Velcro surface of the arc plate in the rod piece 37, the part of the cotton cloth 39 that is not stuck to the Velcro will be in a wrinkled state, and then the staff continues to push the movable plate 33 horizontally. During the process, another staff member holds the outer wall of the arc plate of the rod piece 37 and applies an external force away from the center of the follower ring 34 to each rod piece 37. During the process, the spring 1 38 will be compressed, and at the same time, the wrinkled cotton cloth 39 will stretch into a circular shape. During the horizontal advancement of the movable plate 33, another staff member needs to cooperate with the staff who pushes the movable plate 33 until the rod piece 37 moves to the outer wall of the example transmission shaft 12, and the cotton cloth 39 can fit with the outer wall of the example transmission shaft 12. At this time, another staff member can loosen each rod piece 37, and the cotton cloth 39 will fit on the outer wall of the example transmission shaft 12.

[0038] Subsequently, the staff member continues to push the movable plate 33 horizontally, so that the cotton cloth 39 tends to approach the repaired part of the example transmission shaft 12. When the staff member observes that the cavity spray ring 35 is about to move to the repaired part of the example transmission shaft 12, the water pump 311 is started at this time, and the anhydrous ethanol inside the liquid storage barrel 310 is sent to the inside of the cavity spray ring 35 through the external hose. The anhydrous ethanol is evenly sprayed toward the center of the cavity spray ring 35 through the nozzles evenly arranged on the inner ring surface of the cavity spray ring 35, and then the staff member needs to slowly push the movable plate 33 horizontally, so that the anhydrous ethanol is evenly and fully sprayed on the repaired part of the example transmission shaft 12. The staff member can push the movable plate 33 horizontally back and forth, so that the cotton cloth 39 is close to the repaired part of the example transmission shaft 12, and reciprocatingly wipes the part. In the process, it is necessary to intermittently spray the anhydrous ethanol inside the liquid storage barrel 310 on the repaired part of the example transmission shaft 12 through the water pump 311, depending on the situation, to ensure that the anhydrous ethanol can fully contact the shaft head for cleaning.

[0039] Supplementary explanation: In the process of sticking the cotton cloth 39, if the diameter of the cotton cloth 39 is the same as the diameter of the shaft head to be repaired, Fig.11When the two shafts are matched, the staff can directly push the movable plate 33 to make the cotton cloth 39 fit the outer wall of the shaft head. If the diameter of the shaft body to be repaired is much larger than the maximum adaptability range of the rod piece 37 or much smaller than the adaptability range of the rod piece 37, then it is necessary to use a shaft head repair auxiliary device with a larger or smaller overall size specification. The shaft head repair auxiliary device schematically illustrated in this embodiment can automatically adapt to shaft heads to be repaired of different diameters within a certain range.

[0040] When the staff has finished wiping and cleaning the repaired part, the water pump 311 is turned off to stop delivering anhydrous ethanol. At this time, the staff manually moves the movable plate 33 in the opposite direction to reset it, so that the cotton cloth 39 and the cavity spray ring 35 and other components are restored to the original state. Figure 1 In the initial state shown, the cotton cloth 39 adhering to the surface of the Velcro of the arc plate in the rod piece 37 can be manually removed, and the surface cleaning work of the repaired part of the shaft head is completed.

[0041] The effect different from the prior art in the above process is as follows: the reducer shaft head repair device, through the provided cotton cloth 39 and the cavity spray ring 35, the staff reciprocates and horizontally pushes the cotton cloth 39, and cooperates with the cavity spray ring 35 to evenly spray anhydrous ethanol on the repair part of the example transmission shaft 12. Compared with the prior art method of simply manually pouring anhydrous ethanol and manually wiping the repair part of the example transmission shaft 12, when the auxiliary device is used, the staff does not need to manually pour anhydrous ethanol and manually contact the cotton cloth 39 to wipe the shaft head. By pushing the movable plate 33, the cotton cloth 39 can be attached to the repair part of the example transmission shaft 12, and reciprocated horizontally displaced to fully wipe and clean the repair part, thereby improving the efficiency of the shaft head cleaning link. At the same time, compared with the method of manually pouring anhydrous ethanol, this method can make the anhydrous ethanol contact with the repair part of the example transmission shaft 12 more evenly, prompting the anhydrous ethanol to fully react and contact with the stains on the repair part, thereby improving the cleaning effect of the staff in handling the shaft head repair part, and facilitating subsequent repair work.

[0042] When applying the guide limiter, Figure 1 , Figure 2 as well as Figures 8 to 11 As shown: After the cleaning of the repaired part of the shaft head is completed, the staff completely removes the liquid and impurities on the surface of the repaired part. Then, the staff pulls the sleeve spring lock column 48 downward to move it out of the adjustment hole, and manually moves the cross bar 43 horizontally along the part where it is plugged into the perforated plate 42 toward the outer wall of the example transmission shaft 12, while driving the L-shaped rod 44 to make the extrusion chamber 45 and the rod pressure plate 4501 move synchronously until the extrusion chamber 45 moves to the position as shown in the figure. Fig.11 and Fig.12In the state shown, the lower end surface of the adjusting bolt 46 is in contact with the unrepaired portion of the example transmission shaft 12, and then the sleeve spring lock column 48 is inserted back into the adjusting hole to fix the moved cross bar 43 and the L-shaped rod 44.

[0043] Then, the staff measured the wear size of the shaft head in advance and calculated the amount of repair material to be applied to the repaired part of the example transmission shaft 12. Then, the staff held the L-shaped rod 44 upward to compress the spring 2 4401. At this time, the material extrusion chamber 45 and the two adjustment bolts 46 did not contact the outer wall of the example transmission shaft 12. Then, the staff rotated the two adjustment bolts 46. As the adjustment bolts 46 rotated, the adjustment bolts 46 moved downward so that their lower ends were in contact with the outer wall of the example transmission shaft 12. At this time, the adjustment bolts 46 were stopped to ensure that a certain distance was left between the bottom of the material extrusion chamber 45 and the outer wall of the example transmission shaft 12, so as to ensure that the thickness of the repair material applied later could be greater than the wear amount of the shaft head.

[0044] Then, the staff will put some repair materials into the extrusion chamber 45, and insert the sealing cover on the rectangular hole to prevent the repair materials from flowing out of the rectangular hole. Afterwards, the staff can hold the extrusion chamber 45, apply an external force greater than the magnetic attraction of the magnetic attraction parts of the perforated plate 42 and the limiting groove ring 41, so that the extrusion chamber 45 moves in a circle, and simultaneously enables the perforated plate 42 to start moving in this direction along the trajectory of the annular groove 2. At the same time, during the movement of the extrusion chamber 45, the staff presses down the rod pressure plate 4501 by hand to cause the repair materials inside the extrusion chamber 45 to flow out from the opening at the bottom thereof. For details, refer to Fig.10 , to ensure that the repair material can be effectively adhered to the outer wall of the exemplary transmission shaft 12 in a timely manner, so that as the perforated plate 42 moves, the repair material can be applied to the repaired part of the shaft head. Fig. 9 and Fig.12As shown, during the circular motion of the extrusion chamber 45, the staff holds the extrusion chamber 45 and rotates it with the L-shaped rod 44 as a fulcrum, thereby ensuring that the bottom of the extrusion chamber 45 always corresponds to the outer wall of the example transmission shaft 12. At the same time, when the L-shaped rod 44 gradually moves to the bottom of the example transmission shaft 12, the telescopic structure of the L-shaped rod 44 will shrink and cause the built-in spring to be compressed. When the telescopic structure gradually returns to the top of the example transmission shaft 12, the rebound force of the built-in spring will drive the telescopic movable rod to gradually slide in the opposite direction and reset. If the width of the repaired portion of the transmission shaft 12 is greater than the width of the extrusion chamber 45, the staff will hold the extrusion chamber 45 and make circular motions to apply the repair material to a part of the repaired portion first, and then apply a horizontal external force toward the direction close to the cross bar 43 by holding the extrusion chamber 45, so as to cause the extrusion chamber 45 and the rod pressure plate 4501, the perforated plate 42 and the limiting groove ring 41 to move horizontally along the T-groove as the vertical bar 23, so as to apply the repair material to the next part to be repaired.

[0045] During the coating process, since the rod pressure plate 4501 and the extrusion chamber 45 are made of silicone rubber with a smooth surface, after the repair material is placed in the extrusion chamber 45, the adhesion of the repair material to its inner wall can be minimized, so that the repair material can be fully coated on the outer wall of the repaired part of the example transmission shaft 12, and by opening the sealing cover, the amount of repair material used inside can be intuitively seen, which is convenient for the staff to replenish the repair material in time.

[0046] In addition, if the diameter size of the shaft head part to be repaired is much larger than the use range of the extrusion chamber 45 and the rod pressure plate 4501 in this embodiment, it is necessary to use an shaft head auxiliary repair device with a larger overall size. If the diameter size of the repaired part is only slightly larger than the use size of the two, that is, within the use range indicated in this embodiment, the staff can adjust the distance between the cross bar 43 and the outer wall of the example transmission shaft 12 through the adjustment hole at the bottom of the cross bar 43 and the sleeve spring lock column 48 to ensure that there is always a gap between the extrusion chamber 45 and the outer wall of the example transmission shaft 12 to ensure the thickness of the repair material coating, thereby improving the applicability of the repair auxiliary device within a certain size range and enabling the coating guide limit mechanism to have the flexibility to adapt and adjust.

[0047] Finally, when the staff has finished applying the repair material, the staff will withdraw the sleeve spring lock column 48 from the adjustment hole, and then the extrusion chamber 45 can be reset to its initial state, and the auxiliary device will be removed from the example transmission shaft 12, thus completing some steps of the shaft head repair work.

[0048] The effect of the above process is different from that of the prior art: the reducer shaft repair auxiliary device, through the cooperation of the set limiting grooved ring 41, the perforated plate 42 and the extrusion chamber 45, the rod pressure plate 4501 and the adjusting bolt 46, during the process of the staff coating the repair material to the repair part of the shaft head, ensures through the adjusting bolt 46 that when the extrusion chamber 45 coats the repair material along the repair part, the coating thickness of the repair material is always greater than the wear amount of the shaft head, and at the same time, under the sliding cooperation of the limiting grooved ring 41 and the perforated plate 42, the stability of the circular motion of the extrusion chamber 45 is ensured. At the same time, compared with the prior art, the method of manually placing the repair material directly on the repair part is adopted. This method uses the extrusion chamber 45 to accommodate the repair material, thereby reducing the accidental falling of the repair material during the coating process, thereby reducing the waste of repair materials, and at the same time, the uniformity of the repair material coating process is ensured through the annular groove 2 to avoid the situation of uneven thickness, thereby ensuring the effectiveness of the shaft head repair work.
