DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1

[0023] The embodiment of the present application provides a hydraulic cylinder body grinding support device, such as Figures 1 to 4 As shown, it includes: an inner supporting mechanism 1, an outer supporting mechanism 2, and a base 3.

[0024] Among them, the inner support mechanism 1 includes a movable shaft 11 horizontally arranged above the base 3 and movable along its own axis. A mounting sleeve 12 is coaxially sleeved on the movable shaft 11. A support plate 13 is vertically provided at one end of the movable shaft 11. An axial hole 133 adapted to the axial diameter of the movable shaft 11 is provided on the support plate 13. At least two guide holes 131 uniformly arranged in an array around the circumference of the movable shaft 11 are also provided on the support plate 13. A number of inner support plates 14 adapted to the guide holes 131 and uniformly arranged around the circumference of the movable shaft 11 and facing the axis of the movable shaft 11 are provided on the circumference of the mounting sleeve 12. One end of the inner support plate 14 fits in the guide hole 131. A transmission member 15 is provided between the inner support plate 14 and the mounting sleeve 12 for making the inner support plate 14 As the movable shaft 11 moves, it contracts or expands along the guide hole 131, moving closer to or away from the axis of the movable shaft 11; the external support mechanism 2 is arranged below the internal support mechanism 1, and includes support wheels 21 located on both sides of the movable shaft 11 and with axes parallel to the axis of the movable shaft 11. Accordingly, multiple groups of support wheels 21 can be provided and arranged in an array along the axis of the movable shaft 11 to improve the stability of the hydraulic cylinder support; a movable plate 31 is provided at one end of the base 3, which is movably arranged along the axis of the movable shaft 11, the support plate 13 is provided on the movable plate 31, and the support wheel 21 is provided at the other end of the base. Accordingly, a support frame 32 is also provided on the movable plate 31, and a linear mechanism 4 is provided on the support frame 32, and its movable end is coaxially connected to one end of the movable shaft 11.

[0025] When applied, such as Figure 5As shown, the welded hydraulic cylinder body is hoisted and placed on the support wheel 21 of the outer support mechanism 2, and the base of the cylinder body is directed toward the inner support mechanism 1. At this time, the support wheels 21 are located on both sides of the bottom of the cylinder body to provide preliminary support for it, and the axis of the cylinder body and the axis of the movable shaft 11 remain coincident; the movable plate 31 is pushed toward the cylinder body to drive the movable shaft 11 into the cylinder body, and the axis of the cylinder body and the axis of the movable shaft 11 remain coincident; the linear mechanism 4 drives the movable shaft 11 to move along its own axis and pass through the support plate 13. Under the action of the transmission member 15 and the guide hole 131, the inner support plate 14 is made to expand along the guide hole 131 away from the axis of the movable shaft 11 until The inner support plate 14 abuts against the inner wall of the cylinder body, thereby further supporting the cylinder body. At this time, the cylinder body has a high stability, and the welds and corners of the cylinder body can be polished and trimmed. When it is necessary to polish other parts of the cylinder body, the linear mechanism 4 drives the movable shaft 11 to move in the opposite direction, so that the inner support plate 14 moves along the guide hole 131 to contract close to the movable shaft 11. The inner support plate 14 releases its support for the inner wall of the cylinder body. Under the action of the support wheel 21, the cylinder body can rotate around its own axis, and the cylinder body can be turned to a position convenient for polishing. Then the movable shaft 11 is driven to move, so that the inner support plate 14 abuts against the inner wall of the cylinder body again for support, and then polishing can be continued. Through the arrangement of the inner support mechanism 1 and the outer support mechanism 2, the hydraulic cylinder body polishing method is improved, and the support stability of the hydraulic cylinder body and the convenience of adjusting the cylinder body polishing position are effectively improved, which is beneficial to the cylinder body polishing efficiency.

[0026] As a preferred structure, Figure 4 As shown, the inner support plate 14 is an arc-shaped plate adapted to the inner wall of the cylinder body, and a layer of flexible anti-skid pad is attached to the plate surface, which can increase the friction between the inner support plate 14 and the inner wall of the cylinder body, further improve the support stability, and effectively prevent the inner support plate 14 from scratching the inner wall of the cylinder body.

[0027] Specifically, such as Figure 2 and Figure 4As shown, the transmission member 15 includes a mounting bar 151 provided on the mounting sleeve 12 and arranged toward the axis of the mounting sleeve 12. The number of the mounting bars 151 matches the inner support plate 14 and is evenly arranged around the circumference of the movable shaft 11. The inner side of the inner support plate 14 is connected to a movable rod 152 arranged toward the axis of the movable shaft 11. The plane formed by the axis of each movable rod 152 and the axis of the corresponding mounting bar 151 passes through the axis of the movable shaft 11. A pair of parallel connecting rods 153 are provided between each movable rod 152 and the corresponding mounting bar 151. The two ends of the two connecting rods 153 are respectively hinged to the mounting bar 15 1 and the corresponding movable rod 152, the rotation axes of the mounting bars 151 on both sides are collinear and perpendicular to the axis of the movable shaft 11, and the rotation axes of the movable rod 152 on both sides are collinear and perpendicular to the axis of the movable shaft 11; the guide hole 131 is a strip-shaped hole, and the strip holes are all arranged toward the axis of the guide hole 131. A matching shaft 154 is coaxially provided at one end of the movable rod 152, and a pair of limiting rings 155 are coaxially provided on the matching shaft 154. The matching shaft 154 between the two limiting rings 155 is fitted in the guide hole 131, and the two limiting rings 155 respectively abut against the two sides of the support plate 13. The movable end of the linear mechanism 4 drives the movable shaft 11 to retract and one end of the connecting rod 153 to move along the axis of the movable shaft 11. Due to the hinged arrangement at both ends of the connecting rod 153 and the cooperation between the mating shaft 154 and the guide hole 131, and the two limiting rings 155 respectively abutting the two sides of the support plate 13, the connecting rod 153 gradually becomes perpendicular to the axis of the movable shaft 11. One end of the connecting rod 153 abuts the movable rod 153 and moves away from the axis of the movable shaft 11, thereby achieving the expansion movement of the inner support plate 14. When the movable end of the linear mechanism 4 drives the movable shaft 11 to extend, the hinged connection of the connecting rod 153 and the cooperation between the mating shaft 154 and the guide hole 131 enable the contraction movement of the inner support plate 14. The arrangement of the mounting bar 151 and the movable rod 152, in conjunction with the connecting rod 153 and the driving mechanism 4, achieves the contraction and expansion movement of the inner support plate 14, thereby optimizing the structure of the device.

[0028] Specifically, such as Figures 1 to 4 As shown, there are three guide holes 131 , and accordingly, there are three inner support plates 14 and three mounting bars 151 . The three inner support plates 14 can meet the requirement of uniformly supporting the circumference of the inner wall of the cylinder body and have high stability.

[0029] Specifically, such as Figure 4 As shown, there are multiple pairs of connecting rods 153 between each movable rod 152 and the corresponding mounting bar 151, and they are arranged in an array along the axis of the movable rod 152. Providing multiple pairs of connecting rods 153 can effectively prevent movement interference between the movable rod 152 and the mounting bar 151, thereby improving the reliability of the device.

[0030] Example 2

[0031] As a further embodiment of Example 1, Figure 1 and Figure 3 As shown, the mounting sleeve 12 is coaxially rotatably sleeved on one end of the movable shaft 11, and a rotating ring 16 is coaxially rotatably sleeved on the mating shaft 154 between the two limit rings 155. The rotating ring 16 is fitted into the guide hole 131, and arc-shaped holes 132 whose number is consistent with the guide holes 131 and is adapted to the rotating ring 16 are opened along the circumference of the support plate 13. One end of each arc-shaped hole 132 is respectively connected to the end of the corresponding guide hole 131. During operation, the inner support plate 14 moves along the guide hole 131 to expand. When the inner support plate 14 abuts against the inner wall of the cylinder for support, the rotating ring 16 also moves to the end of the guide hole 131. Because the mounting sleeve 12 is coaxially rotatably mounted on one end of the movable shaft 11, the rotating ring 16 cooperates with the arcuate hole 132, and the friction between the inner support plate 14 and the inner wall of the cylinder allows the rotating ring 16 to rotate into the arcuate hole 132 when a force is applied to the cylinder body along the tangent direction of its outer circle. The mounting sleeve 12 rotates on the movable shaft 11, and the cylinder body rotates about its own axis. Under the action of the mounting sleeve 12, the rotating ring 16, and the arcuate hole 132, the device not only provides relatively stable support for the hydraulic cylinder body, but also allows the grinding position of the cylinder body to be adjusted while maintaining stable support, which is highly convenient and further improves grinding efficiency.

[0032] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
