Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder plunger processing technology, and in particular to a bearing device for hydraulic cylinder plunger painting processing. Background Technology

[0002] A plunger cylinder is a type of hydraulic cylinder; a single plunger cylinder can only move in one direction, requiring external force to reverse. Two plunger cylinders combined can also achieve reciprocating motion using pressurized oil. During movement, the plunger cylinder is guided by a guide sleeve on the cylinder head, therefore the inner wall of the cylinder barrel does not require precision machining. It is particularly suitable for applications with long strokes. Furthermore, plunger cylinders are further divided into radial plunger cylinders and axial plunger cylinders.

[0003] In order to increase the wear resistance of the plunger in the plunger cylinder, the plunger surface needs to be coated with paint and wear-resistant paint during the production process. However, the existing painting equipment is not convenient to spray while the plunger is rotating, which can easily lead to uneven coating and poor paint quality. Utility Model Content

[0005] A bearing device for painting hydraulic cylinder plungers includes a worktable and a limiting mechanism and a driving mechanism mounted on the worktable. The limiting mechanism includes a fixed seat, a movable seat, a limiting rod, an electric cylinder, a limiting part, a support, an adjusting component, a pressure-applying end, and an adjusting bolt. The fixed seat is fixed on the worktable. The movable seat is inserted into one end plate of the worktable via the limiting rod, which helps the movable seat slide against the surface of the worktable. The electric cylinder is also mounted on the end plate of the worktable, and its output end is fixedly connected to the movable seat. At least one set of limiting parts is rotatably mounted on both the fixed seat and the movable seat. The support is correspondingly disposed at the opening of the limiting part and is mounted on the fixed seat and the movable seat respectively via the adjusting component. The adjusting bolt is rotatably mounted on the fixed seat and the movable seat respectively and passes through the middle of the limiting part. The pressure-applying end is rotatably mounted at the end of the adjusting bolt.

[0006] The drive mechanism is mounted on a fixed base and includes a connecting base, a motor, a lead screw, a slide, a rack, and...

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0024] Referring to Figures 1-2, a bearing device for painting hydraulic cylinder plungers includes a worktable 1 and a limiting mechanism and a driving mechanism mounted on the worktable 1. The limiting mechanism includes a fixed seat 2, a movable seat 3, a limiting rod 4, an electric cylinder 5, a limiting part 12, a support platform 13, an adjusting component 14, a pressure end 15, and an adjusting bolt 16. The fixed seat 2 is fixed to the worktable 1. The movable seat 3 is inserted into one end plate of the worktable 1 via the limiting rod 4, which helps the movable seat 3 slide against the surface of the worktable 1. The electric cylinder 5 is also mounted on the end plate of the worktable 1, and its output end is fixedly connected to the movable seat 3. At least one set of limiting parts 12 is rotatably mounted on both the fixed seat 2 and the movable seat 3. The support platform 13 is correspondingly disposed at the opening of the limiting part 12 and is mounted on the fixed seat 2 and the movable seat 3 respectively via the adjusting component 14. The adjusting bolt 16 is rotatably mounted on the fixed seat 2 and the movable seat 3 respectively and passes through the limiting part 12. In the middle, the pressure-applying end 15 is rotatably mounted at the end of the adjusting bolt 16;

[0025] The drive mechanism is mounted on the fixed base 2 and includes a connecting seat 6, a motor 7, a lead screw 8, a slide 9, a rack 10, and a gear ring 11. The connecting seat 6 and the motor 7 are both mounted on the top surface of the fixed base 2. The lead screw 8 is fixedly mounted at the output end of the motor 7. The slide 9 is connected to the lead screw 8 and moves along the groove of the connecting seat 6.

[0026] The rack 10 moves, and one side slides along the connecting seat 6 and is fixedly connected to the slide seat 9. The toothed ring 11 is fixedly installed on the outer wall of the connecting sleeve between the limiting part 12 and the fixed seat 2, and is engaged with the toothed ring 11 for transmission.

[0027] The support platform 13 has an arc-shaped structure, and ball bearings are arranged on the concave arc surface of the support platform 13. According to the length of the plunger, the electric cylinder 5 can be driven to push the moving seat 3 to a suitable position, and the height of the support platform 13 can be adjusted so that when the plunger is placed horizontally, the central axis of the plunger and the central axis of the limiting part 12 are on the same horizontal straight line. Then, the electric cylinder 5 can be driven to push the moving seat 3, and the limiting part 12 on the fixed seat 2 and the limiting part 12 on the moving seat 3 can be used to apply pressure to both ends of the plunger to clamp the plunger. Then, the adjusting bolt 16 can be rotated to push the pressure end 15 to fit tightly against the end face of the plunger, further enhancing the stability of the plunger limiting.

[0028] Then the motor 7 can drive the slide 9 to move through the lead screw 8. The slide 9 then pushes the rack 10 to slide along the connecting seat 6. At the same time, the rack 10 drives the gear ring 11 to rotate. The gear ring 11 drives the plunger to rotate through the limiting part 12. During the rotation of the plunger, the plunger can be painted by external painting equipment.

[0029] Because the surface of the workbench 1 is equipped with a guide channel, excess paint can flow to the collection tanks 101 on both sides of the workbench 1 for collection.

[0030] This device can quickly adjust and position plungers of different sizes, and rotates automatically during the painting process to facilitate more uniform paint application to the plungers.

[0031] The upper surface of the workbench 1 is provided with a flow guide channel, and collection tanks 101 are also installed on both sides of the workbench 1. The flow guide channel is arranged to gradually slope downward from the middle of the workbench 1 to both sides, so that the paint liquid can flow into the collection tanks 101 for collection.

[0032] The opening of the limiting part 12 is a slot with a frustum structure, and a through hole is opened in the middle of the limiting part 12. The diameter of the through hole is larger than the diameter of the pressure end 15, and the diameter of the pressure end 15 is larger than the diameter of the adjusting bolt 16. This is to allow the end of the plunger to be locked in the opening of the limiting part 12 for limiting, so as to prevent the plunger from moving after being clamped, which would affect the normal rotation of the plunger and the spraying.

[0033] The center point of the limiting part 12 on each fixed seat 2 and the center point of the limiting part 12 on the corresponding movable seat 3 are on the same straight line; so as to place the plunger horizontally and clamp and limit it, so as to facilitate the subsequent clamping and stable rotation of the plunger, and to spray it with paint by external painting equipment.

[0034] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
