Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil cylinder plunger production, in particular to a bearing frame used for the production of hydraulic oil cylinder plungers. Background Art

[0002] A plunger-type hydraulic cylinder consists of a gland, sealing ring, guide sleeve, plunger, and cylinder barrel. It can only achieve unidirectional motion, with the return stroke driven by gravity, spring force, or other external forces. To achieve bidirectional motion, it is typically used in pairs, arranged in opposite directions. Because the plunger and guide sleeve work together to ensure good guidance, the plunger does not contact the inner wall of the cylinder barrel. Therefore, the inner wall precision requirements are very low, and even machining is unnecessary. This offers excellent processability and low cost, making it particularly suitable for applications with long strokes.

[0003] After production, the hydraulic cylinder plunger is usually placed directly on a flat plate rack. During the picking and placing process, it is easy to cause collisions with each other, resulting in damage to the plunger. During the moving and transferring process, the plunger will also be damaged. Utility Model Content

[0015] The beneficial effects of the support frame used in the production of hydraulic cylinder plungers of the utility model are:

[0016] The two ends of the plunger are respectively placed in a placement groove corresponding to the position of the two sets of rotating disks, supported by the pressure plate, and the hand wheel is manually turned, while the rotating disk rotates inside the fixed ring plate, applying a certain pressure to the plunger, and squeezing the spring through the pressure plate. At this time, the plunger moves to the inner circle of the fixed ring plate, and the opening of the placement groove is restricted by the fixed ring plate, and the plunger is placed; subsequently, the plunger can be placed in the placement groove according to the above operation; similarly, when removing the plunger, it is only necessary to move the plunger to the position of the pick-and-place port to remove the plunger, which is convenient for taking and placing the plunger, and the plunger is stably restricted to avoid contact between the plungers and damage.

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with 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 making a clearer and more precise definition of the protection scope of the present invention.

[0022] Reference Figure 1-3 , a bearing frame for the production of hydraulic cylinder plungers, including opposing bases 1, a roller 2 installed at the bottom of the base 1 and a bearing mechanism installed on the two bases 1, the bearing mechanism including a fixed ring plate 3, a rotating disk 4, a connecting shaft 5, a baffle 7, a pressure plate 8 and a spring 9, there are two fixed ring plates 3, which are respectively installed on the two bases 1, the rotating disk 4 is limited to the inner ring of the fixed ring plate 3 by a slide groove 402, and rotates along the track plate 301 of the inner ring of the fixed ring plate 3, the connecting shaft 5 is installed between the two rotating disks 4, the baffle 7 is installed at one side of one group of rotating disks 4, there are multiple pressure plates 8, which are installed one by one in the multiple placement grooves 401 opened at the edge of the rotating disk 4 through springs 9.

[0023] A hand wheel 6 is installed on one side of the other set of rotating disks 4; the hand wheel 6 can be turned to control the synchronous rotation of the two rotating disks 4, which is convenient for the staff to put the plunger into the placement slot 401 and to facilitate the subsequent removal of the plunger.

[0024] Both fixed ring plates 3 are provided with a pick-up and placement port 303, and a connecting plate 10 is commonly installed at the bottom end of the pick-up and placement port 303 of the two fixed ring plates 3; by moving one of the placement slots 401 of the rotating disk 4 to the pick-up and placement port 303, the plunger can be placed in the placement slot 401, or removed from the placement slot 401. The plunger that has been placed can be subsequently moved to the inner ring of the fixed ring plate 3 by rotating the rotating disk 4, so that the plunger can be restricted. When the device is subsequently moved, the plunger always remains in a stable state.

[0025] A rubber pad 302 is also installed on the inner ring of the track plate 301; the contour of the slide groove 402 is adapted to the track plate 301 and the rubber pad 302, and the track plate 301 slides in the slide groove 402, and the rubber pad 302 is not arranged at the connection with the slide groove 402; the rubber pad 302 and the pressure plate 8 cooperate to stabilize the plunger in the placement groove 401, and the setting of the rubber pad 302 can avoid hard contact between the fixed ring plate 3 and the plunger, causing damage to the plunger.

[0026] Working principle: When in use, the device can be pushed to a predetermined position so that the two ends of the plunger are respectively placed in a placement groove 401 corresponding to the position of the two sets of rotating disks 4. (It should be noted that when placing, the end with the larger diameter is placed close to the baffle 7 to prevent the plunger from sliding out of the placement groove 401 laterally). The bottom of the plunger is supported by the pressure plate 8. After the placement is completed, the hand wheel 6 is manually turned, and the rotating disk 4 rotates inside the fixed ring plate 3, applying a certain pressure to the plunger. The spring 9 is squeezed through the pressure plate 8. At this time, the plunger moves to the inner ring of the fixed ring plate 3, and the opening of the placement groove 401 is restricted by the fixed ring plate 3, and the plunger is placed.

[0027] Subsequently, the plunger is placed in the placement groove 401 according to the above operation. Similarly, when removing the plunger, the plunger only needs to be moved to the position of the access port 303 to remove the plunger.

[0028] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
