Description

Technical Field

[0001] The utility model relates to the field of return plate processing equipment, in particular to a multi-station return plate positioning device. Background Art

[0002] The return plate is a disc-shaped component in the axial piston pump. It forms a return device together with the return spring and steel ball when the piston pump sucks oil. The sliding shoe can be pressed tightly against the surface of the inclined plate to slide, realizing the self-priming ability of the pump. When the plunger returns, the return plate will control the position of the plunger in time so that it can smoothly return to the initial position and prepare for the next work. The processing method of the return plate mainly includes mixing, stamping, heating forging, punching and surface treatment, etc., in order to ensure that it has good strength, wear resistance and service life.

[0003] The existing devices for positioning the return disk during its processing can mostly only position one return disk at a time. As the continuous processing operation of multiple return disks is carried out, it is necessary to repeatedly perform loading and unloading operations on different return disks, and it is necessary to repeatedly operate the clamps compatible with the return disks. The operation process is relatively cumbersome. If the operation deviates, it is easy to affect the stability of the return disk during the processing, thereby reducing the processing efficiency. Utility Model Content

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a multi-station return disk positioning device, comprising a placing plate on which the return disk can be placed and a bottom plate located directly below the placing plate, wherein the placing plate is provided with a plurality of stations that can accommodate the return disk, and a plurality of cylinders are provided in the plurality of angle spaces formed by the placing plate and the bottom plate, and the plurality of cylinders are respectively located below the plurality of stations.

[0006] It also includes a plurality of pressure claws arranged on the work station. In a natural state, the plurality of pressure claws are equidistantly distributed along the annular trajectory of the return disk body. The pressure claws are each provided with a connecting rod structure that cooperates with the cylinder, and the connecting rod structure is used to adjust the connection state between the pressure claw and the return disk.

[0007] Furthermore, the connecting rod structure includes a first push rod and a second push rod arranged from the inside to the outside along the distribution direction of the pressure claws, and the bottom end of the second push rod is connected to a lifting and lowering engagement block through a rotating shaft, and the engagement block is connected to the first push rod through a driving rod, and the bottom end of the first push rod is connected to a positioning rod through a rotating shaft.

[0008] The positioning rod is always in a vertical state. When the engagement block rises, the driving rod can push the first push rod to rotate in place, and the second push rod rotates in the process of synchronously rising with the engagement block until the pressure claw abuts against the surface of the return disk.

[0009] Furthermore, a plurality of engagement blocks located at the same station are all connected to the same linkage plate, and the linkage plate is arranged on the cylinder output shaft of the station.

[0010] Furthermore, the bottom ends of the plurality of positioning rods located at the same workstation are connected to the same connecting plate, and the connecting plate is arranged on the cylinder of the workstation.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: Reference Figure 1-3 A multi-station return disk positioning device is shown, comprising a placing plate 1 on which the return disk can be placed and a bottom plate 2 located directly below the placing plate 1, wherein the placing plate 1 is provided with a plurality of stations for accommodating the return disk, and a plurality of cylinders 3 are provided in the plurality of angle spaces formed by the placing plate 1 and the bottom plate 2, and the plurality of cylinders 3 are respectively located below the plurality of stations.

[0025] It also includes a plurality of pressure claws 4 arranged on the workstation. In the natural state, the plurality of pressure claws 4 are evenly distributed along the annular track of the return disk body. The pressure claws 4 are provided with a connecting rod structure that cooperates with the cylinder 3. The connecting rod structure is used to adjust the connection state between the pressure claws 4 and the return disk. When the pressure claws 4 bite the surface of the return disk under the action of the cylinder 3 and the connecting rod structure, the stability of the return disk can be maintained, so as to facilitate the processing operation of the return disk. Moreover, in the present application document, the plurality of workstations are evenly distributed, and the plurality of return disks can be positioned at the same time, so as to maintain the stability of the return disk and improve the processing efficiency of the return disk.

[0026] like Figure 4-6 As shown, the connecting rod structure includes a first push rod 5 and a second push rod 6 arranged from the inside to the outside along the distribution direction of the pressure claw 4. The bottom end of the second push rod 6 is connected to a lifting and lowering movable block 71 through a rotating shaft. The engaging block 71 is connected to the first push rod 5 through a driving rod 8. The bottom end of the first push rod 5 is connected to a positioning rod 51 through a rotating shaft.

[0027] The positioning rod 51 is always in a vertical state. When the engagement block 71 rises, since the two ends of the driving rod 8 are respectively connected to the first push rod 5 and the engagement block 71 through the rotating shaft, the driving rod 8 can push the first push rod 5 to rotate in place around the rotating shaft connected to the positioning rod 51. At the same time, the second push rod 6 rotates in the process of synchronously rising with the engagement block 71, so as to achieve the purpose of driving the pressure claw 4 to flexibly engage with the surface of the return plate.

[0028] When the pressure claw 4 abuts against the surface of the return disk, the range of movement of the pressure claw 4 is small, and the return disk can be quickly positioned. Since the pressure claw 4 is evenly distributed along the circular track of the return disk body, the distribution of the pressure claw 4 at multiple points can evenly and synchronously position multiple points on the return disk, effectively avoiding the shaking phenomenon caused by uneven force on the return disk during positioning, and improving the stability of the return disk.

[0029] like Figure 5 , Figure 6 As shown, in order to maintain the consistency of the multiple tether blocks 71 in the rising and falling states, the multiple tether blocks 71 located at the same station are all connected to the same linkage plate 7, which is arranged on the output shaft of the cylinder 3 at the station. When the cylinder 3 is running, the linkage plate 7 and the tether blocks 71 can be controlled to rise and fall synchronously.

[0030] like Figure 4 As shown, in order to maintain the stability of the positioning rod 51 and prevent the positioning rod 51 from loosening and thus affecting the accuracy of the first push rod 5 in the moving state, the bottom ends of the multiple positioning rods 51 located at the same station are connected to the same adapter plate 52, and the adapter plate 52 is arranged on the cylinder 3 of the station. The cylinder 3 and the adapter plate 52 are both in a stable state.

[0031] like Figure 3 As shown, in order to maintain the stability of the return disk and facilitate confirmation of the placement position of the return disk, a plurality of limiting grooves 11 for accommodating the return disk are opened on the surface of the placing plate 1, and through holes 12 corresponding to the process holes of the return disk are opened in the limiting grooves 11 to facilitate processing of the process holes of the return disk at the work station, so that processing debris powder and debris can be discharged smoothly.

[0032] like Figure 3 As shown, in order to allow a certain gap to exist between the return disc and the inner bottom wall of the limiting groove 11 so as to facilitate the staff to pick up the return disc, a gasket 13 is provided in the limiting groove 11. In a natural state, the return disc inserted into the limiting groove 11 fits on the gasket 13. When the return disc is processed, it is convenient to pick up the return disc.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
