Description

Technical Field

[0001] The utility model specifically relates to the technical field of automated clamp equipment, in particular to a clamp which is convenient for positioning and clamping a small master cylinder. Background Art

[0002] Hydraulic transmission is widely used in civil engineering and mechanical engineering. The assembly accuracy of parts in hydraulic system is very high, especially the inner diameter of cylinder body. Whether the hydraulic system can withstand high pressure, the bearing capacity of main cylinder body is very important. Figure 5 Currently, a small master cylinder needs to be matched with a CNC milling machine to finely mill the inner hole. The existing workbench has a single clamping fixture. For this type of small master cylinder, a special high-precision positioning fixture is required, and it is convenient for CNC machine tools to perform milling processing at multiple stations at the same time to increase production and sales. Utility Model Content

[0003] The purpose of the utility model is to solve the problem that the small master cylinder in the background technology needs to cooperate with the CNC milling machine to finely mill the inner hole, while the existing workbench has a single clamping fixture and it is convenient for the CNC machine tool to implement milling processing at multiple stations at the same time. We design a small master cylinder hydraulic four-axis clamp that can implement synchronous positioning and clamping at multiple stations.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A multi-station small master cylinder hydraulic four-axis clamp, comprising a dislocation synchronous positioning slide and a plurality of four-axis clamping components.

[0006] The offset synchronous positioning slide comprises a slider rail assembly, a positioning carrier plate and a push hydraulic cylinder arranged in a central symmetrical manner. The hydraulic rod of the push hydraulic cylinder drives the positioning carrier plates on both sides to slide in an offset manner, and with the assistance of the slider rail assembly, the straightness and position dimension accuracy of the offset sliding are ensured. The positioning carrier plate is provided with a positioning block that cooperates with the four-axis clamping assembly.

[0007] The four-axis clamping assembly includes a movable seat, a fixed seat, a clamping block driven by four telescopic cylinders, and an axial positioning block for the small master cylinder to be positioned and clamped. The movable seat is connected to the positioning block on the other side, and the fixed seat is connected to the positioning carrier plate on the same side. Driven by the push hydraulic cylinder, the movable seat and the fixed seat on the same side are offset and adjusted to achieve the release or pre-positioning of the small master cylinder to be positioned and clamped. Four telescopic cylinders are arranged on the side of the fixed seat facing the movable seat, and the telescopic rod of each telescopic cylinder is connected to a movable clamping block.

[0008] Furthermore, the movable clamping block is made of steel to ensure that the small master cylinder in rigid contact is accurately positioned and subjected to moderate force under the push of the telescopic cylinder, without damaging the outer wall surface of the small master cylinder.

[0009] Furthermore, an axial positioning block for supporting the upper end flange of the small master cylinder is arranged on the movable seat.

[0010] Furthermore, the movable clamping block cooperates with the fixed clamping block arranged on the corresponding movable seat to implement eight-point clamping on the outer wall of the cylindrical small master cylinder, and multiple groups of four-axis clamping assemblies synchronously position and clamp the small master cylinder of each workstation.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The multi-station small master cylinder hydraulic four-axis clamp utilizes a pushing hydraulic cylinder to synchronously and unidirectionally drive the multiple groups of four-axis clamping components on both sides of the positioning carrier to slide in an offset manner, so as to release or clamp the small master cylinders on multiple stations, making it convenient for workers to take and place the small master cylinders to be milled. After the multiple stations have been initially positioned, the four telescopic cylinders on each station implement four-point pushing, and cooperate with the fixed clamping blocks on the positioning movable seat to achieve the final clamping of the small master cylinder, thereby completing the positioning and clamping of the small master cylinders on all stations, which is practical and convenient.
