Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamp for machining a reference surface of a hydraulic valve block. Background Art

[0002] The hydraulic valve block is a block that controls the operation of the hydraulic oil. The valve block is used in the electro-hydraulic servo control system. In the TRT device, it is a subsystem that is one of the eight systems. During the processing of the hydraulic valve block, it is necessary to drill holes on multiple surfaces of the hydraulic valve block. During the drilling process, the valve block needs to be clamped and fixed. Although the current clamp can fix the valve block very well, after the valve block is fixed and the drilling process on one side of the valve block is completed, the valve block needs to be loosened, lifted up and turned over, and then clamped and fixed before the next side of the valve block can be processed. Since the valve block is heavy, it is more laborious to lift and turn it over. Utility Model Content

[0003] The utility model provides a clamp for machining a reference surface of a hydraulic valve block, which saves more effort without lifting the hydraulic valve block and turning over the surface.

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

[0005] A fixture for processing a reference surface of a hydraulic valve block comprises a base plate, a mounting groove is formed on the top outer wall of the base plate, a double-slide linear motor is mounted on the inner wall of the mounting groove, vertical plates are fixed on the two sliding members of the double-slide linear motor, a first rotating rod and a second rotating rod are respectively connected to the outer walls of opposite sides of the two vertical plates through bearings, a clamp is fixed to the opposite ends of the first rotating rod and the second rotating rod, one end of the outer wall of the first rotating rod is provided with equidistantly distributed sockets, an electric push rod is mounted on the top outer wall of the base plate, a supporting plate is fixed on the top of the piston rod of the electric push rod, a slide groove is formed on the outer wall of one side of the vertical plates, and a limiting component is mounted on the inner wall of the slide groove.

[0006] Through the above scheme, the hydraulic valve block can be placed on the supporting plate, and the two vertical plates are driven to approach each other by the double-slide linear motor, and then the two clamping plates are driven to approach each other to clamp the hydraulic valve block. After clamping, the top surface of the hydraulic valve block can be drilled. After the drilling of the top surface of the hydraulic valve block is completed, the supporting plate can be driven down by the electric push rod. At this time, the top of the limit component can be pulled out of the socket, and the first rotating rod can be rotated. At this time, the hydraulic valve block can be directly rotated to turn it over so that the next processed surface faces upward, and there is no need to lift the hydraulic valve block to turn it over, which is more labor-saving. After the surface is changed, the supporting plate can be pushed to reset by the electric push rod to continue to support the bottom of the hydraulic valve block. When the top of the limit component is inserted into the socket, the first rotating rod is limited to prevent it from rotating.

[0007] Preferably, the limiting assembly includes a sliding rod, a spring sleeved on the sliding rod, a slider sleeved on the sliding rod, and an insertion rod fixed on an outer wall of one side of the slider.

[0008] Through the above scheme, when the first rotating rod needs to be rotated, the insertion rod can be pulled downward by hand to pull the insertion rod out of the insertion hole. At this time, the first rotating rod can be rotated, and the sliding block will be driven to move downward to squeeze the spring during the downward movement of the insertion rod. When the first rotating rod needs to be limited, the insertion rod can be loosened, and the spring resets to drive the insertion rod to rise and be inserted into the insertion hole.

[0009] Preferably, an anti-skid pad is bonded to the outer wall of the bottom of the base plate, and an anti-skid thread is provided at the bottom of the anti-skid pad.

[0010] Through the above solution, the device is placed on the table more stably.

[0011] Preferably, the insertion rod is matched with the insertion hole.

[0012] Through the above solution, the insertion rod can be inserted into the insertion hole.

[0013] Preferably, the slider is slidably connected to the inner wall of the slide groove, a through hole is opened on the outer wall at the top of the slider, and the slider is sleeved on the sliding rod.

[0014] Through the above solution, the sliding block can be sleeved on the sliding rod.

[0015] Preferably, the double-slide linear motor and the electric push rod are both connected to a control switch via a wire, and the control switch is connected to an external power supply via a power line.

[0016] Through the above solution, the double-slide linear motor and the electric push rod can be powered on and operated.

[0017] The beneficial effects of the utility model are:

[0018] The hydraulic valve block can be placed on a supporting plate, and the double-slide linear motor can drive the two clamping plates to approach each other to clamp the hydraulic valve block. When the hydraulic valve block needs to be turned over, the supporting plate can be driven down by the electric push rod, and then the top of the limit assembly can be pulled out from the socket. At this time, the hydraulic valve block can be directly rotated to turn it over, and there is no need to lift the hydraulic valve block to turn it over, which is more labor-saving. After the change of surface, the supporting plate can be pushed back to its original position by the electric push rod, and then the top of the limit assembly can be inserted into the socket.
