Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oil cylinder processing, in particular to a processing and clamping tool for oil inlet and outlet ports of an oil cylinder oil port block. Background Art
[0002] The port block is a component used to machine the oil inlet and outlet ports in a hydraulic cylinder. The current process for machining the port block (i.e., drilling the inlet and outlet ports) is as follows: first, clamp the port block in a bench vise. Using a machining center or other equipment, mill the top surface of the block flat and drill the inlet. Then, release the vise, flip the port block so the side faces upward, and clamp the block in a bench vise again. Using a machining center or other equipment, mill the side surface flat and drill the outlet.
[0003] The oil port block is processed by using a machining center and other equipment in conjunction with a bench vise, but this method has the following disadvantages: (1) the oil port block needs to be clamped twice, which is cumbersome and requires many steps; (2) the bench vise needs to be manually operated, which is time-consuming, labor-intensive, and inefficient; (3) the two clamping operations will cause the position of the oil port block to shift, resulting in the oil inlet and outlet being non-concentric at their intersection, and easily generating burrs and flash, which affects the quality. Utility Model Content
[0004] The utility model is to solve the above-mentioned problems existing in the prior art and provides a tool for processing the inlet and outlet of the oil cylinder oil port block, which has a simple structure, is easy to use, ensures the concentricity of the oil inlet and the oil outlet, avoids the problem of burrs and flash between the holes, and improves the processing efficiency.
[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: the present invention is a kind of oil inlet and outlet oil port processing and clamping tooling of the oil cylinder oil port block, including a longitudinal mounting plate and a transverse mounting plate, the transverse mounting plate is transversely fixed on the side of the longitudinal mounting plate, and an OK clamp is provided on the transverse mounting plate, and a left positioning plate and a right positioning plate are provided on both sides of the OK clamp, the space between the left positioning plate and the OK clamp forms a left positioning clamping position, and the space between the right positioning plate and the OK clamp forms a right positioning clamping position. The oil port block is placed in the left positioning clamping position and the right positioning clamping position, and the oil port block is clamped on the left and right sides by the OK clamp, so that the utility model can process two oil port blocks at the same time, which is beneficial to improving processing efficiency; the OK clamp is a prior art and can be purchased directly on the market, so it is not described in detail; the longitudinal mounting plate in the utility model is connected to the rotating shaft of the machine tool and can rotate with the shaft, so that the oil port block does not need to be disassembled and reversed, so there is no need to disassemble and assemble the oil port block (avoiding secondary clamping), thereby ensuring the concentricity of the oil port block in and out of the oil hole, and avoiding the problem of burrs and flash between the holes.
[0006] Preferably, the OK clamp is a pneumatic OK clamp, which is a prior art and is also known as a bidirectional pneumatic expansion clamp.
[0007] Preferably, a rear locating plate is provided on the transverse mounting plate. The space between the left locating plate, the OK fixture, and the rear locating plate forms a left locating clamping position, while the space between the right locating plate, the OK fixture, and the rear locating plate forms a right locating clamping position. The left and right locating clamping positions enable rapid positioning of the oil port block, ensuring machining accuracy.
[0008] Preferably, the left, right, and rear locating plates are each provided with at least two locating holes, and the transverse mounting plate is provided with locating pins that match the locating holes. The cooperation between the locating holes and the locating pins ensures the accuracy of the installation position of the left, right, and rear locating plates, thereby ensuring the positioning accuracy of the oil port block.
[0009] Preferably, the left positioning plate, the right positioning plate and the rear positioning plate are fastened to the transverse mounting plate by connecting bolts, so that the connection by the connecting bolts facilitates assembly and disassembly.
[0010] Preferably, a reinforcement plate is provided between the transverse mounting plate and the longitudinal mounting plate.
[0011] Therefore, the utility model has the following beneficial effects: through the cooperation between the OK clamp, the left positioning plate and the right positioning plate, the oil port block can be quickly clamped, and there is no need to disassemble the oil port block (avoiding secondary clamping), thereby ensuring the concentricity of the oil inlet and outlet holes of the oil port block, and avoiding the problem of burrs and flash between the holes.
