The invention relates to a balanced base for a gantry-type five-axis machine, comprising a base frame, a base plate, a balance spring machine, an upper frame, a telescopic column, a base, an exhaust fan, and a shock-absorbing bracket. The base plate is arranged on the base frame Above, the balance spring machine is set at the bottom of the base frame, the upper frame is set at the bottom of the balance spring machine, the telescopic column is set under the upper frame, the base is set under the telescopic column, and the base There are a plurality of exhaust fans and shock-absorbing brackets evenly distributed on the outside; the base of the present invention does not rely on external clamping, has anti-interference ability, does not introduce external interference, has high processing precision, and is equipped with a shock-absorbing mechanism to eliminate vibration during processing. The base of the present invention combines the anti-interference function and heat dissipation function with each other, without extra vibration, and has a good heat dissipation effect; the base of the present invention is equipped with a dust removal mechanism, which has a good dust removal effect and avoids dust accumulation from affecting the balance.

The invention provides a tinned copper core polyperfluoroethylene propylene insulated wire for aerospace and a manufacturing device, the wire includes a copper core, a first insulating layer, a shielding layer, a second insulating layer, a protective layer and a balance layer; The outer surface of the copper core is tin-plated; the first insulating layer is extruded on the copper core; the shielding layer is covered on the outer surface of the first insulating layer; the second insulating layer is extruded and formed outside the shielding layer. The first insulating layer and the second insulating layer are polyperfluoroethylene propylene; the protective layer is arranged on the outer surface of the second insulating layer. The manufacturing device includes a segment positioning module, an electronic weighing module, an operation module, an execution module and a 3D printing module; it is used for segmenting, positioning and segment quality measurement of the wire after the protective layer is set; according to the quality of each segment and the setting Calculate the segmental standard quality to obtain the material consumption of the positioning segmental balance layer; form a control instruction; use the 3D printing module to control the material consumption of the printing positioning segmental balance layer.

The invention discloses a manufacturing method for a cast aluminum type engine blocking cover. The manufacturing method for the cast aluminum type engine blocking cover includes the following steps that firstly, casting is performed, wherein the blocking cover is cast through a metal mold casting method, the bottom face of one side of the blocking cover is a plane, and the other side of the blocking cover is a to-be-machined assembly face; secondly, an end face is turned, wherein the blocking cover is clamped through a turning clamp, the assembly face of the blocking cover is turned, the turning clamp comprises a flange sleeve clamping plate used for ejecting the bottom face of the blocking cover, and a blocking cover top plate used for clamping the assembly face of the blocking cover, and certain machining allowance is reserved for the assembly face of a blank of the blocking cover; and thirdly, hole drilling is performed, wherein the assembly face, machined in the second step, of the blocking cover is placed in a blocking cover installing and clamping device in a whole face attaching manner, the angle and the pressing force of the blocking cover are adjusted by adjusting an angular direction adjusting device and a tight holding force adjusting device, and hole drilling is performed. The invention provides the manufacturing method avoiding sunken deformation of the blocking cover in the end face turning work procedure and thus guaranteeing the planeness of the end face of the blocking cover.
