Description

Technical Field

[0001] The utility model belongs to the technical field of composite material processing, and relates to a full-automatic rotary adsorption tooling for specimen processing, which is used for a numerical control processing method for automatically rotating and trimming a radome specimen. Background Art

[0002] The processing of radome specimens is generally composite parts or honeycomb parts in the furnace. After forming, the size is relatively large and needs to be cut into the required size by a machine tool. Affected by the conditions of a universal milling machine, the cutting steps are very cumbersome during cutting, and there are relatively large safety hazards. After discussion, it is decided to switch to cutting with a numerical control milling machine. Since the Z-axis of a three-axis numerical control milling machine cannot change the angle by itself, it can only cut with a fixed blade angle. After cutting two parallel sides, the workpiece needs to be manually rotated 90 degrees for the other two perpendicular sides, and then leveled and aligned again, which is very troublesome. Existing numerical control cutting (three-axis numerical control milling machine) and universal milling cutting use tape for pasting and cutting, and the operation difficulty is extremely high. Disassembling and rotating the workpiece is very cumbersome, time-consuming and laborious, and it is easy to collide with the blade during the disassembly and rotation process, causing injury to personnel, with extremely high risks, and it is also easy to damage the product. Summary of the Invention

[0003] The purpose of the utility model is to provide a full-automatic rotary adsorption tooling for specimen processing to solve the limitations existing in the existing cutting, such as cumbersome traditional cutting steps, uncontrollable quality, low safety index, high labor cost, and extremely low production efficiency.

[0004] In order to solve the above technical problems, the technical solution of the utility model is as follows:

[0005] A full-automatic rotary adsorption tooling for specimen processing, the tooling consists of a base below and a vacuum adsorption flat plate above. The base is fixed on a machine tool, and the vacuum adsorption flat plate is connected to the base in the middle through a rotating mechanism; the rotating mechanism drives the vacuum adsorption flat plate to rotate; the machine tool is a three-axis numerical control milling machine;

[0006] The base is provided with positioning pin holes and a rotation limit groove above. The positioning pin holes are used for fixing and positioning after the vacuum adsorption flat plate rotates, and the rotation limit groove is used to control the angle of the upper flat plate after rotation;

[0007] The bottom of the vacuum adsorption flat plate has positioning holes that cooperate with the positioning pin holes, and a second limit groove that cooperates with the rotation limit groove;

[0008] The internal air pipeline of the vacuum adsorption flat plate has adsorption holes communicated with the air pipeline on the upper end face, and the specimen is adsorbed and fixed on the adsorption holes; a vacuum ventilation hole is provided on the side of the vacuum adsorption flat plate for evacuating the air pipeline.

[0009] The number of the adsorption holes is the same as the number of the specimens finally obtained by cutting.

[0010] In the middle of the bottom of the vacuum adsorption plate, there is a central positioning hole for positioning with the center of the rotating mechanism.

[0011] Around the central positioning hole, there are quick insertion holes for cooperating and fixing with the quick insertion pins above the rotating mechanism.

[0012] The vacuum vent holes are used to connect to a vacuum air source.

[0013] The vacuum adsorption plate rotates 90° on the processing plane.

[0014] Inside the rotating mechanism, there is a cam, and the rotation of the cam is realized through pneumatic control.

[0015] Preferably, the rotation limiting groove and the second limiting groove are limited by cooperation with ball bearings.

[0016] In the tooling of the present utility model, the vacuum vent holes can be opened on one side surface, or can be opened on two opposite side surfaces of the vacuum adsorption plate.

[0017] The adsorption holes are communicated with the vacuum vent holes through the ventilation pipeline. When the vacuum vent holes are opened on one side surface, the whole ventilation path can be formed after communication; when the vacuum vent holes are opened on two opposite side surfaces of the vacuum adsorption plate, the adsorption holes are divided into two groups. After the inside of each group is communicated, it is communicated with the vacuum vent holes on the side surface, forming two independent ventilation paths. Install a 90-degree adjustable air cylinder in the bottom base of the tooling, and use compressed air as the power to realize the rotation of the tooling. The air inlet switch controls the air inlet direction, and the pressure reducing valve controls the air inlet force to achieve a buffering effect.

[0018] The beneficial effects of the present utility model:

[0019] The vacuum adsorption machine processing tooling of the present utility model is very convenient to disassemble and does not damage the product. Moreover, the tooling is an automatic rotating tooling, which saves manpower and time. Without human participation in the rotation of the workpiece, the risk of collision is avoided, and the production safety index is effectively improved. Install a 90-degree adjustable air cylinder in the bottom base of the tooling, and use compressed air as the power to realize the rotation of the tooling. The air inlet switch controls the air inlet direction, and the pressure reducing valve controls the air inlet force to achieve a buffering effect and achieve precise positioning.

The schematic diagram of the vacuum adsorption flat plate 2 is as Figure 2As shown. The base 1 is fixed on the machine tool 11 through a pressing plate 13. The vacuum adsorption flat plate 2 and the base 1 are connected in the middle through a rotating mechanism 3, as Figure 4 shown; the rotating mechanism 3 drives the vacuum adsorption flat plate 2 to rotate; after rotation, the positioning pin holes 4 are used to strengthen the fixation and prevent misalignment of the tooling; the rotation angle is prevented from misaligning through the rotation limit groove 5; as Figure 3 shown, the upper vacuum adsorption flat plate 2 can be quickly replaced with the lower base through the quick insertion hole 10; the workpiece is held by the vacuum vent holes 8 and the surrounding sealing grooves;

[0030] In a specific embodiment, the number of final products is 24. The vacuum adsorption flat plate 2 of the vacuum adsorption tooling is composed of 24 independent vacuum adsorption discs with a size of 46*46 mm. The distance between each disc surface is 6 mm, and a 3-mm relief groove is made in the middle to avoid air leakage after cutting, realizing independent adsorption of each product. After the transverse cutting is completed, the rotation switch is controlled by a program to manipulate the rotation of the vacuum adsorption flat plate. After rotation, a positioning pin is inserted for strengthening fixation and longitudinal cutting is carried out. After the longitudinal cutting is completed, the positioning pin is pulled out, and then the rotation switch is controlled by a program to manipulate the rotation of the vacuum adsorption flat plate 2 to end the processing. This tooling is also designed with: a 90-degree adjustable cylinder is installed in the base, powered by compressed air, to realize the rotation of the tooling. The intake switch controls the intake direction, and the pressure reducing valve controls the intake force to achieve a buffering effect and accurate positioning.

[0031] The use process of the full-automatic rotating adsorption tooling of the present utility model: Install the base on the machine tool workbench 11 → Clamp and align through the positioning holes 7 → Hold the base pressing plate 13 → Install the product by adsorption → Insert the positioning pin holes 4 → Cut and process the first side → Clean the dust (while pulling out the positioning pin) → The machine tool toggles the rotation switch → The rotating mechanism 3 rotates / the upper vacuum adsorption flat plate 2 rotates → Insert the positioning pin holes 4 → Process the second side → Clean the dust (while pulling out the positioning pin) → The machine tool toggles the rotation switch → The tooling rotates (returns to the original position).

[0032] As shown in Table 1 and Table 2 below, the process and time cost for processing 16 specimens at one time using the automatic rotating tooling are shown. It can be seen that for processing 1500 pieces of a certain specimen, conventional milling requires 512 hours. After the transformation, it takes 42 hours, saving a total of 470 hours, improving the product processing efficiency, shortening the production processing operation time, and greatly saving costs.
