Description

Technical Field

[0001] The invention relates to a tool fixture, in particular to a guide tool for high temperature resistant castings. Background Art

[0002] Due to the high temperature, soft surface texture, easy scratches, sand core falling and other factors of high temperature aluminum alloy castings, ordinary tooling and fixtures cannot achieve accurate positioning, or the positioning products are achieved but the scratches are serious and normal production cannot continue. The present invention relates to a guide fixture for high temperature resistant castings, which has a simple structure and is easy to operate, overcomes the above problems, and smoothly realizes the coding processing and positioning of aluminum alloy castings under high temperature conditions. Summary of the invention

[0003] The purpose of the present invention is to solve the deficiencies of the above-mentioned technology and to provide a guide fixture for high-temperature resistant castings which is resistant to high temperatures and will not be damaged by bumps and collisions and can achieve precise positioning of high-temperature castings.

[0004] The objective of the present invention is achieved through the following technical scheme: a guide tool for high temperature resistant castings comprises a tool frame, a height support screw is installed at the middle position of the tool frame, a screw adjustment block is installed at the top of the height support screw, front and rear limit blocks are installed at the four peripheral positions of the tool frame, left and right limit blocks are installed on both sides of the tool frame, limit rods are installed on the front and rear limit blocks and the left and right limit blocks through limit bolts, a bearing spindle is installed in the limit rod, and a bearing is installed on the top of the bearing spindle.

[0005] The limiting rod is inclined inward at an acute angle. The tooling frame is provided with a photoelectric induction switch through a telescopic rod to sense whether the installation of the high-temperature casting is in place.

[0006] After adopting the present invention, the high-temperature casting is placed and docked in all directions of front and back, left and right through the front and rear limit blocks, left and right limit blocks and the limit rods thereon, the main shaft of the bearing, and the bearing. The bottom of the high-temperature casting is longitudinally supported and positioned by the adjustment of the screw adjustment block on the height support screw, and the photoelectric sensor switch senses the in-place and positioning state of the high-temperature casting. Thus, the multi-directional guidance and precise positioning of the casting under high temperature are achieved, so that the high-temperature casting is free of bumps and scratches, and the quality of the casting is guaranteed; the distance adjustment and angle docking of the limit bolts can adjust the docking gap and angle between the bearing and the casting according to the actual thermal expansion and contraction size and draft angle of the high-temperature casting, effectively solving the problem of the difficulty of precise positioning of the high-temperature casting.

[0010] See attached Figure 1 , Figure 2 It can be seen that the guide tooling of the high-temperature resistant casting of the present invention includes a tooling frame 1, a height support screw 306 is installed in the middle position of the tooling frame 1 (a total of four pieces in the middle position, used to support the bottom of the high-temperature casting for height longitudinal positioning), a screw adjustment block 305 (which can adjust the longitudinal lifting) is installed on the top of the height support screw 306, front and rear limit blocks 2 are installed at the four peripheral positions of the tooling frame 1 (one piece on each of the four peripheral positions, used to locate the front and rear positions of the high-temperature casting), left and right limit blocks 3 are installed on both sides of the tooling frame 1 (one piece on each of the two side edges, which can be located at the outermost side and used to locate the left and right lateral positions of the high-temperature casting), and the front and rear limit blocks 2 and the left and right limit blocks 3 are all equipped with limit rods 304 through limit bolts 301, a bearing spindle 303 is installed in the limit rod 304, and a bearing 302 (resistant to high temperature and capable of rolling and rotating) is installed on the top of the bearing spindle 303. When the distance between the front and rear limit blocks 2 and the left and right limit blocks 3 is ≥250 mm, two limit blocks should be arranged.

[0011] The limit rod 304 is inclined inward at an acute angle (the angle and distance between the limit rod and the high-temperature casting can be properly adjusted by the tightness of the limit bolt 301). The tooling frame 1 is equipped with a photoelectric sensor switch 6 (one on the left and right sides, respectively, of the reflective type and the receiving type) through the telescopic rod 5 to sense whether the installation of the high-temperature casting is in place.

[0012] The present invention places the high temperature casting 4 (rolling contact with the bearing 302) in all directions of front and back and left and right respectively through the limiting rod 304, the bearing spindle 303 and the bearing 302, and the bottom of the high temperature casting 4 is longitudinally supported and positioned by the adjustment of the screw adjustment block 305 on the height support screw 306, and the photoelectric sensor switch 6 senses the in-place and positioning state of the high temperature casting 4. The height support screw 306 and the tooling frame 1 are an integrated structure (welded as a whole), and the height of the screw adjustment block 305 can be independently adjusted to ensure the longitudinal position of the high temperature casting.
