Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and particularly relates to a device for auxiliary processing the flatness of a guide rail of a long-bodied slot-shaped part. Background Art

[0002] The guide rails of grooved parts are commonly seen in parts that perform linear parallel reciprocating motion. The grooves can accommodate some moving devices and play a protective role. The current processing method for the guide rails of grooved parts is: draw the upper and lower planes and the opening line of the guide rails according to the drawing, use different numbers of equal-height pads and bolts to evenly support the bottom of the grooved parts, and use a dial indicator to align the drawn lines. The problem with the current processing method is that the grooved parts are up to 1800mm long, and when the bottom is supported by pads and bolts, it is necessary to use dial indicators, leveling, and alignment many times, which is time-consuming and laborious.

[0003] like Figure 1 As shown in the figure, the structural characteristics of the part are as follows: the part is a typical long-bodied slot structure, with a U-shaped cross section, and L-shaped guide rails parallel to each other on both sides, with a length of about 1800mm, a guide rail flatness of 0.1mm, a parallelism of 0.05mm on the two opening sides, a relative center symmetry of 0.1mm, and a relative perpendicularity of 0.1mm on the guide rail plane. The part has poor rigidity, and during the processing, it is difficult to clamp, position and align, and has large deformation. It is difficult to ensure the technical indicators of the finished parts. In order to meet the product design requirements, the process design considers installing the part on a boring and milling fixture, and plans to use a CNC gantry boring and milling machine for processing. The upper and lower planes and the opening surface of the guide rail are processed with the part ear shaft as the positioning reference to ensure the product flatness and form and position tolerance requirements. Therefore, it is necessary to design a long-bodied slot part guide rail flatness auxiliary processing device. Utility Model Content

[0004] The technical problem to be solved by the utility model is: how to quickly and accurately realize the clamping and positioning problem during the processing of the guide rail of a long-bodied groove-shaped part.

[0028] The main body 1 is a flat plate structure, used to support positioning and clamp parts. Two T-shaped support plates are symmetrically distributed on one side of the plate. There are two V-shaped blocks 2 on the support plates to support the part trunnions. There are two threaded holes on the T-shaped support plates, which are used to install high feet and studs respectively, and their function is to level the height of the trunnions.

[0029] like Figure 5-Figure 7 As shown, there are 4 supporting plates at symmetrical positions on both sides of the middle of the body. There are 3 threaded holes on the plates, which are used to install the high legs 3, studs 5 and bolts of the supporting parts pads. The 4 supporting plates are used to make the parts evenly stressed. The high legs and studs are used to facilitate the leveling of the parts. The supporting pads are used to protect the surface of the parts and increase the wear resistance of the device. There are 2 triangular ribs on both sides of the 4 supporting plates, which are used to increase the strength of the supporting plates.

[0030] There is an L-shaped support vertical plate at the tail of the main body, and the horizontal direction of the part is adjusted by connecting the high support foot 3, the double-headed stud and the support on the plate to keep the height consistent.

[0039] 2. Place the parts on this device.

[0040] 3. Place the ear shaft of the part in the two grooves of the V-shaped block, use the high support foot 3 and the stud 5 to screw into the corresponding threaded holes of the T-shaped vertical plate, press the outer circle of the ear shaft with the pressure plate 4, and tighten it with the nut 6.

[0041] 4. Place the middle part of the part on two pads 7 and lock it with support nails 8 and nuts 6. Use high support feet 3 and studs 5 to screw into the corresponding threaded holes of the support vertical plate, press them with pressure plates 4 and tighten them with nuts.

[0042] 5. Place the tail of the part on the support nail 8 at the tail of the device and lock it with the nut 6. Use the high support foot 3 and the stud 5 to screw into the corresponding threaded hole of the support vertical plate, and press it with the pressure plate 4 and tighten it with the nut 6.
