Description

Technical Field

[0001] The utility model relates to the technical field of perpendicularity detection tooling, in particular to a perpendicularity detection tooling for parts. Background Technique

[0002] A perpendicularity detection tooling for parts is a precision device used to measure and ensure that parts reach the required perpendicularity during processing or assembly. This kind of tooling is usually used in the fields of machining, assembly and quality control.

[0003] In the prior art, a tooling for detecting the perpendicularity of parts disclosed in the patent with the publication number of CN210426390U mainly adjusts the height of the detection head through a Z-direction slide table, and drives the detection head to rotate by rotating a rotating plate around a core shaft. During the rotation process, the detection head reads the perpendicularity of the workpiece to be measured placed on the core shaft; when detecting the perpendicularity of the surface of an irregular and small-volume workpiece, during the rotation of the detection head and other operations, the position of the head needs to be continuously adjusted to detect each surface of the workpiece.

[0004] Through the technologies in related fields, for the perpendicularity detection tooling of parts, most of them need to fix instruments such as dial indicators on the tooling for detection, and professional staff are required to read the values. Moreover, precision measurement instruments are generally expensive, which is not suitable for factories and other places with large detection requirements, and the applicability is poor. Content of the Utility Model

[0005] The purpose of the utility model is to provide a perpendicularity detection tooling for parts to solve the above problems.

[0006] The utility model realizes the above purpose through the following technical solutions:

[0007] A perpendicularity detection tooling for parts includes a detection platform, a pasting unit for amplifying the detection result, and a height fixing unit;

[0008] Detection platform: A rod seat is adsorbed on the upper end. A magnetic disk is embedded inside the rod seat. A straight optical axis is installed at the upper end of the rod seat. An axial slide seat is slidably connected to the straight optical axis; when the lower end of the rod seat is horizontally in contact with the upper plane of the detection platform, the perpendicularity of the straight optical axis can be ensured. Relying on the magnetic force of the magnetic disk, it is adsorbed to the iron detection platform and can be randomly adjusted in position.

[0009] Component for attaching: It includes a cross column with one end connected to the shaft sliding seat. An internal end of the cross column is provided with a thin column groove, and a piston disk is slidably connected inside the thin column groove. The other internal end of the cross column is provided with a thick column groove, and the thick column groove communicates with the thin column groove. One end of a T-shaped ball seat is slidably connected inside the thick column groove, and a attaching ball is rotatably connected inside the other end of the T-shaped ball seat. The thick column groove is filled with an incompressible liquid, and an observation component is provided on the cross column. When detecting the perpendicularity of a part, the attaching ball is made to contact the part to be measured. At the same time, when the attaching ball is stressed, the T-shaped ball seat contracts into the thick column groove, applying force to the liquid in the thick column groove, causing the piston disk to be located in the middle. Then, the entire cross column is moved up and down, and the attaching ball always contacts the surface of the part to be measured. When there are depressions or protrusions on the vertical surface of the part, (according to the continuity equation in fluid mechanics, for an incompressible fluid, the flow rate is constant; if the fluid flows from a thick pipe to a thin pipe, due to the smaller cross-sectional area of the thin pipe, the same flow rate must pass through the thin pipe at a higher speed), the piston disk can be quickly moved, realizing the visualization of the perpendicularity detection of the part and magnifying the tiny offset amount.

[0010] Height fixing unit: It is installed at the front end of the shaft sliding seat. The height fixing unit can position the height of the shaft sliding seat.

[0011] Furthermore, the observation component includes an observation strip made of a transparent material, and a scale groove is provided inside the observation strip. When detecting the perpendicularity of a part, the position of the piston disk can be observed through the observation strip, and the perpendicularity at this position of the part detection can be recorded with reference to the scale in the scale groove.

[0012] Furthermore, the component for attaching also includes an elastic member with one end connected to one end of the T-shaped ball seat, and the other end of the elastic member is connected inside the thick column groove. An exhaust hole is provided on the lower side of the internal end of the cross column, and the exhaust hole communicates with the thin column groove. Using the elastic force of the elastic member, the T-shaped ball seat can always be in an extended state, and at the same time, it is also convenient to contact this position when there is a depression on the vertical surface of the part. When detecting the perpendicularity of a part, if the part is not perpendicular and the piston disk keeps sliding, the air at the position without liquid in the thin column groove can be discharged through the exhaust hole to prevent the influence of compressed air on the detection value.

[0013] Further, the height - fixing unit includes a strip seat. A strip shaft is arranged inside the strip seat. A pressing strip is movably connected to the strip shaft. Anti - slip cross - strips are equidistantly installed on one side of the lower end of the pressing strip close to the straight optical axis. A torsion member is sleeved on the strip shaft. One end of the torsion member is connected inside the strip seat, and the other end of the torsion member is connected to the pressing strip. When detecting the perpendicularity of a part, after placing the part, by pressing the upper end of the pressing strip, the anti - slip cross - strips can be moved away from the straight optical axis to slide the height of the cross - column. When height - fixing is required, release the upper end of the pressing strip, and using the torsion of the torsion member, the anti - slip cross - strips can be made to contact the straight optical axis to achieve the positioning of the height of the cross - column part.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, the ball always contacts the surface of the part to be measured. When there are depressions or protrusions on the vertical surface of the part, the piston disk can be quickly moved, realizing the visualization of the perpendicularity detection of the part, magnifying the tiny offset, facilitating better observation by the staff, being simple and convenient to operate, having low cost, and stronger applicability.

[0016] 2. In the present utility model, when height - fixing is required for detecting the perpendicularity of a part, release the upper end of the pressing strip, and using the torsion of the torsion member, the anti - slip cross - strips can be made to contact the straight optical axis to achieve the positioning of the height of the cross - column part, which is simple to operate and convenient to use.

[0028] Embodiment

[0029] As Figures 1 - 5 shown, a part perpendicularity detection tooling includes a detection platform 1, a sticker unit and a height setting unit for magnifying the detection result;

[0030] Detection platform 1: A rod base 2 is adsorbed on the upper end. A magnetic disk 19 is embedded inside the rod base 2. A straight optical axis 3 is installed at the upper end of the rod base 2. An axial sliding seat 4 is slidably connected to the straight optical axis 3; as Figure 1 and Figure 2 shown, when the lower end of the rod base 2 contacts the upper plane of the detection platform 1 horizontally, the perpendicularity of the straight optical axis 3 can be ensured. Relying on the magnetic force of the magnetic disk 19, it is adsorbed to the iron detection platform 1 and can be randomly adjusted in position, facilitating the detection of the parts to be detected for perpendicularity placed on the detection platform 1.

[0031] Component pasting unit: It includes a cross column 5 with one end connected to the axial sliding seat 4. A thin column groove 7 is opened at one end inside the cross column 5. A piston disk 11 is slidably connected inside the thin column groove 7. A thick column groove 6 is opened at the other end inside the cross column 5. The thick column groove 6 communicates with the thin column groove 7. One end of a T-shaped ball seat 8 is slidably connected inside the thick column groove 6. A pasting ball 9 is rotatably connected inside the other end of the T-shaped ball seat 8. An incompressible liquid is filled inside the thick column groove 6. An observation component is provided on the cross column 5; as Figure 3 and Figure 4 shown, when detecting the perpendicularity of a part, the pasting ball 9 is made to contact the surface of an irregular and small-volume workpiece. At the same time, when the pasting ball 9 is stressed, the T-shaped ball seat 8 contracts into the thick column groove 6, applying force to the liquid inside the thick column groove 6, making the piston disk 11 located in the middle. Then, the cross column 5 as a whole is moved up and down, and the pasting ball 9 always contacts the surface of the part to be measured. When the pasting ball 9 moves up and down, that is, rises and falls perpendicular to the horizontal plane, as Figure 5 shown, the pasting ball 9 can contact the protruding or sunken positions perpendicular to the horizontal plane of the workpiece, thereby detecting the deviation of the local perpendicularity of the workpiece. When there are depressions or protrusions on the vertical surface of the part, (According to the continuity equation in fluid mechanics, for an incompressible fluid, the flow rate is constant; if the fluid flows from a thick pipe to a thin pipe, due to the smaller cross-sectional area of the thin pipe, the same flow rate must pass through the thin pipe at a higher speed), the piston disk 11 can be made to move quickly, realizing the amplification and visualization of the detection result of the perpendicularity of the part, magnifying the tiny offset amount, facilitating better observation by the staff, being simple and convenient to operate, having a low cost, and being more applicable; when detecting the perpendicularity of other positions on the surface of an irregular and small-volume workpiece, the pasting ball 9 can be first made to contact any position on the surface of the workpiece, making the piston disk 11 located in the middle at this time. When vertically lifted, the perpendicularity deviation between other positions on the vertical line and this point can be detected, facilitating batch sampling detection of the perpendicularity of the workpiece surface and improving production efficiency.

[0032] Height fixing unit: It is installed at the front end of the axial sliding seat 4. As Figure 2 shown, the height fixing unit can position the height of the axial sliding seat 4, facilitating the detection and maintenance of a single position on the vertical plane of the part and facilitating the staff to record.

[0033] The observation component includes an observation bar 13, which is made of a transparent material. A scale groove 14 is formed inside the observation bar 13. As Figure 1 , Figure 3 and Figure 4 shown, when detecting the perpendicularity of a part, the position of the piston disc 11 can be observed through the observation bar 13. Referring to the scale in the scale groove 14, the perpendicularity of this position during part detection can be recorded. The detection of perpendicularity is more intuitive, simpler and more convenient.

[0034] The component for attaching parts also includes an elastic member 10 with one end connected to one end of the T-shaped ball seat 8. The other end of the elastic member 10 is connected to the inside of the thick column groove 6. An exhaust hole 12 is formed on the lower side of the inner end of the cross column 5, and the exhaust hole 12 communicates with the thin column groove 7. As Figure 3 shown, in the natural state, due to the elastic force of the elastic member 10, the T-shaped ball seat 8 can always be in the extended state. At the same time, when there is a depression on the vertical plane of the part, it is also convenient to contact this position to record the perpendicularity deviation; when detecting the perpendicularity of a part, if the part is not perpendicular and the piston disc 11 slides continuously, the air at the position without liquid in the thin column groove 7 can be discharged through the exhaust hole 12 to prevent the influence of compressed air on the detection value, and the perpendicularity of the part can be detected more accurately.

[0035] The height fixing unit includes a strip seat 15. A strip shaft is provided inside the strip seat 15. A pressure strip 16 is movably connected to the strip shaft. Anti-slip cross strips 18 are equidistantly installed on the lower side of the pressure strip 16 near one side of the straight optical axis 3. A torsion member 17 is sleeved on the strip shaft. One end of the torsion member 17 is connected to the inside of the strip seat 15, and the other end of the torsion member 17 is connected to the pressure strip 16. As Figure 1 and Figure 2 shown, when detecting the perpendicularity of a part, after placing the part, by pressing the upper end of the pressure strip 16, the anti-slip cross strips 18 can be moved away from the straight optical axis 3 to slide the height of the cross column 5. When height fixing is required, release the upper end of the pressure strip 16, and due to the torsion force of the torsion member 17, the anti-slip cross strips 18 can be made to contact the straight optical axis 3 to achieve the positioning of part of the height of the cross column 5. The operation is simple and convenient to use.

[0036] Working principle: When in use, as Figures 1 - 5 shown, when detecting the perpendicularity of a part, the part to be measured can be first placed on the detection platform 1. Then, relying on the magnetic force of the magnetic disk 19, the position of the straight optical axis 3 can be adjusted, and then the position of the ball attachment 9 can be adjusted so that the ball attachment 9 contacts the part to be measured. At the same time, when the ball attachment 9 is stressed, the T-shaped ball seat 8 contracts into the thick column groove 6, applying force to the liquid in the thick column groove 6 to make the piston disc 11 located in the middle position;

[0037] As Figures 1 - 4As shown, by pressing the upper end of the pressing strip 16, the anti-slip cross bar 18 is moved away from the height of the slidable cross column 5 on the straight optical axis 3. Using the elastic force of the elastic member 10, the T-shaped ball seat 8 can always be in the extended state, and the ball 9 always contacts the surface of the measured part. When the ball 9 moves up and down, that is, rises and falls perpendicular to the horizontal plane, as Figure 5 shown, the ball 9 can contact the convex or concave position perpendicular to the horizontal plane of the workpiece, and then the deviation of the local perpendicularity of the workpiece can be found. When there is a depression or protrusion on the vertical surface of the part, (according to the continuity equation in fluid mechanics, for an incompressible fluid, the flow rate is constant; if the fluid flows from a thick pipe to a thin pipe, due to the smaller cross-sectional area of the thin pipe, the same flow rate must pass through the thin pipe at a higher speed), the piston disk 11 can be quickly moved, realizing the visualization of the perpendicularity detection of the part, magnifying the tiny offset amount, and facilitating the staff to better observe the detection result. When detecting the perpendicularity of other positions on the surface of an irregular and small workpiece, the ball 9 can be first made to contact any position on the surface of the workpiece, so that the piston disk 11 is located in the middle at this time. When vertically ascending, the perpendicularity deviation between other positions on the vertical line and this point can be found, facilitating the batch sampling detection of the perpendicularity of the workpiece surface and improving the production efficiency;

[0038] As Figure 1 and Figure 2 shown, when it is necessary to set the height for detecting the perpendicularity of the part, loosen the upper end of the pressing strip 16, and using the torsion force of the torsion member 17, the anti-slip cross bar 18 can be made to contact the straight optical axis 3, realizing the positioning of part of the height of the cross column 5. The operation is simple and convenient to use.
