Description

Technical Field

[0001] The invention belongs to the field of mechanical processing tool design and manufacturing, in particular to a floating support device for mechanical processing. Background Art

[0002] When machining the engine deflector welding assembly, due to the 1.2mm wall thickness of the rib plate, the tool will be let down when machining the size of the middle part, and the part cannot be machined. It is necessary to set a support under the machined surface. Figure 1 As shown in the figure, the usual support structure cannot solve this type of technical problem. This is because the usual support structure uses the adjustable support GB2230-80 and the nut GB52-76 as the support structure, that is, 6 or 8 groups of evenly distributed supports are selected on the back of the surface to be machined. This support structure is only suitable for parts with larger inner holes ( Figure 1 The middle elliptical area A is the inner hole of the part). On the one hand, because the adjustment of the support requires the hand and the tool to pass through the inner hole to reach the bottom of the machined surface to operate and adjust the support GB2230-80 and the nut GB52-76, only when the inner hole is large enough will the operator have enough operating space to adjust the support height. On the other hand, Figure 1 The bottom surface of the support structure is placed on the machine tool workbench, and it is impossible to enter from the bottom surface of the support structure to adjust it. Therefore, the traditional support structure cannot adjust the support height for parts with small inner holes, because the operator cannot directly put his hands and tools through the small inner hole to adjust the support. Summary of the invention

[0003] In order to solve the above technical problems, the present invention aims to provide a floating support device for mechanical processing. When the device is used to mechanically process an engine deflector welding assembly with a small inner hole, the overall floating support is achieved by adjusting above the inner hole and the processed surface, thereby meeting the purpose of adjustable floating support for parts with small operating spaces.

[0004] The present invention adopts the following technical solutions:

[0005] A floating support device for machining, comprising:

[0006] A base, the base comprising a bottom surface at the lower end and a side wall arranged along the circumference of the bottom surface, a stopper for fitting and positioning the part to be processed is arranged at the upper end of the side wall, and a concave cavity is formed between the bottom surface and the side wall;

[0007] A supporting plate, the supporting plate is located in the cavity of the base, the supporting plate comprises a plate surface and a supporting surface, and the plate surface is provided with a first through hole and a second through hole;

[0008] A large and small head stud, wherein the large and small head stud is located in the cavity of the base, and the small head thread section of the large and small head stud is vertically connected to the bottom surface of the base, and the large head thread section of the large and small head stud passes through the second through hole and extends to the other side of the disk surface;

[0012] A stud, one end of which is threadedly connected to the bottom surface of the base, and the other end of which is threadedly connected to the threaded inner hole of the spherical nut.

[0013] Furthermore, the floating support device for machining also includes a combined pressure hook, which is connected to the base, and the pressure hook of the combined pressure hook is located above the stopper at the upper end of the side wall of the base.

[0014] Furthermore, the floating support device for machining also includes a locking screw, which is threadedly connected to the bottom surface of the base, and the locking screw intersects with the stud so that the stud cannot rotate relative to the base.

[0015] As an option, there are a plurality of second through holes, which are evenly distributed on a circle centered on the first through hole.

[0016] As an option, the support disk has support surfaces spaced and evenly distributed on its surface for fitting to the surface of the part to be processed.

[0019] As an option, the spherical nut further includes an inner hexagonal hole coaxial with the threaded hole thereof, and the inner hexagonal hole and the nut are both located on the same side of the supporting plate.

[0020] Compared with the prior art, the present invention achieves the purpose of adjustable support of small space parts by means of overall floating support. Specifically, the present invention has the following characteristics:

[0021] (1) In order to solve the problem of small inner holes of the parts to be processed, a spherical nut is set in the inner hole and the spherical nut is rotated separately to achieve the purpose of floating support adjustment, thereby extending the support adjustment position from below the parts to be processed and the inner hole to above the inner hole, without the need for operators to put their hands and tools into the inner hole;

[0022] (2) The spherical nut, the support plate, the large and small head studs, the spring and the nut form an integral support, which realizes the upward support of the part to be processed from the bottom of the part to be processed, and realizes the overall support through the support plate.

[0023] (3) A supporting surface is provided on the supporting plate, and a positioning stop is provided on the side wall of the base, and a combined pressing hook is used to realize the positioning and pressing of the parts to be processed. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, but it should not be understood that the scope of the subject matter described in the present invention is limited to the following embodiments. Without departing from the above-mentioned technical ideas of the present invention, various modifications, substitutions and changes made according to the common technical knowledge and customary means in the field are included in the scope of the present invention.

[0029] like Figure 2 As shown, the floating support device for machining is mainly composed of a base 1, a large and small head stud 2, a spring 3, a support plate 4, a nut 5, a spherical nut 8, a stud 9, a locking screw 10 and a combined pressure hook 11.

[0030] The base 1 is the base of the whole device, and the base 1 includes a bottom surface at the lower end, and a side wall arranged along the circumference of the bottom surface. The upper end of the side wall is provided with a stopper for fitting and positioning with the guide plate welding assembly 6 according to the outer diameter size of the guide plate welding assembly 6. The stopper plays a role of supporting and centering, and a concave cavity is formed between the bottom surface and the side wall.

[0031] 4 pieces in total (corresponding to Figure 3 The four second through holes evenly distributed on the circumference of the support are evenly distributed on the inner side of the floating support. The small end of the reducer stud 2 (the small head threaded section with a smaller outer diameter) is screwed into the base 1, and the step surface on the reducer stud 2 fits with the bottom surface of the base 1. The spring 3 is inserted into the large end (the large head threaded section with a larger outer diameter) of the reducer stud 2. The large end of the reducer stud 2 guides the spring 3. The large end of the reducer stud 2 is installed into the second through hole on the support disk 4 and extends to the other side of the support disk 4. The nut 5 is screwed into the large end of the reducer stud 2 on this side to prevent the support disk 4 from running out.

[0032] like Figure 3 The support disk 4 is a disk, and a plurality of steps (protrusions) are arranged on one end surface of the disk. Figure 3 The middle left figure shows 8 evenly spaced steps. The end faces of the steps serve as the support surfaces 7 that fit the guide plate welding assembly 6, which facilitates the adjustment of the local position and grinding. The middle position of the support plate 4 is processed with a first through hole, such as Figure 2 and Figure 3 As shown in the middle right figure, one end of the first through hole is processed with a 120° chamfer, and the plane where the chamfer is located is tangent to the spherical surface of the spherical nut 8. The gap between the first through hole and the spherical nut 8 is controlled at 1mm; the spherical nut 8 plays the role of adjusting locking and supporting, and the spherical surface ensures uniform force at the contact point;

[0033] like Figure 2 The combined pressing hooks 11 arranged on the circumferential side wall of the base 1 play the role of pressing the guide plate welding assembly 6.

[0034] like Figure 2 The middle hole of the spherical nut 8 is a threaded hole for connecting with the stud 9. The spherical nut 8 is also provided with an inner hexagonal hole coaxial with the threaded hole for easy adjustment.

[0035] like Figure 2 The locking principle of the locking screw 10 is to screw the stud 9 into the base 1, tap a threaded hole between the base 1 and the stud 9, and then screw in the locking screw 10, so that the stud 9 is fixed to the base 1, for example, the threaded hole is half on one side of the base 1 and the stud 9.

[0036] After the guide plate welding assembly 6 is assembled on the floating support device of the present invention, the inner hexagonal hole ( Figure 2 The position marked by the letter B in the middle drives the spherical nut 8 to rotate relative to the stud 9, thereby driving the support plate 4 to move up or down, and the spring 3 provides a uniform supporting force for the support plate 4, and the support plate 4 supports the guide plate welding assembly 6 as a whole from the bottom.
