Detailed Description

The invention is further described by the following structural drawings and examples.

The first embodiment.

As shown in fig. 1-2.

A synchronous lifting table of taper hole cooperation fast-assembling connecting leg formula, includes desktop 1, base 2 and liftable table leg 3, liftable table leg 3 upper end and lower extreme all be equipped with toper insertion structure 4, be equipped with the toper plug-in mounting hole 5 that matches in the shape in the corresponding position department of desktop 1 and/or base 2, as shown in figure 1, the structure after the assembly is shown in figure 2.

The upper end of the liftable table leg 3 is provided with a conical insertion structure 4, the corresponding position of the table top 1 is provided with a conical insertion hole 5 matched in shape, the conical hole is matched with the starting Morse taper, the international standard of the taper in machining is provided, and the lifting table leg is mainly used for precision fixation of a rotary body in machinery and the origin of the Morse taper: was invented by the american mechanic for the 19 th century (Stephen a. Morse) to solve the gripping problem of twist drills.

Most of the small-taper-degree morse tool holders are connected by the taper, for example, the tool holder of a slotting tool holder machining center comprises a plurality of clamps, the connection of the clamps and a machine tool is taper, and the disassembly is convenient and good in universality.

The Morse taper rod is matched with the inner hole with taper, and utilizes friction force to transmit torque. Because the disassembly is simple and convenient, the repeated disassembly does not influence the precision, and the application in mechanical processing is very wide.

The taper hole is matched under the action of axial force F (shaft), so that self-locking can be ensured, and torque can be transmitted. The assembly and disassembly are easy, the fit press-in distance of the taper hole is short, the interference magnitude is the same, the fit length is the same, and compared with the cylindrical hole, the stroke of the interference fit part of the taper hole is small. The installation is very easy, again easy dismantlement. The damage to the surface is small; the centering is automatic, and centering nature is good, and taper hole cooperation is difficult to produce the skew like the cylinder is empty in the in-process of impressing, leads to unable installation. The assembly requirement is low; can be repeatedly used. The interference fit is damaged, and the standard interference fit can be formed only by using the same press-in force; the taper hole is convenient to use, the processing is not difficult, the processing precision is not problematic, and the contact area is only enough.

The taper is recommended and is typically 1: 10. To achieve the purpose of convenient installation and production

In the assembly of the table legs, the upper and lower parts can be assembled in a taper hole matching mode, and different combination assembly modes of upper part threads, pull rivet assembly and lower part taper hole matching assembly or lower part threads, pull rivet assembly and upper part taper hole matching assembly can also be adopted.

Meanwhile, when the taper hole is matched with an automatic assembly line, particularly an automatic assembly line for unmanned production, the centering is automatic, the centering performance is good, the positioning and the control of workers and machines are simple and easy, the design, the manufacture and the installation of the tool clamp are simple and convenient, the production flow is greatly accelerated, and the manufacturing cost is greatly reduced.

Example two.

As shown in fig. 3-4.

The utility model provides a synchronous lift table of foot formula is connected in taper hole cooperation fast-assembling, includes desktop 1, base 2 and liftable table leg 3, and the lower extreme of liftable table leg 3 is equipped with toper insertion structure 4, is equipped with toper plug-in hole 5 that matches in the shape in the corresponding position department of base 2, and the upper end of liftable table leg 3 is passed through the screw thread and is riveted structure 6 with drawing and link to each other with desktop 1, as shown in figure 3, the structure after the assembly is shown in figure 4. The screw thread has clearance so if need guarantee the concentricity the must increase a section smooth excircle, cooperation then the screw thread closes so can eliminate the clearance again, and processing requires highly, and the installation is inconvenient swift.

Example three.

As shown in fig. 5-6.

The utility model provides a synchronous lift table of foot formula is connected in taper hole cooperation fast-assembling, includes desktop 1, base 2 and liftable table leg 3, and the upper end of liftable table leg 3 is equipped with toper insertion structure 4, is equipped with toper plug-in hole 5 that matches in the shape in the corresponding position department of desktop 1, and the lower extreme of liftable table leg 3 passes through the screw thread and draws and rivet structure 6 and link to each other with base 2, as shown in figure 5, and the assembly structure is shown in figure 6. The screw thread has clearance so if need guarantee the concentricity the must increase a section smooth excircle, cooperation then the screw thread closes so can eliminate the clearance again, and processing requires highly, and the installation is inconvenient swift.

The utility model discloses the part that does not relate to is the same with prior art or can adopt prior art to realize.
