Technical Field

The invention relates to the technical field of bearing machining, in particular to a floating support applied to a grinding machine.

Background

The positioning mode adopted by the grinding machine when grinding the outer circle of the part to be processed is shown in fig. 6 and 8. Specifically, the end face of the part 4 to be processed is pressed close to the magnetic pole 5 of the grinding machine through the attraction force of the magnetic pole 5, so that the axial fixation of the part 4 to be processed is realized, the radial fixation of the part 4 to be processed is realized by arranging two fixed supports 6 on the outer side of the part to be processed, and the excircle of the part 4 to be processed is ground through a grinding wheel after the axial fixation and the radial fixation are realized.

As shown in fig. 6 and 7, the conventional supports are fixed supports 6 of a straight rod type, the support blocks on the supports are fixed on the support rods by welding, and the support blocks are arranged obliquely relative to the support rods. When the device is installed, the supporting blocks of the two supports abut against the part 4 to be machined, and the supporting blocks and the excircle of the part to be machined are ensured to be in a tangent position relation. This requires adjustment of the support bevel angle to ensure a tangential positional relationship. Since the support is fixed, when the device is adjusted, the support needs to be adjusted continuously until the support is adjusted to a proper angle, and in the process, the optimal angle can not be found because one angle may need to be adjusted for a long time, and the skill requirement of an operator is very high.

In addition, the supporting head of the traditional support is made of hard alloy, the hard alloy can be worn after being used for a period of time, the process requirements cannot be met during product processing, and the hard alloy needs to be replaced because the surface roughness cannot meet the requirements after the hard alloy is worn and the product can be scratched during product processing, so that the product is unqualified. And the traditional support has the problem that the support head is welded, so that the replacement is labor-consuming and time-consuming.

Disclosure of Invention

Aiming at the problems, the invention provides the floating support applied to the grinding machine, the floating support can automatically find the machining center of the part, the efficiency of adjusting the equipment is greatly improved, the adjusting time of the equipment is shortened, and the rounding effect is good.

The technical scheme adopted by the invention for solving the technical problems is as follows:

a floating bearing applied to a grinding machine comprises a first supporting component and a second supporting component, wherein the first supporting component is positioned below a part to be machined, the second supporting component is positioned on the left side or the right side of the part to be machined, and the first supporting component and the second supporting component have the same structure;

the second supporting component comprises a supporting rod and a supporting head arranged at the inner end of the supporting rod, and the middle part of the supporting head is hinged with the inner end of the supporting rod;

the inner side surface of the supporting head is symmetrically provided with supporting inclined surfaces about the central line of the supporting rod, and the two supporting inclined surfaces form a concave structure together;

the supporting inclined plane is fixedly provided with a supporting block.

Furthermore, a clamping groove with a trapezoidal cross section is formed in the supporting inclined surface, and the supporting block is arranged in the clamping groove and clamped and fixed through a first locking bolt.

Furthermore, a first expansion joint is arranged on the bottom surface of the clamping groove, the supporting head is divided into a supporting head body and a clamping part by the first expansion joint, and a first locking bolt for clamping the supporting block is arranged between the clamping part and the supporting head body.

Furthermore, a first expansion joint is arranged on the bottom surface of the clamping groove, the first expansion joint penetrates through the supporting head along the direction perpendicular to the bottom surface of the clamping groove, and two first locking bolts are arranged between the clamping part and the supporting head body.

Furthermore, a groove used for containing the supporting head is formed in the inner end face of the supporting rod, the width of the groove is larger than that of the supporting head, a second expansion joint is arranged on the bottom face of the groove, and a second locking bolt used for adjusting the width of the second expansion joint is arranged on the supporting rod.

Furthermore, a rigidity reduction seam is arranged on the outer side of the adjusting hole on the front side face or the rear side face of the supporting rod.

Further, the distance from the center line of the rigidity reduction seam to the inner end of the support rod is equal to the distance from the blind end of the second expansion joint to the inner end of the support rod.

Furthermore, the supporting block is made of ceramic materials or metal ceramics.

Furthermore, a tension spring is arranged between the supporting rod of the second supporting component and the upper end part of the supporting head, and in a free state, the supporting head of the second supporting component is in a lifting state.

The invention has the beneficial effects that:

1. the floating support can automatically find the machining center of a part, greatly improves the efficiency of equipment adjustment, shortens the adjustment time of the equipment, and has a good rounding effect.

2. The supporting block is replaced by a ceramic block from the original hard alloy, so that the wear resistance is better, the friction trace on the product can be effectively eliminated, and the processing precision of the product is improved.

3. When the supporting block is designed to be placed, in order to prevent the ceramic block from slipping, the placed groove is designed to be a trapezoidal groove, and meanwhile, a clamping structure is designed. Through the design, the product quality is improved, the supporting block is convenient to replace, and the product quality and the production efficiency are improved.

4. The adjusting mechanism capable of adjusting the clamping tightness is arranged at the joint between the supporting head and the supporting rod, so that on one hand, after the gap is generated due to abrasion, the supporting head generates axial movement, and on the other hand, the adjusting mechanism can also adapt to supporting heads of different specifications and models within a certain range.

5. The tension spring is arranged on the second supporting component on the left side or the right side of the part to be processed, so that the supporting head of the second supporting component is in a lifted state in a free state, and the part can be conveniently loaded.

6. The traditional supporting mode is only provided with two supporting points, the part to be processed (especially the part to be processed with a thin wall thickness) is easy to deform during processing, the supporting points are four, and the part to be processed is not easy to deform.
