Technical Field

[0001] This utility model relates to the technical field of bearing component production equipment, and more specifically, to a special tooling for grinding the small end face of tapered rollers. Background Technology

[0002] Tapered rollers are an important component of tapered roller bearings. Tapered rollers are characterized by a tapered flank, a small end face, and a large end face. The small end face is flat and is typically ground using a surface grinder. However, due to the tapered flank, clamping the roller presents challenges compared to other types of rollers. Existing grinding machines can only hold one tapered roller workpiece at a time, resulting in significant time wasted on workpiece assembly and disassembly, leading to low production efficiency. Therefore, the production workshop considered designing a dedicated tooling for grinding the small end face of tapered rollers to improve production efficiency, hence this project. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-3The fixture shown is a special tooling for grinding the small end face of a tapered roller, including a first tooling component 1, a second tooling component 2, and a splicing element 3. The first tooling component 1 includes a strip-shaped seat 11, on which side strips 13 are welded to both sides in the width direction. The two side strips 13 are symmetrically arranged and are flush with the bottom surface of the strip-shaped seat 11. Several bolt holes 131 are provided on the side strips 13, and bolts are inserted through the side strips 13 to fix the strip-shaped seat 11 (i.e., the first tooling component 1) to the worktable of the grinding machine. To enhance the strength of the side strips 13, triangular ribs are welded to the outer wall of the strip-shaped seat 11. Plate 14, with the bottom of the triangular rib plate 14 connected to the side strip plate 13. The second tooling 2 includes a base 21, a first clamping block 22, and a second clamping block 23. The base 21 is also elongated. The first clamping block 22 is movably connected to the base 21, and the second clamping block 23 is fixedly connected to the base 21. The second clamping block 23 and the base 21 are fixedly connected by bolts. A positioning protrusion 212 is connected to the platform on the base 21 where the second clamping block 23 is installed. The second clamping block 23 is first fitted and inserted into the positioning protrusion 212, and then the bolts are tightened. In this way, the installation position of the second clamping block 23 on the base 21 is accurately determined. A plurality of workpiece cavities 24 are formed between the first clamping block 22 and the second clamping block 23. A tapered roller workpiece is loaded into each workpiece cavity 24. By pushing the first clamping block 22 toward the second clamping block 23, the tapered roller workpiece in the workpiece cavity 24 is clamped and fixed. Then, the first clamping block 22 and the second clamping block 23 are fixedly connected by a locking element 25 to clamp all the internal tapered roller workpieces. Under the above design, each second tooling 2 simultaneously clamps and loads multiple tapered roller workpieces, and the small end face grinding of multiple tapered roller workpieces can be completed simultaneously each time the grinding machine is started. The operation (the tapered roller workpiece is installed with the small end face facing upwards to adapt to the grinding operation requirements) significantly improves the grinding efficiency. In this utility model, the first tooling 1 is directly fixed to the worktable of the grinding machine. The second tooling 2 and the first tooling 1 are detachably connected (the second tooling 2 has a modular design and can be disassembled and replaced on the first tooling 1). The base 21 of the second tooling 2 is fitted into the strip seat 11 of the first tooling 1. Then, the base 21 and the strip seat 11 are fixedly connected by the splicing element 3 to realize the combined installation of the first tooling 1 and the second tooling 2. Figure 2 and Figure 3 As shown, the strip seat 11 has a positioning countersunk hole 12, the top of which is open. A positioning block 211 is fixedly connected to the bottom of the base 21. The size of the positioning block 211 is adapted to the positioning countersunk hole 12. The base 21 is inserted into the strip seat 11 from top to bottom through the fitting of the positioning block 211. After the two are inserted, the strip seat 11 forms a circumferential positioning restriction effect on the second tooling 2, such as... Figure 2As shown, the assembly element 3 includes a second stud 31 and a second butterfly nut 32. The second stud 31 is vertically and fixedly installed in the center of the positioning countersunk hole 12. The base 21 and the positioning insert 211 themselves have corresponding through holes. When the base is installed, the second stud 31 is installed through the base 21 and the positioning insert 211. The second butterfly nut 32 is threaded to the second stud 31. By turning the second butterfly nut 32 downward, the base 21 is pressed downward. Combined with the circumferential positioning and limiting effect of the strip seat 11 on the second tooling 2, the second tooling 2 is reliably fixed on the first tooling 1. When using this utility model, the second tooling 2 is first fully assembled, the tapered roller is loaded, and then the second tooling is assembled. When the second tooling 2 is assembled onto the first tooling 1, there is only one first tooling 1, which is directly fixed to the worktable of the grinding machine. There are two or more second tooling 2. While the previous second tooling 2 is carrying the tapered roller for grinding, the worker can assemble and load the tapered roller workpiece onto the next second tooling 2. This makes full use of the grinding time. After the previous second tooling 2 has finished grinding, the next second tooling 2 can be replaced immediately. The replacement operation only requires the tightening of the second butterfly nut 32 and the insertion and removal of the two second tooling 2. The operation is very convenient and the time required is very short, which helps to improve production efficiency.

[0021] like Figure 2 As shown, the highest point of the second butterfly nut 32 and the second stud 31 is not higher than the installation height of the first clamping block 22 and the second clamping block 23. That is to say, the height of the second butterfly nut 32 and the second stud 31 is lower than the height of the small end face of the loaded tapered roller. This does not affect the grinding operation of the small end face of the tapered roller. The present invention forms a notch space 26 between the first clamping block 22 and the second clamping block 23. The notch space 26 is set to correspond to the position of the splicing element 3. The setting of the notch space 26 can facilitate the operation of the splicing element 3 by the worker.

[0022] like Figure 3As shown, the first clamping block 22 and the second clamping block 23 are respectively installed on both sides of the base 21 in the width direction. Locking elements 25 are installed at both ends of the first clamping block 22 and the second clamping block 23. The first clamping block 22 and the second clamping block 23 are connected and fixed by the locking elements 25. The locking element 25 includes a first stud 251 and a first butterfly nut 252. The first stud 251 is fixedly connected to the side wall of the second clamping block 23. The first stud 251 is installed by transversely penetrating the first clamping block 22. The first butterfly nut 252 is threadedly connected to the first stud 251. In this invention, the first clamping block 22 can be positioned relatively far from the second clamping block 23. When the first clamping block 22 moves away from the second clamping block 23, the working cavity 24 becomes larger, allowing for the disassembly and replacement of the tapered roller workpiece. Tightening the first butterfly nut 252 pushes the first clamping block 22 towards the second clamping block 23. After the first clamping block 22 moves towards the second clamping block 23, the working cavity 24 shrinks, allowing for clamping of the sidewall close to the tapered roller. The arc surface of the working cavity 24 is adapted to the side conical surface of the tapered roller. Our company provides first clamping block 22 and second clamping block 23 assemblies of corresponding sizes for different models of tapered rollers. To ensure accurate forming of the working cavity 24, this utility model is designed... Positioning and mounting structures are designed for both the first clamping block 22 and the second clamping block 23. As described above, the second clamping block 23 is positioned and mounted using positioning protrusions 212 on the platform of the base 21. The first clamping block 22 has several insert feet 221 fixedly connected to its bottom surface. The insert feet 221 are horizontal L-shaped feet that are laterally fitted and inserted into the base 21 (horizontally inserted into the side wall of the base 21). Each working cavity 24 corresponds to one insert foot 221. The insert feet 221 can both form a connection between the first clamping block 22 and the base 21 and determine the connection position of the first clamping block 22. After installation, the first clamping block 22 will be able to accurately form several working cavities 24 after being spliced ​​with the second clamping block 23. In this utility model, the insertion stroke of the insertion foot 221 should be designed to meet the clamping requirements of the tapered roller. That is to say, the tapered roller workpiece should be clamped in place before the insertion foot 221 moves to the bottom. If the insertion foot 221 moves to the bottom but still cannot clamp the tapered roller, it should be considered that the first clamping block 22 and the second clamping block 23 assembly is not suitable for this type of tapered roller. In this case, a new first clamping block 22 and the second clamping block 23 assembly should be used. The two locking elements 25 of this utility model should be ensured to be fully locked and tightened.

[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
