AI Technical Summary
The existing bearing grinder lacks fine-tuning devices, which leads to the inaccuracy of the workpieces of the micro-bearing inner rings being unable to accurately adjust the eccentricity during the grinding process, affecting the grinding roundness of the workpiece.
A bearing grinder workpiece positioning support fine-tuning mechanism is designed, using a central plate, an adjustable lower support seat and upper support seat, fine screws and lock nuts. Through the fine-tuning function of fine-tuning screws and the fixing function of lock nuts, the precise adjustment of the position of the inner ring workpiece of the bearing is achieved.
Through this fine-tuning mechanism, the eccentricity of the inner ring workpiece of the bearing can be accurately adjusted, ensuring the ideal result of grinding roundness, and improving the grinding accuracy of the workpiece.

Description
Technical Field
[0001] The utility model relates to the technical field of bearing processing, in particular to a fine adjustment mechanism for workpiece positioning and support of a bearing grinding machine. Background Technique
[0002] Generally, the inner ring workpiece of a miniature bearing is installed in the third quadrant at the center of the spindle of a bearing grinding machine, with an eccentricity of about 0.05 - 0.15 mm. After the bearing grinding machine is powered on, the spindle sucks the inner ring of the miniature bearing by electromagnetic adsorption. The inner ring of the miniature bearing is adjusted by two upper and lower supports. Due to the absence of a fine adjustment device, the adjustment is inaccurate, and the desired eccentricity cannot be achieved, resulting in the grinding roundness of the workpiece not reaching the ideal result. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a fine adjustment mechanism for workpiece positioning and support of a bearing grinding machine in view of the above-mentioned prior art deficiencies.
[0004] To solve the above technical problems, the technical solution adopted by the utility model is:
[0005] A fine adjustment mechanism for workpiece positioning and support of a bearing grinding machine includes a center plate, on which an adjustable lower support seat and an upper support seat are connected. The lower support seat is located below the center plate, and the upper support seat is located on the side of the center plate. A lower support member is arranged in the lower support seat and slides in the lower support seat. An upper support member is arranged in the upper support seat and slides in the upper support seat. One ends of the lower support member and the upper support member respectively extend out of the lower support seat and the upper support seat, and support heads are processed. The tails of the lower support seat and the upper support seat are connected with adjusting screws, and the adjusting screws are connected with the lower support seat and the upper support seat by fine pitch threads. A locking nut is connected to the adjusting screw.
[0006] Further, adjustment grooves are processed on the center plate, and sliding seats are arranged at the bottoms of the lower support seat and the upper support seat. The sliding seats slide and adjust in the adjustment grooves. First threaded holes are processed on the lower support seat and the upper support seat, and the lower support seat and the upper support seat are fixed by screw one at the first threaded holes.
[0007] Further, the sliding seat and the adjustment groove adopt a dovetail structure.
[0008] Further, enlarged holes are processed at both ends of the adjustment groove.
[0009] Further, sliding grooves are processed on the lower support seat and the upper support seat, and the lower support member and the upper support member are located in the sliding grooves and slide. Second threaded holes are processed in the sliding grooves, and waist-shaped grooves are processed on the surfaces of the lower support member and the upper support member. The waist-shaped grooves are connected with the second threaded holes by screw two.
[0010] Compared with the prior art, a fine-tuning mechanism for workpiece positioning and support of a bearing grinding machine according to the present utility model uses a fine-thread screw to fine-tune the support member. After reaching the desired position, it is locked by a nut, so that the workpiece is in the corresponding quadrant position, ensuring the grinding roundness. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solutions in the embodiments of the present utility model will be clearly and completely described below.
[0015] As Figure 1 and Figure 2 shown, a fine-tuning mechanism for workpiece positioning and support of a bearing grinding machine includes a central disk 1. An adjustable-position lower support seat 2 and an upper support seat 3 are connected to the central disk 1. The lower support seat 2 is located below the central disk 1, and the upper support seat 3 is located on the side of the central disk 1. A lower support member 4 is arranged in the lower support seat 2, and the lower support member 4 slides in the lower support seat 2. An upper support member 5 is arranged in the upper support seat 3, and the upper support member 5 slides in the upper support seat 3. One ends of the lower support member 4 and the upper support member 5 respectively extend out of the lower support seat 2 and the lower support seat 3, and a support head 6 is processed. The support head 6 supports the inner ring workpiece of the bearing. Adjusting screws 7 are connected to the tails of the lower support seat 2 and the upper support seat 3. The adjusting screws 7 are connected to the lower support seat 2 and the lower support seat 3 by fine-thread threads. By using fine-thread threads, it is convenient to finely adjust the position of the inner ring workpiece of the bearing. A locking nut 8 is connected to the adjusting screw 7.
[0016] In this embodiment, an arc-shaped adjustment groove 9 is machined on the central disk 1, and sliding seats 10 are arranged at the bottoms of the lower support base 2 and the upper support base 3. The sliding seats 10 slide and adjust within the arc-shaped adjustment groove 9. Among them, the sliding seats 10 and the arc-shaped adjustment groove 9 adopt a dovetail structure. Enlarged holes 11 are machined at both ends of the arc-shaped adjustment groove 9. By providing the enlarged holes 11, it is convenient for the sliding seats 10 at the bottoms of the lower support base 2 and the upper support base 3 to enter the arc-shaped adjustment groove 9. First threaded holes 12 are machined on the lower support base 2 and the upper support base 3. After the lower support base 2 and the upper support base 3 are adjusted in position, the lower support base 2 and the upper support base 3 are fixed on the central disk 1 through screws at the first threaded holes 12.
