Description
Technical Field
The utility model belongs to the technical field of the bearing holder detects, especially, nylon holder pocket hole radius detects uses clamping device.
Background
Cage (i.e., bearing cage, also known as a bearing retainer) refers to a bearing component that partially encases all or part of the rolling elements and moves with them to isolate the rolling elements and generally also guide and retain them within the bearing.
The machining precision of the radius of the cage pocket directly influences the rotation flexibility of the finished bearing, so that the radius of the cage pocket needs to be measured by a profilometer. The retainer made of metal materials can be fixed on a detection platform of the profiler through a magnet or a chuck, the nylon retainer is made of non-metal materials, the nylon retainer cannot be fixed through the magnet like the metal retainer during detection, and if the nylon retainer is fixed through the chuck, the deformation of the retainer is large, so that the measurement accuracy of the nylon retainer is affected. When an existing bearing manufacturer measures the radius of a pocket of a small nylon retainer, the nylon retainer is fixed on a detection table through multipurpose glue, but the detection method is low in efficiency, and the nylon retainer cannot be used normally after being detected, so that resource waste is caused.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a nylon retainer is less influenced, can be fixed in the nylon retainer and examine on the test table and do not destroy the nylon retainer and make it can continue the nylon retainer pocket radius detection with pressing from both sides dress device of normal use.
In order to realize the purpose, the utility model discloses a technical scheme is: the clamping device for detecting the radius of the pocket of the nylon retainer comprises a support platform for placing the retainer, wherein a positioning rod is vertically arranged on the support platform, a pressing piece used for pressing and fixing the retainer on the support platform is arranged on the positioning rod in a sliding mode, and a limiting nut used for limiting the pressing piece is arranged on the positioning rod.
By adopting the scheme, when in use, the nylon retainer is placed on the bracket platform along the positioning rod, the pressing piece on the positioning rod slides to the nylon retainer and is limited by the limiting nut, the pressing piece is prevented from continuously sliding, and the pressing piece can form pressing force on the nylon retainer (the pressing piece is generally pressed on the connecting part between the pocket hole of the retainer and the pocket hole, so that the measurement of the subsequent pocket hole is not influenced), thereby preventing the nylon retainer from moving on the bracket platform and achieving the purpose of stabilizing the retainer, the retainer pressing device mainly has the advantages that the retainer pressing device can form pressing force on the retainer through the limiting effect of the limiting nut on the retainer pressing device, the pressing force generated in the pressing process of the retainer pressing device cannot be too large, and an operator can control the size of the pressing force by adjusting the limiting nut, so that the pressing force can be kept under the condition that the retainer is not damaged. The utility model discloses simple structure, operation convenient to use.
As a further setting of the utility model, the pressing piece with the butt elastic component between the stop nut.
By adopting the scheme, the operation can be further simple by pressing the elastic part between the pressing part and the limiting nut, namely, the limiting nut is not required to be repeatedly adjusted to prevent the retainer from deforming, the pressing part forms the pressing force for the retainer by depending on the elastic force of the elastic part, the elastic force of the elastic part is smaller than the deformation force of the nylon retainer, so that the nylon retainer cannot deform, and the detection precision is improved to a certain extent.
As a further setting of the utility model, the pressing part is established on the locating lever and can be followed locating lever circumferential direction's first crossbeam and second crossbeam including the cover, all be provided with on first crossbeam and the second crossbeam and be used for supporting the depression bar that presses on the holder.
Adopt above-mentioned scheme, even first crossbeam and second crossbeam, and first crossbeam and second crossbeam can be followed locating lever circumferential direction and be applicable to the holder of different pocket hole numbers for making the press part, because existing pocket hole is the holder of even number symmetry form, also there is the holder that the pocket hole is odd number asymmetry form, rely on first crossbeam and second crossbeam to follow locating lever pivoted characteristic and make this product be applicable to the holder that the pocket hole is even number symmetry form promptly, also be applicable to the holder that the pocket hole is odd number asymmetry form, application scope is wider.
As a further setting of the utility model, the depression bar slides and sets up on first crossbeam or the second crossbeam, all be provided with the spout that is used for the depression bar to slide on first crossbeam and the second crossbeam, the one end of depression bar is worn to establish in the spout and to the spout outer extension be formed with the stopper that first crossbeam or second crossbeam contradict, the spiro union on the depression bar have with the stopper cooperation presss from both sides the lock nut of tightly on first crossbeam or second crossbeam.
By adopting the scheme, the pressing rod on the first cross beam and the second cross beam can be adjusted, so that the nylon retainer is suitable for nylon retainers with different diameters, the application range is wider, the adjusted pressing rod can be locked and positioned through the locking nut, the pressing rod is prevented from moving, and the use is more convenient.
The present invention will be further described with reference to the accompanying drawings.
