AI Technical Summary
In the existing technology, pneumatic or electric grippers are prone to damaging the product surface when gripping large or heavy bearing rings, resulting in defective products.
The non-destructive centering gripper mechanism uses a rotary motor to drive three L-shaped grippers to move synchronously. The support plate holds the bottom of the bearing ring for gripping, avoiding friction damage.
This reduces damage to the outer surface of the bearing race, improves the product qualification rate, and protects the race surface.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing ring manufacturing technology, and more specifically, to a non-damaging centering gripper mechanism for bearing rings. Background Technology
[0002] During the production or testing of bearing rings, the processing and production equipment needs to load and unload materials. Currently, for some smaller rings, pneumatic clamps are used for loading and unloading. However, when the size is larger and the product is heavier, pneumatic clamps are generally insufficient. Some mechanisms use motor-driven clamps for loading.
[0003] Some ring clamping methods use pneumatic or electric internal supports, which use the principle of friction to clamp the product. Over time, it has been found that this often damages the product surface, leaving clamping marks and easily resulting in defective products. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a bearing ring non-damaging centering gripper mechanism.
[0005] To achieve the above objectives, this utility model provides a non-destructive centering gripper mechanism for bearing rings. Its structure includes a base with three outwardly extending base plates at the bottom. The base is hollow, and the base plates have clamping grooves communicating with the interior of the base. The innovation lies in the fact that the structure also includes three clamping rods. Each clamping groove has a slidable connecting block inside. A rotary motor driving the three connecting blocks to move synchronously is mounted on the base. The three clamping rods are vertically fixed to the bottom of the connecting blocks, and a support plate is fixed to the bottom of each clamping rod. The clamping rods and support plates form an L-shape.
[0006] Furthermore, the interior of the aforementioned clamping groove is equipped with a slide rail, and the top of the connecting block is equipped with a main slider, which is slidably mounted on the slide rail.
[0007] Furthermore, the slide rail is provided with a sliding secondary slider, and a stabilizing block is provided at the bottom of the secondary slider. The stabilizing block and the connecting block are both provided with through-hole adjusting nuts. Both adjusting nuts are connected to lead screws. One end of the lead screw is provided with a helical bevel gear, and the output end of the rotary motor is provided with bevel gears. The helical bevel gears are meshed with the bevel gears.
[0008] Furthermore, the bottom of the aforementioned pallet end is provided with a slope, which is inclined upwards.
[0009] The technical effects and advantages of this utility model are as follows: This utility model uses a support plate to hold the bearing ring at the bottom. Compared with the traditional method of using friction to clamp the bearing ring, this clamping method can reduce damage to the outer surface of the bearing ring and protect the surface of the bearing ring.

[0011] Figure 2 This is a structural diagram of the internal structure of the base of this utility model. Detailed Implementation
[0012] 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.
[0013] like Figures 1 to 2 In one specific embodiment of this utility model, the structure includes a base 1, with three outwardly extending base plates 11 at the bottom of the base 1. The interior of the base 1 is hollow, and the base plates 11 are provided with clamping grooves 12 that communicate with the interior of the base 1. The structure also includes three clamping rods 2. Each clamping groove 12 is provided with a slidable connecting block 13. The base 1 is provided with a rotary motor 14 that drives the three connecting blocks 13 to move synchronously. The three clamping rods 2 are respectively vertically fixed to the bottom of the connecting blocks 13, and each clamping rod 2 is fixed with a support plate 15. The clamping rods 2 and the support plate 15 are formed in an L shape.
[0014] In this utility model, the process of clamping the bearing ring is as follows: turn on the rotary motor 14, which synchronously drives the three clamping rods 2 to move outward. Then, the three clamping rods 2 are placed on the outside of the bearing ring. Finally, the rotary motor 14 drives the three clamping rods 2 to move inward, so that the ends of the three support plates 15 are lifted at the bottom of the bearing ring, thereby clamping the bearing ring.
[0015] In this invention, the support plate 15 is used to support the bottom of the bearing ring. Compared with the traditional method of clamping the bearing ring by friction, this clamping method can reduce damage to the outer surface of the bearing ring and protect the surface of the bearing ring.
[0016] In this utility model, as a preferred embodiment, the interior of the clamping groove 12 is provided with a slide rail 3, and the top of the connecting block 13 is provided with a main slider 31, which is slidably mounted on the slide rail 3.
[0017] In this utility model, as a preferred embodiment, the slide rail 3 is provided with a slidable secondary slider 32, the bottom of the secondary slider 32 is provided with a stabilizing block 33, the stabilizing block 33 and the connecting block 13 are both provided with through adjusting nuts 34, and both adjusting nuts 34 are connected with lead screws 35. One end of the lead screw 35 is provided with a helical bevel gear 36, and the output end of the rotary motor 14 is provided with bevel gears 37. The helical bevel gears 36 are meshed with the bevel gears 37.
[0018] In this invention, when the rotary motor 14 rotates, it synchronously drives the rotation of the three lead screws 35 through the meshing of the bevel gears 37 and the three helical bevel gears 36. When the lead screws 35 rotate, the main slider 31 and the auxiliary slider 32 slide on the slide rail 3, thereby ensuring the stability of the movement of the clamping rod 2.
[0019] In this utility model, as a preferred embodiment, the bottom of the end of the aforementioned pallet 15 is provided with an inclined surface 4, which is inclined upward.
[0020] In this invention, when the bearing ring is fitted inside the clamping rod 2, the inclined surface 4 prevents the bottom of the support plate 15 from contacting the upper end face of the bearing ring, thereby further protecting the bearing ring.
[0021] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
