Quick positioning and mounting device for bearings

Abstract

This utility model provides a bearing quick positioning and installation device, including a base, a fixed plate mounted on the upper surface of the base, a mounting seat at the center of the upper surface of the fixed plate, a workpiece mounted on the inner wall of the mounting seat, and a pressing top cover on the upper surface of the mounting seat. This utility model uses a cylinder to drive the connecting plate and the pressing top cover to descend. When the pressing top cover descends, it can press the corresponding moving blocks through inclined grooves, forcing the moving blocks in four directions to move synchronously towards the center point of the upper surface of the fixed plate. This drives multiple connecting rods and clamping plates to jointly position and clamp the workpiece on the inner wall of the mounting seat. Through this setting, synchronous positioning and fixing of the workpiece in four directions is achieved, avoiding the displacement and misalignment that can easily occur when limiting the bearing workpiece from a single direction. Furthermore, this design can adapt to workpieces of different sizes, making it highly practical.

[0002] Among numerous mechanical equipment, bearings serve as crucial support and transmission components, and their installation quality directly impacts the equipment's operational performance, precision, and service life. Traditional bearing installation methods often present numerous problems, making it difficult to meet the stringent efficiency and precision requirements of modern industrial production.

[0003] Currently, the common method for installing bearings is still manual assembly or installation with the help of simple tools. During the installation process, a positioning device is needed to position and fix the bearing to prevent it from shifting during processing. If it shifts, it may lead to insufficient processing accuracy of subsequent products, and in severe cases, it may cause the product to be completely scrapped. Existing positioning devices generally have clamping blocks on both sides of the bearing to clamp the outer side of the roller from the horizontal direction. This device means that it can only position and clamp the workpiece in a single horizontal direction, resulting in poor positioning effect.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a bearing quick positioning and installation device in order to achieve a more practical purpose. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a bearing quick positioning and installation device, including a base 1, a fixing plate 2 installed on the upper surface of the base 1, an installation seat 6 provided at the center of the upper surface of the fixing plate 2, a processing part 7 provided on the inner wall of the installation seat 6, a pressing top cover 5 provided on the upper surface of the installation seat 6, a connecting plate 17 installed on one side of the pressing top cover 5, an extension plate 19 installed on one side of the fixing plate 2, a cylinder 18 installed on the upper surface of the extension plate 19, the output end of the cylinder 18 is fixed to the connecting plate 17, by driving the cylinder 18 to run, its output end can drive the connecting plate 17 to descend, thereby driving the pressing top cover 5 to descend synchronously.

[0026] The inner wall of the mounting base 6 is equipped with a clamping assembly, which is used to perform multi-directional positioning and clamping of the workpiece 7.

[0027] The clamping assembly includes a slot 9, which is formed on the inner wall of the mounting base 6 and located on the outer side of the workpiece 7. Clamping plates 10 are symmetrically arranged on the four sides of the inner wall of the slot 9. Connecting rods 16 are mounted on one side of each clamping plate 10, with one end of each connecting rod 16 penetrating the mounting base 6 and extending to its outer side. A cross groove 3 is formed on the upper surface of the fixing plate 2. Moving blocks 4 are slidably mounted on the four sides of the inner wall of the cross groove 3. One side of each moving block 4 is fixed to the corresponding connecting rod 16. The inner surface of the pressing top cover 5 is... The four sides are provided with inclined grooves 8. The tops of the multiple moving blocks 4 are slidably connected to the inner wall of the inclined groove 8 on the corresponding side. When the top cover 5 is pressed down, the moving blocks 4 are pressed by the characteristics of the inclined groove 8. This allows the moving blocks 4 in the four directions to slide together towards the center point of the fixed plate 2 on the inner wall of the cross groove 3. The moving blocks 4 are connected to the connecting rod 16 and the clamping plate 10. By sliding the moving blocks 4 on the inner wall of the cross groove 3, the multiple clamping plates 10 can be driven to position and clamp the workpiece 7 from four directions.

[0028] The clamping plates 10 are provided with multiple grooves 13 on one side. A first spring 11 is installed on one side of the inner wall of each groove 13. An abutment post 12 is installed on one side of each first spring 11. One end of each abutment post 12 passes through the groove 13. The workpiece 7 is clamped and positioned by the multiple abutment posts 12. By setting the first spring 11 on the inner wall of the groove 13, each abutment post 12 can change its contour according to the shape of the bearing workpiece, so that this setting can adapt to various workpiece shapes for positioning and clamping.

[0029] The outer wall of each abutment post 12 is adapted to the inner wall of the corresponding groove 13, and the abutment posts 12 are all made of rubber. By making the abutment posts 12 of rubber, their soft texture can protect the workpiece 7 from damage when clamping it.

[0030] Among them, one side of the upper surface of multiple moving blocks 4 is provided with an inclined surface corresponding to the inner wall of the inclined groove 8. By setting the inclined surface, when the inclined groove 8 squeezes the moving blocks 4, the top of the moving blocks 4 can slide along the inner wall of the inclined groove 8.

[0031] The mounting base 6 has four fixed legs 20 installed at the four corners of its lower surface. The bottom of each fixed leg 20 is fixed to the upper surface of the fixed plate 2, thereby stabilizing the mounting base 6.

[0032] Each of the connecting rods 16 has a spring sleeve 14 on its outer wall. One side of each spring sleeve 14 is fixed to the outside of the mounting base 6. Each of the connecting rods 16 has a second spring 15 sleeved on its outer wall. One end of each second spring 15 is fixed to one side of the inner wall of the corresponding spring sleeve 14. With the second spring 15 sleeved on the outer wall of the connecting rod 16, after the connecting rod 16 drives the clamping plate 10 to perform absolute workpiece positioning and clamping, the top cover 5 rises and the moving block 4 loses pressure restriction. At this time, under the elastic force of the second spring 15, the connecting rod 16 can quickly rebound to the outside of the fixed plate 2, thereby preventing the connecting rod 16 from becoming blocked or jammed due to long-term operation.

[0033] The working principle of this embodiment is as follows: First, the workpiece 7 is placed in the mounting base 6. Then, the drive cylinder 18 is driven to run, and its output end drives the connecting plate 17 to descend, thereby causing the extrusion top cover 5 connected to the connecting plate 17 to descend synchronously. During the descent of the extrusion top cover 5, the inclined grooves 8 opened in the four directions on its inner side play a role in extruding the moving block 4 located on the four sides of the inner wall of the cross groove 3 and slidably connected to it. The moving block 4 is extruded, and its end slides towards the inner wall of the fixed plate 2 through the inclined groove 8. Its bottom slides towards the center point of the fixed plate 2 on the inner wall of the cross groove 3. Since the moving block 4 is fixed to the connecting rod 16, and the connecting rod 16 is connected to the clamping plate 10, multiple clamping plates 10 position and clamp the workpiece 7 in four directions.

[0034] Secondly, each clamping plate 10 has a groove 13 on one side, and a first spring 11 and an abutment post 12 are installed on the inner wall. The abutment post 12 passes through the groove 13 to clamp and position the workpiece 7. The setting of the first spring 11 allows the abutment post 12 to adapt to the shape of various workpieces according to the shape of the bearing workpiece for positioning and clamping. After the clamping work is completed, the top cover 5 is lifted and the moving block 4 loses pressure restriction. At this time, the second spring 15 sleeved on the outer wall of the connecting rod 16 causes the connecting rod 16 to drive the clamping plate 10 to quickly rebound to the outside of the fixed plate 2 under the action of elastic force, preventing the blockage and jamming phenomenon. The entire device drives the top cover 5 through the cylinder 18, and uses the cooperation of the inclined groove 8 and the moving block 4 to realize the multi-directional positioning and clamping of the workpiece 7 by the clamping assembly. In addition, the elastic design of the abutment post 12 enhances the adaptability and ensures the clamping effect and reliable operation of the equipment.

[0035] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
