Description

Technical Field

[0001] This utility model relates to the field of shaft and bearing assembly technology, specifically to a quick assembly structure for metal shafts and bearings. Background Technology

[0002] Bearings are components that support shafts, guiding their rotational movement and bearing the loads transmitted from the shaft to the machine frame. Bearings are widely used and critically important components in the machinery industry, serving as rotating shafts or moving parts in various machines. The assembly of the shaft and bearing typically requires a pressing device. This device generally involves placing the shaft on a fixed frame and then using a telescopic push rod to press the shaft and bearing together.

[0003] The existing patent publication number CN217647881U discloses a pressing device for assembling roller cores and bearings. By operating a stepper motor, the first bevel gear is driven to rotate, and the second bevel gear can drive the working plate and the placement frame to rotate. When the pressing component is used to complete the pressing work, the operator only needs to place the roller core body to be processed later on the subsequent placement frame to achieve continuous processing work.

[0004] Although the shaft core in the aforementioned patent can be rotated to change its position, the bearing needs to be manually reloaded after each pressing, which is quite troublesome and reduces assembly efficiency. At the same time, since the shaft core is fixed between the placement frame and the upper frame, it is not convenient to position the shaft core, which makes it difficult to ensure the accurate position of the shaft core and to ensure that the first telescopic push rod presses the bearing into the designated position. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a quick assembly structure for metal shaft cores and bearings, thereby facilitating bearing loading, improving assembly efficiency, and making it easier to position and fix the shaft core.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick assembly structure for metal shaft cores and bearings, comprising a machine base and a turntable movably mounted on the top of the machine base. A side mounting frame is fixedly mounted on the side of the machine base, and a pressing assembly is fixedly mounted on the outside of the side mounting frame. A fixing assembly and a positioning assembly arranged in a ring at equal intervals are fixedly mounted on the top of the turntable. The pressing assembly includes a telescopic push rod fixedly mounted inside the side mounting frame. A limiting frame is fixedly mounted on the inner side of the telescopic push rod. Clamping push rods are fixedly mounted on both the front and rear sides of the limiting frame. A clamping block located inside the limiting frame is fixedly mounted on the inner side of the clamping push rod. A guide frame is fixedly connected to the top of the limiting frame. A discharge port communicating with the guide frame is opened on the top of the limiting frame. A discharge port is opened on the top of the guide frame.

[0007] Preferably, the inner side of the clamping block is semi-circular, and the inner side of the clamping block is provided with an anti-slip coating.

[0008] Preferably, screws are threadedly installed on both the left and right sides of the guide frame, and a guide plate is movably installed on the inner side of the screw. The guide plate is located on the inner side of the guide frame, and a guide post penetrating the side wall of the guide frame is fixedly connected to the outer side of the guide plate.

[0009] Preferably, the outer side of the guide frame has an opening.

[0010] Preferably, the positioning component includes a guide frame fixedly installed inside the turntable. The guide frame is located inside the fixed component and corresponds one-to-one with the fixed component. A screw is movably installed inside the guide frame, and a slider is movably installed outside the screw. A stop plate is fixedly installed on the top of the slider. A handwheel is fixedly installed inside the screw, and a scale strip is fixedly installed on the outside of the guide frame.

[0011] Preferably, the fixing component includes a placement frame fixedly installed on the top of the turntable, a support plate fixedly connected to the top of the placement frame, a pressing push rod fixedly installed on the top of the support plate, and an upper pressing block located inside the support plate fixedly installed at the bottom of the pressing push rod.

[0012] Preferably, a servo motor is fixedly installed inside the machine tool, and the servo motor is fixedly connected to the turntable.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By operating the two clamping push rods to move the clamping blocks outward, the discharge port is opened, allowing the bearing in the discharge port to fall into the limit frame. The clamping push rods are then operated again to clamp the bearing on both sides, while the bearing above is pushed back to the discharge port by the clamping blocks. At the same time, the clamping blocks close the discharge port, thereby realizing automatic feeding of bearings and improving assembly efficiency.

[0015] 2. Based on the length of the shaft core, drive the screw one inside the guide frame to rotate. The rotation of the screw one then pushes the slider, causing the abutment to move in the inward and outward directions within the guide frame. The movement of the abutment can adjust its distance from the fixed component. The scale strip can be used to precisely set the position of the abutment to ensure accurate positioning of the shaft core after fixing, thus guaranteeing assembly stability.

Detailed Implementation

[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. 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.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This utility model provides a technical solution: a quick assembly structure for metal shaft cores and bearings, including a machine base 1 and a turntable 2 movably mounted on the top of the machine base 1. A side mounting bracket 3 is fixedly mounted on the side of the machine base 1, and a pressing assembly 4 is fixedly mounted on the outside of the side mounting bracket 3. A fixing assembly 5 and a positioning assembly 6 arranged in a ring at equal intervals are fixedly mounted on the top of the turntable 2. The pressing assembly 4 includes a telescopic push rod 41 fixedly mounted inside the side mounting bracket 3. A limit frame 42 is fixedly mounted on the inner side of the telescopic push rod 41. Clamping push rods 43 are fixedly mounted on both the front and rear sides of the limit frame 42. A clamping block 44 located inside the limit frame 42 is fixedly mounted on the inner side of the clamping push rod 43. A guide frame 45 is fixedly connected to the top of the limiting frame 42. The top of the limiting frame 42 has a discharge port 46 that communicates with the guide frame 45. The top of the guide frame 45 has a discharge port 47. The bearings enter the guide frame 45 one by one through the discharge port 47. Simultaneously, the two clamping push rods 43 are operated to drive the clamping block 44 to move outward, so that the discharge port 46 is opened, allowing the bearing in the discharge port 47 to fall into the limiting frame 42. The clamping push rods 43 are operated again to make the clamping blocks 44 on both sides clamp the bearing. The bearing above is pushed back to the discharge port 47 by the clamping block 44. At the same time, the clamping block 44 closes the discharge port 46, thereby realizing automatic feeding of bearings and improving assembly efficiency.

[0024] The inner side of the clamping block 44 is semi-circular and has an anti-slip coating, which can better fit the outer surface of the bearing, increase the contact area with the bearing, and ensure stability during clamping. The top of the clamping block 44 is arc-shaped, which can effectively push the upper bearing back into the discharge port 47. The clamping block 44 can be replaced to adapt to bearings of different sizes. The anti-slip coating increases the friction between the clamping block 44 and the bearing, preventing slippage during the clamping and transfer of the bearing.

[0025] Both sides of the guide frame 45 are threaded with screw rods 48. A guide plate 49 is movably installed on the inner side of the screw rods 48. The guide plate 49 is located inside the guide frame 45. A guide post 410 that penetrates the side wall of the guide frame 45 is fixedly connected to the outer side of the guide plate 49. By rotating the screw rods 48, the position of the guide plate 49 inside the guide frame 45 can be adjusted. In this way, the internal space of the guide frame 45 can be adjusted according to the size of the bearing to ensure that the bearing moves stably inside the guide frame 45.

[0026] An opening 411 is provided on the outer side of the guide frame 45, which allows for easy observation of the bearing position and usage inside the guide frame 45.

[0027] Please see Figure 1 and Figure 5The positioning component 6 includes a guide frame 61 fixedly installed inside the turntable 2. The guide frame 61 is located inside the fixing component 5 and corresponds one-to-one with the fixing component 5. A screw 62 is movably installed inside the guide frame 61, and a slider 63 is movably installed outside the screw 62. A stop plate 64 is fixedly installed on the top of the slider 63. A handwheel 65 is fixedly installed inside the screw 62, and a scale bar 66 is fixedly installed on the outside of the guide frame 61. By rotating the handwheel 65, the screw 62 inside the guide frame 61 is driven to rotate according to the length of the shaft core. The rotation of the screw 62 then pushes the slider 63, causing the stop plate 64 to move in the inward and outward directions within the guide frame 61. The movement of the stop plate 64 can adjust its distance from the fixing component 5. The scale bar 66 can be used to precisely set the position of the stop plate 64 to ensure accurate positioning of the shaft core after fixing and to guarantee assembly stability.

[0028] The fixing component 5 includes a placement frame 51 fixedly installed on the top of the turntable 2. A support plate 52 is fixedly connected to the top of the placement frame 51. A clamping push rod 53 is fixedly installed on the top of the support plate 52. An upper pressure block 54 located inside the support plate 52 is fixedly installed at the bottom of the clamping push rod 53. The upper pressure block 54 is moved down by the clamping push rod 53 to clamp the shaft core between the placement frame 51 and the upper pressure block 54, thus firmly fixing the shaft core. When quickly assembling the metal shaft core and bearing, the shaft core can maintain a stable position, avoiding displacement or shaking during the assembly process, effectively improving the assembly accuracy and efficiency. At the same time, the upper pressure block 54 and the placement frame 51 are replaceable to accommodate shaft cores of different specifications and sizes, enhancing versatility.

[0029] Please see Figure 4 The machine tool 1 is equipped with a servo motor 7, which is fixedly connected to the turntable 2. The servo motor 7 can precisely control the rotation angle and speed of the turntable 2, so as to realize the intermittent rotation of the turntable 2 to switch the position of the ring-shaped fixed component 5, thereby improving the assembly efficiency.

[0030] Working principle: By rotating the handwheel 65 according to the length of the shaft core, the screw 62 located inside the guide frame 61 is rotated. The rotation of the screw 62 drives the slider 63 to move the abutment plate 64 inside the guide frame 61 to slide inward and outward. The movement of the abutment plate 64 changes the distance between it and the fixing component 5. The position of the abutment plate 64 can be accurately adjusted by checking the scale bar 66. Then, the shaft core is placed between the placement frame 51 and the upper pressure block 54. Then, the pressing push rod 53 drives the upper pressure block 54 to move down, clamping the shaft core between the placement frame 51 and the upper pressure block 54. The inner end of the shaft core abuts against the outer side of the abutment plate 64, which facilitates the determination of the fixed position of the shaft core and improves the accuracy and stability of the assembly.

[0031] By placing the bearings one by one into the guide frame 45 from the discharge port 47, and synchronously controlling the two clamping push rods 43 to move the clamping blocks 44 outward, the bottom of the discharge port 46 is opened, allowing the bearings in the discharge port 47 to fall into the limiting frame 42. Then, the clamping push rods 43 are extended again to clamp the bearings on both sides of the clamping blocks 44. The bearing located above the currently clamped bearing is pushed back into the discharge port 47 by the clamping blocks 44, and the discharge port 46 is blocked by the clamping blocks 44, thus completing the automatic feeding of the bearings. The turntable 2 is rotated to the bearing direction by the shaft core rotation servo motor 7, and the limiting frame 42 is pushed inward by the telescopic push rod 41 to press and fit the bearing onto the outside of the shaft core to complete the assembly. The above is the working process of the entire device, and the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
