Description

Technical Field

[0001] This utility model belongs to the field of press-fitting technology, and in particular relates to a high-precision press-fitting tool for bearing guide pillars. Background Technology

[0002] The high-precision press-fit tool for bearing guide pillars is a device used for precision assembly and press-fitting operations. It is typically used in industrial fields that require high-precision positioning and press-fitting, such as electronic component assembly and mechanical assembly. Its main feature is that it achieves high-precision positioning and press-fitting through guide pillar guidance and extraction technology.

[0003] According to a public disclosure (CN103414289 A), a commutator pressing device and pressing method for a skewed iron core rotor includes a pressing base, a positioning post, a guide post, a positioning ring, a spring, and a pressing head. The pressing head is located above the positioning post. The positioning post and the guide post are respectively set on the pressing base. A positioning sleeve is provided on the guide post. The positioning sleeve is provided with a cylindrical pin for fixing the skewed iron core rotor. The positioning ring is fixed on the pressing base by a positioning key B. The spring is fitted on the guide post and placed between the positioning sleeve and the pressing base.

[0004] In the aforementioned application, the cooperation between components such as the press-fit base and the positioning ring makes it difficult to prevent the material from shaking during the press-fitting process, which leads to a reduction in the screw press-fitting accuracy and needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide a high-precision pressing tool for bearing guide pillars. Through the cooperation of components such as the clamping plate, motor, and bidirectional lead screw inside the limiting and anti-displacement assembly, the relative movement of the bidirectional lead screw and the threaded sleeve is achieved. The clamping plate can clamp the material in a suitable position under precise control, ensuring that the material does not shift or shake during the pressing process, thereby guaranteeing the pressing accuracy. The displacement of the threaded sleeve is limited by the limiting rod, ensuring that the threaded sleeve can only move along a specific track, thereby stabilizing the clamping plate and preventing the material from shaking during the pressing process, thus solving the existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a high-precision press-fitting tool for bearing guide columns, comprising a bracket, an adjustable crossbeam on the side of the bracket, a limit anti-displacement component on the side of the bracket, the limit anti-displacement component including a movable clamping plate on the side of the bracket, a jack at the bottom of the bracket, a limit post penetrating through the side of the bracket, a support rod fixedly connected to the side of the bracket, a motor fixedly connected to the side of the support rod, a bidirectional lead screw fixedly connected to the output shaft of the motor, a threaded sleeve threadedly connected to the circumference of the bidirectional lead screw, a limit rod fixedly connected to the side of the motor, the end of the limit rod away from the motor penetrating through the side of the threaded sleeve, a long rod fixedly connected to the top of the threaded sleeve, and a clamping plate fixedly connected to the bottom of the long rod.

[0008] Furthermore, the surface of the motor is provided with a switch, and there are two threaded sleeves, clamping plates, and long rods, which are symmetrical to each other along the vertical central axis of the bidirectional screw. The provision of two clamping plates, long rods, and threaded sleeves is beneficial to clamp both sides of the material to be pressed at the same time, further reducing displacement.

[0009] Furthermore, the clamping plate is located below the jack, several limiting posts are provided, and the adjustable crossbeam is located on the side of the movable clamping plate. The design of the limiting posts is beneficial for limiting the position of the bracket.

[0010] Furthermore, a heat dissipation assembly is provided on the side of the bracket. The heat dissipation assembly includes a crossbar, one end of which is fixedly connected to the side of the bracket. A rotating rod is rotatably connected to the side of the crossbar, a short rod is fixedly connected to the side of the crossbar, and a protective shell is fixedly connected to the side of the short rod. Fan blades are fixedly connected to the circumferential surface of the rotating rod, and a thin rod is fixedly connected to the circumferential surface of the rotating rod. An actuating rod is fixedly connected to the side of the threaded sleeve. The fan blades generate rotating airflow to dissipate heat from the material being pressed.

[0011] Furthermore, the thin rod is located on the displacement trajectory of the trigger rod, and the fan blade is located on the inner wall of the protective shell. This design is beneficial for protecting the fan blade.

[0012] Furthermore, a torsion spring is fixedly connected to the circumferential surface of the rotating rod, and the end of the torsion spring away from the rotating rod is fixedly connected to the inner wall of the protective shell. The design of the torsion spring is conducive to automatic reset when the rotating rod is not driven to rotate.

[0013] Furthermore, the fan blades are located on the side of the support, and there are several fan blades arranged in a circumferential array on the circumferential surface of the rotating rod. This design allows for direct airflow onto the material on the support.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes the interplay between components such as the clamping plate, motor, and bidirectional lead screw within the limiting and anti-displacement assembly. Through the relative movement of the bidirectional lead screw and the threaded sleeve, the clamping plate can precisely control the material to hold it in the appropriate position, ensuring that the material does not shift or shake during pressing, thus guaranteeing pressing accuracy. Furthermore, the limiting rod restricts the displacement of the threaded sleeve, ensuring that it can only move along a specific track, thereby stabilizing the clamping plate and preventing material from shaking during pressing.

[0016] This invention utilizes the interaction between components such as fan blades, rotating rods, and thin rods within the heat dissipation assembly to achieve the effect of pressure and friction. Equipment and materials generate heat, and if this heat is not dissipated in time, it may lead to overheating, affecting the device's accuracy and performance. The rotation of the fan blades effectively directs airflow to the side of the support, thereby carrying away the heat generated during the pressing process and ensuring the equipment operates at a relatively stable and suitable temperature. Timely heat dissipation avoids errors caused by overheating, thus improving the overall pressing accuracy and stability.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] Please see Figure 1-5 This utility model is a high-precision pressing tool for bearing guide columns, including a bracket 1. An adjustable crossbeam 2 is provided on the side of the bracket 1. A limit anti-displacement component 3 is provided on the side of the bracket 1. The limit anti-displacement component 3 includes a movable clamping plate 31, which is located on the side of the bracket 1. A jack 32 is provided at the bottom of the bracket 1. A limit post 33 passes through the side of the bracket 1. A support rod 34 is fixedly connected to the side of the bracket 1. A motor 35 is fixedly connected to the side of the support rod 34. A bidirectional lead screw 36 is fixedly connected to the output shaft of the motor 35. A threaded sleeve 37 is threadedly connected to the circumference of the bidirectional lead screw 36. A limit rod 310 is fixedly connected to the side of the motor 35. The end of the limit rod 310 away from the motor 35 passes through the side of the threaded sleeve 37. A long rod 38 is fixedly connected to the top of the threaded sleeve 37. A clamping plate 39 is fixedly connected to the bottom of the long rod 38.

[0028] The surface of the motor 35 is provided with a switch 311. There are two threaded sleeves 37, clamping plates 39 and long rods 38, which are symmetrical to each other along the vertical central axis of the bidirectional lead screw 36. The two clamping plates 39, long rods 38 and threaded sleeves 37 are conducive to clamping both sides of the material to be pressed at the same time, further reducing displacement.

[0029] The clamping plate 39 is located below the jack 32, and several limiting posts 33 are provided. The adjustable crossbeam 2 is located on the side of the movable clamping plate 31. The design of the limiting posts 33 is conducive to limiting the support 1.

[0030] A heat dissipation component 4 is provided on the side of the bracket 1. The heat dissipation component 4 includes a crossbar 41. One end of the crossbar 41 is fixedly connected to the side of the bracket 1. A rotating rod 44 is rotatably connected to the side of the crossbar 41. A short rod 43 is fixedly connected to the side of the crossbar 41. A protective shell 42 is fixedly connected to the side of the short rod 43. A fan blade 45 is fixedly connected to the circumferential surface of the rotating rod 44. A thin rod 47 is fixedly connected to the circumferential surface of the rotating rod 44. An actuating rod 48 is fixedly connected to the side of the threaded sleeve 37. The fan blade 45 generates rotating airflow to blow air and dissipate heat on the material being pressed.

[0031] The thin rod 47 is located on the displacement trajectory of the trigger rod 48, and the fan blade 45 is located on the inner wall of the protective shell 42. This design is beneficial to the protection of the fan blade 45.

[0032] A torsion spring 46 is fixedly connected to the circumferential surface of the rotating rod 44. The end of the torsion spring 46 away from the rotating rod 44 is fixedly connected to the inner wall of the protective shell 42. The design of the torsion spring 46 is conducive to automatic reset when the rotating rod 44 is not driven to rotate.

[0033] The fan blades 45 are located on the side of the support 1. There are several fan blades 45, which are arranged in a circumferential array on the circumferential surface of the rotating rod 44. This design allows the material on the support 1 to be blown directly.

[0034] A specific application of this embodiment is as follows: The material to be pressed is placed on top of the movable clamping plate 31, and the material is pressed using the jack 32. To prevent the material from shaking during the pressing process, the switch 311 is pressed to start the motor 35, causing it to rotate forward. The forward rotation of the motor 35 drives the bidirectional lead screw 36 to rotate forward, which in turn drives the two threaded sleeves 37 to move relative to each other in the same direction. The limiting rod 310 restricts the threaded sleeves 37, ensuring that they can only move left and right following the rotation of the bidirectional lead screw 36. The relative movement of the threaded sleeves 37 drives the long rod 38 and the clamping plate 39 to move relative to each other in the same direction. The two clamping plates 39 move relative to each other in the same direction, clamping the material on both sides located in the middle of the clamping plates 39. Then, the jack 32 is used to press down. Through the relative movement of the bidirectional lead screw 36 and the threaded sleeve 37, the clamping plates 39 can clamp the material in the appropriate position under precise control, ensuring that the material does not shift or shake during the pressing process, thus ensuring the pressing accuracy. After pressing the switch 311 to start the motor 35, the rotation of the bidirectional lead screw 36 drives the relative movement of the threaded sleeve 37, and the displacement of the threaded sleeve 37 is limited by the limit rod 310, ensuring that the threaded sleeve 37 can only move along a specific track, thereby stabilizing the clamping plates 39 and preventing the material from shaking during the pressing process.

[0035] The relative movement of the threaded sleeve 37 causes the actuating rod 48 to move. The thin rod 47 is located on the movement trajectory of the actuating rod 48. When the actuating rod 48 moves, it squeezes the thin rod 47, causing the thin rod 47 to rotate. This rotation of the rotating rod 44 causes the fan blades 45 to rotate. The fan blades 45 are located on the inner wall of the protective shell 42 and rotate inside the protective shell 42, generating corresponding wind force. Since the fan blades 45 are located on the side of the bracket 1, the wind force generated by the rotation of the fan blades 45 will blow onto... On the side of bracket 1, air is blown to dissipate heat from the material being pressed onto the side of bracket 1. During the pressing process, the equipment and materials generate heat due to pressure and friction. If this heat is not dissipated in time, it may cause the equipment to overheat, thereby affecting the accuracy and performance of the device. The rotation of the fan blades 45 can effectively blow air onto the side of bracket 1, thereby removing the heat generated during the pressing process and ensuring that the equipment is at a relatively stable and suitable working temperature. Timely heat dissipation can avoid errors caused by overheating, thereby improving the overall pressing accuracy and stability.
