Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to a bearing limiting mechanism for stamping equipment. Background Art

[0002] Stamping equipment is a forging device that is often widely used in die stamping processes. It is a device that drives the flywheel through an electric motor, and drives the crank-connecting rod mechanism through a clutch and transmission gear to move the slider up and down, thereby driving the die to form the sheet.

[0003] During the operation of the stamping equipment, due to objective reasons such as frequent acceleration and deceleration of the machine working conditions and clearance fit of the bearing installation, the bearings used in the transmission structure of the equipment will experience a phenomenon in which the outer ring of the bearing slowly rotates relative to the crossbeam during operation. The long-term existence of this self-rotation phenomenon will cause wear of the crossbeam and the outer ring of the bearing, thereby affecting the working accuracy of the equipment, causing debris to contaminate the oil, and even causing the equipment to fail to work normally.

[0004] In order to solve the problem of self-rotation of the outer ring of the bearing, it is necessary to limit the outer ring of the bearing. The existing bearing outer ring rotation limiting method includes a rivet fixing method (such as publication number CN215567386U). Although it can limit the rotation of the outer ring of the bearing, it is necessary to perform grooving, hole drilling and other processing operations on the outer ring of the bearing, and the processing process is complicated and costly. In addition, the existing bearing outer ring rotation limiting method not only limits the rotation of the outer ring of the bearing by rivets, but also limits the position of the outer ring of the bearing. Since the high-speed shaft of the stamping equipment will have a slight axial movement (axial movement) during work, the bearing (self-aligning bearing) connected to the high-speed shaft will also have axial movement to share the load. If the rivet limiting method is used, it will hinder the axial movement of the bearing and affect the working performance of the bearing. It is not suitable for bearing limiting of stamping equipment. Utility Model Content

[0005] In order to solve the technical problem existing in the above-mentioned background technology that the outer ring of the bearing cannot be restricted from self-rotating while ensuring the working performance of the bearing, the utility model provides a bearing limiting mechanism for stamping equipment.

[0006] The technical solution of this utility model is as follows:

[0007] The utility model provides a bearing limiting mechanism for stamping equipment, comprising: a mounting seat, the mounting seat is slidably arranged on a cross beam body along the axial direction of the bearing, the mounting seat is located directly below the bearing, a limiting top screw is detachably installed on the mounting seat, the limiting top screw is vertically arranged, the top of the limiting top screw is inserted into the lubricating oil hole of the outer ring of the bearing, and can fix the outer ring of the bearing so that it no longer rotates relative to the cross beam body on the basis of ensuring the normal operation of the equipment, thereby preventing the cross beam body from being damaged by the outer ring of the bearing and the outer ring of the bearing from being worn, and at the same time, when the bearing moves along its axial direction, the mounting seat will slide along the axial direction of the bearing, and the mounting seat and the limiting top screw will not completely limit the axial movement of the outer ring of the bearing, thereby ensuring that the working performance of the bearing will not be restricted.

[0008] Preferably, a positioning groove is provided on the cross beam body, the positioning groove extends along the axial direction of the bearing, the shape of the positioning groove matches the mounting seat, the mounting seat is slidably arranged in the positioning groove, and the positioning groove can be used to limit the position of the mounting seat and play a guiding role at the same time.

[0009] Preferably, the positioning groove is located directly below the bearing to limit the mounting seat below the bearing.

[0010] Preferably, a threaded hole is provided on the mounting seat, an outer wall of the limiting top screw is provided with an external thread, and the limiting top screw is threadedly connected to the threaded hole, which facilitates the connection between the mounting seat and the limiting top screw and facilitates the replacement of the limiting top screw.

[0011] Preferably, the limit screw is a conical structure, and the diameter of the limit screw gradually increases from top to bottom, which not only facilitates the connection between the limit screw and the lubricating oil hole on the outer ring of the bearing, but also facilitates the sealing of the lubricating oil hole to prevent leakage of the lubricating oil, thereby ensuring the service life of the bearing.

[0012] Preferably, the bottom diameter of the limiting top screw matches the inner diameter of the threaded hole on the mounting seat, which facilitates the installation of the limiting top screw and ensures the seal between the limiting top screw and the mounting seat.

[0013] Preferably, a sealing layer is provided in the threaded hole, and the sealing layer is located directly below the limiting top screw. The sealing layer is filled with epoxy resin, and the lubricating oil hole is further sealed by the sealing layer to prevent leakage of the lubricating oil.

[0014] It can be seen from the above technical solutions that the advantages of the utility model are:

[0015] 1. A mounting seat and a limit screw are arranged under the bearing. The top of the limit screw is inserted into the lubricating oil hole of the outer ring of the bearing. There is no need to change the bearing structure, which avoids the processing of the bearing. On the basis of ensuring the normal operation of the equipment, the outer ring of the bearing can be fixed so that it no longer rotates relative to the crossbeam body, thereby preventing the crossbeam body from being scratched by the outer ring of the bearing and the outer ring of the bearing from being worn. At the same time, when the bearing moves along its axial direction, the mounting seat will slide along the axial direction of the bearing. The mounting seat and the limit screw will not completely limit the axial movement of the outer ring of the bearing, thereby ensuring that the working performance of the bearing will not be restricted.

[0016] 2. The limit screw is threadedly connected to the threaded hole, which is convenient for the connection between the mounting base and the limit screw and the replacement of the limit screw.

[0017] 3. The limit screw has a conical structure, and the diameter of the limit screw gradually increases from top to bottom, which not only facilitates the connection between the limit screw and the lubricating oil hole on the outer ring of the bearing, but also facilitates the sealing of the lubricating oil hole to prevent the leakage of lubricating oil, thereby ensuring the service life of the bearing. The setting of the sealing layer can further improve the sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0024] In a typical implementation of the present invention, Figure 1-Figure 2 As shown, a bearing limiting mechanism for stamping equipment is proposed, comprising: a mounting seat 2 slidably arranged on a cross beam 5, specifically, the mounting seat 2 is slidably arranged on the cross beam 5 at a position for mounting the outer ring of the bearing, the mounting seat 2 is located directly below the bearing 4 (a self-aligning bearing in this embodiment), and a limiting top screw 1 is detachably installed on the mounting seat 2, the limiting top screw 1 is vertically arranged and extends outward from the top of the mounting seat 2, and the top of the limiting top screw 1 is used to be inserted into the lubricating oil hole provided on the outer ring of the bearing 4, so as to limit the self-rotation of the outer ring of the bearing through the limiting top screw 1, and at the same time, the sliding arrangement of the mounting seat 2, the bearing 4 is axially (i.e. Figure 1 When there is some movement in the left and right directions of the viewing angle, the mounting seat 2 and the limiting top screw 1 as a whole will not completely restrict the axial movement of the outer ring of the bearing, thereby ensuring that the working performance of the bearing will not be restricted.

[0025] like Figure 1 As shown, a positioning groove 6 is processed below the position for installing the outer ring of the bearing on the crossbeam body 5 of the stamping equipment, and the positioning groove 6 extends along the axial direction of the bearing 4. The mounting seat 2 is slidably set in the positioning groove 6, so that the mounting seat 2 can slide along the positioning groove 6 to adapt to the axial movement of the bearing 4.

[0026] The shape of the positioning groove 6 matches the mounting seat 2. For example, the cross-section of the mounting seat 2 is rectangular, and the width of the positioning groove 6 matches the mounting seat 2, so that the mounting seat 2 can be guided and limited. It can be understood that the specific shape of the mounting seat 2 is not restricted too much here, and it can be rectangular, cylindrical or other shapes. The actual shape can be determined according to design requirements.

[0027] like Figure 2 As shown, the mounting seat 2 is located directly below the bearing 4, and the limit screw 1 is detachably mounted on the mounting seat 2. Specifically, a threaded hole is opened on the mounting seat 2, and the threaded hole contains an internal thread. The outer wall of the limit screw 1 is provided with an external thread. The limit screw 1 is detachably connected to the mounting seat 2 by a threaded connection.

[0028] The limit screw 1 is a conical structure, and the bottom diameter of the limit screw 1 is larger than the top thereof. The bottom diameter of the limit screw 1 matches the inner diameter of the threaded hole on the mounting seat 2 to realize the installation and positioning of the limit screw 1. The conical structure of the limit screw 1 facilitates the connection with the mounting seat 2. At the same time, since the diameter of the limit screw 1 gradually increases from top to bottom, it is not only convenient for the connection between the limit screw 1 and the lubricating oil hole on the outer ring of the bearing, but also convenient for sealing the lubricating oil hole to prevent leakage of lubricating oil, thereby ensuring the service life of the bearing 4.

[0029] A sealing layer 3 is also provided in the mounting seat 2. The sealing layer 3 is arranged in the threaded hole and is located directly below the limiting top screw 1. In this embodiment, the sealing layer 3 is filled with epoxy resin. In other embodiments, it can also be a rubber sealing pad or other structure to further seal the lubricating oil hole through the sealing layer 3 to prevent leakage of the lubricating oil.

[0030] The bearing limiting mechanism in this embodiment can fix the outer ring of the bearing so that it no longer rotates relative to the cross beam 5 while ensuring the normal operation of the equipment, thereby preventing the cross beam 5 from being scratched by the outer ring of the bearing and the outer ring of the bearing from wearing out.

[0031] Specifically, when the equipment is working, if the outer ring of the bearing has a tendency to rotate, the limiting screw 1 is pushed into the lubricating oil hole of the outer ring of the bearing, and the limiting screw 1 and the mounting seat 2 are restricted by the positioning groove 6 on the cross beam 4 and cannot move along the tangential direction of the outer ring of the bearing, thereby limiting the rotation of the outer ring of the bearing, ensuring that the outer ring of the bearing and the cross beam 5 are relatively stationary;

[0032] In addition, since the positioning groove 6 has a set length, when the bearing 4 moves along its axial direction, the mounting seat 2 will slide along the positioning groove 6, and the mounting seat 2 and the limiting top screw 1 will not completely restrict the axial movement of the outer ring of the bearing, thereby ensuring that the working performance of the bearing will not be restricted.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
