Description

Technical Field

[0001] The present invention relates to the technical field of oil seal pressing, and in particular to oil seal pressing equipment for new energy vehicles. Background Art

[0002] Oil seal is the customary name for general seals. Simply put, it is a seal for lubricating oil. It is a mechanical component used to seal grease (oil is the most common liquid substance in the transmission system, and also refers to general liquid substances). It isolates the parts that need lubrication from the output parts in the transmission components to prevent the lubricating oil from leaking. In the new energy vehicle industry, a large number of oil seals are used for the assembly of related components, such as bearing cover oil seals or motor oil seals of new energy vehicles.

[0003] When assembling the oil seal, the prior art generally assembles the oil seal by direct pressing. For example, the invention patent with the authorization announcement number CN116728044B discloses an oil seal assembly device, which presses the oil seal down by an elastic pressing device for multiple times, and elastic deformation occurs during the pressing process. Then, the elastic pressing device is struck by a knocking device to cause vibration, so that the oil seal is vibrated and gradually corrects its posture. The oil seal is assembled by the pressure of the elastic pressing device, which avoids the problem of damage caused by direct pressing due to the angle between the center line of the oil seal and the center line of the workpiece during assembly. However, when the oil seal is press-fitted in the above manner, the oil seal is first placed directly at the corresponding position, and then the oil seal is directly pressed down by an elastic pressing device, and then the posture of the oil seal is corrected by vibration, that is, the oil seal is pressed down first and the posture of the oil seal is corrected later. Since the oil seal is inclined compared to the assembly end face when it is initially placed, that is, at this time, there is an angle between the oil seal and the press-fitting surface on the workpiece, which makes the outer circular edge of the oil seal inclined or partially protruding. Therefore, the outer circular edge surface of the oil seal will be squeezed with the workpiece during the posture correction process, which will cause the oil seal to be damaged during the correction process, affecting the sealing effect after the workpiece is assembled with the oil seal.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figures 1 to 5 As shown, the present invention provides an oil seal pressing device for new energy vehicles, including a support plate 1, a fixing device 2 for fixing a workpiece is arranged at the middle position of the support plate 1, a linear moving device 3 located on one side of the fixing device 2 is arranged on the support plate 1, a telescopic device 4 is arranged on the linear moving device 3, and the telescopic direction of the telescopic device 4 is perpendicular to the moving direction of the linear moving device 3 and parallel to the length direction of the workpiece, a connecting seat 5 is arranged at the end of the telescopic device 4, a connecting column 6 is vertically arranged on the connecting seat 5, a rotating diffusion device 7 is arranged at the end of the connecting column 6, a bearing device 8, an adsorption limiting device 9 and a reset device 10 are arranged on the peripheral side of the connecting column 6, and the bearing device 8 is slidably arranged on the peripheral side of the connecting column 6 and can be automatically reset, and the adsorption limiting device 9 and the reset device 10 can both move along the axial direction of the connecting column 6.

[0028] Among them, the rotating diffusion device 7 is used to control the radial sliding of the carrying device 8 along the connecting column 6, the carrying device 8 is used to carry the oil seal and adapt to the pressing surface of the workpiece before carrying the oil seal, the adsorption limiting device 9 is used to temporarily adsorb and fix the oil seal before the carrying device 8 carries the oil seal, and the resetting device 10 is used to reset the carrying device 8.

[0029] When the present invention is actually applied, a workpiece (such as a bearing cover) is placed on the fixing device 2 for fixing, so that one end of the workpiece faces the direction of the telescopic device 4 .

[0030] After the workpiece is fixed, the oil seal is passed through the connecting column 6, and the oil seal is fixed by the adsorption limiting device 9, and then the position of the telescopic device 4 is adjusted in a direction perpendicular to the axis of the workpiece by the linear moving device 3, so that the oil seal is aligned with the workpiece, and then the telescopic device 4 drives the oil seal to gradually approach the workpiece, and the rotating diffusion device 7 drives the bearing device 8 to slide out to carry the oil seal. When the telescopic device 4 is extended, the bearing device 8 first abuts against the press-fitting surface of the workpiece (that is, the end face of the press-fitted oil seal), so that the bearing device 8 fits the press-fitting surface of the workpiece, and then the adsorption limiting device 9 controls the oil seal to move to the bearing device 8 for fixing. At this time, the oil seal is fitted and fixed with the bearing device 8, that is, parallel and concentric with the end face of the workpiece. After the oil seal is fixed by the bearing device 8, the adsorption limiting device 9 is reset to move away from the bearing device 8, and finally the rotating diffusion device 7 is reset, so that the bearing device 8 is automatically reset, so that the oil seal is accurately placed on the press-fitting surface of the workpiece after correction, and the oil seal is pressed down by the adsorption limiting device 9 to complete the press-fitting of the entire oil seal, thereby ensuring the press-fitting effect and sealing effect of the oil seal.

[0031] The rotary diffusion device 7 includes a rotating device 701 arranged at the end of the connecting column 6, and a mounting groove 702 for mounting the rotating device 701 is opened at the end of the connecting column 6. The output shaft of the rotating device 701 is fixedly connected to a rotating seat 703 through a connecting shaft. A plurality of arc-shaped pressure plates 704 are evenly arranged on the circumferential side of the rotating seat 703, and the plurality of arc-shaped pressure plates 704 are used to squeeze the supporting device 8 to move radially along the connecting column 6.

[0032] The rotating device 701 drives the connecting shaft to drive the rotating seat 703 to rotate, so that the multiple arc-shaped pressure plates 704 rotate around the axis of the connecting shaft. The outer arc surface of the arc-shaped pressure plate 704 squeezes the supporting device 8 to slide radially toward the outside of the connecting column 6, so that the supporting device 8 extends to the outside of the end surface of the connecting column 6 to support the oil seal.

[0033] When the arc-shaped pressing plate 704 rotates to be out of contact with the carrying device 8, the carrying device 8 automatically resets to allow the oil seal to be placed on the press-fitting surface of the workpiece for press-fitting.

[0034] Furthermore, the fixing device 2 can adjust the distance between it and the supporting plate 1 to accommodate workpieces of different sizes.

[0035] The carrying device 8 includes a plurality of strip plates 801 slidably connected to the connecting column 6, a plurality of slide grooves 802 communicating with the inside of the mounting groove 702 are evenly provided at the end of the connecting column 6, and the plurality of slide grooves 802 extend along the radial direction of the connecting column 6 to communicate with the peripheral outer wall of the connecting column 6, each strip plate 801 is slidably connected in the corresponding slide groove 802, a limiting groove 803 is provided on the side of each strip plate 801 away from the center line of the connecting column 6, a carrying plate 804 for carrying an oil seal is slidably connected in each limiting groove 803, and each carrying plate 804 is connected to the corresponding limiting groove 803 by interference fit, each carrying plate 804 is provided with a plurality of air holes 808, and the plurality of air holes 808 are commonly connected to the first air pump, and an elastic rope 805 is provided on the side of each strip plate 801 facing the center line of the connecting column 6, and the plurality of elastic ropes 805 are commonly connected to an annular fixing plate 806 connected to the inner wall of the mounting groove 702.

[0036] When the arc pressure plate 704 is driven to rotate by the rotating device 701, the outer arc surface of the arc pressure plate 704 first abuts against the corresponding strip plate 801, and squeezes the corresponding strip plate 801 to slide along the slide groove 802 toward the outside of the connecting column 6, so that the supporting plate 804 extends to the outside of the end surface of the connecting column 6 (the distance between the supporting plate 804 and the center of the connecting column 6 is greater than the diameter of the connecting column 6), and after the arc pressure plate 704 is out of contact with the strip plate 801, the strip plate 801 is automatically reset under the elastic force of the elastic rope 805, so that the supporting plate 804 can be separated from the oil seal and release the oil seal to the pressing surface of the workpiece, and the annular fixing plate 806 is used to fix the end of the elastic rope 805.

[0037] When the supporting plate 804 contacts the end face of the workpiece, the multiple supporting plates 804 slide along the corresponding limiting grooves 803 under the pressure of the pressing surface of the workpiece, so as to correct the supporting surface composed of the multiple supporting plates 804, and because there is an interference fit between the supporting plate 804 and the limiting grooves 803, the supporting plate 804 will not move without external force after sliding in the limiting grooves 803, so that the oil seal is placed on the multiple supporting plates 804. Parallel and concentric with the end face of the workpiece, the pressing effect of the oil seal is ensured, and after the oil seal is placed on the multiple supporting plates 804, the first air pump absorbs and fixes the oil seal through the multiple air holes 808 to ensure the stability of the oil seal before placement.

[0038] A magnetic plate 807 is provided at the inner bottom of each slide groove 802 , and a metal plate for magnetically attracting the magnetic plate 807 is provided on each strip plate 801 , and the magnetic plate 807 is located between the strip plate 801 and the mounting groove 702 .

[0039] After the strip plate 801 is reset, the magnetic plate 807 attracts the metal plate through magnetic force, thereby preventing the strip plate 801 from sliding freely in the slide groove 802 and interfering with the press-fitting of the oil seal.

[0040] The strip plate 801 extends along the axial direction of the connecting column 6 to the outside of the connecting column 6 .

[0041] The area between the plurality of strip plates 801 is made hollow to avoid interference between the strip plates 801 and other structures.

[0042] The adsorption limiting device 9 includes a first linear drive device 901 arranged on the outer wall of the connecting column 6, and an annular movable plate 902 is arranged on the first linear drive device 901, and the annular movable plate 902 is slidably sleeved on the surface of the connecting column 6, and a plurality of adsorption holes 903 for adsorbing oil seals are arranged on the side of the annular movable plate 902 away from the telescopic device 4, and the plurality of adsorption holes 903 are commonly connected to a second air pump through an air pipe.

[0043] The oil seal is sleeved outside the connecting column 6 and abuts against the annular movable plate 902. The second air pump absorbs and fixes the oil seal through multiple adsorption holes 903. After the position correction of the multiple bearing plates 804 is completed, the first linear drive device 901 drives the annular movable plate 902 to move along the axial direction of the connecting column 6 until the oil seal contacts the bearing plate 804. At this time, after the corresponding sensing element detects that the oil seal contacts the bearing plate 804, the first linear drive device 901 and the second air pump both stop working. At the same time, the first air pump absorbs and fixes the oil seal on the bearing surface composed of the multiple bearing plates 804 through multiple air holes 808. Then, the rotary diffusion device 7 is reset, so that the arc pressure plate 704 is out of contact with the corresponding strip plate 801, so that the strip plate 801 drives the corresponding bearing plate 804 to reset under the traction of the elastic rope 805, so that the multiple bearing plates 804 are out of contact with the oil seal at the same time, and the oil seal falls into the pressing surface of the workpiece under the action of gravity. Then, the first linear drive device 901 drives the annular movable plate 902 to press down the oil seal to complete the pressing of the oil seal.

[0044] Furthermore, the thickness of the bearing plate 804 should be as small as possible to reduce the height of the oil seal falling and ensure that the oil seal is parallel to the press-fitting surface of the workpiece.

[0045] An elastic sponge layer is provided on the surface of the annular movable plate 902 which faces away from the telescopic device 4 , and the elastic sponge layer can allow airflow to pass through.

[0046] The elastic sponge layer provides a buffer to prevent the annular movable plate 902 from causing damage to the oil seal.

[0047] The reset device 10 includes a second linear drive device 101 arranged on the outer wall of the connecting column 6, and an annular reset plate 102 is arranged on the second linear drive device 101. A plurality of strip reset plates 103 corresponding to the position of the supporting plate 804 are arranged on the side of the annular reset plate 102 away from the telescopic device 4, and a plurality of through grooves 104 for the strip reset plates 103 to pass through are opened on the annular movable plate 902.

[0048] After the oil seal is pressed, the adsorption limiting device 9 is reset. At this time, the rotating diffusion device 7 squeezes the multiple strip plates 801 to slide outside the connecting column 6, so that the supporting plate 804 extends to the outside of the end face of the connecting column 6, and then the second linear drive device 101 drives the annular reset plate 102 to drive the multiple strip reset plates 103 to pass through the corresponding through grooves 104, so that the multiple strip reset plates 103 squeeze the corresponding supporting plates 804 and move them to the inner side wall of the limiting groove 803, so as to press the next oil seal.

[0049] In this embodiment, the linear moving device 3, the first linear driving device 901 and the second linear driving device 101 are all prior art, such as a motor-driven screw, etc., the telescopic device 4 is also prior art, such as an electric push rod, etc., the rotating device 701 is also prior art, such as direct motor drive, or a motor driven by a reducer, etc., the fixing device 2 is also prior art, for example, by squeezing the workpiece from both sides of the workpiece to fix it, and adjusting the position of the two arc-shaped fixing plates by an electric push rod, etc., and the technical principles of the above devices will not be elaborated in detail.

[0050] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
