Description

Technical Field

[0001] The invention belongs to the technical field of bearing production, in particular to an automatic feeding type gear ring hydraulic press for bearing production. Background Art

[0002] A hydraulic press is a machine that uses special hydraulic oil as the working medium and a hydraulic pump as the power source. The hydraulic oil enters the oil cylinder through the hydraulic pipeline by the force of the pump. Then there are several sets of seals in the oil cylinder that cooperate with each other. The seals in different positions are different, but they all play a sealing role to prevent the hydraulic oil from leaking. Finally, the hydraulic oil circulates in the oil tank through a one-way valve to circulate the oil cylinder to do work, thereby completing a certain mechanical action as a productivity machine.

[0003] When the hydraulic press processes the gear ring used for the bearing, the curvature of the gear ring can be appropriately extruded to ensure that the gear ring is a standard circular surface. However, when the gear ring is extruded, its own extrusion force on the bottom fixed seat will inevitably increase, which will cause the base that controls the rotation of the gear ring to undergo serious deformation under the action of long-term extrusion. As a result, the curvature of the gear ring changes due to the deformation of the rotation trajectory during the self-rotation detection work, resulting in system errors, so improvements are needed. Summary of the invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve the technical problems is: an automatic feeding gear ring hydraulic press for bearing production, comprising a trimming gear ring, a load-bearing device is arranged at the bottom of the trimming gear ring, a limiting device is symmetrically arranged on the front and rear sides of the outer surface of the trimming gear ring, a pressing device is arranged on the top of the trimming gear ring, and a measuring device is symmetrically arranged on the left and right sides of the trimming gear ring;

[0005] The measuring device comprises a lubricating shaft, which will roll synchronously with the trimming gear ring through the friction force on the outer surface, and the inner wall of the lubricating shaft is symmetrically provided with horizontal connecting plates on both sides of the front and rear sides of the axis, and the end of the horizontal connecting plate away from the lubricating shaft is fixedly connected with an embedded slider, and the side of the inner wall of the embedded slider away from the horizontal connecting plate is threadedly connected with a pressure slider through an adjustment guide rod, and the embedded slider can perform fine adjustment on the height of the pressure slider, and the inner wall of the pressure slider is slidably connected with a pressure guide rod at the axis, and the bottom end of the bottom pressure guide rod is fixedly connected with a deviation meter;

[0006] The limiting device includes a support rod push plate, which is fixedly connected to a guide sliding shell at the axis of the support rod push plate, and side clamps are symmetrically arranged on the left and right sides of the inner wall of the guide sliding shell. The outer surface of the side clamp is rollingly connected with a contact ball on the side close to the trimming gear ring, and the end of the side clamp away from the support rod push plate is fixedly connected with a docking rod. After the side clamps on the front and rear sides are docked, the trimming gear ring can be restricted to rotate in a horizontal plane to prevent the trimming gear ring from tilting during rotation.

[0007] Furthermore, the load-bearing device includes a fixed base, a downward pressure load-bearing plate is fixedly connected to the axis center of the inner wall of the fixed base, auxiliary rollers are evenly arranged on the upper surface of the downward pressure load-bearing plate, side push boxes are symmetrically arranged on the left and right sides of the upper surface of the fixed base, and sliding force arms are symmetrically arranged on one side of the inner cavity of the side push box close to the downward pressure load-bearing plate, and the active roller is rotatably connected to the end of the sliding force arm away from the side push box. When the trimming gear ring is pressed downward, the active rollers on both sides will be pushed away, and the sliding force arm will be retracted into the inside of the side push box.

[0008] Furthermore, the outer surface of the active roller shaft and the outer surface of the trimming gear ring are squeezed against each other, the lower surface of the side push box is fixedly connected to the upper surface of the fixed base, and the bottom of the outer surface of the trimming gear ring is rollingly connected to the upper surface of the sliding force arm through the active roller shaft. The number of the limiting devices is two, the outer surface of the support rod push plate is fixedly connected to the wall, the outer surface of the trimming gear ring is rollingly connected to the outer surface of the contact ball, and the outer surface of the side clamp is slidingly connected to the inner wall of the guide slide shell. The axis of the inner wall of the lubrication shaft is rotationally connected to the end of the horizontal connecting plate away from the embedded slider, the outer surface of the lubrication shaft is rollingly connected to the outer surface of the trimming gear ring, the lower surface of the deviation meter is fixedly connected to the upper surface of the fixed base, and the bottom end of the pressure guide rod is slidingly connected to the inner cavity of the deviation meter.

[0009] Furthermore, the fixed base includes a storage box, and side power supply boxes are symmetrically arranged on the left and right sides of the inner wall of the storage box. The side of the side power supply box close to the load-bearing equipment is evenly provided with a transfer support plate, and the side of the side power supply box away from the load-bearing equipment is evenly provided with an external wire. The bottom of the side power supply box is fixedly connected with a height adjustment gasket. When the downward pressure bearing plate is pressed downward by the trimming gear ring, the lower surface will dock with the transfer support plate of a fixed height, and then the docking guide rod is inserted into the downward pressure bearing plate to supply power to the downward pressure bearing plate, thereby starting the downward pressure bearing plate to perform pressure measurement. The outer surface of the transfer support plate is fixedly connected to the inner cavity of the storage box through a vertical groove, the top of the transfer support plate is plugged into the lower surface of the downward pressure bearing plate through a docking guide rod, the bottom of the height adjustment gasket is fixedly connected to the inner wall of the storage box, and the end of the external wire away from the side power supply box extends to the outside of the storage box.

[0010] Furthermore, the downward pressure device includes an oil hydraulic press, a segmented pressure column is fixedly connected to the axis of the oil hydraulic press, a counterweight shell is fixedly connected to the bottom end of the segmented pressure column, a pressure-sensitive gasket is fixedly connected to the top of the inner cavity of the counterweight shell, a downward pressure inner plate is fixedly connected to the lower surface of the pressure-sensitive gasket, and inner scanning plates are symmetrically arranged on both sides of the inner wall of the counterweight shell. A groove for accommodating a lubricating shaft is provided in the middle area of ​​the counterweight shell. When the lubricating shaft rolls, monitoring work will be performed through the inner scanning plates on both sides to ensure that the inner lubricating shaft always fits the outer surface of the trimming gear ring to rotate under force. Both ends of the bottom of the downward pressure inner plate extend to the outside of the counterweight shell, the outer surface of the inner scanning plate is fixedly connected to the inner wall of the counterweight shell, the upper surface of the oil hydraulic press is fixedly connected to the ceiling, and the bottom end of the downward pressure inner plate and the outer surface of the trimming gear ring are pressed against each other.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. In order to avoid the problem of serious deformation of the active roller that controls the rotation of the dressing gear ring under long-term extrusion, the load-bearing equipment is redesigned. The active roller is contracted during the downward pressure of the gear ring, and the downward pressure load-bearing plate is used to replace the support capacity of the gear ring, thereby avoiding the problem of deformation of the active roller due to excessive downward pressure, and ensuring that the gear ring will not change its detection curvature due to deformation of the rotation trajectory during the self-rotation detection work, resulting in system errors.

[0013] 2. The device can perform self-rotation detection on the curvature of the trimming gear ring, and when a raised position is detected, the corresponding position of the trimming gear ring can be vertically pressed by the pressing device. Through slight deformation and the plasticity of the trimming gear ring itself, the curvature of the trimming gear ring can be corrected back to a normal state, thereby achieving the trimming effect. Since the lubrication shaft always fits the upper surface of the trimming gear ring and the lubrication shaft is protected in the internal position of the counterweight shell, the lubrication shaft is less likely to be disturbed by the external environment, such as wind dust suction problems, thereby ensuring the reliability of the detection results.

[0014] 3. When the dressing gear ring is rotating, the limiting devices on both sides can be used to limit and fix the dressing gear ring to ensure that the dressing gear ring will not tip over to the front and rear sides during rotation, causing itself to shake. Since the side clamps are always in contact with the outer surface of the dressing gear ring through the contact balls, the dressing gear ring will not generate a large friction resistance with the limiting devices when the dressing gear ring is rotating, resulting in the problem of being unable to rotate stably and thus getting stuck. This can ensure that the dressing gear ring itself will not suffer serious wear problems.

[0015] 4. When the dressing gear ring is performing self-rotation detection, the inner scanning plates on both sides perform real-time detection on the lubrication shaft to determine the actual stability of the lubrication shaft, and avoid the lubrication shaft from jumping due to the obstruction of particles attached to the outer surface of the dressing gear ring, which causes the measuring equipment to misjudge that the arc surface of the dressing gear ring is uneven and perform extrusion correction, thereby causing adverse changes to the curvature of the dressing gear ring.

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0025] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: an automatic feeding gear ring hydraulic press 31 for bearing production, comprising a trimming gear ring 1, a load-bearing device 2 is arranged at the bottom of the trimming gear ring 1, a limiting device 5 is symmetrically arranged on the front and rear sides of the outer surface of the trimming gear ring 1, a pressing device 3 is arranged on the top of the trimming gear ring 1, and a measuring device 4 is symmetrically arranged on the left and right sides of the trimming gear ring 1;

[0026] The measuring device 4 includes a lubricating shaft 41, which will roll synchronously with the trimming gear ring 1 due to the friction force on the outer surface. Horizontal connecting plates 42 are symmetrically arranged on the front and rear sides of the axis of the inner wall of the lubricating shaft 41. An embedded slider 43 is fixedly connected to one end of the horizontal connecting plate 42 away from the lubricating shaft 41. A pressure slider 45 is threadedly connected to the side of the inner wall of the embedded slider 43 away from the horizontal connecting plate 42 through an adjusting guide rod 44. The embedded slider 43 can perform fine adjustment of the height relative to the pressure slider 45. A pressure guide rod 46 is slidably connected to the axis of the inner wall of the pressure slider 45, and a deviation meter 47 is fixedly connected to the bottom end of the bottom pressure guide rod 46.

[0027] The limiting device 5 includes a support rod push plate 51, a guide sliding shell 52 is fixedly connected to the axis of the support rod push plate 51, side clamps 53 are symmetrically arranged on the left and right sides of the inner wall of the guide sliding shell 52, a contact ball 54 is rollingly connected to the side of the outer surface of the side clamp 53 close to the trimming gear ring 1, and a docking rod 55 is fixedly connected to the end of the side clamp 53 away from the support rod push plate 51. After the side clamps 53 on the front and rear sides are docked, the trimming gear ring 1 can be restricted to rotate in a horizontal plane to prevent the trimming gear ring 1 from tilting during rotation.

[0028] The load-bearing device 2 includes a fixed base 21, a downward pressure load-bearing plate 26 is fixedly connected to the axis center of the inner wall of the fixed base 21, and auxiliary rollers 25 are evenly arranged on the upper surface of the downward pressure load-bearing plate 26. Side push boxes 22 are symmetrically arranged on the left and right sides of the upper surface of the fixed base 21, and sliding force arms 23 are symmetrically arranged on one side of the inner cavity of the side push box 22 close to the downward pressure load-bearing plate 26. The end of the sliding force arm 23 away from the side push box 22 is rotatably connected to the active roller 24. When the trimming gear ring 1 is pressed downward, the active rollers 24 on both sides will be pushed away, and the sliding force arm 23 will be retracted into the inside of the side push box 22.

[0029] The outer surface of the active roller 24 and the outer surface of the trimming gear ring 1 are mutually squeezed, the lower surface of the side push box 22 is fixedly connected to the upper surface of the fixed base 21, and the bottom of the outer surface of the trimming gear ring 1 is rollingly connected to the upper surface of the sliding arm 23 through the active roller 24. There are two limit devices 5, the outer surface of the support rod push plate 51 is fixedly connected to the wall, the outer surface of the trimming gear ring 1 is rollingly connected to the outer surface of the contact ball 54, and the outer surface of the side clamping plate 53 is slidingly connected to the inner wall of the guide sliding shell 52. The axis of the inner wall of the lubrication shaft 41 is rotationally connected to the end of the horizontal connecting plate 42 away from the embedded slider 43, the outer surface of the lubrication shaft 41 is rollingly connected to the outer surface of the trimming gear ring 1, the lower surface of the deviation meter 47 is fixedly connected to the upper surface of the fixed base 21, and the bottom end of the pressure guide rod 46 is slidingly connected to the inner cavity of the deviation meter 47.

[0030] When using the device to perform trimming and inspection work on the gear ring, the trimming gear ring 1 is placed on the load-bearing device 2, and then the limiting devices 5 on the front and rear sides clamp the middle position of the trimming gear ring 1, and limit it without affecting the self-rotation of the trimming gear ring 1 to ensure that the trimming gear ring 1 can rotate smoothly, and then adjust the height of the embedded sliders 43 on both sides to make the heights of the embedded sliders 43 on both sides the same, to ensure that the lubrication shaft 41 can be close to the top position of the outer surface of the trimming gear ring 1, and then work can be carried out.

[0031] The active rollers 24 on both sides drive the outer surface of the trimming gear ring 1 to rotate by rolling friction. At this time, the trimming gear ring 1 rotates relative to the auxiliary roller 25. When the trimming gear ring 1 rotates, if there is a convex position of the arc, the area here will push the lubrication shaft 41 upward when passing through the lubrication shaft 41, and then drive the pressure sliders 45 on both sides to slide vertically relative to the pressure guide rod 46 through the lubrication shaft 41 and the horizontal connecting plate 42. Since the deviation meter 47 is relatively sensitive, the deviation meter 47 will judge the curvature change position of the trimming gear ring 1 according to the change in pressure, and then the active roller 24 will rotate the area here to the position just above, and press the trimming gear ring 1 by pressing down, so that the convex position of the trimming gear ring 1 is pressed down and trimmed.

[0032] When the trimming gear ring 1 is pressed down, the active roller shafts 24 on both sides will be affected by the downward pressure component force, pushing the sliding force arm 23 to slide toward the inside of the side push box 22, and then gradually separate from the trimming gear ring 1, and the downward pressure bearing plate 26 directly below will continue to slide downward, and then the downward pressure bearing plate 26 reaches a static position and no longer moves, and together with the downward pressure device 3, presses the trimming gear ring 1 into a standard arc surface, and then the downward pressure device 3 stops pressing, and the downward pressure bearing plate 26 bounces up and resets, and the active roller shafts 24 on both sides also continue to contact the bottom position of the trimming gear ring 1 as the sliding force arm 23 pops out, thereby continuing to push the trimming gear ring 1 to perform self-rotation scanning until the entire trimming gear ring 1 is corrected.

[0033] Example 2, please refer to Figure 1-Figure 7 The present invention provides a technical solution: on the basis of Example 1, the fixed base 21 includes a accommodating box 211, and side power supply boxes 212 are symmetrically arranged on the left and right sides of the inner wall of the accommodating box 211, and the side of the side power supply box 212 close to the load-bearing equipment 2 is evenly provided with a transfer support plate 215, and the side of the side power supply box 212 away from the load-bearing equipment 2 is evenly provided with an external wire 214, and the bottom of the side power supply box 212 is fixedly connected with a height adjustment gasket 213. When the downward pressure bearing plate 26 is pressed downward by the trimming gear ring 1, the lower surface will dock with the transfer support plate 215 of a fixed height, and then the docking guide rod 216 is inserted into the downward pressure bearing plate 26 to supply power to the downward pressure bearing plate 26, thereby starting the downward pressure bearing plate 26 to perform pressure measurement. The outer surface of the adapter support plate 215 is fixedly connected to the inner cavity of the storage box 211 through a vertical groove, the top of the adapter support plate 215 is plugged into the lower surface of the downward pressure bearing plate 26 through a docking guide rod 216, the bottom of the height adjustment gasket 213 is fixedly connected to the inner wall of the storage box 211, and the external wire 214 extends from one end away from the side power supply box 212 to the outside of the storage box 211.

[0034] The pressing device 3 includes an oil press 31, a segmented pressure column 32 is fixedly connected at the axis of the oil press 31, a counterweight shell 33 is fixedly connected at the bottom end of the segmented pressure column 32, a pressure-sensitive gasket 35 is fixedly connected to the top of the inner cavity of the counterweight shell 33, a pressing inner plate 34 is fixedly connected to the lower surface of the pressure-sensitive gasket 35, and an inner scanning plate 36 is symmetrically arranged on both sides of the inner wall of the counterweight shell 33. A groove for accommodating the lubricating shaft 41 is opened in the middle area of ​​the counterweight shell 33. When the lubricating shaft 41 rolls, it will be detected by the inner scanning plates 36 on both sides to ensure that the inner lubricating shaft 41 always fits the outer surface of the trimming gear ring 1 and rotates under force. Both ends of the bottom of the pressing inner plate 34 extend to the outside of the counterweight shell 33, the outer surface of the inner scanning plate 36 is fixedly connected to the inner wall of the counterweight shell 33, the upper surface of the oil press 31 is fixedly connected to the ceiling, and the bottom end of the pressing inner plate 34 and the outer surface of the trimming gear ring 1 are pressed against each other.

[0035] When the downward pressure load-bearing plate 26 is squeezed downward, it will dock with the adapter support plate 215. At this time, the downward pressure load-bearing plate 26 will no longer descend, and the docking guide rod 216 will dock with the internal power port of the downward pressure load-bearing plate 26, so that the downward pressure load-bearing plate 26 can detect the actual squeezing force it is subjected to, thereby controlling the pressure applied by the downward pressure device 3. The height-adjusting gaskets 213 of different heights can be replaced according to the actual deformation capacity of the trimming gear ring 1, so that the adapter support plate 215 can clamp the downward pressure load-bearing plate 26 at an appropriate height.

[0036] The hydraulic press 31 pushes the counterweight shell 33 downward by means of the pressurized segmented pressure column 32. At this time, the thick downward pressure inner plates 34 on both sides of the counterweight shell 33 replace the counterweight shell 33 body to apply downward pressure to the outer surface of the trimming gear ring 1. At this time, the counterweight shell 33 slides downward relative to the lubrication shaft 41, and the trimming gear ring 1 is pressed down, and then the extrusion deformation work is performed. When the trimming gear ring 1 performs self-rotation detection, the inner scanning plates 36 on both sides perform real-time detection of the lubrication shaft 41, so as to judge the actual stability of the lubrication shaft 41, and avoid the phenomenon that the lubrication shaft 41 is blocked by particles attached to the outer surface of the trimming gear ring 1 and then jumps, causing the measuring equipment 4 to misjudge that the arc surface of the trimming gear ring 1 is uneven and thus perform extrusion correction work, thereby causing adverse changes to the curvature of the trimming gear ring 1.

[0037] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
