Positioning device and positioning method for machining thrust spherical roller bearing

Abstract

The present invention discloses a positioning device and a positioning method for machining a thrust spherical roller bearing, which belong to the technical field of bearing machining. By contacting and locking an outer positioning column with the inner wall of a bearing component, the bearing component can be positioned and the center of the bearing component can be calibrated, that is, the bearing component can be positioned from the inside. When switching the position of the bearing component positioning, the electric hydraulic rod contracts and pulls the pin. Similarly, the positioning inner column is away from the inner wall of the bearing component, so that the bearing component can be locked by the positioning outer column. The bearing component is positioned by the positioning outer column and the positioning inner column, and the bearing component is positioned at multiple points by a columnar structure to ensure positioning stability. Therefore, the positioning device can freely switch between the methods of positioning from the inside and outside of the bearing component to reduce the positioning deviation caused by frequent adjustment of the position of the bearing component, improve the convenience of positioning operation and the machining accuracy of the bearing component.

Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, and in particular to a positioning device and a positioning method for processing a thrust spherical roller bearing. Background Art

[0002] Thrust spherical roller bearings are a type of bearing that can bear both axial and radial loads, have an automatic self-aligning function, and can adapt to the non-concentricity or deflection of the shaft or bearing seat. The rollers of this type of bearing are spherical, so they can automatically adjust when subjected to load and are insensitive to coaxiality and shaft deflection.

[0003] In the processing of thrust spherical roller bearings, positioning is a key step to ensure the precise processing of bearing components. At present, arc-shaped clamps are usually used to clamp bearing components. Due to the different curvatures of bearing components of different specifications, they are prone to movement and shaking due to the vibration force of processing when locked for processing; when processing thrust spherical roller bearing components, since the clamping surface of the bearing component is covered by the clamping plate, it is necessary to remove the bearing component from the positioning device, adjust the position of the clamping surface so that it is exposed to the outside, and then perform the locking process. The operation is complicated and the work intensity is high. At the same time, in the process of adjusting the position of the bearing component, the positioning center of the bearing component is prone to deviation, which in turn affects the processing accuracy of the bearing component.

[0004] Based on this, the present invention designs a positioning device and a positioning method for machining a thrust spherical roller bearing to solve the above problems. Summary of the invention

The outside of the filter box is connected to five exhaust ducts, and the exhaust ducts are installed through the support column.

[0015] A positioning method for a positioning device for machining a thrust spherical roller bearing, the positioning method comprising the following steps:

[0016] The thrust spherical roller bearing component is placed on the processing table. When positioning the bearing component from the inside, the electric hydraulic rod is controlled to work, so that the electric hydraulic rod is extended and drives the pin to deflect, and the pin pulls the deflection disk to rotate. During the rotation of the deflection disk, the slide column in the locking assembly can slide in the arc slideway on the deflection disk. The slide column is restricted by the arc slideway so that it can drive the slide seat to move, so that the five slide seats respectively drive the five positioning outer columns and the five positioning inner columns away from the center position of the processing table, so that the positioning outer columns can be away from the outer wall of the bearing component, thereby reserving space for processing. At the same time, the five positioning outer columns contact the inner wall of the bearing component and lock it, so that the purpose of positioning the bearing component is achieved and the center of the bearing component can be calibrated. At this time, the electric hydraulic rod stops extending, and the bearing component can be positioned from the inside;

[0017] When positioning the bearing component from the outside, the electric hydraulic rod is controlled to contract and pull the pin, so that the pin can drive the deflection plate to rotate. During the rotation of the deflection plate, the slide column can slide in the arc slideway, so that the slide column drives the positioning outer column and the positioning inner column to move. During this process, the five positioning inner columns are close to each other and away from the inner wall of the bearing component, so that the clamping surface of the inner wall of the bearing component is exposed to the outside, thereby reserving space for processing the inside of the bearing component. The five positioning outer columns are close to each other and contact with the outer wall of the bearing component, so that the bearing component can be locked by the positioning outer column, and the bearing component can be positioned from the outside;

[0018] During the processing of bearing components, debris and dust will be generated. Some of the debris will fall into the support column through the inner sliding hole and can be collected through the chip cleaning holes on the outside of the support column. Some of the debris will leave the processing table through the outer sliding hole. When the debris falls into the chute, as the slide column moves in the chute, the debris can be pushed out through the leakage hole, and the dust-containing air will float upward. By controlling the operation of the fan, the suction nozzle in the dust suction pipe can absorb the dust-containing gas. The dust-containing gas enters the filter box through the air duct and the fan. The filter box then separates the impurities, and the treated air is discharged from the support column through the exhaust pipe.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention controls the operation of the electric hydraulic rod to extend the electric hydraulic rod and drive the pin to deflect, and the pin pulls the deflection disk to rotate. During the rotation of the deflection disk, the slide column can slide in the arc slideway, so that the slide seat drives the positioning outer column and the positioning inner column to move away from each other, so that the positioning outer column can move away from the outer wall of the bearing component, thereby reserving space for processing. At the same time, the five positioning outer columns contact and lock the inner wall of the bearing component, so that the bearing component can be calibrated at the center while achieving the purpose of positioning the bearing component, that is, the bearing component can be positioned from the inside. When switching the position of the bearing component positioning, the electric hydraulic rod contracts and pulls the pin, so that the pin can drive the deflection disk to rotate. During the rotation of the deflection disk, the slide column drives the positioning outer column and the positioning inner column to move. During the movement, the five positioning inner columns are close to each other and away from the inner wall of the bearing component, so that the clamping surface of the inner wall of the bearing component is exposed, thereby reserving space for internal processing of the bearing component, and the five positioning outer columns are close to each other and in contact with the outer wall of the bearing component, so that the bearing component can be locked by the positioning outer columns, that is, the bearing component can be positioned from the outside, and the bearing component is positioned by the positioning outer columns and the positioning inner columns, abandoning the traditional use of arc-shaped clamping plates to clamp it, and the bearing component is positioned at multiple points through a columnar structure to ensure positioning stability. Therefore, the positioning device can freely switch between the positioning methods from the inside and outside of the bearing component to reduce the positioning deviation caused by frequent adjustment of the position of the bearing component, and improve the convenience of positioning operation and the processing accuracy of the bearing component.

[0021] 2. When the bearing component is processed by the present invention, some debris falls into the support column through the inner sliding hole or falls through the outer sliding hole. The chip cleaning hole opened on the outside of the support column facilitates the collection of debris and prevents the debris from falling into the support column and being difficult to clean. Some debris will leave the processing table through the outer sliding hole. When the debris falls into the slide groove, as the slide column moves in the slide groove, the debris can be pushed out through the leakage hole, further improving the convenience of chip collection operation. The dust-containing air floats upward. After the fan is working, the suction nozzle in the dust suction pipe can absorb the dust-containing gas. The dust-containing gas enters the filter box through the air duct and the fan. The filter box can separate impurities, thereby optimizing the processing environment. By operating the filter box from the bottom of the mounting base, it can be removed from the support column to facilitate cleaning of the filter box. BRIEF DESCRIPTION OF THE DRAWINGS

The extraction component 11 is installed inside the support column 1, and the bottom port of the extraction component 11 passes through the support column 1.

[0037] During operation, the locking assembly 8 is limited by the slide groove 9, the inner slide hole 6 and the outer slide hole 7, so that the locking assembly 8 always keeps horizontal movement, thereby improving the stability of the locking assembly 8 in positioning the bearing component.

[0038] As a further solution of the present invention, a leakage hole 12 is opened at the bottom of the inner wall of the chute 9 , and a plurality of chip cleaning holes 13 are opened on the outer wall of the support column 1 .

[0039] During operation, some debris will fall into the support column 1 through the inner sliding hole 6 or fall through the outer sliding hole 7. The chip cleaning hole 13 opened on the outside of the support column 1 facilitates the collection of debris; some debris will leave the processing table 2 through the outer sliding hole 7. When the debris falls into the chute 9, as the sliding column 802 moves in the chute 9, the debris can be pushed out through the leakage hole 12.

[0041] During operation, the mounting base 16 can be fixed at a specified position through the mounting hole, thereby facilitating adjustment of the mounting position of the mounting base 16, because multiple support legs 15 are equidistantly arranged on the mounting base 16 and the support column 1, and the mounting base 16 can also be counterweighted, thereby improving the stability of the positioning device.

The two sides of the top of the slide 801 are respectively fixedly connected to a positioning outer column 803 and a positioning inner column 804. Several positioning inner columns 804 are overlapped on one side close to each other, and the positioning inner column 804 slides through the inner sliding hole 6, and the positioning outer column 803 slides through the outer sliding hole 7.

[0045] During operation, the bearing component is clamped by positioning the outer column 803 and the inner column 804, and the columnar structure performs multi-point positioning on the bearing component to ensure positioning stability.

[0046] As a further solution of the present invention, the adsorption component 10 includes a dust suction pipe 101, and a plurality of suction nozzles 103 are installed on the inner wall of the dust suction pipe 101. The bottom of the dust suction pipe 101 is fixedly connected to a fixed block 102, and the fixed block 102 is fixed to the outer wall of the processing table 2. The outer wall of the dust suction pipe 101 is connected to an air duct 104, and the air duct 104 passes through the support column 1 and is connected to the extraction component 11. The angle between two adjacent dust suction pipes 101 is one hundred and twenty degrees.

[0047] During operation, since the air containing dust floats upward, the suction nozzle 103 in the dust suction pipe 101 can absorb the dust-containing gas after the fan 111 works, preventing the dust gas from being absorbed by personnel, thereby optimizing the processing environment.

[0050] A positioning method for a positioning device for machining a thrust spherical roller bearing, the positioning method comprising the following steps:

[0051] The thrust spherical roller bearing component is placed on the processing table 2. When positioning the bearing component from the inside, the electric hydraulic rod 4 is controlled to work, so that the electric hydraulic rod 4 is extended and drives the pin 5 to deflect, and the pin 5 pulls the deflection plate 301 to rotate. During the rotation of the deflection plate 301, the slide column 802 in the locking assembly 8 can slide in the arc slideway 303 on the deflection plate 301. The slide column 802 is restricted by the arc slideway 303 so that it can drive the slide seat 801 to move, so that the five slide seats 801 respectively drive the five positioning outer columns 803 and the five positioning inner columns 804 away from the center position of the processing table 2, so that the positioning outer column 803 can be away from the outer wall of the bearing component, thereby reserving space for processing. At the same time, the five positioning outer columns 803 contact the inner wall of the bearing component and lock it, so as to achieve the purpose of positioning the bearing component and calibrate the center of the bearing component. At this time, the electric hydraulic rod 4 stops extending, and the bearing component can be positioned from the inside.

[0052] When positioning the bearing component from the outside, the electric hydraulic rod 4 is controlled to contract and pull the pin 5, so that the pin 5 can drive the deflection plate 301 to rotate. During the rotation of the deflection plate 301, the slide column 802 can slide in the arc slideway 303, so that the slide column 802 drives the positioning outer column 803 and the positioning inner column 804 to move. During this process, the five positioning inner columns 804 are close to each other and away from the inner wall of the bearing component, so that the clamping surface of the inner wall of the bearing component is exposed to the outside, thereby reserving space for processing the inside of the bearing component. The five positioning outer columns 803 are close to each other and contact with the outer wall of the bearing component, so that the bearing component can be locked by the positioning outer column 803, and the bearing component can be positioned from the outside;

[0053] During the processing of the bearing components, debris and dust will be generated. Some of the debris will fall into the support column 1 through the inner slide hole 6, and the debris can be collected through the chip cleaning hole 13 opened on the outside of the support column 1. Some of the debris will leave the processing table 2 through the outer slide hole 7. When the debris falls into the slide groove 9, as the slide column 802 moves in the slide groove 9, the debris can be pushed out through the leakage hole 12, and the dust-containing air will float upward. By controlling the operation of the fan 111, the suction nozzle 103 in the dust suction pipe 101 can absorb the dust-containing gas. The dust-containing gas enters the filter box 112 through the air duct 104 and the fan 111. The filter box 112 then separates the impurities, and the treated air is discharged from the support column 1 through the exhaust pipe 113.

Part of the debris falls into the support column (1) through the inner sliding hole (6) and is collected through the chip cleaning hole (13) provided on the outside of the support column (1). Part of the debris is separated from the processing table (2) through the outer sliding hole (7). When the debris falls into the slide groove (9), as the slide column (802) moves in the slide groove (9), the debris can be pushed out through the leakage hole (12), and the air containing dust floats upward. By controlling the operation of the fan (111), the suction nozzle (103) in the dust suction pipe (101) can absorb the dust-containing gas. The dust-containing gas enters the filter box (112) through the air guide pipe (104) and the fan (111). The filter box (112) then separates the impurities, and the treated air is discharged from the support column (1) through the exhaust pipe (113).
