Description

Technical Field

[0001] The invention relates to a bearing bush assembly processing technology and tooling. Background Art

[0002] Traditional bearings are set in half, which requires an additional marking process. During assembly, the assembler needs to check twice to prevent pairing misalignment. Traditional cutting forms a straight line. Although the process is simple, because it is on a straight line, in actual work, due to the similar structures on both sides and the symmetrical gaps, there are technical problems such as high noise and vibration. Due to the existence of internal stress, large deformation occurs during cutting, and a large elastic force is generated for thin-walled bearings.

[0115] The bearing bush assembly processing process of this embodiment is performed by using the above-mentioned tooling;

[0116] Step 1: performing wire cutting on the bearing bush 1 to form a half bush 2;

[0117] Step 2: blunting the sharp corners of the half tile 2 and removing burrs.

[0118] Follow these steps;

[0119] S1.1, at the loading station, first, place the bearing 1 between half-support A47 and half-support B48. The bearing 1 presses down the elastic upper push rod 54 by gravity.

[0120] Then, the pressing plate fingers 53 are controlled by rotating the telescopic arm portion 52 so that the side baffle 50 presses one side of the bearing pad 1 and the pressing plate fingers 53 press the other side of the bearing pad 1;

[0121] S1.2, first, the longitudinal push rod 45 pushes the bearing bush 1 toward the wire cutting station or the milling station; then, the oblique groove B10 and the oblique groove A9 are machined respectively; secondly, the intermediate groove 8 is machined;

[0122] S1.3, after processing, the longitudinal push rod portion 45 returns the bearing bushing 1 to the separation station;

[0123] S1.4, first, release the pressure plate finger 53 on the side of the front finger 41; first, push the front finger 41 forward through the half tile 2 on one side;

[0124] Then, the half tile 2 enters the channel A34 and falls out;

[0125] Secondly, when the curved portion of the half-tile 2 faces the U-shaped support 36, the curved portion of the half-tile 2 contacts the U-shaped support 36, achieving a high probability of flipping. When the curved portion of the half-tile 2 faces the U-shaped support 36, the curved portion of the half-tile 2 does not contact the U-shaped support 36 and falls directly.

[0126] S1.5, the elastic upper push rod 54 extends obliquely upward to catch the bottom of the half tile 2;

[0127] S1.6, first, the longitudinal push rod part 45 drives the bearing bushing 1 to continue moving; then, the pressure plate finger 53 on the side of the rear finger 42 is released, and the rear finger 42 is pushed forward through the half bushing 2 on one side; secondly, the half bushing 2 enters the channel B37 and falls out.

[0128] The bearing bushing 1 comprises half bushings 2 which are matched to achieve fixed installation in half.

[0129] For the convenience of description, the half-tile 2 has a side end portion 5;

[0130] The side end portion 5 has an oblique opening 6 and a protrusion 7 arranged on the same side;

[0131] The bearing is fixed by interference fit, and can also be fixed by top screws, side fixation or other methods.

[0132] The oblique opening 6 of one half tile 2 and the protrusion 7 of the other half tile 2 are engaged with each other to form an oblique groove B10 and an oblique groove A9;

[0133] A circumferentially arranged intermediate groove 8 is connected between the oblique groove B10 and the oblique groove A9, thereby achieving an interference fit while avoiding the slots being cut on a line. It can be machined by wire cutting or milling.

[0134] Marked lines are provided on the middle slot 8, which use different lines to facilitate later matching.

[0135] An oil groove 3 and a process outer groove 4 are respectively provided on the inner and outer sides of the middle part of the bearing bush 1 .

[0136] The bearing bush 1 is provided with an oil filling hole 14 communicating with the oil groove portion 3 and the process outer groove 4 .

[0137] As a beneficial effect, the frame assembly 30 realizes support, and the falling channel 31 realizes the guide of the bearing falling. The present invention provides a schematic diagram, which can increase or decrease the guide slope 43 according to actual conditions, or adjust the opening size. The carrier assembly 32 realizes the forward and backward movement of the supporting bearing 1 to complete the process operation. The separation assembly 33 realizes the pushing out of the half bearings on both sides, thereby realizing the falling onto two conveyor belts arranged horizontally side by side. Channel A34 is separated from channel B37 by the middle partition 35, and the U-shaped support 36 realizes lateral dislocation, thereby falling into different lanes and onto the conveyor belt.

[0138] The longitudinal bracket 38 realizes the connection, the front separation support 39 serves as the installation reference, and the separation arm 40 is above the partition plate, so that the front fingers 41 and the rear fingers 42 are distributed to push the corresponding bearing to fall. The distance between the two fingers is greater than the diameter of the processed bearing, so that the falling conveyor belt is not disturbed.

[0139] The guide slope 43 achieves a certain degree of guidance to avoid pushing the half-bearing. The longitudinal base 44 is integrated high, the longitudinal push rod part 45 achieves longitudinal pushing, the U-shaped bracket 46 achieves separate pushing, and the half-support part A47 and the half-support part B48 are used to achieve separate supporting. The arc panel seat 49 achieves two-point positioning, the side baffle 50 achieves end face support, the middle gear part 51 facilitates the passage of the tool, the rotating telescopic arm part 52 controls the pressure plate finger 53 to achieve side pressure fixation, and the elastic upper push rod 54 prevents the half-bearing from slipping out.

[0140] The present invention solves the problem of deformation caused by stress release in traditional bearing processing, which makes assembly difficult, by improving the bearing and the supporting process. It reduces noise, realizes automatic guidance, and realizes automatic dual-channel parallel output, which reduces the workload in the later stage. Its wire cutting can identify pairing according to the routing, reducing the typing head process.
