Detailed Description
The invention will be described in further detail below with reference to embodiments shown in the drawings.
As shown in fig. 1 to 5, the bearing play adjusting tool of the present invention is applied to the bearing installation of the injection platform back plate of the injection molding machine, as shown in fig. 3/4, and comprises an adjusting seat 2 which is circular and has an internal thread; four support legs 21, which are L-shaped and are uniformly distributed on the adjusting seat 2, wherein one end surface is pressed on the surface of the injection platform rear plate 7, and the other end is fixed with the adjusting seat 2 into a whole; an adjusting nut 1 having an external thread; four screws 21A to 21D are provided on each leg 21, respectively.
The adjusting nut 1 is arranged in the adjusting seat 2 through the matching of external threads and internal threads, each support leg 21 surrounds the outer circumference of the bearing cover 3, the four screw rods 21A-21D respectively penetrate through each support leg 21 and the bearing cover 3 and are fixed in the ejection table rear plate 7, the adjusting nut 1 is screwed, and the end face of the adjusting nut is pressed on the end face of the bearing cover 3. As shown in fig. 3/5, the adjusting nut 1 is provided with two adjusting screws 11A and 11B.
As shown in fig. 2/3, when assembling, the outer ring and the inner ring of the self-aligning thrust roller bearing 6 are separated, and the balls are retained in the raceway of the inner ring through the retainer; the outer ring and the inner ring of the single-row tapered roller bearing 4 are separated, and the balls are retained in the raceway of the inner ring through a retainer; then, assembling the inner diameter of the inner ring of the thrust self-aligning roller bearing 6 and the shaft diameter of the transmission shaft 5 in an interference manner, and assembling the inner diameter of the inner ring of the single-row tapered roller bearing 4 and the shaft diameter of the transmission shaft 5 in an interference manner; placing an injection platform rear plate 7 perpendicular to the ground, then placing an outer ring of a self-aligning thrust roller bearing 6 at a shoulder 71 of the injection platform rear plate 7, then placing an inner ring (balls are left in the inner ring through a retainer) 61 provided with the self-aligning thrust roller bearing 6 and a transmission shaft 5 of an inner ring (balls are left in the inner ring through a retainer) of a single-row tapered roller bearing 4 in the injection platform rear plate 7, enabling the balls of the self-aligning thrust roller bearing 6 to be sleeved with a raceway of the outer ring of the self-aligning thrust roller bearing 6 in the injection platform rear plate 7, then placing the outer ring of the single-row tapered roller bearing 4 on the balls of the single-row tapered roller bearing 4, and enabling the raceway of the outer ring of the single-row tapered roller bearing 4 to be sleeved with the balls of the single-row tapered roller bearing 4; and then the bearing cover 3 is penetrated into the shooting table back plate 7, so that the outer diameter 33 of the shoulder of the bearing cover is in centering fit with the inner diameter 72 of the shooting table back plate, the inner diameter 34 of the sinking table of the bearing cover is in centering fit with the outer ring of the single-row tapered roller bearing 4, and the bottom surface of the sinking table of the bearing cover is attached to the end surface of the outer ring of the single-row tapered roller bearing. A designed gap t is reserved between the shoulder surface 36 of the bearing cover and the end surface 73 of the shooting table rear plate; the adjusting seat 2 is placed on the back plate 7 of the shooting table, the end face of the adjusting seat is attached to the end face 73 of the back plate of the shooting table, the adjusting seat 2 and the back plate 7 of the shooting table are connected into a whole through the screws 21A-21D, the adjusting nut 1 is screwed into the adjusting seat 2, the screwing depth and force of the adjusting nut 1 are controlled by the adjusting screws 11A and 11B, the contact area between the end face of the adjusting nut and the end face of the bearing cover is large, and the adjusting nut is in full-circle area contact, so that the designed and reserved gap between the shoulder end face 36 of the bearing cover and the end face 73 of the back plate of the shooting table can be well controlled, further the play of the bearing is controlled, after adjustment, the flat end fastening screws 32A-32C of the bearing cover are screwed into the threaded holes of the bearing cover and are jacked to the end face 73 of the back plate of the shooting table, then the screws 31A-31F of the bearing cover are screwed into the back plate 7 of the shooting table and tightened, the designed clearance between bearing cap shoulder end surface 36 and shooting table backplate end surface 73 can be maintained. Finally, the adjusting nut 1, the adjusting screws 11A-11B, the adjusting seat 2 and the screws 21A-21D are disassembled.
As shown in fig. 1/2, the bearing cap screws 31A to 31F and the bearing cap flat end set screws 32A to 32C alone are used to adjust the designed gap t between the transmission shaft shoulder end surface 36 and the injection platform back plate end surface 73 to control the bearing play, which is not very effective because one cannot operate the bearing cap screws 31A to 31F and the bearing cap flat end set screws 32A to 32C simultaneously to ensure that the bearing cap end surfaces are a plane. This results in either the bearing being pressed to death and the drive shaft not being able to rotate, or the bearing not being able to collapse and the drive shaft being loose. This just needs the assembly personnel to adjust repeatedly, consumes a large amount of man-hours, and the inner diameter of the race of thrust self-aligning roller bearing and the circular bead 71 of penetrating a back plate is not the centering cooperation in addition, has design reservation clearance t1, has more aggravated the degree of difficulty of adjustment.
As shown in fig. 5, after the tooling is added, the contact area between the end face 12 of the adjusting nut and the end face 37 of the bearing cap is large, and the end faces of the bearing cap are not inclined in the adjusting process because the adjusting nut and the end face 37 of the bearing cap are in area contact with each other in a whole ring. The screwing depth and force are controlled in an auxiliary mode through the adjusting screws 11A and 11B, so that the tightness of the bearing pressure can be controlled, and the designed reserved gap t between the transmission shaft shoulder end face 36 and the injection platform rear plate end face 73 can be well controlled.
To sum up, the present invention, as described in the specification and the drawings, is made into a practical sample and tested by multiple use, and from the test result, it is proved that the utility model can achieve the intended purpose, and the practicability is undoubted. The above-mentioned embodiments are merely provided for convenience of illustration of the present invention and are not intended to be limiting in form; any person skilled in the art can make local changes or modifications without departing from the scope of the present invention and the technical features and similar features disclosed in the present invention, and all equivalent embodiments using the technical content disclosed in the present invention belong to the protection scope of the present invention.
