Description

Technical Field

[0001] This invention belongs to the field of press-fitting machine tool technology, specifically a double-end synchronous intelligent press-fitting combination machine tool for idler roller bearing seats. Background Technology

[0002] As a core component of belt conveyors, the rotational resistance and service life of idler rollers directly affect the operating efficiency of the entire conveyor line. In traditional technology, the idler roller bearing housing press-fitting process mainly relies on single-end hydraulic or pneumatic presses. The working mode is usually as follows: the operator first puts the bearing assembly into one end of the roller and presses it in with one machine; then the workpiece is flipped over and the bearing assembly at the other end is pressed in with another machine. This has low production efficiency and cannot meet the needs of mass production. Although some existing double-end press-fitting equipment can achieve synchronous press-fitting of the idler roller bearing housings at both ends, it only achieves approximately synchronous movement of the two press heads in time. It lacks precise and coordinated control of the force during the press-fitting process and cannot guarantee the absolute concentricity of the press-fitting at both ends, which can easily lead to uneven wear of the bearings. In addition, when there is tilting or eccentricity in the press-fitting of the bearing housing, it cannot effectively detect, mark or simply correct it, resulting in low level of intelligence.

[0049] Please see Figures 1-8 In this embodiment of the invention, a double-end synchronous intelligent pressing combination machine tool for idler roller bearing housing includes:

[0050] Machine tool body 1;

[0051] The base 11 is symmetrically fixed on both sides of the upper end face of the machine tool body 1;

[0052] The transfer seat 12 is horizontally slidably mounted on each of the bases 11 via a ball screw;

[0053] The pressing unit 2 is fixed on the two transfer seats 12 and is symmetrically distributed. The two transfer seats 12 can be adjusted to slide left and right to achieve the two pressing units 2 being symmetrically distributed on both sides of the machine tool body 1.

[0054] The pallet seat 13 is fixed at the center of the upper end face of the machine tool body 1 and located between two bases 11. A support base plate 14 is slidably mounted on the pallet seat 13. Two roller support frames 15 are symmetrically fixed on the support base plate 14. The roller support frames 15 are used to horizontally lift the rollers to be pressed. At this time, the two ends of the rollers are respectively facing each pressing unit 2.

[0055] The feeding unit 3 is configured as two units and is fixed on one side of the base 11 respectively, for feeding and conveying the bearing seats one by one.

[0056] In this embodiment, the feeding unit 3 includes:

[0057] The assembly plate 31 is vertically fixed on the base plate 11, and a mounting plate 32 is fixed to one side of the assembly plate 31 in parallel by a plurality of fixing posts.

[0058] Positioning plate 33 is fixed above one side end face of mounting plate 32;

[0059] Link 34 is horizontally slidably connected to the positioning plate 33;

[0060] A fixing plate 35 is fixed to one end of the connecting rod 34. A clamping plate 36 is installed on one side end face of the fixing plate 35. A clamping shaft is provided at the center of the clamping plate 36, so that the center of the bearing seat can be temporarily fixed by the clamping shaft.

[0061] An external plate 37 is fixed on the positioning plate 33 and located below the fixing plate 35. The external plate 37 has multiple fixing holes.

[0062] The feeding rack 4 is fixed on the outer plate 37 and connected to the fixing holes by multiple bolts. The feeding rack 4 has a feeding slot, and multiple bearing seats are arranged and transported in the feeding slot. Two electric clamps 41 are symmetrically fixed at one end of the feeding rack 4 near the clamping plate 36. They can clamp and position the bearing seats fed at the end. Together with the clamping shaft, they form a "one clamp and one pass" cooperative positioning mode, thereby realizing the one-to-one transmission and feeding of bearing seats, avoiding equipment failure and production interruption caused by multiple parts sticking, jamming or simultaneous feeding.

[0063] An electric telescopic rod 42 is horizontally fixed on the positioning plate 33. One end of the electric telescopic rod 42 is connected to the fixed plate 35. During the feeding and conveying of the bearing seat, the electric telescopic rod 42 is in a retracted state, and the clamping plate 36 is directly opposite the feeding slot of the feeding rack 4. After the bearing seat is unloaded, the electric telescopic rod 42 pushes the clamping plate 36 to move horizontally and align it with the pressing unit 2 so that the pressing unit 2 can remove the bearing seat from the clamping plate 36.

[0064] In a preferred embodiment, the center of the feeding slot is directly opposite the clamping plate 36, and one end of the feeding frame 4 is provided with a pushing cylinder (not shown in the figure).

[0065] A positioning tube 43 is horizontally fixed on the positioning plate 33. One end of the positioning tube 43 is threadedly slidably connected to a limit rod, which can partially extend out of the positioning tube 43 during threaded adjustment. The other end of the connecting rod 34 is fixed with a stop 44, which can limit the horizontal sliding of the connecting rod 34 by the stop 44, thereby preventing the electric telescopic rod 42 from over-extending and causing the clamping plate 36 to not align with the pressing unit 2, thus improving the docking and feeding accuracy.

[0066] In addition, the mounting plate 31 in this device may be equipped with a height adjuster, which can adjust the relative height of the clamp 36.

[0067] In this embodiment, the pressing unit 2 includes:

[0068] Frame 21, with a slide rail fixed horizontally on its upper end face;

[0069] An adjusting seat 22 is slidably mounted on the slide rail. A guide post 23 is horizontally slidably connected to the frame 21. One end of the guide post 23 is fixed to the adjusting seat 22 by a bracket.

[0070] A press-fit sleeve 24 is fixed on the side of the adjusting seat 22 away from the guide post 23, and a plurality of support rods 25 are connected between the press-fit sleeve 24 and the adjusting seat 22;

[0071] The pressing shaft 5 is coaxially connected inside the guide post 23, and one end of the pressing shaft 5 slides into and connects to the pressing sleeve 24. Specifically, before feeding, the adjusting seat 22 is located on the side of the frame 21 close to the feeding unit 3. The feeding unit 3 transports the bearing seat to the pressing sleeve 24. At this time, the bearing seat and the pressing sleeve 24 are coaxially distributed. During the pressing process, the adjusting seat 22 is adjusted horizontally along the slide rail so that the end of the pressing sleeve 24 abuts against the end of the idler roller. At this time, the two pressing sleeves 24 distributed on the left and right can form a clamping action on the idler roller to prevent relative displacement during the pressing process. Then, the pressing shafts 5 push the bearing seat into the assembly groove of the idler roller in the axial synchronous sliding.

[0072] In this embodiment, a first hydraulic chamber 26 is provided inside the guide post 23, and a first piston 27 is sleeved on the press-fit shaft. The first piston 27 is slidably connected in the first hydraulic chamber 26.

[0073] The side wall of the guide post 23 is provided with an inlet hole that is sealed and connected to the first hydraulic chamber. A hydraulic pipe is connected to the outside of the inlet hole, which can hydraulically push the first piston 27 to slide horizontally, while the pressing shaft 5 smoothly presses the bearing seat into the idler roller under hydraulic drive.

[0074] In this embodiment, a slot 51 is provided at the center of one end of the pressing shaft 5. On the one hand, it can facilitate the temporary insertion of the clamping shaft during the material feeding process of the bearing seat, and on the other hand, it can facilitate the temporary insertion of the inner shaft of the idler roller during the pressing process of the bearing seat, so that the pressing sleeve 24 can fully abut against the end of the idler roller.

[0075] Multiple guide shafts 6 are distributed around the inner circumference of the pressing shaft 5, and each guide shaft 6 is slidably connected to the pressing shaft 5. A fixed shaft 52 is slidably connected coaxially inside the pressing shaft 5. A support spring is connected between the fixed shaft 52 and the pressing shaft 5. A guide plate 53 is rotatably connected to the fixed shaft 52 via a ball joint. Multiple transmission rods corresponding to the guide shafts 6 are hinged to the guide plate 53. It should be noted that the support spring can cause the fixed shaft 52 to slide away from the pressing sleeve 24 under the action of elastic force. At this time, each guide shaft 6 is inside the pressing shaft 5, so that the bearing seat is smoothly pressed in the initial pressing stage only through the pressing shaft 5.

[0076] An inner shaft rod 54 is slidably connected inside the press-fitting shaft 5. One end of the inner shaft rod 54 is fixed with a slanted push plate 55. When the inner shaft rod 54 slides towards the side of the press-fitting sleeve 24, the support spring is gradually compressed. At this time, the inclined surface of the slanted push plate 55 gradually comes into contact with the guide plate 53, and the guide plate 53 deflects. The end of a guide shaft 6 at the corresponding position can extend out of the press-fitting shaft 5 first.

[0077] In a preferred embodiment, a soft pad 56 is installed at the end of the pressing shaft 5. After the initial pressing, the soft pad 56 (made of a polymer material such as polyurethane) forms a flexible contact with the end face of the bearing seat. Here, after the bearing seat is initially pressed, its pressing angle can be detected. If there is a pressing tilt or eccentricity, the inclined push plate 55 rotates to a specified angle and is controlled by the inner shaft rod 54 to slide axially, thereby gradually compressing the support spring. At this time, a corresponding guide shaft 6 can partially extend out of the pressing shaft 5. The pressing shaft 5 then performs the pressing action again and uses the corresponding guide shaft 6 to correct the tilt position of the bearing seat.

[0078] Therefore, in this device, the local extension amount of the corresponding guide shaft 6 can be controlled by the inner shaft rod 54 and the inclined push plate 55. The extension force and stroke of the guide shaft can be precisely controlled and adjusted, avoiding overcorrection or undercorrection.

[0079] A rotating shaft 57 is rotatably connected inside the guide post 23. One end of the rotating shaft 57 is slidably connected to the inner shaft rod 54. A control motor 58 is fixed outside the guide post 23. The output end of the control motor 58 is connected to the rotating shaft 57 through gear meshing. The control motor 58 can achieve synchronous rotation of the rotating shaft 57 in both forward and reverse rotations. During rotation, the rotating shaft 57 drives the inner shaft rod 54 and the inclined push plate 55 to deflect synchronously. In this way, on the one hand, the inclined push plate 55 can partially push out a corresponding guide shaft 6. On the other hand, when the rotating shaft 57 continues to rotate, each guide shaft 6 can be partially pushed out in sequence and abut against the bearing seat. The inclined pusher 55 continuously rotates to push out each guide shaft 6 sequentially after the bearing housing has been initially press-fitted. Each guide shaft 6 then presses against the bearing housing one by one, and a pressure sensor detects and acquires the contact pressure at each position. Based on the acquired circumferential pressure distribution data, the direction (angle) and severity (magnitude) of the bearing housing eccentricity can be accurately calculated. For example, simple tilting is manifested as a continuously high pressure on one side and a low pressure on the other side; while the presence of foreign objects or local deformation is manifested as an abnormal pressure peak at a specific point. This setting can effectively perform intelligent positioning detection on the press-fitted bearing housing, and can subsequently correct bearing housings with press-fit defects.

[0080] In this embodiment, a second hydraulic chamber is provided inside the press-fitting shaft 5, and a ring sleeve 7 is rotatably sleeved on the inner shaft rod 54. A second piston 71 is fixed on the ring sleeve 7. The second piston 71 is slidably connected in the second hydraulic chamber, and one end of the second piston 71 is connected to a limit spring, which can use the elastic force to control the second piston 71 to slide away from the press-fitting sleeve 24.

[0081] The side wall of the second hydraulic chamber is provided with a side hole 72;

[0082] A straight guide groove 73 is provided inside the guide post 23. The straight guide groove 73 is connected to the side hole 72. A shaft hole is connected to the outside of the straight guide groove 73. It should be noted that the length of the straight guide groove 73 is greater than the sliding displacement of the inner shaft rod 54 so that the straight guide groove 73 can always be sealed and connected with the side hole 72 on the inner shaft rod 54. When the hydraulic oil enters the second hydraulic chamber through the straight guide groove 73, it can hydraulically push the second piston 71 to slide horizontally. The inner shaft rod 54 slides towards the side of the press-fit sleeve 24, and the inclined push plate 55 gradually contacts the guide plate 53, thereby effectively controlling the extension amount of the single guide shaft 6 relative to the press-fit shaft 5.

[0083] In this embodiment, the guide shaft 6 is configured as a two-section telescopic structure, with the two sections connected by an inner spring, and a vibration guide sleeve 61 is sleeved at the end of one section. A conductive ring 62 is fixed inside the guide shaft 6, and multiple vibration terminals 63 are distributed between the vibration guide sleeve 61 and the guide shaft 6.

[0084] A pressure sensor (not shown in the figure) is provided on the vibration guide sleeve 61.

[0085] Another section of the guide shaft 6 is fixed with a shaft disk 64, on which multiple electrical contacts 65 are provided. Especially during bearing seat correction, the corresponding guide shaft 6 partially extends out of the press-fit shaft 5. The press-fit shaft 5 is hydraulically driven to perform a press-fit action again. At this time, the soft pad layer 56 is compressed and deformed, and the guide shaft 6 and the bearing seat come into contact. As the press-fit shaft 5 continues to press down, the inner spring between the two sections of the guide shaft 6 is compressed, and the electrical contacts 65 on the shaft disk 64 make electrical contact with the conductive ring 62. Each vibration terminal controls the end of the vibration guide sleeve 61 to vibrate, thereby using the vibration guide sleeve 61 to fully push the inclined position of the bearing seat into the idler roller, thereby realizing the position correction of the bearing seat. After the correction is completed, the rotating shaft 57 can be used to continuously rotate, and the contact pressure at each position can be detected again by the pressure sensor, which is convenient for subsequent judgment on whether the bearing seat is installed in place and whether manual intervention is required for correction.

[0086] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
