Description

[0001] This application is a divisional application of application filed on September 6, 2024, with application number 202411246735.2 and invention title "A machining press-fitting machine and its usage method". Technical Field

[0002] This invention relates to the field of machining equipment technology, specifically to a machining press-fitting machine and its usage method. Background Technology

[0003] Mechanical pressing machines are commonly used in machining. The common application of bearing pressing is to press the bearing and the workpiece together to achieve a tight and precise connection. It is highly practical. However, existing mechanical pressing machines often require manual collection of the pressed workpiece during the pressing process, which reduces pressing efficiency. There is an urgent need to improve the machines to increase work efficiency.

[0004] When pressing bearings, conventional manual operation not only reduces work efficiency but also lacks precision. The pressing of bearings cannot accurately ensure that the two workpieces are pressed on the same center. The lack of accuracy will cause the bearing to be damaged during the pressing process, resulting in high cost consumption and affecting the work progress. Summary of the Invention

[0012] Furthermore, a fixing mechanism is provided on the top of the processing table. The fixing mechanism includes a C-shaped frame fixedly installed on the top of the processing table. Two fixing round rods are fixedly installed at the bottom of the C-shaped frame. An annular fixing block is fixedly installed at the bottom end of the two fixing round rods.

[0015] Furthermore, the method of using the aforementioned machining press-fitting machine comprises the following steps:

[0016] S1: Start the drive motor. The drive motor drives the drive rod to rotate, and the drive rod drives the gripping block to rotate. When the gripping block moves and causes the gripping plate to contact the workpiece on the first feeding box, the two gripping plates will move away from each other when they contact the workpiece under the action of the gripping block. At this time, the gripping spring will contract. With the continuous movement of the gripping block, the workpiece will enter the gripping block. After the workpiece enters the gripping block, it will leave the gripping plate. Under the elastic force of the gripping spring, the gripping spring will extend and push the sliding rod to move. The sliding rod will cause the two gripping plates to move closer to each other. The movement of the gripping plates will cause the two gripping rods to move closer to each other and contact the workpiece inside the gripping block, thus positioning the workpiece inside the gripping block.

[0017] S2: After the gripping block positions the workpiece, the trapezoidal feeding plate on top of the gripping block will lift the feeding box 1. At this time, the feeding box 1 will cause the feeding spring to contract. After the feeding box 1 is lifted, the workpiece in contact with the supporting ring plate will be exposed in the feeding box 1. After the gripping block drives the workpiece in contact with the supporting ring plate to leave the feeding box 1, the trapezoidal feeding plate will leave the feeding box 1. At this time, under the elastic force of the feeding spring, it will extend and restore the feeding box 1 to its original position. The workpiece in the feeding box 1 will descend and contact the supporting ring plate. The feeding box 1, which has returned to its original position, will hold the fallen workpiece in place to prepare for the next material picking.

[0018] S3: When the drive rod rotates, it will simultaneously drive the rotating shaft to rotate under the action of the pulley and the synchronous belt. The rotating shaft drives the rotating plate to rotate, and the rotating plate will move the first movable rod. The first movable rod will drive the second movable rod to push the bearing in contact with the material box to move. After the rotating shaft rotates one revolution, the gripping block will also move the workpiece to the position where the center of the workpiece coincides with the center of the hydraulic device. The bearing pushed by the second movable rod will contact the two fixed clamping plates. The two fixed clamping plates will move away from each other and be clamped and fixed by the elastic force of the two fixed springs, so that the center of the bearing coincides precisely with the center of the workpiece.

[0019] S4: Then start the hydraulic device. The hydraulic device descends to press the workpiece and bearing. After pressing, the hydraulic device rises, which drives the synchronous block to rise. The synchronous block drives the transmission rod one to rise, which drives the transmission block to rise. The transmission block drives the transmission rod two to move closer to the hydraulic device. The transmission rod two drives the movable rectangular block to move. Since the height of the workpiece is higher than the gripping block, the collecting push rod of the movable rectangular block pushes the pressed workpiece. Under the thrust of the collecting push rod, the workpiece is pushed into the collecting slide plate for collection. When the gripping block moves, the workpiece inside the gripping block will touch the collecting push rod. The collecting push rod will rise in the rectangular limit groove and the T-shaped movable groove.

[0020] The present invention has the following beneficial effects:

[0021] (1) The present invention provides a mechanical processing press fitting machine. When the drive motor is started, the drive motor drives the drive rod to rotate, and the drive rod drives the gripping block to rotate. When the gripping block moves and drives the gripping plate to contact the installation workpiece on the first feeding box, under the action of the gripping block, the two gripping plates will move away from each other when they contact the installation workpiece. At this time, the gripping spring contracts. With the continuous movement of the gripping block, the installation workpiece enters the gripping block. After the installation workpiece enters the gripping block, the installation workpiece will leave the gripping plate at the same time. Under the action of the elastic force of the gripping spring, the gripping spring will extend and push the sliding rod to move. The sliding rod drives the two gripping plates to approach each other. The movement of the gripping plates will drive the two gripping rods to approach each other and contact the installation workpiece in the gripping block, thereby positioning the installation workpiece in the gripping block and improving the accuracy of press fitting.

[0022] (2) In the present invention, a mechanical processing press-fitting machine, after the gripping block positions the installation workpiece, the trapezoidal feeding plate at the top of the gripping block will lift the feeding box one. At this time, the feeding box one drives the feeding spring to contract. After the feeding box one is lifted, the installation workpiece in contact with the supporting ring plate will be exposed out of the feeding box one. After the gripping block drives the installation workpiece in contact with the supporting ring plate to leave the feeding box one, the trapezoidal feeding plate will leave the feeding box one. At this time, under the elastic force of the feeding spring, it will elongate and restore the feeding box one to its original position. The installation workpiece in the feeding box one will descend and contact the supporting ring plate. The feeding box one, which has returned to its original position, will hold the fallen installation workpiece in place to prepare for the next material picking.

[0023] (3) The present invention provides a mechanical processing press-fitting machine. When the drive rod rotates, it will simultaneously drive the rotating shaft to rotate under the action of the pulley and the synchronous belt. The rotating shaft drives the rotating plate to rotate. The rotating plate will move the movable rod one. The movable rod one drives the movable rod two to push the bearing in contact with the material box to move. After the rotating shaft rotates one revolution, the gripping block will also move the workpiece to the position where the center of the workpiece coincides with the center of the hydraulic device. The bearing pushed by the movable rod two will contact the two fixed clamping plates. The two fixed clamping plates will move away from each other and be clamped and fixed by the elastic force of the two fixed springs, so that the center of the bearing coincides with the center of the workpiece, further improving the accuracy of press-fitting.

[0024] (4) The present invention provides a mechanical pressing machine. Then, the hydraulic device is started. The hydraulic device descends to press the workpiece and bearing. After pressing, the hydraulic device rises. The hydraulic device drives the synchronous block to rise. The synchronous block drives the transmission rod one to rise. The transmission rod one drives the transmission block to rise. The transmission block drives the transmission rod two to move towards the hydraulic device. The transmission rod two drives the movable rectangular block to move. Since the height of the workpiece is higher than the gripping block, the collecting push rod of the movable rectangular block pushes the pressed workpiece. Under the pushing force of the collecting push rod, the workpiece is pushed into the collecting slide plate for collection. When the gripping block moves, the workpiece in the gripping block will touch the collecting push rod. The collecting push rod will rise in the rectangular limit groove and the T-shaped movable groove to avoid jamming.

[0039] Two sliding rods 103 are respectively fitted with fixing plates 104, and two gripping springs 105 are respectively fitted on the two sliding rods 103. The ends of the two gripping springs 105 that are close to each other are respectively fixedly connected to two L-shaped plates 102, and the ends of the two gripping springs 105 that are far apart from each other are respectively fixedly connected to two fixing plates 104. Gripping plates 106 are respectively fixedly installed on the ends of the two sliding rods 103 that are close to each other. The sides of the two gripping plates 106 that are close to each other both extend into the gripping block 101 and are both gripped. Block 101 is slidably connected. Limiting grooves 107 are respectively opened on the left and right inner walls of the gripping block 101. Limiting rods 108 are fixedly installed in the two limiting grooves 107.

[0040] like Figure 1 and Figure 4 As shown, a support mechanism 2 is provided on the top of the processing table 1. The support mechanism 2 includes several support rods 201 fixedly installed on the top of the processing table 1. A support ring plate 202 is fixedly installed on the top of the several support rods 201. A drive motor 203 is fixedly installed on the bottom of the processing table 1.

Two collection slide plates 206 are fixedly installed on the top of the processing table 1.

[0041] Start the drive motor 203, which drives the drive rod 204 to rotate. The drive rod 204 drives the gripping block 101 to rotate, providing driving force. During pressing, the supporting ring plate 202 can provide sufficient support to ensure the stability of pressing.

[0042] like Figure 4 As shown, a feeding mechanism 3 is provided on the top of the processing table 1. The feeding mechanism 3 includes a rectangular rod 301 fixedly installed on the top of the processing table 1. A feeding box 302 is slidably installed on the rectangular rod 301. A feeding plate 303 is fixedly installed on the top of the rectangular rod 301. A feeding spring 304 is sleeved on the rectangular rod 301. The top of the feeding spring 304 is fixedly connected to the feeding plate 303. The bottom of the feeding plate 303 is fixedly connected to the feeding box 302. A number of workpieces 305 are arranged in the feeding box 302.

[0043] After the gripping block 101 positions the installation workpiece 305, the trapezoidal feeding plate 306 on the top of the gripping block 101 will lift the feeding box 302. At this time, the feeding box 302 will cause the feeding spring 304 to contract. After the feeding box 302 is raised, the installation workpiece 305 that is in contact with the supporting ring plate 202 will be exposed in the feeding box 302. After the gripping block 101 drives the installation workpiece 305 that is in contact with the supporting ring plate 202 to leave the feeding box 302, the trapezoidal feeding plate 306 will leave the feeding box 302. At this time, under the elastic force of the feeding spring 304, it will extend and restore the feeding box 302 to its original position. The installation workpiece 305 in the feeding box 302 will descend and contact the supporting ring plate 202. The feeding box 302, which has returned to its original position, will hold the fallen installation workpiece 305 in place, preparing for the next material picking.

[0044] like Figure 1 and Figure 5 As shown, a material feeding mechanism 4 is provided on the top of the processing table 1. The material feeding mechanism 4 includes a rotating shaft 401 rotatably mounted on the top of the processing table 1. A rotating plate 402 is fixedly mounted on the top of the rotating shaft 401. A movable rod 403 is hingedly mounted on the top of the rotating plate 402. A movable rod 404 is hingedly mounted on the left end of the movable rod 403. A material conveying box 405 is fixedly mounted on the top of the processing table 1. The left end of the movable rod 404 extends into the material conveying box 405 and is slidably connected to the material conveying box 405. A material feeding box 406 is fixedly mounted on the top of the material feeding box 405. Several bearings 407 are provided inside the material feeding box 406. Pulleys 408 are fixedly sleeved on the rotating shaft 401 and the drive rod 204 respectively. Synchronous belts 409 are sleeved on the two pulleys 408.

[0045] When the drive rod 204 rotates, it will simultaneously drive the rotating shaft 401 to rotate under the action of the pulley 408 and the synchronous belt 409. The rotating shaft 401 drives the rotating plate 402 to rotate, and the rotating plate 402 will move the movable rod 1 403. The movable rod 1 403 drives the movable rod 2 404 to push the bearing 407 that is in contact with the material box 405 to move. After the rotating shaft 401 rotates one revolution, the gripping block 101 will also move the installed workpiece 305 to a position where the center of the circle coincides below the hydraulic device 600. The bearing 407 pushed by the movable rod 2 404 will contact the two fixed clamping plates 504.

[0046] like Figure 6 As shown, a fixing mechanism 5 is provided on the top of the processing table 1. The fixing mechanism 5 includes a U-shaped frame 501 fixedly installed on the top of the processing table 1. Two fixing round rods 502 are fixedly installed at the bottom of the U-shaped frame 501. Annular fixing blocks 503 are fixedly installed at the bottom ends of the two fixing round rods 502. Two fixing clamps 504 are hinged to the bottom of the annular fixing blocks 503. Two fixing springs 505 are fixedly installed on the side of the two fixing clamps 504 that are close to each other.

[0047] The two fixed clamping plates 504 will move away from each other and be clamped and fixed by the elastic force of the two fixed springs 505, so that the center of the bearing 407 and the center of the workpiece 305 are precisely aligned, further improving the accuracy of press fitting.

[0048] like Figure 6 As shown, a transmission mechanism 6 is provided at the bottom of the C-shaped frame 501. The transmission mechanism 6 includes a hydraulic device 600 fixedly installed at the bottom of the C-shaped frame 501. A synchronizing block 601 is fixedly sleeved on the hydraulic device 600. A transmission rod 602 is fixedly installed on the right side of the synchronizing block 601. A limiting round rod 603 is fixedly installed at the bottom of the C-shaped frame 501. A transmission block 604 is slidably installed on the limiting round rod 603. The transmission rod 602 is fixedly connected to the transmission block 604. A transmission rod 605 is hingedly installed on the right side of the transmission block 604.

[0049] After the pressing is completed, the hydraulic device 600 rises, which drives the synchronous block 601 to rise. The synchronous block 601 drives the transmission rod 602 to rise, the transmission rod 602 drives the transmission block 604 to rise, and the transmission block 604 drives the transmission rod 605 to move closer to the hydraulic device 600. The transmission rod 605 drives the movable rectangular block 702 to move.

[0050] like Figure 7 As shown, a collection mechanism 7 is provided on the U-shaped frame 501. The collection mechanism 7 includes a transmission box 701 fixedly installed on the inner wall of the right side of the U-shaped frame 501. A movable rectangular block 702 is slidably installed inside the transmission box 701. Strip-shaped limiting grooves 703 are respectively opened on the inner wall of the front and back of the transmission box 701. Rectangular limiting blocks 704 are fixedly installed on the front and back of the movable rectangular block 702. The sides of the two rectangular limiting blocks 704 that are far apart from each other extend into the two strip-shaped limiting grooves 703. The inner part is slidably connected to two strip-shaped limiting grooves 703 respectively. A T-shaped movable groove 705 is opened in the movable rectangular block 702. A collecting push rod 706 is slidably installed in the T-shaped movable groove 705. A limiting rectangular block 707 is fixedly installed on the bottom inner wall of the transmission box 701. A rectangular limiting groove 708 is opened on the limiting rectangular block 707. The left end of the collecting push rod 706 extends to the outside of the movable rectangular block 702. The collecting push rod 706 passes through the rectangular limiting groove 708 and is slidably connected to the rectangular limiting groove 708.

[0051] Since the height of the installation workpiece 305 is higher than that of the gripping block 101, the collection push rod 706 of the movable rectangular block 702 pushes the press-fitted installation workpiece 305. Under the pushing force of the collection push rod 706, the installation workpiece 305 is pushed into the collection slide plate 206 for collection. When the gripping block 101 moves, the installation workpiece 305 in the gripping block 101 will touch the collection push rod 706. The collection push rod 706 will rise in the rectangular limit groove 708 and the T-shaped movable groove 705 to avoid jamming.

[0052] like Figure 1-8 The following is a method for using a machining press-fitting machine:

[0053] S1: Start the drive motor 203. The drive motor 203 drives the drive rod 204 to rotate, and the drive rod 204 drives the gripping block 101 to rotate. When the gripping block 101 moves and causes the gripping plate 106 to contact the installation workpiece 305 on the discharge box 302, under the action of the gripping block 101, the two gripping plates 106 will move away from each other when they contact the installation workpiece 305. At this time, the gripping spring 105 will contract. With the continuous movement of the gripping block 101, the installation workpiece 305 is allowed to enter. Once inside the gripping block 101, after the installation workpiece 305 enters the gripping block 101, it will simultaneously leave the gripping plate 106. Under the elastic force of the gripping spring 105, the gripping spring 105 will extend and push the sliding rod 103 to move. The sliding rod 103 will drive the two gripping plates 106 to move closer to each other. The movement of the gripping plates 106 will drive the two gripping rods 110 to move closer to each other and contact the installation workpiece 305 inside the gripping block 101, thereby positioning the installation workpiece 305 inside the gripping block 101.

[0054] S2: After the gripping block 101 positions the installation workpiece 305, the trapezoidal feeding plate 306 on the top of the gripping block 101 will lift the feeding box 302. At this time, the feeding box 302 will cause the feeding spring 304 to contract. After the feeding box 302 is lifted, the installation workpiece 305 that is in contact with the support ring plate 202 will be exposed in the feeding box 302. After the gripping block 101 drives the installation workpiece 305 that is in contact with the support ring plate 202 to leave the feeding box 302, the trapezoidal feeding plate 306 will leave the feeding box 302. At this time, under the elastic force of the feeding spring 304, it will extend and restore the feeding box 302 to its original position. The installation workpiece 305 in the feeding box 302 will descend and contact the support ring plate 202. The feeding box 302, which has returned to its original position, will hold the fallen installation workpiece 305 to prepare for the next material picking.

[0055] S3: When the drive rod 204 rotates, it will simultaneously drive the rotating shaft 401 to rotate under the action of the pulley 408 and the synchronous belt 409. The rotating shaft 401 drives the rotating plate 402 to rotate. The rotating plate 402 will move the movable rod 1 403. The movable rod 1 403 drives the movable rod 2 404 to push the bearing 407 that is in contact with the material box 405 to move. After the rotating shaft 401 rotates one revolution, the gripping block 101 will also move the installed workpiece 305 to a position where the center of the bearing 305 coincides with the center of the hydraulic device 600. The bearing 407 pushed by the movable rod 2 404 will contact the two fixed clamping plates 504. The two fixed clamping plates 504 will move away from each other and be clamped and fixed by the elastic force of the two fixed springs 505, so that the center of the bearing 407 coincides precisely with the center of the installed workpiece 305.

[0056] S4: Then, the hydraulic device 600 is activated. The hydraulic device 600 descends to press the installation workpiece 305 and bearing 407. After pressing, the hydraulic device 600 rises, driving the synchronous block 601 to rise. The synchronous block 601 drives the transmission rod 1 602 to rise, and the transmission rod 1 602 drives the transmission block 604 to rise. The transmission block 604 drives the transmission rod 2 605 to move closer to the hydraulic device 600. The transmission rod 2 605 drives the movable rectangular block 702 to move. Since the height of the installation workpiece 305 is higher than that of the gripping block 101, the collecting push rod 706 of the movable rectangular block 702 pushes the pressed installation workpiece 305. Under the thrust of the collecting push rod 706, the installation workpiece 305 is pushed into the collecting slide plate 206 for collection. When the gripping block 101 moves, the installation workpiece 305 in the gripping block 101 will touch the collecting push rod 706. The collecting push rod 706 will rise within the rectangular limiting groove 708 and the T-shaped movable groove 705.

2. The method of using a machining press-fitting machine according to claim 1, characterized in that, The steps are as follows: S1: Start the drive motor (203). The drive motor (203) drives the drive rod (204) to rotate. The drive rod (204) drives the gripping block (101) to rotate. When the gripping block (101) moves and drives the gripping plate (106) to contact the installation workpiece (305) on the first discharge box (302), under the action of the gripping block (101), the two gripping plates (106) will move away from each other when they contact the installation workpiece (305). At this time, the gripping spring (105) contracts. With the continuous movement of the gripping block (101), the installation workpiece (305) enters the... Inside the gripping block (101), after the installation workpiece (305) enters the gripping block (101), the installation workpiece (305) will leave the gripping plate (106). Under the elastic force of the gripping spring (105), the gripping spring (105) will extend and push the sliding rod (103) to move. The sliding rod (103) will drive the two gripping plates (106) to move closer to each other. The movement of the gripping plates (106) will drive the two gripping rods (110) to move closer to each other and contact the installation workpiece (305) inside the gripping block (101) to position the installation workpiece (305) inside the gripping block (101). S2: After the gripping block (101) positions the installation workpiece (305), the trapezoidal feeding plate (306) on top of the gripping block (101) will lift the feeding box (302). At this time, the feeding box (302) will cause the feeding spring (304) to contract. After the feeding box (302) is lifted, the installation workpiece (305) in contact with the supporting ring plate (202) will be exposed in the feeding box (302). After the workpiece (305) leaves the first feeding box (302), the trapezoidal feeding plate (306) leaves the first feeding box (302). At this time, under the elastic force of the feeding spring (304), the first feeding box (302) will be extended and return to its original position. The installed workpiece (305) in the first feeding box (302) will descend and contact the supporting ring plate (202). The first feeding box (302) that has returned to its original position will hold the fallen installed workpiece (305) in place to prepare for the next material picking. S3: When the drive rod (204) rotates, it will simultaneously drive the rotating shaft (401) to rotate under the action of the pulley (408) and the synchronous belt (409). The rotating shaft (401) drives the rotating plate (402) to rotate. The rotating plate (402) will drive the movable rod one (403) to move. The movable rod one (403) drives the movable rod two (404) to push the bearing (407) in contact with the material box (405) to move. After the rotating shaft (401) rotates one revolution, the gripping block (101) will also move the installed workpiece (305) to the position where the center of the circle coincides with the center of the circle below the hydraulic device (600). The bearing (407) pushed by the movable rod two (404) will contact the two fixed clamping plates (504). The two fixed clamping plates (504) will move away from each other and be clamped and fixed by the elastic force of the two fixed springs (505), so that the center of the bearing (407) and the center of the installed workpiece (305) are precisely coincident. S4: Then start the hydraulic device (600). The hydraulic device (600) descends to press the workpiece (305) and bearing (407) into place. After pressing, the hydraulic device (600) rises. The hydraulic device (600) drives the synchronous block (601) to rise. The synchronous block (601) drives the transmission rod one (602) to rise. The transmission rod one (602) drives the transmission block (604) to rise. The transmission block (604) drives the transmission rod two (605) to move closer to the hydraulic device (600). As the transmission rod 2 (605) moves, it drives the movable rectangular block (702) to move. Since the height of the installation workpiece (305) is higher than that of the gripping block (101), the collecting push rod (706) of the movable rectangular block (702) pushes the press-fitted installation workpiece (305). When the gripping block (101) moves, the installation workpiece (305) in the gripping block (101) will touch the collecting push rod (706), and the collecting push rod (706) will rise in the rectangular limiting groove (708) and the T-shaped movable groove (705).
