Description

Technical Field

[0001] This utility model relates to the field of fixed ring processing technology, specifically a multi-station processing equipment for truck axle fixed rings. Background Technology

[0002] In the truck manufacturing industry, the axle, as a key component connecting the wheels and the vehicle body, withstands various forces and vibrations during vehicle operation, making its stability and durability crucial. The retaining ring, an important part of the axle assembly, is primarily used to secure related components on the axle, ensuring they do not loosen or shift during vehicle operation.

[0003] The current fixed ring processing equipment is mainly a turntable. Multiple workstations are set on the upper surface of the turntable. Around the turntable, there are feeding mechanisms, grooving mechanisms, boring mechanisms, tapping mechanisms, and unloading mechanisms. The turntable rotates intermittently at equal angles, driving the fixed rings at the workstations to be processed by the above mechanisms, so as to achieve the purpose of automated processing.

[0004] However, in the existing technology, each workstation is equipped with a separate pneumatic clamp for fixing the fixed ring. This method not only increases the manufacturing cost of the equipment, but also brings additional costs for the maintenance and replacement of pneumatic components. In addition, it also increases the consumption of compressed air, resulting in increased energy consumption and operating costs. Utility Model Content

[0005] The purpose of this invention is to provide a multi-station processing equipment for truck axle fixing rings, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A multi-station processing device for truck axle fixing rings includes a fixed column and a turntable. The upper surface of the turntable is divided into six stations at equal angles. The turntable is rotatably mounted on the outer surface of the fixed column, and a drive mechanism for rotating the turntable is located below the outer surface of the fixed column. Each station's surface is equipped with two clamping blocks and two movable blocks via a first elastic mechanism. The first elastic mechanism applies a pushing force away from each other to the two clamping blocks and the two movable blocks. Each station's surface is equipped with a U-shaped block via a second elastic mechanism, which applies a pushing force away from the movable blocks to the U-shaped block. A first inclined surface is provided at the end of the movable block facing the U-shaped block, and second inclined surfaces are provided at both ends of the U-shaped block facing the two movable blocks, with the second inclined surfaces abutting against the first inclined surfaces. A pressing rod is connected to the surface of the U-shaped block facing the fixed column, and a pressing ring is installed on the outer surface of the fixed column, with the pressing ring abutting against the end of the pressing rod. A recess is provided on the outer surface of the pressing ring. Whenever the drive mechanism drives the turntable to rotate a certain angle, the ends of two of the pressing rods abut against the recess.

[0008] Furthermore, the drive mechanism includes an internal gear ring mounted on the lower surface of the turntable. The internal gear ring is coaxially arranged with the fixed column. A servo motor is mounted on the outer surface of the fixed column. A drive gear is mounted on the end of the output shaft of the servo motor. The drive gear meshes with the internal gear ring.

[0009] Furthermore, the first elastic mechanism includes a fixed plate mounted on the upper surface of the turntable. Two first guide rods are disposed through the interior of the fixed plate, and one end of each of the two first guide rods is connected to a clamping block. The other end of each of the two first guide rods is connected to a movable block. A first spring is sleeved on the outer surface of the first guide rod, and the two ends of the first spring abut against the movable block and the fixed plate, respectively.

[0010] Furthermore, the second elastic mechanism includes two sets of fixing blocks installed on the upper surface of the turntable. Each set of fixing blocks includes two fixing blocks arranged parallel to each other. A second guide rod is connected between the two corresponding fixing blocks, and the U-shaped block is slidably installed on the two second guide rods. A second spring is sleeved on the outer surface of the second guide rod, and the two ends of the second spring abut against the fixing block and the side of the U-shaped block facing the clamping block, respectively.

[0011] Furthermore, the turntable has clearance slots at its edge and at each workstation, the clamping block has a notch at one end near the clearance slot, and the outer surface of the clamping block has through holes.

[0012] Furthermore, the end of the extrusion rod facing the extrusion ring is provided with balls.

[0013] Furthermore, the outer surface of the extrusion ring is provided with a groove, and the outer surface of the ball matches the inner wall of the groove.

[0014] Furthermore, a fixing plate is installed at the bottom of the fixing column, and mounting holes are opened on the outer surface of the fixing plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. This utility model, through the coordinated use of components such as a drive mechanism, a first elastic mechanism, and a second elastic mechanism, enables two clamping blocks to clamp and fix the fixed ring when the extrusion rod abuts against the surface of the extrusion ring. When the extrusion rod abuts against the recessed area, the two clamping blocks can be moved away from each other, releasing the fixation of the fixed ring. Furthermore, each time the drive mechanism drives the turntable to rotate a certain angle, it will cause the ends of two of the extrusion rods to abut against the recessed area. This allows two of the workstations to perform loading and unloading operations after each turntable rotation, while the other four workstations can cooperate with other processing mechanisms for processing. Since the pneumatic clamps are eliminated, and the fixing and loosening of the fixed ring can be achieved simply by driving the turntable to rotate through the drive mechanism, no additional drive source is required. This not only reduces the equipment manufacturing cost but also facilitates later maintenance and reduces operating costs. Attached Figure Description

Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0024] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0025] Please see Figures 1-4This utility model provides a multi-station processing equipment for truck axle fixing rings, including a fixed column 100 and a turntable 101. The upper surface of the turntable 101 is divided into six stations at equal angles. The turntable 101 is rotatably mounted on the outer surface of the fixed column 100. A drive mechanism 200 capable of driving the turntable 101 to rotate is provided on the outer surface of the fixed column 100 below the turntable 101. Each station's surface is equipped with two clamping blocks 102 and two movable blocks 103 via a first elastic mechanism 300. The first elastic mechanism 300 can apply a pushing force away from each other to the two clamping blocks 102 and the two movable blocks 103. Each station's surface is equipped with a U-shaped block 104 via a second elastic mechanism 400. The second elastic mechanism 400 can apply a pushing force away from the movable blocks 103 to the U-shaped block 104. The movable block 103 has a first inclined surface 105 at its end facing the U-shaped block 104, and the U-shaped block 104 has second inclined surfaces 106 at both ends facing the two movable blocks 103. The second inclined surfaces 106 and the first inclined surfaces 105 abut against each other. A pressing rod 107 is connected to the surface of the U-shaped block 104 facing the fixed column 100. A pressing ring 108 is installed on the outer surface of the fixed column 100, and the pressing ring 108 abuts against the end of the pressing rod 107. The outer surface of the pressing ring 108 has a recess 109. Whenever the drive mechanism 200 drives the turntable 101 to rotate a certain angle, it will cause the ends of two of the pressing rods 107 to abut against the recess 109.

[0026] The compression ring 108 presses against the compression rod 107, thereby driving the U-shaped block 104 to press against the two corresponding movable blocks 103. The movable blocks 103, under pressure, push the clamping blocks 102 to move, thus allowing the two clamping blocks 102 to hold the fixing ring inside, achieving the purpose of fixation. When the end of the compression rod 107 is always in contact with the outer surface of the compression ring 108, both clamping blocks 102 maintain their clamping effect on the fixing ring. When the end of the compression rod 107 contacts the recessed area 109, the second elastic mechanism 400 pushes the U-shaped block 104 to separate from the two movable blocks 103, and the first elastic mechanism 300 pushes... The two clamping blocks 102 are moved away from each other, thereby releasing the fixing of the fixed ring. Since each time the drive mechanism 200 drives the turntable 101 to rotate a certain angle, it will cause the ends of two of the extrusion rods 107 to abut against the recessed part 109, so that the two stations can cooperate with the loading mechanism and the unloading mechanism to perform loading and unloading operations respectively. The other four stations can cooperate with other processing mechanisms to perform processing. Since the pneumatic clamps are eliminated and the fixing and loosening of the fixed ring can be achieved by driving the turntable 101 to rotate through the drive mechanism 200, no additional drive source is required. This not only reduces the equipment manufacturing cost, but also facilitates later maintenance and reduces operating costs.

[0027] Preferably, the drive mechanism 200 includes an internal gear ring 201 mounted on the lower surface of the turntable 101. The internal gear ring 201 is coaxially arranged with the fixed column 100. A servo motor 202 is mounted on the outer surface of the fixed column 100. A drive gear 203 is mounted on the end of the output shaft of the servo motor 202. The drive gear 203 meshes with the internal gear ring 201.

[0028] When the servo motor 202 is started, its output shaft drives the drive gear 203 to rotate. Since the drive gear 203 meshes with the internal gear ring 201, it can drive the turntable 101 to rotate.

[0029] Preferably, the first elastic mechanism 300 includes a fixed plate 301 mounted on the upper surface of the turntable 101. Two first guide rods 302 are disposed through the interior of the fixed plate 301, and one end of each of the two first guide rods 302 is connected to the clamping block 102. The other end of each of the two first guide rods 302 is connected to the movable block 103. A first spring 303 is sleeved on the outer surface of the first guide rod 302, and the two ends of the first spring 303 abut against the movable block 103 and the fixed plate 301, respectively.

[0030] The elastic force of the first spring 303 pushes the movable block 103 away from the fixed plate 301, and drives the clamping block 102 to move synchronously through the first guide rod 302, thereby applying a pushing force that moves away from each other to the two clamping blocks 102 and the two movable blocks 103.

[0031] Preferably, the second elastic mechanism 400 includes two sets of fixing blocks 401 mounted on the upper surface of the turntable 101. Each set of fixing blocks 401 includes two fixing blocks 401 arranged parallel to each other. A second guide rod 402 is connected between the two corresponding fixing blocks 401. The U-shaped block 104 is slidably mounted on the two second guide rods 402. A second spring 403 is sleeved on the outer surface of the second guide rod 402. The two ends of the second spring 403 abut against the fixing block 401 and the side of the U-shaped block 104 facing the clamping block 102, respectively.

[0032] The second spring 403 applies a pushing force to the U-shaped block 104 away from the clamping block 102. When the end of the extrusion rod 107 abuts against the outer surface of the extrusion ring 108, the extrusion rod 107 is compressed, which in turn pushes the U-shaped block 104 to slide on the second guide rod 402 and compress the second spring 403, so that the second inclined surface 106 and the first inclined surface 105 can press against each other and drive the two movable blocks 103 to move closer to each other. While the movable block 103 compresses the first spring 303, it drives the clamping block 102 to move through the first guide rod 302, so as to achieve the purpose of clamping and fixing the fixed ring by the two clamping blocks 102.

[0033] When the end of the compression rod 107 contacts the recessed area 109, the compressed second spring 403 releases its elastic force, pushing the U-shaped block 104 to reset, thereby causing the second inclined surface 106 and the first inclined surface 105 to move away from each other. At this time, the compression on the movable block 103 is reduced, the compressed first spring 303 releases its elastic force, thereby pushing the two movable blocks 103 away from each other, and through the first guide rod 302, driving the two clamping blocks 102 to move away from each other, releasing the clamping and fixing of the fixed ring.

[0034] Preferably, the turntable 101 has a clearance slot 500 at each work station, the clamping block 102 has a notch 501 at one end near the clearance slot 500, and the outer surface of the clamping block 102 has a through hole 502.

[0035] When the two clamping blocks 102 clamp and fix the fixed ring, the notch 501 corresponds to the relief groove 500, thereby providing enough space for the grooving mechanism to groove the fixed ring, while the through hole 502 allows the boring mechanism and the tapping mechanism to process the fixed ring.

[0036] Preferably, the end of the extrusion rod 107 facing the extrusion ring 108 is provided with ball bearings 600.

[0037] The ball bearing 600 reduces the friction between the extrusion rod 107 and the extrusion ring 108, reduces noise generation, and reduces the operating load of the servo motor 202, making the turntable 101 rotate more smoothly.

[0038] Preferably, the outer surface of the compression ring 108 is provided with a groove 700, and the outer surface of the ball 600 matches the inner wall of the groove 700.

[0039] The groove 700 provides guidance for the movement path of the ball 600, allowing it to move along a fixed trajectory on the surface of the extrusion ring 108, thus preventing the extrusion rod 107 from shaking up and down.

[0040] Preferably, a fixing plate 800 is installed at the bottom of the fixing column 100, and the outer surface of the fixing plate 800 is provided with mounting holes 801.

[0041] This equipment can be secured with bolts to ensure its stability during operation.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
