Description

Technical Field

[0001] This utility model discloses a fixed base for a riveting machine suitable for workpieces of various diameters, and relates to the field of riveting machine processing technology. Background Technology

[0002] The riveting machine's mounting base is a crucial component, used to stabilize and support the workpiece during processing, ensuring the precision and stability of the riveting process. The base should ensure accurate positioning of the workpiece during riveting, preventing misalignment and resulting poor connections. The base is typically equipped with a clamping system to securely hold workpieces of different shapes. Adjustable design allows users to quickly adapt to different processing needs.

[0003] When riveting workpieces of different diameters and types, it is necessary to replace them with special fixtures to ensure stable clamping and accurate positioning. Otherwise, the processing accuracy may not meet the requirements, or the riveting head may shift during processing, causing damage to the device or parts to fly out and endanger the personal safety of the operators. Therefore, it is necessary to provide a fixed base for riveting machines that is suitable for workpieces of various diameters to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed base for a riveting machine suitable for workpieces of various diameters, comprising a chassis, characterized in that: the chassis is mounted on the riveting machine, a worktable is mounted on the chassis for placing workpieces, and a fixing mechanism is mounted inside the worktable for clamping and positioning the workpieces; the fixing mechanism includes a rotating shaft, which is rotatably mounted inside the worktable, a fixing block is provided on the worktable, a lower gear is mounted on the rotating shaft, horizontal racks are symmetrically mounted on both sides of the lower gear, the horizontal racks are slidably connected to the worktable, a receiving plate is provided inside the worktable, an upper gear is mounted above the receiving plate, longitudinal racks are symmetrically mounted on both sides of the upper gear, positioning frames are mounted on the longitudinal racks and horizontal racks, and a fixing block is provided on the receiving plate.

A chuck is installed on the spring, and sliding plates are symmetrically installed on both sides of the chuck. The sliding plates are slidably connected to the positioning frame.

[0007] Preferably, the fixing block abuts against the flat side of the transverse rack to restrict the transverse rack from making linear movements and prevent it from deviating, and the fixing block abuts against the flat side of the longitudinal rack to restrict the longitudinal rack from making linear movements and prevent it from deviating.

[0008] Preferably, one side of the positioning frame is connected to the horizontal rack, and the other side of the positioning frame is slidably connected to the worktable. A fixed slide is provided at the connection between the positioning frame and the worktable to limit the linear movement and movement distance of the positioning frame. One side of the positioning frame is connected to the vertical rack, and a fixed slide is provided at the connection between the positioning frame and the receiving plate to limit the linear movement and movement distance of the positioning frame. The horizontal rack moves in a horizontal linear motion in the fixed slide, and the vertical rack moves in a vertical linear motion in the fixed slide.

Through the adaptive contraction of the spring, it can adapt to the simultaneous movement of the four sets of positioning frames. After the corresponding two sets of positioning frames have contacted the surface of the workpiece to be processed, they can continue to move and clamp until the other two sets of corresponding positioning frames clamp the remaining two side surfaces of the workpiece to be processed. This realizes the clamping of workpieces of different sizes and irregular surfaces, and has a wider range of applications. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples:

[0020] like Figure 1 As shown, a fixed base for a riveting machine suitable for workpieces of various diameters includes a chassis 1, which is mounted on a riveting machine (not shown in the figure). A worktable 2 is mounted on the chassis 1 for placing workpieces. A fixing mechanism 3 is installed in the worktable 2 for clamping and positioning the workpieces. The fixing mechanism 3 is driven by a motor.

[0021] At the start of processing, the workpiece to be processed is placed on the worktable 2, and the fixing mechanism 3 is driven by the motor to adaptively position and clamp the workpiece to be processed, so as to facilitate the subsequent riveting process by the riveting machine.

[0022] like Figure 2As shown, the fixing mechanism 3 includes a rotating shaft 31, which is rotatably mounted inside the worktable 2. A lower gear 331 is mounted on the rotating shaft 31, and horizontal racks 341 are symmetrically mounted on both sides of the lower gear 331. The horizontal racks 341 are slidably connected to the worktable 2. A fixing block 35 is provided on the worktable 2, which abuts against the flat side of the horizontal racks 341 to restrict the linear movement of the horizontal racks 341 and prevent them from deviating. A positioning frame 361 is mounted on the horizontal racks 341. One side of the positioning frame 361 is connected to the horizontal racks 341, and the other side of the positioning frame 361 is slidably connected to the worktable 2. A fixed slide 37 is provided at the connection between the positioning frame 361 and the worktable 2 to restrict the linear movement and movement distance of the positioning frame 361. A receiving plate 32 is provided inside the worktable 2, and an upper gear 33 is mounted above the receiving plate 32. The upper gear 33 has longitudinal racks 34 symmetrically mounted on both sides. The transverse rack 341 is slidably connected to the receiving plate 32. The receiving plate 32 is provided with a fixing block 35, which abuts against the flat side of the longitudinal rack 34 to restrict the longitudinal rack 34 from moving in a straight line and causing it to deviate. A positioning frame 361 is mounted on the longitudinal rack 34. One side of the positioning frame 361 is connected to the longitudinal rack 34. A fixed slide 37 is provided at the connection between the positioning frame 361 and the receiving plate 32 to restrict the linear movement and movement distance of the positioning frame 361. The longitudinal racks 34 are distributed perpendicular to the transverse racks 341. The lower gear 331 and the upper gear 33 have the same size and number of teeth. The longitudinal racks 34 and the transverse racks 341 have the same length and number of teeth. A sliding groove 21 is provided at the connection between the top surface of the worktable 2 and the positioning frame 361 to restrict the linear movement of the positioning frame 361.

[0023] Among them, the motor drives the lower gear 331, which drives the horizontal rack 341 to make a horizontal linear motion under the action of the fixed slide 37, and the motor drives the upper gear 33, which drives the vertical rack 34 to make a vertical linear motion under the action of the fixed slide 37.

[0024] For ease of understanding, the movement directions of the two horizontal racks 341 are assumed to be "left" and "right", and the movement directions of the vertical rack 34 are assumed to be "up" and "down".

[0025] When positioning and clamping the workpiece, the motor controls the rotating shaft 31 to rotate, driving the lower gear 331 and the upper gear 33 to rotate. This causes the lower gear 331 to drive one horizontal rack 341 to move to the right in a straight line, and the other horizontal rack 341 to move to the left in a straight line. The upper gear 33 drives one vertical rack 34 to move upwards in a straight line, and the other vertical rack 34 to move downwards in a straight line. Because the lower gear 331 and the upper gear 33 have the same size and number of teeth, and the vertical rack 34 and the horizontal rack 341 have the same length, size, and number of teeth, the vertical rack 34 and the horizontal rack 341... 1. When moving, the distance from the rotating shaft 31 is the same. The movement of the longitudinal rack 34 and the transverse rack 341 causes the positioning frame 361 to move closer to or further away from the central axis of the rotating shaft 31, and the movement distance is equal. When positioning and clamping the workpiece to be processed, the rotating shaft 31 rotates counterclockwise, which drives the lower gear 331 and the upper gear 33 to rotate counterclockwise, pulling the outer ends of the longitudinal rack 34 and the transverse rack 341 closer to the central axis of the rotating shaft 31. The positioning frame 361 then moves closer to the central axis of the rotating shaft 31 until the workpiece is clamped, thus realizing the rapid center positioning of the workpiece to be processed.

[0026] After the workpiece is processed, the rotating shaft 31 rotates clockwise, causing the lower gear 331 and the upper gear 33 to rotate clockwise. The outer ends of the longitudinal rack 34 and the transverse rack 341 move away from the central axis of the rotating shaft 31, and the positioning frame 361 moves away from the central axis of the rotating shaft 31, thus releasing the workpiece after processing.

[0027] During processing, different diameters and different types of workpieces with varying lengths and widths can lead to unreliable clamping. To make this mechanism more applicable to workpieces of varying sizes, the specific implementation method is as follows.

[0028] The positioning frame 361 is equipped with a clamping body 36 at its upper end. The clamping body 36 includes a spring 363. The spring 363 is fixedly connected to the positioning frame 361. A chuck 362 is installed on the spring 363. Slide plates (not shown in the figure) are symmetrically installed on both sides of the chuck 362. The slide plates are slidably connected to the positioning frame 361.

[0029] When the positioning frame 361 approaches the workpiece to be processed, the chuck 362 first contacts the side surface of the workpiece. The motor drives the positioning frame 361 to continue to approach, and the spring 363 is compressed and contracted. The sliding plate retracts into the side surface of the positioning frame 361. The adaptive contraction of the spring 363 in this structure can adapt to the situation where the four sets of positioning frames 361 move at the same time. Even after two of the corresponding sets of positioning frames 361 have contacted the surface of the workpiece to be processed, they can still continue to move and clamp until the other two sets of corresponding positioning frames 361 clamp the remaining two side surfaces of the workpiece to be processed.

[0030] The chuck 362 is shaped like a deeply concave inverted "V". The clamping surface of the chuck 362 is provided with anti-slip rubber (not shown in the figure) for better clamping of the workpiece.

[0031] In summary, by controlling the rotation of the rotating shaft 31 by the motor, the lower gear 331 and the upper gear 33 are rotated, thereby causing the horizontal rack 341 and the vertical rack 34 to move the positioning frame 361 closer to or further away from the central axis of the rotating shaft 31. This achieves the center positioning and clamping of the workpiece to be processed. Through the adaptive contraction of the spring 363, it can adapt to the simultaneous movement of the four sets of positioning frames 361. Even after two sets of positioning frames 361 have contacted the surface of the workpiece to be processed, they can continue to move and clamp until the other two sets of positioning frames 361 clamp the remaining two side surfaces of the workpiece to be processed. This enables the clamping of workpieces of different sizes and irregular surfaces, and has a wider range of applications.

All technical solutions within this concept are within the scope of protection of this application. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of this application should also be considered within the scope of protection of this application.
