Description

Technical Field

[0001] This invention relates to the field of clamp adjustment, and in particular to a clamp centering device for an internal machine. Background Technology

[0002] Fasteners are widely used in many fields and are an indispensable part of equipment and product installation. Common fasteners usually include rivets, nuts, bolts, and nuts. Due to the large demand, fasteners are generally mass-produced using large-scale automated machines.

[0003] Currently, when traditional automated machines process rivet nuts, the clamping parts inside the machine are prone to loosening or tilting after holding the rivet nuts for a long time, which can easily lead to problems with the accuracy of product processing. In order to reduce the occurrence of such problems, the staff usually perform a centering operation on the clamps regularly to ensure that the clamping points of the clamping parts are in the exact center.

[0004] Traditionally, when adjusting the clamps, workers usually need to put their hands or heads into the machine's interior before making adjustments. To make clamp adjustments easier, workers often remove the clamp components from the machine and take them outside for adjustments. However, the entire adjustment process relies heavily on the worker's experience, which not only compromises accuracy but also reduces efficiency. This needs to be improved. Summary of the Invention

[0005] The purpose of this application is to provide a machine internal clamp centering device, which enables workers to conveniently perform centering operations on the clamp components. The whole process is time-saving and labor-saving, and effectively improves the accuracy of product processing.

[0006] This application provides a machine internal clamp centering device, which adopts the following technical solution:

[0007] A machine internal clamp centering device includes: a support platform disposed on a workbench for supporting clamp components; a limiting component disposed on the support platform for limiting the mounting rod of the clamp components; a pad disposed on the support platform; and a calibration rod disposed on the side of the pad away from the limiting component for centering the clamping portion of the clamp components.

[0008] By adopting the above technical solution, when it is necessary to debug the clamping component, the clamping component can be placed on the predetermined position of the bearing platform, and the mounting rod of the clamping component can be restricted by the limiting component, so that the clamping component can be stably restricted in the predetermined position. Then, the clamping part of the clamping component can be calibrated and debugged by the calibration rod, which makes the whole debugging process time-saving and labor-saving, and effectively improves the accuracy of subsequent product processing.

[0009] This application further provides that the limiting component includes: a limiting rod disposed on the side of the support platform away from the pad; a limiting piece rotatably connected to the limiting rod for clamping the mounting rod; and a limiting ring threadedly connected to the limiting rod.

[0010] By adopting the above technical solution, when it is necessary to restrict the clamping component, the limiting plate can be rotated so that the symmetrical limiting plate clamps the mounting rod, and then the limiting ring can be rotated to firmly fix the limiting plate, thereby restricting the clamping component to the predetermined position.

[0011] This application further provides that: the pad and the worktable are provided with U-shaped slots, the two sides of the U-shaped slots are provided with mounting blocks, the mounting blocks are rotatably connected with a rotating seat, the rotating seat is provided with two linearly symmetrical calibration rods, and the mounting blocks are also provided with locking components for limiting the calibration rods.

[0012] By adopting the above technical solution and setting two symmetrical calibration rods, if one calibration rod is damaged, the other calibration rod can be replaced by rotating the rotating seat. Then, the rotating seat is fixed with a locking device. The two calibration rods can serve as backups for unforeseen circumstances, thus improving debugging efficiency.

[0013] This application further provides that: a miniature cylinder is installed at the bottom of the workbench, and a limiting cylinder adapted to the end of the calibration rod is installed at the output end of the miniature cylinder.

[0014] By adopting the above technical solution, when the calibration rod is in the predetermined position, a miniature cylinder can be used to drive the limiting cylinder, so that the limiting cylinder is sleeved on the end of the corresponding calibration rod, thereby further locking the calibration rod on the basis of the locking component, so as to improve the stability of the calibration rod.

[0015] This application further provides that: one of the calibration rods is hollow to form a cylindrical shape, and multiple slide rods are slidably inserted into the outer wall of the calibration rod. An arc-shaped plate is fixed to the side of the slide rod away from the calibration rod, and the multiple arc-shaped plates surround the periphery of the calibration rod to form a cylindrical shape. An adjustment component is also provided inside the calibration rod for driving the slide rods to slide and causing the arc-shaped plates to move closer or further apart from each other.

[0016] By adopting the above technical solution, the adjustment component can adjust the distance between multiple arc plates, so that the arc plates surrounding the calibration rod can move closer or further apart from each other. This allows the calibration rod to be used with clamp components without changing to different sizes, effectively increasing the applicability of the calibration rod.

[0017] This application further provides that: the adjustment assembly includes: an inclined block installed on the inner end of the slide rod located on the calibration rod; a compression spring movably sleeved on the slide rod between the inclined block and the inner wall of the calibration rod, the compression spring applying a force to make the slide rod slide inwards towards the calibration rod, and a driving component for driving the slide rod to slide away from the calibration rod is also provided inside the calibration rod.

[0018] By adopting the above technical solution, when it is necessary to adjust the distance between the curved plates, the driving component can be activated to drive the sliding rod to slide. During the sliding process, the sliding rod can easily move the curved plate. This structural design is ingenious and the effect is obvious.

[0019] This application further provides that the driving component includes: a positioning rod disposed inside the calibration rod and extending in the same direction as the calibration rod; a rotating cylinder with its bottom end threadedly connected to the positioning rod and its top end extending out of the calibration rod; and an annular block that is circumferentially disposed around the rotating cylinder and adapted to the inclined block.

[0020] By adopting the above technical solution, when the rotating cylinder is rotated, it can drive the annular block to move along the extension direction of the positioning rod, so that the annular block abuts against the inclined block. The annular block cooperates with the compression spring, thereby driving the slide rod to move the arc-shaped plates closer or further apart.

[0021] This application further provides that: the inner ring of the calibration rod is provided with a plurality of fixed rods facing the rotating cylinder, and the tilting block is slidably adapted to the fixed rods through a sliding ring.

[0022] By adopting the above technical solution, the fixed rod can restrict and guide the movement direction of the tilting block based on the sliding rod, thereby improving the stability of the tilting block movement and reducing the swaying of the arc plate, so as to ensure the accuracy of the centering operation of the clamping component.

[0023] This application further provides that: a movable rod parallel to the slide rod is fixed on the side of the arc plate away from the rotating seat, the movable rod slidingly inserts into the outer wall of the calibration rod on the side away from the arc plate, and the movable rod is also provided with a scale line for measuring the distance between the arc plate and the calibration rod.

[0024] By adopting the above technical solution, the movable rod can reduce the swaying at the edge of the curved plate. It can further increase the stability of the curved plate movement based on the sliding rod and the fixed rod. At the same time, the scale lines can also make it convenient for operators to adjust the rotating cylinder by observing the displacement distance of the curved plate, which effectively improves the accuracy and further saves time and effort.

[0025] This application further provides that: the two sides of the rotating seat are rotatably connected to the mounting block via a rotating shaft; the locking element is a locking ring threaded onto the rotating shaft for clamping the mounting block; a support plate is installed at the bottom of the worktable; the base of the miniature cylinder is slidably mounted on the support plate along the extension direction of the rotating shaft; and an adjusting screw threaded through the base of the miniature cylinder is also provided on the support plate.

[0026] By adopting the above technical solution, the locking ring can not only restrict the position of the rotating seat, but also adjust the displacement of the rotating seat in the direction of the shaft extension, so that the calibration rod on the rotating seat can be adjusted to a predetermined displacement according to actual needs, further increasing the applicability of the calibration rod.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] By setting up limit components and calibration rods, the two work together to facilitate the centering operation of the clamping part of the clamp component. The whole process is time-saving, labor-saving, and more accurate. In addition, the addition of spare calibration rods can ensure work efficiency.

[0029] By setting multiple arc-shaped plates with adjustable spacing, the calibration rod can be adapted to the clamp components for calibration rods of different sizes, effectively increasing the applicability of the calibration rod. Furthermore, the locking ring and adjusting screw, when working together, can also adjust the position of the calibration rod along the extension direction of the rotating shaft, further increasing the applicability of the calibration rod.

Detailed Implementation

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] This application discloses an internal clamping and centering device for a machine, such as... Figure 1 and Figure 2 As shown, it includes: a support platform 2 mounted on the workbench 1, the support platform 2 being used to support the clamp component 10. It should be noted that in the prior art, the clamp component 10 mainly includes a plate-shaped body, with a mounting rod 11 fixed on one side of the body. The mounting rod 11 is used for assembly with the equipment. A clamping part 12 is provided on the side of the body away from the mounting rod 11. In order to make the clamp component 10 more stable, the support platform 2 and the workbench 1 in this embodiment form a predetermined acute angle.

[0036] In practice, due to prolonged operation, the center point of the clamping part 12 is prone to deviation. Generally, it is necessary for the operator to remove the clamping part 10 from the equipment for adjustment to restore the clamping center of the clamping part 12 to the predetermined position.

[0037] In this embodiment, a limiting component is provided on the support platform 2. When the clamping component 10 is located on the support platform 2, the limiting component can restrict it, thereby reducing the wobbling of the clamping component 10. A pad 3 is installed on the side of the support platform 2 away from the limiting component, and a calibration rod 30 is installed on the side of the pad 3 away from the limiting component. The calibration rod 30 is perpendicular to the pad 3. After the limiting component restricts the clamping component 10, the calibration rod 30 can facilitate the operator to adjust the clamping part 12 of the clamping component 10.

[0038] In this embodiment, the limiting component includes a limiting rod 21 disposed on the side of the support platform 2 away from the pad 3. When the clamping component 10 is located on the support platform 2, the limiting rod 21 and the mounting rod 11 are parallel to each other. A symmetrical limiting plate 22 is rotatably mounted on the limiting rod 21. At the same time, a limiting ring 23 is threadedly connected to the end of the limiting rod 21. When it is necessary to restrict the mounting rod 11 of the clamping component 10, the limiting plate 22 can be rotated so that the two limiting plates 22 are clamped on the outside of the mounting rod 11. Then, the limiting ring 23 is rotated to press against the limiting plate 22, so that the clamping component 10 can be firmly restricted on the support platform 2.

[0039] Considering that the calibration rod 30 may sometimes be damaged or need to be replaced in practice, in order not to affect work efficiency, a U-shaped groove 31 is provided on the pad 3 and the worktable 1 to communicate with each other. The opening of the U-shaped groove 31 is oriented in roughly the same direction as the extension direction of the limit rod 21. Mounting blocks 32 are fixed on both sides of the U-shaped groove 31. A rotating seat 33 is rotatably mounted between the inner sides of the mounting blocks 32. Two calibration rods 30 are arranged in a straight line symmetrically on the rotating seat 33. At the same time, a locking element is also provided on the mounting block 32. When the calibration rod 30 rotates to the predetermined position, the rotating seat 33 can be restricted by the locking element to improve the stability of the calibration rod 30.

[0040] like Figure 2 and Figure 3 As shown, in order to further improve the stability of the calibration rod 30 and improve the accuracy of the centering operation of the clamp component 10, a support plate 13 is installed at the bottom of the workbench 1. A miniature cylinder 34 is installed on the support plate 13, and a limiting cylinder 35 adapted to the end of the calibration rod 30 is installed at the output end of the miniature cylinder 34. When the calibration rod 30 is rotated to a position perpendicular to the support platform 2, the miniature cylinder 34 can be opened so that the limiting cylinder 35 is sleeved on the end of the calibration rod 30 to restrict the calibration rod 30. In addition, the calibration rod 30 can be further restricted by a locking component.

[0041] It should be noted that the two sides of the rotating seat 33 are rotatably inserted into the mounting block 32 via a rotating shaft. The locking element is a locking ring 36 threadedly connected to the rotating shaft. The locking ring 36 is located on both sides of the mounting block 32. When it is necessary to lock the rotating seat 33, it is only necessary to rotate the locking ring 36 on the rotating shaft so that the locking ring 36 clamps the mounting block 32.

[0042] It should be noted that, in this embodiment, the bottom of the miniature cylinder 34 is slidably mounted on the support plate 13 via a base, and the sliding direction is consistent with the extension direction of the rotating shaft. An adjusting screw 14 is also provided on the support plate 13. The adjusting screw 14 is threaded through the base of the miniature cylinder 34. When it is necessary to adjust the displacement of the calibration rod 30 in the extension direction of the rotating shaft, the locking ring 36 can be rotated. At the same time, the adjusting screw 14 also needs to be rotated to drive the miniature cylinder 34 to slide a predetermined displacement along the extension direction of the rotating shaft, thereby adapting to the limitation of the calibration rod 30.

[0043] In this embodiment, one of the calibration rods 30 is hollow to form a cylindrical shape. Multiple arc-shaped plates 41 are slidably arranged on the outer periphery of the calibration rod 30. The multiple arc-shaped plates 41 are assembled together to form a cylinder. A sliding rod 4 is fixed on the inner side of each arc-shaped plate 41. The sliding rod 4 is perpendicular to the calibration rod 30, and the end of the sliding rod 4 away from the arc-shaped plate 41 slides into the calibration rod 30. An inclined block 42 is fixed on the inner end of the sliding rod 4. A compression spring (not shown in the figure) is sleeved on the part of the sliding rod 4 located inside the calibration rod 30. The compression spring is located between the inclined block 42 and the inner wall of the calibration rod 30. It should be noted that the compression spring applies a force to the sliding rod 4 to slide inward toward the calibration rod 30. A driving member is also provided inside the calibration rod 30 to drive the sliding rod 4 to slide away from the calibration rod 30.

[0044] The driving component includes: a positioning rod 44 disposed inside the calibration rod 30, the positioning rod 44 being mounted on the rotating seat 33 and extending in the same direction as the calibration rod 30; a rotating cylinder 45 extending from the top of the calibration rod 30 is threaded onto the positioning rod 44; and an annular block 46 adapted to the inclined block 42 is also provided around the circumference of the rotating cylinder 45.

[0045] When it is necessary to adjust the distance between the arc plates 41, the rotating cylinder 45 can be rotated. When the rotating cylinder 45 rotates, it will drive the annular block 46 to move along the extension direction of the positioning rod 44. At the same time, the annular block 46 can also abut against the inclined surface of the inclined block 42 until it abuts against the slide rod 4 and slides on the calibration rod 30. With this solution, the distance between the arc plates 41 can be easily adjusted, thereby adapting to the needs of the clamp component 10 for calibration rods 30 of different diameters, saving the process of replacing calibration rods 30 of different diameters.

[0046] In order to reduce the shaking of the arc plate 41 during the sliding process, in this embodiment, a plurality of fixed rods 47 are provided on the inner side of the calibration rod 30, the ends of the fixed rods 47 face the rotating cylinder 45, and a sliding ring is fixed on the top of the inclined block 42, which is slidably sleeved on the fixed rods 47.

[0047] In addition, a movable rod 43 parallel to the slide rod 4 is fixed on the side of the arc plate 41 away from the rotating seat 33. The end of the movable rod 43 away from the arc plate 41 slides through the outer wall of the calibration rod 30. By setting the movable rod 43, the wobbling at the edge of the arc plate 41 can be further reduced on the basis of the fixed rod 47. In addition, in order to facilitate the operator to adjust the distance between the arc plate 41 and the calibration rod 30, in this embodiment, a scale line is set on the movable rod 43, and the scale line is arranged along the length direction of the movable rod 43.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
