Description

Technical Field

[0001] The utility model relates to the technical field of mechanical parts production, and particularly relates to a clamping device with an anti-bouncing function. Background Technique

[0002] Mechanical processing refers to the process of changing the shape size or performance of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing. With the rapid development of modern mechanical processing, mechanical processing technology has developed rapidly, and many advanced mechanical processing technology methods have gradually emerged, such as micro mechanical processing technology, rapid prototyping technology, and precision ultra-precision processing technology.

[0003] When machining columnar mechanical parts, a clamping device will be used. When machining them, it is necessary to clamp them to prevent deviation during machining. However, when the existing clamping device clamps the workpiece, if the operator does not close the clamping device in time, the clamping force will be too large, resulting in deformation of the workpiece and even breakage in severe cases, causing unnecessary losses. Content of the Utility Model

[0004] The purpose of the utility model is to provide a clamping device with an anti-bouncing function to solve the problems raised in the above background technique.

A moving plate is slidably connected to the top of the operating table. A clamping component and a protection component are arranged on the surface of the moving plate. The clamping component includes: a circular plate, a first chute, a slider, a groove, a linkage plate, a first spring, a stabilizing rod, an arc-shaped clamping plate, a second spring, and a bolt. There are three groups of sliders, and the three groups of sliders are circumferentially arranged around the center of the circular plate. The protection component includes:

[0006] A concave-shaped frame, the concave-shaped frame is fixed on one side of one of the three groups of sliders away from the center of the circular plate. A cylinder is rotatably connected to the surface of one of the three groups of sliders. A card slot is opened on the surface of the cylinder. A limiting block is slidably connected to the surface of the concave-shaped frame. A second chute is opened on the side of the limiting block close to the cylinder. A clamping plate is slidably connected to the inner wall of the second chute. A third spring is fixed on the surface of the clamping plate, and the end of the third spring away from the clamping plate is fixed on the inner wall of the second chute. A fourth spring is fixed on the side of the limiting block away from the clamping plate, and the end of the fourth spring away from the limiting block is fixed on the inner surface of the concave-shaped frame. When the surface of the arc-shaped clamping plate fits the surface of the workpiece, continue to rotate the bolt clockwise, the stabilizing rod abuts against the inclined surface of the limiting block, driving the limiting block and the clamping plate to move closer to the cylinder. The side of the clamping plate away from the inclined surface abuts against the inner wall of the card slot, thereby limiting the cylinder and the bolt and preventing the bolt from continuing to rotate.

[0007] Preferably, the circular plate is fixed on the surface of the moving plate. A first chute is provided inside the circular plate. A slider is slidably connected to the inner wall of the first chute. Grooves are provided at both ends of the slider. A linkage plate is attached to the inner wall of the groove. A first spring is fixed on the surface of the linkage plate. The end of the first spring away from the linkage plate is fixed on the inner wall of the groove. A second spring is fixed on the side of the slider close to the center of the circular plate. An arc-shaped clamping plate is fixed at the end of the second spring away from the slider. A stabilizing rod is fixed on the side of the arc-shaped clamping plate close to the slider. The end of the stabilizing rod away from the arc-shaped clamping plate penetrates the slider, and the stabilizing rod is slidably connected to the slider. A bolt is fixed at the end of the cylinder away from the slider. The end of the bolt away from the cylinder penetrates the concave frame and the circular plate, and the bolt is threadedly connected to the circular plate. When the bolt is rotated forward, the slider moves inward, driving the arc-shaped clamping plate to move inward synchronously to clamp the workpiece. When the bolt is rotated in reverse, the cylinder rotates in reverse, and the inner wall of the card slot abuts against the inclined surface of the clamping plate, causing the clamping plate to enter the second chute, which will not affect the normal reverse rotation of the bolt. At this time, the workpiece is released.

[0008] Preferably, a threaded rod is rotatably connected to the inner wall of the operating table. A threaded plate penetrates the threaded rod, and the threaded plate is threadedly connected to the threaded rod.

[0009] Preferably, three sets of the first chutes and the linkage plates are provided, and the three sets of the first chutes and the linkage plates are circumferentially arranged around the center of the circular plate, which can enable the slider and the arc-shaped clamping plate to move radially synchronously.

[0010] Preferably, the side of the limiting block away from the cylinder is provided with an inclined surface. When being abutted, the limiting block can drive the clamping plate to move close to the cylinder.

[0011] Preferably, the side of the clamping plate away from the limiting block is provided with an inclined surface. When being abutted, the clamping plate can enter the second chute, which does not affect the reverse rotation of the bolt.

The stabilizing rod touches the inclined surface of the limiting block, driving the limiting block and the clamping plate to move closer to the cylinder. The clamping plate will enter the second chute, and the side of the clamping plate away from the inclined surface touches the inner wall of the card slot, thereby limiting the cylinder and the bolt, preventing the operator from continuing to rotate the bolt, and preventing the excessive clamping force caused by the operator not stopping rotating the bolt in time, which may lead to workpiece deformation or breakage.

[0014] 2. The clamping device with anti-bouncing function, through the provided clamping component, rotate the bolt forward, and the slider moves inward.

[0022] Such as Figures 1-6As shown, the utility model provides a technical solution: a clamping device with an anti-bounce function, including an operating table 1, a movable plate 4 is slidably connected to the top of the operating table 1, and a clamping component 6 and a protective component 7 are provided on the surface of the movable plate 4. The clamping component 6 includes: a circular plate 60, a slide groove 61, a slider 62, a groove 63, a linkage plate 64, a spring 1 65, a stabilizing rod 66, an arc-shaped clamping plate 67, a spring 2 68, and a bolt 69. The slider 62 is provided in three groups, and the three groups of sliders 62 are all arranged in a circular array with the center of the circular plate 60 as the axis center. The protective component 7 includes: a concave frame 70, a cylinder 71, a slot 72, a limit block 73, a slide groove 2 74, a clamping plate 75, a spring 3 76, and a spring 4 77.

[0023] The concave frame 70 is fixed to one side of the three groups of sliders 62, one of which is away from the center of the circular plate 60. The surface of one group of the three groups of sliders 62 is rotatably connected to a cylinder 71. A slot 72 is provided on the surface of the cylinder 71. The surface of the concave frame 70 is slidably connected to a limit block 73. A second slide groove 74 is provided on the side of the limit block 73 close to the cylinder 71. A card plate 75 is slidably connected to the inner wall of the second slide groove 74. A spring 3 76 is fixed to the surface of the card plate 75. The end of the spring 3 76 away from the card plate 75 is fixed to the inner wall of the second slide groove 74. A spring 4 77 is fixed to the side of the limit block 73 away from the card plate 75. The end of 7 away from the limit block 73 is fixed to the inner surface of the concave frame 70. When the surface of the arc clamping plate 67 is in contact with the surface of the workpiece, the bolt 69 continues to rotate forward, and the stabilizing rod 66 exposes the slider 62 and contacts the inclined surface of the limit block 73, driving the limit block 73 and the clamping plate 75 to move closer to the cylinder 71. The clamping plate 75 will enter the second slide groove 74, and the side of the clamping plate 75 away from the inclined surface will contact the inner wall of the clamping groove 72, thereby limiting the cylinder 71 and the bolt 69, so that the person cannot continue to rotate the bolt 69, which can prevent the person from not stopping the rotation of the bolt 69 in time and causing the clamping force to be too large, resulting in deformation or breakage of the workpiece.

[0024] The circular plate 60 is fixed on the surface of the moving plate 4. A first chute 61 is provided inside the circular plate 60. A slider 62 is slidably connected to the inner wall of the first chute 61. Grooves 63 are provided at both ends of the slider 62. A linkage plate 64 is attached to the inner wall of the groove 63. A first spring 65 is fixed on the surface of the linkage plate 64. One end of the first spring 65 away from the linkage plate 64 is fixed on the inner wall of the groove 63. A second spring 68 is fixed on the side of the slider 62 close to the center of the circular plate 60. An arc-shaped clamping plate 67 is fixed at one end of the second spring 68 away from the slider 62. A stabilizing rod 66 is fixed on the side of the arc-shaped clamping plate 67 close to the slider 62. One end of the stabilizing rod 66 away from the arc-shaped clamping plate 67 penetrates the slider 62, and the stabilizing rod 66 is slidably connected to the slider 62. A bolt 69 is fixed at one end of the cylinder 71 away from the slider 62. One end of the bolt 69 away from the cylinder 71 penetrates the concave frame 70 and the circular plate 60, and the bolt 69 is threadedly connected to the circular plate 60. When the bolt 69 is rotated forward, the slider 62 moves inward. Through the first chute 61 and the linkage plate 64, the three sliders 62 move inward synchronously. Through the stabilizing rod 66 and the second spring 68, the arc-shaped clamping plate 67 is driven to move inward synchronously to clamp the workpiece. When the bolt 69 is rotated reversely, the cylinder 71 rotates reversely. The inner wall of the card slot 72 abuts against the inclined surface of the clamping plate 75, so that the clamping plate 75 enters the second chute 74 and does not affect the normal reverse rotation of the bolt 69. At this time, the workpiece is released.

[0025] A threaded rod 2 is rotatably connected to the inner wall of the operating table 1. A threaded plate 3 penetrates the threaded rod 2, and the threaded plate 3 is threadedly connected to the threaded rod 2. The top of the threaded plate 3 penetrates the operating table 1, and the threaded plate 3 is slidably connected to the operating table 1. A motor 5 is fixed on the surface of the operating table 1. The output shaft of the motor 5 penetrates the operating table 1, and the output shaft of the motor 5 is fixed to the surface of the threaded rod 2. When the motor 5 is rotated forward, the threaded plate 3 can drive the moving plate 4 and the circular plate 60 to approach each other, or when the motor 5 is rotated reversely, they can be made to move away from each other.

[0026] Both the first chute 61 and the linkage plate 64 are provided in three groups, and the three groups of the first chute 61 and the linkage plate 64 are circumferentially arranged around the center of the circular plate 60, so that the three sliders 62 can move radially synchronously. The side of the limit block 73 away from the cylinder 71 is provided with an inclined surface. When being abutted, the limit block 73 can move closer to the cylinder 71. The side of the clamping plate 75 away from the limit block 73 is provided with an inclined surface. When being abutted, the clamping plate 75 can enter the second chute 74.

[0027] When machining the required cylindrical mechanical parts, the workpiece can be placed between the sliders 62 at this time. Manually rotate the bolt 69 clockwise. At this time, the sliders 62 move inward. Through the first chute 61 and the linkage plate 64, the three sliders 62 move inward synchronously. Thus, through the stabilizing rod 66 and the second spring 68, the arc-shaped clamping plate 67 is driven to move inward synchronously, so as to clamp the workpiece. At this time, the operator continues to rotate the bolt 69 clockwise, and the second spring 68 is compressed. At the same time, the stabilizing rod 66 exposes the slider 62 and abuts against the inclined surface of the limit block 73, thereby driving the limit block 73 and the clamping plate 75 to move closer to the cylinder 71. When the bolt 69 is rotated, the cylinder 71 will be driven to rotate synchronously. When the surface of the clamping plate 75 abuts against the surface of the cylinder 71, the clamping plate 75 will enter the second chute 74 at this time. When the clamping plate 75 is parallel to the position of the clamping groove 72, the third spring 76 will drive the clamping plate 75 into the clamping groove 72. At this time, the side of the clamping plate 75 away from the inclined surface abuts against the inner wall of the clamping groove 72, so as to limit the cylinder 71 and the bolt 69, so that the operator cannot continue to rotate the bolt 69, which can prevent the operator from not stopping rotating the bolt 69 in time and causing excessive clamping force, resulting in workpiece deformation or breakage. At this time, the motor 5 can be started to rotate forward, so that the threaded rod 2 rotates to drive the threaded plate 3, the moving plate 4, and the circular plate 60 to approach, so that the workpieces are machined. When the machining is completed, the operator can rotate the bolt 69 counterclockwise. At this time, the cylinder 71 rotates counterclockwise, and the inner wall of the clamping groove 72 abuts against the inclined surface of the clamping plate 75, so that the clamping plate 75 enters the second chute 74, which will not affect the normal counterclockwise rotation of the bolt 69. At this time, the workpiece is loosened, and the motor 5 is started to rotate counterclockwise, so that the circular plates 60 move away from each other. At this time, the operator can take out the workpiece.

[0028] The above generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
