Description

Technical Field

[0001] The utility model belongs to the technical field of clamps, and in particular relates to a drilling clamp for a luggage drawbar. Background Art

[0002] Luggage is a general term for bags, which is a general term for various bags used to carry things. The luggage rod is an important component of luggage, which is convenient for dragging the luggage and plays an important role in improving the portability of luggage. Drilling is required in the process of producing and processing the rod. In order to avoid displacement during the processing, it is often necessary to use a clamp to fix the position of the rod.

[0003] There are still some problems with the clamps currently used. First, the clamping method of the current clamps is too single, and usually it can only clamp the pull rod in one direction. The pull rod will vibrate when drilling, and the vibration will cause the pull rod to shift in the direction where it cannot be clamped, thereby causing the drilling position to be skewed. In addition, the clamping force of the current clamps is not easy to control. Excessive clamping force can easily cause the pull rod to deform and dent, while too little clamping force can easily cause the pull rod to loosen. Utility Model Content

[0004] The utility model provides a bag drawbar drilling clamp, aiming to solve the problems that the current clamp has a single fixing point and the clamping force is difficult to control.

[0005] The utility model is implemented as follows: a luggage drawbar drilling fixture comprises a base plate; a bracket is installed on the surface of the base plate, an operating table is installed on the top of the bracket, a fixed plate is installed on the side of the operating table, a sliding groove is opened on the inner side of the fixed plate, and a limiting block is slidably embedded in the sliding groove, a notch is vertically opened on the surface of the limiting block and a support plate is slidably inserted, a movable clamping plate is installed on the top of the support plate, a fixed clamping plate is installed on the rear side of the upper surface of the fixed plate, the movable clamping plate and the fixed clamping plate are both arranged in an L shape, an electric cylinder is installed at the center of the upper surface of the base plate, the output shaft of the electric cylinder is hinged with a connecting rod, and the other end of the connecting rod is hingedly connected to the bottom of the support plate.

Two groups of gaskets are slidably embedded in the interior of the connecting rod. The two groups of sliding rods are respectively connected to the two groups of gaskets. The two groups of gaskets are connected by springs. A pressure sensor is installed at the connection between one group of gaskets and the sliding rod, and the pressure sensor is electrically connected to the starting switch of the electric cylinder.

[0008] Preferably, a groove is provided on the surface of the operating table, and an ash box is placed in the groove.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0018] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0019] The utility model provides a bag pull rod drilling fixture, such as Figure 1-3 As shown, it includes a bottom plate 1, a bracket 2 is installed on the surface of the bottom plate 1, an operating table 3 is installed on the top of the bracket 2, a fixed plate 4 is installed on the side of the operating table 3, a slide groove is opened on the inner side of the fixed plate 4, and a limit block 5 is slidably embedded in the slide groove, a notch is vertically opened on the surface of the limit block 5 and a support plate 6 is slidably inserted, a movable clamping plate 7 is installed on the top of the support plate 6, a fixed clamping plate 8 is installed on the rear side of the upper surface of the fixed plate 4, and the movable clamping plate 7 and the fixed clamping plate 8 are both set to L shape, an electric cylinder 9 is installed at the center of the upper surface of the bottom plate 1, and the output shaft of the electric cylinder 9 is hinged with a connecting rod 10, and the connecting rod 1 The other end of 0 is hingedly connected to the bottom of the support plate 6. When the device is in use, the pull rod can be placed on the upper surface of the two sets of movable clamping plates 7, and then the electric cylinder 9 is started to push upward. At this time, the connecting rod 10 pushes the support plate 6, and the connecting rod 10 generates an oblique upward thrust on the support plate 6. Under the action of the limit block 5, the movable clamping plate 7 can not only slide horizontally, but also be pushed upward, so that the movable clamping plate 7 and the fixed clamping plate 8 can cooperate to perform dual fixation of the pull rod in the horizontal and vertical directions. This setting can effectively improve the stability of the pull rod clamping, thereby facilitating the subsequent drilling work to be carried out more smoothly.

[0020] There are two groups of fixed plates 4, which are respectively located on the left and right sides of the operating table 3. Two groups of movable clamping plates 7 are symmetrically distributed with the operating table 3 as the center. A connecting plate 11 is installed on the top of the output shaft of the electric cylinder 9. Two groups of connecting rods 10 are respectively hinged on the left and right sides of the connecting plate 11. By providing two groups of movable clamping plates 7 and fixed clamping plates 8, the two groups of movable clamping plates 7 and fixed clamping plates 8 cooperate to fix the surface of the pull rod, and the drilling position is located between the two fixed positions. By setting up two fixed points, the problem of position displacement caused by vibration when drilling the pull rod can be effectively avoided.

[0021] The interior of the connecting rod 10 is set to be hollow and the upper and lower ends are slidably inserted with sliding rods 12. Two groups of gaskets 13 are embedded in the interior of the connecting rod 10. The two groups of sliding rods 12 are respectively connected to the two groups of gaskets 13, and the two groups of gaskets 13 are connected by springs 14. A pressure sensor 15 is installed at the connection between one group of gaskets 13 and the sliding rod 12. The pressure sensor 15 is electrically connected to the starting switch of the electric cylinder 9. By setting the spring 14 and the pressure sensor 15, since the pull rods of the luggage are all hollow rods, when the clamping force is too large, it is easy to cause the pull rod to deform and sink. Here, by setting the pressure sensor 15, the pressure between the spring 14 and the sliding rod 12 can be detected, and the pressure is transmitted to the switch of the electric cylinder 9 through an electrical signal. When the pressure reaches the set value, the electric cylinder 9 stops running, so as to ensure that the clamping force is always consistent each time, thereby avoiding the problem of deformation of the pull rod due to excessive clamping force and loosening of the pull rod due to insufficient clamping force.

[0022] A groove is provided on the surface of the operating table 3, and an ash box 16 is placed in the groove. By providing the ash box 16, the ash box 16 can centrally collect the dust generated when the pull rod is drilled.

[0023] Two groups of buttons 17 are installed on the surface of the base plate 1, and a foot pedal is installed on the upper end of the button 17. The two groups of buttons 17 are electrically connected to the switch of the electric cylinder 9. By providing the button 17, the opening and closing switch of the electric cylinder 9 is controlled by foot pedal, so that the staff can free their hands to clamp and drill the pull rod, thereby improving the convenience of the drilling work.

[0024] The surface of the vertical plate of the fixed clamping plate 8 is provided with a groove that is compatible with the width of the horizontal plate of the movable clamping plate 7. By providing the groove on the surface of the fixed clamping plate 8, when it is necessary to clamp a thinner pull rod, the movable clamping plate 7 is in contact with the fixed clamping plate 8 but the pull rod is not effectively clamped. The groove here allows the movable clamping plate 7 to continue to move in the horizontal direction, thereby ensuring the stable clamping of the clamp.
