Abstract
Description
Technical Field
[0001] This utility model relates to the field of workpiece processing technology, and more specifically, to a clamping device with a positioning structure. Background Technology
[0002] In the manufacturing industry, when lifting or processing round workpieces, it is usually necessary to first effectively clamp the workpiece. Only after ensuring a stable clamping position can processing or lifting operations be performed. However, existing clamping tools are not only bulky and complex in structure, but also prone to insecure clamping during use, leading to the risk of workpiece slippage during processing or lifting. Furthermore, it is impossible to accurately determine whether the workpiece is properly clamped during the clamping process, thus posing certain risks to the operation.
[0003] A search revealed application CN202010123987.1, which discloses a workpiece clamping fixture, comprising a fixture body, a clamping mechanism, a positioning mechanism, and an indicating mechanism. The fixture body is mounted on a worktable, and has a circular through hole in the center that connects vertically. Multiple supports are evenly spaced circumferentially on the sidewalls of the fixture body. The clamping mechanism includes a drive assembly and jaws. Rotating the drive assembly left or right drives all the jaws to move towards or away from the central axis of the fixture body. When the jaws slide within the groove so that the insertion hole is directly below the through hole, the positioning mechanism can be inserted into the insertion hole. The indicating mechanism includes a hollow lamp holder tube, an indicator light, and a lighting component. One end of the lighting component is spaced apart from the indicator light, and the other end extends into the insertion hole of the jaw. When the positioning component descends, it illuminates the indicator light. This workpiece clamping fixture effectively clamps the workpiece and facilitates the determination of whether the workpiece is properly clamped, thus facilitating the next processing step.
[0004] However, the clamping mechanism in the prior art has different clamping effects on workpiece shells of different shapes. Its contact position is fixed, the fixing effect is unstable, and it is not convenient to install or remove the light-shielding lens. In addition, adjusting the two light-shielding positions requires adjusting them separately to the left and right, which is not convenient. Utility Model Content
[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a clamping device with a positioning structure.
[0006] To solve the above problems, the present invention adopts the following technical solution.

[0008] As a further description of the above technical solution: the adjustment mechanism includes two light-shielding plates, two positioning sleeves, two springs and a drive assembly. Both positioning sleeves are fixedly connected to the inside of the frame. One end of the light-shielding plate is slidably connected to the inside of the positioning sleeve and elastically connected to the inside of the positioning sleeve through the spring. The other side of the light-shielding plate passes through the frame and is slidably connected to the inside of the light-transmitting groove. The drive assembly is installed on one side of the two light-shielding plates and rotates with the frame.
[0009] As a further description of the above technical solution: the drive assembly includes a rotating rod, a gear, and two toothed plates. One end of the rotating rod passes through the outside of the frame and is rotatably connected thereto. The other end of the rotating rod is fixedly connected to the gear. The two toothed plates are respectively fixedly connected to the same side of the two light-shielding sheets, and the opposite sides of the two toothed plates are engaged with the gear.
[0010] As a further description of the above technical solution: the side clamping mechanism includes a fixed sleeve, a threaded rod, and an arc-shaped clamping piece. The fixed sleeve is fixedly installed on the frame. The outer side of the threaded rod is threadedly connected to the inside of the fixed sleeve. One end of the threaded rod is rotatably connected to the arc-shaped clamping piece, and the arc-shaped clamping piece clamps and fixes the end of the workpiece.
[0011] As a further description of the above technical solution: the clamping mechanism includes a fixed clamping plate, a movable clamping plate and an adjusting rod. The fixed clamping plate is fixedly connected to one side of the bottom of the frame, the movable clamping plate is slidably installed to the other side of the bottom of the frame, one end of the adjusting rod passes through the inside of the frame and is threadedly connected thereto, and the end of the adjusting rod located inside the frame is rotatably connected to the movable clamping plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;
[0022] Please see Figures 1-4 In this utility model, a clamping device with a positioning structure includes a frame 1, a light-transmitting groove 2 is provided inside the frame 1, side clamping mechanisms 3 are installed on both sides of the top of the frame 1, a clamping plate mechanism 4 is installed at the bottom of the frame 1, a light-shielding plate 5 is engaged between the clamping plate mechanism 4 and the frame 1, and an adjustment mechanism 6 is installed inside the frame 1, which cooperates with the light-transmitting groove 2.
[0023] In this invention, the frame 1 serves as the main body of the device. Two side clamping mechanisms 3 are used to clamp the end of the workpiece in a ring-shaped manner from both sides, achieving positioning and fixation. The clamping mechanism 4 is then opened to install the required type of light-shielding sheet 5. Next, the adjustment mechanism 6 is used to adjust the diameter of the light-transmitting groove 2, thereby adjusting the amount of light entering and the size of the irradiation spot. The adjustment mechanism 6 can be adjusted simultaneously on both sides, allowing light to pass through the center of the light-transmitting groove 2, maintaining coaxiality between the light and the end of the workpiece, facilitating workpiece adjustment. This invention achieves the advantages of better clamping and positioning adaptability, stable fixation, easy installation and removal of the light-shielding lens, and more convenient synchronous adjustment of the light-shielding part. It solves the problems of existing clamping mechanisms having inconsistent clamping effects on workpiece shells of different shapes, fixed contact positions, unstable fixation effects, inconvenient installation and removal of the light-shielding lens, and the need for separate left and right adjustments to adjust the two light-shielding positions, which is inconvenient.
[0024] Please see Figure 1 and Figure 2 The adjustment mechanism 6 includes two light-shielding plates 61, two positioning sleeves 62, two springs 63, and a drive assembly 64. The two positioning sleeves 62 are fixedly connected to the inside of the frame 1. One end of the light-shielding plate 61 is slidably connected to the inside of the positioning sleeve 62 and elastically connected to the inside of the positioning sleeve 62 through the spring 63. The other side of the light-shielding plate 61 passes through the frame 1 and is slidably connected to the inside of the light-transmitting groove 2. The drive assembly 64 is installed on one side of the two light-shielding plates 61 and rotates with the frame 1.
[0025] In this invention, the rotation drive assembly 64 synchronously drives the light-shielding plates 61 inside the two positioning sleeves 62 to slide relative to each other. When the two springs 63 separate and adjust the two light-shielding plates 61, it is more labor-saving and the operation is smoother. At the same time, the two synchronous light-shielding plates 61 adjust the size of the light-transmitting area of the light-transmitting groove 2, which is convenient to operate and can always keep the irradiated light coaxial with the end of the workpiece, resulting in higher irradiation accuracy.
[0026] Please see Figure 2 The drive assembly 64 includes a rotating rod 641, a gear 642, and two toothed plates 643. One end of the rotating rod 641 passes through the outside of the frame 1 and is rotatably connected thereto. The other end of the rotating rod 641 is fixedly connected to the gear 642. The two toothed plates 643 are respectively fixedly connected to the same side of the two light-shielding plates 5. The opposite sides of the two toothed plates 643 are engaged with the gear 642.
[0027] In this invention, the rotating rod 641 drives the gear 642 to rotate, and the gear 642 drives the two toothed plates 643 to move in a straight line relative to each other, so as to drive the two light-shielding plates 61 to move in a synchronous relative direction and achieve synchronous adjustment.
[0028] Please see Figure 1 and Figure 3 The side clamping mechanism 3 includes a fixed sleeve 31, a threaded rod 32, and an arc-shaped clamping piece 33. The fixed sleeve 31 is fixedly installed on the frame 1. The outer side of the threaded rod 32 is threadedly connected to the inside of the fixed sleeve 31. One end of the threaded rod 32 is rotatably connected to the arc-shaped clamping piece 33, which clamps and fixes the end of the workpiece.
[0029] In this invention, by rotating the threaded rod 32 along the inside of the fixed sleeve 31, the arc-shaped clamping piece 33 is driven to surround and clamp the end of the workpiece, thereby achieving good adaptability to the shape of the end of the workpiece.
[0030] Please see Figure 1 and Figure 3The clamping mechanism 4 includes a fixed clamping plate 41, a movable clamping plate 42, and an adjusting rod 43. The fixed clamping plate 41 is fixedly connected to one side of the bottom of the frame 1, and the movable clamping plate 42 is slidably installed to the other side of the bottom of the frame 1. One end of the adjusting rod 43 passes through the interior of the frame 1 and is threadedly connected thereto. The end of the adjusting rod 43 located inside the frame 1 is rotatably connected to the movable clamping plate 42.
[0031] In this utility model, the distance between the moving clamp 42 and the fixed clamp 41 is changed by rotating the adjusting rod 43 to drive the moving clamp 42 to run along the bottom of the frame 1. When the moving clamp 42 is far away, it is convenient to load and unload the light shield 5. Then, the moving clamp 42 is brought close to the fixed clamp 41 to realize the quick loading and unloading of the light shield 5.
[0032] Please see Figure 1 The side view of both the fixed clamping plate 41 and the movable clamping plate 42 is L-shaped.
[0033] In this invention, the L-shaped fixed clamping plate 41 and the movable clamping plate 42 achieve a better clamping and fixing effect on the light-shielding sheet 5.
[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
