Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and in particular to a clamping device for manufacturing mechanical and electrical equipment. Background Technology

[0002] Mechanical and electrical equipment requires drilling, cutting, grinding and other processing during manufacturing. Clamping devices are needed to hold and fix the equipment during processing. However, traditional positioning clamping devices have unstable clamping effects, and the workpiece is prone to shaking during processing, which affects the processing.

[0003] The prior art CN218284600U discloses a clamping device for manufacturing mechanical and electrical equipment, including a main body box and a clamping assembly. The clamping assembly is disposed inside the main body box and includes a trapezoidal block 1, a trapezoidal block 2, a connecting frame, a sliding rod, a slider, a guide post, a threaded post, a driven bevel gear, a driven bevel gear, a servo motor, a fixed sleeve, a sliding rod, and a spring. A slide rail is provided on the inner wall of the main body box. The trapezoidal block 2 is horizontally slidably disposed on the slide rail. The fixed sleeve is fixedly disposed inside the main body box. One end of the sliding rod is slidably disposed inside the fixed sleeve, and the other end of the sliding rod is fixedly connected to the trapezoidal block 2. The spring is sleeved on the sliding rod. A slide groove is provided on the inner wall of the main body box. The slider is vertically slidably disposed in the slide groove, and the sliding rod is fixedly disposed on the slider. In use, place the workpiece on the top outer wall of the main body box, then start the servo motor. The servo motor drives the active bevel gear to rotate, which in turn drives the passive bevel gear to rotate. The passive bevel gear drives the threaded column to move downwards, which in turn drives the sliding rod, connecting frame, and trapezoidal block one to move downwards. At this time, trapezoidal block one will drive trapezoidal block two to move inwards simultaneously, and trapezoidal block two will drive the clamping plate to move inwards simultaneously. When the clamping plate contacts the workpiece, the workpiece can be clamped securely. After the operation is completed, start the servo motor in reverse. At this time, the spring will drive trapezoidal block two to move to both sides, and trapezoidal block two will drive the clamping plate to move outwards, at which point the workpiece can be removed.

[0004] During the clamping process, the above-mentioned device can only clamp the left and right sides of the workpiece, resulting in poor workpiece fixation and easy displacement of the workpiece in other directions. Utility Model Content

[0005] The purpose of this utility model is to provide a clamping device for manufacturing mechanical and electrical equipment, which solves the problem that the existing clamping device for manufacturing mechanical and electrical equipment can only clamp the left and right sides of the workpiece, resulting in poor workpiece fixation and easy workpiece displacement in other directions.

[0006] To achieve the above objectives, this utility model provides a clamping device for manufacturing mechanical and electrical equipment, including a worktable and a rotary table. The rotary table is rotatably mounted on the worktable, and the device also includes a clamping assembly. The clamping assembly includes a movable shell, a clamping seat, a return spring, a movable shaft, a clamping plate, a limiting member, and a driving member. The movable shell is slidably connected to the rotary table and located on one side of the rotary table. The clamping seat is slidably connected to the movable shell and located inside the movable shell. The two ends of the return spring are respectively connected to the clamping seat and the movable shell, and the return spring is located inside the movable shell. The clamping seat has a driving groove. The clamping plate is slidably connected to the movable shell and disposed on the movable shell. The movable shaft is fixedly connected to the clamping plate and slidably connected to the clamping seat, and is located inside the driving groove. The limiting member is disposed on the clamping seat, and the driving member is disposed on the rotary table.

[0007] The movable shell has a first limiting groove, which is disposed inside the movable shell; the clamping seat has a first limiting protrusion, which is located on the side of the clamping seat near the first limiting groove, and the first limiting protrusion cooperates with the first limiting groove.

[0008] The movable shell has a second limiting groove, which is disposed inside the movable shell; the clamping plate has a second limiting protrusion, which is disposed on the side of the clamping plate near the second limiting groove, and the second limiting protrusion cooperates with the second limiting groove.

[0009] The limiting component includes a vertical plate, a limiting spring, and a limiting plate. The vertical plate is fixedly connected to the clamping seat and is located on one side of the clamping seat. The limiting plate is slidably connected to the vertical plate and is located on one side of the vertical plate. The two ends of the limiting spring are respectively connected to the vertical plate and the limiting plate, and the limiting spring is located inside the vertical plate.

[0010] The clamping device for manufacturing mechanical and electrical equipment further includes a support base and a ball bearing. The support base is fixedly connected to the worktable and is located inside the worktable. The ball bearing is rotatably connected to the support base and contacts the rotary table, and is located on the side of the support base closer to the rotary table.

[0011] This utility model discloses a clamping device for manufacturing mechanical and electrical equipment. In use, the workpiece to be processed is placed on the rotary table and positioned between two clamping seats. The drive motor is then activated, driving the bidirectional screw to rotate. The bidirectional screw drives two threaded sleeves to move, which in turn move the movable housing, bringing the two movable housings closer together. The movable housings then move the corresponding clamping seats, bringing them into contact with the left and right sides of the workpiece. The drive mechanism continues to drive the movable housings, causing them to move the clamping plates and the moving shaft. Since the clamping seats stop moving when in contact with the workpiece, the moving shaft and clamping plates move relative to the clamping seats. The moving shaft moves back and forth along the drive groove, further moving the clamping plates, bringing the two clamping plates on the clamping seats closer together and clamping the front and rear sides of the workpiece. At this point, the left and right sides of the workpiece are clamped and fixed by the two clamping seats, while the front and rear sides are clamped and fixed by the clamping plates, thereby improving the fixation effect on the workpiece and preventing workpiece displacement during processing, which would affect the processing.

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

Figure 2 This is a structural diagram of the driving component. Figure 3 This is a structural diagram of the limiting component.

[0021] This utility model provides a clamping device for manufacturing mechanical and electrical equipment, including a worktable 101, a rotary table 102, and a clamping assembly 103. The clamping assembly 103 includes a movable shell 104, a clamping seat 105, a return spring 106, a movable shaft 107, a clamping plate 108, a limiting member 109, a driving member 110, a support seat 118, and a ball bearing 119. The movable shell 104 has a first limiting groove 111 and a second limiting groove 113. The clamping seat 105 has a first limiting protrusion 112, and the clamping plate 108 has a second limiting protrusion 114. The driving member 110 drives the two movable shells 104 to interact. The two clamping seats 105 move closer together, and stop moving when they contact the side of the workpiece. Meanwhile, the moving shell 104 continues to move the moving shaft 107 and the clamping plate 108, so that the moving shaft 107 moves along the drive groove 120 on the clamping seat 105, thereby moving the clamping plate 108. This allows the two clamping plates 108 to contact the front and rear sides of the workpiece, thus improving the fixation effect on the workpiece. It can be understood that the above solution can be used to prevent the workpiece from shifting during processing, and can also be used to improve the stability of the rotary table 102.

[0022] In this specific embodiment, the rotary table 102 is rotatably mounted on the worktable 101. A rotary motor 121 is also installed inside the worktable 101. The output end of the rotary motor 121 is connected to the rotary table 102. The rotary motor 121 drives the rotary table 102 to rotate, thereby driving the workpiece above it to rotate, thus facilitating the processing of the workpiece from different angles.

[0023] The movable housing 104 is slidably connected to the rotating table 102 and located on one side of the rotating table 102. The clamping seat 105 is slidably connected to the movable housing 104 and located inside the movable housing 104. The two ends of the return spring 106 are respectively connected to the clamping seat 105 and the movable housing 104, and the return spring 106 is located inside the movable housing 104. The clamping seat 105 has a drive groove 120. The clamping plate 108 is slidably connected to the movable housing 104 and is disposed on the movable housing 104. The movable shaft 107 is fixedly connected to the clamping plate 108 and slidably connected to the clamping seat 105, and is located inside the drive groove 120. The limiting member 109 is disposed on the clamping seat 105. The drive member 110 is disposed on the rotating table 102. Two clamping assemblies 103 are provided and are respectively located on the rotating table 102. On both sides of the rotary table 102, a clamping seat 105 is provided with two moving shafts 107 and two clamping plates 108. The driving component 110 includes a driving motor 122, a bidirectional screw 123 and two threaded sleeves 124. The bidirectional screw 123 is rotatably installed inside the rotary table 102. The threaded sleeves 124 are threaded onto the bidirectional screw 123 and fixedly connected to the moving shell 104. The driving motor 122 is installed on one side of the rotary table 102. The output end of the driving motor 122 is connected to the bidirectional screw 123. The limiting component 109 is used to limit the vertical movement of the workpiece. A clamping seat 105 is provided with two driving grooves 120. The two driving grooves 120 are inclined. By the elasticity of the return spring 106, the clamping seat 105 extends out of the moving shell 104 when no force is applied.

[0024] In use, the workpiece to be processed is placed on the rotary table 102, and positioned between the two clamping seats 105. Then, the drive motor 122 is started to drive the bidirectional screw 123 to rotate. The bidirectional screw 123 drives the two threaded sleeves 124 to move. The threaded sleeves 124 drive the movable housing 104 to move, thereby bringing the two movable housings 104 closer together. The movable housings 104 drive the corresponding clamping seats 105 to move, so that the two clamping seats 105 contact the left and right sides of the workpiece. Then, the drive member 110 continues to drive the movable housings 104 to move, so that the movable housings 104 drive the clamping plate 108 and the movable housing 105 to move. As the moving shaft 107 moves, the clamping seat 105 stops moving when it contacts the workpiece. This causes the moving shaft 107 and the clamping plate 108 to move relative to the clamping seat 105. The moving shaft 107 moves back and forth along the drive groove 120, which in turn drives the clamping plate 108 to move. This allows the two clamping plates 108 on the clamping seat 105 to come closer together and clamp the front and rear sides of the workpiece. At this time, the left and right sides of the workpiece are clamped and fixed by the two clamping seats 105, while the front and rear sides are clamped and fixed by the clamping plates 108. This improves the fixation effect on the workpiece and prevents the workpiece from shifting during processing, which would affect the processing.

[0025] Secondly, the first limiting groove 111 is disposed inside the movable shell 104; the clamping seat 105 has a first limiting protrusion 112, which is located on the side of the clamping seat 105 near the first limiting groove 111, and the first limiting protrusion 112 cooperates with the first limiting groove 111; there are two of each of the first limiting protrusion 112 and the first limiting groove 111, which are respectively located on both sides of the clamping seat 105. The movement of the first limiting protrusion 112 is limited by the first limiting groove 111, thereby limiting the movement of the clamping seat 105, so that the clamping seat 105 can only move along the length direction of the first limiting groove 111, thereby improving the stability of the clamping seat 105 when it moves.

[0026] Meanwhile, the second limiting groove 113 is disposed inside the movable shell 104; the second limiting protrusion 114 is disposed on the side of the clamping plate 108 near the second limiting groove 113, and the second limiting protrusion 114 cooperates with the second limiting groove 113; the movement of the second limiting protrusion 114 is limited by the second limiting groove 113, thereby limiting the movement of the clamping plate 108, so that the clamping plate 108 can only move along the length direction of the second limiting groove 113, thereby improving the stability of the clamping plate 108 when it moves.

[0027] Additionally, the vertical plate 115 is fixedly connected to the clamping seat 105 and located on one side of the clamping seat 105; the limiting plate 117 is slidably connected to the vertical plate 115 and located on one side of the vertical plate 115; the two ends of the limiting spring 116 are respectively connected to the vertical plate 115 and the limiting plate 117, and the limiting spring 116 is located inside the vertical plate 115; a plurality of limiting plates 117 are provided on one vertical plate 115, and the plurality of limiting plates 117 are arranged along the height direction of the vertical plate 115, and a plurality of limiting plates 117 are provided on one limiting plate 117. The limiting spring 116 drives the limiting plate 117 to extend out of the vertical plate 115. When the clamping seat 105 moves, it drives the vertical plate 115 and the limiting plate 117 to move. When the vertical plate 115 contacts the workpiece surface, under pressure, the limiting plate 117 in contact with the workpiece retracts into the vertical plate 115, while the limiting plate 117 not in contact with the workpiece remains extended. At this time, the limiting plate 117 located above the workpiece can limit the vertical movement of the workpiece, further improving the stability of the workpiece fixation.

[0028] Finally, the support base 118 is fixedly connected to the worktable 101 and is located inside the worktable 101; the ball bearing 119 is rotatably connected to the support base 118 and contacts the rotary table 102, and is located on the side of the support base 118 close to the rotary table 102; multiple balls bearing 119 are provided and are evenly distributed on the support base 118, supporting the rotary table 102 through the support base 118 and the ball bearing 119, and reducing the friction between the rotary table 102 and the ball bearing 119 through the rotation of the ball bearing 119.

[0029] When using the clamping device for manufacturing mechanical and electrical equipment according to this utility model, the driving member 110 drives the two movable shells 104 to move closer to each other, thereby driving the two clamping seats 105 to move closer to each other, so that the two clamping seats 105 can contact the left and right sides of the workpiece. Then, the movable shells 104 continue to move and drive the movable shaft 107 and the clamping plate 108 to move, so that the movable shaft 107 moves along the driving groove 120, thereby driving the clamping plate 108 to move, so that the two clamping plates 108 can contact the front and rear sides of the workpiece. At this time, the left and right movement of the workpiece is limited by the clamping seats 105, while the front and rear movement is limited by the clamping plate 108. At the same time, the limiting plate 117 can further limit the vertical movement of the workpiece, thereby improving the fixing effect of the workpiece and avoiding the problem of workpiece displacement during processing.

[0030] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
