Description

Technical Field

[0001] This utility model belongs to the field of punching machine technology, specifically relating to a clamping device for punching machines. Background Technology

[0002] A drilling machine is a metal processing device mainly used to create holes in various materials. It can cut precise holes in workpieces such as metal, plastic, and wood using different methods such as drilling, punching, or laser. In production, a special clamping device is required to hold the workpiece in place.

[0003] Traditional devices mostly rely on lead screws to drive sliders to clamp workpieces. This is stable when processing standard parts, but its adaptability and clamping efficiency are insufficient for irregularly shaped parts. Secondly, when it is necessary to adjust the angle of the workpiece, the conventional approach requires multiple steps such as first unclamping, then adjusting the angle of the workpiece, and finally reclamping, which also affects the accuracy and consistency of workpiece positioning. Utility Model Content

[0004] In view of this, the present invention provides a clamping device for a drilling machine, which can satisfy the clamping and fixing of irregularly shaped parts through a limiting mechanism, and can also adaptively adjust according to different shapes of the workpiece to realize drilling operations at different angles, simplifying operation steps, improving work efficiency, and avoiding affecting the accuracy and consistency of workpiece positioning.

[0005] To solve the above-mentioned technical problems, this utility model provides a clamping device for a drilling machine, including a worktable and sliding plates symmetrically slidably connected to both ends of the worktable. The upper surface of each sliding plate is provided with a support plate, and the upper end of each support plate is rotatably connected with a rotating column. Rectangular blocks are slidably connected to the axis of the opposite inner ends of the two rotating columns. Clamping plates are provided on the opposite inner sides of the two rectangular blocks. Limiting mechanisms for limiting the workpiece are provided on the opposite inner sides of the two clamping plates. A driving component for driving the two sliding plates to move synchronously is also provided in the worktable. Adjusting components for adjusting the movement of the rectangular blocks are provided in each rotating column. That is, the corresponding support plates, rotating columns, rectangular blocks and clamping plates of the two sliding plates are driven to move synchronously towards the center, thereby realizing the clamping of the workpiece.

[0006] The limiting mechanism includes multiple sliding holes respectively set on the inner sides of the two clamping plates. Each sliding hole is slidably connected to a limiting post, and each sliding hole is equipped with a spring. The spring is fixedly connected to the limiting post located in the same sliding hole. That is, the limiting post corresponding to the workpiece will overcome the elastic force of the spring and retract into the sliding hole, while the limiting post at the edge of the workpiece will limit the workpiece to ensure that the workpiece will not deviate. At the same time, it can adaptively adjust according to the different shapes of the workpiece.

[0007] The drive assembly includes a bidirectional lead screw rotatably connected to the transverse axis of the worktable. The two ends of the bidirectional lead screw are respectively threaded to the screw holes provided at the lower ends of adjacent sliding plates on the same side. That is, when the bidirectional lead screw rotates, it drives the two sliding plates and their auxiliary mechanisms to move synchronously toward the center through the screw holes, thereby realizing synchronous driving of the sliding plates.

[0008] The adjusting component includes threaded rods rotatably connected to the opposite ends of the two rotating columns. Each rectangular block has a threaded hole near the side axis of each threaded rod, which is threaded to it. When the corresponding threaded rod is rotated, the rotation of the threaded rod drives the rectangular block, clamping plate, sliding hole, limiting post and spring to move through the threaded hole, thereby satisfying the clamping and fixing of irregular parts.

[0009] It also includes a limiting component, which is used to limit the rotation column on one side. The limiting component includes fixed blocks arranged longitudinally symmetrically on the upper edge of the sliding plate on one side. A rotating rod is rotatably connected between the opposite inner surfaces of the two fixed blocks. A limiting block is provided in the middle of the outer arc surface of the rotating rod. A circular plate is provided at the end of the rotating column near the rotating rod. Multiple limiting grooves that cooperate with the limiting blocks are provided at the outer end edge of the circular plate. That is, by adjusting the plate to swing the rotating rod and the limiting block, the limiting block is separated from the limiting groove. At this time, the angle of the workpiece is adjusted by the circular plate. After the adjustment is completed, the adjustment plate is operated in reverse so that the limiting block re-cooperates with the corresponding limiting groove, thereby limiting the workpiece with the adjusted angle, which greatly improves the range of workpiece piercing operation and realizes piercing operation at different angles.

[0010] The limiting assembly also includes an adjusting plate located at one end of the rotating rod. A locking bolt is threaded to the upper end of the adjusting plate. A U-shaped plate is located on the upper surface of the sliding plate near the adjusting plate. The upper end of the U-shaped plate has a socket that matches the locking bolt. That is, by rotating the locking bolt counterclockwise, the locking bolt is separated from the socket, releasing the locking state of the adjusting plate. After the adjustment is completed, the operation is reversed to make the locking bolt and the socket re-fit, thereby locking the adjusting plate and ensuring the stability of the engagement between the limiting block and the corresponding limiting groove.

[0011] The workbench has symmetrically distributed assembly plates at its lower four corners, which makes it convenient for workers to fix the workbench and its auxiliary mechanisms.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. First, based on the actual processing conditions of the workpiece, rotate the corresponding lead screw. The rotation of the lead screw drives the rectangular block, clamping plate, sliding hole, limiting post, and spring to move through the screw hole. Then, the relevant operator places the workpiece to be perforated between the two clamping plates and then rotates the double-acting lead screw. When the double-acting lead screw rotates, it drives the two sliding plates and their auxiliary mechanisms to move synchronously towards the center through the screw hole, thereby achieving clamping of the workpiece. During this process, the limiting post corresponding to the workpiece will overcome the elastic force of the spring and retract into the sliding hole, while the limiting post at the edge of the workpiece will limit the workpiece to ensure that the workpiece will not deviate. At the same time, it can adaptively adjust according to the different shapes of the workpiece, thereby meeting the clamping and fixing of irregular parts.

[0014] 2. When the workpiece needs to be rotated, simply turn the locking bolt counterclockwise to separate it from the insertion hole. Then, swing the rotating rod and the limiting block using the adjusting plate to separate the limiting block from the limiting groove. At this time, the circular plate drives the rotating column, rectangular block, clamping plate, and limiting column on that side to rotate synchronously. Since the two workpieces are limited by the limiting columns on both sides, when the clamping plate on one side rotates, it drives the rotating column, rectangular block, clamping plate, limiting column, and their auxiliary mechanisms on the other side to rotate synchronously. After the adjustment is completed, reverse the operation of the adjusting plate to make the limiting block re-fit with the corresponding limiting groove, thereby limiting the workpiece with the adjusted angle. This greatly improves the range of workpiece piercing operations, realizes piercing operations at different angles, improves work efficiency, and avoids affecting the accuracy and consistency of workpiece positioning.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0021] like Figure 1-4 As shown:

[0022] This embodiment provides a clamping device for a punching machine, including a worktable 100 and sliding plates 101 symmetrically slidably connected to both ends of the worktable 100. The worktable 100 provides a fixed support location for its auxiliary mechanisms. Both ends of the worktable 100 are provided with slide grooves for providing sliding support for the sliding plates 101. The upper surface of each sliding plate 101 is provided with a support plate 102, which provides sliding support for the support plate 102. The upper end of each support plate 102 is rotatably connected with a rotating column 103. The upper end of each support plate 102 is provided with a rotating hole for providing rotational support for the rotating column 103. The two rotating columns 103 slide at their respective inner ends. The worktable 100 is connected to a rectangular block 104. The inner end of the rotating column 103 is provided with a rectangular groove for providing sliding support for the rectangular block 104. The two rectangular blocks 104 are provided with clamping plates 105 on their opposite inner sides. The two sliding plates 101 drive the corresponding support plate 102, rotating column 103, rectangular block 104 and clamping plate 105 to move synchronously toward the center, thereby clamping the workpiece. The two clamping plates 105 are provided with limiting mechanisms for limiting the workpiece on their opposite inner sides. The worktable 100 is also provided with a drive assembly for driving the two sliding plates 101 to move synchronously. The rotating column 103 is provided with an adjusting component for adjusting the movement of the rectangular block 104.

[0023] The operator places the workpiece to be perforated between the two clamping plates 105, and then drives the corresponding support plates 102, rotating columns 103, rectangular blocks 104 and clamping plates 105 of the two sliding plates 101 to move synchronously toward the center, thereby achieving the clamping of the workpiece.

[0024] like Figure 1-4 As shown, the limiting mechanism includes multiple sliding holes 106 respectively disposed on the opposite inner surfaces of the two clamping plates 105. The sliding holes 106 are evenly distributed, and each of the multiple sliding holes 106 is slidably connected to a limiting post 107. The sliding holes 106 are used to provide sliding support for the limiting post 107. Each sliding hole 106 is provided with a spring 108, and the spring 108 is fixedly connected to the limiting post 107 located in the same sliding hole 106. The spring 108 is used to provide elastic force to the limiting post 107.

[0025] The corresponding limiting post 107 will retract into the sliding hole 106 against the elastic force of the spring 108, while the limiting post 107 at the edge of the workpiece will limit the workpiece to ensure that the workpiece will not deviate, and can also be adaptively adjusted according to the different shapes of the workpiece.

[0026] like Figure 1-4 As shown, the drive assembly includes a bidirectional lead screw 109 rotatably connected to the transverse axis of the worktable 100. The transverse axis of the worktable 100 is provided with a rotating hole 2 for providing rotational support for the bidirectional lead screw 109. The two ends of the bidirectional lead screw 109 are respectively threadedly connected to the screw holes provided at the lower end of the adjacent sliding plate 101 on the same side.

[0027] The relevant operators rotate the bidirectional lead screw 109. When the bidirectional lead screw 109 rotates, it drives the two sliding plates 101 and their auxiliary mechanisms to move synchronously toward the center through the screw hole, thereby realizing the synchronous drive of the sliding plates 101.

[0028] like Figure 1-2 As shown, the adjusting component includes threaded rods 110 rotatably connected to the opposite ends of two rotating columns 103. Each of the opposite ends of the two rotating columns 103 is provided with a rotating hole 3 for providing rotational support for the threaded rods 110. The rectangular block 104 is provided with a threaded hole near the side axis of each threaded rod 110, which is threadedly connected to it. Due to the threaded relationship between the threaded rods 110 and the threaded holes, the threaded rods 110 drive the rectangular block 104 and its auxiliary mechanism to move through the threaded holes when rotating.

[0029] According to the actual processing conditions of the workpiece, the corresponding screw rod 110 is rotated. The rotation of the screw rod 110 drives the rectangular block 104, clamping plate 105, sliding hole 106, limiting post 107 and spring 108 to move through the screw hole, thereby satisfying the clamping and fixing of irregular parts.

[0030] like Figure 1-4 As shown, it also includes a limiting component, which is used to limit the rotation column 103 on one side. The limiting component includes a fixing block 200 arranged longitudinally symmetrically at the edge of the upper surface of the sliding plate 101 on one side. A rotating rod 201 is rotatably connected between the opposite inner surfaces of the two fixing blocks 200. Each of the opposite inner surfaces of the two fixing blocks 200 is provided with a rotating hole for providing rotational support for the rotating rod 201. A limiting block 202 is provided in the middle of the outer arc surface of the rotating rod 201. The rotating rod 201 is used to provide rotational support for the limiting block 202. A circular plate 203 is provided at the end of the rotating column 103 near the rotating rod 201. A plurality of limiting grooves 204 that cooperate with the limiting block 202 are provided at the outer end edge of the circular plate 203. The limiting block 202 and the limiting grooves 204 cooperate to lock the circular plate 203 and its associated mechanism.

[0031] By adjusting the plate 205 to swing the rotating rod 201 and the limiting block 202, the limiting block 202 is separated from the limiting groove 204. At this time, the circular plate 203 drives the rotating column 103, rectangular block 104, clamping plate 105 and limiting column 107 on this side to rotate synchronously. Since the two workpieces are limited by the limiting columns 107 on both sides, when the clamping plate 105 on one side rotates, it drives the rotating column 103, rectangular block 104, clamping plate 105, limiting column 107 and their auxiliary mechanisms on the other side to rotate synchronously. After the adjustment is completed, the adjusting plate 205 is operated in the opposite direction, so that the limiting block 202 re-coordinates with the corresponding limiting groove 204, thereby limiting the workpiece with the adjusted angle. This greatly improves the range of workpiece piercing operations, realizes piercing operations at different angles, simplifies the operation steps, improves work efficiency, and avoids affecting the accuracy and consistency of workpiece positioning.

[0032] like Figure 1-3 As shown, the limiting assembly also includes an adjusting plate 205 disposed at one end of the rotating rod 201. The upper end of the adjusting plate 205 is threaded with a locking bolt 206. A U-shaped plate 207 is provided on the upper surface of the sliding plate 101 near the adjusting plate 205. The upper end of the U-shaped plate 207 is provided with an insertion hole that matches the locking bolt 206. The locking bolt 206 cooperates with the insertion hole to lock the adjusting plate 205 and its auxiliary mechanism.

[0033] Rotate the locking bolt 206 counterclockwise to separate it from the insertion hole, releasing the locking state of the adjusting plate 205. At this time, the circular plate 203 drives the rotating column 103, rectangular block 104, clamping plate 105 and limiting column 107 on this side to rotate synchronously. After the adjustment is completed, reverse the operation to make the locking bolt 206 re-engage with the insertion hole, thereby locking the adjusting plate 205.

[0034] The working principle of the clamping device for a drilling machine provided by this utility model is as follows: First, the operator places the workpiece to be drilled between two clamping plates 105, and then rotates the bidirectional lead screw 109. When the bidirectional lead screw 109 rotates, it drives the two sliding plates 101 and their auxiliary mechanisms to move synchronously towards the center through the screw hole, thereby clamping the workpiece. During this process, the limiting post 107 corresponding to the workpiece will overcome the elastic force of the spring 108 and retract into the sliding hole 106, while the limiting post 107 at the edge of the workpiece will clamp the workpiece. The limit switch ensures the workpiece will not shift and can adaptively adjust to different workpiece shapes. Depending on the actual machining conditions of the workpiece, the corresponding screw thread 110 is rotated. The rotation of the screw thread 110 drives the rectangular block 104, clamping plate 105, sliding hole 106, limit post 107, and spring 108 to move, thus satisfying the clamping and fixing of irregularly shaped parts. When the workpiece needs to be rotated, simply rotate the locking bolt 206 counterclockwise to disengage it from the insertion hole, and then the adjusting plate 205 swings and rotates. Rod 201 and limiting block 202 are used to separate limiting block 202 from limiting groove 204. At this time, the circular plate 203 drives the rotating column 103, rectangular block 104, clamping plate 105 and limiting column 107 on this side to rotate synchronously. Since the two workpieces are limited by the limiting columns 107 on both sides, when the clamping plate 105 on one side rotates, it drives the rotating column 103, rectangular block 104, clamping plate 105, limiting column 107 and their auxiliary mechanisms on the other side to rotate synchronously. After the adjustment is completed, the adjusting plate 205 is operated in the opposite direction to make the limiting block 202... 02 re-fits with the corresponding limiting groove 204, thereby adjusting the workpiece angle for limiting, greatly improving the range of workpiece piercing operations, realizing piercing operations at different angles, simplifying operation steps, improving work efficiency, and avoiding affecting the accuracy and consistency of workpiece positioning. After everything is ready, start the piercing machine to operate. After the piercing operation is completed, reverse the above steps, release the clamp on the workpiece, safely unload the processed workpiece, and then readjust the device as needed to adapt to the next workpiece of different size or shape.

[0035] like Figure 1-2 As shown, the lower four corners of the workbench 100 are provided with symmetrically distributed assembly plates, each with a round hole to facilitate the worker to fix the workbench 100 and its auxiliary mechanisms.

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
