Description

Technical Field

[0001] This utility model relates to the field of basin hole machine technology, and more specifically to a basin hole machine with a high-efficiency clamping structure. Background Technology

[0002] A basin hole drilling machine is a drilling device used to open holes in plate-shaped raw materials. Through a multi-axis drive system, it controls the punch head to penetrate the plate-shaped raw material to complete the hole opening process. Before processing the raw material, it needs to be positioned by the positioning mechanism on the machine tool. When positioning rectangular plate-shaped raw materials, it is difficult to achieve fast positioning of circular plate-shaped raw materials when positioning circular plates. It is necessary to change the clamping head. Therefore, it is necessary to design a basin hole drilling machine with an efficient clamping structure. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a basin hole machine with a high-efficiency clamping structure to solve the problems existing in the background art.

[0005] The driving mechanism includes a first through slot axially extending through the top of the worktable. A motor is fixedly mounted at the bottom of the worktable, and a lead screw is fixedly mounted at the output end of the motor. A nut sleeve is threaded onto the outer surface of the lead screw and slidably mounted inside the first through slot. A movable clamping piece is fixedly mounted at the top of the nut sleeve. A stationary clamping piece is fixedly mounted on the side of the stationary positioning table near the movable positioning table. A through slot is opened through the side of the movable positioning table near the stationary positioning table. The other ends of both the movable and stationary clamping pieces pass through the through slot. The stationary positioning table, movable positioning table, movable clamping piece, and stationary clamping piece form a rectangular positioning structure. When positioning circular and irregularly shaped workpieces, quick clamping and positioning can be completed by adjustment without changing the fixture, which facilitates subsequent processing operations.

[0006] Furthermore, telescopic flexible protective covers are fixedly installed on both sides of the inner wall of the first through groove. The other end of the telescopic flexible protective cover is connected to the outer surface of the nut sleeve. As the nut sleeve moves, it covers and shields the first through groove to prevent dust from adhering to the outer surface of the lead screw.

[0007] Furthermore, the top of the workbench is provided with a sliding groove along the axial direction, a slider is slidably installed inside the sliding groove, and a support rod is fixedly installed on the top of the slider. The top of the support rod is fixedly connected to the bottom of the moving clamp, thereby increasing the stability and strength of the moving clamp.

[0008] Furthermore, the contact surfaces between the stationary clamp and the material are designed with rounded chamfers, which facilitates the guidance of the raw material when it slides on the top of the stationary clamp.

Detailed Implementation

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0019] Example 1: Refer to Figure 1-4 This utility model provides a basin hole punching machine with a high-efficiency clamping structure, including a basin hole punching machine body 100. The basin hole punching machine body 100 includes a frame 110 and a worktable 111. The top of the worktable 111 is connected to a punching mechanism 112 through a multi-axis transmission mechanism such as a ball screw module or a linear motor module. The transmission mechanism drives the punching mechanism 112 to move along the X, Y, and Z axes to perform precise hole punching operations on the material. The top two sides of the top of the worktable 111 are respectively provided with an L-shaped static positioning platform 113 and a dynamic positioning platform 114. The static positioning platform 113 is fixedly connected to the top of the worktable 111.

[0020] The drive mechanism 200 includes a first through slot 211 axially extending through the top of the worktable 111. A motor 212 is fixedly mounted at the bottom of the worktable 111. A lead screw 213 is fixedly mounted at the output end of the motor 212. A nut sleeve 214 is threaded onto the outer surface of the lead screw 213. The nut sleeve 214 is slidably mounted inside the first through slot 211. A movable clamping piece 215 is fixedly mounted at the top of the nut sleeve 214. A stationary clamping piece 216 is fixedly mounted on the side of the stationary positioning table 113 near the movable positioning table 114. A through slot 210 extends through the side of the movable positioning table 114 near the stationary positioning table 113. The other ends of both the movable clamping piece 215 and the stationary clamping piece 216 extend through the through slot 210. The contact surfaces of the sheet 216 and the material have rounded chamfers at the corners. The clamping surfaces of the moving clamping sheet 215 and the stationary clamping sheet 216 that are close to each other are covered with rubber strips 221, and the outer surfaces of the rubber strips 221 are provided with toothed grooves. The top of the worktable 111 has a second through groove 218. The bottom of the worktable 111 is fixedly installed with a cylinder 219. The telescopic end of the cylinder 219 is fixedly installed with a connecting piece 220. The connecting piece 220 is slidably installed inside the second through groove 218. Its top is fixedly connected to the bottom of the moving positioning table 114. The top of the moving positioning table 114 and the top of the worktable 111 slide against each other. The cylinder 219 drives the moving positioning table 114 to slide along the surface of the worktable 111 through the connecting piece 220.

[0021] The working principle of Embodiment 1 of this utility model is as follows: The raw material is placed on the L-shaped inner stepped surface of the static positioning platform 113 and the moving positioning platform 114 for positioning. The driving cylinder 219 works to make the moving positioning platform 114 horizontally approach the static positioning platform 113. During this process, the moving clamp 215 and the static clamp 216 pass through the through groove 210 without causing interference. At this time, the moving positioning platform 114 and the static positioning platform 113 jointly complete the initial positioning of the material on both sides. The driving motor 212 works, and the nut sleeve 214 moves linearly on the lead screw 213, driving the moving clamp 215 to move horizontally, so that the moving clamp 215 and the static clamp 216 jointly clamp the material, forming a four-way positioning rectangular frame composed of the static positioning platform 113, the moving positioning platform 114, the moving clamp 215 and the static clamp 216. The punching mechanism 112 performs multi-axis hole opening operation under the drive of the transmission mechanism.

[0022] Example 2:

[0023] The difference between Embodiment 2 and Embodiment 1 is that: telescopic flexible protective covers 217 are fixedly installed on both sides of the inner wall of the first through groove 211, and the other end of the telescopic flexible protective cover 217 is connected to the outer surface of the nut sleeve 214. As the nut sleeve 214 moves, it covers and shields the first through groove 211. A sliding groove is opened along the axial direction at the top of the worktable 111. A slider is slidably installed inside the sliding groove, and a support rod 222 is fixedly installed on the top of the slider. The top of the support rod 222 is fixedly connected to the bottom of the movable clamp 215. During the movement of the nut sleeve 214, the telescopic flexible protective covers 217 on both sides extend and retract to adapt to shield the first through groove 211, preventing debris from passing through the first through groove 211 and adhering to the surface of the lead screw 213. During the movement of the movable clamp 215, the slider at the bottom of the support rod 222 slides in the sliding groove, increasing the stability of the mechanism.
