Description

Technical Field

[0001] The utility model relates to the technical field of CNC processing equipment, in particular to a CNC processing equipment with an anti-deviation positioning structure. Background Art

[0002] CNC (computer numerical control) is short for computer numerical control. It is an automated machine tool equipped with a program control system that can logically process and decode programs specified by control codes or other symbolic instructions to enable the machine tool to operate and process parts. Its components include a main machine, a numerical control device, a drive device, auxiliary devices, and programming and other ancillary equipment. Announcement No. CN217619379U discloses CNC machining equipment, comprising a base plate, a machining equipment body disposed on the surface of the base plate, two fixed plates fixedly connected to the interior of the machining equipment body, an L-shaped door disposed on the outer surface of the machining equipment body, two slide rails symmetrically disposed on the top of the machining equipment body, and two pulleys fixedly connected to the inner top of the door. In the present invention, a movable telescopic mechanism, a connecting plate and a brush are provided, and a motor is used to drive a bidirectional screw to rotate. When the bidirectional screw rotates, it can drive the connecting sleeve to move relative to the slide rod, and at the same time, a multi-section electric push rod is opened. The multi-section electric push rod drives the brush on the connecting plate to clean the generated waste chips, eliminating the need for manual cleaning of waste chips, thereby improving the efficiency of cleaning waste chips, and making the cleaning more thorough. The operation process is more convenient and more practical. However, the above technology usually relies on a simple clamping mechanism to fix the workpiece during use. These clamping mechanisms are prone to workpiece offset or unstable position during long-term and high-intensity processing. Unstable clamping will also increase tool wear during processing, reduce the operating efficiency of the equipment, and increase production costs. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems raised in the above background technology.

[0004] The utility model adopts the following technical scheme: a CNC processing equipment with an anti-deviation positioning structure, comprising a workbench, a frame fixedly mounted on the surface of the workbench, a lifting cylinder fixedly mounted on the top of the frame, a lifting plate fixedly mounted on the output end of the lifting cylinder, a No. 3 motor provided at the bottom of the lifting plate, a drill rod fixedly mounted on the output end of the No. 3 motor, a frame fixedly mounted on the surface of the workbench, a clamping cylinder fixedly mounted on the side of the frame, a main splint fixedly mounted on the output end of the clamping cylinder, a No. 1 motor fixedly mounted on the top surface of the main splint, a bidirectional screw fixedly mounted on the output end of the No. 1 motor, an auxiliary splint threadedly connected to the surface of the bidirectional screw.

[0005] Preferably, a second motor is fixedly mounted to the bottom of the lifting platform, with a drive screw fixedly mounted to the output end of the second motor. A movable block is threadedly connected to the surface of the drive screw, and the third motor is mounted on the bottom of the movable block. Here, the second motor drives the movable block via the drive screw, thereby enabling the third motor to move along the lifting platform. This allows for precise adjustment of the position of the third motor and the drill rod, achieving flexible machining positioning and improving machining accuracy. Furthermore, this movable mechanism can effectively accommodate workpieces of varying sizes, increasing the versatility and applicability of the equipment.

[0006] Preferably, first limit blocks are fixedly mounted on both sides of the main plate, and first limit slots are defined on both sides of the interior of the frame, with the first limit blocks slidingly connected within the first limit slots. This effectively prevents the main plate from shifting during the clamping process, thereby ensuring stable positioning of the workpiece. The equipment can accurately maintain the workpiece's position during machining, improving machining quality and reducing machining errors caused by unstable clamping.

[0007] Preferably, the main plate has a second limiting groove formed on its surface, and the auxiliary plate has a second limiting block fixedly mounted on its side, the second limiting block slidingly connected within the second limiting groove. This helps maintain smooth movement of the auxiliary plate, further preventing workpiece displacement during clamping, ensuring machining accuracy, and making the clamping operation more stable and adaptable to workpieces of varying sizes and shapes.

[0008] Preferably, a guide rod is fixedly mounted on the surface of the lifting platform and slidably connected to the interior of the frame. This ensures precise and stable vertical movement of the lifting platform, avoids shaking or deflection during the lifting process, improves the processing accuracy of the equipment, ensures accurate positioning of the drill rod, and thus enhances the stability and processing effect of the entire CNC processing equipment.

[0009] Preferably, the workbench has a chip hole formed on its surface, a chip trough formed on its top, and a collection box slidably connected to the chip trough. This allows chips generated during machining to quickly pass through the chip hole and into the chip trough, keeping the workbench surface clean. This reduces the degradation of machining accuracy caused by chip accumulation, reduces the cleaning burden on operators, and improves the efficiency and safety of the equipment.

[0010] Preferably, the debris trough is located directly below the debris hole. Here, the debris generated during the processing can automatically fall and be collected in the box, which facilitates the centralized processing and cleaning of the debris, reduces the workload of manual cleaning, improves the automation level and cleaning efficiency of the equipment, and helps maintain the long-term stable operation of the equipment.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the utility model, the main splint is driven by the clamping cylinder and is responsible for the preliminary clamping and fixing of the workpiece. Through the cooperation of the No. 1 limit block and the No. 1 limit groove, the main splint can maintain precise linear motion during the clamping process. The auxiliary splint is adjusted by the bidirectional screw driven by the No. 1 motor. The auxiliary splint can not only be flexibly adjusted according to the size of the workpiece, but also closely combined with the No. 2 limit groove on the main splint through its own No. 2 limit block, further preventing the splint from shifting during operation, ensuring that the workpiece is fixed more firmly and accurately.

[0013] 2. In this utility model, the chip holes on the workbench surface can quickly discharge the generated chips into the chip trough below, preventing the accumulation of chips on the workbench and affecting the processing accuracy. The chip trough is slidably connected to the collection box, allowing the operator to easily collect the chips, reducing the frequency and difficulty of manual cleaning.
