Description

Technical Field

[0001] This utility model relates to a mistake-proofing device, specifically a mistake-proofing device for machining center production and processing, belonging to the field of machining center technology. Background Technology

[0002] When machining parts, the workpiece needs to be placed on the machining center's fixture. The fixture is used to clamp the workpiece before machining. A fixture is a device used in mechanical manufacturing to fix the workpiece in the correct position for operation or inspection. Broadly speaking, any device used to quickly, conveniently, and safely install the workpiece at any stage of the manufacturing process can be called a fixture. A fixture typically consists of positioning elements, clamping devices, and tool setting guide elements, used to determine the relative position of the tool and the workpiece or to guide the tool's direction.

[0003] An existing patent (publication number: CN208132507U) discloses a rapid clamping device for machining centers, which includes a mounting platform. A clamping mold is mounted on the mounting platform, and the clamping mold includes a mounting base for mounting the mold. Two fixed seats are symmetrically arranged on the mounting base, and movable clamps are symmetrically arranged on both sides of the mounting base. The movable clamps penetrate the mounting platform and are hinged to it. A driving device is movably connected between the bottoms of the symmetrically arranged movable clamps, causing the movable clamps to move closer to or away from the fixed seats to clamp or release the workpiece. It controls the movable clamps to clamp or release the workpiece through the driving device, resulting in a high degree of automation and improved production efficiency. The curved positioning protrusions can automatically guide and correct the clamping position of the workpiece, making correction quick and simple, ensuring machining quality, and further improving machining efficiency. However, in practical use, it lacks a foolproof function. If the workpiece is clamped in the wrong direction, it will lead to machining errors, resulting in poor applicability. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figures 1 to 5 As shown, a machining center production error prevention device includes a device base 1, two placement seats 2 are installed on the upper surface of the device base 1, and a workpiece 3 is installed on the upper end of each of the two placement seats 2. A positioning mechanism for positioning the workpiece 3 is provided above the device base 1, a clamping mechanism for clamping the workpiece 3 is provided at both ends of the device base 1, and a fixing mechanism for fixing is provided inside the device base 1.

[0026] The positioning mechanism includes a first electric cylinder 4, a fixing plate 41, a pressing plate 42, a hinge rod 43, a hinge member 44, and a fixing base 45. There are two first electric cylinders 4, and both first electric cylinders 4 are fixed to the top of the device base 1 by screws. The telescopic ends of both first electric cylinders 4 are fixed with fixing plates 41. A pressing plate 42 is connected to one side of the fixing plate 41, and a pressure sensor is fixed to the upper end of the pressing plate 42 by screws.

[0027] Furthermore, a hinge rod 43 is fixed inside the clamping plate 42. The hinge rod 43 passes through the interior of the fixed plate 41. The first electric cylinder 4 is started by the external PLC controller, which in turn drives the fixed plate 41 to move. With the cooperation of the hinge 44 and the fixed seat 45, the front end of the clamping plate 42 presses against the upper surface of the workpiece 3.

[0028] Furthermore, a hinge 44 is hinged to one side of the clamping plate 42, and a fixed seat 45 that is fixedly connected to the first electric cylinder 4 is hinged to the lower end of the hinge 44. A sensor is installed on the top of the clamping plate 42. When the workpiece 3 is placed correctly, the sensor can start the processing normally when it senses the object; if it is placed in the opposite direction and the sensor cannot sense the object, the processing center cannot be started.

[0029] Example 2

[0030] Improvements based on Example 1:

[0031] Furthermore, the clamping mechanism includes a mounting groove 5, a second electric cylinder 51, a third electric cylinder 52, a connector 53, a threaded hole 54, a clamping plate 55, and a fixing screw 56. There are two mounting grooves 5, both of which are located at both ends of the device base 1. The second electric cylinder 51 is fixed inside each of the two mounting grooves 5 by bolts. The third electric cylinder 52 is fixed to the lower surface of the device base 1 by bolts. The connector 53 is fixed to the telescopic end of the third electric cylinder 52. Through the second electric cylinder 51 installed in the mounting groove 5, one end of the workpiece 3 can be further clamped and fixed.

[0032] Furthermore, the upper surface of the connector 53 is provided with a threaded hole 54, and a clamping plate 55 is connected above the connector 53. A fixing screw 56 is installed inside the clamping plate 55, and the fixing screw 56 is threadedly connected to the threaded hole 54. When the third electric cylinder 52 is started, it drives the connector 53 to move vertically, thereby driving the clamping plate 55 to clamp the other end of the workpiece 3, thereby effectively reducing the displacement of the workpiece 3.

[0033] Furthermore, the fixing mechanism includes a mounting hole 6 and a fixing bolt 61. The mounting hole 6 is opened inside the device base 1, and the fixing bolt 61 is installed at the upper end of the mounting hole 6. The device base 1 can be fixed by using the fixing bolt 61 through the mounting hole 6 provided on the device base 1.

[0034] Working Principle: Before using this machining center to produce the error-proof device, first place the device base 1 in a suitable position. Through the mounting holes 6 on the device base 1, fixing bolts 61 can be used to fix the device base 1, effectively reducing the possibility of displacement. The workpiece 3 to be processed is placed on the placement seat 2 on the device base 1. The first electric cylinder 4 is started by the external PLC controller, which in turn drives the fixed plate 41 to move. With the cooperation of the hinge 44 and the fixed seat 45, the front end of the clamping plate 42 presses against the upper surface of the workpiece 3. The hinge rod 43 ensures the normal rotation of the clamping plate 42. A sensor is installed on the top of the clamping plate 42. When workpiece 3 is placed correctly, the processing can start normally when the sensor detects the object; if it is placed in the wrong direction and the sensor cannot detect the object, the processing center cannot start. At the same time, the second electric cylinder 51 installed in the mounting slot 5 can further clamp and fix one end of workpiece 3, and the third electric cylinder 52 is started to drive the connecting piece 53 to move vertically, thereby driving the clamping plate 55 to clamp the other end of workpiece 3, thus effectively reducing the displacement of workpiece 3 and improving stability. The clamping plate 55 can be disassembled by unscrewing the fixing screw 56 on the clamping plate 55 through the threaded hole 54 on the connecting piece 53, so as to facilitate the replacement of the clamping plate 55 and make it easy to clamp different workpieces 3.
