Description

Technical Field

[0001] The utility model relates to the field of jigs, in particular to a plane calibration jig. Background Art

[0002] In the mold workpiece processing scenario, there are usually strict requirements for the workpiece processing angle to ensure the processing accuracy and ensure the final smooth assembly and use of the mold.

[0003] During the machining process, the surface to be machined of the workpiece needs to be swung to a completely horizontal state. However, for workpieces with more complex structures (such as push blocks), there are usually multiple surfaces at different angles. Therefore, the workpiece needs to be connected to the connecting rod, and then the connecting rod is pre-clamped by a fixture, and then placed on the machine tool. The measuring instrument is installed on the machine tool, and the workpiece is moved left and right, front and back through the machine tool worktable. If the pointer of the measuring instrument rotates within the tolerance range, it means that the surface to be machined of the workpiece meets the requirements of the machining preparation and is in a horizontal state. Otherwise, it is necessary to use a copper hammer to knock the connecting rod left and right, up and down, and then calibrate the table according to the direction of the pointer rotation. Repeat the debugging several times until the surface to be machined of the workpiece is adjusted to a horizontal state, and then the connecting rod is locked. For workpieces with more complex structures (such as double push rod push blocks, large push blocks, and inclined push blocks), the workpiece leveling operation will also become complicated and take a long time, thus affecting efficiency.

DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] When in use, the workpiece can be connected to the connecting rod 40, and then the adjusting component 30 is used to drive the matching seat 20 to move in the direction close to the clamping part 11, and the matching seat 20 and the clamping part 11 are used to pre-clamp the connecting rod 40, and then the first magnetic adsorption component 51 is magnetically adsorbed on the matching seat 20 and contacts the matching seat 20 through the first horizontal plane 57, and then the connecting rod 40 is adjusted to magnetically adsorb the surface to be processed of the workpiece on the second horizontal plane 58 of the second magnetic adsorption component 53, so that the surface to be processed of the workpiece can be quickly adjusted to a horizontal state with the help of the directional effect of the second horizontal plane 58 of the second magnetic adsorption component 53, so that the leveling operation of the workpiece can be quickly completed, and the leveled workpiece is subsequently locked. Therefore, the utility model provides a plane calibration fixture, which can quickly level the workpiece's surface to be processed by adopting a mounting seat 10, a matching seat 20, an adjustment component 30, a connecting rod 40 and a magnetic adsorption device 50, and by using the magnetic adsorption device 50 to combine a first magnetic adsorption component 51, a connecting seat 52 and a second magnetic adsorption component 53, thereby eliminating the calibration work, making the workpiece leveling operation simpler and faster, and saving adjustment time. Especially when it is used for workpieces with larger volumes and more complex push block surfaces, the more adjustment time is saved. For example, the leveling operation of the double push rod inclined push block only takes 15 seconds, without spending nearly 10 minutes on calibration, which can significantly improve efficiency.

The threaded adjustment rod is threadedly connected to the support portion 13. By adopting the above structure, it is convenient to make and form the mounting seat 10, so as to reduce the manufacturing cost of the mounting seat 10.
