Background

Machining refers to a process of changing the physical dimensions or properties of a workpiece by a mechanical device. The difference in the machining method can be divided into cutting machining and pressing machining. The inside of the hole usually falls into scrap iron when the part is drilled and machined, burrs are remained on the inner wall of the hole sometimes, and therefore the hole is blocked, and other parts are inserted into the hole. It is therefore necessary to inspect the interior of the bore after the machining and drilling process for certain parts. Because the parts are produced in large batch, the traditional manual detection efficiency is lower when detection is carried out. Therefore, an experimental detection platform for machining with high detection efficiency is needed.

Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.

Examples

As shown in fig. 1 and 2, an experimental detection platform for machining includes a platform 1, and an instrument back plate 3 and a positioning assembly for limiting a position of a workpiece 11 to be measured are provided on the platform 1, the instrument back plate being perpendicular to the platform 1. A right-angle frame 13 is fixed on the side surface of the platform 1 through a plurality of first fixing bolts 14, so that the right-angle frame 13 and the platform 1 form a C shape. Instrument backplate 3 fixed connection is at the top of right-angle frame 13, be equipped with inserted bar 9 and cam 5 on the instrument backplate 3, the axial direction and the platform 1 mutually perpendicular of inserted bar 9, cam 5 rotates to be connected on instrument backplate 3, the one end of inserted bar 9 offsets with cam 5, the other end inserts under the promotion of cam 5 in the trompil of the work piece 11 that awaits measuring, the one end that inserted bar 9 and cam 5 offset is provided with arcwall face 10, be equipped with the locating part that is used for restricting the direction of motion of inserted bar 9 on the instrument backplate 3, still be equipped with on the instrument backplate 3 and order about inserted bar 9 to keep away from the reset assembly of the work piece 11 that awaits measuring and be used for driving cam 5 pivoted drive. The platform 1 can be fixed on the fixed frame 2 through the second fixing bolt 15, so that the whole can be detached.

The locating component comprises two limiting strips 12 which are arranged on the surface of the platform 1 and are parallel to each other, the distance between the two limiting strips 12 is equal to the width of the workpiece 11 to be tested, the height between the right-angle frame 13 and the platform 1 is not smaller than the height of the workpiece 11 to be tested, the vertical surface of the right-angle frame 13 is perpendicular to the limiting strips 12 to form three side surfaces of the locating component, and one end, far away from the right-angle frame 13, of the limiting strips 12 is not closed to form an inlet.

The locating part includes two rings 7 of fixed setting on instrument backplate 3, and inserted bar 9 passes the interior circle of two rings 7 simultaneously to restriction inserted bar 9's direction of motion, the interior circle of ring 7 and inserted bar 9 clearance fit. The reset assembly comprises a stop ring 16 which is convexly arranged on the upper part of the inserted rod 9, a spring 8 is further sleeved on the inserted rod 9, one end of the spring 8 is abutted against the stop ring 16, and the other end of the spring is abutted against a circular ring 7 which is arranged at the upper end of the instrument backboard 3. The driving assembly comprises a hand-operated wheel 4 which coaxially rotates with the cam 5, the hand-operated wheel 4 coaxially rotates with the cam 5 through a rotating shaft 6, and the hand-operated wheel is rotatably connected to the instrument back plate 3. Adopt hand wheel 4 to enable the staff better to feel the smoothness nature in the whole in-process that detects, if obvious not smooth feeling appears, explain this trompil jam.

Specifically, when the positioning device is used, the workpiece 11 to be measured is firstly clamped between the two limiting strips 12 from the inlet of the positioning assembly and is quickly pushed in until the workpiece 11 to be measured abuts against the right-angle frame 13, and the positioning of the workpiece 11 to be measured is completed. After the workpiece to be measured 11 is positioned, the position of the opening in the workpiece to be measured 11 is opposite to the position of the inserted rod 9, the hand-operated wheel 4 is shaken, the hand-operated wheel 4 drives the cam 5 to rotate through the rotating shaft 6, and the end part of the inserted rod 9 is abutted against the cam 5, so that the workpiece to be measured gradually moves downwards. After the inserting rod 9 moves downwards, the distance between the stop ring 16 and the circular ring 7 is reduced, so that the spring 8 is compressed, when the highest point of the stroke of the cam 5 is abutted against the end part of the inserting rod 9, the moving position of the inserting rod 9 reaches the lowest point, the inserting rod 9 is completely inserted into the opening of the workpiece 11 to be detected, and the detection of the opening is completed. After this point, the plunger 9 moves upward by the elastic force of the spring 8, and is held in a state of abutting against the cam 5. In the process, if the hand-operated wheel 4 cannot rotate continuously in the process of rotating, the blockage of the opening in the workpiece 11 to be measured is indicated, and if the whole rotating process is smooth, the opening of the workpiece 11 to be measured is better. When the whole detection process is finished, the inserted link 9 automatically restores to the highest point position state under the action of the elastic force of the spring 8.
