DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] The workpiece 100 is a car radiator mask. The workpiece 100 is provided with a hanging ear 101 corresponding to the workpiece vertical positioning component 2 and a hanging hole corresponding to the horizontal positioning rod 7. When the workpiece 100 is placed in the molding mechanism 3, the hanging ear 101 needs to be inserted into the workpiece vertical positioning component 2, and the hanging hole needs to be inserted into the horizontal positioning rod 7, but these two actions cannot be completed at the same time. The usual operation is to first insert the hanging ear 101 into the workpiece vertical positioning component 2, and then insert the horizontal positioning rod 7 into the hanging hole (not shown in the figure). The structure of the hanging hole can be similar to that of the hanging ear 101, that is, an ear-shaped component with a round hole in the middle. During the positioning process of the workpiece 100 from high to low, the horizontal positioning rod 7 will interfere, resulting in failure to be normally inserted into the hanging hole of the workpiece. In this embodiment, in order to avoid this interference, the double-track positioning assembly 5 is movably connected to the base 1. The double-track positioning assembly 5 is first moved away from the flip arm clamping assembly 4 to make the horizontal positioning rod 7 away from the flip arm clamping assembly 4. After the workpiece is inserted into the horizontal positioning rod 7, the double-track positioning assembly 5 is moved close to the flip arm clamping assembly 4 to insert the horizontal positioning rod 7 into the hanging hole.

[0031] Specifically, the dual-track positioning assembly 5 includes a plurality of independent dual-track body parts 8 arranged in a straight line, and the connecting line of the upper surfaces of the plurality of dual-track body parts 8 is a smooth arc, or it can also be understood that the upper surfaces of the plurality of dual-track body parts 8 are connected to each other to form a smooth arc surface, which is used to match the bottom shape of the workpiece 100.

[0032] The double-track body 8 is movably connected to the base 1 and can be moved closer to or farther from the flip arm clamping assembly 4. A horizontal positioning rod 7 is respectively provided on the two double-track body 8 at both ends. Those skilled in the art should understand that the horizontal positioning rod 7 can be screwed, welded, or clamped to the double-track body 8, and the horizontal positioning rod 7 is horizontally arranged.

[0033] Those skilled in the art should also understand that horizontal positioning rods 7 may also be provided on other double-track body parts 8, while the present embodiment provides horizontal positioning rods 7 at both ends of the double-track positioning assembly 5 in order to ensure that both ends of the workpiece 100 are in the same horizontal plane when positioned.

[0034] Combination Figure 3 and Figure 4 As shown, the workpiece vertical positioning assembly 2 includes a plurality of vertical positioning seats 32 fixed on the base 1 and arranged vertically, and a vertical positioning rod 33 is provided at the end of the vertical positioning seat 32. Preferably, the bottoms of the plurality of vertical positioning rods 33 are on the same plane, that is, the horizontal heights of the connection between the vertical positioning rod 33 and the vertical positioning seat 32 are the same, and the two horizontal positioning rods 7 are also on the same plane, and the vertical positioning rod 33 is perpendicular to the horizontal positioning rod 7.

[0035] The combination of the vertical positioning rod 33 and the horizontal positioning rod 7 ensures that the workpiece is at the same level in the vertical direction and the horizontal direction during the placement process, thereby avoiding system errors caused by improper placement of the workpiece.

[0036] For example Figure 1 As shown, a side wall positioning assembly 6 is provided on the base 1 and on both sides of the double track positioning assembly 5, and the side wall positioning assembly 6 includes a side wall positioning strip 26 fixedly connected to the base 1. Two horizontal positioning rods 7 are respectively located on two lower molded parts 11 at both ends of the double track positioning assembly 5.

[0041] The bottom of the workpiece 100 is pressed against the workpiece bottom positioning groove 12, and the lower detection block 13 slides along the slide groove 17. When the end of the lower detection block 13 abuts against the bottom of the workpiece, it stops moving to detect whether the lower positioning hole 18 and the lower detection hole 19 are aligned one by one. If aligned, it can be determined that the bottom size of the workpiece 100 meets the requirements. Otherwise, the bottom size of the workpiece 100 has deviations and does not meet the requirements. During the detection process, the pin can also be inserted into the lower positioning hole 18 to determine whether it is aligned by whether it can be normally inserted into the lower detection hole 19. The sizes of the pin, the lower positioning hole 18 and the lower detection hole 19 are consistent.

[0045] A dial indicator can be inserted into the positioning bar punching hole 29 and the stopper punching hole 28 to perform a punching test on the dimensions of the side wall and the edge of the side wall of the workpiece 100 .

[0046] A plurality of fixed-point detection columns 30 are provided on the base 1 and between the double-track positioning assembly 5 and the flip arm clamping assembly 4. The fixed-point detection column 30 is movably connected with a fixed-point detection rod 31 which can reciprocate in the horizontal direction so as to approach or move away from the double-track positioning assembly 5. A spring is sleeved on the fixed-point detection rod 31, and both ends of the spring are fixedly connected to the fixed-point detection column 30 and the fixed-point detection rod 31. The fixed-point detection rod 31 is inserted into the fixed-point detection column 30 and movably connected to the fixed-point detection column 30.

A detection hole corresponding to the position and size of the fixed-point detection rod 31 is provided on the workpiece. For the fixed-point part to be detected, the detection hole on the fixed-point detection rod 31 is pushed. If the fixed-point detection rod 31 can be inserted into the detection hole, it means that the position and size of the detection hole meet the requirements, otherwise it does not meet the requirements.

[0048] In this embodiment, the flip arm clamping assembly 4 has the functions of clamping positioning and top size detection of the workpiece, the side wall positioning assembly 6 has the functions of side positioning of the workpiece and side wall flanging and edge detection of the workpiece, the double-track positioning assembly 5 has the functions of bottom positioning of the workpiece and bottom detection of the workpiece, and the fixed-point detection rod 31 realizes the function of fixed-point detection, thereby realizing all-round detection of the workpiece.
