As a preferred embodiment, the quick-change pin head is provided as a hexagon socket head.
As a preferred embodiment, the quick-change pin head is provided as a pan head screw head.
As a preferred embodiment, the quick-change pin head is provided as a countersunk head.
In a preferred embodiment, a taper pin is arranged in the middle of the quick-change pin.
In a preferred embodiment, a spring washer is added at the lower end of the quick-change pin body.
Compared with the prior art, the utility model relates to a quick change round pin mechanism for auto clamp field's beneficial effect is:
at first, must use the hank spiral shell twister when current cylindric lock uses, and the utility model discloses then rely on the screw rod that self carried, the screw rod diameter slightly is less than cylindric lock round pin body diameter, realizes quick installation with the nut packing ring.
Secondly, must use the pin puller when current cylindric lock is dismantled, and the utility model discloses then rely on from taking the spiral shell head to realize dismantling fast. The middle section is a cylindrical pin body, so that the positioning is accurate, and the elongated screw head and the tail end screw are matched with the further auxiliary reinforcement of the nut and the washer, so that the positioning is more accurate and stable.
Especially in the auto clamp field, because current mechanism needs two locating pins and four bolts just can realize connecting, it is very inconvenient to dismantle, the utility model discloses then possess the characteristics of changing the outfit fast, can obviously improve at the position of multi-vehicle type conversion and tear open the speed of changing, effectively improve production efficiency.

In the figure: 1. the fixture comprises an elongated hexagonal screw head, 2 cylindrical pin bodies, 3 screws, 4 matched nuts, 5 matched flat washers, 6 locating pin holes I, 7 locating pin holes II, 8 BASE plates, 9 locating pin holes III and 10 fixture angle supports.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
In a first embodiment, as shown in fig. 1 to 4, a quick-change pin mechanism for a fixture corner support comprises a quick-change pin mechanism, a fixture corner support 10, a BASE plate 8;
the quick-change pin mechanism comprises a quick-change pin, a matched nut 4 and a matched flat washer 5, the head of the quick-change pin is an elongated hexagonal screw head 1, the middle of the quick-change pin is a cylindrical pin body 2, the tail of the quick-change pin is a screw rod 3, the quick-change pin head, the cylindrical pin body 2 and the tail of the quick-change pin are of an integrated structure, and the diameter of the screw rod 3 is slightly smaller than that;
the bottom surface of the clamp angle support 10 is provided with four positioning pin holes I6, and the side surface is provided with six positioning pin holes II 7; and a third positioning pin hole 9 is arranged on the BASE plate.
When the quick-change pin is used, the positioning pin hole III 9 on the BASE plate is selected, the positioning pin hole I6 on the bottom surface of the clamp angle support corresponds to the positioning pin hole III 9, the quick-change pin of the utility model is inserted into the two positioning pin holes I6 on the oblique angle of the clamp angle support 10, the matched nut 4 and the matched flat washer 5 are installed, and the two remaining positioning pin holes I6 are pressed with common bolts; the middle section is a cylindrical pin body 2, so that the positioning is accurate, the elongated screw head and the tail end screw 3 are matched with a matched nut 4 and a matched flat washer 5 for further auxiliary reinforcement, and two additional bolts are added, so that the clamp angle support 10 is accurately and stably positioned; if special accuracy requirements require, a twist thread device can be used for the positioning pin hole, so that the positioning accuracy is further improved;
