DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 As shown, a jig for detecting position and size includes a mounting plate 1, a base 2 is mounted below the mounting plate 1; a detection pin 3, the detection pin 3 is mounted on one side of the mounting plate 1; a connecting rod 4, the connecting rod 4 is connected to the inner side of the base 2; a placement seat 5, the placement seat 5 is mounted on one end of the connecting rod 4, and the placement seat 5 and the detection pin 3 are arranged on the same side of the mounting plate 1, and the placement seat 5 is used to place a sheet metal part 6; a baffle 7, the baffle 7 is mounted on the other end of the connecting rod 4; a spring 8, the spring 8 is sleeved on the connecting rod 4, and one end of the spring 8 is pressed against the base 2, and the other end of the spring 8 is pressed against the baffle 7; a scale 9, the scale 9 is arranged above the connecting rod 4, and the central axis of the connecting rod 4 is arranged parallel to the horizontal center line of the scale 9;

[0023] When inspecting the sheet metal part 6, first place the sheet metal part 6 on the placement seat 5, and adjust the sheet metal part 6 so that the hole on the sheet metal part 6 is aligned with the detection pin 3 on the mounting plate 1 supported by the base 2. Due to the elastic force of the spring 8, the connecting rod 4 will extend toward the side of the handle 101, and at the same time drive the placement seat 5 to approach the side of the detection pin 3, thereby driving the sheet metal part 6 to approach the detection pin 3, and then the detection pin 3 is aligned with the sheet metal part 6 and inserted, and then observe whether the pointer 701 indicates on the indication area 901 of the ruler 9 to judge the qualification of the hole on the sheet metal part 6. The small column section 301 and the large column section 302 of the detection pin 3 can quickly detect whether the inspected part is qualified. It is suitable for mass-produced products, improves detection efficiency, and reduces detection costs. In addition, by determining whether the two detection pins 3 can be inserted into two corresponding holes at the same time, it is possible to quickly detect whether the spacing between the two holes is qualified.

[0024] A handle 101 for holding is installed on the other side of the mounting plate 1. The handle 101 on the mounting plate 1 facilitates holding and controlling the device.

[0025] The detection pin 3 includes a small column section 301 and a large column section 302. The small column section 301 is arranged on the side close to the placement seat 5, and the large column section 302 is arranged on the side close to the mounting plate 1. A guide head 303 is arranged on the side close to the placement seat 5 of the small column section 301. The detection pin 3 is used to detect the hole size on the sheet metal part 6. The spacing between the detection pins 3 corresponds to the hole spacing setting of the sheet metal part 6.

[0026] When the placement seat 5 gradually approaches the detection pin 3, the hole of the sheet metal 6 on the placement seat 5 is aligned with the detection pin 3, which is guided by the guide head 303 of the detection pin 3, and then the small column segment 301 of the detection pin 3 is inserted into the hole of the sheet metal 6. When the hole of the sheet metal 6 cannot insert the small column segment 301 of the detection pin 3 or can insert both the small column segment 301 of the detection pin 3 and the large column segment 302 of the detection pin 3, the size of the hole of the sheet metal 6 is unqualified. When the hole of the sheet metal 6 can be inserted into the small column segment 301 but not the large column segment 302, it means that the hole of the sheet metal 6 is qualified. When the distance between the two holes on the sheet metal 6 is measured, since the distance between the two detection pins 3 on the mounting plate 1 is set according to the standard distance between the two holes, when one hole can be aligned with the detection pin 3 and inserted, and the other hole cannot be aligned with the detection pin 3, it means that the distance between the two holes is unqualified.

[0027] A slot 501 for clamping and placing the sheet metal part 6 is provided on the inner side of the bottom end of the placement seat 5 . The slot 501 is used to clamp the sheet metal part 6 to prevent the sheet metal part 6 from falling off the placement seat 5 .

[0028] A pointer 701 is provided at the upper end of the baffle 7, and the pointer 701 indicates on the scale 9, and a grip 702 is installed on the outer side of the baffle 7; an indication area 901 is provided on the upper surface of the scale 9, and when the small column section 301 of the detection pin 3 enters into the sheet metal part 6, the pointer 701 indicates on the indication area 901;

[0029] When the pointer 701 indicates on the indication area 901, it means that the hole of the sheet metal 6 is just in the small column section 301 of the detection pin 3, which means that the hole of the sheet metal 6 is qualified. When the pointer 701 does not reach the indication area 901, it means that the hole of the sheet metal 6 is unqualified. In this way, it is possible to quickly determine whether the hole of the sheet metal 6 is qualified, and by providing the handle 702, the elastic force of the spring 8 can be overcome by holding it so that the connecting rod 4 extends to the other end, making it convenient for the sheet metal 6 to be placed on the placement seat 5.

[0030] Working principle: when inspecting the sheet metal 6, first place the sheet metal 6 on the placement seat 5, and adjust the sheet metal 6 so that the hole on the sheet metal 6 is aligned with the detection pin 3 on the mounting plate 1. Due to the elastic force of the spring 8, the placement seat 5 will be driven to approach the side of the detection pin 3, thereby driving the sheet metal 6 close to the detection pin 3, and then the detection pin 3 is aligned with the sheet metal 6 and inserted, and then observe whether the pointer 701 indicates on the indication area 901 of the ruler 9 to judge the acceptability of the hole on the sheet metal 6.
