[0002] The rocker arm is an automotive component, which consists of two parts: an iron part and an overmolded part. The dimensions measured by the jig are the key dimensions controlled by the customer, and the bottom surface of the injection molding needs to be used as the reference.
[0003] like Figure 4 As shown, when the existing imager is used for measurement, the part 1 is first placed on the tooling base 8, the bottom hole of the part 1 needs to be aligned with the positioning pin 10 and inserted, and then the quick pressing head 9 is pressed.
[0004] like Figure 5 As shown, place the tooling 2 with the part 1 on the imager work surface 3, start the computer 5, move the work platform 3 with the adjustment wheel, move the part 1 under the imager lens 6, measure it through the imager software, and the measured data is displayed on the display screen 7.
[0005] The quick pressing head of the above-mentioned existing fixture can only press down a point. Since the bottom surface of the injection molding is uneven, pressing down a point will cause one side of the part to warp up. In addition, the hole at the bottom of the part has a size tolerance, and there will always be a slight shake when inserting the locating pin, resulting in large differences in the measurement results.
[0006] Therefore, we propose a jig that is convenient for flattening and positioning the pendulum rod, so as to solve the above-mentioned problems. Utility Model Content

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a jig for flattening and positioning a swing rod, comprising: a jig base, on which two guide rails and a connecting bracket are vertically mounted;
[0009] One side of the connecting bracket is connected to the tooling base, and the other side is connected to the bottom pressing block through a fixing pin. The root of the bottom pressing block is equipped with a bottom compression spring, and the mouth of the bottom pressing block presses the parts tightly.
[0010] A sliding plate is slidably arranged on the two guide rails, and an eccentric shaft is arranged on the top of the two guide rails;
[0011] The pressing block seat is fixedly mounted on the sliding plate;
[0012] Four adjustable pressing blocks are arranged on the pressing block seat, and the upper part of the sliding plate is connected with the eccentric shaft through a pressing spring.
[0013] Preferably, each of the two guide rails is provided with a sliding block, and the sliding block is provided with a sliding plate.
[0014] Preferably, the pressing block seat and the sliding plate are connected by arranging a circular pin.
[0015] Preferably, an eccentric shaft handle is installed on the eccentric shaft.
[0016] Compared with the prior art, the beneficial effects of the utility model are:
[0017] The new fixture can press the parts at four points at the same time, so that the bottom surface of the injection molding can be more evenly attached to the plane of the fixture, avoiding warping on one side, and adding a horizontal clamping device to avoid horizontal shaking. This fixture can effectively solve the problem of large measurement errors caused by improper placement of parts. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0025] 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.
[0026] See also Figure 1-4 The utility model provides a technical solution: a jig for flattening and positioning a swing rod, comprising: a jig base 8, on which two guide rails 9 and a connecting bracket 21 are vertically mounted;
[0027] One side of the connecting bracket 21 is connected to the tooling base 8, and the other side is connected to the bottom pressing block 12 through the fixing pin 20. The root of the bottom pressing block 12 is equipped with a bottom compression spring 13. Pressing the root of the bottom pressing block 12 can make the bottom pressing block 12 rotate clockwise around the fixing pin 20, and the placement position of the part 1 will become larger. Place the part 1 on the tooling base 8, loosen the root of the bottom pressing block 12, and the rebound force of the bottom compression spring 13 makes the bottom pressing block 12 rotate counterclockwise around the fixing pin 20. The mouth of the bottom pressing block 12 presses the part 1 to prevent the horizontal movement of the part 1.
[0028] A slider 10 is mounted on each of the two guide rails 9, and a sliding plate 11 is mounted on the slider 10;
[0029] A pressing block seat 17 is fixedly mounted on the sliding plate 11. Specifically, the pressing block seat 17 and the sliding plate 11 are connected via a circular pin 18.
[0030] An eccentric shaft 14 is mounted on the top of the two guide rails 9;
[0031] Four adjustable pressing blocks 19 are installed on the pressing block seat 17. The top of the sliding plate 11 is connected to the eccentric shaft 14 through a compression spring 15. An eccentric shaft handle 16 is installed on the eccentric shaft 14. When the eccentric shaft handle 16 is turned, the force of the compression spring 15 can make the sliding plate 11 move downward. When the part 1 is placed on it, the four pressing blocks 19 on the pressing block seat 17 can press the part 1 at the same time.
[0032] When in use, press the root of the bottom pressing block 12, place the part 1 on the tooling base 8, loosen the root of the bottom pressing block 12, and the bottom pressing block 12 rotates counterclockwise around the fixing pin 20 through the bottom compression spring 13 to press the part 1 to prevent the horizontal movement of the part 1, rotate the eccentric shaft handle 16, and the force of the compression spring 15 drives the sliding plate 11, and the four pressing blocks 19 on the sliding plate 11 move downward to longitudinally press the four points of the part 1, so that the part 1 is evenly attached to the tooling plane;
[0033] The new fixture can press part 1 at four points at the same time, so that the bottom surface of the injection molding can be more evenly attached to the fixture plane, avoiding warping on one side, and adding a horizontal clamping device to avoid horizontal shaking. This fixture can effectively solve the problem of large measurement errors caused by improper placement of parts.
