Detailed Embodiments

[0021] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0022] Figure 1A pantograph horn is shown, which has opposite mounting ends 15 and an arcuate end 16. Among them, the mounting end 15 includes a connecting portion 17 and a rib portion 18 provided at the bottom of the connecting portion 17. A vertical mounting hole 19 for connecting to the bow head is provided on the connecting portion 17, a transverse mounting hole 20 is provided on the rib portion 18, and a V-shaped groove 21 is also formed on the connecting portion 17; an arc surface 22 is formed on the arcuate end 16.

[0023] During the manufacturing process, the above-mentioned pantograph horn needs to be detected. For the local dimension detection of the mounting end 15 and the arcuate end 16, it can be carried out by manual measurement. However, due to the unique shape of the pantograph horn, it is difficult to conveniently complete the detection of its overall dimensions with a caliper.

[0024] In view of the above technical problems, as Figure 2 , Figure 3 shown, the present utility model provides a pantograph horn detection tooling, which includes a base 1. A support column 2 is provided on one side of the base 1, and a positioning groove 4 is formed on the other side. An installation groove 3 that fits the shape of the horn mounting end 15 is provided on the support column 2, and the positioning groove 4 is adapted to have a shape that fits the arcuate end 16 of the horn. During detection, only by respectively clamping the mounting end 15 and the arcuate end 16 of the pantograph horn into the installation groove 3 and the positioning groove 4, it can be conveniently judged whether its external dimensions are qualified.

[0025] Preferably, weight-reducing grooves 14 can be provided on the base 1 and the support column 2 to reduce the weight of the tooling and reduce manufacturing consumables.

[0026] In some embodiments, the positioning groove 4 is specifically configured as an arc-shaped groove that fits the arc surface 22 of the above-mentioned arcuate end 16, and a pressing member for pressing the arc surface 22 against the positioning groove 4 is also provided on the base 1.

[0027] For example, the abutting member 5 preferably includes an abutting block 9 that can be pushed out to the side of the positioning groove 4. More specifically, a kidney-shaped hole 10 is provided on the abutting block 9. Fasteners such as bolts can pass through the kidney-shaped hole 10 and be screwed to the base 1. When the fastener is in a relaxed state, the tester can push the abutting block 9 to be pushed out to the side of the positioning groove 4, so as to drive the arc surface 22 of the horn arcuate end 16 to be pressed against the positioning groove 4. At this time, the fastener can be tightened again to maintain the pushed-out state of the abutting block 9.

[0028] In order to further detect the dimensions of the horn mounting end 15, the present utility model also adapts a first detection rod 6 to be slidably arranged vertically on the support column 2, and a detection block 11 to be slidably arranged longitudinally on the support column 2. After the mounting end 15 of the pantograph horn is inserted into the installation groove 3, the first detection rod 6 can be inserted into the above-mentioned vertical mounting hole 19 to detect whether its hole position is qualified, and the detection block 11 can slide into the above-mentioned V-shaped groove 21 to detect whether its groove dimension is qualified.

[0029] For example, a through hole 12 for the first detection rod 6 to pass through may be provided on the detection block 11. Thus, the detection block 11 can be inserted into the V-shaped groove 21 first, and then the first detection rod 6 can be passed through the through hole 12 to detect the vertical installation hole 19. With the setting of the through hole 12, the detection block 11 and the first detection rod 6 are not likely to interfere with each other, and only by performing the above detection steps can the detection of the V-shaped groove 21 and the vertical installation hole 19 be conveniently completed.

[0030] In some embodiments, a rotating block 7 is rotatably provided on the side wall of the support column 2 below the horn. For example, the rotating block 7 is preferably U-shaped in cross section, and a second detection rod 8 is also passed through its two connecting arms 23. After the mounting end 15 of the pantograph horn is inserted into the mounting groove 3, the rotating block 7 can be driven to rotate until the two connecting arms 23 are clamped on the convex rib portion 18, and then the second detection rod 8 is slid to be inserted into the horizontal installation hole 20 to detect the qualification of its hole position. It can be understood that the rotatable setting of the rotating block 7 is not likely to interfere with the insertion of the pantograph horn into the mounting groove 3.

[0031] For example, a probe 13 is elastically movable along the longitudinal direction on the support column 2. More specifically, a mounting seat is provided on the side wall of the support column 2, and the probe 13 is connected to the mounting seat through an elastic member such as a spring, and a connection hole communicating with the mounting groove 3 is also provided on the support column 2. When the elastic member is in a natural state, the probe 13 is held in the connection hole; and after the mounting end 15 of the pantograph horn is inserted into the mounting groove 3, it can be judged whether the end face of the horn mounting end 15 is of a qualified size by pressing whether the probe 13 bounces.

[0032] The detection process of the present utility model is as follows:

[0033] The mounting end 15 and the arc end 16 of the pantograph horn are respectively snapped into the mounting groove 3 and the positioning groove 4. If the mounting end 15 interferes with the mounting groove 3 and its end face cannot be snapped into the mounting groove 3, it can be judged that the external dimension of the pantograph horn is out of tolerance.

[0034] After the mounting end 15 of the pantograph horn is inserted into the mounting groove 3, the vertical mounting hole 19, the horizontal mounting hole 20 and the V-shaped groove 21 can be respectively detected by sliding the first detection rod 6, the second detection rod 8 and the detection block 11. If the above components cannot slide smoothly, it can be judged that the corresponding part is out of tolerance;

[0035] When the probe 13 bounces after being pressed, the probe 13 will abut against the end face of the mounting end 15. At this time, it can be judged that the length dimension of the horn is smaller than the designed dimension.

[0036] The above are only the preferred embodiments of the present utility model. It should be understood that the present utility model is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields. And any changes and modifications made by those skilled in the art without departing from the spirit and scope of the present utility model shall fall within the protection scope of the appended claims of the present utility model.
