[0027] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] In the embodiment of the present utility model, Figure 1-Figure 3 As shown, the igniter test fixture includes: a support platform, a first positioning member, a second positioning member and a cylinder 6; the support platform includes a first support portion 1 and a second support portion 2 extending in opposite directions, and the first support portion 1 and the second support portion 2 are integrally formed through a connecting portion 3; the first positioning member is arranged on the first support portion 1, and a clamping cavity opening upward is constructed between the first positioning member and the first support portion 1 and the connecting portion 3; the second positioning member includes a connected support frame 4 and a plurality of positioning suction cups 5, the support frame 4 slides through the connecting portion 3, and links the positioning suction cups 5 to slide in the clamping cavity to approach or move away from the first positioning member; the cylinder 6 is arranged on the second support portion 2, and is used to drive the support frame 4 to move.

[0029] Specifically, in the embodiment of the utility model, the support platform includes a first support portion 1 and a second support portion 2 extending in opposite directions, the first support portion 1 and the second support portion 2 are connected by a vertically arranged connecting portion 3, and the three are integrally formed to construct the main structure of this clamp; Figure 2As shown, the first supporting portion 1 and the connecting portion 3 as well as the second supporting portion 2 and the connecting portion 3 are arranged perpendicular to each other, thereby improving the structural stability of the main structure.

[0030] In an embodiment of the utility model, a first positioning member is provided on the first supporting portion 1, and the first positioning member is located at one end of the first supporting portion 1 away from the connecting portion 3, so that a clamping cavity with an opening facing upward can be constructed between the first supporting portion 1 and the connecting portion 3 for accommodating the igniter; in addition, after the igniter is placed in the clamping cavity, one side surface of its outer shell abuts against the first positioning member, which is used to position the side surface of the outer shell and confine the igniter in the accommodating cavity.

[0031] In an embodiment of the utility model, a support frame 4 is passed through the connecting portion 3, and the support frame 4 can slide back and forth relative to the connecting portion 3, and a plurality of positioning suction cups 5 are arranged thereon, and the positioning suction cups 5 are suspended in the clamping cavity and can move together with the support frame 4, so as to be able to approach or move away from the first positioning member, that is, the first positioning member and the positioning suction cups 5 are arranged relative to each other, and can be used to clamp or release the opposite sides of the igniter housing.

[0032] Specifically, since a gap is formed between the inner wall of the clamping cavity and the igniter housing, the size of the gap will directly affect the test performance of the igniter. Therefore, a positioning suction cup 5 is arranged in the clamping cavity, and a cylinder 6 for driving the support frame 4 to move back and forth is arranged on the second support part 2. Under the push of the support frame 4, the positioning suction cup 5 can be gradually adsorbed on the igniter housing, and with the cooperation of the first positioning piece, the igniter housing can be clamped between the first positioning piece and the positioning suction cup 5, so as to realize precise positioning of the igniter, unify the position of the igniter in the clamping cavity, and thus improve the test accuracy of the igniter. Furthermore, by using the cylinder 6 to drive the support frame 4 and the positioning suction cup 5, the moving stroke of the positioning suction cup 5 can be unified, the manual judgment of the spacing link can be reduced, and the degree of automation and the test efficiency are high; furthermore, the positioning suction cup 5 is set on the support frame 4 to replace the original push rod directly contacting the igniter housing. The positioning suction cup 5 can be gradually adsorbed on the igniter housing under the push of the support frame 4. On the one hand, it can push the igniter to move in the direction of the first positioning member to achieve the purpose of rapid clamping; on the other hand, it can increase the contact area with the igniter housing, so that the surface of the igniter housing is balanced and pushed into place at one time; and the support frame 4 can indirectly contact the igniter housing, which can protect the housing from being scratched or damaged by the support frame 4. On the contrary, when the support frame 4 links the positioning suction cup 5 to move in the direction of the second support part 2, the positioning suction cup 5 can pull the igniter back and separate from the first positioning member for easy access. Of course, in order to make the positioning suction cup 5 detach from the igniter housing after moving to a certain distance, a step can be set at one end of the first support part 1 close to the connecting part 3 to prevent the igniter from continuing to move backward. At the same time, the support frame 4 is continuously pulled under the drive of the cylinder 6 to gradually detach the positioning suction cup 5 from the igniter.

[0033] The utility model clamps the igniter between the first positioning member and the sliding positioning suction cup 5, and controls the moving stroke of the positioning suction cup 5 by the cylinder 6 to unify the clamping position of the igniter, so that it can maintain the same posture for testing, so that the igniter and the metal sheet are at a reasonable distance, and no manual positioning is required in the process. The degree of automation is suitable for batch testing. Furthermore, the newly added positioning suction cup 5 can absorb or release the igniter shell, which can not only increase the contact area with the surface of the igniter shell, so that the igniter is evenly stressed and can be pushed into place at one time, but also protect the igniter shell from being scratched. At the same time, the igniter can also be pulled after the test is completed, which is convenient for taking and placing the igniter and protecting the first positioning member from being touched, so that the first positioning member can always be used as a positioning basis.

[0034] like Figure 2 As shown, in one embodiment, the first positioning member includes a plurality of positioning rods 7 arranged in the vertical direction. Specifically, in order to position the igniter at multiple points, the first positioning member is defined as two positioning rods 7 arranged at intervals in the front-to-back direction in this embodiment, each positioning rod 7 is arranged vertically in the vertical direction, and its lower part is fixed to the first support part 1, so as to prevent the igniter from escaping from the clamping cavity. Of course, in other embodiments, the number of positioning rods 7 can also be other, which is not limited here.

[0035] like Figure 3 As shown, in one embodiment, the support frame 4 has a plurality of installation points 401 arranged at intervals, and the plurality of installation points 401 are arranged one-to-one with the plurality of positioning suckers 5, and are used to fix each of the positioning suckers 5. Specifically, in order to install the positioning sucker 5 on the support frame 4 and keep the two relatively still, the present embodiment sets the installation points 401 on the support frame 4, and uses the installation points 401 to fix the positioning sucker 5. The support frame 4 is a T-shaped structure, and the installation points 401 are formed at its horizontal ends, and the vertical ends of the support frame 4 are used to connect to the cylinder 6.

[0036] Preferably, the above-mentioned installation point 401 is a threaded through hole formed on the support frame 4, and a mounting seat 8 is provided on the positioning suction cup 5, so that the mounting seat 8 can be screwed on the threaded through hole, which not only makes the support frame 4 and the positioning suction cup 5 detachable and connected, and facilitates the installation or regular replacement of the positioning suction cup 5, but also the position of the positioning suction cup 5 can be fine-tuned during installation so that it can be adsorbed on or detached from the igniter housing.

[0037] like Figure 3As shown, in one embodiment, the support frame 4 is provided with a first stopper 9 and a second stopper 10 at intervals, the first stopper 9 and the second stopper 10 are separated by the connecting portion 3, and the first stopper 9 is located in the clamping cavity, and the support frame 4 links the first stopper 9 and the second stopper 10 to alternately abut against the connecting portion 3. Specifically, in order to limit the moving distance of the support frame 4, this embodiment is provided with a first stopper 9 and a second stopper 10 fixedly sleeved on the support frame 4, and the first stopper 9 and the second stopper 10 are separated by the connecting portion 3, so that the first stopper 9 is located in the clamping cavity, and the second stopper protrudes outside the clamping cavity; in this way, under the traction of the cylinder 6, the support frame 4 can drive the first stopper 9 and the second stopper 10 to move together, so that the first stopper 9 or the second stopper 10 abuts against the connecting portion 3, and the movement of the positioning suction cup 5 can be limited by the limiting of the two. Of course, the first stopper 9 and / or the second stopper 10 can be made of elastic material to play a buffering role.

[0038] like Figure 2 As shown, in one embodiment, the first support portion 1 is provided with a first opening 101 that runs through from top to bottom. In order to avoid the raised portion of the igniter housing, this embodiment provides a first opening 101 that runs through from top to bottom on the first support portion 1. The first opening 101 can accommodate the raised portion, so that the other flat portions of the housing can slide and fit with the first support portion 1. In addition, the provision of the first opening 101 can also reduce the contact area between the first support portion 1 and the igniter housing, so that the igniter can slide into the clamping cavity. Of course, the first support portion 1 is provided with a second opening 102 that opens upward and forms a limiting step surface. On the one hand, it can avoid the wire portion of the igniter, and on the other hand, the shape of the igniter housing can be used to slide and abut against the limiting step surface, so as to further constrain the clamping position of the igniter.

[0039] like Figure 1 As shown, in one embodiment, the connecting portion 3 is provided with a first movable platform 11, and a second movable platform 12 is suspended below the first movable platform 11, and the first movable platform 11 and the second movable platform 12 can slide relative to each other. Specifically, during assembly, in order to accurately clamp the position of the cavity, this embodiment sets a first movable platform 11 and a second movable platform 12 that slide relative to each other, so that the first movable platform 11 moves in conjunction with the supporting platform, and the first movable platform 11 and the supporting platform are locked by screws after being moved into place. Of course, matching slide rails and slide grooves can be set between the two movable platforms, which will not be described in detail here.

[0040] like Figure 4As shown, the present embodiment further provides a test device, including a test platform and two test fixtures arranged in a mirror image, the test platform having a test station and two clamping stations located on both sides of the test station, the two clamping stations are arranged in a one-to-one correspondence with the two test fixtures, and the second movable platform 12 is installed at the test platform; the specific structure of the igniter test fixture refers to the above embodiment, and since the present test device adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
