Description

Technical Field

[0001] The present application relates to the technical field of testing equipment, and in particular to a rocker arm assembly test fixture. Background Art

[0002] The engine structure is one of the many related structures that make up a vehicle, among which the rocker arm structure plays a very important role in the structure of the engine. The rocker arm structure includes a rocker arm shaft, and a rocker arm is installed on the rocker arm shaft. The rotation of the rocker arm shaft drives the rocker arm to rotate, and finally realizes the corresponding function.

[0003] In the related art, after the rocker arm structure is generated, it is usually necessary to inspect the rocker arm structure to ensure that the size of the rocker arm structure is correct so that it can be installed in the corresponding structure. When inspecting, the operator usually uses a vernier caliper to detect the distance between the rocker arm as a whole and the related structure, and then determine whether the size meets the relevant data.

[0004] With regard to the above-mentioned related technologies, measuring the distances one by one by using a vernier caliper is time-consuming and labor-intensive, and increases the workload of operators, reduces work efficiency, is not convenient for mass production of related structures, and thus affects product production. Utility Model Content

[0005] In order to be able to inspect the rocker arm structure more quickly, improve the speed and accuracy of inspection, and reduce the workload of operators, the present application provides a rocker arm assembly inspection fixture.

[0006] This application provides a rocker arm assembly inspection fixture, which adopts the following technical solutions:

[0007] The rocker arm assembly inspection fixture comprises a support plate and a limit plate, wherein the support plate is fixed on the table;

[0008] The limiting plate is fixedly connected to the supporting plate, the limiting plate is provided with a fixing groove, the limiting plate is provided with a plurality of accommodating grooves at the fixing groove, and the accommodating grooves are communicated with the fixing grooves.

[0009] By adopting the above technical solution, the support plate provides support for the installation of the limit plate, the fixing groove provides a limit space for the rocker shaft, and the receiving groove provides a limit space for the rocker arm. When the rocker arm mechanism needs to be inspected, the operator first places the rocker arm shaft in the fixing groove. At this time, the rocker arm shaft that meets the relevant specifications will fall back into the receiving groove, and the rocker arm structure that does not meet the specifications cannot enter the fixing groove and the receiving groove. At this time, the operator only needs to take out the non-compliant rocker arm structure to realize the relevant selection of the rocker arm structure, thereby improving the convenience of operation.

[0010] Optionally, the limiting plate is provided with two guide grooves, the two guide grooves are respectively located on both sides of the opening direction of the fixing groove, and the guide groove is connected to the fixing groove.

[0011] By adopting the above technical solution, the limiting plate is provided with two guide grooves, which are connected with the fixing groove, so that the fixing groove has a larger groove width on the side close to the opening end, which is convenient for the operator to insert the rocker arm shaft. At the same time, the guide groove gradually narrows, thereby gradually improving the limiting effect on the rocker arm shaft.

[0012] Optionally, each of the guide grooves is provided with a sliding groove at an opening, and the sliding groove is connected to an inner cavity of the fixing groove.

[0013] By adopting the above technical solution, the setting of the sliding groove makes it easy for the rocker arm to enter the accommodating groove. At the same time, the groove width of the accommodating groove gradually decreases, further improving the limiting effect of the rocker arm, making it easier for the operator to judge whether the position of the rocker arm is correct.

[0014] Optionally, each side edge of the support plate and the limiting plate is rounded.

[0015] By adopting the above technical solution, the side edges of the support plate and the limit plate are chamfered, which can reduce the sharpness of the edges of the support plate and the limit plate, thereby providing a certain safety guarantee for the operator and reducing the possibility of the operator being scratched.

[0016] Optionally, a fixing plate is provided at each corner of the support plate away from the limiting plate, and the fixing plate is fixedly connected to the support plate. A friction pad is provided on the end surface of the fixing plate away from the support plate, and the friction pad is fixedly connected to the fixing plate.

[0017] By adopting the above technical solution, the fixing plate can create a certain distance between the supporting plate and the desktop. At the same time, the fixing plate can provide support for the installation of the friction pad. The friction pad can increase the friction between the fixing plate and the desktop, thereby preventing the fixing plate from sliding along the desktop, thereby providing stable support for the supporting plate.

[0018] Optionally, a mounting rod is provided at the support plate, the mounting rod is fixedly connected to the support plate, a plurality of sliding blocks are provided on the side wall of the mounting rod along the length direction, the sliding blocks are slidably connected to the mounting rod, the sliding blocks at both ends are fixedly connected to fixed blocks, and the remaining sliding blocks are provided with two abutment rods, the abutment rods are slidably connected to the sliding blocks.

[0019] By adopting the above technical solution, the mounting rod is fixed to the top wall of the support plate, and at the same time provides support for the installation and sliding of the sliding block. The operator controls the sliding block to move along the mounting rod, thereby driving the fixed blocks at both ends to slide along the mounting rod, thereby limiting the rocker arm shafts of different lengths, and at the same time, sliding the abutment rod to limit the rocker arms of different widths, thereby improving the applicability of the device and improving the operator's conception.

[0020] Optionally, the sliding block is provided with a sliding groove, and an adjustment component is provided in the sliding groove, and the adjustment component includes a gear and two racks, the gear is rotatably connected to the sliding block, the two racks are respectively located on both sides of the gear axis direction, the rack is meshed with the gear and the rack is slidably connected to the sliding block, and the abutment rod is fixedly connected to the rack.

[0021] By adopting the above technical solution, the slide groove provides support for the installation of the adjustment component. At the same time, the operator rotates the gear, the gear and the rack engage, and the two racks slide in the direction of approaching or moving away from each other, thereby driving the abutment rods to slide in the direction of approaching or moving away from each other, so that the two abutment rods can limit rocker arms of different sizes, thereby improving the applicability of the device.

[0022] Optionally, each of the racks is equipped with a fixed frame, the rack is passed through an inner cavity of the fixed frame, and the fixed frame and the sliding block are fixedly connected.

[0023] By adopting the above technical solution and setting the fixed frame, the sliding direction of the rack can be further limited, and thus the sliding direction of the abutment rod can be limited, while providing certain support for the abutment rod.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. By setting the support plate and the limit plate, the setting of the fixing groove and the receiving groove, the rocker shaft and the rocker arm can be limited, and the rocker shaft and the rocker arm that do not meet the specifications cannot enter the fixing groove and the receiving groove, thereby improving the limit of the workpiece;
