Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to a housing parallelism inspection tool. Background Technology

[0002] The steering gear is an automotive component. During the manufacturing process, it is necessary to inspect the parallelism of the two mounting feet of the steering gear housing to ensure that the parallelism meets the requirements. Currently, no specific solution for inspecting the parallelism of the steering gear housing mounting feet has been found in the existing technology. Therefore, it is necessary to provide a tool for inspecting the parallelism between the two end faces of the housing. Summary of the Invention

[0003] The purpose of this invention is to provide a shell parallelism gauge, which is used to detect the parallelism between two end faces of a shell.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a housing parallelism gauge, including a base, a positioning bracket disposed on the base, and a clamping assembly for pressing the steering gear housing against the positioning bracket. The base is provided with a first guide rail, the first guide rail is connected to a first slide, the first slide is provided with a bracket, and the bracket is equipped with a lever dial indicator.

[0005] By adopting the above technical solution, the steering gear housing is placed on the positioning bracket, and the clamping assembly clamps and fixes it, so that the two mounting feet of the steering gear housing face the lever dial indicator. The first slide is moved along the first guide rail, so that the lever dial indicator contacts the two mounting feet in sequence. Two values ​​can be read from the lever dial indicator in sequence. By calculating the difference between the two values, it can be determined whether the parallelism between the two mounting feet is within the error range.

[0006] A further configuration of the present invention is as follows: the number of positioning brackets is two, the positioning brackets are provided with end positioning grooves, the end positioning grooves are for the end of the steering gear housing to be embedded; the number of pressing components is two and each corresponds to one of the two positioning brackets, the pressing component includes a support fixed to the positioning bracket, a connecting rod hinged to the support, a handle hinged to the support and used to press down the connecting rod, a pressing column provided on the connecting rod, and a pressing head located at the lower end of the pressing column.

[0007] By adopting the above technical solution, the swing handle can press down or lift the connecting rod, thereby achieving the function of pressing the steering gear housing or releasing the steering gear housing.

[0008] A further feature of the present invention is that it also includes an auxiliary positioning seat, the auxiliary positioning seat having an auxiliary positioning groove for the steering gear housing side to be embedded in.

[0009] By adopting the above technical solution, the auxiliary positioning groove is used to position and support the side of the steering gear housing, preventing the steering gear housing from rotating and improving the accuracy of parallelism detection.

[0010] A further feature of the present invention is that the first guide rail is also connected to a second slide block, and the second slide block is provided with a flexible support portion.

[0011] By adopting the above technical solution, since the steering gear housing itself has a certain weight, if workers were to carry it directly off the positioning bracket, it would significantly increase the labor intensity of the workers in the process of large-scale, continuous operation.

[0012] After the inspection is completed, the second slide can be moved so that the flexible support is located on the side of the steering gear housing. The steering gear housing can be transferred onto the flexible support before being removed. The flexible support can be made of soft materials such as rubber, serving as a buffer and support.

[0013] A further configuration of the present invention is as follows: the first guide rail and the auxiliary positioning seat are respectively located on both sides of the positioning support, the positioning support is provided with a top seat that can be raised and lowered, the base is rotatably provided with a rotating shaft, the rotating shaft is fixed with a first gear and a second gear, the top seat is provided with a vertically placed first rack, the first rack meshing with the first gear; the second slide is fixed with a horizontally placed second rack, the second rack being used to drive the rotating shaft to rotate after meshing with the second gear.

[0014] By adopting the above technical solution, after the parallelism test is completed, after the second slide is moved, the second gear of the second slide begins to contact and mesh with the second gear. The second gear drives the rotating shaft and the first gear to rotate. The first gear drives the top seat to rise. After the top seat rises, it contacts and pushes the steering gear housing to flip and leave the end positioning groove, so that it falls onto the flexible support part.

[0015] A further configuration of the present invention is as follows: the base is slidably connected to a pull rod, the pull rod is hinged to a movable rod, the movable rod is hinged to the second slide block, the pull rod is connected to two steel wire ropes, the steel wire ropes are respectively connected to two handles, and the base is provided with a plurality of guide rings, the guide rings being for the steel wire ropes to pass through.

[0016] By adopting the above technical solution, during the movement of the second slide, the movable rod drives the pull rod to move, and the pull rod drives the two handles to swing through the wire rope, which releases the pressure head that is pressed against the steering gear housing, so that the top seat can lift the steering gear housing and let it fall onto the flexible support.

[0017] A further configuration of the present invention is as follows: the base is fixed with a second guide rail, the second guide rail is slidably connected with a third slide block, the auxiliary positioning seat is installed on the third slide block, the base is provided with a T-slot, a T-slot bolt is embedded in the T-slot, the auxiliary positioning seat is provided with a through hole, and the T-slot bolt passes through the through hole and is threadedly connected to a locking nut.

[0018] By adopting the above technical solution, the positions of the third slide and the auxiliary positioning seat can be adjusted as needed using the T-slot and the bolts for the T-slot.

[0019] A further configuration of the present invention is as follows: the auxiliary positioning seat includes a base plate, a horizontal adjustment plate disposed on the base plate, and a vertical adjustment plate disposed on the horizontal adjustment plate. Both the horizontal adjustment plate and the vertical adjustment plate are provided with auxiliary positioning grooves. The horizontal adjustment plate has a horizontal strip hole, and the horizontal strip hole is provided with a first bolt threaded to the base plate. The vertical adjustment plate has a vertical strip hole, and the vertical strip hole is provided with a second bolt threaded to the base plate.

[0020] By adopting the above technical solution, the horizontal and vertical adjustment plates of the auxiliary positioning seat can be adjusted to their positions, making it easy to adjust according to the specific position of the side of the steering gear housing.

[0021] A further provision of the present invention is that the base is also provided with a driving member for driving the second slide to move.

[0022] The beneficial effects of this invention are:

[0023] 1. This invention innovatively adopts a structure of a first guide rail, a first slide block, and a lever dial indicator. The lever dial indicator measures the two mounting foot end faces of the steering gear housing, and the difference between the two readings is used to determine whether the parallelism of the two mounting foot end faces is qualified. The design is novel and the detection is fast and convenient.

[0024] 2. The position of the auxiliary positioning groove of the auxiliary positioning seat of the present invention can be adjusted as needed to meet the auxiliary positioning of steering gear housings of different specifications.

[0025] 3.
