Description

Technical Field

[0001] The present invention relates to a profiling fixture adapter, and more particularly to a connection structure for a profiling fixture. Background Art

[0002] A profiling fixture is a component designed to simulate the fitting degree when parts are connected. In edge detection, the profiling fixture generally makes corresponding simulation blocks according to data matching. At the same time, in order to stabilize the detection ability of the simulation blocks, a detection fixing structure corresponding to fixing the simulation blocks will be made.

[0003] Generally, a commonly used structure is made in the form of a hinge to realize the sliding of the simulation block to simulate vehicle loading. See Figure 1 , which is applicable to most vehicle models. However, with the continuous complexity of the part structure, the movement trajectory of the single hinge structure will interfere with the spatial structure of the part structure, making the simulation block that originally meets the design intention unable to move to the assembly position normally, and causing the fixture to lose the inspection function at some positions.

[0004] Therefore, how to design a connection structure for a profiling fixture adapted to complex part structures is a technical problem that urgently needs to be solved at present.

[0005] CN208205944U provides a fixture for the front door upper frame assembly of an automobile, which can solve the technical problems of low detection efficiency of the existing fixture and the inability to assemble the qualified components or the assembled dimensions not meeting the requirements. However, this technical solution still cannot be adapted to the connection structure of a profiling fixture for complex part structures. Summary of the Invention

[0006] The purpose of the present invention is to overcome the defects of the above-mentioned existing technologies and provide a connection structure for a profiling fixture, which optimizes the movement trajectory of the fixture fixing block and avoids inspection failure.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] The connection structure for a profiling fixture in the present invention includes a U-shaped plate, a first slider, a handle, a connecting plate and a second slider. Specifically:

[0009] The first slider is movably arranged in the U-shaped plate and can slide relatively along the length direction of the U-shaped plate;

[0010] The handle is arranged on the side wall of the first slider;

[0011] The connecting plate is connected to one end of the first slider, and a chute is arranged on the connecting plate;

[0012] One end of the second slider is movably connected to the sliding groove and can slide relatively along the length direction of the sliding groove. Its sliding direction is perpendicular to the sliding direction of the first slider, and the other end is fixedly connected to the profiling fixture.

[0013] Furthermore, mounting holes are provided on the second slider.

[0014] Furthermore, the profiling fixture is connected to the mounting hole by a bolt hole pin or a bolt connection.

[0015] Furthermore, a limiting block is provided on the side wall of the first slider.

[0016] Furthermore, a telescopic limiting member is provided on the U-shaped plate. When the telescopic limiting member extends, it can block and limit the horizontal displacement of the limiting block.

[0017] Furthermore, the telescopic limiting member includes a connecting arm and a telescopic member. The telescopic member can telescopically penetrate through the connecting arm and can block and limit the horizontal displacement of the limiting block when it extends.

[0018] Furthermore, a first screw hole is formed in the connecting arm.

[0019] Furthermore, the telescopic member includes an adjusting handle and a rod body;

[0020] External threads matching the internal threads of the first screw hole are provided on the rod body.

[0021] Furthermore, a second screw hole is formed in one end of the second slider movably connected to the sliding groove.

[0022] Furthermore, a limiting bolt is provided in the sliding groove. The limiting bolt penetrates through the sliding groove and is connected to the second screw hole.

[0023] Compared with the prior art, the present invention has the following technical advantages:

[0024] 1) In this technical solution, the connection structure for the profiling fixture changes the structure of the simulation block fixed block, decomposes the original single hinge movement into a combined movement mechanism with up and down and left and right directions respectively, and solves the problem of movement interference caused by space limitations.

[0025] 2) The structure of the profiling fixed block is changed, adding up and down movement in the Z direction and left and right movement in the Y direction. Different guides are provided for the two movement mechanisms respectively, and the movement space is outside the part installation position, so that there is no collision with the part, thereby optimizing the movement trajectory of the fixture fixed block and avoiding inspection failure.

[0026] 3) In this technical solution, the telescopic limiting member can limit the up-and-down movement in the Z direction, and the left-and-right movement in the Y direction is realized by tightening the limiting bolt, so as to lock all degrees of freedom, which can be adapted to high-strength profiling detection and has extremely high stability.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Embodiment 1

[0032] The connecting structure for the profiling fixture in this embodiment includes a U-shaped plate 1, a first slider 2, a handle 3, a connecting plate 4 and a second slider 5, see Figure 2 .

[0033] The first slider 2 is movably arranged in the U-shaped plate 1 and can slide relatively along the length direction of the U-shaped plate 1; the handle 3 is arranged on the side wall of the first slider 2. Specifically, when simulating the assembly, the operator holds the handle 3 with one hand to realize the position adjustment and connection assembly of the connecting structure, and the Z-direction adjustment of the first slider 2 can be realized through the holding adjustment of the handle 3.

[0034] A limiting block 21 is arranged on the side wall of the first slider 2. A telescopic limiting member is arranged on the U-shaped plate 1. When the telescopic limiting member extends, it can block and limit the horizontal displacement of the limiting block 21. The telescopic limiting member includes a connecting arm 6 and a telescopic member 7. The telescopic member 7 can telescopically penetrate through the connecting arm 6 and can block and limit the horizontal displacement of the limiting block 21 when extending. Specifically, a first screw hole 61 is opened on the connecting arm. The telescopic member 7 includes an adjustment handle 71 and a rod body 72. An external thread matching the internal thread in the first screw hole 61 is arranged on the rod body 72. A second screw hole is opened at one end where the second slider 5 is movably connected to the chute 41.

[0035] The connecting plate 4 is connected to one end of the first slider 2, and a sliding groove 41 is provided on the connecting plate 4. One end of the second slider 5 is movably connected to the sliding groove 41 and can slide relatively along the length direction of the sliding groove 41. Its sliding direction is perpendicular to the sliding direction of the first slider 2, and the other end is fixedly connected to the profiling fixture. An installation hole 51 is provided on the second slider 5. The profiling fixture is connected to the bolt hole of the installation hole 51 by a snap pin or a bolt connection.

[0036] In this embodiment, the connection structure for the profiling fixture changes the structure of the simulation block fixing block, decomposes the original single hinge movement into a combined movement mechanism with two directions of up and down and left and right respectively, and solves the problem of movement interference caused by space limitations. The structure of the profiling fixing block is changed to increase the up and down movement in the Z direction and the left and right movement in the Y direction. Different guides are provided for the two movement mechanisms respectively, and the movement space is outside the part installation position, so that there is no collision with the part, thereby optimizing the movement trajectory of the fixture fixing block and avoiding inspection failure.

[0037] A limit bolt 42 is provided in the sliding groove 41. The limit bolt 42 penetrates through the sliding groove 41 and is connected to the second screw hole. When the profiling position of the second slider 5 is adjusted, the profiling position is locked by tightening the limit bolt 42.

[0038] In this embodiment, the telescopic limit member can limit the up and down movement in the Z direction, and the left and right movement in the Y direction is realized by tightening the limit bolt 42, so as to lock all degrees of freedom, which can be adapted to high-strength profiling detection and has extremely high stability.
