At this time, the positioning block The lowest end of the positioning block is flush with the lowest edge of the extrusion groove. As the positioning block is pushed in, the bottom end of the inner wall of the extrusion groove squeezes the positioning block until the positioning block is completely entered into the vertical groove. During this process, the spring is compressed. As the clamp head is pushed in, when the furniture head drives the positioning block to align with the positioning groove, the spring resets and pushes the positioning block to bounce into the positioning groove. Since the other side of the positioning block and the positioning groove is flat, when the clamp clamps the intermediate shell, the clamp head cannot move and remains in a stable state. Through the above-mentioned setting method, the damaged clamp head can be easily replaced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0028] Reference Figure 1-5 A support and adjustment device for detecting an intermediate housing of an automobile turbocharger comprises a workbench 1, an anti-reverse rotation mechanism is installed on one side of the bottom end of the workbench 1, and an adjustment mechanism is arranged at the center of the bottom end of the workbench 1, a horizontal slide groove 2 for sliding the adjustment mechanism is provided inside the workbench 1, and the adjustment mechanism comprises a clamp unit 3 slidably connected to the horizontal slide groove 2, and the clamp unit 3 is used to clamp or release the intermediate housing; the clamp unit 3 comprises a clamp seat 301, a clamp head 302, a limit plate 303, a positioning groove 304, a vertical groove 305, a spring 306, a positioning Block 307 and extrusion groove 308; the clamp head 302 can be detachably installed on the top of the clamp seat 301, the limit plate 303 is integrally formed with the two end surfaces of the clamp seat 301, the top surface of the clamp seat 301 is provided with the clamp seat 301 and the extrusion groove 308, the bottom end of the clamp head 302 is provided with a vertical groove 305 with an inverted cross-section of 180 degrees, the inner wall of the vertical groove 305 is slidably connected with a positioning block 307, the lower half of the positioning block 307 is consistent with the positioning groove 304, and a spring 306 is connected between the top of the positioning block 307 and the top of the inner wall of the vertical groove 305.

[0029] When measuring the intermediate housing (such as laser measurement), the intermediate housing needs to be gradually moved to prevent it from moving. By starting the anti-reverse rotation mechanism, the anti-reverse rotation mechanism drives the adjustment mechanism, and the clamp unit 3 on the adjustment mechanism clamps the intermediate housing;

[0030] When the fixture head 302 is worn out during long-term use, it is necessary to replace the fixture head 302. By pushing the fixture head 302 to move toward the center of the workbench 1, the fixture head 302 drives the positioning block 307 to move synchronously when the force is applied to the fixture head 302. At this time, the inclined surface of the positioning block 307 and the inclined surface of the positioning groove 304 squeeze each other, and the positioning block 307 subjected to the extrusion reaction force moves upward along the vertical groove 305. At this time, the spring 306 is compressed until the positioning block 307 is misaligned with the positioning groove 304. By continuously pushing the fixture head 302 to move, it can be disassembled.

[0031] Then, the new clamp head 302 is docked with the clamp seat 301, and the new clamp seat 301 is pushed outward. At this time, the lowest end of the positioning block 307 is flush with the lowest edge of the extrusion groove 308. As the positioning block 307 is pushed in, the bottom end of the inner wall of the extrusion groove 308 squeezes the positioning block 307 until the positioning block 307 is completely entered into the vertical groove 305. During this process, the spring 306 is compressed. As the clamp head 302 is pushed in, when the furniture head 302 drives the positioning block 307 to align with the positioning groove 304, the spring 306 is reset at this time, pushing the positioning block 307 to bounce into the positioning groove 304. Since the other side of the positioning block 307 and the positioning groove 304 is a plane, when the clamp 302 clamps the intermediate shell, the clamp head 302 cannot move and remains in a stable state.

[0032] Through the above arrangement, the damaged clamp head 302 can be easily replaced.

[0033] The anti-reverse rotation mechanism includes a forward and reverse motor 10 installed on one side of the bottom of the workbench 1 through a mounting frame, the output end of the forward and reverse motor 10 is connected to a worm 9, the outer periphery of the worm 9 is meshed with a worm wheel 8, and a driving gear 7 is installed at the top center of the worm wheel 8 through a synchronous shaft, and the driving gear 7 is meshed with the adjustment mechanism.

[0034] By starting the forward and reverse motor 10, the forward and reverse motor 10 drives the worm 9 to rotate. When the worm 9 rotates, the spiral part of its outer circumference squeezes the tooth part of the worm wheel 8. At this time, the worm wheel 8 rotates by itself. The rotating worm wheel 8 drives the driving gear 7 to rotate through the synchronous shaft;

[0035] It should be noted that: since the worm 9 can drive the worm wheel 8 to rotate, the worm wheel 8 cannot reversely drive the worm 9 to rotate, after the clamp unit 3 clamps the intermediate housing, it can remain in the clamped state to prevent the clamping loosening phenomenon.

[0036] The adjusting mechanism includes a passive gear 4 meshing with a driving gear 7 , an arcuate slot 5 is provided inside the passive gear 4 , a movable column 6 is movably connected inside the arcuate slot 5 , and the top of the movable column 6 is fixedly connected to the top of the clamp seat 301 .

[0037] The rotating active gear 7 drives the passive gear 4 to rotate, and the passive gear 4 drives the arc-shaped slide groove 5 thereon to perform synchronous action when rotating. The inner wall of the arc-shaped slide groove 5 squeezes the movable column 6 during the action, and the movable column 6 drives the clamp unit 3 to move along the horizontal slide groove 2 under pressure. The clamp units 3 moving toward each other can clamp the intermediate shell, and the clamp units 3 moving away from each other can release the clamping of the intermediate shell.

[0038] The top of the passive gear 4 is integrally formed with a rotating ring 11 rotatably connected to the workbench 1. The bottom of the workbench 1 is provided with an annular groove for the rotating ring 11 to rotate. The cross-section of the rotating ring 11 and the annular groove is an inverted 180-degree "convex" structure.

[0039] The rotating groove provides a rotating support for the rotating ring 11 , thereby preventing the driven gear 4 from being loosened.

[0040] The interior of the workbench 1 is provided with limiting grooves 12 on both sides of the horizontal slide groove 2 , and the limiting grooves 12 are provided for the limiting plates 303 to slide.

[0041] The limiting plate 303 moves with the clamp seat 301 . At this time, the limiting plate 303 slides along the limiting groove 12 , so that the clamp seat 301 can be kept at a preset height to prevent the clamp seat 301 from falling.

[0042] The bottom end of the inner wall of the extrusion groove 308 is an inclined surface, the end of the inner wall bottom of the vertical groove 305 that is aligned with the outer end of the clamp seat 301 is the low point, and the other end of the inner wall bottom of the vertical groove 305 located inside the clamp seat 301 is the high point, and the vertical distance between the low point and the high point is equal to the height of the positioning groove 304.

[0043] When the positioning block 307 slides into the extrusion groove 308 , the inclined surface at the bottom end of the inner wall of the extrusion groove 308 can apply an extrusion force to the positioning block 307 , so that the positioning block 307 completely enters the vertical groove 305 .

[0044] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
