Description

Technical Field

[0001] The invention relates to the technical field of automobile parts detection, in particular to an adjustable clamp for precision automobile parts detection. Background Art

[0002] Auto parts testing is crucial in the automotive industry. There are many types of auto parts, including engine components, transmission system parts, brake system components, etc. The testing process requires the use of advanced technology and equipment to ensure that the quality of the parts meets strict standards. For example, the size of the parts is accurately measured by high-precision measuring instruments to ensure that it is within the tolerance range. At the same time, material analysis technology is used to test the material strength, hardness and corrosion resistance of the parts. Strict auto parts testing helps to improve the safety, reliability and performance of the car. Unqualified parts may cause the car to malfunction during driving, or even cause serious safety accidents. Testing can also promote automobile manufacturers to improve product quality and enhance market competitiveness. In the field of automobile maintenance, accurate parts testing can help technicians quickly diagnose problems, select suitable parts for replacement, and improve maintenance efficiency and quality. In short, auto parts testing is an indispensable part of the automotive industry. In the detection of auto parts, if the clamping mechanism cannot automatically adjust to adapt to parts of different sizes, it will bring many serious hazards.

[0003] Auto parts of different sizes require stable and appropriate clamping during the inspection process. If the clamping mechanism cannot adjust automatically, smaller parts may not be clamped firmly, and may easily shake or move during the inspection process, affecting the measurement accuracy. Larger parts may not be completely fixed, which will also cause deviations in the inspection data. For example, when inspecting the dimensional parameters of a car engine piston, inaccurate clamping may cause the measured diameter, height and other data to be inconsistent with the actual values, thereby affecting subsequent assembly and engine performance.

By setting the first support rod 3 and the fixed frame 41, the motor 42 can be connected to the lower surface of the panel 2. By setting the motor 42, after the power supply is connected and turned on, The first rotating rod 43 is caused to rotate, thereby causing the circular gear 44 to rotate. By setting the braking mechanism 5, a continuously increasing extrusion force can be applied to the precision automotive parts when the circular gear 44 rotates, thereby causing the clamping mechanism 6 to tightly clamp the precision automotive parts; the clamping mechanism 6 is fixedly connected to the side of the upper surface of the panel 2 away from the braking mechanism 5, and the clamping mechanism 6 includes an extrusion plate 61, and the extrusion plate 61 is located on the upper surface of the panel 2. The outer side surface of the extrusion plate 61 is fixedly connected to a connecting plate 63, and the outer surface of the connecting plate 63 is fixedly connected to a sliding rod 64, and the outer surface of the sliding rod 64 is sleeved with a limiting tube 6 5.

A threaded ring 55 is fixedly connected to the inner ring of the one-way bearing 54, and a reciprocating screw 57 is threadedly connected to the inner ring of the threaded ring 55. By arranging the threaded ring 55 on the inner ring of the one-way bearing 54, when the motor 42 rotates forward and the circular gear ring 56 rotates, the threaded ring 55 can rotate together, thereby causing the reciprocating screw 57 to move in the inner cavity of the threaded ring 55, and when the motor 42 reverses, the threaded ring 55 will not rotate, thereby causing the reciprocating screw 57 to not move. By arranging the reciprocating screw 57, when the threaded ring 55 rotates, the reciprocating screw 57 can move in the inner cavity of the threaded ring 55 and move during the movement.

When in use, after the precision auto parts are placed, the operator connects the motor 42 to the power supply and turns on the switch of the motor 42, so that the first rotating rod 43 and the circular gear 44 rotate. When the circular gear 44 rotates, it will mesh with the circular gear ring 56, thereby rotating the threaded ring 55. When the threaded ring 55 rotates, the reciprocating screw 57 rotates and drives the second rotating rod 58 to move in the direction of the clamping mechanism 6, and finally the push rod 513 moves in the inner cavity of the track ring 514, and the extrusion plate 61 at the end also moves.

When in use, in the process of the movement of the squeezing plate 61, due to the sliding action of the sliding rod 64 in the inner cavity of the limit tube 65, the squeezing plate 61 drives the first anti-skid plate 62 and the second anti-skid plate 611 to squeeze the outer surface of the precision automotive parts, and squeezes the other side of the precision automotive parts with the third anti-skid plate 614, and finally, when the squeezing plate 61 is continuously moving, the precision automotive parts are tightly clamped.

[0036] Working principle: The operator places the precision auto parts in the inner cavity of the placement frame 613. After placing the precision auto parts, the operator connects the motor 42 to the power supply and turns on the switch of the motor 42, so that the first rotating rod 43 and the circular gear 44 rotate. When the circular gear 44 rotates, it will mesh with the circular gear ring 56, thereby rotating the threaded ring 55. When the threaded ring 55 rotates, the reciprocating screw rod 57 rotates and drives the second rotating rod 58 to move toward the direction of the clamping mechanism 6, finally moving the push rod 513 in the inner cavity of the track ring 514, and also moving the extrusion plate 61 at the end; in the process of the movement of the extrusion plate 61, due to the sliding action of the sliding rod 64 in the inner cavity of the limiting tube 65, the extrusion plate 6 1 drives the first anti-slip plate 62 and the second anti-slip plate 611 to squeeze the outer surface of the precision auto part, and squeezes the other side of the precision auto part with the third anti-slip plate 614, and finally, when the squeezing plate 61 is continuously moved, the precision auto part is tightly clamped; after the precision auto part is clamped, the push rod 513 squeezes the squeezing ring 74, so that the end of the hexagonal rod 72 is inserted into the inner cavity of the hexagonal frame 77, and then the operator controls the motor 42 to flip, so that the rotating tube 71 rotates, and during the rotation process, the rotating block 76 and the bevel gear 78 rotate, and the bevel gear ring 712 rotates, and finally the anti-slip ring 714 drives the bottom end of the precision auto part to rotate, so as to achieve the effect of detecting the torque of the precision auto part.
