Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the processing and positioning of the connection through hole on the intake flange of the existing exhaust manifold is unreliable, and the swing of the drill bit during drilling causes the flange to vibrate too much, which affects the processing accuracy and even causes the flange to be scrapped The purpose is to provide a connecting piece processing tool that can reduce vibration and solve the above problems

Embodiment 1

[0021] like figure 1 As shown, the connector processing tooling capable of reducing vibration of the present invention includes a base 1, on which a placing platform 2 is arranged, and the placing platform 2 is connected with a lifting mechanism 3, and the lifting mechanism 3 can drive the placing platform 2 to move, and the placing platform 2 Both sides are provided with hold-down device 4, and hold-down device 4 is provided with lead screw rod 5 through, and lead screw rod 5 is fixed on the base 1, and is provided with the nut 6 screwing with it on lead screw rod 5, and hold-down device 4 One end passes through the base 1 and can move along the axial direction of the lead screw 5, and the flange 11 is placed on the placement table 2, and the height of the placement table 2 can be adjusted through the lifting mechanism 3, so that the position of the flange 11 is more convenient for the drill bit to drill. hole, then move the compression device 4 along the lead screw 5, compre...

Embodiment 2

[0023] The present invention is based on embodiment 1, and the present invention is further described.

[0024] like figure 1 As shown, the present invention can reduce the vibration of the connecting piece processing tooling. The lifting mechanism 3 is a hydraulic lifting mechanism. The placement table 2 has played a supporting role, avoiding when drilling, the instability of the placement table 2 is easy to cause shaking or vibration, the stability of the placement table 2 is conducive to improving the precision of the drilling process, the lifting mechanism 3 is connected with the driving device 7, the driving device 7 drives the lifting of the lifting mechanism 3, and the drive device 7 can adopt a drive device commonly used in the prior art, such as a motor.

Embodiment 3

[0026] The present invention is based on embodiment 1, and the present invention is further described.

[0027] like figure 1 As shown, the present invention can reduce the vibration of the connecting piece processing tooling, the pressing device 4 is also provided with an auxiliary guide rod 8, the auxiliary guide rod 8 is parallel to the guide screw 5, and one end of the auxiliary guide rod 8 is fixed on the base 1 , the other end passes through the compression device 4, and the auxiliary guide rod plays a guiding role, making the movement of the compression device 4 more stable, avoiding the shaking of the compression device 4, and making the clamping effect of the compression device 4 on the flange better , the end of the auxiliary guide rod 8 away from the base 1 is provided with a limit block-9, the diameter of the limit block-9 is greater than the diameter of the auxiliary guide rod 8, and the effect of the limit block-9 is to prevent the auxiliary guide rod 8 from pres...

Abstract

The invention discloses a connecting part machining tool capable of reducing vibration. The connecting part machining tool comprises a base. A placement table is arranged on the base and connected with a lifting mechanism. The lifting mechanism can drive the placement table to move. Pressing devices are arranged on the two sides of the placement table. A guide screw is arranged on each pressing device in a penetrating manner. The guide screws are fixed to the base. Each guide screw is provided with a nut screwed with the guide screw. One end of each pressing device penetrates the base, and each pressing device can move in the axis direction of the corresponding guide screw. According to the connecting part machining tool, a flange is fixed among the placement table and the pressing devices, the flange is prevented from generating large vibration in the drilling process, drilling of a drill bit is more stable, and therefore the machining precision is improved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a connecting piece processing tool capable of reducing vibration. Background technique [0002] The exhaust manifold is connected to the cylinder block of the engine, and gathers the exhaust of each cylinder into the exhaust manifold, with divergent pipelines. Early automobile engines had low power per unit weight, low fuel combustion efficiency, and the exhaust gas temperature did not exceed 500°C. With the improvement of the efficiency of the automobile engine, the exhaust temperature is increased to 600-650°C. In recent years, the automobile exhaust emission standards have been continuously improved, and the application of catalytic technology and turbocharging technology has significantly increased the working temperature of the exhaust manifold, reaching above 750°C. With the further improvement of engine performance, the working temperature of the exhaust manifold will also incr...
