Description

Technical Field

[0001] The utility model belongs to the technical field of crankshaft processing, and in particular relates to a crankshaft processing stabilizing platform. Background Art

[0002] The crankshaft is the most important part of the engine. It bears the force from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine. The crankshaft is subjected to the combined effects of the centrifugal force of the rotating mass, the periodically changing gas inertia force and the reciprocating inertia force, which makes the crankshaft subject to bending and torsion loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surface must be wear-resistant, work evenly and have good balance.

[0003] There are many processes required for crankshaft processing, such as drilling and size detection. In order to better maintain the stability of the crankshaft during processing, the crankshaft needs to be fixed. However, when placing the crankshaft on the existing crankshaft processing stabilization table, the position of the fixture cannot be adjusted according to the length of the crankshaft, and only crankshafts of fixed specifications can be placed, resulting in poor feasibility. Therefore, an improved crankshaft processing stabilization table is designed. Utility Model Content

[0004] In view of the above-mentioned deficiencies existing in the prior art, the utility model provides a crankshaft processing stabilization table to solve the above-mentioned problems in the background technology.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A crankshaft machining stabilization table, comprising:

[0007] A base, wherein slide rails are arranged in parallel on the front and rear sides of the base;

[0008] The dynamic support frame and the first fixed support seat are arranged opposite to each other, and both the dynamic support frame and the first fixed support seat are equipped with clamps for clamping the crankshaft, wherein the dynamic support frame is slidably installed on the slide rail, and the first fixed support seat is fixedly installed on the base, and the dynamic support frame is slid to adjust the distance between the two clamps on the dynamic support frame and the first fixed support seat.

[0009] By adopting the above-mentioned structural design, the crankshaft processing stabilization table is provided with a slidable dynamic support frame and a fixed first fixed support seat, and a clamp for clamping the end of the crankshaft is provided on the dynamic support frame and the first fixed support seat. By sliding the dynamic support frame, the distance between the two clamps can be adjusted to adapt to crankshafts of different lengths.

[0010] Furthermore, the slide rail is a long block structure, the dynamic support frame is an arch structure, and a slide groove matching the slide rail is provided on the inner side of the bottom of the dynamic support frame.

[0011] Furthermore, a second fixed support seat is fixedly installed on the base, on the opposite side of the first fixed support seat, a support base plate is connected between the second fixed support seat and the first fixed support seat, and a telescopic support structure supporting the crankshaft is installed in the middle of the support base plate.

[0012] Furthermore, the width and height of the second fixed support seat are both smaller than the arched cavity of the moving support frame, so as to avoid the second fixed support seat interfering with the sliding of the moving support frame.

[0013] Further, the telescopic support structure comprises:

[0014] An internally threaded pipe sleeve, wherein the internally threaded pipe sleeve is fixedly connected to the supporting base plate, and a threaded lifting rod is connected to the internal thread of the internally threaded pipe sleeve;

[0015] The top of the threaded lifting rod is fixedly connected with a connecting head, and the connecting head is provided with a rotating rod;

[0016] The rotating seat is rotatably arranged on the top of the connector, and a V-shaped base supporting the crankshaft is arranged on the rotating seat. By adopting the above structural design, the telescopic support structure provides support for the crankshaft before it is clamped by the clamp. At the same time, the telescopic support structure has a lifting function. When in use, the crankshaft can be first placed on the V-shaped base and then the rotating seat can be rotated by the rotating rod to drive the threaded lifting rod to lift and lower, so that one end of the crankshaft on the V-shaped base can be aligned with the clamp on the first fixed support seat, and then the sliding support frame is close to the other end of the crankshaft and clamped by the clamp.

[0017] Furthermore, the clamp is a three-jaw chuck.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. The crankshaft processing stabilization table is provided with a slidable dynamic support frame and a fixed first fixed support seat, and a clamp for clamping the end of the crankshaft is provided on the dynamic support frame and the first fixed support seat, and the distance between the two clamps is adjusted by sliding the dynamic support frame to adapt to crankshafts of different lengths;

[0020] 2. The function of the telescopic support structure is to provide support for the crankshaft before it is clamped by the clamp. At the same time, the telescopic support structure has a lifting function. When in use, the crankshaft can be first placed on the V-shaped base and then the rotating seat is rotated by the rotating rod to drive the threaded lifting rod to lift and lower, so that one end of the crankshaft on the V-shaped base can be aligned with the clamp on the first fixed support seat, and then the sliding support frame is close to the other end of the crankshaft and clamped by the clamp.
