Description

The workpiece roll-over table

Technical field

The utility model relates to a kind of turning device of workpiece.

Background technology

Under the prior art condition, big-and-middle-sized workpiece is overturn, normally realize through the tipping arrangement of special use, special-purpose reversal hanger, the method that perhaps relies on suspender and driving to match.The tipping arrangement of existing special use, reversal hanger, the structure more complicated costs an arm and a leg mostly; The operation and the service personnel that need specialty, number for the document of ZL200920143328.3 discloses a kind of electric turnover suspender, it comprises caliper unit and switching mechanism like Chinese patent; Switching mechanism comprises support, upset motor, a plurality of parts such as rotating shaft; Complex structure, complex operation; With the operation of overturning of suspender and the method that matches of driving, exist huge potential safety hazard.Through the rope knotting, let workpiece in the process that driving is sling, the center of gravity of workpiece is adjusted on the extended line of driving rope, thereby workpiece is tilted, and adjustment realizes standing up of workpiece step by step.Yet, in this process, often need people's augmented thrust; Workpiece usually can rotate, waves, impact etc. in the process of center-of-gravity position adjustment, easily operating personal is on every side damaged; Also can change because of center of gravity; Lack of equilibrium causes huge impact to suspender, driving and ground, has huge potential safety hazard.

Summary of the invention

The purpose of the utility model is to provide a kind of and can under the cooperation of driving or suspender, relies on the effect of workpiece self gravitation to realize overturning safely of workpiece, and simple in structure, easy to operate workpiece roll-over table.

In order to achieve the above object; The technical scheme of the utility model is: a kind of workpiece roll-over table, comprise stage body, and said stage body comprises first step and second step; Second step is lower than first step; Have the first workpiece placed cavity on the said first step, the first workpiece placed cavity has first gap towards the table top top of second step, has the second workpiece placed cavity on the said second step.

Side-lower away from first step of said second step also has the 3rd step; The 3rd step is lower than second step; The second workpiece placed cavity of second step has second gap towards the table top top of the 3rd step, has the 3rd workpiece placed cavity on the 3rd step.

The said first workpiece placed cavity is the circular break slot of smaller part, and the said second workpiece placed cavity is square or half-cylindrical break slot, and said the 3rd workpiece placed cavity is a circular counter bore.

Be lined with lumber layer or rubber pad in the said first workpiece placed cavity, the second workpiece placed cavity and the 3rd workpiece placed cavity.

Said stage body bottom has the connection convex edge.

After adopting said structure, because stage body comprises first step and second step, therefore; Can be according to the height of workpiece and the position of center of gravity, the height of appropriate design step and the horizontal throw of each step, the center of gravity that promptly guarantees workpiece is outside each step surface; Thereby rely on the effect of workpiece self gravitation, guarantee in the workpiece dropping process, realize 90 ° of (three steps of upset automatically; Turning 180 °), and fall the designated area.Owing to have the first workpiece placed cavity on the first step, has the second workpiece placed cavity on the second step again.Therefore, can guarantee workpiece in switching process, each step all falls into corresponding workpiece placed cavity, can not produce rotation, waves, impact phenomenon, can not injure operating personal on every side, and is safe and reliable.In addition, the utility model also has simple in structure, convenience operation, is specially adapted to batch manufacturing part shape, the similar upset station of size.

Description of drawings

Fig. 1 is the structural representation of the workpiece roll-over table of the utility model;

Fig. 2, Fig. 3, Fig. 4 are the application process scheme drawings of the utility model.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing does further detailed explanation to the utility model.

As shown in Figure 1; The workpiece roll-over table of the utility model comprises stage body 1, and said stage body 1 comprises first step 1-1 and second step 1-2; Second step 1-2 is lower than first step 1-1; Have the first workpiece placed cavity 1-1-1 on the said first step 1-1, the first workpiece placed cavity 1-1-1 has the first gap 1-1-2 towards the table top top of second step 1-2, has the second workpiece placed cavity 1-2-1 on the said second step 1-2.Two steps, turning 90 ° of workpiece.

As shown in Figure 1; In order to make 180 ° of workpiece upsets; The side-lower away from first step 1-1 of said second step 1-2 also has the 3rd step 1-3; The 3rd step 1-3 is lower than second step 1-2, and the second workpiece placed cavity 1-2-1 of second step 1-2 has the second gap 1-2-2 towards the table top top of the 3rd step 1-3, has the 3rd workpiece placed cavity 1-3-1 on the 3rd step 1-3.

As shown in Figure 1, in order to be fit to the upset of cylindrical work.The said first workpiece placed cavity 1-1-1 is the circular break slot of smaller part, and the said second workpiece placed cavity 1-2-1 is square or half-cylindrical break slot, and said the 3rd workpiece placed cavity 1-3-1 is a circular counter bore.

In order to prevent the workpiece of damaging in the switching process, be lined with lumber layer or rubber pad in the said first workpiece placed cavity 1-1-1, the second workpiece placed cavity 1-2-1 and the 3rd workpiece placed cavity 1-3-1.

As shown in Figure 1, for the ease of the utility model is fixed, said stage body 1 bottom has the convex edge 1-4 of connection.

Like Fig. 2,3, shown in 4, when the utility model was used for the switching process workpiece, can be arranged on top, workshop had in the ground or melt pit of driving.Workpiece 3 is under the lifting of driving 2; Winch on the first step 1-1 of the utility model; And workpiece 3 bottom surfaces are dropped in the first workpiece placed cavity 1-1-1, with the center of gravity of guaranteeing workpiece 3 not above first step 1-1, but above second step 1-2; But it is, as shown in Figure 2 relatively near first step 1-1.Then, operation driving 2 makes workpiece 3 downward, and workpiece 3 can slowly tilt, and this moment is operation driving 2 slowly, makes workpiece 3 in tilting procedure, the center of gravity of workpiece 3 all the time on the extended line of driving 2 ropes, prevent to drive a vehicle 2 receive transverse force effect.Workpiece 3 can slowly fall in the second workpiece placed cavity 1-2-1 on the second step 1-2 along design-calculated path of motion, and is as shown in Figure 3, at this moment, realized 90 ° of upsets of workpiece 3.Continue upset worker 3; The center of gravity of workpiece 3 is not above second step 1-2, but above the 3rd step 1-3, still comparison is near second step 1-2; Same slowly operation driving 2; Make workpiece 3 in tilting procedure, the center of gravity of workpiece 3 all the time on the extended line of driving 2 ropes, prevent to drive a vehicle 2 receive transverse force effect.Workpiece 3 can fall in the 3rd workpiece placed cavity 1-3-1 of the 3rd step 1-3 slowly along design-calculated path of motion, and the location, and is as shown in Figure 4, at this moment, accomplished 180 ° of upsets of workpiece 3.
