Description

TECHNICAL FIELD

[0001] The utility model relates to manual overhauling equipment technical field, concretely is overhauling operation platform. BACKGROUND

[0002] With the rapid development of manufacturing industry, the requirements for product quality and production efficiency are increasing. Large and complex workpieces, such as aerospace components, automobile engine key parts, precision mechanical parts, etc., in the machining process, deburring, welding slag and other irregular protrusions, surface polishing and maintenance are important links to ensure product precision, appearance quality, service life, product performance and safety.

[0003] With the continuous progress of industrial automation and intelligent technology, these traditional manual or semi-automatic operations are gradually being replaced by efficient and precise automated equipment and systems.

[0004] However, for some complex or high-precision workpieces, manual maintenance, polishing and deburring can achieve more delicate processing. This delicate operation is difficult to be completely replaced by machine automation, especially when dealing with details and corners, manual operation can rely on experience and flexibility to ensure that product quality and precision meet the requirements.

[0005] Moreover, there are various types of workpieces in manufacturing industry, with different shapes and materials. Manual maintenance, polishing and deburring can flexibly adjust the processing method and intensity according to the specific needs and characteristics of the workpiece, to meet the processing requirements of different workpieces, so the current manufacturing factory will retain the maintenance platform that can be manually operated.

[0006] In the current manufacturing factory, the maintenance operation platform is usually a large platform, which can rotate the workpiece for maintenance after clamping the workpiece. For large and complex-shaped workpieces, there may be a situation of unbalanced bilateral stress, which will exacerbate the difficulty of turning over. For this reason, the workpiece posture cannot be stabilized when it is fixed, so manual maintenance and polishing are prone to cause the workpiece to further deflect under stress, which is quite easy to cause damage to the workpiece and even cause safety accidents.

[0007] Therefore, in order to ensure that the maintenance operation platform can provide effective stability during operation, the present application provides a simple and easy-to-use maintenance operation platform. INVENTION CONTENTS

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0031] Please refer to Figures 1-4 The utility model provides the following technical scheme: a maintenance operation platform, which comprises a support 1 in the shape of a U, a jig 2 rotatably connected to the opposite faces on the upper part of the support 1, and a brake mechanism 3 on the support 1 for locking the turning angle of the support 1, and the jig 2 is provided with a counterweight mechanism 4.

[0032] As an optional embodiment of the utility model, after the two ends of the workpiece are fixed to the jigs 2 at the two ends of the support 1, the middle part of the U-shaped support 1 is completely open, so that the workpiece placed on the operation platform can expose enough surface, thus having more space for various maintenance operations. During maintenance, the jig 2 can be unlocked by the brake mechanism 3, so that the jig 2 and the workpiece on the jig 2 can be turned to a suitable angle for better maintenance operation by the operator, and after adjustment, the turning angle of the jig 2 can be locked again by the brake mechanism 3.

[0033] ​When the adjustment operation is performed, due to the existence of the counterweight mechanism 4, even when the workpiece is not in the center line of the two fixtures 2 due to its own irregular shape, the counterweight mechanism 4 can make the weight of the two ends of the fixture 2 similar, so that the gravity distribution of the fixture 2 and the workpiece as a whole is more uniform, which can make the stress of the fixture 2 more balanced when it is turned over, thereby reducing the difficulty of manually turning over the workpiece, and the imbalance of stress during the turning process is not prone to cause the entire operation table to fall, and when the turning angle of the workpiece is fixed by the brake module or during the maintenance operation, the stability of the workpiece, fixture 2 and support 1 as a whole will be stronger and safer.

[0034] Among them, for the fixture 2, different workpieces may require different functions and structures of the fixture 2, but in the embodiment, the fixture 2 only refers to the tool for mounting the workpiece, and is not limited to the specific structure;

[0035] The brake mechanism 3 mainly refers to a functional component with two states (i.e. locked state and unlocked state), the locked state refers to applying force to the fixture 2 to make the fixture 2 in a state of not being able to rotate, and the unlocked state is opposite to the locked state. In theory, any lock designed for the fixture 2 that can be controlled by instructions can be applied to the embodiment, so the specific structure of the brake mechanism 3 is not limited in the embodiment, and any existing technology that can be controlled by instructions to lock or unlock the fixture 2 is considered within the protection scope of the brake mechanism 3. Compared with the traditional manual locking method such as knob screw, the unlocking / locking method controlled by instructions is not only more convenient to use, but also more secure to lock the fixture 2, ensuring that various complex and irregular workpieces can be handled smoothly and safely during maintenance;

[0036] For the counterweight mechanism 4, it can be the form of adding counterweight blocks 41 to the vertical rod 43 as described below, or the form of adding counterweight blocks 41 to the container, but it should be understood that the counterweight mechanism 4 is generally considered as a common counterweight method, that is, by adding different number or weight of counterweight blocks 41 to adjust the total weight. As for the installation direction of the counterweight mechanism 4 on the fixture 2, since the shape and center of gravity of each workpiece is different, in order to make the center of gravity of the fixture 2 and the workpiece tend to be close to the center line of the fixture 2 and the height close to the position of the fixture 2 plate, the way to achieve this effect is actually many. Generally, counterweight blocks 41 can be added in different directions on each fixture 2, which can simply achieve the above technical purpose, and the position distribution and direction setting of the counterweight mechanism 4 are not limited in the embodiment.

[0037] Through the above structure, the maintenance operation platform with simple structure and convenient operation is provided, compared with the overturning mode of the existing operation platform, the fixing effect of the adjusted posture of the workpiece is more stable, the workman can ensure the smooth and safe maintenance process, and the production cost is obviously lower, and the maintenance process of the complex and irregular large workpiece is more easily adapted.

[0038] As shown in Figures 2-3 The counterweight mechanism 4 includes a counterweight block 41 and a lock piece 42 for fixing the counterweight block 41 on the jig 2.

[0039] As an optional embodiment of the utility model, when adjusting the gravity center of the workpiece, a proper number of counterweight blocks 41 can be selected and installed on the jig 2 according to the situation, and then the counterweight blocks 41 are fixed through the lock piece 42, so that the counterweight blocks 41 will not fall off when the workpiece is overturned.

[0040] As shown in Figures 2-3 The counterweight mechanism 4 further includes a vertical rod 43 fixedly connected to the jig 2, the counterweight block 41 is provided with a hole through which the vertical rod 43 passes, and the lock piece 42 is a nut and is threadedly connected to the vertical rod 43.

[0041] As an optional embodiment of the utility model, a relatively simple workpiece gravity center adjusting mode is provided, and the number and direction of the vertical rod 43 are not limited.

[0042] As shown in Figure 2 The vertical rod 43 includes at least two.

[0043] As an optional embodiment of the utility model, the two vertical rods 43 can prevent the counterweight block 41 from being self-deflected after being installed, thereby affecting the maintenance operation.

[0044] As shown in Figures 2-3 The jig 2 is provided with a clamping mechanism 21 for detachably connecting the workpiece.

[0045] As an optional embodiment of the utility model, the clamping mechanism 21 can directly adopt various technical means for fixing the workpiece in the prior art, such as a clamp, a screw, a buckle and the like, and the technical solution is not limited thereto, and it should be understood that the clamping mechanism 21 is replaceably arranged on the jig 2, so as to be adapted to different workpieces.

[0046] As shown in Figures 3-4 The jig 2 is rotatably connected to a bearing 12 in the support 1 through a main shaft 11.

[0047] As an optional embodiment of the utility model, the bearing 12 makes the rotation of the main shaft 11 on the support 1 more stable, and also reduces the operation difficulty when the workpiece is overturned.

[0048] As Figure 1 With Figure 4 As shown in the drawings, the brake mechanism 3 comprises a pneumatic brake 31 and a control module 32, the control module 32 controls the pneumatic brake 31 to operate to lock the main shaft 11, the control module 32 comprises one of a foot switch, a control panel, a button and the like, and the control module 32 synchronously controls two pneumatic brakes 31, and the pneumatic brake 31 is always open to be in a locked state.

[0049] As an optional embodiment of the utility model, the pneumatic brake 31 is a common prior art, which can clamp the main shaft 11 or contact the clamping of the main shaft 11 when controlled, and the technical scheme is suitable for the technical scheme because the specification of the pneumatic brake 31 is usually not large.

[0050] As Figure 1 As shown in the drawings, the control module 32 is a foot switch.

[0051] As an optional embodiment of the utility model, when the pneumatic brake 31 is controlled, the operator can step on the foot switch and manually turn the workpiece at the same time, which is more convenient to operate.

[0052] As Figures 1-4 As shown in the drawings, the support 1 is further provided with a driving mechanism 13 for driving the main shaft 11 to rotate, which comprises a hand wheel 131 and a speed reducer 132 connected in sequence, and the main shaft 11 is connected with the speed reducer 132.

[0053] As an optional embodiment of the utility model, the setting of the hand wheel 131 and the speed reducer 132 greatly reduces the labor intensity of manually turning the workpiece, and more importantly, the position of the hand wheel 131 is not in the space where the workpiece is located, so the above-mentioned foot switch can be placed in the space where the workpiece is not located, so that when the turning angle of the workpiece is adjusted, the worker is not easily injured due to the workpiece center of gravity being still unstable and turning too fast.

[0054] The working principle and use process of the utility model: after the two ends of the workpiece are fixed on the jigs 2 at both ends of the support 1, because the middle part of the U-shaped support 1 is completely open, the workpiece placed on the operation table can expose enough surface, so there is more space for various maintenance operations. During maintenance, the jig 2 can be unlocked by the brake mechanism 3, so that the jig 2 and the workpiece on the jig 2 can be turned to the appropriate angle for the operator to perform better maintenance operation, and after adjustment, the turning angle of the jig 2 can be locked again by the brake mechanism 3.

[0055] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
