Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a jig for conveniently taking out workpieces. Background Art

[0002] At present, during the use of existing jigs, workers first place the loose workpieces on the working platform with clamping components. After the clamping components clamp the workpieces, assembly or welding operations are started. After the operations are completed, the workpieces are taken off the working platform and placed on the finished product rack. When taking out the workpieces, the clamping components are first opened and then the workpieces are taken out.

[0003] However, after the clamping components are opened, the vertices of the clamping components are usually relatively high and there are relatively sharp corners at the top. To take out the workpieces, workers need to lift the workpieces so that the bottom surface is not lower than the vertices of the clamping components before taking them out. During the actual production and use process, the lifted height is not easy to control. The sharp corners at the top of the clamping components often scratch the workpieces, and the clamping components catch the workpieces, resulting in damage to the workpieces and sometimes even causing workers to fall and get injured, and safety accidents also occur frequently. Summary of the Utility Model

[0004] In order to solve the above technical problems, on the basis of the original working platform, the utility model adds a jig for conveniently taking out workpieces.

[0005] A jig for conveniently taking out workpieces specifically includes: a working platform on which workers perform assembly or welding operations; several clamping components are arranged on the working platform; a support component is arranged inside the working platform; a moving bracket is arranged on the support component and slides up and down along the support component; a lifting arm is connected to the moving bracket, the lifting arm is arranged above the working platform and in the gap between the clamping components without interfering with the clamping components; the support component and the moving bracket are connected by a driving component.

[0006] The effect is that when workers take out the workpieces, the clamping components do not interfere with the workpieces, thus avoiding the situation that the jig scratches the workpieces and the jig catches the workpieces, resulting in damage to the workpieces and workers falling and getting injured.

[0007] Further, guide wheels are arranged on the moving bracket and move down along the support component.

[0008] The effect is that the moving bracket moves in a straight line along a fixed track, ensuring that the lifting arm does not interfere with the clamping components every time it operates.

[0009] Further, a limiting component is also arranged on the support component.

[0010] The effects are as follows: ensuring that the moving support does not break away from the supporting component under any circumstances, improving the safety of the equipment and enhancing the stability.

[0011] Furthermore, a base is also provided at the bottom of the supporting component.

[0012] The effects are as follows: the working platform can be separated independently to perform operations alone, improving the adaptability of the equipment and increasing the expandability of the equipment.

[0013] Furthermore, a flow bar is also provided on the lifting arm, and a number of rollers are provided on the flow bar.

[0014] The effects are as follows: Workers only need to gently push the workpiece, and it can slide out along the flow bar, which greatly reduces the action of workers lifting heavy objects, reduces the risk of injury, and greatly reduces the labor intensity of workers. It speeds up the operation speed, improves work efficiency, and also enhances safety; at the same time, the structure of the flow bar is adopted, which has a long service life, is convenient to replace, and is easy to maintain.

[0015] Beneficial effects

[0016] On the basis of not changing the original working platform, the present utility model adds a structure for lifting and translation, makes full and reasonable use of the space of the platform clamping component, has a compact structure, is simple and practical, reduces the labor intensity of workers, and improves safety.

[0024] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described.

[0025] As Figure 1 shown, a fixture for conveniently taking out workpieces includes an operation platform 1 on which workers perform assembly or welding operations, and a plurality of clamping components are arranged on the operation platform 1; as Figure 4 shown, when workers perform operations on the operation platform, the clamping components are in a closed state; as Figure 5 shown, after the operation is completed, the clamping components are in an open state.

[0026] The first embodiment of the present invention:

[0027] The described fixture for conveniently taking out workpieces includes a support component 2 arranged on one side of the operation platform 1; a movable bracket 3 that can move up and down is arranged inside the support component 2; the support component 2 is connected to the movable bracket 3 through a driving component 5; a lifting arm 4 is arranged on the sliding platform 3, and the lifting arm 4 is arranged above the operation platform 1 and is located at the gap between the clamping components without interfering with the clamping components.

[0028] When not working, the lifting surface of the lifting arm is lower than the bottom surface of the workpiece, which does not affect the normal operation of the operation platform; when working, that is, when the workpiece needs to be taken out, the driving component lifts the lifting arm, so that the workpiece is lifted, and the bottom surface of the lifted workpiece is higher than the vertex of the opened fixture, and the worker lifts the workpiece upward and takes it out and places it on the finished product rack.

[0029] The second embodiment of the present invention:

[0030] The support component 2 is independently arranged on one side of the operation platform. As Figure 2 shown, a base 21 is further arranged at the bottom of the support component 2, and the base 21 extends in the direction of the lifting arm and can be placed at the bottom of the operation platform to ensure the stability of the entire mechanism.

[0031] The operation platform 1 can be separated and operate independently, improving the adaptability of the fixture and increasing the expandability of the fixture.

[0032] Guide wheels 33 are installed on both sides of the movable bracket 3, and the guide wheels 33 move up and down along the support component 2.

[0033] A limiting component 22 is further arranged inside the support component 2, and the limiting component 22 is used to limit the upper limit position of the upward movement of the movable bracket 3.

[0034] The limiting component 22 is an upward convex block, and the convex block is on the extension line of the movement track of the guide wheel.

[0035] The lifting arm 4 can move left and right on the moving bracket 3. After the position of the clamping component changes, the position of the lifting arm 4 can be easily adjusted, facilitating the adjustment.

[0036] A flow bar 7 is also installed on the lifting surface 6 of the lifting arm 4.

[0037] When the worker takes out the workpiece, there is no need to lift it forcefully upwards. The workpiece can be translated to the outside of the fixture and then supported, and placed on the finished product rack. Such operation is more labor-saving and reduces the labor intensity.

[0038] If the workpiece is a plastic part, the rollers 8 on the flow bar 7 can be made of nylon or rubber to prevent scratching the workpiece.

[0039] If the workpiece is a metal part or the workpiece is heavy, the rollers on the flow bar 7 are made of steel wheels. The steel rollers can prevent the workpiece from crushing the flow bar 7 and improve the stability of the equipment.

[0040] As Figure 3 shown, a joint 51 is also provided at one end of the driving component 5, and an ear seat 31 is provided on the moving bracket 3. The joint 51 and the ear seat 31 are hinged by a hinge shaft 32.
