Background Art

[0002] Mechanical components, also called mechanical parts, are the inseparable individual parts that make up machinery and machines. During the processing of mechanical components, in order to maintain the stability of the mechanical components, it is necessary to use fixing devices to fix the mechanical components.

[0003] The patent document with application number 2021223272595 discloses a component fixing fixture based on mechanical electronics, which drives the installation box to slide by pushing the electric push rod and drives the push plate to slide by the limit electric push rod. The side end of the circuit board fits with the side end of the scale sliding plate, and the circuit board is quickly supported and limited, so that the electronic components can be stably supported and limited during welding, avoiding the position displacement of the circuit board due to the touch of the mechanical arm during welding, and ensuring the stability during welding. Since the fixing fixture needs to realize the rapid limitation and support of the components by pushing the electric push rod and the limit electric push rod, the operation is relatively cumbersome and relies on the assistance of the electromagnet and the slider, which affects the accuracy of the component position. The device also requires manpower to realize the clamping and loosening functions, and the processing efficiency is low, resulting in low automation level and operation efficiency.

[0004] Patent document with application number 2020214669568 discloses a mechanical electronic engineering mechanical component fixing device, such as Figure 1 It comprises a base 1, two symmetrically arranged support plates 4 are fixedly connected at both ends of the upper surface of the base 1, one side of one support plate 4 is fixedly connected to one end of a support block 13, and the other end of the support block 13 is fixedly connected to one side of another support plate 4, a groove is provided on the surface of the support block 13, and a wire mesh 10 is fixedly connected to the surface of the support block 13 just above the groove, a rotating rod 12 is rotatably connected to the middle of the upper surface of the base 1, and the upper end of the rotating rod 12 passes through the support block 13 and is fixedly connected to a workbench 11, and the two support A slide plate 9 is fixedly connected to the upper sides of the relative inner sides of the plate 4 through a moving mechanism, a U-shaped block 19 is fixedly connected to the lower end of the slide plate 9, a turntable 17 is rotatably connected inside the U-shaped block 19, a pressure plate 18 is fixedly connected to the lower end of the turntable 17 through a connecting column, a bolt through hole is provided on one side of the U-shaped block 19, a locking bolt 20 is connected to the inner thread of the bolt through hole, and one end of the locking bolt 20 is in contact with the surface of the turntable 17, a blower mechanism is provided at one end of the upper surface of the base 1, and support legs are fixedly connected to the four corners of the bottom of the base 1.

[0005] The device can make the pressing plate contact with the step surface or inclined surface of the irregular component by rotating the workbench and adjusting the angle of the pressing plate, so that the step surface or inclined surface of these irregular mechanical components can be pressed, thereby improving the fixing effect of the mechanical components. However, since the workbench needs to be rotated and the angle of the pressing plate needs to be adjusted, the operation is complicated and may be cumbersome, and there is a lack of automatic clamping function, especially for irregular components. The clamping ability is poor, which reduces the fixing effect and work efficiency.

[0006] When using traditional mechanical component fixing devices, the clamping and loosening of mechanical components require manual operation, which not only wastes manpower and is inefficient, but also wastes a lot of time, resulting in reduced processing efficiency of mechanical components.

During this period, the lower end of the double-sided rack contacts the inclined surface on the upper side of the fixed ring, driving the double-sided rack to move, and then driving the gears on both sides to rotate. The gears on both sides drive the corresponding single-sided rack to move, so as to drive the L-shaped plates on both sides to move, so that the two L-shaped plates on one side move down to complete the clamping action, and the two L-shaped plates on the other side move up to release the clamping of the mechanical components, and perform the clamping and loosening of the automated components, thereby reducing the time wasted in loading and unloading components and improving the processing efficiency.

[0028] The rotating rod 2 is arranged on the upper surface of the bottom shell 1, and a motor 3 is fixedly arranged inside the bottom shell 1, and the output end of the motor 3 is fixedly connected to one end of the rotating rod 2; a fixing ring 8 is fixedly arranged on the upper surface of the bottom shell 1, and the fixing ring 8 is concentrically arranged with the rotating rod 2; a transverse plate 4 is fixed on the upper side of the rotating rod 2, and both sides of the upper surface of the transverse plate 4 are connected to a rectangular fixed shell 5; a through hole (not marked in the figure) is provided in the middle of the lower transverse arm of the fixed shell 5 and at the position of the transverse plate 4 closely attached thereto, and openings are provided on both sides of the fixed shell 5, and the outer sides of the two openings are closely attached to the L-shaped plate 6.

[0029] The double-sided rack 7 is located inside the fixed shell 5, and its upper end is connected to the upper cross arm of the fixed shell 5 through the fixed rod 14, and the lower end is in contact with the fixed ring 8 through the lower cross arm of the fixed shell 5 and the through hole of the cross plate 4. At the same time, the lower end edge is a rounded surface to prevent damage to the fixed ring 8; a spring 15 is provided on the movable sleeve of the rod wall of the fixed rod 14, and the two ends of the spring 15 are respectively fixedly connected to the corresponding double-sided rack 7 and the inner wall of the fixed shell 5, so as to facilitate the downward movement and reset of the double-sided rack 7; the cross section of the fixed rod 14 is square, so that the double-sided rack 7 cannot rotate, that is, it can slide stably; the double-sided rack 7 is meshed and arranged between two gears 13. The gear 13 meshes with the single-sided rack 10 on one side close to the L-shaped plate 6, and a connecting block 9 is fixedly provided on the lower side of the single-sided rack 10. One side of the connecting block 9 is fixedly connected to the corresponding L-shaped plate 6.

[0031] During operation, the mechanical element is placed on the upper surface of the fixed shell 5, and then the power supply of the motor 3 is turned on. The motor 3 drives the transmission rod 12 to rotate, so that the horizontal plate 4 drives the two fixed shells 5 to rotate, and drives the lower end of the double-sided rack 7 to collide with the inclined surface on the upper side of the fixed ring 8, so that the inclined surface squeezes the double-sided rack 7 to move, and then drives the gears 13 on both sides to rotate. The gears 13 on both sides then drive the corresponding single-sided rack 10 to move, so that the L-shaped plates 6 on both sides move up and down, and the maximum upward movement distance is when the gear 13 reaches the upper cross arm of the fixed shell 5, and the maximum downward movement distance is to the limit connection block 9. The limit rod 11 passes through the connection block 9 to maintain stability. Through the up and down movement of the L-shaped plate 6, the automatic clamping and loosening of the mechanical element to the element is completed, that is, when the L-shaped plates 6 on both sides move downward, they move to cooperate with the fixed shell 5 to clamp the mechanical element, and when they move upward, they release the clamping of the mechanical element. This automatic clamping can reduce the time waste of loading and unloading components and improve processing efficiency.
