Description

Technical Field

[0001] This utility model relates to the field of precision parts processing technology, specifically a welding auxiliary device for processing precision mechanical parts. Background Technology

[0002] Precision component machining and welding is a composite process that combines high-precision machining with professional welding technology. Its core is to achieve reliable connection of components while ensuring the dimensional accuracy and structural strength of the components.

[0003] In existing methods for machining control components of machinery, components need to be welded onto a control substrate. During the welding process, a positioning auxiliary device is required. Most current positioning auxiliary devices are simple carrier plates; the substrate is placed directly into the limiting groove of the carrier plate, and then pressure is applied to the substrate surface to achieve positioning. This is not convenient for positioning substrates of different sizes. Therefore, we propose a welding auxiliary device for the machining of precision mechanical parts. Utility Model Content

[0004] The purpose of this invention is to provide a welding auxiliary device for the processing of precision mechanical parts, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding auxiliary device for processing precision mechanical parts, comprising a base, a fixing plate fixedly installed at the top center of the base, adjusting plates connected to both sides of the top of the fixing plate, a carrier plate installed on both sides of the top of the adjusting plate, a limiting notch opened at the top of the carrier plate, and a negative pressure suction cup fixedly installed on the inner wall of the limiting notch; The top of the fixed plate is provided with a first sliding groove, and the inner cavity of the first sliding groove is equipped with a first adjustment component for adjusting the movement of the adjustment plates on both sides.

[0006] By adopting the above technical solution, the device is first installed at the place of use. Then, according to the size of the board, the first adjustment component is activated to adjust the distance between the two adjustment plates. Then, the adjustment plates adjust the distance between the two side carrier plates to adapt to the size of the substrate. Then, the substrate is placed on the four carrier plates to achieve the positioning of the substrate. At the same time, the negative pressure suction cup is used to adsorb the substrate, thereby achieving effective limiting of the board, which is beneficial to improving the stability of the substrate and thus ensuring the accuracy of welding on the substrate. At the same time, the device has strong adaptability.

[0007] In a preferred embodiment of the present invention, the first adjustment component includes a first dual-axis motor, which is fixedly installed in the middle of the inner cavity of the first slide groove. Both ends of the first dual-axis motor are fixedly connected to a first lead screw. The outer end of the first lead screw is rotatably connected to the inner wall of the first slide groove. A suitable first lead screw slider is fitted on the outer wall of the first lead screw. The top of the first lead screw slider is fixedly connected to the corresponding adjustment plate.

[0008] By adopting the above technical solution, the first dual-axis motor drives the first lead screws on both sides to rotate, thereby driving the first lead screw sliders on both sides to move, thereby adjusting the distance between the two adjustment plates to adapt to the width of the substrate.

[0009] In a preferred embodiment of this utility model, the top of the adjusting plate is provided with a second sliding groove, a second dual-axis motor is fixedly installed in the middle of the inner cavity of the second sliding groove, and a second lead screw is fixedly connected to both ends of the second dual-axis motor. The outer end of the second lead screw is rotatably connected to the inner wall of the second sliding groove, and a matching second lead screw slider is fitted on the outer wall of the second lead screw. The top of the second lead screw slider is fixedly connected to the carrier plate.

[0010] By adopting the above technical solution, the second dual-axis motor can drive the second lead screw to rotate, thereby driving the second lead screw slider to move, thereby adjusting the distance between the two carrier plates, so as to adapt to the length of the substrate.

[0011] In a preferred embodiment of this utility model, the side wall of the adjusting plate is connected to a limiting component. The limiting component includes a base plate, which is fixedly connected to the adjusting plate. A side plate is fixedly installed on the top of the base plate. An electric push rod is fixedly installed on the outer wall of the side plate. The push rod of the electric push rod movably passes through the side plate and is fixedly connected to a movable plate. A movable plate is provided on the outer wall of the movable plate. An inclined surface is provided at the bottom of the movable plate. Limiting grooves are provided on both sides of the outer wall of the movable plate. A matching limiting slider is inserted into the inner cavity of the limiting groove. The outer wall of the limiting slider is fixedly connected to the movable plate. A spring is fixedly connected to the top of the limiting slider. The outer end of the spring is fixedly connected to the top of the inner cavity of the limiting groove.

[0012] By adopting the above technical solution, when the electric actuator moves the moving plate and clamps the side wall of the substrate, the substrate will contact the bottom inclined surface of the movable plate to achieve clamping. During the clamping process, the spring pushes the limiting slider, so that the movable plate has a downward pressing force on the substrate, thereby improving the stability of the substrate.

[0013] In a preferred embodiment of this utility model, limit rods are fixedly installed on both sides of one side wall of the movable plate, and the limit rods movably pass through the side plate.

[0014] In a preferred embodiment of this utility model, mounting holes are provided at the four corners of the top of the base.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The present application provides a welding auxiliary device for processing precision mechanical parts. The first adjustment component can drive the adjustment plate to move, and then the adjustment plate can drive the carrier plates on both sides to move, thereby adjusting the four carrier plates to adapt to the size of the substrate, which is beneficial to improving the adaptability of the device. Furthermore, when the load is limited, the negative pressure suction cup can be used for adsorption, which is beneficial to improving the stability of the substrate. The limiting components can clamp and limit the two sides of the board, which helps to improve the stability of the board. During clamping and positioning, they can generate a downward force on the board, which makes the board and the negative pressure suction cup fit together, thus further improving the stability of the substrate.

Then, the adjustment plates adjust the distance between the two side carrier plates 24 to accommodate the size of the substrate. Then, the substrate is placed on the four carrier plates 24 to achieve the positioning of the substrate. At the same time, the negative pressure suction cup 25 is used to adsorb the substrate, thereby achieving effective limiting of the board, which is beneficial to improving the stability of the substrate and thus ensuring the accuracy of welding on the substrate.
