Description

Technical Field

[0001] This utility model relates to the field of welding machine technology, and in particular to a high-precision welding machine. Background Technology

[0002] Welding machines are processing equipment that use localized heating to join separate materials or parts into one piece. They are widely used in manufacturing, construction, aerospace and automobile manufacturing and other fields.

[0003] When welding plastic parts, an ultrasonic plastic welding machine is needed. An ultrasonic plastic welding machine is a professional device that uses high-frequency ultrasonic vibration to join plastic products. Its core principle is to generate local high temperature on the plastic contact surface through ultrasonic vibration, so that the material melts and is then fused under pressure. The welding strength is close to that of the original material, and no adhesive or large heat source is needed.

[0004] Conventional ultrasonic plastic welding machines are mostly simple support platforms. Workers place the plastic parts to be welded on the operating table, and the welding head contacts the parts. Under the action of the ultrasonic transducer, the welding operation is completed. However, the entire process still requires manual fixation of the parts, and the vibration acting on the parts can easily cause displacement or misalignment during welding. To address this, we have proposed a high-precision welding machine. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example Reference Figures 1-4 A high-precision welding machine includes a base 1, an operating table 29 for placing the parts to be welded is provided on the top of the base 1, a machine housing 3 is provided above the operating table 29, a welder is provided inside the machine housing 3, and a connecting seat 4 is installed on one side of the machine housing 3. A first pushing mechanism 2 is installed at the bottom of the connecting seat 4. The bottom of the first pushing mechanism 2 is fixed on one side of the top of the base 1 for lifting and lowering the welder above the operating table 29. In actual use, the first pushing mechanism 2 is a hydraulic cylinder, wherein the hydraulic station connected to the hydraulic cylinder is placed on one side of the welding machine.

[0019] Specifically, a control box 28 is installed on the side of the base 1 away from the first pushing mechanism 2. The control box 28 contains a controller, which is connected to the first pushing mechanism 2 via wires. In actual use, the controller is one of a PLC logic controller, a control motherboard, or a control host, used to control the operation of the welding machine. In addition, a touch screen display can be installed on the outer wall of the control box 28 for issuing control commands.

[0020] Among them, such as Figure 1 and Figure 3 As shown, the welding machine includes a housing 8. A linear motor 7 is mounted on top of the housing 8. The linear motor 7 is connected to a controller via wires. The slider of the linear motor 7 is fixed to the housing 8, and the slide rail of the linear motor 7 is mounted on a support plate 6. A second pushing mechanism 5 is vertically mounted on the top of the support plate 6 and is fixed to the inner wall of the housing 3. An ultrasonic transducer is installed inside the housing 8. The ultrasonic transducer and the second pushing mechanism 5 are both connected to the controller via wires. A welding head 9 is located at the bottom of the housing 8 and is connected to the ultrasonic transducer. In actual use, the second pushing mechanism 5 is a hydraulic cylinder or an electric push rod. One type of welding head 9 has a higher operating precision than the first pushing mechanism 2. Under the action of the second pushing mechanism 5, the welding head 9 can be adjusted more precisely. When in use, after placing the plastic part to be welded on the operating table 29, the welding head 9 can be adjusted to a position close to the part by the first pushing mechanism 2. Then, under the action of the second pushing mechanism 5, the welding head 9 is raised and lowered again to complete the contact between the welding head 9 and the part, so as to achieve welding. This not only improves the contact precision between the welding head 9 and the part in a limited space, but also makes it convenient to store the welding head 9 in the housing 3 when not in use, reducing the probability of the welding head 9 coming into contact with external objects and being damaged.

[0021] Furthermore, at least one guide shaft 10 is provided parallel to the side of the second pushing mechanism 5. The bottom of the guide shaft 10 is fixed to the support plate 6, and the top of the guide shaft 10 is fitted with a sleeve 11. The top of the sleeve 11 is fixed to the inner wall of the housing 3, providing guidance for the lifting and lowering of the welding head 9 and improving the lifting and lowering stability of the welding head 9.

[0022] like Figure 2 and Figure 4 As shown, the base 1 is a shell with an open top. The operating table 29 is fixedly installed on the top of the base 1. A first strip groove 12 is provided on the side of the operating table 29 away from the first pushing mechanism 2. A second strip groove 13 is also provided on one side of the operating table 29. The frontal projection of the second strip groove 13 is located on one side of the end of the first strip groove 12, and the second strip groove 13 is perpendicular to the first strip groove 12. A first lead screw 14 is provided inside the base 1. The first lead screw 14 is located below the first strip groove 12, and the end of the first lead screw 14 is rotatably connected to the inner wall of the base 1. A first drive mechanism is provided at the end of the first lead screw 14 away from the second strip groove 13. A first movable seat 18 is connected to the first lead screw 14 by a nut thread. The top of the first movable seat 18 passes through the first strip groove 12 and is connected to a first connecting plate 19. Several first strip plates 20 are installed on the side of the first connecting plate 19 at intervals. Under the rotation of the first lead screw 14, the first strip plates 20 can reciprocate linearly along the length direction of the first strip groove 12. The first drive mechanism includes a first gear 15 coaxially mounted on the first lead screw 14. A second gear 16 meshes below the first gear 15. A first drive motor 17 is mounted on the second gear 16. The first drive motor 17 is fixed to the inner wall of the base 1 by a bracket, and the first drive motor 17 is connected to a controller by a wire to provide power for the rotation of the first lead screw 14.

[0023] A second lead screw 21 is also provided inside the base 1. The second lead screw 21 is located below the second strip groove 13, and the end of the second lead screw 21 is rotatably connected to the inner wall of the base 1. A second drive mechanism is provided at the end of the second lead screw 21 away from the first lead screw 14. A second moving seat 25 is connected to the second lead screw 21 by a threaded nut. The top of the second moving seat 25 passes through the second strip groove 13 and is connected to a second connecting plate 26. Several second strip plates 27 are installed on the side of the second connecting plate 26 at intervals. Under the rotation of the second lead screw 21, the second strip plates 27 can reciprocate linearly along the length direction of the second strip groove 13. The second drive mechanism includes a third gear 22 coaxially mounted on the second lead screw 21. A fourth gear 23 meshes below the third gear 22.

The second drive motor 24 is fixed to the inner wall of the base 1 by a bracket, and the second drive motor 24 is connected to the controller by a wire to provide power for the rotation of the second lead screw 21.

[0024] Specifically, several second strip plates 27 are staggered with several first strip plates 20, that is, the ends of the second strip plates 27 are placed between two adjacent first strip plates 20, so that the first strip plates 20 and the second strip plates 27 do not affect each other when they move simultaneously, and can act on the adjacent edges of the component to calibrate and adjust the placement of the component on the operating table 29, ensuring the precise correspondence between the welding head 9 and the component position. During use, the worker's hands can be placed on the other two sides of the component to achieve multi-sided abutment and fixation of the component, ensuring the stability of the component. The movement of the strip plates also facilitates the adjustment of the welding position by hand, ensuring the full welding of the component.

[0025] It should be noted that the side walls of the first movable seat 18, the second movable seat 25, the inner walls of the first strip groove 12 and the second strip groove 13 are all smooth surfaces. The side wall of the first movable seat 18 is clearance-fitted with the inner wall of the first strip groove 12, and the side wall of the second movable seat 25 is clearance-fitted with the inner wall of the second strip groove 13. In addition to not affecting the movement between the first strip plate 20 and the second strip plate 27, the first strip plate 20 and the second strip plate 27 can be limited and supported to ensure the stability of the movement of the first strip plate 20 and the second strip plate 27.
