Description

Technical Field

[0001] The utility model relates to the field of welding, in particular to a limiting structure for an automatic welding tool for an internal frame of a B-ultrasound machine. Background Art

[0002] Most of the parts in the internal frame of the product are thin plates of 2 mm or less. When welded on a traditional workbench, they are greatly deformed and sized. It is difficult to reshape them after welding, and the cost is high. The actual parameters of the welded parts are greatly different from the standard size due to shrinkage, and after reshaping, they cannot meet the customer's requirements for product accuracy. Manual welding has unstable welding quality and low welding speed, which is not suitable for mass production.

[0003] Therefore, in order to solve this problem, a solution is proposed, patent number: 2023231899846, patent name: an automatic welding tool for the internal frame of an ultrasound machine. However, when this solution is actually used, the operator finds that during the welding process, the internal frame of the ultrasound machine is subjected to high temperature, which causes the entire internal frame to expand upward and cause slight displacement, which ultimately leads to the inability to align the welding points and poor welding effect. This application proposes a solution to this problem. Summary of the invention

[0004] Purpose of the utility model: The purpose of the utility model is to provide a limiting structure for the automatic welding tooling of the internal frame of the ultrasound machine, which can press the internal frame of the ultrasound machine to prevent the internal frame of the ultrasound machine from being displaced due to thermal expansion during welding and causing poor welding effect.

[0005] Technical solution: The utility model describes a limiting structure for an automatic welding tooling for the internal frame of an ultrasound machine, comprising a T-shaped pressure plate, a connecting piece and a driving module. The driving module is connected to a No. 2 L-shaped bracket in the automatic welding tooling for the internal frame of an ultrasound machine by bolts. One end of the connecting piece is connected to the driving module, and the other end is connected to the T-shaped pressure plate. The T-shaped pressure plate is arranged above the No. 2 L-shaped bracket, and the lower end face of the T-shaped pressure plate faces the top end face of the internal frame of the ultrasound machine to be welded. The output end of the driving cylinder in the driving module is connected to the horizontal axis in the connecting piece to drive the horizontal axis to rotate.

[0006] Preferably, the horizontal arm of the T-shaped pressing plate is not longer than the axial length of the internal frame of the B-ultrasound machine, and the vertical arm of the T-shaped pressing plate is fixedly connected to the connecting piece.

[0007] The length of the cross arm does not exceed the axial length of the internal frame of the ultrasound machine, which can ensure that the cross arm exerting pressure on the internal frame of the ultrasound machine does not affect the settings of other equipment and will not affect the work of other equipment components.

[0008] Preferably, the connecting member includes a connecting rod, a Y-shaped arm and a transverse axis. The connecting rod is connected to the T-shaped pressure plate by bolts. The Y-shaped arm is connected to one end of the connecting rod facing the driving module. A transverse axis is fixedly connected between the two arms of the Y-shaped arm, and the transverse axis is rotatably connected to the driving module.

[0009] Preferably, the length of the connecting rod is not less than half the length of the vertical arm in the T-shaped pressure plate.

[0010] The length of the connecting rod is not less than half of the length of the vertical arm in the T-type pressure plate, which can ensure that the force transmitted to the T-type pressure plate through the connecting piece can be transmitted more efficiently, reduce the strength requirements of the connecting rod and the vertical arm, and improve the service life.

[0011] Preferably, the connecting rod is welded to the Y-shaped arm or is integrally formed therewith.

[0012] Preferably, the driving module includes a driving cylinder and a connecting plate, the driving cylinder is fixedly connected to the connecting plate by bolts, and the connecting plate is connected to the side end face of the second L-shaped bracket by bolts.

[0013] Preferably, a positioning block is provided on the top of the connecting plate, and the positioning block is fitted and connected to the top end surface of the second L-shaped bracket.

[0014] The fitting connection between the positioning block and the No. 2 L-shaped bracket can reduce the stress strength of the bolts connecting the connecting plate and the No. 2 L-shaped bracket, which improves the stability of the connection on the one hand and the overall service life on the other.

[0015] Beneficial effects: Compared with the prior art, the utility model has the following advantages:

[0016] The present application solves the problem that the internal frame of an ultrasound machine is easily displaced due to expansion of the internal frame of the ultrasound machine caused by high temperature during use of the automatic welding tooling, and prevents the degradation of welding quality caused by misalignment of welding points.

[0022] In this embodiment, the horizontal arm 11 of the T-shaped pressure plate 1 is not longer than the axial length of the internal frame 5 of the ultrasound machine. Such a setting can ensure that the horizontal arm 11 that applies pressure to the internal frame 5 of the ultrasound machine does not affect the settings of other equipment and will not affect the operation of other equipment components. At the same time, the vertical arm 12 of the T-shaped pressure plate 1 is fixedly connected to the connecting piece 2.
