Abstract

The utility model discloses a hydraulic torque converter connecting block with a prewelding groove. The connecting block comprises a connecting block body, and convex rings are arranged on the two sides of the bottom of the connecting block body. Due to the prewelding groove, the stress concentration in welding is lowered, the welding reliability is improved, and therefore the performance of hydraulic torque converter products is improved.

Description

A kind of MANUFACTURING CELL FOR LINK BLOCK OF TORQUE CONVERTER with pre-weld groove

Technical field

The utility model relates to a kind of fluid torque converter, specifically the contiguous block of fluid torque converter.

Background technique

For making power be passed to fluid torque converter by motor, generally adopt contiguous block that fluid torque converter is connected with engine flywheel.According to engine flywheel form difference, in single fluid torque converter, contiguous block number mostly is not 3 to 6 not etc.Contiguous block one end is fixed on fluid torque converter cap assembly, is circularly and evenly distributed, and means of fixation mostly is welding.The contiguous block the other end is threaded io the rich property dish of motor.So, the rich property dish of fluid torque converter and motor is rigidly connected.Contiguous block mainly works to transmit Engine torque.On present contiguous block, there is no pre-weld groove, can cause like this insufficient strength of prewelding, soldering reliability declines, thereby can not guarantee the product performance of fluid torque converter.

Model utility content

The purpose of this utility model is the deficiency existing for prior art, thereby provides a kind of prewelding intensity that increases to improve fluid torque converter performance.

For realizing above-mentioned model utility object, the technical solution adopted in the utility model is a kind of MANUFACTURING CELL FOR LINK BLOCK OF TORQUE CONVERTER with pre-weld groove, comprises contiguous block body, is provided with bulge loop in contiguous block body two bottom sides.

For increasing nugget size, improve weld strength, described bulge loop has two, symmetrical distribution centered by contiguous block center line.

Described bulge loop side is provided with pre-weld groove.

Described pre-weld groove has four, and every two one group, every group symmetrical centered by bulge loop.

The effect of pre-weld groove is exactly that liquid metal during to prewelding reserves molding space, and pre-postwelding contiguous block and converter cover are fitted tightly, and makes the location of contiguous block more accurate.

Beneficial effect: the utility model, owing to there being the existence of pre-weld groove, having reduced the stress of welding generation and concentrated, and has promoted soldering reliability, thereby has promoted fluid torque converter product performance.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation, and in figure, 4 is converter cover;

Fig. 2 is Fig. 1 partial enlarged drawing.

Embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, the present embodiment is implemented under take technical solutions of the utility model as prerequisite, should understand these embodiments and only be not used in restriction scope of the present utility model for the utility model is described.

As depicted in figs. 1 and 2, a kind of MANUFACTURING CELL FOR LINK BLOCK OF TORQUE CONVERTER with pre-weld groove, comprises contiguous block body 1, is provided with bulge loop 2 in contiguous block body 1 two bottom sides.Bulge loop 2 has two, symmetrical distribution centered by contiguous block 1 center line.Each side be provided with a pre-weld groove 3 at bulge loop 2, amount to four pre-weld grooves 3, every two one group, every group symmetrical centered by bulge loop 2.

Workpiece energising when projection welding, bulge loop heating, metal molten, compressive deformation, liquid metal, to two side flow, flows in pre-weld groove, and condensation afterwards forms nugget.

This contiguous block welded structure is reliable, and accurate positioning has reduced welding concentrated stress, has improved weld strength, thereby has promoted fluid torque converter product performance.
