Problems solved by technology

Therefore, splitting is easy to occur at the top of the double-channel partition wall, and it is easy to over-grind the top of the partition wall during the splitting and grinding process of the top of the partition wall
Because the customer has strict requirements on the top of the partition wall, the grinding of the top of the partition wall has brought great difficulties to the production

Embodiment Construction

[0013] The present invention will be further elaborated below according to the drawings.

[0014] Such as figure 1 As shown, the grinding head for grinding the partition wall of the double-channel turbine casing includes a grinding block 2 and a handle 1, and the handle 1 is fixed in the middle of the grinding block 2, and the grinding block 2 is a columnar block, and the grinding block 2 Arc grooves 3 are respectively arranged on both sides.

[0015] The thickness of the grinding block 2 is set to 5mm.

[0016] Described arc groove 3 is located at the middle part of polishing block 2 two ends, and the arc dimension of arc groove 3 is the semicircle arc that radius is 3mm, and the upper and lower ends of arc groove 3 symmetrically leave certain margin.

[0017] Further, the bottom of the handle 1 is provided with a threaded structure for connecting the pneumatic tool 5 .

[0018] Working process of the present invention is:

[0019] The first step: install the grinding hea...

Abstract

The invention relates to a sand core grinding tool for producing turbine shells, in particular to a grinding head for grinding a partition wall of a double-flow-channel turbine shell. The grinding head comprises a grinding block and a handle, the handle is fixed in the middle of the grinding block and is integrally arranged to be in a T shape, and arc-shaped grooves are respectively formed in thetwo ends of the grinding block. According to the design, the working surface of the grinding head is changed from a straight surface to an arc shape equivalent to a grinding position, and the arc shape can wrap and clamp a fixed position of a slit during grinding, so that the operation difficulty of grinding work at the position can be effectively reduced, the production efficiency of the grindingwork is improved, and the final quality of a product is guaranteed.

Description

technical field [0001] The invention relates to a sand core grinding tool used in the production of a turbine casing, in particular to a grinding head for grinding a partition wall of a double-channel turbine casing. [0002] technical background [0003] As the country's restrictions on fuel consumption and emissions become more and more stringent, the trend of miniaturization of gasoline engines is becoming more and more obvious. After miniaturization, the requirements for low-end performance and transient performance are stricter. Compared with the single-channel supercharger, it can significantly improve the low-end performance of the engine and improve the transient performance of the engine. Therefore, dual-channel superchargers are more and more widely used, and the types and quantities of double-channel turbine casings are also significantly increased. Because of the structural problems of the double runners, the two runners can only be made separately when designing...
