AI Technical Summary
The existing water sprayer has only one water inlet, which makes it impossible to control the heating deformation of the parts on the upper, middle and lower fairways respectively, resulting in taper in the fairway size after cooling.
A new type of water sprayer is designed, adopting three-layer structures of upper, middle and lower, and independent high-pressure water inlets and water spray positions are set at the upper, middle and lower positions respectively. The cooling speed is controlled separately by controlling the magnitude of high-pressure water flow.
Independent cooling control of the upper, middle and lower parts of the fairway of the part is achieved, ensuring that the fairway size is within the required range and avoiding dimensional deformation after cooling.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of drive shaft processing, in particular to a novel water sprinkler. Background Art
[0002] During the processing of automobile drive shaft, induction hardening process is required. When induction hardening is performed on parts (bell housing), Figure 1 As shown, a chuck (1') is first moved up and down by three jaws to clamp the part (2'), and the part's ball path is induction heated on the inductor (3'). Simultaneously with the induction heating, a water sprinkler (4') injects high-pressure water through the water inlet (5'), and then sprays the outer wall of the part to cool it. However, because the existing water sprinkler has only one water inlet and a single water flow rate, it cannot separately control the cooling of the upper, middle, and lower parts of the part's ball path due to heating deformation, resulting in a tapered ball path size after cooling. Utility Model Content
[0003] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a new type of water sprinkler, which can realize the spraying of water at different flow rates on the upper, middle and lower positions of the outer wall of the ballway of the part, thereby controlling the heating deformation of the upper, middle and lower parts of the ballway respectively, and finally controlling the taper of the ballway size within the required range.
[0004] The purpose of the present utility model is achieved through the following technical solutions: this new type of water sprinkler includes an upper structure, a middle structure and a lower structure stacked in sequence from top to bottom, all of which are annular, and the inner holes of the three are interconnected, and are used to be placed in a bell-shaped shell, and a heating sensor extends into the bell-shaped shell to perform induction quenching on the ball path of the bell-shaped shell; an upper water inlet is provided on the outer wall of the upper structure, and an upper water spraying position is correspondingly provided on the inner wall of the upper structure, which is used to spray water to cool the upper outer wall of the bell-shaped shell; a middle water inlet is provided on the outer wall of the middle structure, and a middle water spraying position is correspondingly provided on the inner wall of the middle structure, which is used to spray water to cool the middle outer wall of the bell-shaped shell; a lower water inlet is provided on the outer wall of the lower structure, and a lower water spraying position is correspondingly provided on the inner wall of the lower structure, which is used to spray water to cool the lower outer wall of the bell-shaped shell.
[0005] As a further technical solution, the bell-shaped housing is clamped by a chuck and placed in the inner hole.
[0006] As a further technical solution, the upper water inlet, the middle water inlet and the lower water inlet are all located at the same position on the outer wall of the bell-shaped housing.
[0007] As a further technical solution, the heating sensor is fixed on the sensor base.
[0008] The beneficial effects of the utility model are:
[0009] 1. The water sprayer adopts a three-layer structure of upper, middle and lower layers. The required high-pressure water is injected through the upper, middle and lower water inlets respectively, and the flow rate of the high-pressure water is controlled respectively, and then the outer wall of the part is sprayed with water for cooling;
[0010] 2. Due to the use of three independent high-pressure water inlets, the flow rate of water sprayed at the upper, middle and lower spray positions can be controlled, so the cooling speed of the spray positions can be controlled separately, and ultimately the upper, middle and lower dimensional deformation of the part ball track can be controlled.

DETAILED DESCRIPTION
[0019] The following is a detailed introduction to the present invention with reference to the accompanying drawings:
[0020] Example: As shown in the attached Figures 2 to 6 As shown, this new type of sprinkler includes a bell-shaped housing 1, a ball channel 11, an upper structure 2, an upper water inlet 21, an upper water spraying position 22, a middle structure 3, a middle water inlet 31, a middle water spraying position 32, a lower structure 4, a lower water inlet 41, a lower water spraying position 42, a chuck 5, a heating sensor 6 and a sensor base 7.
[0021] Reference Attachment Figure 4The sprinkler includes an upper structure 2, a middle structure 3 and a lower structure 4 stacked in sequence from top to bottom. The three are all ring-shaped, and the inner holes of the three are interconnected. Figure 6 As shown, the bell-shaped housing 1 is clamped by the chuck 5 and placed in the inner hole. During induction heating, the heating sensor 6 is extended into the bell-shaped housing 1 to perform induction hardening on the ball channel 11 of the bell-shaped housing 1. Figure 3 As shown, 6 ball lanes 11 are evenly opened on the inner wall of the bell housing 1. Preferably, as Figure 6 As shown, the heating inductor 6 is fixed on the inductor base 7.
[0022] Furthermore, an upper water inlet 21 is opened on the outer wall of the upper structure 2, and an upper water spray position 22 (composed of multiple water spray holes) is opened on the inner wall of the upper structure 2, which can spray water to cool the upper outer wall of the bell-shaped shell 1. A middle water inlet 31 is opened on the outer wall of the middle structure 3, and a middle water spray position 32 (composed of multiple water spray holes) is opened on the inner wall of the middle structure 3, which can spray water to cool the middle outer wall of the bell-shaped shell 1. A lower water inlet 41 is opened on the outer wall of the lower structure 4, and a lower water spray position 42 (composed of multiple water spray holes) is opened on the inner wall of the lower structure 4, which can spray water to cool the lower outer wall of the bell-shaped shell 1.
[0023] like Figure 5 As shown, the upper water inlet 21, the middle water inlet 31 and the lower water inlet 41 are all located at the same position on the outer wall of the bell-shaped housing 1, which is convenient for connecting an external high-pressure water pipe and reduces confusion in pipe wiring.
[0024] The working process of the present invention is as follows: when the bell-shaped housing 1 is subjected to induction hardening, the bell-shaped housing 1 is first clamped by moving the chuck 5 up and down, and the heating inductor 6 is inserted into the bell-shaped housing 1, so that the ball channel 11 of the bell-shaped housing 1 is inductively heated on the heating inductor 6. Simultaneously with the induction heating, the sprinkler injects the required high-pressure water through the upper, middle, and lower water inlets, respectively, and controls the flow rate of the high-pressure water, and then sprays water to cool the outer wall of the bell-shaped housing 1. Due to the use of three independent high-pressure water inlets, the flow rate of the water sprayed at the upper, middle, and lower water spraying positions can be controlled (as shown by the water outlet arrows in the figure), thereby controlling the cooling rate of the water spraying positions, and ultimately controlling the deformation of the upper, middle, and lower dimensions of the ball channel 11 of the bell-shaped housing 1.
[0025] It is understandable that for those skilled in the art, any equivalent replacement or change of the technical solution and the concept of the utility model should fall within the scope of protection of the claims attached to the utility model.
