Description

Technical Field

[0001] This invention relates to the technical field of precision casting, and in particular to an automatic bonding machine for impeller blade core wax molds. Background Technology

[0002] The impeller of the submersible electric pump is manufactured using investment casting, which includes processes such as wax pressing, mold repair, assembly, shell making, wax melting, firing, casting, and post-processing. This type of impeller uses a highly efficient closed structure. Due to the high manufacturing difficulty, the wax model cannot be injection molded in one step. The impeller wax model needs to be divided into two parts: a front cover plate and a rear cover plate with blades, which are wax-pressed separately. Before entering the assembly process, wax needs to be quickly applied manually using a fine brush to the connection points between each blade of the rear cover plate and the inner cavity of the front cover plate to bond them into a whole impeller model. It is difficult to guarantee the shape and size of the wax model, resulting in inconsistent product quality and low processing efficiency. In particular, traditional manual operation is not possible for impeller products with low flow channels and high twist blades. Summary of the Invention

The rotary cylinder 401 is located on one side of the X-axis linear module 201 and close to the impeller front cover base 203. The top of the output shaft of the rotary cylinder 401 is connected to a photosensitive heater bracket 402, and a photosensitive heater 403 is installed at the bottom of the photosensitive heater bracket 402.

[0035] The heating device 4 also includes a ball spline base 404 fixed on the upper surface of the working platform 1, a ball spline 405 mounted on the ball spline base 404, a support plate 406 mounted on the spline nut of the ball spline 405, a rotary cylinder 401 fixed on the support plate 406, a lead screw 407 mounted on the support plate 406 by a linear nut, the lead screw 407 connected to a linear stepper motor 408, and the linear stepper motor 408 fixed on the ball spline base 404.

[0036] A heat insulation plate 208 is provided on the X-axis moving plate 202, and the impeller front cover base 203 and the impeller rear cover base 204 are set on the heat insulation plate 208.

[0037] The front cover positioning fixture 205 has a lifting cylinder installed inside, and a support plate is provided on the top of the lifting cylinder.

[0038] The X-axis linear module 201 includes an X-axis ball screw mounting base, an X-axis ball screw is installed in the X-axis ball screw mounting base, the X-axis ball screw is connected to an X-axis motion drive motor, and the X-axis moving plate 202 is fixed on the nut of the X-axis ball screw.

[0039] The Y-axis linear module 301 includes a Y-axis ball screw mounting base, in which a Y-axis ball screw is installed. The Y-axis ball screw is connected to a Y-axis motion drive motor, and the Y-axis moving frame 302 is fixed on the nut of the Y-axis ball screw.

[0040] The Y-axis moving frame 302 is an L-shaped structure composed of a vertical plate and a horizontal plate. The vertical plate of the Y-axis moving frame 302 is fixed on the nut of the Y-axis ball screw, and the rear cover positioning fixture 303 is installed at the bottom of the horizontal plate of the Y-axis moving frame 302.

[0041] Two triangular reinforcing ribs are provided between the vertical plate and the horizontal plate of the Y-axis moving frame 302.

[0042] The specific steps of this invention are as follows:

[0043] First, when the impeller wax model is being bonded, select a suitable front cover positioning fixture 205 and install it on the impeller front cover base 203. Place the impeller front cover 5 on the front cover positioning fixture 205. Then, select a suitable rear cover positioning fixture 303 and install it on the bottom of the Y-axis moving frame 302. Use a vacuum suction cup to fix the wax model impeller rear cover 6 on the rear cover positioning fixture 303. Adjust the X-axis moving plate 202 on the X-axis linear module 201 and the Y-axis linear module. At the initial position of the Y-axis moving frame 302 on 301, the rotary cylinder 401 drives the photosensitive heater 403 to rotate above the impeller front cover 5, and under the action of the linear stepper motor 408 and the lead screw 407, it descends to the surface of the impeller front cover 5. The photosensitive heater 403 rapidly heats the surface of the impeller front cover 5. The wax model impeller rear cover 6 extends into the impeller rear cover top seat 207 under the drive of the Y-axis moving frame 302, and the heating plate 206 heats and melts the wax model. Figure 3 As shown;

[0044] In the second step, under the action of the linear stepper motor 408 and the lead screw 407, the rotary cylinder 401 rises and drives the photosensitive heater 403 to rotate away from the surface of the impeller front cover 5. The Y-axis moving frame 302 on the Y-axis linear module 301 moves upward away from the top seat 207 of the impeller rear cover. The position of the X-axis moving plate 202 on the X-axis linear module 201 is adjusted so that the impeller front cover 5 reaches below the Y-axis moving frame 302. The wax mold impeller rear cover 6 descends and contacts the surface of the impeller front cover 5 under the drive of the Y-axis moving frame 302 for bonding. Figure 4 As shown;

[0045] Thirdly, the vacuum suction device on the Y-axis moving frame 302 is turned off, causing the wax mold impeller rear cover 6 to separate from the rear cover positioning fixture 303. Figure 5 As shown, the lifting cylinder inside the front cover positioning fixture 205 then pushes out the bonded product.

[0046] This invention replaces the original manual waxing process by using mechanical hot melt bonding. No adhesive curing agent is needed during the wax mold bonding process, saving production costs; product positioning is accurate and efficient; and the mechanical bonding speed is fast, improving production capacity.

[0047] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
