Description

Technical Field

[0001] This utility model relates to the field of vortex shell manufacturing technology, and in particular to an auxiliary device for fixing the wax mold gate in vortex shell manufacturing. Background Technology

[0002] The turbine housing is an important component of the turbocharger structure. Due to its unique shape, the lost-wax casting process can be used to achieve mass production using a simple method.

[0003] When using the lost-wax casting process to produce volute shells, it is necessary to connect the prefabricated gate to the wax model. In mass production, a single gate will produce multiple volute shells. Currently, the connection between the gate and the wax model is mainly done manually. However, when fixing multiple wax models with a single gate, the lack of an effective support and control mechanism will cause deviations in the angle and position of the wax model adhesion, making the operation very inconvenient. Utility Model Content

[0004] This utility model addresses the deficiencies in the prior art by providing an auxiliary device for fixing the gate of a wax mold used in the manufacture of a vortex shell.

[0005] This utility model is achieved through the following technical solution:

[0006] An auxiliary device for fixing the gate of a wax model used in the manufacture of a volute includes an operating table, a hydraulic cylinder, a push-pull block, a guide seat, a sliding plate, an installation tube, a clamping mechanism, and a limiting mechanism. The hydraulic cylinder is installed on the inner top of the operating table. The push-pull block is fixedly installed at the telescopic end of the hydraulic cylinder. The guide seat is fixedly installed on the upper surface of the operating table. The sliding plate is clamped inside the guide seat. The installation tube is fixedly installed on the top of the sliding plate. The clamping mechanism is movably connected to the outer top of the installation tube. The limiting mechanism is clamped on the inner top of the installation tube. The clamping mechanism includes a collar, an installation plate, a guide seat, a pressure rod, and a locking block. The installation plate is fixedly installed on the outer side of the collar. The guide seat is fixedly installed on the top of the installation plate. The pressure rod is clamped on the top of the guide seat. The locking block is clamped on the upper surface of the installation plate.

[0007] In a preferred embodiment of the present invention, the limiting mechanism includes a cover plate, a locking strip, a locking post, a spring, a limiting plate, and a handle. The locking strip and the locking post are fixedly disposed at the bottom of the cover plate, the spring is sleeved on the outside of the locking post, the limiting plate is fixedly disposed at the bottom of the locking post, and the handle is fixedly disposed at the top of the cover plate.

[0008] The limiting mechanism is mainly used to facilitate the switching of work when fixing the wax model on both sides of the gate, and to limit and fix the clamping mechanism after switching to prevent it from rotating during the wax model fixing process.

[0009] In a preferred embodiment of this utility model, the collar is movably connected to the outer top of the mounting tube via a bearing, and the top of the collar is provided with a groove that mates with the retaining strip.

[0010] In a preferred embodiment of the present invention, the limiting plate is clamped on the inner side of the top of the mounting tube, a guide block is provided on the outer side of the limiting plate, a guide groove that cooperates with it is vertically opened on the inner side of the mounting tube, and a limiting ring is fixedly provided on the inner side of the top of the mounting tube.

[0011] The guide block on the outside of the limiting plate is locked in the guide groove inside the installation tube to limit the vertical movement of the locking post and prevent it from rotating, thereby ensuring that the locking strip at the bottom of the cover plate is always pressed in a fixed position, thus ensuring that the collar is locked in a fixed position.

[0012] In a preferred embodiment of this utility model, the pressure rod has sliding grooves at both ends that cooperate with the guide seat, and the mounting plate has a slot at the top that cooperates with the locking block.

[0013] The gate is effectively clamped and limited by the slots on the inside of the clamping block and the surface of the mounting plate, and is fixed by pressure applied by the pressure rod, thereby preventing the gate from being lifted up when connecting the gate to the wax mold at the bottom.

[0014] In a preferred embodiment of the present invention, one end of the push-pull block passes through the operating table and extends to the bottom inner side of the guide seat. One end of the push-pull block is fixed to the bottom outer side of the mounting tube. Guide grooves that cooperate with the push-pull block are provided on the upper surface of the operating table and the bottom of the guide seat.

[0015] The movement of the sliding plate of the mounting and clamping mechanism can be controlled by the retraction of the hydraulic cylinder, thereby always moving the processing position in front of the operator, thus facilitating the processing operation.

[0016] The beneficial effects of this utility model are:

[0017] This auxiliary device for fixing the wax mold gate in the manufacturing of volute shells effectively clamps and fixes the gate, thus facilitating the fixing of the wax mold at the bottom of the gate. Since multiple wax molds need to be fixed at the bottom of a single gate, the device can rotate and switch the mounting surface and switch the processing area, so that the area where the wax mold needs to be installed is always in front of the worker, which facilitates the wax mold installation and fixing work.

The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0024] like Figure 1-4 The illustrated auxiliary device for fixing the gate of a wax mold used in volute manufacturing includes an operating table 1, a hydraulic cylinder 2, a push-pull block 3, a guide seat 4, a sliding plate 5, an installation tube 6, a clamping mechanism 7, and a limiting mechanism 8. The hydraulic cylinder 2 is installed on the inner top of the operating table 1. The push-pull block 3 is fixedly installed at the telescopic end of the hydraulic cylinder 2. The guide seat 4 is fixedly installed on the upper surface of the operating table 1. The sliding plate 5 is clamped inside the guide seat 4. The installation tube 6 is fixedly installed on the top of the sliding plate 5. The clamping mechanism 7 is movably connected to the outer top of the installation tube 6. The limiting mechanism 8 is clamped on the inner top of the installation tube 6. The clamping mechanism 7 includes a collar 71, an installation plate 72, a guide seat 73, a pressure rod 74, and a locking block 75. The installation plate 72 is fixedly installed on the outer side of the collar 71. The guide seat 73 is fixedly installed on the top of the installation plate 72. The pressure rod 74 is clamped on the top of the guide seat 73. The locking block 75 is clamped on the upper surface of the installation plate 72.

[0025] Specifically, the limiting mechanism 8 includes a cover plate 81, a locking strip 82, a locking post 83, a spring 84, a limiting plate 85, and a handle 86. The locking strip 82 and the locking post 83 are fixedly installed at the bottom of the cover plate 81. The spring 84 is sleeved on the outside of the locking post 83. The limiting plate 85 is fixedly installed at the bottom of the locking post 83. The handle 86 is fixedly installed at the top of the cover plate 81. The collar 71 is movably connected to the top outer side of the mounting tube 6 through a bearing. The top of the collar 71 has a groove that mates with the locking strip 82. The limiting plate 85 is engaged with the top inner side of the mounting tube 6. A guide block is provided on the outer side of the limiting plate 85, and a guide groove is vertically opened on the inner side of the mounting tube 6 to cooperate with it. A limiting ring is fixedly installed on the inner side of the top of the mounting tube 6. The two ends of the pressure rod 74 are provided with sliding grooves to cooperate with the guide seat 73. The top of the mounting plate 72 is provided with a slot to cooperate with the card block 75. One end of the push-pull block 3 passes through the operating table 1 and extends to the bottom inner side of the guide card seat 4. One end of the push-pull block 3 is fixed to the bottom outer side of the mounting tube 6. The upper surface of the operating table 1 and the bottom of the guide card seat 4 are provided with guide grooves to cooperate with the push-pull block 3.

[0026] In this embodiment, the gate wax model is first clamped. After the inner groove of the clamping block 75 is clamped onto the surface of the gate wax model, the clamping block 75 and the gate wax model are clamped into the top slot of the mounting plate 72. Since the top of the gate wax model is a conical structure, the gate wax model can be suspended and fixed by the clamping block 75 and the groove on the surface of the mounting plate 72. Then, the pressure rod 74 is moved and, under the guidance of the guide seat 73, the pressure rod 74 is clamped onto the top of the gate wax model for pressing and fixing.

[0027] Further, the connection between the volute wax mold and the gate wax mold is carried out. As the hydraulic cylinder 2 retracts, the push-pull block 3 drives the sliding plate 5 to move, switching the processing area to facilitate the connection work. After the volute wax mold on one side is fixed, the handle 86 is lifted by hand. At this time, the limiting plate 85 will squeeze the spring 84, causing the locking strip 82 to separate from the top groove of the collar 71. The collar 71 can then be rotated to switch the processing surface at the top of the mounting tube 6. After releasing the handle 86, the cover plate 81 is pressed down under the action of the spring 84, causing the locking strip 82 to be re-locked into the top groove of the collar 71, achieving the limiting fixation. This achieves the limiting fixation of the clamping mechanism 7, so that the volute wax mold on the other side can be installed under the extension and retraction of the hydraulic cylinder 2.
