AI Technical Summary
The positioning process of the trolley on the transfer car in existing casting equipment has problems of pauses and high costs, especially due to the increased cycle time and equipment costs caused by the use of cylinders.
A mobile positioning mechanism is adopted, which uses a buffer cylinder pusher, positioning frame, connecting frame, roller, guide shaft and guide frame. Through the design of the high, transition and low points of the track, the trolley is fixed on the transfer vehicle, eliminating the need for a cylinder positioning mechanism.
It achieves positioning of the trolley on the transfer vehicle without increasing the cycle time, while reducing equipment costs. It has a simple structure and is easy to control.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of supporting technology for casting equipment, and in particular relates to a mobile positioning mechanism. Background Technology
[0002] In the field of casting equipment, a common configuration consists of a central trolley conveyor section and two transfer cars at either end, each equipped with a push cylinder and a buffer cylinder. The movement of the trolley is achieved through the coordinated actions of the push and buffer cylinders. When the trolley reaches its designated position on the transfer car, a cylinder positioning device on the transfer car activates to fix the trolley in place before the transfer is completed. This configuration introduces pauses and waiting times, increasing the cycle time and adding cost due to the use of cylinders. Therefore, a device is needed that can achieve the positioning function without requiring additional cylinders. Summary of the Invention
[0003] To solve the above-mentioned technical problems, this utility model provides a mobile positioning mechanism to solve the problems of positioning and timing when the trolley moves onto the transfer vehicle.
[0004] The technical solution adopted by this utility model is a mobile positioning mechanism, including a hydraulic cylinder pusher, a positioning frame, a connecting frame, a connecting shaft, rollers, a guide shaft, a track, and a guide frame. The positioning frame and rollers are connected by the guide shaft, the positioning frame and the connecting frame are connected by the connecting shaft, the connecting frame is connected to the hydraulic cylinder pusher by bolts, the hydraulic cylinder pusher is connected to the buffer cylinder of the transfer vehicle, and the track and guide frame are installed on the transfer vehicle.
[0005] Furthermore, the surface of the track has three parts: high, transition, and low.
[0006] Furthermore, when the roller moves at the lower part of the track, the positioning bracket loosens and becomes ineffective.
[0007] Furthermore, as the rollers move to the transition point of the track, the positioning frame is tightened by the action of the guide frame and guide shaft, hooking the transfer car and fixing it in place.
[0008] The beneficial technical effects of this utility model are:
[0009] 1. This utility model utilizes a buffer cylinder to position the trolley on the transfer vehicle. Since the action of the buffer cylinder is within the cycle time, no cycle time is added, and the cylinder positioning mechanism is eliminated, thus reducing costs.
[0010] 2. The present invention solves the problem of trolley fixation by utilizing existing devices without adding cylinders. The structure is simple and easy to control. Attached Figure Description

[0014] The following detailed description, in conjunction with the accompanying drawings and preferred embodiments, describes the specific implementation methods, structures, features, and effects provided by this utility model.
[0015] A mobile positioning mechanism that saves cycle time and reduces costs includes a hydraulic cylinder pusher 1, a connecting shaft 2, a connecting frame 3, a positioning frame 4, rollers 5, a guide shaft 6, a guide frame 7, and a track 8. The positioning frame 4 and rollers 5 are connected by the guide shaft 6, the positioning frame 4 and connecting frame 3 are connected by the connecting shaft 2, the connecting frame 3 is connected to the hydraulic cylinder pusher 1 by bolts, and the hydraulic cylinder pusher 1 is connected to the buffer cylinder of the transfer vehicle. The track 8 and the guide frame 7 are installed on the transfer vehicle.
[0016] Furthermore, the upper surface of track 8 has three parts: a high point, a transition point, and a low point.
[0017] Furthermore, when roller 5 moves at a low position on track 8, positioning bracket 4 is released and becomes ineffective.
[0018] Furthermore, as the roller 5 moves to the transition area of the track 8, the guide frame 7 and guide shaft 6 ensure that the positioning frame 4 is tightened, hooks the trolley, and moves it; as the roller 5 moves to the high area of the track 8, the transfer car is fixed.
[0019] This utility model has significant advantages and beneficial effects compared with the prior art:
[0020] 1. This utility model utilizes a buffer cylinder to position the trolley on the transfer vehicle. Since the action of the buffer cylinder is within the cycle time, no cycle time is added, and the cylinder positioning mechanism is eliminated, thus reducing costs.
[0021] 2. The present invention solves the problem of trolley fixation by utilizing existing devices without adding cylinders. The structure is simple and easy to control.
[0022] The above description provides a detailed account of one embodiment of the present utility model. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the claims of the present utility model should fall within the patent coverage of the present utility model.
