Description

Technical Field

[0001] The utility model relates to the technical field of shaft head processing, and more specifically, to a cold storage for shaft head processing. Background Art

[0002] The shaft head is a part of mechanical equipment. In the field of industrial equipment, the shaft head also refers to the two ends of the shaft. The shaft is a mechanical part that supports rotating parts and rotates with them to transmit motion, torque or bending moment. It is generally in the shape of a metal round rod, and each section can have a different diameter. The parts that perform rotating motion in the machine are installed on the shaft.

[0003] The later stage of the processing of the shaft head involves the press-fitting of the pin. In this process, if the pin is directly aligned with the through hole on the shaft head for press-fitting, the pin may not be able to be tightly connected to the shaft head because the diameter of the through hole is not small enough. However, if the through hole is opened too small in advance, it will be difficult for the pin to be press-fitted into the through hole. Therefore, the principle of thermal expansion and contraction is usually used to put the shaft head into a cold storage before press-fitting, so that it drops to a certain temperature so that the through hole shrinks temporarily, and then press-fitting is performed. In this way, the pin will not be unable to be tightly connected to the shaft head because the through hole is not small enough, nor will it be difficult for the pin to be press-fitted into the through hole because the through hole is opened too small.

[0004] Existing cold storages usually include a refrigeration system including a compressor, a condenser, a pressure reducer, an evaporator, etc., however, since there is no placement rack suitable for the shaft heads, the shaft heads need to be placed in a storage box, and the storage box itself wastes the space of the cold storage, making it impossible to maximize the use of the cold storage to refrigerate as many shaft heads as possible, and when the storage boxes are stacked up to increase the available space, the shaft heads located at the lower level may not be cooled well. Utility Model Content

[0005] The utility model aims to provide a cold storage for shaft head processing, which solves the problem that the existing cold storage cannot efficiently place enough shaft heads to refrigerate them at the same time, resulting in delay in the subsequent pressing process of the shaft heads.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a cold storage for shaft head processing, including a box body, a plurality of rotating columns are rotatably arranged on the side wall of the box body, a support rod for hanging the shaft head is fixedly connected to one side of each rotating column, and the end of the support rod away from the rotating column is higher; a positioning assembly, which has a total of several groups, each group of positioning assemblies is respectively fixedly connected to each rotating column, and is used to rotate or fix the rotating column; a limiting assembly, which has a total of several groups, each group of limiting assemblies is respectively arranged at one end of each support rod away from the rotating column, and is used to prevent the shaft head from slipping; wherein a refrigeration mechanism for refrigeration is arranged in the box body.

[0007] The working principle of this technical solution is as follows: when in use, first remove the limiting assembly, hang the shaft head on several support rods and then reinstall the limiting assembly, then turn on the refrigeration mechanism for refrigeration. After the refrigeration is completed, control the positioning assembly to rotate the rotating column and the support rod so that the end of the support rod away from the rotating column is lower. At this time, the limiting assembly can be removed, and the shaft head will automatically slide down along the straight support rod under the action of gravity, and the staff only needs to use a box to receive it.

[0008] In summary, the utility model has the following beneficial effects:

[0009] Compared with the prior art, the utility model provides a cold storage for shaft head processing, in which a limiting component, a support rod, a positioning component and a rotating column cooperate with each other to maximize the utilization of the cold storage space while ensuring the refrigeration effect of each shaft head.

[0010] Furthermore, each group of the positioning components includes a connecting rod and a mounting block, wherein the mounting block is fixedly arranged on the side wall of the box body, one end of the connecting rod is fixedly connected to the rotating column, and the other end passes through the box body and the mounting block in sequence, and is fixedly connected to the control block, and four grooves are axially equidistantly opened on one side of the mounting block close to the control block, and a positioning piece for positioning the rotating column is arranged in each groove, and a handle is installed on each of the control blocks.

[0011] Furthermore, each of the positioning members includes a ball plunger installed in the groove, and the control block is provided with a limiting groove that cooperates with the ball plunger.

[0012] Furthermore, each group of the limiting components includes a "T-shaped" pull block inserted into the end of the support rod, a chamber is opened inside the support rod, and a mounting groove connected to the chamber is opened on the top of the support rod, wherein a slider is provided on the fixed sleeve of the pull block for sliding connection with the inner wall of the chamber, a spring is provided between the slider and the side wall of the chamber, a baffle is slidably arranged in the mounting groove, and a fixing groove cooperating with the pull block is opened on one side of the baffle, and one end of the pull block passes through one side of the chamber and extends into the fixing groove to lock the baffle.
