Description

Technical Field

[0001] The utility model relates to the technical field of pump housing processing tooling, and particularly relates to a drilling and countersinking tooling for pump housing processing. Background Art

[0002] Countersinking, a metal processing method, refers to processing cylindrical counterbores, conical counterbores, boss end faces, etc. on the already processed holes. The tool used for countersinking is called a countersink drill, which is generally made of high-speed steel.

[0003] When processing a pump housing, it is necessary to perform countersinking on it to improve the processing accuracy and facilitate the subsequent installation work; when countersinking the pump housing, it is necessary to fix the pump housing first. Most of the existing fixing methods use bolts and clamping blocks for clamping and limiting. Although this method can fix and limit the pump housing, the use of multiple groups of bolts makes it time-consuming and laborious to disassemble and install the pump housing, resulting in low processing efficiency.

[0004] Therefore, this application provides a drilling and countersinking tooling for pump housing processing to meet the requirements. Content of the Utility Model

[0005] The purpose of this application is to provide a drilling and countersinking tooling for pump housing processing, aiming to solve the problem that the existing pump housing is not convenient for installation and disassembly during drilling and countersinking processing, resulting in low processing efficiency.

[0006] To achieve the above purpose, this application provides the following technical solution: A drilling and countersinking tooling for pump housing processing, including a processing table, and an end support assembly for supporting the end of the pump housing to be processed is provided on the processing table, and the end support assembly limits the movement of the pump housing in the horizontal axis direction;

[0007] A support seat for limiting the pump housing in the longitudinal axis direction is further provided on the processing table; a pressing assembly for limiting the pump housing in the vertical axis direction is further provided on the processing table. By setting the pressing assembly on the workbench, the pump housing can be pressed and limited. Under the action of the rotating cylinder, while driving the pressing block to rotate, one side of the pressing plate is pulled downward, so that the pressing plate presses and limits the pump housing, and the pump housing can be countersunk. At the same time, under the drive of the rotating cylinder, it is convenient to limit and release the limit of the pump housing, improving the processing efficiency of the pump housing.

[0008] Preferably, the end support assembly includes baffles, there are two groups of the baffles, the baffles are L-shaped plates, including a horizontal plate and a vertical plate. The horizontal plate is connected to the processing table through bolts, the vertical plate is in contact with the pump housing, and the distance between the two vertical plates is equal to the length dimension of the pump housing.

[0009] Preferably, there are two sets of the support seats, and chamfers are provided at the opposite ends of the support seats and the pump housing, and they are in contact with the side wall of the pump housing. Through the action of the end support assembly and the support seats, the pump housing can be fixed and limited on the horizontal plane, and the end support assembly and the support seats are fixed to the processing table by bolts. When processing pump housings of the same batch, the pump housing can be directly placed on the support seats, and the end support assembly can directly limit the pump housing, avoiding the disassembly and installation of bolts.

[0010] Preferably, the pressing assembly includes a mounting plate and a pressing plate. The mounting plate is arranged on the processing table and is arranged along the transverse axis direction of the pump housing. One side of the pressing plate is hinged to the top of the mounting plate through a hinge, and a limiting mechanism is arranged between the other side of the pressing plate and the processing table.

[0011] Preferably, the limiting mechanism includes a rotating cylinder and a pressing block. The rotating cylinder is installed on the processing table, and the pressing block is connected to the telescopic end of the rotating cylinder. A through hole adapted to the pressing block is provided on the pressing plate. Driven by the rotating cylinder, the pressing block moves downward to press the pressing plate, and at the same time, the pressing block rotates 90 degrees.

[0012] In summary, the technical effects and advantages of the present utility model are as follows:

[0013] In the present utility model, through the action of the end support assembly and the support seats, the pump housing can be fixed and limited on the horizontal plane, and the end support assembly and the support seats are fixed to the processing table by bolts. When processing pump housings of the same batch, the pump housing can be directly placed on the support seats, and the end support assembly can directly limit the pump housing, avoiding the disassembly and installation of bolts; a pressing assembly is arranged on the workbench to press and limit the pump housing. Under the action of the rotating cylinder, while driving the pressing block to rotate, one side of the pressing plate is pulled downward, so that the pressing plate presses and limits the pump housing, and counterboring processing can be carried out on the pump housing. At the same time, driven by the rotating cylinder, it is convenient to limit and release the limit of the pump housing, improving the processing efficiency of the pump housing.
