Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding equipment technology, and in particular to a grinding operation table. Background Technology
[0002] After the sprue is cut off, the casting needs to be ground and repaired by welding. The usual method is to place the casting on the ground or workbench, with the worker holding the casting with one hand and operating the grinding machine with the other. This method is labor-intensive, easily causing both hands to tire and become weak. Furthermore, the casting is not secured, making it easy for it to slip and roll, damaging the grinding wheel and potentially causing injury. Moreover, the dust generated by this method spreads and permeates the factory, posing a significant dust hazard to workers. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a grinding workbench. This workbench is semi-enclosed and connected to a dust removal system, which can greatly reduce dust pollution. In addition, the workbench is equipped with a magnetic suction device to fix the castings, thereby making it convenient for workers to operate the grinding machine with both hands and reducing labor intensity.

The front end of the operating space is open to facilitate worker operation, and the rear end is connected to the dust removal space. The top of the dust removal space is connected to the factory's dust removal system through a pipe. A dust collection trolley is provided at the lower end of the dust collection space. The switch of the magnetic device extends to the side of the grinding workbench cabinet and is connected to a control handle.
[0005] Preferably, the operating space includes a work area with the operating table at the front end and a dust collection channel for suction at the rear end, wherein the cross-section of the dust collection channel gradually decreases as it approaches the dust removal space.
[0006] Preferably, a plurality of vertically arranged flow equalization plates are provided at the connection between the rear end of the operating space and the dust removal space, and the flow equalization plates are inclined downwards and backwards.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the present invention.
[0017] like Figure 1 , 2 As shown, this embodiment of a grinding workbench is a multi-space cabinet, constructed from welded steel plates. For ease of explanation, [the following is used as an example]. Figure 2 Example, Figure 2 The left side is the front end in the text (the side where the worker stands during operations). Figure 2 The right side is the backend of the text.
[0018] This grinding workbench can be used for grinding casting sprues and for welding defects in castings. It includes an operating space 2, a dust collection space 3, and a dust removal space 4. The dust collection space 3 is located below the operating space 2 and is separated by a perforated steel plate, which serves as the workbench 1 and is used as the work surface for workers. The dust removal space 4 is located at the rear of the operating space 2 and primarily functions to extract dust-laden gases from the operating space 2 and other spaces. To enhance the extraction effect, the diameter of the dust collection channel at the rear of the operating space 2 gradually decreases.
[0019] Additionally, multiple vertically arranged flow equalization plates 7 are installed at the connection point between the rear end of the operating space 2 and the dust removal space 4. These flow equalization plates 7 are inclined downwards and backwards. When dust-laden airflow passes through this area, the flow equalization plates 7 cause the airflow to first descend and then ascend, entering the factory's dust removal system from the top of the dust removal space 4. Here, the flow equalization plates 7 guide and block the airflow, especially blocking dust particles in the airflow, thereby intercepting a portion of the dust in the airflow.
[0020] During operation, the worker places the casting on the operating table 1, then turns the handle of the magnetic device 5 to fix the casting in place using its magnetic attraction. This allows the worker to operate the grinding machine with both hands, reducing labor intensity and improving operational safety. The finer dust generated during grinding is carried by the airflow to the rear end of the operating space 2 and drawn into the dust removal space 4, and then into the factory's dust removal system. The coarser and heavier dust falls through the drain holes on the operating table 1 into the dust collection trolley 6.
[0021] To reduce the time that falling dust remains suspended in the air, the dust collection space 3 in this embodiment is equipped with a front slide 8 and a rear slide 9 that slope downwards towards the center from both ends. The front slide 8 and the rear slide 9 are in an inverted V-shape, and the dust collection trolley 6 is located below the bottom ends of the front slide 8 and the rear slide 9. In this way, most of the dust falling from the operating table 1 and from the dust extraction airflow first falls onto the front slide 8 and the rear slide 9, and then slides into the dust collection trolley 6.
[0022] In this embodiment, a chute 10 is also provided below the operating table 1. The chute 10 slopes downwards towards the front end of the dust collection space 3, and the top and rear end of the chute 10 are connected to the dust collection space 3. When dust from the operating table falls into the chute 10, the dust slides forward and downward along the chute 10 due to gravity. The top of the chute 10 is connected to the dust collection space 3, which in turn is connected to the dust removal space 4. Thus, the suction force present in the dust removal space 4 can also act on the top of the chute 10, thereby removing the finer and lighter dust particles from the falling dust. Moreover, this suction force is opposite to the direction in which most of the dust slides down, thus preventing dust from escaping from the front end of the dust collection space 3.
[0023] After the grinding operation is completed, the worker can turn the handle located on the side of the grinding table 180° to open the magnetic device 5, thereby removing or flipping the casting.
[0024] In this embodiment, to facilitate dust removal, the dust collection trolley 6 is pushed into the dust collection space 3 along the ground by casters, and the front end of the dust collection space 3 is provided with a double door to prevent dust from escaping.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, and for the convenience of describing the technical solution, the front, back, left, right, top, middle, and bottom orientations are based on the accompanying drawings and are not a limitation on the protection scope of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the essence and scope of the technical solution of this utility model.
