[0025] Embodiments

[0026] In order to solve the problem of low work efficiency and high labor intensity of workers in the prior art by manually polishing the surface of the steel plate, with reference to Figs. 1-3 The present application discloses an automatic steel plate granularity polishing equipment, which comprises a machine table 10, a reciprocating driving mechanism 20 and a polishing mechanism 30. Opposite sides of the machine table are provided with wire grooves 11. An upper portion of the machine table is provided with a positioning frame 12 for positioning and placing a steel plate.

[0027] The reciprocating driving mechanism comprises two linear driving assemblies 21 arranged in the wire grooves on the two sides, respectively, and a rack 22 connected to the two linear driving assemblies.

[0028] The polishing mechanism comprises a manual lifting adjusting assembly 30 arranged above the rack, a quick release block 32 connected to the manual lifting adjusting assembly below the rack, a polishing block 33 detachably fixed below the quick release block, and a polishing sandpaper 34 detachably arranged at the bottom of the polishing block.

[0029] Based on the above structure, the general principle of the present application is as follows: the operator first fixes the polishing sandpaper at the bottom of the polishing block and fixes the polishing block on the quick release block, then the operator places the steel plate in the positioning frame and drives the quick release block to descend by operating the manual lifting assembly to make the polishing sandpaper contact the surface of the steel plate. When the two linear driving assemblies drive the rack to move, the polishing sandpaper can repeatedly polish the steel plate.

[0030] In order to improve work efficiency, the number of positioning frames is two, and the polishing mechanism is provided with two and corresponds to the two positioning frames respectively. The depth of the positioning frame is less than the height of the steel plate, that is, during the reciprocating movement of the machine table driven by the reciprocating driving mechanism, the two polishing mechanisms will polish the steel plates in the two positioning frames respectively. By setting the depth of the positioning frame to be less than the height of the steel plate, the steel plate can be placed to leak out of the positioning frame, so that the polishing mechanism can polish the steel plate.

[0031] In some examples, the linear drive assembly of the present application is one of a motor lead screw module or a rodless cylinder, and the above two linear drive assembly structures are preferred structures of the present application. If a person skilled in the art has a better alternative solution that can realize the function of the present application, the selection can be adaptively made, and here it is not described in more detail.

[0032] In one specific embodiment, the manual lifting adjusting assembly of the present application includes a mounting plate 311 vertically arranged on one side of the table top of the rack and a lever clamp 312 fixed on the mounting plate and having its lever connected with the quick release block through the rack. When the operator operates the lever to lift or lower the lever, the polishing paper and the steel plate can be contacted or separated, which is relatively simple to operate and has strong practicability.

[0033] In a preferred embodiment, a T-shaped slot 321 is formed in the lower part of the quick release block, and a T-shaped plug-in block 331 is integrally arranged on the upper part of the polishing block and inserted into the T-shaped slot. In the specific implementation, the operator only needs to insert or pull out the T-shaped plug-in block from the T-shaped slot to realize the installation and disassembly of the polishing block.

[0034] In one embodiment, the polishing paper is fixed to the bottom of the polishing block by gluing, and when the polishing paper is replaced, it can be directly torn off from the bottom of the polishing block. This method is easy to operate and can reduce the labor time of the operator.

[0035] In order to accurately calculate the polishing frequency of the polishing paper on the steel plate, a counter 40 for detecting the movement frequency of the rack is arranged on the machine table. The counter of the present application counts once when the rack moves once, and it is emphasized that the present application also provides a PLC controller for controlling the device. The linear drive assembly and the counter of the present application are communicatively connected with the PLC controller. When the counter reaches the set value, the PLC controller can stop driving the linear drive assembly to work.
