The main purpose of polishing steel grating is to remove impurities such as stains, rust, and oil stains on the surface, as well as to remove unevenness and burrs, thereby obtaining a smoother surface. For steel grating with special surface quality requirements, polishing treatment is also needed to obtain higher surface gloss and roughness requirements. In order to ensure the normal progress of polishing work, positioning tool is usually used to fix the steel grating, which is convenient for the normal work of polishing equipment.

The four sets of buffer clamps 5 are driven by the screw rod drive mechanism 6 to move along the sliding groove 4, so that the size of clamping can be adjusted in four directions. Therefore, the tool can be suitable for clamping and fixing steel gratings of any size within a certain range, and the tool has strong applicability.

Based on the above structure, the buffer clamp 5 which plays a clamping role has a buffering effect. When the clamping force is too large, the clamping plate 54 will be affected by the reaction force and will move backward to overcome the buffer spring 55, so that the clamping force will not be too large, thereby being able to buffer and protect the steel grating, preventing it from being worn or extruded and deformed. In addition, a guide rod 56 is slidably arranged on the vertical plate 52, one end of which is fixedly provided with a limiting piece, and the other end is fixedly connected with the clamping plate 54. The arrangement of the guide rod 56 can ensure that the clamping plate 54 will not deviate during movement, and the limiting piece arranged at the end thereof can prevent the sliding shaft 53 from sliding off the vertical plate 52.

[0029] In addition, the front end face of the clamping plate 54 is provided with a touch layer 57 made of rubber material, the back face of which is fixedly provided with a clamping strip 571, and the front end face of the clamping plate 54 is provided with a clamping groove corresponding to the clamping strip 571.

[0030] As shown in the figure, Figure 2 The lead screw driving mechanism 6 includes a set of longitudinal driving structure 61 and two sets of transverse driving structure 62. The longitudinal driving structure 61 is used to drive the corresponding two buffer clamps 5 to move close to or away from each other, and the transverse driving structure 62 is used to drive the corresponding buffer clamp 5 to move. The above structure can drive the corresponding buffer clamp 5 to move respectively, thereby completing the clamping and fixing work of steel gratings of different sizes. The longitudinal driving structure 61 and the transverse driving structure 62 have the same structure, both including a guide plate 601, in which a sliding table 602 is slidably arranged and is in transmission connection with the buffer clamp 5. The guide plate 601 is provided with a transmission lead screw 603 which is in threaded connection with the sliding table 602, and the end thereof is fixedly connected with an adjusting hand wheel 606. When the transmission lead screw 603 is twisted by the adjusting hand wheel 606, it will drive the sliding table 602 which is in threaded connection with it to slide along the guide plate 601, thereby realizing the movement of the buffer clamp 5.

[0031] In addition, a guide rib 604 is fixedly arranged on the inner wall of the guide plate 601, and guide grooves 605 matching the size of the guide rib 604 are formed on both sides of the sliding table 602. The above structure can prevent the sliding table 602 from sliding out of the guide plate 601 through the clamping action between the guide rib 604 and the guide groove 605, and this structure can also ensure the stability of the sliding of the sliding table 602.

[0032] As shown in the figure, Figure 3 -Figure 4 As shown in the figure, the upper end surface of the sliding table 602 is fixedly provided with a connecting sliding block 607, a plug-in groove 608 is formed in the connecting sliding block 607, the lower end surface of the sliding plate 51 is fixedly provided with a plug-in block 58 corresponding in size to the plug-in groove 608, and the connecting sliding block 607 and the sliding plate 51 are fixedly connected through the fixing bolt 7. The above structure can realize detachable connection between the whole buffer clamp 5 and the screw rod driving mechanism 6, and facilitate efficient performance of the later maintenance work.

[0033] As shown in the figure, Figure 5 As shown in the figure, the support connecting piece 2 comprises a support column 21, a limiting ring 22 is fixedly arranged at the bottom of the support column 21, and a threaded hole 23 is formed in the bottom end of the support column 21. Meanwhile, a counterbore 11 is formed in the lower end of the base 1, the support column 21 is plugged into the counterbore 11, and the counterbore 11 is provided with an anti-loosening bolt 24 threadedly connected with the threaded hole 23. The above structure can realize detachable connection between the support plate 3 and the base 1 through the fixed connection between the support column 21 and the base 1.

[0034] The use principle and use process of the utility model are as follows:

[0035] In the steel grating positioning tool, four groups of buffer clamps 5 are driven by the screw rod driving mechanism 6 to move along the sliding groove 4, so that the size of clamping can be adjusted in four directions, the tool can be suitable for clamping and fixing of steel gratings of any size within a certain range, and the tool has strong applicability. Specifically, the screw rod driving mechanism 6 comprises one group of longitudinal driving structure 61 and two groups of transverse driving structure 62. The longitudinal driving structure 61 is used to drive the corresponding two buffer clamps 5 to move synchronously close to or away from each other, and the transverse driving structure 62 is used to drive the corresponding buffer clamp 5 to move. The above structure can drive the corresponding buffer clamps 5 to move respectively, and then complete the clamping and fixing work of steel gratings of different sizes.

[0036] The longitudinal driving structure 61 and the transverse driving structure 62 are consistent in structure. When the transmission screw rod 603 is twisted by adjusting the hand wheel 606, the sliding table 602 threadedly connected with the transmission screw rod 603 will slide along the guide plate 601, and then the buffer clamp 5 is driven to move.

[0037] Meanwhile, the buffer clamp 5 which plays a clamping role has a buffering effect. When the clamping force applied is too large, the clamping plate 54 will be affected by the reaction force and move backward to overcome the buffer spring 55, so that the clamping force will not be too large, and then the steel grating can be protected by buffering to prevent it from being abraded or extruded and deformed.

[0038] Finally, it should be noted that: apparently, the above embodiments are merely examples for clearly illustrating the utility model, and are not limited to the implementation. For ordinary skilled in the art, on the basis of the above description, other different forms of changes or variations can be made. Here, it is not necessary and impossible to enumerate all the implementation. The obvious changes or variations derived therefrom are still within the scope of the utility model.
