Description

Technical Field

[0001] This utility model relates to the field of metal block surface processing technology, and in particular to a clamping assembly for metal surface treatment. Background Technology

[0002] After production, metal blocks require surface finishing processes such as polishing. During this process, the metal block must first be fixed in place, and the stability of this fixation affects the quality of the surface treatment. For example, if the metal block shifts position during surface treatment, some surfaces may remain unpolished while others are over-polished, thus impacting the overall quality of the metal block.

[0003] Most existing metal block clamping assemblies use two clamping plates to hold the metal block on two opposite sides. This fixing method can ensure that the metal block remains stable in the vertical or horizontal direction, but the stability in the other direction cannot be guaranteed. Utility Model Content

[0004] This invention provides a clamping assembly for metal surface treatment, which solves the technical problem that existing clamping assemblies cannot fix metal blocks at all angles.

[0005] To achieve this technical objective, the present invention adopts the following solution: a clamping assembly for metal surface treatment, comprising a worktable, a positioning mechanism, a tray, and a floating fixing mechanism; Two positioning mechanisms are symmetrically fixed on the worktable. The two positioning mechanisms are not parallel and are used to fix two adjacent sides of the metal block. The tray is fixed on the workbench and is positioned between two positioning mechanisms to hold metal blocks; The floating fixing mechanism is fixed at one end of the worktable away from the positioning mechanism and is used to fix the other two sides of the metal block.

[0006] Furthermore, the positioning mechanism includes a fixed frame and a first positioning roller; The mounting bracket is fixed to the workbench; Two first positioning rollers are arranged laterally and rotatably on the top surface of the fixed frame, and the two first positioning rollers abut against the same side of the fixed metal block.

[0007] Furthermore, the surface of the pallet is coated with a graphite layer.

[0008] Furthermore, the floating fixing mechanism includes an electric push rod, a first slide rail, a first slider, a second slide rail, a second slider, a second positioning roller, and a return unit; The electric actuator is fixed to the worktable; The first slide rail is fixed between the electric push rod and the support plate, and the first slide rail is arranged in the same direction as the electric push rod. The first slider is slidably mounted on the first slide rail, and the first slider is fixedly connected to the movable end of the electric actuator. The second slide rail is fixed to the top of the first slide rail, and the second slide rail is set perpendicular to the first slide rail; The second slider is slidably mounted on the second slide rail; Two second positioning rollers are rotatably mounted on the top surface of the second slider near the metal block. The two second positioning rollers are spaced apart and abut against two adjacent sides of the metal block, respectively. Two return-to-center units are symmetrically arranged on both sides of the second slider, and the two return-to-center units abut against the two opposite sides of the second slider, respectively.

[0009] Furthermore, the return unit includes a vertical plate, a plug rod, a pressure block, and a spring; The upright plate is fixed to the workbench; The insertion rod is inserted into the upright plate in a sliding manner but cannot rotate on its own; The pressure block is fixed to the end of the insertion rod, and the pressure block abuts against the second slider; The spring is sleeved on the outside of the insert rod, and the two ends of the spring abut against the upright plate and the pressure block, respectively.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The present invention discloses a clamping assembly for metal surface treatment, which is provided with two positioning mechanisms. These two positioning mechanisms are used to fix two adjacent sides of the metal block, thereby ensuring the stability of one corner of the metal block. Then, the other two sides of the metal block are fixed by a floating fixing mechanism to achieve the overall fixation of the metal block. The bottom of the metal block is fixed by setting a support plate, so that its top surface is exposed to the outside, which is convenient for surface treatment.

[0011] Due to the movable nature of the floating fixing mechanism, the clamping assembly can be matched with metal blocks of different sizes, thus improving the applicability of the clamping assembly. Attached Figure Description

[0014] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.

[0015] like Figures 1-2 As shown, this utility model discloses a clamping assembly for metal surface treatment, including a worktable 1, a positioning mechanism 2, a tray 3, and a floating fixing mechanism 4. Two positioning mechanisms 2 are symmetrically fixed on the workbench 1. The two positioning mechanisms 2 are not parallel and are used to fix two adjacent sides of the metal block 5. The tray 3 is fixed on the workbench 1 and is positioned between the two positioning mechanisms 2 for holding the metal block 5. The floating fixing mechanism 4 is fixed on the worktable 1 at one end away from the positioning mechanism 2, and is used to fix the other two sides of the metal block 5.

[0016] Furthermore, the positioning mechanism 2 includes a fixed frame 21 and a first positioning roller 22; The mounting bracket 21 is fixed on the workbench 1; Two first positioning rollers 22 are laterally and rotatably spaced on the top surface of the fixed frame 21, and the two first positioning rollers 22 abut against the same side of the fixed metal block 5.

[0017] Furthermore, the surface of tray 3 is coated with a graphite layer.

[0018] Furthermore, the floating fixing mechanism 4 includes an electric push rod 41, a first slide rail 42, a first slider 43, a second slide rail 44, a second slider 45, a second positioning roller 46, and a return unit 47; The electric actuator 41 is fixed on the worktable 1; The first slide rail 42 is fixed between the electric push rod 41 and the support plate 3, and the first slide rail 42 is arranged in the same direction as the electric push rod 41. The first slider 43 is slidably mounted on the first slide rail 42, and the first slider 43 is fixedly connected to the movable end of the electric push rod 41. The second slide rail 44 is fixed on the top of the first slider 43, and the second slide rail 44 is set perpendicular to the first slide rail 42. The second slider 45 is slidably mounted on the second slide rail 44; Two second positioning rollers 46 are rotatably disposed on the top surface of the second slider 45 near the metal block 5. The two second positioning rollers 46 are spaced apart and abut against the two adjacent sides of the metal block 5 respectively. Two return-to-center units 47 are symmetrically arranged on both sides of the second slider 45, and the two return-to-center units 47 respectively abut against the two opposite sides of the second slider 45.

[0019] Furthermore, the return unit 47 includes a vertical plate 471, a plug rod 472, a pressure block 473, and a spring 474; The upright plate 471 is fixed on the workbench 1; The insertion rod 472 is slidably and non-rotatable inserted into the upright plate 471. As a way to limit the rotation of the insertion rod 472, a limiting strip extending along its length can be integrally formed on the outer wall of the insertion rod 472, and a limiting groove corresponding to the limiting strip can be opened on the upright plate 471. The limiting strip is slidably locked in the limiting groove.

[0020] The pressure block 473 is fixed to the end of the insertion rod 472, and the pressure block 473 abuts against the second slider 45; Spring 474 is sleeved on the outside of insert rod 472, and the two ends of spring 474 abut against vertical plate 471 and pressure block 473 respectively.

[0021] In use, the metal block 5 is placed on the support plate 3, with one edge of the metal block 5 positioned between the two positioning mechanisms 2. Then, the electric push rod 41 is activated, causing the first slider 43 to move closer to the metal block 5 until the second positioning roller 46 contacts the metal block 5. The electric push rod 41 continues to move, and the second positioning roller 46 presses against the metal block 5, causing the metal block 5 to move until all four sides of the metal block 5 are pressed tightly by the first positioning roller 22 and the second positioning roller 46, respectively. At this point, the metal block 5 is completely fixed.

[0022] During the process of pressing the metal block 5, the second positioning roller 46 can slide on the second slide rail 44 along with the second slider 45, thereby floating the second positioning roller 46 and positioning the two second positioning rollers 46 in the appropriate position so that they can eventually press the two sides of the metal block 5.

[0023] After the surface treatment is completed, the electric push rod 41 is reset, the second slider 45 is reset under the restoring force of the spring 474, and the second positioning roller 46 is reset accordingly.

[0024] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
