Description

Technical Field

[0001] This utility model relates to the field of workpiece clamping technology, specifically to an auxiliary clamping mechanism for chromium plating production. Background Technology

[0002] Chromium plating is a surface treatment process that improves the performance and appearance of metals by plating a layer of chromium onto the metal surface. The main purposes of chromium plating include improving the corrosion resistance, hardness, and wear resistance of metals, as well as beautifying the metal surface. Chromium plating is usually carried out using electroplating, in which the metal workpiece is used as the cathode and chromium is used as the anode. The current in the electrolyte causes chromium ions to be deposited on the metal surface to form a chromium layer.

[0003] CN219239808U discloses a clamping fixture for chrome plating of metal parts in food machinery. The fixture features a threaded rod inside a limiting slide groove, with a movable clamping plate on the outer surface of the threaded rod, the top of which is positioned inside the limiting slide groove. The fixture includes an electric telescopic rod that can adjust the position of a movable plate along a lifting slide groove, allowing the component to enter the chrome plating bath for chrome plating. A movable base is located on the bottom surface of the movable plate, allowing for position adjustment along the sliding groove and the limiting groove. A movable frame on the bottom surface of the movable base is detachably connected to the base via fastening bolts, facilitating easy replacement of the frame. The movable clamping plate on the bottom surface of the frame can be displaced under the action of the threaded rod, enabling the device to secure components of different sizes.

[0004] The aforementioned patent addresses the shortcomings of existing clamping fixtures, which make it inconvenient to adjust the spacing between clamping fixtures according to the size of the parts, thus affecting the clamping and fixing of the parts.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1, please refer to Figures 1 to 5This embodiment of a chrome plating production auxiliary clamping mechanism includes an auxiliary mounting plate 1 and a connecting rod 2. Two hydraulic telescopic rods 3 are fixedly mounted on the lower surface of the auxiliary mounting plate 1. An auxiliary connecting plate 4 is fixedly mounted on the bottom of the hydraulic telescopic rods 3. A connecting assembly mechanism is provided between the connecting rod 2 and the auxiliary connecting plate 4. The connecting assembly mechanism includes a rectangular cavity 5 opened inside the connecting rod 2. A top spring 6 is fixedly mounted inside the rectangular cavity 5. A pressing rod 7 that extends through to the top surface of the connecting rod 2 is fixedly mounted on the top of the top spring 6. A strip hole 15 communicating with the inner cavity of the rectangular cavity 5 is opened on the surface of the connecting rod 2. A T-shaped lever 16 located in the strip hole 15 and extending to the outer surface of the connecting rod 2 is fixedly mounted on the surface of the pressing rod 7. The T-shaped lever 16 facilitates the movement of the pressing rod 7 within the rectangular cavity 5. The top surface has two mounting slots 8, and a connecting plate 9 is rotatably mounted inside the mounting slots 8. A compression compensation block 10 is fixedly mounted on the opposite side surface of each of the two connecting plates 9. The bottom surface of the compression compensation block 10 is beveled, and the top of the compression rod 7 is conical to facilitate contact between the compression rod 7 and the compression compensation block 10, pressing the two connecting plates 9 to both sides. A locking block 11 is fixedly mounted on the opposite side surface of each of the two connecting plates 9. The auxiliary connecting plate 4 has multiple grooves 12 connected to its lower surface. A locking slot 13 is formed on the opposite side surface of each groove 12, and the locking block 11 fits into the locking slot 13. The side surface of the locking block 11 away from the connecting plate 9 is beveled to facilitate the locking block 11 engaging with the locking slot 13. A U-shaped frame 14 is fixedly mounted on the bottom of the connecting rod 2.

[0023] The U-shaped frame 14 is provided with a workpiece clamping assembly. The workpiece clamping assembly includes two electric telescopic rods 17 fixedly installed on opposite sides of the inner surface of the U-shaped frame 14. An arc-shaped clamping plate 18 is fixedly installed at one end of the electric telescopic rod 17. A rubber round strip 19 is fixedly installed on the inner surface of the arc-shaped clamping plate 18. Two clamping plates 20 are fixedly installed on the outer surface of the arc-shaped clamping plate 18. There are multiple rubber round strips 19, which are evenly distributed on the inner surface of the arc-shaped clamping plate 18.

[0024] The working principle of the above embodiments is as follows:

[0025] In use, the auxiliary mounting plate 1 is fixedly installed in the designated position. The hydraulic telescopic rod 3 can drive the auxiliary connecting plate 4 and the connecting rod 2 to rise and fall, thereby realizing the lifting and lowering of the workpiece. When connecting the connecting rod 2 and the auxiliary connecting plate 4, the T-shaped lever 16 retracts the extrusion rod 7 into the rectangular cavity 5, and the top spring 6 is compressed. At this time, the extrusion rod 7 separates from the extrusion compensation block 10, which allows the two connecting plates 9 to move closer to the middle. The connecting plate 9 and the locking block 11 are placed in the groove 12. At this time, the locking block 11 is inclined in the groove 12 and corresponds to the locking slot 13. The T-shaped lever 16 is released, and the top spring 6 pushes the extrusion rod 7 out of the rectangular cavity 5. The extrusion rod 7 squeezes the extrusion compensation block 10 to both sides, thereby causing the connecting plate 9 and the locking block 11 to move to both sides until the locking block 11 is locked into the locking slot 13, thus completing the connection between the connecting rod 2 and the auxiliary connecting plate 4. During use, the connecting rod 2 can be adjusted to other grooves 12 according to the size of the workpiece.

[0026] When clamping a workpiece, the workpiece is placed between two arc-shaped clamping plates 18. The arc-shaped clamping plates 18 can be moved closer to the workpiece by the electric telescopic rod 17. The arc-shaped clamping plates 18 and the rubber round strip 19 can clamp cylindrical workpieces, and the clamping plate 20 can clamp rectangular workpieces.

[0027] In Embodiment 2, based on Embodiment 1, a circular hole communicating with the rectangular cavity 5 is provided on the top surface of the connecting rod 2, and the extrusion rod 7 is located inside the circular hole, so that the extrusion rod 7 can extend to the top outer surface of the connecting rod 2 through the circular hole.
