Description

Technical Field

[0001] This utility model belongs to the field of metal product processing technology, and in particular relates to a metal product clamping device. Background Technology

[0002] In the metal product processing and assembly process, precise and stable clamping of workpieces is a key link to ensure processing quality and improve production efficiency. It directly affects the accuracy and safety of subsequent cutting, welding and other processes. Especially in automated production lines, the performance of clamping devices is one of the core factors that determine the overall smoothness of production.

[0003] Currently, most metal product clamping devices are four-jaw chucks, and the mainstream four-jaw chucks mostly use screw drive or ordinary gear drive structures. Although screw drive chucks have stable clamping force, the screw is prone to wear due to the intrusion of dust and other impurities, requiring frequent maintenance, and the clamping speed is relatively slow, making it difficult to meet the needs of high-efficiency processing; in ordinary gear drive chucks, the gears cannot be linked, resulting in accuracy deviations and poor clamping and fixing effects. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a metal product clamping device, which aims to solve the problems that existing clamping devices are difficult to adapt to the needs of high-efficiency processing and have poor clamping and fixing effects.

[0005] The present invention adopts the following technical solution:

[0006] The metal product clamping device includes a fixed base, a card slot on the front of the fixed base, four slots spaced apart on the card slot, a claw on the fixed base opposite each slot, the claw being located in the slot, a clamping assembly for driving the claw to move inside the fixed base, a slider forming the tail of the claw, the slider being slidably mounted inside the fixed base, racks forming on both the left and right sides of the slider, a sliding gear and a rotating gear rotatably mounted on the left and right sides of each slider inside the fixed base, a linkage gear coaxially mounted on the sliding gear, the sliding gear and the rotating gear respectively meshing with the racks at the same position, the clamping assembly including a drive gear and a clamping cylinder rotatably mounted inside the fixed base, the drive gear meshing with the linkage gear at the same position, and the drive shaft of the clamping cylinder being rotatably connected to the eccentric position of the drive gear via a short column.

[0007] Furthermore, the fixed base includes a cylinder with a pair of front and rear discs on the cylinder. A matching connecting sleeve is fitted between the two discs. A toothed disc is rotatably provided at the middle position on the back of the front disc, and the toothed disc meshes with each linkage gear.

[0008] Furthermore, each slider is provided with a slide block inside the front disc, the slider is located inside the slide block, and arc-shaped clearance grooves are opened on both the left and right sides of the slide block.

[0009] Furthermore, the fixed base is provided with a lifting ring.

[0010] The beneficial effects of this utility model are:

[0011] 1. This device is equipped with four jaws, which work together to clamp metal products, and can limit and fix the metal products from multiple directions, greatly improving the stability and positioning accuracy of clamping.

[0012] 2. The clamping assembly is driven by a clamping cylinder to rotate the drive gear, which in turn drives the linkage gear to rotate, which in turn drives the sliding gear to rotate. The sliding gear and the rotating gear work together to achieve sliding of the slider through meshing with the racks on both sides of the slider, thereby driving the chuck to move and completing the clamping or releasing action of the metal product.

[0013] 3. At the same time, the gear plate on the back of the front disc meshes with each linkage gear, which can ensure that multiple linkage gears rotate synchronously, thereby ensuring the synchronous action of the four chucks and improving the consistency of clamping.

[0018] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0019] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0020] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0021] Combination Figure 1-4As shown, the metal product clamping device includes a fixed base, a card seat 2 on the front of the fixed base, four slots 3 spaced apart on the card seat 2, a claw 4 opposite each slot 3 on the fixed base, the claw 4 being located in the slot 3, a clamping assembly for driving the claw 4 to move is provided in the fixed base, a slider 5 is formed at the tail of the claw 4, the slider 5 is slidably installed in the fixed base, racks 6 are formed on both the left and right sides of the slider 5, a sliding gear 7 and a rotating gear 8 are rotatably provided on the left and right sides of each slider 5 in the fixed base respectively, a linkage gear 16 is coaxially provided on the sliding gear 7, the sliding gear 7 and the rotating gear 8 respectively mesh with the racks at the same position, the clamping assembly includes a drive gear 9 and a clamping cylinder 10 rotatably installed in the fixed base, the drive gear 9 meshes with the linkage gear 16 at the same position, and the drive shaft of the clamping cylinder 10 is rotatably connected to the eccentric position of the drive gear 9 through a short column 11.

[0022] In this embodiment, the clamping device is mounted on the moving end of the transfer device via a fixed base. When using this device to clamp the workpiece, all four jaws are open. The metal product is then placed on the clamping base, with the metal product positioned within the four jaws. The clamping assembly then operates simultaneously, moving the corresponding jaws inward until all four jaws clamp the metal product. Finally, the transfer device moves the clamping device to the next workstation.

[0023] When the clamping assembly drives the jaws to clamp the metal workpiece, the clamping cylinder starts to work. The clamping cylinder drives the drive gear to rotate through the short column. The drive gear drives the linkage gear that meshes with it to rotate. The linkage gear drives the sliding gear connected to the same axis to rotate. The sliding gear cooperates with the rotating gear and, through meshing with the racks on both sides of the slider, drives the slider to slide in the slide block, which in turn drives the jaws to move along the jaw groove. The four jaws work together to clamp the metal product.

[0024] In this device, such as Figure 1-2 The fixed base serves as the main mounting body for the entire clamping device. The fixed base includes a cylinder 1.1, on which a pair of front and rear discs 1.2 are mounted. A matching connecting sleeve 1.3 is fitted between the two discs 1.2. This structural design enhances the overall strength and stability of the fixed base. A geared disc 12 is rotatably mounted at the center of the back of the front disc 1.2, and the geared disc 12 meshes with each linkage gear 16. The geared disc plays a crucial role in the device's transmission system, transmitting power and achieving synchronous movement of the jaws. That is, when the clamping cylinder drives the drive gear to rotate, the linkage gear at the same position rotates accordingly. Under the action of the geared disc, all linkage gears rotate synchronously, causing all sliding gears to rotate synchronously, ensuring that the four jaws can simultaneously and evenly apply clamping force to the workpiece.

[0025] In addition, such as Figure 4 The front disc has a slide block 13 directly opposite each slider 5, and the slider 5 is located inside the slide block 13. Arc-shaped clearance grooves 14 are formed on both the left and right sides of the slide block 13. In this structure, the slide block provides precise guidance for the slider's movement, ensuring that the slider maintains a stable trajectory during movement. The arc-shaped clearance grooves allow the sliding gear and rotating gear to better mesh with the rack.

[0026] In addition, the fixed base is provided with a lifting ring 15. By providing a lifting ring on the fixed base, the lifting rope of the lifting device can be used to fix the lifting ring to the device before lifting it.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
