Description

Technical Field

[0001] This utility model relates to the field of metal product testing fixtures, specifically a metal product testing fixture. Background Technology

[0002] Metal products are items made of metal materials. After the metal products are processed, they need to be tested for mechanical properties. Generally, the metal products to be tested are clamped on a fixture for testing.

[0003] For example, the utility model disclosed in publication (announcement) number CN219685338U discloses a metal product testing fixture, including a base block. A connecting groove is opened on the top outer wall of the base block, and an adjusting screw is rotatably connected to the inside of the connecting groove through a bearing. A slider is threadedly connected to the outside of the adjusting screw, and the slider is located on the top outer wall of the base block. A support block is welded to one side outer wall of the slider, and a fixing rod is welded to the top outer wall of the support block. A clamping block is sleeved on the outside of the fixing rod, and the clamping block is located on the top outer wall of the slider. A fixing sleeve is threadedly connected to the outside of the fixing rod, and the fixing sleeve is located on the top outer wall of the clamping block. A fixing groove is opened on one side outer wall of the clamping block, and a clamping block is slidably connected inside the fixing groove. This utility model, through the setting of the slider, support block, and clamping block, allows the operator to easily adjust the angle of the clamping block during use, thereby enabling the clamping of different surfaces of metal products and improving the clamping effect on irregular metal products.

[0004] The aforementioned fixture facilitates the adjustment of the angle of the clamping blocks, thereby clamping different surfaces of the metal product. However, its clamping blocks only have a planar structure to clamp the two sides of the metal product. When fixing the two ends of the arc-shaped metal product, it only clamps and fixes through point contact, which is not convenient for clamping and fixing the two sides of the arc-shaped metal product. Utility Model Content

[0005] The purpose of this utility model is to provide a metal product testing fixture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal product testing fixture, comprising a base block with a groove, and rotating rods rotatably connected to both sides of the groove in a horizontal direction. One end of the rotating rod rotatably passes through one side of the groove and extends to the outside of the base block. A motor is fixedly installed on one side of the base block, and the output end of the motor is fixedly installed to the end of the rotating rod extending to the outside of the base block via a coupling. Threaded sleeves are threaded onto both sides of the rotating rod, and a movable plate is fixedly connected to the top of each threaded sleeve. A rotating shaft is rotatably installed at the center of the top of the movable plate, and a clamping assembly is fixedly connected to the top of the rotating shaft.

[0007] Preferably, the rotating rod has a threaded structure on both sides of the groove in the bottom block, with the helical direction opposite to that of each threaded sleeve block.

[0008] Preferably, the bottom end of each threaded sleeve is adapted to the shape of the inner wall of the groove and makes smooth contact.

[0009] Preferably, each of the clamping components includes a positioning plate fixedly connected to the top of each rotating shaft, and each positioning plate has through holes on both sides that are threaded with the screw, and the movable plate has mounting holes on both sides that are threaded with the screw.

[0010] Preferably, each positioning plate has a flat clamping plate and an arc-shaped clamping plate fixedly connected to both sides, and the bottom of the flat clamping plate and the arc-shaped clamping plate, which are far apart from each other, are respectively fixedly connected to a support plate.

[0011] Preferably, each of the arc-shaped clamping plates has an arc-shaped groove in the vertical direction on the side away from the flat clamping plate, and a protrusion is fixedly installed at the center of the top of the positioning plate.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] This invention controls a motor to drive a rotating rod through its output end. The rotating rod, with its opposing spiral threads, drives corresponding threaded blocks to move two movable plates closer together or further apart. The threaded blocks are designed to fit the shape of the groove's inner wall and make smooth contact, ensuring each block can only move horizontally within the groove without rotation. When the two movable plates move closer or further apart, a positioning plate fixedly connected to the top of each movable plate clamps one end of the metal product using a flat clamping plate and an arc-shaped clamping plate on one side. Each support plate supports the bottom of the metal product. The flat clamping plate clamps both ends of a flat metal product. When clamping both ends of an arc-shaped metal product, each screw is removed, and the protrusion is rotated to rotate each positioning plate, thus swapping the positions of the flat and arc-shaped clamping plates on each side. After fixing the positioning plate to the movable plate with screws, the arc-shaped grooves in the adjacent arc-shaped clamping plates clamp and fix both ends of the arc-shaped metal product.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Example 1

[0020] Please see Figures 1-3 The metal product testing fixture shown in the figure includes a base block 1 with a groove 8. Rotating rods 2 are rotatably connected to both sides of the groove 8 in the horizontal direction. One end of the rotating rod 2 is rotatably inserted through one side of the groove 8 and extends to the outside of the base block 1. A motor 3 is fixedly installed on one side of the base block 1, and the output end of the motor 3 is fixedly installed to the end of the rotating rod 2 extending to the outside of the base block 1 via a coupling. Threaded sleeve blocks 4 are threadedly sleeved on both sides of the rotating rod 2, and a movable plate 5 is fixedly connected to the top of each threaded sleeve block 4. A rotating shaft 6 is rotatably installed at the center of the top of the movable plate 5, and a clamping assembly 7 is fixedly connected to the top of the rotating shaft 6.

[0021] In this embodiment, the rotating rod 2 has a threaded structure on both sides of the groove 8 of the bottom block 1, which is opposite to the spiral direction of each threaded sleeve block 4. The bottom end of each threaded sleeve block 4 is adapted to the shape of the inner wall of the groove 8 and makes smooth contact. Each clamping assembly 7 includes a positioning plate 71 fixedly connected to the top end of each rotating shaft 6. Each positioning plate 71 has through holes on both sides that are threaded with the screw. The moving plate 5 has mounting holes on both sides that are threaded with the screw. Each positioning plate 71 has a flat clamping plate 72 and an arc-shaped clamping plate 73 fixedly connected to both sides. The flat clamping plate 72 and the arc-shaped clamping plate 73 are fixedly connected to the bottom of the ends of the flat clamping plate 72 and the arc-shaped clamping plate 73 respectively. Each arc-shaped clamping plate 73 has an arc-shaped groove 76 on the side away from the flat clamping plate 72 in the vertical direction. A protrusion 75 is fixedly installed at the center of the top end of the positioning plate 71.

[0022] Furthermore, by controlling the output end of the motor 3 to drive the rotating rod 2 to rotate, the threaded structure with opposite helical directions on the rotating rod 2 drives the corresponding threaded sleeve 4 to move the two moving plates 5 closer or further apart. The threaded sleeve 4 is set to fit the shape of the inner wall of the groove 8 and make smooth contact, so that each threaded sleeve 4 can only move horizontally within the groove 8 and will not rotate. When the two moving plates 5 move closer or further apart, the positioning plate 71 fixedly connected to the top of each moving plate 5 is held by a flat clamping plate 72 and an arc-shaped clamping plate 73 on one side. One end of the metal product is clamped and fixed. Each support plate 74 is used to support the bottom end of the metal product. The flat clamping plate 72 is used to clamp and fix both ends of the flat metal product. When it is necessary to clamp and fix both ends of the arc-shaped metal product, each screw is removed and the protrusion 75 is rotated to make each positioning plate 71 rotate accordingly, thereby exchanging the positions of the flat clamping plate 72 and the arc-shaped clamping plate 73 on each side. Then, the positioning plate 71 is fixed to the moving plate 5 by the screw. The arc-shaped groove 76 opened by the arc-shaped clamping plates 73 that are close to each other clamps and fixes both ends of the arc-shaped metal product.

[0023] The working principle of this utility model is as follows: By controlling the output end of the motor 3, the rotating rod 2 is driven to rotate. The rotating rod 2, with its opposing spiral threads, drives the corresponding threaded sleeves 4 to move the two moving plates 5 closer together or further apart. The threaded sleeves 4 are designed to fit the shape of the inner wall of the groove 8 and make smooth contact, ensuring that each threaded sleeve 4 can only move horizontally within the groove 8 without rotation. When the two moving plates 5 move closer or further apart, the positioning plate 71 fixedly connected to the top of each moving plate 5 is held in place by a flat clamping plate 72 and an arc-shaped clamping plate on one side. Plate 73 clamps and fixes one end of the metal product, and each support plate 74 is used to support the bottom end of the metal product. The flat clamping plate 72 is used to clamp and fix both ends of the flat metal product. When it is necessary to clamp and fix both ends of the arc-shaped metal product, each screw is removed and the protrusion 75 is rotated to make each positioning plate 71 rotate accordingly, thereby exchanging the positions of the flat clamping plate 72 and the arc-shaped clamping plate 73 on each side. Then, the positioning plate 71 is fixed to the moving plate 5 by the screw, and the arc-shaped groove 76 opened by the arc-shaped clamping plates 73 that are close to each other clamps and fixes both ends of the arc-shaped metal product.
