Description

Technical Field

[0001] This utility model relates to the field of metal workpiece technology, specifically a metal workpiece spraying positioning fixture. Background Technology

[0002] Metal workpieces refer to parts or products with specific shapes, sizes, and properties made from metal materials through processes such as machining, casting, forging, welding, and stamping. They are fundamental components in the industrial manufacturing field, widely used in various industries such as machinery, automobiles, aerospace, electronics, construction, and energy. They are indispensable components for the normal operation of various equipment and systems. The core characteristics of metal workpieces are: material properties: metal matrix: the main body of the workpiece is composed of metal or alloy, giving it high strength, hardness, toughness, electrical conductivity, thermal conductivity, and other properties; surface treatment: corrosion resistance, wear resistance, or decoration can be improved through coating, oxidation, spraying, etc. Metal workpieces are the basic units of the industrial system. Their design needs to balance function, process, and cost, and manufacturing needs to be integrated. With the evolution of materials, intelligent manufacturing, and environmental protection requirements, metal workpieces are continuously upgrading towards high performance, lightweight, and integration.

[0003] A search revealed Chinese patent application number 202420870325.4, which discloses a metal workpiece spraying positioning fixture. This application relates to the field of metal workpiece processing technology and discloses a metal workpiece spraying positioning fixture, including a base. Multiple fixed columns are fixedly connected to the top outer wall of the base. An inner support assembly for securing the workpiece is installed on the outer wall of each fixed column. The inner support assembly includes a bearing ring slidably connected to the outer wall of the fixed column, and a fixed block fixedly connected to the outer wall near the top of the fixed column. Multiple first connecting rods are hinged to the bottom outer wall of the fixed block, and multiple second connecting rods are hinged to the top outer wall of the bearing ring. A connecting member is movably connected to the opposite end of each second connecting rod and the first connecting rod. Inner support plates are fixedly connected to the outer walls of the multiple connecting members. In this invention, the inner support assembly drives multiple inner support plates to synchronously contract or expand. When the multiple inner support plates expand outward, they can clamp the metal workpiece, thus not affecting the uniformity of the spraying on the workpiece surface.

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.

[0021] like Figures 1 to 4 As shown, the present invention provides a metal workpiece spraying positioning fixture, including a workbench body 1, with anti-slip legs 2 fixedly connected to the bottom of the workbench body 1, a protective shell 3 fixedly connected to the center of the top of the workbench body 1, a stepper motor 4 provided at the bottom of the workbench body 1, a rotating gear 5 fixedly connected to the output end of the stepper motor 4, transmission gear plates 6 meshing on both sides of the rotating gear 5, a first clamping block 7 fixedly connected to the outer side of the transmission gear plate 6, a second clamping block 8 provided diagonally on the first clamping block 7, the bottom of the second clamping block 8 fixedly connected to the top of the workbench body 1, and a spraying assembly 9 provided on the top of the protective shell 3.

[0022] refer to Figure 2The spraying assembly 9 includes a water tank 91, which is located on top of the protective shell 3. A submersible pump 92 is installed inside the water tank 91. The output end of the submersible pump 92 is connected to a water pipe 93. The other end of the water pipe 93 is fixedly connected to a hose 94. The other end of the hose 94 is fixedly connected to a nozzle 95.

[0023] As a technical optimization of this utility model, by setting up the spraying component 9, the spraying component 9 can draw the cleaning liquid inside the water tank 91 through the submersible pump 92 and clean the paint adsorbed on the surface of the workbench body 1 through the nozzle 95.

[0024] refer to Figure 4 A support block 10 is fixedly connected to the bottom of the stepper motor 4, and the top of the support block 10 is fixedly connected to the bottom of the worktable body 1.

[0025] As a technical optimization of this utility model, by setting the support block 10, the stepper motor 4 can be limited by the support block 10 to prevent the stepper motor 4 from shaking during operation.

[0026] refer to Figure 1 Each of the top diagonal corners of the protective shell 3 has a limiting groove 11, and the first clamping block 7 is located inside the limiting groove 11.

[0027] As a technical optimization of this utility model, by setting the limiting slide groove 11, the first clamping block 7 can be limited by the limiting slide groove 11 to prevent the first clamping block 7 from shaking when moving.

[0028] refer to Figure 2 Both sides of the top of the workbench body 1 are provided with through holes 12, and a fixing block 13 is provided at the bottom of the nozzle 95. The other end of the fixing block 13 is fixedly connected to the right side of the top of the water tank 91.

[0029] As a technical optimization of this utility model, the cleaning liquid can be discharged through the through hole 12, and the nozzle 95 can be supported by the fixing block 13.

[0030] refer to Figure 3 A vertical block 14 is fixedly connected to the bottom of the transmission gear plate 6, and the bottom of the vertical block 14 is slidably connected to the top of the worktable body 1.

[0031] As a technical optimization of this utility model, the vertical block 14 can limit the transmission gear plate 6 and prevent the transmission gear plate 6 from shaking when moving.

[0032] The working principle and usage process of this utility model are as follows: When processing an object, the object is placed between the first clamping block 7 and the second clamping block 8. Then, the stepper motor 4 is started, and the output end of the stepper motor 4 begins to rotate, driving the connected rotating gear 5 to rotate. The rotation of the rotating gear 5 further drives the transmission gear plate 6 to move linearly. The movement of the transmission gear plate 6 pushes the first clamping block 7 to close towards the object, thereby achieving stable clamping of the object. When it is necessary to clean the paint adsorbed on the top of the workbench body 1, the operator first adds the cleaning fluid to the water tank 91, and then starts the submersible pump 92 to draw the liquid in the water tank 91 through the water pipe 93 and deliver it to the hose 94. The user holds the nozzle 95 and guides the cleaning fluid from the nozzle 95 through the hose 94 to spray it accurately onto the paint surface, completing the efficient cleaning operation. This realizes a continuous operation process from power transmission to clamping and positioning, and then to cleaning treatment.

[0033] In summary, this metal workpiece spraying positioning fixture, through the arrangement of components such as a protective shell, stepper motor, rotary gear, transmission gear plate, first clamping block, and second clamping block, drives the output end of the stepper motor to rotate, which in turn drives the rotary gear to rotate. The rotation of the rotary gear drives the transmission gear plate to move, and the movement of the transmission gear plate drives the first clamping block to cooperate with the second clamping block for positioning. This solves the problems of low positioning efficiency and complex operation of existing positioning fixtures when adapting to different types of objects, which leads to users having to repeatedly debug and spend time, making it difficult to meet the needs of quickly switching between processed parts.
