Description

Technical Field

[0001] This utility model relates to the field of steel leaf spring processing technology, specifically to a positioning fixture for processing automotive steel leaf springs. Background Technology

[0002] Leaf springs are a common component of automotive suspension systems, used to support and connect the chassis and body of a car. They consist of multiple layers of bent steel plates and are installed between the wheels and chassis of a vehicle, providing support and shock absorption. During the manufacturing process of automotive leaf springs, the raw steel plates are bent and assembled to form the shape of a spring.

[0003] The existing patent (publication number: CN218363525U) discloses a clamping fixture for processing leaf springs. It horizontally positions the leaf spring by pressing down from the top, thereby fixing its center position. In conjunction with the clamping components, the leaf spring is further centered, thus effectively aligning the center point of the leaf spring with the drilling point.

[0004] However, the above technical solution still has certain defects. The device centers the leaf spring through the clamping component, but the clamping device can only center the leaf spring in the longitudinal direction and cannot center it in the lateral direction, which lacks certain applicability. At the same time, it is easy to deviate when drilling. Therefore, a positioning fixture for processing automotive leaf springs is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a positioning fixture for processing automotive leaf springs, so as to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for processing automotive leaf springs, including a worktable, with clamping and positioning components provided on both sides of the top of the worktable, and a collecting component slidably connected inside the worktable;

[0007] The clamping and positioning assembly includes two sets of movable plates slidably connected to the front and rear ends of the worktable. The two sets of movable plates are rotatably connected by a bidirectional threaded screw, and clamping blocks are fixed on both sides of the top of the movable plates. A base rod is rotatably connected inside the worktable. A gear is fixed to the top of the surface of the base rod. The gear has meshing racks on both the front and rear sides. A U-shaped frame is fixedly connected to one end of each set of racks. A connecting plate is fixed to the front end of one set of racks. An electric push rod is installed on the front end face of the worktable on one side of the connecting plate. A pressure plate is slidably connected to the inside of the U-shaped frame. A limit spring is installed on the top of the pressure plate.

[0008] As a preferred technical solution, a spring steel plate is placed on the top of the workbench, and the spring steel plate is fixed by a clamping block.

[0009] As a preferred technical solution, both sides of the two sets of movable plates are slidably connected to guide shafts, and the ends of the bidirectional threaded screws are fixed with knobs.

[0010] As a preferred technical solution, the U-shaped frame is slidably connected to both sides of the top of the workbench.

[0011] As a preferred technical solution, a slider is fixed on one side of the pressure plate, and a groove for the slider to move is opened on the inner side of the U-shaped frame.

[0012] As a preferred technical solution, the collection component includes a horizontal plate that fits against one side of the workbench, with two round shafts fixed to one side of the horizontal plate, and a collection frame fixed to the end of each of the two sets of round shafts away from the horizontal plate.

[0013] As a preferred technical solution, the bottom end of the moving plate and the top end of the collection frame are at the same horizontal position.

[0014] In summary, the present invention has the following main advantages:

[0015] 1. This utility model uses a knob to rotate a bidirectional threaded screw, which moves two movable plates relative to each other until the clamping blocks on both sides are in contact with the sides of the spring steel plate, achieving lateral centering. Then, an electric push rod moves the U-shaped frames on both sides inward. The pressure plate keeps the spring steel plate in a horizontal position, preventing one end from tilting up. The movement of the U-shaped frames keeps the spring steel plate longitudinally centered. Finally, the bidirectional threaded screw is tightened to fix the clamping blocks to the spring steel plate for drilling. By performing bidirectional centering of the spring steel plate, offset during drilling is better avoided, improving the applicability of the device.

[0016] 2. This utility model can push the debris that falls during drilling into the collection frame by moving the moving plate, thereby improving the cleanliness of the workbench. By pulling the horizontal plate, the round shaft moves the collection frame out of the workbench, making it easier to clean the collected debris. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] A positioning fixture for machining automotive leaf springs, such as Figure 1-4 As shown, it includes a worktable 100, with clamping and positioning components 200 on both sides of the top of the worktable 100, and a collection component 300 slidably connected inside the worktable 100.

[0027] The clamping and positioning assembly 200 includes two sets of movable plates 210 slidably connected to the front and rear ends of the worktable 100. The two sets of movable plates 210 are rotatably connected by a bidirectional threaded screw 220. Clamping blocks 230 are fixed on both sides of the top of the movable plates 210. A base rod 241 is rotatably connected inside the worktable 100. A gear 240 is fixed on the top of the surface of the base rod 241. A gear rack 250 is provided on both the front and rear sides of the gear 240. A U-shaped frame 280 is fixedly connected to one end of each set of gear racks 250. A connecting plate 260 is fixed to the front end of one set of gear racks 250. An electric push rod 270 is installed on one side of the connecting plate 260 and mounted on the front end of the worktable 100. A pressure plate 290 is slidably connected inside the U-shaped frame 280. A limit spring 2910 is installed on the top of the pressure plate 290.

[0028] Place the spring steel plate 110 on the workbench 100. Turn the knob 221 to cause the double-threaded screw 220 to move the two moving plates 210 relative to each other until the clamping blocks 230 on both sides are in contact with the sides of the spring steel plate 110, achieving lateral centering. Then, the electric push rod 270 drives the connecting plate 260 to move, causing the connecting plate 260 to drive a set of racks 250 to move. The racks 250 drive the gears 240 to rotate, thereby causing another set of racks 250 to move relative to each other, so that the two sets of racks 250 drive... The U-shaped frames 280 on both sides move inward, and the pressure plate 290 keeps the spring steel plate 110 in a horizontal position, preventing one end from tilting up. The movement of the U-shaped frames 280 can center the spring steel plate 110 longitudinally. Then, the double-threaded screw 220 is tightened, and the clamping block 230 fixes the spring steel plate 110 for drilling. By centering the spring steel plate 110 in both directions, the offset during drilling can be better avoided, improving the applicability of the device.

[0029] Please refer to this carefully. Figure 1 and Figure 2 A spring steel plate 110 is placed on the top of the workbench 100, and the spring steel plate 110 is fixed by a clamping block 230.

[0030] Multiple sets of clamping blocks 230 can better clamp and fix the spring steel plate 110, preventing it from shaking during drilling.

[0031] Please refer to this carefully. Figures 2 to 4 The two sets of movable plates 210 are slidably connected to guide shafts 211 on both sides inside. The end of the bidirectional threaded screw 220 is fixed with a knob 221. The U-shaped frame 280 is slidably connected to both sides of the top of the workbench 100. The pressure plate 290 is fixed with a slider 291 on one side. The inner side of the U-shaped frame 280 is provided with a groove 292 for the slider 291 to move.

[0032] By setting the guide shaft 211, the moving plate 210 can be made more stable when moving. By setting the knob 221, it is easy to turn the bidirectional threaded screw 220. By the cooperation of the slider 291 and the slide groove 292, the pressure plate 290 can better abut against the top sides of the spring steel plate 110.

[0033] Please refer to this carefully. Figure 3 The collection component 300 includes a horizontal plate 310 attached to one side of the workbench 100.

The bottom end of the moving plate 210 and the top end of the collection frame 330 are at the same horizontal position.

[0034] The movement of the movable plate 210 can push the debris that falls during drilling into the collection frame 330 for collection, improving the cleanliness of the workbench 100. By pulling the horizontal plate 310, the round shaft 320 can move the collection frame 330 out of the workbench 100, making it easier to clean the collected debris.

[0035] In use, place the spring steel plate 110 on the workbench 100, turn the knob 221 to make the double-sided threaded screw 220 drive the moving plates 210 on both sides to move relative to each other until the clamping blocks 230 on both sides are in contact with the sides of the spring steel plate 110, achieving horizontal centering. Then, the electric push rod 270 drives the U-shaped frames 280 on both sides to move inward. The pressure plate 290 can keep the spring steel plate 110 in a horizontal position to prevent one end from tilting up. The movement of the U-shaped frame 280 can keep the spring steel plate 110 in a vertical center. Then tighten the double-sided threaded screw 220 to make the clamping blocks 230 The spring steel plate 110 is fixed for drilling operations. By centering the spring steel plate 110 in both directions, the deviation during drilling can be better avoided, improving the applicability of the device. The movement of the moving plate 210 can push the debris falling during drilling into the collection frame 330 for collection, improving the cleanliness of the workbench 100. By pulling the horizontal plate 310, the round shaft 320 moves the collection frame 330 out of the workbench 100, making it easier to clean the collected debris. The parts of this device not mentioned are the same as or can be implemented using existing technology.
