Description

Technical Field

[0001] This utility model relates to the field of clamp tooling technology, and in particular to a tooling for manufacturing curved clamps. Background Technology

[0002] The curved clamp fixture is a special auxiliary tool adapted to curved clamps. Its core consists of a contour positioning component, a clamping and fixing structure, and a support frame. It is mainly used in the clamp processing or assembly process. First, the positioning groove and positioning pin that match the curvature of the clamp are used to determine the precise position of the workpiece, so as to avoid the clamp from shifting during dimensional calibration, and ultimately ensure the clamp accuracy and processing stability.

[0003] Most of the tooling is used to process curved clamps. The main body is an annular boss with two locating pins on the outside of the boss, corresponding to the two bolt holes of the clamp, which are used to fix the clamp. After fixing, a pin is used to press the flattened part of the clamp through the reserved hole on the inner boss. However, during processing, if the pin presses the flattened part of the clamp, the displacement is limited only by the cooperation between the pin and the hole. The clamp is prone to shifting, resulting in deviation in processing accuracy. In addition, the locating pin and the bolt hole of the clamp are in hard contact, and the hole wall is easily scratched when inserting the pin.

[0004] Therefore, it is necessary to provide a new tooling for manufacturing curved clamps to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model 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 present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 4 A tooling for manufacturing curved clamps includes: a base 1, with limiting rods 2 symmetrically fixedly connected to the top of the base 1. The limiting rods 2 are vertical and parallel to each other. A carrying plate 3 is placed between the two limiting rods 2 at the top of the base 1. Limiting blocks 4 are fixedly connected to both the left and right ends of the carrying plate 3. The inner wall of the limiting block 4 is interlocked with the outer side of the limiting rod 2. The bottom end of the limiting block 4 is in contact with the top of the base 1. An arc-shaped protrusion 5 is fixedly connected to the top of the carrying plate 3. A clamp body 6 is placed outside the arc-shaped protrusion 5. The shape of the arc-shaped protrusion 5 is adapted to the inner curvature of the curved clamp.

[0024] Support plate 7 is fixedly connected to the rear top of base 1. Fixing plate 8 is fixedly connected to the top front of support plate 7. Electric push rod 9 is fixedly connected to the top of fixing plate 8, providing a platform for its installation. Connecting plate 10 is fixedly connected to the drive end of electric push rod 9. When the drive end of electric push rod 9 extends or retracts, it can drive connecting plate 10 to move up and down. Sliding rods 11 are slidably connected to the inner walls of the four corners of connecting plate 10. Strong springs 12 are sleeved on the outside of sliding rods 11. A baffle 13 is fixedly connected to the top of sliding rod 11. The baffle 13 has a disc-shaped structure, and its diameter is larger than the diameter of the sliding rod 11. The bottom end of 3 contacts the top corner of the connecting plate 10, which can limit the downward sliding position of the sliding rod 11. The bottom ends of multiple sliding rods 11 are fixedly connected to pressure plates 14. The top end of the strong spring 12 is fixedly connected to the bottom end of the connecting plate 10, and the bottom end of the strong spring 12 is fixedly connected to the top end of the pressure plate 14. The bottom end of the pressure plate 14 is provided with an arc-shaped groove 15. The shape of the arc-shaped groove 15 is adapted to the outer arc of the curved clamp. The inner diameter of the arc-shaped groove 15 is larger than the outer diameter of the arc-shaped protrusion 5, which is used to fit the clamp body 6. When the pressure plate 14 moves downward, the arc-shaped groove 15 can fit tightly with the outer surface of the clamp body 6.

[0025] The tightening assembly is installed on the outside of the limiting rod 2. The tightening assembly includes two washers 16. The inner walls of the two washers 16 are interlocked with the outside of the limiting rod 2. A shock-absorbing spring 17 is sleeved between the two washers 16 on the outside of the limiting rod 2. A nut 18 is threadedly connected to the external thread of the limiting rod 2. By rotating the nut 18, the washers 16 and the shock-absorbing spring 17 can be pressed. The bottom of the bottom washer 16 contacts the top of the limiting block 4, and the top of the top washer 16 contacts the bottom of the nut 18. The two ends of the shock-absorbing spring 17 are fixedly connected to the adjacent side of the two washers 16. When the nut 18 is tightened, the shock-absorbing spring 17 can be compressed through the washer 16, and the elastic force of the shock-absorbing spring 17 can be used to stably fix the carrying plate 3 on the base 1.

[0026] The working principle of the tooling for manufacturing curved clamps provided by this utility model is as follows:

[0027] When processing a curved clamp, the first step is to prepare and place the workpiece. The worker places the clamp body 6 on the arc-shaped protrusion 5 at the top of the carrier plate 3. The arc-shaped protrusion 5 provides initial shape adaptation and support for the clamp body 6, so that the clamp body 6 is stably in the position to be processed. At the same time, the carrier plate 3 cooperates with the limiting blocks 4 at the left and right ends and the limiting rods 2 symmetrically arranged on the base 1 to achieve the initial positioning of the carrier plate 3 on the base 1, ensuring that the carrier plate 3 will not move arbitrarily during subsequent processing.

[0028] Next, the electric push rod 9 is activated. The electric push rod 9 begins to work, its drive end extends, causing the connecting plate 10 to move downwards. During the downward movement of the connecting plate 10, because the inner walls at its four corners are slidably connected to the sliding rods 11, and the sliding rods 11 are fitted with strong springs 12, as the connecting plate 10 moves downwards, they push the sliding rods 11 downwards synchronously, thereby causing the pressure plate 14 to move closer to the clamp body 6. As the pressure plate 14 continuously approaches the clamp body 6, the arc-shaped groove 15 at the bottom of the pressure plate 14 gradually comes into contact with the clamp body 6 and the arc-shaped protrusion 5. Because the inner diameter of the arc-shaped groove 15 is larger than the outer diameter of the arc-shaped protrusion 5, it can better fit the clamp body 6 during the contact process. During processing, the strong spring 12 will generate elastic force due to compression. This elastic force is used to allow the pressure plate 14 to flexibly press the clamp body 6, avoiding damage to the clamp body 6 from hard contact. At the same time, it stably fixes the clamp body 6 between the arc-shaped protrusion 5 and the pressure plate 14. At this time, the ejector pin inside the arc-shaped protrusion 5 can start to work. If the machine vibrates during processing, the tightening component on the limit rod 2 will play a role. The nut 18, washer 16, and shock-absorbing spring 17 work together to turn the pressure given to the shock-absorbing spring 17 when the nut 18 is tightened into a rebound force. This rebound force can increase the thread friction between the nut 18 and the limit rod 2, reduce the risk of the nut loosening, and maintain the stability of the position of the carrier plate 3.

[0029] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
