Description

Technical Field

[0001] This invention belongs to the field of metal processing technology, and specifically relates to a mechanism for repairing U-shaped springback products. Background Technology

[0002] Due to the large size of the product, the uneven structure of the material, and the simple mold structure, the product springs back due to the elasticity of the material, causing the opening size of the product to be out of tolerance by 60-65mm. This fails to meet the customer's requirements for the relevant dimensions of the opening (63.5+ / -0.5mm). Therefore, there is an urgent need for a mechanism to repair spring-backed products so that they can meet the customer's needs. Summary of the Invention

[0003] The present invention aims to overcome the shortcomings of the prior art by providing a mechanism for repairing rebound products.

[0004] This invention is achieved through the following technical solution:

[0005] A mechanism for repairing U-shaped rebound products includes a base, a positioning component, and an adjustment component;

[0006] The positioning component includes a clamping block, a fixing seat, a screw bracket, a screw, and a guide post, and the positioning component is located on the left side of the upper surface of the base; the adjusting component includes a meshing gear set and a pressure rod, and the adjusting component is located on the right side of the upper surface of the base;

[0007] The screw holder is fixedly mounted on the base, and the guide post is installed in the first guide post hole of the screw holder and extends to the right; the clamping block is slidably mounted on the part of the guide post that extends out of the screw holder; a transverse through threaded hole is provided at the center of the screw holder, and the screw is installed through the threaded hole of the screw holder, and a magnet is embedded in the left side of the clamping block at the position corresponding to the outer end of the screw; the fixing seat is located on the right side of the clamping block and is fixedly mounted on the base;

[0008] The meshing gear set includes two meshing gears of the same size. Each gear is rotatably mounted on the base via a rotating shaft, and the meshing tangent of the meshing gear set coincides with the center line of the positioning component. Each gear has a notch on its left side. A pressure rod is fixedly connected to each gear. By moving the pressure rod, the meshing gear set is rotated, so that the notches of the two gears in the meshing gear set can simultaneously move the parallel plate for straightening the U-shaped workpiece.

[0009] In the above technical solution, the screw holder, clamping block and fixing seat are located on the base, and the centers of the three are on the same straight line.

[0010] In the above technical solution, a second guide post hole is provided laterally on the clamping block at the position corresponding to the first guide post hole of the screw bracket.

[0011] In the above technical solution, during operation, the intermediate connecting plate of the U-shaped workpiece to be corrected is clamped between the fixed seat and the clamping block.

[0012] In the above technical solution, a through hole is provided in the center of the intermediate connecting plate of the U-shaped workpiece. Correspondingly, a positioning protrusion is provided on the fixing seat. The protrusion is inserted into the through hole in the center of the intermediate connecting plate of the U-shaped workpiece for positioning.

[0013] In the above technical solution, the base is provided with fixed base bolt holes, and the mechanism for repairing the rebound product can be fixed on the working platform with holes by bolts.

[0014] In the above technical solution, a fixture rack is also provided on the base for placing inspection tools to inspect whether the angle between the two parallel plates of the U-shaped workpiece meets the requirements.

[0015] In the above technical solution, a scale is drawn on the upper surface of each gear, and a scale indicator head is set on the periphery of each gear. During the correction process, by cooperating with the scale on the gear and the scale indicator head, it is possible to know how much force is usually used, which is convenient for summarizing the experience of the amount of force used, thereby improving repair efficiency.

[0016] The method of using this invention is as follows:

[0017] Step 1: Place the middle connecting plate of the U-shaped workpiece in the gap between the fixed seat and the clamping block, so that the two parallel plates of the U-shaped workpiece are located in the notches of the two gears of the meshing gear set;

[0018] Step 2: Rotate the screw forward to push the clamping block along the direction of the guide post, thereby clamping the middle connecting plate of the U-shaped workpiece between the fixed seat and the clamping block.

[0019] Step 3: Use a testing tool to check the opening size of the two parallel plates of the U-shaped workpiece. After confirming whether the size exceeds the upper or lower tolerance, prepare to correct the U-shaped workpiece.

[0020] Step four: When the dimensions of the U-shaped workpiece exceed the upper tolerance, operate the pressure rod to drive the meshing gear set to pry the two parallel plates of the U-shaped workpiece inward, making the opening of the U-shaped workpiece smaller; conversely, operate the pressure rod to drive the meshing gear set to pry the two parallel plates of the U-shaped workpiece outward, making the opening of the U-shaped workpiece larger. Then, use a testing tool to verify. If it can smoothly enter the testing tool, it proves that the dimensions of the U-shaped workpiece meet the customer's requirements; if it does not meet the requirements, continue operating the pressure rod until the U-shaped workpiece is qualified.

[0021] Step 5: After the U-shaped workpiece is properly calibrated, rotate the screw in the opposite direction to allow it to come out to the left. As the screw comes out to the left using the magnet at the end of the screw, the clamping block is attracted and moved to the left along the guide post, thereby allowing the U-shaped workpiece to come out of the clamping of the fixed seat and the clamping block. Finally, remove the U-shaped workpiece from the gap between the fixed seat and the clamping block.

[0022] The advantages and beneficial effects of this invention are as follows:

[0023] The positioning component of this invention has a simple structure. By tightening the clamping block with screws, the clamping block clamps the U-shaped workpiece with the fixed seat, thereby positioning the U-shaped workpiece. The adjustment component of this invention adjusts the opening size of the U-shaped workpiece by simultaneously moving the meshing gear set, thereby preventing the U-shaped workpiece from being subjected to asynchronous forces.

[0027] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0028] A mechanism for repairing U-shaped rebound products, see appendix. Figure 1 - Appendix Figure 2 It includes a base 1, a positioning component, and an adjustment component.

[0029] The positioning component includes a clamping block 2, a fixing seat 3, a screw bracket 4, a screw 5, and a guide post 6, and the positioning component is located on the left side of the upper surface of the base 1; the adjusting component includes a meshing gear set 7 and a pressure rod 8, and the adjusting component is located on the right side of the upper surface of the base 1.

[0030] The screw holder 4, clamping block 2, and fixing base 3 are located on the base 1, and their centers are on the same straight line. The screw holder 4 is fixedly installed on the base 1. A first transverse guide post hole a1 is provided at each of the four corners of the screw holder 4. The guide post 6 is installed in the first guide post hole a1 of the screw holder 4 and extends to the right. A second transverse guide post hole a2 is provided at each of the four corners of the clamping block 2, corresponding to the position of the first guide post hole a1 of the screw holder 4. The clamping block 2 is slidably installed on the portion of the guide post 6 extending out of the screw holder 4. A transverse guide post a2 is provided at the center of the screw holder 4. The screw 5 is installed through the threaded hole b in the screw holder 4. A magnet c is embedded on the left side of the clamping block 2 at the position corresponding to the outer end of the screw 5. This allows the clamping block 2 and the outer end of the screw 5 to generate mutual attraction, so that when the screw 5 is withdrawn to the left from the screw holder 4, it can attract and drive the clamping block 2 to move to the left along the guide post 6. The fixing seat 3 is located on the right side of the clamping block 2 and is fixedly installed on the base 1. During operation, the middle connecting plate 9-1 of the U-shaped workpiece 9 to be corrected is clamped between the fixing seat 3 and the clamping block 2. Furthermore, the middle connecting plate 9-1 of the U-shaped workpiece 9 has a through hole in its center. Correspondingly, a positioning protrusion 3-1 is provided on the fixing seat 3. The protrusion 3-1 can be inserted into the through hole in the center of the middle connecting plate 9-1 of the U-shaped workpiece 9 for positioning.

[0031] The meshing gear set 7 includes two meshing gears of the same size. Each gear is rotatably mounted on the base 1 via a rotating shaft 11, and the meshing tangent of the meshing gear set 7 coincides with the center line of the positioning component. Each gear has a notch d on its left side. In use, the right ends of the two parallel plates 9-2 of the U-shaped workpiece 9 are inserted into the notch d. Scales (not shown in the figure) are drawn on the upper surface of each gear, and scale indicator heads 10 are provided around the periphery of each gear. A pressure rod 8 is fixedly connected to each gear. By moving the pressure rod 8, the meshing gear set 7 is rotated, so that the notches of the two gears of the meshing gear set 7 can simultaneously move the parallel plates 9-2 of the U-shaped workpiece 9 to correct it. During the correction process, the scales on the gears and the scale indicator heads 10 can be used to determine the amount of force used, facilitating the summarization of experience in applying force and thus improving repair efficiency.

[0032] The base 1 is provided with a fixing base bolt hole e, which can be used to fix the mechanism for repairing the rebound product to the working platform with holes.

[0033] The base 1 is also provided with a fixture rack 12 for placing inspection tools to inspect whether the angle between the two parallel plates 9-2 of the U-shaped workpiece 9 meets the requirements.

[0034] The method of using this invention is as follows:

[0035] Step 1: Place the intermediate connecting plate 9-1 of the U-shaped workpiece 9 in the gap between the fixed seat 3 and the clamping block 2, so that the two parallel plates 9-2 of the U-shaped workpiece 9 are located in the notches of the two gears of the meshing gear set 7, and the through hole of the intermediate connecting plate 9-1 of the U-shaped workpiece 9 is positioned on the positioning protrusion 3-1 of the fixed seat 3.

[0036] Step 2: Rotate screw 5 in the forward direction to push clamping block 2 to move along guide post 6, thereby clamping the middle connecting plate 9-1 of U-shaped workpiece 9 between fixed seat 3 and clamping block 2.

[0037] Step 3: Use a testing tool to check the opening size of the two parallel plates 9-2 of the U-shaped workpiece 9. After confirming whether the size exceeds the upper or lower tolerance, prepare to correct the U-shaped workpiece 9.

[0038] Step 4: When the dimensions of the U-shaped workpiece exceed the tolerance (the opening is too large), operate the pressure rod 8 to drive the meshing gear set 7 to pry the two parallel plates 9-2 of the U-shaped workpiece inward, making the opening of the U-shaped workpiece smaller; conversely, operate the pressure rod 8 to drive the meshing gear set 7 to pry the two parallel plates 9-2 of the U-shaped workpiece outward, making the opening of the U-shaped workpiece larger; then use the inspection tool to verify. If it can be smoothly inserted into the inspection tool, it proves that the dimensions of the U-shaped workpiece meet the customer's requirements; if it does not meet the requirements, continue operating the pressure rod 8 until the U-shaped workpiece 9 is qualified.

[0039] Step 5: After the U-shaped workpiece 9 is corrected to the required standard, rotate the screw 5 in the opposite direction to make the screw 5 come out to the left. During the process of the screw coming out to the left by the magnet at the end of the screw 5, the clamping block 2 is attracted and moved to the left along the guide post 6, thereby making the U-shaped workpiece 9 separate from the clamping block of the fixed seat. Finally, the U-shaped workpiece 9 is taken out from the gap between the fixed seat and the clamping block.

[0040] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0041] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0042] The present invention has been described above by way of example. It should be noted that any simple modifications, alterations or other equivalent substitutions that can be made by those skilled in the art without creative effort without departing from the core of the present invention fall within the protection scope of the present invention.
