Description

Technical Field

[0001] This utility model relates to the field of flip-over clamping technology, and in particular to a flip-over clamping fixture. Background Technology

[0002] Reversible fixtures are a type of tooling widely used in industrial manufacturing. They feature a unique structural design and, through ingenious mechanical connections and transmission devices, enable workpieces to be flexibly flipped during processing. Their main frame is made of high-strength metal to ensure sufficient rigidity and stability to support workpieces of different sizes and weights.

[0003] A search revealed Chinese Patent Publication No. CN102941431B, which discloses a flipping clamp, including a support, a clamp body pivotally connected to the support via a rotating shaft, and a pushing mechanism for rotating the clamp body; the pushing mechanism includes a gear and rack pair and a first cylinder for reciprocating the rack; it also includes a positioning mechanism; the positioning mechanism includes a positioning disc disposed on the end of the rotating shaft and having at least two positioning grooves, a positioning pin meshing with the positioning disc, a second cylinder driving the positioning pin, a first limit switch linked to the rack and controlling the second cylinder, and a limit switch linked to the positioning pin and controlling the... The second limit switch of the first cylinder, through the positioning mechanism, not only improves the positioning accuracy of the fixture flipping, but also eliminates the positioning impact of the fixture due to the linkage between the first and second limit switches, thereby improving the positioning and reliability of the fixture and extending its service life. Existing flipping fixtures achieve the clamping effect by clamping the product with two clamping plates. However, this clamping method requires multiple lowering and lifting of the product when painting or coating it because the clamping plates on both sides block the view. This not only delays the work progress, but also causes uneven painting due to multiple painting, thus affecting the product quality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a flip-up clamp, which aims to improve the problem in the prior art where the flip-up clamp obstructs part of the product when clamping, resulting in the need to put it down and pick it up repeatedly during painting and coating, thus affecting the work progress and product quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flip-up clamp includes a frame, a fixed column rotatably connected to the right inner side of the frame, a fixed clamping wheel fixedly connected to the left side of the fixed column, a support rod slidably connected to the left side of the frame, a clamping wheel fixedly connected to the right end of the support rod, threaded rods rotatably connected to the upper and lower left ends of the fixed clamping wheel, the two threaded rods being threadedly connected to the clamping wheel, sprockets fixedly connected to the left ends of the two threaded rods, the two sprockets being mutually driven and connected by a chain, a throttle fixedly connected to the left side of the two sprockets, and a flipping mechanism installed in the upper middle part of the inner side of the frame, the flipping mechanism being used to flip the clamping device.

[0006] The above technical solution involves rotating any throttle to drive any sprocket, which in turn drives another sprocket to rotate synchronously via a chain. As both sprockets rotate, the two threaded rods fixed on the right side are also driven to rotate synchronously. These two threaded rods then drive the clamping wheel, which is fixed to the left side of the frame via a support rod, to move to the right. As the clamping wheel moves to the right, the distance between it and the fixed clamping wheel on the right side of the frame via a fixing post is continuously reduced, thus achieving the clamping effect on the product. At the same time, the hollow design of the fixed clamping wheel and the clamping wheel reduces the contact area between them when clamping the product.

[0007] As a further description of the above technical solution:

[0008] The flipping mechanism includes a connecting rod, the lower middle part of which is rotatably connected to the right side of the outer wall of the frame. A rocker arm is fixedly connected to the lower end of the connecting rod, and a bevel gear is fixedly connected to the upper end of the rocker arm. A rotating rod is rotatably connected to the upper middle part of the inner side of the frame, and a bevel gear is fixedly connected to the right end of the outer wall of the rotating rod. A flipping gear is fixedly connected to the right side of the rotating rod.

[0009] The above technical solution involves: rocking the rocker arm to drive the rotation of the connecting rod. When the connecting rod rotates, the first bevel gear fixed on it will also rotate synchronously. At the same time, the first bevel gear will drive the second bevel gear to rotate together through meshing. As the second bevel gear rotates, the rotating rod fixed on its left side will also rotate together. When the rotating rod rotates, the flipping gear fixed on it will also rotate together. When the flipping gear rotates, it can drive the fixed clamping wheel to rotate through meshing. When the fixed clamping wheel rotates, it will drive the clamping wheel to rotate together through the threaded rod fixed on it.

[0010] As a further description of the above technical solution:

[0011] Multiple anti-slip sleeves are equidistantly installed on the outer walls of the two throttles, and the front and rear ends of the multiple anti-slip sleeves are fixedly connected with Velcro.

[0012] The above technical solution involves using Velcro to secure the anti-slip sleeve to the outside of the throttle, thereby enhancing its anti-slip performance.

[0013] As a further description of the above technical solution:

[0014] A protective ring is fixedly connected to the left end of the outer wall of the support rod, and a limit block is fixedly connected to the left side of the support rod.

[0015] The above technical solution involves a limiting block that restricts the sliding range of the support rod, and a protective ring that provides cushioning between the limiting block and the frame.

[0016] As a further description of the above technical solution:

[0017] A rubber sleeve is fixedly connected to the outer wall of the rocker arm, and the outer surface of the rubber sleeve is provided with anti-slip texture.

[0018] The above technical solution involves fixing a rubber sleeve to the outside of the joystick, and the anti-slip texture on the outside enhances the joystick's grip.

[0019] As a further description of the above technical solution:

[0020] The top of the frame is fitted with a top rail, and each of the four corners of the top rail is threaded with a screw.

[0021] The above technical solution involves using screws to fix the top rail to the frame, providing protection for the top of the flip-up fixture.

[0022] As a further description of the above technical solution:

[0023] A workbench is fixedly connected to the lower right side of the inner side of the frame, and support columns are fixedly connected to the front and rear ends of the bottom left side of the workbench.

[0024] Through the above technical solution, the workbench, supported by the frame and support columns, can hold the product to be clamped.

[0025] As a further description of the above technical solution:

[0026] An X-shaped frame is installed on the rear side of the frame, and screws are threaded to the four corners of the X-shaped frame.

[0027] The above technical solution involves fixing the X-shaped frame to the back of the frame with screw two, thereby enhancing the stability of the frame.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, rotating the throttle drives two threaded rods to rotate via two sprockets and a chain, thereby moving the clamping wheel to the right to cooperate with the fixed clamping wheel to achieve the clamping effect on the product. The hollow design of the fixed clamping wheel and the clamping wheel reduces the contact area between the fixed clamping wheel and the clamping wheel when clamping the product, thereby reducing the number of times the product needs to be put down and picked up during painting and coating, thus improving work progress and product quality.

[0030] 2. In this utility model, the rocker arm drives the rotating rod and the flipping gear on it to rotate through the connecting rod, bevel gear one and bevel gear two. The flipping gear drives the fixed clamping wheel to rotate through meshing. When the fixed clamping wheel rotates, it will drive the clamping wheel to rotate together through the threaded rod fixed on it, thereby realizing the effect of flipping the clamped product.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 3 and Figure 4 This utility model provides an embodiment of a flip-up clamp, comprising a frame 1. A fixed post 3 is rotatably connected to the inner right end of the frame 1. A fixed clamping wheel 4 is fixedly connected to the left side of the fixed post 3 and is fixedly secured by the fixed post 3. A support rod 5 is slidably connected to the left side of the frame 1. A clamping wheel 6 is fixedly connected to the right end of the support rod 5, and the support rod 5 is used to fix the clamping wheel 6. Threaded rods 7 are rotatably connected to the upper and lower ends of the left side of the fixed clamping wheel 4. The two threaded rods 7 are threadedly connected to the clamping wheel 6, and the threaded rods 7 control the movement of the clamping wheel 6 through the threads. A sprocket 8 is fixedly connected to the left end of each of the two threaded rods 7. The two sprockets 8 are connected by a chain 9 for mutual transmission. A throttle 10 is fixedly connected to the left side of the two sprockets 8. The throttle 10, together with the chain 9, drives the two sprockets 8 to rotate. A flipping mechanism 2 is installed on the upper inner side of the frame 1. The flipping mechanism 2 is used to flip the clamping device. Multiple anti-slip sleeves 11 are installed at equal intervals on the outer wall of the two throttles 10. The front and rear ends of the multiple anti-slip sleeves 11 are fixedly connected with Velcro 12. The anti-slip sleeves 11 are fixed to the throttles 10 through Velcro 12. A protective ring 13 is fixedly connected to the left end of the outer wall of the support rod 5. A limit block 14 is fixedly connected to the left side of the support rod 5. The protective ring 13 and the limit block 14 are used to limit the sliding range of the support rod 5.

[0040] Specifically, by rotating any one of the throttle handles 10, any one of the sprockets 8 is driven to rotate. At this time, the sprocket 8 will drive the other sprocket 8 to rotate synchronously through the chain 9. When the two sprockets 8 rotate, the two threaded rods 7 fixed on the right side will also be driven to rotate synchronously. At this time, the two threaded rods 7 will drive the clamping wheel 6 fixed to the left side of the frame 1 through the support rod 5 to move to the right. As the clamping wheel 6 moves to the right, the distance between it and the fixed clamping wheel 4 fixed to the right side of the frame 1 through the fixing post 3 is continuously reduced, thereby achieving the clamping effect on the product. At the same time, the hollow design of the fixed clamping wheel 4 and the clamping wheel 6 reduces the contact area between the fixed clamping wheel 4 and the clamping wheel 6 when clamping the product, thereby reducing the number of times it is necessary to put down and pick up during painting and coating. The anti-slip sleeve 11 fixed to the outside of the throttle handle 10 by the Velcro 12 can improve the anti-slip performance of the throttle handle 10, while the limiting block 14 can limit the sliding range of the support rod 5, and the protective ring 13 can play a buffering role between the limiting block 14 and the frame 1.

[0041] Reference Figure 5 The flipping mechanism 2 includes a connecting rod 201. The lower middle part of the connecting rod 201 is rotatably connected to the right side of the outer wall of the frame 1. The lower end of the connecting rod 201 is fixedly connected to a rocker arm 202. The upper end of the rocker arm 202 is fixedly connected to a bevel gear 203. The rocker arm 202 drives the bevel gear 203 to rotate through the connecting rod 201. The upper middle part of the inner side of the frame 1 is rotatably connected to a rotating rod 204. The right end of the outer wall of the rotating rod 204 is fixedly connected to a bevel gear 205. The right side of the rotating rod 204 is fixedly connected to a flipping gear 206. The bevel gear 203 drives the flipping gear 206 to rotate through the bevel gear 204 and the rotating rod 205. The outer wall of the rocker arm 202 is fixedly connected to a rubber sleeve 15. The rubber sleeve 15 has anti-slip texture 16 on its outer surface. The rubber sleeve 15 and the anti-slip texture 16 can improve the anti-slip performance of the rocker arm 202.

[0042] Specifically, the connecting rod 201 is rotated by shaking the rocker arm 202. When the connecting rod 201 rotates, the bevel gear 203 fixed on it will also rotate synchronously. At the same time, the bevel gear 203 will drive the bevel gear 205 to rotate together through meshing. As the bevel gear 205 rotates, the rotating rod 204 fixed on its left side will also rotate together. When the rotating rod 204 rotates, the flipping gear 206 fixed on it will also rotate together. When the flipping gear 206 rotates, it can drive the fixed clamping wheel 4 to rotate through meshing. When the fixed clamping wheel 4 rotates, it will drive the clamping wheel 6 to rotate together through the threaded rod 7 fixed on it. This achieves the effect of flipping the clamped product. The rubber sleeve 15 fixed on the outside of the rocker arm 202 improves the anti-slip performance of the rocker arm 202 through its anti-slip texture 16, so that the user can grip it.

[0043] Reference Figure 1 and Figure 2 The top of the frame 1 is equipped with a top rail 17, and screws 18 are threaded to the four corners of the top of the top rail 17. The top rail 17 is a flip-up clamp that provides top protection. The lower right side of the inner side of the frame 1 is fixedly connected to a workbench 19. Support columns 20 are fixedly connected to the front and rear ends of the bottom left side of the workbench 19. The workbench 19 is used to place products. The rear side of the frame 1 is equipped with an X-shaped frame 21, and screws 22 are threaded to the four corners of the X-shaped frame 21. The X-shaped frame 21 can improve the stability of the frame 1.

[0044] Specifically, the top rail 17, which is fixed to the frame 1 by screw 18, provides effective protection for the top of the flip-up clamp, while the worktable 19, supported by the frame 1 and the support column 20, can place the product to be clamped, and the X-shaped frame 21, which is fixed to the back of the frame 1 by screw 22, can effectively improve the stability of the frame 1.

[0045] Working principle: When using the flip-up clamp to fix items, firstly, turning any one of the handles 10 drives any one of the sprockets 8 to rotate. At this time, this sprocket 8 will drive the other sprocket 8 to rotate synchronously through the chain 9. When the two sprockets 8 rotate, the two threaded rods 7 fixed on the right side will also be driven to rotate synchronously. At this time, the two threaded rods 7 will drive the clamping wheel 6 fixed to the left side of the frame 1 through the support rod 5 to move to the right. As the clamping wheel 6 moves to the right, the distance between it and the fixed clamping wheel 4 fixed to the right side of the frame 1 through the fixing column 3 is continuously reduced, thereby achieving the clamping effect on the product. At the same time, the hollow design of the fixed clamping wheel 4 and the clamping wheel 6 reduces the contact area between the fixed clamping wheel 4 and the clamping wheel 6 when clamping the product, thereby reducing the number of times it is necessary to put down and pick up during painting and coating, thus improving work progress and product quality.

[0046] When the flip-over clamp holds the product and needs to be flipped, the rocker arm 202 is turned to rotate the connecting rod 201. When the connecting rod 201 rotates, the bevel gear 203 fixed on it will also rotate synchronously. At the same time, the bevel gear 203 will drive the bevel gear 205 to rotate together through meshing. As the bevel gear 205 rotates, the rotating rod 204 fixed on its left side will also rotate together. When the rotating rod 204 rotates, the flip-over gear 206 fixed on it will also rotate together. When the flip-over gear 206 rotates, it can drive the fixed clamping wheel 4 to rotate through meshing. When the fixed clamping wheel 4 rotates, it will drive the clamping wheel 6 to rotate together through the threaded rod 7 fixed on it, thereby achieving the effect of flipping the clamped product.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
