Description

Technical Field

[0001] This utility model relates to the field of cylinder head processing technology, specifically a small-stroke lifting mechanism for processing cylinder heads. Background Technology

[0002] When machining cylinder blocks, if there is a distance restriction between the bottom surface of the workpiece and the worktable of the machining equipment (when the distance is small), and the workpiece needs to be lifted a small distance before positioning to avoid interference, the space required by the traditional lifting mechanism is too large and difficult to achieve in a limited environment.

[0003] As disclosed in CN214560707U, a short-stroke lifting mechanism for machining cylinder blocks uses a rotating assembly to move two movable rods on both sides. During movement, the upper and lower inclined surfaces work together to move the mandrel up and down. This design allows for short-stroke lifting of the cylinder block within a limited space, improving machining efficiency, and the movable rods enable synchronous lifting of the mandrel.

[0004] However, during use, the device drives the moving rods on both sides to move through the rotating component. When the moving rods move, the upper and lower inclined surfaces cooperate to move the top head up and down. However, excessive friction is generated between the upper and lower inclined surfaces, which increases the load on the rotating machine and causes the top head to jerk, affecting the stability of lifting.

[0005] Therefore, we urgently need to provide a small-stroke lifting mechanism for machining cylinder heads. Utility Model Content

[0006] The purpose of this invention is to provide a short-stroke lifting mechanism for machining cylinder heads, so as to solve the problem of low lifting stability mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a small-stroke lifting mechanism for machining cylinder heads, comprising a base plate, a support rod, and a platform. The support rod is fixedly installed around the top of the base plate, and the platform is fixedly installed on the top of the support rod. A lifting device is provided on the top of the base plate, and the lifting device includes a lifting mechanism and a clamping mechanism.

[0008] The lifting mechanism is located on the top of the base plate, and the clamping mechanism is located on the top of the platform.

[0009] The lifting mechanism includes a telescopic component one, a bracket, an inclined block, a push plate, a roller one, a lower guide rod, an upper guide rod, a top head, and a roller two. The telescopic component one is fixedly installed on the top back of the base plate. The bracket is installed at the output end of the telescopic component one. The inclined block is installed on the left and right sides of the top of the base plate. One end of the push plate is rotatably connected to one side of the two adjacent inclined blocks. The roller one is fixedly installed at the bottom of the inclined block. The lower guide rod is fixedly installed on the left and right sides of the top of the base plate. The upper guide rod is slidably installed inside the lower guide rod. The top head is fixedly installed at the top of the upper guide rod. The roller two is fixedly installed at the bottom of the top head.

[0010] Preferably, the end of the push plate away from the inclined block is rotatably connected inside the bracket, and a groove is provided on the upper surface of the base plate. The lower end of the roller is rotatably connected in the groove. By activating the telescopic component, the push plate is pushed to move. While the push plate rotates around the two inclined blocks on the left and right, it cooperates with the groove to limit the roller, so that the inclined block moves in a straight line along the groove. The roller reduces the friction between the inclined block and the surface of the base plate, making the movement of the inclined block smoother.

[0011] Preferably, the lower guide rod has an installation groove with the same diameter as the upper guide rod, and the upper surface of the platform has rectangular grooves on the left and right sides, the size of which is the same as the size of the top head. When the top head moves up and down, the upper guide rod slides along the installation groove of the lower guide rod, which limits the top head and prevents it from deviating.

[0012] Preferably, the upper surface of the inclined block is an inclined plane, and the bottom of the second roller contacts the inclined plane and rolls along the inclined plane. While the inclined block moves in a straight line, it pushes the second roller to roll along the inclined plane, thereby pushing the top head to rise and fall in a small stroke. At the same time, the second roller can reduce the friction force on the top head during the rise and fall, making the rise and fall of the top head more stable.

[0013] Preferably, a rubber pad is installed on the upper surface of the top end to prevent scratches on the cylinder head surface when the top end contacts the cylinder head.

[0014] Preferably, the clamping mechanism includes a telescopic component two and a clamping plate. The telescopic component two is fixedly installed on the front and rear sides of the top of the platform, and the clamping plate is fixedly installed on the output end of the telescopic component two.

[0015] Preferably, a rubber pad is installed on one side of the two adjacent clamping plates to prevent scratches on the cylinder head surface when the clamping plates are clamped, thus affecting the cylinder head processing quality.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. The cylinder head is processed using a small-stroke lifting mechanism. By setting up a lifting mechanism, the first telescopic component pushes the push plate to drive the inclined block to move linearly along the slide. At the same time as the inclined block moves linearly, the second roller is pushed to roll along the inclined surface, thereby driving the left and right tops to lift synchronously, making the lifting more stable and smooth.

[0017] 2. The cylinder head is processed using a small-stroke lifting mechanism. By setting up a clamping mechanism, the clamping plate is pushed by the activation of the telescopic component to clamp the two sides of the cylinder head. The clamping is convenient and efficient.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example

[0021] Due to the current issue of low stability in lifting and lowering technology, please refer to [link / reference]. Figures 1-4 The embodiment provides a short-stroke lifting mechanism for machining cylinder heads, which can achieve short-stroke lifting and improve lifting stability. The short-stroke lifting mechanism for machining cylinder heads includes a base plate 1, a support rod 2, and a platform 3. The support rod 2 is fixedly installed around the top of the base plate 1, and the platform 3 is fixedly installed on the top of the support rod 2. A lifting device is provided on the top of the base plate 1, which includes a lifting mechanism and a clamping mechanism.

[0022] The lifting mechanism is located at the top of the base plate 1, and the clamping mechanism is located at the top of the platform 3.

[0023] The lifting mechanism includes a telescopic component 401, a bracket 402, an inclined block 403, a push plate 404, a roller 405, a lower guide rod 406, an upper guide rod 407, a top head 408, and a roller 409. The telescopic component 401 is fixedly installed on the top back of the base plate 1. The telescopic component 401 includes a hydraulic cylinder and a hydraulic rod. The hydraulic cylinder is fixedly installed on the top back of the base plate 1, and the hydraulic rod is installed at the output end of the hydraulic cylinder. The bracket 402 is installed at the output end of the telescopic component 401. The inclined block 403 is installed on the left and right sides of the top of the base plate 1. The upper surface of the inclined block 403 is inclined, and the roller 409... 09 The bottom contacts the inclined plane and rolls along the inclined plane. While the inclined block 403 moves linearly, it pushes the roller 409 to roll along the inclined plane, thereby pushing the top head 408 to rise and fall in a small stroke. At the same time, the roller 409 can reduce the friction force on the top head 408 during the rise and fall, making the rise and fall of the top head 408 more stable. One end of the push plate 404 is rotatably connected to the adjacent side of the two inclined blocks 403. The end of the push plate 404 away from the inclined block 403 is rotatably connected to the inside of the bracket 402. The upper surface of the bottom plate 1 is provided with a sliding groove. The lower end of the roller 405 is rolled in the sliding groove. By starting the extension and retraction... Part 401 pushes the push plate 404 to move. The push plate 404 rotates around the two inclined blocks 403 while simultaneously limiting the roller 405 along the slide groove, causing the inclined blocks 403 to move linearly along the slide groove. The roller 405 reduces the friction between the inclined blocks 403 and the surface of the base plate 1, making the movement of the inclined blocks 403 smoother. The roller 405 is fixedly installed at the bottom of the inclined blocks 403. The lower guide rod 406 is fixedly installed on the top left and right sides of the base plate 1. The lower guide rod 406 has an installation groove with the same diameter as the upper guide rod 407 inside. Rectangular grooves are formed on the left and right sides of the upper surface of the platform 3. The upper guide rod 407 slides along the mounting groove of the lower guide rod 406 when the upper guide rod 407 moves up and down, thus limiting the movement of the upper guide rod 408 and preventing it from shifting. The upper guide rod 407 is slidably installed inside the lower guide rod 406, and the upper guide rod 408 is fixedly installed on the top of the upper guide rod 407. A rubber pad is installed on the upper surface of the upper guide rod 408 to prevent scratches on the cylinder head surface when the upper guide rod 408 contacts the cylinder head. The roller 409 is fixedly installed at the bottom of the upper guide rod 408. Example

[0024] Based on Example 1, please refer to Figures 1-4 In order to achieve rapid clamping of the cylinder head and improve the processing efficiency of the cylinder head, this device is also equipped with a clamping mechanism. The clamping mechanism includes a telescopic component 501 and a clamping plate 502. The telescopic component 501 is fixedly installed on the front and rear sides of the top of the platform 3. The telescopic component 501 is an electric push rod. The clamping plate 502 is fixedly installed on the output end of the telescopic component 501. Rubber pads are installed on the adjacent side of the two clamping plates 502. The rubber pads prevent the clamping plates 502 from scratching the surface of the cylinder head when clamping the cylinder head, thus affecting the processing quality of the cylinder head.

[0025] In use, by activating the telescopic component 401, the push plate 404 is moved. The push plate 404 rotates around the two inclined blocks 403 on the left and right sides, while cooperating with the slide groove to limit the roller 405, so that the inclined block 403 moves in a straight line along the slide groove. While the inclined block 403 moves in a straight line, it pushes the roller 409 to roll along the inclined surface, thereby pushing the top head 408 to rise and fall along the lower guide rod 406 through the upper guide rod 407, thus realizing the synchronous rise and fall of the two top heads 408 on the left and right sides, making the rise and fall more stable and smooth.
