Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder processing technology, and more specifically, to a support frame for hydraulic cylinder processing. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. During the production of hydraulic cylinders, a support frame is usually used to provide support and fixation for the hydraulic cylinder, ensuring its stability during processing.

[0003] Chinese patent publication CN202323272956.0, entitled "A Support Frame for Hydraulic Cylinder Machining," describes a support frame for hydraulic cylinder machining, relating to the field of hydraulic cylinder machining technology. The support frame includes a base, a support rod fixedly connected to the top of the base by bolts, a lower clamp fixedly connected to the top of the support rod, a guide rod fixedly connected to the top of the lower clamp, an upper clamp slidably connected to the outer wall of the guide rod, a connecting plate fixedly connected to the outer wall of the guide rod, a concave plate fixedly connected to the connecting plate, a housing slidably connected to the concave plate, a threaded rod threadedly connected to the inner wall of the housing, and a bottom of the threaded rod rotatably connected to the top of the upper clamp. This utility model incorporates a housing and a concave plate, enabling... The pressing method quickly moves the housing downwards, causing the upper clamp to clamp and fix the outer wall of the hydraulic cylinder. The spring and wedge block, in conjunction with this, limit the vertical position of the housing, ensuring stability after the upper clamp is pressed and fixed. However, a problem remains: when using this support frame, if the position of the upper furniture needs to be adjusted upwards, the user must pull the levers. Since there are two levers symmetrically distributed on both sides of the housing, the user must use both hands to pull the levers at two different positions simultaneously. A second person is also needed to control the position of the housing, making it impossible for one person to operate independently. This reduces ease of use and increases labor costs. Therefore, we provide a support frame for hydraulic cylinder processing. Utility Model Content

[0004] The purpose of this utility model is to provide a support frame for machining hydraulic cylinders, so as to solve the problems mentioned in the background art.

[0005] Some existing support frames require users to pull the levers to adjust the position of the upper clamp upwards. Since there are two levers symmetrically distributed on both sides of the housing, users need to pull the levers at two different positions with both hands at the same time. Then, a second person is needed to control the position of the housing separately, making it impossible for one person to operate alone. This reduces the convenience of use and increases labor costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A support frame for machining hydraulic cylinders includes a base. A lower clamp is mounted on the top of the base. A guide rod is fixedly connected to the top of the lower clamp. An upper clamp is slidably connected to the outside of the guide rod. A connecting plate is fixedly connected to the top of the guide rod. A movable block is slidably connected inside the connecting plate. First grooves are formed on corresponding sides of the movable block. A locking block is slidably connected inside the first groove. An inclined groove is formed inside the locking block. A horizontal bar is slidably connected inside the inclined groove. A vertical bar is fixedly connected to the outside of the horizontal bar. The vertical bar is slidably connected to the movable block. The vertical bar moves up and down... During movement, the horizontal bar can press against the inclined groove, thereby moving the locking block. A ring plate is fixedly connected to the top of the vertical bar, and a knob is rotatably connected inside the ring plate. A second groove is formed inside the knob, and a slider is slidably connected inside the second groove. A first threaded rod is fixedly connected to the bottom of the slider, and the first threaded rod is threadedly connected to the movable block. The upper clamp is rotatably connected to the first threaded rod. A fixed plate is fixedly connected inside the connecting plate, and a locking groove is formed inside the fixed plate. The locking groove cooperates with the locking block. Multiple locking grooves are arranged vertically on the fixed plate.

[0008] Preferably, the outer side of the locking block away from the vertical rod is chamfered, so that when the user adjusts the movable block downwards, there is no need to push or pull the annular plate upwards.

[0009] Preferably, the cross-sections of the first groove, the locking block, the second groove, and the slider are all square structures. The outer wall of the locking block is in contact with the inner wall of the first groove, and the outer wall of the slider is in contact with the inner wall of the second groove. Since the cross-sections of the first groove and the locking block are square structures, the locking block can only move linearly inside the first groove. The cross-sections of the second groove and the slider are square structures, so that when the knob is rotated, the knob can drive the first threaded rod to rotate through the second groove and the slider.

[0010] Preferably, a spring is provided between the first groove and the locking block. One end of the spring is fixedly connected to the movable block, and the other end of the spring is fixedly connected to the locking block. The elastic force of the spring can drive the locking block in the first groove to automatically engage with the slot on the fixed plate.

[0011] Preferably, an annular limiting groove is provided inside the knob and below the annular plate. An annular limiting plate is slidably connected inside the annular limiting groove. A sleeve is fitted outside the knob between the annular limiting plate and the movable block. One end of the sleeve is fixedly connected to the annular limiting plate, and the other end of the sleeve is fixedly connected to the movable block. The sleeve on the movable block uses the annular limiting plate and the annular limiting groove to limit the knob. Under the action of the annular limiting plate and the annular limiting groove, the knob can rotate more smoothly. When the knob rotates, the knob can drive the first threaded rod to rotate through the second groove and the slider. The first threaded rod then drives the upper clamp to move up and down.

[0012] Preferably, the base has an internal groove, and a second threaded rod is rotatably connected inside the groove. An adjusting block is sleeved on the outside of the second threaded rod, and the adjusting block is threadedly connected to the second threaded rod. The outer side wall of the adjusting block fits against the inner side wall of the groove, and the adjusting block is slidably connected to the base. One of the lower clamps is fixedly connected to the adjusting block. When the user rotates the second threaded rod, the second threaded rod can drive the adjusting block to move back and forth in the groove on the base, so that the adjusting block can adjust the position of one set of lower clamps and upper clamps to accommodate hydraulic cylinders of different lengths.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) When using the support frame for hydraulic cylinder machining, pull up the annular plate. The annular plate, through the vertical rod, drives the horizontal rod to press against the inner wall of the inclined groove, thereby pushing the locking block into the first groove until the locking block separates from the slot on the fixed plate. At this time, the user can directly adjust the position of the movable block and the upper clamp. After releasing the hand, due to the elastic force of the spring, the locking block automatically extends out of the first groove and engages with the corresponding slot. Then, turn the knob. The knob drives the first threaded rod to rotate through the second groove and the slider, so that the first threaded rod drives the upper clamp to move up and down. Together with the lower clamp, it supports and fixes the hydraulic cylinder. The operation of the locking block and the operation of the first threaded rod are set together. Moreover, the user only needs to pull up the annular plate to control the simultaneous movement of the two locking blocks in different positions, which is conducive to one-handed operation by the user. This not only improves the convenience of operation, but also reduces labor costs.

[0015] 2) When using the support frame for hydraulic cylinder processing, the second threaded rod on the base is screwed, which causes the adjusting block inside the slide groove to move. The adjusting block then moves one of the lower clamps, thereby adjusting the distance between the two sets of lower clamps and the upper clamp. This allows the support frame to support and fix hydraulic cylinders of different lengths, increasing the applicability of the support frame and bringing convenience to the production and processing of hydraulic cylinders.

[0021] Example 1

[0022] When using some existing support frames, if the position of the upper clamp needs to be adjusted upwards, the user has to pull the lever. Since there are two levers, which are symmetrically distributed on both sides of the housing, the user needs to pull the levers at two different positions with both hands at the same time. Then a second person is needed to control the position of the housing separately, which makes it impossible for one person to operate alone, thereby reducing the convenience of use and increasing labor costs.

[0023] Please see Figures 1 to 4A support frame for machining hydraulic cylinders includes a base 1. A lower clamp 2 is provided on the top of the base 1. A guide rod 3 is fixedly connected to the top of the lower clamp 2. An upper clamp 4 is slidably connected to the outside of the guide rod 3. A connecting plate 5 is fixedly connected to the top of the guide rod 3. A movable block 6 is slidably connected inside the connecting plate 5. A first groove 7 is provided on each of the corresponding two sides of the movable block 6. A locking block 8 is slidably connected inside the first groove 7. A slanted groove 9 is provided inside the locking block 8. A horizontal bar 10 is slidably connected inside the slanted groove 9. A vertical bar 11 is fixedly connected to the outside of the horizontal bar 10. The vertical bar 11 is slidably connected to the movable block 6. When the vertical bar 11 moves up and down, it can squeeze the slanted groove 9 through the horizontal bar 10, thereby driving the locking block 8 to move. A ring plate 12 is fixedly connected to the top of the vertical rod 11. A knob 13 is rotatably connected inside the ring plate 12. A second groove 14 is opened inside the knob 13. A slider 15 is slidably connected inside the second groove 14. A first threaded rod 16 is fixedly connected to the bottom of the slider 15. The first threaded rod 16 is threadedly connected to the movable block 6. The upper clamp 4 is rotatably connected to the first threaded rod 16. A fixed plate 17 is fixedly connected inside the connecting plate 5. A slot 18 is opened inside the fixed plate 17. The slot 18 is used in conjunction with the locking block 8. Multiple slots 18 are provided on the fixed plate 17 and are distributed vertically. The position of the upper clamp 4 can be quickly adjusted by using the locking block 8 and the slot 18 without having to constantly turn the knob 13.

[0024] Furthermore, a chamfer 19 is provided on the outer side of the locking block 8 away from the vertical rod 11. Under the action of the chamfer 19, when the user adjusts the movable block 6 downward, there is no need to push or pull the annular plate 12 upward. The chamfer 19 can press the locking block 8 into the first groove 7 through its inclined surface.

[0025] Furthermore, the cross-sections of the first groove 7, the locking block 8, the second groove 14, and the slider 15 are all square structures. The outer wall of the locking block 8 fits against the inner wall of the first groove 7, and the outer wall of the slider 15 fits against the inner wall of the second groove 14. Since the cross-sections of the first groove 7 and the locking block 8 are square structures, the locking block 8 can only move linearly inside the first groove 7. The cross-sections of the second groove 14 and the slider 15 are square structures, so that when the knob 13 is rotated, the knob 13 can drive the first threaded rod 16 to rotate through the second groove 14 and the slider 15. When the first threaded rod 16 rotates, it can drive the upper clamp 4 to move up and down.

[0026] Furthermore, a spring 20 is provided between the first groove 7 and the locking block 8. One end of the spring 20 is fixedly connected to the movable block 6, and the other end of the spring 20 is fixedly connected to the locking block 8. The elastic force of the spring 20 can drive the locking block 8 in the first groove 7 to automatically engage with the locking groove 18 on the fixed plate 17, thereby limiting the position of the movable block 6 through the locking block 8 and the locking groove 18.

[0027] Furthermore, an annular limiting groove 21 is provided inside the knob 13 and below the annular plate 12. An annular limiting plate 22 is slidably connected inside the annular limiting groove 21. A sleeve 23 is sleeved outside the knob 13 and between the annular limiting plate 22 and the movable block 6. One end of the sleeve 23 is fixedly connected to the annular limiting plate 22, and the other end of the sleeve 23 is fixedly connected to the movable block 6. The sleeve 23 on the movable block 6 uses the annular limiting plate 22 and the annular limiting groove 21 to limit the knob 13. Under the action of the annular limiting plate 22 and the annular limiting groove 21, the knob 13 can rotate more smoothly. When the knob 13 rotates, the knob 13 can drive the first threaded rod 16 to rotate through the second groove 14 and the slider 15. The first threaded rod 16 then drives the upper clamp 4 to move up and down, thereby adjusting the distance between the upper clamp 4 and the lower clamp 2, so as to achieve the purpose of supporting and fixing the hydraulic cylinder.

[0028] The usage steps of this utility model are as follows: When using this support frame for hydraulic cylinder processing, if it is necessary to adjust the position of the upper clamp 4 upwards, the user only needs to pull the annular plate 12 on the outside of the knob 13 upwards. The annular plate 12 will drive the vertical rod 11 on the movable block 6 to move upwards, and the vertical rod 11 will then drive the horizontal rod 10 to move upwards as well. During this process, the horizontal rod 10 will push the locking block 8 into the first groove 7 by squeezing the inner wall of the inclined groove 9. At the same time, the locking block 8 will compress the spring 20 until the locking block 8 separates from the locking groove 18 on the fixed plate 17. At this time, the user can directly adjust the position of the movable block 6 and the upper clamp 4. After the user releases their hand... Due to the elastic force of the compressed spring 20, the locking block 8 automatically extends out of the first groove 7 and engages with the corresponding locking slot 18. Then, the knob 13 is turned, and the knob 13 drives the first threaded rod 16 to rotate through the second groove 14 and the slider 15. This causes the first threaded rod 16 to move the upper clamp 4 up and down, which, together with the lower clamp 2, supports and fixes the hydraulic cylinder. The operation of the locking block 8 and the operation of the first threaded rod 16 are set together. Moreover, the user only needs to pull the annular plate 12 upward to control the simultaneous movement of the two locking blocks 8 in different positions. This is beneficial for the user to operate with one hand, which not only improves the convenience of operation but also reduces labor costs.

[0029] Example 2

[0030] The two sets of lower clamps 2 and upper clamps 4 are set on the base 1. If the two lower clamps 2 are fixed together with the base 1, then the positions between the two sets of lower clamps 2 and upper clamps 4 are also fixed. This means that this connection method can only support a small number of hydraulic cylinders. When the hydraulic cylinder is short, it may not be compatible. The following solution solves this problem.

[0031] Please see Figures 1 to 4Based on implementation 1, the difference in this embodiment is that the base 1 has a sliding groove 24 inside, and a second threaded rod 25 is rotatably connected inside the sliding groove 24. An adjusting block 26 is sleeved on the outside of the second threaded rod 25. The adjusting block 26 is threadedly connected to the second threaded rod 25. The outer side wall of the adjusting block 26 fits against the inner side wall of the sliding groove 24. The adjusting block 26 is slidably connected to the base 1. One of the lower clamps 2 is fixedly connected to the adjusting block 26. When the user rotates the second threaded rod 25, the second threaded rod 25 can drive the adjusting block 26 to move back and forth in the sliding groove 24 on the base 1, so that the adjusting block 26 can adjust the position of one set of lower clamps 2 and upper clamps 4. By changing the distance between the two sets of lower clamps 2 and upper clamps 4, it can adapt to hydraulic cylinders of different lengths.

[0032] The usage steps of this utility model are as follows: When using this support frame for hydraulic cylinder processing, if the distance between the two sets of lower clamps 2 and upper clamps 4 is large, and the hydraulic cylinder to be supported is relatively short, the user can directly screw on the second threaded rod 25 on the base 1. When the second threaded rod 25 rotates, it will drive the adjusting block 26 inside the slide groove 24 to move. The adjusting block 26 will then drive one of the lower clamps 2 to move, thereby adjusting the distance between the two sets of lower clamps 2 and upper clamps 4. This allows the support frame to support and fix hydraulic cylinders of different lengths, increasing the applicability of the support frame and bringing convenience to the production and processing of hydraulic cylinders.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
