[0018] Please see Figures 1-4The present invention provides the following technical solution: a hydraulic lock body 1, a clearance hole 11 is provided on the hydraulic lock body 1, a mounting bracket 2 is slidably connected to the clearance hole 11, a sliding plate 21 is slidably connected to the inner wall of the mounting bracket 2, a mounting plate 3 corresponding to the sliding plate 21 is fixedly connected to one side of the hydraulic lock body 1, an adjusting rod 31 is rotatably connected between the mounting plates 3, the adjusting rod 31 is threadedly connected to the sliding plate 21, a vertical rod 22 is installed at one end of the mounting bracket 2, a slip ring 23 is slidably connected to the outer wall of the vertical rod 22, a mounting ring 24 is slidably connected to the outer wall of the slip ring 23, a fixing rod 4 is fixedly connected to the outer wall of the mounting ring 24, side plates 41 are provided on both sides of the fixing rod 4, a support plate 46 is slidably connected between the fixing rod 4 and the side plates 41, a guide groove 431 is provided on the side plate 41, and an arc-shaped block 43 is slidably connected to the guide groove 431.
[0019] In this implementation scheme: the hydraulic lock body 1 is used to clamp the workpiece that needs to be clamped for processing. When clamping a hollow workpiece, the mounting bracket 2 can be installed through the clearance hole 11 on the hydraulic lock body 1. The height of the sliding plate 21 slidably connected to the inner wall of the mounting bracket 2 can be adjusted. The adjusting rod 31 rotatably connected to the mounting plate 3 can be threadedly connected to the sliding plate 21. When the adjusting rod 31 rotates, it can drive the sliding plate 21 and the mounting bracket 2 to adjust their positions, so that the height of the upright rod 22 fixedly connected to the mounting bracket 2 can be adjusted synchronously. The slip ring 23 installed on the outer wall of the upright rod 22 can be adjusted to make it easy to adjust the mounting ring 24 to a position corresponding to the horizontal position of the hollow workpiece. At this time, the fixing rod 4 fixedly connected to the outer wall of the mounting ring 24 can correspond to the hollow position of the workpiece, so that the mounting bracket 2 slides on the sliding plate 21 and slides in the clearance hole 11, so that the position of the fixing rod 4 can be adjusted to the hollow position of the hollow workpiece. At this time, the distance between the side plates 41 installed on both sides of the fixing rod 4 and the fixing rod 4 can be adjusted, so that the side plates 41 can slide on both sides of the fixing rod 4. When it is necessary to push the fixing rod 4 and the side plate 41 into the hollow part, the side plate 41 can be made to fit against the fixing rod 4, making it easy to push the fixing rod 4 and the side plate 41 into the hollow part. After pushing, the distance between the side plate 41 and the fixing rod 4 can be adjusted. By selecting a support plate 46 of different sizes according to the size of the hollow part, the support plate 46 can be installed between the fixing rod 4 and the side plate 41, allowing the support plate 46 to slide between the fixing rod 4 and the side plate 41, and the side plate 41 can be slid to the position of the hollow part. The position where the inner wall of the part is in contact with the part allows the device to support the inner wall of the hollow part. When it is necessary to clamp a cylindrical hollow part, the contact area between the clamping part and the workpiece is small. At this time, the arc block 43 can slide on the outside of the side plate 41, and the arc block 43 can slide to the position corresponding to the cylindrical hollow part, so that the clamping position of the clamping part can be supported by the arc block 43, thereby ensuring the protection of the hollow part. At the same time, when clamping the inner wall of a square hollow part, the arc block 43 can slide to make it misaligned, thereby protecting the square hollow part.
[0020] The top of the adjusting rod 31 passes through the mounting plate 3, and an adjusting ring 32 is installed on the top of the adjusting rod 31. The top of the adjusting rod 31 passes through the mounting plate 3, so that the adjusting ring 32 fixedly connected to the top of the mounting plate 3 can easily rotate the adjusting rod 31, thereby adjusting the height of the sliding plate 21 and thus adjusting the height of the mounting frame 2.
[0021] A slot 211 is provided at the connection between the mounting bracket 2 and the slide plate 21. Limiting blocks 212 that match the slot 211 are fixedly connected to both ends of the slide plate 21. When the mounting bracket 2 and the slide plate 21 are connected, the slot 211 and the limiting blocks 212 are connected and limited, so that the slide plate 21 can provide height support for the mounting bracket 2, and the mounting bracket 2 can slide on the slide plate 21 for position adjustment.
[0022] Two connecting rods 47 are installed on the fixed rod 4. The connecting rods 47 are slidably connected to the side plate 41. A spring 471 is sleeved on the outer wall of the connecting rod 47. The connecting rods 47 are used to limit the two ends of the fixed rod 4. The side plate 41 is supported by the spring 471, so that the side plate 41 can be supported by the spring 471 and fit against the fixed rod 4. This makes it easier for the fixed rod 4 and the side plate 41 to be pushed into the hollow part.
[0023] A sliding rod 42 is installed on the side plate 41. The sliding rod 42 is slidably connected to the fixed rod 4. One end of the sliding rod 42 is fixedly connected to a limiting plate 422. The fixed rod 4 has a limiting groove 421 that matches the limiting plate 422. The sliding rod 42 can connect the side plate 41 to the fixed rod 4. The limiting plate 422 fixedly connected to one end of the sliding rod 42 limits the side plate 41 within the limiting groove 421, thereby limiting the limiting groove 421 and the limiting plate 422, and thus allowing the position of the side plate 41 to be adjusted.
[0024] The fixed rod 4 has clearance grooves 44 on both sides, and support grooves 45 connected to the clearance grooves 44 on both sides. The support grooves 45 match the support plate 46. The clearance grooves 44 on both sides of the fixed rod 4 can install the support plate 46. The support plate 46 can be slidably limited in the support grooves 45, so that the support grooves 45 can be slidably supported between the side plate 41 and the fixed rod 4, thereby fixing the position of the side plate 41.
[0025] A push block 461 is fixedly connected to one end of the support plate 46. The support plate 46 matches the relief groove 44 and the support groove 45. A guide block 432 that matches the guide groove 431 is fixedly connected to the arc-shaped block 43. The push block 461 is used to facilitate pushing the support plate 46 so that the support plate 46 slides in the support groove 45, so that the support plate 46 supports one side of the side plate 41. The guide groove 431 matches the guide block 432 so that the arc-shaped block 43 can slide stably on one side of the side plate 41.
[0026] The working principle and usage process of this utility model are as follows: Select a suitable support plate 46 according to the size of the hollow workpiece, install the mounting bracket 2 into the clearance hole 11 of the hydraulic lock body 1, with the slide plate 21 in the initial position, rotate the adjusting ring 32 to drive the adjusting rod 31 to rotate. Since the adjusting rod 31 is threadedly connected to the slide plate 21, the slide plate 21 and the mounting bracket 2 are adjusted in height synchronously to allow the upright 22 to reach a suitable height. The slot 211 and the limit block 212 ensure stable connection. Install the mounting ring 24 on the outer wall of the upright 22, and use the slip ring 23 to finely adjust the position of the mounting ring 24 so that the fixed rod 4 is horizontally aligned with the hollow position of the hollow workpiece. Push the side plate 41 to stick to both sides of the fixed rod 4. The side plate 41 is then... The slide rod 42 is slidably connected to the fixed rod 4. The connecting rod 47 and the spring 471 provide auxiliary support for subsequent pushing. The adjusted fixed rod 4 and the side plates 41 that fit on both sides are pushed into the hollow part of the hollow workpiece. The selected support plate 46 is slid from the relief groove 44 of the fixed rod 4 into the support groove 45. The push block 461 pushes the support plate 46 so that it is supported between the side plate 41 and the fixed rod 4, so that the side plate 41 fits against the inner wall of the hollow workpiece. The arc block 43 is slid along the guide groove 431 of the side plate 41 to the corresponding position. The guide block 432 cooperates with the guide groove 431 to provide support for the clamping point. The sliding arc block 43 is misaligned to provide protection for the square hollow workpiece.
