[0002] A hydraulic clamp is a device that uses hydraulic oil as a transmission medium to generate and control a strong clamping force through a hydraulic system to fix workpieces in machining. Hydraulic clamps are commonly used, especially when machining valve body covers.

[0003] Traditional hydraulic clamps, when used to fix and limit the valve body cover, can only process one side of the valve body cover. Furthermore, excessive pressure when clamping and fixing the valve body cover may damage the internal structure of the valve body cover. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of existing technologies and solve the problems that traditional hydraulic clamps can only process one side of the valve body cover after clamping and limiting the workpiece, and that excessive pressure from the clamps may damage the internal structure of the valve body cover. A hydraulic clamp for the valve body cover is designed.

[0005] To achieve the above objectives, this application provides the following technical solution: A hydraulic clamp for a valve body cover includes a hydraulic clamp body and a control mechanism located inside the hydraulic clamp body. The hydraulic clamp body includes a support base plate, and support vertical plates are fixedly connected to both sides of the support base plate. The left side of the left support vertical plate is fixedly connected to the output end of a first motor, and a hydraulic pump is installed inside the right support vertical plate. The control mechanism includes several connecting blocks, each of which is slidably connected inside the support base plate. The bottom of each connecting block is fixedly connected to the output end of the hydraulic cylinder. The hydraulic pump is used to control the hydraulic cylinder.

[0006] Preferably, the support base plate has a plurality of placement slots inside, and each placement slot has a positioning post at one of its four corners, and the positioning post is fixedly connected to the support base plate.

[0007] Preferably, the top of the hydraulic clamp body is provided with a plurality of valve body covers, each valve body cover including a cover body, and positioning holes are provided at the four corners of the top of the cover body. The positioning holes are adapted to the positioning pins, and a placement block is fixedly connected to the bottom of the cover body. The placement block is adapted to the placement groove.

[0008] Preferably, each of the connecting blocks has a movable gear ring movably connected to its center, a movable gear meshing with the front of each movable gear ring, the bottom of each movable gear being fixedly connected to the output end of the second motor, a rotating rod being fixedly connected inside each movable gear ring, and each rotating rod extending upwards out of the top of the supporting base plate.

[0009] Preferably, a limiting mechanism is provided at the top of the control mechanism. The limiting mechanism includes several pressure plates, which are divided into half pressure plates and full pressure plates. Each pressure plate is fixedly connected to the top of several rotating rods.

[0010] Preferably, each of the pressure plates has a support slide rod fixedly connected to both the front and rear sides of its bottom. Each support slide rod has a sliding block sleeved on its outside. A buffer spring is connected to one side of each of the two sliding blocks facing each other.

[0012] Compared with the prior art, this application provides a hydraulic clamp for a valve body cover, which has the following advantages: 1. This application solves the problem that traditional hydraulic clamps can only process one side of the valve body cover after clamping and limiting the workpiece. By aligning the placement block at the bottom of the valve body cover with the placement groove and inserting it, the hydraulic pump controls the hydraulic cylinder to pull the limiting mechanism to limit and fix the valve body cover. The first motor controls the rotation of the main body of the hydraulic clamp, which enables the machining of two opposite sides of the cover in CNC. The second motor controls the rotation of the rotating rod to adjust the direction of the pressure plate, so that the valve body cover can be squeezed and fixed.

[0013] 2.

Detailed Implementation

[0016] Please see Figures 1-4 A hydraulic clamp for valve body cover shells includes a hydraulic clamp body 1 and a control mechanism 3 located inside the hydraulic clamp body 1. Several valve body cover shells 2 are provided on the top of the hydraulic clamp body 1, and a limit mechanism 4 is provided on the top of the control mechanism 3.

[0017] like Figures 1-4 As shown, the hydraulic clamp body 1 includes a support base plate 101, with support vertical plates 102 fixedly connected to both sides of the support base plate 101. The left side of the left support vertical plate 102 is fixedly connected to the output end of the first motor 105, and a hydraulic pump is installed inside the right support vertical plate 102. The control mechanism 3 includes several connecting blocks 301, each of which is slidably connected inside the support base plate 101. The bottom of each connecting block 301 is fixedly connected to the output end of the hydraulic cylinder 306. The hydraulic pump is used to control the hydraulic cylinder 306. The plate 101 has several placement slots 103 inside, and each placement slot 103 has a positioning post 104 at each of its four corners. The positioning post 104 is fixedly connected to the support base plate 101. The top of the hydraulic clamp body 1 has several valve body cover shells 2. Each valve body cover shell 2 includes a cover shell body 201. The top four corners of the cover shell body 201 are provided with positioning holes 202. The positioning holes 202 are adapted to the positioning posts 104. The bottom of the cover shell body 201 is fixedly connected with a placement block 203, which is adapted to the placement slot 103.

[0018] The above scheme involves aligning the placement block 203 at the bottom of the valve body cover 2 with the placement groove 103 and inserting it. The hydraulic cylinder 306 is started by the hydraulic pump, which pulls the limiting mechanism 4 to limit and fix the valve body cover 2. The first motor 105 is started, which allows the hydraulic fixture body 1 to rotate. In CNC, the two opposite sides of the housing can be machined.

[0019] like Figure 1 , Figure 2 and Figure 4 As shown, each connecting block 301 has a movable gear ring 302 movably connected to its center, and each movable gear ring 302 has a movable gear 303 meshing with its front. The bottom of each movable gear 303 is fixedly connected to the output end of the second motor 304. Each movable gear ring 302 has a rotating rod 305 fixedly connected inside, and each rotating rod 305 extends upward out of the top of the supporting base plate 101.

[0020] Through the above scheme: the second motor 304 starts, driving the movable gear 303 to rotate. Under the meshing action of the movable gear 303 and the movable gear ring 302, the movable gear ring 302 drives the rotating rod 305 to rotate, completing the adjustment of the direction of the pressure plate 401, so that it can squeeze and fix the valve body cover 2.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, the limiting mechanism 4 includes several pressure plates 401, which are divided into half-pressure plates and full-pressure plates. Each pressure plate 401 is fixedly connected to the top of several rotating rods 305. Supporting slide rods 402 are fixedly connected to the front and rear sides of the bottom of each full-pressure plate. Sliding blocks 403 are sleeved on the outside of each supporting slide rod 402. Buffer springs 404 are connected to the opposing sides of two sliding blocks 403. The sliding blocks 403 are elastically connected to the full-pressure plate through the buffer springs 404. A movable rod 405 is movably pinned to the bottom of each sliding block 403. The two movable rods 405... A uniform buffer plate 406 is connected to the bottom movable pin. The buffer plate 406 is slidably connected to the rotating rod 305. A support slide rod 402 is fixedly connected to the rear side of each half plate. A sliding block 403 is sleeved on the outside of each support slide rod 402. A buffer spring 404 is connected to the rear of each sliding block 403. The sliding block 403 is elastically connected to the half plate through the buffer spring 404. A movable rod 405 is connected to the bottom movable pin of the sliding block 403. Another buffer plate 406 is connected to the bottom movable pin of the movable rod 405. The other buffer plate 406 is slidably connected to the rotating rod 305.

[0022] Through the above scheme: during the limiting and fixing process, the buffer plate 406 moves down, and under the action of the movable rod 405, the sliding block 403 moves laterally along the support sliding rod 402, squeezing the buffer spring 404 to generate elastic potential energy, which is used to offset part of the pressure generated by the downward pressure of the pressure plate 401, and plays a protective role for the valve body cover 2.

[0023] Working principle: In actual use, firstly, the placement block 203 at the bottom of the valve body cover 2 is aligned with the placement groove 103 and inserted. The hydraulic cylinder 306 is controlled by the hydraulic pump to pull the limiting mechanism 4 to limit and fix the valve body cover 2. The hydraulic fixture body 1 is rotated by the first motor 105. The two opposite sides of the housing can be machined in CNC.

[0024] Secondly, the second motor 304 drives the movable gear 303 to rotate, and the movable gear 303 meshes with the movable gear ring 302, causing the movable gear ring 302 to drive the rotating rod 305 to rotate, thereby adjusting the direction of the pressure plate 401 so that it can press and fix the valve body cover 2.

[0025] Finally, during the limiting and fixing process, the buffer plate 406 moves down, causing the sliding block 403 to move laterally along the support slide rod 402, squeezing the buffer spring 404 to generate elastic potential energy, which is used to offset part of the pressure generated by the downward pressure of the pressure plate 401, thus protecting the valve body cover 2.
