[0002] A fixture is a device used to fix the object to be processed during the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a clamp.

[0003] In a broad sense, any device used to quickly, conveniently and safely install a workpiece in any process can be called a fixture. A fixture usually consists of a positioning element (to determine the correct position of the workpiece in the fixture), a clamping device, a tool guide element (to determine the relative position of the tool and the workpiece or to guide the direction of the tool), an indexing device (to enable the workpiece to complete the processing of several stations in one installation, and there are two types of rotary indexing devices and linear moving indexing devices), connecting elements, and a clamp body (fixture base).

[0004] A hydraulic clamp is a clamp that uses hydraulic components instead of mechanical parts to achieve automatic positioning, support and clamping of the workpiece through hydraulic control. It has the advantages of large clamping force, reliable clamping, stable operation and easy use. It is widely used in machining centers, automated production lines and other scenarios. The hydraulic clamp includes a hydraulic mechanism and a clamp body, but the existing hydraulic clamp uses bolts to fix multiple components of the hydraulic clamp on the clamp body on mechanical equipment. During the manual installation process, the workpiece needs to be positioned and aligned before it can be fixed and installed. During the manual installation process, deviations are inevitable, resulting in poor alignment between the workpieces and inaccurate positioning during processing. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: comprising a base, a mounting plate arranged on the base, a fixed chuck arranged on one side of the top surface of the mounting plate, and a hydraulic press arranged on the other side of the top surface of the mounting plate, a mobile chuck is arranged between the fixed chuck and the hydraulic press, a telescopic rod of the hydraulic press is fixed to the mobile chuck, and also comprising a slide groove transversely opened on the top surface of the mounting plate, a second lock slider and a first slider are slidably arranged in the slide groove, the second lock slider is fixedly connected to the mobile chuck, and the first slider is fixedly connected to the fixed chuck;

[0007] A notch communicated with the slide groove is provided on one side of the mounting plate, and the hydraulic press is located in the notch.

[0008] It should be noted in the scheme that locking holes are provided on both sides of the mounting plate, and the locking holes are divided into two groups, one of which is connected to the slide groove, and the other is connected to the inside of the notch, and locking blocks are slidably arranged in both groups of locking holes, and fixing openings matching the locking blocks are provided on the side walls of the first sliding block and the hydraulic press.

[0009] It should be noted in the scheme that the fixed chuck is L-shaped, and a baffle is slidably arranged on the inner side of the fixed chuck, a buffer component is arranged between the baffle and the innermost inner wall of the fixed chuck, and a clamp block corresponding to the baffle is fixed on the side of the movable chuck away from the hydraulic press.

[0010] It is further worth explaining that the buffer assembly includes a moving rod vertically fixed on the side of the baffle facing away from the moving chuck, a mounting hole is opened on the inner wall of the fixed chuck, a spring is fixed on the innermost inner wall of the mounting hole, and the end of the moving rod is inserted into the mounting hole and fixed to the spring.

[0011] It should be noted in the solution that a stopper is also fixed on the top surface of the mounting plate, the stopper is triangular in shape, and the right-angled surface of the stopper is arranged on one side of the slide groove and abuts against the fixing clamp.

[0012] Compared with the prior art, the utility model provides a hydraulic clamp that is easy to install, which has at least the following beneficial effects:

[0013] (1) Through the setting of the slide groove, during the actual installation process, it is only necessary to install the fixed chuck with the first slider and the second slider at the bottom and the movable chuck into the slide groove through the first slider and the second slider, and then fix the hydraulic press on the mounting plate, and then fix the movable chuck to the output end of the hydraulic press, and the installation can be completed, which greatly reduces the difficulty of installation and improves the installation accuracy and installation time.

[0014] (2) By setting the fixed chuck and the buffer component, when clamping the workpiece, the workpiece is placed on the bottom plate of the fixed chuck, and the hydraulic press pushes the movable chuck to move toward the fixed chuck, so that the clamping block contacts the workpiece first, and the baffle and the clamping block clamp the workpiece first. When the hydraulic press pushes toward the fixed chuck, the baffle is displaced due to excessive pressure, and the movable rod on the baffle moves into the mounting hole and compresses the spring until the movable chuck contacts the bottom plate of the fixed chuck. At this time, the hydraulic press is unable to extend the telescopic rod due to resistance, and the workpiece can be stably fixed and effectively protected at the same time.

The installation process requires positioning and alignment operations before fixed installation. During the manual installation process, deviations are inevitable, resulting in poor alignment between workpieces and inaccurate positioning during processing.

[0024] Further, refer to Figure 1-4As shown, it is worth noting that it also includes a slide groove 10 transversely opened on the top surface of the mounting plate 2, and a second lock slider 12 and a first slider 9 are slidably arranged in the slide groove 10, the second lock slider 12 is fixedly connected to the movable chuck 4, and the first slider 9 is fixedly connected to the fixed chuck 3;

[0025] A notch is provided on one side of the mounting plate 2 and is connected to the slide groove 10, and the hydraulic press 5 is located in the notch;

[0026] Through the setting of the slide groove 10, during the actual installation process, it is only necessary to install the fixed chuck 3 and the movable chuck 4 with the first slider 9 and the locking second slider 12 at the bottom into the slide groove 10 through the first slider 9 and the locking second slider 12, and then fix the hydraulic press 5 on the mounting plate 2, and then fix the movable chuck 4 to the output end of the hydraulic press 5, and the installation can be completed, which greatly reduces the difficulty of installation and improves the installation accuracy and installation time.

[0027] Further, refer to Figure 1-3 As shown, it is worth noting that locking holes 11 are provided on both sides of the mounting plate 2, and the locking holes 11 are in two groups, one of which is connected to the slide groove 10, and the other is connected to the inside of the notch, and locking blocks 8 are slidably arranged in the two groups of locking holes 11, and the first sliding block 9 and the side wall of the hydraulic press 5 are provided with fixing openings adapted to the locking blocks 8;

[0028] Through the setting of the locking hole 11 and the locking block 8, when the fixed chuck 3 slides to the bottom end of the slide groove 10, the fixed chuck 3 is fixed by the locking block 8 passing through the locking hole 11 and the fixing port in the first slide block 9. When the hydraulic press 5 is moved to the specified position on the mounting plate 2, the two locking blocks 8 are passed through the locking holes 11 opened on both sides of the mounting plate 2, and then the locking blocks 8 are passed through the fixing ports on the hydraulic press 5, so that the hydraulic press 5 is fixed to the mounting plate 2, and the fixed chuck 3 and the hydraulic press 5 can be fixed conveniently and quickly.

[0029] In actual use, especially when the hydraulic press 5 is manually operated, the telescopic end of the hydraulic press 5 may be excessively extended, resulting in excessive squeezing force on the workpiece, causing deformation;

[0030] Further, refer to Figure 1-4 As shown, it is worth noting that the fixed chuck 3 is L-shaped, and a baffle 6 is slidably arranged on the inner side of the fixed chuck 3, a buffer assembly is arranged between the baffle 6 and the innermost inner wall of the fixed chuck 3, and a clamping block 7 corresponding to the baffle 6 is fixed on the side of the movable chuck 4 away from the hydraulic press 5;

[0032] By setting the fixed chuck 3 and the buffer component, when clamping the workpiece, the workpiece is placed on the bottom plate of the fixed chuck 3, and the hydraulic press 5 pushes the movable chuck 4 to move toward the fixed chuck 3, so that the clamp block 7 contacts the workpiece first, and the baffle 6 and the clamp block 7 clamp the workpiece first. When the hydraulic press 5 pushes toward the fixed chuck 3, the baffle 6 is displaced due to excessive pressure, and the movable rod 14 on the baffle 6 moves into the mounting hole 16 and compresses the spring 15 until the movable chuck 4 contacts the bottom plate of the fixed chuck 3. At this time, the hydraulic press 5 will not be able to extend the telescopic rod due to resistance, and the workpiece can be effectively protected while being stably fixed.

[0033] Further, refer to Figure 1-3 It is worth noting that a stopper 13 is also fixed on the top surface of the mounting plate 2. The stopper 13 is triangular in shape. The right-angle surface of the stopper 13 is arranged on one side of the slide groove 10 and abuts against the fixing chuck 3.

[0034] Through the setting of the stop block 13, when the movable chuck 4 and the fixed chuck 3 clamp the workpiece, only the first slider 9 at the bottom of the fixed chuck 3 is under pressure. The stop block 13 is set on one side of the fixed chuck 3 and the stop block 13 is abutted against the fixed chuck 3, which can effectively distribute the pressure evenly to the fixed chuck 3 and prevent the first slider 9 from being deformed.
