Description

Technical Field

[0001] The invention relates to the technical field of tooling fixtures, and in particular to a clamping device used for plunger milling flange surfaces. Background Art

[0002] In the field of mechanical processing, milling of the flange surface of the plunger is a common processing requirement. The plunger is a common mechanical component, widely used in hydraulic systems, pneumatic systems and other occasions that require sealing and pressure transmission. In these systems, the flange surface of the plunger needs to fit closely with other components, so there are high requirements for the flatness and accuracy of the flange surface. Traditional plunger milling usually adopts a single workpiece clamping method, that is, only one plunger flange surface can be processed at a time. This processing method is inefficient, and because it requires multiple clamping and positioning, the operation is complicated, which easily leads to a decrease in processing accuracy. Summary of the invention

[0003] The object of the present invention is to provide a clamping device for milling flange surfaces of plungers, so as to process a plurality of plungers at the same time and reduce the complexity of operation, thereby improving the processing efficiency.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a clamping device for plunger milling flange surface, comprising a base, a positioning block is arranged on the base, a vertical positioning groove is arranged on the front and rear side surfaces of the positioning block, a cylinder is arranged on the left and right sides of the positioning block, and the piston rods of the two cylinders are facing opposite directions, the piston rods of the cylinders are connected to the pressure plates, and the cylinders can drive the corresponding pressure plates to flip so as to press the corresponding workpieces in the positioning grooves.

[0005] Preferably, the pressure plate is connected to the base via a pivot to achieve flipping, a strip through hole is provided on the pressure plate, one end of the piston rod of the cylinder is connected to the strip through hole via a threaded piece, and when the piston rod of the cylinder pushes the pressure plate, the threaded piece can move along the strip through hole.

[0006] More preferably, the positioning groove is a V-shaped groove.

[0007] More preferably, a height pad for placing a workpiece is detachably connected to the base on one side of the positioning groove.

[0008] More preferably, a frame is provided at the bottom of the base.

[0009] Compared with the prior art, the present invention can clamp two plunger workpieces at the same time, significantly improving the processing efficiency. Compared with the traditional device that can only process one workpiece at a time, the production capacity is doubled. In addition, the entire clamping device is compact in design and easy to operate. The piston rod of the cylinder is directly connected to the pressure plate, so that the pressure plate can be easily flipped to clamp or release the workpiece, simplifying the operation process of clamping and removing the plunger, reducing the complexity of the operation, and thus improving the processing efficiency.

[0012] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0013] It should be noted in advance that, in the present invention, unless otherwise clearly specified and limited, the terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, in the present invention, unless otherwise clearly specified and limited, the first feature "on" or "under" the second feature may include the first and second features being in direct contact, and may also include the first and second features not being in direct contact but being in contact through another feature between them.

[0014] like Figures 1 to 3 As shown, a clamping device for plunger milling flange surface includes a base 1, a positioning block 2 is arranged on the base 1, a vertical positioning groove 3 is respectively arranged on the front and rear sides of the positioning block 2, a cylinder 4 is respectively arranged on the left and right sides of the positioning block 2, and the piston rods of the two cylinders 4 are facing oppositely, the piston rods of the cylinders 4 are connected to the pressing plates 5, and the cylinders 4 can drive the corresponding pressing plates 5 to flip so as to press the corresponding workpieces 6 in the positioning grooves 3.

[0015] In the above structure, the pressing plate 5 is connected to the base 1 through a pivot 7 to achieve flipping. Through the design of the pivot 7, the pressing plate 5 can flexibly flip around the base 1, which not only simplifies the process of pressing and releasing the workpiece 6, but also improves the operational flexibility and response speed of the device. In addition, the pivot connection method makes the pressing plate 5 more stable during the flipping process, reducing the offset or damage caused by uneven pressure or improper operation. A strip through hole 8 is provided on the pressing plate 5, and one end of the piston rod of the cylinder 4 is connected to the strip through hole 8 through a threaded member. When the piston rod of the cylinder 4 pushes the pressing plate 5, the threaded member can move along the strip through hole 8. This design allows the piston rod of the cylinder 4 to perform precise linear movement when pushing the pressing plate 5, and the movement of the threaded member along the strip through hole 8 provides a simple and effective transmission mechanism, which ensures that the pressing plate 5 can press the workpiece 6 evenly and stably.

[0016] The positioning groove 3 in this embodiment is a V-shaped groove. The design of the V-shaped groove provides a self-positioning mechanism, so that the workpiece 6 can be automatically aligned and fixed in the correct position. This design not only simplifies the clamping process of the workpiece, but also improves the accuracy and repeatability of positioning, thereby ensuring the processing accuracy during the milling process.

[0017] In addition, a height pad 9 for placing the workpiece 6 is detachably connected to the base 1 on one side of the positioning groove 3. The detachable design of the height pad 9 enables the base 1 to be quickly adjusted to accommodate workpieces 6 of different heights, which greatly improves the flexibility and versatility of the device. By simply replacing or adjusting the height pad 9, the operator can easily handle workpieces of different sizes without complicated adjustments or reconfigurations, thereby improving production efficiency.

[0018] In addition, a frame 10 is provided at the bottom of the base 1. The provision of the frame 10 provides a solid support structure for the entire pressing device, ensuring stability and durability under high pressure and repeated use conditions. The design of the frame 10 also helps to disperse pressure, reduce direct impact on the base 1, extend the service life of the device, and improve the safety of operation.

[0019] Before the processing of the clamping device for the plunger milling flange surface provided in the above embodiment, a height pad 9 of appropriate thickness is selected according to the height of the plunger workpiece 6 to be processed to ensure that the workpiece can be correctly placed in the V-groove. Then the height pad 9 is installed on one side of the positioning groove 3 of the base 1. At the beginning of the clamping work, the plunger workpiece 6 to be processed is placed in the V-groove of the positioning block 2. Due to the design of the V-groove, the workpiece 6 will be automatically aligned and fixed in the correct position. Then the cylinder 4 is started. Since the piston rod of the cylinder 4 is connected to the pressing plate 5, as the piston rod moves, the pressing plate 5 can be quickly pushed to flip around the pivot 7, thereby clamping the workpiece 6 to ensure that the workpiece remains stable during the milling process. After the plunger workpiece 6 is clamped, the milling equipment is started to mill the flange surface of the workpiece. Since the workpiece has been stably clamped, the accuracy and quality of the processing process can be guaranteed. In addition, since two workpieces 6 are clamped on the front and back sides of the positioning block 2 at the same time, the flange surfaces at the top of the two workpieces 6 can be milled at one time, greatly improving the processing efficiency. After the milling process is completed, the action of the cylinder 4 is stopped by the control unit, and the piston rod will move in the reverse direction, causing the pressure plate 5 to flip back to the initial position and release the plunger workpiece 6.

[0020] The present invention is a high-efficiency clamping device for plunger milling flange surface. The principle is to realize rapid positioning of a workpiece 6 by setting a vertical V-shaped groove on a positioning block 2 on a base 1, and to drive the respective pressing plates 5 to flip to realize uniform clamping by using reverse cylinders 4 arranged on both sides, and to improve the stability and smoothness of the flipping of the pressing plates 5 by connecting a pivot 7 and a threaded part, thereby improving processing efficiency and accuracy, ensuring the simplicity of operation, the compactness of the structure, and the stability and safety of the processing process.

[0021] In order to make it easier for ordinary technicians in the field to understand the improvements of the present invention over the prior art, some drawings and descriptions of the present invention have been simplified, and the above-mentioned embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
