Description

Technical Field

[0001] This utility model relates to the field of hydraulic mechanism technology, and in particular to a non-standard auxiliary clamping hydraulic mechanism. Background Technology

[0002] In industrial manufacturing, especially in processes involving assembly, welding, riveting, or workpiece positioning, hydraulic clamping mechanisms are widely used due to their high output and smooth, reliable operation. These mechanisms typically utilize hydraulic cylinders to drive a piston rod in linear motion, which is then converted into clamping force on the workpiece through a specific transmission structure.

[0003] Currently common hydraulic clamping mechanisms, especially auxiliary clamping devices used in non-standard automated equipment or tooling fixtures, typically employ rigid connections. For example, the piston rod acts directly or through a simple connector on the pressure head or block, or the force is amplified via a lever mechanism. However, these traditional structures have some significant drawbacks:

[0004] Many clamping cylinders are quite large, which can cause inconvenience in use, such as interference between the workpiece and the cylinder, interference between the cutting tool and the cylinder, and a series of other problems. Secondly, they have poor rigidity and adaptability. When the pressure head directly contacts the workpiece or the end of the stroke, it is easy to generate rigid impact, which may not only damage the surface of the workpiece, but also cause impact load on the clamping mechanism itself, affecting its service life.

[0005] Therefore, there is an urgent need for a non-standard auxiliary clamping hydraulic mechanism to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a non-standard auxiliary clamping hydraulic mechanism to solve the problems mentioned in the background art, such as the large volume of existing clamping cylinders causing interference between the cylinder volume and the workpiece and the tool position, as well as the rigid impact caused when the pressure head contacts the workpiece.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a non-standard auxiliary clamping hydraulic mechanism, comprising a cylinder body and a sealing plate sealed at the bottom of the cylinder body, a piston rod is disposed inside the cylinder body, a pressure plate is disposed above the cylinder body, a pin is rotatably connected to the top end of the piston rod and one end of the pressure plate, a hinge for supporting the pressure plate is pivotally connected to the outer wall of the pressure plate, a clamping block is detachably disposed at the bottom end of the pressure plate, and a retractable elastic sleeve is provided between the clamping block and the pressure plate.

[0008] Preferably, the hinge includes a connecting plate fixed to the top surface of the cylinder body, a hinge plate fixed to the top surface of the connecting plate, a hinge piece between the pressure plate and the hinge plate, and hinge pins at both ends of the hinge piece, which are hinged to the pressure plate and the hinge plate.

[0009] Preferably, a screw is fixed to the top of the clamping block, and a threaded hole adapted to the screw is opened at the bottom of the pressure plate.

[0010] Preferably, the bottom end of the clamping block is provided with an anti-slip plate.

[0011] Preferably, the top end of the elastic sleeve is detachably connected to the pressure plate, and the bottom end is detachably connected to the clamping block, for providing elastic buffering and stroke compensation functions.

[0012] Preferably, the elastic sleeve includes an outer cylinder and an inner cylinder that is slidably inserted into the outer cylinder. A limiting plate is fixed at the top of the inner cylinder, and a spring abuts against the limiting plate and the inner cavity of the outer cylinder.

[0013] Preferably, the top end of the outer cylinder is fixedly connected to a second screw rod that matches the threaded hole of the pressure plate, and the bottom end of the inner cylinder is provided with a mounting screw hole that matches the first screw rod.

[0014] The technical effects and advantages of this utility model are as follows: This utility model achieves the reciprocating motion of the piston rod inside the cylinder by filling it with oil, thereby realizing the pressing and releasing action of the hydraulic mechanism. Compared with the existing lever mechanism, it can reduce the volume. Secondly, the elastic sleeve can realize the elastic buffer and stroke compensation function between the pressing block and the workpiece, avoiding excessive rigid impact of the pressing block and causing damage to the workpiece.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1-4 The non-standard auxiliary clamping hydraulic mechanism shown includes a cylinder body 1 and a sealing plate 7 sealed at the bottom of the cylinder body 1. A piston rod 2 is arranged inside the cylinder body 1, and a pressure plate 6 is provided above the cylinder body 1. The top end of the piston rod 2 and one end of the pressure plate 6 are rotatably connected to a pin 5. A hinge for supporting the pressure plate 6 is pivotally connected to the outer wall of the pressure plate 6. A clamping block 8 is detachably arranged at the bottom end of the pressure plate 6. A telescopic elastic sleeve 9 is provided between the clamping block 8 and the pressure plate 6.

[0022] In view of the problem that the hydraulic cylinders of existing clamping devices are relatively large, causing interference between the cylinder size and the workpiece and the tool position, as well as rigid impact when the pressure head contacts the workpiece, this utility model proposes a non-standard auxiliary clamping hydraulic mechanism. First, the cylinder body 1 is filled with oil to realize the reciprocating motion of the piston rod 2 inside the cylinder body 1, thereby realizing the clamping and releasing action of the hydraulic mechanism. Compared with the existing lever mechanism, the volume can be reduced. Secondly, the elastic sleeve 9 can realize the elastic buffer and stroke compensation function between the clamping block 8 and the workpiece, avoiding excessive rigid impact of the clamping block 8 and damage to the workpiece.

[0023] In use, the cylinder body 1 is first filled with oil to raise the piston rod 2, which in turn pushes one end of the pressure plate 6 to move upward. Since the pressure plate 6 is pivotally connected to the middle, one end of the pressure plate 6 is pressed down to achieve the fastening effect on the workpiece. Conversely, the hydraulic mechanism is released.

[0024] like Figure 1 As shown, the fixed hinge component includes a connecting plate 3 fixed to the top surface of the cylinder body 1. A hinge plate 31 is fixed to the top surface of the connecting plate 3. A hinge piece 4 is provided between the pressure plate 6 and the hinge plate 31. A hinge pin 41 is provided at both ends of the hinge piece 4. The hinge pins 41 at both ends of the hinge piece 4 are hinged to the pressure plate 6 and the hinge plate 31.

[0025] like Figure 1 and Figure 3 As shown, a screw 82 is fixedly connected to the top of the clamping block 8, and a threaded hole adapted to the screw 82 is opened at the bottom of the pressure plate 6.

[0026] The clamping block 8 is fixed with a screw 82 that matches the threaded hole at the bottom of the pressure plate 6, thereby enabling the quick replacement of the clamping block 8.

[0027] like Figure 3 As shown, the bottom end of the clamping block 8 is provided with an anti-slip plate 81. The anti-slip plate 81 increases the friction between the clamping block 8 and the workpiece when the clamping block 8 comes into contact with the workpiece, making the clamping more secure.

[0028] like Figure 2 and Figure 4 As shown, a retractable elastic sleeve 9 is provided between the clamping block 8 and the pressure plate 6. The top end of the elastic sleeve 9 is detachably connected to the pressure plate 6, and the bottom end is detachably connected to the clamping block 8, which is used to provide elastic buffering and stroke compensation functions.

[0029] like Figure 3 As shown, the elastic sleeve 9 includes an outer cylinder 91 and an inner cylinder 92 that is slidably inserted into the outer cylinder 91. A limiting plate 921 is fixedly provided at the top of the inner cylinder 92, and a spring 93 abuts between the limiting plate 921 and the inner cavity of the outer cylinder 91.

[0030] The inner cylinder 92 is restricted from detaching from the outer cylinder 91 by the limiting plate 921. At the same time, a spring 93 is provided between the limiting plate 921 and the inner cavity of the outer cylinder 91 to increase the stroke compensation function and avoid the clamping block 8 failing to contact the workpiece when facing a small workpiece.

[0031] like Figure 4 As shown, the top of the outer cylinder 91 is fixed with a screw 94 that matches the threaded hole of the pressure plate 6, and the bottom of the inner cylinder 92 is provided with a mounting screw hole 922 that matches the screw 82. The outer cylinder 91 and the pressure plate 6 can be quickly disassembled through the screw 94 at the top of the outer cylinder 91, and the mounting screw hole 922 at the bottom of the inner cylinder 92 can be quickly disassembled and replaced to facilitate maintenance and repair.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
