Technical Field

[0001] The utility model relates to the technical field of production and processing of hydraulic oil cylinders, in particular to a fixing device for production and processing of hydraulic oil cylinders. Background Art

[0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. The hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. The cylinder barrel is one of the main components of the hydraulic cylinder. It carries the piston and sealing elements inside the hydraulic cylinder. Since the hydraulic cylinder is connected to the outside world through the inner cavity of the cylinder barrel, the inner wall of the cylinder barrel needs to be processed to improve its surface quality and precision.

Therefore, when processing different cylinder barrels, it is necessary to frequently replace the fixing devices, and even some processing requires manual hand-held fixing, which can easily cause processing errors, thereby affecting the processing accuracy and processing quality. In order to solve the shortcomings of the prior art, we propose a fixing device for the production and processing of hydraulic cylinders. Utility Model Content

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Embodiment 1, as Figure 1-4As shown, a fixing device for the production and processing of hydraulic cylinders is used to clamp and fix the cylinder assembly during the production process of the cylinder body of the hydraulic cylinder. The first clamp 11 and the second clamp 12 can clamp the tubular hydraulic cylinder body with the fixing groove 17 on the inner side. The clamp uses a sliding structure to adjust the distance for cylinder assemblies of different models, thereby changing the clamping distance and accuracy. The staff can drive the rotating shaft 9 to rotate the threaded driving rod 8 connected to the end by turning the hand wheel 10, so that the threaded driving rod 9 drives the connecting rod 7 to rotate, and then the connecting rod The sliding distance adjusting block 3 installed on the outer surface can slide horizontally along the mounting card plate 4. The sliding distance adjusting block 3 is clamped into the upper end of the mounting card plate 4 through the sliding seat 18 at the bottom, so that the horizontal movement direction of the sliding distance adjusting block 3 is stable. The No. 1 clamp 11 and the No. 2 clamp 12 are respectively installed on the upper ends of the two groups of sliding distance adjusting blocks 3. When the sliding distance adjusting block 3 slides and moves, the device plays the function of adjusting the relative position between the two groups of clamps to clamp the cylinder bodies of different models and sizes. At the same time, the limit blocks 2 at both ends of the processing base 1 play the role of limiting and preventing falling, making the device more practical and safer.

[0023] Embodiment 2, as Figure 1-4 As shown, a fixing device for the production and processing of hydraulic cylinders, when the device is clamped, the cylinder body is fixed by two sets of arc-shaped fixing grooves 17 inside the clamps, and anti-skid gaskets 16 are provided on the inner sides of the two sets of fixing grooves 17. The adjusting bolts 14 and the anti-skid gaskets 16 can be connected by the spacer plates 13 on the outer side of the clamps. The adjusting bolts 14 are rotated, and the telescopic degree of the anti-skid gaskets 16 can be adjusted by the adjusting bolts 14, so that when the clamps are clamping the cylinder body, the anti-skid gaskets 16 can play a role in auxiliary fixation and anti-skid and anti-falling, so that the clamping effect of the device is better.

[0024] How it works

[0025] It should be noted that the utility model is a fixing device for the production and processing of hydraulic cylinders. When in use, the No. 1 clamp 11 and the No. 2 clamp 12 can clamp the tubular hydraulic cylinder body with the fixing groove 17 on the inner side. The clamp utilizes a sliding structure to adjust the distance of cylinder body components of different models, thereby changing the clamping distance and accuracy. The staff can drive the rotating shaft 9 to rotate the threaded drive rod 8 connected at the end by turning the hand wheel 10, so that the threaded drive rod 9 drives the connecting rod 7 to rotate, and then the sliding distance adjusting block 3 installed on the outer surface of the connecting rod can slide horizontally along the mounting card plate 4. The sliding distance adjusting block 3 is clamped into the upper end of the mounting card plate 4 through the sliding seat 18 at the bottom, so that the horizontal movement direction of the sliding distance adjusting block 3 is stable. The clamps 12 are respectively installed on the upper ends of the two groups of sliding distance adjusting blocks 3. When the sliding distance adjusting blocks 3 are slidably displaced, the device adjusts the relative position between the two groups of clamps to clamp the cylinder bodies of oil cylinders of different models and sizes. At the same time, the limit blocks 2 at both ends of the processing base 1 play a role in limiting and preventing falling. When the device is clamping, the cylinder body is fixed by the arc-shaped fixing grooves 17 inside the two groups of clamps. Anti-slip pads 16 are provided on the inner sides of the two groups of fixing grooves 17. The adjusting bolts 14 and the anti-slip pads 16 can be connected by the spacer plate 13 on the outside of the clamp. By rotating the adjusting bolts 14, the telescopic degree of the anti-slip pads 16 can be adjusted by using the adjusting bolts 14, so that when the clamp is clamping the cylinder body, the anti-slip pads 16 can play a role in auxiliary fixation and anti-slip and anti-falling.
