DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] The existing oil cylinder includes an irregular cylinder body 4, which includes a main body 41 and a convex portion 42 protruding from the main body 41. When the inner hole of the irregular cylinder body 4 is processed, it is impossible to clamp and position it with a three-jaw clamp on a traditional lathe. If a four-jaw clamp capable of fixing the irregular cylinder body is not purchased, it is difficult to fix the oil cylinder. Purchasing a four-jaw clamp increases the processing cost.

[0028] In order to solve the above technical problems, this embodiment provides a cylinder positioning jacket structure, please refer to Figures 1 to 4 As shown, Figure 1 This is a top view of the oil cylinder positioning jacket structure in the embodiment. Figure 2 This is the front view of the oil cylinder positioning jacket structure in the embodiment. Figure 3 This is a three-dimensional diagram of the irregular cylinder body positioned in the jacket in the embodiment. Figure 4 1 is a top view of the jacket in the embodiment.

[0029] The present embodiment provides a cylinder positioning jacket structure, which includes: a jacket 1 , a locking member 2 and a positioning block 3 .

[0030] A positioning hole 10 is provided in the middle of the jacket 1, which is used to place the irregular cylinder body 4, and includes a main hole 101 adapted to the shape of the main body 41, and a side hole 102 adapted to the shape of the protrusion 42; the locking piece 2 is used to fix the irregular cylinder body 4 on the jacket 1; there are three positioning blocks 3, which are respectively fixed on the jaws of the lathe three-jaw clamp 5, and are used to clamp and fix the jacket 1 between the positioning blocks 3.

[0031] The design of the oil cylinder positioning jacket structure of the above technical solution takes into account the characteristics of the irregular cylinder body 4 of the oil cylinder. First, through the positioning hole 10 in the middle of the jacket 1, especially the main hole 101 adapted to the shape of the main body 41 and the side hole 102 adapted to the shape of the convex portion 42, the irregular cylinder body 4 is accurately positioned, ensuring that the oil cylinder maintains a stable positioning during the processing or assembly process, and improving the accuracy and efficiency of the operation; secondly, the use of the locking member 2 enables the irregular cylinder body 4 to be firmly fixed on the jacket 1, and the structure and size of the locking member 2 can be adjusted according to actual needs to ensure sufficient fixing force to prevent the oil cylinder from moving or loosening during the processing or operation, thereby ensuring the stability and safety of the operation; in addition, through the design of the positioning block 3, the jacket 1 can be firmly clamped and fixed between the jaws of the lathe three-jaw clamp 5 to form the effect of a rotating body, ensuring the coaxiality of the irregular cylinder body, not only improving the stability of the jacket 1, but also enabling the entire positioning jacket structure to be effectively coordinated with processing equipment such as a lathe, thereby improving the accuracy and efficiency of processing inner holes and sealing grooves.

[0032] When the oil cylinder positioning jacket structure of the above technical solution is working, the irregular cylinder body 4 of the oil cylinder is placed in the positioning hole 10 of the jacket 1, and the main body 41 is positioned through the main hole 101, and the convex part 42 is positioned through the side hole 102. Then, the irregular cylinder body 4 and the jacket 1 are relatively fixed by the locking member 2, and the jacket 1 is then placed between the positioning blocks 3. Finally, the three-jaw clamp 5 of the lathe is tightened and drives the positioning blocks 3 to fix the jacket 1 between the positioning blocks 3, so that the irregular cylinder body 4 is fixed on the three-jaw clamp 5. It can be seen that the oil cylinder positioning jacket structure of the above technical solution is fixed in sequence by the irregular cylinder body 4, the jacket 1, the positioning block 3 and the three-jaw clamp 5, so that the irregular cylinder body 4 is fixed on the basis of the three-jaw clamp 5 of the traditional lathe, without the need for a four-jaw clamp, and has the advantage of reducing processing costs.

[0033] For example, see Figure 1 As shown, the jacket 1 is cylindrical, that is, the outer contour of the jacket 1 is cylindrical, and an arc surface 30 is provided on the inner side of the positioning block 3. The arc surface 30 is used to fit with the cylindrical surface of the jacket 1. Such a setting can ensure that the jacket 1 and the positioning block 3 fit closely, reduce friction and vibration during clamping, and improve the stability and accuracy of clamping.

[0034] For example, see Figure 3 and Figure 4 As shown, mutually perpendicular bevels 103 and chamfered edges 104 connected between the bevels 103 are provided on the inner side of the main hole 101. Such a setting can accurately locate the contour and chamfer of the cylinder body 41, further improving the accuracy and stability of positioning, that is, the setting of the bevels 103 and the chamfered edges 104 can match the shape characteristics of the irregular cylinder body 4, ensuring the stable placement of the cylinder body in the jacket 1.

[0035] For example, see Figure 1 and Figure 4 As shown, there are two side holes 102, which are symmetrically arranged with the main hole 101 as the center. Such an arrangement can balance the clamping force and ensure the stability of the cylinder boss 42 during processing or assembly. The symmetrically arranged side holes 102 can also reduce stress concentration during clamping and improve the uniformity and reliability of clamping.

[0036] For example, see Figure 1 As shown, the main hole 101 is used to position the cylinder tube 43 of the oil cylinder, and the side hole 102 is used to position the support plate 44 of the oil cylinder, which can achieve accurate positioning of different parts of the oil cylinder and improve the accuracy and reliability of the overall assembly of the oil cylinder.

[0037] In one embodiment of the above-mentioned locking member 2 fixing the irregular cylinder 4 on the jacket 1, see Figure 1 and Figure 2 As shown, the locking member 2 is a locking bolt, and the jacket 1 is provided with a threaded hole 11 connected to the positioning hole 10 and the outside. The locking bolt passes through the threaded hole 11 and presses against the irregular cylinder body 4 in the positioning hole 10. The locking bolt makes the locking operation easier and more efficient, and can provide sufficient locking force to ensure the stability of the cylinder during processing or assembly to prevent it from moving or loosening.

[0038] The number of exemplary locking bolts is 3, which respectively tighten the irregular cylinder body 4 from different directions.

[0039] For example, see Figure 4 As shown, the jacket 1 is a symmetrical structure, and the positioning holes 10 are symmetrically arranged with respect to the symmetry center of the jacket 1. This can not only reduce deformation or damage caused by uneven force, but also simplify the manufacturing and assembly process and improve production efficiency.

[0040] Exemplarily, the positioning block 3 is fixed to the lathe three-jaw fixture 5 by welding.

[0041] For example, see Figure 2 As shown, the lathe three-jaw clamp 5 has its palm facing upward, and the bottom of the jacket 1 is positioned by the clamping jaws of the three-jaw clamp 5 .

[0042] Exemplarily, the jacket 1 is made of stainless steel.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
