Description

Technical Field

[0001] The utility model relates to the field of printing and dyeing equipment, in particular to a cylinder fixing device. Background Art

[0002] In the industrial printing industry, pneumatic cylinders are a common piece of equipment. They extend and retract to load printed products in batches. Our company currently uses a cylinder that is fixed at one end and extends and retracts at the other to achieve feeding. However, during use, we discovered that the cylinder shaft rotates during operation, causing the wire to back out at the fixed end, which in turn causes the cylinder to shift, affecting its stroke. This also requires frequent machine stops for adjustments, significantly impacting work efficiency.

[0003] To this end, our company proposes a cylinder fixing device. Summary of the Invention

[0004] The purpose of the utility model is to provide a cylinder fixing device, which can prevent the cylinder shaft from rotating during operation and ensure the accurate stroke of the cylinder.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A cylinder fixing device, the cylinder has a cylinder shaft, a square portion is provided at the front end of the cylinder shaft, a threaded hole is provided in the cylinder shaft, a fixing bolt is screwed into the threaded hole, and the fixing bolt is provided on a fixing frame. The cylinder fixing device includes a fixing kit, a first fixing portion matching the outer edge of the square portion and a second fixing portion matching the outer edge of the fixing frame are provided in the fixing kit, a top screw hole is provided on the side wall of the fixing kit, and a top screw for tightening the fixing frame or the square portion is passed through the top screw hole.

[0007] Preferably, the side wall of the fixing frame is provided with an opening for the end of the top screw to pass through.

[0008] Preferably, the length of the second fixing portion is not less than the length of the fixing bolt.

[0009] Preferably, a third fixing portion matching the outer edge of the fixing bolt is further provided between the first fixing portion and the second fixing portion in the fixing kit.

[0010] Preferably, the length of the third fixing portion is smaller than the length of the fixing bolt.

[0011] Preferably, the side wall of the fixing frame is provided with scale lines showing the moving distance of the fixing kit.

[0012] The beneficial effects of the present invention are:

[0013] 1. During use, the guiding of this fixing kit is achieved through the first fixing part, and the axial positioning of the square part of the cylinder is carried out through the second fixing part to prevent it from rotating during use, which may cause the fixing bolt to become loose and affect the stroke accuracy.

[0014] 2. An opening for the setscrew to penetrate is also provided on the side wall of the fixing frame, which can better fix the fixing kit and make the fixing effect better.

[0015] 3. A third fixing part is provided inside the fixing kit, and the axial positioning of the fixing kit can be achieved through the fixing bolt, reducing the processing difficulty of the first fixing part in the fixing kit. Description of the Drawings

Detailed Embodiments

[0025] The present utility model will be further described below with reference to the drawings.

[0026] First Embodiment

[0027] As Figure 1 and 2As shown in the figure, it is a schematic diagram of the installation of a cylinder and the cylinder. The cylinder 1 has a cylinder shaft 11. The front end of the cylinder shaft 11 is provided with a square part 12. A threaded hole 13 is opened in the cylinder shaft 11. A fixing bolt 21 is screwed into the threaded hole 13. The fixing bolt 21 is arranged on the fixing bracket 2.

[0028] As Figure 3 — Figure 5 shown, the cylinder fixing device of this device includes a fixing kit 3. The fixing kit 3 is provided with a first fixing part 31 that matches the outer edge of the square part 12 and a second fixing part 32 that matches the outer edge of the fixing bracket 2. A set screw hole 33 is opened on the side wall of the fixing kit 3. A set screw (not shown in the figure) for tightly pressing the fixing bracket 2 or the square part 12 is inserted into the set screw hole 33. An opening (not shown in the figure) for the end of the set screw to penetrate is provided on the side wall of the fixing bracket 2. The length of the second fixing part 32 is not less than the length of the fixing bolt 21.

[0029] As Figure 6 shown, the first fixing part 31 is clamped outside the square part 12, which can conveniently fix the cylinder 1. Through the setting of the second fixing part 32, a certain guiding function can be achieved. When installing the equipment, the fixing kit 3 can be first sleeved into the right end of the fixing bracket 2, and then moved to the left to an appropriate position. Then, the fixing bolt 21 is screwed into the threaded hole 13 to fix the cylinder shaft 11. After that, the fixing kit 3 is moved to the right until the set screw hole 33 corresponds to the opening on the fixing bracket 2 (at this time, the first fixing part 31 is clamped outside the square part 12), and the set screw is inserted to fix the fixing kit 3, the square part 12 and the cylinder shaft 11, so as to prevent them from rotating during use and causing the fixing bolt 21 to unscrew, affecting the stroke accuracy.

[0030] In order to facilitate the positioning of the fixing kit 3 and facilitate the correspondence between the set screw hole 33 and the opening of the fixing bracket 2, a scale line (not shown in the figure) for displaying the moving distance of the fixing kit 3 is provided on the side wall of the fixing bracket 2.

[0031] Embodiment 2

[0032] In this embodiment, the schematic diagram of the installation of the cylinder and the cylinder is the same as that in Embodiment 1.

[0033] Due to the large outer diameter of the fixing bracket 2, during the processing of the fixing kit 3, it will cause the inner hole of the second fixing part 32 to be difficult to machine. Therefore, in this application, the cooperation between the third fixing part 34 and the fixing bolt 21 is used to guide the fixing kit 3. The third fixing part 34 is located between the first fixing part 31 and the second fixing part 32, and its length is less than the length of the fixing bolt 21, which can realize the left and right movement of the fixing kit 3.

[0034] In some embodiments, the partial fixing kit 3 having the second fixing portion 32 can adopt conventional parts such as steel pipes and sleeves. Its inner diameter does not need to be matched with the outer edge of the fixing frame, and it is only necessary to ensure that its inner diameter is larger than that of the fixing frame 2. Then, it is integrated with the fixing kit 3 provided with the first fixing portion 31 and the third fixing portion 34 (welding or other forms can be used). Finally, a set screw hole 33 (or a smooth hole) is opened on its side wall, and a set screw is inserted to realize the fixation with the fixing frame 2.

[0035] The other structures of this embodiment are the same as those of the first embodiment.

[0036] The above embodiments do not impose any formal restrictions on the shape, material, structure, etc. of the present invention. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention all belong to the protection scope of the technical solution of the present invention.
