Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment, and particularly relates to a fixing device for a power cylinder and a connecting beam. Background Art

[0002] In the field of mechanics, hydraulic cylinders and pneumatic cylinders are collectively referred to as power cylinders. The end of the power cylinder piston is provided with an earring, which is connected to a fixed support via bolts. The fixed support is then fixedly connected to the connecting beam, thereby achieving a fixed connection between the power cylinder and the connecting beam. There are various ways to fix the fixed support to the connecting beam, each with its own specific application scenarios and advantages. Common fixing methods include: bolt fixing, welding fixing, bolt and welding fixing, support beam or support rod fixing, and fixing the support to the beam body with stop grooves, locating pins, and bolts.

[0003] Among them, bolt fixing is simple and easy to operate, and is the most commonly used connection method. The fixed support and the connecting beam are connected together by bolts. However, during the operation of the power cylinder, the connection position between the fixed support and the connecting beam is often subjected to force, especially the double-acting power cylinder, which is subjected to forces in two directions at the connection position, causing the screws at the bolts used to fix the fixed support and the connecting beam to be roughened, making the fixation ineffective and causing equipment failure. In addition, the method of bolt plus welding fixation is also a relatively common fixing method. This fixing method may cause the welding parts to open and fall off during the operation of the power cylinder, causing equipment failure. When the fixed position becomes loose and fails, special welding operations are required to reinforce it, which is time-consuming and labor-intensive, affecting the normal production rhythm. Utility Model Content

[0004] The purpose of the utility model is to provide a fixing device for a power cylinder and a connecting beam, which optimizes the connection and fixing structure between the connecting beam and the fixed support to enhance the strength at the fixing position and ensure the safety of equipment operation.

The positioning plates are in an inverted L-shape and protrude from the upper surface of the connecting beam. A slot for accommodating the fixed plate is formed between the plate surface on the positioning plate parallel to the upper surface of the connecting beam and the upper surface of the connecting beam.

[0008] Furthermore, the height of the slot is consistent with the thickness of the fixing plate.

[0009] Furthermore, the distance between the bottoms of the slots of the two positioning plates facing each other is consistent with the width of the fixing plate.

[0010] Furthermore, the connecting fork has a U-shaped groove for accommodating the power cylinder earring, and a fork hole is provided on each side of the U-shaped groove, one fork hole is a smooth hole, and the other fork hole is a threaded hole, and the two fork holes are aligned with the connecting holes on the power cylinder earring inserted into the U-shaped groove, and are fastened together by a first bolt.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention in any way.

[0026] like Figure 1-3 As shown, a fixing device for a power cylinder and a connecting beam is provided. The power cylinder 1 described in this embodiment is a hydraulic cylinder, and the fixing device includes a power cylinder earring 2, a fixing support 3, a first bolt 4, a second bolt 5 and a connecting beam 7.

[0027] The power cylinder earring 2 is arranged at the piston end of the power cylinder 1, has a flat structure, and is provided with a connecting hole.

[0028] The fixing support 3 is T-shaped as a whole, and consists of a connecting fork 301 and a fixing plate 302 that are perpendicular to each other. The connecting fork 301 and the fixing plate 302 can be welded or formed into an integral structure.

[0029] The connecting fork 301 has a U-shaped groove, the width of which is consistent with the thickness of the power cylinder earring 2, so that the power cylinder earring 2 can fit in contact with the inner wall of the U-shaped groove after being inserted into the U-shaped groove. The connecting fork 301 is provided with two coaxial fork holes, one of which is a plain hole and the other is a threaded hole. After the power cylinder earring 2 is installed in the U-shaped groove, the two fork holes and the connecting hole on the power cylinder earring 2 are aligned, so that the first bolt 4 can be passed through the fork hole and the connecting hole to achieve a threaded connection, completing the connection between the power cylinder earring 2 and the fixed support 3. The fixing plate 302 is used to connect to the connecting beam 7. The fixing plate 302 has four through holes that penetrate the surface of the fixing plate 302.

[0030] The upper surface of the connecting beam 7 is provided with bolt holes 8, which are perpendicular to the upper surface of the connecting beam 7, and the bolt holes 8 are distributed in the installation area A for connecting the fixed support 3. Four bolt holes 8 are provided in the installation area A, and the four bolt holes 8 can be aligned one-to-one with the four through holes on the fixing plate 302 to install the second bolts 5, and the second bolts 5 are threadedly connected to the corresponding bolt holes 8. A positioning plate 6 for clamping the fixed support 3 is also provided on the outside of each bolt hole 8. The positioning plate 6 protrudes from the upper surface of the connecting beam 7. The positioning plate 6 is in an inverted L-shape, so that a slot is formed between the positioning plate 6 and the upper surface of the connecting beam 7. The height of the slot is consistent with the thickness of the fixing plate 302 of the fixed support 3, so that after the fixing plate 302 of the fixed support 3 is inserted into the slot, the upper and lower plate surfaces of the fixing plate 302 are respectively in contact with the positioning plate 6 and the connecting beam 7, thereby fixing the fixed support 3 in a direction perpendicular to the upper surface of the connecting beam 7. In this way, the fixed support 3 is reliably connected to the connecting beam 7 through the dual fixation of the second bolt 5 and the positioning plate 6, thereby improving the reliability of the connection between the power cylinder 1 and the connecting beam 7.

[0031] Further, such as Figure 1 As shown, the distance D between the bottoms of the slots of the two positioning plates 6 facing each other is consistent with the width of the fixing plate 302 of the fixing support 3, so that the two sides of the fixing plate 302 can be pressed against the bottoms of the slots of the positioning plates 6, preventing the fixing support 3 from shaking and further ensuring the stability of the connection between the fixing support 3 and the connecting beam 7. At the same time, when the fixing plate 302 slides along the slot, the bottom of the slot provides a guide for the sliding of the fixing plate 302, preventing the fixing plate 302 from tilting and getting stuck.

[0032] When the fixing plate 302 of the fixing support 3 is installed in the slot of the positioning plate 6, the fixing plate 302 slides into the slot from one side until the through hole on the fixing plate 302 is aligned with the bolt hole 8 on the connecting beam 7. Then, the fixing support 3 is fixed with the second bolt 5. At this time, the four positioning plates 6 are respectively clamped at the four corners of the fixing plate 302, limiting the position of the fixing support 3 in a direction perpendicular to the upper surface of the connecting beam 7.

[0033] The connecting beam 7 is a welded assembly formed from multiple metal plates, including two main plates 701 with opposing surfaces and a support plate assembly positioned between the two main plates 701. The support plate assembly comprises a rectangular frame and an installation area reinforcement plate 705. The rectangular frame includes a top support plate 702, a bottom support plate 703, and two end support plates 704. The top and bottom support plates 702, 703 are spaced apart from each other, and the long sides of the top and bottom support plates 702, 703 are welded to the inner side of the main plate 701. The upper surface of the top support plate 702 is flush with the upper surface of the main plate 701. The two end support plates 704 are respectively fixed to the longitudinal ends of the top and bottom support plates 702, 703, thereby forming the rectangular frame. The installation area reinforcement plate 705 is disposed within the rectangular frame and corresponds to the installation area of ​​the connecting beam 7 for connecting to the fixed support 3 to strengthen the strength of the installation area A of the connecting beam 7. Two installation area reinforcement plates 705 with opposite and spaced apart surfaces are provided at positions corresponding to the installation area A in the rectangular frame. The installation area reinforcement plates 705 are parallel to the end support plates 704. The four sides of the installation area reinforcement plates 705 are welded to the top support plate 702, the bottom support plate 703 and the two main boards 701 respectively.

[0034] like Figure 2 As shown, the upper surface of the main board 701 is provided with the bolt holes 8 and the positioning plates 6. At the installation area A of the connecting beam 7, each main board 701 is provided with two bolt holes 8 and two positioning plates 6. The two bolt holes 8 are located between the two positioning plates 6.

[0035] Preferably, the positioning plate 6 and the corresponding main board 701 are an integral structure.

[0036] Furthermore, a baffle is provided in the slot of the two positioning plates 6 on one of the main boards 701, which is used to position the fixing plate 302 of the fixing support 3 installed in the slot. In this way, when the fixing plate 302 is installed in the slot, it slides into the slot from the positioning plate 6 on the other main board 701 until the fixing plate 302 hits the baffle. At this time, the through hole on the fixing plate 302 and the bolt hole 8 on the connecting beam 7 are exactly aligned, which can save the time of adjusting the position of the fixing plate 302 and improve the installation efficiency.

[0037] In this embodiment, two mounting areas A are provided on the connecting beam 7, each of which is connected to two power cylinders 1. In other embodiments, one or more mounting areas A may be provided on the connecting beam 7 according to actual conditions, with each mounting area A being connected to one power cylinder 1.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Those skilled in the art should understand that the specific implementation methods of the present invention can be modified or replaced with equivalents with reference to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the pending claims.
