The various embodiments of this utility model are described in detail below with reference to the accompanying drawings. Example 1

[0015] Please see Figures 1 to 6 The present invention preferably provides the following technical solution: a drilling fixture for a hydraulic cylinder end cover flange, comprising: a frame; a first assembly plate 113 and a second assembly plate 114 respectively mounted on the upper and lower parts of the frame; a drilling head mechanism and a protective cover mechanism respectively disposed on the first assembly plate 113 and the second assembly plate 114, wherein the drilling head mechanism includes a slide rail 118 fixed to the middle of the first assembly plate 113, and a sliding sleeve 119 rotatably mounted inside the slide rail 118; and a first meshing transmission assembly mounted on the slide rail 118 and used for the rotation of the sliding sleeve 119; a mounting plate 120 is also provided at the bottom of the sliding sleeve 119, and the mounting plate 120 is connected to a rotating shaft. The machine includes a ring-shaped mounting sleeve 122, on which a drill bit body 131 is detachably mounted. A second meshing transmission assembly is provided between several mounting sleeves 122. When the first meshing transmission assembly is running, several drill bit bodies 131 switch drilling positions. When the second meshing transmission assembly is running, several drill bit bodies 131 rotate synchronously to achieve multi-hole operation. The machine also includes a transmission rod provided between the first assembly plate 113 and the second assembly plate 114 for longitudinal sliding of the first assembly plate 113 and the second assembly plate 114 on the frame to realize the lifting operation of the drill head mechanism and the protective cover mechanism.

[0016] like Figure 1 , 3 As shown in Figure 4, a drilling head mechanism and a protective cover mechanism are respectively mounted on the first assembly plate 113 and the second assembly plate 114 on the upper and lower parts of the frame. The sliding sleeve 119 where the drilling head mechanism is located is slidably mounted on the slide rail 118. The slide rail 118 is fixed in the middle of the first assembly plate 113. At the same time, the side wall of the sliding sleeve 119 is provided with a first meshing transmission component to drive its rotation. The bottom of the sliding sleeve 119 is provided with a mounting plate 120. The mounting plate 120 is also provided with a mounting sleeve 122 in a ring through a rotating shaft 121. Each mounting sleeve 122 is detachably mounted with a drill bit body 131. A second meshing transmission component for its rotation is provided between several mounting sleeves 122. The above structures successfully solve the pain points of low efficiency, difficulty in ensuring accuracy, poor safety and insufficient flexibility in traditional processing methods. The specific beneficial effects are as follows; First, regarding the design of multiple drill bit bodies 131 rotating as a whole and drilling holes by individual rotation, this design, on the one hand, drives the sliding sleeve 119 to rotate through the first meshing transmission component, which can drive the entire mounting plate 120 and its multiple mounting sleeves 122 and drill bit bodies 131 to rotate as a whole, realizing the rapid switching of different specifications of drill bit bodies 131 or drill bit bodies 131 of the same specification to change the hole position; on the other hand, through the second meshing transmission component, multiple drill bit bodies 131 can rotate synchronously, realizing the simultaneous processing of multiple holes on the flange end cover at one time, which is several times more efficient than drilling holes one by one on a traditional single-axis drilling machine. Secondly, it effectively ensures processing accuracy and consistency. Since all drill bit bodies 131 are assembled on a common mounting plate 120 via rotating shaft 121 and are precisely and synchronously driven by the second meshing transmission assembly, it ensures that the center distance and relative position between multiple drill bit bodies 131 have extremely high consistency, avoiding the cumulative error caused by drilling in stages. At the same time, the rotational cooperation of slide rail 118 and slide sleeve 119, as well as the first and second meshing transmission assemblies, are used for driving, resulting in smooth transmission and no backlash. This makes the switching and positioning of the drill bit station accurate and reliable, ensuring the hole position accuracy of each workpiece during mass production. In addition, the meshing method has stable power transmission, large torque, and long service life. Third, the detachable design of the drill bit body 131 makes it very convenient to replace and maintain the drill bit body 131. At the same time, the mounting plate 120 in this application is preferably detachable. Therefore, by replacing the mounting plate 120 of different specifications, this tooling can adapt to hydraulic cylinder end cover flanges with different hole diameters and different hole spacing requirements, and has strong versatility. 1. The first assembly plate 113 and the second assembly plate 114 on the frame are connected by a transmission rod and can be flexibly raised and lowered. This design controls the longitudinal sliding of the first and second assembly plates 114 through the transmission rod, which can flexibly adjust the drilling depth to adapt to different thicknesses and enhance the applicability of the tooling. Fifth, it significantly enhances operational safety and environmental friendliness. During drilling operations, the protective cover mechanism can adaptively lower and cover the processing area of ​​the flange. This design can effectively prevent iron filings from flying, protect the safety of operators, and improve the working environment. At the same time, the entire processing process, including the lifting and lowering of the drill bit body 131, the switching of work positions, and synchronous drilling, can be achieved through the drive transmission rod and the first and second meshing transmission components, reducing the chance of operators directly contacting dangerous areas and lowering the risk of work-related injuries.

[0017] Furthermore, the first meshing transmission assembly includes an extension plate 125 fixed to one side of the slide rail 118, with a first motor 1251 disposed at the bottom of the extension plate 125; and a drive gear 126 fixed to the output end of the first motor 1251; and also includes an outer toothed ring 124 fixed to the outer periphery of the slide sleeve 119 and meshing with the drive gear 126.

[0018] like Figure 1 , 2 As shown in Figures 3, 5, and 6, the external gear ring 124 is fixed to the sliding sleeve 119, and the drive gear 126 meshing with the external gear ring 124 is fixed to the output end of the first motor 1251. The first motor 1251 is then mounted on the slide rail 118 via the extension plate 125, as detailed below. Figure 6 As shown, when the first motor 1251 is running, the sliding sleeve 119 can rotate inside the slide rail 118, thereby realizing the synchronous rotation of the mounting plate 120 at the bottom of the sliding sleeve 119 and the several mounting sleeves 122 mounted on the mounting plate 120.

[0019] Furthermore, the second meshing transmission assembly includes a transmission gear 123 fixed on each mounting sleeve 122; a through slot opened in the middle of the first mounting plate 113, the through slot housing a second motor connected to the sliding sleeve 119; and a vertical shaft extending longitudinally through the sliding sleeve 119 and the middle of the mounting plate 120, wherein one end of the vertical shaft is fixed upward to the output end of the second motor, and the other end extends downward toward the mounting plate 120 and is fixed with a central gear 127, and the central gear 127 is built into the middle of a plurality of transmission gears 123 and meshes with the plurality of transmission gears 123.

[0020] like Figure 3 As shown, the second motor 128 passes through the through slot and is connected to the sliding sleeve 119. The vertical shaft fixed at its output end passes downward through the sliding sleeve 119 and the mounting plate 120 and is fixed with a central gear 127. The central gear 127 meshes with the transmission gear 123 fixed on its outer peripheral mounting sleeve 122. Therefore, when the sliding sleeve 119 rotates, the second motor 128 rotates synchronously with the sliding sleeve 119. When the second motor 128 runs alone, the central gear 127 can drive several mounting sleeves 122 to rotate synchronously. Example 2

[0021] In another embodiment of this utility model, the protective cover mechanism includes a through hole 133 annularly formed in the middle of the second assembly plate 114, wherein a plurality of through holes 133 are correspondingly arranged with a plurality of drill bit bodies 131; and a cover body 132, which is disposed on the outer periphery of the through holes 133 and fixed to the bottom of the second assembly plate 114; further, the frame includes a base plate 111 and a plurality of columns 112 fixed on the base plate 111, wherein the first assembly plate 113 and the second assembly plate 114 are slidably mounted on the upper and lower parts of the plurality of columns 112; further, the transmission rod includes a component disposed on the first assembly plate 113, The telescopic linkage assemblies on both sides of the second assembly plate 114 include a telescopic rod 116 and a telescopic sleeve 115 fixed to opposite sides of the first assembly plate 113 and the second assembly plate 114, wherein the bottom end of the telescopic rod 116 extends into the interior of the telescopic sleeve 115; a spring 117 is provided on the outer wall of the telescopic rod 116 between the telescopic sleeve 115 and the first assembly plate 113; and an assembly block 129 is provided on the top of a plurality of columns 112; and a plurality of cylinders 130 are also provided on the bottom of the assembly block 129, and the output ends of the plurality of cylinders 130 extend downward and are connected to the upper surface of the first assembly plate 113.

[0022] like Figure 1 , 3 As shown in Figure 4, since the first assembly plate 113 and the second assembly plate 114 are sleeved on several columns 112 and connected by telescopic rods 116, telescopic sleeves 115 and springs 117, when the cylinder 130 pushes the first assembly plate 113 down, the second assembly plate 114 moves down synchronously with the first assembly plate 113 under the action of the spring 117 until the cover 132 covers the flange and abuts against the bottom plate 111. Then, under the further downward pressure of the cylinder 130, several drill bit bodies 131 can penetrate the through hole 133 and extend into the inside of the cover 132 to drill holes in the flange inside the cover 132. Here, the cover 132 can effectively prevent iron filings from flying and improve the safety of operation.

[0023] Furthermore, a limiting seat is provided directly below the base plate 111 aligned with the protective cover mechanism. The limiting seat includes several limiting grooves 134 formed on the surface of the base plate 111, a limiting plate 135 slidably mounted with the several limiting grooves 134, and several insertion holes 136 formed on the upper surface of the limiting plate 135, and insertion posts 137 adapted to be inserted into the insertion holes 136 for limiting the position of the flange.

[0024] like Figure 1As shown, the limiting plate 135 is installed inside the limiting groove 134 opened on the surface of the base plate 111 to realize the adjustment and locking process of the position of the limiting plate 135. The several insertion holes 136 opened on the surface of the limiting plate 135 can cooperate with the insertion post 137 to realize the process of adjusting the position of the inner and outer supports according to the shape of the flange, thereby improving the stability of the flange drilling operation.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "fixation" and other terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.

[0026] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
