Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder manufacturing technology, specifically a pressure cap positioning and opening device for hydraulic cylinder manufacturing. Background Technology

[0002] After the hydraulic cylinder cap is manufactured, a hole needs to be drilled in its center. Each time a hole is drilled, the worker must mark the center point on the cap before drilling. This marking process is prone to errors, resulting in defective products, wasting time and effort, and affecting the drilling progress. To address this, utility model patent application number 202121824900X discloses a cap positioning and drilling device for hydraulic cylinder production. This device uses a limiting mechanism to restrict the position of the hydraulic cylinder cap, ensuring it remains in the center of the drill bit. This saves workers time on marking. A displacement mechanism controls the drill bit to move downwards at a uniform speed, preventing excessively fast downward movement that could cause cracks at the opening position of the hydraulic cylinder cap. This facilitates operation and improves work efficiency.

[0003] However, in practical applications, the device requires manual operation to rotate the gear ring to clamp the cap, but it is difficult to effectively fix the cap. The vibration generated during drilling can easily cause the clamp to loosen, which in turn causes the drilling to deviate and affects the drilling accuracy, so it needs to be improved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a pressure cap positioning and opening device for hydraulic cylinder production.

[0005] To solve the above problems, the technical solution of this utility model is: a pressure cap positioning and opening device for hydraulic cylinder production, including a base, a fixing frame fixedly connected to the rear end of the base, and a drilling mechanism installed inside the fixing frame;

[0006] The base is supported by a support column. The support has a mounting groove on its top and a positioning seat inside the mounting groove. The positioning seat has a through hole in the middle and a limiting ring that matches the pressure cover is fixed to its top. Positioning frames are installed on both sides of the through groove on the top of the support. An electric push rod is installed inside the positioning frame. A Y-shaped pressure strip is installed at the output end of the electric push rod. A pressure block is fixed to the bottom of the pressure strip.

[0007] Furthermore, the drilling mechanism includes an electric actuator 2, the output end of which is equipped with an equipment box, a motor is installed inside the equipment box, and the output shaft of the motor is connected to a drill bit via a coupling.

[0008] Furthermore, the top of the fixed frame is symmetrically fixed with limiting cylinders on both sides of the electric push rod, and the equipment box is fixed with limiting plates inserted inside the limiting cylinders on both sides.

[0009] Furthermore, the mounting groove has a through groove in the middle, and the positioning seat is installed on the support seat by bolts.

[0010] Furthermore, a rectangular annular groove is formed on the top surface of the support base between the through hole and the limiting ring. An annular plate is provided in the groove, and multiple vertical rods passing through the support base are fixed to the bottom of the annular plate. A horizontal plate is fixed to the bottom of the vertical rods.

[0011] Furthermore, an electric actuator three is installed on the top of the base below the horizontal plate, and a push plate is installed at the output end of the electric actuator three.

[0012] The advantages of this utility model compared with the existing technology are as follows: This utility model can limit the position of the pressure cap by cooperating with the positioning seat and the limiting ring. When the electric push rod extends, it causes the pressure strip to move downward to press and fix the two sides of the pressure cap, thereby improving the stability of the pressure cap during drilling and improving the hole opening quality.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 4 As shown, a pressure cap positioning and hole-opening device for hydraulic cylinder production includes a base 1. A fixing frame 2 is fixedly connected to the rear end of the base 1. A drilling mechanism is installed inside the fixing frame 2. The drilling mechanism includes an electric actuator 11. An equipment box 12 is installed at the output end of the electric actuator 11. A motor is installed inside the equipment box 12. The output shaft of the motor is connected to a drill bit 13 through a coupling. Limiting cylinders 14 are symmetrically fixed to the top of the fixing frame 2 on both sides of the electric actuator 11. Limiting plates 15 inserted inside the limiting cylinders 14 are fixed to both sides of the equipment box 12.

[0020] The motor is located inside the equipment box 12 and is not shown in the figure. The motor drives the drill bit 13 to rotate, and the drill bit 13 can be moved up and down by the extension and retraction of the electric push rod 11 to complete the drilling.

[0021] The base 1 is supported by a support column 3. The support 4 has an installation groove on its top. A positioning seat 5 is installed inside the installation groove. The installation groove has a through groove in the middle. The positioning seat 5 is installed on the support 4 by bolts. The positioning seat 5 has a through hole in the middle. A limiting ring 6 that matches the pressure cover is fixed to the top. Positioning frames 7 are installed on both sides of the through groove on the top of the support 4. An electric push rod 8 is installed inside the positioning frame 7. A Y-shaped pressure strip 9 is installed at the output end of the electric push rod 8. A pressure block 10 is fixed to the bottom of the pressure strip 9.

[0022] The pressure cap to be drilled is placed inside the limiting ring 6. The extension and retraction of the electric actuator 8 causes the pressure strip 9 to move up and down. The pressure strip 9, in conjunction with the pressure block 10, can clamp and fix both sides of the pressure cap. When drilling holes in different models of pressure caps, it is only necessary to replace the positioning seat with a different limiting ring 6.

[0023] The top surface of the support base 4 has a rectangular annular groove between the through hole and the limiting ring 6. An annular plate 16 is provided in the groove. Multiple vertical rods 17 passing through the support base 4 are fixed to the bottom of the annular plate 16. A horizontal plate 18 is fixed to the bottom of the vertical rods 17. An electric actuator 19 is installed on the top of the base 1 below the horizontal plate 18. A push plate 20 is installed at the output end of the electric actuator 19.

[0024] After drilling is completed, the electric actuator 18 retracts, and then the electric actuator 319 extends, causing the push plate 20 to lift the annular plate 16 through the horizontal plate 18 and the vertical rod 17. The annular plate 16 lifts the pressure cap, making it easier to remove the pressure cap.

[0025] In practical use, a PLC controller is installed on one side of the front end of the support base 4. The pressure plate to be drilled is placed in the limiting ring 6. The electric push rod 8 extends to cause the pressure bar 9 to move downward to press and fix the two sides of the pressure plate. The electric push rod 11 extends to cause the drill bit 13 to move downward to complete the drilling. After the drilling is completed, the electric push rod 8 retracts to cause the pressure bar 9 to return to its original position. Then the electric push rod 19 extends to cause the annular plate 16 to lift the pressure plate, so that the pressure plate can be easily removed.
