Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder processing technology, specifically to an automatic positioning and clamping device. Background Technology

[0002] In hydraulic systems, hydraulic cylinders play a crucial role in efficiently converting fluid energy into linear or oscillating mechanical work. Thanks to their inherent structural simplicity, high reliability, and zero backlash, hydraulic cylinders provide smooth and direct reciprocating power, eliminating the need for deceleration, making them an indispensable actuator in many industrial machines. During the machining process of hydraulic cylinders, clamping operations are required for processing.

[0003] Chinese Patent No. CN222472215U discloses an automatic clamping device for hydraulic cylinder processing, including a rotary table. A base is rotatably mounted on the top of the rotary table, and a first motor is fixedly mounted on the side of the rotary table. Two sets of first clamping blocks are movably mounted on the top of the base, and a second clamping block is provided above the two sets of first clamping blocks. The second clamping block is movably mounted on a lifting mechanism. This device, through the design of the first clamping blocks mounted on the top of the base, adapts to cylinders of different specifications by adjusting the distance between the first clamping blocks. The first and second clamping blocks are connected to each other by connecting rods, and the second clamping blocks adjust synchronously. The lifting mechanism drives the second clamping blocks to move closer to the first clamping blocks. The cylinder is clamped and positioned by the cooperation of the first and second clamping blocks, thereby shortening the time spent in the cylinder clamping process and improving production efficiency.

[0004] However, the above technical solution has the following shortcomings: when fixing hydraulic cylinders of different lengths, the device cannot conveniently position the length direction of the cylinder barrel, and can only manually control the position of the cylinder barrel end, which affects the ease of use of the device. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an automatic positioning and clamping device that can quickly position and place hydraulic cylinders of different lengths and sizes, thereby improving the ease of use of the device.

[0012] Preferably, the base is provided with two horizontally movable second clamping blocks.

[0013] Preferably, the rotating machine platform is provided with four mounting blocks having mounting holes.

[0020] Example 1 like Figure 1 - Figure 4 As shown, the present invention proposes an automatic positioning and clamping device, which includes a rotating machine table 1 and a positioning mechanism; a base 2 is provided on the rotating machine table 1, and a first fixed seat 3 and a second fixed seat 4 are provided on the base 2.

[0021] The positioning mechanism includes two guide rods 5 horizontally arranged inside the first fixed seat 3 and the second fixed seat 4 respectively, a slider 6 slidably connected to the guide rods 5, an abutment seat 7 arranged on both sides of the slider 6, an indicator rod 8 arranged on one side of the slider 6, a scale plate 9 arranged on the first fixed seat 3, and a stabilizing component arranged on the other side of the slider 6; the indicator rod 8 points to the scale of the scale plate 9.

[0022] The stabilizing assembly includes a fixing block 18 with three equally spaced threaded holes on the slider 6, three screws 21 threadedly connected to the threaded holes, a pressure plate 19 on the screws 21, and a handle 20 on the pressure plate 19. The second fixing seat 4 has an elongated hole through which the screws 21 pass. A washer 22 is sleeved on the screws 21 and is located between the pressure plate 19 and the second fixing seat 4 and presses against each other.

[0023] In this invention, before clamping and fixing the outer wall of the hydraulic cylinder, the position of the abutment seat 7 is adjusted according to the length of the cylinder in each batch of processing. This ensures that when the cylinder is placed, the processing surface is precisely located at the processing position when the tail end of the cylinder abuts the abutment seat 7. When adjusting the abutment seat 7, simply push and pull the abutment seat 7 to make the slider 6 slide along the guide rod 5, and observe the indicator rod 8 on one side of the slider 6 pointing to the scale on the scale plate 9. When the indicator rod 8 moves to the selected position, stop moving the abutment seat 7, and thread the three screws 21 through the elongated holes on the second fixed seat 4 and screw them into the threaded holes of the fixing block 18 until the pressure plate 19 presses the gasket 22 tightly onto the second fixed seat 4. The fixing block 18 restricts the abutment seat 7, thus facilitating the positioning and placement of hydraulic cylinders of different lengths. The operation is simple and convenient, and it has good practicality.

[0024] Example 2 like Figure 1 and Figure 4 As shown, the automatic positioning and clamping device proposed in this utility model, compared with the first embodiment, further includes a clamping mechanism on the abutment seat 7. The clamping mechanism includes a rotating shaft 10 that is horizontally rotatably disposed inside the abutment seat 7, two symmetrically distributed threaded blocks 13 that are slidably connected inside the abutment seat 7, a first clamping block 14 disposed on the threaded blocks 13, and a transmission component disposed on the abutment seat 7. The rotating shaft 10 has two symmetrically distributed first threaded portions 11 and second threaded portions 12 with opposite thread directions. The threaded blocks 13 on both sides are respectively threadedly connected to the first threaded portions 11 and the second threaded portions 12. The clamping surface of the first clamping block 14 is V-shaped.

[0025] The transmission assembly includes a motor 15 mounted on the abutment seat 7, a first gear 16 drivenly connected to the motor 15, and a second gear 17 coaxially mounted on the rotating shaft 10; the first gear 16 and the second gear 17 are meshed together.

[0026] Two horizontally movable second clamping blocks 23 are provided on the base 2.

[0027] In an optional embodiment, after the cylinder barrel is initially placed by the positioning mechanism, the starter motor 15 drives the first gear 16 to rotate. The first gear 16 and the second gear 17 mesh and drive each other, causing the second gear 17 to drive the rotating shaft 10 to rotate. Then, the first threaded part 11 and the second threaded part 12 on the rotating shaft 10 respectively engage with the threaded blocks 13 on both sides. Then, the threaded blocks 13 drive the first clamping blocks 14 to move closer to each other until the clamping surface of the first clamping blocks 13 clamps the outer wall of the cylinder barrel. The base 2 is provided with a drive structure similar to the clamping mechanism. It also drives the second clamping blocks 23 on both sides to move closer or further away from each other through a bidirectional threaded structure to clamp and fix the side of the cylinder barrel close to the machining surface. It works with the first clamping blocks 14 to clamp and fix the rear end of the cylinder barrel, thereby fully ensuring the stability of the cylinder barrel.

[0028] It should be noted that the positioning mechanism is equipped with a pressure sensor (not shown) to control the clamping force on the cylinder, so as to avoid excessive or insufficient force that could affect the structure and stability of the cylinder.

[0029] Example 3 like Figure 1 As shown, the automatic positioning and clamping device proposed in this utility model, compared with Embodiment 1, further includes four mounting blocks 24 with mounting holes on the rotating machine table 1.

[0030] In an optional embodiment, the mounting block 24 is used to fix the rotary table 1 on the main body of the processing equipment, and the rotary table 1 is provided with a drive device for driving the entire base 2 to rotate. The device adopts the rotary table designed by the utility model with patent publication number CN222472215U, and uses a worm gear transmission method in conjunction with a dial indicator to detect the relative position of the cylinder end face and the processing surface to ensure the processing quality.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
