Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinders, and in particular to a hydraulic cylinder capable of monitoring stroke. Background Technology

[0002] Hydraulic cylinders are the core actuators in hydraulic systems, responsible for converting hydraulic energy into mechanical energy, and are widely used in various types of mechanical equipment.

[0003] When using a hydraulic cylinder, hydraulic oil enters the cylinder body through pipes, driving the piston inside to move. After the hydraulic oil leaves the cylinder, the piston returns to its original position via a spring inside the cylinder. The inability to detect the piston's stroke during movement prevents the determination of the piston's travel distance. This can lead to inaccurate positioning of objects during precision machining, ultimately affecting the performance of the hydraulic cylinder. Utility Model Content

[0004] The technical problem this invention aims to solve is that the stroke cannot be detected when the piston is moving, resulting in an inability to know the piston's movement distance. Consequently, when precision machining certain objects, the object's movement position becomes inaccurate, thus affecting the performance of the hydraulic cylinder.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a hydraulic cylinder with a monitored stroke, including a cylinder body, a piston on one side of the cylinder body, a pipe on one side of the cylinder body, and a monitoring device on one side of the piston. The monitoring device measures the piston stroke through a scale, so that the operator can observe and monitor the piston stroke.

[0006] The effect achieved by the above components is as follows: when using the hydraulic cylinder, the hydraulic oil flows through the cylinder body's pipes to the inside of the cylinder body, thereby driving the piston inside the cylinder body to move. At this time, the monitoring device measures the piston stroke through a scale, allowing the operator to observe and monitor the piston stroke in real time. After the hydraulic oil leaves the cylinder body, the piston is reset by the spring inside the cylinder body.

[0007] Preferably, the monitoring device includes a square tube, a first bolt, and a connecting plate. The square tube is disposed at one end of the piston, and the connecting plate is fixed by the first bolt. A scale is disposed on one side of the connecting plate, and the scale is located on one side of the cylinder body.

[0008] The effect achieved by the above components is as follows: Before the piston moves, the connecting plate is inserted into the square tube fixed to the piston, and then the first bolt is rotated to make the first bolt pass through the square tube and connect with the connecting plate by thread, thus completing the fixation of the position of the connecting plate. Then, the scale fixed on one side of the connecting plate is aligned with the side of the cylinder body. When the piston moves to connect with or in contact with an object, the scale will move with the piston. The operator can then observe the scale in the area where the cylinder body and piston are connected to obtain the piston stroke. Real-time monitoring and viewing of the piston stroke can be achieved. By using the monitoring device, the piston's movement stroke can be measured, allowing the operator to monitor and view the piston stroke in real time. This facilitates the piston inside the cylinder to move the object to the accurate position, thereby improving the performance of the hydraulic cylinder.

[0009] Preferably, a trapezoidal block is provided on the side of the connecting plate away from the scale, and the trapezoidal block reduces the size of one side of the connecting plate.

[0010] The effect achieved by the above components is that by using a trapezoidal block on one side of the connecting plate to reduce the size of one side of the connecting plate, it is easier to insert the square tube into the connecting plate.

[0011] Preferably, a plurality of anti-slip blocks are provided at one end of the first bolt, and the plurality of anti-slip blocks increase the friction at one end of the first bolt.

[0012] The effect achieved by the above-mentioned components is to increase the friction between the first bolt and the operator by fixing several anti-slip blocks to one end of the first bolt, making it easier for the operator to rotate the first bolt.

[0013] Preferably, a rubber sleeve is provided on one side of the connecting plate to cover and protect the corners of the connecting plate.

[0014] The effect achieved by the above components is that the rubber sleeve fixed to the connecting plate allows the operator to better grip the connecting plate for movement, and avoids damage to the operator from the edges and corners of the connecting plate.

[0015] Preferably, the limiting device includes a first limiting block, a slide rail, a sliding block, a second limiting block, and a second bolt. The first limiting block is disposed on the side of the cylinder body close to the scale. The slide rail is located on the side of the first limiting block. The sliding block moves inside the slide rail and drives the second limiting block to the upper end of the scale. The second bolt rotates inside the sliding block and fixes the positions of the sliding block and the second limiting block.

[0016] The effect achieved by the above components is as follows: the first limiting block fixed on the cylinder body limits the scale on both sides of the cylinder body. The sliding block inside the slide rail fixed on one side of the first limiting block moves, causing the sliding block to slide inside the slide rail and drive the second limiting block fixed on one side of the sliding block to the upper end of the scale. Then, the second bolt is rotated, causing the second bolt to rotate inside the sliding block and abut against the slide rail at one end, thus fixing the position of the sliding block and the second limiting block. The second limiting block then limits the upper end of the scale, making the scale movement more stable and allowing the operator to use the scale better. By using the limiting device, the movement trajectory of the scale can be restricted, making the scale move more stably, thereby improving the effectiveness of the monitoring device.

[0017] Preferably, a rubber pad is provided on the side of the slide rail near the second bolt, and the rubber pad increases the friction between the slide rail and the second bolt.

[0018] The effect achieved by the above components is to increase the friction between the second bolt and the slide rail by fixing the rubber pad on one side of the slide rail, so that the second bolt can better abut and fix with the slide rail.

[0019] Preferably, a reinforcing plate is provided inside the slide rail, and the reinforcing plate penetrates the sliding block.

[0020] The effect achieved by the above components is to improve the connection strength between the sliding block and the slide rail by fixing the reinforcing plate inside the slide rail and slidingly connecting it with the sliding block, thereby preventing the slide rail and the sliding block from separating.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] By using a monitoring device, the stroke of the piston can be measured, allowing operators to monitor the piston stroke in real time. This facilitates the piston inside the cylinder in moving the object to the accurate position, thereby improving the performance of the hydraulic cylinder.

[0023] By using a limit device, the movement trajectory of the ruler can be restricted, making the ruler move more stably and thus improving the effectiveness of the monitoring device. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0032] Figures 1 to 4 The hydraulic cylinder shown includes a cylinder body 1, a piston 2 on one side of the cylinder body 1, a pipe 3 on one side of the cylinder body 1, and a monitoring device 4 on one side of the piston 2. The monitoring device 4 measures the stroke of the piston 2 using a scale 44, allowing the operator to observe and monitor the stroke of the piston 2. When the hydraulic cylinder is in use, hydraulic oil flows through the pipe 3 into the cylinder body 1, driving the piston 2 inside the cylinder body 1 to move. At this time, the monitoring device 4 measures the stroke of the piston 2 using the scale 44, allowing the operator to observe and monitor the stroke of the piston 2 in real time. After the hydraulic oil leaves the cylinder body 1, the piston 2 is reset by a spring inside the cylinder body 1.

[0033] Figures 1 to 4The monitoring device 4 shown includes a square tube 41, a first bolt 42 and a connecting plate 43. The square tube 41 is located at one end of the piston 2. The square tube 41 is fixed to the connecting plate 43 by means of the first bolt 42. A scale 44 is provided on one side of the connecting plate 43. The scale 44 is located on one side of the cylinder body 1. Before piston 2 moves, connecting plate 43 is inserted into square tube 41 fixed to piston 2. Then, the first bolt 42 is rotated so that it passes through square tube 41 and is threaded to connecting plate 43, thus fixing the position of connecting plate 43. Then, the scale 44 fixed on one side of connecting plate 43 is aligned with one side of cylinder body 1. When piston 2 moves in contact with or connects to an object, scale 44 will move with piston 2. The operator observes the scale 44 at the connection point between cylinder body 1 and piston 2 to obtain the stroke of piston 2. Real-time monitoring of piston 2 stroke is then achieved. By using monitoring device 4, the stroke of piston 2 can be measured, allowing the operator to monitor piston 2 stroke in real time. This facilitates piston 2 inside cylinder body 1 moving the object to the accurate position, thereby improving the performance of the hydraulic cylinder.

[0034] Figures 1 to 4 A trapezoidal block 45 is provided on the side of the connecting plate 43 away from the scale 44, reducing the size of one side of the connecting plate 43. By reducing the size of one side of the connecting plate 43 with the trapezoidal block 45, the connecting plate 43 can be more easily inserted into the square tube 41. Several anti-slip blocks 46 are provided at one end of the first bolt 42, increasing the friction at one end of the first bolt 42. By fixing several anti-slip blocks 46 to one end of the first bolt 42, the friction between the first bolt 42 and the operator is increased, making it easier for the operator to rotate the first bolt 42. A rubber sleeve 47 is provided on one side of the connecting plate 43, covering and protecting the corners of the connecting plate 43. By fixing the rubber sleeve 47 to the connecting plate 43, the operator can better grip the connecting plate 43 for movement, preventing injury to the operator from the corners of the connecting plate 43.

[0035] Figures 1 to 4The limiting device 5 shown includes a first limiting block 51, a slide rail 52, a sliding block 53, a second limiting block 54, and a second bolt 55. The first limiting block 51 is located on the side of the cylinder 1 near the scale 44. The slide rail 52 is located on the side of the first limiting block 51. The sliding block 53 moves inside the slide rail 52 and drives the second limiting block 54 to the upper end of the scale 44. The second bolt 55 rotates inside the sliding block 53 and fixes the position of the sliding block 53 and the second limiting block 54. The first limiting block 51, fixed on the cylinder body 1, limits the scale 44 on one side of the cylinder body 1. The sliding block 53 inside the slide rail 52 fixed on one side of the first limiting block 51 is moved, causing the sliding block 53 to slide inside the slide rail 52. This causes the second limiting block 54 fixed on one side of the sliding block 53 to reach the upper end of the scale 44. Then, the second bolt 55 is rotated, causing the second bolt 55 to rotate inside the sliding block 53, with one end abutting against the slide rail 52, thus fixing the position of the sliding block 53 and the second limiting block 54. The second limiting block 54 then limits the upper end of the scale 44, making the movement of the scale 44 more stable. This allows the operator to better use the scale 44. By using the limiting device 5, the movement trajectory of the scale 44 can be restricted, making the scale 44 move more stably, thereby improving the effectiveness of the monitoring device 4.

[0036] Figures 1 to 4 A rubber pad 56 is provided on the side of the slide rail 52 near the second bolt 55. The rubber pad 56 increases the friction between the slide rail 52 and the second bolt 55. By fixing the rubber pad 56 to one side of the slide rail 52, the friction between the second bolt 55 and the slide rail 52 is increased, allowing the second bolt 55 to better abut and fix itself to the slide rail 52. A reinforcing plate 57 is provided inside the slide rail 52, and the reinforcing plate 57 penetrates the sliding block 53. By fixing the reinforcing plate 57 inside the slide rail 52 and slidingly connecting it to the sliding block 53, the connection strength between the sliding block 53 and the slide rail 52 is increased, preventing the slide rail 52 and the sliding block 53 from separating.

[0037] Working principle: When using the hydraulic cylinder, the hydraulic oil enters the cylinder 1 through the pipe 3 of the cylinder 1, which drives the piston 2 inside the cylinder 1 to move. At this time, the monitoring device (4) measures the stroke of the piston 2 through the scale 44, so that the operator can observe and monitor the stroke of the piston 2 in real time. After the hydraulic oil leaves the cylinder 1, the piston 2 is reset by the spring inside the cylinder 1. Before piston 2 moves, connecting plate 43 is inserted into square tube 41 fixed to piston 2. Then, the first bolt 42 is rotated so that it passes through square tube 41 and is threaded to connecting plate 43, thus fixing the position of connecting plate 43. Then, the scale 44 fixed on one side of connecting plate 43 is aligned with one side of cylinder body 1. When piston 2 moves in contact with or connects to an object, scale 44 will move with piston 2. The operator observes the scale 44 at the connection point between cylinder body 1 and piston 2 to obtain the stroke of piston 2. Real-time monitoring of piston 2 stroke is then achieved. By using monitoring device 4, the stroke of piston 2 can be measured, allowing the operator to monitor piston 2 stroke in real time. This facilitates piston 2 inside cylinder body 1 moving the object to the accurate position, thereby improving the performance of the hydraulic cylinder.

[0038] The first limiting block 51, fixed on the cylinder body 1, limits the scale 44 on one side of the cylinder body 1. The sliding block 53 inside the slide rail 52 fixed on one side of the first limiting block 51 is moved, causing the sliding block 53 to slide inside the slide rail 52. This causes the second limiting block 54 fixed on one side of the sliding block 53 to reach the upper end of the scale 44. Then, the second bolt 55 is rotated, causing the second bolt 55 to rotate inside the sliding block 53, with one end abutting against the slide rail 52, thus fixing the position of the sliding block 53 and the second limiting block 54. The second limiting block 54 then limits the upper end of the scale 44, making the movement of the scale 44 more stable. This allows the operator to better use the scale 44. By using the limiting device 5, the movement trajectory of the scale 44 can be restricted, making the scale 44 move more stably, thereby improving the effectiveness of the monitoring device 4.
