Description

Technical Field

[0001] The utility model relates to the technical field of instrument testing, in particular to a piston type press for instrument testing. Background Art

[0002] A piston type press is a device for testing the compressive resistance of an instrument by extrusion. When using the press to detect the compressive resistance of the instrument, the instrument is manually placed on the top of the bottom plate, and the force applied by the cylinder is set through the operation panel, so that the piston rod drives the extrusion plate to slide out of the cylinder, so that the extrusion plate can be pressed on the instrument. By slowly increasing the applied force, when the instrument is damaged, the compressive resistance of the instrument can be intuitively understood through the data displayed on the operation panel.

[0003] The inventor found in daily work that the press still has at least the following problems: when using the press to detect the compressive resistance of the instrument, the instrument is manually placed on the top of the bottom plate, and the force applied by the cylinder is set through the operation panel, so that the piston rod drives the extrusion plate to slide out of the cylinder, so that the extrusion plate can be pressed on the instrument. By slowly increasing the applied force, when the instrument is damaged, the compressive resistance of the instrument may be obtained. However, in the actual use process, when the instrument is damaged, fragments may fly everywhere, and the fragments may splash on the cylinder, which may cause damage to the piston type press. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and a piston type press for instrument testing is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a piston type press for instrument testing, including a bottom plate, a support frame is fixedly connected to the top of the bottom plate, a cylinder is arranged on the top of the support frame, a piston rod is arranged inside the cylinder, an extrusion plate is fixedly connected to the bottom of the piston rod, an operation panel is arranged on the top of the bottom plate, a protection device is arranged on one side of the piston rod, a limiting device is arranged on the top of the bottom plate, the protection device includes a connecting plate, the connecting plate is arranged on the surface of the piston rod, an elastic cover is fixedly connected to the bottom of the connecting plate, and a support frame is fixedly connected to the bottom of the elastic cover.

[0006] The effects achieved by the above components are as follows: when using the protection device, the connecting plate is arranged on the surface of the piston rod. When the extrusion plate presses the instrument, the support frame is arranged on the bottom plate, so that the elastic cover covers the instrument, which can avoid the fragments flying everywhere to a certain extent, and thus avoid the fragments damaging the cylinder to a certain extent.

[0007] Preferably, sliding grooves are formed on both sides of the support frame. Both the connecting plate and the support frame are slidably connected to the inner wall of the sliding groove. A damping rod is fixedly connected to the top of the support frame. The top of the damping rod and the bottom of the connecting plate are fixedly connected. A first spring is sleeved on the surface of the damping rod. One end of the first spring is fixedly connected to the top of the support frame, and the end of the first spring close to the damping rod is fixedly connected to the bottom of the connecting plate.

[0008] The effect achieved by the above components is that the support frame is extruded away from the connecting plate by the first spring, so that the support frame can be well arranged on the top of the bottom plate.

[0009] Preferably, a rubber ring is fixedly connected to the middle of the connecting plate, and the rubber ring is sleeved on the surface of the piston rod.

[0010] The effect achieved by the above components is that the connecting plate can be well sleeved on the surface of the piston rod through the rubber ring, which can limit the connecting plate on the surface of the piston rod to a certain extent.

[0011] Preferably, limiting grooves are uniformly formed on the top of the connecting plate. A sliding strip is slidably connected to the inner wall of the limiting groove. One end of the sliding strip is fixedly connected to a semi-circular plate, and the semi-circular plate is sleeved on the surface of the piston rod. A bolt is threadedly inserted through one side of the semi-circular plate, and the bolt is threadedly inserted into one side of the other semi-circular plate.

[0012] The effect achieved by the above components is to control the sliding strip to slide on the inner wall of the limiting groove, so that both semi-circular plates are sleeved on the surface of the piston rod. Then manually control the bolt to pass through the first semi-circular plate and insert it into one side of the other semi-circular plate, so that the connecting plate can be well limited on the surface of the piston rod.

[0013] Preferably, the limiting device includes an extrusion strip. A connecting groove is formed on the top of the bottom plate, and the inner wall of the connecting groove is slidably connected to the extrusion strip.

[0014] The effect achieved by the above components is that the limiting device can be well arranged on the top of the bottom plate through the connecting groove.

[0015] Preferably, a threaded rod is rotatably inserted into the inner wall of the connecting groove. The threaded rod is threadedly inserted through one side of the extrusion strip, and the thread direction on the surface of the threaded rod is opposite from the middle to both sides.

[0016] The effect achieved by the above components is to manually control the threaded rod to rotate. Since the thread direction on the surface of the threaded rod is opposite from the middle to both sides, the extrusion strip sleeved on the threaded rod can move relative to the surface of the threaded rod, so that the instrument can be well clamped on the top of the bottom plate by the two extrusion strips.

[0017] Preferably, a rectangular groove is formed on one side of the extrusion bar, a rectangular frame is slidably connected to the inner wall of the rectangular groove, a second spring is fixedly connected to one side of the inner wall of the rectangular groove, and one end of the second spring close to the rectangular groove is fixedly connected to one side of the rectangular frame.

[0018] The effect achieved by the above components is that the rectangular frame is pulled towards the middle of the extrusion bar by the second spring, so that the instrument can be restricted to the middle of the bottom plate by the two rectangular frames, and thus the instrument can be arranged exactly in the middle of the bottom of the extrusion plate.

[0019] Preferably, a rectangular rod is slidably connected to the inner wall of the rectangular frame, a third spring is fixedly connected to one side of the inner wall of the rectangular frame, one end of the third spring close to the rectangular frame is fixedly connected to one end of the rectangular rod, and the rectangular rod is slidably connected to the inner wall of the rectangular groove formed on the other side of the other extrusion bar.

[0020] The effect achieved by the above components is that the rectangular rod is extruded away from the rectangular frame by the third spring, so that the rectangular frame and the rectangular rod can be well restricted to slide on the inner wall of the rectangular groove.

[0021] In the present utility model, by providing a protection device, when using the protection device, the connecting plate is arranged on the surface of the piston rod. When the extrusion plate extrudes the instrument, the support frame is arranged on the bottom plate, so that the elastic cover covers the instrument, which can avoid the debris from splashing everywhere to a certain extent, and further avoid the debris from damaging the cylinder to a certain extent.

When using the press to detect the compressive resistance of the instrument, manually place the instrument on the top of the bottom plate 1, set the force applied by the cylinder 3 through the operation panel 6, so that the piston rod 4 drives the extrusion plate 5 to slide out of the cylinder 3, so that the extrusion plate 5 can be pressed on the instrument. By slowly increasing the applied force, when the instrument is damaged, the compressive resistance of the instrument can be intuitively understood through the data displayed on the operation panel 6.

[0028] Refer to Figure 2 and Figure 3, the protective device 7 includes a connecting plate 701 which is arranged on the surface of the piston rod 4. The bottom of the connecting plate 701 is fixedly connected with an elastic cover 702, and the bottom of the elastic cover 702 is fixedly connected with a support frame 703. When using the protective device 7, the connecting plate 701 is arranged on the surface of the piston rod 4. When the pressing plate 5 presses the instrument, the support frame 703 is arranged on the bottom plate 1, so that the elastic cover 702 covers the instrument, which can avoid debris from splashing everywhere to a certain extent, and thus avoid debris from damaging the cylinder 3 to a certain extent. Both sides of the support frame 2 are provided with sliding grooves 709. The connecting plate 701 and the support frame 703 are both slidably connected with the inner walls of the sliding grooves 709. The top of the support frame 703 is fixedly connected with a damping rod 710, and the top of the damping rod 710 and the bottom of the connecting plate 701 are fixedly connected. A first spring 711 is sleeved on the surface of the damping rod 710. One end of the first spring 711 is fixedly connected with the top of the support frame 703, and the end of the first spring 711 close to the damping rod 710 is fixedly connected with the bottom of the connecting plate 701. The support frame 703 is pushed away from the connecting plate 701 by the first spring 711, so that the support frame 703 can be well arranged on the top of the bottom plate 1. A rubber ring 704 is fixedly connected to the middle of the connecting plate 701, and the rubber ring 704 is sleeved on the surface of the piston rod 4. The connecting plate 701 can be well sleeved on the surface of the piston rod 4 through the rubber ring 704, which can limit the connecting plate 701 on the surface of the piston rod 4 to a certain extent. Limiting grooves 705 are evenly opened at the top of the connecting plate 701. A sliding bar 706 is slidably connected with the inner wall of the limiting groove 705. One end of the sliding bar 706 is fixedly connected with a semi-circular plate 707, and the semi-circular plate 707 is sleeved on the surface of the piston rod 4. A bolt 708 is threadedly inserted through one side of the semi-circular plate 707, and the bolt 708 is threadedly inserted into the other side of the other semi-circular plate 707. The sliding bar 706 is controlled to slide on the inner wall of the limiting groove 705, so that both semi-circular plates 707 are sleeved on the surface of the piston rod 4. Then, the bolt 708 is manually controlled to pass through the first semi-circular plate 707 and then inserted into the other side of the other semi-circular plate 707, so that the connecting plate 701 can be well limited on the surface of the piston rod 4.

[0029] Refer to Figure 4, the limiting device 8 includes a pressing strip 802. A connecting groove 801 is formed at the top of the bottom plate 1, and the inner wall of the connecting groove 801 is slidably connected to the pressing strip 802. Through the connecting groove 801, the limiting device 8 can be well arranged on the top of the bottom plate 1. A threaded rod 803 is rotatably inserted into the inner wall of the connecting groove 801, and the threaded rod 803 is threadedly inserted through one side of the pressing strip 802. The thread direction on the surface of the threaded rod 803 is opposite from the middle to both sides. Manually control the rotation of the threaded rod 803. Because the thread direction on the surface of the threaded rod 803 is opposite from the middle to both sides, the pressing strip 802 sleeved on the surface of the threaded rod 803 can move relatively on the surface of the threaded rod 803. Furthermore, the instrument can be well clamped on the top of the bottom plate 1 by the two pressing strips 802. A rectangular groove 807 is formed on one side of the pressing strip 802, and a rectangular frame 804 is slidably connected to the inner wall of the rectangular groove 807. One side of the inner wall of the rectangular groove 807 is fixedly connected to a second spring 808, and one end of the second spring 808 close to the rectangular groove 807 is fixedly connected to one side of the rectangular frame 804. The rectangular frame 804 is pulled towards the middle of the pressing strip 802 by the second spring 808. In this way, the instrument can be restricted to the middle of the bottom plate 1 by the two rectangular frames 804. In this way, the instrument can be arranged exactly in the middle of the bottom of the pressing plate 5. A rectangular rod 805 is slidably connected to the inner wall of the rectangular frame 804. One side of the inner wall of the rectangular frame 804 is fixedly connected to a third spring 806, and one end of the third spring 806 close to the rectangular frame 804 is fixedly connected to one end of the rectangular rod 805. The rectangular rod 805 is slidably connected to the inner wall of the rectangular groove 807 formed on the other side of the other pressing strip 802. The rectangular rod 805 is extruded away from the rectangular frame 804 by the third spring 806. In this way, the rectangular frame 804 and the rectangular rod 805 can be well restricted to slide on the inner wall of the rectangular groove 807.

[0030] Working principle: When using a press to detect the compressive resistance of an instrument, manually place the instrument on the top of the bottom plate 1, set the force applied by the cylinder 3 through the operation panel 6, so that the piston rod 4 drives the extrusion plate 5 to slide out of the cylinder 3, so that the extrusion plate 5 can be pressed against the instrument. By slowly increasing the applied force, when the instrument is damaged, the compressive resistance of the instrument can be intuitively understood through the data displayed on the operation panel 6. When using the protection device 7, the connecting plate 701 can be well sleeved on the surface of the piston rod 4 through the rubber ring 704, and then control the sliding bar 706 to slide on the inner wall of the limit groove 705, so that both semi-circular plates 707 are sleeved on the surface of the piston rod 4. Then manually control the bolt 708 to pass through the first semi-circular plate 707 and then insert it into one side of the other semi-circular plate 707, so that the connecting plate 701 can be well restricted on the surface of the piston rod 4. When the extrusion plate 5 presses the instrument, the support frame 703 is squeezed away from the connecting plate 701 through the first spring 711, so that the support frame 703 can be well arranged on the top of the bottom plate 1, so that the elastic cover 702 covers the instrument, which can avoid debris flying everywhere to a certain extent, and thus avoid debris damaging the cylinder 3 to a certain extent. When using the limit device 8, manually control the rotation of the threaded rod 803. Because the thread direction on the surface of the threaded rod 803 is opposite from the middle to both sides, the extrusion strips 802 sleeved on the surface of the threaded rod 803 can move relative to each other on the surface of the threaded rod 803, so that the instrument can be well clamped on the top of the bottom plate 1 through the two extrusion strips 802. The rectangular frame 804 is pulled towards the middle of the extrusion strip 802 through the second spring 808, so that the instrument can be restricted in the middle of the bottom plate 1 through the two rectangular frames 804, so that the instrument can be set exactly in the middle of the bottom of the extrusion plate 5.
