Description

Technical Field

[0001] This utility model relates to the field of testing machine technology, and in particular to a safety protection device for press-type testing machines. Background Technology

[0002] Press press testing machines are used to test the compressive strength of workpieces. They provide stable pressure through hydraulic or pneumatic systems. Their structure includes a frame, pressure application mechanism, and detection sensors. They can precisely control the pressure and duration. They are also equipped with sensors so that the press press testing machine can only be started when the operator leaves the sensing area.

[0003] The above-mentioned and existing technologies have the following defects: In the current production of printed circuit boards, electrical testing is an indispensable or irreplaceable process. Due to the large number of part numbers of PCB boards, the frequent change of fixtures and the need to perform open and short circuit tests on all circuits, the number of tests increases. This makes it easy for workers to be negligent after setting up the fixture and fail to remove the safety bar to start the test, which causes wear on the guide pillars of the machine.

[0004] Therefore, a safety protection device for pressure testing machines is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that if workers neglect to remove the safety bar after the fixture is completed and start the test, it will cause wear to the guide column of the machine. Therefore, a safety protection device for press-type testing machines is proposed.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a safety protection device for a pressure press testing machine, comprising a testing machine body, two sensors fixedly installed on the surface of the testing machine body, a storage block fixedly installed on the surface of the testing machine body, a pressure press storage rod slidably connected inside the storage block, two push rods slidably inserted inside the storage block, the surfaces of the push rods abutting against the pressure press safety rod, and a bearing plate fixedly installed on the lower surface of the push rods. The original single magnetic spring design of the safety door of the testing machine is changed to double micro-switch protection, and connected in series with the pressure press safety rod signal. At the same time, the overall protection range of the sensor light curtain is extended to the entire operating area. When using the testing machine, after the fixture is set up, the safety rod must be removed and placed in the designated storage block, the back door closed, and it must be ensured that there are no foreign objects in the light curtain of the testing area before both hands can be used to start the normal test.

[0007] The effect achieved by the above-mentioned components is that when using press-type testing machines, the press safety bar can be placed in the designated placement area, avoiding the problem of wear on the machine guide column caused by the operator failing to remove the safety bar after setting up the fixture and starting the test due to negligence, and effectively reducing the wear of the press lifting guide column.

[0008] Preferably, a support rod is fixedly inserted inside the two support plates, and a limit rope is fixedly installed on the surface of the support rod, with the surface of the limit rope being fixedly connected to the storage block.

[0009] The effect achieved by the above components is that the limiting rope can restrict the top rod from sliding out of the storage block with the help of the bearing rod and the bearing plate, thus achieving the effect of restricting the top rod from sliding out of the storage block.

[0010] Preferably, the arc surfaces of the two top rods are fitted with springs, and the two ends of the springs are fixedly connected to the storage block and the support plate, respectively.

[0011] The effect achieved by the above components is that the spring can drive the support plate to slide downwards, and the sliding of the support plate drives the push rod, thus achieving the effect of driving the push rod to slide downwards.

[0012] Preferably, each of the two sensors has two cleaning pads slidably connected to its surface, and each cleaning pad has a hanging bracket slidably connected to its interior. The four hanging brackets are arranged in pairs, and each pair of hanging brackets has a sleeve fixedly installed on its surface. A support cylinder is fixedly fitted onto the surface of each hanging bracket, and the surface of the support cylinder abuts against the cleaning pad.

[0013] The effect achieved by the above components is as follows: the sliding block slides while the cleaning pad slides with the help of the bracket, and during the sliding process, the cleaning pad cleans the sensing part of the sensor.

[0014] Preferably, each of the four hangers has a fixed cylinder threadedly connected to its surface, and the surface of the fixed cylinder abuts against the cleaning pad.

[0015] The effect achieved by the above components is as follows: when the fixed cylinder is rotated, the fixed cylinder moves downward with the help of the screw thread. After the fixed cylinder moves a certain distance, the surface of the fixed cylinder presses the cleaning pad, and at this time the cleaning pad is fixed on the sleeve block, thus achieving the effect of fixing the cleaning pad and the sleeve block.

[0016] Preferably, an operating frame is fixedly installed on the surface of both of the sleeve blocks, and the cross-section of the operating frame is "U" shaped.

[0017] The above components achieve the following effect: the operator can slide the sleeve up and down with the help of the operating frame. As the sleeve slides, it also drives the cleaning pad to slide, thus achieving the effect of assisting the sliding of the cleaning pad.

[0018] Preferably, two top pads are fixedly installed on the surface of the testing machine body. The top pads are elastic pads, and the size of the top pads is adapted to the size of the cleaning pad.

[0019] The effect achieved by the above components is that when the sensing part of the cleaning sensor is not needed, the cleaning pad can be suspended with the help of the top pad, thus achieving the effect of storing the cleaning pad.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In this invention, when using a press-type testing machine, the press safety bar can be placed in a designated area to avoid the problem of wear on the machine guide column caused by the operator failing to remove the safety bar after setting up the fixture and starting the test. This effectively reduces the wear on the press lifting guide column. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] like Figure 1-5As shown, this utility model provides a safety protection device for a press-type testing machine, including a testing machine body 1. Two sensors 2 are fixedly installed on the surface of the testing machine body 1. A storage block 3 is fixedly installed on the surface of the testing machine body 1. A press storage rod is slidably connected inside the storage block 3. Two push rods 5 are slidably inserted inside the storage block 3. The surface of the push rods 5 abuts against the press safety rod 4. A bearing plate 7 is fixedly installed on the lower surface of the push rods 5. A bearing rod 8 is fixedly inserted inside the two bearing plates 7. A limit rope 9 is fixedly installed on the surface of the bearing rod 8. The surface of the limit rope 9 is fixedly connected to the storage block 3. 9. The support rods 8 and 7 can be used to restrict the top rod 5 from sliding out of the storage block 3, thus achieving the effect of restricting the top rod 5 from sliding out of the storage block 3. The arc surfaces of the two top rods 5 are fitted with springs 6, and the two ends of the springs 6 are fixedly connected to the storage block 3 and the support plate 7 respectively. The springs 6 can drive the support plate 7 to slide downward. As the support plate 7 slides, it drives the top rods 5, thus achieving the effect of driving the top rods 5 to slide downward. The surfaces of the two sensors 2 are slidably connected to two cleaning pads 10. The interior of the cleaning pads 10 is slidably connected to a bracket 12. The four brackets 12 are arranged in pairs, and the surfaces of the two sets of brackets 12 are fixedly installed with sleeves 11. A support cylinder 15 is fixedly fitted onto the surface of the bracket 12. The surface of the support cylinder 15 abuts against the cleaning pad 10. A sliding block 11 slides, and as the block 11 slides, the cleaning pad 10 slides with the help of the bracket 12. During the sliding process, the cleaning pad 10 clears the sensing part of the sensor 2. Each of the four brackets 12 has a fixed cylinder 13 threadedly connected to its surface. The surface of the fixed cylinder 13 abuts against the cleaning pad 10. When the fixed cylinder 13 is rotated, it moves downwards with the help of the threads. After the fixed cylinder 13 has moved a certain distance, its surface presses against the cleaning pad 10, thus fixing the cleaning pad 10 onto the block 11, achieving a secure fit. The cleaning pad 10 and the sleeve block 11 are fixedly mounted on the surface of both sleeve blocks 11. The cross-section of the operating frame 14 is "U" shaped. The operator can slide the sleeve block 11 up and down with the help of the operating frame 14. When the sleeve block 11 slides, it drives the cleaning pad 10 to slide, thus achieving the effect of assisting the sliding of the cleaning pad 10. Two top pads 16 are fixedly mounted on the surface of the test machine body 1. The top pads 16 are elastic pads. The size of the top pads 16 is adapted to the size of the cleaning pad 10. When the sensing part of the cleaning sensor 2 is not needed, the cleaning pad 10 can be suspended with the help of the top pads 16, thus achieving the effect of storing the cleaning pad 10.

[0031] The overall working principle is as follows: when using a press-type testing machine, the press safety rod 4 can be placed inside the storage block 3. When it is necessary to change the fixture, the support plate 7 is slid upward with the support rod 8. As the support plate 7 slides, the push rod 5 slides. As the push rod 5 slides, the press safety rod 4 slides. After the press safety rod 4 slides a certain distance, it moves out of the storage block 3. At this time, the press safety rod 4 can be used to change the fixture.
