Description

Technical Field

[0001] This utility model relates to the technical field of vertical pressure and horizontal thrust tooling, specifically to a tooling for testing the vertical pressure and horizontal thrust of products. Background Technology

[0002] The vertical pressure and horizontal thrust fixture is used to test the vertical pressure and horizontal thrust of a product. It uses hydraulic principles and works with sensors and controllers to test the product, thereby enabling quantitative detection of the vertical pressure and horizontal thrust. When this vertical pressure and horizontal thrust fixture is used to load and push off the bearing pads of precision equipment during movement, the product qualification standard is that the rubber does not fall off or delaminate.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Common vertical pressure and horizontal thrust fixtures typically use hydraulically driven pressure blocks to test the vertical pressure of materials. However, the pressure blocks lack corresponding limiting structures during movement, which can cause positional deviations and affect the accuracy of the test. Utility Model Content

[0005] The purpose of this invention is to provide a tooling for testing the vertical pressure and horizontal thrust of products, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tooling for testing the vertical pressure and horizontal thrust of a product, including a base, a placement template fixedly connected to the top of the base, a push-off component provided on one side of the top of the placement template, guide columns fixedly connected around the other side of the top of the placement template, a fixing plate fixedly connected to the top of the guide columns, a second hydraulic cylinder provided on the top of the fixing plate, the second hydraulic cylinder being connected to a second oil pump, and the bottom of the second hydraulic cylinder being connected to a pressing component.

[0007] The second hydraulic cylinder includes a first hydraulic cylinder installed in the middle of one side of the top of the template. The first hydraulic cylinder is connected to a first oil pump. One side of the first hydraulic cylinder is connected to a first connecting plate. A first limiting rod is slidably connected around one side of the first connecting plate. A first spring is sleeved on the outside of the first limiting rod on one side of the first connecting plate. A push plate is fixedly connected to one side of the first limiting rod and the first spring.

[0008] The pressing assembly includes a second connecting plate installed at the bottom of the second hydraulic cylinder. A second limiting rod is slidably connected to the bottom center of the second connecting plate. A second spring is sleeved on the outside of the second limiting rod below the second connecting plate. A pressing block is fixedly connected to the bottom of the second limiting rod and the second spring.

[0009] The beneficial effects of this utility model are as follows: Through the design of the guide post, when the second connecting plate moves vertically, the limiting groove will slide outside the guide post, thereby ensuring the stability of the second connecting plate during movement and increasing the limiting property. This effectively avoids positional deviation of the lower pressure block, improves the accuracy of vertical pressure testing, and through the elastic deformation of the first and second springs, the horizontal thrust and vertical pressure can be buffered to a certain extent, effectively preventing rigid collision between the push plate, the lower pressure block and the product, thereby avoiding damage to the product and ensuring the quality of the product after testing.

[0010] To enable effective testing of vertical pressure and horizontal thrust:

[0011] The configuration is further defined as follows: a first piston rod is provided inside one side of the first hydraulic cylinder, and the first piston rod forms a transmission structure through the cooperation of the first hydraulic cylinder and the first oil pump; and a second piston rod is provided inside the bottom of the second hydraulic cylinder, and the second piston rod forms a transmission structure through the cooperation of the second hydraulic cylinder and the second oil pump.

[0012] By adopting the above technical solution, the first piston rod can push the first connecting plate to move horizontally, thereby testing the horizontal thrust of the product through the push plate. Furthermore, the push plate can drive the second connecting plate to move vertically, thereby testing the vertical pressure of the product through the pressure block, thus increasing the effectiveness of the test.

[0013] To achieve a certain degree of buffering of horizontal thrust:

[0014] Further configuration: a first sliding groove with the same external dimensions and structure as the first limiting rod is provided around one side of the first connecting plate, and the first spring and the push plate form an elastic structure, and a first limiting plate is fixedly connected to one side of the first limiting rod.

[0015] By adopting the above technical solution, the elastic deformation of the first spring allows the first limiting rod to slide within the first sliding groove, thereby effectively preventing the push plate from rigidly colliding with the product. This also provides some buffering for the horizontal thrust, preventing damage to the product. Furthermore, the first limiting plate increases the limiting function of the first limiting rod, preventing it from falling off.

[0016] To achieve stability of the pressure block during vertical movement:

[0017] Further configuration: The top perimeter of the second connecting plate is provided with limiting grooves that match the external dimensions and structure of the guide post.

[0018] By adopting the above technical solution, when the second connecting plate moves vertically, the limiting groove will slide outside the guide post, thereby ensuring the stability of the second connecting plate during movement, increasing the limiting effect, effectively avoiding positional deviation of the lower pressure block, and improving the accuracy of vertical pressure testing.

[0019] To achieve a certain degree of buffering against vertical pressure:

[0020] Further configuration: a second sliding groove with the same external dimensions as the second limiting rod is evenly provided in the top center of the second connecting plate, and the second spring and the lower pressure block form an elastic structure, and a second limiting plate is fixedly connected to the top of the second limiting rod.

[0021] By adopting the above technical solution, the elastic deformation of the second spring allows the second limiting rod to slide within the second sliding groove, thereby effectively preventing the lower pressure block from rigidly colliding with the product. This provides a certain buffer against vertical pressure, preventing damage to the product. Furthermore, the second limiting plate increases the limiting function of the second limiting rod, preventing it from falling off.

[0022] To achieve accuracy in horizontal thrust and vertical pressure:

[0023] Further configuration: a thrust sensor is installed inside the push plate, a pressure sensor is installed inside the pressure block, and a controller is provided at the bottom of the placement template. The thrust sensor is connected in series with the first oil pump, and the pressure sensor is connected in series with the second oil pump.

[0024] By adopting the above technical solution, the vertical pressure value is collected by the pressure sensor and transmitted to the controller via wireless signal transmission. The controller then shuts down the second oil pump, ensuring that the vertical pressure remains at that value. Similarly, the horizontal thrust value is collected by the thrust sensor and transmitted to the controller via wireless signal transmission. The controller then shuts down the first oil pump, ensuring that the horizontal thrust remains at that value. This ensures the accuracy of the horizontal thrust and vertical pressure values.

[0025] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0033] The second hydraulic cylinder 6 includes a first hydraulic cylinder 301 installed in the middle of one side of the top of the placement template 2. The first hydraulic cylinder 301 is connected to the first oil pump 302. One side of the first hydraulic cylinder 301 is connected to the first connecting plate 303. A first limiting rod 304 is slidably connected around one side of the first connecting plate 303. A first spring 305 is sleeved on the outside of the first limiting rod 304 on one side of the first connecting plate 303. A push-off plate 306 is fixedly connected to one side of the first limiting rod 304 and the first spring 305.

[0034] The pressing assembly 8 includes a second connecting plate 801 installed at the bottom of the second hydraulic cylinder 6. A second limiting rod 802 is slidably connected to the bottom center of the second connecting plate 801. A second spring 803 is sleeved on the outside of the second limiting rod 802 below the second connecting plate 801. A pressing block 804 is fixedly connected to the bottom of the second limiting rod 802 and the second spring 803.

[0035] In this embodiment, as Figure 1 and Figure 2 As shown, a first piston rod is provided inside one side of the first hydraulic cylinder 301, and the first piston rod forms a transmission structure through the cooperation of the first hydraulic cylinder 301 and the first oil pump 302. A second piston rod is provided inside the bottom of the second hydraulic cylinder 6, and the second piston rod forms a transmission structure through the cooperation of the second hydraulic cylinder 6 and the second oil pump 7.

[0036] In this embodiment, as Figure 1 and Figure 2 As shown, a first sliding groove with the same external dimensions and structure as the first limiting rod 304 is provided around one side of the first connecting plate 303, and the first spring 305 and the push plate 306 form an elastic structure, and a first limiting disc is fixedly connected to one side of the first limiting rod 304.

[0037] In this embodiment, as Figure 1 and Figure 3 As shown, the top periphery of the second connecting plate 801 is provided with limiting grooves that are consistent with the external dimensions and structure of the guide post 4.

[0038] In this embodiment, as Figure 1 and Figure 3 As shown, the top center of the second connecting plate 801 is uniformly provided with a second sliding groove that matches the external dimensions of the second limiting rod 802, and the second spring 803 and the lower pressing block 804 form an elastic structure, and the top of the second limiting rod 802 is fixedly connected with a second limiting plate.

[0039] In this embodiment, as Figure 1 . Figure 2 , Figure 3 and Figure 4 As shown, a thrust sensor is installed inside the push plate 306, and a pressure sensor is installed inside the pressure block 804. A controller is provided at the bottom of the placement template 2. The thrust sensor is connected in series with the first oil pump 302, and the pressure sensor is connected in series with the second oil pump 7.

[0040] The testing fixture for the vertical pressure and horizontal thrust of the product operates as follows:

[0041] First, place the product on top of the placement template 2 and below the lower pressure block 804. Then, start the second oil pump 7 (model: PV063R1K1T1NMMC) to allow hydraulic oil to enter the second hydraulic cylinder 6 (model: HSG-KF100 / 63-500). This causes the second piston rod to extend, moving the second connecting plate 801 vertically downwards. The limiting groove slides outside the guide post 4, providing a limiting function. When the lower pressure block 804 is in contact with the top of the product... As the pressure continues to decrease, the second spring 803 undergoes elastic deformation, causing the second limit rod 802 to slide inside the second sliding groove. This buffers the pressure and prevents rigid collisions with the product. The pressure sensor (model: BMP280) then collects the values ​​and transmits them wirelessly to the controller (model: STC89C52). Based on the controller's preset values, the second oil pump 7 is shut off. At this point, the vertical pressure is the required value, and then the first oil pump 302 (model: PV063R1) is activated. The hydraulic oil enters the first hydraulic cylinder 301 (model: HSG-KF100 / 63-500) via K1 T1NMMC, thereby extending the first piston rod and moving the first connecting plate 303 horizontally to the right. When the push plate 306 is in contact with one side of the product, it continues to push. At this time, the first spring 305 will undergo elastic deformation, causing the first limit rod 304 to slide inside the first sliding groove, thus buffering the thrust and avoiding rigid collision with the product. Then, the thrust sensor (model: BK-2B-500) collects the values ​​and transmits them to the controller via wireless signal. Based on the controller's preset value, the first oil pump 302 is shut off. At this time, the horizontal thrust is the required value, thus performing vertical pressure and horizontal thrust tests on the product.
