Description

Technical Field

[0001] This utility model relates to the field of grease processing technology, specifically a grease shear tester. Background Technology

[0002] A grease shear tester is a specialized device used to evaluate the performance of grease. It mainly uses high-speed extrusion or grinding to cause the material to collide and disperse violently under strong impact. Under this mixing and shearing action, a more uniform and fine grease product can be obtained.

[0003] Currently, the main method is to install the shearing cylinder on the testing machine, and drive the piston on the shearing cylinder to quickly shear and wet the material through the driving of the testing machine.

[0004] However, since the piston on the shearing cylinder is exposed to the air, when the piston moves up and down rapidly, it causes the surrounding air to flow, creating a local negative pressure. This causes dust, particles, and other impurities in the air to be adsorbed onto the surface of the piston rod. These impurities enter the cylinder along with the piston rod and mix with the grease. This not only affects the physical and chemical properties of the grease but may also scratch the piston and the inner wall of the cylinder, increasing friction and wear, thereby reducing the service life of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a grease shear tester to solve the problem mentioned in the background art, whereby dust is easily carried into the cylinder along with the piston rod during rapid lifting and lowering of the piston on the shear cylinder, increasing friction and wear, and thus reducing the service life of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grease shear tester, comprising a tester base disposed on the grease shear tester, wherein a piston portion is slidably connected to the top of the tester base; and further comprising;

[0007] A protective assembly is disposed between the tester base and the piston section. The protective assembly is used to protect the tester base and the piston section. The protective assembly includes a protective sleeve that is fitted onto the outer peripheral wall of the piston section. A fixing rod is fixedly connected to the top of the tester base and the bottom of the piston section. The fixing rod is inserted into the upper and lower ends of the protective sleeve.

The assembly assembly includes a movable component that is inserted into the side wall of the piston portion. A retaining rod is provided on the inner wall of the piston portion and is engaged with the upper and lower sides of the movable component.

[0009] Preferably, the protective assembly further includes a connecting plate, which is fixedly connected to the upper and lower ends of the protective sleeve. A fixing hole is provided on the top of the connecting plate, and the end of the fixing rod passes through the fixing hole.

[0010] Preferably, the fixing rod has locking blocks extending through both sides, and the locking blocks are engaged with the top of the connecting plate.

[0011] Preferably, a limiting plate is fixedly connected to the end of the card block, and the limiting plate is slidably connected inside the fixing rod.

[0012] Preferably, a return spring is fixedly connected to the side wall of the limiting plate, and the return spring is fixedly installed inside the fixing rod.

[0013] Preferably, the assembly further includes a slider, which is fixedly connected to the upper and lower sides of the movable part, and the inner wall of the piston part is provided with a groove, and the slider is slidably connected inside the groove.

[0014] Preferably, the locking rod penetrates the side wall of the slide groove and is inserted between the movable parts.

[0015] Preferably, a connector is fixedly connected to the end of the lever, the connector is slidably connected to the inside of the piston part, and a lead screw is rotatably connected to the end of the connector, the lead screw being threaded to the side wall of the piston part.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] like Figure 1 - Figure 5 As shown, this application provides a grease shear tester, including a tester base 1 disposed on the grease shear tester, and a piston 2 slidably connected to the top of the tester base 1; and also includes;

[0027] Specifically, such as Figure 2 As shown, a protective component 3 is provided between the tester base 1 and the piston part 2. The protective component 3 is used to protect the tester base 1 and the piston part 2. The protective component 3 includes a protective sleeve 301, which is sleeved on the outer peripheral wall of the piston part 2. A fixing rod 303 is fixedly connected to the top of the tester base 1 and the bottom of the piston part 2. The fixing rod 303 is inserted into the upper and lower ends of the protective sleeve 301. By providing a protective component 3 between the tester base 1 and the piston part 2, and by sleeved the protective sleeve 301 on the protective component 3 between the tester base 1 and the piston part 2, the piston rod on the piston part 2 can be protected, thereby improving the service life of the tester base 1 and the piston part 2.

[0028] The upper and lower ends of the protective sleeve 301 are fixedly connected to the connecting plate 302. The top of the connecting plate 302 is provided with a fixing hole 3031. The end of the fixing rod 303 passes through the fixing hole 3031. The protective sleeve 301 can be made of an elastic material to facilitate retraction according to the lifting and lowering of the piston part 2.

[0029] Specifically, such as Figure 3 As shown, locking blocks 304 extend through both sides of the fixing rod 303. The locking blocks 304 are engaged with the top of the connecting plate 302. A limiting plate 305 is fixedly connected to the end of the locking blocks 304. The limiting plate 305 is slidably connected inside the fixing rod 303. A return spring 306 is fixedly connected to the side wall of the limiting plate 305. The return spring 306 is fixedly installed inside the fixing rod 303. By squeezing the two sets of locking blocks 304, the connecting plate 302 on the protective sleeve 301 can be sleeved onto the fixing rod 303. When the locking blocks 304 are released, the elastic force of the return spring 306 can reset the two sets of locking blocks 304, and the locking blocks 304 will then engage with the top of the connecting plate 302 for fixation.

[0030] Specifically, such as Figure 4 As shown, the piston part 2 has an assembly assembly 4 on its side wall. The assembly assembly 4 is used to assemble the piston part 2. The assembly assembly 4 includes a movable part 401, which is inserted into the side wall of the piston part 2. The piston part 2 has a locking rod 403 on its inner wall, which is engaged with the upper and lower sides of the movable part 401. By setting the assembly assembly 4 on the side wall of the piston part 2, the piston part 2 can be quickly fitted onto the tester for use by moving the movable part 401 on the assembly assembly 4, thus improving the assembly efficiency.

[0031] Specifically, such as Figure 5 As shown, sliding members 402 are fixedly connected to the upper and lower sides of the movable member 401. A groove 4021 is provided on the inner wall of the piston part 2. The sliding member 402 is slidably connected inside the groove 4021. The locking rod 403 passes through the side wall of the groove 4021. The locking rod 403 is inserted between the movable members 401, so that the movable member 401 can be fixed.

[0032] The end of the locking rod 403 is fixedly connected to the connector 404, which is slidably connected inside the piston part 2. The end of the connector 404 is rotatably connected to the lead screw 405, which is threaded to the side wall of the piston part 2. By rotating the lead screw 405 outward, the locking rod 403 can be driven to retract inside the piston part 2, so that the movable part 401 can be pulled out for assembly.

[0033] The specific steps of this solution are as follows: First, the protective sleeve 301 is fitted between the tester base 1 and the piston part 2, and the two sets of locking blocks 304 are pinched together. The connecting plate 302 on the protective sleeve 301 is fitted onto the fixing rod 303. After releasing the locking blocks 304, the two sets of locking blocks 304 can be reset by the elastic force of the reset spring 306. At this time, the locking blocks 304 will be locked onto the top of the connecting plate 302 for fixation. Next, the piston part 2 is slidably assembled onto the cutting tester, and the sliding part 402 on the movable part 401 is inserted into the slide groove 4021. By rotating the screw 405 inward, the locking rod 403 can be driven to be inserted between the movable parts 401 to fix the movable parts 401. Finally, the cutting tester is driven to drive the piston part 2 to lift and shear.
