Abstract
Description
Technical Field
[0001] This utility model relates to the field of adjustable support technology, and in particular to a resin grinding wheel testing auxiliary device. Background Technology
[0002] The resin grinding wheel testing auxiliary device is a special equipment used to assist in the testing of the performance of resin grinding wheels. It mainly focuses on the standardized testing of key indicators of resin grinding wheels in actual use.
[0003] For example, publication number CN222222177U discloses an auxiliary device for testing resin grinding wheels, belonging to the field of resin grinding wheel testing technology. It includes a fixed platform and a chassis. The front of the chassis has a through slot, and the back of the chassis is threadedly connected to a first threaded rod. One end of the first threaded rod is fixedly connected to a stop block. In this invention, the second threaded rod presses and fixes the reinforcing bar inside the through hole through thread displacement, thereby fixing the reinforcing bar to the fixed block. Then, the grinding machine is started to rotate the resin grinding wheel being tested. Finally, the second handle is grasped and rotated upwards. The second handle drives the connecting rod to rotate, which in turn drives the reinforcing bar on the fixed block to rotate. The reinforcing bar approaches the resin grinding wheel and is cut during the rotation. During the process, the grinding machine and the reinforcing bar are fixed as a single unit, and the cutting operation can be achieved simply by rotating the second handle, eliminating the need for manual handling of any component, thus saving manpower.
[0004] In the aforementioned patent, by placing the second handle behind the connecting rod, the rotation operation of the second handle can be moved away from the position where the grinder cuts the rebar. However, the problem still exists: it is difficult to accurately control the rebar feed speed by manually operating the rebar position, which can easily lead to uneven stress on the rebar, affecting the test results or damaging the resin grinding wheel. Therefore, a resin grinding wheel testing auxiliary device is needed to ensure that the rebar approaches the resin grinding wheel at a uniform speed and avoid safety accidents caused by vibration due to human operation.

By means of a fixing device, the problem of traditional resin grinding wheel testing auxiliary devices having few external force points, which makes them inconvenient to move, is solved.

[0033] The specific settings and functions of the adjustment device 2 and the fixing device 3 will be described in detail below.
[0034] Reference Figure 2 and Figure 3 As shown in this embodiment: the adjusting device 2 includes a second vibration-resistant cylinder 201. One side of the second vibration-resistant cylinder 201 is fixedly connected to the worktable 1. An adjusting plate 202 is fixedly connected to the output end of the second vibration-resistant cylinder 201. A support hole block 207 is fixedly connected to one side of the adjusting plate 202. A support block 203 is fixedly connected to one side of the adjusting plate 202. An internal threaded ring 204 is fixedly connected to one side of the support block 203. A bolt 205 is threaded into the internal thread of the internal threaded ring 204. One end of the bolt 205 is fixedly connected to a stop cylinder 206. This achieves the effect that when the second vibration-resistant cylinder 201 is activated, the output end drives the adjusting plate 202 to move, thereby adjusting the position of the support block 203 and the support hole block 207. Two sliders 209 are fixedly connected to one side of the adjusting plate 202. This achieves the effect that the sliders 209 are fixed on the adjusting plate 202. A slide rail 208 is slidably connected inside the slider 209. One side of the two slide rails 208 is fixedly connected to the worktable 1. This achieves the effect of slider 209 sliding on slide rail 208. Two through rods 210 are fixedly connected to the inner side of adjusting plate 202. This achieves the effect of through rods 210 being fixed to adjusting plate 202. Limiting rods 211 are slidably connected inside through rods 210, and the two ends of the two limiting rods 211 are fixedly connected to worktable 1. This achieves the effect of through rods 210 sliding on limiting rods 211.
[0035] Reference Figure 4As shown in this embodiment: the fixing device 3 includes a fixing plate 31, one side of which is fixedly connected to the worktable 1, and two telescopic rods 32 are fixedly connected to one side of the fixing plate 31. This achieves the effect of fixing the telescopic rods 32 to the fixing plate 31, and fixing the fixing plate 31 to the worktable 1. A connecting plate 34 is fixedly connected to the output ends of the two telescopic rods 32, and a round rod 36 is fixedly connected to one side of the connecting plate 34. The arc surface of the round rod 36 is slidably connected to the fixing plate 31. This achieves the effect of the connecting plate 34 moving to extend the telescopic rods 32 and move the round rod 36, allowing the round rod 36 to slide on the fixing plate 31, preventing the connecting plate 34 from shifting position during movement. Springs 33 are fitted onto the arc surface of the telescopic rods 32, and the two ends of the two springs 33 are fixedly connected to the fixing plate 31 and the connecting plate 34 respectively. This achieves the effect of the springs 33 providing a certain elastic force to assist the movement of the telescopic rods 32 during extension or retraction. A handle 35 is fixedly connected to one side of the connecting plate 34. The handle 35 has a U-shaped cross-section. This achieves the effect of fixing the handle 35 to the connecting plate 34.
[0036] Working Principle: When testing the resin grinding wheel, the operator first installs the resin grinding wheel to be tested onto the grinding machine spindle via the adjustment device 2. Then, the grinding machine is placed inside the housing 4, ensuring the resin grinding wheel is exposed through the slot on the front of the housing 4. The first vibration-resistant cylinder 5 is activated, and its output end applies uniform extrusion force to the outside of the grinding machine through linear motion. This, combined with the inner wall of the housing 4, firmly fixes the grinding machine inside, preventing displacement or vibration during testing. The reinforcing bar to be tested is inserted into the support hole block 207. Rotating the bolt 205 causes it to move on the internal thread ring 204, moving the abutment cylinder 206. The abutment cylinder 206, through its cooperation with the support block 203, gradually applies pressure towards the reinforcing bar until it is tightly pressed against the support hole block 207, achieving rigid fixation of the reinforcing bar. This process utilizes the self-locking characteristic of the threaded drive to ensure the reinforcing bar does not loosen during cutting. The grinding machine is then started. The resin grinding wheel rotates at a set speed at high speed. Then, the second vibration-resistant cylinder 201 is activated. Its output end pushes the adjusting plate 202 to move linearly in the horizontal direction, causing the steel bar fixed to the adjusting plate 202 to move, so that the steel bar is gradually fed towards the resin grinding wheel. By adjusting the air intake flow of the second vibration-resistant cylinder 201 (such as by using a throttle valve or proportional valve), the feeding speed of the steel bar is precisely controlled, avoiding speed fluctuations caused by manual operation. During the movement of the adjusting plate 202, the slider 209 slides synchronously along the slide rail 208, and at the same time, the through rod 210 slides along the limit rod 211, forming a double limit structure, which effectively prevents the adjusting plate 202 from deviating or jamming, and ensures the straightness and stability of the steel bar feeding trajectory. Through the adjusting device 2, the problem of traditional resin grinding wheel testing auxiliary devices, which rely on manual steel bar position operation, is difficult to accurately control the steel bar feeding speed, which can easily lead to uneven stress on the steel bar, affecting the test results or damaging the resin grinding wheel.
[0037] With the fixing device 3, when the device needs to be moved, the operator first holds the handle 35 installed on the side of the workbench 1 and continuously applies a pulling force away from the workbench 1 in the horizontal direction. This pulling force is transmitted to the connecting plate 34, which drives the output end of the telescopic rod 32 connected to the connecting plate 34 to extend outward, while the spring 33 is in a stretched state. When the telescopic rod 32 reaches its maximum extension stroke, the workbench 1 can be lifted. At this time, the device is in a transportable state. During the process of applying the pulling force to move the connecting plate 34, the round rod 36 fixed to the connecting plate 34 slides on the fixing plate 31 to prevent the connecting plate 34 from shifting its position when moving. With the fixing device 3, the problem of traditional resin grinding wheel testing auxiliary devices having few external force points, which makes them inconvenient to move, is solved.
