Description

Technical Field

[0001] The utility model relates to the technical field of production of lifting platform screws, in particular to a lifting platform screw manufacturing and grinding device. Background Art

[0002] A screw is a cylinder with spiral grooves cut on the outer surface or a cone with spiral grooves cut on the conical surface. Since the screw works under high temperature, certain corrosion, severe wear and high torque, the screw must be resistant to high temperature, wear, corrosion, high strength and have good cutting performance. Therefore, there are high requirements for the grinding and production of the screw.

[0003] In the prior art, an authorized patent with announcement number CN219684186U discloses a lifting platform screw manufacturing and grinding equipment, including a support column, a mounting plate fixedly connected to the surface of the support column, a workbench fixedly connected to the top of the support column, a fixing device arranged on the upper surface of the workbench, and also including a spray assembly. The utility model uses a water tank arranged on the mounting plate, a filter screen and a water pump arranged inside the water tank. Through the operation of the water pump, water inside the water inlet tank is sucked up, and through the cooperation of the water outlet pipe, the diversion pipe and the spray head, the screw in the grinding process can be sprayed, and metal debris can be adsorbed and settled to avoid splashing of debris. Through the drain outlet and the slope arranged on the workbench, the sewage and debris after spraying can fall into the water tank through the drain outlet, and be filtered through the filter screen, so as to realize the recycling of water resources. The filter screen is arranged to be detachable for easy cleaning.

[0004] However, the above technical solution still has the following shortcomings when it is actually used: during the grinding process of the screw, when the grinding surface of the screw needs to be replaced, the screw needs to be disassembled and assembled back and forth to replace the grinding surface, which is time-consuming and labor-intensive and affects the grinding efficiency. In this regard, we propose a lifting platform screw manufacturing and grinding equipment to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides a technical solution: a lifting platform screw manufacturing and grinding equipment, including:

[0021] A processing table 1, wherein four supporting legs 2 are fixedly mounted on the bottom wall of the processing table 1, fixed seats 3 are fixedly mounted on the top walls at both ends of the processing table 1, rotating seats 4 are rotatably mounted on the two fixed seats 3, a screw 5 is threadedly connected through a screw hole opened at the center of one of the rotating seats 4, a pressing plate 6 is mounted on the inner end of the screw 5, and a crank 7 is mounted on the outer end of the screw 5, locking mechanisms 8 are arranged on the two fixed seats 3, a driving mechanism 9 is arranged at the rear end of the processing table 1, two electric telescopic rods 10 are fixedly mounted on the driving mechanism 9, mounting plates 11 are fixedly mounted on the top ends of the two electric telescopic rods 10, a grinding mechanism 12 is arranged on the mounting plate 11, and the driving mechanism 9 and the grinding mechanism 12 are both publicly known technologies, and the specific structures are not described in detail.

[0022] The locking mechanism 8 includes a door frame 13, both ends of which are fixedly welded on the front side walls of the two fixed seats 3, and a stud 14 is threadedly connected to the door frame 13. A moving rod 15 is rotatably installed at the rear end of the stud 14. Connecting rods 16 are fixedly welded on the rear walls of both ends of the moving rod 15, and an arc-shaped pressing block 17 is fixedly welded on the connecting rod 16. The pressing surface of the arc-shaped pressing block 17 is provided with anti-slip grooves. When the stud 14 rotates forward, it can move backward on the door frame 13, thereby driving the moving rod 15 to move backward, driving the two arc-shaped pressing blocks 17 to be squeezed on the two rotating seats 4, thereby achieving the effect of synchronously limiting the two rotating seats 4.

[0023] A hand wheel 18 is fixedly mounted on the front end of the stud 14 , and two guide rods 19 are fixedly welded on the moving rod 15 , and the guide rods 19 are slidably connected to the door frame 13 . The hand wheel 18 facilitates the rotation of the stud 14 , and the guide rods 19 play a role in limiting and guiding the moving rod 15 .

[0024] A fixing plate 20 is fixedly welded on the bottom wall of the mounting plate 11, and a nozzle 21 is fixedly mounted on the fixing plate 20. The nozzle 21 is arranged on one side of the grinding mechanism 12. A water tank 22 is fixedly mounted on the bottom wall of the processing table 1, and a water pump is fixedly mounted in the water tank 22. A water pipe 23 is installed on the water pump of the water tank 22, and one end of the water pipe 23 away from the water tank 22 is fixedly mounted on the nozzle 21. The nozzle 21 is fixedly mounted on the mounting plate 11, so that the nozzle 21 can move with the grinding mechanism 12 when the mounting plate 11 moves, so as to flush the grinding debris and prevent the debris from flying.

[0025] An anti-skid pad 24 is fixedly mounted on one side wall of the rotating seat 4 and the pressing plate 6 which is away from the screw rod 5. The anti-skid pad 24 can prevent the screw rod of the installed lifting platform from being accidentally deflected.

[0026] The processing table 1 is provided with a drainage groove 25 , which is connected with the inner cavity of the water storage tank 21 through a leaking hole. The drainage groove 25 is convenient for draining the water sprayed from the nozzle 21 into the water storage tank 21 .

[0027] When the grinding wheel 14 is in motion, the two ends of the screw rod 5 are aligned with the pressure plate 6, and the crank 7 is turned to drive the pressure plate 6 to move in the direction of the screw rod 5 to be ground and press it on its end to fix it. The grinding mechanism 12 is driven by the driving mechanism 9 to move the surface of the screw rod to be ground to grind. During the grinding process, when it is necessary to change the grinding surface of the screw rod to be ground, the stud 14 can be screwed in the reverse direction to drive the moving rod 15 to move forward, thereby driving the two arc-shaped pressure blocks 17 away from the two rotating seats 4 to release the limit of the rotating seat 4, and then the screw rod to be ground is rotated. After adjusting the grinding surface, the stud 14 is screwed forward so that the two arc-shaped pressure blocks 17 press the two rotating seats 4 to limit and fix the rotating seat 4. There is no need to disassemble and assemble the screw rod to be ground back and forth, which saves time and effort and greatly improves the working efficiency of the lifting platform screw grinding.
