DETAILED DESCRIPTION
[0022] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0023] Figure 1-Figure 4 An embodiment of the utility model is an adjustable workpiece grinding structure, including an operating table 1, the top surface of the operating table 1 is fixedly connected to a grinding mechanism 2, the surface of the operating table 1 is provided with a clamping assembly 3 through a pad, the top surface of the operating table 1 is provided with a dust cover 4, and the top surface of the dust cover 4 is provided with a dust plate 8, the top surface of the dust plate 8 is axially symmetrically provided with a dust suction port, and the top surface of the dust suction port is provided with a dustproof assembly 5.
[0024] The specific problem addressed by this specific embodiment is to solve the problem that the extension and contraction force of the cylinders cannot be finely adjusted when the workpiece is squeezed and fixed by using multiple cylinders. For some thinner workpieces, excessive extension and contraction force of the cylinders will cause squeezing and deformation of the workpiece, which is easy to cause damage to the workpiece, and the practicality and versatility of the clamping structure are poor. The utility model uses a gear 36 to drive the meshing tooth plates 33 on both sides to move in opposite directions, and drives the clamping plates 35 fixed on the top surface by the connecting block 34 to approach each other, so as to squeeze and fix the workpiece placed in the placement groove 31. The effect of damaging the workpiece due to excessive squeezing can be avoided by flexibly changing the rotation force of the gear 36.
[0025] The clamping assembly 3 includes a placement groove 31 arranged on the top surface of the pad, and the inner bottom wall of the placement groove 31 is provided with a groove, the interior of the groove is axially symmetrically provided with a bracket 32, the interior of the bracket 32 is slidably connected with a tooth plate 33 through a slider, the top surface of the tooth plate 33 is provided with a connecting block 34, and the top surface of the connecting block 34 is provided with a clamping plate 35, the side of the tooth plate 33 is meshed with a gear 36 for transmission, in this specific embodiment, the bottom surface of the gear 36 is provided with a metal hose 6, and one end of the metal hose 6 is provided with a twist block for the user to exert force, and a rotating hole for accommodating the metal hose 6 is provided inside the pad. The metal hose 6 is rotated to drive a fixed gear 36 to rotate. The tooth plates 33 meshing on both sides of the gear 36 slide on the surface of the bracket 32 through the sliders arranged on the back. The movement of the tooth plates 33 will drive the clamping plate 35 fixed on the top surface through the connecting block 34 to follow the movement. The two clamping plates 35 approach each other during the movement, and squeeze and fix the workpiece placed in the placement groove 31. According to the actual conditions such as the material and thickness of the workpiece, the force of rotating the metal hose 6 is changed, so that the squeezing force of the clamping plate 35 on the workpiece can be changed, which plays a role in avoiding excessive squeezing and damage to thinner and softer workpieces.
[0026] In this specific embodiment, the dustproof component 5 includes a placement plate 51 fixedly connected to the top surface of the dust suction port, and the placement plate 51 is fixed with a negative pressure impeller 52 through a ventilation hole opened in an axisymmetric manner on the top surface, a negative pressure groove 53 is provided on the top surface of the placement plate 51, and a discharge port is opened on the top surface of the negative pressure groove 53, and a waste material groove 543 is provided on the top surface of the negative pressure groove 53, and vertical plates are provided on both sides of the discharge port, and a cover plate 542 is installed on the side of the vertical plate through a hinge 541;
[0027] Through the setting of the dust-proof component 5, the dust generated when the workpiece is polished will float inside the dust cover 4, and the negative pressure impeller 52 will rotate, so that the air inside the negative pressure groove 53 will be quickly discharged to generate negative pressure. At the same time, the high-speed gas will entrain the dust to push the cover 542 open, and the dust in the air in the dust cover 4 will be sucked into the waste groove 543 connected to the top surface of the negative pressure groove 53 through the discharge port. When not working, the cover 542 rotates through the hinge 541 under the influence of gravity to seal the discharge port to prevent dust from falling into the dust cover 4, thereby achieving the purpose of facilitating the dust removal of the dust generated by polishing and preventing dust from escaping into the air and polluting the surrounding air environment.
[0028] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
