Description

Technical Field

[0001] The utility model belongs to the field of mechanical parts processing, and specifically relates to a polishing device for mechanical parts processing. Background Art

[0002] The polishing device of the prior art lacks a structure for clamping parts, and the user needs to hold the parts for polishing operations. The polishing device will cause wear and tear on the hands of the user, which is dangerous. The clamping operation of the parts is relatively cumbersome. When multiple parts need to be polished, the parts cannot be quickly and firmly disassembled and assembled, affecting the polishing efficiency.

[0003] The Chinese patent with the publication number CN215092827U discloses a polishing device for machining mechanical parts; it includes a bracket, a box is fixedly installed on the upper end of the bracket, polishing sand is contained in the box, and multiple groups of equally spaced first motors are fixedly installed on the outer side of the lower side wall of the box, and the drive output ends of the multiple groups of the first motors are respectively connected to the multiple groups of transmission shafts. The utility model has the transmission shafts connected to the transmission of the multiple groups of second motors all pass through the mutually corresponding support plates and are fixedly connected with support rods, and the central axes of the multiple groups of equally spaced bearings fixedly installed on the outer side walls of the upper side walls of the multiple groups of support plates are all fixedly connected with support rods, and the multiple groups of support rods at the upper ends of the multiple groups of support plates are all connected through transmission belts. When we drive the first motor and the second motor at the same time, we can not only rotate the multiple groups of support plates, but also rotate the multiple groups of support rods, so that the polishing of the mechanical parts in the multiple groups of material plates is more complete, which is conducive to more practical use of the polishing device for machining mechanical parts.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a polishing device for machining mechanical parts, thereby solving the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0007] A polishing device for machining mechanical parts, comprising: a base, a polishing structure is arranged on the top surface of the base, a bracket is fixedly connected to the surface of the base, a threaded hole is opened on the top surface of the bracket, a pressing structure is connected to the inner thread of the threaded hole, a buckle structure is fixedly connected to one side of the pressing structure, and a clamping structure is fixedly connected to the other side of the pressing structure;

[0008] The clamping structure includes a mounting block fixedly connected to the side of the pressing structure, the interior of the mounting block is fixedly connected to a rotating structure, the side of the mounting block is provided with rotating holes in a circular array, the interior of the rotating holes is rotatably connected to a clamping block, and the surface of the clamping block is rotatably connected to a clamping plate.

[0009] Optionally, a threaded hole is provided on the side of the clamping block, and the internal thread of the threaded hole is connected to an extrusion block. The position of the extrusion block protruding from the side of the clamping block can be adjusted according to the size of the part, so as to facilitate extrusion and fixation of parts of different sizes.

[0010] Optionally, the rotating structure includes an internal threaded tube fixedly connected to the inside of the mounting block, the internal thread of the internal threaded tube is connected to a threaded block, and the side of the threaded block is fixedly connected to a turning handle. By turning the turning handle, the threaded block can be driven to rotate, so that the internal threaded tube threadedly connected to its surface drives the mounting block to move, and the mounting block pushes the clamping block to rotate, so that the parts can be quickly squeezed and fixed, and the operation is more convenient.

[0011] Optionally, the pressing structure includes a screw rod threadedly connected to the inside of the threaded hole, one end of the screw rod is sleeved with a bearing, and the bottom surface of the bearing is fixedly connected to a clamping plate.

[0012] Optionally, the top end of the screw rod is fixedly connected to a rotating disk, the side of the rotating disk is provided with auxiliary rods in a ring array, and the top surface of the rotating disk is provided with anti-slip beans for increasing friction. By turning the rotating disk, the screw rod can be driven to rotate, making the rotation of the screw rod easier. At the same time, the anti-slip beans provided on the top surface of the rotating disk can increase its surface friction to avoid the situation of slipping from the hand.

[0013] Optionally, the snap-fit ​​structure includes a fixing box fixedly connected to the side of the clamping plate, the interior of the fixing box is axially symmetrically fixedly connected with an elastic clamping plate, the top of the elastic clamping plate is provided with a rotating groove, the interior of the rotating groove is rotatably connected with a roller, and one end of the part is pressed between the two elastic clamping plates to preliminarily fix the part, thereby preventing the part from falling off during the operation of fixing the other end of the part to the clamping structure, and making operation more convenient for users.

[0014] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0015] 1. Through the setting of the clamping structure, one end of the part is placed on the side of the mounting block, and the handle is turned to drive the threaded block to rotate. The inner thread tube connected to the surface of the threaded block moves and drives the mounting block fixed on the surface to move, so that the clamping block in the rotating hole on the side of the mounting block is pushed, and the extrusion block connected to the threaded side of the clamping block is moved toward the center of the mounting block to squeeze and fix the placed parts. The parts can be conveniently clamped and loosened by simply turning the handle, thereby achieving the effect of quickly replacing the parts to be polished and improving the polishing efficiency.

[0016] 2. Through the setting of the downward pressing structure, after the parts are clamped between the clamping structure and the buckle structure, the rotating disk is pulled to drive the screw rod to rotate inside the bracket and move downward, so that the clamping plate fixed on the ground is driven to move downward through the bearing sleeved at one end, so that the clamped parts gradually approach the polishing structure, and the parts are polished. There is no need to hold the parts for polishing, thereby avoiding the wear of the hands of the user by the polishing structure when holding them, which may cause safety hazards.
