The 'tool' in the field of mechanical production and processing is production process technological equipment: refers to the collective term for the various tools used in the manufacturing process. The tool comprises a cutter, a clamp, a die, a measuring tool, a checking tool, an auxiliary tool, a bench tool, a station tool and the like.

The machining tool for the base generally comprises a base, a disc and a cutter. The upper end and the lower end of the processed engine base with the cover are cylindrical. When the base with the cover is machined, a worker firstly coincides the axis of the cylinder at the lower end of the base to be machined with the axis of the rotating shaft of the disc, places the base on the disc, and adjusts and fixes the position of the knife to enable the knife to be in contact with the surface of the upper end of the base to be machined. The periphery of the disc is enabled to rotate around the axis of the disc at a constant speed, and the machine base to be machined is driven to rotate around the axis of the lower end cylinder, so that the upper surface of the machine base to be machined is polished. And (4) polishing the upper surface of the base, turning the base with the cover up and down, repeating the steps, and processing the lower surface of the base. In the grinding process, the machine base to be machined is impacted by grinding knives and often moves in the horizontal direction, so that the axis of a cylinder of the machine base deviates from the axis of a rotating shaft of a disc, the machining precision is influenced, and the machine base to be machined needs to be often repositioned in the machining process, and the working efficiency is influenced.

Therefore, a coaxiality machining tool for the base with the cover is needed to be provided, so that the coaxiality machining precision of the base with the cover is improved, and the working efficiency is improved.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model provides a following technical scheme: the coaxiality machining tool for the base with the cover comprises a base, a disc and a cutter, wherein the disc is placed on the base, limiting rods are arranged on the periphery of the disc and symmetrically arranged around the central axis of the disc, and the limiting rods are parallel to the central axis of the disc; the upper end part of the limiting rod is provided with a bolt, the bolt is connected with a limiting sheet for clamping the machine base to be processed, the limiting sheet and the upper end part of the limiting rod are connected with bolts, and the bolts penetrate through the limiting sheet and are connected with the top end of the limiting rod; the upper surface of the disc is provided with a limiting boss, the limiting boss is positioned at the center of the disc, and the limiting boss is coaxial with the disc.

The beneficial effect of this scheme lies in:

1. the coaxiality of the base with the cover during processing is ensured, the processing precision is improved, and the rejection rate is reduced;

2. in the machining process, workers do not need to frequently adjust the position of the workpiece, so that the production efficiency is improved;

3. time cost and labor cost are reduced, and economic benefits are improved.

Furthermore, the limiting boss is a cylinder, and the radius of the bottom surface of the cylinder is 1mm smaller than that of the bottom surface of the stand to be processed. In the machining process, the limit boss limits the horizontal displacement of the machine base to be machined within the allowable range of machining errors; the radius of the bottom surface of the cylinder is smaller than that of the bottom surface of the stand to be processed by 1mm, so that the stand to be processed can be conveniently assembled and disassembled, and the limit boss and the stand to be processed are prevented from being worn due to assembly and disassembly.

Furthermore, the outer wall of the limiting boss is uniformly covered with rubber bumps. If directly set spacing boss bottom surface radius to equal with waiting to process the frame radius, cause spacing boss side and wait to process the frame inner wall during the installation and closely laminate, in the installation, because frictional force acts on, the installation difficulty, spacing boss lateral wall also often fish tail waits to process the frame inner wall. The rubber bumps uniformly covered outside the limiting bosses protect the inner wall of the stand to be processed from being scratched by the limiting bosses in the loading and unloading process; meanwhile, the rubber bumps are tightly plugged in the limiting bosses and the base to be processed in the processing process, so that friction force is provided for the base to be processed, and the base to be processed is prevented from moving in the horizontal direction relative to the disc.

Further, the upper surface of the limiting boss is connected with a clamp; the clamp is cylindrical, the clamp and the limiting boss are coaxially arranged, and the radius of the clamp is smaller than that of the limiting boss; clamping grooves are evenly formed in the circumferential direction of the clamp, and fan blades are clamped in the clamping grooves. The chip breaking that treats processing frame surface production is ground to whetting a knife falls back to fast moving frock on, draws the flower easily and treats processing frame and disc surface, and in the course of working, the fan blade provides outside wind-force, blows the chip breaking away from the disc and treats the processing frame, when the protection is treated processing frame and frock and is not by the chip breaking fish tail that drops when fast rotating, has also reduced the work load of later stage manual work clearance chip breaking.

Furthermore, the number of the clamping grooves is 6, and the number of the fan blades is 1-6. If the wind generated by the fan blades in the processing is too large, the speed and the distance of broken chips are high, people are easily injured, and the broken chips are not easy to clean; if the generated air volume is too small, the function of blowing the broken chips away from the tool cannot be achieved. The air quantity required by different processing production can be obtained by freely increasing or decreasing the quantity of the fan blades clamped on the clamping grooves.

Furthermore, the middle part of the clamp is provided with a rotating shaft which penetrates through the disc and the base. The disc is driven by the rotating shaft to drive the clamp to rotate.

Further, a first motor is connected below the disc. The requirement of processing bases to be processed with different weights is met by adjusting the rotating speed of the motor.

Furthermore, a second motor is externally connected to the lower part of the rotating shaft. The second motor rotates relative to the first motor, so that the fan blades have higher relative rotating speed relative to the base to be processed, and the rotating speed can be adjusted according to actual requirements.

Furthermore, two limiting rods are arranged on two sides of the disc respectively, and the two limiting rods on the same side are arranged along the radial direction of the disc. Because the two points determine a straight line, the two limiting rods are arranged on the same side, and the upper end point connecting line limits the limiting piece hinged with the limiting rod to keep static relative to the limiting piece in the horizontal direction through the bolt.

Furthermore, the outer surface of the limiting sheet is provided with a rubber block which can slide back and forth along the limiting sheet. The rubber block tightly blocks the gap between the limiting piece and the machine seat to be processed, so that the machine seat to be processed and the limiting piece are prevented from moving relatively. Before and after processing, the rubber block slides along the direction of the limiting piece, and the limiting piece is installed and detached on the base to be processed.

The first limiting rod 11 and the second limiting rod 12 are positioned on the same side of the disc; the third limiting rod 13 and the fourth limiting rod 14 are positioned on the same side of the disc; the second limiting rod 12 and the third limiting rod 13 are symmetrical about the disk rotating shaft 8, and the first limiting rod 1 and the fourth limiting rod 14 are symmetrical about the disk rotating shaft 8. Each limiting rod is parallel to the disc rotating shaft 8.

The first bolt 23, the second bolt 24, the third bolt 25 and the fourth bolt 26 are connected with a limiting piece 7 for clamping the base 6 to be processed together, and the limiting piece 7 is sequentially hinged to the upper end parts of the first limiting rod 11, the second limiting rod 12, the third limiting rod 13 and the fourth limiting rod 14 through the first bolt 23, the second bolt 24, the third bolt 25 and the fourth bolt 26; the middle part of the upper surface of the disc 2 is vertically connected with a limit boss 9 through a rotating shaft 8.

In the processing process, the disc 2 rotates around the central shaft of the disc 2 under the driving of the first motor 10, and the first limiting rod 11, the second limiting rod 12, the third limiting rod 13 and the fourth limiting rod 14 which are arranged on the periphery of the disc 2 drive the machine base 6 to be processed, which is clamped by the limiting rods 7, to rotate around the axis of the disc 2 through the limiting rods 7 connected with the limiting rods. The four limiting rods, the limiting sheet 7 and the base 6 to be processed are relatively static, so that the circle center of the cross section of the base 6 to be processed is always kept on the axis of the disc 2; the lower bottom surface of the machine base 6 to be processed is tightly attached to the disc 2, the diameter of the bottom surface of the limiting boss 9 is the same as the inner diameter of the bottom surface of the machine base 6 to be processed, so that the machine base 6 to be processed is prevented from moving in the horizontal direction in the processing process, and the center of the bottom surface of the machine base 6 to be processed is always kept on the axis of the disc 2; because the circle center of the cross section of the machine seat 6 to be processed and the circle center of the lower bottom surface are always kept on the axis of the disc 2, the principle that a straight line is determined by two points can be known as follows: the circle center of the cross section of the machine base 6 to be processed and the circle center of the upper bottom surface of the lower bottom surface are always on the axis of the disc 2; and the reverse turning is carried out, so that the machine base 6 to be machined and the disc 2 are always coaxial in the machining process.

The limiting boss 9 is a cylinder, and the radius of the bottom surface of the cylinder is 1mm smaller than that of the bottom surface of the machine base 6 to be processed. In the machining process, the limit boss 9 limits the horizontal displacement of the machine base 6 to be machined within the allowable range of machining errors; the radius of the bottom surface of the cylinder is smaller than that of the bottom surface of the machine base 6 to be machined by 1mm, so that the machine base 1 to be machined can be conveniently assembled and disassembled, and the limit boss 9 and the machine base 6 to be machined are prevented from being worn due to assembly and disassembly. The outer wall of the cylindrical limiting boss 9 is evenly covered with rubber bumps 16, if the radius of the bottom surface of the limiting boss 9 is directly set to be equal to the radius of the machine base 6 to be processed, the side surface of the limiting boss 9 is tightly attached to the inner wall of the machine base 6 to be processed during installation, and in the installation process, due to the action of friction force, the installation is difficult, and the side wall of the limiting boss 9 is often scratched to the inner wall of the machine base 6 to be processed. The rubber bumps 16 uniformly covered outside the limiting bosses 9 protect the inner wall of the stand 6 to be processed from being scratched by the limiting bosses 9 in the assembling and disassembling process; meanwhile, in the processing process, the limit boss 9 and the base 6 to be processed are tightly plugged by the rubber bumps 16, so that friction force is provided for the base 6 to be processed, and the base 6 to be processed is prevented from moving in the horizontal direction relative to the disc 2. As shown in fig. 3, the upper surface of the limit boss 9 is connected with a clamp 17 through the rotating shaft 8; the upper surface of the clamp 17 is concentric with the limiting boss 9, clamping grooves 18 are uniformly formed in the horizontal annular direction, and fan blades 19 are clamped in the clamping grooves 18. The 3 sharpenings of whetting a knife polish treat that the chip breaking 20 that the surface of processing frame 6 produced falls back to fast moving's frock, draw the flower easily and treat processing frame 6 and disc 2 surface, in the course of working, fan blade 19 provides outside wind-force, blows off chip breaking 20 from disc 2 and treat processing frame 6, when the protection is treated processing frame 6 and frock and is not by the chip breaking 20 fish tail that drops when fast rotating, has also reduced the artifical work load that clears up chip breaking 20 in later stage. The number of the clamping grooves 18 is 6, and the number of the fan blades 19 is 1-6. If the air volume generated by the fan blade 19 in the processing is too large, the speed is high and the distance is long when the broken chips 20 fly out, so that people are easily injured and the cleaning is difficult; if the generated air volume is too small, the function of blowing the broken chips 20 away from the tool cannot be achieved. The air quantity required by different processing production can be obtained by freely increasing or decreasing the quantity of the fan blades 19 clamped on the clamping grooves 18. The contact part of the clamp 17 and the rotating shaft 8 is provided with threads, the contact part of the surface of the rotating shaft 8 and the clamp 17 is provided with threads matched with the threads of the limiting boss 9, and the contact part of the surface of the limiting boss 9 and the disk 2 is smooth.
